Secondary pseudohypoaldosteronism: a 15-year experience and a literature review.

BACKGROUND: Secondary pseudohypoaldosteronism (S-PHA) is a rare condition resulting from renal tubular resistance to aldosterone in children with urinary tract infection (UTI) and/or nephrourological malformations. It is characterized by nonspecific symptoms but with the potential for life-threatening complications. We aim to evaluate the clinical manifestations, diagnostic approach, and therapeutic interventions in children with S-PHA, along with a review of recent publications. METHODS: A retrospective observational descriptive study was conducted on S-PHA cases diagnosed over the last 15 years at a tertiary pediatric nephrology unit. The literature for the last 10 years was reviewed. RESULTS: Twelve patients (10 males, 6 days to 6 months) were identified. Weight loss was the main reason for consultation (50%). Ninety-two percent of patients had an underlying nephrourological pathology and 62% concomitant confirmed UTI. Seven out of 12 children were admitted to the PICU. A subsequent extrapontine myelinolysis was observed in one patient as neurological sequelae. Twenty-one articles related to S-PHA have been identified on PubMed and Embase. CONCLUSIONS: S-PHA should be considered in infants under 6 months of age with UTI and/or CAKUT. Obstructive anomalies and vesicoureteral reflux can be found, affecting both unilateral and bilateral systems. Early medical and surgical interventions are crucial and require close monitoring to avoid iatrogenic complications.

Hospital-based screening outperforms primary care screening as a means of achieving hepatitis C virus micro-elimination.

AIM: To assess the respective performances of a HCV screening program in a hospital setting and a HCV screening model applied concomitantly in a primary care centre. METHODS: Adult patients consecutively admitted to hospital for ambulatory surgery were screened for anti-HCV antibodies (hospital screening cohort, HPSC), as were patients receiving blood tests for medical reasons in a primary care centre (primary care screening cohort, PCSC). Serum anti-HCV and HCV RNA levels were tested by ELISA and real-time PCR, respectively. RESULTS: Seroprevalence of HCV infection was 2.2 % in the HPSC and 1.4 % in the PCSC (p = 0.044). All viraemic patients (0.2 % in HPSC and 0.1 % in PCSC) were treated with direct-acting antivirals and 85.7 % experienced a sustained virological response. CONCLUSIONS: Hospital-based HCV screening outperformed primary care-centered screening, significantly increasing HCV case findings.

Alcohol Use Patterns Among Underage Autistic and Non-Autistic Youth.

PURPOSE: We explored factors predicting repeated or hazardous alcohol use among autistic and non-autistic U.S. youth ages 16 to 20 years. METHODS: Autistic (n = 94) and non-autistic (n = 92) youth completed an online survey. By design, half of each group reported past-year alcohol use. We compared drinking patterns for autistic and non-autistic youth, and within each group between abstinent or infrequent drinkers (0-1 drinking episodes in past year) versus those who drank 2 + times in past year. RESULTS: Autistic (vs. non-autistic) youth who drank did so less frequently and consumed fewer drinks per occasion. However, 15% of autistic youth who drank in the past year reported heavy episodic drinking and 9.3% screened positive for AUDIT-C hazardous drinking. For autistic youth only, a diagnosis of depression, bullying or exclusion histories were positively associated with drinking 2 + times in the past year. Autistic youth who put more effort into masking autistic traits were less likely to report drinking 2 + times in the past year. As compared to non-autistic youth, autistic participants were less likely to drink for social reasons, to conform, or to enhance experiences, but drank to cope at similar rates. CONCLUSION: Repeated and hazardous underage alcohol occur among autistic youth. Targeted prevention programs designed to address the specific drinking profiles of autistic youth are needed.

An Analysis of Running Impact on Different Surfaces for Injury Prevention.

The impact that occurs on the runner's foot when it lands on the ground depends on numerous factors: footwear, running technique, foot strike and landing pattern, among others. However, the surface is a decisive factor that can be selected by the runner to improve their sports practice, thereby avoiding injuries. This study aimed to assess the number and magnitude of accelerations in impact (produced by the runner when their foot strikes the ground) on three different surfaces (grass, synthetic track, and concrete) in order to know how to prevent injuries. Thirty amateur runners (age 22.6 ± 2.43 years) participated in the study. They had to run consecutively on three different surfaces at the same speed, with a three axis-accelerometer placed on the sacrum and wearing their own shoes. The results showed that the running impacts differed based on the type of surface. Higher mean acceleration (MA) and mean peak acceleration (PA) in the impacts were observed on concrete compared to the other two surfaces. There were small differences for MA: 1.35 ± 0.1 g (concrete) vs. 1.30 ± 0.1 g (synthetic track) SD: 0.43 (0.33, 0.54) and 1.30 ± 0.1 g (grass) SD: 0.36 (0.25, 0.46), and small differences for PA: 3.90 ± 0.55 g (concrete) vs. 3.68 ± 0.45 g (synthetic track) SD 0.42 (0.21, 0.64) and 3.76 ± 0.48 g (grass) SD 0.27 (0.05, 0.48), implying that greater impacts were produced on concrete compared to synthetic track and grass. The number of peaks of 4 to 5 g of total acceleration was greater for concrete, showing small differences from synthetic track: SD 0.23 (-0.45, 0.9). Additionally, the number of steps was higher on synthetic track (34.90 ± 2.67), and small differences were shown compared with concrete (33.37 ± 2.95) SD 0.30 (-0.25, 0.85) and with grass (35.60 ± 3.94) SD 0.36 (-0.19, 0.91). These results may indicate a change in technique based on the terrain. Given the increasing popularity of running, participants must be trained to withstand the accelerations in impact that occur on different surfaces in order to prevent injuries.

AL Amyloidosis and Multiple Myeloma: A Complex Scenario in Which Cardiac Involvement Remains the Key Prognostic Factor.

Monoclonal gammopathies (MGs) are a wide range of diseases that may evolve or progress over time. Comorbidity plays a critical role in this setting. The co-occurrence of two MGs is not a rare event. The evidence on the association of systemic light chain (AL) amyloidosis and multiple myeloma (MM) is scarce and controversial. Herein we aim to address this topic in a large series of patients of a referral center. All consecutive AL amyloidosis patients treated at our center from January 2005 to April 2023 were prospectively enrolled in a clinical and epidemiological registry. 141 patients diagnosed with AL amyloidosis were included, of which 7 (5%) had localized whereas 134 presented with systemic disease. The heart was the most frequently affected organ (90.3%). 25 patients (18.7%) fulfilled the IMWG diagnostic criteria of MM (AL/MM). Time-dependent association between AL and MM showed that the synchronous pattern is more frequent than the appearance of a second primary malignancy. The diagnostic delay was six months (m). Patients with AL/MM had a poorer median overall survival (OS) than AL-only patients (35.5 m, CI 95% 0-88.9, vs. 52.6 m, CI 95% 16.7-88.5), but this difference was not statistically significant. The prognosis in AL is dominated by the heart involvement, which is massive in this series. In our Cox regression model, only three prognostic variables remain as independent prognostic factors: age, N-terminal pro-brain natriuretic peptide (≥8500 ng/L), and undergoing an autologous stem cell transplant, whereas left ventricular ejection fraction shows a marginal effect. More and large studies focusing on the AL/MM association are needed to uncover the characteristics and prognostic impact of this association.

Takayasu's arteritis as an incidental finding in a patient with celiac disease: the importance of positron emission computed tomography.

BACKGROUND: Takayasu arteritis is a large-vessel vasculitis which affects large-caliber elastic arteries, primarily the aorta and its main branches. It mainly affects women between 20-30 years, so it is rare in children. CASE REPORT: We describe the case of a 15-year-old female who was followed up since she was 9 years old due to celiac disease. At the age of 13, anaemia of chronic disorders associated to elevated C-reactive protein and erythrocyte sedimentation were detected. The patient remained asymptomatic. After excluding other diseases, we requested a positron emission computed tomography (PET-CT); lesions compatible with large-vessel vasculitis were detected. Cardiology evaluation showed an aneurysm in the right coronary artery. Angio-CT suggested Takayasu type III arteritis. CONCLUSIONS: The delay in the diagnosis of Takayasu arteritis in pediatric patients is quite common. In this case, we have found phase II lesions, with no previous phase I symptoms. However, PET-CT allowed the diagnosis of vasculitis, key to the diagnosis of the patient.

INTRODUCCIÓN: La arteritis de Takayasu es una vasculitis de grandes vasos que afecta a las arterias elásticas de gran calibre, fundamentalmente la aorta y sus ramas principales. Ocurre frecuentemente en mujeres entre los 20-30 años, por lo que es muy infrecuente en la edad pediátrica. CASO CLÍNICO: Se presenta el caso de una paciente de 15 años en seguimiento desde los 9 años por enfermedad celiaca. A los 13 años se detectó anemia de trastornos crónicos, elevación de proteína C reactiva y velocidad de sedimentación globular. La paciente permaneció en todo momento asintomática. Tras descartar otros procesos, se solicitó tomografía computarizada por emisión de positrones (PET-TC), donde se detectaron lesiones compatibles con vasculitis de grandes vasos. La valoración por Cardiología evidenció un aneurisma en coronaria derecha. Se realizó angio-TC, que sugirió arteritis de Takayasu tipo III. CONCLUSIONES: Es frecuente un retraso en el diagnóstico de la arteritis de Takayasu en los pacientes pediátricos. En este caso se encontraron lesiones de la fase II sin la presencia de síntomas correspondientes a la fase I. El PET-TC permitió el diagnóstico de vasculitis, clave para el diagnóstico de la paciente.

[Intracranial hypotension syndrome in a pediatric patient with Marfan syndrome].

Intracranial hypotension syndrome (IHS) is attributed to reduced cerebrospinal fluid (CSF) pressure. It may be spontaneous or secondary to a history of trauma or systemic disease. We present the case of an 11-year-old boy, with medical history of Marfan syndrome, with orthostatic headache and persistent vomiting (12 hours) following a fall on the sacrococcygeal region. Magnetic resonance showed extradural fluid collections at dorsal and lumbosacral levels, compatible with CSF leak. The condition was resolved with treatment, but the patient had two new episodes during the follow-up period. Thus, an epidural blood patch was performed two years after the first episode. Although HIS is uncommon in children, it should be suspected in patients with orthostatic headache, particularly if the patient presents a connectivopathy. Few studies have assessed the management of HIS in paediatric age. The case presented here and the reviewed available literature provides further data for these type of cases.

Reductions in Depression and Anxiety Among Autistic Adults Participating in an Intervention to Promote Healthy Relationships.

IMPORTANCE: Some autistic adults experience depression and anxiety related to their social relationships. There is a need for evidence-based occupational therapy interventions that decrease depression and anxiety and improve the health of social relationships for autistic adults. OBJECTIVE: To determine the feasibility and preliminary effectiveness of the Healthy Relationships on the Autism Spectrum (HEARTS) intervention, a six-session, group-based psychoeducational intervention for the improvement of relationship health. DESIGN: One-group pretest-posttest design with a 3-mo follow-up after baseline. SETTING: United States; online intervention through community organization. PARTICIPANTS: Fifty-five adults, ages 20 to 43 yr, with a professional or self-diagnosis of autism and the capacity to independently participate in an online, group-based, participatory class. INTERVENTION: Participants received 6 90-min weekly sessions that addressed healthy relationship topics, including recognizing abuse, meeting people, maintaining relationships, setting interpersonal boundaries, neurohealth for relationships, and ending relationships. A psychoeducational approach that provided education and involved guided discovery and strategy acquisition was used. OUTCOMES AND MEASURES: All measures were self-administered through an online survey. Depression and anxiety were assessed using instruments from the Patient-Reported Outcomes Measurement Information System. RESULTS: Fifty-five participants completed the intervention. Postintervention scores revealed statistically significant improvements in depression and anxiety. CONCLUSIONS AND RELEVANCE: HEARTS is a promising intervention for improving depression and anxiety among autistic adults and should be investigated further. What This Article Adds: HEARTS offers a potentially effective, nonpharmacological, psychoeducational group-based intervention option to promote healthy relationships for autistic adults. Positionality Statement: This article uses identity-first language (autistic person) in accordance with the preference of autistic self-advocates (Autistic Self Advocacy Network, 2020; Kenny et al., 2016; Lord et al., 2022).

Síndrome de hipotensión intracraneal en paciente pediátrico con síndrome de Marfan / Intracranial hypotension syndrome in a pediatric patient with Marfan syndrome

El síndrome de hipotensión intracraneal (SHI) es consecuencia del descenso de la presión de líquido cefalorraquídeo (LCR), espontáneo o secundario a antecedente traumático o enfermedad sistémica.Presentamos el caso de un niño de 11 años con cefalea ortostática y vómitos de 12 horas de evolución tras una caída sobre región sacrocoxígea; antecedente de síndrome de Marfan. La resonancia craneomedular mostró colecciones líquidas extradurales a nivel dorsal y lumbosacro compatibles con fístula de LCR. El cuadro se resolvió tras tratamiento, pero hubo dos nuevos episodios durante el seguimiento, por lo que se aplicó un parche hemático epidural a los dos años del inicio.Aunque el SHI es infrecuente en niños, debe sospecharse ante pacientes con cefalea ortostática, especialmente si existe patología favorecedora como enfermedades del tejido conectivo. Existe poca evidencia sobre el manejo en edad pediátrica, por lo que se presenta este caso y se realiza una revisión de la literatura.(AU)

How Does Instability Affect Bench Press Performance? Acute Effect Analysis with Different Loads in Trained and Untrained Populations.

(I) The execution of different sports involves a significant number of throws, jumps, or direction changes, so the body must be as stable as possible while performing a specific action. However, there is no classification of unstable devices and their influence on performance variables. Furthermore, the effect on athletes' experience using instability is unknown. (II) The aim of this study was to analyze the power and speed parameters in bench press with different loads and unstable executions: (1) stable (SB), (2) with asymmetric load (AB), (3) with unstable load (UB), (4) on fitball (FB) and (5) on a Bosu® (BB). A total of 30 male participants (15 trained and 15 untrained) were evaluated for mean propulsive speed (MPS), maximum speed (MS), and power (PW) with different types of external load: a low load (40% of 1RM), medium load (60% of 1RM), and high load (80% of 1RM) in each condition. Variables were measured with an inertial dynamometer. (III) The best data were evidenced with SB, followed by AB (3-12%), UB (4-11%), FB (7-19%), and BB (14-23%). There were no differences between groups and loads (p > 0.05) except in the case of MS with 60% 1RM, where trained participants obtained 4% better data (p < 0.05). (IV) Executions with implements and equipment such as fitball and Bosu® do not seem to be the most recommended when the objective is to improve power or execution speed. However, situations where the load is unstable (AB and UB) seem to be a good alternative to improve stabilization work without high performance. Furthermore, experience does not seem to be a determining factor.

Memory-aware curriculum federated learning for breast cancer classification.

BACKGROUND AND OBJECTIVE: For early breast cancer detection, regular screening with mammography imaging is recommended. Routine examinations result in datasets with a predominant amount of negative samples. The limited representativeness of positive cases can be problematic for learning Computer-Aided Diagnosis (CAD) systems. Collecting data from multiple institutions is a potential solution to mitigate this problem. Recently, federated learning has emerged as an effective tool for collaborative learning. In this setting, local models perform computation on their private data to update the global model. The order and the frequency of local updates influence the final global model. In the context of federated adversarial learning to improve multi-site breast cancer classification, we investigate the role of the order in which samples are locally presented to the optimizers. METHODS: We define a novel memory-aware curriculum learning method for the federated setting. We aim to improve the consistency of the local models penalizing inconsistent predictions, i.e., forgotten samples. Our curriculum controls the order of the training samples prioritizing those that are forgotten after the deployment of the global model. Our approach is combined with unsupervised domain adaptation to deal with domain shift while preserving data privacy. RESULTS: Two classification metrics: area under the receiver operating characteristic curve (ROC-AUC) and area under the curve for the precision-recall curve (PR-AUC) are used to evaluate the performance of the proposed method. Our method is evaluated with three clinical datasets from different vendors. An ablation study showed the improvement of each component of our method. The AUC and PR-AUC are improved on average by 5% and 6%, respectively, compared to the conventional federated setting. CONCLUSIONS: We demonstrated the benefits of curriculum learning for the first time in a federated setting. Our results verified the effectiveness of the memory-aware curriculum federated learning for the multi-site breast cancer classification.

Fairer Sex: The Role of Relationship Equity in Female Sexual Desire.

Previous investigations into Female Sexual Desire (FSD) have been focused on women's biological, cognitive, and emotional processes, despite evidence that FSD is also responsive to relational contexts. Past research consistently demonstrates a general association between relationship satisfaction and FSD. There remains, however, a need to expound this connection. In response, this study explored the role of relationship equity in relationship satisfaction and FSD. For this cross-sectional study, 299 Australian women aged 18 to 39 years responded to an online questionnaire measuring relationship factors and dimensions of sexual desire. Two mediation models were tested to examine how relationship equity was associated with solitary and dyadic sexual desire, via a connection with relationship satisfaction. As expected, equality in relationships predicted relationship satisfaction, which, subsequently, was related to higher levels of dyadic sexual desire. No significant mediation was found for solitary desire, indicating that relationship factors may not play a critical role in this domain. This result also demonstrates a distinct divergence between the two domains of desire that requires further examination. These results solidify the notion of FSD as a multifaceted construct and present meaningful implications for theory, research, and clinical practice.

Arteritis de Takayasu como hallazgo incidental en un paciente con enfermedad celiaca: la importancia de la tomografía computarizada por emisión de positrones / Takayasu's arteritis as an incidental finding in a patient with celiac disease: the importance of positron emission computed tomography

Estudio retrospectivo sobre la efectividad y seguridad de la pauta antibiótica reducida a 5-7 días en la faringoamigdalitis aguda estreptocócica comparada con la pauta clásica de 10 días / Retrospective study on the effectiveness and safety of the shortened 5- to 7-day antibiotic regimen for acute streptococcal pharyngotonsillitis compared to the classic 10-day regimen

Introducción: El tratamiento antibiótico clásico de la faringoamigdalitis aguda estreptocócica es una pauta de 10 días; sin embargo, la aparición de resistencias antibióticas induce a explorar pautas más cortas. Material y métodos: Seleccionamos a aquellos pacientes diagnosticados de faringoamigdalitis aguda estreptocócica en 2 cupos de pediatría de un centro de salud entre junio de 2016 y abril de 2020. Se compararon los resultados de aquellos que recibieron tratamiento 8-10 días con el de aquellos que lo recibieron 5-7 días. Resultados: Se analizaron 350 episodios (252 pacientes). El 64% recibieron tratamiento durante 8-10 días (grupo 1) y el 36% durante 5-7 días (grupo 2). No se observaron diferencias significativas en la aparición de faringoamigdalitis aguda estreptocócica o escarlatina los 3 meses posteriores (OR 0,97; IC 95%: 0,46-2,03), con una proporción similar en ambos grupos (9,8 vs. 9,5%). Sin diferenciar el tipo de infección (faringoamigdalitis aguda estreptocócica, escarlatina u otro tipo de infección streptocócica), se observaron resultados similares (OR 0,81; IC 95%: 0,41-1,59) con el 13,4% en el grupo 1 y el 11,1% en el 2. Respecto a la aparición de reacciones adversas medicamentosas recogidas en la historia clínica, fue de 2,7% en el grupo 1 y 0,8% en el 2 (OR 0,29; IC 95%: 0,04-2,44). Conclusiones: Según nuestra experiencia, la pauta antibiótica corta (5-7 días) en faringoamigdalitis aguda estreptocócica no es menos efectiva ni más insegura que la clásica pauta de 10 días. (AU)

Introduction: Antibiotherapy regimens for management of acute streptococcal pharyngitis traditionally last 10 days, but the development of resistance to different antimicrobials has motivated the exploration of shorter courses. Material and methods: We selected patients given a diagnosis of streptococcal pharyngitis in 2 paediatric caseloads of one primary care centre between June 2016 and April 2020. We compared outcomes in patients treated with 8- to 10-day courses versus 5- to 7-day courses. Results: The analysis included 350 care episodes (252 patients). Sixty-four percent were managed with 8- to 10-day courses of antibiotherapy (group 1) and 36% with 5- to 7-day courses (group 2). There were no significant differences in the incidence of streptococcal pharyngitis or scarlet fever in the 3 months that followed (OR, 0.98; 95% CI: 0.46-2.03), with similar percentages in both groups (9.8 vs. 9.5%). Overall, without differentiating based on the type of infection (streptococcal pharyngitis, scarlet fever or other streptococcal infections), we found similar outcomes (OR, 0.81; 95% CI: 0.41-1.59): 13.4% in group 1 and 11.1% in group 2. We also found no differences in the frequency of adverse events documented in the health records (OR, 0.29; 95% CI: 0.04-2.44): 2.7% in group 1 and 0.8% in group 2. Conclusions: In our experience, a shorter antibiotic course (5-7 days) is not less effective or more unsafe for management of acute streptococcal pharyngitis than the traditional 10-day course. (AU)

Miositis por SARS-CoV-2 / SARS-CoV-2-associated myositis

Se describe el caso de una paciente de 9 años que presenta, durante el seguimiento por infección por SARS-CoV-2, incapacidad para la deambulación por dolor de extremidades inferiores. Ante una clínica y exploración compatible con miositis, se realiza analítica sanguínea en la que se observa una elevación de creatinfosfoquinasa (CPK). La paciente presenta buena evolución con tratamiento sintomático. A propósito del caso se realiza una revisión bibliográfica de los casos pediátricos de miositis asociados a la infección por SARS-CoV-2 (AU)

We describe the case of a 9-year-old patient who presented with inability to walk due to lower extremity pain in the follow-up of infection by SARS-CoV-2. Since the manifestations and findings of the examination were compatible with myositis, a blood test was performed that evinced elevation of creatine phosphokinase. The patient had a favourable outcome with symptomatic treatment. In the context of this case, we conducted a literature review of paediatric cases of myositis associated with SARS-CoV-2 infection.

[Allan-Herndon-Dudley syndrome: a diagnosis to rule out in any male infant with undiagnosed hypotonia]. / Síndrome de Allan-Herndon-Dudley: un diagnóstico a descartar ante todo lactante varón con hipotonía sin causa determinada.

Allan-Herndon-Dudley syndrome is a rare X-linked genetic disorder, caused by a deficiency of the monocarboxylate transporter 8 (MCT8), a specific transporter of thyroid hormones, with functions mainly at the brain level. The syndrome produces an early onset of severe neurological disorder, in which hypotonia predominates. OBJECTIVE: To present a rare case with an unexpected diagnosis, highlighting the usefulness of requesting a complete thyroid profile in every hypotonic male infant without a specific cause. CLINICAL CASE: A 10-month-old male infant with severe axial and peripheral hypotonia, global weakness with little spontaneous mobility, without head support or stable sitting. Complete metabolic and peripheral neurophysiological studies were performed. Genetic studies for spinal muscular atrophy, Prader Willi syndrome, and myotonic dystrophy were also performed. The trio exome analysis detected a probably pathogenic variant c.359C>T;p.(Ser120Phe), hemizygous in exon 1 of the SLC16A2 gene, inherited from the mother. Thyroid abnormalities as increased free triiodothyronine (T3) and thyroid-stimulating hormone (TSH), and delayed myelination were ob served. CONCLUSIONS: MCT8 deficiency should be considered in the case of the male infant with unex plained hypotonia and weakness without a determined cause. The diagnosis is guided by a thyroid profile including free T3 hormone, because it presents a characteristic thyroid profile with decreased free thyroxine (T4), increased free T3, and normal or slightly elevated TSH levels. In this case, the implementation of the trio exome analysis allows establishing an early certain diagnosis.

Healthy Relationships on the Autism Spectrum (HEARTS): A feasibility test of an online class co-designed and co-taught with autistic people.

LAY ABSTRACT: The Healthy Relationships on the Autism Spectrum class is unique because autistic people helped to develop it and co-taught it. It is an online, six-session class. The class was piloted in 2020-2021 with 55 autistic people who were ages 18-44 years old. This feasibility study found that most people who took the class liked it. Surveys filled out by the students before and after the class showed that they became less sensitive to rejection, used more positive thinking skills, and were more interested in being social. However, the class may not have made them feel less lonely. The team that invented the class is using the feedback to improve it. The class holds promise for improving the quality of friendships and dating relationships for autistic adults and should be tested further.

Early Enteral Nutrition and Gastrointestinal Complications in Pediatric Patients on Extracorporeal Membrane Oxygenation.

OBJECTIVES: To assess the safety of enteral nutrition (EN) in children on extracorporeal membrane oxygenation (ECMO). To describe nutritional status and the characteristics of the nutritional support in this population. METHODS: A retrospective single-center analysis (2006-2016) including children <18 years on ECMO. Demographic data, nutritional status, characteristics of nutritional support, and development of gastrointestinal (GI) complications were recorded. RESULTS: One hundred children, with a median age of 9.7 months (interquartile range [IQR] 3.9-63.1) were enrolled. Undernutrition was prevalent among children on ECMO (33.3%) mainly in patients <2 years (P = 0.042). Most patients (64%) received EN at some point during ECMO therapy. EN was administered in the first 48 hours after ECMO initiation (48HEN) to 60.3% of the children.Mortality rate in the Pediatric Intensive Care Unit was lower in patients who received EN as the initial artificial nutrition support (ANS) (37.7 vs 51%, P = 0.005) and in children on 48HEN (34% vs 50%, P = 0.04). In the logistic regression analysis, duration of ECMO support and low cardiac output indication were the only factors associated with mortality.Although most patients on ECMO (45%) developed digestive complications, they were mostly mild, being constipation the most prevalent. In the logistic regression analysis, EN was not associated with an increase in GI complications (P = 0.09). Only three patients developed intestinal ischemia (one without EN and two on EN). CONCLUSIONS: Undernutrition is prevalent among children on ECMO, mainly in infants <2 years. EN is not associated with severe gastrointestinal complications or higher mortality in these children.

Curriculum learning for improved femur fracture classification: Scheduling data with prior knowledge and uncertainty.

An adequate classification of proximal femur fractures from X-ray images is crucial for the treatment choice and the patients' clinical outcome. We rely on the commonly used AO system, which describes a hierarchical knowledge tree classifying the images into types and subtypes according to the fracture's location and complexity. In this paper, we propose a method for the automatic classification of proximal femur fractures into 3 and 7 AO classes based on a Convolutional Neural Network (CNN). As it is known, CNNs need large and representative datasets with reliable labels, which are hard to collect for the application at hand. In this paper, we design a curriculum learning (CL) approach that improves over the basic CNNs performance under such conditions. Our novel formulation reunites three curriculum strategies: individually weighting training samples, reordering the training set, and sampling subsets of data. The core of these strategies is a scoring function ranking the training samples. We define two novel scoring functions: one from domain-specific prior knowledge and an original self-paced uncertainty score. We perform experiments on a clinical dataset of proximal femur radiographs. The curriculum improves proximal femur fracture classification up to the performance of experienced trauma surgeons. The best curriculum method reorders the training set based on prior knowledge resulting into a classification improvement of 15%. Using the publicly available MNIST dataset, we further discuss and demonstrate the benefits of our unified CL formulation for three controlled and challenging digit recognition scenarios: with limited amounts of data, under class-imbalance, and in the presence of label noise.
