Research priority setting in women's health: a systematic review.

BACKGROUND: Developing a shared agenda is an important step in ensuring future research has the necessary relevance. OBJECTIVE: To characterise research priority setting partnerships (PSPs) relevant to women's health. SEARCH STRATEGY: Included studies were identified by searching MEDLINE and the James Lind Alliance (JLA) database. SELECTION CRITERIA: Priority setting partnerships using formal consensus methods. DATA COLLECTION AND ANALYSIS: Descriptive narrative to describe the study characteristics, methods, and results. MAIN RESULTS: Ten national and two international PSPs were identified. All PSPs used the JLA method to identify research priorities. Nine PSPs had published a protocol. Potential research uncertainties were gathered from guidelines (two studies), Cochrane reviews (five studies), and surveys (12 studies). The number of healthcare professionals (31-287), patients (44-932), and others (33-139) who responded to the survey, and the number of uncertainties submitted (52-4767) varied. All PSPs entered confirmed research uncertainties (39-104) into interim priority setting surveys and healthcare professionals (31-287), patients (44-932), and others (33-139) responded. All PSPs entered a short list of research uncertainties into a consensus development meeting, which enabled healthcare professionals (six to 21), patients (eight to 14), and others (two to 13) to identify research priorities (ten to 15). Four PSPs have published their results. CONCLUSION: Future research priority setting studies should publish a protocol, use formal consensus development methods, and ensure their methods and results are comprehensively reported. TWEETABLE ABSTRACT: Research published in @BJOGtweets highlights future research priorities across women's health, including @FertilityTop10, @jamesmnduffy.

Pupil-led sex education in England (RIPPLE study): cluster-randomised intervention trial.

BACKGROUND: Improvement of sex education in schools is a key part of the UK government's strategy to reduce teenage pregnancy in England. We examined the effectiveness of one form of peer-led sex education in a school-based randomised trial of over 8000 pupils. METHODS: 29 schools were randomised to either peer-led sex education (intervention) or to continue their usual teacher-led sex education (control). In intervention schools, peer educators aged 16-17 years delivered three sessions of sex education to 13-14 year-old pupils from the same schools. Primary outcome was unprotected (without condom) first heterosexual intercourse by age 16 years. Analysis was by intention to treat. FINDINGS: By age 16 years, significantly fewer girls reported intercourse in the peer-led arm than in the control arm, but proportions were similar for boys. The proportions of pupils reporting unprotected first sex did not differ for girls (8.4% intervention vs 8.3% control) or for boys (6.2% vs 4.7%). Stratified estimates of the difference between arms were -0.4% (95% CI -3.7% to 2.8%, p=0.79) for girls and -1.4% (-4.4% to 1.6%, p=0.36) for boys. At follow-up (mean age 16.0 years [SD 0.32]), girls in the intervention arm reported fewer unintended pregnancies, although the difference was borderline (2.3% vs 3.3%, p=0.07). Girls and boys were more satisfied with peer-led than teacher-led sex education, but 57% of girls and 32% of boys wanted sex education in single-sex groups. INTERPRETATION: Peer-led sex education was effective in some ways, but broader strategies are needed to improve young people's sexual health. The role of single-sex sessions should be investigated further.

Dawn phenomenon and Somogyi effect in IDDM.

We examined the clinical relevance of a rise in fasting blood glucose (BG) between 0300 and 0600 in 97 patients with insulin-dependent diabetes mellitus (IDDM) receiving sequentially conventional (CT) and basal-bolus (BBIT) insulin therapies and assessed the impact of one potential causal factor, i.e., posthypoglycemic hyperglycemia, with 231 BG profiles (97 during CT, 134 during BBIT) in which BG was measured every 3 h over a 24-h period. A rise in BG between 0300 and 0600 occurred in 157 of 231 (68%) profiles. The mean magnitude of this rise was 56 +/- 39 mg/dl and was lower (P less than .05) during BBIT (48 +/- 35 mg/dl, n = 97) than CT (62 +/- 43 mg/dl, n = 97). A dawn rise (between 0300 and 0600) greater than 50 mg/dl occurred in 40 of 97 (41%) profiles during CT and 26 of 97 (27%) during BBIT (P less than .05). When all profiles were grouped according to the magnitude of this rise in BG, the mean daytime BG (from 0900 to 1800) was higher (P less than .05) after an 0300-0600 BG rise greater than 50 mg/dl compared with groups of profiles showing either a fall in BG or a rise less than 50 mg/dl; a rise in BG between 0300 and 0600 correlated (r = .38, P less than .0001) with the subsequent mean daytime BG. Nocturnal hypoglycemia (BG less than 60 mg/dl) recorded at 2400 and/or 0300 occurred in 57 of 231 (25%) profiles.(ABSTRACT TRUNCATED AT 250 WORDS)

The relationship between socioeconomic status and diabetes control and complications in the EURODIAB IDDM Complications Study.

OBJECTIVE: To determine whether there are socioeconomic differences in diabetes control and complications in people with IDDM. RESEARCH DESIGN AND METHODS: We conducted a prevalence survey of 1,217 men and 1,170 women with IDDM age 25-60 years from European clinics. Age at completion of education defined socioeconomic status: < or = 14 years defined those with primary education; 15-18 years, as secondary education; and > 19 years, as college education. Glycemic control, lipids, diet, retinopathy, neuropathy, and heart disease were assessed centrally. RESULTS: People with a primary education were older and had diabetes for longer than those with a college education. The mean percentage of HbA1c was worst in the primary-educated men (6.6 vs. 6.1%, P = 0.0007 for trend) and women (6.5 vs. 6.0%, P = 0.0007). Total cholesterol level was higher in primary-educated than in college-educated men (5.6 vs 5.3 mmol/l, P = 0.002), as was triglyceride level (1.23 vs. 1.02 mmol/l, P = 0.0001). College-educated people were the least likely to be current smokers (P < 0.0001), and were most likely to partake in vigorous exercise (P < 0.001). Surprisingly, There was little difference in the prevalence of heart disease by educational status in men, while it was highest in the least educated women, but proliferative retinopathy was more common in primary- than in college-educated men (16 vs 10%, P = 0.04) as was macroalbuminuria (15 vs 9%, P = 0.03). Glycemic control could not fully account for these differences. CONCLUSIONS: Healthy lifestyles are more prevalent in better educated men and women with IDDM, but these are not reflected in heart disease prevalence in men. The lower prevalence of severe microvascular complications in better educated men, unaccounted for by better glycemic control, requires further investigation.

The relationship between smoking and microvascular complications in the EURODIAB IDDM Complications Study.

OBJECTIVE: To examine the relationship between smoking and both glycemic control and microvascular complications in patients with insulin-dependent diabetes mellitus (IDDM). RESEARCH DESIGN AND METHODS: This was a prevalence survey of 3,250 men and women aged 15-60 years with IDDM from 31 diabetes centers in 16 European countries. Participants completed a questionnaire, had retinal photographs taken, and performed a 24-h urine collection. HbA1c, frequency of hypoglycemic and ketoacidotic episodes, urinary albumin excretion rates, and retinopathy were compared by smoking category. RESULTS: The prevalence of smoking was 35% in men and 29% in women. Current smokers had poorer glycemic control and, among men, were more likely to have had a ketoacidotic episode than were those who never smoked. Ex-smokers had equivalent glycemic control and marginally more hypoglycemic episodes did than those who never smoked. Current smokers had a higher prevalence of microalbuminuria and total retinopathy than did those who never smoked. Ex-smokers had a higher prevalence of macroalbuminuria and proliferative retinopathy than did those who never smoked, but both had a similar prevalence of microalbuminuria. Adjustment for either current or long-term glycemic control could not fully account for these differences. CONCLUSIONS: Smoking is associated with poorer glycemic control and an increased prevalence of microvascular complications compared with not smoking. Ex-smokers can achieve glycemic control equivalent to and have a prevalence of early complications similar to that of those who never smoked. We suggest that poorer glycemic control can account for some of the increased risk of complications in smokers, and that quitting smoking would be effective in reducing the incidence of complications. Urgent action is required to reduce the high smoking rates in people with IDDM.

The effect of HIV diagnosis on reproductive experience. Study Group for the Medical Research Council Collaborative Study of Women with HIV.

OBJECTIVES: To compare rates of reproductive events before and after HIV diagnosis in a cohort of women with HIV infection, and to consider the impact of HIV diagnosis on the outcome of pregnancy. DESIGN: Observational cohort study of 503 women recruited from 15 genitourinary medicine/HIV clinics in Britain and Ireland. The 503 women had 580 pregnancies before diagnosis of HIV infection and 202 after HIV diagnosis. METHODS: Using date of birth, date of HIV diagnosis, the outcome of all lifetime pregnancies and date of each outcome, age-specific rates (per 100 women-years) of pregnancy, miscarriage, termination and live-birth were calculated before HIV diagnosis, and separately after HIV diagnosis. Rates after HIV diagnosis were age-standardized for comparison with rates before HIV diagnosis. Rates were also calculated separately by ethnic group and HIV transmission group. RESULTS: In women aged 20-34 years, the age-adjusted live-birth rate fell by 44% from 10.2 [95% confidence interval (CI), 9.2-11.2] per 100 women-years before HIV diagnosis to 5.7 (95% CI, 4.3-7.1) after diagnosis. Most of the decline reflected an increase in termination rate from 3.5 (95% CI, 2.9-4.1) before HIV diagnosis to 6.3 (95% CI, 4.7-7.9) after diagnosis. A decline in live-births together with a rise in termination after HIV diagnosis was a consistent finding across age and ethnic groups. However, black African women had the smallest reduction in live-births, despite the greatest increase in termination, because the pregnancy rate increased after HIV diagnosis in this group. CONCLUSIONS: Diagnosis of HIV infection in women has a substantial impact in reducing live-birth rates. These findings have important implications for expanding HIV testing in women. They highlight the need for better understanding of reproductive decision-making in the context of HIV infection and better contraceptive support for HIV-infected women and their partners.

Spectrum of disease in Africans with AIDS in London.

OBJECTIVE: To compare the spectrum of disease, severity of immune deficiency and chemoprophylaxis prescribed in HIV-infected African and non-African patients in London. DESIGN: Retrospective review of case notes of all HIV-infected Africans and a comparison group of non-Africans attending 11 specialist HIV/AIDS Units in London. MAIN OUTCOME MEASURES: Comparison of demographic information, first and subsequent AIDS-defining conditions, levels of immune deficiency, and chemoprophylactic practices between the African and non-African groups. RESULTS: A total of 1056 Africans (313 developing AIDS) and 992 non-Africans (314 developing AIDS) were studied. Africans presented later than non-Africans (median CD4+ lymphocyte counts at diagnosis 238 and 371 x 10(6)/l, respectively). Tuberculosis accounted for 27% of initial episodes of AIDS in Africans and 5% in non-Africans; Pneumocystis carinii pneumonia (PCP) was the initial AIDS-defining condition in 34% of non-Africans and 17% of Africans. The incidence of tuberculosis in Africans with another AIDS-indicator disease was 16 per 100 person-years. PCP prophylaxis was prescribed for 40% Africans and 32% non-Africans; only 8% of Africans received tuberculosis preventive therapy. CONCLUSIONS: HIV-infected African patients presented at lower levels of CD4+ lymphocyte count, at a more advanced clinical stage, and with different AIDS-indicator diseases as compared with non-Africans. Prophylaxis against tuberculosis should be considered for all HIV-infected African patients in industrialized countries. The high incidence of diseases that are indicative of advanced immunodeficiency (e.g., cytomegalovirus disease) in African patients contrasts with data from Africa, suggesting better survival chances in the UK.

Ethnic differences in women with HIV infection in Britain and Ireland. The study group for the mrc collaborative study of HIV infection in women.

OBJECTIVE: To examine ethnic differences in the socio-epidemiological and clinical characteristics of a cohort of women with HIV infection in Britain and Ireland. DESIGN AND METHODS: Analysis of baseline data (ethnic group, sexual history, likely route of HIV infection, reasons for HIV testing and first AIDS-defining disease) from 400 women with HIV infection recruited into a cohort study from 15 genitourinary medicine/HIV clinics in Britain and Ireland. RESULTS: Sixty-five per cent of women were white and 29% black African. Their median number of lifetime sexual partners was seven and three, respectively (P < 0.001). Ninety-three per cent of black African and 43% of white women were probably infected through sexual intercourse. Injecting drug use was the most likely route of infection in 55% of white women, but none of the black African women. Perceived risk (33%) or investigation of symptoms (26%) were the most common reasons for HIV testing. Seven per cent of white women and 16% of black African women (P < 0.001) had AIDS when HIV infection was diagnosed. The distribution of first AIDS-defining diagnoses differed (P = 0.001) by ethnic group. For white women, the most common disease was Pneumocystis carinii pneumonia; for black African women it was pulmonary tuberculosis. CONCLUSION: There are important differences between black African and white women in sexual history and route of transmission, disease stage at diagnosis and pattern of AIDS-defining diseases.

Effects of sex and age on growth hormone response to growth hormone-releasing hormone in healthy individuals.

The influence of age and sex on human GH secretion is controversial. In previous studies, serum GH responses to arginine and insulin-induced hypoglycemia were significantly higher in pre- and postovulatory women than in men. In contrast, recent studies suggest that GH responsiveness to GHRH is higher in normal young men than in age-matched women. To clarify the question of sex and age influence on GHRH-(1-44)-stimulated GH secretion, we studied 116 normal women and men (with body mass indexes of 18-25 and 19-26, respectively) between the ages of 18 and 95 yr. The peak serum GH increments after GHRH administration were significantly higher in premenopausal women than in age-matched men (P less than 0.003 for the age group 18-30 yr and P less than 0.03 for the age group 30-50 yr, as assessed by analysis of variance). The responses were not different in postmenopausal women and age-matched men. Multiple regression analysis revealed a significant negative correlation between GHRH-induced GH responses (integrated area under the curve) and age in both women (P less than 0.002) and men (P less than 0.001). In addition, we determined basal serum testosterone, estradiol, cortisol, and PRL levels in all subjects. Multivariate regression analysis of the GH responses to GHRH administration revealed a significant positive correlation (P less than 0.01) between serum estradiol and both GH increase and the area under the GH response curve. No correlation was found between GHRH-stimulated GH secretion and basal serum cortisol, testosterone, or PRL concentrations. Our data clearly demonstrate a marked influence of both sex and age on GHRH-stimulated GH secretion. We found a higher GH increase in premenopausal women compared with age matched-men and an age-dependent decrease in GHRH-stimulated GH secretion in both sexes. Furthermore, in women a significant influence of estradiol on GH secretion after GHRH administration could be demonstrated.

Regulation of vasopressin receptors in deoxycorticosterone acetate-salt hypertension.

Since arginine vasopressin may play a role in mineralocorticoid hypertension, we examined the effects of deoxycorticosterone acetate (DOCA)-salt on vasopressin V1 and V2 receptor binding and their second messengers, inositol phosphate and adenylate cyclase, respectively, in liver and kidney to determine whether altered vasopressin receptor binding is pathogenetic in mineralocorticoid hypertension. The mean arterial blood pressure of mineralocorticoid (DOCA-salt)-treated rats (163 +/- 1 mm Hg) was increased compared with control salt-treated rats (salt) (122 +/- 1 mm Hg) and water-treated rats (120 +/- 1 mm Hg; p less than 0.001). Mineralocorticoid treatment also increased plasma sodium, osmolality, and vasopressin concentration (p less than 0.001). In the hypertensive animals, there was a reduction in hepatic V1 (DOCA-salt, 91 +/- 12; salt, 132 +/- 13; and water, 145 +/- 13 fmol/mg protein; p less than 0.05) and renal V2 receptor binding density (DOCA-salt, 53 +/- 5; salt, 93 +/- 9; and water, 95 +/- 9 fmol/mg protein; p less than 0.01), although receptor affinities remained unaltered. In contrast, the density of renal V1 receptors was increased by mineralocorticoid treatment (DOCA-salt, 24 +/- 2; salt, 16 +/- 2; water, 18 +/- 1 fmol/mg protein; p less than 0.05), although the affinity was unchanged. Downregulation of V2 receptors was associated with a decrease in maximum cyclic adenosine monophosphate levels (DOCA-salt, 19 +/- 4; salt, 49 +/- 6; water, 53 +/- 9 pmol.mg protein-1.10 min-1; p less than 0.05), whereas changes in V1 receptor levels were not associated with changes in maximum inositol phosphate levels.(ABSTRACT TRUNCATED AT 250 WORDS)

Blood pressure-lowering effect of an orally active vasopressin V1 receptor antagonist in mineralocorticoid hypertension in the rat.

We studied the contribution of vasopressin to the maintenance of high blood pressure in deoxycorticosterone acetate (DOCA)-salt hypertension in the rat using the nonpeptide orally effective vasopressin V1 receptor antagonist OPC-21268. Binding kinetic studies demonstrated that oral OPC-21268 (30 mg/kg) acted as a competitive antagonist at the vasopressin V1 receptor in DOCA-salt and salt control rats. Basal mean intra-arterial blood pressure was 140 +/- 4 mm Hg (n = 12) in DOCA-salt rats compared with 111 +/- 2 mm Hg in salt control rats (n = 18). Acute oral OPC-21268 (30 mg/kg) significantly (P < .01) reduced mean intra-arterial pressure in DOCA-salt hypertension, with an average maximal decrease of 24 +/- 3 mm Hg occurring at 2.5 +/- 0.7 hours after dosing. Systolic blood pressure (tail-cuff) in DOCA-salt rats was 178 +/- 2 mm Hg. Chronic oral OPC-21268 (30 mg/kg) twice daily for 7 days significantly (P < .01) reduced systolic blood pressure in DOCA-salt hypertension, with an average maximal decrease of 27 +/- 5 mm Hg. The antihypertensive effect was reversed 5 days after treatment with OPC-21268 was stopped. In water control rats basal systolic pressure (120 +/- 1 mm Hg, n = 20) was unchanged by chronic oral OPC-21268 (30 mg/kg twice daily for 7 days), and this was confirmed by direct measurement of mean intra-arterial pressure. After chronic oral OPC-21268 (30 mg/kg twice daily for 7 days) hepatic V1 receptor binding was significantly reduced for up to 10 hours (P < .05).(ABSTRACT TRUNCATED AT 250 WORDS)

[3H]desGly-NH2(9)-d(CH2)5[D-Ileu2,Ileu4]AVP: an AVP V2 receptor antagonist radioligand.

Binding characteristics of the selective V2 antagonist radioligand [3H]desGly-NH2(9)-d(CH2)5[D-Ileu2,Ileu4]AVP to rat kidney were determined. Binding was specific, saturable and reversible. The peptide bound to a single class of high-affinity binding sites with Bmax 69.4 +/- 6.8 fmol/mg protein and KD 2.8 +/- 0.3 nM. AVP and other related peptides displaced [3H]desGly-NH2(9)-d(CH2)5[D-Ileu2,Ileu4]AVP binding. The order of potency of inhibition was desamino-D-AVP greater than AVP greater than d(CH2)5[D-Ileu2,Ileu4]AVP greater than oxytocin greater than d(CH2)5[Tyr(Me)2]AVP greater than d(CH2)5[sarcosine7]AVP, which is typical of a selective V2 radioligand. Autoradiographic localization of [3H]desGly-NH2(9)-d(CH2)5[D-Ileu2,Ileu4]AVP binding sites in kidney showed dense binding in the inner and outer medulla with less binding in the cortex, which is consistent with known renal V2 receptor distribution.

Effect of social exclusion on the risk of teenage pregnancy: development of hypotheses using baseline data from a randomised trial of sex education.

STUDY OBJECTIVE: The UK government argues that "social exclusion" increases risk of teenage pregnancy and that educational factors may be dimensions of such exclusion. The evidence cited by the government is limited to reporting that socioeconomic disadvantage and educational attainment influence risk. Evidence regarding young people's attitude to school is not cited, and there is a lack of research concerning the UK. This paper develops hypotheses on the relation between socioeconomic and educational dimensions of social exclusion, and risk of teenage pregnancy, by examining whether dislike of school and socioeconomic disadvantage are associated with cognitive/behavioural risk measures among 13/14 year olds in English schools. DESIGN: Analysis of data from the baseline survey of a study of sex education. SETTING AND PARTICIPANTS: 13/14 year old school students from south east England. MAIN RESULTS: The results indicate that socioeconomic disadvantage and dislike of school are associated with various risk factors, each with a different pattern. Those disliking school, despite having comparable knowledge to those liking school, were more likely to have sexual intercourse, expect sexual intercourse by age 16, and expect to be parents by the age of 20. For most associations, the crude odds ratios (ORs) and the ORs adjusted for the other exposure were similar, suggesting that inter-confounding between exposures was limited. CONCLUSIONS: It is hypothesised that in determining risk of teenage pregnancy, the two exposures are independent. Those disliking school might be at greater risk of teenage pregnancy because they are more likely to see teenage pregnancy as inevitable or positive.

Microalbuminuria is not rare before 5 years of IDDM. EURODIAB IDDM Complications Study Group and the WHO Multinational Study of Vascular Disease in Diabetes Study Group.

Microalbuminuria is thought to be rare in people with insulin-dependent diabetes mellitus (IDDM) for less than 5 years. We measured its prevalence in 733 clinic-attending IDDM patients with diabetes duration of 1-5 years in two large multicenter studies [EURODIAB IDDM Complications Study and the World Health Organization (WHO) Multinational Study]. We also compared characteristics of microalbuminuric patients with IDDM for 1-5 years versus more than 5 years' duration. Albumin excretion rate was measured from a timed 24-h urine collection in the EURODIAB Study. Proteinuria was measured by the salicylsulphonic acid test in the WHO Study. The prevalence of microalbuminuria (20-200 micrograms/min, EURODIAB) was 18% [95% confidence interval (CI) 13%-22%)]. The prevalence of light proteinuria was 15% (9%-20%, WHO study). Raised protein excretion was a consistent finding in 34 of the 36 centers. The increased cardiovascular risk (raised blood pressure and total cholesterol) associated with microalbuminuria in patients with IDDM for more than 5 years was also apparent in those with diabetes for 1-5 years. However, repeat urine testing suggested that microalbuminuria before 5 years was more likely to be transient or reversible. In conclusion, these two studies in 36 centers, which used different methods more than 10 years apart, show consistently that raised urinary albumin excretion occurs before 5 years of IDDM. The clinical significance of this needs to be examined by prospective observation.

Evaluation of self-taken samples for the presence of genital Chlamydia trachomatis infection in women using the ligase chain reaction assay.

The aim of this study was to evaluate the sensitivity and acceptability of self-taken vulval-introital (VI) samples, first-catch urine (FCU) samples and clinician-obtained cervical samples for the presence of genital Chlamydia trachomatis infections in women using the ligase chain reaction (LCR) assay. One hundred and four patients were enrolled, of whom 54 patients had chlamydial DNA in at least one of the samples tested. The sensitivity of the cervical sample was 96.3%, vulval-introital sample in LCR buffer 92.6%, vulval-introital swab collected dry 88.9%, FCU stored at +2-8 degrees C 81.5%, FCU stored at room temperature 77.8% and FCU stored with 2% w/v boric acid at room temperature 87.0%. Self-taken vulval-introital LCR samples were shown to be an acceptable alternative to a clinician-obtained LCR sample. The addition of boric acid may overcome the need for a continuous cold chain for FCU samples.

Risk of cancer in patients with HIV disease. London African HIV/AIDS Study Group.

The aim of this study was to compare cancer incidence in a cohort of HIV-infected patients with the incidence rates in the population of South East England. Data collected for a retrospective cohort study of 2048 HIV-infected patients were analysed to examine the incidence of cancer. Cases of cancer occurring in South East England from 1985-1995 were obtained from the Thames Cancer Registry. Standardized incidence ratios were calculated by comparison of the observed number of cases for each cancer type in HIV-infected non-Africans with the numbers expected, calculated from the age and sex specific registration rates for the South East England population using person-years of observation. The crude incidence rates of cancer were calculated for HIV-infected Africans. The incidence of non-AIDS defining cancers such as Hodgkin's disease (standardized incidence ratio 22; 95% CI: 3-80) and anal cancer (standardized incidence ratio 125; 95% CI: 3-697) were significantly increased for non-African males with HIV disease. Anal cancer was also significantly increased for non-African females (standardized incidence ratio 1667; 95% CI: 43-9287). Kaposi's sarcoma (KS) was the commonest cancer among HIV-infected Africans and males had an incidence which was nearly 3 times that of females. There is evidence to suggest that the risks for other non-AIDS defining cancers were significantly increased in persons with HIV disease which may have implications for HIV/AIDS surveillance.

Complications and cardiovascular risk factors in insulin-dependent diabetes--findings in an Irish clinic and in other European centres.

The Eurodiab Insulin Dependent Diabetes (IDDM) Complications Study was a cross-sectional investigation of a stratified random sample of IDDM patients attending 31 clinics in 16 European countries. We compared the findings in the only participating Irish centre (Cork Regional Hospital) with those of the study group as a whole. There were fewer episodes of ketosis but severe hypoglycaemia occurred more frequently in Cork patients, when compared to the full study group. There were no significant differences in the prevalence of background retinopathy, proliferative retinopathy, microalbuminuria, macroalbuminuria or peripheral neuropathy, when the two groups were compared. However, autonomic neuropathy was significantly less common in Cork. The prevalence of cardiovascular disease was slightly lower than the Eurodiab average in Cork patients, and cardiovascular risk factors were more favourable. Waist-hip ratio and total plasma cholesterol were significantly lower than in the full study group. The prevalence of hypertension was similar, but there were fewer smokers in Cork than in most other centres.

A cognitive behavioural intervention to reduce sexually transmitted infections among gay men: randomised trial.

OBJECTIVE: To determine the effectiveness of a brief cognitive behavioural intervention in reducing the incidence of sexually transmitted infections among gay men. DESIGN: Randomised controlled trial with 12 months' follow up. SETTING: Sexual health clinic in London. PARTICIPANTS: 343 gay men with an acute sexually transmitted infection or who reported having had unprotected anal intercourse in the past year. MAIN OUTCOME MEASURES: Number of new sexually transmitted infections diagnosed during follow up and self reported incidence of unprotected anal intercourse. RESULTS: 72% (361/499) of men invited to enter the study did so. 90% (308/343) of participants returned at least one follow up questionnaire or re-attended the clinic and requested a check up for sexually transmitted infections during follow up. At baseline, 37% (63/172) of the intervention group and 30% (50/166) of the control group reported having had unprotected anal intercourse in the past month. At 12 months, the proportions were 27% (31/114) and 32% ( 39/124) respectively (P=0.56). However, 31% (38/123) of the intervention group and 21% (35/168) of controls had had at least one new infection diagnosed at the clinic (adjusted odds ratio 1.66, 95% confidence interval 1.00 to 2.74). Considering only men who requested a check up for sexually transmitted infections, the proportion diagnosed with a new infection was 58% (53/91) for men in the intervention group and 43% (35/81) for men in the control group (adjusted odds ratio 1.84, 0.99 to 3.40). Using a regional database that includes information from 23 sexual health clinics in London, we determined that few participants had attended other sexual health clinics. CONCLUSIONS: This behavioural intervention was acceptable and feasible to deliver, but it did not reduce the risk of acquiring a new sexually transmitted infection among these gay men at high risk. Even carefully designed interventions should not be assumed to bring benefit. It is important to evaluate their effects in randomised trials with objective clinical end points.

A cross-sectional study of Mycoplasma genitalium infection and correlates in women undergoing population-based screening or clinic-based testing for Chlamydia infection in London.

OBJECTIVE: To determine Mycoplasma genitalium infection and correlates among young women undergoing population-based screening or clinic-based testing for Chlamydia infection. DESIGN: Cross-sectional study. SETTING: National Chlamydia Screening Programme (NCSP) and two London sexually transmitted infection (STI) clinics. PARTICIPANTS: 2441 women aged 15-64 years who participated in the NCSP and 2172 women who attended two London STI clinics over a 4-month period in 2009. OUTCOME MEASURES: (1) M genitalium prevalence in defined populations (%). (2) Age-adjusted ORs (aORs) for correlates of M genitalium infection. RESULTS: The overall frequency of M genitalium and Chlamydia trachomatis was 3% and 5.4%, respectively. Co-infection was relatively uncommon (0.5% of all women); however 9% of women with C trachomatis also had M genitalium infection. M genitalium was more frequently detected in swab than urine samples (3.9 vs 1.3%, p<0.001) with a significantly higher mean bacterial load (p ≤ 0.001). Among NCSP participants, M genitalium was significantly more likely to be diagnosed in women of black/black British ethnicity (aOR 2.3, 95% CI 1.2 to 4.5, p=0.01). M genitalium and C trachomatis and were both significantly associated with multiple sexual partners in the past year (aOR 2.4, 95% CI 1.3 to 4.4, p=0.01 and aOR 2.0, 95% CI 1.4 to 2.8, p<0.01). Among STI clinic attendees, M genitalium was more common in women who were less than 25 years in age. CONCLUSIONS: M genitalium is a relatively common infection among young women in London. It is significantly more likely to be detected in vulvovaginal swabs than in urine samples. Co-infection with Chlamydia is uncommon. The clinical effectiveness of testing and treatment strategies for M genitalium needs further investigation.
