Weight Loss Reduces Tissue Factor in Morbidly Obese Patients

Objective: To investigate the tissue factor (TF) pathway in clinical obesity and associated metabolic syndrome. Research Methods and Procedures: Thirty‐seven morbidly obese patients (4 men; BMI, 48 ± 7 kg/m²; range, 42 to 53 kg/m²), undergoing elective gastroplasty for the induction of weight loss, were examined for hemostatic, metabolic, and inflammatory parameters at baseline and 14 ± 5 months postoperatively. Results: Weight loss significantly reduced circulating plasma TF (314 ± 181 vs. 235 ± 113 pg/mL, p = 0.04), coagulation factor VII (130 ± 22% vs. 113 ± 19%, p = 0.023), and prothrombin fragment F1.2 (2.4 ± 3.4 vs. 1.14 ± 1.1 nM, p = 0.04) and normalized glucose metabolism in 50% of obese patients preoperatively classified as diabetic or of impaired glucose tolerance. The postoperative decrease in plasma TF correlated with the decrease of F1.2 (r = 0.56; p = 0.005), a marker of in vivo thrombin formation. In subgroup analysis stratified by preoperative glucose tolerance, baseline circulating TF (402.6 ± 141.6 vs. 176.2 ± 58.2, p < 0.001) and TF decrease after gastroplasty (ΔTF: 164.7 ± 51.4 vs. ?81 ± 31 pg/mL, p = 0.02) were significantly higher in obese patients with impaired glucose tolerance than in patients with normal glucose tolerance. Discussion: Procoagulant TF is significantly reduced with weight loss and may contribute to a reduction in cardiovascular risk associated with obesity.

Irregular 24-hour activity rhythms and the metabolic syndrome in older adults

Circadian rhythms – near 24?h intrinsic biological rhythms – modulate many aspects of human physiology and hence disruption of circadian rhythms may have an important impact on human health. Experimental work supports a potential link between irregular circadian rhythms and several key risk factors for cardiovascular disease including hypertension, obesity, diabetes and dyslipidemia, collectively termed the metabolic syndrome. While several epidemiological studies have demonstrated an association between shift-work and the components of the metabolic syndrome in working-age adults, there is a relative paucity of data concerning the impact of non-occupational circadian irregularity in older women and men. To address this question, we studied 7 days of actigraphic data from 1137 older woman and men participating in the Rush Memory and Aging Project, a community-based cohort study of the chronic conditions of aging. The regularity of activity rhythms was quantified using the nonparametric interdaily stability metric, and was related to the metabolic syndrome and its components obesity, hypertension, diabetes and dyslipidemia. More regular activity rhythms were associated with a lower odds of having the metabolic syndrome (OR?=?0.69, 95% CI?=?0.60–0.80, p?=?5.8?×?10^?7), being obese (OR?=?0.73, 95% CI?=?0.63–0.85, p?=?2.5?×?10^?5), diabetic (OR?=?0.76, 95% CI?=?0.65–0.90, p?=?9.3?×?10^?4), hypertensive (OR?=?0.78, 95% CI?=?0.66–0.91, p?=?2.0?×?10^?3) or dyslipidemic (OR?=?0.82, 95% CI?=?0.72–0.92, p?=?1.2?×?10^?3). These associations were independent of differences in objectively measured total daily physical activity or rest, and were not accounted for by prevalent coronary artery disease, stroke or peripheral artery disease. Moreover, more regular activity rhythms were associated with lower odds of having cardiovascular disease (OR?=?0.83; 95% CI?=?0.73–0.95, p?=?5.7?×?10^?3), an effect that was statistically mediated by the metabolic syndrome. We conclude that irregular activity rhythms are associated with several key components of the metabolic syndrome in older community-dwelling adults, and that the metabolic syndrome statistically partially mediates the association between activity rhythms and prevalent cardiovascular disease. Although additional longitudinal and experimental studies are needed to conclusively delineate the causal relationships underlying these associations, these findings are consistent with preclinical data, and add further support for investigations of the irregularity of activity rhythms as a potential therapeutic target to decrease the burden of cardiovascular disease in older adults.     

Relationship Between Metabolic Syndrome,Circadian Treatment Time,and Blood Pressure Non-Dipping Profile in Essential Hypertension

There is a strong association between metabolic syndrome (MS) and increased cardiovascular risk. Moreover, elevated nighttime blood pressure (BP) and non-dipping (subjects with <10% decline in the asleep relative to the awake BP mean) have been also linked to increased cardiovascular morbidity and mortality. We investigated the relation between MS, circadian time of hypertension treatment, and impaired nighttime BP decline in a cross-sectional study on 3352 (1576 men/1776 women) non-diabetic hypertensive subjects, 53.7?±?13.1 (mean?±?SD) yrs of age. Among them, 2056 were ingesting all their prescribed hypertension medication upon awakening, and 1296 were ingesting at least one of their BP medications at bedtime. BP was measured by ambulatory monitoring for 48 consecutive hours to substantiate reproducibility of the dipping pattern. Physical activity was simultaneously monitored every minute by wrist actigraphy to accurately calculate mean BP when awake and asleep for each subject. MS was present in 52.6% of the subjects. The prevalence of an altered non-dipper BP profile was significantly higher among subjects with MS (52.0% vs. 39.5% in subjects without MS, p < .001). Non-dipping was significantly more prevalent among subjects ingesting all BP-lowering medications upon awakening (56.8%) than among those ingesting at least one of their BP medications at bedtime (29.1%; p < .001). Subjects with MS had significantly higher values of uric acid (6.0 vs. 5.3?mg/dL, p < .001), plasma fibrinogen (331 vs. 315?mg/dL, p < .001), and erythrocyte sedimentation rate (14.8 vs. 12.4?mm, p < .001). Non-dipping was significantly associated with the presence of MS and treatment upon awakening in a multiple logistic regression model adjusted by significant confounding factors, including age, creatinine, erythrocyte sedimentation rate, and cigarette smoking. This cross-sectional study documents a significant increase of a blunted sleep-time BP decline in treated hypertensive subjects with MS. Even in the presence of MS, treatment at bedtime is significantly associated with lower prevalence of a high-risk non-dipper BP profile. (Author correspondence: rhermida@uvigo.es)     

Night Eating Syndrome Is Associated with Depression,Low Self‐Esteem,Reduced Daytime Hunger,and Less Weight Loss in Obese Outpatients

Objective: The objective of this study was to assess the relationship between the night eating syndrome (NES), measures of depression and self‐esteem, test meal intake, and weight loss in obese participants. Research Methods and Procedures: The study included 76 overweight (body mass index = 36.7 ± 6.5 SD) outpatients (53 women and 23 men; aged 43.5 ± 9.5 years) entering a weight loss program. They completed a Night Eating Questionnaire, the Zung Depression Inventory, and the Rosenberg Self‐Esteem Scale. Based on criteria by Stunkard et al. (Stunkard A, Berkowitz R, Wadden T, Tanrikut C, Reiss E, Young L. Binge eating disorder and the night eating syndrome. Int J Obes Relat Metab Disord. 1996;20:1–6), participants had NES if they reported: (1) skipping breakfast ≥4 d/wk, interpreted as morning anorexia; (2) consuming more than 50% of total daily calories after 7 pm ; and (3) difficulty falling asleep or staying asleep ≥4 d/wk. Eleven (14%) participants met the criteria for NES. After an 8‐hour fast, all participants ingested a nutritionally complete liquid meal through a straw from a large opaque cooler until extremely full. They also completed ratings of hunger and fullness before and after this meal. Results: Night eaters had higher depression (p = 0.04), lower self‐esteem (p = 0.003), and less hunger (p = 0.005), and a trend for more fullness (p = 0.06) before the daytime test meal than the others. However, there were no significant differences in test‐meal intake between groups. Nevertheless, test‐meal intake was greater later in the day only for the night eaters (p = 0.01). Over a 1‐month period, the night eaters lost less weight (4.4 ± 3.2 kg) than the others (7.3 ± 3.2 kg; p = 0.04), after controlling for body mass index. Discussion: NES is a syndrome with distinct psychopathology and increased food intake later in the day, both of which may contribute to poorer weight loss outcome. NES criteria need to be better quantified and NES deserves consideration as a diagnostic eating disorder.

A meta‐analysis of cardio‐metabolic abnormalities in drug naïve,first‐episode and multi‐episode patients with schizophrenia versus general population controls

A meta‐analysis was conducted to explore the risk for cardio‐metabolic abnormalities in drug naïve, first‐episode and multi‐episode patients with schizophrenia and age‐ and gender‐ or cohort‐matched general population controls. Our literature search generated 203 relevant studies, of which 136 were included. The final dataset comprised 185,606 unique patients with schizophrenia, and 28 studies provided data for age‐ and gender‐matched or cohort‐matched general population controls (n=3,898,739). We found that multi‐episode patients with schizophrenia were at increased risk for abdominal obesity (OR=4.43; CI=2.52‐7.82; p<0.001), hypertension (OR=1.36; CI=1.21‐1.53; p<0.001), low high‐density lipoprotein cholesterol (OR=2.35; CI=1.78‐3.10; p<0.001), hypertriglyceridemia (OR=2.73; CI=1.95‐3.83; p<0.001), metabolic syndrome (OR=2.35; CI=1.68‐3.29; p<0.001), and diabetes (OR=1.99; CI=1.55‐2.54; p<0.001), compared to controls. Multi‐episode patients with schizophrenia were also at increased risk, compared to first‐episode (p<0.001) and drug‐naïve (p<0.001) patients, for the above abnormalities, with the exception of hypertension and diabetes. Our data provide further evidence supporting WPA recommendations on screening, follow‐up, health education and lifestyle changes in people with schizophrenia.

摘要 目的：探究慢性阻塞性肺疾病急性加重期（AECOPD）合并肺动脉高压（PH）患者血清同型半胱氨酸（Hcy）、胱抑素C（Cys-C）水平与肺功能、动脉血气分析指标及肺动脉收缩压的关系。方法：选择2017年12月至2019年12月我院诊治的80例AECOPD合并PH患者作为AECOPD合并PH组。同时选择80例AECOPD未合并PH患者作为单纯AECOPD组以及50名在我院进行体检的健康志愿者作为健康组。检测并比较各组受试者的血清Hcy和Cys-C水平、第一秒用力呼气容积占用力肺活量比值(FEV₁/FVC）、动脉氧分压（PaO₂）、第一秒用力呼气容积占预计值的百分比（FEV₁%pred）、动脉二氧化碳分压（PaCO₂）,肺动脉收缩压（PASP）,分析各指标的相关性。结果：AECOPD合并PH组血清Hcy、Cys-C水平以及PASP最高,其次为单纯AECOPD组,健康组最低（P<0.05）。健康组FEV₁%pred、FEV₁/FVC最高,其次为单纯AECOPD组,AECOPD合并PH组最低（P<0.05）。与单纯AECOPD组相比,AECOPD合并PH组PaO₂明显下降,PaCO₂明显升高（P<0.05）。经Pearson相关性分析可得,血清Hcy和Cys-C与FEV₁%pred、FEV₁/FVC和PaO₂均呈负相关（P<0.05）,而与PaCO₂和PASP均呈正相关（P<0.05）。结论：血清Hcy和Cys-C水平异常升高与AECOPD患者并发PH相关,并且与AECOPD合并PH患者肺功能下降、动脉血气异常以及PASP异常升高存在相关性。     

坐式八段锦联合运动康复治疗对急性冠脉综合征PCI术后患者运动耐力、血清心肌损伤标志物和生活质量的影响

摘要 目的：探讨坐式八段锦联合运动康复治疗对急性冠脉综合征（ACS）经皮冠状动脉介入治疗术（PCI）后患者运动耐力、血清心肌损伤标志物和生活质量的影响。方法：根据随机数字表法,将我院2020年4月~2021年5月期间收治的ACS行PCI术的患者（n=120）分为对照组（运动康复治疗,n=60）和研究组（坐式八段锦联合运动康复治疗,n=60）。对比两组心功能指标[左心室舒张末期内径（LVEDD）、左心室射血分数（LVEF）、氨基末端B型脑利钠肽前体（NT-proBNP）、左心室舒张末期容积（LVEDV）]、心肌损伤标志物[肌酸激酶同工酶（CK-MB）、心肌肌钙蛋白I（cTnI）]、运动耐力指标[无氧阈（AT）、最大摄氧量（VO_2max ）、运动持续时间（ED）]和生活质量[西雅图心绞痛量表（SAQ）评分：躯体活动受限程度（PL）、心绞痛稳定情况（AS）、疾病认知程度（DS）、心绞痛发作状况（AF）和治疗满意程度（TS）],并纪录两组不良心血管事件发生情况。结果：研究组的心血管不良事件发生率低于对照组（P<0.05）。研究组治疗3个月后LVEF高于对照组,LVEDD、LVEDV、NT-proBNP低于对照组（P<0.05）。研究组治疗3个月后CK-MB、cTnI低于对照组（P<0.05）。研究组治疗3个月后AT、VO_2max 、ED高于对照组（P<0.05）。研究组治疗3个月后PL、AS、DS、AF、TS评分高于对照组（P<0.05）。结论：坐式八段锦联合运动康复治疗可促进ACS患者PCI术后心功能改善,减轻心肌损伤,进而提高运动耐力和生活质量。
