RESUMO

Psychological distress is increasingly recognized as a barrier to engagement in HIV care, resulting in poor HIV outcomes. HIV-related stigma is a potential driver of distress in people living with HIV (PLWH). We conducted a prospective cohort study in 288 PLWH who newly initiated ART in a Nigeria. We assessed overall stigma (range 40-160) and four stigma subtypes (personalized, disclosure, negative self-image, and public stigma) at enrollment, and assessed psychological distress at enrollment, 6, and 12-months after ART initiation. We used logistic regression to assess the relationship between stigma and 12-month psychological distress. Overall stigma was high (102.34 ± 5.65) and was higher in both unmarried patients (p < 0.01) and those who had not disclosed their HIV status to anyone at enrollment (p < 0.01). Higher overall stigma (OR: 1.05, 95% CI 1.00-1.09) and personalized stigma (OR:1.08, 95% CI 1.00-1.16) were associated with higher odds of psychological distress at 12-months. Conclusions: Overall stigma levels were high in a cohort of PLWH initiating care in Nigeria. Higher stigma was associated with psychological distress. These data support the need for integration of measures to reduce stigma and psychological distress in the care of PLWH.

RESUMO

OBJECTIVE: Our objective was to assess the prevalence and patterns of mobility among people with HIV (PWH) in Tennessee and its impact on HIV care outcomes. DESIGN: Retrospective cohort study. METHODS: We combined residential address and HIV surveillance data from PWH in Tennessee from 2016 to 2018. Using Poisson regression, we estimated associations between in-state mobility (change in address or total miles moved) in 1 year and outcomes in the subsequent year; retention: having two CD4 + /HIV RNA values (labs) in a calendar year at least 3 months apart, loss to follow-up (LTFU): having labs at baseline but not the subsequent year, and viral suppression: HIV RNA less than 200 copies/ml. We applied a kernel density estimator to origin-destination address lines to visualize mobility patterns across demographic subgroups. RESULTS: Among 17 428 PWH [median age 45 years (interquartile range; IQR 34-53)], 6564 (38%) had at least one move. Median miles moved was 8.9 (IQR 2.6-143.4)). We observed in-state movement between major cities (Chattanooga, Knoxville, Memphis and Nashville) and out-of-state movement to and from Georgia and Florida. Having at least one in-state move was associated with a decreased likelihood of retention [adjusted relative risk (aRR) = 0.91; 95% confidence interval (CI) 0.88-0.95], and an increased risk of LTFU (aRR = 1.17; 95% CI 1.04-1.31, two to three moves vs. none). Greater distance moved in-state was associated with decreased retention and increased LTFU (aRR = 0.53; 95% CI 0.49-0.58, aRR = 2.52; 95% CI 2.25-2.83, respectively for 1000 vs. 0 miles). There was no association between mobility and viral suppression. CONCLUSION: Mobility is common among PWH in Tennessee and is associated with initial poor engagement in HIV care.

RESUMO

BACKGROUND: Poor medication adherence is a major barrier to HIV control among youth living with HIV (Y-PLWH). The PEERNaija application (app) is an adapted smartphone app grounded in social cognitive and contigency management theories and designed to harness peer-based social incentives and conditional financial incentives to promote medication adherence. The app delivers a multifaceted medication adherence intervention including (1) peer-based social incentives, (2) financial incentives, (3) virtual peer social support, and (4) early clinic-based outreach for non-adherent Y-PLWH. A pilot trial of the app will be conducted in Nigeria, Africa's most populous country with the 4th largest HIV epidemic, and home to 10% of the world's four million Y-PLWH. METHODS: In this randomized controlled trial, we will compare implementation outcomes (feasibility, acceptability, appropriateness measured via validated scales, enrollment and application installation rates, feedback surveys and focus group discussions with participants, and back-end application data), and preliminary efficacy (in improving medication adherence and viral suppression) of the PEERNaija app at 6 months. Participants in Arm 1 (PEERNaija) will receive daily medication reminders, peer-based social incentives, and virtual peer social support. Participants in Arm 2 (PEERNaija +) will additionally receive a conditional financial incentive based on their adherence performance. Eligibility for Y-PLWH includes (1) being aged 14-29 years, (2) being on ART, (3) owning a smartphone, (4) being willing to download an app, and (5) being able to read simple text in English. DISCUSSION: This study will serve as the basis for a larger intervention trial evaluating the PEERNaija app (and the integration of mHealth, incentive, and peer-support-based strategies) to improve HIV outcomes in a critically important region of the world for Y-PLWH. TRIAL REGISTRATION: ClinicalTrials.gov. NCT04930198. First submitted date: May 25, 2021. Study start: August 1, 2021, https://clinicaltrials.gov/ . PROTOCOL VERSION: January 21, 2022.

RESUMO

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.

RESUMO

Black men comprise most new HIV infections in the Southern United States and have worse HIV outcomes than their non-Black counterparts. We developed an academic-community partnership in Nashville, Tennessee, to explore opportunities to improve HIV outcomes for Black men. We recruited barbers to an HIV training and focus group discussion about prevention and potential barber/barbershop-based strategies to address HIV-related needs for Black men. We assessed HIV knowledge and stigma with validated scales and conducted thematic analysis on discussion transcripts. HIV-related stigma was low (1.8 of 15 points [SD = 1.69]) among 13 participants of unknown HIV status (12 men and one woman). HIV knowledge increased among eight (67%) participants after receiving a brief HIV didactic. Participants described general health care barriers (e.g., the social norm that Black men do not go to the doctor until they are "damn near dead"), fears about unwanted HIV disclosure when seeking HIV testing or care, and community fears about negative stereotypes associated with HIV. Participants expressed enthusiasm about receiving more HIV-related training and utilizing communication skills and client/community relationships to serve as health educators and navigators. Barbers highlighted opportunities to disseminate HIV information in barbershops and combine HIV interventions with other health issues, such as COVID-19, and suggested that these interventions may help reduce HIV-related stigma. Our findings suggest that barbers and barbershops are an underutilized resource for disseminating HIV-related health information and engaging Black men in HIV and other important prevention and care activities such as COVID-19.

RESUMO

BACKGROUND: Few studies have longitudinally assessed psychological distress among people with HIV (PWH) initiating ART in resource-limited settings. METHOD: Baseline, 6-month, and 12-month psychological distress were measured in a Nigerian cohort newly initiating therapy; the relationship between baseline factors and psychological distress at 12 months was assessed; and the association between psychological distress at 12 months and care retention or immunologic failure was determined. RESULTS: Among 563 patients, median age was 38 years (IQR: 33-46 years), 62% were female, and 51% were married. Psychological distress increased from 3% at baseline to 34% at 12 months. Age (aOR 1.28, 95% CI 1.06-1.56), female sex (aOR 2.89, 95% CI 1.93-4.33), lack of disclosure (aOR 4.32, 95% CI 2.48-7.51), and time on ART (6 months [aOR 6.91, 95% CI 3.14-15.18] and 12 months [aOR 32.63, 95% CI 16.54-64.36]) were associated with psychological distress while being married (OR 0.42, 95% CI 0.30-0.61) was associated with reduced odds. Tweve-month psychological distress was associated with increased risk of immunologic failure (aOR 2.22, 95% CI 1.31-3.82). CONCLUSION: The risk of psychological distress increased 30-fold in the first year on therapy in PWH in Nigeria.

RESUMO

BACKGROUND: Youth born outside of the US with perinatally acquired HIV infection (YBoUS-PHIV) account for most children living with HIV in the US, but there are few data characterizing their care outcomes. METHODS: We conducted a retrospective study of YBoUS-PHIV receiving care across 3 HIV clinics in the Southeastern US between October 2018 and 2019. Primary outcomes were retention in care and viral suppression defined as (1) proportion of suppressed viral loads (VLs) and (2) having all VLs suppressed (definition 1 presented in the abstract). Primary predictors were age, adoption and disclosure status (full, partial and none/unknown). Multivariable logistic regression and χ 2 tests were used to test for associations with care outcomes. Analysis of disclosure status was restricted to youth greater than or equal to 12 years. RESULTS: The cohort included 111 YBoUS-PHIV. Median age was 14 years (interquartile range, 12-18), 59% were female, and 79% were international adoptees. Overall, 84% of patients were retained in care, and 88% were virally suppressed at each VL measurement. Adopted youth were more likely to be virally suppressed than nonadopted youth [odds ratio (OR), 7.08; P < 0.01] although the association was not statistically significant in adjusted analysis (adjusted OR, 4.26; P = 0.07). Neither age nor adoption status was significantly associated with retention. Among 89 patients greater than or equal to 12 years, 74% were fully disclosed of their HIV status, 12% were partially disclosed, and 13% had not started the disclosure process. There was no significant difference in retention or viral suppression by disclosure status. CONCLUSIONS: YBoUS-PHIV achieved high rates of retention and viral suppression. Adopted youth may be more likely to achieve viral suppression which may reflect the need for tailored interventions for nonadopted youth.

RESUMO

OBJECTIVE: We assessed trends and identified individual- and county-level factors associated with individual linkage to HIV care in Tennessee (TN). METHODS: TN residents diagnosed with HIV from 2012-2016 were included in the analysis (n = 3,751). Individuals were assigned county-level factors based on county of residence at the time of diagnosis. Linkage was defined by the first CD4 or HIV RNA test date after HIV diagnosis. We used modified Poisson regression to estimate probability of 30-day linkage to care at the individual-level and the contribution of individual and county-level factors to this outcome. RESULTS: Both MSM (aRR 1.23, 95%CI 0.98-1.55) and women who reported heterosexual sex risk factors (aRR 1.39, 95%CI 1.18-1.65) were more likely to link to care within 30-days than heterosexual males. Non-Hispanic Black individuals had poorer linkage than White individuals (aRR 0.77, 95%CI 0.71-0.83). County-level mentally unhealthy days were negatively associated with linkage (aRR 0.63, 95%CI: 0.40-0.99). CONCLUSIONS: Racial disparities in linkage to care persist at both individual and county levels, even when adjusting for county-level social determinants of health. These findings suggest a need for structural interventions to address both structural racism and mental health needs to improve linkage to care and minimize racial disparities in HIV outcomes.

RESUMO

BACKGROUND: Immunization is a cost-effective public health strategy to reduce vaccine preventable disease, especially in childhood. METHODS: This paper reports the philosophy, service delivery, achievements and lessons learned from an immunization program in rural Nigeria privately financed via a corporate social responsibility initiative from GlaxoSmithKline Biologicals. RESULTS: The immunization program served the community for a 16-y period extending from 1998 until 2015, resulting in an increase in age-appropriate immunization coverage from 43% to 78%. CONCLUSION: In its success, this immunization program exemplified the importance of early and sustained community engagement, integration of strategies to optimize implementation outcomes and effective team building well before some of these principles were accepted and codified in the literature. The project also underscores the important role that the private sector can bring to achieving critical immunization goals, especially among underserved populations and provides a model for successful public-private partnership.

RESUMO

INTRODUCTION: Guided by an intersectional approach, we assessed the association between social categories (individual and combined) on time to linkage to HIV care in Tennessee. METHODS: Tennessee residents diagnosed with HIV from 2012-2016 were included in the analysis (n=3750). Linkage was defined by the first CD4 or HIV RNA test date after HIV diagnosis. We used Cox proportional hazards models to assess the association of time to linkage with individual-level variables. We modeled interactions between race, age, gender, and HIV acquisition risk factor (RF), to understand how these variables jointly influence linkage to care. RESULTS: Age, race, and gender/RF weAima A. Ahonkhaire strong individual (p < 0.001 for each) and joint predictors of time to linkage to HIV care (p < 0.001 for interaction). Older individuals were more likely to link to care (aHR comparing 40 vs. 30 years, 1.20, 95%CI 1.11-1.29). Blacks were less likely to link to care than Whites (aHR= 0.73, 95% CI: 0.67-0.79). Men who have sex with men (MSM) (aHR = 1.18, 95%CI: 1.03-1.34) and heterosexually active females (females) (aHR = 1.32, 95%CI: 1.14-1.53) were more likely to link to care than heterosexually active males. The three-way interaction between age, race, and gender/RF showed that Black males overall and young, heterosexually active Black males in particular were least likely to establish care. CONCLUSIONS: Racial disparities persist in establishing HIV care in Tennessee, but data highlighting the combined influence of age, race, gender, and sexual orientation suggest that heterosexually active Black males should be an important focus of targeted interventions for linkage to HIV care.

RESUMO

PURPOSE OF REVIEW: Clinical trials represent a bedrock for measuring efficacy of interventions in biomedical research, but recruitment into clinical trials remains a challenge. Few data have focused on recruitment strategies from the perspective of clinical trial teams, especially in low- and middle-income countries (LMIC), where HIV is most prevalent. RECENT FINDINGS: We summarized data from the literature and our experience with recruitment for the Renal Risk Reduction trial, aimed at reducing risk of kidney complications among people living with HIV in Nigeria. Using an implementation science framework, we identified strategies that contributed to successful clinical trial recruitment. For strategies that could not be categorized by this framework, we summarized key features according to selected action, actor, target, context, and time. We identified how these identified strategies could map to subsequent implementation outcomes at the patient and provider/health system level, as well as capacity-building efforts to meet needs identified by LMIC partners, which is a priority for success. Our experience highlights the importance of considering implementation outcomes, and the strategies necessary to achieve those outcomes early, in the planning and execution of clinical trials. Clinical trial recruitment can be optimized via methodologies grounded in implementation science.

RESUMO

OBJECTIVE: As master of science in health informatics (MSc HI) programs emerge in developing countries, quality assurance of these programs is essential. This article describes a comprehensive comparative analysis of competencies covered by accredited MSc HI programs in the East African common labor and educational zone. MATERIALS AND METHODS: Two reviewers independently reviewed curricula from 7 of 8 accredited MSc HI university programs. The reviewers extracted covered competencies, coding these based on a template that contained 73 competencies derived from competencies recommended by the International Medical Informatics Association, plus additional unique competencies contained within the MSc HI programs. Descriptive statistics were used to summarize the structure and completion requirements of each MSc HI program. Jaccard similarity coefficient was used to compare similarities in competency coverage between universities. RESULTS: The total number of courses within the MSc HI degree programs ranged from 8 to 22, with 35 to 180 credit hours. Cohen's kappa for coding competencies was 0.738. The difference in competency coverage was statistically significant across the 7 institutions (P = .012), with covered competencies across institutions ranging from 32 (43.8%) to 49 (67.1%) of 73. Only 4 (19%) of 21 university pairs met a cutoff of over 70% similarity in shared competencies. DISCUSSION: Significant variations observed in competency coverage within MSc HI degree programs could limit mobility of student, faculty, and labor. CONCLUSIONS: Comparative analysis of MSc HI degree programs across 7 universities in East Africa revealed significant differences in the competencies that were covered.

RESUMO

BACKGROUND: HIV is the leading cause of death for youth in Sub-Saharan Africa (SSA). The rapid proliferation of smart phones in SSA provides an opportunity to leverage novel approaches to promote adherence to life-saving antiretroviral therapy (ART) for adolescents and young adults living with HIV (AYA-HIV) that go beyond simple medication reminders. METHODS: Guided by the Integrate, Design, Assess and Share (IDEAS) framework, our multidisciplinary team developed a peer-based mHealth ART adherence intervention-PEERNaija. Grounded in Social Cognitive Theory, and principles of contingency management and supportive accountability, PEERNaija delivers a multi-faceted behavioral intervention within a smartphone application to address important obstacles to adherence. RESULTS: PEERNaija was developed as a gamified Android-based mHealth application to support the behavioral change goal of improving ART adherence among AYA-HIV within Nigeria, a low- and middle- income country (LMIC). Identified via foundational interviews with the target population and review of the literature, key individual (forgetfulness and poor executive functioning), environmental (poor social support) and structural (indirect cost of clinic-based interventions) barriers to ART adherence for AYA-HIV informed application features. Further informed by established behavioral theories and principles, the intervention aimed to improve self-efficacy and self-regulation of AYA-HIV, leverage peer relationships among AYA to incentivize medication adherence (via contingency management, social accountability), provide peer social support through an app-based chat group, and allow for outreach of the provider team through the incorporation of a provider application. Gamification mechanics incorporated within PEERNaija include: points, progress bar, leaderboard with levels, achievements, badges, avatars and targeted behavior change messages. PEERNaija was designed as a tethered mobile personal health record application, sharing data to the widely deployed OpenMRS electronic health record application. It also uses the secure opensource Nakama gamification platform, in line with Principles of Digital Development that emphasize use of opensource systems within LMICs. CONCLUSIONS: Theory-based gamified mHealth applications that incorporate social incentives have the potential to improve adherence to AYA-HIV. Ongoing evaluations of PEERNaija will provide important data for the potential role for a gamified, smartphones application to deliver multifaceted adherence interventions for vulnerable AYA-HIV in SSA.

RESUMO

OBJECTIVE: The International Medical Informatics Association (IMIA) has provided recommendations on Education in Biomedical and Health Informatics (BMHI) as guidance on competencies relevant to education of BMHI specialists. However, it remains unclear how well these competencies have been adopted to guide emerging degree programs in low- and middle-income countries (LMICs). We evaluated comprehensiveness of IMIA-recommended competency coverage by Masters in Health Informatics (MSc HI) programs in East Africa. MATERIALS AND METHODS: Two investigators independently reviewed curricula for seven accredited MSc HI university programs in the East Africa region to extract covered competencies using an instrument based on the IMIA education recommendations. Descriptive statistics were used to determine competency coverage by institution and across institutions and by IMIA-defined competency domains. Duplication of competency coverage in courses within each curriculum was also evaluated. Multivariable logistic regression was used to test whether coverage of IMIA-recommended competencies differed between institutions. RESULTS: Cohen's Kappa for coding competencies within courses was 0.738 (95% CI, 0.713-0.764). Coverage of the 40 recommended required IMIA competencies by institutional curricula ranged from 25 (62.5%) to 39 (97.5%) (p < 0.0001), with only 18 (45%) of these competencies covered by all seven institutions. No significant variations in competency coverage were observed between the domains of information sciences (83.7%), health sciences (71.4%), and core BMHI competencies (83.5%) (p = 0.13). On average, each competency was covered by 3.06 courses in each curriculum (range 0 - 14). Curricula also contained 25 additional competencies not part of the IMIA recommendations, 15 of which were found only within the curriculum of a single institution. DISCUSSION: There is significant variability in coverage of IMIA-recommended competencies across MSc HI curricula evaluated, with observed duplication of competency coverage within each curriculum. The additional competencies uncovered that were not part of the IMIA-recommendations were not universally shared across institutions. CONCLUSION: The IMIA education recommendations provide a relevant, comprehensive reference guide for developing and improving health informatics degree programs within LMIC settings. Variability in competency coverage needs to be addressed for institutions within similar educational and labor regions.

RESUMO

BACKGROUND: Symptom management is an important component of HIV care. But symptom patterns and how they affect engagement with HIV care and treatment services have not been adequately explored in the era of increased HIV treatment scale-up. We investigated the relationship between symptom patterns among people living with HIV (PLHIV) and 12 months retention in care, within the context of other clinical and demographic characteristics. METHODS: Retrospective cohort analysis of 5114 PLHIV receiving care within a large HIV treatment program in Nigeria. We assessed the prevalence and burden of baseline symptoms reported during routine clinic visits from January 2015 to December 2017. Multivariable regression was used to identify relationships between 12-month retention and symptom dimensions (prevalence and burden) while controlling for demographic and other clinical variables. RESULTS: Increasing symptom burden was associated with higher likelihood of retention at 12 months (adjusted odds ratio [aOR] = 1.19 [95% confidence interval, CI: 1.09-1.29]; P < .001) as was the reporting of skin rashes/itching symptom (aOR = 2.59 [95% CI: 1.65-4.09]; P < .001). Likelihood of retention reduced with increasing World Health Organization (WHO) Clinical staging, with CD4 ≥500 cells/mL and self-reported heterosexual mode of HIV transmission. Conclusions: Symptom dimensions and standardized clinical/immunological measures both predicted retention in care, but effects differed in magnitude and direction. Standardized clinical/immunological measures in HIV care (eg, WHO clinical staging and CD4 count categories) can mask important differences in how PLHIVs experience symptoms and, therefore, their engagement with HIV care and treatment. Symptom management strategies are required alongside antiretroviral treatment to improve outcomes among PLHIV, including retention in care.

RESUMO

One of the most glaring deficiencies in the current assessment of mortality risk is the lack of information concerning the impact of familial longevity. In this work, we update estimates of sibling relative risk of living to extreme ages using data from more than 1,700 sibships, and we begin to examine the trend for heritability for different birth-year cohorts. We also build a network model that can be used to compute the increased chance for exceptional longevity of a subject, conditional on his family history of longevity. The network includes familial longevity from three generations and can be used to understand the effects of paternal and maternal longevity on an individual's chance to live to an extreme age.

RESUMO

BACKGROUND: Hypoxic-ischemic encephalopathy (HIE) is a major cause of morbidity in survivors. Therapeutic hypothermia (TH) is the only available intervention, but the protection is incomplete. Preclinical studies of HIE/TH in the rodent have relied on the postnatal day (P) 7 rat whose brain approximates a 32-36 wk gestation infant, less relevant for these studies. We propose that HIE and TH in the term-equivalent P10 rat will be more translational. METHODS: P10-11 rat pups were subjected to unilateral hypoxia-ischemia (HI) and 4 h recovery in normothermic (N) or hypothermic (TH) conditions. Brain damage was assessed longitudinally at 24 h, 2 wk, and 12 wk. Motor function was assessed with the beam walk; recognition memory was measured by novel object recognition. RESULTS: Neuroprotection with TH was apparent at 2 and 12 wk in both moderately and severely damaged animals. TH improved motor function in moderate, but not severe, damage. Impaired object recognition occurred with severe damage with no evidence of protection of TH.
