It has been hypothesized that disruption of circadian rhythms affects human health. Shift work and sleep deprivation are thought to disrupt the normal light-dark cycle, although the disruption due to shiftwork may be dependent on sleep deprivation. Both conditions have been suggested to be associated with an increased risk of cardiometabolic disorders. Non-photic environmental factors, such as the timing of eating, are also thought to regulate circadian rhythm and thus, may have effects on health, but the evidence from human studies is scarce...

Objective We here aimed at characterizing heart-brain interactions in patients with disorders of consciousness. We tested how this information impacts data-driven classification between unresponsive and minimally conscious patients. Methods A cohort of 127 patients in vegetative state/unresponsive wakefulness syndrome (VS/UWS, n=70) and minimally conscious state (MCS, n=57) were presented with the 'Local-Global' auditory oddball paradigm, which distinguishes two levels of processing: short-term deviation of local auditory regularities and global long-term rule violations...

BACKGROUND: Anorexia nervosa (AN) is a disabling, deadly and costly mental disorder. Until recently, treatment recommendations were based on expert opinion and limited evidence. The aim of this systematic review is to synthesise recent evidence on established and emerging AN treatments and to forecast trends for future developments. METHODS: We systematically review trials of established treatments and associated process outcome studies from the last 5 years, published since a previous review in this journal...

Duplication 15q syndrome (Dup15q) is an autism-associated disorder co-incident with high rates of pediatric epilepsy. Additional copies of the E3 ubiquitin ligase UBE3A are thought to cause Dup15q phenotypes, yet models overexpressing UBE3A in neurons have not recapitulated the epilepsy phenotype. We show that Drosophila endogenously expresses Dube3a (fly UBE3A homolog) in glial cells and neurons, prompting an investigation into the consequences of glial Dube3a overexpression. Here we expand on previous work showing that the Na(+)/K(+) pump ATPα is a direct ubiquitin ligase substrate of Dube3a...

Paramagnetic relaxation enhancement is an NMR technique that has yielded important insight into the structure of folded proteins, although the perturbation introduced by the large spin probe might be thought to diminish its usefulness when applied to characterizing the structural ensembles of intrinsically disordered proteins (IDPs). We compare the computationally generated structural ensembles of the IDP amyloid-β42 (Aβ42) to an alternative sequence in which a nitroxide spin label attached to cysteine has been introduced at its N-terminus...

Collapsing glomerulopathy (CGP) is a pattern of kidney injury seen on renal biopsy with multiple associations and etiologies. It is most commonly described in African-Americans and others with recent African ancestry. The disease is rapidly progressive and often presents with abrupt onset of renal failure and nephrotic-range proteinuria. Since its description 30 years ago, this entity has transformed from a morphologic diagnosis typically seen in the setting of HIV infection to a complicated diagnosis with numerous etiologies, many of which are associated with underlying apolipoprotein L1 (APOL1)-risk variants or other genetic disorders...

Shift work sleep disorder is a common problem in industrialized countries because of the need for occupations and services to continue to function 24 hours/day. Approximately 20% of employed adults in the United States are engaged in shift work. Shift work sleep disorder is diagnosed if there is a report of insomnia or excessive sleepiness for at least 3 months associated with a recurring work schedule that overlaps the usual time for sleep. Shift work is associated with an increased occurrence of metabolic disorders, such as insulin resistance, diabetes, dyslipidemia, and metabolic syndrome, and it has been implicated in weight gain and cognitive impairment...

The aim of this study was to explore the association between sleep-related problems with the occurrence of minor psychiatric disorders in shift workers of southern Brazil. A cross-sectional study with 1202 workers (785 females) aged 18-50 years was carried out. Minor psychiatric disorders were assessed using the Self-Reporting Questionnaire (SRQ-20), and four sleep problems were collected and analyzed: sleep deprivation (≤ 5h), difficulty falling asleep, waking up during sleep, and sleep medication use. Results show that the overall prevalence of minor psychiatric disorders was 26...

Intact optical information of an object delivered through an imaging system is deteriorated by imperfect optical elements and unwanted defects. Image deconvolution has been widely exploited as a recovery technique due to its practical feasibility, and operates by assuming linear shift-invariant property of the imaging system. However, shift invariance does not rigorously hold in all imaging situations and is not a necessary condition for solving an inverse problem of light propagation. Several improved deconvolution techniques exploiting spatially variant point spread functions have been proposed in previous studies...

BACKGROUND: Substance use is a well-established, and potentially modifiable, risk factor for suicide. Suicide prevention interventions are typically framed within the biomedical paradigm and focus on addressing individual risk factors, improving access to psychiatric care, and improving the skills of medical personnel to recognise at-risk individuals. Few studies have focused on contextual factors that hinder suicide prevention in people with substance use disorders, particularly in low-resource settings...

OBJECTIVES: Studies suggest that impairments in some of the same domains of cognition occur in different neuropsychiatric conditions, including those known to share genetic liability. Yet, direct, multi-disorder cognitive comparisons are limited, and it remains unclear whether overlapping deficits are due to comorbidity. We aimed to extend the literature by examining cognition across different neuropsychiatric conditions and addressing comorbidity. METHODS: Subjects were 486 youth consecutively referred for neuropsychiatric evaluation and enrolled in the Longitudinal Study of Genetic Influences on Cognition...

BACKGROUND: Mahamrutyunjaya rasa is an ayurvedic formulation used in the treatment of cardiac disorders. It contains the purified roots of Visa (Aconitum ferox), Brihati (Solanum indicum), fruits of Pippali Kana (Piper longum), Marica (Piper nigrum), Gandhaka (Sulfur), Hingula (Cinnabar) and Tankana (Sodium metaborate) as per Bhaishajya Ratnavali. The purification (shodhana) process changes the physiochemical properties of the raw materials which need to be studied and understood. OBJECTIVE: The present work aims to perform a comprehensive physicochemical characterization of raw materials, intermediates and the final product obtained during purification, using modern analytical techniques...

Damage to the temporal-parietal cortex in the right hemisphere often leads to spatial neglect-a disorder in which patients are unable to attend to sensory input from their contralesional (left) side. Neglect has been associated with both attentional and premotor deficits. That is, in addition to having difficulty with attending to the left side, patients are often slower to initiate leftward vs. rightward movements (i.e., directional hypokinesia). Previous research has indicated that a brief period of adaptation to rightward shifting prisms can reduce symptoms of neglect by adjusting the patient's movements leftward, toward the neglected field...

This study aimed to determine whether functional gastrointestinal disorders are more common among nurses with self-reported poor sleep. In total, 468 nurses working the day shift or rotating shifts completed two questionnaires: the questionnaire for irritable bowel syndrome (IBS) using Rome III criteria and the Pittsburgh Sleep Quality Index (PSQI). The prevalence of poor sleep was 41.04% (95% confidence interval, CI: [36.23, 45.85]), and poor sleep was significantly more common among rotating-shift nurses than among day-shift nurses (50...

"Sleep Medicine" is now a specialty in its own right. Currently, there is increasing recognition of the very negative impact sleep disorders have on learning, education, safety, and quality of life. Technological advances will help us to break down diagnoses (e.g., narcolepsy has now been subdivided into types 1 and 2, depending upon the hypocretin levels in the spinal fluid) and to discover relationships to other bodily systems (e.g., type 1 narcolepsy potentially being an autoimmune disorder). The modern lifestyle of many, as characterized by a shortening of sleep periods, shift work, jet lag, and the need to be constantly available, means that advances in sleep medicine may result in a major understanding of more balanced "work-rest lifestyle" modifications...

Work-related musculoskeletal disorders (WMSDs) persist as the leading occupational injury, accounting for nearly half of nurses' total occupational injuries. Musculoskeletal pain is a known cause of sleep disruption, and individuals with WMSDs that interfere with sleep often report more pain. Evening chronotype has been associated with poor sleep among nurses. However, the associations among chronotype, sleep, and WMSDs are still unclear, and were explored in the present study. A cross-sectional survey was administered to 397 nurses, with 47...

BACKGROUND: The mammalian circadian clock and its associated clock genes are increasingly been recognized as critical components for a number of physiological and disease processes that extend beyond hormone release, thermal regulation, and sleep-wake cycles. New evidence suggests that clinical behavior disruptions that involve prolonged shift work and even space travel may negatively impact circadian rhythm and lead to multi-system disease. METHODS: In light of the significant role circadian rhythm can hold over the body's normal physiology as well as disease processes, we examined and discussed the impact circadian rhythm and clock genes hold over lifespan, neurodegenerative disorders, and tumorigenesis...
