BackgroundMetabolic syndrome (MetS) is related to the increased risk of major cardiovascular diseases (CVD). The link between high serum total bilirubin (TBL) is cross-sectionally related to MetS and its components. However, whether serum TBL predicts incidence of MetS and its components remains inconclusive.MethodsThe present study included 893 women aged 70 ± 9 years from a rural village. We examined the relationship between serum TBL and MetS based on the modified criteria of the National Cholesterol Education Program's Adult Treatment Panel (NCEP-ATP) III report in a cross-sectional (N = 893) and cohort (N = 288) data.ResultsIn the cross-sectional study, serum TBL (β = 0.536, p < 0.001) as well as age, alcohol consumption, exercise habits, history of CVD, SUA, GGT, and ALT was significantly and dependently associated with number of MetS components, but in the cohort study serum TBL was not associated with number of MetS components. Compared with the 1st tertile of serum TBL (0.20–0.55 mg/dL), multivariate-adjusted odds ratio (95% confidence interval) for the 2nd -3rd tertiles of serum TBL (0.54–2.00 mg/dL) was 0.70 (0.51–0.95) in the cross-sectional study and 0.41 (0.21–0.81) in the cohort study.ConclusionsOur data demonstrated an independently negative association between serum TBL and MetS in Japanese community-dwelling women.  相似文献

Setting and objectiveIn Italy, over the last decades, elderly care has been mostly provided by family members, especially adult offspring, and in particular daughters. This paper investigates the relationship between informal caregiving and mental distress among Italians aged 35–59, with a focus on gender effect and parenthood responsibilities.DataThe dataset is the European Health Interview Survey (EHIS), second wave, year 2015. As far as it is known, the Italian EHIS has not been used for studies on ageing and caregiving.MethodsUsing selected subsamples, a Propensity Score Matching between caregivers and non-caregivers aged 35–59 is implemented, with the aim of measuring the difference in level of depression, if any, between the two groups.ResultsFindings show that women providing their frail relatives with informal care are less likely to suffer from mental distress compared to non-carers. However, results change radically if they have children aged less than 15 at home, and a higher probability of being depressed is detected for women overwhelmed by the double responsibility of assisting both dependent relatives and their own children. Results are not significant for men.  相似文献

IntroductionObesity can lead to pelvic floor disorders, interfering with women’s sexual life; Prolapse/Incontinence Sexual Questionnaire-International Urogynecology Association–Revised (PISQ-IR) is a new instrument to measure sexual life in women with pelvic floor disorders.AimsTo assess the utility of using PISQ-IR in morbidly obese women undergoing bariatric surgery and to show the improvement of bariatric surgery on sexuality.MethodsThis prospective monocentric study included all women who underwent bariatric surgery from June 2016–May 2017. Sleeve gastrectomy (SG) or Roux-en-Y gastric bypass (RYGB) was performed by 1 surgeon, and data were collected by 1 researcher. Demographics, medical history, number of deliveries, and type of bariatric surgery (SG or RYGB) were collected at baseline. At the 1-year follow-up consultation, postoperative complications, percentage of total body weight loss (TWL) and percentage excess weight loss were assessed. Questionnaires were given at baseline and at 1-year follow-up.Main Outcome MeasuresPostoperative complications and total weight loss were measured at the 1-year follow-up. Sexual activity, using the PISQ-IR, and pelvic organ prolapse, urinary incontinence, and anal incontinence, using the urinary symptom profile and PFDI (Pelvic Floor Distress Inventory) 20, were compared before surgery and at 1-year follow-up.Results72 patients were included at baseline, 54 (75%) were considered for final analysis (30 RYGB and 24 SG), and 51 patients were considered for PISQ-IR. The mean preoperative body mass index was 41 ± 5.4 kg/m2, and mean age was 43 ± 11.8 years. Both procedures induced an important weight loss (mean TWL of 33%) and had a similar percentage of TWL for each procedure: 31 (15–46) for SG vs 34 (9–51) for RYGB. 9 patients (17 [6%]) became sexually active 1 year after surgery. For the sexually inactive population after 1 year, there was no differences in the PISQ-IR in the follow-up. When body mass index loss was >13 kg/m2, a higher percentage of the sexually active population improved their different scores, and there were significant results for both global quality of life and desire (P = .026 and .046). The other questionnaires showed a significant decrease in urinary incontinence symptoms (P < .001) associated with weight loss, whereas there was no difference in terms of pelvic organ prolapse or anal incontinence.ConclusionPISQ-IR is a useful instrument to measure sexual function regarding pelvic floor disorders. Bariatric surgery improves sexual activity in obese women 1 year after surgery.Treacy PJ, Mazoyer C, Falagario U, et al.

More than thirty years have passed since sex and gender differences were noted in the age of onset, course and outcomes for schizophrenia. The ‘estrogen hypothesis” was coined in the 1990′s to describe neuroprotective effects of estrogen.Intervention studies in schizophrenia patients with estradiol and selective estrogen receptor modulators (SERMs) are promising but psychiatrists and other health practitioners do not generally take up this useful adjunctive treatment for their female patients with schizophrenia. The reasons for this are manifold, but overall a cultural shift in the practice of psychiatry is needed to recognise the specific needs of women with schizophrenia and tailor treatments, such as hormone adjuncts to improve the outcomes for this significant population.The two main aims of this article are to review the evidence and theory of estrogen treatments in schizophrenia and to recommend translation of adjunctive estrogen treatment into clinical practice for women with schizophrenia.  相似文献
