Major complications associated with unfavorable outcome in right-sided large hemisphere infarctions: A single-center study.

OBJECTIVES: To identify the major complications independently associated with unfavorable outcomes in right-sided large hemisphere infarction (RLHI) patients. METHODS: We retrospectively enrolled consecutive patients admitted within 24 h with the diagnosis of RLHI. The unfavorable outcome was defined as a modified Rankin Scale score of 4-6 at 3 months. Univariate and multivariate analyses were performed to identify the major complications independently associated with 3-month unfavorable outcomes. RESULTS: Of the 171 cases with RLHI included, 126 (73.7%) had unfavorable outcomes at 3 months: A total of 64 (37.4%) cases died, and 62 (36.3%) lived with severe disability. Stroke-related complications occurred in 168 (98.2%) patients during hospitalization. The five most common stroke-related complications were pulmonary infection (75.4%), electrolyte disorder (61.4%), hypoalbuminemia (49.1%), malignant brain edema (MBE) (48.5%), and hemorrhagic transformation (48.0%). RLHI patients with unfavorable outcomes had more frequent MBE (58.7% vs. 21.4%, p < .001), pulmonary infection (86.5% vs. 42.9%, p < .001), gastrointestinal bleeding (46.8% vs. 28.6%, p = .038), electrolyte disorder (68.3% vs. 40.5%, p = .001), acute renal failure (32.5% vs. 4.8%, p < .001), and hypoalbuminemia (61.1% vs. 11.9%, p < .001) than patients with favorable outcome. Multivariate analyses suggested that only MBE (adjusted OR 4.06, 95% confidence interval [CI] 1.14-14.48, p = .031), pulmonary infection (adjusted OR 4.69, 95%CI 1.48-14.85, p = .009), and hypoalbuminemia (adjusted OR 6.58, 95%CI 1.74-24.86, p = .005) were independently associated with 3-month unfavorable outcome in patients with RLHI. CONCLUSIONS: Most of the RLHI patients have at least one stroke-related complication during hospitalization, and nearly three-quarters suffered unfavorable outcomes. Only MBE, pulmonary infection, and hypoalbuminemia are independently associated with 3-month unfavorable outcome.

Incidence of maternal venous thromboembolism in China: A systematic review and meta-analysis.

BACKGROUND: Venous thromboembolism (VTE) is one of the primary causes of maternal death. Although many studies have reported maternal VTE, no study has estimated the incidence of it in China. OBJECTIVES: The aim of this work was to estimate the incidence of maternal VTE in China and to compare the risk factors for it. SEARCH STRATEGY: The authors searched eight platforms and databases including PubMed, Embase, and Cochrane Library from inception to April 2022, with the search terms "venous thromboembolism" AND "puerperium (pregnancy)" AND "incidence" AND "China." SELECTION CRITERIA: Studies provide data to calculate the incidence of maternal VTE among Chinese patients. DATA COLLECTION AND ANALYSIS: The authors made a standardized table to collect data and calculated the incidence and 95% confidence intervals (CIs), founding source of heterogeneity by subgroup analysis and meta-regression and judging publication bias by funnel plot and Egger test. MAIN RESULTS: The included 53 papers with a total sample size of 3 813 871 patients had 2539 cases of VTE, and the incidence of maternal VTE in China was 0.13% (95% CI, 0.11-0.16; P < 0.001). CONCLUSIONS: The trend in the incidence of maternal VTE in China is stable. Cesarean section and advanced age are associated with a higher incidence of VTE.

Single cell RNA sequencing research in maternal fetal interface.

The maternal-fetal interface is an essential environment for embryonic growth and development, and a successful pregnancy depends on the dynamic balance of the microenvironment at the maternal-fetal interface. Single-cell sequencing, which unlike bulk sequencing that provides averaged data, is a robust method for interpreting the cellular and molecular landscape at single-cell resolution. With the support of single-cell sequencing, the issue of maternal-fetal interface heterogeneity during pregnancy has been more deeply elaborated and understood, which is important for a deeper understanding of physiological and pathological pregnancy. In this paper, we analyze the recent studies of single-cell transcriptomics in the maternal-fetal interface, and provide new directions for understanding and treating various pathological pregnancies.
