RESUMO

INTRODUCTION: HIV pre-exposure prophylaxis (PrEP) is effective at reducing HIV transmission. However, PrEP uptake is low for racial and ethnic minorities and women, especially in the Southern US Health care clinicians should be prepared to identify all patients eligible for PrEP, provide counseling, and prescribe PrEP. METHODS: Retrospective analysis of persons newly diagnosed with HIV was conducted at a large public health system from January 2015 to June 2021. Interactions with the health system in the 5 years preceding HIV diagnosis were analyzed, and missed opportunities for HIV prevention interventions, including PrEP and condom use counseling, were identified. RESULTS: We identified 454 patients with a new HIV diagnosis with previous health system interactions. 166(36.6%) had at least 1 identifiable indication for PrEP: 42(9.3%) bacterial STI, 63(13.9%) inconsistent condom use, or 82(18%) injection drug use before HIV diagnosis. Only 7(1.5%) of patients were counseled on PrEP. Most patients (308; 67.8%) had no documented condom use history in the EHR before diagnosis, a surrogate marker for obtaining a sexual history. Patients who exclusively interacted with the emergency care setting did not receive PrEP education and were less likely to receive condom use counseling. CONCLUSION: Missed opportunities to offer HIV prevention before diagnosis were common among patients newly diagnosed with HIV. Most patients did not have sexual history documented in the chart before their HIV diagnosis. Educational interventions are needed to ensure that clinicians are prepared to identify those eligible and discuss the benefits of PrEP.

RESUMO

OBJECTIVE: To describe cases of Kaposi's sarcoma-associated herpesvirus (KSHV)-associated multicentric Castleman's disease (MCD) and primary effusion lymphoma (PEL) in patients with HIV from a large, safety-net hospital system in Dallas, Texas, USA. METHODS: We conducted a retrospective review of patients with HIV-associated PEL and/or MCD. RESULTS: Twelve patients with PEL and 10 patients with MCD were identified. All patients were male and 17 of 20 were men who have sex with men; 66.7% of PEL patients and 50% of MCD patients had concurrent KS at the time of diagnosis; 42% of patients with PEL and 20% of patients with MCD died during the follow-up period. We noted improved survival in our cohort compared to previous studies, particularly in our PEL patients with a median survival of 11.4 months compared to 3-6-month median survival historically. Median follow-up time for MCD patients was 17.5 months. This improved survival is despite suboptimal antiretroviral therapy (ART) adherence at diagnosis, with only 50% of patients on ART at the time of MCD/PEL diagnosis. CONCLUSION: These data highlight the importance of early recognition of PEL and MCD, and the larger-scale efforts needed to better understand the pathogenetic drivers of clinical outcomes in patients affected by KSHV-related diseases.

RESUMO

BACKGROUND: The Sleep Tiredness Observed Pressure-Body mass index Age Neck circumference Gender (STOP-Bang) questionnaire is a validated preoperative screening tool for identifying patients with obstructive sleep apnea (OSA). Although it has a high sensitivity at scores ≥3, its specificity is moderate, particularly for scores of 3-4. This study aimed to externally validate the STOP-Bang questionnaire and the alternative scoring models that have been proposed to improve its predictive performance. METHODS: This prospective cohort study included 115 surgical patients with preoperative STOP-Bang scores of 3-8. Type 3 sleep recordings identified moderate-to-severe OSA, reflected by an apnea-hypopnea index (AHI) of >15. Patients were categorized into 2 subgroups: patients with an intermediate (STOP-Bang 3-4) or a high risk of OSA (STOP-Bang 5-8). For patients with scores of 3-4, we tested approaches identified in previous studies: stepwise stratification of the STOP-Bang questionnaire and additional preoperative measurement of serum bicarbonate concentrations. RESULTS: The incidence of moderate-to-severe OSA was significantly higher in patients with STOP-Bang scores of 5-8 than in patients with scores of 3-4: 45 of 58 patients (78%) versus 30 of 57 patients (53%), respectively (P < .01). For patients with STOP-Bang scores of 3-4, we found no differences regarding their OSA diagnosis between patients included in the alternative scoring models and those not included. CONCLUSIONS: The STOP-Bang questionnaire detected moderate-to-severe OSA patients when scores reached 5-8. However, its performance was altered in patients with STOP-Bang scores of 3-4, and alternative scoring models with specific combinations of factors failed to improve the screening of these patients.

RESUMO

BACKGROUND AND OBJECTIVES: While older adults' social participation has attracted sustained attention, the realities faced by seniors with impairments in this area are still understudied. Social representations are formed from socially constructed opinions regarding a given object and have four functions (knowledge, identity, orientation, justification). The purpose of this article is to document the social representations that exist within seniors' organizations regarding participation by older people with impairments. RESEARCH DESIGN AND METHODS: In this mixed-methods study, an exploratory sequential design was applied. First, a qualitative phase involved meetings with five focus groups to explore how participants would manage difficult situations in which the inclusion of an older person with impairments must be addressed. Second, a quantitative phase consisted of a questionnaire administered to 86 respondents to examine the components of social representations about the participation of older people with impairments. RESULTS: Results show that, although research participants acknowledge that all seniors have the right to participate, this right confronts a collective identity infused with aging model that demands a youthful, "un-disabled" appearance and activities. In terms of the orientation function, making participation a reality is seen as relying on the efforts of people with impairments, but when there is a failure of inclusiveness, the reasons offered to justify it concern the resources available, rather than possible prejudices. DISCUSSION AND IMPLICATIONS: Interpretation of the results leads to recommendations for both implementing an inclusion philosophy and practices in seniors' organizations and revisiting the view of impairment in old age as otherness.

RESUMO

OBJECTIVE: The aim is to compare the cost-effectiveness of two long-lasting insecticidal nets (LLINs) delivery models (standard vs. new) in universal coverage (UC) campaigns in rural Mozambique. RESULTS: The total financial cost of delivering LLINs was US$ 231,237.30 and US$ 174,790.14 in the intervention (302,648 LLINs were delivered) and control districts (219,613 LLINs were delivered), respectively. The average cost-effectiveness ratio (ACER) per LLIN delivered and ACER per household (HH) achieving UC was lower in the intervention districts. The incremental cost-effectiveness ratio (ICER) per LLIN and ICER per HH reaching UC were US$ 0.68 and US$ 2.24, respectively. Both incremental net benefit (for delivered LLIN and for HHs reaching UC) were positive (intervention deemed cost-effective). Overall, the newer delivery model was the more cost-effective intervention. However, the long-term sustainability of either delivery models is far from guaranteed in Mozambique's current economic context.

RESUMO

BACKGROUND: In 2016/2017, Mozambique conducted a countrywide long-lasting insecticidal nets (LLINs) universal coverage campaign (UCC). This paper aims to describe the planning and implementation process of the campaign in Mozambique. METHODS: A cross-sectional and descriptive design was used for reporting the planning and implementation process of the UCC. The UCC used a collaborative approach, involving institutional and non-institutional actors, namely: National Malaria Control Programme (NMCP), provincial and district health authorities, community members and civil society partners. A new household registration strategy based on coupons, stickers, and one LLIN per two persons as allocation criterion was implemented. The campaign was implemented in phases, allowing for continuous improvement of implementation quality by applying lessons learnt from each phase. RESULTS: A total of 7,049,894 households were registered corresponding to a total of 31,972,626 registered persons. A total of 16,557,818 LLINs were distributed between November 2016 and December 2017, corresponding to 97% of LLINs needs based on household registration, and covering 95% of the registered households (6,708,585 households), resulting in an estimated 85% of the total Mozambican population with LLIN access. CONCLUSIONS: The collaborative planning process and strong coordination of campaign actors allowed Mozambique's NMCP and partners to successfully carry out the first countrywide LLINs UCC in the country. The increased access to LLINs in households will likely result in increased LLIN use and a reduction of the malaria burden in the country, therefore contributing to the achievement of the 2016-2030 Global Technical Strategy for Malaria goals.

RESUMO

BACKGROUND: Malaria is the leading cause of death among children in Mozambique. Prevalence and factors associated with malaria are not well studied among children in rural Zambézia Province. Whether prevalence of malaria varies across diverse districts within the province is unknown. METHODS: A cross-sectional survey of female heads of household was conducted during April and May 2014, a period of peak malaria transmission. Data were collected on up to two randomly selected children aged 6-59 months per household. The outcome of interest was self-report of symptomatic malaria confirmed by diagnostic test in the past 30 days. Analyses accounted for the two-stage cluster sample design. Prevalence of symptomatic malaria was calculated for the province and three over-sampled focus districts-Alto Molócuè, Morrumbala, and Namacurra. Multivariable logistic regression of symptomatic malaria diagnosis included: district, age, sex, education, bed net use, urban setting, distance to health facility, income, roofing material, and pig farming. RESULTS: Data were collected on 2540 children. Fifty percent were female, and the median age was 24 months. Sixty percent of children slept under bed nets the night prior to the survey, but utilization varied between districts (range 49-89%; p < 0.001). Forty-three percent of children reported fever in the past 30 days, 91% of those sought care at a health facility, 67% of those had either a malaria rapid diagnostic test or blood smear, and 67% of those had a positive test result and therefore met our case definition of self-reported symptomatic malaria. There were significant differences in prevalence of fever (p < 0.001), health-seeking (p < 0.001), and diagnostic testing (p = 0.003) between focus districts. Province-wide prevalence of symptomatic malaria was 13% and among focus districts ranged from 14% in Morrumbala to 17% in Namacurra (p < 0.001). Higher female caregiver education (OR 1.88; 95% CI 1.31-2.70), having fewer young children in the household (OR 1.25; 95% CI 1.01-1.56), and higher income (OR 1.56; 95% CI 1.11-2.22) were independently associated with having a child with symptomatic malaria. CONCLUSIONS: Self-reported symptomatic malaria is highly prevalent among children in Zambézia Province, Mozambique and varies significantly between diverse districts. Factors facilitating access to health services are associated with symptomatic malaria diagnosis. These findings should inform resource allocation in the fight against malaria in Mozambique.

RESUMO

Globally, approximately 5.9 million children under 5 years of age died in 2015, a reduction of over 50% since 1990. Millennium Development Goal 4 established the goal of reducing child mortality by two-thirds by 2015. Multiple countries have surpassed this goal; however, regional and within-country inequities exist. We sought to study determinants of health-care utilization among children 6-59 months of age with fever, diarrhea, and respiratory symptoms in Zambézia Province, Mozambique. We conducted a population-based cross-sectional survey of female heads of household between April and May 2014. Mobile teams conducted interviews in 262 enumeration areas, with three distinct districts being oversampled for improved precision. Descriptive statistics and logistic regression using Stata 13.1 and R 3.2.2 were used to examine factors associated with health-care utilization. A total of 2,317 children were evaluated in this study. Mothers' median age was 26 years, whereas child median age was 24 months. The proportion of children reporting fever, diarrhea, or respiratory illness in the prior 30 days was 44%, 22%, and 22%, respectively. Health-care utilization varied with 65% seeking health care for fever, compared with 57% for diarrhea and 25% for respiratory illness. In multivariable logistic regression, the characteristics most associated with health-care utilization across illnesses were delivery of last child at a facility, higher maternal education, and household ownership of a radio. The decision or ability to use health care is a multifaceted behavior swayed by societal norms, values, socioeconomics, and perceived need. Recognizing the predictors of a particular population may offer useful information to increase uptake in health-care services.

RESUMO

BACKGROUND: Malaria remains a major threat to some 3.2 billion persons globally. Malaria contributes heavily to the overall disease burden in Mozambique and is considered endemic. A cornerstone of Mozambique's vector control strategy has been to strive for universal coverage of insecticide-treated nets (ITN). METHODS: The study is a population-based cross-sectional survey of female heads-of-household in Zambézia Province, Mozambique conducted during August-September, 2010 and April-May, 2014. Analyses accounted for a stratified two-stage cluster sample design. Outcomes of interest included sleeping under a mosquito net during the previous night. Descriptive statistics were calculated for three oversampled districts and for the entire province. Multivariable logistic regression analysis was used to estimate factors associated with both changes over time and increased mosquito bed net usage. RESULTS: Of the 3916 households interviewed in 2010 and 3906 households in 2014, 64.3% were in possession of at least one mosquito bed net. A higher proportion of households in Namacurra (90%) reported possession of a mosquito net, compared to Alto Molócuè (77%) and Morrumbala (34%), respectively in 2014. Of pregnant respondents, 58.6% reported sleeping under a mosquito net the previous night in 2010 compared to 68.4% in 2014. Fifty percent of children 0-59 months slept under a mosquito net the previous night in 2010 compared to 60% in 2014. Factors associated with use of a mosquito net for female head-of-household respondents were higher education, understanding Portuguese, larger household size, having electricity in the household, and larger household monthly income. As travel time to a health facility increased (per 1 h), respondents had 13% lower odds of sleeping under a mosquito net (OR 0.87; 95% CI 0.74-1.01, p = 0.07). Pregnant women in 2014 had a 2.4 times higher odds of sleeping under a bed net if they lived in Namacurra compared to Alto Molócuè (95% CI 0.91-6.32, p = 0.002 for district). Higher maternal education, living in Namacurra, and acquisition of mosquito bed nets were associated with a child 0-59 months reporting sleeping under the net in the previous night in 2014. CONCLUSIONS: Intensified focus on the poorest, least educated, and most distant from health services is needed to improve equity of ITN availability and usage. Additionally, while some districts have already surpassed goals in terms of coverage and utilization of ITN, renewed emphasis should be placed on bringing all geographic regions of the province closer to meeting these targets.

RESUMO

BACKGROUND: While many countries are transitioning from epidemics of undernutrition to overnutrition, Mozambique's very high 44% prevalence of stunting in children under age 5 years is cause for serious concern. METHODS: We conducted two population-based cross-sectional surveys of ~4000 female heads of households each in Zambézia Province, Mozambique from August-September 2010 (Baseline) and April-May 2014 (Endline) as part of the USAID funded Strengthening Communities through Integrated Programs (SCIP) grant. Anthropometric measurements were collected on 560 children aged 6-59 months at Baseline and 912 children at Endline and classified as: "stunted," a height-for-age z-score less than -2; "wasted," weight-for-height z-score less than -2; and "underweight," weight-for-age z-score less than -2. Descriptive statistics and logistic regression using Stata 13.1 were used to examine factors associated with undernutrition. RESULTS: Of children under age five years, 43% were undernourished in 2010 and 55% in 2014. The most common form of undernutrition was stunting (39% in 2010, 51% in 2014), followed by underweight (13% in both 2010 and 2014), and wasting (7% in 2010, 5% in 2014). Child's age was found to have a non-linear association with stunting. Vitamin A supplementation was associated with a 31% (p=0.04) decreased odds of stunting. Children who were exclusively breastfed for at least six months had an 80% (p=0.02) lower odds of wasting in 2014 and 57% (p=0.05) decreased odds of being underweight in 2014. Introducing other foods after age six months was associated with a five-fold increased odds of wasting in 2014 (p=0.02); household food insecurity was associated with wasting (OR=2.08; p=0.03) and underweight in 2010 (OR=2.31; p=0.05). Children whose mother washed her hands with a cleaning agent had a 40% (p=0.05) decreased odds of being underweight. Surprisingly, per point increase in household dietary diversity score, children had 12% greater odds of being stunted in 2010 (p=0.01) but 9% decreased odds of being underweight in 2014 (p=0.02). CONCLUSIONS: A combination of household and individual level factors was associated with undernutrition. As such, employment of multidimensional interventions should be considered to decrease undernutrition in children under five years old.

RESUMO

BACKGROUND: Efflux systems are involved in multidrug resistance in most Gram-negative non-fermentative bacteria. We have chosen Burkholderia thailandensis to dissect the development of multidrug resistance phenotypes under antibiotic pressure. METHODOLOGY/PRINCIPAL FINDINGS: We used doxycycline selection to obtain several resistant B. thailandensis variants. The minimal inhibitory concentrations of a large panel of structurally unrelated antibiotics were determined ± the efflux pump inhibitor phenylalanine-arginine ß-naphthylamide (PAßN). Membrane proteins were identified by proteomic method and the expressions of major efflux pumps in the doxycycline selected variants were compared to those of the parental strains by a quantitative RT-PCR analysis. Doxycycline selected variants showed a multidrug resistance in two major levels corresponding to the overproduction of two efflux pumps depending on its concentration: AmrAB-OprA and BpeEF-OprC. The study of two mutants, each lacking one of these pumps, indicated that a third pump, BpeAB-OprB, could substitute for the defective pump. Surprisingly, we observed antagonistic effects between PAßN and aminoglycosides or some ß-lactams. PAßN induced the overexpression of AmrAB-OprA and BpeAB-OprB pump genes, generating this unexpected effect. CONCLUSIONS/SIGNIFICANCE: These results may account for the weak activity of PAßN in some Gram-negative species. We clearly demonstrated two antagonistic effects of this molecule on bacterial cells: the blocking of antibiotic efflux and an increase in efflux pump gene expression. Thus, doxycycline is a very efficient RND efflux pump inducer and PAßN may promote the production of some efflux pumps. These results should be taken into account when considering antibiotic treatments and in future studies on efflux pump inhibitors.
