Bariatric surgery association with risk of recurrent stroke hospitalization among older stroke survivors with obesity: A national inpatient sample study (2016-2019).

Background And Aims: The paucity of large-scale data exploring the effect of prior bariatric surgery on recurrent stroke outcomes in older individuals with obesity who survived a stroke led us to address the gap, with an emphasis on the risk of recurrent stroke and its trends.

Methods: Retrospective analysis of the National Inpatient Sample data from 2016 to 2019. Older individuals with obesity who survived a stroke (>65 years) and had a recurrent acute ischemic stroke (AIS) hospitalization, with or without prior bariatric surgery (PBS), were identified using ICD-10 codes.

Comparing physiological impacts of positive pressure ventilation versus self-breathing via a versatile cardiopulmonary model incorporating a novel alveoli opening mechanism.

Mathematical models can be used to generate high-fidelity simulations of the cardiopulmonary system. Such models, when applied to real patients, can provide valuable insights into underlying physiological processes that are hard for clinicians to observe directly. In this work, we propose a novel modelling strategy capable of generating scenario-specific cardiopulmonary simulations to replicate the vital physiological signals clinicians use to determine the state of a patient.

Knowledge infrastructure for integrated data management and analysis supporting new approach methods in predictive toxicology and risk assessment.

The EU-ToxRisk project (2016-2021) was a large European project working towards shifting toxicological testing away from animal tests, towards a toxicological assessment based on comprehensive mechanistic understanding of cause-consequence relationships of chemical adverse effects. More than 40 partners from scientific institutions, industry and regulators coordinated their work towards this goal in a six-year long programme. The breadth and variety of data and knowledge generated, presented a challenging data management landscape.

Off-iso Winston-Lutz test on seven linear accelerators.

Purpose: The aim of this study is to find optimal gantry, collimator, and couch angles for performing single isocenter, multiple target stereotactic radiosurgery (SIMT-SRS). Nineteen angle sets were tested across seven linear accelerators for radiation-isocenter coincidence and off-isocenter coincidence. The off-isocenter Winston-Lutz test was performed to evaluate the accuracy of isocenter alignment for each angle set, and optimal angle sets as well as maximum off-isocenter distance to target for each angle set was determined.

In vivo CRISPR base editing for treatment of Huntington's disease.

Huntington's disease (HD) is an inherited and ultimately fatal neurodegenerative disorder caused by an expanded polyglutamine-encoding CAG repeat within exon 1 of the huntingtin (HTT) gene, which produces a mutant protein that destroys striatal and cortical neurons. Importantly, a critical event in the pathogenesis of HD is the proteolytic cleavage of the mutant HTT protein by caspase-6, which generates fragments of the N-terminal domain of the protein that form highly toxic aggregates. Given the role that proteolysis of the mutant HTT protein plays in HD, strategies for preventing this process hold potential for treating the disorder.

Meta-analysis of renin angiotensin aldosterone modulators mitigating atrial fibrillation risk in hypertensive patients.

Introduction: Hypertension is associated with left ventricular hypertrophy/enlargement/fibrosis and atrial ectopic rhythm, leading to an increased risk of Atrial Fibrillation (AF). We aimed to stratify the effect of Angiotensin Converting Enzyme Inhibitors (ACEi) and Angiotensin Receptor Blockers (ARB) on the risk of AF.

Methods: PubMed, Scopus, and Google Scholar databases were screened, and cross-citation was conducted for studies reporting AF in hypertensive patients on ACEi and ARB.

Rare variants analyses suggest novel cleft genes in the African population.

Non-syndromic orofacial clefts (NSOFCs) are common birth defects with a complex etiology. While over 60 common risk loci have been identified, they explain only a small proportion of the heritability for NSOFCs. Rare variants have been implicated in the missing heritability.

Effect of scaling on serum high-sensitivity C-reactive protein levels and periodontal parameters in systemically healthy women of reproductive age group with gingivitis.

Objective: Varying levels of sex hormones across the menstrual cycle in young systemically healthy females may alter tissue responses to plaque, resulting in increased gingival inflammation. Also, higher severity and prevalence of gingivitis has been demonstrated in adult women than men, attributed to hormonal changes. Further, it has been reported that gingivitis raises the levels of systemic inflammatory markers such as C-reactive protein.

Early Exposure to Orthopaedic Surgery.

Introduction: Disparities in early orthopaedic experiences among medical students prompt a critical examination of factors influencing the availability and nature of these exposures. While the current body of literature underscores the significance of early surgical exposure and mentorship in medical education, a notable gap exists in investigating early orthopaedic exposure and its specific impact on students from diverse backgrounds.

Methods: A 16-item questionnaire, approved by our institutional review board, was administered to fourth-year medical students (MS4) and first-year orthopaedic residents (PGY-1) across U.

Accuracy of Parent-Reported Allergies and Medications in Pediatric Dentistry.

To measure the accuracy of parent-reported allergies and medication usage by comparing parental reports during dental con- sultations to medical reports from their child's primary care physician. A retrospective chart review was performed for 862 eligible patients 17 years and younger seen in the Department of Pediatric Dentistry at Franciscan Children's, Boston, Mass., USA, and who were required to obtain medical clearance prior to initiating dental treatment with sedation or general anesthesia.

A loss-of-function AGTR1 variant in a critically-ill infant with renal tubular dysgenesis: case presentation and literature review.

Background: Renal tubular dysgenesis (RTD) is a severe disorder with poor prognosis significantly impacting the proximal tubules of the kidney while maintaining an anatomically normal gross structure. The genetic origin of RTD, involving variants in the ACE, REN, AGT, and AGTR1 genes, affects various enzymes or receptors within the Renin angiotensin system (RAS). This condition manifests prenatally with oligohydramninos and postnatally with persistent anuria, severe refractory hypotension, and defects in skull ossification.

Enhanced biodegradation of phenanthrene and anthracene using a microalgal-bacterial consortium.

Polycyclic aromatic hydrocarbons (PAHs) are chemicals that are released into the environment during activities of the petroleum industry. The bioaccumulation, carcinogenic and mutagenic potential of PAHs necessitates the bioremediation of these contaminants. However, bioremediation of PAHs has a number of limitations including the inability of a single microbe to degrade all of the PAH fraction's environmental constituents.

Deciphering the Dilemma: Anticoagulation for Heart Failure With Preserved Ejection Fraction (HFpEF).

Impairment in ventricular relaxation and preserved left ventricular ejection fraction are the two main features of heart failure with preserved ejection fraction (HFpEF) a difficult clinical condition. Therapeutic choices for HFpEF patients are still scarce despite its rising frequency and negative effects on morbidity and mortality, necessitating creative methods to enhance results. The increased thromboembolic risk seen in these individuals raises questions about the relevance of anticoagulation in the therapy of HFpEF.

Thin-film nanocomposite membranes for efficient removal of emerging pharmaceutical organic contaminants from water.

Membranes are receiving significant attention to remove emerging organic micropollutants (OMPs) from wastewater and natural water sources. Herein, we report the facile preparation of a novel thin-film nanocomposite (TFN) membrane with high permeability and efficient removal of OMPs. ZnO nanoparticles were first synthesized using the co-precipitation method and functionalized with N1-(3-Trimethoxysilylpropyl)diethylenetriamine to make the surface rich with amine groups and then synthesized nanomaterials were covalently cross-linked into the active layer during the interfacial polymerization (IP) process.
