CPAP improves sleep stability and attenuates acute nocturnal hypertension (NBPF) in OSA, with maximal benefits in severe cases by Liangcai Yu, Lan Shu, Simin Gao, Lin Li

“…NBPF was defined as the number of events per hour where nocturnal systolic blood pressure (SBP) increased by >12 mmHg.Results(1) Baseline characteristics: N1%, N2%, SBP, DBP, and NBPF significantly increased, while R% and N3% significantly decreased with increasing severity of OSA (p < 0.05). (2) Overall efficacy: After CPAP treatment, N1% significantly decreased, N3% significantly increased, and DBP and NBPF significantly decreased (p < 0.05). (3) Subgroup analysis: All patients experienced significant reductions in MAI, N1%, N2%, and NBPF, and significant increases in R% after CPAP treatment (p < 0.05); N3% significantly increased in moderate and severe patients (p < 0.05); SBP and DBP improvements were most significant in severe patients (p < 0.05). (4) Correlation and linear regression analysis: NBPF was significantly correlated with sleep structure parameters, showing an independent positive correlation with MAI (β = 0.375, p < 0.001) and an independent negative correlation with N3% (β = −0.143, p = 0.001).ConclusionThe first night of positive airway pressure (PAP) therapy significantly improves sleep architecture and effectively reduces nocturnal blood pressure while suppressing acute systolic blood pressure (NBPF) elevations in OSA patients, especially those with severe disease.…”

Research on Multi-Scenario Simulation of Urban Expansion for Beijing–Tianjin–Hebei Region Considering Multilevel Urban Flows by Jiayi Hu, Dongya Liu, Xinqi Zheng

“…Combining the urban flow model and the patch-generating land use simulation (PLUS) model, this study simulates and analyzes the process of urban expansion in the Beijing–Tianjin–Hebei (BTH) region, and investigates the impact of urban hierarchical structure differences on urban expansion. In this study, the role and influence of inter-city economy flow, transportation flow, population flow, and information flow on the development of urban agglomerations are comprehensively considered, and a multilevel urban interaction model is constructed based on a hierarchical generalized linear model (HGLM). …”
