Self-reported COVID-19 infection and implications for mental health and food insecurity among American college students.

While the COVID-19 pandemic affected mental health and increased food insecurity across the general population, less is known about the virus's impact on college students. A fall 2020 survey of more than 100,000 students at 202 colleges and universities in 42 states reveals sociodemographic variation in self-reported infections, as well as associations between self-reported infection and food insecurity and mental health. We find that 7% of students self-reported a COVID-19 infection, with sizable differences by race/ethnicity, socioeconomic status, parenting status, and student athlete status. Students who self-reported COVID-19 infections were more likely to experience food insecurity, anxiety, and depression. Implications for higher education institutions, policy makers, and students are discussed.

Pirfenidone ameliorates ANIT-induced cholestatic liver injury via modulation of FXR, NF-кB/TNF-α, and Wnt/GSK-3ß/ß-catenin signaling pathways.

Cholestasis is a hepatobiliary disorder characterized by the excessive accumulation of toxic bile acids in hepatocytes, leading to cholestatic liver injury (CLI) through multiple pathogenic inflammatory pathways. Currently, there are limited therapeutic options for the management of cholestasis and associated CLI; therefore, new options are urgently needed. Pirfenidone (PF), an oral bioavailable pyridone analog, is used for the treatment of idiopathic pulmonary fibrosis. PF has recently demonstrated diverse potential therapeutic activities against different pathologies. Accordingly, the present study adopted the α-naphthyl isothiocyanate (ANIT)-induced CLI model in mice to explore the potential protective impact of PF and investigate the underlying mechanisms of action. PF intervention markedly reduced the serum levels of ALT, AST, LDH, total bilirubin, and total bile acids, which was accompanied by a remarkable amelioration of histopathological lesions induced by ANIT. PF also protected the mice against ANIT-induced redox imbalance in the liver, represented by reduced MDA levels and elevated GSH and SOD activities. Mechanistically, PF inhibited ANIT-induced downregulated expressions of the farnesoid X receptor (FXR), as well as the bile salt export pump (BSEP) and the multidrug resistance-associated protein 2 (MRP2) bile acid efflux channels. PF further repressed ANIT-induced NF-κB activation and TNF-α and IL-6 production. These beneficial effects were associated with its ability to dose-dependently inhibit Wnt/GSK-3ß/ß-catenin/cyclin D1 signaling. Collectively, PF protects against ANIT-induced CLI in mice, demonstrating powerful antioxidant and anti-inflammatory activities as well as an ability to oppose BA homeostasis disorder. These protective effects are primarily mediated by modulating the interplay between FXR, NF-κB/TNF-α/IL-6, and Wnt/ß-catenin signaling pathways.

Exploring the potential of Aspergillus wentii: secondary metabolites and biological properties.

Fungi are of considerable importance due to their capacity to biosynthesize various secondary metabolites with bioactive properties that draw high attention in new drug discovery with beneficial uses for improving human well-being and life quality. Aspergillus genus members are widespread and cosmopolitan species with varying economic significance in the fields of industry, medicine, and agriculture. Its species are renowned for their biosynthesis of secondary metabolites, characterized by both potent biological activity and structural novelty, making them a substantial reservoir for the development of new pharmaceuticals. The current work aimed at focusing on one species of this genus, Aspergillus wentii Wehmer, including its reported secondary metabolites in the period from 1951 to November 2023. A total of 97 compounds, including nitro-compounds, terpenoids, anthraquinones, xanthones, benzamides, and glucans. A summary of their bioactivities, as well as their biosynthesis was highlighted. Additionally, the reported applications of this fungus and its enzymes have been discussed. This review offers a useful reference that can direct future research into this fungus and its active metabolites, as well as their possible pharmacological and biotechnological applications.

The current state of complex systems research on socioeconomic inequalities in health and health behavior-a systematic scoping review.

BACKGROUND: Interest in applying a complex systems approach to understanding socioeconomic inequalities in health is growing, but an overview of existing research on this topic is lacking. In this systematic scoping review, we summarize the current state of the literature, identify shared drivers of multiple health and health behavior outcomes, and highlight areas ripe for future research. METHODS: SCOPUS, Web of Science, and PubMed databases were searched in April 2023 for peer-reviewed, English-language studies in high-income OECD countries containing a conceptual systems model or simulation model of socioeconomic inequalities in health or health behavior in the adult general population. Two independent reviewers screened abstracts and full texts. Data on study aim, type of model, all model elements, and all relationships were extracted. Model elements were categorized based on the Commission on Social Determinants of Health framework, and relationships between grouped elements were visualized in a summary conceptual systems map. RESULTS: A total of 42 publications were included; 18 only contained a simulation model, 20 only contained a conceptual model, and 4 contained both types of models. General health outcomes (e.g., health status, well-being) were modeled more often than specific outcomes like obesity. Dietary behavior and physical activity were by far the most commonly modeled health behaviors. Intermediary determinants of health (e.g., material circumstances, social cohesion) were included in nearly all models, whereas structural determinants (e.g., policies, societal values) were included in about a third of models. Using the summary conceptual systems map, we identified 15 shared drivers of socioeconomic inequalities in multiple health and health behavior outcomes. CONCLUSIONS: The interconnectedness of socioeconomic position, multiple health and health behavior outcomes, and determinants of socioeconomic inequalities in health is clear from this review. Factors central to the complex system as it is currently understood in the literature (e.g., financial strain) may be both efficient and effective policy levers, and factors less well represented in the literature (e.g., sleep, structural determinants) may warrant more research. Our systematic, comprehensive synthesis of the literature may serve as a basis for, among other things, a complex systems framework for socioeconomic inequalities in health.

Exploring the Comparability Between EQ-5D and the EQ Health and Wellbeing in the General Australian Population.

OBJECTIVES: The EQ Health and Wellbeing (EQ-HWB) is a novel measure that conceptually overlaps with the 5-level EQ-5D (EQ-5D-5L) while capturing broader dimensions of health and well-being. This study aimed to explore the extent to which the EQ-HWB and EQ-5D-5L capture overlapping or complementary constructs and to explore the discriminative ability of the EQ-HWB Short version (EQ-HWB-S) as a multiattribute utility instrument in the Australian setting. METHODS: A secondary analysis of data from a nationally representative cross-sectional survey of 2002 Australian adults was performed. The survey included socioeconomic questions and health characteristics and the EQ-HWB and EQ-5D-5L instruments. Convergent and known-group validity were evaluated through Spearman rank correlation and multivariable regression analyses, respectively. An exploratory factor analysis was also performed to explore the underlying constructs of the 2 measures. RESULTS: Correlation coefficients varied from moderate to strong (rs ≥ 0.40) between the EQ-5D-5L and the corresponding EQ-HWB dimensions (all P < .001). Based on the exploratory factor analysis, both instruments measure similar underlying constructs, with the EQ-HWB capturing broader aspects of well-being. The known-group analysis demonstrated the relative discriminative ability of the EQ-HWB-S in capturing broader aspects of health and well-being. CONCLUSIONS: The EQ-HWB was at least moderately correlated with the EQ-5D-5L in overlapping domains/dimensions and demonstrated greater sensitivity in participants with mental health problems versus the EQ-5D-5L. Our findings support future research exploring the value of the EQ-HWB-S as a multiattribute utility instrument for the general Australian population.

The Measurement Properties of the EQ-HWB and the EQ-HWB-S in Italian Population: A Comparative Study With EQ-5D-5L.

OBJECTIVES: The EQ Health and Well-being, EQ-HWB (25-item) and the EQ-HWB-S (9-item), are new generic measures of health and well-being. The purpose of this study was to examine the measurement properties of the EQ-HWB and EQ-HWB-S measures in relation to the EQ-5D-5L among the Italian general population. METHODS: A cross-sectional survey was conducted from October 2020 to February 2021, followed by secondary analysis of collected data from Italian adults. This analysis included response pattern distributions, correlation strength, and known-group comparison. Known-group comparison was assessed using effect sizes (ES) across health conditions, caregiver status, and social care usage. The EQ-HWB-S index-based score was based on the UK pilot value set, whereas the Italian value set was used for scoring the EQ-5D-5L index. RESULTS: Out of the 1182 participants, 461 reported having a chronic condition, 185 identified as caregivers, and 42 were social care users. EQ-HWB items (7.5%) showed fewer ceiling effects than EQ-5D-5L items (34.7%). Strong correlations (rs > 0.5) were found between overlapping EQ-HWB and EQ-5D-5L items. EQ-HWB-S and EQ-5D-5L index scores demonstrated similar discrimination based on symptomatic chronic conditions (ES d = 0.68 vs d = 0.71), but EQ-HWB-S had slightly higher ES for social care users (ES d = 0.84 vs d = 0.74). CONCLUSIONS: Initial evidence supports the validity of EQ-HWB/EQ-HWB-S because outcome measures in the Italian population. EQ-HWB-S performed comparably to EQ-5D-5L among patients and was better in differentiating social care users. A slight decrease in discriminative properties for caregivers was observed when transitioning from EQ-HWB to EQ-HWB-S.

Psychometric Performance of the EQ Health and Wellbeing Short in a United Kingdom Population Sample.

OBJECTIVES: This study assessed the psychometric performance and construct validity of the EQ Health and Wellbeing Short (EQ-HWB-S), using a validated measure, the EQ-5D-5L, as a comparator. METHODS: The experimental version of the EQ-HWB-S was compared with the EQ-5D-5L to assess the psychometric performance of the measures. Data were drawn from the valuation stages of the Extending the Quality-Adjusted Life-Year project (UK general population, n = 429) and the EQ-5D-5L UK valuation pilot study (UK general population, n = 248). Construct validity was assessed based on convergent validity, using Spearman correlations and Pearson correlations. Known-group validity was assessed by estimating effect sizes to assess the ability of the EQ-HWB-S and EQ-5D-5L to discriminate between known groups based on "healthy" status, presence of a long-term condition, health and life satisfaction, age, and employment status. The degree of agreement in utility values across instruments was also evaluated using Bland-Altman plots. RESULTS: Strong associations (rs ≥ 0.5, P < .001) were found between conceptually overlapping dimensions and the utility scores of the EQ-HWB-S and EQ-5D-5L. The instruments performed comparably in discriminating between known groups including healthy versus unhealthy groups (based on the visual analog scale ≥ 80), long-term condition (vs no long-term condition), and above versus below average health and life satisfaction and employed (vs unemployed and long-term sick). CONCLUSIONS: The EQ-HWB-S performs favorably with utility values successfully discriminating between groups in which differences are expected. Convergence between the EQ-HWB-S and EQ-5D-5L is evident, especially between conceptually overlapping dimensions.

How Well Does the EQ-5D-Y-5L Describe Children With Intellectual Disability?: "There's a Lot More to My Child Than That She Can't Wash or Dress Herself."

OBJECTIVES: The EQ-5D-5L is a generic health utility instrument for measuring health-related quality of life (HRQoL), with self-report and proxy report versions for children (EQ-5D-Y-5L). Children with intellectual disability (ID) are a heterogeneous population whose impairments and comorbidities place them at risk of poor HRQoL. This study aimed to describe the content validity and suitability for children with ID of a proxy report version of the EQ-5D-Y-5L as seen by their caregivers. METHODS: A proxy report EQ-5D-Y-5L was administered to caregivers of children with ID. Using cognitive think-aloud interviewing, participants were encouraged to provide the reasoning for their choices, assess the questions' relevance, comprehensibility, and comprehensiveness, and comment on the tool's strengths and weaknesses. Qualitative content analysis used both directed (deductive) and conventional (inductive) methods. RESULTS: There were 28 interviews with 30 caregivers of children with ID (aged 8-22 years, 17 boys, with autism spectrum disorder, cerebral palsy, Down syndrome, and rare genetic disorders). The EQ-5D-Y-5L was considered clear, concise, and largely relevant, but insufficiently comprehensive for this population. Interviewees sought clarification of the definition of HRQoL, whether it included unchanging impairments (vs fluctuating health states), and what basis of comparison to use (child or peer). Many interviewees suggested inclusion of questions for other domains, including communication and social engagement, equipment and human supports required, and a wider range of mental health questions. CONCLUSIONS: The study suggests that further work is required to ensure accurate responses to the EQ-5D-Y-5L from caregivers of children with ID and to describe these children adequately.

Living through a pandemic: depression and anxiety experienced by youth living with HIV in South Africa.

Youth living with HIV (YLHIV) face significant psychosocial challenges and are at increasedrisk of developing depression and anxiety. This study aims to invesBgate symptoms ofdepression, anxiety and associaBons with psychosocial factors in YLHIV during the first andthird waves of the COVID-19 pandemic. This longitudinal study enrolled 135 YLHIV (ages 12-21) in Cape Town, South Africa. Measures administered telephonically included theCoRonavIruS Health Impact Survey (CRISIS quesBonnaire), Center for Epidemiologic StudiesDepression Scale (CES-D), Beck Anxiety Inventory and Beck Youth Inventory. During the firstwave of COVID-19, 7.5% and 8.0% of YLHIV were depressed (<18 and ≥18 years,respecBvely), and 10% and 4% of parBcipants were anxious (<18 and ≥18 years). During thethird wave, 8.9% and 40.6% of YLHIV were depressed (<18 and ≥18 years), and 13.3% and12.5% (<18 and ≥18 years) were anxious. Depression and anxiety were measured using cutoffscores provided by clinical measures. Symptoms of depression and anxiety in YLHIVescalated over the course of the COVID-19 pandemic. Socio-economic factors, substanceuse, disrupted support and stability concerns were associated with depression and anxiety.These data highlight the increasing need of mental health support and social intervenBonsfor YLHIV in post-pandemic South Africa.

Stigma, serostatus disclosure, coping strategies, and the role of social capital resources among HIV care-nonadherent MSM in Russia: a qualitative analysis.

The HIV epidemic continues to expand in Russia, with suboptimal levels of care uptake. This qualitative study aimed to characterize social capital resources and lived stigma experiences, coping, and disclosure among care-nonadherent men who have sex with men (MSM) living with HIV in Russia. Twenty-five HIV-positive MSM - recruited online - completed in-depth interviews over Zoom, with data analyzed using MAXQDA software. Stigma was more likely to be encountered in interactions with persons with whom social ties were weaker such as medical providers and relatives, particularly males. Close friends - often other HIV-positive MSM and female relatives - were the most supportive and least stigmatizing. Similar persons were most often considered for HIV serostatus disclosure. Coping strategies to reduce the impact of stigma included ignoring stigmatizing experiences, seeking support from members of one's social circle, minimizing contact with stigmatizing persons, seeking new relationships with persons who are also HIV-positive, proactively reducing stigma through involvement in advocacy roles, and correcting myths and educating others about HIV infection. These findings underscore the need for interventions to assist HIV-positive MSM in building accepting social capital resources to reduce the impact of stigma and to build support within their social networks, often with other HIV-positive MSM.

Prevalence of mental distress and factors associated with symptoms of major depression among people living with HIV in Norway.

For people living with HIV (PLHIV) who can access lifesaving treatment, HIV has become a chronic lifelong condition; however, PLHIV have more mental and somatic comorbidities than their HIV-negative peers. In this cross-sectional study, we assessed the prevalence of mental distress and identified factors associated with major depression among 244 well-treated PLHIV residing in Norway. Participants completed validated questionnaires covering mental and somatic health. The prevalence of mental distress, defined as a score on the Hopkins Symptom Check List-25 >1.75, was 32%, and that of symptoms of major depression, defined as a score on the Beck Depression Inventory-II ≥20, was 15%. The factors associated with major depressive symptoms identified using logistic regression were risk of drug abuse (adjusted odds ratio (AOR) 15.1, 95% confidence interval (CI) 3.28, 69.3), fatigue (AOR 12.5, 95% CI 3.90, 40.0), trouble sleeping (AOR 7.90, 95% CI 2.85, 21.9), African origin (AOR 3.90, 95% CI 1.28, 11.9), low education (AOR 3.31, 95% CI 1.18, 9.30), and non-disclosure (AOR 3.22, 95% CI 1.04, 10.0). Our findings indicate that the prevalence rates of mental distress and major depressive symptoms are higher among well-treated PLHIV residing in Norway than in the general population. These conditions are under-diagnosed and under-treated, and increased awareness is needed.

Association between maternal HIV status and postpartum depressive symptoms in Botswana.

Few studies have evaluated postpartum depression (PPD) in women living with HIV (WLHIV) in Botswana, a high prevalence HIV setting. The Edinburgh Postnatal Depression Scale (EPDS) was used to evaluate PPD symptoms in WLHIV (n = 300) and women who are HIV-uninfected (n = 131) in the Tshilo Dikotla study, an observational cohort study with a nested randomized trial. The EPDS was administered at 2, 6, and 12 months postpartum. We assessed the association of (1) HIV infection and (2) antiretroviral therapy (ART) with odds of PPD symptoms (EPDS ≥ 10 or thoughts of self-harm) in the first year postpartum using generalized estimating equations. Of WLHIV, 24 (8.00%) had PPD symptoms at one or more follow-up time points, compared to 9 (6.9%) women who were HIV-seronegative. There was no association between HIV status and PPD symptoms (adjusted odds ratio [aOR]:1.69, 95% confidence interval [CI]: 0.73-3.93, p = 0.225); however, WLHIV on efavirenz-based ART regimens had higher odds of experiencing PPD symptoms compared to dolutegravir-based ART (aOR:3.05, 95% CI:1.16-8.03, p = 0.024).

Modeling the HIV epidemic in MSM in Cyprus: reaching only the 95-95-95 cascade of care targets fails to reduce HIV incidence by 90% in 2030.

National responses should be improved and accelerated to meet the target of ending the Acquired ImmunoDeficiency Syndrome (AIDS) epidemic by 2030. In the Republic of Cyprus, Men who have Sex with Men (MSM) are disproportionately affected by Human Immunodeficiency Virus (HIV), accounting approximately for half of all annual HIV diagnoses. This study assesses the evolution of HIV incidence in MSM in Cyprus until 2030 using a model calibrated to Cypriot epidemiological data. Four scenarios were examined: status quo, two scenarios focusing on introducing Pre-Exposure Prophylaxis (PrEP), and a 90% HIV incidence reduction scenario. Reaching only the 95-95-95 HIV cascade of care targets among MSM would reduce HIV incidence by 48.6% by 2030 compared to 2015. Initiating a PrEP intervention only for high risk MSM would cause a modest further reduction in HIV incidence. To meet the 90% reduction target, PrEP should be expanded to both high and medium risk MSM and, after 2025, behavioral interventions should be implemented so as high-risk MSM gradually move to the medium-risk category. Cyprus will not reach the HIV incidence reduction target by 2030 unless PrEP is gradually promoted and delivered to all high and medium risk MSM along with awareness and behavioral interventions.

Acceptability, facilitators, and barriers to a hypothetical HIV vaccine in the pre-exposure prophylaxis era.

Little is known about the pre-implementation context for a preventive HIV vaccine. We conducted interviews of individuals in Philadelphia recruited at Penn clinics and community-based organizations serving LGBTQ-identifying persons of color who 1) were cisgender men who had sex with men, or were transgender-identified, 2) had a sexually transmitted infection in the last 12 months, or sex with multiple partners within the last two weeks. We assessed acceptability, facilitators, and barriers to a hypothetical HIV vaccine using an integrated analysis approach. We interviewed 30 individuals between 2/2023-9/2023. Participants were supportive of an HIV vaccine and reported that they would strongly consider receiving one if one became available. Participants contextualized a hypothetical vaccine with the current HIV prevention context, primarily pre-exposure prophylaxis (PrEP), indicating that they would evaluate any future vaccine in comparison to their experience within the PrEP landscape.Reported facilitators for a hypothetical HIV vaccine included vaccine access, knowledge, and understanding; their risk for HIV exposure; and perceived benefits of the vaccine. Barriers included lack of understanding of the purpose of a vaccine, stigma surrounding HIV and sexual practices that may surface towards people who seek vaccination, and potential issues with effectiveness, side effects, or lack of availability.

A network analysis of positive psychosocial factors and indication of suboptimal HIV care outcomes among Black women living with HIV.

Black women living with HIV (BWLWH) face barriers that impact health outcomes. However, positive psychosocial indicators may influence HIV care outcomes. Among this cross-sectional study of 119 BWLWH, a network analysis was utilized to examine relationships between positive psychosocial factors and HIV-related health outcomes. A preliminary polychoric analysis was conducted to examine correlations between the variables, and the network analyzed connections between resilience, self-efficacy, self-esteem, perceived social support, religious coping, post-traumatic growth, and an indicator variable for suboptimal HIV care outcomes (low medication adherence, detectable viral load, and missed HIV-related health visits) and determined the centrality measures within the network. Seven significant associations were found among the factors: self-efficacy and self-esteem, post-traumatic growth and resilience, post-traumatic growth and self-efficacy, post-traumatic growth and religious coping, perceived social support and resilience, self-esteem and resilience, self-esteem and perceived social support (bootstrapped 95% CI did not contain zero). Self-efficacy was the strongest indicator associated with the other factors. Although not statistically significant, the indicator for suboptimal HIV care outcomes was negatively associated with perceived social support and religious coping. Future interventions incorporating self-efficacy may be beneficial to the overall well-being of Black women.

HIV symptom severity and associated factors among young people with HIV in Ghana.

ABSTRACTAdolescents and young adults (young people) with HIV (YPWH) often struggle with treatment self-management. Many have symptoms due to HIV disease, medication side-effects, or comorbid conditions. Our study investigated the severity of HIV-related symptoms among YPWH aged 18-24 with detectable viral loads from an HIV clinic in Ghana (N = 60) and potential correlates of severity across a range of factors. Results indicated that YPWH currently experienced, on average, 13 symptoms (SD = 12.33). Six of the 10 most common symptoms were from two domains: fatigue and psychological. The most common symptoms were headaches (62%), weakness (53%), and fear/worries (52%). No differences were observed in number or severity of symptoms between youth based on HIV transmission status. Bivariate correlates of symptom severity were found with six that remained significant or approached significance in a multivariate model predicting severity: living with a parent/guardian, higher perceived access to HIV care, and higher treatment readiness were associated with lower severity while greater travel time to the HIV clinic, psychological distress, and more missed clinic appointments were associated with higher severity. Our findings suggest that interventions to address symptoms among YPWH should be multilevel and include strategies (e.g., telehealth, home care) to increase access to care.

Spatial analysis of HIV detection rates among Brazilian young men, 2007-2021.

The main goal of this study was to spatially analyze the HIV epidemic scenario in young men in Brazil, 2007-2021. We used secondary data obtained from the Brazilian Information System for Notifiable Diseases. Individuals aged 15-29 years with permanent residence in Brazil who were diagnosed with HIV during the study period were included in the analysis. Municipality HIV age-adjusted detection rates were analyzed through spatial distribution, autocorrelation, and spatiotemporal risk analyses. During the study period, 108,392 HIV cases were reported in young Brazilian men. The HIV epidemic increased territorially in the northern, northeastern, midwestern, and southeastern regions but decreased in the southern region. Although the number of clusters comprising municipalities with high HIV detection rates (hotspots) decreased, new ones appeared, expanded, or stopped changing size. Hotspots and spatio-temporal risk zones (spatial areas with increased HIV detection in a specific period) comprised economically developed municipalities with high demographic density surrounded by less developed municipalities. The period of the spatiotemporal risk zones was between 2008 and 2021. Our study showed that HIV detection rates continue to increase among young Brazilian men, and health authorities should reinforce efforts mainly in capitals and surrounded municipalities in the north, northeast, southeast, and midwest regions.

Perceptions of bias in HIV prevention services, happiness with social support, and anticipated PrEP stigma among Black and Latine/x sexual and gender diverse individuals.

Although pre-exposure prophylaxis (PrEP) is a highly effective preventive treatment for HIV, anticipated PrEP stigma can hinder uptake. Perceptions of bias in HIV prevention and evaluations (e.g., happiness) tied to social support among Black and Latine/x sexual and gender diverse (SGD) individuals could be important correlates of anticipated PrEP stigma. To further this line of inquiry, a national sample of 872 Black and Latine/x SGD individuals who had and had never taken PrEP (Mage = 25.1, SD = 2.8) reported how they perceived HIV prevention and how happy they were with their social support. Multivariable linear regressions revealed that greater perceptions of bias in HIV prevention services were associated with higher anticipated PrEP stigma among Black and Latine/x SGD individuals who have never taken PrEP. Greater happiness with friend support was associated with lower PrEP stigma, whereas greater happiness with family support was associated with higher PrEP stigma among individuals who have taken PrEP. Findings highlight the need for PrEP and HIV interventions to address the intersectional stigma attached to prevention and for researchers to understand how evaluations of social support may contribute to stigma among Black and Latine/x SGD individuals.

Prevalence and risk factors of detectable HIV viral load among pregnant women with HIV infection seeking antenatal care in Southern Malawi.

We evaluated detectable viral load (VL) in pregnant women established on antiretroviral therapy (ART) for at least 6 months before conception and those self-reported as ART naïve at first antenatal care (ANC) at two government clinics in Southern Malawi. We used logistic regression to identify the predictors of detectable viral load (VL), defined as any measure greater than 400 copies/ml. Of 816 women, 67.9% were established on ART and 32.1% self-reported as ART naïve. Among women established on ART, 10.8% had detectable VL and 9.9% had VL >1000 copies/ml (WHO criteria for virological failure). In adjusted analysis, among women established on ART, virological failure was associated with younger age (p = .02), "being single/widowed" (p = 0.001) and no previous deliveries (p = .05). One fifth of women who reported to be ART-naive were found to have an undetectable VL at first ANC. None of the demographic factors could significantly differentiate those with high versus low VL in the ART-naïve sub-sample. In this cohort, approximately 90% of women who had initiated ART prior to conception had an undetectable VL at first ANC. This demonstrates good success of the ART program but identifies high risk populations that require additional support.

Unexpected CD4 decay, hidden adherence gaps, resilience, and the need for long-acting therapy in a single HIV outpatients' cohort.

This single-centre, single-cohort study examines hidden non-adherence to antiretroviral therapy in a setting of persistent optimal viral suppression but concordant absolute and percent CD4 decay by >10% from the previous test. After the finding of important drug holidays in two virologically suppressed patients, between January 2021 and January 2022 all PLWH who fulfilled CD4 decay criteria were asked for how long therapy was interrupted, how many days before re-testing CD4 and HIV RNA was it resumed and the reason for interruption. Of 668 HIV-infected subjects, 61 fulfilled the pre-specified criteria for significant CD4 decay and 15 (2.25% of the total, 25% of the CD4 decay group) admitted long-lasting treatment interruptions, compensated by treatment resumption before the subsequent testing. Eleven treatment interruptions exceeded 28 days, and none was shorter than 15 days. CD4 recovery was worse at 6 months in non-adherent subjects (-0.5 vs + 16/mmc, p < 0.0001) and in non adherence vs immune decay time-related with COVID-19 (0 vs + 22/mmc, p < 0.0001). Reasons for interrupting treatment were travel, psychological, poverty-related, addiction and sentimental sphere problems. Long-acting regimens, with stringent control of precision in timely administration, may protect PLWH from damaging their health status and possibly transmit HIV.
