Associations of fibrinogen and C-reactive protein with prevalent and incident coronary heart disease are attenuated by adjustment for confounding factors. British Women's Heart and Health Study

A cross sectional and prospective analysis of 3,745 British women aged 60-79 years at baseline was undertaken. Among these women there were 570 prevalent cases of coronary heart disease (CHD) and 151 new cases among 12,641 person-years of follow up of women who were free of CHD at baseline. Both fibrinogen and CRP were associated with indicators of socioeconomic position in childhood and adulthood and there was a cumulative effect of socioeconomic position from across the life course. The age-adjusted odds ratio (95% confidence interval) of prevalent CHD for a 1 unit (1 g/L) increase in fibrinogen was 1.29 (1.12, 1.49); with full adjustment for all potential confounding factors this attenuated to 1.09 (0.93, 1.28). The hazards ratio for incident CHD among those free of disease at baseline was 1.28 (1.00, 1.64); with full adjustment for all potential confounding factors this attenuated to 1.09 (0.84, 1.44). Similar effects of adjustment for confounding factors were seen for the associations between CRP and both prevalent and incident CHD. By contrast, the strong positive association between smoking (an established causal risk factor for CHD) and CHD was not attenuated by adjustment for life course socioeconomic position or other risk factors. We conclude that fibrinogen and CRP predict CHD but may not be causally related to it.     

A prospective, randomized study comparing laparoscopic ovarian cystectomy versus fenestration and coagulation in patients with endometriomas

OBJECTIVE: To determine the difference between two laparoscopic methods for the management of endometriomas with regard to recurrence of signs and symptoms and pregnancy rate. DESIGN: Prospective, randomized clinical trial. SETTING: Infertility and gynecologic endoscopy units of two medical university hospitals. PATIENT(S): One hundred patients with endometriomas who had either infertility or pelvic pain. INTERVENTION(S): Patients were randomly divided into two groups; one group underwent cystectomy (group 1), and fenestration and coagulation were performed for the other (group 2). MAIN OUTCOME MEASURE(S): A comparison of recurrence of signs and symptoms of endometriomas and pregnancy rates in two groups. RESULT(S): Fifty-two patients were studied in group 1 and 48 in group 2. The recurrence of symptoms, such as pelvic pain and dysmenorrhea, was 15.8% in group 1 and 56.7% in group 2 after 2 years. The rate of reoperation was 5.8% in group 1 and 22.9% in group 2 and these differences were statistically significant. The cumulative pregnancy rate was significantly higher in group 1 (59.4%) than in group 2 (23.3%) at 1-year follow-up. CONCLUSION(S): Laparoscopic cystectomy of endometriomas is a better choice than fenestration and coagulation because the former technique leads to a lower recurrence of signs and symptoms and a lower rate of reoperation and a higher cumulative pregnancy rate than the latter.     

Women's knowledge about treatment to prevent mother-to-child human immunodeficiency virus transmission

OBJECTIVE: To provide national estimates of knowledge about treatments available to reduce mother-to-infant human immunodeficiency virus (HIV) transmission among U.S. women of childbearing age. METHODS: We used data from 55712 women aged 18 to 44 years who responded to questions on antiretroviral treatment in the 2001 Behavioral Risk Factor Surveillance System. We obtained the percentage of women who correctly answered a question on treatment to prevent mother-to-child transmission of HIV and determined factors independently associated with such knowledge using a multiple logistic regression model. RESULTS: Overall, the percentage of women who correctly stated that treatment existed to help prevent mother-to-child transmission of HIV was 58.6% (95% confidence interval 57.9, 59.3). In the multiple logistic regression model that controlled for sociodemographics, having correct knowledge about treatment to prevent mother-to-child HIV transmission was independently associated with being black, younger age (18-34 years), college level education, and having been tested for HIV. Current pregnancy was not an independent predictor of having knowledge about the availability of treatment to prevent mother-to-child transmission. CONCLUSION: Among US women of childbearing age, just over one half had correct knowledge of effective perinatal HIV prevention strategies. Increasing the awareness of these treatments may lead to greater uptake of HIV testing among pregnant women.     

A prospective,double-blind,randomized, placebo-controlled clinical trial of bromocriptin in clomiphene-resistant patients with polycystic ovary syndrome and normal prolactin level

Objective: The purpose of this study was to examine the effects of of bromocriptin combined with clomiphene citrate in clomiphene-resistant patients with polycystic ovary syndrome and normal prolactin level. Design: Prospective, double-blind, controlled study. Setting: University teaching hospital. Patients: One hundred polycystic ovary patients and normal prolactin (PRL) who were clomiphene citrate resistant. Interventions: Treatment group received 150 mg clomiphene citrate on days 5–9 and 7.5 mg bromocriptin continuously. Control group received the same protocol of clomiphene citrate combined with placebo. Main outcome measures: Hormonal status, follicular monitoring, ovulation rate. Results: Follicular development (follicular size greater than 15 mm) was observed in 12 (25.5%) and eight (15.1%) women in treatment and placebo group respectively (P=0.29). The serum prolactin level was within normal limits in all patients before treatment. After 3 and 6 months of treatment with bromocriptin, there was a significant decrease in serum level of prolactin (P=0.000001).No any significant differences was seen in ovulation, and serum levels of follicle-stimulating hormone (FSH), luteinizing hormone (LH), dehydroepiandrosterone sulfate (DHEAS), progesterone (P) between treatment and placebo group after treatment. Conclusions: The only significant effect of long-term bromocriptin therapy in clomiphene citrate resistant polycystic ovary women was to lower the serum prolactin concentration. It was also concluded that 10–15% of patients with polycystic ovaries experienced occasional ovulatory cycles and pregnancy whether or not they were on treatment. This work was performed at the Division of Infertility, Department of Obstetrics and Gynecology, School of Medicine, Shiraz University of Medical Sciences, Shiraz, Iran.     

Association between self-reported childhood socioeconomic position and adult lung function: findings from the British Women's Heart and Health Study

BACKGROUND: A study was undertaken to assess the associations between indicators of early life socioeconomic position and lung function in older adulthood. METHODS: The associations of self-reported indicators of childhood socioeconomic position with adult lung function (forced expiratory volume in 1 second (FEV(1)), forced vital capacity (FVC), and forced expiratory flow rate during mid expiration (FEF(25-75)), all measured using standard procedures) were assessed in a cross sectional study of 3641 British women aged 60-79 years. RESULTS: In confounder adjusted analyses, each individual indicator of childhood circumstances was inversely associated with each measure of lung function. In the fully adjusted models (including mutual adjustment for each of the other indicators of childhood socioeconomic circumstances), only childhood occupational social class and access to a car were associated with lung function in adulthood. However, there were strong linear trends of worsening lung function with greater numbers of indicators of childhood poverty (all p values <0.001). CONCLUSIONS: Childhood poverty is associated with poorer lung function in women aged 60-79 years. Adverse childhood circumstances that affect both lung growth and development and cardiovascular disease in later life may explain some of the well known associations between poor lung function and cardiovascular disease, or lung function may be an important mediating factor in this association.     

Anesthetic management of a patient with congenital methemoglobinemia

A knowledge of congenital methemoglobinemia is essential to deliver a safe anesthetic to this group of patients. We report the case of a 33-year-old patient with congenital methemoglobinemia undergoing a gynecological procedure, and discuss the anesthetic implications. The etiology, pathophysiology, classification, diagnosis, clinical manifestations, anesthetic considerations, treatment options, and postoperative management are also discussed.
