At this time, there is no specific therapeutic or vaccine for treatment of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Hence, available drugs for treatment of other viral infections may be useful to treat COVID-19.

The focus of the current review was studying the main characteristics of favipiravir and its usefulness to treat COVID-19. An electronic search was done by using Pubmed and Google scholar.

Based on the mechanism of action and safety of favipiravir, the drug may be a promising candidate for compassionate use against the SARS-CoV-2 infection. Favipiravir has a wide range of activity against many single-stranded RNA viruses, is well tolerated in humans and has a high barrier to resistance. However, high doses of the agent are necessary to obtain an efficient antiviral activity. Favipiravir is teratogen in pregnant women and associated with the hyperuricemia. Therefore, the administration of the drug should be well controlled. Investigating the antiviral prophylactic potency of favipiravir and search for its pro-drugs and/or analogs showing improved activity and/or safety are critical.

Genetic screening was performed to detect the sequence variations in the retinal dystrophy associated genes in the patient and his parents.Results The patient demonstrated the characteristic full-field electroretinography (ERG) features of CDSRR, namely a profound enlargement of the dark-adapted ERG b-wave amplitude with increasing flash strength and a broadened a-wave trough; this case also had undetectable light-adapted ERGs. A BCVA of 0.15 was maintained over 5 years in both eyes; while progressive macular atrophy was identified. Molecular genetic analyses revealed two novel disease-causing KCNV2 variants in compound heterozygous state c.1408 G > C (p.Gly470Arg) and c.1500 C > G (p.Tyr500Ter).Conclusions This is the first long-term case study of an East Asian patient with molecularly confirmed CDSRR. The progressive atrophy with maintained VA demonstrated in this case will be valuable for increasing the understanding of the natural course of KCNV2 retinopathy and it will help in counselling patients with this disease.

Pediatric cardiac Extracorporeal Membrane Oxygenation (ECMO) is effective, however, bleeding and clotting issues continue to cause significant morbidity and mortality. The objective of this study was to assess the correlation between measures of anticoagulation, the heparin dose in pediatric cardiac ECMO patients as well as to assess covert coagulopathy as measured by thromboelastography (TEG).

Retrospective study of cardiac ECMO patients in a large, academic referral center using anticoagulation data during the ECMO support.

Five hundred and eighty-four sets of anticoagulation tests and 343 TEG from 100 patients with median age of 26 days were reviewed. ECMO was post-surgical for congenital heart disease in 94% with resuscitation (ECPR) in 38% of the cases. Mean duration of support was 6.3 days. selleck chemical Overall survival to discharge was 35%. There was low but statistically significant correlation between individual anticoagulation measures and low correlation between Anti-Xa levels and heparin dose. There was no correlation between PTT and heparin dose. 343 TEG with Heparinase were reviewed to assess covert coagulopathy which was present in 25% of these. The coagulopathy noted was pro-hemorrhagic in almost all of the cases with high values of reaction time and kinetics and low values for angle and maximum amplitude.

Coagulation monitoring on ECMO may benefit from addition of Heparinase TEG to diagnose covert coagulopathy which can contribute to significant hemorrhagic complications. There is a need for a prospective, thromboelastography guided intervention trial to reduce coagulopathy related morbidity and mortality in ECMO.

We used latent class analysis (LCA) to identify risk profiles in localized, malignant PCa surgical treatment delays while assessing co-occurring social determinants of health. Profiles were identified by age, marital status, race, county of residence (non-Appalachian or Appalachian), and health insurance type (none/self-pay, public, or private) reported in the Tennessee Department of Health cancer registry from 2005 to 2015 for adults ≥18 years (N = 18,088). We identified three risk profiles. The highest surgical delay profile (11% of the sample) with a 30% likelihood of delaying surgery >90 days were young Black men, less then 55 years old, living in a non-Appalachian county, and single/never married, with a high probability of having private health insurance. The medium surgical delay profile (46% of the sample) with a 21% likelihood of delay were 55-69 years old, White, married, and having private health insurance.
