RESUMO

BACKGROUND: The infection of the liver by Plasmodium parasites is an obligatory step leading to malaria disease. Following hepatocyte invasion, parasites differentiate into replicative liver stage schizonts and, in the case of Plasmodium species causing relapsing malaria, into hypnozoites that can lie dormant for extended periods of time before activating. The liver stages of Plasmodium remain elusive because of technical challenges, including low infection rate. This has been hindering experimentations with well-established technologies, such as electron microscopy. A deeper understanding of hypnozoite biology could prove essential in the development of radical cure therapeutics against malaria. RESULTS: The liver stages of the rodent parasite Plasmodium berghei, causing non-relapsing malaria, and the simian parasite Plasmodium cynomolgi, causing relapsing malaria, were characterized in human Huh7 cells or primary non-human primate hepatocytes using Correlative Light-Electron Microscopy (CLEM). Specifically, CLEM approaches that rely on GFP-expressing parasites (GFP-CLEM) or on an immunofluorescence assay (IFA-CLEM) were used for imaging liver stages. The results from P. berghei showed that host and parasite organelles can be identified and imaged at high resolution using both CLEM approaches. While IFA-CLEM was associated with more pronounced extraction of cellular content, samples' features were generally well preserved. Using IFA-CLEM, a collection of micrographs was acquired for P. cynomolgi liver stage schizonts and hypnozoites, demonstrating the potential of this approach for characterizing the liver stages of Plasmodium species causing relapsing malaria. CONCLUSIONS: A CLEM approach that does not rely on parasites expressing genetically encoded tags was developed, therefore suitable for imaging the liver stages of Plasmodium species that lack established protocols to perform genetic engineering. This study also provides a dataset that characterizes the ultrastructural features of liver stage schizonts and hypnozoites from the simian parasite species P. cynomolgi.

RESUMO

BACKGROUND: In chronic kidney disease (CKD), there are historical inequities in multiple stages of the pathway for organ transplantation. Women have been recognized as disadvantaged within this process even after several efforts. Therefore, we aimed to analyze the prevalence and incidence of CKD by gender and their access to Kidney replacement therapy (KRT) in Colombia. METHODS: A cross-sectional study based on secondary analysis of national information on CKD, hypertension, diabetes, waiting list, deceased, and living donor transplantation between 2015 and 2020. RESULTS: In Colombia, 4.934.914 patients were diagnosed with hypertension, diabetes, or CKD. 60,64% were female, with a mean age of 63.84 years (SD 14,36). Crude incidence for hypertension (10.85 vs. 7.21 /1000 inhabitants), diabetes mellitus (3.77 vs. 2.98 /1000 inhabitants), and CKD (4 vs. 2 /1000 inhabitants) was higher for females. Crude incidence for KRT was 86.45 cases /100.0000 inhabitants. In 2020, 2978 patients were on the waiting list, 44% female. There were 251 deaths on the waiting list, 38% female. This year, 517 kidney transplants were performed, and only 40% were female. CONCLUSION: In Colombia, there are proportionally more females with CKD and precursor comorbidities. Nevertheless, there are fewer females on the waiting list and transplanted annually.

RESUMO

INTRODUCTION: Female sexual interest and arousal disorder (FSIAD) is the most prevalent female sexual dysfunction in the postmenopause. OBJECTIVE: The aim of this review is to provide a summary of the currently available evidence on the use of testosterone in the treatment of FSIAD in postmenopausal women. METHODS: A narrative review on the topic was performed. Only randomized controlled trials (RCTs) and systematic reviews and meta-analysis were considered. 123 articles were screened, 105 of them assessed for eligibility, and finally 9 were included in qualitative synthesis following the PRISMA declaration. RESULTS: Current evidence recommends, with moderate therapeutic benefit, the use of systemic transdermal testosterone within the premenopausal physiological range in postmenopausal women with Hypoactive Sexual Desire Disorder (HSDD), the previous entity for low desire dysfunction, not primarily related to modifiable factors or comorbidities such as relationship or mental health problems. The available evidence is based on studies with heterogeneity on their design (different testosterone doses, routes of administration, testosterone use in combination and alone, sexual instruments of measurement). There is no data indicating severe short-term adverse effects, although long-term safety data is lacking. CONCLUSIONS: Despite having testosterone as a valuable tool, therapeutic strategies are lacking in the pharmacological field of HSDD/FSIAD. Neuroimaging studies could provide valuable information regarding the sexual desire substrate and suggest the potential application of already approved drugs for women with a good safety profile. The use of validated instruments for HSDD in postmenopausal women, considering the level of distress, is necessary to be able to draw robust conclusions on the evaluated treatments.

RESUMO

Rectal perforations due to topical treatments (enemas or foams) are unusual complications and they have been mostly reported in the use of barium enemas or in elderly patients with constipation. Very little has been reported about perforations secondary to topical treatment in patients with ulcerative colitis. We present the case of a patient with ulcerative colitis who suffered a rectal perforation complicated with a superinfected collection after the application of topical mesalazine foam.

RESUMO

Genomic data provides useful information for public health practice, particularly when combined with epidemiologic data. However, sampling bias is a concern because inferences from nonrandom data can be misleading. In March 2021, the Washington State Department of Health, USA, partnered with submitting and sequencing laboratories to establish sentinel surveillance for SARS-CoV-2 genomic data. We analyzed available genomic and epidemiologic data during presentinel and sentinel periods to assess representativeness and timeliness of availability. Genomic data during the presentinel period was largely unrepresentative of all COVID-19 cases. Data available during the sentinel period improved representativeness for age, death from COVID-19, outbreak association, long-term care facility-affiliated status, and geographic coverage; timeliness of data availability and captured viral diversity also improved. Hospitalized cases were underrepresented, indicating a need to increase inpatient sampling. Our analysis emphasizes the need to understand and quantify sampling bias in phylogenetic studies and continue evaluation and improvement of public health surveillance systems.

RESUMO

OBJECTIVE: HIV infection and malaria have been associated with different complications during pregnancy and delivery. HIV-positive pregnant women are at increased risk for all adverse outcomes of malaria during pregnancy. The main objective was to analyse the obstetric and perinatal consequences of malaria, HIV infection and HIV/malaria co-infection in pregnant women and newborns, which has been less well evaluated. METHODS: A cross-sectional study was carried out in the Maternity Service of the Provincial Hospital of Tete Mozambique, involving completion of a structured questionnaire that included demographic data, and information on the current pregnancy, delivery and the newborn. In total, 819 women (13-45 years old) in the immediate postpartum period were enrolled between 1 March and 31 October 2016. RESULTS: The overall prevalence of HIV and malaria, considered separately, in pregnant women was ~12% (103 women with HIV and 101 with malaria). Only one-fifth of HIV-infected women knew their HIV status before pregnancy. A significantly higher proportion of women with HIV attended four or more antenatal care visits than women without HIV. Caesarean section was less frequent in HIV patients, and peripartum urinary infection was more frequent than in seronegative women (13/103 [12.6%] vs. 34/716 [4.7%]). HIV/malaria co-infection were 17/819 (2%) and was significantly associated with the development of pre-eclampsia when HIV-infected patients received anti-retroviral treatment, and with an increase in urinary tract infections around delivery. With respect to the newborn, co-infection increased the frequency of early neonatal death, as well as neonatal asphyxia and jaundice. CONCLUSIONS: In Mozambique, the prevalence of malaria and HIV infection in women of childbearing age continues to be high and contributes additively to complications during pregnancy and childbirth, and in the newborn. Therefore, integrating HIV, malaria and reproductive health services is essential if maternal and foetal outcomes are to improve.

RESUMO

BACKGROUND: Plasmodium falciparum infection in pregnant women in sub-Saharan Africa is often asymptomatic. As these forms of malaria are often submicroscopic and difficult to diagnose by conventional methods (microscopy and/or rapid diagnostic test), diagnosis requires the use of molecular techniques such as polymerase chain reaction (PCR). This study analyses the prevalence of subclinical malaria and its association with adverse maternal and neonatal outcomes, a topic that has been scarcely evaluated in the literature. METHODS: A cross-sectional study was conducted using semi-nested multiplex PCR to assess the presence of P. falciparum in placental and peripheral blood of 232 parturient pregnant women at the Hospital Provincial de Tete, Mozambique between March 2017 and May 2019. Multivariate regressions were performed to assess the associations of maternal subclinical malaria with several maternal and neonatal outcomes after controlling for the presence of preeclampsia/eclampsia (PE/E) and HIV infection, as well as for other maternal and pregnancy characteristics. RESULTS: In total, 17.2% (n = 40) of the women studied had positive PCR for P. falciparum (7 in placental blood only, 3 in peripheral blood only). We found a significant association between subclinical malaria and a higher peripartum mortality risk, which persisted after controlling for maternal comorbidity and maternal and pregnancy characteristics (adjusted odds ratio: 3.50 [1.11-10.97]). In addition, PE/E and HIV infections were also significantly associated with several adverse maternal and neonatal outcomes. CONCLUSION: This study demonstrated the association of subclinical malaria, as well as of PE/E and HIV, in pregnant women with adverse maternal and neonatal outcomes. Therefore, molecular methods may be sensitive tools to identify asymptomatic infections that can reduce the impact on peripartum mortality and their contribution to sustained transmission of the parasite in endemic countries.

RESUMO

OBJECTIVES: Men and women living in rural communities of the United States (US) are less likely than those in urban or suburban communities to be up to date with cancer screenings. Delayed screening contributes to later stage at diagnosis and higher cancer mortality for individuals living in rural areas. These effects may be compounded in some rural subpopulations (e.g. migrant and seasonal farmworkers). This systematic review examines educational interventions aimed at increasing colorectal, breast, prostate, oral, and/or cervical cancer screening in the rural US, with special consideration for the farmworker subpopulation. DESIGN: Using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, our systematic literature review employed the following databases: Ovid MEDLINE, CINAHL Complete, Embase, and Web of Science. Search terms included, but were not limited to 'rural,' 'cancer screening,' 'farmworker,' and 'cancer prevention.' Eligible studies featured an educational intervention implemented in agricultural or rural US settings with a cancer screening behavioral outcome, male and/or female participants, and were published in English between 2002 and 2020. Article screening and data extraction were conducted by two independent reviewers. RESULTS: Twenty-six articles were eligible. Of the six studies focused on the farmworker population (n=2,732), 61.75% of participants reported Hispanic ethnicity. Of the sixteen studies on unspecified rural communities reporting participant race/ethnicity (n=10,442), 39.29% reported Black/African American race. Efficacious interventions included culturally-targeted educational materials, lay health advisors (LHAs), and components that addressed practical barriers (e.g. financial or logistical). CONCLUSION: Results demonstrate the value of LHAs and targeted education to increase screening for multiple cancer types in rural communities. Prospective research should incorporate and facilitate access to screening and provider-level and/or organizational-level interventions to increase overall impact.

RESUMO

Tuberculosis (TB), historically the most significant cause of human morbidity and mortality, has returned as the top infectious disease worldwide, under circumstances worsened by the COVID-19 pandemic's devastating effects on public health. Although Mycobacterium tuberculosis, the causal agent, has been known of for more than a century, the development of tools to control it has been largely neglected. With the advancement of nanotechnology, the possibility of engineering tools at the nanoscale creates unique opportunities to exploit any molecular type. However, little attention has been paid to one of the major attributes of the pathogen, represented by the atypical coat and its abundant lipids. In this review, an overview of the lipids encountered in M. tuberculosis and interest in exploiting them for the development of TB control tools are presented. Then, the amalgamation of nanotechnology with mycobacterial lipids from both reported and future works are discussed.

RESUMO

Oily sludge is a residue from the petroleum industry composed of a mixture of sand, water, metals, and high content of hydrocarbons (HCs). The heavy oily sludge used in this study originated from Colombian crude oil with high density and low American Petroleum Institute (API) gravity. The residual waste from heavy oil processing was subject to thermal and centrifugal extraction, resulting in heavy oily sludge with very high density and viscosity. Biodegradation of the total petroleum hydrocarbons (TPH) was tested in microcosms using several bioremediation approaches, including: biostimulation with bulking agents and nutrients, the surfactant Tween 80, and bioaugmentation. Select HC degrading bacteria were isolated based on their ability to grow and produce clear zones on different HCs. Degradation of TPH in the microcosms was monitored gravimetrically and with gas chromatography (GC). The TPH removal in all treatments ranged between 2 and 67%, regardless of the addition of microbial consortiums, amendments, or surfactants within the tested parameters. The results of this study demonstrated that bioremediation of heavy oily sludge presents greater challenges to achieve regulatory requirements. Additional physicochemical treatments analysis to remediate this recalcitrant material may be required to achieve a desirable degradation rate.

RESUMO

AIMS AND OBJECTIVES: The aim of this study was to assess the effect of the FreeStyle Libre device implantation in adult type 1 diabetics in a Health Area of Castilla La Mancha (Spain) during the COVID-19 pandemic. BACKGROUND: FreeStyle Libre is a so-called mHealth device that supports health care. During COVID-1 confinement, diabetic patients could have improved their glycaemic monitoring thanks to these devices, although health care in these patients may have been limited due to confinement. METHODS: A 12-month longitudinal study in which a total of 206 type I diabetics participated, belonging to a single health area. Sociodemographic and analytical data and the Self Care Inventory Revised questionnaire (SCI-R) were collected. STROBE checklist was followed. RESULTS: The analysis showed differences related to the use of the sensor. After the study period, patients obtained better levels of basal glucose, glycosylated haemoglobin, creatinine, cholesterol, triglycerides and LDL. In addition, a significant increase in the total score of the SCI-R questionnaire was observed after the use of the monitor (MD -7.77; 95% CI -10.43, -8.29). The same occurred with different SCI-R items such as diet (MD -2.995; 95% CI -3.24, -2.57), glucose determination (MD -3.21; 95% CI -3.52, -2.91), medication administration (MD -2.58; 95% CI -2.53, -1.96) and hypoglycaemic episodes (MD -1.07; 95% CI -1.21, -0.93). In the analysis by groups, worse values of glycosylated haemoglobin and adherence to treatment (p < .05) were observed in overweight/obese subjects versus those with normal weight after one year of study. CONCLUSION: The use of flash monitoring is related to better adherence to most of the recommended habits in diabetes. Nevertheless, there seems to be no relationship with an improvement in physical exercise and preventive aspects of diabetes. A good nursing intervention to support physical exercise and the use of mHealth devices could improve the control of diabetic patients. RELEVANCE TO CLINICAL PRACTICE: The use of this mHealth device has shown positive results and reduced complications. Despite less contact with healthcare facilities due to the pandemic, type 1 diabetic patients have improved their blood results and adherence after using the device for one year. Nursing staff should focus on promoting physical activity and routine disease care in type 1 diabetics.

RESUMO

BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic is dominated by variant viruses; the resulting impact on disease severity remains unclear. Using a retrospective cohort study, we assessed the hospitalization risk following infection with 7 severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants. METHODS: Our study includes individuals with positive SARS-CoV-2 reverse transcription polymerase chain reaction (RT-PCR) in the Washington Disease Reporting System with available viral genome data, from 1 December 2020 to 14 January 2022. The analysis was restricted to cases with specimens collected through sentinel surveillance. Using a Cox proportional hazards model with mixed effects, we estimated hazard ratios (HR) for hospitalization risk following infection with a variant, adjusting for age, sex, calendar week, and vaccination. RESULTS: In total, 58 848 cases were sequenced through sentinel surveillance, of which 1705 (2.9%) were hospitalized due to COVID-19. Higher hospitalization risk was found for infections with Gamma (HR 3.20, 95% confidence interval [CI] 2.40-4.26), Beta (HR 2.85, 95% CI 1.56-5.23), Delta (HR 2.28 95% CI 1.56-3.34), or Alpha (HR 1.64, 95% CI 1.29-2.07) compared to infections with ancestral lineages; Omicron (HR 0.92, 95% CI .56-1.52) showed no significant difference in risk. Following Alpha, Gamma, or Delta infection, unvaccinated patients show higher hospitalization risk, while vaccinated patients show no significant difference in risk, both compared to unvaccinated, ancestral lineage cases. Hospitalization risk following Omicron infection is lower with vaccination. CONCLUSIONS: Infection with Alpha, Gamma, or Delta results in a higher hospitalization risk, with vaccination attenuating that risk. Our findings support hospital preparedness, vaccination, and genomic surveillance.

RESUMO

BACKGROUND: The zoonotic simian parasite Plasmodium cynomolgi develops into replicating schizonts and dormant hypnozoites during the infection of hepatocytes and is used as a model organism to study relapsing malaria. The transcriptional profiling of P. cynomolgi liver stages was previously reported and revealed many important biological features of the parasite but left out the host response to malaria infection. METHODS: Previously published RNA sequencing data were used to quantify the expression of host genes in rhesus macaque hepatocytes infected with P. cynomolgi in comparison to either cells from uninfected samples or uninfected bystander cells. RESULTS: Although the dataset could not be used to resolve the transcriptional profile of hypnozoite-infected hepatocytes, it provided a snapshot of the host response to liver stage schizonts at 9-10 day post-infection and identified specific host pathways that are modulated during the exo-erythrocytic stage of P. cynomolgi. CONCLUSIONS: This study constitutes a valuable resource characterizing the hepatocyte response to P. cynomolgi infection and provides a framework to build on future research that aims at understanding hepatocyte-parasite interactions during relapsing malaria infection.

RESUMO

ABSTRACT: Children with refractory functional abdominal pain (FAP) experience functional disability and may utilize emergency department (ED) and/or inpatient services. Whether multidisciplinary programs which help care for children with refractory FAP affect acute healthcare utilization is unknown. A retrospective chart review of children initially evaluated by the outpatient Multidisciplinary Abdominal Pain Program (MAPP) from October 2016 to May 2019 was completed. Patient characteristics and number of ED visits and hospitalizations for abdominal pain in the year prior to versus year after MAPP evaluation were captured. Thirty-eight children (ages 9-17 years [median 13 years]) were included. The median number of ED visits/patient/year decreased from 1 (range: 0-7) to 0 (range: 0-3) (P < 0.0001). Seven (18%) children had been hospitalized and, in these children, the median number of hospitalizations/patient/year decreased from 1 (range: 1-5) to 0 (range: 0-1) (P < 0.05). These data suggest multidisciplinary outpatient intervention for refractory FAP is associated with significant decreases in acute healthcare utilization.

RESUMO

The glucocorticoid receptor is an important immunosuppressive drug target and metabolic regulator that acts as a ligand-gated transcription factor. Generally, GR's anti-inflammatory effects are attributed to the silencing of inflammatory genes, while its adverse effects are ascribed to the upregulation of metabolic targets. GR binding directly to DNA is proposed to activate, whereas GR tethering to pro-inflammatory transcription factors is thought to repress transcription. Using mice with a point mutation in GR's zinc finger, that still tether via protein-protein interactions while being unable to recognize DNA, we demonstrate that DNA binding is essential for both transcriptional activation and repression. Performing ChIP-Seq, RNA-Seq and proteomics under inflammatory conditions, we show that DNA recognition is required for the assembly of a functional co-regulator complex to mediate glucocorticoid responses. Our findings may contribute to the development of safer immunomodulators with fewer side effects.

RESUMO

BACKGROUND: The growing number of employed women has been associated with an increase in the prevalence of overweight and obesity in children. We sought to determine whether childhood overweight/obesity in Spain is associated with labour participation of mothers and fathers, and whether the identity of the main caregiver has an influence on child's weight and unhealthy behaviour. METHODS: We used microdata from the 2010 and 2014 Health Behaviour in School-Aged Children surveys performed in Spain (n = 32,694). Logistic and linear multi-level regression models were applied to assess the association between parental employment and children's self-reported weight status, accounting for school effects and controlling for socioeconomic factors. Separated binary models were also fitted for consumption of fruit, sweets, screen viewing and sedentarism. RESULTS: In most cases, the significant associations between children's weight and their parents' work status disappeared once the models were adjusted for family wealth and education. However, we found persistent associations for some groups. Girls under 13 years-old living in households where the mother was the only employed parent were more likely to be affected by obesity and to report a higher body mass index value. Children in this type of household were more likely to show unhealthy lifestyles related to diet and leisure time activities. CONCLUSIONS: Parents' socioeconomic characteristics had a protective effect on their children's risk of obesity. Unhealthy behaviours were observed in households with a non-working father and a working mother, although the link with obesity was limited to girls. Our results suggest the need for a more equally shared burden of caregiving.

RESUMO

The more restrictive regulations of pesticides in Europe have led to an increase in conservation biological control (CBC) research. However, little attention has been paid to the main determinants of Lobesia botrana parasitism. The Douro Demarcated Region landscape offers scope for the use of CBC. The study was conducted between 2002 and 2015 aiming at: (i) identifying parasitoids associated with L. botrana and evaluating their impact as biological control agents in each generation of the pest, and (ii) evaluating the effect of both the proportion of ecological infrastructures (EI) near the vineyards, and the impact of management practices (chemical treatments and ground cover) on the parasitism of L. botrana. A total of 3226 larvae/pupae of L. botrana were collected (15% were parasitized and 485 parasitoids emerged). A complex of 16 taxa of parasitoids was identified, the majority belonging to Hymenoptera. The most abundant were Elachertus sp. (Eulophidae), Campoplex capitator Aubert (Ichneumonidae), and Brachymeria tibialis (Walker) (Chalcididae), which represented 62.5, 12.6, and 12.0% of the total assemblage of parasitoids which emerged, respectively. The percentage of parasitism ranged from 0.0 to 61.5% (first generation), from 0.0 to 36.8% (second generation), and from 0.0 to 12.1% (third generation). Importantly, it was found that the parasitism rate was higher in vineyards with ground cover. In addition, EI in the area surrounding the vineyards produced a significant increase in parasitism. These results suggest potential for CBC of L. botrana if EI around vineyards, and ground cover with native perennial plants within vineyards, are encouraged.

RESUMO

BACKGROUND: Systemic lupus erythematosus (SLE) is an autoimmune multisystemic disease with a wide variety of clinical manifestations. One of its symptoms, associated to high morbidity, is serositis. Its prevalence ranges between 11% and 54%, and little is known about factors associated to this manifestation. The aim of this study is to determine the prevalence of serositis in SLE patients visited at the outpatient Lupus Unit of the Hospital del Mar and identify risk factors that can be used as predictors of this manifestation. METHODS: A retrospective case-control study was performed based on the review of 297 medical records of SLE patients. Twenty-eight patients were identified to have suffered serositis (cases) and were age- and sex-matched with 2 controls with SLE without serositis. RESULTS: The overall prevalence of serositis in our cohort was 9.42%, being higher in men than in women, 30% versus 7.9% (p = 0.001, 95% CI: 1.7-42.4%). In 40.7%, it was the first manifestation of the disease. When looking for serositis-associated factors, an association was found with anti-dsDNA antibodies measured by the Crithidia method (p = 0.016), and different measures of corticosteroids, where cases had required higher maximum doses and more pulses than controls throughout the disease, although this last correlation was lost when adjusting for confounding variables as nephritis and arthritis. Cases also received more mycophenolic acid (p = 0.021) and, marginally, more belimumab (p = 0.056). CONCLUSION: The overall prevalence of serositis was 9.42%, being significantly higher in men (30%). Therefore, male gender constitutes a risk factor for serositis, and almost one third of men will develop this manifestation, so greater awareness is required in SLE men. CrithidiaDNA+ was also identified as a risk factor, and it should be determined in all SLE patients. Cases significantly received more corticosteroid pulses and higher maximum doses in relation to other SLE severe manifestations, which could imply a more aggressive form of SLE in patients with serositis.

RESUMO

OBJECTIVE: Latino men who have sex with men (MSM) are disproportionately affected by HIV in the US and only half of Latinos diagnosed with HIV are virally suppressed. Little is known about the determinants of HIV care and treatment outcomes among Latinos. We used theories of intersectionality to assess the HIV testing, care and treatment experiences of gay Latino men living with HIV in a new immigrant destination. DESIGN: We conducted qualitative in-depth interviews with US and foreign-born gay Latino men living with HIV (n = 14) recruited through referrals from HIV care providers and case managers. We used Maxwell and Miller's theory of qualitative analysis to guide our approach to data analysis, integrating narrative techniques and thematic coding. We used theories of intersectionality - including both intersecting identities and structures - as an interpretive framework to understand participants' outcomes and experiences. RESULTS: All participants were engaged in HIV care at the time of the interviews. The mental health burden of diagnosis and managing life with HIV was a salient theme across all interviews. Most participants had experienced interruptions in their care due to both intersecting stigmatized identities (e.g. being gay, Latino, undocumented) and intersecting structures (healthcare, immigration policy, institutionalized homophobia). Undocumented participants directly connected their immigration status to their ability to get work, which then affected their retention in HIV care and treatment adherence. CONCLUSIONS: Examining the interplay between identities and structures provides a contextualized understanding of outcomes along the HIV care continuum among gay Latino men that goes beyond behavioral and cultural explanations. There is a need to assess long-term experiences of navigating HIV care and treatment given the intersecting structures of mobility, housing instability, and immigration policy.
