The aim of this study was to indicate necessity of establishing sensitive methods for early detection of hepatobiliary tract disorders after exposure of medical staff to anesthetic gases, as well as to follow-up working conditions in operating rooms. The examined group comprised the medical staff of the Surgical Department of the Institute of Surgery in Novi Sad. In the group of examinees levels of bilirubin in blood were increased; prevalent increase of the indirect bilirubin occurred too, while she increase of the direct bilirubin concentration was almost insignificant. Alanine aminotransferase concentration was slightly increased in the examined group, while aspartate aminotransferase reacted in much more expressed concentration increase. On the basis of gathered results it can be concluded that there are, for now, slight functional hepatic changes in the exposed workers, which may be the consequence of exposure to anesthetic gases.

HIF-1α and VEGF Immunophenotypes as Potential Biomarkers in the Prognosis and Evaluation of Treatment Efficacy of Atherosclerosis: A Systematic Review of the Literature.
Front Biosci (Landmark Ed)
January 2025
Department of Pathology, Faculty of Medicine, School of Health Sciences, University of Thessaly, 41500 Larissa, Greece.
Background: Hypoxia-inducible factor 1 alpha (HIF-1α) and its related vascular endothelial growth factor (VEGF) may play a significant role in atherosclerosis and their targeting is a strategic approach that may affect multiple pathways influencing disease progression. This study aimed to perform a systematic review to reveal current evidence on the role of HIF-1α and VEGF immunophenotypes with other prognostic markers as potential biomarkers of atherosclerosis prognosis and treatment efficacy.
Methods: We performed a systematic review of the current literature to explore the role of HIF-1α and VEGF protein expression along with the relation to the prognosis and therapeutic strategies of atherosclerosis.
A randomized, placebo-controlled, cross-over trial of ketamine in Rett syndrome.
J Neurodev Disord

Rett Syndrome Research Trust, Trumbull, CT, USA.
Background: Preclinical studies and anecdotal case reports support the potential therapeutic benefit of low-dose oral ketamine as a treatment of clinical symptoms in Rett syndrome (RTT); however, no controlled studies have been conducted in RTT to evaluate safety, tolerability and efficacy.
Design: This was a sequentially initiated, dose-escalating cohort, placebo-controlled, double blind, randomized sequence, cross-over study of oral ketamine in 6-12-year-old girls with RTT to evaluate short-term safety and tolerability and explore efficacy.
Methods: Participants were randomized to either five days treatment with oral ketamine or matched placebo, followed by a nine-day wash-out period and then crossed-over to the opposite treatment.
Dose-dependent association of hyperoxia and decreased favorable outcomes in mechanically ventilated patients with traumatic brain injury, a retrospective cohort study.
Eur J Trauma Emerg Surg

Department of Intensive Care Medicine, University Medical Center Hamburg-Eppendorf, Martinistraße 52, 20246, Hamburg, Germany.
Purpose: In patients with traumatic brain injury (TBI), adequate oxygenation is crucial to optimize survival and neurological outcome. However, supranormal oxygen partial pressure (PaO) only leads to minor increase in cerebral oxygen delivery but can cause numerous pathophysiological disturbances. Therefore, we aimed to study effects of hyperoxia on patient outcome and identify optimum PaO ranges.

Background: Long-term controlled mechanical ventilation (CMV) in intensive care unit (ICU) induces ventilatory-induced-diaphragm-dysfunction (VIDD). The transition from CMV to assisted mechanical ventilation is a challenge that requires clinicians to balance over-assistance and under-assistance. While the effects of over-assistance on the diaphragm are well known, we aimed to assess the impact of under-assistance on diaphragm function and structure in piglet model with pre-existing VIDD (after long-term CMV) or without VIDD (short-term CMV).

JAMA Netw Open
January 2025
San Francisco Department of Public Health, San Francisco, California.
Importance: The rise of high-potency opioids such as fentanyl makes buprenorphine initiation challenging due to the risks of precipitated withdrawal, prompting the exploration of strategies, such as low-dose initiation (LDI) of buprenorphine. However, no comparative studies on LDI outcomes exist.
Objective: To evaluate outpatient outcomes associated with 2 LDI protocols of buprenorphine among individuals with opioid use disorder (OUD) using fentanyl.
