BACKGROUND & AIMS: :Japanese people in both Japan and in Hawaii have a lower incidence of hip fractures than white people in Hawaii or on the mainland of the United States. Hip fractures usually occur after a fall, and differing incidence rates of falls might contribute to the observed differences in hip fracture rates. To investigate this possibility we undertook a prospective study of falls among elderly Japanese men and women living in Hawaii using intensive surveillance methods similar to those used in studies of predominantly white populations. For our Japanese participants, the incidence rates of total falls were 139 per 1000 person years for men and 276 per 1000 person years for women. Age adjusted rate ratios of falls for predominantly white populations compared with our Japanese participants ranged from 1.8 to 2.3 for women and from 2.6 to 4.7 for men. The risk of injuries when they did fall, however, was not lower for our Japanese participants than reported for white participants. For our Japanese population, past falls, female gender, and daytime hours were associated with an increased incidence of falls.

背景与目标： : 日本和夏威夷的日本人髋部骨折的发生率都比夏威夷或美国本土的白人低。髋部骨折通常发生在跌倒后，不同的跌倒发生率可能会导致观察到的髋部骨折发生率差异。为了调查这种可能性，我们使用了类似于以白人为主的研究中使用的强化监测方法，对居住在夏威夷的日本老年男性和女性的跌倒进行了前瞻性研究。对于我们的日本参与者，男性的总跌倒发生率为139/1000人年，女性为276/1000人年。与我们的日本参与者相比，以白人为主的年龄调整后的跌倒率比率为女性的1.8至2.3，男性的2.6至4.7。但是，我们的日本参与者跌倒时受伤的风险并不比白人参与者低。对于我们的日本人口，过去的跌倒，女性性别和白天的时间与跌倒的发生率增加有关。

BACKGROUND & AIMS: :An inverse relationship between age and human papillomavirus (HPV) prevalence has been reported in many developed countries, but information on this relationship is scarce in many other parts of the world. We carried out a cross-sectional study of sexually active women from the general population of 15 areas in 4 continents. Similar standardised protocols for women's enrolment, cervical specimen collection and PCR-based assays for HPV testing were used. HPV prevalence in different age groups was compared by study area. 18,498 women aged 15-74 years were included. Age-standardised HPV prevalence varied more than 10-fold between populations, as did the shape of age-specific curves. HPV prevalence peaked below age 25 or 35, and declined with age in Italy, the Netherlands, Spain, Argentina, Korea and in Lampang, Thailand and Ho Chi Minh, Vietnam. This was not the case in Songkla, Thailand nor Hanoi, Vietnam, where HPV prevalence was low in all age groups. In Chile, Colombia and Mexico, a second peak of HPV prevalence was detected among older women. In the poorest study areas in Asia (Shanxi, China and Dindigul, India), and in Nigeria, HPV prevalence was high across all age groups. The substantial differences observed in age-specific curves of HPV prevalence between populations may have a variety of explanations. These differences, however, underline that great caution should be used in inferring the natural history of HPV from age-specific prevalences.

背景与目标： : 在许多发达国家，已经报道了年龄与人乳头瘤病毒 (HPV) 患病率之间的反比关系，但是在世界许多其他地区，有关这种关系的信息很少。我们对来自4大洲15个地区的普通人群的性活跃女性进行了横断面研究。使用了类似的标准化方案，用于女性入组，宫颈标本收集和基于PCR的HPV检测方法。按研究区域比较了不同年龄组的HPV患病率。包括18,498名15-74岁的妇女。年龄标准化的HPV患病率在人群之间的变化超过10倍，年龄特定曲线的形状也是如此。HPV的患病率在25岁或35岁以下达到峰值，在意大利，荷兰，西班牙，阿根廷，韩国以及泰国南邦和越南胡志明市，随着年龄的增长而下降。泰国宋卡和越南河内的情况都不是这样，那里所有年龄组的HPV患病率都很低。在智利，哥伦比亚和墨西哥，在老年妇女中发现了HPV患病率的第二个高峰。在亚洲最贫困的研究地区 (中国山西和印度Dindigul) 和尼日利亚，HPV的患病率在所有年龄组中都很高。在人群之间HPV患病率的年龄特异性曲线中观察到的实质性差异可能有多种解释。然而，这些差异强调，在从年龄特异性患病率推断HPV的自然史时应格外小心。

BACKGROUND & AIMS: PURPOSE:Consistent condom use is critical to efforts to prevent sexually transmitted infections among adolescents, but condom use may decline as relationships and contraceptive needs change. The purpose of this research is to assess changes in condom non-use longitudinally in the context of changes in relationship quality, coital frequency and hormonal contraceptive choice. METHODS:Participants were women (aged 14-17 years at enrollment) recruited from three urban adolescent medicine clinics. Data were collected at three-month intervals using a face-to-face structured interview. Participants were able to contribute up to 10 interviews, but on average contributed 4.2 interviews over the 27-month period. Independent variables assessed partner-specific relationship quality (five items; scale range 5-25; alpha = .92, e.g., this partner is a very important person to me); and, number of coital events with a specific partner. Additional items assessed experience with oral contraceptive pills (OCP) use and injected depo medroxy-progesterone acetate (DMPA). The outcome variable was number of coital events without condom use during the past three months. Analyses were conducted as a three-level hierarchical linear growth curve model using HLM 6. The Level 1 predictor was time, to test the hypothesis that condom non-use increases over time. Level 2 predictors assessed relationship quality and coital frequency across all partners to assess hypotheses that participants' condom non-use increases over time as a function of relationship quality and coital frequency. Level 3 predictors assessed the participant-level influence of OCP or DMPA experience on time-related changes in condom non-use. RESULTS:A total of 176 women reported 279 sex partners and contributed 478 visits. Both average coital frequency and average condom non-use linearly increased during the 27-month follow-up. At any given follow-up, about 35% reported recent OCP use, and 65% reported DMPA use. HLM analyses showed that condom non-use increased as a function of time (beta = .12; p = .03, Level 1 analysis). Increased condom non-use over time was primarily a function of increased coital frequency (beta = .01; p = .00), although higher levels of relationship quality were associated with increased condom non-use at enrollment (beta = .44; p = .00, Level 2 analysis). The temporal rise in condom non-use significantly increased among DMPA users (beta = .06; p = .00) but not OCP users (Level 3 analysis) (beta = -.04; p = .06). CONCLUSIONS:Developmentally, relationship characteristics and coital frequency appear to have increasing weight in decisions about condom use. Hormonal contraceptive methods are not equivalently associated with the overall temporal decline in condom use. Future research associated with dual contraceptive/condom use should address differential factors associated condom use in combination with different hormonal methods.

BACKGROUND & AIMS: The exact mechanism for the decrease in intestinal calcium absorption with age is not yet understood. A decrease with age in serum 1,25-dihydroxyvitamin D (1,25(OH)2D) or a decrease in the intestinal vitamin D receptor (VDR) protein concentration are possible causes. The objective of this study was to examine the effect of age on these factors. Fifty-nine young women age 25-35 years were compared with 41 elderly women age 65-83 years who underwent measurements of VDR, calcium absorption using a 20 mg and 100 mg calcium carrier, and calciotropic hormones. Calcium absorption by both tests was lower in the elderly women compared with the young women (p < 0.05). Serum 1,25(OH)2D and duodenal VDR protein concentration were not significantly different between the two age groups. Serum 1,25(OH)2D correlated with the 20 mg calcium absorption test in both young (r = 0.35, p < 0.007) and elderly women (r = 0.58, p < 0.0001) and with the 100 mg calcium absorption in the elderly (r = 0.32; p < 0.05). VDR did not correlate with calcium absorption in young women or elderly women, nor did VDR correlate with serum 1,25(OH)2D and serum 25-hydroxyvitamin D. In summary, the decrease in calcium absorption cannot be explained by a decrease in intestinal VDR. The correlation between serum 1,25(OH)2D and both calcium absorption tests only accounts for 12-30% of the variance in the age-related change in the calcium absorption tests. Other factors, not yet understood, are responsible for the decline in calcium absorption with age.

背景与目标： 随着年龄的增长，肠道钙吸收减少的确切机制尚不清楚。血清1,25-二羟基维生素d (1,25(OH)2D) 随着年龄的增长而降低或肠道维生素d受体 (VDR) 蛋白浓度降低是可能的原因。这项研究的目的是检查年龄对这些因素的影响。将59名年龄在25-35岁之间的年轻女性与41名年龄在65-83岁之间的老年女性进行了比较，这些女性接受了VDR，使用20 mg和100 mg钙载体的钙吸收以及钙促激素的测量。与年轻女性相比，老年女性两种测试对钙的吸收均较低 (p <0.05)。血清1,25(OH)2D和十二指肠VDR蛋白浓度在两个年龄组之间没有显着差异。血清1,25(OH)2D与青年 (r = 0.35，p <0.007) 和老年妇女 (r = 0.58，p <0.0001) 的20 mg钙吸收试验相关，与老年人的100 mg钙吸收相关 (r = 0.32; p <0.05)。VDR与年轻女性或老年女性的钙吸收无关，也与血清1,25(OH)2D和血清25-羟基维生素d无关。总而言之，钙吸收的减少不能用肠道VDR的减少来解释。血清1,25(OH)2D与两种钙吸收测试之间的相关性仅占钙吸收测试中年龄相关变化的12-30%。其他尚未了解的因素是钙吸收随年龄下降的原因。

BACKGROUND & AIMS: BACKGROUND:Choline is essential for fetal brain development, and it is not known whether a typical American diet contains enough choline to ensure optimal brain development. OBJECTIVE:The study was undertaken to determine whether supplementing pregnant women with phosphatidylcholine (the main dietary source of choline) improves the cognitive abilities of their offspring. DESIGN:In a double-blind, randomized controlled trial, 140 pregnant women were randomly assigned to receive supplemental phosphatidylcholine (750 mg) or a placebo (corn oil) from 18 wk gestation through 90 d postpartum. Their infants (n = 99) were tested for short-term visuospatial memory, long-term episodic memory, language development, and global development at 10 and 12 mo of age. RESULTS:The women studied ate diets that delivered ∼360 mg choline/d in foods (∼80% of the recommended intake for pregnant women, 65% of the recommended intake for lactating women). The phosphatidylcholine supplements were well tolerated. Groups did not differ significantly in global development, language development, short-term visuospatial memory, or long-term episodic memory. CONCLUSIONS:Phosphatidylcholine supplementation of pregnant women eating diets containing moderate amounts of choline did not enhance their infants' brain function. It is possible that a longer follow-up period would reveal late-emerging effects. Moreover, future studies should determine whether supplementing mothers eating diets much lower in choline content, such as those consumed in several low-income countries, would enhance infant brain development.

BACKGROUND & AIMS: :The effect of ascorbic acid on iron retention from a diet with predicted low iron bioavailability (containing minimal meat and ascorbic acid) was investigated in iron-depleted premenopausal women. Eleven women were depleted of storage iron (indicated by serum ferritin) through a combination of diet (5.0 mg Fe/2000 kcal for 67-88 d) and phlebotomy. They then consumed a diet containing 13.7 mg Fe/2000 kcal, supplemented with placebo or ascorbic acid three times daily (1500 mg total) with meals for 5.5 wk. Ascorbic acid improved apparent iron absorption (balance method) [38 +/- 2% (means +/- SEM) vs 27 +/- 2%]. Ascorbic acid also improved hemoglobin, erythrocyte protoporphyrins, and serum iron but not hematocrit, serum ferritin, iron-binding capacity, or transferrin saturation. In iron-depleted women consuming a diet with predicted poor iron availability, ascorbic acid supplementation enhanced body iron retention for 5.5 wk.

背景与目标： : 在铁缺乏的绝经前妇女中，研究了抗坏血酸对铁生物利用度较低 (含有最少的肉和抗坏血酸) 饮食中铁保留的影响。通过饮食 (5.0 mg Fe/2000 kcal，治疗67-88 d) 和放血术，11名妇女耗尽了储存铁 (由血清铁蛋白指示)。然后，他们食用含有13.7 mg Fe/2000 kcal的饮食，补充有安慰剂或抗坏血酸，每天三次 (总共1500 mg)，并进餐5.5周。抗坏血酸改善了铁的表观吸收 (平衡法) [38 +/- 2% (平均值 +/- SEM) 对27 +/- 2%]。抗坏血酸还可以改善血红蛋白，红细胞原卟啉和血清铁，但不能改善血细胞比容，血清铁蛋白，铁结合能力或转铁蛋白饱和度。在消耗铁的女性中，饮食中预计铁利用率较差，抗坏血酸补充剂可提高5.5周的体内铁保留率。

BACKGROUND & AIMS: BACKGROUND:Evidence-based guidelines recommend limited perioperative diagnostic imaging for new breast cancer diagnoses. For patients aged >65 years, conventional imaging use (mammography, plain radiographs, and ultrasound) has remained stable, whereas advanced imaging (computed tomography [CT], nuclear medicine scans [positron emission tomography/bone scans], and magnetic resonance imaging [MRI]) use has increased. In this study, the authors evaluated traditional and advanced imaging use among younger patients (aged ≤ 65 years) undergoing breast cancer surgery. METHODS:The MarketScan Commercial Claims and Encounters Research Database from 2005 through 2008 was analyzed to evaluate the use of conventional and advanced diagnostic imaging associated with surgery for ductal carcinoma in situ (DCIS) or stage I through III invasive breast cancer. RESULTS:The study cohort included 52,202 women (13% with DCIS and 87% with stage I-III breast cancer). The proportion of patients undergoing conventional imaging remained stable, whereas the average number of conventional imaging tests per patient increased from 4.21 tests in 2005 to 4.79 tests per patient in 2008 (P < .0001). For advanced imaging, the proportion of women who underwent imaging increased from 48.8% in 2005 to 68.8% in 2008 (P < .0001), as did the number of tests per patient (from 1.53 tests in 2005 to 1.98 tests in 2008; P < .0001). MRI examinations accounted for nearly all of the increase in advanced imaging. Patients who underwent MRI examinations received significantly more traditional imaging tests compared with to those who did not, indicating that these tests are additive and are not replacing traditional imaging. CONCLUSIONS:The current results demonstrate that the use of perioperative breast MRI has increased among women aged <65 years. Further study is indicated to determine whether the benefits of this procedure justify increased use.

BACKGROUND & AIMS: :Nut consumption is associated with a reduced risk of type 2 diabetes mellitus (T2DM). The aim of the present study was to assess the effects of adding peanuts (whole or peanut butter) on first (0-240 min)- and second (240-490 min)-meal glucose metabolism and selected gut satiety hormone responses, appetite ratings and food intake in obese women with high T2DM risk. A group of fifteen women participated in a randomised cross-over clinical trial in which 42·5 g of whole peanuts without skins (WP), peanut butter (PB) or no peanuts (control) were added to a 75 g available carbohydrate-matched breakfast meal. Postprandial concentrations (0-490 min) of glucose, insulin, NEFA, glucagon-like peptide-1 (GLP-1), peptide YY (PYY), cholecystokinin (CCK), appetitive sensations and food intake were assessed after breakfast treatments and a standard lunch. Postprandial NEFA incremental AUC (IAUC) (0-240 min) and glucose IAUC (240-490 min) responses were lower for the PB breakfast compared with the control breakfast. Insulin concentrations were higher at 120 and 370 min after the PB consumption than after the control consumption. Desire-to-eat ratings were lower, while PYY, GLP-1 and CCK concentrations were higher after the PB intake compared with the control intake. WP led to similar but non-significant effects. The addition of PB to breakfast moderated postprandial glucose and NEFA concentrations, enhanced gut satiety hormone secretion and reduced the desire to eat. The greater bioaccessibility of the lipid component in PB is probably responsible for the observed incremental post-ingestive responses between the nut forms. Inclusion of PB, and probably WP, to breakfast may help to moderate glucose concentrations and appetite in obese women.

背景与目标： : 食用坚果与降低2型糖尿病 (T2DM) 的风险相关。本研究的目的是评估添加花生 (全或花生酱) 对第一 (0-240分钟) 和第二 (240-490分钟) 膳食葡萄糖代谢和选定的肠道饱腹激素反应的影响，高T2DM风险肥胖女性的食欲等级和食物摄入。一组15名妇女参加了一项随机交叉临床试验，其中将42·5克不含皮 (WP)，花生酱 (PB) 或无花生 (对照) 的全花生添加到75克可用的碳水化合物匹配早餐中。在早餐治疗和标准午餐后，评估餐后葡萄糖，胰岛素，NEFA，胰高血糖素样肽-1 (GLP-1)，肽YY (PYY)，胆囊收缩素 (CCK)，食欲感和食物摄入量的浓度 (0-490分钟)。与对照早餐相比，PB早餐的餐后NEFA增量AUC (IAUC) (0-240分钟) 和葡萄糖IAUC (240-490分钟) 响应较低。PB消耗后120和370分钟的胰岛素浓度高于对照消耗后的胰岛素浓度。与对照摄入量相比，摄入PB后的饮食欲望等级较低，而PYY，GLP-1和CCK浓度较高。WP导致了类似但不显著的影响。早餐中添加PB可降低餐后葡萄糖和NEFA的浓度，增强肠道饱腹激素的分泌并降低进食欲望。PB中脂质成分的更大的生物可及性可能是观察到的坚果形式之间摄入后的增量反应的原因。在早餐中加入PB (可能是WP) 可能有助于减轻肥胖女性的葡萄糖浓度和食欲。

BACKGROUND & AIMS: OBJECTIVE:Breast-feeding is associated with maternal health, such as electrolyte metabolism, lipid profile and body component change. The aim of this study was to evaluate the relationship between duration of breast-feeding and obesity in postmenopausal women. METHODS:We analyzed data from the Korea National Health and Nutrition Examination Survey (KNHANES) 2010-2012, a cross-sectional study in a Korean population. A total of 6621 postmenopausal women were analyzed. RESULTS:Body mass index and waist circumference were greater in women who had breast-fed for 6 months or more than in those who had not (BMI: 23.7±0.1 vs 24.5±0.1, P<0.0001; WC: 80.6±0.4 vs 82.8±0.3, P<0.001). This association persisted after adjustment for confounding factors (BMI: odds ratio[OR]1.54, 95% confidence interval[CI] 1.19-2.0; WC: OR1.67, 95% CI 1.29-2.17). The duration of breast-feeding tended to increase with increasing BMI and WC (P for trend, 0.001 for each). The proportions of women with greater BMI and WC increased with increasing duration of breast-feeding (27.3% in ≤6 months vs 41.2% in >18months, P<0.0001). CONCLUSION:The results of this study suggest that prolonged breast-feeding may be associated with greater BMI and WC among postmenopausal women.

BACKGROUND & AIMS: PURPOSE:Many women with hormone receptor-positive breast cancer discontinue effective aromatase inhibitor (AI) treatment due to joint symptoms. METHODS:We conducted a single-arm, open-label, phase II study evaluating glucosamine-sulfate (1,500 mg/day) + chondroitin-sulfate (1,200 mg/day) for 24 weeks to treat joint pain/stiffness in postmenopausal women with early stage breast cancer who developed moderate-to-severe joint pain after initiating AIs. The primary endpoint was improvement in pain/stiffness at week 24 assessed by the Outcome Measure in Rheumatology Clinical Trials and Osteoarthritis Research Society International (OMERACT-OARSI) criteria. Secondary endpoints assessed changes in pain, stiffness, and function using the Western Ontario and McMaster Universities Osteoarthritis (WOMAC) Index for hips/knees and the Modified Score for the Assessment and Quantification of Chronic Rheumatoid Affections of the Hands (M-SACRAH) for hands/wrists. The Brief Pain Inventory (BPI) assessed pain interference, severity, and worst pain. RESULTS:Of 53 patients enrolled, 39 were evaluable at week 24. From baseline to week 24, 46 % of patients improved according to OMERACT-OARSI criteria. At week 24, there were improvements (all P < 0.05) in pain and function as assessed by WOMAC and M-SACRAH, and in pain interference, severity, and worst pain as assessed by BPI. Estradiol levels did not change from baseline. The most commonly reported side effects were headache (28 %), dyspepsia (15 %), and nausea (17 %). CONCLUSIONS:In this single-arm study, 24 weeks of glucosamine/chondroitin resulted in moderate improvements in AI-induced arthralgias, with minimal side effects, and no changes in estradiol levels. These results suggest a need to evaluate efficacy in a placebo-controlled trial.

BACKGROUND & AIMS: OBJECTIVE:The aim was to investigate birth characteristics, obstetric and neonatal outcomes of the first childbirth in women with Marfan syndrome by use of Swedish national registers since pregnancy-related outcomes in women with Marfan syndrome have only been sparsely investigated. STUDY DESIGN:In this national population-based cohort study and matched case-control study of Swedish women born 1973-1993, women with Marfan syndrome (n=273) were compared to women without the condition (n=1 017 265). The study population was followed until 2013. A total of 364 553 mother-firstborn-offspring pairs were analyzed. Sixty-one women with Marfan syndrome became mothers. Women with Marfan syndrome were also compared to 543 healthy controls. RESULTS:Women with Marfan syndrome were more often born preterm (p<0.001), small-for-gestational age (p<0.001), and delivered by cesarean section (p=0.001). Women with Marfan syndrome had no increased risk of giving birth by cesarean section (p=0.079). No increased neonatal risks in their children were found. Women with Marfan syndrome were less likely to give birth than those without (p<0.001). There were no maternal deaths. CONCLUSIONS:Women with Marfan syndrome were more likely to be born preterm, SGA and by cesarean section. These increased risks of preterm birth and SGA babies were not found in connection with their own first childbirth. Pregnancies with known fetal Marfan syndrome have to be carefully monitored. The results are important for obstetricians giving preconception counseling and treating women with Marfan syndrome. Further studies are needed to evaluate risks during pregnancy and long-term effects of pregnancy on the cardiovascular status of women with Marfan syndrome.

BACKGROUND & AIMS: :In a previous study it was shown that lower factor XI (FXI) levels in women with heavy menstrual bleeding (HMB). Our aim was to determine the single-nucleotide variants (SNVs) in the F11 gene in women with HMB. In addition, an extensive literature search was performed to determine the clinical significance of each SNV. Patients referred for HMB (PBAC-score >100) were included. With direct sequencing analysis of all 15 exons and flanking introns of the F11 gene, 29 different non-structural SNVs were detected in 49 patients with HMB. Interestingly, most of these SNVs have previously been associated with venous thrombosis instead of bleeding. These findings have not helped to elucidate the molecular basis of HMB. They also question the specificity of previously reported F11 variations in patients with thrombosis. More studies are needed to explain the lower FXI levels seen in patients with HMB. IMPACT STATEMENT Women with mild deficiencies of factor XI (FXI) (< 70%) are prone to excessive bleeding during menstruation. Bleeding manifestations are not well correlated with plasma FXI levels and bleeding episodes can vary widely among patients with similar low FXI levels. In a previous study we showed that women with heavy menstrual bleeding (HMB) had normal, but on average, lower levels of FXI than controls. In light of these findings, we performed F11 gene analysis to determine the single-nucleotide variants (SNVs) in women with HMB and performed an extensive literature search to determine the clinical significance of each SNV. By direct sequencing analysis of the F11 gene we found 29 different non-structural SNVs in 49 women with heavy menstrual bleeding. Remarkably, a number of these SNVs have previously been implicated in thrombosis. These findings have not helped to elucidate the molecular basis of lower FXI levels in HMB. They also question the specificity of previously reported F11 variations in patients with thrombosis. More studies are needed to explain the lower FXI levels seen in patients with HMB.

背景与目标： : 在先前的研究中，显示月经大量出血 (HMB) 女性的因子XI (FXI) 水平较低。我们的目的是确定HMB女性F11基因中的单核苷酸变体 (snv)。此外，还进行了广泛的文献检索，以确定每种SNV的临床意义。纳入HMB转诊的患者 (PBAC评分> 100)。通过对F11基因的所有15个外显子和侧翼内含子的直接测序分析，在49例HMB患者中检测到29种不同的非结构性snv。有趣的是，这些snv中的大多数以前都与静脉血栓形成有关，而不是出血。这些发现无助于阐明HMB的分子基础。他们还质疑先前报道的F11变异在血栓形成患者中的特异性。需要更多的研究来解释HMB患者中较低的FXI水平。影响声明轻度缺乏因子XI (FXI) (<  70%) 的女性在月经期间容易出血过多。出血表现与血浆FXI水平没有很好的相关性，在FXI水平相似的患者中，出血发作可能有很大差异。在先前的研究中，我们表明，月经大量出血 (HMB) 的女性FXI水平正常，但平均而言，低于对照组。根据这些发现，我们进行了F11基因分析以确定HMB女性的单核苷酸变异体 (SNV)，并进行了广泛的文献检索以确定每种SNV的临床意义。通过对F11基因的直接测序分析，我们在49名月经大量出血的女性中发现了29种不同的非结构性snv。值得注意的是，这些snv中的许多以前都与血栓形成有关。这些发现无助于阐明HMB中FXI水平较低的分子基础。他们还质疑先前报道的F11变异在血栓形成患者中的特异性。需要更多的研究来解释HMB患者中较低的FXI水平。

BACKGROUND & AIMS: :We explored the attitudes of women at midlife to web-based interventions for promoting physical activity. 145 women volunteered to participate in one of four online forums. The forums were for four major racial/ethnic groups. 90 volunteers were recruited for the online forums (29 Whites, 23 Hispanics, 21 African Americans, and 17 Asians). Two sets of topics on attitudes to physical activity and racial/ethnic contexts were used. Each topic had some introductory questions and related prompts, and these were posted on the online forum sites in a serial fashion during the six-month period. We used a thematic analysis. Four major themes emerged: (1) 'a matter of the source of the information'; (2) 'I can pace myself'; (3) 'lack of interpersonal interactions'; and (4) 'culture-specificity and low cost.' The women in all ethnic groups thought that the source of the information was much more important than the medium of the information (e.g. web-based, booklet or face-to-face). They liked the self-controllability in web-based interventions. They preferred web-based interventions to other types of interventions because of easy accessibility, but they were concerned about lack of interpersonal interaction. None of the White or African American women indicated the need for culture-specificity in web-based interventions, but Hispanic and Asian women indicated that culture-specific interventions should be provided. Web-based interventions appear to have several advantages over conventional approaches to promoting physical activity.

背景与目标： : 我们探讨了中年妇女对基于网络的干预措施以促进体育锻炼的态度。145妇女自愿参加四个在线论坛之一。论坛面向四个主要种族/族裔群体。在线论坛招募了90名志愿者 (29名白人，23名西班牙裔，21名非裔美国人和17名亚洲人)。使用了两套关于体育活动态度和种族/族裔背景的主题。每个主题都有一些介绍性问题和相关提示，这些问题在六个月内以连续方式发布在在线论坛网站上。我们使用了主题分析。出现了四个主要主题 :( 1) “信息来源问题”; (2) “我可以调整自己”; (3) “缺乏人际互动”; (4) “文化特殊性和低成本”。所有种族的妇女都认为信息的来源比信息的媒介 (例如基于网络的，小册子或面对面的) 重要得多。他们喜欢基于网络的干预中的自我控制性。由于易于访问，他们更喜欢基于网络的干预措施，而不是其他类型的干预措施，但他们担心缺乏人际互动。在基于网络的干预措施中，没有白人或非洲裔美国妇女表示需要文化特异性，但是西班牙裔和亚裔妇女表示应提供针对文化的干预措施。与传统的促进体育锻炼的方法相比，基于网络的干预似乎具有几个优势。

BACKGROUND & AIMS: :Menopausal hormone treatment (MHT) may limit progression of cardiovascular disease (CVD) but poses a thrombosis risk. To test targeted candidate gene variation for association with subclinical CVD defined by carotid artery intima-media thickness (CIMT) and coronary artery calcification (CAC), 610 women participating in the Kronos Early Estrogen Prevention Study (KEEPS), a clinical trial of MHT to prevent progression of CVD, were genotyped for 13,229 single nucleotide polymorphisms (SNPs) within 764 genes from anticoagulant, procoagulant, fibrinolytic, or innate immunity pathways. According to linear regression, proportion of European ancestry correlated negatively, but age at enrollment and pulse pressure correlated positively with CIMT. Adjusting for these variables, two SNPs, one on chromosome 2 for MAP4K4 gene (rs2236935, β = 0.037, P value = 2.36 × 10(-06)) and one on chromosome 5 for IL5 gene (rs739318, β = 0.051, P value = 5.02 × 10(-05)), associated positively with CIMT; two SNPs on chromosome 17 for CCL5 (rs4796119, β = -0.043, P value = 3.59 × 10(-05); rs2291299, β = -0.032, P value = 5.59 × 10(-05)) correlated negatively with CIMT; only rs2236935 remained significant after correcting for multiple testing. Using logistic regression, when we adjusted for waist circumference, two SNPs (rs11465886, IRAK2, chromosome 3, OR = 3.91, P value = 1.10 × 10(-04); and rs17751769, SERPINA1, chromosome 14, OR = 1.96, P value = 2.42 × 10(-04)) associated positively with a CAC score of >0 Agatston unit; one SNP (rs630014, ABO, OR = 0.51, P value = 2.51 × 10(-04)) associated negatively; none remained significant after correcting for multiple testing. Whether these SNPs associate with CIMT and CAC in women randomized to MHT remains to be determined.

背景与目标： : 更年期激素治疗 (MHT) 可能会限制心血管疾病 (CVD) 的进展，但会带来血栓形成的风险。为了测试与颈动脉内膜中层厚度 (CIMT) 和冠状动脉钙化 (CAC) 定义的亚临床CVD相关的靶向候选基因变异，610参加Kronos早期雌激素预防研究 (KEEPS) 的妇女，MHT预防CVD进展的临床试验，在抗凝剂，促凝剂，纤溶或先天免疫途径的764基因内对13,229单核苷酸多态性 (snp) 进行基因分型。根据线性回归，欧洲血统的比例呈负相关，但入学年龄和脉压与CIMT呈正相关。调整这些变量，两个snp，一个在2号染色体上的MAP4K4基因 (rs2236935，β = 0.037，p值 = 2.36 × 10(-06))，一个在5号染色体上的IL5基因 (rs739318，β = 0.051，p值 = 5.02 × 10(-05))，与CIMT呈正相关; CCL5 17号染色体上的两个snp (rs4796119，β = -0.043，p值 = 3.59 × 10(-05); rs2291299，β = -0.032，p值 = 5.59 × 10(-05)) 与CIMT呈负相关; 校正多重测试后，只有rs2236935仍然显著。使用逻辑回归，当我们调整腰围时，两个snp (rs11465886，IRAK2，3号染色体，OR = 3.91，p值 = 1.10 × 10(-04); 和rs17751769，SERPINA1，14号染色体，OR = 1.96，p值 = 2.42 × 10(-04)) 与> 0 Agatston单位的CAC评分呈正相关; 1个SNP (rs630014，ABO，OR = 0.51，p值 = 2.51 × 10(-04)) 呈负相关; 校正多重测试后无显著。这些snp是否与CIMT和CAC相关，在随机分配到MHT的女性中仍有待确定。

BACKGROUND & AIMS: :Screening programs can reduce the burden of disease, however, they can be associated with raised levels of anxiety. The risk of endometrial and ovarian cancer is increased in hereditary nonpolyposis colorectal cancer (HNPCC). There is no prospective evidence to support screening for gynecological disease in HNPCC, however, current recommendations include the use of ultrasound and endometrial biopsy. This study assesses the impact of screening for gynecological cancer on self-reported symptoms of anxiety, depression, and perceptions of health. Women from HNPCC families attending gynecological screening (n = 26) completed the Hospital Anxiety and Depression Scale and the ShortForm36v2 questionnaires prior to screening with transvaginal ultrasound, outpatient/office hysteroscopy, endometrial biopsy, and ovarian tumor marker assessment (CA125). The same questionnaires were completed at 3 and 6 months following screening (15/26). Women in HNPCC families attending for gynecological screening did not have excess symptoms of anxiety or depression at baseline in subjective comparison to other populations. The process of screening and false positive screening results had no significant impact on symptoms of anxiety and depression or perceptions of health. We conclude that within the limitations of analysis in this small study group, screening for gynecological disease in HNPCC does not appear to be associated with any psychological morbidity.

背景与目标： : 筛查计划可以减轻疾病负担，但是，它们可能与焦虑水平升高有关。遗传性非息肉病性结直肠癌 (HNPCC) 发生子宫内膜癌和卵巢癌的风险增加。目前尚无前瞻性证据支持在HNPCC中筛查妇科疾病，但是，目前的建议包括使用超声和子宫内膜活检。这项研究评估了筛查妇科癌症对自我报告的焦虑，抑郁和健康观念的影响。来自HNPCC家庭的女性 (n = 26) 在接受经阴道超声，门诊/办公室宫腔镜检查，子宫内膜活检和卵巢肿瘤标志物评估 (CA125) 进行筛查之前，完成了医院焦虑和抑郁量表和ShortForm36v2问卷。在筛选后的3个月和6个月 (15/26) 完成相同的问卷。与其他人群相比，参加妇科筛查的HNPCC家庭中的女性在基线时没有过度的焦虑或抑郁症状。筛查过程和假阳性筛查结果对焦虑抑郁症状或健康感知无显著影响。我们得出的结论是，在这个小型研究组的分析局限性内，在HNPCC中筛查妇科疾病似乎与任何心理疾病无关。
