Gender inequalities in prescribing and initiation patterns of guideline-recommended drugs after acute myocardial infarction

BackgroundEuropean guidelines recommend the prescription of certain drugs after acute myocardial infarction (AMI). The existence of gender differences in pharmacological treatment after an AMI has been described. This study aims to describe and analyse, using real-world data (RWD), whether there are gender differences in the prescribing patterns and initiation of treatment in secondary prevention after a first AMI, and which are the factors that explain these differences.MethodsA population-based observational study of RWD was conducted in the CARhES (CArdiovascular Risk factors for hEalth Services research) cohort. The study included subjects who had experienced a first episode of AMI between 2017 and 2022, had survived the event, and had a minimum follow-up of 180 days.Results3,975 subjects were followed 180 days after a first AMI. Women (27.8% of the study population) were older and had more comorbidities. Of the main guideline-recommended drugs, antiplatelets, lipid modifying agents and beta-blockers, were prescribed less often in women. Comedications such as rivaroxaban and calcium channel blockers were more likely to be prescribed in women. The proportion of subjects initiating treatment was similar in both genders.Overall, age and morbidity burden were the main contributors to differences in the prescribing patterns. Living in an urban area seemed to be a protective or mitigating factor. There were controversial results regarding socioeconomic level. ConclusionIn our study population, women are older, have greater comorbidities and lower socioeconomic status. Despite this, gender inequalities in the prescribing patterns after a first AMI remains, as women appear to experience less therapeutic effort. It is crucial to analyse them from an intersectional perspective, considering the influence of multiple axes of inequality on health, in order to develop gender-sensitive strategies with a multidisciplinary approach.

The Role of Insulin-Like Growth Factor (IGF-1) Signaling During Physical Exercise: A Systematic Review

Exercise is one of the non-pharmacological therapies that functions to improve public health. This study seeks to determine how increased IGF-1 levels during exercise as a hormone can trigger growth. For this study, a number of journal databases were searched, such as PubMed, Web of Science, Embase, and Science Direct. This study considers several aspects, such as research on exercise and IGF-1 published in reputable journals over the past five years. Our analysis only includes items published in reputable international journals. Using databases total of 159 publications were found. In this comprehensive analysis, about ten carefully selected and peer-reviewed papers were included. The standard operating procedure for this investigation was developed using Preferred Reporting Systematics and Meta-analysis (PRISMA). Based on the results of this systemic investigation, exercise has been shown to increase IGF-1 levels, a hormone that promotes growth. Physical exercise as a therapeutic effort and a means of improving public health.

Analysis of the therapeutic effort and economic cost of the care provided to a group of hospitalized end-of-life patients

AimThere are social inequalities in access to health care that affect therapeutic effort. The aim of the present study was to determine whether there are differences in expenditure according to days of admission and tests performed by age, sex and population of origin in patients at the end of life. MethodsCross-sectional descriptive study, with review of clinical histories of terminally ill patients admitted to a hospital, recruited on the basis of the administration of transfusions, who underwent numerous tests and interventions during their last admission before death. Sociodemographic and clinical variables were studied, as well as the cost of admission and tests. ResultsThe 140 patients were hospitalized for an average of 17.41 days (SD: 14.323), with an average cost of 8,264.19 euros (SD: 6,799.8788) per stay. They underwent 59 tests, which amounted to €532,209.68. Being male, of advanced age and of rural origin saw an increase in the number of days of admission. Older people and women received more tests. No relationship was found between days of hospitalization and expenditure with sociodemographic and clinical variables. There was a relationship between surgical interventions and sex (p = 0.047); between age and receiving oncological treatments (p < 0), other techniques (p < 0), nuclear medicine tests (p = 0.02) and electrocardiograms (p = 0.052). ConclusionsMany palliative patients die in hospitals receiving numerous tests that increase the number of days of hospitalization and costs. Advanced age determines hospital admissions, but not sex or population of origin.

Prognostic influence of the neurological complications in patients supported with venoarterial extracorporeal membrane oxygenation

Abstract Background Neurologic injuries including ischemic or hemorrhagic stroke and hypoxic-ischemic encephalopathy are common in patients supported with venoarterial extracorporeal membrane oxygenation (VA-ECMO). Purpose Our objective was to analyze the prognostic influence of neurological injuries on in-hospital survival. Methods Retrospective analysis of consecutive VA-ECMO cases in a referal center. We studied the neurological diagnoses and the results of complementary tests (brain computed tomography –CT- and electroencephalogram –EEG-) and their influence on in-hospital evolution. Results 238 VA-ECMO were implanted between oct 2013-jan 2024. Baseline, admission and evolution characteristics are collected in the table. 58.4% of patients had suffered cardiac arrest (prior to VA-ECMO implantation, and extracorporeal cardiopulmonary resuscitation was performed in 28.6% of cases. 6 (2.5%) suffered intracranial hemorrhage, 13 (5.5%) ischemic stroke and 40 (16.8%) some degree of hypoxic-ischemic encephalopathy. In-hospital survival was 32.4% (n=77). In 17.2% of the cases neurological damage influenced death (adequacy of therapeutic effort or non-escalation of therapies) and in 14.7% of cases death was directly due to neurological cause (table). Survival was lower in patients with ischemic (stroke survival 23.1% vs no stroke 33.2%, p=0.555) or hemorrhagic stroke (16.7% vs 33%, p=0.667), although without statistically significant differences. The presence of hypoxic brain damage was related to lower hospital survival (survival in patients with encephalopathy 15% vs. without 36.8%, p=0.009). Best EEG pattern registered was related to survival: I survival 33.3% and II 12.5% (good prognosis), III 25% (uncertain prognosis), IV 16.7% and V 0% (poor prognosis), p=0.048. The presence of status epilepticus showed a non-statistically significant trend towards lower survival (survival status 0% vs no estatus 25%, p=0.082). VA-ECMO preimplantation cardiac arrest was associated with the occurrence of encephalopathy (encephalopathy 84% vs. not 40%, p=0.049). The duration of cardiac arrest and lactate before VA-ECMO implantation were significantly higher as the EEG pattern was worse (figure). Conclusions Neurological damage is relevant in patients under VA-ECMO support, being a determining factor in death in up to 17.2% of patients. Hypoxic-ischemic encephalopathy was associated with lower survival, with the EEG pattern associated with previous cardiac arrest, its duration and lactate.Table.Baseline, admission and follow-upFigure.Cardiac arrest, lactate and EEG

Withdrawal/Withholding of Life-Sustaining Therapies: Limitation of Therapeutic Effort in the Intensive Care Unit.

Background/Objectives: The change in critically ill patients makes limitation of therapeutic effort (LTE) a widespread practice when therapeutic goals cannot be achieved. We aimed to describe the application of LTE in a post-surgical Intensive Care Unit (ICU), analyze the measures used, the characteristics of the patients, and their evolution. Methods: Retrospective observational study, including all patients to whom LTE was applied in a postsurgical ICU between January 2021 and December 2022. The LTE defined were brain death, withdrawal of measures, and withholding. Withholding limitations included orders for no cardiopulmonary resuscitation, no orotracheal intubation, no reintubation, no tracheostomy, no renal replacement therapies, and no vasoactive support. Patient and ICU admission data were related to the applied LTE. Results: Of the 2056 admitted, LTE protocols were applied to 106 patients. The prevalence of LTE in the ICU was 5.1%. Data were analyzed in 80 patients. A total of 91.2% of patients had been admitted in an emergency situation, and 56.2% had been admitted after surgery. The most widespread limitation was treatment withholding (83.8%) compared to withdrawal (13.8%). No differences were found regarding who made the decision and the type of limitation employed. However, patients with the limitation of no intubation had a longer stay (p = 0.025). Additionally, the order of not starting or increasing vasopressor support resulted in a longer hospital stay (p = 0.007) and a significantly longer stay until death (p = 0.044). Conclusions: LTE is a frequent measure in critically ill patient management and is less common in the postoperative setting. The most widespread measure was withholding, with the do-not-resuscitate order being the most common. The decision was made mainly by the medical team and the family, respecting the wishes of the patients. A joint patient-centered approach should be made in these decisions to avoid futile treatment and ensure end-of-life comfort.

Do not resuscitate orders and limitation of therapeutic effort: Ethical challenges in healthcare teams in Chile.

The purpose of this paper is to delve into the ethical aspects experienced by the healthcare team when they receive the directive to limit therapeutic effort or a do-not-resuscitate order. From an interpretative, qualitative paradigm with a content analysis approach, a process based on three phases was conducted: pre-analysis in which categories were identified, the projection of the analysis, and inductive analysis. During 2023, interviews were conducted in the clinical setting of a high-complexity hospital in Chile with 56 members of the healthcare teams from critical and emergency units, from which four categories emerged: a) the risk of violating patients' rights by using do-not-resuscitate orders and limiting therapeutic effort; b) the gap in the interpretation of the legal framework addressing the care and attention of patients at the end of life or with terminal illnesses by the healthcare team; c) ethical conflicts in end-of-life care; and d) efficient care versus holistic care in patients with terminal illness. There are significant gaps in bioethics training and aspects of a good death in healthcare teams facing the directive to limit therapeutic effort and not resuscitate. It is suggested to train personnel and work on a consensus guide to address the ethical aspects of a good death.

ETHICS COMMITTEES AND THEIR SOCIAL PROJECTION

Clinical ethics committees (CEC) fulfill three relevant functions: training in bioethics for mem­bers of the hospital community, participation in the institution’s ethical policies and guidelines, and advising clinical teams in resolving ethical problems. Both in Chile and in other countries, the function that demands the greatest dedication and that has been most evaluated in its impact is the consultative function. Thus, less time and effort are allocated to the educational task. In July 2023, a consultation was carried out to the CEC of public and private health institutions in Chile to find out the educational or training activities performed in the last 5 years. Of 83 queries sent, the response rate was 25%. A high percentage of those who responded (76%) had carried out at least one activity in the period, courses and conferences being the most frequent. There was a wide variety in the topics addressed, such as the adequacy of the therapeutic effort, exercise of autonomy, confidentiality, and end-of-life dilemmas, among others. Red de Salud UC CHRISTUS CEC stands out, because since 2016 has developed an annual conference with the objective of training and sharing experiences with members of other committees at the national level. It is concluded that it is necessary to continue promoting and evaluating the educational task of the CEC.

Mechanical circulatory support in high-risk PE for more than a decade

Abstract Funding Acknowledgements None. Background/Introduction Absence of solid evidence in clinical practice guidelines on the management of patients with a severe pulmonary thromboembolism (PTE) in a situation of cardiogenic shock requiring mechanical circulatory support (veno-arterial ECMO). A registry has been carried out in a tertiary hospital of patients admitted to the Cardiological Critical Care Unit (CCCU) with a diagnosis of high-risk PTE and V-A ECMO implantation. Purpose The objective is to describe the experience of our center due to the paucity of evidence from current guidelines in this area iin terms of morbimortality and expected outcomes. Methods Data were collected from all patients admitted with a diagnosis of high-risk PE in the CCCU from 05/01/2010 to 05/01/2023. Of these, only those in whom V-A ECMO was implemented during admission were analyzed and described below. Clinical, analytical and survival variables were explored. Results A total of 11 patients were included, 3 (27.27%) being women. The mean age was 53 years (SD 10.64). Every V-A ECMO cannulation was performed in a femoro-femoral configuration by a surgical approach. The mean length of stay in the Critical Care Unit, total hospital stay length and circulatory support time were respectively: 8 days (SD 5.5); 20.7 days (DS 16.5) and 3 days (DS 1.9). The indication for the implantation of V-A ECMO was in a situation of SCAI-E in 7 patients (in 2 of them, V-A ECMO was implanted during cardiac arrest, and a 100% of mortality was described in the first 24 hours). On the other hand, in the remaining 4 patients, the indication for support was a deteriorating evolution despite amines. Of these, in 2 of them, there was a formal contraindication for the administration of systemic fibrinolytic treatment (recent major surgery, in one of them oncology). It should be noted that VA ECMO without adjuvant fibrinolysis was used in 6 of the patients (54.5%), and in 1 of them (16%) of them died (anoxic encephalopathy). However, the remaining 5 patients received combined VA ECMO therapy and systemic fibrinolysis (45.5%), with 2 deaths reported in this subgroup (40%). Those deceases happened both due to adequacy of the therapeutic effort in the context of multiple organ failure. No major bleeding was reported, even in the combination therapy group. Conclusions Support with V-A ECMO has allowed survival &amp;gt;70% in patients diagnosed with high-risk pulmonary embolism, including in those cases with absolute contraindication for systemic fibrinolysis. High safety profile in terms of bleeding even in those patients with a combined approach.

Development of a new miniaturized system for ultrafiltration.

Acute decompensated heart failure and fluid overload are the most common causes of hospitalization in heart failure patients, and often, they contribute to disease progression. Initial treatment encompasses intravenous diuretics although there might be a percentual of patients refractory to this pharmacological approach. New technologies have been developed to perform extracorporeal ultrafiltration in fluid overloaded patients. Current equipment allows to perform ultrafiltration in most hospital and acute care settings. Extracorporeal ultrafiltration is then prescribed and conducted by specialized teams, and fluid removal is planned to restore a status of hydration close to normal. Recent clinical trials and European and North American practice guidelines suggest that ultrafiltration is indicated for patients with refractory congestion not responding to medical therapy. Close interaction between nephrologists and cardiologists may be the key to a collaborative therapeutic effort in heart failure patients. Further studies are today suggesting that wearable technologies might become available soon to treat patients in ambulatory and de-hospitalized settings. These new technologies may help to cope with the increasing demand for the care of chronic heart failure patients. Herein, we provide a state-of-the-art review on extracorporeal ultrafiltration and describe the steps in the development of a new miniaturized system for ultrafiltration, called AD1 (Artificial Diuresis).

The Impact of Clinical Ethics Consultations on Physicians in aLatin American Context.

Clinical bioethics plays a significant role in hospital settings through bioethics consultations, which focus on providing ongoing assistance in complex situations within the doctor-patient dynamic. These consultations entail regular interaction between physicians and clinical bioethicists. This situation prompts an exploration into how bioethics consultations affect physicians. The current research aims to understand the influence of bioethics consultations on physicians' bioethical knowledge by analyzing the lexical content in their patients' medical records. Medical records are a synthesis carried out by physicians, often reflecting collaborative efforts, and capturing verbal statements indicative of thought processes suggestive of learning. The study is a sequential mixed-methods design with a retrospective descriptive approach, comparing medical records from the early years of the Department of Humanism and Bioethics' operation (2013-2015) to the more recent ones (2019). Technical bioethical terminology such as "therapeutic effort limitation," "futility," "beneficence," and "respect for autonomy" is more prevalent in recent medical records. This trend may stem from the positive impact of bioethics consultations conducted by the Department, with haptic communication serving as a particularly effective form of interaction with others during experiences of moral distress. This appears to be characteristic of cultures like those in Latin America.

Adequacy of therapeutic effort: Challenges in pediatrics.

The term "therapeutic limitation" has been replaced by "adequacy of therapeutic effort" and is defined as the decision to withhold or withdraw diagnostic and therapeutic measures in response to the patient's condition, avoiding potentially inappropriate behaviors and redirectong treatment goals towards comfort and well-being. In the pediatric population, this decision is even more challenging given the nature of the physician-patient-family relationship and the paucity of guidelines to address treatment goals. The adequacy of therapeutic effort is framed by ethical and legal principles, but, in practice, there are several challenges. Each adequacy process is unique and dynamic, and should be addressed by taking into account with what measures, how, when, and in whom it should be implemented.

Exploring Advancements in the Treatment of Amyotrophic Lateral Sclerosis: A Comprehensive Review of Current Modalities and Future Prospects.

Amyotrophic lateral sclerosis (ALS) is a fatal and incurable disease requiring a multidisciplinary treatment approach and a collaborative therapeutic effort. A combination of both upper and lower motor neuron degeneration ultimately leads to respiratory failure, similar to other dementia-type neurodegenerative diseases. The aim of this paper is to pioneer current ALS research by carrying out a narrative literature review of the current treatment modalities of the disease. Through these efforts, we hope to condense the most pertinent information regarding current treatments and enhance the management of ALS patients as a whole, giving these patients a better quality of life as the search for a cure continues. We used a Pubmed search strategy and specific MeSH terms for the selection of the literature articles using the keywords "ALS," "new treatment," "treatment," and "symptomatic treatment." A combination of pharmaceutical interventions, psychological support, and physical rehabilitation has been most effective in enhancing the quality of life of patients with ALS (PALS). Among potential pharmacological therapies, only a few have been approved by the US Food and Drug Administration(FDA) to be used to treat ALS and its symptoms. Other treatment modalities being considered include gene therapy, cellular therapy, psychological therapy, physical therapy, and speech therapy, alongside robotics, alternative feeding methods, and communication devices.

Drug-Resistant Helicobacter pylori: Diagnosis and Evidence-Based Approach.

Helicobacter pylori (H. pylori) is the most common chronic bacterial infection, affecting approximately half of the world's population. H. pylori is a Class I carcinogen according to the World Health Organization, and the International Agency for Research on Cancer (IARC) has linked it to 90% of stomach cancer cases worldwide. The overall pattern points to a yearly reduction in eradication rates of H. pylori with the likelihood of success further decreasing after each unsuccessful therapeutic effort. Antimicrobial resistance in Helicobacter pylori is a major public health concern and is a predominant cause attributed to eradication failure. As a result, determining H. pylori's antibiotic susceptibility prior to the administration of eradication regimens becomes increasingly critical. Detecting H. pylori and its antimicrobial resistance has traditionally been accomplished by time-consuming culture and phenotypic drug susceptibility testing. The resistance of H. pylori to different antibiotics is caused by various molecular mechanisms, and advances in sequencing technology have greatly facilitated the testing of antibiotic susceptibility to H. pylori. This review will summarize H. pylori antibiotic resistance patterns, mechanisms, and clinical implications. We will also review the pros and cons of current antibiotic susceptibility testing methods. Along with a comparison of tailored susceptibility-guided regimens and empirical therapy based on the latest evidence, an evidence-based approach to such situations will be explored.

On the trail of Sisyphus - addiction as an existential neurosis?

In Greek mythology, Sisyphus, king of the Corinthians, dared to deceive the gods and was condemned to roll a boulder to the top of a mountain for all eternity. Shortly before reaching the summit, however, the boulder rolled back down into the valley, and the arduous task had to begin anew. Many of the contents of this classic myth are reminiscent of the therapeutic approach to addictive disorders. In addiction therapy, too, it is often a long and rocky road that ends with a relapse. The therapeutic effort was not entirely in vain, but one often begins to doubt its usefulness. In terms of Sisyphus and a Bio-Psycho-Social Model (BPSM) of health and disease, addiction can be located at the end of a downward spiral. By extension of the BPSM, can addictive disease be considered an expression of existential neurosis? The results of our own research speak in favor of this and show a clearly reduced experience of sense and meaning, but also diminished feelings of hope and forgiveness in addiction patients. However, positive correlations between various parameters of existential well-being and mental health or more appropriate stress coping are also found for the addiction group. These results are supported by neuronal correlates and are mirrored in the general population. Based on this, the consideration of existential issues in addiction therapy can be discussed. Finally, the use of art therapy and work training are proposed as examples of a meaning based therapeutic intervention in dealing with people with addictive diseases.

Melville's "Bartleby, the Scrivener: A Story of Wall-Street": The Vicissitudes of Treating a Difficult Patient.

Taking the liberty of imagining the lawyer in Melville's "Bartleby, the Scrivener" as narrator/therapist and Bartleby as patient, this article, written with the therapist/reader in mind, traces the vicissitudes of countertransference and speculates on what constitutes a "good enough" therapeutic effort.

MATHEMATICAL MODELING OF STEM CELL THERAPY FOR LEFT VENTRICULAR REMODELING AFTER MYOCARDIAL INFARCTION

The heart is an organ with a limited capacity for regeneration and repair. In this paper, a new mathematical model is presented to study the left ventricular remodeling after myocardial infarction (MI) and followed stem cell therapeutic effort. The model represents the post-MI regeneration process of cardiomyocytes under stem cell therapy with oxygen restoration. The resulting system of nonlinear ordinary differential equations (ODE) is studied numerically in order to demonstrate the functionality and performance of the new model. The optimal time of stem cell injection for various oxygen restorations is determined. Moreover, the regeneration of cardiomyocytes is successfully correlated with improved left ventricle function observed in experiments. The proposed nonlinear ODE model is able to capture the complicated biological interactions in post-MI remodeling and can serve as a platform for in silico simulation and perturbation to optimize MI stem cell therapy.

Experiences of parents of children with hypoplastic left heart syndrome during their treatment: a qualitative study.

To investigate the opinion and personal experience of parents of children born with Hypoplastic Left Heart Syndrome and what advice they would give to other parents who have to decide between treatment options. We conducted a qualitative, descriptive and retrospective study by means of a survey directed to parents of children born with Hypoplastic Left Heart Syndrome in a tertiary hospital in Buenos Aires (Argentina). Their answers and data regarding medical procedures were analysed. Parents of thirteen out of sixteen patients with Hypoplastic Left Heart Syndrome were surveyed. Norwood surgery had been performed in all the patients, many had received other procedures, and five had died. In relation to the decision-making process, sixty-one percent of parents would recommend other parents to remain at peace after having done everything possible and 54% would suggest to not feel guilt despite the final result. None of the parents would recommend rejecting surgical treatment and choosing comfort care. The majority of parents of children with Hypoplastic Left Heart Syndrome would recommend continuing with the therapeutic effort in order to feel at peace and reduce feelings of guilt.

THE EFFECT OF PRENATAL EXERCISE ON THE INCIDENCE OF POST PARTUM DEPRESSION

Background: The prevalence data for postpartum depression globally reaches 10-15%. In Asia alone, the incidence of postpartum depression reaches 26 - 85%. Meanwhile in Indonesia, the incidence rate is 50-70%. Various interventions are carried out to reduce the prevalence of postpartum depression. Currently, many studies have found the effectiveness of reducing the risk of postpartum depression by preventing routine exercise during pregnancy. Objective: To discuss the effectiveness of exercise during pregnancy compared to the incidence of postpartum depression. Method: This paper involved on referral sources and based on observation by author. Results: Exercise is a non- pharmacological therapeutic effort that is able to reduce stressors in the body, increasing self-confidence in pregnant women who regularly exercise so as to reduce the risk of depression both during pregnancy and after pregnancy. Apart from being related to the mother's own physical factors, there are psychosocial factors that arise when a mother joins regular exercise classes during pregnancy. namely having a strong form of support among pregnant women so that they do not feel alone in facing physical and psychological changes during pregnancy, childbirth, and postpartum There are psychosocial factors that arise when a mother participates in routine exercise classes during pregnancy. namely having a strong form of support among pregnant women so that they do not feel alone in facing physical and psychological changes during pregnancy, childbirth, and postpartum. Conclusion: Psychosocial factors that arise when a mother participates in routine exercise classes during pregnancy having a strong form of support among pregnant women so that they do not feel alone in facing physical and psychological changes during pregnancy, childbirth, and postpartum. Keywords: prenatal, exercise, post-partum depression.

Evaluation of Current Antiemetic Therapy Response in Patients Undergoing MEC or HEC Regimens in Portugal.

Chemotherapy-induced nausea and vomiting (CINV) negatively impact cancer patients' quality of life and treatment outcomes. This study evaluated the achievement of complete response to CINV prophylaxis during the first five days after chemotherapy in adult outpatient cancer clinics with solid malignant tumours receiving Moderate or Highly Emetogenic Chemotherapy (MEC or HEC) in Portugal. During the study, patients completed three evaluations, and nausea severity and CINV impact on patients' daily life was assessed. A complete response (no emetic episodes, no use of rescue antiemetic medication, and no more than mild nausea) was observed in 72% of the cycles (N = 161) throughout the five days after chemotherapy. Amongst the patient population, 25% classified their CINV episodes as severe. Though more than half of the patients achieved a complete response, suggesting that a therapeutic effort is being made to minimise this side effect, the overall scenario is barely optimistic. Significantly, new CINV-control measures in MEC/HEC patients should be adopted, specifically avoiding the single use of dexamethasone and 5-HT3 and raising awareness of using NK1-RAs. Thus, it is critical to improve CINV prophylactic treatment and implement practical international antiemetic guidelines in Portuguese clinical practice, envisaging the improvement of supportive care for cancer patients.

La muerte de los niños. Debates éticos en torno a la limitación del esfuerzo terapéutico

Ethical dilemmas take importance in current medical practice, especially at the end of life. Limitation of therapeutic effort, understood as not starting or withdrawing life support measures, is an alternative to preserve patient dignity when death approaches. Ethical dilemmas in this context have been widely studied in adults; not in children, in which the big psychological tension experienced by parents and professionals makes difficult to take accepted and consensual ethical decisions. The objective of this work has been to understand the concept of limitation of therapeutic effort and the deontological principles that support them in the pediatric field. The purpose was none other than to establish improvements in dying children whom peculiar life-end makes necessary a different approach of adults and an ethical conceptual clarification which justify LET practice in youngers.
