The Prognostic Value of Renal Function in Acute Pulmonary Embolism—A Multi-Centre Cohort Study
2018
Background Haemodynamic alterations caused by acute pulmonary embolism (PE) may affect multi-organ function including kidneys. This multi-centre, multinational cohort study aimed to validate the prognostic significance of estimated glomerular filtration rate (eGFR) and its potential additive value to the current PE risk assessment algorithms. Methods The post hoc analysis of pooled prospective cohort studies: 2,845 consecutive patients (1,424 M/1,421 F, 66 ± 17 years) with confirmed acute PE and followed up for 180 days. We tested prognostic value of pre-specified eGFR level ≤60 mL/min/1.73 m2 calculated on admission according to the Modification of Diet in Renal Disease study equation. Th…

Objectives To investigate the association between IL18RAP and body mass index (BMI) and obesity and to verify the effect of a polymorphism in the microRNA136 (MIR136) IL18RAP binding region. Design We analysed samples from two Spanish cross-sectional studies, VALCAR (Spanish Mediterranean coast) and Hortega (Spanish centre). These studies aimed at analysing cardiovascular risk and development of cardiovascular disease in the general population. Both populations correspond to regions with different characteristics. Setting Five IL18RAP single nucleotide polymorphisms were selected using the SYSNPs web tool and analysed by oligonucleotide ligation assay (SNPlex). For the MIR136 functional stu…
''Sex Difference In Open-water Ultra-swim Performance In the Longest Freshwater Lake Swim In Europe''
2013
Eichenberger, Evelyn | Knechtle, Beat | Knechtle, Patrizia | Ruest, Christoph A. | Rosemann, Thomas | Lepers, Romuald | Senn, Oliver; International audience; ''This study examined participation and performance trends in the 26.4-km open-water ultra-swim "Marathon Swim in Lake Zurich," Switzerland. A total of 461 athletes (157 women and 304 men) finished the race between 1987 and 2011. The mean age of the finishers during the studied period was 32.0 +/- 6.5 years for men and 30.9 +/- 7.2 years for women. The mean age of finishers and the age of winners increased significantly across years for both sexes (p 0.05). The swimming time performance remained stable (p > 0.05) for both sexes across …
Meta-analysis
2012
Treatment of the pain caused by chronic pancreatitis (CP) is not standardized. Knowledge of the response to placebo in this setting may aid the design of future trials. We aimed at investigating the placebo effect on abdominal pain remission rates in patients with CP.MEDLINE, EMBASE, and Scopus were searched, and randomized placebo-controlled trials in CP providing data on abdominal pain remission rates in placebo arms were included. Pooled estimates of the placebo rate were calculated using random-effects logistic regression analysis. Stratum-specific rates for different patients and study-level covariates were calculated to account for heterogeneity.Seven randomized controlled trials (202…
A method of measuring the apical base
1996
SUMMARY The maxillary and mandibular apical base areas were measured, using a gnathograph, on the study casts of 156 adults and children representing Class II division 1, Class II division 2 and Class III malocclusions. There were significant differences between the groups at each age. The maxillary apical base areas tended to be smaller for the adults than for the children in all three occlusal classes. By contrast, the mandibular apical base areas tended to be larger for the adults than for the children, except in Class II division 1 malocclusion. Following a logarithmic transformation to stabilize the variance, regression lines were fitted to relate the size of the maxillary and mandibul…
Declining Sexual Activity and Desire in Men—Findings From Representative German Surveys, 2005 and 2016
2017
Abstract Background Surveys have indicated an increase of sexual activity in aging men; recently, however, a decrease of sexual activity has been reported in young men. Aim To assess (i) sexual activity and desire and their determinants across the age range in a population-based male sample and (ii) their changes over 11 years. Methods A representative survey of men (N = 1,095) 18 to 93 years old from 2016 was compared with a survey from 2005 (N = 1,106 men) with the same age range. Samples were drawn from the German population at random using standardized sampling procedures. Questions were filled out by participants in the presence of a trained interviewer. Sexual activity was compared us…
The Effect of Hypertensive Disorders of Pregnancy on the Risk of ADHD in the Offspring
2017
Objective: Evidence suggests that perinatal factors may contribute to the development of ADHD. Our objective was to examine the association between hypertensive disorders of pregnancy (HDP) and ADHD, and behavioral difficulties among 7-year-old children. Method: The study cohort consisted of 13,192 children (weighted = 13,500) who participated in the Millennium Cohort Study (MCS) at age 7. HDP (raised blood pressure, preeclampsia, eclampsia, and toxemia) were reported by mothers 9 months postdelivery. ADHD was reported by parents at age 7 years. Weighted logistic regression models were used to assess the association. Results: In all, 1,069 (7.9%) women reported HDP and 166 (1.2%) children h…
Dental and periodontal lesions in patients with gastro-oesophageal reflux disease.
2003
Dental erosion has been considered an extraesophageal manifestation of gastro-oesophageal reflux disease, but few reports have studied the relationship between this disease and other periodontal or dental lesions. The aim of this study was to investigate the prevalence of dental and periodontal lesions in patients with gastro-oesophageal reflux disease.A total of 253 subjects were prospectively studied between April 1998 and May 2000. Two study groups were established: 181 patients with gastro-oesophageal reflux disease and 72 healthy volunteers. Clinical assessment, including body mass index and consumption of tobacco and alcohol, was performed in all subjects, as well as a dental and peri…
Implicit versus explicit attitude to doping: which better predicts athletes’ vigilance towards unintentional doping?
2018
Abstract Objectives This preliminary study examined whether implicit doping attitude, explicit doping attitude, or both, predicted athletes’ vigilance towards unintentional doping. Design A cross-sectional correlational design. Methods Australian athletes (N = 143; Mage = 18.13, SD = 4.63) completed measures of implicit doping attitude (brief single-category implicit association test), explicit doping attitude (Performance Enhancement Attitude Scale), avoidance of unintentional doping (Self-Reported Treatment Adherence Scale), and behavioural vigilance task of unintentional doping (reading the ingredients of an unfamiliar food product). Results Positive implicit doping attitude and explicit…
Corneal and Refractive Astigmatism in Adults: A Power Vectors Analysis
2009
Purpose. In this article, we examine the relationship between corneal and refractive astigmatism (including with the rule, against-the-rule, and oblique astigmatism) in an adult population using power vectors. Methods. Refractive and keratometric measures of astigmatism were conducted on right eyes of 105 white subjects aged 18 to 59 years. We performed a linear regression of refractive astigmatic error on corneal astigmatism, using the J0 and J45 components of the astigmatism. Results. We obtained a statistically significant regression relationship between the corneal (C) and refractive (R) astigmatism for both J0 and J45 components, namely, RJ0 = 1.07 × CJ0 − 0.28; and RJ45 = 1.46 × CJ45 …
