Background: To understand the clinical outcomes of selenium therapy in patients with sepsis syndrome, we conducted a meta-analysis of randomized controlled trials (RCT).
Methods: A total of 13 RCTs comparing selenium and placebo for patients with sepsis were reviewed systematically.
Results: However, we could not detect the association of selenium treatment with a decreased mortality at different time course (relative risk [RR] [95% confidence interval, CI]: 0.94 [0.82-1.06] at day 28; 0.73 [0.36-1.47] at day 90; 1.16 [0.78-1.71] at 6 months; respectively). Selenium supplementation did not show favorable efficacy in the incidence of renal failure, secondary infection or duration of mechanical ventilation (RR [95% CI]: 0.65 [0.41-1.03]; 0.96 [0.87-1.06]; standard mean difference [SMD] [95% CI]: 0.17 [-0.30-0.63]; respectively). Interestingly, we found that selenium therapy was benefit for sepsis patients with reduced duration of vasopressor therapy, staying time in intensive care unit and hospital, and incidence of ventilator-associated pneumonia (SMD [95% CI]: -0.75 [-1.37 to -0.13]; -0.15 [CI: -0.25 to -0.04]; -1.22 [-2.44 to -0.01]; RR [95% CI]: 0.61 [0.42-0.89]; respectively).
Conclusion: Based on our findings, intravenous selenium supplementation could not be suggested for routine use.

Women's, Children's and Adolescents' Health Program, Burnet Institute, Melbourne, Australia.
Background: Evidence suggests L-arginine may be effective at reducing pre-eclampsia and related outcomes. However, whether L-arginine can prevent or only treat pre-eclampsia, and thus the target population and timing of initiation, remains unknown.
Objectives: To evaluate the effects of L-arginine and L-citrulline (precursor of L-arginine) on the prevention and treatment of pre-eclampsia.

Segmental colectomy versus total proctocolectomy for ulcerative colitis: A systematic review and meta-analysis.
Colorectal Dis
January 2025
Cleveland Clinic, Cleveland, Ohio, USA.
Aim: Total proctocolectomy (TPC) is the standard of care for patients with ulcerative colitis (UC) and dysplasia not amenable to endoscopic management. However, the risks of an extensive resection may outweigh the benefits in high-risk surgical patients. Therefore, we performed a systematic review and meta-analysis to assess postoperative outcomes between segmental colectomy (SEG) versus TPC in patients with UC.

Background: This study investigated the impact of posaconazole (POSA) prophylaxis in COVID-19 patients with acute respiratory failure receiving systemic corticosteroids on the risk for the development of COVID-19-associated pulmonary aspergillosis (CAPA).
Methods: The primary aim of this prospective, multicentre, case-control study was to assess whether application of POSA prophylaxis in mechanically ventilated COVID-19 patients reduces the risk for CAPA development. All consecutive patients from centre 1 (cases) who received POSA prophylaxis as standard-of-care were matched to one subject from centre 2 and centre 3 who did not receive any antifungal prophylaxis, using propensity score matching for the following variables: (i) age, (ii) sex, (iii) treatment with tocilizumab and (iv) time at risk.
The Prevalence of Attention Deficit Hyperactivity Disorder in Psychotic Disorders: Systematic Review and Meta-analysis.
Schizophr Bull
January 2025
Orygen, Parkville, Victoria 3052, Australia.
Background: Although attention deficit hyperactivity disorder (ADHD) is known to be common in psychotic disorders, reported prevalence rates vary widely, with limited understanding of how different factors (eg, assessment methods, geographical region) may be associated with this variation. The aim was to conduct a systematic review and meta-analysis to determine the prevalence of ADHD in psychotic disorders and factors associated with the variability in reported rates.
Study Design: Searches were conducted in MEDLINE, Embase, PsycINFO, CINAHL, and Scopus in May 2023.
