J Allergy Clin Immunol

December 2024

Department of Cardiology, Angiology and Intensive Care Medicine, University Hospital, Philipps University of Marburg, Marburg, Germany.

Long-COVID, an umbrella term referring to a variety of symptoms and clinical presentations, which emerge in a subset of patients after SARS-CoV-2 infection, has a significant impact on an individual's quality of life and places a substantial burden on healthcare systems worldwide, straining financial and human resources. The pathophysiology of long-COVID remains incompletely understood, though several hypotheses have been proposed to explain different aspects of this complex condition. SARS-CoV-2 persistence, direct organ damage, innate and adaptive immune system pertubation, autoimmunity, latent viruses reactivation, endothelial dysfunction, and microbiome disturbances are among the most relevant avenues for elucidating the evolution, complexity, and mechanisms of long-COVID.

Chronic kidney disease (CKD) and heart failure (HF) are interrelated conditions that exacerbate each other through mechanisms like fluid retention, neurohormonal activation, and inflammation. Red blood cell distribution width (RDW), a measure of red blood cell size variability, has emerged as a potential prognostic marker in HF. This study aimed to assess the prognostic value of RDW in HF patients, both with and without CKD, focusing on all-cause mortality and HF rehospitalizations.

Beyond the traditional distinctions of genome editing: evaluating a vulnerability framework.

Front Genome Ed

October 2024

Research Unit "Ethics of Genome Editing", Institute of Ethics and History of Medicine, University of Tübingen, Tübingen, Germany.

Article Synopsis
  • The 1982 Splicing Life report established key distinctions in genetic intervention: somatic vs. germline (heritable) and medical vs. non-medical (enhancement) applications, which have since shaped the ethical and legal frameworks in this field.
  • While somatic treatments are often favored, some controversies arise when they are used for enhancement, and the justification for germline interventions varies based on context (e.g., disease prevention vs. enhancement).
  • The paper argues for shifting the focus from whether technologies should be used to how they should be used, emphasizing the importance of addressing vulnerability and marginalization to guide effective global governance and policy development.

Despite the dramatic decrease in HIV-associated neurocognitive impairment (NCI) in the combined antiretroviral treatment (cART) era, subtler neuropsychological complications remain prevalent. In this review, we discuss the changing pathophysiology of HIV-associated NCI, considering recent evidence of HIV neuropathogenesis, and the pivotal role of cART. Furthermore, we address the multifactorial nature of NCI in people living with HIV, including legacy and ongoing insults to the brain, as well as host-specific factors.

Combination antiretroviral treatment (cART) has revolutionized the management of human immunodeficiency virus (HIV) and has markedly improved the disease burden and life expectancy of people living with HIV. HIV enters the central nervous system (CNS) early in the course of infection, establishes latency, and produces a pro-inflammatory milieu that may affect cognitive functions, even in the cART era. Whereas severe forms of neurocognitive impairment (NCI) such as HIV-associated dementia have declined over the last decades, milder forms have become more prevalent, are commonly multifactorial, and are associated with comorbidity burdens, mental health, cART neurotoxicity, and ageing.
