Epidemiology of burn-related fatalities in Australia and New Zealand, 2009–2015

BackgroundKnowledge of the epidemiology of burn-related fatalities is limited, with most previous studies based on hospital and burn centre data only.AimsTo describe the epidemiological characteristics of all burn-related fatalities in Australia and New Zealand, and to identify any trends in burn-related fatality incidence over the study period.MethodsData from the National Coronial Information System, including data for pre-hospital and in-hospital burn-related fatality cases, was used to examine the characteristics of burn-related fatalities occurring in Australia and New Zealand from 2009 to 2015. Burn-related fatality rates per 100,000 population were estimated, and incidence trends assessed using Poisson regression analysis.ResultsOf the 310 burn-related fatalities that occurred in Australia and New Zealand, 2009–2015, 41% occurred in a pre-hospital setting. Overall, most burn-related fatality cases were fire related, occurred at home, and were of people aged 41–80 years. One quarter of all burn-related fatalities were a result of intentional self-harm. The population incidence of all burn-related fatalities combined, and for NSW, decreased over the study period.ConclusionsThis study has identified the importance of examining all burn-related fatalities. If this is not done, vulnerable population subgroups will be missed and prevention efforts poorly targeted.     

Enhanced surveillance of tetanus toxoid,reduced diphtheria toxoid,and acellular pertussis (Tdap) vaccines in pregnancy in the Vaccine Adverse Event Reporting System (VAERS), 2011–2015

BackgroundIn October 2011, the Advisory Committee on Immunization Practices (ACIP) issued updated recommendations that all pregnant women routinely receive a dose of tetanus toxoid, reduced diphtheria toxoid, and acellular pertussis (Tdap) vaccine.ObjectivesWe characterized reports to the Vaccine Adverse Event Reporting System (VAERS) in pregnant women who received Tdap after this updated recommendation (2011–2015) and compared the pattern of adverse events (AEs) with the period before the updated recommendation (2005–2010).MethodsWe searched the VAERS database for reports of AEs in pregnant women who received Tdap vaccine after the routine recommendation (11/01/2011–6/30/2015) and compared it to published data before the routine Tdap recommendation (01/01/2005–06/30/2010). We conducted clinical review of reports and available medical records. The clinical pattern of reports in the post-recommendation period was compared with the pattern before the routine Tdap recommendation.ResultsWe found 392 reports of Tdap vaccination after the routine recommendation. One neonatal death but no maternal deaths were reported. No maternal or neonatal deaths were reported before the recommendation. We observed an increase in proportion of reports for stillbirths (1.5–2.8%) and injection site reactions/arm pain (4.5–11.9%) after the recommendation compared to the period before the routine recommendation for Tdap during pregnancy. We noted a decrease in reports of spontaneous abortion (16.7–1%). After the 2011 Tdap recommendation, in most reports, vaccination (79%) occurred during the third trimester compared to 4% before the 2011 Tdap recommendation. Twenty-six reports of repeat Tdap were received in VAERS; 13 did not report an AE. One medical facility accounted for 27% of all submitted reports.ConclusionsNo new or unexpected vaccine AEs were noted among pregnant women who received Tdap after routine recommendations for maternal Tdap vaccination. Changes in reporting patterns would be expected, given the broader use of Tdap in pregnant women in the third trimester.     

放疗在肝癌治疗中应用的研究进展

肝癌是临床上常见的恶性肿瘤，因早期症状不典型，至发现时往往已为中晚期，失去最佳手术治疗时机和机会。作为非手术治疗之一的放射治疗技术，其发展在近年来已有了较大的进步。放疗包括体外放疗和体内放疗，皆具有一定的治疗效果和相对可控的不良反应。本文就肝癌放射治疗的应用进展作一综述。     

缺血性脑血管病患者脑微出血相关因素及其对抗血小板单药治疗的影响分析

目的 研究缺血性脑血管病患者脑微出血（CMB）危险因素及其对抗血小板单药治疗的影响。方法 选取2018年1月至2018年6月该院神经内科接受抗血小板单药治疗的急性缺血性脑血管病患者300例为样本，入院后采集基本资料并完善相关检查，根据梯度回波T2^*加权成像（GRE-T2^*WI）检查结果将患者分为CMB组（176例）和非CMB组（124例），均给予抗血小板聚集治疗，比较两组临床资料及治疗1年内再发梗死、脑出血和病死率，分析影响CMB发病的危险因素以及CMB对抗血小板单药治疗的影响。结果 高龄、高血压、肥胖、脑卒中病史、ACI和脑白质疏松为CMB发生的危险因素（P<0.05）。CMB组和非CMB组抗血小板单药治疗期间脑出血率分别为14.20%和6.45%，差异有统计学意义（P<0.05）。轻度组、中度组和重度组脑出血率分别为9.18%、10.64%和35.48%，差异有统计学意义（P<0.05）。不同部位CMB患者抗血小板单药治疗期间再发脑梗死、脑出血及病死率比较，差异无统计学意义（P>0.05）。结论 高龄、高血压、肥胖、脑卒中病史、ACI及脑白质疏松为缺血性脑血管疾病合并CMB的危险因素。CMB可导致抗血小板单药治疗期间脑出血风险增加，重度CMB者更甚。     

Resurgence of pertussis in Taiwan during 2009–2015 and its impact on infants

Background/purposePertussis incidence markedly decreased due to universal vaccination, but outbreaks had been noted worldwide in recent decade. This study was conducted to know the epidemiology of pertussis and its impact on infants in Taiwan.MethodsEpidemiologic parameters for confirmed pertussis cases were collected from the Taiwan Centers for Disease Control. The incidence of each age group over years was calculated using population data. We also did retrospective reviews of laboratory-confirmed pertussis cases in NTUH to analyze clinical characteristics and disease severity.ResultsA total of 668 confirmed pertussis cases were obtained from the Taiwan CDC open database between 2003 and 2017. There was higher incidence during the period 2009–2015, with a mean incidence of 0.27 cases per 100,000 population, about 2-fold increase compared with mean incidence of 0.12 cases per 100,000 population during the period 2003–2008. Infants accounted for the highest proportion of all cases (49.8%), with mean incidence of 16.1 cases per 100,000 people per year during 2009–2015, and a trend of increase was found from 2003 to 2015. In NTUH, a total of 17 laboratory-confirmed pertussis cases were diagnosed during 2012–2016, and 14 cases were young infants. Among them, 9 infants had been admitted to intensive care unit and 2 infant needed invasive ventilator support.ConclusionThere was a resurgence of pertussis during 2009–2015 and it had significant impact on infants. Young infants with pertussis may be severe and need intensive care, so preventive strategy may be advocated for them.

Introduction

Little is known about dementia incidence in diverse populations of oldest-old, the age group with highest dementia incidence.

Patient-Centered Framework for Rehabilitation Research in Outpatient Settings

Conducting high-quality clinical research is dependent on merging scientific rigor with the clinical environment. This is often a complex endeavor that may include numerous barriers and competing interests. Overcoming these challenges and successfully integrating clinical research programs into clinical practice settings serving rehabilitation outpatients is beneficial from both a logistical perspective (eg, supports efficient and successful research procedures) and the establishment of a truly patient-centered research approach. Leveraging our experience with navigating this research-clinical care relationship, this article (1) proposes the Patient-Centered Framework for Rehabilitation Research, a model for integrating patient-centered research in an outpatient clinical setting that incorporates a collaborative, team-based model encompassing patient-centered values, as well as strategies for recruitment and retention, with a focus on populations living with disabilities or chronic diseases; (2) describes application of this framework in a comprehensive specialty multiple sclerosis center with both general strategies and specific examples to guide adaptation and implementation in other settings; and (3) discusses the effect of the framework as a model in 1 center, as well as the need for additional investigation and adaptation for other populations. The 5 interconnected principles incorporated in the Framework and which prioritize patient-centeredness include identifying shared values, partnering with the clinical setting, engaging with the population, building relationships with individuals, and designing accessible procedures. The Patient-Centered Framework for Rehabilitation Research is a model presented as an adaptable roadmap to guide researchers in hopes of not only improving individual patients’ experiences but also the quality and relevance of rehabilitation research as a whole. Future investigation is needed to test the Framework in other settings.
