Introduction: Obstructive sleep apnea syndrome has multifactorial causes. Although indications for surgery are evaluated by well-known diagnostic tests in the awake state, these do not always correlate with satisfactory surgical results.
Objective: To undertake a systematic review on endoscopy during sleep, as one element of the diagnosis routine, aiming to identify upper airway obstruction sites in adult patients with OSAS.
Methods: By means of electronic databases, a systematic review was performed of studies using drug-induced sleep endoscopy to identify obstruction sites in patients with OSAS.
Results: Ten articles were selected that demonstrated the importance of identifying multilevel obstruction, especially in relation to retrolingual and laryngeal collapse in OSAS.
Conclusion: DISE is an additional method to reveal obstruction sites that have not been detected in awake patients.

Background: T/histiocyte-rich large B-cell lymphoma (T/HRBCL) is a highly aggressive subtype of diffuse large B-cell lymphoma characterized histologically by the presence of a few neoplastic large B cells amidst an abundant background of reactive T lymphocytes and/or histiocytes. T/HRBCL commonly affects the lymph nodes, followed by extranodal sites, such as the spleen, liver, and bone marrow, with rare occurrences in the gastrointestinal tract. Primary gastrointestinal T/HRBCL lacks specific clinical and endoscopic manifestations, and it is difficult to differentiate from inflammatory diseases, nodular lymphocyte predominant Hodgkin lymphoma, and other diseases on a histological basis, thereby hindering early diagnosis.

Investigating how the size of carbon support pores influences the three-phase interface of platinum (Pt) particles in fuel cells is essential for enhancing catalyst utilization. This study employed molecular dynamics simulations and density functional theory calculation to examine the effects of mesoporous carbon support size, specifically its pore diameter, on Nafion ionomer distribution, as well as on proton and gas/liquid transport channels, and the utilization of Pt active sites. The findings show that when Pt particles are located within the pores of carbon support (Pt/PC), there is a significant enhancement in the spatial distribution of Nafion ionomer, along with a reduction in encapsulation around the Pt particles, compared to when Pt particles are positioned on the surface or in excessively large pores of the carbon support.

Background: Mycobacterium avium complex (MAC) is a common pathogen causing non-tuberculous mycobacterial infections, primarily affecting the lungs. Disseminated MAC disease occurs mainly in immunocompromised individuals, such as those with acquired immunodeficiency syndrome, hematological malignancies, or those positive for anti-interferon-γ antibodies. However, its occurrence in solid organ transplant recipients is uncommon.

Purpose: Children with achondroplasia (ACH) are at risk for sudden death in infancy due to sleep disordered breathing (SDB) and foramen magnum stenosis (FMS). Sleep studies and neuroimaging are performed in infants with ACH, but interpretation of infant studies is challenging. We sought to describe baseline data on polysomnography (PSG) indices in infants with achondroplasia as well as effects of age and surgery on these parameters.
