Introduction: According to the prefrontal model, individuals with obstructive sleep apnea (OSA) manifest behaviours mimicking dysexecutive syndrome as a result of blood gas abnormalities and sleep fragmentation.
Objective: To compare executive functions in OSA patients with normative values and explore their relationship with blood gas abnormalities and sleep fragmentation.
Patients And Methods: Patients were recruited from the wider community and from a tertiary care hospital. The score obtained in the neuropsychological assessment was compared with Student's t-test for a sample. A multiple linear regression analysis was subsequently estimated, using polysomnographic parameters of hypercapnia, hypoxemia and sleep fragmentation as the predictor variables, and the executive function score as the variable to be predicted.
Results: Although the neuropsychological assessment performance of 26% of this sample was classified as executive impairment, indicators of sleep fragmentation and gas abnormalities failed to predict the performance of executive functions.
Conclusion: A proportion of the patients with OSA presented performance similar to a dysexecutive syndrome; however, the factors underlying and fostering this type of cognitive manifestation remain unclear. Early treatment for this public health problem could be the best tool available for improving quality of life and preventing health risks.

As a necessary part of intelligent control of a joint station, the automatic identification of abnormal conditions and automatic adjustment of operation schemes need to judge the running state of the system. In this paper, a combination of Particle Swarm Optimization (PSO) and Gray Wolf Optimizer (GWO) is proposed to optimize the Backpropagation Neural Network (BP) model (PSO-GWO-BP) and a pressure drop prediction model for the joint station export system is established using PSO-GWO-BP. Compared with the traditional hydraulic calculation modified (THCM) models and other machine learning algorithms, the PSO-GWO-BP model has significant advantages in prediction accuracy.

Pulmonary sequestration (PS) is a rare congenital malformation that is characterized by the absence of a connection between a portion of the lung tissue and the tracheobronchial tree, with blood supply from arteries throughout the body. Abnormal lung tissue cannot perform the normal gas exchange function. In the absence of timely diagnosis and early intervention, some cases may need labor induction, and some of the infants who survive may develop symptoms in childhood.

Aims: Left ventricular (LV) diastolic dysfunction and heart failure with preserved ejection fraction (HFpEF) are common cardiac complications of patients with systemic sclerosis (SSc). Exercise stress echocardiography is often used in symptomatic patients with SSc to detect abnormal increases in pulmonary pressures during exercise, but the pathophysiologic and prognostic significance of exercise stress echocardiography to assess the presence of HFpEF in these patients is unclear.
Methods And Results: Patients with SSc (n=140) underwent ergometry exercise stress echocardiography with simultaneous expired gas analysis.

Cystic cuboid adenomatous malformations (CCAM) are congenital pulmonary lesions, usually benign, that can progress into malignancy. Bronchopulmonary sequestration (BPS) is another type of malformation that consistsof an ectopic pulmonary tissue mass that doesn't participate in blood-gas exchanges, with vascularization provided by anomalous branches of the thoracic aorta. Hybrid lesions are lesions that have histological features of CCAM but with systemic vascularization, a pathognomonic sign of BPS.

The abnormal alternation of pulmonary angiogenesis is related to lung microvascular dysfunction and is deeply linked to vascular wall integrity, blood flow regulation, and gas exchange. In murine models, lung lobes exhibit significant differences in size, shape, location, and vascularization, yet existing methods lack consideration for these variations when quantifying microvascular density. This limitation hinders the comprehensive study of lung microvascular dysfunction and the potential remodeling of microvasculature circulation across different lobules.
