Background: There is an increase in the incidence of malignant melanoma in Chile. Previous studies have shown that the density and size of acquired melanocytic nevi (AMN) are a risk factor for developing malignant melanoma.
Aim: To assess the number and anatomical distribution of acquired melanocytic nevi in Chilean adolescents.
Material And Methods: The number of AMN was counted in 30 anatomical sites in 201 Chilean school children (111 females), aged from 11 to 15 years. The number of small AMN (2-4.9 mm) and large AMN (>5 mm of diameter) was determined.
Results: Mean AMN number per person was 32.7 (95% confidence interval (CI) 30.7-42.3) in males and 29 (95% CI 271-38.6) in females (p =NS). Males had a higher number of AMN in the face, neck and trunk. Females had a higher number of AMN in the upper and lower limbs. Older children, adolescents with history of sunburns and with lighter skin had a higher number of total, small and large nevi.
Conclusions: The average number of AMN found in this study is similar to that reported in the literature. The differences in site distribution between males and females may be explained by a different sun exposure pattern.

Background: Exergames are interactive technology-based exercise programs. By combining physical and cognitive training components, they aim to preserve independence in older adults and reduce their risk of falling. This study explored whether primary end users (PEU, healthy older adults and patients with neurological and geriatric diagnoses) and secondary end users (SEU, health professionals) evaluated the ExerG functional model to be usable, providing a positive experience and therefore acceptable.

To explore the hypothesis that knee osteoarthritis patients with osteoporosis represent a sub-cohort with different disease characteristics and origin of symptoms. Men and women in the Osteoarthritis Initiative (OAI) at visit 5 (36 months) were examined for osteoporosis (N = 1483) using DXA (T-score at femoral neck ≤ -2.5), use of bisphosphonates, or having experienced a fracture.

Introduction: Courier delivery has become a popular antiretroviral therapy (ART) distribution method in some HIV care settings, yet data on ART courier delivery and how it relates to ART outcomes are scarce. We studied the differences in viral suppression rates between individuals from a South African private sector HIV programme receiving ART by courier delivery and those receiving ART through traditional retail dispensing.
Methods: Individuals aged 15 years or older who were actively enrolled in the Aid for AIDS programme between January 2011 and July 2022 were eligible for the analysis.

An AA'BO-type perovskite oxide PbMn(CrMn)O was synthesized by high-pressure solid-state reactions at 8 GPa and 1373 K. Synchrotron X-ray diffraction shows a cubic crystal structure with the space group 3̄. The charge states are verified by X-ray photoelectron spectroscopy to be PbMn(CrMnMn)O, where the Pb and Mn are 1 : 3 ordered respectively at A and A' sites, while the Cr, Mn and Mn are disorderly distributed at the B site.
