RESUMO
Respiratory failure (RF) is frequent in hospitalized older patients, but was never systematically investigated in large populations of older hospitalized patients. We conducted a retrospective administrative study based on hospitalizations of a Geriatrics Unit regarding 2014, 2015, and 2016. Patients underwent daily screening for hypoxia. Hospital discharge records were coded through a standardized methodology. RF, defined as documented hypoxia on room air, was always coded, whenever present. We investigated how RF affected clinical outcomes, whether RF grouped into specific comorbidity phenotypes, and how phenotypes associated with the outcomes. RF was coded in 48.6% of the 1,810 hospitalizations. RF patients were older and more frequently had congestive heart failure (CHF: 49 vs 23%), chronic obstructive pulmonary disease (COPD: 27 vs 6%), pneumonia (14 vs 4%), sepsis (12 vs 7%), and pleural effusion (6 vs 3%), than non-RF patients. RF predicted longer length of stay (a-Beta 2.05, 95% CI 1.4-2.69; p < 0.001) and higher in-hospital death/intensive care units (ICU) need (aRR 7.12, 5-10.15; p < 0.001) after adjustment for confounders (linear and Poisson regression with robust error variance). Among RF patients, cerebrovascular disease, cancer, electrolyte disturbances, sepsis, and non-invasive ventilation predicted increased, while CHF and COPD predicted decreased in-hospital death/ICU need. The ONCO (cancer) and Mixed (cerebrovascular disease, dementia, pneumonia, sepsis, electrolyte disturbances, bedsores) phenotypes displayed higher in-hospital death/ICU need than CARDIO (CHF) and COPD phenotypes. In this study, RF predicted increased hospital death/ICU need and longer hospital stay, but also reflected diverse underlying conditions and clinical phenotypes that accounted for different clinical courses.

Recent data have shown a higher incidence of arterial events in patients with venous thromboembolism (VTE) of unknown origin than in those with the secondary form of disease. Whether patients with idiopathic VTE have a higher risk of subsequent arterial events than the general population is unknown. The aim was to evaluate the rates of subsequent arterial events in patients with idiopathic VTE and control subjects. In a retrospective cohort study we compared the rates of subsequent arterial events (i.e. acute myocardial infarction, ischemic stroke and peripheral arterial disease) in 151 consecutive patients with objectively confirmed spontaneous VTE and 151 control subjects randomly selected from the database of two family physicians. We collected information about cardiovascular risk-factors (hypertension, hypercholesterolemia, diabetes, obesity and smoke) at the time of VTE episode, or corresponding date for the controls, and considered the follow-up from this time. Patients and controls who had suffered from arterial events before the index date were excluded. During a mean follow-up of 43.1 (+/- 21.7) months there were 16 arterial events in the VTE patients and six in the control group (HR, 2.84;95% CI,1.11 to 7.27; p = 0.03). The difference remained significant after adjusting for age and other cardiovascular risk factors (HR 2.86;95% CI,1.07 to 7.62). Overall mortality was also higher in the VTE patients (12 vs.4 deaths). In conclusion, arterial events are more common in patients with previous idiopathic VTE than in the general population. These findings may have practical implications.

To determine the prognostic importance of troponin T in normotensive patients with pulmonary embolism, we investigated the rate of adverse events in patients with normal and elevated troponin values, during the hospital period and at three months of follow-up. We also calculated the proportion of patients with abnormal troponin values and adverse outcomes who could have been treated with more aggressive therapy according to published criteria.

There is little information available about the true incidence of post-thrombotic syndrome (PTS) after pulmonary embolism (PE). The aim of this study was to investigate the incidence of PTS in patients with previous pulmonary embolism without concomitant ultrasonographically-detectable deep vein thrombosis (DVT). A retrospective cohort study was conducted at a single tertiary care centre, Cosenza, Italy. Forty-seven consecutive patients with proved PE without DVT within the previous 2 to 6 years, 45 patients with previous DVT in the same years, and 45 patients with diseases unrelated to venous thromboembolism (VTE) underwent a blind assessment for PTS using a clinical score. Two of 47 (4.2%, 95%CI: 0.01-9.9) patients with PE, 2 of 45 (4.4%, 95%CI: 0.01-10.4) patients with diseases unrelated to VTE, and 23 of 45 (53.3%, 95%CI: 38.7-67.9) patients with DVT showed signs and symptoms of PTS. The difference between the first two groups was not statistically significant (p = 0.7). In conclusion, the incidence of PTS after pulmonary embolism without DVT is low, and no different from that of patients without previous VTE.
