Growing evidence has suggested that hyperhomocysteinemia (HHcy) is a risk factor for cerebral infarction. However, the effect of HHcy on postoperative cerebral ischemia is still unclear. We aim to investigate the relationship between HHcy and postoperative ischemia of adult patients with moyamoya disease (MMD). A total of 138 adult patients with MMD were prospectively recruited from July 1 to December 31, 2019. After excluding 14 patients accepting conservative therapy, all 124 patients who underwent surgical treatment were enrolled. Patients were grouped according to postoperative ischemia and HHcy presentation, respectively. Clinical data and laboratory examinations were compared by statistical analyses. Potential risk factors were evaluated by univariate and multivariate logistic regression analysis. Comparing to the normal, patients with postoperative ischemia were higher in serum homocysteine (Hcy) level (P = 0.039) and HHcy ratio (P = 0.035). Furthermore, HHcy was more common in males (P = 0.007) than females. Logistic analysis results showed that HHcy (OR 5.234, 95% CI 1.127-24.315; P = 0.035) was an independent risk factor. HHcy was significantly associated with postoperative ischemia in MMD patients. Our study found that HHcy was correlated to the risk of postoperative ischemia. HHcy can be used as an indicator and a potential therapeutic target for postoperative ischemia in adult patients with MMD. URL http//www.chictr.org .

Force fields are sets of functions and parameters used to calculate the potential energy of a chemical system as a function of the atomic coordinates. Despite the widespread use of force fields, their inadequacies are often thought to contribute to systematic errors in molecular simulations. Furthermore, different force fields tend to give varying results on the same systems with the same simulation settings. Here, we present a pipeline for comparing the geometries of small molecule conformers. We aimed to identify molecules or chemistries that are particularly informative for future force field development because they display inconsistencies between force fields. We applied our pipeline to a subset of the eMolecules database, and highlighted molecules that appear to be parameterized inconsistently across different force fields. We then identified over-represented functional groups in these molecule sets. The molecules and moieties identified by this pipeline may be particularly helpful for future force field parameterization.
There are two approaches for treating cytomegalovirus (CMV) infection occurring after kidney transplantation (KTx). One is preemptive therapy in which treatment is started after confirming positive CMV antigenemia using periodic antigenemia assay. The other approach is prophylactic therapy in which oral valganciclovir (VGCV) is started within 10days after KTx and continued for 200days. The Transplantation Society guidelines recommend prophylactic therapy for high-risk (donor's CMV-IgG antibody positive and recipient's negative) pediatric recipients. Selleckchem Rigosertib However, the adequate dose and side effects of VGCV are not clear in children, and there is no sufficient information about prophylaxis for Japanese pediatric recipients.

A single-center retrospective analysis was conducted on case series of high-risk pediatric patients who underwent KTx and received oral VGCV prophylaxis at the Department of Pediatric Nephrology, Tokyo Women's Medical University, between August 2018 and March 2019. Data were collected using medical records.

The dose of administration was 450mg in all the study patients (n = 5). Reduction or discontinuation was required in four of five patients due to adverse events, which included neutropenia in one patient, anemia in two patients, and neutropenia and digestive symptoms in one patient. Late-onset CMV disease occurred in all patients. No seroconversion was observed during prophylaxis.

Our preliminary study suggests that the dosage endorsed by The Transplantation Society may be an overdose for Japanese pediatric recipients. Further studies are required to examine the safety and efficacy of VGCV prophylaxis in Japanese pediatric recipients.

The purpose of this study was to verify the risk factors present in patients on the kidney transplant waiting list that may interfere with the incidence of cardiovascular (CV) events and death during the first 12months after transplantation.

Based on the data collected prospectively during pretransplant workups, a retrospective study was conducted including 665 patients followed up until death or completing 12months posttransplantation. Endpoints were the composite incidence of CV events and death.

The prevalence of diabetes, LV hypertrophy, and CV disease at baseline was high; 14% of patients had angina, 26% an abnormal myocardial scan, and 47% coronary artery disease. CV events occurred in 53 patients (8.4%) and in 29 (55%) caused death. The independent predictors of events were age ≥ 50years (HR 2.292; CI% 1.093-4.806), angina (HR 1.969; CI% 1.039-3.732), and altered myocardial scan (HR 1.905, CI% 1.059-3.428). Altered myocardial scan (HR 2.822, 95% CI 1.095-6.660) was also one of the independent predictor of CV death.

The incidence of CV events and death were predicted by variables associated with myocardial ischemia, a potentially modifiable risk factor. Patients with pretransplantation myocardial ischemia should be considered at a higher risk of developing early CV complications and managed accordingly before, during, and after kidney transplantation.
