Symptom Relief and Side Effects of Postmenopausal Hormones: Results From the Postmenopausal Estrogen/Progestin Interventions Trial

Objective To assess pair-wise differences between placebo, estrogen, and each of three estrogen-progestin regimens on selected symptoms. Methods This was a 3-year, multicenter, double-blind, placebo-controlled trial in 875 postmenopausal women aged 45–64 years at baseline. Participants were assigned randomly to one of five groups: 1) placebo, 2) daily conjugated equine estrogens, 3) conjugated equine estrogens plus cyclical medroxyprogesterone acetate, 4) conjugated equine estrogens plus daily medroxyprogesterone acetate, and 5) conjugated equine estrogens plus cyclical micronized progesterone. Symptoms were self-reported using a checklist at 1 and 3 years. Factor analysis reduced 52 symptoms to a set of six symptom groups. Results In intention-to-treat analyses at 1 year, each active treatment demonstrated a marked, statistically significant, protective effect against vasomotor symptoms compared with placebo (odds ratios [ORs] 0.17–0.28); there was no additional benefit of estrogen-progestin over estrogen alone. Only progestin-containing regimens were significantly associated with higher levels of breast discomfort (OR 1.92–2.27). Compared with placebo, women randomized to conjugated equine estrogens reported no increase in perceived weight. Those randomized to medroxyprogesterone acetate reported less perceived weight gain (OR 0.61–0.69) than placebo. Anxiety, cognitive, and affective symptoms did not differ by treatment assignment. Analyses restricted to adherent women were not materially different than those using intention-to-treat, except that women adherent to medroxyprogesterone acetate and micronized progesterone regimens reported fewer musculoskeletal symptoms (OR 0.62–0.68). Conclusion These results confirm the usefulness of postmenopausal hormone therapy for hot flashes, show convincingly that estrogen plus progestin causes breast discomfort, and demonstrate little influence of postmenopausal hormones on anxiety, cognition, or affect.

Analysis of complications in patients with endometrial carcinoma receiving adjuvant irradiation

We analyzed the complications in 310 patients with pathologically documented endometrial carcinoma who received adjuvant radiation therapy (RT) at Fox Chase Cancer Center between 1970 and 1986. Variables included timing of treatment, technique, total dose, age, diabetes, previous abdominal surgery, hypertension, prior bowel pathology, and lymphadenectomy. According to the FIGO (1985) system, 258 patients had Stage I disease, 48 had Stage II, and one had Stage III. One hundred seventy patients received preoperative (preop) RT, 138 received postoperative (postop) RT, and 2 received preop and postop RT. A 4-field technique was used for 212 of 235 patients receiving external-beam (EX) RT, and 75 patients were treated with intracavitary (IC) RT only. Median follow-up was 5.5 years. Actuarial survival of all 310 patients was 78% at 5 years. Thirty-two complications occurred, involving the rectum, small bowel, femur, or lower extremity. Complications were graded according to the ECOG scoring system as grade 2 (mild) and grades 3, 4, or 5 (serious). One of 75 patients treated with IC RT only experienced a grade-2 complication (proctitis). Of 71 patients receiving 4-field EX RT only, 25 preop (16%) and 14 postop (14%) patients had complications. Of 139 patients treated with both EX and IC RT, grade-2 complications were seen in 5% of 87 preop patients and 12% of 52 postop patients (p = 0.17), whereas serious complications were observed in 4% of each group. Univariate analysis of the variables of interest revealed that the incidence of complications was associated with a lymphadenectomy (p = .03), use of external RT (p less than .01), and decreasing age (p = .04). Multivariate analysis confirmed that use of external RT was the most significant predictor for complications. In conclusion, similar complication rates were found in patients treated with either preop or postop 4-field EX RT. While pelvic RT clearly decreases pelvic relapse in patient with endometrial carcinoma, the risk benefit ratio for treatment of these patients should be carefully considered when recommending adjuvant RT for pelvic control.

Weight loss prevents urinary incontinence in women with type 2 diabetes: results from the Look AHEAD trial.

PURPOSE We determined the effect of weight loss on the prevalence, incidence and resolution of weekly or more frequent urinary incontinence in overweight/obese women with type 2 diabetes after 1 year of intervention in the Look AHEAD (Action for Health in Diabetes) trial. MATERIALS AND METHODS Women in this substudy (2,739, mean ± SD age 57.9 ± 6.8 years, body mass index 36.5 ± 6.1 kg/m(2)) were randomized into an intensive lifestyle weight loss intervention or a diabetes support and education control condition. RESULTS At baseline 27% of participants reported urinary incontinence on a validated questionnaire (no significant difference by intensive lifestyle intervention vs diabetes support and education). After 1 year of intervention the intensive lifestyle intervention group in this substudy lost 7.7 ± 7.0 vs 0.7 ± 5.0 kg in the diabetes support and education group. At 1 year fewer women in the intensive lifestyle intervention group reported urinary incontinence (25.3% vs 28.6% in the diabetes support and education group, p = 0.05). Among participants without urinary incontinence at baseline 10.5% of intensive lifestyle intervention and 14.0% of diabetes support and education participants experienced urinary incontinence after 1 year (p = 0.02). There were no significant group differences in the resolution of urinary incontinence (p >0.17). Each kg of weight lost was associated with a 3% reduction in the odds of urinary incontinence developing (p = 0.01), and weight losses of 5% to 10% reduced these odds by 47% (p = 0.002). CONCLUSIONS Moderate weight loss reduced the incidence but did not improve the resolution rates of urinary incontinence at 1 year among overweight/obese women with type 2 diabetes. Weight loss interventions should be considered for the prevention of urinary incontinence in overweight/obese women with diabetes.

Postmenopausal hormone therapy and cognitive outcomes: The Women's Health Initiative Memory Study (WHIMS)

This review discusses major findings from the Womens Health Initiative Memory Study (WHIMS). WHIMS reported hormone therapy (HT)--conjugated equine estrogen (CEE) with or without medroxyprogesterone acetate (MPA)--increased the risk for dementia (HR 1.76 [95% CI, 1.19-2.60]; P=0.005) and global cognitive decline, with a mean decrement relative to placebo of 0.21 points on the Modified Mini Mental State Examination (3MS) (P=0.006) in women age 65 and older. A subset of WHIMS participants joined the ancillary WHI Study of Cognitive Aging (WHISCA) trials, in which domain-specific cognitive tests and mood were measured annually. Compared with placebo, CEE+MPA had a negative impact on verbal memory over time (P=0.01); and CEE-Alone was associated with lower spatial rotational ability (P < or = 0.01) at the initial assessment, but the difference diminished over time. The ancillary WHIMS-MRI study measured subclinical cerebrovascular disease to possibly explain the negative cognitive findings reported by WHIMS and the increased clinical stroke in older women reported by the WHI. WHIMS-MRI reported that while CEE+MPA and CEE-Alone were not associated with increased ischemic brain lesion volume relative to placebo; both CEE+MPA and CEE-Alone were associated with lower mean brain volumes in the hippocampus (P=0.05); frontal lobe (P=0.004); and total brain (P=0.07). HT-associated reductions in hippocampal volumes were greatest in women with baseline 3MS scores < or = 90.

Postmenopausal hormone therapy and subclinical cerebrovascular disease: The WHIMS-MRI Study

Objective: The Womens Health Initiative Memory Study (WHIMS) hormone therapy (HT) trials reported that conjugated equine estrogen (CEE) with or without medroxyprogesterone acetate (MPA) increases risk for all-cause dementia and global cognitive decline. WHIMS MRI measured subclinical cerebrovascular disease as a possible mechanism to explain cognitive decline reported in WHIMS. Methods: We contacted 2,345 women at 14 WHIMS sites; scans were completed on 1,424 (61%) and 1,403 were accepted for analysis. The primary outcome measure was total ischemic lesion volume on brain MRI. Mean duration of on-trial HT or placebo was 4 (CEE+MPA) or 5.6 years (CEE-Alone) and scans were conducted an average of 3 (CEE+MPA) or 1.4 years (CEE-Alone) post-trial termination. Cross-sectional analysis of MRI lesions was conducted; general linear models were fitted to assess treatment group differences using analysis of covariance. A (two-tailed) critical value of α = 0.05 was used. Results: In women evenly matched within trials at baseline, increased lesion volumes were significantly related to age, smoking, history of cardiovascular disease, hypertension, lower post-trial global cognition scores, and increased incident cases of on- or post-trial mild cognitive impairment or probable dementia. Mean ischemic lesion volumes were slightly larger for the CEE+MPA group vs placebo, except for the basal ganglia, but the differences were not significant. Women assigned to CEE-Alone had similar mean ischemic lesion volumes compared to placebo. Conclusions: Conjugated equine estrogen–based hormone therapy was not associated with a significant increase in ischemic brain lesion volume relative to placebo. This finding was consistent within each trial and in pooled analyses across trials.

Influence of type 2 diabetes on brain volumes and changes in brain volumes: Results from the Women's Health Initiative Magnetic Resonance Imaging Studies

OBJECTIVE To study how type 2 diabetes adversely affects brain volumes, changes in volume, and cognitive function. RESEARCH DESIGN AND METHODS Regional brain volumes and ischemic lesion volumes in 1,366 women, aged 72–89 years, were measured with structural brain magnetic resonance imaging (MRI). Repeat scans were collected an average of 4.7 years later in 698 women. Cross-sectional differences and changes with time between women with and without diabetes were compared. Relationships that cognitive function test scores had with these measures and diabetes were examined. RESULTS The 145 women with diabetes (10.6%) at the first MRI had smaller total brain volumes (0.6% less; P = 0.05) and smaller gray matter volumes (1.5% less; P = 0.01) but not white matter volumes, both overall and within major lobes. They also had larger ischemic lesion volumes (21.8% greater; P = 0.02), both overall and in gray matter (27.5% greater; P = 0.06), in white matter (18.8% greater; P = 0.02), and across major lobes. Overall, women with diabetes had slightly (nonsignificant) greater loss of total brain volumes (3.02 cc; P = 0.11) and significant increases in total ischemic lesion volumes (9.7% more; P = 0.05) with time relative to those without diabetes. Diabetes was associated with lower scores in global cognitive function and its subdomains. These relative deficits were only partially accounted for by brain volumes and risk factors for cognitive deficits. CONCLUSIONS Diabetes is associated with smaller brain volumes in gray but not white matter and increasing ischemic lesion volumes throughout the brain. These markers are associated with but do not fully account for diabetes-related deficits in cognitive function.

Prevalence and Risk Factors for Urinary Incontinence in Overweight and Obese Diabetic Women: Action for Health in Diabetes (Look AHEAD) study

OBJECTIVE To determine the prevalence and risk factors for urinary incontinence among different racial/ethnic groups of overweight and obese women with type 2 diabetes. RESEARCH DESIGN AND METHODS Cross-sectional analysis of baseline data from the Action for Health in Diabetes (Look AHEAD) study, a randomized clinical trial with 2,994 overweight/obese women with type 2 diabetes. RESULTS Weekly incontinence (27%) was reported more often than other diabetes-associated complications, including retinopathy (7.5%), microalbuminuria (2.2%), and neuropathy (1.5%). The prevalence of weekly incontinence was highest among non-Hispanic whites (32%) and lowest among African Americans (18%), and Asians (12%) (P < 0.001). Asian and African American women had lower odds of weekly incontinence compared with non-Hispanic whites (75 and 55% lower, respectively; P < 0.001). Women with a BMI of ≥35 kg/m2 had a higher odds of overall and stress incontinence (55–85% higher; P < 0.03) compared with that for nonobese women. Risk factors for overall incontinence, as well as for stress and urgency incontinence, included prior hysterectomy (40–80% increased risk; P < 0.01) and urinary tract infection in the prior year (55–90% increased risk; P < 0.001). CONCLUSIONS Among overweight and obese women with type 2 diabetes, urinary incontinence is highly prevalent and far exceeds the prevalence of other diabetes complications. Racial/ethnic differences in incontinence prevalence are similar to those in women without diabetes, affecting non-Hispanic whites more than Asians and African Americans. Increasing obesity (BMI ≥35 kg/m2) was the strongest modifiable risk factor for overall incontinence and stress incontinence in this diverse cohort.

Binge eating and weight loss outcomes in overweight and obese individuals with type 2 diabetes: results from the Look AHEAD trial.

CONTEXT Binge eating (BE) is common in overweight and obese individuals with type 2 diabetes mellitus, but little is known about how BE affects weight loss in this population. OBJECTIVE To determine whether BE was related to 1-year weight losses in overweight and obese individuals with type 2 diabetes participating in an ongoing clinical trial. DESIGN, SETTING, AND PARTICIPANTS The Look AHEAD (Action for Health in Diabetes) trial is a randomized controlled trial examining the long-term effect of intentional weight loss on cardiovascular disease in overweight and obese adults with type 2 diabetes. A total of 5145 overweight and obese individuals aged 45 to 76 years with type 2 diabetes participated in this study. INTERVENTIONS Participants were randomly assigned to an intensive lifestyle intervention or to enhanced usual care (a diabetes support and education control condition). MAIN OUTCOME MEASURES At baseline and 1 year, participants had their weight measured and completed a fitness test and self-report measures of BE and dietary intake. Four groups were created based on BE status at baseline and 1 year (yes/yes, no/no, yes/no, and no/yes). Analyses controlled for baseline differences between binge eaters and non-binge eaters. RESULTS Most individuals (85.4%) did not report BE at baseline or 1 year (no/no), 7.5% reported BE only at baseline (yes/no), 3.7% reported BE at both times (yes/yes), and 3.4% reported BE only at 1 year (no/yes), with no differences between intensive lifestyle intervention and diabetes support and education conditions (P = .14). Across intensive lifestyle intervention and diabetes support and education, greater weight losses were observed in participants who stopped BE at 1 year (mean [SE] weight loss, 5.3 [0.4] kg) and those who reported no BE at either time (mean [SE] weight loss, 4.8 [0.1] kg) than in those who continued BE (mean [SE] weight loss, 3.1 [0.6] kg) and those who began BE at 1 year (mean [SE] weight loss, 3.0 [0.6] kg) (P < .001). Post hoc analyses suggested that these differences were due to changes in caloric intake. CONCLUSION Overweight and obese individuals with type 2 diabetes who stop BE appear to be just as successful at weight loss as non-binge eaters after 1 year of treatment.
