Epigenome-wide association study of whole blood gene expression in Framingham Heart Study participants provides molecular insight into the potential role of CHRNA5 in cigarette smoking-related lung diseases.

Background: DNA methylation is a key epigenetic modification that can directly affect gene regulation. DNA methylation is highly influenced by environmental factors such as cigarette smoking, which is causally related to chronic obstructive pulmonary disease (COPD) and lung cancer. To date, there have been few large-scale, combined analyses of DNA methylation and gene expression and their interrelations with lung diseases.

Implementation of an integrated care programme to avoid fragility fractures of the hip in older adults in 18 Bavarian hospitals - study protocol for the cluster-randomised controlled fracture liaison service FLS-CARE.

Background: The economic and public health burden of fragility fractures of the hip in Germany is high. The likelihood of requiring long-term care and the risk of suffering from a secondary fracture increases substantially after sustaining an initial fracture. Neither appropriate confirmatory diagnostics of the suspected underlying osteoporosis nor therapy, which are well-recognised approaches to reduce the burden of fragility fractures, are routinely initiated in the German healthcare system.

Neural processes of reward and punishment processing in childhood and adolescence: An event-related potential study on age differences.

Reward and punishment processing are subject to substantial developmental changes during youth. However, little is known about the neurophysiological correlates that are associated with these developmental changes, particularly with regard to both anticipatory and outcome processing stages. Thus, the aim of this study was to address this research gap in a sample of typically developing children and adolescents.

Shared Genetics of Multiple System Atrophy and Inflammatory Bowel Disease.

Background: Multiple system atrophy (MSA) is a rare neurodegenerative disease characterized by intracellular accumulations of α-synuclein and nerve cell loss in striatonigral and olivopontocerebellar structures. Epidemiological and clinical studies have reported potential involvement of autoimmune mechanisms in MSA pathogenesis. However, genetic etiology of this interaction remains unknown.

Genome-wide association meta-analysis for early age-related macular degeneration highlights novel loci and insights for advanced disease.

Background: Advanced age-related macular degeneration (AMD) is a leading cause of blindness. While around half of the genetic contribution to advanced AMD has been uncovered, little is known about the genetic architecture of early AMD.

Methods: To identify genetic factors for early AMD, we conducted a genome-wide association study (GWAS) meta-analysis (14,034 cases, 91,214 controls, 11 sources of data including the International AMD Genomics Consortium, IAMDGC, and UK Biobank, UKBB).

Genetic Determinants of Electrocardiographic P-Wave Duration and Relation to Atrial Fibrillation.

Background: The P-wave duration (PWD) is an electrocardiographic measurement that represents cardiac conduction in the atria. Shortened or prolonged PWD is associated with atrial fibrillation (AF). We used exome-chip data to examine the associations between common and rare variants with PWD.

Basic life support knowledge in Germany and the influences of demographic factors.

Background: In the developed world, cardiovascular diseases still contribute to mortality and morbidity, leading to significantly increased deaths in recent years. Thus, it is necessary for a layperson to provide the best possible basic life support (BLS) until professional help is available. Since information on current BLS knowledge in Germany is not available, but necessary to be able to make targeted improvements in BLS education, we conducted this study.

Multi-ancestry GWAS of the electrocardiographic PR interval identifies 202 loci underlying cardiac conduction.

The electrocardiographic PR interval reflects atrioventricular conduction, and is associated with conduction abnormalities, pacemaker implantation, atrial fibrillation (AF), and cardiovascular mortality. Here we report a multi-ancestry (N = 293,051) genome-wide association meta-analysis for the PR interval, discovering 202 loci of which 141 have not previously been reported. Variants at identified loci increase the percentage of heritability explained, from 33.

Burn first aid knowledge in Germany and the influences of social-economic factors.

Background: Optimal management of burns always starts with the first aid. Results of numerous studies carried out in different countries indicated in general a low awareness of first aid of burns irrespective of whether the income of the country was high, middle or low. The aim of the study was to investigate the knowledge in burn first aid in Germany and compare it to an Australian study from 2013.

The use of circulating cell-free tumor DNA in routine diagnostics of metastatic melanoma patients.

Modern advances in technology such as next-generation sequencing and digital PCR make detection of minor circulating cell-free tumor DNA amounts in blood from cancer patients possible. Samples can be obtained minimal-invasively, tested for treatment-determining genetic alterations and are considered to reflect the genetic constitution of the whole tumor mass. Furthermore, tumor development can be determined by a time course of the quantified circulating cell-free tumor DNA.

Epigenetic Link Between Statin Therapy and Type 2 Diabetes.

Objective: To investigate the role of epigenetics in statins' diabetogenic effect comparing DNA methylation (DNAm) between statin users and nonusers in an epigenome-wide association study in blood.

Research Design And Methods: Five cohort studies' participants ( = 8,270) were classified as statin users when they were on statin therapy at the time of DNAm assessment with Illumina 450K or EPIC array or noncurrent users otherwise. Associations of DNAm with various outcomes like incident type 2 diabetes, plasma glucose, insulin, and insulin resistance (HOMA of insulin resistance [HOMA-IR]) as well as with gene expression were investigated.

PR interval genome-wide association meta-analysis identifies 50 loci associated with atrial and atrioventricular electrical activity.

Electrocardiographic PR interval measures atrio-ventricular depolarization and conduction, and abnormal PR interval is a risk factor for atrial fibrillation and heart block. Our genome-wide association study of over 92,000 European-descent individuals identifies 44 PR interval loci (34 novel). Examination of these loci reveals known and previously not-yet-reported biological processes involved in cardiac atrial electrical activity.

Rural versus urban differences in end-of-life care for lung cancer patients in Germany.

Purpose: To assess rural-urban differences in healthcare utilization and supportive care at the end-of-life in German lung cancer patients.

Methods: We identified 12,929 patients with incident lung cancer in 2009 from claims data and categorized them to four district types (major city, urban, rural, remote rural). We compared site of death, unplanned hospitalizations, hospital days, outpatient doctor, general practitioner (GP) and home visits, structured palliative care, therapy with antidepressants, pain relief medication and chemotherapy, and therapeutic puncturing in the last 30 and 14 days of life using mixed models with logistic link function for binary outcomes and log link function for count data.
