ObjectivesThe primary objective of this paper is to examine terrain park (TP) feature compliance with recommendations from a ski area industry guide (are TP features compliant with the guide?) and determine factors that could be associated with TP feature compliance in Québec ski areas (do factors influence TP feature compliance?), Canada. These recommendations on the design, construction and maintenance are provided by the Québec Ski Areas Association Guide.MethodsA group of two to four trained research assistants visited seven ski areas. They used an evaluation tool to assess the compliance of 59 TP features. The evaluation tool, originally developed to assess the quality of TP features based on the guide, was validated in a previous study. Compliance was calculated by the percentage of compliant measures within a given feature. The potential influence of four factors on compliance (size of the TP, size of the feature, snow conditions and type of feature) were examined using a mixed-effects logistic regression model.ResultsThe average TP feature compliance percentage was 93% (95% CI 88% to 99%) for boxes, 91% (95% CI 89% to 94%) for rails and 89% (95% CI 86% to 92%) for jumps. The logistic regression showed that none of the four factors examined were associated with TP feature compliance with the guide.ConclusionOur results suggest that TP features are highly compliant with the guide in Québec ski areas.

This study is a quantitative analysis designed to compare two groups of factually innocent capital defendants: those who were exonerated and those who were executed. There are a total of 97 cases in the sample, including 81 exonerations and 16 executions. The primary objective of the authors is to identify factors that may predict case outcomes among capital defendants with strong claims of factual innocence. Through the use of a logistic regression model, the following variables were significant predictors of case outcome (exoneration vs. execution): allegations of perjury, multiple types of evidence, prior felony record, type of attorney at trial, and race of the defendant. These results point toward significant problems with the administration of capital punishment deriving primarily from the quality of the case record created at trial.

The implementation of alternative techniques in urban stormwater management is a difficult problem in terms of choice, design, construction, and operating. We applied a quality management approach to try and have a better understanding of these techniques. The quality of an alternative technique in urban stormwater management is defined; the factors that lead to failures were identified and analysed. In order to reduce these factors, tools were developed, and measures that allow the achievement of the necessary standard of quality are suggested. In this article, all the illustrations refer to the porous pavement technique.

Abstract Background The etiology of reflux esophagitis (RE) is multi-factorial. This study analyzed the relationship of depression, anxiety, lifestyle and eating habits with RE and its severity and further explored the impact of anxiety and depression on patients’ symptoms and quality of life. Methods From September 2016 to February 2018, a total of 689 subjects at Xuanwu Hospital Capital Medical University participated in this survey. They were divided into the RE group (patients diagnosed with RE on gastroscopy, n = 361) and the control group (healthy individuals without heartburn, regurgitation and other gastrointestinal symptoms, n = 328). The survey included general demographic information, lifestyle habits, eating habits, comorbidities, current medications, the gastroesophageal reflux disease (GERD) questionnaire (GerdQ), the Patient Health Questionnaire-9 depression scale and the General Anxiety Disorder-7 anxiety scale. Results The mean age and sex ratio of the two groups were similar. Multivariate logistic regression analysis identified the following factors as related to the onset of RE (p < 0.05): low education level; drinking strong tea; preferences for sweets, noodles and acidic foods; sleeping on a low pillow; overeating; a short interval between dinner and sleep; anxiety; depression; constipation; history of hypertension; and use of oral calcium channel blockers. Ordinal logistic regression analysis revealed a positive correlation between sleeping on a low pillow and RE severity (p = 0.025). Depression had a positive correlation with the severity of symptoms (rs = 0.375, p < 0.001) and patients’ quality of life (rs = 0.306, p < 0.001), whereas anxiety showed no such association. Conclusions Many lifestyle factors and eating habits were correlated with the onset of RE. Notably, sleeping on a low pillow was positively correlated with RE severity, and depression was positively related to the severity of symptoms and patients’ quality of life.

Abstract Background There is a growing interest in assessment of the quality of hospital care, based on outcome measures. Many quality of care comparisons rely on binary outcomes, for example mortality rates. Due to low numbers, the observed differences in outcome are partly subject to chance. We aimed to quantify the gain in efficiency by ordinal instead of binary outcome analyses for hospital comparisons. We analyzed patients with traumatic brain injury (TBI) and stroke as examples. Methods We sampled patients from two trials. We simulated ordinal and dichotomous outcomes based on the modified Rankin Scale (stroke) and Glasgow Outcome Scale (TBI) in scenarios with and without true differences between hospitals in outcome. The potential efficiency gain of ordinal outcomes, analyzed with ordinal logistic regression, compared to dichotomous outcomes, analyzed with binary logistic regression was expressed as the possible reduction in sample size while keeping the same statistical power to detect outliers. Results In the IMPACT study (9578 patients in 265 hospitals, mean number of patients per hospital = 36), the analysis of the ordinal scale rather than the dichotomized scale (‘unfavorable outcome’), allowed for up to 32% less patients in the analysis without a loss of power. In the PRACTISE trial (1657 patients in 12 hospitals, mean number of patients per hospital = 138), ordinal analysis allowed for 13% less patients. Compared to mortality, ordinal outcome analyses allowed for up to 37 to 63% less patients. Conclusions Ordinal analyses provide the statistical power of substantially larger studies which have been analyzed with dichotomization of endpoints. We advise to exploit ordinal outcome measures for hospital comparisons, in order to increase efficiency in quality of care measurements. Trial registration We do not report the results of a health care intervention.

Background:Ankylosing spondylitis (AS) is a systemic chronic inflammatory disease, which most likely occurs in young men. It mainly affects sacroiliac joints, axial skeleton, thoracic cage and seriously decreasing quality of life in AS patients[1,2]. In recent years, fatigue of AS patients has been paid more and more attention[3]. Fatigue is a complex feeling, diseased individuals describe fatigue as a sense of tiredness at rest, exhaustion with activity, lack of energy which affects daily work, inertia or lack of endurance, or as loss of vitality. It has been confirmed that fatigue is not only a symptom but may also be quantified by fatigue scores and can be modified by various measures depending on the underlying cause[4]. However, there has been no study about fatigue in AS patients in China.Objectives:This study aimed to evaluate the predictors of fatigue and the effects of fatigue on HR-QoL among patients with AS.Methods:A total of 150 AS patients were involved in the study. A series of questionnaires included: Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), Bath Ankylosing Spondylitis Metrology Index (BASMI), Bath Ankylosing Spondylitis Functional Index (BASFI), the 10 cm Visual Analog Scale (VAS), the Self-Rating Anxiety Scale (SAS), the Self-Rating Depression Scale (SDS), the Pittsburgh Sleep Quality Index (PSQI), the Health Assessment Questionnaire-Disability Index (HAQ-DI), the Short Form 36 Health Survey (SF-36) and the Fatigue Severity Scale(FSS). Independent samples t-test, Mann–Whitney U-test, Chi-square analysis, Pearson /Spearman correlation and binary logistic regression were used to analyze the data.Results:The results demonstrated that 48.7% individuals with AS suffered from fatigue. Compared with AS patients without fatigue, AS patients with fatigue showed higher WHR(P<0.05), increased BASDAI (P<0.01) and poorer BASFI (P<0.05). Meanwhile, AS patients with fatigue tended to have more severe pain(P<0.05), higher degree of anxiety(P=0.001), more serious functional disability(P=0.001) and worse sleep quality(P=0.001). Binary logistic regression indicated that WHR (OR=1.78,P<0.05), BASDAI (OR=1.34,P=0.01), sleep disturbance (OR=2.35,P<0.05) were independent predictors of fatigue in AS patients. Additionally, the occurrence of fatigue significantly reduced the quality of life in AS patients both physically and psychologically.Conclusion:These findings suggested that medical personnel should pay more attention to AS patients with fatigue and take effective measures to relieve fatigue.References:[1]Law L, Beckman Rehnman J, Deminger A, Klingberg E, Jacobsson LTH, Forsblad-d’Elia H (2018) Factors related to health-related quality of life in ankylosing spondylitis, overall and stratified by sex.

Abstract INTRODUCTION This study presents the first steps and results towards the development of a system for predicting the quality of surgical performance and workload in laparoscopic training. MATERIAL AND METHODS Surgeons wore a smartwatch which recorded their heart rate and hand motion during each laparoscopic procedure. Data was then correlated with both the Surgery Task Load Index (SURG-TLX) subjective questionnaire and the Global Operational Assessment of Laparoscopic Skills (GOALS) objective evaluation tool. Statistical analysis was conducted in order to study the relationship between parameters and to compare the results according to the surgeons’ level of experience. RESULTS Nine laparoscopic surgeons participated in this study, five gynecologists and four digestive surgeons. Gynecological surgeons showed a positive correlation between their level of experience, heart rate, hand motion, and GOALS score, except for bimanual dexterity. The reduction in the variability of hand accelerations led to improved tissue handling. Digestive surgeons showed a negative correlation between their level of experience and the reported temporal demand and complexity of the procedure. Novice digestive surgeons reported increased workload during surgery, mainly in mental, physical, and temporal workload. In both surgical specialties, it was observed that reduction in surgical workload was associated with improved GOALS score. CONCLUSIONS Preliminary results showed that bimanual dexterity is independent of the experience of gynecological surgeons. During laparoscopic surgical procedures, reduced variability in hand accelerations leads to better tissue manipulation. In addition, in gynecological and upper gastrointestinal procedures, reduced surgical workload is associated with improved surgical performance.

Technical Developments

Cities are exposed to a growing complexity, diversity and rapid socio-technical developments. One of the greatest challenges is as of how to become fully inclusive to fit the needs of all their citizens, including those with disabilities. Inclusive city, both in theory and practice, still lacks attention. Even in the context of ambitious contemporary concepts, such as smart and sustainable city, the question remains: Do smart and sustainable cities consider inclusiveness of all their inhabitants? Among numerous evaluation systems that measure city’s smartness, sustainability or quality of life, those tackling inclusion are very rare. Specifically, disability inclusion is hardly covered. This may be one of the reasons why cities struggle with applying disability inclusion to practice in a holistic and integrative way. This paper proposes a Disability Inclusion Evaluation Tool (DIETool) and Disability Inclusion Performance Index (DIPI), designed to guide cities through a maze of accessibility and disability inclusion related requirements set within the political, legislative and standardization frameworks. The testing in two European cities shows that the tool is beneficial for providing diagnosis as to how disability friendly a city is, and as such offers an opportunity for designing informed corrective measures towards disability inclusive city design.

Objective The study aimed to explore physician views on whether extremely early newborns will have an acceptable quality of life (QOL), and if these views are associated with physician resuscitation preferences. Study Design We performed a cross-sectional survey of neonatologists and maternal fetal medicine (MFM) attendings, fellows, and residents at four U.S. medical centers exploring physician views on future QOL of extremely early newborns and physician resuscitation preferences. Mixed-effects logistic regression models examined association of perceived QOL and resuscitation preferences when adjusting for specialty, level of training, gender, and experience with ex-premature infants. Results A total of 254 of 544 (47%) physicians were responded. A minority of physicians had interacted with surviving extremely early newborns when they were ≥3 years old (23% of physicians in pediatrics/neonatology and 6% in obstetrics/MFM). The majority of physicians did not believe an extremely early newborn would have an acceptable QOL at the earliest gestational ages (11% at 22 and 23% at 23 weeks). The majority of physicians (73%) believed that having an extremely preterm infant would have negative effects on the family's QOL. Mixed-effects logistic regression models (odds ratio [OR], 95% confidence interval [CI]) revealed that physicians who believed infants would have an acceptable QOL were less likely to offer comfort care only at 22 (OR: 0.19, 95% CI: 0.05–0.65, p < 0.01) and 23 weeks (OR: 0.24, 95% CI: 0.07–0.78, p < 0.02). They were also more likely to offer active treatment only at 24 weeks (OR: 9.66, 95% CI: 2.56–38.87, p < 0.01) and 25 weeks (OR: 19.51, 95% CI: 3.33–126.72, p < 0.01). Conclusion Physician views of extremely early newborns' future QOL correlated with self-reported resuscitation preferences. Residents and obstetric physicians reported more pessimistic views on QOL.

The Impact

Purpose: The primary objective of this study was to quantify cancer family caregiver (FCG) quality of life (QOL) in a Southern Albanian population and to determine whether differences exist between 4 domains of QOL (physical, psychological, social, and spiritual). This study also sought to compare QOL in our cohort to QOL in historical studies that used the same survey instrument, and to examine correlations between demographic characteristics and QOL to identify any high-risk groups. Methods: A sample of 40 FCGs was recruited at the Mary Potter Palliative Care Clinic in Korçe, Albania. Each participant completed the City of Hope Quality of Life (Family Version), a validated 37-question instrument that measures caregiver well-being in 4 domains: physical, psychological, social, and spiritual well-being. Results: There were no significant differences between the composite scores of the 4 QOL domains in our study. However, there were differences when comparing self-reported QOL between domains (“Rate your overall physical/psychological/social/spiritual well-being”). The QOL measured in our study was significantly lower than in 3 studies from the United States that used the same questionnaire. There were no significant correlations between demographic groups and QOL. Conclusions: This study examines the impact that the paucity of palliative services has on the QOL of Albanian cancer FCGs. Although there were no domains of QOL or demographic groups identified in our study that were faring significantly worse than others, the poor overall QOL provides further evidence to support the continued development of palliative services for both patients and family members in Albania.
