They find wide variation in survival among families, and this survival is linked to differences in gene expression patterns. Their study elucidates the importance of combining different data types to characterize within-population phenotypic variation and understand how that variation may lead to genetic adaptation under stressful conditions. © 2020 John Wiley & Sons Ltd.BACKGROUND, AIM, AND HYPOTHESIS This randomized controlled trial aimed to compare the impact of a physician’s attire on the perceptions of patients with cancer of compassion, professionalism, and physician preference. Our hypothesis was that patients would perceive the physician with formal attire as more compassionate than the physician wearing casual attire. MATERIALS AND METHODS One hundred five adult follow-up patients with advanced cancer were randomized to watch two standardized, 3-minute video vignettes with the same script, depicting a routine physician-patient clinic encounter. Videos included a physician in formal attire with tie and buttoned-up white coat and casual attire without a tie or white coat. Actors, patients, and investigators were all blinded to the purpose and videos watched, respectively. After each video, patients completed validated questionnaires rating their perception of physician compassion, professionalism, and their overall preference for the physician. RESULTS There were no sipreferences vary geographically, are influenced by cultural beliefs, and may vary based on particular care settings. Previous studies consisted of nonblinded surveys and found increasing confidence in physicians wearing a professional white coat. Unfortunately, there are no randomized controlled trials, to the authors’ knowledge, to confirm the survey findings. In this randomized, blinded clinical trial the researchers found that physician’s attire did not affect patients’ perception of the physician’s level of compassion and professionalism. Attire also did not influence the patients’ preferences for their doctor or their trust and confidence in the doctor’s ability to provide care. © AlphaMed Press 2020.OBJECTIVE To report the clinical use of a cavitron ultrasonic surgical aspirator (CUSA) for the resection of hepatic lesions in dogs. STUDY DESIGN Clinical prospective study. ANIMALS Eleven client-owned dogs. METHODS Dogs requiring a hepatic nodulectomy, segmentectomy, and/or a lobectomy (including complex lobectomies) were enrolled. The number and location of procedures, blood loss, duration of surgery, and short-term complications were recorded. RESULTS Dogs underwent a mean of 2.3 ± 1.1 procedures. All masses were amenable to surgical excision regardless of their location and their relationship with major hepatic vessels. Dogs lost a median of 77 mL of blood (9.9-161), which corresponded to 4.3% of blood volume (0.8%-23.2%). The dog with the highest blood loss survived without requiring transfusion. The median duration of all CUSA procedures was 33.5 minutes (15-82). Short-term outcomes were assessed for the first 15 days, during which two complications were diagnosed. Cholangiohepatitis was diagnosed in one dog and resolved after medical management, and another dog developed necrotic pancreatitis and died. CONCLUSION Liver parenchyma-sparing nodulectomies and segmentectomies and liver lobectomies including complex lobectomies were achieved with a CUSA in all dogs. CLINICAL SIGNIFICANCE Use of a CUSA can be considered as an alternative for the removal of hepatic lesions in dogs. © 2020 The American College of Veterinary Surgeons.Covalent organic frameworks (COFs) enable precise integration of various organic building blocks into porous skeletons through topology predesign. Here, we report the first example of COFs by integrating electron withdrawing bromine group onto the skeletons for triboelectric nanogenerators (TENG). The resulting framework exhibits high surface area and good crystallinity. Thus, bromine functionalized COF has more regular aligned π columns and arrays over the skeleton than bare COFs, which in turn significantly enhances charge transport ability. As a result, bromine functionalized COFs showed higher electrical output performance at 5Hz with a peak value of short circuit current density of 43.6 µA and output voltage of 416 V, which is 2 and 1.3 times higher than those of bare COFs (21.6 µA and 318 V), respectively. These results demonstrated that this strategy for engineering electron withdrawing groups on the skeleton could open a new aspect of COFs for developing TENG device. © 2020 WILEY-VCH Verlag GmbH & Co.

STUDY DESIGN Experimental study. SAMPLE POPULATION Eight paired harvested femurs. METHODS Femurs were assigned to knotted or knotless configuration. Equal numbers of right and left femurs were tested. The caudolateral femoral condyle at the distal pole of the lateral fabella (F2 site) was drilled. The assigned configuration with braided suture combined with the bone anchor was implanted into the F2 site. Each configuration was positioned into a mechanical testing machine to measure yield load, load at 3-mm displacement, ultimate load, stiffness, and mode of failure at the beginning of the canine standing phase angle (150°). RESULTS Mean ultimate load was 100.14 and 88.69 N (P = .798), mean yield load was 59.72 and 55.85 N (P = .708), load at 3-mm displacement was 46.72 and 43.33 N (P = .656), and stiffness was calculated to be 43.06 and 47.09 N/mm (P = .548) for knotted and knotless configurations, respectively. Mode of failure occurred primarily by anchor pull-out. CONCLUSION The bone anchor withstood deformation at the estimated forces applied on the native cranial cruciate ligament (CCL) of toy breed dogs in both configurations. CLINICAL SIGNIFICANCE This bone anchor may constitute a useful alternative for stabilization of the CCL deficient stifle in toy breed dogs. However, before it can be recommended for widespread use in dogs, closely monitored clinical trials must be conducted to assess outcome and complications associated with this implant. © 2020 The American College of Veterinary Surgeons.3,4-Methylenedioxymethamphetamine (MDMA)-assisted psychotherapy for posttraumatic stress disorder (PTSD) has been shown to significantly reduce clinical symptomatology, but posttraumatic growth (PTG), which consists of positive changes in self-perception, interpersonal relationships, or philosophy of life, has not been studied with this treatment. Participant data (n = 60) were pooled from three Phase 2 clinical studies employing triple-blind crossover designs. Participants were required to meet DSM-IV-R criteria for PTSD with a score higher than 50 on the Clinician-Administered PTSD Scale (CAPS-IV) as well as previous inadequate response to pharmacological and/or psychotherapeutic treatment. Data were aggregated into two groups an active MDMA dose group (75-125 mg of MDMA; n = 45) or placebo/active control (0-40 mg of MDMA; n = 15). Measures included the Posttraumatic Growth Inventory (PTGI) and the CAPS-IV, which were administered at baseline, primary endpoint, treatment exit, and 12-month follow-up. At primary endpoint, the MDMA group demonstrated more PTG, Hedges’ g = 1.14, 95% CI [0.49, 1.78], p less then .001; and a larger reduction in PTSD symptom severity, Hedges’ g = 0.88, 95% CI [-0.28, 1.50], p less then .001, relative to the control group. Relative to baseline, at the 12-month follow-up, within-subject PTG was higher, p less then .001; PTSD symptom severity scores were lower, p less then .001; and two-thirds of participants (67.2%) no longer met criteria for PTSD. MDMA-assisted psychotherapy for PTSD resulted in PTG and clinical symptom reductions of large-magnitude effect sizes. Results suggest that PTG may provide a new mechanism of action warranting further study. © 2020 Multidisciplinary Association for Psychedelic Studies, Inc.

We investigated whether temperament in preadolescence influences body weight and the development of eating pathology in adolescence and young adulthood. METHOD This study used data from TRAILS (Tracking Adolescents’ Individual Lives Survey), a Dutch community cohort study (N = 2,230) from preadolescence into adulthood. At age 11, the temperament dimensions negative affectivity and effortful control were measured with the Early Adolescent Temperament Questionnaire-Revised. Body mass index (BMI) was measured at all assessment waves. At age 19, the prevalence of eating disorders was investigated by two-stage screening including interviews by eating disorder experts. At age 22 and 26, the Eating Disorder Diagnostic Scale was used to assess the level of eating pathology. RESULTS Higher negative affectivity in preadolescence was associated with higher BMI and eating pathology in young adulthood. Lower effortful control in preadolescence was found to be a risk factor for the development of obesity in young adulthood. No association was found between effortful control in preadolescence and eating pathology in later life. DISCUSSION Both negative affectivity and effortful control play a role in the development of weight or eating problems during adolescence. © 2020 The Authors.

We focused on the analysis of their performance for through space charge-transfer (CT) excitations which are well known to be very problematic for commonly used functionals, such as global hybrids.Two different families of functionals were compared, each of them containing pure, hybrid and double-hybrid functionals.The results obtained show that, beside the robustness of the implementation, these functionals provide results with an accuracy comparable to that of adjusted range-separated functionals, with the relevant difference that for DHs no parameter is tuned on specific compounds thus making them more appealing for a general use. Furthermore, the algorithm described and implemented is characterized by the same computational cost scaling as that of the ground state algorithm employed for MP2 and double hybrids. © 2020 Wiley Periodicals, Inc.This study estimated gender differences in the posttraumatic stress disorder (PTSD) symptom network structure (i.e., the unique associations across symptoms) using network analysis in a Latin American sample. learn more Participants were 1,104 adults, taken from epidemiological studies of mental health following natural disasters and accidents in Mexico and Ecuador. Symptoms of DSM-IV PTSD were measured dichotomously with the Spanish version of the Composite International Diagnostic Interview. We estimated the PTSD symptom network of the full sample and in male and female subsamples as well as indices of centrality, the stability and accuracy of the modeled networks, and communities of nodes within each network. The male and female networks were compared statistically using the Network Comparison Test (NCT). Results indicated strength centrality was the only stable centrality measure, with correlation stability (CS) coefficients of .59, .28, and .44 for the full, male, and female networks, respectively. We found the most central symptoms, measured by strength centrality, were loss of interest and flashbacks for men; and concentration impairment, avoiding thoughts/feelings, and physiological reactivity for women.
