Motherwort (YiMuCao), a traditional Chinese herb, has been shown beneficial effects for women's diseases. This meta-analysis aimed to evaluate the efficacy and safety of motherwort injection add-on therapy to carboprost tromethamine for prevention of post-partum blood loss. A systematic literature search was conducted in PubMed, Embase, Cochrane Library, CNKI, VIP and Wanfang from their inception to December 2017. Randomized controlled trials that determined the add-on effects of motherwort injection to carboprost for prevention of post-partum blood loss were eligible. Pooled risk ratio (RR) and mean difference (MD) with 95% confidence interval (CI) were used to summarize the effect sizes. Eight trials including 1276 pregnant women fulfilled the inclusion criteria. Prophylactic use of motherwort injection add-on therapy significantly reduced the post-partum 2 h (MD −127.5 mL; 95% CI −149.13 to −105.88) and 24 h (MD −146.85 mL; 95% CI −179.77 to −113.94) blood loss and incidence of post-partum hemorrhage (RR 0.28; 95% CI 0.17-0.45) than carboprost. Moreover, adjunctive treatment with motherwort injection significantly decreased the length of the third stage of labor (MD −3.41 min; 95% CI −4.33 to −2.49) and duration of lochia (MD −7.13 days; 95% CI −8.49 to −5.76). There was no statistical significant difference in the incidence of adverse events (RR 0.76; 95% CI 0.50-1.16). Prophylactic use of motherwort injection add-on therapy to carboprost tromethamine could reduce post-partum blood loss. However, more well-designed trials are necessary to confirm the findings of this study due to the methodological flaws of the included trials.
Invasive mucinous adenocarcinoma (IMA) is an uncommon entity in the lung, with a poor prognosis. Multifocal IMA of the lung is even more unusual, and there is little experience with effective treatments. Herein, we present a case of multifocal IMA diagnosed in a 36 year‐old man by video‐assisted thoracoscopic surgery. A right middle lobe and a nodule in the right upper lobe were resected, as were mediastinal lymph nodes, leaving behind an autonomous right lower lobe nodule. To explore the feasibility of molecular treatment, next‐generation sequencing of genetic mutations was performed after four cycles of chemotherapy (pemetrexed + cisplatin). Ultimately, a KIAA 1468‐ RET fusion gene was detected at a disproportionate level (~67.3%), indicating that targeted therapy may be efficacious in treating this disease.
Trapped lung is defined by the lung's inability to expand and fill the thoracic cavity because of a restricting “peel” caused by benign or malignant pleural disease. However, trapped lung secondary to pneumothorax is rarely reported. We present a case of trapped lung caused by a pneumothorax that occurred some 14 years before the patient presented to our hospital with a complaint of incapacitating dyspnea. Computed tomography (CT) scans revealed trapping of the right lung with abnormal thickening of the visceral pleura. In view of the patient's history of pneumothorax, we concluded that his dyspnea was attributable mainly to the trapping of his lung by the earlier pneumothorax. We therefore scheduled thoracoscopic decortication, which was successfully completed. The patient's recovery after the operation was uneventful, and seven weeks after surgery the right lung had re‐expanded well.
Studies have yielded contradictory results concerning the association between dehydroepiandrosterone sulfate (DHEAS) and mortality in the elderly population. This meta-analysis aimed to evaluate the association of low serum DHEAS level with cardiovascular or all-cause mortality in the elderly population. A comprehensive literature search was conducted in PubMed and Embase databases up to 4 February, 2019. Longitudinal observational studies reporting multivariate adjusted risk ratio (RR) and corresponding 95% confidence intervals (CI) for cardiovascular or all-cause mortality with respect to baseline low DHEAS level were included. Both fixed-effect and random effect model were used to pool the overall risk estimate. Methodological quality of the included studies was evaluated using a 9-point Newcastle-Ottawa Scale. Six prospective studies enrolling 6,744 individuals were identified. Five studies were graded as high methodological quality. When compared the lowest to the reference higher circulating DHEAS level, the pooled RR of all-cause and cardiovascular mortality was 1.46 (95% CI: 1.25-1.70) and 1.49 (95% CI: 1.11-1.99), respectively. Subgroup analysis indicated that the association of low DHEAS level with all-cause mortality risk was only found in men (RR 1.41;95% CI: 1.18-1.69) but not in women (RR 1.72; 95% CI: 0.99-2.99). This meta-analysis provides evidence that low circulating DHEAS level is associated with increased risk all-cause mortality in the elderly population.
Objective: To evaluate the impact of postoperative acute kidney injury (AKI) on early and long-term mortality in patients with acute aortic dissection by conducting a meta-analysis. Methods: An extensive literature search was performed in PubMed and Embase databases until February 15, 2020. Observational studies that reported the associations between postoperative AKI and early (in-hospital and within 30 days) or long-term mortality in patients with acute aortic dissection were included. Results: Seven studies comprising 1525 acute aortic dissection patients were identified. A random effect meta-analysis showed that postoperative AKI was significantly associated with higher risk of long-term mortality (risk ratio [RR] 2.32; 95% confidence interval [CI] 1.50–3.59). Subgroup analysis revealed that the pooled RR of long-term mortality was 1.42 (95% CI 0.90–2.22) for stage 1 AKI, 1.72 (95% CI 0.95–3.12) for stage 2 AKI, and 4.46 (95% CI 2.72–7.32) for stage 3 AKI, respectively. Furthermore, postoperative stage 3 AKI was associated with an increased risk of early mortality (RR 11.3; 95% CI 4.2–30.5). Conclusions: This meta-analysis provided clinical evidence that postoperative stage 3 AKI is associated with higher risk of early and long-term mortality, even after adjusting important confounding factors. However, the current findings should be interpreted with caution due to the retrospective nature and limited number of studies analyzed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
