The role of endothelial frequency in the cerebral blood flow control during neonatal asphyxia: a retrospective longitudinal study.

BACKGROUND: Cerebral blood flow dynamics can be explored through analysis of endothelial frequencies. Our hypothesis posits a disparity in endothelial activity among neonates with perinatal asphyxia, stratified by the presence or absence of neuronal lesions. METHODS: We conducted a retrospective longitudinal study involving newborns treated with hypothermia for moderate to severe asphyxia. Participants were grouped based on the presence or absence of neuronal damage to investigate temporal endothelial involvement in cerebral blood flow regulation. Regional cerebral oxygen saturation (rScO2) was measured using near-infrared spectroscopy (NIRS), and temporal series were analyzed in the frequency domain, utilizing the original frequency of the INVOS™ device. RESULTS: The study included 88 patients, with 53% (47/88) being male and 33% (29/88) demonstrating brain lesions on magnetic resonance imaging. Among them, 86% (76/88) had a gestational age exceeding 37 weeks according to the Ballard scale, and 81% (71/88) had a birth weight exceeding 2500 g. Cohen's d effect size was calculated to assess differences in endothelial frequency between groups, indicating a small effect size based on cerebral MRI findings (Cohen's d values for Day 2 = 0.2351 and Day 3 = 0.2325). CONCLUSION: NIRS represents a valuable tool for monitoring cerebral autoregulation in neonates affected by perinatal asphyxia, underscoring the utility of assessing endothelial frequency or energy on rScO2 measured by NIRS using the original INVOS™ device frequency.

Musicoterapia en pacientes con la COVID-19

Introducción: La musicoterapia puede ser utilizada para influenciar en el estado físico y emocional de pacientes diagnosticados con la COVID-19. Se realiza una revisión sistemática exploratoria que incluye estudios observacionales y ensayos clínicos; Pubmed y Scopus fueron las bases de datos empleadas para la realización de la búsqueda. Además, se incluyen registros de ensayos clínicos de la Plataforma de Registros Internacionales de Ensayos Clínicos de la Organización Mundial de la Salud. Objetivo: Explorar la literatura médica disponible, sobre el impacto clínico de la musicoterapia en pacientes diagnosticados con la COVID-19. Desarrollo: De 39 documentos encontrados se incluyen 2 artículos: un ensayo clínico y un reporte de caso, con una población total de 41 pacientes. Se encuentra evidencia médica que respalda el impacto clínico favorable sobre la saturación de oxígeno, rehabilitación física y síntomas asociados al estrés en pacientes con diagnóstico de la COVID-19 con y sin requerimiento de soporte ventilatorio. Conclusiones: La musicoterapia es una herramienta útil en el tratamiento y rehabilitación no farmacológica de pacientes con la COVID-19; sin embargo, son necesarios nuevos estudios clínicos con mayor número de poblaciones muestrales y mayor tiempo de seguimiento.

Background: Music therapy can be used to influence the physical and emotional state of patients diagnosed with COVID-19. An exploratory systematic review was carried out including observational studies and clinical trials, Pubmed and Scopus were the databases used to carry out the literature search. In addition, clinical trial registries from the World Health Organization International Clinical Trials Registry Platform are included. Objective: To explore the available medical literature on the clinical impact of music therapy in patients diagnosed with COVID-19. Development: Of 39 documents found in the search, two articles are included: a clinical trial and a case report, with a total population of 41 patients. Medical evidence is found to support the favorable clinical impact on oxygen saturation, physical rehabilitation and symptoms associated with stress in patients diagnosed with COVID-19 with and without the need for ventilatory support. Conclusions: Music therapy is a useful tool in the non-pharmacological treatment and rehabilitation of patients with COVID-19. However, new clinical studies with a larger number of sample populations and follow-up times using music therapy in this disease are necessary.
