The Database of European Forest Insect and Disease Disturbances: DEFID2.

Insect and disease outbreaks in forests are biotic disturbances that can profoundly alter ecosystem dynamics. In many parts of the world, these disturbance regimes are intensifying as the climate changes and shifts the distribution of species and biomes. As a result, key forest ecosystem services, such as carbon sequestration, regulation of water flows, wood production, protection of soils, and the conservation of biodiversity, could be increasingly compromised. Despite the relevance of these detrimental effects, there are currently no spatially detailed databases that record insect and disease disturbances on forests at the pan-European scale. Here, we present the new Database of European Forest Insect and Disease Disturbances (DEFID2). It comprises over 650,000 harmonized georeferenced records, mapped as polygons or points, of insects and disease disturbances that occurred between 1963 and 2021 in European forests. The records currently span eight different countries and were acquired through diverse methods (e.g., ground surveys, remote sensing techniques). The records in DEFID2 are described by a set of qualitative attributes, including severity and patterns of damage symptoms, agents, host tree species, climate-driven trigger factors, silvicultural practices, and eventual sanitary interventions. They are further complemented with a satellite-based quantitative characterization of the affected forest areas based on Landsat Normalized Burn Ratio time series, and damage metrics derived from them using the LandTrendr spectral-temporal segmentation algorithm (including onset, duration, magnitude, and rate of the disturbance), and possible interactions with windthrow and wildfire events. The DEFID2 database is a novel resource for many large-scale applications dealing with biotic disturbances. It offers a unique contribution to design networks of experiments, improve our understanding of ecological processes underlying biotic forest disturbances, monitor their dynamics, and enhance their representation in land-climate models. Further data sharing is encouraged to extend and improve the DEFID2 database continuously. The database is freely available at https://jeodpp.jrc.ec.europa.eu/ftp/jrc-opendata/FOREST/DISTURBANCES/DEFID2/.

Novelties in the pediatric cardiopulmonary resuscitation recommendations and lines of development in Spain.

OBJECTIVES: To analyse the 2020 international and European recommendations for Paediatric cardiopulmonary resuscitation (CPR), highlighting the most important changes and propose lines of development in Spain. METHODS: Critical analysis of the paediatric cardiopulmonary resuscitation recommendations of the European Resuscitation Council. RESULTS: The most relevant changes in the CPR recommendations for 2020 are in basic CPR the possibility of activating the emergency system after performing the five rescue ventilations with the mobile phone on loudspeaker, and in advanced CPR, bag ventilation between two rescuers if possible, the administration of epinephrine as soon as a vascular access is obtained, the increase in the respiratory rate in intubated children between 10 and 25 bpm according to their age and the importance of controlling the quality and coordination of CPR. In CPR training, the importance of training non-technical skills such as teamwork, leadership and communication and frequent training to reinforce and maintain competencies is highlighted. CONCLUSIONS: It is essential that training in Paediatric CPR in Spain follows the same recommendations and is carried out with a common methodology, adapted to the characteristics of health care and the needs of the students. The Spanish Paediatric and Neonatal Cardiopulmonary Resuscitation Group should coordinate this process, but the active participation of all paediatricians and health professionals who care for children is also essential.

Evaluation of Pediatric Immediate Life Support Courses by the Students.

A retrospective analysis was performed of 1637 questionnaires among students of immediate pediatric life support (IPLS) courses. All theory and practice classes and organization and methods received an average score higher than 8.5 except for the schedule and time devoted to developing contents. All parameters evaluating instructors' skills received a score higher than 9. Participants requested more time to practice and for course adaptation to their specific professionals needs. IPLS courses are highly valued by students. The duration of IPLS practice sessions should be increased and the course should be adapted to the specific professional needs of participants.

Evaluation of the pediatric life support instructors courses.

OBJECTIVE: To evaluate the results and quality of pediatric cardiopulmonary resuscitation (CPR) instructor training courses. METHODS: A retrospective analysis was performed of the results of 24 pediatric CPR instructor courses held over 21 years (1999 to 2019). The results of participants' evaluation of theory and practice sessions were analyzed. In addition, participants were asked to answer an anonymous survey to assess their opinion on the quality of theory and practice lessons, course organization and methodology, and instructor training. The results were compared by professional groups. RESULTS: A total of 560 participants completed the instructor course. Of them, 554 passed theory and practice tests (98.9 %). The mean score obtained in theory tests was 9.2 (0.8) out of 10. The mean score obtained in all practice tests was > 3.5 out of 5. Participants evaluated all the aspects of the course (theory and practice content, organization, teaching methodology, and instructors) with mean scores over 8 out of 10. CONCLUSIONS: Specific pediatric and neonatal CPR instructor courses are a cornerstone in the process of CPR training and ensuring the homogeneity and quality of training. Most of the participants obtained the qualification of instructors and their evaluation of the course was very positive.

Acute Myeloid Leukemia in Mexico: The Specific Challenges of a Developing Country. Results From a Multicenter National Registry.

BACKGROUND: In the past decades, long-term survival outcomes for younger patients with acute myeloid leukemia (AML) have improved. Nonetheless, developing nations might be lagging behind, highlighting the need to assess real-world outcomes in such regions. METHODS: We performed a multicenter retrospective study, which included patients with AML diagnosed between January 2013 and December 2017 from 13 centers in Mexico. RESULTS: A total of 525 patients with AML met the inclusion criteria and were included in the study. Median age for the entire cohort was 47 years. The patients were classified according to cytogenetic risk: favorable 16.0%, intermediate 55.6%, and unfavorable 28.4%. Most patients received intensive chemotherapy (80.2%), and among these 74.1% underwent a 7 + 3 induction regimen. A complete remission was achieved in 71.3% of patients. Induction-related mortality occurred in 17.8% and we identify the following as independent risk factors: >60 years (odds ratio [OR] 2.09 [1.09-4.02]), Eastern Cooperative Oncology Group >2 (OR 4.82 [2.46-9.43]), prior solid tumor (OR 3.8 [1.24-11.59]) and active infection (OR 1.82 [1.06-3.12]). Further, allogeneic hematopoietic stem-cell transplantation (AlloHSCT) was performed in 8.2% in CR1. The 3-year overall survival (OS) was 34.8%. In a multivariate analysis, several factors were independently associated with a worse OS, including secondary AML (hazard ratio [HR] 2.14 [1.15-4.01]) and unfavorable cytogenetic risk (HR 1.81 [1.16-2.82]), whereas maintenance therapy (HR 0.53 [0.32-0.86]) and AlloHSCT (HR 0.40 [0.17-0.94]) were associated with better OS. CONCLUSIONS: This is the first multicenter report analyzing AML survival in Mexico. Challenges in this setting include a high induction-related mortality and low AlloHSCT rate, which should be addressed to improve outcomes.

Comparison of the effect of three different protein content enteral diets on serum levels of proteins, nitrogen balance, and energy expenditure in critically ill infants: study protocol for a randomized controlled trial.

BACKGROUND: Nutritional support is essential in the care of critically ill children since malnutrition in this population is associated with increased morbidity and mortality. Injury in patients admitted to pediatric intensive care units (PICU) results in a catabolic state and augmented protein breakdown, leading to a negative protein balance. Current recommendations about protein prescription in the PICU are fundamentally based on expert opinions, and the minimum threshold is 1.5 g/kg per day of protein, although protein needs could be higher in certain subgroups of patients. The main objectives of the present study are to examine whether the administration of a protein-enriched infant formula increases the serum levels of total proteins, albumin, prealbumin, transferrin, and retinol and improves nitrogen balance and to analyze the effect of the high-protein diet on energy expenditure. A secondary objective is to register possible secondary effects of the protein-enriched diet. METHODS: A multicenter prospective randomized controlled trial (RCT) will be performed in three hospitals. Patients meeting inclusion criteria will be randomly allocated to one of three enteral feeding formulae with different protein contents. Blood and urine test, nitrogen balance assessment, and energy expenditure testing by indirect calorimetry will be performed at the beginning of the nutrition regimen and at 24 h, 72 h and 5-7 days after initiation. The sample size for this trial is estimated to be 90 participants (about 30 participants in each group). The data analysis will be by intention to treat. DISCUSSION: This RCT will provide new data about the amount of protein needed to improve levels of serum protein and nitrogen balance, a surrogate of protein balance, in critically ill infants receiving enteral nutrition. TRIAL REGISTRATION: ClinicalTrials.gov identifier: NCT03901742 . Registered April 1, 2019 - Retrospectively registered.

Contrasting microbial community responses to salinization and straw amendment in a semiarid bare soil and its wheat rhizosphere.

Soil salinization is a major constraint of agriculture in semiarid ecosystems. In this study soil microcosms were applied to evaluate the impact of a lower- and higher-level salinization treatment of a pristine scrubland soil on the abundance of Bacteria, Archaea, and Fungi, and on prokaryotic diversity in bare soil and the rhizosphere of wheat assessed by qPCR and high-throughput sequencing of 16S rRNA gene amplicons. Furthermore, the impact of soil straw amendment as a salt-stress alleviation strategy was studied. While the low-level salinity stimulated plant growth, the seedlings did not survive under the higher-level salinity unless the soil was amended with straw. Without the straw amendment, salinization had only minor effects on the microbial community in bare soil. On the other hand, it decreased prokaryotic diversity in the rhizosphere of wheat, but the straw amendment was effective in mitigating this effect. The straw however, was not a significant nutrient source for the rhizosphere microbiota but more likely acted indirectly by ameliorating the salinity stress on the plant. Members of Proteobacteria, Actinobacteria, and Firmicutes were abundant among the bacteria that reacted to soil salinization and the straw amendment but showed inconsistent responses indicating the large physiological diversity within these phyla.

Paediatric cardiopulmonary resuscitation training program in Latin-America: the RIBEPCI experience.

BACKGROUND: To describe the design and to present the results of a paediatric and neonatal cardiopulmonary resuscitation (CPR) training program adapted to Latin-America. METHODS: A paediatric CPR coordinated training project was set up in several Latin-American countries with the instructional and scientific support of the Spanish Group for Paediatric and Neonatal CPR. The program was divided into four phases: CPR training and preparation of instructors; training for instructors; supervised teaching; and independent teaching. Instructors from each country participated in the development of the next group in the following country. Paediatric Basic Life Support (BLS), Paediatric Intermediate (ILS) and Paediatric Advanced (ALS) courses were organized in each country adapted to local characteristics. RESULTS: Five Paediatric Resuscitation groups were created sequentially in Honduras (2), Guatemala, Dominican Republican and Mexico. During 5 years, 6 instructors courses (94 students), 64 Paediatric BLS Courses (1409 students), 29 Paediatrics ILS courses (626 students) and 89 Paediatric ALS courses (1804 students) were given. At the end of the program all five groups are autonomous and organize their own instructor courses. CONCLUSIONS: Training of autonomous Paediatric CPR groups with the collaboration and scientific assessment of an expert group is a good model program to develop Paediatric CPR training in low- and middle income countries. Participation of groups of different countries in the educational activities is an important method to establish a cooperation network.

[Current international recommendations for pediatric cardiopulmonary resuscitation: the European guidelines]. / Actualización de las recomendaciones internacionales de reanimación cardiopulmonar pediátrica (RCP): recomendaciones europeas de RCP pediátrica.

OBJECTIVES: This summary of the European guidelines for pediatric cardiopulmonary resuscitation (CPR) emphasizes the main changes and encourages health care professionals to keep their pediatric CPR knowledge and skills up to date. Basic and advanced pediatric CPR follow the same algorithm in the 2015 guidelines. The main changes affect the prevention of cardiac arrest and the use of fluids. Fluid expansion should not be used routinely in children with fever in the abuse of signs of shock because too high a volume can worsen prognosis. Rescue breaths should last around 1 second in basic CPR, making pediatric recommendations consistent with those for adults. Chest compressions should be at least as deep as one-third the anteroposterior diameter of the thorax. Most children in cardiac arrest lack a shockable rhythm, and in such cases a coordinated sequence of breaths, chest compressions, and administration of adrenalin is essential. An intraosseous canula may be the first choice for introducing fluids and medications, especially in young infants. In treating supraventricular tachycardia with cardioversion, an initial dose of 1 J/kg is currently recommended (vs the dose of 0.5 J/kg previously recommended). After spontaneous circulation is recovered, measures to control fever should be taken. The goal is to reach a normal temperature even before arrival to the hospital.

OBJETIVO: Este artículo resume las recomendaciones europeas de reanimación cardiopulmonar (RCP) pediátricas, destacando los principales cambios e intenta animar a los profesionales a actualizar y mantener sus conocimientos y habilidades en RCP pediátrica. Las recomendaciones europeas del año 2015 mantienen el mismo algoritmo de actuación en la RCP básica y avanzada pediátrica. Los cambios más significativos son: en la prevención de la parada cardiaca (PC), los niños con enfermedad febril sin signos de shock no deben recibir de forma rutinaria expansiones de fluidos porque un volumen excesivo puede empeorar el pronóstico. En la RCP básica se recomienda que la administración de la respiración dure alrededor de 1 segundo, para unificar las recomendaciones con las del adulto. En las compresiones torácicas el esternón debe deprimirse por lo menos un tercio del diámetro torácico anteroposterior. En el niño, la mayoría de las PC tienen ritmos no desfibrilables y en ellos la secuencia coordinada de ventilación y compresiones torácicas y administración de adrenalina es el tratamiento esencial. La vía intraósea, sobre todo en los lactantes, puede ser el acceso vascular de primera elección. En el tratamiento de la taquicardia supraventricular, cuando se realice cardioversión como tratamiento, se recomienda utilizar una dosis inicial de 1 J/kg (antes se recomendaba 0,5 J/kg). En los cuidados postresucitación tras la recuperación de la circulación espontánea, se deben tomar medidas para evitar la fiebre, teniendo como objetivo conseguir la normotermia ya desde el ámbito extrahospitalario.

Incidence and prognosis of nosocomial infection after recovering of cardiac arrest in children.

OBJECTIVE: to analyze the incidence of infection in children who have suffered an in-hospital cardiac arrest (CA) and the association with mortality. METHODS: A retrospective unicenter observational study on a prospective database with children between one month and 16 years old, who have suffered an in-hospital CA was performed. Clinical, analytical and monitorization data, treatment, mortality and cause of death were recorded. RESULTS: 57 children were studied (57.6% males). Recovery of spontaneous circulation (ROSC) was achieved in 50 children (87.7%) and 32 (59.3%) survived. After ROSC, 28 patients (56% of those who achieved ROSC) were diagnosed of infection. There were not significant differences in mortality between patients infected (42.9%) and uninfected (27.3%) p=0.374. Only one died in consequence of a sepsis with multiorganic failure. CONCLUSIONS: The frequency of infection in children after recovering of a cardiac arrest is high. There were no statistically significant differences in mortality between patients with and without infection after ROSC.

[The latest in paediatric resuscitation recommendations]. / Novedades en las recomendaciones de reanimación cardiopulmonar pediátrica.

Cardiac arrest has a high mortality in children. To improve the performance of cardiopulmonary resuscitation, it is essential to disseminate the international recommendations and the training of health professionals and the general population in resuscitation. This article summarises the 2015 European Paediatric Cardiopulmonary Resuscitation recommendations, which are based on a review of the advances in cardiopulmonary resuscitation and consensus in the science and treatment by the International Council on Resuscitation. The Spanish Paediatric Cardiopulmonary Resuscitation recommendations, developed by the Spanish Group of Paediatric and Neonatal Resuscitation, are an adaptation of the European recommendations, and will be used for training health professionals and the general population in resuscitation. This article highlights the main changes from the previous 2010 recommendations on prevention of cardiac arrest, the diagnosis of cardiac arrest, basic life support, advanced life support and post-resuscitation care, as well as reviewing the algorithms of treatment of basic life support, obstruction of the airway and advanced life support.

[Multiple organ failure after spontaneous return of circulation in cardiac arrest in children]. / Fallo multiorgánico tras la recuperación de la circulación espontánea en la parada cardiaca en el niño.

OBJECTIVE: To assess the frequency of the multiple organ failure and the prognostic value of multiple organ failure scores in children who have recovered from an in-hospital cardiac arrest. PATIENTS AND METHODS: A single centre, observational, and retrospective study was conducted on children between 1 month and 16 years old who suffered an in-hospital cardiac arrest and achieved return of spontaneous circulation (ROSC). In the first 24-48hours and between the fifth and the seventh day after ROSC, a record was made of the scores on paediatric severity (PRISM and PIM II) and multiple organ failure scales (PELOD and P-MODS), along with the clinical and analytical data, and including monitoring and treatment, mortality and cause of death. RESULTS: Of the total of 41 children studied, 70.7% male were male, and the median age was 38 months. The overall mortality during admission was 41.5%, with 14.6% dying in the first 48hours, and 7.6% in the following 3 to 5 days. In the first 48hours, clinical severity and multiple organ failure scores were higher in the patients that died than in survivors (PRISM 29 vs. 21) P=.125, PIM II (26.8% vs. 9.2%) P=.02, PELOD (21 vs. 12) P=.005, and P-MODS (9 vs. 6) P=.001. Between the fifth and seventh day, the scores on the four scales were also higher in patients who died, but only those of the PELOD (20.5 vs. 11) p=.002 and P-MODS (6.5 vs. 3) P=.003 reached statistical significance. CONCLUSIONS: Mortality in children after return of spontaneous circulation after cardiac arrest is high. The multiple organ failure after return of spontaneous circulation after cardiac arrest in children is associated with increased mortality.

Non-invasive mechanical ventilation after heart surgery in children.

BACKGROUND: The purpose of the study was to analyze the characteristics and evolution of non-invasive mechanical ventilation (NIV) in the postoperative period of heart surgery in children. METHODS: Retrospective observational study including all children requiring NIV after heart surgery in a single center pediatric intensive care unit (PICU) between 2001 and 2012. Demographic characteristics, ventilation parameters and outcomes were registered, comparing the first 6 years of the study with the last 6 years. RESULTS: 935 children required invasive or non-invasive mechanical ventilation, of which 200 (21.4) received NIV. The median duration of NIV was 3 days. Mortality rate was 3.9%. The use of NIV increased from 13.2% in the first period to 29.2% in the second period (p <0.001). Continuous positive airway pressure (CPAP) was the most common modality of NIV (65.5%). The use of bilevel positive airway pressure mode (BIPAP) increased from 15% in the first period to 42.9% in the second period (p < 0.001). The nasopharyngeal tube was the most common interface (66%), but the use of nasal cannula increased from 3.3 to 41.4% in the second period (p < 0.001). NIV failed in 15% of patients. The mortality rate did not change, the duration of NIV decreased and the PICU length of stay increased throughout the study. CONCLUSIONS: NIV is increasingly being used in the postoperative period of heart surgery in our center with an 85% success rate and is associated with a lesser need for invasive mechanical ventilation. CPAP was the most common modality and the "nasopharyngeal tube" was the most common interface in our study although, in the latter years, the use of BIPAP and nasal cannula has increased significantly.
