Risks associated with intensive blood pressure control in older patients.

Hypertension management forms a cornerstone of cardiovascular prevention. Strong evidence is available supporting the benefits of blood pressure (BP) lowering in older adults, and recent studies indicate that intensive BP control may provide additional advantages concerning cardiovascular and mortality risk, also at older ages. Yet, in older adults, the cardiovascular benefit of intensive treatment may come at the expense of an increase in adverse events. Indeed, advanced age and frailty may modify the risk/benefit ratio of BP lowering due to a greater predisposition to hypotension and more severe consequences deriving from treatment-related adverse effects. This mostly applies to individuals with poor health status and limited life expectancy, in whom aggressive BP lowering may not lead to cardiovascular benefits but rather increase the risk of short-term treatment-related complications. Furthermore, potential harms of intensive BP control might be underestimated in clinical trials due to exclusion criteria that preclude patients with frailty and multimorbidity from being eligible. Syncope and falls are the most frequently mentioned safety concerns related to antihypertensive treatment, but aggressive BP lowering may affect negatively also renal function, cognitive performance, quality of life, and survival. With the growing emphasis on intensive treatment strategies, raising the awareness of potential harms associated with aggressive BP lowering might help improve hypertension management in older adults and encourage implementation of clinical research on safety. Given these premises, we present a narrative review illustrating the most relevant risks associated with intensive BP control in older patients.

Absence of negativization of nasal swab test and frailty as risk factors for mortality in elderly COVID-19 patients admitted in long-term care facilities.

METHODS: A limited amount of data is now available on prognostic factors and mortality among elderly people resident in Long-Term Care facilities and in post-acute units. These populations (in particular those with underlying chronic medical conditions) seem to have higher risk of morbidity and mortality related to COVID-19 disease, but further evidence is needed. The aim of our study is to investigate the impact of some well-known prognostic factors in elderly patients (≥ 65 years) with COVID-19 admitted in the Long-Term Care setting in AUSL Ferrara, Italy. We performed binary regression logistic analysis for some variables (demographic data, clinical data including nasal swab test (NST) at discharge and frailty assessments) to find potential predictors of mortality. We subsequently tested statistically significant variables using Kaplan-Meier curves and Cox-regression models to find survival outcomes and related hazard ratio. RESULTS: Risk factors associated with increased mortality resulted NST at discharge, infection, age and frailty. At a further secondary analysis carried out between NST at discharge, age and clinical frailty scale (CFS) < 5, we found a positive correlation between NST at discharge and CFS < 5. Kaplan-Meier curves showed a statistically significant difference regarding frailty and NST at discharge but not for age. CONCLUSION: Our study showed that absence of negativization of NST at discharge and frailty are strong predictors for mortality in elderly COVID-19 patients admitted in Long-Term Care facilities, while age and the comorbidity burden are less important.

Samples and data accessibility in research biobanks: an explorative survey.

Biobanks, which contain human biological samples and/or data, provide a crucial contribution to the progress of biomedical research. However, the effective and efficient use of biobank resources depends on their accessibility. In fact, making bio-resources promptly accessible to everybody may increase the benefits for society. Furthermore, optimizing their use and ensuring their quality will promote scientific creativity and, in general, contribute to the progress of bio-medical research. Although this has become a rather common belief, several laboratories are still secretive and continue to withhold samples and data. In this study, we conducted a questionnaire-based survey in order to investigate sample and data accessibility in research biobanks operating all over the world. The survey involved a total of 46 biobanks. Most of them gave permission to access their samples (95.7%) and data (85.4%), but free and unconditioned accessibility seemed not to be common practice. The analysis of the guidelines regarding the accessibility to resources of the biobanks that responded to the survey highlights three issues: (i) the request for applicants to explain what they would like to do with the resources requested; (ii) the role of funding, public or private, in the establishment of fruitful collaborations between biobanks and research labs; (iii) the request of co-authorship in order to give access to their data. These results suggest that economic and academic aspects are involved in determining the extent of sample and data sharing stored in biobanks. As a second step of this study, we investigated the reasons behind the high diversity of requirements to access biobank resources. The analysis of informative answers suggested that the different modalities of resource accessibility seem to be largely influenced by both social context and legislation of the countries where the biobanks operate.
