Repeated intravenous doses of human umbilical cord-derived mesenchymal stromal cells for bronchopulmonary dysplasia: results of a phase 1 clinical trial with 2-year follow-up.

BACKGROUND: Currently, there is a lack of effective treatments or preventive strategies for bronchopulmonary dysplasia (BPD). Pre-clinical studies with mesenchymal stromal cells (MSCs) have yielded encouraging results. The safety of administering repeated intravenous doses of umbilical cord tissue-derived mesenchymal stromal cells (UC-MSCs) has not yet been tested in extremely-low-gestational-age newborns (ELGANs). AIMS: to test the safety and feasibility of administering three sequential intravenous doses of UC-MSCs every 7 days to ELGANs at risk of developing BPD. METHODS: In this phase 1 clinical trial, we recruited ELGANs (birth weight ≤1250 g and ≤28 weeks in gestational age [GA]) who were on invasive mechanical ventilation (IMV) with FiO2 ≥ 0.3 at postnatal days 7-14. Three doses of 5 × 106/kg of UC-MSCs were intravenously administered at weekly intervals. Adverse effects and prematurity-related morbidities were recorded. RESULTS: From April 2019 to July 2020, 10 patients were recruited with a mean GA of 25.2 ± 0.8 weeks and a mean birth weight of 659.8 ± 153.8 g. All patients received three intravenous UC-MSC doses. The first dose was administered at a mean of 16.6 ± 2.9 postnatal days. All patients were diagnosed with BPD. All patients were discharged from the hospital. No deaths or any serious adverse events related to the infusion of UC-MSCs were observed during administration, hospital stays or at 2-year follow-up. CONCLUSIONS: The administration of repeated intravenous infusion of UC-MSCs in ELGANs at a high risk of developing BPD was feasible and safe in the short- and mid-term follow-up.

Outcomes of transcatheter pulmonary SAPIEN 3 valve implantation: an international registry.

BACKGROUND AND AIMS: Transcatheter pulmonary valve implantation (TPVI) is indicated to treat right-ventricular outflow tract (RVOT) dysfunction related to congenital heart disease (CHD). Outcomes of TPVI with the SAPIEN 3 valve that are insufficiently documented were investigated in the EUROPULMS3 registry of SAPIEN 3-TPVI. METHODS: Patient-related, procedural, and follow-up outcome data were retrospectively assessed in this observational cohort from 35 centres in 15 countries. RESULTS: Data for 840 consecutive patients treated in 2014-2021 at a median age of 29.2 (19.0-41.6) years were obtained. The most common diagnosis was conotruncal defect (70.5%), with a native or patched RVOT in 50.7% of all patients. Valve sizes were 20, 23, 26, and 29 mm in 0.4%, 25.5%, 32.1%, and 42.0% of patients, respectively. Valve implantation was successful in 98.5% [95% confidence interval (CI), 97.4%-99.2%] of patients. Median follow-up was 20.3 (7.1-38.4) months. Eight patients experienced infective endocarditis; 11 required pulmonary valve replacement, with a lower incidence for larger valves (P = .009), and four experienced pulmonary valve thrombosis, including one who died and three who recovered with anticoagulation. Cumulative incidences (95%CI) 1, 3, and 6 years after TPVI were as follows: infective endocarditis, 0.5% (0.0%-1.0%), 0.9% (0.2%-1.6%), and 3.8% (0.0%-8.4%); pulmonary valve replacement, 0.4% (0.0%-0.8%), 1.3% (0.2%-2.4%), and 8.0% (1.2%-14.8%); and pulmonary valve thrombosis, 0.4% (0.0%-0.9%), 0.7% (0.0%-1.3%), and 0.7% (0.0%-1.3%), respectively. CONCLUSIONS: Outcomes of SAPIEN 3 TPVI were favourable in patients with CHD, half of whom had native or patched RVOTs.

Seven Additional Patients with SOX17 Related Pulmonary Arterial Hypertension and Review of the Literature.

Pulmonary arterial hypertension (PAH) is an infrequent disorder characterized by high blood pressure in the pulmonary arteries. It may lead to premature death or the requirement for lung and/or heart transplantation. Genetics plays an important and increasing role in the diagnosis of PAH. Here, we report seven additional patients with variants in SOX17 and a review of sixty previously described patients in the literature. Patients described in this study suffered with additional conditions including large septal defects, as described by other groups. Collectively, sixty-seven PAH patients have been reported so far with variants in SOX17, including missense and loss-of-function (LoF) variants. The majority of the loss-of-function variants found in SOX17 were detected in the last exon of the gene. Meanwhile, most missense variants were located within exon one, suggesting a probable tolerated change at the amino terminal part of the protein. In addition, we reported two idiopathic PAH patients presenting with the same variant previously detected in five patients by other studies, suggesting a possible hot spot. Research conducted on PAH associated with congenital heart disease (CHD) indicated that variants in SOX17 might be particularly prevalent in this subgroup, as two out of our seven additional patients presented with CHD. Further research is still necessary to clarify the precise association between the biological pathway of SOX17 and the development of PAH.

Pulmonary Hypertension in Congenital Heart Disease: A Scientific Statement From the American Heart Association.

Patients with pulmonary hypertension associated with congenital heart disease make up an increasing proportion of the total pulmonary hypertension population who bring with them added complexity because of underlying anatomical and hemodynamic abnormalities. Currently, no consensus recommendations are available on how to best manage this group of patients for either the primary cardiologist or pulmonary hypertension subspecialist, including timing of referral. The purposes of this document are (1) to describe the various pulmonary hypertension groups and subgroups associated with congenital heart disease, (2) to describe imaging modalities used in patient evaluation, (3) to elucidate medical and surgical management considerations, (4) to highlight disparities within this population, and (5) to identify gaps and future research needs of patients with pulmonary hypertension associated with congenital heart disease.

Cyclodextrins Increase Triterpene Production in Solanum lycopersicum Cell Cultures by Activating Biosynthetic Genes.

In this work, Solanum lycopersicum cv. Micro-Tom suspension-cultured cells were used to analyze the effect of different elicitors including ß-cyclodextrins (CD), methyl jasmonate (MJ), ß-glucan (Glu) and 3-hexenol (Hex) separately and the combined treatments of CD + MJ, CD + glu and CD + Hex on triterpene compound production after 24, 72 and 96 h. Moreover, we studied the changes induced by elicitors in the expression of key biosynthetic genes to elucidate the regulation of the triterpene biosynthetic pathway. The relative abundance of the triterpene compounds identified in the extracellular medium after elicitation (squalene, fucosterol, avenasterol, ß-sitosterol, cycloartenol and taraxasterol) was determined by gas chromatography coupled to mass spectrometry, and the expression level of genes in treated-cells was analyzed by real-time quantitative polymerase chain reaction (qRT-PCR). Results showed that, in CD-treated cells (CD, CD + MJ, CD + Glu, CD + Hex), specialized metabolites were accumulated mainly in the extracellular medium after 72 h of elicitation. Moreover, qRT-PCR analysis revealed that the highest triterpene levels in CD-treated cells (CD, CD + MJ, CD + Glu, CD + Hex) were highly correlated with the expression of cycloartenol synthase, 3-hydroxy-3-methylglutaryl-CoA reductase and squalene epoxidase genes at 24 h of treatment, whereas the expression of sterol methyltransferase was increased at 72 h. According to our findings, CD acts as a true elicitor of triterpene biosynthesis and can promote the release of bioactive compounds from the tomato cells into the extracellular medium. The results obtained provide new insights into the regulation of the triterpene metabolic pathway, which might be useful for implementing metabolic engineering techniques in tomato.

Clinical Implications of the Genetic Background in Pediatric Pulmonary Arterial Hypertension: Data from the Spanish REHIPED Registry.

BACKGROUND: Pulmonary arterial hypertension (PAH) is a severe and rare disease with an important genetic background. The influence of genetic testing in the clinical classification of pediatric PAH is not well known and genetics could influence management and prognosis. OBJECTIVES: The aim of this work was to identify the molecular fingerprint of PH children in the REgistro de pacientes con HIpertensión Pulmonar PEDiátrica (REHIPED), and to investigate if genetics could have an impact in clinical reclassification and prognosis. METHODS: We included pediatric patients with a genetic analysis from REHIPED. From 2011 onward, successive genetic techniques have been carried out. Before genetic diagnosis, patients were classified according to their clinical and hemodynamic data in five groups. After genetic analysis, the patients were reclassified. The impact of genetics in survival free of lung transplantation was estimated by Kaplan-Meier curves. RESULTS: Ninety-eight patients were included for the analysis. Before the genetic diagnoses, there were idiopathic PAH forms in 53.1%, PAH associated with congenital heart disease in 30.6%, pulmonary veno-occlusive disease-PVOD-in 6.1%, familial PAH in 5.1%, and associated forms with multisystemic disorders-MSD-in 5.1% of the patients. Pathogenic or likely pathogenic variants were found in 44 patients (44.9%). After a genetic analysis, 28.6% of the cohort was "reclassified", with the groups of heritable PAH, heritable PVOD, TBX4, and MSD increasing up to 18.4%, 8.2%, 4.1%, and 12.2%, respectively. The MSD forms had the worst survival rates, followed by PVOD. CONCLUSIONS: Genetic testing changed the clinical classification of a significant proportion of patients. This reclassification showed relevant prognostic implications.

Clinical outcome of COVID-19 in patients with adult congenital heart disease.

AIMS: Patients with adult congenital heart disease (ACHD) are a potentially vulnerable patient cohort in case of COVID-19. Some cardiac defects may be associated with a poor COVID-19 outcome. Risk estimation in ACHD is currently based on expert opinion. The aim of this study was to collect clinical outcome data and to identify risk factors for a complicated course of COVID-19 in patients with ACHD. METHODS: Twenty-five ACHD centres in nine European countries participated in the study. Consecutive patients with ACHD diagnosed with COVID-19 presenting to one of the participating centres between 27 March and 6 June 2020 were included. A complicated disease course was defined as hospitalisation for COVID-19 requiring non-invasive or invasive ventilation and/or inotropic support, or a fatal outcome. RESULTS: Of 105 patients with a mean age of 38±13 years (58% women), 13 had a complicated disease course, of whom 5 died. In univariable analysis, age (OR 1.3, 95% CI 1.1 to 1.7, per 5 years), ≥2 comorbidities (OR 7.1, 95% CI 2.1 to 24.5), body mass index of >25 kg/m2 (OR 7.2, 95% CI 1.9 to 28.3) and cyanotic heart disease (OR 13.2, 95% CI 2.5 to 68.4) were associated with a complicated disease course. In a multivariable logistic regression model, cyanotic heart disease was the most important predictor (OR 60.0, 95% CI 7.6 to 474.0). CONCLUSIONS: Among patients with ACHD, general risk factors (age, obesity and multiple comorbidities) are associated with an increased risk of complicated COVID-19 course. Congenital cardiac defects at particularly high risk were cyanotic lesions, including unrepaired cyanotic defects or Eisenmenger syndrome.

Spanish registry of percutaneous VSD closure with NitOcclud Lê VSD Coil device: lessons learned after more than a hundred implants.

INTRODUCTION AND OBJECTIVES: The NitOcclud Lê VSD Coil was specifically designed for transcatheter occlusion of ventricular septal defects (VSD) and became available for this purpose in August 2010. Our objective was to describe the Spanish experience of this technique and analyze its reliability and short- to mid-term efficacy. METHODS: National multicenter observational study, which retrospectively recruited all patients (of any age) with VSD (of any location or type) who underwent percutaneous NitOcclud occlusion, using an intention-to-treat analysis, until January 2019. RESULTS: A total of 117 attempts were made to implant at least 1 NitOcclud in 116 patients in 13 institutions. The median [range] age and weight was 8.6 [0.4-69] years and 27 [5.8-97] kg, respectively. In 99 patients (85%), the VSD was an isolated congenital defect. The location was perimembranous in 95 (81%), and 74 (63%) of them were aneurysmatic. The mean fluoroscopy time was 34 [11.4-124] minutes. Of the 117 attempts, 104 were successful (89%) with a follow-up of 31.4 [0.6-59] months. At the last review, final complete occlusion of the defect without residual shunt or with only a minimal shunt was achieved in 92.3% (no shunt, n=73; trivial shunt, n=23). Four patients required a second procedure for residual shunt occlusion. Two devices had to be surgically explanted due to severe hemolysis. There were no deaths or other major complications. CONCLUSIONS: The NitOcclud device can be used successfully for a wide anatomical spectrum of VSD. The main issue is residual shunt, but its incidence decreases over time. The incidence of hemolysis was very low and no permanent changes were detected in atrioventricular conduction.

Abogacía por la salud de la población gitana: capacitación de profesionales del Distrito Sanitario Sevilla / Advocacy for Roma health: in-service training of professionals from the Seville Health District

Se describe la experiencia de un taller cuyo objetivo fue capacitar a profesionales para abogar por la salud de la población gitana. La abogacía por la salud es recomendada por organismos internacionales y expertos en salud pública para superar las inequidades en salud. Participaron 16 profesionales de tres centros de salud de barrios con una alta densidad de población gitana, en riesgo de exclusión social. El taller se organizó en tres sesiones dirigidas a sensibilizar, dar a conocer el marco conceptual y metodológico de la abogacía, y diseñar un plan de abogacía. Se pone de manifiesto la utilidad de este espacio de reflexión y análisis, y la necesidad de abogar por la salud de la población gitana, junto a otros agentes gitanos/as y sectores comunitarios, identificando oportunidades y utilizando los recursos comunitarios. Futuras investigaciones deben profundizar en el desarrollo de planes de abogacía intersectoriales y difundirlos, para facilitar su implementación en otros contextos de características similares

Pornography Influence Among Young Students: Adaptation and Validation of Pornography Consumption Inventory into Spanish.

This manuscript intends to adapt and validate Pornography Consumption Inventory (PCI) into Spanish in a sample of 211 young students who admitted to consume pornography. They completed a questionnaire that referred to sociodemographic characteristics, sexual behavior and PCI. Results showed a factorial structure of the scale with good data fit, composed of 13 items divided into three dimensions, i.e., emotional avoidance, sexual curiosity, and excitement seeking and sexual pleasure. These factors were positively interrelated and presented excellent internal consistency reliability. Some gender differences were observed, so that men presented higher scores in the three dimensions than women.

Implementing a cultural competence training as a psychopolitical empowerment process.

The cultural competence training (CCT) of health care professionals represents a useful resource to face the challenges involved in health care assistance for multicultural populations. However, the traditional perspective has shown limited results, as it does not consider professionals in their contexts and avoids continuous assessment processes. In response to these limitations, we describe a model of CCT implemented by two professors of the Faculty of Nursing at the University of Seville in Spain as a psychopolitical empowerment process, and exemplified by the experience of the emergency nurses at the Virgen Macarena Hospital. This process adds the notion of power to traditional CCT and uses dialogic learning to: (a) state a mission and develop critical thinking; (b) take stock of the actions for change and increase the capacity of nurses to respond; and (c) motivate nurses to plan the future and take action. As a result, professionals become a learning community, able to develop a new professional identity and role, and can also implement actions for the transformation of health care settings.

Pulmonary Vasodilators in the Management of Low Cardiac Output Syndrome After Pediatric Cardiac Surgery.

Pulmonary hypertension is among the causes of low cardiac output syndrome after neonatal and pediatric cardiac surgery. In the setting of transient postoperative myocardial dysfunction, even a moderate elevation of pulmonary pressure can result in heart dysfunction and circulatory collapse. Although, specific pharmacological manipulation of pulmonary vascular resistance is frequently required in the perioperative period, there is no widely standardized management. In this review, a systematic literature search of PubMed and MEDLINE databases using relevant terms was performed. All clinical trials and relevant manuscripts, along with important physiological, pharmacological, and evidence-based considerations involving the use of pulmonary vasodilators in the management of low cardiac output syndrome after cardiac surgery were reviewed. This article addresses the fifth of eight topics comprising the special issue entitled "Pharmacologic strategies with afterload reduction in low cardiac output syndrome after pediatric cardiac surgery".

Percutaneous interventions in Fontan circulation.

INTRODUCTION AND OBJECTIVES: Different percutaneous interventional procedures are needed to reach and maintain adequate anatomical and physiological conditions for the Fontan circulation. We aim to describe the experience gained at a children's hospital in such interventions, and to analyze the clinical outcomes. METHODS: Retrospective study of all patients with Fontan circulation completed between 1995 and 2013. We analyzed the clinical characteristics and the different types of percutaneous interventions performed, considering three different periods of time: before Glenn surgery, between Glenn and Fontan surgeries, and after Fontan was completed. Survival and time to indication of percutaneous interventions in each period were analyzed, as well as the clinical situation at last follow-up. RESULTS: Of the 91 patients analyzed, 46 (50.5%) required percutaneous interventions. The most frequent procedures were pulmonary artery angioplasty and angioplasty of the Fontan conduit. Estimated survival at 10, 20 and 30 years of age was 96.2%, 94.7% and 89.4%, respectively. There were no significant differences in survival of patients undergoing percutaneous interventions or not. Overall survival and time to indication of percutaneous interventions were significantly lower in the group of patients with right morphology systemic ventricle. Patients with fenestrated Fontan required interventions more frequently. At the end of follow-up, 66 patients (72.5%) were asymptomatic, without significant differences between patients who underwent or did not undergo percutaneous interventions. CONCLUSIONS: Interventional catheterization procedures are often necessary to reach and maintain the fragile Fontan circulation, mainly in patients with right morphology systemic ventricles and fenestrated Fontan conduits.

Nursing diagnosis of grieving: content validity in perinatal loss situations.

PURPOSE: To validate the content of the NANDA-I nursing diagnosis of grieving in situations of perinatal loss. METHODS: Using the Fehring's model, 208 Spanish experts were asked to assess the adequacy of the defining characteristics and other manifestations identified in the literature for cases of perinatal loss. FINDINGS: The content validity index was 0.867. Twelve of the 18 defining characteristics were validated, seven as major and five as minor. From the manifestations proposed, "empty inside" was considered as major. CONCLUSION: The nursing diagnosis of grieving fits in content to the cases of perinatal loss according to experts. IMPLICATIONS FOR NURSING PRACTICE: The results have provided evidence to support the use of the diagnosis in care plans for said clinical situation.
