Physician Reasons for or Against Treatment Intensification in Patients With Metastatic Prostate Cancer.

Importance: Clarifying the underutilization of treatment intensification (TI) for metastatic castration-sensitive prostate cancer (mCSPC) may improve implementation of evidence-based medicine and survival outcomes.

Objective: To investigate physicians' beliefs about TI in mCSPC to understand the gap between evidence-based guidelines and clinical practice.

Design, Setting, And Participants: This survey study analyzed data from the Adelphi Real World retrospective survey, which comprised physician surveys that were linked to medical record reviews of US adult patients treated for mCSPC between July 2018 and January 2022.

Computational Fluid Dynamic Optimization of Micropatterned Surfaces: Towards Biofunctionalization of Artificial Organs.

Modifying surface topography to prevent surface-induced thrombosis in cardiovascular implants allows endothelialization, which is the natural thrombo-resistance of blood-contacting surfaces, and is deemed to be the only long-term solution for hemocompatible materials. We adapted a simulation framework to predict platelet deposition on a modified surface and developed an optimization strategy to promote endothelial retention and limit platelet deposition. Under supraphysiological bulk shear stress, a maximum of 79% linear coverage was achieved.

Adults With Intellectual Disabilities and Incontinence: Assessment and Toileting Issues.

Background: Urinary and bowel incontinence are more common in adults with intellectual disability (ID), compared to the general population. Little is known about their incontinence experiences and toileting issues. The aim was to learn about their experiences and toileting issues.

Qualitative understanding of experiences of people with cystic fibrosis in a treatment discontinuation trial: The QUEST study.

Background: As people with cystic fibrosis (PWCF) live longer due to the breakthrough drug elexacaftor-tezacaftor-ivacaftor (ETI), they have questioned whether other CF therapies could be safely discontinued. SIMPLIFY was the first prospective, randomized trial to evaluate non-inferiority of discontinuing versus continuing two therapies. The QUEST (Qualitative Understanding of Experiences in the SIMPLIFY Trial) study was conducted to understand experiences of PWCF enrolled in SIMPLIFY, including why they joined, perceptions of randomization, decision-making around study withdrawal, and considerations for future discontinuation studies.

Urinary Tract Infections Amongst Adults With Intellectual Disabilities With Urinary Incontinence.

Background: Between 26% and 52% of adults with intellectual disability experience urinary incontinence (UI). Little is known about the implications of urinary tract infections (UTIs) for this group. The aim was to screen for UTIs in a sample of adults with intellectual disability and UI.

The intestinal microbiome, but not clinical aspects of inflammatory bowel disease, is impacted by lactose malabsorption compared to lactose digestion in children.

Background: Dietary exclusion of lactose from patients with inflammatory bowel disease (IBD) persists with speculation that deleterious effects are mediated through intestinal microbes.

Objectives: To compare IBD characteristics and changes in the intestinal microbiome (IM) at diagnosis in children with and without lactose malabsorption (LM).

Methods: A cross-sectional cohort of children (8-17 y of age) diagnosed with Crohn's disease [n = 149 (63%)] or ulcerative colitis (n = 86) that had undergone lactose breath hydrogen testing was evaluated.

A Skeletal Muscle-Mediated Anticontractile Response on Vascular Tone: Unraveling the Lactate-AMPK-NOS1 Pathway in Femoral Arteries.

The regulation of vascular tone by perivascular tissues is a complex interplay of various paracrine factors. Here, we investigate the anti-contractile effect of skeletal muscle surrounding the femoral and carotid arteries and its underlying mechanisms. Using male and female Wistar rats, we demonstrated that serotonin, phenylephrine, and U-46619 induced a concentration-dependent vasoconstrictor response in femoral artery rings.

The Role of Matrix Stiffness And Viscosity on Lipid Phenotype And Fat Lineage Potential.

Autologous fat transfer is a common procedure that patients undergo to rejuvenate large soft tissue defects. However, these surgeries are complicated by limited tissue sources, donor-site morbidity, and necrosis. While the biofabrication of fat tissue can serve as a clinical option for reconstructive surgery, the influence of matrix mechanics, specifically stiffness and viscosity, on adipogenesis requires further elucidation.

Real-world evaluation of health-related quality of life in patients with diffuse large B-cell lymphoma based on a multinational survey.

Background: Real-world health-related quality of life (HRQoL) data in patients with diffuse large B-cell lymphoma (DLBCL) are scarce. This study is to compare patient-reported outcomes in patients with DLBCL across therapy lines and countries.

Methods: Data were derived from the Adelphi DLBCL Disease Specific Programme™ from January 2021 to May 2021, a survey of physicians and their DLBCL patients in France, Germany, Italy, Spain, United Kingdom (UK), and the United States (US).

Reversible Contraception in Males: An Obtainable Target?

The last few decades have brought contraception to the forefront of research, with great strides made in effectively targeting and optimizing the physiology, pharmacology, and delivery processes that prevent pregnancy. However, these advances still predominantly target female contraceptives for the prevention of contraception, whereas targeting the male sex has lagged far behind. This has led to a marked deficiency in safe and effective male contraceptive agents, resulting in a heavy dependence on female contraceptives to prevent unwanted and unplanned pregnancies.

Glycomacropeptide as an Efficient Agent to Fight Pathophysiological Mechanisms of Metabolic Syndrome.

There is currently a growing interest in the use of nutraceuticals as a means of preventing the development of complex diseases. Given the considerable health potential of milk-derived peptides, the aim of this study was to investigate the protective effects of glycomacropeptide (GMP) on metabolic syndrome. Particular emphasis was placed on the potential mechanisms mitigating cardiometabolic disorders in high-fat, high-fructose diet-fed mice in the presence of GMP or Bipro, an isocaloric control.

Biomechanical Remodeling of Aortic Valve Interstitial Cells During Calcified Lesion Formation In Vitro.

Healthy aortic heart valves are essential to the regulation of unidirectional blood flow. Calcific aortic valve disease (CAVD) is an actively progressive disease that involves the disorganization of valve cells and accumulation of calcium deposits on the aortic valve leaflets. CAVD involves disruption of cell environment homeostasis that prior cell culture models have found difficult to portray and model.

Spatial analysis of future climate risk to stormwater infrastructure.

Climate change is expected to result in more intense precipitation events that will affect the performance and design requirements of stormwater infrastructure. Such changes will vary spatially, and climate models provide a range of estimates of the effects on events of different intensities and recurrence. Infrastructure performance should be evaluated against the expected range of events, not just rare extremes.

NADPH oxidase 1 promotes hepatic steatosis in obese mice and is abrogated by augmented skeletal muscle mass.

Exercise as a lifestyle modification is a frontline therapy for nonalcoholic fatty liver disease (NAFLD), but how components of exercise attenuate steatosis is unclear. To uncouple the effect of increased muscle mass from weight loss in obesity, myostatin knockout mice were bred on a lean and obese background. Myostatin deletion increases gastrocnemius (Gastrocn.

The microbiome of two strategies for ammonia removal with the sequencing batch moving bed biofilm reactor treating cheese production wastewater.

Cheese production facilities must abide by sewage discharge bylaws that prevent overloading municipal water resource recovery facilities, eutrophication, and toxicity to aquatic life. Compact treatment systems can permit on-site treatment of cheese production wastewater; however, competition between heterotrophs and nitrifiers impedes the implementation of the sequencing batch moving bed biofilm reactor (SB-MBBR) for nitrification from high-carbon wastewaters. This study demonstrates that a single SB-MBBR is not feasible for nitrification when operated with anerobic and aerobic cycling for carbon and phosphorous removal from cheese production wastewater, as nitrification does not occur in a single reactor.

Interventions for preventing or controlling health care-associated infection among health care workers or patients within primary care facilities: A scoping review.

Background: This review aimed to synthesize the evidence on infection prevention and control interventions for the prevention of health care-associated infection among health care workers or patients within primary care facilities.

Methods: PubMed, CINAHL, EMBASE, and CENTRAL databases were searched for quantitative studies published between 2011 and 2022. Study selection, data extraction, and quality assessment using Cochrane and Joanna Briggs tools, were conducted by independent review with additional sensitivity checking performed on study selection.

Age-associated changes in the gut microbiome impact efficacy of tumor immunomodulatory treatments.

In-situ vaccination (ISV) utilizing nanoparticles (NPs) and therapeutic devices like focused ultrasound (FUS) can trigger immune-mediated killing of both treated and untreated cancer cells. However, the impact of confounding factors such as aging and gut microbiota composition on therapeutic outcomes remains poorly understood. In this study, we sequentially treated young mice (∼8 weeks) and old mice (>18 months) with bilateral melanoma using FUS and calreticulin nanoparticles (CRT-NP) to enhance immunogenic cell death.

Quantitative 4D imaging of biomechanical regulation of ventricular growth and maturation.

Abnormal cardiac development is intimately associated with congenital heart disease. During development, a sponge-like network of muscle fibers in the endocardium, known as trabeculation, becomes compacted. Biomechanical forces regulate myocardial differentiation and proliferation to form trabeculation, while the molecular mechanism is still enigmatic.

Changes in macrophage immunometabolism as a marker of skeletal muscle dysfunction across the lifespan.

One of the most pronounced changes in the elderly is loss of strength and mobility due to the decline of skeletal muscle function, resulting in a multifactorial condition termed sarcopenia. Although significant clinical changes begin to manifest at advanced ages, recent studies have shown that changes at the cellular and molecular level precede the symptomatology of sarcopenia. By utilizing a single-cell transcriptomic atlas of mouse skeletal muscle across the lifespan, we identified a clear sign of immune senescence that presents during middle age.
