Role of trans vaginal sonography with hysteroscopy in detection of uterine causes of abortions

Background: Recurrent pregnancy loss (RPL) is one of the most frustrating and difficult areas in reproductive medicine because the aetiology is often unknown and there are only few evidence-based diagnostic and treatment strategies. Objective of this study was to compare the role of trans vaginal sonography with hysteroscopy in detection of uterine causes of abortions.Methods: This prospective cohort study was conducted in the department of obstetrics and gynaecology, Kasturba Hospital, Daryaganj, Delhi. The study was conducted from January 2016 to December 2016.Results: On transvaginal sonography majority of women i.e. 39(78%) patients had normal ultra-sonographic findings. 11(22%) showed various abnormal findings. Most commonly diagnosed abnormal finding on TVS was polyp, seen in 5(10%) patients. It was seen as a well-defined, uniformly hyperechoic mass within the endometrial cavity. normal hysteroscopic findings were seen in 27(54%) patients. Rest 23(46%) patients had abnormal uterine factors as diagnosed by hysteroscopy.Synechiae was detected in 9(18%) patients. It was the most common abnormality detected on hysteroscopy. Out of 9 patients who had synechiae, 2 had severe dense adhesions. In 6 patients, the adhesions were mild and flimsy. While minimal adhesions were noted in 1 patient, seen near the cornua.Conclusions: hysteroscopy is still the gold standard for diagnosis and most definitive procedure of choice if any kind of operative intervention is required

Role of intravenous amino acid infusion in cases of oligohydramnios and its effect on amniotic fluid index and fetal weight gain

Background: Oligohydramnios in early pregnancy is attended by serious consequences to the fetus. Various conditions associated with oligohydramnios increase perinatal mortality and morbidity. Different medical and interventional methods have been tried to treat oligohydramnios. The present study was done to study the effect of intravenous amino acid infusion on amniotic fluid index (A.F.I) and fetal weight gain.Methods: A total of 100 patients of oligohydramnios were studied. They were divided equally into study group and control group of 50 patients each by random allocation. The patients in the study group were given intravenous infusion of 200 ml of amino acid on alternate day for one week while those in the control group were not given any intervention. Both the groups were monitored for change in A.F.I and fetal weight gain by ultrasound at the end of the week.Results: The average gain in A.F.I in the study group (2.57 ± 0.68 cm) was more than in the control group (2.13 ± 0.84 cm). The average gain in fetal weight in the study group was 150.0 grams with SD of ± 37.8 grams while in the control group it was 82.14 grams with SD of ± 67.1 grams.Conclusions: Thus intravenous infusion of amino acids increases short term A.F.I and also improves fetal weight and thus has a beneficial effect to both mother and fetus in case of oligohydramnios in developing countries. However, larger studies with controlled trial are needed to be done

Search for dark matter produced in association with bottom or top quarks in √s = 13 TeV pp collisions with the ATLAS detector

A search for weakly interacting massive particle dark matter produced in association with bottom or top quarks is presented. Final states containing third-generation quarks and miss- ing transverse momentum are considered. The analysis uses 36.1 fb−1 of proton–proton collision data recorded by the ATLAS experiment at √s = 13 TeV in 2015 and 2016. No significant excess of events above the estimated backgrounds is observed. The results are in- terpreted in the framework of simplified models of spin-0 dark-matter mediators. For colour- neutral spin-0 mediators produced in association with top quarks and decaying into a pair of dark-matter particles, mediator masses below 50 GeV are excluded assuming a dark-matter candidate mass of 1 GeV and unitary couplings. For scalar and pseudoscalar mediators produced in association with bottom quarks, the search sets limits on the production cross- section of 300 times the predicted rate for mediators with masses between 10 and 50 GeV and assuming a dark-matter mass of 1 GeV and unitary coupling. Constraints on colour- charged scalar simplified models are also presented. Assuming a dark-matter particle mass of 35 GeV, mediator particles with mass below 1.1 TeV are excluded for couplings yielding a dark-matter relic density consistent with measurements

Burnout among surgeons before and during the SARS-CoV-2 pandemic: an international survey

Background: SARS-CoV-2 pandemic has had many significant impacts within the surgical realm, and surgeons have been obligated to reconsider almost every aspect of daily clinical practice. Methods: This is a cross-sectional study reported in compliance with the CHERRIES guidelines and conducted through an online platform from June 14th to July 15th, 2020. The primary outcome was the burden of burnout during the pandemic indicated by the validated Shirom-Melamed Burnout Measure. Results: Nine hundred fifty-four surgeons completed the survey. The median length of practice was 10 years; 78.2% included were male with a median age of 37 years old, 39.5% were consultants, 68.9% were general surgeons, and 55.7% were affiliated with an academic institution. Overall, there was a significant increase in the mean burnout score during the pandemic; longer years of practice and older age were significantly associated with less burnout. There were significant reductions in the median number of outpatient visits, operated cases, on-call hours, emergency visits, and research work, so, 48.2% of respondents felt that the training resources were insufficient. The majority (81.3%) of respondents reported that their hospitals were included in the management of COVID-19, 66.5% felt their roles had been minimized; 41% were asked to assist in non-surgical medical practices, and 37.6% of respondents were included in COVID-19 management. Conclusions: There was a significant burnout among trainees. Almost all aspects of clinical and research activities were affected with a significant reduction in the volume of research, outpatient clinic visits, surgical procedures, on-call hours, and emergency cases hindering the training. Trial registration: The study was registered on clicaltrials.gov "NCT04433286" on 16/06/2020

Search for direct top squark pair production in final states with two leptons in s=13\sqrt{s} = 13 TeV pppp collisions with the ATLAS detector

International audienceThe results of a search for direct pair production of top squarks in events with two opposite-charge leptons (electrons or muons) are reported, using $36.1~\hbox {fb}^{-1}$ of integrated luminosity from proton–proton collisions at $\sqrt{s}=13$ TeV collected by the ATLAS detector at the Large Hadron Collider. To cover a range of mass differences between the top squark $\tilde{t}$ and lighter supersymmetric particles, four possible decay modes of the top squark are targeted with dedicated selections: the decay $\tilde{t} \rightarrow b \tilde{\chi }_{1}^{\pm }$ into a b-quark and the lightest chargino with $\tilde{\chi }_{1}^{\pm } \rightarrow W \tilde{\chi }_{1}^{0}$ , the decay $\tilde{t} \rightarrow t \tilde{\chi }_{1}^{0}$ into an on-shell top quark and the lightest neutralino, the three-body decay $\tilde{t} \rightarrow b W \tilde{\chi }_{1}^{0}$ and the four-body decay $\tilde{t} \rightarrow b \ell \nu \tilde{\chi }_{1}^{0}$ . No significant excess of events is observed above the Standard Model background for any selection, and limits on top squarks are set as a function of the $\tilde{t}$ and $\tilde{\chi }_{1}^{0}$ masses. The results exclude at 95% confidence level $\tilde{t}$ masses up to about 720 GeV, extending the exclusion region of supersymmetric parameter space covered by previous searches
