Cardiovascular Burden of the V142I Transthyretin Variant.

Importance: Individual cohort studies concur that the amyloidogenic V142I variant of the transthyretin (TTR) gene, present in 3% to 4% of US Black individuals, increases heart failure (HF) and mortality risk. Precisely defining carrier risk across relevant clinical outcomes and estimating population burden of disease are important given established and emerging targeted treatments. Objectives: To better define the natural history of disease in carriers across mid to late life, assess variant modifiers, and estimate cardiovascular burden to the US population. Design, Setting, and Participants: A total of 23 338 self-reported Black participants initially free from HF were included in 4 large observational studies across the US (mean [SD], 15.5 [8.2] years of follow-up). Data analysis was performed between May 2023 and February 2024. Exposure: V142I carrier status (n = 754, 3.2%). Main Outcomes and Measures: Hospitalizations for HF (including subtypes of reduced and preserved ejection fraction) and all-cause mortality. Outcomes were analyzed by generating 10-year hazard ratios for each age between 50 and 90 years. Using actuarial methods, mean survival by carrier status was estimated and applied to the 2022 US population using US Census data. Results: Among the 23 338 participants, the mean (SD) age at baseline was 62 (9) years and 76.7% were women. Ten-year carrier risk increased for HF hospitalization by age 63 years, predominantly driven by HF with reduced ejection fraction, and 10-year all-cause mortality risk increased by age 72 years. Only age (but not sex or other select variables) modified risk with the variant, with estimated reductions in longevity ranging from 1.9 years (95% CI, 0.6-3.1) at age 50 to 2.8 years (95% CI, 2.0-3.6) at age 81. Based on these data, 435 851 estimated US Black carriers between ages 50 and 95 years are projected to cumulatively lose 957 505 years of life (95% CI, 534 475-1 380 535) due to the variant. Conclusions and Relevance: Among self-reported Black individuals, male and female V142I carriers faced similar and substantial risk for HF hospitalization, predominantly with reduced ejection fraction, and death, with steep age-dependent penetrance. Delineating the individual contributions of, and complex interplay among, the V142I variant, ancestry, the social construct of race, and biological or social determinants of health to cardiovascular disease merits further investigation.

Beyond checkboxes: A qualitative assessment of physicians' experiences providing care in a patient-centred medical home.

RATIONALE, AIMS, AND OBJECTIVES: The patient-centred medical home (PCMH) is an innovative approach to health care reform. Despite a well-established process for recognizing PCMH practices, fidelity to, and/or adaptation of, the PCMH model can limit health care and population health improvements. This study explored the connection between fidelity/adaptation to the PCMH model with implementation successes and challenges through the experiences of family and internal medicine PCMH physicians. METHODS: Interviews were conducted at two academic PCMH clinics with faculty and resident physicians. Data were transcribed and coded on the basis of an a priori code list. Together, the authors reviewed text and furthered the analysis process to reach final interpretation of the data. RESULTS: Ten faculty and nine resident physicians from the Family Care Centre (FCC; n = 11) and the Internal Medicine Clinic (IMC; n = 8) were interviewed. Both FCC and IMC physicians spoke positively about their clinic's adherence to the PCMH model of enhanced access to care, coordinated/integrated care, and improvements in quality and safety through data collection and documentation. However, physicians highlighted inadequate staffing and clinic hours. FCC physicians also discussed the challenge of providing high-quality care amidst differences in coverage between payers. CONCLUSION: There remains significant variability in PCMH characteristics across the United States and Canada. This qualitative analysis uncovered factors contributing to fidelity/adaptation to the PCMH model in two academic PCMH clinics. For the PCMH to achieve the Triple Aim promise of improved patient health and experience at a reduced cost, policy must support fidelity to core elements of the PCMH.

Early life disadvantage and adult adiposity: tests of sensitive periods during childhood and behavioural mediation in adulthood.

BACKGROUND: Early exposure to socioeconomic disadvantage is associated with obesity. Here we investigated how early, and conducted mediation analyses to identify behavioural factors in adulthood that could explain why. METHODS: Among 931 participants in the New England Family Study, we investigated the associations of family socioeconomic disadvantage measured before birth and at age 7 years with the following measures of adiposity in mid-adulthood (mean age = 44.4 years): body mass index (BMI), waist circumference and, among 400 participants, body composition from dual-energy X-ray absorption scans. RESULTS: In linear regressions adjusting for age, sex, race and childhood BMI Z-score, participants in the highest tertile of socioeconomic disadvantage at birth had 2.6 additional BMI units in adulthood [95% confidence interval (CI) = 1.26, 3.96], 5.62 cm waist circumference (95% CI = 2.69, 8.55), 0.73 kg of android fat mass (95% CI = 0.25, 1.21), and 7.65 higher Fat Mass Index (95% CI = 2.22, 13.09). Conditional on disadvantage at birth, socioeconomic disadvantage at age 7 years was not associated with adult adiposity. In mediation analyses, 10-20% of these associations were explained by educational attainment and 5-10% were explained by depressive symptoms. CONCLUSIONS: Infancy may be a sensitive period for exposure to socioeconomic disadvantage, as exposure in the earliest years of life confers a larger risk for overall and central adiposity in mid-adulthood than exposure during childhood. Intervention on these two adult risk factors for adiposity would, if all model assumptions were satisfied, only remediate up to one-fifth of the excess adult adiposity among individuals born into socioeconomically disadvantaged households.

Subsidies for Oral Chemotherapy and Use of Immunomodulatory Drugs Among Medicare Beneficiaries With Myeloma.

Purpose The low-income subsidy (LIS) substantially lowers out-of-pocket costs for qualifying Medicare Part D beneficiaries who receive orally administered chemotherapy. We examined the association of LIS with the use of novel oral immunomodulatory drugs (IMiDs; lenalidomide and thalidomide) among beneficiaries with myeloma, who can receive either orally administered or parenteral (bortezomib-based) therapy. Methods Using SEER-Medicare data, we identified Part D beneficiaries diagnosed with myeloma in 2007 to 2011. In multivariable models adjusted for sociodemographic and clinical characteristics, we analyzed associations between the LIS and use of IMiD-based therapy, delays between IMiD refills, and select health outcomes during the first year of therapy. Results Among 3,038 beneficiaries, 41% received first-line IMiDs. Median out-of-pocket cost for the first IMiD prescription was $3,178 for LIS nonrecipients and $3 for LIS recipients, whereas the respective median costs for the first year of therapy were $5,623 and $6, respectively. Receipt of the LIS was associated with a 32% higher (95% CI, 16% to 47%) probability of receiving IMiDs among beneficiaries age 75 to 84 years and a significantly lower risk of delays between refills in all age groups (adjusted relative risk, 0.54; 95% CI, 0.32 to 0.92). Duration of therapy did not significantly differ between LIS recipients and nonrecipients (median, 7.6 months). Patients treated with IMiDs had significantly fewer emergency department visits and hospitalizations compared with patients receiving bortezomib (without IMiDs), but 1-year overall survival and cumulative Medicare costs were similar. Conclusion Medicare beneficiaries with myeloma who do not receive LISs face a substantial financial barrier to accessing orally administered anticancer therapy, warranting urgent attention from policymakers. Limiting out-of-pocket costs for expensive anticancer drugs like the IMiDs may improve access to oral therapy for patients with myeloma.

Venous thromboembolism incidence, recurrence, and mortality based on Women's Health Initiative data and Medicare claims.

INTRODUCTION: Our objective was to compare Medicare claims to physician review and adjudication of medical records for identifying venous thromboembolism (VTE), and to assess VTE incidence, recurrence, and mortality in a large national cohort of post-menopausal women followed up to 19years. MATERIALS AND METHODS: We used detailed clinical data from the Women's Health Initiative (WHI) linked to Medicare claims. Agreement between data sources was evaluated among 16,003 women during 1993-2010. A claims-based definition was selected to analyze VTE occurrence and impact among 71,267 women during 1993-2012. RESULTS: Our VTE definition had 83% sensitivity. Positive predictive value was 69% when all records were included, and 94% after limiting Medicare records to those with a WHI hospitalization adjudicated. Annualized VTE incidence was 4.06/1000person-years (PY), recurrence was 5.30/100PY, and both rates varied by race/ethnicity. Post-VTE mortality within 1year was 22.49% from all causes, including 1.01% from pulmonary embolism, 10.40% from cancer, and 11.08% from other causes. Cancer-related VTE compared to non-cancer VTE had significantly (p<0.001) higher recurrence (9.86/100PY vs. 4.43/100PY) and mortality from all causes (45.89% vs. 12.28%), but not from pulmonary embolism (0.40% vs. 1.27%). CONCLUSIONS: Medicare claims compared reasonably well to physician adjudication. The combined data sources provided new insights about VTE burden and prognosis in older women.

Epigenetic Mediators Between Childhood Socioeconomic Disadvantage and Mid-Life Body Mass Index: The New England Family Study.

OBJECTIVE: Childhood socioeconomic disadvantage is associated with adulthood obesity risk; however, epigenetic mechanisms are poorly understood. This work's objective was to evaluate whether associations of childhood socioeconomic disadvantage with adulthood body mass index (BMI) are mediated by DNA methylation. METHODS: Participants were 141 men and women from the New England Family Study, prospectively followed prenatally through a mean age of 47 years. Epigenomewide DNA methylation was evaluated in peripheral blood and adipose tissue obtained at adulthood, using the Infinium HumanMethylation450K BeadChip. Childhood socioeconomic status (SES) at age 7 years was assessed directly from parents' reports. Offspring adiposity was directly assessed using BMI at a mean age of 47 years. Associations of SES, DNA methylation, and BMI were estimated using least square estimators. Statistical mediation analyses were performed using joint significance test and bootstrapping. RESULTS: Of CpG sites significant at the 25% false discovery rate level in epigenomewide methylation BMI analyses, 91 sites in men and 71 sites in women were additionally significant for SES-methylation associations (p < .001) in adipose tissue. Many involved genes biologically relevant for development of obesity, including fatty acid synthase, transmembrane protein 88, signal transducer and activator of transcription 3, and neuritin 1. There was no evidence of epigenetic mediation in peripheral blood leukocytes. CONCLUSIONS: DNA methylation at specific genes may be mediators of associations between childhood socioeconomic disadvantage and mid-life BMI in adipose tissue. Findings motivate continued efforts to study if and how childhood socioeconomic disadvantage is biologically embedded at the level of the epigenome in regions etiologically relevant for adiposity.

Patterns and predictors of medication adherence to lipid-lowering therapy in children aged 8 to 20 years.

BACKGROUND: The American Academy of Pediatrics recommends lipid-lowering therapy (LLT) for children at high risk of cardiovascular disease. However, the use of LLT in children is rare, and rates of nonadherence are unknown. OBJECTIVE: To identify patterns of use and predictors of nonadherence to LLT in children aged 8 to 20 years and the subgroup with dyslipidemia. METHODS: Commercially insured patients with a new dispensing for an LLT were included. Nonadherence was defined as a gap of >90 days between the last dispensing plus the medication days supply and the next dispensing or censoring. Descriptive statistics characterize the patterns of LLT adherence and class-specific drug switching. Kaplan-Meier curves and multivariable Cox proportional hazard models identified time to, and predictors of, nonadherence for the cohort and the dyslipidemia subgroup. RESULTS: Of the 8710 patients meeting inclusion criteria, 87% were nonadherent. Statins were the most common index prescription, and patients with an index statin dispensing were more likely to have multiple comorbidities and other prescription drug use. In multivariable analyses, nonadherence was inversely associated with dyslipidemia (hazard ratio [HR] = 0.61, 95% confidence interval [CI] = 0.57-0.65), chronic kidney disease (HR = 0.69, 95% CI = 0.54-0.88), higher outpatient (HR = 0.87, 95% CI = 0.77-0.98), and inpatient (HR = 0.83, 95% CI = 0.70-0.97) use. When limited to patients with dyslipidemia, nonadherence was related to age (HR = 1.21, 95% CI = 1.07-1.38) and obesity (HR = 1.23, 95% CI = 1.02-1.49). CONCLUSIONS: Despite recommendations to begin continuous treatment early for high-risk children, nonadherence to LLT is frequent in this population, with modestly higher adherence in children with dyslipidemia.

Symptom assessment in knee osteoarthritis needs to account for physical activity level.

OBJECTIVE: Pain is not always correlated with severity of radiographic osteoarthritis (OA), possibly because people modify activities to manage symptoms. Measures of symptoms that consider pain in the context of activity level may therefore provide greater discrimination than a measure of pain alone. We undertook this study to compare discrimination provided by a measure of pain alone with that provided by combined measures of pain in the context of physical activity across radiographic OA severity levels. METHODS: This was a cross-sectional study nested within the Osteoarthritis Initiative (OAI). The population was drawn from 2,127 persons enrolled in an OAI accelerometer monitoring substudy, including those with and those without knee OA. Two composite pain and activity knee symptom (PAKS) scores were calculated as the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain score (plus 1) divided by a physical activity measure (step count for the first PAKS score [PAKS1 score] and activity count for the second PAKS score [PAKS2 score]). Symptom score discrimination across Kellgren/Lawrence (K/L) grades was evaluated using histograms and quantile regression. RESULTS: A total of 1,806 participants (55.5% of whom were women) were included (mean ± SD age 65.1 ± 9.1 years, mean ± SD body mass index 28.4 ± 4.8 kg/m(2) ). The WOMAC pain score, but not the PAKS scores, exhibited a floor effect. The adjusted median WOMAC pain scores by K/L grades 0-4 were 0, 0, 0, 1, and 3, respectively. The adjusted median PAKS1 scores were 24.9, 26.0, 32.4, 46.1, and 97.9, respectively, and the adjusted median PAKS2 scores were 7.2, 7.2, 9.2, 12.9, and 23.8, respectively. The PAKS scores had more statistically significant comparisons between K/L grades than did the WOMAC pain score. CONCLUSION: Symptom assessments incorporating pain and physical activity did not exhibit a floor effect and were better able to discriminate radiographic severity than an assessment of pain alone, particularly in milder disease. Pain in the context of physical activity level should be used to assess knee OA symptoms.

Relationship of meeting physical activity guidelines with quality-adjusted life-years.

OBJECTIVE: The quality-adjusted life-year (QALY) is a standard outcome measure used in cost-effectiveness analyses. This study investigates whether attainment of federal physical activity guidelines is associated with higher QALY estimates among adults with or at an increased risk for knee osteoarthritis. METHODS: This is a prospective study of 1794 Osteoarthritis Initiative participants. Physical activity was measured using accelerometers at baseline. Participants were classified as (1) Meeting Guidelines [≥150min of moderate-to-vigorous (MV) activity per week acquired in sessions ≥10min], (2) Insufficiently Active (≥1 MV session[s]/week but below the guideline), or (3) Inactive (zero MV sessions/week). A health-related utility score was derived from participant responses to the 12-item Short-Form Health Survey at baseline and 2 years later. The QALY was calculated as the area under utility curve over 2 years. The relationship of physical activity level to median QALY adjusted for socioeconomic and health factors was estimated using quantile regression. RESULTS: Relative to the Inactive group, median QALYs over 2 years were significantly higher for the Meeting Guidelines (0.112, 95% CI: 0.067-0.157) and Insufficiently Active (0.058, 95% CI: 0.028-0.088) groups, controlling for socioeconomic and health factors. CONCLUSION: We found a significant graded relationship between greater physical activity level and higher QALYs. Using the more conservative estimate of 0.058, if an intervention could move someone out of the Inactive group and costs <$2900 over 2 years, it would be considered cost effective. Our analysis supports interventions to promote physical activity even if recommended levels are not fully attained.

Cardiac risk factors: environmental, sociodemographic, and behavioral cardiovascular risk factors.

Several environmental exposures are associated with increased risk of coronary heart disease (CHD). Exposure to secondhand smoke may increase the risk by as much as 25% to 30%. Exposure to third hand smoke, residual components of tobacco smoke that remain in the environment after a cigarette is extinguished, also appears to increase risk. These residual components can remain in rooms and automobiles for up to 30 years and enter the body through the skin or via inhalation or ingestion. Exposure to particulate matter air pollution from automobile emissions, power plants, and other sources is yet another environmental risk factor for CHD, resulting in tens of thousands of deaths annually in the United States. Exposure to other environmental toxins, particularly bisphenol A and phthalates, also has been linked to CHD. There are sociodemographic risks for CHD, with numerous studies showing that lower socioeconomic status is associated with higher risk. Behavioral risk factors include poor diet, such as frequent consumption of fast food and processed meals; sleep disturbance; and psychological stress, particularly related to marital or work issues. Finally, although high alcohol consumption is associated with increased CHD risk, moderate alcohol consumption (ie, less than 1 to 2 drinks/day), particularly of wine and possibly beer, appears to reduce the risk.

Tailored weight loss intervention in obese adults within primary care practice: rationale, design, and methods of Choose to Lose.

Although there are efficacious weight loss interventions that can improve health and delay onset of diabetes and hypertension, these interventions have not been translated into clinical practice. The primary objective of this study is to evaluate the effectiveness and cost effectiveness of a tailored lifestyle intervention in primary care patients. Patients were recruited by their primary care physicians and eligible participants were randomized to an enhanced intervention or standard intervention. All participants met with a lifestyle counselor to set calorie and physical activity goals and to discuss behavioral strategies at baseline, 6 and 12 months. During the first year, enhanced intervention participants receive monthly counseling phone calls to assist in attaining and maintaining their goals. Enhanced intervention participants also receive weekly mailings consisting of tailored and non-tailored print materials and videos focusing on weight loss, physical activity promotion and healthy eating. The second year focuses on maintenance with enhanced intervention participants receiving tailored and non-tailored print materials and videos regularly throughout the year. Standard intervention participants receive five informational handouts on weight loss across the two years. This enhanced intervention that consists of multiple modalities of print, telephone, and video with limited face-to-face counseling holds promise for being effective for encouraging weight loss, increasing physical activity and healthy eating, and also for being cost effective and generalizable for wide clinical use. This study will fill an important gap in our knowledge regarding the translation and dissemination of research from efficacy studies to best practices in clinical settings.

Relationship of meeting physical activity guidelines with health-related utility.

OBJECTIVE: Health-related utility measures overall health status and quality of life and is commonly incorporated into cost-effectiveness analyses. This study investigates whether attainment of federal physical activity guidelines translates into better health-related utility in adults with or at risk for knee osteoarthritis (OA). METHODS: Cross-sectional data from 1,908 adults with or at risk for knee OA participating in the accelerometer ancillary study of the Osteoarthritis Initiative were assessed. Physical activity was measured using 7 days of accelerometer monitoring and was classified as 1) meeting guidelines (≥150 bouted moderate-to-vigorous [MV] minutes per week); 2) insufficiently active (≥1 MV bout[s] per week but below guidelines); or 3) inactive (zero MV bouts per week). A Short Form 6D health-related utility score was derived from patient-reported health status. Relationship of physical activity levels to median health-related utility adjusted for socioeconomic and health factors was tested using quantile regression. RESULTS: Only 13% of participants met physical activity guidelines, and 45% were inactive. Relative to the inactive group, median health-related utility scores were significantly greater for the meeting guidelines group (0.063; 95% confidence interval [95% CI] 0.055, 0.071) and the insufficiently active group (0.059; 95% CI 0.054, 0.064). These differences showed a statistically significant linear trend and strong cross-sectional relationship with physical activity level even after adjusting for socioeconomic and health factors. CONCLUSION: We found a significant positive relationship between physical activity level and health-related utility. Interventions that encourage adults, including persons with knee OA, to increase physical activity even if recommended levels are not attained may improve their quality of life.

Social support and physical activity as moderators of life stress in predicting baseline depression and change in depression over time in the Women's Health Initiative.

PURPOSE: To determine whether social support and/or physical activity buffer the association between stressors and increasing risk of depression symptoms at baseline and at 3-year follow-up. METHODS: This is a secondary analysis of data from the Women's Health Initiative Observational Study. 91,912 community-dwelling post-menopausal women participated in this prospective cohort study. Depression symptoms were measured at baseline and 3 years later; social support, physical activity, and stressors were measured at baseline. RESULTS: Stressors at baseline, including verbal abuse, physical abuse, caregiving, social strain, negative life events, financial stress, low income, acute pain, and a greater number of chronic medical conditions, were all associated with higher levels of depression symptoms at baseline and new onset elevated symptoms at 3-year follow-up. Social support and physical activity were associated with lower levels of depressive symptoms. Contrary to expectation, more social support at baseline strengthened the association between concurrent depression and physical abuse, social strain, caregiving, and low income. Similarly, more social support at baseline increased the association between financial stress, income, and pain on new onset depression 3 years later. Physical activity similarly moderated the effect of caregiving, income, and pain on depression symptoms at baseline. CONCLUSION: Stressors, social support, and physical activity showed predicted main effect associations with depression. Multiplicative interactions were small in magnitude and in the opposite direction of what was expected.

Recreational physical activity in postmenopausal women is stable over 8 years of follow-up.

BACKGROUND: The goals of this study were to examine 1) longitudinal trajectories of energy expenditure from recreational physical activity (PA) in postmenopausal women, 2) whether women who belong to different PA trajectories engage in different types of PA, and 3) whether baseline sociodemographic, health, psychosocial, and lifestyle characteristics predict membership in PA trajectories. METHODS: Women from the Women's Health Initiative Observational Study with baseline PA data (n = 92,629) were included. Physical activity, measured via self-report 6 times over 8 years, was converted to MET hr/wk for analysis. Latent growth curve mixture models and latent profile models were used to analyze longitudinal PA trajectories and cross-sectional PA composition, respectively. RESULTS: Three distinct, stable PA trajectories (highly, moderately, and minimally active) were identified with nearly 75% of the women classified as minimally active (≤ 8 MET-hr/wk). The majority of women who were at least moderately active engaged in a balanced combination of walking, moderate, and vigorous PA. Sociodemographic characteristics such as income, education, and past vigorous PA were predictive of PA trajectory, as were some health status indicators (eg, body mass index), but not health related quality of life. CONCLUSIONS: Self-reported PA is largely stable across nearly a decade of follow-up in postmenopausal women.

Tailored DVDs: a novel strategy for educating racially and ethnically diverse older adults about their medicines.

INTRODUCTION: The availability of comprehensive and accurate medication history information in electronic medical records and through electronic prescribing provides the opportunity to create tailored interventions based on individuals' particular medication information needs. To meet the challenges of providing medication information to low-literate English and Spanish speaking older adults, we sought to create individualized, culturally and linguistically inclusive medication education materials for older adults from diverse backgrounds. METHODS: We used a mixed-method design including a systematic review, analysis of existing data, a telephone survey (n=326), and exploratory focus groups stratified by race/ethnicity and language spoken (11 focus groups; n=106) to identify what information about medications older adults need, want to learn, and in what format. We evaluated reactions to three DVDs at low-income senior community centers (2 focus groups; n=16). RESULTS: Exploratory focus groups provided insights on areas for improvement in patient-provider communication, and suggested use of vignettes and testimonials. Upon viewing, participants could relate to the testimonials in which actors portrayed people who have problems with their medications and were interested in the medication advice presented, especially when it was presented by a healthcare professional. DISCUSSION: Tailored medication education materials in English and Spanish DVD and print material format are suitable for low-literate audiences, acceptable to older adults, and feasible to implement using health IT. Virtually all households in the United States have a television, with most having a DVD player. DVD segments can be used in Internet links, physician office-based television, and consumer health IT applications.

Evaluation and comparison of food records, recalls, and frequencies for energy and protein assessment by using recovery biomarkers.

The food frequency questionnaire approach to dietary assessment is ubiquitous in nutritional epidemiology research. Food records and recalls provide approaches that may also be adaptable for use in large epidemiologic cohorts, if warranted by better measurement properties. The authors collected (2007-2009) a 4-day food record, three 24-hour dietary recalls, and a food frequency questionnaire from 450 postmenopausal women in the Women's Health Initiative prospective cohort study (enrollment, 1994-1998), along with biomarkers of energy and protein consumption. Through comparison with biomarkers, the food record is shown to provide a stronger estimate of energy and protein than does the food frequency questionnaire, with 24-hour recalls mostly intermediate. Differences were smaller and nonsignificant for protein density. Food frequencies, records, and recalls were, respectively, able to "explain" 3.8%, 7.8%, and 2.8% of biomarker variation for energy; 8.4%, 22.6%, and 16.2% of biomarker variation for protein; and 6.5%, 11.0%, and 7.0% of biomarker variation for protein density. However, calibration equations that include body mass index, age, and ethnicity substantially improve these numbers to 41.7%, 44.7%, and 42.1% for energy; 20.3%, 32.7%, and 28.4% for protein; and 8.7%, 14.4%, and 10.4% for protein density. Calibration equations using any of the assessment procedures may yield suitable consumption estimates for epidemiologic study purposes.

Antipsychotic use and the risk of diabetes in nursing home residents with dementia.

BACKGROUND: Growing evidence suggests an association between antipsychotic use and diabetes onset in schizophrenia, but little is known about this association among patients with dementia. OBJECTIVE: The aim of this study was to quantify the association between antipsychotic use and the risk of diabetes onset among nursing home residents with dementia. METHODS: We conducted a nested case-control study in 29,203 long-stay Medicaid-eligible residents living in nursing homes in California, Florida, Illinois, New York, and Ohio between January 2001 and December 2002 who were at least 65 years old with a dementia diagnosis and no record of diabetes within 90 days of nursing home admission. We identified 762 incident cases of diabetes and randomly selected up to 5 controls, matched on nursing home and quarter of minimum data set (MDS) assessment (N = 2646). Cases of incident diabetes were identified from MDS assessments and Medicaid claims, medication use was ascertained from Medicaid pharmacy files, and resident characteristics were obtained from MDS assessments. RESULTS: Relative to non-users of antipsychotics, use of atypical antipsychotics was not associated with diabetes onset (adjusted odds ratio [AOR] = 1.03; 95% CI, 0.84-1.27) and risk of diabetes did not increase with length of time on treatment. Conventional antipsychotic treatment was associated with diabetes onset, particularly when treatment duration was <30 days (AOR = 2.70; 95% CI, 1.57-4.65). CONCLUSIONS: Among nursing home residents with dementia, conventional antipsychotic therapy, particularly short-term therapy, increased their risk of developing diabetes. Atypical antipsychotic use was not associated with an increased risk of diabetes onset.

Renewing primary care: lessons learned from the Spanish health care system.

From 1978 on, Spain rapidly expanded and strengthened its primary health care system, offering a lesson in how to improve health outcomes in a cost-effective manner. The nation moved to a tax-based system of universal access for the entire population and, at the local level, instituted primary care teams coordinating prevention, health promotion, treatment, and community care. Gains included increases in life expectancy and reductions in infant mortality, with outcomes superior to those in the United States. In 2007 Spain spent $2,671 per person, or 8.5 percent of its gross domestic product on health care, versus 16 percent in the United States. Despite concerns familiar to Americans--about future shortages of primary care physicians and relatively low status and pay for these physicians--the principles underlying the Spanish reforms offer lessons for the United States.

Correlates of sexual satisfaction among sexually active postmenopausal women in the Women's Health Initiative-Observational Study.

BACKGROUND: Satisfaction with sexual activity is important for health-related quality of life, but little is known about the sexual health of postmenopausal women. OBJECTIVE: Describe factors associated with sexual satisfaction among sexually active postmenopausal women. DESIGN: Cross-sectional analysis. PARTICIPANTS: All members of the Women's Health Initiative-Observational Study (WHI-OS), ages 50-79, excluding women who did not respond to the sexual satisfaction question or reported no partnered sexual activity in the past year (N = 46,525). PRIMARY OUTCOME: dichotomous response to the question, "How satisfied are you with your sexual activity (satisfied versus unsatisfied)?" Covariates included sociodemographic factors, measures of physical and mental health, and gynecological variables, medications, and health behaviors related to female sexual health. RESULTS: Of the cohort, 52% reported sexual activity with a partner in the past year, and 96% of these answered the sexual satisfaction question. Nonmodifiable factors associated with sexual dissatisfaction included age, identification with certain racial or ethnic groups, marital status, parity, and smoking history. Potentially modifiable factors included lower mental health status and use of SSRIs. The final model yielded a c-statistic of 0.613, reflecting only a modest ability to discriminate between the sexually satisfied and dissatisfied. CONCLUSIONS: Among postmenopausal women, the variables selected for examination yielded modest ability to discriminate between sexually satisfied and dissatisfied participants. Further study is necessary to better describe the cofactors associated with sexual satisfaction in postmenopausal women.
