Risk Factors for Post-Discharge Adverse Outcomes Following Hospitalization Among Older Adults Diagnosed With Elder Mistreatment

Using 100% Medicare data files, this study explored whether primary elder mistreatment (EM) diagnosis, EM type, and facility type were associated with 3-year mortality and 1-year unplanned hospital readmission among older patients diagnosed with EM with hospital discharge from 10/01/2015 through 12/31/2018 (n = 11,023). We also examined outcome differences between older patients diagnosed with EM and matched non-EM patient controls. Neglect by others was the most common EM diagnosis. Three-year mortality was 56.7% and one-year readmission rate was 53.8%. Compared to matched non-EM patient controls, older EM patients were at an increased risk of mortality and readmission. Among patients diagnosed with EM, patients with a secondary (vs. primary) diagnosis and those discharged from a skilled nursing facility (vs. acute hospital) were at an increased risk for both mortality and readmission. Compared to other EM types, patients diagnosed with neglect by others had a greater risk for mortality following discharge.

Caregiving and all-cause mortality in postmenopausal women: Findings from the Women's Health Initiative

BACKGROUND

Caregiving is commonly undertaken by older women. Research is mixed, however, about the impact of prolonged caregiving on their health, well-being, and mortality risk. Using a prospective study design, we examined the association of caregiving with mortality in a cohort of older women.

METHODS

Participants were 158,987 postmenopausal women aged 50-79 years at enrollment into the Women's Health Initiative (WHI) who provided information on current caregiving status and caregiving frequency at baseline (1993-1998) and follow-up (2004-2005). Mortality was ascertained from baseline through March of 2019. Cox regression with caregiving status defined as a time-varying exposure was used to estimate hazard ratios (HR) and 95% confidence intervals (CI) for mortality, adjusting for sociodemographic factors, smoking, and history of diabetes, hypertension, cardiovascular disease (CVD), and cancer. Stratified analyses explored whether age, race-ethnicity, depressive symptoms, frequency of caregiving, optimism, and living status modified the association between caregiver status and mortality.

RESULTS

At baseline, 40.7% of women (mean age 63.3 years) self-identified as caregivers. During a mean 17.5-year follow-up, all-cause mortality (50,526 deaths) was 9% lower (multivariable-adjusted HR = 0.91, 95% CI: 0.89-0.93) in caregivers compared to non-caregivers. The inverse association between caregiving and all-cause mortality did not differ according to caregiving frequency or when stratified by age, race-ethnicity, depressive symptoms, optimism, or living status (interaction p > 0.05, all). Caregiving was inversely associated with CVD and cancer mortality.

CONCLUSION

Among postmenopausal women residing across the United States, caregiving was associated with lower mortality. Studies detailing the type and amount of caregiving are needed to further determine its impact on older women.

Allostatic load and risk of invasive breast cancer among postmenopausal women in the U.S

OBJECTIVE

Allostatic load can reflect the body's response to chronic stress. However, little is known about the association between allostatic load and risk of breast cancer in postmenopausal women. This study used a large prospective cohort in the United States to examine the relationship between allostatic load and invasive breast cancer risk, and to evaluate the relationship by racial and ethnic identity and breast cancer subtypes.

METHODS

Among 161,808 postmenopausal participants in Women's Health Initiative, eligible were a subsample of 27,393 postmenopausal women aged 50-79 years old, who enrolled from 1993 to 1998, had serum test biomarkers, and were followed for breast cancer incidence through February 2022. Allostatic load at enrollment was computed based on eight biomarkers from lab serum tests and a questionnaire about participants' prescription drug use. The associations between allostatic scores and risk of breast cancer (overall and by subtypes) were assessed using Cox proportional hazards models. The race and ethnic differences were examined.

RESULTS

Over a median follow-up time of 17.24 years, 1722 invasive breast cancer cases were identified. High allostatic load was associated with an increased risk of breast cancer (HR = 1.36, 95%CI: 1.20, 1.54 for third tertile vs first tertile, Ptrend < 0.0001). Similar trends were found in White women and non-Hispanic women. Higher allostatic load was associated with hormone receptor-positive and HER2/Neu-negative breast cancer (HR = 1.54, 95%CI: 1.30, 1.80 for third tertile vs first tertile, Ptrend < 0.0001).

CONCLUSION

In this study, we found that higher allostatic load was significantly associated with an increased risk of breast cancer in postmenopausal women.

Racial and Ethnic Differences in Self-Reported COVID-19 Exposure Risks, Concerns, and Behaviors Among Diverse Participants in the Women's Health Initiative Study

BACKGROUND

Racial and ethnic disparities in coronavirus disease 2019 (COVID-19) risk are well-documented; however, few studies in older adults have examined multiple factors related to COVID-19 exposure, concerns, and behaviors or conducted race- and ethnicity-stratified analyses. The Women's Health Initiative (WHI) provides a unique opportunity to address those gaps.

METHODS

We conducted a secondary analysis of WHI data from a supplemental survey of 48 492 older adults (mean age 84 years). In multivariable-adjusted modified Poisson regression analyses, we examined predisposing factors and COVID-19 exposure risk, concerns, and behaviors. We hypothesized that women from minoritized racial or ethnic groups, compared to non-Hispanic White women, would be more likely to report: exposure to COVID-19, a family or friend dying from COVID-19, difficulty getting routine medical care or deciding to forego care to avoid COVID-19 exposure, and having concerns about the COVID-19 pandemic.

RESULTS

Asian women and non-Hispanic Black/African American women had a higher risk of being somewhat/very concerned about risk of getting COVID-19 compared to non-Hispanic White women and each was significantly more likely than non-Hispanic White women to report forgoing medical care to avoid COVID-19 exposure. However, Asian women were 35% less likely than non-Hispanic White women to report difficulty getting routine medical care since March 2020 (adjusted relative risk 0.65; 95% confidence interval 0.57, 0.75).

CONCLUSIONS

We documented COVID-related racial and ethnic disparities in COVID-19 exposure risk, concerns, and care-related behaviors that disfavored minoritized racial and ethnic groups, particularly non-Hispanic Black/African American women.

Menopausal hormone therapy and change in physical activity in the Women's Health Initiative hormone therapy clinical trials

OBJECTIVE

The menopausal transition results in a progressive decrease in circulating estrogen levels. Experimental evidence in rodents has indicated that estrogen depletion leads to a reduction of energy expenditure and physical activity. It is unclear whether treatment with estrogen therapy increases physical activity level in postmenopausal women.

METHODS

A total of 27,327 postmenopausal women aged 50-79 years enrolled in the Women's Health Initiative randomized double-blind trials of menopausal hormone therapy. Self-reported leisure-time physical activity at baseline, and years 1, 3, and 6 was quantified as metabolic equivalents (MET)-h/wk. In each trial, comparison between intervention and placebo groups of changes in physical activity levels from baseline to follow-up assessment was examined using linear regression models.

RESULTS

In the CEE-alone trial, the increase in MET-h/wk was greater in the placebo group compared with the intervention group at years 3 ( P = 0.002) and 6 ( P < 0.001). Similar results were observed when analyses were restricted to women who maintained an adherence rate ≥80% during the trial or who were physically active at baseline. In the CEE + MPA trial, the primary analyses did not show significant differences between groups, but the increase of MET-h/wk was greater in the placebo group compared with the intervention group at year 3 ( P = 0.004) among women with an adherence rate ≥80%.

CONCLUSIONS

The results from this clinical trial do not support the hypothesis that estrogen treatment increases physical activity among postmenopausal women.

Continuity of care among postmenopausal women with cardiometabolic diseases in the United States early during the COVID-19 pandemic: Findings from the Women's Health Initiative

BACKGROUND

In response to the COVID-19 pandemic, public health measures, including stay-at-home orders, were widely instituted in the United States (US) by March 2020. However, few studies have evaluated the impact of these measures on continuity of care among older adults living with chronic diseases.

METHODS

Beginning in June 2020, participants of the national Women's Health Initiative (WHI) (N=64,061) were surveyed on the impact of the pandemic on various aspects of their health and well-being since March 2020, including access to care appointments, medications, and caregivers. Responses received by November 2020 (response rate=77.6%) were tabulated and stratified by prevalent chronic diseases, including hypertension, type 2 diabetes, and cardiovascular disease (CVD).

RESULTS

Among 49,695 respondents (mean age=83.6 years), 70.2% had a history of hypertension, 21.8% had diabetes, and 18.9% had CVD. Half of respondents reported being very concerned about the pandemic and 24.5% decided against seeking medical care to avoid COVID-19 exposure. A quarter reported difficulties with getting routine care and 45.5% had in-person appointments converted to telemedicine formats; many reported cancelled (27.8%) or rescheduled (37.7%) appointments. Among those taking prescribed medication (88.0%), 9.7% reported changing their method of obtaining medications. Those living with and without chronic diseases generally reported similar changes in care and medication access.

CONCLUSIONS

Early in the pandemic, many older women avoided medical care or adapted to new ways of receiving care and medications. Therefore, optimizing alternative services, like telemedicine, should be prioritized to ensure that older women continue to receive quality care during public health emergencies.

Adverse Childhood Experiences and Chronic Disease Risk in the Southern Community Cohort Study

We used the Southern Community Cohort Study of people residing in 12 states in the southeastern United States (n=38,200 participants) to examine associations between adverse childhood experiences (ACEs) and chronic disease risk. After adjustment for confounding, there were statistically significant positive associations for people reporting four or more ACEs relative to those reporting no ACEs, and this was true for all chronic diseases except hypertension. The most elevated risk was seen for depression when measured as a yes/no variable (odds ratio (OR) 2.84, 95% confidence interval (CI) 2.64-3.06) or when using the 10-item Center for Epidemiologic Student Depression (CESD) scale (OR 1.88, 95% CI 1.75-2.02). There were also statistically significant monotonic increases in risk with worsening ACE score for all chronic diseases except hypertension, cancer, and high cholesterol. The need to establish programs that build resilience during childhood is paramount for preventing chronic diseases that may result from childhood abuse, neglect, and household dysfunction.

Pharmacological approaches to the treatment of COVID-19 patients

The current COVID-19 pandemic has presented unprecedented challenges to the world community. No effective therapies or vaccines have yet been established. Upon the basis of homologies to similar coronaviruses, several potential drug targets have been identified and are the focus of both laboratory and clinical investigation. The rationale for several of these drug candidates is presented in this review. Emerging clinical data has revealed that severe COVID-19 disease is associated with heightened inflammatory responses and a procoagulant state, suggesting that patient treatment strategies must extend beyond antiviral agents. Effective approaches to the treatment of vulnerable patients with comorbidities will render COVID-19 substantially more manageable.

Adverse Childhood Experiences and Health Care Utilization in a Low-Income Population

OBJECTIVE

To determine associations of adverse childhood experiences (ACE) with adult health care utilization in an underserved, low-income population.

METHODS

Questionnaires on ACE were completed by 38,200 adults (mean age 54), two-thirds African American, recruited from community health centers (CHCs) across 12 Southeastern states. Odds ratios (ORs) and accompanying 95% confidence intervals (CIs) were computed.

RESULTS

The percentages reporting emergency room visits and doctor's office visits, with high chronic disease index scores, rose monotonically (ptrend&lt;.001) with rising ACE score. Odds ratios (CIs) for those with four or more vs. zero ACEs were 1.37 (95% CI 1.27-1.47) for 1-10 times and 1.80 (95% CI 1.29-2.52) for more than 10 times ER visits, 1.37 (95% CI 1.18-1.59) for over 10 doctor's visits, and 2.29 (95% CI 2.06-2.54) for three or more chronic diseases.

CONCLUSIONS

High ACE levels were associated with greater chronic disease burden and greater health care utilization in adulthood. Long-lasting effects from ACE on the health care of underserved populations are indicated. There is an urgent need to train health care providers, patients, and their families on ACE effects and treatments for better health care outcomes.

Elder abuse and mistreatment: results from medicare claims data

Elder abuse and mistreatment (EM) continues to be a growing problem as the US population ages. Despite the growth, detection of EM continues to lag. However, Medicare claims data and the electronic health record might provide an opportunity to encourage better detection. We evaluated Medicare claims data from 2012-2014 for beneficiaries who had a diagnostic code for EM discharged from any types of facility. We extracted records for 10,181 individuals examining demographic characteristics, residential characteristics, residential location, type of facility providing care, disease co-morbidities, and disability-related conditions. Of our sample, most were female (65.1%), white (78.8%), over 75 years of age (52.6%), and from an urban setting (85.2%). While the greatest number were discharged from acute care settings, almost one-third were hospitalized in psychiatric hospitals (34.6%). Mood disorders (27.5%) and dementia (14.2%) were the most common primary diagnoses. Hypertension (67.7%), depression (44.6%), fluid and electrolyte disorder (43.6%), and cardiac arrhythmia (28.2%) were the most common co-morbidities. In Medicare claims data, we found unique features and co-morbidities associated with EM. These findings could be used to develop a clinical algorithm predictive of older adults requiring screening for EM.

Sickle cell carriers' unmet information needs: Beyond knowing trait status

Benefits of identifying sickle cell disease (SCD) carriers include detection of at-risk couples who may be informed on reproductive choices. Studies consistently report insufficient knowledge about the genetic inheritance pattern of SCD among people with sickle cell trait (SCT). This study explored perspectives of adults with SCT on the information needed to make an informed reproductive decision and the recommendations for communicating SCT information. Five focus groups (N = 25) were conducted with African Americans with SCT ages 18-65 years old. Participants were asked about their knowledge of SCT, methods for finding information on SCT, impact of SCT on daily living, and interactions with healthcare providers. An inductive-deductive qualitative analysis was used to analyze the data for emerging themes. Four themes emerged, highlighting the unmet information needs of African American sickle cell carriers: (a) SCT and SCD Education; (b) information sources; (c) improved communication about SCT and SCD; and (d) increased screening strategies. Future studies are needed to determine effective strategies for communicating SCT information and to identify opportunities for education within community and medical settings. Identifying strategies to facilitate access to SCT resources and education could serve as a model for meeting unmet information needs for carriers of other genetic conditions.

Association of Periodontal Disease and Edentulism With Hypertension Risk in Postmenopausal Women

BACKGROUND

Multiple cross-sectional epidemiologic studies have suggested an association between periodontal disease and tooth loss and hypertension, but the temporality of these associations remains unclear. The objective of our study was to evaluate the association of baseline self-reported periodontal disease and edentulism with incident hypertension.

METHODS

Study participants were 36,692 postmenopausal women in the Women's Health Initiative-Observational Study who were followed annually from initial periodontal assessment (1998-2003) through 2015 (mean follow-up 8.3 years) for newly diagnosed treated hypertension. Cox proportional hazards regression with adjustment for potential confounders was used to calculate hazard ratios (HRs) and 95% confidence intervals (CIs).

RESULTS

Edentulism was significantly associated with incident hypertension in crude (HR (95% CI) = 1.38 (1.28-1.49)) and adjusted (HR (95% CI) = 1.21 (1.11-1.30)) models. This association was stronger among those <60 years compared to ≥60 years (P interaction 0.04) and among those with <120 mm Hg systolic blood pressure, compared to those with ≥120 mm Hg (P interaction 0.004). No association was found between periodontal disease and hypertension.

CONCLUSIONS

These findings suggest that edentulous postmenopausal women may represent a group with higher risk of developing future hypertension. As such improved dental hygiene among those at risk for tooth loss as well as preventive measures among the edentulous such as closer blood pressure monitoring, dietary modification, physical activity, and weight loss may be warranted to reduce disease burden of hypertension. Further studies are needed to clarify these results and further elucidate a potential role of periodontal conditions on hypertension risk.

An unusual odontogenic infection due to Clostridium subterminale in an immunocompetent patient: A case report and review of the literature

Clostridium subterminale is an anaerobic spore-forming bacterium usually associated with infections in patients who are immunocompromised. This case report focuses on a rare presentation of a multifascial space odontogenic infection associated with the bacterial isolate Clostridium subterminale. The management of an odontogenic infection associated with an isolate of Clostridium subterminale in an immunocompetent female is described, as well as a review of the literature.

Influence of Intimate Partner Violence (IPV) Exposure on Cardiovascular and Salivary Biosensors: Is There a Relationship?

BACKGROUND/PURPOSE

Intimate partner violence (IPV) is a global public health epidemic that initiates/exacerbates health consequences affecting a victim's lifespan. IPV can significantly predispose women to a lifetime risk of developing cardiovascular disease (CVD) due to the effects of stress and inflammation. This study investigates the correlation among IPV exposure, in-vivo CVD events, and inflammatory biomarkers as predictor indices(s) for CVD in female dental patients.

METHODS

Of 37 women enrolled in this study, 19 were African-American (AA) and 18 non-African-American (non-AA) and their ages ranged from 19 to 63 years. IPV-exposure and stress-induced in-vivo CVD events such as Chest Pain (CP) and Heart palpitations were recorded from all enrolled subjects. Cardiovascular events were obtained through surveys by patient self-report. Saliva specimens were obtained from all women and were analyzed for CVD biomarkers using multiplex-ELISA.

RESULTS

The prevalence of IPV was 51% (19/37) and statistically equivalent for AA and non-AA. The results show differences in experience of 1) CP (p < 0.01) and 2) heart palpitations (p < 0.02) when IPV + participants are compared with IPV- AA and non-AA cohorts. Of 10 CVD biomarkers analyzed, significant correlations between IPV+ and IPV- subjects were observed for biomarkers that include Interleukin-1β/sCD40L; TNFα/sCD40L; Myoglobin/IL-1β; CRP/sCD40L; CRP/IL-6; CRP/TNFα; TNFα/siCAM; CRP/MMP9; TNF-α/Adiponectin (p < 0.01).

DISCUSSION/IMPLICATIONS

Analysis of in vivo CVD status showed that significant race/health disparities exist in IPV + cohorts, as well as increased expression of inflammatory mediators, specifically CRP, IL-1β, IL-6, MMP9. Women who have experienced IPV may be a target cohort for primary prevention of CVD. The use of salivary biomarkers and our protocol may provide a less invasive method to help increase identification of victims at risk for IPV and CVD and potentially decrease other health injuries associated with IPV exposure.

How does inflammation drive mutagenesis in colorectal cancer?

Colorectal cancer (CRC) is a major health challenge worldwide. Factors thought to be important in CRC etiology include diet, microbiome, exercise, obesity, a history of colon inflammation and family history. Interventions, including the use of non-steroidal anti-Inflammatory drugs (NSAIDs) and anti-inflammatory agents, have been shown to decrease incidence in some settings. However, our current understanding of the mechanistic details that drive CRC are insufficient to sort out the complex and interacting factors responsible for cancer-initiating events. It has been known for some time that the development of CRC involves mutations in key genes such as p53 and APC, and the sequence in which these mutations occur can determine tumor presentation. Observed recurrent mutations are dominated by C to T transitions at CpG sites, implicating the deamination of 5-methylcytosine (5mC) as a key initiating event in cancer-driving mutations. While it has been widely assumed that inflammation-mediated oxidation drives mutations in CRC, oxidative damage to DNA induces primarily G to T transversions, not C to T transitions. In this review, we discuss this unresolved conundrum, and specifically, we elucidate how the known nucleotide excision repair (NER) and base excision repair (BER) pathways, which are partially redundant and potentially competing, might provide a critical link between oxidative DNA damage and C to T mutations. Studies using recently developed next-generation DNA sequencing technologies have revealed the genetic heterogeneity in human tissues including tumors, as well as the presence of DNA damage. The capacity to follow DNA damage, repair and mutagenesis in human tissues using these emerging technologies could provide a mechanistic basis for understanding the role of oxidative damage in CRC tumor initiation. The application of these technologies could identify mechanism-based biomarkers useful in earlier diagnosis and aid in the development of cancer prevention strategies.

Dental management in patients with hypertension: challenges and solutions

Hypertension is a chronic illness affecting more than a billion people worldwide. The high prevalence of the disease among the American population is concerning and must be considered when treating dental patients. Its lack of symptoms until more serious problems occur makes the disease deadly. Dental practitioners can often be on the frontlines of prevention of hypertension by evaluating preoperative blood pressure readings, performing risk assessments, and knowing when to consider medical consultation of a hypertensive patient in a dental setting. In addition, routine follow-up appointments and patients seen on an emergent basis, who may otherwise not be seen routinely, allow the oral health provider an opportunity to diagnose and refer for any unknown disease. It is imperative to understand the risk factors that may predispose patients to hypertension and to be able to educate them about their condition. Most importantly, the oral health care provider is in a pivotal position to play an active role in the management of patients presenting with a history of hypertension because many antihypertensive agents interact with pharmacologic agents used in the dental practice. The purpose of this review is to provide strategies for managing and preventing complications when treating the patient with hypertension who presents to the dental office.

Intimate Partner Violence and Health Status among Older Women

As the baby boomer generation ages, there are more than 18 million women older than 65 (13.4% of the female population in the United States). More than 41% of these women remain in intimate relationships with their partner and thus become vulnerable to intimate partner violence (IPV). This group of women represents a unique group in the violence literature. Most of this literature has focused on IPV in women of childbearing age. What happens to these women and their relationships as they age? How does IPV differ for women who are not functionally dependent and not relying on their intimate partner for care? This article discusses the epidemiology of IPV, the health effects of IPV, and strategies for identification and intervention by health providers for this group of older women.

Abstract C66: Adverse childhood experiences and breast cancer risk factors in black and white women

Introduction: Adverse childhood experiences (ACE) have been implicated in several adult chronic diseases. ACE may also be associated with reproductive and lifestyle factors and biomarkers associated with breast cancer overall, and with estrogen receptor negative (ER-) disease specifically.

Methods: We examined whether self-reported ACE (verbal, physical, or sexual abuse; household mental illness or substance abuse; domestic violence, parental separation/divorce, and incarcerated household members) was associated with several reproductive and lifestyle breast cancer risk factors including age at menarche and age at first birth, and four biomarkers: adiponectin, C-peptide, high sensitivity C-reactive protein (hsCRP), and insulin-like growth factor-1 (IGF-1). The study population included 16,062 black and white women in the Southern Community Cohort Study. We grouped women into three categories: 0 experiences, 1-2 experiences and 3-10 experiences (high). Cross-sectional associations were analysed using logistic or linear regression.

Results: Women with high ACE were more likely to have: menarche before age 12, ever breastfed, more than two births, first birth before age 18, initiated smoking before age 16, and be current smokers compared to those with no ACE. Parous women with high ACE were 54% more likely to have ever breastfed (OR: 1.54, 95% CI: 1.39, 1.70; p-trend &lt;0.0001) and 65% more likely to have first given birth before age 18 (OR: 1.65, 95% CI: 1.48, 1.85; p-trend &lt;0.0001). ACE was not associated with body mass index (BMI) at enrollment, BMI at age 21, adiponectin, C-peptide or hsCRP levels. ACE was inversely associated with IGF-1. Women with high ACE had mean IGF-1 levels of 104.3 ng/ml compared to 119.2 ng/ml among women with no ACE (p-trend=0.007). Results generally did not differ between Blacks and Whites.

Conclusions: Our findings suggest that ACE is associated with reproductive patterns that have been shown to increase risk of ER- breast cancer. Future work should examine associations between ACE and breast cancer risk according to ER status.

Adult Cancer Risk Behaviors Associated with Adverse Childhood Experiences in a Low Income Population in the Southeastern United States

OBJECTIVES

Adverse childhood experiences (ACE) can affect health in adulthood. We investigate the relationship between childhood experiences and adult cancer risk and screening behaviors in a racially diverse, low income population.

METHODS

Nearly 22,000 adults 40 years and older in the Southern Community Cohort Study were administered the ACE questionnaire. We estimated odds ratios (OR) for the prevalence of smoking, alcohol consumption, BMI and five cancer screening methods in relation to the ACE score.

RESULTS

Over half reported at least one ACE, with percentages higher for women (61%) than men (53%). Higher ACE scores were related to increased prevalence of smoking (ORs 1.25 (1.05-1.50) to 2.33 (1.96-2.77). Little association was seen between rising ACE score and alcohol consumption or BMI, except for a modest trend in morbid obesity (BMI ≥ 40 kg/m2). Mammography and cervical cancer screening decreased with rising ACE scores, but no trends were seen with prostate or colorectal cancer screening.

CONCLUSIONS

Adverse childhood experiences are strong predictors of adult cancer risk behaviors, particularly increased likelihood of smoking, and among women, lower mammography and Pap screening rates.

Community Engagement Studios: A Structured Approach to Obtaining Meaningful Input From Stakeholders to Inform Research

PROBLEM

Engaging communities in research increases its relevance and may speed the translation of discoveries into improved health outcomes. Many researchers lack training to effectively engage stakeholders, whereas academic institutions lack infrastructure to support community engagement.

APPROACH

In 2009, the Meharry-Vanderbilt Community-Engaged Research Core began testing new approaches for community engagement, which led to the development of the Community Engagement Studio (CE Studio). This structured program facilitates project-specific input from community and patient stakeholders to enhance research design, implementation, and dissemination. Developers used a team approach to recruit and train stakeholders, prepare researchers to engage with stakeholders, and facilitate an in-person meeting with both.

OUTCOMES

The research core has implemented 28 CE Studios that engaged 152 community stakeholders. Participating researchers, representing a broad range of faculty ranks and disciplines, reported that input from stakeholders was valuable and that the CE Studio helped determine project feasibility and enhanced research design and implementation. Stakeholders found the CE Studio to be an acceptable method of engagement and reported a better understanding of research in general. A tool kit was developed to replicate this model and to disseminate this approach.

NEXT STEPS

The research core will collect data to better understand the impact of CE Studios on research proposal submissions, funding, research outcomes, patient and stakeholder engagement in projects, and dissemination of results. They will also collect data to determine whether CE Studios increase patient-centered approaches in research and whether stakeholders who participate have more trust and willingness to participate in research.

Physical activity and inflammation in a multiethnic cohort of women

PURPOSE

Many cross-sectional studies using data from a single time point have reported that higher levels of physical activity or fitness are associated with lower levels of inflammatory markers, but data examining change are limited, as are race/ethnicity-specific data. The purpose of this study was to examine the associations between physical activity and inflammation assessed at two time points among women of different race/ethnicities.

METHODS

A total of 1355 postmenopausal women (301 whites, 300 blacks, 300 Hispanics, 300 Asians/Pacific Islanders, and 154 American Indians) age 50-79 yr were studied. Participants were from 40 US cities and were free of cardiovascular disease and cancer. At baseline and year 3, women reported their recreational physical activities and provided blood samples, which were analyzed for several inflammatory markers.

RESULTS

In cross-sectional analyses, after adjusting for several potential confounders including body mass index, higher physical activity levels were generally related to lower inflammatory marker concentrations. For example, P values for a linear trend of lower C-reactive protein levels across physical activity tertiles at baseline were <0.0001 in all women and 0.94, 0.09, 0.002, 0.20, and 0.10, respectively, for the five race/ethnic groups listed above. For interleukin 6, the corresponding P values were <0.0001, 0.0007, 0.01, 0.03, 0.37, and 0.004, respectively, at baseline. Relationships at year 3 were similar to baseline. However, there was no relation between changes in physical activity and changes in inflammatory markers during the 3-yr period.

CONCLUSIONS

Among middle-age and older women overall, there were strong, inverse, cross-sectional associations between physical activity level and inflammatory markers. However, changes in inflammatory markers were unrelated to changes in physical activity. These data suggest a noncausal association between physical activity and inflammatory markers.

Toward a positive aging phenotype for older women: observations from the women's health initiative

BACKGROUND

To develop a positive aging phenotype, we undertook analyses to describe multiple dimensions of positive aging and their relationships to one another in women 65 years of age and older and evaluate the performance of individual indicators and composite factors of this phenotype as predictors of time to death, years of healthy living, and years of independent living.

METHODS

Data from Women's Health Initiative clinical trial and observational study participants ages 65 years and older at baseline, including follow-up observations up to 8 years later, were analyzed using descriptive statistics and principal components analysis to identify the factor structure of a positive aging phenotype. The factors were used to predict time to death, years of healthy living (without hospitalization or diagnosis of a serious health condition), and years of independent living (without nursing home admission or use of special services).

RESULTS

We identified a multidimensional phenotype of positive aging that included two factors: Physical-Social Functioning and Emotional Functioning. Both factors were predictive of each of the outcomes, but Physical-Social Functioning was the strongest predictor. Each standard deviation of increase in Physical-Social Functioning was accompanied by a 23.7% reduction in mortality risk, a 19.4% reduction in risk of major health conditions or hospitalizations, and a 26.3% reduction in risk of dependent living.

CONCLUSIONS

Physical-Social Functioning and Emotional Functioning constitute important components of a positive aging phenotype. Physical-Social Functioning was the strongest predictor of outcomes related to positive aging, including years of healthy living, years of independent living, and time to mortality.

Early detection of illicit drug use in teenagers

The illicit use of drugs, including alcohol, by teenagers has been extensively studied and documented. It is not uncommon for teenagers to be involved in illicit drug use before exhibiting signs and symptoms of drug use. Unsuspecting parents may be unaware of drug use in their children. The authors' objective in this article is to review the literature on illicit drug use in teenagers and highlight the risk factors for teen involvement. The authors also review the warning signs that a teen is using illicit drugs. The aim of this article is to assist parents and healthcare workers involved in substance use intervention programs to be more aware of these risk factors and warning signs in order to adopt early screening and intervention measures.

Racial differences in colorectal cancer incidence and mortality in the Women's Health Initiative

BACKGROUND

Colorectal cancer (CRC) incidence and mortality rates are higher in African-Americans as compared with other racial/ethnic groups. The women's health initiative (WHI) study sample was used to determine whether differences in CRC risk factors explain racial/ethnic differences in incidence and mortality.

METHODS

The WHI is a longitudinal study of postmenopausal women recruited from 40 centers. Baseline questionnaires were used to collect sociodemographic and health status information. All CRC diagnoses were centrally adjudicated. Cox regression models were used to compute hazard ratios (HRs) and 95% confidence intervals (CIs) for invasive CRC by race/ethnicity.

RESULTS

The study sample included 131,481 (83.7%) White, 14,323 (9.1%) African-American, 6,362 (4.1%) Hispanic, 694 (0.4%) Native American and 4,148 (2.6%) Asian/Pacific Islanders. After a mean follow-up of 10.8 years (SD 2.9), CRC incidence was the highest in African-Americans (annualized rate = 0.14%), followed by Whites and Native Americans (0.12% each), Asian/Pacific Islanders (0.10%), and Hispanics (0.08%). After adjustment for age and trial assignment, Hispanics had a lower risk compared with Whites, HR 0.73 (95% CI: 0.54-0.97) (P = 0.03), and African-Americans had a marginally greater risk, HR 1.16 (95% CI: 0.99-1.34), P = 0.06. Multivariable adjustment attenuated the difference in incidence between African-Americans and Whites (HR 0.99, 95% CI: 0.82-1.20), while strengthening the lower HR for Hispanics (HR 0.68, 95% CI: 0.48-0.97).

CONCLUSIONS

African-American/White differences in CRC risk are likely due to sociodemographic/cultural factors other than race.

IMPACT

A number of modifiable exposures could be a focus for reducing CRC risk in African-Americans.

Abstract 1922: Ethnic and racial differences in colorectal cancer

Introduction: The Women's Health Initiative (WHI) provides a robust database to determine whether differences in known colorectal cancer (CRC) risk factors influence ethnic and racial differences in incidence and mortality. Methods: The WHI is a multi-center longitudinal study of postmenopausal women age 50-79 years recruited from 40 centers across the US. Baseline self-administered questionnaires were used to collect self-identified ethnicity or race, other demographics and health status. Cancer screening information was collected annually and cancer diagnoses were centrally adjudicated. Cox proportional hazards regression was used to compute hazard ratios (HRs) and 95% confidence intervals (CIs) for invasive CRC by ethnicity/race. Results: The ethnic and racial composition of the sample is 131,481 (84%) White, 14,323 (9%) African American (AA), 6,362 (4%) Hispanic, 694 (&lt;1%) Native American and 4,148 (3%) Asian/Pacific Islander (API). After a mean follow-up of 10.8 years (SD 2.9), CRC incidence was highest among AA (annualized percent 0.14%), followed by Whites and Native Americans (0.12% each), API (0.10%) and Hispanics (0.08%). After adjustment for age and cohort assignment, Hispanics had a lower risk of CRC compared to Whites, HR 0.73 (95% CI: 0.54-0.97) (p=0.03), and AA had a marginally greater risk, HR 1.16 (95% CI: 0.99-1.34), p=0.06. Adjustment for other covariates, eliminated the difference in incidence between AA and Whites (HR 0.99, 95% CI: 0.82-1.20), however the difference in incidence between Hispanics and Whites increased (HR 0.68, 95% CI: 0.48-0.97), p = 0.03. Conclusions: Differences in CRC risk between Hispanics and Whites are not explained by sociodemographic or behavioral factors in the WHI cohort.

Psychosocial effects of physical and verbal abuse in postmenopausal women

PURPOSE

The purpose of this study was to examine the psychological effects of physical and verbal abuse in a cohort of older women.

METHODS

This observational cohort study was conducted at 40 clinical sites nationwide that are part of the Women's Health Initiative (WHI) Observational Study. We surveyed 93,676 women aged 50 to 79 years using the mental health subscales and the combined mental component summary (MCS) score of the RAND Medical Outcomes Study 36-item instrument.

RESULTS

At baseline, women reporting exposure to physical abuse only, verbal abuse only, or both physical and verbal abuse had a greater number of depressive symptoms (1.6,1.6, and 3 more symptoms, respectively) and lower MCS scores (4.6, 5.4, and 8.1 lower scores, respectively) than women not reporting abuse. Compared with women who had no exposure to abuse, women had a greater increase in the number of depressive symptoms when they reported a 3-year incident exposure to physical abuse only (0.2; 95% confidence interval [CI], -0.21 to 0.60), verbal abuse only (0.18; 95% CI, 0.11 to 0.24), or both physical and verbal abuse (0.15; 95% CI, -0.05 to 0.36); and they had a decrease in MCS scores when they reported a 3-year incident exposure to physical abuse only (-1.12; 95% CI, -2.45 to 0.12), verbal abuse only (-0.55; 95% CI, -0.75 to -0.34), and both physical and verbal abuse (-0.44; 95% CI, -1.11 to -0.22) even after adjustment for sociodemographic characteristics.

CONCLUSION

Exposure to abuse in older, functionally independent women is associated with poorer mental health. The persistence of these findings suggests that clinicians need to consider abuse exposure in their older female patients who have depressive symptoms. Clinicians caring for older women should identify women at risk for physical and verbal abuse and intervene appropriately.

The relationship between cognitive function and physical performance in older women: results from the women's health initiative memory study

BACKGROUND

Cognitive function and physical performance are associated, but the common sequence of cognitive and physical decline remains unclear.

METHODS

In the Women's Health Initiative Memory Study (WHIMS) clinical trial, we examined associations at baseline and over a 6-year follow-up period between the Modified Mini-Mental State (3MS) Examination and three physical performance measures (PPMs): gait speed (meters/second), chair stands (number of stands in 15 seconds), and grip strength (kilograms). Using mixed models, we examined the baseline 3MS as predictor of change in PPM, change in the 3MS as predictor of change in PPM, and baseline PPM as predictors of 3MS change.

RESULTS

Among 1,793 women (mean age = 70.3 years, 89% white, and mean 3MS score = 95.1), PPM were weakly correlated with 3MS-gait speed: r = .06, p = .02; chair stands: r = .09, p < .001; and grip strength: r = .10, p < .001. Baseline 3MS score was associated with subsequent PPM decline after adjustment for demographics, comorbid conditions, medications, and lifestyle factors. For every SD (4.2 points) higher 3MS score, 0.04 SD (0.04 m/s) less gait speed and 0.05 SD (0.29 kg) less grip strength decline is expected over 6 years (p </= .01 both). Changes in 3MS and PPM were associated, particularly with chair stands and grip strength (p < .003 both). Baseline PPMs were not associated with subsequent 3MS change.

CONCLUSIONS

Baseline global cognitive function and change in global cognitive function were associated with physical performance change, but baseline physical performance was not associated with cognitive change in this cohort. These analyses support the hypothesis that cognitive decline on average precedes or co-occurs with physical performance decline.

Multiethnic Perspectives on Elder Mistreatment

PURPOSE

We conducted this study to understand the interpretations of elder mistreatment (EM) in multiethnic older adults.

DESIGN AND METHODS

Focus group sessions were held with three ethnically homogenous groups (n = 18) and a group of elder care professionals (n = 6) eliciting responses to vignettes depicting various types of elder mistreatment. Qualitative analysis of focus group transcripts was performed to define EM occurrence, its severity, and to identify the perpetrator and victim.

RESULTS

Four main categories emerged: social expectations, caregiver expectations, victim characteristics, and characteristics of the interaction. Themes included issues of gender roles, filial obligations, martial commitments, and ageism as features of the vignette discussions. Professional and lay caregiver issues were features of the caregiver expectations. Mental capacity, physical dependency, physical attributes, and complicity were the victim characteristics discussed. The characteristics of the interaction that were identified included resistance to care, retaliation, habitual occurrence, and perpetrator intent.

IMPLICATIONS

Older adults identify multiple factors influencing the interpretation of elder mistreatment. These factors may determine strategies for future EM intervention.

Environmental influences on cardiovascular health

A growing body of evidence indicates that the respiratory system is not the only target organ that may be injured by the inhalation of airborne particulate matter. Increased attention is now focused on research showing a link between particulate matter air pollution and cardiovascular morbidity and mortality, raising complex questions about the mechanism by which dirty air affects the heart. At the same time, the population at risk of cardiovascular continues to grow, including the obese, overweight, hypertensive and senior citizens. This pervasive and growing public health and medical care issue elevates into sharp relief the need for physicians and other healthcare practitioners to understand the clinical consequences exposure to particulate air pollution. This review is designed to further that understanding.

Nanotechnology and nanomedicine: a primer

Nanosciences and nanotechnology are transforming a wide array of products and services that have the potential to enhance the practice of medicine and improve public health. But there are a number of health, safety and environmental issues to be addressed. This review summarizes some basic facts about nanotechnology and cites examples of its application to medicine and public health.

Suboptimal Medication Use and Mortality in an Older Adult Community-Based Cohort: Results From the Hispanic EPESE Study

BACKGROUND

Numerous methods have been used to evaluate medication management quality in older adults; however, their predictive validities are unknown. Major medication quality indicators include polypharmacy, drug-drug interactions, and inappropriate medication use. To date, no study has attempted to evaluate the three approaches systematically or the effect of each approach on mortality in a Hispanic population. Our objective was to evaluate the relationship between polypharmacy, drug-drug interactions, and inappropriate medication use on the mortality of a community-based population of Mexican American older adults.

METHODS

We used a life table survival analysis of a longitudinal survey of a representative sample of 3,050 older Mexican Americans of whom 1,823 were taking prescription and over-the-counter medications.

RESULTS

After adjustment for relevant covariates, use of more than four different medications (polypharmacy) was independently associated with mortality. The presence of major drug interactions and the use of inappropriate medications were not significantly associated with mortality in our study sample.

CONCLUSION

Polypharmacy (>4 medications) is significantly associated with mortality in Mexican American older adults. This community-based study is the first to demonstrate a direct association between polypharmacy and mortality in this population.

Potential Mediators of Ethnic Differences in Physical Activity in Older Mexican Americans and European Americans: Results from the San Antonio Longitudinal Study of Aging

Factors were examined that might explain reported ethnic differences in leisure time physical activity (LTPA) between Mexican Americans (MAs) and European Americans (EAs). Data were from a random sample of 749 community-dwelling MAs and EAs, aged 65 and older, who participated in the San Antonio Longitudinal Study of Aging (SALSA) baseline examination. Variables examined included LTPA measured as kilocalories of energy expended per week, contextual variables (age, sex, socioeconomic status (SES), acculturation/structural assimilation), psychosocial measures (self-esteem, mastery, perceived health control), lifestyle variables (fat avoidance, current alcohol drinker, years smoking, body mass index (BMI)), and presence of chronic diseases (diabetes mellitus, angina pectoris, myocardial infarction, stroke, hypertension, arthritis, chronic obstructive pulmonary disease, depression, mild cognitive impairment). Hierarchical multiple regression was used to examine potential mediators of the ethnic group-LTPA association. EAs expended almost 300 kcal/wk more energy than did MAs (1,287 kcal/wk vs 1,001 kcal/wk). SES and psychosocial (self-esteem), lifestyle (fat avoidance, smoking, BMI), and disease (depression) factors that vary by SES explained this ethnic difference. In MAs, structural assimilation, but not acculturation, was significantly associated with LTPA independent of SES. Self-esteem, BMI, and depression explained this association. Psychosocial resources, lifestyle behaviors, and depression explain differences in LTPA between older MAs and EAs. Interventions to increase LTPA in both ethnic groups should be targeted especially at women and persons who have low self-esteem, smoke, and are obese or depressed. In MAs, additional emphasis should be focused on those who are less structurally assimilated into the broader American society.

Prevalence and 3-year incidence of abuse among postmenopausal women

OBJECTIVES

We examined prevalence, 3-year incidence, and predictors of physical and verbal abuse among postmenopausal women.

METHODS

We used a cohort of 91,749 women aged 50 to 79 years from the Women's Health Initiative. Outcomes included self-reported physical abuse and verbal abuse.

RESULTS

At baseline, 11.1% reported abuse sometime during the prior year, with 2.1% reporting physical abuse only, 89.1% reporting verbal abuse only, and 8.8% reporting both physical and verbal abuse. Baseline prevalence was associated with service occupations, having lower incomes, and living alone. At 3-year follow-up, 5.0% of women reported new abuse, with 2.8% reporting physical abuse only, 92.6% reporting verbal abuse only, and 4.7% reporting both physical and verbal abuse.

CONCLUSIONS

Postmenopausal women are exposed to abuse at similar rates to younger women; this abuse poses a serious threat to their health.

Prevalence and severity of urinary incontinence in elderly Mexican-American women

OBJECTIVES

To measure prevalence and characteristics of urinary incontinence in older Mexican-American women.

DESIGN

Cross-sectional analysis of a longitudinal survey of a representative sample of older Mexican Americans.

SETTING

Five southwestern states in the United States.

PARTICIPANTS

A total of 1589 Mexican-American women, aged 65 and older who were part of the Hispanic Established Population for the Epidemiologic Study of the Elderly.

MEASUREMENTS

Self-reported psychosocial, demographic, and health variables; self-reported history of symptoms of urinary incontinence.

RESULTS

Two hundred thirty-nine (15%) of the 1589 Mexican-American women reported having urinary incontinence. Almost 33% reported urge incontinence symptoms, 10% reported stress incontinence symptoms, and 42% had symptoms suggestive of mixed incontinence. Thirty-five percent of subjects reported incontinence episodes with moderate to large amounts of urine loss, and 15% reported that their urinary symptoms kept them from engaging in social activities. Age and body mass index were risk factors for incontinence (P=.02 and P=.03, respectively).

CONCLUSION

This is the first community-based survey examining rates of urinary incontinence in Mexican-American women. The prevalence of urinary incontinence may be lower in older Mexican-American women than in the general population. They may also have a higher percentage of urge as opposed to stress incontinence symptoms and may suffer from moderate to large volumes of urine loss associated with their incontinence episodes.

The effects of widowhood on physical and mental health, health behaviors, and health outcomes: The Women's Health Initiative

This study examined whether widowhood was associated with physical and mental health, health behaviors, and health outcomes using a cross-sectional (N=72,247) and prospective (N=55,724) design in women aged 50-79 years participating in the Women's Health Initiative observational study (85.4% White). At baseline, married women reported better physical and mental health and generally better health behaviors than widowed women. Whereas women who remained married over the 3-year period showed stability in mental health, recent widows experienced marked impairments and longer term widows showed stability or slight improvements. Both groups of widows reported more unintentional weight loss over the 3-year period. Changes in physical health and health behaviors were inconsistent, with generally small effect sizes. Findings underscore the resilience of older women and their capacity to reestablish connections, but point to the need for services that strengthen social support among women who have difficulty during this transition.

Barriers to and benefits of leisure time physical activity in the elderly: differences across cultures

The purpose of this study was to compare ethnic differences in attitudes toward barriers and benefits of leisure-time physical activity (LTPA) in sedentary elderly Mexican (MAs) and European Americans (EAs). An in-home, cross-sectional survey was performed on 210 community-dwelling elders from 10 primary care practices in south Texas that are part of the South Texas Ambulatory Research Network, a practice-based research network. Analytical variables included ethnicity, age, sex, income, education, marital status, and LTPA. Fisher exact test was used to analyze the 100 sedentary elders (LTPA <500 kcal/wk; 63 MAs and 37 EAs). Self-consciousness and lack of self-discipline, interest, company, enjoyment, and knowledge were found to be the predominant barriers to LTPA in both groups. Both groups held similar beliefs about benefits gained from exercise, such as improved self-esteem, mood, shape, and health, but the beliefs about the positive benefits of exercise were more prevalent in MAs. These findings remained after adjusting for age, income, education, marital status, and sex. Some might think that a major barrier lies in misconception about benefits of LTPA, but in this study, both ethnic groups were accurate in their perceived benefits of LTPA. When attempting to engage elderly in LTPA, it is important not only to consider what barriers exist but also what beliefs about the benefits exist.

Characteristics of Mexican-American elders with dementia presenting to a community-based memory evaluation program

OBJECTIVE

To determine sociodemographic characteristics associated with the initial presentation of Mexican-American elders to a community-based memory evaluation clinic.

METHODS

Retrospective review of the charts of 89 Mexican Americans presenting consecutively to an outpatient memory evaluation clinic in San Antonio, Texas.

PRINCIPAL FINDINGS

Mexican Americans presented for evaluation with more moderate-to-severe cognitive impairment than previously reported. They also tended to have high levels of IADL (83.1%) and gait/balance (52.3%) impairment, as well as high levels of depressive symptoms (63.1%).

CONCLUSIONS

Mexican Americans present for initial evaluation for memory decline with moderate-to-severe cognitive decline and significant dementia-associated co-morbidities. In Mexican Americans, caregiver burden, fall risks, depressive symptoms, and need for IADL support should be addressed on the initial visit for memory decline.

Early recognition and treatment of calciphylaxis

Calciphylaxis is a condition with a high mortality rate that is often found in patients with renal failure. It is characterized by soft tissue calcification and painful skin ulceration. A serum calcium-phosphorus product of more than 60 mg2/dl2 indicates great risk for calciphylaxis. The diagnosis is made on the basis of an incisional biopsy showing calcification of the small, subcutaneous arteries.

Walking compared with vigorous exercise for the prevention of cardiovascular events in women

BACKGROUND

The role of walking, as compared with vigorous exercise, in the prevention of cardiovascular disease remains controversial. Data for women who are members of minority racial or ethnic groups are particularly sparse.

METHODS

We prospectively examined the total physical-activity score, walking, vigorous exercise, and hours spent sitting as predictors of the incidence of coronary events and total cardiovascular events among 73,743 postmenopausal women 50 to 79 years of age in the Women's Health Initiative Observational Study. At base line, participants were free of diagnosed cardiovascular disease and cancer, and all participants completed detailed questionnaires about physical activity. We documented 345 newly diagnosed cases of coronary heart disease and 1551 total cardiovascular events.

RESULTS

An increasing physical-activity score had a strong, graded, inverse association with the risk of both coronary events and total cardiovascular events. There were similar findings among white women and black women. Women in increasing quintiles of energy expenditure measured in metabolic equivalents (the MET score) had age-adjusted relative risks of coronary events of 1.00, 0.73, 0.69, 0.68, and 0.47, respectively (P for trend, <0.001). In multivariate analyses, the inverse gradient between the total MET score and the risk of cardiovascular events remained strong (adjusted relative risks for increasing quintiles, 1.00, 0.89, 0.81, 0.78, and 0.72, respectively; P for trend <0.001). Walking and vigorous exercise were associated with similar risk reductions, and the results did not vary substantially according to race, age, or body-mass index. A brisker walking pace and fewer hours spent sitting daily also predicted lower risk.

CONCLUSIONS

These prospective data indicate that both walking and vigorous exercise are associated with substantial reductions in the incidence of cardiovascular events among postmenopausal women, irrespective of race or ethnic group, age, and body-mass index. Prolonged sitting predicts increased cardiovascular risk.

Inflammatory biomarkers, hormone replacement therapy, and incident coronary heart disease: prospective analysis from the Women's Health Initiative observational study

CONTEXT

Postmenopausal hormone replacement therapy (HRT) has been shown to elevate C-reactive protein (CRP) levels. Several inflammatory biomarkers, including CRP, are associated with increased cardiovascular risk. However, whether the effect of HRT on CRP represents a clinical hazard is unknown.

OBJECTIVES

To assess the association between baseline levels of CRP and interleukin 6 (IL-6) and incident coronary heart disease (CHD) and to examine the relationship between baseline use of HRT, CRP, and IL-6 levels as they relate to subsequent vascular risk.

DESIGN, SETTING, AND PARTICIPANTS

Prospective, nested case-control study of postmenopausal women, forming part of the Women's Health Initiative, a large, nationwide, observational study. Among 75 343 women with no history of cardiovascular disease or cancer, 304 women who developed incident CHD were defined as cases and matched by age, smoking status, ethnicity, and follow-up time with 304 study participants who remained event free during a median observation period of 2.9 years.

MAIN OUTCOME MEASURE

Incidence of first myocardial infarction or death from CHD.

RESULTS

Median baseline levels of CRP (0.33 vs 0.25 mg/dL; interquartile range [IQR], 0.14-0.71 vs 0.10-0.47; P<.001) and IL-6 (1.81 vs 1.47 pg/mL; IQR, 1.30-2.75 vs 1.05-2.15; P<.001) were significantly higher among cases compared with controls. In matched analyses, the odds ratio (OR) for incident CHD in the highest vs lowest quartile was 2.3 for CRP (95% confidence interval [CI], 1.4-3.7; P for trend =.002) and 3.3 for IL-6 (95% CI, 2.0-5.5; P for trend <.001). After additional adjustment for lipid and nonlipid risk factors, both inflammatory markers were significantly associated with a 2-fold increase in odds for CHD events. As anticipated, current use of HRT was associated with significantly elevated median CRP levels. However, there was no association between HRT and IL-6. In analyses comparing individuals with comparable baseline levels of either CRP or IL-6, those taking or not taking HRT had similar CHD ORs. In analyses stratified by HRT, we observed a positively graded relationship between plasma CRP levels and the OR for CHD among both users and nonusers of HRT across the full spectrum of baseline CRP.

CONCLUSIONS

These prospective findings indicate that CRP and IL-6 independently predict vascular events among apparently healthy postmenopausal women and that HRT increases CRP. However, use or nonuse of HRT had less importance as a predictor of cardiovascular risk than did baseline levels of either CRP or IL-6.

Barriers to follow-up of hypertensive patients

Lack of follow-up care for hypertension adversely affects health in urban communities. The authors designed this study to (1) evaluate the effectiveness of a specialized intervention program for hypertension follow-up and (2) evaluate the associations with loss to follow-up. They evaluated factors related to loss to follow-up to either a routine care medical clinic or a special primary care intervention program (the Competitive Initiative Program [CIP]). They also conducted interviews to provide in-depth information on the barriers to this program. They found that patients referred through the CIP were significantly more likely to receive follow-up care through a primary care provider. Cost of care, long waiting times, lack of physician continuity, and more pressing priorities explained the lack of follow-up care. Despite a program to provide health care at no cost to patients, lack of insurance and worries about cost are described as barriers to adequate follow-up for hypertension treatment.

Patterns of prescription drug utilization in elder Mexican Americans: results from the Hispanic EPESE Study. Established Population for the Epidemiologic Study of the Elderly

The objective of this study was to determine the patterns of prescription medication usage among community-dwelling Mexican-American elders. This was a cross-sectional survey of a regional probability sample of 2,895 community-dwelling Mexican Americans, aged 65 and over. Of the sample, 58.1% used at least one prescribed medication within the two weeks prior to their participation in the study. Women were significantly more likely than men to use analgesics, non-steroidal anti-inflammatory agents, prescription nutritional supplements, and other central nervous system and endocrine medications. Subjects aged 75 and over were more likely to use cardiovascular medications, nutritional supplements, ophthalmic preparations and antihistamines, while those in the age groups 65-69 and 70-74 were more likely to use hypoglycemic and endocrine medications. Interestingly, there was a significantly decreased usage of hypoglycemic medications in the older age group (aged 75 and over) as compared with the younger age groups (65-69 and 69-74). This may indicate that Mexican American elders are dying at younger ages from complications related to diabetes mellitus and are not alive to use hypoglycemic medications at ages 75 and over. Also, men used more hypoglycemic medication than women (77% vs 70%). There was no relationship between use of medication and severity of diabetic illness.
