ABSTRACT
Objectives: To explore the effectiveness of the mobile app-based multidisciplinary exercise management on patients who receive percutaneous coronary intervention (PCI). Methods: From January to October 2020, 54 patients after PCI were randomly assigned to the intervention group (n = 27) and the control group (n = 27). The intervention group received the mobile app-based multidisciplinary exercise management, whereas the control group received routine care. The patients after PCI began to take intervention one month after the operation, and the intervention lasted for two months. Before and after the intervention, 6-Minute Walking Distance was used to evaluate the patient's exercise tolerance, and the patient's exercise compliance was evaluated according to the patient's exercise status recorded by the mobile app. The cognitive questionnaire on knowledge about PCI treatment for Coronary Heart Disease, the Self-efficacy for Chronic Disease Scale and the Perceived Social Support Scale were used to evaluate patients' disease-related cognition, self-efficacy and perception of social support. This study was registered on Clinical Trials.gov with registration number ChiCTR2000028930. Results: Totally 51 patients after PCI who completed this study (25 patients in the intervention group and 26 patients in the control group) were included in the analysis. After 2 months of intervention, the exercise compliance of patients in the intervention group was better than that in the control group. And 6-Minute Walking Distance (469.36 ± 57.48 vs. 432.81 ± 67.09), and the scores of knowledge of PCI treatment for coronary heart disease (52.64 ± 9.82 vs. 42.42 ± 8.54), Self-efficacy for Chronic Disease Scale (42.40 ± 8.04 vs. 36.88 ± 7.73) and Perceived Social Support Scale (74.04 ± 5.73 vs. 66.69 ± 6.86) in the intervention group were higher than those in the control group with statistical significance (P < 0.05). Conclusions: The multidisciplinary exercise management based on the mobile app can effectively improve exercise tolerance, exercise compliance, disease-related cognition, self-efficacy, and perception of social support during exercise training for patients after PCI.
ABSTRACT
OBJECTIVES: To analyze the correlations between family care, coping strategies and the subject well-being (SWB) of patients with coronary heart disease (CHD) after percutaneous coronary intervention (PCI). METHODS: From November 2019 to October 2020, 264 CHD patients who had undergone PCI were enrolled in this questionnaire survey. The research tools applied included General Information Questionnaire, the Adaptation, Partnership, Growth, Affection and Resolve, Medical Coping Modes Questionnaire, and the General Well-being Schedule. SPSS 24.0 and Amos 23.0 software packages were used for statistical analysis. RESULTS: The mean scores for family care, confrontation, avoidance, acceptance-resignation and SWB, were 7.59 ± 2.24, 20.03 ± 3.78, 16.49 ± 2.70, 10.42 ± 2.01, and 73.31 ± 11.63, respectively. Subgroup analysis showed that the path coefficient between family care and subjective well-being was higher in males than females. Family care was directly related to coping strategies. The coping strategies were directly related to SWB, while family care showed an indirect association with SWB via coping strategies. CONCLUSIONS: Family care can improve CHD patients' SWB post-PCI, and coping strategies are important for the link between family care and SWB. Also, men received more family care than women. Based on a patient's characteristics, healthcare providers can promote patients' positive coping strategies, increase their perceived family care, and improve the patient's SWB.
ABSTRACT
Four novel isopolymolybdate-based coordination polymers (CPs), constructed from 2,6-bis(1,2,4-triazol-1-yl)pyridine (btp), 1,3-bis(4H-1,2,4-triazol-4-yl)benzene (btb), and 3,5-bis(1-imidazolium)pyridine (bip), have been synthesized under a hydrothermal method: {[Co(btp)(H2O)2(ß-Mo8O26)0.5]·3H2O}n (1), [Ni(btp)(H4Mo6O22)0.5]n (2), [Co(btb)(H2O)(ß-Mo8O26)0.5]n (3), and {[Co(Hbip)2(H2O)2(γ-Mo8O26)]·6H2O}n (4). Complex 1 exhibits one 3D framework with an unexpected 3-nodal 2,4,6-c net topology containing the 1D {ß-Mo8O26}n chains, 6-connected CoII centers, and V-type coordinated btp ligands. The neighboring [Mo6O22]4- anions of complex 2 are bridged by the NiII centers to build one 2D {Ni2(Mo6O22)} network, which is arranged into the 3D framework through the weak π···π stacking interactions. In compound 3, one 3D framework is formed by the adjacent 1D {Co2(btp)2}n chains connected by {ß-Mo8O26}n units, which demonstrates a rare 4,6-c fsc topology. In complex 4, one 2D {Co(Hbip)2(γ-Mo8O26)} layer with a (4, 4) network is connected to one 3D hydrogen-bonding framework via N-H···O and O-H···O hydrogen bonds. Magnetic data indicate that complexes 1 and 4 exhibit antiferromagnetic behaviors, whereas complexes 2 and 3 reveal spin-canting magnetic behavior and metamagnetic behavior, respectively. In addition, the proton conductivity of complexes 3 and 4 was investigated, showing that compound 4 has good proton conductivity at 85 °C and a relative humidity of 98% RH.
ABSTRACT
PURPOSE: To study the effect of adolescent premolar scissor bite on the sagittal position of mandible and provide proper reference for correct orthodontic diagnosis and right time to treatment. METHODSï¼ One hundred adolescents (54 females, 46 males) with scissor bite of premolars(70 were unilateral,30 were bilateral) were selected as experimental group between 2004 to 2017 from the Department of Orthodontics, Stomatological Hospital of China Medical University. Among them, 54 females served as female group, 46 males served as male group; 30 were bilateral and 70 were unilateral. Lateral cephalograms were recorded before treatment. 16 sagittal hard tissue variables on maxilla and mandible were measured cephalometrically by Winceph 9.0 software, and the cephalometric data were analyzed statistically by using SPSS 21.0 software package. RESULTS: Compared with normal occlusion, Beta angle, SNB, SND, ANB, AB-Plane angle, APDI, convexity angle, facial angle, Wits, Co-Po showed statistically significant difference in both unilateral group and bilateral group (P<0.05). In addition, Go-Pog showed statistically significant difference between normal occlusion and unilateral group(P<0.05). CONCLUSIONS: Adolescents with premolar scissor bite restricts the sagittal position of mandible and tend to have skeletal â ¡ sagittal jaw relationship. Scissor bite affects the growth of mandible and makes mandibular body length and mandibular length less than normal. More attention should be paid to scissor bite as early as possible to decrease the harmful effects on growth of mandible and sagittal jaw relationship.
