Trends in Cancer Incidence Rates in Georgia, 1982-2011

Background: Although data from the Surveillance, Epidemiology, and End results (SEER)-affiliated cancer registry are accessible to the public, there is a shortage of published research describing cancer incidences for White, Black, and other residents in Georgia. The objective of this research is to provide an overview of the trends in incidence of cancer in Georgia. Methods: Incidence data were obtained from the Surveillance, Epidemiology, and End Results (SEER) 9 program, supported by the National Cancer Institute, spanning the years 1982 to 2011. To assess trends over time, age-adjusted cancer incidence rates relative to the 2000 Standard US population and annual percent changes (APCs) were calculated using SEER*Stat software. Results: In Georgia, cancer incidence rates for women increased from 365.1 per 100,000 in 1982 to 404.2 per 100,000 in 2011, with an overall APC of 0.3% (95% confidence interval: 0.2 to 0.4), but, for men, cancer incidence rates showed a slight decline from 528.0 per 100,000 in 1982 to 513.7 per 100,000 in 2011 (APC of 0.2%, 95% CI: -0.6 to 0.1). For Black, White, and Other (Asian/Pacific Islanders/American Indians) females, there were increases in incidence in this period, with APC values of 0.6, 0.4, and 0.3, respectively. For all males and for Black and White males, there were overall decreases in incidence, with APC values of -0.2. For Other males, however, the APC value was -0.9. Conclusions: In Georgia, increases in cancer incidence rates occurred during 1982-2011 among the female population and within various racial groups in this population, but there was relative stability in incidence rates among the male population, except for Other males

Psychotropic Medications, Weight Gain and Chronic Diseases in a Correctional Setting: Impact on Women’s Health

Background: Studies with non-incarcerated populations have found a relationship between psychotropic medications and metabolic side effects, such as weight gain. Few studies have investigated the relationship between psychotropic medications associated with weight gain in prisoners, despite data showing that 73% of female and 55% of male offenders have a mental health problem and 15% have had medications prescribed. Methods: This longitudinal study investigated the relationship among psychotropic medications and weight gain in prisoners. We hypothesized that women prescribed psychotropic medications gain more weight than men. Data were extracted from Department of Corrections’ electronic health records. All prisoners with active records that included weight pre and post initiation of psychotropic medication were included in the study. Results: Women were prescribed antidepressants in higher proportions compared to men (χ2 = 58.3, p \u3c .01). The differences for antipsychotics were not significant (χ2 = 2.3, p = .13). There were no significant gender differences regarding the percentage of inmates who gained weight. In regard to changes in weight (kg), women on antidepressants gained more weight (mean 6.4 kg) compared to men (mean 2.0 kg), which was significant (p \u3c .01). Although women prescribed antipsychotics gained an average of 8.8 kg compared to men prescribed antipsychotics, who gained an average of 1.6 kg, this difference was not significant (p = .12). Further, there were no weight gain differences in terms of race or age in contrast to non-incarcerated populations. Conclusions: The significant weight gain among women prisoners raises important questions about the effects of incarceration on women’s health. Despite the significantly greater weight gain among women prisoners, other correlates of weight gain found in non-incarcerated populations are not evident in corrections

Gender Disparities in Weight Gain Among Offenders Who Are Obese Upon Entering Correctional Facilities

Background: Obesity is a significant health issue for offenders, who have a higher prevalence of obesity-related conditions, such as diabetes, compared to non-incarcerated populations. Within incarcerated populations, there are obesity disparities in terms of race, gender, and age, as well as excess weight gain during incarceration. Methods: This longitudinal study was conducted for 2005 – 2010 in collaboration with a Department of Corrections in the east south central region of the United States. From electronic health records of 10,841 offenders, weight, height, and demographic data were extracted. As determined from these data, 2,622 offenders met the inclusion criteria (two or more valid weight and height measurements and length of incarceration \u3e zero). Results: Women offenders who entered corrections as obese had a mean (and standard deviation) body mass index (BMI) of 36.2 (5.3) at baseline; the mean for men was 34.2 (4.4). For women who were obese at baseline, their BMI increased by 1.0 (3.3); for men their BMI decreased by 0.7 (3.1). Gender differences for changes in BMI among the obese population were significant (χ2 = 15.8, p \u3c 0.001). Women and men also differed in regard to weight gain (χ2 = 34.0, p \u3c 0.001). Further, those women and men who were not obese at baseline had an increase in BMI that was greater than the increase for the group that entered corrections as obese (p \u3e 0.001). Conclusions: Women offenders, obese or not at baseline, had greater gains in weight in comparison to men. However, there were no significant differences in BMI changes for race or correlations with age or length of incarceration. The findings related to gender warrant further investigations to explain these disparities and to evaluate the capacity of the corrections system to meet the health needs of women

Determinants of adherence to nutrition- related cancer prevention guidelines among African American breast cancer survivors

Background: Mortality rate for breast cancer is higher among African American (AA) women than for women of other racial/ethnic groups. Obesity, also higher among AA women, may increase the risk of breast cancer development and recurrence. Lifestyle factors such as healthy nutrition can reduce the rate of obesity and breast cancer. This study examined the determinants of adherence to nutrition-related cancer prevention guidelines among AA breast cancer survivors. Methods: AA breast cancer survivors (n=240) were recruited from a breast cancer support group to complete a lifestyle assessment tool for this cross-sectional study. Chi-square test and ordinal logistic regression analysis were used to examine the relationship between adherence to nutrition-related cancer prevention guidelines and potential predictors of adherence. Results: Majority of the survivors met the guideline for red and processed meat (n=191, 83.4%), but did not meet the guideline for fruits and vegetables (n=189, 80.4%). For survivors with annual household incomes \u3c $25,000, the odds of meeting or partially meeting the guideline for fruits and vegetables was 75.4$50,000 (OR= 0.25, 95% CI: 0.08, 0.80). Poor physical functioning (OR= 38.48, 95% CI: 2.26, 656.58), sleep disturbances (OR= 60.84, 95% CI: 1.61, 2296.02), and income \u3e $50,000 (OR= 51.02, 95% CI: 1.13, 2311.70) were associated with meeting the guideline for red and processed meat. Conclusions: Many AA breast cancer survivors are not meeting the nutrition-related cancer prevention guidelines. For this population, more interventions that enhance access to and consumption of healthy diets are needed

Effect of Long-Term Exposure to Lower Low-Density Lipoprotein Cholesterol Beginning Early in Life on the Risk of Coronary Heart Disease A Mendelian Randomization Analysis

ObjectivesThe purpose of this study was to estimate the effect of long-term exposure to lower plasma low-density lipoprotein cholesterol (LDL-C) on the risk of coronary heart disease (CHD).BackgroundLDL-C is causally related to the risk of CHD. However, the association between long-term exposure to lower LDL-C beginning early in life and the risk of CHD has not been reliably quantified.MethodsWe conducted a series of meta-analyses to estimate the effect of long-term exposure to lower LDL-C on the risk of CHD mediated by 9 polymorphisms in 6 different genes. We then combined these Mendelian randomization studies in a meta-analysis to obtain a more precise estimate of the effect of long-term exposure to lower LDL-C and compared it with the clinical benefit associated with the same magnitude of LDL-C reduction during treatment with a statin.ResultsAll 9 polymorphisms were associated with a highly consistent reduction in the risk of CHD per unit lower LDL-C, with no evidence of heterogeneity of effect (I2 = 0.0%). In a meta-analysis combining nonoverlapping data from 312,321 participants, naturally random allocation to long-term exposure to lower LDL-C was associated with a 54.5% (95% confidence interval: 48.8% to 59.5%) reduction in the risk of CHD for each mmol/l (38.7 mg/dl) lower LDL-C. This represents a 3-fold greater reduction in the risk of CHD per unit lower LDL-C than that observed during treatment with a statin started later in life (p = 8.43 × 10−19).ConclusionsProlonged exposure to lower LDL-C beginning early in life is associated with a substantially greater reduction in the risk of CHD than the current practice of lowering LDL-C beginning later in life

A Common KIF6 Polymorphism Increases Vulnerability to Low-Density Lipoprotein Cholesterol: Two Meta-Analyses and a Meta-Regression Analysis

Background: We sought to determine if a common polymorphism can influence vulnerability to LDL cholesterol, and thereby influence the clinical benefit derived from therapies that reduce LDL cholesterol. Methods: We conducted a meta-analysis of the association between a common Trp719Arg polymorphism in the kinesin-like protein 6 (KIF6) gene and the risk of cardiovascular disease (CVD), and a meta-regression analysis to measure the effect modification of this polymorphism on the association between LDL cholesterol and the risk of CVD. We used this measure of genetic effect modification to predict the expected difference in clinical benefit among KIF6 719Arg allele carriers and non-carriers in response to therapies that reduce LDL cholesterol. We then conducted a meta-analysis of statin trials to compare the expected difference in clinical benefit with the observed difference during treatment with a statin. Results: In a meta-analysis involving 144,931 participants, the KIF6 719Arg allele was not associated with the relative risk (RR) of CVD (RR: 1.02, 95%CI: 0.98-1.07, p = 0.288). Meta-regression analysis involving 88,535 participants, however, showed that the 719Arg allele appears to influence the effect of LDL cholesterol on the risk of CVD. KIF6 carriers experienced a 13% greater reduction in the risk of CVD per mmol/L decrease in LDL cholesterol than non-carriers. We interpreted this difference as the expected difference in clinical benefit among KIF6 carriers and non-carriers in response to therapies that lower LDL cholesterol. The difference in clinical benefit predicted by the increased vulnerability to LDL cholesterol among KIF6 carriers (ratio of RR: 0.87, 95%CI: 0.80-0.94, p = 0.001) agreed very closely with the observed difference among 50,060 KIF6 carriers and non-carriers enrolled in 8 randomized trials of statin therapy (ratio of RR: 0.87, 95%CI: 0.77-0.99, p = 0.038). Conclusion: The KIF6 719Arg allele increases vulnerability to LDL cholesterol and thereby influences the expected clinical benefit of therapies that reduce LDL cholesterol. © 2011 Ference et al

A Signature of Maternal Anti-Fetal Rejection in Spontaneous Preterm Birth: Chronic Chorioamnionitis, Anti-Human Leukocyte Antigen Antibodies, and C4d

Chronic chorioamnionitis is found in more than one-third of spontaneous preterm births. Chronic chorioamnionitis and villitis of unknown etiology represent maternal anti-fetal cellular rejection. Antibody-mediated rejection is another type of transplantation rejection. We investigated whether there was evidence for antibody-mediated rejection against the fetus in spontaneous preterm birth.This cross-sectional study included women with (1) normal pregnancy and term delivery (n = 140) and (2) spontaneous preterm delivery (n = 140). We analyzed maternal and fetal sera for panel-reactive anti-HLA class I and class II antibodies, and determined C4d deposition on umbilical vein endothelium by immunohistochemistry. Maternal anti-HLA class I seropositivity in spontaneous preterm births was higher than in normal term births (48.6% vs. 32.1%, p = 0.005). Chronic chorioamnionitis was associated with a higher maternal anti-HLA class I seropositivity (p<0.01), significant in preterm and term birth. Villitis of unknown etiology was associated with increased maternal and fetal anti-HLA class I and II seropositivity (p<0.05, for each). Fetal anti-HLA seropositivity was closely related to maternal anti-HLA seropositivity in both groups (p<0.01, for each). C4d deposition on umbilical vein endothelium was more frequent in preterm labor than term labor (77.1% vs. 11.4%, p<0.001). Logistic regression analysis revealed that chronic chorioamnionitis (OR = 6.10, 95% CI 1.29–28.83), maternal anti-HLA class I seropositivity (OR = 5.90, 95% CI 1.60–21.83), and C4d deposition on umbilical vein endothelium (OR = 36.19, 95% CI 11.42–114.66) were associated with preterm labor and delivery.A major subset of spontaneous preterm births has a signature of maternal anti-fetal cellular and antibody-mediated rejections with links to fetal graft-versus-host disease and alloimmune reactions

Determining left ventricular hypertrophy in overweight-obese youth using electrocardiogram criteria

Background and Purpose: There is an escalating prevalence of obesity in youth that increases the risk for cardiovascular alterations such as left ventricular hypertrophy (LVH). The purpose of this study is to identify the most effective electrical voltage measurement for determining LVH in youth who are overweight and obese. Methods: A retrospective chart review was conducted to determine sensitivity, specificity, and the receiver operator characteristic (ROC) curve of 4 popular electrical voltage measures. Results: Our findings indicated the sensitivity and specificity for Cornell product (50.0%; 96.2%), Cornell voltage (52.9%; 98.0%), Romhilt Estes (50.0%; 100.0%), and Sokolow-Lyon index (60.0%; 86.4%) consecutively. Conclusion: The Romhilt-Estes and Cornell voltage measures displayed the highest specificity and could prove to be beneficial as a screening method to rule out LVH in overweight and obese youth. © 2013 Springer Publishing Company
