INTRODUCTION: Carbamate and organophosphate pesticides inhibit acetylcholinesterase, and poisoning leads to respiratory depression. Thus, involvement in sleep apnea is plausible, but no data exist at lower levels of exposure. Other pesticides could impact sleep apnea by different mechanisms but have not been studied. Our study examines the associations between pesticide exposure and sleep apnea among pesticide applicators from a US farming population. PARTICIPANTS AND METHODS: We analyzed data from 1569 male pesticide applicators, mostly farmers, from an asthma case-control study nested within the prospective Agricultural Health Study...

Parafunctional behaviors, especially bruxism, are not uncommon among patient visiting dentists' clinics daily and they constitute a major dental issue for almost all dentists. Many researchers have focused on the definition, pathophysiology, and treatment of these behaviors. These parafunctional behaviors have a considerable negative impact on teeth and dental prothesis. In this review, we focused on the impact of parafunctional behaviors on dental bridges. We summarized the definitions, epidemiology, pathophysiology, and consequences of parafunctional behaviors...

Epidemiological studies show a strong correlation between Obstructive Sleep Apnea (OSA) and cardiovascular disorders. OSA patients experience intermittent hypoxia (IH), characterized by brief, but recurring episodes of cessation in breathing. These patients have higher levels of circulating catecholamines and an increased incidence of hypertension; however the mechanisms defining this association are not clearly established. Genetic linkage studies have associated the phenylethanolamine N-methyltransferase (PNMT) gene to the development of hypertension...

BACKGROUND: Vagus nerve stimulation (VNS) can induce a sleep apnea syndrome (SAS), which in turn can worsen seizure control and represents a cardiovascular risk factor. Epidemiology of VNS-induced SAS has received little attention to date. The purpose of this study was to estimate the VNS-induced SAS prevalence and to explore clinical variables potentially correlating with its development. METHODS: We analyzed the computerized medical records of 18 consecutive adults treated for refractory epilepsy with VNS, implanted between May 2008 and October 2015...

Tamás Halmos, Ilona Suba
Non-alcoholic fatty liver disease is the most common non-infectious chronic liver-disease in our age, and is a spectrum of all the diseases associated with increased fat accumulation in the hepatocytes. Its development is promoted by sedentary life-style, over-feeding, and certain genetic predisposition. Prevalence in the adult population, even in Hungary is ~30%. In a part of cases, this disease may pass into non-alcoholic steatohepatitis, later into fibrosis, rarely into primary hepatocellular cancer. Fatty liver is closely and bidirectionally related to the metabolic syndrome and type 2 diabetes, and nowadays there is a general consensus that fatty liver is the hepatic manifestation of the metabolic sycndrome...

Michael Obladen
Since antiquity, cot death has been explained as accidental suffocation, overlaying, or smothering. Parents were blamed for neglect or drunkenness. A cage called arcuccio was invented around 1570 to protect the sleeping infant. Up to the 19th century, accidents were registered as natural causes of death. From 1830, accidental suffocation became unacceptable for physicians and legislators, and "natural" explanations for the catastrophe were sought, with parents being consoled rather than blamed. Two assumed causes had serious consequences: thymus hyperplasia was irradiated, causing thyroid cancer, and the concept of central apnea was widely accepted, which led to home monitors and distracted from epidemiological evidence...

REVIEW
Xiao Tan, Colin D Chapman, Jonathan Cedernaes, Christian Benedict
For the last two decades research has revealed an alarming association between short sleep duration and metabolic disorders. In tandem, the hormonal, behavioral, and genetic mechanisms underlying this relationship have been extensively investigated and reviewed. However, emerging evidence is revealing that excessive sleep duration has remarkably similar deleterious effects. Unfortunately, to date there has been little attention to what drives this connection. This narrative review therefore aims to summarize existing epidemiological findings, experimental work, and most importantly putative molecular and behavioral mechanisms connecting excessive sleep duration with both obesity and type 2 diabetes mellitus...
