Virological outcomes of antiretroviral therapy and its determinants among HIV patients in Ethiopia: Implications for achieving the 95–95–95 target
Background Despite significant advancements in HIV treatment, virological outcomes remain a critical issue. Ethiopia did not meet the 90:90:90 targets set for 2020, which aimed for 90% of people on antiretroviral therapy to achieve viral suppression. As the country shifts its focus toward the 95:95:95 targets for 2030—seeking to achieve 95% viral suppression among those on ART—it is crucial to deepen our understanding of viral suppression and the factors that influence it. Methods Virological suppression was examined among 410 HIV-positive individuals on ART using the EPHIA survey. The survey employed a two-stage, stratified sampling design across urban areas in nine regions and two city administrations. Data analysis was conducted with STATA version 18, and multicollinearity was assessed using variance inflation factors. A logistic regression model identified significant determinants of viral suppression, with variables having a p-value of ≤0.05 considered statistically significant in the multivariable analysis. Results The findings revealed that 364 participants (88.78%) achieved viral suppression. Key determinants of virological outcomes included a higher wealth level (AOR = 2.67, 95% CI: 1.15–6.22), the presence of active TB (AOR = 0.27, 95% CI: 0.14–0.57), hepatitis B virus (AOR = 0.20, 95% CI: 0.10–0.31), and the utilization of HIV support group care (AOR = 3.14, 95% CI: 1.35–6.30). Conclusion Viral suppression among HIV patients is 88.78%, which even falls short of the WHO’s 90% target for 2020, indicating the substantial work required to achieve 95% by 2030. To improve virological outcomes, it is crucial to increase support for low-income patients, enhance management of co-infections like TB and hepatitis B, and expand access to HIV support groups for better adherence and care.
Exploring the causal impact of body mass index on metabolic biomarkers and cholelithiasis risk: a Mendelian randomization analysis
AbstractObesity is a well-established risk factor for various diseases, but the mechanisms through which it influences disease development remain unclear. Using Mendelian randomization (MR) analysis, we examined the causal relationship between BMI, 249 metabolic traits, and cholelithiasis. BMI data were obtained from four sources, and cholelithiasis data were from two distinct datasets. We analyzed the direct effect of BMI on cholelithiasis and identified key metabolic mediators. BMI was found to be positively associated with the risk of cholelithiasis across all datasets analyzed. A total of 176 metabolites were identified to be significantly associated with BMI, including amino acids, cholesterol esters, free cholesterol, triglycerides, and phospholipids. Among these, 49 metabolites were identified as mediators in the BMI-cholelithiasis relationship. Specifically, fatty acid levels, cholesteryl esters, phospholipids, triglycerides, and free cholesterol were key mediators in this relationship, with mediation proportions ranging from − 2.38–7.14%. This study provides robust evidence that BMI significantly impacts metabolic biomarkers, which in turn affect the risk of cholelithiasis. These findings highlight the importance of managing BMI to mitigate metabolic dysfunction and reduce the risk of gallstone formation. Future research should explore the specific metabolic pathways involved to identify potential therapeutic targets.
Enhancing betalains production and antioxidant activity in Celosia argentea cell suspension cultures using biotic and abiotic elicitors
AbstractCelosia argentea is a plant known for producing bioactive compounds, including betalains, which possess various biological and pharmaceutical properties. This study aimed to investigate the effect of biotic and abiotic elicitors on betalains production and their antioxidant activity in cell suspension cultures of C. argentea. Various concentrations of chitosan, yeast extract, salicylic acid, methyl jasmonate, copper sulfate (CuSO4), and cobalt chloride (CoCl2) were evaluated. The results revealed that chitosan, salicylic acid, methyl jasmonate, and CuSO4 significantly improved betalains production in the cell suspension cultures. Among these elicitors, chitosan at 5.0 mg/L and CuSO4 at 6.4 µM were the most effective in enhancing betalains production, yielding the highest concentrations of 4.65 and 4.99 mg/g dry weight, respectively. Notably, the betalains derived from the elicitor-treated cultures exhibited greater antioxidant activity compared to the control. These findings suggest that chitosan and CuSO4 are promising elicitors for sustainable in vitro production of betalains from C. argentea cell suspension cultures on a commercial scale, owing to their ability to enhance betalains production and antioxidant activity.

A systematic review to identify research gaps in studies modeling MenB vaccinations against Neisseria infections
The genus Neisseria includes two major human pathogens: N. meningitidis causing bacterial meningitis/septicemia and N. gonorrhoeae causing gonorrhoea. Mathematical models have been used to simulate their transmission and control strategies, and the recent observation of a meningococcal B (MenB) vaccine being partially effective against gonorrhoea has led to an increased modeling interest. Here we conducted a systematic review of the literature, focusing on studies that model vaccination strategies with MenB vaccines against Neisseria incidence and antimicrobial resistance. Using journal, preprint, and grey literature repositories, we identified 52 studies that we reviewed for validity, model approaches and assumptions. Most studies showed a good quality of evidence, and the variety of approaches along with their different modeling angles, was assuring especially for gonorrhoea studies. We identified options for future research, including the combination of both meningococcal and gonococcal infections in studies to have better estimates for vaccine benefits, and the spill over of gonorrhoea infections from the heterosexual to the MSM community and vice versa. Cost-effectiveness studies looking at at-risk and the wider populations can then be used to inform vaccine policies on gonorrhoea, as they have for meningococcal disease.

Barriers and facilitators to implementing comprehensive sex education in Texas public schools: A qualitative study
Introduction In Texas, the adolescent birth rate is higher than the national average and STIs have steadily increased over the last decade. Sex education is not mandated in Texas and the majority of public schools provide an abstinence-based sex education. Comprehensive sexuality education (CSE) programs are widely endorsed by national and global health organizations and research has shown that they are more effective in reducing poor sexual health outcomes than abstinence-based programs. The purpose of this study is to identify barriers and facilitators to implementing CSE at local and state levels in Texas. Methods Qualitative study design consisting of ten semi-structured interviews with eleven key informants (n = 11) conducted in 2021. Results Three barriers- ideological opposition to CSE, discrimination against LGBTQ+ people, myths and misconceptions about CSE- and two facilitators- champions, collaboration with community stakeholders- to implementing CSE policy were identified. Conclusion Study findings provide insight into the opposition faced by sex education advocates, which often stems from myths and misperceptions of CSE content and the stigmatization of sexual and gender minoritized groups. Parents, youth, medical professionals, and academic researchers are instrumental in dispelling sex education myths and misperceptions and engaging with community stakeholders.
