Background: The association between subjective cognitive fatigue and objective cognitive dysfunction in patients with multiple sclerosis (PwMS) has been studied, with conflicting results. Objective: To explore the impact of fatigue on cognitive function, while controlling for the influence of depression, disability, comorbidities, and psychotropic medications. Methods: PwMS completed a computerized cognitive testing battery with age- and education-adjusted cognitive domain scores. Disability (Expanded Disability Status Scale (EDSS)), cognitive fatigue, and depression were concurrently evaluated. Results: In all, 699 PwMS were included. Both cognitive fatigue and depression were significantly and negatively correlated with the same cognitive domains: information processing speed, executive function, attention, motor function, and memory (−0.15 ⩽ r ⩽ −0.14 for cognitive fatigue; −0.24 ⩽ r ⩽ −0.19 for depression). Multivariate analysis revealed significant but small independent correlations only between depression and neuropsychological test results, while cognitive fatigue had no independent correlation with objective cognitive function except for a trend toward impaired motor function in highly fatigued PwMS. Depression and cognitive fatigue accounted for no more than 6% of the variance in objective cognitive domain scores. Conclusion: Cognitive fatigue is not independently related to objective cognitive impairment. Depression may influence cognitive function of PwMS primarily when it is severe. Cognitive impairment in PwMS should not be ascribed to fatigue or mild depression.

Published: February 2017

Objective:This study aimed at validating photoplethysmography for assessing bilateral blood pressure differences through investigating the correlations of digital volume pulse with arteriosclerosis risk.Methods:Totally, 111 subjects (70 healthy and 41 diabetic) were recruited. Demographic, blood pressure and anthropometric data were recorded. Blood was collected for determining serum cholesterol, total triglyceride, total cholesterol, high-/low-density lipoprotein cholesterol, fasting blood sugar and glycated haemoglobin concentrations. Arterial stiffness was assessed with electrocardiogram-based pulse wave velocity, crest time and inter-digital volume pulse differences.Results:Receiver operating characteristic curve demonstrated high inter-digital volume pulse difference sensitivity to glycated haemoglobin level over 6.5%. Linear regression analysis demonstrated significant correlation between inter-digital volume pulse difference and electrocardiogram-based pulse wave velocity ( r = 0.692, p < 0.001). Compared with electrocardiogram-based pulse wave velocity, inter-digital volume pulse difference exhibited highly significant correlations with age, glycated haemoglobin level, pulse pressure, total cholesterol/high-density lipoprotein ratio, crest time, high-density lipoprotein and systolic blood pressure (all ps < 0.001).Conclusion:In conclusion, the results not only demonstrated successful application of a novel non-invasive waveform contour index, inter-digital volume pulse difference, in differentiating young from aged subjects and patients with good diabetic control from those with poor diabetic control but also validated its use in identifying arteriosclerosis risks. The results, therefore, endorse its domestic application as non-invasive tool for arteriosclerosis risk screening.

Background Stroke outcomes can differ by women’s legal or socioeconomic status. Aim We investigated whether differences in women’s rights or gender inequalities were associated with stroke mortality at the country-level. Methods We used age-standardized stroke mortality data from 2008 obtained from the World Health Organization. We compared female-to-male stroke mortality ratio and stroke mortality rates in women and men between countries according to 50 indices of women’s rights from Women, Business and the Law 2016 and Gender Inequality Index from the Human Development Report by the United Nations Development Programme. We also compared stroke mortality rate and income at the country-level. Results In our study, 176 countries with data available on stroke mortality rate in 2008 and indices of women’s rights were included. There were 46 (26.1%) countries where stroke mortality in women was higher than stroke mortality in men. Among them, 29 (63%) countries were located in Sub-Saharan African region. After adjusting by country income level, higher female-to-male stroke mortality ratio was associated with 14 indices of women’s rights, including differences in getting a job or opening a bank account, existence of domestic violence legislation, and inequalities in ownership right to property. Moreover, there was a higher female-to-male stroke mortality ratio among countries with higher Gender Inequality Index (r = 0.397, p < 0.001). Gender Inequality Index was more likely to be associated with stroke mortality rate in women than that in men (p < 0.001). Conclusions Our study suggested that the gender inequality status is associated with women’s stroke outcomes.

Published: February 2017

We report the outcomes of ulnar head replacement with concomitant resurfacing of the sigmoid notch with a lateral meniscal allograft that attempted to recreate the palmar and dorsal radioulnar ligaments in four patients. Patients’ ranges of motion, grip strength, postoperative complications and radiographs were assessed. The mean follow-up was 20 (range 12–28) months. There was an increase in postoperative range of motion with an average increase in grip strength of 43% to the unaffected extremity. All patients experienced marked reduction in their postoperative pain. No patients reported symptoms of implant instability. Distal ulna implant arthroplasty with a lateral meniscal allograft gives favourable short-term outcomes. Level of evidence: IV

Published: February 2017

Objective: People with diabetic peripheral neuropathy (DPN) often exhibit deteriorations in motor-performance mainly due to lack of plantar-sensation. The study explored effectiveness of plantar electrical-stimulation therapy to enhance motor-performance among people with DPN. Design and methods: Using a double-blinded model, 28 volunteers with DPN (age: 57.8 ± 10.2 years) were recruited and randomized to either intervention (IG: n = 17) or control (CG: n = 11) group. Both groups received identical plantar-stimulation devices for six weeks of daily use at home; however, only the IG devices were set to deliver stimulation. Balance (ankle, hip, and center of mass [COM] sway) and gait (stride velocity [SV], stride time [ST], stride length [SL], and cadence) were measured using validated wearable sensors. Outcomes were assessed at baseline and at six-week. Clinical assessment including vascular as measured by ankle-brachial-index (ABI) and plantar-sensation as quantified by vibratory plantar threshold (VPT) were also measured at baseline and six weeks. Results: No difference were observed between groups for baseline characteristics ( P > .050). Posttherapy, ankle and COM sway with eyes open were significantly improved ( P < .05, Cohen’s effect size d = 0.67-0.76) in the IG with no noticeable changes in CG. All gait parameters were significantly improved in the IG with highest effect size observed for cadence ( d = 1.35, P = .000). Results revealed improvement in VPT ( P = .004, d = 1.15) with significant correlation with stride velocity improvement ( r = .56, P = .037). ABI was improved in the IG in particulate among those with ABI>1.20 ( P = .041, d = 0.99) Conclusion: This study suggests that daily home use of plantar electrical-stimulation may be a practical means to enhance motor-performance and plantar-sensation in people with DPN.
The Diagnostic Utility of Computer-Assisted Auscultation for the Early Detection of Cardiac Murmurs of Structural Origin in the Periodic Health Evaluation
Authors: Viviers Pierre L. , Kirby Jo-Anne H. , Viljoen Jeandré T. , Derman Wayne 
Published: February 2017

Background: Identification of the nature of cardiac murmurs during the periodic health evaluation (PHE) of athletes is challenging due to the difficulty in distinguishing between murmurs of physiological or structural origin. Previously, computer-assisted auscultation (CAA) has shown promise to support appropriate referrals in the nonathlete pediatric population. Hypothesis: CAA has the ability to accurately detect cardiac murmurs of structural origin during a PHE in collegiate athletes. Study Design: Cross-sectional, descriptive study. Level of Evidence: Level 3. Methods: A total of 131 collegiate athletes (104 men, 28 women; mean age, 20 ± 2 years) completed a sports physician (SP)–driven PHE consisting of a cardiac history questionnaire and a physical examination. An independent CAA assessment was performed by a technician who was blinded to the SP findings. Athletes with suspected structural murmurs or other clinical reasons for concern were referred to a cardiologist for confirmatory echocardiography (EC). Results: Twenty-five athletes were referred for further investigation (17 murmurs, 6 abnormal electrocardiographs, 1 displaced apex, and 1 possible case of Marfan syndrome). EC confirmed 3 structural and 22 physiological murmurs. The SP flagged 5 individuals with possible underlying structural pathology; 2 of these murmurs were confirmed as structural in nature. Fourteen murmurs were referred by CAA; 3 of these were confirmed as structural in origin by EC. One such murmur was not detected by the SP, however, and detected by CAA. The sensitivity of CAA was 100% compared with 66.7% shown by the SP, while specificity was 50% and 66.7%, respectively. Conclusion: CAA shows potential to be a feasible adjunct for improving the identification of structural murmurs in the athlete population. Over-referral by CAA for EC requires further investigation and possible refinements to the current algorithm. Further studies are needed to determine the true sensitivity, specificity, and cost efficacy of the device among the athletic population. Clinical Relevance: CAA may be a useful cardiac screening adjunct during the PHE of athletes, particularly as it may guide appropriate referral of suspected structural murmurs for further investigation.

Objectives: To investigate whether content from patient narratives explains variation in patients’ primary care provider (PCP) ratings beyond information from the closed-ended questions of the Consumer Assessment of Healthcare Providers and Systems (CAHPS) Clinician and Group Survey and whether the relative placement of closed- and open-ended survey questions affects either the content of narratives or the CAHPS composite scores. Methods: Members of a standing Internet panel (N = 332) were randomly assigned to complete a CAHPS survey that was either preceded or followed by a set of open-ended questions about how well their PCP meets their expectations and how they relate to their PCP. Results: Narrative content from healthier patients explained only an additional 2% beyond the variation in provider ratings explained by CAHPS composite measures. Among sicker patients, narrative content explained an additional 10% of the variation. The relative placement of closed- and open-ended questions had little impact on narratives or CAHPS scores. Conclusion: Incorporating a protocol for eliciting narratives into a patient experience survey results in minimal distortion of patient feedback. Narratives from sicker patients help explain variation in provider ratings.

Published: February 2017

Introduction The overall aim of the present study was to explore perceived life satisfaction in persons with stroke, from admission to specialised rehabilitation until follow up 1 year post-discharge. The secondary aim was to evaluate possible external and internal explanatory factors for perceived life satisfaction. Patients and methods A prospective, descriptive study of specialised rehabilitation of persons with stroke. Persons with a primary diagnosis of stroke were enrolled in the study. Results Overall, total score on LiSat-11 showed that life was perceived as satisfying by 11% on admission, 21% at discharge, 25% at 6 and 31% at 12 months after discharge from rehabilitation, reported by 230 participating persons with stroke. Repeated measurement indicated significant differences of total life satisfaction between clinics, also when controlled for disability and severity. The items “sexual life,” “health,” and “vocational life”/“financial” were most dissatisfying at the various reported time points. The linear regression analysis revealed an equal amount of internal and external explanatory factors at the different time points, explaining between 16% and 41% of the variations. Discussion and conclusion The perceived life satisfaction was reported as low/dissatisfying at the four stated time points in all the participating clinics. Four items were especially vulnerable post-stroke: vocational situation, sexual life, physical health and mental health. Both internal and external factors contributed to life satisfaction, such as gender, severity of stroke, marital status, country, models of rehabilitation, occupational status, length of stay (LOS), number of therapies and hours in therapy. However, there were significant differences between clinics, indicating that unidentified factors may also influence life satisfaction.

Key Points
The RNA regulators PUMILIO sustain HSPC and acute myeloid leukemia cell growth by upregulating FOXP1 expression through direct binding to 2 FOXP1-3′UTR PUMILIO-binding elements. FOXP1 mediates PUMILIO growth-promoting activities by repressing expression of p21CIP1 and p27KIP1cell cycle inhibitors.

The prevalence of idiopathic pulmonary fibrosis (IPF), a fatal and progressive lung disease, is estimated at 1.25–63 out of 100 000, making large population studies difficult. Recently, the need for large longitudinal registries to study IPF has been recognised.The Australian IPF Registry (AIPFR) is a national registry collating comprehensive longitudinal data of IPF patients across Australia. We explored the characteristics of this IPF cohort and the effect of demographic and physiological parameters and specific management on mortality.Participants in the AIPFR (n=647, mean age 70.9±8.5 years, 67.7% male, median follow up 2 years, range 6 months–4.5 years) displayed a wide range of age, disease severity and co-morbidities that is not present in clinical trial cohorts. The cumulative mortality rate in year one, two, three and four was 5%, 24%, 37% and 44% respectively. Baseline lung function (forced vital capacity, diffusing capacity of the lung for carbon monoxide, composite physiological index) and GAP (gender, age, physiology) stage (hazard ratio 4.64, 95% CI 3.33–6.47, p<0.001) were strong predictors of mortality. Patients receiving anti-fibrotic medications had better survival (hazard ratio 0.56, 95% CI 0.34–0.92, p=0.022) than those not on anti-fibrotic medications, independent of underlying disease severity.The AIPFR provides important insights into the understanding of the natural history and clinical management of IPF.
Is the lower return to immigrants’ foreign schooling a postarrival problem in Canada?
Authors: Aydede Yigit , Dar Atul 
Published: February 2017

AbstractUsing the 2006 Canadian Census, this paper investigates the lower return to immigrants’ foreign education credentials after adjusting for their occupational matching in hosting labor markets. We develop two continuous indices that quantify the matching quality of the native-born in both horizontal (fields of study) and vertical (educational degrees) dimensions. This allows us to separate the effects of immigrants’ occupational attainment and their foreign schooling quality on wage earnings by measuring immigrants’ occupational match relative to that of native-born. Our findings indicate that the lack of portability in immigrants’ foreign credentials may not be addressed effectively by postarrival policies as the results show that a significant and persistent poor matching quality for internationally educated immigrants cannot substantiate the lower return to their foreign education credentials.JEL Classification:J6, J15, J61
Graphs to estimate an individualized risk of breast cancer.
Authors: Benichou J , Gail M H , Mulvihill J J 
Published: February 2017

PURPOSE Clinicians who counsel women about their risk for developing breast cancer need a rapid method to estimate individualized risk (absolute risk), as well as the confidence limits around that point. The Breast Cancer Detection Demonstration Project (BCDDP) model (sometimes called the Gail model) assumes no genetic model and simultaneously incorporates five risk factors, but involves cumbersome calculations and interpolations. This report provides graphs to estimate the absolute risk of breast cancer from the BCDDP model. PATIENTS AND METHODS The BCDDP recruited 280,000 women from 1973 to 1980 who were monitored for 5 years. From this cohort, 2,852 white women developed breast cancer and 3,146 controls were selected, all with complete risk-factor information. The BCDDP model, previously developed from these data, was used to prepare graphs that relate a specific summary relative-risk estimate to the absolute risk of developing breast cancer over intervals of 10, 20, and 30 years. RESULTS Once a summary relative risk is calculated, the appropriate graph is chosen that shows the 10-, 20-, or 30-year absolute risk of developing breast cancer. A separate graph gives the 95% confidence limits around the point estimate of absolute risk. Once a clinician rules out a single gene trait that predisposes to breast cancer and elicits information on age and four risk factors, the tables and figures permit an estimation of a women's absolute risk of developing breast cancer in the next three decades. CONCLUSION These results are intended to be applied to women who undergo regular screening. They should be used only in a formal counseling program to maximize a woman's understanding of the estimates and the proper use of them.

PURPOSE We conducted a randomized trial to investigate the value of the addition of cisplatin to teniposide (VM26) and to investigate the schedule dependence of the topoisomerase II inhibitor VM26, in advanced non-small-cell lung cancer (NSCLC) patients. PATIENTS AND METHODS Two hundred twenty-five NSCLC patients were randomized to receive VM26 120 mg/m2 on days 1, 3, and 5 or 360 mg/m2 on day 1 only, either as a single drug or in combination with cisplatin 80 mg/m2 on day 1. Cycles were repeated every 3 weeks. Response rates, side effects, and survival were compared according to the 2 x 2 factorial design of this study. RESULTS The response rate of the two cisplatin-containing arms was superior to that of the two arms that contained VM26 only (22% v 6%, P < .001); progression-free survival and survival times were also longer in the cisplatin-containing arms (median, 4.3 v 2.2 months, P = .003; median 7.2 v 5.9 months, P = .008, respectively). Toxicity was significantly higher in the cisplatin-containing arms; the most frequent side effects were leukopenia, nausea and vomiting, and alopecia. The schedule of VM26 did not significantly influence the response rate, progression-free survival interval, or survival duration. However, the response rate of the 1-day administration was significantly lower than that of the 3-day administration when given as single drugs. CONCLUSION The addition of cisplatin to VM26 improves the response rate, progression-free survival interval, and survival duration over VM26 alone, although at the cost of a significant increase in toxicity. Cisplatin should be considered as the basis for combination chemotherapies in advanced NSCLC.
