Public Health.

Background: Nearly 1 in 3 older adults are living with mild cognitive impairment (MCI) or subjective cognitive decline (SCD), which places them at increased risk of developing Alzheimer's disease or related dementias (ADRD). Behavioral interventions can improve cognitive function and reduce dementia risk factors, but most are in-person and time-intensive. We are conducting a randomized, controlled trial to assess the impact of 12- and 24-week online interventions on cognitive function and dementia risk.

Donor Type Does Not Impact Late Graft Failure Following Reduced Intensity Allogeneic Hematopoietic Cell Transplantation with Post-Transplant Cyclophosphamide Based Graft-Versus-Host Disease Prophylaxis.

Background: Post-transplant cyclophosphamide (PTCy) is a commonly used graft-vs-host disease (GVHD) prophylaxis, particularly in the setting of haploidentical (haplo) hematopoietic cell transplantation (HCT). The rate of graft failure has been reported to be as high as 12-20% in haplo-HCT recipients using PTCy. The objective of this study was to determine if donor type influenced the risk of late graft failure following RIC HCT using PTCy-based GVHD prophylaxis.

Causes, Diagnostic Testing, and Treatments Related to Clinical Deterioration Events Among High-Risk Ward Patients.

Importance: Timely intervention for clinically deteriorating ward patients requires that care teams accurately diagnose and treat their underlying medical conditions. However, the most common diagnoses leading to deterioration and the relevant therapies provided are poorly characterized.

Objectives: We aimed to determine the diagnoses responsible for clinical deterioration, the relevant diagnostic tests ordered, and the treatments administered among high-risk ward patients using manual chart review.

Predictors of Durable Remission After Successful Surgery for Cushing Disease: Results From the Multicenter RAPID Registry.

Background And Objective: Cushing disease (CD) affects mortality and quality of life along with limited long-term remission, underscoring the need to better identify recurrence risk. The identification of surgical or imaging predictors for CD remission after transsphenoidal surgery has yielded some inconsistent results and has been limited by single-center, single-surgeon, or meta-analyses studies. We sought to evaluate the multicenter Registry of Adenomas of the Pituitary and Related Disorders (RAPID) database of academic US pituitary centers to assess whether robust nonhormonal recurrence predictors could be elucidated.

Patient and physician attitudes towards salvage stereotactic radiosurgery or radiotherapy for brain metastases.

Background: The experience of patients with brain metastases treated with stereotactic radiosurgery (SRS) may shape attitudes towards salvage therapy. Furthermore, physician attitudes towards salvage therapy may differ based on specialty and experience. Our objective is to compare physician attitudes and patient experiences with SRS.

Aortic tissue stiffness and tensile strength are correlated with density changes following proteolytic treatment.

Introduction: Dissection or rupture of the aorta is accompanied by high mortality rates, and there is a pressing need for better prediction of these events for improved patient management and clinical outcomes. Biomechanically, these events represent a situation wherein the locally acting wall stress exceed the local tissue strength. Based on recent reports for polymers, we hypothesized that aortic tissue failure strength and stiffness are directly associated with tissue mass density.

Comparative analysis of upfront stereotactic radiosurgery and watchful waiting in the management of newly diagnosed vestibular schwannomas: a systematic review and meta-analysis.

Vestibular schwannomas (VS) are benign intracranial tumors posing significant management challenges. This study aims to compare the outcomes of stereotactic radiosurgery (SRS) and watchful waiting (WW) in the management of newly diagnosed VS, integrating findings from both retrospective and the pioneering V-REX prospective trial. Adhering to PRISMA guidelines, a systematic review was conducted using MEDLINE, Embase, and Cochrane databases.

Nicotinamide Mononucleotide Supplementation: Understanding Metabolic Variability and Clinical Implications.

Recent years have seen a surge in research focused on NAD+ decline and potential interventions, and despite significant progress, new discoveries continue to highlight the complexity of NAD+ biology. Nicotinamide mononucleotide (NMN), a well-established NAD+ precursor, has garnered considerable interest due to its capacity to elevate NAD+ levels and induce promising health benefits in preclinical models. Clinical trials investigating NMN supplementation have yielded variable outcomes while shedding light on the intricacies of NMN metabolism and revealing the critical roles played by gut microbiota and specific cellular uptake pathways.

Effect of Heat Acclimatization, Heat Acclimation, and Intermittent Heat Training on Maximal Oxygen Uptake.

Background: Maximal oxygen uptake (VO) is an important determinant of endurance performance. Heat acclimation/acclimatization (HA/HAz) elicits improvements in endurance performance. Upon heat exposure reduction, intermittent heat training (IHT) may alleviate HA/HAz adaptation decay; however, corresponding VO responses are unknown.

Livestream, group movement program for people living with cognitive impairment and care partners: A randomized clinical trial.

Introduction: There are few widely-available, evidence-based options to support quality of life (QOL) for people living with Alzheimer's disease and related dementias.

Methods: We performed a randomized, controlled trial with a Waitlist control group to determine whether an online, livestream, mind-body, group movement program (Moving Together, 1 hour, 2 days/week, 12 weeks) improves QOL in people with cognitive impairment (PWCI) or care partners (CPs) and explore mechanisms of action. The primary outcome for both participants was self-reported QOL.

Minnelide suppresses GVHD and enhances survival while maintaining GVT responses.

Allogeneic hematopoietic stem cell transplantation (aHSCT) can cure patients with otherwise fatal leukemias and lymphomas. However, the benefits of aHSCT are limited by graft-versus-host disease (GVHD). Minnelide, a water-soluble analog of triptolide, has demonstrated potent antiinflammatory and antitumor activity in several preclinical models and has proven both safe and efficacious in clinical trials for advanced gastrointestinal malignancies.

Pavement ant extract is a chemotaxis repellent for C. elegans.

Ant behavior relies on a collection of natural products, from following trail pheromones during foraging to warding off potential predators. How nervous systems sense these compounds to initiate a behavioral response remains unclear. Here, we used chemotaxis assays to investigate how ant compounds are detected by heterospecific nervous systems.
