Impact of donor preprocurement cardiac arrest on clinical outcomes in pediatric deceased donor liver transplantation

PPCA has historically been considered detrimental to donor quality in LT, but transplantation of grafts from this group of donors is now routine. Our study aims to evaluate the outcomes associated with use of donors with a history of PPCA in the pediatric population. This study is a single‐center retrospective analysis of all pediatric LTs performed over an 18‐year period. Donors and recipients were stratified by the presence and length of donor PPCA time. Preprocurement donor and post‐transplant recipient laboratory values were collected to assess the degree of ischemic liver injury associated with each donor group. Cox regression analysis was used to compare survival. The records for 130 deceased pediatric LT donors and corresponding recipients were reviewed. There were 73 (56%) non‐PPCA donors and 57 (44%) PPCA donors. Donors that experienced a PPCA event demonstrated a higher median, pretransplant peak alanine aminotransferase (ALT) level (P < .001). When comparing post‐transplant recipient median ALT levels, donors with any PPCA had lower median peak ALT (P = .15) and day 3 ALT (P = .43) levels than the non‐PPCA group. Rates of early graft loss did not differ. The PPCA group with >40 minutes of ischemia had markedly lower survival at 10 years, but this finding did not reach statistical significance. Liver grafts from donors with or without PPCA demonstrated no statistically significant differences in function or survival. A history of donor PPCA alone should not be used as an exclusionary criterion in pediatric liver transplantation.

某校大学生饮食习惯对肠易激综合征的影响

目的 了解饮食对肠易激综合征的影响。方法 对2018年10月—2019年4月来校医院就诊的1 207名在校本科生进行问卷调查,问卷依据罗马Ⅳ诊断标准,数据分析采用SPSS 22.0卡方检验、单因素分析、Logistic多因素回归分析。结果 来校医院就诊的在校大学生中,肠易激综合征的患病率为5.1%(60/1207)。在单因素分析中,进食生冷(P=0.070)、高纤维(P=0.367)、乳制品(P=0.414)、果蔬(P=0.784)与肠易激综合征的患病差异无统计学意义。进食辛辣(P=0.002)、高脂饮食(P<0.001)与肠易激综合征的患病差异有统计学意义。进一步Logistic多因素回归分析显示,高频率进食高脂食物比低频率(≤1次/周)进食高脂食物更容易引起肠易激综合征。P值为0.003,OR:1.545。结论 本调查样本中,肠易激综合征的患病率为5.1%。肠易激综合征的患病与进食辛辣、高脂饮食有关。高频率的进食高脂食物是肠易激综合征患病的危险因素。基层医生应着重做好相关病人的饮食指导,尽量减少肠易激综合征被诱发。     

Systematic review: Predictors of students’ success in baccalaureate nursing programs

Nursing schools strive to select a diverse student population who are likely to succeed by ensuring timely student progression through the program and effective use of educational sources. The purpose of this systematic literature review is to explore the preadmission variables and selection criteria that predict student success in 4-year baccalaureate nursing programs in the U.S. Sixteen articles met the eligibility criteria, and six measures were used to define student success: (a) early academic success, particularly during the first and second year; (b) attrition; (c) timely completion of the program; (d) graduation; (e) performance in nursing courses; and (f) academic performance in other science courses. Typically, the core set of cognitive predictors used in the admission process in nursing schools were pre-nursing GPA, pre-nursing collegiate science GPA, and scores on standardized aptitude exams. This review suggests that it is challenging to isolate one single variable as the best predictor of student success; however, using a combination of variables can offer a reliable prediction method. More researchers should consider using a theoretical basis to guide their inquiry on this topic. Additionally, researchers should examine admission variables that are most relevant across programs.     

Hearing Aid–Related Standards and Test Systems

Many documents describe standardized methods and standard equipment requirements in the field of audiology and hearing aids. These standards will ensure a uniform level and a high quality of both the methods and equipment used in audiological work. The standards create the basis for measuring performance in a reproducible manner and independent from how and when and by whom parameters have been measured. This article explains, and focuses on, relevant acoustic and electromagnetic compatibility parameters and describes several test systems available.     

Analyser les procédures et les modalités d’évaluation du handicap à la lumière de la Convention des Nations unies relative aux droits des personnes handicapées : proposition de guide méthodologique

The implementation of the UN Convention on the Rights of Persons with Disabilities (CRDP) implies that signatory States, among other obligations, take the necessary measures to allow persons with disabilities “to live in the community, with choices equal to others” (art. 19). To undertake support services and provisions, development policies promoting social inclusion and participation of disabled persons, international organisations (UN, World Bank, European Disability Forum…) recommend that State parties develop disability assessment mechanisms and eligibility criteria for services and benefits consistent with the Convention. Many countries, notably developing countries, are in need of guiding tools and methods to analyze and reform their disability assessment systems and procedures in light of the Convention. This article presents the results of a research conducted in 2011–2012. Based on articles of the Convention on one hand, on a review of international literature on the definition of disability and disability assessment mechanisms on the other hand, and continuous consultation of disabled persons organisations in seven low and middle income countries (India, Nepal, Uganda, Philippines, Romania, Rwanda and Tunisia) and two OECD countries (Belgium and France), the study resulted in identifying a number of issues related to disability assessment mechanisms and in developing a methodological guide for private and public stakeholders. This guide allows describing and analyzing disability assessment and eligibility mechanisms in a given country, in order to develop indicators with a view to proposing reforms.     

Percutaneous thermal ablation of sacral metastases: Assessment of pain relief and local tumor control

PurposeTo retrospectively report on safety, pain relief and local tumor control achieved with percutaneous ablation of sacral bone metastases.Materials and methodsFrom February 2009 to June 2020, 23 consecutive patients (12 women and 11 men; mean age, 60 ± 8 [SD] years; median, 60; range: 48-80 years) with 23 sacral metastases underwent radiofrequency (RFA) or cryo-ablation (CA), with palliative or curative intent at our institution. Patients’ demographics and data pertaining to treated metastases, procedure-related variables, safety, and clinical evolution following ablation were collected and analyzed. Pain was assessed with numerical pain rating scale (NPRS).ResultsSixteen (70%) patients were treated with palliative and 7 (30%) with curative intent. Mean tumor diameter was 38 ± 19 (SD) mm (median, 36; range: 11-76). External radiation therapy had been performed on five metastases (5/23; 22%) prior to ablation. RFA was used in 9 (39%) metastases and CA in the remaining 14 (61%). Thermo-protective measures and adjuvant bone consolidation were used whilst treating 20 (87%) and 8 (35%) metastases, respectively. Five (22%) minor complications were recorded. At mean 31 ± 21 (SD) (median, 32; range: 2-70) months follow-up mean NPRS was 2 ± 2 (SD) (median, 1; range: 0–6) vs. 5 ± 1 (median, 5; range: 4–8; P < 0.001) at the baseline. Three metastases out of 7 (43%) undergoing curative ablation showed local progression at mean 4 ± 4 (SD) (median, 2; range: 1-8) months follow-up.ConclusionPercutaneous ablation of sacral metastases is safe and results in significant long-lasting pain relief. Local tumor control seems sub-optimal; however, further investigations are needed to confirm these findings due to paucity of data.     

Peculiar lifespan changes of periodic leg movements during sleep in restless legs syndrome

The objective of this observational cohort study was to analyse the age‐related changes of periodic leg movements during sleep using the newest international scoring rules, to expand past analyses, including patients in the paediatric age range, and also to analyse the changes of short‐interval and isolated leg movements during sleep throughout the lifespan. One hundred and sixty‐five patients (84 women) with restless legs syndrome were recruited in the following age groups: 16 preschoolers (≤5 years of age), 29 school‐age children (6–12 years), 19 adolescents (13–17 years), 17 young adults (19–40 years), 47 adults (41–60 years) and 37 seniors (>60 years). Total, periodic, short‐interval and isolated leg movements during sleep and periodicity indexes were obtained by polysomnography. The total index showed (quartic polynomial interpolation) a decrease before 10 years, followed by a steady increase up to 30 years, a relatively stable period until 60 years, and a final increase up to 80 years. This course was almost entirely due to changes in periodic movements. Isolated movements did not change significantly and short‐interval movements showed only an increase in seniors. Our study indicates that, in restless legs syndrome, the total index shows a peculiar and unique course throughout the lifespan, mainly due to periodic movements. These age‐related changes may mirror developmental changes in network complexity known to occur in dopaminergic circuits. These data further confirm the need to better assess the periodicity of leg movements in sleep during the human development period, in order to obtain clinically useful information.
