Kaposi sarcoma-associated herpes virus (KSHV), also known as human herpes virus 8 (HHV-8), is the primary etiologic cause of Kaposi sarcoma (KS) and KSHV Inflammatory Cytokine Syndrome (KICS). Patients with KICS demonstrate symptoms of systemic inflammation, high KSHV viral load, elevation of inflammatory markers, and increased mortality. Management requires rapid diagnosis, treatment of underlying HIV, direct treatment of KS, and addressing the hyperimmune response.

Key populations are particularly vulnerable to human immunodeficiency virus (HIV) infection. Nearly half of Tajikistan's gross domestic product (GDP) originates from labor migrant transfers. While not officially designated as a key population, over 300,000 migrants return to Tajikistan every year at increased risk for HIV due to absence or interruption of treatment, change in risky behaviors, and other factors.

Snakes responsible for bites are rarely identified, resulting in a loss of information about snakebites from venomous species whose venom effects are poorly understood. A prospective clinical study including patients bitten by a snake was conducted in Cameroon between 2019 and 2021 to evaluate the efficacy and tolerability of a marketed polyvalent antivenom. Clinical presentation during the first 3 days of hospitalization was recorded following a standardized protocol.

National Centre for Epidemiology and Population Health, College of Health and Medicine, Australian National University, Canberra, ACT 2601, Australia.

Hepatitis B remains a major public health issue in Vietnam. Mandatory reporting to the national electronic communicable disease surveillance system (eCDS) has been required since July 2016. We conducted an evaluation of the hepatitis B surveillance system in Ninh Binh, the province with the highest reported burden of hepatitis B in Northern Vietnam, between 2017 and 2022.

Trachoma recrudescence is a serious concern for trachoma control programs. Programs define recrudescence as the return of trachomatous inflammation-follicular (TF) prevalence above elimination threshold (≥5%) on district-level trachoma surveillance surveys (TSSs). This study aimed to determine potential correlates of trachoma recrudescence within a historically highly endemic region.

Transitioning Adolescents to Adult HIV Care in the United States: Implementation Lessons from the Intervention Pilot Trial.

Trop Med Infect Dis

December 2024

Hubert Department of Global Health, Rollins School of Public Health, Emory University, 1518 Clifton Road, Atlanta, GA 30322, USA.

Although every youth in pediatric/adolescent HIV care will need to transition to adult-oriented care, there are no existing evidence-based interventions to optimize health through this process. Healthcare transition poses a persistent challenge to the health of youth living with HIV, which may result in gaps in care engagement, medication adherence, and viral suppression. Our process evaluation of , a multilevel mobile health (mHealth) intervention, included iterative interviews with youth, providers, and Transition Champions.

Community engagement has emerged as a critical component in the effective control and elimination of neglected tropical diseases (NTDs), particularly in regions with persistent stigma and limited healthcare access. Drawing on case studies from Brazil, India, and Nigeria, this opinion piece explores how community-driven initiatives have successfully improved leprosy awareness, reduced stigma, and fostered early case detection and treatment adherence. The importance of culturally sensitive, inclusive approaches in health education and stigma reduction campaigns is highlighted, emphasizing the potential for community engagement to enhance national leprosy programs and contribute to the World Health Organization's Zero Leprosy Strategy.

The COVID-19 pandemic has underscored the pivotal role of vaccines in mitigating the devastating impact of the virus. In Thailand, the vaccination campaign against SARS-CoV-2 began on 28 February 2021, initially prioritizing healthcare professionals before expanding into a nationwide effort on 7 June 2021. This study employs a mathematical model of COVID-19 transmission with vaccination to analyze the impact of Thailand's COVID-19 vaccination program from 1 March 2021 to 31 December 2022.

Leptospirosis is a widespread disease throughout the world, presenting in severe clinical forms in dogs. The pathogenicity of the different serovars in field infections is not fully documented, and clinical diagnosis is often limited to a combination of serological tests and molecular analyses. The latter, although a fundamental tool, cannot identify the infecting strain without further analysis.

Hemolytic-uremic syndrome (HUS) is a systemic complication of an infection with Shiga toxin (Stx)-producing enterohemorrhagic , primarily leading to acute kidney injury (AKI) and microangiopathic hemolytic anemia. Although free heme has been found to aggravate renal damage in hemolytic diseases, the relevance of the heme-degrading enzyme heme oxygenase-1 (HO-1, encoded by ) in HUS has not yet been investigated. We hypothesized that HO-1 also important in acute phase responses in damage and inflammation, contributes to renal pathogenesis in HUS.

Kojic acid is a secondary metabolite with strong chelating and antioxidant properties produced by and . Although antioxidants and chelators are important virulence factors for plant pathogens, the ecological role of kojic acid remains unclear. We previously observed a greater gene expression of antioxidants, especially kojic acid, by non-aflatoxigenic when co-cultured with aflatoxigenic Aflatoxin production was also reduced.

Background: The innate immune response aims to prevent pathogens from entering the organism and/or to facilitate pathogen clearance. Innate immune cells, such as macrophages, mast cells (MCs), natural killer cells and neutrophils, bear pattern recognition receptors and are thus able to recognize common molecular patterns, such as pathogen-associated molecular patterns (PAMPs), and damage-associated molecular patterns (DAMPs), the later occurring in the context of neuroinflammation. An inflammatory component in the pathology of otherwise "primary cerebrovascular and neurodegenerative" disease has recently been recognized and targeted as a means of therapeutic intervention.

(1) Background: Urinary tract infections (UTIs) are caused by the proliferation of pathogenic microorganisms, and they are the second most common hospital-acquired infections, with catheter-associated UTIs (CAUTIs) accounting for about 40% of these nosocomial infections. This review aims to identify the impact of technology on preventing infections in patients with urinary catheters; (2) Methods: The search was conducted in April 2024 through the EBSCOhost platform, with access to the American Search Complete, CINHAL Ultimate, Medline databases, and through the Scopus database; (3) Results: In total were included eight articles in this review. Technology interventions can significantly reduce the incidence of CAUTIs, decrease the duration of catheter use, improve diagnosis, and enhance patient safety; (4) Conclusions: Technological advancements show significant benefits in reducing infection rates and improving patient outcomes, like shorter hospital stays and comfort.

Carbonized Plant Powder Gel for Rapid Hemostasis and Sterilization in Regard to Irregular Wounds.

Nanomaterials (Basel)

December 2024

Collaborative Innovation Center for Nanomaterials & Devices, College of Physics, Qingdao University, Qingdao 266071, China.

Irregularly shaped wounds cause severe chronic infections, which have attracted worldwide attention due to their high prevalence and poor treatment outcomes. In this study, we designed a new composite functional dressing consisting of traditional Chinese herb carbonized plant powder (CPP) and a polyacrylic acid (PAA)/polyethylenimine (PEI) gel. The rapid gelation of the dressing within 6-8 s allowed the gel to be firmly attached to an irregularly shaped wound surface and avoided powder detachment.
