The density of HRN per 100,000 inhabitants was estimated, based on the total population, and its distribution was analyzed according to social security institution, level of care, and federative entity. In addition, the density of HRN for adults with overweight or obesity (OoO) was estimated for 2023. To estimate the inequality in the state distribution of HRN, the concentration index (CI) was used, and the marginalization index as a stratifier.Results: In Mexico, the density of HRN increased from 5.9 in 2019 to 6.9 per 100,000 inhabitants in 2023; however, this increase was unequal among federative entities, institutions, and levels of care. In second and third-level care units, the density reached up to 22.41 HRN per 100,000 inhabitants, while in the first level it was 2.0. There is a higher concentration of HRN in entities with lower marginalization (CI=0.13 in 2019; CI=0.11 in 2023), units for the population with social security (CI=0.36 in 2019; CI=0.33 in 2023), and second and third levels (CI=0.20 in 2019; CI=0.18 in 2023).Conclusions: In Mexico, between 2019 and 2023, the density of HRN increased, but state-level and by level of care inequalities persist. Strengthening its planning and distribution, particularly at the first level of care, is essential to respond to the nutritional and epidemiological needs of the country.","PeriodicalId":53651,"journal":{"name":"Revista Peruana de Medicina de Experimental y Salud Publica","volume":"43 3","pages":"338-348"},"PeriodicalIF":1.1,"publicationDate":"2026-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149186199","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The urinary arsenic concentration was determined by inductively coupled plasma mass spectrometry (ICP-MS) and adjusted for creatinine; high exposure was defined as a concentration ≥20 μg As/g of creatinine. Sociodemographic and occupational characteristics, epidemiological history of exposure, and environmental factors were evaluated as potential associated factors. Adjusted prevalence ratios (aPR) with 95% confidence intervals (95% CI) were estimated using Poisson regression models with a log link.Results: The prevalence of high arsenic exposure was 68.2% (95% CI: 61.9-73.9). Exposure at work was associated with a higher prevalence of high arsenic (aPR 1.29; 95% CI: 1.07-1.56), as was the consumption of spring water (aPR 1.19; 95% CI: 1.01-1.40). Exposure at home (aPR 0.83; 95% CI: 0.69-0.99) and the respiratory route (aPR=0.82; 95% CI: 0.72-0.92) showed a lower prevalence of high arsenic.Conclusions: The adult population of Chumbivilcas presented a high prevalence of arsenic exposure. Exposure at work and the use of spring water were associated with a higher prevalence.

Sarcopenia was assessed using the criteria established by the Asian Working Group for Sarcopenia, which include the measurement of muscle strength, muscle mass, and physical performance; and functionality, using the Barthel scale. In addition, sociodemographic and anthropometric characteristics, as well as medical and personal history, were included. A Poisson regression analysis with robust variance was performed to es-timate crude and adjusted prevalence ratios (PR), with their respective 95% confidence intervals (95%CI).Results: A total of 315 older adults were included in the analysis, of whom 193 (n=61.3%) were women. It was found that 113 (n=35.9%) presented sarcopenia and 115 (n=36.5%) had functional dependence. In the adjusted Poisson regression analysis, it was found that sarcopenia was significantly associated with a higher probability of functional dependence (PR=1.43; 95%CI: 1.05-1.95). Furthermore, frailty (PR=2.07; 95%CI: 1.27-3.38), subjective memory complaint (PR=1.40; 95%CI: 1.02-1.91), and hearing loss (PR=1.53; 95%CI: 1.09-2.14) were also factors associated with greater functional dependence.Conclusions: In rural Ama-zonian communities, sarcopenia in older adults is associated with functional dependence.

On the fourth day, he presented sudden headache and loss of consciousness; tomography revealed hemorrhage in the fourth ventricle. The second case corresponds to a five-year-old child who received traditional medicine and whose first dose of antivenom was administered after four days of the bite, following a prolonged fluvial transfer. He presented severe anemia, altered sensorium, and hemorrhage in the left lateral ventricle. Both patients required intensive care, additional antivenom, and supportive measures, and were discharged without neurological deficit. These cases illustrate that delayed or insufficient access to antivenom in the Amazon can be associated with hemorrhagic complications of the central nervous system.","PeriodicalId":53651,"journal":{"name":"Revista Peruana de Medicina de Experimental y Salud Publica","volume":"43 3","pages":"408-414"},"PeriodicalIF":1.1,"publicationDate":"2026-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149186166","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the 22 mothers with paired samples, the mean concentration was 7.71 ± 2.27 mg/mL in transitional milk and 3.76 ± 1.06 mg/mL at 2 months.

Global seroprevalence was estimated and stratified by sex, age group, and origin.Results: After data expansion, 53.6% of the studied population corresponded to women. The global seroprevalence was 82.1% (95% CI: 78.6%-85.1%). Adults aged 20 to 29 years showed the lowest seroprevalence (55.6%), followed by adolescents aged 15 to 19 years (72.0%). Seroprevalence progressively increased with age and exceeded 95% in people aged 50 years or older. No significant differences were observed by sex or area of origin.Conclusions: Immunity gaps against measles are evident mainly in young adults, in a context of disease resurgence in the Americas and an ongoing outbreak in Peru. These findings highlight the value of seroprevalence studies to identify susceptible groups and guide public health interventions, such as targeted vaccination strategies, strengthening epidemiological surveillance, and information campaigns to reduce immunity gaps and contribute to maintaining measles elimination in Peru.","PeriodicalId":53651,"journal":{"name":"Revista Peruana de Medicina de Experimental y Salud Publica","volume":"43 3","pages":"301-310"},"PeriodicalIF":1.1,"publicationDate":"2026-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149186302","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
