Treatment Dosing Patterns and Clinical Outcomes for Patients with Type 2 Diabetes Starting or Switching to Treatment with Insulin Glargine (300 Units per Milliliter) in a Real-World Setting: A Retrospective Observational Study.

INTRODUCTION: Usage patterns and effectiveness of a longer-acting formulation of insulin glargine at a strength of 300 units per milliliter (Gla-300) have not been studied in real-world clinical practice. This study evaluated differences in dosing and clinical outcomes before and after Gla-300 treatment initiation in patients with type 2 diabetes starting or switching to treatment with Gla-300 to assess whether the benefits observed in clinical trials translate into real-world settings. METHODS: This was a retrospective observational study using medical record data obtained by physician survey for patients starting treatment with insulin glargine at a strength of 100 units per milliliter (Gla-100) or Gla-300, or switching to treatment with Gla-300 from treatment with another basal insulin (BI). Differences in dosing and clinical outcomes before versus after treatment initiation or switching were examined by generalized linear mixed-effects models. RESULTS: Among insulin-naive patients starting BI treatment, no difference in the final titrated dose was observed in patients starting Gla-300 treatment versus those starting Gla-100 treatment [least-squares (LS) mean 0.43 units per kilogram vs 0.44 units per kilogram; P = 0.77]. Both groups had significant hemoglobin A1c level reductions (LS mean 1.21 percentage points for Gla-300 and 1.12 percentage points for Gla-100 ; both P < 0.001). The relative risk of hypoglycemic events after Gla-300 treatment initiation was lower than that after Gla-100 treatment initiation [0.31, 95% confidence interval (CI) 0.12-0.81; P = 0.018] at similar daily doses. The daily dose of BI was significantly lower after switching to treatment with Gla-300 from treatment with another BI (0.73 units per kilogram before switch vs 0.58 units per kilogram after switch; P = 0.02). The mean hemoglobin A1c level was significantly lower after switching than before switching (adjusted difference - 0.95 percentage points, 95% CI - 1.13 to - 0.78 percentage points ; P < 0.0001). Hypoglycemic events per patient-year were significantly lower (relative risk 0.17, 95% CI 0.11-0.26; P < 0.0001). CONCLUSIONS: Insulin-naive patients starting Gla-300 treatment had fewer hypoglycemic events, a similar hemoglobin A1c level reduction, and no difference in insulin dose versus patients starting Gla-100 treatment. Patients switching to Gla-300 treatment from treatment with other BIs had significantly lower daily doses of BI, with fewer hypoglycemic events, without compromise of hemoglobin A1c level reduction. These findings suggest Gla-300 in a real-world setting provides benefits in terms of dosing, with improved hemoglobin A1c level and hypoglycemia rates. FUNDING: Sanofi US Inc.

Impact of delaying treatment intensification with a glucagon-like peptide-1 receptor agonist in patients with type 2 diabetes uncontrolled on basal insulin: A longitudinal study of a US administrative claims database.

AIM: To evaluate the effect of delaying treatment intensification with a glucagon-like peptide-1 receptor agonist (GLP-1 RA) on clinical and economic outcomes in patients with type 2 diabetes (T2D). METHODS: We conducted a retrospective observational claims study using IMPACT (Impact National Managed Care Benchmark Database) in adult patients with T2D who initiated basal insulin between January 1, 2005 and December 31, 2012, with or without OADs, who remained uncontrolled (glycated haemoglobin [HbA1c] ≥7.0%). Patients were categorized into 3 groups: early, delayed, and no intensification with a GLP-1 RA. We evaluated changes from baseline to follow-up at 12 months for HbA1c level, rate of hypoglycaemic events, and healthcare costs, and we assessed the association between baseline patient characteristics and subsequent treatment intensification. RESULTS: A total of 139 patients (9.0% of 1552 eligible patients) met criteria for inclusion in the early intensification group, 588 patients (37.9%) met criteria for inclusion in the delayed intensification group, and 825 patients (53.2%) met criteria for inclusion in the no intensification group. Mean baseline HbA1c values were 9.16%, 9.07%, and 9.34%, respectively. At follow-up, delayed intensification was associated with significantly smaller decreases in HbA1c from baseline (-0.68%) compared with early intensification (-1.01%). Rates of overall hypoglycaemia were numerically greater in the delayed intensification group than in the early intensification group (0.26 vs 0.06 events/patient-years of exposure, respectively). Change in semi-annual total healthcare costs was greater in the no intensification group (+5266 USD) compared with the early intensification group (-560 USD) and the delayed intensification group (+1943 USD). CONCLUSIONS: Timely addition of a GLP-1 RA to therapy for patients with T2D who were not adequately controlled with basal insulin is associated with better clinical and economic outcomes.

Glycaemic control and hypoglycaemia burden in patients with type 2 diabetes initiating basal insulin in Europe and the USA.

AIMS: To evaluate short- and long-term glycaemic control and hypoglycaemia incidence in insulin-naïve patients ≥30 years of age with type 2 diabetes (T2DM) initiating basal insulin (BI) with or without oral anti-hyperglycaemic drugs (OADs). METHODS: This was an observational, retrospective longitudinal analysis of electronic medical records from 5 European countries and the USA. A multivariable logistic regression model assessed baseline and short-term (0-3 months post BI initiation) factors associated with long-term (3-24 months) glycaemic control and hypoglycaemia. RESULTS: Overall, 40 627 patients were included; 20.9% and 27.8% achieved the general HbA1c target of ≤7% at 3 and 24 months post BI initiation, respectively. Failure to achieve HbA1c ≤7% at 3 months was associated with increased risk of failing to achieve target at 24 months (odds ratio [OR], 3.70 [95% CI, 3.41-4.00]). Over 24 months, 8.9% of patients experienced a recorded hypoglycaemic event. Hypoglycaemia during the initial 3-month period was associated with longer-term risk of these events over the ensuing 3 to 24 months (OR, 5.71 [95% CI, 4.67-6.99]). CONCLUSIONS: Initiating BI with or without OADs is associated with short- and long-term suboptimal glycaemic control; the majority of patients fail to achieve HbA1c target ≤7% in the first 3 months, or after 2 years of BI treatment. Treatment response and hypoglycaemia incidence by 3 months post BI initiation are associated with longer-term glycaemic control and hypoglycaemic risk, respectively. These results support the need for early anti-hyperglycaemic interventions that more effectively control blood glucose levels without increasing the risk of hypoglycaemia.

Effect of Diabetes Treatment-Related Attributes on Costs to Type 2 Diabetes Patients in a Real-World Population.

BACKGROUND: Type 2 diabetes mellitus (T2DM) results in a substantial economic burden on patients, health care systems, and society. Most literature assessing the cost of T2DM focuses on the long-term complications of the disease, the association between glucose control and cost, and patient characteristics resulting in poor and costly outcomes. However, it is likely that attributes specific to diabetes therapy can affect the use of costly resources. OBJECTIVE: To estimate the effect of diabetes treatment-related attributes, such as improved efficacy, adherence, and reduced risk for hypoglycemia, on costs to T2DM patients. METHODS: An observational, retrospective study was conducted using the Optum Clinformatics Database, which links medical and pharmacy claims to laboratory results. Patients aged ≥ 18 years with T2DM who had ≥ 1 antidiabetic medication claim; ≥ 1 hemoglobin A1c (A1c) test result; continuous enrollment in the health plan from April 1, 2010, to March 31, 2011; and at least 1 follow-up day were included. Nondiabetes specific total, inpatient, outpatient, emergency room, and other costs (along with antidiabetes medication costs) were defined for each patient. Generalized linear models with logarithm link were used to predict the 1-year and cumulative 3-year costs. Demographic factors and comorbidities were included as covariates in addition to the diabetes treatment-related attributes. RESULTS: In the entire analysis cohort, the average 3-year cost per patient was $74,862. The percentage effect on cost of diabetes treatment-related variables ranged from -18% to 429%. Drug adherence was associated with lower inpatient, outpatient, and emergency room costs and higher drug costs. Hypoglycemia was associated with higher inpatient, outpatient, emergency room, and other direct costs (except antidiabetic drug costs). Compared with A1c values ≤ 7%, patients with higher levels were associated with higher total and drug costs. CONCLUSIONS: Study results demonstrate the association between diabetes treatment-related attributes and costs, including inpatient, outpatient, drug, and total costs. This association raises the question: what would the effect of a new diabetes therapy, with high efficacy, high adherence, and reduced risk of hypoglycemia have on economic outcomes?

Post-polypectomy Guideline Adherence: Importance of Belief in Guidelines, Not Guideline Knowledge or Fear of Missed Cancer.

BACKGROUND: Adherence to post-polypectomy surveillance guideline recommendations is suboptimal. Surveillance is frequently over- and under-recommend, resulting in strained colonoscopy capacity, potential risks without expected benefits, and missed opportunities for colorectal cancer risk reduction. AIMS: To identify factors associated with adherence to post-polypectomy surveillance guidelines. METHODS: We conducted a three-phase study with a retrospective review of usual care post-polypectomy surveillance recommendations through medical chart abstraction (Phase I), prospective online physician survey (Phase II), and analysis of survey-based and other physician-based predictors of usual care surveillance recommendations (Phase III). Subjects included patients who underwent usual care colonoscopy 2011-2012 (Phases I and III) and gastroenterology (GI) attendings and fellows (Phases II and III). We identified rates of recommendations consistent with guideline adherence, surveillance overuse, and surveillance underuse based on usual care medical chart documentation and physician survey, as well as predictors of physician adherence to guidelines. RESULTS: We reviewed 640 patient charts for 28 survey respondents. Rates of usual practice recommendations consistent with guideline adherence, surveillance overutilization, and underutilization were 84, 13, and 3%, respectively. At survey, 82% of physicians were concerned about missed cancer. Eleven percentage believed that guidelines were not aggressive enough. GI trainees were 2.5 times more likely to issue guideline-adherent recommendations [OR 2.5, 95% CI (1.5-4.2)]. Disagreement with guideline aggressiveness was independently associated with 40% lower likelihood of adherence [OR 0.6, 95% CI (0.4-0.8)]. CONCLUSIONS: Belief in the appropriate aggressiveness of guidelines and trainee position, but not fear of missed cancer or guideline knowledge, was associated with adherence to post-polypectomy surveillance guidelines.

Relative impact of earlier diagnosis and improved treatment on survival for colorectal cancer: a US database study among elderly.

PURPOSES: To estimate what proportion of improvement in relative survival was attributable to smaller stage/size due to early detection and what proportion was attributable to cancer chemotherapy in patients with colorectal cancer (CRC). METHODS: We studied 69,718 patients with CRC aged ≥ 66 years in 1992-2009 from Surveillance, Epidemiology, and End Results registries. Study periods were categorized into three periods according to the major changes or advances in screening and chemotherapy regimens: (1) Period-1 (1992-1995), during which there was no evidence-based recommendation for routine CRC screening and 5-fluorouracil was the mainstay for chemotherapy; (2) Period-2 (1996-2000), during which evidences and guidelines supported the use of fecal occult blood test (FOBT) and sigmoidoscopy for routine CRC screening; and (3) Period-3 (2001-2009), during which Medicare Program added the full coverage for colonoscopy screening to average-risk individuals, and several newly developed chemotherapy regimens were approved. Outcome variables included the likelihood of being diagnosed at an early stage or with a small tumor size, and improvement in relative survival. RESULTS: Compared to period-1, likelihood of being diagnosed with early stage CRC increased by 20% in period-2 (odds ratio = 1.2, 95%CI: 1.1-1.2) and 30% in period-3 (1.3, 1.2-1.4); and likelihood of being diagnosed with small-size CRC increased by 60% in period-2 and 110% in period-3. Similarly, 5-year overall relative survival increased from 51% in period-1 to 56% in period-2 and 60% in period-3. Increase in survival attributable to migration in stage/size was 9% in period-2 and 20% in period-3, while the remaining survival improvement during period-2 and period-3 were largely attributable to more effective chemotherapy regimens (≥ 71.6%) and other treatment factors (≤ 25%). CONCLUSIONS: Improvements in CRC screening resulted in a migration of CRC toward earlier tumor stage and smaller size, which contributed to ≤ 20% of survival increase. Survival improvement over the past 2 decades was largely explained by more effective chemotherapy regimens (≥ 71.6%).

Temporal trends in the leading causes of death among a large national cohort of patients with colorectal cancer from 1975 to 2009 in the United States.

PURPOSE: To assess the distribution of proportion of deaths from causes other than colorectal cancer (CRC) over time and temporal trends of cause-specific cumulative incidence of death due to six leading causes in patients with CRC. METHODS: Overall, 375,462 patients with CRC in nine Surveillance, Epidemiology, and End Results registries from 1975 to 2009 were included. Competing risks proportional hazards regression was used to examine the effect of diagnostic periods on the risk of cause-specific death. RESULTS: From 1975 to 2009 by 5-year interval, the proportion of deaths from causes other than CRC increased significantly with diagnostic periods according to the lengths of follow-up (P < .0001). The 5-year risk of death significantly decreased with diagnostic periods for all-cause, CRC, and circulation diseases among all age groups (<65, 65-74, and ≥75 years) but increased for chronic obstructive pulmonary disease, diabetes, and Alzheimer disease among patients aged 65 years or older. CONCLUSIONS: Deaths due to causes other than CRC increased significantly over time regardless of tumor stage and site but more sharply in those with early-stage and distal colon cancer. The increasing leading causes of death are chronic obstructive pulmonary disease, diabetes, and Alzheimer disease, which may be prevented or delayed substantially by modification or intervention in lifestyle or other factors.

Blood pressure abnormalities in children with sickle cell anemia.

BACKGROUND: Kidney disease is an important cause of morbidity and mortality in patients with sickle cell anemia (SCA). The factors that affect progression of renal disease are unknown, especially in children and adolescents. Alterations in blood pressure, including hypertension and lack of the normal nocturnal dip in blood pressure, are important determinants of diabetic nephropathy and other renal diseases and may play a role in sickle cell nephropathy. Our primary hypothesis was that children with SCA who have microalbuminuria will demonstrate less nocturnal dipping of blood pressure compared to patients without microalbuminuria. We also investigated other potential factors associated with microalbuminuria. PROCEDURE: This prospective study of 52 adolescents with SCA followed in the Children's Medical Center Dallas Comprehensive Sickle Cell Center characterized 24-hour ambulatory blood pressure profiles and presence of microalbuminuria. Stepwise logistic regression was performed to identify significant independent factors that are associated with microalbuminuria. RESULTS: Thirty-five percent of patients were identified as having previously unrecognized hypertension, and 17% had pre-hypertension (blood pressure greater than the 90th percentile but less than the 95th percentile). Fifty-six percent of patients lacked the normal nocturnal dip in blood pressure. In addition, 21% had microalbuminuria, and their percent nocturnal dip was significantly less than those without microalbuminuria (P = 0.01). CONCLUSIONS: Blood pressure abnormalities are common in adolescents with SCA and are a possible modifiable risk factor in the progression of sickle cell nephropathy.

Analysis of comorbidities and objective parameters in refractory chronic rhinosinusitis.

OBJECTIVES/HYPOTHESIS: The objective of this study was to construct the clinical profile of patients with chronic rhinosinusitis (CRS) with/without polyposis undergoing revision sinus surgery and to evaluate the relationship of polyposis, asthma, acetylsalicylic acid (aspirin) (ASA) sensitivity, inhalant allergies, and previous sinus surgery on disease severity as measured by objective parameters. STUDY DESIGN: Cross-sectional study. METHODS: Two-hundred twenty-five patients were accrued at a tertiary care academic center. Categorical factors recorded included presence of polyps, asthma, inhalant allergy, and ASA sensitivity. Continuous variables assessed included mean number of previous sinus surgeries, Lund-Kennedy endoscopy score, Lund-Mackay computed tomography (CT) score, absolute eosinophil count (AEC), and total immunoglobulin E (tIgE) level. Statistical analysis was performed to analyze the impact of polyposis, asthma, inhalant allergy, and ASA sensitivity on objective parameters. The mean number of previous surgeries was also correlated with objective parameters. RESULTS: The mean age was 50.1 years with a male:female ratio of 1.1:1. The overall prevalence of polyposis, asthma, inhalant allergy, and ASA sensitivity was 56.4%, 48.4%, 38.7%, and 16.0%, respectively. The mean endoscopy and CT scores were 9.0 (± 4.0) and 11.4 (± 5.8), respectively. The mean AEC and tIgE were 0.4 k/µL (± 0.4) and 161.4 IU/mL (± 251.4). The mean number of previous endoscopic sinus surgeries was 1.8. Patients with CRS with polyposis had a statistically significant increase in presence of asthma (odds ratio [OR]: 7.5, P < .0001), inhalant allergy (OR: 3.6, P < .0001), and ASA sensitivity (OR: 78.6, P < .0001). Patients with polyposis had a statistically significant increase in endoscopy score (P < .0001), CT score (P < .0001), AEC (P < .0001), and tIgE (P = .0002). Patients with asthma had a statistically significant increase in endoscopy (P < .0001) and CT scores (P < .0001), AEC (P < .0001), and tIgE (P = .0002). Patients with inhalant allergy had a statistically significant increase in endoscopy (P = .0069), CT scores (P = .0017), and tIgE (P = .0084) but not AEC (P = .1492). Patients with ASA sensitivity had a statistically significant increase in endoscopy score (P < .0001), CT score (P < .0001), and AEC (P = .003) but not tIgE level (P = .186). The number of previous surgeries had a statistically significant correlation with endoscopy (P = .006) and CT scores (P = .03) but not AEC (P = .48) or tIgE (P = .66). CONCLUSIONS: The current analysis constructed the clinical profile of the recalcitrant CRS patient undergoing revision sinus surgery. In general, this patient group has a high prevalence of polyposis, asthma, inhalant allergy, ASA sensitivity, and elevated disease burden as measured by objective measures. The polyp phenotype signifies statistically higher prevalence of associated comorbidities and greater objective disease severity. The presence of asthma, inhalant allergy, and ASA sensitivity also predicts statistically higher disease burden. The endoscopy and CT scores statistically correlate with the number of previous surgeries. LEVEL OF EVIDENCE: 4 Laryngoscope, 123:E1-E11, 2013.

Effect of dental education on Peruvian dental students' oral health-related attitudes and behavior.

This study evaluated the effect of dental education on oral health-related attitudes and behavior of students in a five-year dental program in Peru. A survey using the Hiroshima University-Dental Behavioral Inventory (HU-DBI), which consists of twenty dichotomous responses (agree-disagree) regarding oral health behavior and attitudes, was completed by Year 1 and Year 5 dental students at the Universidad Inca Garcilaso de la Vega in Lima, Peru. A total of 153 Year 1 students and 120 Year 5 students responded to the Spanish version of the HU-DBI questionnaire. The data were analyzed using chi-square tests and logistic regression analyses. Compared to the Year 1 students, the Year 5 dental students were more likely to agree with questions such as "I think I can clean my teeth well without using toothpaste" (OR=0.24, 95% CI: 0.10-0.58); "I have used a dye to see how clean my teeth are" (OR=0.19, 95% CI: 0.10-0.36); and "I have had my dentist tell me that I brush very well" (OR=0.34, 95% CI: 0.17-0.69). Overall, the data showed that the curriculum in this dental school in Peru resulted in more positive oral health-related attitudes and behavior among Year 5 dental students compared to those of Year 1 dental students.

Is timing to delivery of treatment a reliable measure of quality of care for patients with colorectal adenocarcinoma?

BACKGROUND: Among patients with colorectal adenocarcinoma, patient race has been associated with differences in colorectal cancer survival. Survival disparities between ethnic groups may be related to treatment delays, treating hospital, or other patient factors. We hypothesized that prolonged interval to delivery of cancer therapy negatively impacts survival. STUDY DESIGN: We designed a retrospective cohort study using tumor registry and clinical database information from two academically affiliated hospitals. We examined factors associated with interval to treatment and associations between interval and overall survival. RESULTS: Among 592 patients treated by a cohort of physicians, we found no differences in cancer stage related to race or treating hospital. Interval to treatment differed between different hospitals (29 vs. 16 days; P < .0001); yet, there were no differences in overall survival related to treatment interval, treating hospital, race, or insurance status. Tumor grade and tumor stage were associated with decreased overall survival. CONCLUSION: Differences exist related to the timing of definitive care for patients in this series; however, these differences do not translate directly into differences in overall survival. We must deliver quality health care in an efficient and timely manner; however, the metric of interval to treatment may not measure reliably the quality of care received.

Comparative effectiveness of fecal immunochemical test outreach, colonoscopy outreach, and usual care for boosting colorectal cancer screening among the underserved: a randomized clinical trial.

IMPORTANCE: Colorectal cancer (CRC) screening saves lives, but participation rates are low among underserved populations. Knowledge on effective approaches for screening the underserved, including best test type to offer, is limited. OBJECTIVE: To determine (1) if organized mailed outreach boosts CRC screening compared with usual care and (2) if FIT is superior to colonoscopy outreach for CRC screening participation in an underserved population. DESIGN, SETTING, AND PARTICIPANTS: We identified uninsured patients, not up to date with CRC screening, age 54 to 64 years, served by the John Peter Smith Health Network, Fort Worth and Tarrant County, Texas, a safety net health system. INTERVENTIONS: Patients were assigned randomly to 1 of 3 groups. One group was assigned to fecal immunochemical test (FIT) outreach, consisting of mailed invitation to use and return an enclosed no-cost FIT (n = 1593). A second was assigned to colonoscopy outreach, consisting of mailed invitation to schedule a no-cost colonoscopy (n = 479). The third group was assigned to usual care, consisting of opportunistic primary care visit­based screening (n = 3898). In addition, FIT and colonoscopy outreach groups received telephone follow-up to promote test completion. MAIN OUTCOME MEASURES: Screening participation in any CRC test within 1 year after randomization. RESULTS: Mean patient age was 59 years; 64% of patients were women. The sample was 41% white, 24% black, 29% Hispanic, and 7% other race/ethnicity. Screening participation was significantly higher for both FIT (40.7%) and colonoscopy outreach (24.6%) than for usual care (12.1%) (P < .001 for both comparisons with usual care). Screening was significantly higher for FIT than for colonoscopy outreach (P < .001). In stratified analyses, screening was higher for FIT and colonoscopy outreach than for usual care, and higher for FIT than for colonoscopy outreach among whites, blacks, and Hispanics (P < .005 for all comparisons). Rates of CRC identification and advanced adenoma detection were 0.4% and 0.8% for FIT outreach, 0.4% and 1.3% for colonoscopy outreach, and 0.2% and 0.4% for usual care, respectively (P < .05 for colonoscopy vs usual care advanced adenoma comparison; P > .05 for all other comparisons). Eleven of 60 patients with abnormal FIT results did not complete colonoscopy. CONCLUSIONS AND REVELANCE: Among underserved patients whose CRC screening was not up to date, mailed outreach invitations resulted in markedly higher CRC screening compared with usual care. Outreach was more effective with FIT than with colonoscopy invitation. TRIAL REGISTRATION: clinicaltrials.gov Identifier: NCT01191411.

A comparative study of oral health attitudes and behavior using the Hiroshima University-Dental Behavioral Inventory (HU-DBI) between dental and civil engineering students in Colombia.

The aim of this study was to use the Hiroshima University - Dental Behavioral Inventory (HU-DBI) to compare oral health attitudes and behavior of dental and civil engineering students in Colombia. The HU-DBI's survey consisting of twenty dichotomous responses (agree-disagree) regarding tooth brushing, was completed at University Antonio Narino for the dental students and the University of Cauca for the civil engineering students. The Spanish version of the HU-DBI questionnaire was taken by 182 of 247 dental students and 411 of 762 engineering students. The data was-statistically analyzed by the chi-square test and backward logistic regression. Compared to the engineering students, the dental students were more likely to agree with questions such as "I am bothered by the color of my gums"(OR = 2.2, 95% CI: 1.3-3.7),"I think I can clean my teeth well without using toothpaste" (OR = 3.0, 95% CI: 1.5-5.9), "I have used a dye to see how clean my teeth are" (OR = 2.9, 95% CI: 1.9-4.3), and "I have had my dentist tell me that I brush very well" (OR = 2.0, 95% CI: 1.3-3.1). The dental education curriculum in a dental school compared to a civil engineering school in Colombia indicated that a three-phase curriculum in didactics and clinics increased oral health attitudes and behavior from entry to graduation.

Churches as targets for cardiovascular disease prevention: comparison of genes, nutrition, exercise, wellness and spiritual growth (GoodNEWS) and Dallas County populations.

BACKGROUND: We compared cardiovascular (CV) risk factors (CVRFs) of community-based participatory research (CBPR) participants with the community population to better understand how CBPR participants relate to the population as a whole. METHODS: GoodNEWS participants in 20 African-American churches in Dallas, Texas were compared with age/sex-matched African-Americans in the Dallas Heart Study (DHS), a probability-based sample of Dallas County residents. DHS characteristics were sample-weight adjusted to represent the Dallas County population. RESULTS: Despite having more education (college education: 75 versus 51%, P< 0.0001), GoodNEWS participants were more obese (mean body mass index: 34 versus 31 kg/m(2), P< 0.001) and had more diabetes (23 versus 12%, P< 0.001) and hyperlipidemia (53 versus 14%, P< 0.001) compared with African-Americans in Dallas County. GoodNEWS participants had higher rates of treatment and control of most CVRFs (treated hyperlipidemia: 95 versus 64%, P< 0.001; controlled diabetes: 95 versus 21%, P< 0.001; controlled hypertension: 70 versus 52%, P= 0.003), were more physically active (233 versus 177 metabolic equivalent units-min/week, P< 0.0001) and less likely to smoke (10 versus 30%, P< 0.001). CONCLUSIONS: Compared with African-Americans in Dallas County, CBPR participants in church congregations were more educated, physically active and had more treatment and control of most CVRFs. Surprisingly, this motivated population had a greater obesity burden, identifying them as a prime target for CBPR-focused obesity treatment.

Measurement of colorectal cancer test use with medical claims data in a safety-net health system.

BACKGROUND: Optimizing colorectal cancer (CRC) screening requires identification of unscreened individuals and tracking screening trends. A recent National Institutes of Health State of the Science Conference, "Enhancing Use and Quality of CRC Screening," cited a need for more population data sources for measurement of CRC screening, particularly for the medically underserved. Medical claims data (claims data) are created and maintained by many health systems to facilitate billing for services rendered and may be an efficient resource for identifying unscreened individuals. The aim of this study, conducted at a safety-net health system, was to determine whether CRC test use measured by claims data matches medical chart documentation. METHODS: The authors randomly selected 400 patients from a universe of 20,000 patients previously included in an analysis of CRC test use based on claims data 2002-2006 in Tarrant Co, TX. Claims data were compared with medical chart documentation by estimation of agreement and examination of test use over/underdocumentation. RESULTS: The authors found that agreement on test use was very good for fecal occult blood testing (κ = 0.83, 95% confidence interval: 0.75-0.90) and colonoscopy (κ = 0.91, 95% confidence interval: 0.85-0.96) and fair for sigmoidoscopy (κ = 0.39, 95% confidence interval: 0.28-0.49). Over- and underdocumentations of the 2 most commonly used CRC tests--colonoscopy and fecal occult blood testing--were rare. CONCLUSIONS: Use of claims data by health systems to measure CRC test use is a promising alternative to measuring CRC test use with medical chart review and may be used to identify unscreened patients for screening interventions and track screening trends over time.

The cardiovascular health of urban African Americans: diet-related results from the Genes, Nutrition, Exercise, Wellness, and Spiritual Growth (GoodNEWS) trial.

African Americans have a higher incidence of cardiovascular disease (CVD) than Americans in general and are thus prime targets for efforts to reduce CVD risk. Dietary intake data were obtained from African Americans participating in the Genes, Nutrition, Exercise, Wellness, and Spiritual Growth (GoodNEWS) Trial. The 286 women and 75 men who participated had a mean age of 49 years; 53% had hypertension, 65% had dyslipidemia, and 51% met criteria for metabolic syndrome. Their dietary intakes were compared with American Heart Association and National Heart, Lung, and Blood Institute nutrition parameters to identify areas for improvement to reduce CVD risk in this group of urban church members in Dallas, TX. Results from administration of the Dietary History Questionnaire indicated median daily intakes of 33.6% of energy from total fat, 10.3% of energy from saturated fat, 171 mg cholesterol, 16.3 g dietary fiber, and 2,453 mg sodium. A beneficial median intake of 2.9 cups fruits and vegetables per day was coupled with only 2.7 oz fish/week and an excessive intake of 13 tsp added sugar/day. These data indicate several changes needed to bring the diets of these individuals--and likely many other urban African Americans--in line with national recommendations, including reduction of saturated fat, sodium, and sugar intake, in addition to increased intake of fatty fish and whole grains. The frequent inclusion of vegetables should be encouraged in ways that promote achievement of recommended intakes of energy, fat, fiber, and sodium.

Patterns of dural involvement in sinonasal tumors: prospective correlation of magnetic resonance imaging and histopathologic findings.

BACKGROUND: The presence of dural invasion serves as an important negative predictive factor for survival in sinonasal and skull-base neoplasms. The objective of this study was to prospectively correlate preoperative magnetic resonance imaging (MRI) findings with intraoperative surgical findings and histopathology to establish key correlates for dural involvement in sinonasal tumors. METHODS: Prospective blinded MRI review of 50 sinonasal and anterior skull-base neoplasms was performed by a staff neuroradiologist. Retrospective chart review was performed to accrue salient patient and tumor data. RESULTS: The mean patient age was 54.6 years with a male:female ratio of 1.8:1. The most common tumor histology included adenocarcinoma (18%), squamous cell carcinoma (18%), mucosal melanoma (8%), and olfactory neuroblastoma (8%). MRI demonstrated dural enhancement in 20 patients (40%), with 1 mm and ≥2 mm thickening being noted in 14 (70%) and 6 (30%) cases, respectively. Spectrum of MR findings in these 20 patients included linear enhancement in 15 (75%), nodular thickening in 5 (25%), and loss of hypointense zone in 13 (65%) cases. Intraoperative findings and histology confirmed dural invasion in 12 of 20 cases (60%). Positive predictive value (PPV) of linear and nodular dural enhancement for dural invasion was 46.7% and 100%, respectively. One millimeter (1 mm) and ≥2 mm of dural thickening demonstrated PPV of 42.9% and 100%, respectively. Loss of the hypointense zone had PPV of 92.3% for dural invasion. Fisher's exact test demonstrated that loss of hypointense zone and dural thickening ≥2 mm were statistically associated with dural involvement (p < 0.05). CONCLUSION: The presence of ≥2 mm of dural thickening, loss of hypointense zone, and nodular dural enhancement were highly predictive for presence of dural invasion by sinonasal malignant tumors. Preoperative knowledge of these MRI patterns may better guide surgical planning and patient counseling.

Increased myocardial prevalence of C-reactive protein in human coronary heart disease: direct effects on microvessel density and endothelial cell survival.

BACKGROUND: Elevated plasma C-reactive protein (CRP) is a biomarker of cardiovascular diseases (CVDs), but its potential roles as a participant of the disease process are not well defined. Although early endothelial cell injury and dysfunction are recognized events in CVD, the initiating events are not well established. Here we investigated the local myocardial CRP levels and cardiac microvessel densities in control and CVD tissue samples. Using in vitro methodologies, we investigated the direct effects of CRP on human endothelial cells. METHODS: Cardiac specimens were collected at autopsy within 4 h of death and were classified as normal controls or documented evidence of CVD. The regional prevalence of CRP and the cardiac microvessels (<40 µm) were investigated using immunohistochemistry. For in vitro experiments, human umbilical vein endothelial cells were incubated with CRP. Intracellular oxidant levels were assessed using 2',7'-dichlorofluorescein diacetate fluorescence microscopy, and cell survival was concurrently determined. Effects of chemical antioxidants on endothelial cell survival were also tested. RESULTS: Myocardial CRP levels were elevated in CVD specimens. This was associated with reduced cardiac microvessels, and this rarefaction was inversely correlated to adjacent myocardial CRP prevalence. CRP caused concentration-dependent increases in oxidant production and cell apoptosis. CONCLUSIONS: These findings provide evidence supporting myocardial CRP as a locally produced inflammatory marker and as a potential participant in endothelial toxicity and microvascular rarefaction.

Paranasal sinus and skull base fibro-osseous lesions: when is biopsy indicated for diagnosis?

BACKGROUND: Paranasal sinus fibro-osseous (FO) lesions represent a heterogeneous group, often sharing overlapping radiographic and pathologic features posing a dilemma in accurate diagnosis. The objective of this study was to correlate preoperative radiologic and postoperative histologic diagnosis to help guide a diagnostic algorithm. METHODS: Retrospective analysis of 60 FO lesions between 1994 and 2010. RESULTS: The mean age was 42.3 years with average follow-up of 12.5 months. The preliminary radiologic diagnosis was osteoma in 22 (36.7%), fibrous dysplasia (FD) in 9 (15%), ossifying fibroma (OF) vs FD in 5 (8.3%), and OF in 3 (5%) cases. The diagnosis was indeterminate in 21 (35%) cases. Management consisted of excision in 29 (48.3%), observation in 17 (28.3%), and biopsy in 14 (23.3%) patients. For patients undergoing resection or biopsy, positive predictive value of preoperative radiology was 100% (10/10) for osteoma, 85.7% (6/7) for FD, and 33.3% (1/3) for OF cases. For the indeterminate lesions, most common pathologic diagnoses for 21 patients included osteoma in 4 (17.4%), arrested pneumatization in 3 (14.3%), OF in 3 (14.3%), and FD in 2 (9.5%). For FD vs OF cases, 3 underwent surgery, revealing osteoma, FD, and OF in 1 patient each. CONCLUSION: In this series, radiologic-histopathologic correlation was high for osteoma and FD and low for OF and OF vs FD. This data suggests that patients with classic radiologic characteristics of osteoma and FD may be observed, unless resection is warranted based on clinical symptomatology. Preoperative diagnosis of OF, OF vs FD, or indeterminate lesions may warrant a biopsy to establish firm diagnosis to guide definitive management, especially if preoperative computed tomography (CT) imaging is concerning for an aggressive FO neoplasm.
