RESUMO

Human Pegivirus-1, typically regarded as a commensal virus, exhibits high prevalence in humans. Its frequency and impact on oncologic pediatric patients with febrile neutropenia (FN), a frequent chemotherapy complication, remains unexplored. In this study, we assessed HPgV-1 RNA prevalence in pediatric patients experiencing FN. Blood samples were collected from 30 children, 15 presenting FN and 15 comprising a control group of either undergoing treatment or in remission. Overall, HPgV-1 RNA was detected in 23.3 % of samples (26.7 % among FN patients and 20.0 % among those under treatment or in remission). Phylogenetic analysis unveiled HPgV-1 genotype 2 predominance among these samples, the most prevalent strain circulating in Brazil. Our findings prompt crucial inquiries into the role of HPgV-1 RNA in FN: is it an incidental finding and if it can influences this clinical entity? Further investigation is imperative to elucidate HPgV-1 implications in vulnerable patients cohorts, potentially informing new approaches and understanding viral dynamics in immunocompromised populations.

RESUMO

Invasive infections caused by non-albicans Candida are increasing worldwide. However, there is still a lack of information on invasive candidiasis (IC) in the pediatric setting, including susceptibility profiles and clonal studies. We investigated the clinical, epidemiologic, and laboratory characteristics of IC, possible changes in antifungal susceptibility profiles over time, and the occurrence of clonality in our tertiary children's hospital. We analyzed 123 non-duplicate Candida isolates from sterile sites of pediatric patients in a tertiary hospital in southern Brazil, between 2016 and 2021. Data on demographics, comorbidities, and clinical outcomes were collected. Candida species distribution, antifungal susceptibility profiles, biofilm production, and molecular epidemiology of isolates were assessed using reference methods. The range of IC incidence was 0.88-1.55 cases/1000 hospitalized patients/year, and the IC-related mortality rate was 20.3%. Of the total IC cases, 42.3% were in patients aged < 13 months. Mechanical ventilation, parenteral nutrition, and intensive care unit (ICU) admission were common in this group. In addition, ICU admission was identified as a risk factor for IC-related mortality. The main site of Candida spp. isolation was blood, and non-albicans Candida species were predominant (70.8%). No significant clonal spread was observed among isolates of the three most commonly isolated species, and 99.1% of all isolates were biofilm producers. Non-albicans Candida species were predominant in this study. Notably, clonal expansion and emergence of antifungal drug resistance were not observed in our pediatric setting.

RESUMO

Antibiotics are often prescribed inappropriately, either when they are not needed or with an unnecessarily broad spectrum of activity. This is a serious problem that can lead to the development of antimicrobial resistance (AMR). This study was conducted to assess the antibiotic prescribing pattern in pediatric patients hospitalized at a quaternary hospital in Nampula, Mozambique, using the WHO indicators and Framework as a reference. A retrospective study was conducted using secondary data obtained from medical records. The study population consisted of children aged 0-10 years who were hospitalized in a quaternary-level hospital ward in Nampula, Mozambique. The pattern of antibiotic prescriptions was assessed using indicators and the WHO classification of antibiotics into AWaRe categories. Descriptive statistics were applied. A total of 464 antibiotics were prescribed during the study. The age groups of 1-3 years and 28 days-12 months were prescribed more antibiotics. The most common antibiotics were ceftriaxone and crystallized penicillin, which were frequently prescribed for patients suffering from bronchopneumonia, gastroenteritis, and malaria. 74.8% of the antibiotics prescribed belonged to the Access group, while 23.7% belonged to the Watch group. There were no prescriptions of antibiotics from the Reserve group. The average number of antibiotics per prescription was 1.51 (SD ± 0.725). The percentage of antibiotic prescribing was 97.5%, with 96.20% by injection. All antibiotics prescribed were on the essential medicines list and prescribed by generic name. These results are concerning and highlight the urgency of strengthening antimicrobial optimization measures, as well as implementing the AWaRe framework in antibiotic prescribing as an essential strategy to combat AMR.

RESUMO

Methotrexate (MTX), which presents high inter-individual variability, is part of the Brazilian Osteosarcoma Treatment Group (BOTG) protocol. This work aimed to develop a MTX population pharmacokinetic model (POPPK) for Brazilian children with osteosarcoma (OS) following the BOTG protocol to guide rescue therapy and avoid toxicity. The model was developed in NONMEM 7.4 (Icon®) using retrospective sparse data from MTX therapeutic drug monitoring of children attending a southern Brazilian public reference hospital. Data were described by a two-compartment model using 216 MTX cycles from 32 patients (5-18 y.o.) with OS who received 12 g/m2 dose/cycle. To explain inter-individual and inter-occasion variability in clearance and peripheral volume, covariates from demographic and biochemical data were evaluated. Serum creatinine was a significant covariate of MTX clearance (14.8 L/h), and the body surface area (BSA) was significant for central compartment volume (82.5 L). Inter-compartmental clearance and volume of peripheral compartment were 0.178 L/h and 5.72 L, respectively. The model adequately describes MTX exposure in Brazilian children with OS. Successful simulations were performed to predict MTX concentrations in pediatric patients above five years old with acute kidney injury and anticipate rescue therapy adjustments.

RESUMO

El cáncer es una de las causas de muerte más habitual por enfermedad en menores. Debido a los grandes avances en la investigación médica y los tratamientos, una gran tasa de niños la supera, de ahí que la promoción, prevención y tratamiento constituye un reto necesario a asumir a partir del análisis de sus dimensiones. El objetivo del trabajo es diseñar un sistema de actividades psicoterapéuticas para el perfeccionamiento de la atención a los pacientes oncológicos en el Hospital Provincial Pediátrico de Camagüey. La metodología empleada fue la cuanticualitativa (análisis de documentos, entrevista, encuestas, observación, entre otros). Se fundamentan teóricamente los elementos conceptuales, se exponen los asuntos psicosociales y didácticos de su diseño, así como la valoración por especialistas. Los resultados introducidos en la práctica desde la Sala de Oncología fueron apreciados favorablemente por los pacientes y familiares en 10 sesiones que incluyeron temas como la autoestima y asertividad.

Cancer is one of the most common causes of death due to illness in children. Due to the great advances in medical research and treatments, a large percentage of children overcome it, hence promotion, prevention and treatment constitute a necessary challenge to assume based on the analysis of its dimensions. The objective of the work is to design a system of psychconapeutic activities to improve care for oncological patients at the Provincial Pediatric Hospital of Camagüey. The methodology used was quantitative (document analysis, interview, surveys, observation, among cons). The conceptual elements are theoretically based, the psychosocial and didactic issues of its design are exposed, as well as the assessment by specialists. The results introduced into practice from the Oncology Ward were favorably appreciated by patients and family members in 10 sessions that included topics such as self-esteem and assertiveness.

RESUMO

Multidrug resistance (MDR) commonly leads to cancer treatment failure because cancer cells often expel chemotherapeutic drugs using ATP-binding cassette (ABC) transporters, which reduce drug levels within the cells. This study investigated the clinical characteristics and single nucleotide variant (SNV) in ABCB1, ABCC1, ABCC2, ABCC4, and ABCG2, and their association with mortality in pediatric patients with central nervous system tumors (CNST). Using TaqMan probes, a real-time polymerase chain reaction genotyped 15 SNPs in 111 samples. Patients were followed up until death or the last follow-up day using the Cox proportional hazards model. An association was found between the rs1045642 (ABCB1) in the recessive model (HR = 2.433, 95% CI 1.098-5.392, p = 0.029), and the ICE scheme in the codominant model (HR = 9.810, 95% CI 2.74-35.06, p ≤ 0.001), dominant model (HR = 6.807, 95% CI 2.87-16.103, p ≤ 0.001), and recessive model (HR = 6.903, 95% CI 2.915-16.544, p = 0.038) significantly increased mortality in this cohort of patients. An association was also observed between the variant rs3114020 (ABCG2) and mortality in the codominant model (HR = 5.35, 95% CI 1.83-15.39, p = 0.002) and the dominant model (HR = 4.421, 95% CI 1.747-11.185, p = 0.002). A significant association between the ICE treatment schedule and increased mortality risk in the codominant model (HR = 6.351, 95% CI 1.831-22.02, p = 0.004, HR = 9.571, 95% CI 2.856-32.07, p ≤ 0.001), dominant model (HR = 6.592, 95% CI 2.669-16.280, p ≤ 0.001), and recessive model (HR = 5.798, 95% CI 2.411-13.940, p ≤ 0.001). The genetic variants rs3114020 in the ABCG2 gene and rs1045642 in the ABCB1 gene and the ICE chemotherapy schedule were associated with an increased mortality risk in this cohort of pediatric patients with CNST.

RESUMO

BACKGROUND AND AIMS: The genetic epidemiology of inherited neuropathies in children remains largely unknown. In this study, we specifically investigated the genetic profile of a Brazilian cohort of pediatric patients with pure or complex axonal neuropathies, a crucial knowledge in the near future for establishing treatment priorities and perspectives for this group of patients. METHODS: Fifty-three pediatric patients who were assessed prior to reaching the age of 20, and who had clinical diagnoses of axonal hereditary neuropathy or presented with axonal neuropathy as the primary clinical feature, were included in the study. The recruitment of these cases took place from January 1, 2018, to December 31, 2020. The diagnosis was based on clinical and electrophysiological data. A molecular assessment was made using target-gene panel or whole-exome sequencing. Subsequently, segregation analysis was performed on available family members, and all candidate variants found were confirmed through Sanger. RESULTS: A molecular diagnosis was reached in 68% of the patients (n = 36/53), considering only pathogenic and probably pathogenic variants. Variants in MFN2 (n = 15) and GJB1 (n = 3) accounted for half of the genetically confirmed patients (50%; n = 18/36). The other 18 genetically diagnosed patients had variants in several less common genes. INTERPRETATION: Apart from MFN2 and GJB1 genes, universally recognized as a frequent cause of axonal neuropathies in most studied population, our Brazilian cohort of children with axonal neuropathies showed an important genetic heterogeneity, probably reflecting the multi ethnicity of the Brazilian population. Diagnostic, counseling, and future interventions should consider this characteristic.

RESUMO

Diagnosis of neuromuscular diseases (NMD) can be challenging because of the heterogeneity of this group of diseases. This review aimed to describe the diagnostic yield of whole exome sequencing (WES) for pediatric-onset neuromuscular disease diagnosis, as well as other benefits of this approach in patient management since WES can contribute to appropriate treatment selection in NMD patients. WES increases the possibility of reaching a conclusive genetic diagnosis when other technologies have failed and even exploring new genes not previously associated with a specific NMD. Moreover, this strategy can be useful when a dual diagnosis is suspected in complex congenital anomalies and undiagnosed cases.

RESUMO

Abstract Background: Women are the primary caregivers of children in palliative care. Research has shown that the presence of intimate partner violence at home exacerbates the vulnerability of the caregiver. Current statistics indicate a high prevalence of violence in Mexico present in the intersectionality between intimate partner violence and the role of the primary caregiver. This study aimed to describe the frequency of intimate partner violence among primary palliative caregivers at the Hospital Infantil de México Federico Gómez. Methods: We conducted a cross-sectional and prospective study with convenience sampling; no sample calculation was performed. All female primary caregivers of children in the palliative care unit were invited to participate. The Scale of Violence and Index of Severity of Violence was used as the measuring instrument. Results: One hundred women participated in the study by submitting their survey in a designated mailbox. No sociodemographic data or patient diagnoses were collected. The frequency of intimate partner violence was 28%, of which 16% were considered severe cases. Women reported psychological violence (36%), sexual violence (23%), and physical violence (22%). Conclusions: Almost one-third of female primary caregivers of pediatric patients at the Hospital Infantil de México Federico Gómez have been victims of some form of violence by current partners. This study highlights a previously unreported problem and opens the door for studies to correlate intimate partner violence among primary caregivers and the quality of life of children in palliative care.

RESUMO

The pulmonary manifestations of Systemic Lupus Erythematosus (SLE) in pediatric patients are poorly understood and the pulmonary manifestations reported from the adult population are generally extrapolated to the pediatric population. In the present work, the review of 228 files was carried out, in which the pulmonary manifestations, symptoms and antibody levels of the patients treated at the Hospital Regional de Alta Especialidad de Ixtapaluca (HRAEI), State of Mexico, Mexico, were identified. Statistical significance between groups was estimated using the Chi-square and Mann-Whitney U test. The main pulmonary manifestations identified were pleurisy (14 %), pulmonary hemorrhage (3.9 %), pulmonary thromboembolism (0.9 %), acute lupus pneumonitis (0.4 %), pulmonary arterial hypertension (0.4 %), and small lung syndrome (0.4 %). While the initial symptomatology was dyspnea with an incidence of 9.6 %, the mean oxygen saturation in the population was 96.87 %. Pleural effusion was identified as the most frequent pulmonary manifestation in radiographic changes. No statistically significant difference was found in antibody levels when comparing the groups. The most common pulmonary manifestation associated with SLE is pleurisy, however, the range of pulmonary manifestations in this type of patient can be very varied, as well as the presentation of each of them.

RESUMO

Aquellos casos en que se excede la fórmula dentaria normal primaria de 20 dientes o definitiva de 32 dientes se conocen como dientes supernumerarios o hiperodoncia. Los supernumerarios se pueden presentar de manera única o múltiple y de forma heteromórfica o eumórfica. El supernumerario más prevalente es el mesiodens, se da más en hombres, en dentición permanente y en el maxilar. Su etiología no está confirmada, pero puede deberse a una hiperactividad de la lámina dental. El tratamiento varía de acuerdo a cada paciente según si está afectando a la dentición normal o no y el desarrollo que tengan las estructuras dentarias. El siguiente reporte de caso habla de un paciente de 6 años, no sindrómico, en donde se presentó con un mesiodens erupcionado y se encontraron más supernumerarios gracias a la radiografía complementaria.

Those cases in which the primary normal dental formula of 20 teeth or the final one of 32 teeth is exceeded are known as supernumerary teeth or hyperdontia. The supernumeraries can be presented in a single or multiple way and in a heteromorphic or eumorphic way. The most prevalent supernumerary is the mesiodens, it occurs more in men, in the permanent dentition and in the maxilla. Its etiology is not confirmed, but it may be due to hyperactivity of the dental lamina. The treatment varies according to each patient depending on whether it is affecting the normal dentition or not and the development of the dental structures. The following case report talks about a 6-year-old, non- syndromic patient, who presented with an erupted mesiodens and more supernumeraries were found thanks to the complementary radiography.

RESUMO

To date, the treatment for cysticercosis and neurocysticercosis consists of a single oral intake of praziquantel (5-10 mg/kg), which since it is only available as tablets, hinders its administration to pediatric patients. Praziquantel is a poorly water-soluble drug which represents a challenge for its formulation in solution, particularly for the pediatric population. Thus, this study aimed to develop a palatable solution for praziquantel using pharmaceutical-accepted co-solvent systems. A design of experiments approach was applied to identify the optimal conditions for achieving a suitable amount of praziquantel in solution using co-solvent mixtures. Thus, praziquantel solubility increased from 0.38 up to 43.50 mg/mL in the optimized system. A taste masking assay in healthy human volunteers confirmed a successful reduction of drug bitterness after the addition of selected flavors and a sweetener. Stability studies were also conducted at different temperatures (4, 25, and 40 °C) for 12 months Even though the presence of the three known impurities of praziquantel was observed, their amounts never exceeded the acceptance criteria of the USP. Thus, this novel approach should be considered a valuable alternative for further preclinical studies considering the high prevalence of this infection worldwide.

RESUMO

OBJECTIVES: Methotrexate (MTX) is subject to therapeutic drug monitoring because of its high pharmacokinetic variability and safety risk outside the therapeutic window. This study aimed to develop a population pharmacokinetic model (popPK) of MTX for Brazilian pediatric acute lymphoblastic leukemia (ALL) patients who attended the Hospital de Clínicas de Porto Alegre, Brazil. METHODS: The model was developed using NONMEM 7.4 (Icon®), ADVAN3 TRANS4, and FOCE-I. To explain inter-individual variability, we evaluated covariates from demographic, biochemical, and genetic data (single nucleotide polymorphisms [SNPs] related to the transport and metabolism of drugs). RESULTS: A two-compartment model was built using 483 data points from 45 patients (0.33-17.83 years of age) treated with MTX (0.25-5 g/m2) in different cycles. Serum creatinine (SCR), height (HT), blood urea nitrogen (BUN) and a low BMI stratification (according to the z-score defined by the World Health Organization [LowBMI]) were added as clearance covariates. The final model described MTX clearance as [Formula: see text]. In the two-compartment structural model, the central and peripheral compartment volumes were 26.8 L and 8.47 L, respectively, and the inter-compartmental clearance was 0.218 L/h. External validation of the model was performed through a visual predictive test and metrics using data from 15 other pediatric ALL patients. CONCLUSION: The first popPK model of MTX was developed for Brazilian pediatric ALL patients, which showed that inter-individual variability was explained by renal function and factors related to body size.

RESUMO

BACKGROUND: The use of novel and accurate techniques to identify genetic variants (with or without a record in the National Center for Biotechnology Information (NCBI) database) improves diagnosis, prognosis, and therapeutics for patients with epilepsy, especially in populations for whom such techniques exist. The aim of this study was to find a genetic profile in Mexican pediatric epilepsy patients by focusing on ten genes associated with drug-resistant epilepsy (DRE). METHODS: This was a prospective, analytical, cross-sectional study of pediatric patients with epilepsy. Informed consent was granted by the patients' guardians or parents. Genomic DNA from the patients was sequenced using next-generation sequencing (NGS). For statistical analysis, Fisher's exact, Chi-square or Mann-Whitney U, and OR (95% CI) tests were performed, with significance values of p < 0.05. RESULTS: Fifty-five patients met the inclusion criteria (female 58.2%, ages 1-16 years); 32 patients had controlled epilepsy (CTR), and 23 had DRE. Four hundred twenty-two genetic variants were identified (71.3% with a known SNP registered in the NCBI database). A dominant genetic profile consisting of four haplotypes of the SCN1A, CYP2C9, and CYP2C19 genes was identified in most of the patients studied. When comparing the results between patients with DRE and CTR, the prevalence of polymorphisms in the SCN1A (rs10497275, rs10198801, and rs67636132), CYP2D6 (rs1065852), and CYP3A4 (rs2242480) genes showed statistical significance (p = 0.021). Finally, the number of missense genetic variants in patients in the nonstructural subgroup was significantly higher in DRE than in CTR (1 [0-2] vs. 3 [2-4]; p = 0.014). CONCLUSIONS: The Mexican pediatric epilepsy patients included in this cohort presented a characteristic genetic profile infrequent in the Mexican population. SNP rs1065852 (CYP2D6*10) is associated with DRE, especially with nonstructural damage. The presence of three genetic alterations affecting the CYP2B6, CYP2C9, and CYP2D6 cytochrome genes is associated with nonstructural DRE.

Introduction: the management of SARS-CoV-2 in pediatric patients by nursing professionals should be governed by the guidelines and protocols that the World Health Organization and the Ministry of Public Health have designed to minimize the complications and morbimortality rate that coronavirus can trigger. Objective: to analyze the management of SARS-CoV-2 in patients of the Pediatric Intensive Care Unit of Portoviejo Specialties Hospital, in Ecuador. Materials and methods: a cross-sectional, descriptive and quantitative research was carried out. The population consisted of 11 nursing professionals and 19 pediatric patients who were hospitalized with SARS-CoV-2 and who required ventilatory support. For data collection, a survey was carried out using Google Forms, in order to know the different procedures and review of clinical histories, as well as complications, ventilatory treatment and discharge. Results: 100% of the nursing staff used measures covered by the biosecurity protocols. In addition to the patients who required ventilatory support, 62.5% presented acute respiratory failure associated to COVID-19, compared to 37.5% who had symptoms of multisystem inflammatory syndrome. The deceased pediatric patients suffered from congenital diseases. Conclusions: the assistance of the nursing staff to the patients of the Pediatric Intensive Care Unit shows that knowledge acquired by these professionals achieved the restoration of the health of the children admitted there.

RESUMO

Abdominal compartment syndrome (ACS) has been the subject of increasing research over the past decade owing to its effects on morbidity and mortality in critically ill patients. This study aimed to determine the incidence and risk factors of ACS in patients in an onco-hematological pediatric intensive care unit in a middle-income country and to analyze patient outcomes. This prospective cohort study was conducted between May 2015 and October 2017. Altogether, 253 patients were admitted to the PICU, and 54 fulfilled the inclusion criteria for intra-abdominal pressure (IAP) measurements. IAP was measured using the intra-bladder indirect technique with a closed system (AbViser AutoValve®, Wolfle Tory Medical Inc., USA) in patients with clinical indications for indwelling bladder catheterization. Definitions from the World Society for ACS were used. The data were entered into a database and analyzed. The median age was 5.79 years, and the median pediatric risk of mortality score was 7.1. The incidence of ACS was 27.7%. Fluid resuscitation was a significant risk factor for ACS in the univariate analysis. The mortality rates in the ACS and non-ACS groups were 46.6% and 17.9%, respectively (P < 0.05). This is the first study of ACS in critically ill children with cancer.   Conclusion: The incidence and mortality rates were high, justifying IAP measurement in children with ACS risk factors.

RESUMO

BACKGROUND: Acute recurrent pancreatitis (ARP) and chronic pancreatitis (CP) are infrequent clinical entities in pediatric patients, as less than 8% of the literature mentions this population. This study aimed to describe the clinical and paraclinical profile, and the etiology related to patients with ARP and CP attended at a tertiary-level healthcare institute in Mexico. METHODS: We conducted a retrospective study from medical records of patients with ARP and CP attended between 2010 and 2020, analyzing the clinical characteristics, imaging studies, and the etiology associated with each patient. RESULTS: We analyzed 25 patients: 17 were diagnosed with ARP, and eight with CP. The main etiology identified was an anatomical alteration of the pancreatic duct (32%); pancreas divisum was the most prevalent condition. In 48% of the population, the etiology was not identified. The group with CP was higher in frequency for calcifications and dilation of the pancreatic duct (p < 0.005) compared to the ARP group. CONCLUSIONS: The main etiology for ARP and CP was an anatomical alteration of the pancreatic duct; however, in almost half of the cases, no established cause was identified. Although comparing our results with those offered by large cohorts such as the INSPPIRE group can be complex, we found relevant similarities. Currently, the data obtained from this first descriptive study are the foundation for future research in the field of Mexican pediatric pancreatology.

INTRODUCCIÓN: La pancreatitis aguda recurrente (PAR) y crónica (PC) son entidades poco frecuentes en la edad pediátrica; sin embargo, menos del 8% de la literatura hace referencia a esta población. El objetivo de este estudio fue describir el perfil clínico, paraclínico y etiologías vinculadas en los pacientes con PAR y PC atendidos en una institución de tercer nivel de atención en México. MÉTODOS: Se realizó un estudio retrospectivo de los expedientes de los pacientes con PAR y PC atendidos entre 2010 a 2020, analizando las características clínicas, estudios de imagen y etiologías asociadas en cada uno de los pacientes. RESULTADOS: Se analizaron 25 pacientes, 17 con diagnóstico de PAR y ocho con PC. La principal etiología identificada correspondió a las alteraciones anatómicas del conducto pancreático (32%); el páncreas divisum fue la entidad más prevalente. En el 48% de la población no se pudo identificar una etiología. El grupo con PC presentó mayor frecuencia de calcificaciones y dilatación ductal pancreática (p < 0.005) en comparación al grupo de PAR. CONCLUSIONES: La principal etiología de PAR y PC identificada en nuestro estudio corresponde a las alteraciones anatómicas del conducto pancreático; sin embargo, en casi la mitad de los casos, no se tiene una causa establecida. Aunque es complicado comparar nuestros resultados con los ofrecidos por las grandes cohortes del grupo INSPPIRE, sí encontramos similitudes relevantes. Los datos obtenidos en este primer estudio descriptivo son la base para futuras investigaciones en el ámbito de la pancreatología pediátrica mexicana.

RESUMO

Music-based interventions (MBI) in therapeutic routine have been observed as an effective tool for adjuvant therapy for patients with chronic diseases and for those with various types of disabilities. Music can serve as a pedagogical and therapeutic strategy for development of psychomotor skills in children and adolescents with long-lasting illnesses, and also as a secular way of promoting comfort and spiritual health for patients and families during difficult times; it can also be used to alleviate suffering during diagnostic and therapeutic procedures throughout the long recovery and/or rehabilitation processes. In this article, a musician and art therapist describes some simple MBI used daily in a tertiary children's hospital in Sao Paulo, where patients with chronic diseases and from lower socioeconomic background represent most of outpatients and inpatients. Some MBI developed or adapted by the author are described in detail, some of them using only the voice and others utilizing simple musical instruments, usually percussion ones, by the patients themselves. There are also reports describing MBI in special situations, such as long-lasting isolation of immunosuppressed patients (for bone marrow transplantation, for example), regular day-hospital visits for hemodialysis and religious songs for families of end-of-life or critically ill patients. In conclusion, MBI can be beneficial for improving patient experience in hospital settings, particularly for those with long-lasting or repeated stays, and can be performed in a simple and playful way, with contribution of other health professionals with some background in music, since music therapy specialists are still scarce in many countries.
