Introduction Infection after stroke is associated with unfavorable outcome. Randomized controlled studies did not show benefit of preventive antibiotics in stroke but lacked power for subgroup analyses. Aim of this study is to assess whether preventive antibiotic therapy after stroke improves functional outcome for specific patient groups in an individual patient data meta-analysis. Patients and methods We searched MEDLINE (1946–7 May 2021), Embase (1947–7 May 2021), CENTRAL (17th September 2021), trial registries, cross-checked references and contacted researchers for randomized controlled trials of preventive antibiotic therapy versus placebo or standard care in ischemic or hemorrhagic stroke patients. Meta-analysis was performed by a one-step and two-step approach. Primary outcome was functional outcome adjusted for age and stroke severity. Secondary outcomes were infections and mortality. Results 4197 patients from nine trials were included. Preventive antibiotic therapy was not associated with a shift in functional outcome (mRS) at 3 months (OR1.13, 95%CI 0.98–1.31) or unfavorable functional outcome (mRS 3–6) (OR0.85, 95%CI 0.60–1.19). Preventive antibiotics did not improve functional outcome in pre-defined subgroups (age, stroke severity, timing and type of antibiotic therapy, pneumonia prediction scores, dysphagia, type of stroke, and type of trial). Preventive antibiotics reduced infections (276/2066 (13.4%) in the preventive antibiotic group vs. 417/2059 (20.3%) in the control group, OR 0.60, 95% CI 0.51–0.71, p < 0.001), but not pneumonia (191/2066 (9.2%) in the preventive antibiotic group vs. 205/2061 (9.9%) in the control group (OR 0.92 (0.75–1.14), p = 0.450). Discussion and conclusion Preventive antibiotic therapy did not benefit any subgroup of patients with acute stroke and currently cannot be recommended.

Abstract Background: Although multiple randomized controlled trials (RCTs) and meta-analyses have been conducted on the issue of acute phase anti-hypertensive therapies for ischemic stroke (IS) patients, many studies have failed to enhance blood pressure (BP) decrease after these treatments. The effects of effective acute anti-hypertensive therapies on IS prognosis are still unclear.Methods: Published literature was systematically searched in PubMed, Embase and Cochrane Library. Multiple RCTs that included IS patients, in which there was a significant BP decrease in the anti-hypertensive intervention group compared with the control group within 72 h after the onset of stroke, were identified. A meta-analysis was conducted to assess the effects of such therapy on the functional outcome, mortality, and multiple severe adverse events (SAEs) of IS patients.Results: Eight RCTs were included in this study, with a total of 9427 IS patients. According to this meta-analysis, with significant BP differences between the treatment and control groups within 72 h from stroke onset, effective acute anti-hypertensive therapy has a neutral effect on multiple IS prognostic factors, including functional outcome (RR 1.03, 95% CI 0.93-1.13), mortality (RR 1.10, 95% CI 0.89-1.35), and multiple SAEs.Conclusions: Based on current studies, effective acute anti-hypertensive therapy did not improve the prognosis of IS patients, including functional outcome, mortality, and SAEs. There is no evidence that such therapy is beneficial in clinical practice.

Purpose. This meta-analysis is to assess the effectiveness of teriparatide in fracture healing and clinical function improvement of the osteoporotic patients. Methods. We searched PubMed, Embase, Web of Science, and the Cochrane databases for randomized and quasi-randomized controlled trials comparing teriparatide to placebo, no treatment, or comparator interventions in the osteoporotic patients. Results. Five studies with 251 patients were included. Patients treated with teriparatide therapy had a significant shorter radiological fracture healing time compared with those in the control group (mean difference [MD] −4.54 days, 95% confidence interval [CI] −8.80 to −0.28). Stratified analysis showed that lower limb group had significant shorter healing time (MD −6.24 days, 95% CI −7.20 to −5.29), but upper limb group did not (MD −1 days, 95% CI −2.02 to 0.2). Patients treated with teriparatide therapy showed better functional outcome than those in the control group (standardized mean difference [SMD] −1.02, 95% CI −1.81 to −0.22). Patients with therapy duration over 4 weeks would have better functional outcome (SMD −1.68, 95% CI −2.07 to −1.29). Conclusions. Teriparatide is effective in accelerating fracture healing and improving functional outcome of osteoporotic women. However, more clinical studies are warranted in order to determine whether the results are applicable to males and the clinical indications for teriparatide after osteoporotic fractures.

Background: Dysphagia is common after stroke and associated with a poor outcome. Pharyngeal electrical stimulation (PES) increased decannulation rates in tracheotomised stroke patients with dysphagia following ventilation in two trials. We report the results of an individual patient data meta-analysis assessing PES in severely dysphagic tracheotomised stroke patients. Methods: We searched for randomised controlled trials of PES in dysphagic tracheotomised stroke patients and obtained individual patient data for demographic and clinical (stroke severity, NIHSS; functional oral intake scale, FOIS; decannulation) variables from trialists. Data are number (%), median [interquartile range], mean (standard deviation) and mean difference (MD) or odds ratio (OR) with 95% confidence intervals (CI). Results: Two completed trials were identified (n=30, PHAST-TRAC n=69 [funded by Phagenesis Ltd]), with data for 99 participants (PES 55, 56%; sham 44, 44%). Mean age 64 (13) years, female 40 (40%), NIHSS 18 [14-21], time from onset to randomisation 27 days [20-38], and FOIS=1 (nil by mouth). As compared with sham, PES was associated with an increased proportion of patients who were ready for early decannulation, 59% versus 11% (OR 11.4, 95% CI 3.86-33.33; p<0.001) and improved FOIS score at discharge (MD 1.13, 95% CI 0.25-2.00; p=0.011). Treated participants who were ready for decannulation tended to have a shorter hospital length of stay: 23 vs 41 days (p=0.070) than those who were not ready. No device-related serious adverse events were reported. Conclusions: PES was associated with an increased proportion of stroke patients who were ready for decannulation and less dysphagia, in two randomised trials.

Abstract Background Usefulness of noninvasive ventilation (NIV) in weaning patients with non-hypercapnic hypoxemic acute respiratory failure (hARF) is unclear. The study aims to assess in patients with non-hypercapnic hARF, the efficacy of NIV after early extubation, compared to standard weaning. Methods In this individual patient data meta-analysis, we searched EMBASE, Medline and Cochrane Central Register of Controlled Trials to identify potentially eligible randomized controlled trials published from database inception to October 2020. To be eligible, studies had to include patients treated with NIV after early extubation and compared to conventional weaning in adult non-hypercapnic hARF patients. Anonymized individual patient data from eligible studies were provided by study investigators. Using one-step and two-step meta-analysis models we tested the difference in total days spent on invasive ventilation. Results We screened 1605 records. Six studies were included in quantitative synthesis. Overall, 459 participants (mean [SD] age, 62 [15] years; 269 [59%] males) recovering from hARF were included in the analysis (233 in the intervention group and 226 controls). Participants receiving NIV had a shorter duration of invasive mechanical ventilation compared to control group (mean difference, − 3.43; 95% CI − 5.17 to − 1.69 days, p < 0.001), a shorter duration of total days spent on mechanical ventilation (mean difference, − 2.04; 95% CI − 3.82 to − 0.27 days, p = 0.024), a reduced risk of ventilatory associated pneumonia (odds ratio, 0.24; 95% CI 0.08 to 0.71, p = 0.014), a reduction of time spent in ICU (time ratio, 0.81; 95% CI 0.68 to 0.96, p = 0.015) and in-hospital (time ratio, 0.81; 95% CI 0.69 to 0.95, p = 0.010), with no difference in ICU mortality. Conclusions Although primary studies are limited, using an individual patient data metanalysis approach, NIV after early extubation appears useful in reducing total days spent on invasive mechanical ventilation. Trial registration The protocol was registered to PROSPERO database on 12/06/2019 and available at PROSPERO website inserting the study code i.e., CRD42019133837.

Purpose. To use the meta-analytic approach to examine the effects of diet (D), aerobic exercise (E), or both (DE) on non-high-density lipoprotein cholesterol (non-HDL-C) in adults. Methods. Randomized controlled trials in adults ≥18 years of age were included. A mixed-effect model was used to combine effect size (ES) results within each subgroup and to compare subgroups (Qb). Heterogeneity was examined using the Q and I2 statistics, and 95% confidence intervals (CI) were also calculated. Statistical significance was set at P≤0.05, while a trend for statistical significance was set between P>0.05, and ≤0.10. Results. A statistically significant exercise minus control group decrease in non-HDL-C was found for DE (7 ESs, 389 participants, x¯=-11.1 mg/dL, 95%  CI=−21.7 to −0.6, P=0.04, Q=2.4, P=0.88, I2=0%), a trend for the D group (7 ESs, 402 participants, x¯=−8.5 mg/dL, 95%  CI=−18.6 to 1.6, P=0.10, Q=0.76, P=0.99, I2=0%), and no change for the E group (7 ESs, 387 participants, x¯=3.0 mg/dL, 95%   CI=−7.1 to 13.1, P=0.56, Q=0.78, P=0.99, I2=0%). Overall, no statistically significant between-group differences were found (Qb=4.1, P=0.12). Conclusions. Diet combined with aerobic exercise may reduce non-HDL-C among adults in some settings.

Virtual reality (VR), a technology that provides a stimulated sensory experience, has recently been implemented in various fields of medicine. Several studies have investigated the efficacy of VR on preoperative anxiety. The purpose of this meta-analysis was to validate whether VR could relieve preoperative anxiety in patients undergoing surgery. Electronic databases were searched to identify all randomized controlled trials (RCTs) investigating the effect of VR on preoperative anxiety. The primary outcome was defined as the preoperative anxiety scores. We estimated the effect size using the standard mean difference (SMD) with a 95% confidence interval (CI) using a random effect model. Ultimately, 10 RCTs, with a total of 813 patients, were included in the final analysis. Preoperative anxiety was significantly lower in the VR group than in the control group (SMD −0.64, 95% CI −1.08 to −0.20, p = 0.004). In a subgroup analysis, the preoperative anxiety scores were lower in the VR group than in the control group in pediatric patients (SMD −0.71, 95% CI −1.14 to −0.27, p = 0.002), whereas a significant difference was not observed between the two groups in adult patients (p = 0.226). The results of this meta-analysis indicated that VR could decrease preoperative anxiety, especially in pediatric patients.

Abstract Objectives This meta-analysis aimed to evaluate the efficacy and safety of antimuscarinics for the prevention or treatment of catheter related bladder discomfort (CRBD). Methods The MEDLINE, EMBASE, and Cochrane Controlled Trials Register (from 1987 to July 2021) were used to search randomized controlled trials. The PRISMA checklists were followed. RevMan5.4.0 was used for statistical analysis. Results Eleven studies involving 1165 patients were involved in the analysis. The study reported that the incidence of CRBD observed in the antimuscarinics group was significantly lower than that of the control group at 0-, 1-, 2-, and 6-h after drug therapy (P = 0.001, P < 0.0001, P = 0.0005, and P = 0.001, respectively). For side effects, there were not statistical differences between the antimuscarinics group and the control group, mainly including dry mouth (risk ratio (RR) = 1.31, 95% confidence interval (CI) = 0.95 to 1.80, P = 0.09), postoperative nausea and vomiting (RR = 1.02, 95% CI = 0.55 to 1.90, P = 0.87), facial flushing (RR = 1.06, 95% CI = 0.43 to 2.61, P = 0.90), and blurred vision (RR = 0.95, 95% CI = 0.35 to 2.58, P = 0.91). Besides, rescue analgesics were required less in the antimuscarinics group than in the control group (RR = 0.51, 95% CI = 0.32 to 0.80, P = 0.003). Conclusions Compared with the control group, the antimuscarinics group had a significant improvement on CRBD, the patients were well tolerated and the use rate of rescue analgesics was low.
