Objective: To determine the degree of knowledge about warfarin treatment in patients with atrial fibrillation or with mechanical prosthetic valves., Materials and Methods: Descriptive, observational, cross-sectional study. The OAK test was applied to all adult patients with a diagnosis of atrial fibrillation or with mechanical prosthetic valves treated with warfarin, who attended the hematology consultation from May 17 to November 10, 2022, at the "Instituto Nacional Cardiovascular Carlos Alberto Peschiera Carrillo"., Results: A total of 150 patients participated, 64% were male, with a mean age of 60.3 ± 15 years, 45.3% with a diagnosis of atrial fibrillation and 54.7% with mechanical prosthetic valves. The mean OAK test score was 44.4% (8.4/19), only 6% (n=9) achieved a satisfactory score ≥75.0%, the percentage of correct answers according to dimensions was: 68 % in forms of use, 39.3% in interactions and complications and 41.1% in INR control. A 40.7% did not understand the meaning of the term INR and 81.3% did not know their optimal values., Conclusions: The patient's degree of knowledge about warfarin treatment was inadequate; both in its use, interactions and complications. Considering that it is a difficult drug to use, due to its narrow therapeutic window and its multiple interactions, inadequate knowledge of its use may contribute to inappropriate anticoagulation., Competing Interests: Conflictos de interés: Ninguno

The aim of the study was to explore the patterns of dental health services access in children under twelve years of age in Peru. Data from 25,285 children under 12 years who participated in the Demographic and Family Health Survey of 2014 were reviewed. An exploratory spatial analysis was performed to project the proportions of children with access to dental health services, according to national regions, type of health service and urban or rural place of residence. The results show that of the total sample, 26.7% had access to dental health services in the last six months, 39.6% belonged to the age group 0-4 years, 40.6% lived in the Andean region and 58.3% lived in urban areas. The regions of Huancavelica, Apurimac, Ayacucho, Lima and Pasco had the highest percentages of access nationwide. In conclusion, there is low access to dental health services in the population under 12 years of age in Peru. The spatial distribution of access to dental health services allows regions to be identified and grouped according to similar access patterns, in order to better focus public health actions.

Objectives.: To estimate regional prevalence and identify the spatial patterns of the degree of overweight and obesity by districts in under five years children in Peru during 2014., Materials and Methods.: Analysis of the information reported by the Information System Nutritional Status (SIEN) of the number of cases of overweight and obesity in children under five years recorded during 2014. Regional prevalence for overweight and obesity, and their respective confidence intervals to 95% were calculated. Moran index was used to determine patterns of grouping districts with high prevalence of overweight and/or obesity., Results.: Data from 1834 districts and 2,318,980 children under five years were analyzed. 158,738 cases (6.84%; CI 95%: 6.81 to 6.87) were overweight, while 56,125 (2.42%; CI 95%: 2.40 to 2.44) obesity. The highest prevalence of overweight were identified in the regions of Tacna (13.9%), Moquegua (11.8%), Callao (10.4%), Lima (10.2%) and Ica (9.3%), and in the same regions for obesity with 5.3%; 4.3%; 4.0%; 4.0% and 3.8% respectively. The spatial analysis found grouping districts of high prevalence in 10% of all districts for both overweight and obesity, identifying 199 districts for overweight (126 urban and 73 rural), and 184 for obesity (136 urban and 48 rural)., Conclusions.: The highest prevalence of overweight and obesity were identified in the Peruvian coast regions. Moreover, these regions are predominantly exhibited a spatial clustering of districts with high prevalence of overweight and obesity.

In order to determine the potential vulnerability of public health facilities in four northern regions of Peru to the possible effects of El Niño-Southern Oscillation (ENSO) phenomenon. An exploratory spatial analysis was performed using the geo-referenced points for at-risk areas based on the activation of gullies that were reported by the National Water Authority, and the location of the four regional public health facilities of the Ministry of Health. Concentric areas of influence were simulate from the points of risk towards the public health facilities using radii of 200, 1000 and 1500 meters. The Tumbes region would be the most affected with 37.2% of its health facilities being affected by floods and landslides. The I-2 and I-3 categories of health facilities appeared to be the most affected with 28.9% and 31.6% respectively. Therefore, public health facilities near the risk zones may be affected by the ENSO.

We analyzed geospatially accidents, incidents and diseases related to work of regional reports in Peru (2012-2014). The 52887 events were classified as work related accidents (93%), dangerous incidents (5.1%), occupational diseases (1%) and fatal accidents (0.9%). The highest rates of fatal accidents were reported in Pasco, Callao, Lima, Moquegua and Arequipa. Callao and Lima are the regions with the highest rates of occupational accidents. The highest rates of dangerous incidents were reported in Arequipa, Callao, Lima, Ica and Piura. Occupational diseases are distributed with high rates in Huancavelica, Ancash, Pasco, Callao and Cusco. The economic activities that reported most of the occupational diseases were mining and quarrying (49.2%); followed by manufacturing industry (23.4%); and construction (8%). It is concluded that there are high rates and common spatial patterns of laboral accidents in Peru that could be used by decision makers to focus interventions.
