Assessment of the Impact of COVID-19 Lockdown on the Nutritional Status and Lipid Profile of Employees in a Teaching Hospital in Rome: A Retrospective Cohort Study.

BACKGROUND: on the 9 March 2020, the Italian government declared a state of lockdown on the entire national territory aimed at reducing the spread of SARS-CoV-2, causing strong repercussions for people's lifestyles. The aim of the study was to analyze the impact of the lockdown on the nutritional status and lipid profile of employees of an Italian teaching hospital. METHODS: an observational retrospective cohort study was carried out at the Department of Occupational Medicine of the Umberto I General Hospital of Rome, including all employees who underwent two consecutive occupational medical examinations before and after the first lockdown (9 March 2020-18 May 2020). Employee medical records were used as a data source. RESULTS: 1014 employees were involved in the study (50.6% nurses, 31% physicians, 14.8% technical staff, 3.6% administrative staff). Post lockdown BMI, total cholesterol and LDL values increased statistically significantly compared to pre lockdown ones. Nurses showed a significant association with increased BMI (p < 0.001), while workers with heart disease were inversely associated with total cholesterol (p < 0.001) and LDL (p < 0.001). CONCLUSION: this study showed that lockdown had a significant impact on employees' lifestyles. Further studies are needed to understand changes in health-related behaviors, such as diet and physical activity, of specific categories of workers over time under lockdown conditions.

Clinical efficacy of eucaloric ketogenic nutrition in the COVID-19 cytokine storm: A retrospective analysis of mortality and intensive care unit admission.

OBJECTIVES: Our primary objective was to explore the effect of a eucaloric ketogenic diet (EKD) on mortality, admission to the intensive care unit, and need for non-invasive ventilation in hospitalized patients with COronaVIrus Disease 19 (COVID-19), in comparison to a eucaloric standard diet. Secondary objectives were verification of the safety and feasibility of the diet and its effects on inflammatory parameters, particularly interleukin-6. METHODS: The study is a retrospective analysis of 34 patients fed with an EKD in comparison to 68 patients fed with a eucaloric standard diet, selected and matched using propensity scores 1:2 to avoid the confounding effect of interfering variables. Our hypothesis was that an EKD would reduce mortality, admission to the intensive care unit, and need for non-invasive ventilation in patients with COVID-19. RESULTS: The preliminary multivariate analysis showed a statistically significant difference in survival (P = 0.046) and need for the intensive care unit (P = 0.049) for the EKD compared with a eucaloric standard diet. Even considering the EKD start day as a time-dependent variable, the results maintain a positive trend for application of the diet, and it is not possible to reject the null hypothesis (P < 0.05). Interleukin-6 concentrations between t0 and t7 (7 d after the beginning of the diet) in the ketogenic nutrition group show a trend that is almost significant (P = 0.062). The EKD was safe and no adverse events were observed. CONCLUSIONS: These results show a possible therapeutic role of an EKD in the clinical management of COVID-19. Currently, a prospective controlled randomized trial is running to confirm these preliminary data.

The "Elderly" Lesson in a "Stressful" Life: Italian Holistic Approach to Increase COVID-19 Prevention and Awareness.

It's a frightening time due to COVID-19, but the great elderly/centenarians, apparently with more frailty, seem to have a better response to the pandemic. "The South Italy" lifestyle seems an "effective strategy" promoting the well-being embedded in a holistic solution: healthy diet, less exposure to PM10 pollution, protected environment, and moderate physical activity. The European FP7 Project RISTOMED results, since 2010, have shown that dietary intervention improved a heathy status in the elderly people. Based on the RISTOMED results, in addition to sociocultural and environmental factors, the authors suggest an integrated approach for resilience to COVID-19. Such an approach during the next months could make the difference for the success of any government progress policy to fight COVID-19, finalizing long-term well-being and successful aging.
