Descelularización y regeneración de tráquea porcina: un acercamiento a la ingeniería tisular / Decellularization and Regeneration of Porcine Trachea: an Approach to Tissue Engineering

Resumen Antecedentes: la ingeniería tisular permite obtener órganos como injertos a partir de tejidos descelularizados, regenerados con células autólogas. Objetivo: descelularizar y regenerar tráqueas porcinas. Material y métodos: se descelularizaron tráqueas porcinas colocándolas cada una en el epiplón de cuatro cerdos Yorkshire para su regeneración in vivo. Una tráquea desce-lularizada con tritón (DT), descelularizada con desoxicolato (DD), descelularizada con desoxicolato y reforzada con un polímero y células epiteliales (DDR), y una nativa crio-preservada (NC). Después de 8 días se obtuvieron la DD, NC y DDR; y al día 15, la DT. Se las evaluó mecánica e histológicamente, se realizó el análisis casuístico. Resultados: las tráqueas descelularizadas conservaron la integridad del cartílago, sin diferencias mecánicas, excepto la DDR con mayor rigidez. Las tráqueas regeneradas presentaron menor rigidez, excepto la DDR que además perdió el epitelio y la vascula-ridad. Las DT, DD mostraron epitelio no respiratorio, fibrosis y vasculogénesis con in-flamación. Conclusiones: las matrices conservaron sus características mecánicas. La regenera-ción in vivo ofrece ventajas como la esterilidad, interacción celular, nutrientes; es senci-llo, factible y económico, pero no hay control del crecimiento celular y vascularización, y los tejidos presentaron alteraciones mecánicas e histológicas. El polímero impidió la re-epitelialización y revascularización. Este estudio abre la posibilidad de mejorar las me-todologías de ingeniería tisular aplicadas al tejido traqueal.

Rico-EscobarDescelularización y regeneración de tráqueaISSN 2953-3414Materials and Methods: Porcine tracheas were decellularized by placing each one in the omentum of four Yorkshire pigs for regeneration in vivo. A trachea decellularized with triton (DT), decellularized with deoxycholate (DD), decellularized with deoxycho-late and reinforced with a polymer, and epithelial cells (DDR), and a cryopreserved na-tive (NC). After 8 days, the DD, NC and DDR were obtained; and on day 15, the DT. The evaluation was mechanically and histologically, performing the case analysis.Results: the decellularized tracheas preserved the integrity of the cartilage, with no me-chanical differences, except for the DDR with greater rigidity. The regenerated trache-as presented less rigidity, except the DDR, which also lost the epithelium and vascular-ity. The DT, DD showed non-respiratory epithelium, fibrosis and vasculogenesis with inflammation.Conclusions: the matrices retained their mechanical characteristics, in vivo regenera-tion offers advantages such as sterility, cell interaction, nutrients; it is simple, feasible and economical, but there is no control of cell growth and vascularization, and the tis-sues presented mechanical and histological alterations. The polymer prevented re-epi-thelialization and revascularization. This study opens the possibility of improving tissue engineering methodologies applied to tracheal tissue.

Building bridges through cultural adaptation: Examining the initial impact of a culturally adapted parent training intervention for the Chilean context.

Child exposure to maltreatment and neglect constitutes a significant public health problem throughout Latin American and Caribbean (LAC) countries. Although evidence-based parent training (PT) interventions constitute an empirically demonstrated alternative to prevent child maltreatment and neglect, multiple implementation barriers have prevented the large-scale dissemination of evidence-based PT interventions across LAC countries. This selective prevention study consisted of an exploratory quasi-experimental design implemented in Chile, aimed at examining the initial impact of a culturally adapted version of the evidence-based PT intervention known as GenerationPMTO©. The parenting intervention was adapted in a previous pilot study, according to a rigorous model of cultural adaptation. Based on self-reports completed by 281 caregivers, when compared to baseline measurements, significant improvements at intervention completion were observed in the majority of caregivers' parenting practices, as well as child internalizing and externalizing problematic behaviors. This study provides promising initial empirical evidence that efficacious PT interventions developed in the US can be transported to Latin American contexts, as long as they are thoroughly adapted to achieve high contextual and cultural relevance. The rates of child maltreatment across LAC countries constitute an urgent and permanent call for strongly promoting this line of prevention research.

The impact of a parent-based prevention intervention on Mexican-descent youths' perceptions of harm associated with drug use: Differential intervention effects for male and female youths.

Parent training (PT) interventions reduce the likelihood of youth problematic behaviors, including drug use. However, the dissemination of culturally adapted PT interventions in low-income Latina/o immigrant communities remains scarce. In this selective prevention study, we examined the extent to which exposure to CAPAS-Youth, a culturally adapted version of the PT intervention known as GenerationPMTO© , resulted in increased adolescent perception of harm associated with use of alcohol and other drugs. In a randomized controlled trial with 71 Latina/o immigrant families (95% of parents self-identified as Mexican origin, n = 98), 37 families were allocated to the CAPAS-Youth intervention condition versus wait-list control (n = 34 families). According to adolescents' reports at intervention completion, significant increased levels of perceived harm associated with drug use were found for female youths, but not for males. Differential results indicate the importance of tailoring PT prevention interventions according to youths' sex differences (i.e., males vs. females).

A culturally adapted parenting intervention for the Chilean context: Qualitative indicators of participant satisfaction and contextual and cultural relevance.

Parent training (PT) interventions constitute an empirically demonstrated alternative to promote effective parenting practices and prevent child behavioral and mental health problems. However, the dissemination of evidence-based PT interventions across Latin America remains scarce. This qualitative study had the primary objective of evaluating the level of acceptability of a culturally adapted version of the PT intervention known as GenerationPMTO© , adapted for the Chilean context. According to qualitative reports provided by 24 Chilean caregivers exposed to the culturally adapted parenting intervention, the intervention was perceived by caregivers as useful for their parenting practices, as well as contextually and culturally relevant. Current qualitative findings indicate that the culturally adapted PT intervention holds promise for larger dissemination in the Chilean context.

Outcomes of octogenarians and nonagenarians with Pseudomonas aeruginosa bacteremia: a multicenter retrospective study.

BACKGROUND: P. aeruginosa bacteremia is a common and severe infection carrying high mortality in older adults. We aimed to evaluate outcomes of P. aeruginosa bacteremia among old adults (≥ 80 years). METHODS: We included the 464/2394 (19%) older adults from a retrospective multinational (9 countries, 25 centers) cohort study of individuals hospitalized with P. aeruginosa bacteremia. Bivariate and multivariable logistic regression models were used to evaluate risk factors for 30-day mortality among older adults. RESULTS: Among 464 adults aged ≥ 80 years, the mean age was 84.61 (SD 3.98) years, and 274 (59%) were men. Compared to younger patients, ≥ 80 years adults had lower Charlson score; were less likely to have nosocomial acquisition; and more likely to have urinary source. Thirty-day mortality was 30%, versus 27% among patients 65-79 years (n = 894) and 25% among patients < 65 years (n = 1036). Multivariate analysis for predictors of mortality among patients ≥ 80 years, demonstrated higher SOFA score (odds ratio [OR] 1.36, 95% confidence interval [CI] 1.23-1.51, p < 0.001), corticosteroid therapy (OR 3.15, 95% CI: 1.24-8.01, p = 0.016) and hospital acquired P. aeruginosa bacteremia (OR 2.30, 95% CI: 1.33-3.98, p = 0.003) as predictors. Appropriate empirical therapy within 24 h, type of definitive anti-pseudomonal drug, and type of regimen (monotherapy or combination) were not associated with 30-day mortality. CONCLUSIONS: In older adults with P. aeruginosa bacteremia, background conditions, place of acquisition, and disease severity are associated with mortality, rather than the antimicrobial regimen. In this regard, preventive efforts and early diagnosis before organ failure develops might be beneficial for improving outcomes.

Culturally adapting an evidence-based parenting intervention for the Chilean context: Balancing fidelity, context, and cultural relevance.

The dissemination of evidence-based parent training (PT) interventions remains extremely limited in Latin American countries. This is concerning when considering the high prevalence of child maltreatment associated with punitive parenting practices across countries in the region. Furthermore, efforts to disseminate PT interventions must be conducted by adhering to the core parenting components that have established effectiveness for such interventions, while ensuring contextual and cultural relevance for focus populations. In this manuscript, we describe the cultural adaptation of an evidence-based PT intervention in the context of Chile. This initial phase of adaptation was informed by the theoretical tenets of the Ecological Validity Model of cultural adaptation (Bernal et al., J. Abnorm. Child Psychol., 23, 1995, 67). According to findings from a qualitative thematic analysis conducted with five interventionists in training, therapists perceived that the intervention's core components were relevant to Chilean caregivers who participated in the parenting program. Interventionists also provided specific suggestions to enhance the intervention's contextual and cultural relevance. This investigation illustrates the importance of culturally adapting evidence-based interventions according to comprehensive cultural adaptation frameworks, prior to engaging in large-scale dissemination of adapted interventions in Latin American contexts.

Baseline Target Moderation and Baseline Target Moderation Mediation Approaches: Reflections on Cultural Adaptation and Social Justice.

Baseline target moderation (BTM) and baseline target moderated mediation (BTMM) constitute critical methodological and analytical approaches for the future of prevention science. However, the continuing refinement and utilization of these approaches carry important challenges when considering equity challenges that remain present in the prevention science field. Accordingly, this commentary is focused on examining cultural and contextual considerations associated with the set of articles included in this study, as well as directions for enhancing future research by embracing a solid grounding on equity perspectives. For example, to which extent do BTM and BTMM approaches include variables of relevance such as perceived discrimination, economic adversity, and other cultural and contextual domains that impact the lives of underserved diverse populations? In addition to providing a review of the articles included in this issue, recommendations are included for informing future prevention research according to equity perspectives.

All Things Considered: Examining Mentoring Relationships Between White Mentors and Black Youth in Community-Based Youth Mentoring Programs.

Background: Community-based youth mentoring programs are popular interventions that serve a large number of Black youths throughout the country. Interestingly, the majority of mentors who volunteer their time for mentoring organizations identify as non-Hispanic White. This study examines how White mentors address topics acknowledging ethnic/racial identity and issues centered around social justice and recognize their own privileges when mentoring Black youth in community-based youth mentoring programs. Objective: The aims of the current study were to examine: (a) whether and how White volunteer mentors address ethnic/racial identity, racial socialization, and oppression in the mentoring relationship and (b) how White mentors' awareness of their own positionality and privilege impacted how they addressed ethnic/racial identity, racial socialization, and oppression in the mentoring relationship with Black youth. Method: Utilizing a constructivist grounded theory approach, in-depth semi-structured interviews were conducted with 26 current and former mentors from six different Big Brothers Big Sisters community-based mentoring programs across the United States. Results: Findings reveal that some mentors felt uncomfortable discussing issues centered around race and others do not think it is relevant at all. Further, findings demonstrated that mentoring Black youth significantly impacts mentors' perceived awareness of social issues and acknowledgment of privileges they hold. Conclusions: Current findings highlight the need for youth mentoring programs to provide training and resources to help White mentors discuss implications of race and broader social justice issues with the Black youth they mentor.

Ethical by Design: Engaging the Community to Co-design a Digital Health Ecosystem to Improve Overdose Prevention Efforts Among Highly Vulnerable People Who Use Drugs.

Introduction: The COVID-19 pandemic highlighted significant structural barriers that exacerbated health inequities among people at-risk for overdose. Digital health technologies have the potential to overcome some of these barriers; however, development of these technologies often fails to include people who use drugs and community key stakeholders in the development and dissemination process. Consequently, this may exacerbate health inequities and the digital divide among underserved, highly vulnerable people who use drugs. Methods: The current study employed community-engaged research methods to develop and implement a digital platform to improve overdose surveillance among harm reductionists in Texas. We used a co-design process with four community advisory boards (CABs) and conducted qualitative interviews among N = 74 key stakeholders (n = 24 people who use drugs; n = 20 first responders, n = 20 harm reductionists, n = 10 overdose prevention and response experts) to inform initial design and development. Results: Several key themes emerged through the qualitative data pertaining to technical features and human factors applications. In regards to technical features, participants highlighted the importance of developing a unified system of overdose reporting and data sharing among community organizations within a county or region to better inform overdose surveillance and community outreach efforts. This system should include flexible data entry methods, have offline usage capability, be user friendly, and allow for tracking of overdose-related supply distribution. Key human factor themes included the need to use person-centered language, to preserve the established trust of the community organizations among people who use drugs, to be tailored to specific target user groups (e.g., harm reduction workers, people who use drugs, first responders), and maintain transparency of data usage. Further, participants noted the importance of developing a platform that will facilitate client conversations about overdose when doing outreach in the field. These themes were reviewed by our CABs, academic, and industry partners to design an overdose digital platform uniquely tailored to community-based organizations providing harm reduction and overdose response efforts. Discussion: Community engagement throughout the development process is critical toward developing digital health tools for underserved people who use drugs. Dismantling the power structure among academic and industry partners is critical toward creating equity in engagement of community-based partners, particularly among persons with lived experience in addiction, a history of incarceration, or financial challenges. Our study highlights a multisectoral co-design process across community-academic-industry partners to develop a digital health tool tailored to the unique needs of community-based harm reduction organizations serving highly vulnerable people who use drugs. These partnerships are essential toward creating impact and reducing health disparities among highly vulnerable people who use drugs.

Duration of Treatment for Pseudomonas aeruginosa Bacteremia: a Retrospective Study.

INTRODUCTION: There is no consensus regarding optimal duration of antibiotic therapy for Pseudomonas aeruginosa bacteremia. We aimed to evaluate the impact of short antibiotic course. METHODS: We present a retrospective multicenter study including patients with P. aeruginosa bacteremia during 2009-2015. We evaluated outcomes of patients treated with short (6-10 days) versus long (11-15 days) antibiotic courses. The primary outcome was a composite of 30-day mortality or bacteremia recurrence and/or persistence. Univariate and inverse probability treatment-weighted (IPTW) adjusted multivariate analysis for the primary outcome was performed. To avoid immortal time bias, the landmark method was used. RESULTS: We included 657 patients; 273 received a short antibiotic course and 384 a long course. There was no significant difference in baseline characteristics of patients. The composite primary outcome occurred in 61/384 patients in the long-treatment group (16%) versus 32/273 in the short-treatment group (12%) (p = 0.131). Mortality accounted for 41/384 (11%) versus 25/273 (9%) of cases, respectively. Length of hospital stay was significantly shorter in the short group [median 13 days, interquartile range (IQR) 9-21 days, versus median 15 days, IQR 11-26 days, p = 0.002]. Ten patients in the long group discontinued antibiotic therapy owing to adverse events, compared with none in the short group. On univariate and multivariate analyses, duration of therapy was not associated with the primary outcome. CONCLUSIONS: In this retrospective study, 6-10 days of antibiotic course for P. aeruginosa bacteremia were as effective as longer courses in terms of survival and recurrence. Shorter therapy was associated with reduced length of stay and less drug discontinuation.

A Culturally Adapted Parenting Intervention for Mexican-Origin Immigrant Families with Adolescents: Integrating Science, Culture, and a Focus on Immigration-Related Adversity.

Low-income Latina/o immigrants are very likely to experience intense contextual challenges in the USA, such as limited exposure to culturally relevant parent training (PT) prevention interventions. This prevention study consisted of an exploratory randomized controlled trial, aimed at empirically testing the implementation feasibility and initial efficacy of a culturally adapted version of the evidence-based PT intervention known as GenerationPMTO©. The parenting intervention was adapted to overtly address immigration-related stressors, discrimination, and challenges associated with biculturalism. Seventy-one Mexican-origin immigrant mothers participated in this study and were allocated to one of two conditions: (a) culturally adapted GenerationPMTO (i.e., CAPAS-Youth) or (b) wait-list control. Measurements were completed at baseline (T1) and intervention completion (T2). When compared to mothers in the control condition at T2, CAPAS-Youth participants reported significant improvements on four of the core parenting practices delivered in the CAPAS-Youth intervention. As hypothesized, no significant differences in limit-setting skills were identified at T2. With regards to adolescents' outcomes, mothers exposed to CAPAS-Youth reported significant improvements in youth internalizing and externalizing behaviors at T2 when compared to a wait-list control condition. Mothers in both conditions also reported significant reductions in levels of immigration-related stress. Current findings indicate the feasibility of implementing CAPAS-Youth within a context of considerable adversity, as well as the beneficial impacts of the parent-based intervention on salient parenting and youth outcomes.

Creating a Digital Trauma Informed Space: Chat and Text Advocacy for Survivors of Violence.

There is little research on virtual service models like chat and text services in agencies that work with survivors of intimate partner violence (IPV) and sexual assault (SA). This study fills a gap in the research by exploring how chat and text services are provided in one IPV and SA-focused community organization. We analyzed chat and text transcripts (n = 392) from a large multiservice, multivictimization focused agency, and conducted interviews with 11 advocates providing chat and text services through the agency hotline. Staff interviews were analyzed using grounded theory and transcripts were analyzed using content analysis. Results indicate chat/text services provide a space for connection, resource provision, education, and access to resource gain in a timely, concise, and survivor-centered way. The five major goals for chat/text advocacy models include the following: (1) rapid access to support and connection; (2) identification of options and needs for each service user; (3) increased access to resources and supports; (4) expanded understanding of violence, abuse, and harm; and (5) improvement of survivor safety. The research team identified 15 general advocacy skills and 4 chat and text specific skills used by chat/text advocates to reach program goals. Findings highlight the utility of chat/text services for increasing access to support services for survivors of violence, particularly adolescents, emerging adults, those living with an abusive individual, and during times of emergency. Future research should continue to explore the promising practice modality of chat/text services for providing advocacy to underserved and hard-to-reach populations.

Reducing mental health disparities among racially and ethnically diverse populations: A review of couple and family intervention research methods (2010-2019).

Racially and ethnically diverse and globally underserved populations continue to experience mental health disparities. The goal of this review was to examine the extent to which diverse populations were included in couple and family intervention research over the past decade and whether these studies were conducted with attention to issues of diversity. We performed a review of 271 articles reviewed in the current special issue on the efficacy and effectiveness of couple and family interventions across 11 mental health topics. Overall, only 68 of the 271 (25%) articles included predominately racial/ethnic minority samples or globally underserved populations. Among articles (n = 60) describing US-based research with racial/ethnic minority samples, there was a pattern of inattention to methodological considerations relevant to diverse populations. Although some progress was noted, more research is necessary. Specifically, we call for research that advances social justice by using critically conscious methods to promote mental health equity.

Combination versus monotherapy as definitive treatment for Pseudomonas aeruginosa bacteraemia: a multicentre retrospective observational cohort study.

BACKGROUND: Pseudomonas aeruginosa bacteraemia is a common and serious infection. No consensus exists regarding whether definitive combination therapy is superior to monotherapy. We aimed to evaluate the impact of combination therapy on mortality. METHODS: This was a multicentre retrospective study (nine countries, 25 centres), including 1277 patients with P. aeruginosa bacteraemia during 2009-15. We evaluated the association between ß-lactam plus aminoglycoside or quinolone combination therapy versus ß-lactam monotherapy and mortality. The primary outcome was 30 day all-cause mortality. Univariate and multivariate Cox regression analyses were conducted, introducing combination as a time-dependent variable. Propensity score was conducted to adjust for confounding for choosing combination therapy over monotherapy. RESULTS: Of 1119 patients included, 843 received definitive monotherapy and 276 received combination therapy (59% aminoglycoside and 41% quinolone). Mortality at 30 days was 16.9% (189/1119) and was similar between combination (45/276; 16.3%) and monotherapy (144/843; 17.1%) groups (P = 0.765). In multivariate Cox regression, combination therapy was not associated with reduced mortality (HR 0.98, 95% CI 0.64-1.53). No advantage in terms of clinical failure, microbiological failure or recurrent/persistent bacteraemia was demonstrated using combination therapy. Likewise, adverse events and resistance development were similar for the two regimens. CONCLUSIONS: In this retrospective cohort, no mortality advantage was demonstrated using combination therapy over monotherapy for P. aeruginosa bacteraemia. Combination therapy did not improve clinical or microbiological failure rates, nor affect adverse events or resistance development. Our finding of no benefit with combination therapy needs confirmation in well-designed randomized controlled trials.

Strengthening a Culture of Prevention in Low- and Middle-Income Countries: Balancing Scientific Expectations and Contextual Realities.

Relevant initiatives are being implemented in low- and middle-income countries (LMICs) aimed at strengthening a culture of prevention. However, cumulative contextual factors constitute significant barriers for implementing rigorous prevention science in these contexts, as defined by guidelines from high-income countries (HICs). Specifically, disseminating a culture of prevention in LMICs can be impacted by political instability, limited health coverage, insecurity, limited rule of law, and scarcity of specialized professionals. This manuscript offers a contribution focused on strengthening a culture of prevention in LMICs. Specifically, four case studies are presented illustrating the gradual development of contrasting prevention initiatives in northern and central Mexico, Panamá, and Sub-Saharan Africa. The initiatives share the common goal of strengthening a culture of prevention in LMICs through the dissemination of efficacious parenting programs, aimed at reducing child maltreatment and improving parental and child mental health. Together, these initiatives illustrate the following: (a) the relevance of adopting a definition of culture of prevention characterized by national commitments with expected shared contributions by governments and civil society, (b) the need to carefully consider the impact of context when promoting prevention initiatives in LMICs, (c) the iterative, non-linear, and multi-faceted nature of promoting a culture of prevention in LMICs, and (d) the importance of committing to cultural competence and shared leadership with local communities for the advancement of prevention science in LMICs. Implications for expanding a culture of prevention in LMICs are discussed.

Parenting in the Midst of Adversity: Tailoring a Culturally Adapted Parent Training Intervention According to the Parenting Experiences of Mexican-Origin Caregivers.

Although parent training (PT) interventions are considered the gold standard for preventing externalizing behaviors in children and youth, their dissemination in low-income Latina/o immigrant communities continues to be scarce throughout the United States (US). An alternative to address this gap in service delivery consists of implementing culturally adapted PT interventions characterized by cultural and contextual relevance. Thus, the main objective of this qualitative study was to document salient immigration-related experiences, as well as parenting needs and challenges, as reported by 30 low-income Mexican-origin immigrant caregivers residing in an urban setting in the Southern United States. The research methodology was guided by the tenets of the Thematic Analysis approach, which involved collecting data through a series of focus group interviews. Qualitative research findings highlight the importance of culturally and contextually tailoring adapted PT prevention interventions, prior to their delivery in contexts that differ from those in which interventions were originally adapted. Specifically, parents in the current investigation provided detailed accounts of immigration-related stressors that are highly relevant to inform recruitment procedures, intervention curriculum, and intervention delivery activities.

Aunque las intervenciones de capacitaciones para padres se consideran la norma de oro para prevenir los comportamientos de externalización en los niños y los jóvenes, su difusión en las comunidades de inmigrantes latinos de bajos recursos continúa siendo escasa en todo Estados Unidos. Una alternativa para minimizar esta brecha en la prestación del servicio consiste en implementar intervenciones de capacitación para padres adaptadas culturalmente que se caractericen por la relevancia cultural y contextual. Por lo tanto, el objetivo principal de este estudio cualitativo fue documentar las experiencias destacadas relacionadas con la inmigración, así como las necesidades y las dificultades de la crianza, según lo informado por 30 cuidadores inmigrantes de origen mexicano y de bajos recursos que viven en un entorno urbano en el sur de EE. UU. La metodología de investigación estuvo guiada por los principios del método del análisis temático, que consistió en recopilar datos mediante una serie de entrevistas a grupos de análisis. Los resultados de la investigación cualitativa destacan la importancia de amoldar culturalmente y contextualmente las intervenciones preventivas y adaptadas de capacitación para padres antes de su implementación en contextos distintos a aquellos a los que fueron adaptadas originalmente. Específicamente, los padres de la investigación actual explicaron detalladamente los factores de estrés relacionados con la inmigración que son sumamente relevantes para preparar los procedimientos de captación, el currículo de intervención y las actividades de implementación de la intervención.

COVID-19 Interconnectedness: Health Inequity, the Climate Crisis, and Collective Trauma.

The COVID-19 pandemic brings to the forefront the complex interconnected dilemmas of globalization, health equity, economic security, environmental justice, and collective trauma, severely impacting the marginalized and people of color in the United States. This lack of access to and the quality of healthcare, affordable housing, and lack of financial resources also continue to have a more significant impact on documented and undocumented immigrants. This paper aims at examining these critical issues and developing a framework for family therapists to address these challenges by focusing on four interrelated dimensions: cultural values, social determinants of health, collective trauma, and the ethical and moral responsibility of family therapists. Given the fact that family therapists may unwittingly function as the best ally of an economic and political system that perpetuates institutionalized racism and class discrimination, we need to utilize a set of principles, values, and practices that are not just palliative or after the fact but bring forth into the psychotherapeutic and policy work a politics of care. Therefore, a strong call to promote and advocate for the broader continuum of health and critical thinking preparing professionals to meet the challenges of health equity, as well as economic and environmental justice, is needed. The issues discussed in this paper are specific to the United States despite their relevance to family therapy as a field. We are mindful not to generalize the United States' reality to the rest of the world, recognizing that issues discussed in this paper could potentially contribute to international discourse.

La pandemia de la COVID-19 ha puesto en primer plano los dilemas complejos e interconectados de la globalización, la equidad sanitaria, la seguridad económica, la justicia ambiental y el trauma colectivo, afectando gravemente a las personas marginadas y de color de los Estados Unidos. Esta falta de acceso a asistencia sanitaria de calidad, a viviendas asequibles, y la falta de recursos económicos también continúan teniendo un efecto más significativo en los inmigrantes documentados e indocumentados. Este artículo tiene como finalidad analizar estas cuestiones críticas y desarrollar un marco para que los terapeutas familiares aborden estas dificultades centrándose en cuatro dimensiones interrelacionadas: valores culturales, determinantes sociales de salud, trauma colectivo, y responsabilidad ética y moral de los terapeutas familiares. Teniendo en cuenta el hecho de que los terapeutas familiares pueden funcionar inconscientemente como los mejores aliados de un sistema económico y político que perpetúa el racismo institucionalizado y el clasismo, necesitamos utilizar un conjunto de principios, valores y prácticas que no sea solo paliativo o a posteriori, sino que genere en el trabajo político y psicoterapéutico una política de asistencia. Por lo tanto, es necesario un reclamo firme de promover y abogar por un continuo más amplio de la salud y un pensamiento crítico que prepare a los profesionales para responder a las dificultades de la equidad sanitaria, así como de la justicia económica y ambiental, si fuera necesario. Las cuestiones tratadas en este artículo son específicas de los Estados Unidos a pesar de su relevancia para la terapia familiar como área. Somos conscientes de no generalizar la realidad de los Estados Unidos para el resto del mundo, y reconocemos que las cuestiones tratadas en este artículo podrían contribuir al discurso internacional.

Feasibility of Targeting Hispanic Fathers and Children in an Obesity Intervention: Papás Saludables Niños Saludables.

Background: Hispanic children and men carry a high burden for obesity and associated medical conditions. Healthy Dads Healthy Kids was the first obesity prevention intervention targeting fathers and demonstrated weight loss among fathers and behavior change among fathers and children in Australia. The aim of this study was to assess the feasibility of a culturally adapted version of the program for Hispanic families, Papás Saludables Niños Saludables. Methods: A randomized waitlist controlled trial with a process evaluation was conducted to assess the feasibility of Papás Saludables Niños Saludables(NCT03532048). Fathers, their partner (mother), and one to three children were enrolled. A priori feasibility criteria were: (1) recruit 40 Hispanic fathers and their families in ≤4 months; (2) retain 80% of participants for pre- and postassessments; (3) maintain ≥70% attendance to the 10 sessions; (4) obtain 80% "excellent" or "good" satisfaction from participants; and (5) collect anthropometric and behavioral data on ≥75% of participants at baseline and follow-up. Results: The study enrolled 90% (n = 36) of the goal from one local pediatric clinic between May and August 2018; retained 75% of participants for postassessment; maintained 72% attendance among those who started the program; and achieved 100% "excellent/good" satisfaction ratings among the participating fathers and mothers. One hundred percent of participants had most anthropometric and behavioral data at baseline and 72% at follow-up. Conclusions: With oversampling and improvements in the recruitment strategies, Papás Saludables Niños Saludables is feasible for a randomized controlled clinical trial to address whether a father-targeted lifestyle program is efficacious among low-income Hispanic men and their children.

Cultural adaptation of 'Healthy Dads, Healthy Kids' for Hispanic families: applying the ecological validity model.

BACKGROUND: Healthy Dads Healthy Kids (HDHK) is a unique lifestyle obesity intervention for fathers and children that demonstrated weight loss among the fathers and behavior change among fathers and children in Australia. The program is gender-tailored to specifically target fathers for weight loss and 5-12 year old children for obesity prevention. The aim of this formative study was to examine an Expert Panel's and Hispanic Family Panel's perceptions about the program and suggestions for the cultural adaptation of HDHK for Hispanic families in southwestern US. METHODS: Forty-four Hispanic participants (22 fathers, 13 mothers and 9 children) made up the Family Panel. They participated in 1-5 study contacts (focus groups, online survey, and/or interviews). The scripts and qualitative guides assessed participants' perceptions of the HDHK content and material using the Ecological Validity Model. Studies were conducted in English or Spanish, depending on the preference of the participant. Focus groups and interviews were audio-recorded, transcribed, translated, and thematically coded. Findings were reviewed with the Expert Panel who helped inform the cultural adaptation. RESULTS: 80% of parents were foreign-born, 57% spoke only Spanish at home, and 60% did not graduate from high school. Several themes emerged to inform the cultural adaptation of the program. Parents agreed with the HDHK goals and recommended the program place greater emphasis on parenting and limiting children's screen time. Some mothers and fathers wanted greater mother engagement. Weekly videos and a Facebook group emerged as favorite alternative options to engage mothers. Greater promotion of familism (inclusion and impact on whole family) was recommended for the program goals and activities. Gender roles for mothers and fathers, and differences in how fathers interact with male and female children, emerged and should be considered in program activities. Several barriers to father engagement surfaced, including lack of time due to work schedules, physically demanding jobs, concerns of caring for children without mother, fathers' current fitness/weight, and lack of knowledge of how to eat more healthfully. The reading level of the HDHK materials was too high for some parents. CONCLUSION: Findings from these formative qualitative studies informed the cultural adaptation of HDHK for Hispanic families, to account for literacy level, cultural values, and barriers to participation and engagement.
