Impact of the Mediterranean Diet on the Gut Microbiome of a Well-Defined Cohort of Healthy Individuals.

A comprehensive understanding of gut microbiota in a clearly defined group of healthy individuals is essential when making meaningful comparisons with various diseases. The Mediterranean diet (MD), renowned for its potential health benefits, and the influence of adherence thereto on gut microbiota have become a focus of research. Our aim was to elucidate the impact of adherence to the MD on gut microbiota composition in a well-defined cohort. In this prospective study, healthy volunteers completed a questionnaire to provide demographic data, medical history, and dietary intake. Adherence was evaluated using the Med-DQI. The V4 region of the 16S rRNA gene was sequenced. Analysis of sequencing data and statistical analysis were performed using MOTHUR software and R. The study included 60 patients (51.7% females). Adherence correlated with alpha diversity, and higher values were recorded in good adherers. Good adherers had a higher abundance of Paraprevotella and Bacteroides (p < 0.001). Alpha diversity correlated inversely with fat intake and positively with non-starch polysaccharides (NSPs). Evenness correlated inversely with red meat intake and positively with NSPs. Predicted functional analysis highlighted metabolic pathway differences based on adherence to the MD. In conclusion, our study adds useful information on the relationship between the MD and the gut microbiome.

Resilience After COVID-19: A Descriptive, Cross-Sectional Study.

The main purpose of this study was to examine the relationship between resilience and health-related quality of life in patients following COVID-19 disease among those with and without lingering symptoms. The study design is descriptive and cross-sectional. Participants (n = 97) were adults who had earlier contracted COVID-19 disease and were in post-infection status between July and October 2020. Participants completed the following instruments: Connor-Davidson Resilience Scale, Short-Form 12-item Health Survey, and Hospital Anxiety and Depression Scale. Approximately 35% post-COVID-19 patients had a low level of resilience. The impact on the health status and resilience of those who had reported symptoms after 6 months was also significant. Age and depression had a significant impact on level of resilience. This relationship can affect patient recovery and negatively impact the ability to cope with COVID-19 disease. It is necessary to implement specialized training for clinicians on the effects of long-term COVID-19 to improve patient care. Long COVID symptoms might manifest months after an acute COVID-19 illness; clinicians who can confirm patient reports of these symptoms may help patients recover and become more resilient.
