ECMO is a selectively available therapeutic option, generally at a large-size referral healthcare system. In a single-center experience of use of veno-venous ECMO for COVID-19 ARDS in a medium-size healthcare system during the pandemic, West and colleagues in their study have convincingly demonstrated that ECMO can become a broadly available therapeutic option without compromising quality.

Fluvoxamine is a selective-serotonin reuptake inhibitor (SSRI), well-tolerated and widely available, usually used in the management of mental-health conditions. Fluvoxamine is also a sigma-1 agonist with high affinity to this receptor and this pharmacodynamical effect has been being portrayed as the main explanation in emerging evidence about the potential of using fluvoxamine in COVID-19 patients. This systematic review was conducted according to the PRISMA guidelines. The search was run in MEDLINE, Web of Science, and CENTRAL from the Cochrane databases. The study protocol was registered in PROSPERO (CRD42022302025). Our aim was to assess the present evidence for therapeutic role of fluvoxamine in COVID-19 patients, the review included studies which evaluate the effect of fluvoxamine in COVID-19 patients. The main outcomes evaluated in the review were: mortality, need for hospitalization (outpatients) and clinical deterioration. The quality control of the selected articles was made using Cochrane’s Risk of Bias tool for the randomized controlled trials (RCTs) and the ROBINS-I criteria for non-randomized studies. A total of 4 studies were included in the final qualitative analysis of the review, 2 of which were RCTs, and the others were open-label prospective cohorts. 3 studies assessed outpatient population and 1 evaluated ICU population. Overall, the 4 studies included a total of 1864 participants. In conclusion, 3 studies with outpatients showed that fluvoxamine treatment can prevent clinical deterioration, hospitalisation, or proxy-hospitalisation. The only study with patients hospitalized in the ICU also demonstrated a therapeutic benefit reducing overall mortality.

Length of anticoagulation for thrombotic events related to COVID-19 is unknown. We present a patient with COVID-19 complicated by a thrombotic anterior STEMI and multiple left ventricular (LV) thrombi that resolved after 8 weeks of anticoagulation. We suggest a shorter length of anticoagulation with COVID-19 related LV thrombus.

Background: Although avian coronavirus infectious bronchitis virus (IBV) and SARS-CoV-2 belong to different genera of the Coronaviridae family, exposure to IBV may result in the development of cross-reactive antibodies to SARS-CoV-2 due to homologous epitopes. We aimed to investigate whether antibody responses to IBV cross-react with SARS-CoV-2 in poultry farm personnel who are occupationally exposed to aerosolized IBV vaccines. Methods: We analyzed sera from poultry farm personnel, COVID-19 patients, and pre-pandemic controls. IgG levels against the SARS-CoV-2 antigens S1, RBD, S2, and N and peptides corresponding to the SARS-CoV-2 ORF3a, N, and S proteins as well as whole virus antigens of the four major S1-genotypes 4/91, IS/1494/06, M41, and D274 of IBV were investigated by in-house ELISAs. Moreover, live-virus neutralization test (VNT) was performed. Results: A subgroup of poultry farm personnel showed elevated levels of specific IgG for all tested SARS-CoV-2 antigens compared to pre-pandemic controls. Moreover, poultry farm personnel, COVID-19 patients, and pre-pandemic controls showed specific IgG antibodies against IBV strains. These antibody titers were higher in long-term vaccine implementers. We observed a strong correlation between IBV-specific IgG and SARS-CoV-2 S1-, RBD-, S2-, and N-specific IgG in poultry farm personnel compared to pre-pandemic controls and COVID-19 patients. However, no neutralization was observed for these cross-reactive antibodies from poultry farm personnel using the VNT. Conclusion: We report here for the first time the detection of cross-reactive IgG antibodies against SARS-CoV-2 antigens in humans exposed to IBV vaccines. These findings have implications for future vaccination strategies and possibly cross-reactive T cell immunity.

Although the presence of morphea following COVID-19 has been rarely reported, development of its generalized form following COVID-19 vaccination has not been reported yet. Here, we reported the first case of generalized morphea following COVID-19 vaccination and another similar case following SARS-Cov-2 infection. Other etiologic factors were also dealt with

COVID-19 related MIS-C (Multisystem inflammatory syndrome in children) can present with cardiovascular complications like shock, arrhythmias, pericardial effusion, and coronary artery dilatation. The majority of MIS-C associated coronary artery abnormalities are dilation or small aneurysms which are transient and resolve in a few weeks[[1, 2]](#ref-0001). We present here a case of a 3-month-old child who was noted to have giant aneurysms of her coronary arteries (LAD and RCA) twenty-six days after testing positive for COVID-19. She was treated with IVIG, infliximab, and glucocorticoids along with aspirin, clopidogrel and enoxaparin. She did not show any signs of coronary ischemia or cardiac dysfunction but continued to have persistent giant coronary artery aneurysms involving the LAD (z-score ~35) and RCA (z-score ~30) [Fig. 1]. This study emphasizes the importance of early detection and aggressive management of MIS-C to prevent potentially life-threatening consequences.

Aim: We aimed to examine fetal cardiac output (CO) in patients who recovered from severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Materials: This prospective study included 48 pregnant women recovered from SARS-CoV-2 infection and 50 control cases. SARS-CoV-2 infection was diagnosed by polymerase chain reaction (PCR) test in patients. Fetal echocardiographic evaluations were performed at 24-37 weeks of gestation in pregnant women who recovered from the infection and control group. Results: The median value of ultrasound evaluation was 34 (2.6) weeks of gestation in the recovery from the SARS-CoV-2 infection (RSI) group, and 32 (7.6) weeks in the control group (p=0.565). Left cardiac output (LCO) z score was significantly lower in the RSI group than the control group (p=0,041). LCO and combine cardiac output (CCO) z score were significantly lower in the severe disease group than mild, moderate disease groups, and controls (p=0,019 and p=0,013). CCO (mL/min/kg) was decreased in the severe disease group when compared with control and mild disease groups (p=0,044). Fetal distress, preterm delivery rate, and neonatal intensive care unit (NICU) admission were found to be higher in the severe disease group compared to the control group (p=0,010, p=0,009, and p<0,001 respectively). Conclusion: In the present study, fetal cardiac output in pregnant women with recovery from SARS-CoV-2 infection was found significantly decreased, especially in whom had severe diseases. Placental dysfunction and inflammatory cytokines might cause fetal cardiac changes. Further studies could be clarified on the impact of SARS-CoV-2 infection on fetal cardiac function.

Autopsy was performed on a COVID-19 patient, who suddenly died despite the extensive anti-viral and anti-inflammatory therapies. Although moderate subpleural fibrosis was seen, pathology of DAD, a well-known cause for pulmonary failure, was minimum. Instead, severe hemorrhage was observed. Therapeutic effects were indicated, however why severe hemorrhage occurred was unclear.
