Does physical exercise improve ADL capacities in people over 65 years with moderate or severe dementia hospitalized in an acute psychiatric setting? A multisite randomized clinical trial.
Several studies on the effect of physical exercise on activities of daily living (ADL) for people with dementia exist; yet, data concerning the specific context of acute psychiatric hospitals remain scant. This study measured the effect of a physical exercise program on ADL scores in patients with moderate to severe dementia hospitalized in an acute psychiatric ward.
A multicenter clinical trial was conducted in five Swiss and Belgian psychiatric hospitals. Participants were randomly allocated to either an experimental group (EG) or a control group (CG). Members of the EG received 20 physical exercise sessions (strengthening, balance, and walking) over a four-week period while members of the CG participated in social interaction sessions of equivalent duration and frequency, but without physical exercise. The effect of exercise on ADL was measured by comparing scores of the Barthel Index and the Functional Independence Measure in the EG and CG before and after the intervention, and two weeks later.
Hundred and sixty patients completed the program. Characteristics of participants of both groups were similar at the inception of the study. The mean ADL score of EG decreased slightly over time, whereas that of the CG significantly decreased compared to initial scores. Overall differences between groups were not significant; however, significant differences were found for mobility-related items.
ADL scores in elderly with moderate to severe dementia deteriorate during acute psychiatric hospitalization. An exercise program delays the loss of mobility but does not have a significant impact on overall ADL scores
p53 as a potential predictive factor of response to chemotherapy: feasibility of p53 assessment using a functional test in yeast from trucut biopsies in breast cancer patients
Assessment of the predictive value of p53 requires the testing of large numbers of samples from patients enrolled in prospective phase III clinical trials. The goal of this study was to determine whether p53 status can be determined by p53 yeast functional assay using the limiting amounts of material that can typically be obtained in prospective phase III trials (particularly when chemotherapy is given before surgery). All patients presenting with a clinically palpable tumour which could be considered large enough to perform a trucut biopsy (⩾2 cm breast tumour) were eligible for this study. Two trucut biopsies and one incisional biopsy were performed on the surgical specimens (mastectomy or tumourectomy). Samples were snap frozen and cryostat sections were taken for histology and p53 testing. Thirty patients were included. Three samples out of 90 failed to give any p53 PCR products, probably because these samples contained almost entirely fibrous tissue. Of the 87 samples that could be tested, the incisional and trucut biopsies results were fully concordant in every case. p53 could be defined in 97% of patients by double trucut biopsy. Eight out of 30 tumours tested were mutant for p53 (27%). p53 status can be reliably determined by yeast assay from single frozen sections of trucut biopsies. Histological examination before p53 testing is essential to exclude cases where the p53 result may reflect only the status of the normal cells in the biopsy
Facilitators and barriers in implementing clinical nursing assessment in mental health care for older people: A multimethod approach.
With the aging of the population and the growing prevalence of dementia, specialized and collaborative nursing care is paramount in this area. To ensure better quality care, it is necessary to use effective and context-specific processes to implement evidence-based practices and more specifically clinical nursing assessment. This study aimed to identify and describe factors that may influence the implementation of clinical nursing assessment in mental health care for older people. The Consolidated Framework for Implementation Research was employed to guide evaluation in the pre-implementation phase in the specific context of mental health care for older people. Using a multimethod approach, interviews, focus groups, and a quantitative survey were conducted with a non-probability convenience sample. A total of 39 hospital nurses (registered nurses and head nurses) were interviewed. Analysis yielded five main factors, notably three barriers and two facilitators. Barriers include a lack of general nursing culture, deficiencies in leadership, and difficulties in communication and collaboration. Facilitators comprise team cohesion and the perceived benefits of the study
