Abstract Background The very old patients (≥ 80 years-old, VOP) comprise a subpopulation increasingly admitted to intensive care units (ICUs). Community-acquired pneumonia (CAP) is a common reason for admission and the best strategy of mechanical ventilation for respiratory failure in this scenario is not fully known. Methods Multicenter cohort study of VOPs admitted with CAP in need of invasive (IMV) or noninvasive (NIV) mechanical ventilation to 11 Brazilian ICUs from 2009 through 2012. We used logistic regression models to evaluate the association between ventilator strategy (NIV vs. IMV) and hospital mortality adjusting for confounding factors. We evaluated effect modification with interaction terms in pre-specified sub-groups. Results Of 369 VOPs admitted for CAP with respiratory failure, 232 (63%) received NIV and 137 (37%) received IMV as initial ventilatory strategy. IMV patients were sicker at ICU admission (median SOFA 8 vs. 4, p < 0.001). Hospital mortality was 114/232 (49%) for NIV and 90/137 (66%) for IMV. For the comparison NIV vs. IMV (reference), the crude odds ratio (OR) was 0.50 (95% CI, 0.33–0.78, p=0.002). This association was largely confounded by antecedent characteristics and non-respiratory SOFA (adjOR = 0.70, 95% CI, 0.41–1.20, p=0.196). The fully adjusted model, including Pao2/Fio2 ratio, pH and Paco2, yielded an adjOR of 0.81 (95% CI, 0.46–1.41, p=0.452). There was no strong evidence of effect modification among relevant subgroups, such as Pao2/Fio2 ratio ≤ 150 (p = 0.30), acute respiratory acidosis (p = 0.42) and non-respiratory SOFA ≥ 4 (p = 0.53). Conclusions NIV was not associated with lower hospital mortality when compared to IMV in critically ill VOP admitted with CAP, but there was no strong signal of harm from its use. The main confounders of this association were both the severity of respiratory dysfunction and of extra-respiratory organ failures.

Purpose: Septic patients are at risk for hypotension, and this risk may increase during rapid sequence intubation (RSI). Sedatives such as propofol must be used carefully due to its ability to reduce vascular sympathetic tone. Since the safety of propofol for RSI is not well described in sepsis, this was a study evaluating propofol and its effects on hemodynamics when used for RSI in a septic population. Materials and methods: We conducted a multicenter, retrospective, cohort study of patients with sepsis or severe sepsis requiring sedation for RSI. Patients receiving a propofol bolus for RSI were compared to patients undergoing RSI without a propofol bolus. The safety profile of propofol was evaluated according to the rates of post-intubation hypotension and vasopressor utilization between groups. Results: A total of 179 patients (79 propofol, 100 non-propofol) were evaluated. There were no differences in hypotension (81% vs 78%; P = .62) or vasopressor utilization between the propofol and non-propofol groups (43% vs 49%; P = .43). Patients in the non-propofol group had increased APACHE II scores and healthcare-associated infections. Conclusions: In this cohort study, administration of propofol for RSI in patients with sepsis and severe sepsis did not increase incidence of hypotension or vasopressor use, but acute illness may have introduced provider selection bias causing less propofol use in the non-propofol group. Larger prospective studies are needed to better characterize the adverse hemodynamic effects of propofol, before propofol bolus doses for RSI can be considered for safe use in this population.

ABSTRACTIn this retrospective multicenter cohort study, we aimed to investigate the association between antihypertensive agent exposure and in-hospital mortality in patients with Covid-19. Of 8,078 hospitalized patients for Covid-19, 3,686 (45.6%) had hypertension including 2043 (55.4%) patients exposed to a renin-angiotensin-aldosterone inhibitors (RAASi), 1624 (44.1%) to calcium channel blockers (CCB) and 1154 (37.7%) to beta-blockers. Overall in-hospital 30-day mortality was 23.1%. Compared to non-users, the risk of mortality was lower in CCB (aOR, 0.83 [0.70-0.99]) and beta-blockers users (aOR, 0.80 [0.67-0.95]), and not different in RAASi users. These findings support the continuation of antihypertensive agents in patients with Covid-19.

AbstractBackground and purposeThe frequency of ischemic stroke in patients with COVID-19 varies in the current literature, and risk factors are unknown. We assessed the incidence, risk factors, and outcomes of acute ischemic stroke in hospitalized patients with COVID-19.MethodsWe included patients with a laboratory confirmed SARS-CoV-2 infection admitted in 16 hospitals participating in the international CAPACITY-COVID registry between March 1st and August 1st, 2020. Patients were screened for the occurrence of acute ischemic stroke. We calculated the cumulative incidence of ischemic stroke and compared risk factors, cardiovascular complications, and in-hospital mortality in patients with and without ischemic stroke.ResultsWe included 2147 patients with COVID-19, of whom 586 (27.3%) needed treatment at an intensive care unit (ICU). Thirty-eight patients (1.8%) had an ischemic stroke. Patients with stroke were older, but did not differ in sex or cardiovascular risk factors. Median time between onset of COVID-19 symptoms and diagnosis of stroke was two weeks. The incidence of ischemic stroke was higher among patients who were treated at an ICU (16/586; 2.7% versus 22/1561; 1.4%; p=0.039). Pulmonary embolism was more common in patients with (8/38; 21.1%) than in those without stroke (160/2109; 7.6%; adjusted RR: 2.08; 95%CI:1.52-2.84). Twenty-seven patients with ischemic stroke (71.1%) died during admission or were functional dependent at discharge and in-hospital mortality. Patients with ischemic stroke were at a higher risk of in-hospital mortality (adjusted RR 1.56; 95%CI:1.13-2.15) than patients without stroke.ConclusionsIn this multicenter cohort study, the cumulative incidence of acute ischemic stroke in hospitalized patients with COVID-19 was approximately 2%, with a higher risk in patients treated at an ICU. The majority of stroke patients had a poor outcome. The association between ischemic stroke and pulmonary embolism warrants further investigation.
