Patients with diabetic retinopathy often experience diabetes distress when facing the challenges of the disease, which has adverse effects on their health outcomes. This paper summarizes the current situation of diabetes distress in patients with diabetic retinopathy, and the assessment tools, influencing factors, and intervention measures, aiming to provide a reference for healthcare professionals to conduct intervention studies.

Objective To construct an intervention program for diabetic retinopathy(DR)patients undergoing surgery based on the theory of'Timing It Right'.Methods Guided by the theory of'Timing It Right',based on literature review and semi-structured interview,the first draft of the intervention program was formulated.From December 2022 to February 2023,15 medical and nursing experts in ophthalmology and endocrinology from 5 provinces(cities)in Zhejiang,Sichuan,Shanxi,Chongqing and Shanghai were interviewed by Delphi expert for 2 rounds to seek their advice and revision,and the final draft was formed.Results The effective recovery rate of 2 rounds of expert consultations was 93.75％and 100％.The authority coefficients were 0.87.The importance and feasibility of Kendall'W coordination coefficients were 0.325,0.138 and 0.193,0.141 in 2 rounds,respectively(P＜0.001).The finalized intervention program consisted of 6 months,which included 5 first-level items,18 second-level items and 43 third-level items.Conclusion The intervention program for DR patients undergoing surgery based on the theory of'Timing It Right'is reliable,scientific,feasible and practical,and it can meet the needs of such patients,providing a reference for improving their self-management ability,improving their negative emotions and delaying disease progression.

Objective:To examine the early and midterm surgical outcome of pulmonary atresia with ventricular septal defect and major aortopulmonary collateral arteries (PA/VSD/MAPCA) using revised surgical strategies.Methods:A retrospective analysis of clinical data, surgical methods, and follow-up results was performed of 104 cases of PA/VSD/MAPCA in Department of Cardiovascular Surgery, Guangzhou Women and Children′s Medical Center from January 2017 to September 2022. There were 55 males and 49 females, aged ( M(IQR)) 33.9(84.0) months (range: 0.5 to 209.6 months) at the first surgical procedures. The anatomical classification included 89 cases of type B and 15 cases of type C. The number of major aortopulmonary collateral arteries was 4.2 (3.0) (range: 1 to 8). The Kaplan-Meier method was used for survival estimation. Results:In the first stage of surgery, 50 patients underwent a complete primary repair, 12 patients underwent partial repair, 32 patients underwent palliative right ventricular-pulmonary artery connection, and only 10 patients chose the Blalock-Taussig shunt. There were 10 cases of early death. In the second stage, 14 patients underwent complete repair and 4 patients underwent partial repair with no early death. The interval between the two surgeries was 19 (10) months (range: 9 to 48 months). Finally, during the 40 (34) months follow-up period, a total of 64 patients were complete repair and the right/left ventricular pressure ratio after complete repair was 0.63±0.16 (range: 0.36 to 1.00). Survival analysis showed that survival rates at 1 and 5 years after first-stage surgery were both 89.4% (95% CI: 83.5% to 95.3%). At 28 (34) months (range: 1 to 67 months) of follow-up after complete repair, the survival analysis showed that the survival rates at 1 and 5 years were both 95.2% (95% CI: 89.9% to 100%). Conclusions:Using combined approaches tailored to individual patients and optimized unifocalization strategy, the complete repair rate at one stage and the cumulative complete repair rate at 5 years improved significantly with a lower right/left ventricular pressure ratio and satisfactory early and intermediate survival.

Objective:To summarize the early and middle terms of the revascularization of remnant pulmonary artery in unilateral absent intrapericardial pulmonary artery.Methods:We retrospectively analyzed the medical records of 14 patients(7 males and 7 females) with unilateral absent pulmonary artery, in which 10 were right and 4 were left, the median age at surgery was 5 months. The patients received operation from January 2009 to December 2020. 14 patients, 2 cases associated with tetralogy of Fallot, and 1 case with aortopulmonary window. The diagnosis was made by enhanced CT scan or pulmonary vein wedge angiography. The median diameter of the affected hilar pulmonary artery remnants was(3.20±0.94)mm, and the Z value was -3.92±1.64. All the patients received single-stage revascularization: group A: tube graft interposition in 3 patients, autologous pericardial roll in 5; group B: direct anastomosis in 2, unifocalization in one and main pulmonary artery flap angioplasty in the rest 3.Results:No hospital death occurred. There were no difference finds in the age and weight at operation, the cardiopulmonary bypass time, the mechanical ventilation time, and the length of intensive care unit stay between the two groups. All the patients took aspirin for anticoagulation for 6 months after the operation. The follow-up period was 1 month to 68 months. Because the neo-PA stenosis at the anastomosis was found in one patient in group B, transcatheter balloon angioplasty was performed at 41 months after surgery. Nonetheless, the results were encouraging, symptoms have improved in all patients. The diameter and Z value of the latest ipsilateral pulmonary artery was(6.25±0.99)mm and -2.34±1.18 respectively, significantly improved when compared to the preoperative value. Residual pulmonary artery hypertension was not found. The Z value of the affected side of the pulmonary artery in group B was significantly improved than that in group A.Conclusion:Early and aggressive pulmonary artery revascularization is effective at restoring normal antegrade flow to the affected lung, resulting in improved diameter of the PA, and UAPA patient’s symptoms. The use of autologous pulmonary artery tissue angioplasty may reach a more satisfying result. However, transcatheter intervention may diminish the new pulmonary artery stenosis temporarily, reoperation is still needed in the long-term follow-up.

Objective:To evaluate the early results of pulmonary autograft mitral valve replacement (Ross Ⅱ procedure) in infants with intractable congenital mitral valve lesions.Methods:Between August 2018 and September 2019, 6 infants underwent mitral valve replacement with a pulmonary autograft in Department of Cardiovascular Surgery, Guangzhou Women and Children′s Medical Center. There were 2 males and 4 females.The age at surgery ranged from 50 days to 1 year old.Preoperative diagnoses included severe to critic mitral valve insuffiency in all patients, moderate mitral valve stenosis in 3 patients, and mitral valve prolapse in one. When the pulmonary autograft was harvested, a cuff of bovine or autologous pericardium was sewn onto the proximal (infundibular) end of the autograft ( "top-hat" configuration). The distal (pulmonary) end of the autograft was secured to the mitral annulus.At the level of the left atrial free wall, the pericardial cuff was progressively tailored and sewn onto the atrial wall to remain away from the ostia of the pulmonary veins and to maintain normal morphology of the autograft. The bovine jugular valved conduit was used to reconstruct the right ventricular outflow tract.Results:There was one early death due to sudden cardiac arrest at the night of surgery day. The remaining 5 patients were successfully recovered and discharged. Follow-up of survivors ranged from 3 to 13 months. Echocardiographic follow-up demonstrated the flow velocity across the mitral valve position was 1.5 to 2.3 m/s, with a means gradient of 4 to 6 mmHg (1 mmHg=0.133 kPa). Four patients showed mild mitral insuffiency, normal left atrium and ventricle size and left ventricle ejection fraction.One patient had moderate mitral insuffiency, pulmonary valve endocarditis, and reduced left ventricle ejection fraction. The clinical symptoms of all survivals improved significantly and the weight gain were satisfactory.Conclusion:Pulmonary autograft mitral valve replacement may be a feasible and effective remedial surgical strategy for young infants with intractable congenital mitral valve lesions.

Objective To summarize the outcomes and experience of arterial switch operation (ASO) in the past 10 years in our center.Methods From September 2008 to July 2017,238 patients underwent ASO at Guangzhou Women and Children Medical Center for repair of transposition of the great arteries and Taussig-Bing anomaly.There were 193 male and 45 female.Median age at operation was 2 months (2 days to 10 years) and mean body weight was(4.2 ± 1.7) kg (1.8-20.6 kg).There were TGA and VSD 91 cases,TGA/IVS 110 cases,and Taussig-Bing anomaly 37 cases.Among them 24 patients had an aortic arch anomaly.Intramural coronary artery was found in 8 patients.Results All patients successfully completed the operation,one-stage ASO was perfonned in 232 patients.Two-stage ASO was performed in 6 patients.The mortality was 14.2％.The follow-up duration was 1-10 years (median time,46 mouths).There were 3 died.Two suffered sudden death,and another one arrhythmia.10-year survival rate was 92.8％.Conclusion The outcomes of ASO were satisfactory.The long-term reoperation rate was rare.

Objective To review the early-and mid-term results of anatomic repair or Fontan pathway for congenitally corrected transposition of the great arteries(ccTGA) in a single institution of China.Methods Hospital records over a 9-year period(2009-2017) were reviewed to identify patients with ccTGA who underwent anatomic repair or Fontan pathway.Pa-tient-and procedure-related variables were reviewed.Results We identified 37 patients.Group 1 consisted of 10 anatomic re-pairs, of which 4 required prior pulmonary artery banding.Median age at anatomic repair was 1.0 years( range: 0.3 -7.8 years).There was one early death, and one patients experienced ECMO support.The mean follow-up was(3.0 ±2.8)years (range:0.7-8.4 years).Five(55.5％) patients showed arrhythmias, and one required permanent pacemaker implantation during follow-up.Group 2(27 patients) underwent Fontan palliation, of which 23(85.2％) underwent prior bidirectional Glenn shunt.Median age at Fontan completion was 3.8years(range:2.2-14.3 years).there was one early death with a mor-tality of 3.7％.The mean follow-up was(2.8 ±1.6) years(range:0.8-8.2 years).There was 4(15.4％) cases of arrhyth-mias, but none required reintervention.The arrhythmias incidence in Fontan group was significantly lower than the anatomic re-pair group.The early-and mid-term survival rate were 90.0％ and 96.3％in the two groups.The difference was not statistical-ly significant(P=0.458).Conclusion Patients with ccTGA do well with both anatomic repair and the Fontan pathway in the medium term.Pulmonary artery banding can be used effectively for morphological left ventricular retraining , and extenuate tri-cuspid regurgitation.Excellent outcomes with reduced early complication and arrhythmias incidence can be achieved for this co-hort of patients when a strategy of avoiding complex anatomic repair in favor of the Fontan pathway is used .

Objective: To investigate the efficacy of multistage surgery in patients with functional single ventricle (FSV) and risk factors of postoperative death. Methods: The clinical data of all consecutive patients with FSV undergoing multistage single ventricle palliation surgery in Guangzhou women and children's medical center from January 2008 to December 2017 were retrospectively reviewed. The study included 289 patients. The age was 10.0 (6.0, 35.4) months,and there were 198 male and 91 female patients. The patients were followed up at outpatient clinic. Survival rates were calculated with Kaplan-Meier. Multivariate Cox regression analysis was made to determine the risk factors of postoperative death. Results: Seventy-nine patients required the first stage palliation surgery, 232 patients received the Glenn shunt surgery, and 162 patients completed the Fontan procedure. Overall, postoperative death occurred in 39 patients including 21 after the first stage palliation surgery (early stage 13 cases, late stage 8 cases) , 10 after the Glenn shunt surgery (early stage 5 cases, late stage 5 cases) , and 8 following the Fontan procedure (early stage 6 cases, late stage 2 cases) . Kaplan-Meier analysis showed that survival rate of the entire cohort was 90.2% (95%CI 86.7%-93.7%) , 85.9% (95%CI 81.8%-90.0%) ,and 84.6% (95%CI 79.7%-89.5%) at 1 year, 5 years and 10 years post operation. Survival rate was 74.4% (95%CI 64.8%-84.0%) , 73.0% (95%CI 63.2%-82.8%) , and 73.0% (95%CI 63.2%-82.8%) at 1 year, 5 years, and 10 years post the first stage palliation surgery, 97.8% (95%CI 95.8%-99.7%) , 95.2% (95%CI 92.3%-98.1%) , and 95.2% (95%CI 92.3%-98.1%) at 1 year, 5 years, and 10 years post Glenn shunt surgery, 95.6% (95%CI 92.5%-98.7%) and 93.7% (95%CI 88.8%-98.6%) at 1 year and 5 years post Fontan surgery. Multivariate Cox regression analysis revealed that total anomalous pulmonary venous connection (HR=5.47, 95%CI 2.71-11.04, P<0.001), atrioventricular valve regurgitation more than moderate (HR=2.52, 95%CI 1.32-4.79, P=0.005), systemic ventricular outflow tract obstruction (HR=3.47, 95%CI 1.30-9.29, P=0.013), and required the first palliation surgery (HR=3.12, 95%CI 1.59-6.15, P=0.001) were risk factors of postoperative death. Conclusions The multistage surgery can effectively improve the survival of patientswith functional single ventricle and is associated with satisfactory long-term prognosis. Total anomalous pulmonary venous connection, atrioventricular valve regurgitation more than moderate, systemic ventricular outflow tract obstruction, and required the first palliation surgery are risk factors of postoperative death in these patients.
