Mortality from gastrointestinal congenital anomalies at 264 hospitals in 74 low-income, middle-income, and high-income countries: a multicentre, international, prospective cohort study

Summary Background Congenital anomalies are the fifth leading cause of mortality in children younger than 5 years globally. Many gastrointestinal congenital anomalies are fatal without timely access to neonatal surgical care, but few studies have been done on these conditions in low-income and middle-income countries (LMICs). We compared outcomes of the seven most common gastrointestinal congenital anomalies in low-income, middle-income, and high-income countries globally, and identified factors associated with mortality. Methods We did a multicentre, international prospective cohort study of patients younger than 16 years, presenting to hospital for the first time with oesophageal atresia, congenital diaphragmatic hernia, intestinal atresia, gastroschisis, exomphalos, anorectal malformation, and Hirschsprung’s disease. Recruitment was of consecutive patients for a minimum of 1 month between October, 2018, and April, 2019. We collected data on patient demographics, clinical status, interventions, and outcomes using the REDCap platform. Patients were followed up for 30 days after primary intervention, or 30 days after admission if they did not receive an intervention. The primary outcome was all-cause, in-hospital mortality for all conditions combined and each condition individually, stratified by country income status. We did a complete case analysis. Findings We included 3849 patients with 3975 study conditions (560 with oesophageal atresia, 448 with congenital diaphragmatic hernia, 681 with intestinal atresia, 453 with gastroschisis, 325 with exomphalos, 991 with anorectal malformation, and 517 with Hirschsprung’s disease) from 264 hospitals (89 in high-income countries, 166 in middleincome countries, and nine in low-income countries) in 74 countries. Of the 3849 patients, 2231 (58·0%) were male. Median gestational age at birth was 38 weeks (IQR 36–39) and median bodyweight at presentation was 2·8 kg (2·3–3·3). Mortality among all patients was 37 (39·8%) of 93 in low-income countries, 583 (20·4%) of 2860 in middle-income countries, and 50 (5·6%) of 896 in high-income countries (p<0·0001 between all country income groups). Gastroschisis had the greatest difference in mortality between country income strata (nine [90·0%] of ten in lowincome countries, 97 [31·9%] of 304 in middle-income countries, and two [1·4%] of 139 in high-income countries; p≤0·0001 between all country income groups). Factors significantly associated with higher mortality for all patients combined included country income status (low-income vs high-income countries, risk ratio 2·78 [95% CI 1·88–4·11], p<0·0001; middle-income vs high-income countries, 2·11 [1·59–2·79], p<0·0001), sepsis at presentation (1·20 [1·04–1·40], p=0·016), higher American Society of Anesthesiologists (ASA) score at primary intervention (ASA 4–5 vs ASA 1–2, 1·82 [1·40–2·35], p<0·0001; ASA 3 vs ASA 1–2, 1·58, [1·30–1·92], p<0·0001]), surgical safety checklist not used (1·39 [1·02–1·90], p=0·035), and ventilation or parenteral nutrition unavailable when needed (ventilation 1·96, [1·41–2·71], p=0·0001; parenteral nutrition 1·35, [1·05–1·74], p=0·018). Administration of parenteral nutrition (0·61, [0·47–0·79], p=0·0002) and use of a peripherally inserted central catheter (0·65 [0·50–0·86], p=0·0024) or percutaneous central line (0·69 [0·48–1·00], p=0·049) were associated with lower mortality. Interpretation Unacceptable differences in mortality exist for gastrointestinal congenital anomalies between lowincome, middle-income, and high-income countries. Improving access to quality neonatal surgical care in LMICs will be vital to achieve Sustainable Development Goal 3.2 of ending preventable deaths in neonates and children younger than 5 years by 2030

Spontaneous Coronary Artery Dissection: Chest Pain in a Young Woman.

We present two cases of spontaneous coronary artery dissection (SCAD). Both examples encourage a broad differential and open mind for chest pain in a young woman. We also highlight a case of SCAD where the patient presented following ventricular fibrillation arrest, a less common though potentially fatal consequence of SCAD

Sex differences in atrial fibrillation ablation in-hospital outcomes from the National Inpatient Sample database 2016–2019

Background: Research has shown mixed results when comparing in-hospital complications following atrial fibrillation ablation in women compared to men. Objectives: To better quantify sex differences and in-hospital outcomes in atrial fibrillation ablation procedures and identify factors associated with poorer outcomes. Methods: We queried the NIS database from 2016 to 2019 for hospitalizations with a primary diagnosis of atrial fibrillation ablation and excluded patients with any other arrhythmias, ICD/pacemaker placement. We assessed demographics, in-hospital mortality, and complications of women compared to men. Results: Admissions for atrial fibrillation were more common in females than males (849 050 vs. 815 665; p \u3c.001). However, females were less likely to receive ablation (1.65% vs. 2.71%, OR: 0.60; 95% confidence interval: 0.57–0.64, p \u3c.001), which persisted after adjusting for cardiomyopathy (adjusted OR: 0.61; 95% confidence interval: 0.58–0.65, p \u3c.001). The primary outcome of in-hospital mortality was not statistically different in univariate analysis (0.39% vs. 0.36%, OR: 1.09, 95% CI: 0.44–2.72, p =.84), finding that did not change when adjusted for comorbidities (adjusted OR: 0.94, 95% CI: 0.36–2.49). The complication rate in hospitalized patients following ablation was 8.08%. The total unadjusted complication rate was higher for females than males (9.58% vs. 7.09%, p =.001); however, it was not significant when adjusted for risks (adjusted OR: 1.23, 95% CI: 0.99–1.53, p =.06). Conclusion: Female sex is not associated with increased complications or death in a real-world study of catheter ablation when results are adjusted for risks. However, females admitted with atrial fibrillation receive ablation less often than males during hospital admission

National Yearly Trend of Utilization and Procedural Complication of the Watchman Device in the United States.

Background Complication from the Watchman device (Boston Scientific Corp, Marlborough, Massachusetts) is operator-dependent, with the latest EWOLUTION trial showing low complication rates (1.8%) thought to be due to maturing physician experience. Objectives The objective of this study is to understand the yearly trend of utilization and complication rates of the Watchman device in hospitalized patients. Methods The national inpatient sample (NIS) was queried for all hospitalization with primary atrial fibrillation or flutter from 2016 to 2019 with percutaneous left atrial appendage occlusion (LAAO). The frequency of peri-procedural complications, including death, stroke, major bleeding requiring blood transfusion, pericardial effusion, post-op hypotension, cardiac arrest, postprocedural CHF, implant displacement/leak, systemic embolism, and requiring repeat procedures, were assessed. Results From 2016 to 2019, an estimated 60,350 LAAO procedures were performed. The majority of the procedure was done in white (84.88%), males (58.40%), with a mean age of 76, at teaching hospitals (88.27%). Complication rates were around 5.72%, with no change from 2016 to 2019 (annual percentage change, APC: 6.23; p-value: 0.170) despite rapid increase in yearly utilization of Watchman from 1.12% in 2016 to 5.45% in 2019 (APC: 62.30; p-value of 0.013). Pericardial effusion (3.41%) was the most common complication, followed by bleeding requiring transfusion (1.40%) that had no significant change over time. Conclusion Our study demonstrates that trend of complications with the Watchman device implantation in the real-world practice didn\u27t improve over time, possibly due to characteristics inherent to the device and patient population. Hence, we expect a further drop in nationwide complication rates with the improved design of Watchman-FLX and increased placement experience

Sex differences in atrial fibrillation ablation in‐hospital outcomes from the National Inpatient Sample database 2016–2019

Abstract Background Research has shown mixed results when comparing in‐hospital complications following atrial fibrillation ablation in women compared to men. Objectives To better quantify sex differences and in‐hospital outcomes in atrial fibrillation ablation procedures and identify factors associated with poorer outcomes. Methods We queried the NIS database from 2016 to 2019 for hospitalizations with a primary diagnosis of atrial fibrillation ablation and excluded patients with any other arrhythmias, ICD/pacemaker placement. We assessed demographics, in‐hospital mortality, and complications of women compared to men. Results Admissions for atrial fibrillation were more common in females than males (849 050 vs. 815 665; p < .001). However, females were less likely to receive ablation (1.65% vs. 2.71%, OR: 0.60; 95% confidence interval: 0.57–0.64, p < .001), which persisted after adjusting for cardiomyopathy (adjusted OR: 0.61; 95% confidence interval: 0.58–0.65, p < .001). The primary outcome of in‐hospital mortality was not statistically different in univariate analysis (0.39% vs. 0.36%, OR: 1.09, 95% CI: 0.44–2.72, p = .84), finding that did not change when adjusted for comorbidities (adjusted OR: 0.94, 95% CI: 0.36–2.49). The complication rate in hospitalized patients following ablation was 8.08%. The total unadjusted complication rate was higher for females than males (9.58% vs. 7.09%, p = .001); however, it was not significant when adjusted for risks (adjusted OR: 1.23, 95% CI: 0.99–1.53, p = .06). Conclusion Female sex is not associated with increased complications or death in a real‐world study of catheter ablation when results are adjusted for risks. However, females admitted with atrial fibrillation receive ablation less often than males during hospital admission
