Prognostic significance of diabetes and stress hyperglycemia in acute stroke patients.

BACKGROUND: Hyperglycemic non-diabetic stroke patients have a worse prognosis than both normoglycemic and diabetic patients. Aim of this study was to assess whether hyperglycemia is an aggravating factor or just an epiphenomenon of most severe strokes. METHODS: In this retrospective study, 1219 ischemic or hemorrhagic stroke patients (73.7 ± 13.1 years) were divided into 4 groups: 0 = non-hyperglycemic non-diabetic, 1 = hyperglycemic non-diabetic, 2 = non-hyperglycemic diabetic and 3 = hyperglycemic diabetic. Hyperglycemia was defined as fasting blood glucose ≥ 126 mg/dl (≥ 7 mmol/l) measured the morning after admission, while the diagnosis of diabetes was based on a history of diabetes mellitus or on a glycated hemoglobin ≥ 6.5% (≥ 48 mmol/mol), independently of blood glucose levels. All diabetic patients, except 3, had Type 2 diabetes. The 4 groups were compared according to clinical history, stroke severity indicators, acute phase markers and main short term stroke outcomes (modified Rankin scale ≥ 3, death, cerebral edema, hemorrhagic transformation of ischemic lesions, fever, oxygen administration, pneumonia, sepsis, urinary infection and heart failure). RESULTS: Group 1 patients had more severe strokes, with larger cerebral lesions and higher inflammatory markers, compared to the other groups. They also had a high prevalence of atrial fibrillation, prediabetes, previous stroke and previous arterial revascularizations. In this group, the highest frequencies of cerebral edema, hemorrhagic transformation, pneumonia and oxygen administration were obtained. The prevalence of dependency at discharge and in-hospital mortality were equally high in Group 1 and Group 3. However, in multivariate analyses including stroke severity, cerebral lesion diameter, leukocytes and C-reactive protein, Group 1 was only independently associated with hemorrhagic transformation (OR 2.01, 95% CI 0.99-4.07), while Group 3 was independently associated with mortality (OR 2.19, 95% CI 1.32-3.64) and disability (OR 1.70, 95% CI 1.01-2.88). CONCLUSIONS: Hyperglycemic non-diabetic stroke patients had a worse prognosis than non-hyperglycemic or diabetic patients, but this group was not independently associated with mortality or disability when size, severity and inflammatory component of the stroke were accounted for.

Clinical Role of Lung Ultrasound for the Diagnosis and Prognosis of Coronavirus Disease Pneumonia in Elderly Patients: A Pivotal Study.

BACKGROUND: Lung ultrasound (LUS) showed a promising role in the diagnosis and monitoring of patients hospitalized for novel coronavirus disease (COVID-19). However, no data are available on its role in elderly patients. AIMS: The aim of this study was to evaluate the diagnostic and prognostic role of LUS in elderly patients hospitalized for severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) pneumonia. METHODS: Consecutive elderly patients (age >65 years) hospitalized for COVID-19 were enrolled. Demographics, laboratory, comorbidity, and the clinical features of the patients were collected. All patients underwent LUS on admission to the ward. LUS characteristics have been analyzed. Uni- and multivariate analyses to evaluate predictors for in-hospital death were performed. RESULTS: Thirty-seven hospitalized elderly patients (19 men) with a diagnosis of SARS-CoV-2 infection were consecutively enrolled. The median age was 82 years (interquartile range 74.5-93.5). Ultrasound alterations were found in all patients enrolled; inhomogeneous interstitial syndrome with spared areas (91.9%) and pleural alterations (100%) were the most frequent findings. At univariate analysis, LUS score (hazard ratio [HR] 1.168, 95% CI 1.049-1.301) and pleural effusions (HR 3.995, 95% CI 1.056-15.110) were associated with in-hospital death. At multivariate analysis, only LUS score (HR 1.168, 95% CI 1.049-1.301) was independelty associated with in-hospital death. The LUS score's best cutoff for distinguishing patients experiencing in-hospital death was 17 (at multivariate analysis LUS score ≥17, HR 4.827, 95% CI 1.452-16.040). In-hospital death was significantly different according to the LUS score cutoff of 17 (p = 0.0046). CONCLUSION: LUS could play a role in the diagnosis and prognosis in elderly patients hospitalized for SARS-CoV-2 infection.

Prognostic role of nutritional status in elderly patients hospitalized for COVID-19: a monocentric study.

BACKGROUND: Symptomatic severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) infection incidence is higher in the elderly patients. Pre-existing geriatric conditions such as comorbidity and frailty seem related to worse hospital outcomes. AIMS: To assess the role of nutritional status as an independent prognostic factor for in-hospital death in elderly patients. METHODS: Consecutive elderly patients (age > 65 years) hospitalized for novel coronavirus disease (COVID-19) were enrolled. Demographics, laboratory and comorbidity data were collected. Nutritional status was evaluated using the Geriatric Nutritional Risk Index (GNRI). Uni- and multivariate Cox regression analyses to evaluate predictors for in-hospital death were performed. RESULTS: One hundred and nine hospitalized elderly patients (54 male) were consecutively enrolled. At univariate analysis, age (HR 1.045 [CI 1.008-1.082]), cognitive impairment (HR 1.949 [CI 1.045-3.364]), C-reactive protein (HR 1.004 [CI 1.011-1.078]), lactate dehydrogenases (HR 1.003 [CI 1.001-1.004]) and GNRI moderate-severe risk category (HR 8.571 [CI 1.096-67.031]) were risk factors for in-hospital death, while albumin (HR 0.809 [CI 0.822-0.964]), PaO2/FiO2 ratio (HR 0.996 [CI 0.993-0.999]) and body mass index (HR 0.875 [CI 0.782-0.979]) were protective factors. Kaplan-Meier survival curves showed a significative higher survival in patients without GNRI moderate or severe risk category (p = 0.0013). At multivariate analysis, PaO2/FiO2 ratio (HR 0.993 [CI 0.987-0.999], p = 0.046) and GNRI moderate-severe risk category (HR 9.285 [1.183-72.879], p = 0.034) were independently associated with in-hospital death. CONCLUSION: Nutritional status assessed by GNRI is a significative predictor of survival in elderly patients hospitalized for COVID-19. The association between GNRI and PaO2/FiO2 ratio is a good prognostic model these patients.

Prognostic value of non-alcoholic fatty liver disease in the elderly patients.

BACKGROUND: Non-alcoholic fatty liver disease (NAFLD) is the liver manifestation of metabolic syndrome, a risk factor for mortality and cardiovascular morbidity, but we ignore the role of steatosis per se in survival, and there is very little information about this condition in the geriatric patient. AIMS: With the present study, we investigated the independent prognostic value of NAFLD on overall mortality in the elderly. METHODS: Within the Pianoro Project, involving people ≥ 65 years, anamnestic, clinical and laboratoristic data related to NAFLD, insulin resistance, diabetes/hyperglycemia, hypertension, obesity and dyslipidemia were collected in 804 subjects (403 male, 401 female). These subjects were followed up for mortality for a median time of 12.6 years. A multivariate analysis was performed to evaluate the prognostic value of the covariates. RESULTS: At Kaplan-Meier estimator the presence of NAFLD seems to be associated to a lower mortality, and survival tends to increase with the increasing of steatosis grade. Cox's analysis found that survival is increased for subjects having hypercholesterolemia (RR = 0.565), NAFLD (RR = 0.777), hypertension (RR = 0.711) and in female (RR = 0.741), while it is decreased for the older subjects (RR = 3.046), in patients with hypertriglyceridemia (RR = 1.699) and for diabetics (RR = 1.797). The variables BMI and HDL-cholesterol have no role. CONCLUSION: The data obtained in our study show that NAFLD is not associated to overall mortality in the elderly population.

Probable Etoricoxib-Induced Severe Thrombocytopenia: A Case Report.

OBJECTIVE: To describe a case of likely etoricoxib-induced severe thrombocytopenia. CLINICAL PRESENTATION AND INTERVENTION: A 32-year-old woman was referred to our hospital for disseminated petechial rash after 7 days of therapy with etoricoxib. At admission, the patient's platelet count was 3,000/mm3. At Naranjo's scale correlation between thrombocytopenia and drug was considered as "probable." With the diagnostic tests performed we did not find other causes of thrombocytopenia. Etoricoxib was discontinued. The patient was treated with intravenous immunoglobulin and corticosteroids with a complete resolution of the thrombocytopenia in a few days. CONCLUSION: The prevalence of thrombocytopenia induced by etoricoxib should be studied as it may not be very rare.

Accuracy of Lung Ultrasound in Patients with Acute Dyspnea: The Influence of Age, Multimorbidity and Cognitive and Motor Impairment.

Discriminating between causes of dyspnea may be difficult, particularly in the elderly. The aim of this retrospective study of 83 inpatients with acute dyspnea was to assess the influence of age, multimorbidity and cognitive or motor impairment on the diagnostic accuracy of lung ultrasound (LUS) in discriminating acute heart failure (AHF) from noncardiogenic dyspnea (NCD). Univariate analysis indicates that LUS misdiagnosis was associated with the following parameters: history of stroke (p = 0.037), lower activity of daily living (p = 0.039), higher modified-Rankin scale (mRS) (p = 0.027) and need of two operators to complete LUS because of reduced patient compliance (p = 0.030). Regression analysis identified only history of stroke (p = 0.048) as an independent predictor of LUS misdiagnosis. This study supports LUS usefulness to differentiate AHF from NCD. Our data suggest that diagnostic accuracy of LUS is affected by history of stroke as a proxy for severe motor impairment but not by age, cognitive impairment and multimorbidity.
