Stroke and stroke risk factors in women of reproductive age with a history of metabolic or bariatric surgery

ObjectiveTo determine the odds of stroke in women of reproductive age who have had metabolic or bariatric surgery (MBS).MethodsWe used the National Inpatient Sample (NIS), a publicly available dataset that samples 20% of hospital discharges. The study population includes women between the ages of 20 and 44 without a maternal admission code. Weighted logistic regression analyses were conducted to assess the odds of stroke in women with history of MBS compared to other women of reproductive age. Adjustment of odds was done for the following covariates: age, race, primary payer, severity of illness, depression, and obesity.ResultsWomen with a history of MBS had 52% lower adjusted odds of having a stroke than women who did not have MBS (OR = 0.48, 95%CI = 0.42-0.55). Additionally, women who had MBS had lower odds of risk factors for stroke, including diabetes (OR = 0.61, 95%CI = 0.59-0.63), hypertension (OR = 0.82, 95%CI = 0.81-0.84), hypercholesterolemia (OR=0.72, 95%CI =0.68-0.77), and migraine with aura (OR = 0.86, 95%CI = 0.74-0.99).ConclusionsAmong women of reproductive age with a history of MBS, there were lower odds of having a stroke and stroke risk factors when compared to women who did not have MBS. Additionally, this study showed a modest decrease in the odds of stroke among women with obesity when adjusted for other risk factors. Future research should focus on examining this finding further, with a focus on the moderation of the impact of having obesity on stroke risk independent of other stroke risk factors.     

Gut microbes in pediatric ALL survivorship

ABSTRACT

Acute lymphoblastic leukemia (ALL) is the most common childhood cancer and has a 5?year survival rate of greater than 90%. Despite this extraordinary success, survivors face lifelong chronic health problems including a predisposition to obesity, metabolic syndrome, and resulting complications like cardiovascular disease. In this issue, Thomas et al. (Yang laboratory) investigated the gut microbiome in pediatric ALL survivors and healthy sibling controls. They identified key changes in operational taxonomic units (OTUs), which have been linked previously to obesity and metabolic syndrome. This study suggests that dysbiosis, which can predispose to life-long secondary complications of ALL, begins in childhood immediately after treatment and opens an ample window for interventions aimed at reducing obesity and metabolic syndrome in ALL survivors.     

“Healing is a Done Deal”: Temporality and Metabolic Healing Among Evangelical Christians in Samoa

Drawing on fieldwork in independent Samoa, in this article, I analyze the temporal dimensions of evangelical Christian healing of metabolic disorders. I explore how those suffering with metabolic disorders draw from multiple time-based notions of healing, drawing attention to the limits of biomedicine in contrast with the effectiveness of Divine healing. By simultaneously engaging evangelical and biomedical temporalities, I argue that evangelical Christians create wellness despite sickness and, in turn, re-signify chronic suffering as a long-term process of Christian healing. Positioning biomedical temporality and evangelical temporality as parallel yet distinctive ways of practicing healing, therefore, influences health care choices.     

Nonalcoholic Fatty Liver Disease and the Heart: JACC State-of-the-Art Review

Nonalcoholic fatty liver disease (NAFLD) and cardiovascular disease (CVD) are both manifestations of end-organ damage of the metabolic syndrome. Through multiple pathophysiological mechanisms, CVD and NAFLD are associated with each other. Systemic inflammation, endothelial dysfunction, hepatic insulin resistance, oxidative stress, and altered lipid metabolism are some of the mechanisms by which NAFLD increases the risk of CVD. Patients with NAFLD develop increased atherosclerosis, cardiomyopathy, and arrhythmia, which clinically result in cardiovascular morbidity and mortality. Defining the mechanisms linking these 2 diseases offers the opportunity to further develop targeted therapies. The aim of this comprehensive review is to examine the association between CVD and NAFLD and discuss the overlapping management approaches.     

扁塑藤素调控Notch信号通路诱导人肺癌条件重编程细胞死亡的作用机制研究

目的：应用条件性重编程细胞（conditionally reprogrammed cells，CRCs）技术建立人肺癌细胞体外长期培养体系，研究扁塑藤素对人肺癌CRCs增殖和迁移能力的影响，并探讨相关作用机制。方法：免疫组化法检测Notch 1、HES1和Cyclin D3在肿瘤组织和癌旁组织中的表达水平；使用CRCs技术分离培养非小细胞肺癌原代细胞；使用2，4，8，16 μmol·L^-1的扁塑藤素处理人肺癌CRCs，MTS法检测细胞活力，Annexin V/PI流式细胞术检测细胞凋亡，Transwell法检测细胞迁移能力，Western Blot检测细胞中Notch信号通路相关蛋白Notch 1、HES1和Cyclin D3的表达水平。结果：在非小细胞肺癌患者肿瘤组织中Notch 1、HES1和Cyclin D3的表达水平高于癌旁组织；扁塑藤素能够诱导人肺癌CRCs死亡，并在一定范围内呈现时间和浓度依赖性（P<0.05）；随着扁塑藤素作用浓度的增高，人肺癌CRCs凋亡率明显增高（P<0.05），细胞迁移能力下降（P<0.05）；扁塑藤素能够下调人肺癌CRCs中Notch 1、HES1和Cyclin D3的蛋白表达水平。结论：扁塑藤素可能通过调控Notch信号通路相关蛋白的表达水平，抑制人肺癌CRCs的增殖和迁移，并诱导其凋亡，为肺癌的治疗提供新的实验数据和理论依据。     

CYP2C19*3基因多态性对癫痫患者奥卡西平活性代谢产物MHD浓度的影响

目的：分析CYP2C19*3基因多态性与癫痫患者奥卡西平（oxcarbazepine，OXC）活性代谢产物10，11-二氢-10-羟基卡马西平（monohydroxycarbazepine，MHD）血药浓度的相关性。方法：纳入120例OXC单药治疗1个月以上且症状控制良好的癫痫患者，采集清晨服药前空腹血，采用高效液相色谱法测定MHD稳态谷浓度。通过PCR和sanger测序判定患者CYP2C19*3基因型。结果：120例癫痫患者快代谢患者64例，MHD血浆浓度为（18.17±7.34）μg·mL^-1；中代谢型患者36例，MHD血浆浓度为（19.31±9.17）μg·mL^-1；慢代谢型患者20例，MHD血浆浓度为（25.79±7.51）μg·mL^-1，3种基因型的MHD浓度有显著性差异（F=7.077，P=0.0013）。多因素分析显示，日剂量作为影响血药浓度的重要指标呈现出显著相关性（P<0.05）。结论：CYP2C19*3基因多态性影响MHD血药浓度，并且日剂量越高，MHD血药浓度越大，两者成显著正相关，临床应进行血药浓度监测。
