Effectiveness of individually tailored exercise on functional capacity and mobility in nursing home residents.

Deterioration of physical and functional capacities is often seen in nursing homes. The present study aimed at assessing the effectiveness of an individually tailored physical exercise intervention on mobility and functional decline in nursing home residents in a 1-year follow-up period. Information on gender, age, education, profession and cognitive status was collected at baseline and at 6 and 12 months of the intervention. The decline in functional capacity and mobility was assessed using the Barthel index. Some 221 participants were included. Results from the multivariate logistic regression showed how residents who never participated in physical activities had a five-fold higher risk of mobility decline compared with residents who did engage for the whole follow-up time. A lower effect was seen in residents who participated for only 6 months. Although dementia appeared to be a significant predictor of decline, a substantial stabilisation in mobility capacity was noted in patients with both mild and severe dementia performing exercise. The findings suggest that preventing or slowing physical decline in nursing home residents is an achievable goal, and even those with a higher degree of cognitive decline may benefit from a tailored physical activity plan.

Increase in Frailty in Nursing Home Survivors of Coronavirus Disease 2019: Comparison With Noninfected Residents.

OBJECTIVES: Institutionalized older adults have a high prevalence of frailty and disability, which may make them more vulnerable to the negative consequences of coronavirus disease 2019 (COVID-19). We investigated the impact of COVID-19 on the level of frailty, physical, and cognitive performance in nursing home residents. DESIGN: Nested case-control study. SETTING AND PARTICIPANTS: The study included nursing home residents who were infected with COVID-19 (case group, n = 76), matched by age to a control group (n = 76). METHODS: Participants' sociodemographic and medical data were collected, and they were also assessed for physical function (handgrip and walking speed), cognitive performance (Mini-Mental State Examination) and frailty (Frail-NH scale) before the first wave of the COVID-19 pandemic (October to December 2019, pre-COVID-19) and after (June to July 2020, post-COVID-19). COVID-19 symptoms and clinical course were recorded for the cases. RESULTS: Between the pre- and post-COVID-19 assessments, we found a 19% greater deterioration in handgrip, a 22% greater decrease in walking speed, and a 21% greater increase in Frail-NH scores in cases compared with controls. In both cases and controls, on the other hand, there was a significant 10% decrease in Mini-Mental State Examination scores over the study period. Multivariable logistic regression showed that COVID-19 survivors had a 4-fold increased chance of developing frailty compared with controls (odds ratio 4.95, 95% confidence interval 1.13-21.6, P = .03), but not cognitive decline. CONCLUSIONS AND IMPLICATIONS: COVID-19 can accelerate the aging process of institutionalized older adults in terms of physical performance and frailty by around 20%. However, we found similar levels of decline in cognitive performance in both cases and controls, likely because of the burden of social isolation and containment measures on neuropsychological health.

Anti-prothrombin antibodies as a potential risk factor of recurrent venous thromboembolism.

The role of antiprothrombin (aPT) antibodies in the development of venous thromboembolism (VTE) is still uncertain. The aim of this study was to evaluate the potential role of aPT antibodies in the development of recurrent thromboembolism. Out of 236 consecutive symptomatic patients with an episode of acute VTE, antiphospholipid antibodies were found in 85 (36.0%), of whom 24 were carriers of aPT antibodies (10.2% of the entire cohort). A history of previous thromboembolism was identified in 56 patients (23.7%). The prevalence of previous thromboembolism was significantly higher in carriers than in non-carriers of antiphospholipid antibodies (OR=2.4; 95% CI, 1.3 to 4.4). Of the 24 patients with aPT antibodies, 12 had a history of previous thromboembolism. In a multivariate logistic regression analysis, in which the other categories of antiphospholipid antibodies were taken into account, as well as the patient's age, sex, and the modality of clinical presentation, it was found that the presence of aPT antibodies was significantly associated with the prevalence of prior thromboembolism (OR=3.3; 95% CI, 1.3 to 8.6). Since aPT antibodies are more commonly identifiable in patients with multiple thrombotic episodes, they are a likely risk factor for recurrent thromboembolism.

Angiotomografía de las variantes anatómicas de la arteria cística: estudio en el preoperatorio de colelitiasis / Angiotomography of the anatomical variants of the cystic artery: pre-operative study of cholelithiasis

La colecistectomía laparoscópica es el tratamiento indicado en la colelitiasis, sin embargo el procedimiento no está exento de complicaciones o morbilidad concomitante. Es posible que, debido a lesiones ductales colaterales, ocurra sangrado con posibilidad de conversión de la cirugía e indeseables resultados. Para un correcto abordaje de la región se hace fundamental la identificación del trígono cistohepático (TCH) y sus componentes, a su vez de la ligadura y sección de la arteria cística (AC). Conociendo la elevada variabilidad de la AC, el objetivo de este trabajo consistió en identificar el número, origen, trayecto y relación de la AC con el TCH y sus variaciones, utilizando angiotomografía por medio de un tomógrafo detector de 64 cortes, en el preoperatorio de 30 pacientes de sexo femenino, entre 24 y 54 años de edad, con colelitiasis diagnosticadas clínicamente y por ecosonografía. La AC en el 76,67 % era única y se encontraba dentro del TCH, en el 16,67 % era única y se observó fuera del TCH. En el 6,67 % se observaron dos AC, una dentro y otra fuera del TCH. En el 66,67 % de los casos la AC se originaba de manera normal de la arteria hepática derecha. La trazabilidad de la AC fue en el 53,3 % medianamente visible y en el 46,7 % de trazabilidad excelente. En conclusión, la identificación de la AC y sus variaciones anatómicas se puede determinar en el preoperatorio y puede ser útil para mejorar el plan quirúrgico en pacientes con colelitiasis, brindando información al procedimiento, optimizarlo y disminuir los riesgos de eventuales complicaciones relacionados con sangrado.

Laparoscopic cholecystectomy is the treatment indicated for cholelithiasis, however the procedure is not free of complications or concomitant morbidity. It is possible that, due to collateral ductal lesions, bleeding occurs with the possibility of surgery conversion and undesirable results. For a correct approach to the region it is essential to identify the cystohepatic trigone (CHT) and its components, as well as the ligation and section of the cystic artery (AC). Knowing the high variability of CA, the aim of this work was to identify the number, origin, path and relationship of CA with the CHT and its variations using angiotomography by means of a 64-slice detector tomograph in the preoperative period of 30 female patients, between 24 and 54 years old, with clinically diagnosed cholelithiasis and by echo sonography. The AC in 76.67 % was unique and was within the CHT, in 16.67 % it was unique and was observed outside the CHT. In 6.67 %, two ACs were observed, one inside and one outside the TCH. In 66.67 % of cases, CA originated normally from the right hepatic artery. The traceability of AC was 53.3 % moderately visible and 46.7 % excellent traceability. In conclusion, the identification of AC and its anatomical variations can be determined in the preoperative period and can be useful to improve the surgical plan in patients with cholelithiasis, providing information on the procedure, optimizing it and reducing the risks of possible bleeding related complications.

The incidence of heparin-induced thrombocytopenia in hospitalized medical patients treated with subcutaneous unfractionated heparin: a prospective cohort study.

Although heparin-induced thrombocytopenia (HIT) is a known complication of intravenous unfractionated heparin (UFH), its incidence in medical patients treated with subcutaneous UFH is less well defined. To determine the incidence of HIT in this category of patients, the platelet count was performed at baseline and then every 3 +/- 1 days in 598 consecutive patients admitted to 2 medical wards and treated with subcutaneous UFH for prophylactic (n = 360) or therapeutic (n = 238) indications. The diagnosis of HIT was accepted in the case of a platelet drop of 50% or more and either the demonstration of heparin-dependent antibodies or (when this search could not be performed) the combination of the following features: (1) the absence of any other obvious clinical explanation for thrombocytopenia, (2) the occurrence of thrombocytopenia at least 5 days after heparin start, and (3) either the normalization of the platelet count within 10 days after heparin discontinuation or the earlier patient's death due to an unexpected thromboembolic complication. HIT developed in 5 patients (0.8%; 95% CI, 0.1%-1.6%); all of them belonged to the subgroup of patients who received heparin for prophylactic indications. The prevalence of thromboembolic complications in patients with HIT (60%) was remarkably higher than that observed in the remaining 593 patients (3.5%), leading to an odds ratio of 40.8 (95% CI, 5.2-162.8). Although the frequency of HIT in hospitalized medical patients treated with subcutaneous heparin is lower than that observed in other clinical settings, this complication is associated with a similarly high rate of thromboembolic events.
