This article discusses the potential role of oral DHEA, available as a 'dietary supplement' in the US, in COVID-19 morbidity and mortality, calling for clinical trials to assess its safety.

In this study, dermoscopic examination of COVID-19 patients revealed significant microvascular changes in the proximal nailfold, such as avascular areas and disorganized capillary architecture, compared to healthy controls, with some regression of these changes observed over time.

In this study, immobilized VEGF selectively captured endothelial cells under various shear stresses, suggesting its potential for promoting endothelialization in vascular grafts or implanted tissues.

This review discusses the various skin lesions associated with COVID-19, which vary in type and severity, and reports that these lesions can appear before other symptoms and typically resolve spontaneously.

This study suggests that T-cell recruitment, thrombosis, and increased vascular permeability may contribute to various symptom clusters in post-acute sequelae of COVID-19 through shared cytokine elevation.

This case report describes a 23-year-old male patient with nail discoloration that may be associated with COVID-19, suggesting possible microvascular damage.

This review focuses on the various skin symptoms associated with COVID-19 but reports no new clinical findings.

This review explores the molecular mechanisms and potential roles of nitric oxide in COVID-19 therapy, but provides no new clinical results.

This study observed that in vitro exposure to dihydrotestosterone worsened COVID-19 spike protein-induced endothelial injury, while spironolactone showed potential in reducing this effect, suggesting a rationale for further evaluation in treating COVID-19.

This review discusses the emerging "endocrine phenotype" of COVID-19, highlighting the implications for managing diabetes, obesity, vitamin D deficiency, and other endocrine conditions in affected patients.

This review discusses biological sex differences in COVID-19 outcomes and reports no new clinical results; it identifies a need for studies to clarify how sex influences disease progression.

This review discusses targeting host cell proteases as a novel approach to inhibit SARS-CoV-2 infection, highlighting transcriptional modulation and enzymatic inhibition as promising therapeutic strategies, but it reports no new clinical findings.

This study explores how SARS-CoV-2 interacts with endocrine organs and highlights specific endocrine molecules that help explain the progression and outcomes of COVID-19, especially in patients with certain metabolic conditions.

Among adults suffering from post-COVID syndrome, this study reported fatigue as the most common long-term effect, observed in 71.4% of cases, followed by shortness of breath, anxiety/depression, and memory and attention deficits.

In this note, editors discuss the reproduction of medical content by Dr. Paul E. Marik, related to standardized coronavirus treatments, emphasizing that the materials appear effective and cautioning readers to consult their doctors for guidance.

This review discusses the development of the MATH+ treatment protocol for COVID-19 patients, detailing its scientific and clinical rationale, but reports no new experimental findings.

This review discusses the complex pathophysiological and clinical aspects of COVID-19, including dermatological findings and their association with SARS-CoV-2 infection but reports no new clinical results.

This review examines host factors like ACE2 and TMPRSS2 in SARS-CoV-2 infection, exploring how genetic variants and advanced cellular analyses might clarify COVID-19's severity and heterogeneity; it reports no new results.

This review highlights the potential of TCM medicinal foods for managing post-COVID disorders and suggests they could provide a safe and efficient long-term therapy due to their milder nature.

This review discusses the long-term complications of COVID-19, known as long COVID or PASC, and emphasizes the need to improve awareness and management strategies but reports no new clinical findings.

This review discusses factors contributing to COVID-19 severity disparities, highlighting age, comorbidities, race/ethnicity, and gender, and reports no new clinical findings; it emphasizes understanding these mechanisms to address risk differences.

This study reviews the complex pathophysiological mechanisms of long COVID and suggests a "treatable trait" approach for targeted interventions based on these mechanisms.

This review explores post-COVID-19 syndromes and the underlying mechanisms, including persistent inflammation, autoimmunity, and possible viral reservoirs, but reports no new clinical results.

Effective vaccines and treatments are crucial for long-term COVID-19 control.

This review discusses the role of sex hormones in COVID-19 severity and reports no new clinical results; the authors suggest further research for gender-based personalized treatment options.

This case report describes post-COVID-19 telogen effluvium in a 39-year-old patient, suggesting that COVID-19 may trigger significant hair loss as a late symptom.

This review explores recent advances in inflammation resolution and considers how macrophage reprogramming might help address severe COVID-19 outcomes, particularly those involving cytokine storms, but it reports no new experimental results.

This literature review found that Long COVID is a complex condition involving multiple body systems, influenced by factors like pre-existing conditions and vaccination status, with differing manifestations and persistence, complicating diagnosis and treatment efforts.

This narrative review outlines the diverse symptoms and possible mechanisms behind long COVID, such as immune dysregulation and viral persistence, while discussing ongoing and potential treatments, highlighting the current lack of proven effective therapies.

This review discusses the similarities between COVID-19 and acute radiation syndrome, highlighting their shared inflammatory responses and suggesting that insights from radiation biology could inform COVID-19 research and treatment approaches; it reports no new clinical results.
