RESUMO
AIM: The aim of the study was to determine whether overcooling (temperature <33°C) during passive hypothermia when transporting neonates with perinatal asphyxia increased the risk of short-term neurological injury. METHODS: A retrospective observational study was performed. Newborns transferred to the LaCardio neonatal unit between January 2021 and April 2022 with moderate and severe perinatal asphyxia and who received passive hypothermia during transport were included. A temperature of <33°C was considered overcooling. A composite outcome of neurological injury was defined by the presence of abnormalities on brain magnetic resonance imaging, video telemetry, seizure before discharge or both. RESULTS: The study included 101 newborns. A total of 18 neonates had a temperature <33°C after transportation. Neurological injuries were present in 21.8% of the temperature <33°C group and 78.2% of the temperature ≥33°C group. Temperature <33°C at the end of transport (aOR 9.2, 95% CI 1.1-77.3) were associated with neurological injury before discharge from the unit. CONCLUSION: During transportation, overcooling in neonates with asphyxia increases the risk of neurological injury before discharge from the neonatal unit. It is important to qualify the transport team with adequate training and equipment for therapeutic hypothermia.

BACKGROUND: The Public Health Services at the Metropolitan Region (MR) of Chile have nine acute psychiatric beds per 100,000 inhabitants, under international recommendations. AIM: The present study will evaluate the resolution capacity of the main MR Psychiatric Emergency Room (PER), which may help assess the impact of the availability of acute beds in the MR. MATERIAL AND METHODS: A retrospective observational study of electronic patient records for all adult patients attending PER of the Psychiatric Institute "Dr. José Horwitz B." between 2017 and 2020 was analyzed. Crude and adjusted Incidence Rate Ratios were obtained for the indication of hospitalization, admissions, and those rejected due to lack of acute psychiatric beds. RESULTS: 90,464 attendances were evaluated on 41,541 patients, and hospitalization was indicated for 12.5% of them. Admissions were carried out in 59.5%, and 35.9% did not occur due to a lack of acute psychiatric beds. When comparing the adjusted Incidence Rates, only a higher hospitalization rate was observed for users from regions (IRR = 1,267; 95% CI: 1,11-1,44; p-value < 0.001) and during the first half of 2020 (IRR = 1.49; CI95%: 1.35-1.65; p-value < 0.001). CONCLUSIONS: The demand for psychiatric hospitalizations and the low availability of acute psychiatric beds in the MR probably have unsuspected consequences. The solution requires multilevel planning among all the actors involved.

BACKGROUND: Cannabis use among young people in Chile has increased significantly in the last years. There is a consistent link between cannabis and psychosis. AIM: To compare cannabis use in patients with a first episode of psychosis and healthy controls. MATERIAL AND METHODS: We included 74 patients aged 20 ± 3 years (78% males) admitted to hospital with a first episode of psychosis and a group of 60 healthy controls aged 23 ± 4 years (63% males). Cannabis consumption was assessed, including age of first time use and length of regular use. RESULTS: Patients with psychosis reported a non-significantly higher frequency of life-time cannabis use. Patients had longer periods of regular cannabis use compared with healthy subjects (Odds ratio [OR] 2.4; 95% confi-dence intervals [CI] 1.14-5.05). Patients also used cannabis for the first time at an earlier age (16 compared with 17 years, p < 0.0). The population attributable fraction for regular cannabis use associated with hospital admissions due to psychosis was 17.7% (95% CI 1.2-45.5%). CONCLUSIONS: Cannabis use is related to psychosis in this Chilean group of patients. This relationship is stronger in patients with early exposure to the drug and longer the regular use. One of every five admissions due to psychosis is associated with cannabis consumption. These data should influence cannabis legisla-tion and the public policies currently being discussed in Chile.

In the last few decades, molecular techniques and genetic modification have been used in genotype and phenotype studies of S. suis. Genomic modification of S. suis requires DNA acquisition and its stable insertion into the chromosome by allelic exchange. In this chapter, we described two techniques for the preparation of genomic constructs (cloning and overlapping extension PCR) and for DNA uptake (electroporation and transformation). The protocols are accompanied with examples. All described protocols were successful on our hands with the reference S. suis strain P1/7.

BACKGROUND: Psychosis is related to neurochemical changes in deep-brain nuclei, particularly suggesting dopamine dysfunctions. We used an magnetic resonance imaging-based technique called quantitative susceptibility mapping (QSM) to study these regions in psychosis. QSM quantifies magnetic susceptibility in the brain, which is associated with iron concentrations. Since iron is a cofactor in dopamine pathways and co-localizes with inhibitory neurons, differences in QSM could reflect changes in these processes. METHODS: We scanned 83 patients with first-episode psychosis and 64 healthy subjects. We reassessed 22 patients and 21 control subjects after 3 months. Mean susceptibility was measured in 6 deep-brain nuclei. Using linear mixed models, we analyzed the effect of case-control differences, region, age, gender, volume, framewise displacement (FD), treatment duration, dose, laterality, session, and psychotic symptoms on QSM. RESULTS: Patients showed a significant susceptibility reduction in the putamen and globus pallidus externa (GPe). Patients also showed a significant R2* reduction in GPe. Age, gender, FD, session, group, and region are significant predictor variables for QSM. Dose, treatment duration, and volume were not predictor variables of QSM. CONCLUSIONS: Reduction in QSM and R2* suggests a decreased iron concentration in the GPe of patients. Susceptibility reduction in putamen cannot be associated with iron changes. Since changes observed in putamen and GPe were not associated with symptoms, dose, and treatment duration, we hypothesize that susceptibility may be a trait marker rather than a state marker, but this must be verified with long-term studies.

Context: The relative importance of the control of different metabolic risk factors for the prevention of chronic kidney disease among patients with diabetes in real life conditions is insufficiently understood. Objective: We evaluated the effect of the achievement of glycated hemoglobin A1c (HbA1c), systolic blood pressure (SBP), and low-density lipoprotein cholesterol (LDLc) or non-high-density lipoprotein cholesterol (non-HDLc) goals (ABC goals) on the development of incident chronic kidney disease (iCKD) among patients with diabetes. Methods: In a nationwide registry of all individuals diagnosed with diabetes assisted by the health system in Colombia, we analyzed the association between baseline or sustained goal achievement and development of iCKD over a 4-year follow-up. iCKD was defined as a new occurrence of an estimated glomerular filtration rate less than 60â mL/min/1.73â m2, hemodialysis, peritoneal dialysis, or kidney transplant. Results: The study included 998 790 adults with diabetes (56% female, mean age 59). There were 125 626 cases of iCKD. After adjustment for multiple confounders, a baseline SBP less than 130â mm Hg (odds ratio [OR] 0.79 [0.78-0.80]) and a baseline HbA1c less than 7.0% (OR 0.86 [0.85-0.87]) were negatively associated with iCKD. Sustained achievement showed stronger negative associations with iCKD than just baseline achievement. Considering each goal separately, sustained non-HDLc less than 130â mg/dL had the strongest negative association with iCKD (OR 0.67 [0.65-0.69]). Patients who maintained the triple ABC goal over the entire follow-up had 32% (29-34) lower odds of developing CKD, 38% (34-42) if they additionally kept a normal body mass index (BMI). Sustained ABC control including a normal BMI was more strongly associated with a lower incidence of CKD in patients of Black race (OR 0.72 vs 0.89; P for interactionâ =â .002). Conclusion: At the country level, sustained achievement of ABC goals and most especially non-HDLc were associated with substantial reductions in iCKD.
RESUMO
Objective: The magnitude of the mortality benefit conferred by good integral metabolic control in diabetes in not sufficiently known, especially among Latin American patients. We prospectively studied the association between sustained control of blood glucose (HbA1c<7%), systolic blood pressure (SBP) (<130 mmHg) and LDL (LDLc, <100mg/dL) and non-HDL (non-HDLc, <130 mg/dL) cholesterol, and death from any cause among all adult patients with diagnosed diabetes in Colombia. Methods: We retrospectively analyzed data from a nationwide, centralized, mandatory registry of all patients with diagnosed diabetes assisted by the Colombian health system between July 1, 2015, and June 30, 2019. We estimated the associations of sustained achievement of each goal, and of the joint triple goal (HbA1c + SBP + LDLc) with all-cause death. Associations were assessed after adjustment for sex, age, race, insurance type and BMI in multivariable logistic models. Results: We studied 1 352 846 people with diabetes. Sustained SBP (OR 0.42 [0.41-0.43]), HbA1c (OR 0.25 [0.24-0.26]) and LDLc (OR 0.28 [0.27-0.29]) control had strong negative associations with death. Moreover, among the 5.4% of participants who achieved joint, sustained metabolic control, the OR for death was 0.19 (0.18-0.21). Importantly, the impact of sustained, joint metabolic control was significantly smaller for patients of black race compared to other races (OR 0.31 [0.23-0.43] versus 0.18 [0.17-0.20], p-value for interaction <0.001), mostly at the expense of a smaller impact of LDLc control. The results were similar across body-mass index categories. Conclusions: Sustained and simultaneous metabolic control was associated with remarkably lower odds of death.

AIMS: To assess the achievement of essential treatment goals among patients with diabetes in Colombia. METHODS: We analyzed data from a nationwide registry of all individuals with diagnosed diabetes, hypertension or CKD assisted by the health system. We explored the prevalence of treatment goals (HbA1c < 7% [<53 mmol/mol], systolic blood pressure (SBP) < 130 mmHg and LDLc < 100 mg/dL), and their variations by race and type of health insurance, between July 1, 2015, and June 30, 2019. RESULTS: We studied 1 352 846 patients with diagnosed diabetes. The prevalence of HbA1c < 7% (<53 mmol/mol) remained steady at 52%, systolic blood pressure (SBP) < 130 mmHg was also stable at 80-82%. Meanwhile, the prevalence of both LDLc < 100 mg/dL and non-HDLc < 130 mg/dL increased by 6 percentage points. Achievement of the triple HbA1c + SBP + LDLc goal was only 21.4% in 2015, increasing to 24.4% by 2019. Goal achievement was consistently lower among patients of black race, especially for HbA1c (5% lower than other races), but also for the SBP, LDLc and joint goals. Patients under third-party insurance reached better HbA1c, SBP, and LDLc control. CONCLUSIONS: Achievement of treatment goals of patients with diabetes in Colombia remains substantially low, despite improvements in LDLc control.

Previous studies have suggested that subjects participating in schizophrenia research are not representative of the demographics of the global population of people with schizophrenia, particularly in terms of gender and geographical location. We here explored if this has evolved throughout the decades, examining changes in geographical location, gender and age of participants in studies of schizophrenia published in the last 50 years. We examined this using a meta-analytical approach on an existing database including over 3,000 studies collated for another project. We found that the proportion of studies and participants from low-and-middle income countries has significantly increased over time, with considerable input from studies from China. However, it is still low when compared to the global population they represent. Women have been historically under-represented in studies, and still are in high-income countries. However, a significantly higher proportion of female participants have been included in studies over time. The age of participants included has not changed significantly over time. Overall, there have been improvements in the geographical and gender representation of people with schizophrenia. However, there is still a long way to go so research can be representative of the global population of people with schizophrenia, particularly in geographical terms.

BACKGROUND: Educational attainment is associated with wellbeing and health, but patients with schizophrenia achieve lower levels of education than people without. Several effective interventions can ameliorate this situation. However, the magnitude of the education gap in schizophrenia and its change over time are unclear. We aimed to reconstruct the trajectories of educational attainment in patients with schizophrenia and, if reported, their healthy comparator controls. METHODS: We did a systematic review and meta-analysis including all studies reporting on patients with schizophrenia (of mean age ≥18 years) and describing the number of years of education of the participants, with or without healthy controls. There were no other design constraints on studies. We excluded studies that included only patients with other schizophrenia spectrum disorders and studies that did not specify the number of years of education of the participants. 22 reviewers participated in retrieving data from a search in PubMed and PsycINFO (Jan 1, 1970, to Nov 24, 2020). We estimated the birth date of participants from their mean age and publication date, and meta-analysed these data using random-effects models, focusing on educational attainment, the education gap, and changes over time. The primary outcome was years of education. The protocol was registered on PROSPERO (CRD42020220546). FINDINGS: From 32â593 initial references, we included 3321 studies reporting on 318â632 patients alongside 138â675 healthy controls (170â941 women and 275â821 men from studies describing sex or gender; data on ethnicity were not collected). Patients' educational attainment increased over time, mirroring that of controls. However, patients with schizophrenia in high-income countries had 19 months less education than controls (-1·59 years, 95% CI -1·66 to -1·53; p<0·0001), which is equivalent to a Cohen's d of -0·56 (95% CI -0·58 to -0·54) and implies an odds ratio of 2·58 for not completing 12 years of education (ie, not completing secondary education) for patients compared with controls. This gap remained stable throughout the decades; the rate of change in number of total years of education in time was not significant (annual change: 0·0047 years, 95% CI -0·0005 to 0·0099; p=0·078). For patients in low-income and middle-income countries, the education gap was significantly smaller than in high-income countries (smaller by 0·72 years, 0·85 to 0·59; p<0·0001), yet there was evidence that this gap was widening over the years, approaching that of high-income countries (annual change: -0·024 years, -0·037 to -0·011; p=0·0002). INTERPRETATION: Patients with schizophrenia have faced persistent inequality in educational attainment in the last century, despite advances in psychosocial and pharmacological treatment. Reducing this gap should become a priority to improve their functional outcomes.

Diabetes is a highly prevalent disease with complications that impact most bodily systems. However, the impact of diabetes on bone health is frequently ignored or underestimated. Both type 1 (T1D) and type 2 diabetes (T2D) are associated with a higher risk of fractures, albeit through different mechanisms. T1D is characterized by near total insulinopenia, which affects the anabolic tone of bone and results in reduced bone mineral density (BMD). Meanwhile, patients with T2D have normal or high BMD, but carry an increased risk of fractures due to alterations of bone microarchitecture and a local humoral environment that stimulates osteoclast activity. Chronic hyperglycemia induces non-enzymatic glycation of collagen in both types of diabetes. Epidemiological evidence confirms a largely increased fracture risk in T1D and T2D, but also that it can be substantially reduced by opportune monitoring of fracture risk and appropriate treatment of both diabetes itself and osteopenia or osteoporosis if they are present. In this review, we summarize the mechanistic, epidemiological, and clinical evidence that links diabetes and bone fragility, and describe the impact of available diabetes treatments on bone health.
RESUMO
INTRODUCTION: Little is known about predictors of clinical response to clozapine treatment in treatment-resistant psychosis. Most published cohorts are small, providing inconsistent results. We aimed to identify baseline clinical predictors of future clinical response in patients who initiate clozapine treatment, mainly focusing on the effect of age, duration of illness, baseline clinical symptoms and homelessness. METHODOLOGY: Retrospective cohort of patients with treatment-resistant schizophrenia, aged between 15 and 60â¯years, that initiated clozapine between 2014 and 2017. Sociodemographic characteristics, years from illness diagnosis, and clinical presentation before the initiation of clozapine were collected and analyzed. All-cause discontinuation at two years follow-up was used as the primary measure of clozapine response. RESULTS: 261 patients were included with a median age at illness diagnosis of 23â¯years old (IQR 19-29) and a median age at clozapine initiation of 25 (IQR: 21-33). 72.33% (183/253) continued clozapine after two years follow-up. Being homeless was associated to higher clozapine non-adherence, with an OR of 2.78 (95%CI 1.051-7.38) (pâ¯=â¯0.039, controlled by gender). Older age at clozapine initiation and longer delay from first schizophrenia diagnosis to clozapine initiation were also associated with higher clozapine non-adherence, with each year increasing the odds of discontinuation by 1.043 (95%CI 1.02-1.07; pâ¯=â¯0.001) and OR 1.092 (95%CI 1.01-1.18;pâ¯=â¯0.032) respectively. CONCLUSION: Starting clozapine in younger patients or shortly after schizophrenia diagnosis were associated with better adherence.

Molecular typing of bacterial isolates provides a powerful approach for distinguishing Mycobacterium bovis (M. bovis) genotypes. It is known that M. bovis strain virulence plays a role in prevalence and spread of the disease, suggesting that strain virulence and prevailing genotypes are associated. However, it is not well understood whether strain virulence correlates with particular genotypes. In this study, we assessed the in vitro intracellular growth of 18 M. bovis isolates in bovine macrophages as an indicator of bacterial virulence and sought a relationship with the genotype identified by spoligotyping. We found 14 different spoligotypes-11 were already known and three spoligotypes had never been reported before. We identified 2 clusters that were phylogenetically related, containing 10 and 6 strains, respectively, and 2 orphan strains. Intracellular growth and phagocytic rates of 18 M. bovis strains were heterogeneous. Our results suggest that M. bovis intracellular growth and phagocytosis are independent of the bacterial lineage identified by spoligotyping.
RESUMO
Tuberculosis (TB) represents a barrier for free trade of livestock between Mexico and the United States of America (US). In spite of efforts from Mexico to export TB-free animals, some of those found with TB lesions in slaughterhouses in the US are traced back to that country. Therefore, the purpose of this study was to determine, through molecular epidemiology, the most probable source of infection for cattle found with TB lesions in the US. Ninety M. bovis isolates, 50 from Mexico obtained from cattle in 8 different states, and 40 from the US from cattle, deer, elk and feral pigs from 7 different states were included in the study. All samples were analyzed in both laboratories, Mexico and the US, following the same protocol for molecular analysis by spoligotyping. Twenty-seven clusters, ranging from 1 to 18 genetically similar strains were found. Some clustering by country was observed, strains from cattle and deer in Michigan in the US fell into the same cluster, suggesting transmission between species. These results, combined with epidemiological information suggest that despite of the possibility that some animals with lesions in the US come from Mexico as false negatives, the US has its own source of infection, must probably in dairy cattle and wildlife. Genetic diversity of isolates from Mexico was larger than that in the US, which could be a consequence of the endemic status of the disease and the indiscriminate movement of animals between regions.

OBJECTIVE: The purpose of the study was to determine the role of bovine TB in cases of human TB. MATERIAL AND METHODS: Two-hundred and fifty-five samples from symptomatic patients were included in the study. All samples were cultured in Stonebrink and Lowënstein-Jensen media and analyzed using a nested PCRMPB70. The molecular analysis was performed by spoligotyping. RESULTS: From 255 samples, 74 were PCR-positive and 20 were culture-positive. From 94 samples positive to PCR or to isolation, 66 (70%) showed a spoligotype compatible with M. tuberculosis, and 13 (13.8%) with M. bovis. Four fingerprints of M. bovis from humans were identical to the fingerprints of M. bovis from cattle in the same region. CONCLUSIONS: Our study shows that M. bovis plays an important role in the epidemiology of TB in humans and that TB in cattle represents a risk to public health.

Actualmente, en Chile se ha evidenciado un aumento de la población vegetariana, sin embargo, existen escasos datos sociodemográficos, por lo cual, el objetivo del presente estudio es caracterizar, según antecedentes sociodemográficos y alimentarios a personas vegetarianas chilenas en el año 2022. Se utilizó el paradigma cuantitativo y el diseño metodológico fue no experimental, descriptivo, exploratorio de corte transversal. Se aplicó una encuesta de caracterización mediante Google Forms a 504 personas y para el análisis de la información se utilizó el programa SPSS v. 24. El 85,7% declaró ser de género femenino, la edad promedio fue 26,3 ± 5,7 años, 45,5% de los encuestados se declararon ovolactovegetarianos, seguido por vegetarianos estrictos (38,7%) y la principal motivación fue principios animalistas (68,7%). El 87,8% cursó educación superior y el 36,5% correspondió al área de salud. El principal motivo de asistencia al nutricionista fue el asesoramiento con un 80%. Se destacó que la población vegetariana consideró que es fundamental la asistencia a un profesional nutricionista para practicar este estilo de vida de forma óptima, por lo que es fundamental que los profesionales de salud se involucren en conocer a esta población, con el objetivo de otorgar una atención más cercana e integral. Finalmente, la presente investigación corresponde al primer estudio que permite caracterizar a la población vegetariana en Chile.
Currently, in Chile there has been an increase in the vegetarian population; however, there are few sociodemographic data, therefore, the objective of this study is to characterise, according to sociodemographic and dietary background, Chilean vegetarians in the year 2022. The quantitative paradigm was used and the methodological design was non-experimental, descriptive, exploratory cross-section. A characterisation survey was applied using Google Forms to 504 people and SPSS v. 24. 85.7% declared to be female, the average age was 26.3 ± 5.7 years, 45.5% of those surveyed declared themselves lacto-ovo vegetarians, followed by strict vegetarians (38.7%) and the main motivation was animalistic principles (68.7%). 87.8% attended higher education and 36.5% corresponded to the health area. The main reason for helping the nutritionist was the advice with 80%. It was highlighted that the vegetarian population considered that it is essential to assist a professional nutritionist in practising this lifestyle optimally, so it is essential that health professionals get involved in getting to know this population, with the aim of providing closer and more comprehensive care. Finally, this research corresponds to the first study that allows characterising the vegetarian population in Chile.
RESUMO
INTRODUCCIÓN: Los Servicios de Salud Públicos de la Región Metropolitana (RM) cuentan con 9 camas psiquiátricas de corta estadía por 100.000 habitantes adultos, por debajo de las recomendaciones internacionales. OBJETIVO: El presente estudio evaluará la capacidad de resolución del principal Servicio de Urgencias Psiquiátricas de la RM lo que puede ser de utilidad para evaluar el impacto de la disponibilidad de camas de corta estadía en la RM. MATERIALES Y MÉTODO: Se realizó un estudio observacional retrospectivo de todas las atenciones realizadas en el Servicio de Urgencias del Instituto Psiquiátrico "Dr. José Horwitz B." entre los años 2017 y 2020 y las indicaciones de hospitalización y su resolución. Se obtuvieron Razones de Tasas de Incidencia crudas y ajustadas para la indicación de hospitalización, las efectuadas y aquellas rechazadas por falta de vacantes. RESULTADOS: Se realizaron 90.464 atenciones a 41.541 usuarios y se indicó la hospitalización al 12,5% de ellas. La hospitalización se efectúa en el 59,5% de las atenciones y 35,9% no se pueden realizar por falta de vacantes. Al comparar las Tasas de Incidencia ajustadas se observó solamente una mayor tasa de hospitalización efectuada para los usuarios de regiones (IRR = 1,27; IC95%: 1,11-1,44; valor-p < 0,001) y durante el primer semestre de 2020 (IRR = 1,49; IC95%: 1,35-1,65; valor-p < 0,001). CONCLUSIONES: La evidente demanda por las hospitalizaciones psiquiátricas y la baja disponibilidad de camas de corta estadía en la Región Metropolitana probablemente tiene consecuencias insospechadas. Su abordaje es un desafío que requiere de una planificación multinivel entre todos los actores involucrados.
BACKGROUND: The Public Health Services at the Metropolitan Region (MR) of Chile have nine acute psychiatric beds per 100,000 inhabitants, under international recommendations. AIM: The present study will evaluate the resolution capacity of the main MR Psychiatric Emergency Room (PER), which may help assess the impact of the availability of acute beds in the MR. MATERIAL AND METHODS: A retrospective observational study of electronic patient records for all adult patients attending PER of the Psychiatric Institute "Dr. José Horwitz B." between 2017 and 2020 was analyzed. Crude and adjusted Incidence Rate Ratios were obtained for the indication of hospitalization, admissions, and those rejected due to lack of acute psychiatric beds. RESULTS: 90,464 attendances were evaluated on 41,541 patients, and hospitalization was indicated for 12.5% of them. Admissions were carried out in 59.5%, and 35.9% did not occur due to a lack of acute psychiatric beds. When comparing the adjusted Incidence Rates, only a higher hospitalization rate was observed for users from regions (IRR = 1,267; 95% CI: 1,11-1,44; p-value < 0.001) and during the first half of 2020 (IRR = 1.49; CI95%: 1.35-1.65; p-value < 0.001). CONCLUSIONS: The demand for psychiatric hospitalizations and the low availability of acute psychiatric beds in the MR probably have unsuspected consequences. The solution requires multilevel planning among all the actors involved.

Polymorphism of the PE domain of PE/PE_PGRS sequences was studied in Mycobacterium bovis isolates from different Mexican states. Samples were analyzed by spolygotyping and RFLP using IS6110 and a 235-bp fragment of the PE domain of PE/PE_PGRS as probes. With the PE probe, three different genotypes were observed, one being predominant in all states. These results confirm the high conservation of the PE domain and suggests a potential role for PE sequence as a stable genetic marker for bovine tuberculosis.

Bacterial vaginosis is a common reproductive infection in which commensal vaginal lactobacilli are displaced by a mixed population of pathogenic bacteria. Bacterial vaginosis increases susceptibility to HIV, and it has been suggested that host innate immune responses to pathogenic bacteria contribute to enhanced infection, yet the cellular mechanisms mediating the increased HIV susceptibility remain uncharacterized. We evaluated the HIV-enhancing effects of bacterial vaginosis by inoculating endocervical epithelia with Atopobium vaginae, a bacterial vaginosis-associated bacteria, and assaying secreted factors for HIV-enhancing activity. When epithelia and A. vaginae were cocultured, we observed increased HIV-enhancing activity mediated by secreted low molecular weight factors. From this complex mixture we identified several upregulated host proteins, which functioned in combination to enhance HIV infection. These studies suggest that the host immune response to bacterial vaginosis-associated bacteria results in the release of HIV-enhancing factors. The combined activity of bacterial vaginosis-induced proteins likely mediates HIV enhancement.
