How can we improve the quality of health care in hospital attendance of medically complex children? / ¿Cómo podemos mejorar la calidad de la atención hospitalaria de los pacientes crónicos complejos en pediatría?

Hospital care of medically complex children (MCC) is increasing, although its real prevalence in Spain is unknown. OBJECTIVE: to analyze hospital admissions and outpatient follow-up of MCC in order to identify strategies to improve the quality of care of MCC. PATIENTS AND METHOD: An analytical, observational, and retrospective study was carried out. We included MCC who were admitted to Pediatric Hospitalization in the last 5 years, in a tertiary hospital without a specific unit for MCC. Clinical data related to their underlying pathology, outpatient visits, and hospital admissions were collected. A multivariate study was carried out to describe risk factors of the need for technological support and to predict prolonged admissions and the hospital consultation rate. RESULTS: 99 MCC (55.6% males) aged 3.9 (2-8) years were included. 41.4% of MCC required technological support at home and presented the highest number of comorbidities, hospital admissions, and care by different specialists (p < 0.01). Older MCC (p < 0.01) with underlying digestive disease (p < 0.04) and respiratory comorbidity (p < 0.04) presented a longer mean hospital stays. Younger patients with more admissions, longer average stay, and a lack of follow-up by the link nurse were associated with a greater number of annual consultations (p < 0.05). CONCLUSIONS: MCC require a high number of annual consultations and have long hospital stays. The creation of specialized consultations for MCC, multidisciplinary care, and the participation of the link nurse are strategies to improve the quality of care for MCC in hospitals without specific MCC units.

Clinical Relevance of RSV and SARS-CoV-2 Coinfections in Infants and Young Children.

We analyzed the frequency, clinical impact and severity of respiratory syncytial virus (RSV) and SARS-CoV-2 coinfections in a single pediatric center between March 2020 and January 2023. Compared to single RSV infections, RSV/SARS-CoV-2 coinfections were uncommon (2.1%), occurred more frequently during circulation of omicron, and were associated with increased disease severity as defined by longer hospitalization and increased need for high-flow nasal cannula.

Long COVID-19 and Insulin Autoimmune Syndrome: A Case Report.

PURPOSE: To describe a case report of a patient with symptoms associated with metabolic alterations 1 month after having COVID-19. METHODS: Laboratory tests, clinical evaluations, and body composition assessments were performed by specialists. FINDINGS: The patient presented excessive sweating, hot flashes, dizziness, blurred vision, and seizure. Laboratory tests indicated low glucose levels after convulsions (50, 42.7, and 55 mg/dL), high insulin levels (basal, 638 µIU/mL; 2-hour, >1000 µU/mL), and positivity for anti-insulin antibodies. The patient was diagnosed with insulin autoimmune syndrome. Treatment with azathioprine and nutritional recommendations improved remission. IMPLICATIONS: SARS-CoV-2 infection or vaccination might induce insulin tolerance failure.

Exposure to secondhand aerosol from electronic cigarettes at homes: A real-life study in four European countries.

Electronic cigarette (e-cigarette) use emits potentially hazardous compounds and deteriorates indoor air quality. Home is a place where e-cigarettes may frequently be used amid its increasing prohibition in public places. This study assessed the real-life scenario of bystanders' exposure to secondhand e-cigarette aerosol (SHA) at home. A one-week observational study was conducted within the TackSHS project in four countries (Greece, Italy, Spain, and the United Kingdom) in 2019 including: 1) homes of e-cigarette users living together with a non-user/non-smoker; and 2) control homes with no smokers nor e-cigarette users. Indoor airborne nicotine, PM2.5, and PM1.0 concentrations were measured as environmental markers of SHA. Biomarkers, including nicotine and its metabolites, tobacco-specific nitrosamines, propanediol, glycerol, and metals were measured in participants' saliva and urine samples. E-cigarette use characteristics, such as e-cigarette refill liquid's nicotine concentration, e-cigarette type, place of e-cigarette use at home, and frequency of ventilation, were also collected. A total of 29 e-cigarette users' homes and 21 control homes were included. The results showed that the seven-day concentrations of airborne nicotine were quantifiable in 21 (72.4 %) out of 29 e-cigarette users' homes; overall, they were quite low (geometric mean: 0.01 µg/m3; 95 % CI: 0.01-0.02 µg/m3) and were all below the limit of quantification in control homes. Seven-day concentrations of PM2.5 and PM1.0 in e-cigarette and control homes were similar. Airborne nicotine and PM concentrations did not differ according to different e-cigarette use characteristics. Non-users residing with e-cigarette users had low but significantly higher levels of cotinine, 3'-OH-cotinine and 1,2-propanediol in saliva, and cobalt in urine than non-users living in control homes. In conclusion, e-cigarette use at home created bystanders' exposure to SHA regardless of the e-cigarette use characteristics. Further studies are warranted to assess the implications of SHA exposure for smoke-free policy.

Analytical study of RUNX1-RUNXT1, PML-RARA, CBFB-MYH11, BCR-ABL1p210 , and KMT2-MLLT3 in Mexican children with acute myeloid leukemia: A multicenter study of the Mexican interinstitutional group for the identification of the causes of childhood leukemia (MIGICCL).

Background: The distribution of RUNX1-RUNXT1, PML-RARA, CBFB-MYH11, BCR-ABL1p210 , and KMT2A-MLLT3 in the pediatric population with acute myeloid leukemia (AML) in many countries of Latin America is largely unknown. Therefore, we aimed to investigate the frequency of these fusion genes in children with de novo AML from Mexico City, which has one of the highest incidence rates of acute leukemia in the world. Additionally, we explored their impact in mortality during the first year of treatment. Methods: We retrospectively analyzed the presence of RUNX1-RUNXT1, PML-RARA, CBFB-MYH11, BCR-ABL1p210 , and KMT2A-MLLT3 by RT-PCR among 77 patients (<18 years) diagnosed with de novo AML between 2019 and 2021 in nine Mexico City hospitals. Results: The overall frequency of the fusion genes was 50.7%; RUNX1-RUNXT1 (22.1%) and PML-RARA (20.8%) were the most prevalent, followed by CBFB-MYH11 (5.2%) and BCR-ABL1p210 (2.4%). KMT2A-MLLT3 was not detected. Patients with PML-RARA showed the lowest survival with high early mortality events. However, more studies are required to evaluate the impact of analyzed fusion genes on the overall survival of the Mexican child population with AML. Conclusion: The pediatric population of Mexico City with AML had frequencies of AML1-ETO, PML-RARA, CBFB-MYH11, and BCR-ABL1p210 similar to those of other populations around the world. Patients with BCR-ABL1p210 and CBFB-MYH11 were few or did not die, while those with MLL-AF9 was not detected. Although patients with PML-RARA had a low survival and a high early mortality rate, further studies are needed to determine the long-term impacts of these fusion genes on this Latino population.

Clinical Phenotype of Respiratory Syncytial Virus Bronchiolitis before and during the Coronavirus Disease 2019 Pandemic.

OBJECTIVE: The main objective of this report was to comprehensively analyze the clinical characteristics of children hospitalized with respiratory syncytial virus (RSV) infections in 2021 during the coronavirus disease 2019 (COVID-19) pandemic and to compare them with those in the five previous RSV seasons. We hypothesized that the clinical and demographic features of children hospitalized with RSV infection in 2021 were different from those hospitalized in previous respiratory seasons. STUDY DESIGN: In this retrospective observational study, children younger than 2 years hospitalized with RSV bronchiolitis from January 1, 2015, to December 31, 2021, at the Department of Pediatrics of the Hospital Gregorio Marañón, Madrid, Spain, were included. We compared the clinical characteristics of children hospitalized with RSV bronchiolitis in the five seasons before the COVID-19 pandemic and during the subsequent off-seasonal surge of RSV infections. RESULTS: We found a significant reduction in hospitalizations for RSV bronchiolitis during the usual winter epidemic period due to the COVID-19 pandemic. Children hospitalized with RSV infection in 2021, during the COVID-19 pandemic, were older than children hospitalized in the prepandemic period (2015-2020; 4.0 [1.6-9.2] vs. 3 [1.5-6.5] months; p < 0.01). We also found shorter duration of oxygen days during the COVID-19 period compared with previous respiratory seasons (3 [2-5] vs. 4 [2-6] days; p = 0.02). CONCLUSION: The COVID-19 pandemic modified the RSV seasonality with a significant reduction in RSV hospitalizations during the expected 2020-2021 season and a reappearance of RSV 7 months later than expected. We also found changes in the median age of children with RSV bronchiolitis during the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic compared with the prepandemic RSV seasons and shorter duration of oxygen days suggesting a modest reduction in disease severity. We hypothesize that this observation reflects the lack of RSV circulation in the previous months (April 2020-March 2021), with a larger pool of vulnerable infants that had not been previously infected. KEY POINTS: · The COVID-19 pandemic shifted RSV seasonality.. · RSV children hospitalized during the pandemic were older.. · Modest reduction in disease severity was observed during the pandemic..

¿Sobreestimamos las necesidades de líquidos? Complicaciones del uso de sueros isotónicos de mantenimiento en plantas de hospitalización pediátrica / Do we overestimate intravenous fluid therapy needs? Adverse effects related to isotonic solutions during paediatric hospital admissions

Introducción: La fluidoterapia intravenosa es un tratamiento ampliamente utilizado en pacientes pediátricos hospitalizados. El objetivo del estudio fue analizar las complicaciones asociadas al uso de sueros isotónicos de mantenimiento en pacientes hospitalizados y comparar la frecuencia de aparición de estas complicaciones con distintos ritmos de administración. Materiales y métodos: Se realizó un estudio observacional y prospectivo, en el que se incluyeron pacientes hospitalizados de entre tres meses y 15 años de edad que recibieron tratamiento con fluidoterapia isotónica 0,9% con glucosa al 5% durante las primeras 24 horas de ingreso. Se dividieron en dos cohortes según el ritmo de fluidoterapia: restringido<100% vs. no restringido cercano al 100% necesidades basales (NNBB), calculadas según la regla de Holliday y Segar. Se recogieron variables clínicas y analíticas en dos tiempos de estudio (T0 al ingreso y T1 a las 24 horas de la fluidoterapia). Se realizó un estudio uni y multivariante para identificar factores de riesgo de complicaciones. Resultados: Se incluyeron 84 pacientes, de los cuales 33 recibieron fluidoterapia restringida y 51 pacientes con 100% NNBB. Las principales complicaciones desarrolladas en las primeras 24 horas fueron hipercloremia> 110 mEq/L (16,6%) y edemas (19%). La aparición de edemas fue más frecuente en pacientes de menor edad (p <0,01) y la hipercloremia se asoció con el desarrollo de edemas (OR 1,73 [1,0-3,8]), p=0,06. Conclusiones: La administración de sueros isotónicos no está exenta de complicaciones, probablemente relacionadas con el ritmo de administración y más frecuentes en lactantes. Son necesarios estudios que revisen las necesidades de líquidos en niños hospitalizados. (AU)

Introduction: Maintenance intravenous fluids are frequently used in hospitalised paediatric patients. The aim of the study was to describe the adverse effects of isotonic fluid therapy in hospitalised patients, and its prevalence based on the rate of infusion. Materials and methods: A prospective clinical observational study was designed. We included hospitalised patients between 3 months-old and 15-years-old were included with 0.9% isotonic solutions with 5% glucose within the first 24h of administration. They were divided into two groups, depending on the quantity of liquid they received (restricted<100% vs. 100% maintenance needs). Clinical data and laboratory findings were recorded in two different times (T0 when they were admitted to hospital and T1 within the first 24h of administration). Results: The study included 84 patients, 33 received <100% maintenance needs and 51 patients received around 100%. The main adverse effects notified in the first 24h of administration were hyperchloremia>110mEq/L (16.6%) and oedema (19%). Oedema was more frequent in patients with lower age (p<0.01). The hyperchloremia at 24h of intravenous fluids was an independent risk factor of developing oedema (OR 1.73 [1.0–3.8], p=0.06). Conclusions: The use of isotonic fluids is not free from adverse effects, probably related to the rate of infusion and more likely to appear in infants. It is necessary more studies that review the correct estimation of intravenous fluid needs in hospitalised children. (AU)

Low Prevalence of ETV6::RUNX1 Fusion Gene in a Hispanic Population.

ETV6::RUNX1 is a genetic rearrangement of good prognosis in children with acute lymphoblastic leukemia (ALL). In Mexico, its prevalence is low in comparison with Caucasian populations. We developed a novel TaqMan one-step RT-qPCR approach to assess the prevalence of four genetic rearrangements in a cohort of Hispanic children with ALL from Mexico City. The prevalence of common fusion gene transcripts was as follows: TCF3::PBX1 7.7%; BCR::ABL1p 190 3.3%; and KMT2A::AFF1 2.8%, and ETV6::RUNX1was observed with low prevalence (10.5%) in comparison to that reported for developed countries. This is consistent with previous findings on Mexican children with ALL and similar to those reported on children from Hispanic populations. The confirmation of a low prevalence of ETV6::RUNX1 in children of a Hispanic origin represents an advancement in the description of genetic factors of ALL in these populations.

Potential Use of Chitosan-TiO2 Nanocomposites for the Electroanalytical Detection of Imidacloprid.

The detection of toxic insecticides is a major scientific and technological challenge. In this regard, imidacloprid is a neonicotinoid that is a systemic insecticide that can accumulate in agricultural products and affect human health. This work aims to study the properties of chitosan-TiO2 nanocomposites in which nanoparticles with high surface area serve as molecular recognition sites for electroanalytical imidacloprid detection. We show that the best sensitivity to imidacloprid was obtained using a modified electrode with a chitosan-TiO2 nanocomposite with a 40 wt.% of TiO2 nanoparticles. By using a three-phase effective permittivity model which includes chitosan, TiO2, an interface layer between nanoparticles and a matrix, we showed that nanocomposites with 40 wt.% of TiO2 the interface volume fraction reaches a maximum. At higher nanoparticle concentration, the sensitivity of the sensor decreases due to the decreasing of the interface volume fraction, agglomeration of nanoparticles and a decrease in their effective surface area. The methodology presented can be helpful in the design and optimization of polymer-based nanocomposites for a variety of applications.

Yeasts Inhabiting Extreme Environments and Their Biotechnological Applications.

Yeasts are microscopic fungi inhabiting all Earth environments, including those inhospitable for most life forms, considered extreme environments. According to their habitats, yeasts could be extremotolerant or extremophiles. Some are polyextremophiles, depending on their growth capacity, tolerance, and survival in the face of their habitat's physical and chemical constitution. The extreme yeasts are relevant for the industrial production of value-added compounds, such as biofuels, lipids, carotenoids, recombinant proteins, enzymes, among others. This review calls attention to the importance of yeasts inhabiting extreme environments, including metabolic and adaptive aspects to tolerate conditions of cold, heat, water availability, pH, salinity, osmolarity, UV radiation, and metal toxicity, which are relevant for biotechnological applications. We explore the habitats of extreme yeasts, highlighting key species, physiology, adaptations, and molecular identification. Finally, we summarize several findings related to the industrially-important extremophilic yeasts and describe current trends in biotechnological applications that will impact the bioeconomy.

Changes in alcohol use during the COVID-19 pandemic in Europe: A meta-analysis of observational studies.

ISSUES: Numerous studies have examined the impact of the COVID-19 pandemic on alcohol use changes in Europe, with concerns raised regarding increased use and related harms. APPROACH: We synthesised observational studies published between 1 January 2020 and 31 September 2021 on self-reported changes in alcohol use associated with COVID-19. Electronic databases were searched for studies evaluating individual data from European general and clinical populations. We identified 646 reports, of which 56 general population studies were suitable for random-effects meta-analyses of proportional differences in alcohol use changes. Variations by time, sub-region and study quality were assessed in subsequent meta-regressions. Additional 16 reports identified were summarised narratively. KEY FINDINGS: Compiling reports measuring changes in overall alcohol use, slightly more individuals indicated a decrease than an increase in their alcohol use during the pandemic [3.8%, 95% confidence interval (CI) 0.00-7.6%]. Decreases were also reported more often than increases in drinking frequency (8.0%, 95% CI 2.7-13.2%), quantity consumed (12.2%, 95% CI 8.3-16.2%) and heavy episodic drinking (17.7%, 95% CI 13.6-21.8%). Among people with pre-existing high drinking levels/alcohol use disorder, high-level drinking patterns appear to have solidified or intensified. IMPLICATIONS: Pandemic-related changes in alcohol use may be associated with pre-pandemic drinking levels. Increases among high-risk alcohol users are concerning, suggesting a need for ongoing monitoring and support from relevant health-care services. CONCLUSION: Our findings suggest that more people reduced their alcohol use in Europe than increased it since the onset of the pandemic. However high-quality studies examining specific change mechanisms at the population level are lacking.

Do we overestimate intravenous fluid therapy needs? Adverse effects related to isotonic solutions during pediatric hospital admissions.

INTRODUCTION: Maintenance intravenous fluids are frequently used in hospitalised pediatric patients. The aim of the study was to describe the adverse effects of isotonic fluid therapy in hospitalised patients, and its prevalence based on the rate of infusion. MATERIALS AND METHODS: A prospective clinical observational study was designed. We included hospitalised patients between 3 months-old and 15-years-old were included with 0,9% isotonic solutions with 5% glucose within the first 24 h of administration. They were divided into two groups, depending on the quantity of liquid they received (restricted <100% vs 100% maintenance needs). Clinical data and laboratory findings were recorded in two different times (T0 when they were admitted to hospital and T1 within the first 24 h of administration). RESULTS: The study included 84 patients, 33 received <100% maintenance needs and 51 patients received around 100%. The main adverse effects notified in the first 24 h of administration were hyperchloremia >110 mEq/L (16.6%) and oedema (19%). Oedema was more frequent in patients with lower age (p < 0,01). The hyperchloremia at 24 h of intravenous fluids was an independent risk factor of developing oedema (OR 1,73 (1,0-3,8), p = 0,06). CONCLUSION: The use of isotonic fluids is not free from adverse effects, probably related to the rate of infusion and more likely to appear in infants. It`s necessary more studies that review the correct estimation of intravenous fluid needs in hospitalized children.

Nasal and Fecal Microbiota and Immunoprofiling of Infants With and Without RSV Bronchiolitis.

Bronchiolitis associated with the respiratory syncytial virus (RSV) is the leading cause of hospitalization among infants aged < 1 year. The main objective of this work was to assess the nasal and fecal microbiota and immune profiles in infants with RSV bronchiolitis, and to compare them with those of healthy infants. For this purpose, a total of 58 infants with RSV-positive bronchiolitis and 17 healthy infants (aged < 18 months) were recruited in this case-control study, which was approved by the Ethics Committee of the Hospital Gregorio Marañón. Nasal and fecal samples were obtained and submitted to bacterial microbiota analysis by 16S rDNA sequencing and to analysis of several immune factors related to inflammatory processes. Nasal samples in which Haemophilus and/or Moraxella accounted for > 20% of the total sequences were exclusively detected among infants of the bronchiolitis group. In this group, the relative abundances of Staphylococcus and Corynebacterium were significantly lower than in nasal samples from the control group while the opposite was observed for those of Haemophilus and Mannheimia. Fecal bacterial microbiota of infants with bronchiolitis was similar to that of healthy infants. Significant differences were obtained between bronchiolitis and control groups for both the frequency of detection and concentration of BAFF/TNFSF13B and sTNF.R1 in nasal samples. The concentration of BAFF/TNFSF13B was also significantly higher in fecal samples from the bronchiolitis group. In conclusion, signatures of RSV-associated bronchiolitis have been found in this study, including dominance of Haemophilus and a high concentration of BAFF/TNFSF13B, IL-8 and sTNF.R1 in nasal samples, and a high fecal concentration of BAFF/TNFSF13B.

Genotype-Environment Interaction Analysis of NQO1, CYP2E1, and NAT2 Polymorphisms and the Risk of Childhood Acute Lymphoblastic Leukemia: A Report From the Mexican Interinstitutional Group for the Identification of the Causes of Childhood Leukemia.

Background: Acute lymphoblastic leukemia (ALL) is the main type of cancer in children. In Mexico and other Hispanic populations, the incidence of this neoplasm is one of the highest reported worldwide. Functional polymorphisms of various enzymes involved in the metabolism of xenobiotics have been associated with an increased risk of developing ALL, and the risk is different by ethnicity. The aims of the present study were to identify whether NQO1, CYP2E1, and NAT2 polymorphisms or some genotype-environmental interactions were associated with ALL risk in Mexican children. Methods: We conducted a case-control study including 478 pediatric patients diagnosed with ALL and 284 controls (children without leukemia). Ancestry composition of a subset of cases and controls was assessed using 32 ancestry informative markers. Genetic-environmental interactions for the exposure to hydrocarbons were assessed by logistic regression analysis. Results: The polymorphisms rs1801280 (OR 1.54, 95% CI 1.21-1.93), rs1799929 (OR 1.96, 95% CI 1.55-2.49), and rs1208 (OR 1.44, 95% CI 1.14-1.81) were found to increase the risk of ALL; being the risks higher under a recessive model (OR 2.20, 95% CI 1.30-1.71, OR 3.87, 95% CI 2.20-6.80, and OR 2.26, 95% CI 1.32-3.87, respectively). Gene-environment interaction analysis showed that NAT2 rs1799929 TT genotype confers high risk to ALL under exposure to fertilizers, insecticides, hydrocarbon derivatives, and parental tobacco smoking. No associations among NQO1, CYP2E1, and ALL were observed. Conclusion: Our study provides evidence for the association between NAT2 polymorphisms/gene-environment interactions, and the risk of childhood ALL in Mexican children.
