Relationship between primary caregivers' social support function, anxiety, and depression after interventional therapy for acute myocardial infarction patients.

BACKGROUND: An acute myocardial infarction (AMI) is often treated with direct coronary intervention and requires home-based rehabilitation. Caregivers of patients with AMI need adequate social support to maintain high-quality care; however, their social support function is low, and relevant indicators for intervention must be identified. AIM: To analyze the correlation between social support for primary caregivers, their anxiety, and depression, when caring for patients with AMI after interventional therapy. METHODS: Using convenience sampling, we selected 300 primary caregivers of patients with AMI who had undergone interventional therapy. The Social Support Rating Scale (SSRS), Self-Rating Anxiety Scale (SAS), and Self-Rating Depression Scale (SDS) were used to assess the primary caregivers. A Pearson's correlation analysis was used to analyze the correlations between the SSRS, SAS, and SDS, and a multiple logistic regression analysis was used to analyze the factors influencing the low social support function of primary caregivers. The receiver operating characteristic curve and area under the curve (AUC) were used to evaluate the pre-dictive ability of the SAS and SDS for low social support function in primary caregivers. RESULTS: Considering the norm among Chinese people, AMI caregivers' objective support, subjective support, support utilization, and SSRS scores were lower, while their SAS and SDS scores were higher. The SSRS scores of female caregivers were higher than those of the male caregivers (t = 2.123, P = 0.035). The Pearson correlation analysis showed that objective support, subjective support, support utilization, and SSRS total scores were significantly correlated with both SAS (r = -0.414, -0.460, -0.416, -0.535) and SDS scores (r = -0.463, -0.379, -0.349, -0.472). Among the 300 AMI caregivers, 56 cases (18.67%) had a low level of support function (SSRS ≤ 22 points). Logistic regression model analysis showed that SAS and SDS were independent risk factors for low social support function of AMI caregivers, regardless of adjustment for other variables (P < 0.05). SAS and SDS predicted that the AUC of AMI caregivers with low support function was 0.84, sensitivity was 67.9 and 71.4, and specificity was 84.0 and 70.9, respectively. CONCLUSION: The social support function of the primary caregiver of patients with AMI after interventional therapy was lower and negatively correlated with anxiety and depression in the primary caregiver.

Design, Synthesis and Molecular Docking of 1,3,4-Oxadiazole-2(3H)-thione Derivatives Containing 1,4-Benzodioxane Skeleton as Potential FabH Inhibitors.

Fatty acid biosynthesis is essential for bacterial survival. Of these promising targets, ß-ketoacyl-acyl carrier protein (ACP) synthase III (FabH) is the most attractive target. A series of novel 1,3,4-oxadiazole-2(3H)-thione derivatives containing 1,4-benzodioxane skeleton targeting FabH were designed and synthesized. These compounds were determined by 1 H-NMR, 13 C-NMR, MS and further confirmed by crystallographic diffraction study for compound 7m and 7n. Most of the compounds exhibited good inhibitory activity against bacteria by computer-assisted screening, antibacterial activity test and E. coli FabH inhibitory activity test, wherein compounds 7e and 7q exhibited the most significant inhibitory activities. Besides, compound 7q showed the best E. coli FabH inhibitory activity (IC50 =2.45 µΜ). Computational docking studies also showed that compound 7q interacts with FabH critical residues in the active site.

Design, Synthesis and Molecular Docking of Novel Quinazolinone Hydrazide Derivatives as EGFR Inhibitors.

A series of novel quinazolinone hydrazide derivatives were designed and synthesized as EGFR inhibitors. The results indicated that most of the aimed compounds had potential anti-tumor cell proliferation and EGFR inhibitory activities. In the comprehensive analysis of all the tested compounds, the target compound 9c showed the best anti-tumor cell proliferation activity, (IC50 =1.31 µM for MCF-7, IC50 =1.89 µM for HepG2, IC50 =2.10 µM for SGC), and IC50 =0.59 µM for the EGFR inhibitory activity. Docking results showed that compound 9c could ideally insert the active site and interact with the critical amino acid residues (Val702, Lys721, Met769, Asp831) in the active site.

3-Year Outcomes of the ULTIMATE Trial Comparing Intravascular Ultrasound Versus Angiography-Guided Drug-Eluting Stent Implantation.

OBJECTIVES: The aim of this study was to explore the difference in target vessel failure (TVF) 3 years after intravascular ultrasound (IVUS) guidance versus angiographic guidance among all comers undergoing second-generation drug-eluting stent (DES) implantation. BACKGROUND: The multicenter randomized ULTIMATE (Intravascular Ultrasound Guided Drug Eluting Stents Implantation in "All-Comers" Coronary Lesions) trial showed a lower incidence of 1-year TVF after IVUS-guided DES implantation among all comers compared with angiographic guidance. However, the 3-year clinical outcomes of the ULTIMATE trial remain unknown. METHODS: A total of 1,448 all comers undergoing DES implantation who were randomly assigned to either IVUS guidance or angiographic guidance in the ULTIMATE trial were followed for 3 years. The primary endpoint was the risk for TVF at 3 years. The safety endpoint was definite or probable stent thrombosis (ST). RESULTS: At 3 years, TVF occurred in 47 patients (6.6%) in the IVUS-guided group and in 76 patients (10.7%) in the angiography-guided group (p = 0.01), driven mainly by the decrease in clinically driven target vessel revascularization (4.5% vs. 6.9%; p = 0.05). The rate of definite or probable ST was 0.1% in the IVUS-guided group and 1.1% in the angiography-guided group (p = 0.02). Notably, the IVUS-defined optimal procedure was associated with a significant reduction in 3-year TVF relative to that with the suboptimal procedure. CONCLUSIONS: IVUS-guided DES implantation was associated with significantly lower rates of TVF and ST during 3-year follow-up among all comers, particularly those who underwent the IVUS-defined optimal procedure compared with those with angiographic guidance.
