PURPOSE: The pivotal trials for stroke prevention in non-valvular atrial fibrillation (NVAF) compared rivaroxaban, dabigatran, and apixaban with warfarin, as did most claims-based studies. Comparisons with phenprocoumon, the most frequently used vitamin K antagonist (VKA) in Germany, are scarce. METHODS: Risk of bleeding, ischemic stroke, and all-cause mortality in patients with NVAF were analyzed using data for 2010 to 2014 from a large German claims database. New users of oral anticoagulants from January 2012 to December 2013 were included and observed over 1 year...

INTRODUCTION AND HYPOTHESIS: Vaginal mesh surgery is subject of debate due to the impact of mesh-related complications on patient's lives. Not all of these complications are symptomatic. Restoration of the anatomy and improvement of pelvic floor function as a result may counter the experienced discomfort related to adverse events. We hypothesized that health-related quality of life (HR-QoL) is comparable in women after vaginal mesh surgery regardless of the presence or absence of a mesh-specific complication...

The manufacturing of insensitive munition 2,4-dinitroanisole (DNAN) generates waste streams that require treatment. DNAN has been treated previously with zero-valent iron (ZVI) and Fe-based bimetals. Use of Mg-based bimetals offers certain advantages including potential higher reactivity and relative insensitivity to pH conditions. This work reports preliminary findings of DNAN degradation by three Mg-based bimetals: Mg/Cu, Mg/Ni, and Mg/Zn. Treatment of DNAN by all three bimetals is highly effective in aqueous solutions (> 89% removal) and wastewater (> 91% removal) in comparison with treatment solely with zero-valent magnesium (ZVMg; 35% removal)...

BACKGROUND: Pregnancy after bariatric surgery (BS) has an increased risk for small-for-gestational-age infants (SGA), shorter length of gestation, and probably perinatal mortality. The aim of this study was to investigate if biliopancreatic diversion could impair pregnancy outcomes in comparison to other bariatric surgery procedures. METHODS: We conducted a cohort retrospective single-center study in 65 women before and after BS. Thirty-one pregnancies occurred before BS, while 109 after BS, amongst which n = 51 after biliopancreatic diversion (BPD) and n = 58 after non-malabsorptive procedures...

In recent years, many studies on the analysis of microplastics (MP) in environmental samples have been published. These studies are hardly comparable due to different sampling, sample preparation, as well as identification and quantification techniques. Here, MP identification is one of the crucial pitfalls. Visual identification approaches using morphological criteria alone often lead to significant errors, being especially true for MP fibers. Reliable, chemical structure-based identification methods are indispensable...

RATIONALE: Adult rat 22-kHz vocalizations are often associated with alarm or distress, whereas a subset of 50-kHz calls is preferentially emitted in response to amphetamine and other rewarding stimuli. Whether any 50-kHz calls reflect anxiety is unknown. OBJECTIVE: To determine the effects of anxiogenic drugs on 50-kHz call rate and call subtype profile, in comparison with D-amphetamine. METHODS: Adult male rats received systemic amphetamine (1 mg/kg) three times several days before testing...

The basis and contribution of mesopores created in ZSM-5 structures at different treatment conditions are systematically investigated. The results reveal that the mesopores originated from the alkali dissolution of pristine ZSM-5 are mainly intracrystalline and they contribute to excessive Brønsted acid sites, while the mesopores originated from the re-assembly of alkali dissolved aluminosilicate species possess Lewis acid sites. These ZSM-5 mesostructures showed an extended lifespan during the cracking of cumene (88...

The detection of high-frequency spectral notches has been shown to be worse at 70-80 dB sound pressure level (SPL) than at higher levels up to 100 dB SPL. The performance improvement at levels higher than 70-80 dB SPL has been related to an 'ideal observer' comparison of population auditory nerve spike trains to stimuli with and without high-frequency spectral notches. Insofar as vertical localization partly relies on information provided by pinna-based high-frequency spectral notches, we hypothesized that localization would be worse at 70-80 dB SPL than at higher levels...

Climate change places considerable stress on riverine ecosystems by altering flow regimes and increasing water temperature. This study evaluated how water temperature increases under climate change scenarios will affect stream invertebrates in pristine headwater streams. The studied headwater-stream sites were distributed within a temperate catchment of Japan and had similar hydraulic-geographical conditions, but were subject to varying temperature conditions due to altitudinal differences (100 to 850 m)...

A systematic method in hydrophilic interaction chromatography (HILIC) was developed for the separation of four monophosphate nucleotides using design of experiment (DOE) approaches. Three HPLC parameters, the buffer concentration (ammonium acetate concentration), gradient time, and temperature, were evaluated within the quality design framework, and the effects on chromatographic parameters were investigated. Four zwitterionic columns (ZIC-HILIC, ZIC-cHILIC, NUCLEODUR HILIC, and PC HILIC) were used to separate four nucleotides, and the HPLC conditions for each column were successfully optimized, although PC HILIC did not give peaks that were suitable for optimization...

BACKGROUND: Depressed patients are at increased risk to fall victim to a violent crime compared to the general population. It remains unknown whether their increased risk persists after remission. This study compared victimization rates of remitted patients with both a random general population sample and a group of currently depressed patients. Furthermore, this study aimed to identify predictors of future violent victimization. METHODS: In this longitudinal study conducted in the Netherlands, 12-month prevalence rates of sexual assaults, physical assaults, and threats were assessed with the Safety Monitor in 140 currently remitted patients with recurrent depression, and compared to those of a weighted general population sample (N = 9...

Oxytocin (OT) is a neuropeptide which influences the expression of social behavior and regulates its distribution according to the social context - OT is associated with increased pro-social effects in the absence of social threat and defensive aggression when threats are present. The present experiments investigated the effects of OT beyond that of social behavior by using a discriminative Pavlovian fear conditioning protocol with rats. In Experiment 1, an OT receptor agonist (TGOT) microinjected into the basolateral amygdala facilitated the discrimination between an auditory cue that signaled shock and another auditory cue that signaled the absence of shock...
