Use of next-generation metagenomic sequencing to determine the etiology of respiratory febrile illness in Malawian Children
Febrile illness in African children caused by sepsis, malaria and viral infection is a major public health challenge. Studies from Malawi show that viruses causing respiratory illness are diverse, involve coinfections and fluctuate seasonally. It is thus likely that studies done with multiplex molecular tests may not be truly reflective of all viruses circulating in the population. There is also little information available on the etiological agents of respiratory illness in rural areas in Malawi. Metagenomic next generation sequencing (mNGS) offers an unbiased approach to characterizing pathogens associated with respiratory illness, however, limited capacity for mNGS exists in Malawi. Dr. Bandawe and his mentorship team hypothesize that febrile respiratory illness in Malawian children is caused by a diversity of viral pathogens including some not previously described. The objective of the study is to use mNGS to identify viruses associated with respiratory infections in children presenting at two Malawian hospitals

Cost-Effective Normalization of Neuronal Dysfunction in Parkinson’s Disease
Parkinson’s disease is the second most common neurodegenerative disease and twice as prevalent in low- and middle income- countries (LMICs) compared to high income countries. However, the disease is rarely considered in global health discussions. Currently, expensive diagnostic imaging and complex surgical treatments are unfeasible in LMICs. New advancements in neurorecording and neuromodulation may provide an avenue for improved treatments of Parkinson’s disease in LMICs. Dr. Brown’s project hypothesizes that electroencephalography and transcranial electrical stimulation can measure and fix irregular brain waves, respectively, in Peruvian patients with Parkinson’s disease. This project is in collaboration with the Instituto Peruano de Neurociencias. The findings will lead to a better understanding of brain rhythms in Parkinson’s disease and the potential for new technologies to be a cost-effective treatment modality in LMICs.

Prescription and uptake antibiotic as prophylaxis to prevent STIs for MSM PrEP users in Vietnam
Men who have sex with men (MSM) in Vietnam are affected by HIV and sexually transmitted infections (STIs). While PrEP is effective for HIV prevention, high prevalence of bacterial STIs among PrEP participants in the country suggests an urgent need for interventions to prevent STIs within this population. Doxycycline prophylaxis has been shown to be an effective tool for preventing syphilis, gonorrhea, and chlamydia. This study will apply a mix-methods study exploring the readiness of both health care workers and MSM PrEP users to uptake doxycycline prophylaxis as a method for STIs prevention. Successful implementation of this study will be important to inform future implementation of doxycycline prescription for STI prophylaxis for MSM and those who have higher risk of STIs in Vietnam.

Mental health status of migrant workers in the tea plantation industry of South India - a mixed methods study
Migrant mental health issues are of global concern and unique socio-environmental and cultural barriers are attributed to higher prevalence of mental health issues among this population. Dr. Joseph will use a mixed methods approach to identify the mental health status and barriers to accessing mental health care among the migrant workers at the tea plantations in South India. Her study will also use qualitative techniques to understand the shared perceptions of key stakeholders regarding the unmet mental health needs of the migrant population working in the plantation sector. The study’s findings can help shed light on the social determinants of migrant mental health in India and pave the way for future research and policy implications. Inclusion of mental health screening and treatment in the basic health care package offered at the plantation hospitals, training of healthcare providers for early identification, and prompt treatment/counselling for mental illness are a few long-term implications that Dr. Joseph aims to achieve through the study.

Malnutrition Assessment among head and neck Cancer patients (MAC)
Despite advancement in cancer treatment, the concept of malnutrition in the management of head and neck cancer patients in East Africa has neither been well studied nor has it been incorporated in standard treatment guidelines or routine practice among oncologists. Kaduka et al (Journal of Nutritional Science. 2017; 6:e63.) showed that the rate of malnutrition and cachexia among cancer outpatients in Nairobi, Kenya is around 13.4%. Dr. Massawe’s team’s pilot cross sectional studies at a single site showed a higher proportion of around 40%. This yearlong cohort study aims at describing the baseline proportion, severity, and risk factors for malnutrition among head and neck cancer patients and developing a structured nutritional intervention program. The results are expected to serve as an important step towards establishing malnutrition treatment guidelines and prevention programs and pave the way for the formulation of cheap, culturally based and locally acceptable nutritional recipes for head and neck cancer patients

Health and economic evaluation of the implementation of the six-month model of HIV treatment in Mozambique
In 2022, the Mozambique Ministry of Health launched guidelines for a phased implementation of a model of care consisting of a six-month dispensing of antiretrovirals (6MM), a differentiated service delivery model for HIV treatment. Dr. Uetela and her team aim to evaluate the health and economic impact of this implementation. For the health impact evaluation, an uncontrolled interrupted time series design will be applied to compare retention in antiretroviral therapy (ART) and viral suppression 12 months after ART initiation, before and after the implementation of the 6MM model. For the economic evaluation, a dynamic transmission model, simulating heterosexual HIV transmission among the general population, will be used to conduct a cost-effectiveness analysis from the health system perspective. The results of this study will inform the Mozambique Ministry of Health of the health and economic impact of the implementation of the 6MM model, for informed decision-making on the scale-up of this intervention.

Association of pharmacogenomics markers in CYP3A4, CYP3A5, CYP2C19, UGT1A1, UGT1A4 and SLCO3A1 on the pharmacokinetics of rilpivirine and darunavir in HIV-positive women.
Rilpivirine (RPV) and darunavir (DRV) can be used as alternatives to the standard of care in the treatment of HIV/AIDS. Unfortunately, this is limited by poor virologic response in at least 10% of patients which is in turn associated with suboptimal drug concentrations. Studies have shown that genetic polymorphisms can influence the pharmacokinetics of both RPV and DRV. There is however limited data on the genotypic frequency of the perpetrator polymorphisms among black African populations despite the relevance in HIV/AIDS in the sub-Saharan African context. In this study, Dr. Nakalema seeks to identify and examine the correlation between single nucleotide polymorphisms (SNPs) in CYP3A4, CYP3A5, CYP2C19, UGT1A1, UGT1A4 and SLCO3A1 genes on the plasma concentration of RPV and DRV in HIV-positive women. This sub-study will build on existing work conducted at the Infectious Diseases Institute through the Contraceptive Implant Research Consortium for Low income countries.

Sukuu Tenabia Edziban Papa (STEP-uP): Promoting health and food security for Ghanaian adolescents through healthy school food environments
Adolescence is a period of physical, social, and cognitive development and nutrient-rich diets are essential to support optimal growth and development during this period. School environments can be important influencers of adolescent nutrition and health especially in Ghana where school attendance has been increasing steadily for adolescents. This project will use mixed methods to describe adolescent school food environments from the perspective of various stakeholders, understand how adolescents make food choices within their school environment, and analyze how these choices/environments influence adolescents’ experiences of food insecurity at school. The project will use Photovoice, a method in which adolescents visually communicate and tell stories about their food environments through photos. This will be accompanied by structured environmental observations, focus groups discussions with key stakeholders, and validated scales to quantitatively assess food insecurity.

Utility, Feasibility and Acceptability of a Point of Care Urine Tenofovir Assay to Monitor Treatment and Enhance Adherence to Anti-retroviral Therapy in People Living with HIV
With the Tenofovir-Lamivudine-Dolutegravir rollout as first-line anti-retroviral therapy (ART) in low-resource settings, non-adherence is the most common factor associated with virological failure. Achieving the 3rd UNAID target of 95% sustained viral suppression requires innovative approaches to support adherence. Self-reported adherence and pill counts tend to be unreliable. Identifying non-adherence to ART with an objective measure at the point of care would provide a crucial opportunity for early intervention. UCSF has helped develop a novel, low-cost urine test ($2/test) to identify tenofovir, indicative of short-term adherence to ART. Dr. Sebastian proposes to evaluate the usefulness of the urine test in improving ART adherence and predicting virological failure among PLWH attending a government-supported clinic in Bengaluru. She hopes this low-cost tool will enhance ART effectiveness by interpreting and enhancing adherence.

Culturally sensitive risk reduction strategies for cardiovascular disease centered on optimal uptake of evidence-based treatments among patients with multimorbidity in a resource constrained tribal setting – INTEGRATE
Multimorbidity, predominantly cardiovascular diseases (CVDs) are exponentially increasing in LMICs like India and the effects are multifold with higher risk to socio-economically disadvantaged (SED) populations. Management of CVDs is more complex in the presence of multimorbidity emphasizing the importance of systematic integration of management of chronic diseases. In India, where over one-third of the global tribal population resides, these marginalized communities face significant health disparities. Hence, Dr. Srinivasan proposes to conduct a mixed-methods research to comprehensively understand the characteristics, treatment patterns, and medication adherence for CVD. Through qualitative techniques, she will also delve into the factors that induce behavior change and foster optimum treatments for CVD in the context of multimorbidity. By doing so, she aims to develop novel, culturally sensitive, and patient-centered strategies that address the unique challenges of these tribal communities in India.

Chronic Kidney Disease Progression Among Older Adults Living with HIV at a Large HIV Care Facility in Uganda
With expanded access to antiretroviral therapy (ART), aging with HIV is now possible, however, it carries a risk of multimorbidity. People living with HIV (PLWH) are three-fold more likely to develop chronic kidney disease (CKD), estimated glomerular filtration rate [eGFR] ≤60mls/ min/1.73m2 than those without HIV. However, the rate of progression remains unknown unlike in the general population. This study aims to assess CKD progression among older PLWH aged ≥60 years in Uganda by 1) Evaluating the prevalence of albuminuria (spot urine albumin-to-creatinine ratio [UACR] ≥30 mg/g) and 2) Determining longitudinal eGFR change and its predictors among older PLWH aged ≥60 years in Uganda. secondarily, the recovery of renal function following the withdrawal of Tenofovir Disoproxil Fumarate (TDF) will be assessed. This study will provide baseline information on the rate of CKD progression in the aging HIV population which is key to informing kidney disease monitoring programs for this population.

Exposure assessment correlation between dietary pesticide intake and biomonitoring among children under five years in Kampala Metropolitan Area in Uganda
The proposed cross-sectional study that will be carried out among 100 households will establish a correlation between environmental and biomonitoring exposure assessment to pesticides in fruits and vegetables among children under 5 years in Kampala, Uganda. From each household, one child under 5 years will be selected. During the first visit, parents will be interviewed using a semi-structured questionnaire to collect socio-demographics, anthropometric, health symptoms, and pesticide use data. Parents will be asked to collect samples of foods their children consume for 24 hours and their urine in 500 ml polypropylene bottles. Collected samples will be picked up within 24 hours during the second visit. Samples will be analyzed using tandem liquid chromatography – mass spectrometry. Generalized estimating equations will be used to evaluate the relation between fruits and vegetable intake with specific individual pesticide metabolites biomarkers and their sum.

Dietary micronutrient deficiencies among HIV positive pregnant women in Western Kenya
HIV/AIDS and malnutrition are two of the leading causes of mortality in sub-Saharan Africa. Women of reproductive age living with HIV are at higher risk of suffering from malnutrition (caloric insufficiency and micronutrient deficiencies). Dr. Torres Aguilar’s project will use a cross-sectional, mixed methods study to assess the incidence and underlying causes of micronutrient deficiencies among pregnant and postpartum women in Western Kenya. His project will explore the barriers for access to micronutrients and determine factors associated with vitamin A, iron and folate dietary insufficiency. The second aim of the study will assess economic viability of different supplementation/fortification strategies to reduce micronutrient insufficiency.

Characterization of malaria drug and diagnostic resistance markers in refugee children in Uganda
Recent reports of mutations associated with partial resistance to artemisinins and gene deletions that mediate false negative rapid diagnostic tests seriously threaten malaria control in Africa. Due to conflicts, surveillance is impossible in many areas of Africa. Uganda hosts the largest refugee population, including individuals from South Sudan and Democratic Republic of Congo (DRC). Many of them enter Uganda with malaria infections, providing an opportunity to evaluate molecular markers of drug and diagnostic resistance in conflict populations. Dr. Tukwasibwe will collect samples from children entering Ugandan refugee camps adjacent to South Sudan and DRC, determine the prevalence of malaria parasitemia, genotype markers of drug and diagnostic resistance, and evaluate genetic relatedness of imported and local parasites. This data will provide useful information for policy makers, help guide treatment policies for arriving refugees, ensure effective treatment and reduce the spread of resistance.

Understanding cervical cancer stigma, HPV vaccination awareness and acceptance among adolescents and young adults living with HIV in India: a step towards the elimination of cervical cancer by 2030
There is a high HPV prevalence and increased risk of cervical cancer (CC) among Adolescents and Young Adults Living with HIV (AYALHIV). Early and unprotected sex, sexually transmitted infections, and smoking are factors associated with HPV infection among AYALHIV, owing to their socio-economic conditions, HIV disclosure, adherence, and lack of reproductive and sexual health counseling. Despite the proven safety and immunogenicity of quadrivalent HPV vaccine among female AYALHIV and its commercial availability in India, HPV vaccine is still not the part of National Immunization Program. India has the highest population of youth and AYALHIV but no studies have explored knowledge of CC and prevention strategies among AYALHIV in India. During her GloCal fellowship, Dr. Verma will explore awareness of CC, prevention strategies, and acceptance of HPV vaccination among AYALHIV. Findings could inform evidence-driven strategies to integrate HPV vaccination into existing HIV programs.

Nafisa Wara, UCLA
Nafisa Wara is a medical student at the University of California, Los Angeles (UCLA) David Geffen School of Medicine. Ms. Wara is passionate about using implementation science to inform the integration of preventive sexual and reproductive care for people of reproductive age in resource-limited settings. She graduated from Harvard University in 2019 and pursued postgraduate research in Durban, South Africa, where she worked with the AIDS Healthcare Foundation South Africa and Massachusetts General Hospital on the design and evaluation of community-based delivery models of HIV prevention and sexual health care. These years inspired her current work assessing the feasibility and acceptability of long-acting PrEP modalities (e.g., injectable cabotegravir, dapivirine vaginal ring) among pregnant and lactating people, on which she has collaborated with researchers at UCLA, the University of Cape Town (UCT), the University of Washington, and Kenyatta National Hospital (Kenya).

Development of patient-centered decision support to improve pre-exposure prophylaxis (PrEP) decision-making among pregnant and lactating people in Cape Town, South Africa
Despite high reported rates of daily oral pre-exposure prophylaxis (PrEP) uptake among pregnant and lactating people (PLP) in South Africa, individuals have reported substantial logistical and sociocultural barriers to adherence on daily oral PrEP. Long-acting PrEP modalities (e.g., eight-week injectable cabotegravir and four-week dapivirine vaginal ring) may mitigate barriers to adherence and persistence, and recent data show both high theoretical acceptability of injectable cabotegravir as PrEP among PLP, as well as continued interest by some in daily oral PrEP. With the approval and impending rollout of long-acting PrEP modalities in South Africa, there is an urgent need to integrate strategies that support PLP in choosing between PrEP modalities. Ms. Wara’s project will use mixed methods to engage with PLP and healthcare workers to inform the pre-implementation development of a patient-centered decision-support model for PrEP modality selection among PLP in Cape Town, South Africa.

Optimization of mHealth follow-up in Cameroon: A multi-methods approach
The project will assess a mobile phone-based (mHealth) follow-up tool for injured patients. The mHealth follow-up tool is a seven-item survey designed to identify patients in need of additional care after discharge. If the tool determines the patient is at high risk for a poor outcome after discharge, it recommends the patient return for an in-person exam. The project will utilize data collected by the Cameroon Trauma Registry (CTR); a registry used by ten hospitals across Cameroon. Specifically, the project will quantitatively evaluate the individual, socioeconomic, and clinical variables that influence patient participation in the mHealth follow-up survey tool and presentation for in-person exam. Furthermore, in-depth interviews with patients, emergency department staff, and research assistants will qualitatively assess the cultural competency of the mHealth tool. The findings will influence mHealth tool administration to ensure patient acceptability and maximize participation.

Beta-lactam allergy delabeling to improve infectious disease outcomes
A major component of antibiotic stewardship is the selection of the ideal medication for each infection. However, when a patient has an allergy to the ideal medication listed in their medical record, second-line treatment must be used. The use of second-line antibiotics can be associated with higher rates of failure, harsher side-effects, and development of antimicrobial resistance. Up to 10% of people have allergies to beta-lactam antibiotics listed in their medical record, but upon allergy testing, a vast majority can actually tolerate the medication. This is due to both erroneous initial diagnosis and natural desensitization. Recent treatment guidelines recommend testing patients with low-risk beta-lactam allergies, but a majority of the research supporting these recommendations has been completed in developed, western nations. This project will study the implementation of a beta-lactam allergy testing initiative in Hanoi, Vietnam.

The influence of digital health education on adolescent sexual and reproductive health knowledge and behaviors in Accra, Ghana
70% of sub-Saharan Africa is below the age of 30 and 40% is below the age of 15. As such, interventions that address health behaviors of young people have high potential impact in this region. Dr. Manu, Ms. Bhagavathi’s mentor, is a part of the ARISE Network Adolescent Health Study, a longitudinal study of 12,000+ adolescents across 10 sites, including 8 in sub-Saharan Africa and 2 in Asia. The study investigates health behaviors of adolescents, including substance and drug use, mental health, sexual behaviors and practices, STIs, pregnancy, and more. Ms. Bhagavathi’s project will be folded into the larger study and will analyze this population’s knowledge of sexual health as well as their knowledge and attitudes toward methods of family planning. This will culminate in the development of targeted text message-based interventions to improve knowledge of sexual health and individual empowerment in the use of family planning.
