This study aims to investigate the effect of amantadine use on neurological outcomes and mortality in patients with severe traumatic brain injury (TBI) (Glasgow coma score [GCS] between 3 and 8) who have been followed up on mechanical ventilators in the intensive care unit (ICU). Data from the hospital's electronic records were retrospectively searched. Patients over 18 years of age, with severe brain trauma (GCS between 3-8), who were treated with endotracheal intubation and invasive mechanical ventilation at admission to the ICU, and who were treated with Amantadine hydrochloride at least once in the first week of follow-up were included in the study.

Objective: The aim of this study was to investigate both the presence and severity of collapse in anatomical regions defined by the VOTE score (velum, orofarinx, tongue, and epiglottis), during drug induced sleep endoscopy (DISE) in patients diagnosed with obstructive sleep apnea, based on the bi-spectral index (BIS) sedation level.

Methods: In order to conduct a meta-analysis of articles examining the relationship between the VOTE score and BIS sedation level in determining the presence and severity of upper airway collapse during DISE, a literature review was performed.

Results: As a result of the search made in the specified databases, a total of 1864 articles were reached.

Background: Children who underwent hematopoietic stem cell transplant (HSCT) transplants are at high risk of developing central-line-associated bloodstream infections (CLABSIs). The present study aimed to identify possible risk factors for mortality by analyzing the clinical and laboratory characteristics of patients diagnosed with CLABSI in our pediatric hematopoietic stem cell transplant unit.

Methods: The initial CLABSI episodes of 102 children were analyzed.

Background/aim: This study aimed to investigate the effects of oxygen therapy using a high flow nasal cannula (HFNC) on patients diagnosed with COVID-19 Acute Respiratory Distress Syndrome (C-ARDS) by utilizing electrical impedance tomography (EIT)-based parameters.

Materials And Methods: Oxygen therapy was administered to the patients at two different flow rates and two different positions: T0-baseline measurements were taken in the supine position before any therapy was initiated. T1-HFNC was administered in the supine position with a flow rate of 30 L/min.

To conduct a bibliographic analysis of obstructive sleep apnea (OSA) which has reached epidemic proportions and is a frequent, unknown, and important cause of perioperative morbidity and mortality, by examining the internationally most cited articles. For OSA, the most cited articles in the field of anesthesiology and reanimation, appropriate access terms were compiled and combined, and related publications were searched using the Thompson Reuters Web of Science Citation Indexing search engine. A total of 79 journal publications were found on OSA and anesthesia, with an average of 14.

The optically pure binaphthyl-based phosphoramidite ligands and their perfluorinated analogs have been first used for the preparation of chiral palladium nanoparticles (PdNPs). These PdNPs have been extensively characterized by X-ray diffraction, X-ray photoelectron spectroscopy, transmission electron microscopy, P NMR, and thermogravimetric analysis techniques. The circular dichroism(CD) analysis of chiral PdNPs exhibited negative cotton effects.

Article Synopsis
  • Low serum magnesium levels are common in ICUs and may be linked to new-onset atrial fibrillation (NOAF), which is under-researched.
  • A study with 110 ICU patients found that those with NOAF had lower median magnesium levels and a higher rate of hypomagnesemia compared to a control group.
  • NOAF is associated with higher mortality in critically ill patients, with hypomagnesemia identified as an independent risk factor for developing NOAF and increased hospital mortality.

Background: BKV-HC is one of the most significant complications of HSCT. This retrospective study aimed to determine the frequency of BKV-HC in pediatric patients undergoing HSCT, detect the associated risk factors for the development of BKV-HC, and explore the effects of post-transplantation Cy use.

Methods: Three hundred twenty-seven patients (girls: 121, boys: 206) were analyzed according to sex, conditioning regimen, transplantation type, donor relatedness, stem cell source, the presence and grade of aGVHD, CMV co-existence, and Cy use.

Objectives: To assess and compare contrast sensitivity function in the previously amblyopic and non-amblyopic "normal" eyes of patients with microtropia and anisometropia who achieved 20/20 visual acuity after occlusion therapy.

Materials And Methods: Contrast sensitivity was tested monocularly on both eyes of 34 successfully treated microtropic and 15 anisometropic subjects (visual acuity 20/20 in both eyes). Contrast sensitivity function was evaluated by CSV-1000E and age-matched nomograms were used (spatial frequencies of 3, 6, 12, and 18 cycles per degree [cpd]) for comparison.
