The molecular underpinnings of high-grade endometrial carcinoma (HGEC) metastatic growth and survival are poorly understood. Here, we show that ascites-derived and primary tumor HGEC cell lines in 3D spheroid culture faithfully recapitulate key features of malignant peritoneal effusion and exhibit fundamentally distinct transcriptomic, proteomic, and metabolomic landscapes compared with conventional 2D monolayers. Using a genetic screening platform, we identify MAPK14 (which encodes the protein kinase p38α) as a specific requirement for HGEC in spheroid culture.

Fibroblasts are important components in the tumor microenvironment and can affect tumor progression and metastasis. However, the roles of genetic variants of the fibroblast-related genes (FRGs) in the prognosis of non-small-cell lung cancer (NSCLC) patients have not been reported. Therefore, we investigated the associations between 26,544 single nucleotide polymorphisms (SNPs) in 291 FRGs and survival of NSCLC patients from the Prostate, Lung, Colorectal, and Ovarian (PLCO) Cancer Screening Trial.

Background: Though widely used, resting heart rate (RHR), as measured by a wearable device, has not been previously evaluated in a large cohort against a variety of important baseline characteristics.

Objective: This study aimed to assess the validity of the RHR measured by a wearable device compared against the gold standard of ECG (electrocardiography), and assess the relationships between device-measured RHR and a broad range of clinical characteristics.

Methods: The Project Baseline Health Study (PHBS) captured detailed demographic, occupational, social, lifestyle, and clinical data to generate a deeply phenotyped cohort.

Modern tennis forehand grip style and ball contact points have evolved to enhance power and topspin. Different grip styles and ball contacts are recommended; however, little data are available to support one over another. Through a quantitative experimental study, we sought to determine which grip style and ball contact point produced the greatest forces at static contact.

Endocrine therapies targeting the estrogen receptor (ER/ESR1) are the cornerstone to treat ER-positive breast cancers patients, but resistance often limits their effectiveness. Notable progress has been made although the fragmented way data is reported has reduced their potential impact. Here, we introduce EstroGene2.

Background: Acute lower respiratory tract infections (ALRIs) remain the leading infectious cause of death among children < 5 years, with viruses contributing to a large proportion of cases. Little is known about the epidemiology and etiology of viral ALRI in rural Bangladesh.

Methods: We enrolled 3- to 23-month-old children with ALRIs attending a subdistrict hospital outpatient clinic in Sylhet district in Bangladesh.

Purpose: Primarily, to evaluate the repeatability and reproducibility of the new non-contact esthesiometer (NCE) in healthy subjects. Secondarily, the corneal sensitivity threshold measurements of the NCE were compared with those of the Cochet-Bonnet esthesiometer (CBE).

Design: Assessment reliability study.

Background: The Food and Drug Omnibus Report Act, signed into law in 2022, requires industry sponsors to include diversity action plans in clinical study protocols. Defining reliable methodology for measures and benchmarks is critical to ensuring adequate and consistent representation of historically underrepresented patient populations in clinical trials.

Methods: We provide an Advancing Inclusive Research (AIR) Calculator, summary tables, and data query bank to support target setting for the development of diversity action plans and to take steps toward defining enrollment standards.

Establishing Core elements for a Prehospital Emergency Care Systems Evaluation Tool (PECSET) for systems in early stages of development: A Delphi consensus.

Prehosp Emerg Care

December 2024

Department of Emergency Medicine, Duke University School of Medicine, USA, Prehospital & Emergency Research Centre, Health Services & Systems Research, Duke-NUS Medical School, Singapore, Singapore.

Objectives: International Prehospital Emergency Care (PEC) standards have been primarily developed by and for high resource settings. Most PEC systems in Asia, which are still in the early stages of development, struggle to achieve these standards. There is a need for an evaluation tool which can define achievable basic building blocks for PEC systems in low resource settings to improve quality of PEC.

Importance: Distress is common among patients with cancer, and evidence of disparities associated with distress has been mixed. Head and neck cancer (HNC) is one of the most emotionally distressing cancers and is also a highly disparate disease. However, it is unknown whether there are disparities associated with patient-reported distress in HNC.

Application of digital tools and artificial intelligence in the Myasthenia Gravis Core Examination.

Front Neurol

December 2024

Department of Neurology & Rehabilitation Medicine, School of Medicine & Health Sciences, George Washington University, Washington, DC, United States.

Background: Advances in video image analysis and artificial intelligence provide opportunities to transform how patients are evaluated. In this study, we assessed the ability to quantify Zoom video recordings of a standardized neurological examination- the Myasthenia Gravis Core Examination (MG-CE)-designed for telemedicine evaluations.

Methods: We used Zoom (Zoom Video Communications) videos of patients with myasthenia gravis (MG) who underwent the MG-CE.

Background: The occurrence of post-traumatic stress disorder (PTSD) following a traumatic event is associated with biological differences that can represent the susceptibility to PTSD, the impact of trauma, or the sequelae of PTSD itself. These effects include differences in DNA methylation (DNAm), an important form of epigenetic gene regulation, at multiple CpG loci across the genome. Moreover, these effects can be shared or specific to both central and peripheral tissues.

Acute aortic dissection is considered a contraindication to the use of intravenous thrombolysis in patients presenting with acute ischaemic stroke, but less has been described about previously repaired dissections. We present a case of a woman in her 50s presenting with acute left hemiparesis with a known history of aortic dissection within the thrombolysis window. After multidisciplinary discussion with cardiothoracic surgery and discussion with the patient, she was treated with intravenous thrombolysis without complication.

Intraocular pressure (IOP) elevation is the primary risk factor and currently the main treatable factor for progression of glaucomatous optic neuropathy. In addition to direct clinical and living animal in vivo studies, ex vivo perfusion of anterior segments and whole eyes is a key technique for studying conventional outflow function as it is responsible for IOP regulation. We present well-tested experimental details, protocols, considerations, advantages, and limitations of several ex vivo model systems for studying IOP regulation.
