Purpose of Review: The combination of ketamine with propofol and dexmedetomidine has gained popularity for sedation and general anesthesia in different populations. In our meta-nalysis, we helped the anesthesiologists to know the efficiency and the efficacy of both combinations in adult and pediatric patients. Methods: We searched PubMed, CENTRAL, Web of Science, and Scopus from inception to August 1, 2023. Our outcome parameters for efficacy were recovery time, pain score, and physician satisfaction while for safety were the related cardiorespiratory, neurological, and gastrointestinal adverse events. Recent Findings: Twenty-two trials were included with a total of 1429 patients. We found a significantly longer recovery time in the ketadex group of 7.59 min (95% CI, 4.92, 10.26; I² = 94%) and a significantly less pain score of − 0.72 (95% CI, − 1.10, − 0.34; I² = 0%). Adults had a significantly better physician satisfaction score with the ketofol group, odds ratio of 0.29 (95% CI, 0.12, 0.71; I² = 0%). Recovery agitations were higher in the ketofol group with an odds ratio of 0.48 (95% CI, 0.24, 0.98; I² = 36%). Furthermore, we found a significant difference between the combinations with a higher incidence in the ketadex group with pooled odds ratio of 1.75 (95% CI, 1.06, 2.88; I² = 15%). Summary: Ketadex was associated with lower pain scores, hypoxic events and airway obstruction, and emergence agitation. At the same time, ketofol had much more clinician satisfaction which might be attributed to the shorter recovery time and lower incidence of nausea and vomiting. Therefore, we suppose that ketadex is the better combination in periprocedural sedation for both adult and pediatric patients who are not at greater risk for postoperative nausea and vomiting.

Background Intermittent ambulatory levosimendan administration has been shown in several small randomized controlled trials to benefit patients with advanced heart failure, preventing heart failure rehospitalization and mortality. We aim to investigate the totality of high-quality evidence regarding the efficacy and safety of intermittent levosimendan in advanced heart failure patients. Methods Up to September 2023, we systematically reviewed the randomized controlled trials indexed in PubMed, Embase Cochrane, SCOPUS, and Web of Science. We used mean difference (MD) to estimate the continuous outcomes, and risk ratio (RR) for the dichotomous outcomes with a 95% confidence interval (CI), using the random-effects model. Ultimately, a trial sequential analysis was employed to enhance the reliability of our findings and Grading of Recommendations Assessment, Development, and Evaluation (GRADE) framework for certainty leveling. Results Fifteen randomized controlled trials with 1181 patients were included. Intermittent levosimendan was significantly associated with an improved left ventricular ejection fraction compared with placebo (MD 6.39 [95% CI 3.04–9.73], P = 0.002; I² = 75, P = 0.0005), with cumulative z-score of change after ≤ 1 week passing the monitoring boundaries, favoring the levosimendan, but did not cross the required information size. Additionally, levosimendan reduced the all-cause mortality rate (RR 0.60 [95% CI 0.40–0.90], P = 0.01; I² = 9, P = 0.36). However, we found no difference between levosimendan and placebo in all-cause rehospitalization rate (RR 0.75 [95% CI 0.46–1.22], P = 0.25; I² = 70, P = 0.04), event-free survival rate (RR 0.97 [95% CI 0.72–1.30], P = 0.84; I² = 63, P = 0.03), or any adverse event (RR 1 [95% CI 0.73–1.37], P = 1.00, I² = 0%, P = 0.70). Conclusion In patients with advanced heart failure, intermittent levosimendan significantly improved left ventricular ejection fraction, brain natriuretic peptide values, and all-cause mortality rate. Levosimendan use is not associated with a change in rehospitalization or event-free survival. Registration PROSPERO identifier number (CRD42023487838).

Introduction: Magnesium sulfate is the most utilized anticonvulsant for treating patients with eclampsia and pre-eclampsia. The purpose of this study is to determine whether the 12-h regimen of magnesium sulfate outweighs the 24-h regimen in both efficacy and safety in the management of patients with mild or severe pre-eclampsia and eclampsia. Methods: We searched six electronic databases: PubMed, Scopus, Web of Science, Cochrane Library, Ovid, and Google Scholar. This search was conducted to yield any studies that were published until 15 January 2023. We did the statistical analysis plan by Review Manager Software version 5.4. Results: We included 13 randomized control trials with 2813 patients in this systematic review. Our meta-analysis revealed that there were no statistically significant differences between the 12-h regimen of the magnesium sulfate group and the 24-h regimen of the magnesium sulfate group in our outcome of interest: occurrence of seizure (RD: -0.00, 95% CI [-0.01, 0.00], P = 0.56), diminished deep tendon reflexes (RD: -0.00, 95% CI [-0.01, 0.01], P = 0.80), respiratory depression (RD: -0.00, 95% CI [-0.02, 0.01], P = 0.57), and pulmonary edema (RD: -0.00, 95% CI [-0.01, 0.01], P = 0.85). Conclusion: Our study showed no statistically significant difference in effectiveness and toxicity risk between the 12-h and 24-h regimens.

Background: Monkeypox is a zoonotic viral infection first reported in May 2022. Monkeypox cases present with prodromal symptoms, rash, and/or systemic complications. This study systematically reviews the monkeypox cases presented with any cardiac complications. Methods: A systematic literature search was done to locate papers that discuss any cardiac complications associated with monkeypox; then, data were analyzed qualitatively. Results: Nine articles, including the 13 cases that reported cardiac complications of the disease, were included in the review. Five cases previously had sex with men, and two cases had unprotected intercourse, which reveals the importance of the sexual route in disease transmission. All cases have a wide spectrum of cardiac complications, such as acute myocarditis, pericarditis, pericardial effusion, and myopericarditis. Conclusion: This study clarifies the potential for cardiac complications in monkeypox cases and provides avenues for future research to determine the underlying mechanism. Also, we found that the cases with pericarditis were treated with colchicine, and those with myocarditis were treated with supportive care or cardioprotective treatment (Bisoprolol and Ramipril). Furthermore, Tecovirimat is used as an antiviral drug for 14 days.

Background Iron deficiency is prevalent among heart failure patients and is associated with worse clinical outcomes, including decreased quality of life and functional capacity. This condition often results in a higher incidence of hospitalization and mortality. Iron supplementation, particularly with intravenous ferric carboxymaltose (FCM), has shown potential benefits as an adjunct therapy in heart failure management. This study aims to evaluate the efficacy of FCM in the treatment of patients with heart failure and iron deficiency anemia, with a focus on its impact on mortality and hospitalization rates. Methods A comprehensive search was conducted in PubMed, Web of Science, and Scopus databases from their inception until 1st December 2023. Meta-analysis was performed using RevMan 5.4, employing a random-model effect. The results were reported as risk ratios (RRs), standard mean differences (SMDs), and 95 % confidence intervals (CIs). Results The meta-analysis included 13 studies with a total of 6271 patients. Ferric carboxymaltose administration resulted in a significant improvement in the 6-minute walk distance (SMD: 1.45; 95 % CI: 0.55, 2.36; p = 0.002), quality of life, as assessed by the Kansas City Cardiomyopathy Questionnaire (KCCQ) (SMD: 1.49; 95 % CI: 0.87, 2.11; p < 0.00001), the rate of first hospitalization for heart failure or cardiovascular death (RR: 0.91; 95 % CI: 0.84, 0.98; p = 0.02). However, FCM did not show a significant impact on the risk of cardiovascular death (RR: 0.90; 95 % CI: 0.77, 1.05; p = 0.17), the need for intervention due to worsening heart failure (RR: 0.41; 95 % CI: 0.04, 4.51; p = 0.47), or all-cause mortality rates (RR: 0.89; 95 % CI: 0.69, 1.16; p = 0.28). Conclusion While FCM treatment in patients with heart failure and iron deficiency anemia significantly improves functional capacity and quality of life, it has no notable effect on mortality rates or the likelihood of hospitalization. These findings highlight the need for further research to explore comprehensive treatment strategies that address both the symptomatic and survival aspects of heart failure management in this patient population.
