ABSTRACT Background: Driving pressure has been suggested to be the main driver of ventilator-induced lung injury and mortality in observational studies of acute respiratory distress syndrome. Whether a driving pressure-limiting strategy can improve clinical outcomes is unclear. Objective: To describe the protocol and statistical analysis plan that will be used to test whether a driving pressure-limiting strategy including positive end-expiratory pressure titration according to the best respiratory compliance and reduction in tidal volume is superior to a standard strategy involving the use of the ARDSNet low-positive end-expiratory pressure table in terms of increasing the number of ventilator-free days in patients with acute respiratory distress syndrome due to community-acquired pneumonia. Methods: The ventilator STrAtegy for coMmunIty acquired pNeumoniA (STAMINA) study is a randomized, multicenter, open-label trial that compares a driving pressure-limiting strategy to the ARDSnet low-positive end-expiratory pressure table in patients with moderate-to-severe acute respiratory distress syndrome due to community-acquired pneumonia admitted to intensive care units. We expect to recruit 500 patients from 20 Brazilian and 2 Colombian intensive care units. They will be randomized to a driving pressure-limiting strategy group or to a standard strategy using the ARDSNet low-positive end-expiratory pressure table. In the driving pressure-limiting strategy group, positive end-expiratory pressure will be titrated according to the best respiratory system compliance. Outcomes: The primary outcome is the number of ventilator-free days within 28 days. The secondary outcomes are in-hospital and intensive care unit mortality and the need for rescue therapies such as extracorporeal life support, recruitment maneuvers and inhaled nitric oxide. Conclusion: STAMINA is designed to provide evidence on whether a driving pressure-limiting strategy is superior to the ARDSNet low-positive end-expiratory pressure table strategy for increasing the number of ventilator-free days within 28 days in patients with moderate-to-severe acute respiratory distress syndrome. Here, we describe the rationale, design and status of the trial.

RESUMO Contexto: Em estudos observacionais sobre a síndrome do desconforto respiratório agudo, sugeriu-se que a driving pressure é o principal fator de lesão pulmonar induzida por ventilador e de mortalidade. Não está claro se uma estratégia de limitação da driving pressure pode melhorar os desfechos clínicos. Objetivo: Descrever o protocolo e o plano de análise estatística que serão usados para testar se uma estratégia de limitação da driving pressure envolvendo a titulação da pressão positiva expiratória final de acordo com a melhor complacência respiratória e a redução do volume corrente é superior a uma estratégia padrão envolvendo o uso da tabela de pressão positiva expiratória final baixa do protocolo ARDSNet, em termos de aumento do número de dias sem ventilador em pacientes com síndrome do desconforto respiratório agudo devido à pneumonia adquirida na comunidade. Métodos: O estudo STAMINA (ventilator STrAtegy for coMmunIty acquired pNeumoniA) é randomizado, multicêntrico e aberto e compara uma estratégia de limitação da driving pressure com a tabela de pressão positiva expiratória final baixa do protocolo ARDSnet em pacientes com síndrome do desconforto respiratório agudo moderada a grave devido à pneumonia adquirida na comunidade internados em unidades de terapia intensiva. Esperamos recrutar 500 pacientes de 20 unidades de terapia intensiva brasileiras e duas colombianas. Eles serão randomizados para um grupo da estratégia de limitação da driving pressure ou para um grupo de estratégia padrão usando a tabela de pressão positiva expiratória final baixa do protocolo ARDSnet. No grupo da estratégia de limitação da driving pressure, a pressão positiva expiratória final será titulada de acordo com a melhor complacência do sistema respiratório. Desfechos: O desfecho primário é o número de dias sem ventilador em 28 dias. Os desfechos secundários são a mortalidade hospitalar e na unidade de terapia intensiva e a necessidade de terapias de resgate, como suporte de vida extracorpóreo, manobras de recrutamento e óxido nítrico inalado. Conclusão: O STAMINA foi projetado para fornecer evidências sobre se uma estratégia de limitação da driving pressure é superior à estratégia da tabela de pressão positiva expiratória final baixa do protocolo ARDSnet para aumentar o número de dias sem ventilador em 28 dias em pacientes com síndrome do desconforto respiratório agudo moderada a grave. Aqui, descrevemos a justificativa, o desenho e o status do estudo.

RESUMEN Introducción: La musicoterapia puede ser utilizada para influenciar en el estado físico y emocional de pacientes diagnosticados con la COVID-19. Se realiza una revisión sistemática exploratoria que incluye estudios observacionales y ensayos clínicos; Pubmed y Scopus fueron las bases de datos empleadas para la realización de la búsqueda. Además, se incluyen registros de ensayos clínicos de la Plataforma de Registros Internacionales de Ensayos Clínicos de la Organización Mundial de la Salud. Objetivo: Explorar la literatura médica disponible, sobre el impacto clínico de la musicoterapia en pacientes diagnosticados con la COVID-19. Desarrollo: De 39 documentos encontrados se incluyen 2 artículos: un ensayo clínico y un reporte de caso, con una población total de 41 pacientes. Se encuentra evidencia médica que respalda el impacto clínico favorable sobre la saturación de oxígeno, rehabilitación física y síntomas asociados al estrés en pacientes con diagnóstico de la COVID-19 con y sin requerimiento de soporte ventilatorio. Conclusiones: La musicoterapia es una herramienta útil en el tratamiento y rehabilitación no farmacológica de pacientes con la COVID-19; sin embargo, son necesarios nuevos estudios clínicos con mayor número de poblaciones muestrales y mayor tiempo de seguimiento.

ABSTRACT Background: Music therapy can be used to influence the physical and emotional state of patients diagnosed with COVID-19. An exploratory systematic review was carried out including observational studies and clinical trials, Pubmed and Scopus were the databases used to carry out the literature search. In addition, clinical trial registries from the World Health Organization International Clinical Trials Registry Platform are included. Objective: To explore the available medical literature on the clinical impact of music therapy in patients diagnosed with COVID-19. Development: Of 39 documents found in the search, two articles are included: a clinical trial and a case report, with a total population of 41 patients. Medical evidence is found to support the favorable clinical impact on oxygen saturation, physical rehabilitation and symptoms associated with stress in patients diagnosed with COVID-19 with and without the need for ventilatory support. Conclusions: Music therapy is a useful tool in the non-pharmacological treatment and rehabilitation of patients with COVID-19. However, new clinical studies with a larger number of sample populations and follow-up times using music therapy in this disease are necessary.

Abstract: The present investigation analyzes the impact of the pandemic on consumers' preferences, within the framework of electronic commerce to recommend market strategies that focus on consumers with more digital attention. For this reason, Wilcoxon’s statistical comparison of related samples has been used for non-parametric data in order to perform a comparison of frequencies between groups of different times that measured the behavior of users in this same range. The survey was used as a research tool and an increase in online purchases could be evidenced, highlighting the use of credit or debit cards and a reduction in purchases in physical establishments. In the case of the perception of electronic commerce, there was an increase in the sensation of ease, need and greater degree of usefulness about it. The results obtained demonstrate that the pandemic had a significant impact on consumer behavior and perceptions of electronic commerce in the study group.

Resumen: La presente investigación analiza el impacto de la pandemia en las preferencias de los consumidores dentro del marco del comercio electrónico, busca recomendar estrategias de mercado que acerquen al consumidor hacia una atención más digital. Se hizo uso del estadístico de comparación de muestras relacionadas de Wilcoxon para datos no paramétricos, con el fin de realizar una confrontación de frecuencias entre grupos de distintos tiempos que midieron el comportamiento de los usuarios en este mismo intervalo. Se utilizó la encuesta como instrumento de investigación y se pudo evidenciar un incremento en las compras en línea, destacando el uso de las tarjetas de crédito o débito y una reducción de las compras en establecimientos físicos. En el caso de la percepción sobre el comercio electrónico existió un incremento en la sensación de facilidad, necesidad y mayor grado de utilidad sobre el mismo. Los resultados obtenidos demuestran que la pandemia generó un impacto significativo sobre el comportamiento del consumidor y las percepciones del comercio electrónico en el grupo de estudio.

Abstract The political changes that have taken place in Bolivia in the last fifty years have led to modifications in the participation of subalternized groups and changes in the ethical appreciation of life. This study aims to establish the bioethical behaviors of the Andean cosmovision in acculturated, endoculturated and transculturated people in La Paz, Bolivia. It is a mixed, exploratory, ethnographic, cross-sectional, comparative, synchronic, diachronic and systematic research, in which a questionnaire validated by experts (Cronbach’s alpha 0.932) was applied to 399 people (5.3% acculturated; 73.9%, endoculturated and 20.8%, transculturated). The results contrasted by hermeneutics obtained five categories, of which the category relationality was independent of acculturation (p=0.262); while the categories ecological awareness, complementarity, reciprocity, concept of health, social model and community depended on each other (p=0.000). It was found that the acculturated subjects from the rural area presented greater knowledge of ancestral ethics. The promotion of educational policies related to ethics is recommended. life Paz mixed exploratory ethnographic crosssectional, crosssectional cross sectional, sectional cross-sectional comparative synchronic research Cronbachs Cronbach s 0.932 0932 0 932 39 5.3% 53 5 3 (5.3 739 73 9 73.9% 208 20 8 20.8% transculturated. . transculturated) p=0.262 p0262 p 262 (p=0.262) awareness complementarity reciprocity health p=0.000. p0000 p=0.000 000 (p=0.000) recommended 0.93 093 93 5.3 (5. 7 73.9 2 20.8 p=0.26 p026 26 (p=0.262 p000 p=0.00 00 (p=0.000 0.9 09 5.

People with chronic conditions and elderly frequently use different levels of health care. If those are not coordinated, patients are exposed to complications and adverse effects. To avoid this, the implementation of transitional care (TC) is proposed, which includes the coordination and follow-up of users through the different care settings. We aimed to analyze the concept of transitional care, its characteristics and impact on people with chronic conditions. A search of articles published between 2012 and 2019 in Google Scholar, MEDLINE, CINAHL and Cochrane Library databases was conducted looking for articles related to the concept of transitional care, characteristics, and impact on people with chronic conditions. Several models of TC have been formulated and the literature identifies common interventions, namely telephone follow-up, outpatient clinics and home visits for self-management support. Reports show that TC reduces re-hospitalizations, care costs, increases quality of life and user satisfaction with the health system.

ABSTRACT “Communal Pots” (CP) are temporary social organizations that provide free food in times of crisis. In Chile, as a result of the COVID-19 pandemic, in 2020 the CP resurfaced and, although they have appeared in other periods of history, how they benefitted the population is unknown. The objective of this study is to determine the contribution of the CP to the diet and nutrition of Chileans, through the characterization and analysis of their food supply. For this, a descriptive study was carried out based on an online survey sent to volunteers from all over the country after signing the informed consent. The survey included characterization of the respondent and the CP they represented, the preparations offered by the CP, based on which the caloric and nutritional contribution was obtained. In total, 117 CP answered; 5.1% from the north, 85.5% from the center and 9.4% from the south of Chile. Their main contribution was providing lunches (95.9%) with a median of 150 (p25: 100 - p75: 200) daily rations, made up of a main entree (95.9%), bread (80.5%) and salad (74.8%). The most popular preparations were legumes (91.1%), rice (78%) and noodles (77.2%). These lunches provide an average of 23% of the daily energy requirement and 35% of the fiber requirement, but their contribution of vitamin B12 (2.5%), zinc (25%) and iron (28% req. woman) was low regarding the requirement and expected contribution for the meal time. To date, these data are the first published, to report on the real influence of this social movement in the country’s food security in times of crisis.

RESUMEN Las “ollas comunes” (OC) son organizaciones sociales temporales que entregan alimentación gratuita en periodos de crisis. En Chile, resurgen el año 2020 a raíz de la pandemia del COVID-19, y si bien han aparecido en otros períodos de la historia, no ha sido cuantificada su contribución. El objetivo de este estudio fue determinar su contribución a la alimentación y nutrición de las/os chilenas/os, mediante la caracterización y análisis de su oferta alimentaria. Se realizó un estudio descriptivo mediante la aplicación de una encuesta online a voluntarias/os de todo el territorio nacional, la cual incluyó una caracterización del encuestado/a, de la OC que representa y de las preparaciones ofrecidas, en base a lo cual se obtuvo el aporte calórico y nutricional. Contestaron 117 OC (5,1% zona norte, 85,5% centro y 9,4% sur) cuya contribución principal fue con almuerzos (95,9%) con una mediana de 150 (p25: 100 - p75: 200) raciones diarias, compuestas por plato de fondo (95,9%), pan (80,5%) y ensalada (74,8%). Las preparaciones más prevalentes fueron legumbres (91,1%), arroz (78%) y fideos (77,2%). Estos almuerzos aportaron en promedio un 23% del requerimiento energético diario y aportan con el 35% del requerimiento de fibra, pero su aporte en vitamina B12, zinc y hierro fue bajo respecto del requerimiento y aporte esperado para el tiempo de comida. Hasta la fecha, estos datos son los primeros publicados sobre el tema, siendo útiles para determinar su aporte a la seguridad alimentaria del país en tiempos de crisis.

PAHO/WHO proposes to implement the role of Advanced Practice Nurse (APN) in Latin America, to reduce gaps in coverage and access to health care. For this purpose, it is necessary to train nursing professionals with an expanded role, which allows them to collaborate in the diagnosis, treatment, and monitoring of people with specific diseases, under established protocols and clinical guidelines and within consolidated interdisciplinary health teams in a cost-effective way. One of the areas with the greatest coverage deficit in Latin America is adult oncology, with inequality in care opportunities for these patients. Part of the premature deaths attributable to this disease are due to the lack of access to timely diagnosis and treatment. As a contribution to the reduction of this gap, a training program of Advanced Nursing Practice was developed, addressing the most urgent needs in the field of oncology. The necessary competencies were defined to develop a professional-level master’s degree program, considering prevention, early detection, diagnosis, treatment, and monitoring of people with oncological diseases at different levels of care. A program of this kind is an opportunity to reduce the access gap and coverage of health care for people with cancer, improving their quality of life and their survival.

ABSTRACT: Osseointegrated implants are currently the prosthetic treatment by predilection in the oral cavity when dental organs have been lost. Bone deficiency interferes with the placement of these prosthetic attachments; To solve this lack of bone tissue in alveolar ridges, autologous, homologous or heterologous bone grafting techniques are proposed. The ultra-low speed drilling without irrigation, it is possible to collect autologous bone at the time of preparing the surgical site before placing the dental implant, which provides the best properties for bone regeneration without the need for another wound or more morbidity for the patient. We describe our ultra-low speed drilling protocol step by step, obtaining autologous bone from the same surgical site to rehabilitate small bone defects around the implant reducing comorbidities and surgical times.

Abstract The objective of this research is to analyze a test model of integrity and trust for the selection of human talent in organizations. To assess the reliability and validity of the test, two types of analysis were used. The first was done with classical theory models using the statistics Cronbach Alpha and Kuder-Richardson 2.0. The second is done using the Item Response Theory (IRT) through the Rasch model using the R software. The exam is done focusing on organizational psychopathy. The evidence shows reliability and validity in the analyzed, both for the questions and for the individuals examined. Rach model provides valuable information at the level of questions and subjects to have a better instrument. This research provides bidirectional knowledge i) in the personality tests applied in the organization and ii) by showing a methodology that can be used in any questionnaire to validate your answers.

Resumen El objetivo de esta investigación es analizar la validación y confiabilidad de un instrumento para la selección de capital humano en las organizaciones enfocado a la confianza-integridad. Para evaluar la confiabilidad y validez del instrumento se realizan dos tipos de análisis, el primero con modelos de la teoría clásica mediante el Alpha de Cronbach y el estadístico Kuder-Richardson 20. El segundo análisis se realiza utilizando la Teoría de Respuesta al Item (TRI) a través del modelo de Rasch, utilizando programación en R. El test desarrollado se realiza con enfoque en psicopatía organizacional. La evidencia encontrada muestra confiabilidad y validez en la prueba analizada, tanto para la valoración de las preguntas como para la fiabilidad en la selección de los individuos analizados.

Abstract Introduction: in Mexico the main problem in public health is obesity and other diseases that are associated whit this condition, including oral health. Objective: to evaluate the effect of metformin treatment in patients with class I obese on the activity of metalloproteinases present in periodontium with chronic periodontitis. Methods: a clinical study was conducted in 68 patients with class I obesity and periodontal disease. They were divided into 4 groups. 2 of them, in addition to the periodontal treatment, were administered metformin 850 mg per day for six weeks; 2 samples were taken per patient of periodontal tissue before and after each treatment, body mass index, plaque index and inflammation were measured. Acrylamide gel zymography was used to measure the activity of metalloproteinases in the sample of tissue collected. The data obtained were analyzed by descriptive statistics, student t for related samples and one-way ANOVA was performed considering p < 0.01 as statistically significant. Results: in the group of patients who were administered metformin at the end of the treatment, there was a decrease in the body mass index, the degree of inflammation and lower metalloproteinase activity, compared with the control group (65% vs 25%; < 0.01). Conclusions: treatment with metformin in patients with obesity class I and periodontal disease decreases BMI, improves the symptoms of chronic periodontitis and decreases the activity of metalloproteinases 1, 3, 8, V present in periodontium of these patients.

Resumen Introducción: el principal problema de salud pública en México es la obesidad y sus enfermedades asociadas, incluyendo las bucales. Objetivo: evaluar el efecto del tratamiento con metformina en pacientes obesos de clase I sobre la actividad de las metaloproteinasas presentes en el periodonto con periodontitis crónica. Métodos: se realizó un estudio clínico con 68 pacientes mujeres con obesidad de clase I y enfermedad periodontal. Se dividieron en 4 grupos; a 2 de ellos, además del tratamiento periodontal, se les administro metformina de 850 mg al día durante seis semanas. Se tomaron 2 muestras por paciente de tejido periodontal antes y después de cada tratamiento y se midió el índice de masa corporal (IMC), el índice de placa dentobacteriana y de inflamación. Mediante zimografía en gel de acrilamida se midió la actividad de las metaloproteinasas en la muestra de tejido recolectada. Los datos obtenidos fueron analizados mediante estadística descriptiva t de student para muestras relacionadas y se realizó ANOVA de una vía considerando p < 0,01 como estadísticamente significativa. Resultados: en el grupo de pacientes a las que se les administro metformina al final del tratamiento se observó una disminución del índice de masa corporal, del grado de inflamación y menor actividad de metaloproteinasas respecto al grupo control (65% frente a 25%; p < 0,01). Conclusiones: el tratamiento con metformina en pacientes con obesidad de clase I y enfermedad periodontal disminuye el IMC, mejora los síntomas de la periodontitis crónica y disminuye la actividad de las metaloproteinasas 1, 3, 8 y V presentes en el periodonto de estos pacientes.

ABSTRACT INTRODUCTION Population aging is a worldwide phenomenon. It is estimated that by 2050, one of five persons will be aged ≥60 years. In Chile, 15.8% of the population is now aged ≥60 years, and this figure will reach 30.7% by 2050. In 2006, a national program was implemented to provide assistive devices to older adults aged ≥65 years with limited mobility or difficulty performing activities of daily living. To date, there have been no assessments of the program’s effectiveness. OBJECTIVE Assess the effectiveness of an assistive devices policy in Chile on improving functional capacity of older adults aged ≥65 years, and beneficiaries’ perceptions of the services received, including changes in their quality of life. METHODS This was a before–after longitudinal study. A cohort of 309 persons was recruited, consisting of patients who received care at a public hospital in Santiago, Chile during 2014–2015. They were assessed before delivery of assistive devices, then followed for seven months, with repeated evaluations made in their homes. The following indicators were measured: functional capacity (Tinetti scale and Barthel Index); changes in perceived quality of life related to use of assistive devices; and other sociodemographic, clinical and protocol-compliance variables. A longitudinal analysis of before–after progress was carried out, as well as a description of service delivery and medical followup. RESULTS Sixty-eight percent of those surveyed were women; median age was 74 years, average schooling was 6 years, and 93% had low income (monthly income <US$398). Assistive devices increased independence in activities of daily living, improved mobility and perceived quality of life, and decreased fall risk and pain. One hundred percent felt satisfied with the service received, 91% were trained in use of the device, and delivery deadlines were met in 83% of cases, but only 2% were followed up. One negative aspect is that the program covers only 25% of estimated need. CONCLUSIONS This assistive device program helps improve functional capacity and perceived quality of life in vulnerable patients who are able to access it. It addresses a real need and is highly valued by patients. Although delivery schedules were fulfilled, followup care schedules were not.

ABSTRACT Dietary supplements have become the key to complement deficiencies in the occidental diet and therefore to reduce the incidence of oxidative stress related diseases. A bench-scale extraction procedure was studied to obtain a valuable product rich in phenolic compounds and antioxidant capacity from Pinot Noir grape cane enhanced by storage. Extraction solvent, cane-size, solid:liquid ratio, temperature, and extraction time, were systematically evaluated in order to obtain a natural functional product. Complete chemical characterization of a Pinot Noir grape cane extract produced under bench scale process is presented for the first time. Phenolic profiles of the extracts were characterized by HPLC-PDA-MS/MS and minerals by ICP-OES. Proteins, carbohydrates and lignins were also evaluated. The main phenolic compounds in the final product were stilbenoids, flavan-3-ols, procyanidins, and flavonols, with 6.53%, 4.84%, 2.11%, and 0.25%, respectively on a dry matter basis. Other chemical constituents were carbohydrates (27%), minerals (1%) and lignins (38.7%). The antioxidant capacity of the product was demonstrated using chemical assays (TEACABTS/CUPRAC and ORAC-FL) and endothelial cells model. The extract produced under the described bench scale process using grape cane enhanced by storage have a chemical composition and protecting capacities to be used in functional foods industry.

In this paper, multiwalled carbon nanotubes (MWCNTs) were synthesized by spray pyrolysis to be used later as material reinforcement in the production of MWCNTs/Al7075 aluminum composites. Both, MWCNTs and MWCNTs/Al7075 composites were microstructurally and mechanically characterized. Scanning electron microscopy (SEM) analysis shows MWCNTs formed by multiple layers rolled on themselves forming a tube shape with lengths up to 1300 µm and diameters ranging from 55 to 120 nm. MWCNTs were added to the aluminum matrix in different concentrations up to 3.0 wt%. Their dispersion in the aluminum matrix was carried out by ultrasonic/methanol method followed by high-energy mechanical milling process. The effect of MWCNTs on the morphology and mechanical behavior of composites were evaluated. Results indicate that a homogeneous dispersion of CNTs was obtained as a consequence of the dispersion routes used in the production of composites, observing no damage on their morphology. The mechanical behavior of the composites shows a noticeable improvement for MWCNTs concentrations above 2.0 wt%, with ductility similar to that found in the literature for the Al7075 commercial alloy.

Abstract: Introduction: Becoming a first-time father is an important change in the life of men and families. Studies on the subject show that these kinds of changes have the power to put life into perspective. Being an involved father has a deep meaning for the child and the family. Objective: To explore the experience of becoming a first-time father during the child first year of the life. Subjects and Methods: A qualitative systematic review was conducted in 2014 in three stages, based on the Joanna Briggs Institute Method for Qualitative Systematic Reviews (QSR). The stages used in this QSR were: establishing the question, determining the type of studies to be included, defining the evaluation criteria, and synthesizing the data. Papers that assessed clinical prognoses were considered such as first-time parenting experience and child care during the first year of life. Only primary qualitative studies including ethnography, phenomenology, narrative analysis, and action research were con sidered. Results: Three meta-syntheses were obtained from the analysis: 1) fatherhood adjustment process, 2) paternal role development, and 3) being an active father. The path towards adoption and the fulfillment of the paternal role is mediated by different processes that are consolidated during the child first year of life. Conclusions: The results support the idea that fathers want to be active parti cipants in the care of their children, that public policies should consider both parents equal in terms of their parenting responsibilities, and that the protection of the family and the family environment is a priority as a health promotion intervention.

Resumen: Introducción: Ser padre por primera vez es un cambio importante en la vida del hombre y la familia. Los estudios en torno al tema demuestran que este tipo de cambios tienen la capacidad de poner la vida en perspectiva. Ser un padre participativo tiene un significado profundo para el niño/a y la familia. Objetivo: Explorar la experiencia de ser padre por primera vez durante el primer año de la vida del hijo/a. Sujetos y Método: Se realizó una revisión sistemática cualitativa en 2014 en 3 etapas, basado en el Joanna Briggs Institute Method para Revisiones Sistemáticas Cualitativas (QSR). Las etapas usadas en este QSR fueron: establecimiento de la pregunta, determinar el tipo de estudios a in cluir, definir los criterios de evaluación, y realizar la síntesis de los datos. Se consideraron manuscritos que evaluaran los pronósticos clínicos: experiencia de ser padre por primera vez y cuidados del niños durante el primer año de vida. Solo estudios cualitativos primarios incluyendo estudios de etnografía, fenomenología, análisis de narrativa e investigación de acciones fueron considerados. Resultados: Se obtuvieron tres meta-síntesis del análisis: 1) proceso de ajuste a la paternidad; 2) desarrollo del rol paterno y 3) ser un padre activo. El camino hacia la adopción y el cumplimiento del rol paterno está mediado por diversos procesos que durante el primer año de vida del niño/a se consolidan. Conclu siones: Los resultados apoyan la propuesta de que los padres desean ser protagonistas del cuidado de sus hijos/as, que las políticas públicas deben considerar a ambos padres como iguales en términos de sus responsabilidades de crianza, y que la protección de la familia y el entorno familiar es una priori dad como intervención de promoción de salud.
