In SARS-CoV-2 patients with severe acute respiratory distress syndrome (ARDS), Veno-Venous Extracorporeal Membrane Oxygenation (V-V ECMO) was shown to provide valuable treatment with reasonable survival in large multi-centre investigations. However, in some patients, conversion to modified ECMO support forms may be needed. In this single-centre retrospective registry, all consecutive patients receiving V-V ECMO between 1 March 2020 to 1 May 2021 were included and analysed. The patient cohort was divided into two groups: those who remained on V-V ECMO and those who required conversion to other modalities. Seventy-eight patients were included, with fourteen cases (18%) requiring conversions to veno-arterial (V-A) or hybrid ECMO. The reasons for the ECMO mode configuration change were inadequate drainage (35.7%), inadequate perfusion (14.3%), myocardial infarction (7.1%), hypovolemic shock (14.3%), cardiogenic shock (14.3%) and septic shock (7.1%). In multivariable analysis, the use of dobutamine (p = 0.007) and a shorter ICU duration (p = 0.047) predicted the conversion. The 30-day mortality was higher in converted patients (log-rank p = 0.029). Overall, only 19 patients (24.4%) survived to discharge or lung transplantation. Adverse events were more common after conversion and included renal, cardiovascular and ECMO-circuit complications. Conversion itself was not associated with mortality in the multivariable analysis. In conclusion, as many as 18% of patients undergoing V-V ECMO for COVID-19 ARDS may require conversion to advanced ECMO support.

AimsDurability of transcatheter aortic valve implantation (TAVI) is key to its expansion. We sought to identify incidence of valve thrombosis and predictors of valve thrombosis in our single centre with associated coagulation testing pre-TAVI and post-TAVI.Methods and resultsThis single-centre observational study comprised patients undergoing transfemoral TAVI discussed in the Heart Team meeting . Patients were followed up with echocardiography at 120 days to identify incidence of elevated transvalvular gradient and multivariable analysis was performed to identify factors associated with an increased odds of developing valve thrombosis. In addition, 11 patients underwent baseline, day 1 and day 120 post-TAVI coagulation testing. Between August 2017 and August 2019, 437 consecutive patients underwent transfemoral TAVI. Of these patients, 207/437 (47.4%) had 3-month follow-up echo data available and were analysed. Of these patients, 26/207 (12.6%) had elevated transvalvular gradients. These patients tended to be younger (80±14 vs 83±6 years; p=0.047) with a lower ejection fraction (49±13 vs 54%±11%; p=0.021), with a greater proportion of the population experiencing atrial fibrillation (14/21, 54% vs 68/181, 38%; p=0.067). Following multivariable analysis, there remained a trend towards higher eccentricity index associated with elevated gradients. Baseline (pre-TAVI) elevation of thrombin antithrombin levels (56±63; reference range 1.0–4.1 ng/L) and PF 1+2 (791±632; reference range 69–229 ng/mL) normalised at 120 days post-TAVIConclusionThis study demonstrated that in the cohort of patients undergoing transfemoral TAVI in our centre: younger age, poor ejection fraction, atrial fibrillation and increased baseline eccentricity of the aortic valve annulus were present to a greater extent in patients exhibiting elevated transvalvular gradients at 3-month follow-up. Further work is required to delineate the extent of coagulation derangement and confirm predictors of thrombosis.

In ST segment elevation acute myocardial infarction (STEMI), the endothelin (ET) system imbalance, reflected by the circulating ET-1:ET-3 ratio has not been investigated. This study’s primary objective was to measure the circulating ET-1:ET-3 ratio and correlate it with the risk stratification for 1 year mortality of STEMI based on TIMI score. On admission, the TIMI risk score and at discharge, the dynamic TIMI risk score were calculated in 68 consecutive subjects with STEMI. Subjects with high TIMI risk score were associated with higher mean ET-1 level and ET-1:ET-3 ratio. The ET-1:ET-3 ratio more accurately predicted the high on admission TIMI risk score than the ET-1 level. Subjects with high dynamic TIMI risk score were associated with higher mean ET-1 level and ET-1:ET-3 ratio. The ET-1:ET-3 ratio more accurately predicted the high at discharge dynamic TIMI risk score than ET-1 level. From multivariable analysis, the ET-1:ET-3 ratio was not independently associated with high on admission TIMI risk score but independently predicted high at discharge dynamic TIMI risk score (odds ratio = 9.186, p = 0.018). In conclusion, combining the ET-1 and ET-3 levels into the ET-1:ET-3 ratio provided a prognostic value by independently predicting the increased risk to 1 year mortality as indicated by at discharge dynamic TIMI risk score in patients with STEMI.

We herein report three cases of group A Streptococcus (GAS) infection in a family. Patient 1, a 50-year-old woman, was transferred to our hospital in shock with acute respiratory distress syndrome, swelling in the right neck and erythemata on both lower extremities. She required intubation because of laryngeal oedema. At the same time, patient 2, a 48-year-old man, was admitted because of septic shock, pneumonia and a pulmonary abscess. Five days later, patient 3, a 91-year-old woman, visited our clinic with bloody stool. All three patients were cured by antibiotics, and GAS was detected by specimen cultures. During these patients’ clinical course, an 84-year-old woman was found dead at home after having been diagnosed with type A influenza. All four patients lived in the same apartment. The GAS genotypes detected in the first three patients were identical. When treating patients with GAS, appropriate management of close contacts is mandatory.

Background: Shock is a state of impaired tissue perfusion resulting in an imbalance between oxygen demand and supply. This widespread reduction in effective tissue perfusion causes insufficient or improper delivery and distribution of oxygen and nutrients, the end result of which is an altered cellular and sub cellular function leading to anaerobic metabolism and accumulation of lactic acid, and consequently cellular damage, multiple organ dysfunction and finally cardiovascular collapse.Methods: The present study was conducted in the department of Pediatrics at Alluri Sitarama Raju Academy of Medical Sciences hospital, Eluru, between December 2014 and June 2016. It is a prospective study. Children aged 1 month to 12 years with a clinical diagnosis of shock were included after written consent from parents.Results: Out of 75 children admitted with shock, 69.33% had septic shock, 25.33% had hypovolemic shock, 2.66% had distributive shock, 2.66% cardiogenic shock. Most common age group admitted with shock was 1 month-1 year 38.666%. Among 75 children with shock, 74.66% children survived and 25.33% children died. Mortality rate in cardiogenic shock was 100%, in septic shock 28.84%, in hypovolemic shock 10.52%.Conclusions: Septic shock was the most common type of shock. Most common cause for septic shock was pneumonia. Septic shock has got highest mortality in the present study.Need for inotropes and mechanical ventilaton indicates poor prognosis in shock.
