Background: Many studies have reported the use of preoperative oral carbohydrates (CHO) in children, but the results are inconsistent. The aim of this meta-analysis is to assess the effectiveness and safety of oral CHO administration in children prior to surgery, with the goal of offering a dependable reference for clinical nursing practices and surgical interventions. Methods: Two authors searched PubMed, Clinical trials, Web of Science, Embase, Cochrane Library, China national knowledge infrastructure (CNKI), Wanfang and Weipu databases for randomized controlled trial (RCT) on the effects of preoperative oral CHO in children up to April 12, 2024. We used RevMan 5.4 software for data analysis. Results: Nine RCTs involving a total of 1279 children were included. The meta-analysis showed that there was statistical difference in the pH of gastric juice (MD = 1.54, 95%CI: 1.40–1.67, p <.001), intraoperative sedation score (MD = 0.62, 95%CI: 0.27–0.97, p <.001), and the incidence of postoperative nausea and vomiting (OR = 0.40, 95%CI: 0.20–0.80, p =.009) between the CHO and control groups. There was no statistical difference in the RGV (MD = −0.23, 95%CI: −0.47–0.01, p =.06) and the postoperative blood glucose level (MD = −0.91, 95%CI: −5.03–3.21, p =.67) between the CHO and control groups. Egger regression analysis showed that there were no publication biases amongst the synthesized outcomes (all p >.05). Conclusion: The administration of oral CHO to children before surgery is safe and practicable. There is a need for additional, well-conducted studies with more participants to further elucidate the role of preoperative CHO administration. [ABSTRACT FROM AUTHOR]

Introduction: Frailty has become a worldwide health burden that has a large influence on public health and clinical practice. The incidence of frailty is anticipated to increase as the ageing population increases. Myocardial injury after noncardiac surgery (MINS) is associated with short-term and long-term mortality. However, the incidence of MINS in frail geriatric patients is unknown. Methods and analysis: This prospective, multicentre, real-world observational cohort study will be conducted at 18 designated centres in China from January 2023 to December 2024, with an anticipated sample size of 856 patients aged 65 years and older who are scheduled to undergo noncardiac surgery. The primary outcome will be the incidence of MINS. MINS is defined as a fourth-generation plasma cardiac troponin T (cTnT) concentration ≥ 0.03 ng/mL exhibited at least once within 30 days after surgery, with or without symptoms of myocardial ischaemia. All data will be collected via electronic data acquisition. Discussion: This study will explore the incidence of MINS in frail patients. The characteristics, predictive factors and 30-day outcomes of MINS in frail patients will be further investigated to lay the foundation for identifying clinical interventions.

Purpose: To determine the effect of auricular acupuncture on preoperative blood pressure (BP) elevation in different age groups. Materials and methods: Auricular acupuncture treats elevated BP among patients before surgery. This prospective, randomized clinical trial was performed at Li Huili Hospital of Ningbo Medical Center, China, from January to June 2021. We prospectively enrolled 120 patients with elevated BP aged 45 to 75 and observed them in the inpatient department. Patients were randomly assigned in a 1:1 ratio to undergo auricular acupuncture or sham control groups. In addition to usual care, the study group underwent auricular acupuncture bilaterally at HX6 7i-Ear apex, TF4-Shen men, TF1-Superior triangular fossa, and CO15-Heart. Results: A total of 120 patients completed the study, 60 in the study group and 60 in the control group. Of these, 76 (63.3%) were men, and the mean (standard deviation) was 64.55 (9.48) years. The differences in systolic BP comparisons after intervention were significant (7.88 mmHg; 95% confidence interval [CI], 2.94 to 12.81; P = .002). Diastolic BP also showed statistical significance (5.85 mmHg; 95% CI, 3.05 to 8.64; P < .01. Neither AA-related adverse events nor serious adverse events occurred. Stratified by age, the differences comparisons of systolic BP (-10.13 mmHg; 95% confidence interval [CI], -16.69 to -3.57; P < .01) and diastolic BP (-7.65 mmHg; 95% confidence interval [CI], -11.17 to -4.14; P < .01) were statistically significant for participants aged 60-75 years; The differences comparison of systolic BP (-2.37 mmHg; 95% confidence interval [CI], -8.04 to 3.31; P = .40) and diastolic BP (-1.46 mmHg; 95% confidence interval [CI], -5.68 to 2.76; P = .48) were not significant aged 45-59. Conclusion: Auricular acupuncture can reduce BP before procedures. However, further research is needed on the antihypertensive effect on people aged 45-59. These findings provide clinicians with evidence of auricular acupuncture as a standard adjunctive therapy targeting this patient population. [ABSTRACT FROM AUTHOR]

Introduction: After the publication of the 2015 American Thyroid Association (ATA) guidelines, the indication for total thyroidectomy (TT) was reported to be underestimated before surgery, which may lead to a substantial rate of secondary completion thyroidectomy (CTx). Methods and Materials: We retrospectively analyzed differentiated thyroid cancer patients from Wuhan Union Hospital (WHUH). Univariate analysis was performed to evaluate all preoperative and intraoperative factors. New models were picked out by comminating and arranging all significant factors and were compared with ATA and National Comprehensive Cancer Network (NCCN) guidelines in the multicenter prospective Differentiated Thyroid Cancer in China (DTCC) cohort. Results: A total of 5,331 patients from WHUH were included. Pre- and intraoperative criteria individually identified 906 (17.0%) and 213 (4.0%) patients eligible for TT. Among all factors, age <35 years old, clinical N1, and ultrasound reported local invasion had high positive predictive value to predict patients who should undergo TT. Accordingly, we established two new models that minorly revised ATA guidelines but performed much better. Model 1 replaced "nodule size >4 cm" with "age <35 years old" and achieved significant increase in the sensitivity (WHUH, 0.711 vs. 0.484; DTCC, 0.675 vs. 0.351). Model 2 simultaneously demands the presence of "nodule size >4 cm" and "age <35 years old," which had a significant increase in the specificity (WHUH, 0.905 vs. 0.818; DTCC, 0.729 vs. 0.643). Conclusion: All high-risk factors had limited predictive ability. Our model added young age as a new criterion for total thyroidectomy to get a higher diagnostic value than the guidelines.

Objective: To explore the value of multi-slice spiral CT (MSCT) in predicting microvascular invasion in hepatocellular carcinoma (HCC). Methods: The CT and clinical data of 102 patients with HCC were collected for retrospective analysis from January 2018 to December 2020 at Baoji Center Hospital, China. They were divided into two groups based on the pathological results with or without microvascular invasion. The independent sample t-test was used to compare the age, alpha-fetoprotein (AFP) value, tumor size, and tumor enhancement of the two groups. CT value; χ2 test was used to compare gender, hepatitis type, liver function classification, degree of classification, degree of tumor smoothness, envelope, peripheral enhancement, etc. between the two groups. Results: There were 52 cases of non-microvascular invasion and 50 cases of microvascular invasion. The tumor size, grade, degree of margin, capsule, portal vein CT value, and peripheral enhancement were related to microvascular invasion. Conclusion: Microvascular invasion of HCC can be predicted by MSCT manifestations before surgery. [ABSTRACT FROM AUTHOR]

Introduction: A trade-off between successful surgery and minimizing the operation delay for patients with spinal tuberculosis (TB) is a major consideration to determine the duration of preoperational anti-TB treatment (AAT). In this study, 2 and 4 weeks preoperative AAT durations were compared for their influence on the operation outcomes. Method: A multicenter, prospective, randomized trial was conducted in four hospitals in China. New patients with spinal TB were recruited and randomly allocated to two groups (2 or 4 weeks' preoperative treatment) and administered the standardized first-line anti-TB drugs. The symptom changing and indicators reflecting recovery and side effects of the treatment were monitored. Patient was followed up for another 18 months after completion of treatment. Results: In total, 150 eligible patients were enrolled between June 2014 and December 2016, and 13 patients were excluded after the enrollment. The remaining 137 participants were randomly allocated to the 2-week group (n = 68) or the 4-week group (n = 69). These two groups acquired similar surgical outcomes, considering wound healing rate within 3 months after the operation (94.20%, 65/69 vs 89.71%, 61/68; P = 0.333) and bony fusion rate within 6 months (98.46%, 64/65 vs 95.45%, 63/66; P = 0.317). However, the culture positive rate of pus collected during operation in the 4-week group (41.94%) was significantly lower than that of the 2-week group (60.94%, P = 0.033). No reoccurrence of disease was observed in either group during the 18-month follow-up period. Conclusion: Patients with spinal TB administered 2 or 4 weeks of preoperative anti-TB treatment acquired similar surgical outcomes. However, patients who underwent the operation sooner suffered 2 weeks less agony from the disease. [ABSTRACT FROM AUTHOR]

Background: Currently, botulinum toxin A (BTA) is mainly used in the treatment of muscle spasms and in cosmetic procedures, and its cosmetic indications are expanding rapidly. There have been sporadic reports focused on the preoperative usage of BTA complementing plastic surgery. We briefly summarize the current experience of BTA complementing plastic surgery in China based on clinical experience. Methods: We reported a brief review of the preoperative use of BTA as an accessory to plastic surgery (blepharoplasty, chin augmentation, mandibular angle ostectomy, rhinoplasty, hyaluronic acid fillers injection for wrinkle reduction) based on previous studies and our experience. Results: Preoperative treatment with BTA in plastic surgery helps surgeons operate and results in better cosmetic results. Conclusions: Preoperative BTA treatment can reduce the occurrence of surgical complications as well as improve the surgical results in some plastic surgeries. The procedure is suitable for clinical application and worth promoting. [ABSTRACT FROM AUTHOR]

Localization of a ground glass nodule is a difficult challenge for thoracic surgeons, especially for ground glass opacities ( GGOs) less than 10 mm in diameter. In this study we implement a new method for preoperative localization of pulmonary ( GGOs). From October 2013 to December 2014, computed tomography-guided percutaneous polylactic acid injection localizations were performed for five pulmonary nodules in five patients (2 men and 3 women; mean age, 59.8 years; range, 54-65 years). The injection was feasible in all patients and the localization effect was excellent. The total procedure duration was 12.6 minutes (range; 10-15) and the volume of polylactic acid injected was 0.38 mL. The wedge resections were easily and successfully performed in all five cases. The cutting margin was no less than 2 cm from the lesion. This technique is promising for the determination of GGO location in thoracoscopic surgery for wedge resection. [ABSTRACT FROM AUTHOR]

Background: Delayed cerebral ischemia is a serious complication of aneurysmal subarachnoid hemorrhage with debilitating and fatal consequences. Lack of well-established risk factors impedes early identification of high-risk patients with delayed cerebral ischemia. A nomogram provides personalized, evidence-based, and accurate risk estimation. To offset the lack of a predictive tool, we developed a nomogram to predict delayed cerebral ischemia before performing surgical interventions for aneurysmal subarachnoid hemorrhage to aid surgical decision-making., Methods: We retrospectively collected data from 887 consecutive eligible Chinese patients who underwent surgical clipping or endovascular coiling for aneurysmal subarachnoid hemorrhage. Patients who previously underwent surgery formed the training cohort (n = 621) for nomogram development; those who underwent surgery later formed the validation cohort (n = 266) to confirm the performance of the model. A multivariate logistic regression analysis identified the independent risk factors associated with delayed cerebral ischemia, which were then incorporated into the nomogram., Results: Delayed cerebral ischemia was identified in 158/621 patients (25.4%) in the training cohort and in 66/266 patients (24.8%) in the validation cohort. Preoperative factors associated with delayed cerebral ischemia were age > 65 years, modified Fisher grade of 3-4, ruptured aneurysm in the anterior circulation, Hunt-Hess grade of 4-5, high blood pressure on admission, and plasma homocysteine level ≥ 10 μmol/L. Incorporating these six factors in the nomogram achieved efficient concordance indices of 0.73 (95% confidence interval, 0.68-0.77) and 0.65 (95% confidence interval, 0.57-0.72) in predicting delayed cerebral ischemia in the training and validation cohorts, respectively., Conclusions: Our model can help determine an individual's risk of developing delayed cerebral ischemia in the Chinese population, and thereby, facilitate reasonable treatment-related decision-making., Competing Interests: Declaration of Competing Interest None., (Copyright © 2020.

Background: Because of the powerful abilities of self-learning and handling complex biological information, artificial neural network (ANN) models have been widely applied to disease diagnosis, imaging analysis, and prognosis prediction. However, there has been no trained preoperative ANN (preope-ANN) model to preoperatively predict the prognosis of patients with gastric cancer (GC)., Aim: To establish a neural network model that can predict long-term survival of GC patients before surgery to evaluate the tumor condition before the operation., Methods: The clinicopathological data of 1608 GC patients treated from January 2011 to April 2015 at the Department of Gastric Surgery, Fujian Medical University Union Hospital were analyzed retrospectively. The patients were randomly divided into a training set (70%) for establishing a preope-ANN model and a testing set (30%). The prognostic evaluation ability of the preope-ANN model was compared with that of the American Joint Commission on Cancer (8 th edition) clinical TNM (cTNM) and pathological TNM (pTNM) staging through the receiver operating characteristic curve, Akaike information criterion index, Harrell's C index, and likelihood ratio chi-square., Results: We used the variables that were statistically significant factors for the 3-year overall survival as input-layer variables to develop a preope-ANN in the training set. The survival curves within each score of the preope-ANN had good discrimination ( P < 0.05). Comparing the preope-ANN model, cTNM, and pTNM in both the training and testing sets, the preope-ANN model was superior to cTNM in predictive discrimination (C index), predictive homogeneity (likelihood ratio chi-square), and prediction accuracy (area under the curve). The prediction efficiency of the preope-ANN model is similar to that of pTNM., Conclusion: The preope-ANN model can accurately predict the long-term survival of GC patients, and its predictive efficiency is not inferior to that of pTNM stage., Competing Interests: Conflict-of-interest statement: All authors declare that they have no conflicts of interest., (©The Author(s) 2019.
