ABSTRACT Background Nutritional status and daily physical activity (PA) may be an excellent tool for the maintenance of bone health in patients with cystic fibrosis (CF). Objective To evaluate the relationship between nutritional status, daily physical activity and bone turnover in cystic fibrosis patients. Method A cross-sectional study of adolescent and adult patients diagnosed with clinically stable cystic fibrosis was conducted. Total body, femoral neck, and lumbar spine bone mineral density (BMD) were determined by dual energy X-ray absorptiometry and bone metabolism markers ALP, P1NP, PICP, and ß-CrossLaps. PA monitoring was assessed for 5 consecutive days using a portable device. Exercise capacity was also determined. Serum 25-hydroxyvitamin D and vitamin K were also determined in all participants. Results Fifty patients (median age: 24.4 years; range: 16-46) were included. BMI had positive correlation with all BMD parameters, with Spearman’s coefficients ranging from 0.31 to 0.47. Total hip bone mineral density and femoral neck BMD had positive correlation with the daily time spent on moderate PA (>4.8 metabolic equivalent-minutes/day; r=0.74, p<0.001 and r=0.72 p<0.001 respectively), daily time spent on vigorous PA (>7.2 metabolic equivalent-minutes/day; r=0.45 p<0.001), body mass index (r=0.44, p=0.001), and muscle mass in limbs (r=0.41, p=0.004). Levels of carboxy-terminal propeptide of type 1 collagen were positively associated with the daily time spent on moderate (r=0.33 p=0.023) and vigorous PA (r=0.53, p<0.001). Conclusions BMI and the daily time spent on moderate PA were found to be correlated with femoral neck BMD in CF patients. The association between daily PA and biochemical markers of bone formation suggests that the level of daily PA may be linked to bone health in this patient group. Further research is needed to confirm these findings.

Objective: To know the prescription of generic drugs in specialized attention and the impact of two different intervention strategies: Material and methods: Intervention trial with evaluation and later comparison. The data on the use of generic drugs are obtained from the medical reports. After an informative note of general character we repeated the taking of data one month later. In the service of Medicine we also analysed each doctor's profile prescriptions and a personalized informative note was edited and accompanied by a brief verbal explication of the campaign. Then repeated the collection of data to the week and the month. Results: 1545 reports were revised (3460 prescribed drugs). 42% of the medication could be prescribed as generic but it was only made in 10% (21% in Internal Medicine). After the informative note no significant variations were observed. Only in Internal Medicine an initial increment was obtained (21% to 56%, RR 0,38, IC 0.26-0.55) that it disappeared at month. Comments: The utility of the intervention to generic promotion is limited and transitory. Besides improve the information, semms necessary the implication of the physician in the promotion campaigns.

Objetivo: Conocer los hábitos de prescripción de especialidades farmacéuticas genéricas en atención hospitalizada y el impacto de dos diferentes estrategias de intervención. Material y métodos: Se diseña un estudio de intervención con evaluación previa y comparación posterior. A partir de los informes de alta generados en el Hospital Comarcal Francisco de Borja de Gandía se recogieron los fármacos prescritos, la proporción de ellos en los que existe alternativa como EFG disponible y porcentaje que se pauto como tal. Tras una notar informativa de carácter general se repitió la toma de datos al mes. En el Servicio de Medicina Interna se analizó también el perfil presciptor de cada facultativo, redactándose una hoja informativa personalizada que se distribuyo de forma personal, acompañada de una breve explicación verbal. Se repitió la toma de datos a la semana y al mes. Resultados: Se revisaron un total de 1545 informes de alta y 3460 fármacos prescritos. En la toma de datos basal el 42% de la medicación prescrita podría haberse pautado como EFG pero se prescribió como tal en el 10 % (21% en el Servicio de Medicina Interna). Tras la nota informativa general no se objetivaron variaciones significativas en el porcentaje de utilización de EFG. En Medicina Interna, se obtuvo un significativo incremento a la semana de la intervención, del 21% se paso al l 56,8% (RR 0.38 IC al 95% (0,26- 0,55) pero que tendía a desvanecerse al mes (27%) perdiendo significación estadística. Comentarios: La utilidad de campañas de promoción del uso de EFG es limitada y transitoria por lo que además de mejorar la información respecto a la disponibilidad y eficacia de las EFG, se debería contemplar la implicación del prescriptor tanto en la atención primaria como en la especializada.
