In exploring the mechanisms of behavioral change for hypertension control, a study based on the transtheoretical model was carried out in Taiwan in 2000, with a sample of 350 hypertensive adults living in Taipei urban and rural areas. The relationships among stages of change, processes of change, and demographic factors were analyzed for six health behaviors: low-fat food consumption, alcohol use, smoking, physical activity, weight control and routine blood pressure check-ups. The results showed that rural populations had greater difficulty than urban populations in avoiding smoking and engaging in physical activity, and the processes of change being used by urban populations were significantly greater than rural populations for diet, physical activity and routine blood pressure check-up. Individuals who use more processes of change will be more inclined to move from the pre-contemplation stage to the maintenance stage. Social liberation, self-reevaluation and counterconditioning were very important processes for changing diet behavior, engaging in physical activity and checking blood pressure on a regular basis.

Hemodynamic comparisons of different shunt positions and geometrical model simplification strategies in the simulation of transjugular intrahepatic portosystemic shunt (TIPS).
Sci Rep

School of Gongli Hospital Medical Technology, University of Shanghai for Science and Technology, No. 516 Jungong Road, Yangpu District, Shanghai, 200093, China.
Transjugular intrahepatic portosystemic shunt (TIPS) is a widely used surgery for portal hypertensive patients, whose potential postoperative complications are closely related to the hemodynamic condition of the portal venous system. The selection of shunt position in the surgery may affect the postoperative hemodynamics; however, it is difficult for clinical studies to investigate the influence. Therefore, this study aims to employ the computational model simulating TIPS to compare the hemodynamic differences resulting from different shunt positions, and also to investigate the influences of different geometrical model simplification strategies used in the TIPS simulation.

Background: Intermediate-high risk pulmonary embolism (PE) carries a significant risk of hemodynamic deterioration or death. Treatment should balance efficacy in reducing clot burden with the risk of complications, particularly bleeding. Previous studies on high-dose, short-term thrombolysis with alteplase (rtPA) showed a reduced risk of hemodynamic deterioration but no change in mortality and increased bleeding complications.

Background: Albumin, a vital component in regulating human blood oncotic pressure, plays an important role in the prediction of prognosis in pediatric patients.Previous research identified significant differences in serum albumin levels of healthy and critically ill children.
Methods: The present study aims to investigate the correlation between albumin levels measured during pediatric intensive care unit(PICU) admission and clinical outcomes.
HIF-1α mediates hypertension and vascular remodeling in sleep apnea via hippo-YAP pathway activation.

Department of Otorhinolaryngology/Head and Neck, Sir Run Run Shaw Hospital, Zhejiang University School of Medicine, No.3 East Qingchun Road, Hangzhou, 310020, Zhejiang, China.
Background: Sleep apnea syndrome (SAS) is associated with hypertension and vascular remodeling. Hypoxia-inducible factor-1α (HIF-1α) and the Hippo-YAP pathway are implicated in these processes, but their specific roles remain unclear. This study investigated the HIF-1α/Hippo-YAP pathway in SAS-related hypertension.

Background: Maternal hemoglobin (Hb) is related to nutritional status, and it widely fluctuates during pregnancy. However, the relationship between Hb and blood pressure (BP) during pregnancy is unclear. This study aimed to estimate the associations between maternal Hb in various trimesters and its changes with BP during pregnancy.
