Research Synthesis, HIV Prevention Response, and Public Health: CDC's HIV/AIDS Prevention Research Synthesis Project.

OBJECTIVE: Research synthesis, through qualitative or quantitative systematic reviews, allows for integrating results of primary research to improve public health. We examined more than 2 decades of work in HIV prevention by the Centers for Disease Control and Prevention's (CDC's) HIV/AIDS Prevention Research Synthesis (PRS) Project. We describe the context and contributions of research synthesis, including systematic reviews and meta-analyses, through the experience of the PRS Project. METHODS: We reviewed PRS Project publications and products and summarized PRS contributions from 1996 to July 2020 in 4 areas: synthesis of interventions and epidemiologic studies, synthesis methods, prevention programs, and prevention policy. RESULTS: PRS Project publications summarized risk behaviors and effects of prevention interventions (eg, changing one's perception of risk, teaching condom negotiation skills) across populations at risk for HIV infection and intervention approaches (eg, one-on-one or group meetings) as the HIV/AIDS epidemic and science evolved. We used the PRS Project cumulative database and intervention efficacy reviews to contribute to prevention programs and policies through identification of evidence-based interventions and development of program guidance. Subject matter experts and scientific evidence informed PRS Project products and contributions, which were implemented through strategic programmatic partnerships. CONCLUSIONS: The contributions of the PRS Project to HIV prevention and public health efforts in the United States can be credited to CDC's long-standing support of the project and its context within a federal prevention agency, where HIV programs and policies were developed and implemented. The effect of the PRS Project was likely facilitated by opportunities to directly influence program and policy because of connections with other research translation activities and program and policy decision making within CDC.

Comparison of rural and urban French GPs' activity: a cross-sectional study.

INTRODUCTION: In various countries, a shortage of general practitioners (GPs) and worrying health statistics on risk factors, morbidity and mortality have been observed in rural areas. However, few comparative data are available on GP activities according to their location. The aim of this study was to analyse French GP activities according to their rural or urban practice location. METHODS: This study was ancillary to the Eléments de la COnsultation en médecine GENérale (ECOGEN) study, which was a cross-sectional, multicentre, national study conducted in 128 French general practices in 2012. Data were collected by 54 interns in training during a period of 20 working days from December 2011 to April 2012. GP practice location was classified as rural area, urban cluster or urban area. The International Classification of Primary Care (ICPC-2) was used to classify reasons for encounter, health problem assessments, and processes of care. Univariate analyses were performed for all dependent variables, then multivariable analyses for key variables, using hierarchical mixed-effect models. RESULTS: The database included 20 613 consultations. The mean yearly number of consultations per GP was higher in rural areas (p<0.0001), with a shorter consultation length (p<0.0001). No difference was found for GP sex (p=0.41), age (p=0.87), type of fees agreement (p=0.43), and type of practice (p=0.19) according to their practice location. Urban patients were younger, and there was a lower percentage of patients over 75 years (p<0.001). GPs more frequently consulted at patients' homes in rural areas (p<0.0001). The mean number of chronic conditions managed was higher in rural areas and urban clusters than in urban areas (p<0001). Hypertension (p<0.0001), type 2 diabetes (p=0.003), and acute bronchitis/bronchiolitis (p=0.01) were more frequently managed in rural areas than in urban clusters and areas. Health maintenance/prevention (p<0.0001) and no disease situations (p<0.0001) were less frequent in rural areas. Drug prescription was more frequent in rural areas than in urban clusters and areas (p<0.0001). Multivariable analysis confirmed the influence of a GP's rural practice location on the consultation length (p<0.0001), the number of chronic conditions per consultation (p<0.0001) and the number of health maintenance/prevention situations (p<0.0001), and a trend towards a higher yearly number of consultations per GP (p=0.09). CONCLUSION: French rural GPs tend to have a higher workload than urban GPs. Rural patients have more chronic conditions to be managed but are offered fewer preventive services during consultations. It is necessary to increase the GP workforce and develop cooperation with allied health professionals in rural areas.

Capacity Building for Primary Stroke Prevention Teams in Children Living With Sickle Cell Anemia in Africa.

BACKGROUND: Nigeria has the highest proportion of children with sickle cell anemia (SCA) globally; an estimated 150,000 infants with SCA are born annually. Primary stroke prevention in children with SCA must include Nigeria. We describe capacity-building strategies in conjunction with two National Institutes of Health-funded primary stroke prevention trials (a feasibility trial and phase III randomized controlled trial) with initial hydroxyurea treatment for children with SCA and abnormal transcranial Doppler (TCD) velocities in Nigeria. We anticipated challenges to conducting clinical trials in a low-resource setting with a local team that had not previously been involved in clinical research and sought a sustainable strategy for primary stroke prevention. METHODS: This is a descriptive, prospective study of challenges, solutions, and research teams in two trials that enrolled a total of 679 children with SCA. RESULTS: As part of the capacity-building component of the trials, over eight years, 23 research personnel (physicians, nurses, research coordinators, a statistician, and a pharmacist) completed a one-month research governance and ethics training program at Vanderbilt University Medical Center, USA. A lead research coordinator for each site completed the Society of Clinical Research Professionals certification. TCD machines were donated; radiologists and nonradiologists were trained and certified to perform TCD. A scalable E-prescription was implemented to track hydroxyurea treatment. We worked with regional government officials to support ongoing TCD-based screening and funding for hydroxyurea for children with SCA at a high risk of stroke. CONCLUSIONS: Our trials and capacity building demonstrate a sustainable strategy to initiate and maintain pediatric SCA primary stroke prevention programs in Africa.

A review and agenda for integrated disease models including social and behavioural factors.

Social and behavioural factors are critical to the emergence, spread and containment of human disease, and are key determinants of the course, duration and outcomes of disease outbreaks. Recent epidemics of Ebola in West Africa and coronavirus disease 2019 (COVID-19) globally have reinforced the importance of developing infectious disease models that better integrate social and behavioural dynamics and theories. Meanwhile, the growth in capacity, coordination and prioritization of social science research and of risk communication and community engagement (RCCE) practice within the current pandemic response provides an opportunity for collaboration among epidemiological modellers, social scientists and RCCE practitioners towards a mutually beneficial research and practice agenda. Here, we provide a review of the current modelling methodologies and describe the challenges and opportunities for integrating them with social science research and RCCE practice. Finally, we set out an agenda for advancing transdisciplinary collaboration for integrated disease modelling and for more robust policy and practice for reducing disease transmission.

Epidemiology, Ecology and Prevention of Plague in the West Nile Region of Uganda: The Value of Long-Term Field Studies.

Plague, a fleaborne rodent-associated zoonosis, is a neglected disease with most recent cases reported from east and central Africa and Madagascar. Because of its low incidence and sporadic occurrence, most of our knowledge of plague ecology, prevention, and control derives from investigations conducted in response to human cases. Long-term studies (which are uncommon) are required to generate data to support plague surveillance, prevention, and control recommendations. Here we describe a 15-year, multidisciplinary commitment to plague in the West Nile region of Uganda that led to significant advances in our understanding of where and when persons are at risk for plague infection and how to reduce morbidity and mortality. These findings provide data-driven support for several existing recommendations on plague surveillance and prevention and may be generalizable to other plague foci.

GLOBAL ENDOCRINOLOGY: Global perspectives in endocrinology: coverage of iodized salt programs and iodine status in 2020.

Iodine deficiency has multiple adverse effects on growth and development. Diets in many countries cannot provide adequate iodine without iodine fortification of salt. In 2020, 124 countries have legislation for mandatory salt iodization and 21 have legislation allowing voluntary iodization. As a result, 88% of the global population uses iodized salt. For population surveys, the urinary iodine concentration (UIC) should be measured and expressed as the median, in µg/L. The quality of available survey data is high: UIC surveys have been done in 152 out of 194 countries in the past 15 years; in 132 countries, the studies were nationally representative. The number of countries with adequate iodine intake has nearly doubled from 67 in 2003 to 118 in 2020. However, 21 countries remain deficient, while 13 countries have excessive intakes, either due to excess groundwater iodine, or over-iodized salt. Iodine programs are reaching the poorest of the poor: of the 15 poorest countries in the world, 10 are iodine sufficient and only 3 (Burundi, Mozambique and Madagascar) remain mild-to-moderately deficient. Nigeria and India have unstable food systems and millions of malnourished children, but both are iodine-sufficient and population coverage with iodized salt is a remarkable 93% in both. Once entrenched, iodine programs are often surprisingly durable even during national crises, for example, war-torn Afghanistan and Yemen are iodine-sufficient. However, the equity of iodized salt programs within countries remains an important issue. In summary, continued support of iodine programs is needed to sustain these remarkable global achievements, and to reach the remaining iodine-deficient countries.

Four-Year Behavioral, Health-Related Quality of Life, and BMI Outcomes from a Cluster Randomized Whole of Systems Trial of Prevention Strategies for Childhood Obesity.

OBJECTIVE: This study aimed to test the effectiveness of the Whole of Systems Trial of Prevention Strategies for Childhood Obesity (WHO STOPS Childhood Obesity) for behavioral, health-related quality of life (HRQoL), and BMI outcomes. METHODS: This was a cluster randomized trial of 10 communities randomly allocated (1:1) to start intervention in 2015 (step 1) or in 2019 (after 4 years) in South West Victoria, Australia. Data were collected from participating primary schools in April to June of 2015 (73% school participation rate), 2017 (69%), and 2019 (63%). Student participation rates were 80% in 2015 (1,792/2,516 invited), 81% in 2017 (2,411/2,963), and 79% in 2019 (2,177/2,720). Repeat cross-sectional analyses of measured height and weight (grades two, four, and six [aged approximately 7 to 12 years]), self-reported behavior, and HRQoL (grades four and six) were conducted. RESULTS: There was an intervention by time interaction in BMI z scores (P = 0.031) and obesity/overweight prevalence (P = 0.006). BMI z score and overweight/obesity prevalence decreased between 2015 and 2017 and increased between 2017 and 2019 in intervention communities. The intervention significantly reduced takeaway food consumption (P = 0.034) and improved physical (P = 0.019), psychosocial (P = 0.026), and global (P = 0.012) HRQoL. Water consumption increased among girls (P = 0.033) in the intervention communities, as did energy-dense, nutrient-poor snack consumption among boys (P = 0.006). CONCLUSIONS: WHO STOPS had a positive impact on takeaway food intake and HRQoL.

National Heart Foundation of Australia: position statement on coronary artery calcium scoring for the primary prevention of cardiovascular disease in Australia.

INTRODUCTION: This position statement considers the evolving evidence on the use of coronary artery calcium scoring (CAC) for defining cardiovascular risk in the context of Australian practice and provides advice to health professionals regarding the use of CAC scoring in primary prevention of cardiovascular disease in Australia. Main recommendations: CAC scoring could be considered for selected people with moderate absolute cardiovascular risk, as assessed by the National Vascular Disease Prevention Alliance (NVDPA) absolute cardiovascular risk algorithm, and for whom the findings are likely to influence the intensity of risk management. (GRADE evidence certainty: Low. GRADE recommendation strength: Conditional.) CAC scoring could be considered for selected people with low absolute cardiovascular risk, as assessed by the NVDPA absolute cardiovascular risk algorithm, and who have additional risk-enhancing factors that may result in the underestimation of risk. (GRADE evidence certainty: Low. GRADE recommendation strength: Conditional.) If CAC scoring is undertaken, a CAC score of 0 AU could reclassify a person to a low absolute cardiovascular risk status, with subsequent management to be informed by patient-clinician discussion and follow contemporary recommendations for low absolute cardiovascular risk. (GRADE evidence certainty: Very low. GRADE recommendation strength: Conditional.) If CAC scoring is undertaken, a CAC score > 99 AU or ≥ 75th percentile for age and sex could reclassify a person to a high absolute cardiovascular risk status, with subsequent management to be informed by patient-clinician discussion and follow contemporary recommendations for high absolute cardiovascular risk. (GRADE evidence certainty: Very low. GRADE recommendation strength: Conditional.) CHANGES IN MANAGEMENT AS A RESULT OF THIS STATEMENT: CAC scoring can have a role in reclassification of absolute cardiovascular risk for selected patients in Australia, in conjunction with traditional absolute risk assessment and as part of a shared decision-making approach that considers the preferences and values of individual patients.

A critical review of national diabetes prevention and control programs in 12 countries in Middle East.

BACKGROUND: Diabetes mellitus has been known as one of the most significant systemic diseases with severe consequences and challenges to human health. AIM: The primary aim of the current paper was to review the diabetes prevention programs in the Middle East countries, and secondary compare their goals and success rate and conclude possible upcoming strategies. METHODS: All reports and documents regarding to diabetes prevention and control programs in the region were collected by searching Web of Science, PubMed, MEDLINE, Google Scholar, Scopus and EMBASE for articles up to 2020. The health policy triangle framework was used to analyze diabetes policies and programs. In the Middle East, a shift from rural to urban life, socioeconomic development, sedentary lifestyles, and high fat and sugary foods consumption led to increasing in obesity and diabetes rate, which have become a real challenge. RESULTS: To decrease the burden of diabetes, preventive strategies with proper local socio-cultural context are needed. Evaluation of current policies and identifying stakeholders' views can help to improve the current strategies for the prevalence of diabetes and its complications. CONCLUSIONS: It can provide local and global insight to evidence-informed decision-making for future policy reforms to enhance effectiveness of the program.

Targeting of the diabetes prevention program leads to substantial benefits when capacity is constrained.

OBJECTIVE: Approximately 84 million people in the USA have pre-diabetes, but only a fraction of them receive proven effective therapies to prevent type 2 diabetes. We estimated the value of prioritizing individuals at highest risk of progression to diabetes for treatment, compared to non-targeted treatment of individuals meeting inclusion criteria for the Diabetes Prevention Program (DPP). METHODS: Using microsimulation to project outcomes in the DPP trial population, we compared two interventions to usual care: (1) lifestyle modification and (2) metformin administration. For each intervention, we compared targeted and non-targeted strategies, assuming either limited or unlimited program capacity. We modeled the individualized risk of developing diabetes and projected diabetic outcomes to yield lifetime costs and quality-adjusted life expectancy, from which we estimated net monetary benefits (NMB) for both lifestyle and metformin versus usual care. RESULTS: Compared to usual care, lifestyle modification conferred positive benefits and reduced lifetime costs for all eligible individuals. Metformin's NMB was negative for the lowest population risk quintile. By avoiding use when costs outweighed benefits, targeted administration of metformin conferred a benefit of $500 per person. If only 20% of the population could receive treatment, when prioritizing individuals based on diabetes risk, rather than treating a 20% random sample, the difference in NMB ranged from $14,000 to $20,000 per person. CONCLUSIONS: Targeting active diabetes prevention to patients at highest risk could improve health outcomes and reduce costs compared to providing the same intervention to a similar number of patients with pre-diabetes without targeted selection.

Life Course Health Development in Pediatric Practice.

The development of health is a cumulative, dynamic, and lifelong process responding to a variety of biological and behavioral influences, of which those in childhood are especially influential and, indeed, formative. Reflecting the balance of positive and adverse experiences during childhood, initial trajectories for future health and development emerge. Preventive pediatric care can anticipate and respond to those experiences and the personal and social circumstances in which they occur. These actions can promote better health and prevent chronic illness during adulthood. Building on the life course health development framework, ways to positively affect patterns of individual and population health practice are identified. Maximizing the opportunity to influence children's health over their lifetime will require purposeful partnerships with other entities with which children and their families interact as well as improvements in pediatric care processes. The latter includes expanding the databases that drive service (such as registries, care plans, and referrals) and adopting proactive, strengths-based, patient and family-centered, comprehensive, multidisciplinary models of care.

Epidemiology of imported infectious diseases, China, 2014-18.

BACKGROUND: The frequent movement of population between countries brings an increasing number of travel-related infections. This study aims to define the spectrum and dynamics of imported infections observed from international travel in the Chinese mainland. METHODS: Sick travellers were screened by inbound sentinel surveillance and post-travel clinic visits from 2014 to 18. The infections were classified as respiratory, gastrointestinal, vector-borne, blood/sexually transmitted and mucocutaneous. The analysed variables included the place of origin of the travellers (Chinese or foreign) and the time when travel-related infection was present (at the time of return, during travel and post-travel visits to the clinic). RESULTS: In total, 58 677 cases were identified amongst 1 409 265 253 travellers, with an incidence of 41.64/million, comprising during-travel incidence of 27.44/million and a post-travel incidence of 14.20/million. Respiratory infections constituted the highest proportion of illnesses during travel (81.19%, 31 393 of 38 667), which mainly came from Asian countries and tourists; with influenza virus and rhinovirus infections being mainly diagnosed. Vector-borne diseases constituted the highest proportion of post-travel illnesses (98.14%, 19 638 of 20 010), which were mainly diagnosed from African countries and labourers; with malaria and dengue fever being mainly diagnosed. The differential infection spectrum varied in terms of the traveller's demography, travel destination and travel purpose. As such, a higher proportion of foreign travellers had blood/sexually transmitted diseases (89.85%, 2832 of 3152), while Chinese citizens had a higher prevalence of vector-borne diseases (85.98%, 19 247 of 22 387) and gastrointestinal diseases (79.36%, 1115 of 1405). The highest incidence rate was observed amongst travellers arriving from Africa, while the lowest was observed amongst travellers arriving from Europe. CONCLUSIONS: The findings might help in preparing recommendations for travellers and also aid in primary care or other clinics that prepare travellers before trips abroad. The findings will also help to identify locations and the associated types of infections that might require attention.

Prevention of SARS-COV-2 coronavirus spread at the Auschwitz-Birkenau State Museum in Poland. The most visited Memorial site in the world during the COVID-19 pandemic.

INTRODUCTION: At the Auschwitz-Birkenau State Museum (A-BSM) actions have been undertaken to effectively protect employees and minimise risk of SARS-CoV-2 coronavirus spreading from the beginning of the COVID-19 epidemic. AIM OF THE ARTICLE: The aim was to present the actions, instructions and procedures introduced at the A-BSM to provide information how to deal with pandemic caused by the SARS-CoV-2 coronavirus in institutions taking care of cultural heritage before and after closure of the Museum for visitors and after reopening. MATERIALS AND METHODS: The described activities were developed at the Museum by a specially established Expert Team. RESULTS: Groups of employees and places in which they were most exposed to contact with visitors and, as a consequence, at the highest risk of getting infected, were characterised. The employees were provided with personal protective equipment, and at the Museum site, devices essential for maintaining the microbiological cleanliness of the rooms, were placed. In the next stage, instructions and procedures for particular groups of employees were prepared. Visitors were educated about the need of taking precautions and were allowed to disinfect in several places at the Memorial Site. Steps to reduce attendance at this time has also been taken. Procedures for employees of the A-BSM were developed in such way that they can also be used after reopening of the Museum for visitors. CONCLUSIONS: The actions which ensured the microbiological safety of the A-BSM employees, brought satisfying results. In more than 21 days after closing of the Museum for visitors, no cases of SARS-CoV-2 infection or COVID-19 were found among employees, despite a very high threat.

Virtual CROI 2020: Highlights of Epidemiology, Public Health, and Prevention Research.

At the 2020 Conference on Retroviruses and Opportunistic Infections, held virtually as a result of the emerging COVID-19 pandemic, trends in the HIV epidemic were highlighted, with decreasing HIV incidence reported across several countries, although key regions remain heavily impacted, including the US South. Adolescent girls and young women, men who have sex with men (MSM), transgender persons, and people who inject drugs continue to experience a high burden of new infections. Sexually transmitted infections during pregnancy can lead to a number of adverse outcomes in infants; novel strategies to detect and treat these infections are needed. Innovative HIV testing strategies, including self-testing and assisted partner services, are expanding the reach of testing; however, linkage to care can be improved. Novel preexposure prophylaxis (PrEP) delivery strategies are increasing uptake of PrEP in different groups, although adherence and persistence remain a challenge. Use of on-demand PrEP is increasing among MSM in the US. Strategies are needed to address barriers to PrEP uptake and persistence among cis- and transgender women. Several novel regimens for postexposure prophylaxis show promise.

Lipoprotein(a) and Family History Predict Cardiovascular Disease Risk.

BACKGROUND: Elevated lipoprotein(a) (Lp[a]) and family history (FHx) of coronary heart disease (CHD) are individually associated with cardiovascular risk, and Lp(a) is commonly measured in those with FHx. OBJECTIVES: The aim of this study was to determine independent and joint associations of Lp(a) and FHx with atherosclerotic cardiovascular disease (ASCVD) and CHD among asymptomatic subjects. METHODS: Plasma Lp(a) was measured and FHx was ascertained in 2 cohorts. Elevated Lp(a) was defined as the highest race-specific quintile. Independent and joint associations of Lp(a) and FHx with cardiovascular risk were determined using Cox regression models adjusted for cardiovascular risk factors. RESULTS: Among 12,149 ARIC (Atherosclerosis Risk In Communities) participants (54 years, 56% women, 23% black, 44% with FHx), 3,114 ASCVD events were observed during 21 years of follow-up. FHx and elevated Lp(a) were independently associated with ASCVD (hazard ratio [HR]: 1.17; 95% confidence interval [CI]: 1.09 to 1.26, and HR: 1.25; 95% CI: 1.12 to 1.40, respectively), and no Lp(a)-by-FHx interaction was noted (p = 0.75). Compared with subjects without FHx and nonelevated Lp(a), those with either elevated Lp(a) or FHx were at a higher ASCVD risk, while those with both had the highest risk (HR: 1.43; 95% CI: 1.27 to 1.62). Similar findings were observed for CHD risk in ARIC, in analyses stratified by premature FHx, and in an independent cohort, the DHS (Dallas Heart Study). Presence of both elevated Lp(a) and FHx resulted in greater improvement in ASCVD and CHD risk reclassification and discrimination indexes than either marker alone. CONCLUSIONS: Elevated plasma Lp(a) and FHx have independent and additive joint associations with cardiovascular risk and may be useful concurrently for guiding primary prevention therapy decisions.

Examining the implementation of the Icelandic model for primary prevention of substance use in a rural Canadian community: a study protocol.

BACKGROUND: The Icelandic Prevention Model (IPM) is a collaborative upstream model that was designed to influence risk and protective factors related to substance use within the community, school, peer and family contexts. By engaging whole communities, the IPM has been found to be effective in reducing youth substance use behaviours across Iceland. As an extension to the IPM's participatory approach, this research will examine how youth involvement can enhance outcomes. In addition, this research will evaluate whether the IPM approach is beneficial for mental health promotion and general youth wellbeing. METHODS: The present research protocol applies the bioecological model within a participatory mixed-method case study design to examine the implementation of the IPM in a rural community in Canada. This study was designed to identify whether the Icelandic substance use prevention model is effective in reducing substance use and promoting mental health and development for Canadian youth. It will also explore how to engage youth within the approach and how this adaptation influences implementation and outcomes. DISCUSSION: The findings from this study will contribute to our understanding of upstream prevention of youth substance use and will be used to support scaling of the IPM across Canada.

Individualized approach to primary prevention of substance use disorder: age-related risks.

BACKGROUND: The misuse of legal and illegal substances has led to an increase in substance use disorder (SUD) in the United States. Although primary prevention strategies have been successfully used to target chronic physical diseases, these strategies have been less effective with SUD, given misconceptions of SUD, shortages in behavioral health professionals, and the population-based focus on specific substances. A developmental approach to the identification and primary prevention of SUD that does not fully rely upon behavioral health workers is needed. The purpose of this paper was to examine age related risk factors for developing SUD and present a novel individualized approach to SUD prevention. METHODS: A literature search was conducted to identify risk factors for SUD among children, young adults, adults, and older adults. We searched CINAHL, PsycINFO, and PubMed between the years 1989-2019, and extracted data, analyzing similarities and differences in risk factors across life stages. Broader categories emerged that were used to group the risk factors. RESULTS: More than 370 articles were found. Across all age groups, risk factors included adverse childhood experiences, trauma, chronic health diseases, environmental factors, family history, social determinants, and grief and loss. Despite the similarities, the contextual factors and life challenges associated with these risks varied according to the various life stages. We proposed an approach to primary prevention of SUD based on risk factors for developing the disease according to different age groups. This approach emphasizes screening, education, and empowerment (SEE), wherein individuals are screened for risk factors according to their age group, and screening results are used to customize interventions in the form of education and empowerment. Given that trained persons, including non-healthcare providers, close to the at-risk individual could conduct the screening and then educate and mentor the individual according to the risk level, the number of people who develop SUD could decrease. CONCLUSIONS: The risk factors for developing SUD vary across the various life stages, which suggests that individualized approaches that do not overtax behavioral healthcare workers are needed. Using SEE may foster early identification and individualized prevention of SUD.
