    BACKGROUND: University teachers, as agents of socialization, are one of the most influential groups in improving public health, and their nutritional knowledge can influence both the eating behavior of students and the family. OBJECTIVE: This study was carried out to evaluate the effect of a telehealth program on the level of nutritional knowledge and body mass index (BMI) of university teachers. METHODS: A pre-experimental study was carried out from August to December 2020. A pretest and a posttest were applied. The number of teachers in the initial test was 88 and those included in the final evaluation, 83; and they were selected by nonprobability sampling for convenience. The telehealth-based program lasted 18 weeks and included basic information on nutrition and motivational messages. Sociodemographic and anthropometric data were collected through a predesigned questionnaire before and after the educational program. RESULTS: < .001) before and after the intervention program. CONCLUSION: The telehealth-based intervention improved basic nutritional knowledge levels and BMI. Likewise, the current findings provide evidence on the importance and need to develop future nutritional education programs that comprehensively encompass all study plans for the benefit of the university community.

    Elaborar una escala válida y fiable para medir el rol del profesional de enfermería en la comunidad (REFCO). Estudio observacional con diseño transversal de tipo instrumental. Centros poblados y comunidades de la Costa, Sierra y Selva del Perú. La fase de validación del cuestionario contó con la participación voluntaria de 402 adultos peruanos (50,7% de la costa, 40,5% de la sierra y 8,8% de la selva). Se aplicó el cuestionario elaborado que mide las percepciones sobre la escala REFCO. Se analizaron las propiedades psicométricas de la escala REFCO, tales como la validación de contenido y consistencia interna a través del cálculo de V de Aiken, análisis factorial exploratorio (AFE) y posteriormente análisis factorial confirmatorio (AFC), respectivamente. Finalmente, se calculó la confiabilidad de la escala. Todos los valores fueron estadísticamente significativos cuando se evaluaron con el coeficiente de V-Aiken. Asimismo, los valores de asimetría y curtosis de todos los ítems del instrumento no exceden el rango > ± 1,5. Las correlaciones entre el factor 1 y 2 fueron significativas (p <,05). La confiabilidad de la escala presenta un coeficiente α de Cronbach = 0,865. La escala REFCO posee nueve ítems y dos dimensiones, salida al campo y educación, con validez de contenido y constructo que proporcionan evidencia para categorías de enfermería comunitaria, siendo útil para medir la labor de la misma en el campo comunitario. To develop a valid and reliable scale to measure the role of the nursing professional in the community (REFCO). Observational with cross-sectional and instrumental design. Populated centers and communities of the coast, highlands and jungle from Peru. The validation phase of the questionnaire had the voluntary participation of 402 Peruvian adults (50.7% from the coast, 40.5% from the highlands and 8.8% from the jungle). The elaborated questionnaire that measures perceptions about the role of the nursing professional in the community was applied. The psychometric properties of the REFCO scale were analyzed, such as content validation and internal consistency through the calculation of Aiken's V, exploratory factor analysis (EFA) and later confirmatory factor analysis (CFA), respectively. Finally, the reliability of the scale was calculated. Overall, all values were statistically significant when evaluated with the V-Aiken coefficient. Likewise, the skewness and kurtosis values of all the items of the instrument did not exceed the range >±1.5. The correlations between factors 1 and 2 were significant (p < .05). The reliability of the scale presents a Cronbach's α coefficient = 0.865. The REFCO scale has 9 items and 2 dimensions; outreach and education; with content and construct validity that provide evidence for community nursing categories, which is useful for measuring nursing work in the community field.

    Several studies have been carried out which mainly focus on the analysis of the lipid profile in vegetarians and nonvegetarians. However, few studies have been undertaken in this population oriented to quality of life and health. This study aimed to compare health-related quality of life, blood pressure, and biochemical and anthropometric profile in vegetarians and nonvegetarians. The study included 149 participants out of an initial sample of 162: 62 vegetarians and 87 nonvegetarians. Health-related quality of life was assessed with the SF-12 Health Questionnaire version 2 and was related with the lipid profile, glucose, blood pressure, anthropometric measures, and sociodemographic characteristics. Vegetarians presented better Body Mass Index (BMI) and waist circumference (WC), as well as higher LDL levels. No significant differences in HDL and TG concentrations were found. Serum glucose concentrations were significantly lower among vegetarians. Nonvegetarian males had higher diastolic pressure levels. Vegetarian women had significantly higher levels of systolic pressure. As for the physical health and mental health components of quality of life, no significant differences were found in vegetarian and nonvegetarian women and men. In conclusion, vegetarians presented a better anthropometric profile, lower glycaemia, and higher LDL levels but no significant differences in health-related quality of life compared with nonvegetarians.

    El cuestionario Cultura de retroalimentación en educación médica es una escala validad que determina la percepción de la cultura de retroalimentación en países de habla inglesa. El objetivo de este trabajo es validar este cuestionario en su versión española en estudiantes de medicina peruanos durante una rotación clínica. Un estudio observacional, analítico de tipo instrumental fue realizado en 139 estudiantes de medicina. La validez de la escala fue determinada por V-de-Aiken e intervalos de confianza. Se realizaron pruebas de análisis factorial y alfa de Cronbach. Todos los valores fueron estadísticamente significativos cuando se evaluaron con el coeficiente V-de-Aiken. Además, la asimetría y curtosis de todos los ítems son adecuados ya que no exceden el rango >± 1.5. La significancia de la prueba de esfericidad de Barlett (1521.8; gl = 120; p = 0.001) y el coeficiente Kaiser Meyer-Olkin (KMO = .953) fueron adecuados y el análisis factorial exploratorio reveló una estructura de dos factores. El coeficiente α de Cronbach de la escala total y sus factores, fue superior a 0,80. El cuestionario Cultura de retroalimentación en educación médica en español es una escala válida para evaluar la percepción sobre la cultura de retroalimentación en estudiantes de medicina que están realizando rotación clínica. The Feedback-Culture in Medical Education questionnaire is a validated scale to determine students’ perceptions of feedback culture in English-speaking countries. The objective of this work is to validate this questionnaire in its Spanish language version for Peruvian medical students during a clinical rotation. An observational, instrumental-type analytical study was conducted on 139 medical students. The validity of the scale was determined by means of the Aiken's V coefficient and confidence intervals. Factorial analysis tests and Cronbach's alpha were performed. All values were statistically significant when evaluated with Aiken's V coefficient. In addition, the asymmetry and kurtosis of all items are adequate as they do not exceed the range >±1.5. The significance of the Barlett sphericity test (1521.8; gl = 120; p = 0.001) and the Kaiser Meyer-Olkin coefficient (KMO = .953) were adequate and exploratory factor analysis revealed a two-factor structure. Cronbach's α coefficient of the total scale and its factors was higher than 0.80. The Feedback-Culture in Medical Education – Spanish questionnaire is a valid scale to evaluate the perception about feedback culture in medical students who are doing a clinical rotation.

    This work reports the purification and biochemical and functional characterization of ACP-TX-I and ACP-TX-II, two phospholipases A2 (PLA2) from Agkistrodon contortrix pictigaster venom. Both PLA2s were highly purified by a single chromatographic step on a C18 reverse phase HPLC column. Various peptide sequences from these two toxins showed similarity to those of other PLA2 toxins from viperid snake venoms. ACP-TX-I belongs to the catalytically inactive K49 PLA2 class, while ACP-TX-II is a D49 PLA2, and is enzymatically active. ACP-TX-I PLA2 is monomeric, which results in markedly diminished myotoxic and inflammatory activities when compared with dimeric K49 PLA2s, confirming the hypothesis that dimeric structure contributes heavily to the profound myotoxicity of the most active viperid K49 PLA2s. ACP-TX-II exhibits the main pharmacological actions reported for this protein family, including in vivo local myotoxicity, edema-forming activity, and in vitro cytotoxicity. ACP-TX-I PLA2 is cytotoxic to A549 lung carcinoma cells, indicating that cytotoxicity to these tumor cells does not require enzymatic activity.

    Risk behaviors in schoolchildren can negatively influence and affect their wellbeing. Therefore, it is necessary to have a validated tool to measure student satisfaction in specific areas of the school. The objective of this study was to adapt to Spanish and evaluate the psychometric properties of the H-Sat Scale in Peruvian students. The participants were 691 high school students between 11 and 18 years old ( M = 13.96, SD 1.38) who were administered the H-Sat Scale. The scale was translated into Spanish (H-SatP Scale) using the forward and backward method. The scale presented adequate internal consistency for each of the five factors (ordinal α, CR, ω, and H &amp;gt; 70). Confirmatory analysis confirmed the five-dimensional structure (χ 2 = 620.864, df = 160; CFI = 0.982, TLI = 0.978, RMSEA = 0.065, SRMR = 0.032). This measurement tool could be used for the evaluation of interventions in school and health contexts to assess other aspects of wellbeing necessary for their development in school-age students.

    The present study evaluated the factors associated with the perception of anxiety during the first wave of covid-19 in Ibero-American countries. This cross-sectional study was carried out with 5.845 participants of both sexes, over 18 years of age, and residents of four Latin American countries-Argentina (16.7%), Brazil (34.5%), Mexico (11.1%), and Peru (17.5%), and one European country-Spain (20.1%). Data were collected in 2020, between April 1st and June 30th in Spain and between July 13th and September 26th in the Latin American countries. We used an online questionnaire with sociodemographic, lifestyle, self-reported anxiety, and covid-19 related questions. The chi-square statistical test and Multivariate logistic regressions were performed to analyze the factors associated with self-reported anxiety. The presence of self-reported anxiety was found in 63.8% of the participants during the isolation period. The association occurred mainly in women (OR:1.52; CI: 1.3-1.7), those aged 18 to 29 years (OR: 1.51; CI: 1.2-1.9) and 30 to 49 years (OR: 1.56; CI: 1.3-1.9), residents of Argentina (OR: 1.55 CI: 1.2-1.9), Brazil (OR: 2.38; CI: 2.0-2.8) and Mexico (OR: 1.52; CI: 1.2-1.9), those who gained weight (OR:1.71 CI: 1.5-1.9) or lost weight (OR: 1.40; CI: 1.2-1.6), and those who reported having slept more (OR: 1.56; CI: 1.3-1.8) or less (OR: 2.89; CI: 2.5-3.4). We conclude that the prevalence of self-reported anxiety in Ibero-American countries was high during the period studied, highlighting a higher likelihood of its occurrence in Brazil, in those who began to sleep less and gained weight.
