A novel coronavirus emerged this year as a cause of viral pneumonia. The main characteristics of the virus are rapid transmission, high contagion capacity and potential severity. The objective of this case series study is to describe the clinical characteristics of patients with confirmed coronavirus disease (COVID-19) admitted to different intensive care units in Argentina for mechanical ventilation.
A descriptive, prospective, multicenter case series study was conducted between April 1 and May 8, 2020. Data from patients older than 18 years who were admitted to the intensive care unit for mechanical ventilation for acute respiratory failure with a positive diagnosis of COVID-19 were included.
The variables for 47 patients from 31 intensive care units were recorded: 78.7% were men (median age of 61 years), with a SAPS II score of 43 and a Charlson index score of 3. The initial ventilatory mode was volume control - continuous mandatory ventilation with a tidal volume less than 8mL/kg in 100% of cases, with a median positive end-expiratory pressure of 10.5cmH2O. At the end of the study, 29 patients died, 8 were discharged, and 10 remained hospitalized. The SAPS II score was higher among patients who died (p = 0.046). Charlson comorbidity index was associated with higher mortality (OR = 2.27, 95% CI 1.13 - 4.55, p = 0.02).
Patients with COVID-19 and on mechanical ventilation in this series presented clinical variables similar to those described to date in other international reports. Our findings provide data that may predict outcomes.

Little evidence exists to support the use of noninvasive mechanical ventilation for acute hypoxemic respiratory failure. However, considering the complications associated with endotracheal intubation, we attempted to implement noninvasive mechanical ventilation in a 24-year-old patient who was 32 weeks pregnant and was admitted to the intensive care unit with acute hypoxemic respiratory failure and sepsis secondary to a urinary tract infection. Lack of tolerance to noninvasive mechanical ventilation led us to use an alternative method to avoid endotracheal intubation. The use of high-flow nasal cannula allowed to overcome this situation, wich supports this technique as a treatment option for critical obstetric patients that is safe for both the mother and fetus.

BACKGROUND AND OBJECTIVES: Strongyloides Stercoralis is a common cause of gastrointestinal infection. This nematode can produce an overwhelming hyperinfection syndrome, especially in the immunocompromised patient. Typically, patients present with pulmonary symptoms, but subsequently they can acquire Gram-negative sepsis. The objective of this report is to describe a lethal case and call attention to the importance of early diagnosis and treatment. CASE REPORT: Male patient, 60 year-old with diagnosis of timoma, treated with surgery, radiotherapy and chemotherapy in the past. He presented to the emergency room complaining of diarrhea and dyspnea, and then transferred to the ICU after development of hypoxemic acute respiratory failure and refractory septic shock, and despite treatment the patient died. A bronchial sample of sputum showed Strongyloides stercoralis worms. CONCLUSIONS: Strongyloides stercoralis infection symptoms are usually mild, but in the setting of impaired host immunity, a disseminated and severe illness may occur. Clinicians must be aware for patients from endemic areas. Diagnosis may be established through sputum and stool examination for Strongyloides stercoralis worms.
