Multiple sclerosis (MS) is an autoimmune disease of the central nervous system (CNS) with no definitive trigger. However, epidemiological studies indicate that environmental factors, such as infection with Epstein-Barr virus (EBV) and low vitamin D (Vit D) levels in genetically predisposed individuals, are important risk factors. One leading proposal is that EBV triggers MS via mechanisms such as molecular mimicry, where activated autoreactive B and T lymphocytes mistakenly target self-antigens.

Background: Perivascular Spaces (PVS) are a marker of cerebral small vessel disease (CSVD) that are visible on brain imaging. Larger PVS has been associated with poor quality of life and cognitive impairment post-stroke. However, the association between PVS and post-stroke sensorimotor outcomes has not been investigated.

Background: Pretreatment CT perfusion (CTP) marker relative cerebral blood volume (rCBV) < 42% lesion volume has recently shown to predict poor collateral status and poor 90-day functional outcome. However, there is a paucity of studies assessing its association with hemorrhagic transformation (HT). Here, we aim to assess the relationship between rCBV < 42% lesion volume with HT.

Background: Primary health care (PHC) services face operational challenges due to high patient volumes, leading to complex management needs. Patients access services through booked appointments and walk-in visits, with walk-in visits often facing longer waiting times. No-show appointments are significant contributors to inefficiency in PHC operations, which can lead to an estimated 3%-14% revenue loss, disrupt resource allocation, and negatively impact health care quality.

This study explores the integration of nanotechnology and Long Short-Term Memory (LSTM) machine learning algorithms to enhance the understanding and optimization of fuel spray dynamics in compression ignition (CI) engines with varying bowl geometries. The incorporation of nanotechnology, through the addition of nanoparticles to conventional fuels, improves fuel atomization, combustion efficiency, and emission control. Simultaneously, LSTM models are employed to analyze and predict the complex spray behavior under diverse operational and geometric conditions.

The microgrid (MG) faces significant security issues due to the two-way power and information flow. Integrating an Energy Management System (EMS) to balance energy supply and demand in Malaysian microgrids, this study designs a Fuzzy Logic Controller (FLC) that considers intermittent renewable sources and fluctuating demand patterns. FLC offers a flexible solution to energy scheduling effectively assessed by MATLAB/Simulink simulations.

Background And Aims: Guidelines suggest non-traumatic out-of-hospital cardiac arrest (OHCA) be conveyed to cardiac arrest centres (CAC). We hypothesised that (a) a pre-hospital conveyance algorithm based on initial presenting rhythm following OHCA is feasible and (b) that would demonstrate survival advantage.

Methods: This observational pilot study included all consecutive patients with OHCA from suspected cardiac aetiology from the county of Essex, United Kingdom from April 2022-April 2023.

Introduction: Transcatheter aortic valve replacement (TAVR) is increasingly in demand for treating severe aortic stenosis in a variety of surgical risk profiles. This means increasing wait times and elevated morbidity and mortality on the waitlist. To address this, we developed the SWIFT TAVR algorithm to prioritize patients based on clinical risk and reduce wait times.

Several challenges to validity have been identified with standard approaches used to measure "demand satisfied for modern methods of family planning." This study explored construct validity of the widely used indicator for "demand satisfied" by comparing the standard definition to alternative definitions of the indicator highlighting dimensions of women's own perceived demand, choice, and satisfaction. This cross-sectional study of women aged 15-49 years was conducted in Argentina (n = 1492), Ghana (n = 1600), and India (n = 1702) using a two-staged random sampling design.

Article Synopsis
  • The study focused on oral health prevention, particularly root caries measures, for patients aged 65 and older, and involved a survey of 365 Norwegian dental hygienists from both public and private sectors.
  • Key findings revealed that primary prevention methods included oral hygiene instruction and fluoride varnish, while challenges such as patients' reduced manual dexterity and mobility were particularly noted by public dental hygienists.
  • The research highlights the vital role of dental hygienists in promoting oral health for the elderly and underscores various challenges they face in implementing preventive care.

The effect of open-pit bauxite mining on beach sediment contamination in the urban coastal environment of Kuantan City, Malaysia, was investigated. The contents of 11 heavy metals (Pb, Cd, Al, Mn, Cu, Zn, Fe, As, Ni, Cr, and Ag) in 30 samples from Kuantan beach sediment zones (supratidal, intertidal, and subtidal) were determined using inductively coupled plasma optical emission spectrometry followed by contamination indexes, Pearson's correlation analysis, and principal component analysis (PCA). The results indicated that Cd, As, Ni, and Ag values in beach sediment zones were significantly higher compared to background values.

Purpose: Breast cancer (BC) brain metastasis (BrM) remains a significant clinical problem. Mucins have been implicated in metastasis; however, if they are also involved in BCBrM remains unknown. We queried BrM patient databases and found Mucin 5AC (MUC5AC) to be upregulated and therefore sought to define the role of MUC5AC in BCBrM.

Background: Early and accurate diagnosis of sepsis and the ensuing organ dysfunction remain a challenge in the postoperative setting. Susceptibility to infections, as well as the subsequent immunological response, are driven to some extent by the genetic predisposition of the patient. The purpose of this study was to identify novel genetic variants associated with postoperative sepsis (POS) and surgical site infections (SSIs).
