Effect of famotidine on hospitalized patients with COVID-19: A systematic review and meta-analysis.

INTRODUCTION: Famotidine is a competitive histamine H2-receptor antagonist most commonly used for gastric acid suppression but thought to have potential efficacy in treating patients with Coronavirus disease 2019 (COVID-19). The aims of this systematic review and meta-analysis are to summarize the current literature and report clinical outcomes on the use of famotidine for treatment of hospitalized patients with COVID-19. METHODS: Five databases were searched through February 12, 2021 to identify observational studies that reported on associations of famotidine use with outcomes in COVID-19. Meta-analysis was conducted for composite primary clinical outcome (e.g. rate of death, intubation, or intensive care unit admissions) and death separately, where either aggregate odds ratio (OR) or hazard ratio (HR) was calculated. RESULTS: Four studies, reporting on 46,435 total patients and 3,110 patients treated with famotidine, were included in this meta-analysis. There was no significant association between famotidine use and composite outcomes in patients with COVID-19: HR 0.63 (95% CI: 0.35, 1.16). Across the three studies that reported mortality separated from other endpoints, there was no association between famotidine use during hospitalization and risk of death-HR 0.67 (95% CI: 0.26, 1.73) and OR 0.79 (95% CI: 0.19, 3.34). Heterogeneity ranged from 83.69% to 88.07%. CONCLUSION: Based on the existing observational studies, famotidine use is not associated with a reduced risk of mortality or combined outcome of mortality, intubation, and/or intensive care services in hospitalized individuals with COVID-19, though heterogeneity was high, and point estimates suggested a possible protective effect for the composite outcome that may not have been observed due to lack of power. Further randomized controlled trials (RCTs) may help determine the efficacy and safety of famotidine as a treatment for COVID-19 patients in various care settings of the disease.

A Multidisciplinary Approach and Review of Safety Recommendations for Plastic Surgeons during the COVID-19 Pandemic: Are N95 Masks Enough?

SUMMARY: The novel coronavirus disease of 2019 pandemic presents a unique challenge to the field of plastic and reconstructive surgery. Although plastic surgeons may be postponing elective operations, there are still a number of emergent or urgent procedures that may need to be performed, and surgeons may be facing the reality of returning to a new normalcy of operating with coronavirus disease of 2019. These procedures, consisting of those such as head and neck reconstruction or maxillofacial trauma, largely require a multidisciplinary approach and may be considered of higher risk to health care workers because of the involvement of areas of the body identified as sources for viral transmission. Moreover, viral transmission may potentially extend beyond respiratory secretions, which has been the main focus of most safety precautions. The authors aim to present the scope of these procedures and the means of viral transmission, and to provide safety precaution recommendations for plastic surgery and its related disciplines.

Decline in Rehab Transfers Among Rehab-Eligible Stroke Patients During the COVID-19 Pandemic.

OBJECTIVE: To characterize differences in disposition arrangement among rehab-eligible stroke patients at a Comprehensive Stroke Center before and during the COVID-19 pandemic. MATERIALS AND METHODS: We retrospectively analyzed a prospective registry for demographics, hospital course, and discharge dispositions of rehab-eligible acute stroke survivors admitted 6 months prior to (10/2019-03/2020) and during (04/2020-09/2020) the COVID-19 pandemic. The primary outcome was discharge to an inpatient rehabilitation facility (IRF) as opposed to other facilities using descriptive statistics, and IRF versus home using unadjusted and adjusted backward stepwise logistic regression. RESULTS: Of the 507 rehab-eligible stroke survivors, there was no difference in age, premorbid disability, or stroke severity between study periods (p>0.05). There was a 9% absolute decrease in discharges to an IRF during the pandemic (32.1% vs. 41.1%, p=0.04), which translated to 38% lower odds of being discharged to IRF versus home in unadjusted regression (OR 0.62, 95%CI 0.42-0.92, p=0.016). The lower odds of discharge to IRF persisted in the multivariable model (aOR 0.16, 95%CI 0.09-0.31, p<0.001) despite a significant increase in discharge disability (median discharge mRS 4 [IQR 2-4] vs. 2 [IQR 1-3], p<0.001) during the pandemic. CONCLUSIONS: Admission for stroke during the COVID-19 pandemic was associated with a significantly lower probability of being discharged to an IRF. This effect persisted despite adjustment for predictors of IRF disposition, including functional disability at discharge. Potential reasons for this disparity are explored.

Posterior reversible encephalopathy syndrome (PRES) associated with COVID-19.

The novel human coronavirus disease (COVID-19) has been associated with vascular and thrombotic complications, some of which may result from endothelial dysfunction, including the posterior reversible encephalopathy syndrome (PRES). We report a case series of 8 patients with COVID-19 and PRES diagnosed at two academic medical centers between March and July of 2020. The clinical, laboratory and radiographic data, treatment, and short-term outcomes were retrospectively analyzed. The mean age was 57.9 ± 12 years, and 50% were women. Four patients had previous vascular comorbidities. All the patients suffered from severe pneumonia, requiring intensive care unit admission. Five patients were not hypertensive at presentation (all SBP < 127 mmHg). Neurologic symptoms included seizures in 7 patients; impaired consciousness in 5 patients; focal neurological signs in 3 patients; and visual disturbances in 1 patient. All patients underwent brain magnetic resonance imaging which indicated asymmetric T2 prolongation or diffusion changes (50%), extensive fronto-parieto-occipital involvement (25%), vascular irregularities (12.5%) and intracranial hemorrhage (25%). Four patients were treated with tocilizumab. Three patients were discharged without neurologic disability, 2 patients had persistent focal neurologic deficits and 2 expired. One patient's prognosis remains guarded. Together, these data support the relationship between PRES and endothelial dysfunction associated with severe COVID-19. In patients with severe COVID-19, PRES can be triggered by uncontrolled hypertension, or occur independently in the setting of systemic illness and certain medications. Like other infectious processes, critically ill patients with COVID-19 may be at greater risk of PRES because of impaired vasoreactivity or the use of novel agents like Tocilizumab.

Plastic Surgery in the Time of COVID-19.

BACKGROUND: The novel coronavirus disease 2019 (COVID-19) has swept the world in the last several months, causing massive disruption to existing social, economic, and health care systems. As with all medical fields, plastic and reconstructive surgery has been profoundly impacted across the entire spectrum of practice from academic medical centers to solo private practice. The decision to preserve vital life-saving equipment and cancel elective procedures to protect patients and medical staff has been extremely challenging on multiple levels. Frequent and inconsistent messaging disseminated by many voices on the national stage often conflicts and serves only to exacerbate an already difficult decision-making process. METHODS: A survey of relevant COVID-19 literature is presented, and bioethical principles are utilized to generate guidelines for plastic surgeons in patient care through this pandemic. RESULTS: A cohesive framework based upon core bioethical values is presented here to assist plastic surgeons in navigating this rapidly evolving global pandemic. CONCLUSION: Plastic surgeons around the world have been affected by COVID-19 and will adapt to continue serving their patients. The lessons learned in this present pandemic will undoubtedly prove useful in future challenges to come.
