BACKGROUND: Polycystic ovarian syndrome (PCOS) is characterised by the clinical signs of oligo‐amenorrhoea, infertility and hirsutism. Conventional treatment of PCOS includes a range of oral pharmacological agents, lifestyle changes and surgical modalities. Beta‐endorphin is present in the follicular fluid of both normal and polycystic ovaries. It was demonstrated that the beta‐endorphin levels in ovarian follicular fluid of otherwise healthy women who were undergoing ovulation were much higher than the levels measured in plasma. Given that acupuncture impacts on beta‐endorphin production, which may affect gonadotropin‐releasing hormone (GnRH) secretion, it is postulated that acupuncture may have a role in ovulation induction via increased beta‐endorphin production effecting GnRH secretion. This is an update of our previous review published in 2016. OBJECTIVES: To assess the effectiveness and safety of acupuncture treatment for oligo/anovulatory women with polycystic ovarian syndrome (PCOS) for both fertility and symptom control. SEARCH METHODS: We identified relevant studies from databases including the Gynaecology and Fertility Group Specialised Register, CENTRAL, MEDLINE, Embase, PsycINFO, CNKI, CBM and VIP. We also searched trial registries and reference lists from relevant papers. CENTRAL, MEDLINE, Embase, PsycINFO, CNKI and VIP searches are current to May 2018. CBM database search is to November 2015. SELECTION CRITERIA: We included randomised controlled trials (RCTs) that studied the efficacy of acupuncture treatment for oligo/anovulatory women with PCOS. We excluded quasi‐ or pseudo‐RCTs. DATA COLLECTION AND ANALYSIS: Two review authors independently selected the studies, extracted data and assessed risk of bias. We calculated risk ratios (RR), mean difference (MD), standardised mean difference (SMD) and 95% confidence intervals (CIs). Primary outcomes were live birth rate, multiple pregnancy rate and ovulation rate, and secondary outcomes were clinical pregnancy rate, restored regular menstruation period, miscarriage rate and adverse events. We assessed the quality of the evidence using GRADE methods. MAIN RESULTS: We included eight RCTs with 1546 women. Five RCTs were included in our previous review and three new RCTs were added in this update of the review. They compared true acupuncture versus sham acupuncture (three RCTs), true acupuncture versus relaxation (one RCT), true acupuncture versus clomiphene (one RCT), low‐frequency electroacupuncture versus physical exercise or no intervention (one RCT) and true acupuncture versus Diane‐35 (two RCTs). Studies that compared true acupuncture versus Diane‐35 did not measure fertility outcomes as they were focused on symptom control. Seven of the studies were at high risk of bias in at least one domain. For true acupuncture versus sham acupuncture, we could not exclude clinically relevant differences in live birth (RR 0.97, 95% CI 0.76 to 1.24; 1 RCT, 926 women; low‐quality evidence); multiple pregnancy rate (RR 0.89, 95% CI 0.33 to 2.45; 1 RCT, 926 women; low‐quality evidence); ovulation rate (SMD 0.02, 95% CI –0.15 to 0.19, I(2) = 0%; 2 RCTs, 1010 women; low‐quality evidence); clinical pregnancy rate (RR 1.03, 95% CI 0.82 to 1.29; I(2) = 0%; 3 RCTs, 1117 women; low‐quality evidence) and miscarriage rate (RR 1.10, 95% CI 0.77 to 1.56; 1 RCT, 926 women; low‐quality evidence). Number of intermenstrual days may have improved in participants receiving true acupuncture compared to sham acupuncture (MD –312.09 days, 95% CI –344.59 to –279.59; 1 RCT, 141 women; low‐quality evidence). True acupuncture probably worsens adverse events compared to sham acupuncture (RR 1.16, 95% CI 1.02 to 1.31; I(2) = 0%; 3 RCTs, 1230 women; moderate‐quality evidence). No studies reported data on live birth rate and multiple pregnancy rate for the other comparisons: physical exercise or no intervention, relaxation and clomiphene. Studies including Diane‐35 did not measure fertility outcomes. We were uncertain whether acupuncture improved ovulation rate (measured by ultrasound three months post treatment) compared to relaxation (MD 0.35, 95% CI 0.14 to 0.56; 1 RCT, 28 women; very low‐quality evidence) or Diane‐35 (RR 1.45, 95% CI 0.87 to 2.42; 1 RCT, 58 women; very low‐quality evidence). Overall evidence ranged from very low quality to moderate quality. The main limitations were failure to report important clinical outcomes and very serious imprecision. AUTHORS' CONCLUSIONS: For true acupuncture versus sham acupuncture we cannot exclude clinically relevant differences in live birth rate, multiple pregnancy rate, ovulation rate, clinical pregnancy rate or miscarriage. Number of intermenstrual days may improve in participants receiving true acupuncture compared to sham acupuncture. True acupuncture probably worsens adverse events compared to sham acupuncture. No studies reported data on live birth rate and multiple pregnancy rate for the other comparisons: physical exercise or no intervention, relaxation and clomiphene. Studies including Diane‐35 did not measure fertility outcomes as the women in these trials did not seek fertility. We are uncertain whether acupuncture improves ovulation rate (measured by ultrasound three months post treatment) compared to relaxation or Diane‐35. The other comparisons did not report on this outcome. Adverse events were recorded in the acupuncture group for the comparisons physical exercise or no intervention, clomiphene and Diane‐35. These included dizziness, nausea and subcutaneous haematoma. Evidence was very low quality with very wide CIs and very low event rates. There are only a limited number of RCTs in this area, limiting our ability to determine effectiveness of acupuncture for PCOS.

Background End-stage kidney disease (ESKD) is a chronic, debilitative and progressive illness that may need interventions such as dialysis, transplantation, dietary and fluid restrictions. Most patients with ESKD will require renal replacement therapy, such as kidney transplantation or maintenance dialysis. Advance care planning traditionally encompass instructions via living wills, and concern patient preferences about interventions such as cardiopulmonary resuscitation and feeding tubes, or circumstances around assigning surrogate decision makers. Most people undergoing haemodialysis are not aware of advance care planning and few patients formalise their wishes as advance directives and of those who do, many do not discuss their decisions with a physician. Advance care planning involves planning for future healthcare decisions and preferences of the patient in advance while comprehension is intact. It is an essential part of good palliative care that likely improves the lives and deaths of haemodialysis patients. Objectives The objective of this review was to determine whether advance care planning in haemodialysis patients, compared with no or less structured forms of advance care planning, can result in fewer hospital admissions or less use of treatments with life-prolonging or curative intent, and if patient's wishes were followed at end-of-life. Search methods We searched the Cochrane Kidney and Transplant Specialised Register to 27 June 2016 through contact with the Information Specialist using search terms relevant to this review. We also searched the Cumulative Index of Nursing and Allied Health Literature (CINAHL), and Social Work Abstracts (OvidSP). Selection criteria All randomised controlled trials (RCTs) and quasi-RCTs (RCTs in which allocation to treatment was obtained by alternation, use of alternate medical records, date of birth or other predictable methods) looking at advance care planning versus no form of advance care planning in haemodialysis patients was considered for inclusion without language restriction. Data collection and analysis Data extraction was carried out independently by two authors using standard data extraction forms. Studies reported in non-English language journals were translated before assessment. Where more than one publication of one study exists, reports were grouped together and the publication with the most complete data was used in the analyses. Where relevant outcomes are only published in earlier versions these data were used. Any discrepancies between published versions were highlighted. Non-randomised controlled studies were excluded. Main results We included two studies (three reports) that involved 337 participants which investigated advance care planning for people with ESKD. Neither of the included studies reported outcomes relevant to this review. Study quality was assessed as suboptimal. Authors' conclusions We found sparse data that were assessed at suboptimal quality and therefore we were unable to formulate conclusions about whether advance care planning can influence numbers of hospital admissions and treatment required by people with ESKD, or if patients' advance care directives were followed at end-of-life. Further well designed and adequately powered RCTs are needed to better inform patient and clinical decision-making about advance care planning and advance directives among people with ESKD who are undergoing dialysis.

Background Historically, oestrogen and progesterone were each commonly used to save threatened pregnancies. In the 1940s it was postulated that their combined use would be synergistic and thereby led to the rationale of combined therapy for women who risked miscarriage. Objectives To determine the efficacy and safety of combined oestrogen and progesterone therapy to prevent miscarriage. Search methods We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (23 June 2013) CENTRAL (OVID) (The Cochrane Library 2013, Issue 6 of 12), MEDLINE (OVID) (1946 to June Week 2 2013), OLDMEDLINE (1946 to 1965), Embase (1974 to Week 25 2013), Embase Classic (1947 to 1973), CINAHL (1994 to 23 June 2013) and reference lists of retrieved studies. Selection criteria We included randomised controlled trials that assessed the effectiveness of combined oestrogen and progesterone for preventing miscarriage. We included one stratified randomised trial and one quasi-randomised trials. Cluster-randomised trials were eligible for inclusion but none were identified. We excluded studies published only as abstracts. We included studies that compared oestrogen and progesterone versus placebo or no intervention. Data collection and analysis Two review authors independently assessed trials for inclusion and assessed trial quality. Two review authors extracted data. Data were checked for accuracy. Main results Two trials (281 pregnancies and 282 fetuses) met our inclusion criteria. However, the two trials had significant clinical and methodological heterogeneity such that a meta-analysis combining trial data was considered inappropriate. One trial (involving 161 pregnancies) was based on women with a history of diabetes. It showed no statistically significant difference between using combined oestrogen and progestogen and using placebo for all our proposed primary outcomes, namely, miscarriage (risk ratio (RR) 0.95, 95% confidence interval (CI) 0.32 to 2.80), perinatal death (RR 0.94, 95% CI 0.53 to 1.69) and preterm birth (less than 34 weeks of gestation) (RR 0.91, 95% CI 0.80 to 1.04). In terms of this review's secondary outcomes, use of combined oestrogen and progestogen was associated with an increased risk of maternal cancer in the reproductive system (RR 6.65, 95% CI 1.56 to 28.29). However, for the outcome of cancer other than that of the reproductive system in mothers, there was no difference between groups. Similarly, there were no differences between the combined oestrogen and progestogen group versus placebo for other secondary outcomes reported: low birthweight of less than 2500 g, genital abnormalities in the offspring, abnormalities other than genital tract in the offspring, cancer in the reproductive system in the offspring, or cancer other than of the reproductive system in the offspring. The second study was based on pregnant women who had undergone in-vitro fertilisation (IVF). This study showed no difference in the rate of miscarriage between the combined oestrogen and progesterone group and the no treatment group (RR 0.66, 95% CI 0.23 to 1.85). The study did not report on this review's other primary outcomes (perinatal death or rates of preterm birth), nor on any of our proposed secondary outcomes. Authors' conclusions There is an insufficient evidence from randomised controlled trials to assess the use of combined oestrogen and progesterone for preventing miscarriages. We strongly recommend further research in this area.

The antenatal shared care model has become increasingly popular among Australian women as the preferred mode of pregnancy care. General practitioners are often asked by their pregnant women patients about the nutrients needed during pregnancy.This article discusses the role of various micronutrients and trace elements needed in pregnancy, and provides daily intake recommendations of these nutrients as a reference point.Much attention has been given to micronutrients such as folate and iron, but less regard to other trace elements that are also important in pregnancy. Encouraging a balanced diet and ensuring the adequacy of these micronutrients is essential for minimising pregnancy complications. However, GPs should also be aware of the maximum level of recommended intakes and any possible adverse effects.

The objective of this study is to review the existing scientific evidence on the potential role of acupuncture on induction of labor during pregnancy.The Medline, EMBASE, Cochrane Central Register of Controlled Trials, AMED (Allied and Complementary Medicine), and NCCAM (The National Center for Complementary and Alternative Medicine) databases were searched to identify relevant monographs from 1970 to 2008.These criteria included all available human acupuncture studies on pregnant women carrying a viable fetus due for third trimester induction of labor.These criteria included studies not meeting the inclusion criteria, in languages other than English, or animal studies.Ten (10) studies on labor induction were identified. The duration of labor as a result of acupuncture treatment ranged from 10 hours 20 minutes to 29.1 hours. All of the studies demonstrated labor induction by acupuncture treatment. However, because two randomized controlled trials reported that there was no statistically significant effect of acupuncture, these results are more suggestive than definitive. Furthermore, although the relationship between cervical ripening and interleukin-8 (IL-8), prostaglandin F(2alpha) (PGF(2alpha)), and beta-endorphin is well documented in the literature, there is no evidence to suggest that acupuncture alters these mediators. Serum levels of IL8, beta-endorphin, and PGF(2alpha) were not found to be significantly influenced by acupuncture.Although the definitive role of acupuncture in inducing labor is still yet to be established, the existing studies suggest that acupuncture may be beneficial in labor induction. Further randomized clinical trials are needed to investigate this further.

Polycystic ovarian syndrome (PCOS), which is a common endocrinopathy seen not only in adult women but also in female adolescents nowadays, is associated with reproductive, metabolic and cardiovascular problems.This article aims to review the current evidence on managing PCOS in adolescence. In addition, the pathophysiology, risk factors, clinical presentations and existing diagnostic criteria of PCOS will also be discussed.Certain risk factors are available to assist the clinicians to identify adolescents at risk of PCOS as the signs can be masked by the normal physiological changes during puberty. It is important to screen and diagnose adolescent PCOS in order to prevent the development of future infertility, type II diabetes mellitus, cardiovascular disease, and even endometrial cancer. Lifestyle modification is of the greatest benefit for adolescents in terms of management, with the condition that full support is available from both the clinicians and their families. The psychological impact of PCOS also constitutes a major concern in adolescent PCOS.

To evaluate the incidence, predisposing factors, early diagnosis and treatment options of heterotopic pregnancy (HP) following in vitro fertilization and embryo transfer (IVF-ET) procedure. A retrospective review study was performed to identify the HP cases after IVF-ET at the Reproductive Centre in Guangdong Women and Children’s Hospital in China between the years of 2002–2007. Twelve out of 1,476 pregnancies (0.81%) were diagnosed for HP, of which nine patients elected for exploratory salpingectomy, two patients received selective fetal reduction by embryo aspiration under ultrasound guidance, and one patient opted for expectant treatment. Postoperatively, four intrauterine pregnancies were continued to develop until term while two were delivered at 35 weeks of gestation. The achievement ratio of continuous pregnancy was 66.7% (6/9). The incidence of HP is increasing due to the widespread use of assisted reproductive technology. An early transvaginal sonography performed by experienced radiologist/radiographer is considered to be essential and beneficial in establishing early diagnosis of HP. Both salpingectomy and selective fetal reduction by embryo aspiration can be administered as one of the effective therapies for HP with the optimal outcome of intrauterine pregnancy.

- Abstract
People with metabolic syndrome (MetS) are at high risk of developing cardiovascular diseases such as coronary heart disease and other complications such as stroke, peripheral vascular disease and type II diabetes mellitus. MetS is also known as insulin resistance syndrome due to the fact that insulin action is reduced. The major risk factors for this syndrome are thought to be abdominal obesity and insulin resistance. Other factors which are associated with MetS are physical inactivity, ageing, hypertension, dyslipidaemia, and genetic predisposition. Family physicians have an important role in managing the chronic disease of MetS. The objective of this paper is to provide a narrative review of the current evidence on using complementary and alternative medicine to treat MetS. The recommendations and findings are also reviewed.
