Introduction Hospitalization is associated with acute changes in sarcopenia status in older people, but the influencing factors are not fully understood. Pre-admission care dependency level as a risk factor has not yet been investigated. Objective Evaluate if pre-admission care dependency level is an independent predictor of sarcopenia changes following hospitalization. Setting and subjects Data came from the Sarcopenia 9+ EAMA Project, a European prospective multi-centre study. For this study, 227 hospitalised older people were included from four different hospitals in Belgium, Spain and Poland, between 18 February 2019 and 5 September 2020. Methods Sarcopenia status at admission and discharge were calculated using a combined score (desirability value) based on muscle mass (calf circumference), strength (grip) and function (walking speed). Ratio of admission to discharge status was the outcome (desirability ratio; 1.00 meaning no difference). Predictor variable was the pre-admission care dependency level, classified into three groups: independent older people living at home, dependent older people living at home and older people living in a care home. Linear regression models were applied, considering potential confounders. Results Mean desirability ratio for dependent older people living at home ('middle dependent group') was lower (0.89) compared to independent older people (0.98; regression coefficient −0.09 [95% CI −0.16, −0.02]) and care home patients (1.05; −0.16 [95% CI −0.01, −0.31]). Adjusting for potential confounders or using another statistical approach did not affect the main results. Conclusion Dependent older people living at home were at higher risk of deterioration in sarcopenia status following hospitalization. In-depth studies investigating causes and potential interventions of these findings are needed. [ABSTRACT FROM AUTHOR]

We wanted to explore possible differences in disease presentation, frequency, and age of onset of dementia with Lewy bodies (DLB) between first-generation immigrants (FGI) and patients born in Belgium (PBIB). We conducted a retrospective study on all patients of our Memory Clinic between June 1, 2010 and January 31, 2020. A synucleinopathy was diagnosed in 150 of 2702 patients (5.5%): 91 received a diagnosis of DLB (3.4%). FGI were two times more likely to receive a diagnosis of DLB, due to a higher prevalence in North-Africans and Latin-Americans. Visual hallucinations were less frequent in North-Africans than in other immigrants. FGI were younger than PBIB and reported more often parasomnia. Our data suggest a higher risk for DLB in certain immigrant groups. Especially for North-African patients, a genetic factor can be suspected, namely mutations in Leucine-rich repeat kinase 2 (LRRK2). Memory clinics with a high rate of FGI may provide interesting data and insights into the prevalence of DLB, genetic and environmental differences.

Objective: This retrospective study aimed to evaluate the incidence of transdermal rivastigmine treatment withdrawal secondary to adverse skin reactions among the patients from our Memory Clinic. In addition, we tested whether climatic conditions might have an influence on skin irritations leading to eventual treatment disruption., Methods: We performed a retrospective review of patients from the Brugmann University Hospital Memory Clinic having started transdermal rivastigmine between June 2008 and December 2010. Local meteorological data were provided by the Royal Meteorological Institute of Belgium., Results: A total of 26.9% of the patients experienced adverse skin reactions at the rivastigmine application site, leading to treatment discontinuation in 19.2% of the cases. Rivastigmine cutaneous tolerability was not found to be related to demographic parameters, Mini Mental Status Examination score, or type of dementia. High temperature and low air humidity during the first month of treatment were found to be associated with a higher incidence of skin reactions and secondary treatment disruption., Conclusions: Transdermal rivastigmine induced a higher incidence of cutaneous adverse events than previously reported in a prospective clinical trial. Moreover, it seems that meteorological conditions favoring skin perspiration (high temperature and low air humidity) during the first month of treatment might have an influence on transdermal rivastigmine skin tolerability.
