Performance of EAST in diagnosing inhalant allergens in children with allergic rhinitis

The performance of enzyme linked immunosorbent assays (EAST) for identifying six indoor allergens was evaluated using skin prick test (SPT) as reference tests in 154 children with allergic rhinitis. Sensitivity of EAST ranged from 9% (cat) to 54% (HDM) with specificity of 74%(cockroach) to 100% (cat) with an agreement ranged from 58 to 86%. Cut off values ?> ?0.35 kU/L showed best sensitivity and specificity. Our findings agree with extant literature which suggests that the ability of EAST to determine the precipitating allergen is moderate. Assays for definitively identifying the inhalant allergen are currently not available.

Successful treatment of linezolid-induced severe lactic acidosis with continuous venovenous hemodiafiltration: A case report

Linezolid is an oxazolidinone antibiotic. Linezolid-associated lactic acidosis has been reported in 6.8% of linezolid-treated patients. Lactic acidosis is associated with poor clinical outcomes, with high blood lactate levels resulting in organ dysfunction and mortality. This case report describes the development of lactic acidosis in a 64-year-old Chinese woman who had received 33 days of treatment with antituberculosis drugs and 28 days of treatment with oral linezolid for tuberculous meningitis. Severe lactic acidosis was reversed by withdrawing antituberculosis drugs and using continuous venovenous hemodiafiltration (CVVH). When the patient's condition was stable, she was transferred to the infectious disease department, and antituberculosis drugs, with the exception of linezolid, were reintroduced. This did not result in recurrence of lactic acidosis. The causal relationship between lactic acidosis and linezolid was categorized as ‘probable’ on the Adverse Drug Reaction Probability Scale. This case demonstrates that CVVH has potential as an alternative to discontinuation of linezolid alone for rapid reversal of linezolid-associated severe lactic acidosis.

胃癌患者根治术后腹腔灌洗液中CEA mRNA表达的临床意义

目的：探讨胃癌患者根治术后腹腔冲洗液中CEA mRNA表达情况及其临床意义。方法: 回顾性分析了2013 年1 月至2017 年12 月在南京大学医学院附属鼓楼医院接受胃癌根治切除术后进行腹腔灌洗液CEA mRNA检测的139 名患者的病历资料，并进行术后常规随访。用RT-PCR检测139 胃癌患者根治术后腹腔灌洗液中CEA mRNA表达情况。卡方检验分析腹腔灌洗液中CEA mRNA表达与临床基本特征、组织病理学资料、血液学指标及复发方式之间的关系。采用Logistic 单因素及多因素回归分析筛查影响CEA mRNA表达水平的因素。结果：139 名患者中44 名（31.7%）患者腹腔灌洗液CEA mRNA阳性。分析显示，胃癌患者腹腔灌洗液CEA mRNA阳性表达与性别、年龄、病理分级、Lauren 分型和HER2、EGFR、VEGFR等标记物间均没有明显的关联（均P>0.05），与病理类型、脉管是否侵犯、局部浸润深度、淋巴结转移程度和临床AJCC 分期有明显的关联（均P<0.05）。CEA mRNA阳性患者腹膜复发率明显高于阴性患者（P=0.012）。Logistic 单因素回归分析显示，印戒细胞癌（P=0.04，HR=2.810，95% CI: 1.050~7.520）、T 分期（P=0.016，HR=6.329，95% CI: 1.417~28.264）、N 分期（P=0.022，HR=3.068，95% CI: 1.172~8.027）、AJCC分期（P=0.016 ，HR=3.971 ，95% CI: 1.295~12.173 ）、神经侵犯（P=0.002 ，HR=6.738，95% CI: 1.995~22.757）、脉管侵犯（P<0.001，HR=16.36，95% CI: 3.85~69.512）为胃癌患者腹腔灌洗液CEA mRNA阳性表达的危险因素。Logistic 多因素回归分析显示，经过对其他因素的校正，脉管侵犯（P<0.001，HR=21.314，95% CI: 4.21~107.907）为胃癌患者腹腔灌洗液CEA mRNA阳性表达的独立危险因素。结论：胃癌腹腔灌洗CEA mRNA阳性的患者腹膜复发转移风险高且预后不良，应考虑包括腹腔局部治疗在内的更加积极的抗肿瘤治疗。     

Cardiovascular effects and mechanisms of sodium-glucose cotransporter-2 inhibitors

Sodium-glucose cotransporter-2 inhibitors (SGLT2 inhibitors) are a new type of drug for the treatment of diabetes, and they have been proven to have a good hypoglycemic effect. Several lines of clinical evidence have shown that SGLT2 inhibitors can significantly reduce the risks of atherosclerosis, hospitalization for heart failure, cardiovascular death, and all-cause mortality and delay the progression of chronic kidney disease. Because of the protective effects of SGLT2 inhibitors on the heart and kidney, they are being studied for the treatment of heart failure and chronic kidney disease in patients without diabetes. Therefore, it is necessary for cardiologists, patients with diabetes, and nephrologists to fully understand this type of drug. In this review, we summarize the following three aspects of SGLT2 inhibitors: the recent clinical evidence of their cardiovascular benefits, their mechanisms of action, and their safety.

Conditional survival in patients with spontaneous tumor rupture of hepatocellular carcinoma after partial hepatectomy: a propensity score matching analysis

BackgroundSpontaneous tumor rupture (STR) of hepatocellular carcinoma (HCC) is a life-threatening condition. This study investigates the influences of STR on the observed survival and conditional survival of patients received hepatectomy.MethodsA retrospective cohort of patients who underwent hepatectomy from 2009 to 2013 was divided into tumor rupture group and non-rupture group. Propensity score matching (PSM) was used for comparison of the observed survival and conditional survival probabilities between these two groups.Results89 pairs of patients who had comparable background and tumor characteristics were created using PSM analysis. There was significant association between STR and increased risk of OS no matter when before or after PSM (p < 0.01). STR was significantly associated with increased risks of PFS before, while not after PSM. Multivariate Cox regression analyses demonstrated that STR was an independent risk factor associated with OS. There were significant differences in two groups for conditional probabilities of OS and PFS for an additional 6 months and 1 year before PSM, while not after PSM.ConclusionsThis study identified STR but not PFS as an independent risk factor influencing OS, in patients with HCC following hepatectomy. In selected patients with STRHCC, hepatectomy should be performed with acceptable outcomes.     

南京市儿童医院高校志愿服务现状调查与对策研究

目的:对南京市儿童医院高校志愿服务现状进行调查与分析,为完善志愿服务管理体系和服务模式提供对策建议。方法:设计调查问卷,对江苏省内8所大学院校参与我院志愿服务的高校志愿者进行调查,了解医院志愿服务现状。结果:高校志愿者参与医院志愿服务较多的是门诊导医和活动室活动,个人志愿服务时间的累计和记录、服务对象的感谢、社会大众的尊重和认可是高校志愿者参与志愿服务的主要动力,时间因素和距离因素是阻力因素。缺少相关知识培训、缺少宣传拓展渠道、缺少有效激励机制、服务时间不稳定、患者/家属不理解、缺乏吸引力、缺少法律制度保障是目前医院志愿服务不足之处。结论:需从丰富高校学生志愿服务的形式和内容、建立有效的激励机制、完善高校志愿者培训机制以及健全志愿者管理体系四个方面提升高校学生志愿服务的实效性。
