Specifically, we studied the effects of A57G on the super-relaxed (SRX) state of myosin that may contribute to the hypercontractile cross-bridge behavior and ultimately lead to pathological cardiac remodeling in transgenic Tg-A57G mice. The disease model was compared to Tg-WT mice, expressing the wild-type human ventricular ELC, and analyzed against Tg-Δ43 mice, expressing the N-terminally truncated ELC, whose hearts hypertrophy with time but do not show any abnormalities in cardiac morphology or function. Our data suggest a new role for the N terminus of cardiac ELC (N-ELC) in modulation of myosin cross-bridge function in the healthy as well as in HCM myocardium. The lack of N-ELC in Tg-Δ43 mice was found to significantly stabilize the SRX state of myosin and increase the number of myosin heads occupying a low-energy state. In agreement, Δ43 hearts showed significantly decreased ATP utilization and low actin-activated myosin ATPase compared with A57G and WT hearts. The hypercontractile activity of A57G-ELC cross-bridges was manifested by the inhibition of the SRX state, increased number of myosin heads available for interaction with actin, and higher ATPase activity. Fiber mechanics studies, echocardiography examination, and assessment of fibrosis confirmed the development of two distinct forms of cardiac remodeling in these two ELC mouse models, with pathological cardiac hypertrophy in Tg-A57G, and near physiologic cardiac growth in Tg-Δ43 animals. © 2020 Federation of European Biochemical Societies.OBJECTIVE To discern and quantify the TB diagnostic cascade among patients registered under the Revised National TB Control Programme, Chennai city, Tamil Nadu, South India. METHODS This cross-sectional study was conducted in metropolitan Chennai from February 2017 to March 2018. We interviewed TB patients retrospectively on their diagnostic attempt in different health facilities. RESULTS Of 455 TB patients, only 4.4% received their diagnosis at their first health facility. Of 1250 visits to health facilities, the vast majority (79.4 vs. 20.6%) was in the public rather than the private sector. 56% of patients went to a public facility as the first point of care, of whom 1.6% shifted to private facilities subsequently. The remaining 54.4% shifted between up to five government health facilities. Male patients and those with a higher family income were more likely to shift from private to public. CONCLUSION Most shifts between diagnostic facilities occurred in the public sector. This necessitates interventions at public health facilities for strengthening and extending services to TB patients at their first point of care. © 2020 John Wiley & Sons Ltd.Parametric response mapping (PRM) is a novel computed tomography (CT) technology that has shown potential for assessment of bronchiolitis obliterans syndrome (BOS) after hematopoietic stem cell transplantation (HCT). The primary aim of this study was to evaluate whether variations in image acquisition under real-world conditions affect the PRM measurements of clinically diagnosed BOS. CT scans were obtained retrospectively from 72 HCT recipients with BOS and graft-versus-host disease from Fred Hutchinson Cancer Research Center, Karolinska Institute, and the University of Michigan. Volasertib Whole lung volumetric scans were performed at inspiration and expiration using site-specific acquisition and reconstruction protocols. PRM and pulmonary function measurements were assessed. Patients with moderately severe BOS at diagnosis (median forced expiratory volume at 1 second [FEV1] 53.5% predicted) had similar characteristics between sites. Variations in site-specific CT acquisition protocols had a negligible effect on the PRM-derived small airways disease (SAD), that is, BOS measurements. PRM-derived SAD was found to correlate with FEV1% predicted and FEV1/ forced vital capacity (R = -0.236, P = .046; and R = -0.689, P less then .0001, respectively), which suggests that elevated levels in the PRM measurements are primarily affected by BOS airflow obstruction and not CT scan acquisition parameters. Based on these results, PRM may be applied broadly for post-HCT diagnosis and monitoring of BOS. © 2020 The American Society of Transplantation and the American Society of Transplant Surgeons.INTRODUCTION Following allogeneic hematopoietic stem cell transplantation (alloHCT), excessive immunosuppression can be complicated by infection, while inadequate immunosuppression can result in graft-vs-host disease (GVHD). An accurate method to assess overall immune status post HCT is lacking. The QuantiFERON Monitor® (QFM) assay measures interferon gamma (IFN-γ) release from whole blood following incubation with both innate (Toll-like receptor 7, TLR7) and adaptive (CD3 antibody) stimulants and may result in a more complete assessment of the immune system. METHODS Whole blood samples were prospectively collected from alloHCT recipients at conditioning followed by days 10, 30, 60, 90, 120, and 180 post-transplant and assayed by the QFM test. IFN-γ levels were correlated to time post HCT and episodes of infection and GVHD. RESULTS Forty patients were enrolled in the study (68% male; median age 47 years; 58% matched related donors, 42% unrelated; 33% myeloablative). Post-stimulation IFN-γ levels rose steadily over the first 180 days post transplantation. IFN-γ levels were significantly lower in those with active infection compared to those without during the neutropenic period (P 1000 copies/mL) post alloHCT (P = .001). CONCLUSION This is a promising assay to demonstrate immune recovery and predict risk of infection after alloHCT and may allow tailoring of immunosuppression, antimicrobial treatment, and prophylaxis. © 2020 John Wiley & Sons A/S.

However, according to the current literature, neither dental students nor dentists feel adequately prepared to counsel smokers. The purpose of this study was to develop and implement a teaching intervention on smoking cessation for fourth-year dental students and assess its effectiveness in terms of learning outcome on knowledge, communication skills and attitudes. MATERIALS AND METHODS In this prospective intervention study, students in the intervention group (n = 28) participated in a teaching module consisting of a podcast, an interactive lecture, a seminar, and small-group sessions with role-play interactions. Knowledge, communication skills and attitudes were measured using written examinations and an objective structured clinical examination (OSCE) at the end of the module and 6 months later. Results were compared with data from a historical control group (n = 27) receiving standard teaching. RESULTS Compared with the control group, students in the intervention group had higher scores in the knowledge test (67.1% vs 41.8%; P less then .001; d = 2.8) as well as in the OSCE (74.9% vs 44.7%; P less then .001; d = 2.3) and also retained more knowledge (52.7% vs 36.5%; P less then .001; d = 2.0) and skills (71.8% vs 47.6%; P less then .001; d = 2.5) over a period of 6 months. Attitudes were similar across groups and time-points. CONCLUSION The teaching intervention equipped dental students with specific knowledge and skills required to effectively counsel smoking patients. Further research is required to assess the transfer of these skills to the clinical setting. © 2020 John Wiley & Sons A/S.

DESIGN Exploratory analysis of a randomised controlled trial. SETTING Six Australian hospitals. POPULATION Women with a singleton pregnancy enrolled in the ORIP trial. METHODS Using maternal capillary whole blood collected ~14 weeks' gestation, the fatty acids in total blood lipids were quantified using gas chromatography. Interaction tests examined whether baseline PUFA status modified the effect of omega-3 supplementation on birth outcomes. MAIN OUTCOME MEASURE Early preterm birth ( less then 34 weeks' gestation). RESULTS A low total omega-3 PUFA status in early pregnancy was associated with a higher risk of early preterm birth. Among women with a total omega-3 status ≤4.1% of total fatty acids, omega-3 supplementation substantially reduced the risk of early preterm birth compared with control (0.73 versus 3.16%; relative risk = 0.23, 95% confidence interval [CI] 0.07-0.79). Conversely, women with higher total omega-3 status in early pregnancy were at lower risk of early preterm birth. Supplementing women with a baseline status above 4.9% increased early preterm birth (2.20 versus 0.97%; relative risk = 2.27, 95% CI 1.13-4.58). CONCLUSIONS Women with singleton pregnancies and low total omega-3 PUFA status early in pregnancy have an increased risk of early preterm birth and are most likely to benefit from omega-3 supplementation to reduce this risk. Women with higher total omega-3 status are at lower risk and additional omega-3 supplementation may increase their risk. TWEETABLE ABSTRACT Low total omega-3 fat status helps identify which women benefit from extra omega-3 to reduce early prematurity. © 2020 Royal College of Obstetricians and Gynaecologists.AIM To determine the most effective DNA extraction method for bacteria in faecal samples. MATERIALS AND RESULTS This study assessed five commercial methods, that is, NucliSens easyMag, QIAamp DNA Stool Mini kit, PureLink Microbiome DNA purification kit, QIAamp PowerFecal DNA kit and RNeasy PowerMicrobiome kit, of which the latter has been optimized for DNA extraction. The DNA quantity and quality were determined using Nanodrop, Qubit and qPCR. The PowerMicrobiome kit recovered the highest DNA concentration, whereby this kit also recovered the highest gene copy number of Gram positives, Gram negatives and total bacteria. Furthermore, the PowerMicrobiome kit in combination with mechanical pre-treatment (bead beating) and with combined enzymatic and mechanical pre-treatment (proteinase K+mutanolysin+bead beating) was more effective than without pre-treatment. CONCLUSION From the five DNA extraction methods that were compared, the PowerMicrobiome kit, preceded by bead beating, which is standard included, was found to be the most effective DNA extraction method for bacteria in faecal samples. SIGNIFICANCE AND IMPACT OF THE STUDY The quantity and quality of DNA extracted from human faecal samples is a first important step to optimize molecular methods. Here we have shown that the PowerMicrobiome kit is an effective DNA extraction method for bacterial cells in faecal samples for downstream qPCR purpose. © 2020 The Authors.
