Policy Recommendations Regarding Skilled Nursing Facility Management of Coronavirus 19 (COVID-19): Lessons from New York State

To provide policy recommendations for managing Coronavirus 19 (COVID-19) in skilled nursing facilities, a group of certified medical directors from several facilities in New York state with experience managing the disease used e-mail, phone, and video conferencing to develop consensus recommendations. The resulting document provides recommendations on screening, protection of staff, screening of residents, management of Coronavirus 19 positive and presumed positive cases, communication during an outbreak, management of admissions and readmissions, and providing emotional support for staff. These consensus guidelines have been endorsed by the Executive Board of the New York Medical Directors Association and the Board of the Metropolitan Area Geriatrics Society.     

某医疗机构核医学工作场所劳务派遣保洁人员的职业健康管理

近几年，"劳务派遣"成了医疗机构终末消毒、保洁、垃圾回收等工作新的用工形式。由于多数用工单位和用人单位不清楚对劳务派遣人员职业健康管理中各自应承担的责任和义务，以至于劳务派遣工在劳动过程中应享有的劳动保护权益未获得切实保障。本文就某医疗机构核医学工作场所劳务派遣保洁人员的职业健康管理监督案例进行讨论。     

Are Medicare's Nursing Home Compare Ratings Accurate Predictors of 90-Day Complications,Readmission, and Bundle Cost for Patients Undergoing Primary Total Joint Arthroplasty?

Background

Nursing Home Compare (NHC) ratings, created and maintained by Medicare, are used by both hospitals and consumers to aid in the skilled nursing facility (SNF) selection process. To date, no studies have linked NHC ratings to actual episode-based outcomes. The purpose of this study was to evaluate whether NHC ratings are valid predictors of 90-day complications, readmission, and bundle costs for patients discharged to an SNF after primary total joint arthroplasty (TJA).

Perception of the Quality of Communication With Physicians Among Relatives of Dying Residents of Long-term Care Facilities in 6 European Countries: PACE Cross-Sectional Study

ObjectiveTo examine how relatives evaluate the quality of communication with the treating physician of a dying resident in long-term care facilities (LTCFs) and to assess its differences between countries.DesignA cross-sectional retrospective study in a representative sample of LTCFs conducted in 2015. Relatives of residents who died during the previous 3 months were sent a questionnaire.Settings and participants761 relatives of deceased residents in 241 LTCFs in Belgium, England, Finland, Italy, the Netherlands, and Poland.MethodsThe Family Perception of Physician-Family Communication (FPPFC) scale (ratings from 0 to 3, where 3 means the highest quality) was used to retrospectively assess how the quality of end-of-life communication with treating physicians was perceived by relatives. We applied multilevel linear and logistic regression models to assess differences between countries and LTCF types.ResultsThe FPPFC score was the lowest in Finland (1.4 ± 0.8) and the highest in Italy (2.2 ± 0.7). In LTCFs served by general practitioners, the FPPFC score differed between countries, but did not in LTCFs with on-site physicians. Most relatives reported that they were well informed about a resident's general condition (from 50.8% in Finland to 90.6% in Italy) and felt listened to (from 53.1% in Finland to 84.9% in Italy) and understood by the physician (from 56.7% in Finland to 85.8% in Italy). In most countries, relatives assessed the worst communication as being about the resident's wishes for medical treatment at the end of life, with the lowest rate of satisfied relatives in Finland (37.6%).ConclusionThe relatives' perception of the quality of end-of-life communication with physicians differs between countries. However, in all countries, physicians' communication needs to be improved, especially regarding resident's wishes for medical care at the end of life.ImplicationsTraining in end-of-life communication to physicians providing care for LTCF residents is recommended.     

Adverse events due to unnecessary radiation exposure in medical imaging reported in Finland

IntroductionAdverse events in radiology are quite rare, but they do occur. Radiation safety regulations and the law obligate organizations to report certain adverse events, harm and near misses, especially events related to patients' health and safety. The aim of this study was to describe and analyse incidents related to radiation safety issues reported in Finland.MethodsThe data were collected from incident reports documented by radiology personnel concerning notifications of abnormal events in medical imaging made to the Radiation and Nuclear Safety Authority between 2010 and 2017. During these eight years, 312 reports were submitted. Only events reported from radiology departments were included; nuclear medicine, radiotherapy and animal radiology cases were excluded. The final number of reports was 293 (94%).ResultsThe majority of the 293 approved reports were related to computed tomography (CT, 68.3%) and to X-ray examinations (27.6%). Altogether 82.9% of those irradiated were adults, most of whom were exposed to unnecessary radiation through CT (86.5%), 5.5% were children, and 4.4% pregnant women. The most common effective dose of unnecessary radiation was 1 mSv or less (89.7% of all examinations). The highest effective doses were reported in CT (from under 1 mSv–20 mSv and above). The reasons for the adverse events were incorrect identification (32%), incorrect procedure, site or side (30%); and human errors or errors of knowledge (20%).ConclusionAdverse events occurred especially in CT examinations. It is important to collect and analyse incident data, assess the harmful events, learn from them and aim to reduce adverse events.Implications for practiceThis study emphasizes the need for radiological personnel to obtain evidence-based information on adverse events and focus on training to improve patient safety.     

肝细胞核因子-κB异常激活与肝细胞癌变

核因子-κB（nuclear factor-κB，NF-κB）是具有和某些基因上启动子区固定核苷酸序列结合而启动该基因转录的蛋白质。NF-κB是具有多向性调节作用的核转录因子，可调控多种基因（免疫、炎症反应、病毒和原癌基因）的转录表达。激活的NF-κB参与癌症的启动、发生及发展过程，在炎症性相关的肝癌（HCC）发生发展中呈高表达，在肝细胞炎症与癌变间起桥梁作用，其中包括肝脏免疫炎症反应相关基因、肝炎病毒相关基因和原癌基因的转录表达。在肝癌组织中异常激活，可抑制细胞凋亡，促进肝细胞存活，与肝癌的发生发展密切相关。     

Concerns for medical radiation programs in Australian universities

The Australian higher education system is in a state of great change. The Federal education minister, Dr Brendan Nelson, has indicated that he intends to continue introducing far-reaching reforms that will impact significantly on how universities conduct teaching and research. The future allocation of government funding for university programs, including those in medical radiation, will have a significant effect on how those programs are delivered and could even determine whether programs remain viable. There will be a financial imperative for academic departments to strengthen research activity and to obtain funding from non-government sources, such as full-fee paying students, in order to generate enough income to cover program delivery. Medical radiation education in Australia is also facing many other challenges. Some of these are longstanding, such as the high cost of medical radiation program delivery, poor levels of research activity and difficulty in recruiting and retaining academic staff. Other problems have arisen recently, such as increased competition for students and a critical shortage of available training placements in clinical practice. The aim of this paper is to raise and explore these issues from a university perspective.

人脑外伤后皮层核因子-κB的表达

目的 探讨核因子-κB（nuclear factor—κB，NF—κB）在人创伤性脑损伤（traumatic brain injury，TBI）后挫伤皮层中的表达情况，包括表达位置、表达强度和表达时相。方法 挫伤区皮层的标本来自24例TBI患者，取样时间为伤后5h-5d，利用凝胶电泳迁移分析法（electrophoretic mobility shift assay，EMSA）和免疫组化技术测定NF—κB的活性和表达强度。结果 在人TBI后的挫伤区皮层中，NF—κB表达明显上调，表达高峰为伤后48—72h，NF—κBP65主要在血管内皮细胞和神经胶质细胞中表达，NF—κBP50主要在神经胶质细胞和少量神经元中表达，NF—κBP65的表达强度高于NF—κBP50。结论 NF—κB在人TBI后的挫伤区皮层中表达上调，提示其可能在TBI后的病理生理过程中起着重要作用。     

Image technique optimization in MR imaging of a titanium alloy joint prosthesis

The purpose of this study was to explore systematically the effect of the imaging parameters changeable by the user in spin-echo (SE) imaging sequences to minimize image distortion when imaging joint prostheses. A titanium alloy hip joint prosthesis was studied at 1.0 T. The SE imaging parameters were bandwidth/pixel (BW/p), TE, strength of encoding gradients (matrix size), echo train length (ETL), and direction of phase and frequency encoding. The effect of ETL in rapid acquisition relaxation enhanced (RARE) sequences was also evaluated with a turbo-SE sequence using a different ETL with the same TR and an effective TE. It is concluded that an optimized image quality can be achieved in SE imaging by using a high bandwidth/pixel value (at least 130 Hz/pixel), a high resolution matrix (256–512), sequences with multiple refocusing, and a frequency-encoding axis parallel to the long axis of the prosthesis. The degree of distortion is reduced with this optimized technique.
