This study helps to better understand the need and trend in presbyopic add power in the aging society. Distribution and progression of presbyopic add power in East Asian population is largely unknown. Prospective cohort study. About 303 participants from a population-based study of residents aged 35 years and older in Guangzhou, China. Visual acuity (VA) test and non-cycloplegic automated refraction were performed at baseline in 2008 and the 6-year follow-up per standardized protocol. Participants with presenting near VA ≤ 20/40 underwent distance subjective refraction and add power measurement by increasing plus lens at a standard distance of 40 cm at each visit. Add power at baseline and follow-ups. Mean (standard deviation) age of the study participants was 57.6 (11.1) years and 50.2% were female. The mean add power at baseline was 1.43, 1.73, 2.03 and 2.20 diopters (D) for individuals in the age groups of 35-44, 45-54, 55-64 and 65+ years, respectively. Participants with older age and lower educational level had significantly higher add power requirements (P < 0.001). The overall 6-year increase in add power was 0.15D (95% CI: 0.06 to 0.25), and was smaller in myopic subjects (P = 0.03). Baseline age and add power, but not changes in biometric factors, were associated with longitudinal change in add power (P < 0.001). Distribution and progression of add power in Chinese was different from that previously suggested by Caucasian studies. More studies are needed to establish up-to-date age-related add power prescription norms for population of different ethnicities. © 2018 Royal Australian and New Zealand College of Ophthalmologists.

1993-01-01

Elastic fibers are important components of the connective tissue that attaches the articular disk of the craniomandibular joint (CMJ) to the skull and mandible. Biopsies of the articular disk proper and bilaminar zone (BZ) tissues from patients with anterior disk displacement (ADD) have shown previously that there is a marked loss of elastic fibers. In the present study, the effects of inducing ADD on the elastic fibers in the rabbit CMJ disk proper, BZ and condylar cartilage were investigated. The right CMJ was exposed surgically and the discal attachments were severed except for the BZ attachments. Then, the disk was displaced anteriorly and sutured to the zygomatic arch. The CMJs were removed after 1, 2 or 6 weeks and processed for histochemical demonstration of elastic fibers. The results showed osteoarthritic changes following ADD, and a significant decrease in the number of the elastic fibers in the disk proper and BZ. The remaining elastic fibers were abnormal in their appearance and orientation. In addition, ADD led to the appearance of fine elastic fibers among the chondrocytes in the hyaline cartilage of the condyle that were not present in the cartilage of the control condyle. We conclude that induced ADD can lead to a significant loss of elastic fibers in the articular disk, and result in the appearance of elastic fibers within the cartilage of the mandibular condyle.

2013-11-01

Lacosamide is approved as adjunctive therapy for focal epilepsies. The number of antiepileptic drugs (AEDs) tried is associated with prognosis. This multicenter, retrospective, observational study (LACO-EXP) in Spain in 500 adult patients with focal epilepsies examined the efficacy and tolerability of add-on lacosamide. Factors associated with better efficacy/tolerability were analyzed. After 12months, the responder rate (≥50% reduction in seizure frequency) was 57.1%, and the seizure-free rate was 14.9%. Efficacy was better when lacosamide was the first or second add-on AED, although there was a small chance to be seizure-free even for patients who had received ≤10 prior AEDs. The mechanism of action of concomitant AEDs is important in all the stages, but differences are smaller in the early stages. Lacosamide was generally well tolerated. A slower dosage-titration schedule was associated with a lower adverse event rate. Further investigation of the timing of initiation of lacosamide add-on therapy and ideal combinations of AEDs is required. © 2013.

Cells contain a multitude of protein complexes whose subunits interact with high specificity. However, the number of different protein folds and interface geometries found in nature is limited. This raises the question of how protein-protein interaction specificity is achieved on the structural level and how the formation of nonphysiological complexes is avoided. Here, we describe structural elements called interface add-ons that fulfill this function and elucidate their role for the diversification of protein-protein interactions during evolution. We identified interface add-ons in 10% of a representative set of bacterial, heteromeric protein complexes. The importance of interface add-ons for protein-protein interaction specificity is demonstrated by an exemplary experimental characterization of over 30 cognate and hybrid glutamine amidotransferase complexes in combination with comprehensive genetic profiling and protein design. Moreover, growth experiments showed that the lack of interface add-ons can lead to physiologically harmful cross-talk between essential biosynthetic pathways. In sum, our complementary in silico, in vitro, and in vivo analysis argues that interface add-ons are a practical and widespread evolutionary strategy to prevent the formation of nonphysiological complexes by specializing protein-protein interactions.

Sensitivity analysis of add-on price estimate for select silicon wafering technologies

NASA Technical Reports Server (NTRS)

Mokashi, A. R.

1982-01-01

The cost of producing wafers from silicon ingots is a major component of the add-on price of silicon sheet. Economic analyses of the add-on price estimates and their sensitivity internal-diameter (ID) sawing, multiblade slurry (MBS) sawing and fixed-abrasive slicing technique (FAST) are presented. Interim price estimation guidelines (IPEG) are used for estimating a process add-on price. Sensitivity analysis of price is performed with respect to cost parameters such as equipment, space, direct labor, materials (blade life) and utilities, and the production parameters such as slicing rate, slices per centimeter and process yield, using a computer program specifically developed to do sensitivity analysis with IPEG. The results aid in identifying the important cost parameters and assist in deciding the direction of technology development efforts.

Chow, M F; Yusop, Z; Shirazi, S M

2013-10-01

Information on the pollution level and the influence of hydrologic regime on the stormwater pollutant loading in tropical urban areas are still scarce. More local data are still required because rainfall and runoff generation processes in tropical environment are very different from the temperate regions. This study investigated the extent of urban runoff pollution in residential, commercial, and industrial catchments in the south of Peninsular Malaysia. Stormwater samples and flow rate data were collected from 51 storm events. Samples were analyzed for total suspended solids, 5-day biochemical oxygen demand, chemical oxygen demand, oil and grease (O&G), nitrate nitrogen (NO3-N), nitrite nitrogen, ammonia nitrogen, soluble reactive phosphorus, total phosphorus (TP), and zinc (Zn). It was found that the event mean concentrations (EMCs) of pollutants varied greatly between storm characteristics and land uses. The results revealed that site EMCs for residential catchment were lower than the published data but higher for the commercial and industrial catchments. All rainfall variables were negatively correlated with EMCs of most pollutants except for antecedent dry days (ADD). This study reinforced the earlier findings on the importance of ADD for causing greater EMC values with exceptions for O&G, NO3-N, TP, and Zn. In contrast, the pollutant loadings are influenced primarily by rainfall depth, mean intensity, and max 5-min intensity in all the three catchments. Overall, ADD is an important variable in multiple linear regression models for predicting the EMC values in the tropical urban catchments.

Blood pressure and lipid profile are important determinants of cardiovascular risk in patients with type 2 diabetes mellitus (T2DM). To identify the pleiotropic effects of vildagliptin other than blood glucose lowering effect, a retrospective study was conducted in 128 patients with T2DM treated with vildagliptin 50 mg twice daily. The patients were separated into two groups: patients who were initiated with vildagliptin as monotherapy or add-on therapy (add-on group, n = 66) and patients who were switched from sitagliptin 100 mg once daily to vildagliptin (switching group, n = 62). Hemoglobin A1c (HbA1c), body mass index (BMI), systolic/diastolic blood pressure, lipid profiles, and uric acid (UA) at 3, 6, and 12 months of vildagliptin therapy were compared with those at baseline in each group. At baseline, there were no significant differences in HbA1c, BMI, blood pressures, lipid profiles, and UA levels between the two groups. After vildagliptin initiation, HbA1c decreased significantly but BMI and blood pressure did not change in both groups. Only in the add-on group, total cholesterol and low density lipoprotein cholesterol decreased significantly from baseline to 3, 6, and 12 months. On the other hand, triglyceride and high-density lipoprotein cholesterol did not change in both groups. Serum UA levels decreased only in the switching group from baseline to 3, 6, and 12 months. These results indicate that vildagliptin add-on treatment may have beneficial effects on lipid profiles, and switching from sitagliptin to vildagliptin reduces UA in patients with T2DM; these are important findings linked to the beneficial effects of vildagliptin on lipid and UA metabolisms in the treatment of T2DM.

The aim was to assess patient-reported outcomes (PROs) in patients with rheumatoid arthritis (RA) treated with filgotinib during two phase 2b, 24-week, randomized, placebo-controlled studies. Patients with moderate-to-severe active RA and an inadequate response to methotrexate (MTX) were randomized to daily placebo or filgotinib 50 mg, 100 mg, or 200 mg as add-on therapy to MTX (NCT01888874) or as monotherapy (NCT01894516). At week 12, nonresponders receiving filgotinib 50 mg in both studies or placebo in the add-on study, and all patients receiving placebo as monotherapy, were re-assigned to filgotinib 100 mg. PROs were measured using the Health Assessment Questionnaire - Disability Index (HAQ-DI) including Patient Pain assessed by visual analog scale, and the Patient Global Assessment of Disease Activity (Patient Global), the Functional Assessment of Chronic Illness Therapy (FACIT)-Fatigue Scale (Version 4), and the 36-Item Short Form Health Survey (SF-36). At week 12, improvements in all PROs, apart from the SF-36 mental component in the add-on study, were statistically better with filgotinib than placebo; some improvements were noted as early as the first assessment time point (week 1 or week 4). Filgotinib improved HAQ-DI by 0.58-0.84 points, FACIT-Fatigue by 6.9-11.4 points, Patient Global by 25.2-35.6 mm, and Pain by 24.2-37.9 mm; scores were maintained or improved to week 24. Across all PROs, more patients achieved minimal clinically important differences and normative values with filgotinib 200 mg than placebo. Patients re-assigned to filgotinib 100 mg at week 12 experienced improvements in PROs between weeks 12 to 24. Filgotinib as MTX add-on therapy or as monotherapy demonstrated rapid and sustained (to 24 weeks) improvements in health-related quality of life and functional status in patients with active RA. MTX add-on study: ClinicalTrials.gov , NCT01888874 . Registered on 28 June 2013. Monotherapy study: ClinicalTrials.gov , NCT01894516 . Registered on 10 July 2013.

Voluntary sodium intake during effort in hot environments

Sohar, E.; Adar, R.; Hershco, A.

1982-01-01

The factors that influence the amount of salt that a person adds to his food at mealtime, and the part played by the general requirement for salt in the daily diet stemming from the coluntary input of salt are studied. Careful measurements of salt intake and outflow were performed on ten marchers in a high temperature environment who were given individual salt shakers that were weighed before and after each meal. Some marchers were told to add salt to their meals on specific days. No parallelity was found between the voluntary sodium intake and the general sodium intake, the excretion of sodium in the urine or the environmental heat stress. Individual food habit was found to be the most important factor.

Gut microbiota studies on diverse animals facilitate our understanding of the general principles governing microbiota-host interactions. The honey bee adds a relevant study system due to the simplicity and experimental tractability of its gut microbiota, but also because bees are important pollinators that suffer from population declines worldwide. The use of gnotobiotic bees combined with genetic tools, 'omics' analysis, and experimental microbiology has recently provided important insights about the impact of the microbiota on bee health and the general functioning of gut ecosystems.

The role of pairing an anesthesiology rotation with the general surgery clerkship: positive impact on surgical and perioperative education

PubMed Central

2018-01-01

Background The use of an anesthesiology rotation in the realm of surgical education is not very well studied. Several studies show the importance of an anesthesiology rotation in the grand scheme of undergraduate medical education. However, its importance in perioperative medicine and surgical education is not very well understood. This study attempts to look at this relationship and determine whether or not a temporal relationship between this anesthesiology rotation and a surgical rotation is important. Methods I used an online survey tool to survey medical students who took the anesthesiology rotation (required rotation) in 2014 and 2015 (when rotation was coupled to surgical rotation) and compared those data to the data of students who took the rotation in 2016 (when the rotation was not coupled to surgery). I asked several questions looking at the importance of the anesthesiology rotation to surgical education and to perioperative medicine. Results Having a required anesthesiology rotation appears to add value to the general surgery rotation in undergraduate medical education. Furthermore, when this rotation is paired with the general surgery rotation, it appears that the students learn more about perioperative medicine than when the rotation is paired with other “advanced” rotation. Conclusion The pairing of anesthesiology with a general surgery rotation does indeed improve the perioperative medicine education and knowledge of students. Students appreciate having a week of anesthesiology with the surgical rotation, and they note that it adds value to the general surgery rotation. PMID:29445309

Imepitoin was tested as a combination treatment with phenobarbital in an open-label mono-centre cohort study in dogs with drug-resistant epilepsy. Diagnosis of idiopathic epilepsy was based on clinical findings, magnetic resonance imaging and cerebrospinal fluid analysis. Three cohorts were treated. In cohort A, dogs not responding to phenobarbital with or without established add-on treatment of potassium bromide or levetiracetam were treated add-on with imepitoin, starting at 10 mg/kg BID, with titration allowed to 30 mg/kg BID. In cohort B, the only difference to cohort A was that the starting dose of imepitoin was reduced to 5 mg/kg BID. In cohort C, animals not responding to imepitoin at >20 mg/kg BID were treated with phenobarbital add-on starting at 0.5 mg/kg BID. The add-on treatment resulted in a reduction in monthly seizure frequency (MSF) in all three cohorts. A reduction of ≥50% was obtained in 36-42% of all animals, without significant difference between cohorts. The lower starting dose of 5 mg/kg BID imepitoin was better tolerated, and an up-titration to on average of 15 mg/kg BID was sufficient in cohort A and B. In cohort C, a mean add-on dose of 1.5 mg/kg BID phenobarbital was sufficient to achieve a clinically meaningful effect. Six dogs developed a clinically meaningful increase in MSF of ≥ 50%, mostly in cohort A. Neither imepitoin nor phenobarbital add-on treatment was capable of suppressing cluster seizure activity, making cluster seizure activity an important predictor for drug-resistance. A combination treatment of imepitoin and phenobarbital is a useful treatment option for a subpopulation of dogs with drug-resistant epilepsy, a low starting dose with 5 mg/kg BID is recommended.

2018-01-01

There is insufficient evidence to guide decisions concerning how long anti-dementia drug (ADD) regimens should be maintained in severe Alzheimer's disease (AD). We investigated whether patients with extremely severe AD who were already receiving donepezil or memantine benefited from continuing treatment. In this randomized and rater-blinded trial, 65 AD patients with a Mini-Mental State Examination score from 0 to 5 and a score of 6c or worse on Functional Assessment Staging were randomly assigned to an ADD-continuation group (N = 30) or an ADD-discontinuation group (N = 35). The current use of donepezil or memantine was maintained for 12 weeks in the ADD-continuation group and was discontinued after baseline in the ADD-discontinuation group. Efficacy measures were obtained at baseline and 12 weeks. The primary efficacy variable was the change from baseline to the end of the study in Baylor Profound Mental State Examination (BPMSE) scores. The change in the BPMSE from baseline to the end of the study in the ADD-continuation group (a 0.4-point improvement) was not equivalent to that in the ADD-discontinuation group (a 0.5-point decline), as determined by two one-sided tests of equivalence. Study withdrawals due to adverse events (11.4% versus 6.7%) were more frequent in the ADD-discontinuation group than in the ADD-continuation group. Continued treatment with donepezil or memantine seems unequal and might be superior to withdrawal of the drugs in terms of the effects on global cognition in patients with extremely severe AD. Current Controlled Trials number: KCT0000874 (CRIS).

This brief discusses the policy implications of a research study commissioned by Health Workforce Australia (HWA) within its health workforce innovation and reform work program. The project explored conceptually complex and operationally problematic concepts related to developing a whole-of-workforce competency-based education and training and competency-based career framework for the Australian health workforce and culminated with the production of three reports published by HWA. The project raised important queries as to whether such a concept is desirable, feasible or implementable - in short what is the potential value add and is it achievable? In setting the scene for discussion, the foundation of the project's genesis and focus of the study are highlighted. A summary of key definitions related to competency-based education and training frameworks and competency-based career frameworks are provided to further readers' commonality of understanding. The nature of the problem to be solved is explored and the potential value-add for the Australian health workforce and its key constituents proposed. The paper concludes by discussing relevance and feasibility issues within Australia's current and changing healthcare context along with the essential steps and implementation realities that would need to be considered and actioned if whole-of-workforce frameworks were to be developed and implemented.

Essential hypertension (EH) is a disease in which both environment and genes have an important role. This study was designed to identify the interaction model between genetic variants and environmental risk factors that most highly potentiates EH development. We performed a case-control study with 1641 participants (mean age 50.6 ± 8.1 years), specifically 848 patients with EH and 793 controls, adjusted for gender and age. Traditional risk factors, biochemical and genetic parameters, including the genotypic discrimination of 14 genetic variants previously associated with EH, were investigated. Multifactorial dimensionality reduction (MDR) software was used to analyze gene-environment interactions. Validation was performed using logistic regression analysis with environmental risk factors, significant genetic variants, and the best MDR model. The best model indicates that the interactions among the ADD1 rs4961 640T allele, diabetes, and obesity (body mass index ≥30) increase approximately four-fold the risk of EH (odds ratio = 3.725; 95% confidence interval: 2.945-4.711; p < 0.0001). This work showed that the interaction between the ADD1 rs4961 variant, obesity, and the presence of diabetes increased the susceptibility to EH four-fold. In these circumstances, lifestyle adjustment and diabetes control should be intensified in patients who carry the ADD1 variant.

Identification of blood-based biomarkers of Alzheimer's disease (AD) remains a challenge. Neuropathological studies have identified enlarged endosomes in post-mortem brains as the earliest cellular change associated to AD. Here the presence of enlarged endosomes was investigated in peripheral blood mononuclear cells from 48 biologically defined AD patients (25 with mild cognitive impairment and 23 with dementia (AD-D)), and 23 age-matched healthy controls using immunocytochemistry and confocal microscopy. The volume and number of endosomes were not significantly different between AD and controls. However, the percentage of cells containing enlarged endosomes was significantly higher in the AD-D group as compared with controls. Furthermore, endosomal volumes significantly correlated to [C11]PiB cortical index measured by positron emission tomography in the AD group, independently of the APOE genotype, but not to the levels of amyloid-beta, tau and phosphorylated tau measured in the cerebrospinal fluid. Importantly, we confirmed the presence of enlarged endosomes in fibroblasts from six unrelated AD-D patients as compared with five cognitively normal controls. This study is the first, to our knowledge, to report morphological alterations of the endosomal compartment in peripheral cells from AD patients correlated to amyloid load that will now be evaluated as a possible biomarker.

The Bifocal Lenses In Nearsighted Kids (BLINK) study is the first soft multifocal contact lens myopia control study to compare add powers and measure peripheral refractive error in the vertical meridian, so it will provide important information about the potential mechanism of myopia control. The BLINK study is a National Eye Institute-sponsored, double-masked, randomized clinical trial to investigate the effects of soft multifocal contact lenses on myopia progression. This article describes the subjects' baseline characteristics and study methods. Subjects were 7 to 11 years old, had -0.75 to -5.00 spherical component and less than 1.00 diopter (D) astigmatism, and had 20/25 or better logMAR distance visual acuity with manifest refraction in each eye and with +2.50-D add soft bifocal contact lenses on both eyes. Children were randomly assigned to wear Biofinity single-vision, Biofinity Multifocal "D" with a +1.50-D add power, or Biofinity Multifocal "D" with a +2.50-D add power contact lenses. We examined 443 subjects at the baseline visits, and 294 (66.4%) subjects were enrolled. Of the enrolled subjects, 177 (60.2%) were female, and 200 (68%) were white. The mean (± SD) age was 10.3 ± 1.2 years, and 117 (39.8%) of the eligible subjects were younger than 10 years. The mean spherical equivalent refractive error, measured by cycloplegic autorefraction was -2.39 ± 1.00 D. The best-corrected binocular logMAR visual acuity with glasses was +0.01 ± 0.06 (20/21) at distance and -0.03 ± 0.08 (20/18) at near. The BLINK study subjects are similar to patients who would routinely be eligible for myopia control in practice, so the results will provide clinical information about soft bifocal contact lens myopia control as well as information about the mechanism of the treatment effect, if one occurs.

Having condoms available has been shown to be an important predictor of condom use. We examined whether or not personal norm and goal enjoyment contribute to predicting having condoms available in the context of cognition specified by the theory of planned behaviour (TPB). Prospective survey study, with a baseline and follow-up measurement (at 3 months). Data were gathered using an online survey. In total 282 adolescents (mean age = 15.6, 74% female adolescents) completed both questionnaires. At baseline, demographics, sexual experience, condom use, TPB variables, descriptive norm, personal norm, and enjoyment towards having condoms available were measured. At T2 (3 months later) having condoms available was measured. Direct and moderating effects of personal norm and goal enjoyment were examined by means of hierarchical linear regression analyses. Regression analyses yielded a direct effect of self-efficacy and personal norm on condom availability. In addition, moderation of the intention-behaviour relation by goal enjoyment added to the variance explained. The final model explained approximately 35% of the variance in condom availability. Personal norm and goal enjoyment add to the predictive utility of a TPB model of having condoms available and may be useful intervention targets. What is already known about this subject? Having condoms available is an important prerequisite for actual condom use. The theory of planned behaviour has successfully been applied to explain condom availability behaviour. The theory of planned behaviour has been criticized for not adequately taking into account affective motivation. What does this study add? Personal norm and goal enjoyment add to the predictive utility of the model. Personal norm explains condom availability directly, enjoyment increases intention enactment. Personal norm and goal enjoyment therefore are useful intervention targets. © 2012 The British Psychological Society.

Add-on ketamine anesthesia in electroconvulsive therapy (ECT) has been studied in depressive patients in several clinical trials with inconclusive findings. Two most recent meta-analyses reported insignificant findings with regards to the treatment effect of add-on ketamine anesthesia in ECT in depressive patients. The aim of this study is to update the current evidence and investigate the role of add-on ketamine anesthesia in ECT in depressive patients via a systematic review and meta-analysis. We performed a thorough literature search of the PubMed and ScienceDirect databases, and extracted all relevant clinical variables to compare the antidepressive outcomes between add-on ketamine anesthesia and other anesthetics in ECT. Total 16 articles with 346 patients receiving add-on ketamine anesthesia in ECT and 329 controls were recruited. We found that the antidepressive treatment effect of add-on ketamine anesthesia in ECT in depressive patients was significantly higher than that of other anesthetics (p<0.001). This significance persisted in both short-term (1-2 weeks) and moderate-term (3-4 weeks) treatment courses (all p<0.05). However, the side effect profiles and recovery time profiles were significantly worse in add-on ketamine anesthesia group than in control group. Our meta-analysis highlights the significantly higher antidepressive treatment effect of add-on ketamine in depressive patients receiving ECT compared to other anesthetics. However, clinicians need to take undesirable side effects into consideration when using add-on ketamine anesthesia in ECT in depressive patients. Copyright © 2016 Elsevier B.V. and ECNP.

2013-01-01

Meta-analysis of case studies has become an important tool for synthesizing case study findings in land change. Meta-analyses of deforestation, urbanization, desertification and change in shifting cultivation systems have been published. This present study adds to this literature, with an analysis of the proximate causes and underlying forces of wetland conversion at a global scale using two complementary approaches of systematic review. Firstly, a meta-analysis of 105 case-study papers describing wetland conversion was performed, showing that different combinations of multiple-factor proximate causes, and underlying forces, drive wetland conversion. Agricultural development has been the main proximate cause of wetland conversion, and economic growth and population density are the most frequently identified underlying forces. Secondly, to add a more quantitative component to the study, a logistic meta-regression analysis was performed to estimate the likelihood of wetland conversion worldwide, using globally-consistent biophysical and socioeconomic location factor maps. Significant factors explaining wetland conversion, in order of importance, are market influence, total wetland area (lower conversion probability), mean annual temperature and cropland or built-up area. The regression analyses results support the outcomes of the meta-analysis of the processes of conversion mentioned in the individual case studies. In other meta-analyses of land change, similar factors (e.g., agricultural development, population growth, market/economic factors) are also identified as important causes of various types of land change (e.g., deforestation, desertification). Meta-analysis helps to identify commonalities across the various local case studies and identify which variables may lead to individual cases to behave differently. The meta-regression provides maps indicating the likelihood of wetland conversion worldwide based on the location factors that have determined historic conversions.

OBJECTIVE: To analyze the anteroposterior displacement of the knee by means of stress radiography in individuals with unilateral anterior knee instability and relate to time of instability. METHODS: Sixty individuals with intact knees (control group) and 125 patients with unilateral anterior instability (AI group) agreed to participate in the study. Gender, age, weight, height, age at injury, time between injury and testing, and surgical findings are studied. Both groups are submitted to anterior and posterior stress radiographies of both knees. Anterior (ADD) and posterior displacement difference (PDD) were calculated between sides. RESULTS: In the control group ADD and PDD are in average, zero, whereas in the AI group ADD averaged 9.8mm and PDD, 1.92mm. Gender, age, weight, height, age at trauma and presence of menisci's lesions do not intervene in the values of ADD and PDD. Meniscal injuries increase with time. ADD and PDD do not relate with the presence or absence of associated menisci's lesions. The ADD and the PDD are related to each other and increase with time. CONCLUSION: There is a permanent anterior subluxation of the injured knee that is related to the amount of anterior displacement that increases with time.

The aim of this work is to present a comparison of the main semi active suspension systems used in a passenger car, after having optimized the suspension systems of the vehicle model in respect with ride comfort and road holding. Thus, a half car model, equipped with controllable dampers, along with a seat and a driver was implemented. Semi-active suspensions have received a lot of attention since they seem to provide the best compromise between cost (energy consumption, actuators/sensors hardware) and performance in comparison with active and passive suspensions. In this work, the semi active suspension systems studied are comfort oriented and consist of (a) the two version of Skyhook control (two states skyhook and skyhook linear approximation damper), (b) the acceleration driven damper (ADD), (c) the power driven damper (PDD), (d) the combination of Skyhook and ADD (Mixed Skyhook-ADD) and (e) the combination of the two with the use of a sensor. The half car model equipped with the above suspension systems was excited by a road bump, and was optimized using genetic algorithms (GA) in respect with ride comfort and road holding. This study aims to highlight how the optimization of the vehicle model could lead to the best compromise between ride comfort and road holding, overcoming their well-known trade-off. The optimum results were compared with important performance metrics regarding the vehicle’s dynamic behaviour in general.

Global analysis of double-strand break processing reveals in vivo properties of the helicase-nuclease complex AddAB

PubMed Central

Badrinarayanan, Anjana; Cisse, Ibrahim I.

2017-01-01

In bacteria, double-strand break (DSB) repair via homologous recombination is thought to be initiated through the bi-directional degradation and resection of DNA ends by a helicase-nuclease complex such as AddAB. The activity of AddAB has been well-studied in vitro, with translocation speeds between 400–2000 bp/s on linear DNA suggesting that a large section of DNA around a break site is processed for repair. However, the translocation rate and activity of AddAB in vivo is not known, and how AddAB is regulated to prevent excessive DNA degradation around a break site is unclear. To examine the functions and mechanistic regulation of AddAB inside bacterial cells, we developed a next-generation sequencing-based approach to assay DNA processing after a site-specific DSB was introduced on the chromosome of Caulobacter crescentus. Using this assay we determined the in vivo rates of DSB processing by AddAB and found that putative chi sites attenuate processing in a RecA-dependent manner. This RecA-mediated regulation of AddAB prevents the excessive loss of DNA around a break site, limiting the effects of DSB processing on transcription. In sum, our results, taken together with prior studies, support a mechanism for regulating AddAB that couples two key events of DSB repair–the attenuation of DNA-end processing and the initiation of homology search by RecA–thereby helping to ensure that genomic integrity is maintained during DSB repair.

The added value of inclusive research.

2017-12-12

The study asks when does inclusive research add value? The authors argue that this is important, given the additional time and cost of co-researching with people with intellectual disabilities. The study is situated in debates about a "second generation" of inclusive research which advocates focussing more on outcomes than process. The authors argue that this is premature, rather the authors propose that inclusive research is valuable when it helps to recognize, foster, and above all communicate the contributions people with intellectual disabilities can make. The authors conducted a literature review of 52 peer-reviewed journal articles about inclusive research and analysed them.. The authors conclude that inclusive research adds value when there is a distinctive contribution which only co-researchers with intellectual disabilities can make, when it highlights the contributions people with intellectual disabilities make, and when it contributes to better lives for the wider population of people with intellectual disabilities. The authors propose a revised definition of inclusive research to replace that published by Walmsley and Johnson in 2003. © 2017 John Wiley & Sons Ltd.

When handling Y-labelled and Lu-labelled radiopharmaceuticals, skin exposure is mainly due to β-particles. This study aimed to investigate the equivalent dose saving of the staff when changing from an essentially manual radiolabelling procedure to an automatic dose dispenser (ADD). The chemist and physician were asked to wear thermoluminescence dosimeters on their fingertips to evaluate the quantity of Hp(0.07) on the skin. Data collected were divided into two groups: before introducing ADD (no ADD) and after introducing ADD. For the chemist, the mean values (95th percentile) of Hp(0.07) for no ADD and ADD are 0.030 (0.099) and 0.019 (0.076) mSv/GBq, respectively, for Y, and 0.022 (0.037) and 0.007 (0.023) mSv/GBq, respectively, for Lu. The reduction for ADD was significant (t-test with P<0.05) for both isotopes. The relative differences before and after ADD collected for every finger were treated using the Wilcoxon test, proving a significantly higher reduction in extremity dose to each fingertip for Lu than for Y (P<0.05). For the medical staff, the mean values of Hp(0.07) (95th percentile) for no ADD and ADD are 0.021 (0.0762) and 0.0143 (0.0565) mSv/GBq, respectively, for Y, and 0.0011 (0.00196) and 0.0009 (0.00263) mSv/GBq, respectively, for Lu. The t-test provided a P-value less than 0.05 for both isotopes, making the difference between ADD and no ADD significant. ADD positively affects the dose saving of the chemist in handling both isotopes. For the medical staff not directly involved with the introduction of the ADD system, the analysis shows a learning curve of the workers over a 5-year period. Specific devices and procedures allow staff skin dose to be limited.

Can infants' object concepts be trained?

Decades of research and debate on the origins of object permanence in infancy have contrasted various types of learning with possible innate contributions. A recent paper by Johnson et al. adds a new perspective to this debate by reporting that even very brief training periods can dramatically influence infants' persisting object representations. Such training studies have the potential to constrain 'nature versus nurture' debates in novel ways, although important challenges remain.

While nonhuman animal remains are often utilized in forensic research to develop methods to estimate the postmortem interval, systematic studies that directly validate animals as proxies for human decomposition are lacking. The current project compared decomposition rates among pigs, rabbits, and humans at the University of Tennessee's Anthropology Research Facility across three seasonal trials that spanned nearly 2 years. The Total Body Score (TBS) method was applied to quantify decomposition changes and calculate the postmortem interval (PMI) in accumulated degree days (ADD). Decomposition trajectories were analyzed by comparing the estimated and actual ADD for each seasonal trial and by fuzzy cluster analysis. The cluster analysis demonstrated that the rabbits formed one group while pigs and humans, although more similar to each other than either to rabbits, still showed important differences in decomposition patterns. The decomposition trends show that neither nonhuman model captured the pattern, rate, and variability of human decomposition. © 2018 American Academy of Forensic Sciences.

The decomposition process of human remains can be used to estimate the post-mortem interval (PMI), but decomposition varies due to many factors. Temperature is believed to be the most important and can be connected to decomposition by using the accumulated degree days (ADD). The aim of this research was to develop a decomposition scoring method and to develop a formula to estimate the PMI by using the developed decomposition scoring method and ADD.A decomposition scoring method and a Book of Reference (visual resource) were made. Ninety-one cases were used to develop a method to estimate the PMI. The photographs were scored using the decomposition scoring method. The temperature data was provided by the Royal Netherlands Meteorological Institute. The PMI was estimated using the total decomposition score (TDS) and using the TDS and ADD. The latter required an additional step, namely to calculate the ADD from the finding date back until the predicted day of death.The developed decomposition scoring method had a high interrater reliability. The TDS significantly estimates the PMI (R 2  = 0.67 and 0.80 for indoor and outdoor bodies, respectively). When using the ADD, the R 2 decreased to 0.66 and 0.56.The developed decomposition scoring method is a practical method to measure decomposition for human remains found on land. The PMI can be estimated using this method, but caution is advised in cases with a long PMI. The ADD does not account for all the heat present in a decomposing remain and is therefore a possible bias.

Feasibility study of veterinary antibiotic consumption in Germany--comparison of ADDs and UDDs by animal production type, antimicrobial class and indication.

Within a feasibility study the use of antibiotics in pigs and cattle was determined in 24 veterinary practices in Lower Saxony and on 66 farms in North Rhine-Westphalia in Germany. Focus was laid on the comparison of the Used Daily Doses (UDD) (dose per animal and day prescribed by the veterinarians) with the Defined Animal Daily Doses (ADD) (dose per animal and day calculated by means of recommended dosages and estimated live weights). For piglets and calves most of the UDD (50% and 46% of nUDD, respectively) were above the ADD (i.e. UDD/ADD-ratio above 1.25). Regarding sows, fattening pigs, dairy and beef cattle, most of the UDDs (49% to 65% of nUDD) were lower than the respective ADD (i.e. UDD/ADD-ratio below 0.8). In pigs, the UDDs of beta-lactams, fluoroquinolones and cephalosporins, and in cattle, those of macrolides and beta-lactams were often below the ADDs. Tetracyclines were frequently used above the recommended dose.Enteric diseases were more often treated below the recommended dose than respiratory diseases, possibly due to overestimation of the live weight (diarrhea in young animals, respiratory diseases in elder animals) and consequently overestimation of the recommended dose. Comparisons between UDD and ADD can be used to observe differences between antimicrobials and trends in the usage of antibiotics. But individual treatment comparisons of UDD and ADD must be interpreted carefully, because they may be due to lower live weights than estimated. Correlating such data with data on the occurrence of resistant bacteria in future may help to improve resistance prevention and control.

Background Within a feasibility study the use of antibiotics in pigs and cattle was determined in 24 veterinary practices in Lower Saxony and on 66 farms in North Rhine-Westphalia in Germany. Focus was laid on the comparison of the Used Daily Doses (UDD) (dose per animal and day prescribed by the veterinarians) with the Defined Animal Daily Doses (ADD) (dose per animal and day calculated by means of recommended dosages and estimated live weights). Results For piglets and calves most of the UDD (50% and 46% of nUDD, respectively) were above the ADD (i.e. UDD/ADD-ratio above 1.25). Regarding sows, fattening pigs, dairy and beef cattle, most of the UDDs (49% to 65% of nUDD) were lower than the respective ADD (i.e. UDD/ADD-ratio below 0.8). In pigs, the UDDs of beta-lactams, fluoroquinolones and cephalosporins, and in cattle, those of macrolides and beta-lactams were often below the ADDs. Tetracyclines were frequently used above the recommended dose. Enteric diseases were more often treated below the recommended dose than respiratory diseases, possibly due to overestimation of the live weight (diarrhea in young animals, respiratory diseases in elder animals) and consequently overestimation of the recommended dose. Conclusion Comparisons between UDD and ADD can be used to observe differences between antimicrobials and trends in the usage of antibiotics. But individual treatment comparisons of UDD and ADD must be interpreted carefully, because they may be due to lower live weights than estimated. Correlating such data with data on the occurrence of resistant bacteria in future may help to improve resistance prevention and control. PMID:24401194

2014-02-24

Tactile stimulation is key for the posterior brain re-organization activity and attention processes, however the impact of tactile stimulation on attention deficit disorder (ADD) in blind children remains unexplored. We carried out a study with children having or not ADD (four per group). The subjects have been exposed during six months to tactile stimulation protocol consisting in two daily sessions (morning and afternoon sessions) of 30 minutes each. We have measured the ability to detect an infrequent tactile stimulus, reaction time, latency of P300, sources of brain activity, and ADD clinical symptoms, before and after tactile training. Passive tactile stimulation significantly improves ADD clinical symptoms, particularly attention, behavior and self-control of involuntary movements and tics. In addition, tactile stimulation changes the pattern of brain activity in ADD blind children inducing activity in frontal and occipital areas, which could be associated to a compensation of the attention deficit. Passive tactile stimulation training may improve ADD clinical symptoms and can reorganize the pattern of brain activity in blind ADD children.

Anxiety and/or Depressive Disorders (ADDs) and Chronic Somatic Diseases (CSDs) are associated with substantial levels of health-related disability and work impairment. However, it is unclear whether comorbid ADDs and CSDs additively affect functional outcomes. This paper examines the impact of ADDs, CSDs, and their comorbidity on disability, work absenteeism and presenteeism. Baseline data from the Netherlands Study of Depression and Anxiety (n=2371) were used. We assessed presence of current ADDs (using psychiatric interviews, CIDI) and presence of self-reported CSDs. Outcome measures were disability scores (WHO-DAS II questionnaire, overall and domain-specific), work absenteeism (≤2weeks and >2weeks; TiC-P) and presenteeism (reduced and impaired work performance; TiC-P). We conducted multivariate regression analyses adjusted for socio-demographics. Both ADDs and CSDs significantly and independently impact total disability, but the impact was substantially larger for ADDs (main effect unstandardized β=20.1, p<.001) than for CSDs (main effect unstandardized β=3.88, p<.001). There was a positive interaction between ADDs and CSDs on disability (unstandardized β interaction=4.06, p=.004). Although CSDs also induce absenteeism (OR for extended absenteeism=1.42, p=.015) and presenteeism (OR for impaired work performance=1.42, p=.013), associations with ADDs were stronger (OR for extended absenteeism=6.64, p<.001; OR for impaired work performance=7.51, p<.001). Both CSDs and ADDs cause substantial disability, work absenteeism and presenteeism, but the impact of ADDs far exceeds that of CSDs. CSDs and ADDs interact synergistically on disability, thereby bolstering the current view that patients with physical mental comorbidity (PM-comorbidity) form a severe subgroup with an unfavourable prognosis.

Aim To investigate the feasibility and utility of the Analytic Hierarchy Process (AHP) for medication decision-making in type 2 diabetes. Methods We conducted an AHP with nine diabetes experts using structured interviews to rank add-on therapies (to metformin) for type 2 diabetes. During the AHP, participants compared treatment alternatives relative to eight outcomes (hemoglobin A1c-lowering and seven potential harms) and the relative importance of the different outcomes. The AHP model and instrument were pre-tested and pilot-tested prior to use. Results were discussed and an evaluation of the AHP was conducted during a group session. We conducted the quantitative analysis using Expert Choice software with the ideal mode to determine the priority of treatment alternatives. Results Participants judged exenatide to be the best add-on therapy followed by sitagliptin, sulfonylureas, and then pioglitazone. Maximizing benefit was judged 21% more important than minimizing harm. Minimizing severe hypoglycemia was judged to be the most important harm to avoid. Exenatide was the best overall alternative if the importance of minimizing harms was prioritized completely over maximizing benefits. Participants reported that the AHP improved transparency, consistency, and an understanding of others’ perspectives and agreed that the results reflected the views of the group. Conclusions The AHP is feasible and useful to make decisions about diabetes medications. Future studies which incorporate stakeholder preferences should evaluate other decision contexts, objectives, and treatments. PMID:26000636

Role of central obesity in risk stratification after an acute coronary event: does central obesity add prognostic value to the Global Registry of Acute Coronary Events (GRACE) risk score in patients with acute coronary syndrome?

Accurate risk stratification is an important step in the initial management of acute coronary syndrome (ACS), and current guidelines recommend the use of risk scores, such as the Global Registry of Acute Coronary Events risk score (GRACE RS). Recent studies have suggested that abdominal obesity is associated with cardiovascular events in patients with ACS. However, little is known about the additional value of abdominal obesity beyond risk scores. The aim of our study was thus to assess whether waist circumference, a surrogate of abdominal adiposity, adds prognostic information to the GRACE RS. This was a retrospective cohort study of ACS patients admitted consecutively to a cardiac care unit between June 2009 and July 2010. The composite of all-cause mortality or myocardial reinfarction within six months of index hospitalization was used as the endpoint for the analysis. A total of 285 patients were studied, 96.1% admitted for myocardial infarction (with or without ST elevation) and 3.9% for unstable angina. At the end of the follow-up period, 10 patients had died and the composite endpoint had been reached in 27 patients (9.5%). More than 70% of the study population were obese or overweight, and abdominal obesity was present in 44.6%. The GRACE RS showed poor predictive accuracy (area under the curve 0.60), and most of the GRACE variables did not reach statistical significance in multivariate analysis. The addition of waist circumference to the GRACE RS did not improve its discriminatory performance. Abdominal obesity does not add prognostic information to the GRACE RS to predict six-month mortality or myocardial reinfarction.

The objective of this study was to use a qualitative approach to examine the perceptions of dentists who led a health promotion programme entitled "Baby Teeth DO Matter". Semi-structured interviews were undertaken with a variety of participants in a health promotional programme facilitated by a shadow Local Professional Network. These were then recorded and transcribed verbatim. The transcripts were line numbered and subjected to thematic analysis to develop a coding frame. Overarching themes were developed from the coded transcripts by organising them into clusters based on the similarity of their meaning and checked against the coded extracts and the raw data. General Dental Practice. General Dental Practitioners. A Greater Manchester-wide prevention programme entitled "Baby teeth DO Matter". To determine the perceptions of involved clinicians and whether "clinically owned and clinically led" services add value. Eight codes were generated: "Success of the project", "Down-stream to up-stream", "Importance of clinically led and clinically owned", "Keeping the approach simple", "Importance of networking", "Importance of Dental Public Health", "Importance of task and finish" and "Threats to the future of the Local Professional Network". These were organised into three over-arching themes. "Clinically Led and Clinically Owned" projects appear to empower local practitioners and add value. They encourage community-facing practitioners, build capacity and develop personal skills;--all in accordance with the fundamental principles of the Ottawa Charter. Distributed leadership was seen to be effective and Dental Public Health input, "Task and Finishing", resources and clarity of communication were all considered to be of critical importance.

The National Aeronautics and Space Administration's (NASA's) major wind tunnel (WT), propulsion test (PT), and simulation facilities exist to serve NASA's and the nation's aeronautics needs. RAND Corporation researchers conducted a prior study of these facilities from 2002 to 2003, identifying (1) NASA's continuing ability to serve national needs, (2) which facilities appear strategically important from an engineering perspective given the vehicle classes the nation investigates and produces, and (3) management challenges and issues. This documented briefing (DB) is the final report from a new, one-year study (conducted from September 2006 through January 2008), partially updating the prior assessment. The study focuses on updating the list of facilities in the prior study that were deemed to be strategically important (again, from an engineering perspective) in serving those needs. This update also adds a new assessment of national needs for six major aeronautics simulators at NASA and lists those deemed strategically important.

Purpose Retrospective studies of preconception health have demonstrated that parents’ health conditions and behaviors can impact a newborn’s birth outcomes and, subsequently, future health status. This study sought to examine the impact of preconception health, measured prospectively, among both mothers and fathers, on two important birth outcomes: birthweight and gestational age. Methods Data came from Add Health (the National Longitudinal Study of Adolescent Health), which included interviews with original participants and a subsample of their partners in 2001–02. In 2008, the original respondents again completed an interview for Add Health. For 372 eligible infants born to these couples, birth outcomes (measured in 2008) were regressed on preconception health conditions and behaviors among non-pregnant heterosexual partners (measured in 2001–02). Results Mean birthweight was 3399 grams, and mean gestational age was 39 weeks. Birthweight was higher for infants born to mothers with diabetes or high blood pressure, and for mothers who drank alcohol at least once per month, and lower for infants born to fathers with diabetes (p < .05). Infant gestational age was marginally lower for infants born to mothers with higher levels of depression (p < .10), and lower for infants born to fathers with diabetes and with higher levels of fast food consumption (p < .05). Conclusions Both maternal and paternal preconception health conditions and behaviors influenced infant birth outcomes. Interventions to promote preconception health should focus on prevention of diabetes and high blood pressure, as well as minimizing consumption of alcohol and fast food. PMID:25367598

Tinnitus is described as a disturbing sound sensation in the absence of external stimulation. We aimed to investigate whether there is any relationship between severe chronic tinnitus and angiotensin-converting enzyme (ACE) I/D and α-adducin (ADD1) G460W gene polymorphisms. The patient group and control group consisted of 89 and 104 individuals, respectively. The evaluation of tinnitus was performed using the Strukturiertes Tinnitus-Interview (STI). The Tinnitus Handicap Inventory (THI) was used to evaluate the tinnitus severity. Polymerase chain reaction (PCR) and polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) techniques were used for genotyping. With regard to the ACE I/D polymorphism, there was no significant difference in genotype and allele frequencies between the patient group and control group. However, a statistically significant difference was found in genotype (p<0.01) and allele frequencies (p=0.021) of the ADD1 G460W gene polymorphism. Combined genotype analysis showed that the ACE II /ADD1 GW genotype was statistically significantly higher in the patient group than in the control group (X2: 7.15, p=0.007). The odds ratio value of the GW genotype was 2.5 (95% CI=1.4-4.7) (p<0.01). Our results demonstrate an association between ADD1 G460W gene polymorphism and susceptibility to severe chronic tinnitus. It was found that the GW genotype increased the disease risk by 2.5-fold compared with other genotypes. This indicates that ADD1 G460W polymorphism could be an important factor in the pathophysiology of tinnitus.

Deep Transcranial Magnetic Stimulation (dTMS) can be an alternative treatment to relieve pain in chronic migraine (CM). The aim of this study was to evaluate the effect of high-frequency dTMS in add-on to standard treatment for CM in patients not responding to effective abortive or preventive drug treatment. We randomized 14 patients with International Classification of Headache Disorders, 3rd Edition (ICHD-3) treatment-resistant CM to add-on dTMS (n=7) or standard abortive or preventive antimigraine treatment (n=7). Three sessions of alternate day 10Hz dTMS consisting of 600 pulses in 10 trains were delivered to the dorsolateral prefrontal cortex (DLPFC), bilaterally, but with left hemisphere prevalence, for 12 sessions spread over one month. The add-on dTMS treatment was well tolerated. Patients treated with dTMS showed significant reduction of pain intensity, frequency of attacks, analgesic overuse, and depressive symptoms during treatment and one month later, compared to the month preceding treatment and at the same time-points compared to the control group. As compared to standard pharmacological treatment alone, add-on high-frequency dTMS of the bilateral DLPFC reduced the frequency and intensity of migraine attack, drug overuse, and depressive symptoms. This study supports the add-on dTMS treatment in treatment-resistant CM. Copyright © 2016. Published by Elsevier Ireland Ltd.

Add-on conservation benefits of marine territorial user rights fishery policies in central Chile.

Gelcich, Stefan; Godoy, Natalio; Prado, Luis; Castilla, Juan Carlos

2008-01-01

To combine the rational use of marine benthic resources and economic development of small-scale fishers, Chile passed legislation in 1991 establishing a comanagement policy that grants exclusive territorial user rights for fisheries (TURFs) to artisanal fisher organizations in well-defined inshore coastal areas, known as Management and Exploitation Areas for Benthic Resources (MEABRs). In general the policy has been proclaimed a management and economic success because benthic resource abundances have increased inside MEABRs in comparison with open-access areas. However, there is a lack of studies assessing the impact of this management policy on nontargeted subtidal species and community assemblages and the policy's implications for biodiversity and conservation. This study starts to fill this gap and links the allocation of TURFs for benthic resources with add-on conservation benefits for species that are not directly linked with the fishery policy. Comparative subtidal surveys inside vs. outside MEABRs were used to assess the effects of three MEABRs on managed targeted benthic species, biodiversity (species richness), and community assemblages in central Chile. Surveys focused exclusively on subtidal kelp forest habitats dominated by Lessonia trabeculata, spanning 4-12 m in depth and with similar levels of habitat complexity. The study comprised: (1) quantification of kelp forest complexity, (2) understory survey of sessile species, (3) quantification of conspicuous benthic macroinvertebrates, including those under management, and (4) quantification of reef-fish species inside the kelp habitat. Results showed population enhancement of target-managed invertebrates inside MEABRs. Moreover, reef-fish species were significantly more diverse and abundant inside MEABRs, and community assemblages of nontarget benthic invertebrates and reef fish were significantly different inside vs. outside MEABRs. The comanagement of inshore benthic resources in Chile, through MEABRs aims for the sustainability of invertebrate and algae stocks. However, our study shows that this management tool, which in practice restricts access to the entire management area, provides important conservation add-on effects for species that are not the focus of the management policies. Therefore, in Chile, the hundreds of already established MEABRs could represent an important ancillary network, which complements the biodiversity objectives of fully protected areas such as no-take marine protected areas or others.

The aim of this study was to assess the role of add-on devices for the prevention of phlebitis and other complications associated with the use of peripheral catheters. Patients admitted to an infectious diseases ward and requiring the insertion of a peripheral catheter for at least 24h were randomly allocated to be managed with or without add-on devices. Incidence of phlebitis and all complications were the primary outcomes. Extravasation, inadvertent withdrawal, obstruction and rupture were considered to be mechanical complications, and analysis was performed using survival methods. Of 683 evaluated catheters, 351 were allocated to the add-on device arm and 332 to the control arm. Despite randomisation, patients in the add-on device group were older (P=0.048), less likely to have human immunodeficiency virus (P=0.02) and more likely to have received antibiotics (P=0.05). After adjustment for these variables, the hazard ratio for phlebitis remained non-significant (hazard ratio: 0.95; 95% confidence interval: 0.7-1.3), but the risk of mechanical complications became lower in the add-on device arm (0.68; 0.5-0.94). This translated into a trend towards a lower risk of any complication (0.83; 0.67-1.01). The beneficial effect on mechanical or all complications was noticeable after six days of catheterisation. Add-on devices do not reduce the incidence of phlebitis but may prevent mechanical complications. However, the impact of add-on devices on the incidence of all complications is at most small and only apparent after the sixth day of catheter use.

Tolvaptan (TLV) is known to increase electrolyte-free water clearance. However, TLV actions on renal electrolytes including urine sodium (uNa) excretion and its consequences are less well understood. This subanalysis investigated the effect of add-on TLV compared to increased furosemide (FUR) on both electrolyte-free water and electrolyte clearance in patients with congestive heart failure (CHF) complicated by advanced chronic kidney disease (CKD). The Kanagawa Aquaresis Investigators Trial of TLV on HF Patients with Renal Impairment (K-STAR) was a multicenter, open-labeled, randomized, and controlled prospective clinical study. Eighty-one Japanese patients with CHF and residual signs of congestion despite oral FUR treatment (≥ 40 mg/day) were recruited and randomly assigned to a 7-day add-on treatment with either ≤ 40 mg/day FUR or ≤ 15 mg/day TLV. Electrolyte-free water clearance, electrolyte osmolar clearance and electrolyte excretion were compared between the two groups before and after therapy. The change (Δ) in electrolyte-free water clearance was significantly higher in the add-on TLV group than in the add-on FUR group. However, Δelectrolyte osmolar clearance was also higher in the add-on TLV group than in the increased FUR group. This was primarily because ΔuNa excretion was significantly higher in the add-on TLV group than in the increased FUR group, since Δurine potassium excretion was significantly lower in the add-on TLV group than in the increased FUR group. Add-on TLV may increase both renal water and Na excretion in CHF patients with advanced CKD to a greater degree than increased FUR.

Enzymic aromatization of 6-alkyl-substituted androgens, potent competitive and mechanism-based inhibitors of aromatase.

1998-01-01

To gain insight into the relationships between the aromatase inhibitory activity of 6-alkyl-substituted androgens, potent competitive inhibitors, and their ability to serve as a substrate of aromatase, we studied the aromatization of a series of 6alpha- and 6beta-alkyl (methyl, ethyl, n-propyl, n-pentyl and n-heptyl)-substituted androst-4-ene-3,17-diones (ADs) and their androsta-1,4-diene-3,17-dione (ADD) derivatives with human placental aromatase, by gas chromatography-mass spectrometry. Among the inhibitors examined, ADD and its 6alpha-alkyl derivatives with alkyl functions less than three carbons long, together with 6beta-methyl ADD, are suicide substrates of aromatase. All of the steroids, except for 6beta-n-pentyl ADD and its n-heptyl analogue as well as 6beta-n-heptyl AD, were found to be converted into the corresponding 6-alkyl oestrogens. The 6-methyl steroids were aromatized most efficiently in each series, and the aromatization rate essentially decreased in proportion to the length of the 6-alkyl chains in each series, where the 6alpha-alkyl androgens were more efficient substrates than the corresponding 6beta isomers. The Vmax of 6alpha-methyl ADD was approx. 2.5-fold that of the natural substrate AD and approx. 3-fold that of the parent ADD. On the basis of this, along with the facts that the rates of a mechanism-based inactivation of aromatase by ADD and its 6alpha-methyl derivative are similar, it is implied that alignment of 6alpha-methyl ADD in the active site could favour the pathway leading to oestrogen over the inactivation pathway, compared with that of ADD. The relative apparent Km values for the androgens obtained in this study are different from the relative Ki values obtained previously, indicating that there is a difference between the ability to serve as an inhibitor and the ability to serve as a substrate in the 6-alkyl androgen series.

18 F-florbetapir uptake by brain tissue measured by positron emission tomography (PET) is accepted by regulatory agencies like the Food and Drug Administration (FDA) and the European Medicine Agencies (EMA) for assessing amyloid load in people with dementia. Its added value is mainly demonstrated by excluding Alzheimer's pathology in an established dementia diagnosis. However, the National Institute on Aging and Alzheimer's Association (NIA-AA) revised the diagnostic criteria for Alzheimer's disease and confidence in the diagnosis of mild cognitive impairment (MCI) due to Alzheimer's disease may be increased when using amyloid biomarkers tests like 18 F-florbetapir. These tests, added to the MCI core clinical criteria, might increase the diagnostic test accuracy (DTA) of a testing strategy. However, the DTA of 18 F-florbetapir to predict the progression from MCI to Alzheimer's disease dementia (ADD) or other dementias has not yet been systematically evaluated. To determine the DTA of the 18 F-florbetapir PET scan for detecting people with MCI at time of performing the test who will clinically progress to ADD, other forms of dementia (non-ADD), or any form of dementia at follow-up. This review is current to May 2017. We searched MEDLINE (OvidSP), Embase (OvidSP), PsycINFO (OvidSP), BIOSIS Citation Index (Thomson Reuters Web of Science), Web of Science Core Collection, including the Science Citation Index (Thomson Reuters Web of Science) and the Conference Proceedings Citation Index (Thomson Reuters Web of Science), LILACS (BIREME), CINAHL (EBSCOhost), ClinicalTrials.gov (https://clinicaltrials.gov), and the World Health Organization International Clinical Trials Registry Platform (WHO ICTRP) (http://www.who.int/ictrp/search/en/). We also searched ALOIS, the Cochrane Dementia & Cognitive Improvement Group's specialised register of dementia studies (http://www.medicine.ox.ac.uk/alois/). We checked the reference lists of any relevant studies and systematic reviews, and performed citation tracking using the Science Citation Index to identify any additional relevant studies. No language or date restrictions were applied to the electronic searches. We included studies that had prospectively defined cohorts with any accepted definition of MCI at time of performing the test and the use of 18 F-florbetapir scan to evaluate the DTA of the progression from MCI to ADD or other forms of dementia. In addition, we only selected studies that applied a reference standard for Alzheimer's dementia diagnosis, for example, National Institute of Neurological and Communicative Disorders and Stroke and the Alzheimer's Disease and Related Disorders Association (NINCDS-ADRDA) or Diagnostic and Statistical Manual of Mental Disorders-IV (DSM-IV) criteria. We screened all titles and abstracts identified in electronic-database searches. Two review authors independently selected studies for inclusion and extracted data to create two-by-two tables, showing the binary test results cross-classified with the binary reference standard. We used these data to calculate sensitivities, specificities, and their 95% confidence intervals. Two independent assessors performed quality assessment using the QUADAS-2 tool plus some additional items to assess the methodological quality of the included studies. We included three studies, two of which evaluated the progression from MCI to ADD, and one evaluated the progression from MCI to any form of dementia.Progression from MCI to ADD was evaluated in 448 participants. The studies reported data on 401 participants with 1.6 years of follow-up and in 47 participants with three years of follow-up. Sixty-one (15.2%) participants converted at 1.6 years follow-up; nine (19.1%) participants converted at three years of follow-up.Progression from MCI to any form of dementia was evaluated in five participants with 1.5 years of follow-up, with three (60%) participants converting to any form of dementia.There were concerns regarding applicability in the reference standard in all three studies. Regarding the domain of flow and timing, two studies were considered at high risk of bias. MCI to ADD;Progression from MCI to ADD in those with a follow-up between two to less than four years had a sensitivity of 67% (95% CI 30 to 93) and a specificity of 71% (95% CI 54 to 85) by visual assessment (n = 47, 1 study).Progression from MCI to ADD in those with a follow-up between one to less than two years had a sensitivity of 89% (95% CI 78 to 95) and a specificity of 58% (95% CI 53 to 64) by visual assessment, and a sensitivity of 87% (95% CI 76 to 94) and a specificity of 51% (95% CI 45 to 56) by quantitative assessment by the standardised uptake value ratio (SUVR)(n = 401, 1 study). MCI to any form of dementia;Progression from MCI to any form of dementia in those with a follow-up between one to less than two years had a sensitivity of 67% (95% CI 9 to 99) and a specificity of 50% (95% CI 1 to 99) by visual assessment (n = 5, 1 study). MCI to any other forms of dementia (non-ADD);There was no information regarding the progression from MCI to any other form of dementia (non-ADD). Although sensitivity was good in one included study, considering the poor specificity and the limited data available in the literature, we cannot recommend routine use of 18 F-florbetapir PET in clinical practice to predict the progression from MCI to ADD.Because of the poor sensitivity and specificity, limited number of included participants, and the limited data available in the literature, we cannot recommend its routine use in clinical practice to predict the progression from MCI to any form of dementia.Because of the high financial costs of 18 F-florbetapir, clearly demonstrating the DTA and standardising the process of this modality are important prior to its wider use.

Exposure of the tube of an aqueous drainage device (ADD) through the conjunctiva is a serious complication of ADD surgery. Although placement of gamma-irradiated sterile cornea (GISC) as a patch graft over the tube is commonly performed, exposures still occur. To measure GISC patch graft thickness as a function of time after surgery, estimate the rate of graft thinning, and determine risk factors for graft thinning. Cross-sectional study of graft thickness using anterior segment optic coherence tomography (AS-OCT) was conducted at the Wilmer Eye Institute at Johns Hopkins Hospital. A total of 107 patients (120 eyes, 120 ADDs) 18 years or older who underwent ADD surgery at Johns Hopkins with GISC patch graft between July 1, 2010, and October 31, 2016, were enrolled. Implantation of ADD with placement of GISC patch graft over the tube. Graft thickness vs time after ADD surgery and risk factors for undetectable graft. Of the 107 patients included in the analysis, the mean (SD) age of the cohort was 64 (16.2) years, 49 (45.8%) were male, and 43 (40.2%) were African American. The mean time of measurement after surgery was 1.7 years (range, 1 day to 6 years). Thinner grafts were observed as the time after surgery lengthened (β regression coefficient, -60 µm per year since surgery; 95% CI, -80 µm to -40 µm). The odds ratio of undetectable grafts per year after ADD surgery was 2.1 (95% CI, 1.5-3.0; P < .001). Age, sex, race, type of ADD, quadrant of ADD placement, diagnosis of uveitis or dry eye, and prior conjunctival surgery were not correlated with the presence or absence of the graft. Gamma-irradiated sterile corneal patch grafts do not always retain their integrity after ADD surgery. Data from this cross-sectional study showed that on average, the longer the time after surgery, the thinner the graft. These findings suggest that placement of a GISC patch graft is no guarantee against tube exposure, and that better strategies are needed for preventing this complication.

To evaluate the effect of meibomian gland dysfunction (MGD) and friction-related disease (FRD) on the severity of dry eye disease (DED). Cross-sectional observational study. This study enrolled 449 patients with DED (63 men and 386 women; mean age, 62.6±15.7 years [range, 21-90 years]) for analysis. Subjective symptoms, the ocular surface, tear function, and the presence of MGD and FRD (superior limbic keratoconjunctivitis, conjunctivochalasis, and lid wiper epitheliopathy) were investigated. Schirmer value, tear film breakup time (TBUT), and keratoconjunctival score. We classified the participants into aqueous-deficient dry eye (ADDE; n = 231 [51.4%]) and short TBUT dry eye subtype (TBUT-DE; n = 109 [24.3%]) subgroups. The TBUT was shorter in patients with MGD than in those without MGD, whereas other ocular signs showed no difference (TBUT: MGD present, 1.97±1.02 seconds; MGD absent, 2.94±1.63 seconds [P < 0.001]; ADDE/MGD present, 1.94±1.08 seconds; ADDE/MGD absent, 2.77±1.61 seconds [P < 0.001]; short TBUT-DE/MGD present, 2.07±0.97 seconds; short TBUT-DE/MGD absent, 2.94±1.23 seconds [P = 0.01]). The ADDE patients with FRD showed a worse TBUT than ADDE patients without FRD (TBUT: ADDE/FRD present, 2.08±1.39 seconds; ADDE/FRD absent, 2.92±1.54 seconds; P < 0.001). This study showed associations between MGD, FRD, or both and ocular signs in DED. In the presence of MGD, FRD, or both, TBUT was significantly shortened regardless of the dry eye status or subtype.

Introduction Acute diarrheal disease (ADD) is a common cause of morbidity and mortality in children under 5 years of age. Understanding of the etiology of ADD is lacking in most low and middle income countries because reference laboratories detect limited number of pathogens. The objective of this study was to determine the feasibility to conduct a comprehensive case-control study to survey diarrheal pathogens among children with and without moderate-to-severe ADD. Materials and Methods Microbiology and molecular-based techniques were used to detect viral, bacterial, and parasitic enteropathogens. The study was conducted in Bucaramanga, Colombia, after Institutional Review Board approval was obtained. Results Ninety children less than 5 years of age were recruited after a written informed consent was obtained from parents or guardians. Forty-five subjects served as cases with ADD and 45 as controls. Thirty-six subjects out of 90 (40.0%) were positive for at least one enteropathogen, that is, 20 (44.4%) cases and 16 (35.5%) controls. Conclusions The three most common enteric pathogens were enteroaggregative E. coli (10.0%), Norovirus (6.7%), and Salmonella spp. (5.6%). The E. coli pathogens were 18.8% of all infections making them the most frequent pathogens. Half of ADD cases were negative for any pathogens. PMID:28855919

Acute aortic syndromes (AASs) are rare and severe cardiovascular emergencies with unspecific symptoms. For AASs, both misdiagnosis and overtesting are key concerns, and standardized diagnostic strategies may help physicians to balance these risks. D-dimer (DD) is highly sensitive for AAS but is inadequate as a stand-alone test. Integration of pretest probability assessment with DD testing is feasible, but the safety and efficiency of such a diagnostic strategy are currently unknown. In a multicenter prospective observational study involving 6 hospitals in 4 countries from 2014 to 2016, consecutive outpatients were eligible if they had ≥1 of the following: chest/abdominal/back pain, syncope, perfusion deficit, and if AAS was in the differential diagnosis. The tool for pretest probability assessment was the aortic dissection detection risk score (ADD-RS, 0-3) per current guidelines. DD was considered negative (DD-) if <500 ng/mL. Final case adjudication was based on conclusive diagnostic imaging, autopsy, surgery, or 14-day follow-up. Outcomes were the failure rate and efficiency of a diagnostic strategy for ruling out AAS in patients with ADD-RS=0/DD- or ADD-RS ≤1/DD-. A total of 1850 patients were analyzed. Of these, 438 patients (24%) had ADD-RS=0, 1071 patients (58%) had ADD-RS=1, and 341 patients (18%) had ADD-RS >1. Two hundred forty-one patients (13%) had AAS: 125 had type A aortic dissection, 53 had type B aortic dissection, 35 had intramural aortic hematoma, 18 had aortic rupture, and 10 had penetrating aortic ulcer. A positive DD test result had an overall sensitivity of 96.7% (95% confidence interval [CI], 93.6-98.6) and a specificity of 64% (95% CI, 61.6-66.4) for the diagnosis of AAS; 8 patients with AAS had DD-. In 294 patients with ADD-RS=0/DD-, 1 case of AAS was observed. This yielded a failure rate of 0.3% (95% CI, 0.1-1.9) and an efficiency of 15.9% (95% CI, 14.3-17.6) for the ADD-RS=0/DD- strategy. In 924 patients with ADD-RS ≤1/DD-, 3 cases of AAS were observed. This yielded a failure rate of 0.3% (95% CI, 0.1-1) and an efficiency of 49.9% (95% CI, 47.7-52.2) for the ADD-RS ≤1/DD- strategy. Integration of ADD-RS (either ADD-RS=0 or ADD-RS ≤1) with DD may be considered to standardize diagnostic rule out of AAS. URL: https://www.clinicaltrials.gov.

The Safety of Keppra as Adjunctive Therapy in Epilepsy (SKATE) study aimed to evaluate the safety and efficacy of levetiracetam (Keppra, LEV) as add-on therapy for refractory partial seizures in clinical practice. This Phase IV, 16-week, open-label study recruited patients > or =16-year old with treatment-resistant partial seizures. LEV (1000 mg/day) was added to a stable concomitant antiepileptic drug regimen. LEV dosage was adjusted based on seizure control and tolerability to a maximum of 3000 mg/day. 1541 patients (intent-to-treat population) were recruited including 1346 (87.3%) who completed the study and 77.0% who declared further continuing on LEV after the trial. Overall, 50.5% of patients reported at least one adverse event that was considered related to LEV treatment. The most frequently reported drug-related adverse events were mild-to-moderate somnolence, fatigue, dizziness and headache. Serious adverse events considered related to LEV occurred in 1.0% of patients. 7.5% of patients reported adverse events as the most important reason for study drug discontinuation. The median reduction from baseline in the frequency of all seizures was 50.2%; 15.8% of patients were seizure free; 50.1% had seizure frequency reduction of > or =50%. At the end of the study, 60.4% of patients were considered by the investigator to show marked or moderate improvement. There was a significant improvement in health-related quality of life as assessed with the QOLIE-10-P (total score increasing from 55.6 to 61.6; p<0.001). This community-based study suggests that LEV is well tolerated and effective as add-on therapy for refractory partial seizures in adults. These data provide supportive evidence for the safety and efficacy of LEV demonstrated in the pivotal Phase III placebo-controlled studies.

Study highlighting prices, i.e., the patients actually pay at ground level is important for interventions such as alternate procurement schemes or to expedite regulatory assessment of essential medicines for children. The present study was undertaken to study pricing and component analysis of few key essential medicines in Odisha state. Six child-specific medicines of different formulations were selected based on use in different disease condition and having widest pricing variation. Data were collected, entered, and analyzed in the price components data collection form of the World Health Organization-Health Action International (WHO-HAI) 2007 Workbook version 5 - Part II provided as part of the WHO/HAI methodology. The analysis includes the cumulative percent markup, total cumulative percent markup, and percent contribution of individual components to the final medicine price in both public and private sector of Odisha state. Add-on costs such as taxes, wholesale, and retail markups contribute substantially to the final price of medicines in private sector, particularly for branded-generic products. The largest contributor to add-on costs is at the level of retailer shop. Policy should be framed to achieve a greater transparency and uniformity of the pricing of medicines at different health sectors of Odisha.

Shannon entropy and particle decays

We deploy Shannon's information entropy to the distribution of branching fractions in a particle decay. This serves to quantify how important a given new reported decay channel is, from the point of view of the information that it adds to the already known ones. Because the entropy is additive, one can subdivide the set of channels and discuss, for example, how much information the discovery of a new decay branching would add; or subdivide the decay distribution down to the level of individual quantum states (which can be quickly counted by the phase space). We illustrate the concept with some examples of experimentally known particle decay distributions.

It is an impressive fact that many musicians can perform perfectly at an advanced age. Arthur Rubenstein played very demanding compositions of Chopin at the age of 88 and Andre Segovia at the age of 91 is still giving concerts on the classical guitar. Apparently, through practice very demanding neuromuscular activities can be maintained at advanced ages. Yet hours of daily "training" are behind these achievements. This review discusses some of the general aspects of training and their effects on function and health. As an overall goal it is more important to add life to years rather than add years to life.

To investigate whether vildagliptin add-on insulin therapy improves glycemic variations in patients with uncontrolled type 2 diabetes (T2D) compared to patients with placebo therapy. This was a 24-week, single-center, double-blind, placebo-controlled trial. Inadequately controlled T2D patients treated with insulin therapy were recruited between June 2012 and April 2013. The trial included a 2-week screening period and a 24-week randomized period. Subjects were randomly assigned to a vildagliptin add-on insulin therapy group (n = 17) or a matched placebo group (n = 16). Scheduled visits occurred at weeks 4, 8, 12, 16, 20, and 24. Continuous glucose monitoring (CGM) was performed before and at the endpoint of the study. A total of 33 subjects were admitted, with 1 patient withdrawing from the placebo group. After 24 weeks of therapy, HbA1c values were significantly reduced at the endpoint in the vildagliptin add-on group. CGM data showed that patients with vildagliptin add-on therapy had a significantly lower 24-h mean glucose concentration and mean amplitude of glycemic excursion (MAGE). At the endpoint of the study, patients in the vildagliptin add-on group had a significantly lower MAGE and standard deviation compared to the control patients during the nocturnal period (0000-0600). A severe hypoglycemic episode was not observed in either group. Vildagliptin add-on therapy to insulin has the ability to improve glycemic variations, especially during the nocturnal time period, in patients with uncontrolled T2D.

Abnormal pressure is an important factor that contributes to bone adaptation in the temporomandibular joint (TMJ). We determined the effect of the mitogen-activated protein kinases (MAPK) pathway on the pressure-induced synovial metaplasia procedure for the TMJ, both in vitro and in vivo. Synovial fibroblasts (SFs) were exacted from rat TMJs and exposed to different hydrostatic pressures. The protein extracts were analyzed to determine the activation of ERK1/2, JNK, and p38. Surgical anterior disc displacement (ADD) was also performed on Japanese rabbits, and the proteins of TMJ were isolated to analyze pressure-induced MAPK activation after 1, 2, 4, and 8 weeks. The results showed that the activation of ERK1/2 and JNK in SFs significantly changed with increasing hydrostatic pressure, whereas p38 activation did not change. Moreover, p38 was activated in animals 1 week after surgical ADD. The levels of p38 gradually increased after 2 and 4 weeks, and then slightly decreased but remained higher than in the control 8 weeks after surgical ADD. Nevertheless, JNK was rarely activated after the ADD treatment. Our findings suggest the involvement of MAPK activation in the pressure-induced synovial metaplasia procedure with pressure loading in TMJ.

The dubious assessment of gay, lesbian, and bisexual adolescents of add health.

PubMed

Savin-Williams, Ritch C; Joyner, Kara

2014-04-01

In this essay, we argue that researchers who base their investigations of nonheterosexuality derived from reports of romantic attractions of adolescent participants from Wave 1 of Add Health must account for their disappearance in future waves of data collection. The high prevalence of Wave 1 youth with either both-sex or same-sex romantic attractions was initially striking and unexpected. Subsequent data from Add Health indicated that this prevalence sharply declined over time such that over 70 % of these Wave 1 adolescents identified as exclusively heterosexual as Wave 4 young adults. Three explanations are proposed to account for the high prevalence rate and the temporal inconsistency: (1) gay adolescents going into the closet during their young adult years; (2) confusion regarding the use and meaning of romantic attraction as a proxy for sexual orientation; and (3) the existence of mischievous adolescents who played a "jokester" role by reporting same-sex attraction when none was present. Relying on Add Health data, we dismissed the first explanation as highly unlikely and found support for the other two. Importantly, these "dubious" gay, lesbian, and bisexual adolescents may have led researchers to erroneously conclude from the data that sexual-minority youth are more problematic than heterosexual youth in terms of physical, mental, and social health.

Functional neuroimaging studies are beginning to identify neuroanatomical correlates of various cognitive functions. This paper presents results relevant to several theories and phenomena of episodic memory, including component processes of episodic retrieval, encoding specificity, inhibition, item versus source memory, encoding-retrieval overlap, and the picture-superiority effect. Overall, by revealing specific activation patterns, the results provide support for existing theoretical views and they add some unique information which may be important to consider in future attempts to develop cognitive theories of episodic memory.

Participation, defined as a person's involvement in activities and roles, is a primary intervention goal in rehabilitation. To achieve client-centered practice, rehabilitation professionals need to go beyond objective accomplishment criteria and consider satisfaction with and the importance of participation in activities and roles. To our knowledge, no instrument considers accomplishment, satisfaction and importance of activities and roles, and allows numerical scoring and comparison. The objectives of this study were to modify the Assessment of Life Habits questionnaire (LIFE-Hm) to consider personalized satisfaction (satisfaction weighted by importance) with participation in activities and roles, and to: (1) examine its convergent validity with quality of life (QOL) and (2) compare the associations between QOL on the one hand and, satisfaction (LIFE-H) and personalized satisfaction (LIFE-Hm) with participation on the other. A descriptive cross-sectional study was conducted with 84 older adults, average age 76 years, with different functional autonomy levels. Quality of life was associated with personalized satisfaction for all categories of activities and roles (r = 0.45 to 0.75; p < 0.001). These associations differed significantly from the associations with satisfaction for the "housing", "mobility" and "responsibilities" categories (p = 0.04 to 0.0047). This study found good construct validity of the LIFE-Hm with QOL. Personalization can add value in achieving client-centered practice. Implications for Rehabilitation The LIFE-Hm becomes the first instrument available in English and French that allows comparison between individuals and informs rehabilitation professionals about the level of accomplishment, satisfaction and personalized satisfaction with participation in activities and roles. Personalized satisfaction can add value in achieving client-centered practice as it considers not only how satisfying activities and roles are for the person, but also the importance that these activities and roles have for her/him. The LIFE-Hm offers the advantage of systematically identifying activities and roles which are not satisfactory but are important for the client and have the potential to be improved (lower accomplishment level).

Pramipexole, a non-ergot dopamine D2/D3 receptor agonist, was investigated as an add on drug in advanced parkinsonian patients with motor fluctuations to assess efficacy, safety, and tolerance. Seventy eight patients of either sex with advanced Parkinson's disease and treatment complications such as motor fluctuations were enrolled into a double blind, placebo controlled, randomised, multicentre study (phase II) and assigned to add on treatment with pramipexole (n=34) versus placebo (n=44) to a previously stabilised antiparkinsonian medication (7 week dose titration interval, 4 week maintenance period). The primary end point of efficacy was the change from baseline in the total score of the unified Parkinson's disease rating scale (UPDRS) in the on "period" (2 hours after intake of study medication). Safety and tolerability were assessed on the basis of adverse events, vital signs, laboratory measurements, and ECG recordings. There was a significant improvement of the pramipexole group in UPDRS total scores, subscores part II, III (activities of daily living and motor examination), and IV (complications of therapy). Mean UPDRS total score decreased by 37.3% under pramipexole compared with 12.2% under placebo (p<0.001). Patients under pramipexole reported an overall reduction in "off" periods of 12%--resulting in 1.7 more hours "on" time a day--compared with an increase in "off" periods of 2% under placebo. There were no unexpected safety results. The adverse event profile disclosed a high tolerability. The most important adverse events under pramipexole were fatigue, dyskinesia, and vivid dreams. Pramipexole administration is an efficacious and well tolerated add on therapy in patients with advanced Parkinson's disease with an improvement in activities of daily living, motor function, and treatment associated complications.

The Integration of the Neurosciences, Child Public Health, and Education Practice: Hemisphere-Specific Remediation Strategies as a Discipline Partnered Rehabilitation Tool in ADD/ADHD.

Leisman, Gerry; Mualem, Raed; Machado, Calixto

2013-01-01

ADD/ADHD is the most common and most studied neurodevelopmental problem. Recent statistics from the U.S. Center for Disease Control state that 11% or approximately one out of every nine children in the US and one in five high school boys are diagnosed with ADD/ADHD. This number is thought to be increasing at around 15-20% per year. The US National Institute of Mental Health's Multi-modal Treatment Study has shown that medication has no long-term benefit for those with ADHD. To effectively address ADD/ADHD from within the framework of child public health, an interdisciplinary strategy is necessary that is based on a neuroeducational model that can be readily implemented on a large-scale within the educational system. This study is based on previous findings that ADD/ADHD children possess underactivity between sub-cortical and cortical regions. An imbalance of activity or arousal in one area can result in functional disconnections similar to that seen in split-brain patients. Since ADD/ADHD children exhibit deficient performance on tests developed to measure perceptual laterality, evidence of weak laterality or failure to develop laterality has been found across various modalities (auditory, visual, tactile). This has reportedly resulted in abnormal cerebral organization and ineffective cortical specialization necessary for the development of language and non-language function. This pilot study examines groups of ADD/ADHD and control elementary school children all of whom were administered all of the subtests of the Wechsler Individual Achievement Tests, the Brown Parent Questionnaire, and given objective performance measures on tests of motor and sensory coordinative abilities. Results measured after a 12-week remediation program aimed at increasing the activity of the hypothesized underactive right hemisphere function, yielded significant improvement of greater than 2 years in grade level in all domains except in mathematical reasoning. The treated group also displayed a significant improvement in behavior with a reduction in Brown scale behavioral scores. Non-treated control participants did not exhibit significant differences during the same 12 week period in academic measurements. Controls were significantly different from treatment participants in all domains after a 12-week period. The non-treatment group also demonstrated an increase in behavioral scores and increased symptoms of ADD/ADHD over the same time period when compared to the treated group. Results are discussed in the context of the concept of functional disconnectivity in ADD/ADHD children.

Evaluation of accuracy of linear regression models in predicting urban stormwater discharge characteristics.

PubMed

Madarang, Krish J; Kang, Joo-Hyon

2014-06-01

Stormwater runoff has been identified as a source of pollution for the environment, especially for receiving waters. In order to quantify and manage the impacts of stormwater runoff on the environment, predictive models and mathematical models have been developed. Predictive tools such as regression models have been widely used to predict stormwater discharge characteristics. Storm event characteristics, such as antecedent dry days (ADD), have been related to response variables, such as pollutant loads and concentrations. However it has been a controversial issue among many studies to consider ADD as an important variable in predicting stormwater discharge characteristics. In this study, we examined the accuracy of general linear regression models in predicting discharge characteristics of roadway runoff. A total of 17 storm events were monitored in two highway segments, located in Gwangju, Korea. Data from the monitoring were used to calibrate United States Environmental Protection Agency's Storm Water Management Model (SWMM). The calibrated SWMM was simulated for 55 storm events, and the results of total suspended solid (TSS) discharge loads and event mean concentrations (EMC) were extracted. From these data, linear regression models were developed. R(2) and p-values of the regression of ADD for both TSS loads and EMCs were investigated. Results showed that pollutant loads were better predicted than pollutant EMC in the multiple regression models. Regression may not provide the true effect of site-specific characteristics, due to uncertainty in the data.

To determine how adipocyte determination and differentiation factor 1 (ADD1), a gene involved in the determination of pork quality, is regulated in Laiwu and Large pigs, we used TaqMan fluorescence quantitative real-time polymerase chain reaction (FQ-PCR) to detect differential expression in the longissimus muscle of Laiwu (fatty) and Large White (lean) pigs. In this study, the ADD1 and GAPDH cDNA sequences were cloned using a T-A cloning assay, and the clone sequences were consistent with those deposited in GenBank. Thus, the target fragment was successfully recombined into the vector, and its integrity was maintained. The standard curve and regression equation were established through the optimized FQ-PCR protocol. The standard curve of porcine ADD1 and GAPDH cDNA was determined, and its linear range extension could reach seven orders of magnitudes. The results showed that this method was used to quantify ADD1 expression in the longissimus muscle of two breeds of pig, and was found to be accurate, sensitive, and convenient. These results provide information regarding porcine ADD1 mRNA expression and the mechanism of adipocyte differentiation, and this study could help in the effort to meet the demands of consumers interested in the maintenance of health and prevention of obesity. Furthermore, it could lead to new approaches in the prevention and clinical treatment of this disease.

18 F-flutemetamol uptake by brain tissue, measured by positron emission tomography (PET), is accepted by regulatory agencies like the Food and Drug Administration (FDA) and the European Medicine Agencies (EMA) for assessing amyloid load in people with dementia. Its added value is mainly demonstrated by excluding Alzheimer's pathology in an established dementia diagnosis. However, the National Institute on Aging and Alzheimer's Association (NIA-AA) revised the diagnostic criteria for Alzheimer's disease and the confidence in the diagnosis of mild cognitive impairment (MCI) due to Alzheimer's disease may be increased when using some amyloid biomarkers tests like 18 F-flutemetamol. These tests, added to the MCI core clinical criteria, might increase the diagnostic test accuracy (DTA) of a testing strategy. However, the DTA of 18 F-flutemetamol to predict the progression from MCI to Alzheimer's disease dementia (ADD) or other dementias has not yet been systematically evaluated. To determine the DTA of the 18 F-flutemetamol PET scan for detecting people with MCI at time of performing the test who will clinically progress to ADD, other forms of dementia (non-ADD) or any form of dementia at follow-up. The most recent search for this review was performed in May 2017. We searched MEDLINE (OvidSP), Embase (OvidSP), PsycINFO (OvidSP), BIOSIS Citation Index (Thomson Reuters Web of Science), Web of Science Core Collection, including the Science Citation Index (Thomson Reuters Web of Science) and the Conference Proceedings Citation Index (Thomson Reuters Web of Science), LILACS (BIREME), CINAHL (EBSCOhost), ClinicalTrials.gov (https://clinicaltrials.gov), and the World Health Organization International Clinical Trials Registry Platform (WHO ICTRP) (http://www.who.int/ictrp/search/en/). We also searched ALOIS, the Cochrane Dementia & Cognitive Improvement Group's specialised register of dementia studies (http://www.medicine.ox.ac.uk/alois/). We checked the reference lists of any relevant studies and systematic reviews, and performed citation tracking using the Science Citation Index to identify any additional relevant studies. No language or date restrictions were applied to the electronic searches. We included studies that had prospectively defined cohorts with any accepted definition of MCI at time of performing the test and the use of 18 F-flutemetamol scan to evaluate the DTA of the progression from MCI to ADD or other forms of dementia. In addition, we only selected studies that applied a reference standard for Alzheimer's dementia diagnosis, for example, National Institute of Neurological and Communicative Disorders and Stroke and the Alzheimer's Disease and Related Disorders Association (NINCDS-ADRDA) or Diagnostic and Statistical Manual of Mental Disorders-IV (DSM-IV) criteria. We screened all titles and abstracts identified in electronic-database searches. Two review authors independently selected studies for inclusion and extracted data to create two-by-two tables, showing the binary test results cross-classified with the binary reference standard. We used these data to calculate sensitivities, specificities, and their 95% confidence intervals. Two independent assessors performed quality assessment using the QUADAS-2 tool plus some additional items to assess the methodological quality of the included studies. Progression from MCI to ADD was evaluated in 243 participants from two studies. The studies reported data on 19 participants with two years of follow-up and on 224 participants with three years of follow-up. Nine (47.4%) participants converted at two years follow-up and 81 (36.2%) converted at three years of follow-up.There were concerns about participant selection and sampling in both studies. The index test domain in one study was considered unclear and in the second study it was considered at low risk of bias. For the reference standard domain, one study was considered at low risk and the second study was considered to have an unclear risk of bias. Regarding the domains of flow and timing, both studies were considered at high risk of bias. MCI to ADD;Progression from MCI to ADD at two years of follow-up had a sensitivity of 89% (95% CI 52 to 100) and a specificity of 80% (95% CI 44 to 97) by quantitative assessment by SUVR (n = 19, 1 study).Progression from MCI to ADD at three years of follow-up had a sensitivity of 64% (95% CI 53 to 75) and a specificity of 69% (95% CI 60 to 76) by visual assessment (n = 224, 1 study).There was no information regarding the other two objectives in this systematic review (SR): progression from MCI to other forms of dementia and progression to any form of dementia at follow-up. Due to the varying sensitivity and specificity for predicting the progression from MCI to ADD and the limited data available, we cannot recommend routine use of 18 F-flutemetamol in clinical practice. 18 F-flutemetamol has high financial costs; therefore, clearly demonstrating its DTA and standardising the process of the 18 F-flutemetamol modality is important prior to its wider use.

Dependent convergence: the importation of technological hazards by semiperipheral countries.

PubMed

Siqueira, C E; Levenstein, C

2000-01-01

This article complements the substantial body of literature produced over the last three decades on the export of hazards from developed countries to developing countries. After reviewing the central arguments proposed by this literature, the authors add to the debate by focusing on the role of national actors in the importation of these hazards, based on the experience of late 1970s' developments in the petrochemical industry in Brazil. The Brazilian case indicates that social struggles and/or interactions among actors in developing and developed nations determine to what extent hazardous technologies are imported without environmental controls and to what extent their hazardous effects are controlled by these nations. This study suggests that the future development of a more inclusive theory of export-import of hazardous technologies and products should take into account the dialectical relationship established between social actors internal to the exporting and importing countries.

To compare the effectiveness and cardiovascular safety of long-acting beta-agonists (LABAs) with those of leukotriene receptor antagonists (LTRAs) as add-on treatments in older adults with asthma already taking inhaled corticosteroids (ICSs). Retrospective cohort study. Medicare fee-for-service (FFS) claims (2009-10) for a 10% random sample of beneficiaries continuously enrolled in Parts A, B, and D in 2009. Medicare beneficiaries aged 66 and older continuously enrolled in FFS Medicare with Part D coverage with a diagnosis of asthma before 2009 treated exclusively with ICSs plus LABAs or ICSs plus LTRAs (N = 14,702). The augmented inverse propensity-weighted estimator was used to compare the effect of LABA add-on therapy with that of LTRA add-on therapy on asthma exacerbations requiring inpatient, emergency, or outpatient care and on cardiovascular (CV) events, adjusting for demographic characteristics, comorbidities, and county-level healthcare-access variables. The primary analysis showed that LTRA add-on treatment was associated with greater odds of asthma-related hospitalizations or emergency department visits (odds ratio (OR) = 1.4, P < .001), as well as outpatient exacerbations requiring oral corticosteroids or antibiotics (OR = 1.41, P < .001) than LABA treatment. LTRA add-on therapy was also less effective in controlling acute symptoms, as indicated by greater use of short-acting beta agonists (rate ratio = 1.58, P < .001). LTRA add-on treatment was associated with lower odds of experiencing a CV event than LABA treatment (OR = 0.86, P = .006). This study provides new evidence specific to older adults to help healthcare providers weigh the risks and benefits of these add-on treatments. Further subgroup analysis is needed to personalize asthma treatments in this high-risk population. © 2016, Copyright the Authors Journal compilation © 2016, The American Geriatrics Society.

Introduction Automated dose dispensing (ADD) is being introduced in several countries and the use of this technology is expected to increase as a growing number of elderly people need to manage their medication at home. ADD aims to improve medication safety and treatment adherence, but it may introduce new safety issues. This descriptive study provides insight into the nature and consequences of medication incidents related to ADD, as reported by healthcare professionals in community pharmacies and hospitals. Methods The medication incidents that were submitted to the Dutch Central Medication incidents Registration (CMR) reporting system were selected and characterized independently by two researchers. Main Outcome Measures Person discovering the incident, phase of the medication process in which the incident occurred, immediate cause of the incident, nature of incident from the healthcare provider's perspective, nature of incident from the patient's perspective, and consequent harm to the patient caused by the incident. Results From January 2012 to February 2013 the CMR received 15,113 incidents: 3,685 (24.4%) incidents from community pharmacies and 11,428 (75.6%) incidents from hospitals. Eventually 1 of 50 reported incidents (268/15,113 = 1.8%) were related to ADD; in community pharmacies more incidents (227/3,685 = 6.2%) were related to ADD than in hospitals (41/11,428 = 0.4%). The immediate cause of an incident was often a change in the patient's medicine regimen or relocation. Most reported incidents occurred in two phases: entering the prescription into the pharmacy information system and filling the ADD bag. Conclusion A proportion of incidents was related to ADD and is reported regularly, especially by community pharmacies. In two phases, entering the prescription into the pharmacy information system and filling the ADD bag, most incidents occurred. A change in the patient's medicine regimen or relocation was the immediate causes of an incident. PMID:25058321

Vildagliptin, a dipeptidyl peptidase-4 (DPP-4) inhibitor, is wildly used to treat type 2 diabetes mellitus (T2DM) with mono- or combination-therapy. We review two previously published open-label studies to extract insights on the long-term efficacy and safety of vildagliptin. Two studies were conducted in Japan to assess the efficacy and safety of vildagliptin as an add-on to other oral antidiabetes drugs (OADs) for 52 weeks. These studies were performed under the similar protocol in Japanese patients with T2DM who were inadequately controlled with OAD monotherapy [excluding other dipeptidyl peptidase-4 (DPP-4) inhibitors]. Addition of vildagliptin (50 mg twice daily) to other OAD monotherapy [sulfonylurea (SU), metformin, thiazolidinedione, alpha-glucosidase inhibitor and glinide] reduced glycated hemoglobin (HbA1c) levels by -0.64 %,-0.75 %,-0.92 %,-0.94 % and - 0.64 %, respectively, over 52 weeks of treatment. Overall, the incidence of hypoglycemia was low and was slightly higher in the add-on to SU treatment group compared with the other groups. The incidences of adverse events were comparable among the treatment groups, and vildagliptin was well-tolerated as add-on therapy to other OADs. The evidence from the two studies indicates that vildagliptin as an add-on therapy to other OADs is a clinically reasonable option for Japanese patients with T2DM who respond inadequately to other OAD monotherapy.

Greater reductions in glycated haemoglobin (HbA1c) with saxagliptin, a dipeptidyl peptidase-4 inhibitor, versus placebo add-on in patients with type 2 diabetes who had inadequate glycaemic control with dapagliflozin 10 mg/d plus metformin were demonstrated after 24 weeks of treatment. Results over 52 weeks of treatment were assessed in this analysis. Patients (mean baseline HbA1c 7.9%) receiving open-label dapagliflozin 10 mg/d plus metformin were randomized to double-blind saxagliptin 5 mg/d or placebo add-on. The adjusted mean change from baseline to week 52 in HbA1c was greater with saxagliptin than with placebo add-on -0.38% vs 0.05%; difference -0.42% (95% confidence interval -0.64, -0.20)]. More patients achieved the HbA1c target of <7% with saxagliptin than with placebo add-on (29% vs 13%), and fewer patients were rescued or discontinued the study for lack of glycaemic control with saxagliptin than with placebo add-on (19% vs 28%). Reductions from baseline in body weight (≤1.5 kg) occurred in both groups. Similar proportions of patients reported ≥1 adverse event with saxagliptin (58.2%) and placebo add-on (58.0%); no new safety signals were detected. Hypoglycaemia was infrequent in both treatment groups (≤2.5%), with no major episodes. The rate of urinary tract infections was similar in the saxagliptin and placebo add-on groups (7.8% vs 7.4%). The incidence of genital infections was 3.3% with saxagliptin versus 6.2% with placebo add-on. Triple therapy with saxagliptin add-on to dapagliflozin plus metformin for 52 weeks resulted in sustained improvements in glycaemic control without an increase in body weight or increased risk of hypoglycaemia. © 2016 John Wiley & Sons Ltd.

[Purpose] To investigate the sensitivity and specificity of a newly developed diagnostic tool, the Amer Dizziness Diagnostic Scale (ADDS), to evaluate and differentially diagnose vestibular disorder and to identify the strengths and weaknesses of the scale and its usefulness in clinical practice. [Subjects and Methods] Two hundred subjects of both genders (72 males, 128 females) aged between 18 to 60 (49.5±7.8) who had a history of vertigo and/or dizziness symptoms for this previous two weeks or less were recruited for the study. All subjects were referred by otolaryngologists, neurologists or family physicians in and around Jeddah, Kingdom of Saudi Arabia. On the first clinic visit, all the patients were evaluated once using the ADDS, following which they underwent routine testing of clinical signs and symptoms, audiometry, and a neurological examination, coupled with tests of Vestibulo-Ocular Reflex function, which often serves as the "gold standard" for determining the probability of a vestibular deficit. [Results] The results show that the ADDS strongly correlated with "true-positive" and "true-negative" responses for determining the probability of a vestibular disorder (r =0.95). A stepwise linear regression was conducted and the results indicate that the ADDS was a significant predictor of "true-positive" and "true-negative" responses in vestibular disorders (R(2) =0.90). Approximately 90% of the variability in the vestibular gold standard test was explained by its relationship to the ADDS. Moreover, the ADDS was found to have a sensitivity of 96% and a specificity of 96%. [Conclusion] This study showed that the Amer Dizziness Diagnostic Scale has high sensitivity and specificity and that it can be used as a method of differential diagnosis for patients with vestibular disorders.

Research on desistance and parenthood has yielded mixed results bringing into question whether, and for whom, parenthood matters. Scholarship has not fully explored the importance of residency status or patterns of desistance across a full range of neighborhood contexts, nor examined distinctions between temporary and long-term desistance. Our study uses data from the National Longitudinal Study of Adolescent to Adult Health (Add Health) to examine the association between parenthood residence and criminal desistance across levels of adolescent neighborhood poverty. Our findings demonstrate that parenthood has different meanings for desistance, depending on its duration, residency status, and neighborhood context. PMID:28133399

2016-12-01

Droplet-based microfluidics has recently emerged as a potential platform for studies of single-cell, directed evolution, and genetic sequencing. In droplet-based microfluidics, adding reagents into drops is one of the most important functions. In this paper, we develop a new self-triggered picoinjector to add controlled volumes of reagent into droplets at kilohertz rates. In the picoinjector, the reagent injecting is triggered by the coming droplet itself, without needing a droplet detection module. Meanwhile, the dosing volume can be precisely controlled. These features make the system more practical and reliable. We expect the new picoinjector will find important applications of droplet-based microfluidics in automated biological assay, directed evolution, enzyme assay, and so on.

Phylogeographic studies of aquatic insects provide valuable insights into mechanisms that shape the genetic structure of communities, yet studies that include broad geographic areas are uncommon for this group. We conducted a broad scale phylogeographic analysis of the least salmonfly Pteronarcella badia (Plecoptera) across western North America. We tested hypotheses related to mode of dispersal and the influence of historic climate oscillations on population genetic structure. In order to generate a larger mitochondrial data set, we used 454 sequencing to reconstruct the complete mitochondrial genome in the early stages of the project. Our analysis revealed high levels of population structure with several deeply divergent clades present across the sample area. Evidence from five mitochondrial genes and one nuclear locus identified a potentially cryptic lineage in the Pacific Northwest. Gene flow estimates and geographic clade distributions suggest that overland flight during the winged adult stage is an important dispersal mechanism for this taxon. We found evidence of multiple glacial refugia across the species distribution and signs of secondary contact within and among major clades. This study provides a basis for future studies of aquatic insect phylogeography at the inter-basin scale in western North America. Our findings add to an understanding of the role of historical climate isolations in shaping assemblages of aquatic insects in this region. We identified several geographic areas that may have historical importance for other aquatic organisms with similar distributions and dispersal strategies as P. badia. This work adds to the ever-growing list of studies that highlight the potential of next-generation DNA sequencing in a phylogenetic context to improve molecular data sets from understudied groups.

Predicting survival in AIDS: refining the model.

Hutchinson, S J; Brettle, R P; Gore, S M

We tested the validity of a previously-published AIDS staging system by examining AIDS-defining diseases (ADDs) and CD4 counts as prognostic factors for survival of the 248 AIDS patients in the Edinburgh City Hospital Cohort, of whom 56% were injecting drug-users (IDUs). Cox regression was used to model the proportionality of risk of death as the CD4 count declined and more ADDs were experienced, and dependence upon post-AIDS treatment. Using the system of Mocroft et al. (Lancet 1995; 346:12-17) to grade severity, our data were well enough modelled, but we suggest: (i) regrading of HIV dementia (RR 3.9, 95% CI 2.5-6.0), mainly attributed to the drug users, to a very severe ADD; (ii) reduction in risk from zidovudine (RR 0.7, 95% CI 0.5-1.0) during AIDS follow-up for patients starting treatment at or after AIDS diagnosis; (iii) improved management of first mild ADDs (from 1987-89 to 1994-95: 40% reduction in IDUs appearing with mild index diseases, and an approximate three-fold reduction in risk associated with a mild ADD). This study supports previous findings on the significance of ADDs and lowest CD4 count in predicting the lifetime of AIDS patients.

Cattle hepatocytes have already been used in veterinary in vitro toxicology, but their usefulness as a multi-parametric screening bioassay has never been investigated so far. In this study, cattle hepatocytes were incubated with illicit steroids/prohormones (boldenone, BOLD; its precursor boldione, ADD; dehydroepiandrosterone, DHEA; an association of ADD:BOLD), to characterize their transcriptional effects on drug metabolizing enzymes (DMEs) and related nuclear receptors (NRs), on cytochrome P450 3A (CYP3A) apoprotein and catalytic activity as well as to determine ADD and BOLD metabolite profiling. DHEA-exposed cells showed an up-regulation (higher than 2.5-fold changes) of three out of six NRs, CYP2B22 and CYP2C87; likewise, ADD:BOLD increased CYP4A11 mRNA levels. In contrast, a reduction of CYP1A1 and CYP2E1 mRNAs (lower than 2.5(-1)-fold changes) was noticed in ADD- and DHEA-incubated cells. No effect was noticed on CYP3A gene and protein expression, though an inhibition of 6β-, 2β- and 16β-hydroxylation of testosterone (higher than 60% of control cells) was observed in ADD- and BOLD-exposed cells. Finally, 17α-BOLD was the main metabolite extracted from hepatocyte media incubated with ADD and BOLD, but several mono-hydroxylated BOLD and ADD derivatives were detected, too. Collectively, cattle hepatocytes can represent a complementary screening bioassay, useful to characterize growth promoters metabolite profiling and their effects upon DMEs expression, regulation and function.

In an earlier continuous glucose monitoring (CGM)-based study, we reported that sitagliptin not only reduced 24-h mean glucose levels but also suppressed postprandial glucose increases, thus reducing the range of glycemic fluctuations in type 2 diabetes patients. In this study, we investigated whether sitagliptin might provide similar benefits in type 2 diabetes patients receiving insulin therapy by using CGM. The study included a total of 13 type 2 diabetes patients in whom stable glycemic control had been achieved after admission for glycemic control. Insulin regimens used included long-acting insulin preparations once daily in four patients and biphasic insulin preparations twice daily in nine, with the daily insulin dose being 19.0±12.7 U. During the CGM-based study, the patients were given insulin therapy alone on Days 1 and 2 and were given sitagliptin 50 mg/day as add-on treatment on Days 3-6, with their daily insulin doses maintained. The add-on treatment with sitagliptin led to significant decreases in 24-h mean glucose levels and SDs of 288 glucose levels measured by CGM for 24 h, as well as in the indices for magnitude of glucose variability and proportion of time in hyperglycemia, compared with insulin therapy alone (P<0.01), whereas there was no significant change seen in regard to the proportion of time in hypoglycemia with or without add-on treatment with sitagliptin. This CGM-based study clearly demonstrated that insulin therapy alone, whether with long-acting or biphasic insulin preparations, does not provide adequate glycemic control in type 2 diabetes patients. In contrast, add-on sitagliptin was shown to narrow the range of 24-h glucose fluctuations in these patients, suggesting that add-on treatment with sitagliptin is effective for postprandial glucose control in type 2 diabetes patients receiving insulin therapy.

Entecavir (ETV) is a potent inhibitor of hepatitis B viral replication, but long-term therapy may be required. We investigated whether adding on pegylated interferon (Peg-IFN) to ETV therapy enhances serological response rates. In this global investigator-initiated, open-label, multicenter, randomized trial, hepatitis B e antigen (HBeAg)-positive chronic hepatitis B (CHB) patients with compensated liver disease started on ETV monotherapy (0.5 mg/day) and were randomized in a 1:1 ratio to either Peg-IFN add-on therapy (180 µg/week) from week 24 to 48 (n = 85) or to continue ETV monotherapy (n = 90). Response was defined as HBeAg loss with HBV DNA <200 IU/mL at week 48. Responders discontinued ETV at week 72. All patients were followed until week 96. Response was achieved in 16 of 85 (19%) patients allocated to the add-on arm versus 9 of 90 (10%) in the monotherapy arm (P = 0.095). Adjusted for HBV DNA levels before randomized therapy, Peg-IFN add-on was significantly associated with response (odds ratio: 4.8; 95% confidence interval: 1.6-14.0; P = 0.004). Eleven (13%) of the add-on-treated patients achieved disease remission after ETV cessation versus 2 of 90 (2%) of those treated with monotherapy (P = 0.007), which was 79% (11 of 14) versus 25% (2 of 8) of those who discontinued ETV (P = 0.014). At week 96, 22 (26%) patients assigned add-on versus 12 (13%) assigned monotherapy achieved HBeAg seroconversion (P = 0.036). Peg-IFN add-on led to significantly more decline in hepatitis B surface antigen, HBeAg, and HBV DNA (all P < 0.001). Combination therapy was well tolerated. Although the primary endpoint was not reached, 24 weeks of Peg-IFN add-on therapy led to a higher proportion of HBeAg response, compared to ETV monotherapy. Add-on therapy resulted in more viral decline and appeared to prevent relapse after stopping ETV. Hence, Peg-IFN add-on therapy may facilitate the discontinuation of nucleos(t)ide analogs. © 2014 by the American Association for the Study of Liver Diseases.

Development of a new drug for the treatment of lung disease is a complex and time consuming process involving numerous disciplines of basic and applied sciences. During the 2015 Congress of the International Society for Aerosols in Medicine, a group of experts including aerosol scientists, physiologists, modelers, imagers, and clinicians participated in a workshop aiming at bridging the gap between basic research and clinical efficacy of inhaled drugs. This publication summarizes the current consensus on the topic. It begins with a short description of basic concepts of aerosol transport and a discussion on targeting strategies of inhaled aerosols to the lungs. It is followed by a description of both computational and biological lung models, and the use of imaging techniques to determine aerosol deposition distribution (ADD) in the lung. Finally, the importance of ADD to clinical efficacy is discussed. Several gaps were identified between basic science and clinical efficacy. One gap between scientific research aimed at predicting, controlling, and measuring ADD and the clinical use of inhaled aerosols is the considerable challenge of obtaining, in a single study, accurate information describing the optimal lung regions to be targeted, the effectiveness of targeting determined from ADD, and some measure of the drug's effectiveness. Other identified gaps were the language and methodology barriers that exist among disciplines, along with the significant regulatory hurdles that need to be overcome for novel drugs and/or therapies to reach the marketplace and benefit the patient. Despite these gaps, much progress has been made in recent years to improve clinical efficacy of inhaled drugs. Also, the recent efforts by many funding agencies and industry to support multidisciplinary networks including basic science researchers, R&D scientists, and clinicians will go a long way to further reduce the gap between science and clinical efficacy.

Transforming the patient experience in radiation therapy.

Jarvis, J Andrew

2003-01-01

Healthcare providers are paying more attention to behavioral neuroscience research that confirms what patients intuitively know: physical environments deeply influence one's sense of well being. Recognizing the importance of comforting environments, healthcare providers have been working with architects to design new facilities around the patient's experience. This doesn't mean that functional and technical considerations are unimportant; it's just that the patient's experience comes first. The patient is the most important user of a healthcare facility, and yet is the only user not sitting at the table during design meetings. For this reason, some healthcare providers work with their architects to develop the conceptual design from the patient's standpoint before seeking detailed staff input. Many indignities experienced by patients may be unwittingly imposed by caring and dedicated professional staff. Medical clutter, waste containers, water coolers, coffee makers, personal displays and decorations add up to create a distressing level of visual chaos. Departments are required to eliminate clutter and maintain a calm, pleasing environment. Employees appreciate a well-designed physical environment, too. Facilities that reduce stress for patients have the same impact on staff, alleviating tension as they care for patients. Putting the patient's experience first need not add capital construction cost to a project. Rearranging spaces for the sake of the patient adds no more to floor area. Added windows, skylights and interior finishes can add cost, but the incremental cost of these amenities is small in proportion to the total project cost. Facilities project powerful visual dues about an institution's values. Providers who carefully plan for a positive patient experience traditionally enjoy strong reputations and exceptional customer loyalty. These providers know that good design is not simply wrapping a pretty facade around a building or decorating the lobby. Good design is the careful orchestration of uplifting and encouraging experiences for patients throughout their entire visit. For providers who achieve this, architecture becomes evidence that they put their patients first.

Understanding the progression of prostate cancer to androgen-independence/castrate resistance and development of preclinical testing models are important for developing new prostate cancer therapies. This report describes studies performed 30 years ago, which demonstrate utility and shortfalls of xenografting to preclinical modeling. We subcutaneously implanted male nude mice with small prostate cancer fragments from transurethral resection of the prostate (TURP) from 29 patients. Successful xenografts were passaged into new host mice. They were characterized using histology, immunohistochemistry for marker expression, flow cytometry for ploidy status, and in some cases by electron microscopy and response to testosterone. Two xenografts were karyotyped by G-banding. Tissues from 3/29 donors (10%) gave rise to xenografts that were successfully serially passaged in vivo. Two, (UCRU-PR-1, which subsequently was replaced by a mouse fibrosarcoma, and UCRU-PR-2, which combined epithelial and neuroendocrine features) have been described. UCRU-PR-4 line was a poorly differentiated prostatic adenocarcinoma derived from a patient who had undergone estrogen therapy and bilateral castration after his cancer relapsed. Histologically, this comprised diffusely infiltrating small acinar cell carcinoma with more solid aggregates of poorly differentiated adenocarcinoma. The xenografted line showed histology consistent with a poorly differentiated adenocarcinoma and stained positively for prostatic acid phosphatase (PAcP), epithelial membrane antigen (EMA) and the cytokeratin cocktail, CAM5.2, with weak staining for prostate specific antigen (PSA). The line failed to grow in female nude mice. Castration of three male nude mice after xenograft establishment resulted in cessation of growth in one, growth regression in another and transient growth in another, suggesting that some cells had retained androgen sensitivity. The karyotype (from passage 1) was 43-46, XY, dic(1;12)(p11;p11), der(3)t(3:?5)(q13;q13), -5, inv(7)(p15q35) x2, +add(7)(p13), add(8)(p22), add(11)(p14), add(13)(p11), add(20)(p12), -22, +r4[cp8]. Xenografts provide a clinically relevant model of prostate cancer, although establishing serially transplantable prostate cancer patient derived xenografts is challenging and requires rigorous characterization and high quality starting material. Xenografting from advanced prostate cancer is more likely to succeed, as xenografting from well differentiated, localized disease has not been achieved in our experience. Strong translational correlations can be demonstrated between the clinical disease state and the xenograft model. © 2015 The Authors. The Prostate published by Wiley Periodicals, Inc.

Five graduate nursing students made a difference in the health of San Antonio citizens by conducting a community assessment as part of a standard clinical activity in their community health nursing course. The students and their professor were able to effect city-wide change for health protection and promotion through collaboration with the City of San Antonio Planning Department (CSAPD). By compiling information, linking organizations, and speaking before community groups about the importance of a fluoridated water supply, the students generated public interest and momentum, which resulted in a successful vote to add fluoride to the water supply. In addition, they were able to add to the assessment compiled by the Planning Department employees and increase the CSAPD's awareness of health concerns as an important area to assess within a community. The resulting assessment was more comprehensive than it would have been without the students' input. This use of collaboration provides a model other faculty may adopt for community assessment.

Recreational accidents in aquatic environments leading to death by drowning are quite frequent. Even if they do not usually require forensic investigation, they may provide useful information on the post mortem submersion interval (PMSI) and its relation with accumulated degree days (ADD). This is particularly useful to forensic science since most studies dealing with these matters rely mostly on animal carcasses as human analogues. In this work we report on a multiple drowning accident resulting in 6 victims. ADD was calculated based on the PMSI and water temperature during this period. PMSI varied between ∼7.4 days and ∼11.4 days, and estimated body drift from the accident site ranged from 0.5km to 8.0km. Surface water temperature in the accident area showed little variation during the PMSI (14.5-16.0°C). Estimated ADD varied between 115°C and 174°C, and between 104°C and 191°C when considering the cumulative lower (ADDmin) and upper (ADDmax) limits for ADD. We compare the results with recently published data on two similar cases, and suggest a range for ADD that can be assumed as necessary before body floatability is regain after a drowning accident.

Objective: Study highlighting prices, i.e., the patients actually pay at ground level is important for interventions such as alternate procurement schemes or to expedite regulatory assessment of essential medicines for children. The present study was undertaken to study pricing and component analysis of few key essential medicines in Odisha state. Methodology: Six child-specific medicines of different formulations were selected based on use in different disease condition and having widest pricing variation. Data were collected, entered, and analyzed in the price components data collection form of the World Health Organization-Health Action International (WHO-HAI) 2007 Workbook version 5 – Part II provided as part of the WHO/HAI methodology. The analysis includes the cumulative percent markup, total cumulative percent markup, and percent contribution of individual components to the final medicine price in both public and private sector of Odisha state. Results: Add-on costs such as taxes, wholesale, and retail markups contribute substantially to the final price of medicines in private sector, particularly for branded-generic products. The largest contributor to add-on costs is at the level of retailer shop. Conclusion: Policy should be framed to achieve a greater transparency and uniformity of the pricing of medicines at different health sectors of Odisha. PMID:28458429

Endometriosis is considered a chronic disease of women during their reproductive phase, which resembles many signs of malignancy. So far, therapeutic options for endometriosis-associated pain and infertility are unsatisfactory and often lead to recurrence of disease after termination of treatment. Angiogenesis seems to play an important role in the pathogenesis of endometriosis. The use of angiogenesis inhibitors may add an important new tool to well-established treatment schedules. Therefore, it is very important to thoroughly investigate the role of angiogenesis in endometriosis with respect to the female reproductive system.

The ability to accurately predict violence and other forms of serious antisocial behavior would provide important societal benefits, and there is substantial enthusiasm for the potential predictive accuracy of neuroimaging techniques. Here, we review the current status of violence prediction using actuarial and clinical methods, and assess the current state of neuroprediction. We then outline several questions that need to be addressed by future studies of neuroprediction if neuroimaging and other neuroscientific markers are to be successfully translated into public policy.

Oncology drugs combined with standard therapies (so-called add-on therapies, e.g. bevacizumab, palbociclib) often receive negative recommendations regarding the legitimacy of public financing, issued by government agencies responsible for their assessment, i.e. health technology assessment agencies. The aim of the study was to estimate the scale of the problem related to the reimbursement of add-on therapies used in the treatment of breast and genitourinary cancers in Poland and in the world. A multimodal approach was used to select add-on therapies. The reimbursement routes were analysed in 8 reference countries (Poland, Canada, England, Wales, France, Scotland, Australia, New Zealand). Based on a systematic search, data for breast and urogenital cancers were included. A total of 68 reimbursement documents for add-on therapies were identified. The analysis showed that in Poland, 20% of innovative schemes including add-on therapies should be reimbursed, while in the world the percentage of positive recommendations reaches 56%. It was observed that globally (including data for Poland) the chance for a favorable reimbursement recommendation for add-on therapies is 53%, with 29% being positive recommendations with limitations. In Poland, the majority of negative recommendations concern genitourinary cancers in comparison to breast cancer (83% vs 75%). Poland is at the head of the countries in terms of the number of negative reimbursement recommendations. Bearing in mind the world’s need of modifying the criteria for the evaluation of oncological therapies in the context of the possibility of their reimbursement, one should expect a change in the approach to the assessment of the legitimacy of financing innovative add-on therapies in Poland.

To investigate the prevalence of mandibular asymmetry (MA) within the symptomatic unilateral anterior disc displacement (ADD) patients, and analyze the influence TMJ factors of the MA severity. Patients aged under 20 years old with symptomatic unilateral ADD and asymptomatic volunteers with normal disc-condyle relationship diagnosed by magnetic resonance imaging (MRI) were included in this study. Posteroanterior cephalometric radiographs were taken to measure MA. Condylar height, disc length and disc displacement were measured by MRI. The prevalence and severity of MA were compared between the ADD and the control groups. The correlation between the severity of MA with the amount of condylar height shortage, disc deformity and distance of disc displacement were also evaluated within the ADD group. There were 165 cases in the unilateral ADD group, and 156 cases in the control group. One hundred and nineteen cases had MA which accounted 72.12% (119/165) in the ADD group; while in the control group, only 25.64% (40/156) exhibited MA. The mean horizontal menton deviation and condylar height shortage in the unilateral ADD group were significantly larger than that in the control group (5.62 mm vs. 4.19 mm; 3.14 mm vs. 1.32 mm, p < 0.01). The severity of MA was significantly correlated with the amount of disc displacement, disc deformity and condylar height shortage (correlation coefficient: 0.80, 0.70, and 0.82). MA is much more common and severe in young unilateral ADD patients. The severity of MA is correlated with the height of condyle and the status of the disc.

Transparent calculation methods are crucial when investigating trends in antimicrobial consumption over time and between populations. Until 2011, one single standardized method was applied when quantifying the Danish pig antimicrobial consumption with the unit "Animal Daily Dose" (ADD). However, two new methods for assigning values for ADDs have recently emerged, one implemented by DANMAP, responsible for publishing annual reports on antimicrobial consumption, and one by the Danish Veterinary and Food Administration (DVFA), responsible for the Yellow Card initiative. In addition to new ADD assignment methods, Denmark has also experienced a shift in the production pattern, towards a larger export of live pigs. The aims of this paper were to (1) describe previous and current ADD assignment methods used by the major Danish institutions and (2) to illustrate how ADD assignment method and choice of population and population measurement affect the calculated national antimicrobial consumption in pigs (2007-2013). The old VetStat ADD-values were based on SPCs in contrast to the new ADD-values, which were based on active compound, concentration and administration route. The new ADD-values stated by both DANMAP and DVFA were only identical for 48 % of antimicrobial products approved for use in pigs. From 2007 to 2013, the total number of ADDs per year increased by 9 % when using the new DVFA ADD-values, but decreased by 2 and 7 % when using the new DANMAP ADD-values or the old VetStat ADD-values, respectively. Through 2007 to 2013, the production of pigs increased from 26.1 million pigs per year with 18 % exported live to 28.7 million with 34 % exported live. In the same time span, the annual pig antimicrobial consumption increased by 22.2 %, when calculated using the new DVFA ADD-values and pigs slaughtered per year as population measurement (13.0 ADDs/pig/year to 15.9 ADDs/pig/year). However, when based on the old VetStat ADD values and pigs produced per year (including live export), a 10.9 % decrease was seen (10.6 ADDs/pig/year to 9.4 ADDs/pig/year). The findings of this paper clearly highlight that calculated national antimicrobial consumption is highly affected by chosen population measurement and the applied ADD-values.

The relationship of document and quantitative literacy with learning styles and selected personal variables for aerospace technology students at Indiana State University

NASA Astrophysics Data System (ADS)

Martin, Royce Ann

The purpose of this study was to determine the extent that student scores on a researcher-constructed quantitative and document literacy test, the Aviation Documents Delineator (ADD), were associated with (a) learning styles (imaginative, analytic, common sense, dynamic, and undetermined), as identified by the Learning Type Measure, (b) program curriculum (aerospace administration, professional pilot, both aerospace administration and professional pilot, other, or undeclared), (c) overall cumulative grade point average at Indiana State University, and (d) year in school (freshman, sophomore, junior, or senior). The Aviation Documents Delineator (ADD) was a three-part, 35 question survey that required students to interpret graphs, tables, and maps. Tasks assessed in the ADD included (a) locating, interpreting, and describing specific data displayed in the document, (b) determining data for a specified point on the table through interpolation, (c) comparing data for a string of variables representing one aspect of aircraft performance to another string of variables representing a different aspect of aircraft performance, (d) interpreting the documents to make decisions regarding emergency situations, and (e) performing single and/or sequential mathematical operations on a specified set of data. The Learning Type Measure (LTM) was a 15 item self-report survey developed by Bernice McCarthy (1995) to profile an individual's processing and perception tendencies in order to reveal different individual approaches to learning. The sample used in this study included 143 students enrolled in Aerospace Technology Department courses at Indiana State University in the fall of 1996. The ADD and the LTM were administered to each subject. Data collected in this investigation were analyzed using a stepwise multiple regression analysis technique. Results of the study revealed that the variables, year in school and GPA, were significant predictors of the criterion variables, document, quantitative, and total literacy, when utilizing the ADD. The variables learning style and program of study were found not to be significant predictors of literacy scores on the ADD instrument.

Mapping the MMPI-2-RF Specific Problems Scales Onto Extant Psychopathology Structures.

A main objective in developing the Minnesota Multiphasic Personality Inventory-2-Restructured Form (MMPI-2-RF; Ben-Porath & Tellegen, 2008 ) was to link the hierarchical structure of the instrument's scales to contemporary psychopathology and personality models for greater enhancement of construct validity. Initial evidence published with the Restructured Clinical scales has indicated promising results in that the higher order structure of these measures maps onto those reported in the extant psychopathology literature. This study focused on evaluating the internal structure of the Specific Problems and Interest scales, which have not yet been examined in this manner. Two large, mixed-gender outpatient and correctional samples were used. Exploratory factor analyses revealed consistent evidence for a 4-factor structure representing somatization, negative affect, externalizing, and social detachment. Convergent and discriminant validity analyses in the outpatient sample yielded a pattern of results consistent with expectations. These findings add further evidence to indicate that the MMPI-2-RF hierarchy of scales map onto extant psychopathology literature, and also add support to the notion that somatization and detachment should be considered important higher order domains in the psychopathology literature.

The C. elegans PRMT-3 possesses a type III protein arginine methyltransferase activity.

Protein arginine methylation is a common post-translational modification in eukaryotes that is catalyzed by a family of the protein arginine methyltransferases (PRMTs). PRMTs are classified into three types: type I and type II add asymmetrically and symmetrically dimethyl groups to arginine, respectively, while type III adds solely monomethyl group to arginine. However, although the enzymatic activity of type I and type II PRMTs have been reported, the substrate specificity and the methylation activity of type III PRMTs still remains unknown. Here, we report the characterization of Caenorhabditis elegans PRMT-2 and PRMT-3, both of which are highly homologous to human PRMT7. We find that these two PRMTs can bind to S-adenosyl methionine (SAM), but only PRMT-3 has methyltransferase activity for histone H2A depending on its SAM-binding domain. Importantly, thin-layer chromatographic analysis demonstrates that PRMT-3 catalyzes the formation of monomethylated, but not dimethylated arginine. Our study thus identifies the first type III PRMT in C. elegans and provides a means to elucidate the physiological significance of arginine monomethylation in multicellular organisms.

Adipocyte determination and differentiation-dependent factor 1/sterol regulatory element-binding protein-1c (ADD1/SREBP1c) is a major determinant of tissue differential lipogenic capacity in mammalian and avian species. The objectives of the present study were to focus on insertion-deletion polymorphism (indel) in the bovine ADD1/SREBP1c gene, and analyzing its effect on growth traits in a sample of 1035 cattle belonging to four Chinese cattle breeds. PCR-SSCP, DNA sequencing and agarose electrophoresis methods were used. The 778 bp PCR products of ADD1/SREBP1c gene exhibited three genotypes and two alleles were revealed: W and D. Frequencies of the W allele varied from 0.8651 to 1.000. The associations of the 84 bp indel mutation of ADD1/SREBP1c gene with growth traits of 265 Nanyang cows were analyzed. The animals with genotype WD had significantly higher birth weight, body weight, average daily gain than those with genotype WW at birth, 6-, 12-, 18-, and 24-month old (P < 0.05 or P < 0.01). These results suggest that the indel mutation of bovine ADD1/SREBP1c gene may influence the growth traits in cattle.

18 F-florbetaben uptake by brain tissue, measured by positron emission tomography (PET), is accepted by regulatory agencies like the Food and Drug Administration (FDA) and the European Medicine Agencies (EMA) for assessing amyloid load in people with dementia. Its added value is mainly demonstrated by excluding Alzheimer's pathology in an established dementia diagnosis. However, the National Institute on Aging and Alzheimer's Association (NIA-AA) revised the diagnostic criteria for Alzheimer's disease and confidence in the diagnosis of mild cognitive impairment (MCI) due to Alzheimer's disease may be increased when using some amyloid biomarkers tests like 18 F-florbetaben. These tests, added to the MCI core clinical criteria, might increase the diagnostic test accuracy (DTA) of a testing strategy. However, the DTA of 18 F-florbetaben to predict the progression from MCI to Alzheimer's disease dementia (ADD) or other dementias has not yet been systematically evaluated. To determine the DTA of the 18 F-florbetaben PET scan for detecting people with MCI at time of performing the test who will clinically progress to ADD, other forms of dementia (non-ADD), or any form of dementia at follow-up. The most recent search for this review was performed in May 2017. We searched MEDLINE (OvidSP), Embase (OvidSP), PsycINFO (OvidSP), BIOSIS Citation Index (Thomson Reuters Web of Science), Web of Science Core Collection, including the Science Citation Index (Thomson Reuters Web of Science) and the Conference Proceedings Citation Index (Thomson Reuters Web of Science), LILACS (BIREME), CINAHL (EBSCOhost), ClinicalTrials.gov (https://clinicaltrials.gov), and the World Health Organization International Clinical Trials Registry Platform (WHO ICTRP) (http://www.who.int/ictrp/search/en/). We also searched ALOIS, the Cochrane Dementia & Cognitive Improvement Group's specialised register of dementia studies (http://www.medicine.ox.ac.uk/alois/). We checked the reference lists of any relevant studies and systematic reviews, and performed citation tracking using the Science Citation Index to identify any additional relevant studies. No language or date restrictions were applied to electronic searches. We included studies that had prospectively defined cohorts with any accepted definition of MCI at time of performing the test and the use of 18 F-florbetaben scan to evaluate the DTA of the progression from MCI to ADD or other forms of dementia. In addition, we only selected studies that applied a reference standard for Alzheimer's dementia diagnosis, for example, the National Institute of Neurological and Communicative Disorders and Stroke and the Alzheimer's Disease and Related Disorders Association (NINCDS-ADRDA) or Diagnostic and Statistical Manual of Mental Disorders-IV (DSM-IV) criteria. We screened all titles and abstracts identified in electronic-database searches. Two review authors independently selected studies for inclusion and extracted data to create two-by-two tables, showing the binary test results cross-classified with the binary reference standard. We used these data to calculate sensitivities, specificities, and their 95% confidence intervals. Two independent assessors performed quality assessment using the QUADAS-2 tool plus some additional items to assess the methodological quality of the included studies. Progression from MCI to ADD, any other form of dementia, and any form of dementia was evaluated in one study (Ong 2015). It reported data on 45 participants at four years of follow-up; 21 participants met NINCDS-ADRDA criteria for Alzheimer's disease dementia at four years of follow-up, the proportion converting to ADD was 47% of the 45 participants, and 11% of the 45 participants met criteria for other types of dementias (three cases of FrontoTemporal Dementia (FTD), one of Dementia with Lewy body (DLB), and one of Progressive Supranuclear Palsy (PSP)). We considered the study to be at high risk of bias in the domains of the reference standard, flow, and timing (QUADAS-2). MCI to ADD; 18 F-florbetaben PET scan analysed visually: the sensitivity was 100% (95% confidence interval (CI) 84% to 100%) and the specificity was 83% (95% CI 63% to 98%) (n = 45, 1 study). Analysed quantitatively: the sensitivity was 100% (95% CI 84% to 100%) and the specificity was 88% (95% CI 68% to 97%) for the diagnosis of ADD at follow-up (n = 45, 1 study). MCI to any other form of dementia (non-ADD); 18 F-florbetaben PET scan analysed visually: the sensitivity was 0% (95% CI 0% to 52%) and the specificity was 38% (95% CI 23% to 54%) (n = 45, 1 study). Analysed quantitatively: the sensitivity was 0% (95% CI 0% to 52%) and the specificity was 40% (95% CI 25% to 57%) for the diagnosis of any other form of dementia at follow-up (n = 45, 1 study). MCI to any form of dementia; 18 F-florbetaben PET scan analysed visually: the sensitivity was 81% (95% CI 61% to 93%) and the specificity was 79% (95% CI 54% to 94%) (n = 45, 1 study). Analysed quantitatively: the sensitivity was 81% (95% CI 61% to 93%) and the specificity was 84% (95% CI 60% to 97%) for the diagnosis of any form of dementia at follow-up (n = 45, 1 study). Although we were able to calculate one estimation of DTA in, especially, the prediction of progression from MCI to ADD at four years follow-up, the small number of participants implies imprecision of sensitivity and specificity estimates. We cannot make any recommendation regarding the routine use of 18 F-florbetaben in clinical practice based on one single study with 45 participants. 18 F-florbetaben has high financial costs, therefore, clearly demonstrating its DTA and standardising the process of the 18 F-florbetaben modality are important prior to its wider use.

2015-02-01

Social rhythms, also known as daily routines (e.g. exercise, of school or work, recreation, social activities), have been identified as potential time cues to help to regulate the biological clock. Past research has shown links between regularity and healthy sleep. This study examined the regularity and frequency of daytime activities in a clinical insomnia population and a good sleeper comparison group. Participants (N = 69) prospectively monitored their sleep and daily activities for a 2-week period. Although participants with insomnia and good sleepers had similar levels of activity, relative to good sleepers, those with insomnia were less regular in their activities. Findings from this study add to the growing number of studies that highlight the relative importance of the regularity of daytime activities on sleep. Accordingly, future research should test treatment components that focus on regulating daytime activities, which would likely improve treatment outcomes.

The Treatment of Early Age Mania (TEAM) study evaluated lithium, risperidone, and divalproex sodium (divalproex) in children with bipolar I disorder who were naive to antimanic medication, or were partial or nonresponders to 1 of 3 study medications. This report evaluates the benefit of either an add-on or a switch of antimanic medications for an 8-week trial period in partial responders and nonresponders, respectively. TEAM is a randomized, controlled trial of individuals (N = 379) aged 6 to 15 years (mean ± SD = 10.2 ± 2.7 years) with DSM-IV bipolar I disorder (mixed or manic phase). Participants (n = 154) in this report were either nonresponders or partial responders to 1 of the 3 study medications. Nonresponders (n = 89) were randomly assigned to 1 of the other 2 antimanic medications and cross-tapered. Partial responders (n = 65) were randomly assigned to 1 of 2 other antimanic medications as an add-on to their initial medication. Adverse event (AE) rates are reported only for the add-on group. Response rate for children switched to risperidone (47.6%) was higher than for those switched to either lithium (12.8%; p = .005; number needed to treat [NNT] = 3; 95% CI = 1.71-9.09) or divalproex (17.2%; p = .03; NNT = 3; 95% CI = 1.79-20.10); response rate for partial responders who added risperidone (53.3%) was higher than for those who added divalproex (0%; p = .0002; NNT = 2; 95% CI = 1.27-3.56) and trended higher for lithium (26.7%; p = .07; NNT = 4). Reported AEs in the add-on group were largely consistent with the known AE profile for the second medication. Weight gain (kg) was observed for all add-on medications: lithium add-on (n = 29 of 30) = 1.66 ± 1.97; risperidone add-on (n = 15 of 15) = 2.8 ± 1.34; divalproex add-on (n = 19 of 20) = 1.42 ± 1.96. There was no evidence at the 5% significance level that the average weight gain was different by study medication for partial responders (p = .07, 1-way analysis of variance). Risperidone appears to be more useful than lithium or divalproex for children with bipolar I disorder and other comorbid conditions who are nonresponders or partial responders to an initial antimanic medication trial.

The aim was to determine the influence of meibomian gland dysfunction (MGD) and aqueous tear deficiency dry eye (ADDE) on the adhesive properties of the central cornea by means of optical coherence tomography (OCT), and to investigate the relationship between corneal adhesiveness and classical tear tests, as well as the reliability of results, in these lacrimal functional unit disorders. Prospective, case-control study. Twenty-eight patients with MGD and 27 patients with ADDE were studied. A group of 32 healthy subjects of similar age and gender distribution served as a control group. The adhesive properties of the anterior corneal surface were measured by OCT, based on the retention time of adhesion marker above it, in all participants. An excellent (≥5 minutes), borderline (within 3-5 minutes), fair (within 1-3 minutes) and poor (<1 minute) values of corneal adhesiveness were found, respectively, in 0%, 7.1%, 64.3% and 28.6% of MGD, in 0%, 7.4%, 63% and 29.6% of ADDE, and in 31.3%, 65.6%, 3.1% and 0% of healthy patients. The differences in time of corneal adhesiveness between MGD and healthy patients, as well as between ADDE and healthy patients, were found to be statistically significant (p<0.001; p<0.001; respectively). Conversely, no statistical significant differences between MGD and ADDE were found (p = 0.952). Data analysis revealed a statistically significant correlation between corneal adhesiveness and clinical tests of dry eye, as well as an excellent degree of inter-rater reliability and reproducibility for OCT measurements (p<0.001). ADDE and MGD share similar abnormalities on OCT imaging. Decreased adhesive properties of the anterior cornea were identified as a common feature of MGD and ADDE. This simple OCT approach may provide new clues into the mechanism and evaluation of dry eye syndrome.

The aim of present study is to compare the efficacy and safety of adding vildagliptin with sulfonylurea dose-increasing as an active comparator in patients who had inadequately controlled type 2 diabetes mellitus (T2DM) using metformin plus sulfonylurea in real clinical practice. Patients using metformin plus sulfonylurea were assigned to either vildagliptin add-on (50 mg twice a day, n=172) or sulfonylurea dose-increasing by 50% (n=172) treatment groups. The primary endpoint was a change in HbA(1c) after 24 weeks. The secondary endpoints were patients achieving HbA(1c)≤7.0% (53 mmol/mol) and changes in the fasting plasma glucose (FPG), 2-h postprandial glucose (2pp), lipid profiles, and urine albumin-to-creatinine ratio. Body weight and hypoglycemia were also investigated. The mean HbA(1c) at baseline was 8.6% (70 mmol/mol) in both groups. At week 24, the adjusted mean HbA(1c) levels decreased by -1.19% (-13.09 mmol/mol) with vildagliptin add-on and -0.46% (-5.06 mmol/mol) with sulfonylurea (P<0.001). Significantly more vildagliptin add-on patients achieved HbA(1c)≤7.0% (53 mmol/mol) than did sulfonylurea patients (40.1% vs. 7.9%; P<0.001). Greater reductions in FPG and 2pp were observed with vildagliptin add-on than with sulfonylurea (P<0.001). The vildagliptin add-on group exhibited no clinically relevant weight gain and had a lower incidence of hypoglycemia compared with the sulfonylurea group. Vildagliptin add-on therapy might be a suitable option for patients with T2DM that is controlled inadequately by metformin and sulfonylurea, based on its greater glucose control and better safety profile (ClinicalTrial.gov: NCT01099137).

To evaluate the safety and efficacy of elagolix vs. placebo and elagolix with low-dose E 2 /progestogen add-back therapy. Proof-of-concept, dose-ranging, multiple-cohort study. Clinics. Premenopausal women with fibroids and heavy menstrual bleeding (menstrual blood loss [MBL] >80 mL per cycle). Three months' treatment with elagolix alone: 100 mg twice daily (BID), 200 mg BID, 300 mg BID, 400 mg once daily (QD), or 600 mg QD (all but the 600 mg QD arm were placebo controlled); or elagolix plus add-back therapy: 200 mg BID plus continuous low-dose E 2 0.5 mg/norethindrone acetate 0.1 mg or elagolix 300 mg BID plus E 2 1 mg continuously and cyclical P 200 mg. Least-squares mean percentage change in MBL; adverse events (AEs). Mean age was 41.8 years; 73.8% were black; mean baseline MBL was 267 mL. Of randomized women (elagolix alone, n = 160; placebo, n = 50; elagolix with add-back therapy, n = 61), 228 of 271 completed the 3-month treatment period. The MBL percentage change from baseline to last 28 days was significantly greater with elagolix alone (range, -72% to -98%; dose-dependent reduction was highest with 300 mg BID) vs. placebo (range, -8% to -41%); mean percentage changes with add-back regimens were -80% to -85%. Overall AEs were dose independent (elagolix alone, 70.0%-81.3%) but lower with placebo (56.0%) and add-back regimens (55.6%-70.6%). Hot flush was the most common AE (elagolix alone, 45.5%-62.5%; placebo, 12.0%; add-back regimens, 18.5%-26.5%). Elagolix significantly reduced heavy menstrual bleeding in women with fibroids. Low-dose add-back regimens substantially reduced flushing. NCT01441635. Copyright © 2017 American Society for Reproductive Medicine. Published by Elsevier Inc. All rights reserved.

When the Heat Is On: The Effect of Temperature on Voter Behavior in Presidential Elections

PubMed Central

Van Assche, Jasper; Van Hiel, Alain; Stadeus, Jonas; Bushman, Brad J.; De Cremer, David; Roets, Arne

2017-01-01

Hot temperatures lead to heightened arousal. According to excitation transfer theory, arousal can increase both antisocial and prosocial behavior, depending on the context. Although many studies have shown that hot temperatures can increase antisocial behavior, very few studies have investigated the relationship between temperature and prosocial behavior. One important prosocial behavior is voting. We analyzed state-level data from the United States presidential elections (N = 761). Consistent with excitation transfer theory, which proposes that heat-induced arousal can transfer to other activities and strengthen those activities, changes in temperature and voter turnout were positively related. Moreover, a positive change in temperature was related to a positive change in votes for the incumbent party. These findings add to the literature on the importance of non-ideological and non-rational factors that influence voting behavior. PMID:28642723

Smith, W. W.

1981-01-01

The five major tasks of the program are reported. Task 1 is a literature search followed by selection and definition of seven generic spacecraft classes. Task 2 covers the determination and description of important disturbance effects. Task 3 applies the disturbances to the generic spacecraft and adds maneuver and stationkeeping functions to define total auxiliary propulsion systems requirements for control. The important auxiliary propulsion system characteristics are identified and sensitivities to control functions and large space system characteristics determined. In Task 4, these sensitivities are quantified and the optimum auxiliary propulsion system characteristics determined. Task 5 compares the desired characteristics with those available for both electrical and chemical auxiliary propulsion systems to identify the directions technology advances should take.

Lesbian health and the assumption of heterosexuality: an organizational perspective.

PubMed

Daley, Andrea

2003-01-01

This study used a qualitative research design to explore hospital policies and practices and the assumption of female heterosexuality. The assumption of heterosexuality is a product of discursive practices that normalize heterosexuality and individualize lesbian sexual identities. Literature indicates that the assumption of female heterosexuality is implicated in both the invisibility and marked visibility of lesbians as service users. This research adds to existing literature by shifting the focus of study from individual to organizational practices and, in so doing, seeks to uncover hidden truths, explore the functional power of language, and allow for the discovery of what we know and--equally as important--how we know.

Recently, myocardial blood flow quantitation with dynamic SPECT/CT has been reported to enhance the detection of coronary artery disease in human. This advance has created important clinical applications to coronary artery disease diagnosis and management for areas where myocardial perfusion PET tracers are not available. We present 2 clinical cases that undergone a combined test of 1-day rest/dipyridamole-stress dynamic SPECT and ECG-gated myocardial perfusion SPECT scans using an integrated imaging protocol and demonstrate that flow parameters are capable to conclude equivocal myocardial perfusion SPECT studies, therefore increasing diagnostic benefits to add value in making clinical decisions.

Stiripentol add-on therapy for focal refractory epilepsy.

PubMed

Brigo, Francesco; Igwe, Stanley C; Bragazzi, Nicola Luigi

2018-05-10

This is an updated version of the Cochrane review last published in 2015 (Issue 10). For nearly 30% of people with epilepsy, seizures are not controlled by current treatments. Stiripentol is a new antiepileptic drug (AED) that was developed in France and was approved by the European Medicines Agency (EMA) in 2007 for the treatment of Dravet syndrome as an adjunctive therapy with valproate and clobazam, with promising effects. To evaluate the efficacy and tolerability of stiripentol as add-on treatment for people with focal refractory epilepsy who are taking AEDs. For the latest update, we searched the following databases on 21 August 2017: Cochrane Epilepsy Specialized Register, CENTRAL , MEDLINE, ClinicalTrials.gov, and the WHO International Clinical Trials Registry Platform (ICTRP). We contacted Biocodex (the manufacturer of stiripentol) and epilepsy experts to identify published, unpublished and ongoing trials. Randomised, controlled, add-on trials of stiripentol in people with focal refractory epilepsy. Review authors independently selected trials for inclusion and extracted data. Outcomes investigated included 50% or greater reduction in seizure frequency, seizure freedom, adverse effects, treatment withdrawal and changes in quality of life. On the basis of our selection criteria, we included no new studies in the present review. Only one study was included from the earlier review (32 children with focal epilepsy). This study adopted a 'responder enriched' design and found no clear evidence of a reduction in seizure frequency (≥ 50% seizure reduction) (risk ratio (RR) 1.51, 95% confidence interval (CI) 0.81 to 2.82, low-quality evidence) nor evidence of seizure freedom (RR 1.18, 95% CI 0.31 to 4.43, low-quality evidence) when add-on stiripentol was compared with placebo. Stiripentol led to a greater risk of adverse effects considered as a whole (RR 2.65, 95% CI 1.08 to 6.47, low-quality evidence). When specific adverse events were considered, confidence intervals were very wide and showed the possibility of substantial increases and small reductions in risks of neurological (RR 2.65, 95% CI 0.88 to 8.01, low-quality evidence) or gastrointestinal adverse effects (RR 11.56, 95% CI 0.71 to 189.36, low-quality evidence). Researchers noted no clear reduction in the risk of study withdrawal (RR 0.66, 95% CI 0.30 to 1.47, low-quality evidence), which was high in both groups (35.0% in add-on placebo and 53.3% in stiripentol group, low-quality evidence). The external validity of this study was limited because only responders to stiripentol (i.e. patients experiencing a ≥ 50% decrease in seizure frequency compared with baseline) were included in the randomised, add-on, placebo-controlled, double-blind phase. Furthermore, carry-over and withdrawal effects probably influenced outcomes related to seizure frequency. Very limited information derived from the only included study shows that adverse effects considered as a whole seemed to occur significantly more often with add-on stiripentol than with add-on placebo. Since the last version of this review was published, we have found no new studies. Hence, we have made no changes to the conclusions of this update as presented in the initial review. We can draw no conclusions to support the use of stiripentol as add-on treatment for focal refractory epilepsy. Additional large, randomised, well-conducted trials are needed.

Boldenone (17-hydroxy-androsta-1,4-diene-3-one, Bol) and boldione (androst-1,4-diene-3,17-dione, ADD), are currently listed as exogenous anabolic steroids by the World Anti-Doping Agency. However, it has been reported that these analytes can be produced endogenously. Interestingly, only for Bol a comment is included in the list on its potential endogenous origin. In this study, the endogenous origin of ADD in human urine was investigated, and the potential influence of phytosterol consumption was evaluated. We carried out a 5-week in vivo trial with both men (n=6) and women (n=6) and measured alpha-boldenone, beta-boldenone, boldione, androstenedione, beta-testosterone and alpha-testosterone in their urine using gas chromatography coupled to multiple mass spectrometry (GC-MS-MS). The results demonstrate that endogenous ADD is sporadically produced at concentrations ranging from 0.751 ng mL(-1) to 1.73 ng mL(-1), whereas endogenous Bol could not be proven. We also tested the effect of the daily consumption of a commercially available phytosterol-enriched yogurt drink on the presence of these analytes in human urine. Results from this study could not indicate a relation of ADD-excretion with the consumption of phytosterols at the recommended dose. The correlations between ADD and other steroids were consistently stronger for volunteers consuming phytosterols (test) than for those refraining from phytosterol consumption (control). Excretion of AED, bT and aT did not appear to be dependent on the consumption of phytosterols. This preliminary in vivo trial indicates the endogenous origin of boldione or ADD in human urine, independent on the presence of any structural related analytes such as phytosterols.

Al Said, Abir; Cushen, Breda; Costello, Richard W

2017-01-01

The asthma syndrome has many manifestations, termed phenotypes, that arise by specific cellular and molecular mechanisms, termed endotypes. Understanding an individual’s asthma phenotype helps clinicians make rational therapeutic decisions while the understanding of endotypes has led to the development of specific precision medications. Allergic asthma is an example of an asthma phenotype and omalizumab, a monoclonal antibody that neutralizes serum immunoglobulin (Ig)E, is a specific targeted treatment which was developed as a result of an understanding of the endotype of allergic asthma. Omalizumab has been widely used in clinical practice in Europe for over a decade as an add-on therapy to treat patients who have severe refractory allergic asthma. Over this period, many centres have reported their experience with omalizumab as an add-on therapy in patients with severe asthma. These ‘real world’ clinical effectiveness studies have confirmed the benefits, cost-effectiveness and clinical utility of this medication. Combining the outcomes of both sources of research has yielded important insights that may benefit patients with severe asthma, clinicians who treat them, as well as the funding agencies that reimburse the cost of this medication. The purpose of this review is to describe how to identify and evaluate a patient with asthma for whom treatment with omalizumab may be of clinical and cost-effective benefit. The assessment and investigations used to confirm allergic asthma, the objective assessment of adherence to asthma therapy and the expected benefits of add-on omalizumab treatment are described.

There is limited information regarding the prevalence of presbyopia in different parts of the world. The add power and the prevalence of presbyopia by age and gender in general population of Shahroud, north of Iran, were studied. Population-based cross-sectional study. Using random cluster sampling, 6311 people from the 40- to 64-year-old population of Shahroud were invited. Of the invited population, 5190 individuals (82.2%) participated in the study. Presbyopia was defined as the correction of near vision to logMAR 1 (N8 point) with at least 1 D of add power. Near visual acuity of participants was evaluated with a logMAR chart at a distance of 40 cm. Mean add power in the age groups of 40-44, 45-49, 50-54, 55-59 and 60-64 years was 0.65, 1.30, 1.70, 1.87 and 2.08 D, respectively. For each 5-year increase in age, a 0.35 D increase in add power was noted. The prevalence of presbyopia was 58.15% (95% confidence interval: 56.46-59.84). Presbyopia was more prevalent in women (P < 0.001) and increased with ageing more in women than in men (P < 0.001). Furthermore, in the 60-64-year-old age group, 11% of men and 23% of women were not presbyopic. Compared with other reports, the add power in different age groups was 0.5 D less, and presbyopia was less prevalent. More than 50% of the over 45-year-old individuals were presbyopic and 17% of the over 60 individuals were free of this condition. © 2012 The Authors.

Singh, J Suzanne; Capozzoli, Michelle C; Dodd, Michael D; Hope, Debra A

2015-01-01

A growing theoretical and research literature suggests that trait and state social anxiety can predict attentional patterns in the presence of emotional stimuli. The current study adds to this literature by examining the effects of state anxiety on visual attention and testing the vigilance-avoidance hypothesis, using a method of continuous visual attentional assessment. Participants were 91 undergraduate college students with high or low trait fear of negative evaluation (FNE), a core aspect of social anxiety, who were randomly assigned to either a high or low state anxiety condition. Participants engaged in a free view task in which pairs of emotional facial stimuli were presented and eye movements were continuously monitored. Overall, participants with high FNE avoided angry stimuli and participants with high state anxiety attended to positive stimuli. Participants with high state anxiety and high FNE were avoidant of angry faces, whereas participants with low state and low FNE exhibited a bias toward angry faces. The study provided partial support for the vigilance-avoidance hypothesis. The findings add to the mixed results in the literature that suggest that both positive and negative emotional stimuli may be important in understanding the complex attention patterns associated with social anxiety. Clinical implications and suggestions for future research are discussed.

Purpose We aimed to assess the patient-reported outcome (PRO) and efficacy of add-on low-dose antimuscarinic therapy in over-active bladder (OAB) patients with suboptimal response to 4-week treatment with beta 3 agonist monotherapy (mirabegron, 50 mg). Materials and Methods We enrolled OAB patients with 4-week mirabegron (50 mg) treatment if the patients' symptoms improved, but not to a satisfactory extent (patient perception of bladder condition [PPBC] ≥4). Enrolled patients had 8-week low-dose antimuscarinics add-on therapy (propiverine HCl, 10 mg). Patients recorded 3-day voiding diary at screening, enrollment (after 4 weeks of mirabegron monotherapy) and after 8 weeks of add-on therapy. We assessed the change of PRO (PPBC) as a primary end point and the efficacy of add-on therapy (change of frequency, urgency, urinary urgency incontinence [UUI] based on voiding diary) as a secondary end point. Results Thirty patients (mean age, 62.3±12.8 years; mean symptom duration, 16.0±12.3 months) were finally enrolled in the study. The mean PPBC value was 4.3±0.4 after mirabegron monotherapy, and decreased to 3.2±1.0 after 8-week add-on therapy. The mean urinary frequency decreased from 10.1±3.1 to 8.8±3, the mean number of urgency episodes decreased from 3.6±1.6 to 1.8±1.2 and the number of urgency incontinence episodes decreased from 0.7±1.0 to 0.2±0.5 after add-on therapy. No patients had event of acute urinary retention and three patients complained of mild dry mouth after add-on therapy. Conclusions Add-on therapy of low-dose antimuscarinics exhibits good efficacy and safety in patients with suboptimal response after 4-week of mirabegron (50 mg) monotherapy. PMID:28681036

2011-01-01

The height at which smoke from a wildfire is injected into the atmosphere is an important parameter for climatology, because it determines how far the smoke can be transported. Using the MINX program to analyze MISR (Multi-angle Imaging Spectro-Radiometer) data, I digitized wildfire smoke plumes to add to an existing database of these heights for use by scientists studying smoke transport and plume dynamics. In addition to using MINX to do production digitizing of heights, I assisted in gathering lidar data for an ongoing validation of MINX and helped evaluate those data.

The results of investigations on the cognitive outcomes of adolescents exposed prenatally to radiation from Chernobyl are inconsistent. In 2005 through 2006, we assessed individuals exposed prenatally (N = 84) and controls (N = 94) using a broad neuropsychological test battery. Neuropsychological performance was significantly weaker in the 84 adolescents exposed prenatally compared to the 94 controls on measures of verbal working memory, verbal memory, and executive functioning when controlling for possible confounders. Our findings add new and important support to the hypothesis that the Chernobyl accident had a specific effect on the neuropsychological functioning of those exposed prenatally.

Sex-role identification and violent victimization: gender differences in the role of masculinity.

Although sex-role identification has been found to be associated with crime and delinquency, the link between sex-role identification and violent victimization has remained largely unexplored. Using the Add Health data, this study examines sex-role identification and its relationship to violent victimization. The findings suggest that masculinity increases the risk of violent victimization for males, but does not for females. Other differences in risk factors across gender were also found. These findings indicate that masculinity is an important construct in understanding the complexity of why some persons are violently victimized and others are not.

Post Traumatic Stress Disorder (PTSD) can be a debilitating problem in service members who have served in Iraq or Afghanistan. Virtual Reality Exposure Therapy (VRET) is one of the few interventions demonstrated in randomized controlled trials to be effective for PTSD in this population. There are theoretical reasons to expect that Virtual Reality (VR) adds to the effectiveness of exposure therapy, but there is also added expense and difficulty in using VR. Described is a trial comparing outcomes from VRET and a control exposure therapy (CET) protocol in service members with PTSD.

Depression is a serious mood disorder and is one of the most common mental illnesses. Despite the availability of several classes of antidepressants, a substantial percentage of patients are unresponsive to these drugs, which have a slow onset of action in addition to producing undesirable side effects. Some scientific evidence suggests that cyclodextrins (CDs) can improve the physicochemical and pharmacological profile of antidepressant drugs (ADDs). The purpose of this paper is to disclose current data technology prospects involving antidepressant drugs and cyclodextrins. Areas covered: We conducted a patent review to evaluate the antidepressive activity of the compounds complexed in CDs, and we analyzed whether these complexes improved their physicochemical properties and pharmacological action. The present review used 8 specialized patent databases for patent research, using the term 'cyclodextrin' combined with 'antidepressive agents' and its related terms. We found 608 patents. In the end, considering the inclusion criteria, 27 patents reporting the benefits of complexation of ADDs with CDs were included. Expert opinion: The use of CDs can be considered an important tool for the optimization of physicochemical and pharmacological properties of ADDs, such as stability, solubility and bioavailability.

A common reference-based indirect comparison meta-analysis of eslicarbazepine versus lacosamide as add on treatments for focal epilepsy.

Eslicarbazepine acetate (ESL) and lacosamide (LCM) have recently emerged as add-on treatments in patients with focal epilepsy experiencing seizures despite adequate monotherapy. Both drugs enhance slow inactivation of voltage-gated sodium channels. To date no randomized controlled trial (RCT) has directly compared ESL with LCM as add-on treatments for focal epilepsy. Our aim was to indirectly compare the efficacy of ESL and LCM used as add-on treatments in patients with focal epilepsy using common reference-based indirect comparison meta-analysis. We systematically searched RCTs in which ESL or LCM has been used as add-on treatment in patients with focal epilepsy and compared with placebo. Following outcomes were considered: ≥50% reduction in seizure frequency; seizure freedom; treatment withdrawal for any reason; ≥25% increase in seizure frequency. Random-effects Mantel-Haenszel meta-analyses were performed to obtain odds ratios (ORs) for the efficacy of ESL or LCM versus placebo. Adjusted indirect comparisons were then made between ESL and LCM using the obtained results, and comparing the minimum and the highest effective recommended daily dose of each drug. Eight studies were included. Indirect comparisons adjusted for dose-effect showed no difference between ESL and LCM for responder rate, seizure freedom, and withdrawal rates. We could not assess increase in seizure frequency due to lack of data. Indirect comparisons failed to find a significant difference in efficacy between add-on ESL and LCM in patients with focal epilepsy. Direct head-to-head clinical trials comparing ESL with LCM as add-on antiepileptic treatment are required to confirm these results. Copyright © 2016 Elsevier B.V. All rights reserved.

An early diagnosis of Alzheimer's disease (AD) confers many benefits. Several biomarkers from different information modalities have been proposed for the prediction of MCI to AD progression, where features extracted from MRI have played an important role. However, studies have focused almost exclusively in the morphological characteristics of the images. This study aims to determine whether features relating to the signal and texture of the image could add predictive power. Baseline clinical, biological and PET information, and MP-RAGE images for 62 subjects from the Alzheimer's Disease Neuroimaging Initiative were used in this study. Images were divided into 83 regions and 50 features were extracted from each one of these. A multimodal database was constructed, and a feature selection algorithm was used to obtain an accurate and small logistic regression model, which achieved a cross-validation accuracy of 0.96. These model included six features, five of them obtained from the MP-RAGE image, and one obtained from genotyping. A risk analysis divided the subjects into low-risk and high-risk groups according to a prognostic index, showing that both groups are statistically different (p-value of 2.04e-11). The results demonstrate that MRI features related to both signal and texture, add MCI to AD predictive power, and support the idea that multimodal biomarkers outperform single-modality biomarkers.

The absence of horns, known as the polled phenotype, is an economically important trait in modern yak husbandry, but the genomic structure and genetic basis of this phenotype have yet to be discovered. Here, we conducted a genome-wide association study with a panel of 10 horned and 10 polled yaks using whole genome sequencing. We mapped the POLLED locus to a 200-kb interval, which comprises three protein-coding genes. Further characterization of the candidate region showed recent artificial selection signals resulting from the breeding process. We suggest that expressional variations rather than structural variations in protein probably contribute to the polled phenotype. Our results not only represent the first and important step in establishing the genomic structure of the polled region in yak, but also add to our understanding of the polled trait in bovid species.

Measles supplementary immunization activities (SIAs) offer children in countries with weaker immunization delivery systems like India a second opportunity for measles vaccination. They could also provide a platform to deliver additional interventions, but the feasibility and acceptability of including add-ons is uncertain. We surveyed Indian programme officers involved in the current (2010-2012) measles SIAs concerning opportunities and challenges of using SIAs as a delivery platform for other maternal and child health interventions. Respondents felt that an expanded SIA strategy including add-ons could be of great value in improving access and efficiency. They viewed management challenges, logistics, and safety as the most important potential barriers. They proposed that additional interventions be selected using several criteria, of which importance of the health problem, safety, and contribution to health equity figured most prominently. For children, they recommended inclusion of basic interventions to address nutritional deficiencies, diarrhoea and parasites over vaccines. For mothers, micronutrient interventions were highest ranked. Copyright © 2012 Elsevier Ltd. All rights reserved.

Many patients with epilepsy are treated with antiepileptic drug (AED) polytherapy. Several factors influence the choice of early add-on therapy, and deciding on the most appropriate drug can be difficult. This study aimed to assess the efficacy and tolerability of lacosamide as early add-on therapy in patients with partial-onset seizures. REALLY (REtrospective study of lAcosamide as earLy add-on aLong one Year) was a multicenter, retrospective, 1-year, real-life study. Patients included were aged older than 16 years, had partial-onset seizures, and were treated with lacosamide as add-on therapy after one or two prior AEDs. Data were collected retrospectively from clinical records. The primary study objective was to assess the efficacy of lacosamide over 12 months (seizure-free and responder rates), and the secondary objective was to assess the tolerability of lacosamide at 3, 6, and 12 months [adverse events (AEs) and discontinuation]. One hundred and ninety-nine patients were enrolled in the study; 89 patients (44.7 %) had tried one AED and 110 patients (55.3 %) had tried two AEDs before lacosamide. At 12 months, the proportion of patients who were seizure free was 44.9 %, and 76 % of patients were responders. The seizure-free rate at 12 months for patients who had previously received one or two AEDs was 58 and 34.3 %, and the responder rate at 12 months was 83.0 and 70.4 %, respectively. The AE rate was 21.5 % at 3 months, 27.1 % at 6 months, and 31.2 % at 12 months, with 7.0 % of patients discontinuing treatment because of an AE. The most common AE reported was dizziness (11.6 %). Cryptogenic epilepsy, a higher number of prior AEDs, and the use of a sodium channel blocker at onset were associated with a worse outcome. The number of concomitant AEDs decreased over 1 year (Z = 5.89; p < 0.001). Twenty-two patients were converted to lacosamide monotherapy with at least one evaluation ≥6 months from the beginning of monotherapy conversion. Lacosamide was effective and well tolerated as early add-on treatment in patients who had received one or two previous AEDs.

Niche evolution and diversification in a Neotropical radiation of birds (Aves: Furnariidae).

PubMed

Seeholzer, Glenn F; Claramunt, Santiago; Brumfield, Robb T

2017-03-01

Rapid diversification may be caused by ecological adaptive radiation via niche divergence. In this model, speciation is coupled with niche divergence and lineage diversification is predicted to be correlated with rates of niche evolution. Studies of the role of niche evolution in diversification have generally focused on ecomorphological diversification but climatic-niche evolution may also be important. We tested these alternatives using a phylogeny of 298 species of ovenbirds (Aves: Furnariidae). We found that within Furnariidae, variation in species richness and diversification rates of subclades were best predicted by rate of climatic-niche evolution than ecomorphological evolution. Although both are clearly important, univariate regression and multivariate model averaging more consistently supported the climatic-niche as the best predictor of lineage diversification. Our study adds to the growing body of evidence, suggesting that climatic-niche divergence may be an important driver of rapid diversification in addition to ecomorphological evolution. However, this pattern may depend on the phylogenetic scale at which rate heterogeneity is examined. © 2017 The Author(s). Evolution © 2017 The Society for the Study of Evolution.

Polarimetry of X-rays and messengers of High Energy phenomena

Astrophysics of High Energies has been historically based on radio, X-ray and γ -ray data. Understanding the mechanism and the site of acceleration of Cosmic Rays, has been probably the most important goal of this discipline. Recently high energy neutrinos and gravitational waves have shown up as new messengers and we expect a major role from X-ray observations, to understand the nature and location of the emitters. In fact X-rays have been for more than half a century the driver to study the Violent Universe. Yet one feature of this messengers, the Polarimetry, is still totally unexploited. Within a few years, a mission will add two important parameters to understand the physical context of high energy phenomena, namely the amount and angle of X-ray polarimetry.

The genomes of fungi provide an important resource to resolve issues pertaining to their taxonomy, biology, and evolution. The genomes of Amanita jacksonii, Ceratocystis albifundus, a Fusarium circinatum variant, Huntiella omanensis, Leptographium procerum, Sclerotinia echinophila, and Rutstroemia sydowiana are presented in this genome announcement. These seven genomes are from a number of fungal pathogens and economically important species. The genome sizes range from 27 Mb in the case of Ceratocystis albifundus to 51.9 Mb for Rutstroemia sydowiana. The latter also encodes for a predicted 17 350 genes, more than double that of Ceratocystis albifundus. These genomes will add to the growing body of knowledge of these fungi and provide a value resource to researchers studying these fungi.

Responsive biomaterials play important roles in imaging, diagnostics, and therapeutics. Polymeric nanoparticles (NPs) containing hydrophobic and hydrophilic segments are one class of biomaterial utilized for these purposes. The incorporation of luminescent molecules into NPs adds optical imaging and sensing capability to these vectors. Here we report on the synthesis of dual-emissive, pegylated NPs with “stealth”-like properties, delivered intravenously (IV), for the study of tumor accumulation. The NPs were created by means of stereocomplexation using a methoxy-terminated polyethylene glycol and poly(D-lactide) (mPEG-PDLA) block copolymer combined with iodide-substituted difluoroboron dibenzoylmethane-poly(L-lactide) (BF2dbm(I)PLLA). Boron nanoparticles (BNPs) were fabricated in two different solvent compositions to study the effects on BNP size distribution. The physical and photoluminescent properties of the BNPs were studied in vitro over time to determine stability. Finally, preliminary in vivo results show that stereocomplexed BNPs injected IV are taken up by tumors, an important prerequisite to their use as hypoxia imaging agents in preclinical studies.

Several studies suggest that a healthy diet with high emphasis on nutritious, low-energy components such as fruits, vegetables, and seafood tends to be more costly for consumers. Derived from the ideas from the New Nordic Cuisine--and inspired by the Mediterranean diet, the New Nordic Diet (NND) has been developed as a palatable, healthy and sustainable diet based on products from the Nordic region. The objective of the study is to investigate economic consequences for the consumers of the NND, compared with an Average Danish Diet (ADD). Combine quantity data from a randomized controlled ad libitum dietary 6 month intervention for central obese adults (18-65 years) and market retail price data of the products consumed in the intervention. Adjust consumed quantities to market price incentives using econometrically estimated price elasticities. Average daily food expenditure of the ADD as represented in the unadjusted intervention (ADD-i) amounted to 36.02 DKK for the participants. The daily food expenditure in the unadjusted New Nordic Diet (NND-i) costs 44.80 DKK per day per head, and is hence about 25% more expensive than the Average Danish Diet (or about 17% when adjusting for energy content of the diet). Adjusting for price incentives in a real market setting, the estimated cost of the Average Danish Diet is reduced by 2.50 DKK (ADD-m), compared to the unadjusted ADD-i diet, whereas the adjusted cost of the New Nordic Diet (NND-m) is reduced by about 3.50 DKK, compared to the unadjusted NND-i. The distribution of food cost is however much more heterogeneous among consumers within the NND than within the ADD. On average, the New Nordic Diet is 24-25 per cent more expensive than an Average Danish Diet at the current market prices in Denmark (and 16-17 per cent, when adjusting for energy content). The relatively large heterogeneity in food costs in the NND suggests that it is possible to compose an NND where the cost exceeds that of ADD by less than the 24-25 per cent.

Many patients with post-traumatic stress disorder (PTSD) achieve but partial remission with current treatments. Patients with unremitted PTSD show high rates of substance abuse. Marijuana is often used as compassion add-on therapy for treatment-resistant PTSD. This open-label study evaluates the tolerance and safety of orally absorbable Δ(9)-tetrahydrocannabinol (THC) for chronic PTSD. Ten outpatients with chronic PTSD, on stable medication, received 5 mg of Δ(9)-THC twice a day as add-on treatment. There were mild adverse effects in three patients, none of which led to treatment discontinuation. The intervention caused a statistically significant improvement in global symptom severity, sleep quality, frequency of nightmares, and PTSD hyperarousal symptoms. Orally absorbable Δ(9)-THC was safe and well tolerated by patients with chronic PTSD.

Taking evolution seriously in political science.

PubMed

Lewis, Orion; Steinmo, Sven

2010-09-01

In this essay, we explore the epistemological and ontological assumptions that have been made to make political science "scientific." We show how political science has generally adopted an ontologically reductionist philosophy of science derived from Newtonian physics and mechanics. This mechanical framework has encountered problems and constraints on its explanatory power, because an emphasis on equilibrium analysis is ill-suited for the study of political change. We outline the primary differences between an evolutionary ontology of social science and the physics-based philosophy commonly employed. Finally, we show how evolutionary thinking adds insight into the study of political phenomena and research questions that are of central importance to the field, such as preference formation.

Experimental Approaches for Solution X-Ray Scattering and Fiber Diffraction

Irving, T. C.

2008-01-01

X-ray scattering and diffraction from non-crystalline systems have gained renewed interest in recent years, as focus shifts from the structural chemistry information gained by high-resolution studies to the context of structural physiology at larger length scales. Such techniques permit the study of isolated macromolecules as well as highly organized macromolecular assemblies as a whole under near-physiological conditions. Time-resolved approaches, made possible by advanced synchrotron instrumentation, add a critical dimension to many of these investigations. This article reviews experimental approaches in non-crystalline x-ray scattering and diffraction that may be used to illuminate important scientific questions such as protein/nucleic acid folding and structure-function relationships in large macromolecular assemblies.

2012-01-01

Despite important connections between religion and military action throughout world history, scholars have seldom explored the association between religiosity and military enlistment. Using data from the National Longitudinal Study of Adolescent Health (Add Health), we used a person-oriented analysis to categorize young men according to patterns of adolescent religious involvement. Youth indentified as “highly religious evangelical” are more likely to enlist in the military compared to their “highly religious non-evangelical” and “non-religious” counterparts; however, these findings hold only for those young men without college experience. These findings are discussed along with study limitations and promising directions for future research. PMID:22984296

In this paper we have studied the thermal fluctuation patterns occurring at the ocular surface of the left and right eyes for aqueous deficient dry eye (ADDE) patients and control subjects by thermal imaging. We conducted our experiment on 42 patients (84 eyes) with aqueous deficient dry eyes and compared with 36 healthy volunteers (72 eyes) without any history of ocular surface disorder. Schirmer's test, Tear Break-up Time, tear Meniscus height and fluorescein staining tests were conducted. Ocular surface temperature measurement was done, using an FL-IR thermal camera and thermal fluctuation in left and right eyes was calculated and analyzed using MATLAB. The time series containing the sum of squares of the temperature fluctuation on the ocular surface were compared for aqueous deficient dry eye and control subjects. Significant statistical difference between the fluctuation patterns for control and ADDE was observed (p < 0.001 at 95% confidence interval). Thermal fluctuations in left and right eyes are significantly correlated in controls but not in ADDE subjects. The possible origin of such correlation in control and lack of correlation in the ADDE subjects is discussed in the text. Copyright © 2014 Elsevier Ltd. All rights reserved.

Religion and Early Marriage in the United States: Evidence from the Add Health Study.

Uecker, Jeremy

2014-06-01

Early marriage has important consequences for individuals in the United States. Several studies have linked religion to early marriage but have not examined this relationship in depth. Using data from Waves 1, 3, and 4 of the National Longitudinal Study of Adolescent Health, I conduct multilevel event-history analysis to examine how religion, at both individual and contextual levels, is associated with early marriage. Further, I test mediators of the religion-early marriage relationship. I find significant variation in early marriage by religious tradition, religious service attendance, religious salience, belief in scriptural inerrancy, and religious context in high school. The individual religious effects-but not the school context effects-are explained in part by differential attitudes toward marriage and cohabitation.

The New Nordic Diet (NND) has induced weight loss in a 26-week controlled intervention. We aim to investigate whether high compliance and satisfaction can be maintained after the active intervention is discontinued thereby maintaining the health effects. After 26 weeks of intervention with NND or Average Danish Diet (ADD), 147 participants (mean age 43 years and mean BMI 29.1 kg/m²) were followed for further 52 weeks. All participants were encouraged to follow NND but without further guidance. The study is registered with ClinicalTrials.gov, study id NCT01195610. One hundred and ten participants (75%) completed the follow-up. Among participants previously randomised to NND (NND group), dietary compliance and satisfaction decreased from 4.3 to 3.0 and from 4.8 to 4.0, respectively (both p < 0.0001) (1-5 point scale). Among those originally randomised to ADD (ADD group), satisfaction with NND was significantly higher than with ADD during follow-up (3.3 vs. 2.5, p = 0.026). Weight losses during intervention of -6.2 kg and -3.0 kg were followed by regains of 4.6 kg (SE 0.5) and 1.1 kg (SE 0.7) for the NND group and ADD group, respectively [adjusted difference; mean (95 % CI): 1.8 kg (0.1-3.4), p = 0.041]. Across diet groups, every 1 score higher in compliance with NND was associated with 0.90 kg less body weight regain (p = 0.026) and those who increased physical activity regained 3.4 kg less compared to those who did not (p < 0.0001). NND provides higher satisfaction, and body weight regain is reduced with higher compliance with NND and increased physical activity.

A feasibility study was conducted to assess the applicability of an existing parabolic analysis (ADD-Axisymmetric Diffuser Duct), developed previously for subsonic viscous internal flows, to mixed supersonic/subsonic flows with heat addition simulating a SCRAMJET combustor. A study was conducted with the ADD code modified to include additional convection effects in the normal momentum equation when supersonic expansion and compression waves were present. It is concluded from the present study that for the class of problems where strong viscous/inviscid interactions are present a global iteration procedure is required.

Depression and anxiety are associated with poor recovery in coronary artery bypass graft (CABG) patients, but little is known about predictors of depression and anxiety symptoms. We tested the prospective association between attachment orientation, and symptoms of depression and anxiety in CABG patients, 6-8 weeks, and 12 months following surgery. One hundred and fifty-five patients who were undergoing planned CABG surgery were recruited. Patients completed questionnaires measuring attachment, depression, and anxiety prior to surgery, then 6-8 weeks, and 12 months after surgery. Attachment anxiety predicted symptoms of depression and anxiety at both follow-up time points, whereas attachment avoidance was not associated with depression or anxiety symptoms. The findings remained significant when controlling for baseline mood scores, social support, demographic, and clinical risk factors. These results suggest that attachment anxiety is associated with short-term and long-term depression and anxiety symptoms following CABG surgery. These results may offer important insight into understanding the recovery process in CABG surgery. Statement of contribution What is already known on this subject? Depression and anxiety symptoms are twice more likely to occur in coronary artery bypass graft (CABG) populations than in any other medical group. Depression and anxiety are associated with poor recovery following cardiac surgery. Predictors of depression and anxiety in CABG patients have been underexplored. What does this study add? This study highlights the importance of close interpersonal relationships on health. Attachment anxiety was prospectively associated with higher levels of depression and anxiety. These results add to understanding mechanisms linked to recovery following CABG. © 2016 The Authors.

Add-on unidirectional elastic metamaterial plate cloak

PubMed Central

Lee, Min Kyung; Kim, Yoon Young

2016-01-01

Metamaterial cloaks control the propagation of waves to make an object invisible or insensible. To manipulate elastic waves in space, a metamaterial cloak is typically embedded in a base system that includes or surrounds a target object. The embedding is undesirable because it structurally weakens or permanently alters the base system. In this study, we propose a new add-on metamaterial elastic cloak that can be placed over and mechanically coupled with a base structure without embedding. We designed an add-on type annular metamaterial plate cloak through conformal mapping, fabricated it and performed cloaking experiments in a thin-plate with a hole. Experiments were performed in a thin plate by using the lowest symmetric Lamb wave centered at 100 kHz. As a means to check the cloaking performance of the add-on elastic plate cloak, possibly as a temporary stress reliever or a so-called “stress bandage”, the degree of stress concentration mitigation and the recovery from the perturbed wave field due to a hole were investigated.

Suckling, Joanna K; Spradley, M Katherine; Godde, Kanya

2016-01-01

The development of a methodology that estimates the postmortem interval (PMI) from stages of decomposition is a goal for which forensic practitioners strive. A proposed equation (Megyesi et al. 2005) that utilizes total body score (TBS) and accumulated degree days (ADD) was tested using longitudinal data collected from human remains donated to the Forensic Anthropology Research Facility (FARF) at Texas State University-San Marcos. Exact binomial tests examined the rate of the equation to successfully predict ADD. Statistically significant differences were found between ADD estimated by the equation and the observed value for decomposition stage. Differences remained significant after carnivore scavenged donations were removed from analysis. Low success rates for the equation to predict ADD from TBS and the wide standard errors demonstrate the need to re-evaluate the use of this equation and methodology for PMI estimation in different environments; rather, multivariate methods and equations should be derived that are environmentally specific. © 2015 American Academy of Forensic Sciences.

Patient and public involvement (PPI) is central to research and service planning. Identifying effective, meaningful ways of involvement is challenging. The cohort study 'Do specialist services for teenagers and young adults with cancer add value?' follows young people for three years, examining outcomes associated with specialist care. Participant retention in longitudinal research can be problematic potentially jeopardising study completion. Maximising study awareness through high impact branding and publicity may improve study retention. Study names are typically generated by researchers rather than designed with patients. We aimed to involve young people in developing a brand identity and name to 'Do specialist services for teenagers and young adults with cancer add value?'. Nine young people aged 17-26 years diagnosed with cancer when aged 14-25 years participated in a one day workshop with further data collection at a patient conference. Methodology was similar to conventional branding and naming exercises and was divided into six stages. The workshop comprised five stages. Stage 1: 'What's in a brand' allowed young people to enquire why brands/logos are important, Stage 2: 'Brand Transformation' identified what young people needed to know and believe about the study when approached about participation, Stage 3: 'Brand Essence' determined how we wanted the study to be perceived by young people, Stage 4: 'What's in a name' identified potential names for the study. Stage 5: 'Logo creation' assembled the mood and feel of logos. Stage 6 was logo design and an electronic survey of 249 young people attending a patient conference. BRIGHTLIGHT was the final study name and the brand essence (or study personality) was friendly, supportive and inspiring. Four logos were designed and the final logo received 47% (n = 115) of votes. Acceptance and retention to BRIGHTLIGHT is higher than anticipated (80% versus 60%), this may be related to our integral PPI strategy. We propose this reproducible methodology as an important, enjoyable, and novel way of involving patients in research and a welcome alternative to researcher-developed acronyms. Ideally this should be carried out prior to engaging with healthcare professionals to prevent confusion around study identity.

The isolation of children with attention deficit disorder (ADD) among peers was examined by conducting sociometric tests in 28 classrooms to which ADD children belonged. The conclusions are as follows: 1. Among ADD children, 39.3% were classified as isolated children who received no Social Choice votes, a proportion that was significantly higher than normal controls. 2. Results suggests that isolation was correlated with such characteristics of ADD children as higher grade in school, later first consultation and lower IQ levels. 3. Classroom characteristics which correlated with isolation of ADD children were larger number of children per class and stronger class cohesion. It is thought that reducing the number of children in each class will be effective in preventing isolation of ADD children. 4. The possibility of an association between assessment of parents for social relationships of ADD children and their isolation exists and needs to be assessed. The authors emphasize the need for ADD children to have support in their interpersonal relationships, and discuss ways of intervention to prevent their being isolated in their classrooms.

The aim of this study was to evaluate the impact of two different therapeutic strategies in patients with partial seizures who were intractable to the first prescribed antiepileptic drug (AED); alternative monotherapy vs early add-on treatment. We conducted an open, cluster-randomised, prospective, controlled trial in patients with persistent partial seizures, despite treatment with one AED, who were never administered any other AEDs. Neurologists were randomised to two strategies: in group A, an alternative monotherapy with a second AED was employed; in group B, add-on treatment with a second AED was employed. The primary outcome was the percentage of seizure-free patients during a two-month period after six months of treatment. The secondary outcomes were: (i) the percentage of patients achieving a 50% reduction in the number of seizures at six months; (ii) the quality of life based on the Quality Of Life In Epilepsy scale; and (iii) tolerability. A total of 143 neurologists were included and randomised, and 264 patients were evaluated. At six months, the primary outcome was 51% in group A and 45% in group B (p=0.34). The percentage of patients achieving a 50% reduction in the number of seizures at six months was 76% in group A and 84% in group B (p=0.53). The quality of life and the tolerability did not significantly differ between the two groups. Alternative monotherapy or early treatment initiation with another AED drug resulted in similar efficacy, and the side effects associated with monotherapy and combined therapies were similar, which suggests that individual susceptibility is more important than the number and burden of AEDs used.

Attention-Deficit/Hyperactivity Disorder and Fatal Accidents in Aviation Medicine.

Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder with symptoms of inattention and/or hyperactivity-impulsivity that interfere with functioning and/or development. ADHD occurs in about 2.5% of adults. ADHD can be an excluding medical condition among pilots due to the risk of attentional degradation and therefore impact on flight safety. Diagnosis of ADHD is complex, which complicates aeromedical assessment. This study highlights fatal accident cases among pilots with ADHD and discusses protocols to detect its presence to help to assess its importance to flight safety. To identify fatal accidents in aviation (including airplanes, helicopters, balloons, and gliders) in the United States between the years 2000 to 2015, the National Transportation Safety Board (NTSB) database was searched with the terms ADHD, attention deficit hyperactivity disorder, and attention deficit disorder (ADD). The NTSB database search for fatal aviation accidents possibly associated with ADHD yielded four accident cases of interest in the United States [4/4894 (0.08%)]. Two of the pilots had ADHD diagnosed by a doctor, one was reported by a family member, and one by a flight instructor. An additional five cases were identified searching for ADD [5/4894 (0.1%)]. Altogether, combined ADHD and ADD cases yielded nine accident cases of interest (0.18%). It is generally accepted by aviation regulatory authorities that ADHD is a disqualifying neurological condition. Yet FAA and CASA provide specific protocols for tailor-made pilot assessment. Accurate evaluation of ADHD is essential because of its potential negative impact on aviation safety.Laukkala T, Bor R, Budowle B, Sajantila A, Navathe P, Sainio M, Vuorio A.

Illegal steroid administration to enhance growth performance in veal calves has long been, and still is, a serious issue facing regulatory agencies. Over the last years, stating undisputable markers of illegal treatment has become complex because of the endogenous origin of several anabolic steroids. Knowledge on the origin of an analyte is therefore of paramount importance. The present study shows the presence of steroid analytes in wooden crates used for housing veal calves. For this purpose, an analytical procedure using accelerated solvent extraction (ASE(R)), solid-phase extraction (SPE) and ultra-high performance liquid chromatography coupled to triple quadrupole mass spectrometry (U-HPLC-MS-MS) is developed for the characterisation of androstadienedione (ADD), boldenone (bBol), androstenedione (AED), beta-testosterone (bT), alpha-testosterone (aT), progesterone (P) and 17alpha-hydroxy-progesterone (OH-P) in wood samples. In samples of wooden crates used for housing veal calves, ADD, AED, aT and P could be identified. Using the standard addition approach concentrations of these analytes were determined ranging from 20 +/- 4 ppb to 32 +/- 4 ppb for ADD, from 19 +/- 5 ppb to 44 +/- 17 ppb for AED, from 11 +/- 6 ppb to 30 +/- 2 ppb for aT and from 14 +/- 1 ppb to 42 +/- 27 ppb for P, depending on the sample type. As exposure of veal calves to steroid hormones in their housing facilities might complicate decision-making on illegal hormone administration, inequitable slaughter of animals remains possible. Therefore, complete prohibition of wooden calf accommodation should be considered.

Episodic memory impairment is the core feature of typical Alzheimer's disease. To evaluate the performance of two commonly used verbal memory tests to detect mild cognitive impairment due to Alzheimer's disease (MCI-AD) and to predict progression to Alzheimer's disease dementia (AD-d). Prospective study of MCI patients in a tertiary memory disorder unit. Patients underwent an extensive neuropsychological battery including two tests of declarative verbal memory: The Free and Cued Selective Reminding Test (FCSRT) and the word list learning task from the Consortium to Establish a Registry for Alzheimer's disease (CERAD-WL). Cerebrospinal fluid (CSF) was obtained from all patients and MCI-AD was defined by means of the t-Tau/Aβ1-42 ratio. Logistic regression analyses tested whether the combination of FCSRT and CERAD-WL measures significantly improved the prediction of MCI-AD. Progression to AD-d was analyzed in a Cox regression model. A total of 202 MCI patients with a mean follow-up of 34.2±24.2 months were included and 98 (48.5%) met the criteria for MCI-AD. The combination of FCSRT and CERAD-WL measures improved MCI-AD classification accuracy based on CSF biomarkers. Both tests yielded similar global predictive values (59.9-65.3% and 59.4-62.8% for FCSRT and CERAD-WL, respectively). MCI-AD patients with deficits in both FCSRT and CERAD-WL had a faster progression to AD-d than patients with deficits in only one test. The combination of FCSRT and CERAD-WL improves the classification of MCI-AD and defines different prognostic profiles. These findings have important implications for clinical practice and the design of clinical trials.

Response inhibition in Attention deficit disorder and neurofibromatosis type 1 – clinically similar, neurophysiologically different

There are large overlaps in cognitive deficits occurring in attention deficit disorder (ADD) and neurodevelopmental disorders like neurofibromatosis type 1 (NF1). This overlap is mostly based on clinical measures and not on in-depth analyses of neuronal mechanisms. However, the consideration of such neuronal underpinnings is crucial when aiming to integrate measures that can lead to a better understanding of the underlying mechanisms. Inhibitory control deficits, for example, are a hallmark in ADD, but it is unclear how far there are similar deficits in NF1. We thus compared adolescent ADD and NF1 patients to healthy controls in a Go/Nogo task using behavioural and neurophysiological measures. Clinical measures of ADD-symptoms were not different between ADD and NF1. Only patients with ADD showed increased Nogo errors and reductions in components reflecting response inhibition (i.e. Nogo-P3). Early perceptual processes (P1) were changed in ADD and NF1. Clinically, patients with ADD and NF1 thus show strong similarities. This is not the case in regard to underlying cognitive control processes. This shows that in-depth analyses of neurophysiological processes are needed to determine whether the overlap between ADD and NF1 is as strong as assumed and to develop appropriate treatment strategies.

The safety of triple oral therapy with dapagliflozin plus saxagliptin plus metformin versus dual therapy with dapagliflozin or saxagliptin plus metformin was compared in a post-hoc analysis of 3 randomized trials of sequential or concomitant add-on of dapagliflozin and saxagliptin to metformin. In the concomitant add-on trial, patients with type 2 diabetes on stable metformin received dapagliflozin 10 mg/d plus saxagliptin 5 mg/d. In sequential add-on trials, patients on metformin plus either saxagliptin 5 mg/d or dapagliflozin 10 mg/d received dapagliflozin 10 mg/d or saxagliptin 5 mg/d, respectively, as add-on therapy. After 24 weeks, incidences of adverse events and serious adverse events were similar between triple and dual therapy and between concomitant and sequential add-on regimens. Urinary tract infections were more common with sequential than with concomitant add-on therapy; genital infections were reported only with sequential add-on of dapagliflozin to saxagliptin plus metformin. Hypoglycaemia incidence was <2.0% across all analysis groups. In conclusion, the safety and tolerability of triple therapy with dapagliflozin, saxagliptin and metformin, as either concomitant or sequential add-on, were similar to dual therapy with either agent added to metformin. © 2018 The Authors.

Although the cognitive impairment in Alzheimer's disease (AD) is believed to be caused by amyloid-β (Aβ) plaques and neurofibrillary tangles (NFTs), several postmortem studies have reported cognitive normal subjects with AD brain pathology. As the mechanism underlying these discrepancies has not been clarified, we focused the neuroprotective role of astrocytes. After examining 47 donated brains, we classified brains into 3 groups, no AD pathology with no dementia (N-N), AD pathology with no dementia (AD-N), and AD pathology with dementia (AD-D), which represented 41%, 21%, and 38% of brains, respectively. No differences were found in the accumulation of Aβ plaques or NFTs in the entorhinal cortex (EC) between AD-N and AD-D. Number of neurons and synaptic density were increased in AD-N compared to those in AD-D. The astrocytes in AD-N possessed longer or thicker processes, while those in AD-D possessed shorter or thinner processes in layer I/II of the EC. Astrocytes in all layers of the EC in AD-N showed enhanced GLT-1 expression in comparison to those in AD-D. Therefore these activated forms of astrocytes with increased GLT-1 expression may exert beneficial roles in preserving cognitive function, even in the presence of Aβ and NFTs.

In this paper, we report our experimental study on directly coupling a micro/nano fiber (MNOF) ring with a side-polished fiber(SPF). As a result of the study, the behavior of an add-drop filter was observed. The demonstrated add-drop filter explored the wavelength dependence of light coupling between a MNOF ring and a SPF. The characteristics of the filter and its performance dependence on the MNOF ring diameter were investigated experimentally. The investigation resulted in an empirically obtained ring diameter that showed relatively good filter performance. Since light coupling between a (MNOF) and a conventional single mode fiber has remained a challenge in the photonic integration community, the present study may provide an alternative way to couple light between a MNOF device and a conventional single mode fiber based device or system. The hybridization approach that uses a SPF as a platform to integrate a MNOF device may enable the realization of other all-fiber optical hybrid devices.

Parkinson's disease (PD) is the second most common neurological disease affecting older adults. Consequently, this disease should be a focus among payers, with increasing utilization of newer premium-priced patent-protected add-on therapies to stabilize or even improve motor function over time. However, expenditure can be moderated by reforms. Consequently, there is a need to assess the influence of these reforms on the prescribing efficiency for drugs to treat PD in Croatia before proposing additional measures. Prescribing efficiency is defined as increasing the use of add-on therapies for similar expenditure. An observational retrospective study of the Croatian Institute for Health Insurance database of drugs to treat patients with PD in Croatia from 2000 to 2010 was carried out, with utilization measured in defined daily doses (defined as the average maintenance dose of a drug when used in its major indication in adults). The study years were chosen to reflect recent reforms. Only reimbursed expenditure is measured from a health insurance perspective. Utilization of drugs to treat PD increased by 218% between 2000 and 2010. Reimbursed expenditure increased by 360%, principally driven by increasing utilization of premium-priced patent-protected add-on therapies, including ropinirole and pramipexole. However, following recent reforms, reducing expenditure/defined daily dose for the different drugs, as well as overall expenditure, stabilized reimbursed expenditure between 2005 and 2010. Treatment of PD is complex, and add-on therapies are needed to improve care. Reimbursed expenditure should now fall following stabilization, despite increasing volumes, as successive add-on therapies lose their patents, further increasing prescribing efficiency.

Background/Aims To analyze the effects of preexisting lamivudine (LAM) resistance and applying antiviral treatment (adefovir [ADV] add-on LAM combination treatment) on long-term treatment outcomes, and comparing the clinical outcomes of antiviral-naïve chronic hepatitis B patients receiving entecavir (ETV) monotherapy. Methods This study enrolled 73 antiviral-naïve patients who received 0.5-mg ETV as an initial therapy and 54 patients who received ADV add-on LAM combination treatment as a rescue therapy from July 2006 to July 2010. Results During 24-month treatments, the decreases in serum log10HBV-DNA values (copies/mL) were significantly greater in the antiviral-naïve patients treated with ETV than the patients receiving ADV add-on LAM combination treatment. The biochemical response rates for alanine aminotransferase normalization at 6 months (ETV) and 12 months (ADV add-on LAM) were 90.4% (66/73) and 77.8% (42/54), respectively (P=0.048). A Kaplan-Meier analysis indicated that the rates of serologic response, viral breakthrough, and emergence of genotypic resistance did not differ significantly between the two patient groups. There were also no significant intergroup differences in the rates of disease progression (PD) and new development of hepatocellular carcinoma (HCC). Conclusion The long-term clinical outcomes of antiviral-naïve patients treated with ETV and LAM-resistant patients receiving ADV add-on LAM combination treatment were comparable in terms of the emergence of HCC and disease progression.

3-ketosteroid-Δ 1 -dehydrogenase (KSDD), a flavin adenine dinucleotide (FAD)-dependent enzyme involved in sterol metabolism, specifically catalyses the conversion of androst-4-ene-3,17-dione (AD) to androst-1,4-diene-3,17-dione (ADD). However, the low KSDD activity and the toxic effects of hydrogen peroxide (H 2 O 2 ) generated during the biotransformation of AD to ADD with FAD regeneration hinder its application on AD conversion. The aim of this work was to improve KSDD activity and eliminate the toxic effects of the generated H 2 O 2 to enhance ADD production. The ksdd gene obtained from Mycobacterium neoaurum JC-12 was codon-optimized to increase its expression level in Bacillus subtilis, and the KSDD activity reached 12·3 U mg -1 , which was sevenfold of that of codon-unoptimized gene. To improve AD conversion, catalase was co-expressed with KSDD in B. subtilis 168/pMA5-ksdd opt -katA to eliminate the toxic effects of H 2 O 2 generated during AD conversion. Finally, under optimized bioconversion conditions, fed-batch strategy was carried out and the ADD yield improved to 8·76 g l -1 . This work demonstrates the potential to improve enzyme activity by codon-optimization and eliminate the toxic effects of H 2 O 2 by co-expressing catalase. This study showed the highest ADD productivity ever reported and provides a promising strain for efficient ADD production in the pharmaceutical industry. © 2016 The Society for Applied Microbiology.

The objective of this study was to evaluate the effect of atorvastatin add-on therapy on cerebral atrophy in relapsing-remitting multiple sclerosis. This randomised, placebo-controlled study compared atorvastatin 40 mg or placebo add-on therapy to interferon β1b for 24 months. Brain magnetic resonance imaging, multiple sclerosis functional composite score, Rao neuropsychological battery and expanded disability status scale were evaluated over 24 months. A total of 154 patients were randomly assigned, 75 in the atorvastatin and 79 in the placebo arms, with a comparable drop-out rate (overall 23.4%). Brain atrophy over 2 years was not different in the two arms (-0.38% and -0.32% for the atorvastatin and placebo groups, respectively). Relapse rate, expanded disability status scale, multiple sclerosis functional composite score or cognitive changes were not different in the two arms. Patients withdrawing from the study had a higher number of relapses in the previous 2 years (P=0.04) and a greater probability of relapsing within 12 months. Our results suggest that the combination of atorvastatin and interferon β1b is not justified in early relapsing-remitting multiple sclerosis and adds to the body of evidence indicating an absence of significant radiological and clinical benefit of statins in relapsing-remitting multiple sclerosis. © The Author(s), 2015.

The goal of our study was to compare the incidence of Attention Deficit Hyperactivity Disorder (ADHD) observed in students at the School of Physical Education and Sports (SPES), which is a school that provides higher education in athletics, with that observed in students studying in other departments of the university. Our hypothesis was that people with ADHD most commonly turn to sports. The study enrolled 318 (75.7% of 420) students who were studying in the SPES of Gaziantep University; 277 students from the medical, nursing, administration, and engineering faculties were enrolled to serve as a control group. All students enrolled in the study were informed about the study before the lesson, and the students who agreed to participate provided written consent. Scales used in this study were: a sociodemographic information form which was prepared by the investigators, the Wender-Utah Rating Scale (WURS), and the Adult ADD/ADHD DSM-IV Based Diagnostic Screening and Rating Scale (ADD/ADHD). WURS scores were significantly higher (25.07 +/- 15.15 versus 21.37 +/- 14.28; p = 0.002) in the SPES group than the control group. In addition, the percentage of subjects with a WURS score above the cut-off of 36 was higher in the SPES group than the control group (22.4% versus 15.2%; p: 0.028). The two groups were not significantly different in terms of the subscales of the ADD/ADHD scale. A correlation was found between the educational achievement of the students in the SPES group and the ADD/ADHD-inattention subscale (r = .111, p = 0.015) and WURS scale (r = .113, p = 0.011). More systematic studies with larger samples in this domain will be useful in obtaining a clearer picture regarding professional attraction of people with ADHD to sports.

Just add a pinch of salt!--current directions for the use of salt in recipes in Australian magazines.

Australians currently consume too much salt causing adverse consequences for health. The media play an important role in the provision of nutrition advice to consumers. Previous research shows that many foods advertized in consumer magazines are high in salt, but little research has examined magazine recipes in this context. The aim of this project was to summarize directions for salt use in recipes in leading Australian magazines. In August 2007 and 2008, the top 10 magazines by circulation that included at least five recipes, were examined. Standardized information was collected about directions for salt use in recipes. Three hundred and thirty recipes were identified in 2007 and 417 in 2008. About 68% of recipes included high-salt ingredients, 37% instructed to season with salt, 10% instructed to add a specific quantity of salt and 15% recommended selection of low-salt ingredients. There was substantial variability in directions for salt use in recipes between magazines, but no clear differences between 2007 and 2008. Many recipes advised to add salt in direct contradiction to national dietary guidelines. There is clear potential for editorial guidelines on salt use in recipes to play a role in advancing public health efforts in Australia and other such nations.

The interplay of health claims and taste importance on food consumption and self-reported satiety.

PubMed

Vadiveloo, Maya; Morwitz, Vicki; Chandon, Pierre

2013-12-01

Research has shown that subtle health claims used by food marketers influence pre-intake expectations, but no study has examined how they influence individuals' post-consumption experience of satiety after a complete meal and how this varies according to the value placed on food taste. In two experiments, we assess how labeling a pasta salad as "healthy" or "hearty" influences self-reported satiety, consumption volume, and subsequent consumption of another food. Using MANOVA, Study 1 shows that individuals who report low taste importance consume less-yet feel just as satiated-when a salad is labeled "hearty" rather than "healthy." In contrast, for individuals with higher taste importance, consumption and self-reported satiety are correlated and are both higher when a salad is labeled as "hearty" versus "healthy." Study 2 primes taste importance, rather than measuring it, and replicates these findings for consumption, but not for self-reported satiety. There was no effect on the consumption of other foods in either study. Overall, our findings add to earlier work on the impact of health labels by showing that subtle food descriptions also influence post-intake experiences of satiety, but that the direction of the effects depends on taste importance and on the selection of direct or indirect measures of satiety.

2017-04-01

Epithelium is an important and highly specialised tissue type that makes up the lining of inner and outer surfaces of the human body. It is proposed that a self-study tool adds to efficient learning and lecturing on this complicated topic in medical curricula. This paper describes the development and evaluation of an online interactive 3D resource on epithelium for undergraduate medical students. A first evaluation was carried out by means of an online survey (n = 37). The resource was evaluated positively on the website in general, its visual contents and its value and potential for the medical curriculum.

An experience of studying abroad or of academic exchange, really adds value to the professional and personal development of exchange students. This report aims to describe a student's experience in an international academic mobility program. It was developed from 2008 to 2009 in Brazil and Spain. The experiences, observations and activities of the student were emphasized believing that the training of students and researchers is not only restricted to the university and the students' home country, and that it is important to have possibilities of new experiences and differentiated knowledge. The conclusion is that this opportunity promoted a profound effect on psychological, cultural social and scientific development of the exchange student.

The shifting sands of self: a framework for the experience of self in addiction.

PubMed

Gray, Mary Tod

2005-04-01

The self is a common yet unclear theme in addiction studies. William James's model of self provides a framework to explore the experience of self. His model details the subjective and objective constituents, the sense of self-continuity through time, and the ephemeral and plural nature of the changing self. This exploration yields insights into the self that can be usefully applied to subjective experiences with psychoactive drugs of addiction. Results of this application add depth to the common understanding of self in addiction, acknowledge the importance of feelings and choice in the sense of self created in addiction experiences, and affirm the values salient to these interior experiences in addiction. These results suggest meaning derived from those values, and provide important background knowledge for the nurse interacting with these clients.

International Monetary Fund and aid displacement.

PubMed

Stuckler, David; Basu, Sanjay; McKee, Martin

2011-01-01

Several recent papers find evidence that global health aid is being diverted to reserves, education, military, or other sectors, and is displacing government spending. This is suggested to occur because ministers of finance have competing, possibly corrupt, priorities and deprive the health sector of resources. Studies have found that development assistance for health routed to governments has a negative impact on health spending and that similar assistance routed to private nongovernmental organizations has a positive impact. An alternative hypothesis is that World Bank and IMF macro-economic policies, which specifically advise governments to divert aid to reserves to cope with aid volatility and keep government spending low, could be causing the displacement of health aid. This article evaluates whether aid displacement was greater when countries undertook a new borrowing program from the IMF between 1996 and 2006. As found in existing studies, for each $1 of development assistance for health, about $0.37 is added to the health system. However, evaluating IMF-borrowing versus non-IMF-borrowing countries reveals that non-borrowers add about $0.45 whereas borrowers add less than $0.01 to the health system. On average, health system spending grew at about half the speed when countries were exposed to the IMF than when they were not. It is important to take account of the political economy of global health finance when interpreting data on financial flows.

To examine race and ethnic differences in the importance of obesity for social integration using the National Longitudinal Study of Adolescent Health (Add Health). A cross-sectional study utilizing survey-adjusted statistics and multivariate logistic and linear regression models. Models were stratified by sex and included interaction terms capturing race, ethnicity and obesity. United States of America. A nationally representative sample of 15,355 respondents grades 7 through 12 who participated in both the In-School and In-Home Wave I surveys of Add Health. Four self-reported and schoolmate-reported indicators of social integration. The consequences of obesity for social integration are greatest for White adolescents, who were selected by almost 2 fewer schoolmates as friends and had half the odds of having their friendships reciprocated compared with non-obese White adolescents. The social disadvantage of obesity was lower for non-White adolescents; though they are selected by significantly fewer schoolmates as friends and were less likely to have their friendships reciprocated, they did not face additional discrimination from being both obese and minority. There are significant differences between obese and non-obese adolescents by race and ethnicity in friendships. As friendships are among the most valued assets in adolescence, understanding the impact of obesity on access to friendships for diverse adolescents is a necessary component to understanding the complex motivations that guide health-related behavior at these formative ages.

Phase-field modeling of two-dimensional crystal growth with anisotropic diffusion.

PubMed

Meca, Esteban; Shenoy, Vivek B; Lowengrub, John

2013-11-01

In the present article, we introduce a phase-field model for thin-film growth with anisotropic step energy, attachment kinetics, and diffusion, with second-order (thin-interface) corrections. We are mainly interested in the limit in which kinetic anisotropy dominates, and hence we study how the expected shape of a crystallite, which in the long-time limit is the kinetic Wulff shape, is modified by anisotropic diffusion. We present results that prove that anisotropic diffusion plays an important, counterintuitive role in the evolving crystal shape, and we add second-order corrections to the model that provide a significant increase in accuracy for small supersaturations. We also study the effect of different crystal symmetries and discuss the influence of the deposition rate.

Religion and Early Marriage in the United States: Evidence from the Add Health Study

PubMed Central

Uecker, Jeremy

2014-01-01

Early marriage has important consequences for individuals in the United States. Several studies have linked religion to early marriage but have not examined this relationship in depth. Using data from Waves 1, 3, and 4 of the National Longitudinal Study of Adolescent Health, I conduct multilevel event-history analysis to examine how religion, at both individual and contextual levels, is associated with early marriage. Further, I test mediators of the religion-early marriage relationship. I find significant variation in early marriage by religious tradition, religious service attendance, religious salience, belief in scriptural inerrancy, and religious context in high school. The individual religious effects—but not the school context effects—are explained in part by differential attitudes toward marriage and cohabitation. PMID:25045173

2016-03-01

Depression is prevalent in adults with congenital heart disease (ACHD), but limited data on the frequency of anti-depressant drug (ADD) therapy and its impact on outcome are available. We identified all ACHD patients treated with ADDs between 2000 and 2011 at our centre. Of 6162 patients under follow-up, 204 (3.3%) patients were on ADD therapy. The majority of patients were treated with selective serotonin-reuptake inhibitors (67.4%), while only 17.0% of patients received tricyclic anti-depressants. Twice as many female patients used ADDs compared with males (4.4 vs. 2.2%, P < 0.0001). The percentage of patients on ADDs increased with disease complexity (P < 0.0001) and patient age (P < 0.0001). Over a median follow-up of 11.1 years, 507 (8.2%) patients died. After propensity score matching, ADD use was found to be significantly associated with worse outcome in male ACHD patients [hazard ratio 1.44 (95% confidence interval 1.17-1.84)]. There was no evidence that this excess mortality was directly related to ADD therapy, QT-prolongation, or malignant arrhythmias. However, males taking ADDs were also more likely to miss scheduled follow-up appointments compared with untreated counterparts, while no such difference in clinic attendance was seen in females. The use of ADD therapy in ACHD relates to gender, age, and disease complexity. Although, twice as many female patients were on ADDs, it were their male counterparts, who were at increased mortality risk on therapy. Furthermore, males on ADDs had worse adherence to scheduled appointments suggesting the need for special medical attention and possibly psychosocial intervention for this group of patients.

Dissecting Alzheimer disease in Down syndrome using mouse models

PubMed Central

Choong, Xun Yu; Tosh, Justin L.; Pulford, Laura J.; Fisher, Elizabeth M. C.

2015-01-01

Down syndrome (DS) is a common genetic condition caused by the presence of three copies of chromosome 21 (trisomy 21). This greatly increases the risk of Alzheimer disease (AD), but although virtually all people with DS have AD neuropathology by 40 years of age, not all develop dementia. To dissect the genetic contribution of trisomy 21 to DS phenotypes including those relevant to AD, a range of DS mouse models has been generated which are trisomic for chromosome segments syntenic to human chromosome 21. Here, we consider key characteristics of human AD in DS (AD-DS), and our current state of knowledge on related phenotypes in AD and DS mouse models. We go on to review important features needed in future models of AD-DS, to understand this type of dementia and so highlight pathogenic mechanisms relevant to all populations at risk of AD.

Approach to the unfolding and folding dynamics of add A-riboswitch upon adenine dissociation using a coarse-grained elastic network model

Riboswitches are noncoding mRNA segments that can regulate the gene expression via altering their structures in response to specific metabolite binding. We proposed a coarse-grained Gaussian network model (GNM) to examine the unfolding and folding dynamics of adenosine deaminase (add) A-riboswitch upon the adenine dissociation, in which the RNA is modeled by a nucleotide chain with interaction networks formed by connecting adjoining atomic contacts. It was shown that the adenine binding is critical to the folding of the add A-riboswitch while the removal of the ligand can result in drastic increase of the thermodynamic fluctuations especially in the junction regions between helix domains. Under the assumption that the native contacts with the highest thermodynamic fluctuations break first, the iterative GNM simulations showed that the unfolding process of the adenine-free add A-riboswitch starts with the denature of the terminal helix stem, followed by the loops and junctions involving ligand binding pocket, and then the central helix domains. Despite the simplified coarse-grained modeling, the unfolding dynamics and pathways are shown in close agreement with the results from atomic-level MD simulations and the NMR and single-molecule force spectroscopy experiments. Overall, the study demonstrates a new avenue to investigate the binding and folding dynamics of add A-riboswitch molecule which can be readily extended for other RNA molecules.

The Hidden Complexity of Biological "Dirty Bombs": Implications for Special Operations Medical Personnel.

Washington, Michael A; Blythe, Jauchia

The recent capture of a terrorist in Belgium carrying explosives, fecal matter, and animal tissue may indicate a shift from conventional weapons to crude bacteriological preparations as instruments of terror. It is important to note that although such weapons lack technological sophistication, bacteria are inherently complex, unpredictable, and undetectable in the field. Therefore, it is important that Special Operations medical personnel understand the complications that such seemingly simple devices can add to the treatment of casualties in the field and subsequent evaluation in the clinic. 2016.

Although informatics is an important area of nursing inquiry and practice, few scholars have articulated the philosophical foundations of the field or how these translate into practice including the often-cited data, information, knowledge, and wisdom (DIKW) framework. Data, information, and knowledge, often approached through postpositivism, can be exhibited in computer systems. Wisdom aligns with constructivist epistemological perspectives such as Gadamerian hermeneutics. Computer systems can support wisdom development. Wisdom is an important element of the DIKW framework and adds value to the role of nursing informaticists and nursing science.

It is necessary to evaluate cyclists' exposure to particulate matter and if they are at a higher risk due to their increased breathing rate and their exposure to freshly emitted pollutants. The aim of this pilot study was to determine cyclists' exposure to PM 10 in a highly-polluted, high-altitude city such as Bogotá, and comment on the appropriateness of building bicycle paths alongside roads with heavy traffic in third world cities. A total of 29 particulate matter (PM 10) measurements, taken at two sampling sites using Harvard impactors, were used for estimating the exposure of users of the 80th street bicycle path to this pollutant. PM 10 dose could be considered as being high, especially due to high concentrations and cyclists' increased inhalation rates. A random survey was conducted over 73 bicycle path users to determine cyclists' time, distance and speed on the bicycle path on a daily and weekly basis, their level of effort when cycling and general characteristics, such as this population's gender and age. Based on this information, the PM 10 average daily dose (ADD c) for different bicycle path users and the ratio between ADD c and a reference ADD for people at rest exposed to an indoor concentration of 25 μg m -3 were estimated. The average increase in ADD was 6%-9% when riding with light effort and by 12%-18% when riding with moderate effort. The most enthusiastic bicycle path users showed ADD c/ADD r ratios as high as 1.30 when riding with light effort and 1.64 when riding with moderate effort, thereby significantly increasing their PM 10 exposure-associated health risks.

To evaluate the efficacy and safety profile of carbomer-based lipid-containing artificial tear formulations (CBLAT) in patients with dry eye syndrome. A multicenter parallel-group study was conducted in 412 patients with dry eye syndrome. Of these patients, 221 switched from using artificial tears to CBLAT (switching group) and 191 added CBLAT to their current treatment (add-on group). Ocular symptom scores, ocular staining grades, tear film breakup time (tBUT), Schirmer I test value, and Korean dry eye level (as defined by the Korean Corneal Disease Study Group guidelines) were evaluated at baseline and after 4 weeks of treatment. After 4 weeks of treatment, ocular surface staining grade, tBUT, Schirmer I value, ocular irritation symptom scores, and the positive rate of visual symptom improved significantly in both groups. Mean reductions in ocular surface staining grades (-0.8 ± 0.9) and ocular irritation symptom scores (-0.8 ± 0.8) in the add-on group were significantly higher than those (-0.5 ± 0.8 and -0.6 ± 0.8) in the switching group (P < 0.01 and P < 0.05). The positive rate of visual symptoms (44.2%) in the add-on group was significantly higher than that (26.4%) in the switching group (P < 0.01). The decrease of Korean dry eye level was 30.1% in the switching group and 51.6% in the add-on group. More patients in the add-on group had decreased dry eye levels than those in the switching group (P < 0.0001). CBLAT improves ocular surface staining grades, tBUT, Schirmer I values, and ocular symptoms in patients with dry eye syndrome.

Demographic history and gene flow during silkworm domestication

PubMed Central

2014-01-01

Background Gene flow plays an important role in domestication history of domesticated species. However, little is known about the demographic history of domesticated silkworm involving gene flow with its wild relative. Results In this study, four model-based evolutionary scenarios to describe the demographic history of B. mori were hypothesized. Using Approximate Bayesian Computation method and DNA sequence data from 29 nuclear loci, we found that the gene flow at bottleneck model is the most likely scenario for silkworm domestication. The starting time of silkworm domestication was estimated to be approximate 7,500 years ago; the time of domestication termination was 3,984 years ago. Using coalescent simulation analysis, we also found that bi-directional gene flow occurred during silkworm domestication. Conclusions Estimates of silkworm domestication time are nearly consistent with the archeological evidence and our previous results. Importantly, we found that the bi-directional gene flow might occur during silkworm domestication. Our findings add a dimension to highlight the important role of gene flow in domestication of crops and animals. PMID:25123546

Epilepsy is a common neurological disorder, affecting almost 0.5 to 1% of the population. Nearly 30% of patients with epilepsy are refractory to currently available drugs. Lamotrigine is one of the newer antiepileptic drugs and is the topic of this review. To examine the effects of lamotrigine on seizures, side effects, cognition and quality of life, when used as an add-on treatment for patients with drug-resistant partial epilepsy. We searched the Cochrane Epilepsy Group trials register, the Cochrane Controlled Trials Register (Cochrane Library Issue 2, 2001), MEDLINE (January 1966 to April 2001) and reference lists of articles. We also contacted the manufacturers of lamotrigine (Glaxo-Wellcome). Randomized placebo controlled trials, of patients with drug-resistant partial epilepsy of any age, in which an adequate method of concealment of randomization was used. The studies may be double, single or unblinded. For crossover studies, the first treatment period was treated as a parallel trial. Two reviewers independently assessed the trials for inclusion and extracted data. Primary analyses were by intention to treat. Outcomes included 50% or greater reduction in seizure frequency, treatment withdrawal (any reason), side effects, effects on cognition, and quality of life. We found three parallel add-on studies and eight cross-over studies, which included 1243 patients (199 children and 1044 adults). The overall Peto's Odds Ratio (OR) and 95% confidence intervals (CIs) across all studies for 50% or greater reduction in seizure frequency was 2.71 (1.87, 3.91) indicating that lamotrigine is significantly more effective than placebo in reducing seizure frequency. The overall OR (95%CI) for treatment withdrawal (for any reason) is 1.12 (0.78, 1.61). The 99% CIs for ataxia, dizziness, nausea, and diplopia do not include unity, indicating that they are significantly associated with lamotrigine. The limited data available precludes any conclusions about effects on cognition and quality of life, though there may be minor benefits in affect balance (happiness) and mastery. Lamotrigine add-on therapy is effective in reducing the seizure frequency, in patients with drug-resistant partial epilepsy. Further trials are needed to assess the long term effects of lamotrigine, and to compare it with other add-on drugs.

A study was undertaken that explored several aspects of technical communications in aeronautics. The study, which utilized survey research in the form of a self-administered questionnaire, was sent to 2,000 randomly selected members of the American Institute of Aeronautics and Astronautics. Six hundred and six usable questionnaires (30.3 percent) were received by the established cut off date. The study had five objectives. The first was to solicit the opinions of aeronautical engineers and scientists regarding the importance of technical communications to their profession; second, to determine their use and production of technical communications; third, to seek their views on the content of an undergraduate course in technical communications; fourth, to determine their use of libraries/technical information centers; and finally, to determine the use and importance of computer and information technology to them. The findings add considerable information to the knowledge of technical communications practices among aeronautical engineers and scientists and reinforce some of the conventional wisdom about technical communications and question other widely-held notions.

Understanding the Etiology of Prescription Opioid Abuse: Implications for Prevention and Treatment

Although studies on the initiation of substance abuse abound, the body of literature on prescription opioid abuse (POA) etiology is small. Little is known about why and how the onset of POA occurs, especially among high-risk populations. In this study we aimed to fill this important knowledge gap by exploring the POA initiation experiences of 90 prescription opioid abusers currently in treatment and their narrative accounts of the circumstances surrounding their POA onset. This research was conducted within a storyline framework, which operates on the premise that the path to drug abuse represents a biography or a process rather than a static condition. Audiotapes of in-depth interviews were transcribed, coded, and thematically analyzed. Analyses revealed the presence of four trajectories leading to POA. This study adds to the limited research on POA etiology by not only illuminating the psychosocial factors that contribute to POA onset, but also by situating initiation experiences within broader life processes. The study findings provide crucial insights to policymakers and interventionists in identifying who is at risk for POA, and more important, when and how to intervene most efficaciously.

Genetic background effects in quantitative genetics: gene-by-system interactions.

PubMed

Sardi, Maria; Gasch, Audrey P

2018-04-11

Proper cell function depends on networks of proteins that interact physically and functionally to carry out physiological processes. Thus, it seems logical that the impact of sequence variation in one protein could be significantly influenced by genetic variants at other loci in a genome. Nonetheless, the importance of such genetic interactions, known as epistasis, in explaining phenotypic variation remains a matter of debate in genetics. Recent work from our lab revealed that genes implicated from an association study of toxin tolerance in Saccharomyces cerevisiae show extensive interactions with the genetic background: most implicated genes, regardless of allele, are important for toxin tolerance in only one of two tested strains. The prevalence of background effects in our study adds to other reports of widespread genetic-background interactions in model organisms. We suggest that these effects represent many-way interactions with myriad features of the cellular system that vary across classes of individuals. Such gene-by-system interactions may influence diverse traits and require new modeling approaches to accurately represent genotype-phenotype relationships across individuals.

Clinical nursing informatics. Developing tools for knowledge workers.

Ozbolt, J G; Graves, J R

1993-06-01

Current research in clinical nursing informatics is proceeding along three important dimensions: (1) identifying and defining nursing's language and structuring its data; (2) understanding clinical judgment and how computer-based systems can facilitate and not replace it; and (3) discovering how well-designed systems can transform nursing practice. A number of efforts are underway to find and use language that accurately represents nursing and that can be incorporated into computer-based information systems. These efforts add to understanding nursing problems, interventions, and outcomes, and provide the elements for databases from which nursing's costs and effectiveness can be studied. Research on clinical judgment focuses on how nurses (perhaps with different levels of expertise) assess patient needs, set goals, and plan and deliver care, as well as how computer-based systems can be developed to aid these cognitive processes. Finally, investigators are studying not only how computers can help nurses with the mechanics and logistics of processing information but also and more importantly how access to informatics tools changes nursing care.

Visual risk factors for falls in older people.

PubMed

Lord, Stephen R

2006-09-01

Poor vision reduces postural stability and significantly increases the risk of falls and fractures in older people. Most studies have found that poor visual acuity increases the risk of falls. However, studies that have included multiple visual measures have found that reduced contrast sensitivity and depth perception are the most important visual risk factors for falls. Multifocal glasses may add to this risk because their near-vision lenses impair distance contrast sensitivity and depth perception in the lower visual field. This reduces the ability of an older person to detect environmental hazards. There is now evidence that maximising vision through cataract surgery is an effective strategy for preventing falls. Further randomised controlled trials are required to determine whether individual strategies (such as restriction of use of multifocal glasses) or multi-strategy visual improvement interventions can significantly reduce falls in older people. Public health initiatives are required to raise awareness in older people and their carers of the importance of regular eye examinations and use of appropriate prescription glasses.

A worthy self is a caring self: Examining the developmental relations between self-esteem and self-compassion in adolescents.

PubMed

2017-08-18

Self-compassion has been framed as a healthy alternative to self-esteem, as it is nonevaluative. However, rather than being alternatives, it may be that the two constructs develop in a mutually reinforcing way. The present study tested this possibility among adolescents. A large adolescent sample (N = 2,809; 49.8% female) reported levels of trait self-esteem and self-compassion annually for 4 years. Autoregressive cross-lagged structural equation models were used to estimate the reciprocal longitudinal relations between the two constructs. Self-esteem consistently predicted changes in self-compassion across the 4 years of the study, but not vice versa. Self-esteem appears to be an important antecedent of the development of self-compassion, perhaps because the capacity to extend compassion toward the self depends on one's appraisals of worthiness. These findings add important insights to our theoretical understanding of the development of self-compassion. © 2017 Wiley Periodicals, Inc.

2018-06-01

The application of homeopathic treatment quickly becomes a matter of ideological confrontation; however, homeopathy is steadily gaining in sympathy in the population. Although the possible effectiveness and the modes of action are currently not scientifically elucidated and the study situation regarding homeopathic treatment in psychiatry is still manageable, there is a whole series of positive evidence for the effects of homeopathic remedies for mental disorders, such as depression, anxiety disorders and addiction. The most important studies are presented and the most important arguments are weighed up with respect to the pros and cons. It is clear that homoeopathic remedies can only be used as an add-on and not alone. These remedies belong in the hands of physicians experienced in homeopathic and psychiatric psychopharmacology. It would be advisable to at least try out homeopathy for the well-being of the patient not only in the case of very mild disorders but also in severe chronic cases, since due to the generally good tolerability, no avoidable disadvantage should result.

Literature as an exploration of the phenomenology of schizophrenia: disorder and recovery in Denis Johnson's Jesus' Son.

PubMed

Hamm, Jay A; Leonhardt, Bethany L; Fogley, Rebecca L; Lysaker, Paul H

2014-12-01

When read as a fictional psychosis narrative, Jesus' Son, a collection of short stories by Denis Johnson, reveals important elements of the phenomenology of schizophrenia and recovery. It is possible that Jesus' Son, as a work of fiction, may be able to uniquely add depth and nuance to an understanding of the phenomenology of schizophrenia involving a state of psychological fragmentation, an ever-changing interpersonal field and a loss of personal agency. In addition, by following the protagonist in Jesus' Son as he begins to resolve some of his difficulties, the book also offers an individualised account of recovery. The authors detail how the book reveals these insights about schizophrenia and recovery and suggest that these elements are intertwined in such a manner that leads to a profound disruption of self-experience, characterised by a collapse of metacognitive processes. Jesus' Son may add depth to our understanding of the subjective experience of schizophrenia and recovery, and also may serve as one example in which the study of humanities offers an opportunity to explore the human elements in the most profound forms of suffering.

Food fortification is an interesting strategy to treat and prevent iron anemia. This study aims to quantify the iron in yoghurt, with gelatin and sugar and without, prepared in iron and glass containers. Sensorial test was use to evaluate the acceptance and preference of the both products. The yoghurt was prepared in containers of iron and glass with UHT milk, powder milk and natural industrialized yoghurt. After fermentation, half of the product received addition of sugar and strawberry flavor gelatin. The collected samples get the total iron quantified by ICP OES. Sensorial analysis involving 105 consumers was use to determine the acceptance and preference of the products. 0,018 and 0,882mg of iron per 100g added in the natural yoghurt prepared in the glass and in the iron pots, respectively. The yoghurt with gelatin presented 0,037 and 1,302mg of iron per 100g when prepared in the glass and in the iron pots, respectively. The preference was low for the yoghurt prepared in the iron pot (29,5%), but when added strawberry gelatin it was about 51,5%. The yoghurt prepared in iron pots, is easily home made and adds important amount of iron. Add gelatin and sugar can favored its consumption.

In this paper, we report our experimental study on directly coupling a micro/nano fiber (MNOF) ring with a side-polished fiber(SPF). As a result of the study, the behavior of an add-drop filter was observed. The demonstrated add-drop filter explored the wavelength dependence of light coupling between a MNOF ring and a SPF. The characteristics of the filter and its performance dependence on the MNOF ring diameter were investigated experimentally. The investigation resulted in an empirically obtained ring diameter that showed relatively good filter performance. Since light coupling between a (MNOF) and a conventional single mode fiber has remained a challenge in the photonic integration community, the present study may provide an alternative way to couple light between a MNOF device and a conventional single mode fiber based device or system. The hybridization approach that uses a SPF as a platform to integrate a MNOF device may enable the realization of other all-fiber optical hybrid devices. PMID:25578467

Debnam, Katrina J; Johnson, Sarah L; Bradshaw, Catherine P

2014-07-01

The school environment is an important context for understanding risk factors for teen dating violence. This study seeks to add to the growing literature base linking adolescent experiences with bullying and involvement with teen dating violence. Data were collected from 27,074 adolescents at 58 high schools via a Web-based survey. Three-level hierarchical linear models indicated that adolescents who had been bullied were more concerned about both physical and emotional dating violence among students at their school. Schools that were perceived by students as safer were rated as having lower levels of teen dating violence. Older students and male students consistently reported greater concerns about dating violence. These results suggest that adolescents who experience bullying may also have concerns about violence in teen dating relationships. Findings also indicate that schools perceived as being unsafe may be an important context for targeting dating violence prevention efforts. © 2014, American School Health Association.

Influence of air temperature on the first flowering date of Prunus yedoensis Matsum

2014-01-01

Climate change is expected to have a significant effect on the first flowering date (FFD) in plants flowering in early spring. Prunus yedoensis Matsum is a good model plant for analyzing this effect. In this study, we used a degree day model to analyze the effect of air temperatures on the FFDs of P. yedoensis at Wuhan University from a long-time series from 1951 to 2012. First, the starting date (=7 February) is determined according to the lowest correlation coefficient between the FFD and the daily average accumulated degree days (ADD). Second, the base temperature (=−1.2°C) is determined according to the lowest root mean square error (RMSE) between the observed and predicted FFDs based on the mean of 62-year ADDs. Finally, based on this combination of starting date and base temperature, the daily average ADD of every year was calculated. Performing a linear fit of the daily average ADD to year, we find that there is an increasing trend that indicates climate warming from a biological climatic indicator. In addition, we find that the minimum annual temperature also has a significant effect on the FFD of P. yedoensis using the generalized additive model. This study provides a method for analyzing the climate change on the FFD in plants' flowering in early spring. PMID:24558585

Development of an add-on kit for scanning confocal microscopy (Conference Presentation)

NASA Astrophysics Data System (ADS)

Guo, Kaikai; Zheng, Guoan

2017-03-01

Scanning confocal microscopy is a standard choice for many fluorescence imaging applications in basic biomedical research. It is able to produce optically sectioned images and provide acquisition versatility to address many samples and application demands. However, scanning a focused point across the specimen limits the speed of image acquisition. As a result, scanning confocal microscope only works well with stationary samples. Researchers have performed parallel confocal scanning using digital-micromirror-device (DMD), which was used to project a scanning multi-point pattern across the sample. The DMD based parallel confocal systems increase the imaging speed while maintaining the optical sectioning ability. In this paper, we report the development of an add-on kit for high-speed and low-cost confocal microscopy. By adapting this add-on kit to an existing regular microscope, one can convert it into a confocal microscope without significant hardware modifications. Compared with current DMD-based implementations, the reported approach is able to recover multiple layers along the z axis simultaneously. It may find applications in wafer inspection and 3D metrology of semiconductor circuit. The dissemination of the proposed add-on kit under $1000 budget could also lead to new types of experimental designs for biological research labs, e.g., cytology analysis in cell culture experiments, genetic studies on multicellular organisms, pharmaceutical drug profiling, RNA interference studies, investigation of microbial communities in environmental systems, and etc.

To evaluate the efficacy and safety of lacosamide administered as either first add-on or later add-on antiepileptic drug (AED) therapy for patients with uncontrolled partial-onset seizures (POS). In this open-label, multicentre trial, patients with POS initiated oral lacosamide (titrated to 400 mg/day) either as add-on to first AED monotherapy, or as later add-on to 1-3 concomitant AEDs after ≥ 2 previous AEDs. The primary efficacy variable was the proportion of patients achieving seizure freedom for the first 12 weeks of the 24-week Maintenance Phase. 456 patients received ≥ 1 dose of lacosamide (96 as first add-on, 360 as later add-on). In the first add-on cohort, 27/72 (37.5%) patients completed 12 weeks treatment and remained seizure-free; 18/68 (26.5%) remained seizure-free after 24 weeks. 64/91 (70.3%) patients achieved ≥ 50% reduction in seizure frequency during maintenance treatment. This was accompanied by a mean 7.1 ± 16.00 point improvement from Baseline in the Quality of Life Inventory in Epilepsy (QOLIE-31-P) total score for 24-week completers, with improvement reported in all subscales. Most common treatment-emergent adverse events (TEAEs) were dizziness (31.3%) and headache (13.5%). In the later add-on cohort, 39/261 (14.9%) and 29/249 (11.6%) patients remained seizure-free after completing 12 and 24 weeks' treatment, respectively. 178/353 (50.4%) patients achieved ≥ 50% reduction in seizure frequency during maintenance treatment. Mean change in QOLIE-31-P total score was 4.8 ± 14.74 points among 24-week completers. Common TEAEs were dizziness (33.6%), somnolence (15.0%) and headache (11.4%). Lacosamide initiated as first add-on treatment was efficacious and well tolerated in patients with uncontrolled POS. Copyright © 2015 The Authors. Published by Elsevier Ltd.. All rights reserved.

Medicare pioneered add-on payments to facilitate the adoption of innovative technologies under its hospital prospective payment system. US policy makers are now experimenting with broader value-based payment initiatives, but these have not been adjusted for innovation. This article examines the structure, processes, and experience with Medicare's hospital new technology add-on payment program since its inception in 2001 and compares it with analogous payment systems in Germany, France, and Japan. Between 2001 and 2015 CMS approved nineteen of fifty-three applications for the new technology add-on payment program. We found that the program resulted in $201.7 million in Medicare payments in fiscal years 2002-13-less than half the level anticipated by Congress and only 34 percent of the amount projected by CMS. The US program approved considerably fewer innovative technologies, compared to analogous technology payment mechanisms in Germany, France and Japan. We conclude that it is important to adjust payments for new medical innovations within prospective and value-based payment systems explicitly as well as implicitly. The most straightforward method to use in adjusting value-based payments is for the insurer to retrospectively adjust spending targets to account for the cost of new technologies. If CMS made such retrospective adjustments, it would not financially penalize hospitals for adopting beneficial innovations. Project HOPE—The People-to-People Health Foundation, Inc.

Only limited clinical scenarios are grounds for induction of therapeutic hypothermia. Its use in traumatic cardiac arrests, including those from lightning strikes, is not well studied. Nonshockable cardiac arrest rhythms have only recently been included in resuscitation guidelines. We report a case of full neurological recovery with therapeutic hypothermia after a lightning-induced pulseless electrical activity cardiac arrest in an 18-year-old woman. We also review the important pathophysiology of lightning-induced cardiac arrest and neurologic sequelae, elaborate upon the mechanism of therapeutic hypothermia, and add case-based evidence in favor of the use of targeted temperature management in lightning-induced cardiac arrest.

Aerosol is any small particle of matter that rests suspended in the atmosphere. Natural sources, such as deserts, create some aerosols; consumption of fossil fuels and industrial activity create other aerosols. All the microscopic aerosol particles add up to a large amount of material floating in the atmosphere. You can see the particles in the haze that floats over polluted cities. Beyond this visible effect, aerosols can actually lower temperatures. They do this by blocking, or scattering, a portion of the sun's energy from reaching the surface. Because of this influence, scientists study the physical properties of atmospheric aerosols. Reliable numerical models for atmospheric aerosols play an important role in research.

This article has been written as part of a research project investigating the experiences of people with urinary incontinence. In this article a systematic literature analysis combined with excerpts from the study was used to describe and reflect on the best way to conduct interviews on sensitive topics. Ethical aspects are emphasised. These include informed and process consent, different types, places, and phases of such an interview, and reasons for people to participate in such interviews. It is shown that grappling with sensitive and shameful topics can promote recruitment of potential candidates and add depth to qualitative research. As such, sensitive interview topics constitute important quality indicators for qualitative research.

To calculate the near focal distance of different multifocal intraocular lenses (IOLs) as a function of the 2 parameters that are measured before cataract surgery; that is, axial length (AL) and refractive corneal power (keratometry [K]). GB Bietti Foundation IRCCS, Rome, Italy. Noninterventional theoretical study. The IOL power for emmetropia was first calculated in an eye model with the AL ranging from 20 to 30 mm and K from 38 to 48 diopters (D). Then, the predicted myopic refraction for any given IOL add power (from +1.5 to +4.0 D) was calculated, and from this value the near focal distance was obtained. Calculations were also performed for the average eye (K = 43.81 D; AL = 23.65 mm). The near focal distance increased with increasing values of K and AL for each near power add. The near focal distance ranged between 53 cm and 72 cm (21 inches and 28 inches) for a multifocal IOL with +2.50 D, between 44 cm and 60 cm (17 inches and 24 inches) for a multifocal IOL with +3.00 D add, and between 33 cm and 44 cm (13 inches and 18 inches) for a multifocal IOL with +4.00 D add. In the average eye, the near focal distance ranges between 36 cm (near add power = 4.00 D) and 99 cm (near add power = 1.5 D). Longer eyes with steeper corneas showed the longest near focal distance and could experience more difficulties in focusing near objects after surgery. The opposite was true for short hyperopic eyes.

The objective of this study was to assess the efficacy and safety of triple therapy with saxagliptin add-on versus placebo add-on to dapagliflozin plus metformin in adults with type 2 diabetes. Patients on stable metformin (≥1,500 mg/day) for ≥8 weeks with glycated hemoglobin (HbA1c) 8.0-11.5% (64-102 mmol/mol) at screening received open-label dapagliflozin (10 mg/day) plus metformin immediate release (IR) for 16 weeks. Patients with inadequate glycemic control (HbA1c 7-10.5% [53-91 mmol/mol]) were then randomized to receive placebo (n = 153) or saxagliptin 5 mg/day (n = 162) in addition to background dapagliflozin plus metformin IR. The primary efficacy end point was change in HbA1c from baseline to week 24. There was a significantly greater reduction in HbA1c at 24 weeks with saxagliptin add-on (-0.51% [-5.6 mmol/mol]) versus placebo (-0.16% [-1.7 mmol/mol]) add-on to dapagliflozin plus metformin (difference, -0.35% [95% CI -0.52% to -0.18%] and -3.8 [-5.7 to -2.0 mmol/mol], respectively; P < 0.0001). Reductions in fasting plasma glucose and 2-h postprandial glucose were similar between treatment arms. A larger proportion of patients achieved HbA1c <7% (53 mmol/mol) with saxagliptin add-on (35.3%) versus placebo add-on (23.1%) to dapagliflozin plus metformin. Adverse events were similar between treatment groups. Episodes of hypoglycemia were infrequent in both treatment arms, and there were no episodes of major hypoglycemia. Triple therapy with the addition of saxagliptin to dapagliflozin plus metformin was well tolerated and produced significant improvements in HbA1c in patients with type 2 diabetes inadequately controlled with dapagliflozin plus metformin. © 2015 by the American Diabetes Association.

1987-01-01

To determine the frequency of obsessive, compulsive, and schizoid behaviors in Tourette syndrome (TS), we prospectively questioned 246 patients with TS, 17 with attention-deficit disorder (ADD), 15 with ADD due to a TS gene, and 47 random controls. The comparative frequency of obsessive, compulsive, and repetitive behaviors--such as obsessive unpleasant thoughts, obsessive silly thoughts, echolalia, palilalia, touching things excessively, touching things a specific number of times, touching others excessively, sexual touching, biting or hurting oneself, head banging, rocking, mimicking others, counting things, and occasional or frequent public exhibitionism--were significantly more common in TS patients than in controls. The frequency of each of these was much higher for grade 3 (severe) TS. Most of these behaviors also occurred significantly more often in individuals with ADD or in individuals with ADD secondary to TS (ADD 2(0) TS). When these features were combined into an obsessive-compulsive score, 45.4% of TS patients had a score of 4-15, whereas 8.5% of controls had a score of 4 or 5. These results indicate that obsessive-compulsive behaviors are an integral part of the expression of the TS gene and can be inherited as an autosomal dominant trait. Schizoid symptoms, such as thinking that people were watching them or plotting against them, were significantly more common in TS patients than in controls. Auditory hallucinations of hearing voices were present in 14.6% of TS patients, compared with 2.1% of controls (P = .02). These symptoms were absent in ADD patients but present in ADD 2(0) TS patients. These voices were often blamed for telling them to do bad things and were frequently identified with the devil. None of the controls had a total schizoid behavior score greater than 3, whereas 10.9% of the TS patients had scores of 4-10 (P = .02). This frequency increased to 20.6% in the grade 3 TS patients. These quantitative results confirm our clinical impression that some TS patients have paranoid ideations, often feel that people are out to get them, and hear voices. PMID:3479015

The detection of low-level light is a key technology in various experimental scientific studies. As a photon detector, the silicon photomultiplier (SiPM) has gradually become an alternative to the photomultiplier tube (PMT) in many applications in high-energy physics, astroparticle physics, and medical imaging because of its high photon detection efficiency (PDE), good resolution for single-photon detection, insensitivity to magnetic field, low operating voltage, compactness, and low cost. However, primarily because of the geometric fill factor, the PDE of most SiPMs is not very high; in particular, for those SiPMs with a high density of micro cells, the effective area is small, and the bandwidth of the light response is narrow. As a building block of the SiPM, the concept of the backside-illuminated avalanche drift detector (ADD) was first proposed by the Max Planck Institute of Germany eight years ago; the ADD is promising to have high PDE over the full energy range of optical photons, even ultraviolet light and X-ray light, and because the avalanche multiplication region is very small, the ADD is beneficial for the fabrication of large-area SiPMs. However, because of difficulties in design and fabrication, no significant progress had been made, and the concept had not yet been verified. In this paper, preliminary results in the design, fabrication, and performance of a backside-illuminated ADD are reported; the difficulties in and limitations to the backside-illuminated ADD are analyzed.

...CDC is proposing to amend its regulations for the importation of live nonhuman primates (NHPs) by extending existing requirements for the importation of Macaca fascicularis (cynomolgus), Chlorocebus aethiops (African green), and Macaca mulatta (rhesus) monkeys to all NHPs. Filovirus testing will continue to be required only for Old World NHPs. CDC also is proposing to reduce the frequency at which importers of cynomolgus, African green, and rhesus monkeys are required to renew their registrations, (from every 180 days to every two years). CDC proposes to incorporate existing guidelines into the regulations and add new provisions to address: NHPs imported as part of a trained animal act; NHPs imported or transferred by zoological societies; The transfer of NHPs from approved laboratories; and Non-live imported NHP products. CDC is also proposing that all NHPs be imported only through ports of entry where a CDC quarantine station is located.

The use of camera traps is now widespread and their importance in wildlife studies well understood. Camera trap studies can produce millions of photographs and there is a need for software to help manage photographs efficiently. In this paper, we describe a software system that was built to successfully manage a large behavioral camera trap study that produced more than a million photographs. We describe the software architecture and the design decisions that shaped the evolution of the program over the study’s three year period. The software system has the ability to automatically extract metadata from images, and add customized metadata to the images in a standardized format. The software system can be installed as a standalone application on popular operating systems. It is minimalistic, scalable and extendable so that it can be used by small teams or individual researchers for a broad variety of camera trap studies. PMID:25110471

Respirable particulate exposure strongly affects human health, especially for children who lived around industrial area. This study was conducted to evaluate the effect of respirable particulate exposure to lung capacity of children. Study location in this study was Parung Panjang District, area of lead smelter industry and also in Astana Anyar District, area of e-waste processing industry. Thirty children were involved in Astana Anyar District and also thirty children in Parung Panjang District. The control groups were also studied in both areas. Predicted average daily intake (ADD) of respirable particulate was estimated and lung or respiration condition of children was measured by using spirometer. The lung condition of respondents was estimated by FEV1.0 and FVC values. As the result, the predicted ADD of children in lead smelter area is 3 times higher than the predicted ADD of children in e-waste processing area. It was correlated positively with the higher PM2.5 concentration in Parung Panjang District than the PM2.5 concentration in Astana Anyar District. Metals concentration in Parung Panjang was also measured with X-Ray Fluorescence (XRF) in this study and it was clearly state that metals concentration in location study were higher than metals concentration in control area.

We examined whether memantine add-on to antipsychotic treatment is beneficial in schizophrenia treatment. This systematic review and meta-analysis aimed to achieve stronger evidence on the efficacy and safety of memantine add-on for treating schizophrenia. We analyzed double-blind, randomized, placebo-controlled trials of memantine add-on treatment in schizophrenia patients receiving antipsychotics. The primary outcomes were amelioration of negative symptoms and all-cause discontinuation. Dichotomous outcomes are presented as risk ratios (RRs), and continuous outcomes are presented as mean differences (MDs) or standardized mean differences (SMDs). Eight studies (n = 448) were included. Although memantine add-on treatment was superior to placebo for ameliorating negative symptoms (SMD = -0.96, p = 0.006, I 2  = 88%; N = 7, n = 367) in the Positive and Negative Syndrome Scale general subscale (MD = -1.62, p = 0.002, I 2  = 0%; N = 4, n = 151) and Mini-Mental Status Examination score (MD = -3.07, p < 0.0001, I 2  = 21%; N = 3, n = 83), there were no statistically significant differences in the amelioration of overall (SMD = -0.75, p = 0.06, I 2  = 86%; N = 5, n = 271), positive (SMD = -0.46, p = 0.07, I 2  = 80%; N = 7, n = 367), and depressive symptoms (SMD = -0.127, p = 0.326, I 2  = 0%; N = 4, n = 201); all-cause discontinuation (RR = 1.34, p = 0.31, I 2  = 0%; N = 8, n = 448); and individual adverse events (fatigue, dizziness, headache, nausea, constipation) between the groups. For negative symptoms, the significant heterogeneity disappeared when risperidone studies alone were considered (I 2  = 0%). However, memantine add-on treatment remained superior to placebo (SMD = -1.29, p = 0.00001). Meta-regression analysis showed that patient age was associated with memantine-associated amelioration of negative symptoms (slope = 0.171, p = 0.0206). Memantine add-on treatment may be beneficial for treating psychopathological symptoms (especially negative symptoms) in schizophrenia patients. The negative-symptom effect size may be associated with younger adult schizophrenia patients.

With the growing recognition that, for some, significant changes in drinking occur before the first treatment session (i.e., pretreatment change), researchers have called for the careful assessment of when change occurs and its potential impact on mechanism of behavior change (MOBC) research. Using a commonly hypothesized MOBC variable, alcohol abstinence self-efficacy, the primary aim of this study was to examine the effect of pretreatment change on the study of MOBCs. Sixty-three individuals diagnosed with alcohol dependence were recruited to participate in a 12-week cognitive-behavioral treatment. Participants completed weekly assessments of self-efficacy and drinking behaviors. Multilevel time-lagged regression models indicated that pretreatment change significantly moderated the effect of self-efficacy on the number of drinking days, such that among those higher on pretreatment change, higher self-efficacy ratings predicted lower rates of drinking days in the week until the next treatment session. In contrast, pretreatment change did not moderate the effect of self-efficacy on the rate of heavy drinking days. Results from the current study add to a small but growing body of research highlighting the importance of pretreatment change when studying MOBCs. Further, these results provide important insights into the conditions in which self-efficacy may play an important role in treatment outcomes.

Optimal Wind Energy Integration in Large-Scale Electric Grids

NASA Astrophysics Data System (ADS)

Albaijat, Mohammad H.

The major concern in electric grid operation is operating under the most economical and reliable fashion to ensure affordability and continuity of electricity supply. This dissertation investigates the effects of such challenges, which affect electric grid reliability and economic operations. These challenges are: 1. Congestion of transmission lines, 2. Transmission lines expansion, 3. Large-scale wind energy integration, and 4. Phaser Measurement Units (PMUs) optimal placement for highest electric grid observability. Performing congestion analysis aids in evaluating the required increase of transmission line capacity in electric grids. However, it is necessary to evaluate expansion of transmission line capacity on methods to ensure optimal electric grid operation. Therefore, the expansion of transmission line capacity must enable grid operators to provide low-cost electricity while maintaining reliable operation of the electric grid. Because congestion affects the reliability of delivering power and increases its cost, the congestion analysis in electric grid networks is an important subject. Consequently, next-generation electric grids require novel methodologies for studying and managing congestion in electric grids. We suggest a novel method of long-term congestion management in large-scale electric grids. Owing to the complication and size of transmission line systems and the competitive nature of current grid operation, it is important for electric grid operators to determine how many transmission lines capacity to add. Traditional questions requiring answers are "Where" to add, "How much of transmission line capacity" to add, and "Which voltage level". Because of electric grid deregulation, transmission lines expansion is more complicated as it is now open to investors, whose main interest is to generate revenue, to build new transmission lines. Adding a new transmission capacity will help the system to relieve the transmission system congestion, create profit for investors for renting their transmission capacity, and cheaper electricity for end users. We propose a hybrid method based on a heuristic and deterministic method to attain new transmission lines additions and increase transmission capacity. Renewable energy resources (RES) have zero operating cost, which makes them very attractive for generation companies and market participants. In addition, RES have zero carbon emission, which helps relieve the concerns of environmental impacts of electric generation resources' carbon emission. RES are wind, solar, hydro, biomass, and geothermal. By 2030, the expectation is that more than 30% of electricity in the U.S. will come from RES. One major contributor of RES generation will be from wind energy resources (WES). Furthermore, WES will be an important component of the future generation portfolio. However, the nature of WES is that it experiences a high intermittency and volatility. Because of the great expectation of high WES penetration and the nature of such resources, researchers focus on studying the effects of such resources on the electric grid operation and its adequacy from different aspects. Additionally, current market operations of electric grids add another complication to consider while integrating RES (e.g., specifically WES). Mandates by market rules and long-term analysis of renewable penetration in large-scale electric grid are also the focus of researchers in recent years. We advocate a method for high-wind resources penetration study on large-scale electric grid operations. PMU is a geographical positioning system (GPS) based device, which provides immediate and precise measurements of voltage angle in a high-voltage transmission system. PMUs can update the status of a transmission line and related measurements (e.g., voltage magnitude and voltage phase angle) more frequently. Every second, a PMU can provide 30 samples of measurements compared to traditional systems (e.g., supervisory control and data acquisition [SCADA] system), which provides one sample of measurement every 2 to 5 seconds. Because PMUs provide more measurement data samples, PMU can improve electric grid reliability and observability. (Abstract shortened by UMI.)

Space station systems technology study (add-on task). Volume 2: Trade study and technology selection

The current Space Station Systems Technology Study add on task was an outgrowth of the Advanced Platform Systems Technology Study (APSTS) that was completed in April 1983 and the subsequent Space Station System Technology Study completed in April 1984. The first APSTS proceeded from the identification of 106 technology topics to the selection of five for detailed trade studies. During the advanced platform study, the technical issues and options were evaluated through detailed trade processes, individual consideration was given to costs and benefits for the technologies identified for advancement, and advancement plans were developed. An approach similar to that was used in the subsequent study, with emphasis on system definition in four specific technology areas to facilitate a more in depth analysis of technology issues.

Swings and roundabouts: management of jealousy in heterosexual swinging couples.

PubMed

de Visser, Richard; McDonald, Dee

2007-06-01

Swinging involves consensual mutual involvement in extra-dyadic sex. Jealousy in swinging couples is an interesting topic for social psychological research, because it is a common and acceptable response to a romantic partner's real or imagined infidelity. This qualitative study examined the management of jealousy among four active heterosexual swinging couples living in southern England. Participants highlighted the importance of discussion and negotiation to develop a shared couple identity and shared rules and boundaries that allowed them to manage jealousy so that they could better enjoy swinging. Rather than seeking to eliminate jealousy, swingers may manage their feelings of jealousy in order to increase sexual excitement and arousal. This study adds to our understanding of jealousy among swingers and the broader issue of jealousy in intimate relationships.

The article reflects on the ways in which a person-centred approach was used to ensure that people with dementia were given an opportunity to participate in research. The authors discuss three key issues-the importance of including people with dementia in research, informed consent and the possibility of accidental disclosure of diagnosis. The study was an in-depth examination of the ways in which the cancer team manages patients with memory problems and patients with dementia, and the experiences of these patients and their families in accessing outpatient cancer treatment and care in Wales. The study findings will be reported elsewhere. This article aims to add to the small body of existing knowledge within the literature that describes the experiences of researchers in actively involving people with dementia in research.

Using indirect comparisons to compare interventions within a Cochrane review: a tool for comparative effectiveness research.

Assessing relative performance among competing interventions is an important part of comparative effectiveness research. Bayesian indirect comparisons add information to existing Cochrane reviews, such as which intervention is likely to perform best. However, heterogeneity variance priors may influence results and, potentially, clinical guidance. We highlight the features of Bayesian indirect comparisons using a case study of a Cochrane review update in asthma care. The probability that one self-management educational intervention outperforms others is estimated. Simulation studies investigate the effect of heterogeneity variance prior distributions. Results suggest a 55% probability that individual education is best, followed by combination (39%) and group (6%). The intervention with few trials was sensitive to prior distributions. Bayesian indirect comparisons updates of Cochrane reviews are valuable comparative effectiveness research tools.

Human urine can be concentrated up to four times higher than that of the plasma. Urine concentrating mechanism has attracted for a long time. However, studies in the field are now picking up momentum due to recent breakthrough discoveries using molecular biology techniques. Vasopressin-regulated water channel in the apical membrane of the collecting duct and water channel in the basolateral side of the membrane were cloned. cloned. Osmolality-dependent chloride channel in the thin ascending limb of Henle was also cloned. In addition, vasopressin-regulated urea transporter was found in the collecting duct. These newly discovered channels and transporter should be playing important physiological roles in urine concentrating mechanism. Furthermore, recent findings on osmolytes and their transporters also add to the list of urine concentrating mechanisms.

Understanding the complex relationships among factors that may predict the outcomes of young adults with autism spectrum disorder (ASD) is of utmost importance given the increasing population undergoing and anticipating the transition to adulthood. With a sample of youth with ASD (n = 1170) from the National Longitudinal Transition Study-2, structural equation modeling techniques were used to test parent expectations as a mediator of young adult outcomes (i.e., employment, residential independence, social participation) in a longitudinal analysis. The mediation hypothesis was confirmed; family background and functional performance variables significantly predicted parent expectations which significantly predicted outcomes. These findings add context to previous studies examining the role of parent expectations on young adult outcomes and inform directions for family-centered interventions and future research.

A vector map is a terrain representation with a vector-structured geometry. Molenaar formulated an object-oriented formal data structure for 3D single valued vector maps. This FDS is implemented in a database (Oracle). In this study we describe a methodology for visualizing a FDS-based database and manipulating the image. A data set retrieved by querying the database is converted into an import file for a drawing application. An objective of this study is that an end-user can alter and add terrain objects in the image. The drawing application creates an export file, that is compared with the import file. Differences between these files result in updating the database which involves checks on consistency. In this study Autocad is used for visualizing and manipulating the image of the data set. A computer program has been written for the data exchange and conversion between Oracle and Autocad. The data structure of the FDS is compared to the data structure of Autocad and the data of the FDS is converted into the structure of Autocad equal to the FDS.

To evaluate the efficacy and safety of linagliptin vs placebo as add-on to empagliflozin and metformin in patients with type 2 diabetes. Patients with inadequate glycaemic control despite stable-dose metformin received open-label empagliflozin 10 mg (study 1) or 25 mg (study 2) as add-on therapy for 16 weeks. Subsequently, those with HbA1c ≥7.0 and ≤10.5% (>53 and ≤91 mmol/mol) (N = 482) were randomized to 24 weeks' double-blind, double-dummy treatment with linagliptin 5 mg or placebo in study 1, or to linagliptin 5 mg or placebo in study 2; all patients continued treatment with metformin and empagliflozin 10 mg (study 1) or metformin and empagliflozin 25 mg (study 2). The primary endpoint was change from baseline (defined as the last value before first intake of randomized, double-blind treatment) in HbA1c at week 24. At week 24, HbA1c (mean baseline 7.82-8.04 [62-64 mmol/mol]) was significantly reduced with linagliptin vs placebo; adjusted mean (SE) differences in change from baseline in HbA1c with linagliptin vs placebo were -.32% (.10) (-3.59 [1.08] mmol/mol) ( P = .001) for patients on empagliflozin 10 mg and metformin, and -0.47% (0.10) (-5.15 [1.04] mmol/mol) ( P < 0.001) for patients on empagliflozin 25 mg and metformin. Adverse events were reported in more patients receiving placebo than in those receiving linagliptin: 55.5% vs 48.4% in study 1 and 58.9% vs 52.7% in study 2. Linagliptin as add-on to empagliflozin and metformin for 24 weeks improved glycaemic control vs placebo, and was well tolerated. © 2016 John Wiley & Sons Ltd.

Combination therapy using acetylcholinesterase inhibitors (AChEIs) and cilostazol is of unknown efficacy for patients with Alzheimer's disease (AD). We explored the therapeutic responses by using a case-control study, which was conducted in Taiwan. We enrolled 30 participants with stable AD who were receiving cilostazol (50 mg) twice per day as an add-on therapy combined with AChEIs, and 30 participants as controls who were not receiving cilostazol as an add-on therapy. The therapeutic responses were measured using neuropsychological assessments and analyzed in relation to cilostazol use, apolipoprotein E genotype, and demographic characteristics. Mini-mental state examination (MMSE) and clinical dementia rating sum of boxes (CDR-SB) were administered at the outset of the study and 12 months later. Multiple logistic regression analysis was used to estimate the association between the therapeutic response and cilostazol use. For the therapeutic indicator of cognition, Cilostazol use (adjusted odds ratio (aOR) = 0.17, 95% confidence interval (CI) = 0.03-0.80), initial CDR-SB score (aOR = 2.06, 95% CI = 1.31-3.72), and initial MMSE score (aOR = 1.41, 95% CI = 1.11-1.90), but not age, sex, education, or ApoE ε4 status, were significantly associated with poor therapeutic outcomes. For the therapeutic indicator of global status, no significant association was observed between the covariates and poor therapeutic outcomes. Cilostazol may reduce the decline of cognitive function in stable AD patients when applied as an add-on therapy.

Tripp, Erin A; Fatimah, Siti

2012-06-01

Anatomical and morphological features of Satanocrater were studied to test hypotheses of xeric adaptations in the genus, which is endemic to arid tropical Africa. These features, together with molecular data, were used to test the phylogenetic placement of Satanocrater within the large plant family Acanthaceae. We undertook a comparative study of four species of Satanocrater. Carbon isotope ratios were generated to test a hypothesis of C(4) photosynthesis. Molecular data from chloroplast (trnG-trnS, trnG-trnR, psbA-trnH) and nuclear (Eif3E) loci were used to test the placement of Satanocrater within Acanthaceae. Anatomical features reflecting xeric adaptations of species of Satanocrater included a thick-walled epidermis, thick cuticle, abundant trichomes and glandular scales, stomata overarched by subsidiary cells, tightly packed mesophyll cells, and well-developed palisade parenchyma on both leaf surfaces. Although two species had enlarged bundle sheath cells, a feature often implicated in C(4) photosynthesis, isotope ratios indicated all species of Satanocrater use the C(3) pathway. Molecular data resolved Satanocrater within tribe Ruellieae with strong support. Within Ruellieae, our data suggest that pollen morphology of Satanocrater may represent an intermediate stage in a transition series. Anatomical and morphological features of Satanocrater reflect adaptation to xeric environments and add new information about the biology of xerophytes. Morphological and molecular data place Satanocrater in the tribe Ruellieae with confidence. This study adds to our capacity to test hypotheses of broad evolutionary and ecological interest in a diverse and important family of flowering plants.

The Epstein-Barr Virus Episome Maneuvers between Nuclear Chromatin Compartments during Reactivation

ABSTRACT The human genome is structurally organized in three-dimensional space to facilitate functional partitioning of transcription. We learned that the latent episome of the human Epstein-Barr virus (EBV) preferentially associates with gene-poor chromosomes and avoids gene-rich chromosomes. Kaposi's sarcoma-associated herpesvirus behaves similarly, but human papillomavirus does not. Contacts on the EBV side localize to OriP, the latent origin of replication. This genetic element and the EBNA1 protein that binds there are sufficient to reconstitute chromosome association preferences of the entire episome. Contacts on the human side localize to gene-poor and AT-rich regions of chromatin distant from transcription start sites. Upon reactivation from latency, however, the episome moves away from repressive heterochromatin and toward active euchromatin. Our work adds three-dimensional relocalization to the molecular events that occur during reactivation. Involvement of myriad interchromosomal associations also suggests a role for this type of long-range association in gene regulation. IMPORTANCE The human genome is structurally organized in three-dimensional space, and this structure functionally affects transcriptional activity. We set out to investigate whether a double-stranded DNA virus, Epstein-Barr virus (EBV), uses mechanisms similar to those of the human genome to regulate transcription. We found that the EBV genome associates with repressive compartments of the nucleus during latency and with active compartments during reactivation. This study advances our knowledge of the EBV life cycle, adding three-dimensional relocalization as a novel component to the molecular events that occur during reactivation. Furthermore, the data add to our understanding of nuclear compartments, showing that disperse interchromosomal interactions may be important for regulating transcription. PMID:29142137

Unlike bioethics mediators who are employed by healthcare organizations as outside consultants, mediators who are embedded in an institution must be authorized to chronicle a clinical ethics consultation (CEC) or a mediation in a patient's medical chart. This is an important privilege, as the chart is a legal document. In this article I discuss this important part of a bioethics mediator's tool kit in my presentation of a case illustrating how bioethics mediation may proceed, and what this approach using both bioethics and mediation may add.

This article reviews diagnostic imaging tests and injections that provide important information for clinical management of patients with sports-related hip pain. In the evaluation of sports-related hip symptoms, MR arthrography is often used to evaluate intraarticular pathology of the hip. The addition of short- and long-acting anesthetic agents with the MR arthrography injection adds additional information that can distinguish between symptomatic and asymptomatic imaging findings. Osseous abnormalities can be characterized with radiography, MRI, or CT. Ultrasound is important in the assessment of iliopsoas abnormalities, including tendon snapping, and to guide diagnostic anesthetic injection.

This study seeks to add to current literature a descriptive account of the lived experience of radiographers' transition to, and experiences of, management roles and identifies additional resources and support that are perceived as being beneficial for this transition. This study employed a descriptive phenomenological stance. Using purposive sampling, six South-East Queensland based private practice radiology managers, who had held their position for longer than 3 months, participated in audiotape recorded in-depth interviews exploring their transition to, and experiences of management in radiology. Thematic analysis was used to describe and make meaning of the data. Overall, five central themes emerged through thematic analysis of the data. The results indicate that all participants' had an underlying drive to succeed during their role transition and highlight the importance of a comprehensive orientation by a mentor; the training and support to enable preparation for the role, especially in the area of people management skills and communication; the importance of access to networking opportunities and the importance of concise expectations from higher management. Role transition can be marred with uncertainty, however; key suggestions indicate the importance of having support mechanisms in place before, during and after transitioning to a managerial role.

Objectives. To explore effectiveness and mechanisms of electroacupuncture (EA) add-on treatment in Parkinson's disease (PD) patients. Methods. Fifty PD patients were randomly assigned to drug plus EA (D + EA) group and drug alone (D) group. Subjects in D + EA group received stimulation in points of bilateral fengfu, fengchi, hegu, and central dazhui. Participants were evaluated by scales for motor and nonmotor symptoms. Levels of neuroinflammatory factors and neurotransmitters in serum were detected. Results. EA add-on treatment remarkably reduced scores of Unified Parkinson's Disease Rating Scale (UPDRS) III and its subitems of tremor, rigidity, and bradykinesia and conspicuously decreased UPDRS III scores in patients with bradykinesia-rigidity and mixed types and mild severity. Depression and sleep disturbances were eased, which were reflected by decreased scores of Hamilton Depression Rating Scale, Pittsburgh Sleep Quality Index, and elevated noradrenaline level. Effects of EA add-on treatment on motor symptoms and sleep disturbances were superior to drug alone treatment, markedly improving life quality of PD patients. EA add-on treatment decreased nitric oxide level in serum. Conclusions. EA add-on treatment is effective on most motor symptoms and some nonmotor symptoms and is particularly efficacious in PD patients at early stage. Antineuroinflammation may be a mechanism of EA add-on treatment. PMID:26351515

The hospital microbiome project: meeting report for the UK science and innovation network UK-USA workshop ‘beating the superbugs: hospital microbiome studies for tackling antimicrobial resistance’, October 14th 2013

PubMed Central

2014-01-01

The UK Science and Innovation Network UK-USA workshop ‘Beating the Superbugs: Hospital Microbiome Studies for tackling Antimicrobial Resistance’ was held on October 14th 2013 at the UK Department of Health, London. The workshop was designed to promote US-UK collaboration on hospital microbiome studies to add a new facet to our collective understanding of antimicrobial resistance. The assembled researchers debated the importance of the hospital microbial community in transmission of disease and as a reservoir for antimicrobial resistance genes, and discussed methodologies, hypotheses, and priorities. A number of complementary approaches were explored, although the importance of the built environment microbiome in disease transmission was not universally accepted. Current whole genome epidemiological methods are being pioneered in the UK and the benefits of moving to community analysis are not necessarily obvious to the pioneers; however, rapid progress in other areas of microbiology suggest to some researchers that hospital microbiome studies will be exceptionally fruitful even in the short term. Collaborative studies will recombine different strengths to tackle the international problems of antimicrobial resistance and hospital and healthcare associated infections.

Earthworm in the 21st century

Earthworm (Johnson et al., 1995) is a fully open-source earthquake data acquisition and processing package that is in widespread use through out the world. Earthworm includes basic seismic data acquistion for the majority of the dataloggers currently available and provides network transport mechanisms and common formats as output for data transferral. In addition, it comes with network seismology tools to compute network detections, perform automated arrival picking, and automated hypocentral and magnitude estimations. More importantly it is an open and free framework in the C-programming language that can be used to create new modules that process waveform and earthquake data in near real time. The number of Earthworm installations is growing annually as are the number of contributions to the system. Furthermore its growth into other areas of waveform data acquistion (namely Geomagnetic observatories and Infrasound arrays) show its adaptability to other waveform technologies and processing strategies. In this presentation we discuss the coming challenges to growing Earthworm and new developments in its use; namely the open source add-ons that have become interfaces to Earthworm's core. These add-ons include GlowWorm, MagWorm, Hydra, SWARM, Winston, EarlyBird, Iworm, and most importantly, AQMS (formerly known as CHEETAH). The AQMS, ANSS Quake Monitoring System, is the Earthworm system created in California which has now been installed in the majority of Regional Seismic Networks (RSNs) in the United States. AQMS allows additional real-time and post-processing of Earthworm generated data to be stored and manipulated in a database using numerous database oriented tools. The use of a relational database for persistence provides users with the ability to implement configuration control and research capabilities not available in earlier Earthworm add-ons. By centralizing on AQMS, the RSNs will be able to leverage new developments by easily sharing Earthworm and AQMS modules and avoid the duplication and one-off/custom developments of the past.

Assessment of antimicrobial use (AMU) is vital for interpreting the origin of changes in antimicrobial resistance (AMR). The objectives of the present study were to estimate the association between AMU determined using on-farm treatment records (TR) and inventory of empty drug containers (INV). Herds were selected to represent Canadian dairy farms. Producers were asked to record animal health events and treatments on a standard General Health Event form. For inventory data, 40-L receptacles were placed at various locations considered convenient to deposit all empty drug containers. Antimicrobial defined-daily dosages (ADD) were calculated for 51 Canadian herds using the 2 methods. Estimation of AMU was 31,840 ADD using the INV and 14,487 ADD using the TR, indicating that for every TR entry, 2.20 times more treatments were observed using the INV. Mastitis, reproductive conditions, and dry cow therapy were the most frequent reasons for antimicrobial therapy when assessing TR. For all antimicrobials evaluated, mean ADD was higher using the INV versus TR. Regardless, a strong positive correlation (0.80) was observed between the 2 methods, indicating that herds with increased number of ADD recorded using the INV also had increased number of ADD recorded using TR. Furthermore, a positive association was observed for the 6 most commonly used antimicrobials. In comparison to methods used in surveillance programs on AMU in livestock that assume a constant use in all herds (i.e., sales data), INV provided a herd-level specific quantity of AMU positively correlated with AMU recorded at the animal level in general. The INV was easy to implement and provided a measure of total AMU in the herd. Availability of such information would be valuable for interpreting changes in AMR at the herd level and enabling evaluation of interventions for decreasing AMR.

An original method able to fully characterize high-Q resonators in an add-drop configuration has been implemented. The method is based on the study of two cavity ringdown (CRD) signals, which are produced at the transmission and drop ports by wavelength sweeping a resonance in a time interval comparable with the photon cavity lifetime. All the resonator parameters can be assessed with a single set of simultaneous measurements. We first developed a model describing the two CRD output signals and a fitting program able to deduce the key parameters from the measured profiles. We successfully validated the model with an experiment based on a fiber ring resonator of known characteristics. Finally, we characterized a high-Q, home-made, MgF2 whispering gallery mode disk resonator in the add-drop configuration, assessing its intrinsic and coupling parameters.

Limited literature examines mathematics education for students with mild intellectual disability. This study investigated the effects of using the Virtual-Abstract instructional sequenceto teach middle school students, predominantly with mild intellectual disability, to add fractions of unlike denominators. Researchers used a multiple probe across participants design to determine if a functional relation existed between the Virtual-Abstract instructional sequence strategy and students' ability to add fractions with unlike denominators. The study of consisted of three-to-nine baseline sessions, 6-11 intervention sessions, and two maintenance sessions for each student. Data were collected on accuracy across five addition of fractions with unlike denominators problems. The VA instructional strategy was effective in thestudents to add fractions with unlike denominators; a functional relation existed between the VA instructional sequence and adding fractions with unlike denominators for three of the four students. The Virtual-Abstract instructional sequencemay be appropriate to support students with mild intellectual disability in learning mathematics, especially when drawing or representing the mathematical concepts may prove challenging.

Traditionally, steroids other than testosterone are considered to be synthetic, anabolic steroids. Nevertheless, in stallions, it has been shown that β-Bol can originate from naturally present testosterone. Other precursors, including phytosterols from feed, have been put forward to explain the prevalence of low levels of steroids (including β-Bol and ADD) in urine of mares and geldings. However, the possible biotransformation and identification of the precursors has thus far not been investigated in horses. To study the possible endogenous digestive transformation, in vitro simulations of the horse hindgut were set up, using fecal inocula obtained from eight different horses. The functionality of the in vitro model was confirmed by monitoring the formation of short-chain fatty acids and the consumption of amino acids and carbohydrates throughout the digestion process. In vitro digestion samples were analyzed with a validated UHPLC-MS/MS method. The addition of β-Bol gave rise to the formation of ADD (androsta-1,4-diene-3,17-dione) or αT. Upon addition of ADD to the in vitro digestions, the transformation of ADD to β-Bol was observed and this for all eight horses' inocula, in line with previously obtained in vivo results, again confirming the functionality of the in vitro model. The transformation ratio proved to be inoculum and thus horse dependent. The addition of pure phytosterols (50% β-sitosterol) or phytosterol-rich herbal supplements on the other hand, did not induce the detection of β-Bol, only low concentrations of AED, a testosterone precursor, could be found (0.1 ng/mL). As such, the digestive transformation of ADD could be linked to the detection of β-Bol, and the consumption of phytosterols to low concentrations of AED, but there is no direct link between phytosterols and β-Bol.

Prolonged cardiac activity that exceeds metabolic needs can be detrimental for somatic health. Psychological stress could result in such "additional cardiac activity." In this study, we examined whether prolonged additional reductions in heart rate variability (AddHRVr) can be measured in daily life with an algorithm that filters out changes in HRV that are purely due to metabolic demand, as indexed by movement, using a brief calibration procedure. We tested whether these AddHRVr periods were related to worry, stress, and negative emotions. Movement and the root of the mean square of successive differences (RMSSD) in heart rate were measured during a calibration phase and the subsequent 24 h in 32 participants. Worry, stress, explicit and implicit emotions were assessed hourly using smartphones. The Levels of Emotional Awareness Scale and resting HRV were used to account for individual differences. During calibration, person-specific relations between movement and RMSSD were determined. The 24-h data were used to detect prolonged periods (i.e., 7.5 min) of AddHRVr. AddHRVr periods were associated with worrying, with decreased explicit positive affect, and with increased tension, but not with the frequency of stressful events or implicit emotions. Only in people high in emotional awareness and high in resting HRV did changes in AddHRVr covary with changes in explicit emotions. The algorithm can be used to capture prolonged reductions in HRV that are not due to metabolic needs. This enables the real-time assessment of episodes of potentially detrimental cardiac activity and its psychological determinants in daily life.

To improve the androst-1,4-diene-3,17-dione (ADD) production from phytosterol by Mycobacterium neoaurum JC-12, fructose was firstly found favorable as the initial carbon source to increase the biomass and eliminate the lag phase of M. neoaurum JC-12 in the phytosterol transformation process. Based on this phenomenon, two-stage fermentation by using fructose as the initial carbon source and feeding glucose to maintain strain metabolism was designed. By applying this strategy, the fermentation duration was decreased from 168 h to 120 h with the ADD productivity increased from 0.071 g/(L·h) to 0.108 g/(L·h). Further, three-stage fermentation by adding phytosterol to improve ADD production at the end of the two-stage fermentation was carried out and the final ADD production reached 18.6 g/L, which is the highest reported ADD production using phytosterol as substrate. Thus, this strategy provides a possible way in enhancing the ADD production in pharmaceutical industry. PMID:26352898

Cotillon, Suzanne E.; Mathis, Melissa L.

2017-02-15

The Rapid Land Cover Mapper is an Esri ArcGIS® Desktop add-in, which was created as an alternative to automated or semiautomated mapping methods. Based on a manual photo interpretation technique, the tool facilitates mapping over large areas and through time, and produces time-series raster maps and associated statistics that characterize the changing landscapes. The Rapid Land Cover Mapper add-in can be used with any imagery source to map various themes (for instance, land cover, soils, or forest) at any chosen mapping resolution. The user manual contains all essential information for the user to make full use of the Rapid Land Cover Mapper add-in. This manual includes a description of the add-in functions and capabilities, and step-by-step procedures for using the add-in. The Rapid Land Cover Mapper add-in was successfully used by the U.S. Geological Survey West Africa Land Use Dynamics team to accurately map land use and land cover in 17 West African countries through time (1975, 2000, and 2013).

Clinically relevant reductions in HbA1c without hypoglycaemia: results across four studies of saxagliptin.

Karyekar, C S; Frederich, R; Ravichandran, S

2013-08-01

In four 24-week controlled studies, the antihyperglycaemic efficacy of saxagliptin was demonstrated in patients with type 2 diabetes mellitus as add-on therapy to glyburide, a thiazolidinedione, or metformin, and when used in initial combination with metformin vs. metformin monotherapy in drug-naive patients. Data from these studies were analysed to compare the proportions of patients who achieved specific reductions from baseline in glycated haemoglobin [HbA(1c); reductions of ≥ 0.5% and ≥ 0.7% in all studies (prespecified); reductions ≥ 1.0% in the add-on studies and ≥ 1.0% to ≥ 2.5% in the initial combination study (post hoc)] for saxagliptin vs. comparator at week 24. We report overall rates of glycaemic response defined by these reductions in HbA(1c) and rates of response without experiencing hypoglycaemia. Large glycaemic response rates were higher with saxagliptin 2.5 and 5 mg/day than with comparator (HbA(1c) ≥ 1.0%, 31.7-50.3% vs. 10.3-20.0%) as add-on therapy and higher with saxagliptin 5 mg/day as initial combination with metformin than with metformin monotherapy (HbA(1c) ≥ 2.0%, 68.3% vs. 49.8%) in drug-naive patients. Addition of saxagliptin was associated with a low incidence of hypoglycaemia; overall response rates and response rates excluding patients who experienced hypoglycaemia were similar. Analysis of several demographic and baseline clinical variables revealed no consistent correlations with response to saxagliptin. Whether receiving saxagliptin as an add-on therapy to glyburide, a thiazolidinedione, or metformin or in initial combination with metformin, a greater percentage of patients achieve clinically relevant large reductions in HbA(1c) vs. comparator, with a low incidence of hypoglycaemia. © 2013 Bristol-Myers Squibb Co.

Theoretical and experimental studies relevant to interpretation of auroral emissions

NASA Technical Reports Server (NTRS)

Keffer, Charles E.

1991-01-01

The accomplishments achieved over the past year are detailed with emphasis on the interpretation or auroral emissions and studies of potential spacecraft-induced contamination effects. Accordingly, the research was divided into two tasks. The first task is designed to add to the understanding of space vehicle induced external contamination. An experimental facility for simulation of the external environment for a spacecraft in low earth orbit was developed. The facility was used to make laboratory measurements of important phenomena required for improving the understanding of the space vehicle induced external environment and its effect on measurement of auroral emissions from space-based platforms. A workshop was sponsored to provide a forum for presentation of the latest research by nationally recognized experts on space vehicle contamination and to discuss the impact of this research on future missions involving space-based platforms. The second task is to add an ab initio auroral calculation to the extant ionospheric/thermospheric global modeling capabilities. Once the addition of the code was complete, the combined model was to be used to compare the relative intensities and behavior of various emission sources (dayglow, aurora, etc.). Such studies are essential to an understanding of the types of vacuum ultraviolet (VUV) auroral images which are expected to be available within two years with the successful deployment of the Ultraviolet Imager (UVI) on the ISTP POLAR spacecraft. In anticipation of this, the second task includes support for meetings of the science working group for the UVI to discuss operational and data analysis needs. Taken together, the proposed tasks outline a course of study designed to make significant contributions to the field of space-based auroral imaging.

Extracurricular activities in young applicants' résumés: what are the motives behind their involvement?

PubMed

Roulin, Nicolas; Bangerter, Adrian

2013-01-01

Applicants use résumés to demonstrate their knowledge, skills, abilities, and other personal characteristics (KSAOs) to recruiters, through education and job-related or non-job-related experiences. But research suggests that the situation for young applicants is especially competitive, since they increasingly enter the labour market with similar educational credentials and limited job-related experience. They may thus use non-job-related experiences, such as participation in extracurricular activities (ECAs) during their studies, to demonstrate KSAOs to recruiters, but also to add distinction and value to their credentials. ECAs may therefore become more important in the selection of young applicants. Yet few studies have undertaken a comprehensive and systematic analysis of the relationships students have with these activities. The purpose of this study was to investigate to what extent students' involvement in ECAs is due to internal (e.g., passion) or external (e.g., résumé-building) motives, and what factors influence these motives. Results from a study with 197 students suggest that students engage in ECAs mainly out of internal motives. But external motives are stronger for activities started closer to entering the labour market, for students active in associative or volunteering activities (as compared to sports or artistic activities), and for students holding leadership positions in their activities. Our results suggest that labour market pressure may be a key component of applicants' involvement in ECAs. Also, organizations and recruiters may want to consider that students tend not to engage in ECAs purely out of internal motives, but also to add value to their credentials and match employers' expectations.

A Political History of Medicare and Prescription Drug Coverage

PubMed Central

Oliver, Thomas R; Lee, Philip R; Lipton, Helene L

2004-01-01

This article examines the history of efforts to add prescription drug coverage to the Medicare program. It identifies several important patterns in policymaking over four decades. First, prescription drug coverage has usually been tied to the fate of broader proposals for Medicare reform. Second, action has been hampered by divided government, federal budget deficits, and ideological conflict between those seeking to expand the traditional Medicare program and those preferring a greater role for private health care companies. Third, the provisions of the Medicare Prescription Drug, Improvement, and Modernization Act of 2003 reflect earlier missed opportunities. Policymakers concluded from past episodes that participation in the new program should be voluntary, with Medicare beneficiaries and taxpayers sharing the costs. They ignored lessons from past episodes, however, about the need to match expanded benefits with adequate mechanisms for cost containment. Based on several new circumstances in 2003, the article demonstrates why there was a historic opportunity to add a Medicare prescription drug benefit and identify challenges to implementing an effective policy.

The aim of this study is to measure the on- and off-responses and their response asymmetries elicited by sawtooth stimuli in normal subjects and glaucoma patients. Furthermore, the correlation between the ERGs and other functional and structural parameters are investigated. Full-field stimuli were produced using a Ganzfeld bowl with Light Emitting Diodes (LEDs) as light sources. On- and off-response ERGs were recorded from 17 healthy subjects, 12 pre-perimetric and 15 perimetric glaucoma patients using 4-Hz luminance rapid-on and rapid-off sawtooth stimuli (white light; mean luminance 55 cd/m(2)) at 100% contrast. The on- and off-responses were added to study response asymmetries. In addition, flash ERGs were elicited by red stimuli (200 cd/m(2)) on a blue background (10 cd/m(2)). The mean deviations (MD) of the visual field defects were obtained by standard automated perimetry. The retinal nerve fibre layer thickness (RNFLT) was measured with Spectral Domain Optical Coherence Tomography (SOCT). We studied the correlation between ERG response amplitudes, visual field mean deviation (MDs) and RNFLT values. The on-responses showed an initial negative (N-on) followed by a positive (P-on), a late positive (LP-on) and a late negative responses (LN-on). The off-responses showed an initial positive (P-off) a late positive (LP-off) and a late negative response (LN-off). The addition of on- and off-responses revealed an initial positive (P-add) and a late negative response (LN-add). The on-response components (N-on, P-on and LN-on) in the glaucoma patients were relatively similar to those of the control subjects. However, the LP-on was significantly elevated (p = 0.03) in perimetric patients. The LP-off was significantly elevated (p < 0.001), and the amplitude of LN-off was significantly reduced in perimetric patients (p = 0.02). The LN-add amplitude was significantly reduced (p < 0.001) and delayed (p = 0.03) in perimetric patients. The amplitudes of the LN-off and LN-add ERG components were significantly correlated with the PhNR in the flash ERG (LN-off: p = 0.01; LN-add: p < 0.001) and with RNFLT (LN-off: p = 0.006; LN-add: p = 0.001). On- and off-response ERGs and their response asymmetries, elicited by sawtooth stimuli, are altered in the glaucoma patients. The late components are affected. Changes in the late negative components are correlated with structural and other functional changes.

In addition to dopaminergic hyperactivity, hypofunction of the N-methyl-d-aspartate receptor (NMDAR) has an important role in the pathophysiology of schizophrenia. Enhancing NMDAR-mediated neurotransmission is considered a novel treatment approach. To date, several trials on adjuvant NMDA-enhancing agents have revealed beneficial, but limited, efficacy for positive and negative symptoms and cognition. Another method to enhance NMDA function is to raise the levels of d-amino acids by blocking their metabolism. Sodium benzoate is a d-amino acid oxidase inhibitor. To examine the clinical and cognitive efficacy and safety of add-on treatment of sodium benzoate for schizophrenia. A randomized, double-blind, placebo-controlled trial in 2 major medical centers in Taiwan composed of 52 patients with chronic schizophrenia who had been stabilized with antipsychotic medications for 3 months or longer. Six weeks of add-on treatment of 1 g/d of sodium benzoate or placebo. The primary outcome measure was the Positive and Negative Syndrome Scale (PANSS) total score. Clinical efficacy and adverse effects were assessed biweekly. Cognitive functions were measured before and after the add-on treatment. Benzoate produced a 21% improvement in PANSS total score and large effect sizes (range, 1.16-1.69) in the PANSS total and subscales, Scales for the Assessment of Negative Symptoms-20 items, Global Assessment of Function, Quality of Life Scale and Clinical Global Impression and improvement in the neurocognition subtests as recommended by the National Institute of Mental Health's Measurement and Treatment Research to Improve Cognition in Schizophrenia initiative, including the domains of processing speed and visual learning. Benzoate was well tolerated without significant adverse effects. Benzoate adjunctive therapy significantly improved a variety of symptom domains and neurocognition in patients with chronic schizophrenia. The preliminary results show promise for d-amino acid oxidase inhibition as a novel approach for new drug development for schizophrenia.

From Bench to Bedside: A communal utility value intervention to enhance students' biomedical science motivation.

PubMed

Brown, Elizabeth R; Smith, Jessi L; Thoman, Dustin B; Allen, Jill M; Muragishi, Gregg

2015-11-01

Motivating students to pursue science careers is a top priority among many science educators. We add to the growing literature by examining the impact of a utility value intervention to enhance student's perceptions that biomedical science affords important utility work values. Using an expectancy-value perspective we identify and test two types of utility value: communal (other-oriented) and agentic (self-oriented). The culture of science is replete with examples emphasizing high levels of agentic value, but communal values are often (stereotyped as) absent from science. However, people in general want an occupation that has communal utility. We predicted and found that an intervention emphasizing the communal utility value of biomedical research increased students' motivation for biomedical science (Studies 1-3). We refined whether different types of communal utility value (working with, helping, and forming relationships with others) might be more or less important, demonstrating that helping others was an especially important predictor of student motivation (Study 2). Adding agentic utility value to biomedical research did not further increase student motivation (Study 3). Furthermore, the communal value intervention indirectly impacted students' motivation because students believed that biomedical research was communal and thus subsequently more important (Studies 1-3). This is key, because enhancing student communal value beliefs about biomedical research (Studies 1-3) and science (Study 4) was associated both with momentary increases in motivation in experimental settings (Studies 1-3) and increased motivation over time among students highly identified with biomedicine (Study 4). We discuss recommendations for science educators, practitioners, and faculty mentors who want to broaden participation in science.

Evaluating the usability of a single UK community acquired brain injury (ABI) rehabilitation service website: implications for research methodology and website design.

Information provision is an important resource for those living with acquired brain injury (ABI) and their families. Web-based health information services are now common additions to health service provision. Ideally, they should be easy to use and provide useful, relevant and accurate information. ABI injuries do not affect individuals in the same way, and survivors can have a wide range of abilities and impairments. Therefore, any informational resource intended for this group should take account of their needs and help to compensate for their limitations. This pilot study recruited a group of individuals with ABI (of a median Extended Glasgow Outcome Scale rating of "lower moderate disability") who were clients of a UK National Health Service rehabilitation service and asked them to assess a specialised website provided by that service and hosted by their employing Primary Care Trust organisation. Participants completed a practical task and then gave their opinions on various aspects of website design, and content. They were also asked to suggest improvements and recommend additions. Overall the results were favourable. However, improvements in the legibility, layout and writing style were identified. There were also requests to add more information on the existing topics and add additional topics. The discussion also evaluates the utility of the methodology and the implications of the results for others considering constructing their own website.

Silicon photonics has gained interest for its potential to provide higher efficiency, bandwidth and reduced power consumption compared to electrical interconnects in datacenters and high performance computing environments. However, it is well known that silicon photonic devices suffer from temperature fluctuations due to silicon's high thermo-optic coefficient and therefore, temperature control in many applications is required. Here we present an athermal optical add-drop multiplexer fabricated from ring resonators. We used a sol-gel inorganic-organic hybrid material as an alternative to previously used materials such as polymers and titanium dioxide. In this work we studied the thermal curing parameters of the sol-gel and their effect on thermal wavelength shift of the rings. With this method, we were able to demonstrate a thermal shift down to -6.8 pm/°C for transverse electric (TE) polarization in ring resonators with waveguide widths of 325 nm when the sol-gel was cured at 130°C for 10.5 hours. We also achieved thermal shifts below 1 pm/°C for transverse magnetic (TM) polarization in the C band under different curing conditions. Curing time compared to curing temperature shows to be the most important factor to control sol-gel's thermo-optic value in order to obtain an athermal device in a wide temperature range.

2016-07-01

To assess retention, tolerability, and safety, efficacy and effects on quality of life (QoL) of eslicarbazepine acetate (ESL) add-on treatment over 6 months in a real-world adult population with partial-onset seizures. This non-interventional, multicenter, prospective study was performed in eight European countries. Adult patients (n = 247) for whom the physician had decided to initiate ESL as add-on to an existing antiepileptic drug (AED) monotherapy were invited to participate. The study comprised three visits: baseline, and after 3 and 6 months. Data on ESL retention, efficacy, tolerability, safety, and QoL were collected. After 6 months, the retention rate of ESL was 82.2%, and 81.8% of patients reported a reduction of seizure frequency of at least 50%; 39.2% of patients reported seizure freedom at this time. The mean QOLIE-10 score improved from 2.9 (SD ± 0.8) at baseline to 2.1 (SD ± 0.8) after 6 months. 109 adverse events (AEs) were reported in 57 patients (26.0%); the majority were rated as related to ESL by the investigator and led to a discontinuation of ESL in 25 patients (11.4%). Eight patients (3.7%) suffered at least one serious AE. The most frequently reported AEs were dizziness, headache, convulsion, and fatigue. This study shows that ESL was well tolerated and efficacious as add-on therapy to one baseline AED. The use of ESL in patients less refractory than those included in previous clinical trials led to higher responder and seizure freedom rates. No new safety issues were observed. © 2016 Esai Europe Ltd. Acta Neurologica Scandinavica published by John Wiley & Sons Ltd.

To study the efficacy and tolerability of add-on levetiracetam in children and adolescents with refractory epilepsy. In this prospective multi-centre, open-label, add-on study, 33 children aged 4-16 years (median 8.5 years) with epilepsy refractory to at least two antiepileptic drugs were treated with levetiracetam in addition to their present treatment regimen with a follow-up of 26 weeks. The starting dose of 10 mg/kg/day was increased with 2-week steps of 10 mg/kg/day, if necessary, up to a maximum dose of 60 mg/kg/day. Retention rate was 69.7% after 26 weeks on a median levetiracetam dosage of 22 mg/kg/day. Four children dropped-out because levetiracetam was ineffective, four because seizure frequency increased and/or seizures became more severe, and two because they developed aggressive behaviour. Compared to their baseline seizure frequency, 13 children (39.4%) had a >50% seizure reduction 12 weeks after initiation of levetiracetam, and 17 children (51.5%) at 26 weeks. At 26 weeks, nine children (27.3%) had been seizure-free for at least the last 4 weeks, terminal remission ranged from 0 to 187 days (mean 46 days). Levetiracetam was effective in both partial and primary generalized seizures, but had most effect in partial seizures. Most reported side effects were hyperactivity (48.5%), somnolence (36.4%), irritability (33.3%) and aggressive behaviour (27.3%). Severity of most side effects was mild. Five children had a serious adverse event, which all concerned hospital admissions that were not related to levetiracetam use. Levetiracetam proved to be an effective and well-tolerated add-on treatment in this group of children with refractory epilepsy.

Dietary intake is the major bisphenol A (BPA) exposure route in humans, and is a cause of BPA-related adverse effects. The large-scale exposure risk of humans to BPA through dietary sources in Taiwan is less well studied. The aim of this study was to assess the average daily dose (ADD) and hazardous quotient (HQ) of BPA exposure risk from long-term dietary intake of BPA, as well as BPA concentrations in different age-sex groups in Taiwan. We reanalyzed the BPA concentrations of regular daily food sources (rice, poultry, livestock, seafood, protein, fruits, and vegetables) and used a national dietary survey to estimate the contribution of variance to ADDs and potential human health effect for different age-sex groups. This study found that the daily consumption of chicken, pork/beef, and seafood were estimated to be 33.77 (Male)/22.65 (Female), 91.70 (M)/66.35 (F), and 54.15 (M)/40.78 (F) g/day, respectively. The highest BPA ADD was found in the 6-9 years age group (95% CI=0.0006-0.0027 mg/kg-bw/day), whereas the lowest BPA ADD was in the ≥65 years age group (0.0002-0.0020 mg/kg-bw/day). Based on the latest EFSA guidelines (0.004 mg/kg-bw/day), the 97.5 percentile HQ of BPA intake in different age-sex groups in Taiwan posed no risks through dietary intake. However, a combination of multiple exposure routes and long-term exposure in specific populations may be of concern in the future. Copyright © 2015 Elsevier B.V. All rights reserved.

Turpentine is a volatile component of resin, which is an abundant forest resource in Southern China. As one of the most important components, the integrated application of β-pinene has been studied. The broad-spectrum evaluation of β-pinene and its analogues has, therefore, been necessary. In an attempt to expand the scope of agro-activity trials, the preparation and the evaluation of the herbicidal activity of a series of β-pinene analogues against three agricultural herbs were carried out. In accordance with the overall herbicidal activity, it is noteworthy that compounds 6k , 6l , and 6m demonstrated extreme activity with IC 50 values of 0.065, 0.065, and 0.052 mol active ingredients/hectare against E. crus-galli . The preliminary structure-activity relationship (SAR) was analyzed and the compounds with the appropriate volatility and substituent type that had beneficial herbicidal activity were analyzed. Simultaneously, the quantitative structure-activity relationship (QSAR) model was built and the most important structural features were indicated, which was, to a certain extent, in line with the SAR study. The study aimed to study the application of the forest resource turpentine in agriculture as a potential and alternative approach for comprehensive utilization.

Waterborne transmission ofCampylobacter enteritis.

Campylobacter jejuni is an important cause of human diarrheal disease throughout the world and likeSalmonella enteritidis, has a large animal reservoir which includes most of man's domestic animals. Until recently, it has been difficult to trace the chain of transmission from animals to man because of inadequate environmental sampling techniques and means to distinguish strains. Recent improvements in these techniques have made environmental studies more feasible in 2 water-related out-breaks.In 1 study,C. jejuni was found to be an important cause of sporadic, summertime diarrheal disease among hikers in national wilderness areas of Wyoming. In this setting, illness was significantly associated with drinking untreated surface water. SubsequentlyC. jejuni was isolated from surface water, including mountian streams, and from animals in the area. Some of the environmental isolates were serotypically identical to strains isolated from humans.A second study occurred as a result of an outbreak of Campylobacter enteritis in a community in northern Illinois which was epidemiologically associated with the community water system.Campylobacter jejuni was isolated from several surface water sources and from the implicated water system. These studies demonstrate that environmental isolation ofC. jejuni is now possible and may add to our understanding of disease transmission.

Riboswitches are noncoding mRNA segments that can regulate the gene expression via altering their structures in response to specific metabolite binding. We proposed a coarse-grained Gaussian network model (GNM) to examine the unfolding and folding dynamics of adenosine deaminase (add) A-riboswitch upon the adenine dissociation, in which the RNA is modeled by a nucleotide chain with interaction networks formed by connecting adjoining atomic contacts. It was shown that the adenine binding is critical to the folding of the add A-riboswitch while the removal of the ligand can result in drastic increase of the thermodynamic fluctuations especially in the junction regionsmore » between helix domains. Under the assumption that the native contacts with the highest thermodynamic fluctuations break first, the iterative GNM simulations showed that the unfolding process of the adenine-free add A-riboswitch starts with the denature of the terminal helix stem, followed by the loops and junctions involving ligand binding pocket, and then the central helix domains. Despite the simplified coarse-grained modeling, the unfolding dynamics and pathways are shown in close agreement with the results from atomic-level MD simulations and the NMR and single-molecule force spectroscopy experiments. Overall, the study demonstrates a new avenue to investigate the binding and folding dynamics of add A-riboswitch molecule which can be readily extended for other RNA molecules.« less

Porcine mesenchymal stem cells in postnatal muscle have been demonstrated to differentiate into adipocytes. This increases adipocyte number and lipid accumulation, and is thought to be the origin of intramuscular fat. In this study, the effects of myostatin and arginine on adipogenic differentiation in mesenchymal stem cells derived from porcine muscle (pMDSCs) were investigated in vitro. Intracellular triglyceride levels were reduced by exogenous myostatin and increased by arginine supplementation or myostatin antibody (P<0.01). The inhibition of lipid accumulation by myostatin in pMDSCs was alleviated by arginine supplementation (P<0.01). Expression patterns of adipogenic transcription factors showed that exogenous myostatin suppressed PPARγ2 and aP2 expression (P<0.01), while supplemental arginine or myostatin antibody promoted ADD1 expression (P<0.01). Furthermore, compared with the addition of either myostatin protein or antibody alone, ADD1 and PPARδ expression were promoted by the combination of arginine and myostatin (P<0.01), and arginine combined with myostatin antibody promoted the expression of ADD1, PPARδ, C/EBPα, PPARγ2 and LPL in pMDSCs (P<0.05). These results suggest that myostatin inhibits adipogenesis in pMDSCs, and that this can be alleviated by arginine supplementation, at least in part, through promoting ADD1 and PPARδ expression.

The Problem of Confounding in Studies of the Effect of Maternal Drug Use on Pregnancy Outcome

PubMed Central

Källén, Bengt

2012-01-01

In most epidemilogical studies, the problem of confounding adds to the uncertainty in conclusions drawn. This is also true for studies on the effect of maternal drug use on birth defect risks. This paper describes various types of such confounders and discusses methods to identify and adjust for them. Such confounders can be found in maternal characteristics like age, parity, smoking, use of alcohol, and body mass index, subfertility, and previous pregnancies including previous birth of a malformed child, socioeconomy, race/ethnicity, or country of birth. Confounding by concomitant maternal drug use may occur. A geographical or seasonal confounding can exist. In rare instances, infant sex and multiple birth can appear as confounders. The most difficult problem to solve is often confounding by indication. The problem of confounding is less important for congenital malformations than for many other pregnancy outcomes.

This study investigated the association of academic outcomes, romantic relationships, and substance use (tobacco, marijuana, cocaine) with alcohol dependence in a sample of Latino (N = 1,143) college students. Secondary data analysis was conducted on measures of grade point average in college, relationship satisfaction, drug use, and alcohol dependence. Latino college students who reported alcohol dependency had significant relational dissatisfaction and poor academic outcomes. Thus, lower grade point average and relationship dissatisfaction were associated with alcohol dependence. By focusing specifically on a Mexican American population, this study adds important information to current research regarding the commonality and differences across cultural groups regarding drug use and dependence and further clarifies the risk factors associated with substance use and dependency in a population that is vulnerable for at-risk behaviors. This study also offers insight into potential targets of treatment and intervention for this cultural group.

The Study of Complex (Ti, Zr, Cs) Nanopowder Influencing the Effective Ionization Potential of Arc Discharge When Mma Welding

Strength is one of the most important characteristics of a weld joint. Mechanical properties of a weld metal can be improved in a variety of ways. One of the possibilities is to add a nanopowder to the weld metal. Authors of the paper suggest changing the production process of MMA welding electrodes via adding nanopowder Ti, Zr, Cs to electrode components through liquid glass. Theoretical research into the nanopowder influence on the effective ionization potential (Ueff) of welding arc discharge is also necessitated. These measures support arcing stability, improve strength of a weld joint, as the consequence, ensure quality enhancing of a weld joint and the structure on the whole.

Coherent Radiation in Atomic Systems

NASA Astrophysics Data System (ADS)

Sutherland, Robert Tyler

Over the last century, quantum mechanics has dramatically altered our understanding of light and matter. Impressively, exploring the relationship between the two continues to provide important insights into the physics of many-body systems. In this thesis, we add to this still growing field of study. Specifically, we discuss superradiant line-broadening and cooperative dipole-dipole interactions for cold atom clouds in the linear-optics regime. We then discuss how coherent radiation changes both the photon scattering properties and the excitation distribution of atomic arrays. After that, we explore the nature of superradiance in initially inverted clouds of multi-level atoms. Finally, we explore the physics of clouds with degenerate Zeeman ground states, and show that this creates quantum effects that fundamentally change the photon scattering of atomic ensembles.

Alzheimer's disease (AD) is a neurodegenerative disorder that is characterized by cognitive deficits, problems in activities of daily living, and behavioral disturbances. Electroencephalogram (EEG) has been demonstrated as a reliable tool in dementia research and diagnosis. The application of EEG in AD has a wide range of interest. EEG contributes to the differential diagnosis and the prognosis of the disease progression. Additionally such recordings can add important information related to the drug effectiveness. This review is prepared to form a knowledge platform for the project entitled “Cognitive Signal Processing Lab,” which is in progress in Information Technology Institute in Thessaloniki. The team tried to focus on the main research fields of AD via EEG and recent published studies. PMID:24868482

What can economics add to health technology assessment? Please not just another cost-effectiveness analysis!

PubMed

Bridges, John Fp

2006-02-01

Evidence based medicine is not only important for clinical practice, but national governments have embraced it through health technology assessment (HTA). HTA combines data from randomized controlled trials (RCT) and observational studies with an economic component (among other issues). HTA, however, is not taking full advantage of economics. This paper presents five areas in which economics may improve not only HTA, but the RCT methods that underpin it. HTA needs to live up to its original agenda of being a interdisciplinary field and draw methods not just from biostatistics, but from a range of discipline, including economics. By focusing only on cost effectiveness analysis (CEA), however, we go nowhere close to fulfilling this potential.

What Contributes to the (Im)Balanced Division of Family Work Between the Sexes?

Lothaller, Harald; Mikula, Gerold; Schoebi, Dominik

2011-01-01

This study examines a comprehensive set of variables that have been proposed as explaining the imbalance of the division of family work between the sexes. The analyses use survey data of 735 dual-earner couples from Austria, the Netherlands, and Portugal. The results support theoretical explanations referring to time availability, gender ideology, relative resources, and the importance of characteristics of the family system. No support was obtained for the doing-gender perspective. Additional findings suggest that increased consideration of psychological concepts adds to the understanding of why women do more family work than men. The analyses revealed similarities, but also differences between the factors that contribute to the division of household labor and childcare. PMID:22318972

The human ATRX gene encodes hATRX, a chromatin-remodeling protein harboring an helicase/ATPase and ADD domains. The ADD domain has two zinc fingers that bind to histone tails and mediate hATRX binding to chromatin. dAtrx, the putative ATRX homolog in Drosophila melanogaster, has a conserved helicase/ATPase domain but lacks the ADD domain. A bioinformatic search of the Drosophila genome using the human ADD sequence allowed us to identify the CG8290 annotated gene, which encodes three ADD harboring- isoforms generated by alternative splicing. This Drosophila ADD domain is highly similar in structure and in the amino acids which mediate the histone tail contacts to the ADD domain of hATRX as shown by 3D modeling. Very recently the CG8290 annotated gene has been named dadd1. We show through pull-down and CoIP assays that the products of the dadd1 gene interact physically with dAtrxL and HP1a and all of them mainly co-localize in the chromocenter, although euchromatic localization can also be observed through the chromosome arms. We confirm through ChIP analyses that these proteins are present in vivo in the same heterochromatic regions. The three isoforms are expressed throughout development. Flies carrying transheterozygous combinations of the dadd1 and atrx alleles are semi-viable and have different phenotypes including the appearance of melanotic masses. Interestingly, the dAdd1-b and c isoforms have extra domains, such as MADF, which suggest newly acquired functions of these proteins. These results strongly support that, in Drosophila, the atrx gene diverged and that the dadd1-encoded proteins participate with dAtrx in some cellular functions such as heterochromatin maintenance.

Acute aortic dissection (AD) represents a diagnostic conundrum. Validated algorithms are particularly needed to identify patients where AD could be ruled out without aortic imaging. We evaluated the diagnostic accuracy of a strategy combining the aortic dissection detection (ADD) risk score with D-dimer, a sensitive biomarker of AD. Patients from two clinical centers with suspected AD were prospectively enrolled in a registry, from January 2008 to March 2013. The ADD risk score was calculated by retrospective blinded chart review. For D-dimer, a cutoff of 500 ng/ml was applied. AD was diagnosed in 233 of 1035 (22.5%) patients. The ADD risk score was 0 in 322 (31.1%), 1 in 508 (49.1%) and >1 in 205 (19.8%) patients. The sensitivity and the failure rate of D-dimer were 100% and 0% in patients with ADD score 0, versus 97.5% (95% CI 91.4-99.6%) and 4.2% (95% CI 0.7-12.5%) in patients with ADD risk score >1. In patients with ADD risk score ≤ 1, the sensitivity and the failure rate of D-dimer were 98.7% (95% CI 95.3-99.8%) and 0.8% (95% CI 0.1-2.6%). The diagnostic efficiency of D-dimer in patients with ADD risk score 0 and ≤ 1 was 8.9% (95% CI 7.2-10.7%) and 23.6% (95% CI 21.1-26.2%) respectively. In a large cohort of patients with suspected AD, the presence of ADD risk score 0 or ≤ 1 combined with a negative D-dimer accurately and efficiently ruled out AD.
