Article Synopsis
  • Red blood cells (RBCs) possess endothelial NO synthase (eNOS) and transport nitric oxide (NO), which is important for heart health, but the role of RBC eNOS in protecting the heart from damage is not well understood.
  • Researchers used specially modified mice to differentiate between the functions of eNOS in RBCs and endothelial cells, discovering that RBC eNOS is crucial for limiting damage after heart attacks (acute myocardial infarction or AMI).
  • While endothelial cell (EC) eNOS affects blood flow and heart function, RBC eNOS was found to specifically protect against heart tissue damage during AMI, suggesting it could be a viable target for new heart attack treatments.

Article Synopsis
  • Arginase 1 (Arg1) is an enzyme that converts l-arginine into l-ornithine and urea, and its role in endothelial cells (ECs) may limit l-arginine availability for nitric oxide (NO) production, leading to vascular issues.
  • A study was conducted using EC-specific gene-targeted knockout (KO) mice to examine how the absence of Arg1 affects eNOS, vascular tone, and endothelial function in normal conditions.
  • Results showed that EC Arg1 KO mice maintained normal levels of l-arginine and NO, displayed preserved vascular relaxation, but had increased vasoconstriction response, suggesting that while Arg1 affects NO in specific organs, it does not majorly

Health consequences that persist beyond the acute infection phase of COVID-19, termed post-COVID-19 condition (also commonly known as long COVID), vary widely and represent a growing global health challenge. Research on post-COVID-19 condition is expanding but, at present, no agreement exists on the health outcomes that should be measured in people living with the condition. To address this gap, we conducted an international consensus study, which included a comprehensive literature review and classification of outcomes for post-COVID-19 condition that informed a two-round online modified Delphi process followed by an online consensus meeting to finalise the core outcome set (COS).

Background: Treatment of cancer patients in certified cancer centers, that meet specific quality standards in term of structures and procedures of medical care, is a national treatment goal in Germany. However, convincing evidence that treatment in certified cancer centers is associated with better outcomes in patients with pancreatic cancer is still missing.

Methods: We used patient-specific information (demographic characteristics, diagnoses, treatments) from German statutory health insurance data covering the period 2009-2017 and hospital characteristics from the German Standardized Quality Reports.

Background: High-risk human papillomavirus (hrHPV) testing is utilized in primary cervical cancer screening, generally along with cytology, to triage abnormalities to colposcopy. Most screening-based hrHPV testing involves pooled detection of any hrHPV or of HPV16/18. Cervical neoplasia progression risks based on extended hrHPV genotyping-particularly non-16/18 hrHPV types-are not well characterized.

We are at an exciting moment in time with the advancement of many vaccines, including a shigella vaccine for the world. It is instructive to look at the long road that some vaccines have traveled to recognize the remarkable accomplishments of those who were pioneers, appreciate the evolution of scientific and applied technology, and inform the future history of a vaccine that would have great potential for global health. To achieve this valuable retrospective, a narrative historical literature review was undertaken utilizing PubMed and Embase databases with relevant search terms.

Osteoarthritis of the hip (hip OA) is a leading cause of pain and disability in elderly people. If non-surgical therapies become ineffective, patients may consider total hip arthroplasty (THA). The biggest challenge in recommending a THA is identifying patients for whom the benefits of this procedure outweigh the potential risks.

Despite documented benefits of diabetes technology in managing type 1 diabetes, inequities persist in the use of these devices. Provider bias may be a driver of inequities, but the evidence is limited. Therefore, we aimed to examine the role of race/ethnicity and insurance-mediated provider implicit bias in recommending diabetes technology.

Programming of implantable cardiac devices, especially dual-chamber pacemakers, can be challenging in daily clinical practice. Precise knowledge of programmable parameters is important; furthermore, one should also be familiar with the specific algorithms of each manufacturer. During programming, the patient's individual requirements should be taken into account, but out-of-the-box programming should be avoided.

Anxiety and depressive symptoms are common problems in adolescence that could be addressed by means of preventive interventions. Even though transdiagnostic cognitive behavior therapy (T-CBT) is potentially an ideal strategy to deal with anxiety and depression, it has rarely been used for preventive purposes. In addition, so far, no study has used internet-delivered T-CBT to prevent anxiety and depression in adolescents.

Importance: Psychiatric and cognitive phenotypes have been associated with a range of specific, rare copy number variants (CNVs). Moreover, IQ is strongly associated with CNV risk scores that model the predicted risk of CNVs across the genome. But the utility of CNV risk scores for psychiatric phenotypes has been sparsely examined.

Cancer testis antigen PRAME is over-expressed in a variety of malignant cells but is not or minimally expressed in normal non-germ line cells. Adoptive transfer of PRAME-specific T cells is thus under investigation in clinical trials as an innovative therapeutic option for acute myeloid leukemia (AML). However, their senescence-inducing activity has not been studied.
