Effectiveness of a nurse-led multidisciplinary self-management program for patients with coronary heart disease in communities: A randomized controlled trial

ObjectiveTo examine the effectiveness of a nurse-led multidisciplinary self-management program (NMSP) on self-management behaviors, self-efficacy, health-related quality of life (HRQoL) and unplanned health service utilization (HSU) among Chinese patients with coronary heart disease (CHD) in communities.MethodsA randomized controlled trial with repeated measurements was used. A convenience sample of 144 participants was recruited from a community health center in China. All participants were randomly assigned to an intervention group (n = 72) in the newly developed NMSP or a control group (n = 72) in routine care. Outcome measurement was performed at baseline, 3 months and 6 months using Coronary Artery Disease Self-Management Scale (CADSs), Self-efficacy for Chronic Disease 6-item Scale (SECD6), and Short Form-12 health survey questionnaire (SF-12).ResultsOver the six months, the two groups reported significant differences in disease medical and emotional management of CADSs, confidence in symptom and disease management of SECD6, physical and mental component summary of SF-12, as well as emergency and outpatient visits of unplanned HSU.ConclusionsThe NMSP improves self-management behaviors, self-efficacy, HRQoL and reduces unplanned HSU among CHD patients in communities.Practice implicationsThis study provides an effective approach to empower CHD patients with emphasizing on collaboration support of health professionals in communities.     

International Hand Function Study Following Distal Radial Access: The RATATOUILLE Study

BackgroundDistal radial access (DRA) has been proposed to improve procedure ergonomics and favor radial artery patency. Although promising data, nothing is known on evolving hand function after DRA.ObjectivesThis study sought to comprehensively evaluate hand function in patients undergoing DRA.MethodsReal-world patients undergoing DRA undertook a thorough multimodality assessment of hand function implementing multidomain questionnaires (Disabilities of the Arm, Shoulder and Hand and Levine-Katz), and motor (pinch grip test) and sensory (Semmes-Weinstein monofilaments test) examinations of both hands. All assessments were performed at preprocedural baseline and planned at 1-, 6-, and 12-month follow-up (FU). Adverse clinical and procedural events were documented too.ResultsData of 313 patients (220 men, age 66 ± 10 years) from 9 international centers were analyzed. The Disabilities of the Arm, Shoulder and Hand and the Levine-Katz scores slightly improved from baseline to FU (P = 0.008 and P = 0.029, respectively). Pinch strength mildly improved from baseline to FU (P < 0.001 for both the left and right hands). Similarly, touch pressure threshold appeared to faintly improve in both the left and right hands (P < 0.012 for all the sites). For both motor and sensory function tests, comparable findings were found for the DRA hand and the contralateral one, with no significant differences between them. Repeated assessment of all tests over all FU time points similarly showed lack of worsening hand function. Access-related adverse events included 19 harmless bleedings and 3 forearm radial artery and 3 distal radial artery occlusions. None affected hand function at FU.ConclusionsIn a systematic multidimensional assessment, DRA was not associated with hand function impairment. Moreover, DRA emerges as a safe alternative vascular access.

Association between de novo lipogenesis susceptibility genes and coronary artery disease

Background and aimsCoronary artery disease (CAD) is the principal cause of death in individuals with non-alcoholic fatty liver disease (NAFLD). The aim of this study was to use genetic epidemiology to study the association between de novo lipogenesis (DNL), one of the major pathways leading to NAFLD, and CAD risk.Methods and resultsDNL susceptibility genes were used as instruments and selected using three approaches: 1) genes that are associated with both high serum triglycerides and low sex hormone-binding globulin, both downstream consequences of DNL (unbiased approach), 2) genes that have a known role in DNL (biased approach), and 3) genes that have been associated with serum fatty acids, used as a proxy of DNL. Gene-CAD effect estimates were retrieved from the meta-analysis of CARDIoGRAM and the UK Biobank (～76014 cases and ～264785 controls). Effect estimates were clustered using a fixed-effects meta-analysis. Twenty-two DNL susceptibility genes were identified by the unbiased approach, nine genes by the biased approach and seven genes were associated with plasma fatty acids. Clustering of genes selected in the unbiased and biased approach showed a statistically significant association with CAD (OR:1.016, 95%CI:1.012; 1.020 and OR:1.013, 95%CI:1.007; 1.020, respectively), while clustering of fatty acid genes did not (OR:1.004, 95%CI:0.996–1.011). Subsequent exclusion of potential influential outliers did reveal a statistically significant association (OR:1.009, 95%CI:1.000; 1.018).ConclusionsDNL susceptibility genes are associated with an increased risk of CAD. These findings suggest that DNL may be involved in the pathogenesis of CAD and favor further development of strategies that target NAFLD through DNL.

目的:探讨术前减轻黄疸对壶腹部癌患者行Whipple手术治疗效果的影响。方法:回顾性分析2012年1月—2018年7月45例在Whipple手术术前行减轻黄疸治疗的壶腹部癌患者(减轻黄疸组)的临床资料,与同期34例行Whipple手术术前未行减轻黄疸治疗的壶腹部癌患者(未减轻黄疸组)的临床资料进行比较。比较两组患者术前、术中情况(手术时间、出血量、输血量)和术后并发症的差异。结果:减轻黄疸组患者治疗后总胆红素(TBil)、结合胆红素(DBil)、谷丙转氨酶(ALT)与治疗前比较差异有统计学意义(P<0.05)。两组R 0切除率比较差异无统计学意义(P>0.05)。减轻黄疸组手术时间、术中出血量、术中输血量优于未减轻黄疸组,差异均有统计学意义(P<0.05)。减轻黄疸组术后并发症发生率、胰漏发生率和胆漏发生率少于未减轻黄疸组,差异均有统计学意义(P<0.05)。结论:壶腹部癌患者行Whipple手术术前彻底减轻黄疸,可以缩短手术时间,减少术中出血量和术后并发症的发生。

Stage 1 acute kidney injury is independently associated with infection following cardiac surgery

ObjectivesSevere acute kidney injury (AKI) is a known risk factor for infection and mortality. However, whether stage 1 AKI is a risk factor for infection has not been evaluated in adults. We hypothesized that stage 1 AKI following cardiac surgery would independently associate with infection and mortality.MethodsIn this retrospective propensity score–matched study, we evaluated 1620 adult patients who underwent nonemergent cardiac surgery at the University of Colorado Hospital from 2011 to 2017. Patients who developed stage 1 AKI by Kidney Disease Improving Global Outcomes creatinine criteria within 72 hours of surgery were matched to patients who did not develop AKI. The primary outcome was an infection, defined as a new surgical-site infection, positive blood or urine culture, or development of pneumonia. Secondary outcomes included in-hospital mortality, stroke, and intensive care unit (ICU) and hospital length of stay (LOS).ResultsStage 1 AKI occurred in 293 patients (18.3%). Infection occurred in 20.9% of patients with stage 1 AKI compared with 8.1% in the no-AKI group (P < .001). In propensity-score matched analysis, stage 1 AKI independently associated with increased infection (odds ratio [OR]; 2.24, 95% confidence interval [CI], 1.37-3.17), ICU LOS (OR, 2.38; 95% CI, 1.71–3.31), and hospital LOS (OR, 1.30; 95% CI, 1.17-1.45).ConclusionsStage 1 AKI is independently associated with postoperative infection, ICU LOS, and hospital LOS. Treatment strategies focused on prevention, early recognition, and optimal medical management of AKI may decrease significant postoperative morbidity.
