Operative Time Learning Curve for an Image-Free Robotic Arm Assisted Total Knee Arthroplasty: A Cumulative Sum Analysis.

Background: Robotic arm assisted total knee arthroplasty (RA-TKA) aims to improve accuracy in bone resection, implant positioning, and joint alignment compared to manual TKA (M-TKA). However, the learning curve of RA-TKA can disrupt operating room efficiency, increase complications, and raise costs. This study examines the operative time learning curve of RA-TKA using a single robotic system.

ETV2/ER71 regulates hematovascular lineage generation and vascularization through an H3K9 demethylase, KDM4A.

ETV2/ER71, an ETS (E-twenty six) transcription factor, is critical for hematopoiesis and vascular development. However, research about the molecular mechanisms behind ETV2-mediated gene transcription is limited. Herein, we demonstrate that ETV2 and KDM4A, an H3K9 demethylase, regulate hematopoietic and endothelial genes.

Customizable large-scale HPLC fraction collection using low-cost 3D printing.

High-performance liquid chromatography (HPLC) is an invaluable technique that has been used for many decades for the separation of various molecules. The reproducible collection of eluates from these systems has been significantly improved via its automation by fraction collection systems. Current commercially available fraction collectors are not easily customizable, incompatible with other platforms, and come with a large cost barrier making them inaccessible to many researchers.

Criticality is Associated with Future Psychotherapy Response in Patients with Post-Traumatic Stress Disorder-A Pilot Study.

Background: Trauma-focused psychotherapy is treatment of choice for post-traumatic stress disorder (PTSD). However, about half of patients do not respond. Recently, there is increased interest in brain criticality, which assesses the phase transition between order and disorder in brain activity.

Assessment of Long-Term Degradation of Adsorbents for Direct Air Capture by Ozonolysis.

Porous adsorbents are a promising class of materials for the direct air capture of CO (DAC). Practical implementation of adsorption-based DAC requires adsorbents that can be used for thousands of adsorption-desorption cycles without significant degradation. We examined the potential degradation of adsorbents by a mechanism that appears to have not been considered previously, namely, ozonolysis by trace levels of ozone from ambient air.

Real-World Outcomes in Patients with Advanced Penile Squamous Cell Carcinoma Receiving Immune Checkpoint Inhibitors: A Single Institution Experience.

Introduction: Advanced penile squamous cell carcinoma (pSCC) is a rare and aggressive malignancy with a poor prognosis and an unmet need for biomarkers. We performed a retrospective evaluation of real-world efficacy, safety outcomes, and baseline inflammatory biomarkers in patients with advanced pSCC treated with immune checkpoint inhibitors (ICIs).

Methods: We performed a retrospective review of patients with advanced pSCC who received ICIs from 2012 to 2023 at the Winship Cancer Institute of Emory University in Atlanta, GA.

Eliminating invisible deaths: the woeful state of global rabies data and its impact on progress towards 2030 sustainable development goals for neglected tropical diseases.

Like other neglected diseases, surveillance data for rabies is insufficient and incompatible with the need to accurately describe the burden of disease. Multiple modeling studies central to estimating global human rabies deaths have been conducted in the last two decades, with results ranging from 14,000 to 74,000 deaths annually. Yet, uncertainty in model parameters, inconsistency in modeling approaches, and discrepancies in data quality per country included in global burden studies have led to recent skepticism about the magnitude of rabies mortality.

Development of an agenda for research and action on climate change and health in the Caribbean.

This paper delineates the development of the Caribbean Research for Action Agenda which aims to empower Caribbean Small Island Developing States to reduce their vulnerabilities to the effects of climate change on health. The Caribbean Research for Action Agenda emerged from collaboration between nongovernmental organizations, academic institutions, and multilateral agencies that organized a conference on climate change and health in the Caribbean. This Agenda was formulated by prioritizing research areas, synthesizing evidence from conference presentations and scientific literature, and holding consultations with stakeholders and experts.

Chronic Health Conditions in the Workplace: Work Stressors and Supportive Supervision, Work Design, and Programs.

A large and growing number of workers are managing chronic physical and mental health conditions while working, necessitating attention from both researchers and leaders and practitioners in organizations. Much of the current discourse around research and practice in this area is focused on prevention of chronic disease and rehabilitation of disability to help workers return to work. Less commonly attended to are workplace factors that can support the quality of working life and the longevity of working life for workers with chronic health conditions.

A Real-World Prospective Multiple Sclerosis Pregnancy Registry in the United States: PREG-MS.

Background And Objectives: Multiple sclerosis (MS) affects more than 1 million people in the United States, including reproductive-age women. There has been a paucity of prospective, pregnancy registries based on MS disease rather than medication exposures. A prospective MS pregnancy registry (PREG-MS) was established in 2017 as a prospective, single-cohort, real-world MS pregnancy registry in New England States of the United States, with goals to evaluate (1) course of MS and disease-modifying therapies (DMT) use during conception attempts and in the peripartum period, (2) pregnancy outcomes in women with MS (WwMS), and (3) longer-term developmental outcomes in offspring of WwMS.

A study to identify individuals at risk to be affected by late-onset Pompe disease who had previously been given a non-specific or tentative diagnosis for their muscle weakness (Pompe PURSUE).

Background: Late-onset Pompe disease (LOPD) is an autosomal recessive lysosomal storage disorder that results in severe progressive proximal muscle weakness. Over time, reductions in muscle strength result in respiratory failure and a loss of ambulation. Delayed diagnosis of LOPD deprives patients of treatments that can enhance quality of life and potentially slow disease progression.

The association of perceived health status and presence of chronic conditions with physical activity in childhood cancer survivors.

Purpose: Childhood cancer survivors (CCS) are at risk for therapy-related late effects. Physical activity (PA) can minimize some late effects risk, but rates of PA are low in CCS. We aimed to determine how perception of survivor health status and presence of chronic conditions are associated with patient- or proxy-reported PA.

Decoding the functional impact of the cancer genome through protein-protein interactions.

Acquisition of genomic mutations enables cancer cells to gain fitness advantages under selective pressure and, ultimately, leads to oncogenic transformation. Interestingly, driver mutations, even within the same gene, can yield distinct phenotypes and clinical outcomes, necessitating a mutation-focused approach. Conversely, cellular functions are governed by molecular machines and signalling networks that are mostly controlled by protein-protein interactions (PPIs).

Among the 23 111 participants who registered and were shipped an ActiGraph GT3X+ accelerometer, 21 219 participants returned the device with a complete wear log (91.

Mg-dependent mechanism of environmental versatility in a multidrug efflux pump.

Tripartite resistance nodulation and cell division multidrug efflux pumps span the periplasm and are major drivers of multidrug resistance among gram-negative bacteria. Cations, such as Mg, become concentrated within the periplasm and, in contrast to the cytoplasm, its pH is sensitive to conditions outside the cell. Here, we reveal an interplay between Mg and pH in modulating the structural dynamics of the periplasmic adapter protein, AcrA, and its function within the prototypical AcrAB-TolC multidrug pump from Escherichia coli.

Spaceflight alters protein levels and gene expression associated with stress response and metabolic characteristics in human cardiac spheroids.

Cardiomyocytes derived from human induced pluripotent stem cells (hiPSC-CMs) possess tremendous advantage for cardiac regeneration. However, cell survival is challenging upon cell transplantation. Since microgravity can profoundly affect cellular properties, we investigated the effect of spaceflight on hiPSC-CMs.
