Background: The aim of this study was to assess the effect of Vitamins C and E on mortality, intensive care unit (ICU) length of stay, and Glasgow Outcome Scale-Extended (GOS-E) score of traumatic brain injury (TBI) patients.
Methods: Using data from records of patients in a retrospective cohort study, we included 1321 TBI patients, 269 treated and 1052 untreated, aged over 18 years with information on exposure (i.e., Vitamins C and E) and confounders. Age, Glasgow Coma Scale, pupil status, Rotterdam classification, blood sugar, blood pressure, international normalized ratio, and comorbidity of patients were considered as the confounding factors. Endpoints were GOS-E on follow-up, mortality, and ICU length of stay. Propensity score matching was performed to adjust the confounders.
Results: Based on the average treatment effect estimates, the use of Vitamins C and E reduced the risk of mortality (risk difference [RD]: -0.07; 95% confidence interval [CI]: -0.14--0.003) and reduced the length of ICU stay (RD -1.77 95% CI:-3.71-0.16). Furthermore, our results showed that GOS-E was improved significantly (RD: 0.09, 95% CI : 0.03-0.16).
Conclusion: Our study suggests that using Vitamins C and E could decrease mortality and length of ICU stay and improve the GOS-E score and functions of the patients with severe TBI. As they are safe and inexpensive medications, they can be used in routine practice in ICUs to improve the outcomes of TBI patients.

A case report of gastric antral vascular ectasia treated by endoscopic band ligation combined with lauromacrogol injection.
Medicine (Baltimore)
January 2025
Department of Gastroenterology, The Affiliated People's Hospital of Ningbo University, Ningbo, China.
Rationale: Gastric antral vascular ectasia (GAVE) is a rare acquired lesion characterized by vascular dilation in the gastric antrum, frequently results in occult or overt gastrointestinal bleeding. Endoscopic intervention remains the cornerstone of therapy. Argon plasma coagulation was previously considered a first treatment option.

Objective: Inflammation contributes to morbidity following subarachnoid hemorrhage (SAH). The authors of this study evaluate how applying noninvasive transauricular vagus nerve stimulation (taVNS) can target this deleterious inflammatory response following SAH and reduce the rate of radiographic vasospasm.
Methods: In this prospective, triple-blinded, randomized controlled trial, 27 patients were randomized to taVNS or sham stimulation.
Impact of attaining an aggressive PK/PD target with continuous infusion beta-lactams on the clinical efficacy of targeted therapy of early post-transplant Gram-negative infections in critically ill OLT recipients. An interim analysis of a 3-year prospective, observational, study.
J Infect Dis

Department of Medical and Surgical Sciences, Alma Mater Studiorum, University of Bologna, Italy.
Background: To assess the impact of attaining aggressive beta-lactam pharmacokinetic/pharmacodynamic (PK/PD) targets on clinical efficacy in critical orthotopic liver transplant (OLT) recipients with documented early Gram-negative infections.
Methods: OLT recipients admitted to the post-transplant ICU between June 2021 and May 2024 having documented Gram-negative infections treated with targeted therapy continuous infusion (CI) beta-lactams, and undergoing therapeutic drug monitoring (TDM)-guided beta-lactam dosing adjustment in the first 72 hours were prospectively enrolled. Free steady-state concentrations (fCss) of beta-lactams (BL) and/or of beta-lactamase inhibitors (BLI) were calculated, and aggressive PK/PD target attainment was measured.
Mucosal leishmaniasis is associated with the Leishmania RNA virus and inappropriate cutaneous leishmaniasis treatment.
PLoS One
January 2025
Departamento de Salud Pública, Facultad de Medicina, Universidad Nacional de Colombia, Bogotá, Colombia.
Background: Mucosal leishmaniasis (ML) is a severe clinical form of leishmaniasis that is characterized by the destruction of the nasal and/or the oral mucosae and appears as a late complication in 5% to 10% of cutaneous leishmaniasis (CL) cases produced by species belonging to Leishmania (Viannia) subgenus. Some strains of Leishmania spp. carry an RNA virus known as Leishmania RNA virus (LRV) that may contribute to the appearance of ML.
