The comparison of ketamine with tramadol for postoperative pain relief on children following adenotonsillectomy or tonsillectomy: A meta-analysis of randomized controlled trials

Introduction:The comparison of ketamine with tramadol for pain control remains controversial in pediatric adenotonsillectomy or tonsillectomy. We conduct a systematic review and meta-analysis to explore the efficacy of ketamine vs tramadol for pain relief in children following adenotonsillectomy or tonsillectomy.Methods:We have searched PubMed, EMbase, Web of science, EBSCO, and Cochrane library databases through October 2019 for randomized controlled trials (RCTs) assessing the effect of ketamine vs tramadol for pediatric adenotonsillectomy or tonsillectomy. This meta-analysis is performed using the random-effects model.Results:Six RCTs are included in the meta-analysis. Overall, compared to ketamine group for pediatric adenotonsillectomy or tonsillectomy, tramadol is associated with substantially lower CHEOPS at 1 h (SMD = 1.56; 95% CI = 0.20–2.92; P = .02; low quality) and longer first time of additional pain medication (SMD = −0.47; 95% CI = −0.74 to −0.19; P = .0008; low quality), but demonstrates no obvious effect on CHEOPS at 6 h (SMD = 0.51; 95% CI = −1.17 to 2.19; P = .55; low quality), sedation scale at 1 h (SMD = −0.80; 95% CI = −3.07 to 1.48; P = .49; low quality) or additional pain medication (RR = 1.31; 95% CI = 0.85–2.02; P = .23; moderate quality).Conclusions:Tramadol may be better to alleviate the postoperative pain after pediatric adenotonsillectomy or tonsillectomy.     

Influence of ketamine versus fentanyl on pain relief for pediatric orthopedic emergencies: A meta-analysis of randomized controlled studies

Introduction:The comparison of ketamine with fentanyl for pain control of pediatric orthopedic emergencies remains controversial. We conduct a systematic review and meta-analysis to explore the influence of ketamine versus fentanyl on pain management among pediatric orthopedic emergencies.Methods:We have searched PubMed, EMbase, Web of science, EBSCO, and Cochrane library databases through September 2020 for randomized controlled trials assessing the effect of ketamine versus fentanyl on pain management for pediatric orthopedic emergencies.Results:Five randomized controlled trials are included in the meta-analysis. Overall, compared with fentanyl for pediatric orthopedic emergencies, ketamine led to similar change in pain scores at 15 to 20 minutes (standard mean difference = -0.05; 95% confidence interval [CI] = -0.38 to 0.28; P = .77) and 30 minutes (standard mean difference = 0.11; 95% CI = -0.20 to 0.42; P = .49), as well as rescue analgesia (RR = 0.90; 95% CI = 0.54 to 1.51; P = .69), but revealed the increase in nausea/vomiting (RR = 2.65; 95% CI = 1.13 to 6.18; P = .02) and dizziness (RR = 3.83; 95% CI = 1.38 to 10.60; P = .01).Conclusions:Ketamine may be similar to fentanyl in terms of the analgesic efficacy for pediatric orthopedic emergencies.     

Rectal chloral hydrate sedation for computed tomography in young children with head trauma

Children evaluated in the emergency department for head trauma often undergo computed tomography (CT), with some uncooperative children requiring pharmacological sedation. Chloral hydrate (CH) is a sedative that has been widely used, but its rectal use for child sedation after head trauma has rarely been studied. The objective of this study was to document the safety and efficacy of rectal CH sedation for cranial CT in young children.We retrospectively studied all the children with head trauma who received rectal CH sedation for CT in the emergency department from 2016 to 2019. CH was administered rectally at a dose of 50 mg/kg body weight. When sedation was achieved, CT scanning was performed, and the children were monitored until recovery. The sedative safety and efficacy were analyzed.A total of 135 children were enrolled in the study group, and the mean age was 16.05 months. The mean onset time was 16.41 minutes. Successful sedation occurred in 97.0% of children. The mean recovery time was 71.59 minutes. All of the vital signs were within normal limits after sedation, except 1 (0.7%) with transient hypoxia. There was no drug-related vomiting reaction in the study group. Adverse effects occurred in 11 patients (8.1%), but all recovered completely. Compared with oral CH sedation, rectal CH sedation was associated with quicker onset (P < .01), higher success rate (P < .01), and lower adverse event rate (P < .01).Rectal CH sedation can be a safe and effective method for CT imaging of young children with head trauma in the emergency department.     

D-Dimer Can Serve as a Prognostic and Predictive Biomarker for Metastatic Gastric Cancer Treated by Chemotherapy

Systemic activation of hemostasis and thrombosis has been implicated in tumor progression and metastasis. D-dimer has been used as an indicator for the thrombosis. Here, we investigated the role of the activation of coagulation in patients with metastatic gastric cancer by measuring D-dimer level.We conducted an observation study of 46 metastatic gastric cancer patients who received palliative chemotherapy (CTx). D-dimer levels were assessed before CTx and at the first response evaluation after CTx.The overall survival (OS) of patients with pretreatment D-dimer levels <1.5 μg/mL was significantly longer than that of patients with D-dimer levels ≥1.5 μg/mL (22.0 vs 7.9 months, P = 0.019). At the first response evaluation, the mean level of D-dimer was significantly decreased by 2.11 μg/mL in patients either with partial response or stable disease (P = 0.011) whereas the mean level of D-dimer, although the difference did not reach statistical significance, was increased by 2.46 μg/mL in patients with progressive disease. In addition, the OS of patients with D-dimer levels <1.0 μg/mL at the first response evaluation was significantly longer than that of patients with D-dimer levels ≥1.0 μg/mL (22.0 vs 7.0 months, P = 0.009). The lower D-dimer levels (<1.0 μg/mL) at the first response evaluation after CTx was independent predictive factor for better survival in multivariate analysis (P = 0.037).This study suggests that D-dimer levels may serve as a biomarker for response to CTx and OS in patients with metastatic gastric cancer.     

Comparison of thyroid-stimulating hormone levels in adolescents with schizophrenia,bipolar disorder,unipolar depression,conduct disorders,and hyperkinetic disorders

The aim of this study was to retrospectively compare values of thyroid-stimulating hormone (TSH) in adolescent patients diagnosed with schizophrenia, bipolar disorder, unipolar depression (UNI-DEP), conduct disorders (CD), and hyperkinetic disorders.The research involved 1122 patients (718 women, 64%); aged 12 to 18 hospitalized in the Department of Adolescent Psychiatry, Medical University of Lodz. We analyzed TSH levels in the whole study population and compared it between the above-mentioned subgroups of diagnoses.Mean serum TSH concentration in the studied population (n = 1122) was 2.06 μIU/mL. The values of percentiles were as follows: 2.5th – 0.53 μIU/mL, 10th – 0.89 μIU/mL, 25th – 1.31 μIU/mL, 50th – 1.9 μIU/mL, 75th – 2.6 μIU/mL, 90th – 3.43 μIU/mL, 97.5th – 4.72 μIU/mL. TSH values were negatively correlated with patients’ age (P = .00001). Patients with bipolar depression had higher TSH levels than patients with CD (P = .002). Also, when male and female groups were examined separately we found that female patients with UNI-DEP and bipolar disorder had higher TSH levels than female patients with CD (P = .001; P = .001).Our results confirm that there may be a higher prevalence of thyroid dysfunctions in bipolar and UNI-DEP subgroups among adolescents and that it is worthy to consider some kind of interventions regarding thyroid function in depressed individuals.     

Absence of association between pretransplant serum soluble programmed death protein-1 level and prognosis following living donor liver transplantation in patients with hepatocellular carcinoma

Programmed death protein 1 (PD-1) pathway is one of the most critical mechanisms in tumor biology of hepatocellular carcinoma (HCC). The study aimed to assess the prognostic influence of pretransplant serum soluble PD-1 (sPD-1) in patients undergoing liver transplantation for treatment of HCC.Data from 229 patients with HCC who underwent living donor liver transplantation between January 2010 and December 2015 were retrospectively evaluated. Stored serum samples were used to measure sPD-1 concentrations.Overall survival (OS) and disease-free survival (DFS) rates were 94.3% and 74.5% at 1 year; 78.2% and 59.2% at 3 years; and 75.4% and 55.5% at 5 years, respectively. Prognostic analysis using pretransplant serum sPD-1 with a cut-off of 93.6 μg/mL (median value of the study cohort) did not have significant prognostic influence on OS (P = .69) and DFS (P = .26). Prognostic analysis using sPD-1 with a cut-off of 300 μg/mL showed similar OS (P = .46) and marginally lower DFS (P = .070). Combination of Milan criteria and sPD-1 with a cutoff of 300 μg/mL showed similar outcomes of OS and DFS in patients within and beyond Milan criteria. Multivariate analysis revealed that only Milan criteria was an independent prognostic for OS and DFS, but pretransplant sPD1 with a cut-off of 300 μg/mL did not become a prognostic factor.The results of this study demonstrate that pretransplant serum sPD-1 did not show significant influences on post-transplant outcomes in patients with HCC. Further large-scale, multicenter studies are necessary to clarify the role of serum sPD-1 in liver transplantation recipients.     

Nurse-led exercise and cognitive-behavioral care against nurse-led usual care between and after chemotherapy cycles in Han Chinese women of ovarian cancer with moderate to severe levels of cancer-related fatigue: A retrospective analysis of the effectiveness

Women with ovarian cancer are reported to fatigue over time. Moderate to severe levels of cancer-related fatigue is fluent in Han Chinese patients with cancer. Comprehensive Cancer Network guidelines are recommending exercise and cognitive behavioral therapy to reduce cancer-related fatigue. Exercise is an easy, cost-effective, and non-pharmacological approach. The objective of the study was to evaluate the effectiveness of nurse-led exercise and cognitive-behavioral care against nurse-led usual care in Han Chinese women of ovarian cancer regarding cancer-related fatigue, depressive symptoms, and sleep quality.Han Chinese women with moderate to severe levels of cancer-related fatigue have received 30 minutes, 5 times/week nurse-led exercise and 60 min/week cognitive-behavioral care (EC cohort, n = 118) or nurse-led usual care regarding educations and recommendations only (UC cohort, n = 126) or have not received nurse-led exercise, cognitive-behavioral care, educations, and recommendations (NC cohort, n = 145) between and after chemotherapy cycles. The Piper Fatigue Scale, the Zung Self-rating Depression Scale, and Pittsburgh Sleep Quality Index questionnaires were evaluated at the start and the end of non-pharmacological treatment.At the end of treatment as compared to the start of treatment, only women of EC cohort had decrease Piper Fatigue Scale (5.40 ± 1.49/woman vs 6.06 ± 1.49/woman, P < .0001, q = 4.973) and Zung Self-rating Depression Scale score (48.67 ± 4.24/woman vs 49.93 ± 4.29/woman, P = .001, q = 3.449). Also, at the end of treatment, as compared to the start of treatment, only women of EC cohort have increased Pittsburgh Sleep Quality Index score (14.76 ± 2.18/woman vs 13.94 ± 2.90/woman, P = .045, q = 3.523). Only exercise and cognitive-behavioral care were successful in a decrease in the numbers of women with depression (the Mandarin Chinese version of the Zung Self-rating Depression Scale score >53, 32 vs 16, P = .015).Nurse-led exercise and cognitive-behavioral care can help Han Chinese women with ovarian cancer to decrease cancer-related fatigue and depression. Also, it can improve the quality of sleep.Evidence Level: 4.Technical Efficacy: Stage 5.     

Granulomas as the Most Useful Histopathological Feature in Distinguishing between Crohn's Disease and Intestinal Tuberculosis in Endoscopic Biopsy Specimens

The incidence of Crohn''s disease (CD) is increasing in Chinese populations in whom intestinal tuberculosis (ITB) is prevalent.This study aimed to identify differential diagnostic microscopic and endoscopic characteristics of CD from those of ITB.Patients with CD (N = 52) and patients with ITB (N = 16) diagnosed between 2010 and 2013 were identified. Specimens obtained via endoscopy were analyzed microscopically by a pathologist. The relationship between endoscopic appearance and histopathological features was analyzed. The χ² test, Fisher''s exact probability test, and the Mann-Whitney U test were used.Granulomas were present in 81.3% of ITB cases and in 67.3% of CD cases (P = 0.36). Granulomas in ITB cases were denser than those in CD cases (mean 5.29 ± 4.30 vs. 2.46 ± 3.50 granulomas per 10 low power fields; each low power field = 3.80 mm²; P = 0.005). Granulomas in ITB cases were larger (mean widest diameter, 508 ± 314 μm; range, 100–1100 μm) than those in CD cases (mean widest diameter, 253 ± 197 μm; range, 50–800 μm). Basal plasmacytosis was more common in CD cases than in ITB cases (77.0% vs. 37.5%, P = 0.000). Endoscopy findings such as longitudinal ulcer, aphthous ulcer, and cobblestone appearance were only seen in CD cases (34.6%, 21.2%, and 23.1%, respectively). Granulomas were detected in the majority of cases with longitudinal ulcers (88.9%). Basal plasmacytosis was exclusively detected in cases with longitudinal ulcer and a cobblestone appearance.Characteristics of granulomas maybe the most important distinguishing features between CD and ITB. However, the histopathological characteristics of both diseases may overlap on endoscopic biopsy specimens. An accurate diagnosis should be made that considers clinical, endoscopic features, and pathologic findings.     

Dexmedetomidine in Postoperative Analgesia in Patients Undergoing Hysterectomy: A CONSORT-Prospective,Randomized, Controlled Trial

Both dexmedetomidine and sufentanil modulate spinal analgesia by different mechanisms, and yet no human studies are available on their combination for analgesia during the first 72 hours after abdominal hysterectomy.This CONSORT-prospective, randomized, double-blinded, controlled trial sought to evaluate the safety and efficacy of the combination of dexmedetomidine and sufentanil in intravenous patient-controlled analgesia (PCA) for 72 hours after abdominal hysterectomy.Ninety women undergoing total abdominal hysterectomy were divided into 3 equal groups that received sufentanil (Group C; 0.02 μg/kg/h), sufentanil plus dexmedetomidine (Group D1; 0.02 μg/kg/h, each), or sufentanil (0.02 μg/kg/h) plus dexmedetomidine (0.05 μg/kg/h) (Group D2) for 72 hours after surgery in this double-blinded, randomized study. The primary outcome measure was the postoperative sufentanil consumption, whereas the secondary outcome measures were pain intensity (visual analogue scale), requirement of narcotic drugs during the operation, level of sedation, Bruggrmann comfort scale, and concerning adverse effects.The postoperative sufentanil consumption was significantly lower in Groups D1 and D2 than in Group C during the observation period (P < 0.05), but lower in Group D2 than in Group D1 at 24, 48, and 72 hours after surgery (P < 0.05). The heart rate after intubation and incision was lower in Groups D1 and D2 than in Group C (P < 0.05). On arrival at the recovery room, Groups D1 and D2 had lower mean blood pressure than Group C (P < 0.05). The intraoperative requirement of sevoflurane was 30% lesser in Groups D1 and D2 than in Group C. The sedation levels were greater in Groups D1 and D2 during the first hour (P < 0.05). Compared with Groups C and D1, Group D2 showed lower levels of the overall incidence of nausea and vomiting (P < 0.05).Among the tested PCA options, the addition of dexmedetomidine (0.05 μg/kg/h) and sufentanil (0.02 μg/kg/h) showed better analgesic effect and greater patient satisfaction without other clinically relevant side effects for patients undergoing hysterectomy during the first 72 hours after abdominal hysterectomy.     

Effectiveness of microperimetry in evaluating anti-vascular endothelial growth factor therapy for diabetic macular edema patients with relatively good vision: A retrospective observational study

No studies have evaluated the retinal sensitivity (RS) for diabetic macular edema (DME) patients with good vision. Therefore, this study aimed to determine the effectiveness of microperimetry in evaluating the effectiveness of anti-vascular endothelial growth factor (anti-VEGF) treatment for DME patients with relatively good vision.Twenty-seven eyes of 27 patients (mean age, 61.3 ± 11.2 years) with DME and decimal best-corrected visual acuity (BCVA) ≥0.6 were studied. All patients received 3 consecutive monthly injections of intravitreal anti-VEGF agents. The BCVA, central subfield macular thickness (CMT), and RS were evaluated by microperimetry (MAIA) within the 10 degree of the foveal center. To determine significant differences between the values, we used paired t tests.Patients were evaluated at baseline and 4 weeks after the third injection. The BCVA improved significantly from 0.18 ± 0.06 logarithm of the minimum angle of resolution (logMAR) units to 0.13 ± 0.13 logMAR units (P = .002; paired t test). The CMT decreased significantly from 464.3 ± 91.8 μm to 393.4 ± 129.0 μm (P = .005), and the RS also improved significantly from 21.8 ± 3.1 dB to 24.1 ± 2.8 dB at 4 weeks after treatment (P = .006). Among the patients with a decimal BCVA of 0.7 or better at baseline, there was no significant improvement in the BCVA (P = .28). However, the CMT decreased significantly from 479.5 ± 79.1 μm to 394.0 ± 99.8 μm at 4 weeks after treatment (P = .007). The RS also improved significantly from 22.0 ± 2.4 dB to 24.0 ± 3.1 dB at 4 weeks after treatment (P = .004).Measuring RS by microperimetry is a good option for evaluating the effectiveness of anti-VEGF treatment for DME patients with a relatively good BCVA.     

Safety and Efficacy of the Moderate Sedation During Flexible Bronchoscopic Procedure: A Systematic Review and Meta-Analysis of Randomized Controlled Trials

Moderate sedatives have been increasingly used to improve patient comfort during flexible bronchoscopy (FB). However, routine use of moderate sedation during FB is controversial because its efficacy and safety are not well established.This study aims to evaluate the efficacy and safety of moderate sedation during FB.A search was made of Medline, EMBASE, and the Cochrane Library to May 2014.Randomized controlled trials (RCTs) and quasi-RCTs were included.The main analysis was designed to examine the efficacy of moderate sedation during FB in sedation than no-sedation.The willingness to repeat FB was significantly more in sedation than no-sedation (odds ratio [OR] 2.30; 95% confidence interval [CI] 1.11–4.73; P = 0.02; I² = 22.5). The duration of FB was shorter in sedation group than no-sedation group (standardized mean difference [SMD] −0.21; 95% CI −0.38 to −0.03; P = 0.02; I² = 78.3%). Event of hypoxia was not significantly different between sedation and no-sedation groups (OR 0.86; 95% CI 0.42–1.73; P = 0.67; I² = 0%). The SpO₂ during procedure was not different between sedation and no-sedation groups (SMD −0.14; 95% CI −0.37 to 0.08; P = 0.21; I² = 49.9%). However, in subgroup analysis without supplemental oxygen, the SpO₂ was significantly lower in sedation than no-sedation group (SMD −0.45; 95% CI −0.78 to −0.11; P = 0.01; I² = 0.0%).According to this meta-analysis, moderate sedation in FB would be useful in patients who will require repeated bronchoscopies as well as safe in respiratory depression. To our knowledge, although the various sedative drugs are already used in the real field, this analysis was the first attempt to quantify objective results. We anticipate more definite and studies designed to elucidate standardized outcomes for moderate sedation in FB.     

Effect of Blood Cadmium Level on Mortality in Patients Undergoing Maintenance Hemodialysis

Previous studies of general populations indicated environmental exposure to low-level cadmium increases mortality. However, the effect of cadmium exposure on maintenance hemodialysis (MHD) patients is unclear.A total of 937 MHD patients from 3 centers in Taiwan were enrolled in this 36-month observational study. Patients were stratified by baseline blood cadmium level (BCL) into 3 groups: high BCL (>0.521 μg/L; n = 312), intermediate BCL (0.286−0.521 μg/L; n = 313), and low BCL (<0.286 μg/L; n = 312). The mortality rates and causes of death were analyzed.The analytic results demonstrated patients in the high BCL group had a significantly higher prevalence of malnutrition and inflammation than patients in the low and intermediate BCL groups. After 3 years of follow-up, 164 (17.5%) patients died and the major cause of death was cardiovascular disease. A Cox multivariate analysis indicated the high BCL group had increased hazard ratios (HRs) for all-cause mortality (HR = 1.72; 95% confidence interval [CI]: 1.14–2.63; P = 0.018), cardiovascular-related mortality (HR = 1.85; 95% CI: 1.09–3.23; P = 0.032), and infection-related mortality (HR = 2.27; 95% CI: 1.12–4.55; P = 0.035). A Cox multivariate analysis of MHD patients who never smoked (n = 767) indicated the high BCL group had increased HRs for all-cause mortality (HR = 1.67; 95% CI: 1.04–2.63; P = 0.048) and cardiovascular-related mortality (HR = 2.08; 95% CI: 1.08–4.00; P = 0.044).In conclusion, BCL is an important determinant of mortality in MHD patients. Therefore, MHD patients should avoid cadmium exposure as much as possible, such as tobacco smoking and eating cadmium-containing foods.     

Retinal Nerve Fiber Layer Thickness in Myopic,Emmetropic, and Hyperopic Children

The purpose of this study was to investigate the peripapillary retinal nerve fiber layer (RNFL) thickness in myopic, emmetropic, and hyperopic children using optical coherence tomography.Two-hundred one right eyes of subjects aged 4 to 18 years were divided into 3 groups based on their postcycloplegic spherical equivalent: myopes (<−1.0 D), emmetropes (≥−1.0 to ≤+1.0 D), and hyperopes (>+1.0 D). The RNFL was correlated with age, spherical equivalent, and axial length. The RNFL was compared between the 3 groups before and after age adjustment.The RNFL was thickest in the hyperopic group (107.2 ± 10.13 μm, n = 73), followed by the emmetropic group (102.5 ± 9.2 μm, n = 61), and then the myopic group (95.7 ± 10.3, n = 67) (all P < 0.0001). The myopic group (9.6 ± 3.9 years) was significantly older than the emmetropic (6.9 ± 2.7 years) and hyperopic (6.5 ± 1.9 years) groups (both P < 0.0001). When adjusted for age, myopes had a thinner RNFL than the other 2 groups (all P < 0.0001), but there was no RNFL thickness difference between the emmetropic and hyperopic groups (P > 0.05). A thinner RNFL was associated with an older age (r = −0.4, P < 0.0001), a more myopic spherical equivalent (r = 0.5, P < 0.0001), and a longer axial length (r = −0.4, P < 0.0001) on Pearson correlation analysis.The apparently thicker RNFL in hyperopic and emmetropic children was attributed to their younger age as compared with their myopic counterparts. When adjusted for age, only myopia was associated with a thinner RNFL, with emmetropic and hyperopic children having equal RNFL thicknesses. Advancing age, a more myopic spherical equivalent, and a longer axial length were associated with a thinner RNFL in children.     

Dexmedetomidine dosage in critically ill patients undergoing intraoperative wake-up test: A randomized controlled trial

Objective:The aim of this study was to find the optimum dosage of dexmedetomidine in Spinal Orthopedic Scoliosis Correction Surgery when used in combination with propofol and remifentanil in American Society of Anesthesiologists (ASA) III patients with severe scoliosis undergoing intraoperative wake-up test.Materials and methods:We selected a total of 60 ASA III ≤40 years old patients who underwent Spinal Orthopedic Scoliosis Correction Surgery (SOSCS) and randomized them into groups A, B, and C. Group A was administered 0.2 μg/(kg·h) of dexmedetomidine, group B 0.3 μg/(kg·h), and group C 0.4 μg/(kg·h). The main parameters monitored were: wake-up time; wake-up quality; adverse effects that occur while the patient is awake; postoperative awareness of intraoperative wake-up test; heart rate (HR); mean arterial pressure (MAP); and oxygen saturation (SpO₂). Values of these parameters were monitored at 7 timestamps separated by 5 minutes >30 minutes.Results:Group B had a higher MAP at 10 minutes before wake-up (P = .03) and at the moment of wake-up (P = .04) than group A. The Wake-up time of group A was 14.95 ± 7.42 minutes, group B was 14.7 ± 6.52 minutes, which was significantly shorter than that of group C 21.3 ± 10.02 minutes (P = .02). The wake-up quality was excellent. All other parameters had no significant statistical differences.Conclusion:Doses of 0.2 to 0.3 μg/(kg·h) have shorter wake-up time and fewer hemodynamic fluctuations compared to 0.4 μg/(kg·h).     

Selective Inflow Occlusion Technique Versus Intermittent Pringle Maneuver in Hepatectomy for Large Hepatocellular Carcinoma: A Retrospective Study

Selective inflow occlusion (SIO) maneuver preserved inflow of nontumorous liver and was supposed to protect liver function. This study aims to evaluate whether SIO maneuver is superior to Pringle maneuver in patients undergoing partial hepatectomy with large hepatocellular carcinomas (HCCs).Between January 2008 and May 2012, 656 patients underwent large HCC resections and were divided into 2 groups: intermittent Pringle maneuver (IP) group (n = 336) and SIO group (n = 320). Operative parameters, postoperative laboratory tests, and morbidity and mortality were analyzed.In comparison to the IP maneuver, the SIO maneuver significantly decreased intraoperative blood loss (473 vs 691 mL, P = 0.001) and transfusion rates (11.3% vs 28.6%, P = 0.006). The rate of major complication between the 2 groups was comparable (22.6% vs 18.8%, P = 0.541). Patients with moderate/severe cirrhosis, total bilirubin > 17 μmol/L, or HBV DNA> = 104 copy/mL in SIO group resulted in lower major complication rates.The SIO maneuver is a safe and effective technique for large HCC resections. In patients with moderate/severe cirrhosis, total bilirubin > 17 μmol/L, or HBV DNA> = 104 copy/mL, the SIO technique is preferentially recommended.     

Anaesthesia and ICU sedation with sevoflurane do not reduce myocardial injury in patients undergoing cardiac surgery: A randomized prospective study

Background:To evaluate the effect of anaesthesia and ICU sedation with sevoflurane to protect the myocardium against ischemia-reperfusion injury associated to cardiac surgery assessed by troponin release.Methods:We performed a prospective, open-label, randomized study in cardiac surgery with cardiopulmonary bypass. Patients were randomized to an algorithm-based intervention group and a control group. The main outcome was the perioperative kinetic of cardiac troponin I (cTnI). The secondary outcomes included composite endpoint, GDF-15 (macrophage inhibitory cytokine-1) value, arterial lactate levels, and the length of stay (LOS) in the ICU.Results:Of 82 included patients, 81 were analyzed on an intention-to-treat basis (intervention group: n = 42; control group: n = 39). On inclusion, the intervention and control groups did not differ significantly in terms of demographic and surgical data. The postoperative kinetics of cTnI did not differ significantly between groups: the mean difference was 0.44 ± 1.09 μg/ml, P = .69. Incidence of composite endpoint and GDF-15 values were higher in the sevoflurane group than in propofol group. The intervention and control groups did not differ significantly in terms of ICU stay and hospital stay.Conclusion:The use of an anaesthesia and ICU sedation with sevoflurane was not associated with a lower incidence of myocardial injury assessed by cTnI. Sevoflurane administration was associated with higher prevalence of acute renal failure and higher GDF-15 values.     

Associations between salivary cytokines and periodontal and microbiological parameters in orthodontic patients

Orthodontic treatment can lead to microbial-induced gingival inflammation and aseptic periodontal inflammations. The aim of this study was to investigate the relationship between salivary pro-inflammatory cytokines levels with gingival health status and oral microbe loads among patients undergoing orthodontic treatment.The present investigation was a cross-sectional study among a sample of 111 consecutive orthodontic patients (mean age 18.4 ± 4.4 years). Clinical examinations were conducted to assess the gingival health status employing the Modified Gingival Index, Gingival Bleeding Index, and Plaque Index. Salivary microbiological assessments of total aerobic and anaerobic bacteria count, streptococci count, and lactobacilli count were undertaken. Saliva immunological assessments included Interleukin-1Beta (IL-1β) and macrophage migration inhibitory factor (MIF) ELISA assays.The mean ± standard deviation of salivary IL-1β was 83.52 ± 85.62 pg/ml and MIF was 4.12 ± 0.96 ng/ml. Moderate positive correlations were found between salivary IL-1β levels and total aerobic and anaerobic bacteria count, streptococci count, and lactobacilli count (r = 0.380–0.446, P < .001), and weak positive correlations between salivary MIF levels and total salivary aerobic and anaerobic bacteria counts (r = 0.249–0.306, P < .01) were observed. A positive correlation was found between salivary IL-1β levels and Bleeding Index (r = 0.216, P < .05).The level of salivary IL-1β positively correlates with oral bacterial load among orthodontic patients; the relationship between inflammatory cytokines and oral microflora deserved further study.     

Gastrointestinal and non-gastrointestinal complication rates associated with diagnostic esophagogastroduodenoscopy under sedation

Esophagogastroduodenoscopy (EGD) under sedation may result in gastrointestinal (GI) and non-GI complications. However, no previous studies have reported 30-day GI and non-GI complications after diagnostic EGD under sedation.We conducted a retrospective, observational study of 30-day GI and non-GI complication rates after outpatient diagnostic EGD under sedation in subjects ≥18 years between January 2012 and December 2017 based on a common data model database. Thirty-day complication rates were compared with EGD under sedation or not, type of sedation drugs (midazolam only vs midazolam/propofol) and age groups (18-64 year vs ≥65 year) for GI (bleeding and perforation) and non-GI complications (pneumonia, acute myocardial infarction, congestive heart failure and cerebral stroke).In total, 39,910 were performed with sedation (midazolam only, n = 16,033 and midazolam/propofol, n = 23,864) and 22,894 were performed without sedation. Elderly patients significantly favored EGD without sedation (P < .01). GI and non-GI complication rates were similar between EGD under sedation and without sedation (all P > .1) except for acute myocardial infarction rate, which was significantly higher in EGD without sedation than EGD under sedation (1.7/10,000 vs 0.3/10,000 persons, P = .043). All GI and non-GI complications were also similar between the midazolam/propofol and midazolam only groups as well as between young and old patients (all P > .1).Outpatient diagnostic EGD under sedation has an excellent safety profile. In addition, it can be safely performed with midazolam only or midazolam/propofol and in young and old patients.     

Dissociative symptoms with intravenous ketamine in treatment-resistant depression exploratory observational study

There is evidence for ketamine use in treatment-resistant depression (TRD). Several safety and tolerability concerns arise regarding adverse drug reactions and specific subpopulations. This paper aims to investigate the relationship between dissociative and psychometric measures in course of intravenous ketamine treatment in TRD inpatients with major depressive disorder and bipolar disorder.This study result represents safety data in a population of 49 inpatients with major depressive disorder and bipolar disorder subjects receiving eight 0.5 mg/kg of ketamine intravenous infusions, with a duration of 40 min each, as an add-on treatment to standard-of-care pharmacotherapy, registered in the naturalistic observational protocol of the tertiary reference unit for mood disorders ({"type":"clinical-trial","attrs":{"text":"NCT04226963","term_id":"NCT04226963"}}NCT04226963). The safety psychometrics assessed dissociation and psychomimetic symptomatology with the Clinician-Administered Dissociative States Scale (CADSS) the Brief Psychiatric Rating Scale (BPRS).The significant differences in CADSS scores between measurements in course of the treatment were observed (P = .003). No significant differences between BPRS measurements were made after infusions. In each case, both BPRS and CADSS values dropped to the “absent” level within 1 hour from the infusion. Neither CADSS nor BPRS scores were associated with the treatment outcome.The study demonstrates a good safety profile of intravenous ketamine as an add-on intervention to current psychotropic medication in TRD. The abatement of dissociation was observed in time with no sequelae nor harm. The study provides no support for the association between dissociation and treatment outcome.This study may be underpowered due to the small sample size. The protocol was defined as a study on acute depressive symptomatology without blinding.
