Autosomal recessive missense Rotatin (RTTN) mutations are responsible for syndromic forms of malformation of cortical development, ranging from isolated polymicrogyria to microcephaly associated with primordial dwarfism and other major malformations. We identified, by trio based whole exome sequencing, a homozygous missense mutation in the RTTN gene (c.2953A > G; p.(Arg985Gly)) in one Moroccan patient from a consanguineous family. The patient showed early onset primary microcephaly, detected in the fetal period, postnatal growth restriction, encephalopathy with hyperkinetic movement disorders and self-injurious behavior with sleep disturbance...

Stress, drug use, and depression are interconnected, but less is understood about sources of stress among adults with co-occurring drug use and depressive symptoms. The current study aimed to identify sources of stress and correlates among these adults. Data come from a cross-sectional baseline survey, including participants (n = 336) 18 to 55 years old, who reported past 6-month heroin or cocaine use and depressive symptoms. Exploratory factor analysis was conducted to identify sources of stress. Chi-square and multivariable Poisson regression with robust error variance were used to explore correlates of each factor...

PURPOSE OF REVIEW: To provide an overview of the mechanistic and epidemiologic evidence linking sleep-related exposures, such as short sleep duration, obstructive sleep apnea, shift work, and insomnia, with type 2 diabetes risk in adults. RECENT FINDINGS: Both poor sleep habits and sleep disorders are highly prevalent among adults with type 2 diabetes. In observational studies, short sleep duration, obstructive sleep apnea, shift work, and insomnia are all associated with higher risk of incident type 2 diabetes and may predict worse outcomes in those with existing diabetes...

INTRODUCTION: Glucocerebrosidase (GBA) mutations and leucine-rich repeat kinase 2 (LRRK2) variants are the most common genetic risk factors for late-onset Parkinson's disease (PD). In this study, we aimed to investigate the differences in pre-diagnostic symptoms of PD associated with the variants. METHODS: The participants were recruited from 24 centers across China and genotyped for LRRK2 G2385R and R1628P variants and GBA L444P mutation. Participants were surveyed with structural questionnaires for history of environmental exposure and living habits and interviewed to collect the time at onset of each symptoms before diagnosis...

BACKGROUND: Somatoform Disorders (SD) are a heterogeneous group of psychiatric syndromes characterized by common symptoms, which may mimic a physical condition but they are not explained by a medical condition. Although the biologic nature of this disorder has been widely accepted, the neuroanatomical correlates characterizing SD are still inconclusive. Therefore, this study aims to explore gray matter (GM) volume alterations in SD patients compared to healthy controls and their possible association with clinical and cognitive measures...

BACKGROUND: Niemann-Pick disease type C (NPC) is a lysosomal storage disorder with severe prognosis. Disease-specific therapy is crucial to prevent disease progression; however, diagnosing NPC is quite difficult because of remarkably variable clinical presentations. The NPC Suspicion Index (NPC-SI) was developed to overcome this problem. Identifying preclinical cases is important for prevention and therapy. Here, we report three newly diagnosed NPC cases, one typical juvenile-onset case and the cases of two sisters with symptoms neurologically/psychiatrically indistinguishable from dystonia and schizophrenia, respectively...

BACKGROUND: Kidney stone (KS) disease has high, increasing prevalence in the United States and poses a massive economic burden. Diagnostics algorithms of KS only use a few variables with a limited sensitivity and specificity. In this study, we tested a big data approach to infer and validate a 'multi-domain' personalized diagnostic acute care algorithm for KS (DACA-KS), merging demographic, vital signs, clinical, and laboratory information. METHODS: We utilized a large, single-center database of patients admitted to acute care units in a large tertiary care hospital...

Rapid eye movement (REM) sleep behavior disorder (RBD) is a parasomnia characterized by the presence of a complex of signals resulting from the loss of REM sleep atony and manifested by vigorous and sometimes violent motor jerks and nocturnal vocalizations associated with dream enactment. RBD might be a clinical predictor of severity for Parkinson's disease (PD) and one of its most important non-motor manifestations, preceding the emergence of synucleinopathy by several years or even decades. The detection of RBD may represent a therapeutic window for research regarding the development of new neuroprotective therapies with the potential to modify the natural course of synucleinopathies, such as PD...

OBJECTIVE: The present study investigated the association between previous deployment experience and somatic symptoms, mental health, unit climate perceptions, anger, and risk taking among junior-enlisted soldiers who were preparing to deploy or who were in garrison, or home duty station. The study also investigated potential differences in these variables based on unit leader deployment history. METHOD: Soldiers in a combat unit were surveyed either in a predeployment (n = 1,554; one week before deployment) or garrison setting (n = 1,326)...

Background: Posttraumatic Stress Disorder (PTSD) is associated with a number of negative physical and mental health consequences. Fear conditioning plays an important mechanistic role in PTSD, and PTSD patients also show deficits in safety signal learning. Sleep, particularly REM sleep, is linked to improved safety learning and extinction processes in animal models and healthy humans. No studies have examined the link between REM sleep and safety signal learning or extinction memory in clinical populations...

This study aimed to identify biomarkers of major depressive disorder (MDD), by relating neuroimage-derived measures to binary (MDD/control), ordinal (severe MDD/mild MDD/control), or continuous (depression severity) outcomes. To address MDD heterogeneity, factors (severity of psychic depression, motivation, anxiety, psychosis, and sleep disturbance) were also used as outcomes. A multisite, multimodal imaging (diffusion MRI [dMRI] and structural MRI [sMRI]) cohort (52 controls and 147 MDD patients) and several modeling techniques-penalized logistic regression, random forest, and support vector machine (SVM)-were used...

Jet lag is one of those common medical problems, to which most people don't give a serious thought. However, it is intricately intertwined with our normal circadian rhythm. It is classified as a sleep disorder. There is also a dearth of good scientific literature, not to mention clinical trials on the subject. Slowly but steadily, the scientific community is realizing the various deleterious health effects of jet lag and is devising innovative methods to counter them. This narrative review touches upon the etiopathogenesis, clinical manifestations and therapeutic strategies effective against the nagging problem of jet lag...

Restless Legs syndrome (RLS) is a common sleep disorder for which the genetic contribution remains poorly explained. In 2007, the first large scale genome wide association study (GWAS) identified three genomic regions associated with RLS. MEIS1, BTBD9 and MAP2K5/SKOR1 are the only known genes located within these loci and their association with RLS was subsequently confirmed in a number of follow up GWAS. Following this finding, our group reported the MEIS1 risk haplotype to be associated with its decreased expression at the mRNA and protein levels...

Parkinson's disease (PD) is a neurodegenerative disorder characterized by loss of dopaminergic neurons in the substantia nigra compacta (SNpc) and the only risk factor is aging. We showed that in 6-hydroxydopamine (6-OHDA)-model of PD there is a reduction in the neuronal profile within the brainstem ventral respiratory column with a decrease in the hypercapnic ventilatory response. Here we tested the involvement of orexin cells from the lateral hypothalamus/perifornical area (LH/PeF) on breathing in a 6-OHDA PD model...

The functions of sleep remain a mystery. Yet they must be important since sleep is highly conserved, and its chronic disruption is associated with various metabolic, psychiatric, and neurodegenerative disorders. This review will cover our evolving understanding of the mechanisms by which sleep is controlled and the complex relationship between sleep and disease states.

Objectives: Polysomnography is essential to diagnose sleep disorders. It is used to identify a patient's sleep pattern during sleep. This pattern is obtained by a doctor or health practitioner by using a scoring process, which is time consuming. To overcome this problem, we developed a system that can automatically classify sleep stages. Methods: This paper proposes a new method for sleep stage classification, called the fast convolutional method. The proposed method was evaluated against two sleep datasets...
