Understanding HIV/AIDS dynamics: insights from CD4+T cells, antiretroviral treatment, and country-specific analysis.

In this article, we present a mathematical model for human immunodeficiency virus (HIV)/Acquired immune deficiency syndrome (AIDS), taking into account the number of CD4+T cells and antiretroviral treatment. This model is developed based on the susceptible, infected, treated, AIDS (SITA) framework, wherein the infected and treated compartments are divided based on the number of CD4+T cells. Additionally, we consider the possibility of treatment failure, which can exacerbate the condition of the treated individual. Initially, we analyze a simplified HIV/AIDS model without differentiation between the infected and treated classes. Our findings reveal that the global stability of the HIV/AIDS-free equilibrium point is contingent upon the basic reproduction number being less than one. Furthermore, a bifurcation analysis demonstrates that our simplified model consistently exhibits a transcritical bifurcation at a reproduction number equal to one. In the complete model, we elucidate how the control reproduction number determines the stability of the HIV/AIDS-free equilibrium point. To align our model with the empirical data, we estimate its parameters using prevalence data from the top four countries affected by HIV/AIDS, namely, Eswatini, Lesotho, Botswana, and South Africa. We employ numerical simulations and conduct elasticity and sensitivity analyses to examine how our model parameters influence the control reproduction number and the dynamics of each model compartment. Our findings reveal that each country displays distinct sensitivities to the model parameters, implying the need for tailored strategies depending on the target country. Autonomous simulations highlight the potential of case detection and condom use in reducing HIV/AIDS prevalence. Furthermore, we identify that the quality of condoms plays a crucial role: with higher quality condoms, a smaller proportion of infected individuals need to use them for the potential eradication of HIV/AIDS from the population. In our optimal control simulations, we assess population behavior when control interventions are treated as time-dependent variables. Our analysis demonstrates that a combination of condom use and case detection, as time-dependent variables, can significantly curtail the spread of HIV while maintaining an optimal cost of intervention. Moreover, our cost-effectiveness analysis indicates that the condom use intervention alone emerges as the most cost-effective strategy, followed by a combination of case detection and condom use, and finally, case detection as a standalone strategy.

Prevalence and Epidemiological Characteristics of Anogenital Warts Among Recently Diagnosed HIV-Positive Women on Antiretroviral Therapy in Lagos, Nigeria.

Background Anogenital warts (AGWs) are a prevalent condition resulting from human papillomavirus (HPV) infection, which is the most frequently encountered sexually transmitted infection (STI) on a global scale. Women who are HIV-positive experience a disproportionately high burden of AGWs compared to other populations. It is imperative to comprehend the epidemiological factors linked to the disease within this particular at-risk population. Objectives The objective of the study was to ascertain the prevalence of AGWs and its demographic and socio-biological epidemiological features among recently diagnosed HIV-positive women (HPW) in Lagos, Nigeria. Materials and methods The research was a descriptive cross-sectional study conducted among a sample of 420 recently diagnosed HPW. The study was conducted at the HIV clinic of a tertiary health institution located in Lagos, Nigeria. The participants clinically diagnosed with AGWs were classified as the study group, while individuals without AGWs were classified as the comparison group. Interviewer-administered pretested questionnaires were utilized to gather pertinent demographic and socio-biological epidemiological data from the participants involved in the study. The data were analyzed using IBM SPSS Statistics for Windows, Version 23.0 (Released 2015; IBM Corp., Armonk, New York, USA). Results The prevalence of AGWs among recently diagnosed HPW was found to be 8.5% (34/402). These warts were frequently observed on the vulvar labia (35.3%, 12/34), vaginal walls (14.7%, 5/34), and perianal region (14.7%, 5/34). It is worth noting that over a third of cases (35.3%, 12/34) involved multiple areas within the anogenital region. The diagnosis of AGWs was found to have significant associations with occupation (p=0.005), marital status (p<0.001), and educational status (p=0.028). The majority of HPW diagnosed with AGWs were unemployed (32.4%, 11/34), single (47.1%, 16/34), and did not have tertiary education (94.1%, 32/34). The utilization of oral contraceptive pills (OCPs), smoking, low CD4 count, and high viral load were the significant socio-biological factors associated with the diagnosis of AGWs (p<0.001, respectively). Conclusion The study found that the prevalence of AGW among HPW was 8.5% (34/402). Several epidemiological factors, including occupation, marital status, education, CD4 count, viral load, history of OCP use, and smoking, were found to be significantly associated with the diagnosis of AGW. There is a need to conduct more comprehensive studies to thoroughly assess the impact of these epidemiological factors.

The effects of food insecurity on hepatic steatosis and fibrosis in people with HIV.

BACKGROUND & AIMS: Food insecurity (FI) is a risk factor for nonalcoholic fatty liver disease (NAFLD) and advanced fibrosis in the general population, but its impact on liver disease in people with HIV (PWH) is unknown. METHODS: We examined the association of FI with prevalence of NAFLD and fibrosis in a diverse cohort of PWH. PWH aged ≥18 years on antiretroviral therapy, HIV RNA<200 copies/mL, and without other known liver diseases were screened for NAFLD (CAP≥263 decibels/meter) and advanced fibrosis (LSM≥11 kilopascals) by vibration controlled transient elastography at eight US centers. Participants were categorized as food insecure using the Six-Item Short Form Household Food Security Survey. We used multivariable logistic regression to estimate odds ratios (OR) and 95% confidence intervals (CI) of NAFLD and advanced fibrosis by FI status. RESULTS: Among 654 PWH, NAFLD was present in 348 (53%) and advanced fibrosis in 41 (6%). FI was present in 203 (31%) of participants, including 97/348 (28%) with NAFLD and 18/41 (44%) with advanced fibrosis. In multivariable analysis, FI was associated with lower odds of NAFLD (OR=0.57,95%CI:0.37-0.88) and a greater, but nonsignificant, odds of advanced fibrosis (OR=1.38,95%CI:0.65-2.90). We identified a significant interaction between FI and diabetes (p=0.02) on fibrosis risk, with a greater odds of fibrosis among food insecure PWH and diabetes (OR=3.83,95%CI:1.15-12.73) but not among food insecure nondiabetics (OR=1.12,95%CI:0.47-2.98). CONCLUSIONS: FI is highly prevalent among PWH and associated with lower odds of NAFLD, and among PWH with diabetes, a greater odds of advanced fibrosis. FI may contribute to hepatic fibrosis through mechanisms other than steatosis in PWH.

Homecare workers - an untapped resource in preventing emergency department visits among older individuals? A qualitative interview study from Sweden.

BACKGROUND: Older individuals with functional decline and homecare are frequent visitors to emergency departments (ED). Homecare workers (HCWs) interact regularly with their clients and may play a crucial role in their well-being. Therefore, this study explores if and how HCWs perceive they may contribute to the prevention of ED visits among their clients. METHODS: In this qualitative study, 12 semi-structured interviews were conducted with HCWs from Sweden between July and November 2022. Inductive thematic analysis was used to identify barriers and facilitators to prevent ED visits in older home-dwelling individuals. RESULTS: HCWs want to actively contribute to the prevention of ED visits among clients but observe many barriers that hinder them from doing so. Barriers refer to care organisation such as availability to primary care staff and information transfer; perceived attitudes towards HCWs as co-workers; and client-related factors. Participants suggest that improved communication and collaboration with primary care and discharge information from the ED to homecare services could overcome barriers. Furthermore, they ask for support and geriatric education from primary care nurses which may result in increased respect towards them as competent staff members. CONCLUSIONS: HCWs feel that they have an important role in the health management of older individuals living at home. Still, they feel as an untapped resource in the prevention of ED visits. They deem that improved coordination and communication between primary care, ED, and homecare organisations as well as proactive care would enable them to add significantly to the prevention of ED visits.

Virological Suppression and its Predictors Among HIV/AIDS Patients on Antiretroviral Therapy in Ethiopia: Systematic Review and Meta-analysis.

Background: Achieving viral load suppression is crucial for the prevention of complications and deaths related to HIV infection. Ethiopia has embraced the worldwide 95-95-95 target, but there is no national representative information regarding virological suppression. Therefore, this review aims to determine the pooled virological suppression rate and identify the pooled effect of contributing factors of viral suppression for HIV-positive patients on antiretroviral therapy in Ethiopia. Methods: We systematically searched websites and databases, including online repositories, to obtain primary studies. Two reviewers assessed the quality of the included articles using the Newcastle-Ottawa Scale appraisal checklist. Publication bias was checked using Egger's regression test, the heterogeneity of the studies was assessed using I2 statistics and Q statistics, and a sensitivity analysis was performed to identify any outlier results in the included studies. The Der Simonian Laird random-effects model was used to estimate the overall proportion of viral suppression, and STATA 17 statistical software was used for all types of analysis. Results: A total of 21 eligible articles primarily conducted in Ethiopia using HIV program data were used for this quantitative synthesis. The overall pooled virological suppression rate was 71% (95% CI, 64%-77%). The pooled effects of poor adherence to ART (adjusted odds ratio [AOR], 0.33; 95% CI, 0.28-0.40), body mass index (18.5-24.9 kg/m2; AOR, 1.8; 95% CI, 1.37-2.36), disclosure (AOR, 1.41; 95% CI, 1.05-1.89), absence of opportunistic infection (AOR, 1.68; 95% CI, 1.43-1.97), and high baseline viral load count (AOR, 0.65; 95% CI, 0.52-0.81) were identified as significant predictors of viral suppression. Conclusions: The overall pooled percentage of virological suppression was low compared with the global target of viral suppression and the Ethiopian Public Health Institute report. Poor adherence, normal body mass index, disclosure, absence of opportunistic infection, and high baseline viral load count were factors contributing to viral suppression in Ethiopia. Responsible stakeholders should maximize their efforts to achieve the global target of virological suppression by addressing significant predictors.

Evaluation of Adverse Drug Events in Patients on Anti-Retroviral Therapy Regimen at Omdurman Voluntary Counselling and Testing and Anti-Retroviral Therapy Center in Sudan - A Cross-Sectional Study.

Background: Anti-retroviral therapy-related adverse drug events are accounted as a main cause of anti-retroviral therapy non-adherence. In Sudan, pharmacovigilance studies are relatively rare and obstructed by the problem of under-reporting. It is a well-defined issue worldwide and is highly reported in developing countries. This study aimed to evaluate the prevalence of adverse events associated with anti-retroviral therapy among adult patients with immunodeficiency virus at Omdurman Voluntary Counselling and Testing and Anti-retroviral Therapy Center. Methods: The study was a descriptive cross-sectional study conducted through direct interviews with 429 patients at the selected center using the Adverse Drug Events (ADEs) reporting form. The collected data were analyzed by The Statistical Package for Social Sciences. Results: More than half (55.5%) of the participants experienced adverse events, with 48.7% having experienced them at the beginning of treatment. Central nervous system manifestations were the most common adverse events. By using the Naranjo scale, most adverse events showed a "probable" relationship to anti-retroviral medicines. Based on the chi-square test, medication regimen was significantly associated with the presence of ADEs (namely abdominal pain and jaundice) (p values = 0.03 and 0.001), respectively. Conclusion: This study clearly stated that ART-related ADEs are common among Sudanese PLHIV and with central nervous system being the main adverse events. More pharmacovigilance studies and efforts by healthcare providers should be applied targeting ART-related ADEs under-reporting in Sudanese healthcare facilities.

Gastrointestinal Kaposi: A Rare Case Unveiling the Presentation and Management Challenges of an Uncommon Neoplasm in the Digestive Tract.

Gastrointestinal Kaposi's sarcoma (GI-KS), which is frequently observed in individuals with HIV/AIDS, tends to manifest with vague symptoms or may not show any symptoms at all. These symptoms can include abdominal discomfort, nausea, vomiting, and low levels of iron in the blood, and they may worsen as the tumor enlarges, leading to more severe issues such as blockage or perforation of the bowel. Diagnosis usually requires an endoscopy to confirm the presence of GI-SK in individuals showing symptoms. In this case report, we describe a 29-year-old Hispanic male with vague symptomatology, anemia, and a probable unknown bleeding site.

Barriers to Hearing Health Care for Aging Adults: Reframing the Conversation.

Untreated age-related hearing loss (ARHL) is associated with poor health and social outcomes. Treating hearing loss can mitigate these serious issues. Although there are documented barriers to care, we can look at these barriers and potential solutions differently if we view ARHL as a gradual onset, chronic condition. This provides a framework from which to solve problems in line with how other chronic health conditions experienced by aging adults are approached. With this lens, it becomes evident that early identification and treatment of ARHL can be supported by universal senior hearing screening, appropriate Medicare coverage for devices and services, and direct access to audiological care as well as avenues for self-care are necessary ingredients to change the hearing health care landscape.

HIV seroconversion and associated factors among seronegative pregnant women attending ANC in Ethiopia: an institution-based cross-sectional study.

Background: In countries with limited resources, including Ethiopia, HIV is diagnosed using a rapid serological test, which does not detect the infection during the window period. Pregnant women who test negative for HIV on the first test may seroconvert throughout pregnancy. Women who are seroconverted during pregnancy may not have received interventions, as they are considered HIV-negative unless they are retested for HIV at the end of their pregnancy. Due to limited data on HIV seroconversion, this study aimed to measure the extent of HIV seroconversion and to identify associated factors among seronegative pregnant women attending ANC in Ethiopia. Methods: Institution-based cross-sectional study was conducted among HIV-negative pregnant women attending the ANC in Ethiopia between June and July 2020. Socio-demographic, clinical, and behavioral data were collected through face-to-face questionnaires and participants' records review. HIV retesting was performed to determine the current HIV status of pregnant women. The data collected were entered into Epi data version 4.4.1 and were exported and analyzed by SPSS version 25. A p-value < 0.25 in the bivariate analysis was entered into multivariable logistic regression analysis and a p-value of < 0.05 was considered statistically significant. Result: Of the 494 pregnant women who tested negative for HIV on their first ANC test, six (1.2%) tested positive on repeat testing. Upon multivariable logistic regression, pregnant women who have had a reported history of sexually transmitted infections [AOR = 7.98; 95% CI (1.21, 52.82)], participants' partners reported travel history for work frequently [AOR = 6.00; 95% CI (1.09, 32.99)], and sexually abused pregnant women [AOR = 7.82; 95% CI (1.194, 51.24)] were significantly associated with HIV seroconversion. Conclusion: The seroconversion rate in this study indicates that pregnant women who are HIV-negative in early pregnancy are at an ongoing risk of seroconversion throughout their pregnancy. Thus, this study highlights the benefit of a repeat HIV testing strategy in late pregnancy, particularly when the risk of seroconversion or new infection cannot be convincingly excluded. Therefore, repeated testing of HIV-negative pregnant women in late pregnancy provides an opportunity to detect seroconverted pregnant women to enable the timely use of ART to prevent mother-to-child transmission of HIV infection.

The impact of antiretroviral treatment and child-focused unconditional cash transfers on child mortality.

Although there is sufficient evidence in the epidemiological literature that antiretroviral treatment (ART) reduces child mortality, there is limited evidence of its effect in the socio-economic determinants of child mortality literature. Furthermore, evidence on the effect of child focused unconditional cash transfers (UCTs) on child mortality is limited, especially in the African context. Using South Africa's provincial level data over the period 2001 to 2019, we evaluate the effect of ART and child focused UCTs on child mortality. We use the two-stage instrumental variable mean group estimator. We find that ART reduces child mortality. Moreover, we find an inverted U-shaped non-linear relationship between UCTs and child mortality that is contingent to the level of cash transfer coverage. Our analyses also reveal that UCTs improve the effect of ART on child mortality by enhancing access and adherence to treatment. While the focus of our analyses was on the child mortality effects of ART and UCTs, our findings reaffirm the well-documented impacts of factors such as public health expenditure, HIV/AIDS, female education, and health worker density on child mortality. Collectively, the combination of high ART and UCTs coverage, increased public health expenditure, enhanced female education, and improved health worker density, represents value for money for policymakers and funders. These areas should be prioritised to improve child well-being.

Factors associated with voluntary HIV counseling and testing among young students engaging in casual sexual activity: a cross-sectional study from Eastern China.

OBJECTIVES: To investigate the factors associated with voluntary HIV counseling and testing (VCT) among young students engaging in casual sexual activity and to establish a scientific rationale for developing targeted intervention strategies for preventing HIV/AIDS in this population. METHODS: Stratified cluster sampling was used to conduct a survey using questionnaires to collect demographic and behavioral information for statistical analysis. RESULTS: Data from 611 young students, who reported engaging in casual sexual activity, were included in the statistical analysis. Among these, 68 (11.13%) students underwent the VCT. Among young students who engaged in casual sexual activity, those who were non-Zhejiang residents (adjusted odds ratio [aOR]: 2.11; 95% Confidence Interval [CI]: 1.17-3.80), those who had received AIDS-themed lectures or health education courses from the school in the past year (aOR = 3.96, 95% CI = 1.49-10.50), those who had received HIV risk self-assessment conducted by the school in the past year (aOR = 2.31, 95% CI = 1.17-4.59), and those who had engaged in commercial sex activity in the past year (aOR = 1.98, 95% CI = 1.07-3.66) were more inclined to have undergone VCT. Male students (aOR = 0.37, 95% CI = 0.18-0.77) and those who used condoms consistently during casual sexual activity (aOR = 0.45, 95% CI = 0.21-0.97) were less likely to undergo VCT. CONCLUSION: Casual sexual activity was relatively prevalent among young students, posing a potential risk for HIV transmission. These findings will be instrumental in the development more effective HIV prevention and control strategies for young students. Additionally, it highlights the necessity of promoting and popularizing VCT among young students without Zhejiang province residency, who are involved in commercial sexual activity, and/or those who lacking HIV education. Moreover, additional research and implementation of refined HIV behavioral interventions specifically tailored to young students are necessary to enhance their awareness and knowledge of HIV prevention.

A Blast From the Past: Toxoplasmic Encephalitis As the Initial Presentation of HIV/AIDS.

Many opportunistic infections (OIs) seen early in the human immunodeficiency virus (HIV) epidemic receded in prevalence with the advent of antiretroviral therapy (ART). Despite the availability of early detection and treatment of HIV as well as guidelines for near-universal screening, there remains a sizable population of individuals living with HIV who are not yet aware of their HIV status. These individuals are at risk for OIs such as toxoplasmosis, which would otherwise be preventable with ART and appropriate prophylaxis. Toxoplasmic encephalitis (TE) usually occurs in the late stages of HIV with acquired immunodeficiency syndrome (AIDS), but we present a case of a 38-year-old female with TE as the initial presentation of HIV/AIDS. Testing for the presence of an immunocompromising condition such as HIV is important in patients presenting with focal brain lesions as the differential diagnosis will change, and proper workup may spare invasive procedures such as a brain biopsy.

Willingness and preferences for long-acting injectable PrEP among US men who have sex with men: a discrete choice experiment.

INTRODUCTION: Cabotegravir long-acting injectable HIV pre-exposure prophylaxis (LA-PrEP) was shown to be safe and effective in multiple clinical trials. Increasing uptake and persistence among populations with elevated risk for HIV acquisition, especially among men who have sex with men (MSM), is critical to HIV prevention. OBJECTIVE: This analysis aims to understand potential users' preferences for LA-PrEP, with audience segmentation. DESIGN: Willingness to use and preferences for LA-PrEP were measured in HIV-negative, sexually active MSM in the 2020 American Men's Internet Survey. Respondents answered a discrete choice experiment with paired profiles of hypothetical LA-PrEP characteristics with an opt-out option (no LA-PrEP). Conditional and mixed logit models were run; the final model was a dummy-coded mixed logit that interacted with the opt-out. SETTING: US national online sample. RESULTS: Among 2506 MSM respondents, most (75%) indicated a willingness to use LA-PrEP versus daily oral PrEP versus no PrEP. Respondents were averse to side effects and increasing costs and preferred increasing levels of protection. Respondents preferred a 2-hour time to obtain LA-PrEP vs 1 hour, with a strong aversion to 3 hours. Overall, there was an aversion to opting out of LA-PrEP, with variations: those with only one partner, no/other insurance or who were Black, Indigenous or People of Colour were significantly less likely to prefer LA-PrEP, while those who were Hispanic/Latino, college educated and <40 years significantly preferred LA-PrEP. CONCLUSIONS: A large proportion of MSM expressed a preference for LA-PrEP over daily oral pills. Most respondents chose LA-PrEP regardless of cost, clinic time, side effects or protection level; however, preferences varied by sociodemographics. These varied groups likely require tailored intervention strategies to achieve maximum LA-PrEP uptake and persistence.

Digits-in-Noise Test as an Assessment Tool for Hearing Loss and Hearing Aids.

The aim of this study was to examine the relationship between an American English Digits in Noise (DIN) test and commonly used audiological measures to evaluate the DIN test's ability to detect hearing loss and validate hearing aid fitting. QuickSIN and DIN tests were completed by participants with untreated hearing loss (n = 46), prescription hearing aids (n = 15), and over-the-counter (OTC) hearing aids (n = 12). Performance on the QuickSIN showed moderate positive correlations with DIN for untreated hearing loss participants and prescription hearing aid users, but not for OTC hearing aid users. For untreated hearing loss participants, both QuickSIN and DIN tests showed positive moderate to strong correlations with high frequency puretone averages. In OTC users, DIN scores did not significantly change over a 6-month time period and were better when conducted remotely compared to in-person testing. Our results suggest that the DIN test may be a feasible monitoring option for individuals with hearing loss and those fitted with hearing aids. However, due to small sample size in this pilot study, future research is needed to examine DIN test's utility for fitting and validating OTC hearing aids.

Bone-Anchored Hearing Aid Effects on Vestibular Function: A Preliminary Report.

OBJECTIVE: Cochlear receptors are sensitive to vibratory stimuli. Based on this sensibility, bone-anchored hearing aids have been introduced to correct unilateral or bilateral conductive or mixed hearing loss and unilateral deafness. The vestibular system is also sensitive to the vibratory stimulus and this type of response is used in clinics to test its functionality. Being aware of this double separated sensibility, we wondered whether bone vibration, which activates the acoustic receptors of patients with bone conduction aids, can also influence the functionality of the vestibular system. METHODS: To this end, we recruited 12 patients with a bone-anchored hearing aid and evaluated their vestibular function with and without an activated vibratory acoustic device. RESULTS: Our results show that the vibratory stimulus delivered by the bone conduction aid also reaches and stimulates the vestibular receptors; this stimulation is evidenced by the appearance or modification of some nystagmus findings during bedside vestibular testing. Despite this, none of these patients complained of dizziness or vertigo during prosthesis use. Nystagmus that appeared or changed during acoustic vibratory stimulation through the prosthesis was almost all predominantly horizontal, unidirectional with respect to gaze or body position, inhibited by fixation, and most often consistent with vestibular function tests indicating peripheral vestibular damage. CONCLUSIONS: The findings of sound-evoked nystagmus seem to indicate peripheral rather than central vestibular activation. The occurrence of some predominantly horizontal and high-frequency induced nystagmus seems to attribute the response mainly to the utricle and lateral semicircular canal.

Toxoplasma gondii Infection in Humans: A Comprehensive Approach Involving the General Population, HIV-Infected Patients and Intermediate-Duration Fever in the Canary Islands, Spain.

A prior investigation in 1993 identified a high seroprevalence of toxoplasmosis (63%) in the Canary Islands. This study aims to assess the current prevalence of the disease in diverse population groups. The study was based on a population-scale screening involving 273 residents utilizing T. gondii IgG ELISA and a 20 year retrospective study (1998-2018). This included AIDS/HIV outpatients (1357, of which 324 were residents), AIDS/HIV hospitalized patients (741) and patients with fever of intermediate duration (158). The seroprevalence in the resident population was 37%, with significant differences between islands. Among resident outpatients with AIDS/HIV, 14.2% had specific anti-T. gondii IgG, and three had anti-T. gondii IgM; however, IgG avidity testing indicated non-active infection. In patients hospitalized for AIDS/HIV, T. gondii causing encephalitis was detected in 2%. Among patients with fever of intermediate duration, 28.5% were positive for T. gondii IgG, and four also showed IgM positivity, although the infection was non-active. The study reveals a decrease in human toxoplasmosis over the past 30 years. However, the current seroprevalence, which stands at 37%, together with the substantial risk that T. gondii represents for immunocompromised individuals, highlights the need to implement preventive and control strategies to control the threat that this infection can pose to public health in the Canary Islands population.

"It's a Lot of Closets to Come Out of in This Life": Experiences of Brazilian Gay Men Living with Human Immunodeficiency Virus at the Time of Diagnosis and Its Biopsychosocial Impacts.

We investigated the experiences of Brazilian gay men with HIV, focusing on the moment of diagnosis and its potential biopsychosocial impacts. This clinical-qualitative study involved 15 participants interviewed online and synchronously by a clinical psychologist in 2021. Thematic analysis was employed to analyze the data. Interpretations were grounded in Minority Stress Theory. Four thematic axes emerged, including "Diagnostic Revelation", "Social and Internalized Stigma", "Biopsychosocial Effects of Living with HIV", and "Gratitude for Treatment Advances and the Brazilian Health System". The diagnosis was often experienced as traumatic, exacerbated by the absence of empathy and emotional support from healthcare providers. Participants commonly reported guilt, fear upon learning of their HIV status, social isolation, loneliness, lack of social support, and damage to affective-sexual relationships. Many also noted a decline in mental health, even those without HIV-related medical complications. Despite over 40 years since the HIV epidemic began, the prevalence of homophobia and serophobia among gay men remains widespread, including within the multidisciplinary teams of specialized services. This indicates that the stigma associated with homosexuality and HIV persists, despite significant biomedical progress in the diagnosis and treatment of the infection, particularly in Brazil.

Outcomes of Total Hip Arthroplasty Performed for HIV-Associated Osteonecrosis in China: A Retrospective Cohort Study.

BACKGROUND: In the post-epidemic era, Acquired Immune Deficiency Syndrome (AIDS) remains one of the most prevalent and detrimental infectious diseases worldwide. The incidence of osteonecrosis of the femoral head (ONFH) in AIDS patients is 100 times higher than that in healthy individuals. Although Total Hip Arthroplasty (THA) is ultimately necessary for most patients, there is still a dearth of evidence regarding its safety and efficacy in Chinese AIDS patients. METHODS: The clinical data of 49 patients who met the inclusion and exclusion criteria were retrospectively analyzed. Simultaneously, we categorized patients whose hemoglobin and albumin met a specific threshold as the optimized group and performed group comparisons. RESULTS: There are statistical differences in Harris score and VAS score pre- and post-operation, with a low overall complication rate. Notably, no disparities were observed between the optimized group and the partial optimized group in terms of overall conditions, laboratory examination indicators, severity of ONFH, surgical outcomes, surgical complications, pain perception or functional limitations. Furthermore, no correlation was found between CD4+ T lymphocytes and hemoglobin levels, albumin levels, white blood cell count, or platelet count. CONCLUSION: THA is safe and effective in Chinese AIDS patients with ONFH. However, optimal treatment has limited efficacy in AIDS patients undergoing THA for ONFH. The reconsideration and evaluation of the predictive value of CD4+ T lymphocytes for postoperative complications in joint replacement procedures is warranted.

Reported Unmet Hearing Aid Need in Older People With Dementia: The US National Core Indicators Survey.

OBJECTIVES: Hearing aids have important health benefits for older adults with Alzheimer disease and related dementias (ADRD); however, hearing aid adoption in this group is low. This study aimed to determine where to target hearing aid interventions for American long-term care recipients with ADRD by examining the association of ADRD and residence type with respondent-reported unmet hearing aid need. DESIGN, SETTING, AND PARTICIPANTS: This cross-sectional study used data from the United States National Core Indicators-Aging and Disabilities survey (2015-2019) for long-term care recipients aged ≥65 years. METHODS: We used multivariable logistic regression to model the likelihood of reporting unmet hearing aid need conditional on ADRD status and residence type (own/family house or apartment, residential care, or nursing facility/home), adjusting for sociodemographic factors and response type (self vs proxy). RESULTS: Of the 25,492 respondents [median (IQR) age, 77 (71, 84) years; 7074 (27.8%) male], 5442 (21.4%) had ADRD and 3659 (14.4%) owned hearing aids. Residence types were 17,004 (66.8%) own/family house or apartment, 4966 (19.5%) residential care, and 3522 (13.8%) nursing home. Among non-hearing aid owners, ADRD [adjusted odds ratio (AOR) 0.90, 95% CI 0.80-1.0] and residence type were associated with respondent-reported unmet hearing aid need. Compared to the nursing home reference group, respondents in their own/family home (AOR 1.85, 95% CI 1.61-2.13) and residential care (AOR 1.30, 95% CI 1.10-1.53) were more likely to report unmet hearing aid need. This pattern was significantly more pronounced in people with ADRD than in those without, stemming from an interaction between ADRD and residence type. CONCLUSIONS AND IMPLICATIONS: American long-term care recipients with ADRD living in their own/family home are more likely to report unmet hearing aid need than those with ADRD in institutional and congregate settings. This information can inform the design and delivery of hearing interventions for older adults with ADRD.

Poor durability of the neutralizing response against XBB sublineages after a bivalent mRNA COVID-19 booster dose in persons with HIV.

We estimated the dynamics of the neutralizing response against XBB sublineages and T cell response in persons with HIV (PWH) with previous AIDS and/or CD4 < 200/mm3 receiving the bivalent original strain/BA.4-5 booster dose in fall 2022. Samples were collected before the shot (Day 0), 15 days, 3, and 6 months after. PWH were stratified by immunization status: hybrid immunity (HI; vaccination plus COVID-19) versus nonhybrid immunity (nHI; vaccination only). Fifteen days after the booster, 16% and 30% of PWH were nonresponders in terms of anti-XBB.1.16 or anti-EG.5.1 nAbs, respectively. Three months after, a significant waning of anti-XBB.1.16, EG.5.1 and -XBB.1 nAbs was observed both in HI and nHI but nAbs in HI were higher than in nHI. Six months after both HI and nHI individuals displayed low mean levels of anti-XBB.1.16 and EG.5.1 nAbs. Regarding T cell response, IFN-γ values were stable over time and similar in HI and nHI. Our data showed that in PWH, during the prevalent circulation of the XBB.1.16, EG.5.1, and other XBB sublineages, a mRNA bivalent vaccine might not confer broad protection against them. With a view to the 2023/2024 vaccination campaign, the use of the monovalent XBB.1.5 mRNA vaccine should be urgently warranted in PWH to provide adequate protection.
