Large-scale, multisite data sets offer the potential for exploring the public health benefits of biomedical interventions. Data harmonization is an emerging strategy to increase the comparability of research data collected across independent studies, enabling research questions to be addressed beyond the capacity of any individual study. The National Institute on Drug Abuse recently implemented this novel strategy to prospectively collect and harmonize data across 22 independent research studies developing and empirically testing interventions to effectively deliver an HIV continuum of care to diverse drug-abusing populations. We describe this data collection and harmonization effort, collectively known as the Seek, Test, Treat, and Retain Data Collection and Harmonization Initiative, which can serve as a model applicable to other research endeavors.
Tobacco Denormalization as a Public Health Strategy: Implications for Sexual and Gender Minorities

Published: October 2015

Although the population-level success of tobacco denormalization is widely accepted, it remains unclear whether these strategies alleviate health inequities for sexual and gender minorities. The high risk of smoking among sexual and gender minorities together with research that documents a relationship between stigma-related processes and smoking prevalence for these groups raises questions about whether tobacco-related stigma intensifies the disadvantages associated with the stigmas of other social identities. We have not adequately considered how tobacco-related stigma overlaps with other social identity stigmas. Given concerns about the intensification of inequality, this type of inquiry has important implications for understanding both the effectiveness and limitations of tobacco denormalization strategies for sexual and gender minorities and identifying those tobacco prevention, treatment, and public health policies that work to ameliorate health inequities.

Objectives. We determined the sustainability of effects of a school-based intervention to improve health behaviors and cardiovascular risk factors among middle school children. Methods. We administered a questionnaire and health screenings to 5 schools in Ann Arbor and 2 schools in Ypsilanti, Michigan. We assessed demographics, physiological factors, diet, physical activity, and sedentary behaviors from 1126 students who received a health curriculum (Project Healthy Schools) in the fall of sixth grade in 2005, 2006, and 2007. We administered the questionnaire and screening again in the spring and each subsequent spring through ninth grade to all available, consenting students. Results. In the 4 years following the school-based intervention, total cholesterol, low-density lipoprotein cholesterol, and triglycerides improved, and for most years systolic and diastolic blood pressure improved. Serum glucose and body mass index did not change. Physical activity increased and sedentary behaviors diminished. Conclusions. Project Healthy Schools is associated with sustainable improvements in both cardiovascular parameters and healthy behaviors.

Objectives. We sought to estimate rates of sexually transmitted infections (STIs) among criminal offenders in the 1 year after arrest or release from incarceration. Methods. We performed a retrospective cohort study of risk of having a positive STI (chlamydia, gonorrhea, or syphilis) or incident-positive HIV test in the 1 year following arrest or incarceration in Marion County (Indianapolis), Indiana. Participants were 247 211 individuals with arrest or incarceration in jail, prison, or juvenile detention between 2003 and 2008. Results. Test positivity rates (per 100 000 and per year) were highest for chlamydia (2968) and gonorrhea (2305), and lower for syphilis (278) and HIV (61). Rates of positive STI and HIV were between 1.5 and 2.8 times higher in female than male participants and between 2.7 and 6.9 times higher for Blacks than Whites. Compared with nonoffenders, offenders had a relative risk of 3.9 for chlamydia, 6.6 for gonorrhea, 3.6 for syphilis, and 4.6 for HIV. Conclusions. The 1-year period following arrest or release from incarceration represents a high-impact opportunity to reduce STI and HIV infection rates at a population level.

Objectives. We assessed the relation of childhood sexual abuse (CSA), intimate partner violence (IPV), and depression to HIV sexual risk behaviors among Black men who have sex with men (MSM). Methods. Participants were 1522 Black MSM recruited from 6 US cities between July 2009 and December 2011. Univariate and multivariable logistic regression models were used. Results. Participants reported sex before age 12 years with someone at least 5 years older (31.1%), unwanted sex when aged 12 to 16 years (30%), IPV (51.8%), and depression (43.8%). Experiencing CSA when aged 12 to 16 years was inversely associated with any receptive condomless anal sex with a male partner (adjusted odds ratio [AOR] = 0.50; 95% confidence interval [CI] = 0.29, 0.86). Pressured or forced sex was positively associated with any receptive anal sex (AOR = 2.24; 95% CI = 1.57, 3.20). Experiencing CSA when younger than 12 years, physical abuse, emotional abuse, having been stalked, and pressured or forced sex were positively associated with having more than 3 male partners in the past 6 months. Among HIV-positive MSM (n = 337), CSA between ages 12 and 16 years was positively associated with having more than 3 male partners in the past 6 months. Conclusions. Rates of CSA, IPV, and depression were high, but associations with HIV sexual risk outcomes were modest.

We determined the extent to which adolescents who have never used tobacco try e-cigarettes. Data on the prevalence and correlates of e-cigarette use among 482 179 California middle and high school students are from the 2013–2014 California Healthy Kids Survey. Overall, 24.4% had ever used e-cigarettes (13.4% have never used tobacco and 11.0% have used tobacco), and 12.9% were current e-cigarette users (5.9% have never used tobacco). Among those who have never used tobacco, males and older students were more likely to use e-cigarettes than females and younger students. Hispanics (odds ratio [OR] = 1.60; confidence interval [CI] = 1.53, 1.67) and those of other races (OR = 1.24; CI = 1.19, 1.29) were more likely than Whites to have ever used e-cigarettes, but only among those who had never used smokeless tobacco and never smoked a whole cigarette. E-cigarette use is very prevalent among California students who have never smoked tobacco, especially among Hispanic and other race students, males, and older students.
A Semianalytical Model for Production Simulation From Nonplanar Hydraulic-Fracture Geometry in Tight Oil Reservoirs
Authors: Yu Wei , Wu Kan , Sepehrnoori Kamy 
Published: October 2015

SummaryTwo key technologies such as horizontal drilling and hydraulic fracturing have led to the economic production of unconventional resources such as shale gas and tight oil. In reality, a nonplanar hydraulic-fracture geometry with varying fracture width and fracture permeability is created during the hydraulic-fracturing process. However, it is challenging to simulate well performance from the nonplanar fracture geometry. For the sake of simplicity, the nonplanar fracture geometry is often represented by ideal planar fracture geometry with constant fracture width, which one can easily handle analytically, semianalytically, and numerically. However, such ideal fracture geometry is inadequate to capture the physics of the transient flow behavior of the nonplanar fracture geometry. Although significant efforts were made in recent years to numerically model well performance from the complex fracture geometry, these approaches are still challenging to model the nonplanar fracture geometry with varying width because of a large considerable fracture-gridding issues and an expensive computation cost. In addition, the effect of nonplanar fracture geometry on well productivity and transient flow behavior was not reported in the literature. Hence, a model to handle the nonplanar fracture geometry by considering varying fracture width and fracture permeability is still lacking in the petroleum industry. Zhou et al. (2014) proposed a semianalytical model to handle the complex fracture geometry with constant fracture width. However, the semianalytical model did not consider the effects of stress-dependent fracture conductivity and the nonplanar fracture geometry as well as planar fracture geometry with varying fracture width along the fracture. In this work, we extended the semianalytical model to simulate production from the nonplanar fracture geometry as well as planar fracture geometry with varying width. In addition, the effect of stress-dependent fracture conductivity was implemented in the model. We verified the semianalytical model against a numerical reservoir simulator for single planar fracture with constant width. We performed two case studies. The first case contains a comparison of two planar fractures, one with constant fracture width and another with varying fracture width. In the second study, we compared two fractures with different fracture geometries such as planar fracture geometry and nonplanar fracture geometry, which were generated from the fracture-propagation model. In addition, transient flow regimes were investigated on the basis of a log-log graph of the dimensionless pressure drop and pressure-drop derivative vs. the dimensionless time. This work can provide critical insights into understanding the well performance from tight oil reservoirs with the nonplanar hydraulic-fracture geometry.
Derivation of high-order advection–diffusion schemes
Authors: Tkalich Pavel 
Published: October 2015

Using the interpolation polynomial method, major upwind explicit advection–diffusion schemes of up to fifth-order accuracy are rederived and their properties are explored. The trend emerges that the higher the order of accuracy of an advection scheme, the easier is the task of scheme stabilization and wiggling suppression. Thus, for a certain range of the turbulent diffusion coefficient, the stability interval of third- and fifth-order up-upwind explicit schemes can be extended up to three units of the Courant number (0≤c≤3).
Having good phase behavior, advection odd-order schemes are stable within a single computational cell (0≤c≤1). By contrast, even-order schemes are stable within two consecutive grid-cells (0≤c≤2), but exhibit poor dispersive properties. Stemming from the finding that considered higher-order upwind schemes (even, in particular) can be expressed as a linear combination of two lower-order ones (odd in this case), the best qualities of odd- and even-order algorithms can be blended within mixed-order accuracy schemes. To illustrate the idea, a Second-Order Reduced Dispersion (SORD) marching scheme and Fourth-Order Reduced Dispersion (FORD) upwind scheme are developed. Computational tests demonstrate a favorable performance of the schemes. In spite of the previous practice restricting usage of even-order upwind schemes (fourth-order in particular), they exhibit a potential to stand among popular algorithms of computational hydraulics.

Authors: Zhong-hua Liu , Jie Guo 
Published: October 2015

Purple potatoes were used as raw material to study the purple potato wine production process and antioxidant activity. This paper analyzed different fermentation time, fermentation temperature, yeast inoculum, initial pH, the initial sugar content on alcohol and anthocyanin contents of purple potato wine by single factor experiments and response surface methodology(RSM). The results showed that the optimum fermentation conditions of purple potato wine were as follows: fermentation temperature was 26oC, yeast inoculum was 0.15%, fermentation time was 7 d, initial pH was 3.0 and initial sugar content was 11 %. Under these conditions the alcohol and anthocyanin contents of purple potato wine could reach 10.55%/Vol and 6.42 μg/mL, respectively. The purple potato wine was purple, bright in colour, pleasant fragrance and pure taste. Prepared purple potato wine had the ability of reducing Fe3+ and scavenging superoxide anion radicals, which meant that purple potato wine had certain antioxidant activity.

Authors: Rinne Marjo , Garam Sanna , Häkkinen Arja , Ylinen Jari , Kukkonen-Harjula Katriina , Nikander Riku 
Published: October 2015

Background
Cervicogenic headache and migraine are common causes of visits to physicians and physical therapists. Few randomized trials utilizing active physical therapy and progressive therapeutic exercise have been previously published. The existing evidence on active treatment methods supports a moderate effect on cervicogenic headache.

Objective
The aim of this study is to investigate whether a progressive, group-based therapeutic exercise program decreases the intensity and frequency of chronic headache among women compared with a control group receiving a sham dose of transcutaneous electrical nerve stimulation (TENS) and stretching exercises.

Design
A randomized controlled trial with 6-month intervention and follow-up was developed. The participants were randomly assigned to either a treatment group or a control group.

Setting
The study is being conducted at 2 study centers.

Patients
The participants are women aged 18 to 60 years with chronic cervicogenic headache or migraine.

Intervention
The treatment group's exercise program consisted of 6 progressive therapeutic exercise modules, including proprioceptive low-load progressive craniocervical and cervical exercises and high-load exercises for the neck muscles. The participants in the control group received 6 individually performed sham TENS treatment sessions.

Measurements
The primary outcome is the intensity of headache. The secondary outcomes are changes in frequency and duration of headache, neck muscle strength, neck and shoulder flexibility, impact of headache on daily life, neck disability, fear-avoidance beliefs, work ability, and quality of life. Between-group differences will be analyzed separately at 6, 12, and 24 months with generalized linear mixed models. In the case of count data (eg, frequency of headache), Poisson or negative binomial regression will be used.

Limitations
The therapists are not blinded.

Conclusions
The effects of specific therapeutic exercises on frequency, intensity, and duration of chronic headache and migraine will be reported.

BACKGROUND: Obesity is associated with an increased risk of developing hyperinsulinemia, dyslipidemia, hypertension, premature atherosclerosis, and coronary artery disease in the future.AIM: This study is designed to assess the relationship between serum adiponectin, asymmetric dimethylarginine (ADMA), and lipid profile among Egyptian overweight and obese children.METHODS: This cross sectional case control study included 40 selected pre-pubertal overweight and obese children, 24 girls (60%) and 16 boys (40%) aged between 5 to 13 years (8.85 Â± 2.7 years), from new cases attending the National nutrition institute clinic during 2013. Forty apparently healthy children of matched age and sex were recruited as a control group.RESULTS: Obese group showed highly significant higher levels of serum ADMA, triglycerides, and total cholesterol compared with healthy controls (P <0.000 in all). However, serum adiponectin levels were highly significant lower in obese children compared to healthy controls (P < 0.000). Serum ADMA showed significant positive correlations with height, serum total cholesterol and serum triglycerides levels and significant negative correlation with the body mass index and weight for age z score.Â Serum adiponectin showed significant negative correlations with BMI, weight, and weight for age z score and significant positive correlation with serum triglycerides. By linear regression analysis; serum adiponectin, and serum triglycerides levels were significant predictors of high serum ADMA level (p =0.045 and 0.015 respectively). BMI, weight, height and serum triglycerides were significant predictors of low serum adiponectin levels (p = 0.005, 0.022, 0.026 and 0.015 respectively).CONCLUSIONS: Our results revealed that ADMA, Adiponectin and lipid profile can be considered as predictive biomarkers in prediction and prevention of atherosclerotic risk in the future among overweight and obese Egyptian children.

BACKGROUND: Diabetic peripheral neuropathy (DPN) often has reduced stability during standing conditions.AIM: To compare balance control in diabetic patients and normal subjects using computerized dynamic posturography and to assess effect of visual feedback-based balance training in DPN.MATERIALS AND METHODS: A total of 57 patients of type 2 diabetes mellitus and 30 age-matched normal control subjects were recruited. The sensory organization test was done before and after the training program.RESULTS: There was a significant decrease of mean (Â± SD) of composite equilibrium score and somatosensory ratio score between subgroups of DPN and control healthy group (p < 0.05).Â There was a significant increase of mean (Â± SD) of composite equilibrium score and the somatosensory ratio score after treatment as compared to results before training (p < 0.05) in mild DPN.Â Moreover, there were a significant correlation between composite equilibrium score and disease duration before training in the severe DPN (r = 0.368, p < 0.05).Â CONCLUSIONS: Computerized dynamic posturography is an important quantitative tool in the assessment of posture instability and allows for early disclosure of the failure of the postural control system. Visual feedback-based balance training was shown to be a promising method for fall prevention among early diabetes mellitus with peripheral neuropathy.

AIM: Textile workers in their work environment are exposed to airborne particulate from natural and synthetic origin. In the present study we aimed at assessment of prevalence and characterstics ofÂ COPD in never-smoking female workers employed at cotton weaving sector in textile manufacture.MATERIAL AND METHODS: In order to assess chronic prevalence and characteristics of chronic obstructive pulmonary disease (COPD) in textile industry we performed a cross-sectional study including 47 never-smoking female cotton workers (aged 36 to 56 years) and an equal number of never-smoking female office workers studied as a control. Evaluation of examined subjects consisted of completion of a questionnaire, baseline spirometry, and bronchodilator reversibility testing.RESULTS: We found higher prevalence of respiratory symptoms in cotton workers with significant difference for phlegm and dyspnea. Majority of the chronic respiratory symptoms in cotton workers were work-related. With exception of the mean value of forced vital capacity (FVC), the mean values of all other measured spirometric parameters in cotton workers were significantly lower than in office workers. The prevalence of COPD was significantly higher in cotton workers than in office workers (11.4% vs. 2.3%, P = 0,027). COPD in cotton workers was significantly associated with age higher than 45 years and with duration of exposure longer than 20 years.CONCLUSION: Our findings support data about relationship between occupational exposure to organic dust in textile workers and persistent airflow limitation.
