RESUMO
BACKGROUND: In conventional practice, the left double lumen tube (DLT) is rotated 90° counterclockwise when the endobronchial cuff passes glottis. Success rate upon the first attempt is < 80%, likely owing to varying morphology of the bronchial bifurcation. METHODS: We conducted a randomized controlled trial to compare 90° counterclockwise rotation versus individualized degree of rotation in adult patients undergoing elective thoracic surgery using left DLT. The degree of rotation in the individualized group was based on the angle of the left main bronchi as measured on computed tomography (CT). The primary outcome was the first attempt left DLT placement success rate. RESULTS: A total of 556 patients were enrolled: 276 in the control group and 280 in the individualized group. The average angle of the left main bronchi was 100.6±9.5° (range 72° to 119°). The first attempt left DLT placement success rate was 82.6% (228/276) in the control group versus 91.4% (256/280) in the individualized group (P=0.02, χ2 test). The rate of carina mucosal injury, as measured at 30 min after the start of surgery under fibreoptic bronchoscopy, was significantly lower in individualized group than control group (14.0% versus 19.6%, P=0.041). The individualized group also had lower rate of postoperative sore throat (29.4% versus 44.0%, P<0.001) and hoarseness (16.8% versus 24.7%, Pï¼0.05). CONCLUSIONS: Individualized rotation of left DLT based on the angle of the left main bronchi on preoperative CT increased first attempt success rate in adult patients undergoing elective thoracic surgery. TRIAL REGISTRATION: The trial is registered at Chinese Clinical Trial Registry (ChiCTR2100053349; principal investigator Xiang Quan, date of registration November 19, 2021).

PURPOSE: To explore if COVID-19 infection and its subsequent immunosuppressant adjustment as well as previous vaccination status are associated with higher risks of uveitis flare in patients with Behcet's disease. METHODS: This retrospective multicenter cohort study was conducted in January 2023 among patients with Behcet's uveitis, during the second wave of the COVID-19 pandemic in China, with an anticipated sample size of 250. The primary objective was to examine the association between COVID-19 infection and the occurrence of uveitis flare. The potential impact of other exposures, including the patient's vaccination status and treatment adjustments to the risk of uveitis flare and the course of COVID-19 infection were also analyzed. RESULTS: 207 patients with COVID-19 infection and 47 patients without COVID-19 infection were included. A total of 127 uveitis flares occurred in the observational period (14.29 events per 100 person-month). COVID-19 infection was found to be significantly associated with a higher rate of uveitis flare (adjusted rate ratio = 4.8, 95% CI 3.7 to 6.3, P < 0.001). However, neither systemic immunosuppressive adjustment nor COVID-19 vaccination status showed a significant association with uveitis flare or the course of COVID-19 infection. CONCLUSIONS: This study provides evidence of an association between COVID-19 infection and an increased risk of uveitis flare in patients with Behcet's disease. However, there was no significant evidence to support that baseline immunosuppressive therapy regimens, treatment adjustment after COVID-19 infection, or vaccination status were associated with higher risks of uveitis flare or prolonged COVID-19 course.
RESUMO
BACKGROUND: Endotracheal intubation is challenging during cardiopulmonary resuscitation, and video laryngoscopy has showed benefits for this procedure. The aim of this study was to compare the effectiveness of various intubation approaches, including the bougie first, preloaded bougie, endotracheal tube (ETT) with stylet, and ETT without stylet, on first-attempt success using video laryngoscopy during chest compression. METHODS: This was a randomized crossover trial conducted in a general tertiary teaching hospital. We included anesthesia residents in postgraduate year one to three who passed the screening test. Each resident performed intubation with video laryngoscopy using the four approaches in a randomized sequence on an adult manikin during continuous chest compression. The primary outcome was the first-attempt success defined as starting ventilation within a one minute. RESULTS: A total of 260 endotracheal intubations conducted by 65 residents were randomized and analyzed with 65 procedures in each group. First-attempt success occurred in 64 (98.5%), 57 (87.7%), 56 (86.2%), and 46 (70.8%) intubations in the bougie-first, preloaded bougie, ETT with stylet, and ETT without stylet approaches, respectively. The bougie-first approach had a significantly higher possibility of first-attempt success than the preloaded bougie approach [risk ratio (RR) 8.00, 95% confidence interval (CI) 1.03 to 62.16, P = 0.047], the ETT with stylet approach (RR 9.00, 95% CI 1.17 to 69.02, P = 0.035), and the ETT without stylet approach (RR 19.00, 95% CI 2.62 to 137.79, P = 0.004) in the generalized estimating equation logistic model accounting for clustering of intubations operated by the same resident. In addition, the bougie first approach did not result in prolonged intubation or increased self-reported difficulty among the study participants. CONCLUSIONS: The bougie first approach with video laryngoscopy had the highest possibility of first-attempt success during chest compression. These results helped inform the intubation approach during CPR. However, further studies in an actual clinical environment are warranted to validate these findings.

BACKGROUND: Accurate self-assessment is crucial for the professional development of physicians. There has been sparse data on the accuracy of self-assessments on Anesthesiology Milestones. The aim of this study was to investigate the differences between resident self-assessments and faculty-assessments on Anesthesiology Milestones and the associated factors. METHODS: This was a cross-sectional study conducted in a general tertiary university-affiliated hospital. We included anesthesia residents who were enrolled in the standardized residency training program in postgraduate year two and three at the time of the Milestone evaluation. We requested evaluations of competencies from both the Clinical Competency Committee faculty and the anesthesia residents themselves, utilizing the Chinese version of Anesthesiology Milestones in January 2023 and January 2024. The primary outcome was the differences between self- and faculty-assessments, calculated by subtracting the faculty-rated score from the self-rated score on each subcompetency. RESULTS: A total of 46 and 42 residents were evaluated in year 2023 and 2024, respectively. The self-rated sum score was significantly higher than that rated by faculty [mean (standardized deviation): 120.39 (32.41) vs. 114.44 (23.71), P = 0.008 in paired t test] with an intraclass correlation coefficient of 0.55 [95% confidence interval (CI): 0.31 to 0.70]. The Bland-Altman plots revealed significant overestimation in patient care (bias 0.32, 95% CI: 0.05 to 0.60), practice-based learning and improvement (bias 0.45, 95% CI: 0.07 to 0.84), and professionalism (bias 0.37, 95% CI: 0.02 to 0.72). Ratings from residents with master's degrees (mean difference: -1.06, 95% CI: -1.80 to -0.32, P = 0.005) and doctorate degrees (mean difference: -1.14, 95% CI: -1.91 to -0.38, P = 0.003) were closer to the faculty-assessments than residents with bachelor's degrees. Compared with patient care, the differences between self- and faculty- rated scores were smaller in medical knowledge (mean difference: -0.18, 95% CI: -0.35 to -0.02, P = 0.031) and interpersonal and communication skills (mean difference: -0.41, 95% CI: -0.64 to -0.19, P < 0.001) in the generalized estimating equation logistic regression model. CONCLUSIONS: This study revealed that residents tended to overestimate themselves, emphasizing the need to improve the accuracy of Milestones self-assessment. The differences between self- and faculty-assessments were associated with residents' degrees and domains of competency.

Objective To assess the diagnostic accuracy of bowel sound analysis for irritable bowel syndrome (IBS) with a systematic review and meta-analysis. Methods We searched MEDLINE, Embase, the Cochrane Library, Web of Science, and IEEE Xplore databases until September 2023. Cross-sectional and case-control studies on diagnostic accuracy of bowel sound analysis for IBS were identified. We estimated the pooled sensitivity, specificity, positive likelihood ratio, negative likelihood ratio, and diagnostic odds ratio with a 95% confidence interval (CI), and plotted a summary receiver operating characteristic curve and evaluated the area under the curve. Results Four studies were included. The pooled diagnostic sensitivity, specificity, positive likelihood ratio, negative likelihood ratio, and diagnostic odds ratio were 0.94 (95% CI, 0.87-0.97), 0.89 (95% CI, 0.81-0.94), 8.43 (95% CI, 4.81-14.78), 0.07 (95% CI, 0.03-0.15), and 118.86 (95% CI, 44.18-319.75), respectively, with an area under the curve of 0.97 (95% CI, 0.95-0.98). Conclusions Computerized bowel sound analysis is a promising tool for IBS. However, limited high-quality data make the results' validity and applicability questionable. There is a need for more diagnostic test accuracy studies and better wearable devices for monitoring and analysis of IBS.

PURPOSE: To compare patient-controlled epidural analgesia (PCEA) and epidural morphine (EM) for post-cesarean section analgesia in real-world experience from China. METHODS: Parturients receiving one dose of EM (1-2 mg), PCEA, or both EM and PCEA from Peking Union Medical College Hospital were retrospectively recruited. Logistic models were used to identify risk factors. RESULTS: Of 1079 parturients enrolled, 919 (85.2%) parturients received only EM, 105 (9.7%) parturients received PCEA, and 55 (5.1%) parturients received both EM and PCEA. Significantly more parturients from EM group requested supplementary analgesia than those from PCEA and PCEA + EM group (583, 63.4% vs 52, 49.5% vs 25, 45.5%, P = 0.001) with more times of supplementary analgesia (1, IQR: 0-2 vs 0, IQR: 0-1 vs 0, IQR: 0-1 times, P < 0.001) and larger amounts of nonsteroidal anti-inflammatory drugs (NSAIDs) (50, IQR: 0-100 mg vs 0, IQR: 0-50 mg vs 0, IQR: 0-50 mg, P < 0.001). In multivariable Logistic regression for the supplementary analgesia risk, the application of PCEA (OR: 0.557, 95%CI 0.396-0.783, P = 0.001) and the use of NSAIDs intraoperatively (OR: 2.996, 95%CI 1.811-4.957, P < 0.001) were identified as independent predictors. A total of 1040 (96.4%) patients received prophylactic antiemetic therapy during surgery. Only 13 (1.2%) and 7 (0.6%) patients in our cohort requested antiemetic and antipruritic drugs, respectively. CONCLUSION: The use of PCEA was an independent protective factor for supplementary analgesia during the post-cesarean section. Prophylactic antiemetic therapy may reduce the side effects of post-cesarean analgesia.
RESUMO
BACKGROUND: Doxycycline was demonstrated in a retrospective study to be associated with greater survival in patients with light chain amyloidosis. Therefore, we prospectively compared the efficacy of bortezomib-cyclophosphamide-dexamethasone (CyBorD) and CyBorD combined with doxycycline for cardiac light chain amyloidosis. METHODS: This was a multicenter, open-label, randomized controlled trial. Patients with Mayo 2004 stage II to III light chain amyloidosis were included. Patients were randomized to doxycycline 100 mg twice daily along with 9 cycles of CyBorD (doxycycline group) or to 9 cycles of CyBorD alone (control group). The primary outcome was 2-year progression-free survival (PFS). PFS was defined as the time from randomization to death, hematologic progression, or organ progression (heart, kidney or liver). Hematologic progression was defined on the basis of a substantial increase in free light chain. An increase in either NT-proBNP (N-terminal pro B-type natriuretic peptide) or cardiac troponin was the main criterion for defining cardiac progression. Cardiac PFS, defined as the time from randomization to cardiac progression or death, was compared between groups in an exploratory analysis. The corresponding treatment hazard ratio was estimated with a Cox regression model. RESULTS: One hundred forty patients underwent randomization, with 70 in each group. The median age was 61 years (range, 33-78 years) with a male:female ratio of 1.75:1. Stage II disease was present in 34 (48.6%) and 33 (47.1%) patients in the doxycycline and control groups, respectively. After a median follow-up duration of 24.4 months, 32 of 70 (45.7%) patients in the doxycycline group and 30 of 70 (42.9%) patients in the control group experienced progression. PFS was not significantly different between groups (hazard ratio, 0.97 [95% CI, 0.59-1.60]; P=0.91). Cardiac progression occurred in 29 of 70 (41.4%) patients in the doxycycline group and 26 of 70 (37.1%) patients in the control group. The death rates for both groups by the end of follow-up was the same, 25 of 70 (35.7%). No significant differences were observed for either cardiac PFS (hazard ratio, 0.91 [95% CI, 0.54-1.55]; P=0.74) or overall survival (hazard ratio, 1.04 [95% CI, 0.60-1.81]; P=0.89). CONCLUSIONS: Our trial demonstrated that doxycycline combined with CyBorD failed to prolong PFS or cardiac PFS compared with CyBorD alone in cardiac light chain amyloidosis.

Antinuclear antibody (ANA) can be positive in children with primary immune thrombocytopenia (ITP), but the effect of ANA titre and its variation on outcomes of children with primary ITP remains unclear. Here, we conducted a single-centre retrospective cohort study of children with primary ITP at the Peking Union Medical College Hospital in China. A total of 324 children with primary ITP included in this study were followed for a median time of 25 months. In this cohort, 39.2% had an ANA titre of 1:160 or higher. Results from a generalized estimating equation model revealed that patients with higher ANA titres had lower platelet counts at onset but a higher recovery rate of subsequent platelet counts. Results from Cox regression models adjusted for potential confounders revealed that patients with ANA titres of 1:160 or more were more likely to develop to autoimmune disease (AID) than those without, and the risk of AID development increased with the rise of ANA titres (p value for trend less than 0.001). These data highlight the predictive value of ANA titre for platelet counts and the risk of AID development in children with primary ITP.

OBJECTIVE: The aim of this study was to investigate the association between storage time of transfused red blood cells and risks of infections after clean-contaminated surgery. SUMMARY BACKGROUND DATA: Storage lesions of red blood cells can aggravate transfusion-related immunomodulation. Very few randomized controlled trials have investigated the impacts of storage time on postoperative outcomes in non-cardiac patients. METHODS: We included adult patients who had undergone clean-contaminated surgery from 2014 to 2018 and received allogeneic red blood cell transfusion. In transfusion episode-level analysis, the exposure was the storage time of each transfusion episode. In patient-level analysis, the exposures were the mean, weighted mean, maximum storage time, and Scalar Age of Blood Index of red blood cells transfused into each patient. The primary outcome was infections that developed after transfusions within postoperative Day 30. RESULTS: The 4046 included patients received 11604 transfusion episodes. Of these, 1025 (25.3%) patients developed postoperative infections. An increased storage time of transfused red blood cells was not associated with increased odds of postoperative infections in either transfusion episode-level analysis [odds ratio (OR) 1.03 per five days, 95% confidence interval (CI) 0.95 to 1.11] or patient-level analysis (mean: OR 1.02, 95% CI 0.95 to 1.10; weighted mean: OR 1.02, 95% CI 0.95 to 1.10; maximum: OR 1.06, 95% CI 0.98 to 1.14; Scalar Age of Blood Index: OR 0.99, 95% CI 0.96 to 1.03), after adjusting 17 confounders. CONCLUSIONS: Prolonged storage time of transfused red blood cells was not associated with increased risks of infections after clean-contaminated surgery.
RESUMO
OBJECTIVE: Hypothalamic dysfunction is characterized by complex aetiologies, multiple forms of onset and various clinical symptoms. This study aims to explore the clinical and metabolic characteristics of hypothalamic dysfunction in Chinese children and adolescents. DESIGN: This study is a single-centre, retrospective study that covers patients from 1989 to 2019. PATIENTS: We included 40 children and adolescents with hypothalamic dysfunction from our medical centre in Beijing, China. RESULTS: Intracranial tumour (37.5%) was the most common aetiology of children and adolescents with hypothalamic dysfunction, especially germ cell tumours, hypopituitarism (82.5%), weight gain (72.5%) and central diabetes insipidus (70.0%) were the most common symptoms in these patients. Furthermore, serum alanine aminotransferase, aspartate aminotransferase, γ-glutamyl transpeptidase, uric acid, total cholesterol, triglycerides and low-density lipoprotein cholesterol was significantly higher in hypothalamic dysfunction patients than sex- and age-matched controls and sex, age and body mass index (BMI)-matched controls (all p < 0.05). However, albumin and high-density lipoprotein cholesterol were lower (p< 0.05). Moreover, 95% (38/40) of the patients had metabolic diseases. In addition, the incidence of dyslipidaemia and hyperuricemia in children and adolescents with hypothalamic dysfunction was significantly higher than both sex- and age-matched controls and sex-, age- and BMI-matched controls (both p < 0.05) as well. CONCLUSIONS: Intracranial tumour was the most common aetiology in children and adolescents with hypothalamic dysfunction. In addition, these patients presented a worse metabolic profile on average than healthy patients.

BACKGROUND AND OBJECTIVES: Transfusion-related guidelines promote restrictive blood transfusion. However, whether these guidelines have been successfully translated into clinical practice in China is unknown. This study aimed to provide updated information about the temporal trends in the prevalence of perioperative red blood cell (RBC) transfusion in China. MATERIALS AND METHODS: We analysed data from the Hospital Quality Monitoring System database (2013-2018) to investigate the prevalence of perioperative RBC transfusion in patients undergoing craniotomy for cerebral aneurysms or arteriovenous malformations, sternotomy for mitral valve replacement, open thoracotomy lobectomy, open gastrectomy and hip arthroplasty. Mixed-effects logistic regression models quantified the likelihood of RBC transfusions. RESULTS: The study included 438,183 patients, with 44,697 (10.20%) receiving perioperative RBC transfusions. Introducing transfusion-related guidelines in China markedly decreased the prevalence of RBC transfusion among patients who underwent major surgical procedures in the following years. The prevalence of RBC transfusion for hip arthroplasty was 17.34% in 2013 and 7.03% in 2018. After adjusting for patient risk factors, the odds ratio of RBC transfusion for hip arthroplasty was significantly lower in 2018 (0.74, 95% confidence intervals [CI] 0.53-1.02) than in 2013 (1.84, 95% CI 1.37-2.48). CONCLUSION: The prevalence of perioperative RBC transfusion decreased from 2013 to 2018 in China, supporting the potential beneficial effects of transfusion-related guidelines. Considering the geographic variations in RBC transfusion, reducing heterogeneity may impact public health by improving surgical outcomes.

OBJECTIVES: Systemic sclerosis (SSc) is characterised by vasculopathy and progressive fibrosis of the skin. The aim of this article is to analyse and summarise the efficacy and safety of autologous fat (AF), stromal vascular fraction (SVF) and adipose-derived stem cell (ADSC) grafting in the treatment of SSc, providing evidence for clinical application. METHODS: The research involves the efficacy and safety of AF, SVF and ADSC grafting in the treatment of patients with SSc. The studies were screened and selected independently by two authors based on pre-specified criteria. The data extraction and quality assessment were also performed independently by two authors. RESULTS: Fifteen studies were eligible for inclusion. Skin thickness reduced following SVF or AF therapy, but there was no significant difference. All measures used to assess fingertip symptoms revealed a significant improvement. Notably, SVF and AF were found to have the most impact on Raynaud's phenomenon improvement. The ADSC group improved the most in terms of finger pain alleviation. SVF reported the highest proportion of adverse events, accounting for approximately half of the cases. CONCLUSIONS: AF, SVF, and ADSC all displayed therapeutic effects of improving SSc, but differences existed in the effects on different symptoms. Plastic surgeons should choose the most suitable treatment strategy after comprehensively evaluating the patient's clinical manifestations.

BACKGROUND: Current studies did not draw definitive conclusions on comparison of intracorporeal anastomosis (ICA) with extracorporeal anastomosis (ECA) in laparoscopic right colectomy. Whether the intraperitoneal contamination induced by ICA can result in higher risk of postoperative abdominal infection remains unclear. This study was aimed to compare the short-term outcomes, especially the risk of abdominal infection after ICA versus ECA. METHODS: This was an observational cohort study as a secondary analysis of a randomized controlled trial (RCT)-RELARC trial (NCT02619942). The patients enrolled in the RELARC trial were diagnosed with primary colon adenocarcinoma without distant metastasis and underwent radical laparoscopic right colectomy between Jan 2016 and Dec 2019. In our study the patients who converted to open surgery in RELARC trial were excluded. The short-term outcomes were compared between ICA and ECA. The primary endpoint was abdominal infection. The inverse probability of treatment weighting (IPTW) and propensity score matching (PSM) was used for adjusting the potential confounders. RESULTS: This study enrolled 975 patients with 119 patients undergoing ICA and 856 patients undergoing ECA. The incidence of abdominal infection was higher in ICA group (9.2% versus 1.5%, RR from IPTW = 5.7 (95%CI: 2.6-12.6), P < 0.001) as well as the incidence of wound infection (14.3% vs 3.3%, RR from IPTW = 5.0 (95%CI: 2.9-8.6), P < 0.001). ICA was associated with higher incidence of Clavien-Dindo (CD) grade I and II complications (CD-I: 15.1% versus 6.8%, RR from IPTW = 2.4 (95%CI: 1.5-3.9), P < 0.001; CD-II: 26.9% versus 8.2%, RR from IPTW = 3.6 (95%CI: 2.5-5.1), P < 0.001) but similar incidence of CD-III ~ IV complications compared to ECA (3.4% vs 2.1%, RR from IPTW = 1.2 (95%CI: 0.4-4.0), P = 0.73). In ICA group, choosing another incision rather than lengthening main port site decreased the incidence of wound infection although without statistical significance (17.3% (14/81) versus 7.9% (3/38), crude RR = 2.2 (95%CI: 0.7-7.2), P = 0.17). CONCLUSION: ICA is likely to be associated with higher risk of abdominal infection and CD-I ~ II complications.

BACKGROUND: Breast milk is of great benefit to both infants and mothers. Due to occupational barriers, female physicians are at high risk of unintentionally discontinuing breastfeeding. However, evidence among anesthesiologists was limited. The purpose of this study was to investigate occupational factors associated with time to breastfeeding discontinuation among female anesthesiologists following maternity leave in China. METHODS: We conducted a nationwide survey of female anesthesiologists who had given birth since January 1, 2015. A 60-item anonymous questionnaire was developed to collect information regarding breastfeeding practices and related factors. The questionnaire was revised based on the recommendations of 15 experts and feedback from the pilot survey. The survey was distributed by the Chinese Society of Anesthesiology. RESULTS: The completion rate was 57.9%. In total, 1364 responders were analyzed from all 31 provinces of Mainland China. In total, 1311 (96.1%) responders reported a reduction in breast milk supply on returning to work. Among the 1161 responders who discontinued breastfeeding, 836 (72.0%) did not achieve desired goals due to occupational factors. The median [interquartile range] of maternity leave length and breastfeeding duration were 5 [4-6] months and 10 [7-12] months, respectively. The following occupational factors were associated with longer time to breastfeeding discontinuation after adjusting for confounding effects of personal factors: length of maternity leave (hazard ratio [HR] per month 0.44; 95% confidence interval [CI], 0.36-0.54; P < .001), pumping breast milk during work time (HR, 0.04; 95% CI, 0.02-0.08; P < .001), support from colleagues (HR, 0.92; 95% CI, 0.86-0.99; P = .032), and additional nonclinical activities (HR, 0.87; 95% CI, 0.77-0.98; P = .022). Trainees under supervision (HR, 1.20; 95% CI, 1.06-1.43; P = .005) and the need to remain in the operating room during cases (HR, 2.59; 95% CI, 1.09-6.12; P = .031) were associated with shorter time to breastfeeding discontinuation. Approximately 899 (65.9%) responders pumped breast milk during work time. Among them, reduction in pumping frequency (HR, 1.17; 95% CI, 1.00-1.36; P = .049) and difficulty in finding opportunities for pumping (HR, 2.34; 95% CI, 1.36-4.03; P = .002) were associated with shorter time to breastfeeding discontinuation. CONCLUSIONS: We identified modifiable occupational factors associated with time to breastfeeding discontinuation. These findings underscored the necessity of facilitating breastfeeding in the workplace, including encouraging longer maternity leave and breastfeeding breaks, considering the feasibility of pumping in daily case assignments, establishing supportive culture, providing lactation rooms, and offering nonclinical activities.
RESUMO
OBJECTIVE: Previous studies have shown inconsistent results regarding the usefulness of prolactin adjustment in bilateral inferior petrosal sinus sampling (BIPSS) in the differential diagnosis of adrenocorticotropic hormone (ACTH)-dependent Cushing syndrome (CS). This meta-analysis compared the diagnostic accuracy of prolactin adjustment versus no adjustment in BIPSS. METHODS: This study searched the PubMed, Embase, Web of Science, Cochrane library, and WanFang databases for published data as of March 2022 on the use of prolactin adjustment in BIPSS to differentially diagnose ACTH-dependent CS. A Bayesian joint bivariate model was used in the head-to-head comparison of the diagnostic accuracy. RESULTS: This meta-analysis included a total of 10 studies with 300 patients. The combined sensitivity and specificity for BIPSS without prolactin adjustment were 94.47% (95% CI, 88.67%-98.44%) and 91.14% (95% CI, 57.17%-99.80%), respectively. The combined sensitivity and specificity after prolactin adjustment were 99.97% (95% CI, 99.03%-100.00%) and 80.69% (95% CI, 50.27%-97.82%), respectively. After the prolactin adjustment, the sensitivity of BIPSS to diagnose Cushing disease was improved with a statistically significant difference (difference in sensitivity, 5.39%; 95% CI, 1.37%-11.26%), whereas the decrease in specificity was without a statistically significant difference (difference in specificity, -9.20%; 95% CI, -42.02% to 26.61%). CONCLUSION: This meta-analysis indicated that prolactin adjustment in BIPSS might help to recognize Cushing disease among patient with ACTH-dependent CS. However, prolactin adjustment may not help identify ectopic ACTH syndrome in BIPSS.

BACKGROUND: Perioperative fluid management during major abdominal surgery has been controversial. Postoperative pancreatic fistula (POPF) is a critical complication of pancreaticoduodenectomy (PD). We conducted a retrospective cohort study to analyze the impact of intraoperative fluid balance on the development of POPF. METHODS: This retrospective cohort study enrolled 567 patients who underwent open pancreaticoduodenectomy, and the demographic, laboratory, and medical data were recorded. All patients were categorized into four groups according to quartiles of intraoperative fluid balance. Multivariate logistic regression and restricted cubic splines (RCSs) were used to analyze the relationship between intraoperative fluid balance and POPF. RESULTS: The intraoperative fluid balance of all patients ranged from -8.47 to 13.56 mL/kg/h. A total of 108 patients reported POPF, and the incidence was 19.0%. After adjusting for potential confounders and using restricted cubic splines, the doseâresponse relationship between intraoperative fluid balance and POPF was found to be statistically insignificant. The incidences of bile leakage, postpancreatectomy hemorrhage, and delayed gastric emptying were 4.4%, 20.8%, and 14.8%, respectively. Intraoperative fluid balance was not associated with these abdominal complications. BMI ≥ 25 kg/m2, preoperative blood glucose < 6 mmol/L, long surgery time, and lesions not located in the pancreas were independent risk factors for POPF. CONCLUSION: The study did not find a significant association between intraoperative fluid balance and POPF. Well-designed multicenter studies are necessary to explore the association between intraoperative fluid balance and POPF.

BACKGROUND: We aimed to investigate the effects of intermittent bolus paravertebral block on analgesia and recovery in open hepatectomy. METHODS: Eighty 18-70 years old, American Society of Anesthesiologists level I-III patients scheduled for hepatectomy with a J-shaped subcostal incision were enrolled and randomized to receive either intermittent bolus paravertebral ropivacaine (0.5% loading, 0.2% infusion) or 0.9% saline infusion at 1:1 ratio (25 ml loading before surgery, 0.125 ml/kg/h bolus for postoperative 48 h). The primary outcome was set as postoperative 48 h cumulative intravenous morphine consumption recorded by a patient-controlled analgesic pump. RESULTS: Thirty-eight patients in each group completed the study. The cumulative morphine consumptions were lower in the paravertebral block than control group at postoperative 24 (difference -10.5 mg, 95%CI -16 mg to -6 mg, P < 0.001) and 48 (difference -12 mg, 95%CI -19.5 mg to -5 mg, P = 0.001) hours. The pain numerical rating scales at rest were lower in the paravertebral block than control group at postoperative 4 h (difference -2, 95%CI -3 to -1, P < 0.001). The active pain numerical rating scales were lower in the paravertebral block than control group at postoperative 12 h (difference -1, 95%CI -2 to 0, P = 0.005). Three months postoperatively, the paravertebral block group had lower rates of hypoesthesia (OR 0.28, 95%CI 0.11 to 0.75, P = 0.009) and numbness (OR 0.26, 95%CI 0.07 to 0.88, P = 0.024) than the control group. CONCLUSIONS: Intermittent bolus paravertebral block provided an opioid-sparing effect and enhanced recovery both in hospital and after discharge in patients undergoing hepatectomy.

Objective Although goal-directed fluid therapy (GDFT) has been proven to be effective in reducing the incidence of postoperative complications, the underlying mechanisms remain unknown. The aim of this study was to examine the mediating role of intraoperative hemodynamic lability in the association between GDFT and the incidence of postoperative complications. We further tested the role of this mediation effect using mean arterial pressure, a hemodynamic indicator. Methods This secondary analysis used the dataset of a completed nonrandomized controlled study to investigate the effect of GDFT on the incidence of postoperative complications in patients undergoing posterior spine arthrodesis. We used a simple mediation model to test whether there was a mediation effect of average real variability between the association of GDFT and postoperative complications. We conducted mediation analysis using the mediation package in R (version 3.1.2), based on 5,000 bootstrapped samples, adjusting for covariates. Results Among the 300 patients in the study, 40% (120/300) developed postoperative complications within 30 days. GDFT was associated with fewer 30-day postoperative complications after adjustment for confounders (odds ratio: 0.460, 95% CI: 0.278, 0.761; P = 0.003). The total effect of GDFT on postoperative complications was -0.18 (95% CI: -0.28, -0.07; P < 0.01). The average causal mediation effect was -0.08 (95% CI: -0.15, -0.04; P < 0.01). The average direct effect was -0.09 (95% CI: -0.20, 0.03; P = 0.17). The proportion mediated was 49.9% (95% CI: 18.3%, 140.0%). Conclusions The intraoperative blood pressure lability mediates the relationship between GDFT and the incidence of postoperative complications. Future research is needed to clarify whether actively reducing intraoperative blood pressure lability can prevent postoperative complications.

PURPOSE: The objective of this study was to provide an updated review on the active warming effects on major adverse cardiac events, 30-day all-cause mortality, and myocardial injury after noncardiac surgery. METHOD: We systematically searched MEDLINE, EMBASE, CINAHL, Cochrane CENTRAL, Web of Science, and Chinese BioMedical Literature Database. We included randomized controlled trials of adult population undergoing noncardiac surgeries that concentrate on the comparison of active warming methods and passive thermal management. Cochrane Collaboration's tool was applied for risk-of-bias assessment. We used trial sequential analysis to evaluate the possibility of false positive or negative results. RESULTS: A total of 13,316 unique records were identified, of which only 19 with reported perioperative cardiovascular outcomes were included in the systematic review and nine of them were included in final meta-analysis. No statistically significant difference between active warming methods and routine care was found in major adverse cardiac events (RR 0.56, 95% confidence interval (CI) 0.14-2.21, I2 = 71%, number of events 59 vs. 70), 30-day all-cause mortality (RR 0.81, 95% CI 0.43-1.54, I2 = 0%, number of events 17 vs. 21), and myocardial injury after noncardiac surgery (RR 0.61, 95% CI 0.17-2.22, I2 = 79%, number of events 236 vs. 234). Trial sequential analysis suggests that current trials did not reach the minimum information size regarding the major cardiovascular events. CONCLUSIONS: Compared to routine perioperative care, we found that active warming methods are not necessary for cardiovascular prevention in patients undergoing noncardiac surgery.

Immune thrombocytopenia (ITP) patients are at risk developing to systemic lupus erythematosus (SLE) in the future. Our study attempted to explore the potential risk factors for the development from ITP to SLE in Chinese children by statistical analysis. This study was a retrospective case-control study. Patients diagnosed with ITP and developed to SLE after the diagnosis of ITP were defined as the case group. The control group consisted of children with ITP but without developing to SLE was recruited with a ratio of 1:2. Besides univariable analysis, multivariable logistic regression was built to evaluate the potential risk factors. A total of 150 children was included with 50 in the case group and 100 in the control group. Median developing time from ITP to SLE was 34.5 [IQR 12.5, 58.75] months. ANA was found significantly different between the two groups in our study in the univariable analysis but not in the multivariable analysis (OR = 4.50, 95% CI 0.97 to 21.01). Age diagnosed ITP was positively associated with SLE (OR = 1.07 every 5 years, 95% CI 1.01 to 1.15) with alert point at 8 years old (sensitivity 0.82, specificity 0.60). A lower level of complement was also positively associated with SLE (OR = 8.33, 95% CI 1.62 to 42.91). A minimum 3-year of close follow-up for pediatric ITP patients was recommended to monitor the risk for developing SLE. Older age and hypocomplementemia were potential risk factors for the development from ITP to SLE.
