Understanding the dynamics of deceased organ donation and utilization in Colombia.

Objective: To obtain a comprehensive overview of organ donation, organ utilization, and discard in the entire donation process in Colombia. Methods: A retrospective study of 1 451 possible donors, distributed in three regions of Colombia, evaluated in 2022. The general characteristics, diagnosis, and causes of contraindication for potential donors were described. Results: Among the 1 451 possible donors, 441 (30.4%) fulfilled brain death criteria, constituting the potential donor pool. Families consented to organ donation in 141 medically suitable cases, while 60 instances utilized legal presumption, leading to 201 eligible donors (13.9%). Of those, 160 (11.0%) were actual donors (in whom operative incision was made with the intent of organ recovery or who had at least one organ recovered). Finally, we identified 147 utilized donors (10.1%) (from whom at least one organ was transplanted). Statistically significant differences were found between age, sex, diagnosis of brain death, and donor critical pathway between regions. A total of 411 organs were transplanted from 147 utilized donors, with kidneys being the most frequently procured and transplanted organs, accounting for 280 (68.1%) of the total. This was followed by 85 livers (20.7%), 31 hearts (7.5%), 14 lungs (3.4%), and 1 pancreas (0.2%). The discard rate of procured deceased donors was 8.1%. Conclusions: About one-tenth of donors are effectively used for transplantation purposes. Our findings highlight areas of success and challenges, providing a basis for future improvements in Colombia.

RESUMEN Objetivo. Presentar una descripción integral de la donación, utilización y descarte de órganos en todo el proceso de donación en Colombia. Métodos. Estudio retrospectivo de 1 451 donantes posibles, distribuidos en tres regiones de Colombia, que fueron evaluados en el 2022. Se describen las características generales, el diagnóstico y las causas de contraindicación de los donantes potenciales. Resultados. De los 1 451 donantes posibles, 441 (30,4%) cumplían con los criterios de muerte encefálica y constituyeron el conjunto de donantes potenciales. Las familias consintieron la donación de órganos en 141 casos aptos desde el punto de vista médico, mientras que en 60 casos se recurrió a la presunción legal, con lo que se llegó a 201 donantes aptos (13,9%). De estos, 160 (11,0%) fueron donantes reales (en los que se les practicó una incisión quirúrgica para la extracción de órganos o se obtuvo al menos un órgano). En última instancia, hubo 147 donantes utilizados (10,1%) (de los que se trasplantó al menos un órgano). Se observaron diferencias estadísticamente significativas entre las regiones en cuanto a edad, sexo, diagnóstico de muerte encefálica y vía crítica del donante. Se trasplantaron un total de 411 órganos procedentes de 147 donantes utilizados; los riñones fueron los órganos obtenidos y trasplantados con mayor frecuencia, ya que supusieron 280 (68,1%) del total de órganos, seguidos del hígado (85, 20,7%), el corazón (31 , 7,5%), los pulmones (14, 3,4%) y el páncreas (1, 0,2%). La tasa de descarte de los donantes fallecidos disponibles fue del 8,1%. Conclusiones. Aproximadamente una décima parte de los donantes son utilizados, de hecho, para realizar trasplantes. Estos datos destacan las áreas en las que se han obtenido buenos resultados y aquellas en las que se presentan desafíos, lo cual proporciona una base para futuras mejoras en Colombia.

Estudo retrospectivo de 1 451 possíveis doadores em três regiões da Colômbia que foram avaliados em 2022. Foram descritas as características gerais, o diagnóstico e os motivos para a contraindicação de potenciais doadores. Resultados. Dentre os 1 451 possíveis doadores, 441 (30,4%) preencheram os critérios de morte encefálica, formando o grupo de potenciais doadores. Em 141 casos considerados clinicamente aptos, as famílias consentiram com a doação de órgãos, e em 60 casos utilizou-se o princípio da presunção legal, resultando em 201 doadores elegíveis (13,9%). Desses, 160 (11,0%) foram doadores efetivos (ou seja, doadores nos quais foi feita uma incisão cirúrgica com a intenção de remover um órgão ou pessoas com pelo menos um órgão removido). Por fim, foram identificados 147 doadores utilizados (10,1%) (ou seja, que doaram pelo menos um órgão que foi transplantado). Foram encontradas diferenças estatisticamente significantes entre idade, sexo, diagnóstico de morte encefálica e itinerário crítico de doação entre as regiões. Um total de 411 órgãos foram transplantados de 147 doadores utilizados. Os rins foram os órgãos mais frequentemente removidos e transplantados, representando 280 (68,1%) do total, seguido de 85 fígados (20,7%), 31 corações (7,5%), 14 pulmões (3,4%) e 1 pâncreas (0,2%). A taxa de descarte de doadores falecidos com órgãos removidos foi de 8,1%. Conclusões. Cerca de um décimo dos doadores são efetivamente usados para fins de transplante. Nossos achados destacam áreas de sucesso e desafios, oferecendo uma base para futuras melhorias na Colômbia.

Alternativas de procesos para la búsqueda de casos de tuberculosis bajo condiciones económicas limitadas. Cuba 2022-2025 / Process Alternatives for the Tuberculosis Case Finding under Limited Economic Conditions. Cuba 2022-2025

Ejecutar procesos efectivos de búsqueda de casos de tuberculosis es crucial para acele-rar el paso hacia su eliminación. El empeoramiento de las condiciones económicas mun-diales y nacionales no nos permite aplicar extensivamente las tecnologías rápidas mo-leculares idóneas de diagnóstico. Consideramos sensato entonces aplicar algoritmos alternativos que satisfagan las necesidades nacionales presentes hasta que las condi-ciones permitan la cobertura completa de las tecnologías moleculares recomendadas. Sugerimos introducir la radiografía digital para todos los algoritmos, utilizar mejor la microscopía de fluorescencia LED y la óptica convencional ya probadas. En conclusión, es preciso que este enfoque de trabajo, que procura optimizar la efectividad y eficiencia del programa, se introduzca en la práctica cotidiana hasta que lo idóneo sea permisible

Executing effective tuberculosis case-finding processes is crucial to accelerate the path towards elimination of the disease. The worsening of global and national economic conditions do not allow us to extensively apply rapid molecular diagnostic technolo-gies. We consider it sensible and necessary to apply alternative algorithms that meet the current national needs, until conditions allow full coverage of the recommended molecular technologies. We suggest introducing digital X-rays for all algorithms, bet-ter use of LED fluorescence microscopy and conventional optics already appropriate-ly tested. In conclusion, it is necessary that this approach that seeks to optimize the effectiveness and efficiency of the Cuban program be introduced into daily practice until the ideal is permissible

A multidisciplinary approach reveals a new species of glassfrog from Colombia (Anura: Centrolenidae: Nymphargus).

Anurans of the family Centrolenidae are a highly diverse clade of Neotropical treefrogs. In the last two decades, glassfrogs have become a model system for studies in ecology and evolutionary biology, in part because their taxonomy and phylogenetic relationships are considered relatively well established. However, there are still many gaps in our knowledge, for example, which morphological characters are important for species delimitation. Consequently, several species complexes in Centrolenidae remain unresolved. Using data on external and internal morphology of adult individuals, tadpoles, advertisement call traits and genetic sequences, we describe a new species of glassfrog (Nymphargus pijao sp. nov.) endemic to Colombia that has been previously missasigned to Nymphargus griffithsi. We include in this description data of three phenotypic characters related to pectoral musculature and testis size, which have been traditionally overlooked in studies about the taxonomy and systematics of glassfrogs. In addition, we present details of a low-cost method implemented in the field to rear tadpoles of the new species. This methodology can solve common problems during the management and care of glassfrogs egg masses and tadpoles, and hence, promotes their description for more species and a better knowledge of the anuran biodiversity in Neotropics.

Factors Associated With Knowledge and Experience of Self-managed Abortion Among Patients Seeking Care at 49 US Abortion Clinics.

Importance: Patients attending US abortion clinics may consider or try self-managing their abortion before coming to the clinic, yet little is known about the factors associated with self-management behavior. Objective: To examine the prevalence and factors associated with considering or attempting a self-managed abortion before attending a clinic. Design, Setting, and Participants: This survey study included patients obtaining an abortion at 49 independent, Planned Parenthood, and academic-affiliated clinics chosen to maximize diversity in geographic, state policy, and demographic context in 29 states between December 2018 and May 2020. Data were analyzed from December 2020 to July 2021. Exposures: Obtaining an abortion at a clinic. Main Outcomes and Measures: Knowledge of medications used to self-manage an abortion, having considered medication self-management before attending the clinic, having considered any method of self-management before attending the clinic, and having tried any method of self-management before attending the clinic. Results: The study included 19 830 patients, of which 99.6.% (17 823 patients) identified as female; 60.9% (11 834 patients) were aged 20 to 29 years; 29.6% (5824 patients) identified as Black, 19.3% (3799 patients) as Hispanic, and 36.0% (7095 patients) as non-Hispanic White; 44.1% (8252 patients) received social services; and 78.3% (15 197 patients) were 10 weeks pregnant or less. Approximately 1 in 3 (34%) knew about self-managed medication abortion, and among this subsample of 6750 patients, 1 in 6 (1079 patients [16.1%]) had considered using medications to self-manage before attending the clinic. Among the full sample, 1 in 8 (11.7%) considered self-managing using any method before clinic attendance, and among this subsample of 2328 patients, almost 1 in 3 (670 patients [28.8%]) attempted to do so. Preference for at-home abortion care was associated with considering medication self-management (odds ratio [OR], 3.52; 95% CI, 2.94-4.21), considering any method of self-management (OR, 2.80; 95% CI, 2.50-3.13), and attempting any method of self-management (OR, 1.37; 95% CI, 1.10-1.69). Experiencing clinic access barriers was also associated with considering medication self-management (OR, 1.98; 95% CI, 1.69-2.32) and considering any method of self-management (OR, 2.09; 95% CI, 1.89-2.32). Conclusions and Relevance: In this survey study, considering self-managed abortion was common before accessing in-clinic care, particularly among those on the margins of access or with a preference for at-home care. These findings suggest a need for expanded access to telemedicine and other decentralized abortion care models.

Forgotten Heroes: Experiences of Health Care Support Workers Regarding Burnout and Resilience During Pandemic, A Qualitative Approach.

OBJECTIVES: Health care support workers have been facing several challenges due to the stressful environment in COVID-19 pandemic. Because of the gap in literature, it is mandatory to explore their experiences to identify burnout, predisposing factors, and possible interventions. METHODS: We conducted qualitative research with a hermeneutic phenomenological method. Participants belonged to cleaning services, security, and hospital administration areas at a hospital in Bogotá. We used semistructured individual interviews. The analysis approaches were deductive and inductive. RESULTS: As main concepts, we found the following: fear of infection and coping mechanisms, dealing with COVID-19 and being part of the health care support system, overwhelming workload and motivation to keep going and socioeconomic conditions. CONCLUSIONS: We found burnout predisposing factors; however, the participants did not express symptoms of burnout syndrome. We believe protective factors such as resilience are influential concerning this outcome.

Above- and below-ground trait coordination in tree seedlings depend on the most limiting resource: a test comparing a wet and a dry tropical forest in Mexico.

The study of above- and below-ground organ plant coordination is crucial for understanding the biophysical constraints and trade-offs involved in species' performance under different environmental conditions. Environmental stress is expected to increase constraints on species trait combinations, resulting in stronger coordination among the organs involved in the acquisition and processing of the most limiting resource. To test this hypothesis, we compared the coordination of trait combinations in 94 tree seedling species from two tropical forest systems in Mexico: dry and moist. In general, we expected that the water limitation experienced by dry forest species would result in stronger leaf-stem-root coordination than light limitation experienced by moist forest species. Using multiple correlations analyses and tools derived from network theory, we found similar functional trait coordination between forests. However, the most important traits differed between the forest types. While in the dry forest the most central traits were all related to water storage (leaf and stem water content and root thickness), in the moist forest they were related to the capacity to store water in leaves (leaf water content), root efficiency to capture resources (specific root length), and stem toughness (wood density). Our findings indicate that there is a shift in the relative importance of mechanisms to face the most limiting resource in contrasting tropical forests.

U.S. Abortion Care Providers' Perspectives on Self-Managed Abortion.

State-level restrictions on abortion access may prompt greater numbers of people to self-manage their abortion. The few studies exploring perspectives of providers towards self-managed abortion are focused on physicians and advanced practice clinicians. Little is known about the wider spectrum of abortion care providers who encounter self-managed abortion in their clinic-based work. To gain a deeper understanding of this issue and inform future care delivery, we conducted in-depth interviews with 46 individuals working in a range of positions in 46 abortion clinics across 29 states. Our interpretative analysis resulted in themes shaped by beliefs about safety and autonomy, and a tension between the two: that self-managed abortion is too great a risk, that people are capable of self-managing an abortion, and that people have a right to a self-managed abortion. Our findings highlight the importance of increasing knowledge and clarifying values among all abortion care providers, including clinic staff.

Evaluation of the effect of conventional and natural antifungals on motility and kinetics of cooled stallion semen.

Microbial growth in semen may cause a decline of sperm quality and fertility; however, the addition of antifungals to semen extender has been shown to impair the overall fertility of the sperm. The aim of this study was to evaluate the antifungal activity of conventional and natural compounds, and their effect on the motility and kinetics of cooled stallion semen. A total of 15 ejaculates from five stallions were collected using the artificial vagina. Each ejaculate was supplemented with: fluconazole at 12.5 (F1), 25 (F2) and 50 (F3) mg/ml; amphotericin-B at 6.5 (A1), 12.5 (A2) and 25 (A3) mg/ml (A3); clotrimazole at 12.5 (C1), 25 (C2) and 50 (C3) mg/ml; isoespintanol at 50 (I1), 100 (I2) and 150 (I3) µM; thymol at 50 (T1), 100 (T2) and 150 (T3) µM; and a control without supplementation. Motility and kinetics of semen at 0, 24 and 48 hr of cooling at 15°C were assessed using computer-assisted sperm analysis (CASA). At hour 48 of cooling, the antifungal effect of the treatments was evaluated. At hour 0 of cooling, amphotericin-B and I3 showed a reduction in most of the motility and kinetic parameters evaluated (p < .05). These treatments, and also C2 and C3, showed similar results at 24 and 48 hr of cooling. Thymol maintained motility and kinetics of the spermatozoa at all evaluated refrigeration times. Besides, I2 showed a decrease (p < .05) in the colony-forming unit compared to that in the control. It is concluded that thymol and isospintanol could be added as natural antifungals in extenders for stallion semen refrigeration.

Food Parenting Practices and Feeding Styles and Their Relations with Weight Status in Children in Latin America and the Caribbean.

While a growing body of literature looks at the associations between food parenting practices, and feeding styles, and child's weight status in developed countries, little is known for less developed countries, in general, and the Latin America and the Caribbean (LAC) region, in particular. This study systemically reviews and synthesizes existing evidence on the associations between child caregivers' food parenting practices and feeding styles and 2 to 12-year-old child weight status. Keywords were used to search in PubMed, Web of Science, PsycINFO, and Cumulative Index to Nursing and Allied Health Literature. Among the ten eligible articles, all of them reported significant associations between food parenting practices and feeding styles and child weight status. Existing studies have limitations, mainly related to cross-sectional convenience samples, which limit the generalization of the results. Additionally, small sample, heterogeneous feeding measures and weight related outcomes were other limitations. Future research is needed to understand caregiver-child interactions in the food situation and its link to child weight status in 2 to 12-year-old children in areas of LAC with diverse forms of malnutrition and contextual factors of countries.

Experiences seeking, sourcing, and using abortion pills at home in the United States through an online telemedicine service.

A growing number of people in the United States seek to self-manage their abortions by self-sourcing abortion medications online. Prior research focuses on people's motivations for seeking self-management of abortion and experiences trying to obtain medications. However, little is known about the experiences of people in the U.S. who actually complete a self-managed abortion using medications they self-sourced online. We conducted anonymous in-depth interviews with 80 individuals who sought abortion medications through Aid Access, the only online telemedicine service that provides abortion medications in all 50 U.S. states. Through grounded theory analysis we identified five key themes: 1) participants viewed Aid Access as a "godsend"; 2) Fears of scams, shipping delays, and surveillance made ordering pills online a "nerve-racking" experience; 3) a "personal touch" calmed fears and fostered trust in Aid Access; 4) participants were worried about the "what ifs" of the self-managed abortion experience; and 5) overall, participants felt that online telemedicine met their important needs. Our findings demonstrate that online telemedicine provided by Aid Access not only provided a critical service, but also offered care that participants deemed legitimate and trustworthy.

Factores predictores de aparición de fibrilación auricular en pacientes con miocardiopatía dilatada / Predicting factors of atrial fibrillation in patients with dilated cardiomyopathy

Resumen Introducción El uso de terapia anticoagulante en pacientes con miocardiopatía dilatada es controvertido. El riesgo hemorrágico hace que habitualmente no se use en pacientes en ritmo sinusal. Objetivo Analizar los factores predictores de fibrilación auricular (FA) en pacientes con miocardiopatía dilatada y fracción de eyección del ventrículo izquierdo (FEVI) < 40. Método: Se estudiaron los pacientes incluidos en el registro multicéntrico UMBRELLA a quienes se había implantado un desfibrilador (DAI) bicameral o tricameral y que presentaban miocardiopatía dilatada isquémica o no isquémica y FEVI < 40%. Se definió FA como cualquier episodio > 30 segundos de duración y una frecuencia auricular > 175 latidos por minuto. Resultados Se incluyeron 684 enfermos. La mediana de edad fue de 70 años (rango intercuartílico [RIQ]: 62-77). El 79.1% eran varones. La FEVI fue < 30% en el 76.3%. El 87.3% presentaban insuficiencia cardiaca (ICC) clínica. Se implantó un DAI resincronizador en el 59.5%. El 51.2% tenían bloqueo de rama izquierda del haz de His y el 7.1% de rama derecha (BRDHH). Se documentó FA en el 49% de los enfermos con una mediana de seguimiento de 29.93 meses (RIQ: 14.78-45.63). Las variables que se relacionaron con la aparición de FA fueron la presencia de ICC (hazard ratio [HR]: 2; intervalo de confianza del 95% [IC 95%]: 1.31-3.04; p = 0.001), el BRDHH (HR: 1.48; IC 95%: 1-2-18; p = 0.045), el ictus previo (HR: 2.11; IC 95%: 1.4-3.19; p < 0.001) y la edad > 75 años (HR: 1.21; IC 95%: 1.05-1.40; p = 0.008). Conclusiones La edad > 75 años, el BRDHH, la ICC y el ictus previo predicen la aparición de FA en la población con miocardiopatía dilatada y FEVI < 40%.

Abstract Introduction Anticoagulant treatment in patients with dilated cardiomyopathy and sinus rhythm is controversial due to haemorrhage risk. Objective To analyze the factors predicting atrial fibrillation (AF) in patients with dilated cardiomyopathy and ejection fraction (LVEF) < 40%. Method All patients included in UMBRELLA multicentre registry without AF, who had a dual or three-chamber implantable cardiac defibrillator (ICD), dilated cardiomyopathy and LVEF < 40% were included. AF was defined as any episode > 30 seconds of duration and atrial frequency > 175 bpm. Results 684 patients were included. Median age was 70 years (IQR 62-77); 79.1% were male. LVEF was < 30% in 76.3% of cases; 87.3% presented clinical heart failure (CHF). A CRT-D was implanted in 59.5%; 51.2% of patients presented Left Bundle Branch Block (LBBB) and 7.1% presented Right Bundle Branch Block (RBBB). AF was documented in 49% of patients, with a median follow-up of 29.93 months (IQR: 14.78-45.63). The presence of CHF (HR: 2; 95% CI: 1.31-3.04; p = 0.001), RBBB (HR: 1.48; 95% CI: 1-2-18; p = 0.045), previous stroke (HR: 2.11; 95% CI: 1.4-3.19; p < 0.001) and age > 75 years (HR: 1.21; 95% CI: 1.05-1.40; p = 0.008) were associated with diagnosis of AF. Conclusions Age > 75 years, RBBB, CHF and previous stroke are predictors of AF development in the population with dilated cardiomyopathy and LVEF < 40%.

Predictores e impacto de la adopción de programación basada en la evidencia en la incidencia de terapias del desfibrilador automático implantable / Predictors of adoption and impact of evidence-based programming on the incidence of implantable cardioverter-defibrillator therapies

Introducción y objetivos El estudio ADVANCE III mostró una reducción de terapias del desfibrilador automático implantable (DAI) con el empleo de tiempos de detección de arritmia prolongados. Se describe la adopción y el impacto de dicha estrategia en la incidencia de terapias del DAI. Métodos Estudio observacional retrospectivo de pacientes con implante de DAI Medtronic (2005-2016) en un registro multicéntrico (UMBRELLA-NCT01561144). Se describe la evolución de la adopción de programación ADVANCE en relación con: publicación del estudio, implementación de una campaña de formación y publicación de un consenso de expertos. Se identificaron con regresión logística los predictores de la adopción. Se comparó la incidencia de terapias en pacientes con y sin programación ADVANCE estimando la razón de tasas de incidencia ajustada (RTIa) mediante regresión binomial negativa. Resultados Se incluyó a 3.528 pacientes. Se utilizó la estrategia ADVANCE en el 20% del total y el 44% al final del estudio. La adopción se incrementó tras publicarse el estudio ADVANCE, y en menor grado tras la campaña de formación y consenso de expertos. Predictores de la adopción: DAI con detección nominal 30/40 (ORa=4,4; IC95%, 3,5-5,4), implantador electrofisiólogo (ORa=1,7; IC95%, 1,4-2,2) y prevención secundaria (ORa=3,2; IC95%, 2,6-3,9). El implante de DAI bicameral (ORa=0,6; IC95%, 0,5-0,8) o tricameral (ORa=0,5; IC95%, 0,4-0,7) se asoció con menor adopción. La programación ADVANCE se asoció con reducción de terapias totales (RTIa=0,77; IC95%, 0,69-0,86) y choques inapropiados (RTIa=0,66; IC95%, 0,52-0,85). Conclusiones La adopción de la programación ADVANCE es poco amplia y puede mejorarse mediante una adecuada selección de los parámetros nominales. Emplearla se asocia con una reducción de las terapias del DAI. (AU)

Introduction and objectives The ADVANCE III trial showed that a delayed-detection strategy reduces implantable cardioverter-defibrillator (ICD) therapies. Here, we describe the adherence to and predictors of ADVANCE adoption and compare ICD therapy rates between patients with and without ADVANCE programming. Methods This observational retrospective study analyzed patients implanted with Medtronic ICDs included from 2005 to 2016 in a Spanish national multicenter registry (UMBRELLA database; ClinicalTrials.gov, NCT01561144). Changes in ADVANCE programming adoption were described in relation to a) publication of the ADVANCE trial, b) implementation of an “ADVANCE awareness” campaign, and c) publication of an expert consensus statement. Multivariate logistic regression identified predictors of adoption. Therapy incidence rates were compared between groups by estimating the adjusted incidence rate ratio (aIRR) using negative binomial regression. Results A total of 3528 patients were included. An ADVANCE strategy was used in 20% overall and in 44% at the end of the study. ADVANCE III adoption increased after trial publication, with less growth after an “ADVANCE awareness” campaign and after expert consensus statement publication. Predictors of ADVANCE adoption were as follows: ICD device with a nominal number of intervals to detect 30/40 (aOR, 4.4; 95%CI, 3.5-5.4), implantation by an electrophysiologist (aOR, 1.7; 95%CI, 1.4-2.2), and secondary prevention (aOR, 3.2; 95%CI, 2.6-3.9). Dual-chamber ICDs (aOR, 0.6; 95%CI, 0.5-0.8) and cardiac resynchronization-defibrillators (aOR, 0.5; 95%CI, 0.4-0.7) were associated with lower adoption. ADVANCE programming was associated with reduced total therapy burden (aIRR, 0.77; 95%CI, 0.69-0.86) and fewer inappropriate shocks (aIRR, 0.66; 95%CI, 0.52-0.85). Conclusions ADVANCE adoption remains modest and can be improved through evidence-driven selection of nominal ICD settings. ... (AU)

Long-Term Outcomes Among a Nationwide Cohort of Patients Using an Implantable Cardioverter-Defibrillator: UMBRELLA Study Final Results.

Background Large-scale studies describing modern populations using an implantable cardioverter-defibrillator (ICD) are lacking. We aimed to analyze the incidence of arrhythmia, device interventions, and mortality in a broad spectrum of real-world ICD patients with different heart disorders. Methods and Results The UMBRELLA study is a prospective, multicenter, nationwide study of contemporary patients using an ICD followed up by remote monitoring, with a blinded review of arrhythmic episodes. From November 2005 to November 2017, 4296 patients were followed up. After 46.6±27.3 months, 16 067 episodes of sustained ventricular arrhythmia occurred in 1344 patients (31.3%). Appropriate ICD therapy occurred in 27.3% of study population. Patients with ischemic cardiomyopathy (hazard ratio [HR], 1.51; 95% CI, 1.29-1.78), dilated cardiomyopathy (HR, 1.28; 95% CI, 1.07-1.53), and valvular heart disease (HR, 1.94; 95% CI, 1.43-2.62) exhibited a higher risk of appropriate ICD therapies, whereas patients with hypertrophic cardiomyopathy (HR, 0.72; 95% CI, 0.54-0.96) and Brugada syndrome (HR, 0.25; 95% CI, 0.14-0.45) showed a lower risk. All-cause death was 13.4% at follow-up. Ischemic cardiomyopathy (HR, 3.09; 95% CI, 2.58-5.90), dilated cardiomyopathy (HR, 3.33; 95% CI, 2.18-5.10), and valvular heart disease (HR, 3.97; 95% CI, 2.25-6.99) had the worst prognoses. Delayed high-rate detection was enabled in 39.7% of patients, and single-zone programming occurred in 52.6% of primary prevention patients. Both parameters correlated with lower risk of first appropriate ICD therapy, with no excess risk of mortality. The rate of inappropriate shocks at follow-up was low (6%) and did not differ among type of ICD but was lower in SmartShock-capable devices. Conclusions Irrespective of the cause, contemporary ICD patients with heart failure-related disorders had a similar risk of ICD life-saving interventions and death. Current ICD programming recommendations still need to be implemented. Registration URL: https://www.clinicaltrials.gov; Unique identifier: NTC01561144.

Therapy incidence rates were compared between groups by estimating the adjusted incidence rate ratio (aIRR) using negative binomial regression. RESULTS: A total of 3528 patients were included. An ADVANCE strategy was used in 20% overall and in 44% at the end of the study. ADVANCE III adoption increased after trial publication, with less growth after an "ADVANCE awareness" campaign and after expert consensus statement publication. Predictors of ADVANCE adoption were as follows: ICD device with a nominal number of intervals to detect 30/40 (aOR, 4.4; 95%CI, 3.5-5.4), implantation by an electrophysiologist (aOR, 1.7; 95%CI, 1.4-2.2), and secondary prevention (aOR, 3.2; 95%CI, 2.6-3.9). Dual-chamber ICDs (aOR, 0.6; 95%CI, 0.5-0.8) and cardiac resynchronization-defibrillators (aOR, 0.5; 95%CI, 0.4-0.7) were associated with lower adoption. ADVANCE programming was associated with reduced total therapy burden (aIRR, 0.77; 95%CI, 0.69-0.86) and fewer inappropriate shocks (aIRR, 0.66; 95%CI, 0.52-0.85). CONCLUSIONS: ADVANCE adoption remains modest and can be improved through evidence-driven selection of nominal ICD settings. ADVANCE programming is associated with reduced therapy rates in real-world ICD recipients.

La familia es la voz del paciente en la interacción con la enfermera / A família como a voz do paciente na interação enfermeira-paciente / Family as the Patient's Voice in Nurse-Patient Interaction

Introducción: La familia experimenta un reto importante cuando uno de sus miembros está hospitalizado, pues los obliga a modificar sus dinámicas en términos de funciones y roles. Esta investigación cualitativa se realizó con familiares que acompañaron a uno de sus integrantes durante una experiencia de hospitalización; se consideró familia a quienes compartieran una historia en común con el paciente. Objetivo: Comprender el significado que le da la familia al papel que desempeña con el paciente en la interacción con las enfermeras durante el tiempo de hospitalización. Materiales y Métodos: Se utilizó el enfoque etnográfico. Se aplicaron 10 entrevistas a personas adultas. Se obtuvo información hasta lograr la saturación. Se tuvo en cuenta los criterios de rigor y los principios éticos. Resultados: La familia considera que tienen el derecho de ser la voz del paciente para interactuar con la enfermera, y la asume como una de sus funciones en su rol cuidador, para lograrlo es indispensable que ésta acuda al llamado, atienda, acompañe y brinde al paciente unos cuidados mínimos requeridos, relacionados primordialmente con la esfera física, de tal forma que en esa interacción demuestre su calidad humana, reconozca las necesidades del paciente y base su comunicación en la verdad y la cercanía. La familia espera una enfermera que los reconozca y los eduque, así mismo que les diga la verdad y se muestre cercana. Conclusiones: La familia se constituye en la voz del paciente como derecho connatural filial y en ese sentido, asume el cuidado del paciente con apoyo de las enfermeras, quienes tienen el deber de generar confianza y buen trato.

Introduction: Families experience a major challenge when a next of kin is admitted to hospital as family dynamics are forced to change in terms of duties and roles. Qualitative research has been conducted with family members who supported one of their next of kin during their hospitalization. Family members were defined as those who had shared a common history with patients. Objective: To understand the meaning given by families to the patient's voice role in the interaction with nurses during hospitalization. Materials and Methods: An ethnographic approach was used. Complete information was collected from 10 interviews with adults. Strict criteria and ethical principles were also applied. Results: Families consider that their right is to be the patient's voice to interact with nurses, assuming it as one of their caregiving functions. To this end, nurses must respond to the call, assist, accompany and provide patients with minimal care required, primarily related to physical care, so they can demonstrate their human qualities, recognize patients' needs and communicate on the basis of truth and closeness when interacting with patients. Families expect that nurses would recognize and instruct them, as well as tell the truth and be close to them. Conclusions: Families are the patient's voice as a matter of connatural right, assuming patients' care supported by nurses, who are in charge of building trust and providing good care.

Introdução: As famílias experimentam um grande desafio quando um parente próximo é hospitalizado, pois as dinâmicas familiares são forçadas a mudar em termos de deveres e papéis. Esta pesquisa qualitativa foi realizada com membros da família que acompanharam um de seus parentes durante a hospitalização. Os membros da família foram definidos como aqueles que tinham compartilhado uma história comum com os pacientes. Objetivo: Entender o significado dado pelas famílias ao papel da voz do paciente na interação com enfermeiros durante a hospitalização. Materiais e métodos: Uma abordagem etnográfica foi utilizada. Informações completas foram coletadas a partir de 10 entrevistas com adultos. Critérios rígidos e princípios éticos também foram aplicados. Resultados: As famílias consideram que tem o direito de ser a voz do paciente para interagir com enfermeiros, assumindo-a como uma de suas funções de cuidado. Para isso, os enfermeiros devem responder ao chamado, prestar assistência, acompanhar e prover aos pacientes os cuidados mínimos necessários, principalmente relacionados ao cuidado físico, para que possam demonstrar suas qualidades humanas, reconhecer as necessidades dos pacientes e se comunicar com base na verdade e na proximidade ao interagir com os pacientes. As famílias esperam que os enfermeiros os reconheçam e os instruam, assim como que digam a verdade e estejam próximos deles. Conclusões: As famílias são a voz do paciente como uma questão de direito conatural, assumindo os cuidados dos pacientes apoiados por enfermeiros, que são responsáveis por construir confiança e prestar bons cuidados.

Antitachycardia pacing for shock prevention in patients with hypertrophic cardiomyopathy and ventricular tachycardia.

BACKGROUND: Hypertrophic cardiomyopathy (HCM) carries an increased risk of sudden death due to ventricular arrhythmias (VAs). The implantable cardioverter-defibrillator (ICD) is a well-established therapy for treatment of VA. Monomorphic ventricular tachycardias (MVTs) are frequent in HCM patients and suitable for antitachycardia pacing (ATP) termination. OBJECTIVE: The purpose of this study was to describe ventricular tachycardia (VT) characteristics in a population of HCM patients with ICD and to study the effectiveness and safety of ATP for MVT. METHODS: Data were obtained from the multicenter prospective observational UMBRELLA trial, which included all patients with HCM and ICD followed by the CareLink Monitoring System. All episodes of VA were collected and analyzed. ATP effectiveness and safety were described, and factors related to ATP effectiveness were studied with generalized estimating equation (GEE) models. RESULTS: Among 251 patients followed for 47 months, 67 (26.7%) were implanted as secondary prevention. Fifty-six patients presented 326 episodes of VA (286 [87%] MVT). Mean cycle length was 312 ± 64 ms. Among 264 MVTs that received ICD therapy, 202 (76.5%) were ATP terminated. The first ATP burst was effective in 169 episodes (68.4%), and overall effectiveness of the first or second ATP burst was 73.8%. Multivariate GEE-adjusted analysis showed 2 variables related to ATP effectiveness: programming fast VT zone On vs Off (odds ratio [OR] 2.4; 95% confidence interval [CI] 1.5-5.2; P = .03) and programming ≥2 ATP bursts vs 1 burst only (OR 1.6; 95% CI 1.2-3.4; P = .04; and OR 2.9; 95% CI 1.8-6.3; P = .02; respectively). CONCLUSION: MVT is the predominant VA in HCM patients with ICD. ATP is highly effective in terminating the majority of MVTs, and its proved effectiveness should guide device selection and programming in order to avoid unnecessary high-energy shocks.
