Dissociative symptoms following trauma exposure, such as derealization (i.e., feeling that one's experience is strange and unreal) and depersonalization (i.e., feeling detached from oneself) have been implicated in the development and maintenance of posttraumatic stress disorder (PTSD). In the current study, we analyzed data from a 3-year prospective cohort study of a nationally representative sample of U.S. veterans to examine whether trait dissociative symptoms, which may impair adaptive emotion regulation following trauma exposure, predict risk for the development of PTSD in trauma-exposed veterans. Results revealed that derealization symptoms predicted a nearly 5-fold increase in relative risk of incident PTSD (relative risk ratio = 4.57, 95% confidence interval = 1.55-13.52), even after adjusting for relevant sociodemographic and trauma-related factors, and severity of PTSD symptoms at baseline. To our knowledge, this study is the first to suggest that trait dissociative symptoms-specifically derealization-may be an important population-based risk factor for the development of PTSD in trauma-exposed U.S. military veterans. These findings add to a body of literature on the prediction of PTSD that largely focuses on stable or immutable risk factors such as sociodemographic and trauma characteristics, or peritraumatic emotional reactions, and underscores the potential clinical utility of assessing, monitoring, and treating derealization symptoms in trauma-exposed U.S. military veterans at risk for PTSD.
Obsessive-compulsive disorder (OCD) is a heterogeneous condition characterized by largely variable phenotypic expressions. Previous findings suggested that gender may be a relevant factor in mediating this heterogeneity. The present study aimed at exploring gender differences in a large clinical sample of Italian OCD patients.

Socio-demographic and clinical variables of a sample of 229 consecutive OCD outpatients were included in a common database. Patients were assessed through structured clinical interviews, the Yale-Brown Obsessive Compulsive Scale (Y-BOCS) and the Clinical Global Impression (CGI) scale.

Female OCD patients were more likely than males to have lifetime psychiatric comorbidities (72.6% vs 56.9%; p<0.05), poly-comorbidities being twice as high compared to males. The female group also showed a significant later onset of symptoms (63.7% vs 44.8%; p<0.005) and a higher age at first treatment (30.98±13.1 years vs 27.81±11.3; p<0.005). Moreover, the female subgroup presented higher rates of cleaning and washing compulsions, compared to the male subgroup (28.7% vs 12.6% in the male group; p<0.005).

The current study supports the notion that OCD in female gender is frequently a comorbid condition with other specific clinical characteristics compared to male patients. These findings should be considered in epidemiologic and therapeutic perspectives.

Capacity increases have previously been viewed as problematic if they increase the supervisory burden on registered nurses, and unsafe if they dilute students' supervision. The aim of this study was to assess the impact on specific patient safety measures (pressure ulcers, falls and medications errors) of having students in placement being educated in Collaborative Learning in Practice (which increases capacity) compared to when they were not. Audit data were collected from four NHS trusts in the South West of England in a retrospective cohort study. We received data on 5532 adverse events from 15 clinical areas in four NHS trusts, with 996 students on placement between January 2018 and August 2019. The risk ratio and mean differences for adverse patient events were favourable (RR = 0.9842; 95%CI 0.9604-1.008; mean difference 279, 95%CI 213-346, p = 0.01). There was no statistically significant correlation between increased student numbers and increased adverse patient events. Our data must be interpreted with caution, but we conclude that increasing capacity for student nurses in placements appears to have a positive impact on patient safety.
To analyze the impact of tube potential and iodine concentration on the visibility of calcified plaques in coronary computed tomography angiography (cCTA).

164 consecutive patients (65.9 % men and a mean age of 57.1 ± 11.3 years) with suspected coronary artery disease underwent calcium scoring (CaSc) scan followed by cCTA with topogram-based automated tube voltage selection (70 kV, 80 kV, 90 kV, 100 kV or 120 kV). In 127 Patients (HC), we injected 50 mL of contrast material (CM) with a concentration of 400 mg iodine per ml and in 37 patients (LC) 50 mL iodine concentration of 280 mg/mL. Sensitivity of cCTA for detecting calcified plaques was calculated with CaSc serving as gold standard. Density of CM enhanced coronary vessels and calcified plaques were quantified by region-of-interest (ROI) measurements in unenhanced and cCTA image series.

Overall sensitivity of cCTA to detect calcified plaques was significantly higher using LC compared to HC (79 % vs. 73 %; p = 0.0035). The impact of LC was impressive at 70 kV with an improved sensitivity of 70 % vs. 57.1 % in HC (p = 0.0082). Furthermore, density values of HC enhanced coronary vessels exceeded those of calcified plaques, especially at low kV levels. In LC, except for the 70 kV setting, higher density values were shown for calculi than enhanced vessels.

Low kV cCTA in routine using highly concentrated CM leads to reduced calcified plaque perceptibility and hence potentially underestimation of stenosis. Thus, low kV cCTA using CM with lower iodine concentration is necessary. In addition, a dose reduction up to 77.7 % can also be benefited.

Previously in vitro matured (IVM) oocytes were vitrified in minimum volume by ultra-rapid cooling technique. The oocytes were put into the equilibration solution (3% ethylene glycol in M199-HEPES + 10% foetal bovine serum) for 12 min, transferred to vitrification solution (30% ethylene glycol + 1 M sucrose in M199-HEPES + 10% foetal bovine serum) at room temperature for 25 s, then placed onto nickel electron microscopy grids and plunged into liquid nitrogen. After warming 75% of the oocytes were assessed as viable. Part of viable oocytes was taken for electron microscopy, the remaining oocytes were fertilized in vitro, and the presumptive zygotes were cultured until the blastocyst stage. Embryo cleavage and blastocyst rates in vitrified group after warming were 64.98% and 17.3%, resp. versus 70.72% and 25.54% in the control group (P less then 0.05). No significant differences were found in the blastocyst total cell number, TUNEL and dead cell indexes between both groups. Ultrastructure of vitrified oocytes showed damages in smooth endoplasmic reticulum (SER) vesicles and lipid droplets as well as irregular arrangement of solitary cortical granules. Several mitochondria were damaged and the microtubules around the chromosomes were less occurred compared to the control group. However, the extent of injuries was lower than reported by other authors studying the ultrastructure of vitrified bovine oocytes, what is also supported by the better development of our oocytes after IVF. In conclusion, the designed oocyte vitrification technique ensures obtaining the blastocysts of the quality comparable to the fresh oocytes.As a result of evolution, various finfish species have developed different breeding strategies. However, there are some similarities, and one of them is the positive effect of ovarian fluid on spermatozoa. The opposite of this phenomenon was found in the common barbel (Barbus barbus). The present study analyzed the effect of ovarian fluid (OF), distilled water (DW) and Woynarovich solution (WS) on the motility, longevity and kinetics of barbel spermatozoa. These spermatozoa parameters were also evaluated with various dilutions of ovarian fluid (OF) in relation to distilled water [04 (Group OF 0%), 13 (Group OF 25%), 11 (Group OF 50%), 31 (Group OF 75%), 40 (Group OF 100%)] and spermatozoa reactivation after a 30 s (Group OFR30s 100%) treatment in ovarian fluid. The motility analysis was carried out using computer-assisted semen analysis (CASA). The negative interaction of ovarian fluid with spermatozoa motility in the same fish species was recorded for the first time. In pure ovarian fluid, the average spermatozoa motility (MOT) decreased significantly (1.40 ± 0.94%). The negative effect of ovarian fluid-to-spermatozoa motility was reversible, and after a 30 s treatment in ovarian fluid and later dilution with water, spermatozoa motility was reactivated (from 2.25 ± 0.53% vs 69.78 ± 6.02%). this website The use of Woynarovich solution as an activator of spermatozoa movement had a positive effect (P less then 0.05) on spermatozoa movement longevity (motility up to 90 s) and the percentage of motile spermatozoa compared to distilled water (up to 45 s) and ovarian fluid (P less then 0.05).The bacterial genus, Borrelia, is comprised of vector-borne spirochete species that infect and are transmitted from multiple host species. Some Borrelia species cause highly-prevalent diseases in humans and domestic animals. Evolutionary, ecological, and molecular research on many Borrelia species have resulted in tremendous progress toward understanding the biology and natural history of these species. Yet, many outstanding questions, such as how Borrelia populations will be impacted by climate and land-use change, will require an interdisciplinary approach. The evolutionary ecology research framework incorporates theory and data from evolutionary, ecological, and molecular studies while overcoming common assumptions within each field that can hinder integration across these disciplines. Evolutionary ecology offers a framework to evaluate the ecological consequences of evolved traits and to predict how present-day ecological processes may result in further evolutionary change. Studies of microbes with complex transmission cycles, like Borrelia, which interact with multiple vertebrate hosts and arthropod vectors, are poised to leverage the power of the evolutionary ecology framework to identify the molecular interactions involved in ecological processes that result in evolutionary change. Using existing data, we outline how evolutionary ecology theory can delineate how interactions with other species and the physical environment create selective forces or impact migration of Borrelia populations and result in micro-evolutionary changes. We further discuss the ecological and molecular consequences of those micro-evolutionary changes. While many of the currently outstanding questions will necessitate new experimental designs and additional empirical data, many others can be addressed immediately by integrating existing molecular and ecological data within an evolutionary ecology framework.
