Background: Human herpesvirus 8 (HHV-8) is associated with Kaposi's sarcoma. In the US and Europe, HHV-8 is believed to be mainly sexually transmitted, but reports from some African countries suggest non-sexual transmission.
Objectives: To find out more about HHV-8 seroprevalence and transmission in Eastern Africa.
Study Design: In this study, 411 serum samples from different population groups in Eritrea (children, pregnant women, female sex workers and members of the isolated Rashaida tribe) were examined for HHV-8 antibodies with an immunofluorescence assay detecting antibodies to latent and lytic HHV-8 antigens.
Results: Antibodies to HHV-8 latent antigen were found in 0-2% of Eritrean children, 5% of pregnant women, 8% of female sex workers and 26% of Rashaidas, respectively. No correlation was found between detectable HHV-8 antibodies and seropositivity to HIV or herpes simplex 2.
Conclusions: These results suggest that HHV-8 infection is relatively common in Eritrea and that viral transmission occurs predominantly through non-sexual route in this region.

Demographic and clinical trends of young breast cancer patients from the national cancer database: disproportionate effect on minority populations.
Breast Cancer Res Treat
January 2025
Division of Medical Oncology, Department of Medicine, Samuel Oschin Comprehensive Cancer Institute, 8700 Beverly Blvd., Los Angeles, CA, 90048, USA.
Purpose: There is an increasing incidence of young breast cancer (YBC) patients with uncertainty surrounding the factors and patterns that are contributing.
Methods: We obtained characteristics and survival data from 206,156 YBC patients (≤ 40 years of age) diagnosed between 2005 and 2019 from the National Cancer Database (NCDB). Patients were subdivided into two comparison groups based on year of diagnosis (2005-2009, Old vs.
Exploring the Relationship Between Combined, Acetabular, and Femoral Version on Postoperative Outcomes 2 Years After Hip Arthroscopy for Femoroacetabular Impingement Syndrome.
Am J Sports Med
January 2025
Section of Young Adult Hip Surgery, Division of Sports Medicine, Department of Orthopedic Surgery, Rush University Medical Center, Chicago, Illinois, USA.
Background: Many studies have examined the prevalence of acetabular version (AV) and femoral version (FV) abnormalities and their effect on patient-reported outcomes (PROs) after hip arthroscopy for femoroacetabular impingement syndrome (FAIS), but few have explored the prevalence and influence of combined version (CV) abnormalities.
Purpose: To (1) describe the distribution of AV, FV, and CV in the largest cohort to date and (2) determine the relationship between AV, FV, and CV and PROs after hip arthroscopy for FAIS.
Study Design: Cohort study; Level of evidence, 3.
12-year cumulative incidence rate of rare retinal diseases: a nationwide study in Korea.
Eye (Lond)
January 2025
Department of Ophthalmology, Chung-Ang University, College of Medicine, Seoul, South Korea.
Purpose: Understanding the incidence of rare diseases is important in establishing a proper public health care system and setting target diseases in medical research. Herein, we report the 12-year cumulative incidence of seven rare ocular diseases of the retina in South Korea.
Methods: We analysed clinical records of 1,126,250 South Korean population during 2006~2019.
Mapping the neural substrate of high dual-task gait cost in older adults across the cognitive spectrum.
Brain Struct Funct

Department of Medical Biophysics, Schulich School of Medicine & Dentistry, Western University, 1151 Richmond Street, North London, ON, N6A 5C1, Canada.
The dual task cost of gait (DTC) is an accessible and cost-effective test that can help identify individuals with cognitive decline and dementia. However, its neural substrate has not been widely described. This study aims to investigate the neural substrate of the high DTC in older adults across the spectrum of cognitive decline.

ProCardio Center for Innovation, Department of Cardiology, Oslo University Hospital, Oslo, Norway.
Background: Although anthracycline-related cardiotoxicity is widely studied, only a limited number of echocardiographic studies have assessed cardiac function in breast cancer survivors (BCSs) beyond ten years from anthracycline treatment, and the knowledge of long-term cardiorespiratory fitness (CRF) in this population is scarce. This study aimed to compare CRF assessed as peak oxygen uptake (V̇O), cardiac morphology and function, and cardiovascular (CV) risk factors between long-term BCSs treated with anthracyclines and controls with no history of cancer.
Methods: The CAUSE (Cardiovascular Survivors Exercise) trial included 140 BCSs recruited through the Cancer Registry of Norway, who were diagnosed with breast cancer stage II to III between 2008 and 2012 and had received treatment with epirubicin, and 69 similarly aged activity level-matched controls.
