Utilization of Anti-obesity Medications After Bariatric Surgery: Analysis of a Large National Database.

Purpose: A significant proportion of patients experience insufficient weight loss or weight regain after bariatric surgery. There is a paucity of literature describing anti-obesity medication (AOM) use following bariatric surgery. We sought to identify prevalence and trends of AOM use following bariatric surgery.

Is open-capsule proton pump inhibitor associated with faster healing time for marginal ulceration after Roux-en-Y gastric bypass?

Background: Marginal ulceration (MU) is a significant cause of morbidity after Roux-en-Y gastric bypass (RYGB). Proton pump inhibitors (PPIs) are the primary treatment. Prior limited data suggest that open-capsule PPIs (OC-PPIs) improve MU healing compared with intact-capsule PPIs (IC-PPIs), necessitating further validation.

Association of Bariatric Surgery with Risk of Incident Obesity-Associated Malignancies: a Multi-center Population-Based Study.

Introduction: Obesity has a known association with certain types of malignancy, and we aimed to determine whether bariatric surgery has a protective effect against de novo obesity-associated cancer development in adult patients.

Methods: We performed a multi-center retrospective cohort studying utilizing TriNetX national database. Patients were identified utilizing ICD-10-CM coding, and propensity score matching was performed.

Meta-Analysis Comparing Distal Radial Artery Approach Versus Traditional for Coronary Procedures.

Distal radial artery access (DRA) is recommended as the preferred approach over the traditional proximal radial artery access (TRA) for coronary procedures; however, there are limited randomized controlled trials (RCTs) that compared the 2. We conducted an updated meta-analysis of all RCTs from inception to July 26, 2021, that compared DRA versus TRA in patients who underwent coronary procedures. The statistical analysis was performed using a random effect model to calculate risk ratios (RRs) with 95% confidence intervals (CIs).

NAD Repletion Reverses Heart Failure With Preserved Ejection Fraction.

[Figure: see text].

Xbp1s-FoxO1 axis governs lipid accumulation and contractile performance in heart failure with preserved ejection fraction.

Heart failure with preserved ejection fraction (HFpEF) is now the dominant form of heart failure and one for which no efficacious therapies exist. Obesity and lipid mishandling greatly contribute to HFpEF. However, molecular mechanism(s) governing metabolic alterations and perturbations in lipid homeostasis in HFpEF are largely unknown.

Intravoxel incoherent motion (IVIM)-derived parameters in diffusion-weighted MRI: Associations with prognostic factors in invasive ductal carcinoma.

Purpose: To investigate relationships between intravoxel incoherent motion (IVIM) metrics of invasive ductal carcinoma of the breast and prognostic factors.

Materials And Methods: This retrospective study included a total of 82 masses from 72 patients who underwent 3T breast magnetic resonance imaging (MRI) and diffusion-weighted imaging. IVIM metrics of tissue diffusivity (D ), pseudodiffusivity (D ), and perfusion fraction (D ) were measured using histogram analysis for whole lesion volumes.

Dual function of a living polymerization initiator through the formation of a chain-end-protecting cluster: density functional theory calculation.

Sodium benzanilide (Na(+)BA(-)) initiators have opened a new route to living anionic polymerization of n-hexylisocyanate (HIC) with 100% yield and controlled molecular weight. The NaBA initiators not only provide initiation points for polymerization by attacking HIC monomers but also successfully prevent back-biting side reactions without any help from additives. Our hypothesis on this dual function of the NaBA initiators is that they self-assemble to form protection shields around the chain ends.

Association of polymorphisms modulating low-density lipoprotein cholesterol with susceptibility, severity, and progression of rheumatoid arthritis.

Objective: Dyslipidemia, a risk factor for cardiovascular diseases, is more prevalent in patients with rheumatoid arthritis (RA) than in the general population. We investigated whether single-nucleotide polymorphisms (SNP) modulating low-density lipoprotein (LDL) cholesterol affect susceptibility, severity, and progression of RA.

Methods: We enrolled 302 patients with RA and 1636 healthy controls, and investigated the SNP modulating LDL cholesterol.

A general approach to controlling the surface composition of poly(ethylene oxide)-based block copolymers for antifouling coatings.

To control the surface properties of a polystyrene-block-poly(ethylene oxide) diblock copolymer, perfluorinated chemical moieties were specifically incorporated into the block copolymer backbone. A polystyrene-block-poly[(ethylene oxide)-stat-(allyl glycidyl ether)] [PS-b-P(EO-stat-AGE)] statistical diblock terpolymer was synthesized with varying incorporations of allyl glycidyl ether (AGE) in the poly(ethylene oxide) block from 0 to 17 mol %. The pendant alkenes of the AGE repeat units were subsequently functionalized by thiol-ene chemistry with 1H,1H,2H,2H-perfluorooctanethiol, yielding fluorocarbon-functionalized AGE (fAGE) repeat units.

Combining living anionic polymerization with branching reactions in an iterative fashion to design branched polymers.

This paper reviews the precise synthesis of many-armed and multi-compositional star-branched polymers, exact graft (co)polymers, and structurally well-defined dendrimer-like star-branched polymers, which are synthetically difficult, by a commonly-featured iterative methodology combining living anionic polymerization with branched reactions to design branched polymers. The methodology basically involves only two synthetic steps; (a) preparation of a polymeric building block corresponding to each branched polymer and (b) connection of the resulting building unit to another unit. The synthetic steps were repeated in a stepwise fashion several times to successively synthesize a series of well-defined target branched polymers.
