Patients' experiences with care for lung cancer and colorectal cancer: findings from the Cancer Care Outcomes Research and Surveillance ConsortiumPURPOSE: To assess patients' experiences with cancer care, ratings of their quality of care, and correlates of these assessments. PATIENTS AND METHODS: For 4,093 patients with lung cancer and 3,685 patients with colorectal cancer in multiple US regions and health care delivery systems, we conducted telephone surveys of patients or their surrogates in English, Spanish, or Chinese at 4 to 7 months after diagnosis. The surveys assessed ratings of the overall quality of cancer care and experiences with three domains of interpersonal care (physician communication, nursing care, and coordination and responsiveness of care). RESULTS: English-speaking Asian/Pacific Islander patients and Chinese-speaking patients and those in worse health reported significantly worse adjusted experiences with all three domains of interpersonal care, whereas white, black, and Hispanic patients reported generally similar experiences with interpersonal care. The overall quality of cancer care was rated as excellent by 44.4% of patients with lung cancer and 53.0% of patients with colorectal cancer, and these ratings were most strongly correlated with positive experiences with coordination and responsiveness of care (Spearman rank coefficients of 0.49 and 0.42 for lung and colorectal cancer, respectively). After multivariate adjustment, excellent ratings were less common for each cancer among black patients, English-speaking Asian/Pacific Islander patients, Chinese-speaking patients, and patients reporting worse health status (all P CONCLUSION: Patients' reports and ratings of care differed significantly by race, language, and health status. Efforts to improve patients' experiences with cancer care should focus on problems affecting Asian and Pacific Islander patients and those in worse health.

Common genetic variants in peroxisome proliferator-activated receptor-gamma (PPARG) and type 2 diabetes risk among Women's Health Initiative postmenopausal womenCONTEXT: Peroxisome proliferator-activated receptor-gamma (PPARG) plays a pivotal role in adipogenesis and glucose homeostasis. OBJECTIVE: We investigated whether PPARG gene variants were associated with type 2 diabetes (T2D) risk in the multiethnic Women's Health Initiative (WHI). RESEARCH DESIGN AND METHODS: We assessed PPARG single-nucleotide polymorphisms (SNPs) in a case-control study nested in the prospective WHI observational study (WHI-OS) (1543 T2D cases and 2170 matched controls). After identifying 24 tagSNPs, we used multivariable logistic regression models and haplotype-based analyses to estimate these tagSNP-T2D associations. Single-SNP analyses were also conducted in another study of 5642 African American and Hispanic American women in the WHI SNP Health Association Resource (WHI-SHARe). RESULTS: We found a borderline significant association between the Pro12Ala (rs1801282) variant and T2D risk in WHI-OS [odds ratio (OR) 0.51, 95% confidence interval (CI) 0.31-0.83, P = .01, combined group, additive model; P = .04, Hispanic American] and WHI-SHARe (OR 0.25, 95% CI 0.08-0.77, P = .02, Hispanic American) participants. In promoter region, rs6809631, rs9817428, rs10510411, rs12629293, and rs12636454 were also associated with T2D risk (range ORs 0.68-0.78, 95% CIs 0.52-0.91 to 0.60-1.00, P CONCLUSIONS: The association between PPARG Pro12Ala SNP and increased T2D susceptibility was confirmed, with Pro12 as risk allele. Additional significant loci included 5 PPARG promoter variants.

Is there a menopausal syndrome? Menopausal status and symptoms across racial/ethnic groupsIn recent years, research on menopausal symptomalogy has focused on identifying symptom groupings experienced by women as they progress from premenopausal to postmenopausal status. However, most of these studies have been conducted among Caucasian women from western cultures. This leaves open the question of whether the findings from these studies can be extended to women of other racial/ethnic groups or cultures. Furthermore, many of the previous studies have been conducted on relatively small samples. This paper addresses the diversity of the menopause experience by comparing symptom reporting in a large cross-sectional survey of women aged 40-55 years among racial/ethnic groups of women in the United States (Caucasian, African-American, Chinese, Japanese, and Hispanic). Evaluation of the extent to which symptoms group together and consistently relate to menopausal status across these five samples provides evidence for or against a universal menopausal syndrome. The specific research questions addressed in this paper are: (1) How does the factor structure of symptoms among mid-aged women compare across racial/ethnic groups? (2) Is symptom reporting related to race/ethnicity or menopausal status? and (3) Does the relation between menopausal status and symptoms vary across racial/ethnic groups? Analyses are based on 14,906 women who participated in the multi-ethnic, multi-race, multi-site study of mid-aged women called the Study of Women's Health Across the Nation (SWAN). Study participants completed a 15-min telephone or in-person interview that contained questions on a variety of health-related topics. Items of interest for these analyses include symptoms, menstrual history (to assess menopausal status), health status, and sociodemographics. Factor analysis results showed that across all five racial/ethnic groups, two consistent factors emerged; one consisting of clearly menopausal symptoms -- hot flashes and night sweats -- and the other consisting of psychological and psychosomatic symptoms. Results of regression analyses showed racial/ethnic differences in symptom reporting, as well as differences by menopausal status. Controlling for age, education, health, and economic strain, Caucasian women reported significantly more psychosomatic symptoms than other racial/ethnic groups. African-American women reported significantly more vasomotor symptoms. Perimenopausal women, hormone users, and women who had a surgical menopause reported significantly more vasomotor symptoms. All of these groups, plus postmenopausal women, reported significantly more vasomotor symptoms than premenopausal women. The pattern of results argues against a universal menopausal syndrome consisting of a variety of vasomotor and psychological symptoms.
