PURPOSE To investigate the impact of menstrual cycle on patients undergoing gynecological endoscopic surgery. PATIENTS AND METHODS 220 patients scheduled for gynecological endoscopic surgery under general anesthesia were selected. The patients were divided into three groups based on 3 phases of menstrual cycle which are the follicular phase (Group F), ovulatory phase (Group O) or luteal phase (Group L). It is based on their duration of menstruation and the last day of menstrual bleeding from the date of surgery. Primary outcomes were the incidences of early and late postoperative nausea and vomiting (PONV) in the three patient groups.  https://www.selleckchem.com/products/azd-5462.html  Preoperative venous blood was taken to determine the estrogen and progesterone levels of the patients. RESULTS A total of 207 patients were enrolled. The incidence of early PONV was highest in group O (22.22% vs 43.33% vs 17.86%, P  less then  0.01). Multivariate logistic regression showed that menstrual cycle (P  less then  0.01) and sufentanil dosage (P  less then  0.05) were independent risk factors for early PONV, menstrual cycle (P = 0.03) and intraoperative hypotension (P = 0.03) were independent risk factors for late PONV. After the propensity matching, the incidences of early and late PONV in group O were both higher than that in other two groups (19.23% vs 44.68% vs 16.90%, P  less then  0.01; 53.80% vs 72.34% vs 45.07%, P = 0.01). CONCLUSION The incidence of PONV after gynecological endoscopic surgery was different in patients with different menstrual cycles, with the highest incidence in ovulation.The indiscriminate use of pesticides has caused several damages to the environment, in particular the pollution of water reservoirs, so that this has motivated the development of techniques to minimize its consequences. One of the main surface water pollutants is glyphosate, which is a widely used herbicide for weed control. Therefore, in this work, computational simulations were used with density functional theory and molecular dynamics to theoretically verify if C60 fullerene is capable of adsorbing glyphosate in aqueous media. As a result, we showed through the adsorption energies, molecular dynamics methods, and infrared absorption that C60 can adsorb glyphosate molecules in at least three distinct configurations, either in vacuum or in water, which theoretically indicates it as a good candidate for removal of this herbicide from water by nanotechnology techniques.In the current SARS-CoV-2 pandemic there are many questions regarding the safe treatment of patients with inflammatory rheumatic diseases. Many of these questions cannot yet be answered on an evidence-based basis and this does not make patient care easy. The German Society for Rheumatology (DGRh) hopes that these initial recommendations will provide support for specific issues in the care of patients with inflammatory rheumatic diseases in view of the current threat posed by SARS-CoV-2. In order to take advantage of the dynamic worldwide gain in knowledge for our patients, the recommendations will be updated regularly. The updated versions of the recommendations are deposited on the homepage of the DGRh.The study assessed changes in the total 16 PAH (polycyclic aromatic hydrocarbon) content of soil which occurred in 1998-2009, during a multi-annual, manure-mineral and mineral fertilisation experiment, carried out in Bałcyny near Ostróda (Poland), according to a design unchanged since 1986 The study focused on the impact of multi-annual, diversified mineral fertilisation (N, P, K, Mg and Ca) compared to manure applied every two years at a dose of 40 t/ha. The four plants used in the crop rotation included sugar beet, spring barley, maize and spring wheat. The content of the total 16 polycyclic aromatic hydrocarbons was significantly higher in the manure-fertilised soil than in the soil fertilised with mineral fertilisers only. Under the regular manure fertilisation conditions, liming of the soil significantly increased the total 16 PAH content, and the lowest dose of nitrogen significantly decreased its PAH content. The lowest nitrogen dose had an opposite effect in the soil fertilised with mineral fertilisers only, where it caused a significant increase in the content of the PAHs. However, the increased doses of nitrogen also resulted in an increase in the PAH content in the soil fertilised with manure and without this fertiliser.OBJECTIVES Computed tomography (CT) pulmonary angiography is widely used in patients with suspected pulmonary hypertension (PH). However, the diagnostic and prognostic significance remains unclear. The aim of this study was to (a) build a diagnostic CT model and (b) test its prognostic significance. METHODS Consecutive patients with suspected PH undergoing routine CT pulmonary angiography and right heart catheterisation (RHC) were identified. Axial and reconstructed images were used to derive CT metrics. Multivariate regression analysis was performed in the derivation cohort to identify a diagnostic CT model to predict mPAP ≥ 25 mmHg (the existing ESC guideline definition of PH) and > 20 mmHg (the new threshold proposed at the 6th World Symposium on PH). In the validation cohort, sensitivity, specificity and compromise CT thresholds were identified with receiver operating characteristic (ROC) analysis. The prognostic value of the CT model was assessed using Kaplan-Meier analysis. RESULTS Between 2012 and 2016, 491 patients were identified. In the derivation cohort (n = 247), a CT model was identified including pulmonary artery diameter, right ventricular outflow tract thickness, septal angle and left ventricular area. In the validation cohort (n = 244), the model was diagnostic, with an area under the ROC curve of 0.94/0.91 for mPAP ≥ 25/> 20 mmHg respectively. In the validation cohort, 93 patients died; mean follow-up was 42 months. The diagnostic thresholds for the CT model were prognostic, log rank, all p  less then  0.01. DISCUSSION In suspected PH, a diagnostic CT model had diagnostic and prognostic utility. KEY POINTS • Diagnostic CT models have high diagnostic accuracy in a tertiary referral population of with suspected PH. • Diagnostic CT models stratify patients by mortality in suspected PH.
