Are Textual Recommendations Enough? Guiding Physicians Toward the Design of Machine Learning Pipelines Through a Visual Platform
The prevalence of artificial intelligence (AI) in our daily lives is often
exaggerated by the media, leading to a positive public perception while overlooking
potential problems. In the field of medicine, it is crucial to educate future healthcare
professionals on the advantages and disadvantages of AI and to emphasize
the importance of creating fair, ethical, and reproducible models. The KoopaML
platform was developed to provide an educational and user-friendly interface for
inexperienced users to create AI pipelines. This study analyzes the quantitative
and interaction data gathered from a usability test involving physicians from the
University Hospital of Salamanca, with the aim of identifying new interaction
paradigms to improve the platform’s usability. The results shown that the platform
is difficult to learn for inexperienced users due to its contents related to AI.
Following these results, a set of improvements are proposed for the next version
of KoopaML, focusing on reducing the interactions needed to create the pipelines
Flexible Heuristics for Supporting Recommendations Within an AI Platform Aimed at Non-expert Users
The use of Machine Learning (ML) to resolve complex tasks has
become popular in several contexts. While these approaches are very effective
and have many related benefits, they are still very tricky for the general audience.
In this sense, expert knowledge is crucial to apply ML algorithms properly
and to avoid potential issues. However, in some situations, it is not possible to
rely on experts to guide the development of ML pipelines. To tackle this issue,
we present an approach to provide customized heuristics and recommendations
through a graphical platform to build ML pipelines, namely KoopaML, focused
on the medical domain.With this approach, we aim not only at providing an easy
way to apply ML for non-expert users, but also at providing a learning experience
for them to understand how these methods work
Recomendaciones –guía– en la lesión aguda medular intraoperatoria en cirugía correctora del raquis
Producción CientíficaEl objetivo del tratamiento quirúrgico para la escoliosis,
cifosis y otro tipo de deformidades del raquis es
la fusión de las vértebras para que la columna vertebral
no pueda curvarse. Se colocan implantes metálicos
(barras, tornillos, alambres, placas, etc.), para
mantener el raquis mientras las vértebras se fusionan.
La artrodesis vertebral se potencia con injerto (autogénico
y/o alogénico) de hueso. El abordaje quirúrgico
puede ser posterior, anterior o combinación de ambos.
La cirugía toracoscópica se puede utilizar en el abordaje
anterior del raquis dorsal.
La cirugía correctora del raquis en pediatría y adultos
es un procedimiento prolongado (en general más de 4
horas), tiene las complicaciones potenciales de la cirugía
mayor (hemorragia grave, hipotermia, infección,
embolismo graso o aéreo, hipotensión arterial, etc.)1,2 y
entre las patrimoniales, las neurológicas (plejia, paresia)
son las más catastróficas3,

Glycemic Stress Index: Does It Correlate with the Intensive Care Length of Stay?
Postoperative hyperglycemia is an independent risk factor for postoperative complications. In adults, perioperative hyperglycemia is influenced by prolonged fasting, but data in children are lacking. The Glycemic Stress Index (GSI) has been shown to predict prolonged Pediatric Intensive Care Unit (PICU) stays in neurosurgical patients. This study aimed to confirm the correlation between GSI and duration of intubation, PICU stay, and postoperative complications in infants undergoing elective open heart surgery. The correlation between preoperative fasting and GSI was also investigated. Methods: A retrospective chart review of 85 infants ≤ 6 months undergoing elective open heart surgery was performed. GSI values ≥ 3.9 and 4.5 were tested to determine whether they carried a higher incidence of postoperative complications (metabolic uncoupling, kidney injury, ECMO, and death). The correlation between GSI and the length of intubation, PICU stay, and duration of fasting were also investigated. Perioperative factors such as age, weight, blood gas analysis, use of inotropes, and risk adjustment for congenital heart surgery were also analyzed as possible predictors. Results: GSI correlated with the duration of intubation and PICU stay. A GSI ≥ 4.5, but not 3.9, was associated with a higher incidence of metabolic uncoupling. GSI was not influenced by preoperative fasting. None of the preoperative patient factors analyzed was associated with prolonged intubation, PICU stay, or PICU complications. An abnormal creatinine before surgery increased the risk of developing acute kidney injury postoperatively. Conclusions: GSI may be valuable to predict prolonged intubation, PICU stay, and metabolic derangement in infants undergoing cardiac surgery. Fasting does not appear to affect GSI

The Pittsburgh Sleep Quality Index: Reliability, Factor Structure, and Related Clinical Factors among Children, Adolescents, and Young Adults with Chronic Pain
This study is aimed at assessing the psychometric properties and the factorial structure of the Pittsburgh Sleep Quality Index (PSQI) in a clinical sample of children, adolescents, and young adults with chronic pain. Data of 482 participants (aged 8-21 years) from two crosssectional studies and a chronic pain services outpatient clinic were analyzed. Exploratory and confirmatory factor analysis and reliability analysis of PSQI component scores were performed. Relationships between the PSQI global score and various clinical measures were investigated to assess external validity. The findings exhibit the reliability and validity of a single-factor model of the PSQI in a clinical sample of youth with chronic pain and support the relationship in this specific population between poor sleep quality and important clinical measures of well-being. These results support an informed decision regarding its use with this specific population and underscore the clinical relevance of assessing sleep quality
Transnasal Sphenopalatine Ganglion Block for the Preventive Treatment of Chronic Daily Headache in Adolescents
Chronic headaches are a major source of morbidity in the pediatric population, affecting physical function, school attendance, social capacity, mood, and sleep. In adults, repetitive sphenopalatine ganglion (SPG) blockade has been studied as a preventive treatment for chronic migraines. This case series aims to evaluate the SPG block for the preventive treatment of chronic daily headache (CDH) in adolescents. We prospectively evaluated 17 adolescents (14 females, 14 ± 1 year) with CDH not responding to cognitive behavioral therapy (CBT), physiotherapy, and standard medications. Each patient received 10 SPG blocks (two blocks/week) using the Tx360® device. At the end of treatment, 10 patients (59%) reported a Patient’s Global Impression of Change (PGIC) score ≥ 67%, and 3 months after the end of treatment, nine patients (53%) sustained a PGIC ≥ 67%. There was also a statistically significant reduction in the depression subscale of the Revised Children’s Anxiety and Depression Scale (RCADS) at the end of treatment and 3 months post-treatment compared with baseline. The procedure was well tolerated with no adverse effects. In our study, the use of repeat SPG blockade was associated with sustained benefits on the PGIC and the depression subscale of the RCADS when used as preventive headache treatment in adolescents with refractory CDH
