Demographic, family, and occupational characteristics associated with major depression: the Harvard study of moods and cycles

OBJECTIVE

This study assesses the extent to which women with and without major depression differ by demographic, familial, and occupational characteristics.

METHOD

From a community-based sample, the authors identified 332 women with and 644 women without current or past major depression based on Structured Clinical Interviews for DSM-IV. Demographic and background interviews were conducted in-person.

RESULTS

Depressed women were more likely to have gained >or =35 lbs between age 18 and study enrollment (OR=1.6, 95% CI 1.1-2.5), experienced divorce (OR=2.0, 95% CI 1.4-2.8), or changed occupations (OR=1.5, 95% CI 1.1-2.1) compared with non-depressed women. Compared with women with no brothers, those with > or =1 brothers were less likely to have a history of depression (OR=0.8, 95% CI 0.6-1.1), whereas compared with women with no sisters, those with > or =1 sisters were more likely to have current or past depression (OR=1.4, 95% CI 1.0-1.9). These findings were not influenced by family sibship size.

CONCLUSION

These results illustrate demographic differences between women with and without major depression and that sibship gender rather than size may also influence risk.

Serum and follicular fluid hormone levels during in vitro fertilization after short- or long-course treatment with a gonadotropin-releasing hormone agonist

OBJECTIVE

To examine the impact of flare (short) vs. down-regulation (long) GnRH agonist (GnRH-a) on serum and follicular fluid (FF) LH and androgen concentrations in women undergoing IVF treatment cycles.

DESIGN

Prospective observational study.

SETTING

IVF clinic.

PATIENT(S)

One hundred sixteen ovulatory subjects undergoing IVF.

INTERVENTION(S)

Fifty-eight ovulatory patients undergoing a down-regulation regimen matched with 58 undergoing the flare regimen as part of an IVF cycle.

MAIN OUTCOME MEASURE(S)

Serum concentrations of LH, FSH, Progesterone (P4), Androstenedione (A), T, and E(2) on the day of hCG administration were compared between the two groups. In addition, the FF P4, 17OHP4, A, T, and E(2) levels were compared in the two groups.

RESULT(S)

Serum LH was significantly higher with the flare regimen (15.2 +/- 1.14 IU/L, P<.05) when compared with results with the down-regulation protocol (9.5 +/- 0.77 IU/L). In addition, FF A was significantly higher in the flare protocol (57.3 +/- 13.3 ng/mL, P<.05) compared with in the down-regulation protocol (27 +/- 2.44 ng/mL). Serum and FF P4, 17OH P4, T, and E(2) were not statistically significantly different between the two groups.

CONCLUSION(S)

Serum LH and FF A are significantly higher in the flare regimen in comparison with the down-regulation regimen. Circulating LH appears to play a role in determining FF A concentration.

Complications of hysteroscopic surgery: predicting patients at risk

OBJECTIVE

To determine the frequency of operative complications and whether they can be predicted by specific patient characteristics or type of hysteroscopic procedure.

METHODS

We collected demographic and medical history information on 925 women who had hysteroscopies from 1995 through 1996. We compared differences in rates of operative complications of specific hysteroscopic procedures. Operative complications were defined as uterine perforation, excessive glycine absorption (1 L or more), hyponatremia, hemorrhage (500 mL or more), bowel or bladder injury, inability to dilate the cervix, and procedure-related hospital admissions.

RESULTS

Operative complications occurred in 25 (2.7%) of 925 hysteroscopies. Excessive fluid absorption was the most frequent complication. Hysteroscopic myomectomy and resection of uterine septum were associated with greater odds of complications (odds ratio [OR] 7.4, 95% confidence interval [CI] 3.3, 16.6 and OR 4.0, 95% CI 0.9, 19.6, respectively). Hysteroscopic polypectomy and endometrial ablation were associated with lower odds of complications (OR 0.1, 95% CI 0.0, 0.7 and OR 0.4, 95% CI 0.1, 3.3, respectively). Hysteroscopies done by reproductive endocrinologists and preoperative GnRH agonist therapy were associated with 4-7 times higher odds for operative complications.

CONCLUSION

Complications during hysteroscopic surgery are rare. Among hysteroscopic procedures, myomectomies and resections of uterine septa have significantly higher rates of complications, especially excessive fluid absorption. Meticulous fluid management might limit the number of serious complications of these higher-risk procedures.

Predictive value of serum and follicular fluid leptin concentrations during assisted reproductive cycles in normal women and in women with the polycystic ovarian syndrome

Leptin is an adipocyte-derived hormone which plays a central role in the regulation of body weight and energy homeostasis and in signalling to the brain that adequate energy stores are available for reproduction. Although leptin may affect reproduction by regulating the hypothalamic-pituitary-gonadal axis, recent in-vitro observations indicate that leptin may also have direct intra-ovarian actions. Leptin concentrations were measured in women who succeeded in becoming pregnant within three cycles of in-vitro fertilization (IVF) or gamete intra-fallopian transfer (n = 53), in women who failed to become pregnant within three cycles (n = 50), and in women with polycystic ovarian syndrome (PCOS) (n = 22). It was found that lower follicular fluid leptin concentrations were a marker of assisted reproduction treatment success in normal women. Women with PCOS had higher leptin concentrations than women without such a diagnosis, but this was due to their higher body mass index (BMI). After adjustment for age and BMI, women with PCOS who became pregnant tended to have lower mean follicular fluid leptin concentrations than women with PCOS who did not succeed at becoming pregnant. Further studies exploiting the strengths of the IVF model are needed to assess whether the prognostic role for follicular fluid leptin in human reproduction is independent of other factors, and to elucidate the underlying mechanisms.

Recent trends in assisted reproductive techniques and associated outcomes

OBJECTIVE

We examined recent trends in success rates for assisted reproduction and determined the influence of changes in patient selection and treatment characteristics on these trends.

METHODS

We collected baseline information and abstracted treatment-related details and outcomes on 1244 couples accepted for in vitro fertilization (IVF) or gamete intrafallopian transfer (GIFT) at three clinics in greater Boston from 1994-1998.

RESULTS

Delivery rates per initiated cycle improved significantly from 14.9% for IVF and 20.6% for GIFT in 1994-1995 to 22.5% for IVF and 28.0% for GIFT in 1997-1998 (P < or = .001). After adjusting for female age, the two treatment-related variables that appeared most likely to explain this trend were decreased use of GnRH agonists in short course (flare) regimens and increased use of highly purified forms of urinary gonadotropins.

CONCLUSION

There were significant improvements in the success rates for IVF and GIFT from 1994-1998 that correlated with changes in ovulation induction regimens.

A case-control study of galactose consumption and metabolism in relation to ovarian cancer

Consumption or metabolism of dairy sugar and ovarian cancer have been linked based on evidence that galactose may be toxic to ovarian germ cells and that ovarian cancer is induced in animals by depletion of oocytes. We assessed consumption of dairy products and obtained blood for biochemical and molecular genetic assessment of galactose metabolism in 563 women with newly diagnosed epithelial ovarian cancer and 523 control women selected either by random digit dialing or through lists of residents in eastern Massachusetts and New Hampshire. We observed no significant differences between cases and controls in usual consumption of various types of dairy products or total daily lactose (the principal source of galactose in the diet); nor did we find that RBC activity of either galactose-1-phosphate uridyl transferase (GALT) or galactokinase differed. The mean (and SE) activity of uridine diphospho-galactose 4'-epimerase (in micromoles per hour per gram of hemoglobin) was, however, significantly lower (P < 0.005) in cases compared with controls, 20.32 (0.31) versus 21.64 (0.36). Ovarian cancer cases were also more likely to carry the N314D polymorphism of the GALT gene, generally predisposing to lower GALT activity. The difference was most evident for endometrioid and clear cell types of ovarian cancer, in which 3.9% of cases were found to be homozygous for N314D compared with 0.4% of controls, yielding an odds ratio and 95% confidence interval of 14.17 (2.62-76.60). We conclude that, whereas adult consumption of lactose carries no clear risk for the disease, certain genetic or biochemical features of galactose metabolism may influence disease risk for particular types of ovarian cancer.

Gonadotropin-releasing hormone agonist use in assisted reproduction cycles: the influence of long and short regimens on pregnancy rates

OBJECTIVE

To compare the efficacy of GnRH agonists used in either the flare (short) or down-regulation (long) regimen as part of IVF or GIFT treatment cycles.

DESIGN

Observational study.

SETTING

Three IVF clinics.

PATIENT(S)

One thousand two hundred forty-four couples accepted for IVF or GIFT treatment at participating clinics.

INTERVENTION(S)

In vitro fertilization or GIFT protocols standard to each clinic were recorded.

MAIN OUTCOME MEASURE(S)

Treatment cycle characteristics and outcomes, including E2 level, number of oocytes retrieved, and clinical pregnancy rate.

RESULT(S)

At site 1, there were 146 clinical pregnancies in 980 flare cycles, for a pregnancy rate of 14.9%, compared with 148 clinical pregnancies in 650 down-regulation cycles, for a pregnancy rate of 22.8%. This difference persisted after adjustment for age, primary infertility diagnosis, GIFT or IVF therapy, and year of treatment, and appeared to be mediated largely by the number of oocytes retrieved (mean, 9.8 for downregulation and 8.7 for flare in the first cycle). Despite having fewer oocytes retrieved, women who received flare regimens had higher E2 levels before hCG administration.

CONCLUSION(S)

Women who received GnRH agonists in a flare regimen had 11% fewer oocytes retrieved and a 35% reduction in the clinical pregnancy rate compared with those who received them in a down-regulation regimen; this difference was not explained by patient selection factors.

Genital talc exposure and risk of ovarian cancer

Epidemiologic studies have suggested an increased risk for ovarian cancer associated with the use of talcum powder in genital hygiene, but the biologic credibility of the association has been questioned. We conducted a population-based case-control study in eastern Massachusetts and New Hampshire involving 563 women with newly diagnosed epithelial ovarian cancer and 523 control women selected either by random digit dialing or through lists of residents. Use of body powders was assessed through personal interview and the exposure odds ratio (OR) for the use of talc in genital hygiene was calculated. Cases were more likely than controls (45% vs. 36%) to have used talc as a body powder in some manner, and the excess was confined to patients who used talc on the perineum directly or as a dusting powder to underwear or sanitary napkins. Relative to women who never used body powder or used it only in non-genital areas, the OR (and 95% confidence interval) associated with genital exposure to talc was 1.60 (1.18 and 2. 15) after adjustment for age, study location, parity, oral contraceptive use, body mass index and family history of breast or ovarian cancer. Exposure prior to rather than after a first livebirth appeared to be more harmful, and the association was most apparent for women with invasive serous cancers and least apparent for those with mucinous tumors. We conclude that there is a significant association between the use of talc in genital hygiene and risk of epithelial ovarian cancer that, when viewed in perspective of published data on this association, warrants more formal public health warnings.

Basal hormone levels in women who use acetaminophen for menstrual pain

OBJECTIVE

To compare basal gonadotropin and estradiol levels between women using acetaminophen versus those using no or other types of analgesics.

DESIGN

Observational study.

SETTING

Three IVF clinics in greater Boston.

PATIENT(S)

Three hundred eighty-six women accepted for their first IVF treatment who completed questionnaires recording medical history, including analgesic use for menstrual pain, and who had blood drawn during the menstrual phase of a cycle before treatment.

MAIN OUTCOME MEASURE(S)

Basal FSH, LH, and estradiol.

RESULT(S)

Basal hormone levels, especially LH, were lower for women who regularly used acetaminophen compared with women who used no medication or other types of analgesics. Lower hormone levels in acetaminophen users were consistently observed when women were subdivided by age, body mass index, smoking history, and degree of menstrual pain-features that might have influenced analgesic use or hormone levels.

CONCLUSION(S)

This study provides preliminary evidence that acetaminophen may lower gonadotropin and estradiol levels and offers a biologic basis for the epidemiologic observation that acetaminophen use may reduce the risk of ovarian cancer.

Chronic pelvic pain: prevalence, health-related quality of life, and economic correlates

OBJECTIVE

To determine the prevalence of chronic pelvic pain in U.S. women aged 18-50 years, and to examine its association with health-related quality of life, work productivity, and health care utilization.

METHODS

In April and May 1994, the Gallup Organization telephoned 17,927 U.S. households to identify women aged 18-50 years who experienced chronic pelvic pain, ie, of at least 6 months' duration. Those who reported chronic pelvic pain were surveyed on severity, frequency, and diagnosis; quality of life; work loss and productivity; and health care utilization.

RESULTS

Among 5263 eligible women who agreed to participate, 773 (14.7%) reported chronic pelvic pain within the past 3 months. Those who reported chronic pelvic pain had significantly lower mean scores for general health than those who did not (70.5 versus 78.8,P<.05), and 61% of those with chronic pelvic pain reported that the etiology was unknown. Women diagnosed with endometriosis reported the most health distress, pain during or after intercourse, and interference with activities because of pain. Estimated direct medical costs for outpatient visits for chronic pelvic pain for the U.S population of women aged 18-50 years are $881.5 million per year. Among 548 employed respondents, 15% reported time lost from paid work and 45% reported reduced work productivity.

CONCLUSION

Frequently, the cause of chronic pain is undiagnosed, although it affects approximately one in seven U.S. women. Increased awareness of its cost and impact on quality of life should promote increased medical attention to this problem.
