Simultaneous prevention of unintended pregnancy and STIs: A challenging compromise
Background: Unintended pregnancy and sexually transmitted infections (STIs) are the major negative consequences of unsafe sex. Both are common and have long-term social and health consequences. Barrier methods of contraception can prevent both, but unfortunately they are much less effective than the more modern methods at pregnancy prevention. Modern effective contraceptives, however, do not protect against STIs and some may increase the risk of acquisition of infection. This comprehensive review discusses the magnitude of burden of reproductive ill-health, focussing on data from the European region, and explores the relationship between contraceptive use and STIs. methods: Searches were performed by using Medline, Popline, EMBASE, Cochrane Library and the Social Sciences Citation Index databases for relevant English language publications from 1995 to 2012. Summaries were discussed by the European Society of Human Reproduction and Embryology (ESHRE)Workshop Group. results: An understanding of patterns of sexual behaviour helps to understand the epidemiology of unintended pregnancy and STIs and gives pointers towards their prevention, but survey methodologies differ and results are hard to compare. Contraceptive prevalence and method mix vary widely between countries, and the use of the dual method of protection is very infrequent. Abortion rates have fallen in many European countries, particularly Eastern Europe, and contraceptive prevalence increased but unsafe abortion still accounts for 11% of maternal mortality in Eastern Europe. STIs are common but reporting systems are often rudimentary or non-existent and robust data are scarce. Providers still worry about the effect of intrauterine contraception on reproductive tract infections despite reassuring evidence to the contrary. New data on HIV acquisition and hormonal contraception are causing concern in settings where HIV infection is common. Newdevelopments in multipurpose technologies aimed at producing a single device/drug, which prevents infection and pregnancy simultaneously, are in early stages. While the benefits of national screening programmes for STIs remain uncertain, human papilloma virus (HPV) vaccination is clearly reducing HPV infection rates and gives hope for the public health benefits of other STI vaccines. conclusions: The consequences of unsafe sex-unintended pregnancy and STI-continue to present major public health problems worldwide even in countries where the prevalence of use of modern contraception is high. Robust systems for routine data collection are sorely needed in most countries and systematic attempts to compare patterns of sexual behaviour across men and women of all ages would be welcome
Modeling the potential benefit of an over-the-counter progestin-only pill in preventing unintended pregnancies in the U.S.
Emergency contraception from the pharmacy 20 years on:a mystery shopper study
Background Emergency contraception (EC) was approved in the UK as a pharmacy medicine for purchase without prescription in 1991. Twenty years later we conducted a study to characterise routine practice pharmacy provision of EC.
Study design Mystery shopper study of 30 pharmacies in Edinburgh, Dundee and London participating in a clinical trial of contraception after EC.
Methods Mystery shoppers, aged ≥16 years, followed a standard scenario requesting EC. After the pharmacy visit, they completed a proforma recording the duration of the consultation, where it took place, and whether advice was given to them about the importance of ongoing contraception after EC.
Results Fifty-five mystery shopper visits were conducted. The median reported duration of the consultation with the pharmacist was 6 (range 1–18) min. Consultations took place in a private room in 34 cases (62%) and at the shop counter in the remainder. In 27 cases (49%) women received advice about ongoing contraception. Eleven women (20%) left the pharmacy without EC due to lack of supplies or of a trained pharmacist. Most women were generally positive about the consultation.
Conclusions While availability of EC from UK pharmacies has undoubtedly improved access, the necessity to have a consultation, however helpful, with a pharmacist introduces delays and around one in five of our mystery shoppers left without getting EC. Consultations in private are not always possible and little advice is given about ongoing contraception. It is time to make EC available without a pharmacy consultation
Prevalence of infertility and help seeking among 15 000 women and men
STUDY QUESTION: What is the prevalence of infertility and of help seeking among women and men in Britain? SUMMARY ANSWER: One in eight women and one in ten men aged 16-74 years had experienced infertility, defined by unsuccessfully attempting pregnancy for a year or longer, and little more than half of these people sought medical or professional help. WHAT IS KNOWN ALREADY: Estimates of infertility and help seeking in Britain vary widely and are not easily comparable because of different definitions and study populations. STUDY DESIGN, SIZE, DURATION: A cross-sectional population survey was conducted between 2010 and 2012 with a sample of 15 162 women and men aged 16-74 years. PARTICIPANTS/MATERIALS, SETTING, METHODS: Participants completed the Natsal-3 questionnaire, using computer-assisted personal interviewing (CAPI) and computer-assisted self-interview (CASI). MAIN RESULTS AND THE ROLE OF CHANCE: The reported prevalence of infertility was 12.5% (CI 95% 11.7-13.3) among women and 10.1% (CI 95% 9.2-11.1) among men. Increased prevalence was associated with later cohabitation with a partner, higher socio-economic status and, for those who had a child, becoming parents at older ages. The reported prevalence of help seeking was 57.3% (CI 95% 53.6-61.0) among women and 53.2% (CI 95% 48.1-58.1) among men. Help seekers were more likely to be better educated and in higher status occupations and, among those who had a child, to have become parents later in life. LIMITATIONS, REASONS FOR CAUTION: These data are cross-sectional so it is not possible to establish temporality or infer causality. Self-reported data may be subject to recall bias. WIDER IMPLICATIONS OF THE FINDINGS: The study provides estimates of infertility and help seeking in Britain and the results indicate that the prevalence of infertility is higher among those delaying parenthood. Those with higher educational qualifications and occupational status are more likely to consult with medical professionals for fertility problems than others and these inequalities in help seeking should be considered by clinical practice and public health.

Use of effective contraception following provision of the progestogen-only pill for women presenting to community pharmacies for emergency contraception (Bridge-It): a pragmatic cluster-randomised crossover trial
BACKGROUND: Unless women start effective contraception after oral emergency contraception, they remain at risk of unintended pregnancy. Most women in the UK obtain emergency contraception from community pharmacies. We hypothesised that pharmacist provision of the progestogen-only pill as a bridging interim method of contraception with emergency contraception plus an invitation to a sexual and reproductive health clinic, in which all methods of contraception are available, would result in increased subsequent use of effective contraception. METHODS: We did a pragmatic cluster-randomised crossover trial in 29 UK pharmacies among women receiving levonorgestrel emergency contraception. Women aged 16 years or older, not already using hormonal contraception, not on medication that could interfere with the progestogen-only pill, and willing to give contact details for follow-up were invited to participate. In the intervention group, women received a 3-month supply of the progestogen-only pill (75 μg desogestrel) plus a rapid access card to a participating sexual and reproductive health clinic. In the control group, pharmacists advised women to attend their usual contraceptive provider. The order in which each pharmacy provided the intervention or control was randomly assigned using a computer software algorithm. The primary outcome was the use of effective contraception (hormonal or intrauterine) at 4 months. This study is registered, ISRCTN70616901 (complete). FINDINGS: Between Dec 19, 2017, and June 26, 2019, 636 women were recruited to the intervention group (316 [49·6%], mean age 22·7 years [SD 5·7]) or the control group (320 [50·3%], 22·6 years [5·1]). Three women (one in the intervention group and two in the control group) were excluded after randomisation. 4-month follow-up data were available for 406 (64%) participants, 25 were lost to follow-up, and two participants no longer wanted to participate in the study. The proportion of women using effective contraception was 20·1% greater (95% CI 5·2-35·0) in the intervention group (mean 58·4%, 48·6-68·2), than in the control group (mean 40·5%, 29·7-51·3 [adjusted for recruitment period, treatment group, and centre]; p=0·011).The difference remained significant after adjusting for age, current sexual relationship, and history of effective contraception use, and was robust to the effect of missing data (assuming missingness at random). No serious adverse events occurred. INTERPRETATION: Provision of a supply of the progestogen-only pill with emergency contraception from a community pharmacist, along with an invitation to a sexual and reproductive health clinic, results in a clinically meaningful increase in subsequent use of effective contraception. Widely implemented, this practice could prevent unintended pregnancies after use of emergency contraception.

Maternal Adiposity Influences Neonatal Brain Functional Connectivity
The neural mechanisms associated with obesity have been extensively studied, but the impact of maternal obesity on fetal and neonatal brain development remains poorly understood. In this study of full-term neonates, we aimed to detect potential neonatal functional connectivity alterations associated with maternal adiposity, quantified via body-mass-index (BMI) and body-fat-mass (BFM) percentage, based on seed-based and graph theoretical analysis using resting-state fMRI data. Our results revealed significant neonatal functional connectivity alterations in all four functional domains that are implicated in adult obesity: sensory cue processing, reward processing, cognitive control, and motor control. Moreover, some of the detected areas showing regional functional connectivity alterations also showed global degree and efficiency differences. These findings provide important clues to the potential neural basis for cognitive and mental health development in offspring of obese mothers and may lead to the derivation of imaging-based biomarkers for the early identification of risks for timely intervention
The influence of social factors on gender health
Male births exceed female births by 5-6% (for a sex ratio at birth of 1.05-1.06) while a women's life expectancy, on a global scale, is about 6 years longer. Thus within various age groups the male:female ratio changes over time. Until age 50 years men outnumber women; thereafter their numbers show a sharp decline. Consequently at age 80 years, there are many more women than men. An estimated 25% of this male excess mortality is due to biological causes, the rest being explained by behavioural, cultural and environmental factors. For both women and men, the main health risks related to lifestyle are smoking, alcohol, unhealthy diet and physical inactivity. In the year 2010, overweight (BMI: 25-29 kg/m2) and obesity (BMI: >30 kg/m2) were responsible for over 3 million deaths, with similar relative risks in men and women for overweight and obesity. Smoking and alcohol are the major causes of the global gender gap in mortality. For women in some parts of the world however pregnancy is also hazardous. On a global scale, in 2013 about 300 000 deaths were related to pregnancy, with sub-Saharan Africa registering the highest maternal mortality: over 500 maternal deaths per 100 000 births. Additional woman's health risks arise from gender discrimination, including sex-selective abortion, violence against women and early child marriage. Providers should be aware of the effect that these risks can have on both reproductive and general health. © 2016 The Author
The systematic guideline review: method, rationale, and test on chronic heart failure
Background: Evidence-based guidelines have the potential to improve healthcare. However, their de-novo-development requires substantial resources-especially for complex conditions, and adaptation may be biased by contextually influenced recommendations in source guidelines. In this paper we describe a new approach to guideline development-the systematic guideline review method (SGR), and its application in the development of an evidence-based guideline for family physicians on chronic heart failure (CHF).
Methods: A systematic search for guidelines was carried out. Evidence-based guidelines on CHF management in adults in ambulatory care published in English or German between the years 2000 and 2004 were included. Guidelines on acute or right heart failure were excluded. Eligibility was assessed by two reviewers, methodological quality of selected guidelines was appraised using the AGREE instrument, and a framework of relevant clinical questions for diagnostics and treatment was derived. Data were extracted into evidence tables, systematically compared by means of a consistency analysis and synthesized in a preliminary draft. Most relevant primary sources were re-assessed to verify the cited evidence. Evidence and recommendations were summarized in a draft guideline.
Results: Of 16 included guidelines five were of good quality. A total of 35 recommendations were systematically compared: 25/35 were consistent, 9/35 inconsistent, and 1/35 un-rateable (derived from a single guideline). Of the 25 consistencies, 14 were based on consensus, seven on evidence and four differed in grading. Major inconsistencies were found in 3/9 of the inconsistent recommendations. We re-evaluated the evidence for 17 recommendations (evidence-based, differing evidence levels and minor inconsistencies) - the majority was congruent. Incongruity was found where the stated evidence could not be verified in the cited primary sources, or where the evaluation in the source guidelines focused on treatment benefits and underestimated the risks. The draft guideline was completed in 8.5 man-months. The main limitation to this study was the lack of a second reviewer.
Conclusion: The systematic guideline review including framework development, consistency analysis and validation is an effective, valid, and resource saving-approach to the development of evidence-based guidelines
A randomized, placebo-controlled trial of prednisone in early Henoch Schönlein Purpura [ISRCTN85109383]
BACKGROUND: Henoch Schönlein Purpura (HSP) is the most common systemic vasculitis of childhood. There is considerable controversy over whether children with HSP should be treated with corticosteroids. The goal of this study was to investigate whether early corticosteroid administration could reduce the rate of renal or gastrointestinal complications in children with HSP. METHODS: Forty children with HSP, seen in the emergency room of a tertiary-care, paediatric centre, entered a randomized, double-blind, placebo controlled study. The treatment group (n = 21) received oral prednisone, 2 mg/kg/day for one week, with weaning over a second week, while the placebo group (n = 19) received an identical appearing placebo. Co-primary outcomes were the rate of renal involvement at one year and the rate of acute gastrointestinal complications. Co-primary outcomes were analysed using Fisher's Exact test. RESULTS: At one year, there was no difference in the rate of renal involvement (3/21 prednisone group vs. 2/19 placebo group, P = 1.0). There was also no statistically significant difference in the rate of acute gastrointestinal complications (2/21 prednisone group vs. 3/19 placebo group, P = 0.7). Two children in the placebo group did experience intussusceptions compared with none in the prednisone group (P = 0.2). CONCLUSIONS: Early prednisone therapy in HSP does not appear to reduce the risk of renal involvement at one year, or the risk of acute gastrointestinal complications. There may be a reduced risk of intussusception. The routine, early use of prednisone in uncomplicated HSP cannot be recommended at this time
