Background: The elderly US population is growing quickly and staying active longer. However, there is limited information on sports-related injuries in older adults.

Hypotheses: (1) National estimate and incidence of sports-related orthopaedic injuries in the US elderly population have increased over the last 10 years, (2) types and causes of sports-related injuries in the elderly have changed, and (3) elderly sports-related injuries will increase more than the number of treating physicians by 2040.

Digital Representation of Patients as Medical Digital Twins: Data-Centric Viewpoint.

Precision medicine involves a paradigm shift toward personalized data-driven clinical decisions. The concept of a medical "digital twin" has recently become popular to designate digital representations of patients as a support for a wide range of data science applications. However, the concept is ambiguous when it comes to practical implementations.

Use of flavor capsule cigarettes and their preliminary impact on smoking cessation in Mexico: an exploratory study.

Background: No study has assessed the impact of flavor capsule cigarettes (FCCs) on smoking cessation. Thus, the purpose of this exploratory study was to assess (1) the sociodemographic and smoking-related characteristics associated with using FCCs, and (2) the preliminary impact of FCCs on smoking cessation.

Methods: This study is a secondary data analysis of a single-arm study with 100 individuals living in Mexico who smoked and received a smoking cessation mHealth intervention and pharmacotherapy support.

Niche-derived Semaphorin 4A safeguards functional identity of myeloid-biased hematopoietic stem cells.

Somatic stem cell pools comprise diverse, highly specialized subsets whose individual contribution is critical for the overall regenerative function. In the bone marrow, myeloid-biased hematopoietic stem cells (myHSCs) are indispensable for replenishment of myeloid cells and platelets during inflammatory response but, at the same time, become irreversibly damaged during inflammation and aging. Here we identify an extrinsic factor, semaphorin 4A (Sema4A), which non-cell-autonomously confers myHSC resilience to inflammatory stress.

The impact of climate change on vulnerable populations in pediatrics: opportunities for AI, digital health, and beyond-a scoping review and selected case studies.

Climate change critically impacts global pediatric health, presenting unique and escalating challenges due to children's inherent vulnerabilities and ongoing physiological development. This scoping review intricately intertwines the spheres of climate change, pediatric health, and Artificial Intelligence (AI), with a goal to elucidate the potential of AI and digital health in mitigating the adverse child health outcomes induced by environmental alterations, especially in Low- and Middle-Income Countries (LMICs). A notable gap is uncovered: literature directly correlating AI interventions with climate change-impacted pediatric health is scant, even though substantial research exists at the confluence of AI and health, and health and climate change respectively.

Shaping epithelial tissues by stem cell mechanics in development and cancer.

Adult stem cells balance self-renewal and differentiation to build, maintain and repair tissues. The role of signalling pathways and transcriptional networks in controlling stem cell function has been extensively studied, but there is increasing appreciation that mechanical forces also have a crucial regulatory role. Mechanical forces, signalling pathways and transcriptional networks must be coordinated across diverse length and timescales to maintain tissue homeostasis and function.

From relaxed beliefs under psychedelics (REBUS) to revised beliefs after psychedelics (REBAS).

The Relaxed Beliefs Under pSychedelics (REBUS) model proposes that serotonergic psychedelics decrease the precision weighting of neurobiologically-encoded beliefs. We conducted a preliminary examination of two psychological assumptions of REBUS: (a) psychedelics foster acute relaxation and post-acute revision of confidence in mental-health-relevant beliefs; which (b) facilitate positive therapeutic outcomes and are associated with the entropy of EEG signals. Healthy individuals (N = 11) were administered 1 mg and 25 mg psilocybin 4-weeks apart.

Perspectives of Hospital Medicine Providers on the Management of Oropharyngeal Dysphagia in Patients with Dementia.

Background: Oropharyngeal dysphagia (dysphagia) is a common (up to 86%) and devastating syndrome in hospitalized older adults with dementia.

Objective: To describe the perspectives of dysphagia management in hospitalized patients with dementia among hospital medicine providers (i.e.

Medical management pathways for Cushing's disease in pituitary tumors centers of excellence (PTCOEs).

Purpose: A recent update of consensus guidelines for the management of Cushing's disease (CD) included indications for medical therapy. However, there is limited evidence regarding their implementation in clinical practice. This study aimed to evaluate current medical therapy approaches by expert pituitary centers through an audit conducted to validate the criteria of Pituitary Tumors Centers of Excellence (PTCOEs) and provide an initial standard of medical care for CD.

Hallmark discoveries in the biology of non-Wilms tumour childhood kidney cancers.

Approximately 20% of paediatric and adolescent/young adult patients with renal tumours are diagnosed with non-Wilms tumour, a broad heterogeneous group of tumours that includes clear-cell sarcoma of the kidney, congenital mesoblastic nephroma, malignant rhabdoid tumour of the kidney, renal-cell carcinoma, renal medullary carcinoma and other rare histologies. The differential diagnosis of these tumours dates back many decades, when these pathologies were identified initially through clinicopathological observation of entities with outcomes that diverged from Wilms tumour, corroborated with immunohistochemistry and molecular cytogenetics and, subsequently, through next-generation sequencing. These advances enabled near-definitive recognition of different tumours and risk stratification of patients.

An evaporite sequence from ancient brine recorded in Bennu samples.

Evaporation or freezing of water-rich fluids with dilute concentrations of dissolved salts can produce brines, as observed in closed basins on Earth and detected by remote sensing on icy bodies in the outer Solar System. The mineralogical evolution of these brines is well understood in regard to terrestrial environments, but poorly constrained for extraterrestrial systems owing to a lack of direct sampling. Here we report the occurrence of salt minerals in samples of the asteroid (101955) Bennu returned by the OSIRIS-REx mission.

Genetic ancestry concordant RNA splicing in prostate cancer involves oncogenic genes and associates with recurrence.

Black men suffer disproportionately from prostate cancer (PCa) compared to men of other races and ethnicities. Comparing the molecular landscape of PCa among Black and White patients has the potential to identify targets for development of new precision medicine interventions. Herein, we conducted transcriptomic analysis of prostate tumors and paired tumor-adjacent normals from self-reported Black and White PCa patients and estimated patient genetic ancestry.

Three-dimensional diffractive acoustic tomography.

Acoustically probing biological tissues with light or sound, photoacoustic and ultrasound imaging can provide anatomical, functional, and/or molecular information at depths far beyond the optical diffusion limit. However, most photoacoustic and ultrasound imaging systems rely on linear-array transducers with elevational focusing and are limited to two-dimensional imaging with anisotropic resolutions. Here, we present three-dimensional diffractive acoustic tomography (3D-DAT), which uses an off-the-shelf linear-array transducer with single-slit acoustic diffraction.

Pancreatectomies with vein resection: Two large institutions' experience of East and West.

Background: The effectiveness and preferred reconstruction methods of pancreatectomy associated with vein resection (PAVR) for pancreatic cancer, especially for the extensive portal vein/superior mesenteric vein (PV/SMV) resections (more than 4 cm), are still subjects of debate. The aim of this study is to evaluate the safety and feasibility of PAVR by analyzing data from two large institutions from different regions.

Methods: From 2008 to 2018, we identified consecutive series of patients with pancreatic cancer who underwent PAVR at Karolinska University Hospital (KUH), Sweden, and Cancer Institute Hospital, Japanese Foundation of Cancer Research (JFCR), Japan.

Advancements in bispecific antibodies for multiple myeloma: What's new and what lies ahead.

Recent advancements in multiple myeloma (MM) treatment-including immunomodulatory drugs, proteasome inhibitors, monoclonal antibodies, and T cell-redirecting therapies like chimeric antigen receptor (CAR) T cells and bispecific antibodies (BsAbs)-have significantly improved patient outcomes. However, MM remains incurable, highlighting the need for novel therapeutic strategies. BsAbs, which simultaneously target a tumor-specific antigen and CD3 on T cells, have shown promising efficacy.

Downmodulation of potassium conductances induces epileptic seizures in cortical network models via multiple synergistic factors.

Voltage-gated potassium conductances [Formula: see text] play a critical role not only in normal neural function, but also in many neurological disorders and related therapeutic interventions. In particular, in an important animal model of epileptic seizures, 4-aminopyridine (4-AP) administration is thought to induce seizures by reducing [Formula: see text] in cortex and other brain areas. Interestingly, 4-AP has also been useful in the treatment of neurological disorders such as multiple sclerosis (MS) and spinal cord injury, where it is thought to improve action potential propagation in axonal fibers.

Histone bivalency in CNS development.

Neuronal maturation is guided by changes in the chromatin landscape that control developmental gene expression programs. Histone bivalency, the co-occurrence of activating and repressive histone modifications, has emerged as an epigenetic feature of developmentally regulated genes during neuronal maturation. Although initially associated with early embryonic development, recent studies have shown that histone bivalency also exists in differentiated and mature neurons.

Timing and Outcomes of PCI in Conjunction With TAVR With Balloon-Expandable Valves.

Background: The optimal timing for percutaneous coronary intervention (PCI) in patients undergoing transcatheter aortic valve replacement (TAVR) is debatable.

Objectives: The aim of this study was to compare outcomes based on the timing of PCI in stable coronary artery disease patients undergoing TAVR.

Methods: Leveraging the STS/ACC TVT Registry and Medicare Linkage, we analyzed patients with stable coronary artery disease undergoing PCI and TAVR between 2015 and 2023 using the SAPIEN 3 balloon-expandable valve platform.

Clinical, Psychosocial, and Ethical Consideration in Assisted Reproductive Technology in Lesbian, Gay, Bisexual, Transgender and Queer+ Populations.

When evaluating reproductive care for lesbian, gay, bisexual, transgender, and queer+ patients, there are multiple factors that must be addressed from a clinician, clinic, and social standpoint. Clinicians should be trained in culturally humble and trauma-informed care; clinics should have intake forms that identify sexual orientation, gender identity, and pronouns. The clinic environment should be inclusive, with all gender or single-stall bathrooms, and patient-facing educational materials that are representative of individuals with diverse partnerships, races, and ethnicities.
