ABSTRACT
OBJECTIVES: This study aimed i) to assess the assumptions made in the sit-to-stand (STS) muscle power test [body mass accelerated during the ascending phase (90% of total body mass), leg length (50% of total body height) and concentric phase (50% of total STS time)], ii) to compare force plate-derived (FPD) STS power values with those derived from the STS muscle power test; and iii) to analyze the relationships of both measurements with physical function. MATERIAL AND METHODS: Fifty community-dwelling older adults (71.3 ± 4.4 years) participated in the present investigation. FPD STS power was calculated as the product of measured force (force platform) and velocity [difference between leg length (DXA scan) and chair height, divided by time (obtained from FPD data and video analysis)], and compared to estimated STS power using the STS muscle power test. Physical function was assessed by the timed-up-and-go (TUG) velocity, habitual gait speed (HGS) and maximal gait speed (MGS). Paired t-tests, Bland-Altman plots and regressions analyses were conducted. RESULTS: Body mass accelerated during the STS phase was 85.1 ± 3.8% (p < 0.05; compared to assumed 90%), leg length was 50.7 ± 1.3% of body height (p < 0.05; compared to 50%), and measured concentric time was 50.3 ± 4.6% of one STS repetition (p > 0.05; compared to assumed 50%). There were no significant differences between FPD and estimated STS power values (mean difference [95% CI] = 6.4 W [-68.5 to 81.6 W]; p = 0.251). Both FPD and estimated relative (i.e. normalized to body mass) STS power were significantly related to each other (r = 0.95 and ICC = 0.95; p < 0.05) and to MGS and TUG velocity after adjusting for age and sex (p < 0.05). CONCLUSIONS: Estimated STS power was not different from FPD STS power and both measures were strongly related to each other and to maximal physical performance.

La afectación del tracto gastrointestinal por citomegalovirus es una entidad que se suele dar en pacientes inmunocomprometidos, no obstante es más raro verlo en pacientes inmunocompetentes. La edad media recogida en una serie de casos es de 68 años y los síntomas acompañantes son diarrea (76%), dolor abdominal (52%) y hematoquecia o melena (27%). A continuación describimos el caso de un paciente de 85 años sin ningún estado inmunocomprometido que se identificase que desarrolló una colitis por CMV
Gastrointestinal tract involvement due to cytomegalovirus infection is a condition that usually occurs in immunocompromised patients, but is uncommon in immunocompetent patients. In a review of 33 cases, the median age was 68 years, and the accompanying symptoms were diarrhoea (76%), abdominal pain (52%), and haematochezia, or melena (27%). The case is presented of ctyomegalovirus colitis in an 85 year-old man with no previously identified immunocompromised states

El síndrome de Ekbom, también conocido como delirio de parasitosis, consiste en la creencia de estar infestado por insectos u organismos vivientes que recorren el cuerpo de quien lo padece sin que haya evidencia de ello. Las quejas suelen estar centradas en esta idea de parasitación, no obstante también se puede acompañar de ansiedad o depresión. Este trastorno puede ser sin patología médica asociada (primario) o con patología orgánica asociada (secundario). Se presenta el caso de un varón de 81 años que presenta un cuadro compatible con este síndrome, así como la respuesta al tratamiento con antipsicóticos y antidepresivos
Ekbom's syndrome, also known as delusional parasitosis, consists of the belief of being infested with insects or living organisms which crawl through the body when there is no evidence of such infestation. Complaints are usually focused on this idea of parasitization; however it can also be accompanied by anxiety or depression. This condition can be primary (with no associated disorders) or secondary (with associated organic diseases). We present the case of an 81 year-old man with this syndrome, and his response to treatment with antipsychotics and antidepressants
