Background: Early water intake has gained widespread attention considering enhanced recovery after surgery (ERAS). In the present systematic evaluation and meta-analysis, we assessed the effects of early water intake on the incidence of vomiting and aspiration in adult patients who received general anaesthesia on regaining consciousness during the resuscitation period. Objective: To systematically analyse the results of randomised controlled trials on early postoperative water intake in patients who underwent different types of surgery under general anaesthesia, both at home and abroad, to further explore the safety and application of early water intake and provide an evidence-based foundation for clinical application. Design: Systematic review and meta-analysis. Methods: To perform the systematic evaluation and meta-analysis, we searched the Web of Science, CINAHL, Embase, PubMed, Cochrane Library, Sinomed, China National Knowledge Infrastructure (CNKI), Wanfang, and Vipshop databases to identify randomised controlled trial studies on early water intake in adult patients who received general anaesthesia. Results: Herein, we included 10 publications with a total sample size of 5131 patients. Based on statistical analysis, there was no statistically significant difference in the incidence of vomiting (odds ratio [OR] = 0.81; 95% confidence interval [CI] [0.58–1.12]; p = 0.20; I-squared [I2] = 0%) and aspiration (OR = 0.78; 95%CI [0.45–1.37]; p = 0.40; I2 = 0%) between the two groups of patients on regaining consciousness post-general anaesthesia. Conclusion: Based on the available evidence, early water intake after regaining consciousness post-anaesthesia did not increase the incidence of adverse complications when compared with traditional postoperative water abstinence. Early water intake could effectively improve patient thirst and facilitate the recovery of gastrointestinal function. [ABSTRACT FROM AUTHOR]

Loving‐kindness and compassion meditation (LKCM) have been well applied among employees to improve their health and well‐being. Existing studies on LKCM have also provided supportive evidence of its benefits and effectiveness under organizational contexts. The current meta‐analytical study aimed to systematically summarise the effects of LKCM in the workplace and to outline directions for future research and practice. Among 327 empirical studies on LKCM published until March 2022, 21 trials focussed on employees and provided sufficient information, which were included in the following meta‐analysis. The results showed that LKCM benefited eight categories of workplace outcomes. Specifically, LKCM effectively decreased employees' burnout (g = 0.395, k = 10) and stress (g = 0.544, k = 10) and facilitated their mindfulness (g = 0.558, k = 14), self‐compassion (g = 0.646, k = 12), personal mental health (g = 0.308, k = 13), job attitudes (g = 0.283, k = 4), interpersonal relationships (g = 0.381, k = 12), and psychological resources (g = 0.406, k = 6). The results of moderation analyses further indicated that the participants' job type, gender, and the focus of LKCM might differentially fluctuate the magnitude of LKCM effects. To advance research and best practice, we finally pointed out several issues that deserve attention, such as long‐term effects, underlying mechanisms, potential moderators, and outcomes or influential factors at the organizational level.

Aim: To estimate the incidence and identify risk factors of postpartum hemorrhage (PPH) after vaginal delivery. Methods: A systematic review and meta‐analysis was conducted. PubMed, Cochrane Library, CINAHL, Web of Science, EMBASE, and ClinicalTrials.gov databases were systematically searched from inception to April 30th, 2022. Cross‐sectional, cohort, case–control, and secondary analysis of randomized controlled studies that reported the incidence of PPH and the related risk factors in vaginal delivery were eligible through screening of 2343 articles. The incidence, associated standard error, adjusted odds ratios, relative risks and associated 95% confidence intervals were combined in the meta‐analysis. Results: Thirty‐six articles were included in the descriptive review. The incidence of PPH (blood loss ≥500 mL and blood loss ≥1000 mL) was 17% and 6%, respectively. Forty‐one identified risk factors were divided into five categories under two criteria: history and demographics; maternal comorbidity; pregnancy‐related factors; labor‐related factors; delivery‐related factors. Conclusions: With the increasing incidence of PPH globally, obstetric health care providers need to improve their awareness of these multi‐factorial risks to optimize obstetric care and reduce maternal morbidity. This systematic review and meta‐analysis have raised important questions about the nature of vaginal delivery, such as the duration of prolonged labor, details on the use of oxytocin, and the presence of genital tract trauma. There should be highlighted by obstetric personnel on these factors during a patients' labor process. [ABSTRACT FROM AUTHOR]

Background Pharmacological treatments are very common to be used for alleviating neuropsychiatric symptoms (NPS) in dementia. However, decision on drug selection is still a matter of controversy. Aims To summarise the comparative efficacy and acceptability of currently available monotherapy drug regimens for reducing NPS in dementia. Method We searched PubMed, MEDLINE, EMBASE and Cochrane Central Register of Controlled Trials between inception and 26 December 2022 without language restrictions; and reference lists scanned from selected studies and systematic reviews. Double-blind randomised controlled trials were identified from electronic databases for reporting NPS outcomes in people with dementia. Primary outcomes were efficacy and acceptability. Confidence in the evidence was assessed using Confidence in Network Meta-Analysis (CINeMA). Results We included 59 trials (15,781 participants; mean age, 76.6 years) and 15 different drugs in quantitative syntheses. Risperidone (standardised mean difference [SMD] −0.20, 95% credible interval [CrI] −0.40 to −0.10) and galantamine (−0.20, −0.39 to −0.02) were more effective than placebo in short-term treatment (median duration: 12 weeks). Galantamine (odds ratio [OR] 1.95, 95% CrI 1.38–2.94) and rivastigmine (1.87, 1.24–2.99) were associated with more dropouts than placebo, and some active drugs. Most of the results were rated as low or very low according to CINeMA. Conclusions Despite the scarcity of high-quality evidence, risperidone is probably the best pharmacological option to consider for alleviating NPS in people with dementia in short-term treatment when considering the risk–benefit profile of drugs.

Objectives: We performed this meta-analysis to estimate the association between vitamin B6 intake and colorectal cancer risk. Methods: Prospective cohort studies on vitamin B6 intake and colorectal cancer risk were identified by searching databases from the period of 1960 to 2016. Results from individual studies were synthetically combined using Stata 13.0 software. Results: A total of 10 prospective cohort studies including 13 data sets were included in our meta-analysis, containing 7,817 cases and 784,550 subjects. The combined relative risks (RR) of colorectal cancer for the highest vitamin B6 intake compared with the lowest vitamin B6 intake was 0.88 [95% confidence intervals (CIs): 0.77-1.02]. Dose-response meta-analysis based on five eligible studies showed that for each additional 3 and 5 mg of vitamin B6 intake, the risk would decrease by 11% (RR: 0.89, 95%CI: 0.81-0.98) and 17% (RR: 0.83, 95%CI: 0.71-0.97), respectively. Little evidence of publication bias was found. Conclusion: This meta-analysis provides evidence of a nonsignificant decrease in colorectal cancer risk associated with the high level of vitamin B6 intake, but the risk in dose-response analysis is significant. However, the latter finding is based on a limited number of studies, which should be interpreted with caution. [ABSTRACT FROM AUTHOR]
