    Patients with non-transfusion-dependent thalassemia (NTDT) often develop iron overload that requires chelation to levels below the threshold associated with complications. This can take several years in patients with high iron burden, highlighting the value of long-term chelation data. Here, we report the 1-year extension of the THALASSA trial assessing deferasirox in NTDT; patients continued with deferasirox or crossed from placebo to deferasirox. Of 133 patients entering extension, 130 completed. Liver iron concentration (LIC) continued to decrease with deferasirox over 2 years; mean change was -7.14 mg Fe/g dry weight (dw) (mean dose 9.8 ± 3.6 mg/kg/day). In patients originally randomized to placebo, whose LIC had increased by the end of the core study, LIC decreased in the extension with deferasirox with a mean change of -6.66 mg Fe/g dw (baseline to month 24; mean dose in extension 13.7 ± 4.6 mg/kg/day). Of 166 patients enrolled, 64 (38.6 %) and 24 (14.5 %) patients achieved LIC Deferasirox progressively decreases iron overload over 2 years in NTDT patients with both low and high LIC. Safety profile of deferasirox over 2 years was consistent with that in the core study.

    The purpose of this study was to analyze the prevalence, demographic patterns and management of odontogenic infections in patients undergoing treatment in an outpatient dental emergency service of a university hospital. In a retrospective study of the year 2012, all patients suffering from odontogenic infections were included. Demographic data, diagnosis and the conducted treatment were analyzed. Odontogenic infections were defined as pulpitis, apical and marginal periodontitis, abscesses and pericoronitis. A total of 2,058 out of 4,209 emergency patients suffered from odontogenic infections. The majority (45.0%) had an apical periodontitis, 20.8% abscesses, 17.3% a marginal periodontitis, 16.3% a pulpitis and 5.8% a pericoronitis. Mean age was 37.5 ± 17.0 years standard deviation (SD) (1.2-96.4). Most patients were 20 to 29 years (24.6%), followed by the age group of 30 to 39 year old patients (21.0%). Males were affected more frequently (55.5%) than females (45.5%). Most of the patients (64.5%) of the patients received a dental or surgical treatment. Antibiotics were prescribed in 31.7% of cases. Amoxicillin was the most common prescribed antibiotic (54.5%). Odontogenic infections represent one of the main reasons for consulting the emergency service. Due to the high number of cases and the severe complications, dentists have to be familiar with the surgical management of odontogenic infections as well as the appropriate use of antibiotics. Nearly half of all patients who sought, treatment in the emergency service had an odontogenic infectious disease. This should be considered for the organization and planning of the service.

    Full Text Available Purpose: The purpose of this 1-year longitudinal study is to investigate the change in flow experience among occupational therapy students (OTS. Methods: In December 2012, we prospectively recruited 97 OTS from the Department of Occupational Therapy, Kibi International University. To assess flow experience in daily life, we used the Flow Experience Checklist. Results: The dataset included 87 OTS, of which 75 participated in the assessment at 1 year (follow-up rate, 86.2%. The mean age at baseline of 45 male and 30 female OTS was 19.59±1.1 years (range, 18 to 24 years. A comparison of the ‘frequency of flow experience’ showed significant differences between baseline values and those after 1 year (December 2013 among male OTS (P<0.05. Conclusion: The present results indicate that, for male OTS, the frequency of flow was significantly reduced after 1 year compared with baseline values. This finding suggests the need for further education to increase the frequency of flow among male OTS.

    In view of the conflicting guidelines issued by national and international scientific societies, debate about the indications for prophylactic extraction of wisdom teeth is ongoing. This prospective study was therefore set up to explore the complications associated with wisdom teeth and requiring in-patient treatment. From January /2003 to December 2003, 21 subjects were admitted for treatment of complications associated with wisdom teeth. The medical history was recorded for each of these patients, as were the cause and type of the complications. The parameter used to quantify the severity of any infections was the CRP, and the overall clinical complexity level of each case was assessed by the length of stay in hospital (and the duration of intensive care if this had been necessary). The characteristics of patients in the group with postoperative complications were compared to those of patients with complications attributable to pericoronitis. Moreover, complications in patients who had undergone prophylactic extraction of wisdom teeth that had not been causing any symptoms were compared with those in patients whose wisdom teeth had been extracted because of morbidity. Overall, 18 deep-space infections (15 abscesses, 2 inflammatory infiltrations, 1 case of phlegmonous cellulitis), 2 mandibular fractures and 1 lingual nerve injury were noted within 1 year. The complications resulted from surgical procedures in 15 of the 21 cases, while in 6 they had their origin in pericoronitis. Extensive surgery or intensive care was required only for patients with postoperative complications. The length of stay in hospital was significantly greater for patients with postoperative complications ( p= 0.007, U-test). However, 9 of these 15 patients reported preoperative episodes of infection. Thus, more than two thirds of the complications could be traced back to wisdom teeth that were causing symptoms. In our clinic's catchment area, infectious complications were more frequent and

    Osteoporosis is prevalent in men with an estimated one in eight men older than 50 years suffering from osteoporotic fracture, and a higher mortality rate after fracture among men compared with women. There are few approved therapies for osteoporosis in men. This observational study assesses the efficacy and safety of risedronate in the treatment of men with primary and secondary osteoporosis. A single-center, open label, randomized, prospective 1-year study was conducted in men with primary or secondary osteoporosis. Patients were randomized to risedronate (risedronate 5 mg/day plus calcium 1,000 mg/day and vitamin D 800 IU/day) or control groups (alfacalcidol 1 mug/day plus calcium 500 mg/day or vitamin D 1,000 IU/day plus calcium 800 mg/day). Bone mineral density (BMD) measurements, X-rays of the spine, a medical history and physical exam, and patient self-assessments of back pain were performed at baseline and 12 months. Blinded semi-quantitative fracture assessment was conducted by a radiologist. A total of 316 men with osteoporosis were enrolled in the trial (risedronate, n=158; control, n=158). At 1 year lumbar spine BMD increased by 4.7% in the risedronate group versus an increase of 1.0% in the control group (P<0.001). Significant increases in BMD at the total hip and femoral neck were also observed with risedronate compared with the control group. The incidence of new vertebral fracture in the risedronate group was reduced by 60% versus the control group (P=0.028). Daily treatment with risedronate for 12 months significantly increased BMD at the lumbar spine, femoral neck and total hip and significantly reduced the incidence of new vertebral fractures. This is the first prospective, randomized, controlled trial to demonstrate a significant reduction in vertebral fractures in 1 year in men with primary or secondary osteoporosis.

In the last decade, the percentage of older adults who receive health care in nursing homes, day care centers, or home support services has increased in Europe. The objectives of this descriptive and nonrandomized longitudinal study were to evaluate and to compare the cognitive and affective evolution of day care versus institutionalized older patients through a 1-year period, and to assess the presence of cognitive and affective impairment as a function of the care setting.Patients and methods: Ninety-four patients were assessed at baseline, and 63 (67.0% were reassessed 1 year later. Neuropsychological assessment included measures of cognitive performance (general cognitive status, visuospatial, and language abilities and affective status (depressive symptoms.Results: Our findings indicated that the majority of the participants (day care and institutionalized patients had mild–moderate cognitive impairment at baseline, which significantly increased in both groups after 1-year follow-up. However, the rate of change in global cognitive function did not significantly differ between groups over time. Regarding language abilities, naming function maintained among day care patients in comparison with institutionalized patients, who showed worse performance at follow-up. As regards to affective status, results revealed that institutionalized patients had a significant reduction in depressive symptoms at follow-up, when compared to day care patients. Results also highlight the high frequency of cognitive impairment and depressive symptoms regardless of the care setting

    To investigate the etiology and prevalence of optic neuritis in a Chinese population. This was a single centre prospective cohort study. Consecutive patients with either a first or recurrent attack of optic neuritis from November 2010 to December 2011 were recruited from a district hospital in Hong Kong Special Administrative Region, China. All patients underwent serology testing for NMO (neuromyelitis optica) IgG; oligoclonal bands from lumbar puncture; computer tomography and contrast magnetic resonance imaging (MRI) of the brain and orbit as well as visual field; and optical coherence tomography testing. Patients were followed up for 1 year after the initial attack. 30 optic neuritis subjects were recruited. 73.3 % (22/30) remain as clinical isolated syndrome (CIS) after 1-year follow-up. 10 % (3/30) patients developed multiple sclerosis. 10 % (3/30) were diagnosed with NMO and 6.7 % (2/30) with NMO-spectrum disorder. The majority of acute unilateral optic neuritis in Chinese was CIS in origin although a fraction does progress to develop MS or NMO-related disorders. Clinicians should be aware of the associations and offer appropriate systemic workups.

    Two 1-year studies evaluated the long-term efficacy and safety of tiotropium 5 or 10 microg versus placebo, inhaled via the Respimat Soft Mist Inhaler (SMI). The two studies were combined and had 4 co-primary endpoints (trough FEV(1) response, Mahler Transition Dyspnea Index [TDI] and St George's Respiratory Questionnaire scores all at week 48, and COPD exacerbations per patient-year). A total of 1990 patients with COPD participated (mean FEV(1): 1.09 L). The mean trough FEV(1) response of tiotropium 5 or 10 microg relative to placebo was 127 or 150 mL, respectively (both P SMI 5 microg demonstrated sustained improvements in patients with COPD relative to placebo and similar to the 10 microg dose but with a lower frequency of anticholinergic adverse events.

    The incidence of whooping cough in Romania is substantially underestimated, and, as noted by the health authorities, this is mostly due to the lack of both awareness and biological diagnosis. We conducted a 1-year study in Bucharest in order to assess the circulation of Bordetella pertussis, the main etiological agent of whooping cough. Fifty-one subjects suspected of whooping cough were enrolled. Culture, real-time PCR, and enzyme-linked immunosorbent assay were used for laboratory diagnosis. Whooping cough patients (63%) were distributed among all age groups, and most were unvaccinated, incompletely vaccinated, or had been vaccinated more than 5 years previously. Bordetella holmesii DNA was detected in 22% of the bordetellosis cases; these patients included adults; teenagers; and, surprisingly, young children. B. pertussis isolates were similar to the clinical isolates currently circulating elsewhere in Europe. One isolate does not express pertactin, an antigen included in some acellular pertussis vaccines.

    Latent class models are useful for classifying subjects by dietary patterns. Our goals were to use latent transition models to identify dietary patterns during pregnancy and postpartum, to estimate the prevalence of these dietary patterns, and to model transition probabilities between dietary patterns as a function of covariates. Women who were enrolled in the Pregnancy, Infection, and Nutrition Study (University of North Carolina, 2000-2005) were followed for 1 year postpartum, and their diets were assessed in the second trimester and at 3 and 12 months postpartum (n = 519, 484, and 374, respectively) by using a food frequency questionnaire. After adjusting for energy intake, parity, smoking status, race, and education, we identified 3 dietary patterns and named them "prudent," "health conscious Western," and "Western." Nulliparas were 2.9 and 2.1 times more likely to be in the "prudent" class than the "health conscious Western" or the "Western" class, respectively. The 3 dietary patterns were very stable, with the "health conscious Western" class being the least stable; the probability for staying in the same class was 0.74 and 0.87 at 3 and 12 months postpartum, respectively. Breastfeeding mothers were more likely than nonbreastfeeding mothers to switch dietary pattern class (P = 0.0286). Except for breastfeeding mothers, most women did not switch dietary patterns from pregnancy to postpartum.

    The 1-year dog toxicity study is no longer required by certain pesticide regulatory jurisdictions, including the United States and the European Union. Health Canada's Pest Management Regulatory Agency (PMRA) examined its current requirement for this study to determine if it could be refined or eliminated. A retrospective analysis was conducted to examine the impact of the 1-year dog study on human health risk assessment. The Acceptable Daily Intake (ADI), a measure of the amount of a pesticide in food that can be ingested on a daily basis over a lifetime without an appreciable health risk, was the metric for this analysis. For 143 pesticides evaluated by the PMRA between 2008 and 2015, the supporting toxicology databases were examined to determine if other toxicology studies were protective of the findings in the 1-year dog study. When this criterion was not met, further investigation was undertaken to determine the potential impact of not having the 1-year dog study. For most of the pesticides, effect levels in the 1-year dog study were not substantially different from those in other toxicology studies, when considering factors such as dose-spacing and known experimental variability. The results of this analysis suggest that absence of the 1-year dog study would have minimal impact on the assessment of human health risk. Therefore, Health Canada's PMRA has removed the routine requirement for the 1-year dog study from its pesticide data requirements.

    Objectives Several studies showed the close relationship between Rheumatoid Arthritis (RA) and cerebro-cardiovascular events (CVEs) and subclinical atherosclerosis. In this study, we investigated the occurrence of CVEs and subclinical atherosclerosis during the course of RA and we evaluated the possible role of both traditional cardiovascular (CV) and disease related risk factors to predict the occurrence of new CVEs and the onset of subclinical atherosclerosis. Methods We designed a single centre, bias-adjusted, prospective, observational study to investigate, in a homogeneous subset of RA patients, the occurrence of new onset of CVEs and subclinical atherosclerosis. Statistical analyses were performed to evaluate the role of traditional CV and disease-related risk factors to predict the occurrence of new CVEs and subclinical atherosclerosis. Results We enrolled 347 RA patients prospectively followed for 12 months. An increased percentage of patients experienced CVEs, developed subclinical atherosclerosis and was affected by systemic arterial hypertension (SAH), type 2 diabetes mellitus and metabolic syndrome (MS), at the end of follow up. Our analysis showed that the insurgence of both SAH and MS, during the follow up, the older age, the CVE familiarity and the lack of clinical response, were associated with a significantly increased risk to experience CVEs and to develop subclinical atherosclerosis. Conclusions Our study quantifies the increased expected risk for CVEs in a cohort of RA patients prospectively followed for 1 year. The occurrence of both new CVEs and subclinical atherosclerosis in RA patients may be explained by inflammatory burden as well as traditional CV risk factors. PMID:28103312

    Incidence and clinical manifestation of cow's milk protein intolerance (CMPI) were studied in 1158 unselected newborn infants followed prospectively from birth to 1 year of age. No food changes were required in 914 infants who were used as healthy controls. When CMPI was suspected (211 infants), diagnostic dietary interventions according to a standard protocol were performed. After exclusion of lactose intolerance, two positive cow's milk elimination/challenge tests were considered diagnostic of CMPI. Two hundred and eleven symptomatic infants were examined for possible CMPI. A large group of 80 infants improved on a lactose reduced formula. In 87/211 infants CMPI was excluded (sick controls). Finally CMPI was proven in 26 infants. The calculated incidence rate for CMPI was 2.8%. The principal symptoms in infants with CMPI were gastrointestinal, dermatological and respiratory in 50%, 31% and 19% respectively. A positive family history for atopy (first or second degree relatives) was more frequent in either CMPI infants (65%), or sick controls (63%) when compared to either healthy controls (35%) or infants improving on a low lactose formula (51%). Differences between patients with CMPI and sick controls were only found for the presence of atopy in at least 2 first degree relatives [(5/26 in CMPI infants and 4/87 in sick controls (P < 0.05)] and for multiorgan involvement [10/26 infants with CMPI as opposed to 12/87 in the sick control group (P < 0.02)]. These statistical differences are too weak to be of clinical value.

    We performed a multicenter prospective observational cohort study (Epidémiologie et Pronostic de l'Insuffisance Cardiaque Aiguë en Lorraine, Epidemiology and Prognosis of Acute Heart Failure in Lorraine [EPICAL2]) to evaluate the effectiveness on mortality of a community-based multidisciplinary disease management programme (DMP) for heart failure (HF) patients.Between October 2011 and October 2012, 1816 patients, who were hospitalized for acute HF or who developed acute HF during a hospitalization, were included from 21 hospitals in a northeast region of France. At hospital admission, their mean age was 77.3 (standard deviation [SD] 11.6) years and mean left ventricular ejection fraction was 45.0 (SD 16.0)%. A subset of patients were enrolled in a multidimensional DMP for HF (n = 312, 17.2%), based on structured patient education, home monitoring visits by HF-trained nurses, and automatic alerts triggered by significant clinical and biological changes to the patient. The DMP involved general practitioners, nurses, and cardiologists collaborating via an individual web-based medical electronic record. The outcome was all-cause mortality from the 3rd to the 12th month after discharge. During the follow-up, a total of 377 (20.8%) patients died: 321 (21.3%) in the control group and 56 (17.9%) in the DMP group. In a propensity score analysis, DMP was associated with lower 1-year all-cause mortality (hazard ratio 0.65, 95% CI 0.46-0.92). Instrumental variable analysis gave similar results (hazard ratio 0.56, 0.27-1.16).In a real world setting, a multidimensional DMP for HF with structured patient education, home nurse monitoring, and appropriate physician alerts may improve survival when implemented after discharge from hospitalization due to worsening HF.

    Early childhood caries (ECC) risk factors are suspected to vary between regions with different caries prevalence. Identify ECC risk factors for 1-year-olds predicting dentin caries at 3 years of age in a region with low caries prevalence. Caries risk was assessed by dental hygienist or dental assistant in 779 one-year-olds. The oral mutans streptococci (MS) score was performed from a tooth surface or (in pre-dentate children) from oral mucosa. A parental questionnaire with questions regarding family factors (siblings with or without caries), general health, food habits (night meals, breastfeeding, other beverage than water), oral hygiene habits and emerged teeth were answered by parents of the 1-year-olds. Dentin caries was assessed when the children were 3-year-olds. Simple and multiple logistic regression analyses were used for identification of caries-associated factors. An increased caries risk was assessed in 4.4% of the 1-year-olds. Dentin caries was found in 2.6% of the 3-year-olds. Caries risk at 1 year was associated with caries at 3 years (OR = 6.5, p = .002). Multiple regression analysis found the variables Beverages other than water (OR = 7.1, p year-olds in a region with low caries experience.

    To investigate the NMR relaxation times for irradiated rat lung tissue, we measured T1 and T2 at 11 different times during the injury's 1-year time course. A biexponential analysis of T2 was used to determine T2 fast (T2f) and T2 slow (T2s). In addition, we measured water content and correlated changes in the relaxation times with pathological changes. The correlation indicates the following: (1) Shortly after irradiation, the biexponential T2 decay for 1/3 of the samples became monoexponential and there were no noticeable pathological changes observed using light microscopy. (2) During radiation pneumonitis, T2f and T2s were prolonged. This accompanied acute edematous changes and inflammatory cell infiltration. (3) Finally, during radiation fibrosis T1 shortened and collagen increased. We observed no significant correlation between relaxation time changes and water content changes throughout the 1-year time course.

    One-year mortality is vital for elderly oncologic patients undergoing surgery. Recent studies have demonstrated that sarcopenia can predict outcomes after major abdominal surgeries, but the association of sarcopenia and 1-year mortality has never been investigated in a prospective study. We conducted a prospective study of elderly patients (≥65 years) who underwent curative gastrectomy for gastric cancer from July 2014 to July 2015. Sarcopenia was determined by the measurements of muscle mass, handgrip strength, and gait speed. Univariate and multivariate analyses were used to identify the risk factors associated with 1-year mortality. A total of 173 patients were included, in which 52 (30.1 %) patients were identified as having sarcopenia. Twenty-four (13.9 %) patients died within 1 year of surgery. Multivariate analysis showed that sarcopenia was an independent risk factor for 1-year mortality. Area under the receiver operating characteristic curve demonstrated an increased predictive power for 1-year mortality with the inclusion of sarcopenia, from 0.835 to 0.868. Solely low muscle mass was not predictive of 1-year mortality in the multivariate analysis. Sarcopenia is predictive of 1-year mortality in elderly patients undergoing gastric cancer surgery. The measurement of muscle function is important for sarcopenia as a preoperative assessment tool.

    While the role of childhood adversity in increasing the risk of psychosis has been extensively investigated, it is not clear what the impact of early adverse experiences is on the outcomes of psychotic disorders. Therefore, we investigated associations between childhood adversity and 1-year outcomes in 285 first-presentation psychosis patients. Exposure to childhood adversity prior to 17 years of age was assessed using the Childhood Experience of Care and Abuse Questionnaire. Data on illness course, symptom remission, length of psychiatric hospitalization, compliance with medication, employment, and relationship status were extracted from clinical records for the year following first contact with mental health services for psychosis. Seventy-one percent of patients reported exposure to at least 1 type of childhood adversity (physical abuse, sexual abuse, parental separation, parental death, disrupted family arrangements, or being taken into care). No robust associations were found between childhood adversity and illness course or remission. However, childhood physical abuse was associated with almost 3-fold increased odds of not being in a relationship at 1-year follow-up compared to patients who did not report such adverse experiences. There was also evidence of a significant association between parental separation in childhood and longer admissions to psychiatric wards during 1-year follow-up and 2-fold increased odds of noncompliance with medication compared to those not separated from their parents. Therefore, our findings suggest that there may be some specificity in the impact of childhood adversity on service use and social functioning among psychosis patients over the first year following presentation to mental health services.

    The objectives of the current study were to determine the prevalence of food addiction in bariatric surgery candidates and whether food addiction is associated with weight loss after bariatric surgery. This prospective observational study was performed on morbidly obese patients who had been found suitable for bariatric surgery. Follow-up was conducted at the 6 and 12 month post-surgery. The Yale Food Addiction Scale (YFAS) was used to determine food addiction. One hundred seventy-eight patients were included. Pre-operative food addiction was found in 57.8% of patients. Food addiction prevalence decreased at the 6 and 12 month follow ups, to 7.2% and 13.7% respectively. There were no statistically differences between those with food addiction and those without addiction with regard to weight loss measured as percent of excess BMI at the 12 month follow-up. Food addiction as measured by the YFAS decreases significantly after bariatric surgery. The presence of food addiction before surgery was not associated with weight loss as measured EBL%. However, in view of the increase in BMI, 2 years after surgery longer follow up studies are warranted. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

    Schmitt, Zachary L; Livingston, Michael G

    2015-01-01

    This study explored the pattern of video game usage and video game addiction among male college students and examined how video game addiction was related to expectations of college engagement, college grade point average (GPA), and on-campus drug and alcohol violations. Participants were 477 male, first year students at a liberal arts college. In the week before the start of classes, participants were given two surveys: one of expected college engagement, and the second of video game usage, including a measure of video game addiction. Results suggested that video game addiction is (a) negatively correlated with expected college engagement, (b) negatively correlated with college GPA, even when controlling for high school GPA, and (c) negatively correlated with drug and alcohol violations that occurred during the first year in college. Results are discussed in terms of implications for male students' engagement and success in college, and in terms of the construct validity of video game addiction.

    Insulin pump failure and/or malfunction requiring replacement have not been thoroughly investigated. This study evaluated pump replacement in children and adolescents with Type 1 diabetes using insulin pump therapy. Data were collected for all participants younger than 19 years, starting insulin pump therapy before 31 December 2013. For each child, age, disease duration, date of insulin pump therapy initiation, insulin pump model, failure/malfunction/replacement yes/no and reason were considered for the year 2013. Data were returned by 40 of 43 paediatric centres belonging to the Diabetes Study Group of the Italian Society of Paediatric Endocrinology and Diabetology. In total, 1574 of 11 311 (13.9%) children and adolescents with Type 1 diabetes were using an insulin pump: 29.2% Animas VIBE(™) , 9.4% Medtronic MiniMed 715/515(™) , 34.3% Medtronic MiniMed VEO(™) , 24.3% Accu-Check Spirit Combo(™) and 2.8% other models. In 2013, 0.165 insulin pump replacements per patient-year (11.8% due to pump failure/malfunction and 4.7% due to accidental damage) were recorded. Animas VIBE(™) (22.1%) and Medtronic MiniMed VEO(™) (17.7%) were the most replaced. In a large cohort of Italian children and adolescents with Type 1 diabetes, insulin pump failure/malfunction and consequent replacement are aligned with rates previously reported and higher in more sophisticated pump models. © 2016 Diabetes UK.

    OBJECTIVE The purpose of this study was to investigate white matter (WM) structural abnormalities using diffusion tensor imaging (DTI) in children with hydrocephalus before CSF diversionary surgery (including ventriculoperitoneal shunt insertion and endoscopic third ventriculostomy) and during the course of recovery after surgery in association with neuropsychological and behavioral outcome. METHODS This prospective study included 54 pediatric patients with congenital hydrocephalus (21 female, 33 male; age range 0.03-194.5 months) who underwent surgery and 64 normal controls (30 female, 34 male; age range 0.30-197.75 months). DTI and neurodevelopmental outcome data were collected once in the control group and 3 times (preoperatively and at 3 and 12 months postoperatively) in the patients with hydrocephalus. DTI measures, including fractional anisotropy (FA), mean diffusivity (MD), axial diffusivity (AD), and radial diffusivity (RD) values were extracted from the genu of the corpus callosum (gCC) and the posterior limb of internal capsule (PLIC). Group analysis was performed first cross-sectionally to quantify DTI abnormalities at 3 time points by comparing the data obtained in the hydrocephalus group for each of the 3 time points to data obtained in the controls. Longitudinal comparisons were conducted pairwise between different time points in patients whose data were acquired at multiple time points. Neurodevelopmental data were collected and analyzed using the Adaptive Behavior Assessment System, Second Edition, and the Bayley Scales of Infant Development, Third Edition. Correlation analyses were performed between DTI and behavioral measures. RESULTS Significant DTI abnormalities were found in the hydrocephalus patients in both the gCC (lower FA and higher MD, AD, and RD) and the PLIC (higher FA, lower AD and RD) before surgery. The DTI measures in the gCC remained mostly abnormal at 3 and 12 months after surgery. The DTI abnormalities in the PLIC were

    Attempts to predict who is at risk of future nonadherence have largely focused on predictions at the time of therapy initiation; however, these users are only a small proportion of all patients on therapy at any point in time. Methods to predict nonadherence for established medication users, which have not been previously described in the literature, would be helpful to guide efforts to enhance the use of evidence-based therapies. To test approaches for adherence prediction among prevalent statin users, namely the use of short-term filling behavior, investigator-specified predictors from medical and pharmacy administrative claims, and the empirical selection of potential predictors using the high-dimensional propensity score variable selection algorithm. Medical and prescription claims data from a large national health insurer were used to create a cohort of patients who filled statin medication prescriptions in January 2012. We defined 6 groups of adherence predictors and estimated 10 main models to predict medication adherence in the full cohort. The same was done for the population stratified based on the days supply of the index statin prescription (≤ 30 days vs. > 30 days). The study cohort consisted of 93,777 individuals, 58.4% of which were adherent to statins during follow-up. The use of 3 pre-index adherence predictors alone achieved a c-statistic of 0.70. Investigator-specified and empirically selected pharmacy, medical, and demographic variables did substantially worse (0.57-0.60). The use of 3 indicators of post-index adherence achieved a higher c-statistic than the best-performing model using pre-index information (0.74 vs. 0.72). The addition of 3 pre-index adherence predictors further improved discrimination (0.78). This analysis demonstrated the ability to predict adherence among medication users using filling behavior before and immediately after an index prescription fill.

    Object To investigate white matter structural abnormalities using diffusion tensor imaging (DTI) in children with hydrocephalus before CSF diversionary surgery (including ventriculoperitoneal shunting and endoscopic third ventriculoscopy) and the course of recovery post-surgery in association with neuropsychological and behavioral outcome. Methods This was a prospective study that included 54 children with congenital hydrocephalus (21F/33M; age range: 0.03–194.5 months) who underwent surgery and 64 normal controls (30F/34M, age range: 0.30–197.75 months). DTI and neurodevelopmental outcome data were collected once in the control group and at pre-surgery, 3-month, and 12-month post-surgery in the patients. DTI measures, including fractional anisotropy (FA), mean diffusivity (MD), axial diffusivity (AD), and radial diffusivity (RD) values were extracted from the genu of corpus callosum (gCC) and the posterior limb of internal capsule (PLIC). Group analysis was performed first cross-sectionally to quantify DTI abnormalities at three time points by comparing the controls and the patients group at the three time points separately. Longitudinal comparisons were conducted pairwise between different time points in patients whose data were acquired at multiple time points. Neurodevelopmental data were collected and analyzed using the Adaptive Behavior Assessment System, Second Edition (ABAS-II) and the Bayley Scales of Infant Development, Third Edition (Bayley-III). Correlation analyses were performed between DTI and behavioral outcomes. Results Significant DTI abnormalities were found in both the gCC (lower FA and higher MD, AD, and RD) and the PLIC (higher FA, lower AD and RD) at pre-surgery. The DTI measures in the gCC remained mostly abnormal at 3-month and 12-month post-surgery. The DTI abnormalities in the PLIC were significant in FA and AD at 3-month post-surgery but did nor persist when tested at 12-month post-surgery. Significant longitudinal DTI changes in the

    Antipsychotic adjunctive therapy to mood stabilizers (MSs) may improve relapse prevention; however, only a few naturalistic studies, reflecting more generalizable bipolar disorder (BD) samples, support this notion. We compared the 1-year rehospitalization rates of manic patients with bipolar I disorder (BD-I) who were discharged with MS (lithium or valproate) monotherapy or with adjunctive atypical or typical antipsychotic therapy. A total of 201 patients with BD-I who were hospitalized with manic episodes between 2005 and 2013 were retrospectively followed for 1-year rehospitalization rates according to treatment at discharge: MS monotherapy, MS with atypical antipsychotics, and MS with typical antipsychotics. Additionally, time to rehospitalization during the 1-year period after discharge was compared between treatment groups. Multivariable survival analyses adjusted for covariates known to influence rehospitalization were conducted. Rehospitalization rates within 1 year were significantly lower in the MS with atypical antipsychotics group (6.3%) compared to the MS monotherapy group (24.3%, P=.008) and to the MS with typical antipsychotics group (20.6%, P=.02). Time to rehospitalization was significantly longer for the MS with atypical antipsychotics group (345.5 days) compared to the MS monotherapy group (315.1 days, P=.006) and to the MS with typical antipsychotics group (334.1 days, P=.02). The MS with atypical antipsychotics group had a significantly reduced adjusted risk of rehospitalization (hazard ratio=0.17, 95% confidence interval: 0.05-0.61, P=.007) compared to the MS monotherapy group. Atypical antipsychotic adjunctive therapy to MSs may be more effective than MS monotherapy in preventing rehospitalization during the 1-year period after a BD manic episode. © 2016 John Wiley & Sons A/S.

However, although many studies have investigated event-related potentials (ERPs in patients with OCD compared with healthy control subjects, it is currently unknown whether ERP changes reflect pharmacological and psychotherapeutic effects. As such, the current study examined the neurocognitive components of OCD to elucidate the pathophysiological abnormalities involved in the disorder, including the frontal-subcortical circuits.Methods: The Yale-Brown Obsessive-Compulsive Scale was used to evaluate 14 adult patients with OCD. The present study also included ten age-, sex-, and IQ-matched controls. The P300 and mismatch negativity (MMN components during an auditory oddball task at baseline for both groups and after 1 year of treatment for patients with OCD were measured.Results: Compared with controls, P300 amplitude was attenuated in the OCD group at Cz and C4 at baseline. Pharmacotherapy and psychotherapy treatment for 1 year reduced OCD symptomology. P300 amplitude after 1 year of treatment was significantly increased, indicating normalization compared with baseline at Fz, Cz, C3, and C4. We found no differences in P300 latency, MMN amplitude, or MMN latency between baseline and after one year of treatment.Conclusion: ERPs may be a useful tool for evaluating pharmacological and cognitive behavioral therapy in adult patients with OCD.

    Full Text Available Abstract Background Gait variables derived from trunk accelerometry may predict the risk of falls; however, their associations with falls are not fully understood. The purpose of the study was to determine which gait variables derived from upper and lower trunk accelerometry are associated with the incidence of falls, and to compare the discriminative ability of gait variables and physical performance. Methods This study was a 1-year prospective study. Older people (n = 73 walked normally while wearing accelerometers attached to the upper and lower trunk. Participants were classified as fallers (n = 16 or non-fallers (n = 57 based on the incidence of falls over 1 year. The harmonic ratio (HR of the upper and lower trunk was measured. Physical performance was measured in five chair stands and in the timed up and go test. Results The HR of the upper and lower trunk were consistently lower in fallers than non-fallers (P P Conclusions HR derived from upper trunk accelerometry may predict the risk of falls, independently of physical performance. The discriminative ability of HR for the risk of falls may have some validity, and further studies are needed to confirm the clinical relevance of trunk HR.

    Neck pain is more prevalent in office workers than in the general community. To date, findings from prospective studies that investigated causal relationships between putative risk factors and the onset of neck pain in this population have been limited by high loss to follow-up. The aim of this research was to prospectively evaluate a range of risk factors for neck pain in office workers, using validated and reliable objective measures as well as attain an estimate of 1-year incidence. We assembled a cohort of 53 office workers without neck pain and measured individual, physical, workplace and psychological factors at baseline. We followed participants for 1 year to measure the incidence of neck pain. We achieved 100% participant follow-up. Cox regression analysis was applied to examine the relationship between the putative risk factors and the cumulative incidence of neck pain. The 1-year incidence proportion of neck pain in Australian office workers was estimated in this study to be 0.49 (95% CI 0.36-0.62). Predictors of neck pain with moderate to large effect sizes were female gender (HR: 3.07; 95% CI: 1.18-7.99) and high psychological stress (HR: 1.64; 95% CI: 0.66-4.07). Protective factors included increased mobility of the cervical spine (HR: 0.44; 95% CI: 0.19-1.05) and frequent exercise (HR: 0.64; 95% CI: 0.27-1.51). These results reveal that neck pain is common in Australian office workers and that there are risk factors that are potentially modifiable.

    Eighty patients, of whom 22 were men and 58 women, participated in a 1-year follow-up study. All participants in the study showed signs and symptoms of craniomandibular disorders (CMD) and had had pain for more than 6 months at treatment start. The patients were randomly assigned to either acupuncture or occlusal splint therapy. Those patients who did not respond to either of the treatment modes were offered various additional therapies. The result showed that 57% of the patients who received acupuncture and 68% of the patients treated with occlusal splint therapy benefited subjectively (p < 0.01) and clinically (p < 0.001) from the treatment over a 12-month period. No statistically significant difference was found between the two groups as to the assessment variables. Those patients who received various additional therapies after acupuncture and/or occlusal splint therapy responded favorably to additional treatment in only a few instances. The study showed that acupuncture gave positive results similar to those of occlusal splint therapy in patients with primarily myogenic CMD symptoms over a 1-year follow-up period.

    To evaluate the prevalence and predictors of anal incontinence (AI) in late pregnancy and 1 year after delivery. Prospective population-based cohort study. Two maternity units in Norway 2009-2010. Primiparae aged 18 years or over. Primiparae answered questions on the St. Mark's score about AI during the last 4 weeks of pregnancy. One year later, the same questionnaires were distributed by postal mail. Socio-economic and delivery-related data were obtained from hospital records. Self-reported AI. Answers on AI in late pregnancy were obtained from 1571 women, and 1030 responded 1 year later. Twenty-four per cent experienced one and 4.7% experienced three or more AI symptoms in late pregnancy. One year later, this was reduced to 19% and 2.2%, respectively. Multivariate logistic regression analyses were applied. Formed and loose stool incontinence were strongly associated at both time points. The main predictor of AI 1 year after delivery was AI in late pregnancy. Obstetric anal sphincter injury increased the risk of incontinence of stool and flatus (odds ratio [OR], 4.1; 95% confidence interval [CI], 1.7-9.6) after delivery. Urgency was associated with greater age (OR, 1.8; 95% CI, 1.0-3.3) and operative delivery (OR, 2.0; 95% CI, 1.3-2.9). One in four primiparae experienced AI in late pregnancy. One year later, still one in five suffered from incontinence. Sphincter injury predicted incontinence of stool and flatus, whereas greater age and operative delivery predicted urgency. The identification and adequate follow-up of pregnant women with AI may reduce AI after delivery. © 2013 Royal College of Obstetricians and Gynaecologists.

    Malnutrition is a serious health concern for frail elderly people. Poor oral function leading to insufficient food intake can contribute to the development of malnutrition. In the present study, we explored the longitudinal association of malnutrition with oral function, including oral health status and swallowing function, in elderly people receiving home nursing care. Prospective observational cohort study with 1-year follow-up. Two mid-sized cities in Fukuoka, Japan from November 2010 to March 2012. One hundred and ninety-seven individuals, aged ≥ 60 years, living at home and receiving home-care services because of physical disabilities, without malnutrition. Oral health status, swallowing function, taking modified-texture diets such as minced or pureed foods, nutritional status, cognitive function, and activities of daily living were assessed at baseline. The associations between malnutrition at 1-year follow-up and these related factors were analyzed using a logistic regression model. Swallowing disorders [risk ratio (RR): 5.21, 95% confidence interval (95% CI): 1.65-16.43] were associated with malnutrition. On the other hand, oral health status did not have a direct association with malnutrition. Swallowing disorders may be associated with the incidence of malnutrition in elderly people receiving home-care. The findings indicate that maintaining swallowing function may contribute to the prevention of malnutrition in frail elderly people.

    Studies comparing alternatives to ventriculoperitoneal (VP) shunting for treatment of hydrocephalus have often relied upon data from an earlier era that may not be representative of contemporary shunt survival outcomes. We sought to determine the shunt survival rate of our cohort and compare our results to previously published shunt survival and endoscopic third ventriculostomy (ETV) success rates. We identified 95 patients between 1 and 18 years of age, who underwent initial VP shunt placement between January 2001 and December 2010. Our study shows a shunt survival rate of 85% at 6 months and 79% at 2 years, for initial shunts in pediatric patients over 1 year of age in this cohort. The overall infection rate was 3%. This compares favorably with published success rates of ETV at similar time points as well as with the rate of infection. This suggests that ventricular shunting remains a viable alternative to ETV in the older child.

    The purpose of this 1-year prospective study was to determine whether sarcopenia is an independent risk factor of cognitive deterioration in community-dwelling older adults. One-year prospective study. Japanese community. A total of 131 community-dwelling older adults aged 65 years and older participated in this study. We defined sarcopenia using the diagnostic algorithm recommended by the Asian Working Group for Sarcopenia, and the participants were classified into the sarcopenia and normal groups according to this definition. The participants' cognitive functions were assessed using the Mini-Mental State Examination (MMSE) during pre- and postdata collection (after 1 year). The rate of change in pre- and post-MMSE scores during the follow-up term was significantly different between the 2 groups (normal group, -0.32 ± 8.39%; sarcopenia group, -5.86 ± 5.16%; P = .002). The analysis of covariance, adjusted for demographic data and the pre-MMSE scores, showed a significant change in the MMSE scores between the normal and sarcopenia group (F = 9.30, P = .003). Furthermore, in the multivariate logistic regression analysis, the cognitive function was significantly more likely to deteriorate (defined as a loss of at least 2 points of MMSE) in the sarcopenia group during the follow-up term (odds ratio: 7.86, 95% confidence interval: 1.53-40.5). Sarcopenia was identified as an independent risk factor of cognitive deterioration in community-dwelling older adults during the 1-year study period.

    In the last decade, tonsillotomy has come into vogue again, whereas the number of tonsillectomies is decreasing rapidly. In a previous study, the tonsillotomy with laser or radiofrequency therapy proved as a safe and effective procedure with minimal pain and hemorrhage. This follow-up study determines which method is more effective with respect to long-term outcome, recurrence of tonsillar hyperplasia and recurrence of tonsillitis. A prospective, randomised, double-blinded controlled clinical study was conducted at the Department of Otorhinolaryngology of the Ludwig-Maximilians-University, Munich, Germany. Twenty-six children with tonsillar hypertrophy were included. Tonsillotomy was performed on one side with monopolar radiofrequency and on the other side with a carbon dioxide laser. Exactly 1 year after the procedure, all 26 patients were documented by digital photography to define a possible recurrence of tonsillar hyperplasia. All parents were asked for occurring tonsillitis and fulfilled the Glasgow Children's Benefit Inventory (GCBI) for health-related quality of life after surgical procedures. In seven children, a slightly visible recurrence of the tonsillar hyperplasia occurred, without any symptoms or correlation to the different methods and sides. One child with recurrent tonsillitis and hyperplasia had to be tonsillectomized 8 months after the initial tonsillotomy procedure. The specimen showed open crypts with bacterial infection in the deep. The GCBI resulted in highly significant benefits of the surgery in all categories and subcategories. In conclusion, both methods, the laser tonsillotomy and the radiofrequency method, were equal concerning the effectiveness and safety after 1 year. Further investigations have to aim at the long-term outcome after tonsillotomy in patients with recurrent infections.

    This study evaluated by standardised digitised periapical radiography the crestal bone maintenance around modified diameter internal hex implants with variable thread design and narrow neck loaded with different procedures. Forty implants were placed in 25 patients. Twenty implants were conventionally loaded, 20 ones immediately loaded. Radiographs were taken with a customised bite record and processed with software. Measurements of bone from the fixture-abutment junction to mesial and distal marginal bone levels were made. Student's t test statistical analysis was adopted. Baseline data were variable; at 1-year follow-up, there were no significant differences for marginal bone loss between immediately and conventionally loaded maxillary implants (p = 0.1031), whilst there were slight significant differences between immediately and conventionally loaded implants in the mandible (p = 0.0141). Crestal bone maintenance around conventionally and immediately loaded modified diameter implants was similar, with slight significant differences in mandible where a lower marginal bone loss was observed.

    We have previously reported that the public employees of Watari town showed significantly greater elevations in both systolic and diastolic blood pressure than the general population 4-8 months after the Great East Japan Earthquake, which occurred on 11 March 2011. To examine whether these differences persisted thereafter, we conducted a follow-up study for both the public employees and the general population of Watari town over 1 year. Among 225 public employees and 1232 individuals from the general population of the town who received consecutive annual health checkups from 2010 to 2012, 89 pairs were matched for age and sex according to a propensity score. The baseline characteristics (predisaster) did not statistically differ between the paired groups. The public employees showed significantly higher systolic and diastolic blood pressure in 2011 (postdisaster) compared with the general population (129.8 ± 14.0/78.0 ± 11.7 vs. 117.0 ± 14.4/71.6 ± 11.4 mm Hg, P < 0.001 for both). Furthermore, the systolic blood pressure of the public employees remained significantly higher than that of the general population in 2012 (125.3 ± 16.0 vs. 119.9 ± 15.5 mm Hg, P = 0.023). Prolonged blood pressure elevation among the public employees was observed for more than 1 year after the disaster, suggesting a need for close blood pressure monitoring of public employees engaged in long-term disaster relief operations. © American Journal of Hypertension, Ltd 2016.

    The aim of this study was to determine whether soccer could have different bone benefits in prepubescent and pubescent boys. We investigated 76 boys aged 10 to 13 years during a 1-year study. All boys were prepubescent at the beginning of the study (T0); pubescent status was determined by a complete 24-h urine hormonal assay of FSH-LH, with LH ≤ 0.31 IU/24 h and FSH ≤ 2.19 IU/24 h corresponding to prepubescent Tanner stage I and with 0.31 soccer players (F1) and 13 controls (C1)), and 41 boys had entered puberty (26 soccer players (F2) and 15 controls (C2)). Soccer players completed 2 to 5 h of training plus one competition game per week during the school year, and controls only had physical education at school. Bone mineral content (BMC) was measured at T0 and T1 by DPX in the lumbar spine, total hip, and whole body (WB) for a comparison between soccer players and controls. At T0, no BMC difference was found between F1 and C1, but BMC was higher in F2 than C2 in WB and weight-bearing sites. At T1, BMC was higher in WB and weight-bearing sites in both F1 and F2 compared to their respective controls. Between T0 and T1, soccer induced a BMC gain at weight-bearing sites in both F1 and F2 compared to C1 and C2, respectively. The soccer-related bone gain was greater in WB and weight-bearing (the lumbar spine, total hip, and supporting leg) and non-weight-bearing bones (dominant arm and nondominant arm) in boys who became pubescent than in boys who remained prepubescent. In conclusion, 1-year study in young male soccer players demonstrates that the process of bone accretion at the very early phase of puberty is more intensely stimulated by the combination of physical exercise and sexual impregnation than by one of these factors alone.

    Contamination of hot water distribution systems by Legionella represents a great challenge due to difficulties associated with inactivating microorganisms, preserving the water characteristics. The aim of this study was to examine over the course of 1 year in 11 fixed sites, the impact of monochloramine disinfection on Legionella, heterotrophic bacteria (36 °C), Pseudomonas aeruginosa contamination, and chemical parameters of a plumbing system in an Italian hospital. Three days after installation (T0), in the presence of monochloramine concentration between 1.5 and 2 mg/L, 10/11 sites (91%) were contaminated by L. pneumophila serogroups 3 and 10. After these results, the disinfectant dosage was increased to between 6 and 10 mg/L, reducing the level of Legionella by three logarithmic unit by 2 months postinstallation (T2) until 6 months later (T3). One year later (T4), there was a significant reduction (p = 0.0002) at 8/11 (73%) sites. Our data showed also a significant reduction of heterotrophic bacteria (36 °C) in 6/11 (55%) sites at T4 (p = 0.0004), by contrast the contamination of P. aeruginosa found at T0 in two sites persisted up until T4. The results of the present study show that monochloramine is a promising disinfectant that can prevent Legionella contamination of hospital water supplies.

    Full Text Available This study aims to identify the predictors in the different aspects of the health-related quality of life (HRQoL and to measure the changes of functional status over time in a cohort of Nigerian stroke survivors. A prospective observational study was conducted in three hospitals of Kano state of Nigeria where stroke survivors receive rehabilitation. The linguistic-validated Hausa versions of the stroke impact scale 3.0, modified Rankin scale, Barthel index and Beck depression inventory scales were used. Paired samples t-test was used to calculate the amount of changes that occur over time and the forward stepwise linear regression model was used to identify the predictors. A total of 233 stroke survivors were surveyed at 6 months, and 93% (217/233 were followed at 1 year after stroke. Functional disabilities were significantly reduced during the recovery phase. Motor impairment, disability, and level of depression were independent predictors of HRQoL in the multivariate regression analysis. The involvement of family members as caregivers is the key factor for those survivors with improved functional status. Thus, to enhance the quality of poststroke life, it is proposed that a holistic stroke rehabilitation service and an active involvement of family members are established at every possible level.

    Efficacy and safety of iron chelation therapy with deferasirox in iron-overloaded non-transfusion-dependent thalassaemia (NTDT) patients were established in the THALASSA study. THETIS, an open-label, single-arm, multicentre, Phase IV study, added to this evidence by investigating earlier dose escalation by baseline liver iron concentration (LIC) (week 4: escalation according to baseline LIC; week 24: adjustment according to LIC response, maximum 30mg/kg/day). The primary efficacy endpoint was absolute change in LIC from baseline to week 52. 134 iron-overloaded non-transfusion-dependent anaemia patients were enrolled and received deferasirox starting at 10mg/kg/day. Mean actual dose±SD over 1year was 14.70±5.48mg/kg/day. At week 52, mean LIC±SD decreased significantly from 15.13±10.72mg Fe/g dw at baseline to 8.46±6.25mg Fe/g dw (absolute change from baseline, -6.68±7.02mg Fe/g dw [95% CI: -7.91, -5.45]; P<0.0001). Most common drug-related adverse events were gastrointestinal: abdominal discomfort, diarrhoea and nausea (n=6 each). There was one death (pneumonia, not considered drug related). With significant and clinically relevant reductions in iron burden alongside a safety profile similar to that in THALASSA, these data support earlier escalation with higher deferasirox doses in iron-overloaded non-transfusion-dependent anaemia patients.

This study identified characteristics that differentiate patients with schizophrenia who are treated with olanzapine monotherapy versus polypharmacy in usual care in Japan.Patients and methods: In a large (N = 1850 prospective, observational study, Japanese patients with schizophrenia who initiated treatment with olanzapine were followed for 1 year. Consistent with past research, antipsychotic polypharmacy was defined as the concurrent use of olanzapine and another antipsychotic for at least 60 days. Switching was defined as discontinuing a prior antipsychotic therapy rather than augmenting the medication regimen. Predictors of antipsychotic monotherapy were based on information available at the time of olanzapine initiation. Baseline characteristics were compared using t-tests and Χ2 tests. Stepwise logistic regression was used to identify independent predictors of monotherapy.Results: Patients treated with olanzapine monotherapy (43.2% differed from those treated with antipsychotic polypharmacy (56.8% on demographics, treatment history, baseline symptom levels, functional levels, and treatment-emergent adverse events. Stepwise logistic regression identified multiple variables that significantly predicted monotherapy: older age, shorter duration of schizophrenia, outpatient status, comorbid medical conditions, lower body mass index, no prior anticholinergic use, no prior mood stabilizer use, and switching from a previous antipsychotic (typical or atypical

    Objective Singing group participation may benefit patients with chronic obstructive pulmonary disease (COPD). Previous studies are limited by small numbers of participants and short duration of generally hospital-based singing group intervention. This study examines the feasibility of long-term participation in a community singing group for patients with COPD who had completed pulmonary rehabilitation (PR). Methods This was a feasibility cohort study. Patients with COPD who had completed PR and were enrolled in a weekly community exercise group were recruited to a new community-based singing group which met weekly for over 1 year. Measurements at baseline, 4 months and 1 year comprised comprehensive pulmonary function tests including lung volumes, 6 min walk test (6MWT), Clinical COPD Questionnaire (CCQ), Hospital Anxiety and Depression Scale (HADS) and hospital admission days for acute exacerbation of COPD (AECOPD) for 1 year before and after the first singing group session. Findings There were 28 participants with chronic lung disease recruited from 140 people approached. Five withdrew in the first month. 21 participants meeting Global Initiative for Chronic Obstructive Lung Disease criteria for COPD completed 4-month and 18 completed 1-year assessments. The mean attendance was 85%. For the prespecified primary outcome measure, total HADS score, difference between baseline and 12 months was −0.9, 95% CI −3.0 to 1.2, p=0.37. Of the secondary measures, a significant reduction was observed for HADS anxiety score after 1 year of −0.9 (95% CI −1.8 to −0.1) points, p=0.038 and an increase in the 6MWT at 1 year, of 65 (95% CI 35 to 99) m compared with baseline psinging group for adults with COPD who have completed PR and are enrolled in a weekly community exercise group and provide evidence of improved exercise capacity and a reduction in anxiety.

    Extension strategy-tactics-planning (ESTP), based upon the science of Extenics, is established for the purpose of solving contradictory problems. In this paper, the fundamental thoughts, theories and methods of ESTP are introduced concisely. The highlights of ESTP are that the techniques, used in the case of tackling such problems as how to generate the ideas of strategy-tactics-planning, how to completely analyze the resources, how to exploit extension resources, how to transfer the incompatible into the compati-ble, and how to transfer the opposite into the co-existent, are developed in a formalized way. And regarding the practices of ESTP, the applications of ESTP in resource integration, project, market development, and the prevention and handling crises are presented.

    A timely return to competitive sport is a primary goal of anterior cruciate ligament reconstruction (ACLR). It is not known if an accelerated return-to-sport increases the risk of early-onset knee osteoarthritis (KOA). To determine whether an accelerated return-to-sport post-ACLR (i.e., return-to-sport and early KOA features stratified by type of ACL injury (isolated or concurrent chondral/meniscal injury) and lower-limb function (good or poor). Cross-sectional study SETTING: Private radiology clinic and university laboratory PARTICIPANTS: 111 participants (71 males; mean age 30±8 years) 1-year post-ACLR METHODS: Participants completed a self-report questionnaire regarding postoperative return-to-sport data (specific sport, postoperative month first returned), and isotropic 3T MRI scans were obtained. Early KOA features (bone marrow, cartilage and meniscal lesions, and osteophytes) assessed using the MRI OA Knee Score. Logistic regression analyses evaluated the odds of early KOA features with an accelerated return-to-sport (return-to-sport) in the total cohort, and stratified by type of ACL injury and lower-limb function. Forty-six (41%) participants returned to competitive sport return-to-sport was associated with significantly increased odds of bone marrow lesions (BMLs) (odds ratio [OR] 2.7, 95% confidence interval [CI] 1.3, 6.0) but not cartilage (OR 1.2, 95%CI 0.5, 2.6) or meniscal lesions (OR 0.8, 95%CI 0.4, 1.8), or osteophytes (OR 0.6, 95%CI 0.3, 1.4). In those with poor lower-limb function, early return-to-sport exacerbated the odds of BMLs (OR 4.6, 95%CI 1.6, 13.5), whereas stratified analyses for type of ACL injury did not reach statistical significance. An accelerated return-to-sport, particularly in the presence of poor lower-limb function may be implicated in post-traumatic KOA development.

    Over 400 active pesticides are registered in Japan (FAMIC 2013). The results of dog toxicity studies (usually, the 1-year study) were used by the Japanese regulatory authorities to establish the acceptable daily intake (ADI) for 45 pesticide active ingredients (about 9%). A retrospective review of ADIs established in Japan with dog studies as pivotal data for their derivation was performed: the ADIs were reassessed under the assumption that the 1-year dog study would not be available and an alternate ADI was derived based on the remaining toxicology database. In 35 of the 45 cases (77.8%) the ADI resulting from the absence of the 1-year dog study was no greater than twice the Japanese ADI, a difference considered not to be of biological significance. In 6 cases (13%) the resulting ADI was 2-5 times higher, which is considered of questionable biological relevance. On further evaluation of the database, three of these six cases were assessed as to clarify that there is no clear difference and for the other three additional studies to clarify that uncertain findings would have been required. In 3 of the 45 cases (7%) there may be a real difference within the ADI ratio of 2-5. Only in 1 case (2.2%) ADI was five times higher than that has been set. Accordingly, the absence of a 1-year dog study does not appear to influence the ADI derivation in a relevant manner in more than 98% of cases. For the four compounds with a real difference in ADI, consumer exposure would still be well below the alternative ADI. Therefore, a strong case can be made that the standard mandatory requirement to conduct a 1-year dog study, in addition to the 3-month study, is not justified and of no additional value in protecting human health. In addition, a substantial reduction in test animals could be achieved.

    To evaluate the safety and efficacy of the relatively selective M(1) antagonist pirenzepine hydrochloride in slowing the progression of myopia in school-aged children. This was a parallel-group, placebo-controlled, double-masked study in healthy children, aged 8 to 12 years, with a spherical equivalent of -0.75 to -4.00 diopters (D) and astigmatism of 1.00 D or less. Patients underwent a baseline complete eye examination and regular examinations during a 1-year period. The setting was 13 US academic clinics and private practices. Patients were randomized in a 2:1 ratio to receive 2% pirenzepine ophthalmic gel or a placebo control twice daily for 1 year. At study entry, the spherical equivalent was mean +/- SD -2.098 +/- 0.903 D for the pirenzepine group (n = 117) and -1.933 +/- 0.825 D for the placebo group (n = 57, P = .22). At 1 year, there was a mean increase in myopia of 0.26 D in the pirenzepine group vs 0.53 D in the placebo group (P pirenzepine group discontinued participation in the study because of adverse effects (5 [4%] of 117 due to excessive antimuscarinic effects). Pirenzepine is effective and relatively safe in slowing the progression of myopia during a 1-year treatment period.

    The introduction of digital planning programs has made it possible to place dental implants in preplanned positions and being immediately functionally loaded by using prefabricated prostheses. The aim of this multicenter study was to describe the 1-year results of digitally planned, immediately loaded edentulous maxillae. A total of 312 implants (Brånemark System, TiUnite RP, Nobel Biocare, Göteborg, Sweden) in 52 patients from eight Scandinavian clinics were digitally planned, surgically as well as prosthetically, by using the NobelGuide (Nobel Biocare AB, Göteborg, Sweden) and received prefabricated, immediately loaded fixed prosthetic constructions in the maxillae. Individual implant stability was manually tested at 1-year follow-up. All patients received a Procera Implant Bridge (Nobel Biocare AB); however, in two cases, the bridges were reconstructed due to misfit. In five patients, difficulties in getting the surgical guide completely in position, and in five patients, getting the prostheses completely seated, were noted. All but four patients fulfilled the 1-year follow-up. Two implants were lost during the study period, resulting in a cumulative survival rate of 99.4%. The mean marginal bone resorption from implant placement to the 1-year follow-up was 1.3 mm (SD 1.28). More than 2 mm of marginal resorption was noted in 19% of the implants at this instant. The most frequently reported complications during the first year were gingival hyperplasia and prosthesis-related problems (prosthesis screw loosening, occlusal fractures, and occlusal adjustments). The 1-year results in this multicenter are promising regarding implant and bridge stability; however, the study is planned to be running for at least 3 years.

    2017-05-01

    Full Text Available BACKGROUND Heart Failure (HF is a leading cause of hospitalisation and death across the globe. An idea about predictors of mortality can help physician in patient prognosis as well as decision making about the type and intensity of care of hospitalised patients. The aim of the present study is to identify clinical factors that predict mortality at one year post discharge in HF patients. MATERIALS AND METHODS A single centre observational study included 327 patients with HF. Patient mortality at one year follow up was identified and was correlated with various clinical factors including gender, anaemia, renal malfunction, ejection fraction <40% and NYHA class IV. Cox regression analysis was applied to identify relative risk of each clinical factor. RESULTS The one year post discharge mortality rate was 8.2%. NYHA Class IV, EF <40% and male gender were identified as strong predictors of mortality while anaemia and renal malfunction were reported as moderate predictors of mortality. CONCLUSION The study further confirms the significant mortality rates in HF patients even at one year follow up. We suggest that patients at high risk such as those with NYHA class IV, EF <40% and male gender be treated with more intensive treatment plans.

    The aim of this study was to explore the relationship of coexisting severe frailty and malnutrition with all-cause mortality among the oldest old in nursing homes. This study was conducted among all subjects (n=160) aged 85 years and older who lived in two nursing homes of Japan. Information about the health status of participants was gathered from history, medical documentation, test assessing frailty, according to the Canadian Study of Health and Aging-Clinical Frailty Scale (CSHA-CFS) and the Mini Nutritional Assessment Short Form (MNA-SF). Seventy five residents (46.9%) were identified as affected by coexisting severe frailty and malnutrition. After a 12-month follow-up period, 42 (26.3%) residents died. In the Cox regression analysis, coexisting severe frailty and malnutrition, and heart failure were associated with mortality during the 12-month follow-up period among the oldest old nursing home residents (adjusted HR 10.89, 95% CI 4.04-29.33, pmalnutrition are very frequent, and coexisting severe frailty and malnutrition are associated with all-cause mortality among the oldest old in nursing homes.

Studies of such factors are important to develop targeted interventions to improve health. The main purpose of this study is to explore sense of coherence (SOC in a sample of persons with morbid obesity before and after attending a patient education course and to explore the association between SOC and sociodemographic and other personal factors. Methods: In this longitudinal purposely sampled study, the participants completed questionnaires on the first day of the course and 12 months after course completion. Sixty-eight participants had valid scores on the selected variables at follow-up: SOC, self-esteem, and self-efficacy. Relationships were assessed with correlation analyses and paired and independent samples t-tests and predictors with linear regression analyses. Results: From baseline to follow-up, the total SOC score and the subdimension scores comprehensibility, manageability, and meaningfulness all increased significantly. At both time points, the SOC scores were low compared to the general population but similar to scores in other chronically ill. At baseline, a multivariate analysis showed that older age, having paid work, and higher self-esteem were directly related to higher total SOC score after controlling for other sociodemographic factors and the participants' level of self-efficacy. Multivariate analyses of the relationship between baseline predictors of SOC at 12-month follow-up, controlling for baseline SOC scores or sociodemographic or personal factors, revealed that none of these variables independently predicted SOC scores at follow-up. Conclusion: The total SOC score and its

    Full Text Available Abstract Background Hip resurfacing arthroplasty (HRA is considered a bone-preserving procedure and may eliminate proximal femoral stress shielding and osteolysis. However, in addition to implant-related stress-shielding factors, various patient-related factors may also have an effect on bone mineral density (BMD of the proximal femur in patients with HRA. Thus, we studied the effects of stem-neck angle, demographic variables, and physical functioning on the BMD of the proximal femur in a one-year follow-up. Methods Thirty three patients (9 females and 24 males with a mean (SD age of 55 (9 years were included in the study. BMD was measured two days and 3, 6, and 12 months postoperatively and 10 regions of interest (ROI were used. Stem-neck angle was analyzed from anteroposterior radiographs. Results Three months postoperatively, BMD decreased in six out of 10 regions of interest (ROI on the side operated on and in one ROI on the control side (p Conclusions After an early drop, the BMD of the upper femur was restored and even exceeded the preoperative level at one year follow-up. From a clinical standpoint, the changes in BMD in these HRA patients could not be explained by stem-neck angle or patient related factors.

A total of 108 patients were evaluated at the beginning of their CR, at 6 and 12 months after discharge. Self-report questionnaires were used to assess depression, anxiety, illness perception and work stress at each time stage. Results showed reports of depressive symptoms significantly decreased (p work stress after their RTW. Patients' psychological health and work stress need to be assessed during the CR and should be also carefully monitored after the RTW in order to identify patients' psychological and work-related barriers and facilitate a safe and successful work reintegration.

    Emerging evidence suggests that perceived injustice is a risk factor for work disability in individuals with whiplash injury. At present, however, little is known about the processes by which perceived injustice impacts on return to work. The purpose of this study was to examine whether expectancies mediated the relationship between perceived injustice and return to work in patients with whiplash injury. One hundred and fifty-two individuals (81 men, 71 women) with a primary diagnosis of whiplash injury completed self-report measures of pain intensity, perceived injustice and return-to-work expectancies following admission to a rehabilitation programme. Work status was assessed 1 year after discharge. Consistent with previous research, high scores on a measure of perceived injustice were associated with prolonged work disability. Results indicated that high perceptions of injustice were associated with low return-to-work expectancies. Causal mediation analyses revealed that expectancies fully mediated the relationship between perceived injustice and return to work. The findings suggest that intervention techniques designed to target expectancies could improve return-to-work outcomes in patients with whiplash injury. Discussion addresses the processes by which expectancies might impact on return-to-work outcomes and the manner in which negative return-to-work expectancies might be modified through intervention. The study confirms that expectancies are the mechanism through which perceived injustice impacts return to work following whiplash injury. The findings suggest that interventions designed to specifically target return-to-work expectancies might improve rehabilitation outcomes in patients with whiplash injury. © 2017 European Pain Federation - EFIC®.

    2008-07-28

    To evaluate in a twelve-month, randomized placebo-controlled study whether pure administration of phytoestrogen genistein (54 mg/day) might reduce cytogenetic biomarkers in peripheral lymphocytes of postmenopausal women. A total of 57 postmenopausal women met the criteria and were randomly assigned to receive phytoestrogen genistein (n = 30) or placebo (n = 27). There was no significant difference in age, length of time since menopause or body mass index between the two groups. After one year, plasma genistein level was 0.14 +/- 0.01 micromol/L in the control group and 0.72 +/- 0.08 micromol/L in the genistein group (P < 0.0001). At baseline, sister chromatid exchange rate was 4.97 +/- 2.17 in the control group and 4.96 +/- 1.83 in the genistein group (P = 0.89). After one year, sister chromatid exchange rate was 4.96 +/- 2.16 in the control group and 3.98 +/- 1.14 in the genistein group (P < 0.05). High frequency cells count was 3% in the genistein group and 5% in the control group (P < 0.05) at the end of the study. Chromosomal aberration frequency was 5.55% in the control group at time 0 and 5.75% in the genistein group; after one year, the figures were 5.86% in the control group and 4.5% in the genistein group (P < 0.05). After one year, there was a negative relationship between sister chromatid exchange rate and plasma levels (r = - 0.43; P < 0.05) in the genistein group. Phytoestrogen genistein has been shown in postmenopausal women to be effective in the reduction of cytogenetic biomarkers. The protective effect on genomic damage appears to be a particularly promising tool in reducing the risk of cancer.

    Falls can have devastating consequences for older people. We determined the relationship between the likelihood of fall incidents and daily-life behavior. We used wearable sensors to assess habitual physical activity and daily-life gait quality (in terms of e.g. stability, variability, smoothness and symmetry), and determined their predictive ability for time-to-first-and-second-falls. 319 older people wore a trunk accelerometer (Dynaport MoveMonitor, McRoberts) during one week. Participants further completed questionnaires and performed grip strength and trail making tests to identify risk factors for falls. Their prospective fall incidence was followed up for six to twelve months. We determined interrelations between commonly used gait characteristics to gain insight in their interpretation and determined their association with time-to-falls. For all data -including questionnaires and tests- we determined the corresponding principal components and studied their predictive ability for falls. We showed that gait characteristics of walking speed, stride length, stride frequency, intensity, variability, smoothness, symmetry and complexity were often moderately to highly correlated (r > 0.4). We further showed that these characteristics were predictive of falls. Principal components dominated by history of falls, alcohol consumption, gait quality and muscle strength proved predictive for time-to-fall. The cross-validated prediction models had adequate to high accuracy (time dependent AUC of 0.66–0.72 for time-to-first-fall and 0.69–0.76 for -second-fall). Daily-life gait quality obtained from a single accelerometer on the trunk is predictive for falls. These findings confirm that ambulant measurements of daily behavior contribute substantially to the identification of elderly at (high) risk of falling. PMID:27389583

    To assess prospectively the prognostic value of FDG PET/CT during curative-intent radiotherapy (RT) with or without concomitant chemotherapy in patients with non-small-cell lung cancer (NSCLC). Patients with histological proof of invasive localized NSCLC and evaluable tumour, and who were candidates for curative-intent radiochemotherapy (RCT) or RT were preincluded after providing written informed consent. Definitive inclusion was conditional upon significant FDG uptake before RT (PET{sub 1}). All included patients had a FDG PET/CT scan during RT (PET{sub 2}, mean dose 43 Gy) and were evaluated by FDG PET/CT at 3 months and 1 year after RT. The main endpoint was death (from whatever cause) or tumour progression at 1 year. Of 77 patients preincluded, 52 were evaluable. Among the evaluable patients, 77 % received RT with induction chemotherapy and 73 % RT with concomitant chemotherapy. At 1 year, 40 patients (77 %) had died or had tumour progression. No statistically significant association was found between stage (IIIB vs. other), histology (squamous cell carcinoma vs. other), induction or concomitant chemotherapy, and death/tumour progression at 1 year. The SUV{sub max} in the PET{sub 2} scan was the single variable predictive of death or tumour progression at 1 year (odds ratio 1.97, 95 % CI 1.25 - 3.09, p = 0.003) in multivariate analysis. The area under the receiver operating characteristic curve was 0.85 (95 % CI 0.73 - 0.94, p < 10{sup -4}). A SUV{sub max} value of 5.3 in the PET{sub 2} scan yielded a sensitivity of 70 % and a specificity of 92 % for predicting tumour progression or death at 1 year. This prospective multicentre study demonstrated the prognostic value in terms of disease-free survival of SUV{sub max} assessed during the 5th week of curative-intent RT or RCT in NSCLC patients (NCT01261598; RTEP2 study).

    Full Text Available Parkinson’s disease (PD is a neurodegenerative disease in which gait and balance disturbances are relevant symptoms that respond poorly to pharmacological treatment. The aim of this study was to investigate whether a 4-week inpatient multidisciplinary intensive rehabilitation treatment (MIRT is effective in improving balance and gait and whether improvements persist at a one-year followup. We studied 20 PD inpatients (stage 3 Hoehn-Yahr who underwent a MIRT. Outcome measures were UPDRS items for balance (30, falls (13, and walk (29, Berg Balance Scale, six-minute walking test, Timed Up and Go Test, and Comfortable-Fast gait speeds. Patients were evaluated at admission, at the end of the 4-week treatment, and at a 1-year followup. Pharmacological therapy was unchanged during MIRT and follow-up. All outcome measures improved significantly at the end of treatment. At 1-year follow-up control, UPDRS walk and Comfortable-Fast gait speeds still maintained better values with respect to admission (P=0.009, P=0.03, and P=0.02, resp., while the remaining scales did not differ significantly. Our results demonstrate that the MIRT was effective in improving balance and gait and that the improvement in gait performances was partially maintained also after 1 year.

    This 1-year cohort study investigated stability and peri-implant marginal bone level of immediately loaded mini dental implants used to retain overdentures. Each of 30 edentulous patients received 4 mini dental implants (1.8 mm × 13 mm) in the interforaminal mandibular region. The implants were immediately loaded with pre-made overdentures. Outcome measures included implant stability and bone resorption. Implant stability was measured using the Periotest Classic(®) device immediately after placement and on the 3rd and 6th weeks and the 4th, 6th and 12th months postoperatively. The peri-implant marginal bone level (PIBL) was evaluated at the implant's mesial and distal sides from the polished platform to the marginal crest. Radiographs were taken using a tailored film holder to reproducibly position the X-ray tube at the 6th week, 4th and 12th months postoperatively. The primary stability (Periotest value, PTV) measured -0.27 ± 3.41 on a scale of -8 to + 50 (lower PTV reflects higher stability). The secondary stability decreased significantly until week 6 (mean PTV = 7.61 ± 7.05) then increased significantly reaching (PTV = 6.17 ± 6.15) at 12 months. The mean PIBL measured -0.40 mm after 1 year of functional loading, with no statistically significant differences at the various follow-ups (p = 0.218). Mini dental implants placed into the interforaminal region could achieve a favorable primary stability for immediate loading. The follow-up Periotest values fluctuated, apparently reflecting the dynamics of bone remodeling, with the implants remaining clinically stable (98.3%) after 1 year of function. The 1-year bone resorption around immediately loaded MDIs is within the clinically acceptable range for standard implants. Copyright © 2014 Elsevier GmbH. All rights reserved.

    The study purpose was to examine the association between changes in depressive symptoms and changes in lifestyle-related indicators among adults with type 2 diabetes. A longitudinal survey was conducted among individuals with type 2 diabetes in Quebec. The sample consisted of 1183 subjects who responded to the baseline and 1-year follow-up telephone interviews, with complete data for depressive symptoms (Patient Health Questionnaire 9). Regression models were used to determine associations between changes in depressive symptoms and changes in lifestyle-related indicators (physical activity, body mass index (BMI)) and, perception-related indicators (control of body weight and of amount of food eaten). After 1 year, 136 subjects (11.5%) developed depression (major or minor), 118 (10%) remained depressed, 829 (70%) remained not depressed and 100 (8.5%) reverted to not depressed. Subjects who developed depression, compared with those who remained not depressed, were more likely to be inactive at baseline, remain inactive at 1 year, report a worsening of their perception of controlling body weight, report maintaining a poor perception of controlling amount of food eaten and report maintaining a poor perception of controlling body weight (p<0.05). The same factors were associated with maintenance of depression at 1 year (p<0.05). Changes in BMI were not associated with changes in depressive symptoms. Physical inactivity, perception of poor control of body weight and amount of food eaten have been found to be associated prospectively with the development and persistence of depression and, therefore, should be considered priority targets for diabetes treatment. Depression is related to the continuation of poor lifestyle and perception-related indicators. Copyright © 2013 Canadian Diabetes Association. Published by Elsevier Inc. All rights reserved.

    The results of previous cross-sectional studies suggest that free thyroxine (FT4) levels are associated with cognitive abilities (particularly attention/vigilance) during the early stages of psychosis. We aimed to explore whether hypothalamic-pituitary-thyroid hormones predict cognitive changes in a 1-year longitudinal study following first episodes of psychosis (FEP). We studied 36 FEP patients and a control group of 50 healthy subjects (HS). Plasma levels of thyroid-stimulating hormone (TSH) and FT4 were measured. Cognitive assessment was performed with the MATRICS Cognitive Consensus Cognitive Battery (MCCB). FEP patients were assessed twice (baseline and after 1year), whereas HS were assessed only once. We compared cognitive changes at 1year between three groups based on baseline FT4 levels: 1) lowest quartile (Q1, FT41.54ng/dL). No differences in TSH or FT4 levels were found between HS and FEP patients. All participants had FT4 levels within the normal range. HS outperformed FEP patients in all cognitive tasks. In relation to the relationship between FT4 levels and cognitive changes, a U-shaped pattern was observed: FEP patients from the middle quartiles (Q2-Q3) improved in attention/vigilance, whereas both extreme quartiles (Q1 and Q4) showed a worsening in this cognitive domain over time. Patients with lower FT4 (Q1) showed poorer baseline attention; therefore, lower baseline FT4 levels predicted a poorer prognosis in terms of attention performance. Our study suggests that baseline FT4 levels are associated with changes in attention and vigilance performance over one year in FEP patients.

    Full Text Available The effect of physical exercise on the treatment of depressive elderly adults has not been investigated thus far in terms of changes in cortical hemispheric activity. The objective of the present study was to identify changes in depressive symptoms, quality of life, and cortical asymmetry produced by aerobic activity. Elderly subjects with a diagnosis of major depressive disorder (DSM-IV were included. Twenty patients (70% females, 71 ± 3 years were divided into an exercise group (pharmacological treatment plus aerobic training and a control group (undergoing pharmacological treatment in a quasi-experimental design. Pharmacological treatment was maintained stable throughout the study (antidepressants and anxiolytics. Subjects were evaluated by depression scales (Beck Depression Inventory, Hamilton Depression Rating Scale, Montgomery-Asberg Depression Rating Scale and the Short Form Health Survey-36, and electroencephalographic measurements (frontal and parietal alpha asymmetry before and after 1 year of treatment. After 1 year, the control group showed a decrease in cortical activity on the right hemisphere (increase of alpha power, which was not observed in the exercise group. The exercise group showed a significant decrease of depressive symptoms, which was not observed in the control group. This result was also accompanied by improved treatment response and remission rate after 1 year of aerobic exercise associated with treatment. This study provides support for the effect of aerobic training on alpha activity and on depressive symptoms in elderly patients. Exercise facilitates the treatment of depressive elderly adults, leading to clinical and physical improvement and protecting against a decrease in cortical activity.

    Background With increase of spine surgeries, failed back surgery syndrome (FBSS) prevalence is also rising. While complementary and alternative medicine (CAM) is commonly used for low back pain (LBP), there are no studies reporting use of integrative Korean medicine in FBSS patients. Methods Patients with pain continuing after back surgery or recurring within 1 year and visual analogue scale (VAS) of LBP or leg pain of ≥6 (total n = 120) were recruited at 2 hospital sites from November 2011 to September 2014. Weekly sessions of integrative Korean medicine treatment were conducted for 16 weeks (herbal medicine, acupuncture/electroacupuncture, pharmacopuncture/bee venom pharmacopuncture, and Chuna manual therapy) with additional follow-ups at 24 weeks and 1 year. Outcome measures included VAS of LBP and leg pain (primary outcome), Oswestry Disability Index (ODI), Short-Form 36 (SF-36), medical use, and patient global impression of change (PGIC). Results VAS of LBP and leg pain improved at 6 months (LBP from 6.1±2.0 at baseline to 2.9±2.3; and leg pain from 5.4±2.6 to 2.4±2.5, respectively). Eighty patients (66.7%) showed improvement of 50% or more in main pain of LBP or leg pain from baseline. Disability and quality of life also improved at 6 months (ODI from 41.3±12.3 at baseline to 23.6±13.6; and SF-36 from 42.8±14.5 to 62.7±16.8). At 1 year follow-up, conventional medical management use decreased, improvement in pain and disability was maintained, and 79.2% reported improvement of PGIC. Conclusions Despite limitations as an observational study, integrative Korean medicine treatment showed positive results in pain, function, and quality of life of FBSS patients. PMID:28129399

    A robotic arm was developed by our laboratory for tele-operated echography on patients in locations isolated from a trained sonographer. The objective of the study was to evaluate, over a 1-year period, the use of the robotic arm for telesonography performed by a sonographer located at the University Hospital (Tours, France) on patients in two isolated medical centers 50 km away linked via the Internet. A nonsonographer operator (physician or paramedic) located the ultrasound probe attached to the robotic arm over the appropriate acoustic window for the organ of interest by rolling the whole robotic arm and mechanical support across the floor. The expert sonographer then telemanipulated the robotic arm via an Internet connection and adjusted the orientation of the probe until the most appropriate organ view for delivering a diagnosis was obtained. Three hundred telesonography examinations were performed within 1 year: 68 (22.7%) on abdominal organs, 20 (6.7%) on pelvic organs, 138 (46%) on supraaortic vessels (carotid artery), 33 (11%) on the thyroid, 30 (10%) on leg veins, and 11 (3.7%) on the kidney and urinary tract. Telesonography could not be achieved in 10 of the 300 cases due to poor image quality on obese patients or those presenting poor echogenicity. These cases were re-examined at the university hospital by a sonographer. The rate of telesonography exams over the 1-year period was 1.5 per day for the "general population" medical site and 1 per week for the "elderly patient" medical site. This study demonstrated that telesonography using a robotic arm can be routinely used for providing echographic diagnoses on patients isolated from imaging centers.

    Diabetes mellitus is a frequent comorbid conditions among patients with pneumonia living in the community.The aim of our study is to evaluate the impact of hospitalization for pneumonia on early (30 day) and late mortality (1 year) in patients with type 2 diabetes mellitus.Prospective comparative cohort study of 203 patients with type 2 diabetes hospitalized for pneumonia versus 206 patients with diabetes hospitalized for other noninfectious causes from January 2012 to December 2013 at Policlinico Umberto I (Rome). Enrolled patients were followed up to discharge and up to 1 year after initial hospital admission or death.Overall, 203 patients with type 2 diabetes admitted to hospital for pneumonia were compared to 206 patients with type 2 diabetes admitted for other causes (39.3% decompensated diabetes, 21.4% cerebrovascular diseases, 9.2% renal failure, 8.3% acute myocardial infarction, and 21.8% other causes). Compared to control patients, those admitted for pneumonia showed a higher 30-day (10.8% vs 1%, P pneumonia had a higher incidence of moderate to severe chronic kidney disease, hemodialysis, and malnutrition were more likely to present with a mental status deterioration, and had a higher number of cardiovascular events during the follow-up period. Cox regression analysis found age, Charlson comorbidity index, pH pneumonia as variables independently associated with mortality.Hospitalization for pneumonia is associated with decreased 1-year survival in patients with type 2 diabetes, and appears to be a major determinant of long-term outcome in these patients.

    The outcome of premature infants with only diffuse excessive high signal intensity (DEHSI) is not clear. We explored the relationship between DEHSI, white matter (WM) diffusion characteristics, perinatal characteristics, and neurobehavioral outcome at 1 year in a homogenous group of preterm infants without major brain abnormalities. Fifty-eight preterm infants, gestational age 29 ± 2.6 weeks, underwent an MRI at term-equivalent age (TEA). Griffiths Mental Developmental Scales, neurological assessment, and Parental Stress Index (PSI) were performed at 1 year corrected age. These measures were compared between preterm infants according to DEHSI classification (none, mild, moderate). Diffusion tensor imaging was used in major WM volumes of interest to objectively measure the degree of WM maturation. No significant differences were detected in the perinatal risk characteristics, neurobehavioral outcome, and PSI at 1 year between infants with different DEHSI classifications. In infants with DEHSI, increased axial and radial diffusivities were detected in the optic radiations, centrum semiovale, and posterior limb of the internal capsule, indicating less advanced maturation of the WM. Significant correlations were detected between the time interval from birth to MRI and the WM microstructure in infants without DEHSI. DEHSI in premature infants is neither a predictive measure for short-term adverse neurobehavioral outcome nor related to perinatal risk characteristics. Extrauterine exposure time had a differential effect on WM maturational trajectories in infants with DEHSI compared to those without. We suggest DEHSI may represent an alteration in WM maturational characteristics. Further follow-up studies may verify later consequences of DEHSI in premature infants. (orig.)

    Developmental research in music has typically centered on the study of single musical skills (e.g., singing, listening) and has been conducted with middle class children who learn music in schools and conservatories. Information on the musical development of children from different social strata, who are enrolled in community-based music programs, remains elusive. This study examined the development of musical skills in underprivileged children who were attending an El Sistema-inspired program in Los Angeles. We investigated how children, predominantly of Latino ethnicity, developed musically with respect to the following musical skills - pitch and rhythmic discrimination, pitch matching, singing a song from memory, and rhythmic entrainment - over the course of 1 year. Results suggested that participation in an El Sistema-inspired program affects children's musical development in distinct ways; with pitch perception and production skills developing faster than rhythmic skills. Furthermore, children from the same ethnic and social background, who did not participate in the El Sistema-inspired music program, showed a decline in singing and pitch discrimination skills over the course of 1 year. Taken together, these results are consistent with the idea of musical development as a complex, spiraling and recursive process that is influenced by several factors including type of musical training. Implications for future research are outlined.

    To respond to the increasing requests of non-infectious disease physicians for access to infectious diseases expertise, a hotline was created in the infectious diseases consultation (IDC) unit of the Grenoble university-affiliated hospital (GUH). This study describes the patterns of solicited consultations provided by the hotline during a 1-year period. We conducted a prospective study of consecutive solicited IDCs requested by physicians in 2008. A total of 7,863 consultations were requested by physicians over 1 year; 4,407 (56.0%) by ambulatory physicians, 2,933 (37.3%) by GUH physicians, and 523 (6.7%) by physicians in public or private hospitals. The majority of consultations were requested via cell phone (58.7%). The main reasons for requesting a consultation were related to antimicrobial treatment for hospital-based physicians and prophylaxis for ambulatory physicians (p hotline attests to an important need for such expertise consultation, both in hospitals and in ambulatory medicine.

    Long-term safety and the effects of a St. John's wort (SJW) extract Ze 117 (Hypericum perforatum) were evaluated in the treatment of patients with depression. An open multicentre safety study with 440 out-patients suffering from mild to moderate depression according to ICD-10 was conducted. Patients were treated for up to 1 year with 500 mg St. John's wort extract per day (Ze 117). Evaluation criteria were safety (adverse event frequency) and influence on depression (HAM-D, CGI). Two hundred and seventeen (49%) patients reported 504 adverse events, 30 (6%) of which were possibly or probably related to the treatment. Gastrointestinal and skin complaints were the most common events associated with treatment. No age-related difference in the safety of the applied medication was found. The long-term intake of up to 1 year of the study medication did not result in any changes in clinical chemistry and electrocardiogram recordings. Body mass index (BMI) did not change either. Mean HAM-D scores decreased steadily from 20.58 at baseline to 12.07 at week 26 and to 11.18 at week 52. Mean CGI scores decreased from 3.99 to 2.20 at week 26 and 2.19 at week 52. Therefore, St. John's wort extract ZE 117 is a safe and effective way to treat mild to moderate depression over long periods of time, and therefore seems especially suitable for a relapse prevention.

    Dow Corning SE 1700 (reinforced polydimethylsiloxane) porous structures were made by direct ink writing (DIW). The specimens (~50% porosity) were subjected to various compressive strains (15, 30, 45%) and temperatures (room temperature, 35, 50, 70°C) in a nitrogen atmosphere (active purge) for 1 year. Compression set and load retention of the aged specimens were measured periodically during the study. Compression set increased with strain and temperature. After 1 year, specimens aged at room temperature, 35, and 50°C showed ~10% compression set (relative to the applied compressive deflection), while those aged at 70°C showed 20-40%. Due to the increasing compression set, load retention decreased with temperature, ranging from ~90% at room temperature to ~60-80% at 70°C. Long-term compression set and load retention at room temperature were predicted by applying time-temperature superposition (TTS). The predictions show compression set relative to the compressive deflection will be ~10-15% with ~70-90% load retention after 50 years at 15-45% strain, suggesting the material will continue to be mechanically functional. Comparison of the results to previously acquired data for cellular (M97*, M9760, M9763) and RTV (S5370) silicone foams suggests that the SE 1700 DIW porous specimens are on par with, or outperform, the legacy foams.

    Full Text Available BACKGROUND: Football (soccer is endorsed as a health-promoting physical activity worldwide. When football programs are introduced as part of general health promotion programs, equal access and limitation of pre-participation disparities with regard to injury risk are important. The aim of this study was to explore if disparity with regard to parents' educational level, player body mass index (BMI, and self-reported health are determinants of football injury in community-based football programs, separately or in interaction with age or gender. METHODOLOGY/PRINCIPAL FINDINGS: Four community football clubs with 1230 youth players agreed to participate in the cross-sectional study during the 2006 season. The study constructs (parents' educational level, player BMI, and self-reported health were operationalized into questionnaire items. The 1-year prevalence of football injury was defined as the primary outcome measure. Data were collected via a postal survey and analyzed using a series of hierarchical statistical computations investigating associations with the primary outcome measure and interactions between the study variables. The survey was returned by 827 (67.2% youth players. The 1-year injury prevalence increased with age. For youths with parents with higher formal education, boys reported more injuries and girls reported fewer injuries than expected; for youths with lower educated parents there was a tendency towards the opposite pattern. Youths reporting injuries had higher standardized BMI compared with youths not reporting injuries. Children not reporting full health were slightly overrepresented among those reporting injuries and underrepresented for those reporting no injury. CONCLUSION: Pre-participation disparities in terms of parents' educational level, through interaction with gender, BMI, and self-reported general health are associated with increased injury risk in community-based youth football. When introduced as a general health

    Chronic obstructive pulmonary disease (COPD) is a progressive respiratory disease with an increasing prevalence worldwide. Its potential consequences, including reduced function and reduced social participation, are likely to be associated with decreased health-related quality of life (HRQoL). However, illness perceptions and self-efficacy beliefs may also play a part in determining HRQoL in persons with COPD. The aim of this study was to explore the relationships between illness perceptions, self-efficacy, and HRQoL in a sample of persons with COPD in a longitudinal perspective. The context of the study was a patient education course from which the participants were recruited. Data concerning sociodemographic variables, social support, physical activity, illness perceptions, general self-efficacy, and HRQoL were collected before the course started and 1 year after completion. Linear regression was used in the analyses. The results showed that less consequences and less symptoms (identity) were associated with higher physical HRQoL (PCS) at baseline and at 1-year follow-up. Less emotional response was similarly associated with higher mental HRQoL (MCS) at both time points. Lower self-efficacy showed a borderline significant association with higher PCS at baseline, but was unrelated to MCS at both time points. Self-efficacy showed no influence on the associations between illness perceptions and HRQoL. In conclusion, the study showed that specific illness perceptions had a stable ability to predict HRQoL in persons with COPD, whereas self-efficacy did not. The associations between illness perceptions and HRQoL were not mediated by self-efficacy.

    Little is known about the factors associated with patient compliance with nucleos(t)ide analog (NUC) treatment for chronic hepatitis B (CHB). The purpose of this study was to examine the association between sociodemographic and clinical characteristics and adherence to NUCs among patients with CHB. A total of 211 CHB patients receiving NUC monotherapy were asked to report the number of prescribed doses of medication they had taken during the last 90 days. A total of four 3-month adherence scores were averaged to obtain a combined rate of NUC adherence during a 1-year follow up period. The mean age of the patients was 29.6 years, 79% were men, and 68% had no prior NUC treatment for CHB. Females, patients without a previous NUC treatment, and those who had NUC drug resistance showed better adherence to NUC treatment, and compliance was better with telbivudine than with lamivudine and entecavir.

    Consumption of sugar-containing beverages (SCBs) in adults has been associated with an increased risk of metabolic syndrome. Although the effect of SCB on body weight in children is well established, little is known about the cardiometabolic effects in young children. We studied the associations of SCB intake at the age of 1 year with cardiometabolic health at age 6 years. This study was performed among 2,045 Dutch children from a population based prospective birth cohort. SCB intake was assessed with a semi-quantitative food frequency questionnaire at the age of 13 months and sex-specific tertiles were created. Children visited the research center at the age of 6 years. We created a continuous cardiometabolic risk factor score including: body fat percentage, blood pressure, insulin, HDL-cholesterol and triglycerides. Age-and sex-specific standard deviation (SD) scores were created for all outcomes. Multivariable linear regression was performed with adjustment for socio-demographic and lifestyle variables of mother and child. In the total population, we observed an association between higher SCB intake at 13 months of age and a higher cardiometabolic risk factor score at the age of 6 years (0.13SD (95 % CI 0.01; 0.25), highest vs. lowest tertile) After stratification by sex, we found that boys in the highest tertile of SCB intake had a higher cardiometabolic risk factor score (0.18 SD (95 % CI 0.01; 0.34)), as compared to boys in the lowest tertile of SCB intake. There was no significant association in girls. We did not find associations of SCB intake with the individual cardiometabolic risk factors in the total population, or in the stratified analyses. Higher SCB intake at 1 year of age was associated with a higher cardiometabolic risk factor score at age 6 years in boys, but not in girls. Further research on sex-specific effects of SCBs is needed.

    Aims: The aim of the following study is to evaluate the change in laser fluorescence (LF) values for extracted teeth stored in different solutions over 1 year period, to give cut-off values for different storage media at different time intervals to get them at par with the in vivo conditions and to see which medium gives best results with the least change in LF values and while enhancing the validity of DIAGNOdent in research. Materials and Methods: Ninety extracted teeth selected, from a pool of frozen teeth, were divided into nine groups of 10 each. Specimens in Groups 1-8 were stored in 1% chloramine, 10% formalin, 10% buffered formalin, 0.02% thymol, 0.12% chlorhexidine, 3% sodium hypochlorite, a commercially available saliva substitute-Wet Mouth (ICPA Pharmaceuticals) and normal saline respectively at 4°C. The last group was stored under frozen condition at −20°C without contact with any storage solution. DIAGNOdent was used to measure the change the LF values at day 30, 45, 60, 160 and 365. Statistical Analysis Used: The mean change in LF values in different storage mediums at different time intervals were compared using two-way ANOVA. Results: At the end of 1 year, significant decrease in fluorescence (P < 0.05) was observed in Groups 1-8. Maximum drop in LF values occurred between day 1 and 30. Group 9 (frozen specimens) did not significantly change their fluorescence response. Conclusions: An inevitable change in LF takes place due to various storage media commonly used in dental research at different time intervals. The values obtained from our study can remove the bias caused by the storage media and the values of LF thus obtained can hence be conveniently extrapolated to the in vivo condition. PMID:24778506

    Foods rich in sugar have been suggested to contribute to the increasing prevalence of obesity in children. The aim of this report is to investigate the dietary pattern in 1-year-old children who frequently receive foods rich in sugar but low in nutrients and to study associated demographic and parental factors. During 1977-9, 21,700 infants were invited to participate in this prospective, population-based, longitudinal cohort study. Screening questionnaires were completed for 16,070 infants after delivery. Follow-up questionnaires from 10,762 children at 1 year of age are included in the analysis. It was found that 24% of the children received sweets/pastries more often than one or two times per week. They had a higher intake of French fries, potato crisps and cream as well as a lower intake of fruit and vegetables. A frequent intake of sugar-rich, low-nutrient foods was significantly associated with several maternal factors (high intake of sweets/pastries during pregnancy, young age, mother living alone) as well as presence of older siblings. Maternal smoking during pregnancy and maternal overweight were of borderline significance. Parental education level was inversely associated with the frequency of intake of sweets/pastries in the child. Children who frequently receive sweets/pastries also have an otherwise unfavourable dietary pattern. Several parental and demographic factors were associated with this feeding pattern, especially high intake of sweets/pastries during pregnancy. Screening of pregnant women for risk predictors like consumption of sweets/pastries, young age and smoking could be possible ways of identifying children at future risk for low dietary quality.

    Nontransfusion-dependent thalassemia (NTDT) patients may develop iron overload and its associated complications despite receiving only occasional or no transfusions. The present 1-year, randomized, double-blind, placebo-controlled THALASSA (Assessment of Exjade in Nontransfusion-Dependent Thalassemia) trial assessed the efficacy and safety of deferasirox in iron-overloaded NTDT patients. A total of 166 patients were randomized in a 2:1:2:1 ratio to starting doses of 5 or 10 mg/kg/d of deferasirox or placebo. The means ± SD of the actual deferasirox doses received over the duration of the study in the 5 and 10 mg/kg/d starting dose cohorts were 5.7 ± 1.4 and 11.5 ± 2.9 mg/kg/d, respectively. At 1 year, the liver iron concentration (LIC) decreased significantly compared with placebo (least-squares mean [LSM] ± SEM, -2.33 ± 0.7 mg Fe/g dry weight [dw], P = .001, and -4.18 ± 0.69 mg Fe/g dw, P deferasirox groups, respectively (baseline values [means ± SD], 13.11 ± 7.29 and 14.56 ± 7.92 mg Fe/g dw, respectively).

    This study sought to better characterize the relationships between body mass index (BMI) and lean body mass (LBM) as assessed by serum creatinine (SCr) and mortality. The data were collected from a prospective prevalent cohort in maintenance hemodialysis patients. The study was carried out in 25 dialysis units in Rhônes Alpes area (France and Switzerland). A total of 1,205 patients were followed up for 1-year, starting July 1, 2005. Mortality as well as clinical and biological routine parameters were recorded. Kaplan-Meier, Cox model, Log rank test were used for the statistical analysis. We found that SCr was a strong predictor of mortality (P 23 (P < .001). BMI should not be used by itself but in conjunction with SCr as a surrogate of LBM to improve its morbid-mortality predictive power. LBM should also be taken into account in further survival studies carried out in hemodialysis patients. Copyright © 2011 National Kidney Foundation, Inc. Published by Elsevier Inc.

    Cyclosporin has improved graft survival after renal transplantation, but cyclosporin nephrotoxicity is a severe clinical problem. Conversion from cyclosporin to azathioprine 1 year after transplantation might improve long-term graft survival by avoidance of cyclosporin nephrotoxicity. After treatment with cyclosporin and prednisolone during the first year after renal transplantation, 106 patients were consecutively randomized to treatment with either azathioprine and prednisolone or cyclosporin and prednisolone in a prospective, controlled study during the following 5 years, i.e. 6 years after transplantation. Actuarial estimates of graft survival rates after inclusion in the study were obtained by the product-limit method of Kaplan-Meier, and the Mantel-Cox log rank test was used to compare the two treatment regimens. When the end-points in the analyses were cessation of graft function or withdrawal of immunosuppressive treatment due to side-effects, and when patients alive with graft function or who had died with a functioning graft were treated as censored observations, graft survival 5 years after inclusion in the study was 57.7 +/- 5.2% in the total material and was the same in both the azathioprine group (52.4 +/- 7.7%) and the cyclosporin group (63.3 +/- 6.7%) (log rank = 0.40, P = 0.53). When cessation of graft function was the only end-point, graft survival 5 years after inclusion in the study was 73.7 +/- 5.2% for the total material with no significant differences between the two groups (log rank = 0.58, P = 0.45).(ABSTRACT TRUNCATED AT 250 WORDS)

    Riociguat is a soluble, guanylate cyclase stimulator, approved for pulmonary arterial hypertension. In the 12-week PATENT-1 study, riociguat was well tolerated and improved several clinically relevant end-points in patients with pulmonary arterial hypertension who were treatment naïve or had been pretreated with endothelin-receptor antagonists or prostanoids. The PATENT-2 open-label extension evaluated the long-term safety and efficacy of riociguat. Eligible patients from the PATENT-1 study received riociguat individually adjusted up to a maximum dose of 2.5 mg three times daily. The primary objective was to assess the safety and tolerability of riociguat; exploratory efficacy assessments included 6-min walking distance and World Health Organization (WHO) functional class. Overall, 396 patients entered the PATENT-2 study and 324 (82%) were ongoing at this interim analysis (March 2013). The safety profile of riociguat in PATENT-2 was similar to that observed in PATENT-1, with cases of haemoptysis and pulmonary haemorrhage also being observed in PATENT-2. Improvements in the patients', 6-min walking distance and WHO functional class observed in PATENT-1 persisted for up to 1 year in PATENT-2. In the observed population at the 1-year time point, mean±sd 6-min walking distance had changed by 51±74 m and WHO functional class had improved in 33%, stabilised in 61% and worsened in 6% of the patients versus the PATENT-1 baseline. Long-term riociguat was well tolerated in patients with pulmonary arterial hypertension, and led to sustained improvements in exercise capacity and functional capacity for up to 1 year.

    We reported an acute encephalitis syndrome outbreak in Alappuzha district in Kerala, India during the year 2011. The etiology was confirmed to be West Nile virus lineage 1. Many encephalitis patients from this outbreak exhibited neurological sequelae post recovery. This study was aimed to assess the clinical outcomes of West Nile encephalitis confirmed case-patients after 1 year of acute illness. Forty West Nile virus confirmed encephalitis patients were selected from the 2011 outbreak was included in this study. Out of 40 cases, only 30 survived after 12 months. Among these 30 recovered case-patients, 27 (90%) consented for clinical follow-up and 23 (73.67%) of them consented for assessment of cognitive impairment and deposition of blood sample for antibody testing. The most common symptom observed in these patients was fatigue (25.93%). Other symptoms included dizziness (7.4%), decreased sense of hearing (7.4%) and decreased sense of smell (7.4%). Reduced power in limbs was found in 33.33% of the cases. Most of the patients (23.1%) were dependent on others for normal daily living activities. The patients also had probable risk of poor cognition (29.41%) and dementia (57.14%). None of the patients were positive for WNV specific IgM at 12 months post onset of disease. The study concluded that the long-term sequelae were noticed in WNV positive patients. Prevention effort should be focused on the elderly (≥60 years old) people who have a higher risk of severe sequelae. The state health authorities should create awareness among people in order to prevent the transmission of disease. J. Med. Virol. 88:1856-1861, 2016. © 2016 Wiley Periodicals, Inc.

However, only few studies have provided longitudinal information on sexual functioning in patients with eating disorders. To evaluate the longitudinal course of sexual functioning, and how changes in psychopathology and history of childhood abuse interact with sexual functioning in patients with anorexia nervosa (AN) and bulimia nervosa (BN). A total of 27 patients with AN and 31 with BN were assessed at baseline and at 1-year follow-up after a standard individual cognitive behavioral therapy (CBT). Subjects were studied by means of the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders IV, Female Sexual Function Index (FSFI), Eating Disorder Examination Questionnaire, Beck Depression Inventory, Spielberg's State-Trait Anxiety Inventory, Symptom Checklist-90, and Childhood Experience of Care and Abuse Questionnaire. After treatment, both patients with AN and BN showed a significant improvement in the FSFI total score (P < 0.01 for both AN and BN) and all FSFI subscales, without significant between groups differences. Patients reporting childhood sexual abuse did not show a significant improvement in sexual functioning (β = 0.05; P = 0.58). Reduction in eating disorder severity was directly associated with FSFI improvement, but only in those subjects with no history of sexual abuse (β = 0.28; P = 0.01). Eating disorder-specific psychopathology could be considered as a specific maintaining factor for sexual dysfunction in eating disorders subjects. Subjects reporting a history of childhood sexual abuse represent a subpopulation of patients with a profound uneasiness, involving body perception, as well as sexual functioning, which appeared not to be adequately challenged during standard CBT intervention. The results, though original, should be considered as preliminary, given the relatively small sample size

    A post-marketing surveillance (PMS) study was conducted with a 1-year observation period to assess the safety and efficacy of lamotrigine in routine clinical practice in patients with bipolar disorder (BD). Central enrollment method was used to recruit patients diagnosed with BD who were being treated for the first time with lamotrigine to prevent the recurrence/relapse of BD mood episodes. Adverse drug reactions (ADRs) and recurrence/relapse were assessed. Improvement of mania and depression was also assessed using the Hamilton's Rating Scale for Depression (HAM-D) and the Young Mania Rating Scale (YMRS) at treatment initiation, 4-6 months post treatment initiation, and 10-12 months post treatment initiation. A total of 237/989 patients (24.0%) reported ADRs, most commonly rash (9.1%), and the incidence of serious ADRs was 3.3% (33/989 patients). Skin disorders occurred in 130 patients (13.1%), mostly within 8 weeks post treatment. A total of 237/703 patients (33.7%) experienced recurrence/relapse of mood episodes. The 25th percentile of the time to recurrence/relapse of mood episodes was 105 days. Remission of depression symptoms (HAM-D ≤7) occurred in 147/697 patients (21.1%) at treatment initiation, rising to 361 patients (67.4%) at 10-12 months post treatment. Remission of manic symptoms (YMRS ≤13) occurred in 615/676 patients (91.0%) at treatment initiation, rising to 500 patients (97.3%) at 10-12 months post treatment. The results of this PMS study suggest that lamotrigine is a well-tolerated and effective drug for preventing recurrence/relapse of BD in clinical practice.

    Background: Osteoporosis is a chronic disease and adherence can fluctuate over time. Therefore, longer observation is necessary to investigate the stability of patients' adherence. The study aim was to compare the overall adherence (OA) to supplementation with the fixed combination of calcium and vitamin D (Ca/D) in postmenopausal women at baseline and after 1 year, and to evaluate the fluctuation of the OA in individual months. Furthermore, we studied whether adherence is influenced by signing of informed consent and routine medical check-up. Methods: This was a longitudinal, observational study. The data were obtained from the Osteocenter of University Hospital in Hradec Kralove, Czech Republic. Adherence was measured using electronic bottles type Medication Events Monitoring System (MEMS). The study was carried out in two 3-month periods; the baseline in 2013 (signing of informed consent while medical check-up) and the follow-up (medical check-up) in 2014. The adherence and adherence-related outcomes were studied in patients who had initiated osteoporosis treatment and were persistent. Results: 21 (49%) out of 43 patients who avoided drug dispenser and were persistent both at baseline and at follow-up, completed the study and were included. Median age was 76. Evaluating the whole 3-month periods, the OA did not differ significantly at baseline and at follow-up, the OA was 71 and 68%, respectively. However, the adherence in month 1 at baseline was significantly higher than the adherence in month 2 at baseline (p adherence in month 1 at follow-up (p = 0.010). Analysing the study period without month 1, a stable adherence was observed in 48% of patients. About 33% of doses were omitted at baseline and 34% at follow-up. As many as 71% of the patients took drug holidays at baseline, and 76% at follow-up. Conclusion: The OA was insufficient, around 70% both at baseline and at follow-up. One half of the patients showed a stable adherence. The patterns of non

    Full Text Available Several topical agents have been used for treating Pityriasis versicolor. But the main problem is recurrence. In this study 82 patients with recurrent and/or extensive from of infection were treated with oral Ketoconazole. 200 mg once daily for a maximum of 4 weeks. Seventeen patients have been infected for the first time and sixty five for the several times. The duration of disease in most cases (35.4% were between 1-3 years. Out of 82 studied patients only 60 cases were referred for follow up. The clinical and mycological cure were seen in 54 cases (90% after 15 days therapy. In other 6 patients after 15 days the lesions have not cured completely so the treatment was continued for other 2 weeks, but after that, only one of them referred to the clinic, which treatment extended with topical therapy.

    This study evaluated the 1-year survival and success rate of root-analogue direct laser metal sintering (DLMS) implants, placed into the extraction sockets of 15 patients. DLMS is a technology which allows solids with complex geometry to be fabricated by annealing metal powder microparticles in a focused laser beam, according to a computer-generated three-dimensional (3D) model; the fabrication process involves the laser-induced fusion of titanium microparticles, in order to build, layer-by-layer, the desired object. Cone-beam computed tomography (CBCT) acquisition and 3D image conversion, combined with the DLMS process, allow the fabrication of custom-made, root-analogue implants (RAIs). CBCT images of 15 non-restorable premolars (eight maxilla; seven mandible) were acquired and transformed into 3D models: from these, custom-made, root-analogue DLMS implants with integral abutment were fabricated. Immediately after tooth extraction, the RAIs were placed in the sockets and restored with a single crown. One year after implant placement, clinical and radiographic parameters were assessed: success criteria included absence of pain, suppuration, and exudation; absence of implant mobility and absence of continuous peri-implant radiolucency; distance between the implant shoulder and the first visible bone-to-implant contact implants were lost, for a survival rate of 100 %. All implants were stable, with no signs of infection. The good conditions of the peri-implant tissues were confirmed by the radiographic examination, with a mean DIB of 0.7 mm (±0.2). The possibility of fabricating custom-made, RAI DLMS implants opens new interesting horizons for immediate placement of dental implants.

    Full Text Available Abstract Background Musculoskeletal pain symptoms are common in children and adolescents. These symptoms have a negative impact on children's physical and emotional well-being, but their underlying aetiology and risk factors are still poorly understood. Most of the previous cohort studies were conducted among mid and/or late adolescents and were mainly focused on a specific pain location (e.g. low back pain or neck pain. The purpose of this study is to estimate occurrence of new-onset pain symptoms, in all musculoskeletal locations, in preteens and early adolescents and investigate risk factors for development of these symptoms. Methods 1756 schoolchildren (mean age 10.8 were recruited from schools in southern Finland. Information was extracted as to whether they experienced musculoskeletal pain and a total of 1192 children were identified as free of musculoskeletal pain symptoms. Information was collected on factors which could potentially predict the development of musculoskeletal pain: headache, abdominal pain, sadness/feeling down, day-time tiredness, difficulty in falling asleep, waking up during nights, level of physical activity and hypermobility. These children were followed-up 1-year later and those with new episodes of non-traumatic and traumatic musculoskeletal pain symptoms were identified. Results A total of 1113 schoolchildren (93% of baseline pain-free children were found at one-year follow-up. New episodes of musculoskeletal pain were reported by 21.5% of these children. Of them 19.4% reported non-traumatic pain and 4.0% reported traumatic pain. The neck was the most commonly reported site with non-traumatic pain, while the lower limb was the most common site for traumatic pain. The independent risk factors for non-traumatic musculoskeletal pain were headache (OR = 1.68, [95% CI 1.16–2.44] and day-time tiredness (OR = 1.53, [95% CI 1.03–2.26]. The risk factors for traumatic musculoskeletal pain were vigorous exercise (OR = 3

    To prospectively evaluate body image, sexuality, emotional reactions (anxiety, depression), and quality of life in a sample of women having increased risk for breast cancer before and 6 months and 1 year after bilateral prophylactic mastectomy (BPM), and to compare preoperative expectations of the operation with postoperative reactions concerning the impact on six areas of the women's lives. A total of 90 of 98 consecutive women who underwent BPM during October 1997 to December 2005 were included. Data were collected by self-administered questionnaires (eg, Hospital Anxiety and Depression scale, Swedish Short Term-36 Health Survey, Body Image Scale, Sexual Activity Questionnaire) before the operation (n = 81), and 6 (n = 71) and 12 months (n = 65) after BPM. Anxiety decreased over time (P = .0004). No corresponding difference was found for depression. No differences in health-related quality of life over time were found, with one exception. A substantial proportion of the women reported problems with body image 1 year after BPM (eg, self consciousness, 48%; feeling less sexually attractive, 48%; and dissatisfaction with the scars, 44%). Sexual pleasure was rated lower 1-year post-BPM as compared with before operation (P = .005), but no differences over time in habit, discomfort, or activity were found. No negative effects on anxiety, depression, and quality of life were found. Anxiety and social activities improved. Negative impact on sexuality and body image was reported.

We enrolled 103 patients (median age: 61.6 years with 108 VCF due to trauma, or traumatic VCF with associated osteoporosis. Primary outcome was back pain intensity (VAS. Secondary outcomes were Oswestry Disability Index (ODI, EuroQol-VAS, and analgesic consumption. 48 hours after surgery, a median relative decrease in pain intensity of 81.5% was observed associated with a significant reduction in analgesic intake. Improvements in disability (91.3% decrease in ODI score and in quality of life (increase 21.1% of EQ-VAS score were obtained 3 months after surgery. All results were maintained at 12 months. A reduction in the kyphotic angulation was observed postoperatively (-5.4±6.3°; p<0.001, remained at 12 months (-4.4±6.0°, p=0.002. No adverse events were implant-related and none required device removal. Three patients (2.9% experienced procedure-related complications. The overall adjacent fracture rate up to 1 year after surgery was 2.9%. The SpineJack procedure is an effective, low-risk procedure for patients with traumatic VCF allowing a fast and sustained improvement in quality of life over 1 year after surgery.

    Based on the fact that the resonant frequency of a piezoelectric crystal is the function of its surface deposit, and that the primer extends after it hybridizes with the template, the primer extension gene sensor technique was developed. The prominent feature of the technique is that fast and sensitive frequency signals are used as the monitoring system of gene hybridization and primer strand extension. Results show that this technique may be used in homologous analysis of nucleic acid, trace DNA detection, and determining the integration of DNA. It may also be used for isolation of target gene, gene mutation analysis, and predicting the location of a gene in its genome.

  2. Plasmodium vivax sub-patent infections after radical treatment are common in Peruvian patients: results of a 1-year prospective cohort study.

    Directory of Open Access Journals (Sweden)

    Peter Van den Eede

    Full Text Available BACKGROUND: There is an increasing body of literature reporting treatment failure of the currently recommended radical treatment of Plasmodium vivax infections. As P. vivax is the main malaria species outside the African continent, emerging tolerance to its radical treatment regime could have major consequences in countries like Peru, where 80% of malaria cases are due to P. vivax. Here we describe the results of a 1-year longitudinal follow up of 51 confirmed P. vivax patients living around Iquitos, Peruvian Amazon, and treated according to the Peruvian national guidelines. METHODOLOGY: Each month a blood sample for microscopy and later genotyping was systematically collected. Recent exposure to infection was estimated by detecting antibodies against the P. vivax circumsporozoite protein (CSP and all PCR confirmed P. vivax infections were genotyped with 16 polymorphic microsatellites. RESULTS: During a 1-year period, 84 recurrent infections, 22 positive also by microscopy, were identified, with a median survival time to first recurrent infection of 203 days. Most of them (71% were asymptomatic; in 13 patients the infection persisted undetected by microscopy for several consecutive months. The genotype of mostly recurrent infections differed from that at day 0 while fewer differences were seen between the recurrent infections. The average expected heterozygosity was 0.56. There was strong linkage disequilibrium (I(A(s = 0.29, p<1.10(-4 that remained also when analyzing only the unique haplotypes, suggesting common inbreeding. CONCLUSION: In Peru, the P. vivax recurrent infections were common and displayed a high turnover of parasite genotypes compared to day 0. Plasmodium vivax patients, even when treated according to the national guidelines, may still represent an important parasite reservoir that can maintain transmission. Any elimination effort should consider such a hidden reservoir.

    Full Text Available Abstract Background All medical schools must counsel poor-performing students, address their problems and assist them in developing into competent physicians. The objective of this study was to determine whether students with academic deficiencies in their M-1 year graduate more often, spend less time to complete the curriculum, and need fewer attempts at passing USMLE Step 1 and Step 2 by entering the Decompressed Program prior to failure of the M-1 year than those students who fail the M-1 year and then repeat it. Method The authors reviewed the performance of M-1 students in the Decompressed Program and compared their outcomes to M-1 students who failed and fully repeated the M-1 year. To compare the groups upon admission, t-Tests comparing the Cognitive Index of students and MCAT scores from both groups were performed. Performance of the two groups after matriculation was also analyzed. Results Decompressed students were 2.1 times more likely to graduate. Decompressed students were 2.5 times more likely to pass USMLE Step 1 on the first attempt than the repeat students. In addition, 46% of those in the decompressed group completed the program in five years compared to 18% of the repeat group. Conclusion Medical students who decompress their M-1 year prior to M-1 year failure outperform those who fail their first year and then repeat it. These findings indicate the need for careful monitoring of M-1 student performance and early intervention and counseling of struggling students.

    In a multicentre study, 146 peptic ulcer patients who had recently healed with H2 antagonists (38 gastric, 108 duodenal ulcers) received randomly for a year one of the following mucosal protecting antiulcer drugs: aceglutamide aluminium salt (AAL), zinc acexamate (ZAC) and magaldrate (MAG). Forty six patients received AAL (700 mg bid), 50 patients received ZAC (300 mg at single nocturnal dose) and 50 patients received MAG (800 mg bid). An endoscopic examination was performed at the beginning of the study and 12 months later. Clinical examinations where performed on months 3, 6 and 9, advancing the endoscopical control in case of ulcer symptoms. ZAC showed to be superior to MAG (p less than 0.05, chi-square test) in preventing relapses, with a favourable tendence in front of AAL, but without reaching statistical significance. Its important to mention the high number of withdrawals and the good tolerance of the treatments.

    Self-efficacy is important in determining which activities or situations an individual will perform or avoid. This is a case study report to explore the utility of structured education programme on strengthening self-efficacy in an older adult with chronic obstructive pulmonary disease (COPD). To comprehensively evaluate this intervention, a combined qualitative and quantitative approach was used. Although qualitative data were collected following the interview guide, quantitative data were collected by the demographic data form and the COPD Self-Efficacy Scale (CSES) at the preprogramme and postprogramme stage. The patient's self-efficacy scores improved after 8 weeks of the structured education programme and remained relatively constant on all the repeated measurements after education. Qualitative data were identified as 'difficulties' and 'facilities'. This study indicates that, by applying a self-efficacy theory, a planned education programme could be useful in improving both short-term and long-term self-efficacy in patients with COPD.

    Full Text Available BACKGROUND: Studies relating physical activity (PA to weight gain in children have produced mixed results, although there is some evidence for stronger associations with more intense physical activities. The present study tested the hypothesis that weight gain over one year in 8-10 year olds would be more strongly predicted by moderate and vigorous physical activity (MVPA than total physical activity (total PA or sedentary behaviour. METHODOLOGY: Participants were 280 children taking part in the Physical Exercise and Appetite in Children Study (PEACHES. Weight status was assessed using body mass index (BMI, fat mass index (FMI, and waist circumference (WC in school Year 4 (baseline; age 8.7 yrs and Year 5 (follow-up; age 9.7 yrs. Physical activity was measured at baseline using the Actigraph GT1M accelerometer to assess total PA (mean accelerometers counts per minute, MVPA; ≥ 4000 counts per minute and sedentary time (<100 counts per minute. PRINCIPAL FINDINGS: After adjustment for baseline BMI, SES, sex and ethnicity, MVPA was significantly associated with follow-up BMI (adjusted β  = -0.07; p = 0.002. This association was independent of total PA or sedentary time. Similar results were observed for FMI; again MVPA was significantly associated with follow up FMI (β = -0.16; p = 0.001 independent of total PA or sedentary time. The pattern was similar for WC (β = -0.07, but the association between MVPA and WC did not reach significance at p = 0.06. CONCLUSION: The results of this study strongly support promotion of MVPA in children.

    Full Text Available Abstract Background Preoperative mental health seems to have useful predictive value for Health Related Quality of Life (HRQOL after bariatric surgery. The aim of the present study was to assess pre- and postoperative psychiatric disorders and their associations with pre- and postoperative HRQOL. Method Data were assessed before (n = 127 and one year after surgery (n = 87. Psychiatric disorders were assessed by Mini International Neuropsychiatric Interview (M.I.N.I. and Structured Clinical Interview (SCID-II. HRQOL was assessed by the Short Form 36 (SF-36 questionnaire. Results Significant improvements were found in HRQOL from preoperative assessment to follow-up one year after surgery. For the total study population, the degree of improvement was statistically significant (p values Conclusion This study reports the novel finding that patients without postoperative psychiatric disorders achieved a HRQOL comparable to the general population one year after bariatric surgery; while patients with postoperative psychiatric disorders did not reach the HRQOL level of the general population. Our results support monitoring patients with psychiatric disorders persisting after surgery for suboptimal improvements in quality of life after bariatric surgery.

    Full Text Available Abstract Background Considerable proportion of patients does not respond to the cardiac resynchronization therapy (CRT. This study investigated clinical relevance of left ventricular electrode local electrogram delay from the beginning of QRS (QLV. We hypothesized that longer QLV indicating more optimal lead placement in the late activated regions is associated with the higher probability of positive CRT response. Methods We conducted a retrospective, single–centre analysis of 161 consecutive patients with heart failure and LBBB or nonspecific intraventricular conduction delay (IVCD treated with CRT. We routinely intend to implant the LV lead in a region with long QLV. Clinical response to CRT, left ventricular (LV reverse remodelling (i.e. decrease in LV end-systolic diameter - LVESD ≥10% and reduction in plasma level of NT-proBNP >30% at 12-month post-implant were the study endpoints. We analyzed association between pre-implant variables and the study endpoints. Results Clinical CRT response rate reached 58%, 84% and 92% in the lowest (≤105 ms, middle (106-130 ms and the highest (>130 ms QLV tertile (p  Conclusion LV lead position assessed by duration of the QLV interval was found the strongest independent predictor of beneficial clinical response to CRT.

    Depression is found to be present in up to 44% of brain tumor patients during their illness process. Anxiety as a comorbid psychiatric disorder with depression has formerly been studied, but phobia or obsessive-compulsive symptoms among brain tumor patients have not yet been noticed. By using a clinical prospective database of primary brain tumor patients (n=77) we studied the level of depression, anxiety, obsessionality (traits and symptoms) and phobic anxiety symptoms. Psychiatric symptoms were assessed before tumor operation as well as at three months and at one year after operation. The presence of comorbid anxiety, obsessionality and phobic anxiety symptoms was assessed before operation and at follow-ups in depressed and non-depressed patients, separately. Before tumor operation 16% of the patients had depression according to Beck Depression Inventory (BDI), while 10% had depression at three months and 15% at one year after operation. The depressed patients had statistically significantly higher anxiety scores and phobic scores at all three measurement points compared to corresponding scores among non-depressed brain tumor patients. The mean obsessionality scores among depressed brain tumor patients were significantly higher when measured before operation and at one year after the operation compared to non-depressed patients. To our knowledge, this is the first study so far in which comorbidity of psychiatric symptoms has been shown among depressive brain tumor patients. Concurrent comorbid conditions have been shown to be associated with increased severity, morbidity and chronicity of depression. It is recommended that treatment of depressive patients complicated with comorbid psychiatric disorders be planned by psychiatric units.

    Background: The presence of keratinized tissue around dental implants is more than desirable either from a functional and aesthetic point of view, making soft tissue grafting a common practice in implant rehabilitation. Autogenous soft tissue grafting procedures are usually associated with high morbidity. Aim of this study was to assess the efficacy of a xenogeneic collagen matrix as a substitute for soft tissue grafting around dental implants. Methods: 15 consecutive patients underwent a vestibuloplasty and grafting, both in the mandible and the maxilla, with a collagen matrix. Results: The primary endpoint was to evaluate the resorption of the graft along with the re-epithelization grafted area. The percentage of the resorption was 44,4%, with a mean gain in vestibular height of 3 mm. Secondary endpoints evaluated the clinical appearance, the hemostatic effect and the post-operative pain. All subjects referred minimal pain with no bleeding. No adverse reaction nor infection were noted. Conclusion: This study showed that the used collagen matrix can find major interest in those patients who need a greater aesthetic outcome as the matrix has a perfect integration with the surrounding tissues. Furthermore it is strongly recommended for those patients who can bear little pain. Clinical Significance: Post-operative morbidity of autologous grafts is the biggest concern of this type of surgery. The possibility to use a soft tissue substitute is a great achievement as morbidity decreases and bigger areas can be treated in a single surgery. The present study showed the efficacy of a collagen matrix as this kind of substitute. PMID:27583050

    To prevent falls among older people, we developed a new fall-risk assessment, the "Ordered Multi-Stepping Over Hoop (OMO)" test. The aims of this study were preliminary: to investigate the association of the OMO with cognitive and physical function and to investigate whether the OMO could predict incidents of falling. Fifty-nine community-dwelling older people (mean age = 88.0 ± 0.87, female = 49) were recruited. We assessed cognitive and physical function including the OMO test at baseline and monitored the falls of participants during a 12-month follow-up period from the baseline. We investigated whether the OMO was associated with cognitive function, physical function, and incidents of falling. To investigate whether the OMO could predict incidents of falling, a receiver operating characteristic analysis was conducted. The OMO time in fallers was significantly slower than for non-fallers. There were significant correlations between slower OMO times and lower physical functions and executive function. The area under the ROC curve in the OMO was 0.71 (p OMO identified those more likely to fall. The OMO time was correlated with cognitive function, physical function, and incidents of falling. Our preliminary study indicates that the OMO may help to make a distinction between fallers and non-fallers among older people as effectively as other tests.

    Post-traumatic stress symptoms (PTSS) have been identified as a meaningful indicator of distress in cancer survivors. Distinct from young adult survivors of childhood cancer, young people diagnosed with cancer as adolescents and young adults (AYAs) face unique psychosocial issues; however, there is little published research of PTSS in the AYA population. This study examines prevalence and predictors of PTSS among AYAs with cancer. As part of a longitudinal study of AYAs with cancer, 151 patients aged 15-39 years completed mailed surveys at 6 and 12 months post-diagnosis. Severity of PTSS was estimated at 6 and 12 months post-diagnosis. Multiple regression analyses were conducted to investigate the predictive effects of socio-demographic and clinical characteristics on changes in PTSS over time. At 6 and 12 months, respectively, 39% and 44% of participants reported moderate to severe levels of PTSS; 29% had PTSS levels suggestive of post-traumatic stress disorder. No significant differences in severity of PTSS between 6 and 12 months were observed. Regression analyses suggested that a greater number of side effects were associated with higher levels of PTSS at 6 months. Currently receiving treatment, having surgical treatment, diagnosis of a cancer type with a 90-100% survival rate, remaining unemployed/not in school, and greater PTSS at 6 months were associated with higher levels of PTSS at 12 months. Post-traumatic stress symptoms were observed as early as 6 months following diagnosis and remained stable at 12-month follow-up. The development of early interventions for reducing distress among AYA patients in treatment is recommended. Copyright © 2012 John Wiley & Sons, Ltd.

    This study aimed to evaluate the impact of thulium:yttrium-aluminum-garnet (Tm:YAG) (RevoLix®) laser prostatectomy for the treatment of benign prostatic obstructions on erectile function (EF). A total of 208 patients who underwent Tm:YAG laser prostatectomies participated in this study. All cases were evaluated preoperatively and at 3, 6, and 12 months postoperatively using the International Prostate Symptom Score (IPSS), quality of life (QoL) score, and the International Index of Erectile Function (IIEF-5) questionnaires. Patients were divided into groups A (severe erectile dysfunction [ED]), B (moderate ED), and C (mild-to-normal ED), according to their IIEF-5 scores. The median patient ages were 69, 65, and 62 years in groups A, B, and C, respectively. Significant improvements occurred in the IPSS and QoL score within the groups during the 12-month follow-up period. The IIEF-5 scores at 3 months postoperatively were lower than the preoperative scores in groups B and C. The IIEF-5 scores subsequently improved during the 12-month follow-up period. The slope of the relationship between the IIEF-5 score and the time since Tm:YAG laser prostatectomy had a ß value of 0.2210 (95% confidence interval 0.103 to 0.338, p = 0.0003); hence, each postoperative month was associated with an increase of 0.2210 in the IIEF-5 score. The IIEF-5 scores gradually increased and reached the preoperative levels by the 12-month follow-up assessment. Although the IIEF-5 score dropped significantly during the first 3 months postoperatively, it improved over the following 12 months. Tm:YAG laser prostatectomy did not impact on EF ultimately.

    Full Text Available Abstract Background Chronic neck pain is a common condition associated not only with a decrease in neck muscle strength, but also with decrease in health-related quality of life (HRQoL. While neck strength training has been shown to be effective in improving neck muscle strength and reducing neck pain, HRQoL among patients with neck pain has been reported as an outcome in only two short-term exercise intervention studies. Thus, reports on the influence of a long-term neck strength training intervention on HRQoL among patients with chronic neck pain have been lacking. This study reports the effect of one-year neck strength training on HRQoL in females with chronic neck pain. Methods One hundred eighty female office workers, 25 to 53 years of age, with chronic neck pain were randomized to a strength training group (STG, n = 60, endurance training group (ETG, n = 60 or control group (CG, n = 60. The STG performed high-intensity isometric neck strengthening exercises with an elastic band while the ETG performed lighter dynamic neck muscle training. The CG received a single session of guidance on stretching exercises. HRQoL was assessed using the generic 15D questionnaire at baseline and after 12 months. Statistical comparisons among the groups were performed using bootstrap-type analysis of covariance (ANCOVA with baseline values as covariates. Effect sizes were calculated using the Cohen method for paired samples. Results Training led to statistically significant improvement in the 15D total scores for both training groups, whereas no changes occurred for the control group (P = 0.012, between groups. The STG improved significantly in five of 15 dimensions, while the ETG improved significantly in two dimensions. Effect size (and 95% confidence intervals for the 15D total score was 0.39 (0.13 to 0.72 for the STG, 0.37 (0.08 to 0.67 for the ETG, and -0.06 (-0.25 to 0.15 for the CG. Conclusions One year of either strength or endurance training seemed

    Full Text Available Abstract Background Low back pain (LBP and leisure time physical activity (LTPA are considered to be closely related, and clinical guidelines for the treatment of acute LBP recommend patients stay physically active. However, the documentation for this recommendation is sparse and based on studies involving patient populations. The purpose of the study was (1 to investigate the correlation between LBP and LTPA on a weekly basis over the course of a year in a high-risk group of cleaners; and (2 to investigate if maintaining LTPA during an episode of acute LBP has a positive effect on LBP intensity in the subsequent 4 weeks. Methods 188 cleaners consented to participate in a 52-week text message survey about hours of LTPA and intensity of LBP (from 0 to 9 over the previous 7 days. The correlation between LBP and LTPA was calculated by Pearson correlation coefficient. During an episode of acute LBP, a mixed effect logistic regression model was used to investigate whether cleaners who maintain LTPA have a lower pain intensity and higher probability of returning to initial pain intensity within the following four weeks compared with cleaners who decrease LTPA during acute LBP. Results The correlation between weekly LTPA and LBP data was negative, but numerically low (r = -0.069 and statistically insignificant (p = 0.08. Among the 82 cleaners experiencing at least one episode of acute LBP, those maintaining LTPA during an episode of acute LBP did not have a lower pain intensity (average LBP intensity difference between groups of 0.06; 95% confidence interval (95% CI of -0.417 to 0.539 or higher probability of returning to initial pain level (Odds ratio 1,02; 95% CI of 0.50 to 2.09 in the following four weeks compared with cleaners decreasing LTPA during acute LBP. Conclusions Hours of LTPA and intensity of LBP measured on a weekly basis throughout a year showed no close correlation. Maintaining LTPA during an episode of acute LBP did not result in a

DESIGN: Prospective cohort, non-interventional study. METHODS: 132 treatment-naïve patients who received treatment for AMD-CNV and PCV were included. All patients underwent standardized examination procedures including retinal imaging at baseline and follow-up. AMD-CNV and PCV were defined on fundus fluorescein angiography and indocyanine green angiography at baseline. Patients were treated according to standard of care.We report the visual acuity (VA and optical coherence tomography (OCT measurements at baseline, month 3 and month 12 The factors influencing month 12 outcomes were analyzed. MAIN OUTCOME MEASURE: Type of treatment, number of Anti-vascular endothelial growth factor (VEGF treatments, visual outcome over one year. RESULTS: Anti-VEGF monotherapy was the initial treatment in 89.1% of AMD-CNV, but only 15.1% of PCV. The mean number of anti-VEGF injections up to month 12 was 3.97 (4.51 AMD-CNV, 3.43 PCV, p = 0.021. Baseline OCT, month 3 OCT and month 3 VA were significant in determining continuation of treatment after month 3. At month 12, mean VA improved from 0.82 (∼20/132 at baseline to 0.68 (∼20/96 at month 12 (mean gain 6.5 ETDRS letters, p = 0.002. 34.2% of eyes (38/113 eyes gained ≥15 ETDRS letters and 14.4% (16/113 eyes lost ≥15 ETDRS letters.

Recurrence was noted in 103 patients (19% after gradual withdrawal of AED, over a period of 3-4 months. 424 patients (81% did not have recurrence. The recurrence rate was influenced adversely by factors like adolescent age and later onset seizures, pre-treatment duration of symptoms more than 3 years, pre-treatment precipitating factors like emotional stress, lack of sleep and meals (however, number in each group is small, positive family history of epilepsy, focal neurodeficit, absence and myoclonic plus grandmal type of clinical seizures, paroxysmal generalized spike and wave discharges and generalized short polyspike and wave discharges in the pretreatment EEG, atrophic changes on CT brain scan (in small numbers, head trauma at birth or later and hereditary factors as etiology of epilepsy, and more than 30 number of seizures before achieving the remission. Factors like, sex, frequency of seizures, period of remission i.e. two years or more and number of drugs used to achieve remission, did not have any significant adverse effect. However, in the last parameter 95% remission was achieved by one or a combination of two drugs (72% and 23% respectively.

    The prognosis of transient loss of consciousness (LOC) was studied in a one-year follow-up survey. Included were adult patients referred by primary health care physicians for a non-acute specialist consultation during the 2-year period from 01.10.1999 to 30.9.2001. The main outcome measures were recurrence of LOCs during the follow-up, fear of recurrence, injuries, and employment. Altogether, 109 consecutive patients were followed and 39 (36%) suffered a recurrence during the one-year follow-up: 17 (30%) with syncope, 16 (43%) with seizure and six (38%) with uncertain type of LOC. The first ever seizure recurred in 5/9 (56%) during the first year, but only 1 of 17 (6%) first syncope attacks. There was no difference in the recurrence rate if the patient had had previous attacks prior to the index LOC. Injuries, mainly minor, were associated with LOCs in 56% of patients. The risk of injury was highest (83%) with alcohol-related seizures. The unemployment rate was especially high in the seizure group. Fear of recurrence was more common at the beginning than at the end of the follow-up. Seizures recur relatively often, but also recurrent syncope needs more attention--both may cause fear and lead to injuries.

    Full Text Available Introduction. Chronic functional instability—characterized by repeated ankle inversion sprains and a subjective sensation of instability—is one of the most common residual disabilities after an inversion sprain. However, whether surgical reconstruction improves sensorimotor control has not been reported to date. The purpose of this study was to assess functional improvement of chronic ankle instability after surgical reconstruction using the remnant ligament. Materials and Methods. We performed 10 cases in the intervention group and 20 healthy individuals as the control group. Before and after surgical reconstruction, we evaluated joint position sense and functional ankle instability by means of a questionnaire. Results and Discussion. There was a statistically significant difference between the control and intervention groups before surgical reconstruction. Three months after surgery in the intervention group, the joint position sense was significantly different from those found preoperatively. Before surgery, the mean score of functional ankle instability in the intervention group was almost twice as low. Three months after surgery, however, the score significantly increased. The results showed that surgical reconstruction using the remnant ligament was effective not only for improving mechanical retensioning but also for ameliorating joint position sense and functional ankle instability.

    Marine long-chained n-3 polyunsaturated fatty acids (PUFA) are recognized for their cardio-protective effects, including potential lowering of blood pressure. We hypothesized that higher habitual fish intake and n-3 PUFA plasma levels were associated with lower blood pressure and being less likely to receive antihypertensive medication after one-year follow-up. In this prospective study of 115 patients, we assessed 24 h ambulatory and central blood pressure, plasma phospholipid fatty acid composition using gas chromatography and participants completed a food frequency questionnaire, including fish-eating habits. All measurements were repeated at one-year follow-up. At baseline, patients consuming fish ≥2 times per month for dinner had significantly higher plasma levels of total marine n-3 PUFA, docosahexaenoic acid and eicosapentaenoic acid as well as significantly lower central blood pressure and a trend towards lower peripheral blood pressure. At follow-up, 21 patients (18%) without antihypertensive medication had significantly higher plasma levels of n-3 PUFA, docosahexaenoic acid and eicosapentaenoic acid as well as a higher, but still acceptable 24 h ambulatory blood pressure (137/85 mmHg) compared to subjects receiving antihypertensive medication. The untreated group was more prone to take fish oil capsules and increased their plasma levels of n-3 PUFA compared to baseline. In patients with newly diagnosed, untreated hypertension, regular fish consumption was accompanied by lower blood pressure. After one year, patients without antihypertensive medication were characterized by a significant increase and higher plasma levels of n-3 PUFA. This supports a blood pressure-lowering effect and suggests an increase in marine n-3 PUFA intake as part of non-pharmacological treatment of hypertension.

    To evaluate intravitreal aflibercept injections (IAI; also called VEGF Trap-Eye) for patients with macular edema secondary to central retinal vein occlusion (CRVO). Randomized controlled trial. This multicenter study randomized 189 patients (1 eye/patient) with macular edema secondary to CRVO to receive 6 monthly injections of either 2 mg intravitreal aflibercept (IAI 2Q4) (n = 115) or sham (n = 74). From week 24 to week 52, all patients received 2 mg intravitreal aflibercept as needed (IAI 2Q4 + PRN and sham + IAI PRN) according to retreatment criteria. The primary endpoint was the proportion of patients who gained ≥15 ETDRS letters from baseline at week 24. Additional endpoints included visual, anatomic, and quality-of-life NEI VFQ-25 outcomes at weeks 24 and 52. At week 24, 56.1% of IAI 2Q4 patients gained ≥15 letters from baseline compared with 12.3% of sham patients (P < .001). At week 52, 55.3% of IAI 2Q4 + PRN patients gained ≥15 letters compared with 30.1% of sham + IAI PRN patients (P < .001). At week 52, IAI 2Q4 + PRN patients gained a mean of 16.2 letters of vision vs 3.8 letters for sham + IAI PRN (P < .001). The most common adverse events for both groups were conjunctival hemorrhage, eye pain, reduced visual acuity, and increased intraocular pressure. Monthly injections of 2 mg intravitreal aflibercept for patients with macular edema secondary to CRVO resulted in a statistically significant improvement in visual acuity at week 24, which was largely maintained through week 52 with intravitreal aflibercept PRN dosing. Intravitreal aflibercept injection was generally well tolerated. Copyright © 2013 Elsevier Inc. All rights reserved.

    Full Text Available Background: Whether Vitamin D supplementation in prediabetes subjects prevents the development of diabetes is a matter of debate, and the results are inconsistent. This open-label, randomized study in subjects with prediabetes evaluated the effect of 12 months of Vitamin D supplementation on glycemic parameters and progression of prediabetes to diabetes in an ethnically homogeneous Kashmiri population. Materials and Methods: A total of 147 subjects were diagnosed as prediabetes out of which 137 subjects were randomized to receive in addition to standard lifestyle measures, either Vitamin D 60,000 IU weekly for 4 weeks and then 60,000 IU monthly (n = 69 or no Vitamin D (n = 68. Fasting plasma glucose (FPG, 2-h plasma glucose and A1C levels were estimated at 0, 6 and 12 months. Changes in FPG, 2-h plasma glucose, A1C level and the proportion of subjects developing diabetes were assessed among 129 subjects. Results: At 12 months, A1C levels were significantly lesser (5.7% ± 0.4% in the Vitamin D supplemented group when compared with non-Vitamin D supplemented (6.0% ± 0.3%. Similarly, FPG (97 ± 7 and 2-h plasma glucose (132 ± 16 were significantly less in Vitamin D supplemented group as compared with non-Vitamin D supplemented group (FPG = 116 ± 6 and 2-h plasma glucose = 157 ± 25 at 12 months. Nine out of 65 in non-Vitamin D supplemented and seven out of 64 in the Vitamin D supplemented group developed diabetes. Conclusions: Vitamin D supplementation in prediabetes subjects significantly lowered FPG, 2-h plasma glucose and A1C levels.

    The aim of this study was to describe the clinical course of patients with chronic, non-specific neck pain undergoing a public health covered, exercise-based rehabilitation program and to identify predictors of poor outcome. A prospective cohort study was carried out on patients with non-specific neck pain (6 months or longer), referred by their general practitioner to a 6-session program, including education and individually tailored exercise. The primary outcome measure for the course of neck pain was the Northwick neck pain questionnaire (NPQ) administered on baseline, discharge, and 1 year from discharge. Poor outcome was defined as NPQ score improving neck pain history, and the clinical features described by NPQ. From January 2008 to June 2009, 212 patients were consecutively assessed for eligibility: 178 were enrolled and 162 completed follow-up (mean age = 65.3; 75% women). Baseline NPQ average score (40.7 + 17.1) improved by MCID on discharge (26.1 + 16.3) and at 1 year (28.5 + 17.3%). The poor outcome was reported by 45% patients on discharge and by 56% at follow-up. Pain-related medication intake independently predicted poor short- (OR 4.24; 95% CI 1.83-9.84; p = 0.001) and long-term (OR 2.69; 95% CI 1.19-6.06; p = 0.017) outcome, and catastrophizing (OR 2.91; 95% CI 1.31-6.48; p = 0.009) predicted poor outcome at 1 year. Our cohort of patients with chronic neck pain undergoing an exercise-based rehabilitation program reported improvement by or beyond MICD-NPQ in 55% cases on discharge and in 44% cases at 1 year. Poor outcome was predicted by pain-related medication intake in the short and long term, and by catastrophizing in the long term.

    Full Text Available Izabela Kozicka, Tomasz Kostka Department of Geriatrics, Medical University of Lodz, Lodz, Poland Purpose: To assess the relative role of handgrip strength (HGS, quadriceps muscle power (Pmax, and optimal shortening velocity (υopt in maintaining functional abilities (FAs in older adults living in a long-term care home over a 1-year follow-up. Subjects and methods: Forty-one inactive older institutionalized adults aged 69.8±9.0 years participated in this study. HGS, Pmax, υopt, cognitive function using the Mini-Mental State Examination, depressive symptoms using the Geriatric Depression Scale, nutritional status using the Mini Nutritional Assessment (MNA, and physical activity (PA using the Seven-Day Physical Activity Recall Questionnaire were assessed at baseline and at 1-year follow-up. FAs were assessed with activities of daily living (ADL, instrumental ADL, and Timed Up & Go test. Results: Both at baseline and at follow-up, FAs were related to age, HGS, Pmax/kg, υopt, MNA, and PA. These associations were generally similar in both sexes. As revealed in multiple regression analysis, υopt was the strongest predictor of FA, followed by Pmax/kg, PA, and MNA. FA deteriorated after 1 year as measured by ADL and Timed Up & Go test. Pmax and υopt, but not HGS, also decreased significantly after 1 year. Nevertheless, 1-year changes in FAs were not related to changes in HGS, Pmax, υopt, or PA. Conclusion: The 1-year period of physical inactivity among older institutionalized adults was found to have a negative effect on their FAs, Pmax, and υopt. The present study demonstrates that Pmax and, especially, υopt correlated with FAs of older adults more than HGS, both at baseline and at follow-up. Despite this, 1-year natural fluctuations of PA, Pmax, and υopt are not significant enough to influence FAs in inactive institutionalized older adults.

    Developmental dysplasia of the hip (DDH) is associated with an increased risk of early hip osteoarthritis (OA). We aimed to examine the outcome at the completion of growth in a cohort of children who had residual acetabular dysplasia at age 1 year following early treatment for neonatal instability of the hip (NIH). We examined 21 of 30 subjects who had been treated with the von Rosen splint neonatally for NIH and had residual acetabular dysplasia at age 1 year. Mean follow-up time was 21 years (range 17-24). Signs of OA and acetabular dysplasia were assessed by radiography. Cartilage quality was assessed by delayed Gadolinium Enhanced Magnetic Resonance Imaging of Cartilage (dGEMRIC), a tool for molecular imaging of cartilage quality, at 1.5 T. Patient reported outcome (PRO) was assessed by the 12-item WOMAC score. No study participant had radiographic OA (defined as Kellgren-Lawrence grade ≥2) or minimum joint space width (JSW) ≤2 mm. The mean dGEMRIC index was 630 ms (95% CI: 600-666, range: 516-825) suggesting good cartilage quality. The mean 12-item WOMAC score was 1.2. Two of three radiographic measurements of DDH correlated positively to the dGEMRIC index. Children treated neonatally for NIH have good hip function and no signs of cartilage degeneration at 21-year follow-up, despite residual dysplasia at age 1 year. Unexpectedly, radiographic signs of dysplasia were associated with better cartilage quality, as assessed with dGEMRIC. This may indicate cartilage adaptation to increased mechanical stress in mild hip dysplasia. Copyright © 2015 Osteoarthritis Research Society International. Published by Elsevier Ltd.

    Surgical repair for large rotator cuff tear remains challenging due to tear size, altered muscle mechanical properties, and poor musculotendinous extensibility. Insufficient extensibility might lead to an incomplete reconstruction; moreover, excessive stresses after repair may result in repair failure without healing. Therefore, estimates of extensibility of cuff muscles can help in pre-surgical planning to prevent unexpected scenarios during surgery. The purpose of this study was to determine if quantified mechanical properties of the supraspinatus muscle using shear wave elastography (SWE) could be used to predict the extensibility of the musculotendinous unit on cadaveric specimens. Forty-five fresh-frozen cadaveric shoulders (25 intact and 20 with rotator cuff tear) were used for the study. Passive stiffness of 4 anatomical regions in the supraspinatus muscle was first measured using SWE. After detaching the distal edge of supraspinatus muscle from other cuff muscles, the detached muscle was axially pulled with the scapula fixed. The correlation between the SWE modulus and the extensibility of the muscle under 30 and 60N loads was assessed. There was a significant negative correlation between SWE measurements and the experimental extensibility. SWE modulus for the anterior-deep region in the supraspinatus muscle showed the strongest correlation with extensibility under 30N (r=0.70, P.001) and 60N (r=0.68, P.001). Quantitative SWE assessment for the supraspinatus muscle was highly correlated with extensibility of musculotendinous unit on cadaveric shoulders. This technique may be used to predict the extensibility for rotator cuff tears for pre-surgical planning. Copyright © 2017 Elsevier Ltd. All rights reserved.

    The purpose of this study was to evaluate the effect of a secondary reduction of the femoral component size on flexion and extension gaps intraoperatively in posterior-stabilized total knee arthroplasty (PS-TKA) monitored by computer-assisted surgery. The authors hypothesized that cutting additional bone on the posterior femoral condyle may increase the extension gap due to the posterior capsule and soft tissue loosening. Reduction of the femoral component size was performed by additional 4-in-1 cuts after the PS-TKA on 15 cadaveric knees using a ligamentous tension device with the aid of computer-assisted surgery. Measurements of the medial and lateral flexion gaps, as well as the medial and lateral extension gaps, were recorded before and after reducing the femoral component size. Trial components were used from a mobile-bearing total knee system.After reducing the femoral component size, the medial and lateral flexion and extension gaps measured larger than their initial size. The mean increases of the medial extension and flexion gaps and the lateral extension and flexion gaps were 1.3 ± 0.9, 1.0 ± 1.2, 1.1 ± 1.2, and 1.3 ± 1.3 mm, respectively; all 4 differences were significant (P ≤ .05). Surgeons should be aware of the effect of downsizing components intraoperatively because it might lead to an extension laxity. Thus, a downsizing of the femoral component may compromise the postoperative stability of TKA.

    The difficulties of treating recurrent and/or infected incisional hernias are well known in surgical practice. Several surgical techniques and various types of grafts are available for surgeons. This study presents a new surgical technique option together with the results of the 1-year follow-up. The primary aim of the study is to present the surgical technique of the procedure suitable for the treatment of recurrent and/or infected incisional hernias. The secondary aim is to determine the recurrence rate and analyse the surgical complications. The tertiary aim is to present the quality of life test results performed 3, 6 and 12 months after the surgery. The authors evaluated the results of 36 recurrent and/or infected incisional hernia surgeries (11 men, average age 60.6 years; 25 women, average age 58.9 years) performed with their own surgical method in the framework of a tightly controlled, prospective, interventional and observational consecutive cohort study conducted between 1 January 2011 and 31 December 2013 at a university surgical department. The study evaluates the results of the 1-year follow-up period. All 36 patients had at least one recurrence of abdominal wall hernia; 12 of them also had concurrent infection of the synthetic graft and a complicating fistula. The mean BMI was 31.82 kg/m(2) (25.2-43.5 kg/m(2)). The average size of the abdominal wall defect was 145.9 cm(2) (59-275 cm(2)). The abdominal wall reconstruction was performed using an autologous, double-layer dermal flap. The grafts, which had been inserted during previous surgeries, were removed completely. The autologous dermal tissue was prepared using the flap harvested during dermolipectomy. The reconstruction was achieved using a tension-free technique. The essence of the abdominal wall reconstruction is the completion of the abdominal wall defect by a double-layer autologous dermal flap. The original abdominal wall defect was not closed by direct sutures. The quality of the

    Background: Concern exists regarding gallstones as an adverse event of very-low-calorie diets (VLCDs; gallstones requiring hospital care and/or cholecystectomy in a commercial weight loss program using VLCD or low-calorie diet (LCD). Design: A 1-year matched cohort study of consecutively enrolled adults in a commercial weight loss program conducted at 28 Swedish centers between 2006 and 2009. A 3-month weight loss phase of VLCD (500 kcal per day) or LCD (1200–1500 kcal per day) was followed by a 9-month weight maintenance phase. Matching (1:1) was performed by age, sex, body mass index, waist circumference and gallstone history (n=3320:3320). Gallstone and cholecystectomy data were retrieved from the Swedish National Patient Register. Results: One-year weight loss was greater in the VLCD than in the LCD group (−11.1 versus −8.1 kg; adjusted difference, −2.8 kg, 95% CI −3.1 to −2.4; Pgallstones requiring hospital care occurred in the VLCD and LCD groups, respectively, (152 versus 44/10 000 person–years; hazard ratio, 3.4, 95% CI 1.8–6.3; Pgallstone events, 38 (61%) resulted in cholecystectomy (29 versus 9; hazard ratio, 3.2, 95% CI 1.5–6.8; P=0.003; number-needed-to-harm, 151, 95% CI 94–377; Pgallstones (2.5, 95% CI 1.3–5.1; P=0.009) and became borderline for cholecystectomy (2.2, 95% CI 0.9–5.2; P=0.08). Conclusion: The risk of symptomatic gallstones requiring hospitalization or cholecystectomy, albeit low, was 3-fold greater with VLCD than LCD during the 1-year commercial weight loss program.

    Once-daily topical brimonidine tartrate (BT) gel 0.5% was shown to be efficacious and safe for the treatment of erythema of rosacea in previous studies including a 4-week treatment phase. In the present 1-year study, we aimed to assess the long-term safety and efficacy of the treatment. Subjects with moderate to severe erythema of rosacea were instructed to apply topical BT gel 0.5% once daily for 12 months. Severity of erythema and adverse events (AEs) were evaluated. Approximately 345 subject years of exposure to BT gel 0.5% was achieved in the study. The incidence of AEs and AEs judged to be related to the study drug was higher at the beginning and decreased over the course of the study. Similar safety profiles were observed between the subjects who had received or not received concomitant therapies for the inflammatory lesions of rosacea. Effect of topical BT gel 0.5% on erythema severity was observed after the first application and the durability of the effect was maintained until the end of the study at month 12, with no tachyphylaxis observed. In conclusion, once-daily topical BT gel 0.5% is safe and consistently effective for the long-term treatment of moderate to severe erythema of rosacea, even in the presence of concomitant therapies for the inflammatory lesions of rosacea.

    Full Text Available Abstract Background In recent years a number of costs of stroke studies have been conducted based on incidence or prevalence and estimating costs at a given time. As there still is a need for a deeper understanding of factors influencing these costs the aim of this study was to calculate the direct and indirect costs in a younger ( Methods Fifty-eight patients included in a study of home rehabilitation and followed for 1 year after discharge from the rehabilitation unit, were interviewed about their use of health care services, assistance, medications and assistive devices. Costs (defined as the cost for society were calculated. A linear regression of cost and variables of functioning, ability, community integration and health-related quality of life was done. Results Inpatient care contributed substantially to the direct cost with a mean length of stay of 92 days. Rehabilitation during the first year constituted of an average of 28 days in day clinics, 38 physiotherapy sessions and 20 occupational therapy sessions. The total direct mean cost was 80 020 € and the indirect cost 35 129 €. The direct costs were influenced by the process skill (the ability to plan and perform a given task and to adapt when needed and presence of aphasia. Indirect costs for informal care giving increased for patients with a lower health-related quality of life as well as a low score on home integration. Conclusion Costs are high in this group of young (

    To investigate the clinical impact of 1-year certolizumab pegol (CZP) therapy added to the first year of 2-year methotrexate (MTX) therapy, compared with 2-year therapy with MTX alone. MTX-naïve patients with early rheumatoid arthritis (RA) with poor prognostic factors were eligible to enter Certolizumab-Optimal Prevention of joint damage for Early RA (C-OPERA), a multicentre, randomised, controlled study, which consisted of a 52-week double-blind (DB) period and subsequent 52-week post treatment (PT) period. Patients were randomised to optimised MTX+CZP (n=159) or optimised MTX+placebo (PBO; n=157). Following the DB period, patients entered the PT period, receiving MTX alone (CZP+MTX→MTX; n=108, PBO+MTX→MTX; n=71). Patients who flared could receive rescue treatment with open-label CZP. 34 CZP+MTX→MTX patients and 14 PBO+MTX→MTX patients discontinued during the PT period. From week 52 through week 104, significant inhibition of total modified total Sharp score progression was observed for CZP+MTX versus PBO+MTX (week 104: 84.2% vs 67.5% (p<0.001)). Remission rates decreased after CZP discontinuation; however, higher rates were maintained through week 104 in CZP+MTX→MTX versus PBO+MTX→MTX (41.5% vs 29.3% (p=0.026), 34.6% vs 24.2% (p=0.049) and 41.5% vs 33.1% (p=0.132) at week 104 in SDAI, Boolean and DAS28(erythrocyte sedimentation rate) remission. CZP retreated patients due to flare (n=28) showed rapid clinical improvement. The incidence of overall adverse events was similar between groups. In MTX-naïve patients with early RA with poor prognostic factors, an initial 1 year of add-on CZP to 2-year optimised MTX therapy brings radiographic and clinical benefit through 2 years, even after stopping CZP.

    2014-07-01

    Full Text Available One of the more familiar means to capitalise on the reputation of an established brand, is to use the brand name to introduce new products in a different product category. Various factors impact on the extent to which brand extensions can benefit from or even detract from the original brand. The focus of this study is on brand associations as means to extend the original brand. A qualitative study, in contrast with the quantitative nature of most earlier studies, was used to elicit an unbiased picture of consumers’ associations of a brand. The use of a qualitative study also made it possible to follow up on and probe  the comments made by respondents. The study examined consumers’ reactions to a variety of fictitious extensions for four different popular brands (Coca-Cola, Benetton, Yamaha, and Kellogg’s. The key rationale for this study was to observe how consumers’ associations of a brand impact on their evaluation of extensions to that brand. Six propositions were investigated. Because of the considerable extent of the findings generated by the qualitative approach, the research is reported in two parts. The findings on three propositions were reported in Kasper, Strepp and Terblanche (2005. The findings on the remaining three propositions are described in this second part of the reported research.

    Since 1981, 20 infants younger than 1 year of age received 26 orthotopic liver transplants. Immunosuppression was with cyclosporine and corticosteroids. Thirteen (65%) of the recipients were discharged from the hospital. To date, 12 (60%) of the 20 recipients are surviving, with follow-up of 1 to 56 months (average 14 months). The 5-year actuarial survival is 53.8%. The allograft liver function in the majority of surviving infants is excellent. The predominant causes of mortality were primary nonfunction of the allograft (three patients) and sepsis (three). Major morbidity was caused by hepatic artery thrombosis (five patients), gastrointestinal complications (six), biliary tract complications (five), and bacterial and viral infections (13). Six patients underwent retransplantation; three of these six survived. Results could be improved by prevention of hepatic artery thrombosis, by decreasing the incidence of sepsis, and by procurement of more and better suited pediatric donors. PMID:3550022

    Economic feasibility assessments represent a key issue for selecting which wastewater treatment processes should be implemented. The few applications that exist focus on the positive economic value of externalities, overlooking the existence of negative externalities. However, wastewater treatment plants (WWTPs) consume a significant amount of energy, contributing to climate change. In this context, as a pioneering approach, greenhouse gas emissions (GHG) have been incorporated as a negative externality of wastewater treatment. Within this framework, this study aims to compare the economic feasibility of five technologies, both intensive and extensive, for small communities. The results show that both the investment and operation costs are higher for intensive than for extensive technologies. Moreover, significant differences in the value of negative externalities were observed. This study demonstrates that from an economic perspective, constructed wetland is the most suitable option for treating wastewater in small agglomerations.

    To report interim 1-year results from a 3-year surveillance study evaluating safety, efficacy, and persistence of long-term mirabegron for overactive bladder (OAB). Patients starting treatment with mirabegron for urinary urgency, daytime frequency, and urgency incontinence associated with OAB were registered and followed up for 3 years. Data were collected on adverse drug reactions (ADR), changes in OAB symptoms, changes in Overactive Bladder Symptom Score (OABSS), and treatment discontinuations. Treatment persistence rates were calculated by Kaplan-Meier analysis. Eighty-one ADR were observed in 72/1139 patients (6.3%) through 1 year of mirabegron treatment, with the incidence highest during the first month. No significant change in residual urine volume was observed at any observation point up to 1 year of mirabegron treatment. Mirabegron was deemed "effective" in 883/1091 patients (80.9%) at 1 year/discontinuation. Total OABSS was decreased with statistical significance at 3 months, 6 months, and 1 year, or at discontinuation (P < 0.001 at each time point). Kaplan-Meier treatment persistence rates were 84.8% at 3 months, 77.6% at 6 months, and 66.0% at 1 year. Treatment persistence rates were similar for male and female patients but significantly higher for patients aged ≥65 years (67.3%; n = 908) compared with those aged <65 years (59.8%; n = 231; log-rank test: P = 0.032). Long-term OAB treatment with mirabegron was well-tolerated, with effectiveness maintained through 1 year. Mirabegron treatment persistence was higher than has been previously reported, and was greater in patients aged ≥65 years compared with those aged <65 years. © 2017 John Wiley & Sons Australia, Ltd.

    In this experiment, freezing injuries in winter for the 1-year-old seedlings of 19 landscaping tree species common in the central Shanxi were compared to examine the winter survival ability of landscaping tree seedlings and to provide a practical reference guide for seedling propagation in the area. The results indicated: (1) the 1-year-old seedlings of Acer mono, Platycladus orientalis, Fraxinus pennsylvanica, Euonymus bungeanus, Koelreuteria paniculata, Gleditsia japonica, Syringa reticulata and Ligustrum obtusifolum could safely survive winter in the area, without or with little freezing injuries. Seedling propagation was appropriate for these species in the area. (2) The seedlings of Firmiana simplex and Hibiscus syriacus suffered most serious freezing injuries, resulting in very low survival rates despite under protection in the winter. Seedling propagation was not appropriate for the two species in the area. (3) The seedlings of Cornus alba, Albizia julibrissin, Pterocarya stenoptera, Acer negundo, Platanus acerifolia, Cercis chinensis, Toona sinensis, Lagerstroemia indica and Catalpa bungei suffered varying degrees of freezing injuries and needed to be observed in the second even third winters to decide if seedling propagation was appropriate for these species in this area. (4) The freezing injury index with properly weighted class 4 could more objectively reflect and compare freezing injuries of the different tree seedlings. The results from this study could provide a practical reference guide for seedling propagation of the 19 species in the area.%为了检测山西中部园林绿化树种播种苗的越冬特性,进而为苗木培育提供实用参考依据,对19种山西中部地区常见的园林绿化树种的1年生播种苗进行了越冬受冻害比较研究.结果表明:(1)五角枫、侧柏、洋白蜡、丝棉木、栾树、山皂荚、暴马丁香和水蜡的1年生播种苗可以在该地区安全越冬,不受冻害影响或受冻害影响很

    Through the study of relationship between agricultural technology extension and the development of agricultural modernization,urbanization and industrialization,it is found that agricultural technology extension is an important means to achieve synchronous development of agricultural modernization,urbanization and industrialization. Based on the sample data in China during 1978-2011,we perform the empirical analysis using VAR model and cointegration analysis and impulse response methods. The results show that there is a long-term positive equilibrium relationship between agricultural technology extension and the development of agricultural modernization,urbanization and industrialization,and agricultural technology extension plays a role in promoting agricultural modernization,urbanization and industrialization to varying degrees. Finally,it is concluded that there is a need to establish efficient agricultural technology extension mechanism and diversified agricultural technology extension investment mechanism to make agricultural technology extension better promote China’s agricultural modernization,urbanization and industrialization.

  7. An Optimal Observing System Study for the Kuroshio Extension using Particle Filters

    2010-05-01

    The Kuroshio Extension - the eastward-flowing free jet formed when the warm waters of the Kuroshio separate from the Japanese coast - reveals bimodal behavior. It changes from an elongated, energetic meandering jet into a weaker, unstable jet with a reduced zonal penetration. Many of its characteristics, e.g. the decadal period and the more stable character of the elongated state, are also observed in a reduced-gravity ocean model of the northern Pacific basin with a schematic Japanese coastline driven by a constant double-gyre wind field. The success of this idealized model suggests that intrinsic nonlinear mechanisms play a major role in determining the meander pattern of the mean flow. The low complexity of the model makes it ideal to perform an observing system study. Here, we take a new approach by using particle filters to assimilate observations into the model. An ensemble of model states is integrated over time from an initial distribution. The first approach is to pick one run as the synthetic truth. Observations are produced from this synthetic truth with an additional observation error. The particle filter technique adjusts the weight of each ensemble run - each particle - according to the observation value and the error distribution. From the ensemble and its weight distribution the expectation and probability distribution of the state vector can be computed. As the ensemble itself is not altered by the filter, different sets of observations, e.g. with different geometrical configurations, locations and/or time resolutions, can be analyzed a posteriori. The particle filter analyses allows us to identify which observations have a large impact on reconstructing the true state of Kuroshio Extension. More precisely, which observations contribute to a (local) reduction in the entropy of the ensemble. In a way each observation is then linked to an area of influence, which permits for determining the flow of information. We will present results where

  8. How sedimentation affects rift segment interaction during oblique extension: a 4D analogue modelling study

    Zwaan, Frank; Schreurs, Guido; Adam, Jürgen

    2017-04-01

    During the early stages of rifting, rift segments may form along non-continuous and/or offset pre-existing weaknesses. It is important to understand how these initial rift segments interact and connect to form a continuous rift system. Previous modelling of rift interaction structures has shown the dominant influence of oblique extension, promoting rift segment linkage (e.g. Zwaan et al., 2016) and eventual continent break-up (Brune et al., 2012). However, these studies did not incorporate sedimentation, which can have important implications for rift evolution (e.g. Bialas and Buck, 2009). Here we present a series of analogue model experiments investigating the influence of sedimentation on rift interaction structures under oblique extension conditions. Our set-up involves a base of compressed foam and plexiglass that forces distributed extension in the overlying analogue materials when the model sidewalls move apart. A sand layer simulates the brittle upper crust and a viscous sand/silicone mixture the ductile lower crust. One of the underlying base plates can move laterally allowing oblique extension. Right-stepping offset and disconnected lines of silicone (seeds) on top of the basal viscous serve as inherited structures since the strong sand cover is locally thinner. We apply syn-rift sediments by filling in the developing rift and transfer zone basins with sand at fixed time steps. Models are run either with sedimentation or without to allow comparison. The first results suggest that the gross structures are similar with or without sedimentation. As seen by Zwaan et al. (2016), dextral oblique extension promotes rift linkage because rift propagation aligns itself perpendicular to the extension direction. This causes the rift segments to grow towards each other and to establish a continuous rift structure. However, the structures within the rift segments show quite different behaviour when sedimentation is applied. The extra sediment loading in the rift basin

    We aimed to assess patient acceptance and effectiveness of a 12-month structured management program in patients after an acute coronary syndrome (ACS) event who were treated in a special setting of office-based cardiologists. The program comprised patient documentation with a specific tool (Bundesverband Niedergelassener Kardiologen [German Federation of Office-Based Cardiologists] cardiac pass with visit scheduling) shared by the hospital physician and the office-based cardiologist, the definition of individual treatment targets, and the systematic information of patients in order to optimize adherence to therapy. Participating centers (36 hospitals, 60 office-based cardiologists) included a total of 1,003 patients with ACS (ST-segment elevation myocardial infarction [STEMI] 44.3%, non-ST-segment elevation myocardial infarction [NSTEMI] 39.5%, unstable angina pectoris [UA] 15.2%, and unspecified 1.0%). During follow-up, treatment rates with cardiac medication remained high in all groups, with dual antiplatelet therapy in 91.0% at 3 months, 90.0% at 6 months, and 82.8% at 12 months, respectively. Twelve months after the inclusion, a total of 798 patients (79.6%) still participated in the program. Eighteen patients (1.8%) had died after discharge from hospital (6 in the STEMI, 12 in the NSTEMI group), while for 58 the status was unknown (5.8%). Based on a conservative approach that considered patients with unknown status as dead, 1-year mortality was 7.6%. Recurrent cardiac events were noted in 14.9% at 1 year, with an about equal distribution across STEMI and NSTEMI patients. In conclusion, patients' acceptance of the ProAcor program as determined by adherence rates over time was high. Treatment rates of recommended medications used for patients with coronary heart disease were excellent. The 1-year mortality rate was comparatively low.

    A kinematic study of cervical spine. The aim of the study was to confirm the interesting manifestation observed in the dynamic images of the cervical spine movement from full-extension to full-flexion. To further explore the fine motion of total process of cervical spine movement with the new concept of Cobb angular velocity (CAV). Traditionally range of motion (ROM) is used to describe the cervical spine movement from extension to flexion. It is performed with only end position radiographs. However, these radiographs fail to explain how the elaborate movement happens. The dynamic images of the cervical spine movement from full-extension to full-flexion of 12 asymptomatic subjects were collected. After transforming these dynamic images to static lateral radiographs, we overlapped C7 cervical vertebrae of each subject and divided the total process of cervical spine movement into five equal partitions. Finally, CAV values from C2/3 to C6/7 were measured and analyzed. A broken line graph was created based on the data of CAV values. A simple motion process was observed in C2/3 and C3/4 segments. The motion processes of C4/5 and C5/6 segments exhibited a more complex track of "N" and "W" than the other segments. The peak CAV values of C4/5 and C5/6 were significantly greater than the other segments. From C2/3 to C6/7, the peak CAV value appeared in sequence. The intervertebral movements of cervical spine did not take a uniform motion form when the cervical spine moved from full-extension to full-flexion. From C2/3 to C6/7, the peak CAV value appeared in order. The C4/5 and C5/6 segments exhibited more complex kinematic characteristics in sagittal movement. This leads to C4/5 and C5/6 more vulnerable to injury and degeneration. We had a hypothesis that there was a positive correlation between injury/degeneration and complexity of intervertebral movement in the view of CAV. N/A.

    This open-label extension evaluated the long-term efficacy and tolerability of rufinamide in patients with Lennox-Gastaut syndrome (LGS) who had previously completed a 12-week double-blind study. In total, 124 patients (aged 4-37 years), receiving 1-3 concomitant antiepileptic drugs, were treated with rufinamide approximately 25-60 mg/kg/day. Efficacy was assessed by seizure frequency; tolerability by adverse events (AEs) and laboratory tests. Overall, patients were treated with rufinamide for a median (range) of 432 (10-1149) days. Reductions in seizure frequency were observed throughout the study; during the last 12 months of treatment, 41.0% and 47.9% of patients had > or = 50% reduction in total and tonic-atonic seizure frequency, respectively. The most common AEs were vomiting (30.6%) and pyrexia (25.8%). In this open-label extension, rufinamide appeared to be an effective long-term adjunctive therapy for the treatment of LGS-associated seizures in children and young adults.

  17. A model study of the Gulf Stream Extension intrinsic low-frequency variability

    2010-05-01

    A process-oriented model study aimed at understanding aspects of the intrinsic low-frequency variability of the Gulf Stream Extension is presented. Reduced-gravity and two-layer shallow water eddy-permitting models are implemented in a domain spanning the latitudes from 10°S to 60°N, with schematic coastlines representing correctly the large-scale shape of the continental boundaries. The forcing, provided by a time-independent climatological wind stress field, is obtained from 41 years (1961-2001) of ECMWF Re-Analysis data. In the two-layer model a Deep Western Boundary Current is introduced through boundary forcing. The dissipative mechanisms are the lateral eddy viscosity (with coefficient A) and the interfacial friction (with coefficient F) and, in the two-layer model, also the bottom friction. Sensitivity experiments are carried out by varying A and F, and the results are interpreted also in terms of dynamical systems theory. For sufficiently high dissipation a steady western boundary current and corresponding extension jet are obtained: their comparison with AVISO altimeter data provides experimental validation of the model setup. Decreasing A and F leads to a first Hopf bifurcation and to the successive transition to chaotic fluctuations characterized by interannual time scales. A thorough analysis is carried out also by considering previous work on more idealized double-gyre flows.

    Full Text Available This extension trial is an open-label observational trial of 20 subjects with fibromyalgia who undertook level 2 Chaoyi Fanhuan Qigong (CFQ training following an earlier controlled trial of level 1 CFQ. Subjects practiced 60 min/day for 8 weeks and continued some daily practice for 6 months. Quantitative measures, assessed at baseline, 8 weeks, 4 and 6 months, were of pain, impact, sleep, physical and mental functions, and practice time. Qualitative comments also were recorded. Compared to baselines, CFQ practice led to significant improvements in pain, impact, sleep, and physical function in the 13 subjects (65% who completed the trial; changes were present at 8 weeks and were maintained for the 6-month trial duration. A highly motivated subgroup of N=5, who practiced the most, had the best outcomes in terms of end symptomology, and qualitative comments indicated health benefits in other domains as well. Qualitative comments by the remaining N=8 trial completers and N=7 withdrawals indicate different experiences with the practice. This extension trial indicates that diligent CFQ practice over time produces significant health gains in fibromyalgia in a subset of individuals. Future studies will need to address factors that might predispose to favourable outcomes.

  19. OpenARC: Extensible OpenACC Compiler Framework for Directive-Based Accelerator Programming Study

    Energy Technology Data Exchange (ETDEWEB)

    Lee, Seyong [ORNL; Vetter, Jeffrey S [ORNL

    2014-01-01

    Directive-based, accelerator programming models such as OpenACC have arisen as an alternative solution to program emerging Scalable Heterogeneous Computing (SHC) platforms. However, the increased complexity in the SHC systems incurs several challenges in terms of portability and productivity. This paper presents an open-sourced OpenACC compiler, called OpenARC, which serves as an extensible research framework to address those issues in the directive-based accelerator programming. This paper explains important design strategies and key compiler transformation techniques needed to implement the reference OpenACC compiler. Moreover, this paper demonstrates the efficacy of OpenARC as a research framework for directive-based programming study, by proposing and implementing OpenACC extensions in the OpenARC framework to 1) support hybrid programming of the unified memory and separate memory and 2) exploit architecture-specific features in an abstract manner. Porting thirteen standard OpenACC programs and three extended OpenACC programs to CUDA GPUs shows that OpenARC performs similarly to a commercial OpenACC compiler, while it serves as a high-level research framework.

    Introduction Good alveolar ridge is a prerequisite for successful conventional/ implant supported partial/complete denture. Extensively resorbed ridges with shallow vestibule and high insertion of muscles in to the ridge crest, leads to failure of prosthesis. Success of prosthesis depends on surgical repositioning of mucosa and muscle insertions, which increases the depth of vestibule and denture flange area for retention. So, the study was planned to provide good attached gingiva with adequate vestibular depth using Modified Kazanjian Vestibuloplasty (MKV). Aim To evaluate efficacy of MKV technique for increasing vestibular depth in anterior mandible so that successful prosthesis can be delivered. Efficacy of the technique was evaluated through operating time required, vestibular depth achieved, scarring or relapse and any postoperative complications associated with the healing. Materials and Methods Total of 10 patients were included in the study, who had minimum 20mm of bone height and less than 5mm of vestibular depth for MKV procedure. The results were tabulated and statistical analysis was carried out to assess vestibular depth achieved i.e. from crest of the ridge to junction of attached mucosa both pre and postoperatively. The study results were compared with existing literature. Results Healing of raw surface was uneventful with satisfactory achievement of vestibular depth. The average gain in vestibular depth was 11 mm. The patients had good satisfaction index for prosthesis. Conclusion Even in the era of implant prosthesis Modified Kazanjian technique is worth to practice to achieve good results and overcorrection is not required as that of standard Kazanjian technique. It provides adequate attached gingiva for successful prosthesis. Extension of vestibular depth enables fabrication of better denture flange with improved oral hygiene. This technique does not require hospitalization and additional surgery for grafts. PMID:27042579

  3. A simple extension of contraction theory to study incremental stability properties

    DEFF Research Database (Denmark)

    Jouffroy, Jerome

    Contraction theory is a recent tool enabling to study the stability of nonlinear systems trajectories with respect to one another, and therefore belongs to the class of incremental stability methods. In this paper, we extend the original definition of contraction theory to incorporate...... in an explicit manner the control input of the considered system. Such an extension, called universal contraction, is quite analogous in spirit to the well-known Input-to-State Stability (ISS). It serves as a simple formulation of incremental ISS, external stability, and detectability in a differential setting....... The hierarchical combination result of contraction theory is restated in this framework, and a differential small-gain theorem is derived from results already available in Lyapunov theory....

    Here we report on preliminary results of an extensive study of fragmentation cross sections measurements useful for medical and space applications. In particular, we looked at the hadrontherapy and space radiation research. Indeed, the measure of fragmentation cross sections is an important information to estimate how this process modifies dose distributions and biological effectiveness, both inside human body and spacecraft. In this picture we started to measure the fragmentation of 12C beam accelerated by the Superconducting Cyclotron at 32 AMeV, 62 AMeV on 12C, 207Pb and 197Au at the INFN Laboratory Nazionali del Sud in Catania (Italy). Preliminary comparison between absolute cross-sections measured for the systems: 12C+207Pb at 32AMeV and for 12C+197Au at 62AMeV is performed.

    Mesozoic faulting has been recognised in several Irish sedimentary basins as part of the northward propagation of the Atlantic rift system. However, the contribution of older structural elements remains poorly constrained. The present study documents the succession of extensional phases in the northern part of the Porcupine Basin sensu largo, offshore west of Ireland, in which structural inheritance and fault reactivation is commonly observed. The correlation of 2D and 3D seismic lines with exploration wells enables the precise definition of four overprinted extensional systems that link to specific tectonic stages identified along the Irish margin. The Porcupine Basin opened through a thickened continental crust that evolved during the Palaeozoic with the Caledonian and Variscan orogenic cycles. Extension initiated during the Carboniferous by reactivation of old structures, resulting in the migration of depocentres bounded by E-W, NE-SW and N-S structural trends. Subsequent episodic rifting occurred during several discrete events. The first rift episode, of Late Triassic to Early Jurassic age, is restricted to the North Porcupine Basin and most likely reactivated E-W structures of Caledonian age. Synrift sediments were generally deposited in a littoral setting that progressively deepened through time. The second episode, much more pronounced, occurred during the Upper Jurassic to lowermost Cretaceous (Neocomian). It resulted in shallow to deep marine deposition controlled by structural directions recognised in Caledonian and Variscan terranes. A third rift phase, evidenced by thick clastic deposition, locally occurred during the Aptian and finally died out with the opening of the Bay of Biscay located to the south of the region. A series of extensional megacycles are recognised from seismic unconformities and faulting geometries. Initial extension strongly followed the structural architecture of the continental crust (i.e. ancient folds, thrusts or orogenic fronts

    Tactile expertise, resulting from extensive use of hands, has previously been shown to improve tactile perception in blind people and musicians and to be associated with changes in the central processing of tactile information. This study investigated whether expertise, due to precise and deliberate use of the fingers at work, relates to improved tactile perception and whether this expertise interacts with age. A tactile pattern and a frequency discrimination task were conducted while ERPs were measured in experts and nonexperts of two age groups within middle adulthood. Independently of age, accuracy was better in experts than in nonexperts in both tasks. Somatosensory N70 amplitudes were larger with increasing age and for experts than for nonexperts. P100 amplitudes were smaller in experts than in nonexperts in the frequency discrimination task. In the pattern discrimination task, P300 difference wave amplitude was reduced in experts and late middle-aged adults. In the frequency discrimination task, P300 was more equally distributed in late middle-aged adults. We conclude that extensive, dexterous manual work leads to acquisition of tactile expertise and that this expertise might delay, but not counteract, age effects on tactile perception. Comparable neurophysiological changes induced by age and expertise presumably have different underlying mechanisms. Enlarged somatosensory N70 amplitudes might result from reduced inhibition in older adults but from enhanced, specific excitability of the somatosensory cortex in experts. Regarding P300, smaller amplitudes might indicate fewer available resources in older adults and, by contrast, a reduced need to engage as much cognitive effort to the task in experts.

    Full Text Available Purpose of study: The main purpose of this study is to investigate the impact of brand extensions on parent brand image. For this purpose Johnson is selected as parent brand for current study. The selected brand extensions are Johnson shampoo, Johnson’s isotonic drinks, Johnson’s sportswear and Johnson’s suntan lotion. Research Methodology: sample was selected from Bradford, UK. Sample consists of consumer of Johnson including males as well as female. Total sample size is 250 and data was collected through self administered questionnaires. Convenience sampling was selected as sampling technique. Results: Correlation analysis indicated negative impact of brand extension on parent brand image if brand extension is done in different brand categories. Perceived brand quality and perceived brand fit of the extension also affect the parent brand image. Conclusion: It is concluded that if brand extension is done in the same product category of parent brand then there is possibly high acceptance for the brand extension rather than in the different product categories.

  11. Study of muon bundles from extensive air showers with the ALICE detector at CERN LHC

    2016-05-01

    ALICE is one of four large experiments at the CERN Large Hadron Collider, specially designed to study particle production in ultra-relativistic heavy-ion collisions. Located 52 meters underground with 28 meters of overburden rock, it has also been used to detect muons produced by cosmic-ray interactions in the upper atmosphere. The large size and excellent tracking capability of the ALICE Time Projection Chamber are exploited to study the muonic component of extensive air showers. We present the multiplicity distribution of these atmospheric muons and its comparison with Monte Carlo simulations. The latest version of the QGSJET hadronic interaction model was used to simulate the development of the resulting air showers. High multiplicity events containing more than 100 reconstructed muons were also studied. Similar events have been studied in previous underground experiments such as ALEPH and DELPHI at LEP without satisfactory explanations for the frequency of the highest multiplicity events. We demonstrate that the high muon-multiplicity events observed in ALICE stem from primary cosmic rays with energies above 1016 eV and that the frequency of these events can be successfully described by assuming a heavy mass composition of primary cosmic rays in this energy range.

    Traditionally, functional gastrointestinal disorders (FGIDs) are conceptualised as originating in the brain via stress pathways (brain-to-gut). It is uncertain how many with irritable bowel syndrome (IBS) and functional dyspepsia (FD) have a gut origin of symptoms (gut-to-brain pathway). To determine if there is a distinct brain-to-gut FGID (where psychological symptoms begin first) and separately a distinct gut-to-brain FGID (where gut symptoms start first). A prospective random population sample from Newcastle, Australia who responded to a validated survey in 2012 and completed a 1-year follow-up survey (n = 1900). The surveys contained questions on Rome III IBS and FD and the Hospital Anxiety and Depression Scale. We found that higher levels of anxiety and depression at baseline were significant predictors of developing IBS (OR = 1.31; 95% CI 1.06-1.61, P = 0.01; OR = 1.54; 95% CI 1.29-1.83, P intestinal features in many cases. © 2016 John Wiley & Sons Ltd.

    The Tunka Radio Extension (Tunka-Rex) is a radio detector at the TAIGA facility located in Siberia nearby the southern tip of Lake Baikal. Tunka-Rex measures air-showers induced by high-energy cosmic rays, in particular, the lateral distribution of the radio pulses. The depth of the air-shower maximum, statistically depends on the mass of the primary particle, is determined from the slope of the lateral distribution function (LDF). Using a model-independent approach, we have studied possible features of the one-dimensional slope method and tried to find improvements for the reconstruction of primary mass. To study the systematic uncertainties given by different primary particles, we have performed simulations using the CONEX and CoREAS software packages of the recently released CORSIKA v7.5 including the modern high-energy hadronic models QGSJet-II.04 and EPOS-LHC. The simulations have shown that the largest systematic uncertainty in the energy deposit is due to the unknown primary particle. Finally, we studied the relation between the polarization and the asymmetry of the LDF.

    A growing body of international literature points to the importance of a system approach to improve the quality of care in primary health care settings. Continuous Quality Improvement (CQI) concepts and techniques provide a theoretically coherent and practical way for primary care organisations to identify, address, and overcome the barriers to improvements. The Audit and Best Practice for Chronic Disease (ABCD) study, a CQI-based quality improvement project conducted in Australia's Northern Territory, has demonstrated significant improvements in primary care service systems, in the quality of clinical service delivery and in patient outcomes related to chronic illness care. The aims of the extension phase of this study are to examine factors that influence uptake and sustainability of this type of CQI activity in a variety of Indigenous primary health care organisations in Australia, and to assess the impact of collaborative CQI approaches on prevention and management of chronic illness and health outcomes in Indigenous communities. The study will be conducted in 40-50 Indigenous community health centres from 4 States/Territories (Northern Territory, Western Australia, New South Wales and Queensland) over a five year period. The project will adopt a participatory, quality improvement approach that features annual cycles of: 1) organisational system assessment and audits of clinical records; 2) feedback to and interpretation of results with participating health centre staff; 3) action planning and goal setting by health centre staff to achieve system changes; and 4) implementation of strategies for change. System assessment will be carried out using a System Assessment Tool and in-depth interviews of key informants. Clinical audit tools include two essential tools that focus on diabetes care audit and preventive service audit, and several optional tools focusing on audits of hypertension, heart disease, renal disease, primary mental health care and health promotion

The aims of the extension phase of this study are to examine factors that influence uptake and sustainability of this type of CQI activity in a variety of Indigenous primary health care organisations in Australia, and to assess the impact of collaborative CQI approaches on prevention and management of chronic illness and health outcomes in Indigenous communities. Methods/design The study will be conducted in 40–50 Indigenous community health centres from 4 States/Territories (Northern Territory, Western Australia, New South Wales and Queensland over a five year period. The project will adopt a participatory, quality improvement approach that features annual cycles of: 1 organisational system assessment and audits of clinical records; 2 feedback to and interpretation of results with participating health centre staff; 3 action planning and goal setting by health centre staff to achieve system changes; and 4 implementation of strategies for change. System assessment will be carried out using a System Assessment Tool and in-depth interviews of key informants. Clinical audit tools include two essential tools that focus on diabetes care audit and preventive service audit, and several optional tools focusing on audits of hypertension, heart disease, renal

    The two Helios probes traveled at variable longitudinal and radial separations through the inner heliosphere. They collected most valuable high resolution plasma and magnetic field data for an entire solar cycle. The mission is still so successful that no other missions will collect the same kind of data in the next 20 years. One of the subjects studied after the success of the Helios mission was the identification of more than 390 shock waves driven by Interplanetary Coronal Mass Ejections (ICMEs). Combining the data from both probes, we make a statistical study for the extension of the shock waves in the interplanetary medium. For longitudinal separations of 90° we found a cutoff value at this angular separation. A shock has 50% of chance to be observed by both probes and the same probability for not being observed by two spacecrafts at the same time, when the angle between them is around 90°. We describe the dependence of the probability for shocks to be observed by both probes with decreasing spacecraft separation. Including plasma data from the ISEE-3 and IMP-8 spacecrafts improves our statistical evaluation substantially.

    The Tunka Radio Extension (Tunka-Rex) is a radio detector at the TAIGA facility located in Siberia nearby the southern tip of Lake Baikal. Tunka-Rex measures air-showers induced by high-energy cosmic rays, in particular, the lateral distribution of the radio pulses. The depth of the air-shower maximum, which statistically depends on the mass of the primary particle, is determined from the slope of the lateral distribution function (LDF). Using a model-independent approach, we have studied possible features of the one-dimensional slope method and tried to find improvements for the reconstruction of primary mass. To study the systematic uncertainties given by different primary particles, we have performed simulations using the CONEX and CoREAS software packages of the recently released CORSIKA v7.5 including the modern high-energy hadronic models QGSJet-II.04 and EPOS-LHC. The simulations have shown that the largest systematic uncertainty in the energy deposit is due to the unknown primary particle. Finally, we...

    Knee osteoarthritis results in changes that affect balance. It has been reported that osteoarthritis worsens proprioception and increases the risk of falling. The objective of this study was to assess changes in balance among patients with knee osteoarthritis at 1 year after total knee arthroplasty (TKA) surgery and its relationship with clinical variables. This prospective, observational study evaluated 44 patients before and 1 year after TKA. Variables analyzed included age, body mass index, pain, range of motion for both knees, bilateral quadriceps and hamstrings muscle strength, gait velocity, and Knee Society score. Balance and posture control were assessed using the following computerized posturography tests: the weight bearing test, modified Clinical Test of Sensory Interaction on Balance (mCTSIB) test, and sit-to-stand test. Pre- and postoperative differences were analyzed using Wilcoxon and chi-square tests, and effect size was measured using standardized response mean. Correlations were assessed by the Spearman test. One year after TKA, some improvement in balance tests was observed. Significant differences were observed in the mCTSIB test: foam surface with open eyes (P≤.001), foam surface with closed eyes (P≤.001), and composite value (P≤.001). Effect size was moderate to high. Age showed significant correlation with mCTSIB composite value changes (-0.369; P=.037). No significant correlations were found between posturographic tests and other analyzed variables. Balance measured by computerized posturography improved 1 year after TKA. Significant changes were observed between open and closed eyes using a foam surface for the mCTSIB test. A mild negative correlation was found between age and posturographic changes.

    An intense tectonic activity in eastern Sicily and southern Calabria is well documented by the differential uplift of Late Quaternary coastlines and by the record of the strong historical earthquakes. The extensional belt that crosses this area is dominated by a well established WNW-ESE-oriented extensional direction. However, this area is largely lacking of any structural analysis able to define the tectonics at a more local scale. In the attempt to fill this gap of knowledge, we carried out a systematic analysis of extension joint sets. In fact, the systematic field collection of these extensional features, coupled with an appropriate inversion technique, allows to determine the characteristic of the causative tectonic stress field. Joints are defined as outcrop-scale mechanical discontinuities showing no evidence of shear motion and being originated as purely extensional fractures. Such tectonic features are one of the most common deformational structures in every tectonic environment and particularly abundant in the study area. A particular arrangement of joints, called "fracture grid-lock system", and defined as an orthogonal joint system where mutual abutting and crosscutting relationships characterize two geologically coeval joint sets, allow to infer the direction and the magnitude of the tectonic stress field. We performed the analyses of joints only on Pleistocene deposits of Eastern Sicily and Southern Calabria. Moreover we investigated only calcarenite sediments and cemented deposits, avoiding claysh and loose matrix-supported clastic sediments where the deformation is generally accomodated in a distributed way through the relative motion between the single particles. In the selection of the sites, we also took into account the possibility to clearly observe the geometric relationships among the joints. For this reason we chose curvilinear road cuts or cliffs, wide coastal erosional surfaces and quarries. The numerical inversions show a similar stress

    Papayas are one of the main fresh fruits in Taiwan area. Papaya fruits were treated with hot water to pasteurize peels followed by /sup 60/Co gamma-ray irradiation to extend the ripening time. The purpose of synergetic methods is to extend the shelf life of papaya fruits. This experiment was carried out by seven treatments, which were: (1) control group, (2) hot water treatment only, (3) hot water treatment with a 25 krad ..gamma..-irradiation, (4) hot water treatment with a 50 krad ..gamma..-irradiation, (5) hot water treatment with a 75 krad ..gamma..-irradiation, (6) 75 krad ..gamma..-irradiation only, and (7) hot water treatment with a 100 krad ..gamma..-irradiation. The items of observation were: surface yellowing, surface decaying, quality of texture, and length of period lasted after irradiation for 50% marketable papayas. The results of this study showed that a shelf-life extension of six days could be obtained for papayas subjected to hot water (50 to 55/sup 0/C) treatment and a 100 krad irradiation. 3 refs., 2 figs., 2 tabs.

  2. An Application Domain Extension to CityGML for immovable property taxation: A Turkish case study

    2013-04-01

    It is generally acknowledged that immovable property taxes are one of the main revenue sources for local government. The literature emphasizes that the administration of property taxes needs well-developed inventories or registers that provide complete and accurate records of the taxed properties and their legal-economic attributes. This requirement is generally fulfilled by Spatial Data Infrastructures (SDIs) in which the coordinate exchange and sharing of geo-spatial data is provided by separate registers/information systems such as: cadastral systems, building and address registers. Recently, the Open Geospatial Consortium presented a core component of a 3D SDI in the form of an international domain standard for representing, storing and exchanging 3D city models. The CityGML allows the semantic and 3D geometrical representation of physical objects but does not deal with the legal and administrative aspects of the city objects which are required for the process of property taxation. This paper outlines the development of an Application Domain Extension (ADE) for the immovable property taxation domain that expands the CityGML data model with the legal and administrative concepts defined in Turkish Law. The study shows that this ADE could be a 3D national data model for municipal information systems and facilitate a more efficient taxation process, as well as providing data for urban planning, facility management and other municipal services.

    Some researchers in the field of ageing claim that significant extension of the human lifespan will be possible in the near future. While many of these researchers have assumed that the community will welcome this technology, there has been very little research on community attitudes to life extension. This paper presents the results of an in-depth qualitative study of community attitudes to life extension across age groups and religious boundaries. There were 57 individual interviews, and 8 focus groups (totalling 72 focus group participants) conducted with community members in Brisbane, Australia. Community attitudes to life extension were more varied and complex than have been assumed by some biogerontologists and bioethicists. While some participants would welcome the opportunity to extend their lives others would not even entertain the possibility. This paper details these differences of opinion and reveals contrasting positions that reflect individualism or social concern among community members. The findings also highlight the relationship between Christianity, in particular belief in an afterlife, and attitudes to life extension technology. Overall, the study raises questions about the relationship between interest in life extension, the medicalisation of ageing and the increasing acceptability of enhancement technologies that need to be addressed in more representative samples of the community.

  5. Identifying the Functional Flexion-extension Axis of the Knee: An In-Vivo Kinematics Study.

    Directory of Open Access Journals (Sweden)

    Li Yin

    Full Text Available This study aimed to calculate the flexion-extension axis (FEA of the knee through in-vivo knee kinematics data, and then compare it with two major anatomical axes of the femoral condyles: the transepicondylar axis (TEA defined by connecting the medial sulcus and lateral prominence, and the cylinder axis (CA defined by connecting the centers of posterior condyles.The knee kinematics data of 20 healthy subjects were acquired under weight-bearing condition using bi-planar x-ray imaging and 3D-2D registration techniques. By tracking the vertical coordinate change of all points on the surface of femur during knee flexion, the FEA was determined as the line connecting the points with the least vertical shift in the medial and lateral condyles respectively. Angular deviation and distance among the TEA, CA and FEA were measured.The TEA-FEA angular deviation was significantly larger than that of the CA-FEA in 3D and transverse plane (3.45° vs. 1.98°, p < 0.001; 2.72° vs. 1.19°, p = 0.002, but not in the coronal plane (1.61° vs. 0.83°, p = 0.076. The TEA-FEA distance was significantly greater than that of the CA-FEA in the medial side (6.7 mm vs. 1.9 mm, p < 0.001, but not in the lateral side (3.2 mm vs. 2.0 mm, p = 0.16.The CA is closer to the FEA compared with the TEA; it can better serve as an anatomical surrogate for the functional knee axis.

    Our initiative aimed to produce recommendations on post-randomised controlled trial (RCT) trial extension studies (TES) reporting using European League Against Rheumatism (EULAR) standard operating procedures in order to achieve more meaningful output and standardisation of reports. We formed a task force of 22 participants comprising RCT experts, clinical epidemiologists and patient representatives. A two-stage Delphi survey was conducted to discuss the domains of evaluation of a TES and definitions. A '0-10' agreement scale assessed each domain and definition. The resulting set of recommendations was further refined and a final vote taken for task force acceptance. Seven key domains and individual components were evaluated and led to agreed recommendations including definition of a TES (100% agreement), minimal data necessary (100% agreement), method of data analysis (agreement mean (SD) scores ranging between 7.9 (0.84) and 9.0 (2.16)) and reporting of results as well as ethical issues. Key recommendations included reporting of absolute numbers at each stage from the RCT to TES with reasons given for drop-out at each stage, and inclusion of a flowchart detailing change in numbers at each stage and focus (mean (SD) agreement 9.9 (0.36)). A final vote accepted the set of recommendations. This EULAR task force provides recommendations for implementation in future TES to ensure a standardised approach to reporting. Use of this document should provide the rheumatology community with a more accurate and meaningful output from future TES, enabling better understanding and more confident application in clinical practice towards improving patient outcomes.

    Objectives Recent studies suggest that comprehensive smoking regulations to decrease exposure to second-hand smoke reduce the rates of acute myocardial infarction (AMI). The objective of this paper is to analyse if deaths due to AMI in Spain declined after smoking prevention legislation came into force in January 2006. Design Information was collected on deaths registered by the Instituto Nacional de Estadística for 2004–2007. Age- and sex-specific annual AMI mortality rates with 95% CIs were estimated, as well as age-adjusted annual AMI mortality rates by sex. Annual relative risks of death from AMI were estimated with an age-standardised Poisson regression model. Results Adjusted AMI mortality rates in 2004 and 2005 are similar, but in 2006 they show a 9% decline for men and a 8.7% decline for women, especially among those over 64 years of age. In 2007 there is a slower rate of decline, which reaches statistical significance for men (−4.8%) but not for women (−4%). The annual relative risk of AMI death decreased in both sexes (p<0.001) from 1 to 0.90 in 2006, and to 0.86 in 2007. Conclusion The extension of smoke-free regulations in Spain was associated with a reduction in AMI mortality, especially among the elderly. Although other factors may have played a role, this pattern suggests a likely influence of the reduction in population exposure to second-hand smoke on AMI deaths. PMID:22021746

    Background Implantable cardioverter defibrillator (ICD) implantation is contraindicated in those with <1 year life expectancy. Objective To develop a risk prediction score for 1-year mortality in patients with primary prevention ICDs and to determine the incremental improvement in discrimination when incorporating serum-based biomarkers to traditional clinical variables. Methods We analyzed data from the PROSE-ICD study, a large prospective observational study of patients undergoing primary prevention ICD implantation who were extensively phenotyped for clinical and serum markers. We identified variables predicting 1-year mortality and synthesized them into a comprehensive risk scoring construct using backward selection. Results Among 1,189 patients deemed by their treating physicians as having reasonable 1 year life expectancy, 62 patients died within 1 year of ICD implantation. The risk score, comprised of 6 clinical factors (age ≥75 years, New York Heart Association class III/IV, atrial fibrillation, eGFR <30mL/min/1.73m2, diabetes, and use of diuretics), had good discrimination (AUC=0.77) for 1-year mortality. Addition of 3 biomarkers (TNF-αRII, pro-BNP, and cTnT) further improved model discrimination to 0.82. Patients with 0-1, 2-3, 4-6, or 7-9 risk factors had 1-year mortality rates of 0.8%, 2.7%, 16.1% and 46.2%, respectively. Conclusions Individuals with more co-morbidities and elevations of specific serum biomarkers were at increased risk for all-cause mortality despite being deemed as having reasonable 1 year life expectancy. A simple risk score comprised of readily available clinical data and serum biomarkers may better identify patients at high risk of early mortality and improve patient selection and counseling for primary prevention ICD therapy.

    Mechanical analysis has the potential to provide complementary information to aneurysm morphology in assessing its vulnerability. Reliable calculations require accurate material properties of individual aneurysmal components. Quantification of extreme extensibility and ultimate material strength of the tissue are important if rupture is to be modelled. Tissue pieces from 11 abdomen aortic aneurysm (AAA) from patients scheduled for elective surgery and from 8 normal aortic artery (NAA) from patients who scheduled for kidney/liver transplant were collected at surgery and banked in liquid nitrogen with the use of Cryoprotectant solution to minimize frozen damage. Prior to testing, specimen were thawed and longitudinal and circumferential tissue strips were cut from each piece and adventitia, media and thrombus if presented were isolated for the material test. The incremental Young's modulus of adventitia of NAA was direction-dependent at low stretch levels, but not the media. Both adventitia and media had a similar extreme extensibility in the circumferential direction, but the adventitia was much stronger. For aneurysmal tissues, no significant differences were found when the incremental moduli of adventitia, media or thrombus in both directions were compared. Adventitia and media from AAA had similar extreme extensibility and ultimate strength in both directions and thrombus was the weakest material. Adventitia and media from AAA were less extensible compared with those of NAA, but the ultimate strength remained similar. The material properties, including extreme extensibility and ultimate strength, of both healthy aortic and aneurysmal tissues were layer-dependent, but not direction-dependent.

    To evaluate the effect of prophylactic cranial irradiation (PCI) on overall survival (OS) in patients with extensive small cell lung cancer (ESCLC). Between April 2005 and May 2014, 204 patients with ESCLC who had any response (according to RECIST 1.1) to initial chemotherapy were reviewed. All patients had undergone appropriate imaging tests to exclude brain metastases before initial chemotherapy. PCI was performed on 45 patients (22.1 %) and the remaining patients (77.9 %) received no such treatment (control group). Primary endpoint was OS. The incidence of brain metastases, brain metastases-free survival (BMFS), and adverse effects were also evaluated. Survival data of the 204 patients were analyzed statistically. PCI significantly prolonged median OS from 12.6 to 16.5 months as compared to the control group (hazard ratio, HR, 0.63; 95 % confidence interval, CI, 0.41 to 0.96; p = 0.033). PCI significantly lowered the risk of brain metastases (HR 0.48; 95 % CI 0.30 to 0.76; p = 0.001). The 1-year incidence of brain metastases was 17.1 and 55.9 % in the PCI and control group, respectively. PCI significantly correlated with the increased median BMFS (p = 0.002). Additionally, multivariate analyses demonstrated that PCI was a favorable independent predictor of OS, BMFS, and the incidence of brain metastases. Acute and chronic adverse effects were generally low grade and well tolerated in patients receiving PCI. PCI after any response to initial chemotherapy significantly improved OS of ESCLC patients analyzed in this study. (orig.)

  19. Applications of Extensive Green-roof Systems in Contributing to Sustainable Development in Densely Populated Cities: a Hong Kong Study

    Directory of Open Access Journals (Sweden)

    Xiaoling Zhang

    2011-03-01

    Full Text Available Developed cities such as Hong Kong are usually densely populated. Since the land is limited, high-rise buildings are constructed. When the building height becomes higher, air flow is reduced and heat is trapped among high-rise buildings. Air temperature will be greatly increased and air pollution becomes a serious problem. This creates a walled building problem. To reduce air temperature caused by the wall-effects, various methods have been developed in the previous studies. One typical method is the use of green roof systems. The application of extensive green roofs on the existing building rooftops has been recommended in Hong Kong since 2001. The advantage of this practice is that no additional floor area is required and it can also improve urban greenery. Although a green roof system has been introduced and adopted in Hong Kong since 2001, the emphasis is mainly given to the application of intensive green roofs for podium garden instead of extensive green roofs. It is considered valuable and necessary of the extensive green roofs for the buildings. This paper investigates the current practice of using extensive green roofs in Hong Kong. The constraints in applying extensive green roofs are investigated, which leads to studying the solutions for mitigating these constraints and improving the future development of the implementation.

    The importance of advanced e-beam writing system and chemically amplified resist (CAR) coated blank is increasing gradually in high-end grade photomask manufacture according to CD embodiment of 90 nm and beyond technology node requiring because of the shrinkage of design rule in the semiconductor industry. However, many studies have been reported that CAR has several troubles and especially, CAR sensitivity change is occurred by airborne molecular contamination (AMC). So, the storage life of CAR coated blank is shortened. This problem may cause the difficulty of high-end grade photomask manufacture because it is hard to secure stable mean to target (MTT) and CD uniformity by sensitivity change, T-top profile and footing profile. Therefore, the purpose of this paper is to investigate the storage life extension for high performance CAR coated blank through improvement of the packing materials. Firstly, a variety of packing materials were collected and the selected packing materials were analyzed by Automatic Thermal Desorption Gas Chromatograph/Mass Spectrometer (ATD GC/MS) and Ion Chromatograph (IC) to examine AMC generated from the packing materials. As a result, molecular condensables such as alcohols, hydrocarbons and fatty acids were detected and molecular acids and molecular bases those are NH4+, Cl-, NOx- and SOx- were also detected from the packing materials, respectively. From the above results, we selected the best packing materials which generated the least AMC and the worst packing materials which generated the most AMC. Additionally, we verified photomask process with CAR coated blanks which were packed with those packing materials with post coating delay (PCD) by 50 kV e-beam writing system. In consequence, dose to clear (DTC) showed 4.6 μC/cm2 at 0 day PCD for both of the best and the worst packing materials of CAR coated blank. After 90 days PCD, DTC variation was only 0.4 μC/cm2 for the best packing materials, but DTC variation of 4.0 μC/cm2

    To apply results of the hemocoagulation parameters to the DIC (disseminated intravascular coagulation) score system. Compare parameters of the DIC score in patients with extensive burn trauma (hospitalized at the Intensive Care Unit, ICU) and patients with lesser extent of burn injury (hospitalized at the standard unit). To use these data within the evidence based medicine for the prediction of organ damage and multi-organ failure. Prospective study. We have included total of 36 patients in the group within four months. Twelve patients were hospitalized at the ICU, 24 patients were hospitalized at the intermedial care and standard unit. Repeatedly, we have taken blood from patients to evaluate the hemocoagulation parameters. In patients hospitalized at the ICU, the blood was taken from the central vein (prior to the drawn, the access was flushed with 100 ml of F1/1, the blood was taken from different access than from the one administering heparin), in patients hospitalized at the standard unit the blood was taken from a peripheral vein. The results were then put into the tables established according to the ISTH (International Society on Thrombosis and Hemostasis). Next, the DIC score was calculated to predict severity of hemocoagulation balance disorders in burn trauma, or occurrence of complications during the treatment. Part 1: We have evaluated 12 patients (4 females) hospitalized at the ICU. At the day of injury the overt DIC score reached 1.25 (0-3), fifth day after the injury the average value of overt DIC score was 1.83 (0-3), one day after the autotransplantation it was 2.08 (0-3) and at the day of discharge from the hospital 0. In the deceased patient the DIC score reached value of 2. Part 2: We evaluated 24 patients (10 females) hospitalized at the standard unit. The extent of their burn injury was 5.9% TBSA (0.5-12% TBSA), age 49.13 years (17-94 years). At the day of injury the overt DIC score reached 0.25 (0-2). Fifth day after the injury the average

    It was found that for identical increases in bending moment, a winglet provides a greater gain in induced efficiency than a tip extension. Winglet toe-in angle allows design trades between efficiency and root moment. A winglet showed the greatest benefit when the wing loads were heavy near the tip. Washout diminished the benefit of either tip modification, and the gain in induced efficiency became a function of lift coefficient; heavy wing loadings obtained the greatest benefit from a winglet, and low speed performance was enhanced even more than cruise performance. Both induced efficiency and bending moment increased with winglet length and outward cant. The benefit of a winglet relative to a tip extension was greatest for a nearly vertical winglet. Root bending moment was proportional to the minimum weight of bending material required in the wing; it is a valid index of the impact of tip modifications on a new wing design.

    The paper presents anatomical considerations on the abnormal ossification, which occurred around the dorsum of the sella turcica in the human skull of the female individual. Probably the morphological alterations of the sellar region were associated with extensive heterotopic ossification of the dura mater attached to the dorsum of the sella turcica and the posterior clinoid processes. The analysis of gray values of the voxels representing the areas of abnormal ossification indicated on variation in bone density in the entire sample. We have established that the highest mineralisation of bony tissue occurred in the marginal parts of the osseous extensions deriving from the posterior clinoid processes. The ossified parts of dura mater attached to the posterior clinoid processes showed significantly higher content of the hydroxyapatite (1.9 g/cm3) than the dorsum of the sella turcica (1.0 g/cm3).

    The purpose of our experiment was to test event-related potentials (ERP) accompanying the process of brand extension evaluation in people speaking Indo-European languages. The experimental procedure consisted of sequential presentations of pairs of stimuli; namely, a beverage brand name and a product name. The products fell into the category of beverages (congruent trials) or clothes (incongruent trials). In the response condition (RC), the participants decided whether they accepted the product as an extension of the brand. In the no-response condition (NRC), the participants' task was to attend the stimuli and try to remember them. In the response condition, the amplitudes of the N270, P300 and N400 components were sensitive to incongruence between the product category and the previously presented brand. However, in the no-response condition, differences emerged only at the level of early P1 and P2 components. Our results suggest that, in people speaking one of the Indo-European languages, the process of categorisation in brand extension evaluation is not automatic. Copyright © 2016 Elsevier Ireland Ltd.

    This study measured the concentrations of particulates and metallic elements in ambient air by using PS-1 sampler (TSP) at Longjing area. And this study focuses on the collection of ambient air particulates, metallic elements, particulate-bound mercury Hg(p), concentrations. In addition, the sources of ambient pollutants by way of back trajectory analysis are found. Moreover, test mean concentration variance differences for metallic elements (PM, Hg(p), Mn, Fe, Zn, Cr, Cu, and Pb) among the four seasons (spring, summer, autumn and winter) through ANOVA are calculated. The result indicates that the average highest particulate concentration occurred in winter season, and the order was winter > spring > autumn > summer, and the mostly highest average metallic element (Mn, Fe, Zn, Cr, Cu, Pb) concentrations occurred in autumn. Moreover, the mostly average lowest metallic element concentrations occurred in summer. In addition, the above results of backward trajectories that the major particulate pollutants parcel mainly come from northeastern Taiwan. Moreover, when comparing the results of the first half year to that of the second half year, the they indicated that all metallic elements displayed significant differences in concentrations except those of Hg(p), Mn, Fe, Zn. Finally, metallic element Hg(p) is the only one which showed no significant concentration difference from either seasonal variations or half-year observations.

    Whether self-reporting and clinician-rated depression scales correlate well with one another when applied to older adults has not been well studied, particularly among Asian samples. This study aimed to compare the level of agreement among measurements used in assessing major depressive disorder (MDD) among the Thai elderly and the factors associated with the differences found. This was a prospective, follow-up study of elderly patients diagnosed with MDD and receiving treatment in Thailand. The Mini International Neuropsychiatric Inventory (MINI), 17-item Hamilton Depression Rating Scale (HAMD-17), 30-item Geriatric Depression Scale (GDS-30), 32-item Inventory of Interpersonal Problems scale, Revised Experience of Close Relationships scale, ten-item Perceived Stress Scale (PSS-10), and Multidimensional Scale of Perceived Social Support were used. Follow-up assessments were conducted after 3, 6, 9, and 12 months. Among the 74 patients, the mean age was 68±6.02 years, and 86% had MDD. Regarding the level of agreement found between GDS-30 and MINI, Kappa ranged between 0.17 and 0.55, while for Gwet's AC1 the range was 0.49 to 0.91. The level of agreement was found to be lowest at baseline, and increased during follow-up visits. The correlation between HAMD-17 and GDS-30 scores was 0.17 (P=0.16) at baseline, then 0.36 to 0.41 in later visits (P<0.01). The PSS-10 score was found to be positively correlated with GDS-30 at baseline, and predicted the level of disagreement found between the clinicians and patients when reporting on MDD. The level of agreement between the GDS, MINI, and HAMD was found to be different at baseline when compared to later assessments. Patients who produced a low GDS score were given a high rating by the clinicians. An additional self-reporting tool such as the PSS-10 could, therefore, be used in such under-reporting circumstances.

    To determine the prevalence of otitis media with effusion in children younger than 1 year and its association with the season of the year, artificial feeding, environmental and perinatal factors. Retrospective study of 184 randomly included medical records from a total of 982 healthy infants evaluated for hearing screening tests. Diagnosis of otitis media with effusion was based on otoscopy (amber-gold color, fluid level, handle of malleus position), type B tympanometric curves and absence of otoacoustic emissions. Incomplete medical records or those describing acute otitis media, upper respiratory tract infections on the assessment day or in the last 3 months, neuropathies and craniofacial anomalies were excluded. Data such as gestational age, birth weight, Apgar score, type of feeding and day care attendance were compared between children with and without otitis media with effusion through likelihood tests and multivariate analysis. 25.3% of 184 infants had otitis media with bilateral effusion; 9.2% had unilateral. In infants with otitis media, the following were observed: chronological age of 9.6±1.7 months; gestational age >38 weeks in 43.4% and birth weight >2,500g in 48.4%. Otitis media with effusion was associated with winter/fall, artificial feeding, Apgar score otitis media with effusion. Otitis media with effusion was found in about one third of children younger than 1 year and was mainly associated with artificial feeding. Copyright © 2015 Sociedade de Pediatria de São Paulo.

    The purpose of this study was to quantify changes in volumetric bone mineral density (vBMD) in the tibial plateau of the operated and contralateral leg measured using peripheral quantitative computed tomography (pQCT) before and 3, 6, and 12 months after anterior cruciate ligament (ACL) reconstruction. The ACL was reconstructed with a hamstring tendon autograft using press-fit fixation. pQCT measurements of the proximal tibia were obtained in 61 patients after ACL reconstruction, and total, cortical, and trabecular vBMD were calculated. vBMD in the operated leg decreased from baseline to 3 months (-12% [total], -11% [cortical], and -12.6% [trabecular]; preconstruction contributed to loss in bone mineral density within the first year after surgery. The role of factors such as time of weight-bearing, joint mechanics, post-traumatic inflammatory reactions, or genetic predisposition in modulating the development of posttraumatic knee osteoarthritis after ACL injury should be further elucidated.

    This report describes the 12-month outcomes of the a prospective, multicenter, nonrandomized post-approval study of the MitraClip therapy in Europe (ACCESS-EU postapproval study of MitraClip therapy) with respect to preprocedural left ventricular ejection fraction (LVEF). Transcatheter deployment of the MitraClip device may be considered for patients who are not suitable for conventional surgery. A total of 567 patients with significant mitral regurgitation (MR) underwent MitraClip therapy. Of those, 393 had functional MR (FMR) and were subdivided by preprocedural LVEF (A: 10% to 20%, B: >20% to 30%, C: >30% to 40%, D: >40%). Procedural safety and efficacy and treatment outcomes including MR grade, New York Heart Association (NYHA) functional class, 6-minute walk test, and the Minnesota Living with Heart Failure Questionnaire were analyzed at baseline, 30 days, and 12 months. Baseline mean logistic EuroSCORE was 25 ± 19; 87% of patients were in NYHA classes III or IV (A: 96%, B: 83%, C: 90%, D: 86%). There was no incidence of death or stroke intraprocedurally. Eleven patients died within 30 days with no differences among subgroups. Kaplan-Meier survival at 12 months was 81.8% (A: 71%, B: 79%, C: 87%, D: 86%). There was a significant improvement in MR severity at 30 days and 12 months (p FMR. In conclusion, the low rates of hospital mortality and adverse events in patients with FMR-even in patients with severely reduced LVEF-provide additional evidence of substantial benefits after MitraClip implantation.

    Increasing HIV testing among men who have sex with men (MSM) is a major policy goal in the UK. Social marketing is a common intervention to increase testing uptake. We used an online panel of MSM to examine rates of HIV testing behaviour and the impact of a social marketing intervention on them. MSM in England were recruited to a longitudinal internet panel through community websites and a previous survey. Following an enrolment survey, respondents were invited to self-complete 13 surveys at monthly intervals throughout 2011. A unique alphanumeric code linked surveys for individuals. Rates of HIV testing were compared relative to prompted recognition of a multi-part media campaign aiming to normalise HIV testing. Of 3386 unique enrolments, 2047 respondents were included in the analysis, between them submitting 15,353 monthly surveys (equivalent to 1279 years of follow-up), and recording 1517 HIV tests taken, giving an annual rate of tests per participant of 1.19 (95% CI 1.13 to 1.25). Tests were highly clustered in individuals (61% reported no test during the study). Testing rates were higher in London, single men and those aged 25-34 years. Only 7.6% recognised the intervention when prompted. After controlling for sociodemographic characteristics and exposure to other health promotion campaigns, intervention recognition was not associated with increased likelihood of testing. Higher rates of testing were strongly associated with higher number of casual sexual partners and how recently men had HIV tested before study enrolment. This social marketing intervention was not associated with increased rates of HIV testing. More effective promotion of HIV testing is needed among MSM in England to reduce the average duration of undiagnosed infection. Published by the BMJ Publishing Group Limited.

    Cosmic rays with energy exceeding ~ 10^{18} eV are referred to as ultra-high energy cosmic rays (UHECRs). Monte Carlo codes for extensive air shower (EAS) simulate the development of EASs initiated by UHECRs in the Earth's atmosphere. Experiments to detect UHECRs utilize EAS simulations to estimate their energy, arrival direction, and composition. In this paper, we compare EAS simulations with two different codes, CORSIKA and COSMOS, presenting quantities including the longitudinal distribution of particles, depth of shower maximum, kinetic energy distribution of particle at the ground, and energy deposited to the air. We then discuss implications of our results to UHECR experiments.

    1989-01-01

    Twelve patients were followed for 5 years after treatment with a 12-unit cantilever fixed partial denture on the mandibular canines opposed by a complete maxillary denture. Two fixed dentures had to be removed, one because of an abutment tooth root-fracture and one because of rapid marginal bone loss in a terminal stage of leukemia. Caries and periodontal lesions were rare, but other complications, principally related to endodontics, occurred. All complications were amenable to standard treatment procedures. Extensive mandibular cantilever fixed partial dentures may be used in the rehabilitation of patients with a very reduced dentition and a history of difficulties in adapting to removable dentures.

    The concept of Tsallis entropy provides an extension of thermodynamics and statistical physics. In the ecology, Tsallis entropy is proposed to be a new class of diversity indices Sq which covers many common diversity indices found in ecological literature. As a new statistical model for the Whittaker plots describing species abundance distribution, the truncated exponential distribution is used to calculate the diversity and evenness indices. The obtained results in new model are graphically compared with those in previous publication in the same field of interests, and shows a good agreement. A further development of a thermodynamic theory of ecological systems that is consistent with entropic approach of statistical physics is motivated.

    A case of glomus jugulare tumor with intra- and extracranial extension is described. The patient was a 63-year-old woman who complained of gait and memory disturbances. On admission neurological examination revealed recent memory disturbance, left deafness, left XI, XIIth cranial nerve palsies, and slight ataxic gait. Roentgenogram of the skull showed an enlarged left jugular foramen with bone erosion. Plain X-ray computerized tomography scan (X-CT) indicated obstructive hydrocephalus and X-CT with contrast enhancement revealed a mass lesion in the left posterior cranial fossa extending through enlarged left jugular foramen to the extracranial space toward the level of C/sub 2/. Cerebral angiography demonstrated a large mass with blood supply from branches of left external carotid and vertebral arteries. The tumor stain was not remarkable. Left internal jugular vein was completely obstructed at the level of the second cervical vertebral body. Magnetic resonance imaging (MRI) clearly showed the tumor extending from the anterolateral portion to the second cervical vertebral body through the enlarged jugular foramen to the posterior cranial fossa. Brain stem and cerebellar hemisphere which were markedly compressed by the mass were clearly visualized. At first a ventriculo-peritoneal shunt was made and four weeks later subtotal removal of the tumor was undertaken. Histopathology of tumor specimen showed typical glomus jugulare tumor. MRI was considered to be very useful for the diagnosis and treatment of the glomus jugulare tumor with intra- and extracranial extension

    Martínez, O.; Pérez, E.; Salazar, H.; Villaseñor, L.

    We describe the design of an extensive air shower detector array built in the Campus of the University of Puebla (located at 19°N, 90°W, 800 gcm -2) to measure the energy and arrival direction of primary cosmic rays with energies around 1015 eV. The array consists of 18 liquid scintillator detectors (12 in the first stage) and 6 water Cherenkov detectors (one of 10 m 2 cross section and five smaller ones of 1.86 m 2 cross section), distributed in a square grid with a detector spacing of 20 m over an area of 4000 m 2. In this paper we discuss the calibration and stability of the array, and discuss the capability of hybrid arrays, such as this one consisting of water Cherenkov and liquid scintillator detectors, to allow a separation of the electromagnetic and muon components of extensive air showers. This separation plays an important role in the determination of the mass and identity of the primary cosmic ray. This facility is also used to train students interested in the field of cosmic rays.

    Agricultural and extension education--or some derivative name--is a field of study leading to the doctoral degree in universities around the world. Is there are body of knowledge or a taxonomy of the knowledge--e.g., a knowledge domain--that one should possess with a doctorate in agricultural and extension education? The purpose of this paper was to synthesize the work of researchers who attempted to define the field of study, with a taxonomy comprising the knowledge domains (standards) and knowledge objects--structured interrelated sets of data, knowledge, and wisdom--of the field of study. Doctoral study in agricultural and extension education needs a document that provides for rules and guidelines--rules and guidelines that in turn provide for common and repeated use--all leading to achievement of an optimum degree of order in the context of academic, scholarly, and professional practice in agricultural and extension education. Thus, one would know in broad categories the knowledge, skills, and abilities possessed by one who holds a doctoral degree in agricultural and extension education. That is, there would exist a standard for doctoral degrees in agricultural and extension education. A content analysis of three previous attempts to categorize knowledge in agricultural and extension education served as the primary technique to create a new taxonomy--or to confirm an existing taxonomy--for doctoral study in agricultural and extension education. The following coalesced as nine essential knowledge domains for a doctorate in agricultural and extension education: (1) history, philosophy, ethics, and policy; (2) agricultural/rural development; (3) organizational development and change management; (4) planning, needs assessment, and evaluation; (5) learning theory; (6) curriculum development and instructional design; (7) teaching methods and delivery strategies; (8) research methods and tools; and, (9) scholarship and communications.

    Nesterov's accelerated gradient methods (AGM) have been successfully applied in many machine learning areas. However, their empirical performance on training max-margin models has been inferior to existing specialized solvers. In this paper, we first extend AGM to strongly convex and composite objective functions with Bregman style prox-functions. Our unifying framework covers both the $\\infty$-memory and 1-memory styles of AGM, tunes the Lipschiz constant adaptively, and bounds the duality gap. Then we demonstrate various ways to apply this framework of methods to a wide range of machine learning problems. Emphasis will be given on their rate of convergence and how to efficiently compute the gradient and optimize the models. The experimental results show that with our extensions AGM outperforms state-of-the-art solvers on max-margin models.

    The identification and purification of molecules active in promoting neurite outgrowth requires a sensitive reproducible bioassay. A quantitative bioassay was utilized to purify a neurite extension factor (NEF) based on counting the number of phase bright neurons with processes at least equal to one cell body diameter after 20 hrs. in culture is defined, serum free medium. Using a combination of heat treatment DEAE cellulose chromatography and gel filtration, an acidic protein of M sub r = 75,000 was highly purified. Upon reduction, it yields subunits of M sub r = 37,000. Purified fractions are active half maximally at 100 ng/ml in inducing neurite outgrowth in this bioassay. Currently, monoclonal antibodies to NEF are being produced. Female Balb C mice were immunized with the antigen and fusions with mouse myeloma cells will be performed to yield hybridoma cells.

    Full Text Available The way to improve the performance of the throughput in the wireless Mesh network is nodes with multiple interfaces. In view of the problem of multi-interface multi-channel extension for OLSR protocol, multi–interface multi-channel OLSR protocol is proposed. Nodes can have multiple network interfaces, but each node has only one IP, using the index of interface to distinguish the multiple interfaces of the node. Selected the receiving interface according to the channel, modified the message delivery method and introduces the protocol implementation and technology. Finally, the simulation is carried out by using the extended NS2. Simulation results show that extended OLSR protocol has high network performance, and improve the network throughput. What is new and original in this paper is adding multiple physical interface support for proactive protocol OLSR.

    Highlights: Black-Right-Pointing-Pointer EcDHODH is a membrane-associated enzyme and a promising target for drug design. Black-Right-Pointing-Pointer Enzyme's N-terminal extension is responsible for membrane association. Black-Right-Pointing-Pointer N-terminal works as a molecular lid regulating access to the protein interior. -- Abstract: Dihydroorotate dehydrogenases (DHODHs) are enzymes that catalyze the fourth step of the de novo synthesis of pyrimidine nucleotides. In this reaction, DHODH converts dihydroorotate to orotate, using a flavine mononucleotide as a cofactor. Since the synthesis of nucleotides has different pathways in mammals as compared to parasites, DHODH has gained much attention as a promising target for drug design. Escherichia coli DHODH (EcDHODH) is a family 2 DHODH that interacts with cell membranes in order to promote catalysis. The membrane association is supposedly made via an extension found in the enzyme's N-terminal. In the present work, we used site directed spin labeling (SDSL) to specifically place a magnetic probe at positions 2, 5, 19, and 21 within the N-terminal and thus monitor, by using Electron Spin Resonance (ESR), dynamics and structural changes in this region in the presence of a membrane model system. Overall, our ESR spectra show that the N-terminal indeed binds to membranes and that it experiences a somewhat high flexibility that could be related to the role of this region as a molecular lid controlling the entrance of the enzyme's active site and thus allowing the enzyme to give access to quinones that are dispersed in the membrane and that are necessary for the catalysis.

    Q fever, a worldwide zoonotic disease caused by Coxiella burnetii, is endemic in northern Spain where it has been reported as responsible for large series of human pneumonia cases and domestic ruminants' reproductive disorders. To investigate pathogen exposure among domestic ruminants in semi-extensive grazing systems in northern Spain, a serosurvey was carried out in 1,379 sheep (42 flocks), 626 beef cattle (46 herds) and 115 goats (11 herds). Serum antibodies were analysed by ELISA and positive samples were retested by Complement Fixation test (CFT) to detect recent infections. ELISA anti-C. burnetii antibody prevalence was slightly higher in sheep (11.8 +/- 2.0%) than in goats (8.7 +/- 5.9%) and beef cattle (6.7 +/- 2.0%). Herd prevalence was 74% for ovine, 45% for goat and 43% for bovine. Twenty-one percent of sheep flocks, 27% of goat and 14% of cattle herds had a C. burnetii seroprevalence >or= 20%. Only 15 out of 214 ELISA-positive animals reacted positive by CFT. Age-associated seroprevalence differed between ruminant species with a general increasing pattern with age. No evidence of correlation between abortion history and seroprevalence rates was observed despite the known abortifacient nature of C. burnetii in domestic ruminants. Results reported herein showed that sheep had the highest contact rate with C. burnetii in the region but also that cattle and goats should not be neglected as part of the domestic cycle of C. burnetii. This work reports basic epidemiologic patterns of C. burnetii in semi-extensive grazed domestic ruminants which, together with the relevant role of C. burnetii as a zoonotic and abortifacient agent, makes these results to concern both Public and Animal Health Authorities.

    Ethiopia is one of the sub-Saharan countries most affected by high disease burden, aggravated by a shortage and imbalance of human resources, geographical distance, and socioeconomic factors. In 2004, the government introduced the Health Extension Program (HEP), a primary care delivery strategy, to address the challenges and achieve the World Health Organization Millennium Development Goals (MDGs) within a context of limited resources. The health system was reformed to create a platform for integration and institutionalization of the HEP with appropriate human capacity, infrastructure, and management structures. Human resources were developed through training of female health workers recruited from their prospective villages, designed to limit the high staff turnover and address gender, social and cultural factors in order to provide services acceptable to each community. The service delivery modalities include household, community and health facility care. Thus, the most basic health post infrastructure, designed to rapidly and cost-effectively scale up HEP, was built in each village. In line with the country's decentralized management system, the HEP service delivery is under the jurisdiction of the district authorities. The nationwide implementation of HEP progressed in line with its target goals. In all, 40 training institutions were established, and over 30,000 Health Extension Workers have been trained and deployed to approximately 15,000 villages. The potential health service coverage reached 92.1% in 2011, up from 64% in 2004. While most health indicators have improved, performance in skilled delivery and postnatal care has not been satisfactory. While HEP is considered the most important institutional framework for achieving the health MDGs in Ethiopia, quality of service, utilization rate, access and referral linkage to emergency obstetric care, management, and evaluation of the program are the key challenges that need immediate attention.

  18. Study of Thorium-Plutonium Fuel for Possible Operating Cycle Extension in PWRs

    Directory of Open Access Journals (Sweden)

    Klara Insulander Björk

    2013-01-01

    Full Text Available Computer simulations have been carried out to investigate the possibility of extending operating cycle length in the Pressurised Water Reactor Ringhals 3 by the use of thorium-plutonium oxide fuel. The calculations have been carried out using tools and methods that are normally employed for reload design and safety evaluation in Ringhals 3. The 3-batch reload scheme and the power level have been kept unchanged, and a normal uranium oxide fuel assembly designed for a 12-month operating cycle in this reactor is used as a reference. The use of plutonium as the fissile component reduces the worth of control rods and soluble boron, which makes it necessary to modify the control systems. The delayed neutron fraction is low compared with the reference, but simulations and qualitative assessments of relevant transients indicate that the reactor could still be operated safely. Differences in reactivity coefficients are mainly beneficial for the outcome of transient simulations for the thorium based fuel. A 50% extension of the current 12-month operating cycle length should be possible with thorium-plutonium mixed oxide fuel, given an upgrade of the control systems. More detailed simulations have to be carried out for some transients in order to confirm the qualitative reasoning presented.

    2017-07-01

    In this paper, a tunneling graphene nanoribbon field effect transistor with electrically activated drain extension, namely, EA-T-GNRFET, is proposed. The proposed structure includes a side gate at the drain side with a constant voltage and length of 0.4 V and 15 nm, respectively. Simulations are performed based on the non-equilibrium Green's function method coupled with the Poisson equation in the mode space representation. This side gate creates an additional step in potential profile at the drain side, which increases and decreases the width of tunneling barrier and leakage current, respectively. Furthermore, the proposed structure has lower drain induced barrier thinning, lower sub-threshold swing (SS) and higher I ON/I OFF ratio than the conventional structure. Also, other characteristics of the device such as switching delay ( τ ), power delay product (PDP) and unity-gain frequency (f t) are improved in the proposed device. These advantages make EA-T-GNRFET more suitable for digital and analog applications.

    OBJECTIVES: An earlier report described desirable 1-month follow-up effects of the Safe Dates program on psychological, physical, and sexual dating violence. Mediators of the program-behavior relationship also were identified. The present report describes the 1-year follow-up effects of the Safe Dates program. METHODS: Fourteen schools were in the randomized experiment. Data were gathered by questionnaires in schools before program activities and 1 year after the program ended. RESULTS: The short-term behavioral effects had disappeared at 1 year, but effects on mediating variables such as dating violence norms, conflict management skills, and awareness of community services for dating violence were maintained. CONCLUSIONS: The findings are considered in the context of why program effects might have decayed and the possible role of boosters for effect maintenance. PMID:11029999

    In this work, an electron which is strongly coupled to the LO-phonon in triangular quantum dots with Coulomb impurity is considered. The eigenenergies and eigenfunctions of the ground and the first-excited states of the electron are obtained using the Pekar variational method. We have studied decoherence of RbCl quantum dot qubit using the non-extensive entropy (Tsallis entropy) for different values of Coulomb impurity parameter, polaronic radius and electron-LO phonon coupling strength. Numerical analysis shows that the entropy has the oscillatory periodic evolution as function of the time due to the triangular form of the confinement. It is found that entropy oscillates under a standing wave envelope with increasing the Coulomb impurity parameter, electron-LO phonon coupling strength and polaronic radius. With reducing the non-extensive parameter q, the entropy increases and thereby we can miss information about the system.

    Full Text Available Nµ/Ne, muon to electron population ratio in extensive air showers at high altitudes has been shown to be a suitable estimator of primary cosmic rays mass composition. This study is based on simulated extensive air showers. The Nµ/Ne ratio has been obtained in 100 depths from the top of the atmosphere to the sea level for different primary particle masses and energies. An empirical relation between cosmic ray atomic mass and Nµ/Ne has been obtained. The relation has then been used for estimation of atomic masses of progenitors of another set of simulated showers. Although the estimated masses are rough, the accuracy of the estimation improves with observation altitude.

    Full Text Available The study aims to verify whether extensive reading (ER is able to promote senior high school students’ English reading motivation and foster positive attitude towards reading in English. It further explores the teachers’ perceptions of and the challenges faced in the implementation of ER activities. An ER activity was held for 12 weeks with 258 participants from 4 senior high schools in Southern Taiwan. Focus group interviews were then carried out with 72 randomly selected participants, after which individual interviews were conducted with 6 English teachers from these participating schools. Findings reveal that despite the challenges encountered in implementing the activity, the English teachers observed its benefits and were willing to encourage students to read extensively. The majority of the student participants also held positive attitudes towards the ER activity. Their positive attitudes, however, did not lead to the enhancement of their motivation in reading extensively due to the heavy workload from tests, homework or cram school. It was generally agreed that ER was time-consuming and not efficient enough to boost their exam scores. Accordingly, the study suggests that coordinated efforts and change of attitudes among the stakeholders are indispensable in the promotion of ER among senior high school students.

    The effect of bystander interventions on long-term functional outcomes among survivors of out-of-hospital cardiac arrest has not been extensively studied. We linked nationwide data on out-of-hospital cardiac arrests in Denmark to functional outcome data and reported the 1-year risks of anoxic brain damage or nursing home admission and of death from any cause among patients who survived to day 30 after an out-of-hospital cardiac arrest. We analyzed risks according to whether bystander cardiopulmonary resuscitation (CPR) or defibrillation was performed and evaluated temporal changes in bystander interventions and outcomes. Among the 2855 patients who were 30-day survivors of an out-of-hospital cardiac arrest during the period from 2001 through 2012, a total of 10.5% had brain damage or were admitted to a nursing home and 9.7% died during the 1-year follow-up period. During the study period, among the 2084 patients who had cardiac arrests that were not witnessed by emergency medical services (EMS) personnel, the rate of bystander CPR increased from 66.7% to 80.6% (Pbystander defibrillation increased from 2.1% to 16.8% (Pbystander CPR was associated with a risk of brain damage or nursing home admission that was significantly lower than that associated with no bystander resuscitation (hazard ratio, 0.62; 95% confidence interval [CI], 0.47 to 0.82), as well as a lower risk of death from any cause (hazard ratio, 0.70; 95% CI, 0.50 to 0.99) and a lower risk of the composite end point of brain damage, nursing home admission, or death (hazard ratio, 0.67; 95% CI, 0.53 to 0.84). The risks of these outcomes were even lower among patients who received bystander defibrillation as compared with no bystander resuscitation. In our study, we found that bystander CPR and defibrillation were associated with risks of brain damage or nursing home admission and of death from any cause that were significantly lower than those associated with no bystander resuscitation.

    Although proteomics studies the global expression of proteins, metabolomics characterizes and quantifies their end products: the metabolites, produced by an organism under a certain set of conditions. From this perspective it is apparent that proteomics and metabolomics are complementary and when joined allow a fuller appreciation of an organism's phenotype. Our studies using (1)H-nuclear magnetic resonance spectroscopic analysis showed the presence of glucose, amino acids, and trichloroacetic acid cycle metabolites in the urine after 48 hours of cisplatin administration. These metabolic alterations precede changes in serum creatinine. Biochemical studies confirmed the presence of glucosuria, but also showed the accumulation of nonesterified fatty acids, and triglycerides in serum, urine, and kidney tissue, despite increased levels of plasma insulin. These metabolic alterations were ameliorated by the use of fibrates. We propose that the injury-induced metabolic profile may be used as a biomarker of cisplatin-induced nephrotoxicity. These studies serve to illustrate that metabolomic studies add insight into pathophysiology not provided by proteomic analysis alone.

    Inadequate informatical support of multi-centre clinical trials lead to pure quality. In order to support a multi-centre clinical trial a data collection via WWW and Internet based on Java has been developed. In this study a generalization and extension of this prototype has been performed. The prototype has been applied to another clinical trial and a knowledge server based on C+t has been integrated via CORBA. The investigation and implementation of security aspects of web-based data collection is now under evaluation.

    We present results on the reconstructed image resolution of a position sensitive radiation instrument (COCAE) based on extensive simulation studies. The reconstructed image resolution has been investigated in a wide range of incident photon energies emitted by point-like sources located at different source-to-detector distances on and off the detector's symmetry axis. The ability of the detector to distinguish multiple radioactive sources observed simultaneously is investigating by simulating point-like sources of different energies located on and off the detector's symmetry axis and at different positions

    The Thermo Scientific™ SureTect™ Listeria species assay is a new real-time PCR assay for the detection of all species of Listeria in food and environmental samples. The assay was originally certified as Performance Tested Methods(SM) (PTM) 071304 in 2013. This report details the method modification study undertaken to extend the performance claims of the assay for matrixes of raw ground turkey, raw ground pork, bagged lettuce, raw pork sausages, pasteurized 2% fat milk, raw cod, pasteurized brie cheese, and ice cream. The method modification study was conducted using the AOAC Research Institute (RI) PTM program to validate the SureTect PCR assay in comparison to the reference method detailed in ISO 11290-1:1996 including amendment 1:2004. All matrixes were tested by Thermo Fisher Scientific (Basingstoke, United Kingdom). In addition, three matrixes (raw cod, bagged lettuce, and pasteurized brie cheese) were analyzed independently as part of the AOAC RI-controlled independent laboratory study by the University of Guelph, Canada. Using probability of detection statistical analysis, there was no significant difference in the performance between the SureTect assay and the International Organization for Standardization reference method for any of the matrixes analyzed in this study.

    In this paper, we propose a model in studying soft ferromagnetic films, which is readily accessible experimentally. By using penalty approximation and compensated compactness, we prove that the dynamical equation in thin film has a local weak solution. Moreover, the corresponding linear equation is also dealt with in great detail.

  15. What reassurances do the community need regarding life extension? Evidence from studies of community attitudes and an analysis of film portrayals.

    Science.gov (United States)

    Underwood, Mair

    2014-04-01

    It is increasingly recognized that community attitudes impact on the research trajectory, entry, and reception of new biotechnologies. Yet biogerontologists have generally been dismissive of public concerns about life extension. There is some evidence that biogerontological research agendas have not been communicated effectively, with studies finding that most community members have little or no knowledge of life extension research. In the absence of knowledge, community members' attitudes may well be shaped by issues raised in popular portrayals of life extension (e.g., in movies). To investigate how popular portrayals of life extension may influence community attitudes, I conducted an analysis of 19 films depicting human life extension across different genres. I focussed on how the pursuit of life extension was depicted, how life extension was achieved, the levels of interest in life extension shown by characters in the films, and the experiences of extended life depicted both at an individual and societal level. This paper compares the results of this analysis with the literature on community attitudes to life extension and makes recommendations about the issues in which the public may require reassurance if they are to support and accept life extension technologies.

  16. Offshore Extension of Deccan Traps in Kachchh, Central Western India: Implications for Geological Sequestration Studies

    The Deccan basalts in central western India are believed to occupy large onshore-offshore area. Using geophysical and geological observations, onshore sub-surface structural information has been widely reported. On the contrary, information about offshore structural variations has been inadequate due to scarcity of marine geophysical data and lack of onshore-offshore lithological correlations. Till date, merely a few geophysical studies are reported that gauge about the offshore extent of Deccan Traps and the Mesozoic sediments (pre-Deccan). To fill this gap in knowledge, in this article, we present new geophysical evidences to demonstrate offshore continuation of the Deccan volcanics and the Mesozoic sediments. The offshore multi-channel seismic and onshore-offshore lithological correlations presented here confirm that the Mesozoic sedimentary column in this region is overlain by 0.2-1.2-km-thick basaltic cover. Two separate phases of Mesozoic sedimentation, having very distinctive physical and lithological characteristics, are observed between overlying basaltic rocks and underlying Precambrian basement. Using onshore-offshore seismic and borehole data this study provides new insight into the extent of the Deccan basalts and the sub-basalt structures. This study brings out a much clearer picture than that was hitherto available about the offshore continuation of the Deccan Traps and the Mesozoic sediments of Kachchh. Further, its implications in identifying long-term storage of anthropogenic CO{sub 2} within sub-basalt targets are discussed. The carbon sequestration potential has been explored through the geological assessment in terms of the thickness of the strata as well as lithology.

    Low background experiments need active muon veto detectors to shield them from cosmic muons. Plastic scintillator panels with WLS fiber and multi-pixel Geiger-mode avalanche photodiodes readout are widely used in such experiments due to their compactness and robustness. In this paper, results from the study of the basic MRS APD parameters, such as breakdown voltages, quenching resistors, internal gain and dark count rates are presented, as well as temperature dependencies of some of these parameters. In a small fraction of the MRS APDs, some strange dips in the I-V curves just preceding the breakdown voltage point have been observed.

    2015-12-01

    Full Text Available Cross-coupling reactions between 2-methyl-2-propen-1-ol and various boronic acids are used to obtain aromatic-(2-methylallyl derivatives. However, deboronation or isomerization side reactions may occur for several boronic acids. We describe herein the synthesis of original alkenes with good yields under mild reaction conditions that decrease these side reactions. The scope of this environmentally benign reaction is thereby extended to a wide variety of boronic acids. A mechanistic study was conducted and suggested a plausible catalytic cycle mechanism, pointing to the importance of the Lewis acidity of the boronic acid used.

    Nightmares are intensive dreams with negative emotional tone. Frequent nightmares can pose a serious clinical problem and in 2001, Tanskanen et al. found that nightmares increase the risk of suicide. However, the dataset used by these authors included war veterans in whom nightmare frequency - and possibly also suicide risk - is elevated. Therefore, re-examination of the association between nightmares and suicide in these data is warranted. We investigated the relationship between nightmares and suicide both in the general population and war veterans in Finnish National FINRISK Study from the years 1972 to 2012, a dataset overlapping with the one used in the study by Tanskanen et al. Our data comprise 71,068 participants of whom 3139 are war veterans. Participants were followed from their survey participation until the end of 2014 or death. Suicides (N = 398) were identified from the National Causes of Death Register. Frequent nightmares increase the risk of suicide: The result of Tanskanen et al. holds even when war experiences are controlled for. Actually nightmares are not significantly associated with suicides among war veterans. These results support the role of nightmares as an independent risk factor for suicide instead of just being proxy for history of traumatic experiences.

    To describe the impact of major loss of telecommunications on general practice in a rural region of Australia. A multi-stage qualitative study. Purposively selected participants were invited to contribute to initial data collection using an online survey, followed by interviews with selected participants. Thematic analysis of the data was performed by both research team members. South-western Victoria, Australia. Individuals from organisations involved in Telstra recovery efforts, disaster management, health care and general practice staff. The survey collected freeform responses from participants. Semi-structured interviews further explored a variety of experiences from purposively selected participants. Organisations and practices in the region were prepared for major disasters, but not for the unusual and 'limited' disaster of losing telecommunications, including lack of Internet access and loss of telephone services. Although alternative measures were found for telecommunications, there was still a significant impact on many health-care-related activities and general practice functionality during the outage period. In particular, there was an increase in duties for administrative staff to compensate for loss of telecommunications. Patient traffic for many services decreased due to uncertainty about availability and continuation of business. The Warrnambool outage could be used as a case study illustrating the dramatic impact of communication loss. Major impacts include changes in patient traffic, increased administrative duties and slowing of patient care. When developing or assessing disaster management plans, general practices should consider the impact of telecommunication loss on functionality and prepare appropriate alternative, accessible and reliable measures. © 2016 National Rural Health Alliance Inc.

    Compiled by INGV, the ISIDE catalog includes high quality recorders of the occurrence times, locations, and magnitude of earthquakes that occurred in the Italy region since 2005-4-16. To study the characteristics of seismicity in Italy, we use the space-time ETAS model and several extended forms. Our results show: 1. Seismicity clustering features are quite different from region to region. According to the ETAS parameters, the whole study region can be divided into four subregions. 2. The rupture geometries of large earthquakes, including the 2009-4-6 M6.3 L'Aquila, the 2012-5-20 M6.1 Emilia, the 2016-0-24 M6.0 Amatrice, the 2016-10-30 M6.2 Norcia earthquakes, control the spatial locations of their direct aftershocks. These direct aftershock aftershock mainly concentrate near, some parts close to the parts on the rupture plane with large slips but seldom overlap with them, indicating that aftershocks are the continuation of the rupture process of the mainshocks. 3. When the focal depth is considered in seismicity modeling, improved probability forecasting of seismicity and hazard assessment can be obtained.

    2000-12-01

    The object of this study is to improve the stability and the economic profit by reducing the radiation-induced degradation rate of polymer material used under the radiation environment. So far, the resistance to radiation-induced oxidation of a polymer has been improved by the stabilizers. They can play an important role in the anti-oxidants that interrupt the radical-mediated oxidation chain reaction. The stabilization effect could be larger than that achieved in an inert-atmosphere irradiation. Stabilization is a function of stabilizer concentration up to a certain threshold, but it is not further improved above this concentration. Beyond the threshold, the rate of radiation-induced oxidation goes up to the rate that is characteristic for the unstabilized polymer. To make up for this weakness, a technique depositing a thin layer of diamond-like carbon (DLC) on the polymer surface was developed for protecting the radiation-induced oxidation in the air.

    The aims of this study of predominately racial/ethnic minority children in foster care (N=360, birth to 19 years old) in Los Angeles, CA were to examine the (1) prevalence of obesity (≥ 95 percentile) and overweight/obese (≥ 85 percentile) upon entrance to foster care (T1) and after 1 year in foster care (T2); (2) comparison of high weight categories to national statistics; (3) relationship of changes in weight status to age, reason for entry into foster care, and placement. Chi-square test and McNemar test comparing paired proportions were used to determine whether there were significant changes in the proportion of high weight categories between T1 and T2. Chi-square test or Fisher's exact test were used to evaluate the association between age, placement, and reason for foster care with the change in weight category. Changes in weight were categorized as (1) decreased in weight, (2) remained at overweight or obese, (3) increased in weight, or (4) remained normal. The proportion of obese and obese/overweight children between ages 2 and 5 were significantly lower at T2 than T1. There were no significant changes in the prevalence of obesity for the total population at T2. Children age 6 or older had a higher prevalence of obesity and overweight/obesity compared to national statistics. Of children at all ages, 64.7% of children of all ages entered foster care with a normal weight and stayed in the normal range during their first year in foster care, 12.2% decreased their weight, 15.4% remained overweight or obese, and 7.7% increased their weight. Age and parental substance use was related to change in weight category from T1 to T2. Children did not become more overweight or obese in foster care; however 28% of the children were obese or overweight upon entry into foster care. Children who are 6 years or older and obese upon entering foster care should be targeted for weight reduction. The pediatric community and child welfare system need to work together by

    Heat transfer studies were conducted at Mach 10.3 on space shuttle orbiter models with the S-2 fillet and C-4 canard retrofit moldlines which were generated in aerodynamic and system design studies to increase the allowable c.g. range of the orbiter. Areas of orbiter most strongly affected were the sides where a shear layer which separated along the wing leading edge impinged. Analytical studies of the heating effect on the thermal-protection system were made which indicated that scar weight on the orbiter sides due to allowances for retrofits of the S-2 fillet and C-4 canard is small (less than about 90 kg (200 lbs) in comparison to the total weight of the retrofit).

  9. The unexpected outcomes of anti-aging, rejuvenation, and life extension studies: an origin of modern therapies.

    Stambler, Ilia

    2014-06-01

    The search for life-extending interventions has been often perceived as a purely academic pursuit, or as an unorthodox medical enterprise, with little or no practical outcome. Yet, in fact, these studies, explicitly aiming to prolong human life, often constituted a formidable, though hardly ever acknowledged, motivation for biomedical research and discovery. At least several modern biomedical fields have originated directly from rejuvenation and life extension research: (1) Hormone replacement therapy was born in Charles-Edouard Brown-Séquard's rejuvenation experiments with animal gland extracts (1889). (2) Probiotic diets originated in Elie Metchnikoff's conception of radically prolonged "orthobiosis" (c. 1900). (3) The development of clinical endocrinology owed much to Eugen Steinach's "endocrine rejuvenation" operations (c. 1910s-1920s). (4) Tissue transplantations in humans (allografts and xenografts) were first widely performed in Serge Voronoff's "rejuvenation by grafting" experiments (c. 1910s-1920s). (5) Tissue engineering was pioneered during Alexis Carrel's work on cell and tissue immortalization (c. 1900-1920). (6) Cell therapy (and particularly human embryonic cell therapy) was first widely conducted by Paul Niehans for the purposes of rejuvenation as early as the 1930s. Thus, the pursuit of life extension and rejuvenation has constituted an inseparable and crucial element in the history of biomedicine. Notably, the common principle of these studies was the proactive maintenance of stable, long-term homeostasis of the entire organism.

    Full Text Available Tripura is the second largest Natural Rubber (NR producing state of India. As most of the NR plantation in the state is rain dependent, it is observed that fluctuation in monsoon poses a serious threat to plantation growth of NR crops. The effect of such shift and fluctuation in climate ranges from surface and ground water level variation, air quality and soil preservation. At present no assessment is available to critically review the impact of large scale NR plantation on environment. In the present paper the effect and impact of annual rainfall deficit, depleted ground water level, average local atmospheric temperature variation and rainfall ground water recharge on NR plantation is studied for the state of Tripura. Considering the large scale accelerated NR plantation in the state, an attempt has been made to figure out the consequences related to water management. The multidirectional environmental threat to the state comprising annual rainfall deficit of 23.3 %, depleted ground water level and significant rise in average atmospheric temperature may severely hit the production of NR in the region. Moreover, the estimated requirement of water to produce ribbed smokes sheet (RSS will may escalate to more than 152140 kiloliters in the next ten years. The predicted amount of wastewater generated (directly or indirectly in RSS collection and industry processing effluents may cause large environmental issue due to their open disposal in many cases. Hence, also claims a threat to the rubber production and growth of the sector.

    Large ultramafic areas exist in Albania, which could be suitable for phytomining with native Alyssum murale. We undertook a five-year field experiment on an ultramafic Vertisol, aimed at optimizing a low-cost Ni-phytoextraction crop of A. murale which is adapted to the Balkans. The following aspects were studied on 18-m2 plots in natural conditions: the effect of (i) plant phenology and element distribution, (ii) plant nutrition and fertilization, (iii) plant cover and weed control and (iv), planting technique (natural cover vs. sown crop). The optimal harvest time was set at the mid-flowering stage when Ni concentration and biomass yield were highest. The application of N, P, and K fertilizers, and especially a split 100-kg ha(-1) N application, increased the density of A. murale against all other species. It significantly increased shoot yield, without reducing Ni concentration. In natural stands, the control of graminaceous weeds required the use of an anti-monocots herbicide. However, after the optimization of fertilization and harvest time, weed control procured little benefit. Finally, cropping sown A. murale was more efficient than enhancing native stands and gave higher biomass and phytoextraction yields; biomass yields progressively improved from 0.3 to 9.0 t ha(-1) and phytoextracted Ni increased from 1.7 to 105 kg ha(-1).

    We present a detailed X-ray variability study of the low mass Active Galactic Nuclei (AGN) NGC 7314 using the two newly obtained XMM-Newton observations ($140$ and $130$ ks), together with two archival data sets of shorter duration ($45$ and $84$ ks). The relationship between the X-ray variability characteristics and other physical source properties (such as the black hole mass) are still relatively poorly defined, especially for low-mass AGN. We perform a new, fully analytical, power spectral density (PSD) model analysis method, which will be described in detail in a forthcoming paper, that takes into consideration the spectral distortions, caused by red-noise leak. We find that the PSD in the $0.5-10$ keV energy range, can be represented by a bending power-law with a bend around $6.7\\times10^{-5}$ Hz, having a slope of $0.51$ and $1.99$ below and above the bend, respectively. Adding our bend time-scale estimate, to an already published ensemble of estimates from several AGN, supports the idea that the bend ...

    Full Text Available Abstract Background Gene and genome duplication is the principle creative force in evolution. Recently, protein subcellular relocalization, or neolocalization was proposed as one of the mechanisms responsible for the retention of duplicated genes. This hypothesis received support from the analysis of yeast genomes, but has not been tested thoroughly on animal genomes. In order to evaluate the importance of subcellular relocalizations for retention of duplicated genes in animal genomes, we systematically analyzed nuclear encoded mitochondrial proteins in the human genome by reconstructing phylogenies of mitochondrial multigene families. Results The 456 human mitochondrial proteins selected for this study were clustered into 305 gene families including 92 multigene families. Among the multigene families, 59 (64% consisted of both mitochondrial and cytosolic (non-mitochondrial proteins (mt-cy families while the remaining 33 (36% were composed of mitochondrial proteins (mt-mt families. Phylogenetic analyses of mt-cy families revealed three different scenarios of their neolocalization following gene duplication: 1 relocalization from mitochondria to cytosol, 2 from cytosol to mitochondria and 3 multiple subcellular relocalizations. The neolocalizations were most commonly enabled by the gain or loss of N-terminal mitochondrial targeting signals. The majority of detected subcellular relocalization events occurred early in animal evolution, preceding the evolution of tetrapods. Mt-mt protein families showed a somewhat different pattern, where gene duplication occurred more evenly in time. However, for both types of protein families, most duplication events appear to roughly coincide with two rounds of genome duplications early in vertebrate evolution. Finally, we evaluated the effects of inaccurate and incomplete annotation of mitochondrial proteins and found that our conclusion of the importance of subcellular relocalization after gene duplication on

    We present a detailed X-ray variability study of the low-mass active galactic nuclei (AGN) NGC 7314 using the two newly obtained XMM-Newton observations (140 and 130 ks), together with two archival data sets of shorter duration (45 and 84 ks). The relationship between the X-ray variability characteristics and other physical source properties (such as the black hole mass) are still relatively poorly defined, especially for low-mass AGN. We perform a new, fully analytical, power spectral density (PSD) model analysis method, which will be described in detail in a forthcoming paper, that takes into consideration the spectral distortions, caused by red-noise leak. We find that the PSD in the 0.5-10 keV energy range, can be represented by a bending power law with a bend around 6.7 × 10-5 Hz, having a slope of 0.51 and 1.99 below and above the bend, respectively. Adding our bend time-scale estimate, to an already published ensemble of estimates from several AGN, supports the idea that the bend time-scale depends linearly only on the black hole mass and not on the bolometric luminosity. Moreover, we find that as the energy range increases, the PSD normalization increases and there is a hint that simultaneously the high-frequency slope becomes steeper. Finally, the X-ray time-lag spectrum of NGC 7314 shows some very weak signatures of relativistic reflection, and the energy resolved time-lag spectrum, for frequencies around 3 × 10-4 Hz, shows no signatures of X-ray reverberation. We show that the previous claim about ks time delays in this source, is simply an artefact induced by the minuscule number of points entering during the time-lag estimation in the low-frequency part of the time-lag spectrum (i.e. below 10-4 Hz).

  16. COMPENSATORY OPPORTUNITIES OF THE SMALL INTESTINE AFTER EXTENSIVE DISTAL AND PROXIMAL RESECTION (EXPERIMENTAL STUDY

    2017-01-01

    Full Text Available Resection of certain parts of the small intestine is common in clinical practice for various diseases and traumatic injuries. The significant decrease in bowel functioning leads to the development of a specific “short bowel syndrome” (SBS. There is an opinion that the remaining parts of the intestine after resection perform a compensatory function as a result of the development of morphological changes in the intestinal wall. Histological examination of the intestinal wall with evolved compensatory changes is of undoubted interest from the scientific and clinical point of view.Material and Methods. To create the experimental model of SBS, 107 laboratory Wistar male rats were used, weighing 500–600 g, which underwent resection with removal of 1/2 or 2/3 of the small intestine length in proximal or distal parts. The observation period for the animals was 1, 2, 4 and 6 months. Upon expiration of indicated dates, samples of the small intestine and liver were taken from rats for autopsy to be used for histological examination. At the indicated terms, the animals had signs of SBS (diarrhea, weight loss, as well as morphological changes in the intestinal mucosa.Results and Conclusion. According to the results of the study, we concluded that the loss of 1/2 the length of the small intestine is overcome without consequences, and the loss of 2/3 of its length, especially of its proximal part, is accompanied by a longer period of adaptation and more significant morphological alteration of the mucosa, which has to perform not only digestion, but also absorption.

    This prospective study included 152 elderly patients (mean age, 80 years; range, 72-88 years) with a hip fracture treated surgically. Comorbidities were evaluated, and B-type natriuretic peptide was measured at baseline and at postoperative days 4 and 5 in addition to troponin I. Major cardiac events were recorded, and 1-year mortality was assessed. Comorbidity models with the important multivariate predictors of 1-year mortality were analyzed. Overall, 9 patients (6%) experienced major cardiac events postoperatively during their hospitalization. Three patients (2%) died postoperatively, at days 5, 7, and 10, from autopsy-confirmed myocardial infarction. Three patients (2%) experienced a nonfatal myocardial infarction, and 3 patients (2%) experienced acute heart failure. At 1-year follow-up, 37 patients (24%) had died. Age older than 80 years (P=.000), renal failure (P=.016), cardiovascular disease (P=.003), respiratory disease (P=.010), Parkinson disease (P=.024), and dementia (P=.000) were univariate predictors of 1-year mortality. However, in the multivariate model, only age older than 80 years (P=.000) and dementia (P=.024) were important predictors of 1-year mortality. In all comorbidity models, age older than 80 years and dementia were important predictors of 1-year mortality. Postoperative increase in B-type natriuretic peptide was the most important predictor of 1-year mortality. Receiver operating characteristic curve analysis showed a threshold of 90 ng/mL of preoperative B-type natriuretic peptide (area under the curve=0.773, 95% confidence interval, 0.691-0.855, Pyear mortality. Similarly, a threshold of 190 ng/mL of postoperative B-type natriuretic peptide (area under the curve=0.753, 95% confidence interval, 0.662-0.844, P<.001) had 70% sensitivity and 77% specificity to predict the study endpoint.

    We re-examined experimental model results using half-body specimens with intact extensor mechanisms and navigation to evaluate cruciate-retaining (CR) and posterior stabilized (PS) total knee arthroplasty (TKA) component gaps through an entire range of motion. Six sequential testing regimens were conducted with the knee intact, with a CR TKA in place, and with a PS TKA in place, with and without 22 N traction in place at each stage. Each of 10 knees was taken through six full ranges of motion from 0° to 120° at every stage using a navigated knee system to record component gapping. No significant difference was found between loaded and unloaded component gaps, and no significant differences were found in component gapping between CR and PS TKAs throughout a full range of motion. Flexion-extension gap measurements were significantly different from previously published data (at 90° flexion). No difference was found in kinematics when comparing CR and PS TKA component designs. Our results suggest that intact extensor mechanisms may be required to perform proper kinematic studies of TKA. Our findings provide evidence that the extensor mechanism may play a major role in the flexion-extension gaps in cadaveric knees.

    Extensive green roofs with a thin growing medium require minimal maintenance, and in general no irrigation. The proper functioning of such systems rests with their structural constituents, especially with the substrate used for planting. An extensive green roof with poorly developed vegetation and with a soil layer of a maximum thickness of 5 cm mixed with local stripped topsoil with crushed bricks and green waste was studied with respect to the hydrological behavior. The substrate classified as loam comprises a significant proportion of very fine particles and thus it is prone to clogging up of soil pores and forming of fissures on the surface. The green roof studied is well equipped for measuring meteorological data including air temperature, wind speed and direction, net radiation, relative humidity, and rainfall intensity. The meteorological information on the site is completed by soil temperature measurement. The 12 m long transect is equipped with eight time domain reflectometry probes (TDR) to monitor soil water content. Soil physical properties (bulk density, porosity, grain size distribution) and soil hydraulic characteristics (soil water retention curve) were obtained. The numerical modeling of transient soil water movement in the green roof substrate was performed using a two-dimensional model based on the Richards' equation. Results were compared with the soil water content data acquired. Six alternative scenarios were formulated to discuss possible improvement of green roof functioning and four selected scenarios were simulated. The study helped us to improve our understanding of the flow processes through the green roof soil system under study. The alternative scenario simulations allowed hydrological assessment of roof construction amendments. The research was realized as a part of the University Centre for Energy Efficient Buildings supported by the EU and with financial support from the Czech Science Foundation under project number 14-10455P.

    sleep disturbance in elderly inpatients with depression in the acute treatment duration and its association with 1-year outcome were observed,so as to give reference for reasonable treatment of sleep disturbance in the aged.Methods In an observationally naturalistic study,69 consecutive elderly inpatient with ICD-10 criteria for depressive disorders were included.The sleep disturbance was assessed with the Pittsburgh Sleep Quality Index (PSQI) at baseline,2-week,4-week treatment and 1-year follow-up,and total score of 8 or higher was defined as having sleep disturbance.The HAMD and HAMA for illness severity,and MMSE for cognitive functioning was assessed simuhaneously.At the 1-year follow-up,the Global Assessment Function (GAF) was used for assessing social functioning as well.Results The PSQI scores at baseline,2-week,3-week and 1-year follow-up were (15.4±3.8),(12.0±4.6),(9.4±4.3) and (8.5±4.7),and repeated measured variance of analysis showed the differences of scores between 2-week,4-week and baseline were statistically significant (F=48.85,40.92;both P<0.05),while the difference between 4-week and 1-year follow-up was not significant (F=1.86,P=0.178).At 2-and 4-week treatment,the rate of co-therapy of hypnotics was higher inpatients with sleep disturbance.The decreased rates ofPSQI score at 2-week was correlated to the decreased rate of HAMD score at 2-week (r=0.33,P=0.006) and 4-week (r=0.40; P=0.001),but not at 1-year follow-up (r=0.16,P=0.228).At 1-year follow-up,having sleep disturbance was significantly associated with higher HAMD score (OR=11.56,Wald X2=4.26; P<0.05),but the associations with HAMA,MMSE and GAF scores were not significant.Conclusion Sleep disturbance in the elderly inpatients with depression could be improved with effective antidepressant treatment,and improvement in early treatment phase could predict better therapeutic effect in the acute phase.The residual sleep disturbance at 1-year follow-up may be an important residual symptom of

    Full Text Available The applicability of capillary electrophoresis for the analysis of four extensively used penicillin derivatives (benzylpenicillin, ampicillin, amoxicillin, oxacilllin has been studied. Because of structural similarities, the electrophoretic behavior of these derivatives is very similar; consequently an efficient separation using the conventional capillary zone electrophoresis is hard to be achieved. Their simultaneous separation was solved by using micellar electrokinetic capillary chromatography, the separation being based on the differential partition of the analytes between the micellar and aqueous phase. Using a buffer solution containing 25 mM sodium tetraborate and 100 mM sodium dodecyl sulfate as surfactant, at a pH of 9.3, applying a voltage of + 25 kV at a temperature of 25 °C, we achieved the simultaneous separation of the studied penicillin derivatives in less then 5 minutes. The separation conditions were optimized and the analytical performance of the method was evaluated in terms of precision, linearity, limit of detection, and quantification. Also, a simple capillary zone electrophoresis method was applied to study the stability of the studied penicillin derivatives in water at different temperatures, using ciprofloxacin hydrochloride as internal standard. It was observed that the extent of the hydrolysis of penicillins in water is highly dependent on the time and also temperature.

    In the CLARINET study, lanreotide Autogel (depot in USA) significantly prolonged progression-free survival (PFS) in patients with metastatic pancreatic/intestinal neuroendocrine tumours (NETs). We report long-term safety and additional efficacy data from the open-label extension (OLE). Patients with metastatic grade 1/2 (Ki-67 ≤ 10%) non-functioning NET and documented baseline tumour-progression status received lanreotide Autogel 120 mg (n = 101) or placebo (n = 103) for 96 weeks or until death/progressive disease (PD) in CLARINET study. Patients with stable disease (SD) at core study end (lanreotide/placebo) or PD (placebo only) continued or switched to lanreotide in the OLE. In total, 88 patients (previously: lanreotide, n = 41; placebo, n = 47) participated: 38% had pancreatic, 39% midgut and 23% other/unknown primary tumours. Patients continuing lanreotide reported fewer adverse events (AEs) (all and treatment-related) during OLE than core study. Placebo-to-lanreotide switch patients reported similar AE rates in OLE and core studies, except more diarrhoea was considered treatment-related in OLE (overall diarrhoea unchanged). Median lanreotide PFS (core study randomisation to PD in core/OLE; n=101) was 32.8 months (95% CI: 30.9, 68.0). A sensitivity analysis, addressing potential selection bias by assuming that patients with SD on lanreotide in the core study and not entering the OLE (n=13) had PD 24 weeks after last core assessment, found median PFS remaining consistent: 30.8 months (95% CI: 30.0, 31.3). Median time to further PD after placebo-to-lanreotide switch (n=32) was 14.0 months (10.1; not reached). This OLE study suggests long-term treatment with lanreotide Autogel 120 mg maintained favourable safety/tolerability. CLARINET OLE data also provide new evidence of lanreotide anti-tumour benefits in indolent and progressive pancreatic/intestinal NETs. © 2016 The authors.

    Assurance GDSTM for Salmonella Tq has been validated according to the AOAC INTERNATIONAL Methods Committee Guidelines for Validation of Microbiological Methods for Food and Environmental Surfaces for the detection of selected foods and environmental surfaces (Official Method of AnalysisSM 2009.03, Performance Tested MethodSM No. 050602). The method also completed AFNOR validation (following the ISO 16140 standard) compared to the reference method EN ISO 6579. For AFNOR, GDS was given a scope covering all human food, animal feed stuff, and environmental surfaces (Certificate No. TRA02/12-01/09). Results showed that Assurance GDS for Salmonella (GDS) has high sensitivity and is equivalent to the reference culture methods for the detection of motile and non-motile Salmonella. As part of the aforementioned validations, inclusivity and exclusivity studies, stability, and ruggedness studies were also conducted. Assurance GDS has 100% inclusivity and exclusivity among the 100 Salmonella serovars and 35 non-Salmonella organisms analyzed. To add to the scope of the Assurance GDS for Salmonella method, a matrix extension study was conducted, following the AOAC guidelines, to validate the application of the method for selected spices, specifically curry powder, cumin powder, and chili powder, for the detection of Salmonella.

    Full Text Available Problem statement: Jordans agricultural extension service is seriously under-staffed and its effectiveness is consequently compromised. Reservations are being expressed about the performance and capability of the agricultural extension system in Jordan. The performance of this sector has been disappointing and has failed to transfer agricultural technology to the farmers. The main objective of this study is to assess the effectiveness of Jordans agricultural extension services. Approach: The effect of extension services on olive productivity in the study area was investigated. A total number of 60 olive producers were selected to be interviewed for this study. This number was enough to achieve the study objectives. The interviewed producers were distributed almost equally within olive production locations in the study area. The sample obtained through the simple random sampling technique. The two groups had been chosen and distributed randomly into an experimental group (30 farmers; 10 for each source of extension service and control group (30 farmers. The experimental group received extension services and the control group received no extension services. Two interview-cum-structured questionnaires were designed and used to collect information and data for this study. The first instrument was designed for farmers who received extension services and the second from farmers who received no extension services. Another questionnaire was designed for administrators of extension organizations concerned with providing extension services to farmers. To find the differences that may exist between two studied groups, One Way Analysis of Variance (ANOVA, t-test and LSD test via Statistical Package for Social Sciences software (SPSS were used. The average net profit obtained from an area of one dynamo of olive farm was the main item to be considered in determining the effectiveness of agricultural extension activities. Results and Conclusion: The results of

    Tongue strength is a useful indicator of oral function and has been found to decrease with aging and reduced physical functioning. The present study aimed to assess the relationships of tongue strength with physical function, mental function, and nutritional status, and also between these factors and 1-year outcomes, to determine whether tongue strength is related to life expectancy in elderly people needing nursing care. The subjects were 140 elderly individuals requiring needing nursing care (49 men and 91 women; ≥65 years). The investigated items included sex, age, activities of daily living (ADL), comorbidity, cognitive function, nutritional status, eating function, occlusal support, and tongue strength. Furthermore, a follow-up study was conducted 1 year later, and factors related to death were identified. The mean tongue strength of the total 140 subjects was 20.3 ± 8.6 kPa. Tongue strength was assessed relative to each of the investigated items, using the t test and one-way analysis of variance. Tongue strength was significantly related to ADL, comorbidity, cognitive function, calf circumference, food intake, and occlusal support. Fifteen subjects were found to have died at the 1-year follow-up study. We assessed the relationships of 1-year outcomes with each of the factors examined, and 1-year outcomes were found to be significantly related to ADL and tongue strength.

  13. Lagrangian study of surface transport in the Kuroshio Extension area based on simulation of propagation of Fukushima-derived radionuclides

    2013-01-01

    Lagrangian approach is applied to study near-surface large-scale transport in the Kuroshio Extension area using a simulation with synthetic particles advected by AVISO altimetric velocity field. A material line technique is applied to find the origin of water masses in cold-core cyclonic rings pinched off from the jet in summer 2011. Tracking and Lagrangian maps provide the evidence of cross-jet transport. Fukushima derived caesium isotopes are used as Lagrangian tracers to study transport and mixing in the area a few months after the March of 2011 tsunami that caused a heavy damage of the Fukushima nuclear power plant (FNPP). Tracking maps are computed to trace the origin of water parcels with measured levels of Cs-134 and Cs-137 concentrations collected in two R/V cruises in June and July 2011 in the large area of the Northwest Pacific. It is shown that Lagrangian simulation is useful to finding the surface areas that are potentially dangerous due to the risk of radioactive contamination. The results of sim...

    The aim of this study was to investigate perioperative morbidity in operative interventions in distal radiusfractures, comparing the operative approach from volar and dorsal. Only problems, resulting from the operative approach towards the distal aspect of the radius, were examined. In a Case-Control-Study, we investigated patients with operative by plate-osteosynthesis treated distal radius-extensions-fractures. During 3 years we investigated 92 patients. 49 were operated with a volar approach, and after changing the operative management, consecutive 43 patients with a dorsal approach to the distal radius. Indications for operative treatment were not changed. The approach to the distal aspect of the radius corresponded to the recent guidelines. Further perioperative procedures were identical, including procedures in anesthesiology. Datas of patients have been investigated for epidemiology, kind of operations, point of time in treatment, duration of operation, X-Ray, immobilisation and time of inhospital stay as well as all documented complications. It has been shown, that in respect of all criterias, concerning length of operation (106 vs. 83 min), intraoperative X-Ray (3.0 vs. 1.65 min) as well as postoperative immobilisation (33 vs. 25 days), and documented incidences of complications like secondary wound-healing (19/49 vs. 0/43) or nerval irritations (13/49 vs. 1/43), the dorsal osteosynthesis is definitively to be favored.

    Several supernova types are thought to explode via the gravitational collapse of the core of massive stars at the end of their lifetimes. The great observational diversity has not been fully understood even if it clearly involves the progenitor masses and configurations at the time of explosion. These Supernovae, called Core Collapse Supernovae (CC SNe), are expected to dominate the counts of SNe observed at high redshifts and to be the only observable probe of the first generation stars (Pop III). Recently indicated as reliable distance indicators (Hamuy 02, Pastorello `03), CC SNe are objects of great interest but significantly less studied in comparison with the Termonuclear ones. With the aim to understand better the reasons of the heterogeneous behaviour , we have started an extensive study of the properties of SN II with different observational features (luminosity, velocity, etc..). Here we present the last results on our first observed target, SN2005ay, a Type IIP supernova observed in an extended way from the Ultraviolet wavelengths, provided by the GALEX , to the Optical and near-IR , obtained with IISP (Italian Intensive Supernova Program).

    Nutritional epidemiology is an inherently complex and multifaceted research area. Dietary intake is a complex exposure and is challenging to describe and assess, and links between diet, health, and disease are difficult to ascertain. Consequently, adequate reporting is necessary to facilitate comprehension, interpretation, and generalizability of results and conclusions. The STrengthening the Reporting of OBservational studies in Epidemiology (STROBE) statement is an international and collaborative initiative aiming to enhance the quality of reporting of observational studies. We previously presented a checklist of 24 reporting recommendations for the field of nutritional epidemiology, called “the STROBE-nut.” The STROBE-nut is an extension of the general STROBE statement, intended to complement the STROBE recommendations to improve and standardize the reporting in nutritional epidemiology. The aim of the present article is to explain the rationale for, and elaborate on, the STROBE-nut recommendations to enhance the clarity and to facilitate the understanding of the guidelines. Examples from the published literature are used as illustrations, and references are provided for further reading. PMID:28916567

    Conclusion: Sniffing position provides better glottis exposure and it is easier to intubate a patient in the sniffing position as compared to simple head extension position. Sniffing position should therefore be used as initial position when attempting intubation.

    Background Inhibition of the quadriceps muscle and reduced knee-extension strength is common shortly following total knee arthroplasty (weeks to months), due to reduced voluntary activation of the quadriceps muscle. In healthy subjects, strength training with heavy loads is known to increase agonist muscle activity, especially if the exercise is conducted using rapid muscle contractions. Purpose The purpose of this study was to examine if patients with total knee arthroplasty could perform rapid knee-extensions using a 10 RM load four to eight weeks after surgery, and the degree to which rapid knee-extensions were associated with greater voluntary quadriceps muscle activity during an experimental strength training session, compared to that elicited using slow knee-extensions. Study Design A randomized cross-over study. Methods Twenty-four patients (age 66.5) 4-8 weeks post total knee arthroplasty randomly performed one set of five rapid, and one set of five slow knee-extensions with the operated leg, using a load of their 10 repetition maximum, while surface electromyography recordings were obtained from the vastus medialis and lateralis of the quadriceps muscle. Results Data from 23 of the 24 included patients were analyzed. Muscle activity was significantly higher during rapid knee-extensions (120.2% [10th-90th percentile: 98.3-149.1]) compared to slow knee-extensions (106.0% [88.8-140.8]) for the vastus lateralis (pknee-extensions were performed at a median angular velocity of 19.7 degrees/sec (13.7-24.4) and 51.4 degrees/sec (28.9-63.1), respectively Conclusion Four to eight weeks after their total knee arthroplasty, the patients in the present study were able to conduct rapid knee-extensions according to the experimental protocol with an approximately doubled angular velocity compared to slow knee-extensions. This was associated with increased muscle activity in the vastus lateralis when compared to slow knee-extensions, but not in the vastus medialis. Whether

    Introduction. Well-trained and highly motivated community health workers are critical for delivery of community-based health care services. Understanding what motivates especially community health care providers for better community health requires the use of psychometrically reliable and valid scale. This study was conducted to validate job motivation scale in Gamo Gofa Zone, Southern Ethiopia. Methods. A cross-sectional study was conducted in 150 health care posts in Gamo Gofa Zone, from February 01, 2013, to March 01, 2013. A total of 301 participants responded to questionnaires asking about sociodemographic characteristics and job motivation. Exploratory factor analysis with principal component extraction and varimax with Kaiser Normalization rotation were employed to develop scales for job motivation. Eigenvalues greater than 1 were used as criterion of extraction. Items with item factor loadings less than 0.4 and double loaded items were dropped. Alpha and exploratory factor analyses were examined to test reliability and validity of the scale. Results. During exploratory factor analysis eight factors emerged from the three dimensions of job motivation scale, namely, educational career, workload, financial incentive, supervisor encouragement, community recognition, access to infrastructure, living condition, and better achievement in work. The factor loadings of the items in each dimension ranged from 0.58 to 0.83. Crobach's alpha of the scales ranged from 0.79 to 0.90. To check validities of the scales developed in this study, the previous studies conducted to develop job motivation scale were used. Conclusion. Although the present scale has the potential to measure the job motivation of health extension workers and it is low in cost and easy to administer and analyze, it should be field-tested at different settings.

    During movement tasks, patients with medial compartment knee osteoarthritis use compensatory strategies to minimise the joint load of the affected leg. Movement strategies of the knees and trunk have been investigated, but less is known about movement strategies of the pelvis during advancing functional tasks, and how these strategies are associated with leg extension power. The aim of the study was to investigate pelvic movement strategies and leg extension power in patients with end-stage medial compartment knee osteoarthritis compared with controls. 57 patients (mean age 65.6 years) scheduled for medial uni-compartmental knee arthroplasty, and 29 age and gender matched controls were included in this cross-sectional study. Leg extension power was tested with the Nottingham Leg Extension Power-Rig. Pelvic range of motion was derived from an inertia-based measurement unit placed over the sacrum bone during walking, stair climbing and stepping. Patients had lower leg extension power than controls (20-39 %, P 0.06). Furthermore, an inverse association (coefficient: -0.03 to -0.04; R (2) = 13-22 %) between leg extension power and pelvic range of motion during stair and step descending was found in the patients. Compared to controls, patients with medial compartment knee osteoarthritis use greater pelvic movements during advanced functional performance tests, particularly when these involve descending tasks. Further studies should investigate if it is possible to alter these movement strategies by an intervention aimed at increasing strength and power for the patients.

    The emotional selection hypothesis describes a cyclical process that uses dreams to modify and test select mental schemas. An extension is proposed that further characterizes these schemas as facilitators of human need satisfaction. A pilot study was conducted in which this hypothesis was tested by assigning 100 dream reports (10 randomly selected from 10 dream logs at an online web site) to one or more categories within Maslow's hierarchy of needs. A "match" was declared when at least two of three judges agreed both for category and for whether the identified need was satisfied or thwarted in the dream narrative. The interjudge reliability of the judged needs was good (92% of the reports contained at least one match). The number of needs judged as thwarted did not differ significantly from the number judged as satisfied (48 vs. 52%, respectively). The six "higher" needs (belongingness, esteem, cognitive, aesthetic, self-actualization, and transcendence) were scored significantly more frequently (81%) than were the two lowest or "basic" needs (physiological and safety, 19%). Basic needs were also more likely to be judged as thwarted, while higher needs were more likely to be judged as satisfied. These findings are discussed in the context of Maslow's hierarchy of needs as a framework for investigating theories of dream function, including the emotional selection hypothesis and other contemporary dream theories.

    We carried out an extensive observational study of the Slowly Pulsating B (SPB) star, HD 25558. The ~2000 spectra obtained at different observatories, the ground-based and MOST satellite light curves revealed that this object is a double-lined spectroscopic binary with an orbital period of about 9 years. The observations do not allow the inference of an orbital solution. We determined the physical parameters of the components, and found that both lie within the SPB instability strip. Accordingly, both show line-profile variations due to stellar pulsations. Eleven independent frequencies were identified in the data. All the frequencies were attributed to one of the two components based on Pixel-by-pixel variability analysis of the line profiles. Spectroscopic and photometric mode identification was also performed for the frequencies of both stars. These results suggest that the inclination and rotation of the two components are rather different. The primary is a slow rotator with ~6 d period, seen at ~60 deg i...

  3. Applicability of CDM to civil engineering projects case study on reduction of CO2 emission by port extension

    This paper investigates the applicability of CDM to civil engineering projects through a case study on the project to extend Port Samainda in Indonesia. The goal of this project is to improve the physical distribution system of the port so that it can accommodate increasing future demand for the cargo transportation. Based on the project report by JICA (2002), we first outline the predicted demand for the cargo transportation and select possible three options in which a cargo vessel with different capabilities and respective port facilities are assigned. For each option, CO2 emissions from both cargo and dredging vessels are predicted and compared. It is found that the total CO2 emission may be reduced significantly by introducing a large-draft vessel and deep navigation channels. This feature becomes more prominent if a traveling distance of the cargo vessels is long enough so that CO2 emissions from cargo vessels dominates those of dredging vessels. This observation supports the applicability of CDM to civil engineering projects because reduction of the CO2 emission is attained by improving distribution systems through civil engineering works such as extension of the port and the maintenance dredging. Finally, we discuss future problems to be investigated for the practical application of CDM to a civil engineering project.

    HANARO is operated with the cycle length of 28 days at 30MW and thus about 9 cycles a year. Three 36-element assemblies and two 18-element assemblies are discharged in the core and refueled. About 27 36-element assemblies and 18 18-element assemblies are consumed during a year. To reduce the consumption of fuel assemblies, the methods extending the cycle length and changing the fuel reloading pattern were studied in this paper. These two methods make the maximum linear power higher than current value. The excess reactivity at the end of cycle for the cycle length of 29.5 and 30 days is reduced to 14.4 mk and 11.0 mk. By the extension of the cycle length, more than two 36-element fuel assemblies are saved during a year. When the fuel reloading pattern is changed, the excess reactivity at the end of cycle has the value from 14 mk to 23 mk and two 18-element assemblies are saved during a year. But it is needed to manage the irradiation tests in the core because of decreasing the excess reactivity.

    1991-04-01

    Relative levels of different alpha-amylase mRNAs were assessed by primer extension experiments using RNA prepared from aleurone of barley (Hordeum vulgare L. cv. Himalaya). Three different aleurone systems were studied: protoplasts prepared from aleurone layers, isolated aleurone layers, and aleurone from germinated grain. Oligonucleotide primers specific for the low-pI and high-pI alpha-amylase groups allowed the levels of different alpha-amylase mRNAs to be assessed both within and between the two groups. In all aleurone systems the same set of alpha-amylase mRNAs was produced in response to either applied gibberellic acid (aleurone protoplasts, isolated aleurone layers) or, presumably, native gibberellin(s) (germinated grain). This result indicates that the same set of genes is being expressed in each case. Differences were observed between the different aleurone systems in regulation of levels of alpha-amylase mRNAs. In particular, the regulation of alpha-amylase mRNA levels in aleurone of germinated grain has unique features which are not adequately explained by the response of isolated aleurone layers to gibberellic acid.

    In an ongoing open-label extension (OV-1004), patients with Lennox-Gastaut syndrome who had completed 1 of 2 randomized controlled trials (OV-1002 [Phase II] or OV-1012 [Phase III]) are receiving clobazam at dosages ≤2.0 mg/kg/day (≤80 mg/day). Of 306 eligible patients from OV-1002 or OV-1012, 267 entered the open-label extension. As of the interim date, July 1, 2010, 213 patients (79.8%) had remained in the trial, and 189 had received clobazam for ≥12 months, 128 for ≥18 months, and 94 for ≥24 months. Median percentage decreases in average weekly rates of drop seizures were 71.1% and 91.6% at Months 3 and 24. Mean modal and mean maximum daily dosages were 0.94 mg/kg and 1.22 mg/kg for those who had received clobazam for ≥1 year. The 4 most common adverse events were upper respiratory tract infection (18.4%), fall (14.2%), pneumonia (13.9%), and somnolence (12.7%). Clobazam's adverse event profile was consistent with its profile in controlled trials.

    为了解决传统可拓模式分类器只适合用于模式类别较少和一维数据等缺点,针对可拓学中可拓距和关联函数的特点,提出了采用可拓距和关联函数新的可拓模式分类器,包括平均关联函数法、K最大关联函数法和最大关联函数法.详细介绍三种可拓模式分类器的设计步骤;并针对平均样本法、平均距离法、K近邻法、最近邻法和三种可拓模式分类器,采用二维平面数据、多维向量数据和手指静脉图像特征矩阵数据进行实验对比分析.实验结果表明:新的基于可拓距与关联函数的可拓模式分类器算法不仅可以解决模式类别较多的多维数据问题,分类效果也可以达到经典的K近邻分类器或最近邻分类器的分类水平.%In order to overcome some defects that the traditional extension pattern classifier is only suitable for little small pattern classification and one -dimensional data, according to the characteristics of the extension distance and the correlation function of extension, three new algorithms of extension pattern classifier were proposed. The algorithms are the average correlation function, K - maximum correlation function and maximum correlation function based on the extension distance and the extension correlation function. The steps of the extension pattern classifiers were introduced in detail. For these classifiers of the average sample, the average distance, the k - nearest neighbor, the nearest neighbor and the extension pattern classifiers, the two - dimensional data, the multi - dimensional vector data and the matrix data of finger vein image feature were used to compare and analyze the classification effects of the extension pattern classifiers. Experimental results show that the new extension pattern classifiers can deal with multiple patterns and multi - dimensional data, and its classification result can reach the level of k - nearest neighbor classifier or nearest neighbor

    Background Clofarabine is a nucleoside analog with activity in children with ALL. Based on the hypothesis that clofarabine inhibits DNA repair following exposure to DNA damaging agents, we designed a phase 1 and extension study to evaluate the combination of clofarabine with cyclophosphamide in adult patients with relapsed/refractory ALL. Methods The continual reassessment method (CRM) was used to define the maximum tolerated dose (MTD). Results Fifty patients with a median age of 30 years (range 21–72 years) were enrolled of whom 30 patients were part of the phase 1 group. Clofarabine 40 mg/m2 iv daily x 3 days and cyclophosphamide 200 mg/m2 iv q 12 hours x 3 days were established as the MTD. Dose limiting toxicities were diarrhea, transaminase elevations, and skin rashes. The response rate of the whole study group was 14% including 10% of patients who achieved complete remission (CR) or CR without platelet recovery. Three responses occurred in patients with primary refractory disease. Early mortality (< 30 days) was 6%. The median response duration was 69 days (range 5–315 days). Median overall survival was about 3 months. Compared to day 1 (cyclophosphamide alone), H2AX phosphorylation was increased on day 2 when clofarabine and cyclophosphamide were administered as a couplet (n = 8). Conclusions The combination of clofarabine plus cyclophosphamide at the doses used in this study and in a group of heavily pretreated patients with ALL is only moderately effective. Other doses, alternative schedules, or a more favorable patient population may achieve better results. (Word count: 248) PMID:24440659

    Comparative study of incidence of disk protrusion was performed on the basis of MR imaging in a state of flexion versus extension. The results showed that the incidnece of disk protrusion at each disk level was generally higher on the extension images than on the flexion images at the corresponding levels. The degree of difference in the incidence of the disk protrusion on flexion and extension was the greatest at the mid-cervical level spine. Based on the results with respect to features of the cervical spine in extension and flexion, it appears that the difference in incidence of disk protrusion is probably caused by movement in response to bending of the cervical spine. These results may provide information concerning the dynamic of cervical disks and may partly explain cases in which patients have symptoms of cervical myelopathy and/or radiculopathy but have no disk protrusion on images in the neutral position.

    Hypoparathyroidism is characterized by inadequate parathyroid hormone (PTH), resulting in hypocalcemia, hyperphosphatemia, and bone abnormalities. Adults with hypoparathyroidism treated with recombinant human PTH, rhPTH(1-84), in the 24-week, phase III REPLACE study maintained serum calcium despite reductions in oral calcium and active vitamin D. This study assessed the long-term efficacy and safety of rhPTH(1-84) for hypoparathyroidism. This was a 24-week, open-label, flexible-dose extension study of REPLACE (REPEAT) conducted in 3 outpatient centers in Hungary. Patients who previously completed or enrolled in REPLACE received 50 μg/day rhPTH(1-84), escalated to 75 and then to 100 μg/day, if needed, to reduce active vitamin D and oral calcium. The primary endpoint was ≥50% reduction in oral calcium (or ≤500 mg/day) and active vitamin D (or calcitriol ≤0.25 μg/day or alfacalcidol ≤0.50 μg/day) with normocalcemia. Twenty-four patients (n = 16 previously treated with rhPTH[1-84]; n = 8 rhPTH[1-84]-naïve) were enrolled and completed the study. At Week 24, 75% of patients (95% confidence interval [CI], 53.3-90.2%) achieved the study endpoint; 58% eliminated oral calcium and active vitamin D. Urinary calcium, serum phosphate, and calcium × phosphate (Ca × P) product decreased by Week 24. Mean serum bone turnover markers increased with rhPTH(1-84). Treatment-emergent adverse events (TEAEs) were reported by 92% of patients. No serious adverse events (AEs) occurred. This study used a simplified treatment algorithm intended to better mimic typical clinical practice and demonstrated the extended efficacy and safety of rhPTH(1-84) in patients with hypoparathyroidism and confirmed the REPLACE findings. Sustained rhPTH(1-84) efficacy up to 48 weeks was observed despite treatment interruption between studies.

    This study compared the efficacy of collagenase treatment and needle fasciotomy for contracture of the metacarpophalangeal (MCP) joint in Dupuytren disease. This is a prospective, single-blinded, randomized study with follow-up 1 week and 1 year after treatment. One hundred and forty patients with an MCP contracture of 20° or more in a single finger were enrolled, of whom 69 patients were randomized to collagenase treatment and 71 patients to needle fasciotomy. The patients were followed at 1 week and were examined by a physiotherapist after 1 year. Measurements of joint movement and grip strength were recorded as well as patient-perceived outcomes measured by the Unité Rhumatologique des Affections de la Main (URAM) questionnaire and a visual analog scale (VAS) for the estimation of procedural pain and subjective treatment efficacy. Eighty-eight percent of the patients in the collagenase group and 90% of the patients in the needle fasciotomy group had a reduction in their MCP contracture to less than 5° 1 week after treatment, and the median gains in passive MCP movement were 48° and 46°, respectively. The median VAS score for procedural pain was 4.9 of 10 in the collagenase group and 2.7 of 10 in the needle fasciotomy group. After 1 year, 90% of the patients in both groups had full extension of the treated MCP joint. One patient in each group had a recurrence of the contracture. The median improvement in URAM score was 8 units in both groups and the VAS estimation of treatment efficacy by the patients was 8.7 of 10 in both groups. There was no significant difference between the treatment outcomes after collagenase and needle fasciotomy treatment after 1 year. Therapeutic I.

    To improve the quality of care and reduce the healthcare costs of elderly patients with a hip fracture, surgeons and geriatricians collaborated intensively due to the special needs of these patients. After treatment at the Centre for Geriatric Traumatology (CvGT), we found a significant decrease in the 1-year mortality rate in frail elderly patients compared to the historical control patients who were treated with standard care. The study aimed to evaluate the effect of an orthogeriatric treatment model on elderly patients with a hip fracture on the 1-year mortality rate and identify associated risk factors. This study included patients, aged 70 years and older, who were admitted with a hip fracture and treated in accordance with the integrated orthogeriatric treatment model of the CvGT at the Hospital Group Twente (ZGT) between April 2008 and October 2013. Data registration was carried out by several disciplines using the clinical pathways of the CvGT database. A multivariate logistic regression analysis was used to identify independent risk factors for 1-year mortality. The outcome measures for the 850 patients were compared with those of 535 historical control patients who were managed under standard care between October 2002 and March 2008. The analysis demonstrated that the 1-year mortality rate was 23.2 % (n = 197) in the CvGT group compared to 35.1 % (n = 188) in the historical control group (p year mortality were male gender (odds ratio (OR) 1.68), increasing age (OR 1.06), higher American Society of Anesthesiologists (ASA) score (ASA 3 OR 2.43, ASA 4-5 OR 7.05), higher Charlson Comorbidity Index (CCI) (CCI 1-2 OR 1.46, CCI 3-4 OR 1.59, CCI 5 OR 2.71), malnutrition (OR 2.01), physical limitations in activities of daily living (OR 2.35), and decreasing Barthel Index (BI) (OR 0.96). After integrated orthogeriatric treatment, a significant decrease was seen in the 1-year mortality rate in the frail elderly patients with a hip fracture compared to

    Religiosity and spirituality have been associated with better survival in large epidemiologic studies. This study examined the relationship between spiritual absence and 1-year all-cause mortality in allogeneic hematopoietic stem cell transplant (HSCT) recipients. Depression and problematic compliance were examined as possible mediators of a significant spiritual absence-mortality relationship. Eighty-five adults (mean = 46.85 years old, SD = 11.90 years) undergoing evaluation for allogeneic HSCT had routine psychologie evaluation prior to HSCT admission. The Millon Behavioral Medicine Diagnostic was used to assess spiritual absence, depression, and problematic compliance, the psychosocial predictors of interest. Patient status at 1 year and survival time in days were abstracted from medical records. Cox regression analysis was used to examine the relationship between the psychosocial factors of interest and mortality after adjusting for relevant biobehavioral factors. Twenty-nine percent (n = 25) of participants died within 1 year of HSCT. After covarying for disease type, individuals with the highest spiritual absence and problematic compliance scores were significantly more likely to die 1-year post-HSCT (hazard ratio [HR] = 2.49, P = .043 and HR = 3.74, P = .029, respectively), particularly secondary to infection, sepsis, or graft-versus-host disease (GVHD) (HR = 4.56, P = .01 and HR = 5.61, P = .014), relative to those without elevations on these scales. Depression was not associated with 1-year mortality, and problematic compliance did not mediate the relationship between spiritual absence and mortality. These preliminary results suggest that both spiritual absence and problematic compliance may be associated with poorer survival following HSCT. Future research should examine these relations in a larger sample using a more comprehensive assessment of spirituality.

    Nucleotide-sequencing and multiplexed primer-extension assays have been used to quantitate the mutant-allele frequency in 14 maternal relatives, spanning three generations, from a family that is heteroplasmic for the primary Leber hereditary optic neuropathy (LHON) mutation at nucleotide 3460 of the mitochondrial genome. There was excellent agreement between the values that were obtained with the two different methods. The longitudinal study shows that the mutant-allele frequency was constant within individual family members over a sampling period of 3.5 years. Second, although there was an overall increase in the mutant-allele frequency in successive generations, segregation in the direction of the mutant allele was not invariant, and there was one instance in which there was a significant decrease in the frequency from parent to offspring. From these two sets of results, and from previous studies of heteroplasmic LHON families, we conclude that there is no evidence for a marked selective pressure that determines the replication, segregation, or transmission of primary LHON mutations to white blood cells and platelets. Instead, the mtDNA molecules are most likely to replicate and segregate under conditions of random drift at the cellular level. Finally, the pattern of transmission in this maternal lineage is compatible with a developmental bottleneck model in which the number of mitochondrial units of segregation in the female germ line is relatively small in relation to the number of mtDNA molecules within a cell. However, this is not an invariant pattern for humans, and simple models of mitochondrial gene transmission are inappropriate at the present time. 37 refs., 4 figs., 1 tab.

    A validation study was conducted to extend the matrix claim for the Nissui Compact Dry Total Count (TC), Performance Tested Method(s)(SM) (PTM) Certification No. 010404, to cooked chicken, lettuce, frozen fish, milk powder, and pasteurized whole milk. The method was originally certified by the AOAC Research Institute Performance Tested Method(s)(SM) Program for raw meat products. The Compact Dry TC is a ready-to-use dry media sheet that is rehydrated by adding 1 mL of diluted sample. A total aerobic colony count can be determined in the sample following 48 h of incubation. Matrix extension studies were conducted by Campden BRI (formerly Campden and Chorleywood Food Research Association Technology Limited), Chipping Campden, UK. Single-laboratory data were collected for cooked chicken, lettuce, frozen fish, and milk powder, whereas a multilaboratory study was conducted on pasteurized milk. Fourteen laboratories participated in the collaborative study. The Compact Dry TC was tested at two time points, 48 ± 3 h and 72 ± 3 h and compared with the current International Organization for Standardization (ISO) method at the time of the study, ISO 4833:2003 (this standard is withdrawn and has been replaced by: ISO 4833-1:2013 and ISO 4833-2:2013), Microbiology of food and animal feeding stuffs-Horizontal method for the enumeration of microorganisms-Colony-count technique at 30°C. The data were logarithmically transformed and evaluated for repeatability (plus reproducibility for pasteurized milk), RSD of repeatability (plus RSD of reproducibility for milk), r(2), and mean difference between methods with 95% confidence interval (CI). A CI outside of (-0.5 to 0.5) on the log10 mean difference was used as the criterion to establish significant statistical difference between methods. No significant differences were found between the Compact Dry TC 48 and 72 h time points, with the exception of one contamination level of cooked chicken and one contamination level of dry milk

    Estrogen receptors are present in thyroid follicular cells in normal and neoplastic tissue. We evaluated changes in total thyroid volume and volume of thyroid nodules in postmenopausal women given either hormone therapy (HT) or no treatment in a 1-year observational follow-up. We studied 33 women receiving HT and 76 women receiving no treatment, comparing total thyroid volume, thyroid nodule volume, and serum concentrations of thyroid-stimulating hormone and estradiol at baseline and 1 year of follow-up. Serum thyroid-stimulating hormone concentrations were not different between groups either at baseline or at 1 year. Estradiol rose significantly in the HT group. The final percent changes in total thyroid volume were comparable between groups (HT, 1.59 +/- 2.56%; no treatment, 1.20 +/- 2.28%). At baseline, nodules were detected in 17 (51.5%) and 33 (43.4%) of women in the HT and no treatment groups, respectively, with no statistically significant difference between groups. The final number of nodules was unchanged or reduced in 88.2% and 81.1% and increased in 11.8% and 18.9% of women in the HT and no treatment groups, respectively, with no differences between groups. Baseline volumes of thyroid nodules were 0.8 +/- 0.4 and 1.4 +/- 0.4 mL in women in the HT and no treatment groups, respectively (P = 0.4). After 1 year the volume of thyroid nodules was unchanged or reduced in 47.1% and 52.8% and increased in 52.9% and 47.2% of women in the HT and no treatment groups, respectively, with no differences between groups. Estrogen administration for 1 year did not affect thyroid volume or the number and volume of thyroid nodules in postmenopausal women.

    Risk factors for poor quality of life (QOL) after subarachnoid hemorrhage (SAH) remain poorly described. To identify the frequency and predictors of poor QOL 1 year after SAH. We studied 1-year QOL in a prospectively collected cohort of 1181 consecutively admitted SAH survivors between July 1996 and May 2013. Patient clinical, radiographic, surgical, and acute clinical course information was recorded. Reduced QOL (overall, physical, and psychosocial) at 1 year was assessed with the Sickness Impact Profile and defined as 2 SD below population-based normative Sickness Impact Profile values. Logistic regression leveraging multiple imputation to handle missing data was used to evaluate reduced QOL. Poor overall QOL was observed in 35% of patients. Multivariable analysis revealed that nonwhite ethnicity, high school education or less, history of depression, poor clinical grade (Hunt-Hess Grade ≥3), and delayed infarction were predictors of poor overall and psychosocial QOL. Poor physical QOL was additionally associated with older age, hydrocephalus, pneumonia, and sepsis. At 1 year, patients with poor QOL had increased difficulty concentrating, cognitive dysfunction, depression, and reduced activities of daily living. More than 91% of patients with poor QOL failed to fully return to work. These patients frequently received physical rehabilitation, but few received cognitive rehabilitation or emotional-behavioral support. Reduced QOL affects as many as one-third of SAH survivors 1 year after SAH. Delayed infarction is the most important in-hospital modifiable factor that affects QOL. Increased attention to cognitive and emotional difficulties after hospital discharge may help patients achieve greater QOL.

    Motor imagery (MI) is widely used to study cognitive action control. Although, the neural simulation theory assumes that MI and motor execution (ME) share many common features, the extent of similarity and whether it spreads into the preparation phase is still under investigation. Here we asked, whether an extension of physiological mental preparation has a comparable effect on MI and ME. Data were recorded using wireless functional near-infrared spectroscopy (fNIRS) in a two-stage task design where subjects were cued with or without preparatory stimuli to either execute or imagine complex sequential thumb-finger tasks. The main finding is that the extended mental preparation has a significant positive effect on oxy-hemoglobin (∆[O(2)Hb]) in response to MI, which is proportionally larger as that found in response to ME. Furthermore, fNIRS was capable to discriminate within each task whether it was preceded by preparatory stimuli or not. Transition from mental preparation to actual performance (ME or MI) was reflected by a dip of the fNIRS signal presumably related to underlying cortical processes changing between preparation and task performance. Statistically significant main effects of 'Preparation' and 'Task' showed that ∆[O(2)Hb] during preparation was preparation-specific, i.e., positively affected by the presence of preparatory stimuli, whereas during task performance ∆[O(2)Hb] was both preparation- and task-specific, i.e., additionally affected by the task mode. These results are particularly appealing from a practical point of view for making use of MI in neuroscientific applications. Especially neurorehabilitation and neural interfaces may benefit from utilizing positive interactions between mental preparation and MI performance.

    Successful integration of nutrition interventions into large-scale development programmes from nutrition-relevant sectors, such as agriculture, can address critical underlying determinants of undernutrition and enhance the coverage and effectiveness of on-going nutrition-specific activities. However, evidence on how this can be done is limited. This study examines the feasibility of delivering maternal, infant, and young child nutrition behaviour change communication through an innovative agricultural extension programme serving nutritionally vulnerable groups in rural India. The existing agriculture programme involves participatory production of low-cost videos promoting best practices and broad dissemination through village-level women’s self-help groups. For the nutrition intervention, 10 videos promoting specific maternal, infant, and young child nutrition practices were produced and disseminated in 30 villages. A range of methods was used to collect data, including in-depth interviews with project staff, frontline health workers, and self-help group members and their families; structured observations of mediated video dissemination sessions; nutrition knowledge tests with project staff and self-help group members; and a social network questionnaire to assess diffusion of promoted nutrition messages. We found the nutrition intervention to be well-received by rural communities and viewed as complementary to existing frontline health services. However, compared to agriculture, nutrition content required more time, creativity, and technical support to develop and deliver. Experimentation with promoted nutrition behaviours was high, but sharing of information from the videos with non-viewers was limited. Key lessons learned include the benefits of and need for collaboration with existing health services; continued technical support for implementing partners; engagement with local cultural norms and beliefs; empowerment of women’s group members to champion

    Multidrug-resistant (MDR) and extensively drug-resistant (XDR) tuberculosis have emerged as major global health threats. WHO recommends contact investigation in close contacts of patients with MDR and XDR tuberculosis. We aimed to assess the burden of tuberculosis disease in household contacts of such patients. We undertook a retrospective cohort study of household contacts of patients treated for MDR or XDR tuberculosis in Lima, Peru, in 1996-2003. The primary outcome was active tuberculosis in household contacts at the time the index patient began MDR tuberculosis treatment and during the 4-year follow-up. We examined whether the occurrence of active tuberculosis in the household contacts differed by resistance pattern of the index patient: either MDR or XDR tuberculosis. 693 households of index patients with MDR tuberculosis were enrolled in the study. In 48 households, the Mycobacterium tuberculosis isolate from the index patient was XDR. Of the 4503 household contacts, 117 (2·60%) had active tuberculosis at the time the index patient began MDR tuberculosis treatment-there was no difference in prevalence between XDR and MDR tuberculosis households. During the 4-year follow-up, 242 contacts developed active tuberculosis-the frequency of active tuberculosis was nearly two times higher in contacts of patients with XDR tuberculosis than it was in contacts of patients with MDR tuberculosis (hazard ratio 1·88, 95% CI 1·10-3·21). In the 359 contacts with active tuberculosis, 142 (40%) had had isolates tested for resistance against first-line drugs, of whom 129 (90·9%, 95% CI 85·0-94·6) had MDR tuberculosis. In view of the high risk of disease recorded in household contacts of patients with MDR or XDR tuberculosis, tuberculosis programmes should implement systematic household contact investigations for all patients identified as having MDR or XDR tuberculosis. If shown to have active tuberculosis, these household contacts should be suspected as having MDR

    Unlike most chronic diseases, osteoporosis treatments are generally limited to a single drug at a fixed dose and frequency. Nonetheless, no approved therapy is able to restore skeletal integrity in most osteoporotic patients and the long-term use of osteoporosis drugs is controversial. Thus, many patients are treated with the sequential use of two or more therapies. The DATA study showed that combined teriparatide and denosumab increased bone mineral density more than either drug alone. Discontinuing teriparatide and denosumab, however, results in rapidly declining bone mineral density. In this DATA-Switch study, we aimed to assess the changes in bone mineral density in postmenopausal osteoporotic women who transitioned between treatments. This randomised controlled trial (DATA-Switch) is a preplanned extension of the denosumab and teriparatide administration study (DATA), in which 94 postmenopausal osteoporotic women were randomly assigned to receive 24 months of teriparatide (20 mg daily), denosumab (60 mg every 6 months), or both drugs. In DATA-Switch, women originally assigned to teriparatide received denosumab (teriparatide to denosumab group), those originally assigned to denosumab received teriparatide (denosumab to teriparatide group), and those originally assigned to both received an additional 24 months of denosumab alone (combination to denosumab group). Bone mineral density at the spine, hip, and wrist were measured 6 months, 12 months, 18 months, and 24 months after the drug transitions as were biochemical markers of bone turnover. The primary endpoint was the percent change in posterior-anterior spine bone mineral density over 4 years. Between-group changes were assessed by one-way analysis of variance in our modified intention-to-treat population. This study is registered with ClinicalTrials.gov, number NCT00926380. Between Sept 27, 2011, and Jan 28, 2013, eligible women from the DATA study were enrolled into DATA-Switch. Of 83 potential enrollees

    Proteinuria is a common manifestation of chronic kidney disease (CKD), and there is a high incidence of CDK and its complications following renal transplantation. However, little data are available on the association between proteinuria and graft/patient survival in the paediatric transplant population. The primary aim of this study was to investigate the associations between posttransplant proteinuria and graft/patient survival in children after renal transplantation. In this retrospective study, we screened all 91 children receiving renal allografts at a single institution between 1997 and 2007. The inclusion criteria were a functioning graft at 1 year posttransplant, data availability and no recurrence of focal-segmental glomerulosclerosis. The final cohort included 75 patients. Proteinuria was considered to be pathologic if the urinary protein/creatinine ratio was >30 mg/mmol. Donor and recipient characteristics, data on proteinuria, estimated glomerular filtration rate (eGFR) and rejection episodes were analysed. The most recent of the biopsies performed during the follow-up after 1 year posttransplant were analysed separately in the proteinuric group and the non-proteinuric group. Proteinuria at 1-year posttransplant was pathologic in 35 % of patients. The 5-year graft survival rate was significantly lower in the proteinuric group than in the non-proteinuric group (77 vs. 100 %; p Proteinuria at 1 year posttransplant was associated with reduced long-term graft survival independent of other risk factors, including decreased eGFR or episodes of acute corticosensitive and corticoresistant rejection. The most frequent histologic finding in the proteinuric group was chronic rejection. There was no significant difference in the 5-year patient survival rate between the proteinuric group and the non-proteinuric group. This study emphasizes the importance of proteinuria as a prognostic factor of renal allograft survival in children.

    Introduction This prospective observational study evaluated changes in the 3-dimensional position and remodeling of the mandibular rami, condyles, and chin at splint removal and 1 year after mandibular advancement surgery. Methods Presurgery, splint removal (4–6 weeks postsurgery), and 1-year postsurgery cone-beam computed tomography scans of 27 subjects were used. Superimposition on the cranial base was used to assess positional or remodeling changes in the anatomic regions of interest. Surface distance displacements were visually displayed and quantified by 3-dimensional color maps. A 1-sample t test was used to assess the average postsurgical changes of each region of interest. The level of significance was set at 0.05. Results After antero-inferior chin displacement with surgery (mean, 6.81 ± 3.2 mm at splint removal), the average 1-year post-surgery displacement was not statistically significant (P = 0.44). Postsurgical adaptations greater than 2 mm were observed in 48% of the patients: 16% with an additional anterior-inferior displacement of the chin of 2 to 4 mm, and 4% with ≥4 mm; 20% had postero-superior movement of 2 to 4 mm, and 8% had postero-superior movement of ≥4 mm. The condyles tended to move, on average, ≤2 mm supero-posteriorly with surgery, and this small positional displacement was maintained 1 year postsurgery (right condyle, P = 0.58; left, P = 0.88). The rami exhibited outward (lateral) movements with surgery, with greater displacement of the inferior part of the rami (≥2 mm in 65% of the subjects). This torque of the ramus with surgery was stable 1 year postsurgery. Conclusions Three-dimensional assessment of skeletal changes with mandibular advancement surgery shows that nearly half of the patients have >2 mm change in chin position from splint removal to the 1-year follow-up, with approximately equal chances of anterior and posterior movement. Torque of the rami usually occurs with mandibular advancement surgery. PMID:20381760

    In general, voluminous data exists concerning burns in children, but the data focusing specially on children less than 1 year of age is sporadic. We therefore focused on examining the special features of burns in children less than 1 year of age. A retrospective study of all outpatient treated burn patients Children and Adolescents, Helsinki, Finland, from January 2005 to December 2009 was performed. During the 5-year period we identified 106 outpatient treated infants with burns, representing 15% of all pediatric burns during the study period. The majority was male and aged 9-12 months. Most of the burns occurred at home, and in most cases a caregiver was present in the injury room. Scalds were the most common type of injury followed by contact burns. The most common source of scald was from cups containing hot drink, and the most common source of contact burn was hot stoves or oven doors. Special attention needs to be targeted toward the prevention of burns in children less than 1 year of age. The majority of the injuries could have been prevented with more vigilance.

    The purpose of this study was to assess the 1-year maintenance of the efficacy of desvenlafaxine 100 mg/day (administered as desvenlafaxine succinate) established on week 12 in a 1-year, double-blind, randomized, placebo-controlled trial in postmenopausal women seeking treatment of bothersome vasomotor symptoms. Primary efficacy endpoints were changes in hot flush (HF) frequency and severity on weeks 12, 26, and 52 in an efficacy substudy population (≥50 moderate and severe HFs per week at baseline). Secondary endpoints were Greene climacteric scale, patient global impression symptom rating, and patient global impression of change scores (weeks 12, 26, and 52) for the main study efficacy population. Safety was assessed throughout the trial. The mean baseline HF frequency (efficacy substudy population, n = 365) was 12 moderate and severe HFs per day; the mean baseline severity score was 2.4. At 1 year, women treated with desvenlafaxine maintained the efficacy established on week 12. Desvenlafaxine reduced HF frequency by 7.47 moderate and severe HFs per day on week 12 (adjusted mean difference from placebo, -2.48; 95% CI, -3.47 to -1.50; P Desvenlafaxine reduced the mean severity score by 0.63 on week 12 (placebo, -0.30; P desvenlafaxine than for placebo on months 3, 6, and 12 (all P desvenlafaxine and 79% for placebo (P = 0.006). Full safety results are reported separately. The treatment efficacy of desvenlafaxine 100 mg/day achieved on week 12 in postmenopausal women with vasomotor symptoms is maintained for 1 year.

    Full Text Available This cross-sectional and 4-year longitudinal cohort study aimed to clarify how various lifestyle-related variables affect knee extension strength in elderly Japanese women. The participants were community-dwelling women (n = 575 living in the Itabashi Ward of Tokyo, Japan aged 75-85 years at baseline (in 2008 who returned for a follow-up examination 4 years later (in 2012. Maximum isometric knee extension strength in the dominant leg was measured during comprehensive medical check-ups at baseline and follow-up. Interviews with participants included questions on their history of 11 diseases and lifestyle-related factors such as physical activity as well as dietary, smoking, and drinking habits. Cross-sectional and longitudinal analyses yielded inconsistent results regarding the associations between lifestyle-related factors and knee extension strength. While going out more frequently and regular physical exercise positively affected baseline knee extension strength, they did not affect knee extension strength in the longitudinal analysis. The longitudinal analysis revealed that more frequent intake of soy products or green and yellow vegetables at baseline decreased age-related knee extension strength decline. The inconsistent results from the cross-sectional and longitudinal analyses indicate that conducting both types of analyses is crucial for researching this type of subject. The present study demonstrates that the age-related decline in muscle strength is lower in those who frequently eat soy products or green and yellow vegetables. Thus, recommending higher intake of soy products, and green and yellow vegetables for the elderly might help maintain their muscle health.

    The ability of physically restrained and anesthetized wolves to thermoregulate is lessened and could lead to reduced survival, yet no information is available about this subject. Therefore, we analyzed rectal temperatures related to survival 1 year post-capture from 173 adult (non-pup) gray wolves (Canis lupus) captured in modified foot-hold traps for radiocollaring during June–August, 1988–2011, in the Superior National Forest of northeastern Minnesota, USA. The maximum observed rectal temperature (“maxtemp,” ° F, ° C) in each wolf during capture (x = 104.0, 40.0; SD = 2.0, 1.1; min. = 95.9, 35.5; max. = 108, 42.2) was not a significant predictor of survival to 1 year post-capture. Although no weather or morphometric variable was a significant predictor of maxtemps, wolves initially anesthetized with ketamine–xylazine rather than telazol®–xylazine averaged higher maxtemps. This information does not fully address possible effects of high body temperatures related to live-capture and handling of wolves, but it does provide a useful waypoint for future assessments of this relationship and a reassurance to wildlife practitioners that the maxtemps observed in our study did not appear to affect 1-year survival.

    Many epidemiological studies have suggested that a variety of medical illnesses are associated with suicide. Investigating the time-varying pattern of medical care utilization prior to death in suicides motivated by physical illnesses would be helpful for developing suicide prevention programs for patients with physical illnesses. Suicides motivated by physical illnesses were identified by the investigator's note from the National Police Agency, which was linked to the data from the Health Insurance Review and Assessment. We investigated the time-varying patterns of medical care utilization during 1 year prior to suicide using repeated-measures data analysis after adjustment for age, gender, area of residence, and socioeconomic status. Among 1994 suicides for physical illness, 1893 (94.9%) suicides contacted any medical care services and 445 (22.3%) suicides contacted mental health care during 1 year prior to suicide. The number of medical care visits and individual medical expenditures increased as the date of suicide approached (psuicide significantly increased only in 40- to 64-year-old men (p=0.002), women suicides motivated by physical illnesses contacted medical care during 1 year prior to suicide, but many of them did not undergo psychiatric evaluation. This underscores the need for programs to provide psychosocial support to patients with physical illnesses.

    Ultrahigh energy cosmic rays carry information about their sources and the intervening medium apart from providing a beam of particles for studying certain features of high energy interactions currently inaccessible at man-made accelerators. They can at present be studied only via the extensive air showers (EAS's) they generate while passing through the Earth's atmosphere, since their fluxes are too low for the experiments of limited capability flown in balloons and satellites. The EAS is generated by a series of interactions of the primary cosmic ray and its progeny with the atmospheric nucle

    GI-cat is a Java software package that implements discovery and access services for disparate geospatial resources. An instance of GI-cat provides a single point of service for querying and accessing remote, as well as local, heterogeneous sources of geospatial information, either through standard interfaces, or taking advantage of GI-cat advanced features, such as incremental responses, query feedback, etc. GI-cat supports a number of de-iure and de-facto standards, but can also be extended to additional community catalog/inventory services, by defining appropriate mediation components. The GI-cat and the SIB-ESS-C development teams collaborated in the development of a mediator to the Siberian Earth Science System Cluster (SIB-ESS-C), a web-based infrastructure to support the communities of environmental and Earth System research in Siberia. This activity resulted in the identification of appropriate technologies and internal mechanisms supporting the development of GI-cat extensions, that are the object of this work. GI-cat is actually built up of a modular framework of SOA components, that can be variously arranged to fit the needs of a community of users. For example, a particular GI-cat instance may be configured to provide discovery functionalities onto an OGC WMS; or to adapt a THREDDS catalog to the standard OGC CSW interface; or to merge a number of CDI repositories into a single, more efficient catalog. The flexibility of GI-cat framework is achieved thanks to its design, that follows the Tree of Responsibility (ToR) pattern and the Uniform Pipe and Filter architectural style. This approach allows the building of software blocks that can be flexibly reused and composed in multiple ways. In fact, the components that make up any GI-cat configuration all implement two common interfaces (i.e. IChainNode and ICatalogService), that support chaining one component to another . Hence, it would suffice to implement those interfaces (plus an appropriate factory

    Full Text Available This paper describes a piece of classroom-centred research we did into the extensive reading practices of adult basic literacy learners. The research reported here was part of a larger research project into the 'communicational' teaching of English for beginning learners inspired by the work of Prabhu (1987. Using comics supplied by The Storyteller Group, we experimented with the Prabhu/Krashen 'acquisition' approach and extended the pedagogy through trial and error, documenting the whole process with the help of video recordings and our own notes. We present four stages in this 'reading for pleasure' course with descriptions of the pedagogy and excerpts of classroom interaction. Important outcomes of this research are the creative use of language promoted by story re-telling and the desire for ownership of books by learners once they experience ownership of the story through task-based activities on the comics.

    Terpenoid, fat-soluble antioxidant and fatty acid (FA) composition of pasture as well as those of milk and cheese from a commercial sheep flock managed under extensive mountain grazing in the east region of the Cantabrian mountain (Northern Spain) was investigated. The grazing period lasted for 2 months and ewes were at late lactation stage. Plants, feces, bulk milk and cheese samples were collected on two sampling dates. The abundance of the dominating botanical families in the mountain pasture prevailed in the sheep diet of the commercial flock. Major terpenoids and tocols in the pasture appeared as major ones in milk and cheese, whereas C18 unsaturated FAs in milk and cheese were derived from the intake of C18 polyunsaturated FAs which were prevalent in the pasture. No carotene was detected in the dairy samples but retinol (free or esterified), derived from the intake of β-carotene present in pasture plants, was found in milk and cheese.

    Iodine deficiency remains a major public health problem mainly in least-developed countries but also in many industrialized countries. The present study aimed at: (1) evaluating the status of iodine nutrition of children until 1 year in the North region of France; (2) studying risk factors for iodine deficiency; (3) evaluating relationship between iodine deficiency and thyroid disorders. This prospective study was conducted between 1st january and 31st May 2005 in the children's hospital of Lille (North of France) and all hospitalized children until the age of 1 year were enrolled. Urinary iodine assessment was obtained for 95 (83%) of the 114 infants hospitalized during the study period and TSH value was also determined in 57 (60%) of these 114 infants. Median urinary iodine concentration was 328 microg/L (range: 12-1580). Twenty-four (25%) of 95 infants had a high urinary iodine excretion (urinary iodine greater than 400 microg/L). Nineteen (20%) of the 95 infants were iodine deficient (urinary iodine less than 100 microg/L): severe iodine deficiency (less than 20 microg/L; n=5; 5%), moderate iodine deficiency (20-49 microg/L; n=6; 6%), mild iodine deficiency (50-99 microg/L; n=8; 8%). No relationship was found between iodine status and the following data: age, sex, familial thyroid disease history, term and type of delivery, nutritional status, type of feeding at inclusion, chronic disease, familial socioeconomic status. TSH value was high (greater than 5 microU/mL) in 7 (12%) of the 57 infants. Only 1 of these 7 infants was iodine deficient. Only 1 of the 19 infants with iodine deficiency had a high TSH value. Iodine status is not optimal in our population of hospitalized children until the age of 1 year. There is no clear relationship between iodine status and thyroid function.

    Full Text Available Information and communication technologies (ICTs are increasingly influencing human beings and are changing our attitudes towards these technologies. The purpose of this article is to understand the factors influencing the use of ICTs in agricultural extension through a descriptive research method. The populations were 320 individuals of agricultural Extension Workers (EWs of Isfahan province that 200 people selected as a research sample. The reliability of self-completion questionnaire according to pilot test and calculating Cronbach's alpha for four part of the instrument was 82.6 - 87.8. The results revealed that the EWs have a positive attitude toward using ICT. They mostly viewed it as a useful tool for extension, which can potentially save money and time and extension. On the ranking of principal areas of applying ICTs by EWs “typing letters/report”, “prepare and protect file on process basic agricultural and rural information”, had most usage. The main result of the study revealed that the EWs approximately use ICT quite a bit. Also, the EWs with high school diploma degree used ICT less than the EWs with MSc degree and the EWs with 5 years and less experience had higher ICT application than the EWs with 15-16 year experience.

    Cow's milk protein allergy (CMPA) is highly prevalent in infants (2-5%). It has a wide clinical spectrum, and confirmation through an oral food challenge (OFC) is relevant for its differential diagnosis. Information on this topic is scarce in Chile. To describe the demographic and clinical features of infants with suspected CMPA. A retrospective study of patients<1 year-old, treated for suspected CMPA between 2009 and 2011. Demographic data, symptoms of atopy, nutrition at the time of diagnosis, CMPA symptoms, diagnostic studies, and response to treatment were recorded. Diet response at least 4 weeks after milk modification, and clinical behavior when suspected foods were added back to the diet were considered standard diagnostic criteria. Descriptive statistics were performed using Epiinfo ™ software. The study included 106 infants, of whom, 51% male, 80% term newborns, 74% with≥1 atopic parent, and 34% with ≥1 parent/sibling with food allergy. The median age at onset of symptoms was 1.5 months (range 1.5-2m). Almost half (46%) were breast-feeding≥6m, with 15% receiving formula milk since the neonatal period, and 49% before the third month. Common symptoms were: vomiting (63%), colic (49%), and bleeding on passing stools (41%). No anaphylaxis was identified, and 61% had≥2 symptoms at debut. Only 34% were subjected to OFC. The most frequently requested tests were, test patch (43%), prick test (40%), and blood in stools (37%). 43% breast feeding with exclusion diet, 24% extensively hydrolysed formula, 26% amino acid formula, and 7% others. Demographic characteristics and risk factors were similar to those previously described in international literature. Clinical presentation was early in life, and digestive symptoms predominated. OFC was underused for diagnosis, and most of the tests requested did not change management. Copyright © 2016 Sociedad Chilena de Pediatría. Publicado por Elsevier España, S.L.U. All rights reserved.

  15. Compression-extension transition of continental crust in a subduction zone: A parametric numerical modeling study with implications on Mesozoic-Cenozoic tectonic evolution of the Cathaysia Block

    The Cathaysia Block is located in southeastern part of South China, which situates in the west Pacific subduction zone. It is thought to have undergone a compression-extension transition of the continental crust during Mesozoic-Cenozoic during the subduction of Pacific Plate beneath Eurasia-Pacific Plate, resulting in extensive magmatism, extensional basins and reactivation of fault systems. Although some mechanisms such as the trench roll-back have been generally proposed for the compression-extension transition, the timing and progress of the transition under a convergence setting remain ambiguous due to lack of suitable geological records and overprinting by later tectonic events. In this study, a numerical thermo-dynamical program was employed to evaluate how variable slab angles, thermal gradients of the lithospheres and convergence velocities would give rise to the change of crustal stress in a convergent subduction zone. Model results show that higher slab dip angle, lower convergence velocity and higher lithospheric thermal gradient facilitate the subduction process. The modeling results reveal the continental crust stress is dominated by horizontal compression during the early stage of the subduction, which could revert to a horizontal extension in the back-arc region, combing with the roll-back of the subducting slab and development of mantle upwelling. The parameters facilitating the subduction process also favor the compression-extension transition in the upper plate of the subduction zone. Such results corroborate the geology of the Cathaysia Block: the initiation of the extensional regime in the Cathaysia Block occurring was probably triggered by roll-back of the slowly subducting slab.

  18. Experimental Study of Crack Initiation and Extension Induced by Hydraulic Fracturing in a Tree-Type Borehole Array

    Directory of Open Access Journals (Sweden)

    Yiyu Lu

    2016-06-01

    Full Text Available High-pressure hydraulic fracturing technology in coal and coal bed methane mines can lead to roof and floor damage, and fracture initiation disorder that leads to a “blank area”, and other issues. A new method of hydraulic fracturing is proposed to increase the homogeneous permeability of coal in underground coalmines. Numerical and other simulation tests for different forms of a tree-type, branched borehole model are presented. The results show that the branched array causes cracks to initiate from the bottom of the array, and these extend along the direction of the adjacent boreholes. Generally, as the number of branched boreholes increases, the coal seam fracture network also increase, improving the distribution of the fracture network, making the fracturing effect better. The branched boreholes appear to reduce initiation pressure and, with increasing branches, the initiation pressure decreases. A model with four tree-type, branched boreholes leads to a reduction in initiation pressure of 69%. In terms of permeability improvement technology in underground coalmines, a branched hydraulic fracturing borehole array has the advantages of reducing initiation pressure, controlling crack initiation and extension, enhancing the fracturing effect and reducing the destruction of the roof and floor.

    Full Text Available Background The incidence rate of acute diarrheal disease in children is a health indicator, and the estimation of these data can help guide public health policies. Objectives The aim of this study was to estimate the incidence and risk factors for acute diarrheal disease in children aged 0 - 1 year. Patients and Methods An observational prospective cohort study was conducted on 210 children recruited at Hospital Nossa Senhora da Conceicao, in Tubarao, state of Santa Catarina, Brazil. Children born between July and September 2012 were followed up for 12 months. The presence of three or more liquid or loose stools during a 24-hour period was considered acute diarrhea. The categories of variables evaluated were comprised of sociodemographic characteristics (per capita income, maternal education, maternal age, access to medical care [public or private], and housing and living conditions [sanitation and hygiene, water supply, daycare attendance, and domestic animal] and characteristics of the child (gender, birth weight, and breastfeeding. Results The incidence of acute diarrhea among the 0 - 1-year-old children was 26.7 cases per 1,000 children per month. Independent risk factors for the occurrence of diarrhea were maternal age under 20 years and health care services provided by the Brazilian National Health System (SUS. Conclusions The high incidence density of diarrhea among the children recruited in this study indicates the need for educational programs directed at people who are involved in this issue.

    The overall measurement of farm level greenhouse gas (GHG) emissions in dairy production is not feasible, from either an engineering or administrative point of view. Instead, computational model systems are used to generate emission inventories, demanding a validation by measurement data. This paper tests the GHG calculation of the dairy farm-level optimization model DAIRYDYN, including methane (CH₄) from enteric fermentation and managed manure. The model involves four emission calculation procedures (indicators), differing in the aggregation level of relevant input variables. The corresponding emission factors used by the indicators range from default per cow (activity level) emissions up to emission factors based on feed intake, manure amount, and milk production intensity. For validation of the CH₄ accounting of the model, 1-year CH₄ measurements of an experimental free-stall dairy farm in Germany are compared to model simulation results. An advantage of this interdisciplinary study is given by the correspondence of the model parameterization and simulation horizon with the experimental farm's characteristics and measurement period. The results clarify that modeled emission inventories (2,898, 4,637, 4,247, and 3,600 kg CO₂-eq. cow(-1) year(-1)) lead to more or less good approximations of online measurements (average 3,845 kg CO₂-eq. cow(-1) year(-1) (±275 owing to manure management)) depending on the indicator utilized. The more farm-specific characteristics are used by the GHG indicator; the lower is the bias of the modeled emissions. Results underline that an accurate emission calculation procedure should capture differences in energy intake, owing to milk production intensity as well as manure storage time. Despite the differences between indicator estimates, the deviation of modeled GHGs using detailed indicators in DAIRYDYN from on-farm measurements is relatively low (between -6.4% and 10.5%), compared with findings from the literature.

    Full Text Available This paper examines the economic effects of investment in developing and introducing Almond Late Flowering Cultivars (ALFC in a period of 52 years from 1968 to 2020, developed in Sahand Horticultural Research Station (SHRS, using the economic surplus model and field survey data. ALFC make almond supply curve move less to the left when there is a chilling case, thus affect the economic surplus of producers and consumers. Results showed that because of ALFC, economic surplus of producers and consumers had been increased about 0.4 and 0.6 million US Dollars, respectively that the share of consumers from benefits was 58 percent. The social net present value of ALFC regarding to the cost of research and extension was about 0.1 million US Dollars. It was identified that the internal rate of return in developing and introducing of ALFC had been about 11%. The findings expressed that if the research investment in ALFC could keep the position of almond supply curve unchanged unless the weather conditions, then the economic surplus of producers and consumers would decreased 3 and 4.2 million US Dollars less annually, respectively and internal rate of return in almond research would be 33 %. Comparing the results showed that the introduction of late flowering cultivars could reduce the loss only 4 % per hectare. The results illustrated that investment in R&E of almond could make supply curve shift less in chilling situation because of decrease in cultivation cost, but it is necessary to enhance almond yield too. The findings identify that the efficiency of current system of R&E for almond is low. So it is a necessity to find ways for make better the R&E performance in Iran.

    Telomere length, a reliable predictor of disease pathogenesis, can be affected by genetics, chronic stress and health behaviors. Cross-sectionally, highly stressed postmenopausal women have shorter telomeres, but only if they are inactive. However, no studies have prospectively examined telomere length change over a short period, and if rate of attrition is affected by naturalistic factors such as stress and engagement in healthy behaviors, including diet, exercise, and sleep. Here we followed healthy women over 1 year to test if major stressors that occurred over the year predicted telomere shortening, and whether engaging in healthy behaviors during this period mitigates this effect. In 239 postmenopausal, non-smoking, disease-free women, accumulation of major life stressors across a 1-year period predicted telomere attrition over the same period-for every major life stressor that occurred during the year, there was a significantly greater decline in telomere length over the year of 35 bp (P<0.05). Yet, these effects were moderated by health behaviors (interaction B=0.19, P=0.04). Women who maintained relatively higher levels of health behaviors (1 s.d. above the mean) appeared to be protected when exposed to stress. This finding has implications for understanding malleability of telomere length, as well as expectations for possible intervention effects. This is the first study to identify predictors of telomere length change over the short period of a year.

    Full Text Available The purpose of this study was to identify predictors of grades of disability at least 1 year after stroke rehabilitation therapy. We recruited stroke patients from the inpatient rehabilitation department of a university hospital. The degree of disability was graded using the disability evaluation at least 1 year after stroke onset. Functional ability was evaluated using the Functional Independence Measure instrument on admission, on discharge from the inpatient rehabilitation program, and at the 6-month follow-up visit after discharge. Major sociodemographic, medical, and rehabilitative factors were also collected during the hospitalization period. Of the 109 patients surveyed, 64 (58.7% had severe or very severe grades of disability. The correlates of severe or very severe disability in logistic regression analyses were bilaterally affected (odds ratio, OR, 10.8, impaired orientation (OR, 3.6, and poorer functional ability at discharge (OR, 7.6. Based on the significant predictors identified, the logistic regression model correctly classified severe or very severe disability in 68.0% of subjects. The higher frequency of severe or very severe disability in this study may have been due to the relatively more severely affected stroke patient population in the inpatient rehabilitation service and the use of unique disability evaluation criteria. These results may provide information useful in planning continuous rehabilitation care and setting relevant socio-welfare policies for stroke victims.

    Using 30-day operative mortality reported with lower extremity bypass (LEB) in preoperative decision making may underestimate the actual death rate encountered before patients have truly recovered from surgery, especially in elderly, debilitated patients with significant tissue loss. Therefore, we examined preoperative, patient-level risk factors that predict survival within the first year following LEB. Using our regional quality improvement initiative in 11 hospitals in Northern New England, we studied 2306 LEB procedures performed in 2031 patients between January 2003 and December 2007. Sixty surgeons contributed to our database, and over 100 demographic and clinical variables were abstracted by trained researchers. Cox proportional hazards models were used to generate hazard ratios (HR) and surrounding 95% confidence intervals (CI) for our combined outcome measure of death occurring within the first year postoperatively. We found that within our cohort of 2306 bypass procedures, 11% of patients died within 1 year of surgery (2% prior to discharge, 9% prior to 1-year follow-up). We identified six preoperative patient characteristics associated with higher risk of death in multivariate analysis: congestive heart failure (HR 1.3, 95% CI 1.0-1.8), diabetes (HR 1.5, 95% CI 1.1-2.1), critical limb ischemia (CLI) (HR 1.7, 95% CI 1.3-2.4), lack of single-segment saphenous vein (HR 1.9, 95% CI 1.5-2/5), age over 80 (HR 2.0, 95% CI 1.5-2.7), dialysis dependence (HR 2.7, 95% CI 1.9-3.6), and emergent nature of the procedure (HR 3.4, 95% CI 1.7-6.8). While patients with no risk factors had 1-year death rates that were less than 5%: patients with three or more risk factors had a 28% chance of dying before 1 year postoperatively. When we compared risk-adjusted survival across centers, we found that one center in our region performed significantly better than expected (observed-to-expected outcome ratio 0.7, 95% CI 0.6-0.9, P = .04). Preoperative risk factors allow surgeons

    Lumbar spinal stenosis is a major public health issue. Interspinous devices implanted using minimally invasive techniques may constitute an alternative to the reference standard of bony decompression with or without intervertebral fusion. However, their indications remain unclear, due to a paucity of clinical and biomechanical data. Our objective was to evaluate the effects of four interspinous process devices implanted at L4-L5 on the intervertebral foramen surface areas at the treated and adjacent levels, in flexion and in extension. Six fresh frozen human cadaver lumbar spines (L2-sacrum) were tested on a dedicated spinal loading frame, in flexion and extension, from 0 to 10 N·m, after preparation and marking of the L3-L4, L4-L5, and L5-S1 foramina. Stereoscopic 3D images were acquired at baseline then after implantation at L4-L5 of each of the four devices (Inspace(®), Synthes; X-Stop(®), Medtronic; Wallis(®), Zimmer; and Diam(®), Medtronic). The surface areas of the three foramina of interest were computed. All four devices significantly opened the L4-L5 foramen in extension. The effects in flexion separated the devices into two categories. With the two devices characterized by fixation in the spinous processes (Wallis(®) and Diam(®)), the L4-L5 foramen opened only in extension; whereas with the other two devices (X-Stop(®) and Inspace(®)), the L4-L5 foramen opened not only in extension, but also in flexion and in the neutral position. None of the devices implanted at L4-L5 modified the size of the L3-L4 foramen. X-Stop(®) and Diam(®) closed the L5-S1 foramen in extension, whereas the other two devices had no effect at this level. Our results demonstrate that interspinous process devices modify the surface area of the interspinous foramina in vitro. Clinical studies are needed to clarify patient selection criteria for interspinous process device implantation. Level IV. Investigating an orthopaedic device. Copyright © 2015 Elsevier Masson SAS.

    With the rapidly growing number of CT examinations, the consequential radiation risk has aroused more and more attention. The average dose in each organ during CT scans can only be obtained by using Monte Carlo simulation with computational phantoms. Since children tend to have higher radiation sensitivity than adults, the radiation dose of pediatric CT examinations requires special attention and needs to be assessed accurately. So far, studies on organ doses from CT exposures for pediatric patients are still limited. In this work, a 1-year-old computational phantom was constructed. The body contour was obtained from the CT images of a 1-year-old physical phantom and the internal organs were deformed from an existing Chinese reference adult phantom. To ensure the organ locations in the 1-year-old computational phantom were consistent with those of the physical phantom, the organ locations in 1-year-old computational phantom were manually adjusted one by one, and the organ masses were adjusted to the corresponding Chinese reference values. Moreover, a CT scanner model was developed using the Monte Carlo technique and the 1-year-old computational phantom was applied to estimate organ doses derived from simulated CT exposures. As a result, a database including doses to 36 organs and tissues from 47 single axial scans was built. It has been verified by calculation that doses of axial scans are close to those of helical scans; therefore, this database could be applied to helical scans as well. Organ doses were calculated using the database and compared with those obtained from the measurements made in the physical phantom for helical scans. The differences between simulation and measurement were less than 25% for all organs. The result shows that the 1-year-old phantom developed in this work can be used to calculate organ doses in CT exposures, and the dose database provides a method for the estimation of 1-year-old patient doses in a variety of CT examinations.

    In urban environments where populations continue to rise, the need for affective stormwater management and runoff control methods is ever prevalent. Increased population growth and city expansion means greater impervious surfaces and higher rates of stormwater runoff. In well-established cities, this proves particularly difficult due to a constraining built environment and limited pervious spaces, even in cities as small as 40,000 residents. Work to reduce runoff in combined sewer systems (CSS) and municipal separated storm sewer systems (MS4) by use of best-management practices is one route currently under investigation. The Purdue University campus is making efforts to reduce their impact on the West Lafayette CSS and MS4. Green roofs are one management practice being used for runoff mitigation. Specifically, Schleman Hall, an administrative student affairs building, has a small green roof located on the second floor installed in 2008. In cooperation with Purdue Physical Facilities, monitoring and analysis for the Schleman extensive green roof at Purdue University was performed from June 2012 to December 2012. The objective was to determine the stormwater retention, output water quality and net present value for the 165 m2 roof. The results from the water balance analysis revealed retention rates on average of 58% of precipitation per rain event, where retention included soil moisture, evaporation and detention/depression storage. The water quality metrics tested were Nitrate-Nitrite (NO2-NO3), Orthophosphate (PO4), Ammonia-Ammonium ion (NH3-NH4), Sulfate (SO4), total suspended solids (TSS) and pH. The pollutant concentration and load results varied, but the pH levels from precipitation increased in all samples after passing through the substrate. SO4 and PO4 results yielded higher concentrations and loads in the green roof output than the control output and precipitation, while NO2-NO3 and NH3-NH4 yielded concentrations and loads that were reduced by the green

    The Sodium Lowering in Dialysate (SoLID) trial is an ongoing a multi-center, prospective, randomised, single-blind (assessor), controlled, parallel assignment clinical trial, enrolling 96 home and self-care hemodialysis (HD) patients from 7 centers in New Zealand. The trial will evaluate the hypothesis that lower dialysate [Na+] during HD results in lower left ventricular (LV) mass. Since it's inception, observational evidence has suggested increased mortality risk with lower dialysate [Na+], possibly due to exacerbation of intra-dialytic hypotension and subsequent myocardial micro-injury. The Myocardial Micro-injury and Cardiac Remodeling Extension Study in the Sodium Lowering In Dialysate Trial (Mac-SoLID study) aims to determine whether lower dialysate [Na+] results in (i) increased levels of high-sensitivity Troponin T (hsTnT), a well-established marker of intra-dialytic myocardial micro-injury in HD populations, and (ii) increased fixed LV segmental wall motion abnormalities, a marker of recurrent myocardial stunning and micro-injury, and (iii) detrimental changes in LV geometry due to maladaptive homeostatic mechanisms. The SoLID trial and the Mac-SoLID study are funded by the Health Research Council of New Zealand. Key exclusion criteria: patients who dialyse > 3.5 times per week, pre-dialysis serum sodium dialysate sodium 135 mM and 140 mM respectively, for 12 months. The primary outcome measure for the Mac-SOLID study is repeated measures of [hsTnT] at 0, 3, 6, 9, and 12 months. The secondary outcomes will be assessed using cardiac magnetic resonance imaging (MRI), and comprise LV segmental wall motion abnormality scores, LV mass to volume ratio and patterns of LV remodeling at 0 and 12 months. The Mac-SoLID study enhances and complements the SoLID trial. It tests whether potential gains in cardiovascular health (reduced LV mass) which low dialysate [Na+] is expected to deliver, are counteracted by deterioration in cardiovascular health through alternative

    Swine influenza (SI) is a seasonal infectious disease highly important to the world pig industry. Loss of daily weight gain, increased costs for the prevention and treatment of secondary infections are the main economic losses associated with the presence of this disease. However, some epidemiological features of SI remain quite unclear. This study focused on assessing the prevalence of swine influenza virus (SIV) infection in intensive and extensive pig herds and associating risk factors. A set of 601 blood samples of five intensive farrow-to-finish farms and 361 blood samples from 56 extensive farms were analyzed using an indirect ELISA kit CIVTEST SUIS INFLUENZA®, Hipra (Amer, Spain), in order to detect anti-SIV antibodies. In total, 24.13 % of samples from intensive herds were positive, while no positive samples were detected in extensive rearing herds. Sow and weaning piglets had the highest prevalence values. In the intensive rearing system, occurrence of reproductive disorders and exposure to recently introduced animals were positively associated with the disease occurrence in swine herds. The findings highlight the importance of sows in the epidemiology of the disease and bring information about risk factors involved in the occurrence of swine influenza in intensive herds.

    Full Text Available Abstract Background and case presentation The prone leg extension (PLE is commonly used to identify dysfunction of muscle recruitment patterns. The prone leg extension is theorized to identify proximal muscle disturbances which are a result of distal injury or dysfunction (i.e. an ankle sprain. This case study compares the trunk and hip muscle (bilateral lower erector spine, ipsilateral hamstring and ipsilateral gluteus maximus timing during a PLE of a 27 year old female runner during a healthy state (pre ankle sprain and 2 and 8 weeks post ankle sprain. Results and discussion The gluteus maximus muscle onsets at 8 weeks post injury appeared to occur earlier compared with 2 weeks post injury. The Right Erector Spinae at 8 weeks post injury was also active earlier compared with the participant's non-injured state. A large degree of variability can be noted within trials on the same day for all muscle groups. Conclusion An acute ankle injury did not result in a delay in gluteus maximus muscle activation. The utility of the prone leg extension as a clinical and functional test is questionable due to the normal variability seen during the test and our current inability to determine what is normal and what is dysfunctional.

  14. BDNF mediates improvements in executive function following a 1-year exercise intervention

    Full Text Available Executive function declines with age, but engaging in aerobic exercise may attenuate decline. One mechanism by which aerobic exercise may preserve executive function is through the up-regulation of brain-derived neurotropic factor (BDNF, which also declines with age. The present study examined BDNF as a mediator of the effects of a 1-year walking intervention on executive function in 90 older adults (mean age = 66.82. Participants were randomized to a stretching and toning control group or a moderate intensity walking intervention group. BDNF serum levels and performance on a task-switching paradigm were collected at baseline and follow-up. We found that age moderated the effect of intervention group on changes in BDNF levels, with those in the highest age quartile showing the greatest increase in BDNF after 1-year of moderate intensity walking exercise (p = .036. The mediation analyses revealed that BDNF mediated the effect of the intervention on task-switch accuracy, but did so as a function of age, such that exercise-induced changes in BDNF mediated the effect of exercise on task-switch performance only for individuals over the age of 71. These results demonstrate that both age and BDNF serum levels are important factors to consider when investigating the mechanisms by which exercise interventions influence cognitive outcomes, particularly in elderly populations.

Sources of data for health and service use were MCO claims. Mortality was based on reports to the MCO from the Centers for Medicare & Medicaid Services; morbidity was measured using adjusted clinical groups case-mix methods derived from diagnoses in ambulatory and hospital claims data. Mortality in the year following Hurricane Katrina was not significantly elevated (4.3% before vs 4.9% after the hurricane). However, overall morbidity increased by 12.6% (P Hurricane Katrina on this vulnerable population. Although quick rebuilding of the provider network may have attenuated more severe health outcomes for this managed care population, new policies must be introduced to deal with the health consequences of a major disaster.

  16. Overstretching of a 30 bp DNA duplex studied with steered molecular dynamics simulation: Effects of structural defects on structure and force-extension relation

    2009-11-01

    Single-molecule experiments on polymeric DNA show that the molecule can be overstretched at nearly constant force by about 70% beyond its relaxed contour length. In this publication we use steered molecular dynamics (MD) simulation to study the effect of structural defects on force-extension curves and structures at high elongation in a 30 base pair duplex pulled by its torsionally unconstrained 5' -5' ends. The defect-free duplex shows a plateau in the force-extension curve at 120pN in which large segments with inclined and paired bases (“S-DNA”) near both ends of the duplex coexist with a central B-type segment separated from the former by small denaturation bubbles. In the presence of a base mismatch or a nick, force-extension curves are very similar to the ones of the defect-free duplex. For the duplex with a base mismatch, S-type segments with highly inclined base pairs are not observed; rather, the overstretched duplex consists of B-type segments separated by denaturation bubbles. The nicked duplex evolves, via a two-step transition, into a two-domain structure characterized by a large S-type segment coexisting with several short S-type segments which are separated by short denaturation bubbles. Our results suggest that in the presence of nicks the force-extension curve of highly elongated duplex DNA might reflect locally highly inhomogeneous stretching.

  18. Type Safe Extensible Programming

    2009-10-01

    Software products evolve over time. Sometimes they evolve by adding new features, and sometimes by either fixing bugs or replacing outdated implementations with new ones. When software engineers fail to anticipate such evolution during development, they will eventually be forced to re-architect or re-build from scratch. Therefore, it has been common practice to prepare for changes so that software products are extensible over their lifetimes. However, making software extensible is challenging because it is difficult to anticipate successive changes and to provide adequate abstraction mechanisms over potential changes. Such extensibility mechanisms, furthermore, should not compromise any existing functionality during extension. Software engineers would benefit from a tool that provides a way to add extensions in a reliable way. It is natural to expect programming languages to serve this role. Extensible programming is one effort to address these issues. In this thesis, we present type safe extensible programming using the MLPolyR language. MLPolyR is an ML-like functional language whose type system provides type-safe extensibility mechanisms at several levels. After presenting the language, we will show how these extensibility mechanisms can be put to good use in the context of product line engineering. Product line engineering is an emerging software engineering paradigm that aims to manage variations, which originate from successive changes in software.

    In an attempt to rationalize conflicting sets of data from earlier studies, groups of Type A- and Type B-classified university students were asked to respond to a sleep habits questionnaire that included the items of the Coren Insomnia Scale. As was the case in two earlier studies, we found significant but weak evidence from the Coren scale only that Type A-scoring students experience more sleep problems than Type B scorers. We also found, as in a recent study, a sharp increase in sleep problems among all the students sampled from the frequencies reported by similar groups in 1982.

    2016-06-01

    Full Text Available Concerns have been raised about the quality of reporting in nutritional epidemiology. Research reporting guidelines such as the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE statement can improve quality of reporting in observational studies. Herein, we propose recommendations for reporting nutritional epidemiology and dietary assessment research by extending the STROBE statement into Strengthening the Reporting of Observational Studies in Epidemiology-Nutritional Epidemiology (STROBE-nut.Recommendations for the reporting of nutritional epidemiology and dietary assessment research were developed following a systematic and consultative process, coordinated by a multidisciplinary group of 21 experts. Consensus on reporting guidelines was reached through a three-round Delphi consultation process with 53 external experts. In total, 24 recommendations for nutritional epidemiology were added to the STROBE checklist.When used appropriately, reporting guidelines for nutritional epidemiology can contribute to improve reporting of observational studies with a focus on diet and health.

  8. Extensive Field Survey, Laboratory and Greenhouse Studies Reveal Complex Nature of Pseudomonas syringae-Associated Hazelnut Decline in Central Italy.

    2016-01-01

    Pseudomonas avellanae (Pav) has been reported as the causal agent of bacterial decline and bacterial canker of hazelnut in Italy and Greece, respectively. Both hazelnut diseases were reported to be similar in terms of symptoms, severity and persistence. In this study, we found that both symptomatic and asymptomatic trees in the field were colonized by Pav. Multilocus Sequence Typing (MLST) analysis showed that Pav strains isolated during this study in Italy belong to the P. syringae phylogroup 1 and they are closely related to Pav strains previously isolated in Greece from hazelnut bacterial canker. On the other hand, strains isolated in earlier studies from hazelnut decline in Italy belong to both phylogroup 1 and 2 of P. syringae. Both phylogroup 1 strains of P. syringae from Greece and Italy are different than strains isolated in this study in terms of their capacity to excrete fluorescent pigments on different media. Despite the same plant genotype and cropping practices adopted, the incidence of hazelnut decline ranged from nearly 0 to 91% across our study sites. No disease developed on plants inoculated with Pav through wounding while leaf scar inoculations produced only mild disease symptoms. Based on our results and the previously reported correlation between pedo-climatic conditions and hazelnut decline, we conclude that hazelnut decline in central Italy could be incited by a combination of predisposing (adverse pedo-climatic conditions) and contributing factors (Pav). Because this is a true decline different from "bacterial canker" described in Greece, we refer to it as hazelnut decline (HD).

    1996-07-10

    The Savannah River Technology Center is evaluating new field sampling methodologies to more easily determine concentrations of radionuclides in aqueous systems. One methodology studied makes use of 3M EmporeTM disks. The disks are composed of selective resins embedded in a Teflon support. The disks remove the ion of interest from aqueous solutions when the solution is passed through the disk. The disk can then be counted directly to quantify the isotope of interest. Four types of disks were studied during this work: for the extraction of technetium (two types), cesium, plutonium, and strontium. A sampler has been developed for automated, unattended, in situ use of the EmporeTM disks.

    2016-04-01

    Our novel models for fluid's variable physical properties are improved and reported systematically in this work for enhancement of theoretical and practical value on study of convection heat and mass transfer. It consists of three models, namely (1) temperature parameter model, (2) polynomial model, and (3) weighted-sum model, respectively for treatment of temperature-dependent physical properties of gases, temperature-dependent physical properties of liquids, and concentration- and temperature-dependent physical properties of vapour-gas mixture. Two related components are proposed, and involved in each model for fluid's variable physical properties. They are basic physic property equations and theoretical similarity equations on physical property factors. The former, as the foundation of the latter, is based on the typical experimental data and physical analysis. The latter is built up by similarity analysis and mathematical derivation based on the former basic physical properties equations. These models are available for smooth simulation and treatment of fluid's variable physical properties for assurance of theoretical and practical value of study on convection of heat and mass transfer. Especially, so far, there has been lack of available study on heat and mass transfer of film condensation convection of vapour-gas mixture, and the wrong heat transfer results existed in widespread studies on the related research topics, due to ignorance of proper consideration of the concentration- and temperature-dependent physical properties of vapour-gas mixture. For resolving such difficult issues, the present novel physical property models have their special advantages.

    Objective:To explore the characteristic of the impairment of cognitive function in patients with bipolar I disorder(BD-I). Method:Sixty-six euthymic patients with BD-I and 66 healthy-matched con-trols were cognitively assessed twice over a 1-year follow-up. The patients were in euthymic during the both eval-uations. Cognitive assessment were performed by using digit symbol,digit span,trail making test( TMT)and Wisconsin card sorting test(WSCT). Results:①The results of digit symbol,digit span,TMT and WSCT were significantly poorer in BD-I patients than in normal controls(all P ﹤ 0. 01). Such deficits were maintained over a 1-year period(P ﹥ 0. 02). ②In BD-I patients,digit span,TMT-A and digit symbol were significantly correlated with duration of illness(P ﹤ 0. 02 or P ﹤ 0. 01). Digit forward,TMT-A and digit symbol were significantly corre-lated with current job situation(P ﹤ 0. 02 or P ﹤ 0. 01). None of the indexes of cognitive function were signifi-cantly correlated with length of euthymia or the age of onset(P ﹥ 0. 02).

    This automation impact study of Army training management (TM) was performed for the Army Development and Employment Agency (ADEA) and the Combined Arms Training Activity (CATA) by the Battelle Human Affairs Research Centers and the Pacific Northwest Laboratory. The primary objective of the study was to provide the Army with information concerning the potential costs and savings associated with automating the TM process. This study expands the sample of units surveyed in Phase I of the automation impact effort (Sanquist et al., 1988), and presents data concerning installation resource management in relation to TM. The structured interview employed in Phase I was adapted to a self-administered survey. The data collected were compatible with that of Phase I, and both were combined for analysis. Three US sites, one reserve division, one National Guard division, and one unit in the active component outside the continental US (OCONUS) (referred to in this report as forward deployed) were surveyed. The total sample size was 459, of which 337 respondents contributed the most detailed data. 20 figs., 62 tabs.

  7. Homology models of human gamma-crystallins: structural study of the extensive charge network in gamma-crystallins.

    2003-01-17

    The lens is composed of highly stable and long-lived proteins, the crystallins which are divided into alpha-, beta-, and gamma-crystallins. Human gamma-crystallins belong to the betagamma superfamily. A large number of gamma-crystallins have been sequenced and have been found to share remarkable sequence homology with each other. Some of the gamma-crystallins from various sources have also been elucidated structurally by X-ray crystallographic or NMR spectroscopic experiments. Their three-dimensional structures are also similar having consisted of two domains each possessing two Greek key motifs. In this study we have constructed the comparative or homology models of the four major human gamma-crystallins, gammaA-,gammaB-, gammaC-, and gammaD-crystallins and studied the charge network in these crystallins. Despite an overall structural similarity between these crystallins, differences in the ion pair formation do exist which is partly due to the differences in their primary sequence and partly due to the structural orientation of the neighboring amino acids. In this study, we present an elaborate analysis of these charged interactions and their formation or loss with respect to the structural changes.

    Laschober, Tanja C; de Tormes Eby, Lillian Turner

    2013-07-01

    The main goals of the current study were to investigate whether there are linear or curvilinear relationships between substance use disorder counselors' job performance and actual turnover after 1 year utilizing four indicators of job performance and three turnover statuses (voluntary, involuntary, and no turnover as the reference group). Using longitudinal data from 440 matched counselor-clinical supervisor dyads, results indicate that overall, counselors with lower job performance are more likely to turn over voluntarily and involuntarily than not to turn over. Further, one of the job performance measures shows a significant curvilinear effect. We conclude that the negative consequences often assumed to be "caused" by counselor turnover may be overstated because those who leave both voluntarily and involuntarily demonstrate generally lower performance than those who remain employed at their treatment program.

    BACKGROUND: Coronary computed tomographic angiography (CTA) plus estimation of fractional flow reserve using CTA (FFRCT) safely and effectively guides initial care over 90 days in patients with stable chest pain. Longer-term outcomes are unknown. OBJECTIVES: The study sought to determine the 1-year...... clinical, economic, and quality-of-life (QOL) outcomes of using FFRCT instead of usual care. METHODS: Consecutive patients with stable, new onset chest pain were managed by either usual testing (n = 287) or CTA (n = 297) with selective FFRCT (submitted in 201, analyzed in 177); 581 of 584 (99.5%) completed...... events were infrequent, with 2 in each arm of the planned invasive group and 1 in the planned noninvasive cohort (usual care strategy). In the planned invasive stratum, mean costs were 33% lower with CTA and selective FFRCT ($8,127 vs. $12,145 usual care; p

    The present study addresses the consequences of cognitive disturbances on symptomatic outcome. Fifty-three first-episode schizophrenics were reassessed (n = 32) 1 year after admission. Simple regression analyses revealed that several self-perceived cognitive deficits at baseline as measured with the Frankfurt Complaint Questionnaire significantly predicted increased Brief Psychiatric Rating Scale global scores at follow-up (p = 0.05 to p = 0.005). A stepwise regression analysis proved memory dysfunction to be the strongest predictor of symptomatic worsening (p = 0.005). It is suggested that the exploration and treatment of neuropsychological deficits in schizophrenia is of great clinical importance with regard to its impact on both functional and symptomatic outcome in schizophrenia.

    We measured IgA and IgG antibodies to pertussis toxin (PT) and filamentous hemagglutinin (FHA) in sera from 203 1-year-old children who had received one to three doses of a monocomponent PT toxoid vaccine. Ten children (5%) had IgA antibody to PT indicating recent infection; seven of these children...... had received three doses of vaccine. PT IgA responders did not have significantly longer coughing episodes than PT IgA non-responders. Since an IgA antibody response occurs in only approximately 50% of infected children, the actual infection rate in our cohort is estimated to approximately 10......%. The apparent high Bordetella pertussis infection rate in Danish infants suggests that the monocomponent PT toxoid vaccine used in Denmark has limited efficacy against B. pertussis infection. A prospective immunization study comparing a multi-component vaccine with the present monocomponent PT toxoid vaccine...

    Full Text Available Fish culture economics and extension was reviewed to enable fish culturist plan effectively before involved in fish culture and practices. The cost and benefits of fish culture need be known before participation in the business. There is need for cross-link between research and the fishing community. Prior to introduction of any new innovation in fisheries extension and evaluation of such programmers, the agency responsible for such exercise should have full knowledge of the existing farming practice/techniques and the reasons behind them. In assessing or evaluating the impact of any new techniques or programmers, consideration should be given to such factors as natural conditions, local infrastructures, socio cultural setting, farmers’ production aims and labor economics. The study reviews the types of feasibility study, a typical feasibility study and report on a fish farm project and detail analysis of culture extension to enable fish culturist plan effectively before involved in fish culture and practices.

    The present comparative performance study has established that rocket-based combined cycle (RBCC) propulsion systems, when incorporated by essentially axisymmetric SSTO launch vehicle configurations whose conical forebody maximizes both capture-area ratio and total capture area, are capable of furnishing payload-delivery capabilities superior to those of most multistage, all-rocket launchers. Airbreathing thrust augmentation in the rocket-ejector mode of an RBCC powerplant is noted to make a major contribution to final payload capability, by comparison to nonair-augmented rocket engine propulsion systems.

    AOAC Official Method(SM) 2005.06 for the determination of saxitoxin (STX)-group toxins in shellfish by LC with fluorescence detection with precolumn oxidation was previously validated and adopted First Action following a collaborative study. However, the method was not validated for all key STX-group toxins, and procedures to quantify some of them were not provided. With more STX-group toxin standards commercially available and modifications to procedures, it was possible to overcome some of these difficulties. The European Union Reference Laboratory for Marine Biotoxins conducted an interlaboratory exercise to extend AOAC Official Method 2005.06 validation for dc-GTX2,3 and to compile precision data for several STX-group toxins. This paper reports the study design and the results obtained. The performance characteristics for dc-GTX2,3 (intralaboratory and interlaboratory precision, recovery, and theoretical quantification limit) were evaluated. The mean recoveries obtained for dc-GTX2,3 were, in general, low (53.1-58.6%). The RSD for reproducibility (RSD(r)%) for dc-GTX2,3 in all samples ranged from 28.2 to 45.7%, and HorRat values ranged from 1.5 to 2.8. The article also describes a hydrolysis protocol to convert GTX6 to NEO, which has been proven to be useful for the quantification of GTX6 while the GTX6 standard is not available. The
