RESUMO
Objective: To evaluate the mid-term efficacy of ABO incompatible living donor kidney transplantation (ABOi-KT) based on the results of routine renal biopsy for transplantation. Methods: Retrospective collection of clinical data from 23 pairs of ABOi-KT donors and recipients at the First Affiliated Hospital of Sun Yat-sen University from July 2015 to November 2021. ABOi-KT was performed on recipients after desensitization treatment, and the results of routine kidney transplant biopsy at 1 week, 1 month, 3 months, 6 months, and 12 months after surgery were analyzed. Combined with blood type antibody levels and renal function recovery, the mid-term efficacy of ABOi-KT was evaluated. Results: Among the 23 recipients, there were 19 males and 4 females; age range from 19 to 47 years old [(29.6±6.7) years old], all underwent ABOi-KT successfully after receiving desensitization treatment. The follow-up time was (44.6±22.4) months, of which 22 cases were followed up for more than 1 year. The incidence rates of rejection reactions at 1 week, 1 month, 3 months, 6 months, and 12 months after surgery were 15.0% (3/20), 11.1% (1/9), 7.7% (1/13), 25.0% (3/12), and 12.5% (1/8), respectively. For receptors with rejection reactions, targeted anti-rejection therapy was performed based on clinical symptoms and various indicators. Borderline T cell mediated rejection (TCMR) can be converted to mild tubular inflammation after anti-rejection treatment. The positive rate of complement C4d in peritubular capillaries was 95.0% (19/20) one week after surgery, and the positive rate of complement C4d was 100% at 3 and 12 months after surgery. The cumulative survival rates at 1, 3, 5, and 7 years after surgery were all 100%. The cumulative survival rates at 1, 3, 5, and 7 years after kidney transplantation were 100%, 93.3%, 84.0%, and 84.0%, respectively. Except for 2 recipients who underwent transplantation in 2017 and experienced kidney failure at 30 and 49 months after surgery, all other transplanted kidneys survived. Conclusions: The results of routine renal transplant biopsy show that ABOi-KT has a good mid-term therapeutic effect. The pathological changes of ABOi-KT can be dynamically observed through routine renal transplant biopsy and targeted treatment for rejection reactions can be provided accordingly.

Objectives: This study sought to describe our institutional experience of repeated percutaneous stellate ganglion blockade (R-SGB) as a treatment option for drug-refractory electrical storm in patients with nonischemic cardiomyopathy (NICM). Methods: This prospective observational study included 8 consecutive NICM patients who had drug-refractory electrical storm and underwent R-SGB between June 1, 2021 and January 31, 2022. Lidocaine (5 ml, 1%) was injected in the vicinity of the left stellate ganglion under the guidance of ultrasound, once per day for 7 days. Data including clinical characteristics, immediate and long-term outcomes, and procedure related complications were collected. Results: The mean age was (51.5±13.6) years. All patients were male. 5 patients were diagnosed as dilated cardiomyopathy, 2 patients as arrhythmogenic right ventricular cardiomyopathy and 1 patient as hypertrophic cardiomyopathy. The left ventricular ejection fraction was 37.8%±6.6%. After the treatment of R-SGB, 6 (75%) patients were free of electrical storm. 24 hours Holter monitoring showed significant reduction in ventricular tachycardia (VT) episodes from 43.0 (13.3, 276.3) to 1.0 (0.3, 34.0) on the first day following R-SGB (P<0.05) and 0.5 (0.0, 19.3) after whole R-SGB process (P<0.05). There were no procedure-related major complications. The mean follow-up was (4.8±1.1) months, and the median time of recurrent VT was 2 months. Conclusion: Minimally invasive R-SGB is a safe and effective method to treat electrical storm in patients with NICM.

AIM: To investigate the performance of multi-parameter coronary computed tomography angiography (CCTA), including stenosis, plaque qualitative-quantitative characteristics, and fractional flow reserve derived from CCTA (FFRct), to predict acute myocardial infarction (AMI) and build a combined model. MATERIALS AND METHODS: Thirty patients with AMI 90 days after CCTA and 120 matched patients without AMI were enrolled retrospectively. Multiple CCTA parameters were analysed and compared. Independent risk factors were obtained through univariate and multivariate regression analyses, after which a multi-parameter model was built. RESULTS: A total of 150 patients were analysed successfully. The multi-parameter CCTA model (area under the curve, 0.944; p<0.001) had a higher predictive value than each single parameter (p<0.001, all). Independent risk factors were intra-plaque dye penetration (IDP; odds ratio [OR], 8.373; p=0.002), lipid plaque volume (LPV; OR, 1.263; p<0.001), and FFRct ≤0.83 (OR, 8.092; p=0.001). CONCLUSION: This one-stop multi-parameter CCTA model, comprising IDP, LPV, and FFRct as independent risk factors, has good performance to predict AMI.

Objective: To investigate the acute and long-term outcome of catheter ablation for the treatment of ventricular tachycardia (VT) in patients with arrhythmogenic left ventricular cardiomyopathy (ALVC). Methods: This retrospective, cross-sectional study enrolled ALVC patients undergoing radiofrequency ablation for the treatment of VT at the First Affiliated Hospital of Nanjing Medical University from January 2011 to December 2018 and collected their clinical characteristics and intraoperative electrophysiological examination. Patients were followed up every 6 months after radiofrequency ablation until August 2021. Echocardiographic results and VT recurrence post radiofrequency ablation were analysed. Results: Totally 12 patients were enrolled (mean age: (42±15) years, 11 males(11/12)). The mean of left ventricular end diastolic diameter (LVDd) and left ventricular ejection fraction (LVEF) were (51±5)mm and (65±5)%, respectively. Twelve VTs were induced in 10 patients during the electrophysiological study, and the mean tachycardia cycle length was (293±65) ms. Three-dimensional substrate mapping revealed the diseased area at endocardial site in one patient, at epicardial sites in the other 11 patients (involved endocardial sites in 2 cases) with the basal part near the mitral annulus being the predilection for the substrate (10/11). After the catheter ablation at the endocardial and epicardial sites respectively, the complete procedure endpoint was achieved in all patients (VT cannot be induced post ablation). The median follow-up time was 65 (25, 123) months. One patient was lost to follow-up, and the other 11 patients survived without VT. No significant cardiac function deterioration was detected by the echocardiographic examination ((51±5)mm vs. (52±5)mm, P>0.05 for LVDd, (65±5)% vs. (60±6)%, P>0.05 for LVEF) at the end of follow-up. Conclusion: After radiofrequency ablation, the complete procedure endpoint is achieved in ALVC patients, and the catheter ablation provides long-term ventricular tachycardia control during the long-term follow-up.

Objective: To compare trends in congenital heart disease (CHD) mortality between China and North America from 1990 to 2017. Methods: Using the data from the Global Burden Of Disease (GBD) study 2017, we analyzed the related indicators of CHD mortality in China and North America from 1990 to 2017, including standardized mortality, number of deaths, age distribution of death population and age-specific mortality of CHD in each birth cohort. Age-period-cohort model was used to calculate the annual percent change of age-standardized and age-specific mortality rates of CHD (% per year), period effect-adjusted age-specific mortality rates, and the relative risk of death among CHD population at different time periods (2000ï¼2004 as reference period) and different birth cohorts (1970 as reference cohort). Results: In 2017, the age-standardized mortality rates for CHD in China and North America were 2.63/100 000 and 1.13/100 000 respectively, a decrease of 50.4% and 49.4% compared to 1990. Of all deaths from CHD in China, 76.8% were found in children under 5 years, which was higher than that in North America (51.7%). For population under 40 years, the period effect-adjusted age-specific mortality was higher in China (0.46-167.94 per 100 000 person-years) than in North America (0.68-22.47 per 100 000 person-years); whereas for population over 40 years, mortality was lower in China (0.13-0.34/100 000 person years) than in North America (0.43-0.72/100 000 person-years).From 1990 to 2017, CHD mortality in China decreased by 1.95% per year. The annual decrease of mortality ranged from 1.95% to 3.64% per year in population under 45 years, but the mortality showed increasing trends among those over 50 years. In 2015ï¼2019, the relative risk of death from CHD decreased by 31% in China and 24% in North America. For 2015 birth cohort, the relative risk of death decreased by 84% in China and by 64% in North America. Conclusions: In the past 30 years, the risk of death from CHD in China has significantly decreased, and the survival gap with North America is dramatically narrowed. However, mortality is higher among younger populations in China than in North America, and the mortality in the elders shows increasing trends each year in China.
RESUMO
AIM: To investigate the value of myocardial computed tomography (CT) perfusion imaging (CTP) and atherosclerotic plaque characteristics (APCs) identified on coronary CT angiography (CCTA) for the detection of myocardial ischaemia by using single-photon-emission CT (SPECT) as a reference. MATERIALS AND METHODS: Thirty-six patients (63.9% males) undergoing combined stress dynamic CTP and CCTA were enrolled and analysed. Myocardial blood flow (MBF) from CTP was quantified and compared between normal and abnormal segments. The ability of CTP and APCs to detect ischaemia was compared to that of SPECT. RESULTS: Nineteen patients with 78 segments had perfusion abnormalities on CTP. A significant difference was seen in MBF values between normal (118.51±27.86 ml/100 ml/min) and hypoperfused (79.60±21.35 ml/100 ml/min) segments (t=15.832, p<0.05). The sensitivity and specificity for identifying ischaemia were 90.91% and 94.97%, respectively, on a per-segment basis, resulting in a r value of 0.737 (p<0.05). On a per-vessel basis, the sensitivity and specificity for detecting ischaemia were 86.67% and 84.62%, respectively, for CTP; 93.33% and 58.97%, respectively, for CCTA; and 86.67% and 87.18%, respectively, for CTP combined with CTA, with an area under the receiver-operator characteristic curve (AUC) being 0.87 (p<0.05) and 0.887 (p<0.05) for CTP and its combination with CTA, respectively. On CCTA, 55 vessels with APCs were detected, with an AUC of 0.737 (p<0.05) for APCs combined with CCTA stenosis and 0.802 (p<0.05) for APCs combined with CTP. CONCLUSIONS: Dynamic stress CTP shows good correlation with SPECT for the detection of ischaemia. Additionally, combining APCs with CCTA stenosis has the ability to discriminate ischaemic stenosis.

BACKGROUND AND OBJECTIVE: The specific pathogenesis of generalized aggressive periodontitis (GAgP) has not yet been clarified, and few studies have focused on the association between GAgP and metabolomics. To elucidate the roles of metabolic profiles in the status of GAgP, this study aimed to identify the differential metabolic profiles between patients with GAgP and healthy controls using an untargeted metabolomic profiling method. MATERIAL AND METHODS: Serum and gingival crevicular fluid samples were collected from healthy controls (n = 20) and patients with GAgP (n = 20) in this cross-sectional study. The relative levels of biomarkers in the samples were measured by gas chromatography-mass spectrometry. Principal components analysis and orthogonal partial least-squares discriminant analysis were used for statistical analysis. Metabolites were analysed qualitatively using the FiehnLib and NIST databases. Full-mouth probing depth and clinical attachment loss were recorded as indexes of periodontal disease. RESULTS: A total of 349 metabolites were qualitatively detected in the gingival crevicular fluid samples, and 200 metabolites were detected in the serum samples. Compared with healthy controls, patients with GAgP showed significant increases in serum urea and allo-inositol levels. In contrast, glutathione, 2,5-dihydroxybenzaldehyde, adipic acid and 2-deoxyguanosine levels were decreased in patients with GAgP. In the gingival crevicular fluid samples, noradrenaline, uridine, α-tocopherol, dehydroascorbic acid, xanthine, galactose, glucose-1-phosphate and ribulose-5-phosphate levels were increased in patients with GAgP, while thymidine, glutathione and ribose-5-phosphate levels were decreased. CONCLUSION: The metabolomics analysis by gas chromatography-mass spectrometry is an effective and minimally non-invasive way to differentiate the metabolites characteristic of patients with GAgP. Both serum and gingival crevicular fluid metabolomics are significantly different between patients with GAgP and healthy controls. These metabolic profiles have great potential in detecting GAgP and helping to understand its underlying mechanisms.

The aim of this study was to evaluate the clinical outcomes of patients with posteromedial tibial plateau fractures treated by open reduction and internal fixation (ORIF) through a posteromedial approach. Thirty-six patients with posteromedial tibial plateau fracture underwent ORIF through a posteromedial approach and were retrospectively analyzed. Pre-operative X-ray pictures and CT images were -obtained. And there were 11 cases of posteromedial tibial plateau fracture and 25 cases of posteromedial and posterolateral tibial plateau fracture. All the -patients were treated surgically with posteromedial approach. The clinical outcomes were assessed -according to the Rasmussen knee function grading system. The patients were followed-up for an average of 17.5 months (range, 12-32 months). All the fractures attained satisfactory reduction. No major complications were observed. According to the Rasmussen knee function grading system, the results were graded as excellent in 21 cases, good in 13 cases, fair in 2 cases. The rate of excellent and good results was 94.4%. The posteromedial approach in our opinion is the best option to treat the posteromedial tibial plateau fractures because it can provide direct visualization of the fracture site and avoid dissection of neurovascular bundle in the popliteal fossa area with minimal soft tissue injury.

Herein, we constructed a platform of neutral desorption-extractive electrospray ionization mass spectrometry (ND-EESI-MS) for direct and rapid detection of chloramphenicol (CAP) in honey samples diluted with methanol. Under the optimized working conditions, the quantitative information of CAP residues was acquired effectively by EESI-Ion Trap MS (n) . Using heated methanol-N2 as spray reagent, we reduced the limit of determination (LOD) from 73.3 ng/mL to 0.3 ng/mL, and the CAP detection is linear in the range of 1-5000 ng/mL (R = 0.9947). For the honey samples with CAP of 10, 100, and 1000 ng/mL, the recoveries were 133.0, 80.6, and 101.1%, and the relative standard deviations were 5.96, 8.82, and 8.71%, respectively. The reproducibility assays showed the stability of this method. Therefore, this ND-EESI-MS method is powerful for direct, rapid, and quantitative CAP analysis in honey samples with high sensitivity, precision, and specificity.

AIM: To explore the value of 64-section computed tomography (CT) perfusion imaging (CTPI) in the early diagnosis of acute radiation-induced lung injury (ARILI). MATERIALS AND METHODS: Fifty-one patients with oesophageal cancers or malignant thymomas received postoperative radiation therapy with a 60-62 Gy dose and underwent CTPI at pre- and post-radiation therapy time points (week 0, week 4, week 8, and week 12 respectively). The CTPI values were prospectively compared and analysed in order to evaluate the diagnostic utility of CTPI in the early diagnosis of ARILI. RESULTS: Eighteen cases (18/51) of ARILI were diagnosed. The mean values of relative regional blood flow (rrBF), relative regional volume (rrBV), and relative regional permeability surface (rrPS) in the ARILI group were correspondingly higher than those of the non-ARILI group. At week 4, rrBF, rrBV, and rrPS in the ARILI group were significantly higher than those at pre-radiation (each p < 0.05). In the non-ARILI group, rrBF and rrBV were higher than those at pre-radiation (each p < 0.05); however, rrPS was not statistically different from that of pre-irradiation. Applying the diagnostic threshold value of rrPS = 1.22, the sensitivity, specificity, and positive and negative predictive values of CTPI for early diagnosis of ARILI were better than those of CT. CONCLUSION: CTPI metrics may reflect haemodynamic changes in the post-irradiation lung and can detect cases of early ARILI that appear normal at CT. CTPI is a promising technique for early diagnosis of ARILI.

AIM: To evaluate the early success of transarterial embolization (TAE) in patients with traumatic liver haemorrhage and to determine independent factors for its failure. MATERIALS AND METHODS: From January 2009 to December 2012, TAE was performed in 48 patients for traumatic liver haemorrhage. Their medical charts were reviewed for demographic information, pre-TAE vital signs and laboratory data, injury grade, type of contrast medium extravasation (CME) at CT, angiography findings, and early failure. "Early failure" was defined as the need for repeated TAE or a laparotomy for hepatic haemorrhage within 4 days after TAE. Variables were compared between the early success and early failure groups. Variables with univariate significance were also analysed using multivariate logistic regression for predictors of early failure. RESULTS: Among 48 liver TAE cases, nine (18.8%) were early failures due to liver haemorrhage. Early failure was associated with injury grade (p = 0.039), major liver injury (grades 4 and 5; p = 0.007), multiple CMEs at angiography (p = 0.031), incomplete TAE (p = 0.002), and elevated heart rate (p = 0.026). Incomplete embolization (OR = 8; p = 0.042), and heart rate >110 beats/min (bpm; OR = 8; p = 0.05) were independent factors for early failure of TAE in the group with major liver injuries. CONCLUSION: Major hepatic injury is an important factor in early failure. Patients with a heart rate >110 bpm and incomplete embolization in the major injury group have an increased rate of early failure. The success rate of proximal TAE was comparable to that of the more time-consuming, superselective, distal TAE.

OBJECTIVE: To summarise evidence for the diagnostic accuracy of procalcitonin (PCT) tests for identifying systemic bacterial infections in elderly patients. METHODS: Major databases, including MEDLINE, EMBASE and the Cochrane Library, were searched for studies published from 1975 to March 2013 that evaluated PCT as a marker for diagnosing systemic bacterial infections in elderly patients and that provided sufficient data to construct two-by-two tables. RESULTS: Four studies were available for quantitative meta-analysis. The area under a summary receiver operating characteristic curve was 0.89 (95% CI: 0.86-0.92). The overall sensitivity and specificity estimates for PCT tests were 0.83 (95% CI: 0.38-0.98) and 0.83 (95% CI: 0.60-0.94), respectively. These studies reported heterogeneous sensitivity estimates ranging from 0.24 to 0.96. The positive likelihood ratio for PCT (LR+ = 4.77; 95% CI: 2.49-9.13) was not sufficiently high for its use as a rule-in diagnostic tool, while its negative likelihood ratio was acceptably low for its use as a rule-out diagnostic tool (LR- = 0.20; 95% CI: 0.04-0.97). CONCLUSIONS: Existing data suggest that PCT tests may add to the diagnosis of sepsis in elderly patients. We did not observe the performance of the PCT test in elderly patients inferior to adult patients. Given the imperfect accuracy, we do not recommend that the PCT test be used in isolation; instead, we suggest that it be interpreted in the context of clinical findings.

BACKGROUND: There has been a rapid increase in the number of human adenovirus type 7 (HAdV-7) and invasive pulmonary fungal infections (IPFIs) co-infection. METHODS: In this study, we included patients with confirmed HAdV-7 infection during the period from 2018 to 2019 to explore clinical characteristics of severe HAdV-7 pneumonia combined with IPFIs. RESULTS: Among the 143 patients, 35 cases were co-infected with IPFIs. Others were assigned to the control group (n Z 108). Patients wereprone to be complicated with respiratory failure, heart failure and hemophagocytic syndromein IPFIs group. Thirty-one species of fungi were detected in the IPFIs group, among whichAspergillus was the most common species. Compared to control group, patients had lowerlevels of WBC, CD3þ T lymphocyte counts and CD19þ B lymphocyte counts in IPFIs group. CONCLUSION: Aspergillus is the most common species in IPFIs combined with severe HAdV-7 pneumonia. For children with severe HAdV-7 pneumonia who are younger, have a long course of disease, and have been admitted to the ICU, we should predict the occurrence of IPFIs when there is multi-system dysfunction and the reduction of CD3+ T lymphocyte counts and CD19+ B lymphocyte counts in course of their disease.

OBJECTIVES: Hyperuricaemia has been linked to reduced renal function, and evidence indicates that it may be associated with acceleration of the decline in glomerular filtration rate (GFR) and progression of chronic kidney disease (CKD). METHODS: We analysed a population of subjects who had undergone serum uric acid (SUA) and serum creatinine measurements in a hospital-based cohort. Initial and final serum creatinine measurements were used to calculate the estimated glomerular filtration rate (eGFR) and the annual decline in eGFR. Cox regression was used to investigate the relationship between SUA and CKD progression. RESULTS: A total of 63,785 subjects were enrolled in the study during a 12-year follow-up period. The mean age at the time of initial serum creatinine measurement was 50.0 ± 14.9 years. Hyperuricaemic subjects had a significantly larger annual eGFR decline, both in absolute terms (2.5 ± 9.5 mL/min/1.73 m(2) per year) and as a percentage (2.8 ± 11.6% per year), as compared to the normouricaemia group (1.3 ± 9.6 mL/min/1.73 m(2) per year, 1.1 ± 11.1% per year, p < 0.001). After adjustment for age, sex, status of diabetes mellitus (DM) and hypertension, baseline eGFR, azotaemia, hypercholesterolaemia, and hyperglycaemia, hyperuricaemia was associated with a hazard ratio (HR) of 1.28 [95% confidence interval (CI) 1.23-1.33, p < 0.001] for an accelerated eGFR decline ≥ 3 mL/min/1.73 m(2) per year and an HR of 1.52 (95% CI 1.46-1.59) for CKD progression at the end of follow-up. CONCLUSION: Hyperuricaemia was associated with an accelerated decline in eGFR and higher risk of CKD progression. Therefore, renal function should be monitored closely in patients with hyperuricaemia.

The purpose of this study was to develop a Physician's Spiritual Well-Being Scale (PSpWBS). The significance of a physician's spiritual well-being was explored through in-depth interviews with and qualitative data collection from focus groups. Based on the results of qualitative analysis and related literature, the PSpWBS consisting of 25 questions was established. Reliability and validity tests were performed on 177 subjects. Four domains of the PSpWBS were devised: physician's characteristics; medical practice challenges; response to changes; and overall well-being. The explainable total variance was 65.65%. Cronbach α was 0.864 when the internal consistency of the whole scale was calculated. Factor analysis showed that the internal consistency Cronbach α value for each factor was between 0.625 and 0.794 and the split-half reliability was 0.865. The scale has satisfactory reliability and validity and could serve as the basis for assessment of the spiritual well-being of a physician.

OBJECTIVES: To investigate the association between gout and non-alcoholic fatty liver disease (NAFLD). METHODS: The study subjects were participants in a health-screening programme at Chang Gung Memorial Hospital from 2000 to 2006. Subjects were classified into eight groups based on serum urate (SU) level and gout status (≤ 4.9, 5.0-6.9, 7.0-8.9, and ≥ 9.0 mg/dL, without and with gout). The association between gout and NAFLD was assessed by multiple logistic regression. RESULTS: Among a total of 54 325 subjects, 1930 (3.6%) had gout and 6169 (11.3%) had NAFLD. The prevalence of NAFLD was significantly higher in subjects with gout (23.1%, n = 445) than in those without gout (10.9%, n = 5724, p < 0.001). Among subjects with NAFLD, the severity of NAFLD was higher in gout patients. Gout was associated with an increased risk for NAFLD [odds ratio (OR) 1.42, 95% confidence interval (CI) 1.25-1.60, p < 0.001], after adjustment for age, sex, presence of metabolic syndrome, and low estimated glomerular filtration rate (eGFR). With SU ≤ 4.9 mg/dL in the absence of gout as reference, the ORs (95% CI) for NAFLD, after adjustment for age, sex, presence of metabolic syndrome, and low eGFR, were, respectively, 2.16 (1.94-2.41), 3.98 (3.55-4.46), and 5.99 (5.19-6.90) for SU levels 2-4 in those without gout and 2.61 (1.39-4.91), 2.87 (2.04-4.04), 4.53 (3.70-5.56), and 6.31 (5.12-7.77) for SU levels 1-4 in those with gout. CONCLUSIONS: There was an independent association between gout and the risk for NAFLD. In addition, there was a dose-response relationship between SU and NAFLD in subjects with and without gout.

The aim of this study was to evaluate the support to tuberculosis diagnosis of a new immunological tool, an enzyme-linked immunospot (ELISPOT) assay for interferon-γ, in diabetic patients. From March 2007 to January 2008, diabetic patients with suspected pulmonary tuberculosis were enrolled in a tertiary care hospital. Data on clinical characteristics of the patients and conventional laboratory results were collected and blood samples were obtained for ELISPOT assay (T SPOT-TB; Oxford Immunotec Ltd, Oxford, UK). A total of 84 patients with suspected pulmonary tuberculosis were recruited. Fifty-one (60.7%) of these patients were considered to have pulmonary tuberculosis, including 42 (50%) with confirmed tuberculosis and 9 (10.7%) with probable tuberculosis. The overall (confirmed and probable tuberculosis) sensitivity, specificity, positive predictive value and negative predictive value of the ELISPOT assay were 84.3%, 66.7%, 79.6%, and 73.3%, respectively. The negative predictive value of the ELISPOT assay was significantly higher in patients with adequate glycaemic control (90% vs 56.3%). In conclusion, the ELISPOT assay can provide useful support in diagnosing pulmonary tuberculosis in diabetic patients, especially those with adequate glycaemic control.
