Left ventricular assist device bioinformatics identify possible hubgenes and regulatory networks involved in the myocardium of patients with left ventricular assist device.

Objective: The aim of this study was to clarify the changes of myocardial gene expression profile after left ventricular assist device (LVAD) implantation and the related molecular biological significance.

Methods: A thorough bioinformatic analysis to evaluate the changes in gene expression profile in patients pre-LVAD and post-LVAD was conducted. Four relevant gene expression datasets-GSE430, GSE974, GSE21610, and GSE52601 from Gene Expression Omnibus (GEO) database were downloaded.

Comparative pathogenesis of two genotype VI.2 avian paramyxovirus type-1 viruses (APMV-1) in pheasants, partridges and chickens.

Newcastle disease (ND) is caused by virulent forms of -1 (APMV-1) and is an economically important disease of poultry world-wide. Pigeon paramyxovirus 1 (PPMV-1), a sub-group of APMV-1 is endemic in es and can cause infections of poultry. An outbreak of ND in partridges in Scotland, UK, in 2006 (APMV-1/partridge/UK(Scotland)/7575/06) was identified as a class II, genotype VI.

Trapeziectomy with Abductor Pollicis Longus Tendon Interposition Arthroplasty for First Carpometacarpal Joint Osteoarthritis: A Systematic Review.

Background: The prevalence of osteoarthritis (OA) of the first carpometacarpal (CMC) joint and subsequent thumb disability is rising. Abductor pollicis longus tendon interposition arthroplasty (APLTIA) has gained popularity as a procedure to alleviate pain and restore thumb function.

Methods: A systematic review was performed to assess the current reported outcomes of APLTIA.

Total arch replacement versus proximal aortic replacement in acute type A aortic dissection: Aggressive versus conservative.

Background: Acute type A aortic dissection (ATAAD) is a life-threatening medical condition requiring urgent surgical attention. It is estimated that 50% of ATAAD die within 24 h of onset, with the mortality rate is increasing by 1%-2% every additional hour without prompt intervention. A variety of ATAAD surgical repair techniques exist which has sparked controversy within the literature, with the main two strategies being proximal aortic replacement (PAR) and total arch replacement (TAR).

JMM Profile: Avian paramyxovirus type-1 and Newcastle disease: a highly infectious vaccine-preventable viral disease of poultry with low zoonotic potential.

Newcastle disease (ND) is a highly contagious disease of poultry caused by virulent avian paramyxovirus-1 (APMV-1) (previously termed avian avulavirus-1 and avian orthoavulavirus-1). APMV-1 is endemic in poultry in many developing countries, whilst outbreaks still occur in developed countries, affecting both commercial and backyard flocks. ND outbreaks can have substantial economic consequences due to high mortality rates and the imposition of trade restrictions.

A comparison of the lowest effective concentration in culture media for detection of chromosomal damage in vitro and in blood or plasma for detection of micronuclei in vivo.

It is often assumed that genotoxic substances will be detected more easily by using in vitro rather than in vivo genotoxicity tests since higher concentrations, more cytotoxicity and static exposures can be achieved. However, there is a paucity of data demonstrating whether genotoxic substances are detected at lower concentrations in cell culture in vitro than can be reached in the blood of animals treated in vivo. To investigate this issue, we compared the lowest concentration required for induction of chromosomal damage in vitro (lowest observed effective concentration, or LOEC) with the concentration of the test substance in blood at the lowest dose required for biologically relevant induction of micronuclei in vivo (lowest observed effective dose, or LOED).

Transcriptional profiles predict treatment outcome in patients with tuberculosis and diabetes at diagnosis and at two weeks after initiation of anti-tuberculosis treatment.

Background: Globally, the tuberculosis (TB) treatment success rate is approximately 85%, with treatment failure, relapse and death occurring in a significant proportion of pulmonary TB patients. Treatment success is lower among people with diabetes mellitus (DM). Predicting treatment outcome early after diagnosis, especially in TB-DM patients, would allow early treatment adaptation for individuals and may improve global TB control.

A concise history of echocardiography: timeline, pioneers, and landmark publications.

Echocardiography is less than 70 years old, and many major advances have occurred within living memory, but already some pioneering contributions may be overlooked. In order to consider what circumstances have been common to the most successful innovations, we have studied and here provide a timeline and summary of the most important developments in transthoracic and transoesophageal ultrasound imaging and Doppler techniques, as well as in intravascular ultrasound and imaging in paediatric cardiology. The entries are linked to a comprehensive list of first publications and to a collection of first-hand historical accounts published by early investigators.

Assessing innovative approaches for global health capacity building in fragile settings in the MENA region: development of the evaluation of capacity building (eCAP) program.

Background: Given the magnitude and frequency of conflicts in the MENA region along with their devastating impact on health responses and outcomes, there exists a strong need to invest in contextualized, innovative, and accessible capacity building approaches to enhance leadership and skills in global health. The MENA region suffers from limited (1) continued educational and career progression opportunities, (2) gender balance, and (3) skill-mix among its health workforce, which require significant attention.

Main Text: The Global Health Institute at the American University of Beirut incepted the Academy division to develop and implement various global health capacity building (GHCB) initiatives to address those challenges in fragile settings across low-and middle-income countries in the MENA region.

Impact of Patient Navigation on Population-Based Breast Screening: a Systematic Review and Meta-analysis of Randomized Clinical Trials.

Background: Unsatisfactory cancer screening results are often associated with poor prognosis. This study synthesized the literatures addressing the impact of patient navigation (PN) interventions on population-based breast cancer screening promotion to identify characteristics of the model for addressing breast cancer disparities.

Methods: We searched Pubmed, Embase, Web of Science, and the Cochrane Central Registry from inception to 31 December 2020 for randomized controlled trials (PROSPERO: CRD42021246890).

JMM Profile: Avian influenza: a veterinary pathogen with zoonotic potential.

Avian influenza viruses (AIVs) are classified as either low pathogenicity (LP; generally causing sub-clinical to mild infections) or high pathogenicity (HP; capable of causing significant mortality events in birds). To date, HPAIVs appear o be restricted to the haemagglutinin (HA) glycoprotein H5 and H7 AIV subtypes. Both LPAIV and HPAIV H5 and H7 AIV subtypes are classified as the causative agents of notifiable disease in poultry.

Evaluating an e-learning program to strengthen the capacity of humanitarian workers in the MENA region: the Humanitarian Leadership Diploma.

Background: The Middle East and North Africa (MENA) region is consistently plagued with humanitarian crises while having little response capacity. Despite their obvious growing need, there exist limited educational opportunities for humanitarian workers to develop their capacity in humanitarian topics. The present study evaluates an online training program, the Humanitarian Leadership Diploma (HLD), which targeted humanitarian workers across the MENA region.

Trends in Mortality From Novel Psychoactive Substances as "Legal Highs": Gender Differences in Manner of Death and Implications for Risk Differences for Women.

Introduction: This study aimed to examine drug-related deaths in the UK in which novel psychoactive substances (NPS) are an implicated substance, and to focus on female deaths in comparison with male deaths. While male overdoses dominate epidemiological statistics, there is an increase in female drug-related deaths and a narrowing of the gap between gender mortality rates which is to date unexplained.

Method: This study analyzed data from the National Programme for Substance Abuse Deaths (NPSAD) database that records drug-related deaths in the UK from coronial records.

Predicting outcomes of mesenteric ischemia postcardiac surgery: A systematic review.

Objective: This systematic review aims to identify predictors of outcomes of mesenteric ischemia in patients following cardiac surgery.

Methods: A comprehensive literature search was done on EMBASE, PubMed, Ovid MEDLINE, and SCOPUS using keywords relating to bowel ischemia and cardiac surgery. Database search results were screened by at least two authors and 32 articles were selected for inclusion in this review.

Global burden of heart failure: a comprehensive and updated review of epidemiology.

Heart Failure (HF) is a multi-faceted and life-threatening syndrome characterized by significant morbidity and mortality, poor functional capacity and quality of life, and high costs. HF affects more than 64 million people worldwide. Therefore, attempts to decrease its social and economic burden have become a major global public health priority.

Human Plasma Metabolomics Identify 9-cis-retinoic Acid and Dehydrophytosphingosine Levels as Novel biomarkers for Early Ventricular Fibrillation after ST-elevated Myocardial Infarction.

The relevant metabolite biomarkers for risk prediction of early onset of ventricular fibrillation (VF) after ST-segment elevation myocardial infarction (STEMI) remain unstudied. Here, we aimed to identify these imetabolites and the important metabolic pathways involved, and explore whether these metabolites could be used as predictors for the phenotype. Plasma samples were obtained retrospectively from a propensity-score matched cohort including 42 STEMI patients (21 consecutive VF and 21 non-VF).

Polycythaemia Vera and Coronary Artery Bypass Graft Surgery: A Systematic Review of the Literature.

Objectives: Polycythaemia vera (PV) is a condition that may potentially put patients undergoing cardiac surgery at an increased risk of bleeding and thrombosis; however, there is currently a paucity of literature regarding the management of these patients. We aim to examine the literature in this systematic review to indicate the interventions that may be considered to minimise complications.

Methods: We conducted a literature search using keywords and MeSH terms to identify articles discussing PV and cardiac surgery.

The Potential Therapeutic Role of Celastrol in Patients With Heart Failure With Preserved Ejection Fraction.

Analysis of left ventricular systolic dysfunction remained at the centre of heart failure research for many years (also known as heart failure with reduced ejection fraction, HFrEF). Although more than 50% of all heart failure patients experience a form of heart failure characterised by preserved ejection fraction (HFpEF), the pathophysiological mechanisms leading to this form of heart failure remain not well-understood. Several evidence-based treatments for HFrEF are in routine use, but there are limited evidence-based therapies for HFpEF.

Phenotyping heart failure patients for iron deficiency and use of intravenous iron therapy: data from the Swedish Heart Failure Registry.

Aims: Iron deficiency (ID) is associated with poor prognosis regardless of anaemia. Intravenous iron improves quality of life and outcomes in patients with ID and heart failure (HF) with reduced ejection fraction (HFrEF). In the Swedish HF registry, we assessed (i) frequency and predictors of ID testing; (ii) prevalence and outcomes of ID with/without anaemia; (iii) use of ferric carboxymaltose (FCM) and its predictors in patients with ID.
