Long-Acting Injectable Second-Generation Antipsychotics vs Placebo and Their Oral Formulations in Acute Schizophrenia: A Systematic Review and Meta-Analysis of Randomized-Controlled-Trials.
BACKGROUND AND HYPOTHESIS
Long-acting injectable antipsychotic drugs (LAIs) are mainly used for relapse prevention but could also be advantageous for acutely ill patients with schizophrenia.
STUDY DESIGN
We conducted a systematic review and meta-analysis of randomized-controlled-trials (RCTs) comparing the second-generation long-acting injectable antipsychotics (SGA-LAIs) olanzapine, risperidone, paliperidone, and aripiprazole with placebo or their oral counterparts in acutely ill patients with schizophrenia. We analyzed 23 efficacy and tolerability outcomes, with the primary outcome being overall symptoms of schizophrenia. The results were obtained through random effects, pairwise meta-analyses, and subgroup tests. The study quality was assessed using the Cochrane-Risk-of-Bias-Tool version-1.
STUDY RESULTS
Sixty-six studies with 16 457 participants were included in the analysis. Eleven studies compared second-generation long-acting injectable antipsychotics (SGA-LAIs) with a placebo, 54 compared second-generation oral antipsychotics (SGA-orals) with a placebo, and one compared an SGA-LAI (aripiprazole) with its oral formulation. All 4 SGA-LAIs reduced overall symptoms more than placebo, with mean standardized differences of -0.66 (95% CI: -0.90; -0.43) for olanzapine, -0.64 (-0.80; -0.48) for aripiprazole, -0.62 (-0.76; -0.48) for risperidone and -0.42 (-0.53; -0.31) for paliperidone. The side-effect profiles of the LAIs corresponded to the patterns known from the oral formulations. In subgroup tests compared to placebo, some side effects were less pronounced under LAIs than under their oral formulations.
CONCLUSIONS
SGA-LAIs effectively treat acute schizophrenia. Some side effects may be less frequent than under oral drugs, but due to the indirect nature of the comparisons, this finding must be confirmed by RCTs comparing LAIs and orals head-to-head.

Meta-Analysis
Intermediate- to high-dose dexamethasone versus low-dose dexamethasone in patients with COVID-19 requiring respiratory support: a systematic review and meta-analysis of randomized trials.
The present review critically appraised the randomized clinical trials that compared mortality outcomes between intermediate- to high-dose dexamethasone and low-dose dexamethasonein patients with COVID-19 and reported pooled mortality risk estimates associated with these two dosing regimens of dexamethasone. The systematic searching of electronic databases was limited to randomized clinical trials that compared mortality outcomes between intermediate- to high-dose dexamethasone with low-dose dexamethasone in patients with COVID-19 requiring respiratory support. The primary outcome of interest in this review was all-cause mortality. A total of eight trials with 1800 patients randomized to receive intermediate to high-dose dexamethasone and 1715 patients randomized to low-dose dexamethasone were included. The meta-analysis of six trials revealed no significant difference in the risk of 28-day all-cause mortality between intermediate- to high-dose dexamethasone and low-dose dexamethasone (odds ratio 1.16, 95% confidence interval, 0.77-1.74). Similarly, the meta-analysis of five trials revealed no significant difference between the two doses regarding 60-day all-cause mortality (odds ratio 0.96, 95% confidence interval 0.74-1.26). The results suggest intermediate- to high-dose dexamethasone to be as effective as low-dose dexamethasone in reducing the risk of mortality among patients with COVID-19 requiring respiratory support. However, higher dexamethasone doses could expose patients with COVID-19 to an increased risk of adverse events, such as hyperglycemia.

Review
PURPOSE
Post-pericardiotomy syndrome (PPS) is a common complication of cardiac surgery. This systematic review aimed to investigate the efficacy of colchicine, indomethacin, and dexamethasone in the treatment and prophylaxis of PPS.
METHODS
Literature research was carried out using PubMed. Studies investigating ≥ 10 patients with clinically PPS treated with colchicine, dexamethasone, and indomethacin and compared with placebo were included. Animal or in vitro experiments, studies on < 10 patients, case reports, congress reports, and review articles were excluded. Cochrane risk-of-bias tool for randomized trials (RoB2) was used for the quality assessment of studies.
RESULTS
Seven studies were included. Among studies with postoperative colchicine treatment, two of them demonstrated a significant reduction of PPS. In the single pre-surgery colchicine administration study, a decrease of PPS cases was registered. Indomethacin pre-surgery administration was linked to a reduction of PPS. No significant result emerged with preoperative dexamethasone intake.
CONCLUSION
Better outcomes have been registered when colchicine and indomethacin were administered as primary prophylactic agents in preventing PPS and PE. Further RCT studies are needed to confirm these results.
