Abstract Background In 2011, the World Health Organization recommended injectable artesunate as the first-line therapy for severe malaria (SM) due to its superiority in reducing mortality compared to quinine. There are limited data on long-term clinical and neurobehavioral outcomes after artemisinin use for treatment of SM. Methods From 2008 to 2013, 502 Ugandan children with two common forms of SM, cerebral malaria and severe malarial anemia, were enrolled in a prospective observational study assessing long-term neurobehavioral and cognitive outcomes following SM. Children were evaluated a week after hospital discharge, and 6, 12, and 24 months of follow-up, and returned to hospital for any illness. In this study, we evaluated the impact of artemisinin derivatives on survival, post-discharge hospital readmission or death, and neurocognitive and behavioral outcomes over 2 years of follow-up. Results 346 children received quinine and 156 received parenteral artemisinin therapy (artemether or artesunate). After adjustment for disease severity, artemisinin derivatives were associated with a 78% reduction in in-hospital mortality (adjusted odds ratio, 0.22; 95% CI, 0.07–0.67). Among cerebral malaria survivors, children treated with artemisinin derivatives also had reduced neurologic deficits at discharge (quinine, 41.7%; artemisinin derivatives, 23.7%, p=0.007). Over a 2-year follow-up, artemisinin derivatives as compared to quinine were associated with better adjusted scores (negative scores better) in internalizing behavior and executive function in children irrespective of the age at severe malaria episode. After adjusting for multiple comparisons, artemisinin derivatives were associated with better adjusted scores in behavior and executive function in children <6 years of age at severe malaria exposure following adjustment for child age, sex, socioeconomic status, enrichment in the home environment, and the incidence of hospitalizations over follow-up. Children receiving artesunate had the greatest reduction in mortality and benefit in behavioral outcomes and had reduced inflammation at 1-month follow-up compared to children treated with quinine. Conclusions Treatment of severe malaria with artemisinin derivatives, particularly artesunate, results in reduced in-hospital mortality and neurologic deficits in children of all ages, reduced inflammation following recovery, and better long-term behavioral outcomes. These findings suggest artesunate has long-term beneficial effects in children surviving severe malaria.

Aortic Arch Hypoplasia

The problem of the effectiveness of obstruction at the level of the aortic arch is still a matter of discus-sion in the modern literature. Traditionally, by excision of the coarctation part, in the presence of hypoplasia, the incision is extended to a narrowed area and a modification of the classical end-to-end anastomosis is applied in the form of an elongated or expanded variant. Recently, when proximal part is involved in the pathological process, cardiac surgeons have been more likely to use median sternotomy using other types of plastic surgery, including dilation of the narrowed area with a pericardial patch, or pulmonary artery tissue. Accordingly, the analysis of the results of the use of end-to-end anastomosis in young children with aortic arch hypoplasia, especially in view of long-term survival and the level of reoperation, is an important issue of neonatal cardiac surgery. The aim. To evaluate the effectiveness of the use of an extended end-to-end anastomosis after reconstruction of the aortic arch in children under 1 year of age. Materials and methods. The study material included 348 infants who underwent surgical correction of aortic arch hypoplasia through the method of extended end-to-end anastomosis from 2010 to 2020. The operations were performed at the National Amosov Institute of Cardiovascular Surgery of the NAMS of Ukraine and the Ukrainian Children’s Cardiac Center. The study group included only patients with two-ventricular physiology. There were 233 male patients (67%) and 115 female patients (33%). The mean age was 1.07 (0.20; 2.30) months, the mean weight was 3.89 (3.30; 4.90) kg, the mean body surface area was 0.23 (0.20; 0.28) m2. Diagnosis of aortic arch hypoplasia was based on two-dimensional echocardiography. Results. According to echocardiography, after surgery there was a significant decrease in the pressure gradient in the aortic arch from 48.3 ± 20.3 to 16 ± 6.9 (p<0.05), left ventricular PV increased significantly from 61.6 ± 12% to 66.3 ± 6.4% (p> 0.05). The hospital mortality was 1.7% (n = 6). The causes of mortality were not related to the end-to-end aortic arch technique. The duration of follow-up period ranged from 1 month to 9.3 years. Two deaths occurred in the follow-up period. Thirty-two (9.1%) patients developed aortic arch restenosis in the postoperative period. Balloon dilatation of restenosis was performed in 21 patients. Eleven patients underwent repeated aortic arch repair surgery through the median sternotomy. There were no central nervous system complications in the follow-up period. Conclusions. The use of an extended end-to-end anastomosis in the surgical treatment of aortic arch hypoplasia demon strates low hospital mortality and high long-term survival. Indications for the effective use of this type of reconstruction are hypoplasia of the isthmus and distal aortic arch.

Purpose To examine associations among methotrexate pharmacodynamics, neuroimaging, and neurocognitive outcomes in long-term survivors of childhood acute lymphoblastic leukemia treated on a contemporary chemotherapy-only protocol. Patients and Methods This longitudinal study linked pharmacokinetic assays collected during therapy to neurocognitive and brain imaging outcomes during long-term follow-up. A total of 218 (72.2%) of 302 eligible long-term survivors were recruited for outcome studies when they were more than 5 years post-diagnosis and older than 8 years of age. At long-term follow-up, survivors were an average of 13.8 years old and 7.7 years from diagnosis, and 51% were male. Neurocognitive testing, functional magnetic resonance imaging (MRI) during an executive function task, and structural MRI with diffusion tensor imaging were conducted. Generalized linear models were developed to identify predictors, and models were adjusted for age at diagnosis, sex, and parent education. Results Intelligence was within normal limits (mean, 98; standard deviation, 14) compared with population expectations (mean, 100; standard deviation, 15), though measures of executive function, processing speed, and memory were less than population means (all P < .02 after correction for false discovery rates). Higher plasma concentration of methotrexate was associated with a poorer executive function score (P < .02). Higher plasma methotrexate was also associated with higher functional MRI activity, with thicker cortices in dorsolateral prefrontal brain regions, and with white matter microstructure in the frontostriatal tact. Neurocognitive impairment was associated with these imaging findings as well. Associations did not change after adjustment for age or dose of leucovorin rescue. Conclusion Survivors of childhood acute lymphoblastic leukemia treated on contemporary chemotherapy-only protocols demonstrate executive dysfunction. A higher plasma concentration of methotrexate was associated with executive dysfunction as well as with a thicker cortex and higher activity in frontal brain regions, regions often associated with executive function.

ObjectiveTakotsubo syndrome (TS) mimics acute coronary syndrome (ACS) but has a distinct pathophysiology. While in-hospital adverse outcomes appear similar to those presenting with an ACS, data on longer term postdischarge risk are conflicting. This study sought to assess the long-term prognosis of patients discharged alive after TS.MethodsThe clinical profile and in-hospital and long-term outcomes were prospectively assessed in consecutive patients with TS. Survival in patients with TS was compared with two representative age-matched and gender-matched comparison cohorts: a hospitalised ACS cohort and a community cohort without known cardiovascular disease (CVD).ResultsTwo hundred and-twenty-five patients with TS (216 women, mean age 63.7±11.8 years) were included. In-hospital mortality was 1.8% and 1.9% for patients with TS and ACS, respectively. Of the 219 patients with TS with postdischarge follow-up, at a mean follow-up of 4.8±3.2 years, there were 19 (8.3%) deaths, 18 of which were from non-cardiac causes. When compared with the cohort without prior CVD, postdischarge patients with TS were at increased mortality risk (HR 2.00, 95% CI 1.26 to 3.17, p=0.003), but mortality in postdischarge patients with ACS was over threefold higher (HR 3.43, 95% CI 2.97 to 3.96, p<0.0001).ConclusionsIn-hospital mortality for patients diagnosed with TS and ACS was similar. However, while postdischarge survivors of TS had a long-term survival which was poorer than for a community-based cohort without known CVD, their survival was better than for postdischarge survivors of an ACS event. Late deaths in patients with TS were almost all from non-cardiac causes.

Abstract Background and Aims Acute Kidney Injury (AKI) is an important determinant of outcome in hospitalized patients. Further, there is a risk for development of Chronic Kidney Disease (CKD) in the future. Though the long-term impact of AKI has been studied in developed countries, there is a paucity of data in this area from the Indian subcontinent. This single-centre study aimed to assess the pattern, clinical spectrum, short-term and long-term outcomes of AKI. Method In this prospective observational cohort study, detailed demographic and clinical data at presentation, during hospital stay and follow-up at 1, 3, 6 and 12 months after discharge were obtained prospectively for a cohort of patients with AKI. Both community (CAAKI) and hospital acquired AKI (HAAKI) were included. Patient with pre-existing CKD were excluded. Outcome variables examined were in-hospital mortality, renal function at discharge and on follow-up after discharge from hospital. Results In our study cohort with 476 patients, majority of the cases were CAAKI (395, 83%). The mean age at presentation was 44.8 ± 18.7 years. Medical causes (84%) contributed to the majority of AKI while the remaining were due to surgical (10%) and obstetrical (6%) causes. Sepsis (176/476; 36.9%) was the most common cause of AKI. The most common source for sepsis was respiratory (41%) followed by urological source (18.7%). The in-hospital mortality rate for patients with AKI was 38%. Age &gt;60 years (HR = 1.51; 95% CI, 1.11 – 2.07), oliguria (HR = 1.48; 95% CI, 1.05 – 2.10), need for ventilator (HR = 2.45; 95% CI, 1.36 – 4.41) and/or inotropes (HR = 14.4; 95% CI, 6.28 – 33.05) were predictors of mortality. At discharge, 146 (30.7%) patients had complete renal recovery, while 149 (31.3%) had partial renal recovery. Oliguria (p &lt; 0.001), hypoalbuminemia (p = 0.001) and need for renal replacement therapy (RRT) (p = 0.01) were significantly associated with partial recovery. Of the 295 patients on follow-up at discharge, 211 (71.5%) patients had normal renal function, 4 (1.4%) died and 33 (11.2%) were lost to follow up; 47(15.9%) patients developed CKD of which 6 (2%) were dialysis dependent. Elderly patients, higher AKIN stage with oliguria and those requiring RRT were more likely to develop CKD. Among these, the need for in-hospital RRT was the single most important factor predicting the risk of CKD (OR 1.77, 95% CI, 1.12-2.78). Conclusion In conclusion, our data shows that AKI in hospitalized patients still has high mortality in emerging countries like India. Though a fairly good percentage of cases recovered, there is a definite risk of CKD development, especially in patients who required RRT during hospitalization.

Main funding source(s): Beca para la Formación e Investigación en Cuidados Críticos Cardiológicos concedida por la Asociación de Cardiopatía Isquémica y Cuidados Críticos Cardiológicosde la SEC Introduction Available data on arrhythmic storm (AS) is usually obtained from retrospective observational studies based on series of patients (pts) with ICD or who undergo ablation. Therefore, selection bias limits the evidence regarding mortality and prognosis of this entity. Purpose/ Methods Describe in-hospital and long-term mortality of pts admitted between 2006 and 2020 for AS in the Acute Cardiac Care Unit (ACCU) of 2 tertiary hospitals in Spain. Results A total of 190 episodes of AS in 169 pts were retrospectively analysed. Baseline characteristics are depicted in Table 1. In-hospital mortality was 18.9%. Mortality in STEMI related AS was 44.2%, while in the rest of aetiologies was 6.1% (p &lt; 0.001). In-hospital cause of death was heart failure or cardiogenic shock (32.4%), refractory AS (20.6%), cardiac arrest due to pulseless activity (8.8%), severe postanoxic encephalopathy (14.7%), septic shock (8.8%), others (14.7%). long-term follow-up was obtained in 154 pts. Among those patients who survived after the first episode of AS, median follow up was 2.85 years. Long term mortality was 49.7%. Long-term survival did not differ among STEMI related AS (8.30 years, 95% CI 5.62 to 10.98) and the rest of aetiologies (6.91 years, 95% CI 5.75 to 8.07), Log rank 0.33. Kapplan-Meier survival curves are presented in Figure 1. Long-term cause of death was AS (8.3%), heart failure or cardiogenic shock (14.6%), cardiac arrest due to pulseless activity (4.2%), STEMI (2.1%), stroke (8.3%), cancer (10.4%), pneumonia and sepsis (22.9%) and unknown (29.2%). Conclusion In-hospital mortality in patients with AS requiring admission to an ACCU differs depending on the aetiology being worst in STEMI related AS. Long term mortality remains high and do not depend on the ethiology.

AbstractInfective endocarditis represents a surgical challenge associated with perioperative mortality. The aim of this study is to evaluate the predictors of operative mortality and long-term outcomes in high-risk patients. We retrospectively analyzed 123 patients operated on for infective endocarditis from January 2011 to December 2020. Logistic regression model was used to identify prognostic factors of in-hospital mortality. Long term follow-up was made to asses late prognosis. Preoperative renal failure, an elevation EuroSCORE II and prior aortic valve re-replacement were found to be preoperative risk factors significantly associated with mortality. In-hospital mortality was 27% in patients who had previously undergone aortic valve replacement (n = 4 out of 15 operated, p = 0.01). Patients who were operated on during the active phase of infective endocarditis showed a higher mortality rate than those operated on after the acute phase (16% vs. 0%; p = 0.02). The type of prosthesis used (biological or mechanical) was not associated with mortality, whereas cross-clamp time significantly correlated with mortality (mean cross-clamp time 135 ± 65 min in dead patients vs. 76 ± 32 min in surviving patients; p = 0.0005). Mean follow up was 57.94 ± 30.9 months. Twelve patients died (11.65%). Among the twelve mortalities, five were adjudicated to cardiac causes and seven were non-cardiac (two cancers, one traumatic accident, one cerebral hemorrhage, two bronchopneumonia, one peritonitis). Overall survival probability (freedom from death, all causes) at 3, 5, 7 and 8 years was 98.9% (95% CI 97–100%), 96% (95% CI 92–100%), 85.9% (95% CI 76–97%), and 74% (95% CI 60–91%) respectively. Our study demonstrates that an early surgical approach may represent a valuable treatment option for high-risk patients with infective endocarditis, also in case of prosthetic valve endocarditis. Although several risk factors are associated with higher mortality, no patient subset is inoperable. These findings can be helpful to inform decision-making in heart team discussion.
