: The optimal global health (GH) workforce should be racially and ethnically diverse, yet few persons from historically underrepresented minority (URM) groups in the United States participate in GH training programs. We conducted a study to explore barriers and facilitators for URM individuals to participate in the NIH Fogarty International Center’s GH Program for Fellows and Scholars (FGHFS), which offers yearlong international research training opportunities. We used an exploratory sequential mixed methods study design that used qualitative in-depth interviews (n = 18) to inform a subsequent quantitative online survey (n = 82). We assessed URM interest and engagement in GH training at three stages of FGHFS (applicants, alumni, and eligible persons who had not applied). Most participants in both phases were female, Black or African American, aged between 31 and 39 years, and had completed graduate or postgraduate training; a third or less were Hispanic. We identified four principal barriers to participation in GH training programs including lack of exposure to GH, lack of mentorship or support, challenges of global travel and work, and finances. The barriers compounded across training stages. Principal facilitators of training engagement included encouraging mentors and supportive families. Recommendations for increasing the participation of URM individuals in GH research training programs included increased financial support and exposure to GH in academic studies, as well as exposure to role models and mentors who can provide career advising in GH. Our findings suggest that early exposure, mentorship, and sufficient financial support will facilitate URMs’ entry into GH.

: Qualitative research methods are central to understanding many public health problems. However, capacity building for qualitative research is globally skewed toward high-income countries, with a significant skills deficit in low- and middle-income countries (LMICs). To address this imbalance and provide a model program, we developed the Qualitative Research Leaders (QRL) program, a pipeline program to increase qualitative research capacity in LMIC institutions and foster leadership in qualitative research. The QRL program is a collaboration between Emory University and Vanderbilt University in the United States and two LMIC institutions Kilimanjaro Christian Medical College in Tanzania and the Public Health Foundation of India. The program had five phases conducted over 12 months: 1) mentored study design sessions, 2) an in-country skill-building workshop, 3) mentored proposal development sessions, 4) a residential grant writing program in the United States, and 5) mentor matching for field implementation. Program evaluation results showed that the QRL program was effectively designed, and scholars valued the program components, learning formats, and session content. The program increased scholars’ knowledge, skills, and confidence as mentors in qualitative research. Furthermore, scholars demonstrated leadership in initiating postprogram research, mentoring, and teaching in qualitative research. Overall, scholars felt that the program could be extended to enable more time to internalize new knowledge and develop skills, and the role of in-country mentors could be expanded to further support scholars during fieldwork. In this article, we describe the components of the QRL program and its implementation, results of our program evaluation, and lessons learned for developing similar pipeline training programs.

: The University of Zambia (UNZA) Mentor Training Program is conducted annually to strengthen the mentorship capacity of postgraduate programs for the health professions. This intensive five-session course trains faculty members in the mentorship of students. Established by senior UNZA leaders and US-based collaborators, this program was designed to address gaps in mentorship identified at the institutional level. Faculty facilitators developed the course curriculum and used a train-the-trainer model to ensure program sustainability. Participants were faculty members who mentor PhD and Master of Medicine students. To assess the program’s impact, mentors and their mentees completed questionnaires on the mentor’s mentoring competencies at the end of the course and 1 year later. Competency scores were compared longitudinally to quantify potential changes in mentoring behaviors. Mentors and mentees alike noted mentor growth in all competency domains from postcourse to 1 year later, providing evidence of a trend toward improvement in mentorship and that the program may have sustainable and positive effects on mentoring behaviors over time. Salient areas of growth corresponded to emphasized topics and discussions, including addressing diversity, aligning expectations, assessing capacities, motivating mentees, and fostering independence. These findings suggest that mentors internalized this content and transferred it to behavior change. The behavior changes may reveal a larger change in the institutional environment around the mentoring of students. The UNZA Mentor Training Program appears to have sustained impact after a year and should bode well for future benefits to students, faculty, and the institution.

In this mixed-methods study, we explore themes that emerged from a survey assessing the programmatic experiences of mentors and administrators at institutions in low- and middle-income countries (LMICs) hosting trainees supported by the Fogarty International Center’s Global Health Program for Fellows and Scholars. A total of 89 of 170 potential respondents representing 31 countries completed the survey (response rate, 52.4%). There was agreement among respondents that their institutions received sufficient funds to support trainees and had the capacity to manage operational and financial aspects of the program. A majority also agreed that both LMIC and U.S. trainees were beneficial to the host institutions, and that trainee projects were relevant to the needs of the host country. Respondents felt that program benefits to LMIC trainees could be improved by increasing the research consumables budget, increasing the flexibility of program timelines, and increasing engagement between LMIC and U.S. trainees and institutions. Respondents indicated that both U.S. and LMIC trainees behaved professionally (including demonstrating respectful and ethical behavior) and took appropriate initiative to conduct their research projects. Findings from this study will help inform innovations to similar training initiatives that will enhance sustainability and improve program performance, and will be responsive to local needs.

Strong cultures of mentorship and research remain underdeveloped at many African universities, threatening future knowledge generation essential for health and development on the continent. To address these challenges, a mentorship program was developed in 2018 at the University of Zambia with an aim to enhance the institutional culture of mentorship and to build institutional capacity through an innovative 'train the trainer' faculty development model. In this study, we documented perceptions of lived experiences related to mentorship culture by following trainers and trainees and their mentees over two years. We analyzed these perceptions to assess changes in institutional attributes regarding mentorship. We identified positive change in institutional culture towards mentorship, and this change appeared sustainable over time. However, a slight decrease in indicators for year two emphasizes the need for a continued culture of learning rather than assuming that one-off training will be sufficient to change culture.

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. 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. 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. 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.

: 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.

PURPOSE: Cancer occurrence is increasing in Africa, although research has lagged. The objective of this review was to analyze cancer research outputs from Africa, with a particular focus on Zambia. METHODS: We searched PubMed for published cancer-related articles from African countries. All articles reporting on cancer in Africa were considered. We conducted analyses to explore correlations between cancer research output and total population, gross domestic product, and new cancer cases recorded in 2020. For Zambia articles, we also analyzed cancer types and time trends. RESULTS: A total of 48,487 cancer-related publications from Africa were identified, with nearly half coming from Egypt (13,372; 28%) and South Africa (9,393; 19%). Cancer research output correlated significantly with country population (Spearman's correlation coefficient 0.74; P < .001) and the number of new cancer cases recorded in 2020 (Spearman's correlation coefficient 0.77; P < .001). Standardized by population size, Western Sahara (0.576), Seychelles (0.244), Tunisia (0.239), South Africa (0.158), and Egypt (0.131) had the highest overall output per 1,000 population. A total of 244 publications were from Zambia; the most studied cancers were cervical (25%), Kaposi sarcoma (24%), and breast (10%). Although an increase in cancer research output from Zambia was noted, only 33% of publications were first or last authored by Zambians. The major limitation of this review is that the evaluation was based on a single electronic database, PubMed. CONCLUSION: Cancer research output from Africa is very low, with many of the publications concentrated in a few countries. There is an urgent need to invest in both human resources and infrastructure to increase cancer research output from African countries, particularly in less populous countries.
