Fertil Steril 2009; 94:1734-8. [PMID: 20004389 DOI: 10.1016/j.fertnstert.2009.10.037] [Citation(s) in RCA: 27] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2009] [Revised: 10/14/2009] [Accepted: 10/15/2009] [Indexed: 01/17/2023]
Abstract
OBJECTIVE To describe the influence of the TTTA aromatase polymorphism (TTTAn) on the relation between obesity and plasma estradiol (E(2)) in obese men. DESIGN A 2-year cohort study. SETTING Clinical research center. PATIENT(S) Severely obese men (31 who had had gastric bypass surgery and 118 controls). INTERVENTION(S) Men were genotyped for the TTTAn CYP19A1 polymorphism. Anthropomorphic measures, plasma E(2), and other hormonal levels were determined at baseline and 2-year follow-up. MAIN OUTCOMES MEASURE(S) Relationships between weight and changes in weight and plasma E(2) were examined in relation to the TTTAn polymorphism. RESULT(S) The mean age was 46.5 ± 10.82 years, and mean body mass index was 47.1 ± 8.46 kg/m(2). The most common repeats were 7 and 11. TTTAn number did not correlate with plasma E(2) in the univariate analysis. When patients were stratified per weight group, the correlation between plasma E(2) and weight was seen only among men with a higher TTTA repeat at baseline and 2 years. Similarly, only men with higher TTTA exhibited reduced E(2) levels after weight loss. CONCLUSION(S) A higher TTTA repeat is associated with a strengthened relationship between obesity and E(2). The well-established effect of increased weight on plasma E(2) appears to be absent in men with low TTTA numbers.

Abstract
Despite occupying the same habitats as mammals, having similar ranges of body mass and longevity, and facing similar pathogen challenges, birds have a different repertoire of organs, cells, molecules and genes of the immune system when compared to mammals. In other words, birds are not "mice with feathers", at least not in terms of their immune systems. Here we discuss differences between immune gene repertoires of birds and mammals, particularly those known to play a role in immune-endocrine interactions in mammals. If we are to begin to understand immune-endocrine interactions in the chicken, we need to understand these repertoires and also the biological function of the proteins encoded by these genes. We also discuss developments in our ability to understand the function of dendritic cells in the chicken; the function of these professional antigen-presenting cells is affected by stress in mammals. With regard to the endocrine system, we describe relevant chicken pituitary-adrenal hormones, and review recent findings on the expression of their receptors, as these receptors play a crucial role in modulating immune-endocrine interactions. Finally, we review the (albeit limited) work that has been carried out to understand immune-endocrine interactions in the chicken in the post-genome era.

Abstract
Background There is increasing pressure to tackle the wider social determinants of health through the implementation of appropriate interventions. However, turning these demands for better evidence about interventions around the social determinants of health into action requires identifying what we already know and highlighting areas for further development. Methods Systematic review methodology was used to identify systematic reviews (from 2000 to 2007, developed countries only) that described the health effects of any intervention based on the wider social determinants of health: water and sanitation, agriculture and food, access to health and social care services, unemployment and welfare, working conditions, housing and living environment, education, and transport. Results Thirty systematic reviews were identified. Generally, the effects of interventions on health inequalities were unclear. However, there is suggestive systematic review evidence that certain categories of intervention may impact positively on inequalities or on the health of specific disadvantaged groups, particularly interventions in the fields of housing and the work environment. Conclusion Intervention studies that address inequalities in health are a priority area for future public health research.

Abstract
BACKGROUND Preclinical evidence suggests synergy between docetaxel and irinotecan, two drugs active in esophagogastric cancer. We previously demonstrated the safety of docetaxel 35 mg/m2 and irinotecan 50 mg/m2 given on days 1 and 8 of a 21-day schedule. MATERIALS AND METHODS Patients who had unresectable/metastatic squamous cell carcinoma or adenocarcinoma of the esophagus, measurable disease, Eastern Cooperative Oncology Group performance status of zero to two, and normal bilirubin were eligible. Tumor assessment was carried out every three cycles. RESULTS We enrolled 29 chemotherapy-naive (CN) and 15 chemotherapy-exposed (CE) eligible patients. Principal toxic effects were diarrhea, neutropenia, and hyperglycemia. There were no toxic deaths. There was one early death, from myocardial infarction. Among 26 CN and assessable patients, there were seven (26.9%) with a partial response (PR) and one (3.8%) with a complete response (CR). There were two PRs and one CR among the patients with CE disease. Median time to progression for CN patients was 4.0 months and for CE patients 3.5 months. Median survival for CN eligible patients was 9.0 months and for CE patients 11.4 months. CONCLUSIONS Docetaxel-irinotecan combination given on a weekly x 2 of 3 schedule is promising in the treatment of advanced esophageal cancer.

Abstract
OBJECTIVE To map the health effects of interventions which aim to alter the psychosocial work environment, with a particular focus on differential impacts by socio-economic status, gender, ethnicity, or age. METHODS A systematic approach was used to identify, appraise and summarise existing systematic reviews (umbrella review) that examined the health effects of changes to the psychosocial work environment. Electronic databases, websites, and bibliographies, were searched from 2000-2007. Experts were also contacted. Identified reviews were critically appraised and the results summarised taking into account methodological quality. The review was conducted in the UK between October 2006 and December 2007. RESULTS Seven systematic reviews were identified. Changes to the psychosocial work environment were found to have important and generally beneficial effects on health. Importantly, five reviews suggested that organisational level psychosocial workplace interventions may have the potential to reduce health inequalities amongst employees. CONCLUSION Policy makers should consider organisational level changes to the psychosocial work environment when seeking to improve the health of the working age population.

Abstract
OBJECTIVE Given the high risk of cardiovascular disease in South Asians and the importance of inflammation in coronary heart disease we tested the hypothesis that circulating C-reactive protein (CRP) and interleukin 6 (IL-6) would be higher in healthy British born infants of South Asian origin than in infants of European origin in the first 2 years of life. STUDY DESIGN AND SETTING Infants of South Asian (n=74) and European (n=129) origin were followed prospectively from birth. Anthropometry and fasting CRP and IL-6 concentrations were measured at one or more of 3, 6, 12 and 24 months of age. RESULTS South Asian infants had a significantly lower circulating CRP compared with European infants (beta=0.63, 95% CI 0.41-0.98 mg/l, P=0.040). There was no significant change in CRP from birth to 2 years in either ethnic group so that neither infant weight nor weight gain were associated with CRP during follow-up. IL-6 concentrations were low or undetectable during follow-up in all participants. CONCLUSION In our cohort, South Asian origin infants had significantly lower markers of inflammation compared with European infants. Infant growth to age 2 years was not associated with CRP or IL-6. Inflammatory markers are not useful indices of CVD risk at this age, with such markers not being elevated as expected in South Asian infants. The timing of the rise of such markers to the levels found in adult South Asian populations needs longer prospective study.

Abstract
CONTEXT The effect of bariatric surgery on the reproductive function of obese men is not entirely elucidated. OBJECTIVE The aim of the study was to define the effect of Roux-En-Y gastric bypass surgery on the reproductive hormones and sexual function in obese men. DESIGN AND SETTING The cohort was followed for 2 yr at a clinical research center. PATIENTS Sixty-four severely obese men (22 who had gastric bypass surgery and 42 controls) participated in the study. INTERVENTION(S) Anthropometrics [weight, body mass index (BMI), and percentage body fat] and reproductive hormones were measured. The sexual quality of life was assessed using the Impact of Weight on the Quality Of Life-Lite questionnaire. MAIN OUTCOME MEASURE(S) Reproductive hormones and sexual quality of life were measured. RESULTS The mean age was 48.9 +/- 1.2 yr. At baseline, mean weight was 333.0 +/- 7.1 lb, BMI was 46.2 +/- 0.9 kg/m(2), and total testosterone was 339.9 +/- 21.32 ng/dl. BMI correlated positively with estradiol and negatively with total and free testosterone. Indices of dissatisfaction with sexual quality of life correlated positively with measures of obesity. Difficult sexual performance and low sexual desire correlated negatively with free and total testosterone (r = -0.273, P = 0.038; and r = -0.267, P = 0.042, respectively). After 2 yr, the gastric bypass surgery group had a significant decrease in BMI (-16.6 +/- 1.2 vs. -0.46 +/- 0.51 kg/m(2)) and estradiol (-8.1 +/- 2.4 vs. 1.6 +/- 1.4 pg/ml) and had an increase in total testosterone (310.8 +/- 47.6 vs. 14.2 +/- 15.3 ng/dl) and free testosterone (45.2 +/- 5.1 vs. -0.4 +/- 3.0 pg/ml). Sexual quality of life was improved after gastric bypass surgery. CONCLUSION Hormonal alterations and diminished sexual quality of life among obese men are related to degree of obesity, and both are improved after gastric bypass surgery.

Abstract
OBJECTIVE To assess the impact of FDG PET-CT on the management of patients with suspected recurrent ovarian cancer and to determine the incremental information provided by PET-CT. METHODS This was a prospective, multi-centre, cohort study. Ninety women (mean age 59.9 years; age range 35-85 years) with a previous history of treated epithelial ovarian carcinoma and suspected recurrence based on elevated CA-125, anatomical imaging or clinical symptoms were studied with FDG PET-CT across two States. Referring doctors were asked to specify a management plan pre-PET, if management was altered after PET-CT and, the impact (rated - none, low, medium, high) of PET-CT on patient management. The pre-PET management plan could include radiotherapy, chemotherapy, surgery, and 'other' including observation. Patients were followed at 6 and 12 months and clinical status, evidence of recurrence and progression were recorded. RESULTS Patients were referred by 34 individual specialists. At least 168 additional sites of disease in 61 patients (68%), not identified by conventional imaging were identified by PET-CT. In 77% the additional lesions were located below the diaphragm and most were nodal or peritoneal. PET-CT affected management in 60% (49% high, 11% medium impact). Patients where more disease was detected with PET-CT were more likely to progress in the following 12 months. CONCLUSIONS For women with previously treated ovarian carcinoma with recurrent disease, PET-CT can: a) alter management in close to 60% of patients, b) detect more sites of disease than abdominal and pelvic CT, c) is superior in the detection of nodal, peritoneal and subcapsular liver disease and d) offers the opportunity for technology replacement in this setting.

Abstract
The common femoral artery is commonly used as arterial access for a wide range of radiological and cardiological procedures. Pseudoaneurysm formation is the most common arterial complication of femoral artery catheterization, and is diagnosed using colour Doppler ultrasound. Ultrasound-guided thrombin injection has replaced ultrasound-guided compression as the first-line treatment. The practicalities of thrombin injection (technique and types of thrombin available) and other treatment options are discussed. Awareness of pseudoaneurysm formation and the treatment options allows prompt diagnosis and successful treatment.

Abstract
OBJECTIVE To characterize the demographic correlates of IVF availability and utilization. DESIGN Demographic analysis of public data. SETTING Each of the 50 states in the United States was used as a unit of analysis. PATIENT(S) Patients undergoing IVF, as demographically estimated. INTERVENTION(S) Publicly available data were collected through the Society for Assisted Reproductive Technology and the Centers for Disease Control. The US Census Bureau data were collected by using software available from the Centers for Disease Control. MAIN OUTCOME MEASURE(S) The number of physicians performing IVF and the number of IVF cycles per 100,000 reproductive-age women were used to estimate IVF availability and utilization. RESULT(S) In 2005, 1,031 providers performed 98,242 fresh IVF cycles in 430 centers. Overall availability was 2.5 IVF physicians per 100,000, and utilization was 236 IVF cycles per 100,000. Availability and utilization of IVF were highly correlated. Mean IVF availability and utilization were significantly higher in states with IVF insurance coverage. In adjusted analyses, IVF availability correlated positively with mandated insurance coverage, percentage of single persons, and median income. Utilization of IVF correlated with IVF availability, percentage urbanization, and percentage of individuals >or=25 years of age who had a bachelor's degree. CONCLUSION(S) Lower rates of IVF utilization in some states are correlated with a lack of insurance coverage and decreased availability of physicians providing this service.
