Objectives: Angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin receptor blockers (ARBs) are the most commonly prescribed antihypertensives, with prior studies identifying a possible association between long-term use and increased rates of lung cancer. This study evaluated this potential association in a large population using propensity matching.Methods: This was a population-based cohort study in a large healthcare system in three regions of the United States. Pairwise propensity score matching was performed using demographics and comorbidities. All of the adult patients in the healthcare system from January 1, 2000 to April 30, 2018 with at least 1 year of follow-up were included.Results: In total, 3,253,811 patients with a median age of 59 (range 18-103) years were included. The ACEI group had a higher freedom from lung cancer versus controls at 15 years (98.47%, 95% confidence interval [CI] 98.41-98.54) versus 98.26%, (95% CI 98.20-98.33), whereas ARBs had similar rates versus controls at all time points. For patients diagnosed as having lung cancer, median all-cause survival was significantly higher in the ACEI (34.7 months, 95% CI 32.8-36.6) and ARB (30.9 months, 95% CI 28.1-33.8) groups than the control group (20.6 months,.Conclusions: This study showed lower rates of lung cancer with ACEI use and no difference in risk with ARBs. In addition, use of these medications was found to be associated with increased survival in those diagnosed as having lung cancer. This study supports the continued use of these medications without concern for increasing the risk of lung cancer.
Objectives Palliative Medicine involvement in MICU patients have improved length of stay and mortality, but with varying effects on specific patient decision outcomes, such as, advance care planning. These studies have utilized Palliative Medicine later in the hospital or ICU course, with some evidence showing that earlier involvement resulted in better results. The purpose of this study was to evaluate the benefits of early (within 24 hours) palliative care consultation in medical ICU (MICU) patients to clinical and satisfaction outcomes. Methods An unblinded randomized study performed in the MICU in one academic hospital in the USA. Ninety-one adult patients admitted to MICU received a Palliative care medicine consultation within 24 hours as the intervention. Measurements and results Ninety-one patients admitted to the MICU underwent randomization with 50 patients randomly assigned to receive Palliative Medicine consultation and 41 patients randomly assigned to receive standard-of-care based on predefined criteria. The median satisfaction score was 23 points higher for the patients in the intervention group (P < .001). The median length of MICU stay was 5 days shorter in the intervention group compared to the control group (95% CI; 1 day to 18 days, P = .018). Advance care planning was completed in the hospital for 34% of patients in the intervention arm and 12% of patients in the controls arm (absolute risk difference 22%, 95% CI 4% to 37%, P = .016). Conclusion Early Palliative Medicine consultation within 24 hours of MICU admission showed significant benefits to patients by improving satisfaction and decreasing length of stay. This study provides evidence that Palliative Medicine involvement earlier in the course of severe disease is important. Further studies in other types of intensive care units (neurological and Cardiovascular) are necessary to determine their impact.
Case series
Patients: Female, 21-year-old • Female, 53-year-old • Male, 38-year-old
Final Diagnosis: ARDS • COVID pneumonia
Symptoms: Respiratory failure • sepsis • shock
Medication: —
Clinical Procedure: High-frequency oscillatory ventilation (HFOV) • mechanical ventilation • oscillator
Specialty: Critical Care Medicine
Objective:
Unusual clinical course
Background:
COVID-19 continues to place a tremendous burden on the healthcare system, with most deaths resulting from respiratory failure. Management strategies have varied, but the mortality rate for mechanically ventilated patients remains high. Conventional management with ARDSnet ventilation can improve outcomes but alternative and adjunct treatments continue to be explored. High-frequency oscillatory ventilation (HFOV), a modality now rarely used in adult critical care medicine, may offer an alternative treatment option by maximizing lung protection and limiting oxygen toxicity in critically ill patients failing conventional ventilator strategies.
Case Reports:
We present 3 patients with severe acute respiratory distress syndrome (ARDS) and sepsis due to COVID-19 who all improved clinically after transitioning from conventional ventilation to HFOV. Two patients developed refractory hypoxemia with hemodynamic instability and multiple organ failure requiring vasopressor support and renal replacement therapy. After failing to improve with all available therapies, both patients stabilized and ultimately improved after being placed on HFOV. The third patient developed severe volutrauma/barotrauma despite extreme lung protection and ARDSnet ventilation. He showed improvement in oxygenation and signs of lung trauma slowly improved after initiating HFOV. All 3 patients were ultimately liberated from mechanical ventilation and discharged from the hospital to return to functional independence.
Conclusions:
Our experience suggests that HFOV offers advantages in the management of certain critically ill patients with ARDS due to COVID-19 pneumonia and might be considered in cases refractory to standard management strategies.
