ObjectiveTo investigate the feasibility of video-assisted thoracoscopic surgery (VATS) lung resection in the treatment of tuberculosis.MethodsWe retrospectively analyzed the clinical data of 164 tuberculosis patients who underwent lung resection in Xi'an Chest Hospital from 2013 to 2017. Patients were divided into two groups according to the surgical procedure: a VATS group (85 patients, 56 males and29 females) and a thoracotomy group (79 patients, 52 males and 27 females). The clinical effect of the two groups was compared.Results Compared to the thoracotomy group, the VATS group had less operation time (151.59±76.75 min vs. 233.48±93.89 min, P<0.001), amount of intraoperative blood loss (200.00 ml vs. 600.00 ml, P<0.001), the postoperative drainage (575.00 ml vs. 1 110.00 ml, P=0.001), extubation time (4 d vs. 6 d, P<0.001) and hospital stay (13.00 d vs. 17.00 d, P<0.001). There was no statistical difference in postoperative complications (10 patients vs.17 patients, P=0.092) between the two groups. A total of 97 patients underwent lobectomy, including 36 of the VATS group and 61 of the thoracotomy group. The operation time (211.39±70.88 min vs. 258.20±87.16 min, P=0.008), the intraoperative blood loss (400.00 ml vs. 700 ml, P<0.010), the postoperative drainage (800.00 ml vs. 1 250.00 ml, P=0.001), extubation time (5.00 d vs. 8.00 d, P=0.002) and hospital stay (13.11±4.45 d vs. 19.46±7.74 d, P<0.010) in the VATS group were significantly better than those in the thoracotomy group. There was no statistical difference in postoperative complication rate (4 patients vs. 14 patients, P=0.147) between the two[1], groups.ConclusionCompared with conventional thoracotomy, VATS lung resection has obvious advantages in treatment of tuberculosis, which may be the preferred technique.
Objective To analyze the effect of monitoring and modulating the portal vein pressure and blood flow during living donor liver transplantation （LDLT） on preventing small-for-size-syndrome (SFSS). Methods Data of forty-four LDLT recipients between Oct.2007 and Oct.2008 were reviewed. Actual graft-to-recipient weight ratio（GRWR）, portal vein flow and pressure during operation and syndrome of SFSS after operation were recorded. The patients received splenectomy or splenic artery ligation according to actual GRWR, portal vein flow and pressure and WBC. Relationships between patients’ GRWR, portal vein flow, portal vein pressure and occurrence of SFSS were analyzed. Results Six patients received splenectomy and 7 patients received splenic artery ligation to decrease the portal vein flow and pressure during the operation. The portal vein flow and pressure decreased after splenectomy （Plt;0.05）. The portal vein pressure decreased （Plt;0.05） and the portal vein flow had no significant change after splenic artery ligation （P＞0.05）. No SFSS occurred after operation. Conclusion Modulation of portal vein flow and pressure by splenectomy or splenic artery ligation during LDLT operation can decrease the portal vein flow and pressure, and which can prevent the incidence of SFSS.
Objective To observe the recovery of recipients with complex portal vein thrombosis (CPVT) underwent “multiple to one” anastomosis and patency of portal vein blood flow during liver transplantation, and to ensure the reliability of this method. MethodsThe clinicopathologic data of the recipients with CPVT underwent “multiple to one” anastomosis in the Beijing Friendship Hospital, Capital Medical University were collected retrospectively. The “multiple to one” portal vein reconstruction was defined as the anastomosis of multiple vessels of portal venous system with the portal vein of graft, or the anastomosis that connected the blood vessel of portal venous system and the left renal vein/inferior vena cava to the portal vein of graft. ResultsA total of 5 patients were collected, including 1 patient with Yerdel grade 3 thrombosis and 4 patients with Yerdel grade 4 thrombosis. In 3 cases, the left renal vein, inferior vena cava, left renal vein were combined with the parabiliary vein, respectively, in the anastomosis to the donor portal vein. In another 2 cases, portal vein and left renal vein were combined with gastric coronary vein, respectively, in the anastomosis to the donor portal vein. During the follow-up period of 162–865 d, all patients had the stable portal vein blood flow without any symptom of portal hypertension. One patient had thrombosis at the anastomosis with varicose vein, while the anastomosis with left renal vein was unobstructed, which did not affect the donor liver function. ConclusionMultiple blood supply of portal vein is established after “multiple to one” anastomosis, and stability of portal vein blood flow can be maintained after a blood redistribution of portal venous system following liver transplantation.
ObjectiveTo systematically review the associations of cognitive frailty with mortality and hospitalization in the elderly. MethodsThe VIP, PubMed, CNKI, WanFang Data, CBM, Embase, Cochrane Library and Web of Science databases were electronically searched to collect cohort studies on the association of cognitive frailty with mortality or hospitalization in the elderly from inception to May, 2023. Two reviewers independently screened the literature, extracted data and assessed risk of bias of the included studies. Meta-analysis was performed by R 4.2.2 software. ResultsA total of 19 cohort studies involving 63 624 elderly were included. The results of meta-analysis showed that compared with healthy elder, the elder with cognitive frailty had a higher mortality (OR=2.75, 95%CI 2.10 to 3.59, P<0.01) and hospitalization (OR=1.67, 95%CI 1.40 to 2.00, P<0.01). Subgroup analysis showed that cognitive frailty was related to the risk of death in different status of frailty and cognitive function, different assessment tools, different countries of development, different follow-up time and research sites. At the same time, different status of frailty and cognitive function and different levels of development of countries were related to the risk of hospitalization. ConclusionCurrent evidence shows that cognitive frailty can increase the risk of hospitalization and mortality in the elderly. It is suggested that early screening and intervention of cognitive frailty should be carried out to effectively reduce the risk of adverse consequences, so as to achieve healthy aging.
Objective To explore the correlation between physical activity, sleep and aging using a two-sample Mendelian randomization (MR) method. Methods The data through genome-wide association studies was summarized. The single nucleotide polymorphisms (SNPs) related to physical activity and sleep as instrumental variables was selected. The inverse variance weighting method was used for the main analyses, complemented by the weighted median method and MR Egger regression, and then sensitivity analyses were carried out in terms of multiplicity, heterogeneity and leave-one-out method. Finally, multivariate Mendelian methods were applied to eliminate confounders and find mediators. Results A total of two types of physical activity (strong physical activity, physical inactivity) and three sleep conditions (daytime naps, short sleep duration, adequate sleep duration) were found to have a causal relationship with frailty index (P<0.05), while physical inactivity was found to have a causal relationship with telomere length (P<0.05). A total of 167 SNPs were included in the analysis. Strong physical activity [correlation coefficient (β)=−1.26, 95% confidence interval (CI) (−1.60, −0.96), P<0.0001], adequate sleep duration [β=−0.17, 95%CI (−0.26, −0.09), P<0.001] were negatively correlated with the frailty index. Physical inactivity [β=1.47, 95%CI (0.85, 2.08), P<0.001], daytime naps [β=0.25, 95%CI (0.12, 0.39), P=0.0002], and short sleep duration [β=0.20, 95%CI (0.13, 0.27), P<0.0001] were positively associated with frailty index. Physical inactivity [β=−0.38, 95%CI (−0.69, −0.07), P=0.02] was negatively correlated with telomere length. Percentage body fat, body fat mass, waist circumference, body weight and body mass index partially mediated 25.52%, 23.52%, 10.08%, 17.6% and 10.08% of the effect between daytime naps and frailty index, respectively. Conclusion There is a causal relationship between physical activity, sleep, and aging.
Objective To evaluate and summarize the relevant evidence of oxygenation strategies with tracheal intubation after extubation for adult in intensive care unit (ICU), and to provide evidence-based practice for the development of scientific and effective strategies tracheal intubation after extubation for ICU adult patients. Methods Evidence-based databases, related guideline websites, association websites and original databases were searched by computer for literature about oxygenation strategies with tracheal intubation after extubation for ICU adults patients was extracted. The retrieval time was from the establishment of the databases to May 2023. Two researchers trained in evidence-based practice evaluated the quality of the included literature and extracted evidence from the literature that met the quality evaluation criteria. Results A total of 18 articles were included, including 7 guidelines, 4 clinical decisions, 2 expert consensus, 4 systematic reviews and 1 randomized controlled trial. A total of 22 pieces of best evidence were formed, including 7 aspects of basic principles, evaluation, selection, parameter setting, withdrawal, effect evaluation and precautions. ConclusionThe medical staff should select the best evidence based on the actual clinical situation and the patient’s own needs, and adjust the oxygenation strategies to reduce the rate of tracheal intubation and improve the prognosis of patients.
Objective To discuss the criteria of recipient selection，surgical approach，and complications and its theray by using of pediatric donation after cardiac death liver graft in adult recipient. Methods The clinical data of one case of pediatric donation after cardiac death liver to adult recipient was analyzed retrospectively and the literatures were reviewed. Results A 6-year-old girl pronounced brain death due to drowning and on the basis of cardiopulmonary criteria donated the organ．The liver graft weight was 598 g and the warm ischemic time was 10 min. The liver donor was transplanted to a 64-year-old woman，the graft to recipient weight ratio was 1.09%，the graft volume/estimated standard liver volume was 61.8%．The classic orthotopic liver transplantation without bypass was underwent，the postoperative recovery was smooth after the liver transplantation．The CT scan showed that the liver graft volume was 1 003cm3 on day 14 after operation．The patient was discharged on 45 d after orthotopic liver transplantation and the liver function was normal when followed-up 3 months after the operation. Conclusions Pediatric donation after cardiac death liver graft can be successfully utilized to adult recipient．Recipient selection and surgical approach should be decided by conditions of both donor and graft．
Objective To report our experience in living donor liver harvesting of right lobe grafts. MethodsThe data of 76 living donors of right lobe grafts hepatectomy between August 2007 and December 2008 were studied. Before operation, the graft size, remnant liver volume rate, fatty liver, middle hepatic vein type, and the level of portal hypertension of recipient were comprehensive assessed to determine whether harvested middle hepatic vein. The graft was harvested depending on the port vein and hepatic artery ischemia-line. B-ultrasound was used to definite the structure and branch of middle hepatic vein, and intraoperative cholangiography was performed to definite the structure and variation of bile duct. Donor operative time, intraoperative blood loss, postoperative hospital stay, levels of bilirubin, international normalized ratio （INR）, and ALT, and complications after operation were recorded. Results All the operations were successful. The operative time was (8.3±1.3) h, the blood loss was (325±127) ml without blood transfusion in operation. The ALT, INR, and bilirubin recovered on the 12th day. The most common complication in early post-operation was wound infection in 5 cases, 4 cases had cholestasis, 4 cases occurred cross-section bile leakage, and 11 cases occurred varying degrees of delayed gastric emptying in 4～7 d after operation, who were all alleviated by corresponding treatments. The hospital stay was 9～21 d (median: 14 d) after operation. Conclusion Preoperative evaluation of the hepatic anatomy and precise surgical procedure are crucial, which will help the development of graft harvesting and rehabilitation of donor.
ObjectiveTo observe the clinical effect of Rituximab combined with intravenous immunoglobulin (IVIG) in preventing blood group antibody mediated rejection (AMR) in pediatric ABO incompatible living donor liver transplantation (ABOi-LDLT).MethodsA total of 503 cases of pediatric living donor liver transplantation in Beijing Friendship Hospital Affiliated to Capital Medical University from June 2013 to December 2020 were retrospectively collected; the overall survival of recipient and graft were compared between ABOi-LDLT and ABO compatible living donor liver transplantation (ABOc-LDLT), and we summarized the data of AMR in 7 cases received Rituximab+IVIG protocol.ResultsThere were 53 cases of ABOi-LDLT and 450 cases of ABOc-LDLT in our study. The 5-year cumulative survival rate of recipients and grafts was 98.0% and 96.0% in the ABOi-LDLT group respectively, and in ABOc-LDLT group was 92.2% and 89.1% respectively, there was no significant difference between the two groups (P=0.232, P=0.381）. Seven children with blood group antibody titer >1∶64 were included in the study. On the basis of classical intensive immunosuppressive therapy, all patients were treated with Rituximab+IVIG. The blood group antibody titer of 6 patients remained stable, and no rejection occurred; one patient developed severe AMR and graft failure, and recovered after salvage treatment of ABOc-LDLT.ConclusionRituximab+IVIG can be used as an effective therapeutic option to prevent blood group AMR after ABOi-LDLT.
ObjectiveTo investigate the effect of perioperative intravenous immunoglobulin (IVIG) on the reduction of blood group antibody titer and prognosis in children with ABO incompatible (ABO-I) liver transplantation.MethodsA retrospective study was conducted in 20 children undergoing ABO-I liver transplantation in Beijing Friendship Hospital Affiliated to Capital Medical University from July 2017 to March 2020. The changes of blood group antibody titer, alanine aminotransferase, and total bilirubin before and after operation, as well as survival rate were analyzed after intravenous IVIG during perioperative period.ResultsAfter ABO-I liver transplantation, the 1-year survival rate of 20 patients was 100%, and 1 case (5%) developed immune rejection. Compared with before operation, on the day of operation, IgM blood group antibody titer did not change in 4 cases (20%), increased in 1 case (5%), and decreased in 15 cases (75%); in one week after operation: 12 cases (60%) decreased, 5 cases (25%) increased, and 3 cases (15%) remained unchanged; in one month after operation: 18 cases (90%) decreased , 2 cases (10%) remained unchanged. Compared with before operation, the titer of IgG blood group antibody increased in 2 cases (10%), remained unchanged in 6 cases (30%), and decreased in 12 cases (60%); in one week after operation: 4 cases (20%) increased, 4 cases (20%) remained unchanged, and 12 cases (60%) decreased; in one month after operation: 3 cases (15%) increased, 4 cases (20%) remained unchanged, and 13 cases (65%) decreased. The levels of alanine aminotransferase and total bilirubin in 1 month after operation were lower than those on the day of operation.ConclusionThe effect of IVIG on reducing blood group antibody titer in children after ABO-I liver transplantation is not obvious, and its actual clinical effect needs to befurther confirmed.
