Febrile neutropenia is a major complication in patients with acute leukemia or those undergoing hematopoietic stem cell transplantation (HSCT). Understanding patient characteristics and susceptibility patterns in febrile neutropenia is essential for appropriate antimicrobial therapy. First-line agents should have Pseudomonas aeruginosa coverage, but with the increase in multi-drug resistant organisms, ceftazidime-avibactam has emerged as a new therapeutic option.

Vehicular Ad-hoc Networks (VANETs) are growing into more desirable targets for malicious individuals due to the quick rise in the number of automated vehicles around the roadside. Secure data transfer is necessary for VANETs to preserve the integrity of the entire network. Federated learning (FL) is often suggested as a safe technique for exchanging data among VANETs, however, its capacity to protect private information is constrained.

Left atrial strain (LAS) was recently introduced as a parameter that reflects on left atrial function. Consequently, changes in LAS can inform the development of cardiovascular diseases, hence providing a window for non-invasive and cost-effective testing of these diseases and their complications at early stages of development, potentially offering a segway towards preventive interventions. LAS has yet to be implemented into standard practice.

Lymphocytic Esophagitis: A Histologic Pattern of Various Underlying Disorders.

J Clin Gastroenterol

October 2024

Department of Pathology, School of Medicine, Lebanese American University, Byblos, Lebanon.

Background: Lymphocytic esophagitis (LyE) is a rare condition that has been reported in several case studies, but its diagnostic criteria and clinical significance are inconsistent. There are no established clinical associations, except for Crohn's disease in children. Our study aimed to determine if patients with LyE have distinct demographic or clinical characteristics when compared with patients with increased intraepithelial lymphocytes (IEL) in their esophageal biopsy.

Objective: While the relationship between smoking and subarachnoid hemorrhage is well established, data regarding the probability of detecting unruptured intracranial aneurysms (UIAs) in smokers remain sparse. The aim of this systematic review and meta-analysis is to provide a comprehensive understanding of the relationship between smoking and the likelihood of identifying UIAs in healthy asymptomatic patients who underwent brain imaging for indications unrelated to UIAs.

Methods: A systematic review was conducted following the PRISMA guidelines.

Background: Although total hip and total knee arthroplasty are highly successful operations, the decision of whether and when to undergo surgery is highly subjective and discretionary, and specific guidelines regarding readiness for surgery remain elusive. The nature of these decisions underscores the importance of shared decision-making, which is founded on the concept that patients substantially contribute to determining their own readiness for surgery. The OPTION survey was developed as a conversation aid to facilitate shared decision-making in the context of total joint arthroplasty.

Cyanobacteria, also known as blue-green algae, are a diverse phylum of photosynthetic, Gram-negative bacteria and one of the largest microbial taxa. These organisms produce cyanotoxins, which are secondary metabolites that can have significant impacts on both human health and the environment. While toxins like Microcystins and Cylindrospermopsins are well-documented and have been extensively studied, other cyanotoxins, including those produced by and , remain underexplored.

Veratridine Induces Vasorelaxation in Mouse Cecocolic Mesenteric Arteries.

Toxins (Basel)

December 2024

Univ. Angers, INSERM, CNRS, MITOVASC, Equipe CarME, SFR ICAT, 49000 Angers, France.

The vegetal alkaloid toxin veratridine (VTD) is a selective voltage-gated Na (Na) channel activator, widely used as a pharmacological tool in vascular physiology. We have previously shown that Na channels, expressed in arteries, contribute to vascular tone in mouse mesenteric arteries (MAs). Here, we aimed to better characterize the mechanisms of action of VTD using mouse cecocolic arteries (CAs), a model of resistance artery.

This scoping review summarizes two emerging electrical impedance technologies: electrical impedance myography (EIM) and electrical impedance tomography (EIT). These methods involve injecting a current into tissue and recording the response at different frequencies to understand tissue properties. The review discusses basic methods and trends, particularly the use of electrodes: EIM uses electrodes for either injection or recording, while EIT uses them for both.

Individuals with metabolic syndrome have a high risk of developing cardiovascular disorders that is closely tied to visceral adipose tissue dysfunction, as well as an altered interaction between adipose tissue and the cardiovascular system. In metabolic syndrome, adipose tissue dysfunction is associated with increased hypertrophy, reduced vascularization, and hypoxia of adipocytes, leading to a pro-oxidative and pro-inflammatory environment. Among the pathways regulating adipose tissue homeostasis is the wingless-type mammary tumor virus integration site family (Wnt) signaling pathway, with both its canonical and non-canonical arms.

Access to specialist plastic surgery in rural vs. Urban areas of Africa.

BMC Surg

December 2024

Department of Research and Education, Oli Health Magazine Organization, Research and Education, Kigali, Rwanda.

Introduction: Plastic surgery is an essential yet underdeveloped field in many African nations, especially in rural areas. The demand for plastic surgery is increasing, but differences in access to respective services between rural and urban domiciles remain ever existent, despite the exponentiation of trauma, burns, and congenital disorders. According to this review, urban areas have access to better facilities and specialized surgeons, while rural areas frequently lack infrastructure, educated healthcare personnel, and medical resources.

Objectives: It is estimated that 20% of patients undergoing elective abdominal aortic aneurysm (AAA) repair suffer from cardiomyopathy. This study examines the impact of reduced ejection fraction (EF) on the outcomes of endovascular aneurysm repair (EVAR) and compares the different types of cardiomyopathies causing reduction of EF. Our hypothesis is that reduction in EF is associated with higher mortality after EVAR.

Purpose: Geriatric physical therapy (PT) has evolved since 2011, when the Essential Competencies (ECs) in the Care of Older Adults at the Completion of the Entry-level Physical Therapy Professional Program of Study were published. The purpose of the ECs was to ensure that all entry-level physical therapists were prepared to meet the unique needs of the growing older adult population. Changes in population demographics, medical and research advances, coupled with advancements in the profession of PT, necessitate a revision of the ECs.
