Few studies have evaluated the impact of lifetime abuse on quality of life (QoL) among older adults. By using a multinational study authors aimed to assess the subjective perception of QoL among people who have reported abuse during the course of their lifetime. The respondents (N = 4,467; 2,559 women) were between the ages of 60 and 84 years and living in seven European countries (Germany, Greece, Italy, Lithuania, Portugal, Spain, and Sweden). Lifetime abuse was assessed by using a structured questionnaire that allowed to assess lifetime experiences of abuse...

Glioblastoma is the commonest malignant brain tumor in adults. Most patients develop progressive disease before they die. However, survival after developing progressive disease is infrequently reported. We identified patients with histologically proven disease who were treated with concurrent chemoradiotherapy during 2006-2013. We analyzed overall survival (OS), progression-free survival and postprogression survival (PPS) in relation to age, O6-methylguanine-DNA methyltransferase promoter methylation and extent of surgical resection...

De Quervain's tenosynovitis is a repetitive strain injury involving synovial inflammation of the tendons of the first extensor compartment of the wrist. It is relatively common in the general population, and is the most common radial-sided tendinopathy seen in athletes. Identifying a genetic marker associated with de Quervain's tenosynovitis could provide a useful tool to help identify those individuals with an increased risk for injury. A genome-wide association screen was performed using publically available data from the Research Program in Genes, Environment and Health (RPGEH) including 4,129 cases and 98,374 controls...

There is growing concern that much of the published research literature is distorted by the pursuit of statistically significant results. In a seminal article, Ioannidis and Trikalinos (2007, Clinical Trials) proposed an omnibus (I&T) test for significance chasing (SC) biases. This test compares the observed number of studies that report statistically-significant results, against their expected number based on study power, assuming a common effect size across studies. The current article extends this approach by developing a Bayesian nonparametric (BNP) meta-regression model and test of SC bias, which can diagnose bias at the individual study level...

Greece has undergone a distressing crisis that has taken a heavy toll, devaluing lives of individuals and functions of society at large. Besides the economic meltdown, there has been an even worse crisis of values. The country currently occupies a low rank in the WHO Happiness Index (1) (99(th) in 2016 and 87(th) in 2017), not so much because of worsening ranking in healthy life expectancy (still ranked 24(th) in the world in 2017) or even wealth (still ranked 44(th) in GDP per capita), but because of mediocre ranking in social support (ranked 80(th) ) and extremely low rankings in freedom to make life choices (ranked 150(th) among 155 countries), generosity (ranked 155(th) , i...

Motivation: Interpreting genetic variation in noncoding regions of the genome is an important challenge for personal genome analysis. One mechanism by which noncoding single nucleotide variations (SNVs) influence downstream phenotypes is through the regulation of gene expression. Methods to predict whether or not individual SNVs are likely to regulate gene expression would aid interpretation of variants of unknown significance identified in whole-genome sequencing studies. Results: We developed FIRE (Functional Inference of Regulators of Expression), a tool to score both noncoding and coding SNVs based on their potential to regulate the expression levels of nearby genes...

Ankle injuries, including sprains, strains and other joint derangements and instability, are common, especially for athletes involved in indoor court or jumping sports. Identifying genetic loci associated with these ankle injuries could shed light on their etiologies. A genome-wide association screen was performed using publicly available data from the Research Program in Genes, Environment and Health (RPGEH) including 1,694 cases of ankle injury and 97,646 controls. An indel (chr21:47156779:D) that lies close to a collagen gene, COL18A1, showed an association with ankle injury at genome-wide significance (p = 3...

Glioblastoma (GBM) represents 80% of all primary malignant brain tumours in adults. Prognosis is poor, and there is a clear correlation between disease progression and deterioration in functional status. In this pilot study we assess whether we can estimate disease progression and progression free survival (PFS) from routinely collected electronic healthcare data. We identified fifty patients with glioblastoma who had chemo-radiotherapy. For each patient we manually collected a reference data set recording demographics, surgery, radiotherapy, chemotherapy, follow-up and death...

Low voltage and high voltage high-rupturing-capacity fuse links are used in LV and HV installations respectively, protecting mainly the LV and HV electricity distribution and transportation networks. The Waste Electrical and Electronic Equipment Directive (2002/96/EC) for "Waste of electrical and electronic equipment" is the main related legislation and as it concerns electrical and electronic equipment, it includes electric fuses. Although, the fuse links consist of recyclable materials, only small scale actions have been implemented for their recycling around Europe...

BACKGROUND: Confounding bias is a most pervasive threat to validity of observational epidemiological research. METHODS: We assessed whether authors of observational epidemiological studies consider confounding bias when interpreting the findings. We randomly selected 120 cohort or case-control studies published in 2011 and 2012 by the general medical, epidemiological, and specialty journals with the highest impact factors. We used Web of Science to assess citation metrics through January 2017...

A mathematical model describing the sampling process in a permeation-based passive sampler was developed and evaluated numerically. The model was applied to the Waterloo Membrane Sampler (WMS), which employs a polydimethylsiloxane (PDMS) membrane as a permeation barrier, and an adsorbent as a receiving phase. Samplers of this kind are used for sampling volatile organic compounds (VOC) from air and soil gas. The model predicts the spatio-temporal variation of sorbed and free analyte concentrations within the sampler components (membrane, sorbent bed and dead volume), from which the uptake rate throughout the sampling process can be determined...

Age simulation suits are used to demonstrate typical physical impairments of older age (e.g., strength and sensory losses) in younger individuals. The purpose of the current study was to describe gait performance in different age groups while wearing an age simulation suit. A total of 178 participants ages 18 to 85 (mean age = 50.4 years, SD = 16.4 years) were assigned according to their age decade to four groups with (ages 18 to 59) and two groups without (ages 60 to 85) the aging suit. Gait performance was measured with a gait analysis system (GAITRite(®)) while walking at a self-chosen pace...

Most physicians and other healthcare professionals are unaware of the pervasiveness of poor quality clinical evidence that contributes considerably to overuse, underuse, avoidable adverse events, missed opportunities for right care and wasted healthcare resources. The Medical Misinformation Mess comprises four key problems. First, much published medical research is not reliable or is of uncertain reliability, offers no benefit to patients, or is not useful to decision makers. Second, most healthcare professionals are not aware of this problem...

Design and fabrication of many next-generation liquid crystal (LC)-based devices rely on nematic LC domains in the form of drops or emulsions. In addition to surfactants, solid nanoparticles may be used to stabilize LC-in-water Pickering emulsions, possibly adding new dimensions to device functionality. In this work we quantitatively study the adsorption of ethyl cellulose (EC) nanoparticles, as a colloid model system, on the 4-cyano-4'-pentylbiphenyl (5CB)-water interface via a series of dynamic interfacial tension measurements...
