RESUMEN

BACKGROUND: Despite advances in biomedical HIV prevention modalities such as pre-exposure prophylaxis to prevent the transmission of HIV, racial/ethnic and sexual/gender minority populations are disproportionately impacted by HIV epidemic. Alarming rates of HIV have persisted among Black gay and bisexual men, particularly in Southern states. METHODS: Utilizing data from the ViiV ACCELERATE! initiative, we explored the impact of As Much As I Can, an immersive theatre production, on HIV-related stigma behaviors. A self-administered post-performance survey was conducted with a cohort (n = 322) of randomly selected audience members. RESULTS: Overall, the results showed participants had a highly favorable experience, rating the performance with a mean score of 9.77/10. Respondents indicated they intended to change behaviors to promote HIV prevention education and to reduce stigma and discrimination including: (1) Say something if I hear stigmatizing language against people living with HIV (75.4%), (2) Say something if I hear anti-gay language (69.7%) and (3) Tell others about HIV prevention options (e.g., PrEP, PEP, condoms (64.1%). The findings show there is an association between HIV-related behavior intention and linkage to HIV care. Respondents who reported they were more likely to say something about HIV stigma were almost three times (O.R. 2.77; 95% C.I. 0.98-7.8) more likely to indicate they would follow up with a healthcare professional. CONCLUSIONS: This study suggests that immersive theatre is an effective method for communicating HIV prevention education and reducing HIV-related structural stigma and discrimination that increases HIV vulnerability for Black sexual minority men.

RESUMEN

Community engagement is important for reaching populations at risk for health inequities in the coronavirus disease 2019 (COVID-19) pandemic. A community-engaged risk communication intervention implemented by a community-engaged research partnership in Southeast Minnesota to address COVID-19 prevention, testing, and socioeconomic impacts has demonstrated high acceptability, feasibility, perceived efficacy, and sustainability. In this study, we describe the adaptation of the intervention by a community-academic partnership with rural African American populations in three Mississippi counties with high COVID-19 disparities. Intervention reach was assessed by the number of messages delivered by Communication Leaders to members of their social networks. Perceived scalability of the intervention was assessed by the Intervention Scalability Assessment Tool. Bidirectional communication between Communication Leaders and community members within their social networks was used by the partnership to refine messages, meet resource needs, and advise statewide decision-makers. In the first 3 months, more than 8482 individuals were reached in the three counties. The intervention was deemed to be highly scalable by partnership members. Adaptation of a community-engaged pandemic CERC intervention is feasible and scalable, and it has the potential to reduce COVID-19 inequities across heterogeneous populations. This approach may be incorporated into current and future pandemic preparedness policies for community engagement.

RESUMEN

This article examines implementational factors associated with an HIV patient navigation training intervention for health care professionals working with Black sexual minority men to improve access to and uptake of HIV prevention services among Black MSM. Utilizing qualitative analysis to better understand healthcare professionals' perceptions of the training program, we conducted a thematic content analysis based on constructs from Professional Network and Reach Model-Systems Model Approach (PNRSMA) framework. Data analysis revealed four major themes: 1) Knowledge and skill building, 2) Novel and Innovation, 3) Barriers to Implementation, and 4) Recommendations and Future Directions. Implementation factors such as appropriate facilitators, content, mode of delivery, learning strategies, and understanding structural barriers were important to training success. Participants highlighted innovation strategies such as the use of social media and interactive communication (e.g. role-playing and bi-directional communication) enhanced learning and skill-building. The expansion of training to include other affected groups such as women and bisexual individuals and increasing the duration of the training emerged as areas for improvement and effectiveness. Our analysis of an HIV patient navigation training revealed important findings to improve the implementation process to increase uptake of PrEP and other HIV prevention, care and treatment services.

RESUMEN

Despite the recommendations for COVID-19 preventive health behaviors, it continues to increase alarmingly. This study examined how media coverage, myths, political leaders, and community leaders influence the attitudes and misconceptions about COVID-19 and COVID-19 vaccination uptake in the Mississippi Delta region. This qualitative study employed focus group discussions (FDGs) with representatives from three rural counties in the Mississippi Delta. A thematic analysis approach was used for data analysis. Participants were aware of how COVID-19 is transmitted, the preventative measures that can be used to mitigate the spread of the virus, and misconceptions and beliefs that lingered in their communities. Participants were uncertain about the need for the COVID-19 vaccine in terms of perceived risks (e.g., side effects, efficacy, and safety) and its novelty. Participants also discussed a wide range of COVID-19 misinformation that resulted in distress and distrust of the vaccine and health behavior recommendations. There are varying misconceptions and beliefs about COVID-19 and COVID-19 vaccine among communities in the rural Mississippi Delta. Thus, multi-sectoral collaborations between agencies that can use risk communication frameworks to deliver accurate health information that can resolve misinformation about COVID-19 in rural communities are needed.

RESUMEN

OBJECTIVES: Adolescents and young adults represent the largest group of new human immunodeficiency virus (HIV) infections in the United States, especially in the South. We wanted to determine whether abstinence only until marriage (AOUM) sex education programs were effective in reducing HIV vulnerability among youth in Mississippi. METHODS: Using the 2015 Mississippi Youth Risk Behavior Surveillance System, we examined the effect of AOUM sex education among a sample of youth ages 12 to 18 years on 4 HIV-related sexual risk behaviors. RESULTS: Compared with youth not enrolled in AOUM sex education, we found no statistically significant differences on sexual risk behaviors. Race, age, and gender were significant risk factors in predicting sexual risk behavior. CONCLUSIONS: AOUM sex education programs are ineffective in reducing HIV vulnerability among youth in Mississippi. There is an urgent need to implement comprehensive sex education if we are to reduce the numbers of new HIV infections among youth and achieve our goals of ending the HIV epidemic by 2030.

RESUMEN

To characterize cervical cancer screening knowledge, beliefs, behaviors, and sociodemographic factors among women aged 25-45 years who access and utilize prenatal care services in Nairobi, Kenya. A descriptive cross-sectional design using a convenience sample of pregnant women receiving prenatal health services at a public and a private hospital in Nairobi, Kenya. Constructs from the Health Belief Model (HBM) guided the design, interpretation of the results, and recommendations. Data were analyzed using SPSS version 24. Bivariate analyses were conducted to examine associations between variables. There was a significant association (p=0.001) between knowledge and screening behaviors. There was no association (p=0.066) between cervical cancer beliefs (perceived susceptibility, perceived severity, perceived benefits, perceived barriers, and self-efficacy) and screening behaviors. Knowledge and beliefs influence cervical cancer screening behavior. Low cervical cancer screening uptake substantiates the need for tailoring culturally specific health behavior change communication to address misconceptions about cervical cancer screening in Kenya.

RESUMEN

The southern region of the USA is the epicenter of the HIV epidemic. HIV disproportionately affects African Americans, particularly Black men who have sex with men (Black MSM). Given the alarming rates of new infections among Black MSM, there is an urgent need for culturally competent healthcare professionals who are trained to address the unique needs and barriers to uptake and adherence to HIV prevention, care, and treatment services. Utilizing a mixed method research approach, we conducted a process evaluation of Meet Me Where I Am, a 6-month, 6-session HIV/AIDS patient navigation training program for healthcare professionals and patient navigators working in organizations that provide HIV services to residents of central Mississippi, an area with high incidence and prevalence rates of HIV. A self-administered questionnaire after each session was given to participants to assess the acceptability, quality, and translational aspects of the training program. The overall positive feedback on the MMWIA training reflects the program's acceptability and feasibility. Participants found that the training was effective in providing the necessary knowledge and skills to deliver patient-centered HIV prevention-related navigation services. A majority (67%) of participants indicated that they felt they could apply the lessons learned within their healthcare settings to improve access to HIV prevention, care, and treatment services. If we are to reduce racial and ethnic disparities in HIV/AIDS, there is a critical need for culturally appropriate training programs designed to improve the ability of healthcare professionals and health systems to deliver culturally competent HIV prevention, care, and treatment services.

RESUMEN

Background: Haitian women residing in the United States are disproportionately affected by cervical cancer. Human papillomavirus (HPV) vaccine has been licensed in the United States since 2006. Vaccination rates are less than optimal overall, and the rates are particularly low among young black women. We investigated barriers to HPV vaccination in a sample of Haitian American college women. Methods: Thirty self-identified Haitian American women, aged 17-26 years, were recruited from a large university campus in southeastern United States (n=30). They completed in-depth face-to-face interviews. The research team analyzed the transcripts using thematic analysis. Results: More than half of the participants (n=18) had not yet initiated the HPV vaccine series. Most of the unvaccinated participants stated that they had received a provider recommendation for the vaccine. Lack of provider recommendation, negative vaccine perception and attitudes, and side effect concerns constituted barriers to vaccination. Conclusions: Haitian American college women at high risk of cervical cancer have cited several barriers to HPV vaccination, with the most prominent being lack of physician recommendation. Healthcare providers should continue recommending the vaccine to college women as many of them may not have received a recommendation. When recommending the HPV vaccine, discussions should be framed with the intent to positively influence HPV vaccine perceptions and ultimately vaccine attitudes.

RESUMEN

BACKGROUND: Sulphadoxine-pyrimethamine (SP), an antifolate, was replaced by artemether-lumefantrine as the first-line malaria drug treatment in Kenya in 2004 due to the wide spread of resistance. However, SP still remains the recommended drug for intermittent preventive treatment in pregnant women and infants (IPTP/I) owing to its safety profile. This study assessed the prevalence of mutations in dihydrofolate reductase (Pfdhfr) and dihydropteroate synthase (Pfdhps) genes associated with SP resistance in samples collected in Kenya between 2008 and 2012. METHODS: Field isolates collected from Kisumu, Kisii, Kericho and Malindi district hospitals were assessed for genetic polymorphism at various loci within Pfdhfr and Pfdhps genes by sequencing. RESULTS: Among the Pfdhfr mutations, codons N51I, C59R, S108N showed highest prevalence in all the field sites at 95.5%, 84.1% and 98.6% respectively. Pfdhfr S108N prevalence was highest in Kisii at 100%. A temporal trend analysis showed steady prevalence of mutations over time except for codon Pfdhps 581 which showed an increase in mixed genotypes. Triple Pfdhfr N51I/C59R/S108N and double Pfdhps A437G/ K540E had high prevalence rates of 86.6% and 87.9% respectively. The Pfdhfr/Pfdhps quintuple, N51I/C59R/S108N/A437G/K540E mutant which has been shown to be the most clinically relevant marker for SP resistance was observed in 75.7% of the samples. CONCLUSION: SP resistance is still persistently high in western Kenya, which is likely due to fixation of key mutations in the Pfdhfr and Pfdhps genes as well as drug pressure from other antifolate drugs being used for the treatment of malaria and other infections. In addition, there is emergence and increasing prevalence of new mutations in Kenyan parasite population. Since SP is used for IPTP/I, molecular surveillance and in vitro susceptibility assays must be sustained to provide information on the emergence and spread of SP resistance.

RESUMEN

In combination with antibiotics, quinine is recommended as the second-line treatment for uncomplicated malaria, an alternative first-line treatment for severe malaria, and for treatment of malaria in the first trimester of pregnancy. Quinine has been shown to have frequent clinical failures, and yet the mechanisms of action and resistance have not been fully elucidated. However, resistance is linked to polymorphisms in multiple genes, including multidrug resistance 1 (Pfmdr1), the chloroquine resistance transporter (Pfcrt), and the sodium/hydrogen exchanger gene (Pfnhe1). Here, we investigated the association between in vitro quinine susceptibility and genetic polymorphisms in Pfmdr1codons 86 and 184, Pfcrt codon 76, and Pfnhe1 ms4760 in 88 field isolates from western Kenya. In vitro activity was assessed based on the drug concentration that inhibited 50% of parasite growth (the IC50), and parasite genetic polymorphisms were determined from DNA sequencing. Data revealed there were significant associations between polymorphism in Pfmdr1-86Y, Pfmdr1-184F, or Pfcrt-76T and quinine susceptibility (P < 0.0001 for all three associations). Eighty-two percent of parasites resistant to quinine carried mutant alleles at these codons (Pfmdr1-86Y, Pfmdr1-184F, and Pfcrt-76T), whereas 74% of parasites susceptible to quinine carried the wild-type allele (Pfmdr1-N86, Pfmdr1-Y184, and Pfcrt-K76, respectively). In addition, quinine IC50 values for parasites with Pfnhe1 ms4760 3 DNNND repeats were significantly higher than for those with 1 or 2 repeats (P = 0.033 and P = 0.0043, respectively). Clinical efficacy studies are now required to confirm the validity of these markers and the importance of parasite genetic background.

RESUMEN

Single Nucleotide Polymorphisms (SNPs) in the Pfmdr1, and Pfcrt, genes of Plasmodium falciparum may confer resistance to a number of anti-malaria drugs. Pfmdr1 86Y and haplotypes at Pfcrt 72-76 have been linked to chloroquine (CQ) as well as amodiaquine (AQ) resistance. mefloquine (MQ) and lumefantrine (LU) sensitivities are linked to Pfmdr1 86Y. Additionally, Pfcrt K76 allele carrying parasites have shown tolerance to LU. We investigated the association between Pfmdr1 86/Pfcrt 72-76 and P. falciparum resistance to CQ, AQ, MQ and LU using field samples collected during 2008-2011 from malaria endemic sites in western Kenya. Genomic DNA from these samples was genotyped to examine SNPs and haplotypes in Pfmdr1 and Pfcrt respectively. Additionally, immediate ex vivo and in vitro drug sensitivity profiles were assessed using the malaria SYBR Green I fluorescence-based assay. We observed a rapid but steady percent increase in wild-type parasites with regard to both Pfmdr1 and Pfcrt between 2008 and 2011 (p<0.0001). Equally, a significant reciprocate decrease in AQ and CQ median IC50 values occurred (p<0.0001) during the same period. Thus, the data in this study point to a significantly rapid change in parasite response to AQ and CQ in the study period. This may be due to releasing of drug pressure on the parasite from reduced use of AQ in the face of increased Artemisinin (ART) Combination Therapy (ACT) administration following the intervention of the Global Fund in 2008. LU has been shown to select for 76K genotypes, thus the observed increase in 76K genotypes coupled with significant cross resistance between LU and MQ, may herald emergence of tolerance against both drugs in future.

RESUMEN

In vitro drug sensitivity and molecular analyses of Plasmodium falciparum track drug resistance. DNA-binding fluorescent dyes like SYBR Green I may allow field laboratories, proximal to P. falciparum collection sites, to conduct drug assays. In 2007-2008, we assayed 121 P. falciparum field isolates from western Kenya for 50% inhibitory concentrations (IC(50)) against 6 antimalarial drugs using a SYBR Green I in vitro assay: 91 immediate ex vivo (IEV) and 30 culture-adapted, along with P. falciparum reference clones D6 (chloroquine [CQ] sensitive) and W2 (CQ resistant). We also assessed P. falciparum mdr1 (Pfmdr1) copy number and single nucleotide polymorphisms (SNPs) at four codons. The IC(50)s for IEV and culture-adapted P. falciparum isolates were similar, and approximated historical IC(50)s. For Pfmdr1, mean copy number was 1, with SNPs common at codons 86 and 184. The SYBR Green I assay adapted well to our field-based laboratory, for both IEV and culture-adapted P. falciparum, warranting continued use.
