Tocilizumab in patients admitted to hospital with COVID-19 (RECOVERY): preliminary results of a randomised, controlled, open-label, platform trial (preprint)

Findings: Between 23 April 2020 and 25 January 2021, 4116 adults were included in the assessment of tocilizumab, including 562 (14%) patients receiving invasive mechanical ventilation, 1686 (41%) receiving non-invasive respiratory support, and. 1868 (45%) receiving no respiratory support other than oxygen. Median CRP was 143 [IQR 107-205] mg/L and 3385 (82%) patients were receiving systemic corticosteroids at randomisation. Overall, 596 (29%) of the 2022 patients allocated tocilizumab and 694 (33%) of the 2094 patients allocated to usual care died within 28 days (rate ratio 0.86; 95% confidence interval [CI] 0.77-0.96; p=0.007). Consistent results were seen in all pre-specified subgroups of patients, including those receiving systemic corticosteroids. Patients allocated to tocilizumab were more likely to be discharged from hospital alive within 28 days (54% vs. 47%; rate ratio 1.23; 95% CI 1.12-1.34; p<0.0001). Among those not receiving invasive mechanical ventilation at baseline, patients allocated tocilizumab were less likely to reach the composite endpoint of invasive mechanical ventilation or death (33% vs. 38%; risk ratio 0.85; 95% CI 0.78-0.93; p=0.0005). Interpretation: In hospitalised COVID-19 patients with hypoxia and systemic inflammation, tocilizumab improved survival and other clinical outcomes regardless of the level of respiratory support received and in addition to the use of systemic corticosteroids.

Fibrinolytic Strategy for ST-Segment-Elevation Myocardial Infarction: A Contemporary Review in Context of the COVID-19 Pandemic.

The ongoing coronavirus disease 2019 pandemic has resulted in additional challenges for systems designed to perform expeditious primary percutaneous coronary intervention for patients presenting with ST-segment-elevation myocardial infarction. There are 2 important considerations: the guideline-recommended time goals were difficult to achieve for many patients in high-income countries even before the pandemic, and there is a steep increase in mortality when primary percutaneous coronary intervention cannot be delivered in a timely fashion. Although the use of fibrinolytic therapy has progressively decreased over the last several decades in high-income countries, in circumstances when delays in timely delivery of primary percutaneous coronary intervention are expected, a modern fibrinolytic-based pharmacoinvasive strategy may need to be considered. The purpose of this review is to systematically discuss the contemporary role of an evidence-based fibrinolytic reperfusion strategy as part of a pharmacoinvasive approach, in the context of the emerging coronavirus disease 2019 pandemic.

Finding the Calm in the Chaos: An Institutional Protocol for Anesthetic Management of a Patient for Neurosurgery during Coronavirus Disease 2019 Pandemic.

"Coronavirus disease 2019" (COVID-19) transmitted by a novel coronavirus via contact or droplet spread is a highly infectious disease, the containment of which requires vigilance and stringent infection control policies. In the backdrop of hospitals becoming hot zones and an increasing number of health care workers contracting the disease, it is crucial to formulate an approach while administering anesthesia during the testing times of COVID-19 pandemic. In this background, this comprehensive article deals with the perioperative management during this pandemic and includes risk stratification based on an innovative simple scoring system, rationale use of personal protective equipments, and infection prevention protocols. The document of updated literature, though not intended to replace any guidelines, is aimed at providing protocol to health care workers to protect themselves while providing the best care in this pandemic.

Impact of COVID-19 pandemic on STEMI care: An expanded analysis from the United States.

OBJECTIVE: To evaluate the impact of COVID-19 pandemic migitation measures on of ST-elevation myocardial infarction (STEMI) care. BACKGROUND: We previously reported a 38% decline in cardiac catheterization activations during the early phase of the COVID-19 pandemic mitigation measures. This study extends our early observations using a larger sample of STEMI programs representative of different US regions with the inclusion of more contemporary data. METHODS: Data from 18 hospitals or healthcare systems in the US from January 2019 to April 2020 were collecting including number activations for STEMI, the number of activations leading to angiography and primary percutaneous coronary intervention (PPCI), and average door to balloon (D2B) times. Two periods, January 2019-February 2020 and March-April 2020, were defined to represent periods before (BC) and after (AC) initiation of pandemic mitigation measures, respectively. A generalized estimating equations approach was used to estimate the change in response variables at AC from BC. RESULTS: Compared to BC, the AC period was characterized by a marked reduction in the number of activations for STEMI (29%, 95% CI:18-38, p < .001), number of activations leading to angiography (34%, 95% CI: 12-50, p = .005) and number of activations leading to PPCI (20%, 95% CI: 11-27, p < .001). A decline in STEMI activations drove the reductions in angiography and PPCI volumes. Relative to BC, the D2B times in the AC period increased on average by 20%, 95%CI (-0.2 to 44, p = .05). CONCLUSIONS: The COVID-19 Pandemic has adversely affected many aspects of STEMI care, including timely access to the cardiac catheterization laboratory for PPCI.
