BACKGROUND: Prior studies have established that race and socioeconomic factors may influence weight loss after bariatric surgery. Few studies have focused on laparoscopic sleeve gastrectomy (LSG). The objective of this study is to determine if demographic factors may predict postoperative weight loss following LSG. METHODS: Prospectively collected data on 713 consecutive primary LSG operations performed with the same technique between February 2010 and May 2016 by a single surgeon (PG) were analyzed...

The goals of this paper were twofold: (a) To provide a population overview of burnout profiles by occupation in a large, health care sector employee population and (b) to investigate how burnout profiles relate to self-reported health behaviours, chronic conditions, and absenteeism. Burnout profiles were considered by 5 main occupational groups (physicians, nurses, other clinical, administrative, and wage grade [trade, craft, and labor workers]) in survey respondents (n = 86,257 employees). Logistic regression analyses were conducted to examine how burnout profiles were associated with health controlling for gender, age, race, ethnicity, and occupational group...

Observationally, higher caffeine consumption is associated with poorer sleep and insomnia. We investigated whether these associations are a result of shared genetic risk factors and/or (possibly bidirectional) causal effects. Summary-level data were available from genome-wide association studies on caffeine intake (n = 91 462), plasma caffeine and caffeine metabolic rate (n = 9876), sleep duration and chronotype (being a "morning" versus an "evening" person) (n = 128 266), and insomnia complaints (n = 113 006)...

Sleep deprivation in youth has garnered international attention in recent years, as correlational studies have demonstrated significant relationships between lack of sleep and detrimental behavioral and academic outcomes. However, no study to date has systematically examined the neurophysiological consequences of a single night of sleep restriction (i.e., 4 h) in adolescents using ultra-high field functional neuroimaging. Much of what we know regarding the neural consequences of sleep deprivation has come from the adult literature, and among those studies, the majority use region of interest (ROI) approaches, thus disregarding the dynamic mechanisms that may subserve the behavioral effects of sleep restriction...

INTRODUCTION: Many patients with opioid use disorder report symptoms similar to restless legs syndrome (RLS) during withdrawal. However, whether these symptoms are true RLS, their predictors and effect of treatment with pregabalin are still unknown. METHOD: A total of 19 consecutive patients with opioid use disorder who were admitted for detoxification were included in this study after obtaining informed consent. Information regarding addiction was noted, and they were screened for RLS every morning and evening...

OBJECTIVE: Familial dysautonomia (FD) is an autosomal recessive disorder characterized by impaired development of sensory and afferent autonomic nerves. Untreated sleep-disordered breathing (SDB) has been reported to increase the risk of sudden unexpected death in FD. We aimed to describe the prevalence and characteristics of SDB in FD. PATIENTS/METHODS: Seventy-five patients with FD (20 adults and 55 children) underwent in-lab polysomnography, including peripheral capillary oxygen saturation (SpO2 ) and end-tidal capnography (EtCO2 ) measurements...

INTRODUCTION: Delirium, which is prevalent in postcardiac surgical patients, is an acute brain dysfunction characterised by disturbances in attention, awareness and cognition not explained by a pre-existing neurocognitive disorder. The pathophysiology of delirium remains poorly understood. However, basic science and clinical studies suggest that sleep disturbance may be a modifiable risk factor for the development of delirium. Dexmedetomidine is a α-2A adrenergic receptor agonist medication that patterns the activity of various arousal nuclei similar to sleep...

Chronic insomnia is highly prevalent and associated with significant morbidity (i.e., confers risk for multiple psychiatric and medical disorders, such as depression and hypertension). Therefore, it is essential to identify factors that perpetuate this disorder. One candidate factor in the neurobiology of chronic insomnia is hypothalamic-pituitary-adrenal-axis dysregulation, and in particular, alterations in circadian cortisol rhythmicity. Cortisol secretory patterns, however, fluctuate with both a circadian and an ultradian rhythm (i...

KEY POINTS: Evidence at whole animal, organ-system, and cellular and molecular levels suggests that afferent volume feedback is critical for establishment of adequate ventilation at birth. Due to the irreversible nature of vagal ablation studies to date, it was difficult to quantify the roles of afferent volume input, arousal and changes in blood gas tensions on neonatal respiratory control. During reversible perineural vagal block, profound apneas, and hypoxemia and hypercarbia were observed necessitating termination of perineural blockade...

BACKGROUND: Patients with carpal tunnel syndrome often suffer from fragmentary sleep. This study was designed to assess the effectiveness of treatment with ultramicronized palmitoylethanolamide in reducing pain intensity and in improving quality of sleep in patients with neuropathic pain due to carpal tunnel syndrome. METHODS: An open, controlled study was conducted on 42 patients awaiting carpal tunnel syndrome surgery, suffering from sleep disorders and painful symptoms and randomized into two groups...

A sleep disorder is a medical disorder of the sleep pattern of a person that may be serious enough to interfere with normal physical, mental and emotional functioning. Disruptions in sleep can be caused by a variety of causes, from teeth grinding to night terrors. Sleep disorders are usually prevalent among adolescents and young adults, possibly due to factors related to life style, dietary habits, hormonal and emotional disturbances. Other factors that may precipitate sleep disorders include environmental, psychological and genetic factors...

The upper airway (UA) in humans is commonly modeled as a Starling resistor. However, negative effort dependence (NED) observed in some patients with obstructive sleep apnea (OSA) contradicts predictions based on the Starling resistor model in which inspiratory flow is independent of inspiratory driving pressure when flow is limited. In a respiratory bench model consisting of a collapsible tube and an active lung model (ASL5000), inspiratory flow characteristics were investigated in relation to upstream, downstream and extra-luminal pressures (denoted as Pus, Pds and Pout, respectively) by varying inspiratory effort (muscle pressure) from -1 to -20 cmH2 O in the active lung...

Although the gender gap in sleep time has narrowed significantly in the last decade, middle-aged women between ages 35 and 60 still sleep less than their male counterparts in Korea. This study examines and provides evidence for factors contributing to the gender gap in this age group. Using Korean Time Use Survey (KTUS) data from 2004, 2009 and 2014, we find that middle-aged women’s difficulty in managing work-life balance and traditional role expectations placed upon women are the main causes of the gender gap in sleep time...

BACKGROUND: The pathogenesis of type 2 diabetes (T2D) in black African women is complex and differs from that in their white counterparts. However, earlier studies have been cross-sectional and provide little insight into the causal pathways. Exercise training is consistently used as a model to examine the mechanisms underlying insulin resistance and risk for T2D. OBJECTIVE: The objective of the study was to examine the mechanisms underlying the changes in insulin sensitivity and secretion in response to a 12-week exercise intervention in obese black South African (SA) women...
