Extremely preterm infants (gestational age ≤ 28 weeks) often require EndoTracheal Tube-Invasive Mechanical Ventilation (ETT-IMV) to survive. Clinicians wean infants off ETT-IMV as early as possible using their judgment and clinical information. However, assessment of extubation readiness is not accurate since 20 to 40% of preterm infants fail extubation. We extended our work in automated prediction of extubation readiness by examining correlations of automated cardiorespiratory features to clinical parameters in successfully extubated infants. Only a few features, mainly those related to variability of breathing synchrony, had any consistent correlation with clinical parameters, namely gestational age, day of life at extubation, and bicarbonate. We conclude that the automated cardiorespiratory features likely provide different information additional to clinical practice.

Background: Pulmonary hypertension (PH) is a systemic illness with increasingly subtle disease manifestations including sleep disruption. Patients with PH are at increased risk for disturbances in circadian biology, although to date there is no data on "morningness" or "eveningness" in pulmonary vascular disease.
Research Questions: Our group studied circadian rhythms in PH patients based upon chronotype analysis, to explore whether there is a link between circadian parameters and physiologic risk-stratifying factors to inform novel treatment strategies in patients with PH?
Study Design And Methods: We serially recruited participants from July 2022 to March 2024, administering in clinic the Munich Chronotype Questionnaire (MCTQ).

Background: Gastroesophageal reflux disease has a prevalence of 12% in the Brazilian population. Its treatment includes hygienic-dietary changes, use of medications and, in selected cases, surgery with laparos-copic hiatoplasty and Nissen total fundoplication. However, this last treatment modality presents risks of postoperative dysphagia.

Background: Chronic kidney disease (CKD) is associated with a higher prevalence of valvular diseases and increased mortality from cardiovascular causes. Factors that influence the genesis of cardiac valve calcification (CVC) in these patients are not well-defined.
Objective: To determine the risk factors for valvular calcification in patients with CKD.

The aim of this in-vitro study was to verify which field of view (FOV) in cone-beam computed tomography (CBCT) yields greater accuracy in the detection of internal root resorption (IRR) volume, in comparison to the gold standard of micro-computed tomography (micro-CT) and to a physical method. Twenty-five extractedsingle-rooted teeth were scanned by CBCT with two different FOV parameters (6x6-FOV and 10x10-FOV) and via micro-CT. The volume of dental hard tissue was measured on these images.

Advancements in digital media have driven the study and use of photographic records as a diagnostic method for carious lesions, with smartphone images being widely utilized across various health fields. This study aimed to evaluate the diagnostic accuracy of smartphone photography for detecting active caries in orthodontic patients. The sample comprised 100 individuals of both sexes, aged 11 to 46 years, who were undergoing fixed orthodontic treatment.
