BACKGROUND: In response to the opioid epidemic and new guidelines, many patients on high-dose long-term opioid therapy (LTOT) for chronic pain are getting tapered off opioids. As a result, a unique clinical challenge is emerging: although many on LTOT have poor pain control, functional decline, psychiatric instability, aberrancies, and misuse, these issues may often worsen with opioid tapering. Currently, a clear explanation and practical guidance on how to manage this perplexing clinical scenario is lacking...

BACKGROUND/AIMS: There have been discrepancies reported in visuo-spatial construction ability in children with Autism Spectrum Disorders (ASD), fragile X Syndrome (FXS) and those with a comorbid diagnosis of FXS and ASD (AFXS). This study aimed to provide a better understanding of the visuo-spatial processing styles in these heterogeneous neurodevelopmental disorders. METHODS AND PROCEDURE: Navon-type tasks were used to assess visuo-spatial construction ability across 5 groups of children: typically developing, FXS, AFXS, ASD children who scored low-moderate (HFA) and ASD children that scored severe (LFA) on the Childhood Autism Rating Scale (CARS)...

In 2016, the American College of Cardiology published the first expert consensus decision pathway (ECDP) on the role of non-statin therapies for low-density lipoprotein (LDL)-cholesterol lowering in the management of atherosclerotic cardiovascular disease (ASCVD) risk. Since the publication of that document, additional evidence and perspectives have emerged from randomized clinical trials and other sources, particularly considering the longer-term efficacy and safety of proprotein convertase subtilisin/kexin 9 (PCSK9) inhibitors in secondary prevention of ASCVD...

BACKGROUND: Aldosterone may have adverse effects in the myocardium and vasculature. Treatment with an aldosterone antagonist reduces cardiovascular risk in patients with acute myocardial infarction complicated by heart failure (HF) and left ventricular systolic dysfunction. However, most patients with acute coronary syndrome do not have advanced HF. Among such patients, it is unknown whether aldosterone predicts cardiovascular risk. METHODS AND RESULTS: To address this question, we examined data from the dal-OUTCOMES trial that compared the cholesteryl ester transfer protein inhibitor dalcetrapib with placebo, beginning 4 to 12 weeks after an index acute coronary syndrome...

Marked fluid retention occurs in Ballantyne syndrome, but few reports are available on changes in cardiac morphology in this syndrome. A woman with generalized edema, dyspnea, fetal hydrops (skin edema and ascites), thickened placenta, and elevated plasma B-type natriuretic peptide level (344 pg/mL) was admitted to our hospital at gestational week (GW) 20(+3) . Blood pressure remained within the normal range. However, acute increases in left atrial volume index, pulmonary artery systolic pressure, and hyperdynamic left ventricular function (as evidenced by increased left ventricular ejection fraction to 74% with cardiac index of 5...

Background Metabolic syndrome (MetS) is associated with increased risk for cardiovascular disease, but there is heterogeneity in this risk. We evaluated whether high-sensitivity troponin T (hs-cTnT), a marker associated with cardiovascular disease, can stratify risk in MetS. Methods We evaluated associations between MetS (and groups with similar number of MetS components) and incident heart failure hospitalization, coronary heart disease, stroke and death using hs-cTnT categories after adjusting for risk factors/markers between 1996 and 2011 in 8204 individuals in the Atherosclerosis Risk In Communities study...

BACKGROUND: We aimed to determine the efficacy and safety of adding ezetimibe (Ez) to simvastatin (S) in a post-acute coronary syndrome (ACS) population in a prespecified on-treatment analysis. METHODS: We evaluated 17,706 post-ACS patients from the IMPROVE-IT trial who had low-density lipoprotein cholesterol values between 50 and 125 mg/dL and who received Ez 10 mg/d with S 40 mg/d (Ez/S) or placebo with simvastatin 40 mg/d (P/S). The primary composite end point was cardiovascular death, myocardial infarction, unstable angina, coronary revascularization ≥30 days postrandomization, or stroke...

CONTEXT: Postprandial hyperlipidemia has been suggested to contribute to atherogenesis by inducing proinflammatory changes in monocytes. Individuals with metabolic syndrome (MS), shown to have higher blood triglyceride concentration and delayed triglyceride clearance, may thus have increased risk for development of atherosclerosis. OBJECTIVE: Our objective was to examine fasting levels and effects of a high-fat meal on phenotypes of monocyte subsets in individuals with obesity and MS and in healthy controls...

We report a pregnant woman who was monitored by echocardiography and determination of blood variables, including components of the renin-angiotensin-aldosterone system (RAAS), cardiac biomarkers and soluble fms-like tyrosine kinase-1 (sFlt-1), during and after the development of Ballantyne syndrome. Generalised maternal oedema with dyspnoea following fetal and placental hydrops necessitated a caesarean section at 33 weeks of gestation. Changes in blood variables and simultaneous echocardiography changes indicated acutely enhanced RAAS and hyperdynamic left ventricular function in response to excessive volume overload (as evidenced by brain-type natriuretic peptide level of 523 pg/mL) in the absence of increased systemic vascular resistance...

BACKGROUND/AIMS: Despite the advances in understanding visuo-spatial processing in developmental disorders such as ASD and fragile X syndrome (FXS), less is known about the profile of those with a comorbid diagnosis, or the role of within-disorder disparities between individuals across the ASD spectrum. METHODS AND PROCEDURES: Using a developmental trajectory approach, we tested 5 groups of children: Typically developing, FXS, FXS+ASD, ASD individuals who had low-moderate symptoms (HFA) and ASD individuals who had severe symptoms (LFA)...

Mirror syndrome is also known as Ballantyne syndrome, maternal hydrops, triple edema and pseudotoxemia. The disease can be difficult to diagnose, is related to pregnancy and can grievously endanger the health of both the mother and fetus. The pathogenesis of the disease has not been fully elucidated, and this disease may be confused with preeclampsia, even though distinguishing features can be identified. In this report case, we describe a pregnant woman who suffered from mirror syndrome associated with heart failure...

BACKGROUND: Metabolic syndrome (MetS) and insulin resistance (IR) are increasing in prevalence, are associated with higher risk for coronary heart disease (CHD), and may potentially influence the responses to lipid-altering drug therapy. This study evaluated the effects of MetS factors (abdominal obesity, depleted high-density lipoprotein cholesterol [HDL-C], and elevated triglycerides, blood pressure, and fasting glucose) and IR on ezetimibe/simvastatin and atorvastatin treatment efficacy in patients with MetS...

PURPOSE: In the IMProved Reduction of Outcomes: Vytorin Efficacy International Trial (IMPROVE-IT), simvastatin/ezetimibe combination was associated with a 6% relative risk reduction in the combined cardiovascular outcome compared with simvastatin alone in patients with acute coronary syndrome. Given strict inclusion criteria (low-density lipoprotein cholesterol 50-125 mg/dL and no use of statins more potent than simvastatin 40 mg), the implications of this important trial in routine acute coronary syndrome care are unknown...

Andes virus (ANDV) and ANDV-like viruses are responsible for most hantavirus pulmonary syndrome (HPS) cases in South America. Recent studies in Chile indicate that passive transfer of convalescent human plasma shows promise as a possible treatment for HPS. Unfortunately, availability of convalescent plasma from survivors of this lethal disease is very limited. We are interested in exploring the concept of using DNA vaccine technology to produce antiviral biologics, including polyclonal neutralizing antibodies for use in humans...

Polyclonal immunoglobulin-based medical products have been used successfully to treat diseases caused by viruses for more than a century. We demonstrate the use of DNA vaccine technology and transchromosomal bovines (TcBs) to produce fully human polyclonal immunoglobulins (IgG) with potent antiviral neutralizing activity. Specifically, two hantavirus DNA vaccines [Andes virus (ANDV) DNA vaccine and Sin Nombre virus (SNV) DNA vaccine] were used to produce a candidate immunoglobulin product for the prevention and treatment of hantavirus pulmonary syndrome (HPS)...

In this case, we describe a newborn with prenatal diagnosis of congenital high airway obstruction syndrome (CHAOS), successfully managed with a cesarean section with delayed cord clamping 180 seconds. In case of prenatal diagnosis of CHAOS, prompt airway intervention at delivery allows survival of this otherwise fatal condition. Ex utero intrapartum treatment (EXIT) is considered the elective procedure to secure the fetal airway before the baby is completely separated from the maternal circulation. In cases where the EXIT procedure is not possible for maternal reasons (Ballantyne's syndrome), delayed cord clamping may serve as an alternative method to manage CHAOS...

OBJECTIVES: It is unknown which measure of adiposity (body mass index [BMI] or waist circumference [WC]) is associated with subclinical atherosclerosis in retired National Football League (NFL) players and whether this relation is attenuated after adjusting for components of the metabolic syndrome (elevated triglycerides, fasting glucose, and low levels of high-density lipoprotein-cholesterol [HDL-C]) that frequently coexist with obesity. METHODS: Coronary artery calcium (CAC) was measured in 926 retired NFL players...
