Multimodal Therapy May be Key to Improving Survival for Octogenarians Undergoing Pancreaticoduodenectomy for Pancreatic Ductal Adenocarcinoma: An American Multicenter Analysis.

Background: As the population ages, the number of octogenarians with pancreatic ductal adenocarcinoma (PDAC) continues to rise. Morbidity and mortality following pancreatectomy have improved owing to safer surgery and better chemoradiation regimens. This study compares the outcomes and multimodality utilization in octogenarians (≥80 years) who underwent pancreaticoduodenectomy (PD) for PDAC, with a younger cohort.

Egg donation advertisements: addressing the regulatory gap.

Egg donation is a procedure that is powerfully advertised as a beneficial experience with limited mention of the associated risks. Egg donor recruitment advertisements target young and financially insecure women and can serve as a catalyst for interest in egg donation. In the absence of explicit egg donation advertisement regulations and without counterbalancing information from other sources, potential donors may not be able to recognize how advertisements can be misleading.

Screening Young Adult Cancer Patients for Vocational Rehabilitation Services: A Vocational Rehabilitation Readiness Screening Tool.

Purpose: We aimed to develop an online vocational rehabilitation (VR) readiness screening (VRRS) tool for young adults diagnosed with cancer. VR readiness was defined as being physically and cognitively ready to enter or return to work or school.

Methods: We developed an initial VRRS tool informed by previous studies, a scoping review to determine such a tool had not already been developed, and consultation with subject matter experts.

Rethinking the residual approach: leveraging statistical learning to operationalize cognitive resilience in Alzheimer's disease.

Cognitive resilience (CR) describes the phenomenon of individuals evading cognitive decline despite prominent Alzheimer's disease neuropathology. Operationalization and measurement of this latent construct is non-trivial as it cannot be directly observed. The residual approach has been widely applied to estimate CR, where the degree of resilience is estimated through a linear model's residuals.

The Sub 2-h Official Marathon is Possible: Developing a Drafting Strategy for a Historic Breakthrough in Sports.

Background: Drafting for drag reduction is a tactic commonly employed by elite athletes of various sports. The strategy has been adopted by Kenyan runner Eliud Kipchoge on numerous marathon events in the past, including the 2018 and 2022 editions of the Berlin marathon (where Kipchoge set two official world records), as well as in two special attempts to break the 2 h mark for the distance, the Nike Breaking2 (2017) and the INEOS 1:59 Challenge (2019), where Kipchoge used an improved drafting formation to finish in 1:59:40, although that is not recognized as an official record.

Results: In this study, the drag of a realistic model of a male runner is calculated by computational fluid dynamics for a range of velocities.

Preclinical use of a clinically-relevant scAAV9/SUMF1 vector for the treatment of multiple sulfatase deficiency.

Background: Multiple Sulfatase Deficiency (MSD) is a rare inherited lysosomal storage disorder characterized by loss of function mutations in the SUMF1 gene that manifests as a severe pediatric neurological disease. There are no available targeted therapies for MSD.

Methods: We engineered a viral vector (AAV9/SUMF1) to deliver working copies of the SUMF1 gene and tested the vector in Sumf1 knock out mice that generally display a median lifespan of 10 days.

Machine learning meta-analysis identifies individual characteristics moderating cognitive intervention efficacy for anxiety and depression symptoms.

Cognitive training is a promising intervention for psychological distress; however, its effectiveness has yielded inconsistent outcomes across studies. This research is a pre-registered individual-level meta-analysis to identify factors contributing to cognitive training efficacy for anxiety and depression symptoms. Machine learning methods, alongside traditional statistical approaches, were employed to analyze 22 datasets with 1544 participants who underwent working memory training, attention bias modification, interpretation bias modification, or inhibitory control training.

Background/objective: To evaluate the weight and height status of under-five children between 1992 and 2021 in relation to nutritional context.

Subjects/methods: The study is based on the lengths/heights and weights of children <5 years in five national surveys (n = 505,026). After evaluating normality of the distributions, heights, and weights were expressed as z-scores relative to the WHO reference.

Social epidemiology of early adolescent nutrition.

Background: This study aimed to investigate associations between sociodemographic factors and dietary intake among a diverse population of early adolescents ages 10-13 years in the United States.

Methods: We examined data from the Adolescent Brain Cognitive Development (ABCD) Study in Year 2 (2018-2020, ages 10-13 years, N = 10,280). Multivariable linear regression models were conducted to estimate the adjusted associations between sociodemographic factors (age, sex, race and ethnicity, household income, parental education) and dietary intake of various food groups, measured by the Block Kids Food Screener.

International myeloma working group immunotherapy committee recommendation on sequencing immunotherapy for treatment of multiple myeloma.

T-cell redirecting therapy (TCRT), specifically chimeric antigen receptor T-cell therapy (CAR T-cells) and bispecific T-cell engagers (TCEs) represent a remarkable advance in the treatment of multiple myeloma (MM). There are several products available around the world and several more in development targeting primarily B-cell maturation antigen (BCMA) and G protein-coupled receptor class C group 5 member D (GRPC5D). The relatively rapid availability of multiple immunotherapies brings the necessity to understand how a certain agent may affect the safety and efficacy of a subsequent immunotherapy so MM physicians and patients can aim at optimal sequential use of these therapies.

NIRS-BIDS: Brain Imaging Data Structure Extended to Near-Infrared Spectroscopy.

Functional near-infrared spectroscopy (fNIRS) is an increasingly popular neuroimaging technique that measures cortical hemodynamic activity in a non-invasive and portable fashion. Although the fNIRS community has been successful in disseminating open-source processing tools and a standard file format (SNIRF), reproducible research and sharing of fNIRS data amongst researchers has been hindered by a lack of standards and clarity over how study data should be organized and stored. This problem is not new in neuroimaging, and it became evident years ago with the proliferation of publicly available neuroimaging datasets.

GPX modulation promotes regenerative axonal fusion and functional recovery after injury through PSR-1 condensation.

Axonal fusion represents an efficient way to recover function after nerve injury. However, how axonal fusion is induced and regulated remains largely unknown. We discover that ferroptosis signaling can promote axonal fusion and functional recovery in C.

Short-term evolutionary implications of an introgressed size-determining supergene in a vulnerable population.

The Thorny Skate (Amblyraja radiata) is a vulnerable species displaying a discrete size-polymorphism in the northwest Atlantic Ocean (NWA). We conducted whole genome sequencing of samples collected across its range. Genetic diversity was similar at all sampled sites, but we discovered a ~ 31 megabase bi-allelic supergene associated with the size polymorphism, with the larger size allele having introgressed in the last ~160,000 years B.

A Community Initiative to Increase Colorectal Cancer Knowledge, Awareness, and Intent to Screen in an Underserved Region.

Colorectal cancer (CRC) is a leading cause of cancer-related deaths in the United States despite the availability of effective preventive screening. This project was designed as a community awareness initiative to increase CRC awareness, knowledge, and intent to discuss and complete CRC screening. This quasi-experimental study had a QI focus and used a convenience sample in a public setting assessing CRC awareness, knowledge, and intent to discuss and complete screening after participating in an inflatable colon tour.

Optimized Scaffold-Free Human 3D Adipose Tissue Organoid Culture for Obesity and Disease Modeling.

Obesity and type 2 diabetes (T2D) are strongly linked to abnormal adipocyte metabolism and adipose tissue (AT) dysfunction. However, existing adipose tissue models have limitations, particularly in the stable culture of fat cells that maintain physiologically relevant phenotypes, hindering a deeper understanding of adipocyte biology and the molecular mechanisms behind differentiation. Current model systems fail to fully replicate in vivo metabolism, posing challenges in adipose research.

Milk-derived bioactive peptides in insulin resistance and type 2 diabetes.

Diabetes is a global health issue affecting over 6% of the world and 11 % of the US population. It is closely linked to insulin resistance, a pivotal factor in Type 2 diabetes development. This review explores a promising avenue for addressing insulin resistance through the lens of Milk-Derived Bioactive Peptides (MBAPs).

Fluid secretion and luminal pressure control lateral branching morphogenesis in the embryonic avian lung.

During lung development, the embryonic airway originates as a wishbone-shaped epithelial tube, which undergoes a series of branching events to build the bronchial tree. This process depends crucially on cell proliferation and is thought to involve distinct branching modes: lateral branching, wherein daughter branches emerge along the length of a parent branch, and bifurcations, wherein the tip of a parent branch splits to form two new daughter branches. The developing airway is fluid-filled, and previous studies have shown that altered luminal pressure can influence rates of branching morphogenesis.

CDC WONDER: Trends in diabetes mellitus mortality in the United States from 1968 to 2021.

This study analyzes U.S. diabetes mortality trends from 1968 to 2019 using CDC WONDER data.

Osseointegration for transfemoral amputees: Influence of femur length and implant sizing on bone-implant contact and alignment.

Introduction: Clinical data on osseointegration (OI) for limb replacement indicates a concerning increase in mechanical complications after five years post-implantation. Since adequate bone-implant contact and proper implant alignment are critical factors for successful osseointegration, it is essential to identify the factors influencing these outcomes. This study aimed to assess the effects of residual femur length and implant sizing on bone-implant contact and implant alignment.

Muscle contributions to propelling the body upward differ between skipping and running.

Skipping represents a training alternative to running due to its lower knee contact forces and higher whole-body metabolic cost. The increased metabolic cost of skipping is associated with a higher vertical center-of-mass (COM) displacement during the support and flight phases of the skipping hop compared to running. However, skipping has lower muscle force impulses than running.

Methods to Adjust for Confounding in Test-Negative Design COVID-19 Effectiveness Studies: Simulation Study.

Background: Real-world COVID-19 vaccine effectiveness (VE) studies are investigating exposures of increasing complexity accounting for time since vaccination. These studies require methods that adjust for the confounding that arises when morbidities and demographics are associated with vaccination and the risk of outcome events. Methods based on propensity scores (PS) are well-suited to this when the exposure is dichotomous, but present challenges when the exposure is multinomial.

Endovascular Thrombectomy for Extracranial Internal Carotid Artery Occlusions With Large Ischemic Strokes: Insights From the SELECT2 Trial.

Background And Objectives: Although previous trials have established the efficacy and safety of endovascular thrombectomy (EVT) in large ischemic core strokes, most of them excluded patients with extracranial internal carotid artery (e-ICA) occlusion. We aimed to compare outcomes in patients with e-ICA occlusion and large ischemic core infarcts treated with EVT vs medical management (MM).

Methods: This was a secondary analysis of the SELECT2 trial, a randomized controlled trial conducted at 31 international sites.
