The wild edible plants offer a valuable resource for food and human nutrition. The current study aimed to analyze the proximate composition and ethno-medicinal profiles of twenty selected wild edible plants from the Malakand District, Pakistan. The proximate composition (moisture, ash, crude protein, crude fat, and dietary fiber) was analyzed following Association of Official Agricultural Chemists (AOAC) protocols.

  • Stroke-associated Hospital Acquired Pneumonia (HAP) is a serious concern for stroke patients, and this study investigates using machine learning to predict its occurrence based on national registry data.
  • The research involved analyzing data from nearly 10,000 stroke patients and comparing the performance of various machine learning models, with the Artificial Neural Network (ANN) achieving the best results.
  • Key predictors for HAP were identified through SHAP analysis, indicating that factors like stroke severity and arrival method significantly affect the risk of developing HAP, highlighting the potential for improved patient care through predictive modeling.

Purpose: To assess whether corneal nerve analysis can identify and differentiate patients with multiple sclerosis (MS) from those with epilepsy.

Methods: Participants with MS (n = 83), participants with epilepsy (n = 50), and healthy controls (HCs) (n = 20) underwent corneal confocal microscopy (CCM) and quantification of automated corneal nerve fiber length (ACNFL), automated corneal nerve fractal dimension (ACNFrD), and ACNFrD/ACNFL ratio of the subbasal nerve plexus.

Results: ACNFL (MS: P < 0.

Objective: We examined the presentation to hospital, subtypes of ischaemic stroke for patients admitted to stroke services in Qatar and their 90-day prognosis based on the modified Rankin Scale (mRS) for those with diagnosed and undiagnosed diabetes, hypertension and dyslipidaemia.

Methods: We conducted a retrospective analysis of patients admitted with acute ischaemic stroke from January 2014 to April 2024. The mRS was dichotomised with favourable outcome (0-2) and unfavourable outcome (3-6).

  • The study assesses the use of machine learning models to predict one-year mortality after an ischemic stroke, highlighting the importance of accurate predictions for personalized treatment strategies.
  • Logistic regression proved to be the most effective model, achieving an accuracy of 83% and identifying key factors like stroke severity, age, and pre-stroke functional status that influence mortality risk.
  • The findings suggest that early prediction of mortality can improve stroke care, though further research is necessary to validate the model across various clinical environments.

Multiple prognostic scores have been developed to predict morbidity and mortality in patients with spontaneous intracerebral hemorrhage(sICH). Since the advent of machine learning(ML), different ML models have also been developed for sICH prognostication. There is however a need to verify the validity of these ML models in diverse patient populations.

Background: MicroRNAs (miRNAs) participate in diverse cellular changes following acute ischemic stroke (AIS). Circulating miRNAs, stabilized and delivered to target cells via extracellular vesicles (EVs), are potential biomarkers to facilitate diagnosis, prognosis, and therapeutic modulation. We aimed to identify distinctive expression patterns of circulating EV-miRNAs in AIS patients.

Evaluating stroke campaigns and associated behavioural changes is crucial to assess intervention effectiveness and inform future strategies. We aimed to evaluate patient's and bystanders' foreknowledge of stroke signs and symptoms and their response at stroke onset. We interviewed stroke patients using a validated questionnaire or their bystanders if the stroke patient had disabling stroke.

Acute ischemic stroke is the most common cause of neurologic dysfunction caused by focal brain ischemia and tissue injury. Diabetes is a major risk factor of stroke, exacerbating disease management and prognosis. Therefore, discovering new diagnostic markers and therapeutic targets is critical for stroke prevention and treatment.

Background: Stroke is a major cause of death and disability worldwide and presents a significant burden on healthcare systems. This retrospective study aims to analyze the characteristics and outcomes of stroke patients admitted to Hamad General Hospital (HGH) stroke service in Qatar from January 2014 to July 2022.

Methods: The medical records of 15,859 patients admitted during the study period were analyzed.

Objective: This study investigated the association between Coronavirus Disease 2019 mRNA vaccination and stroke in Qatar.

Methods: Between December 1, 2020, and April 11, 2023, a matched case-control study was conducted to investigate the association between 3036 acute stroke cases and 3036 controls drawn from the entire population of Qatar.

Results: The adjusted odds ratio (aOR) for vaccination among cases compared to controls was 0.

Article Synopsis
  • Olanzapine is an atypical antipsychotic medication effective for treating schizophrenia, but there are concerns about its potential cardiovascular risks, particularly cardiomyopathy.
  • Recent studies suggest this condition may arise from olanzapine-related metabolic disturbances like weight gain and insulin resistance, alongside receptor antagonism that causes cardiovascular stress.
  • The review emphasizes the importance of monitoring patients for heart failure symptoms, recommending early detection, withdrawal of olanzapine, and appropriate medical treatment to improve outcomes.*

This research aimed to enhance dermal delivery and optimize depigmentation therapy by designing mesoporous silica nanoparticles (MSNs) encapsulating azelaic acid (AZA) within a gel matrix. The MSNs were prepared using the sol-gel method. After subsequent processes, including acid extraction and drug loading, were then elucidated through PDI, size, zeta-potential, entrapment efficiency, nitrogen adsorption assay, FE-SEM, thermogravimetric analysis, differential scanning calorimetry, Fourier transform infrared spectroscopy, X-ray diffraction, and tyrosinase inhibition assay, were employed to assess the formulation.

Article Synopsis
  • - The study analyzes stroke prevalence and risk factors in Qatar from January 2014 to September 2020, revealing that a significant portion of patients were diagnosed with ischemic stroke and had common risk factors like hypertension and diabetes.
  • - Out of nearly 12,000 patients analyzed, most were young, predominantly Asian and Arab men, with a median age of 52 years; emergency treatment for stroke was commonly received within 4.5 hours but only a small percentage underwent advanced interventions like thrombolysis.
  • - The findings suggest that stroke in Qatar reflects unique demographic and health challenges, indicating a need for tailored prevention and management strategies to address the rising incidence of stroke in this diverse population.

The EU aims for carbon neutrality by 2050, focusing on offshore wind energy. Investments in North Sea wind farms, with optimal wind resources, play a crucial role. We employed a high-resolution regional climate model, which incorporates a wind farm parametrization, to investigate and address potential mitigating impacts of large wind farms on power generation and air-sea fluxes.

Background: Following transient ischemic attack (TIA) and minor stroke, the risk of recurrent stroke can be significantly reduced with short-duration dual antiplatelet therapy (DAPT). We wish to investigate whether 10 days of DAPT is as effective as 21 days' treatment.

Study Design: This is an open-label, randomized, parallel-group study comparing whether 10 days of DAPT treatment (ASA + clopidogrel) is non-inferior to 21 days of DAPT in patients with acute ischemic stroke (AIS) or high-risk TIA.
