Immediate pressor response to oral salt and its assessment in the clinic: a time series clinical trial.

BACKGROUND: High blood pressure (BP) is associated with high-salt consumption especially in sub-Saharan Africa. Although the pressor effect of salt is viewed as a chronic effect, some studies suggest that a salty meal may increase BP immediately in some individuals, and that this effect may cause endothelial dysfunction. Therefore, the aim of our research was to study the immediate pressor response to oral salt (IPROS) and its determinants, with the expectation that a simple methodology may be devised to diagnose it in the clinic or in low-resource environments. METHODS: We conducted a time series trial at Livingstone Central Hospital. We present data in 127 normotensive participants who ingested 2 g of sodium chloride; their BP was monitored for 120 minutes in intervals of 10 minutes. Sociodemographic and clinical data were collected. Descriptive and inferential statistics were used for analyses of data. RESULTS: Median age was 30 years (interquartile range, 22-46 years) and 52% were female patients. An increase of ≥10 mmHg in mean arterial pressure (MAP), considered a clinically significant IPROS, was present in 62% of participants. Systolic BP 30 minutes after the salt load was a significant predictor of IPROS, avoiding the need to calculate MAP in the clinic setting. CONCLUSIONS: We confirm the presence of an IPROS in a high proportion (62%) of otherwise normotensive participants. The average time course for this response was 30 minutes and its duration was sustained for the 120-minutes period of study in most of the participants. Prediction of IPROS by ∆SBP (change in systolic blood pressure) at 30 minutes allows for easy assessment of possible responder status in the clinic. Our data indicate that the IPROS to oral salt-loads in the range currently consumed by the Western world and African populations in single meals may increase the 24-hour BP load, which is a risk factor for hypertension and target organ damage. The relevance of our findings indicates the need to include dietary sodium assessment in the diagnosis, prevention, and management of high BP.

Expanding Global Health Engagement through Fogarty Fellowship Programs.

Training the next generation of global health researchers is vital for sustainable research partnerships and global health equity. The Fogarty International Center (National Institutes of Health) supports postdoctoral fellows and professional/graduate students in long-term, hands-on mentored research in low- and middle-income countries (LMICs). We surveyed 627 alumni (58% from the United States, 42% from LMICs) from three sequential Fogarty-sponsored global health research training programs (response rate: N = 257, 41%). Publications in the Index Medicus were used to ascertain scholarly output. Most alumni (63%) reported remaining engaged in LMICs and/or worked in academic/research careers (70%). Since completing their Fogarty fellowship, 144 alumni (56%) had received 438 new grants as principal investigator (PI), co-/multi-PI, or site PI. The 257 responding alumni had 5,318 publications during and since their Fogarty fellowships; 2,083 (39%) listed the Fogarty trainee as the first or senior author. These global health training programs highlight the value of LMIC research experience in nurturing the global health research workforce.

HIV Research Training Partnership of the University of Zambia and Vanderbilt University: Features and Early Outcomes.

Background: Despite the burden of HIV being highest in sub-Saharan Africa (SSA), research expertise and capacity to address scientific questions regarding complications of HIV and ART, especially chronic non-communicable conditions, is limited in the region. The comorbidities prevalent in persons with HIV are mediated through diverse mechanisms, many of which can be context or region-specific and are yet to be elucidated. The phenotype, risk factors, and effective interventions for these conditions may differ between populations and settings, and therefore there is an urgent need for research to help understand these processes and how to best address them in SSA. Here, we report the research capacity building activities in SSA conducted by the University of Zambia (UNZA)-Vanderbilt Training Partnership for HIV-Nutrition-Metabolic Research (UVP), drawing lessons and challenges for a wide global health audience. Methods: We reviewed program data and conducted interviews with program leaders and participants to understand and document the progress and outcomes of the partnership. We report the program's early achievements, highlighting drivers and challenges. Results: Between 2015 and 2019, UVP made substantial progress on its goals of training new UNZA PhD scientists to investigate complex nutritional and metabolic factors related to long-term HIV complications and comorbidities. The program has supported 11 UNZA PhD students with dual UNZA-Vanderbilt mentorship; three have graduated, and other candidates are progressing in their PhD studies. The project also supported institutional capacity through UNZA faculty participation in Vanderbilt grant writing workshops, with strong success in obtaining grants among those who participated. UVP also supported development of greater structure to UNZA's PhD program and a mentorship curriculum, both now adopted by UNZA. The major drivers for success included UVP's alignment of goals between UNZA and Vanderbilt, and local institutional ownership. The longstanding history of collaborations between the two institutions contributed substantially to alignment and mutual support of UVP's goals. Several challenges were noted, including limits on direct research funding for students and a relatively small pool of funded investigators at UNZA. Conclusions: Despite some challenges, UVP has achieved positive outcomes over its first four years. Longstanding partnerships and local institutional ownership were the main drivers. We expect the challenges to mitigated as the project continues and produces more UNZA researchers and teams and more funded projects, collectively building the local research community. With continued resources and clear focus, we expect that UNZA's investigators and partners will attract research funding and generate high-impact research outputs across a broad range of studies in HIV as well as newer threats from non-communicable conditions experienced by long-term survivors of HIV and by the general population.

Mentoring the Mentors: Implementation and Evaluation of Four Fogarty-Sponsored Mentoring Training Workshops in Low-and Middle-Income Countries.

A growing body of evidence highlights the importance of competent mentoring in academic research. We describe the development, implementation, and evaluation of four regional 2-day intensive workshops to train mid- and senior-level investigators conducting public health, clinical, and basic science research across multiple academic institutions in low- and middle-income countries (LMICs) on tools and techniques of effective mentoring. Sponsored by the Fogarty International Center, workshops included didactic presentations, interactive discussions, and small-group problem-based learning and were conducted in Lima, Peru; Mombasa, Kenya; Bangalore, India; and Johannesburg, South Africa, from 2013 to 2016. Mid- or senior-level faculty from multiple academic institutions within each region applied and were selected. Thirty faculty from 12 South America-based institutions, 29 faculty from eight East Africa-based institutions, 37 faculty from 14 South Asia-based institutions, and 36 faculty from 13 Africa-based institutions participated, with diverse representation across disciplines, gender, and academic rank. Discussions and evaluations revealed important comparisons and contrasts in the practice of mentoring, and specific barriers and facilitators to mentoring within each cultural and regional context. Specific regional issues related to hierarchy, the post-colonial legacy, and diversity arose as challenges to mentoring in different parts of the world. Common barriers included a lack of a culture of mentoring, time constraints, lack of formal training, and a lack of recognition for mentoring. These workshops provided valuable training, were among the first of their kind, were well-attended, rated highly, and provided concepts and a structure for the development and strengthening of formal mentoring programs across LMIC institutions.

Strengthening Mentoring in Low- and Middle-Income Countries to Advance Global Health Research: An Overview.

Mentoring is a proven path to scientific progress, but it is not a common practice in low- and middle-income countries (LMICs). Existing mentoring approaches and guidelines are geared toward high-income country settings, without considering in detail the differences in resources, culture, and structure of research systems of LMICs. To address this gap, we conducted five Mentoring-the-Mentor workshops in Africa, South America, and Asia, which aimed at strengthening the capacity for evidence-based, LMIC-specific institutional mentoring programs globally. The outcomes of the workshops and two follow-up working meetings are presented in this special edition of the American Journal of Tropical Medicine and Hygiene. Seven articles offer recommendations on how to tailor mentoring to the context and culture of LMICs, and provide guidance on how to implement mentoring programs. This introductory article provides both a prelude and executive summary to the seven articles, describing the motivation, cultural context and relevant background, and presenting key findings, conclusions, and recommendations.

Twenty-five-Year Follow-up of Short-term Cancer Research Trainees at the University of Alabama at Birmingham: a Brief Report.

Long-term follow-up is needed to evaluate the impact of short-term cancer research programs on the career trajectories of medical and graduate students. Participation in these programs may be crucial in fostering the next generation of cancer research scientists. This report presents the career outcomes and research productivity of 77 medical and public health students with 25 years of tracking data following their participation in a summer cancer research training program at the University of Alabama at Birmingham (UAB) in 1990-1998. Of 64 summer trainees with contact information, complete survey responses were received from 55 (86.0%) individuals. Over half reported clinical care of cancer patients and 18.2% stated that they were engaged in cancer research. Literature searches confirmed that 23.4% (18/77) of trainees have published cancer research papers. Future studies should explore the optimal timing of short-term post-baccalaureate academic cancer training experiences to identify participant characteristics and institutional factors that influence career choices and determine research productivity.

The National Institutes of Health Fogarty International Center Global Health Scholars and Fellows Program: Collaborating Across Five Consortia to Strengthen Research Training.

As demand for global health research training continues to grow, many universities are striving to meet the needs of trainees in a manner complementary to research priorities of the institutions hosting trainees, while also increasing capacity for conducting research. We provide an overview of the first 4 years of the Global Health Program for Fellows and Scholars, a collaboration of 20 U.S. universities and institutions spread across 36 low- and middle-income countries funded through the National Institutes of Health Fogarty International Center. We highlight many aspects of our program development that may be of interest to other multinational consortia developing global health research training programs.

Impact of Global Health Research Training on Scholarly Productivity: The Fogarty International Clinical Research Scholars and Fellows Program.

In the Fogarty International Clinical Research Scholars and Fellows (FICRS-F) Program, 536 U.S. and international doctoral and postdoctoral health profession students and trainees completed 1-year research training at research centers in low- and middle-income countries. To evaluate the Program's impact, we analyzed data gathered prospectively during the Program, from PubMed, and from a representative survey of alumni. Of 100 randomly selected respondents, 94 returned the survey. Reflecting the sources of funding, human immunodeficiency virus/acquired immunodeficiency syndrome was the focus of 47% of the projects, but research in noncommunicable diseases (NCDs) and dual infection/NCD-related topics increased over time. Among the first 1,617 alumni publications, output was associated positively with being an international versus U.S. trainee, a postdoctoral Fellow versus predoctoral Scholar, and accumulation of more years post-training (all P < 0.001). Fellows were first author on a higher proportion of their articles than were Scholars (P < 0.001), and U.S. trainees were more often first author than international trainees (P = 0.04). Survey respondents had submitted 117 grant applications, and 79 (67.5%) had been funded. The FICRS-F Program yielded substantial research productivity in the early post-training years. Research outputs and impact will increase over time as alumni careers mature and they gain research independence and assume leadership positions.

Impact of Global Health Research Training on Career Trajectories: The Fogarty International Clinical Research Scholars and Fellows Program.

From 2004 to 2012, the Fogarty International Clinical Research Scholars/Fellows Program (FICRS-F) provided 1-year research training opportunities for U.S. and international doctoral "Scholars" and postdoctoral "Fellows" at low- and middle-income country (LMIC) centers. We collected data prospectively and then surveyed a representative sample of 100 alumni (94% response), assessing Program impacts on their careers and collaborations. Frequently, collaborations continued beyond the formal training period with U.S.- (63%) and site-based mentors (66%). U.S. Fellows reported the highest post-training focus on research (88 on a 100-point scale), and the highest Program impact on competitiveness for career or training positions and choices of post-training topics and institutions (95 points). Interest in global health research increased markedly during the training period, especially for LMIC trainees, and was sustained post-training. LMIC alumni reported a significantly higher focus on global health and research than did U.S. alumni. Alumni reported that their mentored research training had a substantial impact on their career trajectories.

Global health research in narrative: a qualitative look at the FICRS-F experience.

For American professional and graduate health sciences trainees, a mentored fellowship in a low- or middle-income country (LMIC) can be a transformative experience of personal growth and scientific discovery. We invited 86 American trainees in the Fogarty International Clinical Research Scholars and Fellows Program and Fulbright-Fogarty Fellowship 2011-2012 cohorts to contribute personal essays about formative experiences from their fellowships. Nine trainees contributed essays that were analyzed using an inductive approach. The most frequently addressed themes were the strong continuity of research and infrastructure at Fogarty fellowship sites, the time-limited nature of this international fellowship experience, and the ways in which this fellowship period was important for shaping future career planning. Trainees also addressed interaction with host communities vis-à-vis engagement in project implementation. These qualitative essays have contributed insights on how a 1-year mentored LMIC-based research training experience can influence professional development, complementing conventional evaluations. Full text of the essays is available at http://fogartyscholars.org/.

Recruiting post-doctoral fellows into global health research: selecting NIH Fogarty International Clinical Research Fellows.

From 2008 to 2012, the National Institutes of Health (NIH) Fogarty International Clinical Research Fellows Program (FICRF) provided 1-year mentored research training at low- and middle-income country sites for American and international post-doctoral health professionals. We examined the FICRF applicant pool, proposed research topics, selection process, and characteristics of enrollees to assess trends in global health research interest and factors associated with applicant competitiveness. The majority (58%) of 67 US and 57 international Fellows were women, and 83% of Fellows had medical degrees. Most applicants were in clinical fellowships (41%) or residencies (24%). More applicants proposing infectious disease projects were supported (59%) than applicants proposing non-communicable disease (NCD) projects (41%), although projects that combined both topic areas were most successful (69%). The numbers of applicants proposing research on NCDs and the numbers of these applicants awarded fellowships rose dramatically over time. Funding provided to the FICRF varied significantly among NIH Institutes and Centers and was strongly associated with the research topics awarded.

Training programs within global networks: lessons learned in the Fogarty International Clinical Research Scholars and Fellows Program.

The Fogarty International Clinical Research Scholars and Fellows Support Center at Vanderbilt describes administrative lessons learned from the management of 436 scholars (American students or host country junior trainees) and 122 post-doctoral fellows (Americans or host country nationals). Trainees spent 10-11 months working on mentored research projects at 61 well-vetted sites in 27 low- or middle-income host countries (LMICs) with strong US partners. Economies of scale, strong centralized information exchange, and effective standardized operations linking US institutions with LMIC field sites were achieved in a program that minimized administrative overhead. Advantages and drawbacks of this approach are presented and discussed. Training of a new generation of global research leaders is greatly facilitated by an overseas mentored research experience that is administratively streamlined to optimize the use of resources for training, research, and capacity building.

Nurturing the global workforce in clinical research: the National Institutes of Health Fogarty International Clinical Scholars and Fellows Program.

The Fogarty International Clinical Research Scholars and Fellows Program's goal is to foster the next generation of clinical investigators and to help build international health research partnerships between American and international investigators and institutions. Through June 2012, 61 sites in 27 countries have hosted 436 Scholars (American students or junior trainees from the host countries) and/or 122 Fellows (American and host country postdoctoral fellows) for year-long experiences in global health research. Initially, the program was oriented toward infectious diseases, but recently emphasis on chronic disease research has increased. At least 521 manuscripts have been published, many in high-impact journals. Projects have included clinical trials, observational studies, translational research, clinical-laboratory interface initiatives, and behavioral research. Strengths of the program include training opportunities for American and developing country scientists in well-established international clinical research settings, and mentorship from experienced global health experts.

The Intersociety Professional Nutrition Education Consortium and American Board of Physician Nutrition Specialists: what have we learned?

A significant obstacle to nutrition literacy among physicians is a paucity of physician nutrition specialists (PNSs) on medical school faculties who can effectively advocate for change in medical school and residency curricula, and who can serve as role models for incorporating nutrition into patient care. To address these issues, the Intersociety Professional Nutrition Education Consortium (IPNEC) developed a paradigm for PNSs that is designed to attract more physicians into the field; promulgated educational standards for fellowship training of PNSs; and established a unified mechanism for certifying PNSs, the American Board of Physician Nutrition Specialists (ABPNS). With a board of directors consisting of members nominated by 7 professional nutrition societies in addition to at-large members, the ABPNS incorporates broad participation by all professional nutrition societies that have substantial physician members. The ABPNS certificate is intended to be the premier comprehensive credential for physicians who wish to identify nutrition as an area of expertise. Certification is equally accessible to physicians with backgrounds in any of the specialties and subspecialties relevant to clinical nutrition. This article outlines the history and features of IPNEC and ABPNS and the consensus paradigm, training standards, and certification process they developed. We discuss achievements, opportunities, and challenges facing the maintenance of a consensus-based certification body in order to inform future initiatives designed to expand the number of physician nutrition specialists.

Disruptions in the organization of meal preparation and consumption among older cancer patients and their family caregivers.

OBJECTIVES: The purpose of this paper is to analyze the social organization of caring as gendered work as it relates to meal preparation and consumption activities surrounding older adult cancer patients and their caregivers. METHODS: Qualitative methods consisting of in-depth, semi-structured, face-to-face interviews with 30 older cancer patients (17 women and 13 men aged 68-90) and their caregivers were conducted separately. Participants were diagnosed with pancreatic, colon, breast, lymphoma, skin, and head and neck cancer. RESULTS: Major findings were that both patients and caregivers experienced distress surrounding food preparation and mealtime activities, and these varied according to the gender of both patients and caregivers and the relationship that existed between patients and caregivers. Of particular note, female patients experienced distress over not being able to fully participate in meal planning and cooking activities that were central to their self-identity. Related to this, male spouses experienced frustration over not being able to engage in cooking activities that met their wives' expectations. Female caregivers expressed tremendous discontent that the one they were caring for did not eat like they 'should'. DISCUSSION: Matters related to the organization of meals and food consumption activities may be a source of significant distress for patients and caregivers. Further research and greater attention from health care providers are warranted to evaluate the extent of such distress.

Effects of a reimbursement incentive on enrollment in a weight control program.

OBJECTIVE: The objective was to examine the effect of offering a reimbursement incentive on the percentage of inquirers who enrolled in a weight control program and on weight loss and program attendance among enrollees. RESEARCH METHODS AND PROCEDURES: We used a sequential control-intervention design to observe how inquirers of the University of Alabama at Birmingham EatRight Lifestyle Program responded to an enrollment incentive for potential 50% ($150) reimbursement of the total program fee if they attended 10 of 12 classes and lost at least 6% of their current body weight. Inquirers had to be adults with a BMI >or=30 kg/m(2), seeking information about a weight control program, and informed of the program cost. Outcomes included proportion of inquirers enrolled, overall number of classes attended, and weight loss. RESULTS: Of the 401 people who inquired during the study periods, 24.5% and 25.0% enrolled in the intervention and control periods, respectively. There was a trend toward higher attendance in the intervention group, compared with the control group; there were no differences in percentage of weight loss. The odds of attending >or=10 classes were 2.4 times as high, and both losing >6% body weight and attending >or=10 classes were three times as high in the intervention subjects compared with controls, although non-significant. DISCUSSION: The potential of earning a performance-based reimbursement incentive did not affect enrollment in the EatRight Lifestyle Program. Performance-based incentives may be an ideal mechanism for extending coverage of weight-loss interventions by insurers because of limited financial risk and improved adherence.

Training and certifying gastroenterologists as physician nutrition specialists.

Because nutrition is an integral aspect of the science and practice of gastroenterology, all gastroenterology fellows should receive training in core aspects of nutrition (level 1 training). Some gastroenterologists also wish to train more extensively in nutrition (level 2) and become physician nutrition specialists. The Intersociety Professional Nutrition Education Consortium, composed of representatives from eight national societies with significant nutrition interests, including the American Gastroenterological Association, and three credentialing bodies, has developed a paradigm and training requirements for physician-nutrition specialists that recognizes their varied backgrounds and areas of interest. Opportunities exist for gastroenterology fellows to obtain physician nutrition specialist training within their gastroenterology fellowships and to be eligible to take the Certification Examination for Physician Nutrition Specialists offered by the new American Board of Physician Nutrition Specialists.* This article reviews the development of consensus on subspecialty training for physicians in nutrition; it also encourages directors of gastroenterology fellowships to develop training opportunities and gastroenterology fellows to consider identifying nutrition as an area of emphasis for their careers.
