Telemedicine may support individual care plans in people with chronic obstructive pulmonary disease (COPD), potentially improving the clinical outcomes. To-date there is no clear evidence of benefit of telemedicine in this patients. The aim of this study is to provide an update on the effectiveness of telemedicine in reducing adverse clinical outcomes. We searched the Pubmed database for articles published between January 2005 and December 2014. We included only randomized controlled trials exclusively focused on patients with COPD and with a telemedicine intervention arm. Evaluated outcomes were number of exacerbations, ER visits, COPD hospitalizations, length of stay and death. We eventually included 12 randomized controlled trials. Most of them had a small sample size and was of poor quality, with a wide heterogeneity in the parameters and technologies used. Most studies reported a positive effect of telemonitoring on hospitalization for any cause, with risk reductions between 10% and 63%; however only three studies reached statistical significance. The same trend was observed for COPD-related hospital admission and ER visits. No significative effects of telemedicine was evidenced in reducing length of hospital stay, improving quality of life and reducing deaths. In conclusion, our study confirms that the available evidence on the effectiveness of telemedicine in COPD does not allow to draw definite conclusions; most evidence suggests a positive effect of telemonitoring on hospital admissions and ER visits. More trials with adequate sample size and with adequate consideration of background clinical services are needed to definitively establish its effectiveness.

Background/Objectives: there is conflicting evidence on the role of the Mediterranean Diet (MD) in reducing the risk of long-term outcomes in older adults. The aim of our study was to assess the effectiveness of high adherence to MD in reducing all-cause mortality and cardiovascular outcomes among older adults. Methods: PubMed database was searched up to 31 May 2023. We included randomized controlled trials (RCT) and cohort studies in the English language which evaluated the Mediterranean diet’s adherence to exposure on a population with a mean age > 60 years. The main outcomes were cardiovascular fatal and non-fatal events, and all-cause mortality. A sub-analysis on individuals > 70 years old was conducted. Meta-analysis of Observational Studies in Epidemiology (MOOSE) and Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines were used for assessing data quality and validity. Pooled data were obtained by using random-effects models. Results: a total of 28 studies were included in this meta-analysis (26 observational studies and 2 randomized trials), reporting a total of 679,259 participants from different continents. Our results showed that high adherence to the MD reduces all-cause mortality risk by 23% (95% CI: 0.70–0.83), while it decreases the risk of cardiovascular mortality by 27% (95% CI: 0.64–0.84) and that of non-fatal cardiovascular events by 23% (95% CI: 0.55–1.01). Conclusions: MD is a promising dietary pattern for promoting health among older adults, as it is associated with reduced risks of all-cause and cardiovascular mortality, and non-fatal cardiovascular events. Adopting a Mediterranean Diet may contribute to better overall health and a lower likelihood of cardiovascular-related health issues in older individuals.
