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.

NASA Adds Leap Second to Master Clock

NASA Image and Video Library

2017-12-08

On Dec. 31, 2016, official clocks around the world will add a leap second just before midnight Coordinated Universal Time — which corresponds to 6:59:59 p.m. EST. NASA missions will also have to make the switch, including the Solar Dynamics Observatory, or SDO, which watches the sun 24/7. Clocks do this to keep in sync with Earth's rotation, which gradually slows down over time. When the dinosaurs roamed Earth, for example, our globe took only 23 hours to make a complete rotation. In space, millisecond accuracy is crucial to understanding how satellites orbit. "SDO moves about 1.9 miles every second," said Dean Pesnell, the project scientist for SDO at NASA's Goddard Space Flight Center in Greenbelt, Maryland. "So does every other object in orbit near SDO. We all have to use the same time to make sure our collision avoidance programs are accurate. So we all add a leap second to the end of 2016, delaying 2017 by one second." The leap second is also key to making sure that SDO is in sync with the Coordinated Universal Time, or UTC, used to label each of its images. SDO has a clock that counts the number of seconds since the beginning of the mission. To convert that count to UTC requires knowing just how many leap seconds have been added to Earth-bound clocks since the mission started. When the spacecraft wants to provide a time in UTC, it calls a software module that takes into consideration both the mission's second count and the number of leap seconds — and then returns a time in UTC.

When does weight matter most?

PubMed

Chen, Alice J

Past empirical work establishes a wage penalty from being overweight. In this paper, I exploit variation in an individual's weight over time to determine the age when weight has the largest impact on labor market outcomes. For white men, controlling for weight at younger ages does not eliminate the effect of older adult weight on wage: being overweight as a young adult only adds an additional penalty to adult wages. However, for white women, what they weigh in their early twenties solely determines the existence of an adult wage penalty. The female early-twenties weight penalty has a persistent effect on wages, and differences in marital characteristics, occupation status, or education cannot explain it. It also is not a proxy for intergenerational unobservables. Copyright © 2011 Elsevier B.V. All rights reserved.

Pharmaceuticals and chemicals produce hemangiosarcomas (HS) in mice, often by nongenotoxic, proliferative mechanisms. A mode-of-action (MOA) for hemangiosarcoma was proposed based on information presented at an international workshop (Cohen et al., Hemangiosarcoma in rodents: Mode-of-action evaluation and human relevance. Toxicol. Sci. 111, 4-18.). Five key elements of the MOA were articulated and included hypoxia, macrophage activation, increased angiogenic growth factors, dysregulated angiogenesis/erythropoiesis, and endothial cell proliferation. The goal of the current study was to add to the weight-of-evidence for the proposed MOA by assessing these key elements with 3 different compounds of varying potency for HS induction: fenretinide (high), troglitazone (intermediate), and elmiron (low). Multiple endpoints, including hypoxia (hyproxyprobe, transcriptomics), endothelial cell (EC) proliferation, and clinical and anatomic pathology, were assessed after 2, 4, and 13-weeks of treatment in B6C3F1 mice. All 3 compounds demonstrated strong evidence for dysregulated erythropoiesis (decrease in RBC and a failure to increase reticulocytes) and macrophage activation (4- to 11-fold increases); this pattern of hematological changes in mice might serve as an early biomarker to evaluate EC proliferation in suspected target organs for potential HS formation. Fenretinide demonstrated all 5 key elements, while troglitazone demonstrated 4 and elmiron demonstrated 3. Transcriptomics provided support for the 5 elements of the MOA, but was not any more sensitive than hypoxyprobe immunohistochemistry for detecting hypoxia. The overall transcriptional evidence for the key elements of the proposed MOA was also consistent with the potency of HS induction. These data, coupled with the previous work with 2-butoxyethanol and pregablin, increase the weight-of-evidence for the proposed MOA for HS formation. © The Author 2017.

In this paper, we investigate the possibility that genetic variation contributes to self-perceived weight status among adolescents and young adults in the U.S. Using samples of identical and fraternal twins across four waves of the National Longitudinal Study of Adolescent to Adult Health (Add Health) study, we calculate heritability estimates for objective body mass index (BMI) that are in line with previous estimates. We also show that perceived weight status is heritable (h(2) ∼ 0.47) and most importantly that this trait continues to be heritable above and beyond objective BMI (h(2) ∼ 0.25). We then demonstrate significant sex differences in the heritability of weight identity across the four waves of the study, where h(2)women = 0.39, 0.35, 0.40, and 0.50 for each wave, respectively, and h(2)men = 0.10, 0.10, 0.23, and 0.03. These results call for a deeper consideration of both identity and gender in genetics research. Copyright © 2016 Elsevier Ltd. All rights reserved.

An information-theoretical perspective on weighted ensemble forecasts

NASA Astrophysics Data System (ADS)

Weijs, Steven V.; van de Giesen, Nick

2013-08-01

This paper presents an information-theoretical method for weighting ensemble forecasts with new information. Weighted ensemble forecasts can be used to adjust the distribution that an existing ensemble of time series represents, without modifying the values in the ensemble itself. The weighting can, for example, add new seasonal forecast information in an existing ensemble of historically measured time series that represents climatic uncertainty. A recent article in this journal compared several methods to determine the weights for the ensemble members and introduced the pdf-ratio method. In this article, a new method, the minimum relative entropy update (MRE-update), is presented. Based on the principle of minimum discrimination information, an extension of the principle of maximum entropy (POME), the method ensures that no more information is added to the ensemble than is present in the forecast. This is achieved by minimizing relative entropy, with the forecast information imposed as constraints. From this same perspective, an information-theoretical view on the various weighting methods is presented. The MRE-update is compared with the existing methods and the parallels with the pdf-ratio method are analysed. The paper provides a new, information-theoretical justification for one version of the pdf-ratio method that turns out to be equivalent to the MRE-update. All other methods result in sets of ensemble weights that, seen from the information-theoretical perspective, add either too little or too much (i.e. fictitious) information to the ensemble.

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.

Considering Patient Diet Preference to Optimize Weight Loss: Design Considerations of a Randomized Trial Investigating the Impact of Choice

A variety of diet approaches achieve moderate weight loss in many individuals. Yet, most diet interventions fail to achieve meaningful weight loss in more than a few individuals, likely due to inadequate adherence to the diet. It is widely conjectured that targeting the diet to an individual's food preferences will enhance adherence, thereby improving weight loss. This article describes the design considerations of a study protocol aimed at testing this hypothesis. The study is a 2-arm randomized trial recruiting 216 medical outpatients with BMI ≥30 kg/m2 followed for 48 weeks. Participants in the experimental arm (Choice) select from two of the most widely studied diets for weight loss, a low-carbohydrate, calorie-unrestricted diet (LCD) or a low-fat, reduced-calorie diet (LFD). The participant's choice is informed by results from a validated food preference questionnaire and a discussion of diet options with trained personnel. Choice participants are given the option to switch to the other diet after three months, if desired. Participants in the Control arm are randomly assigned to follow one of the two diets for the duration of follow-up. The primary outcome is weight assessed every 2-4 weeks for 48 weeks. Secondary outcomes include adherence to diet by food frequency questionnaire and obesity-specific health-related quality of life. If assisting patients to choose their diet enhances adherence and increases weight loss, the results will support the provision of diet options to patients who desire weight loss, and bring us one step closer to remediating the obesity epidemic faced by our healthcare systems.

Impact of carbohydrates on weight regain.

PubMed

Bosy-Westphal, Anja; Müller, Manfred J

2015-07-01

Research on obesity treatment has shifted its focus from weight loss to weight-loss maintenance strategies. The conventional approach of a low-fat diet is challenged by insights from glycemic effects of carbohydrates on body weight regulation. Metabolic and endocrine adaptations to weight loss that contribute to weight regain involve reduced energy expenditure, increased insulin sensitivity, and enhanced orexigenic signals. This review summarizes the impact of carbohydrates on energetic efficiency, partitioning of weight regain as fat and lean mass, and appetite control. Both the amount and frequency of postprandial glycemia add to body weight regulation after weight loss and strengthen the concept of glycemic index and glycemic load. In addition, dietary fiber and slowly or poorly absorbable functional sugars modify gastrointestinal peptides involved in appetite and metabolic regulation and exert prebiotic effects. Current evidence suggests that a low-glycemic load diet with a preference for low-glycemic index foods and integration of slowly digestible, poorly absorbable carbohydrates may improve weight-loss maintenance. Future studies should investigate the health benefits of low glycemic functional sweeteners (e.g., isomaltulose and tagatose).

In this post hoc analysis of the EDGE study, we assessed the effectiveness and safety of vildagliptin versus other oral antidiabetes drugs (OADs) as add-on to first-line sulphonylurea (SU) therapy in patients who did not receive metformin in a real-life setting. The primary endpoint was odds of achieving an HbA1c reduction of >0.3% without tolerability issues. Secondary endpoint was odds of achieving HbA1c <7.0% without hypoglycaemia or weight gain. Changes in HbA1c, body weight; and safety were also assessed. 2936 patients received vildagliptin and 820 received comparator OADs (any α-GI, TZD, glinide) as add-on to first-line SU therapy. Overall, the mean age, disease duration, HbA1c, and BMI at baseline were 57.1 years, 6.3 years, 8.5%, and 27.7kg/m 2 , respectively. The odds ratios for achieving primary and secondary endpoints were 1.6 (95% CI: 1.36, 1.86; p<0.0001) and 1.8 (1.45, 2.21; p<0.0001), respectively, in favour of vildagliptin. The between-treatment differences (vildagliptin vs. comparator OAD) for the mean change in HbA1c and body weight were -0.2±0.04% (p<0.0001) and -0.8±0.16kg (p<0.0001), respectively. Overall, the incidence of adverse events was low (vildagliptin, 7% vs. comparator, 8.2%) in both groups. Similar results were observed in a subset of patients enrolled from India and patients who received TZDs as a comparator OAD. Under real-life settings, vildagliptin as add-on to SU monotherapy showed better glycaemic response without tolerability issues compared with other OADs.

We performed a retrospective study in patients with poorly controlled epilepsy treated with add-on lacosamide (LCM) to investigate the relationship of LCM-related adverse events with LCM serum concentration and weight-dependent dosage. We collected serum concentrations, weight-related dosages, and occurrences of the seven most frequent adverse events according to the randomized double-blind, placebo-controlled trials. Seventy of 131 patients could be sufficiently evaluated. LCM serum concentrations and weight-related dosages in patients with and without typical adverse events did not differ significantly. Closer analysis of the data suggested that dizziness as the leading adverse event occurred significantly more often if LCM was combined with classic sodium channel blockers. There was a significant correlation between LCM serum concentrations and co-medication, so there is still evidence for dependent variables that might have a relevant impact in individual cases. However, our data do not allow definition of a safety range for LCM. Copyright © 2011 Elsevier Inc. All rights reserved.

Abstract Background: Oral contraceptive (OC) use seems to have little effect on weight change in normal weight women. Most previous studies have excluded obese women, so the effect of OC use on weight change in obese women is unknown. Methods: This analysis evaluates weight and body composition change with OC use among obese (body mass index [BMI] 30.0–39.9) and normal weight (BMI 19.0–24.9) women who were randomly assigned to two OC doses: 20 μg ethinyl estradiol (EE) and 100 μg levonorgestrel (LNG) OCs or 30 μg EE and 150 μg LNG OCs. Follow-up occurred after three to four OC cycles. Weight and body composition were measured at baseline and at follow-up using a bioelectrical impedance analyzer. Results: Among 150 women (54 obese and 96 normal weight) who used OCs for 3 to 4 months, there were no clinically or statistically significant weight or body composition changes in the overall group or by BMI or OC formulation group. Conclusions: These findings add to evidence that EE/LNG OCs are not associated with short term weight or body composition change for normal weight women and suggest that OCs are also are not associated with short term weight or body composition change in obese women.

Medical, nutritional, and dental considerations in children with low birth weight.

It is estimated that 8 to 26 percent of infants are born with low birth weight (LBW) worldwide. These children are at risk for medical problems in childhood and adulthood and often have poor oral health. The influence of fetal growth on birth weight and its relevance to childhood growth and future adult health is controversial. Evidence now indicates that the postnatal period is a critical time when nutrition may predispose the child to lifelong metabolic disturbance and obesity. Given the lack of consensus on optimum infant nutrition for LBW, premature, and small-for-gestational-age infants, many such infants may be suboptimally managed. This may result in rapid postnatal weight gain and ongoing health problems. The purpose of this review was to summarize medical terminology and issues related to fetal growth, morbidity associated with being born low birth weight, premature, or small for gestational age, and the importance of appropriate nutrition in such infants. Pediatric dentists can play an important role in supporting healthy feeding practices and improving long-term health in these children. Early integrated medical and dental care should be encouraged for all children with low birth weight.

Add-on unidirectional elastic metamaterial plate cloak

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.

The mode of action human relevance (MOA/HR) framework increases transparency in systematically considering data on MOA for end (adverse) effects and their relevance to humans. This framework continues to evolve as experience increases in its application. Though the MOA/HR framework is not designed to address the question of “how much information is enough” to support a hypothesized MOA in animals or its relevance to humans, its organizing construct has potential value in considering relative weight of evidence (WOE) among different cases and hypothesized MOA(s). This context is explored based on MOA analyses in published assessments to illustrate the relative extent of supporting data and their implications for dose–response analysis and involved comparisons for chemical assessments on trichloropropane, and carbon tetrachloride with several hypothesized MOA(s) for cancer. The WOE for each hypothesized MOA was summarized in narrative tables based on comparison and contrast of the extent and nature of the supporting database versus potentially inconsistent or missing information. The comparison was based on evolved Bradford Hill considerations rank ordered to reflect their relative contribution to WOE determinations of MOA taking into account increasing experience in their application internationally. This clarification of considerations for WOE determinations as a basis for comparative analysis is anticipated to contribute to increasing consistency in the application of MOA/HR analysis and potentially, transparency in separating science judgment from public policy considerations in regulatory risk assessment.

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.

Weight gain represents a frequent side effect of antipsychotic drug treatment. The current trial investigated the effect of add-on treatment with sibutramine in schizophrenia outpatients who had gained more than 7% of weight during the course of treatment. This 24-week placebo-controlled study evaluated the effects of sibutramine added to ongoing antipsychotic treatment. Weight, waist-hip ratio, BMI, blood pressure/pulse and ECG were monitored regularly. In addition, several laboratory tests were performed. Psychopathological symptoms and side effects were assessed frequently. Fifteen patients were assigned randomly to add-on treatment with sibutramine 10 mg or placebo. The two groups did not differ in weight, sociodemographic, or clinical data. Eleven patients were considered for statistical analysis. Significant weight loss was observed in the sibutramine group (mean = -6.1 kg), whereas patients on placebo experienced a mean weight gain of 1.9 kg. A reduction in HbA1c was apparent in the sibutramine but not in the placebo group. No significant between-group differences were found in changes in psychopathology or drug safety. This pilot trial suggests that adjunctive treatment with sibutramine may be safe and effective in schizophrenic patients with antipsychotic-induced weight gain.

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).

Tungsten fiber reinforced superalloy composites (TFRS) are intended for use in high temperature turbine components. Current turbine component design methodology is based on applying the experience, sometimes semiempirical, gained from over 30 years of superalloy component design. Current composite component design capability is generally limited to the methodology for low temperature resin matrix composites. Often the tendency is to treat TFRS as just another superalloy or low temperature composite. However, TFRS behavior is significantly different than that of superalloys, and the high environment adds consideration not common in low temperature composite component design. The methodology used for preliminary design of TFRS components are described. Considerations unique to TFRS are emphasized.

A method of estimating the load-bearing fuselage weight and wing weight of transport aircraft based on fundamental structural principles has been developed. This method of weight estimation represents a compromise between the rapid assessment of component weight using empirical methods based on actual weights of existing aircraft, and detailed, but time-consuming, analysis using the finite element method. The method was applied to eight existing subsonic transports for validation and correlation. Integration of the resulting computer program, PDCYL, has been made into the weights-calculating module of the AirCraft SYNThesis (ACSYNT) computer program. ACSYNT has traditionally used only empirical weight estimation methods; PDCYL adds to ACSYNT a rapid, accurate means of assessing the fuselage and wing weights of unconventional aircraft. PDCYL also allows flexibility in the choice of structural concept, as well as a direct means of determining the impact of advanced materials on structural weight. Using statistical analysis techniques, relations between the load-bearing fuselage and wing weights calculated by PDCYL and corresponding actual weights were determined.

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.

Frequency-Weighting Filter Selection, for H2 Control of Microgravity Isolation Systems: A Consideration of the "Implicit Frequency Weighting" Problem

NASA Technical Reports Server (NTRS)

Hampton, Roy David; Whorton, Mark S.

1999-01-01

Many space-science experiments need an active isolation system to provide them with the requisite microgravity environment. The isolation systems planned for use with the International Space Station (ISS) have been appropriately modeled using relative position, relative velocity, and acceleration states. In theory, frequency-weighting design filters can be applied to these state-space models, in order to develop optimal H2 or mixed-norm controllers with desired stability and performance characteristics. In practice, however, since there is a kinematic relationship among the various states, any frequency weighting applied to one state will implicitly weight other states. These implicit frequency-weighting effects must be considered, for intelligent frequency-weighting filter assignment. This paper suggests a rational approach to the assignment of frequency-weighting design filters, in the presence of the kinematic coupling among states that exists in the microgravity vibration isolation problem.

Stiripentol add-on therapy for focal refractory epilepsy.

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

Clinical laboratories frequently receive orders to perform additional tests on existing specimens ('add-ons'). Previous studies have examined add-on ordering patterns over short periods of time. The objective of this study was to analyze add-on ordering patterns over an extended time period. We also analyzed the impact of a robotic specimen archival/retrieval system on add-on testing procedure and manual effort. In this retrospective study at an academic medical center, electronic health records from were searched to obtain all add-on orders that were placed in the time period of May 2, 2009 to December 31, 2014. During the time period of retrospective study, 880,359 add-on tests were ordered on 96,244 different patients. Add-on testing comprised 3.3 % of total test volumes. There were 443,411 unique ordering instances, leading to an average of 1.99 add-on tests per instance. Some patients had multiple episodes of add-on test orders at different points in time, leading to an average of 9.15 add-on tests per patient. The majority of add-on orders were for chemistry tests (78.8 % of total add-ons) with the next most frequent being hematology and coagulation tests (11.2 % of total add-ons). Inpatient orders accounted for 66.8 % of total add-on orders, while the emergency department and outpatient clinics had 14.8 % and 18.4 % of total add-on orders, respectively. The majority of add-ons were placed within 8 hours (87.3 %) and nearly all by 24 hours (96.8 %). Nearly 100 % of add-on orders within the emergency department were placed within 8 hours. The introduction of a robotic specimen archival/retrieval unit saved an average of 2.75 minutes of laboratory staff manual time per unique add-on order. This translates to 24.1 hours/day less manual effort in dealing with add-on orders. Our study reflects the previous literature in showing that add-on orders significantly impact the workload of the clinical laboratory. The majority of add-on orders are clinical chemistry

Systematic consideration of scientific support is a critical element in developing and, ultimately, using adverse outcome pathways (AOPs) for various regulatory applications. Though weight of evidence (WoE) analysis has been proposed as a basis for assessment of the maturity and level of confidence in an AOP, methodologies and tools are still being formalized. The Organization for Economic Co-operation and Development (OECD) Users' Handbook Supplement to the Guidance Document for Developing and Assessing AOPs (OECD 2014a; hereafter referred to as the OECD AOP Handbook) provides tailored Bradford-Hill (BH) considerations for systematic assessment of confidence in a given AOP. These considerations include (1) biological plausibility and (2) empirical support (dose-response, temporality, and incidence) for Key Event Relationships (KERs), and (3) essentiality of key events (KEs). Here, we test the application of these tailored BH considerations and the guidance outlined in the OECD AOP Handbook using a number of case examples to increase experience in more transparently documenting rationales for assigned levels of confidence to KEs and KERs, and to promote consistency in evaluation within and across AOPs. The major lessons learned from experience are documented, and taken together with the case examples, should contribute to better common understanding of the nature and form of documentation required to increase confidence in the application of AOPs for specific uses. Based on the tailored BH considerations and defining questions, a prototype quantitative model for assessing the WoE of an AOP using tools of multi-criteria decision analysis (MCDA) is described. The applicability of the approach is also demonstrated using the case example aromatase inhibition leading to reproductive dysfunction in fish. Following the acquisition of additional experience in the development and assessment of AOPs, further refinement of parameterization of the model through expert

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.

The development of autonomous Micro Aerial Vehicles (MAVs) is significantly constrained by their size, weight and power consumption. In this paper, we explore the energetics of quadrotor platforms and study the scaling of mass, inertia, lift and drag with their characteristic length. The effects of length scale on masses and inertias associated with various components are also investigated. Additionally, a study of Lithium Polymer battery performance is presented in terms of specific power and specific energy. Finally, we describe the power and energy consumption for different quadrotors and explore the dependence on size and mass for static hover tests as well as representative maneuvers.

Changes in weight status from adolescence to adulthood may be associated with varying social, vocational, economic, and educational outcomes, which may differ by sex. We studied whether there are differences in adult outcomes by sex for different weight status changes in the transition to adulthood. Using data from the National Longitudinal Study of Adolescent Health, participants were categorized by weight status from adolescence into adulthood. We examined self-reported outcomes in adulthood for living with parents, being married, being a parent, employment, receipt of public assistance, income, and college graduation by weight groupings (healthy-healthy, healthy-overweight/obese, overweight/obese-overweight/obese, overweight/obese-healthy). The effect of changes in weight status on the adult outcomes was modeled, controlling for sex, age, parental education, and race/ethnicity. There were differences by sex for many of the self-reported outcomes, especially educational and economic outcomes. Female subjects who became overweight/obese between adolescence and adulthood or remained so had worse economic and educational findings as adults compared to male subjects. Overall, for female subjects, becoming and remaining overweight/obese was associated with worse outcomes, while for male subjects, adolescent obesity was more important than isolated adult obesity. The relationship between obesity and life situations may be more negative for female subjects in the transition to adulthood. The findings emphasize that adolescent obesity, and not just obesity isolated in adulthood, is important for characteristics achieved in adulthood. Copyright © 2014 Academic Pediatric Association.

Clinical outcome may differ owing to the distinct pharmacological characteristics of insulin sensitizers and insulin. This study was performed to compare the metabolic and renal function changes with add-on pioglitazone treatment versus basal insulin in patients with type 2 diabetes mellitus (DM) in whom sulfonylurea and metformin regimens failed. Patients who were consecutively managed in the diabetes comprehensive program with add-on pioglitazone or detemir/glargine treatment for at least 2 years following sulfonylurea and metformin treatment failure were included. A total of 1002 patients were enrolled (pioglitazone: 559, detemir: 264, glargine: 179). After propensity score matching, there were 105 patients with matchable baseline characteristics in each group. After a mean of 3.5 years of follow-up, the pioglitazone group showed a greater HbA1c reduction than the detemir group and the glargine group. Despite patients in all three groups exhibiting significant body weight gain, those in the pioglitazone group and the glargine group showed greater body weight increases than the patients in the detemir group (2.1, 1.6 and 0.8 kg, respectively, p < 0.05). Interestingly, Cox regression analysis indicated that patients under detemir or glargine treatment had a higher probability of CKD progression as compared with the pioglitazone group, with hazard ratios of 2.63 (95% CI 1.79-3.88) and 3.13 (95% CI 2.01-4.87), respectively. Our study first showed that treatment with both pioglitazone and basal insulin improved glycemic control, while only pioglitazone treatment was observed to be advantageous in terms of preserving renal function when used as an add-on therapy for patients with type 2 DM in whom sulfonylurea and metformin regimens failed.

To investigate changes in body weight trajectories after the addition of individual sulphonylureas (SUs) to metformin in patients with type 2 diabetes. We conducted a retrospective observational cohort study, in a primary care setting in the Netherlands. Patients aged ≥18 years with type 2 diabetes who were included in the ZODIAC cohort between 1998 and 2012 and who received metformin monotherapy at inclusion (n = 29 195), and had used metformin as monotherapy for at least 1 year before receiving dual therapy through the addition of an SU for at least 1 year were eligible for inclusion. The primary outcome was within-drug yearly change in body weight after receiving add-on therapy with individual SUs during 5 years of follow-up. The secondary outcome was within-drug yearly change in glycated haemoglobin (HbA1c). Annual changes in weight and HbA1c were estimated with linear mixed models, adjusted for age, gender and diabetes duration. A total of 2958 patients were included. No significant weight changes were observed within and between any of the individual SUs after treatment intensification (p = 0.24). In addition, no significant difference in weight between the add-on therapy combinations was observed (p = 0.26). The average HbA1c the year before intensification was 7.2% (55 mmol/mol) and dropped below 7.0% (53 mmol/mol) the year after. In patients with type 2 diabetes treated in primary care, strict glycaemic control can be maintained with SUs used as add-on therapy to metformin, without the offset of relevant weight changes. © 2016 The Authors.

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.

Postcessation weight gain concern as a barrier to smoking cessation: Assessment considerations and future directions.

PubMed

Germeroth, Lisa J; Levine, Michele D

2018-01-01

Concern about postcessation weight gain may be one potential barrier to quitting smoking. In this 'mini-review' of recent literature, we summarize findings on the relationship between postcessation weight gain concern and smoking cessation, and evaluate varied use of postcessation weight gain concern assessments and potential moderators of the postcessation weight gain concern-cessation association. We conducted a search using the terms "smoking" OR "smoking cessation" AND "weight concern" for articles published between January 1, 2011 and December 31, 2016. We identified 17 studies assessing postcessation weight gain concern, seven of which evaluated the postcessation weight gain concern-cessation association. The relationship between postcessation weight gain concern and smoking cessation was mixed. Recent studies varied in their assessments of postcessation weight gain concern, many of which were not validated and assessed correlates of this construct. Studies varied in their adjustment of demographic (e.g., sex), smoking-specific (e.g., smoking level), and weight-specific (e.g., body mass index) variables. The use of non-validated assessments and variability in testing covariates/moderators may contribute to conflicting results regarding the postcessation weight gain concern-cessation relationship. We recommend validating an assessment of postcessation weight gain concern, maintaining vigilance in testing and reporting covariates/moderators, and investigating trajectories of this construct over time and by smoking status to inform future assessment and intervention efforts.

MIT-Skywalker: considerations on the Design of a Body Weight Support System.

PubMed

Gonçalves, Rogério Sales; Krebs, Hermano Igo

2017-09-06

To provide body weight support during walking and balance training, one can employ two distinct embodiments: support through a harness hanging from an overhead system or support through a saddle/seat type. This paper presents a comparison of these two approaches. Ultimately, this comparison determined our selection of the body weight support system employed in the MIT-Skywalker, a robotic device developed for the rehabilitation/habilitation of gait and balance after a neurological injury. Here we will summarize our results with eight healthy subjects walking on the treadmill without any support, with 30% unloading supported by a harness hanging from an overhead system, and with a saddle/seat-like support system. We compared the center of mass as well as vertical and mediolateral trunk displacements across different walking speeds and support. The bicycle/saddle system had the highest values for the mediolateral inclination, while the overhead harness body weight support showed the lowest values at all speeds. The differences were statistically significant. We selected the bicycle/saddle system for the MIT-Skywalker. It allows faster don-and-doff, better centers the patient to the split treadmill, and allows all forms of training. The overhead harness body weight support might be adequate for rhythmic walking training but limits any potential for balance training.

To compare efficacy and safety of dapagliflozin ± saxagliptin with glimepiride as add-on to metformin in patients with type 2 diabetes. This 52-week, multicenter, double-blind, active-controlled study (NCT02471404) randomized (1:1:1) patients (n=939; HbA 1C 7.5-10.5%) on metformin monotherapy (≥1500 mg/day) to add-on dapagliflozin 10 mg, dapagliflozin 10 mg plus saxagliptin 5 mg, or glimepiride 1-6 mg (titrated). The primary efficacy end point was change in HbA 1C from baseline to week 52. Baseline mean age, diabetes duration and HbA 1C were 58.4 years, 7.0 years and 8.3%, respectively. Adjusted mean HbA 1C change from baseline was -1.20% with dapagliflozin plus saxagliptin and -0.82% with dapagliflozin, vs. -0.99% with glimepiride (mean dose at week 52: 4.6 mg). Changes in body weight (-3.2 kg and -3.5 k vs +1.8 kg) and systolic blood pressure (SBP; -6.4 mmHg and -5.6 mmHg vs -1.6 mmHg) were significantly greater with dapagliflozin plus saxagliptin and dapagliflozin vs glimepiride; FPG decreased significantly with dapagliflozin plus saxagliptin vs glimepiride (-2.1 mmol/L vs -1.5 mmol/L) and was similar for dapagliflozin (-1.6 mmol/L) vs glimepiride. Confirmed hypoglycemia incidence was lower with dapagliflozin regimens than with glimepiride (0 and 1 vs 13 patients) and fewer patients required rescue. Genital infections were more frequent with dapagliflozin; other AE profiles were similar. Dapagliflozin, saxagliptin and metformin improved glycemic control compared with glimepiride plus metformin; add-on of dapagliflozin alone showed similar efficacy to glimepiride. Both dapagliflozin regimens decreased body weight and SBP, with lower hypoglycemia incidence compared with glimepiride. This article is protected by copyright. All rights reserved.

2017-01-01

Animal models are vital in understanding the transmission and pathogenesis of infectious organisms and the host immune response to infection. In addition, animal models are essential in vaccine and therapeutic drug development and testing. Prior to selecting an animal model to use when studying an infectious agent, the scientific team must determine that sufficient in vitro and ex vivo data are available to justify performing research in an animal model, that ethical considerations are addressed, and that the data generated from animal work will add useful information to the body of scientific knowledge. Once it is established that an animal should be used, the questions become ‘Which animal model is most suitable?’ and ‘Which experimental design issues should be considered?’ The answers to these questions take into account numerous factors, including scientific, practical, welfare, and regulatory considerations, which are the focus of this article.

Previous studies suggest that presurgical psychopathology accounts for some of the variance in suboptimal weight loss outcomes among Roux-en-Y gastric bypass (RYGB) patients, but research has been equivocal. The present study seeks to extend the past literature by examining associations between presurgical scale scores on the broadband Minnesota Multiphasic Personality Inventory-2-Restructured Form (MMPI-2-RF) and suboptimal weight loss and poor adherence to follow-up 1 year postoperatively after accounting for several methodologic considerations. Cleveland Clinic Bariatric and Metabolic Institute, Cleveland, Ohio, USA. The sample consisted of 498 RYGB patients, who produced a valid presurgical MMPI-2-RF protocol at program intake. The sample was primarily female (72.9%), Caucasian (64.9%), and middle-aged (mean = 46.4 years old; standard deviation [SD] = 11.6). The mean presurgical body mass index (BMI) was 47.4 kg/m(2) (SD = 8.2) and mean percent weight loss (%WL) at 1 year postoperatively was 31.18 %WL (SD = 8.44). As expected, scales from the Behavioral/Externalizing Dysfunction (BXD) domain of the MMPI-2-RF were associated with worse weight loss outcomes and poor adherence to follow-up, particularly after accounting for range restriction due to underreporting. Individuals producing elevated scores on these scales were at greater risk for achieving suboptimal weight loss (<50% excess weight loss) and not following up with their appointment compared with those who scored below cut-offs. Patients who are more likely to engage in undercontrolled behavior (e.g., poor impulse control), as indicated by presurgical MMPI-2-RF findings, are at greater risk for suboptimal weight loss and poor adherence to follow-up following RYGB. Objective psychological assessments should also be conducted postoperatively to ensure that intervention is administered in a timely manner. Future research in the area of presurgical psychological screening should consider the impact of

Birth weight and cognitive development in adolescence: causal relationship or social selection?

PubMed

Gorman, Bridget K

2002-01-01

Using data from the National Longitudinal Survey of Adolescent Health (Add Health), I investigate the relationship between birth weight and cognitive development among adolescents aged 12-17. Initial OLS regression models reveal a significant, positive relationship between low birth weight and verbal ability. Controlling for demographic, socioeconomic, and other adolescent characteristics modifies, but does not eliminate, this relationship. Additional models that stratify the sample by parental education illustrate the greater importance of other family and adolescent characteristics for cognitive development in adolescence, and a diminished role of birth weight. In the final section of the paper, fixed effects models of non-twin full siblings indicate no significant association between birth weight and verbal ability, suggesting that traditional cross-sectional models overstate the influence of birth weight for cognitive development in adolescence.

Purpose: Current research indicates that specific parenting styles are associated with adolescent overweight, dietary intake and physical activity, but the majority of research has been cross-sectional making it difficult to determine the temporal order of these associations. The current study adds to the previous research by examining 5-year longitudinal associations between parenting style and adolescent weight and weight-related behaviors. Methods: Data from Project EAT, a population-based study with adolescents from diverse ethic and socioeconomic backgrounds were used. Adolescents (N = 2516) from 31 Minnesota schools completed in-class assessments in 1999 (Time 1) and mailed surveys in 2004 (Time 2). Multiple linear regression models were used to predict mean levels of adolescent outcomes at Time 2 from parenting style at Time 1. Results: Time 1 maternal authoritative parenting style predicted lower BMI in adolescent sons and daughters at Time 2. Time 1 paternal permissive parenting style predicted more fruits and vegetables intake in daughters at Time 2. Significant associations were not found between parenting style and adolescent physical activity. Conclusions: Findings suggest that authoritative parenting style may play a protective role related to adolescent overweight and that the dimension of warmth/caring in the parent/adolescent relationship may be important in relation to female adolescent healthy dietary intake. Further exploration of opposite sex parent/adolescent dyad patterns related to parenting style and adolescent weight and weight-related behaviors is warranted. PMID:20307821

Epilepsy is a common neurologic disorder, affecting approximately 50 million people worldwide; nearly a third of these people are not well controlled by a single antiepileptic drug and usually require treatment with a combination of two or more antiepileptic drugs. In recent years, many newer antiepileptic drugs have been investigated as add-on therapy for partial epilepsy; losigamone is one of these drugs and is the focus of this systematic review. To investigate the efficacy and safety of losigamone when used as an add-on therapy for partial epilepsy. We searched the Cochrane Epilepsy Group Specialized Register (1 May 2012), the Cochrane Central Register of Controlled Trials (CENTRAL Issue 4 of 12, The Cochrane Library, 2012) and MEDLINE (1 May 2012). We searched trials registers and contacted the manufacturer of losigamone and authors of included studies for additional information. There were no language restrictions. Randomized controlled add-on trials comparing losigamone with placebo for partial epilepsy. Two review authors independently assessed trial quality and extracted data. The primary outcomes were 50% or greater reduction in seizure frequency and seizure freedom; the secondary outcomes were treatment withdrawal and adverse events. Results are presented as risk ratios (RR) with 95% confidence intervals (CIs) or 99% CIs (for the individual listed adverse events to make an allowance for multiple testing). Two trials involving a total of 467 patients were eligible for inclusion. Both trials assessed losigamone 1200 or 1500 mg/d as an add-on therapy for partial epilepsy. One trial was assessed as being of good methodologic quality while the other was of uncertain quality. For the efficacy outcomes, results did show patients taking losigamone were significantly more likely to achieve a 50% or greater reduction in seizure frequency (RR 1.75; 95% CI 1.14 to 2.72), but associated with a significant increase of treatment withdrawal when compared with those

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.

Regulatory role of glycogen synthase kinase 3 for transcriptional activity of ADD1/SREBP1c.

Adipocyte determination- and differentiation-dependent factor 1 (ADD1) plays important roles in lipid metabolism and insulin-dependent gene expression. Because insulin stimulates carbohydrate and lipid synthesis, it would be important to decipher how the transcriptional activity of ADD1/SREBP1c is regulated in the insulin signaling pathway. In this study, we demonstrated that glycogen synthase kinase (GSK)-3 negatively regulates the transcriptional activity of ADD1/SREBP1c. GSK3 inhibitors enhanced a transcriptional activity of ADD1/SREBP1c and expression of ADD1/SREBP1c target genes including fatty acid synthase (FAS), acetyl-CoA carboxylase 1 (ACC1), and steroyl-CoA desaturase 1 (SCD1) in adipocytes and hepatocytes. In contrast, overexpression of GSK3beta down-regulated the transcriptional activity of ADD1/SREBP1c. GSK3 inhibitor-mediated ADD1/SREBP1c target gene activation did not require de novo protein synthesis, implying that GSK3 might affect transcriptional activity of ADD1/SREBP1c at the level of post-translational modification. Additionally, we demonstrated that GSK3 efficiently phosphorylated ADD1/SREBP1c in vitro and in vivo. Therefore, these data suggest that GSK3 inactivation is crucial to confer stimulated transcriptional activity of ADD1/SREBP1c for insulin-dependent gene expression, which would coordinate lipid and glucose metabolism.

Vildagliptin is a dipeptidyl peptidase-4 inhibitor commonly used as a dual oral agent with metformin, thiazolidinediones, or sulfonylurea for the treatment of type 2 diabetes mellitus (T2DM). The efficacy of dual therapy with vildagliptin and metformin has been established in randomized controlled trials, but there is little evidence from observational studies. The aims of the present study were to evaluate the effectiveness of vildagliptin as an add-on therapy to metformin in reducing HbA1c and its affects on body weight and blood lipids in a real-life setting. Included in the present retrospective cohort were T2DM patients (n = 345) who were uncontrolled on metformin monotherapy and intensified treatment with vildagliptin. The efficacy of at least 90 days of dual therapy with vildagliptin and metformin in reducing HbA1c levels, as well as changes in blood lipids and body weight, were evaluated. After 180 days (range 90-365 days) from the index date with a mean daily dose of 92 mg vildagliptin, HbA1c was significantly (P < 0.001) reduced by an average of 0.9% (95% confidence interval -1.0%, -0.7%). The absolute reduction in HbA1c was positively associated with baseline HbA1c levels. In addition to HbA1c, a modest but significant (P < 0.05) decrement was also calculated in the patients' body weight and blood lipids. The present analysis of real-world data corroborates the results of previous randomized controlled trials indicating that add-on therapy with vildagliptin in uncontrolled patients on metformin monotherapy is associated with a significant improvement in the control of HbA1c. © 2017 Ruijin Hospital, Shanghai Jiaotong University School of Medicine and John Wiley & Sons Australia, Ltd.

To compare the efficacy and safety of liraglutide versus lixisenatide as add-on to metformin in patients with type 2 diabetes not achieving adequate glycemic control on metformin alone. In this 26-week, randomized, parallel-group, open-label trial, 404 patients were randomized 1:1 to liraglutide 1.8 mg or lixisenatide 20 µg as add-on to metformin. Liraglutide was administered once daily at any time of the day. Lixisenatide was administered once daily within 1 h prior to the morning or evening meal. At week 26, liraglutide reduced HbA1c (primary end point) more than lixisenatide (estimated treatment difference -0.62% [95% CI -0.8; -0.4]; P < 0.0001), with more patients reaching HbA1c <7% (53 mmol/mol) and ≤6.5% (48 mmol/mol) versus lixisenatide (74.2% and 54.6% for liraglutide vs. 45.5% and 26.2% for lixisenatide; P < 0.0001 for both). Liraglutide reduced fasting plasma glucose more than lixisenatide (estimated treatment difference -1.15 mmol/L [95% CI -1.5; -0.8]; P < 0.0001). Liraglutide provided greater reduction in mean 9-point self-measured plasma glucose (P < 0.0001). However, postprandial glucose increments were smaller with lixisenatide for the meal directly after injection compared with liraglutide (P < 0.05), with no differences between treatments across all meals. Both drugs promoted similar body weight decrease (-4.3 kg for liraglutide, -3.7 kg for lixisenatide; P = 0.23). The most common adverse events in both groups were gastrointestinal disorders. Greater increases in pulse, lipase, and amylase were observed with liraglutide. Hypoglycemic episodes were rare and similar between the two treatments. At the dose levels studied, liraglutide was more effective than lixisenatide as add-on to metformin in improving glycemic control. Body weight reductions were similar. Both treatments were well tolerated, with low risk of hypoglycemia and similar gastrointestinal adverse event profiles. © 2016 by the American Diabetes Association.

Loci-CHEM to be applied to flow velocities where surface radiation due to heating from compression and friction becomes significant. The module adds a radiation equilibrium boundary condition to the computational fluid dynamics (CFD) code to produce accurate results. The module expanded the upper limit for accurate CFD solutions of Loci-CHEM from Mach 4 to Mach 10 based on Space Shuttle Orbiter Re-Entry trajectories. Loci-CHEM already has a very promising architecture and performance, but absence of radiation equilibrium boundary condition limited the application of Loci-CHEM to below Mach 4. The immediate advantage of the add-on module is that it allows Loci-CHEM to work with supersonic flows up to Mach 10. This transformed Loci-CHEM from a rocket engine- heritage CFD code with general subsonic and low-supersonic applications, to an aeroheating code with hypersonic applications. The follow-on advantage of the module is that it is a building block for additional add-on modules that will solve for the heating generated at Mach numbers higher than 10.

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

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.

In order to examine the association between pre-pregnancy leisure time physical activities and gestational weight gain, postpartum weight gain and birth weight, we analysed prospectively collected data from 1827 women with singleton term pregnancies. Women were categorised in groups of sedentary women, light exercisers, moderate exercisers and competitive athletes. The results showed that sedentary women on average gained 14.1 kg during pregnancy, whereas light exercisers gained 13.7 kg, moderate exercisers gained 14.3 kg and competitive athletes 16.1 kg. Competitive athletes had an increased risk of having a gestational weight gain above Institute of Medicine (IOM) recommendations with an odds ratio of 2.60 (1.32-5.15) compared to light exercisers. However, birth weight and one year postpartum weight was similar for all four groups. Thus, although competitive athletes gain more weight than recommended during pregnancy, this may not affect birth weight or postpartum weight. Impact statement What is already known on this subjectPrevious studies have found that increased pre-pregnancy physical activity is associated with lower gestational weight gain during the last trimester, but showed no association between the pre-pregnancy level of physical activity and mean birth weight. What the results of this study addWe found that women classified as competitive exercisers had a 2.6-fold increased risk of gaining more weight than recommended compared to light exercisers. Nearly 6 out of 10 women among the competitive exercisers gained more weight than recommended by IOM. Surprisingly, this did not appear to increase birth weight or post-partum weight gain, but other adverse effects cannot be excluded. What the implications are of these findings for clinical practice and/or further researchIn the clinical practice it may be relevant to focus on and advise pre-pregnancy competitive exercisers in order to prevent excessive gestational weight gain.

Mode of action human relevance (species concordance) framework: Evolution of the Bradford Hill considerations and comparative analysis of weight of evidence.

The mode of action human relevance (MOA/HR) framework increases transparency in systematically considering data on MOA for end (adverse) effects and their relevance to humans. This framework continues to evolve as experience increases in its application. Though the MOA/HR framework is not designed to address the question of "how much information is enough" to support a hypothesized MOA in animals or its relevance to humans, its organizing construct has potential value in considering relative weight of evidence (WOE) among different cases and hypothesized MOA(s). This context is explored based on MOA analyses in published assessments to illustrate the relative extent of supporting data and their implications for dose-response analysis and involved comparisons for chemical assessments on trichloropropane, and carbon tetrachloride with several hypothesized MOA(s) for cancer. The WOE for each hypothesized MOA was summarized in narrative tables based on comparison and contrast of the extent and nature of the supporting database versus potentially inconsistent or missing information. The comparison was based on evolved Bradford Hill considerations rank ordered to reflect their relative contribution to WOE determinations of MOA taking into account increasing experience in their application internationally. This clarification of considerations for WOE determinations as a basis for comparative analysis is anticipated to contribute to increasing consistency in the application of MOA/HR analysis and potentially, transparency in separating science judgment from public policy considerations in regulatory risk assessment.

Epilepsy is a common neurologic disorder, affecting approximately 50 million people worldwide; nearly a third of these people have epilepsy that is not well controlled by a single antiepileptic drug (AED) and they usually require treatment with a combination of two or more AEDs. In recent years, many newer AEDs have been investigated as add-on therapy for focal epilepsy; losigamone is one of these drugs and is the focus of this systematic review. This is an update of a Cochrane review first published in 2012 (Cochrane Database of Systematic Reviews 2012, Issue 6) and updated in 2015. To investigate the efficacy and safety of losigamone when used as an add-on therapy for focal epilepsy. For the latest update on 9 February 2017, we searched the Cochrane Epilepsy Specialized Register, CENTRAL and MEDLINE . We searched trials registers and contacted the manufacturer of losigamone and authors of included studies for additional information. We did not impose any language restrictions. Randomized controlled, add-on trials comparing losigamone with placebo for focal epilepsy. Two review authors independently assessed trial quality and extracted data. The primary outcomes were 50% or greater reduction in seizure frequency and seizure freedom; the secondary outcomes were treatment withdrawal and adverse events. Results are presented as risk ratios (RRs) with 95% confidence intervals (CIs) or 99% CIs (for the individual listed adverse events to make an allowance for multiple testing). Two trials involving a total of 467 participants, aged over 18 years, were eligible for inclusion. Both trials assessed losigamone 1200 mg/day or 1500 mg/day as an add-on therapy for focal epilepsy. We assessed one trial as being of good methodological quality while the other was of uncertain quality. For the efficacy outcomes, results did show that participants taking losigamone were significantly more likely to achieve a 50% or greater reduction in seizure frequency (RR 1.76, 95% CI 1.14 to 2

Around half of people with epilepsy will not achieve seizure freedom on their first antiepileptic drug; many will require add-on treatment with another drug. Sometimes multiple treatment combinations are tried to achieve maximum seizure control, although around a third of people do not achieve complete seizure control. Lacosamide is an antiepileptic drug that has been licensed as an add-on treatment for partial epilepsy. To evaluate the efficacy and tolerability of lacosamide when used as an add-on treatment for patients with drug-resistant partial epilepsy. We searched the Cochrane Epilepsy Group's Specialized Register (21 May 2015), the Cochrane Central Register of Controlled Trials (CENTRAL , The Cochrane Library Issue 4, April 2015), MEDLINE (Ovid, 1946 to 21 May 2015), Scopus (1823 to 13 November 2014), ClinicalTrials.gov (21 May 2015) and the WHO International Clinical Trials Registry Platform (ICTRP, 21 May 2015). We imposed no language restrictions. We contacted UCB (sponsors of lacosamide) and experts in the field. Randomised controlled trials of add-on lacosamide in people with drug-resistant partial epilepsy. Two review authors independently assessed trials for inclusion and extracted the relevant data. We assessed the following outcomes: (1) 50% or greater reduction in seizure frequency; (2) seizure freedom; (3) treatment withdrawal for any reason; and (4) adverse events. Primary analyses were intention-to-treat. Summary risk ratios were estimated for each outcome. We included three trials in our review (1311 participants), which were classified as having low risk of bias. All trials were placebo-controlled and assessed doses ranging from 200 mg to 600 mg per day. Trial duration ranged from 24 to 26 weeks. All trials used adequate methods of randomisation and were double-blind. Overall the quality of the evidence was rated as moderate to high. The overall risk ratio for a 50% or greater reduction in seizure frequency for all doses of lacosamide compared

Although antidepressant medications are effective, they have a delayed onset of effect. Mirtazapine, an atypical antidepressant is an important option for add-on therapy in major depression. There is insufficient data on mirtazapine in Indian population; hence this study was designed to study the add-on effect of low-dose mirtazapine with selective serotonin reuptake inhibitors (SSRIs) in major depressive disorder (MDD) in Indian population. In an open, randomized study, 60 patients were divided into two groups. In Group A (n=30) patients received conventional SSRIs for 6 weeks. In Group B (n=30) patients received conventional SSRIs with low-dose mirtazapine for 6 weeks. Patients were evaluated at baseline and then at 1, 2, 3, 4, 5, and 6 weeks. There was significant improvement in Hamilton Depression Rating Scale (HDRS), Montgomery and Asberg depression rating scale (MADRS) scores (P<0.05) in both groups. Mirtazapine in low dose as add on therapy showed improvement in scores, had earlier onset of action, and more number of responders and remitters as compared to conventional treatment (P<0.05). No serious adverse event was reported in either of the groups. Low-dose mirtazapine as add-on therapy has shown better efficacy, earlier onset of action and more number of responders and remitters as compared to conventional treatment in MDD in Indian patients.

Dairy products have previously been reported to be associated with beneficial effects on body weight and metabolic risk markers. Moreover, primary data from the Diet, Obesity and Genes (DiOGenes) study indicate a weight-maintaining effect of a high-protein-low-glycaemic index diet. The objective of the present study was to examine putative associations between consumption of dairy proteins and changes in body weight and metabolic risk markers after weight loss in obese and overweight adults. Results were based on secondary analyses of data obtained from overweight and obese adults who completed the DiOGenes study. The study consisted of an 8-week weight-loss phase and a 6-month weight-maintenance (WM) phase, where the subjects were given five different diets varying in protein content and glycaemic index. In the present study, data obtained from all the subjects were pooled. Dairy protein intake was estimated from 3 d dietary records at two time points (week 4 and week 26) during the WM phase. Body weight and metabolic risk markers were determined at baseline (week -9 to -11) and before and at the end of the WM phase (week 0 and week 26). Overall, no significant associations were found between consumption of dairy proteins and changes in body weight and metabolic risk markers. However, dairy protein intake tended to be negatively associated with body weight gain (P=0·08; β=-0·17), but this was not persistent when controlled for total protein intake, which indicates that dairy protein adds no additional effect to the effect of total protein. Therefore, the present study does not report that dairy proteins are more favourable than other proteins for body weight regulation.

Weight gain and associated medical morbidity offset the reduction of extrapyramidal side effects associated with atypical antipsychotics. Efforts to control weight in antipsychotic-treated patients have yielded limited success. We studied the impact of an intensive 24-week program of diet, exercise, and counseling in 17 chronically psychotic patients (10 women, seven men) who entered at high average body weight (105.0+/-18.4 kg) and body mass index (BMI) (36.6+/-4.6 kg/m(2)). A total of 12 subjects who completed the initial 24 weeks elected to participate in an additional 24-week, less intensive extension phase. By 24 weeks, weight-loss/patient averaged 6.0 kg (5.7%) and BMI decreased to 34.5 (by 5.7%). Blood pressure decreased from 130/83 to 116/74 (11% improvement), pulse fell slightly, and serum cholesterol and triglyceride concentrations changed nonsignificantly. With less intensive management for another 24 weeks, subjects regained minimal weight (0.43 kg). These findings add to the emerging view that weight gain is a major health problem associated with modern antipsychotic drugs and that labor-intensive weight-control efforts in patients requiring antipsychotic treatment yield clinically promising benefits. Improved treatments without weight-gain risk are needed.

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

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.

Nintedanib and pirfenidone slow the progression of idiopathic pulmonary fibrosis (IPF), but the disease continues to progress. More data are needed on the safety and efficacy of combination therapy with nintedanib and add-on pirfenidone. To investigate safety, tolerability, and pharmacokinetic and exploratory efficacy endpoints in patients treated with nintedanib and add-on pirfenidone versus nintedanib alone. Patients with IPF and FVC greater than or equal to 50% predicted at screening who completed a 4- to 5-week run-in with nintedanib 150 mg twice daily without dose reduction or treatment interruption were randomized to receive nintedanib 150 mg twice daily with add-on pirfenidone (titrated to 801 mg three times daily) or nintedanib 150 mg twice daily alone in an open-label manner for 12 weeks. The primary endpoint was the percentage of patients with on-treatment gastrointestinal adverse events from baseline to Week 12. Analyses were descriptive and exploratory. On-treatment gastrointestinal adverse events were reported in 37 of 53 patients (69.8%) treated with nintedanib with add-on pirfenidone and 27 of 51 patients (52.9%) treated with nintedanib alone. Predose plasma trough concentrations of nintedanib were similar when it was administered alone or with add-on pirfenidone. Mean (SE) changes from baseline in FVC at Week 12 were -13.3 (17.4) ml and -40.9 (31.4) ml in patients treated with nintedanib with add-on pirfenidone (n = 48) and nintedanib alone (n = 44), respectively. Nintedanib with add-on pirfenidone had a manageable safety and tolerability profile in patients with IPF, in line with the adverse event profiles of each drug. These data support further research into combination regimens in the treatment of IPF. Clinical trial registered with www.clinicaltrials.gov (NCT02579603).

Interference Canceller Based on Cycle-and-Add Property for Single User Detection in DS-CDMA

NASA Astrophysics Data System (ADS)

Hettiarachchi, Ranga; Yokoyama, Mitsuo; Uehara, Hideyuki; Ohira, Takashi

In this paper, performance of a novel interference cancellation technique for the single user detection in a direct-sequence code-division multiple access (DS-CDMA) system has been investigated. This new algorithm is based on the Cycle-and-Add property of PN (Pseudorandom Noise) sequences and can be applied for both synchronous and asynchronous systems. The proposed strategy provides a simple method that can delete interference signals one by one in spite of the power levels of interferences. Therefore, it is possible to overcome the near-far problem (NFP) in a successive manner without using transmit power control (TPC) techniques. The validity of the proposed procedure is corroborated by computer simulations in additive white Gaussian noise (AWGN) and frequency-nonselective fading channels. Performance results indicate that the proposed receiver outperforms the conventional receiver and, in many cases, it does so with a considerable gain.

The interplay between gender, race and weight status: self perceptions and social consequences.

PubMed

Fletcher, Jason M

2014-07-01

This paper uses data from nearly 15,000 young adult respondents to the Add Health survey to examine racial and gender differences in the perceptions and social rewards to weight. The data include information on several typically unmeasured domains: self-perceptions of ideal weight, attractiveness ratings, and measured weight information, along with ties to a series of adult outcomes. Results show important gender and racial differences in ideal weight as well as differences for both self-perceived attractiveness and interviewer rated attractiveness. Findings also suggest the existence of large differences in socio-cultural rewards and sanctions for weight status. Black respondents, particularly women, appear to receive lower "obesity penalties" in both their self-perceived and interviewer accessed attractiveness ratings than other groups. These findings suggest the need to consider new classes of policies directed at shifting relative social benefits and consequences to weight status. Copyright © 2012 Elsevier B.V.

To compare the efficacy and safety of treatment with dapagliflozin versus that with placebo add-on to saxagliptin plus metformin in patients whose type 2 diabetes is inadequately controlled with saxagliptin plus metformin treatment. Patients receiving treatment with stable metformin (stratum A) (screening HbA1c level 8.0-11.5% [64-102 mmol/mol]) or stable metformin and a dipeptidyl peptidase-4 (DPP-4) inhibitor (stratum B) (HbA1c 7.5-10.5% [58-91 mmol/mol]) for ≥8 weeks received open-label saxagliptin 5 mg/day and metformin for 16 weeks (stratum A) or 8 weeks (stratum B) (saxagliptin replaced any DPP-4 inhibitor). Patients with inadequate glycemic control (HbA1c 7-10.5% [53-91 mmol/mol]) were randomized to receive placebo or dapagliflozin 10 mg/day plus saxagliptin and metformin. The primary end point was the change in HbA1c from baseline to week 24. Secondary end points included fasting plasma glucose (FPG) level, 2-h postprandial glucose (PPG) level, body weight, and proportion of patients achieving an HbA1c level of <7% (53 mmol/mol). Treatment with dapagliflozin add-on to saxagliptin plus metformin resulted in a greater mean HbA1c reduction than placebo (-0.82 vs. -0.10% [-9 vs. -1.1 mmol/mol], P < 0.0001). Significantly greater reductions in FPG level, 2-h PPG level, and body weight were observed, and more patients achieved an HbA1c level of <7% (53 mmol/mol) with treatment with dapagliflozin versus placebo. Adverse events were similar across treatment groups, with a low overall risk of hypoglycemia (∼1%). Genital infections developed in more patients with dapagliflozin treatment (5%) than with placebo (0.6%). Triple therapy with dapagliflozin add-on to saxagliptin plus metformin improves glycemic control and is well tolerated in patients whose type 2 diabetes is inadequately controlled with saxagliptin plus metformin therapy. © 2015 by the American Diabetes Association.

2017-06-01

Sensory feedback systems have been of great interest in upper-limb prosthetics. Despite tremendous research, there are no commercial modality-matched feedback systems. This article aims to introduce the first detachable and feedback add-on option that can be attached to in-use prostheses. A sensory feedback system was tested on a below-elbow myoelectric prosthesis. The aim was to have the amputee grasp fragile objects without crushing while other accidental feedback sources were blocked. A total of 8 successful trials (out of 10) showed that sensory feedback system decreased the amputee's visual dependency by improving awareness of his prosthesis. Sensory feedback system can be used either as post-fabrication (prosthetic add-on option) or para-fabrication (incorporated into prosthetic design). The use of these direct feedback systems can be explored with a current prosthesis before ordering new high-tech prosthesis. Clinical relevance This technical note introduces the first attach/detach-able sensory feedback system that can simply be added to in-use (myo)electric prosthesis, with no obligation to change prosthesis design or components.

2014-12-01

Our study aims to provide an in-depth analysis of behavioral strategies, psychological factors, and social contributors to adolescent weight loss and weight loss maintenance among participants in the Adolescent Weight Control Registry (AWCR). Qualitative analyses were conducted using semi-structured interview data from 40 participants from the AWCR who successfully lost ≥10 lbs and maintained their weight loss for at least one year. In contrast to existing literature, our findings suggest that primary motivating factors for adolescent weight loss may be intrinsic (e.g., desire for better health, desire to improve self-worth) rather than extrinsic. In addition, life transitions (e.g., transition to high school) were identified as substantial motivators for weight-related behavior change. Peer and parental encouragement and instrumental support were widely endorsed as central to success. The most commonly endorsed weight loss maintenance strategies included attending to dietary intake and physical activity levels, and making self-corrections when necessary. Results from this study highlight considerations for future adolescent weight control treatment development.

Most people with epilepsy have a good prognosis and their seizures can be well controlled with the use of a single antiepileptic drug, but up to 30% develop refractory epilepsy, especially those with partial seizures. In this review we summarize the current evidence regarding oxcarbazepine when used as an add-on treatment for drug-resistant partial epilepsy. To evaluate the effects of oxcarbazepine when used as an add-on treatment for drug-resistant partial epilepsy. We searched the Cochrane Epilepsy Group's Specialized Register (28 March 2006), the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library Issue 1, 2006), MEDLINE (1966 to March 2006). No language restrictions were imposed. We checked the reference lists of retrieved studies for additional reports of relevant studies. We also contacted Novartis (manufacturers of oxcarbazepine) and experts in the field. Randomized, placebo-controlled, double-blinded, add-on trials of oxcarbazepine in patients with drug-resistant partial epilepsy. Two review authors independently assessed trials for inclusion and extracted the relevant data. The following outcomes were assessed : (a) 50% or greater reduction in seizure frequency; (b) treatment withdrawal (any reason); (c) side effects. Primary analyses were intention-to-treat. Summary odds ratios were estimated for each outcome. Two trials were included representing 961 randomized patients.Overall Odds Ratio (OR) (95% Confidence Interval (CIs)) for 50% or greater reduction in seizure frequency compared to placebo 2.96 (2.20, 4.00).Treatment withdrawal OR (95% CIs) compared to placebo 2.17 (1.59, 2.97).Side effects: OR (99% CIs) compared to placebo, ataxia 2.93 (1.72, 4.99); dizziness 3.05 (1.99, 4.67); fatigue 1.80 (1.02, 3.19); nausea 2.88 (1.77, 4.69); somnolence 2.55 (1.84, 3.55); diplopia 4.32 (2.65, 7.04), were significantly associated with oxcarbazepine.

Deri, Robert J.; Strand, Oliver T.; Garrett, Henry E.

2002-01-01

An optical add/drop filter for wavelength division multiplexed systems and construction methods are disclosed. The add/drop filter includes a first ferrule having a first pre-formed opening for receiving a first optical fiber; an interference filter oriented to pass a first set of wavelengths along the first optical fiber and reflect a second set of wavelengths; and, a second ferrule having a second pre-formed opening for receiving the second optical fiber, and the reflected second set of wavelengths. A method for constructing the optical add/drop filter consists of the steps of forming a first set of openings in a first ferrule; inserting a first set of optical fibers into the first set of openings; forming a first set of guide pin openings in the first ferrule; dividing the first ferrule into a first ferrule portion and a second ferrule portion; forming an interference filter on the first ferrule portion; inserting guide pins through the first set of guide pin openings in the first ferrule portion and second ferrule portion to passively align the first set of optical fibers; removing material such that light reflected from the interference filter from the first set of optical fibers is accessible; forming a second set of openings in a second ferrule; inserting a second set of optical fibers into the second set of openings; and positioning the second ferrule with respect to the first ferrule such that the second set of optical fibers receive the light reflected from the interference filter.

An optically pumped thermo-optic (TO) silicon ring add-drop filter with fast thermal response is experimentally demonstrated. We propose that metal-insulator-metal (MIM) light absorber can be integrated into silicon TO devices, acting as a localized heat source which can be activated remotely by a pump beam. The MIM absorber design introduces less thermal capacity to the device, compared to conventional electrically-driven approaches. Experimentally, the absorber-integrated add-drop filter shows an optical response time of 13.7 μs following the 10%-90% rule (equivalent to a exponential time constant of 5 μs) and a wavelength shift over pump power of 60 pm/mW. The photothermally tunable add-drop filter may provide new perspectives for all-optical routing and switching in integrated Si photonic circuits.

Equilibrium expert: an add-in to Microsoft Excel for multiple binding equilibrium simulations and parameter estimations.

PubMed

Raguin, Olivier; Gruaz-Guyon, Anne; Barbet, Jacques

2002-11-01

An add-in to Microsoft Excel was developed to simulate multiple binding equilibriums. A partition function, readily written even when the equilibrium is complex, describes the experimental system. It involves the concentrations of the different free molecular species and of the different complexes present in the experiment. As a result, the software is not restricted to a series of predefined experimental setups but can handle a large variety of problems involving up to nine independent molecular species. Binding parameters are estimated by nonlinear least-square fitting of experimental measurements as supplied by the user. The fitting process allows user-defined weighting of the experimental data. The flexibility of the software and the way it may be used to describe common experimental situations and to deal with usual problems such as tracer reactivity or nonspecific binding is demonstrated by a few examples. The software is available free of charge upon request.

Evolutionary Construction of Block-Based Neural Networks in Consideration of Failure

NASA Astrophysics Data System (ADS)

Takamori, Masahito; Koakutsu, Seiichi; Hamagami, Tomoki; Hirata, Hironori

In this paper we propose a modified gene coding and an evolutionary construction in consideration of failure in evolutionary construction of Block-Based Neural Networks. In the modified gene coding, we arrange the genes of weights on a chromosome in consideration of the position relation of the genes of weight and structure. By the modified gene coding, the efficiency of search by crossover is increased. Thereby, it is thought that improvement of the convergence rate of construction and shortening of construction time can be performed. In the evolutionary construction in consideration of failure, the structure which is adapted for failure is built in the state where failure occured. Thereby, it is thought that BBNN can be reconstructed in a short time at the time of failure. To evaluate the proposed method, we apply it to pattern classification and autonomous mobile robot control problems. The computational experiments indicate that the proposed method can improve convergence rate of construction and shorten of construction and reconstruction time.

The long-term weight management of obesity remains a very difficult task, associated with a high risk of failure and weight regain. However, many people report that they have successfully managed weight loss maintenance in the long term. Several factors have been associated with better weight loss maintenance in long-term observational and randomized studies. A few pertain to the behavioral area (eg, high levels of physical activity, eating a low-calorie, low-fat diet; frequent self-monitoring of weight), a few to the cognitive component (eg, reduced disinhibition, satisfaction with results achieved, confidence in being able to lose weight without professional help), and a few to personality traits (eg, low novelty seeking) and patient–therapist interaction. Trials based on the most recent protocols of lifestyle modification, with a prolonged extended treatment after the weight loss phase, have also shown promising long-term weight loss results. These data should stimulate the adoption of a lifestyle modification-based approach for the management of obesity, featuring a nonphysician lifestyle counselor (also called “lifestyle trainer” or “healthy lifestyle practitioner”) as a pivotal component of the multidisciplinary team. The obesity physicians maintain a primary role in engaging patients, in team coordination and supervision, in managing the complications associated with obesity and, in selected cases, in the decision for drug treatment or bariatric surgery, as possible more intensive, add-on interventions to lifestyle treatment.

Lower cost alternatives are needed for the traditional in-person behavioral weight loss programs to overcome challenges of lowering the worldwide prevalence of overweight and obesity. Smartphones have become ubiquitous and provide a unique platform to aid in the delivery of a behavioral weight loss program. The technological capabilities of a smartphone may address certain limitations of a traditional weight loss program, while also reducing the cost and burden on participants, interventionists, and health care providers. Awareness of the advantages smartphones offer for weight loss has led to the rapid development and proliferation of weight loss applications (apps). The built-in features and the mechanisms by which they work vary across apps. Although there are an extraordinary number of a weight loss apps available, most lack the same magnitude of evidence-based behavior change strategies typically used in traditional programs. As features develop and new capabilities are identified, we propose a conceptual model as a framework to guide the inclusion of features that can facilitate behavior change and lead to reductions in weight. Whereas the conventional wisdom about behavior change asserts that more is better (with respect to the number of behavior change techniques involved), this model suggests that less may be more because extra techniques may add burden and adversely impact engagement. Current evidence is promising and continues to emerge on the potential of smartphone use within weight loss programs; yet research is unable to keep up with the rapidly improving smartphone technology. Future studies are needed to refine the conceptual model’s utility in the use of technology for weight loss, determine the effectiveness of intervention components utilizing smartphone technology, and identify novel and faster ways to evaluate the ever-changing technology.

Food shopping and weight concern. Balancing consumer and body normality.

PubMed

Nielsen, Annemette; Holm, Lotte

2014-11-01

The desire to achieve a normal, culturally acceptable body is often seen as the main driver of food-consumption practices adopted by individuals who are concerned about their body weight. In social research into weight management self-control is therefore often a central theme. Turning the focus towards practices and values related to food shopping, this study adds to our understanding of central features in perceptions of normality among people with weight concerns. In a qualitative study 25 people who participated in a dietary intervention trial in Denmark were interviewed and five people were observed. The study shows that the aim of achieving a normal body does not eclipse the importance of enacting values linked to ideas of the 'normal consumer'. Using empirical examples, the study illuminates how consumer freedom is attained in ways that are both complementary to, and in conflict with, practices and experiences of controlling food intake. The paper suggests that freedom and control are composite and complementary ideals of normality for people with weight concerns. On the basis of this insight, the authors discuss the contribution the paper makes to existing studies of weight management and food consumption. Copyright © 2014 Elsevier Ltd. All rights reserved.

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 primary objective was to evaluate the efficacy and safety of droxidopa as add-on therapy in improving stiffness, tremors and other motor functions and activities of daily living for moderate-to-severe Parkinson's disease (PD). PD patients, above Hoehn-Yahr III (including Hoehn-Yahr III), were randomly assigned to drug therapy (droxidopa 600 mg/day for 8 weeks) or placebo. Efficacy indicators were the Unified Parkinson's Disease Rating Scale (UPDRS) part I, II, III subscale, Clinical Global Impression (CGI) rating score, and individual symptom scores (e.g. stiffness, tremors), to evaluate motor function and activities of daily life. There are 109 patients in the droxidopa group, and 110 in the placebo group, at baseline, there were no differences between the two groups for age, body weight, disease severity and previous drugs therapy. At days 14 and 57 of droxidopa add on treatment, UPDRS-II scores reflecting activities of daily life and UPDRS-III scores reflecting motor functions were significantly different compared to the pre-treatment baseline scores (P < 0.01), UPDRS- II and UPDRS-III scores at day 14 and day 57 were also significantly different (P < 0.01) between the two groups. Individual motor symptoms such as stiffness, resting tremor, and alternate hand motion were also significantly improved with droxidopa on days 14 and 57 of treatment (P < 0.01 vs placebo), showing that droxidopa is effective in improving rigidity, tremor and alternate motion of hand. Droxidopa was effective as symptomatic adjunct therapy, improved significantly motor function and activities of daily living, benefited patients with signs of tremor and Stiffness.

[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.

We propose a novel system of the dynamic optical tweezers generated by a dark soliton in the fiber optic loop. A dark soliton known as an optical tweezer is amplified and tuned within the microring resonator system. The required tunable tweezers with different widths and powers can be controlled. The analysis of dark-bright soliton conversion using a dark soliton pulse propagating within a microring resonator system is analyzed. The dynamic behaviors of soliton conversion in add/drop filter is also analyzed. The control dark soliton is input into the system via the add port of the add/drop filter. The dynamic behavior of the dark-bright soliton conversion is observed. The required stable signal is obtained via a drop and throughput ports of the add/drop filter with some suitable parameters. In application, the trapped light/atom and transportation can be realized by using the proposed system.

2011-09-01

Despite the well-known recidivism of obesity, surprisingly little is known about the composition of body weight during weight regain. The objective of this study was to determine whether the composition of body weight regained after intentional weight loss is similar to the composition of body weight lost. The design was a follow-up to a randomized controlled trial of weight loss in which body composition was analyzed and compared in 78 postmenopausal women before the intervention, immediately after the intervention, and 6 and 12 mo after the intervention. All body mass and composition variables were lower immediately after weight loss than at baseline (all P < 0.05). More fat than lean mass was lost with weight loss, which resulted in body-composition changes favoring a lower percentage of body fat and a higher lean-to-fat mass ratio (P < 0.001). Considerable interindividual variability in weight regain was noted (CV = 1.07). In women who regained ≥2 kg body weight, a decreasing trend in the lean-to-fat mass ratio was observed, which indicated greater fat mass accretion than lean mass accretion (P < 0.001). Specifically, for every 1 kg fat lost during the weight-loss intervention, 0.26 kg lean tissue was lost; for every 1 kg fat regained over the following year, only 0.12 kg lean tissue was regained. Although not all postmenopausal women who intentionally lose weight will regain it within 1 y, the data suggest that fat mass is regained to a greater degree than is lean mass in those who do experience some weight regain. The health ramifications of our findings remain to be seen.

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.

Dyslexia, attention deficit hyperactivity disorder (ADHD), and attention deficit disorder (ADD) show distinct clinical profiles that may include auditory and language-related impairments. Currently, an objective brain-based diagnosis of these developmental disorders is still unavailable. We investigated the neuro-auditory systems of dyslexic, ADHD, ADD, and age-matched control children (N = 147) using neuroimaging, magnetencephalography and psychoacoustics. All disorder subgroups exhibited an oversized left planum temporale and an abnormal interhemispheric asynchrony (10-40 ms) of the primary auditory evoked P1-response. Considering right auditory cortex morphology, bilateral P1 source waveform shapes, and auditory performance, the three disorder subgroups could be reliably differentiated with outstanding accuracies of 89-98%. We therefore for the first time provide differential biomarkers for a brain-based diagnosis of dyslexia, ADHD, and ADD. The method allowed not only allowed for clear discrimination between two subtypes of attentional disorders (ADHD and ADD), a topic controversially discussed for decades in the scientific community, but also revealed the potential for objectively identifying comorbid cases. Noteworthy, in children playing a musical instrument, after three and a half years of training the observed interhemispheric asynchronies were reduced by about 2/3, thus suggesting a strong beneficial influence of music experience on brain development. These findings might have far-reaching implications for both research and practice and enable a profound understanding of the brain-related etiology, diagnosis, and musically based therapy of common auditory-related developmental disorders and learning disabilities.

Metformin is an established first-line treatment for type 2 diabetes mellitus (T2DM) patients, but intensification of oral anti-diabetes therapy is usually required over time. A large observational study of 45,868 T2DM patients in 27 countries (EDGE) was conducted to compare the effectiveness and safety of vildagliptin as add-on therapy to another oral anti-diabetes drug (OAD) vs other dual OAD combinations. This report presents results from a post-hoc analysis of patients in Germany who received vildagliptin or a sulfonylurea (SU) in combination with metformin. Patients inadequately controlled with monotherapy became eligible only after the add-on treatment was finalized. Patients included were assigned to receive either vildagliptin or another OAD (SUs, thiazolidinediones, glinides, α-glucosidase inhibitors, or metformin; DPP-4 inhibitors or glucagon-like peptide-1 [GLP-1] mimetics/analogs were excluded). The primary end-point was the proportion of patients achieving a reduction in HbA1c >0.3% without peripheral edema, hypoglycemia, discontinuation due to gastrointestinal event, or weight gain ≥5%. Of 8887 patients enrolled in Germany, 6439 received vildagliptin and 971 received SUs as add-on to metformin. The primary end-point was reached in 34.9% and 29.6% of patients in the vildagliptin and SU groups, respectively, with an unadjusted odds ratio of 1.27 (95% CI = 1.09, 1.47; p = 0.001). HbA1c decreased in both cohorts from baseline (-0.7% with vildagliptin vs -0.5% with SUs), with a mean between-group difference of -0.2% (95% CI = -0.22, -0.09). The number of hypoglycemic events was 4-fold higher in the SU group than in the vildagliptin group (vildagliptin = 0.11%; SU = 0.41%). In a real-life setting, vildagliptin was associated with a numerically greater reduction in HbA1c, less hypoglycemia, and more patients reaching target HbA1c without hypoglycemia or weight gain compared with SUs.

To evaluate the proportion of patients with type 2 diabetes mellitus (T2DM) achieving reductions in both glycated hemoglobin (HbA1c) and body weight with canagliflozin, a sodium glucose co-transporter 2 inhibitor, versus sitagliptin over 52 weeks. Data were pooled from two, randomized, Phase 3 studies of canagliflozin 100 and 300 mg versus sitagliptin 100 mg as add-on to metformin, and canagliflozin 300 mg versus sitagliptin 100 mg as add-on to metformin plus sulfonylurea (N = 1856). The composite end points of change from baseline in both HbA1c <0% and body weight <0 kg, and attainment of HbA1c <7.0% and body weight reduction ≥5% at Week 52 were evaluated. Safety was assessed based on adverse event reports. Canagliflozin provided reductions in HbA1c and body weight over 52 weeks versus sitagliptin. A greater proportion of patients had both HbA1c and body weight reductions with canagliflozin 100 and 300 mg versus sitagliptin 100 mg (67.7%, 72.6%, and 44.1%, respectively). Among patients with HbA1c and body weight reductions, more patients achieved the composite end point of HbA1c <7.0% and body weight reduction ≥5% with canagliflozin 100 and 300 mg versus sitagliptin 100 mg (18.9%, 18.3%, and 5.7%, respectively). Canagliflozin was generally well tolerated. A greater proportion of patients with T2DM achieved reductions in both HbA1c and body weight, and more patients with HbA1c and body weight reductions achieved HbA1c <7.0% and body weight reduction ≥5% with canagliflozin versus sitagliptin over 52 weeks. www.ClinicalTrials.gov identifiers are NCT01106677; NCT01137812.

Regulating the energy density of food could be used as a novel approach for successful body weight reduction in clinical practice. The aim of this study was to conduct a systemic review of the literature on the relationship between food energy density and body weight changes in obese adults to obtain solid evidence supporting this approach. The search process was based on the selection of publications in the English language listed in public databases. A meta-analysis was performed to combine individual study results. Thirteen experimental and observational studies were identified and included in the final analysis. The analyzed populations consist of 3628 individuals aged 18 to 66 years. The studies varied greatly in terms of study populations, study design and applied dietary approaches. The meta-analysis revealed a significant association between low energy density foods and body weight reduction, i.e., −0.53 kg when low energy density foods were eaten (95% CI: −0.88, −0.19). In conclusions, this study adds evidence which supports the energy density of food as a simple but effective measure to manage weight in the obese with the aim of weight reduction. PMID:27104562

Physically Active Rats Lose More Weight during Calorie Restriction

Daily physical activity shows substantial inter-individual variation, and low physical activity is associated with obesity and weight gain. Elevated physical activity is also associated with high intrinsic aerobic capacity, which confers considerable metabolic health benefits. Rats artificially selected for high intrinsic aerobic capacity (high-capacity runners, HCR) are more physically active than their low-capacity counterparts (low-capacity runners, LCR). To test the hypothesis that physical activity counters metabolic thriftiness, we measured physical activity and weight loss during three weeks of 50% calorie restriction (CR) in the HCR and LCR rat lines. At baseline, HCR ate more and were more active than LCR; this was seen in male rats, where LCR are considerably heavier than HCR, as well as in a set of female rats where body weight did not differ between the lines, demonstrating that this effect is consistent across sex and not secondary to body weight. We show for the first time that HCR lose more weight than LCR relative to baseline. Physical activity levels declined throughout CR, and this was more pronounced in HCR than in LCR, yet some aspects of activity remained elevated in HCR relative to LCR even during CR. This is consistent with the idea that low physical activity contributes to metabolic thriftiness during food restriction, allowing LCR to defend body mass, particularly lean mass. This has implications for physical activity during diet-induced weight loss, the genetic underpinnings of individual differences in weight loss during a diet, and the potential evolutionary opposition between metabolic thriftiness and aerobic capacity.

Obstructive sleep apnea (OSA) together with metabolic disorders is common in severely obese patients. Weight reduction is considered as a treatment modality in these cases while few of them can succeed in considerable weight loss. Here, we present a severely obese man with body mass index of 54 suffered from OSA, type 2 diabetes, hypothyroidism, and hypertension. He intentionally lost 80 kilograms weight during the 2-year follow-up. Diabetes and hypertension completely resolved with considerable improvement in OSA syndrome after this huge weight reduction.

Drinking 500 mL of water 30 minutes before each meal can be used in conjunction with a hypocaloric diet to lead to greater weight loss in overweight or obese middle-aged and older adults. Pre-meal water consumption for weight loss is an easy to implement intervention. It has NHMRC Level 2 evidence of efficacy and adverse effects are unlikely. There are some considerations, and the intervention would be contraindicated in patients with congestive cardiac failure, and in those with severe renal impairment.

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.

Attitude of weight during 12. up to the 42. week of pregnancy was observed with 946 pregnant women which had an regular course of pregnancy. The normal range of the weekly grow of weight was given in an average for this period, and dissemination was found out. By this, compared with all the pregnants, a separation was made when representing women who brought forth compared with all the pregnants, a separation was made when representing women who bought forth the first time and such who had given birth to more children. Further on, the variety of weight attitude depending from parity, distribution of the age, and body tallness was taken into consideration. This substantially showed independence of the masium grow of weight from parity, age, and tallness of the pregnants between the 21. and 25. week of pregnancy. Altogether, those who give their first birth as well as younger and taller women show a stronger grow of weight during pregnancy than those who have already born more children, or older and smaller women.

Anthropometric, lifestyle and psychosocial factors were measured at baseline and then quarterly for 1 year in 572 healthy adult volunteers from Central Massachusetts who were recruited between 1994 and 1998. Linear mixed models were used to analyze the relationship between body weight and potential predictors, including demographic (e.g., age, educational level), lifestyle (e.g., diet, physical activity, smoking), and psychosocial (e.g., anxiety, depression) factors. Over the 1-year study period, on average, men gained 0.3 kg and women lost 0.2 kg. Predictors of lower body weight at baseline in both men and women included current cigarette smoking, greater leisure-time physical activity, and lower depression and anxiety scores. Lower body weights were associated with a lower percentage of caloric intake from protein and greater occupational physical activity levels only among men; and with higher education level only among women. Longitudinal predictors of 1-year weight gain among women included increased total caloric intake and decreased leisure-time physical activity, and among men, greater anxiety scores. Demographic, lifestyle and psychosocial factors are independently related to naturally occurring changes in body weight and have marked differential gender effects. These effects should be taken into consideration when designing interventions for weight-loss and maintenance at the individual and population levels.

To compare the long-term safety, tolerability and efficacy of saxagliptin vs. glipizide as add-on therapy to metformin. Adults with glycated haemoglobin (HbA1c) > 6.5-10% (on stable metformin ≥ 1500 mg/day) were randomised to saxagliptin 5 mg/day (n = 428) or glipizide titrated from 5 to 20 mg/day (mean dose 15 mg/day; n = 430) for 52 weeks with a 52-week extension (NCT00575588). Assessment of the long-term safety, tolerability and efficacy of add-on saxagliptin vs. glipizide after 104 weeks was a tertiary objective of the initial 52-week study. Saxagliptin was well tolerated during the 104-week period; 67.1% of patients receiving saxagliptin vs. 72.6% receiving glipizide had ≥ 1 adverse event (AE), and few patients (4.9% vs. 5.6%) discontinued owing to AEs. Fewer patients treated with saxagliptin experienced hypoglycaemia (3.5% vs. 38.4% with glipizide; difference, -34.9%, 95% CI, -39.8 to -30.0) or confirmed hypoglycaemia (0 vs. 9.1% with glipizide). Weight loss was observed with saxagliptin (-1.5 kg) vs. weight gain with glipizide (+1.3 kg; between-group difference, -2.8 kg, 95% CI, -3.32 kg to -2.20 kg). Change from baseline in HbA1c was -0.41 ± 0.04% with saxagliptin and -0.35 ± 0.04% with glipizide (between-group difference, -0.05%, 95% CI, -0.17 to 0.06%). A post hoc analysis showed that the proportion of patients with baseline HbA1c ≥ 7% who achieved HbA1c < 7% (observed data) at week 104 was 23.1% for saxagliptin + metformin and 22.7% for glipizide + metformin. A lower risk of hypoglycaemia and reduced body weight were observed with saxagliptin vs. glipizide. No other clinically significant differences were observed between groups in safety profile. No significant between-group differences were observed for reductions in glycaemic parameters. After week 24, a smaller weekly rise in HbA1c was observed with saxagliptin vs. glipizide as add-on therapy to metformin.

The weighted ranking as used in this report is an attempt to combine total air release with recognized exposure limit for each toxic chemical to arrive at a single ranking factor called Release Exposure Index (REI) which takes both release amount and degree of hazard into consideration. The REIs can then be used in decision making to prioritize how these chemicals are addressed. 2 tabs.

Age-related factors in the relationship between foot measurements and living stature and body weight.

PubMed

Atamturk, Derya; Duyar, Izzet

2008-11-01

The measurements of feet and footprints are especially important in forensic identification, as they have been used to predict the body height and weight of victims or suspects. It can be observed that the subjects of forensic-oriented studies are generally young adults. That is to say, researchers rarely take into consideration the body's proportional changes with age. Hence, the aim of this study is to generate equations which take age and sex into consideration, when stature and body weight are estimated from foot and footprints dimensions. With this aim in mind, we measured the stature, body weight, foot length and breadth, heel breadth, footprint length and breadth, and footprint heel breadth of 516 volunteers (253 males and 263 females) aged between 17.6 and 82.9 years using standard measurement techniques. The sample population was divided randomly into two groups. Group 1, the study group, consisted of 80% of the sample (n = 406); the remaining 20% were assigned to the cross-validation group or Group 2 (n = 110). In the first stage of the study, we produced equations for estimating stature and weight using a stepwise regression technique. Then, their reliability was tested on Group 2 members. Statistical analyses showed that the ratios of foot dimensions to stature and body weight change considerably with age and sex. Consequently, the regression equations which include these variables yielded more reliable results. Our results indicated that age and sex should be taken into consideration when predicting human body height and weight for forensic purposes.

Postpartum weight self-management: a concept analysis.

PubMed

Ohlendorf, Jennifer M

2013-01-01

The aim of this concept analysis is to create a clear definition and framework to guide weight self-management research and promotion of healthy weight self-management during the postpartum period. A woman's ability to manage her weight through the postpartum transition has lifelong implications for her weight status. This concept analysis was guided by Walker and Avant (2005). A broad search of sources was performed, yielding 56 articles in which postpartum weight self-management was the main focus. From consideration of the attributes of postpartum weight self-management, a descriptive, situation-specific theory emerged: Postpartum weight self-management is a process by which the transition to motherhood is viewed by the woman as an opportunity to intentionally engage in healthy weight self-management behaviors by minimizing the salient inhibitors and maximizing the salient facilitators to action. This analysis provides a clarification of the process concept of postpartum weight self-management and its consequences, giving direction for measurement, clinical application, and further research. Future nursing interventions and research should be aimed at helping women to view the postpartum period as a normative transition in which they have the opportunity to take charge of their own health and the health of their family.

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 determine the effect of a bifocal add and manifest correction on accommodative lag in myopic children with high accommodative lag, who have been reported to have the greatest reduction in myopia progression with progressive addition lenses (PALs). Monocular accommodative lag to a 4-D Badal stimulus was measured on two occasions 6 months apart in 83 children (mean ± SD age, 9.9 ± 1.3 years) with high lag randomized to wearing single-vision lenses (SVLs) or PALs. Accommodative lag was measured with the following corrections: habitual, manifest, manifest with +2.00-D add, and habitual with +2.00-D add (6-month visit only). At baseline, accommodative lag was higher (1.72 ± 0.37 D; mean ± SD) when measured with manifest correction than with habitual correction (1.51 ± 0.50; P < 0.05). This higher lag with manifest correction correlated with a larger amount of habitual undercorrection at baseline (r = -0.29, P = 0.009). A +2.00-D add over the manifest correction reduced lag by 0.45 ± 0.34 D at baseline and 0.33 ± 0.38 D at the 6-month visit. Lag results at 6 months were not different between PAL and SVL wearers (P = 0.92). A +2.00-D bifocal add did not eliminate accommodative lag and reduced lag by less than 25% of the bifocal power, indicating that children mainly responded to a bifocal by decreasing accommodation. If myopic progression is substantial, measuring lag with full correction can overestimate the hyperopic retinal blur that a child most recently experienced. (ClinicalTrials.gov number, NCT00335049.).

ATRX ADD domain links an atypical histone methylation recognition mechanism to human mental-retardation syndrome

DOE Office of Scientific and Technical Information (OSTI.GOV)

Iwase, Shigeki; Xiang, Bin; Ghosh, Sharmistha

ATR-X (alpha-thalassemia/mental retardation, X-linked) syndrome is a human congenital disorder that causes severe intellectual disabilities. Mutations in the ATRX gene, which encodes an ATP-dependent chromatin-remodeler, are responsible for the syndrome. Approximately 50% of the missense mutations in affected persons are clustered in a cysteine-rich domain termed ADD (ATRX-DNMT3-DNMT3L, ADD{sub ATRX}), whose function has remained elusive. Here we identify ADD{sub ATRX} as a previously unknown histone H3-binding module, whose binding is promoted by lysine 9 trimethylation (H3K9me3) but inhibited by lysine 4 trimethylation (H3K4me3). The cocrystal structure of ADD{sub ATRX} bound to H3{sub 1-15}K9me3 peptide reveals an atypical composite H3K9me3-binding pocket,more » which is distinct from the conventional trimethyllysine-binding aromatic cage. Notably, H3K9me3-pocket mutants and ATR-X syndrome mutants are defective in both H3K9me3 binding and localization at pericentromeric heterochromatin; thus, we have discovered a unique histone-recognition mechanism underlying the ATR-X etiology.« less

Physically active rats lose more weight during calorie restriction.

2015-02-01

Daily physical activity shows substantial inter-individual variation, and low physical activity is associated with obesity and weight gain. Elevated physical activity is also associated with high intrinsic aerobic capacity, which confers considerable metabolic health benefits. Rats artificially selected for high intrinsic aerobic capacity (high-capacity runners, HCR) are more physically active than their low-capacity counterparts (low-capacity runners, LCR). To test the hypothesis that physical activity counters metabolic thriftiness, we measured physical activity and weight loss during three weeks of 50% calorie restriction (CR) in the HCR and LCR rat lines. At baseline, HCR ate more and were more active than LCR; this was seen in male rats, where LCR are considerably heavier than HCR, as well as in a set of female rats where body weight did not differ between the lines, demonstrating that this effect is consistent across sex and not secondary to body weight. We show for the first time that HCR lose more weight than LCR relative to baseline. Physical activity levels declined throughout CR, and this was more pronounced in HCR than in LCR, yet some aspects of activity remained elevated in HCR relative to LCR even during CR. This is consistent with the idea that low physical activity contributes to metabolic thriftiness during food restriction, allowing LCR to defend body mass, particularly lean mass. This has implications for physical activity during diet-induced weight loss, the genetic underpinnings of individual differences in weight loss during a diet, and the potential evolutionary opposition between metabolic thriftiness and aerobic capacity.

Bourke, Julius H.; Wall, Matthew B.

2015-01-01

Pharmacological Magnetic Resonance Imaging (phMRI) is a variant of conventional MRI that adds pharmacological manipulations in order to study the effects of drugs, or uses pharmacological probes to investigate basic or applied (e.g., clinical) neuroscience questions. Issues that may confound the interpretation of results from various types of phMRI studies are briefly discussed, and a set of methodological strategies that can mitigate these problems are described. These include strategies that can be employed at every stage of investigation, from study design to interpretation of resulting data, and additional techniques suited for use with clinical populations are also featured. Pharmacological MRI is a challenging area of research that has both significant advantages and formidable difficulties, however with due consideration and use of these strategies many of the key obstacles can be overcome.

Discovering disease-associated genes in weighted protein-protein interaction networks

NASA Astrophysics Data System (ADS)

Cui, Ying; Cai, Meng; Stanley, H. Eugene

2018-04-01

Although there have been many network-based attempts to discover disease-associated genes, most of them have not taken edge weight - which quantifies their relative strength - into consideration. We use connection weights in a protein-protein interaction (PPI) network to locate disease-related genes. We analyze the topological properties of both weighted and unweighted PPI networks and design an improved random forest classifier to distinguish disease genes from non-disease genes. We use a cross-validation test to confirm that weighted networks are better able to discover disease-associated genes than unweighted networks, which indicates that including link weight in the analysis of network properties provides a better model of complex genotype-phenotype associations.

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.

Spectral data compression using weighted principal component analysis with consideration of human visual system and light sources

NASA Astrophysics Data System (ADS)

Cao, Qian; Wan, Xiaoxia; Li, Junfeng; Liu, Qiang; Liang, Jingxing; Li, Chan

2016-10-01

This paper proposed two weight functions based on principal component analysis (PCA) to reserve more colorimetric information in spectral data compression process. One weight function consisted of the CIE XYZ color-matching functions representing the characteristic of the human visual system, while another was made up of the CIE XYZ color-matching functions of human visual system and relative spectral power distribution of the CIE standard illuminant D65. The improvement obtained from the proposed two methods were tested to compress and reconstruct the reflectance spectra of 1600 glossy Munsell color chips and 1950 Natural Color System color chips as well as six multispectral images. The performance was evaluated by the mean values of color difference under the CIE 1931 standard colorimetric observer and the CIE standard illuminant D65 and A. The mean values of root mean square errors between the original and reconstructed spectra were also calculated. The experimental results show that the proposed two methods significantly outperform the standard PCA and another two weighted PCA in the aspects of colorimetric reconstruction accuracy with very slight degradation in spectral reconstruction accuracy. In addition, weight functions with the CIE standard illuminant D65 can improve the colorimetric reconstruction accuracy compared to weight functions without the CIE standard illuminant D65.

Telomeres are important contributors to genome stability, as they prevent linear chromosome end degradation and contribute to the avoidance of telomeric fusions. An important component of the telomeres is the heterochromatin protein 1a (HP1a). Mutations in Su(var)205, the gene encoding HP1a in Drosophila, result in telomeric fusions, retrotransposon regulation loss and larger telomeres, leading to chromosome instability. Previously, it was found that several proteins physically interact with HP1a, including dXNP and dAdd1 (orthologues to the mammalian ATRX gene). In this study, we found that mutations in the genes encoding the dXNP and dAdd1 proteins affect chromosome stability, causing chromosomal aberrations, including telomeric defects, similar to those observed in Su(var)205 mutants. In somatic cells, we observed that dXNP and dAdd1 participate in the silencing of the telomeric HTT array of retrotransposons, preventing anomalous retrotransposon transcription and integration. Furthermore, the lack of dAdd1 results in the loss of HP1a from the telomeric regions without affecting other chromosomal HP1a binding sites; mutations in dxnp also affected HP1a localization but not at all telomeres, suggesting a specialized role for dAdd1 and dXNP proteins in locating HP1a at the tips of the chromosomes. These results place dAdd1 as an essential regulator of HP1a localization and function in the telomere heterochromatic domain.

This is an updated version of the Cochrane Review published in the Cochrane Library 2011, Issue 12.The majority of people with epilepsy have a good prognosis, but up to 30% of people continue to have seizures despite several regimens of antiepileptic drugs. In this review, we summarized the current evidence regarding eslicarbazepine acetate (ESL) when used as an add-on treatment for drug-resistant partial epilepsy. To evaluate the efficacy and tolerability of ESL when used as an add-on treatment for people with drug-resistant partial epilepsy. The searches for the original review were run in November 2011. Subsequently, we searched the Cochrane Epilepsy Group Specialized Register (6 December 2016), the Cochrane Central Register of Controlled Trials (CENTRAL 2016, Issue 11) and MEDLINE (1946 to 6 December 2016). There were no language restrictions. We reviewed the reference lists of retrieved studies to search for additional reports of relevant studies. We also contacted the manufacturers of ESL and experts in the field for information about any unpublished or ongoing studies. Randomized placebo controlled double-blind add-on trials of ESL in people with drug-resistant partial epilepsy. Two review authors independently selected trials for inclusion and extracted data. Outcomes investigated included 50% or greater reduction in seizure frequency, seizure freedom, treatment withdrawal, adverse effects, and drug interactions. Primary analyses were by intention to treat (ITT). The dose-response relationship was evaluated in regression models. We included five trials (1799 participants) rated at low risk of bias; all studies were funded by BIAL. The overall risk ratio (RR) with 95% confidence interval (CI) for 50% or greater reduction in seizure frequency was 1.71 (95% CI 1.42 to 2.05). Dose regression analysis showed evidence that ESL reduced seizure frequency with an increase in efficacy with increasing doses of ESL. ESL was significantly associated with seizure freedom

Personality traits and body weight: Evidence using sibling comparisons.

Kim, Jinho

2016-08-01

Past research has shown that personality traits relate to body weight, but this relationship may be confounded by unobserved family-level characteristics such as genetic endowments. The purpose of this study was to investigate whether the association between personality traits, as measured by the Big Five taxonomy, and body weight among young adults is spurious owing to shared family background. Participants were drawn from the full (n = 14,366) and family (n = 2813) samples of the National Longitudinal Study of Adolescent to Adult Health (Add Health). The study employed family-fixed effects to eliminate shared family background factors that might affect personality traits and body weight simultaneously. Among the Big Five personality traits, only conscientiousness showed a robust association with body weight, including body mass index (BMI) and obesity risk. These results were robust to adjustments for family-fixed effects, which indicates that the association between conscientiousness and body weight is generally not confounded by unobserved family-level characteristics shared by siblings. A one-standard-deviation increase in conscientiousness was associated with a decrease in BMI by 0.89 (equivalent to a 2.5 kg decrease in weight for an individual with an average height of the sample) and a 12% reduction in the probability of being obese. This study also found some suggestive evidence of gender and racial/ethnic differences. The association between conscientiousness and obesity was larger and statistically significant only for women, and conscientiousness was most strongly associated with obesity among Hispanic people. Conscientiousness is associated with decreased body weight net of unobserved background characteristics that are shared by siblings. The results suggest that interventions that develop personality traits may have "spillover effects"; in other words, they may also help reduce obesity. Copyright © 2016 Elsevier Ltd.

Add/drop filters based on SiC technology for optical interconnects

NASA Astrophysics Data System (ADS)

Vieira, M.; Vieira, M. A.; Louro, P.; Fantoni, A.; Silva, V.

2014-03-01

In this paper we demonstrate an add/drop filter based on SiC technology. Tailoring of the channel bandwidth and wavelength is experimentally demonstrated. The concept is extended to implement a 1 by 4 wavelength division multiplexer with channel separation in the visible range. The device consists of a p-i'(a-SiC:H)-n/p-i(a-Si:H)-n heterostructure. Several monochromatic pulsed lights, separately or in a polychromatic mixture illuminated the device. Independent tuning of each channel is performed by steady state violet bias superimposed either from the front and back sides. Results show that, front background enhances the light-to-dark sensitivity of the long and medium wavelength channels and quench strongly the others. Back violet background has the opposite behaviour. This nonlinearity provides the possibility for selective removal or addition of wavelengths. An optoelectronic model is presented and explains the light filtering properties of the add/drop filter, under different optical bias conditions.

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.

Essential hypertension (EH) is a complex disease in which physiological, environmental, and genetic factors are involved in its genesis. The genetic variant of the alpha-adducin gene (ADD1) has been described as a risk factor for EH, but with controversial results.The objective of this study was to evaluate the association of ADD1 (Gly460Trp) gene polymorphism with the EH risk in a population from Madeira Island.A case-control study with 1614 individuals of Caucasian origin was performed, including 817 individuals with EH and 797 controls. Cases and controls were matched for sex and age, by frequency-matching method. All participants collected blood for biochemical and genotypic analysis for the Gly460Trp polymorphism. We further investigated which variables were independently associated to EH, and, consequently, analyzed their interactions.In our study, we found a significant association between the ADD1 gene polymorphism and EH (odds ratio 2.484, P = .01). This association remained statistically significant after the multivariate analysis (odds ratio 2.548, P = .02).The ADD1 Gly460Trp gene polymorphism is significantly and independently associated with EH risk in our population. The knowledge of genetic polymorphisms associated with EH is of paramount importance because it leads to a better understanding of the etiology and pathophysiology of this pathology.

Addressing weight stigma in physiotherapy: Development of a theory-driven approach to (re)thinking weight-related interactions.

PubMed

Setchell, J; Gard, M; Jones, L; Watson, B M

2017-08-01

In this article, we propose a theory-driven approach to developing interventions for reducing weight stigma in physiotherapy and discuss the design and exploratory trial of such an intervention. Weight stigma has been identified in physiotherapists in empirical investigations. However, there has been little consideration of how this stigma might be addressed. We highlight Goffman's work on stigma that provides social and embodied understandings of stigma. Goffman's approach, however, is notably apolitical, ahistorical and lacks mechanisms for understanding power. We suggest that post-structuralist perspectives can provide insight into these areas. Drawing on these theories, we critically examine the literature on weight stigma reduction, finding that trials have largely been unsuccessful. We argue that this may be due to overly passive and simplistic intervention designs. As context-specific understandings are desirable, we examine the nature of physiotherapy to determine what might be relevant to (re)thinking weight in this profession. We then discuss the development of a multifactorial, active weight stigma intervention we trialed with eight physiotherapists. Supported by theory, the outcomes of the exploratory study suggest that physiotherapy-specific factors such as fostering professional reflexivity and improving understandings of stigma need to be incorporated into an active intervention that considers the complex determinants of weight stigma.

Efficacy and Safety of Saxagliptin as Add-On Therapy in Type 2 Diabetes

PubMed Central

Neumiller, Joshua J.

2014-01-01

In Brief Combination therapy for type 2 diabetes using agents with complementary mechanisms of action may improve glycemic control to a greater extent than monotherapy and allow the use of lower doses of antihyperglycemic medications. Dipeptidyl peptidase-4 inhibitors, including saxagliptin, are recommended as add-on therapy to metformin and as part of two- or three-drug combinations in patients not meeting individualized glycemic goals with metformin alone or as part of a dual-therapy regimen. This article reviews the efficacy and safety of saxagliptin as an add-on therapy to metformin, glyburide, a thiazolidinedione, or insulin (with or without metformin) and as a component of triple therapy with metformin and a sulfonylurea.

Prasuna, P Lakshmi; Sudhakar, TP

2015-01-01

Background: Atypical antipsychotic drugs are known to cause many side effects which include daytime drowsiness. So many add on drugs are tried to reduce the same. Materials and Methods: 72 patients who were on atypical antipsychotic drugs were randomly assigned to either Modafinil or placebo and were followed for a period of 12 weeks. Daytime drowsiness, was taken at baseline, week 3, and at week 12 by using VAS, EDD scales. Results: The results were analyzed and showed that the Modafinil add on therapy significantly reduced the daytime Drowsiness. Conclusions: Modafinil could be a potential candidate in selected group of patients to decrease some of the unwanted adverse events like daytime drowsiness produced by atypical antipsychotics.

Savant, Jonathan D.; Furth, Susan L.; Meyers, Kevin E.C.

2014-01-01

Background Arterial stiffness is a natural consequence of aging, accelerated in certain chronic conditions, and predictive of cardiovascular events in adults. Emerging research suggests the importance of arterial stiffness in pediatric populations. Methods There are different indices of arterial stiffness. The present manuscript focuses on carotid-femoral pulse wave velocity and pulse wave analysis, although other methodologies are discussed. Also reviewed are specific measurement considerations for pediatric populations and the literature describing arterial stiffness in children with certain chronic conditions (primary hypertension, obesity, diabetes, chronic kidney disease, hypercholesterolemia, genetic syndromes involving vasculopathy, and solid organ transplant recipients). Conclusions The measurement of arterial stiffness in children is feasible and, under controlled conditions, can give accurate information about the underlying state of the arteries. This potentially adds valuable information about the functionality of the cardiovascular system in children with a variety of chronic diseases well beyond that of the brachial artery blood pressure.

Consideration of Materials for Aircraft Brakes

NASA Technical Reports Server (NTRS)

Peterson, M. B.; Ho, T.

1972-01-01

An exploratory investigation was conducted concerning materials and their properties for use in aircraft brakes. Primary consideration was given to the heat dissipation and the frictional behavior of materials. Used brake pads and rotors were analyzed as part of the investigation. A simple analysis was conducted in order to determine the most significant factors which affect surface temperatures. It was found that where size and weight restrictions are necessary, the specific heat of the material, and maintaining uniform contact area are the most important factors. A criterion was suggested for optimum sizing of the brake disks. Bench friction tests were run with brake materials. It was found that there is considerable friction variation due to the formation and removal of surface oxide films. Other causes of friction variations are surface softening and melting. The friction behavior at high temperature was found to be more characteristic of the steel surface rather than the copper brake material. It is concluded that improved brake materials are feasible.

Development of 'Twazon': An Arabic App for Weight Loss.

Weight gain and its related illnesses have become a major public health issue across the world, with Saudi Arabia and other Gulf countries seeing dramatic increases in obesity and overweight, and yet there is very little information on how to intervene with this demographic due to cultural and linguistic barriers. As the use of smartphones and apps has also increased in the region, information communication technologies could be a cost-effective means of facilitating the delivery of behavior-modification interventions directly to the target population. Although there are existing apps that offer lifestyle-modification tools, they do not give consideration to the evidence-based practices for weight management. This offers an opportunity to create an Arabic language weight loss app that offers localized content and adheres to evidence-informed practices that are needed for effective weight loss. This paper describes the process of developing an Arabic weight loss app designed to facilitate the modification of key nutritional and physical activity behaviors among Saudi adults, while taking into consideration cultural norms. The development of the Twazon app involved: (1) reviewing all available Arabic weight loss apps and compared with evidence-based practices for weight loss, (2) conducting a qualitative study with overweight and obese Saudi women to ascertain their preferences, (3) selecting which behavioral change strategies and guidelines to be used in the app, (4) creating the Saudi Food Database, (5) deciding on graphic design for both iPhone operating system and Android platforms, including user interface, relational database, and programming code, and (6) testing the beta version of the app with health professionals and potential users. The Twazon app took 23 months to develop and included the compilation of an original Saudi Food database. Eight subjects gave feedback regarding the content validity and usability of the app and its features during a pilot

Ability to accurately estimate calories is important for weight management, yet few studies have investigated whether individuals can accurately estimate calories during exercise or in a meal. The objective of this study was to determine if accuracy of estimation of moderate or vigorous exercise energy expenditure and calories in food is associated with body weight class or weight loss status. Fifty-eight adults who were either normal weight (NW) or overweight (OW), and either attempting (WL) or not attempting weight loss (noWL), exercised on a treadmill at a moderate (60% HRmax) and a vigorous intensity (75% HRmax) for 25 min. Subsequently, participants estimated the number of calories they expended through exercise and created a meal that they believed to be calorically equivalent to the exercise energy expenditure. The mean difference between estimated and measured calories in exercise and food did not differ within or between groups after moderate exercise. After vigorous exercise, OW-noWL overestimated energy expenditure by 72% and overestimated the calories in their food by 37% (P < 0.05). OW-noWL also significantly overestimated exercise energy expenditure compared with all other groups (P < 0.05) and significantly overestimated calories in food compared with both WL groups (P < 0.05). However, among all groups, there was a considerable range of overestimation and underestimation (-280 to +702 kcal), as reflected by the large and statistically significant absolute error in calorie estimation of exercise and food. There was a wide range of underestimation and overestimation of calories during exercise and in a meal. Error in calorie estimation may be greater in overweight adults who are not attempting weight loss.

Experimental re-evaluation of flunarizine as add-on antiepileptic therapy.

PubMed

Thakur, Anamika; Sahai, A K; Thakur, J S

2011-04-01

Experimental studies have found several calcium channel blockers with anticonvulsant property. Flunarizine is one of the most potent calcium channel blockers, which has shown anticonvulsant effect against pentylenetetrazole (PTZ) and maximal electroshock (MES)-induced seizures. However, further experimental and clinical trials have shown varied results. We conducted a PTZ model experimental study to re-evaluate the potential of flunarizine for add-on therapy in the management of refractory epilepsy. Experiments were conducted in PTZ model involving Swiss strain mice. Doses producing seizures in 50% and 99% mice, i.e. CD(50) and CD(99) values of PTZ were obtained from the dose-response study. Animals received graded, single dose of sodium valproate (100-300 mg/kg), lamotrigine (3-12 mg/kg) and flunarizine (5-20 mg/kg), and then each group of mice was injected with CD(99) dose of PTZ (65mg/kg i.p.). Another group of mice received single ED(50) dose (dose producing seizure protection in 50% mice) of sodium valproate and flunarizine separately in left and right side of abdomen. Results were analysed by Kruskal-Wallis ANOVA on Ranks test. As compared to control, sodium valproate at 250 mg/kg and 300 mg/kg produced statistical significant seizure protection. At none of the pre-treatment dose levels of lamotrigine, the seizure score with PTZ differed significantly from that observed in the vehicle-treated group. Pre-treatment with flunarizine demonstrated dose-dependent decrease in the seizure score to PTZ administration. As compared to control group, flunarizine at 20 mg/kg produced statistical significant seizure protection. As combined use of sodium valproate and flunarizine has shown significant seizure protection in PTZ model, flunarizine has a potential for add-on therapy in refractory cases of partial seizures. It is therefore, we conclude that further experimental studies and multicenter clinical trials involving large sample size are needed to establish

Monotherapy with pegylated interferon-α (Peg-IFNα) or the nucleos(t)ide analogs (NA) currently approved for treating chronic hepatitis B (CHB) has limited efficacy. Studies on the combination of Peg-IFNα/NA have shown conflicting results. We investigated whether sequentially adding on Peg-IFNα to tenofovir enhances serological response rates. Treatment-naïve, hepatitis B envelope antigen (HBeAg)-positive CHB patients with moderately elevated alanine aminotransferase (ALT; 48-200 IU/mL) were started on tenofovir (300 mg/day) and enrolled at week 12 in a 1:1 ratio to either receive Peg-IFNα2b add-on (1.5 μg/kg/week) from week 12 to 36 (n = 53) or continue tenofovir monotherapy (n = 53). Both treatment arms received tenofovir consolidation therapy until week 72. The primary end-point was HBeAg loss at week 72. At week 72, the rate of HBeAg loss was higher in the Peg-IFNα2b add-on group (35.8%) compared to the tenofovir monotherapy group (17%) (P = 0.028; odds ratio, 2.73, 95% confidence interval, 1.09-6.79), and considerably higher in patients with a baseline hepatitis B virus (HBV)-DNA level >6 log IU/mL (32.6% vs 11.4%; P = 0.021). Rates of HBV-DNA loss (77.4% vs 71.7%; P = 0.51), ALT normalization (62.3% vs 52.8%; P = 0.32), and sustained virologic response (20.8% vs 11.3%; P = 0.18) at week 72 were comparable between the two groups. Significantly more patients in the add-on group had >3 log HBV-DNA reduction at week 36 (92.5% vs 66%; P = 0.001). Four patients treated with Peg-IFNα2b add-on achieved hepatitis B surface antigen (HBsAg) loss compared with one patient receiving tenofovir monotherapy. Decline of HBV-DNA of >2 log at week 4 led to higher HBeAg loss at week 72, independent of treatment arm. No patient had treatment-related adverse effects requiring treatment discontinuation. Twenty-four weeks of Peg-IFNα2b as an add-on sequential regimen to tenofovir is safe and resulted in greater loss of HBeAg and HBs

We have studied a patient with clinical Down syndrome (DS) who has a mosaic 46, XX/46, XX, 21p+ karyotype. The patient was born at 39 weeks of gestation with a birth weight of 3,025 g to healthy parents. At age 2 months, she was diagnosed clinically to have DS; she had flat facies, upslanted palpebral fissures, epicanthal folds, telecanthus, flat nasal bridge, abnormal dentition, malformed ears, short neck, short fingers, clinodactyly with single flexion crease of the fifth fingers, hyperextension of joints, pes planus, distal axial triradii, and bilateral tibial arch patterns. Chromosome analysis showed mosaicism consisting of a normalmore » 46,XX cell line and a line with a 21p+ chromosome, the final karyotype being mos46,XX[57]/46,XX,add(21)(p11)[43]. Although the origin of an additional segment on chromosome 21 was not identified with conventional banding analyses, it was suspected to represent partial trisomy 21 on the basis of clinical manifestations. 6 refs., 2 figs.« less

Although the scientific research surrounding pharmacogenomics (PGx) has been relatively plentiful, the ethical research concerning this discipline has developed rather conservatively. Following investigation of the ethical, legal and social issues (ELSI) of PGx research, as well as consulting with key stakeholders, we identified six outstanding ethical issues raised by the informed consent process in PGx research: (1) scope of consent; (2) consent to 'add-on' studies; (3) protection of personal information; (4) commercialization; (5) data sharing; and (6) potential risks stemming from population-based research. In discussing these six areas as well as offering specific considerations, this article offers a solid base from which future practical guidelines for informed consent in PGx research can be constructed. As such, this effort works toward filling the ELSI gap and provides ethical support to the numerous PGx projects undertaken by researchers every year.

Abstract Background: To investigate whether saxagliptin add-on therapy to continuous subcutaneous insulin infusion (CSII) further improve blood glycemic control than CSII therapy in patients with newly diagnosed type 2 diabetes (T2D). Methods: This was a single-center, randomized, control, open-labeled trial. Newly diagnosed T2D patients were recruited between February 2014 and December 2015. Subjects were divided into saxagliptin add-on therapy to CSII group (n = 31) and CSII therapy group (n = 38). The treatment was maintained for 4 weeks. Oral glucose tolerance test was performed at baseline. Serum samples were obtained before and 30 and 120 minutes after oral administration for glucose, insulin, and C-peptide determination. Continuous glucose monitoring (CGM) was performed before and endpoint. Results: A total of 69 subjects were admitted. After 4-week therapy, CGM data showed that patients with saxagliptin add-on therapy exhibited further improvement of mean amplitude glycemic excursion (MAGE), the incremental area under curve of plasma glucose >7.8 and 10 mmol/L compared with that of control group. In addition, the hourly mean blood glucose concentrations, especially between 0000 and 0600 in patient with saxagliptin add-on therapy, were significantly lower compared with that of the control patients. Furthermore, patients in saxagliptin add-on group needed lower insulin dose to maintain euglycemic control. In addition, severe hypoglycemic episode was not observed from any group. Conclusion: Saxagliptin add-on therapy to insulin had the ability of further improve blood glycemic controlling, with lower insulin dose required by patients with T2D to maintain euglycemic controlling.

Background A variety of physician and patient characteristics may influence whether weight loss counseling occurs in primary care encounters. Objectives This study utilized a cross-sectional survey of primary care patients, which examined patient characteristics, physician characteristics, and characteristics of the physician-patient relationship associated with weight loss counseling and recommendations provided by physicians. Participants Participants (N=143, mean age=46.8 years, mean BMI=36.9 kg/m2, 65% Caucasian) were overweight and obese primary care patients participating in a managed care weight loss program. Measures Participants completed self-report surveys in the clinic prior to the initial weight loss session. Surveys included items assessing demographic/background characteristics, weight, height, and a health care questionnaire evaluating whether their physician had recommended weight loss, the frequency of their physicians’ weight loss counseling, and whether their physician had referred them for obesity treatment. Results Patient BMI and physician sex were most consistently associated with physicians’ weight loss counseling practices. Patients seen by female physicians were more likely to be told that they should lose weight, received more frequent obesity counseling, and were more likely to have been referred for obesity treatment by their physician. Length and frequency of physician-patient contacts were unrelated to the likelihood of counseling. Conclusions These findings add to previous evidence suggesting possible differences in the weight loss counseling practices of male and female physicians, although further research is needed to understand this potential difference between physicians.

Bove, Caron F.; Sobal, Jeffery

2011-01-01

This investigation uncovered processes underlying the dynamics of body weight and body image among individuals involved in nascent heterosexual marital relationships in Upstate New York. In-depth, semi-structured qualitative interviews conducted with 34 informants, 20 women and 14 men, just prior to marriage and again one year later were used to explore continuity and change in cognitive, affective, and behavioral factors relating to body weight and body image at the time of marriage, an important transition in the life course. Three major conceptual themes operated in the process of developing and enacting informants’ body weight relationships with their partner: weight relevance, weight comparisons, and weight talk. Weight relevance encompassed the changing significance of weight during early marriage and included attracting and capturing a mate, relaxing about weight, living healthily, and concentrating on weight. Weight comparisons between partners involved weight relativism, weight competition, weight envy, and weight role models. Weight talk employed pragmatic talk, active and passive reassurance, and complaining and critiquing criticism. Concepts emerging from this investigation may be useful in designing future studies of and approaches to managing body weight in adulthood. PMID:21864601

Weight-based bullying is a prevalent problem among youth with overweight and obesity, but remains neglected in existing policy-level strategies to address youth bullying. Parental support is an influential catalyst motivating political will for policy decisions affecting youth, but has received limited research attention. To assess levels of, and predictors of, parental support for school-based policies and state/federal legal measures to address weight-based bullying in 2014 and 2015. Identical online questionnaires were completed by two independent national samples of parents in 2014 and 2015 (N = 1804). Parental support for all policy actions was high (at least 81%) and significantly increased from 2014 to 2015 for legal measures that would a) require state anti-bullying laws to add protections against weight-based bullying, and b) enact a federal anti-bullying law that includes weight-based bullying. These findings can inform policy discourse about remedies for youth bullying, and suggest that parental support for improved legal protections against weight-based bullying is present, consistent, and strong. © 2016 World Obesity Federation.

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.

Colorectal adenomas are known as precursors for the majority of colorectal carcinomas. While weight gain during adulthood has been identified as a risk factor for colorectal cancer, the association is less clear for colorectal adenomas. We conducted a systematic review and meta-analysis to quantify the evidence on this association. We searched Medline up to September 2016 to identify observational (prospective, cross-sectional and retrospective) studies on weight gain during adulthood and colorectal adenoma occurrence and recurrence. We conducted meta-analysis on high weight gain versus stable weight, linear and non-linear dose-response meta-analyses to analyze the association. Summary odds ratios (OR) and 95% confidence intervals (95% CI) were estimated using a random effects model. For colorectal adenoma occurrence, the summary OR was 1.39 (95% CI: 1.17-1.65; I2: 43%, N = 9 studies, cases = 5507) comparing high (midpoint: 17.4 kg) versus stable weight gain during adulthood and with each 5 kg weight gain the odds increased by 7% (2%-11%; I2: 65%, N = 7 studies). Although there was indication of non-linearity (Pnon-linearity < 0.001) there was an increased odds of colorectal adenoma throughout the whole range of weight gain. Three studies were identified investigating the association between weight gain and colorectal adenoma recurrence and data were limited to draw firm conclusions. Even a small amount of adult weight gain was related to a higher odds of colorectal adenoma occurrence. Our findings add to the benefits of weight control in adulthood regarding colorectal adenoma occurrence, which might be relevant for early prevention of colorectal cancer. © The Author 2017.

Roflumilast is a recently marketed drug, indicated for maintenance treatment of severe chronic obstructive pulmonary disease associated with chronic bronchitis in adult patients with a history of frequent exacerbations as add on to bronchodilator treatment. The safety data of this drug have always been subjected to controversy and concerns. The Food and Drug Administration rejected the drug after the first evaluation, asking the company to clarify the adverse reactions during the investigation process, the European Medicines Agency approved the drug including a Risk Management Plan, designed to promote a safe use of the drug. During the first months after the marketing process, the Spanish Pharmacovigilance System has already been acquainted of several adverse events notifications; therefore, these patients may be closely monitored, mainly because of digestive and psychiatric disorders. Here we report the case of a female patient who showed a serious digestive clinical profile and a severe weight loss, more than 25% of her initial weight, when a treatment with roflumilast was started. The suspicion of a side effect as the cause of the reported clinical profile and its resolution required 3 hospital admissions. Copyright © 2013 Elsevier España, S.L. All rights reserved.

Biology of obesity and weight regain: Implications for clinical practice.

PubMed

Rogge, Mary Madeline; Gautam, Bibha

2017-10-01

Weight loss is recommended as first-line therapy for many chronic illnesses, including obesity. Most patients who do successfully lose weight are unable to maintain their reduced weight. Recent research findings are reviewed and synthesized to explain the biology of obesity, adaptation to weight loss, and weight regain. Weight regain is a common consequence of successful weight loss. Current obesity management strategies fail to take into consideration the underlying genetic and environmental causes of obesity. Available treatment modalities create a negative energy balance that stimulates integrated, persistent neurologic, endocrine, muscle, and adipose tissue adaptation to restore body weight and fat mass, independent of lifestyle changes. Understanding the pathophysiology of obesity and weight loss alters nurse practitioners' responsibilities in caring for patients with obesity. They are responsible for expanding assessment and intervention strategies and offering people with obesity realistic expectations for weight loss and regain. They are obligated to explain weight regain when it occurs to minimize patient frustration. Nurse practitioners have the opportunity to adopt new approaches to patient advocacy, especially in the areas of public policy to improve diagnostic tools and adjunctive therapy for people with obesity. ©2017 American Association of Nurse Practitioners.

Threepak, T; Mitatha, S; Yupapin, P P

2011-12-01

A novel design of all-optical logic device is proposed. An all-optical logic device system composes of an optical intensity switch and add/drop filter. The intensity switch is formed to switch signal by using the relationship between refraction angle and signal intensity. In operation, two input signals are coupled into one with some coupling loss and attenuation, in which the combination of add/drop with intensity switch produces the optical logic gate. The advantage is that the proposed device can operate the high speed logic function. Moreover, it uses low power consumption. Furthermore, by using the extremely small component, this design can be put into a single chip. Finally, we have successfully produced the all-optical logic gate that can generate the accurate AND and NOT operation results.

Multi-objective optimization for generating a weighted multi-model ensemble

NASA Astrophysics Data System (ADS)

Lee, H.

2017-12-01

Many studies have demonstrated that multi-model ensembles generally show better skill than each ensemble member. When generating weighted multi-model ensembles, the first step is measuring the performance of individual model simulations using observations. There is a consensus on the assignment of weighting factors based on a single evaluation metric. When considering only one evaluation metric, the weighting factor for each model is proportional to a performance score or inversely proportional to an error for the model. While this conventional approach can provide appropriate combinations of multiple models, the approach confronts a big challenge when there are multiple metrics under consideration. When considering multiple evaluation metrics, it is obvious that a simple averaging of multiple performance scores or model ranks does not address the trade-off problem between conflicting metrics. So far, there seems to be no best method to generate weighted multi-model ensembles based on multiple performance metrics. The current study applies the multi-objective optimization, a mathematical process that provides a set of optimal trade-off solutions based on a range of evaluation metrics, to combining multiple performance metrics for the global climate models and their dynamically downscaled regional climate simulations over North America and generating a weighted multi-model ensemble. NASA satellite data and the Regional Climate Model Evaluation System (RCMES) software toolkit are used for assessment of the climate simulations. Overall, the performance of each model differs markedly with strong seasonal dependence. Because of the considerable variability across the climate simulations, it is important to evaluate models systematically and make future projections by assigning optimized weighting factors to the models with relatively good performance. Our results indicate that the optimally weighted multi-model ensemble always shows better performance than an arithmetic

Considerations for protein intake in managing weight loss in athletes.

PubMed

Murphy, Caoileann H; Hector, Amy J; Phillips, Stuart M

2015-01-01

A large body of evidence now shows that higher protein intakes (2-3 times the protein Recommended Dietary Allowance (RDA) of 0.8 g/kg/d) during periods of energy restriction can enhance fat-free mass (FFM) preservation, particularly when combined with exercise. The mechanisms underpinning the FFM-sparing effect of higher protein diets remain to be fully elucidated but may relate to the maintenance of the anabolic sensitivity of skeletal muscle to protein ingestion. From a practical point of view, athletes aiming to reduce fat mass and preserve FFM should be advised to consume protein intakes in the range of ∼1.8-2.7 g kg(-1) d(-1) (or ∼2.3-3.1 g kg(-1) FFM) in combination with a moderate energy deficit (-500 kcal) and the performance of some form of resistance exercise. The target level of protein intake within this recommended range requires consideration of a number of case-specific factors including the athlete's body composition, habitual protein intake and broader nutrition goals. Athletes should focus on consuming high-quality protein sources, aiming to consume protein feedings evenly spaced throughout the day. Post-exercise consumption of 0.25-0.3 g protein meal(-1) from protein sources with high leucine content and rapid digestion kinetics (i.e. whey protein) is recommended to optimise exercise-induced muscle protein synthesis. When protein is consumed as part of a mixed macronutrient meal and/or before bed slightly higher protein doses may be optimal.

Medicalization, ambivalence and social control: mothers' descriptions of educators and ADD/ADHD.

PubMed

Malacrida, Claudia

2004-01-01

Conrad notes that non-medical personnel often accomplish the routine, everyday work of medicalization. This is particularly so in the case of Attention Deficit (Hyperactivity) Disorder, where teachers, special educators and school psychologists identify, assess and administer medication to 'problematic' children. Drawing on data from interviews with Canadian and British mothers of ADD/ADHD children, this article explores mothers' perceptions of educators' roles in medicalizing children who are different, comparing medicalization in two divergent sites. In Canada, where ADD/ADHD is a highly medicalized phenomenon, and teachers have few alternative forms of social control available to them in classrooms, it appears that educators are prepared to identify problem children and press for medical treatment with remarkable vigor. In Britain, where medicalization remains incomplete, and where teachers and special educators have more stringent alternative forms of social control available to them, educators were often described as gatekeepers who will refuse the label or to administer medication.

Abstract Background: Drug intensification is often required for patients with type 2 diabetes mellitus on stable metformin therapy. Among the potential candidates for a combination therapy, sodium-glucose transporter-2 (SGLT2) inhibitors have shown promising outcomes. This meta-analysis was performed to compare the efficacy and safety of SGLT2 inhibitors with non-SGLT2 combinations as add-on treatment to metformin. Methods: Literature search was carried out in multiple electronic databases for the acquisition of relevant randomized controlled trials (RCTs) by following a priori eligibility criteria. After the assessment of quality of the included RCTs, meta-analyses of mean differences or odds ratios (OR) were performed to achieve overall effect sizes of the changes from baseline in selected efficacy and safety endpoints reported in the individual studies. Between-studies heterogeneity was estimated with between-studies statistical heterogeneity (I2) index. Results: Six RCTs fulfilled the eligibility criteria. SGLT2 inhibitors as add-on to metformin treatment reduced % HbA1c significantly more than non-SGLT2 combinations after 52 weeks (P = .002) as well as after 104 weeks (P < .00001). Among other endpoints, SGLT2 inhibitors also reduced fasting plasma glucose levels, body weight, systolic, and diastolic blood pressures after 52 weeks and 104 weeks significantly (P < .00001) more than non-SGLT2 combinations. Incidence of hypoglycemia was significantly lower (P = .02) but incidence of suspected or confirmed genital tract infections was significantly higher (P < .00001) in SGLT2 inhibitors treated in comparison with non-SGLT2 combinations. Conclusion: As add-on to metformin treatment, SGLT2 inhibitors are found significantly more efficacious than non-SGLT2 inhibitor combinations in the management of type 2 diabetes mellitus, although, SGLT2 inhibitor therapy is associated with significantly higher incidence of suspected or confirmed genital tract

To estimate the long-term cost-effectiveness of exenatide twice daily vs insulin glargine once daily as add-on therapy to oral antidiabetic agents (OADs) for Chinese patients with type 2 diabetes (T2DM). The Cardiff Diabetes Model was used to simulate disease progression and estimate the long-term effects of exenatide twice daily vs insulin glargine once daily. Patient profiles and treatment effects required for the model were obtained from literature reviews (English and Chinese databases) and from a meta-analysis of 8 randomized controlled trials comparing exenatide twice daily with insulin glargine once daily add-on to OADs for T2DM in China. Medical expenditure data were collected from 639 patients with T2DM (aged ≥18 years) with and without complications incurred between January 1, 2014 and December 31, 2015 from claims databases in Shandong, China. Costs (2014 Chinese Yuan [¥]) and benefits were estimated, from the payers' perspective, over 40 years at a discount rate of 3%. A series of sensitivity analyses were performed. Patients on exenatide twice daily + OAD had a lower predicted incidence of most cardiovascular and hypoglycaemic events and lower total costs compared with those on insulin glargine once daily + OAD. A greater number of quality-adjusted life years (QALYs; 1.94) at a cost saving of ¥117 706 gained was associated with exenatide twice daily vs insulin glargine once daily. (i.e. cost saving of ¥60 764/QALY) per patient. In Chinese patients with T2DM inadequately controlled by OADs, exenatide twice daily is a cost-effective add-on therapy alternative to insulin glargine once daily, and may address the problem of an excess of medical needs resulting from weight gain and hypoglycaemia in T2DM treatment. © 2017 John Wiley & Sons Ltd.

Patients stabilized on open-label metformin and saxagliptin 5 mg/day for 8-16 weeks were randomized to placebo or dapagliflozin 10 mg/day plus open-label saxagliptin plus metformin for 52 weeks. Changes from baseline to week 52 were greater with dapagliflozin versus placebo in A1C (-0.74% vs. 0.07%), FPG (-27 vs. 10 mg/dL) and BW (-2.1 vs. -0.4 kg). More patients achieved A1C <7% with dapagliflozin (29.4%) versus placebo (12.6%). Adverse events were similar with dapagliflozin (66%) and placebo (71%), and hypoglycaemia was rare (≤2%). Genital infections occurred more often with dapagliflozin (6%) than with placebo (1%); frequency of urinary tract infections was similar between the two groups (9% vs. 10%). Triple therapy with dapagliflozin add-on to saxagliptin plus metformin is a durable, effective and well-tolerated intervention for the treatment of T2D. © 2016 John Wiley & Sons Ltd.

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

The Sloan Digital Sky Survey Stripe 82 Imaging Data: Depth-Optimized Co-adds Over 300 deg$^2$ in Five Filters

DOE Office of Scientific and Technical Information (OSTI.GOV)

Jiang, Linhua; Fan, Xiaohui; Bian, Fuyan

We present and release co-added images of the Sloan Digital Sky Survey (SDSS) Stripe 82. Stripe 82 covers an area of ~300 deg(2) on the celestial equator, and has been repeatedly scanned 70-90 times in the ugriz bands by the SDSS imaging survey. By making use of all available data in the SDSS archive, our co-added images are optimized for depth. Input single-epoch frames were properly processed and weighted based on seeing, sky transparency, and background noise before co-addition. The resultant products are co-added science images and their associated weight images that record relative weights at individual pixels. The depths of themore » co-adds, measured as the 5σ detection limits of the aperture (3.''2 diameter) magnitudes for point sources, are roughly 23.9, 25.1, 24.6, 24.1, and 22.8 AB magnitudes in the five bands, respectively. They are 1.9-2.2 mag deeper than the best SDSS single-epoch data. The co-added images have good image quality, with an average point-spread function FWHM of ~1'' in the r, i, and z bands. We also release object catalogs that were made with SExtractor. These co-added products have many potential uses for studies of galaxies, quasars, and Galactic structure. We further present and release near-IR J-band images that cover ~90 deg(2) of Stripe 82. These images were obtained using the NEWFIRM camera on the NOAO 4 m Mayall telescope, and have a depth of about 20.0-20.5 Vega magnitudes (also 5σ detection limits for point sources).« less

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.

The thinner the better: self-esteem and low body weight in anorexia nervosa.

The aim of the present study was to examine the associations between self-esteem, motive satisfaction, and body weight in acute (acAN) and recovered (recAN) inpatients with anorexia nervosa (AN) and in healthy controls. Both acAN and recAN showed lower levels of self-esteem as compared with healthy controls but did not differ from each other. In acAN, decreased body weight was associated with increased self-esteem. Satisfaction of an achievement motive but not satisfaction of a superiority motive mediated this association. No such correlations could be observed in the other groups. This is the first study to show an often assumed association between decreased body weight and increased self-esteem in AN patients. These preliminary results strengthen the assumption that low body weight may foster self-esteem in patients with acAN, mainly through the satisfaction of an achievement motive. Self-esteem should be focused very early in the treatment of AN since weight gain may deprive the patient of an important source of self-esteem. Treatment interventions should be attuned to underlying motives of threatened self-esteem; in AN patients, the enhancement of self-esteem via weight loss seems to be rather fuelled by the satisfaction of an achievement motive than by the satisfaction of a superiority motive. Specific trainings to improve self-esteem in AN patients seem to be promising as an add-on to regular treatment. Copyright © 2012 John Wiley & Sons, Ltd.

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.

Nutritional guidelines involving the feeding of very low birth weight babies (VLBW) recommend addition of Human Milk Fortifiers to breast milk. Owing to financial constraints, it is a practice in low- and middle-income countries (LMIC) to add coconut oil to aid better weight gain. There are inadequate data on improvement of growth parameters with oral coconut oil supplementation of breast milk. In this randomized controlled trial, we measured growth parameters and body composition of 60 babies who received either breast milk with coconut oil or breast milk alone. Randomization was stratified according to intrauterine growth appropriate for gestational age (n = 30) and small for gestational age (n = 30). There was no difference in weight gain between the two groups. The weight gain velocity was 15 ± 3.6 and 14.4 ± 3.4 g/kg/day (p value = 0.49) in the breast milk alone and in the breast milk with coconut oil group, respectively. There was no difference in increase in head circumference and length. Triceps skinfold thickness (n = 56) was similar in both groups, but subscapular skinfold thickness was significantly more in the coconut oil group. Total body fat percentage did not differ between the groups (25.2 ± 4.3 vs. 25.5 ± 4.3%, p = 0.79). Oral supplementation of coconut oil along with breast milk did not increase growth parameters or result in change in body composition in very low birth weight (VLBW) babies.

Montoya, L. C.; Steers, L. L.

1974-01-01

Aerodynamic drag tests were performed on a conventional cab-over-engine tractor with a 45-foot trailer and five commercially available or potentially available add-on devices using the coast-down method. The tests ranged in velocity from approximately 30 miles per hour to 65 miles per hour and included some flow visualization. A smooth, level runway at Edwards Air Force Base was used for the tests, and deceleration measurements were taken with both accelerometers and stopwatches. An evaluation of the drag reduction results obtained with each of the five add-on devices is presented.

Using patient lists to add value to integrated data repositories.

Patient lists are project-specific sets of patients that can be queried in integrated data repositories (IDR's). By allowing a set of patients to be an addition to the qualifying conditions of a query, returned results will refer to, and only to, that set of patients. We report a variety of use cases for such lists, including: restricting retrospective chart review to a defined set of patients; following a set of patients for practice management purposes; distributing "honest-brokered" (deidentified) data; adding phenotypes to biosamples; and enhancing the content of study or registry data. Among the capabilities needed to implement patient lists in an IDR are: capture of patient identifiers from a query and feedback of these into the IDR; the existence of a permanent internal identifier in the IDR that is mappable to external identifiers; the ability to add queryable attributes to the IDR; the ability to merge data from multiple queries; and suitable control over user access and de-identification of results. We implemented patient lists in a custom IDR of our own design. We reviewed capabilities of other published IDRs for focusing on sets of patients. The widely used i2b2 IDR platform has various ways to address patient sets, and it could be modified to add the low-overhead version of patient lists that we describe. Copyright © 2014 Elsevier Inc.

The purpose of the study was to examine gender differences on the pharmacokinetics of ethanol. Sixty-eight healthy men and 64 healthy women with normal body mass indexes received between 0.79 and 0.95 g ethanol/kg body weight in the form of their choice after they had eaten a "typical" breakfast. The aimed concentration for both genders was a blood alcohol concentration C(0) of 0.104 g/dl. Blood samples in the elimination phase were taken in 10- to 20-min intervals beginning after completion of absorption. The maximum blood ethanol concentration was 0.0819+/-0.0184 g/dl for women and 0.0841+/-0.0155 g/dl for men. The hourly ethanol elimination rate, calculated over a linear function, in blood of 0.0179+/-0.0030 g/dl/h in women was significantly higher than the 0.0159+/-0.0029 g/dl/h for men (P<.0001). In relation to the liver weight, the hourly elimination rates were 5.008+/-0.678 g/kg liver/h for women and 4.854+/-0.659 g/kg liver/h for men, and were not statistically significant. The different liver masses as calculated in relation to the distribution volume account for the differing ethanol elimination rates between men and women.

Shape and weight concerns among overweight pre-adolescents heighten risk for eating disorders and weight gain. Treatment and prevention efforts require consideration of psychosocial factors that co-occur with these concerns. This study involved 200 overweight pre-adolescents, aged 7–12 years (M age = 9.8; SD = 1.4), presenting for family-based weight control treatment. Hierarchical regression was used to examine the influence of pre-adolescents’ individual characteristics and social experiences, and their parents’ psychological symptoms, on shape and weight concerns as assessed by the Child Eating Disorder Examination. Findings revealed that higher levels of dietary restraint, greater feelings of loneliness, elevated experiences with weight-related teasing, and higher levels of parents’ eating disorder symptoms predicted higher shape and weight concerns among overweight pre-adolescents. Interventions addressing overweight pre-adolescents’ disordered eating behaviors and social functioning, as well as their parents’ disordered eating behaviors and attitudes, may be indicated for those endorsing shape and weight concerns.

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.

This study assessed the efficacy and safety of canagliflozin, a sodium-glucose cotransporter 2 inhibitor, as add-on to insulin in adults with type 1 diabetes. This 18-week, double-blind, phase 2 study randomized 351 patients (HbA1c 7.0-9.0% [53-75 mmol/mol]) on multiple daily insulin injections or continuous subcutaneous insulin infusion to canagliflozin 100 or 300 mg or placebo. The primary end point was the proportion of patients achieving at week 18 both HbA1c reduction from baseline of ≥0.4% (≥4.4 mmol/mol) and no increase in body weight. Other end points included changes in HbA1c, body weight, and insulin dose, as well as hypoglycemia incidence. Safety was assessed by adverse event (AE) reports. More patients had both HbA1c reduction ≥0.4% and no increase in body weight with canagliflozin 100 and 300 mg versus placebo at week 18 (36.9%, 41.4%, 14.5%, respectively; P < 0.001). Both canagliflozin doses provided reductions in HbA1c, body weight, and insulin dose versus placebo over 18 weeks. The incidence of hypoglycemia was similar across groups; severe hypoglycemia rates were low (1.7-6.8%). Overall incidence of AEs was 55.6%, 67.5%, and 54.7% with canagliflozin 100 and 300 mg and placebo; discontinuation rates were low (0.9-1.3%). Increased incidence of ketone-related AEs (5.1%, 9.4%, 0%), including the specific AE of diabetic ketoacidosis (DKA) (4.3%, 6.0%, 0%), was seen with canagliflozin 100 and 300 mg versus placebo. Canagliflozin provided reductions in HbA1c, body weight, and insulin dose with no increase in hypoglycemia, but increased rates of ketone-related AEs, including DKA, in adults with type 1 diabetes inadequately controlled with insulin. © 2015 by the American Diabetes Association.

DIFFUSION-WEIGHTED IMAGING OF THE LIVER: TECHNIQUES AND APPLICATIONS

PubMed Central

Lewis, Sara; Dyvorne, Hadrien; Cui, Yong; Taouli, Bachir

2014-01-01

SYNOPSIS Diffusion weighted MRI (DWI) is a technique that assesses the cellularity, tortuosity of the extracellular/extravascular space and cell membrane density based upon differences in water proton mobility in tissues. The strength of the diffusion weighting is reflected by the b-value. DWI using several b-values enables quantification of the apparent diffusion coefficient (ADC). DWI is increasingly employed in liver imaging for multiple reasons: it can add useful qualitative and quantitative information to conventional imaging sequences, it is acquired relatively quickly, it is easily incorporated into existing clinical protocols, and it is a non-contrast technique. DWI is useful for focal liver lesion detection and characterization, for the assessment of post-treatment tumor response and for evaluation of diffuse liver disease. ADC quantification can be used to characterize lesions as cystic/necrotic or solid and for predicting tumor response to therapy. Advanced diffusion methods such as IVIM (intravoxel incoherent motion) may have potential for detection, staging and evaluation of the progression of liver fibrosis and for liver lesion characterization. The lack of standardization of DWI technique including choice of b-values and sequence parameters has somewhat limited its widespread adoption. PMID:25086935

Insatiable insecurity: maternal obesity as a risk factor for mother-child attachment and child weight.

PubMed

Childhood obesity has become a rising health problem, and because parental obesity is a basic risk factor for childhood obesity, biological factors have been especially considered in the complex etiology. Aspects of the family interaction, e.g., mother-child attachment, have not been the main focus. Our study tried to fill this gap by investigating whether there is a difference between children of obese and normal weight mothers in terms of mother-child attachment, and whether mother-child attachment predicts child's weight, in a sample of 31 obese and 31 normal weight mothers with children aged 19 to 58 months. Mother-child attachment was measured with the Attachment Q-Set. We found that (1) children of obese mothers showed a lower quality of mother-child attachment than children of normal weight mothers, which indicates that they are less likely to use their mothers as a secure base; (2) the attachment quality predicted child`s BMI percentile; and (3) the mother-child attachment adds incremental validity to the prediction of child's BMI beyond biological parameters (child's BMI birth percentile, BMI of the parents) and mother's relationship status. Implications of our findings are discussed.

The Situation Awareness Weighted Network (SAWN) model and method: Theory and application.

PubMed

Kalloniatis, Alexander; Ali, Irena; Neville, Timothy; La, Phuong; Macleod, Iain; Zuparic, Mathew; Kohn, Elizabeth

2017-05-01

We introduce a novel model and associated data collection method to examine how a distributed organisation of military staff who feed a Common Operating Picture (COP) generates Situation Awareness (SA), a critical component in organisational performance. The proposed empirically derived Situation Awareness Weighted Network (SAWN) model draws on two scientific models of SA, by Endsley involving perception, comprehension and projection, and by Stanton et al. positing that SA exists across a social and semantic network of people and information objects in activities connected across a set of tasks. The output of SAWN is a representation as a weighted semi-bipartite network of the interaction between people ('human nodes') and information artefacts such as documents and system displays ('product nodes'); link weights represent the Endsley levels of SA that individuals acquire from or provide to information objects and other individuals. The SAWN method is illustrated with aggregated empirical data from a case study of Australian military staff undertaking their work during two very different scenarios, during steady-state operations and in a crisis threat context. A key outcome of analysis of the weighted networks is that we are able to quantify flow of SA through an organisation as staff seek to "value-add" in the conduct of their work.

Infrared target tracking via weighted correlation filter

NASA Astrophysics Data System (ADS)

He, Yu-Jie; Li, Min; Zhang, JinLi; Yao, Jun-Ping

2015-11-01

Design of an effective target tracker is an important and challenging task for many applications due to multiple factors which can cause disturbance in infrared video sequences. In this paper, an infrared target tracking method under tracking by detection framework based on a weighted correlation filter is presented. This method consists of two parts: detection and filtering. For the detection stage, we propose a sequential detection method for the infrared target based on low-rank representation. For the filtering stage, a new multi-feature weighted function which fuses different target features is proposed, which takes the importance of the different regions into consideration. The weighted function is then incorporated into a correlation filter to compute a confidence map more accurately, in order to indicate the best target location based on the detection results obtained from the first stage. Extensive experimental results on different video sequences demonstrate that the proposed method performs favorably for detection and tracking compared with baseline methods in terms of efficiency and accuracy.

This work was aimed at reducing acoustic noise in diffusion-weighted MR imaging (DWI) that might reach acoustic noise levels of over 100 dB(A) in clinical practice. A diffusion-weighted readout-segmented echo-planar imaging (EPI) sequence was optimized for acoustic noise by utilizing small readout segment widths to obtain low gradient slew rates and amplitudes instead of faster k-space coverage. In addition, all other gradients were optimized for low slew rates. Volunteer and patient imaging experiments were conducted to demonstrate the feasibility of the method. Acoustic noise measurements were performed and analyzed for four different DWI measurement protocols at 1.5T and 3T. An acoustic noise reduction of up to 20 dB(A) was achieved, which corresponds to a fourfold reduction in acoustic perception. The image quality was preserved at the level of a standard single-shot (ss)-EPI sequence, with a 27-54% increase in scan time. The diffusion-weighted imaging technique proposed in this study allowed a substantial reduction in the level of acoustic noise compared to standard single-shot diffusion-weighted EPI. This is expected to afford considerably more patient comfort, but a larger study would be necessary to fully characterize the subjective changes in patient experience.

Physical activity has been shown to attenuate the association between overweight/obesity and deleterious cardiovascular health-related outcomes, with emerging work also taking the duration of overweight/obesity into consideration. No previous work, however, has explored the interrelationships between physical activity, obesity, and obesity duration in the context of cognitive task performance, which was the purpose of this study. Data from the 1999-2002 National Health and Nutrition Examination Survey were used (N = 2322 adults 60-85 yrs). Physical activity was assessed via self-report, with body mass index (BMI) directly measured. Participants were classified into one of eight mutually exclusive groups: (0) normal weight now and 10 years ago and active now (n = 195), (1) normal weight and 10 years ago and inactive now (n = 265), (2) normal weight now but not 10 years ago and active now (n = 46), (3) normal weight now but not 10 years ago and inactive now (n = 123), (4) overweight/obese now but not 10 years ago and active now (n = 117), (5) overweight/obese now but not 10 years ago and inactive now (n = 168), (6) overweight/obese now and 10 years ago and active now (n = 435), and (7) overweight/obese now and 10 years ago and inactive now (n = 973). The digit symbol substitution test (DSST) was employed to assess cognitive task performance. After adjustments, only individuals who were inactive (groups 1, 3, 5, and 7) had significantly lower cognitive task performance. Being inactive, regardless of weight classification and duration of overweight/obesity, was inversely associated with cognitive task performance in this national sample of older adults.

Weight maintenance as a tight rope walk - a Grounded Theory study.

Overweight and obesity are considerable public health problems internationally as well as in Sweden. The long-term results of obesity treatment are modest as reported by other studies. The importance of extending the focus to not only comprise obesity treatment but also prevention of weight gain is therefore being emphasized. However, despite the suggested change in focus there is still no consensus on how to prevent obesity or maintain weight. This study reports findings from a qualitative study focusing on attitudes, behaviors and strategies important for primary weight maintenance in a middle-aged population. In depth interviews were conducted with 23 maintainers and four slight gainers in Sweden. The interviews were transcribed and an analysis of weight maintenance was performed using Grounded Theory. Based on the informants' stories, describing attitudes, behaviors and strategies of importance for primary weight maintenance, a model illustrating the main findings, was constructed. Weight maintenance was seen as "a tightrope walk" and four strategies of significance for this "tightrope walk" were described as "to rely on heritage", "to find the joy", "to find the routine" and "to be in control". Eleven "ideal types" were included in the model to illustrate different ways of relating to the main strategies. These "ideal types" described more specific attitudes and behaviors such as; eating food that is both tasteful and nutritious, and choosing exercise that provides joy. However, other somewhat contradictory behaviors were also found such as; only eating nutritious food regardless of taste, and being physically active to control stress and emotions. This study show great variety with regards to attitudes, strategies and behaviors important for weight maintenance, and considerations need to be taken before putting the model into practice. However, the results from this study can be used within primary health care by enhancing the understanding of how people

Metabolic and other effects of pioglitazone as an add-on therapy to metformin in the treatment of polycystic ovary syndrome (PCOS).

PubMed

Valsamakis, Georgios; Lois, Kostas; Kumar, Sudhesh; Mastorakos, George

Insulin resistance is a key pathogenic defect of the clustered metabolic disturbances seen in polycystic ovary syndrome (PCOS). Metformin is an insulin sensitizer acting in the liver and the peripheral tissues that ameliorates the metabolic and reproductive defects in PCOS. In addition, pioglitazone is an insulin sensitizer used in diabetes mellitus type 2 (T2DM), improving insulin resistance (IR) in adipose tissue and muscles. In T2DM, these drugs are also used as a combined treatment due to their "add-on effect" on insulin resistance. Although the beneficial role of troglitazone (a member of the thiazolidinediones (TZDs) family) in PCOS has been shown in the past, currently only pioglitazone is available in the market. A few small randomized controlled trials have directly compared the effectiveness of pioglitazone in women with PCOS, while there are a limited number of small studies that support the beneficial metabolic add-on effect of pioglitazone on metformin-treated PCOS women as compared to metformin or pioglitazone monotherapy. These findings suggest a potentially promising role for combined pioglitazone/metformin treatment in the management of PCOS in metformin-resistant patients. In view of recent concerns regarding pioglitazone usage and its associated health risk, we aim to compare the pros and cons of each drug regarding their metabolic and other hormonal effects in women with PCOS and to explore the possible beneficial effect of combined therapy in certain cases, taking into consideration the teratogenic effect of pioglitazone. Finally, we discuss the need for a randomized controlled trial that will evaluate the metabolic and other hormonal effects of combined metformin/pioglitazone treatment in PCOS with selective treatment targets.

Behavioral therapy for weight loss in patients with schizophrenia.

PubMed

Ganguli, Rohan

2007-01-01

Compared with the general population, individuals with schizophrenia demonstrate an increased prevalence of obesity. While most antipsychotics are associated with weight gain, certain second-generation antipsychotics (SGAs) appear to be especially problematic. Weight gain and obesity are highly distressing to these patients, can reduce treatment adherence, and may increase the relative risk of serious medical conditions and all-cause premature mortality. The selection of an antipsychotic on the basis of its effectiveness and relative side effect profile is recognized as an important initial consideration in the treatment of schizophrenia. However, less is known regarding the efficacy of dietary, pharmacologic, and behavioral therapy in reducing antipsychotic-related weight gain and obesity. Behavioral therapy, in particular, is understudied, and there are relatively few controlled trials of its effectiveness in reducing SGA-induced weight gain. Although weight loss resulting from behavioral therapy has been observed mostly as a result of effective short-term interventions, controlled behavioral studies do exist to suggest that weight can be controlled long term. In addition, a small pilot study in patients with schizophrenia or schizoaffective disorder recently demonstrated that behavioral therapy that utilizes stepped interventions, involving body weight self-monitoring, diet, and exercise, can prevent weight gain in patients initiating treatment with SGAs. Additional studies of behavioral therapy for long-term weight control in patients with schizophrenia and other forms of severe mental illness are warranted.

THE SLOAN DIGITAL SKY SURVEY STRIPE 82 IMAGING DATA: DEPTH-OPTIMIZED CO-ADDS OVER 300 deg{sup 2} IN FIVE FILTERS

DOE Office of Scientific and Technical Information (OSTI.GOV)

Jiang, Linhua; Fan, Xiaohui; McGreer, Ian D.

We present and release co-added images of the Sloan Digital Sky Survey (SDSS) Stripe 82. Stripe 82 covers an area of ∼300 deg{sup 2} on the celestial equator, and has been repeatedly scanned 70-90 times in the ugriz bands by the SDSS imaging survey. By making use of all available data in the SDSS archive, our co-added images are optimized for depth. Input single-epoch frames were properly processed and weighted based on seeing, sky transparency, and background noise before co-addition. The resultant products are co-added science images and their associated weight images that record relative weights at individual pixels. Themore » depths of the co-adds, measured as the 5σ detection limits of the aperture (3.''2 diameter) magnitudes for point sources, are roughly 23.9, 25.1, 24.6, 24.1, and 22.8 AB magnitudes in the five bands, respectively. They are 1.9-2.2 mag deeper than the best SDSS single-epoch data. The co-added images have good image quality, with an average point-spread function FWHM of ∼1'' in the r, i, and z bands. We also release object catalogs that were made with SExtractor. These co-added products have many potential uses for studies of galaxies, quasars, and Galactic structure. We further present and release near-IR J-band images that cover ∼90 deg{sup 2} of Stripe 82. These images were obtained using the NEWFIRM camera on the NOAO 4 m Mayall telescope, and have a depth of about 20.0-20.5 Vega magnitudes (also 5σ detection limits for point sources)« less

Young Adults’ Attitudes and Perceptions of Obesity and Weight Management: Implications for Treatment Development

PubMed Central

Lanoye, Autumn; Gorin, Amy A.; LaRose, Jessica Gokee

2017-01-01

Young adults are underrepresented in standard behavioral weight loss trials, and evidence suggests that they differ from older adults on many weight related constructs. The aim of this review is to explore young adults’ attitudes toward obesity and weight management, with particular attention to those factors that may play a role in development of future treatment efforts. Both intrapersonal and interpersonal considerations unique to young adulthood are assessed; in addition, we examine young adults’ perceptions of specific weight-related behaviors such as dieting, physical activity, and self-weighing. Conclusions are consistent with other findings suggesting that weight management interventions should be adapted and designed specifically for this age group. PMID:26923688

A vehicle capable of performing the transfer of eight people to and from the Space Station Freedom is currently in the conceptual/preliminary design stages at the NASA Langley Research Center. Structural definition of this Personnel Launch System (PLS) and the considerations leading to it are described. Issues such as cost, technology level, human factors, and maintainability are used as guidelines for the structural definition. A synergistic design technique involving aerodynamics, performance, mission, packaging, and weights and sizing analyses is utilized to evaluate the structural design. A closed-loop design is achieved when the mission requirements are met by each previously mentioned analysis for a particular vehicle weight. Although satisfactory, the structural concept presented herein is not to be treated as a final answer, but one promising solution. An examination of alternative designs and more detailed analyses can be undertaken in order to identify design inadequacies and more efficient approaches.

Adjunctive antiepileptic drugs in adult epilepsy: how the first add-on could be the last.

PubMed

Cretin, Benjamin; Hirsch, Edouard

2010-05-01

In adult epilepsies, incomplete seizure control under monotherapy affects approximately 20-25% of patients with idiopathic generalized epilepsies (IGE) and approximately 20-40% of patients with epilepsies with focal seizures (FE). The choice of an adjunctive therapy is therefore a common event. Efficacy studies of add-on anti-epileptic drugs for adult epilepsies--approved since the early 1990s until 2008--were reviewed. An exception was made for valproate. Efficacy studies give important clues for add-on drug choice but--beyond this--we encourage physicians to consider other parameters, especially co-morbidity(ies) and special situation(s). According to clinical and pharmacological data, an original, practical approach is proposed, by which decisions are based on three main criteria, which aim to optimize patients' seizure control and quality of life. The need for drugs that act not only on 'ictogenesis' but also on 'epileptogenesis' is also discussed briefly. Given the increasing disposal of anti-epileptic drugs, the choice of an add-on therapy appears to be partly based on subjective criteria (physician opinions and preferences). In fact, the selection criteria can be clarified as: treatment decisions rely not only on seizure type, efficacy and tolerability profiles but also on patient-related factors.

Experimental determination and allometric prediction of vitreous volume, and retina and lens weights in Göttingen minipigs.

2008-01-01

To determine the vitreous volume, and retinal and lens wet weights in male and female Göttingen minipigs of different age groups. Vitreous, lens and retina were isolated from fresh minipig eyes. Vitreous volume, lens and retina weight were measured and allometric scaling was utilized to predict these parameters. There were no gender differences in body weights or retina and lens weights in the three age groups examined in this study. For vitreous volumes, females had a significantly larger volume (approximately 10%-12%) than males in the 4-6 and 6-8 month, but not in the 8-11-month group. The mean body weight increased from 12.2 +/- 2.6 kg (4-6 months) to 19.4 +/- 4.0 kg (8-11 months). In the same period, the mean vitreous volume increased from 2.00 +/- 0.28 to 2.67 +/- 0.31 mL, while the mean retinal and lens weights increased from 114 +/- 22 to 126 +/- 17 mg, and from 298 +/- 26 to 392 +/- 15 mg, respectively. Allometric analysis between six species for vitreous volume and four species for lens weight covering a weight range of 260-fold was not able to estimate the vitreous volume, but it did predict the lens weight in 8-11 months minipigs. Overall these measurements add important context to intraocular pharmacology studies, and will help in the improved design and interpretation of such experiments.

[Toric add-on intraocular lenses for correction of high astigmatism after pseudophakic keratoplasty].

PubMed

Hassenstein, A; Niemeck, F; Giannakakis, K; Klemm, M

2017-06-01

Perforating keratoplasty shows good morphological results with a clear cornea; however, a limiting factor is often the resulting astigmatism, which cannot be corrected with either glasses or contact lenses (CL) in up to 20% of the patients. We retrospectively investigated 15 patients after pseudophakic perforating keratoplasty, who received implantation of toric add-on intraocular lenses (IOL) to correct astigmatism. The mean preoperative astigmatism of 6.5 diopter (dpt) could be reduced to a mean postoperative value of 1.0 dpt. The mean visual acuity could be improved from a preoperative value of sc <0.05 (cc 0.6) to a postoperative value of sc 0.4 (cc 0.63). There were no complications except for one case of a lens extension tear. Based on our good experiences we now provide toric add-on IOL to all patients with pseudophakic perforating keratoplasty when this cannot be corrected or only insufficiently corrected by conservative methods.

In DA properties are weighted and outcomes are scored. The weighted scores for each candidate are totaled and final selection is based on the totals. Higher scores indicate better candidates. In PPA potential problems are assigned a seriousness factor and test outcomes are used to define the probability of occurrence. The seriousness-probability products are totaled and forms with minimal scores are preferred. DA and PPA have never been compared to the logical-elimination method. Additional data were available for two forms of McN-5707 to provide complete preformulation data for five candidate forms. Weight and seriousness factors (independent variables) were obtained from a survey of experienced formulators. Scores and probabilities (dependent variables) were provided independently by Preformulation. The rankings of the five candidate forms, best to worst, were similar for all three methods. These results validate the applicability of DA and PPA for candidate form selection. DA and PPA are particularly applicable in cases where there are many candidate forms and where each form has some degree of unfavorable properties.

Electric motor/controller design tradeoffs for noise, weight, and efficiency

DOE Office of Scientific and Technical Information (OSTI.GOV)

Kopp, N.L.; Brown, G.W.

1994-12-31

It is common for an AUV [Autonomous Underwater Vehicle] designer to be put in the position of a subsystem hardware integrator. In the case of electric motors and controllers this may be more by necessity than choice because a suitable subsystems supplier cannot be found. As a result, motors and controllers are purchased from various manufacturers who may optimize the design of each part but hold system performance secondary in importance. Unlike hydraulics, an electric motor/controller system presents significant opportunities to improve noise, weight, and efficiency. But, these opportunities can best be recognized by a single source who not onlymore » understands the technology but has the ability to implement them in the development and manufacture of the product. An analysis is presented which explains the various design considerations of noise, weight and efficiency of electric motors and controllers for submersible AUV`s. In concert with the design considerations, their interrelationships are discussed as to how they affect each other in the overall optimization of the system. In conclusion, a matrix is created which shows how the resultant system parameters of noise, weight, and efficiency may be ``traded off`` to tailor the best overall system for the application. 1 ref.« less

Treatment of Obesity: Weight Loss and Bariatric Surgery

Wolfe, Bruce M.; Kvach, Elizaveta; Eckel, Robert H.

2016-01-01

This review focuses on the mechanisms underlying, and indications for, bariatric surgery in the reduction of cardiovascular disease (CVD) as well as other expected benefits of this intervention. The fundamental basis for bariatric surgery for the purpose of accomplishing weight loss is the determination that severe obesity is a disease associated with multiple adverse effects on health which can be reversed or improved by successful weight loss in patients who have been unable to sustain weight loss by non-surgical means. An explanation of possible indications for weight loss surgery as well as specific bariatric surgical procedures is presented, along with review of the safety literature of such procedures. Procedures that are less invasive or those that involve less gastrointestinal rearrangement accomplish considerably less weight loss but have substantially lower perioperative and longer-term risk. The ultimate benefit of weight reduction relates to the reduction of the co-morbidities, quality of life and all-cause mortality. With weight loss being the underlying justification for bariatric surgery in ameliorating CVD risk, current evidence-based research is discussed concerning body fat distribution, dyslipidemia, hypertension, diabetes, inflammation, obstructive sleep apnea and others. The rationale for bariatric surgery reducing CVD events is discussed and juxtaposed with impacts on all-cause mortalities. Given the improvement of established obesity-related CVD risk factors following weight loss, it is reasonable to expect a reduction of CVD events and related mortality following weight loss in populations with obesity. The quality of the current evidence is reviewed and future research opportunities and summaries are stated. PMID:27230645

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

A growing number of studies have shown consistent evidence of the harmful effects of air pollution on human health, as well as its effects on newborn weight. The objective of this study is to evaluate the effect of air pollution on birth weight, more specifically the insufficient birth weight (identified between 2,500 and 2,999 grams). This was a cross-sectional study based on data gathered from all babies born to mothers living in São José dos Campos, São Paulo, Brazil, between the years of 2006 to 2010. The association between maternal exposure to air pollution and birth weight was examined using logistic regression (both univariate and multivariate) to consider the average concentration of each pollutant during the 1st and 3rd trimesters and the months of the 1st trimester. Of the 39,453 total live births during the study period, 10,542 (26.7%) newborns had insufficient weight. In multiple logistic analysis, maternal exposure to particulate matter in the 1st and 3rd trimester of pregnancy had a greater chance for insufficient weight. There is a chance of 1.07 (95%CI 1.00 - 1.14) for an insufficient weight scenario for exposure (to the 2nd quartile) of particulate matter in the 1st trimester and 1.10 (95%CI 1.04 - 1.18) for exposure (the 3rd quartile) in the 3rd trimester. The survey results indicate that maternal exposure to air pollution in the 1st and 3rd trimesters of pregnancy for residents of São José dos Campos create considerable potential to cause insufficient weight.

Literature-based concept profiles for gene annotation: the issue of weighting.

Text-mining has been used to link biomedical concepts, such as genes or biological processes, to each other for annotation purposes or the generation of new hypotheses. To relate two concepts to each other several authors have used the vector space model, as vectors can be compared efficiently and transparently. Using this model, a concept is characterized by a list of associated concepts, together with weights that indicate the strength of the association. The associated concepts in the vectors and their weights are derived from a set of documents linked to the concept of interest. An important issue with this approach is the determination of the weights of the associated concepts. Various schemes have been proposed to determine these weights, but no comparative studies of the different approaches are available. Here we compare several weighting approaches in a large scale classification experiment. Three different techniques were evaluated: (1) weighting based on averaging, an empirical approach; (2) the log likelihood ratio, a test-based measure; (3) the uncertainty coefficient, an information-theory based measure. The weighting schemes were applied in a system that annotates genes with Gene Ontology codes. As the gold standard for our study we used the annotations provided by the Gene Ontology Annotation project. Classification performance was evaluated by means of the receiver operating characteristics (ROC) curve using the area under the curve (AUC) as the measure of performance. All methods performed well with median AUC scores greater than 0.84, and scored considerably higher than a binary approach without any weighting. Especially for the more specific Gene Ontology codes excellent performance was observed. The differences between the methods were small when considering the whole experiment. However, the number of documents that were linked to a concept proved to be an important variable. When larger amounts of texts were available for the generation of

A novel weight determination method for time series data aggregation

NASA Astrophysics Data System (ADS)

Xu, Paiheng; Zhang, Rong; Deng, Yong

2017-09-01

Aggregation in time series is of great importance in time series smoothing, predicting and other time series analysis process, which makes it crucial to address the weights in times series correctly and reasonably. In this paper, a novel method to obtain the weights in time series is proposed, in which we adopt induced ordered weighted aggregation (IOWA) operator and visibility graph averaging (VGA) operator and linearly combine the weights separately generated by the two operator. The IOWA operator is introduced to the weight determination of time series, through which the time decay factor is taken into consideration. The VGA operator is able to generate weights with respect to the degree distribution in the visibility graph constructed from the corresponding time series, which reflects the relative importance of vertices in time series. The proposed method is applied to two practical datasets to illustrate its merits. The aggregation of Construction Cost Index (CCI) demonstrates the ability of proposed method to smooth time series, while the aggregation of The Taiwan Stock Exchange Capitalization Weighted Stock Index (TAIEX) illustrate how proposed method maintain the variation tendency of original data.

Coupling analysis of high Q resonators in add-drop configuration through cavity ringdown spectroscopy

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.

Hamlyn, Nicolle; Behm, David G; Young, Warren B

2007-11-01

The purpose of this study was to examine the extent of activation in various trunk muscles during dynamic weight-training and isometric instability exercises. Sixteen subjects performed squats and deadlifts with 80% 1 repetition maximum (1RM), as well as with body weight as resistance and 2 unstable calisthenic-type exercises (superman and sidebridge). Electromyographic (EMG) activity was measured from the lower abdominals (LA), external obliques (EO), upper lumbar erector spinae (ULES), and lumbar-sacral erector spinae (LSES) muscle groups. Results indicated that the LSES EMG activity during the 80% 1RM squat significantly exceeded 80% 1RM deadlift LSES EMG activity by 34.5%. The LSES EMG activity of the 80% 1RM squat also exceeded the body weight squat, deadlift, superman, and sidebridge by 56, 56.6, 65.5, and 53.1%, respectively. The 80% 1RM deadlift ULES EMG activity significantly exceeded the 80% 1RM squat exercise by 12.9%. In addition, the 80% 1RM deadlift ULES EMG activity also exceeded the body weight squat, deadlift, superman, and sidebridge exercises by 66.7, 65.5, 69.3, and 68.6%, respectively. There were no significant changes in EO or LA activity. Therefore, the augmented activity of the LSES and ULES during 80% 1RM squat and deadlift resistance exercises exceeded the activation levels achieved with the same exercises performed with body weight and selected instability exercises. Individuals performing upright, resisted, dynamic exercises can achieve high trunk muscle activation and thus may not need to add instability device exercises to augment core stability training.

Weight-ing: the experience of waiting on weight loss.

Glenn, Nicole M

Perhaps we want to be perfect, strive for health, beauty, and the admiring gaze of others. Maybe we desire the body of our youth, the "healthy" body, the body that has just the right fit. Regardless of the motivation, we might find ourselves striving, wanting, and waiting on weight loss. What is it to wait on weight loss? I explore the meaning of this experience-as-lived using van Manen's guide to phenomenological reflection and writing. Weight has become an increasing focus of contemporary culture, demonstrated, for example, by a growing weight-loss industry and global obesity "epidemic." Weight has become synonymous with health status, and weight loss with "healthier." I examine the weight wait through experiences of the common and uncommon, considering relations to time, body, space, and the other with the aim of evoking a felt, embodied, emotive understanding of the meaning of waiting on weight loss. I also discuss the implications of the findings.

A force plate measurement system to assess hindlimb weight support of spinal cord injured rats.

This paper describes a force plate system for quantitative measurement of the hindlimb weight support of rats. The system is built around a microcontroller and uses strain gauges to measure individually the weight applied by each limb and also the general hindquarters of the rat. The sum of weights on the individual force plates adds up to the total weight of the rat. Mathematical comparison of the weights of the different force plates allows calculation of the weight percentage of the hindquarters (W%HQ=(hindquarters weight/total weight)x100%). When hindlimb impairment is high, the W%HQ is high and vise versa, allowing hindlimb weight support to be evaluated by the W%HQ. An actual laboratory embodiment is demonstrated and real experiments are performed on spinal cord damaged rats. W%HQ results are compared with Basso, Beattie, Bresnahan (BBB) locomotor behavioural test results on the same rats at approximately the same time. When a rat is placed in the correct position of the test chamber, the user can use a local keypad/LCD display (standalone mode) or the PC keyboard/display to control the system and access the current data. Comparing our results with those of the BBB method confirms the proposed hardware and W%HQ metric represent very well the recovery of a rat after spinal cord injury. Medical investigators report that under actual use, the presented system is stable, accurate and easy to use. Additional advantages of the presented force plate system include stand-alone capability, non-dependence on subjective human judgement and quantitative results. (c) 2010 Elsevier B.V.

Contact Nd:YAG tonsillectomy using synthetic sapphire blades appears to meet or exceed standards established by spot monopolar cautery. Subjects' percentage of weight loss and return to work/social activities was measured and the laser group displayed less percentage of weight loss, faster return to pre-operative weight, and less recovery time than the comparative cautery group. Because of the unique nature of Nd:YAG laser light combined with sapphire blades, special consideration should be given to these accessories by physicians before attempting tissue cutting and vessel coagulation. The author believes that the extent of physician training and proficiency may be key to the success of soft tissue head and neck applications, such as tonsillectomy, which will have an effect on the outcome of clinical data.

Weight and power savings shaft encoder interfacing techniques for aerospace applications

1986-01-01

Many aerospace applications for shaft angle digitizers such as optical shaft encoders require special features that are not usually required on commercial products. Among the most important user considerations are the lowest possible weight and power consumption. A variety of mechanical and electrical interface techniques that have large potential weight and power savings are described. The principles to be presented apply to a wide variety of encoders, ranging from 16 to 22 bit resolution and with diameters from 152 to 380 mm (6 to 15 in.).

Hypervelocity Impact Experiments on Epoxy/Ultra-High Molecular Weight Polyethylene Composite Panels Reinforced with Nanotubes

Advanced composites with multi-functional capabilities are of great interest to the designers of aerospace structures. Polymer matrix composites (PMCs) reinforced with high strength fibers provide a lightweight and high strength alternative to metals and metal alloys conventionally used in aerospace architectures. Novel reinforcements such as nanofillers offer potential to improve the mechanical properties and add multi-functionality such as radiation resistance and sensing capabilities to the PMCs. This paper reports the hypervelocity impact (HVI) test results on ultra-high molecular weight polyethylene (UHMWPE) fiber composites reinforced with single-walled carbon nanotubes (SWCNT) and boron nitride nanotubes (BNNT). Woven UHMWPE fabrics, in addition to providing excellent impact properties and high strength, also offer radiation resistance due to inherent high hydrogen content. SWCNT have exceptional mechanical and electrical properties. BNNT (figure 1) have high neutron cross section and good mechanical properties that add multi-functionality to this system. In this project, epoxy based UHMWPE composites containing SWCNT and BNNT are assessed for their use as bumper shields and as intermediate plates in a Whipple Shield for HVI resistance. Three composite systems are prepared to compare against one another: (I) Epoxy/UHMWPE, (II) Epoxy/UHMWPE/SWCNT and (III) Epoxy/UHMWPE/SWCNT/BNNT. Each composite is a 10.0 by 10.0 by 0.11 cm3 panel, consisting of 4 layers of fabrics arranged in cross-ply orientation. Both SWCNT and BNNT are 0.5 weight % of the fabric preform. Hypervelocity impact tests are performed using a two-stage light gas gun at Rice University

Light weight dentures: An innovative technique.

Retention, stability and support are the basic principles on which the success of a complete denture relies. The severely resorbed maxillary and mandibular edentulous arches that are narrow and constricted with increased interarch space provide decreased support, retention and stability. To decrease the leverage, reduction in the weight of the prosthesis was recommended and also found beneficial. This article describes a simple procedure to reduce the weight of maxillary complete denture by use of an autopolymerizing acrylic resin shell which is incorporated during the packing stage. This method has the advantage of being easy and requires very little additional time. Hollow maxillary complete denture considerably reduces the weight of the prosthesis, which in turn prevents transmission of detrimental forces by reducing leverage action. This results in increased retention and stability and up to some extent it also preserves the existing residual alveolar ridge. The technique uses a clear matrix of trial denture to facilitate shaping of dough spacer to ensure an even thickness of acrylic to resist deformation and prevent seepage of saliva into the cavity making this technique more predictable. An autopolymerizing acrylic resin shell which creates hollow space and also has strength. Technique is simple to execute, easy economical and matching the shade of autopolymerizing acrylic resin with heat cures acrylic resin enhances esthetics. Light weight hollow dentures provide healthy and comfortable living for the geriatric edentulous patient.

Background: Intensive insulin treatment is bothersome in obese patients with type 2 diabetes mellitus. High insulin dosages further increase weight gain and the risk of hypoglycemia. Glucagon like peptide-1 receptor agonists decrease the insulin need, cause weight loss and reduce the risk of hypoglycemia. There is limited data about the effect of exenatide on obese diabetics under intensive insulin regimens. Methods: This retrospective case series report the clinical outcomes of 23 obese (13 morbidly obese) patients with uncontrolled type 2 diabetes mellitus (Age=59±10.44 years, body mass index 41.1±6.8 kg/m 2 , HbA1c 9.9±1.5%), under high dose (94.1±39.6 unit) intensive insulin. Exenatide twice daily was added for a mean follow-up period of 11.22±7.01 (3-30) months. Intensive insulin regimens were continued in 7 patients while the others were switched to basal insulin during the follow-up. Results: During the follow-up, mean HbA1c levels of the patients significantly improved (p=0.019), along with the significant decrease in body mass index and the total insulin need (p<0.001 for both). Baseline insulin dosages were significantly higher in the intensive regimen group (p=0.013) while other demographical and clinical characteristics were similar. No significant difference was present between the groups regarding the alterations of HbA1c, body mass index and the reduction in total insulin dosages. Conclusion: Add on exenatide appears to be a rational treatment modality in uncontrolled obese patients with type 2 diabetes mellitus despite intensive insulin regimens. Further prospective randomized studies with longer follow-up periods are recommended. © Georg Thieme Verlag KG Stuttgart · New York.

Rapid paediatric weight estimation methods in the emergency setting have not been evaluated for South East Asian children. This study aims to assess the accuracy and precision of three such methods in Singapore children: Broselow-Luten (BL) tape, Advanced Paediatric Life Support (APLS) (estimated weight (kg) = 2 (age + 4)) and Luscombe (estimated weight (kg) = 3 (age) + 7) formulae. We recruited 875 patients aged 1-10 years in a Paediatric Emergency Department in Singapore over a 2-month period. For each patient, true weight and height were determined. True height was cross-referenced to the BL tape markings and used to derive estimated weight (virtual BL tape method), while patient's round-down age (in years) was used to derive estimated weights using APLS and Luscombe formulae, respectively. The percentage difference between the true and estimated weights was calculated. For each method, the bias and extent of agreement were quantified using Bland-Altman method (mean percentage difference (MPD) and 95% limits of agreement (LOA)). The proportion of weight estimates within 10% of true weight (p₁₀) was determined. The BL tape method marginally underestimated weights (MPD +0.6%; 95% LOA -26.8% to +28.1%; p₁₀ 58.9%). The APLS formula underestimated weights (MPD +7.6%; 95% LOA -26.5% to +41.7%; p₁₀ 45.7%). The Luscombe formula overestimated weights (MPD -7.4%; 95% LOA -51.0% to +36.2%; p₁₀ 37.7%). Of the three methods we evaluated, the BL tape method provided the most accurate and precise weight estimation for Singapore children. The APLS and Luscombe formulae underestimated and overestimated the children's weights, respectively, and were considerably less precise. © 2013 The Authors.

Height and weight information is commonly used in clinical trials and in making therapeutic decisions in medical practice. In both settings, the data are often obtained by self-report. If erroneous, this practice could lead to inaccuracies in estimating renal function and medication doses or to inaccurate outcomes of research studies. Previous publications have reported lack of reliability of self-reported weight and height in the general population but have not addressed age-specific and ethnicity-specific subgroups in the U.S. population. The inaccuracy of self-reported weight and height could be particularly significant in times of considerable changes in body weight, such as at menopause, which is often associated with weight gain. We assessed the validity of self-reported height and weight in 428 women within the first 5 years of menopause, 70.6% of whom were Hispanic. Participants overestimated their height by 2.2±3.5 cm (mean±standard deviation [SD]) and underestimated their weight by 1.5±2.9 kg. As a group, based on self-reported measures, 33.3% were misclassified with respect to body mass index (BMI) category, and the difference between measured BMI and self-reported BMI was similar between Hispanic white and non-Hispanic white women, positively related to measured weight, and inversely related to measured height, years from menopause, and multiple parity. From the public health perspective, inaccurate self-report could lead to a considerable underestimation of the current obesity prevalence rates. In our study population, the prevalence of obesity (BMI ≥30 kg/m(2)) was 6.3% based on self-reported values and 18% based on measured height and weight, representing a 3-fold underestimation.

2015-01-01

Objective To assess factors determining the reaction of individuals to the threats of overweight and obesity and to examine the interdependencies between weight-reducing strategies. Methods Cross-country survey covering 19 countries and 13,155 interviews. Data were analysed using a bivariate probit model that allows simultaneously analysing two weight-reducing strategies. Results Results show that weight-reducing strategies chosen are not independent from each other. Findings also reveal that different strategies are chosen by different population segments. Women are more likely to change their dietary patterns and less likely to become physically active after surpassing a weight threshold. In addition, the probability of a dietary change in case of overweight differs considerably between countries. The study also reveals that attitudes are an important factor for the strategy choice. Conclusions It is vital for public health policies to understand determinants of citizens’ engagement in weight reduction strategies once a certain threshold is reached. Thus, results can support the design of public health campaigns and programmes that aim to change community or national health behaviour trends taking into account, e.g., national differences.

Schizophrenia is a psychiatric disorder with a higher mortality than that of the general population. Most of the deaths are due to cardiovascular causes and are related to metabolic risks. This risk is due not only to antipsychotics but also to inherent factors of the disorder. Studies in the West have shown topiramate to be effective in schizophrenia to reduce weight gain and for symptomatic control. Whether this is effective for South Asians is not known. It is important because South Asians have a higher risk of metabolic syndrome. We aim to conduct a double-blind, randomized controlled trial comparing topiramate add-on therapy with treatment as usual with antipsychotics in patients with schizophrenia in an outpatient setting in Sri Lanka. Ninety patients with schizophrenia presenting to the Colombo North Teaching Hospital will be randomized to intervention and control groups equally using permuted block randomization. Patients with comorbid metabolic disorders and taking prescribed weight-controlling medications will be excluded. The intervention group will be prescribed topiramate in addition to their antipsychotics in a predefined dosing regimen targeting a dose of 100 mg per day. The control subjects are to receive a placebo. As the primary outcome, anthropometric measurements including weight, waist circumference, skinfold thickness, and body mass index will be recorded at baseline and monthly during the study period of 3 months. The secondary outcome is the change in symptoms according to the clinician-administered Brief Psychiatric Rating Scale. Assessment of capacity will be performed and informed consent obtained from all subjects. Ethics approval has been obtained from the ethical review committee of the Faculty of Medicine, University of Kelaniya, and the trial has been registered in the Sri Lanka Clinical Trials Registry. In this double-blind, randomized controlled trial, we will attempt to assess the effectiveness of topiramate as an add

Post-partum weight retention (PWR) has been identified as a critical pathway for long-term overweight and obesity. In recent years, psychological factors have been demonstrated to play a key role in contributing to and maintaining PWR. Therefore, the aim of this study was to explore the relationship between post-partum psychological distress and PWR at 9 months, after controlling for maternal weight factors, sleep quality, sociocontextual influences, and maternal behaviours. Pregnant women (N = 126) completed a series of questionnaires at multiple time points from early pregnancy until 9 months post-partum. Hierarchical regression indicated that gestational weight gain, shorter duration (6 months or less) of breastfeeding, and post-partum body dissatisfaction at 3 and 6 months are associated with higher PWR at 9 months; stress, depression, and anxiety had minimal influence. Interventions aimed at preventing excessive PWR should specifically target the prevention of body dissatisfaction and excessive weight gain during pregnancy. What is already known on this subject? Post-partum weight retention (PWR) is a critical pathway for long-term overweight and obesity. Causes of PWR are complex and multifactorial. There is increasing evidence that psychological factors play a key role in predicting high PWR. What does this study add? Post-partum body dissatisfaction at 3 and 6 months is associated with PWR at 9 months post-birth. Post-partum depression, stress and anxiety have less influence on PWR at 9 months. Interventions aimed at preventing excessive PWR should target body dissatisfaction. © 2013 The British Psychological Society.

We demonstrate an add-drop filter based on a dual photonic crystal nanobeam cavity system that emulates the operation of a traveling wave resonator, and, thus, provides separation of the through and drop port transmission from the input port. The device is on a 3×3  mm chip fabricated in an advanced microelectronics silicon-on-insulator complementary metal-oxide semiconductor (SOI CMOS) process (IBM 45 nm SOI) without any foundry process modifications. The filter shows 1 dB of insertion loss in the drop port with a 3 dB bandwidth of 64 GHz, and 16 dB extinction in the through port. To the best of our knowledge, this is the first implementation of a port-separating, add-drop filter based on standing wave cavities coupled to conventional waveguides, and demonstrates a performance that suggests potential for photonic crystal devices within optical immersion lithography-based advanced CMOS electronics-photonics integration.

Perceived weight discrimination and changes in weight, waist circumference, and weight status.

To examine associations between perceived weight discrimination and changes in weight, waist circumference, and weight status. Data were from 2944 men and women aged ≥50 years participating in the English Longitudinal Study of Ageing. Experiences of weight discrimination were reported in 2010-2011 and weight and waist circumference were objectively measured in 2008-2009 and 2012-2013. ANCOVAs were used to test associations between perceived weight discrimination and changes in weight and waist circumference. Logistic regression was used to test associations with changes in weight status. All analyses adjusted for baseline BMI, age, sex, and wealth. Perceived weight discrimination was associated with relative increases in weight (+1.66 kg, P < 0.001) and waist circumference (+1.12 cm, P = 0.046). There was also a significant association with odds of becoming obese over the follow-up period (OR = 6.67, 95% CI 1.85-24.04) but odds of remaining obese did not differ according to experiences of weight discrimination (OR = 1.09, 95% CI 0.46-2.59). Our results indicate that rather than encouraging people to lose weight, weight discrimination promotes weight gain and the onset of obesity. Implementing effective interventions to combat weight stigma and discrimination at the population level could reduce the burden of obesity. © 2014 The Authors Obesity published by Wiley Periodicals, Inc. on behalf of The Obesity Society (TOS).

Weight, gravitation, inertia, and tides

Pujol, Olivier; Lagoute, Christophe; Pérez, José-Philippe

2015-11-01

This paper deals with the factors that influence the weight of an object near the Earth's surface. They are: (1) the Earth's gravitational force, (2) the centrifugal force due to the Earth's diurnal rotation, and (3) tidal forces due to the gravitational field of the Moon and Sun, and other solar system bodies to a lesser extent. Each of these three contributions is discussed and expressions are derived. The relationship between weight and gravitation is thus established in a direct and pedagogical manner readily understandable by undergraduate students. The analysis applies to the Newtonian limit of gravitation. The derivation is based on an experimental (or operational) definition of weight, and it is shown that it coincides with the Earth’s gravitational force modified by diurnal rotation around a polar axis and non-uniformity of external gravitational bodies (tidal term). Two examples illustrate and quantify these modifications, respectively the Eötvös effect and the oceanic tides; tidal forces due to differential gravitation on a spacecraft and an asteroid are also proposed as examples. Considerations about inertia are also given and some comments are made about a widespread, yet confusing, explanation of tides based on a centrifugal force. Finally, the expression of the potential energy of the tide-generating force is established rigorously in the appendix.

Weight Changes in General Practice.

PubMed

Køster-Rasmussen, Rasmus

2017-06-01

weight loss and mortality in patients with type 2 diabetes are in opposition to the prevailing observational literature. Harrington's meta-analysis of intentional weight loss and the underlying studies are evaluated along with the Look AHEAD trial and a number of diabetes prevention studies. Difficulties in conducting and interpreting weight change studies are discussed.   CONCLUSIONS: Surprisingly, intentional therapeutic weight loss in patients with type 2 diabetes, supervised by a medical doctor, did not seem to reduce the long-term risk for CVD, CVD-mortality or all-cause mortality. The contradictions between our results and the prevailing observational evidence may be explained by methodological weaknesses favoring weight loss in earlier studies. Consequently, there is no good evidence to support that intentional weight loss will reduce the risk of CVD or mortality in any group of patients in general practice or in the general population. Age was a powerful determinant of weight changes and the 'normal weight development' can be taken into consideration when evaluating weight studies, and when general practitioners are following their patients over time. Compared with age, sex, education, and comorbidity, lifestyle factors like the dietary intake and physical activity seemed to be of less importance for long-term weight development. An exception to this was smoking or smoking cessation. Based on the scientific literature in the field and on the results of article 3, it seems uncertain whether weight loss is beneficial or harmful in terms of mortality and cardiovascular morbidity in patients with diabetes and in overweight people in general. Improvements in for instance psychosocial factors and diabetes prevention may well be short term as only few are able to a maintain weight loss. Rather than going for weight loss in overweight high risk patients, it seems more rational for general practitioners to focus on other lifestyle changes like for instance Mediterranean

Adopting epidemic model to optimize medication and surgical intervention of excess weight

NASA Astrophysics Data System (ADS)

Sun, Ruoyan

2017-01-01

We combined an epidemic model with an objective function to minimize the weighted sum of people with excess weight and the cost of a medication and surgical intervention in the population. The epidemic model is consisted of ordinary differential equations to describe three subpopulation groups based on weight. We introduced an intervention using medication and surgery to deal with excess weight. An objective function is constructed taking into consideration the cost of the intervention as well as the weight distribution of the population. Using empirical data, we show that fixed participation rate reduces the size of obese population but increases the size for overweight. An optimal participation rate exists and decreases with respect to time. Both theoretical analysis and empirical example confirm the existence of an optimal participation rate, u*. Under u*, the weighted sum of overweight (S) and obese (O) population as well as the cost of the program is minimized. This article highlights the existence of an optimal participation rate that minimizes the number of people with excess weight and the cost of the intervention. The time-varying optimal participation rate could contribute to designing future public health interventions of excess weight.

The Association Between Maternal Early Life Forced Sexual Intercourse and Offspring Birth Weight: The Role of Socioeconomic Status.

Gavin, Amelia R; Morris, Julia

2017-05-01

This study utilizes a life-course framework to investigate whether maternal early life forced sexual intercourse operates in conjunction with health behaviors during adolescence, young adulthood, and the prenatal period to influence offspring birth weight. Using data from the 1994-2009 National Longitudinal Study of Adolescent Health (Add Health), we examined whether early life forced sexual intercourse predicted offspring birth weight through a mediated pathway, including depressive symptoms, substance use, and prenatal cigarette smoking. We stratify our analysis by socioeconomic status (SES) to determine whether the proposed pathways operate similarly, or differently, according to SES. Our findings suggest that the pathways through which forced sexual intercourse affects offspring birth weight differ by SES. Among middle-to-high SES women, we found a mediated pathway linking forced sexual intercourse to offspring birth weight with prenatal cigarette smoking predicting lower offspring birth weight. Among low SES women, however, we did not find a mediated pathway linking forced sexual intercourse to birth weight. Findings suggest that prenatal cigarette smoking was not a mechanism of influence in the pathway between maternal early life forced sexual intercourse and offspring birth weight for low SES women. Our findings suggest that forced sexual intercourse may influence infant birth weight in the next generation. Infants born with a low birth weight are at increased risk for a myriad of adverse outcomes across the life-course. Study results suggest the importance of interventions designed to reduce behavioral risks and to support health promoting behaviors among survivors in the short term, in an effort to prevent long-term consequences among later-born offspring.

Understanding the metabolic and health effects of low-calorie sweeteners: methodological considerations and implications for future research

2016-01-01

Consumption of foods, beverages, and packets containing low-calorie sweeteners (LCS) has increased markedly across gender, age, race/ethnicity, weight status, and socioeconomic subgroups. However, well-controlled intervention studies rigorously evaluating the health effects of LCS in humans are limited. One of the key questions is whether LCS are indeed a beneficial strategy for weight management and prevention of obesity. The current review discusses several methodological considerations in the design and interpretation of these studies. Specifically, we focus on the selection of study participants, inclusion of an appropriate control, importance of considering habitual LCS exposure, selection of specific LCS, dose and route of LCS administration, choice of study outcomes, and the context and generalizability of the study findings. These critical considerations will guide the design of future studies and thus assist in understanding the health effects of LCS. PMID:26936185

Adolescents view thousands of food commercials annually, but little is known about how individual differences in neural response to food commercials relate to weight gain. To add to our understanding of individual risk factors for unhealthy weight gain and environmental contributions to the obesity epidemic, we tested the associations between reward region (striatum and orbitofrontal cortex [OFC]) responsivity to food commercials and future change in body mass index (BMI). Adolescents (N = 30) underwent a scan session at baseline while watching a television show edited to include 20 food commercials and 20 nonfood commercials. BMI was measured at baseline and 1-year follow-up. Activation in the striatum, but not OFC, in response to food commercials relative to nonfood commercials and in response to food commercials relative to the television show was positively associated with change in BMI over 1-year follow-up. Baseline BMI did not moderate these effects. The results suggest that there are individual differences in neural susceptibility to food advertising. These findings highlight a potential mechanism for the impact of food marketing on adolescent obesity. © 2014 The Obesity Society.

Birth weight and infant growth: optimal infant weight gain versus optimal infant weight.

2007-01-01

Infant growth assessment often focuses on "optimal" infant weights and lengths at specific ages, while de-emphasizing infant weight gain. Objective of this study was to examine infant growth patterns by measuring infant weight gain relative to birth weight. We conducted this study based on data collected in a prospective cohort study including 3,302 births with follow up examinations of infants between the ages of 8 and 18 months. All infants were participants in the Louisiana State Women, Infant and Children Supplemental Food Program between 1999 and 2001. Growth was assessed by infant weight gain percentage (IWG%, defined as infant weight gain divided by birth weight) as well as by mean z-scores and percentiles for weight-for-age, length-for-age, and weight-for-length calculated based on growth charts published by the U.S. Centers for Disease Control (CDC). An inverse relationship was noted between birth weight category and IWG% (from 613.9% for infants with birth weights <1500 g to 151.3% for infants with birth weights of 4000 g or more). In contrast, low birth weight infants had lower weight-for-age, weight-for-length z-scores and percentiles compared to normal birth weight infants according to CDC growth charts. Although low birth weight infants had lower anthropometric measures compared to a national reference population, they had significant catch-up growth; High birth weight infants had significant slow-down growth. We suggest that growth assessments should compare infants' anthropometric data to their own previous growth measures as well as to a reference population. Further studies are needed to identify optimal ranges of infant weight gain.

A low-complexity add-on score for protein remote homology search with COMER.

PubMed

Margelevicius, Mindaugas

2018-06-15

Protein sequence alignment forms the basis for comparative modeling, the most reliable approach to protein structure prediction, among many other applications. Alignment between sequence families, or profile-profile alignment, represents one of the most, if not the most, sensitive means for homology detection but still necessitates improvement. We aim at improving the quality of profile-profile alignments and the sensitivity induced by them by refining profile-profile substitution scores. We have developed a new score that represents an additional component of profile-profile substitution scores. A comprehensive evaluation shows that the new add-on score statistically significantly improves both the sensitivity and the alignment quality of the COMER method. We discuss why the score leads to the improvement and its almost optimal computational complexity that makes it easily implementable in any profile-profile alignment method. An implementation of the add-on score in the open-source COMER software and data are available at https://sourceforge.net/projects/comer. The COMER software is also available on Github at https://github.com/minmarg/comer and as a Docker image (minmar/comer). Supplementary data are available at Bioinformatics online.

WAIS-IV subtest covariance structure: conceptual and statistical considerations.

Ward, L Charles; Bergman, Maria A; Hebert, Katina R

2012-06-01

D. Wechsler (2008b) reported confirmatory factor analyses (CFAs) with standardization data (ages 16-69 years) for 10 core and 5 supplemental subtests from the Wechsler Adult Intelligence Scale-Fourth Edition (WAIS-IV). Analyses of the 15 subtests supported 4 hypothesized oblique factors (Verbal Comprehension, Working Memory, Perceptual Reasoning, and Processing Speed) but also revealed unexplained covariance between Block Design and Visual Puzzles (Perceptual Reasoning subtests). That covariance was not included in the final models. Instead, a path was added from Working Memory to Figure Weights (Perceptual Reasoning subtest) to improve fit and achieve a desired factor pattern. The present research with the same data (N = 1,800) showed that the path from Working Memory to Figure Weights increases the association between Working Memory and Matrix Reasoning. Specifying both paths improves model fit and largely eliminates unexplained covariance between Block Design and Visual Puzzles but with the undesirable consequence that Figure Weights and Matrix Reasoning are equally determined by Perceptual Reasoning and Working Memory. An alternative 4-factor model was proposed that explained theory-implied covariance between Block Design and Visual Puzzles and between Arithmetic and Figure Weights while maintaining compatibility with WAIS-IV Index structure. The proposed model compared favorably with a 5-factor model based on Cattell-Horn-Carroll theory. The present findings emphasize that covariance model comparisons should involve considerations of conceptual coherence and theoretical adherence in addition to statistical fit.

Fasting for weight loss: an effective strategy or latest dieting trend?

PubMed

Johnstone, A

2015-05-01

With the increasing obesity epidemic comes the search for effective dietary approaches for calorie restriction and weight loss. Here I examine whether fasting is the latest 'fad diet' as portrayed in popular media and discuss whether it is a safe and effective approach or whether it is an idiosyncratic diet trend that promotes short-term weight loss, with no concern for long-term weight maintenance. Fasting has long been used under historical and experimental conditions and has recently been popularised by 'intermittent fasting' or 'modified fasting' regimes, in which a very low-calorie allowance is allowed, on alternate days (ADF) or 2 days a week (5:2 diet), where 'normal' eating is resumed on non-diet days. It is a simple concept, which makes it easy to follow with no difficult calorie counting every other day. This approach does seem to promote weight loss, but is linked to hunger, which can be a limiting factor for maintaining food restriction. The potential health benefits of fasting can be related to both the acute food restriction and chronic influence of weight loss; the long-term effect of chronic food restriction in humans is not yet clear, but may be a potentially interesting future dietary strategy for longevity, particularly given the overweight epidemic. One approach does not fit all in the quest to achieve body weight control, but this could be a dietary strategy for consideration. With the obesity epidemic comes the search for dietary strategies to (i) prevent weight gain, (ii) promote weight loss and (iii) prevent weight regain. With over half of the population of the United Kingdom and other developed countries being collectively overweight or obese, there is considerable pressure to achieve these goals, from both a public health and a clinical perspective. Certainly not one dietary approach will solve these complex problems. Although there is some long-term success with gastric surgical options for morbid obesity, there is still a requirement

The relationship between sleep and weight in a sample of adolescents.

Lytle, Leslie A; Pasch, Keryn E; Farbakhsh, Kian

2011-02-01

Research to date in young children and adults shows a strong, inverse relationship between sleep duration and risk for overweight and obesity. Fewer studies examining this relationship have been conducted in adolescents. The purpose of the article is to describe the relationship between sleep and weight in a population of adolescents, controlling for demographics, energy intake, energy expenditure, and depression. This is a cross-sectional study of 723 adolescents participating in population-based studies of the etiologic factors related to obesity. We examined the relationship between three weight-related dependent variables obtained through a clinical assessment and three sleep variables obtained through self-report. Average caloric intake from dietary recalls, average activity counts based on accelerometers, and depression were included as covariates and the analysis was stratified by gender and grade level. Our results show that the relationship between sleep duration and BMI is evident in middle-school boys (β = -0.32, s.e. = 0.06: P < 0.001) and girls (β = -0.18, s.e. = 0.08: P = 0.02) but largely absent in high-school students. Differences in sleep patterns have little association with weight in males, but in high-school girls, waking up late on weekends as compared to weekdays is associated with lower body fat (β = -0.80, s.e. = 0.40: P = 0.05) and a healthy weight status (β = -0.28, s.e. = 0.14: P = 0.05). This study adds to the evidence that, particularly for middle-school boys and girls, inadequate sleep is a risk factor for early adolescent obesity. Future research needs to examine the relationship longitudinally and to study potential mediators of the relationship.

What can neuromorphic event-driven precise timing add to spike-based pattern recognition?

PubMed

2015-03-01

This letter introduces a study to precisely measure what an increase in spike timing precision can add to spike-driven pattern recognition algorithms. The concept of generating spikes from images by converting gray levels into spike timings is currently at the basis of almost every spike-based modeling of biological visual systems. The use of images naturally leads to generating incorrect artificial and redundant spike timings and, more important, also contradicts biological findings indicating that visual processing is massively parallel, asynchronous with high temporal resolution. A new concept for acquiring visual information through pixel-individual asynchronous level-crossing sampling has been proposed in a recent generation of asynchronous neuromorphic visual sensors. Unlike conventional cameras, these sensors acquire data not at fixed points in time for the entire array but at fixed amplitude changes of their input, resulting optimally sparse in space and time-pixel individually and precisely timed only if new, (previously unknown) information is available (event based). This letter uses the high temporal resolution spiking output of neuromorphic event-based visual sensors to show that lowering time precision degrades performance on several recognition tasks specifically when reaching the conventional range of machine vision acquisition frequencies (30-60 Hz). The use of information theory to characterize separability between classes for each temporal resolution shows that high temporal acquisition provides up to 70% more information that conventional spikes generated from frame-based acquisition as used in standard artificial vision, thus drastically increasing the separability between classes of objects. Experiments on real data show that the amount of information loss is correlated with temporal precision. Our information-theoretic study highlights the potentials of neuromorphic asynchronous visual sensors for both practical applications and theoretical

Weight distributions for turbo codes using random and nonrandom permutations

NASA Technical Reports Server (NTRS)

Dolinar, S.; Divsalar, D.

1995-01-01

This article takes a preliminary look at the weight distributions achievable for turbo codes using random, nonrandom, and semirandom permutations. Due to the recursiveness of the encoders, it is important to distinguish between self-terminating and non-self-terminating input sequences. The non-self-terminating sequences have little effect on decoder performance, because they accumulate high encoded weight until they are artificially terminated at the end of the block. From probabilistic arguments based on selecting the permutations randomly, it is concluded that the self-terminating weight-2 data sequences are the most important consideration in the design of constituent codes; higher-weight self-terminating sequences have successively decreasing importance. Also, increasing the number of codes and, correspondingly, the number of permutations makes it more and more likely that the bad input sequences will be broken up by one or more of the permuters. It is possible to design nonrandom permutations that ensure that the minimum distance due to weight-2 input sequences grows roughly as the square root of (2N), where N is the block length. However, these nonrandom permutations amplify the bad effects of higher-weight inputs, and as a result they are inferior in performance to randomly selected permutations. But there are 'semirandom' permutations that perform nearly as well as the designed nonrandom permutations with respect to weight-2 input sequences and are not as susceptible to being foiled by higher-weight inputs.

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.

There is mounting evidence that childhood leukaemia is associated with high birth weight, but few studies have examined the relationship between leukaemia and other perinatal factors that influence birth weight, such as maternal weight or gestational weight gain. This case-cohort study included 916 acute lymphocytic leukaemia (ALL) and 154 acute myeloid leukaemia (AML) cases diagnosed prior to age 10 years between 1985 and 2001 and born in New York State excluding New York City between 1978 and 2001. Controls (n=9686) were selected from the birth cohorts for the same years. Moderate increased risk of both ALL and AML was associated with birth weight 3500 g or more. For ALL, however, there was evidence of effect modification with birth weight and maternal prepregnancy weight. High birth weight was associated with ALL only when the mother was not overweight while heavier maternal weight was associated with ALL only when the infant was not high birth weight. Increased pregnancy-related weight gain was associated with ALL. For AML, birth weight under 3000 g and higher prepregnancy weight were both associated with increased risk. These findings suggest childhood leukaemia may be related to factors influencing abnormal fetal growth patterns. PMID:16736025

Background Differences in biological changes from weight loss by energy restriction and/or exercise may be associated with differences in long-term weight loss/regain. Objective To assess the effect of weight loss method on long-term changes in weight, body composition and chronic disease risk factors. Data Sources PubMed and Embase were searched (January 1990-October 2013) for studies with data on the effect of energy restriction, exercise (aerobic and resistance) on long-term weight loss. Twenty articles were included in this review. Study Eligibility Criteria Primary source, peer reviewed randomized trials published in English with an active weight loss period of >6 months, or active weight loss with a follow-up period of any duration, conducted in overweight or obese adults were included. Study Appraisal and Synthesis Methods Considerable heterogeneity across trials existed for important study parameters, therefore a meta-analysis was considered inappropriate. Results were synthesized and grouped by comparisons (e.g. diet vs. aerobic exercise, diet vs. diet + aerobic exercise etc.) and study design (long-term or weight loss/follow-up). Results Forty percent of trials reported significantly greater long-term weight loss with diet compared with aerobic exercise, while results for differences in weight regain were inconclusive. Diet+aerobic exercise resulted in significantly greater weight loss than diet alone in 50% of trials. However, weight regain (∼55% of loss) was similar in diet and diet+aerobic exercise groups. Fat-free mass tended to be preserved when interventions included exercise. PMID:25333384

Rotor dynamic considerations for large wind power generator systems

NASA Technical Reports Server (NTRS)

Ormiston, R. A.

1973-01-01

Successful large, reliable, low maintenance wind turbines must be designed with full consideration for minimizing dynamic response to aerodynamic, inertial, and gravitational forces. Much of existing helicopter rotor technology is applicable to this problem. Compared with helicopter rotors, large wind turbines are likely to be relatively less flexible with higher dimensionless natural frequencies. For very large wind turbines, low power output per unit weight and stresses due to gravitational forces are limiting factors. The need to reduce rotor complexity to a minimum favors the use of cantilevered (hingeless) rotor configurations where stresses are relieved by elastic deformations.

The effect of rider weight and additional weight in Icelandic horses in tölt: part I. Physiological responses.

This study examined the effect of increasing BW ratio (BWR) between rider and horse, in the BWR range common for Icelandic horses (20% to 35%), on heart rate (HR), plasma lactate concentration (Lac), BWR at Lac 4 mmol/l (W4), breathing frequency (BF), rectal temperature (RT) and hematocrit (Hct) in Icelandic horses. In total, eight experienced school-horses were used in an incremental exercise test performed outdoors on an oval riding track and one rider rode all horses. The exercise test consisted of five phases (each 642 m) in tölt, a four-beat symmetrical gait, at a speed of 5.4±0.1 m/s (mean±SD), where BWR between rider (including saddle) and horse started at 20% (BWR20), was increased to 25% (BWR25), 30% (BWR30), and 35% (BWR35) and finally decreased to 20% (BWR20b). Between phases, the horses were stopped (~5.5 min) to add lead weights to specially adjusted saddle bags and a vest on the rider. Heart rate was measured during warm-up, the exercise test and after 5, 15 and 30 min of recovery and blood samples were taken and BF recorded at rest, and at end of each of these aforementioned occasions. Rectal temperature was measured at rest, at end of the exercise test and after a 30-min recovery period. Body size and body condition score (BCS) were registered and a clinical examination performed on the day before the test and for 2 days after. Heart rate and BF increased linearly (P0.05), but negative correlations (P<0.05) existed between body size measurements and Hct. While HR, Hct and BF recovered to values at rest within 30 min, Lac and RT did not. All horses had no clinical remarks on palpation and at walk 1 and 2 days after the test. In conclusion, increasing BWR from 20% to 35% resulted in increased HR, Lac, RT and BF responses in the test group of experienced adult Icelandic riding horses. The horses mainly worked aerobically until BWR reached 22.7%, but considerable individual differences (17.0% to 27.5%) existed that were not linked to horse size, but

Despite being regularly bred in zoos, giraffes remain a challenge, especially in terms of feeding. Assessment of factors influencing growth and weight changes during ontogeny, as well as analysis of weight fluctuations in adult individuals, may become a critical point in captive diet evaluation. Knowledge about weight is a crucial husbandry tool; however, such data are rarely acquired. Using a unique dataset from regularly weighed Rothschild giraffes (Giraffa camelopardalis rothschildi) from Prague zoo, we determined the growth functions of male and female giraffes and calculated weight gains during giraffe ontogeny. The mean weights of adult males and females were 1307 ± 52 and 835 ± 45 kg, respectively confirming the large overall dimensions of G. c. rothschildi in comparison with other giraffe subspecies. As the giraffe is a polygynous species showing considerable sexual dimorphism, we expected male calves to have larger first weights and faster growth during the most intensive period of maternal care. Growth rates and daily weight gains were higher in males than in females during the whole postnatal period. Males grew faster and longer than females. However, differences in weight between males and females appeared as late as after 1 year of age. The weight of adult males and non-pregnant adult females fluctuated significantly across seasons, being the highest during the autumn and winter months, respectively which may reflect the different effects of sexual activity and feeding ratios in males and females.

[Weight maintenance after weight loss - how the body defends its weight].

PubMed

Holzapfel, C; Hauner, H

2011-01-01

Mean weight loss of most conservative therapeutic weight loss programmes is about five to six kilograms after one year. In our "obesogenic" environment it is difficult for persons to maintain the new weight. Also continuation of the programme cannot prevent a moderate weight increase in the follow-up year. The reasons for this are not clear: individual lifestyle, environmental and genetic factors may play a role, but also the complex regulatory system of the body "to defend its weight". Nevertheless, for weight maintenance a lifelong change of lifestyle is of critical importance. Concerning nutrition a fat-reduced diet with a decrease of energy density together with regular eating habits and adequate portion size promises the greatest benefit and is likely to allow sufficient satiety. © Georg Thieme Verlag KG Stuttgart · New York.

To evaluate the efficacy and safety of ipragliflozin versus placebo as add-on therapy to metformin and sitagliptin in Korean patients with type 2 diabetes mellitus (T2DM). This double-blind, placebo-controlled, multi-center, phase 3 study was conducted in Korea in 2015-2017. Patients were randomized to receive either ipragliflozin 50 mg/day or placebo once daily for 24 weeks in addition to metformin and sitagliptin. The primary endpoint was the change in glycated hemoglobin (HbA1c) from baseline to end of treatment (EOT). In total, 143 patients were randomized and 139 were included in efficacy analyses (ipragliflozin: 73, placebo: 66). Baseline mean (SD) HbA1c levels were 7.90% (0.69) for ipragliflozin add-on and 7.92% (0.79) for placebo. The corresponding mean (SD) changes from baseline to EOT were -0.79% (0.59) and 0.03% (0.84), respectively, in favor of ipragliflozin (adjusted mean difference: -0.83% [95% CI -1.07 to -0.59%]) (P<0.0001). More ipragliflozin-treated patients than placebo-treated patients achieved HbA1c target levels of <7.0% (44.4% vs. 12.1%) and <6.5% (12.5% vs. 1.5%) at EOT (P<0.05 for both). Fasting plasma glucose, fasting serum insulin, body weight, and homeostatic model assessment for insulin resistance decreased significantly at EOT, in favor of ipragliflozin (adjusted mean difference: -29.55 mg/dL, -1.50 μU/mL, -1.72 kg, and -0.99, respectively) (P<0.05 for all). Adverse event rates were similar between groups (ipragliflozin: 51.4%; placebo: 50.0%). No previously unreported safety concerns were noted. Ipragliflozin add-on to metformin and sitagliptin significantly improved glycemic parameters and demonstrated a good safety profile in Korean patients with inadequately controlled T2DM.

Zonisamide is licensed for adjunctive therapy for partial-onset seizures with or without secondary generalisation in patients 6 years and older and as monotherapy for the treatment of partial seizures in adult patients with newly diagnosed epilepsy, and shows a favourable pharmacokinetic profile with low interaction potential with other drugs. The aim of the present study was to gather real-life data on retention and modalities of zonisamide use when administered as only add-on treatment to a current AED monotherapy in adult patients with partial-onset seizures. This multicenter observational study was performed in 4 European countries and comprised three visits: baseline, and after 3 and 6 months. Data on patients' retention, reported efficacy, tolerability and safety, and quality of life was collected. Of 100 included patients, 93 could be evaluated. After 6 months, the retention rate of zonisamide add-on therapy was 82.8%. At this time, a reduction of seizure frequency of at least 50% was observed in 79.7% of patients, with 43.6% reporting seizure freedom over the last 3 months of the study period. Adverse events were reported by 19.4% of patients, with fatigue, agitation, dizziness, and headache being most frequent. Approximately 25% of patients were older than 60 years, many of whom suffered from late-onset epilepsy. Compared to younger patients, these patients showed considerable differences with regard to their antiepileptic drug regimen at baseline, and slightly higher responder and retention rates at 6 months. Despite limitations due to the non-interventional open-label design and the low sample size, the results show that zonisamide as only add-on therapy is well retained, indicating effectiveness in the majority of patients under real-life conditions.

To investigate whether saxagliptin add-on therapy to continuous subcutaneous insulin infusion (CSII) further improve blood glycemic control than CSII therapy in patients with newly diagnosed type 2 diabetes (T2D). This was a single-center, randomized, control, open-labeled trial. Newly diagnosed T2D patients were recruited between February 2014 and December 2015. Subjects were divided into saxagliptin add-on therapy to CSII group (n = 31) and CSII therapy group (n = 38). The treatment was maintained for 4 weeks. Oral glucose tolerance test was performed at baseline. Serum samples were obtained before and 30 and 120 minutes after oral administration for glucose, insulin, and C-peptide determination. Continuous glucose monitoring (CGM) was performed before and endpoint. A total of 69 subjects were admitted. After 4-week therapy, CGM data showed that patients with saxagliptin add-on therapy exhibited further improvement of mean amplitude glycemic excursion (MAGE), the incremental area under curve of plasma glucose >7.8 and 10 mmol/L compared with that of control group. In addition, the hourly mean blood glucose concentrations, especially between 0000 and 0600 in patient with saxagliptin add-on therapy, were significantly lower compared with that of the control patients. Furthermore, patients in saxagliptin add-on group needed lower insulin dose to maintain euglycemic control. In addition, severe hypoglycemic episode was not observed from any group. Saxagliptin add-on therapy to insulin had the ability of further improve blood glycemic controlling, with lower insulin dose required by patients with T2D to maintain euglycemic controlling.

Process for Biotransformation of Androsta-4-ene-3, 17-Dione (4-AD) to Androsta-1,4-Diene-3,17-Dione (ADD).

Androsta-1,4-diene-3,17-dione (androstadienedione, ADD) is key intermediate for the organic synthesis of a variety of female sex hormones such as estrone, estradiol, estriol and other related derivatives. De novo synthesis of this molecule is not yet reported in any form of living system, i.e., microbial, plant, and animal. The structural complexities due to presence of several chiral carbon centers create significant hurdles in chemical synthesis of such molecules. Microbe-mediated biotransformation offer a highly reliable, cost-effective, and relatively non hazardous way for commercial manufacturing of steroidal key intermediates. Currently microbial biotransformations are extensively being exploited for large-scale production of basic intermediates such as androstenedione (AD), ADD, and several types of hydroxylated derivatives of androstane compounds. In this chapter several aspects of microbial biotransformation process of AD to ADD are discussed.

Extensive, selective literature review of 2500 articles from the last years (up to December 2007) predominantly from Medline and Cochrane, using as search terms "antipsychotic or schizophrenia or individual drug names (amisulpride, aripiprazole, clozapine, olanzapine, quetiapine, risperidone, ziprasidone)" and the terms "BMI, weight gain, metabolic syndrome, diabetes, lipid(s), cholesterol, triglycerides" was conducted. Regardless of the advantages ascribed to atypical antipsychotics and the special effectiveness of clozapine in patients resistant to therapy and at risk for suicide, the probability of weight gain is considerably increased for some of these substances. Patients with schizophrenia have a considerably reduced life expectancy associated with an increased prevalence of cardiovascular risk factors. There is a lack of practical guidelines integrated into clinical psychiatric care for the management of cardiovascular risk factors. The monitoring of patients treated with atypics, which has been recommended in the APA/ADA Consensus Paper in light of these facts, is insufficiently established in clinical practice. A regular monitoring can convey self control and motivation to the patient. In the case of corresponding risk constellations further decisions regarding indication and therapy have to be considered. Especially patients with a high cardiovascular risk profile are highly recommended to participate in a weight-management program for prevention purposes. Such a special program should include elements of dietetic treatment and behaviour and exercise therapy. First controlled studies suggest an effective prevention of weight gain and metabolic changes when applying such a structured program. The practice oriented step by step concept presented here is meant to provide points of reference for the implementation of required medical and psychoeducative measures facilitating the management of weight and further cardiovascular risk factors in the context of

To examine pregnant women's weight-related attitudes and behaviors in relation to a constellation of psychosocial characteristics, prepregnancy body habitus, and gestational weight gain. One hundred-thirty women with low-risk, normal pregnancies. Cross-sectional, observational study assessed attitudes about weight gain at 36 weeks' gestation. Psychosocial characteristics, including anxiety, depression, social support, emotionality, and pregnancy-specific and nonspecific stress appraisal were assessed between 28 and 36 weeks' gestation. Principal components factor analysis, Pearson correlations, t tests, and analysis of variance. A range of positive and negative attitudes about weight gain was expressed. Twenty-one percent (n=27) of the sample endorsed at least one weight-restrictive behavior during pregnancy. Women who reported more weight-restrictive behaviors were more anxious (r=.24, P<.01), depressed (r=.29,P<.001), angry (r=.29, P<.001), stressed (r=.23, P<.01), and felt less uplifted (r=-.21, P<.05) about their pregnancies in general. Higher Positive Pregnancy Body Image scores were associated with feeling better about the pregnancy in general (r=.35, P<.001), fewer depressive symptoms, and less anger (both r=.20, both P<.01). Women who were self conscious about their weight gain felt more hassled by their pregnancies (r=.21, P<.05), greater anger (r=.21, P<.05), and more support from partners (r=.22, P<.05). Prepregnancy body mass index was unrelated, but negative attitudes about weight gain existed even among women who gained within recommended ranges. Women's attitudes about weight gain in pregnancy are imbedded in their orientation toward pregnancy as well as their general psychological functioning. Effective nutrition counseling for pregnant women should include consideration of weight-restrictive behaviors, the degree to which the pregnancy is perceived as positive and uplifting, and whether weight gain attitudes may be associated with their

Canagliflozin, a sodium glucose co-transporter 2 (SGLT2) inhibitor, has been associated with weight loss in a broad range of patients with type 2 diabetes mellitus (T2DM). This analysis further evaluated changes in body weight and composition with canagliflozin in two 104-week, Phase 3 studies. In Study 1, patients aged 18-80 years (N = 1,450) received canagliflozin 100 or 300 mg or glimepiride as add-on to metformin for a 52-week core treatment period, followed by a 52-week extension period. In Study 2, patients aged 55-80 years (N = 714) received canagliflozin 100 or 300 mg or placebo added to stable background antihyperglycemic agents for a 26-week core treatment period, followed by a 78-week extension period. Percent change from baseline in body weight; proportion of patients with any weight loss, ≥5% weight loss, and ≥10% weight loss; change in body mass index (BMI) and waist circumference; change in body weight across weight-loss quartiles; and changes in body composition were evaluated in both studies. Canagliflozin 100 and 300 mg provided sustained weight loss versus either glimepiride or placebo over 104 weeks. More patients experienced any weight loss and ≥5% weight loss with canagliflozin versus comparator. Across the 3 highest weight-loss quartiles, canagliflozin provided greater weight loss versus glimepiride or placebo. BMI and waist circumference reductions were observed with canagliflozin 100 and 300 mg versus either glimepiride or placebo over 104 weeks; more patients had BMI or waist circumference reductions with canagliflozin versus comparator. Body composition analysis indicated that the majority of weight loss was due to loss of fat mass. Canagliflozin was generally well tolerated, with increased incidence of adverse events related to the SGLT2 inhibition mechanism. Canagliflozin 100 and 300 mg provided sustained reductions in body weight, BMI, and waist circumference in a greater proportion of patients with T2DM versus

Drawing from self-determination theory (Ryan & Deci, 2002, Overview of self-determination theory: An organismic-dialectical perspective. In E. L. Deci & R. M. Ryan (Eds.), Handbook of self-determination research (pp. 3-33). Rochester, NY: The University of Rochester Press.), we examined how individuals' psychological needs, motivation, and behaviours (i.e., physical activity and eating) associated with weight management could be predicted by perceptions of their important others' supportive and controlling behaviours. Using a cross-sectional survey design, 235 participants (mean age = 27.39 years, SD = 8.96 years) completed an online questionnaire. Statistical analyses showed that when important others were perceived to be more supportive, participants reported higher levels of more optimal forms of motivation for weight management, which in turn predicted more physical activity and healthy eating behaviours. In contrast, when important others were perceived to be controlling, participants reported higher levels of less optimal forms of motivation, which in turn predicted less physical activity and healthy eating behaviours, as well as more unhealthy eating behaviours. Significant indirect effects were also found from perceived support and control from important others to physical activity and eating behaviours, all in the expected directions. The findings support the importance of important others providing support and refraining from controlling behaviours in order to facilitate motivation and behaviours conducive to successful weight management. What is already known on this subject? Autonomy support is related to basic need satisfaction and autonomous motivation in the context of weight management. In turn, these variables are related to adaptive outcomes for weight management. What does this study add? Measurement of perceived controlling behaviours by important others. Measurement of perceived need thwarting. Structural model on how important others affect

One of the key issues identified during investigations of microwave power transmission systems from 1965 to 1976 was the need to assure that the billions of diodes on ground-based rectennas are sufficiently reliable to support long life times of approximately 30 years. Major systems studies conducted focused on waveguides; radio frequency interference and biological considerations; the relationship between performance, weight, and cost; risk assessment; crossed field directional amplifier noise; a 48 kW klystron; effects of the environment on propagation and phase control; rectenna technology; a rationale for the ground power density region; alternate technologies for orbital assembly; ionospheric effects and phase control; and reception conversion (rf to dc collector/converter).

Logistic regression models were used to examine the relationships between measures of weight-related and self-reported suicidal behavior, controlling for demographics, depressive mood, stress perception, level of school achievement, and substance use. Suicide attempts were surveyed among those reported to have suicidal ideation (n = 7,579 boys, 10,204 girls). Significantly more girls than boys reported suicidal ideation (29 vs. 19%) and suicide attempts (7.7 vs. 4.5%). Factors significantly associated with suicidal ideation were overestimation of weight (vs. correct estimation) and behaviors to lose or gain weight (vs. no weight control) among boys and overestimation of weight and attempting to lose weight among girls. In contrast, the odds of suicide attempts were significantly higher among boys who tried to lose, gain, or maintain their weight (vs. no weight control) and girls who underestimated their weight (vs. correct estimation) and tried to lose weight (vs. no weight control). Boys and girls classified as overweight or at risk for overweight were significantly less likely to report suicide attempts compared to those classified as underweight. Weight-related attitudes, such as incorrect weight perception and weight control behaviors, seem to be useful indicators for identifying Korean adolescents who are at risk for suicidal behaviors.

Nanomaterials continue to bring promising advances to science and technology. In concert have come calls for increased regulatory oversight to ensure their appropriate identification and evaluation, which has led to extensive discussions about nanomaterial definitions. Numerous nanomaterial definitions have been proposed by government, industry, and standards organizations. We conducted a comprehensive comparative assessment of existing nanomaterial definitions put forward by governments to highlight their similarities and differences. We found that the size limits used in different definitions were inconsistent, as were considerations of other elements, including agglomerates and aggregates, distributional thresholds, novel properties, and solubility. Other important differences included consideration of number size distributions versus weight distributions and natural versus intentionally-manufactured materials. Overall, the definitions we compared were not in alignment, which may lead to inconsistent identification and evaluation of nanomaterials and could have adverse impacts on commerce and public perceptions of nanotechnology. We recommend a set of considerations that future discussions of nanomaterial definitions should consider for describing materials and assessing their potential for health and environmental impacts using risk-based approaches within existing assessment frameworks. Our intent is to initiate a dialogue aimed at achieving greater clarity in identifying those nanomaterials that may require additional evaluation, not to propose a formal definition.

Patient weight is a key measure for safe medication management and monitoring of patients. Here we report the recording of patient's body weight on admission in three hospitals in West London and its relationship with the prescription of antibiotic drugs where it is essential to have the body weight of the patient. A prospective cross-sectional study was conducted in three teaching hospitals in West London. Data were collected during March 2011-September 2011 and July 2012-August 2012, from adult admissions units, medical and surgical wards. Data from each ward were collected on a single day to provide a point prevalence data on weight recording. Patient medication charts, nursing and medical notes were reviewed for evidence of weight and height recording together with all the medication prescribed for the patients. An observational study collecting data on the weight recording process was conducted on two randomly selected wards to add context to the data. Data were collected on 1012 patients. Weight was not recorded for 46% (474) of patients. Eighty-nine patients were prescribed a narrow therapeutic antibiotic, in 39% (35/89) of these weight was not recorded for the patient. Intravenous vancomycin was the most commonly prescribed antibiotic requiring therapeutic monitoring. In total 61 patients were receiving intravenous vancomycin and of these 44% (27/61) did not have their weight recorded. In the observational study, the most frequently identified barrier to weight not being recorded was interruptions to the admission process. Despite the clinical importance of body weight measurement it is poorly recorded in hospitalised patients, due to interruptions to the workflow and heavy staff workloads. In antibiotics a correct, recent patient weight is required for accurate dosing and to keep drugs within the narrow therapeutic index, to ensure efficacy of prescribing and reduce toxicity.

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.

Geographically Weighted Regression (GWR) is a regression model that takes into account the spatial heterogeneity effect. In the application of the GWR, inference on regression coefficients is often of interest, as is estimation and prediction of the response variable. Empirical research and studies have demonstrated that local correlation between explanatory variables can lead to estimated regression coefficients in GWR that are strongly correlated, a condition named multicollinearity. It later results on a large standard error on estimated regression coefficients, and, hence, problematic for inference on relationships between variables. Geographically Weighted Lasso (GWL) is a method which capable to deal with spatial heterogeneity and local multicollinearity in spatial data sets. GWL is a further development of GWR method, which adds a LASSO (Least Absolute Shrinkage and Selection Operator) constraint in parameter estimation. In this study, GWL will be applied by using fixed exponential kernel weights matrix to establish a poverty modeling of Java Island, Indonesia. The results of applying the GWL to poverty datasets show that this method stabilizes regression coefficients in the presence of multicollinearity and produces lower prediction and estimation error of the response variable than GWR does.

To improve the anti-cancer efficacy and to counteract the side effects of chemotherapy, a variety of drug delivery systems have been invented in past decades, but few of these systems have succeeded in clinical trials due to their respective inherent shortcomings. Recently, low-molecular weight hydrogels of peptides that self-assemble via non-covalent interactions have attracted considerable attention due to their good biocompatibility, low toxicity, inherent biodegradability as well as their convenience of design. Low-molecular weight hydrogels have already shown promise in biomedical applications as diverse as 3D-cell culture, enzyme immobilization, controllable MSC differentiation, wound healing, drug delivery etc. Here we review the recent development in the use of low-molecular weight hydrogels for cancer therapy, which may be helpful in the design of soft materials for drug delivery.

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.

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.

After 23 years of the end of the Iran-Iraq war, the country is left with many patients with chronic posttraumatic stress disorder (PTSD) who need close psychiatric services and are in need for recurrent hospitalization. So far, there are no reports of the rivastigmine use in PTSD patients. We report dramatic reduction of symptoms in 3 veterans with chronic PTSD, after rivastigmine augmentation. This report describes the efficacy of rivastigmine as an add-on to standard treatment of 3 Iranian male veterans with chronic PTSD (aged 52, 46, and 45 years) with severe active symptoms in all 3 dimensions of the disorder. Although they had gone through many approved drug treatments (selective serotonin reuptake inhibitors, tricyclic antidepressants, mood stabilizers, antipsychotics, benzodiazepines, β-blockers, and so on), from the beginning of the disorder, their recovery remained poor (PTSD Checklist-Military Version [PCL-M] scores were 67, 71, and 73 before rivastigmine add-on). Rivastigmine was added to the ongoing therapeutic regimens of the patients for 6 months.Evaluating their condition with PCL-M after 1 and 6 months of treatment showed a significant improvement in patients with PTSD (PCL-M scores were 37, 40, and 47 and dropped to 30, 27, and 31, respectively). Hyperarousal symptoms of PTSD in patients are noted to be the most improved. The rivastigmine add-on experience did not report any adverse effects. The present study showed that rivastigmine is an effective and safe add-on to treatment of patients with chronic PTSD. This effect could be due to improved cognitive status or cholinergic-adrenergic balance adjustment in patients.

The paper presents the weight optimization process of the main steel truss that supports the Slatina Sport Hall roof. The structure was loaded with self-weight, dead loads, live loads, snow, wind and temperature, grouped in eleven load cases. The optimization of the structure was made using genetic algorithms implemented in a Matlab code. A total number of four different cases were taken into consideration when trying to determine the lowest weight of the structure, depending on the types of connections with the concrete structure ( types of supports, bearing modes), and the possibility of the lower truss chord nodes tomore » change their vertical position. A number of restrictions for tension, maximum displacement and buckling were enforced on the elements, and the cross sections are chosen by the program from a user data base. The results in each of the four cases were analyzed in terms of weight, element tension, element section and displacement.

Vehicle weight is an important factor to be maintained for transportation safety. A weight limitation system is proposed to make sure the vehicle weight is always below its designation prior the vehicle is being used by the driver. The proposed system is divided into two systems, namely vehicle weight confirmation system and weight warning system. In vehicle weight confirmation system, the weight sensor work for the first time after the ignition switch is turned on. When the weight is under the weight limit, the starter engine can be switched on to start the engine system, otherwise it will be locked. The seconds system, will operated after checking all the door at close position, once the door of the car is closed, the weight warning system will check once again the weight during runing engine condition. The results of these two systems, vehicle weight confirmation system and weight warning system have 100 % accuracy, respectively. These show that the proposed vehicle weight limitation system operate well.

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.

Background. Weight-loss behaviours are highly prevalent among adolescents, and body weight perception motivates weight control practices. However, little is known about the association of body weight perception, and weight control practices among teenagers in Mauritius. The aim of this study is to investigate the relationships between actual body weight, body weight perception, and weight control practices among teenagers. Methods. A questionnaire-based survey was used to collect data on anthropometric measurements, weight perception and weight control practices from a sample of 180 male and female students (90 boys and 90 girls) aged between 13 and 18 years old. Results. Based on BMI, 11.7% of students were overweight. Overall, 43.3% of respondents reported trying to lose weight (61.1% girls and 25.6% boys). Weight-loss behaviours were more prevalent among girls. Among the weight-loss teens, 88.5% students perceived themselves as overweight even though only 19.2% were overweight. Reducing fat intake (84.6%), exercising (80.8%), and increasing intake of fruits and vegetables (73.1%) and decreasing intake of sugar (66.7%) were the most commonly reported methods to lose weight. Conclusion. Body weight perception was poorly associated with actual weight status. Gender difference was observed in body weight perception. PMID:24967256

Uncertainties of climate projections are routinely assessed by considering simulations from different models. Observations are used to evaluate models, yet there is a debate about whether and how to explicitly weight model projections by agreement with observations. Here we present a straightforward weighting scheme that accounts both for the large differences in model performance and for model interdependencies, and we test reliability in a perfect model setup. We provide weighted multimodel projections of Arctic sea ice and temperature as a case study to demonstrate that, for some questions at least, it is meaningless to treat all models equally. The constrained ensemble shows reduced spread and a more rapid sea ice decline than the unweighted ensemble. We argue that the growing number of models with different characteristics and considerable interdependence finally justifies abandoning strict model democracy, and we provide guidance on when and how this can be achieved robustly.

Structural consequences of disease-causing mutations in the ATRX-DNMT3-DNMT3L (ADD) domain of the chromatin-associated protein ATRX.

The chromatin-associated protein ATRX was originally identified because mutations in the ATRX gene cause a severe form of syndromal X-linked mental retardation associated with alpha-thalassemia. Half of all of the disease-associated missense mutations cluster in a cysteine-rich region in the N terminus of ATRX. This region was named the ATRX-DNMT3-DNMT3L (ADD) domain, based on sequence homology with a family of DNA methyltransferases. Here, we report the solution structure of the ADD domain of ATRX, which consists of an N-terminal GATA-like zinc finger, a plant homeodomain finger, and a long C-terminal alpha-helix that pack together to form a single globular domain. Interestingly, the alpha-helix of the GATA-like finger is exposed and highly basic, suggesting a DNA-binding function for ATRX. The disease-causing mutations fall into two groups: the majority affect buried residues and hence affect the structural integrity of the ADD domain; another group affects a cluster of surface residues, and these are likely to perturb a potential protein interaction site. The effects of individual point mutations on the folding state and stability of the ADD domain correlate well with the levels of mutant ATRX protein in patients, providing insights into the molecular pathophysiology of ATR-X syndrome.

The food-borne pathogen Campylobacter jejuni depends on the AddAB DNA repair system to defend against bile in the intestinal environment.

Accurate repair of DNA damage is crucial to ensure genome stability and cell survival of all organisms. Bile functions as a defensive barrier against intestinal colonization by pathogenic microbes. Campylobacter jejuni, a leading bacterial cause of foodborne illness, possess strategies to mitigate the toxic components of bile. We recently found that growth of C. jejuni in medium with deoxycholate, a component of bile, caused DNA damage consistent with the exposure to reactive oxygen species. We hypothesized that C. jejuni must repair DNA damage caused by reactive oxygen species to restore chromosomal integrity. Our efforts focused on determining the importance of the putative AddAB DNA repair proteins. A C. jejuni addAB mutant demonstrated enhanced sensitivity to deoxycholate and was impaired in DNA double strand break repair. Complementation of the addAB mutant restored resistance to deoxycholate, as well as function of the DNA double strand break repair system. The importance of these findings translated to the natural host, where the AddAB system was found to be required for efficient C. jejuni colonization of the chicken intestine. This research provides new insight into the molecular mechanism utilized by C. jejuni, and possibly other intestinal pathogens, to survive in the presence of bile.

Mechanisms of Weight Regain following Weight Loss.

Obesity is a world-wide pandemic and its incidence is on the rise along with associated comorbidities. Currently, there are few effective therapies to combat obesity. The use of lifestyle modification therapy, namely, improvements in diet and exercise, is preferable over bariatric surgery or pharmacotherapy due to surgical risks and issues with drug efficacy and safety. Although they are initially successful in producing weight loss, such lifestyle intervention strategies are generally unsuccessful in achieving long-term weight maintenance, with the vast majority of obese patients regaining their lost weight during followup. Recently, various compensatory mechanisms have been elucidated by which the body may oppose new weight loss, and this compensation may result in weight regain back to the obese baseline. The present review summarizes the available evidence on these compensatory mechanisms, with a focus on weight loss-induced changes in energy expenditure, neuroendocrine pathways, nutrient metabolism, and gut physiology. These findings have added a major focus to the field of antiobesity research. In addition to investigating pathways that induce weight loss, the present work also focuses on pathways that may instead prevent weight regain. Such strategies will be necessary for improving long-term weight loss maintenance and outcomes for patients who struggle with obesity.

The aim of the present study was to standardize and generate psychometric evidence of the German language versions of two well-established English language mental health instruments: the Aberrant Behavior Checklist-Community (ABC-C) and the Psychiatric Assessment Schedule for Adults with Developmental Disabilities (PAS-ADD) Checklist. New methods in this field were introduced: a simulation method for testing the factor structure and an exploration of long-term stability over two years. The checklists were both administered to a representative sample of 270 individuals with intellectual disability (ID) and, two years later in a second data collection, to 128 participants of the original sample. Principal component analysis and parallel analysis were performed. Reliability measures, long-term stability, subscale intercorrelations, as well as standardized norms were generated. Prevalence of mental health problems was examined. Psychometric properties were mostly excellent, with long-term stability showing moderate to strong effects. The original factor structure of the ABC-C was replicated. PAS-ADD Checklist produced a similar, but still different structure compared with findings from the English language area. The overall prevalence rate of mental health problems in the sample was about 20%. Considering the good results on the measured psychometric properties, the two checklists are recommended for the early detection of mental health problems in persons with ID.

The defence of body weight: a physiological basis for weight regain after weight loss.

PubMed

Sumithran, Priya; Proietto, Joseph

2013-02-01

Although weight loss can usually be achieved by restricting food intake, the majority of dieters regain weight over the long-term. In the hypothalamus, hormonal signals from the gastrointestinal tract, adipose tissue and other peripheral sites are integrated to influence appetite and energy expenditure. Diet-induced weight loss is accompanied by several physiological changes which encourage weight regain, including alterations in energy expenditure, substrate metabolism and hormone pathways involved in appetite regulation, many of which persist beyond the initial weight loss period. Safe effective long-term strategies to overcome these physiological changes are needed to help facilitate maintenance of weight loss. The present review, which focuses on data from human studies, begins with an outline of body weight regulation to provide the context for the subsequent discussion of short- and long-term physiological changes which accompany diet-induced weight loss.

Posttraumatic stress disorder (PTSD) is a chronic disabling illness, resulting from exposure to extreme traumatic event. Although different pharmacologic agents are suggested for treatment of PTSD, none have been completely effective in eliminating symptoms. The purpose of this study was to assess the use of baclofen as an add-on to citalopram in treatment of PTSD. In this double-blind clinical trial, 40 Iranian combat veterans with PTSD were randomly assigned to 2 groups. The first group received a combination treatment of 20 to 60 mg/d citalopram and 40 mg/d baclofen, and the second group received 20 to 60 mg/d citalopram plus placebo. Symptom severity was assessed by Clinician-Administered PTSD Scale at the beginning of the study and after 2, 4, 6, and 8 weeks. Global Assessment of Functioning and Hamilton Rating Scale for Anxiety and Depression were also used at the same periods. Data were analyzed with independent t test and paired t test using SPSS software version 13 (IBM, Armonk, NY). Twenty-three male patients (baclofen group, 13 patients; placebo group, 10 patients) completed the study. Dropout from the treatment was not caused by adverse effects of the new medications in any of the subjects. Baclofen group showed significantly larger improvement in Clinician-Administered PTSD Scale total (P = 0.040), hyperarousal (P = 0.020), and avoidance (0.020) scores, Global Assessment of Functioning score (0.001), depression (P = 0.000), and anxiety (P = 0.000) after 8 weeks of treatment. No intergroup difference was found in improvement of reexperience symptoms (P = 0.740). Baclofen showed to be an effective add-on to selective serotonin reuptake inhibitors in treatment of PTSD for better symptom recovery and functional improvement.

Development of high frequency low weight power magnetics for aerospace power systems

A dominant design consideration in the development of space type power mangetic devices is the application of reliable thermal control methods to prevent device failure which is due to excessive temperature rises and hot temperatures in critical areas. The resultant design must also yield low weight, high efficiency, high reliability and maintainability, and long life. The weight savings and high efficiency that results by going to high frequency and unique thermal control techniques is demonstrated by the development of a 25 kVA, 20 kHz space type transformer under the power magnetics technology program. Work in the area of power rotary transformer is also discussed.

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.

Weighting of NMME temperature and precipitation forecasts across Europe

Multi-model ensemble forecasts are obtained by weighting multiple General Circulation Model (GCM) outputs to heighten forecast skill and reduce uncertainties. The North American Multi-Model Ensemble (NMME) project facilitates the development of such multi-model forecasting schemes by providing publicly-available hindcasts and forecasts online. Here, temperature and precipitation forecasts are enhanced by leveraging the strengths of eight NMME GCMs (CCSM3, CCSM4, CanCM3, CanCM4, CFSv2, GEOS5, GFDL2.1, and FLORb01) across all forecast months and lead times, for four broad climatic European regions: Temperate, Mediterranean, Humid-Continental and Subarctic-Polar. We compare five different approaches to multi-model weighting based on the equally weighted eight single-model ensembles (EW-8), Bayesian updating (BU) of the eight single-model ensembles (BU-8), BU of the 94 model members (BU-94), BU of the principal components of the eight single-model ensembles (BU-PCA-8) and BU of the principal components of the 94 model members (BU-PCA-94). We assess the forecasting skill of these five multi-models and evaluate their ability to predict some of the costliest historical droughts and floods in recent decades. Results indicate that the simplest approach based on EW-8 preserves model skill, but has considerable biases. The BU and BU-PCA approaches reduce the unconditional biases and negative skill in the forecasts considerably, but they can also sometimes diminish the positive skill in the original forecasts. The BU-PCA models tend to produce lower conditional biases than the BU models and have more homogeneous skill than the other multi-models, but with some loss of skill. The use of 94 NMME model members does not present significant benefits over the use of the 8 single model ensembles. These findings may provide valuable insights for the development of skillful, operational multi-model forecasting systems.

Birth weight percentiles by gestational age are important for assessing prenatal growth and predicting postnatal outcomes of newborns. Several countries have developed nation-specific birth weight references for twins, but China still lacks such references. Birth weight data for twins born between October 2006 and September 2015 were abstracted from the China National Population-based Birth Defects Surveillance System. A total of 54,786 live twin births aged ≥28 weeks of gestation without birth defects were included in the analysis. The LMS method was adopted to generate gestational age-specific birth weight percentiles and curves for male and female twins separately. Significant differences were observed between the current reference and other references developed for Chinese or non-Chinese twins. The neonatal mortality rate in this cohort was 12.3‰, and much higher rates at very early gestation weeks were identified in small-for-gestational-age twins grouped by the newly developed reference cutoffs. The established birth weight centiles represent the first birth weight norm for contemporary Chinese twins and can be a useful tool to assess growth of twins in clinical and research settings. Key Messages There have been no population-based birth weight percentiles for Chinese twins prior to this study. The established birth weight centiles for female and male twins are markedly lower than those for Chinese singletons. Twin-specific curves should be used for determining inappropriate for gestational age in twins rather than using existing singleton reference. The birth weight percentiles for twins differed significantly from those for non-Chinese twins. In addition to ethnic influences, the observed differences could be ascribed to variations in prenatal care, fetal or maternal nutrition status or other environmental factors. Neonatal mortality rates varied considerably among twins grouped by the newly developed reference percentiles. Small

Objectives To examine the combined effect of social class and weight at birth on cognitive trajectories during school age and the associations between birth weight and educational outcomes through to 33 years. Design Longitudinal, population based, birth cohort study. Participants 10 845 males and females born during 3-9 March 1958 with information on birth weight, social class, and cognitive tests. Main outcome measures Reading, maths, draw a man, copying designs, verbal and non-verbal ability tests at ages 7, 11, and 16, highest qualifications achieved by 33, and trajectories of maths standardised scores at 7-16 years. Results The outcome of all childhood cognitive tests and educational achievements improved significantly with increasing birth weight. Analysis of maths scores at 7 and of highest qualifications achieved by 33 showed that the relations were robust to adjustment for potential confounding factors. For each kilogram increase in birth weight, maths z score increased by 0.17 (adjusted estimate 0.15, 95% confidence interval 0.10 to 0.21) for males and 0.21 (0.20, 0.14 to 0.25) for females. Trajectories of maths z scores between 7 and 16 years diverged for different social class groups: participants from classes I and II increased their relative position on the score with increasing age, whereas classes IV and V showed a relative decline with increasing age. Birth weight explained much less of the variation in cognition than did social class (range 0.5-1.5% v 2.9-12.5%). Conclusions The postnatal environment has an overwhelming influence on cognitive function through to early adulthood, but these strong effects do not explain the weaker but independent association with birth weight. What is already known on this topicWeight at birth is associated with later cognitive developmentThis is maintained across the range of normal birth weightsWhat this study addsSocial class at birth and birth weight have independent effects on maths scores in childhood, but

Diet and exercise for weight loss: a review of current issues.

2005-01-01

Obesity is a fast growing epidemic that is primarily due to environmental influences. Nutrition and exercise represent modifiable factors with a major impact on energy balance. Despite considerable research, there remains continued debate regarding the energy content and the optimal macronutrient distribution for promoting healthy and effective weight loss. Low-fat diets have been advised for many years to reduce obesity. However, their effectiveness has been recently challenged, partly because the prevalence of obesity continues to rise despite reductions in fat intake. There are also concerns regarding the methodology of clinical trials showing benefits of fat reduction on weight loss. Although often viewed as a fad diet, very low-carbohydrate (ketogenic) diets are very popular and several recent clinical trials indicate they are more effective at promoting short-term weight loss and improving characteristics of the metabolic syndrome than low-fat diets. However, there is a need to obtain long-term safety and efficacy data. Clearly, weight loss can be achieved with a variety of diet interventions but the effects on other health-related aspects also need to be considered and studied in more detail. Exercise can have positive effects on weight loss, weight control and overall general health, although debate exists concerning the most effective mode, duration and intensity of exercise required to achieve these effects. Importantly, any effective weight control treatment must consider a life-long plan or there will likely be weight regain. Perhaps the most challenging, but rewarding, question that faces researchers is how to predict individual responses to diet and exercise interventions.

Average Weighted Receiving Time of Weighted Tetrahedron Koch Networks

We introduce weighted tetrahedron Koch networks with infinite weight factors, which are generalization of finite ones. The term of weighted time is firstly defined in this literature. The mean weighted first-passing time (MWFPT) and the average weighted receiving time (AWRT) are defined by weighted time accordingly. We study the AWRT with weight-dependent walk. Results show that the AWRT for a nontrivial weight factor sequence grows sublinearly with the network order. To investigate the reason of sublinearity, the average receiving time (ART) for four cases are discussed.

No prior research has been done with normal weight persons specific to their experience of weight management. The purpose of this research was to discover the experience of weight management in normal weight individuals. Glaserian grounded theory was used. Qualitative data (focus group) and quantitative data (food diary, study questionnaire, and anthropometric measures) were collected. Weight management was an ongoing process of trying to focus on living (family, work, and social), while maintaining their normal weight targets through five consciously and unconsciously used strategies. Despite maintaining normal weights, the nutritional composition of foods eaten was grossly inadequate. These five strategies can be used to develop new weight management strategies that could be integrated into existing weight management programs, or could be developed into novel weight management interventions. Surprisingly, normal weight individuals require dietary assessment and nutrition education to prevent future negative health consequences. Copyright © 2016 Elsevier Inc. All rights reserved.

Comparisons of the weight and the value of production of a type of gemstone between countries may differ considerably. Whereas east African countries dominate the weight production of rubies, Burma (Myanmar) is widely thought to have the highest value of ruby production. Data on the value of gemstone production are even more difficult to estimate than is the weight of production. Value of production is dependent upon both the quality and the sizes of the stones produced. Such data are not readily available and are difficult to estimate; therefore this report does not present tables of values of production. Instead, the report briefly discusses the forms in which gemstones are sold, the systems used to value the gemstones, and selected data that illustrate the variability of value of gemstones of a particular type.

Multifractal analysis and topological properties of a new family of weighted Koch networks

Weighted complex networks, especially scale-free networks, which characterize real-life systems better than non-weighted networks, have attracted considerable interest in recent years. Studies on the multifractality of weighted complex networks are still to be undertaken. In this paper, inspired by the concepts of Koch networks and Koch island, we propose a new family of weighted Koch networks, and investigate their multifractal behavior and topological properties. We find some key topological properties of the new networks: their vertex cumulative strength has a power-law distribution; there is a power-law relationship between their topological degree and weight strength; the networks have a high weighted clustering coefficient of 0.41004 (which is independent of the scaling factor c) in the limit of large generation t; the second smallest eigenvalue μ2 and the maximum eigenvalue μn are approximated by quartic polynomials of the scaling factor c for the general Laplacian operator, while μ2 is approximately a quartic polynomial of c and μn= 1.5 for the normalized Laplacian operator. Then, we find that weighted koch networks are both fractal and multifractal, their fractal dimension is influenced by the scaling factor c. We also apply these analyses to six real-world networks, and find that the multifractality in three of them are strong.

Handling Dynamic Weights in Weighted Frequent Pattern Mining

NASA Astrophysics Data System (ADS)

Ahmed, Chowdhury Farhan; Tanbeer, Syed Khairuzzaman; Jeong, Byeong-Soo; Lee, Young-Koo

Even though weighted frequent pattern (WFP) mining is more effective than traditional frequent pattern mining because it can consider different semantic significances (weights) of items, existing WFP algorithms assume that each item has a fixed weight. But in real world scenarios, the weight (price or significance) of an item can vary with time. Reflecting these changes in item weight is necessary in several mining applications, such as retail market data analysis and web click stream analysis. In this paper, we introduce the concept of a dynamic weight for each item, and propose an algorithm, DWFPM (dynamic weighted frequent pattern mining), that makes use of this concept. Our algorithm can address situations where the weight (price or significance) of an item varies dynamically. It exploits a pattern growth mining technique to avoid the level-wise candidate set generation-and-test methodology. Furthermore, it requires only one database scan, so it is eligible for use in stream data mining. An extensive performance analysis shows that our algorithm is efficient and scalable for WFP mining using dynamic weights.

Opportunities for Intervention Strategies for Weight Management: Global Actions on Fluid Intake Patterns

2015-01-01

Water is an essential nutrient for all physiological functions and particularly important for thermoregulation. About 60% of our body weight is made of water. Under standard conditions (18-20 °C and moderate activity), water balance is regulated within 0.2 % of body weight over a 24-hour period. Water requirement varies between individuals and according to environmental conditions. Concerning considerations related to obesity, the health impact of fluid intake is commonly overlooked. Fluid intake advices are missing in most of food pyramids offered to the public, and water requirements and hydration challenges remain often neglected. The purpose of this paper is to emphasize and discuss the role of water consumption in the context of other important public health measures for weight management. Attention will be focused on fluid intake patterns and hydration-related questions in the context of global interventions and/or physical activity programs settled in weight management protocols.

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.

Body image concerns in binge eating disorder (BED) have been examined almost exclusively in overweight individuals with BED. The current study extends past research by including overweight and normal weight BED and non-BED groups to assess the multifactorial construct of body image using subscales of the Eating Disorder Examination 16.0 (EDE-16.0) and a Body Comparison Task. Independent of weight status and when controlling for age and race, women with BED are distinguished from those without BED by significantly greater overvaluation of shape and weight on the EDE-16.0 and significantly reduced weight satisfaction after a Body Comparison Task. Both BED diagnosis and weight status were independently associated with Weight Concern and Shape Concern subscales on the EDE-16.0. Taken together, these data provide further support for the consideration of body image concerns in the diagnostic criteria for BED. Copyright © 2017 Elsevier Ltd. All rights reserved.

To validate clinic weights in electronic health records against researcher-measured weights for outcome assessment in weight loss trials. Clinic and researcher-measured weights from a published trial (BE WELL) were compared using Lin's concordance correlation coefficient, Bland and Altman's limits of agreement, and polynomial regression model. Changes in clinic and researcher-measured weights in BE WELL and another trial, E-LITE, were analyzed using growth curve modeling. Among BE WELL (n = 330) and E-LITE (n = 241) participants, 96% and 90% had clinic weights (mean [SD] of 5.8 [6.1] and 3.7 [3.9] records) over 12 and 15 months of follow-up, respectively. The concordance correlation coefficient was 0.99, and limits of agreement plots showed no pattern between or within treatment groups, suggesting overall good agreement between researcher-measured and nearest-in-time clinic weights up to 3 months. The 95% confidence intervals for predicted percent differences fell within ±3% for clinic weights within 3 months of the researcher-measured weights. Furthermore, the growth curve slopes for clinic and researcher-measured weights by treatment group did not differ significantly, suggesting similar inferences about treatment effects over time, in both trials. Compared with researcher-measured weights, close-in-time clinic weights showed high agreement and inference validity. Clinic weights could be a valid pragmatic outcome measure in weight loss studies. © 2017 The Obesity Society.

No global consensus: a cross-sectional survey of maternal weight policies

PubMed Central

2014-01-01

Background Growing evidence suggests that maternal prepregnancy weight and gestational weight gain are risk factors for perinatal complications and subsequent maternal and child health. Postpartum weight retention is also associated with adverse birth outcomes and maternal obesity. Clinical guidelines addressing healthy weight before, during, and after pregnancy have been introduced in some countries, but at present a systematic accounting for these policies has not been conducted. The objective of the present study was to conduct a cross-national comparison of maternal weight guidelines. Methods This cross sectional survey administered a questionnaire online to key informants with expertise on the subject of maternal weight to assess the presence and content of preconceptional, pregnancy and postpartum maternal weight guidelines, their rationale and availability. We searched 195 countries, identified potential informants in 80 and received surveys representing 66 countries. We estimated the proportion of countries with guidelines by region, income, and formal or informal policy, and described and compared guideline content, including a rubric to assess presence or absence of 4 guidelines: encourage healthy preconceptional weight, antenatal weighing, encourage appropriate gestational gain, and encourage attainment of healthy postpartum weight. Results Fifty-three countries reported either a formal or informal policy regarding maternal weight. The majority of these policies included guidelines to assess maternal weight at the first prenatal visit (90%), to monitor gestational weight gain during pregnancy (81%), and to provide recommendations to women about healthy gestational weight gain (62%). Guidelines related to preconceptional (42%) and postpartum (13%) weight were less common. Only 8% of countries reported policies that included all 4 fundamental guidelines. Guideline content and rationale varied considerably between countries, and respondents perceived that

Unrealistic expectations about weight goal and about weight loss-related benefits can hinder the effort for a successful long-term weight control. To explore weight loss-related goals and their background among overweight/obese patients. Study sample consisted of patients who participated in the inpatient weight loss treatment in the Lipidological Department of Szent Imre Hospital (n = 339, 19% men). Mean age: 50.2 years (SD = 13.47 years), mean BMI: 38.6 (SD = 7.58). self-reported anthropometric data, type and number of treated illnesses, Goals and Relative Weights Questionnaire, Motivations for Weight Loss Scale, Body Shape Questionnaire. Participants would feel disappointed with a possible 10% weight loss in a half-year time span. The acceptable weight loss percentage was higher among women, younger participants and among those who had more excess weight. Motivation regarding the increase in social desirability by weight loss is in association with body dissatisfaction, health related motivation is in association with the number of treated illnesses. Our results are contributing to the understanding of motivational factors behind weight reduction efforts, considering these can improve treatment success rates. Orv Hetil. 2017; 158(49): 1960-1967.

Weighted network analysis of high-frequency cross-correlation measures

2007-03-01

In this paper we implement a Fourier method to estimate high-frequency correlation matrices from small data sets. The Fourier estimates are shown to be considerably less noisy than the standard Pearson correlation measures and thus capable of detecting subtle changes in correlation matrices with just a month of data. The evolution of correlation at different time scales is analyzed from the full correlation matrix and its minimum spanning tree representation. The analysis is performed by implementing measures from the theory of random weighted networks.

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.

Effect of clothing weight on body weight.

2013-01-01

In clinical settings, it is common to measure weight of clothed patients and estimate a correction for the weight of clothing, but we can find no papers in the medical literature regarding the variability in clothing weight of adults with weather, season and gender. Fifty adults (35 women) were weighed four times during a 12-month period with and without clothing. Clothing weights were determined and regressed against minimum, maximum and average daily outdoor temperature. The average clothing weight (±s.d.) throughout the year was significantly greater in men than in women (1.2±0.3 vs 0.8±0.3 kg, P<0.0001). The average within-person minimum and the average within-person maximum clothing weights across the year were 0.9±0.2 and 1.5±0.4 kg for men, and 0.5±0.2 and 1.1±0.4 kg for women, respectively. The within-person s.d. in clothing weight was 0.3 kg for both men and women. Over the 55 °C range in the lowest to the highest outdoor temperatures, the regressions predicted a maximal change in clothing weight of only 0.4 kg in women and 0.6 kg in men. The clothing weight of men is significantly greater than that of women, but there is little variability throughout the year. Therefore, a clothing adjustment of approximately 0.8 kg for women and 1.2 kg for men is appropriate regardless of outdoor temperature.

Price-Weight Relationships of General Aviation, Helicopters, Transport Aircraft and Engines

NASA Technical Reports Server (NTRS)

Anderson, Joseph L.

1981-01-01

The NASA must assess its aeronautical research program with economic as well as performance measures. It thus is interested in what price a new technology aircraft would carry to make it attractive to the buyer. But what price a given airplane or helicopter will carry is largely a reflection of the manufacturer's assessment of the competitive market into which the new aircraft will be introduced. The manufacturer must weigh any new aerodynamic or system technology innovation he would add to an aircraft by the impact of this innovation upon the aircraft's cost to manufacture, economic attractiveness and price. The intent of this paper is to give price standards against which new technologies and the NASA's research program can be assessed. Using reported prices for sailplanes, general aviation, agriculture, helicopter, business and transport aircraft, price estimating relations in terms of engine and airframe characteristics have been developed. The relations are given in terms of the aircraft type, its manufactured empty weight, engine weight, horsepower or thrust. Factors for the effects of inflation are included to aid in making predictions of future aircraft prices. There are discussions of aircraft price in terms of number of passenger seats, airplane size and research and development costs related to an aircraft model, and indirectly how new technologies, aircraft complexity and inflation have affected these.

Quantification of emissions from knapsack sprayers: 'the weight method

Garcia-Santos, Glenda; Binder, Claudia R.

Misuse of pesticides kill or seriously sicken thousands of people every year and poison the natural environment. Investigations of occupational and environmental risk have received considerable interest over the last decades. And yet, lack of staff and analytical equipments as well the costs of chemical analyses make difficult, if not impossible, the control of the pesticide contamination and residues in humans, air, water, and soils in developing countries. To assess emissions of pesticides (transport and deposition) during spray application and the risk for the human health and the environment, tracers can be useful tools. Uranine was used to quantify drift airborne and later deposition on the neighbouring field and clothes of the applicator after spraying with a knapsack sprayer in one of the biggest areas of potato production in Colombia. Keeping the same setup the amount of wet drift was measured by difference in the weight of high absorbent papers used to collect the tracer. Surprisingly this weight method (Weight-HAP) was able to explain 71% of the drift variance measured with the tracer. Therefore the weight method is presented as a suitable rapid low cost screening tool, complementary to toxicological tests, to assess air pollution, occupational and environmental exposure generated by the emissions from knapsack sprayers during pesticide application. This technique might be important in places were there is lack of analytical instruments.

In order to estimate the uncertainty of the radiation risk associated with the photon energy in epidemiological studies, photon-fluence-weighted LET values were quantified for photon radiation fields with the target organs and irradiation conditions taken into consideration. The photon fluences giving a unit absorbed dose to the target organ were estimated by using photon energy spectra together with the dose conversion coefficients given in ICRP Publication 116 for the target organs of the colon, bone marrow, stomach, lung, skin and breast with three irradiation geometries. As a result, it was demonstrated that the weighted LET values did not show a clear difference among the photon radiation fields subjected to epidemiological studies, regardless of the target organ and the irradiation geometry.

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.

The early signs of obesity are observable in early childhood. Although the most promising prevention approaches are family centered, few relevant early prevention programs exist. This study evaluated the effects of an evidence-based, home-visiting intervention, the Family Check-Up (FCU), on the trajectory of children’s weight gain. The FCU was designed to prevent the development of behavior problems by improving family management practices; children’s weight has not been an explicit target. On the basis of previous research and conceptual models, we hypothesized that intervention effects on parenting practices, specifically caregivers’ use of positive behavior support (PBS) strategies in toddlerhood, would mediate improvements in children’s weight trajectories. A total of 731 indigent caregiver–child dyads from a multisite randomized intervention trial were examined. Observational assessment of parenting and mealtime behaviors occurred from age 2 to 5. The child’s body mass index (BMI) was assessed yearly from age 5 to 9.5. Path analysis with a latent growth model revealed a significant indirect effect of the FCU on the trajectory of BMI in later childhood. Improvements in caregivers’ PBS in toddlerhood, which was related to the nutritional quality of the meals caregivers served to the child during the mealtime task, served as the intervening process. Further, findings indicate that the FCU prevents progression to overweight and obese status amongst at-risk children. These study results add to existing evidence that has demonstrated that family-based interventions aimed at improving general family management skills are effective at preventing weight gain. Future directions are discussed. PMID:25263212

The postpartum period is a vulnerable time for excess weight retention, particularly for the increasing number of women who are overweight at the start of their pregnancy and subsequently find it difficult to lose additional weight gained during pregnancy. Although postpartum weight management interventions play an important role in breaking this potentially vicious cycle of weight gain, the effectiveness of such interventions in breastfeeding women remains unclear. Our aim was to systematically review the literature about the effectiveness of weight management interventions in breastfeeding women. Seven electronic databases were searched for eligible papers. Intervention studies included were carried out exclusively in breastfeeding mothers, ≤2 years postpartum and with a body mass index greater than 18.5 kg/m(2) , with an outcome measure of change in weight and/or body composition. Six studies met the selection criteria, and were stratified according to the type of intervention and outcome measures. Despite considerable heterogeneity among studies, the dietary-based intervention studies appeared to be the most efficacious in promoting weight loss; however, few studies were tailored toward the needs of breastfeeding women. Weight management interventions which include an energy-restricted diet may play a key role in successful postpartum weight loss for breastfeeding mothers. © 2014 Wiley Periodicals, Inc.

Simulation of divot weight in the insulating foam, associated with the external tank of the U.S. space shuttle, has been evaluated using least squares and neural network concepts. The simulation required models based on fundamental considerations that can be used to predict under what conditions voids form, the size of the voids, and subsequent divot ejection mechanisms. The quadratic neural networks were found to be satisfactory for the simulation of foam divot weight in various tests associated with the external tank. Both linear least squares method and the nonlinear neural network predicted identical results.

Feeding styles and child weight status among recent immigrant mother-child dyads

PubMed Central

2012-01-01

Background Research has shown that parental feeding styles may influence children’s food consumption, energy intake, and ultimately, weight status. We examine this relationship, among recent immigrants to the US. Given that immigrant parents and children are at greater risk for becoming overweight/obese with increased time in the US, identification of risk factors for weight gain is critical. Methods Baseline data was collected on 383 mother-child dyads enrolled in Live Well, a community-based, participatory, randomized controlled lifestyle intervention to prevent weight gain in recent immigrant mothers. Socio-demographic information together with heights and weights were collected for both mother and child. Acculturation, behavioral data, and responses to the Caregiver’s Feeding Styles Questionnaire (CFSQ) were also obtained from the mother. Results The children’s average age was 6.2 ± 2.7 years, 58% male. Mothers had been in the country for an average of 6.0 ± 3.3 years, and are Brazilian (36%), Haitian (34%) and Latino (30%). Seventy-two percent of the mothers were overweight/obese, while 43% of the children were overweight/obese. Fifteen percent of mothers reported their feeding style as being high demanding/high responsive; 32% as being high demanding/low responsive; 34% as being low demanding/high responsive and 18% as being low demanding/low responsive. In bivariate analyses, feeding styles significantly differed by child BMIz-score, ethnic group, and mother’s perceived stress. In multiple linear regression, a low demanding/high responsive feeding style was found to be positively associated (ß = 0.56) with a higher child weight as compared to high demanding/high responsive, controlling for known covariates (p = 0.01). Conclusions Most mothers report having a low demanding/high responsive feeding style, which is associated with higher child weight status in this diverse immigrant population. This finding adds to the growing literature that suggests

To review the criteria and 'other' considerations used internationally for prioritizing new health technologies, and to demonstrate a conjoint-analysis methodology (also known as discrete choice experiments) for deriving relative weights for the criteria. We searched the literature for criteria and other considerations for prioritizing new technologies. A convenience sample of 74 respondents completed a conjoint-analysis survey involving criteria related to technologies' 'benefits'. Encompassing 11 countries and the US state of Oregon, we were able to distinguish three main groups of criteria: (a) Need, appropriateness and clinical benefits; (b) Efficiency (including cost-effectiveness); and (c) Equality, solidarity and other ethical or social values. For several countries, the quality of the clinical and economic evidence and factors related to strategic issues and procedural justice respectively are also considered. The criteria and their weights from the conjoint-analysis survey are: 'Lives saved'=0.343, 'Life-prolongation benefits'=0.243, 'Quality-of-life gains'=0.217, a criterion representing the availability of alternative treatments=0.107, and 'Other important social/ethical benefits'=0.087. The criteria represent a pluralistic combination of needs-based, maximizing and egalitarian principles, and we demonstrated a methodology for deriving the weights for criteria related to technologies' 'benefits'.

To describe key behaviors reported by participants in the Portuguese Weight Control Registry and to determine associations between these behaviors and weight loss maintenance. A total of 388 adults participated in this cross-sectional study. Assessments included demographic information, weight history, weight loss and weight maintenance strategies, dietary intake, and physical activity. Participants lost on average 18 kg, which they had maintained for ~28 months. Their average dietary intake was 2199 kcal/day, with 33 % of energy coming from fat. About 78 % of participants engaged in levels of moderate-plus-vigorous physical activity exceeding 150 min/week (51 % above 250 min/week), with men accumulating 82 more minutes than women (p < 0.05). The most frequently reported strategies for both weight loss and maintenance were keeping healthy foods at home, consuming vegetables regularly, and having daily breakfast. Greater weight loss maintenance was associated with higher levels of physical activity, walking, weight self-monitoring, establishing specific goals, and with reduced portion size use, reduced consumption of carbohydrates, and increased consumption of protein, (p < 0.05). Results indicate that weight loss maintenance is possible through the adoption of a nutritionally-balanced diet and regular participation in physical activity, but also suggest that adopting different (and, to a degree, individualized) set of behavioral strategies is key for achieving success.

Review of disability weight studies: comparison of methodological choices and values

PubMed Central

2014-01-01

Introduction The disability-adjusted life year (DALY) is widely used to assess the burden of different health problems and risk factors. The disability weight, a value anchored between 0 (perfect health) and 1 (equivalent to death), is necessary to estimate the disability component (years lived with disability, YLDs) of the DALY. After publication of the ground-breaking Global Burden of Disease (GBD) 1996, alternative sets of disability weights have been developed over the past 16 years, each using different approaches with regards to the panel, health state description, and valuation methods. The objective of this study was to review all studies that developed disability weights and to critically assess the methodological design choices (health state and time description, panel composition, and valuation method). Furthermore, disability weights of eight specific conditions were compared. Methods Disability weights studies (1990¿2012) in international peer-reviewed journals and grey literature were identified with main inclusion criteria being that the study assessed DALY disability weights for several conditions or a specific group of illnesses. Studies were collated by design and methods and evaluation of results. Results Twenty-two studies met the inclusion criteria of our review. There is considerable variation in methods used to derive disability weights, although most studies used a disease-specific description of the health state, a panel that consisted of medical experts, and nonpreference-based valuation method to assess the values for the majority of the disability weights. Comparisons of disability weights across 15 specific disease and injury groups showed that the subdivision of a disease into separate health states (stages) differed markedly across studies. Additionally, weights for similar health states differed, particularly in the case of mild diseases, for which the disability weight differed by a factor of two or more. Conclusions In terms of

Selecting an Architecture for a Safety-Critical Distributed Computer System with Power, Weight and Cost Considerations

2014-01-01

This report presents an example of the application of multi-criteria decision analysis to the selection of an architecture for a safety-critical distributed computer system. The design problem includes constraints on minimum system availability and integrity, and the decision is based on the optimal balance of power, weight and cost. The analysis process includes the generation of alternative architectures, evaluation of individual decision criteria, and the selection of an alternative based on overall value. In this example presented here, iterative application of the quantitative evaluation process made it possible to deliberately generate an alternative architecture that is superior to all others regardless of the relative importance of cost.

While physical exercise as adjunctive treatment for major depression has received considerable attention in recent years, the evidence is conflicting. This study evaluates the effects of two different add-on treatments: exercise and basic body awareness therapy. Randomized controlled trial with two intervention groups and one control, including 62 adults on antidepressant medication, who fulfilled criteria for current major depression as determined by the Mini International Neuropsychiatric Interview. Interventions (10 weeks) were aerobic exercise or basic body awareness therapy (BBAT), compared to a single consultation with advice on physical activity. Primary outcome was depression severity, rated by a blinded assessor using the Montgomery Asberg Rating Scale (MADRS). Secondary outcomes were global function, cardiovascular fitness, self-rated depression, anxiety and body awareness. Improvements in MADRS score (mean change=-10.3, 95% CI (-13.5 to -7.1), p=0.038) and cardiovascular fitness (mean change=2.4ml oxygen/kg/min, 95% CI (1.5 to 3.3), p=0.017) were observed in the exercise group. Per-protocol analysis confirmed the effects of exercise, and indicated that BBAT has an effect on self-rated depression. The small sample size and the challenge of missing data. Participants׳ positive expectations regarding the exercise intervention need to be considered. Exercise in a physical therapy setting seems to have effect on depression severity and fitness, in major depression. Our findings suggest that physical therapy can be a viable clinical strategy to inspire and guide persons with major depression to exercise. More research is needed to clarify the effects of basic body awareness therapy. Copyright © 2014 Elsevier B.V. All rights reserved.

Does smoking affect body weight and obesity in China?

PubMed

Fang, Hai; Ali, Mir M; Rizzo, John A

2009-12-01

An inverse relationship between smoking and body weight has been documented in the medical literature, but the effect of cigarette smoking on obesity remains inconclusive. In addition, the evidence is mixed on whether rising obesity rates are an unintended consequence of successful anti-smoking policies. This study re-examines these relationships using data from China, the largest consumer and manufacturer of tobacco in the world that is also experiencing a steady rise in obesity rates. We focus on the impact of the total number of cigarettes smoked per day on individuals' body mass index (BMI) and on the likelihood of being overweight and obese. Instrumental variables estimation is used to correct for the endogeneity of cigarette smoking. We find a moderate negative and significant relationship between cigarette smoking and BMI. Smoking is also negatively related to being overweight and obese, but the marginal effects are small and statistically insignificant for being obese. Quantile regression analyses reveal that the association between smoking and BMI is quite weak among subjects whose BMIs are at the high end of the distribution but are considerably stronger among subjects in the healthy weight range. Ordered probit regression analyses also confirm these findings. Our results thus reconcile an inverse average effect of smoking on body weight with the absence of any significant effect on obesity. From a policy perspective these findings suggest that, while smoking cessation may lead to moderate weight gain among subjects of healthy weight, the effects on obese subjects are modest and should not be expected to lead to a large increase in obesity prevalence rates.

This study examined the mediating function of body weight perception (BWP) in the relation between body mass index (BMI) and unhealthy weight control behaviors (UWCBs; eg, fasting, using diet pills, or laxatives), and between BMI and suicidal ideation. It also explored the correlation between exposure to multiple UWCBs and suicidal ideation among Korean adolescents. Data on BMI, BWP, UWCBs, and suicidal ideation were obtained from the 2006 Korean Youth Risk Behavior Web-based Survey, a school-based survey conducted on a nationally representative sample of students in grades 7-12 (36,463 boys and 33,433 girls). Data were analyzed using bivariate and multivariate logistic regression. BMI was significantly associated with both UWCB and suicidal ideation among boys and girls, even after controlling for covariates. However, the significance and magnitude of the association between BMI and UWCB were considerably attenuated when BWP was added to the model. When BWP was included, the association between overweight BMI status and suicidal ideation became nonsignificant in both sexes, whereas the association between underweight BMI status and suicidal ideation remained significant among boys. Adolescent boys and girls engaging in multiple UWCBs were at greater risk for experiencing suicidal thoughts. This study suggests that BWP represents a potential mediator between BMI and UWCB, and between BMI and suicidal ideation among both boys and girls. Thus, school programs addressing issues related to BWP should be developed and targeted at adolescents to reduce the potential risks for both UWCB and suicidal behavior.

The aim of the present study was to assess the efficacy and safety of vildagliptin as add-on to sulfonylurea therapy in Chinese patients with type 2 diabetes mellitus (T2DM) inadequately controlled on sulfonylurea monotherapy. The 24-week randomized double-blind placebo-controlled study compared vildagliptin 50 mg, q.d., with placebo as add-on to glimepiride in T2DM patients who were inadequately controlled (HbA1c 7.5%-11.0% [58-97 mmol/mol]) on a stable dose of sulfonylurea for ≥12 weeks before study entry. In all, 279 patients were randomized to receive either vildagliptin (n = 143) or placebo (n = 136). At baseline, overall mean age was 58.5 years, body weight 68.1 kg, duration of diabetes 6.9 years and daily glimepiride dose 3.3 mg. After 24 weeks, the adjusted mean change (AMΔ) in HbA1c was -0.7% (-8 mmol/mol; baseline 8.6%, 70 mmol/mol) in the vildagliptin group and -0.2% (-2 mmol/mol; baseline 8.7%, 72 mmol/mol) in the placebo group, with a treatment difference of -0.5% (-5 mmol/mol; P < 0.001). The between-group difference in AMΔ in fasting plasma glucose was -0.4 mmol/L (P = 0.160). There was a slight, but not significant, decrease in body weight in both groups. No hypoglycemic events were reported in either group, including those patients reaching HbA1c <7.0%. Patients in the vildagliptin and placebo groups reported low and comparable incidences of adverse events (14.0% vs. 17.8%) and serious adverse events (0.7% in each group). Vildagliptin 50 mg, q.d., added to sulfonylurea monotherapy is effective in Chinese patients with T2DM, without increasing the risk of hypoglycemia and weight gain. © 2014 Ruijin Hospital, Shanghai Jiaotong University School of Medicine and Wiley Publishing Asia Pty Ltd.

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.

Extending Vulnerability Assessment to Include Life Stages Considerations

Species are experiencing a suite of novel stressors from anthropogenic activities that have impacts at multiple scales. Vulnerability assessment is one tool to evaluate the likely impacts that these stressors pose to species so that high-vulnerability cases can be identified and prioritized for monitoring, protection, or mitigation. Commonly used semi-quantitative methods lack a framework to explicitly account for differences in exposure to stressors and organism responses across life stages. Here we propose a modification to commonly used spatial vulnerability assessment methods that includes such an approach, using ocean acidification in the California Current as an illustrative case study. Life stage considerations were included by assessing vulnerability of each life stage to ocean acidification and were used to estimate population vulnerability in two ways. We set population vulnerability equal to: (1) the maximum stage vulnerability and (2) a weighted mean across all stages, with weights calculated using Lefkovitch matrix models. Vulnerability was found to vary across life stages for the six species explored in this case study: two krill–Euphausia pacifica and Thysanoessa spinifera, pteropod–Limacina helicina, pink shrimp–Pandalus jordani, Dungeness crab–Metacarcinus magister and Pacific hake–Merluccius productus. The maximum vulnerability estimates ranged from larval to subadult and adult stages with no consistent stage having maximum vulnerability across species. Similarly, integrated vulnerability metrics varied greatly across species. A comparison showed that some species had vulnerabilities that were similar between the two metrics, while other species’ vulnerabilities varied substantially between the two metrics. These differences primarily resulted from cases where the most vulnerable stage had a low relative weight. We compare these methods and explore circumstances where each method may be appropriate.

Weight gain and obesity are serious side effects of the medications used to manage psychotic disorders and successful, long-term weight loss interventions are not yet available. One reason for this may be that current interventions are designed without consideration of the patient's perspective. The purpose of this study was to explore the subjective experience of weight and lifestyle from the perspective of people with schizophrenia. A qualitative, constructivist research design was used and conversational interviews were conducted with 18 purposefully recruited participants from an outpatient clinic at a psychiatric hospital in Eastern Ontario. Data were analysed according to the method of constant comparison and three central themes emerged: a life altering diagnosis, weight management as complex, and today's experiences shape tomorrow's outcomes. Weight management was seen as difficult yet important to the participants. The findings of this study provide insight into the views and opinions of the participants regarding weight and lifestyle and may be used to support the design of tailored heath initiatives for persons with mental illness. © 2012 The Authors.

2015-11-01

In this work, the effect of poly(ethylene oxide) (PEO) molecular weight in blends of epoxy (ER) and PEO on the miscibility, inter-chain weak interactions and local dynamics were systematically investigated by multi-frequency temperature modulation DSC and solid-state NMR techniques. We found that the molecular weight (M(w)) of PEO was a crucial factor in controlling the miscibility, chain dynamics and hydrogen bonding interactions between PEO and ER. A critical PEO molecular weight (M(crit)) around 4.5k was found. PEO was well miscible with ER when the molecular weight was below M(crit), where the chain motion of PEO was restricted due to strong inter-chain hydrogen bonding interactions. However, for the blends with high molecular weight PEO (M(w) > M(crit)), the miscibility between PEO and ER was poor, and most of PEO chains were considerably mobile. Finally, polarization inversion spin exchange at magic angle (PISEMA) solid-state NMR experiment further revealed the different mobility of the PEO in ER/PEO blends with different molecular weight of PEO at molecular level. Based on the DSC and NMR results, a tentative model was proposed to illustrate the miscibility in ER/PEO blends.

Effects of vildagliptin as add-on treatment in patients with type 2 diabetes mellitus: insights from long-term clinical studies in Japan.

2015-01-01

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.

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.

Childhood obesity is a global health concern, but children with spina bifida in particular have unique interacting risk factors for increased weight. To identify and explore current clinical practices around weight assessment and management in pediatric spina bifida clinics. An online, self-report survey of healthcare professionals (HCPs) was conducted in all pediatric spina bifida clinics across Canada (15 clinics). Summary and descriptive statistics were calculated and descriptive thematic analysis was performed on free text responses. 52 responses across all 15 clinics indicated that weight and height were assessed and recorded most of the time using a wide variety of methods, although some HCPs questioned their suitability for children with spina bifida. Weight and height information was not routinely communicated to patients and their families and HCPS identified considerable barriers to discussing weight-related information in consultations. Despite weight and height reportedly being measured regularly, HCPs expressed concern over the lack of appropriate assessment and classification tools. Communication across multi-disciplinary team members is required to ensure that children with weight-related issues do not inadvertently get overlooked. Specific skill training around weight-related issues and optimizing consultation time should be explored further for HCPs working with this population.

To compare the efficacy and safety of adding liraglutide, saxagliptin and vildagliptin to current therapy in Chinese type 2 diabetes subjects with poor glycemic control.A 24-week, randomized, open-label, parallel clinical trial was performed. A total 178 patients completed the trial who had been randomly assigned to add-on once daily liraglutide (1.2 mg/day injected subcutaneously), to saxagliptin (5 mg once daily) or to vildagliptin (50 mg twice daily). Glycosylated hemoglobin (HbA1c) values, fasting and postprandial blood glucose (FBG and P2BG), body weight, body mass index (BMI), episodes of hypoglycemia and adverse events were evaluated.Over the 24-week treatment period, greater lowering of mean of HbA1c was achieved with 1.2 mg liraglutide (-1.50%, 95% CI [-1.67, -1.34]) than with saxagliptin (-1.23%, 95% CI [-1.36, -1.11]) and vildagliptin (-1.25%, 95% CI [-1.37, -1.13]). There was no significant between-group difference of percentages of subjects who reached a target HbA1c<7.0%, but significantly more subjects with liraglutide achieved HbA1c≤6.5% compared with saxagliptin and vildagliptin. The mean reduction of FBG value from baseline was 2.23 mmol/L with liraglutide, much greater than 1.83 mmol/L with saxagliptin (p=0.013), but similar to 2.03 mmol/L with -vildaglitpin group. As to the P2BG value, greater reductions was found with liraglutide (-4.80 mmol/L) than -3.56 mmol/L with saxagliptin (p=0.000) and -3.57 mmol/L with vildagliptin (p=0.000). Moreover, greater mean reductions of body weight and BMI with liraglutide (-6.0 kg and -2.1 kg/m(2)) were achieved than with saxagliptin and vildagliptin (both p<0.001), whereas no significant difference was found between saxagliptin and vildagliptin group. The incidence of hypoglycemia was recorded low and similar in each treatment group. Nausea was more common with liraglutide (27%) than with saxagliptin (3.2%) and vildagliptin (5.2%), but no significant between-group difference was reported

Prokinetics for functional dyspepsia (FD) have relatively higher number needed to treat values. Acupuncture and related therapies could be used as add-on or alternative. An overview of systematic reviews (SRs) and network meta-analyses (NMA) were performed to evaluate the comparative effectiveness of different acupuncture and related therapies. We conducted a comprehensive literature search for SRs of randomized controlled trials (RCTs) in eight international and Chinese databases. Data from eligible RCTs were extracted for random effect pairwise meta-analyses. NMA was used to explore the most effective treatment among acupuncture and related therapies used alone or as add-on to prokinetics, compared to prokinetics alone. From five SRs, 22 RCTs assessing various acupuncture and related therapies were included. No serious adverse events were reported. Two pairwise meta-analyses showed manual acupuncture has marginally stronger effect in alleviating global FD symptoms, compared to domperidone or itopride. Results from NMA showed combination of manual acupuncture and clebopride has the highest probability in alleviating patient reported global FD symptom. Combination of manual acupuncture and clebopride has the highest probability of being the most effective treatment for FD symptoms. Patients who are contraindicated for prokinetics may use manual acupuncture or moxibustion as alternative. Future confirmatory comparative effectiveness trials should compare clebopride add-on manual acupuncture with domperidone add-on manual acupuncture and moxibustion.

Objective The National Weight Control Registry (NWCR) was established in 1993 to examine the characteristics of those who are successful at weight loss: individuals maintaining a 13.6-kg weight loss for >1 year. The size of the registry has increased substantially since the early descriptions of this group a decade ago. The purpose of this study was to describe in detail the weekly physical activity habits of NWCR members, to examine the relationship between amount of activity and demographic characteristics, and to determine if changes in activity parameters have occurred over time. Methods and Procedures Participants were 887 men and 2,796 women who enrolled in the NWCR between 1993 and 2004. Physical activity was evaluated at registry entry using the Paffenbarger Physical Activity Questionnaire. Results NWCR entrants report an average of 2,621 ± 2,252 kcal/week in physical activity. There is considerable variability in the amount of activity reported: 25.3% report <1,000 kcal/week and 34.9% report >3,000 kcal/week. Activity level on registry entry is related to the magnitude but not the duration of weight loss. The amount of activity reported by men has decreased over time while no significant change was observed in women. Changes in the types of activities most frequently reported were also observed. Discussion Overall, NWCR participants are an extremely physically active group. However, the amount of activity reported is highly variable, making it difficult to develop a single recommendation for the optimum amount of physical activity for weight loss maintenance. A better understanding of individual-specific determinants of how much activity is required for weight loss maintenance ought to be a high research priority. PMID:18223628

Body composition changes after weight-loss interventions for overweight and obesity.

Santarpia, Lidia; Contaldo, Franco; Pasanisi, Fabrizio

2013-04-01

Weight-loss interventions to correct overweight and obesity are very popular but often inappropriate and unsuccessful. In this review we evaluated studies on body composition changes during and after different medical and surgical interventions aimed at achieving stable weight loss in overweight and obese individuals. Most of the available literature and good clinical practice observations deal mainly with post-menopausal overweight and obese women, and, to a lesser extent adolescents and elderly, female and male, populations. These studies suggest that weight-loss maintenance interventions should have greater consideration and priority than simple weight-loss treatments. At a long term follow up (over one year), relatively high protein, moderately low calorie, low glycemic index diets, associated with a daily, moderate intensity, physical exercise (of at least 30 min), appear to be more successful in limiting long term relapse, maintaining fat free mass and achieving the highest fat loss. Diet alone or physical exercise alone does not produce similar results. Health professional training and practice also appear a challenging target. Adequate dietetic advice plus regular physical exercise avoid the fat-free-mass loss usually observed in the relapse of the weight cycling syndrome and prevent the onset of sarcopenic obesity.

Adolescent smoking, weight changes, and binge-purge behavior: associations with secondary amenorrhea.

PubMed

Johnson, J; Whitaker, A H

1992-01-01

The association of secondary amenorrhea with extreme forms of substance use, weight control, and exercise in nonrepresentative samples raises questions as to whether adolescents in the general population who engage in these behaviors are at increased risk for secondary amenorrhea. We examined the prevalence and behavioral correlates of secondary amenorrhea in a county-wide high school population of 2544 girls aged 13 to 18. A survey questionnaire, which elicited menstrual history as well as weight history, weight control practices, level of exercise, and use of cigarettes, wine, and beer, was administered during school hours; absentees were also surveyed. The completion rate was 91%. The 1-year prevalence of secondary amenorrhea was 8.5%. Secondary amenorrhea was associated with smoking one or more packs of cigarettes per day (adjusted relative risk [RRa] = 1.96, 1.21-3.10), with multiple binge-eating behaviors in combination with laxative use or self-induced vomiting (RRa = 4.17, 2.54-6.32), and with weight fluctuation due to weight control (RRa = 2.59, 1.33-4.79). There was no association between amenorrhea and alcohol consumption or exercise level. Estimates of attributable risk are provided and indicate that bulimic behaviors and cigarette smoking may result in a considerable excess of cases of secondary amenorrhea in an adolescent population.

Childhood obesity is a serious problem in the UK, with around 20% of children aged 10-11 being overweight or obese. Lifestyle interventions can be effective, but there is limited evidence of their effectiveness in delivering sustained weight loss. The present research explored potential of web-based, 3-dimensional virtual worlds (VWs) for facilitation of weight-management, well-being and patient and public involvement (PPI) for young people. Attendees of a weight management camp took part in induction sessions for use of the VW of Second Life. All participants successfully learned how to interact with one another and navigate the virtual environment. Participant appraisals of Second Life were varied. Some found it complicated and difficult to use, and some found it fun and the majority stated that they would choose to use VWs again. There is considerable potential for use of VWs to promote weight management, and Second Life or a similar VW could be used to deliver this. Potential barriers include members of the target sample having limited access to computers with necessary system requirements for running VWs, and that some may find VW-based educational experiences unappealing or challenging to navigate. For some however, VWs may provide a useful mode for provision of education, PPI and support relating to weight management. PMID:27540446

Background Treatment decisions for older patients with type 2 diabetes mellitus must balance glycemic control and adverse event risk. The objective of this study was to evaluate the long-term safety and tolerability of saxagliptin 5 mg as add-on therapy to common antihyperglycemic drugs in patients aged ≥65 years and <65 years. Methods Pooled adverse event data from three placebo-controlled trials of 76–206 weeks’ duration in older (≥65 years) and younger (<65 years) patients receiving saxagliptin 5 mg or matching placebo added to metformin, glyburide, or a thiazolidinedione were analyzed. Measurements were calculated from day of first dose to specified event or last dose and included time at risk for adverse events, treatment-related adverse events, serious adverse events, adverse events leading to discontinuation, and events of special interest. Weighted incidence rates (number of events/total time) and incidence rate ratios (saxagliptin/placebo) with 95% confidence intervals were calculated (Mantel-Haenszel test). Results A total of 205 older (mean age 69 years; saxagliptin, n=99; placebo, n=106) and 1,055 younger (mean age 52 years; saxagliptin, n=531; placebo, n=524) patients were assessed. Regardless of age category, the adverse event incidence rates were generally similar between treatments, with confidence intervals for incidence rate ratios bridging 1. Treatment-related adverse events occurred in 36 older patients receiving saxagliptin versus 32 receiving placebo (incidence rate 34.1 versus 27.1 per 100 person-years) and in 150 younger patients in both treatment groups (incidence rate 24.0 versus 27.8 per 100 person-years). With saxagliptin versus placebo, serious adverse events occurred in eight versus 14 older (incidence rate 5.7 versus 9.9 per 100 person-years) and 49 versus 44 younger patients (incidence rate 6.5 versus 6.6 per 100 person-years). There were two deaths (one patient ≥65 years) with saxagliptin and six (none aged ≥65 years

Low molecular weight phenols of Tannat red wines produced by Traditional Maceration (TM), Prefermentative Cold Maceration (PCM), Maceration Enzyme (ENZ) and grape-Seed Tannins additions (ST), were performed and discussed. Alternatives to TM increased wine phenolic contents but unequally, ST increased mainly smaller flavans-3-ol, PCM anthocyanins and ENZ proanthocyanidins (up to 2250 mg/L). However low molecular weight flavan-3-ols remained below 9 mg/L in all wines, showing that there is not necessarily a correspondence between wine richness in total tannins and flavan-3-ols contents at low molecular weight. PCM wines had particularly high concentrations of tyrosol and tryptophol, yeast metabolism derived compounds. The use of grape-seed enological tannins did not increase grape seed derived phenolic compounds such as gallic acid. Caftaric acid was found in concentrations much higher than those reported in other grape varieties. Wine phenolic content and composition was considerably affected by the winemaking procedures tested. Copyright © 2014 Elsevier Ltd. All rights reserved.

Consideration of the ICRP 2006 revised tissue weighting factors on age-dependent values of the effective dose for external photons

The effective dose recommended by the International Commission on Radiological Protection (ICRP) is the sum of organ equivalent doses weighted by corresponding tissue weighting factors, wT. ICRP is in the process of revising its 1990 recommendations on the effective dose where new values of organs and tissue weighting factors have been proposed and published in draft form for consultation by the radiological protection community. In its 5 June 2006 draft recommendations, new organs and tissues have been introduced in the effective dose which do not exist within the 1987 Oak Ridge National Laboratory (ORNL) phantom series (e.g., salivary glands). Recently, the investigators at University of Florida have updated the series of ORNL phantoms by implementing new organ models and adopting organ-specific elemental composition and densities. In this study, the effective dose changes caused by the transition from the current recommendation of ICRP Publication 60 to the 2006 draft recommendations were investigated for external photon irradiation across the range of ICRP reference ages (newborn, 1-year, 5-year, 10-year, 15-year and adult) and for six idealized irradiation geometries: anterior-posterior (AP), posterior-anterior (PA), left-lateral (LLAT), right-lateral (RLAT), rotational (ROT) and isotropic (ISO). Organ-absorbed doses were calculated by implementing the revised ORNL phantoms in the Monte Carlo radiation transport code, MCNPX2.5, after which effective doses were calculated under the 1990 and draft 2006 evaluation schemes of the ICRP. Effective doses calculated under the 2006 draft scheme were slightly higher than estimated under ICRP Publication 60 methods for all irradiation geometries exclusive of the AP geometry where an opposite trend was observed. The effective doses of the adult phantom were more greatly affected by the change in tissue weighting factors than that seen within the paediatric members of the phantom series. Additionally, dose conversion

Introduction The high prevalence of overweight and obesity threatens the health and safety of the fire service. Healthcare professionals may play an important role in helping firefighters achieve a healthy weight by providing weight loss counseling to at-risk firefighters. This study characterizes the impact of healthcare professional weight loss advice on firefighter weight perceptions and weight loss behaviors among overweight and obese male firefighters. Methods A national sample of 763 overweight and obese male firefighters who recalled visiting a healthcare provider in the past 12 months reported information regarding healthcare visits, weight perceptions, current weight loss behaviors, and other covariates in 2011–2012. Analyzed in 2013, four unique multilevel logistic regression models estimated the association between healthcare professional weight loss advice and the outcomes of firefighter-reported weight perceptions, intentions to lose weight, reduced caloric intake, and increased physical activity. Results Healthcare professional weight loss advice was significantly associated with self-perception as overweight (OR=4.78, 95% CI=2.16, 10.57) and attempted weight loss (OR=2.06, 95% CI=1.25, 3.38), but not significantly associated with reduced caloric intake (OR=1.26, 95% CI=0.82, 1.95) and increased physical activity (OR=1.51, 95% CI=0.89, 2.61), after adjusting for confounders. Conclusions Healthcare professional weight loss advice appears to increase the accuracy of firefighter weight perceptions, promote weight loss attempts, and may encourage dieting and physical activity behaviors among overweight firefighters. Healthcare providers should acknowledge their ability to influence the health behaviors of overweight and obese patients and make efforts to increase the quality and frequency of weight loss recommendations for all firefighters.

This paper explores the cause of confusion associated with the words mass and weight, and offers suggestions to correct the problem. It is recommended that in technical and scientific use, weight shall be restricted to mean force of gravity. Technical standards, ASTM and others, and terminology shall clearly reflect and define weight to be force of gravity. Weight should be avoided in technical context because of its imprecision. Legal, formal, and official language shall use weight to mean force only. Under no circumstances should the SI units of mass, the kilogram, or its derivatives, be associated with weight. The termmore » weight should be avoided in any language and wording that intends to convey a precise or important meaning. ASTM should revise all standards and terminology accordingly.« less

Molecular physiology of weight regulation in mice and humans

PubMed Central

Leibel, RL

2009-01-01

Evolutionary considerations relating to efficiency in reproduction, and survival in hostile environments, suggest that body energy stores are sensed and actively regulated, with stronger physiological and behavioral responses to loss than gain of stored energy. Many physiological studies support this inference, and suggest that a critical axis runs between body fat and the hypothalamus. The molecular cloning of leptin and its receptor—projects based explicitly on the search for elements in this axis—confirmed the existence of this axis and provided important tools with which to understand its molecular physiology. Demonstration of the importance of this soma-brain reciprocal connection in body weight regulation in humans has been pursued using both classical genetic approaches and studies of physiological responses to experimental weight perturbation. This paper reviews the history of the rationale and methodology of the cloning of leptin (Lep) and the leptin receptor (Lepr), and describes some of the clinical investigation characterizing this axis.

How PET/MR Can Add Value For Children With Cancer.

PubMed

Daldrup-Link, Heike

2017-03-01

To review how PET/MR technology could add value for pediatric cancer patients. Since many primary tumors in children are evaluated with MRI and metastases are detected with PET/CT, integrated PET/MR can be a time-efficient and convenient solution for pediatric cancer staging. 18 F-FDG PET/MR can assess primary tumors and the whole body in one imaging session, avoid repetitive anesthesia and reduce radiation exposure compared to 18 F-FDG PET/CT. This article lists 10 action points, which might improve the clinical value of PET/MR for children with cancer. However, even if PET/MR proves valuable, it cannot enter mainstream applications if it is not accessible to the majority of pediatric cancer patients. Therefore, innovations are needed to make PET/MR scanners affordable and increase patient throughput. PET/MR offers opportunities for more efficient, accurate and safe diagnoses of pediatric cancer patients. The impact on patient management and outcomes has to be substantiated by large-scale prospective clinical trials.

Bidirectional association between weight status and motor skills in adolescents : A 4-year longitudinal study.

Despite considerable efforts the prevalence of overweight and obesity in youth remains high. Poor motor skills have been associated with increased body weight but there is still limited information on the longitudinal association of these health parameters. This study examined the prospective association between motor skills and body weight in 10- to 14-year-old youth. Body weight, height and motor skills, assessed via the German motor test 16-18 (Deutscher Motorik Test, DMT6-18), were measured in 213 middle school students (57% male) every year over a 4‑year period. Club sports participation and migration status were assessed via a questionnaire. Besides an inverse cross-sectional association between body weight and motor skills, excess body weight was associated with impaired development of motor skills (p < 0.05). Furthermore, weight loss was associated with enhanced motor development and allowed previously overweight students to catch up with their normal weight peers. High motor skills at baseline also reduced the odds of becoming overweight/obese during the observation period. These results were independent of club sports participation. There is a bidirectional, synergistic association between body weight and motor skills. Facilitating the development of motor skills in children and adolescents may therefore be a viable intervention strategy targeting weight management and physical activity in youth.

The COMT Val158Met Polymorphism Is Associated With Response to Add-on Dextromethorphan Treatment in Bipolar Disorder.

We previously conducted a randomized, double-blind, controlled, 12-week study evaluating the effect of add-on dextromethorphan (DM), a noncompetitive N-methyl-D-aspartate receptor antagonist, on patients with bipolar disorder (BD) treated using valproate (VPA), which showed negative clinical differences. The genetic variation between each individual may be responsible for interindividual differences. The catechol-O-methyltransferase (COMT) gene has been a candidate gene for BD. In the current study, we investigated whether the COMT Val158Met polymorphism predicts treatment response to VPA + add-on DM and to VPA + placebo. Patients with BD (n = 309) undergoing regular VPA treatments were randomly assigned to groups given either add-on DM (30 mg/d) (n = 102), DM (60 mg/d) (n = 101), or placebo (n = 106) for 12 weeks. The Hamilton Depression Rating Scale and Young Mania Rating Scale were used to evaluate clinical response during weeks 0, 1, 2, 4, 8, and 12. The genotypes of the COMT Val158Met polymorphism were determined using polymerase chain reaction plus restriction fragment length polymorphism analysis. To adjust for within-subject dependence over repeated assessments, multiple linear regression with generalized estimating equation methods was used. When stratified by the COMT Val158Met genotypes, significantly greater decreases in Hamilton Depression Rating Scale scores were found in the VPA + DM (30 mg/d) group in patients with the Val/Met genotype (P = 0.008). We conclude that the COMT Val158Met polymorphism may influence responses to DM (30 mg/d) by decreasing depressive symptoms in BD patients.

Bipolar disorder (BD), especially BD-II, is frequently comorbid with alcohol dependence. Because BD-II and alcohol dependence are neurodegenerative disorders, agents with anti-inflammatory and neurotrophic effects might provide effective therapy. We investigated whether add-on memantine to regular valproic acid treatment ameliorated clinical symptoms, reduced alcohol use, and cytokine levels, and increased plasma brain-derived neurotrophic factor (BDNF) in BD-II patients with comorbid alcohol dependence. In a single-arm 12-week clinical trial, BD-II patients with comorbid alcohol dependence (n = 45) undergoing regular valproic acid treatments were given add-on memantine (5 mg/d). Symptom severity, alcohol use, cytokine (plasma tumor necrosis factor-α and C-reactive protein [CRP], transforming growth factor-β1 [TGF-β1], interleukin-8 [IL-8], IL-10), and plasma BDNF levels were regularly assessed. Mean within-group decreases in Hamilton Depression Rating Scale (HDRS) and Young Mania Rating Scale (YMRS) scores, alcohol use, CRP, BDNF, and IL-8 levels were significantly different from baseline after 12 weeks of treatment. We found no significant correlation between alcohol use levels and changes in HDRS or YMRS scores. The correlation between reduced alcohol use and reduced TGF-β1 level was significant (B = 0.003, p = 0.019). BD-II comorbid with alcohol dependence might benefit from add-on memantine treatment, which significantly reduced clinical severity, alcohol use, and plasma cytokine levels, and increased BDNF levels.

As shown by a simple model of the flow of STS equipment through ground processing and flights under ideal conditions, mission duration is constrained by Orbiter availability, which is determined initially by the Orbiter production schedule and the turnaround time required between missions, and by the usage rate and quantity limitations of mission consumables. Additional considerations affecting mission duration include reductions in crew productivity upon increased mission duration and crew size, spacecraft and experiment degradation, equipment and processing facility cost effectiveness, and requirements for a power extension package, which considerations imply that increased allowable landing weight would make co-manifesting (the combination of Spacelab and deliverable payload missions) more attractive. Advantages related to payload recoverability, human presence, ease of access and the availability of different orbits are also pointed out.

The high prevalence of overweight and obesity threatens the health and safety of the fire service. Healthcare professionals may play an important role in helping firefighters achieve a healthy weight by providing weight loss counseling to at-risk firefighters. This study characterizes the impact of healthcare professional weight loss advice on firefighter weight perceptions and weight loss behaviors among overweight and obese male firefighters. A national sample of 763 overweight and obese male firefighters who recalled visiting a healthcare provider in the past 12 months reported information regarding healthcare visits, weight perceptions, current weight loss behaviors, and other covariates in 2011-2012. Analyzed in 2013, four unique multilevel logistic regression models estimated the association between healthcare professional weight loss advice and the outcomes of firefighter-reported weight perceptions, intentions to lose weight, reduced caloric intake, and increased physical activity. Healthcare professional weight loss advice was significantly associated with self-perception as overweight (OR=4.78, 95% CI=2.16, 10.57) and attempted weight loss (OR=2.06, 95% CI=1.25, 3.38), but not significantly associated with reduced caloric intake (OR=1.26, 95% CI=0.82, 1.95) and increased physical activity (OR=1.51, 95% CI=0.89, 2.61), after adjusting for confounders. Healthcare professional weight loss advice appears to increase the accuracy of firefighter weight perceptions, promote weight loss attempts, and may encourage dieting and physical activity behaviors among overweight firefighters. Healthcare providers should acknowledge their ability to influence the health behaviors of overweight and obese patients and make efforts to increase the quality and frequency of weight loss recommendations for all firefighters.
