IntroductionThe mammalian kinesin superfamily proteins (KIFs) are microtubule and ATP-dependent molecular buy levitra online motors, which were first identified in 1985 as axonal transporters in squid and bovine brains.1 Forty-five different kinesin family member (KIF) genes were identified in the mouse genome so far, 44 of which are present in the human genome. Phylogenetic analysis based on sequence homology between the human and the mouse genome led to the classification of KIF genes into 16 families, from kinesin-1 to kinesin-14B (figure 1).2 The first kinesins discovered belong to the kinesin-1 family (KIF5A, KIF5B and KIF5C), and they form a heterotetramer of two heavy chains and two light chains (KLC1-4).2 KIF genes encode KIFs, a specific class of motor proteins generating intracellular motility by driving directional transport of various cargoes such as organelles, protein complexes and mRNAs along the microtubule system.2 Studies using knockout mouse models by Hirokawa and colleagues significantly contributed to elucidate the roles of kinesins in mammalian physiology. Their role in transport is fundamental to cellular logistics and performance, and the molecular motors are not only effectors of signal transduction cascades but also transport and/or bind to important signal transduction molecules to actively modulate their function.3Phylogenetic tree of mammalian kinesin superfamily genes identified in the human (and mouse) genome and classified in 16 subfamilies (from kinesin 1 to 14B) (adapted from Hirokawa et al 3)." data-icon-position data-hide-link-title="0">Figure 1 Phylogenetic tree of mammalian kinesin superfamily genes buy levitra online identified in the human (and mouse) genome and classified in 16 subfamilies (from kinesin 1 to 14B) (adapted from Hirokawa et al3).The first kinesins were observed in the context of axonal transport in neurons, and a novel disease entity of âmotorâproteinopathyâ was proposed for the pathogenesis of axonal neuropathies in 2001.4 Due to their role in cellular membrane trafficking, however, kinesins are essential for the functioning of many polar cell types, such as neurons, epithelial cells, sperm cells or stem cells during organogenesis.
Kinesins also play a fundamental role in cell-cycle dynamics, both during mitotic and meiotic processes. They regulate chromosomal condensation and alignment, spindle formation, cytokinesis and buy levitra online cell-cycle progression.5 It is estimated that about a dozen kinesins are involved in the cell cycle. Among these, there is a specific subclass of chromokinesins (kinesin 4 and kinesin 10 family) which are able to bind chromosomes.6 Recently, KIFs were discovered to act as microtubule stabilisers (KIF26A and KIF21A) and depolymerisers (KIF2A and KIF2C), activities which are important for both cellular morphogenesis and mammalian development, playing a role in neuronal and axonal morphology and ciliogenesis.7Alterations in motor kinesins are leading to human disease by various pathological mechanisms, including cancer and multifactorial and monogenic disorders.
Variants in 18 out of the 44 human KIF genes buy levitra online were identified to cause monogenic disorders, following different modes of Mendelian inheritance and associated with a wide spectrum of clinical signs. These range from lethal and multiple to isolated congenital anomaliesâincluding birth defects potentially detectable in the foetal period by current prenatal imaging studiesâto postnatally apparent neurodevelopmental disorders, intellectual disability and neurological conditions.We will review the current state of knowledge of the biological processes kinesins are involved in and discuss their emerging role in human disease, particularly in birth defects and congenital anomaly syndromes. Birth defects remain a leading cause of perinatal lethality in industrialised countries.8 Structural anomalies are recognised with increasing reliability during early pregnancy by the use of high-resolution ultrasound technologies, thus raising questions about diagnosis, aetiology, prognosis and recurrence risk, particularly in the presence of more than one anomaly, which most likely indicates a genetic aetiology.
We identify recurrent phenotype buy levitra online patterns caused by alterations in KIF genes, and we outline the complexity of phenotypeâgenotype correlations mirroring the processes of intracellular microtubule-mediated transport and movement, in which kinesins play a fundamental role. There are likely many more relationships between the clinical signs and the genetic variants to be identified in the future, and the functional network of kinesins and their role in human disease need to be further elucidated. We propose to introduce the term âkinesinopathiesâ for this group of buy levitra online conditions, which are phenotypically and genetically overlapping and characterised by the functional impairment of a specific group of molecular motors.
We hope that their systematic approach leads to a better recognition in clinical practice, as well as in genome-wide sequencing for diagnosis and research, and opens strategies for the future development of molecular therapies.KIF structureAll KIFs have a phylogenetically well-conserved motor domain head, consisting of an ATP-binding motif and a microtubule-binding domain. Depending on the position of the motor domain, kinesins can be subdivided into N-kinesins (amino-terminal motor domain), M-kinesins (middle-region motor domain) and C-kinesins (carboxy-terminal motor domain).2 Most kinesins belong to the N-kinesin subgroup, but members of the kinesin 13A family (figure 1) belong to the M-kinesin subtype, while KIF1C, KIF2C and KIF3C belong to the C- kinesin subfamily.3 Both N-kinesins and buy levitra online C-kinesins are responsible for plus end and minus end-directed motility, M-kinesins for depolymerisation of microtubules in tubulin molecules. However, there are a few exceptions to this categorisation.9 The motor domain head attaches to the neck, the coiled coil stalk and the tail.
The kinesinsâ neck is family-specific and responsible for the direction of motility or regulation of activity. The coiled coil stalk and buy levitra online tail are involved in kinesin dimerisation and/or interactions with cargoes. Kinesins typically use scaffold proteins and adaptor proteins to bind their cargoes but can sometimes bind the cargo directly.
Scaffolds and adaptors might also have regulatory roles in kinesin-driven intracellular transport, that buy levitra online is, recognising specific cargoes and regulating their loading and unloading.3Role of KIFs in physiology and diseaseThe application of genome-wide sequencing for gene identification in research or for clinical diagnostic purposes significantly contributes to the identification of KIF candidate genes. Genotypeâphenotype correlations in KIF gene-related disorders, together with functional and animal studies, continue to elucidate the complex involvement of KIFs in human developmental pathways and disease. Table 1 summarises the monogenic conditions caused by variants affecting the function of KIF genes.View this table:Table 1 Specific monogenic disorders caused by variants affecting the function of KIF genesView this table:Table 2 Summary of phenotypes and genotypes of KIF149 26 30 31The kinesinsâ functions in physiological processes, however, are complex buy levitra online and still incompletely understood, but their role in cell-cycle progression and regulation, including both meiosis and mitosis, in intracellular trafficking, axonal transport, microtubule activity and ciliogenesis, is increasingly studied.

CNS, central nervous system.Kinesins play a pivotal role during early buy levitra online development and organogenesis. Microcephaly is one of the most frequently associated clinical signs, mirroring a defect in the regulation of the final number of neurons during development.10KIF4A is a motor protein that translocates PRC1, a cytokinesis protein, to the ends of the spindle microtubules during mitosis, regulates the PARP1 activity in brain development and the survival of neurons, and is a member of the L1CAM recycling pathway. Variants in L1CAM buy levitra online cause X-linked isolated and syndromic hydrocephalus.
KIF4A was recently proposed as a candidate gene for hydrocephalus.11KIFs are involved in neuronal branching, and microtubule depolarisation, operated by KIF2A M-kinesin, was suggested to suppress collateral branch extension during brain development, leading to anomalies of cortical development, including agyria and pachygyria, subcortical band heterotopia and corpus callosum anomalies.12Functional disruption of KIF genes in knockout mice often results in embryonic lethality, for example, for Kif18A, Kif10, Kif3A, Kif3B and Kif5B,13â17 highlighting the importance of kinesins in embryonic and foetal development. A study on KIF16B demonstrated that microtubule-based trafficking is responsible for early development and stem cell survival.18 KIF26B is essential in kidney development, contributing to the adhesion of mesenchymal cells to the ureteric bud.3 KIF26A was suggested to play a role in enteric nervous system development, because knockout mice develop a megacolon and enteric nerve hypoplasia,19 and to negatively regulate nociceptive sensation.20A significant number of KIFs play a prominent role in ciliogenesis and cilia function. They regulate cilia length, ciliary assembly/disassembly and can have motile cilia-specific functions.21 Some KIFs, specifically found in primary cilia (PC), regulate the length of the axoneme and its disassembly when re-entering the cell cycle.KIF7, also a key component of the Hedgehog signalling pathway, is responsible for cilia length regulation through suppression of microtubule polymerisation.7 KIF7 variants cause hydrolethalus, acrocallosal, and Joubert and Al-Gazali-Bakalinova syndromes.22 Kif2A knockout buy levitra online mice have severe brain defects, and KIF2A variants in humans lead to microcephaly because of cell-cycle delay in cellular progenitors resulting from cilia disassembly defects.
KIF24, belonging to the same kinesin 13 family, plays a role in both microtubule depolymerising activity and regulation of the early steps of ciliogenesis. Other PC-related KIFs recently buy levitra online identified are KIF5B, KIF1C and KIF13B, and a potential role in cilia was hypothesised for KIF11 and KIF14.KIF3 protein complex (KIF3A-KIF3B-KAP3 heterotetramer) is a molecular motor necessary for intraflagellar transport (IFT) but is also involved in ciliogenesis of motile cilia. Kif3a-knockout or Kif3b-knockout mice are prenatally lethal, exhibiting anomalies similar to ciliopathy phenotypes, including the disturbance of leftâright body determination.3KIF19A is localised at the tip of motile cilia and performs motor and microtubule-depolymerising activities during IFT.
Kif19a-knockout mice present with hydrocephalus and female infertility, common signs in ciliary defects, due to abnormally elongated cilia with altered motility, not able to generate proper fluid flow.9Further KIFs, which may have specific roles in motile cilia, are KIF27, KIF9, KIF6 and buy levitra online KIF18B. Regarding the involvement of numerous KIFs in cilia-related processes, it is not surprising that many disorders caused by variants affecting KIF gene function are presenting with anomalies reminiscent of ciliopathies.Kinesin motors have a fundamental role in neuronal function, as they are responsible for the transport of synaptic vesicle precursors and transmitter receptors along axons and dendrites from the neuron body.3 Molecular motor activity as for KIF1A, KIF5 and KIF17 is important for higher brain functions, such as learning and memory through regulation of synaptic transmission.5 Dysfunction can be associated with intellectual disability and global developmental delay (table 1).Impaired function can also result in peripheral neuropathies (KIF5A, KLC2, KIF1A and KIF1B) and ocular motility disorders (KLC2 and KIF21A)23 24 when axon elongation in the peripheral nervous system and optic nerve is affected. KIF5A variants are associated with epileptic phenotypes both in humans and mice25 because the transport of neurotransmitter receptors is disturbed and inhibitory regulation is altered.Due to their role in cell-cycle regulation, kinesins are important in male spermatogenesis and female oogenesis.
They are involved in all steps of spermatogenesis 26 buy levitra online and, based on previous animal studies, they may represent a potential target to treat male infertility. In female meiosis, 13 KIF genes were studied in animal models. There is some evidence that kinesin expression is vulnerable to maternal ageing and environmental factors, such buy levitra online as oocyte cryopreservation and alcohol consumption.
It may be promising to expand research in this field in order to clarify the mechanisms and factors contributing to oocyte quality decline.27Many kinesins were extensively studied in the fields of cancer development, progression and therapy. Deregulation of the mitotic kinesins by both overexpression and decreased expression causes cancer progression or can be a prognostic marker in various buy levitra online tumours.28 The cell-permeable small-molecule mitotic inhibitor monastrol was discovered in 199929 and was shown to arrest cells in mitosis by specifically inhibiting KIF11, a kinesin important for spindle bipolarity. The bipolar mitotic spindle is replaced by a monoastral microtubule array surrounded by a ring of chromosomes, which gave the inhibitor its name.
The mitotic spindle is now a well-known target of chemotherapy, and inhibitors of the mitotic kinesins KIF11, KIF10 and KIF1C are being studied for this purpose.28 30 The buy levitra online redundancy of some kinesins allows them to escape pharmacological inhibition. For example, in the absence of KIF10, KIF15 is able to replace all of its essential functions in spindle assembly. Cilia-related KIF7, KIF13B and KIF27 are involved in SHh signalling and may be a future target in cancer research.28Some kinesins confer susceptibility to a range of multifactorial, metabolic and neurodegenerative conditions.
KIF13B contributes to the enhancement of endocytosis of low-density lipoprotein (LDL) receptor-related protein 1 that is involved in the recognition and internalisation of LDL and factor VIII buy levitra online. Kif13b-knockout mice have hypercholesterolaemia and higher factor VIII serum levels.5 KIF12 is implicated in the pathogenesis of type 2 diabetes, protecting pancreatic β cells from the oxidative stress caused by nutritional excess.5 Variants in KIF1B or KIF21B confer susceptibility to multiple sclerosis (OMIM %612596, #126200).31 32 KIF5A was associated with Amyotrophic lateral sclerosis (OMIM #617921).33 KIF3 complex and KIF17 were recently uncovered to be involved in schizophrenia.34 35 Further studies, however, are needed to clarify the precise role of KIFs in neurodegenerative processes and psychiatric conditions.KIF14 -related birth defects. Lessons learntAdvances in next-generation sequencing technologies have revolutionised our understanding of Mendelian disorders, including birth defect phenotypes, by sequencing the coding buy levitra online genome (exome) or entire genome at an unprecedented resolution in a comparably short time span.
The technology has been extensively used for gene identification approaches in research for many years, enabling unparalleled genotypeâphenotype correlations and the definition of novel pathways of related genes and disorders at an accelerated pace, traditionally focusing on postnatal disorders. Filges and Friedman36 postulated that a number of novel disease genes causing birth defects could be identifiable through the investigation of lethal foetal phenotypes since they would represent the extreme end of allelic buy levitra online milder and viable postnatal phenotypes with less specific or recognisable anomaly patterns. Based on embryonically or perinatally lethal mouse models (www.informatics.jax.org and www.dmdd.org.uk), it is estimated that knockout variants in about 30% of human protein coding genes may present with a phenotype of early lethality.
The identification of KIF14 loss of function variants in fetuses with a lethal multiple congenital anomaly syndrome and the subsequent description of the allelic postnatal viable phenotype and further functional characterisation of KIF14 in developmental processes are recent examples of how to study those embryonic lethal phenotypes in order to understand the role of genes for which little to nothing is known.Filges et al identified autosomal recessive compound heterozygous loss of function variants in KIF14 using family-based exome sequencing in a recurrent severe lethal phenotype (OMIM #616258). It was the first human phenotype reported due to variants in the human KIF14 gene (figure 3).37 The two affected siblings presented with intrauterine growth retardation (IUGR), oligohydramnios, severe microcephaly, renal cystic dysplasia or agenesis, genital tract malformations (uterine hypoplasia and vaginal atresia), as well as cerebral and cerebellar hypoplasias with partial or total agenesis of buy levitra online the vermis, arhinencephaly, agenesis of occipital lobes/corpus callosum at second trimester ultrasound scan. Cross-species comparison to the laggard spontaneous mice mutant, characterised by homozygous variants of the Kif14 gene,38 confirmed a phenotypical overlap.
An increased number of binucleated cells in the tissue histology of the two fetuses were in concordance with the key role of KIF14 during mitosis participating in chromosomesâ congression and buy levitra online alignment, as well as in cytokinesis39 and the observation of binucleated cells as a consequence of failed cytokinesis in mammalian KIF14 knockdown cells. During cytokinesis, PRC1 localises KIF14 at the central spindle and midbody, which in turn recruits citron rho-interacting kinase (CIT) to the midbody. CIT, in turn, acts as a buy levitra online negative regulator of KIF14 activity.
Knockdown of KIF14 in mammalian cells results in impaired localisation of CIT during mitosis.40Structure of KIF14 and summary of all published KIF14 variants affecting function.10 37 41 42 The N-terminal region (aa 1â356) is important for its interactions with PRC1 and the proteinâs localisation at the central spindle and midbody.

Aa, amino acid.Filges et al pointed out that KIF14 should be considered a candidate gene for viable postnatal phenotypes, including isolated microcephaly.34 Additional individuals with autosomal recessive variants in KIF14 and isolated primary microcephaly were then described9 41 42 (table 2).Impaired cytokinesis, increased apoptosis and reduced cell motility were confirmed in cells from the described patients, pointing to a new cellular pathway in the pathogenesis of microcephaly.43 Apart from one case with small kidneys with increased echogenicity, none of these 18 patients had associated kidney anomalies. However, a targeted exome sequencing study in 204 unrelated buy levitra online patients with congenital anomalies of the kidney and urinary tract (CAKUT) reported two more cases of renal anomalies, bilateral hypoplasia or agenesis, caused by KIF14 variants.44 Further nine cases had an associated renal phenotype, which ranged from bilateral renal agenesis to cystic or non-cystic renal hypodysplasia.42 Table 2 and figure 3 summarise KIF14 variants and the associated phenotypes.
Loss of function variants more likely lead to multiple congenital anomalies, while hypomorphic variants result in a milder phenotype without renal involvement, although phenotypeâgenotype correlations remain preliminary for the time being.The phenotypical spectrum ranging from isolated primary microcephaly to congenital anomalies reminiscent of ciliopathy phenotypes suggested a complex role for KIF14 in developmental processes and raised a number of questions about the relationship between its established role in cell division and its possible function in ciliary pathways. Functional studies of absent KIF14 protein in the development of human foetal tissues and mutant zebrafish provided evidence for similarities and differences between mitotic events occurring during proliferation in the development of both brain and kidney.42 The observation that KIF14-stained midbodies accumulate within the lumen of the branch buy levitra online tips of ureteric buds in human foetal kidneys provided a key clue to better understand the mechanism through which the loss of KIF14 affects both brain and kidney development in humans. It was previously demonstrated that the secretion and accumulation of midbody remnants in the cerebrospinal fluid in mice during the early stages of brain development correspond to the amplification of neural progenitors.45 Kif14 mutant zebrafish phenotypes supported the hypothesis of a potential role for KIF14 in cilia.
In vitro and in vivo analyses suggested that loss of kif14 causes ciliary anomalies through an accumulation of mitotic cells in ciliated buy levitra online tissues but failed to establish a direct functional link.21 42 Further mechanisms remain to be elucidated. Overexpression of KIF14 in various types of tumours was suggested to be a possible prognostic marker and a potential target for therapeutic purposes.46Kinesinopathies in birth defect phenotypes. Recurrent themesIn the last few years, an increasing number of variants in KIF genes were described to cause isolated as well as multiple congenital anomalies.
There is a huge variability of phenotypes caused by buy levitra online variants even within the same gene. However, we can identify recurrent clinical signs that should alert the clinician to suspect a KIF gene-related disorder and the molecular geneticist to include KIF genes in multigene-panel and genome-wide sequencing approaches. This will become particularly relevant in prenatal and perinatal medicine, which focuses buy levitra online on the detection of structural anomalies in the fetus and the newborn by using ultrasound and MRI or autopsy when the outcome is lethal.
We have summarised the predominant and recurrent structural anomalies in kinesinopathies reported so far that would likely become apparent during the foetal period in table 3 and the syndromic disorders in table 1.View this table:Table 3 KIF gene-related structural congenital anomalies recurrently described in prenatal phenotypesSupplemental materialConsistent with the kinesinsâ role in the development of the central nervous system (CNS), brain anomalies of various degrees are a frequent clinical sign, particularly microcephaly, but include lissencephaly, polymicrogyria, thinned or agenesis of the corpus callosum, arhinencephaly, cerebral hypoplasia or atrophy, cerebellar hypoplasia or atrophy, brainstem hypoplasia and a molar tooth sign on brain imaging.12 22 37 44 47â51Primary microcephaly can be detected prenatally or at birth12 22 47 48 50 51 and can present as an isolated or syndromic condition as, for example, caused by variants in KIF149 or in KIF11 (microcephaly with or without chorioretinopathy, lymphoedema or mental retardation. OMIM #152950).48KIF7 variants were related to macrocephaly in the presence of congenital hydrocephalus (hydrolethalus syndrome LS2, OMIM # buy levitra online 614120). Isolated hydrocephalus was reported for KIF4A in a single case.11Foetal akinesia and arthrogryposis (KIF5C12, KIF1434 and KIF26B50) are likely secondary to the neurological compromise of the fetus but can also appear as an early sign of abnormal CNS development, which should prompt specialist CNS sonographic and MRI evaluation of the fetus.Further anomalies of the limbs include camptodactyly (KIF26B50), clubfoot (KIF1A51), rocker-bottom feet (KIF26B50) and congenital lymphoedema of the limbs (dorsa of feet, lower extremities and, rarely, hands) in cases with KIF11 gene mutations.48 In particular, KIF7 gene variants have been related to various anomalies of the hands (tapered fingers, fifth finger clinodactyly, brachydactyly, preaxial or postaxial polydactyly, bifid terminal phalanges of the thumbs, spindle-shaped fingers, clinodactyly and soft tissue webbing) and feet (toe syndactyly, preaxial or postaxial polydactyly, and duplicated halluces).22CAKUT and genital anomalies are reported in various kinesinopathies including renal agenesis or hypoplasia (KIF1437 and KIF1252), ureteral hypoplasia (KIF1437), congenital megabladder (KIF1252) and vesicoureteral reflux (KIF1252), uterine hypoplasia and vaginal atresia (KIF1437) and hypospadias and chordae (KIF16B49).IUGR is recurrently detected (KIF5C12, KIF1437, KIF1053, KIF1554 and KIF2A12) and is particularly relevant when occurring simultaneously with one of the other recurrent clinical signs, indicating a potential syndromic KIF-related disorder.
Oligohydramnios or polyhydramnios is most likely secondary to a primary organ anomaly.There are a few kinesinopathy syndromes that have been specifically reported to be lethal, such as the ciliary phenotype (OMIM #616258), caused by variants in KIF1434, and hydrolethalus syndrome (OMIM #614120), caused by variants in KIF7.22 However, lethality is usually closely related to the specific major anomalies, and it can be hypothesised that such a lethal phenotype will exist for all KIF gene-related disorders.Developmental delay, intellectual disability, seizures, and sensory and motor disturbances of the peripheral nervous system, as well as eye anomalies, such as microphthalmy, optic nerve pallor, fibrosis of extraocular muscles and chorioretinopathy, will escape detection in the foetal period but are reported in postnatal patients.Kinesin pathways in birth defectsFunctional studies of kinesins in birth defects are still sparse, and little is known about their networks and pathways. In order to improve our understanding, we used the Ingenuity buy levitra online Pathway Analysis (IPA Qiagen, Redwood City, California, USA) to visualise and analyse the connections between the 13 kinesin motor proteins associated with structural congenital anomalies (KIF5C, KIF1A, KIF1BP, KIF14, KIF16B, KIF7, KIF4A, KIF11, KIF10, KIF26B, KIF12, KIF15 and KIF2A) and in up to 10 of each of their most significant downstream proteins. The connections are defined as proteinâprotein interactions, activation, regulation of binding, expression, localisation, phosphorylation, proteinâRNA interactions, molecular cleavage, ubiquitination, proteinâDNA interactions, inhibition, translocation and transcription.
Figure 3 buy levitra online displays the results. We used the software Gephy55 to look for all possible interactions between all proteins of the network and also used the IPA data to retrieve the canonical pathways involved. Figure 4 and online supplementary material, buy levitra online table 4, summarise the results.
KIF7, KIF14 and KIF12 are located within the same network, and because of multiple connections between themselves and their downstream proteins, it is not surprising that they are all involved in kidney anomalies. IPA data are based on current publications and are therefore subject to bias because proteins that are most interconnected are also most probably those that have been more extensively buy levitra online studied. However, we consider the KIF genes coding for proteins seeming less important within the network to be strong candidates for future studies of human developmental disorders.IPA of the 13 kinesins known to be involved in birth defects with respect to their position in the cell.

IPA, Ingenuity Pathway Analysis.Closing remarks and future perspectivesNovel KIF genes are increasingly identified, and there is a growing body of literature demonstrating the impact of kinesin dysfunction in human disease. We propose to introduce the term kinesinopathies for conditions caused by variants in buy levitra online KIF genes, since recurrent and common functional and phenotypical themes can be observed.
In analogy to ciliopathies56 and rasopathies,57 the delineation of the clinical, genetic and functional hallmarks of kinesinopathies will be important to better recognise these conditions, to understand the pathomechanisms and to ultimately improve the clinical management of the patients. Previously, the unified view of the phenotype characteristics of ciliary dysfunction allowed a tremendous increase in awareness, both in clinic and research, and the further identification of yet unrecognised ciliary disorders and the genes and proteins involved in their pathogenesis.56Remarkable progress was achieved in assigning function to kinesins through their study in isolated and multiple congenital anomaly phenotypes. They are one large superfamily of molecular motors out of three (kinesins, dyneins and myosins), which is of key importance in several fundamental cellular processes using microtubules as rails for directional anterograde intracellular transport, including its regulation and modulating signal buy levitra online transduction.5 Kinesin motors are most important for the movement of chromosomes along the spindles during chromosome segregation, regulation of spindle formation, cell division and cytokinesis.
These essential and broad cellular functions are critical for many physiological processes such as neuronal function and survival, some ciliary functions and ciliogenesis, determination of the left/right asymmetry of our body and regulation of organogenesis, thus explaining the impact and emerging recognition of kinesins in embryonic and foetal development. Defects can result in neuropathies, higher brain functions and structural brain anomalies buy levitra online. Multiple congenital anomalies, including the kidney and urinary tract and limb anomalies, are repeatedly reported.
Microcephaly, which is usually not associated with genes implicated in specific ciliary buy levitra online mechanisms, and CNS anomalies are the most recurrent clinical signs in both the prenatal and postnatal phenotypes described so far. The discovery of the implication of KIF14 in microcephaly further suggested a possible novel role of other microcephaly proteins in cytokinesis. A number of syndromic kinesinopathies present, however, with phenotype patterns reminiscent of ciliopathies.
So far, however, a buy levitra online direct functional impact was confirmed in only a few and could not be demonstrated, for example, for KIF14, despite an overlapping clinical pattern. In turn, ciliopathies are a clinically and genetically heterogeneous group of conditions themselves. Studying tissue and cell type-specific function and expression may help to further define the specific defects related to the individual aberrant kinesin.The pleiotropic nature buy levitra online of human kinesinopathies, however, is just emerging, but their study promises to provide important insights into human developmental pathways.
Seemingly unrelated clinical entities are highlighting a common theme. In a relatively short time span, monogenic KIF-related disorders buy levitra online were identified to present with often severe and lethal antenatal anomalies, with multiple or isolated congenital anomalies, neurodevelopmental and neurological disorders, or an increased susceptibility to multifactorial conditions. We focused on the emerging role of kinesins in structural congenital anomalies because, as illustrated for the KIF14 gene, great potential to decipher allelic viable phenotypes and developmental pathways lies in the study of these human knockout phenotypes at the severe end of the phenotypical spectrum.
Knockout variants in about 30% of human protein coding genes in our genome may present with a phenotype of early lethality, and KIF genes seem to play an important role in such fundamental processes of human development. Identifying and characterising the variants, genes and phenotypes will extend our knowledge on early human development and pathomechanisms, and will ultimately also improve the clinical utility buy levitra online of genome-wide sequencing approaches for prenatal and postnatal application by our increased ability to interpret loss of function and hypomorphic variants alike. Furthermore, kinesins were extensively studied in cancer research and therapeutic strategies targeting their specific functions, such as the example of monastrol and other inhibitors of the mitotic kinesins may be adopted in the future.
There are likely many more kinesinopathies to be unravelled in the field of birth defects because of buy levitra online their pivotal role in cellular logistics, but their recognition in clinics and research will depend on our ability to identify and characterise the common clinical, molecular and functional themes of these disorders and to use them to improve our understanding of their disease mechanisms.IntroductionIntellectual disability (ID) affects about 3% of individuals worldwide and raises significant issues in terms of diagnostic, management and genetic counselling. The presence of pigmentation anomalies in a patient with ID represents helpful clinical clues in order to narrow the range of aetiological hypothesis. Hypomelanosis of Ito (HMI, MIM #300337) is an unspecific term encompassing a heterogeneous group of disorders characterised buy levitra online by cutaneous hypopigmented whorls and streaks along Blaschkoâs lines and variable extracutaneous features affecting the musculoskeletal and nervous systems.1 The cutaneous pattern therefore represents a non-specific hallmark of mosaicism in these neurocutaneous conditions.
Genetic mosaicism is due to postzygotic mutations, either chromosomal rearrangements or point mutations, whereas random X inactivation in females leads to functional mosaicism.2 Unravelling the molecular basis of pigmentary mosaicism (PM) is still a challenge due to clinical and genetic heterogeneity, technical difficulties in detecting mosaic mutations by classical sequencing approaches and the complexities of obtaining affected tissue. As part of a collaborative group, we recently reported de novo mutations in exons 3 and 4 of transcription factor E3 (TFE3) as the cause for HMI in four unrelated individuals, including one male, buy levitra online as well as syndromic ID without pigmentary disorders in a female.3TFE3 belongs to the MITF family of mammalian basic helixâloopâhelix zipper transcription factors, together with TFEB and TFEC. All four can form homodimers or heterodimers with each other.4 Embryonic expression of TFE3 orthologues Tfe3a and Tfe3b was demonstrated in the zebrafish in a wide range of tissues.5 TFE3 subcellular localisation plays a crucial role in the regulation of cellular homeostasis and embryonic stem cell (ESC) differentiation.
The phosphorylated TFE3 is retained in the cytoplasm, whereas dephosphorylated protein translocates to the nucleus to promote the transcription of target genes involved in lysosomal biogenesis and autophagy.6 TFE3 relocalisation to the nucleus is driven on various stressors, such as starvation,7 8 DNA damage,9 mitochondrial damage,10 Golgi stress11 and pathogens12 in an mTORC1-dependent manner, and oxidative stress13 or cadmium exposition14 in an mTORC1-independent manner. Moreover, lysosomal signalling-induced nucleocytoplasmic redistribution of TFE3 is essential to the regulation of ESC renewal.3 15 By restricting nuclear localisation and activity of Tfe3, lysosome activity, the tumour suppressor protein folliculin and the Ragulator protein complex enable buy levitra online the exit from pluripotency and therefore drive differentiation. Conversely, enforced nuclear Tfe3 enables ESCs to withstand differentiation.15 In humans, TFE3 mutations have long been known in cancer.
Gene fusions by translocations or other chromosomal rearragements involving TFE3 and five partner genes have indeed been reported to occur in a subset of renal cell carcinomas (RCCs), referred to as âTFE-fusion RCCâ, and, more rarely, to lung sarcoma and perivascular epithelioid cell tumours.16 Beyond these data on TFE3 function, by the report of a series of 17 individuals harbouring de novo mutations in exons 3 and 4 of TFE3, we emphasise their phenotype and bring additional clinical insight toward the recognition of this novel developmental disorder.ResultsWe describe a series of 17 buy levitra online patients carrying a de novo mutation in TFE3, 5 of them being previously published with limited clinical information.3 Twelve were females and five were males. Their age ranged from 12 months to 22 years. Five were referred for HMI, five for syndromic ID and five for suspicion of storage disorder.Clinical dataThe clinical buy levitra online features are summarised in table 1.
Additional information can be found in online supplementary data 1.Supplemental materialView this table:Table 1 Clinical and molecular features of the 17 patients with an TFE3 mutationNeonatal course was remarkable for nine patients. History of jaundice, hepatomegaly or feeding difficulties was reported for three patients each, hypoglycaemia for two and cholestasis for one. All these features were transient.Developmental delay, usually severe and noticeable from the buy levitra online first months of life, was a constant feature in all the individuals.
Only 6 patients were able to walk at the time of the study, whereas 11 were still unable to walk. All patients were non-verbal, except for two older patients who could speak a few buy levitra online words. Neurological examination was abnormal in 12 individuals and consisted in truncal hypotonia, associated with lower limb spasticity (6 individuals) or ataxia (2 adults).
Behavioural issues such as autistic buy levitra online features and sleeping disturbance were noted for 11 patients. Eleven patients developed epilepsy, onset in the first decade and characterised as intractable in three of them. Brain MRI was normal in 10 individuals and abnormal in 6 patients (hydrocephaly, short corpus callosum, Dandy-Walker malformation, arachnoid cyst, periventricular white matter lesions, delayed myelination and cerebral atrophy).
The sensory anomaly buy levitra online was congenital hearing loss (5 patients), and ophtalmological anomalies (10 patients) consisted of strabismus, hyperopia, retinal degeneration, depigmented macule on the iris, oculomotor apraxia or impaired vision of cortical origin.Facial dysmorphism shared among the patients consisted in coarseness, flat nasal bridge, short nose with anteverted nares, widely spaced eyes, almond-shaped eyes, thick lips, facial hypertrichosis, fleshy earlobe, and full and pink cheeks (figure 1). Twelve patients had pigmentation anomalies, located on Blaschkoâs lines for 10 of them (figure 2). One was diagnosed at 4 buy levitra online years old with histiocytofibroma.
Moderate to severe postnatal growth retardation affected 10 patients, who had a length between â2.0 and â4.5 SD. Obesity affected 13 buy levitra online individuals. Skeletal anomalies were frequent (11 individuals) and consisted of flat or clubfeet, hyperlordosis, scoliosis, hip dislocation, limitation of elbow extension and genu valgum.
Recurrent s of the upper airways were noted in five patients buy levitra online. One had a documented neutropenia. Early-onset chronic interstitial lung disease was reported in two patients.
Nail clubbing was noted in buy levitra online two individuals. Visceral malformations consisted of congenital heart defect (left ventricle dilatation, aortic insufficiency and patent ductus arteriosus) in three patients, umbilical hernia in three individuals, lateral semicircular canal dysplasia, posterior plagiocephaly, sleep apnoea syndrome, anteriorly displaced anus and hypospadias in one individual each.Facial phenotypes of seven patients.

This mutation was reported a few weeks ago in a patient with a similar phenotype.21 Two variants were localised in exon 3 and 11 in exon 4 (figure 3). All were absent from public databases and were predicted to be pathogenic by prediction softwares. TFE3 protein and localisation of the missense variants identified.

Characteristics, inheritance, frequency in the public database GnomAD, prediction scores regarding pathogenicity (Polyphen, Grantham and CADD (Combined Annotation Dependant Depletion) scores). The transcript is NM_006521.5The putative mosaicism was assessed through X inactivation studies in females and analysis of the exome sequencing data in males, by checking the total number of reads covering the variant, as well as the number of reads supporting the presence of the variant (table 1). Allele frequencies in females were always consistent with a constitutional heterozygous mutation.
X inactivation was skewed in blood of the female patients 1, 3 and 7 and in fibroblasts of Patient 2. X inactivation was random in fibroblasts of Patient 1 and 3. Regarding the male patients, the mutation was identified in 65% of the reads for Patient 17% and 88% of the reads for Patient 15 (106/120).
No mosaicism was detected in the blood of Patient 13, 14 and 16 despite the presence of pigmentary manifestations in Patient 16.DiscussionTFE3 functions in signalling of the mechanistic target of rapamycin (mTOR) complex 1 (mTORC1). The PIK3-AKT-mTOR pathway plays a role in the regulation of cellular growth, proliferation, survival and metabolism. Overactivation of the mTOR signalling is responsible for neurocutaneous disorders and cancers.22 Somatic mutations in TSC1, TSC2, AKT3, PIK3CA and MTOR are responsible for focal cortical dysplasia type II (MIM607341),23â25 hemimegalencephaly26 and megalencephaly.27 The phenotype ascribed to germline TSC1/TSC2, PTEN, MTOR and PK3R2/AKT3/CCND2 mutations â respectively in tuberous sclerosis (TS, MIM 191100), Cowden syndrome (CS, MIM 158350), Smith-Kingsmore syndrome (MIM 616638) and Megalencephaly, Polymicrogyria, Polydactyly and Hydrocephalus syndrome 1, 2 and 3 (MPPH1/2/3, MIM 603387/615939/615938) - is characterised by the association of ID, epilepsy, brain malformations and skin tumours.
Similarly, all the individuals harbouring a de novo TFE3 mutation reported in the series presented with a severe neurodevelopmental disorder. Delayed psychomotor development was constant. The youngest patient to acquire independent walking was 30 months old, and more than half of the patients aged over 18 months (57%), did not acquire walk at the last examination.
Conversely to patients with MTOR, AKT3 or PTEN mutation, none of the patients described in this series had macrocephaly. Brain imaging was abnormal in 35% of the patients. Hydrocephaly and corpus callosum dysgenesis, identified in respectively three and one individual, were previously reported in patients with mosaic gain of function MTOR mutations.28 29 One patient had surgery to remove an early-onset histiocytofibroma.
However, no other skin tumour was reported, either in this patient or in any other from the series.Pigmentation anomalies, along Blaschkoâs lines or, for one patient, as a large hyperpigmented area, were present in a majority of the individuals (71%) in the series, including 40% of the males and 83% of the females. PM along Blaschkoâs lines is highly suggestive of genetic mosaicism.30 Genomic mosaicism is defined by the presence of at least two cell populations with different genotypes in an individual originating from one zygote and mainly occurs through post-zygotic event, whereas females can present with functional (epigenetics) mosaicism due to X inactivation.2 PM is a classical feature of X-linked male-lethal genodermatosis, such as incontinentia pigmenti (IP, MIM #308300), focal dermal hypoplasia (FDH, MIM #305600), chondrodysplasia punctuata type 2 (Conradi-Hunermann-Happle syndrome, CDPX2, MIM #302960) and linear skin defects with multiple congenital anomalies (LSDMCA1, MIM #309801). In these conditions, the overwhelming predominance of affected females is a consequence of the male lethality, and the PM a manifestation of the functional mosaicism occurring in females.
Similarly, the majority of individuals with de novo TFE3 variants in our cohort were females (sex ratio female:male was 12:5 (2.4)). The study of X-inactivation on non-cultured fibroblasts was consistent with functional mosaicism in two affected females with PM who harboured random X-inactivation, whereas a third female without PM had skewed X-inactivation. In IP, FDH and CDPX2, most hemizygous males die in utero.
However, there have been reports of surviving males 31â33 with an estimated prevalence around 10% in FDH and IP.32 34 The majority of them are explained by post-zygotic mutations or chromosomal anomalies (Klinefelter syndrome). Non-mosaic males have also been reported in FDH and IP â respectively about 17% and 45% of the affected males harbour a non-mosaic variant.32 35 In our series, males represented 29% of the patients with a de novo TFE3 variant. A mosaic variant was identified in blood for half of them.
None had Klinefelter syndrome. Interestingly, mosaicism was detected in only one out of the two males with PM, and one male with a mosaic variant had no pigmentation anomalies noted on examination. It is still possible that subtle pigmentation anomalies were missed on examination.
Moreover, somatic mosaicism can be difficult to detect. Recent studies have shown that a large proportion of de novo mutations presumed to be germline had in fact occurred as post-zygotic event.36 In the males of this cohort, WES was performed on leucocytes-derived DNA and no other tissue was studied. Therefore, it is possible that a low mosaicism was not detected.
Finally, it is probable than TFE3 mutations account for a significant proportion of patients with HMI. Indeed, in this population, the high frequency of ID, epilepsy, coarse facial features has long been emphasised in the literature.37By its ability to bind the coordinated lysosomal enhancement and regulation (CLEAR) sites in the promotor region of target genes, TFE3 is involved in the control lysosomal biogenesis, autophagy and endocytosis.8 Several patients of the series indeed had clinical and biochemical features that pointed toward an inborn error of metabolism. Lysosomal storage disorder was suspected due to the variable association of coarse facial features (88%), skeletal anomalies (65%) âflat or clubfeet, hyperlordosis, hip dislocation, limitation of elbow extension, genu valgum, scoliosisâ, postnatal growth retardation (59%), history of speech or developmental regression (29%) congenital hearing loss (29%), recurrent upper airways s (29%) neonatal liver anomalies such as hepatomegaly and cholestasis (18%), upper airways s (24%), umbilical hernia (18%), sleep apnoea syndrome (6%) and aortic insufficiency (6%).
Other metabolic anomalies observed in the series were obesity, defined in children by body mass index (BMI) (weight/height2) above the WHO curve, present in the oldest patients (76%), neonatal transient hypoglycaemia (12%), and hyperlactataemia (6%). Dysregulation of lipid metabolism, via suppression of thermogenesis and decreased lipolysis, thus leading to increased adipose tissue, was previously observed in adipose-specific TFE3 transgenic mice.38 Similarly to lysosomes, mitochondrias have a key role in cellular metabolism, including autophagy. Recent data demonstrate that mitochondrial and lysosomal metabolisms are interrelated.39 Muscle biopsy, performed in two individuals from this cohort, showed fat and glycogen accumulation, muscular fibre size irregularity, without evidence of mitochondrial dysfunction.
Interestingly in the more recent data, evidences showing that TFE3 plays a role in the regulation of the circadian oscillations of the expression of genes involved in autophagy and lipid metabolism, and that Tfe3 knock-out mice had abnormal circadian behaviour.40 Indeed, in our series, five patients (29%) were noted to have sleep disturbance. This could be due to circadian rhythms alteration. Finally, TFE3 has been shown to be involved in the regulation of innate immune response in macrophages via the FLCN-AMPK signalling axis,41 and of B-lymphocytes activation.42 Along these lines, four patients of the series (24%) had a history of recurrent s, associated with documented neutropenia in one of them.
As shown in table 3, a summary of the frequency of the features observed in the cohort, facial dysmorphism was constant and strikingly similar among the patients. More than two-third had anteverted nares, broad flat nasal bridge, almond-shaped and widely spaced eyes, puffy cheeks and coarse facial features (thick lips and fleshy earlobes). More than half had facial hypertrichosis.
All individuals presented with at least four of the above features. One patient had an extreme facial phenotype of hypertelorism, bifid nose and bilateral cleft lip and palate. Whether these frontonasal dysplasia features may be associated with the TFE3 mutation remains unclear.
No other mutation in known genes was found in Patient 1âs exome sequencing data.View this table:Table 3 Frequency of the clinical features observed in the seriesTFE3 is a highly conserved protein, intolerant to loss of function as supported by data from the GnomAD browser43 (probability of being loss-of-function intolerant (pLI) evaluated at 0.98, observed:expected ratio=0.06) and to missense variants (Z=2.15). Moreover, TFE3 does not, or only in a few tissues, escape X inactivation, suggesting that TFE3 gene dosage is crucial to cell function.44 45 In vitro, Villegas et al recently showed that the absence of either TFE3 exon 3 or 4 resulted in a nuclear gain-of-function Tfe3 allele in ESCs, indicating that both exons 3 and 4 are required for Tfe3 inactivation.3 Nuclear localisation and resistance to differentiation were proved in Tfe3 knock-out (K.O.) ESCs expressing murine Tfe3 alleles (Gln118Pro and Pro185Leu, corresponding to mutations Gln119Pro and Pro186Leu identified in individuals referred to as patients 1 and 2 in this series). Based on the analysis of TFE3 secondary structure,46 indicating that residues 110â215 are predicted to form a domain of two stable alpha helices that might be disrupted by mutations in exons 3 and 4, and the observation of a similar phenotype in patients harbouring mutations in exons 3 and 4, it was suggested that Tfe3 exons 3 and 4 form a Rag binding fold whose structural integrity is indispensable for lysosome-mediated cytoplasmic Tfe3 inactivation.3 In this series, the recurrent mutations Arg117Gln, Leu191Pro and Thr187Met were present in respectively two, two and three patients.
The aminoacid in position 187 was mutated in five patients. In addition, 13 of the described mutations were localised between positions p.184 and p.201. This proximity could account for the absence of obvious genotypeâphenotype correlation.
The canonical splice site variant in intron 4 identified in patient 9 might lead to in-frame exon skipping of exon 4. The clinical picture of the patient with this splice site variant perfectly fits with the syndrome described here. As a consequence, we raise the hypothesis of a gain-of-function effect of this variant.In conclusion, de novo mutations in exons 3 and 4 of the X-linked gene TFE3 are responsible for a neurocutaneous disorder with specific and recognisable facial dysmorphism, lysosomal storage disorder-like features and PM.
This series unravels TFE3 as a major gene responsible for HMI and for a rare cause of syndromic ID. Furthermore, we provide clinical and molecular data on a previously unidentified lysosomal storage disorder, in which new insights, especially biochemical features, will probably be investigated further, together with the description of more patients. Further delineation of this phenotype will indeed allow a better understanding of the link between lysosomal signalling and development.
Finally, the evidence for mosaicism in this recently described disorder highlights the importance of considering mosaic variants on next-generation sequencing reports in diagnostic, including for patients without suggestive phenotype..

Indian J Psychiatry 2020;62:457-8erectile dysfunction treatment levitra is expected to bring a buy levitra discount Tsunami of mental health issues. Public health emergencies may affect the well-being, safety, and security of both individuals and communities, which lead to a range of emotional reactions, unhealthy behavior, and noncompliance, with public health directives (such as home confinement and vaccination) in people who contact the disease as well as in the general population.[1] Thus far, there has been an increased emphasis on psychosocial factors such as loneliness, effect of quarantine, uncertainty, vulnerability to erectile dysfunction treatment , economic factors, and career difficulties, which may lead to increased psychiatric morbidity.Time has now come to pay attention to the direct effect of the levitra on brain and psychiatric adverse symptoms, resulting from the treatment provided.
Viral s are buy levitra discount known to be associated with psychiatric disorders such as depression, bipolar disorder, obsessiveâcompulsive disorder (OCD), or schizophrenia. There was an increased incidence of psychiatric disorders following the Influenza levitra. Karl Menninger described 100 cases of influenza presenting buy levitra discount with psychiatric sequelae, which could mainly be categorized as dementia praecox, delirium, other psychoses, and unclassified subtypes. Dementia praecox constituted the largest number among all these cases.[2] Neuroinflammation is now known as the key factor in genesis and exacerbation of psychiatric disorders, particularly depression and bipolar disorders.Emerging evidence points toward the neurotropic properties of the erectile dysfunction levitra.
Loss of smell and taste as an initial symptom points toward early involvement buy levitra discount of olfactory bulb. The rapid spread to brain has been demonstrated through retrograde axonal transport.[3] The levitra can enter the brain through endothelial cells lining the bloodâbrain barrier and also through other nerves such as the vagus nerve.[4] Cytokine storm, a serious immune reaction to the levitra, can activate brain glial cells, leading to delirium, depression, bipolar disorder, and OCD.Studies examining psychiatric disorders in acute patients suffering from erectile dysfunction treatment found almost 40% of such patients suffering from anxiety, depression, and posttraumatic stress disorder.[5] The data on long-term psychiatric sequelae in patients who have recovered from acute illness are limited. There are anecdotal reports of psychosis and mania occurring in patients of erectile dysfunction treatment following discharge from hospital. This may be either due to the direct effect of the levitra on the brain or due to the buy levitra discount neuropsychiatric effects of drugs used to treat the or its complications.
For example, behavioral toxicity of high-dose corticosteroids which are frequently used during the treatment of severe cases to prevent and manage cytokine storm.The patients with erectile dysfunction treatment can present with many neuropsychiatric disorders, which may be caused by direct inflammation, central nervous system effects of cytokine storm, aberrant epigenetic modifications of stress-related genes, glial activation, or treatment emergent effects.[6] To assess and manage various neuropsychiatric complications of erectile dysfunction treatment, the psychiatric community at large should equip itself with appropriate assessment tools and management guidelines to effectively tackle this unprecedented wave of psychiatric ailments.

None, Conflict of Interest. NoneDOI. 10.4103/indianjpsychiatry.indianjpsychiatry_1169_2Abstract The erectile dysfunction treatment levitra has emerged as a major stressor of a global scale, affecting all aspects of our lives, and is likely to contribute to a surge of mental ill health. Ancient Hindu scriptures, notably the Bhagavad Gita, have a wealth of insights that can help approaches to build psychological resilience for individuals at risk, those affected, as well as for caregivers.
The path of knowledge (Jnana yoga) promotes accurate awareness of nature of the self, and can help reframe our thinking from an âIâ to a âwe mode,â much needed for collectively mitigating the spread of the erectile dysfunction. The path of action (Karma yoga) teaches the art of selfless action, providing caregivers and frontline health-care providers a framework to continue efforts in the face of uncertain consequences. Finally, the path of meditation (Raja yoga) offers a multipronged approach to healthy lifestyle and mindful meditation, which may improve resilience to the illness and its severe consequences. While more work is needed to empirically examine the potential value of each of these approaches in modern psychotherapy, the principles herein may already help individuals facing and providing care for the erectile dysfunction treatment levitra.Keywords.
Bhagavad Gita, erectile dysfunction treatment, YogaHow to cite this article:Keshavan MS. Building resilience in the erectile dysfunction treatment era. Three paths in the Bhagavad Gita. Indian J Psychiatry 2020;62:459-61The erectile dysfunction treatment crisis has changed our world in just a matter of months, thrusting us into danger, uncertainty, fear, and of course social isolation.
At the time of this writing, over 11 million individuals have been affected worldwide (India is fourth among all countries, 674,515) and over half a million people have died. The erectile dysfunction treatment levitra has been an unprecedented global stressor, not only because of the disease burden and mortality but also because of economic upheaval. The very fabric of the society is disrupted, affecting housing, personal relationships, travel, and all aspects of lifestyle. The overwhelmed health-care system is among the most major stressors, leading to a heightened sense of vulnerability.
No definitive treatments or treatment is on the horizon yet. Psychiatry has to brace up to an expected mental health crisis resulting from this global stressor, not only with regard to treating neuropsychiatric consequences but also with regard to developing preventive approaches and building resilience.Thankfully, there is a wealth of wisdom to help us in our ancient scriptures such as the Bhagavad Gita[1] for building psychological resilience. The Bhagavad Gita is a dialog between the Pandava prince Arjuna and his charioteer Krishna in the epic Mahabharata, the great tale of the Bharata Dynasty, authored by Sage Vyasa (c. 4â5 B.C.E.).
The dialog occurs in the 6th chapter of the epic and has over 700 verses. In this epic story, Arjuna, the righteous Pandava hero was faced with the dilemma of waging a war against his cousins, the Kauravas, for territory. Arjuna is confused and has no will to initiate the war. In this context, Krishna, his charioteer and spiritual mentor, counsels him.
The key principles of this spiritual discourse in the Gita are embodied in the broad concept of yoga, which literally means âYogâ or âto unite.â Applying three tenets of yoga can greatly help developing resilience at individual, group, and societal levels. A fourth path, Bhakti yoga, is a spiritual approach in the Gita which emphasizes loving devotion toward a higher power or principle, which may or may not involve a personal god. In this editorial, I focus on three paths that have considerable relevance to modern approaches to reliance-focused psychotherapy that may be especially relevant in the erectile dysfunction treatment era. Path of Knowledge The first concept in the Gita is the path of knowledge (Jnana Yoga, chapter 2).
The fundamental goal of Jnana yoga is to liberate oneself from the limited view of the individual ego, and to develop the awareness of one's self as part of a larger, universal self. Hindu philosophers were among the earliest to ask the question of âwho am Iâ and concluded that the self is not what it seems. The self as we all know is a collection of our physical, mental, and social attributes that we create for ourselves with input from our perceptions, and input by our families and society. Such a world view leads to a tendency to crave for the âIâ and for what is mine, and not consider the âWe.â As Krishna in the Bhagavad Gita points out, the person who sees oneself in others, and others in oneself, really âsees.â Such awareness, which guides action in service of self as well as others, is critically important in our goals of collectively preventing the spread of the erectile dysfunction.
A glaring example is the use of face masks, known to effectively slow the viral . Using the mask is as important to protecting oneself from the levitra as well as protecting others from oneself. Nations such as the USA (and their leaders), who have given mixed messages to the public about the need to wear masks, have been showing a strikingly high number of cases as well as mortality. Unfortunately, such reluctance to wear masks (and thus model protective hygiene for the population), as in the case of the US leader, has stemmed from ego or vanity-related issues (i.e., how he would appear to other leaders!.
). This factor may at least partly underlie the worse erectile dysfunction treatment outcome in the USA. The simple lesson here is that it is important to first flatten the ego if one wants to flatten the levitra curve!. Path of Action The second key concept is the path of action (Karma yoga, chapter 3).
Karma yoga is all about taking action without thinking, âwhat's in it for me.â As such, it seeks to mainly let go of one's ego. In the Bhagavad Gita, Arjuna is ambivalent about fighting because of the conflict regarding the outcome brought on by waging the war, i.e., having to kill some of his own kith and kin. Krishna reminds him that he should not hesitate, because it is his nature and duty (or Dharma), as a warrior, to protect the larger good, though it will have some downside consequences. The frontline health-care worker caring for severely ill patients with erectile dysfunction treatment is likely to have a similar emotional reaction as Arjuna, facing a lack of adequate treatments, high likelihood of mortality and of unpredictable negative outcomes, and risk to him/herself.
Compounding this, especially when resources such as ventilators are limited, the doctor may have to make tough decisions of whose life to save and whose not. Adding to this are personal emotions when facing with the death of patients, having to deliver bad news, and dealing with grieving relatives.[2] All these are likely to result in emotional anguish and guilt, leading to burnout and a war âneurosis.âSo, what should the frontline health-care provider should do?. Krishna's levitra price in usa counsel would be that the doctor should continue to perform his/her own dharma, but do so without desire or attachment, thereby performing action in the spirit of Karma yoga. Such action would be with detachment, without a desire for personal gain and being unperturbed by success or failure.
Such âNishkaama Karmaâ (or selfless action) may help doctors working today in the erectile dysfunction treatment outbreak to carry forward their work with compassion, and accept the results of their actions with equanimity and without guilt. Krishna points out that training one's mind to engage in selfless action is not easy but requires practice (Abhyasa). Krishna is also emphatic about the need to protect oneself, in order to be able to effectively carry out one's duties. Path of Meditation The third core concept in the Gita is the path of meditation and self-reflection (Raja yoga, or Dhyana yoga, chapter 6).
It is considered the royal path (Raja means royal) for attaining self-realization, and often considered the 8-fold path of yoga (Ashtanga yoga) designed to discipline lifestyle, the body and mind toward realizing mindfulness and self-reflection. These techniques, which originated in India over two millennia ago, have evolved over recent decades and anticipate several approaches to contemplative psychotherapy, including dialectical behavior therapy, acceptance and commitment therapy, and mindfulness-based stress reduction.[3] These approaches are of particular relevance for stress reduction and resilience building in individuals faced by erectile dysfunction treatment-related emotional difficulties as well as health-care providers.[4]The majority of people affected by the erectile dysfunction treatment levitra recover, but about 20% have severe disease, and the mortality is around 5%. Older individuals, those with obesity and comorbid medical illnesses such as diabetes and lung disease, are particularly prone to developing severe disease. It is possible that a state of chronic low-grade inflammation which underlies each of these conditions may increase the risk of disproportionate host immune reactions (with excessive release of cytokines), characterizing severe disease in those with erectile dysfunction treatment.[4] With this in mind, it is important to note that exercise, some forms of meditation, anti-inflammatory and antioxidant diet (such as turmeric and melatonin), and yoga have known benefits in reducing inflammation.[5],[6],[7],[8],[9] Sleep loss also elevates inflammatory cytokines.
Healthy sleep may reduce inflammation.[10] Clearly, a healthy lifestyle, including healthy sleep, exercise, and diet, may be protective against developing erectile dysfunction treatment-related severe complications. These principles of healthy living are beautifully summarized in the Bhagavad Gita.Yuktahara-viharasya yukta-cestasya karmasuYukta-svapnavabodhasya yogo bhavati duhkha-haHe who is temperate in his habits of eating, sleeping, working and recreation can mitigate all sorrows by practicing the yoga system.âBhagavad Gita, Chapter 6, verse 17.The relevance of the Bhagavad Gita for modern psychotherapy has been widely reviewed.[11],[12] However, relatively little empirical literature exists on the effectiveness of versus spiritually integrated psychotherapy incorporating Hindu psychotherapeutic insights. Clearly, more work is needed, and erectile dysfunction treatment may provide an opportunity for conducting further empirical research.[13] In the meantime, using the principles outlined here may already be of benefit in helping those in need, and may be rapidly enabled in the emerging era of telehealth and digital health.[14]Financial support and sponsorshipNil.Conflicts of interestThere are no conflicts of interest.

More than 90% of https://en.cubcadet.eu/where-to-get-levitra-pills/ babies born with heart defects survive into adulthood buy levitra from canada. As a buy levitra from canada result, there are now more adults living with congenital heart disease than children. These adults have a chronic, lifelong condition and the European Society of Cardiology (ESC) has produced advice to give the best chance of a normal life. The guidelines are published online today in European Heart Journal,1 and on buy levitra from canada the ESC website.2Congenital heart disease refers to any structural defect of the heart and/or great vessels (those directly connected to the heart) present at birth. Congenital heart disease affects all aspects of life, including physical and mental health, socialising, and work.
Most patients are unable to exercise at the same level as their peers which, along with the awareness of having a chronic condition, affects mental wellbeing."Having a congenital heart disease, with a need for buy levitra from canada long-term follow-up and treatment, can also have an impact on social life, limit employment options and make it difficult to get insurance," said Professor Helmut Baumgartner, Chairperson of the guidelines Task Force and head of Adult Congenital and Valvular Heart Disease at the University Hospital of Münster, Germany. "Guiding and supporting patients in all of these processes is an inherent part of their care."All adults with congenital heart disease should have at least one appointment at a specialist centre to determine how often they need to be seen. Teams at these centres should buy levitra from canada include specialist nurses, psychologists and social workers given that anxiety and depression are common concerns.Pregnancy is contraindicated in women with certain conditions such high blood pressure in the arteries of the lungs. "Pre-conception counselling is recommended for women and men to discuss the risk of the defect in offspring and the option of foetal screening," said Professor Julie De Backer, Chairperson of the guidelines Task Force and cardiologist and clinical geneticist at Ghent University Hospital, Belgium.Concerning sports, recommendations are provided for each condition. Professor De buy levitra from canada Backer said.
"All adults with congenital heart disease should be encouraged to exercise, taking into account the nature of the underlying defect and their own abilities."The guidelines state when and how to diagnose complications. This includes proactively monitoring for arrhythmias, cardiac imaging buy levitra from canada and blood tests to detect problems with heart function.Detailed recommendations are provided on how and when to treat complications. Arrhythmias are an important cause of sickness and death and the guidelines stress the importance of correct and timely referral to a specialised treatment centre. They also list when particular treatments should be considered buy levitra from canada such as ablation (a procedure to destroy heart tissue and stop faulty electrical signals) and device implantation.For several defects, there are new recommendations for catheter-based treatment. "Catheter-based treatment should be performed by specialists in adult congenital heart disease working within a multidisciplinary team," said Professor Baumgartner.

Content may be edited for style and length.One in five patients die within a year after the most common type of heart attack. European Society of Cardiology (ESC) treatment guidelines for non-ST-segment elevation acute coronary syndrome are published online today in European Heart Journal, and on the ESC website.Chest pain is the most common symptom, along with pain radiating to one or both arms, the neck, or jaw.
Anyone experiencing these symptoms should call an ambulance immediately. Complications include potentially deadly heart rhythm disorders (arrhythmias), which are another reason to seek urgent medical help.Treatment is aimed at the underlying cause. The main reason is fatty deposits (atherosclerosis) that become surrounded by a blood clot, narrowing the arteries supplying blood to the heart. In these cases, patients should receive blood thinners and stents to restore blood flow. For the first time, the guidelines recommend imaging to identify other causes such as a tear in a blood vessel leading to the heart.Regarding diagnosis, there is no distinguishing change on the electrocardiogram (ECG), which may be normal.
The key step is measuring a chemical in the blood called troponin. When blood flow to the heart is decreased or blocked, heart cells die, and troponin levels rise. If levels are normal, the measurement should be repeated one hour later to rule out the diagnosis. If elevated, hospital admission is recommended to further evaluate the severity of the disease and decide the treatment strategy.Given that the main cause is related to atherosclerosis, there is a high risk of recurrence, which can also be deadly. Patients should be prescribed blood thinners and lipid lowering therapies.
"Equally important is a healthy lifestyle including smoking cessation, exercise, and a diet emphasising vegetables, fruits and whole grains while limiting saturated fat and alcohol," said Professor Jean-Philippe Collet, Chairperson of the guidelines Task Force and professor of cardiology, Sorbonne University, Paris, France.Behavioural change and adherence to medication are best achieved when patients are supported by a multidisciplinary team including cardiologists, general practitioners, nurses, dietitians, physiotherapists, psychologists, and pharmacists.The likelihood of triggering another heart attack during sexual activity is low for most patients, and regular exercise decreases this risk. Healthcare providers should ask patients about sexual activity and offer advice and counselling.Annual influenza vaccination is recommended -- especially for patients aged 65 and over -- to prevent further heart attacks and increase longevity."Women should receive equal access to care, a prompt diagnosis, and treatments at the same rate and intensity as men," said Professor Holger Thiele, Chairperson of the guidelines Task Force and medical director, Department of Internal Medicine/Cardiology, Heart Centre Leipzig, Germany.

New research suggests that a good night of sleep may be just what you need.This program of research comprised an analysis of diaries and lab experiments. The researchers analyzed daily diary entries from 202 college students, who tracked their sleep, daily stressors, and anger over one month. Preliminary results show that individuals reported experiencing more anger on days following less sleep than usual for them.The research team also conducted a lab experiment involving 147 community residents. Participants were randomly assigned either to maintain their regular sleep schedule or to restrict their sleep at home by about five hours across two nights.
Following this manipulation, anger was assessed during exposure to irritating noise.The experiment found that well-slept individuals adapted to noise and reported less anger after two days. In contrast, sleep-restricted individuals exhibited higher and increased anger in response to aversive noise, suggesting that losing sleep undermined emotional adaptation to frustrating circumstance. Subjective sleepiness accounted for most of the experimental effect of sleep loss on anger. A related experiment in which individuals reported anger following an online competitive game found similar results."The results are important because they provide strong causal evidence that sleep restriction increases anger and increases frustration over time," said Zlatan Krizan, who has a doctorate in personality and social psychology and is a professor of psychology at Iowa State University in Ames, Iowa. "Moreover, the results from the daily diary study suggest such effects translate to everyday life, as young adults reported more anger in the afternoon on days they slept less."The authors noted that the findings highlight the importance of considering specific emotional reactions such as anger and their regulation in the context of sleep disruption.

Overall, participants used fewer substances in the months after working with the hospital-based addictions team than before.The study published in the Journal of Substance Abuse Treatment."We found that polysubstance use is the norm," said lead author Caroline King, M.P.H., a health systems researcher and current M.D./Ph.D. Student in the OHSU School of Medicine's biomedical engineering program. "This is important because we may need to offer additional support to patients using multiple drugs. If someone with opioid use disorder also uses alcohol or methamphetamines, we miss caring for the whole person by focusing only on their opioid use."About 40% of participants reported they had abstained from using at least one substance at least a month after discharge -- a measure of success that isn't typically tracked in health system record-keeping.Researchers enrolled 486 people seen by an addiction medicine consult service while hospitalized at OHSU Hospital between 2015 and 2018, surveying them early during their stay in the hospital and then again 30 to 90 days after discharge. advertisement Treatment of opioid use disorder can involve medication such as buprenorphine, or Suboxone, which normalizes brain function by acting on the same target in the brain as prescription opioids or heroin.However, focusing only on the opioid addiction may not adequately address the complexity of each patient."Methamphetamine use in many parts of the U.S., including Oregon, is prominent right now," said senior author Honora Englander, M.D., associate professor of medicine (hospital medicine) in the OHSU School of Medicine.
"If people are using stimulants and opioids -- and we only talk about their opioid use -- there are independent harms from stimulant use combined with opioids. People may be using methamphetamines for different reasons than they use opioids."Englander leads the in-hospital addiction service, known as Project IMPACT, or Improving Addiction Care Team.The initiative brings together physicians, social workers, peer-recovery mentors and community addiction providers to address addiction when patients are admitted to the hospital. Since its inception in 2015, the program has served more than 1,950 people hospitalized at OHSU.The national opioid epidemic spiraled out of control following widespread prescribing of powerful pain medications beginning in the 1990s. Since then, it has often been viewed as a public health crisis afflicting rural, suburban and affluent communities that are largely white.Englander said the new study suggests that a singular focus on opioids may cause clinicians to overlook complexity of issues facing many populations, including people of color, who may also use other substances."Centering on opioids centers on whiteness," Englander said. "Understanding the complexity of people's substance use patterns is really important to honoring their experience and developing systems that support their needs."Researchers say the finding further reinforces earlier research showing that hospitalization is an important time to offer treatment to people with substance use disorder, even if they are not seeking treatment for addiction when they come to the hospital.
