Objective: To systematically review the safety and efficacy outcomes of using antivirals for the treatment of COVID-19. Methods: Five databases were screened from inception to 27-Aug-2020. The effects of specific drug interventions on safety and efficacy were assessed in COVID-19 patients. Risk Ratios (RRs) with corresponding 95% confidence intervals (CIs) were pooled using random-effects models. Results: A total of 10 studies were identified which fulfill the inclusion criteria. Patients taking antivirals had 26% less risk of having a severe adverse event (SAE) compared to controls (RR, 0.74, CI:0.62 to 0.89, P=0.002). Clinical improvement at day 14 was observed among the cases treated with antivirals compared to the control group (RR 1.24, CI: 1.00 to 1.53 p=0.05). Conclusion: There is evidence that Remdesivir and LPV/r reduces the hospital length of stay and that patients to which antivirals were administered had less SAE and improvement when compared to patients not prescribed with antivirals. Due to a lack of power and the quality of the studies, it was not possible to determine which antivirals have a greater risk-benefit balance, and therefore the optimal approach to antiviral treatment is still uncertain. Keywords: Antiviral agents; COVID-19; SARS-CoV-2; meta-analysis; systematic literature review.

Background: Post-stroke depression is common and it impedes rehabilitation and function recovery after stroke, and numerous trials evaluated SSRI’s for depression prophylaxis. The objective of this study is to assess the use of SSRI for prevention of poststroke depression and the potential effect on functional recovery after stroke. Methods: We searched electronic databases up to July 2019 for randomized controlled trials of SSRI’s for patients with stroke versus placebo. We calculated pooled odds ratios and 95% CIs by using random-effects models. The primary end points were depression and good functional outcome (modified Rankin Scale score of 0-2) at 90 days post-randomization. We followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Results: Twelve randomized control trials assessing 4,887 patients have been included in the meta-analysis. SSRI treatment after stroke decreased the odds of depression compared to control group (OR = 0.48, 95% CI - 0.30 to 0.78, p=0.003). There was no heterogeneity between the trials (Cochran’s Q statistic 4.623, df 5; P = .337, I 2 =5.626%). The proportion of subjects who achieved mRS 0-2 at 90 days was similar between SSRI and control groups (OR= 3.471, 95% CI - 0.59 to 20.38, p=0.168). Conclusion: SSRI treatment for the stroke patients reduces the incidence of depression but it does not increase the odds of good functional recovery.

Abstracts Prepulse inhibition (PPI) of startle is an operational measure of sensorimotor gating that is often impaired in patients with schizophrenia. Despite the large number of studies, there is considerable variation in PPI outcomes reported. We conducted a systematic review and meta-analysis investigating PPI impairment in patients with schizophrenia compared with healthy control subjects, and examined possible explanations for the variation in results between studies. Major databases were screened for observational studies comparing healthy subjects and patients with schizophrenia for the prepulse and pulse intervals of 60 and 120 ms as primary outcomes, ie, PPI-60 and PPI-120. Standardized mean difference (SMD) and 95% confidence intervals (CI) were extracted and pooled using random effects models. We then estimated the mean effect size of these measures with random effects meta-analyses and evaluated potential PPI heterogeneity moderators, using sensitivity analysis and meta-regressions. Sixty-seven primary studies were identified, with 3685 healthy and 4290 patients with schizophrenia. The schizophrenia group showed reduction in sensorimotor gating for both PPI-60 (SMD = −0.50, 95% CI = [−0.61, −0.39]) and PPI-120 (SMD = −0.44, 95% CI = [−0.54, −0.33]). The sensitivity and meta-regression analysis showed that sample size, gender proportion, imbalance for gender, source of control group, and study continent were sources of heterogeneity (P < .05) for both PPI-60 and PPI-120 outcomes. Our findings confirm a global sensorimotor gating deficit in schizophrenia patients, with overall moderate effect size for PPI-60 and PPI-120. Methodological consistency should decrease the high level of heterogeneity of PPI results between studies.

Abstract Exposure to per- and polyfluoroalkyl substances (PFAS), ubiquitous persistent environmental contaminants, has led to substantial global concern due to their potential environmental and human health effects. Several epidemiological studies have assessed the possible association between PFAS exposure and risk of metabolic syndrome (MetS), however, the results are ambiguous. The aim of this study was to assess the current human epidemiologic evidence on the association between exposure to PFAS and MetS. We performed a systematic search strategy using three electronic databases (PubMed, Scopus, and Web of Science) for relevant studies concerning the associations of PFAS with MetS and its clinical relevance from inception until January 2021. We undertook meta-analyses where there were five or more studies with exposure and outcomes assessments that were reasonably comparable. The pooled odd ratios (ORs) were calculated using random effects models and heterogeneity among studies was assessed by I2 index and Q test. A total of 12 cross-sectional studies (10 studies on the general population and two studies in the occupational settings) investigated the association between PFAS exposure and MetS. We pooled data from seven studies on the general population for perfluorooctanoic acid (PFOA) and perfluorooctanesulfonate (PFOS) and five studies for perfluorohexanesulfonate (PFHxS) and perfluorononanoic acid (PFNA). Predominately, most studies reported no statistically significant association between concentrations of PFAS and MetS. In the meta-analysis, the overall measure of effect was not statistically significant, showing no evidence of an association between concentrations of PFOA, PFOS, PFNA, and PFHxS and the risk of MetS. Based on the results of the meta-analysis, current small body of evidence does not support association between PFAS and MetS. However, due to limited number of studies and substantial heterogeneity, results should be interpreted with caution. Further scrutinizing cohort studies are needed to evaluate the association between various and less well-known PFAS substances and their mixture with MetS and its components in both adults and children in different settings.

ObjectivesPrevious studies have reported beneficial effects of perioperative music on patients’ anxiety and pain. We performed a systematic review and meta-analysis of randomised controlled trials investigating music interventions in cardiac surgery.MethodsFive electronic databases were systematically searched. Primary outcomes were patients’ postoperative anxiety and pain. Secondary outcomes were hospital length of stay, opioid use, vital parameters and time on mechanical ventilation. PRISMA guidelines were followed and PROSPERO database registration was completed (CRD42020149733). A meta-analysis was performed using random effects models and pooled standardised mean differences (SMD) with 95% confidence intervals were calculated.ResultsTwenty studies were included for qualitative analysis (1169 patients) and 16 (987 patients) for meta-analysis. The first postoperative music session was associated with significantly reduced postoperative anxiety (SMD = –0.50 (95% CI –0.67 to –0.32), p<0.01) and pain (SMD = –0.51 (95% CI –0.84 to –0.19), p<0.01). This is equal to a reduction of 4.00 points (95% CI 2.56 to 5.36) and 1.05 points (95% CI 0.67 to 1.41) on the State-Trait Anxiety Inventory and Visual Analogue Scale (VAS)/Numeric Rating Scale (NRS), respectively, for anxiety, and 1.26 points (95% CI 0.47 to 2.07) on the VAS/NRS for pain. Multiple days of music intervention reduced anxiety until 8 days postoperatively (SMD = –0.39 (95% CI –0.64 to –0.15), p<0.01).ConclusionsOffering recorded music is associated with a significant reduction in postoperative anxiety and pain in cardiac surgery. Unlike pharmacological interventions, music is without side effects so is promising in this population.

Background: This study systematically evaluated the safety and efficacy of dexmedetomidine for procedural sedation and postoperative behaviors in a pediatric population as well as whether the results met the information required to draw conclusions. Objective: To evaluate the safety and efficacy evaluation of dexmedetomidine for procedural sedation and postoperative behaviors in a pediatric population. Methods: PubMed, Cochrane library, Web of Science and Ovid MEDLINE were searched to obtain randomized controlled trials (RCTs) comparing dexmedetomidine with control medicine and comparing different doses of dexmedetomidine. Results: There were a total of 16 RCTs for a total of 3240 patients. Dexmedetomidine slowed down the heart rate (HR; mean difference: −13.27; 95% CI: −16.41 to 10.14; P < 0.001) and reduced postoperative delirium (risk ratio [RR]: 0.31; 95% CI: 0.20-0.50; P < 0.001), the number of pain patients (RR: 0.48; 95% CI: 0.30-0.75; P = 0.002), and desaturation (RR: 0.34; 95% CI: 0.13-0.89; P = 0.03) compared with the control group. The limitation was that it was difficult to determine the range of low- and high-dose dexmedetomidine. Conclusion and Relevance: Dexmedetomidine slowed down intraoperative HR within the normal range, which might reduce myocardial oxygen consumption. It reduced postoperative pain and postoperative complications: delirium and desaturation. Dexmedetomidine showed no dose-dependent increase in the procedural sedation time of pediatric patients. Clinically, dexmedetomidine can improve pediatric procedural sedation and postoperative behavior, and it can be considered as a related medicine for safety in pediatric surgery.

Background: Acute kidney injury (AKI) requiring kidney replacement therapy (KRT) is associated with high mortality and utilization. We evaluated the use of an AKI-Standardized Clinical Assessment and Management Plan (SCAMP) on patient outcomes including mortality, hospital and ICU length of stay. Methods: We conducted a 12-month controlled study in the ICUs of a large academic tertiary medical center. We alternated use of the AKI-SCAMP with use of a "sham" control form in 4-6-week blocks. The primary outcome was risk of inpatient mortality. Pre-specified secondary outcomes included 30-day mortality, 60-day mortality and hospital and ICU length of stay. Generalized estimating equations were used to estimate the impact of the AKI-SCAMP on mortality and length of stay. Results: There were 122 patients in the AKI-SCAMP group and 102 patients in the control group. There was no significant difference in inpatient mortality associated with AKI-SCAMP use (41% vs 47% control). AKI-SCAMP use was associated with significantly reduced ICU length of stay (mean 8 (95% CI 8-9) vs 12 (95% CI 10-13) days; p = <0.0001) and hospital length of stay (mean 25 (95% CI 22-29) vs 30 (95% CI 27-34) days; p = 0.02). Patients in the AKI-SCAMP group less likely to receive KRT in the context of physician-perceived treatment futility than those in the control group (2% vs 7%, p=0.003). Conclusions: Use of the AKI-SCAMP tool for AKI-KRT was not significantly associated with inpatient mortality but was associated with reduced ICU and hospital length of stay and use of KRT in cases of physician-perceived treatment futility.

Abstract Background In areas where Lyme disease is endemic, bites from ticks are common, but no vaccine is currently available against Lyme disease for humans. Therefore, the feasibility of using antibiotic prophylaxis to prevent Lyme disease after a tick bite is worth further exploration. Previous meta-analyses lack sufficient power to demonstrate the efficacy of about antibiotic prophylaxis for the prevention of Lyme disease following a tick bite. In this study, we explored more precise evidence and attempted to identify and update optimum treatment strategies. Methods We searched PubMed, Embase, and the Cochrane Library for studies until March 23, 2021. We included studies if the enrolled patients were randomly allocated to a treatment or control group within 72 h following a tick bite and had no clinical evidence of Lyme disease at enrolment. The Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) reporting guidelines were followed for data abstraction. Two authors (GZZ and XX) independently reviewed the abstracts and identified articles for detailed assessment. We used a random-effects model to calculate the pooled results and reported the 95% confidence interval (CI). Study quality was assessed using a modified Jadad scale, and publication bias was assessed using Egger’s test. We calculated the risk ratio (RR) for the rates of unfavorable events in patients who received intervention versus the control group. This study is registered with PROSPERO, number CRD42021245002. Results Six studies (3,766 individuals) were included. The pooled rate of unfavorable events in persons receiving treatment and the control group were 0.4% (95%CI: 0.1–1.1%) and 2.2% (95%CI: 1.6–3.0%), respectively. The pooled RR was 0.38 (95%CI: 0.22–0.66). Subgroup analysis revealed that the pooled RR was 0.29 (95%CI: 0.14–0.60) in the single-use 200-mg doxycycline group; 0.28 (95%CI: 0.05–1.67) in a 10-day course group (Amoxicillin, Penicillin or tetracycline); and 0.73 (95%CI: 0.25–2.08) in a topical antibiotic treatment group (Azithromycin). Conclusions The available evidence supports the use of antibiotics for the prevention of Lyme disease, and reveals advantages of using single-dose; however, further confirmation is needed.

Abstract Background Leishmaniasis is one of the most important health problems worldwide. The evidence has suggested that resveratrol and its derivatives have anti-leishmanial effects; however, the results are inconsistent and inconclusive. The aim of this study was to assess the effect of resveratrol and its derivatives on the Leishmania viability through a systematic review and meta-analysis of available relevant studies. Methods The electronic databases PubMed, ScienceDirect, Embase, Web of Science and Scopus were queried between October 2000 and April 2020 using a comprehensive search strategy. The eligible articles selected and data extraction conducted by two reviewers. Mean differences of IC50 (concentration leading to reduction of 50% of Leishmania) for each outcome was calculated using random-effects models. Sensitivity analyses and prespecified subgroup were conducted to evaluate potential heterogeneity and the stability of the pooled results. Publication bias was evaluated using the Egger’s and Begg’s tests. We also followed the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines for this review. Results Ten studies were included in the meta-analysis. We observed that RSV and its derivatives had significant reducing effects on Leishmania viability in promastigote [24.02 µg/ml; (95% CI 17.1, 30.8); P < 0.05; I2 = 99.8%; P heterogeneity = 0.00] and amastigote [18.3 µg/ml; (95% CI 13.5, 23.2); P < 0.05; I2 = 99.6%; P heterogeneity = 0.00] stages of Leishmania. A significant publication bias was observed in the meta-analysis. Sensitivity analyses showed a similar effect size while reducing the heterogeneity. Subgroup analysis indicated that the pooled effects of leishmanicidal of resveratrol and its derivatives were affected by type of stilbenes and Leishmania species. Conclusions Our findings clearly suggest that the strategies for the treatment of leishmaniasis should be focused on natural products such as RSV and its derivatives. Further study is needed to identify the mechanisms mediating this protective effects of RSV and its derivatives in leishmaniasis.

This study aimed to assess current evidence regarding the effect of selenium (Se) supplementation on the prognosis in patients sustaining trauma. MEDLINE, Embase, and Web of Science databases were searched with the following terms: “trace element”, “selenium”, “copper”, “zinc”, “injury”, and “trauma”. Seven studies were included in the meta-analysis. The pooled results showed that Se supplementation was associated with a lower mortality rate (OR 0.733, 95% CI: 0.586, 0.918, p = 0.007; heterogeneity, I2 = 0%). Regarding the incidence of infectious complications, there was no statistically significant benefit after analyzing the four studies (OR 0.942, 95% CI: 0.695, 1.277, p = 0.702; heterogeneity, I2 = 14.343%). The patients with Se supplementation had a reduced ICU length of stay (standard difference in means (SMD): −0.324, 95% CI: −0.382, −0.265, p < 0.001; heterogeneity, I2 = 0%) and lesser hospital length of stay (SMD: −0.243, 95% CI: −0.474, −0.012, p < 0.001; heterogeneity, I2 = 45.496%). Se supplementation after trauma confers positive effects in decreasing the mortality and length of ICU and hospital stay.

This study aims to evaluate the effectiveness of the use of antibiotic prophylaxis in cesarean section at Thai Nguyen National Hospital as a first pilot activity of a surgical prophylaxis program. In the study, a randomized controlled trial was designed with two groups: intervention group and control group. Patients characteristics and effectiveness of prophylactic antibiotics for caesarean section were compared. The study results show that the patients’ ages ranged from 18 to 44 years; most of the patients had ASA score of 1; and mean hospital length of stay was statistically significant between the two groups (p<0.05). Regarding the indication of caesarean section, the reason of genital tract abnormalities accounted for the highest proportion. The percentage of the patients switching from prophylactic antibiotic regimens to therapeutic antibiotics in the intervention group was 2%. There was no patient with superficial and/or deep incisional surgical site infections in both groups. The difference in mean number of injections in the two groups was statistically significant (p<0.05). The average cost of antibiotics for each patient in the intervention group and control group were 267.720 VND and 543.871 VND, respectively. The study concludes that the effectiveness of antibiotics prophylaxis for caesarean section: 99% of the patients were without wound infection; hospital length of stay in the intervention group was shorter than the control group; and using prophylactic antibiotics was not only more economical but could also reduce the workload of medical staff, costs of antibiotics and medical supplies.
