Surgical Residents in the Battle Against COVID-19.

PERSPECTIVES: In times of public health crises, medical residency program leaders are responsible to maintain the wellbeing of their residents and ensure uninterrupted training. COVID-19 caused significant impact on healthcare industry, depleting resources and manpower, which led to disruption to graduate medical education and residency training. Surgical residents were affected by the pandemic both by reduced operative opportunities in most training centers and inducing stress and concerns about safety and wellbeing among residents. Spread of the SARS-Cov-2 was naturally accompanied with a gradual decrease in numbers of healthcare personnel which consequently increased the burden on residents. During these times of crisis and uncertainty, it is crucial that residency programs find alternative learning opportunities and deploy pre-designed, dynamic operational strategies to ensure high quality surgical services while optimizing resident safety and wellbeing. The COVID-19 crisis was a natural call for the essential need to add another dimension to residency competencies, which is Crisis-based learning and practice. Times of public health crisis are opportunities to reflect on the medical practice from an interdisciplinary and interprofessional perspective and train the residents to function as part of a larger, globally responsible team. It also calls upon adopting innovative instructional and learning strategies such as utilizing digital and online learning tools to complement learning. A holistic approach to the crisis was taken by the surgical residency program at the University of Illinois in Chicago, which addressed the issue from a resident, hospital, and public health standpoints. An operational strategy was introduced to optimize resident safety, maximize learning opportunities, support other non-surgical services, and promote online teaching and learning. This strategy is meant to serve as a dynamic reference for surgical residency programs and as an infrastructure for dealing with this and any upcoming healthcare crises in an efficient and resident-centered way.

Anxiety Symptoms, Depressive Symptoms, and Traditional Chinese Medicine Use in U.S. Chinese Older Adults.

This study examined the association between anxiety symptoms, depressive symptoms, and Traditional Chinese Medicine (TCM) use among U.S. Chinese older adults. Data was obtained from the Population Study of Chinese Elderly in Chicago (N = 3157; mean age = 72.8). Anxiety symptoms were assessed with the Hospital Anxiety and Depression Scale (HADS-A). Depressive symptoms were assessed with the Patient Health Questionnaire (PHQ-9). TCM modalities included herbal products, acupuncture, massage therapy, Taichi, and other types of TCM. Although not significant, there was a trend indicating that higher levels of anxiety symptoms showed a higher rate of acupuncture use and massage therapy. Older Chinese Americans with depressive symptoms were more likely to use acupuncture and massage therapy; and they were less likely to use other TCM. Future research is needed to identify reasons for TCM use; and how these factors mediate or moderate the relationship between psychiatric symptoms and TCM use.

Neighborhood Physical Disorder and Adverse Pregnancy Outcomes among Women in Chicago: a Cross-Sectional Analysis of Electronic Health Record Data.

Adverse pregnancy outcomes increase infants' risk for mortality and future health problems. Neighborhood physical disorder may contribute to adverse pregnancy outcomes by increasing maternal chronic stress. Google Street View technology presents a novel method for assessing neighborhood physical disorder but has not been previously examined in the context of birth outcomes. In this cross-sectional study, trained raters used Google's Street View imagery to virtually audit a randomly sampled block within each Chicago census tract (n = 809) for nine indicators of physical disorder. We used an item-response theory model and spatial interpolation to calculate tract-level neighborhood physical disorder scores across Chicago. We linked these data with geocoded electronic health record data from a large, academic women's hospital in Chicago (2015-2017, n = 14,309 births). We used three-level hierarchical Poisson regression to estimate prevalence ratios for the associations of neighborhood physical disorder with preterm birth (overall and spontaneous), small for gestational age (SGA), and hypertensive disorder of pregnancy (HDP). After adjustment for maternal sociodemographics, multiparity, and season of birth, living in a neighborhood with high physical disorder was associated with higher prevalence of PTB, SGA, and HDP (prevalence ratios and 95% confidence intervals 1.21 (1.06, 1.39) for PTB, 1.13 (1.01, 1.37) for SGA, and 1.23 (1.07, 1.42) for HDP). Adjustment for neighborhood poverty and maternal health conditions (e.g., hypertension, diabetes, asthma, substance use) attenuated associations. Results suggest that an adverse neighborhood physical environment may contribute to adverse pregnancy outcomes. However, future work is needed to disentangle the unique contribution of physical disorder from other characteristics of disadvantaged neighborhoods.

Obstruction predicts worse long-term outcomes in stage III colon cancer: A secondary analysis of the N0147 trial.

BACKGROUND: Patients with colon cancer often present with obstruction. Large series have reported obstruction among the high-risk features, yet prospective data on its specific prognostic influence are lacking. We hypothesized that obstruction is an independent risk factor for poor prognosis in patients with stage III colon cancer. METHODS: N0147 was a trial conducted between 2004 and 2009 that randomly assigned patients with stage III colon cancer to adjuvant regimens of folinic acid (leucovorin calcium), fluorouracil, and oxaliplatin or fluorouracil, leucovorin, and irinotecan, with or without cetuximab. Patient-level data from the control chemotherapy-only arms were obtained. Patient, tumor, and treatment characteristics were abstracted. Disease-free survival and overall survival were estimated by the Kaplan-Meier method. Proportions were compared by χ2 and Fisher exact tests. Univariable and multivariable survival analyses were performed using Cox proportional hazards models. RESULTS: Of 1,543 patients with stage III colon cancer, 250 (16.2%) presented with obstruction. Patients with obstruction were equally likely to complete 12 cycles of adjuvant chemotherapy (75.9% vs 77.1%, P = .6). With median follow-up time of 30.9 months among survivors, five-year overall survival and disease-free survival were worse among patients with obstruction (overall survival 67.7% vs 78.0%, P < .001; disease-free survival 53.9% vs 67.0%, P < .0001). On multivariable analysis, obstruction remained significantly associated with worse survival after adjusting for T stage, N stage, performance status, age, sex, histologic grade, and body mass index (overall survival hazard ratio 1.57, 95% confidence interval 1.12-2.20, P = .001; disease-free survival 1.52, 95% confidence interval 1.18-1.95, P < .001). CONCLUSION: In this prospectively followed cohort of patients with stage III colon cancer treated with adjuvant chemotherapy, obstruction was associated with recurrence and worse survival. Moreover, this effect was independent of T and N stage and histologic grade. These results suggest that obstruction should be incorporated into novel risk-stratification models.

Prevalence of a Cefazolin Inoculum Effect Associated with blaZ Gene Types among Methicillin-Susceptible Staphylococcus aureus Isolates from Four Major Medical Centers in Chicago.

The efficacy of cefazolin with high-inoculum methicillin-susceptible Staphylococcus aureus (MSSA) infections remains in question due to therapeutic failure inferred as being due to an inoculum effect (InE). This study investigated the local prevalence of a cefazolin InE (CInE) and its association with staphylococcal blaZ gene types among MSSA isolates in the Chicago area. Four medical centers in Chicago, IL, contributed MSSA isolates. Cefazolin MICs (C-MIC) were determined at 24 h by the broth microdilution method using a standard inoculum (SI; 5 × 105 CFU/ml) and a high inoculum (HI; 5 × 107 CFU/ml). The CInE was defined as (i) a ≥4-fold increase in C-MIC between SI and HI and/or (ii) a pronounced CInE, i.e., a nonsusceptible C-MIC of ≥16 µg/ml at HI. PCR was used to amplify the blaZ gene, followed by agarose gel electrophoresis and sequencing to determine the gene type. Approximately 269 MSSA isolates were included. All but one isolate were susceptible to cefazolin at SI, and 97% remained susceptible at HI. A total of 196 isolates (73%) were blaZ positive, with the blaZ types led by gene type C (40%). CInE was seen in 45 blaZ-positive isolates (23%), with 44 (22%) presenting a ≥4-fold increase in C-MIC (SI to HI) and 5 (3%) a pronounced CInE. Four of the five met both definitions of CInE, two of which expressed the type A gene. The prevalence of a pronounced CInE associated with the type A blaZ gene from MSSA isolates in Chicago is low. Our predilection for cefazolin use, even early in the management of hospitalized MSSA infections, is tenable.

Prevalence and Predictors of Low Serum 25-Hydroxyvitamin D among Female African-American Breast Cancer Survivors.

BACKGROUND: African-American breast cancer survivors commonly demonstrate low serum 25-hydroxyvitamin D (25(OH)D). Decreased cutaneous conversion, high levels of adiposity, and even breast cancer treatment may influence vitamin D status. Previous investigations have analyzed African-American women in aggregate with other breast cancer survivors and have not comprehensively addressed these influential factors. OBJECTIVES: To determine the prevalence of low serum 25(OH)D in an exclusively African-American cohort of female breast cancer survivors with overweight/obesity and to evaluate the role of ultraviolet (UV) light exposure, body composition, and dietary sources of vitamin D on serum 25(OH)D levels. DESIGN: Cross-sectional. PARTICIPANTS: Pre- and postmenopausal African-American breast cancer survivors (n=244) were recruited from various neighborhoods in the city of Chicago, IL, between September 2011 and September 2014 for a larger weight loss trial. MAIN OUTCOME MEASURES: Demographic, clinical, anthropometric (body mass index [calculated as kg/m2], waist circumference, and hip circumference), blood specimen, dietary intake (food frequency questionnaire), and sun behavior data were collected by trained study personnel before trial participation. Dual-energy x-ray absorptiometry was used to quantify adiposity (total, percentage, regional, visceral) and lean mass. Serum 25(OH)D was used as the biomarker reflective of vitamin D status. STATISTICAL ANALYSES: Mean (±standard deviation), frequencies, and multivariate linear regression modeling. RESULTS: The average participant was 57.4 years old (±10.0), 6.9 years (±5.2) from initial breast cancer diagnosis with a body mass index of 36.2 (±6.2). The majority of participants (60%) reported habitual oral vitamin D supplementation with mean intake of 327 IU (±169). Vitamin D deficiency was prevalent in 81% and 43%, when the cut points of the Endocrine Society (<30 ng/mL or <75 nmol/L) and the Institute of Medicine (<20 ng/mL or <50 nmol/L) were applied, respectively. A multivariate model adjusting for age, seasonality of blood draw, total energy intake, use of supplemental vitamin D, darker skin pigmentation, breast cancer stage, and waist-to-hip ratio was able to explain 28.8% of the observed variance in serum 25(OH)D concentrations. No significant associations were detected for body mass index or any dual-energy x-ray absorptiometry measures of body composition. CONCLUSIONS: Considering the number of women who endorsed use of vitamin D supplementation, the prevalence of vitamin D deficiency among these African-American breast cancer survivors was high. Vitamin D supplementation, sun behavior, and waist-to-hip ratio may serve as future points of intervention to improve the vitamin D status of this minority survivor population.

A Longitudinal Analysis of Antiretroviral Adherence Among Young Black Men Who Have Sex With Men.

PURPOSE: Young black men who have sex with men (YBMSM) experience poorer antiretroviral therapy (ART) medication adherence relative to their white counterparts. However, few studies have longitudinally examined factors that may correlate with various classifications of ART adherence among this population, which was the primary aim of this study. METHODS: Project nGage was a randomized controlled trial conducted across five Chicago clinics from 2012 to 2015. Survey and medical records data were collected at baseline and 3- and 12-month periods to assess whether psychological distress, HIV stigma, substance use, family acceptance, social support, and self-efficacy predicted ART medication adherence among 92 YBMSM ages 16-29 years. RESULTS: Major results controlling for the potential effects of age, education level, employment, and intervention condition indicated that participants with high versus low medication adherence were less likely to report daily/weekly alcohol or marijuana use, had higher family acceptance, and exhibited greater self-efficacy. CONCLUSIONS: These findings identity important factors that can be targeted in clinical and program interventions to help improve ART medication adherence for YBMSM.

Risk Group and Death From Prostate Cancer: Implications for Active Surveillance in Men With Favorable Intermediate-Risk Prostate Cancer.

IMPORTANCE: Active surveillance (AS), per the National Comprehensive Cancer Network (NCCN) guidelines, is considered for patients with low-risk prostate cancer (PC) and a life expectancy of at least 10 years. However, given the grade migration following the 2005 International Society of Urologic Pathology consensus conference, AS may be appropriate for men presenting with favorable intermediate-risk PC. OBJECTIVE: To estimate and compare the risk of PC-specific mortality (PCSM) and all-cause mortality (ACM) following brachytherapy among men with low and favorable intermediate-risk PC. DESIGN, SETTING, AND PARTICIPANTS: Prospective cohort study of 5580 consecutively treated men (median age, 68 years) with localized adenocarcinoma of the prostate treated with brachytherapy at the Prostate Cancer Foundation of Chicago between October 16, 1997, and May 28, 2013. INTERVENTION: Standard of practice per the NCCN guidelines. MAIN OUTCOMES AND MEASURES: Fine and Gray competing risks regression and Cox regression analyses were used to assess whether the risks of PCSM and ACM, respectively, were increased in men with favorable intermediate-risk vs low-risk PC. Analyses were adjusted for age at brachytherapy, year of treatment, and known PC prognostic factors. RESULTS: After median follow-up of 7.69 years, 605 men had died (10.84% of total cohort), 34 of PC (5.62% of total deaths). Men with favorable intermediate-risk PC did not have significantly increased risk of PCSM and ACM compared with men with low-risk PC (adjusted hazard ratio [HR], 1.64; 95% CI, 0.76-3.53; P = .21 for PCSM; adjusted HR, 1.11; 95% CI, 0.88-1.39; P = .38 for ACM). Eight-year adjusted point estimates for PCSM were low: 0.48% (95% CI, 0.23%-0.93%) and 0.33% (95% CI, 0.19%-0.56%) for men with favorable intermediate-risk PC and low-risk PC, respectively. The respective estimates for ACM were 10.45% (95% CI, 8.91%-12.12%) and 8.68% (95% CI, 7.80%-9.61%). CONCLUSIONS AND RELEVANCE: Men with low-risk PC and favorable intermediate-risk PC have similarly low estimates of PCSM and ACM during the first decade following brachytherapy. While awaiting the results of ProtecT, the randomized trial of AS vs treatment, our results provide evidence to support AS as an initial approach for men with favorable intermediate-risk PC.

Adherence to Centers for Disease Control and Prevention Gonococcal Treatment Guidelines Among Chicago Health Care Providers, 2011-2012.

BACKGROUND: Expansion of antimicrobial resistance in Neisseria gonorrhoeae requires rapid adaptation of treatment guidelines and responsive provider practice. We evaluated patient factors associated with provider adherence to the Centers for Disease Control and Prevention gonococcal treatment recommendations among Chicago providers in 2011 to 2012. METHODS: Laboratory-confirmed cases of uncomplicated urogenital gonorrhea were classified via surveillance data as originating from Chicago Department of Public Health (CDPH) or non-CDPH providers. Recommended treatment was determined according to the Centers for Disease Control and Prevention sexually transmitted disease treatment guidelines: April 2011-July 2012 (period 1) and August-December 2012 (period 2, after August 2012 revision). Multivariable log-binomial regression identified factors associated with recommended treatment over time, stratified by provider type. RESULTS: April 2011 through December 2012, 16,646 laboratory-confirmed gonorrhea cases were identified, of which 9597 (57.7%) had treatment information: 2169 CDPH cases and 7428 non-CDPH cases. Documented recommended treatment increased for CDPH (period 1: 71.3%, period 2: 80.8%; P < 0.01) and non-CDPH providers (period 1: 63.5%, period 2: 68.9%; P < 0.01). Among CDPH cases, statistically significant factors associated with recommended treatment were male sex (adjusted prevalence rate ratio [aPRR], 1.16) white versus black race (aPRR, 0.68), same-day treatment (aPRR, 1.07), and period 2 (aPRR, 1.11). Among non-CDPH cases, statistically significant factors were as follows: male sex (aPRR, 1.10), other versus black race (aPRR, 0.91), same-day treatment (aPRR, 1.31), greater number of within-facility reported cases (aPRRs ranging from 1.22 to 1.41), and at least 50% within-facility missing treatment data (aPRR, 0.84). CONCLUSIONS: Recommended treatment improved over time, yet remains suboptimal. Efforts to reduce variability and improve provider adherence to recommended treatment are urgently needed.

Assessing racial/ethnic disparities in chemotherapy treatment among breast cancer patients in context of changing treatment guidelines.

Conflicting study results with regards to racial/ethnic disparities in chemotherapy use among breast cancer patients may be due to the different sample populations, treatment data sources, and treatment eligibility definitions used. This study examined chemotherapy disparity in the context of changing treatment guidelines and explored factors that may help explain treatment differences observed. The data come from a population-based study that included interview and medical record data (including state cancer registry) from non-Hispanic (nH) White, nH Black, and Hispanic breast cancer patients diagnosed in 2005-2008. Logistic regression using model-based standardization was used to estimate age-adjusted risk differences and multivariate analysis was conducted to identify explanatory factors of the differences. Per the 2005/2006 National Comprehensive Cancer Network (NCCN) guidelines, minority patients appeared more likely than nH White patients to receive a chemotherapy recommendation (0.87 vs 0.75, p = 0.003). When eligibility was determined per the 2007 guidelines, there was no disparity because under these guidelines, nH White patients were more likely than minority patients to have tumors that no longer required chemotherapy. There was evidence that chemotherapy advances for breast cancer patients are implemented in the clinical setting well ahead of NCCN guidelines. Finally, among eligible patients, chemotherapy recommendation was very high and virtually always accepted and received, with no disparities found at these points of clinical care. The findings suggest that an evaluation of guideline-adherent chemotherapy treatment patterns must carefully consider the definition of treatment eligibility, given ongoing changes in treatment guidelines and early uptake of new diagnostic tools and treatments.

Religiosity, spirituality, and end-of-life planning: a single-site survey of medical inpatients.

CONTEXT: Prior studies suggest that terminally ill patients who use religious coping are less likely to have advance directives and more likely to opt for heroic end-of-life measures. Yet, no study to date has examined whether end-of-life practices are associated with measures of religiosity and spirituality. OBJECTIVES: To assess the relationship between general measures of patient religiosity and spirituality and patients' preferences for care at the end of life. METHODS: We examined data from the University of Chicago Hospitalist Study, which gathers sociodemographic and clinical information from all consenting general internal medicine patients at the University of Chicago Medical Center. Primary outcomes were whether the patient had an advance directive, a do-not-resuscitate (DNR) order, a durable power of attorney for health care, and an informally designated decision maker. Primary predictors were religious attendance, intrinsic religiosity, and self-rated spirituality. RESULTS: The sample population (n=8308) was predominantly African American (73%) and female (60%). In this population, 1.5% had advance directives and 10.4% had DNR orders. Half (51%) of the patients had specified a decision maker. White patients were more likely than African American patients to have an advance directive (odds ratio [OR] 2.1; 95% CI 1.1-4.0) and a DNR order (OR 1.7; 95% CI 1.0-2.9). Patients reporting high intrinsic religiosity were more likely to have specified a decision maker than those reporting low intrinsic religiosity (OR 1.3; 95% CI 1.1-1.6). The same was true for those with high compared with low spirituality (OR 1.3; 95% CI 1.1-1.5). Religious characteristics were not significantly associated with having an advance directive or DNR order. CONCLUSION: Among general medicine inpatients at an urban academic medical center, those who were highly religious and/or spiritual were more likely to have a designated decision maker to help with end-of-life decisions but did not differ from other patients in their likelihood of having an advance directive or DNR order.

Predictors of serum vitamin D levels in African American and European American men in Chicago.

Vitamin D deficiency is epidemiologically linked to prostate, breast, and colon cancer. When compared with European American (EA) men, African American (AA) men have increased risk of prostate cancer, but few studies evaluate vitamin D status in AA men. The authors evaluate the biological and environmental predictors of vitamin D deficiency in AA and EA men in Chicago, Illinois, a low ultraviolet radiation environment. Blood samples were collected from 492 men, aged between 40 and 79 years, from urology clinics at three hospitals in Chicago, along with demographic and medical information, body mass index, and skin melanin content using a portable narrow-band reflectometer. Vitamin D intake and ultraviolet radiation exposure were assessed using validated questionnaires. The results demonstrated that Black race, cold season of blood draw, elevated body mass index, and lack of vitamin D supplementation increase the risk of vitamin D deficiency. Supplementation is a high-impact, modifiable risk factor. Race and sunlight exposure should be taken into account for recommended daily allowances for vitamin D intake.

Determinants of circulating 25-hydroxyvitamin D and bone mineral density in young physicians.

OBJECTIVE: To examine determinants of serum 25-hydroxyvitamin D [25(OH)D] and bone mineral density (BMD) in young physicians, a group not well studied previously. METHODS: We analyzed data from a questionnaire completed by young physicians as well as results of serum 25(OH)D, serum parathyroid hormone, and BMD measurements. RESULTS: Among 104 study subjects, 42% were white, 46% were Asian, 12% were "other" (10 Hispanic and 2 African American subjects), and 75% were women. The mean age and body mass index (BMI) were 28.1 years and 23.0 kg/m², respectively. White subjects had a higher mean serum 25(OH)D level (27.3 ng/mL) than did Asian subjects (15.9 ng/mL) and other subjects (22.3 ng/mL) (P<.0001). White subjects tended to have higher Z-scores than Asian subjects and other subjects for the hip (P = .06), trochanter (P = .08), and lumbar spine (P = .08). The serum 25(OH)D level was negatively associated with serum parathyroid hormone (r = -0.44; P<.01) but not with BMD. The prevalence of vitamin D insufficiency [serum 25(OH)D <30 ng/mL, 77% for the entire group] was higher (P<.01) in Asian subjects (93%) than in white subjects (61%) and other subjects (73%). Significant determinants of serum 25(OH)D included age, ethnicity, exposure to sunlight, use of vitamin D supplements, and family history of osteoporosis (P<.05 for all), and together with sex, calcium supplements, exercise, and BMI, these factors explained 49% of serum 25(OH)D level variability. Significant determinants of low BMD (osteopenia plus osteoporosis, prevalence 37.5%) included sex (P = .002) and BMI (P<.0001) but not serum 25(OH)D; Asian ethnicity reached borderline significance (P = .088). Age, sex, ethnicity, smoking, and BMI explained 20% to 30% of the Z-score variations. CONCLUSION: In young physicians with a healthful lifestyle, determinants of low serum 25(OH)D and BMD included modifiable risk factors. Vitamin D insufficiency and low BMD could be important contributors to future osteoporotic fractures in this population.

Correlates of vitamin D insufficiency in an affluent adult population.

OBJECTIVES: Vitamin D is necessary for bone health and calcium metabolism. Vitamin D deficiency may play a role in coronary artery disease, some cancers, autoimmune disease, and glucose tolerance. Vitamin D deficiency may be prevalent even among affluent US adults. METHODS: We conducted a retrospective chart review study of 287 adult patients who underwent executive physical examinations between April 2009 and May 2010 in Chicago, Illinois. Data collected included age, sex, body mass index, vitamin D levels, supplement use, fish consumption, milk consumption, hours spent outdoors, and sunscreen use. Vitamin D insufficiency was defined as <30 ng/mL. RESULTS: The mean vitamin D level was 40.0 ng/mL (standard deviation 16.6), which varied by month. The mean vitamin D level ranged from 32.9 ng/mL in January to 55.4 ng/mL in September. Insufficient levels of vitamin D were observed in 30.3% of patients. Younger age (younger than 40 years); no milk or fish consumption; no use of multivitamins, vitamin D supplements, or calcium supplements; no sun exposure; and routine use of sunscreens were positively associated with vitamin D insufficiency. CONCLUSION: Vitamin D insufficiency in almost one-third of patients presenting for executive physicals may be indicative of a widespread nutritional deficiency in the US population.

The impact of thalassemia on Southeast Asian and Asian Indian families in the United States: a qualitative study.

OBJECTIVE: To describe the challenges, including sociocultural and socioeconomic barriers, faced by an urban immigrant population in the United States affected by thalassemia major. DESIGN: Ethnographic, semi-structured, 1-on-1 interviews using an interview guide developed for this study. Digital recordings were transcribed and data analyzed using constant comparative method. SETTING: University-based, Comprehensive Thalassemia Program at Children's Memorial Hospital, Chicago, IL, USA. PARTICIPANTS: Fourteen Southeast Asian and Asian Indian parents of children with transfusion dependent thalassemia. MAIN OUTCOME MEASURE: Qualitative descriptions of parental experiences, frequency of codes applied to interviews and emergent themes. RESULTS: Thalassemia has its greatest impact on the emotional and social well-being of affected children and their parents. Current and future concerns were related to disease-specific complications and challenges with management such as transfusions and chelation therapy. These perceptions were tied to parental hope for a cure, a frequently coded coping mechanism. Despite their availability, few parents relied on support systems beyond immediate family members due to perceived public knowledge gaps about thalassemia. Culturally based past experiences and barriers did not emerge as dominant themes in our analysis. CONCLUSION: The impact of thalassemia is tremendous for affected children and their parents and is due more to factors that were either disease-specific or common to other chronic disease models rather than those influenced by culture. The unmet needs of these families require additional investigation to facilitate the development of initiatives aimed at improving quality of life and lessening overall impact of thalassemia

Explanatory models of health and disease among South Asian immigrants in Chicago.

To identify concepts of health and disease as part of a study on designing culturally-targeted heart disease prevention messages for South Asians. We conducted qualitative, semi-structured interviews in English, Hindi and Urdu with 75 respondents from a federally qualified health center and at a community center for South Asian immigrants in Chicago, Illinois. Age ranged from 20 to 70 years; 60% were women; 60% held advanced degrees; 70% migrated to the US in the last 10 years; and 60% of the interviews were in Hindi or Urdu. Concepts of health and disease fell into four domains: behavioral, physical, psycho-social and spiritual. Muslim participants consistently evoked spiritual factors such as faith and prayer. Women more frequently included performing home duties and positive affect in their concept of health. Men more frequently cited behavioral factors such as smoking and drinking as the cause of disease. Many South Asians have a holistic conceptualization of health and disease, incorporating spiritual, physical and psycho-social factors. Health promotion strategies aimed at South Asians in the US should take into account this holistic model of health and disease, while also recognizing that variations exist within South Asians, by gender and religion.

Prevalence of 25-hydroxyvitamin D deficiency in the outpatient rehabilitation population.

OBJECTIVE: To assess the prevalence of 25-hydroxyvitamin D insufficiency and deficiency in the outpatient rehabilitation setting and to identify patient characteristics associated with low serum 25-hydroxyvitamin D levels. DESIGN: 25-Hydroxyvitamin D levels from 136 rehabilitation outpatients at an academic rehabilitation facility obtained from April 2007 to December 2008 for patient care purposes were captured via retrospective electronic medical record review. RESULTS: Considering only those subjects not receiving 25-hydroxyvitamin D supplementation at time of evaluation, 33.0% were 25-hydroxyvitamin D Sufficient while 53.2% were Insufficient and 13.8% Deficient. Those outpatient subjects receiving supplementation at time of evaluation had significantly higher 25-hydroxyvitamin D levels compared with those not receiving supplementation (34.1 ± 14.2 ng/ml vs. 25.9 ± 15.2 ng/ml; P = 0.005). Blacks had significantly lower 25-hydroxyvitamin D levels compared with whites (18.0 ± 10.6 ng/ml vs. 31.3 ± 14.3 ng/ml; P < 0.001). Subjects not on vitamin D supplementation assigned to diagnostic groups, Spinal Cord Injury, Brain Injury, and Hereditary Musculoskeletal, all had average 25-hydroxyvitamin D levels well below the lower limit of Sufficiency. CONCLUSIONS: Sixty-seven percent of rehabilitation outpatients are 25-hydroxyvitamin D Insufficient or Deficient. Supplementation significantly affects 25-hydroxyvitamin D levels in the outpatient rehabilitation population. Non-white race and history of Spinal Cord Injury, Brain Injury, or Hereditary Musculoskeletal diagnosis seem to be associated with lower 25-hydroxyvitamin D levels.

Determinants of 25-hydroxyvitamin D levels in African-American and Caucasian male veterans.

SUMMARY: Among 307 males seen in VA Medical Center, independent determinants (p < 0.01 for all) of serum 25-hydroxyvitamin D [25(OH)D] levels included race, vitamin D supplements, BMI, dietary calcium intake and smoking, but not age. Negative association between 25(OH)D and parathyroid hormone (PTH) was similar for Caucasian and African-American men. INTRODUCTION: In this prospective cohort study, we examined determinants of serum 25-hydroxyvitamin D [25(OH)D] levels and the relationship between 25(OH)D and PTH levels and body mass index (BMI). METHODS: Male veterans (n = 307) were recruited at a VA Medical Center. Serum levels of PTH and 25(OH)D were obtained. Surveys and chart reviews were completed. Vitamin D insufficiency was defined as 25(OH)D <30 ng/ml. Univariate and multivariate regression analyses were performed. RESULTS: Among 232 African-American (AA) men (mean +/- SD), 25(OH)D level (21.4 +/- 10.4 ng/ml) was lower and prevalence of insufficiency (80%) was higher than among 75 Caucasians (C; 28.5 +/- 11.1 ng/ml and 53%, respectively, p < 0.01 for both). In multivariate regression analysis, independent determinants (p < 0.01 for all) of 25(OH)D levels included AA race, vitamin D supplements, BMI, dietary calcium intake, and smoking. Despite lower 25(OH)D levels in African-Americans, PTH levels were similar to those seen in Caucasians. There was a significant (p < 0.02) negative linear association between 25(OH)D and PTH in African-American (r(2) = 0.05) and Caucasian (r(2) = 0.08) men, and there was no difference between the slopes of the relationship. CONCLUSIONS: 25(OH)D levels are determined by modifiable risk factors such as vitamin D supplementation in both AA and C males. The negative association between 25(OH)D and PTH is similar between the two races.

Substance-related problems and treatment among men who have sex with men in comparison to other men in Chicago.

This study compares a sample of urban men who have sex with men (MSM) with a general population sample of men in the same city on self-reported problems with substance use indicative of dependence and history of substance use treatment. Both samples were randomly selected using multistage probability methods. All participants completed audio computer-assisted self-interviews, including questions on substance use, problems related to substance use experienced in the past 12 months, and substance treatment. Problem use of alcohol, marijuana, and cocaine did not differ between samples. Compared to men in the general population sample, MSM were significantly more likely to experience problems related to the use of sedatives, tranquilizers, or prescription pain relievers. Among MSM, history of substance treatment was associated with a positive HIV test, and treatment usually preceded HIV diagnosis. Research is needed on effective methods for integrating HIV prevention for MSM into substance treatment settings, including physician-administered buprenorphine treatment for opiate addiction.

An examination of the relationship between multiple dimensions of religiosity, blood pressure, and hypertension.

Researchers have established the role of heredity and lifestyle in the occurrence of hypertension, but the potential role of psychosocial factors, especially religiosity, is less understood. This paper analyzes the relationship between multiple dimensions of religiosity and systolic blood pressure, diastolic blood pressure, and hypertension using data taken from the Chicago Community Adult Health Study, a probability sample of adults (N=3105) aged 18 and over living in the city of Chicago, USA. Of the primary religiosity variables examined here, attendance and public participation were not significantly related to the outcomes. Prayer was associated with an increased likelihood of hypertension, and spirituality was associated with increased diastolic blood pressure. The addition of several other religiosity variables to the models did not appear to affect these findings. However, variables for meaning and forgiveness were associated with lower diastolic blood pressure and a decreased likelihood of hypertension outcomes. These findings emphasize the importance of analyzing religiosity as a multidimensional phenomenon. This study should be regarded as a first step toward systematically analyzing a complex relationship.
