  4. Psychometric properties of the Center for Epidemiologic Studies Depression Scale in African American and Black Caribbean US adults.

    PubMed

    Torres, Elisa

    2012-10-01

    A 12-item version of the 20-item Center for Epidemiological Studies-Depression (CES-D) Scale was not validated in Black US adults but demonstrated strong psychometrics in other populations. Using data from the National Survey of American Life (n = 4,815), the psychometric properties of the scale were tested in African American and Black Caribbean adults. When compared with the DSM-IV-TR criteria for Major Depressive Disorder (MDD) and Dysthymia, most items in the CES-D Scale focus on depressed mood, providing evidence for content validity. Construct validity was questionable in African American and Black Caribbean men. The CES-D scores of African American men who met the DSM-IV-TR (APA, 2000) criteria for Dysthymia were not significantly different than African American men who did not (t = 1.9, p = .109). The CES-D scores of Black Caribbean men who met the DSM-IV-TR criteria for MDD were not significantly different than Black Caribbean men who did not (t = 1.6, p = .198), and none of the Black Caribbean men met the DSM-IV-TR criteria for Dysthymia. For the item, "I felt like everything I did was an effort," all groups had item-to-total correlations and inter-item correlations below .30. After eliminating this item, the alpha for the remaining 11 items was .80 and .76 in African American and Black Caribbean women, respectively. African American and Black Caribbean men also had item-to-total correlations and inter-item correlations below .30 for the item "I felt that I was just as good as other people." After eliminating these items, the alpha for the remaining 10 items was .73 in African American and Black Caribbean men. The cut-off score was 9 for the 11-item CES-D and 8 for the 10-item CES-D.

    The Severe Malaria in African Children (SMAC) network was established to conduct mortality-based trials. Although falciparum malaria kills more than one million children each year, single centers cannot enroll enough patients to detect reductions of 20–30% in mortality rates. Our aim was to quantify and describe severe malaria across a variety of epidemiological settings so that we could design intervention studies with more precise sample size estimates. We used a standardized surveillance mechanism to capture clinical, laboratory, and outcome data on all parasitemic children admitted to hospital. Between December 2000 and December 2003, 20,333 patients were enrolled in five sites. The frequency of severe malaria syndromes (cerebral malaria, severe malarial anemia and acidosis) differed between sites, as did the syndrome-specific mortality rates. Intervention studies targeted at reducing mortality in one or a combination of severe malaria syndromes would require 3–4 years to complete within the existing network. These data provide more accurate estimates of the disease burden of children hospitalized for malaria in sub-Saharan Africa. Networks are required to recruit enough patients for mortality-based studies and to encompass the epidemiological diversity of malaria in sub-Saharan Africa. SMAC represents the first effort to develop this capacity. PMID:16551469

  10. Utility of an African-centered support group for African American men confronting societal racism and oppression.

    PubMed

    Elligan, D; Utsey, S

    1999-05-01

    African American men suffer from the chronic stressor of living in a racist and oppressive society. This condition has historical roots dating back to enslavement and deportation from Africa to America. The psychological and physical difficulties that this group suffers from as a result of both the direct and the indirect influences of this chronic stressor have been well documented. However, a recent review of the literature revealed that not one article has been published in any of the major psychology journals that describes treatment issues or case studies focusing on this issue. This case study outlines the use of an African-centered group approach to helping African American men develop effective coping skills to successfully ameliorate the impact of societal racism and oppression on their lives.

    Racism constitutes a significant risk to the healthy development of African American youth. Fortunately, however, not all youth who experience racism evidence negative developmental outcomes. In this chapter, we examine person-centered analysis (PCA)-a quantitative technique that investigates how variables combine across individuals-as a useful tool for elucidating racial and ethnic protective processes that mitigate the negative impact of racism. We review recent studies employing PCA in examinations of racial identity, racial socialization, and other race-related experiences, as well as how these constructs correlate with and impact African American youth development. We also consider challenges and limitations of PCA and conclude with a discussion of future research and how PCA might be used to promote equity and justice for African American and other racial and ethnic minority youth who experience racism.

    Innovative strategies are needed to increase minorities' research participation. Using existing social networks within the African American community, "home health parties" were tested as a way to recruit African American women to a breast cancer control study. Parties included social, educational, and recruitment components. All women attending health parties consented, completed a survey, and received the study's preliminary breast cancer risk assessment. There were no differences in rates of participation for subsequent study components between women recruited via parties versus other methods. Health parties are viable recruitment strategies, reduce barriers to participation, provide a supportive environment, and are relatively inexpensive. PMID:17020516

  8. Mapping the African thunderstorm center in absolute units using Schumann resonance spectral decomposition method

    NASA Astrophysics Data System (ADS)

    2015-04-01

    Monitoring of the global lightning activity provides a very useful tool to study the global warming phenomenon and the other longer-scale climate changes induced by humans. The lightning activity is measured using various observational methods form space (optical satellite observations) as well as from the ground mostly by VLF /LF lightning detection networks, i.e. World Wide Lightning Location Network (WWLLN) or lightning detection network (LINET) in Europe. However, the global lightning activity measurements are possible only in the ELF range. Here we examine the African thunderstorm activity center, which is the most violent and active one. In a spherical damped resonator, such as the Earth-ionosphere cavity, the electromagnetic field is described by the solution of an inhomogeneous wave equation. For such equation the general solution can be expressed by the superposition of the solutions of the homogeneous equation, describing the resonance field, and the component, which is quite strong close to the source and weakens with source-observer separation. Thus, the superposition of the standing wave field with the field of traveling waves, which supply the energy from the lighting discharges to the global resonator, is a main reason for an asymmetric shape of the observational Schumann resonance (SR) power spectra, which highly deviate from the Lorentz curves. It is possible to separate this component from the signal using the spectrum decomposition method proposed by Kułak et al. [2006]. In our approach, we apply the inverse problem solution for determining the distance of the dominant lightning source. The distances to the thunderstorm centers are calculated using the analytical models for the electromagnetic waves propagation in the Earth-ionosphere cavity. Such forms of analytic solutions of the resonant field in the spherical cavity is the zonal harmonic series representation, described by Mushtak and Williams [2002] and we calculated the sets of such curves

    The Lifestyle Improvement through Food and Exercise (LIFE) study is a community-based randomized-controlled trial to measure the effectiveness of a lifestyle intervention to improve glycemic control among African Americans with type 2 diabetes attending safety net clinics. The study enrolled African American adults with a diagnosis of type 2 diabetes and HbA1c ≥ 7.0 who had attended specific safety net community clinics in the prior year. 210 patients will be enrolled and randomized to either the LIFE intervention or a standard of care control group, which consists of two dietitian-led diabetes self-management classes. The LIFE intervention was delivered in 28 group sessions over 12 months and focused on improving diet through dietitian-led culturally-tailored nutrition education, increasing physical activity through self-monitoring using an accelerometer, increasing ability to manage blood sugar through modifications to lifestyle, and providing social support for behavior change. In addition to the group sessions, peer supporters made regular telephone calls to participants to monitor progress toward behavioral goals and provide social support. The 12-month intervention phase was followed by a six-month maintenance phase consisting of two group sessions. The primary outcome of the study is change in A1C from baseline to 12 months, and an additional follow-up will occur at 18 months. The hypothesis of the study is that the participants in the LIFE intervention will show a greater improvement in glycemic control over 12 months than participants in the control group.

    The African penguin, Spheniscus demersus, the only penguin species that breeds in Africa, is endangered, and several diseases including avian malaria, babesiosis, and aspergillosis are common in some populations. From 2002 to 2010, spirochetes morphologically consistent with Borrelia were observed on thin blood smears from 115 of 8,343 (1.4%) African penguins admitted to rehabilitation centers in the Western Cape and Eastern Cape provinces of South Africa. Prevalence rates were significantly higher among chicks and juveniles compared with adults and for birds sampled during the summer months of October to February compared with winter months. The majority of infected birds were ultimately released, despite lack of antibiotic treatment; however, at least one bird is believed to have died of borreliosis based on characteristic gross and microscopic lesions. Analysis of partial flaB gene sequences indicated this was a relapsing fever Borrelia most similar to a Borrelia sp. detected in soft ticks from a seabird colony in Japan. This represents the fourth report of a relapsing fever Borrelia sp. in an avian species and highlights the need for additional studies of potentially pathogenic organisms infecting the African penguin in South Africa.

    African American and Latino males are less likely to seek mental health services and obtain adequate care than their White counterparts. They are more likely to receive mental health services in school-based health centers (SBHCs) than in other community-based setting. The purpose of this article was to understand the issues and reasons these adolescents sought mental health services at SBHCs and what their perceptions of the services were. A content analysis of 22 individual interviews was conducted using Krippendorff's method. Five themes emerged from the analysis of the data: the burdens and hurdles of my life, the door is always open, sanctuary within chaos, they get to us, and achieve my best potential. Each of the themes was explored in detail with rich quotations from the adolescents. The findings illuminated the daily struggles these adolescents faced and the impact mental health services in SBHCs had on their daily lives.

    Norms for African American elders on the Wechsler Memory Scale-Revised (WMS-R) were derived from a sample of 309 community-dwelling individuals participating in Mayo's Older African Americans Normative Studies (MOAANS). Normative estimates are provided for traditional WMS-R subtest scores and for supplemental procedures to evaluate forgetting rates and recognition memory. Tables are provided to convert raw WMS-R subtest and supplemental scores to age-corrected scaled scores. These may be further adjusted for years of education, if desired, by applying regression-based corrections. We anticipate that these data will enhance the diagnostic utility and clinical interpretation of WMS-R performance in older African Americans.

    Background There is a critical need to expand the pool of available kidneys for African Americans who are on the transplant wait-list due to the disproportionally lower availability of deceased donor kidneys compared with other races/ethnic groups. Encouraging living donation is one method to fill this need. Incorporating mHealth strategies may be a way to deliver educational and supportive services to African American transplant-eligible patients and improve reach to those living in remote areas or unable to attend traditional group-session-based programs. Before program development, it is essential to perform formative research with target populations to determine acceptability and cultivate a patient-centered and culturally relevant approach to be used for program development. Objective The objectives of this study were to investigate African American kidney transplant recipients’ and kidney donors’/potential donors’ attitudes and perceptions toward mobile technology and its viability in an mHealth program aimed at educating patients about the process of living kidney donation. Methods Using frameworks from the technology acceptance model and self-determination theory, 9 focus groups (n=57) were administered to African Americans at a southeastern medical center, which included deceased/living donor kidney recipients and living donors/potential donors. After a demonstration of a tablet-based video education session and explanation of a group-based videoconferencing session, focus groups examined members’ perceptions about how educational messages should be presented on topics pertaining to the process of living kidney donation and the transplantation. Questionnaires were administered on technology use and perceptions of the potential program communication platform. Transcripts were coded and themes were examined using NVivo 10 software. Results Qualitative findings found 5 major themes common among all participants. These included the following: (1

    Background Patient- and family-centered care (PFCC) has the potential to address disparities in access and quality of healthcare for African American pediatric asthma patients by accommodating and responding to the individual needs of patients and families. Study Objectives To identify and evaluate research on the impact of family–provider interventions that reflect elements of PFCC on reducing disparities in the provision, access, quality, and use of healthcare services for African American pediatric asthma patients. Methods Electronic searches were conducted using PubMed, CINAHL, and Psyclnfo databases. Inclusion criteria were peer-reviewed, English-language articles on family–provider interventions that (a) reflected one or more elements of PFCC and (b) addressed healthcare disparities in urban African American pediatric asthma patients (≤18years). Results Thirteen interventions or programs were identified and reviewed. Designs included randomized clinical trials, controlled clinical trials, pre-and post-interventions, and program evaluations. Conclusions Few interventions were identified as explicitly providing PFCC in d pediatric asthma context, possibly because of a Iack of consensus on what constitutes PFCC in practice. Some studies have demonstrated that PFCC improves satisfaction and communication during clinical interactions. More empirical research is needed to understand whether PFCC interventions reduce care disparities and improve the provision, access, and quality of asthma healthcare for urban African American children.

  5. African fossil tali: further multivariate morphometric studies.

    Analysis of measurements from the tali of 21 individual fossil primates from Africa shows that the specimens fall into five clearly defined groups. Accordingly, these specimens have been included as groups along with extant species in a subsequent canonical analysis thus allowing the fossils to play their part in the determination of the canonical separations. The results of this procedure show that the five fossil groups lie in a part of the canonical space not occupied by any extant African primate. Their positions are between the envelope of Asiatic apes (Hylobates and Pongo) and the envelope of African forms near the edge which contains Pan and Papio. One fossil group is so similar to Hylobates that its talus may have functioned in locomotion in a parallel manner. Others lie near to Pongo in directions proceeding towards Pan and Papio and it is possible that this similarity may indicate remnants of morphological adaptation for climbing in these fossils. At the same time, however, individual specimens are closer to one or another of the extant groups and this considerable spread suggests that the locomotor adaptations as evidenced by talar morphology, of the primate fauna in Africa, may have been very different from those of the present day. This would not the inconsistent with the different habitats, floras and non-primate faunas that may have characterized the East African scene at these earlier times. Particular fossils from Olduvai and Kromdraai that are supposed to be australopithecine and therefore bipeds, are confirmed (Oxnard, '72; Lisowski et al., '74) as being totally different from man in their talar morphology and essentially rather similar to the majority of the other fossil tali examined.

    2015-01-01

    Background Kidney transplantation rates in the United States are lower among African-Americans than among Whites. Well-documented racial disparities in access to transplantation explain some, but not all, of these differences. Prior survey-based research suggests that African-American dialysis patients are less likely than Whites to desire transplantation, but little research has focused on an in-depth exploration of preferences about kidney transplantation among African-Americans. Thus, the purpose of the study was to explore preferences, and compare patients’ expectations about transplantation with actual status on the transplant list. Methods We conducted semi-structured interviews with sixteen African-Americans receiving chronic hemodialysis. We analyzed the interviews using the constant comparative method of qualitative analysis. We also reviewed the dialysis center's transplant list. Results Four dominant themes emerged: 1) Varied desire for transplant; 2) Concerns about donor source; 3) Barriers to transplantation; 4) Lack of communication with nephrologists and transplant team. A thread of mistrust about equity in the transplantation process flowed through themes 2-4. In 7/16 cases, patients’ understanding of their transplant listing status was discordant with their actual status. Conclusions Our study suggests that many African-Americans on hemodialysis are interested in kidney transplantation, but that interest is often tempered by concerns about transplantation, including misconceptions about the risks to recipients and donors. Mistrust about equity in the organ allocation process also contributed to ambivalence. The discordance between patients’ perceptions of listing status and actual status suggests communication gaps between African-American hemodialysis patients and physicians. Clinicians should avoid interpreting ambivalence about transplantation as lack of interest. PMID:25769556

    This research report describes the process and results of recruiting African American adolescent girls and parents for a secondary weight gain prevention study. We sought to recruit 60 girls with equal representation of at-risk for overweight (BMI percentile 85-95) and overweight (BMI > 95th percentile), and at least one obese (BMI > 30 kg/m2) parent. A personal and individual recruitment approach was the sole method utilized for recruitment of participants into this two-year Internet-based study targeting weight gain prevention. Participants were randomized to either an interactive behavioral condition or a health-based education (control) condition. Fifty-seven African American adolescent girls and their parents were enrolled in the study conducted at a university-based nutrition research center. One hundred eight adolescent girls volunteered and met the study criteria on the first contact, 95 interviewed in the clinic, 64 were randomized, and 57 (89%) of those randomized began the study. Seven percent of the study sample was comprised of African American girls at-risk for overweight, while the majority (93%) of those enrolled were overweight (BMI > 95th percentile). Our study sample comprised an imbalanced number of overweight versus at-risk for overweight African American girls suggesting that perhaps a clinic-based secondary weight gain prevention study may be an inefficient and ineffective setting for recruiting this population. Although we were successful in recruiting a majority of overweight girls, we conclude that the imbalance in the number of participants recruited is likely related to the sociocultural environment that predisposes African American girls to obesity and a lack of awareness by the parents' of the consequences of being overweight.

    The use of Web-based methods for research recruitment and intervention delivery has greatly increased as Internet usage continues to grow. These Internet-based strategies allow for researchers to quickly reach more people. African-Americans are underrepresented in health research studies. Due to this, African-Americans get less benefit from important research that could address the disproportionate health outcomes they face. Web-based research studies are one promising way to engage more African-Americans and build trust with the African-American community. With African-Americans’ increasing access to the Internet using mobile phones and other mobile phone technologies, we advocate for efforts to increase the representation of African-Americans in research studies by using the Internet as a recruitment tool and conclude with recommendations that support this goal.

    This paper reports a study on South African learners' knowledge about scientific inquiry using the Views About Scientific Inquiry (VASI) Questionnaire. The sample consisted of 105 grade 11 learners from 7 schools across the socio-economic spectrum in a South African city. A rubric for scoring the VASI Questionnaire was developed and refined during the process of coding and is presented. Results showed that the learners held more informed views than that reported in previous international studies, except for particularly naive views regarding multiple methods of investigation. The results are discussed in terms of the Revised National Curriculum Statement (RNCS) that was taught from 2003 to 2010 in South African schools. This curriculum was founded on outcomes-based principles, valuing process skills rather than content. The study found that examples provided in the RNCS document correspond closely to the aspects of inquiry as described by the National Research Council. It is argued that the RNCS contributed to the more informed views about inquiry found among South African learners in this study.

    Geosciences investigations form the foundation for paleoanthropological research in the East African Rift System. However, innovative applications of tephra studies for constraining spatial and temporal relations of diverse geological processes, biostratigraphic records, and paleoenvironmental conditions within the East African Rift System were fueled by paleoanthropological investigations into the origin and evolution of hominids and material culture. Tephra is a collective, size-independent term used for any material ejected during an explosive volcanic eruption.The East African Rift System has become a magnet for paleoanthropological research ever since the discovery of the first hominids at Olduvai Gorge, in Tanzania, in the 1950s [Leakey et al., 1961]. Currently, numerous multidisciplinary scientific teams from academic institutions in the United States and Western Europe make annual pilgrimages for a couple of months to conduct paleoanthropological field research in the fossil-rich sedimentary deposits of the East African Rift System in Ethiopia, Kenya, and Tanzania. The field expedition consists of geological, paleontological, archaeological, and paleoenvironmental investigations.

    This qualitative study examined the experiences of HIV-positive African-American and African Caribbean childbearing women related to decisions about HIV testing, status disclosure, adhering to treatment, decisions about childbearing, and experiences in violent intimate relationships. Twenty-three women completed a 60-minute in-depth interview. Six themes emerged: perceived vulnerability to HIV infection; feelings about getting tested for HIV; knowledge, attitudes, and behaviors after HIV diagnosis; disclosure of HIV status; living with HIV (positivity, strength, and prayer); and, experiences with physical and sexual violence. Three women (13%) reported perinatal abuse and 10 women (n = 23, 43.4%) reported lifetime abuse. Positive experiences and resilience were gained from faith and prayer. Most important to the women were the perceived benefits of protecting the health of their baby. Findings suggest that policies supporting early identification of HIV-positive childbearing women are critical in order to provide counseling and education in forming their decisions for safety precautions in violent intimate partner relationships.

    Women of African descent have a high prevalence of diseases caused by insulin resistance. To positively impact cardiometabolic health in Black women, effective screening tests for insulin resistance must be identified. Recently, the TG/HDL-C ratio has been recommended as a tool to predict insulin resistance in overweight people. While the ratio predicts insulin resistance in White women, it is ineffective in African American women. As there are no data for African women, we tested the ability of the TG/HDL-C ratio to predict insulin resistance in Black women from South Africa, West Africa and the United States. For comparison, the ratio was also tested in White women from South Africa. Participants were 801 women (157 Black South African, 382 African American, 119 West African, 143 White South African, age 36 +/- 9y [mean +/- SD]). Standardized scores were created from log-transformed homeostasis model assessment-insulin resistance values from each population. Participants in the upper third of their population distribution were classified as insulin-resistant. To predict insulin resistance by the TC/HDL-C ratio, area under the receiver operating characteristic (AUC-ROC) curve was used and criteria were: 0.50 for no discrimination and > or = 0.70 for acceptable. Seventy-one percent of the Black women were overweight vs 51% of White women (P<.01). In overweight White women, AUC-ROC curve for prediction of insulin resistance by TG/HDL-C was 0.76 +/- 0.06, but below the 0.70 threshold in each group of overweight Black women (Black South African: 0.64 +/- 0.06, African American: 0.66 +/- 0.03, and West African: 0.63 +/- 0.07). Therefore, TG/HDL-C does not predict insulin resistance in overweight African American women and this investigation extends that finding to overweight Black South African and West African women. Resources to identify effective markers of insulin resistance are needed to improve cardiometabolic health in women of African descent.

    2014-08-01

    Little is known about how African American men with schizophrenia experience their every day existence. Through applying interpretive phenomenology and using a methodological structure designed by van Manen (1990, 1997), this research aimed to enrich the current understanding of what it is like for these African American males to live with schizophrenia. In this study, five men ranging in age from 21 to 57 described their lives within the context of existing with the diagnosis of schizophrenia. The lived experiences across the interviews revealed four overarching themes: They know that they are mentally ill; they make a special effort to test reality; they assert their autonomy and; they experience reality differently, which they see as a gift. To provide appropriate treatment support to African American males diagnosed with schizophrenia, it is important to recognize the clients' ability to assert their autonomy and appreciate each man's view of himself as unique and special. Moreover, in terms of symptom management, it is pivotal to understand that although the client may not be free of hallucinations and delusions, he nevertheless may be at his optimum state of wellness. The realization that these men have transcended their diagnosis of schizophrenia rather than being crushed by their condition is evident in their stories.

    The beneficial biologic effects attributed to vitamin D suggest a potential to influence overall mortality. Evidence addressing this hypothesis is limited, especially for African Americans who have a high prevalence of vitamin D insufficiency. The authors conducted a nested case-control study within the prospective Southern Community Cohort Study to relate baseline serum levels of 25-hydroxyvitamin D (25(OH)D) with subsequent mortality. Cases were 1,852 participants who enrolled from 2002 to 2009 and died >12 months postenrollment. Controls (n = 1,852) were matched on race, sex, age, enrollment site, and blood collection date. The odds ratios for quartile 1 (<10.18 ng/mL) versus quartile 4 (>21.64 ng/mL) levels of 25(OH)D were 1.60 (95% confidence interval (CI): 1.20, 2.14) for African Americans and 2.11 (95% CI: 1.39, 3.21) for non-African Americans. The effects were strongest for circulatory disease death, where quartile 1 versus quartile 4 odds ratios were 2.53 (95% CI: 1.44, 4.46) and 3.25 (95% CI: 1.33, 7.93) for African Americans and non-African Americans, respectively. The estimated odds of total mortality were minimized in the 25(OH)D range of 35-40 ng/mL. These findings provide support for the hypothesis that vitamin D status may have an important influence on mortality for both African Americans and non-African Americans.

    2007-03-06

    Data centers require continuous air conditioning to address high internal heat loads (heat release from equipment) and maintain indoor temperatures within recommended operating levels for computers. Air economizer cycles, which bring in large amounts of outside air to cool internal loads when weather conditions are favorable, could save cooling energy. There is reluctance from many data center owners to use this common cooling technique, however, due to fear of introducing pollutants and potential loss of humidity control. Concerns about equipment failure from airborne pollutants lead to specifying as little outside air as permissible for human occupants. To investigate contamination levels, particle monitoring was conducted at 8 data centers in Northern California. Particle counters were placed at 3 to 4 different locations within and outside of each data center evaluated in this study. Humidity was also monitored at many of the sites to determine how economizers affect humidity control. Results from this study indicate that economizers do increase the outdoor concentration in data centers, but this concentration, when averaged annually, is still below current particle concentration limits. Study results are summarized below: (1) The average particle concentrations measured at each location, both outside and at the servers, are shown in Table 1. Measurements show low particle concentrations at all data centers without economizers, regardless of outdoor particle concentrations. Particle concentrations were typically an order of magnitude below both outside particle concentrations and recently published ASHRAE standards. (2) Economizer use caused sharp increases in particle concentrations when the economizer vents were open. The particle concentration in the data centers, however, quickly dropped back to pre-economizer levels when the vents closed. Since economizers only allow outside air part of the time, the annual average concentrations still met the ASHRAE

    The purpose of this cross-sectional pilot study was to determine the prevalence and correlates of depressive symptoms and resiliency among 290 African American women (AAW) in a community-based primary health care center. Descriptive statistics, Pearson product-moment correlation, and logistic regression analyses were conducted. Findings indicate that depressive symptoms are experienced by 49% of the participants, while 10% indicated a history of suicidal ideation. Participants had moderately high resiliency scores that had a statistically significant inverse relationship with depressive symptoms. This suggests that resiliency is potentially a protective factor for depressive symptoms. Depressive symptoms were positively correlated with participants’ diagnosis of at least one chronic disease. The strongest predictors of depressive symptoms were previous diagnoses of a mental health condition and unemployment. This study identifies risk and potential protective factors for depression among a clinic sample of AAW. PMID:24241263

    2007-01-01

    The technique of Raman spectroscopy was used to examine the composition of ancient African domestic clay pottery of South African origin. One sample from each of four archaeological sites including Rooiwal, Lydenburg, Makahane and Graskop was studied. Normal dispersive Raman spectroscopy was found to be the most effective analytical technique in this study. XRF, XRD and FT-IR spectroscopy were used as complementary techniques. All representative samples contained common features, which were characterised by kaolin (Al 2Si 2O 5(OH) 5), illite (KAl 4(Si 7AlO 20)(OH) 4), feldspar (K- and NaAlSi 3O 8), quartz (α-SiO 2), hematite (α-Fe 2O 3), montmorillonite (Mg 3(Si,Al) 4(OH) 2·4.5H 2O[Mg] 0.35), and calcium silicate (CaSiO 3). Gypsum (CaSO 4·2H 2O) and calcium carbonates (most likely calcite, CaCO 3) were detected by Raman spectroscopy in Lydenburg, Makahane and Graskop shards. Amorphous carbon (with accompanying phosphates) was observed in the Raman spectra of Lydenburg, Rooiwal and Makahane shards, while rutile (TiO 2) appeared only in Makahane shard. The Raman spectra of Lydenburg and Rooiwal shards further showed the presence of anhydrite (CaSO 4). The results showed that South African potters used a mixture of clays as raw materials. The firing temperature for most samples did not exceed 800 °C, which suggests the use of open fire. The reddish brown and grayish black colours were likely due to hematite and amorphous carbon, respectively.

    Changing climate and hydro-meteorological boundary conditions are among the most severe challenges to Africa in the 21st century. In particular West Africa faces an urgent need to develop effective adaptation and mitigation strategies to cope with negative impacts on humans and environment due to climate change, increased hydro-meteorological variability and land use changes. To help meet these challenges, the German Federal Ministry of Education and Research (BMBF) started an initiative with institutions in Germany and West African countries to establish together a West African Science Service Center on Climate Change and Adapted Land Use (WASCAL). This activity is accompanied by an establishment of trans-boundary observation networks, an interdisciplinary core research program and graduate research programs on climate change and related issues for strengthening the analytical capabilities of the Science Service Center. A key research activity of the WASCAL Competence Center is the provision of regional climate simulations in a fine spatio-temporal resolution for the core research sites of WASCAL for the present and the near future. The climate information is needed for subsequent local climate impact studies in agriculture, water resources and further socio-economic sectors. The simulation experiments are performed using regional climate models such as COSMO-CLM, RegCM and WRF and statistical techniques for a further refinement of the projections. The core research sites of WASCAL are located in the Sudanian Savannah belt in Northern Ghana, Southern Burkina Faso and Northern Benin. The climate in this region is semi-arid with six rainy months. Due to the strong population growth in West Africa, many areas of the Sudanian Savannah have been already converted to farmland since the majority of the people are living directly or indirectly from the income produced in agriculture. The simulation experiments of the Competence Center and the Core Research Program are

  6. Examining science achievement of African American females in suburban middle schools: A mixed methods study

    NASA Astrophysics Data System (ADS)

    Topping, Kecia C.

    This dissertation examined factors that affected the science achievement of African American females in suburban middle schools. The research literature informed that African American females are facing the barriers of race, gender, socioeconomic status, and cultural learning style preferences. Nationally used measurements of science achievement such as the Standardized Achievement Test, Tenth edition (SAT-10), National Assessment for Educational Progress, and National Center for Educational Statistics showed that African American females are continuing to falter in the areas of science when compared to other ethnic groups. This study used a transformative sequential explanatory mixed methods design. In the first, quantitative, phase, the relationships among the dependent variables, science subscale SAT-10 NCE scores, yearly averages, and the independent variables, attitude toward science scores obtained from the Modified Fennema-Sherman Attitudes toward Science Scale, socioeconomics, and caregiver status were tested. The participants were 150 African American females in grades 6 through 8 in four suburban middle schools located in the Southeastern United States. The results showed a positive, significant linear relationship between the females' attitude and their science subscale SAT-10 NCE scores and a positive, significant linear relationship between the females' attitudes and their yearly averages in science. The results also confirmed that attitude was a significant predictor of science subscale SAT-10 NCE scores for these females and that attitude and socioeconomics were significant predictors of the females' yearly averages in science. In the second, qualitative, phase, nine females purposefully selected from those who had high and low attitude towards science scores on the scale in the quantitative phase were interviewed. The themes that emerged revealed seven additional factors that impacted the females' science achievement. They were usefulness of science

  12. "Reading" Central African Skies - A Case Study from Southeastern DRC

    NASA Astrophysics Data System (ADS)

    Roberts, Allen F.

    Little is known of the local astronomies of central Africa, and because of decades of horrific civil strife, this is particularly true of the Democratic Republic of the Congo (DRC). The present case study combines archival consideration of unpublished letters by earliest European visitors with ethnographic research in the mid-1970s among Tabwa and related peoples living along the western shores of and inland from Lake Tanganyika. Early data are very sparse, and in more recent days local astronomy is little-developed; but hypotheses are nonetheless possible about how people understood the regularities of the heavens as well as astonishing events like the apparition of Sungrazer Comets of the 1880s. A mnemonic logic shared by Tabwa, Luba, and other regional groups that was sometimes given material form or realized through performance arts may have informed how central African skies were "read" in earlier times.

    2010-01-01

    We consider the feasibility of reusing existing control data obtained in genetic association studies in order to reduce costs for new studies. We discuss controlling for the population differences between cases and controls that are implicit in studies utilizing external control data. We give theoretical calculations of the statistical power of a test due to Bourgain et al (Am J Human Genet 2003), applied to the problem of dealing with case-control differences in genetic ancestry related to population isolation or population admixture. Theoretical results show that there may exist bounds for the non-centrality parameter for a test of association that places limits on study power even if sample sizes can grow arbitrarily large. We apply this method to data from a multi-center, geographically-diverse, genome-wide association study of breast cancer in African-American women. Our analysis of these data shows that admixture proportions differ by center with the average fraction of European admixture ranging from approximately 20% for participants from study sites in the Eastern United States to 25% for participants from West Coast sites. However, these differences in average admixture fraction between sites are largely counterbalanced by considerable diversity in individual admixture proportion within each study site. Our results suggest that statistical correction for admixture differences is feasible for future studies of African-Americans, utilizing the existing controls from the African-American Breast Cancer study, even if case ascertainment for the future studies is not balanced over the same centers or regions that supplied the controls for the current study.

    2011-08-01

    To facilitate an increase in the amount of data on minority subjects collected for genetic databases, the authors attempted to clarify barriers to African-American participation in genetic studies. They randomly sampled 78,072 subjects from the community (Missouri Family Registry, 2002-2007). Of these, 28,658 participated in a telephone screening interview, 3,179 were eligible to participate in the genetic study, and 1,919 participated in the genetic study. Response rates were examined in relation to the proportion of subjects in the area who were African-American according to US Census 2000 zip code demographic data. Compared with zip codes with fewer than 5% African Americans (average = 2% African-American), zip codes with at least 60% African Americans (average = 87% African-American) had higher proportions of subjects with an incorrect address or telephone number but lower proportions of subjects who did not answer the telephone and subjects who refused the telephone interview (P < 0.0001). Based on reported race from the telephone screening, 71% of eligible African Americans and 57% of eligible European Americans participated in the genetic study (P < 0.0001). The results of this study suggest that increasing the number of African Americans in genetic databases may be achieved by increasing efforts to locate and contact them.

    2015-09-01

    Despite well-documented disparities in cancer pain outcomes among African Americans, surprisingly little research exists on adherence to analgesia for cancer pain in this group. We compared analgesic adherence for cancer-related pain over a 3-month period between African Americans and whites using the Medication Event Monitoring System (MEMS). Patients (N = 207) were recruited from outpatient medical oncology clinics of an academic medical center in Philadelphia (≥18 years of age, diagnosed with solid tumors or multiple myeloma, with cancer-related pain, and at least 1 prescription of oral around-the-clock analgesic). African Americans reported significantly greater cancer pain (P < .001), were less likely than whites to have a prescription of long-acting opioids (P < .001), and were more likely to have a negative Pain Management Index (P < .001). There were considerable differences between African Americans and whites in the overall MEMS dose adherence, ie, percentage of the total number of prescribed doses that were taken (53% vs 74%, P < .001). On subanalysis, analgesic adherence rates for African Americans ranged from 34% (for weak opioids) to 63% (for long-acting opioids). Unique predictors of analgesic adherence varied by race; income levels, analgesic side effects, and fear of distracting providers predicted analgesic adherence for African Americans but not for whites. Perspective: Despite evidence of disparities in cancer pain outcomes among African Americans, surprisingly little research exists on African Americans' adherence to analgesia for cancer pain. This prospective study uses objective measures to compare adherence to prescribed pain medications between African American and white patients with cancer pain.

    Roasted groundnut seeds, amaranth and dates pulp formed the center filling which was coated with sugar, breadings, desiccated coconut and roasted Bengalgram flour (BGF) to get 4 coated snacks. Physicochemical characteristics, microbiological profile, sorption behaviour and sensory quality of 4 coated snacks were determined. Centre filling to coating ratio of the products were in the range of 3:2-7:1, the product having BGF coating had the thinnest coating. Center filling had soft texture and the moisture content was 10.2-16.2% coating had lower moisture content (4.4-8.6%) except for Bengal gram coating, which had 11.1% moisture. Sugar coated snack has lowest fat (11.6%) and protein (7.2%) contents. Desiccated coconut coated snack has highest fat (25.4%) and Bengal gram flour coated snack had highest protein content (15.4%). Sorption studies showed that the coated snack had critical moisture content of 11.2-13.5%. The products were moisture sensitive and hence require packaging in films having higher moisture barrier property. In freshly prepared snacks coliforms, yeast and mold were absent. Mesophillic aerobes count did not show significant change during 90 days of storage at 27 °C and 37 °C. Sensory analysis showed that products had a unique texture due to combined effect of fairly hard coating and soft center. Flavour and overall quality of all the products were rated as very good.

    2010-07-01

    African-American women between 25 and 34 years of age are disproportionately affected by HIV/AIDS. Current prevention techniques, including education, have not had a significant influence on decreasing the rates of HIV and increasing safer sexual practices among some African-American women. This pilot study is one step towards increasing the understanding of this serious problem and developing effective interventions to stem the tide of HIV infection in African-American women. A grounded theory approach was used to address the process that unmarried, heterosexual, African-American women used to negotiate condom use with their sexual partner. Major concepts, connections between the categories, and theoretical codes are identified in this study and can be used to predict, speculate, explain, and understand the reported behavior of African-American women in negotiating condom use with their sexual partner.

  8. An engineering journey: A transcendental phenomenological study of African-American female engineers' persistence

    Somerville-Midgette, Kristy Nicole

    This transcendental phenomenological research study examined the perspectives and lived experiences of African-American female engineers related to the factors that led to their persistence to enter, persist through, and remain in the field. The study was guided by four research questions: (a) How do K-12 experiences shape African-American female engineers' decisions to enter the STEM field? (b) What persistence factors motivated African-American female engineers to enter the engineering profession? (c) What are the factors that shape African-American female engineers' persistence to progress through postsecondary engineering programs? (d) How do professional experiences shape African-American female engineers' persistence in the field? Cognitive interviewing techniques were used to validate data collection instruments. Interviews, focus groups, and timelines were used to collect data aimed at capturing the essence of the phenomenon of African-American engineers' persistence. The data was analyzed using Moustakas' (1994) phenomenological data analysis methods. The findings indicated that early academic experiences and achievement shaped participants' decision to enter the engineering field. Environmental factors, intrinsic motivation, support systems motivated participants to persist through postsecondary programs and to enter the engineering field. Further research is needed to examine the early academic experiences that encourage African-American females to enter engineering. In addition, research is needed to examine the barriers that lead to attrition of African-American females in engineering.

    2016-01-01

    Background Rapid steroid withdrawal (RSW) is used increasingly in kidney transplantation but long-term outcomes in African-American (AA) recipients are not well known. We compared 1 and 5 year transplant outcomes in a large cohort of AA patients who were maintained on continued steroid therapy (CST) to those who underwent RSW. Methods Post-transplant courses of A as receiving kidney allografts from 2003–2011 at two urban transplant centers in Chicago were followed. Prior to outcome analysis, we used Inverse Probability of Treatment Weights (IPTW) to match the two groups on a set of baseline risk factors. Graft and patient survival, GFR at 1 and 5 years, incidence and type of rejection, incidence of post-transplant diabetes mellitus (PTDM), delayed graft function, CMV and BK viremia were compared. Results There were 150 AA recipients in the CST analytic group and 157 in the RSW analytic group. Graft and patient survival was similar between the two groups. Rates of CMV viremia were higher in the RSW compared to the CST analytic group at 1 year. Biopsy-proven acute rejection and PTDM were similar between the RSW and CST groups. Conclusions In AA recipients, RSW has similar long-term outcomes to CST. PMID:27088051

    PubMed

    Diemer, Matthew A

    2002-02-01

    This exploratory study examined the identity constructions of African American men using a qualitative research methodology. Seven African American men, ranging in age from 20 to 47 years and whose education levels ranged from a 1st-year university student to a PhD, were interviewed for this study. Central to how all of these men defined themselves was the breadwinner or provider role. Participants emphasized education as "insurance" against discrimination and an awareness of educational and occupational opportunities. For these participants, education was a means of ensuring opportunity, which afforded fulfillment of the provider role. This study supports the work of N. Cazenave (1979, 1981), who demonstrated the salience of the provider role among African American men. The implications of the provider role among African American men for research are also discussed. The data also suggested diversity within the African American male experience. As 1 participant described African American men. "We come like flowers, you know. Some in bouquets, and some wild." By providing constructions of identity that diverge from existing negative stereotypes of African American men, this study attempted to deconstruct those stereotypes. Finally, this study provided a voice to an underrepresented group in the research literature.

One way that the U.S. Department of Energy (DOE) is addressing these challenges is by tasking the Battelle Energy Alliance, LLC (BEA) with developing the Center for Advanced Energy Studies (CAES) at the Idaho National Laboratory (INL). By 2015, CAES will be a self-sustaining, world-class, academic and research institution where the INL; DOE; Idaho, regional, and other national universities; and the international community will cooperate to conduct critical energy-related research, classroom instruction, technical training, policy conceptualization, public dialogue, and other events.

    The purpose of this study was to determine if there is adequate documentation of an historical role of African and African American involvement in science, engineering, and technology. Through the use of history of science and technology research methodology, along with an examination of the sociological and economic impacts of adequately accredited innovations and inventions contributed by Africans and African Americans, the researcher investigated their contributions to the following areas of science and technology: life science, physical sciences and chemistry, engineering, and science education. In regard to the timeframe for this study, the researcher specifically investigated African and African American involvement in science and technology that includes periods prior to black enslavement, scientific racism and colonialism, as well as during and after those periods. This research study reveals that there are adequate historical data regarding African and African American contributions to science, engineering, and technology. The data reveals that for many millennia African peoples have been continually involved in science and world science histories. The data further show that the numbers of African Americans acquiring BS, MS, Ph.D., Doctor of Science and Doctor of Engineering degrees in science and engineering disciplines are increasing. That these increases are not happening at a rate representative of the present or future African American percentages of the population. Consequently, because of future changes in our nation's demographics, increasing the numbers of people from under-represented groups who pursue scientific and engineering professions has become a matter of national security at the highest levels of government. Moreover, African Americans, Hispanics, and Native Americans are not pursuing careers or taking courses in science and engineering at a rate high enough to fulfill the prospective needs for the United States' industries, government

    Experiments on basic classical conditioning phenomena in adult and young Africanized honey bees (Apis mellifera L.) are described. Phenomena include conditioning to various stimuli, extinction (both unpaired and CS only), conditioned inhibition, color and odor discrimination. In addition to work on basic phenomena, experiments on practical applications of conditioning methodology are illustrated with studies demonstrating the effects of insecticides on learning and the reaction of bees to consumer products. Electron microscope photos are presented of Africanized workers, drones, and queen bees. Possible sub-species differences between Africanized and European bees are discussed.

    Genetic variation at insulin-like growth factor 1 (IGF1) has been linked to prostate cancer risk. However, the specific predisposing variants have not been identified. In this study, we fine-mapped the IGF1 locus for prostate cancer risk in African Americans. We conducted targeted Roche GS-Junior 454 resequencing of a 156-kb region of IGF1 in 80 African American aggressive prostate cancer cases. Three hundred and thirty-four IGF1 SNPs were examined for their association with prostate cancer risk in 1,000 African American prostate cancer cases and 991 controls. The top associated SNP in African Americans, rs148371593, was examined in an additional 3,465 prostate cancer cases and 3,425 controls of non-African American ancestry-European Americans, Japanese Americans, Latinos, and Native Hawaiians. The overall association of 334 IGF1 SNPs and prostate cancer risk was assessed using logistic kernel-machine methods. The association between each SNP and prostate cancer risk was evaluated through unconditional logistic regression. A false discovery rate threshold of q < 0.1 was used to determine statistical significance of associations. We identified 8 novel IGF1 SNPs. The cumulative effect of the 334 IGF1 SNPs was not associated with prostate cancer risk (P = 0.13) in African Americans. Twenty SNPs were nominally associated with prostate cancer at P < 0.05. The top associated SNP among African Americans, rs148371593 [minor allele frequency (MAF) = 0.03; P = 0.0014; q > 0.1], did not reach our criterion of statistical significance. This polymorphism was rare in non-African Americans (MAF < 0.003) and was not associated with prostate cancer risk (P = 0.98). Our findings do not support the role of IGF1 variants and prostate cancer risk among African Americans.

    Background Lack of regular physical activity at prescribed intensity levels is a modifiable risk factor for insulin resistance and the development of diabetes. African American men are at increased risk for developing diabetes and most African American men are not meeting the current recommended levels of physical activity. The primary objective of the Aerobic Plus Resistance Training and Insulin Resistance in African American Men (ARTIIS) study is to determine the effectiveness of an exercise training intervention aimed at reducing diabetes risk factors in African American men at risk for developing diabetes. Methods Insufficiently active 35–70 year old African American men with a family history of diabetes were eligible for the study. The 5-month randomized controlled trial assigns 116 men to an exercise training or healthy living control arm. The exercise training arm combines aerobic and resistance training according to the current national physical activity recommendations and is conducted in community (YMCA) facilities. The healthy living arm receives information promoting healthy lifestyle changes. Outcomes Insulin response to an oral glucose load is the primary outcome measure, and changes in physiological parameters, cardiorespiratory fitness, strength, body composition, and psychological well-being comprise the secondary outcomes. Conclusions The ARTIIS study is one of the first adequately powered, rigorously designed studies to investigate the effects of an aerobic plus resistance exercise training program and to assess adherence to exercise training in community facilities, in African American men.

    Objective To identify factors accounting for differences in glaucoma onset and rate of progression between individuals of African descent and European descent. Design A prospective, multicenter observational cohort study of 1221 participants of African descent and European descent with no glaucoma (normal), suspected glaucoma, and glaucoma. Six hundred eighty-six patient participants in the African Descent and Glaucoma Evaluation Study will be followed up longitudinally. Four hundred thirty-six participants of European descent from the Diagnostic Innovations in Glaucoma Study (DIGS) were also included. Baseline demographics, visual function (standard automated perimetry, short-wavelength automated perimetry, frequency doubling technology perimetry), optic nerve structure (retina tomography, optical coherence tomography), clinical status, and risk factors were measured. Results Individuals of African descent had (1) thinner corneas (P<.001) across all diagnostic groups, (2) a higher percentage of reported diabetes mellitus (P<.001) and high blood pressure (P<.001) and a lower percentage of reported heart disease (P=.001), and (3) worse pattern standard deviation for standard automated perimetry fields overall (P=.001) and within normal limits (P=.01) than individuals of European descent. No differences were present for mean intraocular pressure (P=.79). Conclusions Significant baseline differences were found in a number of clinical findings between persons of African descent compared with European descent. Longitudinal data from the African Descent and Glaucoma Evaluation Study will be important for determining which baseline features are important and predictive for accurate diagnosis and follow-up in this high-risk group.

    Objectives To evaluate the association of genetic variation with late-onset Alzheimer disease (AD) in African Americans, including genes implicated in recent genome-wide association studies of whites. Design We analyzed a genome-wide set of 2.5 million imputed markers to evaluate the genetic basis of AD in an African American population. Subjects Five hundred thirteen well-characterized African American AD cases and 496 cognitively normal African American control subjects. Setting Data were collected from multiple sites as part of the Multi-Institutional Research on Alzheimer Genetic Epidemiology (MIRAGE) Study and the Henry Ford Health System as part of the Genetic and Environmental Risk Factors for Alzheimer Disease Among African Americans (GenerAAtions) Study. Results Several significant single-nucleotide polymorphisms (SNPs) were observed in the region of the apolipoprotein E gene (APOE). After adjusting for the confounding effects of APOE genotype, one of these SNPs, rs6859 in PVRL2, remained significantly associated with AD (P=.0087). Association was also observed with SNPs in CLU, PICALM, BIN1, EPHA1, MS4A, ABCA7, and CD33, although the effect direction for some SNPs and the most significant SNPs differed from findings in data sets consisting of whites. Finally, using the African American genome-wide association study data set as a discovery sample, we obtained suggestive evidence of association with SNPs for several novel candidate genes. Conclusions Some genes contribute to AD pathogenesis in both white and African American cohorts, although it is unclear whether the causal variants are the same. A larger African American sample will be needed to confirm novel gene associations, which may be population specific. PMID:22159054

    The Technical Design Report for the SDC proposes a model for offline computing which includes a computing center at the SSCL, containing all of the physics data, together with a number of regional computing centers around the world. These regional centers would contain subsets of the data, and would support the daily work of most physicists. For large or unusual requests, where the data are not held at the regional center, the requests would automatically be forwarded to the SSCL. It is assumed that the closeness'' of the regional centers and their reduced demand from fewer users would result in improved system performance. Such a system is too complex to model analytically; simulation is the only viable approach. However, Monte Carlo models built from scratch for complicated systems are very difficult to maintain and hard to modify. Fortunately, we have obtained from IBM a modeling framework, RESQme, explicitly designed for building statistical models of computer systems. This note describes a first pass at modeling the proposed offline system.

    The aims of this study were: (i) to determine to what degree multiple sclerosis-associated loci discovered in European populations also influence susceptibility in African Americans; (ii) to assess the extent to which the unique linkage disequilibrium patterns in African Americans can contribute to localizing the functionally relevant regions or genes; and (iii) to search for novel African American multiple sclerosis-associated loci. Using the ImmunoChip custom array we genotyped 803 African American cases with multiple sclerosis and 1516 African American control subjects at 130 135 autosomal single nucleotide polymorphisms. We conducted association analysis with rigorous adjustments for population stratification and admixture. Of the 110 non-major histocompatibility complex multiple sclerosis-associated variants identified in Europeans, 96 passed stringent quality control in our African American data set and of these, >70% (69) showed over-representation of the same allele amongst cases, including 21 with nominally significant evidence for association (one-tailed test P < 0.05). At a further eight loci we found nominally significant association with an alternate correlated risk-tagging single nucleotide polymorphism from the same region. Outside the regions known to be associated in Europeans, we found seven potentially associated novel candidate multiple sclerosis variants (P < 10(-4)), one of which (rs2702180) also showed nominally significant evidence for association (one-tailed test P = 0.034) in an independent second cohort of 620 African American cases and 1565 control subjects. However, none of these novel associations reached genome-wide significance (combined P = 6.3 × 10(-5)). Our data demonstrate substantial overlap between African American and European multiple sclerosis variants, indicating common genetic contributions to multiple sclerosis risk.

    Genome wide association studies (GWAS) for type 2 diabetes (T2D) undertaken in European and Asian ancestry populations have yielded dozens of robustly associated loci. However, the genomics of T2D remains largely understudied in sub-Saharan Africa (SSA), where rates of T2D are increasing dramatically and where the environmental background is quite different than in these previous studies. Here, we evaluate 106 reported T2D GWAS loci in continental Africans. We tested each of these SNPs, and SNPs in linkage disequilibrium (LD) with these index SNPs, for an association with T2D in order to assess transferability and to fine map the loci leveraging the generally reduced LD of African genomes. The study included 1775 unrelated Africans (1035 T2D cases, 740 controls; mean age 54 years; 59% female) enrolled in Nigeria, Ghana, and Kenya as part of the Africa America Diabetes Mellitus (AADM) study. All samples were genotyped on the Affymetrix Axiom PanAFR SNP array. Forty-one of the tested loci showed transferability to this African sample (p < 0.05, same direction of effect), 11 at the exact reported SNP and 30 others at SNPs in LD with the reported SNP (after adjustment for the number of tested SNPs). TCF7L2 SNP rs7903146 was the most significant locus in this study (p = 1.61 × 10−8). Most of the loci that showed transferability were successfully fine-mapped, i.e., localized to smaller haplotypes than in the original reports. The findings indicate that the genetic architecture of T2D in SSA is characterized by several risk loci shared with non-African ancestral populations and that data from African populations may facilitate fine mapping of risk loci. The study provides an important resource for meta-analysis of African ancestry populations and transferability of novel loci. PMID:26635871

    The health and well-being of all individuals, independent of race, ethnicity, or gender, is a significant public health concern. Despite many improvements in the status of minority health, African American males continue to have the highest age-adjusted mortality rate of any race-sex group in the United States. Such disparities are accounted for by deaths from a number of diseases such as diabetes, human immunodeficiency virus (HIV), cancer, and cardiovascular disease, as well as by many historical and present social and cultural constructs that present as obstacles to better health outcomes. Distrust of the medical community, inadequate education, low socioeconomic status, social deprivation, and underutilized primary health care services all contribute to disproportionate health and health care outcomes among African Americans compared to their Caucasian counterparts. Results of clinical research on diseases that disproportionately affect African American males are often limited in their reliability due to common sampling errors existing in the majority of biomedical research studies and clinical trials. There are many reasons for underrepresentation of African American males in clinical trials, including their common recollection and interpretation of relevant historical of biomedical events where minorities were abused or exposed to racial discrimination or racist provocation. In addition, African American males continue to be less educated and more disenfranchised from the majority in society than Caucasian males and females and their African American female counterparts. As such, understanding their perceptions, even in early developmental years, about health and obstacles to involvement in research is important. In an effort to understand perspectives about their level of participation, motivation for participation, impact of education, and engagement in research, this study was designed to explore factors that impact their willingness to participate.

    Guangzhou is China's third most populous city, and the region's burgeoning manufacturing economy has attracted many young African businessmen and entrepreneurs to the city. The aims of this study were to examine strategies that African migrants in Guangzhou have adopted in response to health-care barriers, and explore their perceptions of how to address their needs. Twenty-five semi-structured interviews and two focus groups were conducted among African migrants residing in Guangzhou, China. Facing multiple barriers to care, African migrants have adopted a number of suboptimal and unsustainable approaches to access health care. These included: using their Chinese friends or partners as interpreters, self-medicating, using personal connections to medical doctors, and travelling to home countries or countries that offer English-speaking doctors for health care. Health-care providers and health organisations in Guangzhou have not yet acquired sufficient cultural competence to address the needs of African migrants residing in the city. Introducing linguistically and culturally competent health-care services in communities concentrated with African migrants may better serve the population. With the growing international migration to China, it is essential to develop sustainable approaches to improving health-care access for international migrants, particularly those who are marginalised.

    Few HIV/STI interventions exist for African American adolescent girls in juvenile detention. The objective was to evaluate the efficacy of an intervention to reduce incident STIs, improve HIV-preventive behaviors, and enhance psychosocial outcomes. We conducted a randomized controlled trial among African American adolescent girls (13-17 years, N = 188) in juvenile detention from March 2011 to May 2012. Assessments occurred at baseline and 3- and 6-months post-randomization and included: audio computer-assisted self-interview, condom skills assessment, and self-collected vaginal swab to detect Chlamydia and gonorrhea. The Imara intervention included three individual-level sessions and four phone sessions; expedited partner therapy was offered to STI-positive adolescents. The comparison group received the usual care provided by the detention center: STI testing, treatment, and counseling. At the 6-month assessment (3-months post-intervention), Imara participants reported higher condom use self-efficacy (p < 0.001), HIV/STI knowledge (p < 0.001), and condom use skills (p < 0.001) compared to control participants. No significant differences were observed between trial conditions in incident Chlamydia or gonorrhea infections, condom use, or number of vaginal sex partners. Imara for detained African American adolescent girls can improve condom use skills and psychosocial outcomes; however, a critical need for interventions to reduce sexual risk remains. PMID:25190056

The study identified thoughts, feelings, emotions, and challenges that teachers faced when instructing successful African American students from Title I schools in rural community classrooms. The research study analysis utilized NVivo10RTM software and identified common themes in the data. Five themes emerged from interviews with five fifth- and eighth-grade science teachers. Based on the teachers' perceptions, the findings revealed: (a) teachers experience an emotional journey in high poverty schools; (b) investments encompass sacrificing whatever is needed to help students become successful; (c) relationships should be developed between the teacher and student; (d) intentionality is a part of teachers' daily interaction with students; and (e) teachers encounter a challenging opportunity instructing African American students in science. This study provides valuable data in understanding the experiences of teachers as they instruct successful African American students and the challenges, obstacles, and triumphs teachers face when working with this population of students. The implications of the study suggest that educational leaders provide emotional support to help teachers manage the plethora of emotions experienced on a daily basis. Future study of successful teachers of African American students may further inform the dearth of literature surrounding the experience of successful teachers of minority students.

    Objective We investigated the user requirements of African-American youth (aged 14–24 years) to inform the design of a culturally appropriate, network-based informatics intervention for the prevention of HIV and other sexually transmitted infections (STI). Materials and Methods We conducted 10 focus groups with 75 African-American youth from a city with high HIV/STI prevalence. Data analyses involved coding using qualitative content analysis procedures and memo writing. Results Unexpectedly, the majority of participants’ design recommendations concerned trust. Youth expressed distrust towards people and groups, which was amplified within the context of information technology-mediated interactions about HIV/STI. Participants expressed distrust in the reliability of condoms and the accuracy of HIV tests. They questioned the benevolence of many institutions, and some rejected authoritative HIV/STI information. Therefore, reputational information, including rumor, influenced HIV/STI-related decision making. Participants’ design requirements also focused on trust-related concerns. Accordingly, we developed a novel trust-centered design framework to guide intervention design. Discussion Current approaches to online trust for health informatics do not consider group-level trusting patterns. Yet, trust was the central intervention-relevant issue among African-American youth, suggesting an important focus for culturally informed design. Our design framework incorporates: intervention objectives (eg, network embeddedness, participation); functional specifications (eg, decision support, collective action, credible question and answer services); and interaction design (eg, member control, offline network linkages, optional anonymity). Conclusions Trust is a critical focus for HIV/STI informatics interventions for young African Americans. Our design framework offers practical, culturally relevant, and systematic guidance to designers to reach this underserved group

    The present study was a prospective, naturalistic, longitudinal investigation of the two year course of posttraumatic stress disorder (PTSD) in a sample of African Americans with anxiety disorders. The study objectives were to examine the two year course of PTSD and to evaluate differences between African Americans with PTSD and anxiety disorders and African Americans with anxiety disorders but no PTSD with regard to comorbidity, psychosocial impairment, physical and emotional functioning, and treatment participation. The participants were 67 African Americans with PTSD and 98 African Americans without PTSD (mean age 41.5 years, 67.3% female). Individuals with PTSD were more likely to have higher comorbidity, lower functioning, and they were less likely to seek treatment than those with other anxiety disorders but no PTSD. The rate of recovery from PTSD over two years was 0.10 and recovery from comorbid Major Depressive Disorder was 0.55. PTSD appears to be persistent over time in this population. The rates of recovery were lower than what has been reported in previous longitudinal studies with predominantly non-Latino Whites. It is imperative to examine barriers to treatment and factors related to treatment engagement for this population.

    It has been suggested that southern Africa is the origin of the predominantly herbaceous Apiaceae subfamily Apioideae and that the woody habit is plesiomorphic. We expand previous molecular phylogenetic analyses of the family by considering all but three of the approximately 38 genera native to southern Africa, including all genera whose members, save one, have a woody habit. Representatives of five other genera are included because they may be closely related to these southern African taxa. Chloroplast DNA rps16 intron and/or nuclear rDNA ITS sequences for 154 accessions are analyzed using maximum parsimony, Bayesian, and maximum likelihood methods. Within Apioideae, two major clades hitherto unrecognized in the subfamily are inferred. The monogeneric Lichtensteinia clade is sister group to all other members of the subfamily, whereas the Annesorhiza clade (Annesorhiza, Chamarea, and Itasina) plus Molopospermum (and Astydamia in the ITS trees) are the successive sister group to all Apioideae except Lichtensteinia. Tribe Heteromorpheae is expanded to include Pseudocarum, "Oreofraga" ined., and five genera endemic to Madagascar. The southern African origin of subfamily Apioideae is corroborated (with subsequent migration northward into Eurasia along two dispersal routes), and the positions of the herbaceous Lichtensteinia and Annesorhiza clades within the subfamily suggest, surprisingly, that its ancestor was herbaceous, not woody.

    Many studies have been conducted in the area of job satisfaction. Its necessary attributes sor components have been studied, analyzed, validated, standardized, and normed, onpredominantly white male populations. Few of these studies have focused on people of color, specifically African-Americans, and fewer still on those African-Americans working in a high-tech, scientific and research environments. The researchers have defined what is necessary for the current dominent culture`s population, but are their findings applicable and valid for our nation`s other cultures and ethnic groups? Among the conclusions: the subjects felt that there was no real difference in job satisfiers from their white colleagues; however the subjects had the sense of community (African-American) and the need to give back to it. Frustrations included politics, funding, and lack of control.

    The data center in this study had a total floor area of 8,580 square feet (ft{sup 2}) with one-foot raised-floors. It was a rack lab with 440 racks, and was located in a 208,240 ft{sup 2} multi-story office building in San Jose, California. Since the data center was used only for testing equipment, it was not configured as a critical facility in terms of electrical and cooling supply. It did not have a dedicated chiller system but served by the main building chiller plant and make-up air system. Additionally, it was served by a single electrical supply with no provision for backup power. The data center operated on a 24 hour per day, year-round cycle, and users had all hour full access to the data center facility. The study found that data center computer load accounted for 23% of the overall building electrical load, while the total power consumption attributable to the data center including allocated cooling load and lighting was 30% of the total facility load. The density of installed computer loads (rack load) in the data center was 63 W/ft{sup 2}. Power consumption density for all data center allocated load (including cooling and lighting) was 84 W/ft{sup 2}, approximately 12 times the average overall power density in rest of the building (non-data center portion). For the data center, 75% of the overall electric power was the rack critical loads, 11% of the power was consumed by chillers, 9% by CRAH units, 1% by lighting system, and about 4% of the power was consumed by pumps. The ratio of HVAC to IT power demand in the data center in this study was approximately 0.32. General recommendations for improving overall data center energy efficiency include improving the lighting control, airflow optimization, and control of mechanical systems serving the data center in actual operation. This includes chilled water system, airflow management and control in data centers. Additional specific recommendations or considerations to improve energy efficiency are provided

    The purpose of the present investigation was to describe the experiences of African American women student-athletes and the role that coaches play in those experiences. This study profiles 4 women who participated in National Collegiate Athletic Association Division I cross-country, crew, track and field, and volleyball. Using data gathered through the qualitative methods of document analysis, background questionnaires, focus groups, grounded surveys, and in-depth individual interviews, the results of the study are focused on how coaches affect individual student-athletes and, most specifically, a particular segment of the athletic world that tends to be overlooked: the African American woman. Results are organized according to the following themes that emerged through the collection of data: (a) the involvement of coaches in African American women student-athletes' exposure to racism through stereotypes, (b) coaches as significant influences on African American women becoming involved and remaining involved in sport, and (c) power structures in sport and society affecting African American women as a form of institutional racism. A practical applications section follows the results.

    A genome-wide scan of high-risk prostate cancer families in North America has demonstrated linkage of a particular marker to Chromosome 1q (HPC1). An even greater proportion of African-American families have shown linkage to HPC1. Therefore, investigators at the National Human Genome Research Institute (NHGRI) in collaboration with Howard University and a predominantly African-American group of urologists established the African-American Hereditary Prostate Cancer (AAHPC) Study Network to confirm the suggested linkage of HPC in African Americans with a gene on Chromosome 1. Blood samples from recruited families were sent to Howard University for extraction of DNA. The DNA was sent to NHGRI at NIH where the genotyping and genetic sequence analysis was conducted. Genotype data are merged with pedigree information so that statistical analysis can be performed to establish potential linkage. From March 1, 1998, to June 1, 1999, a total of 40 African-American families have been recruited who met the study criteria. Preliminary results suggest that racial/ethnicity grouping may affect the incidence and extent of linkage of prostate cancer to specific loci. The importance of these findings lays in the future treatment of genetic-based diseases.

    Genomic research is one of the tools for elucidating the pathogenesis of diseases of global health relevance and paving the research dimension to clinical and public health translation. Recent advances in genomic research and technologies have increased our understanding of human diseases, genes associated with these disorders, and the relevant mechanisms. Genome-wide association studies (GWAS) have proliferated since the first studies were published several years ago and have become an important tool in helping researchers comprehend human variation and the role genetic variants play in disease. However, the need to expand the diversity of populations in GWAS has become increasingly apparent as new knowledge is gained about genetic variation. Inclusion of diverse populations in genomic studies is critical to a more complete understanding of human variation and elucidation of the underpinnings of complex diseases. In this review, we summarize the available data on GWAS in recent African ancestry populations within the western hemisphere (i.e. African Americans and peoples of the Caribbean) and continental African populations. Furthermore, we highlight ways in which genomic studies in populations of recent African ancestry have led to advances in the areas of malaria, HIV, prostate cancer, and other diseases. Finally, we discuss the advantages of conducting GWAS in recent African ancestry populations in the context of addressing existing and emerging global health conditions.

The purpose of this study was to explore African-American girls' perceptions offactors that contribute to girls being less physically active in high school. Interpretative Phenomenological Analysis (IPA) was used to identify individual perceptions of girls regarding physical activity. This resulted in four themes: personal appearances, scheduling/timing of classes, environmental/facilities issues, and lack of variety of activities in PE classes. Thefindings from this study indicated that African-American adolescent girls did not feel the physical or social school environment encouraged or supported them to be physically active.

    DX centers induced by both group-III and group-VII donors in CdTe are studied using density functional calculations. The results show that, for group-VII donors, the DX centers with a cation-cation bond ({alpha}- and {beta}-CCB-DX centers) are more stable than the previously proposed broken-bond DX (BB-DX) center and the {beta}-CCB-DX center is the most stable. The stability trend found for the CCB-DX centers for different donors in CdTe is consistent with that for GaAs and GaSb, which suggests a general rule that the CCB-DX centers are favored for small donor atoms on anion site especially for semiconductors with large anion size.

    Over 80% of African-American (AA) women are overweight or obese. A large racial disparity between AA and European-Americans (EA) in obesity rates exists among women, but curiously not among men. Although socio-economic and/or cultural factors may partly account for this race-by-sex interaction, the potential involvement of genetic factors has not yet been investigated. Among 2814 self-identified AA in the Atherosclerosis Risk in Communities study, we estimated each individual's degree of West-African genetic ancestry using 3437 ancestry informative markers. We then tested whether sex modifies the association between West-African genetic ancestry and body mass index (BMI), waist-circumference (WC), and waist-to-hip ratio (WHR), adjusting for income and education levels, and examined associations of ancestry with the phenotypes separately in males and females. We replicated our findings in the Multi-Ethnic Study of Atherosclerosis (n = 1611 AA). In both studies, we find that West-African ancestry is negatively associated with obesity, especially central obesity, among AA men, but not among AA women (pinteraction = 4.14 × 10−5 in pooled analysis of WHR). In conclusion, our results suggest that the combination of male gender and West-African genetic ancestry is associated with protection against central adiposity, and suggest that the large racial disparity that exists among women, but not men, may be at least partly attributed to genetic factors.

    BACKGROUND: African Americans' mistrust of healthcare is often cited as a cause of racial disparities in health and has been linked to cultural mistrust. African-American parents' level of cultural mistrust while in a general healthcare setting has not been previously measured. OBJECTIVE: To determine the performance, participant acceptance, feasibility of administration and demographic associations of a measure of cultural mistrust, the Cultural Mistrust Inventory (CMI), in African-American parents seeking healthcare. METHODS: A cross-sectional sample of 69 self-identified African-American parents of minor children recruited in a university-affiliated, urban pediatric/family practice outpatient clinic completed an anonymous, self-administered questionnaire containing demographic items and the CMI. RESULTS: The response rate was 91% (n=63), and 49 (78%) -- answered all questions. Measured mistrust did not vary with gender, insurance or education. The CMI's internal consistency was similar to previously published studies of the instrument (alpha=0.92). Parents indicating discomfort with the CMI's questions reported significantly less mistrust than parents who did not indicate discomfort (p=0.01). CONCLUSIONS: The CMI is feasible to administer in a clinic setting and demonstrates good internal consistency. It can be a useful tool to assess the effect of cultural mistrust on the healthcare decisions African-American parents make for their children. However, when measuring cultural mistrust in a healthcare setting, respondents' comfort with the survey questions should be assessed. PMID:17304964

    Background African Americans are disproportionately burdened by HIV. The African American church is an influential institution with potential to increase reach of HIV prevention interventions in Black communities. Purpose This study examined HIV testing rates in African American churches in the Taking It to the Pews pilot project. Using a community-engaged approach, church leaders delivered religiously-tailored HIV education and testing materials/activities (e.g., sermons, brochures/bulletins, testimonials) to church and community members. Methods Four African American churches (N=543 participants) located in the Kansas City metropolitan area were randomized to intervention and comparison groups. Receipt of an HIV test was assessed at baseline and 6 months. Results Findings indicated intervention participants were 2.2 times more likely to receive an HIV test than comparisons at 6 months. Church leaders delivered about 2 tools per month. Conclusions Church-based HIV testing interventions are feasible and have potential to increase HIV testing rates in African American communities.

    Fragile X syndrome (FXS) is an inherited genetic condition with critical consequences to the proband and family members at all levels in the generations. Although evidence demonstrates that the rates of diagnosis for FXS are the same in all racial groups, age of diagnosis in African American children has been reported to occur later than in Caucasian children. Additionally, African American families are seriously under-represented in existing FXS research studies. As such, it is important to understand the possible disparities in the underlying factors to receiving a diagnosis in African American families with FXS. Herein, a qualitative approach was adopted to describe the overall FXS diagnosis experiences (pre-diagnosis, diagnosis, and post-diagnosis stages) of a convenience sample of 10 African American mothers. We identified three major findings among our participants: (1) FXS testing is not ordered immediately once a parent expresses concerns of developmental delays to the pediatricians, (2) the diagnosis is sometimes delivered in an insensitive manner with information often being outdated and unbalanced towards negative aspects, (3) communication issues among family members exists once the diagnosis is discovered. Although these qualitative data may not be representative of the whole group, these findings have significant implications for genetic counseling and our understanding in providing support and advocacy for African American families with FXS.

Whether this trait is attributable to genetic factors in African-origin populations, or a result of inadequately measured environmental exposures, such as racial discrimination, is not known. To study this question we conducted a multi-site comparative study of communities in the African diaspora, drawn from metropolitan Chicago, Kingston, Jamaica, rural Ghana, Cape Town, South Africa, and the Seychelles. Methods At each site 500 participants between the ages of 25 and 49, with approximately equal sex balance, were enrolled for a longitudinal study of energy expenditure and weight gain. In this report we describe the patterns of blood pressure and hypertension observed at baseline among the sites. Results Mean systolic and diastolic blood pressures were very similar in the US and South Africa in both men and women, although among women the prevalence of hypertension was higher in the US (24 vs. 17%, respectively). After adjustment for multiple covariates, relative to participants in the U.S., systolic blood pressure was significantly higher among South Africans by 9.7 mmHg (p<0.05) and significantly lower for each of the other sites: viz, Jamaica, −7.9 mmHg (p=0.06), Ghana, −12.8 mmHg (p<0.01), Seychelles, −11.1 mmHg (p=0.01). Conclusion These data are consistent with prior findings of a blood pressure gradient in societies of the African diaspora and confirm that African-origin populations with lower social status in multi-racial societies, such as the US and South Africa, experience more hypertension than anticipated based on anthropometric and measurable socioeconomic risk factors.

    There are considerable racial disparities in prostate cancer risk, with a 60% higher incidence rate among African-American (AA) men compared with European-American (EA) men, and a 2.4-fold higher mortality rate in AA men than in EA men. Recently, studies have implicated several African-ancestry associated prostate cancer susceptibility loci on chromosome 8q24. In the current study, we performed admixture mapping in AA men from two independent case-control studies of prostate cancer to confirm the 8q24 ancestry association and also identify other genomic regions that may harbor prostate cancer susceptibility genes. A total of 482 cases and 261 controls were genotyped for 1,509 ancestry informative markers across the genome. The mean estimated individual admixture proportions were 20% European and 80% African. The most significant observed increase in European ancestry occurred at rs2141360 on chromosome 7q31 in both the case-only (P = 0.0000035) and case-control analyses. The most significant observed increase in African ancestry across the genome occurred at a locus on chromosome 5q35 identified by SNPs rs7729084 (case-only analysis P = 0.002), and rs12474977 (case-control analysis P = 0.004), which are separated by 646 kb and were adjacent to one another on the panel. On chromosome 8, rs4367565 was associated with the greatest excess African ancestry in both the case-only and case-control analyses (case-only and case-control P = 0.02), confirming previously reported African-ancestry associations with chromosome 8q24. In conclusion, we confirmed ancestry associations on 8q24, and identified additional ancestry-associated regions potentially harboring prostate cancer susceptibility loci.

    There is growing interest in exploring gene-environment interactions in the etiology of diseases in immigrants from sub-Saharan Africa. Our experience working with the Sudanese immigrant population in Omaha, NE, makes clear the pressing need for geneticists and federal and local funding agencies to address the ethical, legal and social implications of genetic research with such vulnerable populations. Our work raises several questions. How does one design research with African immigrant participants to assure it is ethical? Many immigrants may not understand the purposes, risks and benefits involved in research because of low literacy rates, one of the results of civil wars, or concepts of biologic science foreign to their cultures. Is it possible to obtain truly informed consent? Do African immigrants perceive genetic research using them as subjects as racist? Is genetic research on minorities "biopiracy" or "bio-colonialism?" In our experience, some Sudanese immigrants have challenged the legality and ethics of genetic studies with profit-making as an end. We have concluded that it is essential to educate African immigrant or any other non-English-speaking immigrant participants in research using lay language and graphic illustrations before obtaining consent. Cultural proficiency is important in gaining the trust of African immigrants; profit-sharing may encourage their participation in genetic research to benefit all; involvement of African immigrant community leaders in planning, delivery and evaluation using the community-based participatory research approach will facilitate healthcare promotion, health literacy education, as well as genetic research. It is crucial to address the ethical, legal and social implications of genetic studies with African immigrants as research subjects. PMID:18807438

  1. The Africanization of honeybees (Apis mellifera L.) of the Yucatan: a study of a massive hybridization event across time.

    2002-07-01

    Until recently, African and European subspecies of the honeybee (Apis mellifera L.) had been geographically separated for around 10,000 years. However, human-assisted introductions have caused the mixing of large populations of African and European subspecies in South and Central America, permitting an unprecedented opportunity to study a large-scale hybridization event using molecular analyses. We obtained reference populations from Europe, Africa, and South America and used these to provide baseline information for a microsatellite and mitochondrial analysis of the process of Africanization of the bees of the Yucatan Peninsula, Mexico. The genetic structure of the Yucatecan population has changed dramatically over time. The pre-Africanized Yucatecan population (1985) comprised bees that were most similar to samples from southeastern Europe and northern and western Europe. Three years after the arrival of Africanized bees (1989), substantial paternal gene flow had occurred from feral Africanized drones into the resident European population, but maternal gene flow from the invading Africanized population into the local population was negligible. However by 1998, there was a radical shift with both African nuclear alleles (65%) and African-derived mitochondria (61%) dominating the genomes of domestic colonies. We suggest that although European mitochondria may eventually be driven to extinction in the feral population, stable introgression of European nuclear alleles has occurred.

    Research indicates that engagement in community organizations is positively associated with health, particularly among aging populations, yet few studies have examined in detail the influence of community engagement (CE) on later health among African Americans. This study provides a longitudinal assessment of the effects of CE over a 22-year period on physical and mental health among a population of urban African American women. Data were from the Woodlawn Study, a prospective study of children and their families from an African American community in Chicago. Mothers who were assessed in 1975 and in 1997 reported involvement in religious and secular organizations. These reports were combined to create a five-category construct: no CE, early CE only, late CE only, persistent CE (either type at both assessments), and diverse and persistent CE (both types at both assessments). Multivariate regression analyses with multiple imputation (for N=680) estimated the impact of CE on four measures of physical and mental health: SF-36 physical functioning, self-rated health, anxious mood, and depressed mood. Women with late-only, persistent, and diverse and persistent CE reported significantly better health compared to non-involved women. Persistently engaged women were less likely to report anxious or depressed mood than those with early CE only. Persistent and diverse CE was more highly associated with better physical functioning than was persistent CE. Results highlight the strong positive link between health and concurrent, persistent, and diverse CE among African American women. PMID:21131117

    Objective To describe the baseline characteristics of the Primary Open-Angle African-American Glaucoma Genetics (POAAGG) study cohort, the largest African-American primary open-angle glaucoma (POAG) population recruited at a single institution (University of Pennsylvania, Department of Ophthalmology, Scheie Eye Institute) to date. Design Population-based, cross-sectional, case-control study. Participants 2,520 African-American subjects 35 years and older, recruited from the greater Philadelphia, Pennsylvania area. Methods Each subject underwent a detailed interview and eye examination. The interview assessed demographic, behavioral, medical, and ocular risk factors. Current zip codes surrounding the University of Pennsylvania were recorded and United States census data were queried to infer socioeconomic status. The eye exam included measurement of visual acuity and intraocular pressure, a detailed anterior and posterior segment examination including gonioscopy, dilated fundus and optic disc examination, visual fields, stereo disc photography, optical coherence tomography imaging, and measurement of central corneal thickness. Main Outcome Measures The baseline characteristics of gender, age, and glaucoma diagnosis were collected. Body mass index (BMI), hypertension, diabetes, and alcohol and tobacco use, as well as ocular conditions including blindness, cataract, non-proliferative diabetic retinopathy, age-related macular degeneration, and use of ocular medication and surgery, were examined. Median population density, income, education level, and other socioeconomic measures were determined for the study cohort. Results Of the 2,520 African-Americans recruited to the POAAGG study to date, 2,067 (82.0%) including 807 controls and 1,260 POAG cases met all inclusion criteria and completed the detailed clinical ocular exam. Cases were more likely to have a lower BMI (p<0.01) and report a history of blindness (visual acuity of 20/200 or worse, p<0.001), while controls

  1. Attrition biases in a study of Euro-American and African-American marriages.

    PubMed

    Oggins, Jean

    2004-06-01

    Based on survey data from 174 Euro-American and 199 African-American newlywed couples, this study analyzed attrition biases by comparing first-year responses of couples who stayed in the study into its third year (133 Euro-American and 115 African-American couples) with responses from the initial sample. Stayers--who were more likely than leavers to be better educated, wealthier, and Euro-American--tended to report happier, more affirming, more communicative marriages. For stayers, compared to a random subsample of the original sample, first-year marital happiness also correlated significantly less strongly with first-year reports of receiving affirmation from a spouse, having an unsupportive spouse, and engaging in marital conflict. Further, race differences in predictors of happiness for the initial sample were not evident among stayers, perhaps due to smaller variances in reported marital happiness and frequency of conflict for African-American stayers compared to African Americans in the original sample. Methodological implications for cross-cultural longitudinal studies are discussed.

    Epidemiologic studies on dementia generally have 2 major interacting objectives: descriptive, where rates of dementia and Alzheimer Disease (AD) are calculated for communities and selected populations, and analytic, which attempt to explain the observed phenotypic variations in communities and populations by identifying disease risk factors. The public health benefits derived from descriptive studies are exemplified by the recent published review of the global prevalence of dementia under the auspices of Alzheimer Disease International. This review emphasized the enormous and growing burden associated with dementia particularly for countries in the developing world and outlined strategies to influence policy making, planning, and healthcare allocation. One interesting feature of descriptive studies on dementia is that although the few epidemiologic studies conducted in Africa suggest that rates of dementia and AD are relatively low, rates of AD and dementia have been reported to be relatively high for African Americans. The Indianapolis-Ibadan Dementia Project has reported that the incidence rates for AD and dementia in Yoruba are less than half the incidence rates for AD and dementia in African Americans. Analytic studies are now underway to identify risk factors that may account for these rate differences. The risk factor model being applied, attempts to identify not only putative genetic and environmental factors but also their interactions. So far the major findings have included: apolipoprotein E e4, a major risk factor for AD in most populations, is also a risk factor for AD in African Americans but not for Yoruba; African Americans are at higher risk not only for AD, but also for diseases associated with increased cardiovascular risk such as hypertension, diabetes, and metabolic syndrome; African Americans have higher rates of hypercholesterolemia than Yoruba: there is an interaction between apolipoprotein E e4, cholesterol, and AD risk in both Yoruba and

    African-American men are disproportionately affected by preventable medical conditions, yet they underutilize primary care health services. Because healthcare utilization is strongly dependent on health beliefs, the purpose of this qualitative study was to identify and explore African-American men's perceptions of health and health influences. We conducted eight focus group interviews with select subgroups of African-American men, including adolescents, trauma survivors, HIV-positive men, homeless men, men who have sex with men, substance abusers, church-affiliated men and a mixed sample (N=71). Definitions of health, beliefs about health maintenance and influences on health were elicited. Participants' definitions of health went beyond the traditional "absence of disease" definition and included physical, mental, emotional, economic and spiritual well-being. Being healthy also included fulfilling social roles, such as having a job and providing for one's family. Health maintenance strategies included spirituality and self-empowerment. Stress was cited as a dominant negative influence on health, attributed to lack of income, racism, "unhealthy" neighborhoods and conflict in relationships. Positive influences included a supportive social network and feeling valued by loved ones. This study provides insight into African-American men's general health perceptions and may have implications for future efforts to improve healthcare utilization in this population.

    Furnham, Adrian; Callahan, Ines; Akande, Debo

    2004-05-01

    Black and White South Africans (n = 181) and Nigerians (n = 135) completed a questionnaire concerning the estimations of their own and their relatives' (father, mother, sister, brother) multiple intelligences as well as beliefs about the IQ concept. In contrast to previous results (A. Furnham, 2001), there were few gender differences in self-estimates. In a comparison of Black and White South Africans, it was clear the Whites gave higher estimates for self, parents, and brothers. However, overall IQ estimates for self and all relatives hovered around the mean of 100. When Black South Africans and Nigerians were compared, there were both gender and nationality differences on the self-estimates with men giving higher self-estimates than women and Nigerians higher self-estimates than South Africans. There were also gender and nationality differences in the answers to questions about IQ. The authors discuss possible reasons for the relatively few gender differences in this study compared with other studies as well as possible reasons for the cross-cultural difference.

    African-American men are disproportionately affected by preventable medical conditions, yet they underutilize primary care health services. Because healthcare utilization is strongly dependent on health beliefs, the purpose of this qualitative study was to identify and explore African-American men's perceptions of health and health influences. We conducted eight focus group interviews with select subgroups of African-American men, including adolescents, trauma survivors, HIV-positive men, homeless men, men who have sex with men, substance abusers, church-affiliated men and a mixed sample (N=71). Definitions of health, beliefs about health maintenance and influences on health were elicited. Participants' definitions of health went beyond the traditional "absence of disease" definition and included physical, mental, emotional, economic and spiritual well-being. Being healthy also included fulfilling social roles, such as having a job and providing for one's family. Health maintenance strategies included spirituality and self-empowerment. Stress was cited as a dominant negative influence on health, attributed to lack of income, racism, "unhealthy" neighborhoods and conflict in relationships. Positive influences included a supportive social network and feeling valued by loved ones. This study provides insight into African-American men's general health perceptions and may have implications for future efforts to improve healthcare utilization in this population. PMID:16623067

    Black and White South Africans (n = 181) and Nigerians (n = 135) completed a questionnaire concerning the estimations of their own and their relatives' (father, mother, sister, brother) multiple intelligences as well as beliefs about the IQ concept. In contrast to previous results (A. Furnham, 2001), there were few gender differences in self-estimates. In a comparison of Black and White South Africans, it was clear the Whites gave higher estimates for self, parents, and brothers. However, overall IQ estimates for self and all relatives hovered around the mean of 100. When Black South Africans and Nigerians were compared, there were both gender and nationality differences on the self-estimates with men giving higher self-estimates than women and Nigerians higher self-estimates than South Africans. There were also gender and nationality differences in the answers to questions about IQ. The authors discuss possible reasons for the relatively few gender differences in this study compared with other studies as well as possible reasons for the cross-cultural difference. PMID:15264443

    African-Americans with type 2 diabetes (T2DM) have higher morbidity and mortality partly attributed to poor glucose control and lack of formal diabetes self-management education and support (DSMES) programs compared to Whites. Therefore, the objective of this study was to compare the clinical and metabolic parameters during DSMES vs. standard care in African-Americans with T2DM attending primary care inner city clinics. We recruited 124 African-American patients with T2DM, randomized into Group 1-DSMES (n = 58) and Group 2-standard care group (n = 38) for 6 months. Body weight, blood pressure, random blood sugars and point-of-care (POC) hemoglobin A1C (A1C) and lipids/lipoproteins were measured at 0, 3, and 6 months. At 6 months, Group 1 had significant reduction in A1C (8.2 ± 1.4% vs. 7.5 ± 1.5%, p = 0.02) and random glucose (190.4 ± 77.6 vs. 160.6 ± 59.8 mg/dl, p = 0.03). However, there were no changes in body weight, blood pressure, or lipids/lipoprotein levels. We found no significant changes in the clinical/metabolic parameters in Group 2. We concluded that DSMES, supplemented with POC testing, was associated with significant improvements in glycemic control without changes in body weight, blood pressure, or lipids/lipoproteins. We recommend the inclusion of DSMES with POC testing in managing African-American patients with T2DM attending inner city primary care clinics.

    We analyze data from the South African Stress and Health Study, a nationally representative in-person psychiatric epidemiologic survey of 4,351 adults conducted as part of the World Mental Health Survey Initiative between January 2002 and June 2004. All blacks (Africans, Coloreds, and Indians) initially report higher levels of non-specific distress and anger/hostility than whites. Access to socioeconomic resources helps explain differences in non-specific distress between Coloreds and whites and Indians and whites. However, only when social stressors are considered do we find few differences in psychological distress (i.e., non-specific distress and anger/hostility) between Africans and whites. In addition, self-esteem and mastery have independent effects on non-specific distress and anger/hostility, but differences between Coloreds and whites in feelings of anger/hostility are not completely explained by self-esteem and mastery. The findings contribute to the international body of work on social stress theory, challenge underlying assumptions of the minority status perspective, and raise a series of questions regarding mental health disparities among South Africans.

    Genome-wide association studies (GWAS) in diverse populations are needed to reveal variants that are more common and/or limited to defined populations. We conducted a GWAS of breast cancer in women of African ancestry, with genotyping of > 1,000,000 SNPs in 3,153 African American cases and 2,831 controls, and replication testing of the top 66 associations in an additional 3,607 breast cancer cases and 11,330 controls of African ancestry. Two of the 66 SNPs replicated (p < 0.05) in stage 2, which reached statistical significance levels of 10−6 and 10−5 in the stage 1 and 2 combined analysis (rs4322600 at chromosome 14q31: OR = 1.18, p = 4.3×10−6; rs10510333 at chromosome 3p26: OR = 1.15, p = 1.5×10−5). These suggestive risk loci have not been identified in previous GWAS in other populations and will need to be examined in additional samples. Identification of novel risk variants for breast cancer in women of African ancestry will demand testing of a substantially larger set of markers from stage 1 in a larger replication sample.

    The heterosexual transmission of HIV has affected middle-age African American women at alarming rates; yet there is a paucity of research and interventions focused on this population. This study used a qualitative approach to understand middle-age urban African American women’s experiences with HIV-related sexual risk behaviors and to identify the sexual protective strategies they employed to reduce their risk for HIV infection. Ten African American women, ages 45 to 56, were recruited from low-income neighborhoods in New York City. Data were collected using in-depth interviews and analyzed using content analysis. Investigator triangulation and member checking were used to ensure rigor. Five salient themes emerged that highlighted the individual, gender/relationship power factors, and the sociocultural elements that influenced sexual protection or risk-taking behavior. Findings provide new insight into the complexities of HIV sexual risk behavior and can guide future HIV prevention interventions for middle-age, African American, urban women. PMID:26194973

    Concurrent validation procedures were employed, using a sample of African American precollege students, to determine the extent to which scale scores obtained from the first edition of the Learning and Study Strategies Inventory (LASSI) were appropriate for diagnostic purposes. Data analysis revealed that 2 of the 10 LASSI scales (i.e., Anxiety and Test Strategies) significantly correlated with a measure of academic ability. These results suggested that scores obtained from these LASSI scales may provide valid assessments of African American precollege students’ academic aptitude. Implications for teachers, school counselors, and developmental studies professionals were discussed. PMID:22454973

    Low-grade inflammation has been correlated with risk factors of cardiovascular diseases (CVD). Whether the pro-inflammatory and thrombotic ratio (fibrosis) may contribute to CVD is not known. We therefore aimed to assess whether Cornell Product left ventricular hypertrophy (LVH) is associated with fibrosis and coronary perfusion (silent ischemia) in a bi-ethnic male cohort from South Africa. A cross sectional study was conducted including 165 African and Caucasian men between the ages of 20-65. Fasting blood samples were obtained to measure fibrinogen, C-reactive protein (CRP), interleukin-6 (IL-6), and tumor necrosis factor (TNF-α). Ambulatory blood pressure, ECG and 12 lead ECG measures were obtained to determine silent ischemic events (ST events) and LVH, respectively. Africans revealed more silent ischemia, higher 24 h blood pressure, inflammatory, coagulation as well as fibrosis levels than Caucasians. In a low-grade inflammatory state (CRP > 3 mg/l), Africans revealed higher fibrosis (p ≤ 0.01) values, but lower IL-6 and TNF-α values than Caucasians. Linear regression analyses in several models demonstrated positive associations between silent ischemia and fibrosis [Adj. R(2) 0.23; ß 0.35 (95% CI 0.13, 0.58), p ≤ 0.01]. In a low-grade inflammatory state (CRP>3mg/l), fibrinogen predicted AV-block in African men [OR 3.38 (95% CI 2.24, 4.53); p = 0.04]. Low-grade inflammation may induce AV-block through mechanisms involving fibrosis and ischemia to increase the burden on the heart in African men. PMID:27380493

    We have discovered a possible "natural fueling" mechanism in tokamak fusion reactors using large scale gyrokinetic turbulence simulation. In the presence of a heat flux dominated tokamak plasma, cold ions naturally pinch radially inward. If cold DT fuel is introduced near the edge using shallow pellet injection, the cold fuel will pinch inward, at the expense of hot helium ash going radially outward. By adjusting the cold DT fuel concentration, the core DT density profiles can be maintained. We have also shown that cold source ions from edge recycling of cold neutrals are pinched radially inward. This mechanism may be important for fully understanding the edge pedestal buildup after an ELM crash. Work includes benchmarking the gyrokinetic turbulence codes in the electromagnetic regime. This includes cyclone base case parameters with an increasing plasma beta. The code comparisons include GEM, GYRO and GENE. There is good linear agreement between the codes using the Cyclone base case, but including electromagnetics and scanning the plasma beta. All the codes have difficulty achieving nonlinear saturation as the kinetic ballooning limit is approached. GEM does not saturate well when beta gets above about 1/2 of the ideal ballooning limit. We find that the lack of saturation is due to the long wavelength k{sub y} modes being nonlinearly pumped to high levels. If the fundamental k{sub y} mode is zeroed out, higher values of beta nonlinearly saturate well. Additionally, there have been studies to better understand CTEM nonlinear saturation and the importance of zonal flows. We have continued our investigation of trapped electron mode (TEM) turbulence. More recently, we have focused on the nonlinear saturation of TEM turbulence. An important feature of TEM is that in many parameter regimes, the zonal flow is unimportant. We find that when zonal flows are unimportant, zonal density is the dominant saturation mechanism. We developed a simple theory that agrees with the

    Background As part of the planning process for new research, the literature on community-based participatory research (CBPR) approaches for promoting physical activity in African American communities was systematically reviewed. Methods Studies published through October 31, 2015 that employed CBPR methods were identified using PubMed and CINAHL databases and MeSH terms and keyword searches. Results A total of 15 studies met the search criteria. One focused on CBPR and physical activity among African American school children and adolescents, 13 on adults, and one on both children and adults. Seven studies employed CBPR methods to promote physical activity in church settings. Eight of the studies had a pre-/post-test design, three had a quasi-experimental design, three had a randomized controlled design, and one was a case study. Conclusions Additional CBPR studies and faith-based interventions are needed to identify effective ways to promote physical activity in African American communities to address health disparities. Of particular interest are those that have an adequate sample size and a rigorous design, to overcome limitations of previous studies. PMID:27034993

    The metabolic syndrome (MetS) is a constellation of metabolic disorders that increase the risk of developing several diseases including type 2 diabetes and cardiovascular diseases. Although genome-wide association studies (GWAS) have successfully identified variants associated with individual traits comprising MetS, the genetic basis and pathophysiological mechanisms underlying the clustering of these traits remain unclear. We conducted GWAS of MetS in 1427 Africans from Ghana and Nigeria followed by replication testing and meta-analysis in another continental African sample from Kenya. Further replication testing was performed in an African American sample from the Atherosclerosis Risk in Communities (ARIC) study. We found two African-ancestry specific variants that were significantly associated with MetS: SNP rs73989312[A] near CA10 that conferred increased risk (P=3.86 × 10(-8), OR=6.80) and SNP rs77244975[C] in CTNNA3 that conferred protection against MetS (P=1.63 × 10(-8), OR=0.15). Given the exclusive expression of CA10 in the brain, our CA10 finding strengthens previously reported link between brain function and MetS. We also identified two variants that are not African specific: rs76822696[A] near RALYL associated with increased MetS risk (P=7.37 × 10(-9), OR=1.59) and rs7964157[T] near KSR2 associated with reduced MetS risk (P=4.52 × 10(-8), Pmeta=7.82 × 10(-9), OR=0.53). The KSR2 locus displayed pleiotropic associations with triglyceride and measures of blood pressure. Rare KSR2 mutations have been reported to be associated with early onset obesity and insulin resistance. Finally, we replicated the LPL and CETP loci previously found to be associated with MetS in Europeans. These findings provide novel insights into the genetics of MetS in Africans and demonstrate the utility of conducting trans-ethnic disease gene mapping studies for testing the cosmopolitan significance of GWAS signals of cardio-metabolic traits.

    Diabetes is one of the most common metabolic disorders worldwide. It is a major health problem with its frequency increasing every day in most countries. The disease is generally believed to be incurable; and the few orthodox drugs available to manage the disease are not readily affordable to the poor. Based on the historical success of natural products as antidiabetic agents and the ever increasing need for new antidiabetics, a number of South African medicinal plants have been evaluated for their antidiabetic properties. In this article, we review the major studies conducted based on ethnobotanical surveys carried out between 2005 and 2008 in South Africa on plants that are traditionally used for the treatment of diabetes. Overall, the results of the studies conducted confirmed the potential of South African medicinal plants in antidiabetic drug discovery and identified a number of promising taxa for further in vivo investigation as plant-based antidiabetic agents.

    Spirituality and religion have been identified as important determinants of health for adults; however, the impact of faith-oriented factors on health behaviors and outcomes among African American adolescent males has not been well studied. The purpose of this study is to examine the relationship between religiosity and spirituality and obesity-related behaviors among 12-19 year old African American males (N = 105) in the Jackson Heart KIDS Pilot Study. Key variables of interest are church attendance, prayer, daily spirituality, weight status, attempts to lose weight, nutrition, physical activity, and stress. Daily spirituality is associated with whether an individual attempts to lose weight. The results from logistic regression models suggest that daily spirituality increases the odds that African American male adolescents attempt to lose weight (OR = 1.22, CI: 1.07-1.41) and have a history of diet-focused weight management (OR = 1.13, CI: 1.02-1.26). Future studies are needed to further explore the association between religion, spirituality, and obesity-related behaviors.

    Background Colorectal cancer (CRC) is the third leading cause of cancer-related deaths in the United States. Although studies have been performed on malignancy behavior in African Americans and Caucasians, scant data are present on other minority racial groups. Methods A retrospective single center study was performed where 1,860 patient charts with a diagnosis of CRC from January 1, 2004 to December 31, 2014 were reviewed. Data collected on each patient included age, gender, ethnicity, primary site and histological stage at the time of diagnosis. Survival time over the course of 5 years was documented for patients from January 1, 2004 to December 31, 2009. Comparisons were made amongst different racial groups for the above mentioned factors. Results Study population consisted of 27.09% African Americans, 65.61% Caucasians, 3.86% Hispanics, 0.54% South Asians, 1.03% Arabs, 0.54% Asians and 0.22% American Indians. Mean age of CRC presentation was found to be significantly different (P < 0.05) between the three largest racial groups: 71 years for Caucasians, 69 years for African Americans, and 61 years for Hispanics. African Americans (27.09%) and Hispanics (28.79%) presented predominantly at stage IV in comparison to other racial groups. Caucasians presented predominantly at stage III (24.84%). The rectum was the most common site of CRC across all racial groups with the exception of Asians, where sigmoid colon was the predominant site (30%). Adenocarcinoma remained the predominant cancer type in all groups. Hispanics had relatively higher incidence rate of carcinoid tumor (12.68%). Survival time analysis showed that Caucasians tend to have better survival probability over 5 years after initial diagnosis as compared to African Americans and Hispanic (P < 0.05). Conclusion There is lack of studies performed on minority racial groups in North America. Our study highlighted some important clinical differences of CRC presentation in different racial groups which are not

    Exposure to racism has been linked to poor health outcomes. Little is known about the impact of racism on diabetes outcomes. This study explored African American women's beliefs about how racism interacts with their diabetes self-management and control. Four focus groups were conducted with a convenience sample of 28 adult African American women with type 2 diabetes who were recruited from a larger quantitative study on racism and diabetes. The focus group discussions were transcribed verbatim and analyzed by the authors. Women reported that exposure to racism was a common phenomenon, and their beliefs did in fact link racism to poor health. Specifically, women reported that exposure to racism caused physiological arousal including cardiovascular and metabolic perturbations. There was consensus that physiological arousal was generally detrimental to health. Women also described limited, and in some cases maladaptive, strategies to cope with racist events, including eating unhealthy food choices and portions. There was consensus that the subjective nature of perceiving racism and accompanying social prohibitions often made it impossible to address racism directly. Many women described anger in such situations and the tendency to internalize anger and other negative emotions, only to find that the negative emotions would be reactivated repeatedly with exposure to novel racial stressors, even long after the original racist event remitted. African American women in this study believed that racism affects their diabetes self-management and control. Health beliefs can exert powerful effects on health behaviors and may provide an opportunity for health promotion interventions in diabetes.

    Intuitive Eating programs that improve self-efficacy and dietary habits could enhance glycemic control in African-American women with type 2 diabetes. The goal of this study was to investigate how current eating practices and beliefs of African-American women living with diabetes aligned with intuitive eating concepts. African-American women with type 2 diabetes referred for diabetes education class in 2009–2012 were recruited for a qualitative study using focus groups for data collection. Verbatim group transcriptions were analyzed by two independent reviewers for themes using a combined inductive-deductive approach. Participants (n=35) had an average age of 52±9 years, mean body mass index of 39±7, and mean time with a type 2 diabetes diagnosis of 10±10 years. Participants’ self-reported dietary practices were poorly aligned with intuitive eating concepts. The women reported a lack of self-control with food and regularly eating in the absence of hunger, yet stated that the determinant factor for when to stop eating was to recognize a feeling of fullness. Participants reported knowing they were full when they felt physically uncomfortable or actually became sick. Women frequently cited the belief that individuals with diabetes have to follow a different diet than that recommended for the general public. Many women also discussed diabetes-related stigma from family/friends, and often did not tell others about their diabetes diagnosis. These findings demonstrate that intuitive eating techniques are not currently applied by the women in this sample. Future studies should assess the impact of intuitive eating interventions on dietary habits among low-income African-American women with type 2 diabetes. PMID:24699138

    We examined the feasibility and acceptability of an HIV prevention intervention for African American adolescents delivered via mobile cell phones and looked at intervention-related changes in beliefs and sexual behaviors. We used a longitudinal one-group comparison design with data collected at three points. Forty adolescents, 13–18 years old, participated in the Becoming a Responsible Teen intervention followed by the delivery of daily multimedia messages for 3 months. The mobile-cell-phone enhanced intervention was feasible and acceptable to the participants. Greater HIV knowledge, improved attitudes toward condoms, and increased perceived HIV risk scores were observed with older adolescents (16–18 years old). Behavior trends showed a decrease in the number of times participants reported engaging in unprotected sexual intercourse over the previous 2 months. Mobile-cell-phone multimedia-text-messaging boosters tested in this study provided preliminary evidence of efficacy of the enhanced HIV prevention intervention for African American youth.

    This study investigated the association between religious involvement and major depression in 607 African American adults, using longitudinal data from the National Survey of Black Americans. Logistic regression found that survey participants who reported receiving "a great deal" of guidance from religion in their day-to-day lives at Time 1 (1988-1989) were roughly half as likely (OR = 0.47, p < 0.01) to have major depression at Time 2 (1992), controlling for sociodemographic and psychological factors, and major depression at baseline. The odds of major depression were also lower for persons with high self-esteem (OR = 0.41, p < 0.01) and those who reported having satisfying relationships with friends and family members (OR = 0.51, p < 0.05) at baseline. No association was found between religious attendance or church support and major depression. The possible mechanisms through which religious involvement may protect against depression, especially among African Americans, are discussed.

    Adapting to an over-demanding stressful urban environment may exhaust the psychophysiological resources to cope with these demands, and lead to sympathetic nervous system dysfunction. The evidence that an urban-dwelling lifestyle may be detrimental to the cardiometabolic health of Africans motivated the design of the Sympathetic activity and Ambulatory Blood Pressure in African Prospective cohort study. We aimed to determine neural mechanistic pathways involved in emotional distress and vascular remodelling. The baseline sample included 409 teachers representing a bi-ethnic sex cohort from South Africa. The study was conducted in 2008–09 and repeated after 3-year follow-up in 2011–12, with an 87.8% successful follow-up rate. Seasonal changes were avoided and extensive clinical assessments were performed in a well-controlled setting. Data collection included sociodemographics, lifestyle habits, psychosocial battery and genetic analysis, mental stress responses mimicking daily life stress (blood pressure and haemostatic, cardiometabolic, endothelial and stress hormones). Target organ damage was assessed in the brain, heart, kidney, blood vessels and retina. A unique highly phenotyped cohort is presented that can address the role of a hyperactive sympathetic nervous system and neural response pathways contributing to the burden of cardiometabolic diseases in Africans.

    2003-01-01

    BACKGROUND: Electrocardiographic (ECG) differences occur between African-American and white persons. METHODS: Intraventricular conduction abnormalities of ECGs of 2,123 African-American and white hospital patients ages 20-99 years were studied in a consecutive manner. RESULTS: Intraventricular conduction abnormalities develop later in life and are less common in African-American patients, compared with white patients. The prevalence of conduction abnormalities increases with advancing age in both races. Left- and right ventricular conduction abnormalities begin to rise at age 50 for white patients but begin to rise at age 70 for African-American patients. The prevalence of left ventricular conduction abnormalities peaks in the ninth decade of life in both races but declines in both races in the tenth decade of life. The prevalence of right ventricular conduction abnormalities gradually increases and peaks in the tenth decade of life in both races. CONCLUSIONS: The prevalence of intraventricular block is significantly less in African-American patients, compared with white patients--occurring in 8.6% of African-American patients and in 15.2% of white patients. The prevalence of intraventricular block is lowest in African-American women at 6.5% and highest in white men at 16.8%. PMID:14527049

  7. As I see it: a study of African American pastors' views on health and health education in the black church.

    The Black Church is the only institution that has consistently served the interest of African Americans, and there is no other institution in the African American community that rivals its influence (Camara, 2004). The spiritual well-fare, social support, health, and well-being of its people have been one of its main goals. With health disparities of African Americans still at an alarming rate, the Black Church has used informal education as a means to impart knowledge on health, as well as other non-religious and religious topics. One of the avenues least researched within the Black Church is the pastor's perception of its educational role in health and wellness and its efforts to reduce health discrimination and health disparities between African American and European Americans in the U.S. Since social justice appears as a theme and concern in the traditions of many churches, it is only appropriate that, among other things, the Black Church should address the issue of health education and interventions. The purpose of this study was to explore African American pastors' perceptions of the role of the Black Church in providing health care, health education, and wellness opportunities to African Americans. Many pastors reported their church provided some form of health education and/or health screenings. Their perceptions about the important issues facing their congregants versus African Americans in general were quite similar.

    This study reports findings on views of masculinity with undergraduate Black men, which included interviews and focus groups (N = 46) with participants ranging in age from 18 to 22 years. Specifically, this study explored how Black men define being a man and being a Black man. Undergraduate Black males at a historically Black college and university (N = 25) and a predominately White institution (N = 21) in the Southeastern United States were recruited to participate in this study. Through the use of thematic analysis, findings indicated that three levels of masculinity exist for Black men: what it means to be a man, what it means to be a Black man, and who influences male development. Implications and recommendations for future research and practice are discussed.

    According to the Centers for Disease Control and Prevention (2013), African Americans have a substantially greater prevalence of a range of health conditions when compared to other racial or ethnic groups. Many of these conditions have been attributed to the historical and contemporary social and economic disparities faced by the African American community. While many health conditions occur at a higher rate in African Americans, it is unclear whether there are specific symptom clusters that may also be more prevalent in African Americans as a result of these disparities. Potential differences in symptomology have not been thoroughly examined between African Americans and White populations. The current study compares the prevalence and pain severity of symptoms among a sample of African Americans and White participants. Significant differences in symptom prevalence were found in disturbed sleep and reproductive areas. African Americans also experience more pain due to symptoms related to orthostatic intolerance. Implications of this finding are discussed.

    Nonshaved neurosurgery, cranial or spinal, is well reported among Caucasians but hardly among native Africans. The ungroomed scalp hairs of black Africans have unique anthropological characteristics needing special attention for shaveless cranial surgery. A technical report of the execution of this surgical procedure among an indigenous patient population in a sub-Sahara African country is presented, as well as an outcome analysis in a prospective cohort over a 7-year period. A total of 303 patients (211 males, 70 %) fulfilled the criteria for this study. The surgical procedure was primary in 278 (92 %) and redo in 8 %. It was emergency surgery in 153 (51 %). They were trauma craniotomies or decompressive craniectomies in 95 cases (31 %), craniotomies for tumour resections in 86 (28 %), and the surgical dissections for other conditions in 122 (41 %). The duration of surgery ranged from 30 min to 8.5 h, mean 2.5 (SD, 1.6), median 2. In-hospital clinical outcome was good (normal status or moderate deficit on dichotomized Glasgow outcome scale (GOS)) in 273 (90.1 %) cases while surgical site infections occurred in only 10 cases (3.3 %). The type of surgery, redo or primary, did not have any significant association with the in-hospital outcome (p = 0.5), nor with the presence of surgical site infection (SSI) (p = 0.7). The length of follow-up ranged from 2 to 63 months (mean, 7) with no untoward complications reported so far. Medium-term outcome of nonshaved neurosurgery in this indigenous black Africans remains favourable with no attendant significant adverse after-effects. PMID:26873745

    African Americans and overweight or obese women are at increased risk for excessive gestational weight gain (GWG) and postpartum weight retention. Interventions are needed to promote healthy GWG in this population; however, research on exercise and nutritional barriers during pregnancy in African American women is limited. The objective of this qualitative study is to better inform intervention messages by eliciting information on perceptions of appropriate weight gain, barriers to and enablers of exercise and healthy eating, and other influences on healthy weight gain during pregnancy in overweight or obese African American women. In-depth interviews were conducted with 33 overweight or obese African American women in Columbia, South Carolina. Women were recruited in early to mid-pregnancy (8-23 weeks gestation, n = 10), mid to late pregnancy (24-36 weeks, n = 15), and early postpartum (6-12 weeks postpartum, n = 8). Interview questions and data analysis were informed using a social ecological framework. Over 50 % of women thought they should gain weight in excess of the range recommended by the Institute of Medicine. Participants were motivated to exercise for personal health benefits; however they also cited many barriers to exercise, including safety concerns for the fetus. Awareness of the maternal and fetal benefits of healthy eating was high. Commonly cited barriers to healthy eating include cravings and availability of unhealthy foods. The majority of women were motivated to engage in healthy behaviors during pregnancy. However, the interviews also uncovered a number of misconceptions and barriers that can serve as future intervention messages and strategies. PMID:22527762

    African animal trypanosomosis is a parasitic blood disease transmitted by tsetse flies and is widespread in sub-Saharan Africa. West African taurine breeds have the ability, known as trypanotolerance, to limit parasitaemia and anaemia and remain productive in enzootic areas. Several quantitative trait loci (QTL) underlying traits related to trypanotolerance have been identified in an experimentally infected F(2) population resulting from a cross between taurine and zebu cattle. Although this information is highly valuable, the QTL remain to be confirmed in populations subjected to natural conditions of infection, and the corresponding regions need to be refined. In our study, 360 West African cattle were phenotyped for the packed cell volume control under natural conditions of infection in south-western Burkina Faso. Phenotypes were assessed by analysing data from previous cattle monitored over 2 years in an area enzootic for trypanosomosis. We further genotyped for 64 microsatellite markers mapping within four previously reported QTL on BTA02, BTA04, BTA07 and BTA13. These data enabled us to estimate the heritability of the phenotype using the kinship matrix between individuals computed from genotyping data. Thus, depending on the estimators considered and the method used, the heritability of anaemia control ranged from 0.09 to 0.22. Finally, an analysis of association identified an allele of the MNB42 marker on BTA04 as being strongly associated with anaemia control, and a candidate gene, INHBA, as being close to that marker.

    This study assessed the feasibility of recruiting African American men in barbershops, assessing their physical activity, conducting physical measurements, and gauging their interest in barbershop-based health research. The authors recruited African American shop owners (n = 4), barbers (n = 6), and customers (n = 90) from four barbershops in Raleigh and Durham, North Carolina, during 2009. The participation levels were high among owners (100%), barbers (67%), and customers (81%). In addition to completing a self-administered survey, 57% (51/90) of the customers completed physical measurements. According to self-reported data, 34% (30/88) of the customers met national physical activity recommendations within the last week. Customers expressed moderately high interest in learning more about health at barbershops and joining a barbershop-based physical activity contest. The estimated recruiting cost per customer was $105.92. Barbershops offer an effective setting for recruiting African American men and conducting physical measurements as well as an interesting possible location for conducting future interventions.

    Aeolian African dust from the Saharan-Sahel deserts significantly influences the climate and ecology of the Caribbean region. Large summer dust storms produce mass quantities of air-born, clay-rich material (containing significant iron-oxide components), that are transported over the Atlantic Ocean and deposited in the Caribbean. We present here the results of a rock magnetic study of cores of Scleractinian corals, including a Montastraea annularis collected in Culebra, Puerto Rico on July of 1991, a M. faveolata collected off the coast of St. Vincent (Bequia) on November of 2002, and a Siderastrea radians collected off the coast of Cape Verde on July of 2002. Thin slabs (~5mm) were cut from these cores and x-rayed to reveal annual density banding. Small samples centered over each annual high-density band were cut from the slabs. These samples were then subjected to a series of standard rock magnetic experiments, including Anhysteretic Remanent Magnetization (ARM) acquisition and demagnetization, and Isothermal Remanent Magnetization (IRM) acquisition and demagnetization. Records of both ARMs and IRMs reveal coherent signals that vary with coral age. The IRM acquisition curves demonstrate the presence of two carriers of magnetization in most samples; a low-coercivity component consistent with the presence of magnetite or maghemite and a high-coercivity component consistent with the presence of hematite. Unmixing the IRM acquisition curves differentiates the magnetic components and yields a record of high-coercivity input that we interpret as a record of African dust. Preliminary data from the M. annularis core show a link between high and low variability in the high-coercivity component when compared with the historical record of dust flux to the Caribbean and with the Soudano-Sahel Precipitation Index (SSPI) over a time period of fifty years (1941-1990). High variability is displayed from 1941 through 1950 and 1965 through 1990 whereas low variability is displayed

    Remote sensing offers a cost efficient means for identifying and monitoring wetlands over a large area and at different moments in time. In this study, we aim at providing ecologically relevant information on characteristics of temporary and permanent isolated open water wetlands, obtained by standard techniques and relatively cheap imagery. The number, surface area, nearest distance, and dynamics of isolated temporary and permanent wetlands were determined for the Western Cape, South Africa. Open water bodies (wetlands) were mapped from seven Landsat images (acquired during 1987 – 2002) using supervised maximum likelihood classification. The number of wetlands fluctuated over time. Most wetlands were detected in the winter of 2000 and 2002, probably related to road constructions. Imagery acquired in summer contained fewer wetlands than in winter. Most wetlands identified from Landsat images were smaller than one hectare. The average distance to the nearest wetland was larger in summer. In comparison to temporary wetlands, fewer, but larger permanent wetlands were detected. In addition, classification of non-vegetated wetlands on an Envisat ASAR radar image (acquired in June 2005) was evaluated. The number of detected small wetlands was lower for radar imagery than optical imagery (acquired in June 2002), probably because of deterioration of the spatial information content due the extensive pre-processing requirements of the radar image. Both optical and radar classifications allow to assess wetland characteristics that potentially influence plant and animal metacommunity structure. Envisat imagery, however, was less suitable than Landsat imagery for the extraction of detailed ecological information, as only large wetlands can be detected. This study has indicated that ecologically relevant data can be generated for the larger wetlands through relatively cheap imagery and standard techniques, despite the relatively low resolution of Landsat and Envisat imagery

    The predictive effects of age and self-rated health (SRH) on all-cause mortality are known to differ across race and ethnic groups. African American adults have higher mortality rates than Whites at younger ages, but this mortality disparity diminishes with advancing age and may "crossover" at about 75-80 years of age, when African Americans may show lower mortality rates. This pattern of findings reflects a lower overall association between age and mortality for African Americans than for Whites, and health-related mechanisms are typically cited as the reason for this age-based crossover mortality effect. However, a lower association between poor SRH and mortality has also been found for African Americans than for Whites, and it is not known if the reduced age and SRH associations with mortality for African Americans reflect independent or overlapping mechanisms. This study examined these two mortality predictors simultaneously in a large epidemiological study of 12,181 African Americans and 17,436 Whites. Participants were 45 or more years of age when they enrolled in the national REasons for Geographic and Racial Differences in Stroke (REGARDS) study between 2003 and 2007. Consistent with previous studies, African Americans had poorer SRH than Whites even after adjusting for demographic and health history covariates. Survival analysis models indicated statistically significant and independent race*age, race*SRH, and age*SRH interaction effects on all-cause mortality over an average 9-year follow-up period. Advanced age and poorer SRH were both weaker mortality risk factors for African Americans than for Whites. These two effects were distinct and presumably tapped different causal mechanisms. This calls into question the health-related explanation for the age-based mortality crossover effect and suggests that other mechanisms, including behavioral, social, and cultural factors, should be considered in efforts to better understand the age-based mortality

    Recent studies show widespread encroachment of forest into savannas with important consequences for the global carbon cycle and land-atmosphere interactions. However, little research has focused on in situ measurements of the successional sequence of savanna to forest in Africa. Using long-term inventory plots we quantify changes in vegetation structure, above-ground biomass (AGB) and biodiversity of trees ≥10 cm diameter over 20 years for five vegetation types: savanna; colonising forest (F1), monodominant Okoume forest (F2); young Marantaceae forest (F3); and mixed Marantaceae forest (F4) in Lopé National Park, central Gabon, plus novel 3D terrestrial laser scanning (TLS) measurements to assess forest structure differences. Over 20 years no plot changed to a new stage in the putative succession, but F1 forests strongly moved towards the structure, AGB and diversity of F2 forests. Overall, savanna plots showed no detectable change in structure, AGB or diversity using this method, with zero trees ≥10 cm diameter in 1993 and 2013. F1 and F2 forests increased in AGB, mainly as a result of adding recruited stems (F1) and increased Basal Area (F2), whereas F3 and F4 forests did not change substantially in structure, AGB or diversity. Critically, the stability of the F3 stage implies that this stage may be maintained for long periods. Soil carbon was low, and did not show a successional gradient as for AGB and diversity. TLS vertical plant profiles showed distinctive differences amongst the vegetation types, indicating that this technique can improve ecological understanding. We highlight two points: (i) as forest colonises, changes in biodiversity are much slower than changes in forest structure or AGB; and (ii) all forest types store substantial quantities of carbon. Multi-decadal monitoring is likely to be required to assess the speed of transition between vegetation types. PMID:27336632

    Establishing a holistic approach for the enrollment of subjects into clinical trials that includes strategies for the recruitment of non-traditional and minority populations has been an elusive task. The existence of such a design, that is understood and embraced by investigators and the target communities, would streamline the current level of commitment of time, energy and resources. This is necessary to successfully encourage individual and community participation in research studies. The Center for Research in Reproduction at Meharry set out to recruit a large number of African American women volunteers of reproductive age into clinical trials. The experience, of recruiting volunteers from the African American community for clinical trials in the Meharry Medical College/Pennsylvania State University (MMC/PSU)'s Cooperative Center for Research in Reproduction at Meharry, is presented.

    Few studies have examined depression among immigrants in post-apartheid South Africa, and factors that strengthen the relationship between immigration and depression. The first wave of the National Income Dynamics Study was used to investigate links between immigration and depression (n = 15,205). Depression symptoms were assessed using a 10-item version of the Center for Epidemiologic Studies Depression (CES-D) Scale. Immigrants in South Africa had fewer depressive symptoms (CES-D ≥ 10) than locally-born participants (17.1 vs. 32.4%, F = 13.5, p < 0.01). Multilevel mixed-effects logistic regression analyses found that among immigrant populations, younger age (adjusted OR 1.03, 95% CI 1.01-1.05) and black African ethnicity (adjusted OR 3.72, 95% CI 1.29-10.7) were associated with higher depression. Younger age was associated with lower depression among locally-born study participants (adjusted OR 0.98, 95% CI 0.97-0.98). The varying relationship between certain demographic factors, depression and the different mental health challenges among these groups requires closer attention.

    Objective Suicide and suicidal behaviours are significant public health problems and a leading cause of death worldwide and in South Africa. We examined the association between childhood adversities and suicidal behaviour over the life course. Methods A national probability sample of 4351 South African adult participants (aged 18 years and older) in the South African Stress and Health (SASH) study was interviewed as part of the World Mental Health Surveys initiative. Respondents provided sociodemographic and diagnostic information, as well as an account of suicide-related thoughts and behaviours. Suicidality or suicidal behaviour were defined as were defined as suicide attempts and suicidal ideation in the total sample, and suicide plans and attempts among ideators. Childhood adversities included physical abuse, sexual abuse, parental death, parental divorce, other parental loss, family violence, physical illness and financial adversity. The association between suicidality and childhood adversities was examined using discrete-time survival models. Results More than a third of the respondents with suicidal behaviour experienced at least one childhood adversity, with physical abuse, parental death and parental divorce being the most prevalent adversities. Physical abuse, sexual abuse and parental divorce were identified as significant risk markers for lifetime suicide attempts, while physical abuse and parental divorce were significantly correlated with suicidal ideation. Two or more childhood adversities were associated with a twofold higher risk of lifetime suicide attempts. Sexual abuse (OR 9.3), parental divorce (OR 3.1) and childhood physical abuse (OR 2.2) had the strongest associations with lifetime suicide attempts. The effect of childhood adversities on suicidal tendencies varied over the life course. For example, sexual abuse was significantly associated with suicide attempts during childhood and teen years, but not during young and later adulthood

    BACKGROUND AND PURPOSE Rates of type 2 diabetes are higher among African Americans compared with individuals of European ancestry. The purpose of this investigation was to determine the relationship between MR imaging measures of brain structure (volume of GM, WM, WM lesions) and cognitive function in a population of African Americans with type 2 diabetes. These MR imaging measures of brain structure are affected by type 2 diabetes–associated macrovascular and microvascular disease and may be associated with performance on tasks of cognitive function in the understudied African American population. MATERIALS AND METHODS African Americans with type 2 diabetes enrolled in the African American–Diabetes Heart Study MIND study (n = 263) were evaluated across a broad range of cognitive domains and imaged with brain MR imaging. Associations between cognitive parameters and MR imaging measures of whole-brain GM, WM, and WM lesion volumes were assessed by using adjusted multivariate models. RESULTS Lower GM volume was associated with poorer performance on measures of general cognitive function, working memory, and executive function. Higher WM lesion volume was associated with poorer performance on a smaller subset of cognitive domains compared with GM volume but included aspects of working memory and executive function. There were no statistically significant associations with WM volume. CONCLUSIONS Markers of cortical atrophy and WM lesion volume are associated with cognitive function in African Americans with type 2 diabetes. These associations are described in an African American cohort with disease control similar to that of individuals of European ancestry, rather than underserved African Americans with poor access to health care. Interventions to reduce cortical atrophy and WM disease may improve cognitive outcomes in this understudied population. PMID:26206811

  5. Photosynthetic reaction center of green sulfur bacteria studied by EPR

    Membrane preparations of two species of the green sulfur bacteria Chlorobium have been studied be EPR. Three signals were detected which were attributed to iron-sulfur centers acting as electron acceptors in the photosynthetic reaction center. (1) A signal from a center designated F{sub B}, was photoinduced at 4K. (2) A similar signal, F{sub A}, was photoinduced in addition to the F{sub B} signal upon a short period of illumination at 200 K. (3) Further illumination at 200 K resulted in the appearance of a broad feature at g=1.78. This is attributed to the g{sub x} component of an iron-sulfur center designated F{sub X}. The designations of these signals as F{sub B}, F{sub A}, and F{sub X} are based on their spectroscopic similarities to signals in photosystem I (PS I). The orientation dependence of these EPR signals in ordered Chlorobium membrane multilayers is remarkably similar to that of their PS I homologues. A magnetic interaction between the reduced forms of F{sub B} and F{sub A} occurs, which is also very similar to that seen in PS I. The triplet state of P{sub 840}, the primary electron donor, could be photoinduced at 4 K in samples which had been preincubated with sodium dithionite and methyl viologen and then preilluminated at 200 K. The preillumination reduces the iron-sulfur centers while the preincubation is thought to result in the inactivation of an earlier electron acceptor. Orientation studies of the triplet signal in ordered multilayers indicate that the bacteriochlorophylls which act as the primary electron donor in Chlorobium are arranged with a structural geometry almost identical with that of the special pair in purple bacteria. The Chlorobium reaction center appears to be similar in some respects to both PS I and to the purple bacterial reaction center. This is discussed with regard to the evolution of the different types of reaction centers from a common ancestor.

  8. A study of the lived experiences of African American women STEM doctoral degree completers

    NASA Astrophysics Data System (ADS)

    Squires, Stephanie Michelle

    This study examined the lived experiences of African American women (AAW) who completed doctoral degrees in a STEM (science, technology, engineering, and mathematics) discipline in the United States. This study sought to fill the gap in the literature by examining how AAW described and made meaning of lived STEM educational experiences during doctoral degree completion in the context of the intersection of being African American and a woman. This study utilized a theoretical perspective based upon three theories: (a) critical race theory as a framework to gather AAW's narratives about STEM doctorate education, (b) Black feminist thought as a framework to view the intersection of being African American and a woman in the United States, and (c) the science identity model as a framework to view how women of color successfully complete scientific graduate degrees. Participants revealed that being an African American and a woman in a STEM doctoral program often complicated an already difficult process of completing the doctoral degree. The participants described the educational experience as challenging, particularly the writing of the dissertation. The challenges that the participants faced were due to various factors such as difficult advisor/advisee relationships, tedious writing and revision processes, politics, and lack of information regarding the doctoral degree process. The findings suggested that AAW participants confronted intrinsic bias while completing STEM doctoral degrees, which led to isolation and feelings of being an impostor---or feelings of not belonging in scientific studies. The findings also indicated that the women in this study ascribed success in dissertation writing and degree completion to one or more of the following attributes: (a) having a clear plan, (b) taking ownership of the writing process, (c) having an engaged advisor, (d) learning the writing style of the advisor, (e) understanding the temperament of the advisor, (f) personal will

    Background Major depressive disorder (MDD) is highly prevalent among HIV-infected (HIV+) individuals, and is associated with non-adherence to antiretroviral therapy (ART), and accelerated disease progression. MDD is underdiagnosed and undertreated among low-income African Americans, who are disproportionately impacted by the HIV epidemic. To improve detection and treatment of depression among African Americans living with HIV/AIDS, it is important to understand culturally and contextually relevant aspects of MDD and attitudes about mental health treatment. Methods A focus group session was conducted with seven providers and staff at a primary care center that serves a largely African-American community heavily impacted by the HIV epidemic in Washington, DC. Data were analyzed using an inductive approach to distill prominent themes, perspectives, and experiences among participating providers. Results Five themes emerged to characterize the lived experiences of HIV+ African-American patients: (a) Changes in perceptions of HIV over time; (b) HIV is comorbid with mental illness, particularly depression and substance abuse; (c) Stigma is associated with both HIV and depression; (d) Existing mental health services vary and are insufficient and (e) Suggestions for optimal treatment for comorbid HIV and depression. Limitation This study reflects the views of providers from one clinic in this community. Conclusion Substantial economic disadvantage, pervasive childhood adversity, limited education and limited resources jointly put members of this community at risk for acquisition of HIV and for development of depression and addictions. These contextual factors provide an important reminder that any patient-level depression identification or intervention in this community will have to be mindful of such circumstances. PMID:27347445

    2015-01-01

    Efficiency is defined as the use of resources in such a way as to maximize the production of goods and services. Improving efficiency has been the focus of management in many industries; however, it has not been until recently that incorporating efficiency models into healthcare has occurred. In particular, the study and development of improvement projects aimed at enhancing efficiency in GI have been growing rapidly in recent years. This focus on improving efficiency in GI has been spurred by the dramatic rise in the demand for endoscopic procedures as well as the rising number of insured patients requiring GI care coupled at the same time with limited resources in terms of staffing and space in endoscopy centers. This paper will critically review the history of efficiency in endoscopy centers, first by looking at other healthcare industries that have extensively studied and improved efficiency in their fields, examine a number of proposed efficiency metrics and benchmarks in endoscopy centers, and finally discuss opportunities where endoscopy centers could improve their efficiency.

    The NASA Lewis Research Center (LeRC), established in 1941, is one of ten NASA research centers in the country. It is situated on 350 acres of land in Cuyahoga County and occupies more than 140 buildings and over 500 specialized research and test facilities. Most of LeRC's facilities are located in the City of Cleveland; some are located within the boundaries of the cities of Fairview Park and Brookpark. LeRC is a lead center for NASA's research, technology, and development in the areas of aeropropulsion and selected space applications. It is a center of excellence for turbomachinery, microgravity fluid and combustion research, and commercial communication. The base research and technology disciplines which serve both aeronautics and space areas include materials and structures, instrumentation and controls, fluid physics, electronics, and computational fluid dynamics. This study investigates LeRC's economic impact on Northeast Ohio's economy. It was conducted by The Urban Center's Economic Development Program in Cleveland State University's Levin College of Urban Affairs. The study measures LeRC's direct impact on the local economy in terms of jobs, output, payroll, and taxes, as well as the indirect impact of these economic activities when they 'ripple' throughout the economy. To fully explain LeRC's overall impact on the region, its contributions in the areas of technology transfer and education are also examined. The study uses a highly credible and widely accepted research methodology. First, regional economic multipliers based on input-output models were used to estimate the effect of LERC spending on the Northeast Ohio economy. Second, the economic models were complemented by interviews with industrial, civic, and university leaders to qualitatively assess LeRC's impact in the areas of technology transfer and education.

  12. Text Messaging to Improve Hypertension Medication Adherence in African Americans: BPMED Intervention Development and Study Protocol

    2015-01-01

    Background Hypertension (HTN) is a major public health concern in the United States, with almost 78 million Americans age 20 years and over suffering from the condition. Moreover, HTN is a key risk factor for health disease and stroke. African Americans disproportionately shoulder the burdens of HTN, with greater prevalence, disease severity, earlier onset, and more HTN-related complications than age-matched whites. Medication adherence for the treatment of HTN is poor, with estimates indicating that only about half of hypertensive patients are adherent to prescribed medication regimens. Although no single intervention for improving medication adherence has emerged as superior to others, text message medication reminders have the potential to help improve medication adherence in African Americans with uncontrolled HTN as mobile phone adoption is very high in this population. Objective The purpose of this two-phased study was to develop (Phase I) and test in a randomized controlled trial (RCT) (Phase II) a text message system, BPMED, to improve the quality of medication management through increasing medication adherence in African Americans with uncontrolled HTN. Methods In Phase I, we recruited 16 target end-users from a primary care clinic, to assist in the development of BPMED through participating in one of three focus groups. Focus groups sought to gain patient perspectives on HTN, medication adherence, mobile phone use, and the use of text messaging to support medication adherence. Potential intervention designs were presented to participants, and feedback on the designs was solicited. In Phase II, we conducted two pilot RCTs to determine the feasibility, acceptability, and preliminary efficacy of BPMED in primary care and emergency department settings. Both pilot studies recruited approximately 60 participants, who were randomized equally between usual care and the BPMED intervention. Results Although data collection is now complete, data analysis from the

Many of the current and future projects are geared to Thomas Jefferson National Accelerator Facility (JLab) at Newport News, VA. JLab is the world's premier electron accelerator for nuclear physics, and GW is one of the charter members of the governing body of JLab, the Southeastern Universities Research Association (SURA). The George Washington Data Analysis Center (DAC) was created in 1998 by an agreement among the Department of Energy, Jefferson Lab, and the GW Center for Nuclear Studies.The activities of the DAC fall into four distinct categories: 1) Performing partial-wave analyses of fundamental two- and three-body reactions; 2) Maintenance of databases associated with these reactions; 3) Development of software to disseminate DAC results (as well as the results of competing model-independent analyses and potential approaches); and 4) Phenomenological and theoretical investigations which bridge the gap between theory and experiment; in particular, the extraction of N* and D * hadronic and electromagnetic couplings. Partial Wave Analyses (and the associated databases) available at GW are: Pion-Nucleon, Kaon-Nucleon, Nucleon-Nucleon, Pion Photoproduction, Pion Electroproduction, Kaon Photoproduction, Eta Photoproduction, Eta-Prime Photoproduction, Pion-Deuteron (elastic), and Pion-Deuteron to Proton+Proton.

  14. African American Advanced Placement chemistry students and their developing study habits: A phenomenologically-based interpretive study

    Rasmussen, Natalie D.

    The academic achievement gap between African American and White students has gained much attention in recent years. Much has been written about the causes of and reasons for this problem ranging from the vestigial effects of slavery to poor parenting. Much less has been written or understood about its solution. While it is impossible for educators to change the pasts of their African American students, it is possible to effect change for the few minutes in which they are in direct contact with them each day. If African American science students are taught effective study skills and habits, then perhaps they might have the tools to close the achievement gap themselves. The participants in this phenomenologically based interpretive study were five African American Advanced Placement Chemistry students from an inner-city high school. Three in-depth interviews were conducted with each of the participants during the beginning, middle and end of a semester. The purpose of the interviews was to locate the students in terms of their thought processes, experiences and perceived barriers concerning the nature and practice of effective study and retention of chemistry content. The interviews were recorded and transcribed. The texts were then analyzed for common themes. Five common themes emerged from the interviews. These were: (1) Homework vs. Study: a distinction between homework---which students knew how to approach; and study---which they did not. (2) Student Effort: their changing perception of adequate and effective study practices while in a rigorous course. (3) Teacher Rigor: they perceived high expectations and challenging work as a sign of respect from their teachers. (4) Parental Involvement: students' admission that they desired more input from parents regarding their academic performance. (5) Racial Considerations: their need to disprove negative stereotypes and their personal observations regarding racial differences in studying. A discussion of the themes and

    The risk of having a first stroke is nearly twice as high among African Americans compared to Caucasians. HIV/AIDS is an independent risk factor for stroke. Our study aimed to report the risk factors and short-term clinical outcomes of African Americans with HIV infection and new-onset stroke admitted at the Johns Hopkins Hospitals (2000-2012). Multivariate linear regression was used to examine the association between potential predictors and odds of an unfavorable outcome, defined as a higher modified Rankin Scale (mRS) score on hospital discharge. African Americans comprised 105/125 (84%) of HIV-infected new-onset stroke inpatients (median age 50 years; 69% men; median CD4 140/mL; ischemic 77%; 39% taking highly active antiretroviral therapy). Vascular risk factors were common: hypertension (67%), cigarette smoking (66%), dyslipidemia (42%), hepatitis C (48%), intravenous drug abuse (32%), and prior myocardial infarction (29%). Prior aspirin and statin use were uncommon (18%, 9%). Unfavorable outcome (mRS score 4-6, n = 22 of 90 available records) was noted in 24% of patients, including seven in-hospital deaths. On multivariate analyses, higher CD4 count on hospital admission was associated with a lower mRS (-0.2 mRS points per 1 unit increase in CD4, 95% CI (-0.3, 0), p = 0.03). Intracerebral hemorrhage was also associated with a lower mRS (1.0 points lower, 95% CI (0.2, 1.8) compared to ischemic stroke, p = 0.01) after adjustment for other potential predictors. This underscores the importance of HIV infection on functional stroke outcomes beyond its recognized influence on stroke risk. PMID:26155903

  16. A study of the influence of protective factors as a resource to African American males in traditional batterers' interventions.

    The purpose of this study was to examine the relationship between protective factors and the responses of African American males in traditional batterers' interventions. African American male batterers have been viewed as responding poorly to batterers' interventions and were reported in the literature as at risk for dropout and treatment failure. This research proposed that there were culturally related protective factors that enhanced traditional interventions for African American males, increasing their potential for changing abusive behaviors. This within-group study used secondary data to examine the influence of protective factors on the responses of 268 active duty Navy African American males. They were a sub-sample of 861 males randomly assigned to one of four different interventions for batterers. The interventions included a cognitive behavioral men's group, couple's group, safety and stabilization group, and a control group. Each of their cases had been officially substantiated by the Navy for assault of their spouses. The measures for the protective factors of religion, self-esteem, and family support were drawn from the original study's self-report measurement tool. The results of the statistical analyses were found to be significant. The protective factors performed as social controls for reducing certain types of abusive behaviors. Little research has been conducted on the influence of cultural factors on batterers intervention outcome for African Americans. This study established a strong support for further research.

    In this study, the influence of culture and discrimination on care-seeking behavior of elderly African Americans was explored. This was a qualitative phenomenological study that involved in-depth interviews with 15 African American men and women aged 60 and older in Alabama. The sample size of 15 was adequate for the phenomenological method of this study. While this was a small exploratory study and was not intended for any generalizations, it did provide a unique opportunity to hear the voices, the concerns, and the stories of elderly African Americans, which have often been overlooked in the literature. The following themes emerged from the analysis of data: (1) perception of health as ability to be active, (2) reluctance toward prescription medicine use, (3) lack of trust in doctors, (4) avoidance of bad news, (5) race of doctors, (6) use of home remedies, and (7) importance of God and spirituality on health, illness, and healing.

    Background The high burden of witnessing traumatic events has been demonstrated in previous research in South Africa. However, previous work has focused on PTSD rather than a broader range of psychopathological outcomes. This study examined the association between witnessing trauma and multiple outcomes including mood, anxiety, and substance use disorders. Methods Regression models measured the odds of mood, anxiety, and substance use disorders among those who reported witnessing in the South African Stress and Health Study. Discrete-time survival analysis was used to examine whether witnessing was associated with earlier onset of mental disorders. Results Witnessing trauma was more commonly reported among males and those with low-average education. Posttraumatic stress disorder, mood, and anxiety disorders varied significantly with witnessing status, and witnessing was associated with exposure to a higher number of traumatic events compared to other types of traumatic events. Respondents reporting witnessing trauma had elevated odds of mood and anxiety disorders, but not substance use disorders. Conclusion Witnessing trauma is common in the South African population and results in increased risk of mood and anxiety disorders. Interventions aimed at reducing the burden of trauma and its outcomes must now increase their focus on bystanders and other observers, rather than just focusing on those directly affected.

    INTRODUCTION: Ensuring adequate representation of all demographic groups in medical research is necessary in order to ensure that the benefits associated with participation are equitably shared. Mental health research is unique in that the stigma associated with mental illness, such as schizophrenia, further hinders participation. Using focus groups, we set out to explore the attitudes and views of African Americans with regard to schizophrenia and medical research. METHODS: Four focus group discussions were conducted, with 23 participants divided into two groups of working and retired adults, and two groups of full- and part-time students selected from inner-city residents of Birmingham, AL, and surrounding counties. Data obtained were analyzed using the content analysis method. RESULTS: Diverse views were expressed about the cause of mental illness, and much of this was influenced by cultural beliefs. There was considerable misunderstanding of schizophrenia, and the majority of participants described the disease in terms of positive symptoms only. Whereas for older participants the Tuskegee syphilis study experience was an important factor in their reluctance to participate in medical research, younger participants expressed no knowledge of the study. Among younger participants an assumed level of social distrust was evident, with prominent fear of participating in research that employs physically intrusive methods. CONCLUSION: The provision of accurate information through trusted community sources and open dialogue will help to dispel myths, correct faulty assumptions and increase African-American participation in schizophrenia research.

    Walls, Leon

    Nature of Science is one of the most fundamental aspects of understanding science. How different cultures, races and ethnicities see and interpret science differently is critical. However, the NOS views specific to African American teachers and learners have gone largely unresearched. The views of a purposeful sample of African American third grade children reported in this study contribute to efforts to make science equitable for all students. Conducted in two Midwest urban settings, within the students' regular classrooms, three instruments were employed: Views of Nature of Science Elementary (an interview protocol), Elementary Draw a Scientist Test (a drawing activity supplemented by an explicating narrative), and Identify a Scientist (a simple select-a-photo technique supported by Likert-measured sureness). The responses provided by twenty-three students were coded using qualitative content analysis. The findings are represented in three main categories: Science - is governed by experimentation, invention and discovery teach us about the natural world, school is not the only setting for learning science; Scientists - intelligent, happy, studious men and women playing multiple roles, with distinct physical traits working in laboratories; Students - capable users and producers of science and who view science as fun. This study advocates for: use of such instruments for constant monitoring of student views, using the knowledge of these views to construct inquiry based science lessons, and increased research about students of color.

    The purposes of this study were to determine what program characteristics African American parents consider when they enroll their children into an informal science education enrichment program, the parents' evaluation of a program called Jordan Academy in which they enrolled their children, and the alignment of the parents' perspectives with Black Cultural Ethos (BCE). BCE refers to nine dimensions posited by Wade Boykin, a psychologist, as comprising African American culture. Participants were parents of students that attended Jordan Academy, an informal science enrichment program designed for third through sixth grade students from underserved populations. Qualitative methodologies were utilized to perform a thorough assessment of parents' perspectives. Data sources included classroom observations, student surveys, academy curriculum, photos and video-taped class sessions. Data included teachers and parents' responses to semi-structured, audio recorded interviews and students' written responses to open-ended items on the program's evaluation instrument. The data were analyzed for themes and the findings compared to Black Cultural Ethos. Findings revealed that the participants believed that informal science education offered their children opportunities not realized in the formal school setting - a means of impacting their children holistically. The parents expressed the academic, cultural, and personal development of their children in their characterizations of the ideal informal science education experience and in their evaluations of Jordan Academy. Overall, the parents' views emphasized the BCE values of harmony, affect, verve, movement, orality and communalism. The study has important implications for practices within and research on informal science education.

    To determine the incidence rate of cardiovascular disease (CVD) and its association with conventional and less well-established risk factors in African Americans with diabetes, we studied 741 African Americans aged 45 to 64 years with diabetes, in the Atherosclerosis Risk in Communities (ARIC) study. Risk factors were measured from 1987 to 1989, and incident CVD (n = 143 coronary heart disease (CHD) or stroke events) was ascertained through 1998. The crude incidence rate (per 1000 person-years) of CVD was 22.5 (11.9 for CHD and 12.0 for stroke). After multivariate adjustments, total cholesterol, prevalent hypertension and current smoking were significantly and positively associated with incident CVD among these African Americans with diabetes. Among the non-conventional risk factors, serum creatinine, factor VIII, von Willebrand factor, and white blood cell count were positively and serum albumin negatively and independently associated with CVD incidence. Adjusted relative risks for highest versus lowest tertiles of these risk factors ranged from 1.77 to 2.13. This study confirms that the major risk factors (hypercholesterolemia, hypertension and smoking) are important determinants of CVD in African Americans with diabetes. In addition, several blood markers of hemostasis or inflammatory response and elevated serum creatinine also proved to be CVD risk factors in African Americans with diabetes. PMID:12510702

    Aerodynamic, heat transfer, and system design studies to determine removable modifications for the Space Shuttle orbiter that would extend its forward center-of-gravity triom capability are summarized. Wind-tunnel tests were conducted at Mach numbers ranging from 0.25 to 20.3 to determine the most effective aerodynamic modifications. Heat transfer and system design studies determined the impact of the modifications on the thermal protection system and structural weight of the vehicle. The most effective modifications were in-fillet canards or a forward extension of the existing forward wing fillet.

    The transmission of HIV/AIDS among African American women through heterosexual sex is an epidemic. Critical themes extracted from the HIV/AIDS sexual assertiveness literature revealed that: (a) sexual assertiveness is related to HIV risk, (b) sexual assertiveness is related to communication, and (c) women with low sexual assertiveness are at risk for HIV. This descriptive study sought to answer the following research question: What do young adult college attending African American women self-report about asking information about their partner's sexual history? The multifaceted model of HIV risk is the theoretical framework which guided this descriptive study. A basic tenet of the multifaceted model of HIV risk is that there is no single predictor of women's HIV risk behavior. Results revealed that 104 young adult college attending African American women who volunteered to attend a one day HIV prevention training overall scored high on a Sexual Assertive Scale on subscales of Information Communication, Refusal, and Pregnancy/STD Prevention Subscale, and scored in the medium range on the Initiation Subscales. The Information Communication and Pregnancy/ STD Prevention Subscale received the highest scores. More research is needed targeting diverse African American females with different socioeconomic status, various locations, and educated to determine their sexual assertiveness with partners which are essential in developing specific programs for diverse groups of African American females.

    A representative sample of 365 low-income African-American preschool children aged 3-5 years was studied to determine the association between sugar-sweetened beverage consumption (soda, fruit drinks, and both combined) and overweight and obesity. Children were examined at a dental clinic in 2002-2003 and again after 2 years. Dietary information was collected using the Block Kids Food Frequency Questionnaire. A BMI score was computed from recorded height and weight. Overweight and obesity were defined by national reference age-sex specific BMI: those with an age-sex specific BMI>or=85th, but <95th percentile as overweight and those with BMI>or=95th age-sex specific percentile as obese. The prevalence of overweight was 12.9% in baseline, and increased to 18.7% after 2 years. The prevalence of obesity increased from 10.3 to 20.4% during the same period. Baseline intake of soda and all sugar-sweetened beverages were positively associated with baseline BMI z-scores. After adjusting for covariates, additional intake of fruit drinks and all sugar-sweetened beverages at baseline showed significantly higher odds of incidence of overweight over 2 years. Among a longitudinal cohort of African-American preschool children, high consumption of sugar-sweetened beverages was significantly associated with an increased risk for obesity.

    The South African lion (Panthera leo) population is highly fragmented. One-third of its wild lions occur in small (<1000 km(2)) reserves. These lions were reintroduced from other areas of the species' historical range. Management practices on these reserves have not prioritized genetic provenance or heterozygosity. These trends potentially constrain the conservation value of these lions. To ensure the best management and long-term survival of these subpopulations as a viable collective population, the provenance and current genetic diversity must be described. Concurrently, poaching of lions to supply a growing market for lion bones in Asia may become a serious conservation challenge in the future. Having a standardized, validated method for matching confiscated lion parts with carcasses will be a key tool in investigating these crimes. We evaluated 28 microsatellites in the African lion using samples from 18 small reserves and 1 captive facility in South Africa, two conservancies in Zimbabwe, and Kruger National and Kgalagadi Transfrontier Parks to determine the loci most suited for population management and forensic genetic applications. Twelve microsatellite loci with a match probability of 1.1×10(-5) between siblings were identified for forensics. A further 10 could be added for population genetics studies.

    Objective Detection of meningococcal carriers is key to understanding the epidemiology of Neisseria meningitidis, yet no gold standard has been established. Here, we directly compare two methods for collecting pharyngeal swabs to identify meningococcal carriers. Methods We conducted cross-sectional surveys of schoolchildren at multiple sites in Africa to compare swabbing the posterior pharynx behind the uvula (U) to swabbing the posterior pharynx behind the uvula plus one tonsil (T). Swabs were cultured immediately and analyzed using molecular methods. Results One thousand and six paired swab samples collected from schoolchildren in four countries were analyzed. Prevalence of meningococcal carriage was 6.9% (95% CI: 5.4-8.6%) based on the results from both swabs, but the observed prevalence was lower based on one swab type alone. Prevalence based on the T swab or the U swab alone was similar (5.2% (95% CI: 3.8-6.7%) versus 4.9% (95% CI: 3.6-6.4%) respectively (p=0.6)). The concordance between the two methods was 96.3% and the kappa was 0.61 (95% CI: 0.50-0.73), indicating good agreement. Conclusions These two commonly used methods for collecting pharyngeal swabs provide consistent estimates of the prevalence of carriage, but both methods misclassified carriers to some degree, leading to underestimates of the prevalence.

    Newly immigrated persons, whatever their origin, tend to fall in the lower socioeconomic levels. In fact, failure of an asylum application renders one destitute in a large proportion of cases, often resulting in a profound lack of access to basic necessities. With over a third of HIV positive failed asylum seekers reporting no income, and the remainder reporting highly limited resources, poverty is a reality for the vast majority. The purpose of the study was to determine the basic social processes that guide HIV positive undocumented migrant's efforts to gain health services in the UK. The study used the Grounded Theory Approach. Theoretical saturation occurred after 16 participants were included in the study. The data included reflections of the prominent factors related to the establishment of a safe and productive life and the ability of individuals to remain within the UK. The data reflected heavily upon the ability of migrants to enter the medical care system during their asylum period, and on an emerging pattern of service denial after loss on immigration appeal. The findings of this study are notable in that they have demonstrated sequence of events along a timeline related to the interaction between the asylum process and access to health-related services. The results reflect that African migrants maintain a degree of formal access to health services during the period that they possess legal access to services and informal access after the failure of their asylum claim. The purpose of this paper is to examine the basic social processes that characterize efforts to gain access to health services among HIV positive undocumented African migrants to the UK. The most recent estimates indicate that there are a total of 618,000 migrants who lack legal status within the UK. Other studies have placed the number of undocumented migrants within the UK in the range of 525,000-950,000. More than 442,000 are thought to dwell in the London metropolitan area. Even in

    2013-01-01

    Numerous single nucleotide polymorphisms (SNPs) associated with breast cancer susceptibility have been identified by genome-wide association studies (GWAS). However, these SNPs were primarily discovered and validated in women of European and Asian ancestry. Because linkage disequilibrium is ancestry-dependent and heterogeneous among racial/ethnic populations, we evaluated common genetic variants at 22 GWAS-identified breast cancer susceptibility loci in a pooled sample of 1502 breast cancer cases and 1378 controls of African ancestry. None of the 22 GWAS index SNPs could be validated, challenging the direct generalizability of breast cancer risk variants identified in Caucasians or Asians to other populations. Novel breast cancer risk variants for women of African ancestry were identified in regions including 5p12 (odds ratio [OR] = 1.40, 95% confidence interval [CI] = 1.11–1.76; P = 0.004), 5q11.2 (OR = 1.22, 95% CI = 1.09–1.36; P = 0.00053) and 10p15.1 (OR = 1.22, 95% CI = 1.08–1.38; P = 0.0015). We also found positive association signals in three regions (6q25.1, 10q26.13 and 16q12.1–q12.2) previously confirmed by fine mapping in women of African ancestry. In addition, polygenic model indicated that eight best markers in this study, compared with 22 GWAS-identified SNPs, could better predict breast cancer risk in women of African ancestry (per-allele OR = 1.21, 95% CI = 1.16–1.27; P = 9.7 × 10–16). Our results demonstrate that fine mapping is a powerful approach to better characterize the breast cancer risk alleles in diverse populations. Future studies and new GWAS in women of African ancestry hold promise to discover additional variants for breast cancer susceptibility with clinical implications throughout the African diaspora.

    Open angle glaucoma (OAG) is a severe ocular disease characterized by progressive and irreversible vision loss. While elevated intraocular pressure (IOP) is a well-established risk factor for OAG, the progression of OAG in many cases, despite IOP treatment, suggests that other risk factors must play significant roles in the development of the disease. For example, various structural properties of the eye, ocular blood flow properties, and systemic conditions have been identified as risk factors for OAG. Ethnicity has also been indicated as a relevant factor that affects the incidence and prevalence of OAG; in fact, OAG is the leading cause of blindness among people of African descent. Numerous clinical studies have been designed to examine the possible correlation and causation between OAG and these factors; however, these studies are met with the challenge of isolating the individual role of multiple interconnected factors. Over the last decade, various mathematical modeling approaches have been implemented in combination with clinical studies in order to provide a mechanical and hemodynamical description of the eye in relation to the entire human body and to assess the contribution of single risk factors to the development of OAG. This review provides a summary of the clinical evidence of ocular structural differences, ocular vascular differences and systemic vascular differences among people of African and European descent, describes the mathematical approaches that have been proposed to study ocular mechanics and hemodynamics while discussing how they could be used to investigate the relevance to OAG of racial disparities, and outlines possible new directions of research.

    Breast cancer survival rates are lower in African Americans (AAs) than in Caucasians, owing in part to a higher prevalence of obesity in the former, which increases the risk of recurrence and mortality. The Women's Intervention Nutrition Study (WINS) found that Caucasian women who followed a low-fat eating plan experienced a lower rate of cancer recurrence than women who maintained their usual diets. The purpose of this study was to test the feasibility of a WINS plan tailored to the cultural needs of AA breast cancer survivors. This feasibility pilot study was conducted at a university National Cancer Institute-designated comprehensive cancer center outpatient clinic with AA breast cancer survivors. The culturally specific WINS (WINS-c) plan included eight individual counseling sessions, five educational group meetings, and follow-up telephone calls over a 1-year period. Outcome measures included dietary fat, triglyceride, insulin and glucose levels, and fruit and vegetable intake. Participants (n = 8) had a mean age of 61.1 years (standard error of the mean (SEM) 3.1 years) and a mean BMI of 32 kg/m(2) (SEM 4.25 kg/m)(2). Baseline daily fat consumption decreased from 64.6 g (range 36.8-119.6g) to 44.0 g (21.6-73.4g) at 52 weeks (p = 0.07). Mean daily consumption of fruits and vegetables increased by 36% and 15%, respectively. Mean triglyceride levels decreased at 12 months (p < 0.05). Sustained hyperinsulinemia was noted in most participants, including those without diabetes. Mean calcium and vitamin D consumption decreased over the 1-year study period. In AA breast cancer survivors, the WINS-c program resulted in a trend toward reduced fat consumption and may represent a sustainable approach in this population for improvement of diet quality after breast cancer.

    Implementation of assisted breeding in the captive African wild dog is restricted by a current lack of knowledge on their reproductive physiology and the apparent difficulty of effectively manipulating the complex social dynamic of the pack in order to conduct reproductive procedures. In this study, we describe protocols for the safe and repeated capture and restraint of the African wild dog (n=7) as well as techniques for assessment of male reproductive function, semen collection and preservation. In a serendipitous finding, captive African wild dogs appeared to display significant seasonal change in male reproduction. Testicular volume and tone, spermatorrhea and the ability to collect semen by electroejaculation all increased significantly during late summer and then subsequently declined by early spring. While there were no detectable seasonal changes in testosterone concentration in the population as whole, the alpha-dominant male in both years of the study, had a highly elevated testosterone concentration compared to subordinate males. Semen collection by electroejaculation during the late summer was most effective in peri-pubertal males (15 months) when all seven electroejaculates were of adequate quality for cryopreservation. In the second breeding season (27 months), there were numerous changes in the pack hierarchy and electroejaculation was not as successful (3/7). The characteristics of electroejaculated semen collected in the breeding season are described for seven animals including the first descriptions and incidence of sperm abnormalities in the species. Semen (n=7) was frozen using a Tris-citrate fructose buffer and final egg yolk and glycerol concentration of 20% and 4%, respectively. Sperm were loaded into 0.25 mL straws, frozen in liquid nitrogen vapor and then thawed at 37 degrees C. Initial post-thaw survival of spermatozoa was encouraging (% motile: 31.8+/-5.8%; rate: 2.8+/-0.3; % intact plasma membranes: 33.4+/-5.3% and the % of damaged

    The barbershop is a promising setting where African-American men might receive information and education about prostate cancer. In this study, we assessed the feasibility of engaging rural barbershops as venues for barbers to deliver a prostate cancer education intervention to increase informed decision-making for prostate cancer screening among customers. Twelve barbershops were recruited from two separate micropolitan areas in Georgia as intervention and control sites. Structured interviews were conducted with 11 barbers in both sites about customer characteristics as well as their willingness to participate in the study. The interviews were audio recorded and transcribed for analysis. In the intervention site, six barbers completed a survey and a pre-/posttest prostate cancer knowledge instrument following training classes. Barbers reported a wide average range of customers served per week (50 to 300). African-American men made up an average of 87% of customers. Barbers thought prostate cancer was an important discussion topic, felt they would be comfortable discussing it, and supported the participation of their barbershop in the study. For intervention group barbers, there was a statistically significant difference between the average pretest knowledge score of 72% (mean 12.2, SD=3.2) and the posttest knowledge score of 89% (mean 15.2, SD=1.1) (P=0.03) on the 17-item prostate cancer knowledge instrument. Based on the multiple interactions with the barbers, there was high receptivity to the topic and consensus about the importance of addressing prostate cancer with their customers. Rural barbershops represent feasible venues for delivering a prostate cancer education intervention. PMID:25288347

    Background Chronic kidney disease (CKD) remains a prevalent public health problem that disproportionately affects African Americans, despite intense efforts targeting traditional risk factors. Periodontal disease, a chronic bacterial infection of the oral cavity, is both common and modifiable and has been implicated as a novel potential CKD risk factor. We sought to examine to what extent periodontal disease is associated with kidney function decline. Methods Retrospective cohort study of 699 African American participants with preserved kidney function defined by an estimated glomerular filtration rate (eGFR) >60ml/min/1.73m2 at baseline who underwent complete dental examinations as part of the Dental-Atherosclerosis Risk in Communities study (1996–1998) and subsequently enrolled in the Jackson Heart Study (2000–2004). Using multivariable Poisson regression we examined the association of periodontal disease (severe vs. non-severe) with incident CKD defined as incident eGFR<60ml/min/1.73m2 and rapid (5% annualized) eGFR decline at follow-up among those with preserved eGFR at baseline. Results Mean age at baseline was 65.4 years (SD 5.2) and 16.3% (n=114) had severe periodontal disease. There were 21 cases (3.0%) of incident CKD after a mean follow-up of 4.8 (SD 0.6) years. Compared to participants with non-severe periodontal disease, those with severe periodontal disease had a 4-fold greater rate of incident CKD [adjusted incidence rate ratio 4.18, 95% CI (1.68 – 10.39), p=0.002]. Conclusion Severe periodontal disease is prevalent among a population at high-risk for CKD and is associated with clinically significant kidney function decline. Further research is needed to determine if periodontal disease treatment alters the trajectory of renal deterioration. PMID:26110451

    Background Persistent racial disparities in breastfeeding show that African American women breastfeed at the lowest rates. Return to work is a critical breastfeeding barrier for African American women who return to work sooner than other ethnic groups and more often encounter unsupportive work environments. They also face psychosocial burdens that make breastfeeding at work uniquely challenging. Participants share personal struggles with combining paid employment and breastfeeding and suggest workplace and personal support strategies that they believe will help continue breastfeeding after a return to work. Objective To explore current perspectives on ways to support African American mothers' workplace breastfeeding behavior. Methods Pregnant African American women (n = 8), African American mothers of infants (n = 21), and lactation support providers (n = 9) participated in 1 of 6 focus groups in the Greater Detroit area. Each focus group audiotape was transcribed verbatim. Thematic analysis was used to inductively analyze focus group transcripts and field notes. Focus groups explored thoughts, perceptions, and behavior on interventions to support African American women's breastfeeding. Results Participants indicate that they generally believed breastfeeding was a healthy option for the baby; however, paid employment is a critical barrier to successful breastfeeding for which mothers receive little help. Participants felt breastfeeding interventions that support working African American mothers should include education and training for health care professionals, regulation and enforcement of workplace breastfeeding support policies, and support from peers who act as breastfeeding role models. Conclusion Culturally appropriate interventions are needed to support breastfeeding among working African American women. PMID:25714345

    This paper introduces a multi-regional electricity trade study for the Southern African Power Pool (SAPP). A unique mathematical model was developed for the hydrothermal scheduling/commitment and dispatch of the diverse systems of the region. All of the international interconnections were considered in the formulation, as were the major transmission lines inside the regions. The model quantified new trade arrangements that could minimize the operating cost of the region. The model was fully discussed in a SAPP/Purdue workshop, held at Purdue University, August 19 to September 3, 1997. All parameters and data were verified by the delegates from the SAPP. Preliminary results show that much higher trade quantities can be realized compared with the existing long term contracts. The results from the new policy showed a typical day cost reduction of about 6.2% to 8%, compared with the operating cost of the existing long-term contracts.

    Family socialization, which includes parental control and support, plays an important role in reducing the likelihood of adolescent involvement in conflict. This study examined the strategies that urban parents living in neighborhoods with high crime rates suggest to help their adolescent children avoid or deescalate conflict. Data come from 48 African American parent/adolescent dyads recruited through the youths’ middle school. Dyads responded to three video-taped scenarios depicting youth in potential conflict situations. Qualitative methods were used to identify 11 strategies parents suggested to help youth avoid or deescalate conflict. Although the majority of parents advocated for non-violent solutions, these same parents described situations in which their child may need to use violence. These findings have important implications for family-focused violence prevention programs. PMID:26726283

    2002-01-01

    Recruitment of African Americans as research participants continues as a major challenge for researchers studying health and human behavior. Numerous reasons for low participation by African Americans have been cited, most of which evolve around four primary factors: social injustice, education, economics, and cultural differences. To ensure adequate representation of the diversity within the U.S. population in research, the federal government mandates the inclusion of individuals from underrepresented groups as study participants. For African Americans, this number is approximately 12%. Controversy exists, however, as to whether published research studies reflect adequate representation of African Americans as study participants. This article reports a successful approach to the recruitment and retention of 80 African American adults who participated in a study investigating language comprehension in aging. PMID:12491954

    The AfricaArray programme was launched in 2005 to conduct research that promotes development in Africa by building human and infrastructural capacity in support of the mineral exploration, mining, geohazard and environmental sectors. The AfricaArray "backbone" network now consists of 51 geophysical observatories in 20 sub-Saharan countries. Most stations are equipped with broadband seismometers, while 25 stations have continuous GPS sensors and 22 stations have meteorological packs. In addition, several temporary seismic arrays have been deployed to investigate the seismotectonics of the East African Rift System, the extent of the Congo craton, and the rifting of Mozambique and Madagascar. In this paper we will present results pertinent to large-scale crustal and mantle geodynamic processes that have been obtained by AfricaArray researchers. Brandt and Mulibo elucidated the relationship between the African Superplume, Superswell and the East African Rift System by studying the seismic velocity structure of the mantle. Kgaswane jointly inverted P-wave receiver functions (PRFs) and surface waves, and found that the Kalahari Craton lower crust is largely mafic, except for a few terrains such as the Kimberley. Kgaswane also produced evidence that supports a link between the eastern and western lobes of the Bushveld Complex. Mangongolo used surface wave tomography to define the south-western boundary of the Congo Craton. El Tahir used PRFs to investigate the crustal structure of the Khartoum Basin, while Tugume determined the Moho depths and Poisson's ratios of the Precambrian crust in East Africa. Manzi reprocessed 3D reflection seismic data covering part of the Witwatersrand goldfields using seismic attribute analysis methods, and has provided new constraints on the evolution of the Basin during the Neoarchean. Loots interpreted a 105 km 2D seismic reflection profile immediately to the north of the Cape Fold Belt, imaging the Karoo and Cape Supergroup rocks and the

    Insulin resistance (IR) is a key determinant of type 2 diabetes (T2D) and other metabolic disorders. This genome-wide association study (GWAS) was designed to shed light on the genetic basis of fasting insulin (FI) and IR in 927 non-diabetic African Americans. 5 396 838 single-nucleotide polymorphisms (SNPs) were tested for associations with FI or IR with adjustments for age, sex, body mass index, hypertension status and first two principal components. Genotyped SNPs (n = 12) with P < 5 × 10(-6) in African Americans were carried forward for de novo genotyping in 570 non-diabetic West Africans. We replicated SNPs in or near SC4MOL and TCERG1L in West Africans. The meta-analysis of 1497 African Americans and West Africans yielded genome-wide significant associations for SNPs in the SC4MOL gene: rs17046216 (P = 1.7 × 10(-8) and 2.9 × 10(-8) for FI and IR, respectively); and near the TCERG1L gene with rs7077836 as the top scoring (P = 7.5 × 10(-9) and 4.9 × 10(-10) for FI and IR, respectively). In silico replication in the MAGIC study (n = 37 037) showed weak but significant association (adjusted P-value of 0.0097) for rs34602777 in the MYO5A gene. In addition, we replicated previous GWAS findings for IR and FI in Europeans for GCKR, and for variants in four T2D loci (FTO, IRS1, KLF14 and PPARG) which exert their action via IR. In summary, variants in/near SC4MOL, and TCERG1L were associated with FI and IR in this cohort of African Americans and were replicated in West Africans. SC4MOL is under-expressed in an animal model of T2D and plays a key role in lipid biosynthesis, with implications for the regulation of energy metabolism, obesity and dyslipidemia. TCERG1L is associated with plasma adiponectin, a key modulator of obesity, inflammation, IR and diabetes. PMID:22791750

  2. Genomic African and Native American Ancestry and Chagas Disease: The Bambui (Brazil) Epigen Cohort Study of Aging

    PubMed Central

    2016-01-01

    Background The influence of genetic ancestry on Trypanosoma cruzi infection and Chagas disease outcomes is unknown. Methodology/Principal Findings We used 370,539 Single Nucleotide Polymorphisms (SNPs) to examine the association between individual proportions of African, European and Native American genomic ancestry with T. cruzi infection and related outcomes in 1,341 participants (aged ≥ 60 years) of the Bambui (Brazil) population-based cohort study of aging. Potential confounding variables included sociodemographic characteristics and an array of health measures. The prevalence of T. cruzi infection was 37.5% and 56.3% of those infected had a major ECG abnormality. Baseline T. cruzi infection was correlated with higher levels of African and Native American ancestry, which in turn were strongly associated with poor socioeconomic circumstances. Cardiomyopathy in infected persons was not significantly associated with African or Native American ancestry levels. Infected persons with a major ECG abnormality were at increased risk of 15-year mortality relative to their counterparts with no such abnormalities (adjusted hazard ratio = 1.80; 95% 1.41, 2.32). African and Native American ancestry levels had no significant effect modifying this association. Conclusions/Significance Our findings indicate that African and Native American ancestry have no influence on the presence of major ECG abnormalities and had no influence on the ability of an ECG abnormality to predict mortality in older people infected with T. cruzi. In contrast, our results revealed a strong and independent association between prevalent T. cruzi infection and higher levels of African and Native American ancestry. Whether this association is a consequence of genetic background or differential exposure to infection remains to be determined. PMID:27182885

    There is increasing evidence of an association between stress related to job strain and hypertension. However little data exist on stress from racism and race-based discrimination at work (RBDW). The objective of this study was to investigate whether blood pressure (BP) outcomes are positively associated with stressful racism towards African-Americans from non-African-Americans as well as RBDW from other African-Americans. The metro Atlanta heart disease study was a population-based study which included 356 African-American men and women, aged >/=21 years, residing in metropolitan Atlanta, Georgia during 1999-2001. Perceived stress was self-reported by 197 participants for racism from non-African-Americans and 95 for RBDW from other African-Americans. Sitting systolic (SBP) and diastolic (DBP) BP were taken at a clinic visit and was the average of the last two of three BP measures. Hypertension was self-reported as physician-diagnosed high BP on 2 or more visits. Logistic and least-squares linear regression models were fit accordingly and separately for each type of stress, adjusting for age, gender, body mass index, and coping abilities. The likelihood of hypertension significantly increased with higher levels of perceived stress following racism from non-African-Americans, but not from RBDW from other African-Americans; adjusted odd ratios (95% CI) were 1.4 (1.0, 1.9) and 1.2 (0.8, 1.5) per unit increment of stress. The adjusted magnitude of SBP and DBP increase between low and very high level of stress, conversely, was greater when RBDW originated from African-Americans than racism from non-African-Americans. Stressful racism and RBDW encounters are associated with increased SBP and DBP and increased likelihood of hypertension in African-Americans. Future studies with a larger sample size are warranted to further explore these findings for mechanistic understanding and occupational policy consideration regarding stress risk reduction.

    Demands in computational power, particularly in the area of computational fluid dynamics (CFD), led NASA Ames Research Center to study advanced computer architectures. One architecture being studied is the static data flow architecture based on research done by Jack B. Dennis at MIT. To improve understanding of this architecture, a static data flow simulator, written in Pascal, has been implemented for use on a Cray X-MP/48. A matrix multiply and a two-dimensional fast Fourier transform (FFT), two algorithms used in CFD work at Ames, have been run on the simulator. Execution times can vary by a factor of more than 2 depending on the partitioning method used to assign instructions to processing elements. Service time for matching tokens has proved to be a major bottleneck. Loop control and array address calculation overhead can double the execution time. The best sustained MFLOPS rates were less than 50% of the maximum capability of the machine.

    2015-02-01

    Community bioethics dialogues were held on the topic of patient-centered outcomes research (PCOR) and comparative effectiveness research (CER). Participants were 65 and older and represented either a lower income, African American group (A) or a higher income White group (B). Participants were presented with a variety of background reading and study materials. Meetings were held 2 hr per week for 6 weeks. The groups showed both independence in judgment from the investigators and diversity of opinion between the two groups. Group B addressed more topics than Group A and in some instances explored additional policy nuances. Members of Group A appeared more cognizant of issues of social justice that affect vulnerable populations and appeared leery of approaches that suggested possible disrespect for their own personal experiences. Future plans call for both repeating the dialogue with additional, diverse community groups and repeating community bioethics dialogues on new topics with the same groups.

    This study reports on the association between religious beliefs and behaviors and the change in both general and religious social support using two waves of data from a national sample of African Americans. The Religion and Health in African Americans (RHIAA) study is a longitudinal telephone survey designed to examine relationships between various aspects of religious involvement and psychosocial factors over time. RHIAA participants were 3173 African American men (1281) and women (1892). A total of 1251 men (456) and women (795) participated in wave 2 of data collection. Baseline religious behaviors were associated with increased overall religious social support from baseline to wave 2 (p < .001) and with increased religious social support from baseline to wave 2 in each of the following religious social support subscales: emotional support received (p < .001), emotional support provided (p < .001), negative interaction (p < .001), and anticipated support (p < .001). Religious beliefs did not predict change in any type of support, and neither beliefs nor behaviors predicted change in general social support. African Americans who are active in faith communities showed increases in all types of religious social support, even the negative aspects, over a relatively modest longitudinal study period. This illustrates the strength of the church as a social network and the role that it plays in people's lives.

    The quality of dating relationships in adolescence can have long lasting effects on identity development, self-esteem, and interpersonal skills, and can shape values and behaviors related to future intimate relationships. The aims of this study were to: 1) investigate how African American adolescent girls characterize healthy relationships; and 2) describe the meanings of these characteristics in the context of the Centers for Disease Control and Prevention’s (CDC) 12 healthy dating relationship qualities. We conducted semi-structured one-on-one in-depth interviews with 33 African American high school girls in the mid-Atlantic region. Trained staff transcribed interviews verbatim and entered the data into ATLAS.ti for coding and analysis. Participants’ specified and vividly described eight healthy relationship characteristics: good communication, honesty, trust, respect, compromise, understanding, individuality, and self-confidence. Of these characteristics, three (good communication, compromise, and respect) were described in ways discordant with CDC’s definitions. Findings highlight a need to better understand how girls develop values and ascribe characteristics of healthy relationships in order to reduce their risk for teen dating violence. PMID:25168629

    Africa is the source of all modern humans, but characterization of genetic variation and of relationships among populations across the continent has been enigmatic. We studied 121 African populations, four African American populations, and 60 non-African populations for patterns of variation at 1327 nuclear microsatellite and insertion/deletion markers. We identified 14 ancestral population clusters in Africa that correlate with self-described ethnicity and shared cultural and/or linguistic properties. We observed high levels of mixed ancestry in most populations, reflecting historical migration events across the continent. Our data also provide evidence for shared ancestry among geographically diverse hunter-gatherer populations (Khoesan speakers and Pygmies). The ancestry of African Americans is predominantly from Niger-Kordofanian (~71%), European (~13%), and other African (~8%) populations, although admixture levels varied considerably among individuals. This study helps tease apart the complex evolutionary history of Africans and African Americans, aiding both anthropological and genetic epidemiologic studies. PMID:19407144

    In order to adequately perform its many diverse tasks as a scholars' society and as the German National Academy of Sciences, the Deutsche Akademie der Naturforscher Leopoldina needs to view itself in a historical context. This can only happen as part of a culture of remembrance which fosters the memory of the Leopoldina's past and subjects this to a critical analysis in the context of the history of science and academies. The newly founded Leopoldina Study Center for the History of Science and Science Academies is to be a forum that pursues established forms of historical research at the Leopoldina, organizes new scientific projects, and presents its findings to the public. The aim is to involve as many Leopoldina members as possible from all of its disciplines, as well as to collaborate with national and international partners.

    Background There is little research regarding whether working as a physician affects cancer risk. Moreover, there is no research on cancer prevalence among physicians in Korea. This study utilized the Korea National Cancer Incidence Database to determine whether the prevalence of cancer among physicians differs from the prevalence of cancer within the general population. Methods We analyzed the medical records of a representative sample of 382 doctors who underwent a health examination between 2010 and 2013 at a health examination center in a Ewha Womans University Medical Center.Cancer incidence was measured as cases that were eventually diagnosed as cancer according to a biopsy. Results We collected medical records from 382 physicians (mean age, 51.9±8.1 years) and calculated the standardized prevalence ratios compared to the general population. Thirty physicians (9 male and 21 female) were identified as having cancer. Physicians had a significantly higher prevalence of cancer compared to the general population.Cancer prevalence in male physicians was found to be 2.47 times higher than the prevalence expected within the general population (P=0.006). Among female physicians, cancer prevalence was 3.94 times higher than that in the general population (P<0.001). Conclusion This study revealed that physicians had a higher prevalence of cancer compared to the general population in Korea, which suggests that there may be a problem present in the health care of physicians. Changes to the working environment of physicians will be needed to reduce the high prevalence of cancer among physicians. PMID:27073607

    African American adolescent males who have sex with males (MSMs) have a high prevalence of sexually transmitted diseases (STDs) that has been directly linked to lack of access to primary care providers and reluctance to disclose their sexuality. The human papillomavirus (HPV) is the most common STD with more than 40 different serotypes and can lead to anal/genital warts as well as oral and genital cancers. The HPV vaccine if taken prior to an adolescent becoming sexually active serves a prophylactic function. The HPV vaccine is approved by the Food and Drug Administration (FDA) for girls and boys; however, HPV vaccination rates among adolescents within different minority and underserved communities have been disappointing even though these groups are disproportionately infected with the HPV virus and certain male-specific cancers. Little is known about the uptake of the vaccine among African American MSMs and thus the aim of this study. This qualitative study is based on the health belief model and assessed participants' level of awareness of HPV, the HPV vaccine, and HPV-related illnesses among 24 African American male adolescents between 16 and 18 years old who self identify as MSMs. As part of a larger study, two focus groups were conducted for African American MSMs. Participants failed to understand their potential risk for HPV given the higher rates of STD infection experienced by MSMs. They expressed very little knowledge of the HPV vaccine and are also not aware of the complications of HPV virus infection. However, they were very eager to know more about the virus and the vaccine. This study demonstrates the need for the development of health communication intervention and more research targeting African American MSMs and also the need for policy change towards making the HPV vaccine routine for males especially adolescents at no cost.

    African American women continue to experience disparities in health status when compared to their European American counterparts, yet, often their unique perspectives are not presented in the nursing literature. This article will discuss various theoretical frameworks arising from Black women's thought and reality that can be used to enhance and expand transcultural nursing knowledge. Historical, sociocultural, and literary perspectives will be used to illuminate the realities of African American women's lives. Selected frameworks arising from these realities will be discussed that recognize the impact of race, class, and gender on the lives of African American women and have the potential to guide nursing research and practice.

    Objective. The aim of the study was to determine the prevalence of HIV-associated oral mucosal melanin hyperpigmentation (HIV-OMH) in a specific population of HIV-seropositive South Africans and to analyse the associations between HIV-OMH clinical features and the demographic and immunological characteristics of the study cohort. Material and Methods. This cross-sectional study included 200 HIV-seropositive Black subjects. The collected data comprised age, gender, CD4+ T cell count, viral load, systemic disease, medications, oral site affected by HIV-OMH, extent (localized or generalized), intensity of the pigmentation (dark or light), and smoking and snuff use. Results. Overall, 18.5% of the study cohort had HIV-OMH. Twenty-two and a half percent had OMH that could not with confidence be attributed to HIV infection, and 59% did not have any OMH. There was a significant but weak association between smoking and the presence of HIV-OMH. Conclusions. The prevalence of HIV-OMH in the study population was 18.5%, the gingiva being the most commonly affected site. It appears that the CD4+ T cell count does not play any role in the biopathology of HIV-OMH. PMID:27006825

    Objective To explore nativity differences and the role of attitudes, social norms, and behavioral control perceptions surrounding breastfeeding initiation and duration among middle-class African-American (AA) and African-born (AB) mothers in the US. Methods Semi-structured individual interviews were conducted with 20 middle-class AA and AB mothers in central Ohio from December 2012 to February 2013. Interview questions were developed based on the Theory of Planned Behavior (TPB). Interviews were analyzed for salient themes by TPB constructs. Differences in themes were examined by nativity status. Results All study participants had initiated breastfeeding or bottle-feeding with expressed breast milk, noting the benefits it conferred as well as the persuasive encouragement they received from others. Persistent encouragement was often cited as a factor for sustaining breastfeeding. More AA mothers had discontinued breastfeeding by the time of the interview, which was often attributed to health, lactation, and work challenges. Inconsistent support from health providers, dissuasive remarks from others, ambivalent breastfeeding attitudes, and diminished family support led some mothers to begin formula supplementation. Analysis of maternal narratives revealed nativity differences across sources of encouragement. Specifically, important sources of encouragement were health providers for AA mothers and family, friends, partners and culture for AB mothers. Only AB mothers expressed concerns about difficulty they encountered with breastfeeding due to the lack of proximal family support. Conclusions Findings reveal that both groups of mothers may be susceptible to unsupportive breastfeeding norms in the US and also highlight the need for intervention in health care settings and workplaces to improve AA women's breastfeeding rates.

    Recently, social scientists have become increasingly interested in the nature of communications from parents to children regarding ethnicity and race. Termed racial socialization, race-related messages to children may have important consequences for children's identity development and well-being. This study examined the frequency and correlates of two dimensions of racial socialization-messages about ethnic pride, history, and heritage (Cultural Socialization) and messages about discrimination and racial bias (Preparation for Bias)--among 273 urban African American, Puerto Rican, and Dominican parents. Parents reported more frequent Cultural Socialization than Preparation for Bias. There were no significant ethnic group differences in the frequency of Cultural Socialization. However, African American parents reported more frequent Preparation for Bias than did Dominican parents who, in turn, reported more frequent messages of this sort than did Puerto Rican parents Ethnic identity was a stronger predictor of Cultural Socialization among Puerto Rican and Dominican parents than among their African American counterparts. In contrast, perceived discrimination experiences was a stronger predictor of Preparation for Bias among African American and Dominican parents than among Puerto Rican parents. Finally, race-related phenomenon accounted for more variance in both Cultural Socialization and Preparation for Bias among parents reporting on their behaviors with children 10-17 years old as compared to parents reporting on their behaviors with children 6-9 years old.

    The biomedical literature contains much speculation about possible genetic explanations for the large and persistent black-white disparities in hypertension, but profound social inequalities are also hypothesized to contribute to this outcome. Our goal is to evaluate whether socioeconomic status (SES) differences provide a plausible mechanism for associations between African ancestry and hypertension in a U.S. cohort of older non-Hispanic blacks. We included only non-Hispanic black participants (N = 998) from the Health and Retirement Study who provided genetic data. We estimated percent African ancestry based on 84,075 independent single nucleotide polymorphisms using ADMIXTURE V1.23, imposing K = 4 ancestral populations, and categorized into quartiles. Hypertension status was self-reported in the year 2000. We used linear probability models (adjusted for age, sex, and southern birth) to predict prevalent hypertension with African ancestry quartile, before and after accounting for a small set of SES measures. Respondents with the highest quartile of African ancestry had 8 percentage points' (RD = 0.081; 95% CI: -0.001, 0.164) higher prevalence of hypertension compared to the lowest quartile. Adjustment for childhood disadvantage, education, income, and wealth explained over one-third (RD = 0.050; 95% CI: -0.034, 0.135) of the disparity. Explanations for the residual disparity remain unspecified and may include other indicators of SES or diet, lifestyle, and psychosocial mechanisms. PMID:27050031

    1998-07-01

    This dissertation utilizes gravity and seismic waveform modeling techniques to: (1) determine models of lithospheric structure across northern African through gravity modeling and (2) determine lithospheric and crustal structure and seismic wave propagation characteristics across northern Africa and the Mediterranean region. The purpose of the gravity investigation was to construct models of lithospheric structure across northern Africa through the analysis of gravity data constrained by previous geological and geophysical studies. Three lithospheric models were constructed from Bouguer gravity data using computer modeling, and the gravity data was wavelength-filtered to investigate the relative depth and extent of the structures associated with the major anomalies. In the Atlas Mountains area, the resulting earth models showed slightly greater crustal thickness than those of previous studies if a low density mantle region is not included in the models. However, if a low density mantle region (density = 3.25 g/cm3) was included beneath the Atlas, the earth models showed little crustal thickening (38 km), in accord with previous seismic studies. The second portion of the research consisted of seismic waveform modeling of regional and teleseismic events to determine crustal and lithospheric structure across northern Africa and the Mediterranean. A total of 174 seismograms (145 at regional distances (200--1400 km) and 29 with epicentral distances exceeding 1900 km) were modeled using 1-D velocity models and a reflectivity code. At regional distances from four stations surrounding the western Mediterranean basin (MAL, TOL, PTO and AQU) and one station near the Red Sea (HLW), 1-D velocity models can satisfactorily model the relative amplitudes of both the Pnl and surface wave portions of the seismograms. Modeling of propagation paths greater than 1900 km was also conducted across northern Africa and the Mediterranean. The results indicate that the S-wave velocity model

    Exposure to racism has been linked to poor health outcomes. Little is known about the impact of racism on diabetes outcomes. This study explored African American (AA) women’s beliefs about how racism interacts with their diabetes self-management and control. Four focus groups were conducted with a convenience sample of 28 adult AA women with type 2 diabetes who were recruited from a larger quantitative study on racism and diabetes. The focus group discussions were transcribed verbatim and analyzed by the authors. Women reported that exposure to racism was a common phenomenon, and their beliefs did in fact link racism to poor health. Specifically, women reported that exposure to racism caused physiological arousal including cardiovascular and metabolic perturbations. There was consensus that physiological arousal was generally detrimental to health. Women also described limited, and in some cases maladaptive, strategies to cope with racist events including eating unhealthy food choices and portions. There was consensus that the subjective nature of perceiving racism and accompanying social prohibitions often made it impossible to address racism directly. Many women described anger in such situations, and the tendency to internalize anger and other negative emotions, only to find that the negative emotions would be reactivated repeatedly with exposure to novel racial stressors, even long after the original racist event remitted. AA women in this study believed that racism affects their diabetes self-management and control. Health beliefs can exert powerful effects on health behaviors and may provide an opportunity for health promotion interventions in diabetes. PMID:21528110

    Background Coronary heart disease remains the leading cause of death in developed countries. In Africa, the disease continues to rise with varying rates of progression in different countries. At present, there is little available work on its juvenile forms. The objective of this work was to study the epidemiological, clinical and evolutionary aspects of acute coronary syndrome in young Sub-Saharan Africans. Methods This was a prospective multicenter study done at the different departments of cardiology in Dakar. We included all patients of age 40 years and below, and who were admitted for acute coronary syndrome between January 1st, 2005 and July 31st, 2007. We collected and analyzed the epidemiological, clinical, paraclinical and evolutionary data of the patients. Results Hospital prevalence of acute coronary syndrome in young people was 0.45% (21/4627) which represented 6.8% of all cases of acute coronary syndrome admitted during the same period. There was a strong male predominance with a sex-ratio (M:F) of 6. The mean age of patients was 34 ± 1.9 years (range of 24 and 40 years). The main risk factor was smoking, found in 52.4% of cases and the most common presenting symptom was chest pain found in 95.2% of patients. The average time delay before medical care was 14.5 hours. Diagnosis of ST- elevation myocardial infarction in 85.7% of patients and non-ST-elevation myocardial infarction in 14.3% was made by the combination electrocardiographic features and troponin assay. Echocardiography found a decreased left ventricular systolic function in 37.5% of the patients and intraventricular thrombus in 20% of them. Thrombolysis using streptokinase was done in 44.4% of the patients with ST- elevation myocardial infarction. Hospital mortality was 14.3%. Conclusion Acute coronary syndrome is present in young Sub-Saharan Africans. The main risk factor found was smoking. PMID:24330283

    The Earth Observing System (EOS) is an integral part of the National Aeronautics and Space Administration's (NASA's) Earth Science Enterprise (ESE). ESE is a long-term global change research program designed to improve our understanding of the Earth's interrelated processes involving the atmosphere, oceans, land surfaces, and polar regions. Data from EOS instruments and other Earth science measurement systems are useful in understanding the causes and processes of global climate change and the consequences of human activities. The EOS Data and Information System (EOSDIS) provides a structure for data management and user services for products derived from EOS satellite instruments and other NASA Earth science data. Within the EOSDIS framework, the Distributed Active Archive Centers (DAACs) have been established to provide expertise in one or more Earth science disciplines. The DAACs and cooperating data centers provide data and information services to support the global change research community. Much of the development of the DAACs has been in anticipation of the enormous amount of data expected from EOS instruments to be launched within the next two decades. Terra, the EOS flagship launched in December 1999, is the first of a series of EOS satellites to carry several instruments with multispectral capabilities. Some data products from these instruments are now available from several of the DAACs. These and other data products can be ordered through the EOS Data Gateway (EDG) and DAAC-specific online ordering systems.

    The purpose of this study was to define the barriers to breastfeeding in the inner city African American adolescent mother. The study was conducted at Johnnie Ruth Clarke Health Center in St. Petersburg, Florida from October 1999 to February 2000. The study population included 25 African American adolescent mothers between the ages of 15 and 21 years. The results indicate that these mothers possess adequate knowledge about the benefits of breast milk. The greatest barriers to breastfeeding included pain, embarrassment, and lack of interest. These concerns are appropriate given their developmental stage; however, interventions are necessary to address these issues.

    The clinical outcome of patients following subarachnoid hemorrhage is complicated by delayed cerebral ischemia and contributing factors such as hypertension. To observe the impact of hypertension and delayed cerebral ischemia on the outcome of a predominantly African-American cohort following subarachnoid hemorrhage, both retrospective (n = 42) and prospective (n = 21) studies were conducted. In the total pool (n = 63), the mean age was 49.7 years (range: 17 to 80) with a preponderance of female patients (70%). Aneurysm formation was significant in the region of the posterior communicating artery. Of the patients reviewed, 73.8% had preexisting hypertension and 45.9% developed delayed cerebral ischemia. Approximately 89% of the patients who suffered from delayed cerebral ischemia had hypertension. Results failed to display any significant beneficial association between the use of the calcium channel blocker nimodipine and delayed cerebral ischemia. Use of the antifibrinolytic drug aminocaproic acid demonstrated a worse patient outcome. It is not recommended that aminocaproic acid be used in this population. Subsequently, due to the proportional occurrence of delayed cerebral ischemia in hypertensive patients following subarachnoid hemorrhage, it is suggested that prophylactic surgical management of unruptured intracranial aneurysms be considered in hypertensive patients. Further study is needed to discern the association between hypertension, delayed cerebral ischemia, and stroke in patients following subarachnoid hemorrhage. PMID:9046763

  16. Political will, traditional leaders and the fight against HIV/AIDS: a South African case study.

    2010-01-01

    "Political will" and leadership are increasingly considered key contextual influences on the outcomes of HIV/AIDS programmes in sub-Saharan Africa. Such debates tend to focus on the role of national leadership in shaping responses to the epidemic, with little attention to local leaders. Yet many of the settings in which HIV/AIDS flourishes are geographically distant from the reach of national leadership and policies. Furthermore, local leaders often play a key role in shaping how national policies and decisions are interpreted and implemented in local areas. Against this background, we present a case study of the impact of the leadership style of a traditional Chief on a community-based AIDS programme in a South African rural community, which sought to build community-level "AIDS competence", using the "empowerment via participation" approach. The case study involved 134 interviews and 57 focus groups conducted over three years. Thematic content analysis revealed a number of direct and indirect ways in which his leadership style impacted on project outcomes. Despite his strong support for the programme, the Chief's "traditional" attitudes towards women and youth, his celebration of polygamy, and his authoritarian governance style undermined the project's "empowerment via participation" agenda - especially the programme's attempts to reduce AIDS stigma, to build female and youth capacity to control their sexual health, and to encourage men to take responsibility for their role in tackling AIDS.

Results Protective resources identified were the family and community capacities that can promote youth psychosocial adjustment through: 1) Finances for necessities; 2) English proficiency; 3) Social support networks; 4) Engaged parenting; 5) Family cohesion; 6) Cultural adherence and guidance; 7) Educational support; and, 8) Faith and religious involvement. The researchers first inductively identified 19 thriving, 29 managing, and 25 struggling youths based on review of cases. Univariate analyses then indicated significant associations with country of origin, parental education, and parental employment. Multiple regressions indicated that better psychosocial adjustment was associated with Liberians and living with both parents. Logistic regressions showed that thriving was associated with Liberians and higher parental education, managing with more parental education, and struggling with Burundians and living parents. Qualitative analysis identified how these factors were proxy indicators for protective resources in families and communities. Conclusion These three trajectories of psychosocial adjustment and six domains of protective resources could assist in developing targeted prevention programs and policies for refugee youth. Further rigorous longitudinal mixed-methods study of adolescent refugees in U.S. resettlement are needed. PMID:24205467

    Background and Aim. Inadequate bowel preparation is a major impediment in colonoscopy quality outcomes. Aim of this study was to evaluate the role of multimedia education (MME) in improving bowel preparation quality and adenoma detection rate. Methods. This was an IRB-approved prospective randomized study that enrolled 111 adult patients undergoing outpatient screening or surveillance colonoscopy. After receiving standard colonoscopy instructions, the patients were randomized into MME group (n = 48) and control group (n = 46). The MME group received comprehensive multimedia education including an audio-visual program, a visual aid, and a brochure. Demographics, quality of bowel preparation, and colonoscopy findings were recorded. Results. MME group had a significantly better bowel preparation in the entire colon (OR 2.65, 95% CI 1.16–6.09) and on the right side of the colon (OR 2.74, 95% CI 1.12–6.71) as compared to control group (p < 0.05). Large polyps (>1 cm) were found more frequently in the MME group (11/31, 35.5% versus 0/13; p < 0.05). More polyps and adenomas were detected in MME group (57 versus 39 and 31 versus 13, resp.) but the difference failed to reach statistical significance. Conclusion. MME can lead to significant improvement in the quality of bowel preparation and large adenoma detection in a predominantly African-American population. PMID:27006590

    Experimental studies in laboratory settings have demonstrated a critical role of parasite interactions in shaping parasite communities. The sum of these interactions can produce diverse effects on individual hosts as well as influence disease emergence and persistence at the population level. A predictive framework for the effects of parasite interactions in the wild remains elusive, largely because of limited longitudinal or experimental data on parasite communities of free-ranging hosts. This 4-year study followed a community of haemoparasites in free-ranging African buffalo (Syncerus caffer). We detected infection by 11 haemoparasite species using PCR-based diagnostic techniques, and analyzed drivers of infection patterns using generalized linear mixed models to understand the role of host characteristics and season on infection likelihood. We tested for (i) effects of co-infection by other haemoparasites (within guild) and (ii) effects of parasites infecting different tissue types (across guild). We found that within guild co-infections were the strongest predictors of haemoparasite infections in the buffalo; but that seasonal and host characteristics also had important effects. In contrast, the evidence for across-guild effects of parasites utilizing different tissue on haemoparasite infection was weak. These results provide a nuanced view of the role of co-infections in determining haemoparasite infection patterns in free living mammalian hosts. Our findings suggest a role for interactions among parasites infecting a single tissue type in determining infection patterns. PMID:27084785

    The Biosphere 2 Laboratory of Biosphere 2 Center, Arizona, is a unique, self-contained glasshouse fostering several mesocosms of tropical and subtropical regions on an area of 12,700 m2. It was constructed around 1990 to test whether human life is possible in this completely sealed, self-sustaining artificial ecosystem. Mainly due to overly rich organic soils, the initial mission failed in a spectacular manner that raised enormous disbelief in the scientific seriousness of the project. From 1995 to 2003, the facility had been operated by Columbia University under a completely new scientific management. The aim of the project had then been to conduct research in the field of 'experimental climate change science'. Climatic conditions within the mesocosms can be precisely controlled. In studies with elevated CO2, altered temperature and irrigation regimes performed in the rainforest, coral reef and agriforestry mesocosm, the facility had proven to be a valuable tool for global climate change research. Upon submission of this manuscript, Columbia University is relinquishing the management of this facility now although there was a contract to operate the facility until 2010, leaving it with an unclear destiny that might bring about anything from complete abandonment to a new flowering phase with a new destination.

    Twenty-first century energy challenges include demand growth, national energy security, and global climate protection. The Center for Advanced Energy Studies (CAES) is a public/private partnership between the State of Idaho and its academic research institutions, the federal government through the U.S. Department of Energy (DOE) and the Idaho National Laboratory (INL) managed by the Battelle Energy Alliance (BEA). CAES serves to advance energy security for our nation by expanding the educational opportunities at the Idaho universities in energy-related areas, creating new capabilities within its member institutions, and delivering technological innovations leading to technology-based economic development for the intermountain region. CAES has developed this strategic plan based on the Balanced Scorecard approach. A Strategy Map (Section 7) summarizes the CAES vision, mission, customers, and strategic objectives. Identified strategic objectives encompass specific outcomes related to three main areas: Research, Education, and Policy. Technical capabilities and critical enablers needed to support these objectives are also identified. This CAES strategic plan aligns with and supports the strategic objectives of the four CAES institutions. Implementation actions are also presented which will be used to monitor progress towards fulfilling these objectives.

  3. Infrared studies of galactic center x-ray sources

    DeWitt, Curtis

    In this dissertation I use a variety of approaches to discover the nature of a subset of the nearly 10,000 X-ray point sources in the 2° x 0.8° region around the Galactic Center. I produced a JHK s source catalog of the 170 x170 region around Sgr A* an area containing 4339 of these X-ray sources, with the ISPI camera on the CTIO 4-m telescope. I cross-correlated the Chandra and ISPI catalogs to find potential near-infrared (NIR) counterparts to the X-ray sources. The extreme NIR source crowding in the field means that it is not possible to establish the authenticity of the matches with astrometry and photometry alone. I found 2137 IR/X-ray astrometrically matched sources; statistically I calculated that my catalog contains 289+/-13 true matches to soft X-ray sources and 154 +/- 39 matches to hard X-ray sources. However, the fraction of matches to hard sources that are spurious is 90%, compared to 40% for soft source matches, making the hard source NIR matches particularly challenging for spectroscopic follow-up. I statistically investigated the parameter space of matched sources and identified a set of 98 NIR matches to hard X-ray sources with reddenings consistent with the GC distance which have a 45% probability of being true counterparts. I created two additional photometric catalogs of the GC region to investigate the variability of X-ray counterparts over a time baseline of several years. I found 48 variable NIR sources matched to X-ray sources, with 2 spectroscopically confirmed to be true counterparts (1 in previous literature and one in this study). I took spectra of 46 of my best candidates for counterparts to X-ray sources toward the GC, and spectroscopically confirmed 4 sources as the authentic physical counterpart on the basis of emission lines in the H and K band spectra. These sources include a Be high mass X-ray binary located 16 pc in projection away from Sgr A*; a hard X-ray symbiotic binary located 22 pc in projection from Sgr A*; an O

    Bellevue Hospital, the oldest public hospital in the United States and a lineal descendant of an infirmary for slaves, accepted its first African-American resident, Dr. Ubert Conrad Vincent, in 1918. This occurred at a time when many medical centers were not accepting African-American residents. At the end of WWII, one-third of the accredited medical schools still barred African Americans. However, Bellevue Hospital continued to train African-American residents. Between the 1920s and 1940s four African Americans matriculated at Bellevue Hospital. There were six in the 1950s, four in the 1960s, and 25 in the 1970s. By the 1980s, 40 African Americans matriculated, and between 1990 and 1995, 61 matriculated. Despite its historic first, Bellevue lagged slightly behind the national average. While the number of African-American residents occupying U.S. residency slots increased from 2.8% in 1978 to 6.5% in 1996, African Americans comprised 3.6% of residency slots at Bellevue between 1985-1995. Currently, only 7% of practicing physicians and 5% in faculty positions are latino, African-American, and Native American. Increasing the number of under-represented minority (URM) physicians is important to the United States, as URM physicians are more likely to serve the poor and uninsured, therefore improving the overall healthcare of the underprivileged. A study by the Association of American Medical Colleges indicated that minority medical school graduates were five times more likely to report that they planned to serve minority populations than other graduates. In their position paper, the American College of Physicians expressed the belief that increasing the number of URM physicians will help reduce healthcare disparities that can hurt minority populations and lead to poor health outcomes. The Supreme Court acknowledged the importance of racial diversity by upholding the University of Michigan affirmative action admissions policy in its June 2003 ruling. URM physicians are

    Background It is now widely accepted that climate change is occurring as a result of the accumulation of greenhouse gases (GHG) in the atmosphere. With the prospect of a warmer world, increased attention is being devoted to the implications for worker well-being and work performance. Objectives The ‘high occupational temperature health and productivity suppression’ (HOTHAPS) programme is a multi-centre health research and prevention programme aimed at characterising and quantifying the extent to which working people are affected by, or adapt to, heat exposure while working. The main aim of the current South African pilot study was to look at the perceptions of outdoor workers regarding their work environment in hot weather and how this affected their health and productivity levels. Design A qualitative study utilising focus group discussions was employed in two sites, Johannesburg (which has a temperate climate) and Upington (located in the hottest part of South Africa). Results In summary, the pilot study demonstrated that especially in Upington, where daily maximum temperatures may reach +40°C, workers reported a wide range of heat-related effects, including sunburn, sleeplessness, irritability, and exhaustion leading to difficulty in maintaining work levels and output during very hot weather. Few, if any, measures were being undertaken by employers to protect health or improve worker comfort. Conclusion This pilot study has demonstrated that people working in sun-exposed conditions in hot parts of South Africa currently experience heat-related health effects, with implications for their well-being and ability to work and that further research is warranted. In this regard, the pilot study has proved valuable in informing the design, site, sample selection, and logistical planning for a proposed main study on the health and performance aspects of work in hot weather in South Africa.

    Caregiver-youth communication about sex protects youth against HIV/AIDS, and caregivers who believe that sex knowledge is important are more likely to talk to their youth about sex. However, caregivers who experience barriers to communication about sex may not talk to their youth about sex even if the caregiver believes that sex education is important. The Theory of Planned Behaviour predicts that an actor has perceived control is necessary for behavioural change. This study therefore hypothesised that caregivers' perceived control moderates the relationship between caregiver attitudes about youth sex knowledge and caregiver-youth communication about sex. Results from a sample of 99 female South African caregivers of adolescent (10-14 year old) youth supported our hypothesis, indicating that caregiver attitudes about providing youth with sex knowledge positively predict communication about sex only when caregivers have perceived control. This finding illustrates the importance of perceived control in predicting caregiver-youth communication, and therefore has implications for family-based interventions aimed at improving caregiver-youth communication about sex.

    Conserving crop wild relatives (CWR) is critical for maintaining food security. However, CWR-focused conservation plans are lacking, and are often based on the entire genus, even though only a few taxa are useful for crop improvement. We used taxonomic and geographic prioritisation to identify the best locations for in situ conservation of the most important (priority) CWR, using African cowpea (Vigna unguiculata (L.) Walp.) as a case study. Cowpea is an important crop for subsistence farmers in sub-Saharan Africa, yet its CWR are under-collected, under-conserved and under-utilised in breeding. We identified the most efficient sites to focus in situ cowpea CWR conservation and assessed whether priority CWR would be adequately represented in a genus-based conservation plan. We also investigated whether priority cowpea CWR are likely to be found in existing conservation areas and in areas important for mammal conservation. The genus-based method captured most priority CWR, and the distributions of many priority CWR overlapped with established conservation reserves and targets. These results suggest that priority cowpea CWR can be conserved by building on conservation initiatives established for other species.

    2008-03-01

    Intelligent Transport Systems (ITS) can facilitate the delivery of a wide range of policy objectives. There are six main objectives/benefits identified in the international literature: Safety (reduction of (potential) crashes), mobility (reduction of delays and travel times), efficiency (optimise the use of existing infrastructure), productivity (cost saving), energy/environment and customer satisfaction [Mitretek Systems, 2001. Intelligent Transport System Benefits: 2001 update, Under Contract to the Federal Highway Administration, US Department of Transportation, Washington, DC, US]. In the South African context, there is an interest for measures that can reduce (potential) crashes. In South Africa the number of year on year traffic related fatalities is still increasing. In 2005 the number of fatalities was 15393 (from 14135 in 2004) while the estimated costs for the same period increased from R8.89-billion to R9.99-billion [RTMC, 2007. Interim Road Traffic and Fatal Crash Report 2006, Road Traffic Management Corporation, Pretoria, SA]. Given the extent of the road safety problem and the potential benefits of ITS, the need for further research is apparent. A study with regards to the potential of different types of models (macroscopic, mesoscopic and miscroscopic simulation models) led to the use of Paramics. Two corridors and three types of ITS measures were investigated and safety benefits were estimated.

    Efficient plant regeneration of Saintpaulia ionantha (African violet) has been obtained in the present study. MS medium supplemented with 1.0 mg L(-1) IAA and 2.0 mg L(-1) Zeatin resulted in 100% shoot regeneration and induced the highest number of shoots (average 15.0 +/- 0.8 shoots per explant) after being cultured for 8 weeks. The above hormone combination was optimum for shoot regeneration. Most of Saintpaulia ionantha plantlets derived from tissue culture system could be hardened and transferred to the greenhouse conditions with 84.0 +/- 1.6% success rate. However, regenerated plantlets of Saintpaulia ionantha (even after 12-months-old) failed to flower. Morphological characters of regenerated plantlets of Saintpaulia ionantha were observed and compared with in vivo (intact) plants. Regenerated plantlets showed some differences in morphological characters, such as height and leaf size, texture and colour, but the plantlets showed no variation in leaf arrangement and leaf margin. However, the morphological characters of the regenerated plantlets were found to be unstable. PMID:18819532

    Purpose: To investigate African-American fathers’ (AAF) perceptions regarding the applicability and need for their involvement as a health connection for their children and describe how participating fathers’ behavior was affected by their attitudes, knowledge, and perceptions of their influence on their children’s health. Methods: This exploratory study gathered data via semi-structured focus groups (n = 3) and thematically analyzed it utilizing a grounded theory approach. Participants included AAF (n = 20) with a mean age of 37 years (SD 11.79), with at least one child between 6 and 18 years old. Results: Four major themes were revealed: (1) appropriate health education for participants’ children (should first and foremost be delivered by parents); (2) participants’ paternal health-related guidance approach (reactive, rather than proactive); (3) participants’ perceived influences on health-related communication with their children (gender roles, efficacy constraints); and (4) paternal definitions of health (most often associated with diet). Conclusion: Understanding AAFs’ perceived and desired role in their children’s health edification can inform initiatives that actively engage these men, and nurture their level of involvement, to promote positive health behaviors among their children; this is necessary to realize their potential to actively improve the health of their children, families, and communities.

    Sepsis is the combination of infection and physiological changes known as the systemic inflammatory response syndrome. There have been improvements in mortality rates and outcomes of septic patients based on "Surviving Sepsis Campaign" guidelines. Current management of sepsis at our Institution follows no specific mandatory protocols. This study aimed to verify the incidence and outcome of sepsis in Manati Medical Center, Puerto Rico. An observational retrospective study was conducted. All the Emergency Department admissions from May 1/ to October 31/ 2013 were screened for sepsis per ICD-9 code. For all included patients, demographic and clinical data at ED admission were collected. During this period 8931 patients were admitted and 148 met criteria for sepsis and related conditions. The overall mortality rate was 43.91%. Mortality increased with age, from 10.52% among ≤ 44 years old to 68.75% in those ≥ 85 years old. The main infection sources were respiratory (32.66%) and urinary tract (24.62%). Mean age among non-survivors was 10.8 years higher than the survivor group (95% Cl 5.2-1 6.5, p < 0.05). Multivariate analysis showed an increased fatality rate associated to severity of sepsis (HR 1.33; 95% Cl; 1.03-1.72, p = 0.02) and the APACHE2 score (HR 1.05; 95% Cl, 1.01-1.09 p = 0.03). Our data suggests that sepsis is an important problem to consider. We strongly encourage an institutional standardized protocol to diminish the mortality impact. Our results will allow adequate preventive strategies to improve early diagnosis, mortality rates and outcomes of septic patients.

    The first phase of the Flint Men's Health Study (FMHS) in Michigan was a community-based epidemiologic study of prostate cancer and benign prostatic hyperplasia (BPH) in African-Americans aged 40 to 79 years. An objective of the FMHS was to determine age-specified prostate specific antigen (PSA) reference ranges in a random population sample of African-American men without clinically evident prostate cancer. The FMHS study protocol included an initial in-home epidemiologic interview followed by PSA testing and a urologic examination of eligible subjects. Since the participation rate in the PSA phase of the study was under 60%, it was important to determine whether selectivity in participation biased the FMHS results for age-specific PSA distributions. Logistic regression analyses were used to investigate selectivity in the sample of subjects who participated in the PSA testing and urologic examination. Younger men, with current urologic symptoms, and with a family history of prostate cancer were more likely to participate in the PSA testing and urologic examination. Linear regression analysis indicated that greater participation by African-American men without clinically evident prostate cancer but with obstructive or irritative lower urinary tract symptoms or a family history of prostate cancer did not bias the estimated age-specific reference ranges for total PSA concentrations and free-to-total PSA ratios.

    Purpose. We determined if quantitative measurements of biogeographic ancestry (BGA) correlate with variations in optic disc area, corneal thickness (CCT), and retinal nerve fiber layer (RNFL) thickness. Methods. Data were obtained from 656 participants in the African Descent and Glaucoma Evaluation Study (ADAGES) cohort who consented to BGA testing. Data for CCT, optic disc area, and RNFL thickness were obtained from subjects in the ADAGES study who also had participated in the current substudy. A total of 31 ancestry informative markers (AIMs) with large allele frequencies differences between populations was used to calculate admixture proportion (implemented in STRUCTURE). Correlations with BGA adjusted for diagnosis, age, and sex for CCT and optic disc area using the whole group and RNFL thickness adjusted for age and sex for the normal study participants were determined. Results. The mean percentage of African admixture was 79.6% in the self-described African Descent (AD) group and 3.5% in the European Descent (ED) group. Percent African ancestry was significantly correlated with CCT (ρ = −0.27, P < 0.0001) and disc area (ρ = 0.15, P < 0.0001), but only marginally associated with RNFL thickness (ρ = 0.20, P = 0.092) in adjusted models. Conclusions. The BGA correlates with variation in ocular features that significantly differ across racial groups and that have been associated with the development of glaucoma. While BGA can provide an objective measurement of the biologic component of self-described race for ocular research, for most nongenetic epidemiologic studies, self-described race may adequately describe the associations with these ocular characteristics.

    Youth violence in African American communities is still considered to be at epidemic proportions. The traditional risk factors for youth violence (i.e. delinquent friends, poverty, drug use, carrying a weapon etc.) do not account for the disproportionate overrepresentation of African American males. This study sought to better understand the propensity for violence among African American males ages 14-19 years (N=224) from four different programmatic sites: a Philadelphia high school, an African-centered charter high school, a youth detention facility, and a program that serves youth who are on probation or parole. The findings indicate that internalized racism enhances the variance explained above the variables typically explored in the delinquency and criminology literature. If further research can replicate these findings, this has implications for the content and direction of prevention approaches with African American male youth.

    The purpose of this study is to gain an in-depth understanding of African American breast cancer survivors' experiences, barriers and facilitators in accessing breast cancer treatment, and challenges in adherence to follow-up care. We conducted seven focus groups with 32 African American women with breast cancer in three rural counties in eastern North Carolina during August-November 2013. Surveys were also utilized to gather basic demographic and breast health history information. Thematic analysis was performed using the immersion crystallization approach. Several common areas of life affected by breast cancer included faith and support networks, psychosocial well-being, and quality of care issues. Faith in God was an important coping mechanism essential to all women in the study and a critical facilitator in survivorship. Support networks consisted of family, church-family, friends, and co-workers. The concept of fear included the discovery of breast cancer and fear of death, negative side effects of treatment, and social stigma of having breast cancer. Factors that influenced provider-patient relationship were age of provider, perceived lack of empathy, and providers leaving during treatment. Participants also expressed their lack of knowledge regarding a number of the side effects they were experiencing during and after their treatment. Results of this study contribute to the assessment of potential coping mechanisms used by African American breast cancer survivors (i.e., spirituality, positive attitudes, and support networks) that can potentially be effective and have a positive impact on the adjustment of life for survivors.

    Cigarette smoking has been shown to be a health hazard. In addition to being considered a negative lifestyle behavior, studies have shown that cigarette smoking has been linked to genetic underpinnings of hypertension. Because African Americans have the highest incidence and prevalence of hypertension, we examined the joint effect of genetics and cigarette smoking on health among this understudied population. The sample included African Americans from the genome wide association studies of HyperGEN (N = 1083, discovery sample) and GENOA (N = 1427, replication sample), both part of the FBPP. Results suggested that 2 SNPs located on chromosomes 14 (NEDD8; rs11158609; raw p = 9.80 × 10−9, genomic control-adjusted p = 2.09 × 10−7) and 17 (TTYH2; rs8078051; raw p = 6.28 × 10−8, genomic control-adjusted p = 9.65 × 10−7) were associated with SBP including the genetic interaction with cigarette smoking. These two SNPs were not associated with SBP in a main genetic effect only model. This study advances knowledge in the area of main and joint effects of genetics and cigarette smoking on hypertension among African Americans and offers a model to the reader for assessing these risks. More research is required to determine how these genes play a role in expression of hypertension. PMID:26752167

    African-American (AA) women have earlier menarche on average than women of European ancestry (EA), and earlier menarche is a risk factor for obesity and type 2 diabetes among other chronic diseases. Identification of common genetic variants associated with age at menarche has a potential value in pointing to the genetic pathways underlying chronic disease risk, yet comprehensive genome-wide studies of age at menarche are lacking for AA women. In this study, we tested the genome-wide association of self-reported age at menarche with common single-nucleotide polymorphisms (SNPs) in a total of 18 089 AA women in 15 studies using an additive genetic linear regression model, adjusting for year of birth and population stratification, followed by inverse-variance weighted meta-analysis (Stage 1). Top meta-analysis results were then tested in an independent sample of 2850 women (Stage 2). First, while no SNP passed the pre-specified P < 5 × 10(-8) threshold for significance in Stage 1, suggestive associations were found for variants near FLRT2 and PIK3R1, and conditional analysis identified two independent SNPs (rs339978 and rs980000) in or near RORA, strengthening the support for this suggestive locus identified in EA women. Secondly, an investigation of SNPs in 42 previously identified menarche loci in EA women demonstrated that 25 (60%) of them contained variants significantly associated with menarche in AA women. The findings provide the first evidence of cross-ethnic generalization of menarche loci identified to date, and suggest a number of novel biological links to menarche timing in AA women.

    Introduction Group A β-haemolytic Streptococcus (GAS), a Gram-positive bacterium, also known as Streptococcus pyogenes, causes pyoderma, pharyngitis and invasive disease. Repeated GAS infections may lead to autoimmune diseases such as acute post-streptococcal glomerulonephritis, acute rheumatic fever (ARF) and rheumatic heart disease (RHD). Invasive GAS (iGAS) disease is an important cause of mortality and morbidity worldwide. The burden of GAS infections is, however, unknown in Africa because of lack of surveillance systems. Methods and analysis The African group A streptococcal infection registry (the AFROStrep study) is a collaborative multicentre study of clinical, microbiological, epidemiological and molecular characteristics for GAS infection in Africa. The AFROStrep registry comprises two components: (1) active surveillance of GAS pharyngitis cases from sentinel primary care centres (non-iGAS) and (2) passive surveillance of iGAS disease from microbiology laboratories. Isolates will also be subjected to DNA isolation to allow for characterisation by molecular methods and cryopreservation for long-term storage. The AFROStrep study seeks to collect comprehensive data on GAS isolates in Africa. The biorepository will serve as a platform for vaccine development in Africa. Ethics and dissemination Ethics approval for the AFROStrep registry has been obtained from the Human Research Ethics Committee at the University of Cape Town (HREC/REF: R006/2015). Each recruiting site will seek ethics approval from their local ethics’ committee. All participants will be required to provide consent for inclusion into the registry as well as for the storage of isolates and molecular investigations to be conducted thereon. Strict confidentiality will be applied throughout. Findings and updates will be disseminated to collaborators, researchers, health planners and colleagues through peer-reviewed journal articles, conference publications and proceedings. PMID:26916694

    Background: Compared with European Americans, African Americans (AAs) exhibit lower levels of the cardio-metabolically protective adiponectin even after accounting for adiposity measures. Because few studies have examined in AA the association between adiponectin and genetic admixture, a dense panel of ancestry informative markers (AIMs) was used to estimate the individual proportions of European ancestry (PEA) for the AAs enrolled in a large community-based cohort, the Jackson Heart Study (JHS). We tested the hypothesis that plasma adiponectin and PEA are directly associated and assessed the interaction with a series of cardio-metabolic risk factors. Methods: Plasma specimens from 1439 JHS participants were analyzed by ELISA for adiponectin levels. Using pseudo-ancestral population genotype data from the HapMap Consortium, PEA was estimated with a panel of up to 1447 genome-wide preselected AIMs by a maximum likelihood approach. Interaction assessment, stepwise linear and cubic multivariable-adjusted regression models were used to analyze the cross-sectional association between adiponectin and PEA. Results: Among the study participants (62% women; mean age 48 ± 12 years), the median (interquartile range) of PEA was 15.8 (9.3)%. Body mass index (BMI) (p = 0.04) and insulin resistance (p = 0.0001) modified the association between adiponectin and PEA. Adiponectin was directly and linearly associated with PEA (β = 0.62 ± 0.28, p = 0.03) among non-obese (n = 673) and insulin sensitive participants (n = 1141; β = 0.74 ± 0.23, p = 0.001), but not among those obese or with insulin resistance. No threshold point effect was detected for non-obese participants. Conclusions: In a large AA population, the individual proportion of European ancestry was linearly and directly associated with plasma adiponectin among non-obese and non insulin-resistant participants, pointing to the interaction of genetic and metabolic factors influencing adiponectin levels.

    This qualitative study is about barriers to the utilization of HIV testing as perceived by African Americans who have recently used cocaine and who live in the rural Delta region of Arkansas. Affordability, physical accessibility, and geographic availability were not perceived as barriers to HIV testing in this sample, yet acceptability was still perceived as poor. Acceptability due to social mores and norms was a major barrier. Many said testing was unacceptable because of fear of social costs. Many were confident of being HIV-negative based on risky assumptions about testing and the notification process. Small-town social and sexual networks added to concerns about reputation and risk. System approaches may fail if they focus solely on improving access to HIV services but do not take into consideration deeply internalized experiences of rural African Americans as well as involvement of the community in developing programs and services.

    In this study, extended -range (30 -day) high-resolution simulations with the NASA global mesoscale model are conducted to simulate the initiation and propagation of six consecutive African easterly waves (AEWs) from late August to September 2006 and their association with hurricane formation. It is shown that the statistical characteristics of individual AEWs are realistically simulated with larger errors in the 5th and 6th AEWs. Remarkable simulations of a mean African easterly jet (AEJ) are also obtained. Nine additional 30 -day experiments suggest that although land surface processes might contribute to the predictability of the AEJ and AEWs, the initiation and detailed evolution of AEWs still depend on the accurate representation of dynamic and land surface initial conditions and their time -varying nonlinear interactions. Of interest is the potential to extend the lead time for predicting hurricane formation (e.g., a lead time of up to 22 days) as the 4th AEW is realistically simulated.

    Cardiovascular disease (CVD), including heart failure, is a major cause of morbidity and mortality, particularly among African Americans. Exposure to ambient air pollution, such as that produced by vehicular traffic, is believed to be associated with heart failure, possibly by impairing cardiac function. We evaluated the cross-sectional association between residential proximity to major roads, a marker of long-term exposure to traffic-related pollution, and echocardiographic indicators of left and pulmonary vascular function in African Americans enrolled in the Jackson Heart Study (JHS): left ventricular ejection fraction, E-wave velocity, isovolumic relaxation time, left atrial diameter index, and pulmonary artery systolic pressure. We examined these associations using multivariable linear or logistic regression, adjusting for potential confounders. Of 4866 participants at study enrollment, 106 lived <150 m, 159 lived 150–299 m, 1161 lived 300–999 m, and 3440 lived ≥1000 m from a major roadway. We did not observe any associations between residential distance to major roads and these markers of cardiac function. Results were similar with additional adjustment for diabetes and hypertension, when considering varying definitions of major roadways, or when limiting analyses to those free from cardiovascular disease at baseline. Overall, we observed little evidence that residential proximity to major roads was associated with cardiac function among African Americans. PMID:27304962

  1. Biology, literacy, and the African American voice: A case study of meaningful learning in the biology classroom

    NASA Astrophysics Data System (ADS)

    Reese, Keturah

    Under the direction of Sharon Murphy Augustine, Ph.D./Ph.D Curriculum and Instruction There was a substantial performance gap among African Americans and other ethnic groups. Additionally, African American students in a Title I school were at a significantly high risk of not meeting or exceeding on performance tests in science. Past reports have shown average gains in some subject areas, and declines in others (NCES, 2011; GADOE, 2012). Current instructional strategies and the lack of literacy within the biology classroom created a problem for African American high school students on national and state assessments. The purpose of this study was to examine the perceptions of African American students and teachers in the context of literacy and biology through the incorporation of an interactive notebook and other literacy strategies. The data was collected three ways: field notes for a two week observation period within the biology classroom, student and teacher interviews, and student work samples. During the observations, student work collection, and interviews, I looked for the following codes: active learning, constructive learning, collaborative learning, authentic learning, and intentional learning. In the process of coding for the pre-determined codes, three more codes emerged. The three codes that emerged were organization, studying/student ownership, and student teacher relationships. Students and teachers both solidified the notion that literacy and biology worked well together. The implemented literacy strategies were something that both teachers and students appreciated in their learning of biology. Overall students and teachers perceived that the interactive notebook along Cornell notes, Thinking maps, close reads, writing, lab experiments, and group work created meaningful learning experiences within the biology classroom.

    Objective Large body size has been associated with decreased risk of breast cancer in premenopausal, but with increased risk in postmenopausal women. Limited information is available about African American women and differences by estrogen- and progesterone-receptor (ERPR) status. Methods We analyzed data from the Women's Contraceptive and Reproductive Experiences (CARE) Study among 3,997 white and African American breast cancer case patients diagnosed in 1994-98 and 4,041 control participants aged 35 to 64. We calculated multivariate odds ratios (ORs) as measures of relative risk of breast cancer associated with self-reported body mass index (BMI) at age 18 and 5 years before diagnosis (recent BMI). Results Risk tended to decrease with increasing BMI at age 18 in all women (ORBMI≥25 kg/m2 vs <20kg/m2=0.76, 95% CI:0.63–0.90, Ptrend=0.005) and with recent BMI in premenopausal women (ORBMI ≥35 kg/m2 vs <25kg/m2=0.81, 95% CI:0.61–1.06, Ptrend=0.05), unmodified by race. Among postmenopausal white but not African American women, there was an inverse relation between recent BMI and risk. High recent BMI was associated with increased risk of ERPR positive tumors among postmenopausal African American women (ORBMI ≥35 kg/m2 vs <25kg/m2=1.83, 95% CI:1.08–3.09, Ptrend=0.03). Conclusion Among women at age 35-64, BMI at age 18 is inversely associated with risk of breast cancer, but association with recent BMI varies by menopause status, race and hormone receptor status. Impact Our findings indicate that studies of BMI and breast cancer should consider breast cancer subtypes. PMID:20501755

    The literature currently contains no comprehensive sex education (CSE) interventions targeting the African immigrant population. African immigrant mothers have been inhibited by several factors from providing their daughters with CSE. The primary aim of this study was to identify attitudes and beliefs of Sub-Saharan immigrant mothers living in the United States towards providing comprehensive sex education to their daughters aged 12-17 years. The study utilized a one-time anonymous nine-question survey. Fifteen women who met the inclusion criteria completed the study survey online or via paper format. African immigrant mothers are willing to allow comprehensive sex to be taught in schools and at home. Accepted education appears to range from religious and moral teaching to some factual information. This research will potentially assist in the designing of more culturally appropriate comprehensive sex education programs for African immigrant mothers and their daughters.

    The objective of this study was to investigate the influence of caregiver education level on children's dental caries mediated by both caregiver and child oral health behaviors. Participants were 423 low-income African American kindergarteners and their caregivers who were part of a school-based randomized clinical trial. Path analysis tested the hypothesis that caregiver education level affected untreated dental caries and cumulative overall caries experience (decayed or filled teeth) through the mediating influence of frequency of dental visits, use of routine care, and frequency of toothbrushing for both the caregiver and the child. The results supported the hypothesis: caregivers who completed high school were 1.76 times more likely to visit dentists compared with those who did not complete high school (e(0.56) = 1.76, 95% CI: 1.03-2.99), which in turn was associated with 5.78 times greater odds of dental visits among their children (e(1.76) = 5.78, 95% CI: 3.53-9.48). Children's dental visits, subsequently, were associated with 26% fewer untreated decayed teeth compared with children without dental visits (e(-0.31) = 0.74, 95% CI: 0.60-0.91). However, this path was not present in the model with overall caries experience. Additionally, caregiver education level was directly associated with 34% less untreated decayed teeth (e(-0.42) = 0.66, 95% CI: 0.54-0.79) and 28% less decayed or filled teeth (e(-0.32) = 0.72, 95% CI: 0.60-0.88) among the children. This study overcomes important conceptual and analytic limitations in the existing literature. The findings confirm the role of caregiver education in child dental caries and indicate that caregiver's behavioral factors are important mediators of child oral health.

Participants were 423 low-income African American kindergarteners and their caregivers who were part of a school-based randomized clinical trial. Path analysis tested the hypothesis that caregiver education level affected untreated dental caries and cumulative overall caries experience (decayed or filled teeth) through the mediating influence of frequency of dental visits, use of routine care, and frequency of toothbrushing for both the caregiver and the child. The results supported the hypothesis: caregivers who completed high school were 1.76 times more likely to visit dentists compared with those who did not complete high school (e(0.56) = 1.76, 95% CI: 1.03-2.99), which in turn was associated with 5.78 times greater odds of dental visits among their children (e(1.76) = 5.78, 95% CI: 3.53-9.48). Children's dental visits, subsequently, were associated with 26% fewer untreated decayed teeth compared with children without dental visits (e(-0.31) = 0.74, 95% CI: 0.60-0.91). However, this path was not present in the model with overall caries experience. Additionally, caregiver education level was directly associated with 34% less untreated decayed teeth (e(-0.42) = 0.66, 95% CI: 0.54-0.79) and 28% less decayed or filled teeth (e(-0.32) = 0.72, 95% CI: 0.60-0.88) among the children. This study overcomes important conceptual and analytic limitations in the existing literature. The findings confirm the role of caregiver education in child dental caries and indicate that caregiver's behavioral factors are important mediators of child oral health. PMID:25661111

    Background Very little is known about the long-term outcomes of African American living kidney donors (AALKDs). We undertook this study to describe renal outcomes of AALKDs several years after donation. Methods We invited 107 AALKDs to come for follow-up health evaluation. Results 39 subjects (36.4%) completed evaluation at a mean of 7.1 +/− 1.6 (range 3.9–10.2) years post-donation. The mean estimated glomerular filtration rate using the abbreviated MDRD equation (eGFR(MDRD)) at followup was 72.1 +/− 16.3 (range 42–106) ml/min per 1.73m2, and 18% of subjects had an eGFR(MDRD) of 30–59. The mean absolute and relative decrease in eGFR(MDRD) from the time of donation to followup were 30.5 +/− 16.4 ml/min per 1.73m2 and 28.8%, respectively. Subjects whose BMI was ≥ 35 kg/m2 (n=8) were found to have a greater decrement in e(MDRD) than those with BMI < 35 kg/m2 (40.1 +/− 7.3 and 28.3 +/− 17.1 ml/min per 1.73m2, respectively; p = 0.009). Sixteen (41%) were hypertensive at followup, as defined as treatment with antihypertensive medications (n=8) or average BP of ≥140 systolic or 90 mmHg diastolic (n=10, of whom 2 were on antihypertensive medications). One subject had macroalbuminuria (> 300 mcg/mg creatinine), and 6 (15.4%) had microalbuminuria (30–300 mcg/mg creatinine). Conclusions AALKDs experience a substantial incidence of hypertension and a modest drop in eGFR(MDRD) post-donation, and obesity may increase the magnitude of renal decline. Further study is urgently needed to determine the long-term risks of AALKDs. PMID:20029333

    2005-05-08

    The Rhode Island Nuclear Science Center (RINSC), located on the Narragansett Bay Campus of the University of Rhode Island, is a state-owned and US NRC-licensed nuclear facility constructed for educational and industrial applications. The main building of RINSC houses a two-megawatt (2 MW) thermal power critical reactor immersed in demineralized water within a shielded tank. As its original design in 1958 by the Rhode Island Atomic Energy Commission focused on the teaching and research use of the facility, only a minimum of 3.85 kg fissile uranium-235 was maintained in the fuel elements to allow the reactor to reach a critical state. In 1986 when RINSC was temporarily shutdown to start US DOE-directed core conversion project for national security reasons, all the U-Al based Highly-Enriched Uranium (HEU, 93% uranium-235 in the total uranium) fuel elements were replaced by the newly developed U{sub 3}Si{sub 2}-Al based Low Enriched Uranium (LEU, {le}20% uranium-235 in the total uranium) elements. The reactor first went critical after the core conversion was achieved in 1993, and feasibility study on the core upgrade to accommodate Boron Neutron-Captured Therapy (BNCT) was completed in 2000 [3]. The 2-MW critical reactor at RINSC which includes six beam tubes, a thermal column, a gamma-ray experimental station and two pneumatic tubes has been extensive utilized as neutron-and-photon dual source for nuclear-specific research in areas of material science, fundamental physics, biochemistry, and radiation therapy. After the core conversion along with several major system upgrade (e.g. a new 3-MW cooling tower, a large secondary piping system, a set of digitized power-level instrument), the reactor has become more compact and thus more effective to generate high beam flux in both the in-core and ex-core regions for advance research. If not limited by the manpower and operating budget in recent years, the RINSC built ''in concrete'' structure and control systems should have

    This paper examined the relationships between the experiences and perceptions of racism and the physical and mental health status of African Americans. The study was based upon thirteen year (1979 to 1992), four wave, national panel data (n = 623) from the National Survey of Black Americans. Personal experiences of racism were found to have both adverse and salubrious immediate and cumulative effects on the physical and mental well-being of African Americans. In 1979-80, reports of poor treatment due to race were inversely related to subjective well-being and positively associated with the number of reported physical health problems. Reports of negative racial encounters over the 13-year period were weakly predictive of poor subjective well-being in 1992. A more general measure of racial beliefs, perceiving that whites want to keep blacks down, was found to be related to poorer physical health in 1979-80, better physical health in 1992, and predicted increased psychological distress, as well as, lower levels of subjective well-being in 1992. In conclusion, the authors suggested future research on possible factors contributing to the relationship between racism and health status among African Americans.

    2011-01-01

    The efficacy of the current instrument to assess the social assistance needs of children with chronic health conditions in South Africa is questioned. To develop an improved assessment instrument for South African use, this instrument was pitted against two international social assistance assessment instruments, the United Kingdom (UK) Disability Living Allowance (DLA) and the Australian Child Disability Assessment Tool (CDAT). A purposive sample of 18 children representing six types of disability and chronic illnesses was selected, and all three assessment instruments were used to assess the needs of these children. A juxtaposition of the outcomes of the assessment instruments revealed significant differences. The South African instrument deemed the majority (56%) of the sample ineligible for assistance. On the contrary, significant majorities were deemed eligible for assistance in terms of the U.K. (94%) and Australian (89%) instruments. The study recommended that a holistic approach to need assessment be adopted in the design of a more appropriate assessment instrument for South African use. PMID:22085325

    Background Using Jackson Heart Study data, we examined associations of multiple measures of perceived discrimination with health behaviors among African Americans (AA). Methods The cross-sectional associations of everyday, lifetime, and burden of discrimination with odds of smoking and mean differences in physical activity, dietary fat, and sleep were examined among 4,939 35–84 year old participants after adjustment for age and socioeconomic status (SES). Results Men reported slightly higher levels of everyday and lifetime discrimination than women and similar levels of burden of discrimination as women. After adjustment for age and SES, everyday discrimination was associated with more smoking and a greater percentage of dietary fat in men and women (OR for smoking: 1.13, 95%CI 1.00,1.28 and 1.19, 95%CI 1.05,1.34; mean difference in dietary fat: 0.37, p<.05 and 0.43, p<.01, in men and women, respectively). Everyday and lifetime discrimination were associated with fewer hours of sleep in men and women (mean difference for everyday discrimination: −0.08, p<.05 and −0.18, p<.001, respectively; and mean difference for lifetime discrimination: −0.08, p<.05, and −0.24, p<.001, respectively). Burden of discrimination was associated with more smoking and fewer hours of sleep in women only. Conclusions Higher levels of perceived discrimination were associated with select health behaviors among men and women. Health behaviors offer a potential mechanism through which perceived discrimination affects health in AA. PMID:26417003

  10. A study of the remote neighborhood office center concept

    NASA Technical Reports Server (NTRS)

    1976-01-01

    The substitution of communications for commuting to work is examined from several aspects. Attention is focused on the possibility of certain groups of white collar workers conducting their business affairs through a network of Remote Neighborhood Office Centers (RNOC's) located near their homes. Typically, employees would communicate with their headquarters organizations by means of voice and digital circuits. Although current technology is readily able to support such an RNOC network, the main problems confronting would-be implementers center around the need for demonstrating that a sufficient number of business operations can be carried out in such a decentralized configuration as efficiently as they are under more conventional circumstances. The description of a pilot program is presented which is intended to identify pacing issues that must be settled before firm conclusions can be reached on whether the concept is operationally viable.

    The results from two long observations with the Einstein Observatory Imaging Proportional Counter (IPC) of an approximately 1 x 1 deg field centered near the galactic nucleus are presented. The X-ray images reveal a complex of weak sources within 20 arcmin of the galactic nucleus (Sgr A West) together with a region of apparently diffuse emission about 25 x 15 arcmin in extent. Three of the sources are tentatively identified: two with nearby galactic objects, and a third positionally coincident with Sgr A West itself (within the arcmin-accuracy available with the IPC). The nature of this source and the implications of both the high source density and presence of diffuse emission in the galactic center region are discussed.

    The Center for Integrated Nanotechnologies (CINT), located at Sandia National Laboratories in Albuquerque, New Mexico, is one of five new Department of Energy Nanoscale Science Research Centers (NSRC). The CINT vision is to become a world leader in nanoscale science by developing the scientific principles that govern the design, performance, and integration of nanoscale materials, with emphasis on exploring the path from scientific discovery to the integration of nanostructures into the micro and macro worlds. The CINT design team faced the challenge of creating a state-of-the art research facility that is functional, flexible, and reflects the local history and environment. Drawing inspiration from Pre-Columbian Chacoan culture, the resulting design integrates scientific spaces with "communal" spaces to encourage the cross-discipline interaction that is essential to scientific research, particularly in the area of nanotechnology. Careful attention to design also produced a facility that conserves resources in the demanding Southwestern climate.

    Background and Purpose The majority of genome-wide association studies (GWAS) of stroke have focused on European-ancestry populations; however, none has been conducted in African-Americans despite the disproportionately high burden of stroke in this population. The Consortium of Minority Population genome-wide Association Studies of Stroke (COMPASS) was established to identify stroke susceptibility loci in minority populations. Methods Using METAL, we conducted meta-analyses of GWAS in 14,746 African-Americans (1,365 ischemic and 1,592 total stroke cases) from COMPASS, and tested SNPs with P<10−6 for validation in METASTROKE, a consortium of ischemic stroke genetic studies in European-ancestry populations. We also evaluated stroke loci previously identified in European-ancestry populations. Results The 15q21.3 locus linked with lipid levels and hypertension was associated with total stroke (rs4471613, P=3.9×10−8) in African-Americans. Nominal associations (P<10−6) for total or ischemic stroke were observed for 18 variants in or near genes implicated in cell cycle/ mRNA pre-splicing (PTPRG, CDC5L), platelet function (HPS4), blood-brain barrier permeability (CLDN17), immune response (ELTD1, WDFY4, IL1F10-IL1RN), and histone modification (HDAC9). Two of these loci achieved nominal significance in METASTROKE: 5q35.2 (P=0.03), and 1p31.1 (P=0.018). Four of 7 previously reported ischemic stroke loci (PITX2, HDAC9, CDKN2A/CDKN2B and ZFHX3) were nominally associated (P<0.05) with stroke in COMPASS. Conclusions We identified a novel SNP associated with total stroke in African-Americans and found that ischemic stroke loci identified in European-ancestry populations may also be relevant for African-Americans. Our findings support investigation of diverse populations to identify and characterize genetic risk factors, and the importance of shared genetic risk across populations. PMID:26089329

    Ticks and tick-borne diseases are among the main causes of economic loss in the South African cattle industry through high morbidity and mortality rates. Concerns of the general public regarding chemical residues may tarnish their perceptions of food safety and environmental health when the husbandry of cattle includes frequent use of acaricides to manage ticks. The primary objective of this study was to identify single nucleotide polymorphism (SNP) markers associated with host resistance to ticks in South African Nguni cattle. Tick count data were collected monthly from 586 Nguni cattle reared in four herds under natural grazing conditions over a period of two years. The counts were recorded for six species of ticks attached in eight anatomical locations on the animals and were summed by species and anatomical location. This gave rise to 63 measured phenotypes or traits, with results for 12 of these traits being reported here. Tick count (x) data were transformed using log10(x+1) and the resulting values were examined for normality. DNA was extracted from hair and blood samples and was genotyped using the Illumina BovineSNP50 assay. After quality control (call rate >90%, minor allele frequency >0.02), 40,436 SNPs were retained for analysis. Genetic parameters were estimated and association analysis for tick resistance was carried out using two approaches: a genome-wide association (GWA) analysis using the GenABEL package and a regional heritability mapping (RHM) analysis. The Bonferroni genome-wide (P<0.05) corrected significance threshold was 1.24×10(-6), with 2.47×10(-5) as the suggestive significance threshold (P<0.10) (i.e., one false positive per genome scan) in the GWA analysis. Likelihood ratio test (LRT) thresholds for genome-wide and suggestive significance were 13.5 and 9.15 for the RHM analysis. Six ixodid tick species were identified, with Amblyomma hebraeum (the vector for Heartwater disease) being the dominant species. Heritability estimates (h(2

    2008-01-01

    Problem: Four consumer health information centers in Richmond, Virginia, provide one-on-one assistance in accessing health information. Because they may not be fully utilized at present, an exploratory marketing study of factors affecting usage of the centers was conducted. Method: Observers counted center passers-by and tracked their paths. Also, brief intercept interviews were conducted with people who had just used a center, people nearby who could have used one but did not, and people on the street. Finally, in-depth individual interviews were conducted with key informants. Results: There was a high degree of satisfaction with the centers among users. Nonusers universally endorsed the center concept. However, most passers-by did not even glance at the centers, and intercept interviewees suggested better signage and promoting the resource centers through various media channels. Key informants added suggestions about interpersonal strategies (e.g., physician referrals) for center usage promotion but cautioned that a large increase in traffic could not be accommodated without increasing staff size or shifting from a model of individualized service. Conclusions: Triangulating findings from multiple data collection methods can provide useful guidance for efforts to promote center utilization. At minimum, steps should be taken to make the largest centers more noticeable. Because center utilization is not only associated with consumer satisfaction with hospitals, but may also foster health literacy, both hospital-based and community-based usage promotion strategies may be warranted. All such promotional strategies should be audience-tested before they are adopted. PMID:18219380

    The American Cancer Society provides estimates on the number of new cancer cases and deaths, and compiles health statistics on African Americans in a biennial publication, Cancer Facts and Figures for African Americans. The compiled statistics include cancer incidence, mortality, survival, and lifestyle behaviors using the most recent data on incidence and survival from the National Cancer Institute's (NCI) Surveillance, Epidemiology, and End Results (SEER) program, mortality data from the National Center for Health Statistics (NCHS), and behavioral information from the Behavior Risk Factor Surveillance System (BRFSS), Youth Risk Behavior Surveillance System (YRBSS), and National Health Interview Survey (NHIS). It is estimated that 132,700 new cases of cancer and 63,100 deaths will occur among African Americans in the year 2003. Although African Americans have experienced higher incidence and mortality rates of cancer than whites for many years, incidence rates have declined by 2.7 percent per year in African-American males since 1992, while stabilizing in African-American females. During the same period, death rates declined by 2.1 percent and 0.4 percent per year among African-American males and females, respectively. The decrease in both incidence and death rates from cancer among African-American males was the largest of any racial or ethnic group. Nonetheless, African Americans still carry the highest cancer burden among US racial and ethnic groups. Most cancers detectable by screening are diagnosed at a later stage and survival rates are lower within each stage of disease in African Americans than in whites. The extent to which these disparities reflect unequal access to health care versus other factors is an active area of research.

    This study reports the initial results of a baseline cross-sectional evaluation of the health and nutritional status of 58 old-old African Americans, 74 years of age and older, residing in low income housing complexes in metropolitan Oklahoma City. Although the population had a high overall functional status, cognitive status, and mood, there were a number of nutritional parameters suggestive of nutritional risk. In particular, 20% of subjects had relatively low serum albumin levels, 14% had serum cholesterol levels below 160 mg/dl, and a subset of the population reported low intake during 24 hour dietary recall. The National Center and Caucus on Black Aged report that 60% of African American elders live at or below the poverty level. These study findings suggest that the present cohort of African American elders may be at nutritional risk.
