Bovines infected by bovine leukemia virus (BLV) are characterized by presenting low proviral load (LPL) or high proviral load (HPL). It is reported that animals with HPL in peripheral blood mononuclear cells (PBMCs) present a decrease in apoptosis, an increase in viability and the proliferation rate, while animals that maintain an LPL have an intrinsic ability to control the infection, presenting an increased apoptosis rate of their PBMCs. However, there is little information on the effect of BLV on these mechanisms when the virus infects somatic milk cells (SC). This study investigates the mechanisms underlying apoptosis in milk and blood from BLV-infected animals with HPL and LPL. Relative levels of mRNA of tumor necrosis factor-α (TNF-α), TNF receptor 1 (TNF-RI), TNF receptor 2 (TNF-RII), anti-apoptotic B-cell lymphoma 2 protein (Bcl-2), and pro-apoptotic Bcl-2-like protein 4 (Bax) were measured in SC and PBMCs using quantitative reverse transcription-polymerase chain reaction (RT-qPCR) assay. A significant decrease in the expression of TNF-α in SC from HPL animals vs non-infected bovines was observed, but the infection in SC with BLV did not show a modulation on the expression of TNF receptors. A significant increase in TNF-RI expression in PBMCs from HPL bovines compared to LPL bovines was observed. No significant differences in PBMCs between HPL and LPL compared to non-infected animals concerning TNF-α, TNF-RI, and TNF-RII expression were found. There was a significant increase of both Bcl-2 and Bax in SC from LPL compared to non-infected bovines, but the Bcl-2/Bax ratio showed an anti-apoptotic profile in LPL and HPL bovines compared to non-infected ones. Reduced mRNA expression levels of Bax were determined in the PBMCs from HPL compared to LPL subjects. In contrast, BLV-infected bovines did not differ significantly in the mRNA expression of Bax compared to non-infected bovines. Our data suggest that the increased mRNA expression of Bax corresponds to the late lactation state of bovine evaluated and the exacerbated increase of mRNA expression of Bcl-2 may be one of the mechanisms for the negative apoptosis regulation in the mammary gland induced by BLV infection. These results provide new insights into the mechanism of mammary cell death in HPL and LPL BLV-infected bovine mammary gland cells during lactation.

Paciente acude a la farmacia comunitaria por un trastorno del sueño solicitando tratamiento. Se indica Melatonina tras presentar insomnio clínico moderado en el Insomnia Severity Index. Pese a que 2 semanas después del principio del tratamiento refirió estar mejor, 2 meses después deja de ser así. Al realizar un seguimiento se sospecha de la existencia de problemas relacionados con los medicamentos por lo que se le deriva al servicio de Revisión de Uso de los Medicamentos. En dicho servicio se detectan varios problemas con su medicación habitual. Entre ellos, se detecta una confusión entre cápsulas de cafeína pertenecientes a su nieto con el que convive y el producto indicado en el servicio de indicación farmacéutica. Gracias al seguimiento del servicio de indicación farmacéutica se ha producido una derivación que ha solventado varios problemas relacionados con los medicamentos. (AU)

Abstract Introduction: Nurses frequently face different events associated with stress, psychosocial factors, and other issues which have impacts on their mental health. Objective: To assess the correlation between psychological demand, work control, social support, psychological stress, and burnout dimensions (illusion for the activity, psychic wear, indolence, guilt), within a model of trajectories among Mexican nurses. Methodology: This is a transversal, observational, and analytical study conducted on a convenience sample of 357 nursing professionals from the state of Morelos, Mexico. Data were gathered using three questionnaires, the Perceived Stress Scale, the Job Content Questionnaire, y el Maslach Burnout Inventory. SPSS 19 and LISREL 8.3 were used to process and model the data. Results: Psychological Stress was specified as the mediating variable of the psychosocial factors and dimensions of burnout within the model of trajectories. Adjustment indexes were acceptable. High levels of social support, work control, and illusion for the activity were found. Moderate degrees of psychological demand and psychological stress were found. Low levels of psychic wear, indolence, and guilt were found. Conclusion: It is recommended to implement effective intervention strategies to maintain nursing personnel within low levels of psychological demand, high levels of work control, high levels of social support, and moderate levels of stress, all these in order to prevent the Syndrome of Burnout.

RESUMO
Objetivo Evaluar la reproducibilidad intra e interevaluador de la Escala Motriz del Infante de Alberta (AIMS), Canadá, aplicada por fisioterapeutas en formación de último nivel. Materiales y métodos Se realizó un estudio de evaluación de pruebas diagnósticas en 21 infantes clínicamente sanos de ambos géneros, entre 0 y 18 meses residentes de la ciudad de Bucaramanga, Colombia. La evaluación fue realizada por 12 evaluadores, 11 fisioterapeutas en formación de último nivel y un fisioterapeuta con experiencia en el área pediátrica, con un intervalo de una semana y mediante vídeo. El análisis de reproducibilidad intra y entre evaluadores se estableció con el coeficiente de correlación intraclase (CCI) y adicionalmente se calculó el error estándar de la medición (EEM), considerando un α=0,05.ResultadosSe encontró una muy buena reproducibilidad interevaluadores para el puntaje total de la escala (CCI>0,98) y para la subescala en sedente (CCI>0,97). El análisis para las otras subescalas mostró CCI moderados entre 0,54 y 0,64. La reproducibilidad intraevaluador registró coeficientes entre bajos y excelentes. El EEM fue bajo para las subescalas de pie, en prono y el puntaje total (0,20-0,77).Conclusiones La AIMS es un instrumento reproducible, que puede ser utilizado en nuestro contexto por fisioterapeutas en formación para la evaluación del desarrollo motor en niños clínicamente sanos (AU)
Objective To evaluate the intra- and inter-rater reliability of the Alberta Infant Motor Scale (AIMS) applied by final level undergraduate physiotherapy students. Materials and methods An assessment of evaluation of diagnostic tests was done in 21 clinically healthy infants of both genders, aged 0 to 18 months, residents at Bucaramanga, Colombia. The evaluation was conducted by 12 raters, 11 physiotherapy students in final level and a physiotherapist with experience in pediatrics. The assessments were performed with an interval of one week and by video. An Intraclass Correlation Coefficient (ICC) was applied for the reliability analysis and Standard Error of Measurement (SEM) was obtained, considering an α=0.05.ResultsA very good inter-rater reliability for the total score (ICC>0.98) and the sitting subscale (ICC>0.97) were registered. The other subscales showed moderate reliability, ICC between 0.54 and 0.64. Intra-rater reliability showed low to excellent ICC. The SEM was low for the standing, prone subscales and total score (0.20 to 0.77).Conclusions The AIMS is a reliable tool that can be used in our context by undergraduate physical therapy students in their year of study in order to assess motor development in clinically healthy children (AU)

The aim of the present study was to determine in adolescents the relationship between insulin levels and body mass index (BMI), body fat distribution, diet, life style and lipid profile. We studied 167 adolescents (68 boys and 99 girls) whose ages ranged from 14 to 17 years. A detailed medical (including pubertal stage) and nutritional record was obtained from each subject. Biochemical measurements included fasting serum insulin, glucose, total cholesterol (TC), triglycerides (Tg), HDL-C, LDL-C and VLDL-C. HOMA insulin resistance (IR) and HOMA beta-cell function (beta-cell) were calculated. Insulin levels were over 84 pmol/L (cut off normal value in our lab) in 56 per cent of the boys and 43 per cent of the girls. Thirty-seven percent of lean adolescents whose BMI was 21.5 +/- 1.9 kg/m2 presented higher fasting insulin levels. HOMA IR, Tg, systolic (SBP) and diastolic blood pressure (DBP) values when compared to a lean normoinsulinemic group. Insulin levels were correlated (p < 0.01) with body mass index. Both boys and girls in the highest BMI quartile (BMI > 24 kg/m2) had significantly higher serum insulin, HOMA beta-cell, and Tg levels, and the lowest HDL-C levels. A high-energy intake rich in saturated fat and low physical activity were found in this lean but metabolically altered adolescents. We conclude that even with a BMI as low as 21 kg/m2 an inappropriate diet and low physical activity might be responsible for the high insulin levels and dislipidemias in adolescents.
