Effect of a patient health engagement (PHE) model on rehabilitation participation in patients with acute myocardial infarction after PCI: a study protocol for a randomized controlled trial
No full textAbstract Background Participation in cardiac rehabilitation is low in patients with acute myocardial infarction (AMI) after percutaneous coronary intervention (PCI). Although existing rehabilitation methods have achieved certain results, patient participation in exercise rehabilitation is not ideal. The Patient Health Engagement (PHE) model is designed to ensure that patients improve their participation in cognitive, emotional, behavioral, and other aspects in all phases of exercise rehabilitation. The purpose of this study is to confirm whether the rehabilitation method based on the PHE model improves the rate of patient participation and enhances the rehabilitation effect during cardiac rehabilitation in patients with acute myocardial infarction compared with the traditional rehabilitation model. Methods/design This is a single-center, double-blind, randomized, controlled trial that will enroll 128 patients. Patients with stable acute myocardial infarction after undergoing PCI who received cardiac rehabilitation and postoperative LVEF ≥ 40%, categorized into Killip class I ~ II and with age ≥ 18 years, will be included in the study. Exclusion criteria are mainly malignant arrhythmias, acute heart failure, congestive heart failure, and patients requiring intra-aortic balloon counterpulsation. Patients will be randomized in a 1:1 ratio to the intervention (1) and control (2) groups. Physicians, rehabilitation specialists, patients, and data collectors will be blinded during the study. A rehabilitator and a specialist nurse will conduct the cardiac rehabilitation. The specialist nurse will hand over the sealed bag containing patient information (group 1 or 2) to the physician. Group 1 will undergo cardiac rehabilitation through the PHE model, three times a week for 3 months. The rehabilitation program will be evaluated and adjusted in time from each period of the rehabilitation. Group 2 will be treated with routine cardiac rehabilitation. The rehabilitation participation rate of the two groups will be evaluated before and after 3 months of intervention. The primary outcome will be the level of patient participation in rehabilitation, and the secondary outcome will include general data of patients, postoperative rehabilitation indicators, cardiac rehabilitation knowledge–attitude–practice questionnaire, cardiovascular adverse events, and a brief mood scale. Expected outcomes We expect improved cardiac rehabilitation participation rates and rehabilitation outcomes in patients with acute myocardial infarction after undergoing PCI using the PHE model. Discussion This approach may increase patient participation in rehabilitation, improve rehabilitation outcomes, and be widely implemented in hospitals and rehabilitation centers.

Obesity prevalence and time trend among youngsters in China, 1982-2002
No full textPurpose of present study is to describe the prevalence and trend of overweight and obesity, as well as its coexistence with stunting, among youngsters in China, from 1982 to 2002. Data from children 7-17 years of age from three cross-sectional national surveys: 1982 China National Nutrition Survey (5 334 boys and 4 793 girls), 1992 China National Nutrition Survey (8 048 boys and 7 453 girls) and 2002 China National Nutrition and Health Survey (23 242 boys and 21 638 girls) were used in this study. Overweight and obesity were defined according to age, sex specific BMI cut-off points from the International Obesity Task Force, while stunting was defined as height-for-age below -2 standard deviation from the NCHS/WHO reference median value. Results: Overweight prevalence of Chinese youngsters was 1.2%, 3.7% and 4.4%, while the obesity prevalence was 0.2%, 0.9% and 0.9% in 1982, 1992 and 2002, respectively. Both the overweight and obesity prevalence and their increment were higher among boys in urban areas. In 1982, 28.4% of overweight and 69.6% of obese youngsters were stunted, this decreased to 22.0% and 46.4% in 1992, and then to 5.7% and 7.7% in 2002, respectively. Conclusion: The prevalence of overweight and obesity in Chinese youngsters were low in 1982. There has been a rapid increase since then. If this trend continues, overweight will soon reach epidemic proportions. Stunting among overweight and obese youngsters decreased dramatically at the same time
Adipocyte Death Preferentially Induces Liver Injury and Inflammation Through the Activation of Chemokine (C‐C Motif) Receptor 2‐Positive Macrophages and Lipolysis
No full textAdipocyte death occurs under various physiopathological conditions, including obesity and alcohol drinking, and can trigger organ damage particularly in the liver, but the underlying mechanisms remain obscure. To explore these mechanisms, we developed a mouse model of inducible adipocyte death by overexpressing the human CD59 (hCD59) on adipocytes (adipocyte-specific hCD59 transgenic mice). Injection of these mice with intermedilysin (ILY), which rapidly lyses hCD59 expressing cells exclusively by binding to the hCD59 but not mouse CD59, resulted in the acute selective death of adipocytes, adipose macrophage infiltration, and elevation of serum free fatty acid (FFA) levels. ILY injection also resulted in the secondary damage to multiple organs with the strongest injury observed in the liver, with inflammation and hepatic macrophage activation. Mechanistically, acute adipocyte death elevated epinephrine and norepinephrine levels and activated lipolysis pathways in adipose tissue in a chemokine (C-C motif) receptor 2-positive (CCR2(+)) macrophage-dependent manner, which was followed by FFA release and lipotoxicity in the liver. Additionally, acute adipocyte death caused hepatic CCR2(+) macrophage activation and infiltration, further exacerbating liver injury. Conclusion: Adipocyte death predominantly induces liver injury and inflammation, which is probably due to the superior sensitivity of hepatocytes to lipotoxicity and the abundance of macrophages in the liver.
