A 20-cm cut umbilical cord milking may not benefit the preterm infants < 30 week's gestation: A randomized clinical trial
Journal of the Formosan Medical Association = Taiwan yi zhi. 2021
BACKGROUND/PURPOSE To evaluate whether a shorter length (20 cm) of C-UCM has potential benefits, compared to immediate cord clamping (ICC), in very preterm babies. METHODS Inborn preterm infants less than 30 weeks of gestational age (GA) were randomly assigned to the 20-cm C-UMC and ICC groups. The primary outcome was the need for packed red blood cell (pRBC) transfusion before the 21st day of life. The secondary outcomes were short- and long-term outcomes related to premature birth. RESULTS Seventy-six neonates were randomized to the two groups. GA were 27.2 ± 1.8 and 27.5 ± 1.7 weeks (p = 0.389) and birth weights were 987 ± 269 and 1023 ± 313 g (p = 0.601) in the 20-cm C-UCM and ICC groups, respectively. There was no significant difference between the groups in terms of the need for pRBC transfusion before the 21st day of life (59.4% versus 71.8%, adjusted odds ratio [aOR] 0.311, 95% confidence interval [CI] 0.090-1.079). An increased prevalence of late-onset sepsis was observed in the 20-cm C-UCM group compared to the ICC group (21.6% versus 5.1%, aOR 5.434, 95% CI 1.033-23.580). The mortality rates were 13.5% and 2.6% in the 20-cm C-UCM and ICC groups, respectively (aOR 5.339, 95% CI 0.563-50.626). The neurodevelopmental outcomes at 2 years of corrected age between the groups were also not statistically significant. CONCLUSION A 20-cm C-UCM showed no effect on reducing the incidence of pRBC transfusion in preterm babies with GA less than 30 weeks compared with ICC in this small-scale randomized controlled trial.
Does statin increase the risk of intracerebral hemorrhage in stroke survivors? A meta-analysis and trial sequential analysis
Therapeutic advances in neurological disorders. 2019;12:1756286419864830
Background: It remains debatable whether statin increases the risk of intracerebral hemorrhage (ICH) in poststroke patients. Methods: We systematically searched PubMed, EMBASE, and CENTRAL for randomized controlled trials. Trial sequential analysis (TSA) was conducted to assess the reliability and conclusiveness of the available evidence in the meta-analysis. To evaluate the overall effectiveness, the net composite endpoints were derived by totaling ischemic stroke, hemorrhagic stroke, transient ischemic attack (TIA), myocardial infarction, and cardiovascular mortality. Results: A total of 17 trials with 11,576 subjects with previous ischemic stroke, TIA, or ICH were included, in which statin therapy increased the risk of hemorrhagic stroke (risk ratio [RR], 1.42; 95% confidence interval [CI], 1.07-1.87), but reduced the risk of ischemic stroke (RR, 0.85; 95% CI, 0.75-0.95). For the net composite endpoints, statin therapy was associated with a 17% risk reduction (95% CI, 12-21%; number needed to treat = 6). With a control event rate 2% and RR increase 40%, the TSA suggested a conclusive signal of an increased risk of hemorrhagic stroke in stroke survivors taking statin. However, with the sensitivity analysis by changing assumptions, the conclusions about hemorrhagic stroke risk were less robust. Conclusions: Statin therapy in poststroke patients increased the risk of hemorrhagic stroke but effectively reduced ischemic stroke risk. Weighing the benefits and potential harms, statin has an overall beneficial effect in patients with previous stroke or TIA. However, more studies are required to investigate the conclusiveness of the increased hemorrhagic stroke risk revealed in our study.
The efficacy of combined use of intraarticular and intravenous tranexamic acid on reducing blood loss and transfusion rate in total knee arthroplasty
Journal of Arthroplasty. 2015;30((5)):776-80.
The purpose of this study is to investigate the effect of preoperative intravenous (IV) and intraoperative topical administration of tranexamic acid (TXA) in total knee arthroplasty (TKA). A total of 120 patients were and randomly allocated to either topical group, combined group, or control group. The mean total blood loss was lower in the combined and topical groups (705mL and 579mL, respectively) in comparison with control group (949mL, P<0.001). There was a significant difference in transfusion rate among groups (P=0.009). The postoperative hemoglobin drop and total drain amount were significantly less in the combined group compared to other groups. In conclusion, combining preoperative IV injection and topical administration of TXA can effectively reduce blood loss and transfusion rate. Copyright © 2014 Elsevier Inc. All rights reserved.
