Objective. Currently, management of acute respiratory distress syndrome (ARDS) in COVID-19 infection with invasive mechanical ventilation results in poor prognosis and high mortality rates. Interventions to reduce ventilatory requirements or preclude their needs should be evaluated in order to improve survival rates in critically ill patients. Formation of neutrophil extracellular traps (NETs) during the innate immune response could be a contributing factor to the pulmonary pathology. This study suggests the use of dornase alfa, a recombinant DNAse I that lyses NETs, to reduce ventilatory requirements and improve oxygenation status, as well as outcomes in critically ill patients with ARDS subsequent to confirmed or highly suspected COVID-19 infection. Design. A single-institution cohort study. Setting. Intensive care unit in a tertiary medical center. Patients. Adult patients with acute respiratory distress syndrome (ARDS) admitted to the ICU with confirmed COVID-19 infection. Intervention. Treatment with aerosolized dornase alfa. Measurements and Main Results. Of 39 patients evaluated, most patients had improvement in oxygenation measured by increase in the PaO2/FiO2 ratio, reduction in ventilatory support or other supportive oxygen requirements, and partial resolution of bilateral opacities visible on CXR, as well as improved outcome. Conclusions. Administration of inhalational dornase alfa via a filtered nebulizer medication system or through an adapter in a ventilator circuit should be considered in all COVID-19-positive patients with ARDS as early in the disease course as possible.
The aim of this study is to evaluate the impact of transoral robotic surgery (TORS) compared to nonrobotic surgery (NRS) on overall survival in oropharyngeal squamous cell carcinoma (OPSCC). We performed a retrospective study of patients with HPV+ and HPV− OPSCC undergoing TORS or NRS with neck dissection using the National Cancer Database from the years 2010–2016. Among patients with OPSCC in our cohort, 3167 (58.1%) patients underwent NRS and 2288 (41.9%) underwent TORS. TORS patients demonstrated better overall survival than NRS patients (HPV+ patients: aHR 0.74, p = 0.02; HPV− patients: aHR 0.58, p < 0.01). Subsite analysis showed TORS was correlated with improved survival in base of tongue (BoT) primaries for both HPV+ (aHR 0.46, p = 0.01) and HPV− (aHR 0.42, p = 0.01) OPSCC. Compared to NRS, TORS is associated with improved overall survival for HPV+ and HPV− OPSCC, as well as greater overall survival for BoT primaries.
Background
Head and neck osteosarcoma (HNOS) is a rare primary bone tumor with limited data to guide treatment approaches.
Methods
The NCDB was used to identify patients diagnosed with HNOS. Kaplan–Meier and Cox multivariate regression were used to examine the impact of each treatment on overall survival (OS).
Results
We identified 821 patients diagnosed with HNOS. Utilization of neoadjuvant chemotherapy + surgery increased from zero cases in 2004 to 24% of cases in 2016. Among surgically treated patients, 5‐year OS was 55.8% (CI: 51.7–60.1%). No difference was seen in OS between each treatment cohort on multivariate analysis. However, neoadjuvant chemotherapy + surgery + adjuvant chemotherapy had improved 18‐month survival compared to surgery alone (95.8% vs. 78.5%, p = 0.031).
Conclusions
Our study demonstrated no survival benefit in perioperative chemotherapy or radiation therapy; however, short‐term survival improvement in patients receiving both neoadjuvant and adjuvant chemotherapy displays promise and requires further investigation.
