This study aimed to determine whether new ResMed devices have a more favorable impact on CPAP therapy than previous models. Methods This prospective multicenter study was conducted at Kyoto University Hospital, Rakuwakai Otowa Hospital, Shibata Clinic, and Hatta Medical Clinic. Patients with sleep apnea syndrome who used the previous generation of ResMed devices and switched to new ResMed devices from April 2023 to June 2024 were eligible to participate in the study. CPAP device data for one month before and after switching to new ResMed devices were downloaded using ResScan, NemLink, or f'Rens. Results A total of 102 patients were included in this analysis. The switch from old to new ResMed devices resulted in significant decreases in median CPAP pressure and 95th percentile leak from 8.1 (6.8-9.9) cmH<sub>2</sub>O to 7.4 (6.2-8.8) cmH<sub>2</sub>O (p<0.0001) and from 25.2 (14.4-36.2) L/min to 21.9 (14.4-33.8) L/min (p=0.0034), respectively. The percentage of CPAP therapy used for at least 4 h increased from 86% (56.1%-94.3%) to 90% (60-100%) (p=0.0043).

This study aimed to examine whether the presence or absence of other household cohabitants, apart from spouses, affects the treatment decisions of patients with PC. Methods and Patients A retrospective analysis of patients diagnosed with PC at the Akita University Hospital between January 2014 and December 2020 was conducted. Information about the patients' backgrounds, including the number of persons residing in their households, was gathered. A multivariate regression analysis was conducted to ascertain the factors associated with patients' decisions to undergo aggressive treatment, such as surgery, chemotherapy, and radiotherapy. Results A total of 214 patients with histopathologically confirmed PC were enrolled in this study. Those who lived with others were more likely to receive aggressive treatment than those who lived alone (84.9% vs. 54.5%; p<0.01). The multivariate analysis, adjusted for patients' age, performance status, and marital status indicated that the patient's decision to undergo aggressive treatment was found to be positively associated with living with other household members with an odds ratio (95% confidence interval): 4.5 (1.02-19.9), p<0.05.

Methods We conducted a single-center retrospective study, classifying the patients into localized OMAAV and systemic OMAAV groups, based on the OMAAV diagnostic criteria, and compared their clinical features, laboratory findings, clinical course, treatment, and hearing prognosis. We also assessed any tympanic membrane findings suggestive of vasculitis using the scoring system of the OMAAV tympanic membrane (SCOT). Results We collected data from 20 OMAAV patients between January 2013 and July 2023. Seventy percent of the patients visited the otolaryngology department as their first consultation, with a median period of 2.5 months from the onset of ear symptoms to diagnosis. Compared to systemic OMAAV, localized OMAAV had fewer systemic symptoms, such as high fever, and the markers of inflammation were also lower. The positivity rate of ANCA was similar between the groups, and 90% of the cases with localized OMAAV were positive for MPO-ANCA. The combination rate of glucocorticoids (GC) and immunosuppressants (IS) in localized OMAAV was high (80%), and the initial dosage of GC was similar to that in systemic OMAAV. Regarding the treatment outcomes, the rate of hearing improvement was high at 75%, and no patients experienced a relapse of localized OMAAV.
