Neighborhood characteristics and HIV treatment outcomes: A scoping review.

Recognizing challenges faced by people living with HIV is vital for improving their HIV treatment outcomes. While individual-level interventions play a crucial role, community factors can shape the impact of individual interventions on treatment outcomes. Understanding neighborhood characteristics' association with HIV treatment outcomes is crucial for optimizing effectiveness. This review aims to summarize the research scope on the association between neighborhood characteristics and HIV treatment outcomes. The databases PubMed, CINAHL (EBSCOhost), Embase (Elsevier), and PsychINFO (EBSCOhost) were searched from the start of each database to Nov 21, 2022. Screening was performed by three independent reviewers. Full-text publications of all study design meeting inclusion criteria were included in the review. There were no language or geographical limitations. Conference proceedings, abstract only, and opinion reports were excluded from the review. The search yielded 7,822 publications, 35 of which met the criteria for inclusion in the review. Studies assessed the relationship between neighborhood-level disadvantage (n = 24), composition and interaction (n = 17), social-economic status (n = 18), deprivation (n = 16), disorder (n = 8), and rural-urban status (n = 7) and HIV treatment outcomes. The relationship between all neighborhood characteristics and HIV treatment outcomes was not consistent across studies. Only 7 studies found deprivation had a negative association with HIV treatment outcomes; 6 found that areas with specific racial/ethnic densities were associated with poor HIV treatment outcomes, and 5 showed that disorder was associated with poor HIV treatment outcomes. Three studies showed that rural residence was associated with improved HIV treatment outcomes. There were inconsistent findings regarding the association between neighborhood characteristics and HIV treatment outcomes. While the impact of neighborhood characteristics on disease outcomes is highly recognized, there is a paucity of standardized definitions and metrics for community characteristics to support a robust assessment of this hypothesis. Comparative studies that define and assess how specific neighborhood indicators independently or jointly affect HIV treatment outcomes are highly needed.

Utilization of opportunistic cervical cancer screening in Nigeria.

BACKGROUND: While various interventions have been conducted to decrease cervical cancer's burden in Nigeria, no study has examined the trends in cervical cancer screening uptake over time. The present study sought to fill this gap in knowledge using data collected at Jos University Teaching Hospital (JUTH) in Nigeria. METHODS: Data collected continuously between 2006 and 2016 were analyzed to identify trends in screening uptake, changes in risk factors for cervical cancer, and to identify factors for women screened at Jos University Teaching Hospital (JUTH) in Jos, Nigeria. Categorical analyses and logistic regression models were used to describe patient characteristics by year, and to identify factors associated with repeated screening uptake. RESULTS: A total of 14,088 women who were screened between 2006 and 2016 were included in the database; 2,800 women had more than one screening visit. Overall, screening uptake differed significantly by year. On average women were first screened at age 38. About 2% of women screened were women living with HIV. Most women (86%) had normal pap smear at first screening, with the greatest decreased risk of abnormalities observed between 2011 and 2014. Odds of a follow-up screening after a normal result decreased significantly between 2008 and 2016 compared to women screened in 2006 and 2007. Finally, women living with HIV had increased odds of follow-up screening after having a normal pap smear. CONCLUSIONS: These findings contribute to our understanding of the potential social and health system barriers to cervical cancer control in Nigeria. The findings may assist policy makers to design interventions to increase access and compliance to recommended screening schedules in this vulnerable population.

The impact of the COVID-19 pandemic on routine HIV care and cervical cancer screening in North-Central Nigeria.

INTRODUCTION: Cervical cancer is the fourth most diagnosed cancer among women globally, with much of the burden being carried by women in limited-resource settings often worsened by the high prevalence of HIV. Furthermore, the COVID-19 pandemic disrupted organized screening efforts and HIV management regimens worldwide, and the impact of these disruptions have not been examined in these settings. The purpose of this paper is to describe whether uptake of cervical cancer screening and HIV management changed before, during, and since the COVID-19 pandemic in North-Central Nigeria. METHODS: Longitudinal healthcare administration data for women who obtained care between January 2018 and December 2021 were abstracted from the AIDS Prevention Initiative Nigeria (APIN) clinic at Jos University Teaching Hospital. Patient demographics, pap smear outcomes, and HIV management indicators such as viral load and treatment regimen were abstracted and assessed using descriptive and regression analyses. All analyses were conducted comparing two years prior to the COVID-19 pandemic, the four quarters in 2020, and the year following COVID-19 restrictions. RESULTS: We included 2304 women in the study, most of whom were between 44 and 47 years of age, were married, and had completed secondary education. About 85% of women were treated with first line highly active retroviral therapy (HAART). Additionally, 84% of women screened using pap smear had normal results. The average age of women who sought care at APIN was significantly lower in Quarter 3, 2020 (p = 0.015) compared to the other periods examined in this study. Conversely, the average viral load for women who sought care during that period was significantly higher in adjusted models (p < 0.0001). Finally, we determined that the average viral load at each clinic visit was significantly associated with the period in which women sought care. CONCLUSIONS: Overall, we found that COVID-19 pandemic mitigation efforts significantly influenced women's ability to obtain cervical cancer screening and routine HIV management at APIN clinic. This study buttresses the challenges in accessing routine and preventive care during the COVID-19 pandemic, especially in low-resource settings. Further research is needed to determine how these disruptions to care may influence long-term health in this and similar at-risk populations.

The impact of COVID-19 on academic performance among college-level students.

Objective: The objective of this study is to assess the impact of COVID-19 on university students' academic performance. Participants: Our sample consisted of students 18 years old and above enrolled at least part-time during the Spring 2020 semester. Methods: This cross-sectional survey examined the individual, social, and economic impacts of COVID-19 on academic performance. We examined factors associated with a change in GPA between the two semesters. Results: Most students reported no change in GPA. Students of color had significantly increased odds of reporting a decrease in GPA than non-Hispanic White students (OR = 2.70, 95% CI: 1.01, 7.16). Students who had someone close to them test positive for COVID-19 had increased odds of reporting a decrease in GPA (OR = 1.85, 95% CI: 0.55, 5.93). Conclusion: Higher learning institutions may need to develop strategies to improve support for students that have been socio-economically impacted by COVID-19.

A Rasch analysis assessing the reliability and validity of the Arizona CoVHORT COVID-19 vaccine questionnaire.

BACKGROUND: Despite the widespread availability of COVID-19 vaccines in the United States, many that have chosen not to be vaccinated have done so because of vaccine hesitancy. This highlights the need for tools that accurately capture the knowledge, attitudes, and beliefs towards COVID-19 vaccines, and provide steps toward improving vaccine acceptance. METHODS: Participants of the Arizona CoVHORT (COVID-19 Cohort) received a one-time, electronic based cross-sectional questionnaire intended to capture underlying motivations regarding vaccination, as well as hesitations that may prevent people from getting vaccinated. Rasch analysis was conducted among 4703 CoVHORT participants who had completed the vaccine questionnaire to assess questionnaire reliability and validity. Response categories were grouped to optimize scale functioning and to ensure independent probabilities of participant endorsement. RESULTS: A total of 4703 CoVHORT participants completed the questionnaire, of whom 68% were female, and who had a mean age of 48 years. Participants were primarily White (90%), highly educated (63% with a college degree or above, with most respondents (45%) having an income of more than $75,000 per annum. The results indicated the questionnaire has good reliability and construct validity for assessing attitudes and beliefs about the COVID-19 vaccines. In-fit mean-squares for included items ranged from 0.61 to 1.72 and outfit mean-squares ranged from 0.56 to 1.75, and correlation coefficients ranged from 0.25 to 0.75. The person-item map indicated normal distribution of logit scores measuring perceptions about COVID-19 vaccinations. CONCLUSIONS: The CoVHORT vaccine questionnaire demonstrated satisfactory reliability and construct validity in assessing attitudes and beliefs about COVID-19 vaccines. Overall results provide a starting point for a reliable and valid tool to assess knowledge and perceptions about COVID-19 vaccination, ultimately providing public health professionals with an instrument to assess the factors that are associated with vaccine acceptance or hesitancy.

Economic evaluation using dynamic transition modeling of ebola virus vaccination in lower-and-middle-income countries.

BACKGROUND: With the increasing occurrence of infectious diseases in lower-and-middle-income countries (LMICs), emergency preparedness is essential for rapid response and mitigation. Economic evaluations of mitigation technologies and strategies have been recommended for inclusion in emergency preparedness plans. We aimed to perform an economic evaluation using dynamic transition modeling of ebola virus disease (EVD) vaccination in a hypothetical community of 1,000 persons in the Democratic Republic of Congo (DRC). METHOD: Using a modified SEIR (Susceptible, Exposed, Infectious, Recovered, with Death added [SEIR-D]) model that accounted for death and epidemiological data from an EVD outbreak in the DRC, we modeled the transmission of EVD in a hypothetical population of 1,000. With our model, we estimated the cost-effectiveness of an EVD vaccine and an EVD vaccination intervention. RESULTS: The results showed vaccinating 50% of the population at risk prevented 670 cases, 538 deaths, and 22,022 disability-adjusted life years (DALYs). The vaccine was found to be cost-effective with an incremental cost-effectiveness ratio (ICER) of $95.63 per DALY averted. We also determined the minimum required vaccination coverage for cost-effectiveness to be 40%. Sensitivity analysis showed our model to be fairly robust, assuring relatively consistent results even with variations in such input parameters as cost of screening, as well as transmission, infection, incubation, and case fatality rates. CONCLUSION: EVD vaccination in our hypothetical population was found to be cost-effective from the payer perspective. Our model presents an efficient and reliable approach for conducting economic evaluations of infectious disease interventions as part of an emergency preparedness plan.

PLAIN LANGUAGE SUMMARYInfectious diseases affect lower-and-middle-income (LMIC) countries, with their limited resources, disproportionately more. This is certainly the case for ebola virus disease (EVD), a rare, severe, and mostly fatal disease. Vaccination is now available, but whether it is cost-effective remains an open question. We evaluated its cost-effectiveness by modeling the spread of EVD in a hypothetical population of 1000 persons. Using data from an EVD outbreak in the Democratic Republic of Congo (DRC), we estimated how many of persons susceptible to infection were exposed to the virus, became infected, recovered, or died. We did so for two scenarios: vaccinating versus not vaccinating enough people to achieve herd immunity. We assumed vaccinating 50% of the people and estimated how many infections, deaths, and disability-adjusted life years (DALY; the loss of the equivalent of a year of full health) would be prevented by vaccination. Our cost-effectiveness metric was the incremental cost of preventing one DALY.The outcomes of vaccination offset the additional costs. Vaccinating 50% of the population of 1000 cost an additional $2,081,358 but prevented 670 infections, 538 deaths, and 22022 DALYs. Preventing one DALY cost $95.63. This is very cost-effective as it is less than the gross domestic product (GDP) per capita for the DRC of $556.81. Vaccination below 40% of the population was less cost-effective, was most cost-effective at the herd immunity threshold of 45.3%, beyond which there were diminishing returns. Summarized, vaccination against EVD is clinically very effective and certainly worth the additional cost.

Community-Engaged Approaches to Cervical Cancer Prevention and Control in Sub-Saharan Africa: A Scoping Review.

Background: Cervical cancer remains one of the top causes of cancer mortality among African women. Cervical cancer screening and early detection and treatment of precancer is one of the evidence-based interventions to reduce incidence and mortality. The application of community-based participatory research (CBPR) has been used in the United States to improve participation in screening and reduce cervical cancer disparities. However, it is unclear whether these engaged approaches have been used in sub-Saharan African to address disparities related to cervical cancer mortality. Objectives: Highlight community engagement in cervical cancer prevention and control in Sub-Saharan Africa (SSA), describe the community engagement efforts that are currently being used, and to describe the best practices for community engagement toward the end-goal of cervical cancer prevention and control. Methods: We searched PubMed, Embase, CINHAL, African Journals Online (AJOL), and African Index Medicus-WHO from inception until June 8, 2020. After screening 620 titles and abstracts, and reviewing 56 full-text articles according to inclusion and exclusion criteria, 9 articles met the selection criteria and were included. Relevant data variables were extracted from the included articles and a narrative synthesis was performed. Results: Between 2005 and 2019, 9 articles describing research in Ghana, Kenya, Zambia, Senegal, South Africa, and Nigeria were included. These articles described work that largely took place in rural settings predominantly among women age 15-65 years. Leveraging community networks such as community health workers, religious organizations, traditional leaders, and educational institutions increased awareness of cervical cancer. Working within existing social structures and training community members through the research effort were promising methods for addressing the disparities in cervical cancer incidence and mortality among communities. Discussion: The findings of this scoping review have contributed to the understanding of which novel approaches to community-based practices can be used to address cervical cancer disparities among SSA communities that carry a disproportionate disease burden. Community engagement in the research process, while effortful, has shown to be beneficial to researchers and to the communities that they serve, and provides valuable next steps in the effort to address cervical cancer disparities in SSA.
