[Tonsil surgery in the federal states of Germany: similarities and differences. German version].
CONCLUSION: The change of trends in tonsil surgery started long before relevant national guidelines were published. The national trend was associated with considerably less surgical activity overall, a significant decrease in ATE/TE, and a significant increase in TT. Regional differences to the national trend were identified and found to be significant in at least in 7 of 16 federal states. PMID: 31720695 [PubMed - as supplied by publisher] (Source: HNO)

Authors: Čubranić-Dobrodolac M, Švadlenka L, Čičević S, Dobrodolac M Abstract This research proposes an assessment and decision support model to use when a driver should be examined about their propensity for traffic accidents, based on an estimation of the driver's psychological traits. The proposed model was tested on a sample of 305 drivers. Each participant completed four psychological tests: the Barratt Impulsiveness Scale (BIS-11), the Aggressive Driving Behaviour Questionnaire (ADBQ), the Manchester Driver Attitude Questionnaire (DAQ) and the Questionnaire for Self-assessment of Driving Ability. ...

[Turning point in skin cancer mortality : An analysis of the trend in Germany from 1998 to 2017].
The objective of this study is to investigate current trends of skin cancer mortality in Germany. Data of the death statistics from 1998 to 2017 were analyzed using joinpoint regression models. Age standardized skin cancer mortality declined since 2013 (annual percentage change -2.1% [95% CI: -4.0 to -0.2%]), while in previous years an increase of +3.4% (95% CI: 1.3 to 5.4%) was observed. The development is mainly driven by a decreasing melanoma mortality. Possible causes of the trend change are especially the nationwide skin cancer screening which was introduced in 2008 and the growing availability of new system...

Effects of Hyperbaric Oxygen Therapy on Acute Myocardial Infarction Following Carbon Monoxide Poisoning.
Abstract Carbon monoxide poisoning (COP) may increase the risk of myocardial infarction. We conducted a study to investigate the effects of hyperbaric oxygen therapy (HBOT) on the risk. We used the Nationwide Poisoning Database in Taiwan to identify COP patients diagnosed between 1999 and 2012. We compared the risk for myocardial infarction between patients with and without HBOT by following up through 2013 and identified the independent predictors of myocardial infarction. The risk of myocardial infarction in the 7278 patients with HBOT was lower than in the 18,459 patients without HBOT, but this difference did n...

Multiple event times in the presence of informative censoring: modeling and analysis by copulas
AbstractMotivated by a breast cancer research program, this paper is concerned with the joint survivor function of multiple event times when their observations are subject to informative censoring caused by a terminating event. We formulate the correlation of the multiple event times together with the time to the terminating event by an Archimedean copula to account for the informative censoring. Adapting the widely used two-stage procedure under a copula model, we propose an easy-to-implement pseudo-likelihood based procedure for estimating the model parameters. The approach yields a new estimator for the marginal distrib...

Genome-wide accurate identification and quantification of full-length mRNA isoforms is crucial for investigating transcriptional and posttranscriptional regulatory mechanisms of biological phenomena. Despite continuing efforts in developing effective computational tools to identify or assemble full-length mRNA isoforms from second-generation RNA-seq data, it remains a challenge to accurately identify mRNA isoforms from short sequence reads owing to the substantial information loss in RNA-seq experiments.

A physician-initiated double-blind, randomised, placebo-controlled, phase 2 study evaluating the efficacy and safety of inhibition of NADPH oxidase with the first-in-class Nox-1/4 inhibitor, GKT137831, in adults with type 1 diabetes and persistently elevated urinary albumin excretion: protocol and statistical considerations
Kidney disease caused by type 1 diabetes can progress to end stage renal disease and can increase mortality risk. Nicotinamide adenine dinucleotide phosphate (NADPH) oxidase (Nox) plays a major role in producing oxidative stress in the kidney in diabetes, and its activity is attenuated by GKT137831, an oral Nox inhibitor with predominant inhibitory action on Nox-1 and Nox − 4.

Automatic delineation algorithm of reference region for amyloid imaging based on kinetics
ConclusionsAutoRef presents the same performance as the manual definition of the reference region. Further, since AutoRef is more algorithmic than the ordinary manual definition of the reference region, there are few operator-oriented uncertainties in AutoRef. We thus conclude that AutoRef can be applied as an automatic delineating algorithm for the reference region in amyloid imaging. (Source: Annals of Nuclear Medicine)

Group sequential tests for treatment effect on survival and cumulative incidence at a fixed time point
AbstractMedical research frequently involves comparing an event time of interest between treatment groups. Rather than comparing the entire survival or cumulative incidence curves, it is sometimes preferable to evaluate these probabilities at a fixed point in time. Performing a covariate adjusted analysis can improve efficiency, even in randomized clinical trials, but no currently available group sequential test for fixed point analysis provides this adjustment. This paper introduces covariate adjusted group sequential pointwise comparisons of survival and cumulative incidence probabilities. Their test statistics have an a...

This study aimed to examine the associations between the duration of folic acid (FA) supplementation, gestational diabetes mellitus (GDM), and adverse birth outcomes. A total of 950 mother-offspring pairs participated in the cohort study during 2015 in Changsha, China. The data were collected through home visits and perfected by maternal and child healthcare handbooks. Generalized linear models and stratified analyses were used for statistical analyses.

This study aims to evaluate the effectiveness of high-intensity interval training compared with no intervention and other types of training interventions for people with Type 2 Diabetes. A systematic review and meta-analysis of randomized controlled trials that used high-interval intensity training to improve anthropometric, cardiopulmonary and metabolic conditions were conducted. The search was performed during October&ndash;December 2017 using the databases PubMed, Web of Science and Physiotherapy Evidence Database (PEDro). The methodological quality of the studies was evaluated using the PEDro scale. A total of ...
