Objective To explore the effect of multimodal interventions in improving the compliance rate of core infection control measures on reducing the incidence rate of vessel catheter associated infection (VCAI). Methods Inpatients with intravascular catheters in 5 departments with high rates of vascular catheterization and infection of Dongguan People’s Hospital between January 2021 and December 2022 were selected. According to the hospital stay, patients were divided into a pre-intervention group (January to December 2021) and a post-intervention group (January to December 2022). The core infection control measures assessment pass rates of medical staff between the two periods and the differences in the incidence rate of VCAI, average catheterization days, and catheterization rate before and after intervention in both groups were compared. Results A total of 8174 patients were included. Among them, there were 3915 patients in the pre-intervention group and 4259 patients in the post-intervention group. In the pre-intervention group, the total length of hospital stay was 122885 days, the total number of catheterization days was 48028 days, and 28 cases of VCAI occurred. In the post-intervention group, the total length of hospital stay was 126966 days, the total number of catheterization days was 51253 days, and 12 cases of VCAI occurred. After intervention, the compliance rate of VCAI core infection control measures was improved [69.21% (2907/4200) vs. 91.24% (3832/4200); χ2=642.090, P＜0.001], the pass rate of medical staff’s core infection control measures assessment was improved [53.33% (128/240) vs. 91.67% (220/240); χ2=88.443, P＜0.001], the catheterization rate was increased [39.08% (48028/122885) vs. 40.37% (51253/126966); χ2=42.979, P<0.001], and the incidence rate of VCAI was reduced [0.58‰ (28/48028) vs. 0.23‰ (12/51253); incidence-rate ratios =0.40, 95% confidence interval (0.20, 0.79), P=0.008]. Conclusions Improving the compliance rate of VCAI core infection control measures through multimodal interventions can significantly improve the passing rates of core infection control measures of medical staffs. This will help to reduce the incidence of VCAI and ensuring patient safety, provide evidence-based support for the prevention and control of VCAI.
Objective To summarize the experience of emergency coronary artery bypass grafting （CABG） after failed percutaneous coronary intervention. Methods From January 1998 to December 2002, 9 patients underwent emergency CABG after failed percutaneous coronary intervention. The indications of emergency CABG were coronary artery dissection （5 cases）or perforation （2 cases） and acute arterial occlusion （2 cases）. The time averaged 2 hours from onset of ischernia to revascularization. The CABG was performed under off-pump bypass in 3 cases and under CPB in 6 cases. The mean graft number was 3. Results There were no hospital death. The mean follow-up was 17 months. No death and angina occurred. The function of New York Heart Association class Ⅰ-Ⅱ were in 8 patients, class Ⅲ in 1 patient. Conclusion Emergency CABG is an effective management for failed percutaneous coronary intervention if the indication is right.
In 2020, due to the impact of the novel coronavirus epidemic, the development of transcatheter heart valve therapy has been shown to slow down, but there are still many aspects worth noting. The indication of monoclonal antibody after transcatheter aortic valve replacement (TAVR) should be further clarified. Low surgical risk patients were included in TAVR relative indications. Mitraclip G4 was approved by CE. The indication of atrial septal occlusion after mitraclip should be further clarified. The technique of coaptation augmentation is expected to become a new method of mitral valve interventional repair. Tendyne transcatheter mitral valve was approved by European Union. Transcatheter tricuspid valve treatment equipments, TriClip and PASCAL obtained CE mark. TAVR technology is being popularized rapidly in China, and what’s more, balloon dilated valve Sapien 3 and new recyclable repositioning valve system-Venus plus have entered the domestic market. A number of mitral valve therapeutic instruments have appeared one after another, and China's first tricuspid valve lux has completed its FIM research. Finally, with the improvement of devices and technology in the future, interventional therapy of heart valve is expected to benefit more patients.
Objective To evaluate the clinical efficacy of two-stage retrograde hybrid repair for acute aortic dissection involving the aortic arch complicated with distal malperfusion syndrome. Methods From May 2019 to December 2022, the patients presented with acute aortic dissection involving the aortic arch complicated with distal malperfusion syndrome treated in the Department of Cardiovascular Surgery of West China Hospital, Sichuan University were enrolled. After preoperative evaluation, all patients underwent priority emergency interventional surgery to improve distal malperfusion, and then underwent two-stage hybrid surgery to repair proximal aortic lesions. The perioperative clinical and imaging data were retrospectively analyzed. Results Five patients were collected, including 4 males and 1 female, with a median age of 58 years. The main manifestations were lower limb ischemia and renal insufficiency in 3 patients, and poor intestinal perfusion in 2 patients. All patients were given priority to interventional surgery to implant graft stents or bare stents and necessary branch artery intervention, and then successfully performed two-stage hybrid surgery, including type Ⅰhybrid surgery for 2 patients, type Ⅱ hybrid surgery for 1 patient and type Ⅲ hybrid surgery for the other 2 patients, with a success rate of 100.0%. All patients were discharged successfully, and the function of the organs with poor perfusion returned to normal. Only 1 patient recovered to grade 4 muscle strength of the diseased lower limbs upon discharge. No adverse events such as amputation, exploratory laparotomy and intestinal resection or long-term hemodialysis occurred. Conclusion The application of two-stage retrograde hybrid repair in the surgical treatment of acute aortic dissection involving the aortic arch complicated with distal malperfusion syndrome is safe and effective, and is helpful to improve the perioperative survival rate, and clinical outcomes of such patients.
Objective To develop a novel transcatheter tricuspid valve replacement device and test its performance. MethodsThe transcatheter tricuspid valve stent consisted of double-layer self-expanding nitinol stent, biotissue-derived bovine pericardial leaflets, and PTFE woven. The delivery system, mainly consisting of a handle control unit and a delivery sheath, was sent to the correct position via right atrium or jugular vein. The sheath had a visualization feature, and the handle control unit could realize the functions of stable release and partial recovery of the interventional valve. In addition, this study performed animal survival experiments on the basis of in vitro experiments. A large-white pig was used as the experimental animal. Cardiopulmonary bypass was established through median thoracotomy, then the right atrium was opened, and the interventional valve was released under direct vision without cardiac arrest. Approximately 1 month after interventional valve implantation, the maneuverability and stability of the interventional tricuspid device were evaluated by autopsy. ResultsThrough the animal experiment, the interventional valve was successfully released, and the anchoring was satisfactory. Postoperative transthoracic echocardiography showed that the interventional valve opened and closed well, the flow rate of tricuspid valve was 0.6 m/s, and there was no obvious tricuspid regurgitation. One month after the operation, we dissected the large-white pig and found the interventional valve was not deformed or displaced, the leaflets were well aligned, and there was thrombus attachment in the groove between the inner and outer layers of the interventional valve. ConclusionAnimal experiment shows that the novel device can stably and firmly attach to the tricuspid annulus, with good anchoring effect, and effectively reduce paravalvular leakage.
Diabetes and its complications that seriously threaten the health and life of human, has become a public health problem of global concern. Glycemic control remains a major focus in the treatment and management of patients with diabetes. The traditional lifestyle interventions, drug therapies, and surgeries have benefited many patients with diabetes. However, due to problems such as poor patient compliance, drug side effects, and limited surgical indications, there are still patients who fail to effectively control their blood glucose levels. With the development of bioelectronic medicine, neuromodulation techniques have shown great potential in the field of glycemic control and diabetes intervention with its unique advantages. This paper mainly reviewed the research advances and latest achievements of neuromodulation technologies such as peripheral nerve electrical stimulation, ultrasound neuromodulation, and optogenetics in blood glucose regulation and diabetes intervention, analyzed the existing problems and presented prospects for the future development trend to promote clinical research and application of neuromodulation technologies in the treatment of diabetes.
Objective To explore the current status of nutritional literacy in maintenance hemodialysis (MHD) patients and analyze its influencing factors. Methods MHD patients in Wenjiang Hemodialysis Center of West China Hospital, Sichuan University between January and April 2022 were selected by convenient sampling method. A questionnaire survey was conducted using the Nutrition Literacy Evaluation Scale for end-stage renal disease dialysis patients, and the current status and influencing factors of nutritional literacy in MHD patients were analyzed. Results A total of 214 patients were included, with an average nutritional literacy score of 19.14±5.78 for MHD patients. Among them, there were 60 cases (28.04%) of highly likely low nutritional literacy, 124 cases (57.94%) of moderate nutritional literacy, and 30 cases (14.02%) of highly likely high nutritional literacy. The correlation test results showed that hemoglobin, albumin, cholesterol, triglyceride, calcium, phosphorus, potassium, creatinine, estimated glomerular filtration rate, and nutritional literacy scores were not correlated. The results of multiple linear stepwise regression analysis showed that education level [non-standardized partial regression coefficient (b)=1.821, 95% confidence interval (CI) (1.143, 2.498), P<0.001], age [b=−2.460, 95%CI (−4.247, −0.672), P=0.007], hypertensive kidney damage [b=2.233, 95%CI (0.428, 4.039), P=0.016] were all factors affecting the nutritional literacy of MHD patients. Conclusions In clinical work, more attention should be paid to MHD patients with low educational level, older age, and more primary diseases. And targeted interventions should be adopted to improve the level of nutritional literacy in order to improve the quality of life of MHD patients.
ObjectiveTo study effect of different surgical treatments for patent ductus arteriosus in children.MethodA total of 38 patients with patent ductus arteriosus who underwent surgical treatment of cardiothoracic surgery between January 2016 and December 2017 in our hospital were as an observation group (12 patients with severing suture, 26 patients with ligation, 14 males and 24 females, aged 0.08–8.67 years). In the same period, 38 patients with patent ductus arteriosus who underwent interventional closure in the Department of Cardiology were as a control group (17 males and 21 females, aged 0.50–5.42 years). The clinical effectiveness of the two groups was compared.ResultsThe operation time, postoperative hospital stay, and blood transfusion rate in the observation group were higher than those in the control group with statistical differences (P<0.05). There was no statistical difference in intraoperative blood loss and complications between the two groups.ConclusionsIn patients with a single patent ductus arteriosus or a small catheter, interventional closure of the patent ductus arteriosus is less trauma and faster recovery. But in patients with lower weigh, premature, other intracardiac malformations, large catheter, moderate or severe pulmonary hypertension, the surgery is better.
ObjectiveTo analyze the short-term clinical efficacy and prognosis of one-stop transcatheter aortic valve replacement (TAVR)+percutaneous coronary intervention (PCI) in the treatment of aortic valve disease with coronary heart disease. MethodsThe clinical data of patients with aortic valve disease complicated with coronary heart disease who underwent one-stop TAVR+PCI treatment at the Department of Cardiovascular Surgery, the Second Hospital of Hebei Medical University from January 2018 to June 2023 were retrospective analyzed. The preoperative and postoperative clinical data were compared, and 1-month follow-up results were recorded. ResultsA total of 37 patients were enrolled, including 22 males and 15 females, with an average age of 69.14±6.47 years. Thirty-six patients recovered and were discharged after the surgery, and 1 (2.7%) patient died during the surgery. Self-expanding TAVR valves were implanted through the femoral artery in all patients. One coronary artery was opened by PCI in 35 (94.6%) patients, and two coronary arteries were opened by PCI in 2 (5.4%) patients. All PCI opened arteries had a stenosis>70%. During the postoperative hospitalization, the complications included pulmonary infection in 11 (30.6%) patients, severe pneumonia in 10 (27.8%) patients, liver function injury in 14 (38.9%) patients, renal function injury in 5 (13.9%) patients, cerebral infarction in 1 (2.8%) patient, atrial fibrillation in 1 (2.8%) patient, ventricular premature beats in 2 (5.6%) patients, atrioventricular block in 2 (5.6%) patients, and complete left bundle branch block in 5 (13.9%) patients. The median postoperative ventilation assistance time was 12.0 (0.0, 17.0) h, the ICU monitoring time was 1.0 (0.0, 2.0) d, and the postoperative hospitalization time was 5.0 (4.0, 7.0) d. There was a significant improvement in the New York Heart Association cardiac function grading after surgery (P<0.001). After surgery, there were 21 (58.3%) patients had minor perivalve leakage, 6 (16.7%) patients had minor to moderate perivalve leakage, and no moderate or above degree of perivalve leakage. After one month of postoperative follow-up, 36 patients showed significant improvement in heart function. There were no patients with recurrent acute coronary syndrome, re-PCI, or cardiovascular system disease related re-hospitalization. ConclusionThe one-stop TAVR+PCI treatment for patients with aortic valve disease and coronary heart disease can obtain satisfactory short-term clinical efficacy, which is worth further trying and studying.
Shortly after the earthquake in Min county and Zhang county, the department of health of Gansu province immediately established a leadership team for earthquake relief and medical rescue, subordinated by psychological crisis intervention teams, which was responsible for training relevant personnel to carry out psychological intervention, and spreading related knowledge about earthquake. Then, emergency psychological intervention was provided for the key population (more than 90 times in total, involving 8 194 person-times). We also offered individualized psychological services (617 person-times), and diagnosed 31 patients with mental disorders through consultation. After the earthquake, the emotion of victims including depression, anxiety and acute stress disorder increased. The workload of psychological crisis intervention after earthquake was heavy and hard. However, Gansu province needs national support due to poor resources.
