Recent population-based data on nonalcoholic fatty liver disease (NAFLD) epidemiology in general and incidence in particular, are lacking. We examined trends in NAFLD incidence in a US community, and the impact of NAFLD on incident metabolic comorbidities (MC), cardiovascular (CV) events and mortality. A community cohort of all adults diagnosed with NAFLD in Olmsted County, MN between 1997-2014 was constructed using the Rochester Epidemiology Project database. The yearly incidence rate was calculated. The impact of NAFLD on incident MC, CV events and mortality was studied using a multi-state model, with a 4:1 age and sex-matched general population as reference...

BACKGROUND: The iodine status of populations is usually assessed by median urinary iodine concentrations (UIC) in population-based studies, but it is unclear to which extent UIC are comparable across different laboratories. The aim of our study was to investigate the variability of UIC measurements across three well-established German laboratories with long-term clinical-chemical expertise in iodine measurements and to compare these results to the gold standard inductively coupled plasma mass spectrometry (ICP-MS)...

The natural history of oral human papillomavirus (HPV) infection which is linked with the increased incidence of oropharyngeal squamous cell cancer (OPSCC) has been incompletely studied. Oral swab specimens and questionnaire data were obtained bi-annually for up to 6 visits from 4314 healthy adults aged 25-69 in rural Anyang, China. HPV infection status was evaluated with PCR-based sequencing. Participants with at least two consecutive valid HPV results within the study period were included in the incidence and clearance analysis...

Population based studies showing the negative impact of type 2 diabetes (T2D) on lung function are overviewed. Among the well-recognized pathophysiological mechanisms, the metabolic pathways related to insulin resistance, low-grade chronic inflammation, leptin resistance, microvascular damage, and autonomic neuropathy are emphasized. Histopathological changes are exposed, and findings reported from experimental models are clearly differentiated from those described in humans. The accelerated decline in pulmonary function that appears in patients with cystic fibrosis with related abnormalities of glucose tolerance and diabetes is considered as an example to further investigate the relationship between T2D and the lung...

Context: High homocysteine concentrations are associated with maternal pregnancy complications and low birth weight, jaundice and cerebrovascular accidents in neonates. Thyroid hormone may interfere with homocysteine metabolism via stimulation of vitamin B12- and folate-dependent processes and via effects on enzymes of the re-methylation pathway. Objective: Investigating the associations of maternal and neonatal thyroid function with homocysteine during pregnancy and after delivery, respectively...

Human vision quality is influenced by ocular aberrations, including astigmatism and higher-order aberrations (HOAs), in combination with other optical factors. In this study, we introduce the results and perceptions of previous studies investigating these aberrations. We also introduce our results obtained as part of the Yamagata Study (Funagata), a population-based epidemiologic study. To investigate the astigmatic change with age, researchers have used the power vector analysis, allowing incorporation of the magnitude and axis of astigmatism into statistical analyses...

It is unknown whether physiological ageing also goes along with electromechanical asynchrony of contraction. Aim of the study was to evaluate synchrony of contraction in older people with ("non-healthy") or without ("healthy") evidence for structural cardiac disease. In 547 persons (age 76.7+/-5.5 years, 306 male, 241 female) recruited from a population-based cohort of the ActiFE-Um study including a random sample of people >/= 65 years old living in the region of Ulm, Germany, various PW- and TDI-Doppler based markers for asynchrony were obtained by echocardiography...

Background and Aims: There has been increasing evidence that vitamin D deficiency may increase the risk of metabolic syndrome. Since metabolic syndrome is a major risk factor for non-alcoholic fatty liver disease (NAFLD), we aimed to investigate the association between vitamin D and the severity and mortality of NAFLD. Methods: Data was obtained from the United States Third National Health and Nutrition Examination Survey conducted in 1988-1994, with follow-up mortality data through 2011. NAFLD was defined by ultrasonographic detection of hepatic steatosis in the absence of other liver diseases and categorized as normal, mild, moderate or severe...

Interpretations of genetic data concerning the prehistory of Europe have long been a subject of great debate, but increasing amounts of ancient and modern DNA data are now providing new and more informative evidence. Y-chromosome resequencing studies in Europe have highlighted the prevalence of recent expansions of male lineages, and focused interest on the Bronze Age as a period of cultural and demographic change. These findings contrast with phylogeographic studies based on mitochondrial DNA (mtDNA), which have been interpreted as supporting expansions from glacial refugia...
