RESUMEN

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.

RESUMEN

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.

RESUMEN

BACKGROUND: Evidence has shown that large-scale pandemics can have prolonged psychological impacts on health care professionals. The current study aimed to evaluate the prevalence of burnout after the coronavirus disease 2019 (COVID-19) epidemic peak and to explore the prolonged impact of COVID-19 on burnout among Chinese anesthesiologists. METHODS: From August 2021 to October 2021, a nationwide cross-sectional survey was conducted. Burnout was measured using the Maslach Burnout Inventory-Human Service Survey. Basic demographic information, exposure to COVID-19, and perceived institutional support were documented. Validated tools measuring mental health status, including anxiety, depression, post-traumatic stress disorder (PTSD) and resilience, were also used to provide additional information on psychological distress. RESULTS: Of the 8850 anesthesiologists from the 218 institutions who were invited to participate, 6331 (74.93%) completed the surveys and were included in the analysis. A total of 52.7% (95% confidence interval [CI], 51.5-53.9) met the criteria for burnout. Depression, anxiety, and PTSD were positively associated with burnout. After pooled multivariate analysis adjusting for potential confounding factors, among the COVID-19 exposure parameters, redeployment outside normal professional boundaries remained associated with an increased risk of burnout (odds ratio, 0.84; 95% CI, 0.72-0.92; P = .039). Higher perceived institutional support and resilience could act as protective factors against burnout. CONCLUSIONS: The impact of the COVID-19 epidemic on the psychological well-being of anesthesiologists still exists more than 1 year after the outbreak. Building better institutional support and cultivating stronger resilience may be helpful future intervention measures.

RESUMEN

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.

RESUMEN

Objective Airway-related patient safety incident (PSI) has always been the top concern of anesthesiologists because this type of incidents could severely threaten patient safety if not treated immediately and properly. This study intends to reveal the composition, prognosis, and to identify risk factors for airway related incidents reported by anesthesiologists. Methods All airway related PSIs reported by anesthesiologists in a Chinese academic hospital between September 2009 and May 2022 were collected from the PSI reporting system. Patients with airway incidents reported were matched 1:1 with controls based on sex and type of surgery. Univariable and multivariable analysis were performed to find risk factors associated with airway incident occurrence, and to evaluate influence of airway PSIs on patient prognosis. Results Among 1,038 PSIs voluntarily reported by anesthesiologists during the study period, 281 cases (27.1%) were airway-related incidents, with an overall reporting incidence of 4.74 per 10,000 among 592,884 anesthesia care episodes. Only ASA physical status was found to be significant independent predictor of these airway PSIs (P = 0.020). Patients with airway PSIs reported had longer extubation time (0.72 ± 1.56 d vs. 0.16 ± 0.77 d, 95%CI: 0.29 to 0.82, P < 0.001), longer ICU length of stay (LOS) (1.63 ± 5.71 d vs. 0.19 ± 0.84 d, 95%CI: 0.57 to 2.32, P= 0.001), longer post operative LOS (10.56 ± 13.09 d vs. 7.59 ± 10.76 d, 95%CI: 0.41 to 5.53, P = 0.023), and longer total in-hospital LOS (14.99 ± 15.18 d vs. 11.62 ± 11.88 d, 95%CI: 0.46 to 6.27,P = 0.024). Conclusions This single-center retrospective case-control study describes the composition of airway-related PSIs reported by anesthesiologists within thirteen years. Airway incidents might influence patient prognosis by elongating extubation time and LOS. Airway PSI data were worth analyzing to improve patient safety.

RESUMEN

Background Ultrasound-guided continuous thoracic paravertebral block can provide pain-relieving and opioid-sparing effects in patients receiving open hepatectomy. We hypothesize that these effects may improve the quality of recovery (QoR) after open hepatectomy. Methods Seventy-six patients undergoing open hepatectomy were randomized to receive a continuous thoracic paravertebral block with ropivacaine (CTPVB group) or normal saline (control group). All patients received patient-controlled intravenous analgesia with morphine postoperatively for 48 hours. The primary outcome was the global Chinese 15-item Quality of Recovery score on postoperative day 7, which was statistically analyzed using Student's t-test. Results Thirty-six patients in the CTPVB group and 37 in the control group completed the study. Compared to the control group, the CTPVB group had significantly increased global Chinese 15-item Quality of Recovery scores (133.14 ± 12.97 vs. 122.62 ± 14.89, P = 0.002) on postoperative day 7. Postoperative pain scores and cumulative morphine consumption were significantly lower for up to 8 and 48 hours (P < 0.05; P = 0.002), respectively, in the CTPVB group. Conclusion Perioperative CTPVB markably promotes patient's QoR after open hepatectomy with a profound analgesic effect in the early postoperative period.

RESUMEN

Objective To develop a risk prediction model combining pre/intraoperative risk factors and intraoperative vital signs for postoperative healthcare-associated infection(HAI)based on deep learning. Methods We carried out a retrospective study based on two randomized controlled trials(NCT02715076,ChiCTR-IPR-17011099).The patients who underwent elective radical resection of advanced digestive system tumor were included in this study.The primary outcome was HAI within 30 days after surgery.Logistic regression analysis and long short-term memory(LSTM)model based on iteratively occluding sections of the input were used for feature selection.The risk prediction model for postoperative HAI was developed based on deep learning,combining the selected pre/intraoperative risk factors and intraoperative vital signs,and was evaluated by comparison with other models.Finally,we adopted the simulated annealing algorithm to simulatively adjust the vital signs during surgery,trying to explore the adjustment system that can reduce the risk of HAI. Results A total of 839 patients were included in this study,of which 112(13.3%)developed HAI within 30 days after surgery.The selected pre/intraoperative risk factors included neoadjuvant chemotherapy,parenteral nutrition,esophagectomy,gastrectomy,colorectal resection,pancreatoduodenectomy,hepatic resection,intraoperative blood loss>500 ml,and anesthesia time>4 h.The intraoperative vital signs significantly associated with HAI were in an order of heart rate>core body temperature>systolic blood pressure>diastolic blood pressure.Compared with multivariable Logistic regression model,random forest model,and LSTM model including vital signs only,this deep learning-based prediction model performed best(ACC=0.733,F1=0.237,AUC=0.728).The simulation via simulated annealing algorithm reduced the incidence of postoperative HAI.Moreover,the incidence decreased most in the case of reducing the initial annealing temperature and choosing the last 20% of surgery procedure. Conclusions This study developed a risk prediction model for postoperative HAI based on deep learning,which combined pre/intraoperative risk factors and intraoperative basic vital signs.Using simulated annealing algorithm to adjust intraoperative vital signs could reduce the incidence of postoperative HAI to some extent.

RESUMEN

Objective To reveal the incidence,mortality,and risk factors of bleeding-related perioperative cardiac arrest(POCA). Methods We carried out a single-center retrospective case-control study which enrolled all the POCA cases reported from January 2010 to September 2020 in the patient safety incident reporting system of Peking Union Medical College Hospital.For the screening of risk factors,the patients were respectively assigned into the POCA group and the control group at a ratio of 1∶3 according to the same sex,age,American Society of Anesthesiologists(ASA)physical status,and type of surgery in the same month.Potential risk factors for POCA were first selected by univariate analysis.The significant risk factors were then checked based on the clinical experience and further included in the multivariate Logistic regression model. Results Totally 16 bleeding-related POCA cases were collected from the patient safety incident reporting system among the study period,with an overall incidence of 0.36/10 000.The blood loss volume of POCA group and control group was(7 037.50±5 477.70)ml and(375.63±675.14)ml,respectively(P<0.001),and 14(87.5%)patients suffering from bleeding-related POCA died within three days after anesthesia.According to the univariate analysis,patients' body mass index[(21.79±3.57)kg/m2 vs.(24.26±3.91)kg/m2,P=0.043],hemoglobin level[(113.44±31.08)g/L vs.(131.75±19.70)g/L,P=0.039],and alanine aminotransferase level[(17.31±7.73)U/L vs.(26.91±24.73)U/L,P=0.022]were significantly lower in the POCA group than in the control group.Further Logistic regression analysis showed that smaller body mass index and lower preoperative hemoglobin level were independently associated with the occurrence of bleeding-related POCA. Conclusions Bleeding-related POCA rarely occurred but had high mortality.Adequate precautions should be taken for the patients who are to receive surgeries with high risk of intraoperative massive bleeding.Elevating preoperative hemoglobin level might decrease the incidence of bleeding-related POCA.

RESUMEN

Objective To validate the performance of the model for predicting the risk of intraoperative hypothermia.Methods This observational prospective study enrolled the adult patients who were of American Society of Anesthesiologists Ⅰ-Ⅲ and underwent elective surgery with general anesthesia in Peking Union Medical College Hospital,Beijing Hospital,and Xuanwu Hospital of Capital Medical University from October 2019 to August 2021.The risk prediction model of intraoperative hypothermia was used to calculate the predictors score of each patient.The body temperature of each patient was monitored throughout the perioperative period,and perioperative temperature management were entirely at the discretion of the anesthesiologists.The area under the receiver operating characteristic curve(AUC),Hosmer-Lemeshow goodness-of-fit test,and Brier score were employed to evaluate the prediction performance of the model.Results Of the 472 participants included in this study,141(29.9%)developed intraoperative hypothermia and 124(26.3%)received intraoperative active warming.For predicting intraoperative hypothermia in the overall cohort,the model demonstrated good discrimination capacity with an AUC of 0.729(95% CI=0.680-0.777),adequate calibration(Hosmer-Lemeshow χ2=3.143,P=0.925),and good overall performance(Brier score of 0.34).For the patients with passive warming only,the model showed good discrimination(AUC=0.756;95% CI=0.704-0.808),good calibration(Hosmer-Lemeshow χ2=7.457,P=0.488),and the Brier score of 0.29.For the patients with active warming,the model presented the AUC of 0.747(95% CI=0.632-0.863),Hosmer-Lemeshow χ2 of 4.754(P=0.783)and the Brier score of 0.47.Furthermore,we stratified the risk scores as low,moderate and high risk groups,in which the incidence of intraoperative hypothermia was 14.4%(95% CI=9.6%-19.1%),36.7%(95% CI=29.9%-43.5%),and 58.2%(95% CI=46.1%-70.3%),respectively.The differences between the three groups were statistically significant(χ2=54.112,P<0.001).Conclusion The intraoperative hypothermia prediction model demonstrates good overall differentiation capacity and has good prediction performance for the patients with or without active warming.

RESUMEN

BACKGROUND: Elderly patients with acute myeloid leukemia (AML) can be treated with intensive therapy, low-intensity therapy, or best supportive care. Medical decision-making might be affected by physicians' occupational and non-occupational factors. OBJECTIVE: To explore the impact of physicians' personalities and behavioral traits on treatment-related decision-making for elderly AML patients. DESIGN: A nationwide cross-sectional survey. PARTICIPANTS: Hematologists in mainland China (N = 529; response rate 64.5%). MAIN MEASURES: The medical decision-making for elderly AML patients was evaluated using 6 clinical vignettes. Hematologists' attitudes toward risk and uncertainty, Big Five personality traits, and decision-making styles were assessed using binary lottery choices and well-recognized self-report inventories. KEY RESULTS: The resulting binary regression model in predicting treatment intensity contained professional title group (OR = 0.012, 95% CI 0.001 to 0.136, P < 0.001), conscientiousness (OR = 0.336, 95% CI 0.121 to 0.932, P = 0.036), extraversion (OR = 0.403, 95% CI 0.166 to 0.974, P = 0.044), conscientiousness by title group (OR = 2.009, 95% CI 1.100 to 3.667, P = 0.023), and extraversion by title group (OR = 1.627, 95% CI 0.965 to 2.743, P = 0.068) as predictors of therapy intensity preference. Junior physicians with a higher level of extraversion (mean difference = 0.27; 95% CI 0.07 to 0.45; P = 0.009) or conscientiousness (mean difference = 0.19; 95% CI 0.01 to 0.36; P = 0.028) tended to prescribe more intensive therapy. Meanwhile, no significant correlation was found between physicians' personalities or behavioral traits and treatment-related decision-making in senior physicians. CONCLUSIONS: Physicians' personalities contribute to treatment-related decision-making for elderly AML patients, depending on the professional titles. More extravert or conscientious attending physicians tended to prescribe more intensive therapy. Meanwhile, the decisions made by chief and associate chief physicians were not impacted by their personal traits. Junior physicians should be aware of such potential influence when making medical decisions.

RESUMEN

BACKGROUND: This systematic review and meta-analysis aims to evaluate efficacy and safety of endoscopic treatment for the non-polypoid dysplasia in patients with long-standing IBD. METHODS: Medline, Embase, Cochrane, and clinicaltrials.gov registry were comprehensively searched. Pooled estimates of curative, R0, en-bloc resection rates, CRC, metachronous dysplasia, and local recurrence rates were calculated. Subgroup analysis according to areas, lesion size, endoscopic resection techniques, and grades of dysplasia were conducted. Data synthesis was completed in R using the package "meta". RESULTS: Of the 973 studies initially identified, 7 met the inclusion/exclusion criteria. These were all single-arm cohorts and included a total of 202 patients with IBD and non-polypoid dysplasia. The combined R0 and en-bloc resection rate were 0.70 (95% CI 0.55-0.81) and 0.86 (95% CI 0.65-0.95), respectively, with a recurrence rate of 0.08 (95% CI 0.05-0.13). CRC and metachronous dysplasia incidences were pooled as 32.53 (95% CI 12.21-86.67) and 90.24 (95% CI 44.91-181.33) per 1000 patient years. CONCLUSIONS: Non-polypoid dysplasia associated with IBD can be resected endoscopically, especially by ESD. However, these patients have higher CRC and metachronous dysplasia incidence rates than patients with polypoid dysplasia, indicating a closer endoscopic surveillance.

RESUMEN

Objective Burnout is a triad of emotional exhaustion, depersonalization, and reduced personal accomplishment resulting from job stress. Although with distinct regional and cultural characteristics, burnout among anesthesiologists in the Tibet has not been described. This study aimed to explore the prevalence of burnout among anesthesiologists in Tibet and its associated factors. Methods A cross-sectional survey was conducted in Tibet, China, with an anonymous questionnaire. Social-demographic characteristics, work status, three dimensions of burnout assessed by the Maslach Burnout Inventory-Human Service Survey were collected and analyzed. Results A total of 133 individuals from 17 hospitals completed the survey from March to June 2018. The prevalence of moderate- to high-level of emotional exhaustion, depersonalization, and burnout in personal accomplishment was 65.4% (95%CI, 57.0%-72.9%), 66.9% (95%CI, 58.5%-74.3%), and 83.5% (95%CI, 76.2%-88.8%), respectively. An annual caseload ≥500, frequent overtime work and fair to poor sleep quality were significantly associated with a higher level of emotional exhaustion ( P<0.001,P=0.001, and P<0.0001, respectively). 5-9 years in anesthesiology experience was significantly associated with a high level of emotional exhaustion and depersonalization (P=0.002 and P=0.003, respectively). Conclusions More than half of anesthesiologists working in Tibet experience a moderate- to high- level of burnout in at least one dimensional scale. Anesthesiologists having 5-9 years of experience are more prone to emotional exhaustion and depersonalization. Efforts to decrease burnout through reducing the working load and raising the social recognition of anesthesiologists in Tibet should be considered.

RESUMEN

Objective To investigate the risk factors for patients using intraoperative vasopressor infusions during carotid body tumor(CBT)excision.Patients' mean arterial pressure(MAP)and heart rate(HR)fluctuations as well as their requirements for vasoactive agents during surgery were assessed. Methods The patients receiving CBT excision in Peking Union Medical College Hospital from May 1,2013 to July 31,2017 were included for a retrospective cohort study.The potential factors of intraoperative requirement for vasopressor infusions were investigated using univariate analysis and Logistic multivariate analysis.Furthermore,the relationships of Shamblin types of CBT with intraoperative MAP/HR fluctuations and requirements for vasoactive agents were analyzed. Results A total of 108 patients with 116 CBTs were included.Univariate analysis revealed that maximum tumor diameter >4 cm,intraoperative internal carotid artery injury,internal carotid artery reconstruction,malignant pathology,advanced Shamblin types(type Ⅱ and Ⅲ),estimated blood loss ≥400 ml,and operation duration >4 hours were associated with intraoperative requirements for vasopressor infusions.Logistic analysis showed that Shamblin type Ⅲ(OR=2.286,95% CI=1.324-14.926,P=0.016)and operation duration >4 hours(OR=3.874,95% CI=1.020-14.623,P=0.046)were risk factors for intraoperative requirements for vasopressor infusions during CBT surgery.In addition,Shamblin type Ⅲ was associated with intraoperative abnormal HR elevation and requirements for vasopressors.Conclusions Shamblin type Ⅲ and operation duration>4 hours are risk factors for intraoperative requirements of patients for using vasopressor infusions during CBT surgery.Shamblin type Ⅲ is associated with intraoperative abnormal HR elevation and requirements for vasopressors.

RESUMEN

Objectives Transmuscular quadratus lumborum block (TQLB) may provide postoperative analgesia in patients undergoing intraperitoneal surgeries. The purpose of this study was to examine the potential efficacy of TQLB among patients undergoing retroperitoneal procedures, such as the laparoscopic partial nephrectomy (LPN). Methods This prospective, randomized, controlled study was conducted from August 2017 to November 2018 at Peking Union Medical College Hospital (Beijing, China). Patients who were scheduled for a LPN, aged 18-70 years old with an ASA physical status score of I - II were randomly assigned to receive either TQLB with 0.6 ml/kg of 0.5% ropivacaine plus general anesthesia (TQLB group) or general anesthesia alone (control group). Patient-controlled intravenous analgesia with morphine was initiated immediately upon surgery completion. The primary outcome was the cumulative consumption of morphine within 8 h after surgery. The secondary outcome included postoperative consumptions of morphine at other time points, pain score at rest and during activity, postoperative nausea and vomitting (PONV), and recovery related parameters. Results Totally 30 patients per group were recruited in the study. The 8 h consumption of morphine was lower in the TQLB group than in the control group (median, 0.023 mg/kg vs. 0.068 mg/kg, U=207.5, P<0.001). No significant differences were observed in postoperative pain scores between the two groups. Patients in the TQLB group had fewer episodes of PONV (20% vs. 47%, χ2=4.8, P=0.028) in the first 24 h after surgery and higher scores for quality of recovery (mean, 138.6 vs. 131.9, t=-2.164, P=0.035) 120 h after surgery than the controls. Conclusions TQLB resulted in an opioid-sparing effect during the early postoperative period following LPN, as well as a lower incidence of PONV and improved quality of recovery.

RESUMEN

Objective To identify the possible factors that may influence the success and the complications of ultrasound-guided out-of-plane radial arterial cannulation. Methods Multivariate Logistic regression analysis was used to analyze the clinical data of 131 patients undergoing elective surgery and ultrasound-guided out-of-plane radial artery cannulation,dynamic needle tip positioning(DNTP) technique or angular distance(AD) technique and to find out the factors associated with the one-attempt success rate,overall success rate,posterior arterial wall perforation,and local hematoma. Results The depth of the anterior arterial wall≥3 mm was the factor associated with posterior arterial wall perforation(OR=0.314,95%CI:0.143-0.691,P=0.004) and local hematoma(OR=0.250,95%CI:0.107-0.585,P=0.001).The use of DNTP method was significantly associated with posterior arterial wall perforation(OR=0.303,95%CI:0.138-0.667,P=0.003). Conclusions During ultrasound-guided out-of-plane radial cannulation,puncture at the arterial anterior wall sites with a depth of≥3 mm can reduce the incidence of posterior arterial wall perforation and local hematoma.Compared with AD,DNTP can lower the incidence of posterior arterial wall perforation.

RESUMEN

Objective Identification of the risk factors for extraordinary hidden blood loss (HBL) could clarify the underlying causes and provide more appropriate management. This study aims to identify the predictors of HBL in spinal surgery.Methods Medical records were retrospectively retrieved to collect the data of patients who undergoing posterior thoracic and lumbar fusion surgery or scoliosis surgery. Demographic information, perioperative visible blood loss volume, as well as laboratory results were recorded. The patients receiving fusion surgery or scoliosis surgery were further divided into the HBL positive subgroup and the HBL negative subgroup. Differences in the variables between the groups were then analyzed. Binary logistic regression analysis was performed to determine independent risk factors associated with HBL.Results For patients undergoing posterior spinal surgery, the independent risk factors associated with HBL were autologous transfusion (for fusion surgery P=0.011, OR: 2.627, 95%CI: 1.574-2.782; for scoliosis surgery P<0.001, OR: 2.268, 95%CI: 2.143-2.504) and allogeneic transfusion (for fusion surgeryP<0.001, OR: 6.487, 95%CI: 2.349-17.915; for scoliosis surgery P<0.001, OR: 3.636, 95%CI: 2.389-5.231).Conclusions Intraoperative blood transfusion might be an early-warning indicator for perioperative HBL.

RESUMEN

Objective To evaluate the application of adding ondansetron in morphine intravenous analgesia pump for prevention of postoperative nausea and vomiting(PONV)in women. Methods Data of surgical female inpatients who received general anesthesia and postoperative intravenous analgesia with morphine in our center from January 1st,2013 to December 31st,2014 were retrospectively analyzed. Based on whether ondansetron was added,patients were divided into the observation group(n=834) and the control group(n=856). Outcome variables including morphine consumption,visual analogue scale(VAS) score,nausea score,and total times of vomiting within 48 hours after surgery were collected and compared. Results Age(t=0.432,P=0.665),morphine consumption during the first post-operative day(t=0.599,P=0.548) and during the second post-operative day(t=0.236,P=0.813),maximum VAS score of postoperative pain during movement during the first post-operative day [3(2,4) vs. 3(2,5);Z=1.850,P=0.064] and at rest during the second post-operative day [0(0,1) vs. 0(0,1);Z=1.511,P=0.131] were not significantly different between two groups. While the maximum VAS score of postoperative pain at rest during the first post-operative day [0(0,2) vs.0(0,2);Z=2.435,P=0.015] and during movement during the second post-operative day [3(1,3)vs.3(2,4);Z=3.445,P=0.001] were significantly different between two groups. The maximum score of postoperative nausea(χ2=9.810,P=0.020) and cumulative frequency of postoperative vomiting(Z=3.726,P=0.002)in the observation group were significantly lower than those in the control group during the first post-operative day;however,there was no significant difference during the second post-operative day(χ2=5.017,P=0.170;Z=0.000,P=1.000). Logistic regression analysis showed that adding ondansetron in morphine intravenous analgesia pump was an independent influencing factor of reduced postoperative nausea. The probability of nausea during the first post-operative day was 0.781 time(P=0.015)of that in the control group and 0.736 time(P=0.030)during the second post-operative day. Conclusion Adding ondansetron in morphine intravenous analgesia pump may reduce PONV in women.

RESUMEN

OBJECTIVE: To systematically evaluate the incidence of liver injury in multi-drug resistant tuberculosis (MDR-TB) patients with the treatment of second-line anti-TB drugs. METHODS: Medline (January 1, 1966 to March 1, 2014), Embase (January 1, 1974 to March 1, 2014) and the Cochrane library (January 1, 1993 to March 1, 2014) with four Chinese databases including VIP (January 1, 1989 to March 1, 2014), CBMDisc (January 1, 1978 to March 1, 2014), CNKI (January 1, 1994 to March 1, 2014)and Wanfang (January 1, 1998 to March 1, 2014), were systematically searched with the keywords including "Tuberculosis", "multidrug-resistant", "MDR-TB", "side effect", "adverse", "safety" and "tolerability" for the follow-up studies of MDR-TB patients with liver injury during the treatment of second-line anti-TB drugs. The relevant information was extracted and the data were analyzed using the random-effects model. Subgroup and sensitivity analyses were performed based on the diagnostic criteria, study population, study design, history of anti-TB treatment and treatment length. RESULTS: A total of 26 articles with 3 875 MDR-TB patients were included, of which 373 patients developed liver injury, and the weighed combined incidence of liver injury was 7.7%(95%CI:5.5%-10.8%). There was some heterogeneity among the studies. Subgroup analyses showed that the incidence of liver injury was higher in groups with treatment length ≥ 18 months and non-Asian populations, but there was no significant difference between the groups (P>0.05). Among the 26 articles, only nine of them reported the diagnostic criteria of liver injury, while the criteria were not uniform. CONCLUSION: The incidence of liver injury during the treatment of second-line anti-TB drug in MDR-TB patients was high, and the diagnostic criteria were not uniform. We should pay attention to the prevention and treatment of liver injury, and develop standard diagnostic criteria for it.

RESUMEN

OBJECTIVES: Colorectal cancer (CRC) is highly prevalent worldwide and is a leading cause of cancer-related death. Probiotics, prebiotics, and synbiotics have recently attracted attention as preventive measures against colorectal neoplasms. We aimed to analyze the findings of randomized controlled trials (RCTs) on the effects of probiotics, prebiotics, and synbiotics in patients at a high risk of CRC, outlining the challenges and future prospects of using probiotics to prevent colorectal tumors and providing evidence for clinical physicians in particular. METHODS: PubMed, EMBASE, and the Cochrane Library databases were searched for relevant studies published up to January 7, 2022. RCTs conducted on populations with a high risk of CRC who received probiotics, prebiotics or synbiotics in comparison with placebo, candidate agent or no treatment were included. The primary outcome was the incidence or recurrence of any colorectal neoplasms. Additional outcomes included their effects on the diversity of gut microbiota and relevant inflammatory biomarkers. Safety outcomes were also analyzed. Two authors independently screened and selected studies based on pre-specified eligible criteria, performed data extraction and risk-of-bias assessment independently. RESULTS: Nine RCTs were included in the systematic review and meta-analysis. Probiotic supplementation significantly reduced adenoma incidence, but no significant benefit was observed in CRC incidence. Additionally, probiotics modulated gut microbiota and inflammatory biomarkers. CONCLUSION: Probiotics may have beneficial effects in the prevention of CRC. More RCTs with larger sample sizes are warranted to further confirm these findings.

RESUMEN

OBJECTIVE: To assess the efficacy and safety of parenterally administered Shenqi Fuzheng for heart failure. METHOD: We searched for all clinical studies, up to February 2013, of parenterally administered Shenqi Fuzheng in the Cochrane library, Medline, EMbase, CBM, CNKI, VIP and Wanfang. Quality assessment and information extraction was completed and screened by two independent reviewers. The quality of the included studies was evaluated according to the Cochrane collaboration's tool for assessing risk of bias and allocation concealment. Revman 5. 2. 4 software was used for data analysis. RESULT: A total of 21 randomized controlled trials were included in this systematic review, all of them were of low quality. Meta-analysis showed that the group receiving parenterally administered Shenqi Fuzheng in addition to conventional treatment had better therapeutic effectiveness rates than the conventional treatment group [OR = 3.91, 95% Cl (2.63, 5.83)], with enhanced LVEF [MD = 0.08, 95% Cl (0.05, 0.12)], SV [MD = 9.42, 95% Cl (6.61, 12.22)], CI [MD = 0.60, 95% Cl (0.46,0.73)], CO [MD = 0.98, 95% Cl (0.61, 1.36)], reduced BNP [MD = -139.05, 95% Cl (-211.08, - 67.02)]. The ADR/ADE information of parenterally administered Shenqi Fuzheng in all studies showed that the symptoms of ADR/ADE were mild. CONCLUSION: Conclusions from this review may have a high risk of bias due to the low quality of thestudies. Hence, reliable conclusions cannot be drawn about the efficacy of parenterally administered Shenqi Fuzheng in the treatment of heart failure. More trials of high quality are required.
