甲磺酸伊马替尼联合VDLD化疗方案治疗急性淋巴细胞白血病患儿的长期随访研究

目的探究甲磺酸伊马替尼联合VDLD化疗方案治疗急性淋巴细胞白血病(ALL)患儿的应用价值。方法选取2015年5月~2018年6月收治的74例ALL患儿,按照治疗方案不同分组。对照组(37例)实施VDLD方案治疗,联合组(37例)实施甲磺酸伊马替尼+VDLD化疗方案治疗。对比两组疗效、不良反应发生率、随访1年无复发生存率(RFS)及治疗前、治疗2个疗程后血清B淋巴细胞刺激因子(BAFF)、增殖诱导配体(APRIL)水平。结果联合组总有效率(91.89%)高于对照组(72.97%)(P<0.05);联合组治疗2个疗程后血清BAFF、APRIL水平低于对照组(P<0.05);两组不良反应发生率、随访1年RFS对比无显著差异(P>0.05)。结论甲磺酸伊马替尼联合VDLD化疗方案治疗ALL,疗效确切,能显著降低血清BAFF、APRIL水平,且安全性高。     

支气管哮喘急性发作期气道炎症表型与中医辨证分型的关系

支气管哮喘是由多种细胞和细胞组分参与的气道慢性炎症性疾病,其气道炎症反应的复杂性,给临床诊断和治疗带来了困难[1]。2009年全球哮喘防治倡议(GINA)第一次提出“表型”这一概念,并提出基于表型分类有助于哮喘治疗及判断预后[2]。中医药治疗哮喘有其独特优势,但辨证分型缺乏明确统一的客观化、量化指标。     

护士分层级管理对急性肝炎患者护理满意度的影响

目的分析护士分层级管理的实施对急性肝炎患者护理满意度的影响。方法该院自2018年3月起实施护士分层级管理,以该院10名肝病科护理人员为研究对象,其中2017年3月—2018年2月实施前(对照组)及2018年3月—2019年2月实施后(研究组)的管理效果。结果与对照组比较,研究组患者的病房管理、患者护理、文书书写、基础护理、入院宣教方面的护理质量评分均明显升高(P<0.05);与对照组82.29%的护理总满意率比较,研究组护理总满意率显著升高,达到了97.92%(P<0.05);与对照组工作自我满意度比较,研究组患者的自我价值体现等方面的工作自我满意度评分均明显升高(P<0.05)。结论护士分层级管理策略的实施,有效提高了急性肝炎患者护理满意度,提升了科室护理质量。     

经鼻导管高流量吸氧与经鼻气道正压通气在重症毛细支气管炎呼吸支持中的应用价值比较

目的：比较经鼻导管高流量吸氧（HFNC）与经鼻气道正压通气（nCPAP）在重症毛细支气管炎呼吸支持中的应用价值，为临床治疗方案的选择提供参考。方法：选取2016年12月至2018年12月我院儿科收治的重症毛细支气管炎患儿90例，采用随机数字表法分为观察组和对照组各45例。两组患儿入院后均给予常规综合治疗以保证呼吸道通畅，在此基础上观察组采用HFNC治疗，对照组采用nCPAP治疗，比较两组患儿治疗前和治疗24 h后呼吸频率、经皮血氧饱和度（TcSO2）、呼吸窘迫评分体系（CSS）评分、动脉血氧分压（PaO2）等呼吸相关指标及治疗前后临床症状体征改善情况。结果：两组患儿治疗24 h后呼吸频率、CSS评分均降低，且观察组降低程度更大，TcSO2、PaO2于治疗24 h后升高，观察组升高幅度较对照组明显；治疗后两组患儿咳嗽及肺部湿啰音、肺部炎症情况均改善，观察组症状体征消失时间早于对照组，差异均有统计学意义（P<0.05）。结论：重症毛细支气管炎患儿采用HFNC治疗可明显改善通气功能和临床症状，治疗效果优于nCPAP治疗，可扩大样本量进一步观察。     

Pharmacotherapeutic strategies for critical asthma syndrome: a look at the state of the art

ABSTRACT

Introduction

‘Critical Asthma Syndrome’ (CAS) is an umbrella term proposed to include several forms of asthma, responsible for acute and life-threatening exacerbations. CAS requires urgent and adequate supportive and pharmacological treatments to prevent serious outcomes.     

Utilization and Complications of Central Venous Access Devices in Oncology Patients

Purpose: To describe how central venous access devices (CVADs) are utilized for ambulatory oncology patients and to evaluate the rate of complications. Method: Single institution retrospective study of oncology patients with CVADs who received systemic treatment at the Walker Family Cancer Centre (WFCC) between 1 January and 31 December 2018. Results: A total of 480 CVADS were placed in 305 patients, of which 408 (85%) were peripherally inserted central catheters (PICCs) and 72 (15%) were implanted vascular access devices (PORTs). The incidence of early and late complications was 9% and 24%, respectively. For the entire cohort, the rate of venous thromboembolism (VTE) was 16%, of which 9% were CVAD-related thrombosis (CRTs) and 7% were distant VTE. The CRT rates were similar for PICCs and PORTs (9% vs. 7%). A total of 6% of CVADs were complicated by infection (i.e., localized infections and bacteremia), with a total infection rate of 0.43 and 0.26 per 1000 indwelling days for PICCs and PORTs, respectively. The incidence of central line associated bloodstream infections (CLABSI) was greater for PICCs than PORTs, at a rate of 0.22 compared with 0.08 per 1000 indwelling days, respectively. The premature catheter removal rate was 26% for PICCs and 18% for PORTs. PORTs required more additional hospital visits. Conclusions: PICCs were utilized more frequently than PORTs and had a higher rate of premature removal. The rates of VTE and CRT were similar for both CVAD types. PORTs had a lower rate of infection per 1000 indwelling days. However, the management of PORT related complications required more visits to the hospital and oncology clinic.     

Effectiveness of the 10-valent pneumococcal conjugate vaccine against radiographic pneumonia among children in rural Bangladesh: A case-control study

BackgroundPneumococcal conjugate vaccine (PCV) effectiveness against radiographic pneumonia in South Asia is unknown. Bangladesh introduced PCV10 in 2015 using a three dose primary series (3 + 0). We sought to measure PCV10 effectiveness for two or more vaccine doses on radiographic pneumonia among vaccine-eligible children in rural Bangladesh.MethodsWe conducted a matched case-control study over two years from 2015 to 2017 using clinic and community controls in three subdistricts of Sylhet, Bangladesh. Cases were vaccine eligible 3–35 month olds at Upazila Health Complex outpatient clinics with World Health Organization-defined radiographic primary endpoint pneumonia (radiographic pneumonia). Clinic controls were matched to cases within a one week time window by age, sex, and clinic and had an illness unlikely to be Streptococcus pneumoniae; community controls were healthy and similarly matched within a one week time window by age and sex, and distance from the clinic. We estimated adjusted vaccine effectiveness (aVE) using conditional logistic regression.ResultsWe matched 1262 cases with 2707 clinic and 2461 community controls. Overall, aVE using clinic controls was 21.4% (95% confidence interval, −0.2%, 38.4%) for ≥2 PCV10 doses and among 3–11 month olds was 47.3% (10.5%, 69.0%) for three doses. aVE increased with higher numbers of doses in clinic control sets (p = 0.007). In contrast, aVE using community controls was 7.6% (95% confidence interval, −22.2%, 30.0%) for ≥2 doses. We found vaccine introduction in the study area faster and less variable than expected with 75% coverage on average, which reduced power. Information bias may also have affected community controls.ConclusionsClinic control analyses show PCV10 prevented radiographic pneumonia in Bangladesh, especially among younger children receiving three doses. While both analyses were underpowered, community control enrollment – compared to clinic controls – was more difficult in a complex, pluralistic healthcare system. Future studies in comparable settings may consider alternative study designs.     

竹叶石膏汤合清气化痰丸加减治疗急性加重期慢性阻塞性肺疾病分析

目的:分析竹叶石膏汤合清气化痰丸加减治疗急性加重期慢性阻塞性肺疾病(Acute Exacerbations of Chronic Obstructive Pulmonary Disease,AECOPD)疗效。方法:以2017年1月-2019年1月收治的AECOPD患者80例,随机分为两组,各40例。对照组采用常规西药治疗,观察组在对照组基础上采用竹叶石膏汤合清气化痰丸加减治疗。比较两组治疗前后肺功能指标[第1秒用力呼气容积占预计值百分比(Forced Expiratory Volume,FEV1%)、第一秒用力呼气肺容积(Forced Expiratory Volume,FEV1)]、改良版英国医学研究委员会呼吸问卷(mMRC)、慢阻肺患者自我评估测试问卷(CAT)等评分变化以及疗效。结果:在FEV1%、FEV1等肺功能指标上,两组治疗前对比无统计学差异(P>0.05);而观察组治疗后均高于对照组,二者差异存在统计学意义(P<0.05)。在mMRC、CAT等评分上,两组治疗前差异对比无统计学意义(P>0.05);而观察组治疗后均低于对照组,二者差异存在统计学意义(P<0.05)。在治疗有效率上,对照组总体为82.5%(33/40),观察组总体为95.0%(38/40),二者差异对比存在统计学意义(P<0.05)。结论:竹叶石膏汤合清气化痰丸加减治疗AECOPD的疗效确切,即可有效改善患者肺功能和临床症状,且利于其预后康复,因此值得应用推广。     

Infecciones de transmisión sexual en hombres internos en prisión: riesgo de desarrollo de nuevas infecciones

ObjectiveTo measure incidence and main risk factors related to sexually transmitted infections (STIs) in Daroca Prison (Zaragoza, Spain).MethodA retrospective cohort study (2005-2013) to measure the incidence of STI and a cross-sectional study to measure risk factors.ResultsOf the 203 inmates, 79 developed an STI, 37 had a previous STI, 55.2% lacked knowledge on STI prevention, and 28.9% showed behaviours unfavourable for STI prevention. The incidence rate was 6.5 STIs per 1,000 inmates-year. The most frequent STIs were hepatitis B (39.7%), Ureaplasma urealyticum (19.1%), herpes simplex (16.2%) and HIV (8.8%). The risk (hazard ratio, HR) of acquiring a new STI was significantly higher in inmates with a history of previous STI (HR = 2.61; 95%CI: 1.01 to 6.69), and was at the limit of significance for non-preventive behaviour (HR = 2.10; 95%CI: 0.98 to 4.53), but not in knowledge related to STIs (HR = 1.33; 95%CI: 0.58 to 3.07).ConclusionThe most important risk factors in prison are behaviours related to STIs and previous history of STIs. Other factors are being a repeat offender, injecting drug use, or being in a methadone programme. Health personnel and peer education can facilitate prevention and control.
