COVID-19 and cardiovascular problems in elderly patients: Food for thought.

The global number of COVID-19 infections, as of December 23, 2020, stood at approximately 79 million, with over 1.7 million deaths. The development of vascular inflammation may also contribute to a hypercoagulable state and endothelial dysfunction in such patients. It is known that multi-organ damage is more likely in patients with sepsis if they develop coagulopathy and that inhibition of thrombin synthesis can have a positive impact in reducing mortality. In this review, we will focus on the protection of the most fragile groups of the population, such as the elderly. This segment of the population will be a key issue and probably of primary interest to all. Biomarkers appear to be extremely useful as an indicator of what is happening from a pathophysiological point of view in the heart, allowing us to better stratify the prognosis of our patients affected by COVID-19, especially in the most severe cases and those with comorbidities.

Glucose metabolism in the idiopathic blepharoptosis: utility of the Oral Glucose Tolerance Test (OGTT) and of the Insulin Resistance Index.

BACKGROUND: Diabetes mellitus (DM), neuromuscular, hereditary or immunological disorders are the most common identified causes of blepharoptosis. However, in about 15-25% they remained uncertain. OBJECTIVE: To determined the role of glucose metabolism abnormality in idiopathic blepharoptosis. METHODS: We identified 162 patients with unilateral idiopathic blepharoptosis and 128 control subjects. In all we evaluated a glucose and insulin levels at fasting and after 2 h-OGTT. In addition we determined insulin resistance (IR), by HOMA-index. RESULTS: Following a 2 h-OGTT the prevalence of undiagnosed glucose metabolism abnormality was significantly higher in blepharoptosis patients vs. control group (P<.001). The IR was documented in 129 patients (78%), of whom 55 (34%) had Impaired Glucose Tolerance (IGT), 36 (22%) newly diagnosed DM (NDDM) and 38 (30%) only IR. The Body Mass Index, blood pressure, serum lipids, triglycerides and smoking were not associated with an increased risk of developing ptosis. Conversely, waist circumference were significantly increased in blepharoptosis patients (P=.003). CONCLUSIONS: In this study we focused on emerging evidence that prediabetic status may represent a risk factor for developing blepharoptosis. We propose that 2 h-OGTT and mainly HOMA-index should be determined as a rule in all patients with idiopathic blepharoptosis.
