Development of a validated novel bead extraction method for the detection of anti-PEG antibodies in human serum.

Aims: Polyethylene glycol (PEG) is used in many applications including drug development. Due to exposure to environmental products, there is a high prevalence of preexisting anti-PEG antibodies in the global human population. The presence of anti-PEG antibodies is a concern for potentially reducing the efficacy of therapeutics after administration and represents a risk of safety events after exposure to PEGylated drug products.

Optimal Approaches for Pregnant Patients Undergoing Percutaneous Coronary Intervention.

Cardiovascular disease is the leading cause of maternal mortality in the United States. Pregnancy is associated with increased risk of acute myocardial infarction (AMI) and outcomes of pregnancy-associated AMI (PAMI) are poor. Spontaneous coronary artery dissection is the most common cause of PAMI.

Obstetric anesthesia management of dilated cardiomyopathies and heart failure: a narrative review.

Pregnancy in patients with dilated cardiomyopathy carries a significantly increased risk of maternal mortality or severe morbidity, and pregnancy is typically considered contraindicated for patients with severely reduced ventricular function. Nonetheless, anesthesiologists will still encounter patients with cardiomyopathy requiring delivery or termination care. This review describes how NT-ProBNP testing and echocardiography can help with early recognition of heart failure in pregnancy, and describes a suggested approach to anesthetic management of patients with cardiomyopathies or acute heart failure, including hemodynamic goals, use of vasoactive medications and mechanical support.

Decreased postpartum exercise capacity after a diagnosis of pre-eclampsia: Implications for CVD risk prediction.

Background: Hypertensive disorders of pregnancy (HDP) are associated with increased long-term risk for cardiometabolic risk factors (chronic hypertension [HTN], obesity, diabetes) and heart failure. Exercise capacity is a known predictor of heart failure in patients with normal resting cardiac filling pressures. In this prospective observational cohort study, we sought to identify predictors of reduced postpartum exercise capacity in participants with normotensive vs preeclamptic pregnancies.

Migraine headache in patients with spontaneous coronary artery dissection: A report of the iSCAD Registry.

Introduction: Spontaneous coronary artery dissection (SCAD) is a nonatherosclerotic cause of myocardial infarction. Migraine headache has been reported to be common among patients with SCAD, but the degree of migraine-related disability has not been quantified.

Methods: Clinical data and headache variables were obtained from the baseline assessment of the prospective, multicenter iSCAD Registry.

Acute Coronary Syndrome in Women: An Update.

Purpose Of Review: The goal of this manuscript is to provide a concise summary of recent developments in the approach to and treatment of women with acute coronary syndrome (ACS).

Recent Findings: This review covers terminology updates relating to ACS and myocardial injury and infarction. Updates on disparities in recognition, treatments, and outcomes of women with ACS due to atherosclerotic coronary artery disease are covered.

Radiopaque marker colonic transit study in the pediatric population BSPGHAN Motility Working Group consensus statement.

Functional constipation (FC) is a common condition in childhood in the United Kingdom and worldwide. Various radiological approaches have been established for diagnostic purposes. The radiopaque marker study (ROMS) is universally accepted and used to assess colonic transit time (CTT) in children with FC.

The role of high-resolution impedance manometry to identify rumination syndrome in children with unexplained foregut symptoms.

Objectives: Diagnosis of rumination syndrome (RS) relies on Rome IV criteria. Oesophageal high-resolution impedance manometry (HRIM) can objectively demonstrate the episodes of rumination, but its role in the diagnostic pathway is not yet established. We aimed to demonstrate the clinical contribution of this tool for the timely diagnosis of RS and diagnostic work-up of children with unexplained foregut symptoms deemed to be due to other conditions.

Differences in Cardiometabolic Proteins in Pregnancy Prioritize Relevant Targets of Preeclampsia.

Background: Preeclampsia is a hypertensive disorder of pregnancy characterized by widespread vascular inflammation. It occurs frequently in pregnancy, often without known risk factors, and has high rates of maternal and fetal morbidity and mortality. Identification of biomarkers that predict preeclampsia and its cardiovascular sequelae before clinical onset, or even before pregnancy, is a critical unmet need for the prevention of adverse pregnancy outcomes.

Treatment of Severe Symptomatic Aortic Stenosis During Pregnancy: A Potential Role for TAVR?

A 35-year-old woman presented at 22 weeks gestation with severe symptomatic aortic stenosis with a mean gradient of 94 mm Hg and an aortic valve area of 0.53 cm. After multidisciplinary discussion, she underwent transcatheter aortic valve replacement during pregnancy.

Cardiovascular Fellowship Training in Cardio-Obstetrics: JACC Review Topic of the Week.

The United States has the highest maternal mortality in the developed world with cardiovascular disease as the leading cause of pregnancy-related deaths. In response to this, the emerging subspecialty of cardio-obstetrics has been growing over the past decade. Cardiologists with training and expertise in caring for patients with cardiovascular disease in pregnancy are essential to provide effective, comprehensive, multidisciplinary, and high-quality care for this vulnerable population.

Sex Differences in Thoracic Aortic Disease and Dissection: JACC Review Topic of the Week.

Despite its higher prevalence among men, women with thoracic aortic aneurysm and dissection (TAAD) have lower rates of treatment and surgical intervention and often have worse outcomes. A growing number of women with TAAD also desire pregnancy, which can be associated with an increased risk of aortic complications. Understanding sex-specific differences in TAAD has the potential to improve care delivery, reduce disparities in treatment, and optimize outcomes for women with TAAD.

Small Bowel Transit Scintigraphy in Children With Pediatric Intestinal Pseudo-Obstruction.

Introduction: Objective evidence of small intestinal dysmotility is a key criterion for the diagnosis of pediatric intestinal pseudo-obstruction (PIPO). Small bowel scintigraphy (SBS) allows for objective measurement of small bowel transit (SBT), but limited data are available in children. We aimed to evaluate the utility of SBS in children suspected of gastrointestinal dysmotility.

Pregnancy as an Early Cardiovascular Moment: Peripartum Cardiovascular Health.

Pregnancy is commonly referred to as a window into future CVH (cardiovascular health). During pregnancy, physiological adaptations occur to promote the optimal growth and development of the fetus. However, in approximately 20% of pregnant individuals, these perturbations result in cardiovascular and metabolic complications, which include hypertensive disorders of pregnancy, gestational diabetes, preterm birth, and small-for-gestational age infant.
