Involvement of interleukin-1 and the interleukin-1 receptor antagonist in in vitro embryo development among women undergoing in vitro fertilization-embryo transfer.

PURPOSE: To examine the roles of Interleukin-1 (IL-1) and IL-1 receptor antagonist (IL-1ra), in in vitro embryo development and subsequent pregnancy outcome. METHODS: Maternal serum utilized to supplement embryo growth in IVF cycles was analyzed for the presence of IL-1 cytokines. RESULTS: The maternal serum that was utilized to supplement the embryo media was found to have measurable amounts of IL-1beta and IL-1ra. CONCLUSIONS: Relative antagonism of the IL-1 system was positively associated with embryo development and pregnancy outcome.

A prospective study on the risk of cervical intra-epithelial neoplasia among healthy subjects with serum antibodies to HPV compared with HPV DNA in cervical smears.

To estimate the risk of developing cervical intra-epithelial neoplasia (CIN) among women exposed to human papillomavirus (HPV) type 16, we performed a prospective study in a population-based cohort of more than 15,000 women followed for 34.9 months. Seventy-four women developed CIN during follow-up and were matched for age, time of sampling and area of residence with 148 women who remained CIN-free during follow-up. The blood samples taken at enrollment were tested for serum antibodies to HPV types 16, 18 and 33 capsids. Cervical smears or biopsies were analyzed for the presence of HPV DNA by nested PCR using HPV general primers and by HPV 16- and 18-type-specific PCR HPV serology and HPV-PCR were in good agreement, particularly when the blood sample and the Pap smear were taken less than 6 months apart. HPV DNA was found in 88% of cases and 4% of controls, whereas HPV 16 DNA was present in 44% of cases and in 1 of 142 controls. HPV-16-seropositive women had a 3-fold increased risk of developing CIN. The risk was highest among women younger than 35 years of age, of whom an estimated 3.4% of HPV-16-seropositive and 0.5% of seronegative women developed CIN. Since the risk associated with HPV-16 seropositivity (a measure of past or present infection) was 35-fold lower than that of HPV DNA (present infection), most infections appear to be eliminated before CIN develops. In conclusion, HPV 16 infection does confer an excess risk of CIN development, and HPV DNA detection has a high predictive value for the presence of high-grade CIN.

Economic development and women's blood pressure: field evidence from rural Mashonaland, Zimbabwe.

A survey of 515 non-pregnant women at 12 geographically chosen research sites in rural Mashonaland shows significant differences in mean blood pressure, controlled by age cohorts. Three levels of economic development are identified: (1) the traditional economy on communal lands, with lowest blood pressure, (2) the wage economy in areas of large-scale commercial agriculture, with elevated blood pressure and (3) the wage economy in mining areas, with the highest elevation of blood pressure. The area is dominated by the primate city, Harare, up to distances of 300 km and beyond, from which forces of change and modernization emanate. It is seen that potassium, sodium and the sodium potassium ratio, are distance-related to Harare and that women's blood pressures tend to follow suit. The rise of body sodium in young persons at risk, often accompanied by declining potassium intake and other changes of modernization, suggest that more attention should be focused on rural areas in Africa, now in the throes of economic change.

Serum antibody response to the heat shock protein 60 of Chlamydia trachomatis in women with developing cervical cancer.

OBJECTIVE: The purpose of this study was to determine whether serum antibody response to the three versions of chlamydial heat shock protein 60 is associated with an increased risk for cervical cancer. STUDY DESIGN: Women with cervical carcinoma were identified by linking the data files of three Nordic serum banks with cancer registries. Overall, 178 women with invasive cervical carcinoma were identified. For each case, the earliest prediagnostic serum sample was chosen, and three matched control subjects who were free of cancer at the time of the case diagnosis were selected randomly. Serum antibodies to the chlamydial heat shock protein 60 were measured by enzyme-linked immunosorbent assay and correlated with the risk of the subsequent development of cervical cancer. RESULTS: Antibodies to chlamydial heat shock protein 60-1 were associated with cervical squamous cell carcinoma among cases with long lag time (>3.5 years; odds ratio, 2.4; 95% CI, 1.1-5.1). Antibodies to chlamydial heat shock protein 60-2 or chlamydial heat shock protein 60-3 were not associated with cervical cancer risk. CONCLUSIONS: The finding that chlamydial heat shock protein 60-1 antibodies are associated with an increased cervical cancer risk suggests that persistent Chlamydia trachomatis infection may contribute to cervical neoplasia.

Hormone replacement therapy prevents osteoclastic hyperactivity: A histomorphometric study in early postmenopausal women.

In a randomized, double blind, clinical prospective trial comprising 35 women treated with either hormone replacement therapy (HRT) (cyclic estradiol/norethisterone acetate) or placebo we performed histomorphometric studies on paired bone biopsies obtained before and after 2 years of treatment. Untreated women developed a progressively more negative balance at individual bone multicellular units (BMUs) (i.e., wall thickness-erosion depth) (2.2 +/- 1.7 microm vs. -5.7 +/- 1.4 microm; p < 0.01), while women on HRT displayed preservation of bone balance (2.4 +/- 2.4 microm vs. 2.5 +/- 2.5 microm; NS). No significant differences in wall thickness between the two groups were demonstrable, but the untreated women developed a pronounced increase in erosion depth over 2 years (46.9 +/- 1.8 microm vs. 52.0 +/- 1.9 microm; p < 0.05), while the HRT group revealed no change (47.8 +/- 2.7 microm vs. 44.6 +/- 1.7 microm; NS). Furthermore, the placebo group displayed an increased osteoclastic erosion depth (17.8 +/- 1.6 microm vs. 25.0 +/- 1.7 microm; p < 0.001), compared with unchanged values in the HRT group (20.0 +/- 1.6 microm vs. 16.9 +/- 1.4 microm/day; NS). While the placebo group revealed a slight increase in volume referent resorption rate (35 +/- 8% vs. 38 +/- 8%; NS) the HRT group revealed a pronounced decrease (46 +/- 8% vs. 28 +/- 5%; p < 0.05). No significant changes in marrow star volume (an index of trabecular perforations) were demonstrable in either group. Our results demonstrate that bone remodeling in early postmenopausal women is characterized by progressive osteoclastic hyperactivity, which is reduced by cyclic HRT. This reduction of resorptive activity at the BMU level after HRT seems to precede the reduction in activation frequency demonstrated in previous studies on older postmenopausal women.

Incidence of breast abscess in lactating women: report from an Australian cohort.

OBJECTIVES: To report the incidence of breast abscess in lactating women. DESIGN: Data were combined from two studies (a randomised controlled trial and a survey) to provide a cohort of women for this report. SETTING: Women were recruited from two hospitals on one site in Melbourne, Victoria, the Royal Women's Hospital (public) (1999-2001) and Frances Perry House (private) (2000-2001). PARTICIPANTS: A total of 1193 of 1311 (91%) primiparous, English-speaking women from a diverse range of backgrounds, including those receiving public clinic care, private care and birth centre care. METHODS: A structured telephone interview was conducted on breastfeeding at six months postpartum. MAIN OUTCOME MEASURES: Lactational mastitis and breast abscess. RESULTS: Two hundred and seven women experienced mastitis. Five women developed a breast abscess: 0.4% of women who commenced breastfeeding (95% CI 0.14-0.98); 2.9% of women who took antibiotics for mastitis (95% CI 1.0-6.7). CONCLUSION: Although many authors estimate that 11% of women with mastitis develop a breast abscess, the incidence of lactating breast abscesses in Australia appears to be lower than reported in the past. Our estimate is that 3% of women with mastitis will develop a breast abscess.

Activity of platelet-activating-factor-acetylhydrolase and the nitric oxide metabolite level in the plasma of pregnant women who develop transient hypertension during later pregnancy.

It is reported that plasma platelet-activating-factor-acetylhydrolase (PAF-AH) is elevated in patients with essential hypertension. In this study, plasma PAF-AH activity was measured during pregnancy and after delivery to examine the relationship between plasma PAF-AH activity and the development of transient hypertension (TH) during pregnancy. Moreover, in order to examine the involvement of endothelial injury in TH, the plasma level of nitric oxide metabolite (NOx; NO2+NO3) was measured. The plasma PAF-AH activity in 51 pregnant women was consecutively measured in the 1st, 2nd and 3rd trimesters of gestation, and after delivery. Forty-one cases were normal pregnancies and 10 cases were complicated by TH later during pregnancy. The PAF-AH activity in the normal pregnancy group decreased in the 2nd trimester of gestation compared with the 1st trimester, but was elevated in the TH group. The incidence of elevation of PAF-AH in the TH group was significantly (7/10; 70.0%; P<0.01, Chi-squared test) higher than in the normal pregnancy group (9/41; 22.0%). The plasma NOx levels in the 2nd trimester were higher than those in the 1st trimester in both the normotensive and TH group (P<0.05 for both comparisons). The 51 patients were classified into two groups according to the change in the PAF-AH in the 2nd trimester: group A consisted of 35 patients whose PAF-AH activity did not increase, and group B consisted of 16 patients whose PAF-AH activity increased. The incidence of development of TH during later pregnancy in group B was significantly (7/16; 43.8%; P<0.01, Chi-squared test) higher than in group A (3/35; 8.6%). Hypertension developed after 36 weeks' gestation in all patients in the TH group. The results of the present study suggest that changes in PAF metabolism may relate to regulation of blood pressure in pregnant women whose pregnancy is complicated with TH, whereas NO metabolism does not differ between women with TH and those having a normal pregnancy.

Postpartum rubella immunization: association with development of prolonged arthritis, neurological sequelae, and chronic rubella viremia.

Six women developed chronic long-term arthropathy after postpartum immunization against rubella. All individuals developed acute polyarticular arthritis within 12 days to three weeks postimmunization and have had continuing chronic or recurrent arthralgia or arthritis for two to seven years after vaccination. Acute neurological manifestations, consisting of carpal tunnel syndrome or multiple paresthesiae, developed postvaccination in three women. Two have developed continuing active or chronic recurrent episodes of blurred vision, paresthesiae, and painful limb syndromes together with recurrent joint symptoms. Chronic rubella viremia has been detected in peripheral blood mononuclear cell (MNC) populations in five of the six women up to six years after vaccination. In addition rubella virus was isolated from breast milk MNCs in one individual at nine months postvaccination and from peripheral blood MNCs in two of four breast-fed infants studied at 12-18 months of age. Immune responses to rubella virus studied at sequential intervals after vaccination correlated with development of rheumatologic and neurological manifestations.

Choline: critical role during fetal development and dietary requirements in adults.

Choline is an essential nutrient needed for the structural integrity and signaling functions of cell membranes; for normal cholinergic neurotransmission; for normal muscle function; for lipid transport from liver; and it is the major source of methyl groups in the diet. Choline is critical during fetal development, when it influences stem cell proliferation and apoptosis, thereby altering brain and spinal cord structure and function and influencing risk for neural tube defects and lifelong memory function. Choline is derived not only from the diet, but from de novo synthesis as well. Though many foods contain choline, there is at least a twofold variation in dietary intake in humans. When deprived of dietary choline, most men and postmenopausal women developed signs of organ dysfunction (fatty liver or muscle damage), while less than half of premenopausal women developed such signs. Aside from gender differences, there is significant variation in the dietary requirement for choline that can be explained by very common genetic polymorphisms.
