RESUMEN

BACKGROUND: Pre-exposure prophylaxis (PrEP), condom use, post-exposure prophylaxis (PEP), and sexual partner reduction help to prevent HIV acquisition but have low uptake among young people. We aimed to assess the efficacy of automated text messaging and monitoring, online peer support, and strengths-based telehealth coaching to improve uptake of and adherence to PrEP, condom use, and PEP among adolescents aged 12-24 years at risk of HIV acquisition in Los Angeles, CA, USA, and New Orleans, LA, USA. METHODS: We conducted a four-arm randomised controlled factorial trial, assessing interventions designed to support uptake and adherence of HIV prevention options (ie, PrEP, PEP, condom use, and sexual partner reduction). We recruited young people aged 12-24 years who were at risk of HIV acquisition from 13 community-based organisations, adolescent medicine clinics, and organisations serving people who are unstably housed, people who were previously incarcerated, and other vulnerable young people, and through dating apps, peer referrals, and social venues and events in Los Angeles, CA, USA, and New Orleans, LA, USA. Young people who tested seronegative and reported being gay, bisexual, or other men who have sex with men, transgender men or women, or gender diverse (eg. non-binary or genderqueer) were eligible for inclusion. Participants were randomly assigned to one of four intervention groups in a factorial design: automated text messaging and monitoring (AMMI) only, AMMI plus peer support via private social media, AMMI plus strengths-based telehealth coaching by near-peer paraprofessionals, or AMMI plus peer support and coaching. Assignment was further stratified by race or ethnicity and sexual orientation within each interviewer's group of participants. Participants were masked to intervention assignment until after baseline interviews when offered their randomly assigned intervention, and interviewers were masked throughout the study. Interventions were available throughout the 24-month follow-up period, and participants completed baseline and follow-up assessments, including rapid diagnostic tests for sexually transmitted infections, HIV, and substance use, at 4-month intervals over 24 months. The primary outcomes were uptake and adherence to HIV prevention options over 24 months, measured by self-reported PrEP use and adherence, consistent condom use with all partners, PEP prescription and adherence, and number of sexual partners in participants with at least one follow-up. We used Bayesian generalised linear modelling to assess changes in outcomes over time comparing the four study groups. This study is registered with ClinicalTrials.gov (NCT03134833) and is completed. FINDINGS: We screened 2314 adolescents beginning May 1, 2017, to enrol 1037 participants (45%) aged 16-24 years between May 6, 2017, and Aug 30, 2019, of whom 895 (86%) had follow-up assessments and were included in the analytical sample (313 assigned to AMMI only, 205 assigned to AMMI plus peer support, 196 assigned to AMMI plus coaching, and 181 assigned to AMMI plus peer support and coaching). Follow-up was completed on Nov 8, 2021. Participants were diverse in race and ethnicity (362 [40%] Black or African American, 257 [29%] Latinx or Hispanic, 184 [21%] White, and 53 [6%] Asian or Pacific Islander) and other sociodemographic factors. At baseline, 591 (66%) participants reported anal sex without a condom in the past 12 months. PrEP use matched that in young people nationally, with 101 (11%) participants reporting current PrEP use at baseline, increasing at 4 months to 132 (15%) and continuing to increase in the AMMI plus peer support and coaching group (odds ratio 2·31, 95% CI 1·28-4·14 vs AMMI control). There was no evidence for intervention effect on condom use, PEP use (ie, prescription or adherence), PrEP adherence, or sexual partner numbers. No unanticipated or study-related adverse events occurred. INTERPRETATION: Results are consistent with hypothesised synergistic intervention effects of evidence-based functions of informational, motivational, and reminder messaging; peer support for HIV prevention; and strengths-based, goal-focused, and problem-solving telehealth coaching delivered by near-peer paraprofessionals. These core functions could be flexibly scaled via combinations of technology platforms and front-line or telehealth HIV prevention workers.

RESUMEN

BACKGROUND: To slow the spread of the COVID-19 virus, governments across the globe instituted stay-at-home orders leading to increased stress and social isolation. Not surprisingly, alcohol sales increased during this period. While most studies primarily focused on alcohol consumption among college students or adults, this study investigates alcohol misuse among marginalized youth in the USA. We examined risk factors associated with hazardous alcohol use and binge drinking including risk behaviors, life stressors and demographic characteristics. METHODS: In October 2020, youth living with or at high risk for acquiring human immunodeficiency virus (HIV), participating in community-based research to improve HIV prevention and care, were invited to complete an online survey to assess the impact of the stay-at-home orders on multiple aspects of their daily life. RESULTS: Respondents (n = 478) were on average 23 years old; cisgender (84%), not-heterosexual (86.6%), Latino or Black/African American (73%) and assigned male at birth (83%); 52% reported being employed and 14% reported living with HIV. White participants and those who use drugs had higher odds of hazardous alcohol use and binge drinking, compared with other race categories and non-drug users, respectively. CONCLUSION: Contrary to findings from adult studies, we did not observe an increase in hazardous or binge drinking among youth at risk for HIV. Hazardous alcohol use and binge drinking was more likely among White participants, those who use drugs and those who were hazardous/binge drinkers prior to the COVID-19 lockdown, which points to the importance of identifying and treating youth who misuse alcohol early to prevent future alcohol misuse.

RESUMEN

OBJECTIVES: HIV scholars and practitioners have worked to expand strategies for prevention among marginalised populations who are disproportionately impacted by the epidemic, such as racial minority men who have sex with men (MSM). Given this urgency, the objective of this study was to assess interest in biomedical prevention strategies. METHODS: This exploratory and cross-sectional study investigated interest in four biomedical prevention tools-rectal douche, dissolvable implant, removable implant and injection-among a racially diverse sample of MSM from the Northeast Corridor region between Philadelphia and Trenton. Data were collected as part of screening for Connecting Latinos en Pareja, a couples-based HIV prevention intervention for Latino MSM and their partners. RESULTS: A total of 381 individuals participated in the screener and provided information about their interest in bio tools. Approximately 26% of participants identified as black, 28% as white and 42% as 'other' or multiracial; 49% identified as Latino. Majority (54%) reported some form of child sexual abuse. Of the participants who reported being in a primary relationship (n=217), two-thirds reported unprotected anal sex within that relationship over the past 90 days (n=138, 64%) and approximately half (n=117, 54%) reported unprotected anal sex outside of the relationship in this period. Majority of participants reported interest in all bio tools assessed, including dissolvable implants (60%), removable implants (64%), rectal douching (79%) and injection (79%). Although interest in bio tools was broadly unassociated with demographics and sexual risk behaviours, analyses revealed significant associations between reports of child sexual abuse and interest in implant and injection methods. CONCLUSIONS: The authors recommend investing in these prevention methods, particularly rectal douching and injection, as a means of preventing HIV among racial minority MSM. Given the interest in biomedical prevention tools, future studies should explore potential strategies for adherence.

RESUMEN

BACKGROUND: Youth continue to have the poorest outcomes along the HIV prevention and care continua. Motivational Interviewing (MI) may promote behavior change and reduce perceived stigma, but providers often demonstrate inadequate MI competence. This study tested Tailored Motivational Interviewing (TMI), a set of implementation strategies designed to improve MI competence in youth HIV providers. SETTING: Ten HIV clinics in the Adolescent Trials Network for HIV/AIDS Interventions. METHODS: In a stepped wedge design, 10 clinics (N = 151 providers) were randomized in 5 clusters every 3 months to receive TMI for a 12-month implementation period. Sites were rerandomized within each cluster to receive communities of practice guidance with or without internal facilitator support in the sustainment period. Standard patient assessments were coded every 3 months for 36 months. RESULTS: Nesting was addressed using mixed-effects regression models, with random effects for providers and sites. TMI resulted in significantly improved MI competence over baseline. Despite small reductions in competence in the sustainment window, competence was still significantly improved over baseline, with no difference between the 2 sustainment conditions. CONCLUSIONS: TMI may be an important tool to capacitate the HIV HealthForce to end the HIV epidemic in young people.

RESUMEN

Las dificultades socio-comunicativas que presentan los/as niños/as con trastorno del espectro autista (TEA), y las barreras del entorno sanitario, pueden complicar las pruebas diagnósticas y las intervenciones sanitarias hasta el punto de no poder realizarse. Pueden darse momentos muy complicados para estos niños/as y sus familias, que son vividos con gran ansiedad generándoles gran hostilidad hacia el entorno sanitario. A su vez, los profesionales se ven desbordados e impotentes ante estas situaciones, aumentando los recursos humanos y el tiempo necesarios para atenderles. El personal de Enfermería tiene un papel fundamental en la identificación de las dificultades y barreras, tanto las que presentan los/as niños/as y sus familias, como las del propio personal sanitario implicado, pudiendo actuar como facilitadores desde el primer momento.El Servicio de Neurofisiología realiza electroencefalogramas (EEG) a pacientes con TEA, ya que la epilepsia es un problema frecuentemente asociado al mismo. Las dificultades para efectuar con éxito la prueba han llevado a la creación del programa ADAPTATEA, cuyo objetivo general es mejorar la calidad de la atención y conseguir realizar el EEG en las mejores condiciones posibles, llevando a cabo las adaptaciones sanitarias necesarias. Se basa en el empleo de pictogramas y material audiovisual cuyo objetivo es anticipar al niño o niña y familia lo que se les va a hacer, transformando la prueba en algo más cercano y cotidiano para ellos. Además, propone recomendaciones para la preparación, ejecución de la prueba, y para el mejor manejo de las conductas desadaptativas del niño/a cuando acude al hospital.(AU)


The socio-communicative difficulties presented by children with autism spectrum disorder (ASD) and the healthcare environment barriers can complicate diagnostic tests and healthcare interventions even to the point where these cannot be performed. These can lead to very difficult times for these children and their families, experienced with high anxiety and generating major hostility towards the healthcare environment. At the same time, professionals will feel overwhelmed and powerless when faced with these situations, which require an increase in human resources and time. The Nursing staff plays an essential role in the detection of these difficulties and barriers, presented both by children and their families and by the healthcare staff involved, and they can act as facilitators since the first minute.The Neurophysiology Unit performs electroencephalograms (EEG) to ASD patients, because epilepsy is a problem often associated with this disorder. The difficulties to perform this test successfully have led to the creation of the ADAPTATEA program, with the overall objective to improve the quality of care and being able to perform the EEG in the best possible conditions, by conducting the healthcare adaptations required. This is based on the use of pictograms and audiovisual materials targeted to explaining the child and his/her family what will be done and transforming the test into something closer and more common to them. Besides, it proposes recommendations for the preparation and performance of the test, and for the best management of the maladaptive behaviours of the child when attending hospital.(AU)

RESUMEN

Coronavirus disease 2019 (COVID-19) has increased the risk of developing severe acute respiratory distress syndrome and subsequent moderate to severe laryngotracheal stenoses (LSTs) with an early presentation that occurs between two and three months after SARS-CoV-2 infection. We present a series of 12 cases of LST following SARS-CoV-2 infection. Dense lymphocyte infiltration with multinuclear giant cell granulomas was found on biopsy with intranuclear inclusions, suggestive of viral cytopathic effects in one case and intravascular fibrin thrombi with perivascular mononuclear infiltrate of CD3 + T lymphocytes. We present the largest and only series that describes clinical and histopathological characteristics of LTS and the management and outcomes after early laryngotracheal reconstruction in the context of the SARS-CoV-2 outbreak.

RESUMEN

Sexual and gender minority (SGM) and racial or ethnic minority youth at-risk for or living with HIV may have higher risk of SARS-CoV-2 infection. However, there are few data on vaccine hesitancy/acceptance and COVID-19 self-protective behaviors among this population. Youth aged 15-24 years (n = 440), predominantly African American and Latine (73%, n = 320) SGM, from Los Angeles and New Orleans reported their vaccine attitudes and COVID-19 and HIV preventive behaviors in October 2020. Latent class analyses categorized individuals into groups based on their vaccine attitudes and preventive behaviors. Relationships between these groups and other factors were analyzed using Fisher's exact tests, ANOVA, and logistic regression. Most youth had accepting vaccine attitudes (70.2%, n = 309), with 20.7% hesitant (n = 91), and 9.1% resistant (n = 40). SGM and African Americans were significantly less accepting than their cis-gender and heterosexual peers. About two-thirds (63.2%, n = 278) of the respondents reported consistent COVID-19 self-protective behaviors. Youth with pro-vaccine attitudes were most consistently self-protective; however, only 54.4% (n= 168/309) intended to take a COVID-19 vaccine. Homelessness history, race, and sexual orientation were associated with vaccine attitudes. Accepting vaccine attitudes and consistent COVID-19 self-protective behaviors were closely related. COVID-19 attitudes/behaviors were not associated with HIV risk and only loosely associated with SARS-CoV-2 vaccine intentions.

RESUMEN

Climate proxy data are required for improved understanding of climate variability and change in the pre-instrumental period. We present the first international initiative to compile and share information on pro pluvia rogation ceremonies, which is a well-studied proxy of agricultural drought. Currently, the database has more than 3500 dates of celebration of rogation ceremonies, providing information for 153 locations across 11 countries spanning the period from 1333 to 1949. This product provides data for better understanding of the pre-instrumental drought variability, validating natural proxies and model simulations, and multi-proxy rainfall reconstructions, amongst other climatic exercises. The database is freely available and can be easily accessed and visualized via http://inpro.unizar.es/ .

RESUMEN

BACKGROUND: HIV continues to disproportionately impact sexual and gender minority youth (SGMY) in the United States. Public health efforts have increasingly focused on developing efficacious interventions to curb the spread of HIV among SGMY and help those living with HIV achieve and sustain viral suppression. However, recruiting and engaging SGMY in prevention and care interventions is challenging. OBJECTIVE: During the past decade, gay dating apps have quickly emerged as popular web-based spaces in which SGMY congregate. Although the recruitment of SGMY through these apps has been commonly reported, advertisement is the typical modality used, and direct recruitment approaches are not adequately described. This study aims to describe the process for developing a direct recruitment protocol for use in gay dating apps. METHODS: The Adolescent Medicine Trials Network Comprehensive Adolescent Research and Engagement Studies is a community-based research program consisting of 3 interrelated studies testing scalable behavioral interventions to improve HIV prevention and care engagement among youth aged 12-24 years in Los Angeles and New Orleans. To supplement our in-person recruitment approaches for Comprehensive Adolescent Research and Engagement Studies, the New Orleans site formed a gay dating app recruitment team. In April 2018, the team developed a loosely structured protocol that included study-specific profiles and sample language to guide initial recruitment efforts. Two self-identified Black, gay cisgender male field recruiters field-tested the protocol on the popular gay dating app Jack'd. During the field test, the recruitment team met weekly to discuss the recruiters' experiences and user reactions. For example, we learned the importance of addressing concerns about study legitimacy and identifying appropriate ways to describe the study. We iteratively incorporated these lessons learned into the final protocol and developed a training program and tracking procedures before moving to full-scale implementation at both sites. RESULTS: Adhering to this protocol yielded 162 enrollments in New Orleans (332 total enrollments across the two sites) throughout the recruitment period (April 2018 to August 2019). Most of these participants were sexual minority cisgender males (91%), and the remainder were identified as members of gender minority groups. We outlined step-by-step instructions on training staff, engaging users, and scheduling and tracking recruitment activities. CONCLUSIONS: This paper provides a practical guide for researchers and community-based providers to implement a gay dating app recruitment protocol. Our experience indicates that gay dating app recruitment is feasible and fruitful when the staff members are knowledgeable, flexible, honest, and respectful to the user. Perhaps the most salient lesson we learned in approaching gay dating app users is the importance of setting clear and transparent intentions without judgment. As gay dating apps continue to increase in popularity, researchers need to stay vigilant to changing formats and develop systematic approaches to harness their potential as invaluable recruitment strategies for SGMY.

RESUMEN

Although the frequency of pregnancy in women on chronic dialysis is extremely low, it is associated with severe maternal and perinatal morbidity and mortality. This situation represents a challenge for the therapeutic team, which requires multidisciplinary management, as well as measures to adequate dialysis treatment. Such efforts include increasing the time and frequency of dialysis session, maintaining low uremia levels and ensuring hemodynamic stability by avoiding intra-treatment arterial hypotension and hydro electrolytic fluctuations. Regarding the dialysis modality, literature makes references to hemodialysis or peritoneal dialysis in pregnancy women, but little is known about the of high volume online hemodiafiltration (HVHDF) as well as the appropriate type of replacement fluid (pre-dilution or post-dilution). We present two cases of patients who were pregnant while being treated with HVHDF modality and had a favorable evolution, where the decision to continue with this dialysis modality was motivated by a best hemodynamic stability and the highest clearance of all types of uremic toxins offered by HVHDF.

RESUMEN

This paper presents experimental results from the application of a data-based model predictive decision support system to drug inventory management in the pharmacy of a mid-size hospital in Spain. The underlying objective is to improve the efficiency of their inventory policy by exploiting pharmacy historical data. To this end, the pharmacy staff was aided by a decision support system that provided them with quantities needed for the satisfaction of clinical needs and the risk of stockout in case no order is placed for different time horizons. With this information in mind, the pharmacy service takes the final order decisions. The results obtained during a test period of four months are provided and compared with those of a previous model predictive control approach, which was implemented in the same hospital in the past, and with the usual policy of the pharmacy department.

RESUMEN

The automatic identification and segmentation of edemas associated with diabetic macular edema (DME) constitutes a crucial ophthalmological issue as they provide useful information for the evaluation of the disease severity. According to clinical knowledge, the DME disorder can be categorized into three main pathological types: serous retinal detachment (SRD), cystoid macular edema (CME), and diffuse retinal thickening (DRT). The implementation of computational systems for their automatic extraction and characterization may help the clinicians in their daily clinical practice, adjusting the diagnosis and therapies and consequently the life quality of the patients. In this context, this paper proposes a fully automatic system for the identification, segmentation and characterization of the three ME types using optical coherence tomography (OCT) images. In the case of SRD and CME edemas, different approaches were implemented adapting graph cuts and active contours for their identification and precise delimitation. In the case of the DRT edemas, given their fuzzy regional appearance that requires a complex extraction process, an exhaustive analysis using a learning strategy was designed, exploiting intensity, texture, and clinical-based information. The different steps of this methodology were validated with a heterogeneous set of 262 OCT images, using the manual labeling provided by an expert clinician. In general terms, the system provided satisfactory results, reaching Dice coefficient scores of 0.8768, 0.7475, and 0.8913 for the segmentation of SRD, CME, and DRT edemas, respectively.

RESUMEN

This study explores the perceptions of newly graduated nurses regarding the baccalaureate thesis (BT) writing process. A qualitative approach with content analysis was adopted. Thirteen newly graduated nurses participated in the study. The inclusion criterion was having completed the BT during their university education as nurses within 3 years of the study. Information was obtained through semistructured interviews. Data collection began in June 2018 and ended in March 2019, once saturation of information was reached. Three major categories were identified: the beginning of the process, the advantages of Baccalaureate thesis writing, and the teacher's role. The participants expressed that their training focused on a synthetic and particular type of writing that is necessary for clinical scenarios but not suitable for scientific academic texts. Additionally, reflective diaries were described as a powerful writing practice during their studies. Participants conceive the realization of the baccalaureate thesis as a difficult process, especially as regards selecting, synthesizing, and writing about the available information, processes that they indicated generate anxiety. Academic writing skills should be specifically included in the nursing curriculum.

RESUMEN

BACKGROUND: America's increasing HIV epidemic among youth suggests the need to identify novel strategies to leverage services and settings where youth at high risk (YAHR) for HIV can be engaged in prevention. Scalable, efficacious, and cost-effective strategies are needed, which support youth during developmental transitions when risks arise. Evidence-based behavioral interventions (EBIs) have typically relied on time-limited, scripted, and manualized protocols that were often delivered with low fidelity and lacked evidence for effectiveness. OBJECTIVE: This study aims to examine efficacy, implementation, and cost-effectiveness of easily mountable and adaptable, technology-based behavioral interventions in the context of an enhanced standard of care and study assessments that implement the guidelines of Centers for Disease Control and Prevention (CDC) for routine, repeat HIV, and sexually transmitted infection (STI) testing for high-risk youth. METHODS: Youth aged between 12 and 24 years (n=1500) are being recruited from community-based organizations and clinics serving gay, bisexual, and transgender youth, homeless youth, and postincarcerated youth, with eligibility algorithms weighting African American and Latino youth to reflect disparities in HIV incidence. At baseline and 4-month intervals over 24 months (12 months for lower-risk youth), interviewers monitor uptake of HIV prevention continuum steps (linkage to health care, use of pre- or postexposure prophylaxis, condoms, and prevention services) and secondary outcomes of substance use, mental health, and housing security. Assessments include rapid diagnostic tests for HIV, STIs, drugs, and alcohol. The study is powered to detect modest intervention effects among gay or bisexual male and transgender youth with 70% retention. Youth are randomized to 4 conditions: (1) enhanced standard of care of automated text-messaging and monitoring (AMM) and repeat HIV/STI testing assessment procedures (n=690); (2) online group peer support via private social media plus AMM (n=270); (3) coaching that is strengths-based, youth-centered, unscripted, based on common practice elements of EBI, available over 24 months, and delivered by near-peer paraprofessionals via text, phone, and in-person, plus AMM (n=270); and (4) online group peer support plus coaching and AMM (n=270). RESULTS: The project was funded in September 2016 and enrollment began in May 2017. Enrollment will be completed between June and August 2019. Data analysis is currently underway, and the first results are expected to be submitted for publication in 2019. CONCLUSIONS: This hybrid implementation-effectiveness study examines alternative models for implementing the CDC guidelines for routine HIV/STI testing for YAHR of acquiring HIV and for delivering evidence-based behavioral intervention content in modular elements instead of scripted manuals and available over 24 months of follow-up, while also monitoring implementation, costs, and effectiveness. The greatest impacts are expected for coaching, whereas online group peer support is expected to have lower impact but may be more cost-effective.

RESUMEN

BACKGROUND: Over 20% of HIV diagnoses in the United States are among youth aged 12-24 years. Furthermore, youth have the lowest rates of uptake and adherence to antiretroviral (ARV) medications and are least aware of their HIV status. OBJECTIVE: Our objective was to design a set of interrelated studies to promote completion of each step of the HIV Prevention Continuum by uninfected youth at high risk (YHR), as well as completion of steps in the Treatment Continuum by youth living with HIV (YLH). METHODS: Gay, bisexual, and transgender youth; homeless youth; substance-abusing youth; youth with criminal justice contact; and youth with significant mental health challenges, particularly black and Latino individuals, are being recruited from 13 community-based organizations, clinics, drop-in centers, and shelters in Los Angeles and New Orleans. Youth are screened on the basis of self-reports and rapid diagnostic tests for HIV, drug use, and sexually transmitted infections and, then, triaged into one of 3 studies: (1) an observational cohort of YLH who have never received ARV medications and are then treated-half initially are in the acute infection period (n=36) and half with established HIV infection (n=36); (2) a randomized controlled trial (RCT) for YLH (N=220); and (3) an RCT for YHR (N=1340). Each study contrasts efficacy and costs of 3 interventions: an automated messaging and weekly monitoring program delivered via text messages (short message service, SMS); a peer support intervention delivered via social media forums; and coaching, delivered via text message (SMS), phone, and in-person or telehealth contacts. The primary outcomes are assessing youths' uptake and retention of and adherence to the HIV Prevention or Treatment Continua. Repeat assessments are conducted every 4 months over 24 months to engage and retain youth and to monitor their status. RESULTS: The project is funded from September 2016 through May 2021. Recruitment began in May 2017 and is expected to be completed by June 2019. We expect to submit the first results for publication by fall 2019. CONCLUSIONS: Using similar, flexible, and adaptable intervention approaches for YLH and YHR, this set of studies may provide a roadmap for communities to broadly address HIV risk among youth. We will evaluate whether the interventions are cost-efficient strategies that can be leveraged to help youth adhere to the actions in the HIV Prevention and Treatment Continua.

RESUMEN

BACKGROUND AND OBJECTIVE: The detection and characterization of the intraretinal fluid accumulation constitutes a crucial ophthalmological issue as it provides useful information for the identification and diagnosis of the different types of Macular Edema (ME). These types are clinically defined, according to the clinical guidelines, as: Serous Retinal Detachment (SRD), Diffuse Retinal Thickening (DRT) and Cystoid Macular Edema (CME). Their accurate identification and characterization facilitate the diagnostic process, determining the disease severity and, therefore, allowing the clinicians to achieve more precise analysis and suitable treatments. METHODS: This paper proposes a new fully automatic system for the identification and characterization of the three types of ME using Optical Coherence Tomography (OCT) images. In the case of SRD and CME edemas, multilevel image thresholding approaches were designed and combined with the application of ad-hoc clinical restrictions. The case of DRT edemas, given their complexity and fuzzy regional appearance, was approached by a learning strategy that exploits intensity, texture and clinical-based information to identify their presence. RESULTS: The system provided satisfactory results with F-Measures of 87.54% and 91.99% for the DRT and CME detections, respectively. In the case of SRD edemas, the system correctly detected all the cases that were included in the designed dataset. CONCLUSIONS: The proposed methodology offered an accurate performance for the individual identification and characterization of the three different types of ME in OCT images. In fact, the method is capable to handle the ME analysis even in cases of significant severity with the simultaneous existence of the three ME types that appear merged inside the retinal layers.

RESUMEN

The Juvenile Arthritis Multidimensional Assessment Report (JAMAR) is a new parent/patient reported outcome measure that enables a thorough assessment of the disease status in children with juvenile idiopathic arthritis (JIA). We report the results of the cross-cultural adaptation and validation of the parent and patient versions of the JAMAR in the Castilian Spanish language. The reading comprehension of the questionnaire was tested in 10 JIA parents and patients. Each participating centre was asked to collect demographic, clinical data and the JAMAR in 100 consecutive JIA patients or all consecutive patients seen in a 6-month period and to administer the JAMAR to 100 healthy children and their parents. The statistical validation phase explored descriptive statistics and the psychometric issues of the JAMAR: the three Likert assumptions, floor/ceiling effects, internal consistency, Cronbach's alpha, interscale correlations, test-retest reliability and construct validity (convergent and discriminant validity). A total of 526 JIA patients (8.6% systemic, 49.4% oligoarticular, 18.2% RF negative polyarthritis, 23.8% other categories) and 78 healthy children, were enrolled in six centres. The JAMAR components discriminated well healthy subjects from JIA patients. All JAMAR components revealed good psychometric performances. In conclusion, the Castilian Spanish version of the JAMAR is a valid tool for the assessment of children with JIA and is suitable for use both in routine clinical practise and clinical research.

RESUMEN

Black men who have sex with men and women (BMSMW) are at increased HIV risk, but few efficacious interventions meet their unique needs. Three HIV prevention interventions were evaluated with a common protocol. Baseline data were pooled to describe sexual behavior involving transmission risk with male, female, and male-to-female transgender partners and identify factors associated with transmission risk. BMSMW from Los Angeles, Philadelphia, and Chicago who reported sexual risk and bisexual behavior in the past year were recruited via modified chain referral sampling and community recruitment. Baseline assessments were conducted via audio computer-assisted interview and sexual behaviors assessed over the past 3 months. From December 2010 to November 2012, 584 BMSMW were enrolled across the three cities. More than half (55%) were recruited by other participants. Overall, the mean age was 43 years. Seventy-five percent reported an annual income <$10,000 and selling sex was prevalent (31%). Three-quarters identified as bisexual. Thirty-nine percent were HIV-positive. Among HIV-positive participants, 46% reported sex without condoms with HIV-negative or unknown male partners and 45% with HIV-negative or unknown female partners. Overall, factors associated with sex without condoms included network size, education, income, sexual orientation identification, HIV status, exchange sex, homonegativity, and social support. Findings support the need for enhanced HIV prevention efforts for this population. Future studies should examine contextual factors in addition to individual risk behaviors to inform the development and implementation of promising strategies to prevent HIV and promote the overall health and wellness of BMSMW and their sexual partners.

RESUMEN

Objetivo: Analizar la satisfacción sexual percibida, las disfunciones sexuales, la satisfacción con las relaciones afectivas, la confianza y la comunicación con la pareja actual, en función del antecedente de abuso sexual en la infancia y la adolescencia, y el tipo padecido, en mujeres atendidas dentro del Programa de Atención a la Salud Sexual y Reproductiva de Catalunya (PASSIR). Método: Estudio multicéntrico, descriptivo y transversal. Participaron 1013 mujeres mayores de 18 años, atendidas en visita psicológica en los 24 Centros del PASSIR. Se utilizó un cuestionario estructurado autoadministrado y anónimo adaptado del Cuestionario de abuso sexual en la infancia y adolescencia de Wyatt (1985) y Dubé et al. (2005), y el Female Sexual Function Index de Rosen (2000). Análisis estadístico descriptivo, bivariado y multivariado. Resultados: Todas las disfunciones sexuales resultaron significativamente más frecuentes en las mujeres que padecieron abuso sexual en la infancia y la adolescencia, y la satisfacción sexual percibida fue menor. Las situaciones de abuso sexual con intento de penetración o penetración se asociaron a más dificultades de excitación y mayor rechazo. Las mujeres que sufrieron abuso sexual en la infancia y la adolescencia manifestaron menos confianza y más dificultades de comunicación con la pareja. Conclusiones: Es necesario identificar un posible abuso sexual en la infancia y la adolescencia en las mujeres que consultan por problemas con sus parejas, y continuar investigando sobre factores protectores e intervenciones terapéuticas tendentes a paliar las consecuencias de dicho abuso al llegar a la vida adulta (AU)


Objective: To analyse perceived sexual satisfaction, sexual dysfunction, satisfaction with affective relationships and confidence and communication in existing relationships, related to a past history of childhood sexual abuse (CSA) and type suffered, among women treated as part of the Catalonian Sexual and Reproductive Health Care Programme (PASSIR). Method: Multicentric, descriptive, cross-sectional study. A total of 1,013 women over the age of 18 years, who underwent psychological therapy at any of the 24 PASSIR centres, were enrolled. A structured, anonymised, self-administered Sex History Questionnaire adapted from Wyatt (1985) & Dubé et al. (2005), and the Female Sexual Function Index (Rosen, 2000), were used. Statistical analysis was descriptive, bivariate and multivariate. Results: Women who suffered childhood sexual abuse had a significantly higher prevalence of sexual dysfunction, with lower perceived sexual satisfaction. CSA with penetration or attempted penetration was associated with greater arousal difficulties and greater rejection. Women who experienced CSA were less confident and experienced greater communication difficulties with their partner. Conclusions: It is necessary to identify potential childhood sexual abuse among women who seek therapy due to relationship problems. It is also necessary to continue research into protective factors and therapeutic interventions to alleviate the consequences of CSA in adult life (AU)
