BACKGROUND Direct oral anticoagulants (DOACs) are recommended over vitamin K antagonists (VKAs) for the treatment of venous thromboembolism (VTE). Concomitant antiplatelet therapy may potentiate the antithrombotic effects of DOACs. OBJECTIVES We evaluated the impact of concomitant antiplatelet therapy on the efficacy and safety of DOACs. PATIENTS/METHODS MEDLINE, EMBASE, and Clinicaltrial.gov were searched for randomized controlled trials of DOACs for the treatment of acute VTE. The efficacy outcome was symptomatic recurrent VTE and VTE-related death; the primary safety outcome was major bleeding. RESULTS Six randomized controlled trials included 26,924 patients of whom 3,550 (13.2%) received concomitant antiplatelet therapy, mainly aspirin (67.7%). Concomitant antiplatelet therapy did not reduce the incidence of recurrent VTE and VTE-related death with any oral anticoagulant (odds ratio [OR] 1.17; 95% confidence interval [CI], 0.92-1.48), with DOACs (OR 1.21; 95% CI, 0.86-1.71), or VKAs alone (OR 1.16; 95% CI, 0.77-1.73). Compared with no antiplatelet therapy, concomitant antiplatelet therapy was associated with a higher risk of major bleeding in patients with any oral anticoagulant (OR 1.79; 95% CI, 1.22-2.63), DOACs (OR 1.89; 95% CI, 1.04-3.44) or VKAs (OR 1.73; 95% CI, 1.16-2.59). In patients receiving concomitant antiplatelet therapy, there were no statistically significant differences in efficacy or safety outcomes with DOACs or VKAs (OR 0.99; 95% CI, 0.64-1.51, and OR 0.68; 95% CI, 0.32-1.45, respectively). CONCLUSIONS Concomitant use of antiplatelet therapy with oral anticoagulants does not appear to affect the risk of recurrent VTE and increases the risk of major bleeding.

However, the role and mechanism of miR-330-3p in GDM are rarely reported. In this research, we aim to investigate the effects of miR-330-3p on GDM. METHODS MiR-330-3p expression in the GDM patients' blood was determined by q-PCR. Blood glucose of blood samples was detected using blood glucose detection kits. Glucokinase (GCK) was confirmed to be a target gene of miR-330-3p by bioinformatics and luciferase analysis. Correlations between miR-330-3p with GCK and blood glucose were analyzed by Pearson correlation analysis. After INS-1 cells were treated with glucose and transfected with mimic, inhibitor or siGCK, GCK expression was detected by western blot, and q-PCR, enzyme-linked immunosorbent assays, cell counting kit-8 and Annexin-V/propidium iodide were conducted to examine the expression of insulin, cell viability and apoptosis. RESULTS MiR-330-3p was high-expressed in GDM patients' blood, while GCK was low-expressed. The miR-330-3p expression level positively correlated with blood glucoseand and it was highly expressed in glucose-treated INS-1 cells (11 and 22 mmol/L), while miR-330-3p expression negatively correlated with GCK expression. GCK expression was inhibited by miR-330-3p mimic and enhanced by the miR-330-3p inhibitor. MiR-330-3p mimic inhibited INS-1 cells' insulin expression, cell viability and induced apoptosis. Yet miR-330-3p inhibitor and siGCK exhibited opposite effects which miR-330-3p mimic and GCK played on INS-1 cells. In addition, siGCK reversed the effect of miR-330-3p inhibitor on INS-1 cells. CONCLUSION Our findings proved that miR-330-3p targeting GCK lead to the dysfunction of INS-1 cells in GDM, and could become a therapeutic target for GDM treatment. © 2020 Japan Society of Obstetrics and Gynecology.Teachers are guided by an ethical code of conduct. Teacher behavior can be perceived as normative and can set standards, for example, in the field of animal experimentation. The importance of ethical standards raises the question of its transmission. This survey addressed the relevance of using large amphitheater teaching groups to educate students on the ethical aspects of animal experimentation. A course was built to include interactivity sequences to gather feedback from students about moral dilemmas or assertions about animal experimentation. To that end, surveys were conducted on third-year students, prior to the course, shortly after the course, and at the end of the academic year. Students were asked to indicate whether the experimental protocols were satisfactory. Before the course, few students reported ethical dimensions in the proposed protocols; animals were considered scientific objects, not sentient beings. The situation was noticeably different for students on courses with an emphasis on the animal as the unit of study. Though large classrooms are not believed to be relevant places to question ethical issues, the proportion of students discussing ethical aspects of protocols increased shortly after the lecture, and was increased at the end of the academic year. These observations suggest that the effect of teaching on ethical considerations was sustainable despite the lectures being performed in a large classroom. This article is protected by copyright.

SETTING AND SAMPLE POPULATION In this retrospective study, the data of a total of 52,609 subjects who underwent cone-beam computed tomography (CBCT) for diagnosis and treatment were reviewed. According to the inclusion and exclusion criteria, 183 subjects with impacted mandibular second molars and 176 age- and sex-matched controls were included. METHODS A retrospective case-control study was designed. The 183 subjects were divided into two groups group 1 (G1) comprised 120 patients with unilaterally impacted mandibular second molars, and group 2 (G2) comprised 63 patients with bilaterally impacted mandibular second molars. Group 3 (G3) contained 176 age- and sex-matched controls. The mandible was reconstructed with nineteen landmarks using Mimics software. Twelve linear lengths and 3 angles were measured. RESULTS The bilateral germination gap, mandibular body width and gonion width in G1 were significantly lower than those in G3 (P less then 0.
