ABSTRACT
AIMS: The aim of the study was to investigate the association between type-2 diabetes mellitus, other underlying diseases and obesity with the outcomes of critically ill Covid-19 patients in Greece. METHODS: In this retrospective observational multi-centre study, data and outcomes of 90 RNA 2109-nCoV confirmed critically ill patients from 8 hospitals throughout Greece, were analysed. All reported information stand through April 13th 2020. RESULTS: The median age of the patients was 65.5 (IQR 56-73), majority were male (80%) and obesity was present in 34.4% of patients most prevalent to younger than 55 years. Hypertension was the prevailing comorbidity (50%), followed by cardiovascular diseases (21.1%) and type-2 diabetes (18.9%). At admission, common symptoms duration had a median of 8 (IQR 5-11) days. A 13.3% of the patients were discharged, 53.4% were still in the ICUs and 28.9% deceased who were hospitalised for fewer days than the survivors [6 (IQR 3-9) vs. 9 (IQR 7-14.5) respectively]. Aging was not a risk factor but diabetes deteriorates the outcomes. Obesity poses a suggestive burden as it was more notable in deceased versus survivors. CONCLUSIONS: Type 2 diabetes and obesity may have contributed to disease severity and mortality in COVID-19 critically ill patients in Greece.

INTRODUCTION: Cystic fibrosis (CF) is the most common life-limiting, recessively inherited disease in the white population, associated with significantly high morbidity and mortality rates; CF pulmonary disease, assessed by pulmonary function tests, arterial blood gases and the Schwachman score, remains the most prevalent in terms of morbidity in the adult CF population. OBJECTIVES: The aim of the present study was to evaluate the relationship between resting respiratory variables and exercise capacity in adult patients with CF. RESULTS: Study investigations undertaken in 18 CF patients and 11 healthy volunteers showed that among the resting lung function parameters, inspiratory capacity (IC) at rest was the only significant predictor of VO(2) peak (r=0.67, p<0.007) and VO(2)/t-slope (r=0.86, p<0.0001). The percentage of predicted FEV(1) in adult CF patients was 77+/-33% pred. vs 104+/-16% pred. in healthy subjects (p<0.006); the corresponding percentage of IC at rest was 82+/-36% pred. in patients vs 116+/-20% pred. in healthy (p<0.003). CF patients presented with a significantly prolonged rapid breathing after exercise (32br per minute at recovery for CF vs 22 for healthy; p<0.001), as well as a shortened inspiratory time. CONCLUSION: Adult patients with CF show a limited exercise capacity with lower peak oxygen consumption and prolonged oxygen kinetics. Interestingly, decreased IC qualified as the only significant predictor of exercise capacity in our study.
