    Abstract: ABSTRACT Introduction: The role of p-value knowledge for clinical practice is elemental; however, insufficient evidence on this is found in health science students. Objective: To determine the factors associated with p-value knowledge in human medical students. Methods: Analytical cross-sectional study. Application of a virtual survey to human medicine students from different faculties in Peru. Results: 54.69% had sufficient knowledge of p-value. The multivariate analysis found a statistically significant association with having sufficient knowledge on this topic in those who were between 6th to 9th semester (APr: 1.118; 95% CI 1.051 - 1.412; p=0.009) and medical internship (APr: 1.234; 95% CI 1.073 - 1.418; p=0.003); taking an external course in biostatistics, epidemiology or research (APr: 1.420; 95% CI 1.227 - 1.643; p 〈 0.001); having read 6 to 12 articles per year (APr: 1.353; 95% CI 1.196 - 1.530; p 〈 0.001) and more than 12 articles per year (APr: 1.590; 95% CI 1.313 - 1.967; p 〈 0.001); and publishing at least one scientific article (APr: 1.397; 95% CI 1.199 - 1.628; p 〈 0.001) or more than one (APr:1.424; 95% CI 1.196 - 1.696; p 〈 0.001). Conclusion: It was found that the academic semester, having taken an external course, having read more than 6 articles per year and having published at least one scientific article are independently associated with having greater understanding of this topic.

    Abstract: Due to the increase in obesity worldwide, international organizations have promoted the adoption of a healthy lifestyle, as part of which fruit consumption stands out. However, there are controversies regarding the role of fruit consumption in mitigating this disease. The objective of the present study was to analyze the association between fruit intake and body mass index (BMI) and waist circumference (WC) in a representative sample of Peruvians. This is an analytical cross-sectional study. Secondary data analysis was conducted using information from the Demographic and Health Survey of Peru (2019–2021). The outcome variables were BMI and WC. The exploratory variable was fruit intake, which was expressed in three different presentations: portion, salad, and juice. A generalized linear model of the Gaussian family and identity link function were performed to obtain the crude and adjusted beta coefficients. A total of 98,741 subjects were included in the study. Females comprised 54.4% of the sample. In the multivariate analysis, for each serving of fruit intake, the BMI decreased by 0.15 kg/m2 (β = −0.15; 95% CI −0.24 to −0.07), while the WC was reduced by 0.40 cm (β = −0.40; 95% CI −0.52 to −0.27). A negative association between fruit salad intake and WC was found (β = −0.28; 95% CI −0.56 to −0.01). No statistically significant association between fruit salad intake and BMI was found. In the case of fruit juice, for each glass of juice consumed, the BMI increased by 0.27 kg/m2 (β = 0.27; 95% CI 0.14 to 0.40), while the WC increased by 0.40 cm (β = 0.40; 95% CI 0.20 to 0.60). Fruit intake per serving is negatively related to general body adiposity and central fat distribution, while fruit salad intake is negatively related to central distribution adiposity. However, the consumption of fruit in the form of juices is positively associated with a significant increase in BMI and WC.

    Abstract: The addition of melatonin in seminal extenders due to its antioxidant properties and its beneficial role in sperm preservation has been previously described, especially in seasonal species. The aim of this study was to study a potential seasonal effect based on photoperiod duration when adding a physiological concentration of melatonin in the canine ejaculate. A total of 24 ejaculates were obtained from 10 healthy dogs during the increasing photoperiod (from December 21 to June 21), whereas 12 ejaculates were collected from five healthy individuals during the decreasing photoperiod (from June 22 to December 20). Each ejaculate was separated into two aliquots, and one of them remained as a control, whereas melatonin (100 pM) was added to the other one (C and M treatment groups, respectively). Diluted semen was refrigerated at 5°C. On days 0, 1, 2, 3, and 6, sperm motility analyses were performed using a CASA system and hypoosmotic swelling test (HOST), osmotic resistance test (ORT), and flow cytometry analysis. No effect of melatonin on motility was detected in either photoperiod. Negative effects of melatonin were found for acrosomal defects, apoptosis, and viability in the decreasing photoperiod. The addition of melatonin to sperm in the decreasing photoperiod could create such a high level that it would cause the described negative effects. We found a beneficial effect of melatonin in the increasing photoperiod on acrosomal defects and apoptosis during 0–6 days. Melatonin treatment also increased viability in the short term (days 1 and 2) for both photoperiods. Also, melatonin can provide certain beneficial effects on mitochondrial activity in the medium term (days 2 and 3) in the decreasing photoperiod.

    Abstract: Introducción: La reducción del consumo de sal se ha identificado como una de las intervenciones prioritarias para prevenir las enfermedades no transmisibles a nivel mundial. Por ello, se recomienda que uno de los tres pilares para reducir su ingesta es reconocer el nivel de conocimientos, actitudes y prácticas relacionadas con el consumo de sal (CAP-sal). Objetivo: Determinar el nivel de CAP-sal y los factores asociados a estos en la población peruana. Materiales y métodos: Estudio transversal analítico realizado mediante encuesta virtual en población adulta peruana. Resultados: Se trabajó con una muestra de 918 sujetos. La proporción de participantes con conocimiento, actitudes y prácticas suficientes, fue del 54,58 %; 50,22 % y 40,31 %, respectivamente. Las variables que aumentan la probabilidad de tener un nivel suficiente de CAP-sal fueron el sexo femenino, la presencia de obesidad e HTA. Mientras que los antecedentes familiares y área de residencia lo fueron únicamente para conocimientos, el grado de instrucción para conocimientos y prácticas, y la actividad física tanto para actitudes como prácticas. Conclusiones: Tanto el nivel de conocimiento y actitudes fueron suficientes en la mitad de la muestra, pero las prácticas se encuentran por debajo de esta. Existen brechas que varían según las características sociodemográficas, como la edad, sexo, antecedentes de HTA, obesidad y realización de actividad física. Resultados que podrían apoyar la inclusión de la promoción de una nutrición saludable en la población peruana.

    Abstract: Introduction: Given the relationship between obesity and type 2 diabetes mellitus (T2DM) and hypertension, an indicator of body fat, A Body Shape Index (ABSI), has been considered to have apparent predictive power for these diseases. Objective: To determine the predictive power of the ABSI for DMT2 and hypertension in Peru through the analysis of the Demographic and Health Survey-2020 (ENDES-by its acronym in Spanish-2020). Methods: Cross-sectional analytical study of the ENDES-2020. The variables evaluated were ABSI, body mass index, high abdominal waist, waist-to-height ratio, body roundness index (BRI) and conicity index (COI). Areas under the curves (AUC) together with their 95% confidence interval (95%CI) were used to present each index. Results: A total of 19 984 subjects were studied. Regarding hypertension, the highest AUC was presented by the COI: AUC=0.707 (95%CI 0.694-0.719). While the ABSI obtained the penultimate place: AUC=0.702 (95% CI 0.689-0.715). In case of DM2, the highest ABC was presented by BRI: AUC=0.716 (95%CI 0.689-0.743); while ABSI obtained the second place: AUC=0.687 (95%CI 0.658-0.717). Conclusions: The results demonstrate that ABSI is not a good predictor for hypertension and DMT2 in the Peruvian population. If these findings are confirmed by other studies, its use would not be recommended for these diseases, and other anthropometric indicators that could perform better should be further explored.

    Abstract: Introducción: La Diabetes Mellitus tipo 2 es una enfermedad que representa un reto para la salud pública por su tendencia al crecimiento e impacto sobre todo en países en desarrollo. Objetivo: determinar los factores asociados a la no realización del cribado de diabetes mellitus tipo 2 según la encuesta demográfica y de salud familiar del año 2020 (ENDES-2020). Materiales y métodos: Estudio analítico transversal secundario de la ENDES-2020. Resultados: Las variables que mostraron asociación estadísticamente significativa para cribado de DM2 fueron: sexo masculino (PR=1,06, IC95% 1,02–1,10; p 〈 0,001), edad entre 30 a 59 años (0,92; IC95% 0,89–0,95; p 〈 0,001) y 60 años a más (PR=0,72; IC95% 0,65–0,79; p 〈 0,001), educación primaria (PR=0,94, IC 95% 0,92 - 0,99; p 〈 0,020), secundaria (PR=0,93; IC 95% 0,88–0,97; p=0,008) y superior (PR=0,86, IC 95% 0,85–0,94; p 〈 0,001), ser pobre (PR=0,96, IC95% 0,92–0,99; p=0,016), medio (PR=0,93; IC95% 0,88 – 0,96; p=0,001), rico (PR=0,89; IC95% 0,84 – 0,94; p 〈 0,001), muy rico (PR=0,81; IC95% 0,75–0,86; p 〈 0,001), e hipertensión (PR=0,91; IC 95% 0,867–0,969; p=0,002). Discusión: El sexo masculino fue el único factor asociado a la no realización del cribado de diabetes mellitus tipo 2, mientras que, pertenecer a un grupo de edad mayor, tener hipertensión arterial, mayor nivel educativo y socioeconómico aumentó la posibilidad de realizarlo. Conclusión: Es imprescindible reforzar las estrategias de cribado en el primer nivel de atención, mediante la implementación de medidas de prevención.

    Abstract: Introducción: El fibrinógeno plasmático, es reconocido como un factor de riesgo importante para eventos cardiometabólicos a través de mecanismos como la formación de trombina, agregación plaquetaria e inflamación, todos partes de la disfunción endotelial conducentes al Síndrome Coronario Agudo. Elevados niveles pueden estar presentes en sujetos con obesidad, sin embargo, no hay información suficiente sobre si esto también es igual en los sujetos delgados metabólicamente obesos (DMO). Objetivo: Determinar la asociación entre el DMO y niveles de fibrinógeno en una muestra de pobladores peruanos. Metodología: Estudio transversal analítico. Análisis de datos secundarios del estudio PERU MIGRANT (2007, 989 participantes). Para el diagnóstico de DMO se consideró si presentaba dos o más características de siete criterios metabólicos: circunferencia de la cintura (mediante evaluación antropométrica), triglicéridos, glucosa en ayunas, presión arterial sistólica y diastólica, colesterol-HDL, HOMA-IR, proteína C reactiva (PCR). Se consideró fibrinógeno (elevado ≥ 450 mg/dl). Para el análisis de regresión, se realizó un modelo lineal generalizado con enlace log y familia Poisson con varianza robusta. De esa forma, se obtuvo como medida de asociación las razones de prevalencia crudas (RPc) y ajustadas (RPa) por las covariables mencionadas, se consideró intervalos de confianza al 95% (IC 95%). Resultados: De los 393 participantes seleccionados, el 46,3% fueron mujeres, la mediana de edad fue 47(37–56), 13,5% presentó niveles de fibrinógeno elevado. La prevalencia de DMO fue 32,6%. Solo hubo una relación estadísticamente significativa entre fibrinógeno y el PCR-plasmático (rho= 0,54; p 〈 0,001). La regresión múltiple, encontró asociación entre el DMO y el nivel altos fibrinógeno plasmático (RP=1,93 IC95%: 1,44–2,57; p 〈 0,001). Conclusión: Existe asociación entre los niveles altos de fibrinógeno plasmático y el DMO. Estos resultados pueden servir para futuras investigaciones prospectivas, ya sea para considerarlo un factor de riesgo o como un marcador adicional para el seguimiento y diagnóstico en personas delgadas.

    Abstract: Introduction: Despite the growing awareness of the importance of knowledge in biostatistics, many investigations worldwide have found that medical students have a poor understanding of it. Objective: To determine the percentage of Peruvian medical students with sufficient biostatistics knowledge and the associated factors. Methods: Cross-sectional analytical study. Application of a virtual survey to medical students from different faculties in Peru. Results: 56.46% of medical students have insufficient knowledge of biostatistics. A statistically significant association was found for those who were 25 years of age or older (aPR: 1.195; 95% CI 1.045 - 1.366; p=0.009); being between the 9th and 12th semester (aPR: 1.177; 95% CI 1.001 - 1.378; p=0.037) and medical internship (aPR: 1.373; 95% CI 1.104 - 1.707; p=0.004); take an external course in biostatistics, epidemiology or research (aPR: 4.016; 95% CI 3.438 - 4.693; p 〈 0.001); having read more than 12 articles per year (aPR: 1.590; 95% CI 1.313 - 1.967; p 〈 0.001); and publish at least one scientific article (aPR: 1.549; 95% CI 1.321 - 1.816; p 〈 0.001) or more than one (PR: 2.312; 95% CI 1.832 - 2.919; p 〈 0.001). Conclusions: There is insufficient knowledge of biostatistics in medical students. The factors associated with a good understanding of this were age, academic semester, the number of articles read and published, and having taken an external course.

    Abstract: Protocols for fixed‐time artificial insemination (FTAI) in swine reproduction can help increase genetic improvement and production efficiency. Different gonadotropin‐releasing hormone (GnRH) agonists have been developed to gain better control of follicular development, timing, and ovulation quality; therefore, they have been extensively used in FTAI protocols. This literature review resumes the most important characteristics of the physiology of follicular development and ovulation in sows, followed by a discussion about the hormonal alternatives available to induce ovulation (human chorionic gonadotropin, hCG; porcine luteinizing hormone, LH and GnRH agonists). Also, ovulation induction failures with GnRH agonists are described. Finally, current FTAI protocols with GnRH agonists are resumed and discussed. FTAI with GnRH agonists has proven to be an efficient, successful reproductive protocol that can be implemented in pig farms due to better knowledge of an endocrine system that regulates follicular development and ovulation and increased availability of several GnRH agonists that allow more efficient reproductive swine programs.
