Review of Chinese Journal of Traumatology in the year 2018

Trauma is one of the leading causes of death worldwide. It is an urgent task to strengthen the trauma care and prevent the complications. In 2018, Chinese Journal of Traumatology reported a series of trauma-related articles of which the contents include pre-hospital care, in-hospital care and complication prevention, et al, aiming to improve the treatment levels, decrease the trauma incidence, and reduce the trauma mortality and disability.     

Association Between Serum C-Reactive Protein Concentration and Nutritional Status of Malignant Tumor Patients

Background: The level of the systemic inflammatory marker C-reactive protein (CRP) is elevated in many patients with malignant disease and may be related to nutritional status.

Objective: To analyze the association between serum CRP levels in patients with malignant tumors and their nutritional status.

Method: A total of 3,692 cases were analyzed and the serum CRP levels were determined using an immunometric assay. Nutritional status was assessed by using patient-generated subjective global assessment (PG-SGA). The biochemical evaluation of prealbumin (PA), albumin (ALB), cholesterol (CHOL), and triglycerides (TG) were assayed within 48?h admission to the hospital. The association between serum CRP concentration and the nutritional status, the stage of the tumor and other factors was analyzed by univariate and multivariate logistic regression analysis.

Result: Elevated serum CRP was observed in 47.6% (1,548/3,269) of patients compared with the reference value, and the median CRP concentration was 18.29?mg/l. Patient serum CRP concentrations in the malnourished group (PG-SGA B?+?C) were higher than in the well-nourished (PG-SGA A) patients (P?<?0.05). The serum CRP level was related to the patients' age, gender, tumor stage, and was affected by hepatitis, liver cirrhosis, diabetes, but it has no effect on hypertension. The CRP high patients had lower PA and ALB levels, lower Karnofsky performance status scores, and higher PG-SGA scores (P?<?0.05), and there was no relationship with CHOL and TG levels. Weight loss in the previous 1?mo was seen with CRP positive patients (P?<?0.05).

Conclusion: Almost 50% of malignant tumor patients had elevated serum CRP levels indicating a systemic inflammatory state. The nutritional status was worse in cancer patients with higher concentrations of serum CRP. The level of CRP was associated with the tumor stage, and, as stage is a prognostic factor, so can CRP be used as a prognostic maker in malignant tumors patients.     

Effect of recent seasonal influenza vaccination on serum antibody responses to candidate pandemic influenza A/H5N1 vaccines: A meta-analysis

Recent studies have suggested that among those receiving seasonal influenza vaccine (SIV), reduced immunogenicity is observed in recently vaccinated (RV; within the past season or 2) persons when compared with those not recently vaccinated (NRV). We performed a meta-analysis to assess the effect of recent immunization with SIV on serum H5 hemagglutination inhibition (HAI) antibody responses after influenza A/H5N1 vaccination using data from a series of randomized controlled trials. The primary outcome was seroconversion measured by HAI assays following receipt of 2 doses of H5N1 vaccine. The geometric mean titer (GMT) of serum HAI antibody after vaccination was the secondary outcome. Analyses were performed using propensity score (PS) matching. The PS for each individual in the meta-analysis cohort was calculated using logistic regression and covariates included age, gender, race, antigen dose, adjuvant, statin use and vaccine manufacturer. 2015 subjects enrolled in 7 clinical trials were eligible for inclusion in the meta-analysis cohort; among these, 915 (45%) were RV. 901 RV subjects were matched (1:1) with replacement to a subject who was NRV. Subjects who received SIV within the previous season were significantly less likely to seroconvert following H5N1 vaccination (adjusted odds ratio 0.76; 95%CI 0.60–0.96; p = 0.024), and the GMT was 18% higher among NRV subjects (GM ratio of HAI antibody 1.18; 95%CI 1.04–1.33; p = 0.008). Further work is needed to better define the effects of, and mechanisms contributing to, reduced immune responses to H5N1 vaccine among RV subjects.

目的探讨低分子肝素钙预防腰椎退行性疾病术后深静脉血栓形成(DVT)的有效性和安全性。方法回顾性分析广安市广安区人民医院68例腰椎退行性疾病患者的临床资料,术后均采用抗凝预防血栓形成,按照术后预防DVT所采用方式的不同分为对照组和低分子肝素钙组。分析比较2组患者术后引流量、切口愈合情况、DVT发生率、皮下瘀斑情况、血小板数值、凝血功能、D-二聚体。结果术后2组患者引流量、切口愈合情况、皮下瘀斑情况、凝血功能相关指标比较,差异无统计学意义(P>0.05)。术前和术后1、10 d 2组患者血小板数量的变化差异无统计学意义(P>0.05)。DVT发生率2组患者比较差异有统计学意义(P<0.05)。术前及术后1 d 2组患者D-二聚体比较,差异无统计学意义(P>0.05);术后10 d,对照组患者D-二聚体显著增加,2组比较差异有统计学意义(P<0.05)。结论腰椎退行性疾病术后使用低分子肝素钙进行抗凝,可以显著降低DVT的发生率,具有良好的安全性。     

关于加强临床营养教育的若干建议

临床营养学作为一门重要的综合学科,已经成为临床治疗中重要的组成部分.临床营养教育是依靠临床营养学这门课程,为培养更加专业的临床营养学人才开展的一门新的教育课程.目前我国的临床营养学教育现状不容乐观,医学院校对临床营养学课程重视不够,在专业教学内容和课程建设方面均无法满足社会需求.通过借鉴国外营养教育制度,并结合国内临床营养人才需求现状,应注意不同专业的医学生在日后工作对临床营养的需求,逐渐开展临床营养学必修课教学,加强营养在临床应用的实践教学;并完善毕业后教育体系,对所有规范化培训的医师增加要求到临床营养科轮转培训且不少于1个月,对非临床医学的营养师要求到临床科室轮转至少2个月.提高进修临床医师继续教育及培训营养支持治疗的认识.临床营养专业的教学改革任重而道远,仍需我们不断完善理论体系,积极践行学科理论和知识,满足我国临床营养的人才需求,使社会认识到临床营养对促进健康、预防和治疗疾病的重要性.

Is laparoscopic bariatric surgery as safe and effective before and after age 60? Results from a propensity-score analysis

BackgroundPatients over 60 years old undergoing bariatric surgery is still increasing.ObjectivesFirst, to assess the impact of age (>60 years) on the 90-day morbidity and mortality of both laparoscopic Roux-en-Y gastric bypass (LRYGB) and sleeve gastrectomy (LSG), and second, to determine the effectiveness of surgical weight loss and resolution of obesity-related comorbidities for patients 60 years of age and older over a 2-year period.SettingBicentric study from University Hospital of Caen and Memorial Hospital of Saint Lô, France.MethodsThis is a retrospective review of a prospectively maintained database of patients with morbid obesity undergoing laparoscopic bariatric surgery from October 2005 to April 2019. Patients 60 years of age and older were defined as cases (elderly group [EG], n = 137), and patients younger than 60 years of age were defined as controls (young group [YG], n = 1544). The primary endpoint of the study was the prevalence of severe postoperative complications within 90 days of surgery determined by a propensity-score-matching (PSM) analysis.ResultsThe PSM population included 133 patients in the EG who were matched 1:2 with 266 patients in the YG. There was no mortality in either group. Although not significant (with an absolute difference of 4.5% between the EG and the YG), the odds of severe postoperative complications were 2.5 times higher in the EG than in the YG (7.5% versus 3.0%, P = .053). At 90 days postoperatively, the prevalences of overall morbidity (31.6% versus 22.9%, P = .044), leakage (5.3% versus 1.1%, P = .026), and reoperation (5.3% versus 1.1%, P = .026) were significantly higher in the EG than in the YG.ConclusionThis propensity-matched study suggests that laparoscopic bariatric surgery is probably an effective treatment in obese elderly patients (EPs) in terms of weight loss and resolution of comorbidities. However, the EP should be warned of the increased risk of severe postoperative complications within 90 days, including leakage and reoperation rates, especially after RYGB.
