Background: Chronic constipation is a common condition, and dyssynergic defecation underlies up to 40% of cases. Anorectal manometry is recommended to assess for dyssynergic defecation among chronically constipated patients but remains poorly standardized. We aimed to evaluate the diagnostic accuracy of anorectal manometry and determine optimal testing parameters. Methods:We performed a systematic review with meta-analysis of diagnostic test accuracy including cohort studies of chronically constipated patients and case-control studies of patients with dyssynergic defecation or healthy controls. Meta-analysis was performed to determine summary sensitivity, specificity, and area under the curve (AUC) with 95% confidence intervals (CI).
Purpose of Review The “fourth trimester” concept, defined as the first 12 weeks after delivery (and beyond), is a critical window of time for clinicians to intervene to optimize women’s cardiovascular health after pregnancy. A timely and comprehensive postpartum cardiovascular assessment should be performed in all women following delivery in order to (1) follow up medical conditions present prior to conception, (2) evaluate symptoms and signs of common postpartum complications, and (3) identify risk factors and prevent future adverse cardiovascular outcomes. In this review, we aim to discuss major maternal cardiovascular risk factors such as hypertensive disorders of pregnancy, gestational diabetes mellitus, postpartum weight retention, and postpartum depression, as well as lactation as a potential protective risk modifying factor. Additionally, we will review effectiveness of outpatient interventions to enhance transitions in cardiovascular care during the fourth trimester. Recent Findings A seamless hand-off from obstetric to primary care, and potentially cardiology, is needed for early detection and management of hypertension, weight, glycemic control, stress and mood, and long-term cardiovascular risk. Additionally, the use of telemedicine, blood pressure self-monitoring, remote activity monitoring, and behavioral health coaches are potentially feasible modalities to augment clinic-based care for cardiovascular risk factors and weight management, but additional studies are needed to study their long-term effectiveness. Summary Development of a comprehensive postpartum care plan with careful consideration of each patient’s risk profile and access to resources is critical to improve maternal morbidity and mortality, reduce health disparities, and achieve long-term cardiovascular health for women. Supporting postpartum well-being of women during this transition period requires a multidisciplinary approach, especially primary care engagement, and planning should start before delivery.
The incidence of arrhythmia after myocardial infarction has declined since the introduction of reperfusion techniques. Nevertheless, ischemic arrhythmias are often associated with increased morbidity and mortality particularly in the first 48 hours after hospital admission. This paper presents a comprehensive review of the epidemiology, characteristics, and management of ischemic tachy-and brady-arrhythmias focusing on the period shortly after myocardial infarction (MI) in patients with both ST-segment elevation myocardial infarction (STEMI) and non-ST-segment elevation myocardial infarction (NSTEMI).
Maternal mortality in the United States is a public health crisis of preventable deaths among young women. The role of echocardiography in the evaluation of pregnant women with cardiovascular symptoms or risk factors without known heart disease is unclear. We retrospectively examined the clinical characteristics of consecutive pregnant patients without established heart disease who underwent echocardiography and evaluated associations between abnormal exam findings and obstetric outcomes. Among low-risk women undergoing echocardiography during pregnancy, older age, higher parity and a history of chronic hypertension are associated with a higher likelihood of echocardiographic abnormalities, which in turn are associated with a higher likelihood of adverse obstetric outcomes including caesarean section and preterm delivery.
Introduction: Flecainide is a class IC anti-arrhythmic used to treat atrial fibrillation. Toxicity can cause bradycardia, QRS prolongation, and ventricular tachyarrhythmia (VT) due to blockade of sodium channels. Although most metabolism occurs through the liver, up to 30% excretion is renal but not dialyzable. The case here represents two arrhythmogenic challenges associated with flecainide treated with alkalization and lipid emulsion. Case: A 75-year-old woman with atrial fibrillation initially presented with syncope and hematemesis. Initial ECG showed junctional bradycardia with narrow escape in HR 30s. Labs notable for creatinine 2.55 (nl <1.2 mg/dl) and potassium 4.8 (3.5-5.0 mmol/L). pH was 7.28 with bicarbonate 18 (22-31 mmol/L). She was treated with glucagon and atropine for suspected B-blocker toxicity but quickly went into shock. Rhythm then changed to a wide complex tachycardia (Fig) with wide QRS 280ms, VT rates in 100s. Due to development of this slow VT, flecainide toxicity was highly suspected, and a bicarbonate drip was started to maintain pH>7.50 in addition to intralipid infusion. In the span of 12 hours, she was able to wean off her vasopressor support. On hospital day 3, she started metoprolol and remained in sinus bradycardia at the time of discharge. Discussion: This case represented acute renal failure secondary to flecainide toxicity and gastrointestinal bleed. Toxicity led to QRS widening and slow VT, which diminished contractility. Serum alkalization and sodium load works to displace flecainide from its channel receptor; intralipid sequesters lipophilic toxin in a “lipid sink” mechanism. In extreme cases, ECMO and overdrive pacing are used. Conclusions: Early recognition of flecainide-related arrhythmias is key. The subsequent approach to flecainide toxicity includes reducing absorption (charcoal, lipid emulsion), antagonizing drug effect (alkalization), and proving hemodynamic support (phenylephrine, vasopressin).
