الوصف: This is the first report of the reproductive performance of rams in a flock of “Obispo” sheep. The study was carried out ex situ (18°15'52"’ LN) in higher temperature conditions than what occurs in the Guerrero Mountain, Mexico. In the Principal Components analysis (CP), the first component (CP1) included body weight (BW), scrotal circumference (SC) and ejaculate volume (EV), in CP2 it grouped sperm concentration (SPC) and progressive motility (PM). SC showed an increase throughout the year reaching 32.0 ± 0.3 centimeters at the end of the study at an approximate age of 30 months and showed correlations greater than 0.5 with EV, SPC, PM. The lowest values recorded in the characteristics were in the spring, with 0.86 ± 0.3 mililiters (mL) for EV 4,120.2 ± 162 million sperm·mL-1 × 106 for SPC and 86 ± 1.6% for PM; while the highest values were presented in autumn with 1.12 ± 0.02 mL for EV, 4,519.2 ± 187.0 million spermatozoa·mL-1 × 106 for SPC and 92.0 ± 1.1% for PM. The rams maintain a high libido that allows them to maintain a high number of services (more than three in a period of five minutes), with reduced reaction times 49 second and recovery between copulations (1.84 minutos). ; Este es el primer reporte del comportamiento reproductivo de los carneros en un rebaño de ovinos “Obispo”. El estudio se llevó a cabo ex situ (18°15'52" LN) en condiciones de mayor temperatura de lo que se presenta en la montaña de Guerrero, México. En el análisis de Componentes principales (CP), el primer componente (CP1) incluyó el peso corporal (PC), circunferencia escrotal (CE) y volumen de eyaculado (VE) y, en el CP2, se agrupó la concentración espermática (CONC) y motilidad progresiva (MP). La CE mostró un incremento a través del año llegando al final del estudio a 32,0 ± 0,3 centímetros a una edad aproximada de 30 meses y mostró correlaciones mayores a 0,5 con VE, CONC y MP. Los valores más bajos registrados en las características fueron en la primavera, con 0,86 ± 0,3 milílitros (mL) para el VE, 4.120,2 ± 162 millones de ...

مصطلحات موضوعية: hypertension, body mass index, abdominal circumference, hipertensión, índice de masa corporal, circunferencia abdominal
الوصف: The present study had the purpose of evaluating the proportion of subjects with hypertension, treatment, control rates, and the relationship between blood pressure (BP) with body mass index and abdominal circumference in a cross-sectional study, as part of a worldwide study designed by International Society of Hypertension, performed during May 2017. After the protocol´s approval by the local Ethical Committee, 64 sites were included from eight Venezuelan regions. A short questionnaire was completed for each participant, including knowledge of taking antihypertensive treatment, diabetes, previous myocardial infarction or stroke, alcohol intake, and smoking. BP was measured in the sitting position three times after resting for 5 minutes, one minute apart, using mainly oscillometric devices. Height, weight and abdominal circumference were measured. Data analyses were performed by the MMM central team. 21644 individuals were screened. After multiple imputations, 10584 individuals [48.9% (50.7% male; 47.7% female)] had hypertension. Of subjects not receiving antihypertensive medication, 1538 (12.2%) were hypertensives. Of hypertensive individuals receiving antihypertensive medication, 2974 (32.9%) had uncontrolled BP. 15.6% of our sample had obesity according to their body mass index; 43.8% of women and 20.7% of men had abdominal obesity. BP was positively correlated with BMI and abdominal circumference. In this largest BP screening carried out in Venezuela, 48.9% of the individuals had elevated BP and 12.2% did not know that they had hypertension, and in one third of those with hypertension on treatment, BP was not controlled. 15.6% had obesity by BMI, and 35.1% abdominal obesity. Screening such as the MMM17 can evaluate the association between hypertension and obesity and therefore may help to inform control programs.Resumen. Se realizó el presente estudio con el objetivo de evaluar la proporción de sujetos con hipertensión, tratamiento, tasas de control y la relación entre la presión arterial (PA) con ...

مصطلحات موضوعية: metabolic syndrome, abdominal obesity, central obesity, waist circumference, cut-off values, obesity // síndrome metabólico, obesidad abdominal, obesidad central, circunferencia de la cintura, obesidad
الوصف: Waist circumference has been commonly used as a simple and clinically useful representative marker for central adiposity. The aim of this study was to investigate the optimal cut-off measurement of waist circumference of an Erbil population for diagnosing abdominal obesity. A cross sectional study was conducted in Erbil city. A total of 800 adult men and women (≥18year) of 800 different families were selected using a stratified multistage probability random sampling. Central obesity was defined according to the International Diabetes Federation criteria. Data was analyzed by using the statistical package for the social science, version 22. Receiver Operating Characteristic curves is designed to determine the cut-off point for waist circumference for both genders. A p value ≤ 0.05 was regarded as statistically significant. The cut-off value for male using the Receiver Operating Characteristic ROC curve was 94.7cm (sensitivity 82%, specificity 32%).The cut-off vale for female using the ROC curve was 97cm (sensitivity 55%, specificity 67%). We report a high prevalence of metabolic syndrome and abdominal obesity, especially in women, among the Erbil population. We recommend that these WC cut-off values be integrated into local preventive policies for public health, as the local criteria for diagnosing abdominal obesity, metabolic syndrome and related diseases.ResumenLa circunferencia de la cintura se ha usado comúnmente como un marcador representativo simple y clínicamente útil para la adiposidad central. El objetivo de este estudio fue investigar la medida de corte óptima de la circunferencia de la cintura de la población de Erbil para diagnosticar la obesidad abdominal. Se realizó un estudio transversal en la ciudad de Erbil. Un total de 800 hombres y mujeres adultos (≥18 años) de 800 familias diferentes se seleccionaron mediante un muestreo aleatorio estratificado de múltiples etapas de probabilidad. La obesidad central se definió de acuerdo con los criterios de la Federación Internacional de Diabetes. ...
