ABSTRACT

Despite advances in public policy and health care, it is estimated that more than 1 million people in Brazil live with HIV. Health education is an important prophylactic measure that could help disseminate information to reduce the increase in cases. Among the various strategies used in educational processes, visual media are strong allies due to their significant communication potential. The objective of this study was to analyze the graphic novel "Blue Pills" to identify its potential for addressing HIV in science and biology education. "Blue Pills" is an autobiographical graphic novel by Frederik Peeters that depicts his challenges and anxieties upon discovering that his girlfriend, Cati, and her son are HIV positive. We conducted a content analysis of the work, examining both visual and textual elements to evaluate its potential use in teaching. Our analysis identified 67 excerpts related to the research topic, which we categorized into five themes: "Prejudices and Stigmas," "Care and Treatment," "Transmission and Reproduction of the Virus," "Emotional and Psychological Impacts," and "Social View of Science." Peeters effectively presents HIV in an empathetic and accessible manner, contextualizing complex and often stigmatized issues for readers. Consequently, we believe the material has potential for educational use, despite existing restrictions in the Brazilian National Common Curricular Base (BNCC). Additionally, it contributes to the social debate on issues pertinent to the daily lives of HIV-positive individuals, helping to demystify stigmas entrenched in the collective imagination.


A pesar de los avances en políticas públicas y atención sanitaria, se estima que en Brasil más de 1 millón de personas viven con VIH. La educación sanitaria es un proceso de profilaxis importante que puede contribuir a la difusión de información para mitigar el aumento de casos. Entre las diferentes estrategias utilizadas en los procesos educativos, los productos visuales son fuertes aliados debido a su gran potencial comunicativo. El objetivo de este trabajo fue analizar la novela gráfica "Píldoras Azules" con el fin de identificar su potencial para abordar el VIH en la educación en ciencias y biología. "Píldoras Azules" es una novela gráfica autobiográfica de Frederik Peeters que presenta sus desafíos y angustias al descubrir que su novia Cati y su hijo son VIH positivos. Realizamos un análisis de contenido de la obra, observando los elementos visuales y textuales que pueden posibilitar su uso en la docencia. Tras el análisis, identificamos 67 extractos con enfoques relacionados con el tema objeto de la investigación. Los extractos están organizados en 5 categorías: "Prejuicios y estigmas", "Cuidado y tratamiento", "Transmisión y reproducción del virus", "Impactos emocionales y psicológicos" y "Visión social de la ciencia". En su obra, Peeters logra abordar el VIH de una manera empática y fácil de entender, contextualizando temas complejos y reprimidos en la sociedad para el lector. Por lo tanto, entendemos que el material presenta posibilidades de uso en la enseñanza, a pesar de las restricciones existentes en el BNCC, además de aportar al debate social cuestiones pertinentes a la vida cotidiana de las personas VIH positivas, desmitificando estigmas presentes en el imaginario colectivo.


Apesar dos avanços em políticas públicas e atendimento à saúde, estima-se que no Brasil mais de 1 milhão de pessoas vivam com o vírus da imunodeficiência humana (HIV). A educação em saúde é um importante processo de profilaxia que pode contribuir na disseminação de informações que atenuam o aumento de casos. Dentre as diferentes estratégias utilizadas nos processos educativos, os produtos imagéticos são fortemente aliados devido ao seu grande potencial de comunicação. O objetivo deste trabalho foi analisar o Romance Gráfico (RG) Pílulas Azuis a fim de identificar seu potencial para abordagem sobre o HIV no ensino de ciências e biologia. Pílulas Azuis é um RG autobiográfico de Frederik Peeters que apresenta seus desafios e angústias ao descobrir que sua namorada Cati e seu filho são soropositivos. Realizamos Análise de Conteúdo na obra demonstrando os elementos imagéticos e textuais que podem possibilitar seu uso no ensino. Após a análise, identificamos 67 trechos com abordagens relacionadas ao tema alvo da pesquisa. Os trechos foram organizados em 5 categorias: "preconceitos e estigmas", "Cuidado e tratamento", "Transmissão e reprodução do vírus", "Impactos emocionais e psicológicos" e "Visão social da Ciência". Peeters consegue em sua obra trazer o HIV de forma empática e com fácil compreensão, contextualizando ao leitor temas complexos e reprimidos na sociedade. Assim, identificamos que o material apresenta potencial de utilização no ensino, apesar das restrições existentes na BNCC, assim como trazer para o debate questões sociais pertinentes ao cotidiano de pessoas soropositivas, desmistificando estigmas presentes no imaginário coletivo.

ABSTRACT

Cryptococcal meningitis is an important global health problem, resulting from infection with the yeast Cryptococcus, especially Cryptococcus neoformans and Cryptococcus gattii, which cause a spectrum of disease ranging from pulmonary and skin lesions to life-threatening central nervous system involvement. The diagnosis and management of cryptococcal meningitis have substantially changed in recent years. Cryptococcal meningitis often occurs in people living with advanced HIV infection, though in high-income countries with robust HIV detection and treatment programmes, it increasingly occurs in other groups, notably solid-organ transplant recipients, other immunosuppressed patients and even immunocompetent hosts. This review outlines the clinical presentation, management and prognosis of cryptococcal meningitis, including its salient differences in people living with HIV compared with HIV-negative patients. We discuss the importance of managing raised intracranial pressure and highlight the advantages of improved multidisciplinary team working involving neurologists, infectious disease specialists and neurosurgeons.

ABSTRACT

BACKGROUND: Icon arrays have been shown to be an effective method for communicating medical risk information. However, in practice, icon arrays used to visualize personal risks often differ in the type and color of the icons. The aim of this study was to examine the influence of icon type and color on the perception and recall of cardiovascular risk, as little is known about how color affects the perception of icon arrays. METHODS: A total of 866 participants aged 40 to 90 years representative of the German population in terms of gender and age completed an online experiment. Using a 2 × 2 between-subjects design, participants were randomly assigned to 1 of 4 experimental groups. They received their hypothetical 10-year cardiovascular risk using an icon array that varied by icon type (smiley v. person) and color (black/white v. red/yellow). We measured risk perception, emotional response, intentions of taking action to reduce the risk (e.g., increasing one's physical activity), risk recall, and graph evaluation/trustworthiness, as well as numeracy and graphical literacy. RESULTS: Icon arrays using person icons were evaluated more positively. There was no effect of icons or color on risk perception, emotional response, intentions of taking action to reduce the risk, or trustworthiness of the graph. While more numerate/graphical literate participants were more likely to correctly recall the presented risk estimate, icon type and color did not influence the probability of correct recall. CONCLUSIONS: Differences in the perception of the tested icon arrays were rather small, suggesting that they may be equally suitable for communicating medical risks. Further research on the robustness of these results across other colors, icons, and risk domains could add to guidelines on the design of visual aids. HIGHLIGHTS: The use of different icons and colors did not influence the perception and the probability of recalling the 10-year cardiovascular risk, the emotional response, or the intentions to reduce the presented risk.Icon arrays with person icons were evaluated more positively.There was no evidence to suggest that the effectiveness of the studied icon arrays varied based on individuals' levels of numerical or graphical literacy, nor did it differ between people with or without a history of CVD or on medication for an increased CVD risk.

ABSTRACT

Environmental exposure to toxic chemicals including cadmium (Cd), lead (Pb), and mercury (Hg), are known risk factors for cardiovascular (CVD) and kidney disease. In people living with HIV (PLWH), CVD and kidney disease are the leading cause of death. Neither traditional risk factors nor markers of HIV infection fully explain such an increased risk. It is of paramount importance to establish the epidemiology of toxic chemicals exposure in PLWH, to inform screening and prevention interventions in this vulnerable population. This cross-sectional study compares toxic chemical levels (T-Cd, T-Pb, and T-Hg) among PLWH and HIV-uninfected adults in Northwestern Tanzania. A total of 495 PLWH and 505 HIV-uninfected subjects were analyzed. Spearman's rank correlations were used to examine the relationship between toxic chemical elements by HIV status. Linear regression models were used to determine the association between exposures and outcomes of interest among study participants. In both PLWH and HIV-uninfected adults, blood T-Cd, T-Pb, and T-Hg levels were frequently found at levels above the reference value of 5, 50, and 20 µg/L, respectively. Overall, factors associated with blood toxic chemical levels included vegetable servings per week, obesity, untreated water sources, use of alcohol, and HIV. Among PLWH, weekly vegetable intake provided a protective effect against T-Cd (Coeff = -0.03, 95%CI = -0.06, -0.01) and T-Pb (Coeff = -0.05, 95%CI = -0.09, -0.01) exposure among PLWH. Alcohol intake (Coeff = 0.10, 95%CI = 0.06, 0.13), obesity (Coeff = 0.08, 95%CI = 0.02, 0.13), longer duration to indoor smoke exposure (Coeff = 0.003, 95%CI = 0.001, 0.004), and HIV infection (Coeff = 0.11, 95%CI = 0.07, 0.15) were associated with increased individuals blood T-Hg levels. Individuals in northwestern Tanzania, including PLWH, have high blood levels for T-Cd, T-Pb, and T-Hg. Factors associated with higher blood levels include water sources, obesity, use of alcohol, exposure to indoor smoke, and HIV infection.

ABSTRACT

INTRODUCTION: Diagnosing peritoneal tuberculosis is challenging due to unspecific clinical manifestations, particularly in immunocompromised patients with HIV/AIDS and tuberculosis infections. PRESENTATION OF CASE: An Indonesian man, 26-years-old, complained of mid-abdominal colic and constipation. The patient's present state exhibited symptoms of weakness and paleness, oral candidiasis, a bloated abdomen, palpable discomfort, and shifting dullness. The ascitic fluid analysis showed increased ADA (709 U/L), and detected Mycobacterium tuberculosis using GeneXpert MTB/RIF. Radiographic examination from abdominal x-ray and CT scan revealed a small bowel obstruction. He received intestinal decompression, pain control, intravenous fluid resuscitation, and correction of electrolyte imbalance for small bowel obstruction without any indication for surgical intervention. He also receive first-line ATD for 2 months during intensive phase and 4 months for continuous phase. After a period of 2 weeks following the ATD administration, the patient began taking ARV medication on a daily basis. He showed a good prognosis 6 months following. DISCUSSION: The diagnosis of peritoneal tuberculosis is challenging due to its unspecific manifestation and some cases are identified when complications such as small bowel obstruction appear. The ADA test and GenExpert MTB/RIF are useful instruments for promptly diagnosing tuberculosis. It is suggested to use ARV treatment in individuals with HIV/AIDS who have peritoneal tuberculosis, starting 2 weeks following ATD treatments. CONCLUSION: Peritoneal tuberculosis with small bowel obstruction and HIV/AIDS infection is a rare case in which early diagnosis and monitoring play an important role in successful treatment.

ABSTRACT

DISCLAIMER: In an effort to expedite the publication of articles, AJHP is posting manuscripts online as soon as possible after acceptance. Accepted manuscripts have been peer-reviewed and copyedited, but are posted online before technical formatting and author proofing. These manuscripts are not the final version of record and will be replaced with the final article (formatted per AJHP style and proofed by the authors) at a later time. PURPOSE: Long-acting cabotegravir/rilpivirine (LA-CAB/RPV) was approved for use in virally suppressed patients with human immunodeficiency virus (HIV) in January 2021. While this was a paradigm shift for many patients living with HIV, as LA-CAB/RPV was the first injectable complete regimen for the treatment of HIV, several patient populations, including those lacking virologic suppression, have not been able to easily access this advance in science and care. SUMMARY: In this article, we provide an update on 2 patients from our previous report and describe one further patient who experienced treatment failure following initiation of LA-CAB/RPV. Additionally, we review reports published to date of the clinical outcomes of patients with viremia who have accessed LA-CAB/RPV in the setting of baseline resistance-associated mutations (RAMs) to either component and any resulting RAMs at virologic failure. On the basis of this evidence, we recommend that hybrid or all-injectable regimens be considered for patients who have struggled with adherence to oral antiretroviral therapy or have partial or full resistance to one component of LA-CAB/RPV. CONCLUSION: The case series reported here adds to literature supporting the notion that LA-CAB/RPV can be successfully used in patients who are viremic.

ABSTRACT

Background: Sexual transmission among men who have sex with men (MSM) has become the major HIV transmission route. However, limited research has been conducted to investigate the association between transactional sex (TS) and HIV incidence in China. Objective: This study aims to investigate HIV incidence and distinguish sociodemographic and sexual behavioral risk factors associated with HIV incidence among MSM who engage in TS (MSM-TS) in China. Methods: We conducted a prospective cohort study using a WeChat-based platform to evaluate HIV incidence among Chinese MSM, including MSM-TS in Ningbo, recruited from July 2019 until June 2022. At each visit, participants completed a questionnaire and scheduled an appointment for HIV counseling and testing on the WeChat-based platform before undergoing offline HIV tests. HIV incidence density was calculated as the number of HIV seroconversions divided by person-years (PYs) of follow-up, and univariate and multivariate Cox proportional hazards regression was conducted to identify factors associated with HIV incidence. Results: A total of 932 participants contributed 630.9 PYs of follow-up, and 25 HIV seroconversions were observed during the study period, resulting in an estimated HIV incidence of 4.0 (95% CI 2.7-5.8) per 100 PYs. The HIV incidence among MSM-TS was 18.4 (95% CI 8.7-34.7) per 100 PYs, which was significantly higher than the incidence of 3.2 (95% CI 2.1-5.0) per 100 PYs among MSM who do not engage in TS. After adjusting for sociodemographic characteristics, factors associated with HIV acquisition were MSM-TS (adjusted hazard ratio [aHR] 3.93, 95% CI 1.29-11.93), having unprotected sex with men (aHR 10.35, 95% CI 2.25-47.69), and having multiple male sex partners (aHR 3.43, 95% CI 1.22-9.64) in the past 6 months. Conclusions: This study found a high incidence of HIV among MSM-TS in Ningbo, China. The risk factors associated with HIV incidence include TS, having unprotected sex with men, and having multiple male sex partners. These findings emphasize the need for developing targeted interventions and providing comprehensive medical care, HIV testing, and preexposure prophylaxis for MSM, particularly those who engage in TS.

ABSTRACT

BACKGROUND: CD4 measurement is pivotal in the management of advanced HIV disease. VISITECT® CD4 Advanced Disease (AccuBio Limited, Alva, UK; VISITECT) is an instrument-free, point-of-care, semi-quantitative test allowing visual identification of a CD4 ≤200 cells/µl, or >200 cells/µl from finger-prick or venous blood. METHODS: As part of a diagnostic accuracy study of FUJIFILM SILVAMP TB LAM (clinicaltrials.gov: NCT04089423), people living with HIV of ≥18 years old were prospectively recruited in seven countries from outpatient departments if a tuberculosis symptom was present, and from inpatient departments. Participants provided venous blood for CD4 measurement using flow cytometry (reference standard) and finger-prick blood for VISITECT (index text), performed at point-of-care. Sensitivity, specificity, and positive and negative predictive values of VISITECT to determine a CD4 ≤200 cells/µl were evaluated. RESULTS: Among 1604 participants, the median flow cytometry CD4 was 367 (IQR 128-626) cells/µl and 521 (32.5%) had a CD4 ≤200 cells/µl. VISITECT sensitivity was 92.7% (483/521, 95% CI 90.1-94.7%) and specificity was 61.4% (665/1083, 95% CI 58.4-64.3%). For participants with a CD4 between 0-100, 101-200, 201-300, 301-500, and >500 cells/µl, VISITECT misclassified 4.5% (95% CI 2.5-7.2%), 12.5 (95% CI 8.0-18.2%), 74.1% (95% CI 67.0-80.5%), 48.0% (95% CI 42.5-53.6%), and 22.6% (95% CI 19.3-26.3%), respectively. CONCLUSIONS: VISITECT's sensitivity, but not specificity, met the World Health Organization's minimal sensitivity and specificity threshold of 80% for point-of-care CD4 tests. VISITECT's quality needs to be assessed and its accuracy optimized. VISITECT´s utility as CD4 triage test should be investigated.

ABSTRACT

Existing studies examining resilience among sexual minority men (SMM) have been limited by only analyzing 1 level of resilience. We therefore investigated the impact of multiple levels of resilience on the bidirectional relationship between loneliness and depression symptoms among older SMM. Loneliness, depression symptoms, and multilevel resilience scores were collected across 3 time points (October 2016 to March 2017 [T1]; October 2017 to March 2018 [T2]; and October 2018 to March 2019 [T3]) among 1,264 SMM aged 40 years and older living with and without HIV. Longitudinal mediation models were used to test the mediating effect of the multilevel resilience factors at T2 on the bidirectional relationship between loneliness and depression symptoms, adjusting for sociodemographic covariates. The multilevel resilience factors were negatively associated with loneliness and depression symptoms at T1. The individual-level global resilience factor was associated with decreased odds of depression symptoms (odds ratio [OR] = 0.50; 95% CI, 0.32-0.78), while the interpersonal-level relationship confidence (OR = 0.43; 95% CI, 0.24-0.77) and reliability (OR = 0.36; 95% CI, 0.15-0.84) factors were associated with decreased odds of loneliness at T3. The total effect of loneliness at T1 on depressive symptoms at T3 was ß = 0.20 (95% CI, 0.11-0.28) and was reduced to ß = 0.08 (95% CI, -0.04 to 0.20) after the inclusion of the multilevel resilience factors. The total effect of depressive symptoms at T1 on loneliness at T3 was similar (ß = 0.21; 95% CI, 0.13-0.28) with the direct effect of ß = 0.01 (95% CI, -0.08 to 0.11) after the inclusion of the multilevel resilience factors. Regarding specific indirect effects, individual-level global resilience (depression symptoms at T3 only) as well as the interpersonal-level relationship reliability and confidence (loneliness at T3 model only) factors were statistically significant. Multilevel resilience factors mediated the bidirectional relationship between loneliness and depression symptoms. Mental health interventions should consider implementing resilience-informed strategies that mitigate depression symptoms and loneliness among older SMM.


RESUMEN: Los estudios existentes que examinan la resiliencia entre los hombres de minorías sexuales (HSH) se han visto limitados por analizar sólo 1 nivel de resiliencia. Por lo tanto, investigamos el impacto de múltiples niveles de resiliencia en la relación bidireccional entre la soledad y los síntomas de depresión entre los hombres mayores de minorías sexuales. Se recopilaron datos sobre soledad, síntomas de depresión y resiliencia multinivel a lo largo de 3 puntos temporales (octubre de 2016 a marzo de 2017 [T1]; octubre de 2017 a marzo de 2018 [T2]; y octubre de 2018 a marzo de 2019 [T3]) entre 1,264 SMM de 40 años o más que viven con y sin VIH. Se utilizaron modelos de mediación longitudinal para probar el efecto mediador de los factores de resiliencia multinivel en T2 sobre la relación bidireccional entre la soledad y los síntomas de depresión, ajustando por covariables sociodemográficas. Los factores de resiliencia multinivel se asociaron negativamente con la soledad y los síntomas de depresión en T1. El factor de resiliencia global a nivel individual se asoció con menores probabilidades de síntomas de depresión (odds ratio [OR] = 0,50; IC 95%, 0,32 − 0,78), mientras que el factor de confianza en las relaciones a nivel interpersonal (OR = 0.43; 95% CI, 0.24­0.77) y los factores de fiabilidad (OR = 0.36; 95% CI, 0.15­0.84) se asociaron con menores probabilidades de soledad en T3. El efecto total de la soledad en T1 sobre los síntomas depresivos en T3 fue ß = 0.20 (95% CI, 0.11­0.28) y se redujo a ß = 0.08 (95% CI, -0.04 to 0.20) tras la inclusión de los factores de resiliencia multinivel. El efecto total de los síntomas depresivos en T1 sobre la soledad en T3 fue similar (ß = 0.21; 95% CI, 0.13­0.28) con el efecto directo de ß = 0.01 (95% CI, -0.08 to 0.11) tras la inclusión de los factores de resiliencia multinivel. En cuanto a los efectos indirectos específicos, los factores de resiliencia global a nivel individual (síntomas de depresión sólo en T3) así como la fiabilidad y confianza de las relaciones interpersonales (soledad en el modelo T3 solamente) fueron estadísticamente significativos. Los factores de resiliencia multinivel mediaron la relación bidireccional entre la soledad y los síntomas de depresión. Las intervenciones de salud mental deberían considerar la implementación de estrategias basadas en la resiliencia que mitiguen los síntomas de la depresión y la soledad entre los SMM mayores.

ABSTRACT

BACKGROUND: HIV-related stigma, discrimination, and social marginalization undermines optimal HIV care outcomes. More research examining the impact of HIV-related stigma, discrimination, other interlocking forms of oppression, and antiretroviral therapy (ART) adherence is needed to optimize HIV treatment programming. This study uses data from two clinics in the Dominican Republic to examine client and healthcare worker (HCW) perceptions of HIV and intersectional stigmas among people living with HIV. METHODS: Surveys exploring demographics, HIV-related stigma, various dimensions of discrimination (race/ethnicity, HIV status, sexual orientation), healthcare engagement, and medication adherence were collected from 148 clients and 131 HCWs. Analysis of variance was conducted to examine differences in stigma by clinic and logistic regressions were used to determine predictors of optimal client medication adherence. RESULTS: Perceived discrimination in healthcare facilities due to clients' sexual orientation retained significance in crude and multivariable logistic regression models and was negatively associated with ART adherence (aOR:0.79; 95% CI:0.66, 0.95). DISCUSSION: Findings highlight the importance of implementing strategies to address stigma, discrimination, and social marginalization, particularly within healthcare facilities.

ABSTRACT

Histoplasmosis is a fungal disease associated with substantial mortality rates among persons with advanced HIV disease. Our systematic review synthesized data on the global prevalence of Histoplasma--caused antigenuria in persons with HIV. We searched PubMed/Medline, Embase, and Scopus databases on January 3, 2023, to identify cross-sectional and cohort studies evaluating Histoplasma antigenuria prevalence among adults with HIV infection. We calculated point estimates and 95% CIs to summarize prevalence. Of 1,294 studies screened, we included 15. We found Histoplasma antigenuria among 581/5,096 (11%; 95% CI 11%-12%) persons with HIV and 483/3,789 persons with advanced HIV disease (13%; 95% CI 12%-14%). Among persons with HIV and symptoms consistent with histoplasmosis, Histoplasma antigenuria prevalence was 14% (95% CI 13%-15%; 502/3,631 participants). We determined that persons with advanced HIV disease, inpatients, and symptomatic persons might benefit from a systematic approach to early detection of histoplasmosis using urine antigen testing.

ABSTRACT

BACKGROUND: Toxoplasmosis is caused by the protozoan parasite Toxoplasma gondii, a food- and water-borne zoonotic protozoan parasite that is able to infect almost all warm-blooded vertebrates. It has a major effect on public health, particularly in underdeveloped nations. Immune-competent individuals typically exhibit no symptoms or experience a mild influenza-like sickness, while there is a possibility of severe manifestation and fatal or high-risk for life-threatening diseases in immunocompromised people like pregnant women and HIV/AIDS patients and lead to severe pathological effects on the fetus. METHOD: We conducted a systematic search of databases (PubMed, Google Scholar, Science Direct, EMBASE, and Scopus) using the PRISMA criteria. We used specific keywords such as Toxoplasma gondii, Toxoplasmosis, pregnant women, prevalence, HIV/AIDS, and worldwide studies published from 2018 to 2022. We use Stata (version 14) software to estimate the pooled prevalence and heterogeneity of toxoplasmosis in pregnant women and HIV-infected people using a random-effects model and the Cochran's Q-test, respectively. The Joanna Briggs Institute Critical Appraisal Instrument and Egger's regression asymmetry test were used to assess study quality and publication bias, respectively, while the single study omission analysis was used to test the robustness of a pooled estimate. RESULTS: We included and analyzed a total of 12,887 individuals in this review. The pooled prevalence of T. gondii in this review was 40% (95% CI = 0.31-0.50). The sub-group analysis revealed that the evaluation included 11,967 pregnant women. In pregnant women, the pooled sero-prevalence was 40% (95% CI = 0.31-0.50). In pregnant women and HIV/AIDS patients, 920 individuals were evaluated, and the pooled sero-prevalence was 41% (95% CI = 0.20-0.61). CONCLUSION: This review identified an overall sero-prevalence of Toxoplasma infection of 40% among pregnant women and HIV/AIDS. The expansion of prevention and control strategies, with a primary focus on enhancing educational initiatives, is necessary to avoid reactivation and stop the spread of infection, so investigative sero-prevalence is important work among pregnant women and HIV patients. In order to achieve a comprehensive explanation of the disease condition and reach this goal, we conducted a systematic review and meta-analysis in Worldwide for future use.

ABSTRACT

In this article, we considered a nonlinear compartmental mathematical model that assesses the effect of treatment on the dynamics of HIV/AIDS and pneumonia (H/A-P) co-infection in a human population at different infection stages. Understanding the complexities of co-dynamics is now critically necessary as a consequence. The aim of this research is to construct a co-infection model of H/A-P in the context of fractional calculus operators, white noise and probability density functions, employing a rigorous biological investigation. By exhibiting that the system possesses non-negative and bounded global outcomes, it is shown that the approach is both mathematically and biologically practicable. The required conditions are derived, guaranteeing the eradication of the infection. Furthermore, adequate prerequisites are established, and the configuration is tested for the existence of an ergodic stationary distribution. For discovering the system's long-term behavior, a deterministic-probabilistic technique for modeling is designed and operated in MATLAB. By employing an extensive review, we hope that the previously mentioned approach improves and leads to mitigating the two diseases and their co-infections by examining a variety of behavioral trends, such as transitions to unpredictable procedures. In addition, the piecewise differential strategies are being outlined as having promising potential for scholars in a range of contexts because they empower them to include particular characteristics across multiple time frame phases. Such formulas can be strengthened via classical techniques, power law, exponential decay, generalized Mittag-Leffler kernels, probability density functions and random procedures. Furthermore, we get an accurate description of the probability density function encircling a quasi-equilibrium point if the effect of H/A-P minimizes the propagation of the co-dynamics. Consequently, scholars can obtain better outcomes when analyzing facts using random perturbations by implementing these strategies for challenging issues. Random perturbations in H/A-P co-infection are crucial in controlling the spread of an epidemic whenever the suggested circulation is steady and the amount of infection eliminated is closely correlated with the random perturbation level.

ABSTRACT

Pregnant and lactating persons in sub-Saharan Africa face a heightened risk of HIV acquisition, due to biological and behavioral factors, combined with limited access to prevention and treatment services. Oral pre-exposure prophylaxis (PrEP) and the dapivirine vaginal ring are promising tools for HIV prevention, and the ring's recent approval in multiple African countries represents a significant advancement in expanding access to HIV prevention. In a nested qualitative study within the MTN-042 trial, we explored the acceptability of study products among pregnant persons in the second and early third trimesters. Interviews were conducted privately, using a semi-structured guide with 77 participants, in participants' preferred language. Topics explored included product acceptability (using the theoretical framework of acceptability), user experience, satisfaction, disclosure, community attitudes, and sexual activity during pregnancy. Interview transcripts were analyzed using Dedoose software. We observed positive attitudes among participants towards the study products, which they found generally user-friendly, despite the added complexities of using them during pregnancy. Participants recognized that consistent and correct use would provide protection for both them and their unborn children. Although initial concerns existed, most of these worries dissipated over time, with study staff support and increased product use experience. These findings emphasize the importance of continued surveillance, support, and education to ensure the successful rollout of new HIV prevention measures during pregnancy.

ABSTRACT

Human immunodeficiency virus (HIV) infection remains an important global public health problem. About 40 million people are infected with HIV, and this infection caused about 630,000 deaths in 2022. The hallmark of HIV infection is the depletion of CD4+ T helper lymphocytes (Th cells). There are at least seven different Th subtypes, and not all are the main targets of HIV. Moreover, the effect of the virus in a specific subtype can be completely different from that of the others. Although the most compromised Th subtype in HIV infection is Th17, HIV can induce important dysregulations in other subtypes, such as follicular Th (Tfh) cells and regulatory Th cells (Treg cells or Tregs). Several studies have shown that HIV can induce an increase in the immunosuppressive activity of Tregs without causing a significant reduction in their numbers, at least in the early phase of infection. The increased activity of this Th subtype seems to play an important role in determining the immunodeficiency status of HIV-infected patients, and Tregs may represent a new target for innovative anti-HIV therapies, including the so-called "Kick and Kill" therapeutic method whose goal is the complete elimination of the virus and the healing of HIV infection. In this review, we report the most important findings on the effects of HIV on different CD4+ T cell subtypes, the molecular mechanisms by which the virus impairs the functions of these cells, and the implications for new anti-HIV therapeutic strategies.

ABSTRACT

As extreme weather events like floods and storms continue to increase, it is crucial to examine the degree to which various disaster preparedness and mitigation investments can lower these risks. In this research, we empirically examine the effects of multiple federal disaster aid programs on reducing subsequent flood- and storm-related damages across US coastal states. Our analysis distinguishes aid programs and their funded projects targeting different emergency management functions, including preparedness, nonstructural and structural mitigation, emergency response and protective measures, and rehabilitation of public infrastructure. We construct panel data of more than 1800 US counties over the years 2000-2019 and estimate a fixed-effects model with time-varying county-level socioeconomic and demographic characteristics. We find that disaster aid generally helps mitigate property damages, although this loss-reduction effect varies by program. Among all aid programs, the Emergency Management Performance Grant results in the largest reduction of future flood damages. The Public Assistance grants supporting emergency work are also found to exert a strong effect on risk reduction. We also find that the impacts of disaster aid are higher in coastal counties. Our study is one of the first few examining the resilience implication of disaster aid in coastal counties, and our results underscore the importance of investing in capacity building, contingency planning, and consistency in maintenance.

ABSTRACT

BACKGROUND: Checklists are a common tool used in order to mitigate risks caused by human factors and can facilitate the safe induction of anesthesia as well as handovers. SBAR (Situation, Background, Assessment, Recommendation) is a checklist recommended by the WHO and DGAI for handovers, while SOAP-M (Suction, Oxygen, Airway, Pharmaceuticals, Monitoring) is a checklist for the induction of anesthesia. This study investigates the implementation and adoption of these two checklists. METHODS: We conducted a single-center online survey one year after the implementation of SOAP-M and SBAR at a university hospital's anesthesiology department, using scales from three validated questionnaires to assess safety attitudes as well as the behavior of staff and the perceived usefulness of the checklists. RESULTS: Staff with a high score in general attitude towards patient safety, as determined by the safety attitudes questionnaire, considered both checklists useful additions to their work environment. Nurses and physicians (p = 0.102) as well as groups divided according to work experience (p = 0.077) showed no significant differences in using SOAP-M and SBAR. Perceived usefulness was significantly higher (p < 0.001) among users of the checklists, and the same goes for positive reinforcement (p < 0.001), social cues (p = 0.0215) and goal cues (p = 0.0252). CONCLUSION: SOAP-M and SBAR are perceived as useful checklists for patient handovers and anesthesia induction by tertiary referral hospital's employees with high score in general safety attitude and were therefore commonly used one year after their introduction. No significant difference in checklist adoption between occupations as well as groups divided according to work experience could be found. Perceived usefulness is significantly higher among users of the checklist, who feel using the checklists provides more support.

ABSTRACT

We investigated whether cement pastes are a possible source of ecotoxicologically potent substances. For this purpose, leaching according to DIN EN 16637-2 was performed on portland cement pastes as well as blast furnace slag cement with and without an air entraining agent (AEA). The AEA, consisting of wood rosin and resin, contained the stabiliser drometrizole and the biocide octylisothizolinone (OIT), which was confirmed by our non-target screening (NTS). Our ecotoxicological studies (Daphnia magna, Aliivibrio fischeri and Desmodesmus subspicatus) of the pure cement eluates showed no effects at all. In these samples, it was possible to attribute up to 85 % of the dissolved organic carbon (DOC) to acetate, formate and diethylene glycol (DiEG). Eluates from cements with AEA contained up 70 µg/L octylisothizolinone (OIT), and no drometrizole was found. 90 % of the total OIT release happened within the first 6 h. It was possible to attribute the observed ecotoxicological effects mainly to the OIT concentrations. Additional leaching with elevated sulphate concentrations (800 mg/l) did not influence the release of DOC and OIT or increase the ecotoxicological effects. As a consequence, we advise curing the cement paste for 24 h prior to use, as this largely avoids the release of OIT and the observed ecotoxicological effects.

ABSTRACT

INTRODUCTION: HIV has transitioned from a devastating 1980s epidemic to a manageable chronic condition with antiretroviral therapy. In Brazil, challenges persist, including high detection rates and loss of medical follow-up among people living with HIV/AIDS (PLHIV). Adherence, engagement, and avoiding loss to follow-up are critical for effective HIV/AIDS prevention and care. OBJECTIVES: This case-control study within longitudinal research on PLHIV linkage and retention in Porto Alegre aims to analyze factors associated with treatment abandonment. METHODS: The study, based on patients from the Therapeutic Care Service for HIV and AIDS at Sanatorio Partenon Hospital, involved 360 PLHIV in a retention and linkage outpatient clinic. RESULTS: Risk factors for loss to follow-up include cisgender women, diagnosis between 1991 and 2005, and non-adherence to antiretroviral treatment (ART). Conversely, cisgender men, diagnosis between 2015 and 2023, and good ART adherence were protective factors. CONCLUSION: Gender disparities and ART non-adherence pose significant challenges in comprehensive PLHIV care. Cisgender women diagnosed before 2005 face higher risk, while cisgender men diagnosed after 2015 with good ART adherence are more protected, influencing care and prevention strategies for PLHIV.

ABSTRACT

Background The emergence of dolutegravir (DTG) within antiretroviral therapy (ART) has drastically improved the management of HIV/AIDS, marking a shift toward a chronic manageable condition. Nevertheless, concerns persist regarding the real-world tolerability and adverse effects (AEs) of DTG. Objective This study aims to explore the clinical characteristics, adverse reactions, and adherence to treatment with DTG among HIV-positive individuals. Methods Through a prospective approach, we examined HIV-positive patients undergoing DTG-based ART regimens. Key parameters, including socio-demographic data, treatment adherence, and clusters of differentiation 4 (CD4) count, were evaluated. Enrolled patients were followed up for six months for the development of comorbidities and AEs. Results Initial observations indicate successful viral suppression and enhanced CD4 counts with DTG-based regimens, t(318)=2.0664, p=0.0392. However, a subset of participants experienced AEs such as neuropsychiatric symptoms (headaches and mood fluctuations), unintended weight gain, and other comorbidities linked to prolonged ART usage. Conclusion While DTG-based therapies offer substantial advantages in HIV/AIDS management, such as rapid viral suppression and reduced toxicity, ongoing vigilance for adverse effects, particularly neuropsychiatric symptoms and metabolic disturbances, is imperative for optimizing patient care. Further research is necessary to fully elucidate the safety profile of DTG in real-world scenarios and mitigate potential adverse reactions.
