    Abstract: Kratom is an herb indigenous to Southeast Asia with psychoactive opioid compounds, often used as a treatment for chronic pain or opiate withdrawal symptoms. It is legally and readily available via Internet sales and has been identified as an emerging drug of abuse in the United States. Kratom use has been associated with psychosis, seizures, and even death. At lower doses, kratom acts as a stimulant, while at higher doses, it produces analgesia and euphoria. Here, we describe the successful management of kratom overdose and withdrawal in a young man with negative toxicology screens.

    Abstract: Introduction: Pulmonary arterial hypertension (PAH) is a relative common complication in patients with congenital heart disease (CHD), affecting both disease progression and prognosis. The pathogenic mechanisms that lead to “irreversible” PAH are therefore poorly understood in subjects with CHD. Hypothesis: The aim of this study was to apply proteomics to discover protein regulations in the lungs of irreversible PAH patients, which could lead to generation of new hypotheses concerning signaling pathways and elucidating the pathophysiology of irreversible PAH. Methods: Label-free liquid chromatography tandem mass spectrometry was used to compare protein profiles in surgical samples of lungs from 4 patients with irreversible CHD-PAH, 4 reversible CHD-PAH and 4 control subjects. Result: A total of 133 proteins were differently expressed. The majority of differential expressed proteins were associated with cytoskeleton remodeling, integrin-mediated cell adhesion and migration, endothelial cell contacts, blood coagulation and HDL-mediated reverse cholesterol transport. Novel findings included increased expression of filamin A and caveolin-1 and decreased expression of glutathione S-transferase (GST) family. Filamin A, a major isoform of the filamin family which is a family of cytoskeletal proteins that have been implicated as critical mediators of organ development and cell signaling and migration. In the present study, the density and cellular location of filamin A immunoreactivity was accordant with caveolin-1. The results were confirmed by Western blot and immunohistochemistry. In reversible CHD-PAH and control lung tissue, filamin A and caveolin-1 were prominent in endothelium of pulmonary arteriole. In irreversible CHD-PAH lung tissue, they were prominent in the vascular smooth muscle cell. Conclusions: Label-free proteomics identified differences in the expression of several proteins in the CHD-PAH lung, many of which are relevant to the cell proliferation, differentiation and migration. Increased expression of filamin A and caveolin-1 may be pertinent to the proliferation and migration of vascular smooth muscle cell. Decreased expression of GST indicated impaired anti-oxidative function in irreversible CHD-PAH.

    Abstract: Coronary artery disease (CAD) is the commonest cause of heart failure (HF), whereas pulmonary hypertension (PH) has not been established or reported in this patient population. Therefore, we assessed the prevalence, risk factors, and survival in CAD-associated HF (CAD-HF) complicated with PH. Methods: Symptomatic CAD-HF patients were continuously enrolled in this prospective, multicenter registry study. Echocardiography, coronary arteriography, left and right heart catheterization (RHC), and other baseline clinical data were recorded. Patients were followed up and their survival was recorded. Results: One hundred and eighty-two CAD-HF patients were enrolled, including 142 with HF with a preserved ejection fraction (heart failure with preserved ejection fraction [HFpEF]; left ventricular ejection fraction [LVEF] ≥50%) and 40 with a reduced ejection fraction (heart failure with reduced ejection fraction [HFrEF]; LVEF 〈 50%). PH was diagnosed with RHC in 77.5% of patients. Patients with PH showed worse hemodynamic parameters and higher mortality. HFrEF-PH patients had worse survival than HFpEF-PH patients. CAD-HF patients with an enlarged left ventricular end-diastolic diameter and reduced hemoglobin were at higher risk of PH. Nitrate treatment reduced the risk of PH. Elevated creatinine and mean pulmonary arterial pressure (mPAP), diastolic pressure gradient (DPG) ≥7 mmHg, and previous myocardial infarction (MI) entailed a higher risk of mortality in CAD-HF patients with PH. Conclusions: PH is common in CAD-HF and worsens the hemodynamics and survival in these patients. Left ventricle enlargement and anemia increase the risk of PH in CAD-HF. Patients may benefit from nitrate medications. Renal impairment, elevated mPAP, DPG ≥7 mmHg, and previous MI are strong predictors of mortality in CAD-HF-PH patients.

    Abstract: Self‐rated health ( SRH ) is a strong predictor of mortality in different populations. However, the associations between SRH measures and risk of ischemic heart disease ( IHD ) have not been extensively explored, especially in a Chinese population. Methods and Results More than 500 000 adults from 10 cities in China were followed from baseline (2004–2008) through December 31, 2013. Global and age‐comparative SRH were reported from baseline questionnaires. Incident IHD cases were identified through links to well‐established disease registry systems and the national health insurance system. During 3 423 542 person‐years of follow‐up, we identified 24 705 incident cases of IHD . In multivariable‐adjusted models, both global and age‐comparative SRH was significantly associated with incident IHD . Compared with excellent SRH , the hazard ratios for good, fair, and poor SRH were 1.02 (95% confidence interval [CI], 0.98–1.07), 1.32 (95% CI, 1.27–1.37), and 1.76 (95% CI, 1.68–1.85), respectively. Compared with better age‐comparative SRH , the hazard ratios for same and worse age‐comparative SRH were 1.23 (95% CI, 1.19–1.27) and 1.78 (95% CI, 1.70–1.86), respectively. The associations persisted in all subgroup analyses, although they were slightly modified by study location, education, and income levels. Conclusions A simple questionnaire for self‐assessment of health status was significantly associated with incident IHD in Chinese adults. Individuals and healthcare providers can use SRH measures as a convenient tool for assessing future IHD risk.

    Abstract: Most cardiovascular diseases occur in low‐ and middle‐income regions of the world, but the socioeconomic distribution within China remains unclear. Our study aims to investigate whether the prevalence of cardiovascular diseases differs among high‐, middle‐, and low‐income regions of China and to explore the reasons for the disparities. Methods and Results We enrolled 46 285 individuals from 115 urban and rural communities in 12 provinces across China between 2005 and 2009. We recorded their medical histories of cardiovascular diseases and calculated the INTERHEART Risk Score for the assessment of cardiovascular risk‐factor burden, with higher scores indicating greater burden. The mean INTERHEART Risk Score was higher in high‐ and middle‐income regions than in low‐income regions (9.47, 9.48, and 8.58, respectively, P 〈 0.0001). By contrast, the prevalence of total cardiovascular disease (stroke, ischemic heart disease, and other heart diseases that led to hospitalization) was lower in high‐ and middle‐income regions than in low‐income regions (7.46%, 7.42%, and 8.36%, respectively, P trend =0.0064). In high‐ and middle‐income regions, urban communities have higher INTERHEART Risk Score and higher prevalent rate than rural communities. In low‐income regions, however, the prevalence of total cardiovascular disease was similar between urban and rural areas despite the significantly higher INTERHEART Risk Score for urban settings. Conclusions We detected an inverse trend between risk‐factor burden and cardiovascular disease prevalence in urban and rural communities in high‐, middle‐, and low‐income regions of China. Such asymmetry may be attributed to the interregional differences in residents’ awareness, quality of healthcare, and availability and affordability of medical services.
