Effect of female sex hormone supplementation and withdrawal on gastrointestinal and colonic transit in postmenopausal women

Females are disproportionately affected by constipation, which is often aggravated during pregnancy. Bowel function also changes during the luteal phase of the menstrual cycle. The aim was to compare the effects of acute administration of female sex steroids on gastric emptying, small bowel transit and colonic transit in healthy postmenopausal subjects. A second aim was to determine whether withdrawal of the hormones was associated with a change in transit. Forty-nine postmenopausal females were randomized to receive for 7 days 400 mg day(-1) micronized progesterone, 0.2 mg day(-1) oestradiol, combination of the two, or placebo. Treatment groups were balanced on age. Participants underwent whole gut transit measurement by scintigraphy using a 99m-labeled technetium-egg meal and 111-labeled indium-charcoal via a delayed-release capsule. Transit measurement was repeated after withdrawal of the study medications. The primary endpoints were ascending colon (AC) emptying half-life time (t1/2) and colonic geometric centre (GC) at 24 h. Secondary analysis variables were GC at 4 and 48 h, gastric emptying t1/2 and colonic filling at 6 h. There was a significant overall effect of progesterone on colonic transit with shorter AC emptying t1/2 and significantly greater colonic GC at 48 h. No transit endpoints were altered by oestradiol or combined hormonal treatment relative to placebo. Oestradiol and progesterone resulted in looser stool consistency. Withdrawal of the hormone supplement was not associated with significant alteration in transit. Micronized progesterone does not retard colonic transit in postmenopausal females.

The Relationship Between Daily Life Stress and Gastrointestinal Symptoms in Women with Irritable Bowel Syndrome

Research on irritable bowel syndrome (IBS), a functional disorder of the gastrointestinal (GI) system, has linked GI symptoms to stress. This study examined the relationship between daily stress and GI symptoms across women and within woman in IBS patients (n = 26), IBS nonpatients (IBS-NP; n = 23), and controls (n = 26), controlling for menstrual cycle phase. Women (ages 20–45) completed daily health diaries for two cycles in which they monitored daily GI symptoms and stress levels. The Life Event Survey (LES) was used as a retrospective measure of self-reported stress. The across-women analyses showed higher mean GI symptoms and stress in the IBS and IBS-NP groups relative to controls but no group differences in LES scores. The within-woman analyses found a significant and positive relationship between daily stress and daily symptoms in both the IBS-NP and the IBS groups. Controlling for menstrual cycle had no substantial impact on the results.     

罗格列酮联合胰岛素治疗老年2型糖尿病的临床观察

目的　探讨罗格列酮 (RSG)联合胰岛素 (INS)治疗单用INS血糖控制不佳的老年 2型糖尿病 (DM)患者的临床疗效及安全性。方法　将 68例单用INS疗效不佳的老年 2型DM患者随机分为两组各 3 4例 :对照组继续使用合适剂量的胰岛素治疗 ;治疗组在原剂量胰岛素的基础上加服RSG 4mg/d共 2 0周。观察治疗后 4周及 2 0周患者的空腹血糖 (FBG)、餐后 2h血糖 (PBG)、糖化血红蛋白 (HbA1c)、2 4h尿白蛋白排泄率 (UAER)、每日INS用量变化及药物的不良反应等。结果　治疗组 4周后FBG、PBG下降 (P均 <0 0 5 ) ,治疗 2 0周后以上指标下降更显著 ,并使HbA1C、UAER、舒张压、TG及平均每日INS用量下降 ,差异具显著性 (P均 <0 0 5 ) ;对照组治疗后血糖及HbA1c也有一定下降 ,但INS需要量及低血糖发生率明显增加。结论　RSG确实能有效改善老年 2型DM患者的血糖控制 ,治疗安全有效。该药还能改善代谢综合征的一些异常 ,从而对心血管起到保护作用     

Body composition in the elderly: Total body water and anthropometry

Body composition measured with isotopic dilution was compared with anthropometric measurements. The study was carried out in 47 subjects from both sexes, 65 to 92 years old. Total body water (TBW), anthropometric measurements, and dynamometry were assessed. TBW was significatively higher in men than women and decreased with age. Dynamometry and fatfree mass were well correlated (r=0.73 in males and r=0.58 in females) and significantly different between sexes. A negative correlation was found for dynamometry with age, being significant for women. Linear regression equations to predict TBW from anthropometric measurements in males and females were obtained: Males: TBW(I)=19.349+0.617 weight(kg) — 0.931 mid-arm circumference(cm)+0.122 dynamometry (kg) Females: TBW(l)=−5.531+0.343 weight(kg)-0.213 triceps skinfold (mm)+ 0.148 dynamometry(kg) + 3.424 wrist diameter (cm). This simple model is proposed for use in epidemiological and field studies where other more sophisticated methods can not be applied.
