ObjectiveTo systematically review studies investigating the rate of falls among Chinese elderly. MethodsThe CNKI, VIP, CBM, WanFang Data, EMbase, The Cochrane Library and PubMed databases were electronically searched to identify cross-sectional studies on the rate of falls in Chinese elderly published from January 1st, 2000 to December 31st, 2021. Two reviewers independently screened the literature, extracted data, and assessed the risk of bias of the included studies. Meta-analysis was then performed using Stata 16.0 software. Results A total of 54 cross-sectional studies, involving 111 098 cases were included. The results of meta-analysis showed that the rate of falls among Chinese elderly was 19.3% (95%CI 16.9% to 21.6%). Subgroup analyses showed that the fall rates were 16.1% and 21.9% for males and females, respectively. The rates for 60-69, 70-79, and >80 years age groups were 16.3%, 21.7%, and 27.3%, respectively. The rates for the North, South, East, Southwest, and Central parts of China were 16.6%, 17.9%, 18.7%, 22.0%, and 25.8%, respectively. For the urban and rural elderly, the rates were 16.4% and 23.1%, respectively. The rates for those with or without spouses were 24.2% and 26.8%, respectively, while for the solitary and non-solitary elderly were 21.1% and 17.8%, respectively. The rates for elderly with or without exercise habits were 22.1% and 27.1%, respectively. ConclusionThe rate of falls is high among Chinese elderly, especially among females, older individuals, those in Southwest China, rural individuals, those without spouse, solitary individuals and those without exercise habits.
ObjectiveTo explore the relationship between platelet and prognosis of the total correction of tetralogy of Fallot (TOF).
MethodsWe included 11 dead patients with TOF at age of 0-6 years as a death group between 2011 and 2014 year. There were 7 male and 4 female patients at age of 18.6±16.4 months in the death group. We selected 11 matched survival patients according to age, gender of the patients as a survival group. There were also 7 male and 4 female patients at age of 19.4±16.7 months in the death group. The patients were divided into a high-platelet group and a low-platelet group. There were 6 male and 5 female patients in the high-platelet group. While there were 8 male and 3 female patients in the low-platelet group. Inflammatory cytokine and mortality were compared between the two groups.
ResultsPost-operative count of platelet in the death group was significantly lower than that in the live group, while post-operative interleukin-6 (IL-6) and C reactive protein (CRP) were much higher than those in the death group (P<0.05). Mortality was higher in the low-platelet group than that in the high-platelet group (P<0.05).
ConclusionPlatelets may alleviate inflammatory response and reduce mortality, which played a great role of protection.
Abstract: Objective To evaluate the protective effects of Ulinastatin on the peri-operative liver and renal function in patients undergoing cardiac surgery for tetralogy of Fallot (TO F). Methods Thirty-eight patients with TOF were divided into Ulinastatin group and control group according to admission sequence, 19 cases in each group.For Ulinastatin group, intravenous Ulinastatin was given with a dosage of 10 000U /kg at 1h before operation, 1h and 24 h after operation. For control group, no Ulinastatin was given. 10 ml fresh urine and 2 ml blood samples were collected before operation, and postoperative 1h, 10h, 24h, 48h and 72h, respect ively. The liver and renal functions were measured. Fluid intake, urine output, chest drainage, dosage of furosemide, durations of mechanical ventilation and intensive care unit ( ICU ) stay were recorded. Results Neither arrhythmia nor low cardiac output syndrome occurred for both groups. No peri-operative death. Compared with control group, dose of furosemide, period of mechanical ventilation were lower, while urine output was higher in Ulinastat in group; the aberrant climax value of urine pro tein and N-acetylglucosam inidase (NAG) were lower in Ulinastatin group (10h post-operat ively, urinem icroalbum in: 65. 2 ± 58. 3mg/L vs. 71. 8 ±58. 9mg/L ; urine transferrin: 5. 8 ± 3. 6mg/L vs. 7. 4 ± 5. 4mg/L ; urine immunoglobulin G: 26. 9±20. 3mg/L vs. 31. 3±23. 3mg/L ; 1h post-operat ively; urine NAG: 61. 4±81. 6U /L vs. 76.1±48. 5 U /L ; P lt; 0. 05) and maintained in shorter period (P lt; 0. 05) , it returned to baseline value at 48h and 72 h post-operatively. The value of alanine aminotransferase (ALT) significantly increased post-operatively at every time points in control group (P lt; 0. 01) , w hile no obvious change in Ulinastat in group (P gt; 0. 05). The increased value of aspartate aminotransferase (AST ) in Ulinastatin group was significantly lower than that in control group (10h post-operat ively: 144. 4±20. 8U /L vs. 202. 7±74. 1U /L ; P lt; 0. 01). The value of AST returned to baseline value at 48h and 72h post-operat ively. Conclusion U linastatin is an effect ive strategy for protecting peri-operat ive liver and renal function of the patients with tetralogy of Fallot and the clinical application of Ulinastatin is safe and effective.
ObjectiveTo investigate if the ratio of pulmonary valve annulus, which is the proportion of pulmonary valvular annulus size to total size of aortic valvular annulus and pulmonary valvular annulus, can better guide the choice of surgical approach than the value of z.MethodsA retrospective analysis was made for 254 patients who underwent total correction of tetralogy of Fallot in Guangdong General Hospital between January 2016 and January 2018. There were 154 males and 100 females with an average age of 14.60±18.76 years. The patients were categorized into two groups, a transannular patch group (TAP, n=164) and a non-TAP group (n=90). The sizes of pulmonary and aortic valvular annulus were evaluated in each group, and the cutoff value of proportion of pulmonary valvular annulus for TAP was calculated.ResultsBoth proportion of pulmonary valvular annulus and z-scores were smaller in the TAP group than those in the non-TAP group (0.29±0.06 vs. 0.36±0.06, P<0.001; –4.04±2.13 vs. –2.06±1.84, P<0.001, respectively). In receiver operating characteristics analyses, proportion of pulmonary valvular annulus and the z-score cutoff values were 0.353 (area under the curve 0.781, 95%CI 0.725–0.831) and –2.13 (area under the curve 0.766, 95%CI 0.709–0.817), respectively, demonstrating that the proportion of pulmonary valvular annulus was a more powerful diagnostic tool as a predictor of TAP.ConclusionOur results suggest that the proportion of pulmonary valvular annulus is an effective predictor for TAP and can be easily applied to clinical practice.
Objective To evaluate early results of valved bovine jugular vein patch for reconstruction of the right ventricular outflow tract （RVOT）.?Methods From May 2009 to March 2010， a total of 60 patients with complex congenital heart diseases underwent reconstruction of RVOT with valved bovine jugular vein patch in Wuhan Asia Heart Hospital. There were 42 males and 18 females with their mean age of 6.2±8.9 years （ranging from 5 months to 33 years） and mean body weight of 27.5±24.0 kg， and 34 patients were less than 1 year. Preoperative clinical diagnosis included tetralogy of Fallot （n=38） and double outlet of right ventricle with pulmonary stenosis （n=22）. All the patients underwent one-stage surgical repair. Before operation， 4 patients underwent catheter intervention for their major aortopulmonary collaterals. The diameters of pulmonary arterial ring of all the patients were 2 standard deviation less than normal range， and trans-annular patch was chosen for RVOT reconstruction. All the patients were postoperatively followed up for 18 to 26 months （mean 21.2±4.6 months）.?Results There was no in-hospital death. And no second surgical intervention was needed for conspicuous RVOT stenosis or pulmonary regurgitation. Three patients needed reintubation for lung edema after extubation as a result of major aortopulmonary collaterals. Four patients underwent reexploration for postoperative bleeding. And all the other patients were discharged uneventfully. Mean cardiopulmonary bypass time was 84.0±22.0 min， and mean aortic cross-clamping time was 42.0±12.0 min. Mean RVOT gradient right after surgery was 18.0±4.5 mm Hg， which was not statistically different from mean RVOT gradient of 19.2±5.4 mm Hg measured by transthoracic echocardiography at their last postoperative follow-up（P＞0.05）. The degree of pulmonary regurgitation right after surgery was trivial in 32 patients（1＋）， mild in 28 patients（2＋）， which were not statistically different from the degree of pulmonary regurgitation at their last postoperative follow-up: trivial in 28 patients （1＋）， mild in 27 patients（2＋）， and moderate in 5 patients（3＋）. Calcification was not observed on the valved bovine jugular vein patch and valve cusp， and the valve cusp motioned well. No thrombosis or endocarditis was observed on the valved bovine jugular vein.?Conclusions For patients with tetralogy of Fallot or double outlet of right ventricle （DORV） and pulmonary stenosis， valved bovine jugular vein patch is a good choice for trans-annular reconstruction of RVOT. There is no severe postoperative complication related to bovine jugular vein， the RVOT pressure gradient does not increase significantly， and anti-regurgitation result is satisfactory in short-term follow-up. Further follow-up is required to evaluate its long-term outcome.
ObjectiveIn order to correct left pulmonary artery (LPA) stenosis in tetralogy of Fallot (TOF), a technique for LPA reconstruction by widening pulmonary arterial posterior wall was devised. To evaluate its surgical technique as well as postoperative outcome.
MethodsFrom January 2008 through August 2014 year, 1 142 consecutive patients underwent repair of TOF including 44 patients with TOF and LPA stenosis in our hospital. We used widening pulmonary arterial posterior wall for LPA reconstruction in 21 patients. The median age was 22.8 months (range, 1 month to 11 years), and the median weight was 9.1 kg (range, 3.8-29 kg).
ResultsThere was one operative death. No death occurred during the follow-up period in the other 20 patients. There were 4 patients with complicate unbalanced pulmonary perfusion postoperatively. Echocardiography at 3-72 months follow-up demonstrated no obvious stenosis was found at LPA in 14 patients, and mild stenosis (32.8±12.7 mm Hg) in 6 patients. Only 1 patient required further interventions because of restenosis of LPA.
ConclusionsLPA reconstruction by widening pulmonary arterial posterior wall is an effective method in the management of stenosis of LPA in the patients with TOF. We emphasize division of the arterial duct or ligamentum completely because it will tether and kink the LPA. This procedure retains the better growth potential by increasing autogenous tissue of native tissue.
Objective To compare the difference of effect while using homograft pericardium patch and Gore- tex patch in staged repair of tetralogy of Fallot（TOF） to enlarge the right ventricular outflow tract （RVOT）. Methods Twenty-eight patients with TOF who underwent the staged complete repair were divided into 2 groups according to the date of surgery. Gore-rex group, 13 cases, their RVOT were enlarged with Gore-tex patches. Cryopreserved homograft pericardium patch group, 15 cases, their RVOT were enlarged with cryopreserved homograft pericardium patches. Clinical results and follow-up results were compared. Results There were 1 operative death in Gore-tex patch group （7. 7%）, and 1 early postoperative death in cryopreserved homograft pericardium patch group （6. 7%）. Hemostasia time, the pericardial cavity drainage volume in cryopreserved homograft pericardium patch group were less than those in Gore-tex patch group （P〈0. 01）. All patients were followed-up for 0.8-4.5years. The residual obstruction rate at RVOT level in Gore-tex patch group was higher than that in cryopreserved homograft pericardium patch group by echocardiography （P〈0.01）. No calcification shadow was found on the chest X-ray. Conclusion Homograft pericardium is the tissue with high density and intensity, its elasticity and compliance are good. Using homograft pericardium patch may be helpful to decrease the residual obstruction of RVOT after operation. It can be adapted as a repairing material in heart surgery.
The aim of this study was to clarify characteristics of cardiovascular malformation in patients associated with tetralogy of Fallot (TOF) by using dual-source computed tomography (DSCT) angiography. We retrospectively analyzed DSCT angiography of 99 consecutive patients with TOF. In addition to typical CT features of TOF in all patients, the DSCT angiography showed 27 cases (27.27%) of atrial septal defect, 14 cases (14.14%) of patents ductus arteriosus, 11 cases (11.11%) of bicuspid pulmonary valve, 18 cases (18.18%) of congenital coronary artery malformation, 22 cases (22.22%) of right aortic arch, 12 cases (12.12%) of persistent left superior vena cava, 8 cases (8.08%) of retro-aortic innominate vein and 9 cases (9.09%) of pulmonary venous anomalous. DSCT is capable of displaying anatomical characteristics of cardiovascular malformation in patients with TOF.
Objective To improve the operative effects of patients who had tetralogy of Fallot with aortopulmonary collateral arteries (TOF-APCAs) and evaluate the clinical effects of staging and onestop hybrid approach for TOFAPCAs. Methods From January 2003 to December 2007, thirty patients with TOF-APCAs had undergone combined therapy of APCAs embolization and complete surgical repair. Fifteen patients had APCAs embolization therapy before or after TOF radical operation(staging hybrid group ); Fifteen had onestop hybrid treatment(onestop hybrid group). Results Angiography revealed that there were 19 APCAs in staging hybrid group, and of which 15(78％) were embolized successfully. Five cases had complications and one died from respiratory circulating failure. The rest all recovered and discharged. And 22 APCAs were found in one-stop hybrid group, eighteen (82％) of them were embolized successfully. Only one case had pulmonary effusion. The time of hospitalization(median 37 d vs. 22 d, P=0.011),ICU staying（median 7.0 d vs. 4.7 d,P=0.029）and endotracheal intubation（median 131 h vs. 19 h,P=0.009） was obviously longer, and the hospitalization expenses（median 64 101 [CM(159mm]yuan vs. 48 021 yuan, P=0.033）were obviously higher in staging hybrid group than that in one-stop hybrid group.And there was no statistical significance in cardiopulmonary bypass time（P=0.126） and aortic clamping time（P=0.174） between two groups. Conclusion In comparison with traditional staging hybrid approach, one-stop hybrid approach can simplify the operative process for patients who have TOFAPCAs, improve the operative successful rate and cut down expenses.
Objective To investigate the optimal timing for surgical treatment of infants less than six months of age with tetralogy of Fallot (TOF), and to improve surgical results and reduce early mortality. Methods Clinical material of 108 consecutive patients with TOF who were less than six months of age undergoing early surgery from Oct.1996 to Dec. 2006 were retrospectively reviewed. There were 70 males and females with mean age of 4.70 months (9 d-6 months). 104 patients underwent complete repair and four patients underwent BlalockTaussig (B T) shunt. Emergency procedures have been performed in 5 patients. Results Five patients (4.63%) died of low cardiac output syndrome (3 patients), pulmonary infection and acute respiratory distress syndrome (1 patient), and acute necrotizing enteritis (1 patient).82 patients were followed up, followup period was 31.17±40.00 months.21 patients lost to followup. One patient(0.92%) required additional intervention for pulmonary valve stenosis 6 months after operation. Heart functional class(New York Heart Association) recovered toⅠ-Ⅱgrading in other patients. Echocardiography shows: no residual ventricular shunt, no stenosis in right ventricular outflow tract and pulmonary valve, pressure difference≤50 mm Hg. No late deaths. Conclusion Early definitive repair of TOF can be performed safely on infants less than six months of age, the results of low mortality is acceptable.
