Background: The aim of this study was to characterize the risk of a delayed intracranial hemorrhage (ICH) in trauma patients on direct-acting oral anticoagulants (DOACs).

Methods: Patients on DOACs admitted to two Level I Trauma Centers between 2014 and 2017 were reviewed. Only patients with a negative admission CT brain were included. The primary outcome was a delayed ICH.

Results: Overall, 249 patients were included. The median age was 81 years with 82% undergoing a repeat CT. Three patients developed a delayed ICH (1.2%). One developed an ICH after receiving tissue plasminogen activator for a cerebrovascular accident after two negative CTs. Excluding this patient, the incidence dropped to 0.8%. None required neurosurgical intervention.

Conclusion: For patients at risk for a TBI who are on DOACs, repeat cross-sectional imaging of the brain when the initial imaging is negative is not necessary. A period of clinical observation may be warranted.

Promotion of physical activity by health professionals can increase physical activity participation among patients, however, implementing physical activity promotion within hospital systems is lacking. The Promotion of Physical Activity by Health Professionals (PROMOTE-PA) study is a hybrid type I effectiveness-implementation cluster randomised controlled trial evaluating the effectiveness of support for physical activity promotion by health professionals on physical activity participation of patients. Health professionals delivering outpatient healthcare services within four local health districts and one specialty health network in New South Wales, Australia will be included.

Obstacles to Early Diagnosis of Gaucher Disease.

Ther Clin Risk Manag

January 2025

National Human Genome Research Institute, National Institutes of Health, Bethesda, MD, USA.

Gaucher disease (GD) is a rare lysosomal storage disorder resulting from a deficiency of the lysosomal enzyme glucocerebrosidase caused by biallelic variants in the gene. Patients may present with a wide spectrum of disease manifestations, including hepatosplenomegaly, thrombocytopenia, bone manifestations, and in the case of GD types 2 and 3, neurodegeneration, cognitive delay, and/or oculomotor abnormalities. While there is no treatment for neuronopathic GD, non-neuronopathic manifestations can be efficiently managed with enzyme replacement therapy or substrate reduction therapy.

Background Laparoscopic appendicectomy is a commonly used approach for the surgical management of acute appendicitis. If complications arise, a blood transfusion may be necessary for patients undergoing emergency appendicectomy. The need for routine group and save (G&S) sampling prior to emergency laparoscopic appendicectomy remains a subject of ongoing discussion.

Background: Malnutrition is linked to more postoperative problems, a longer recovery period, and a higher death rate; preoperative nutritional condition is a critical factor in surgical outcomes.

Objective: This study aimed to evaluate the impact of preoperative nutritional status on surgical outcomes in general surgery patients and explore its broader public health implications.

Methodology: A two-year observational research with 440 adult patients undergoing general surgery was carried out between January 2022 and December 2023.

MicroRNAs signatures as potential molecular markers in mild cognitive impairment: a meta-analysis.

Front Aging Neurosci

January 2025

Experimental and Computational Biochemistry, Department of Nutrition and Biochemistry, Faculty of Sciences, Pontificia Universidad Javeriana, Bogotá, Colombia.

Mild cognitive impairment (MCI) is characterized by a decline in cognitive functioning without significant interference in daily activities. Its high heterogeneity and elevated conversion rate to dementia pose challenges for accurate diagnosis and monitoring, highlighting the urgent need to identify methodologies focused on the early detection and intervention of MCI. Due to their biological characteristics, microRNAs (miRNAs) are potential candidates as non-invasive molecular markers for the identification and assessment of MCI progression.
