We investigated relationships between outdoor air pollution and pterygium in Korean adults. This study includes 23,276 adults in population-based cross-sectional data using the Korea National Health and Nutrition Examination Survey 2008-2011. Pterygium was assessed using slit lamp biomicroscopy. Air pollution data (humidity, particulate matter with aerodynamic diameter less than 10 μm [PM₁₀], ozone [O₃], nitrogen dioxide [NO₂], and sulfur dioxide levels [SO₂]) for 2 years preceding the ocular examinations were acquired...

Very few cases of patients with myasthenia gravis (MG) who later developed amyotrophic lateral sclerosis (ALS) have been described, although some studies showed that significantly more cases than expected have ALS associated with a prior diagnosis of autoimmune diseases. Our aim was to investigate whether the association of ALS and MG was higher than expected in a population-based study and to describe the clinical features characterizing these patients. In Emilia Romagna Region of Italy, a prospective registry has been collecting all incident ALS cases since 1...

AIMS: Low socioeconomic status (SES) characterizes smoking and nicotine dependence in adult samples. However, less is known about how parental SES is linked to smoking in offspring and the potential mechanisms at work. METHODS: A population-based longitudinal study (n=1380) from Norway was used. Participants were followed from their mid-teens until their late 20s using survey and register data. Data were collected on parental education, parental smoking, educational aspirations and expectations, school grades and school-related conduct problems...

BACKGROUND: Lung cancer is the leading cause of cancer death worldwide. Clinically appropriate cancer-directed surgery is an influential and significant prognostic factor. In a population-based study, we determined how urban/rural residence was related to surgery receipt for patients with non-small cell lung cancer. We assessed the relationship between relative survival and patients' area of residence, taking into account surgery receipt and area socioeconomic level. METHODS: We extracted data from the National Cancer Registry Ireland on patients with non-small cell lung cancer diagnosed during 1994-2011 and linked to area-level data on socioeconomic indicators and urban/rural categories...

Having a system to stratify individuals according to risk is key to clinical disease prevention, this allows individuals identified at different risk tiers benefit from further investigation and intervention. But the same risk score estimated for two different persons doesn't mean they need the same further investigation or represent the similarity health condition between two persons. Meanwhile, users still does not know a prior what most of the risk tiers are, and how many tiers should be found in risk stratification...

PURPOSE: Statins are widely used by older persons in primary and secondary prevention of cardiovascular disease. Although serious adverse events are rare, many statin users report mild muscle pain and/or muscle weakness. It's unclear what impact statins exert on a patient's daily life. Research on statin related side effects in older persons is relatively scarce. We therefore investigated the relation between statin use and self-reported hindering muscle complaints in older persons in the general population...

A major roadblock to understanding how microbes in the gastrointestinal tract colonize and influence the physiology of their hosts is our inability to genetically manipulate new bacterial species and experimentally assess the function of their genes. We describe the application of population-based genomic sequencing after chemical mutagenesis to map bacterial genes responsible for motility in Exiguobacterium acetylicum, a representative intestinal Firmicutes bacterium that is intractable to molecular genetic manipulation...

Genetics and lifestyle independently determine dementia risk, but the interaction is unclear. We assessed the interactive relationship of apolipoprotein E (APOE) genotype and physical exercise on dementia risk over a 5-year period in 1,646 older adults from the Canadian Study of Health and Aging who were dementia-free at baseline. Physical exercise moderated the relationship between genotype and dementia (p < 0.01). Specifically, for APOE ɛ4 non-carriers, the odds of developing dementia were higher in non-exercisers than exercisers (OR = 1...

OBJECTIVE The aim of this study was to assess myelomeningocele mortality, correlate these findings to lesion level, and investigate mortality evolution. METHODS From the population-based western Denmark myelomeningocele database, the authors extracted the records of 187 patients born between January 1, 1970, and July 1, 2015. Patients were categorized according to their most rostral lesion level into cervical, thoracic, lumbar, or sacral groups. Furthermore, patients were categorized based on their birth dates (1970-1979, 1980-1989, and 1990-2015)...

Ovarian cancer is the most fatal gynecologic cancer and is an important source of cancer-related mortality, particularly in developed countries. Despite substantial research examining adiposity (primarily adult body mass index [BMI]), the overall evidence suggests only a weak positive association between adiposity and risk of ovarian cancer, with stronger associations observed for population-based case-control studies compared to prospective studies. Ovarian cancer is not one disease and emerging data suggest that higher BMI may only be associated with risk of certain histologic subtypes, including low-grade serous and invasive mucinous tumors...
