    Full Text Available Electronic commerce has experienced rapid growth in last years. B2C electronic commerce often has a high customer loss rate. To regain the lost customers is a major concern of online vendors. This paper investigates the strategies for winning back lost customers (price promotion and relationship investment through field experiment on a major B2C website in China. Research findings indicate the two strategies are effective in regaining lost customers online, depending on the customers’ prior relationship time with the vendor, and lapse time from the vendor. The study has contribution to electronic commerce and has practical implications for B2C vendors on customer management.

    We recently reported a previously unidentified strategy of self-repair in the moon jellyfish Aurelia aurita. Rather than regenerating lost parts, juvenile Aurelia reorganize remaining parts to regain essential body symmetry. This process that we called symmetrization is rapid and frequent, and is not driven by cell proliferation or cell death. Instead, the swimming machinery generates mechanical forces that drive symmetrization. We found evidence for symmetrization across three other species of jellyfish (Chrysaora pacifica, Mastigias sp., and Cotylorhiza tuberculata). We propose reorganization to regain function without recovery of initial morphology as a potentially broad class of self-repair strategy beyond radially symmetrical animals, and discuss the implications of this finding on the evolution of self-repair strategies in animals.

    Transmission spectroscopy facilitates the detection of molecules and/or clouds in the atmospheres of exoplanets. Such studies rely heavily on space-based or large ground-based observatories, as one needs to perform time- resolved, high signal-to-noise spectroscopy. The FORS2 instrument at ESO's Very Large Telescope is the obvious choice for performing such studies, and was indeed pioneering the field in 2010. After that, however, it was shown to suffer from systematic errors caused by the Longitudinal Atmospheric Dispersion Corrector (LADC). This was successfully addressed, leading to a renewed interest for this instrument as shown by the number of proposals submitted to perform transmission spectroscopy of exoplanets. We present here the context, the problem and how we solved it, as well as the recent results obtained. We finish by providing tips for an optimum strategy to do transmission spectroscopy with FORS2, in the hope that FORS2 may become the instrument of choice for ground-based transmission spectro...

    2013-01-01

    Full Text Available Achieving optimal weight outcomes for patients with obesity is important to the management of their chronic disease. All interventions present risks for weight regain. Bariatric surgery is the most efficacious treatment, producing greater weight losses that are sustained over more time compared to lifestyle interventions. However, approximately 20–30% of patients do not achieve successful weight outcomes, and patients may experience a regain of 20–25% of their lost weight. This paper reviews several factors that influence weight regain after bariatric surgery, including type of surgery, food tolerance, energy requirements, drivers to eat, errors in estimating intake, adherence, food and beverage choices, and patient knowledge. A comprehensive multidisciplinary approach can provide the best care for patients with weight regain. Nutrition care by a registered dietitian is recommended for all bariatric surgery patients. Nutrition diagnoses and interventions are discussed. Regular monitoring of weight status and early intervention may help prevent significant weight regain.

  10. Regaining Weaver and Shannon

    Full Text Available My claim is that communication considered from the standpoint of how it is modeled must not only reckon with Claude E. Shannon and Warren Weaver but regain their pioneering efforts in new ways. I want to regain two neglected features. I signal these ends by simply reversing the order in which their names commonly appear.First, the recontextualization of Shannon and Weaver requires an investigation of the technocultural scene of information ‘handling’ embedded in their groundbreaking postwar labours; not incidentally, it was Harold D. Lasswell, whose work in the 1940s is often linked with Shannon and Weaver’s, who made a point of distinguishing between those who affect the content of messages (controllers as opposed to those who handle without modifying (other than accidentally such messages. Although it will not be possible to maintain such a hard and fast distinction that ignores scenes of encoding and decoding, Lasswell’s (1964: 42-3 examples of handlers include key figures such as ‘dispatchers, linemen, and messengers connected with telegraphic communication’ whose activities will prove to be important for my reading of the Shannon and Weaver essays. Telegraphy and its occupational cultures are the technosocial scenes informing the Shannon and Weaver model.Second, I will pay special attention to Weaver’s contribution, despite a tendency to erase him altogether by means of a general scientific habit of listing the main author first and then attributing authorship only to the first name on the list (although this differs within scientific disciplines, particularly in the health field where the name of the last author is in the lead, so to speak. I begin with a displacement of hierarchy and authority. I am inclined to simply state for those who, in the manner of Sherlock Holmes, ‘know my method’, that I focus my attention on the less well-known half of thinking pairs – on Roger Caillois instead of Georges Bataille, on F

  12. Life behind cell walls: paradigm lost, paradigm regained.

    Lamport, D T

    2001-09-01

    This review of the living cell wall and its protein components is in two parts. The first is anecdotal. A personal account spanning over 40 years research may perhaps be an antidote to one stereotypical view of scientists as detached and humorless. The second part deals with the meaning of function, particularly as it applies to hydroxyproline-rich glycoproteins. Function is a difficult word to define objectively. However, with help from such luminaries as Humpty Dumpty: "A word means what I want it to mean, neither more nor less," and Wittgenstein: "Giving examples of usage ... is the only way to talk about meaning," it is possible to construct a ziggurat representing increasingly complex levels of organization from molecular structure to ecology. Forty years ago I suggested that hydroxyproline-rich structural proteins played a key role in cell wall functioning. But because the bulk of the wall is carbohydrate, there has been an understandable resistance to paradigm change. Expansins, paradoxically, contribute greatly to this resistance because their modus operandi as cell-wall-loosening proteins is based on the idea that they break hydrogen bonds between polysaccharide chains allowing slippage. However, this view is not consistent with the recent discovery [Grobe et al. (1999) Eur. J. Biochem 263: 33-40] that beta-expansins may be proteases, as it implies that the extensin network is not a straightjacket but a substrate for expansin in muro. Such a direct role for extensins in both negative and positive regulation of cell expansion and elongation may constitute a major morphogenetic mechanism operating at all levels of plant growth and development.

    Dietary restriction interventions are effective for weight loss and reduction of chronic disease risk. Unfortunately, most people tend to regain much of this lost weight within one year after intervention. While some studies suggest that minor degrees of weight regain have no effect on metabolic disease risk parameters, other studies demonstrate a complete reversal in metabolic benefits. In light of these conflicting findings, it is of interest to determine how complete weight maintenance versus mild weight regain affects key risk parameters. These findings would have important clinical implications, as they could help identify a weight regain threshold that could preserve the metabolic benefits of weight loss. Accordingly, this review examined the impact of no weight regain versus mild regain on various metabolic disease risk parameters, including plasma lipids, blood pressure, glucose, and insulin concentrations, in adult subjects.

    2017-01-01

    Full Text Available In Lost Ground, Michiel Heyns portrays the former white settlers’ position and experience in South Africa, Africa and Europe after the overturn of South Africa’s apartheid regime. An analysis of the novel illustrates that the legacy of the colonisation of Africa and apartheid in South Africa still shapes the settler descendants’ perception of self and the other and the formers’ place in South Africa and Africa. After the electoral victory of the African National Congress, contemporary white South African men, as exemplified by the English-speaking male protagonist who features in the novel, tend to dissociate themselves from the country and the African continent as home. Although the original colonisers’ experience of alienation and ambivalence about apartheid has been widely depicted, the significance of this experience in relation to white South African male identity has not been fully explored in a study of Heyns’s Lost Ground, principally as regards the novel’s detective narrative framework and the counterdiscursive technique of intertextual referencing that implies other interpretative possibilities. Lost Ground will be critically analysed in terms of the central character’s experience of space and place, and the influence of these paradigms on Peter Jacobs as he makes strides towards abandoning historical/racial restrictions and locating his identity in people.

    Weight-classified athletes need an energy intake plan to accomplish target weight reduction. They have to consider body composition and energy metabolism during rapid weight loss followed by rapid weight regain to achieve their energy intake plan. We investigated the effects of rapid weight loss, followed by weight regain, on body composition and energy expenditure. Ten weight-classified athletes were instructed to reduce their body weight by 5% in 7 days. Following the weight loss, they were asked to try to regain all of their lost weight with an ad libitum diet for 12 h. Food intake was recorded during the baseline, weight loss, and regain periods. Fat mass, total body water, and fat-free dry solids were estimated by underwater weighing and stable isotope dilution methods. A three-component model was calculated using Siri's equation. Basal and sleeping metabolic rates were measured by indirect calorimetry. Body composition and energy expenditure were measured before and after weight loss and after weight regain. Body weight, total body water, and fat-free dry solids were decreased after the weight loss period but recovered after weight regain (p weight loss but recovered after weight regain. Changes in total body water greatly affect body weight during rapid weight loss and regain. In addition, rapid weight loss and regain did not greatly affect the basal metabolic rate in weight-classified athletes.

    A subset of bariatric patients fails to achieve or maintain long-term successful weight loss. Psychological and behavioral factors contributing to poor long-term outcomes include decreased adherence to surgical eating guidelines, life stressors that derail weight maintenance, unhealthy eating patterns, and substance use. A 6-week pilot group behavioral intervention utilizing techniques of cognitive behavioral therapy (CBT) and dialectical behavior therapy (DBT) was developed to treat bariatric patients experiencing weight regain. Patients were treated at a large Midwestern academic medical center. Twenty-eight patients (93% female, 100% Caucasian) with a mean age of 53 and a mean BMI of 35.6 had regained an average of 17 kg or 37% of the weight lost after initially successful Roux-en-Y gastric bypass (RYGB). All patients completed the Structured Clinical Interview for DSM-IV-TR (SCID I) modules assessing mood and substance dependence, and completed a series of questionnaires before and after group treatment, with weekly assessment of depressive symptoms, binge eating, and alcohol use. Results were analyzed utilizing repeated measures ANOVA. Weight decreased during the intervention by an average of 1.6 ± 2.38 kg (p ≤ 0.01). Level of depressive symptoms improved for treatment completers (p ≤ 0.01). Food records indicated that grazing patterns decreased (p ≤ 0.01) and subjective binge eating episodes decreased (p ≤ 0.03). A 6-week pilot group behavioral intervention demonstrated an ability to help patients reverse their pattern of weight regain. Tailored behavioral interventions may be a useful treatment to enhance maintenance of long-term weight loss.

    The Lost Creek Designated Ground Water Basin (Lost Creek basin) is an important alluvial aquifer for irrigation, public supply, and domestic water uses in northeastern Colorado. Beginning in 2005, the U.S. Geological Survey, in cooperation with the Lost Creek Ground Water Management District and the Colorado Water Conservation Board, collected hydrologic data and constructed a steady-state numerical groundwater flow model of the Lost Creek basin. The model builds upon the work of previous investigators to provide an updated tool for simulating the potential effects of various hydrologic stresses on groundwater flow and evaluating possible aquifer-management strategies. As part of model development, the thickness and extent of regolith sediments in the basin were mapped, and data were collected concerning aquifer recharge beneath native grassland, nonirrigated agricultural fields, irrigated agricultural fields, and ephemeral stream channels. The thickness and extent of regolith in the Lost Creek basin indicate the presence of a 2- to 7-mile-wide buried paleovalley that extends along the Lost Creek basin from south to north, where it joins the alluvial valley of the South Platte River valley. Regolith that fills the paleovalley is as much as about 190 ft thick. Average annual recharge from infiltration of precipitation on native grassland and nonirrigated agricultural fields was estimated by using the chloride mass-balance method to range from 0.1 to 0.6 inch, which represents about 1-4 percent of long-term average precipitation. Average annual recharge from infiltration of ephemeral streamflow was estimated by using apparent downward velocities of chloride peaks to range from 5.7 to 8.2 inches. Average annual recharge beneath irrigated agricultural fields was estimated by using passive-wick lysimeters and a water-balance approach to range from 0 to 11.3 inches, depending on irrigation method, soil type, crop type, and the net quantity of irrigation water applied

    Objectives We sought to determine: 1) if early weight regain between one and two years after RYGB is associated with worsened hepatic and peripheral insulin sensitivity, and 2) if preoperative levels of ghrelin and leptin are associated with early weight regain after RYGB. Design and Methods Hepatic and peripheral insulin sensitivity and ghrelin and leptin plasma levels were assessed longitudinally in 45 subjects before RYGB and at one month, six months, one year, and two years post operatively. Weight regain was defined as ≥ 5% increase in body weight between one and two years after RYGB. Results Weight regain occurred in 33% of subjects, with an average increase in body weight of 10 ± 5 % (8.5 ± 3.3 kg). Weight regain was not associated with worsening of peripheral or hepatic insulin sensitivity. Subjects with weight regain after RYGB had higher preoperative and postoperative levels of ghrelin compared to those who maintained or lost weight during this time. Conversely, the trajectories of leptin levels corresponded with the trajectories of fat mass in both groups. Conclusions Early weight regain after RYGB is not associated with a reversal of improvements in insulin sensitivity. Higher preoperative ghrelin levels might identify patients that are more susceptible to weight regain after RYGB. PMID:24777992

    Bariatric surgery leads to an average loss of 60-75% of excess body weight with maximum weight loss in the period between 18 and 24 months postoperatively. However, several studies show that weight is regained from two years of operation. To identify the determinants of weight regain in post-bariatric surgery users. Prospective cross-sectional study with 64 patients who underwent bariatric surgery with postoperative time > 2 years valued at significant weight regain. The variables analyzed were age, sex, education, socioeconomic status, work activity related to food, time after surgery, BMI, percentage of excess weight loss, weight gain, attendance monitoring nutrition, lifestyle, eating habits, self-perception of appetite, daily use of nutritional supplements and quality of life. There were 57 (89%) women and 7 (11%) men, aged 41.76 ± 7.93 years and mean postoperative period of 53.4 ± 18.4 months. The average weight and BMI were respectively 127.48 ± 24.2 kg and 49.56 ± 6.7 kg/m2 at surgery. The minimum weight and BMI were achieved 73.0 ± 18.6 kg and 28.3 ± 5.5 kg/m2, reached in 23.7 ± 12 months postoperatively. Regained significant weight occurred in 18 (28.1%) cases. The mean postoperative period of 66 ± 8.3 months and work activities related to food showed statistical significance (p=000 and p=0.003) for the regained weight. Bariatric surgery promotes adequate reduction of excess body weight, with significant weight regain observed after five years; post-operative time and work activity related to eating out as determining factors for the occurrence of weight regain.

    Specific methylation of appetite-related genes in leukocytes could serve as a useful biomarker to predict weight regain after an energy restriction program. We aimed to evaluate whether the pre-intervention DNA methylation patterns involved in the epigenetic control of appetite-regulatory genes in leukocytes are associated with the weight regain process. Eighteen men who lost ≥5% of body weight after an 8-week nutritional intervention were categorized as "regainers" (≥10% weight regain) and "non-regainers" (weight regain) 32weeks after stopping dieting. At baseline, leukocytes were isolated and DNA was analyzed for epigenetic methylation patterns of appetite-related gene promoters by MALDI-TOF mass spectrometry. Regainers showed higher methylation levels than non-regainers in proopiomelanocortin (POMC) CpG sites +136bp and +138bp (fold change from non-regainers=26%; p=0.020) and lower methylation of the whole analyzed region of neuropeptide Y (NPY; fold change from non-regainers=-22%; p=0.033), as well as of several individual NPY-promoter CpG sites. Importantly, total baseline NPY methylation was associated with weight-loss regain (r=-0.76; pweight-loss maintenance (odds ratio=0.042 [95% CI 0.01-0.57]; p=0.018), whereas lower total methylation levels in NPY promoter were associated with higher risk of weight regain (odds ratio=14.0 [95% CI 1.13-172]; p=0.039). Therefore, the study of leukocyte methylation levels reflects a putative epigenetic regulation of NPY and POMC, which might be implicated in the weight regain process and be used as biomarkers for predicting weight regain after dieting. © 2013.

    Bariatric surgery is an effective treatment for patients with severe or moderate obesity; however, long-term studies have identified that weight regain occurs post-operatively among a portion of patients. The underlying factors that influence weight regain following bariatric surgery are multifactorial and include endocrine/metabolic alterations, anatomic surgical failure, nutritional indiscretion, mental health issues, and physical inactivity. The extent and significance of these factors is currently uncertain and likely varies between individuals and the operative procedure performed. Multiple observational and non-randomized studies and a few randomized controlled trials have been reported that focus on improving post-operative weight loss. Across all of the behavioral and group support studies, patients in the treatment groups showed either no benefit or modestly greater weight loss than patients in the control groups. There are no randomized controlled trials that have specifically targeted weight regain. Additional clinical research is needed to identify etiological factors and interventional strategies.

    To determine whether depression symptoms or antidepressant medication use predicts weight regain in overweight individuals with impaired glucose tolerance (IGT) who are successful with initial weight loss. A total of 1,442 participants who successfully lost at least 3% of their baseline body weight after 12 months of participation in the randomized controlled Diabetes Prevention Program (DPP) continued in their assigned treatment group (metformin, intensive lifestyle, or placebo) and were followed into the Diabetes Prevention Program Outcome Study (DPPOS). Weight regain was defined as a return to baseline DPP body weight. Participant weight and antidepressant medication use were assessed every 6 months. Depression symptoms (Beck Depression Inventory [BDI] score ≥11) were assessed every 12 months. Only 2.7% of the overall cohort had moderate to severe depression symptoms at baseline; most of the participants with BDI score ≥11 had only mild symptoms during the period of observation. In unadjusted analyses, both depression symptoms (hazard ratio 1.31 [95% CI 1.03-1.67], P = 0.03) and antidepressant medication use at either the previous visit (1.72 [1.37-2.15], P weight regain. After adjustment for multiple covariates, antidepressant use remained a significant predictor of weight regain (P weight, antidepressant use may increase the risk of weight regain.

    Tens of thousands of bariatric surgery patients each year experience sub-optimal weight loss, significant regain, or both. Weight regain can contribute to a worsening of weight-related co-morbidities, and for some, leads to secondary surgical procedures. Poor weight outcomes have been associated with decreased compliance to the recommended postoperative diet. Decreased compliance may be partially due to a lack of psychological skills necessary to engage in healthy eating behaviors over the long term, especially as the effects of surgery (on appetite, hunger, and desire for food) decrease. Many behavioral interventions do not sufficiently address these challenges and often have limited effectiveness. The study aimed to evaluate the feasibility, acceptability, and preliminary effectiveness of a novel 10-week acceptance-based behavioral intervention to stop postoperative weight regain. A sample of bariatric surgery patients (n = 11) who regained at least 10 % of their maximum lost postoperative weight was recruited. All participants received the intervention, which emphasized psychological skills thought to be integral to successful weight control post-surgery. The intervention was shown to be feasible and acceptable, with 72 % retention and high mean rating (4.25 out of 5.00) of program satisfaction among completers. Weight regain was stopped, and even reversed, with a mean total body weight loss of 3.58 ± 3.02 % throughout the 10-week intervention. There were also significant improvements in eating-related and acceptance-related variables. These findings provide initial support for the use of a psychological acceptance-based intervention for weight regain in bariatric surgery patients.

    Dilated gastrojejunal anastomosis aperture is associated with weight regain after Roux-en-Y gastric bypass (RYGB). Transoral outlet reduction (TORe) has proved safe and effective for the treatment of weight regain. The objective of this study was to determine the long-term weight trend and number needed to treat for TORe. This prospective series included consecutive post-RYGB patients with weight regain and a gastrojejunal anastomosis aperture greater than 15 mm. TORe was performed with a full-thickness endoscopic suturing device. A total of 150 patients who had regained 49.9% ± 3.6% of the weight lost after gastric bypass (4.1 ± 0.3 kg/y after nadir) before TORe. At TORe, body mass index was 40.2 ± 0.8 kg/m(2) and weight was 110.7 ± 2.2 kg. At 1 year, weight loss was 10.5 ± 1.2 kg or 24.9 ± 2.6% excess weight loss (EWL); at 2 years, weight loss was 9.0 ± 1.7 kg or 20.0% ± 6.4% EWL; at 3 years, weight loss was 9.5 ± 2.1 kg or 19.2% ± 4.6% EWL. The number needed to treat for arrest of weight regain was 1.0 at 6 months, 1.1 at 1 year, and 1.2 at 2 and 3 years. The number needed to treat to maintain weight loss of ≥5 kg from TORe was 1.2 at 6 months, 1.5 at 1 year, 1.9 at 2 years, and 2.0 at 3 years. TORe safely and effectively arrested weight regain and provided durable weight loss with a low number needed to treat. Patients with weight regain after RYGB should be evaluated for dilation of the gastrojejunal anastomosis, as TORe can be part of a multidisciplinary strategy to address post-RYGB weight regain.

    What is the impact of intentional weight loss and regain on serum androgens in women? We conducted an ancillary analysis of prospectively collected samples from a randomized controlled trial. The trial involved supervised 10% weight loss (8.5 kg on average) with diet and exercise over 4-6 months followed by supervised intentional regain of 50% of the lost weight (4.6 kg on average) over 4-6 months. Participants were randomized prior to the partial weight regain component to either continuation or cessation of endurance exercise. Analytic sample included 30 obese premenopausal women (mean age of 40 ± 5.9 years, mean baseline body mass index (BMI) of 32.9 ± 4.2 kg/m(2)) with metabolic syndrome. We evaluated sex hormone binding globulin (SHBG), total testosterone (T), free androgen index (FAI), and high molecular weight adiponectin (HMWAdp). Insulin, homeostasis model assessment (HOMA), and quantitative insulin sensitivity check index (QUICKI), and visceral adipose tissue (VAT) measured in the original trial were reanalyzed for the current analytic sample. Insulin, HOMA, and QUICKI improved with weight loss and were maintained despite weight regain. Log-transformed SHBG significantly increased from baseline to weight loss, and then significantly decreased with weight regain. LogFAI and logVAT decreased similarly and increased with weight loss followed by weight regain. No changes were found in logT and LogHMWAdp. There was no significant difference in any tested parameters by exercise between the groups. SHBG showed prominent sensitivity to body mass fluctuations, as reduction with controlled intentional weight regain showed an inverse relationship to VAT and occurred despite stable HMWAdp and sustained improvements with insulin resistance. FAI showed opposite changes to SHBG, while T did not change significantly with weight. Continued exercise during weight regain did not appear to impact these findings.

  15. Weight loss, weight regain and bone health.

    The ideal body image for women these days is being slim but, in the real world, obesity becomes a major health problem even in the developing countries. Overweight, but also underweight, may have associated adverse outcomes in many bodily systems, including the bone. Only a few studies have investigated the consequences of intentional weight loss, then weight regain, on bone metabolism and bone density. It seems that the negative impact of bone loss is not reversed when weight partially rebounds following the end of active intervention programs. Thus the benefits and risks of any weight loss program should be addressed individually, and monitoring of bone parameters is recommended.

  16. Impact of carbohydrates on weight regain.

    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).

    Weight loss is accompanied by several metabolic adaptations that work together to promote rapid, efficient regain. We employed a rodent model of regain to examine the effects of a regular bout of treadmill exercise on these adaptations. Obesity was induced in obesity-prone rats with 16 wk of high-fat feeding and limited physical activity. Obese rats were then weight reduced (approximately 14% of body wt) with a calorie-restricted, low-fat diet and maintained at that reduced weight for 8 wk by providing limited provisions of the diet with (EX) or without (SED) a daily bout of treadmill exercise (15 m/min, 30 min/day, 6 days/wk). Weight regain, energy balance, fuel utilization, adipocyte cellularity, and humoral signals of adiposity were monitored during eight subsequent weeks of ad libitum feeding while the rats maintained their respective regimens of physical activity. Regular exercise decreased the rate of regain early in relapse and lowered the defended body weight. During weight maintenance, regular exercise reduced the biological drive to eat so that it came closer to matching the suppressed level of energy expenditure. The diurnal extremes in fuel preference observed in weight-reduced rats were blunted, since exercise promoted the oxidation of fat during periods of feeding (dark cycle) and promoted the oxidation of carbohydrate (CHO) later in the day during periods of deprivation (light cycle) . At the end of relapse, exercise reestablished the homeostatic steady state between intake and expenditure to defend a lower body weight. Compared with SED rats, relapsed EX rats exhibited a reduced turnover of energy, a lower 24-h oxidation of CHO, fewer adipocytes in abdominal fat pads, and peripheral signals that overestimated their adiposity. These observations indicate that regimented exercise altered several metabolic adaptations to weight reduction in a manner that would coordinately attenuate the propensity to regain lost weight.

    Moderate, long-term weight loss results in the loss of bone mass in overweight or obese premenopausal women. However, whether these changes persist during weight maintenance or regain remains to be determined. Overweight or obese (body mass index: 25.8-42.5 kg/m(2)) women (n=40) with at least two risk factors for the metabolic syndrome participated in this 12-month study that examined the effects of prescribed weight loss and regain, with or without exercise, on bone turnover and on bone mineral density (BMD) in a subset of participants (n=24). During the first 6 month, participants lost ≈ 10% of their initial body weight via energy restriction and supervised aerobic exercise. Following weight loss, participants were randomly assigned to either an exercise or a no exercise treatment for the regain (+50% of weight lost) phase. A one-way (time) repeated measures one-factor analysis of variance (RMANOVA) tested the effects of weight loss on BMD and bone turnover, and a two-way RMANOVA (time, exercise) was used to examine the effects of exercise during weight regain. Hip (P=0.007) and lumbar spine (P=0.05) BMD decreased with weight loss, and remained reduced after weight regain with or without exercise. Likewise, the weight-loss-associated increases in osteocalcin (Pweight regain, independent of exercise. The results of the present study, which is the first to examine changes in bone mass and turnover during carefully controlled weight regain, suggest that weight-loss-induced perturbations in bone mass and turnover persist after partial weight regain, regardless of whether regular weight-bearing aerobic exercise was continued.

    Achieving maintenance of weight loss is crucial to combat obesity. However, most individuals tend to regain weight. Data from successful maintainers show that they remain vigilant and constantly apply techniques to oppose the course of regaining. On the other hand, current advances in obesity research show that the reduced obese state is a state of altered physiology in terms of energy balance. This review describes the physiological adaptations occurring after weight loss that predispose to regaining. Specifically, changes regarding body composition, hormonal background, energy expenditure and control of food intake are discussed. Moreover, metabolites that can act as regain predictors and dietary techniques to oppose regaining are presented. Copyright © 2015 Elsevier Inc. All rights reserved.

    Little is known about the effect of intentional weight loss and subsequent weight regain on cardiometabolic risk factors in older adults. The objective of this study was to determine how cardiometabolic risk factors change in the year following significant intentional weight loss in postmenopausal women, and if observed changes were affected by weight and fat regain. Eighty, overweight and obese, older women (age = 58.8±5.1 years) were followed through a 5-month weight loss intervention and a subsequent 12-month nonintervention period. Body weight/composition and cardiometabolic risk factors (blood pressure; total, high-density lipoprotein, and low-density lipoprotein cholesterol; triglycerides; fasting glucose and insulin; and Homeostatic Model Assessment of Insulin Resistance) were analyzed at baseline, immediately postintervention, and 6- and 12-months postintervention. Average weight loss during the 5-month intervention was 11.4±4.1kg and 31.4% of lost weight was regained during the 12-month follow-up. On average, all risk factor variables were significantly improved with weight loss but regressed toward baseline values during the year subsequent to weight loss. Increases in total cholesterol, triglycerides, glucose, insulin, and Homeostatic Model Assessment of Insulin Resistance during the postintervention follow-up were significantly (p weight and fat mass regain. Among women who regained weight, model-adjusted total cholesterol (205.8±4.0 vs 199.7±2.9mg/dL), low-density lipoprotein cholesterol (128.4±3.4 vs 122.7±2.4mg/dL), insulin (12.6±0.7 vs 11.4±0.7mg/dL), and Homeostatic Model Assessment of Insulin Resistance (55.8±3.5 vs 50.9±3.7mg/dL) were higher at follow-up compared with baseline. For postmenopausal women, even partial weight regain following intentional weight loss is associated with increased cardiometabolic risk. Conversely, maintenance of or continued weight loss is associated with sustained improvement in the cardiometabolic profile.

    Background. Obesity is well known for being associated with significant economic repercussions. Bariatric surgery is the only evidence-based solution to this problem as well as a cost-effective method of addressing the concern. Numerous authors have calculated the cost effectiveness and cost savings of bariatric surgery; however, to date the economic impact of weight regain as a component of overall cost has not been addressed. Methods. The literature search was conducted to elucidate the direct costs of obesity and primary bariatric surgery, the rate of weight recidivism and surgical revision, and any costs therein. Results. The quoted cost of obesity in Canada was $2.0 billion–$6.7 billion in 2013 CAD. The median percentage of bariatric procedures that fail due to weight gain or insufficient weight loss is 20% (average: 21.1% ± 10.1%, range: 5.2–39, n = 10). Revision of primary surgeries on average ranges from 2.5% to 18.4%, and depending on the procedure accounts for an additional cost between $14,000 and $50,000 USD per patient. Discussion. There was a significant deficit of the literature pertaining to the cost of revision surgery as compared with primary bariatric surgery. As such, the cycle of weight recidivism and bariatric revisions has not as of yet been introduced into any previous cost analysis of bariatric surgery. PMID:24454339

    This report describes results from a groundwater data-collection program completed in 2003-2004 by the U.S. Geological Survey in support of the South Platte Decision Support System and in cooperation with the Colorado Water Conservation Board. Two monitoring wells were installed adjacent to existing water-table monitoring wells. These wells were installed as well pairs with existing wells to characterize the hydraulic properties of the alluvial aquifer and shallow Denver Formation sandstone aquifer in and near the Lost Creek Designated Ground Water Basin. Single-well tests were performed in the 2 newly installed wells and 12 selected existing monitoring wells. Sediment particle size was analyzed for samples collected from the screened interval depths of each of the 14 wells. Hydraulic-conductivity and transmissivity values were calculated after the completion of single-well tests on each of the selected wells. Recovering water-level data from the single-well tests were analyzed using the Bouwer and Rice method because test data most closely resembled those obtained from traditional slug tests. Results from the single-well test analyses for the alluvial aquifer indicate a median hydraulic-conductivity value of 3.8 x 10-5 feet per second and geometric mean hydraulic-conductivity value of 3.4 x 10-5 feet per second. Median and geometric mean transmissivity values in the alluvial aquifer were 8.6 x 10-4 feet squared per second and 4.9 x 10-4 feet squared per second, respectively. Single-well test results for the shallow Denver Formation sandstone aquifer indicate a median hydraulic-conductivity value of 5.4 x 10-6 feet per second and geometric mean value of 4.9 x 10-6 feet per second. Median and geometric mean transmissivity values for the shallow Denver Formation sandstone aquifer were 4.0 x 10-5 feet squared per second and 5.9 x 10-5 feet squared per second, respectively.

    Short-term weight loss is accompanied by bone loss in postmenopausal women. The longer-term impact of weight loss on bone in reduced overweight/obese women compared with women who regained their weight was examined in this study using a case-control design. Postmenopausal women (N = 42; mean [SD] body mass index, 28.3 [2.8] kg/m; mean [SD] age, 60.7 [5.5] y) were recruited 2 years after the start of a 6-month weight loss trial; those who maintained their weight (weight loss maintainer [WL-M] group) were matched to a cohort of women who regained their weight (weight loss regainer [WL-R] group). Serum hormones and bone markers were measured in a subset. Bone mineral density (BMD) at the femoral neck, trochanter, spine, radius, and total body, and soft-tissue composition were taken at baseline, 0.5 years, and 2 years. During weight loss, both groups lost 9.3% (3.4%) of body weight, with no significant difference between the groups. After weight loss, weight change was -0.1% (2.7%) and 6.0% (3.3%) in the WL-M (n = 22) and WL-R (n = 20) groups, respectively. After 2 years, both groups lost BMD at the femoral neck and trochanter (P ≤ 0.01), whereas only the WL-M group reduced BMD at the 1/3 radius (P weight reduction-induced bone loss, irrespective of weight regain. These data suggest that the period after weight loss may be an important point in time to prevent bone loss for those who maintain weight and those who regain weight.

    Differences in the interindividual response to dietary intervention could be modified by genetic variation in nutrient-sensitive genes. This study examined single nucleotide polymorphisms (SNPs) in presumed nutrient-sensitive candidate genes for obesity and obesity-related diseases for main and dietary interaction effects on weight, waist circumference, and fat mass regain over 6 mo. In total, 742 participants who had lost ≥ 8% of their initial body weight were randomly assigned to follow 1 of 5 different ad libitum diets with different glycemic indexes and contents of dietary protein. The SNP main and SNP-diet interaction effects were analyzed by using linear regression models, corrected for multiple testing by using Bonferroni correction and evaluated by using quantile-quantile (Q-Q) plots. After correction for multiple testing, none of the SNPs were significantly associated with weight, waist circumference, or fat mass regain. Q-Q plots showed that ALOX5AP rs4769873 showed a higher observed than predicted P value for the association with less waist circumference regain over 6 mo (-3.1 cm/allele; 95% CI: -4.6, -1.6; P/Bonferroni-corrected P = 0.000039/0.076), independently of diet. Additional associations were identified by using Q-Q plots for SNPs in ALOX5AP, TNF, and KCNJ11 for main effects; in LPL and TUB for glycemic index interaction effects on waist circumference regain; in GHRL, CCK, MLXIPL, and LEPR on weight; in PPARC1A, PCK2, ALOX5AP, PYY, and ADRB3 on waist circumference; and in PPARD, FABP1, PLAUR, and LPIN1 on fat mass regain for dietary protein interaction. The observed effects of SNP-diet interactions on weight, waist, and fat mass regain suggest that genetic variation in nutrient-sensitive genes can modify the response to diet. This trial was registered at clinicaltrials.gov as NCT00390637.

    Montemurro is a little centre town located in the Agri Valley (Basilicata Region, Italy) which was affected by two catastrophic events: in the 1842 a very large landslide has damaged great part of the centre and in the 1857 the town was destroyed completely by the "Great Neapolitan Earthquake" (Mallet, 1862), a seismic event having epicenter in the Agri Valley (Cello et al., 2003; Bavusi et al., 2004). Signs of those tragic events can be still found in the fabric of the city. One of these is certainly S. Maria square, a place suspected to house a church before the disastrous events of 1842. This suspicion is supported by a series of evidences: a historical drawing, dating back to before 1842, shows a church in position compatible with the location of the square; in aerial view S. Maria square appears as tear in the fabric of the city; the tales of the erderlies of Montemurro speak about an ancient missing church in the town. Then, in the attempt to resolve the doubt about the presence of the church, a geophysical survey was planned in S. Maria Square with the aim to detect some buried masonry structures related to the church. In this work we selected two active techniques such as the Ground Penetrating Radar (GPR) and the Electrical Resistivity Tomography (ERT). Sixty parallel GPR profiles 0.5 m spaced were gathered in S. Maria Square and in a contiguous street by using a GSSI SIR3000 system with a central frequency antenna of 200 MHz. Processed radargrams showed numerous reflectors and heterogeneities in the subsoil related to manmade objects. Then, a laborious data processing (Nuzzo et al., 2002) allowed to obtain several time-slices showing noticeable reflections compatible with masonry structures. Moreover, two ERT profiles were carried out by using an IRIS Syscal R2 system equipped with a multielectrode cable. The first ERT profile 86 m long and having 44 electrodes 2 m spaced allowed to investigate up to 9 m of depth. The second, overlapped on the previous

    To describe patterns of weight loss and regain and their effect on the pro-inflammatory cytokines IL-6 and TNF-α, and anti-inflammatory cytokines adiponectin and IL-10 during a 24-month weight loss trial. Participants were obese adults (N=66) who lost and regained ≥ 10lb during a 24-month clinical trial of behavioral weight loss treatment. Measurements of cytokines and weight were conducted at baseline, 6, 12, 18, and 24 months. Linear mixed modeling was used to determine percent change in weight and cytokines from baseline. The sample was predominantly female (80.3%) and White (86.4%), with a mean age of 48.4 ± 7.3 years and mean BMI of 34.5 ± 4.4 kg/m(2). At baseline, men had higher waist circumference, body weight, and energy intake, and lower percent body fat and adiponectin. The largest decrease in weight was observed at 6 months with a mean 11% decrease (pweight change interaction on percent change in adiponectin was observed [b(se)=0.9 (0.2), p=.0003], with men having a larger increase in adiponectin with weight loss compared to women. There was a significant effect of weight gain over time with increases in IL-6 [b(se)=0.9 (0.3), p=.001]. Overall, weight loss was significantly associated with improvements in adiponectin and IL-6. Those improvements remained at 24 months, following weight regain. The association between weight change and adiponectin was different between genders. Implementing strategies that support sustained weight loss can help prevent a state of chronic systemic inflammation and its associated adverse effects. Copyright © 2013 Elsevier Inc.

    Dieting is the most common approach to losing weight for the majority of obese and overweight individuals. Restricting intake leads to weight loss in the short term, but, by itself, dieting has a relatively poor success rate for long-term weight reduction. Most obese people eventually regain the weight they have worked so hard to lose. Weight regain has emerged as one of the most significant obstacles for obesity therapeutics, undoubtedly perpetuating the epidemic of excess weight that now affects more than 60% of U.S. adults. In this review, we summarize the evidence of biology's role in the problem of weight regain. Biology's impact is first placed in context with other pressures known to affect body weight. Then, the biological adaptations to an energy-restricted, low-fat diet that are known to occur in the overweight and obese are reviewed, and an integrative picture of energy homeostasis after long-term weight reduction and during weight regain is presented. Finally, a novel model is proposed to explain the persistence of the "energy depletion" signal during the dynamic metabolic state of weight regain, when traditional adiposity signals no longer reflect stored energy in the periphery. The preponderance of evidence would suggest that the biological response to weight loss involves comprehensive, persistent, and redundant adaptations in energy homeostasis and that these adaptations underlie the high recidivism rate in obesity therapeutics. To be successful in the long term, our strategies for preventing weight regain may need to be just as comprehensive, persistent, and redundant, as the biological adaptations they are attempting to counter.

    2016-01-01

    OBJECTIVE Short-term weight loss improves cardiovascular disease (CVD) risk factors. We sought to determine the longer-term effects of maintaining weight loss or, conversely, regaining weight. RESEARCH DESIGN AND METHODS We used data from Action for Health in Diabetes (Look AHEAD), a randomized trial of intensive lifestyle intervention (ILI) compared to a control condition in overweight/obese individuals with type 2 diabetes. ILI participants were grouped according to weight change patterns, as follows: 1) no weight loss (±3% at years 1 and 4); 2) moderate weight loss (3–8% at years 1 and 4); 3) large weight loss (8–20% at years 1 and 4); 4) moderate loss/full regain (3–8% at year 1/±3% at year 4); 5) large loss/full regain (8–20% at year 1/± 3% year 4); and 6) large loss/partial regain (8–20% at year 1/3–8% at year 4) and changes in CVD risk factors were compared. RESULTS Adjusting for baseline differences and medication use, larger weight losses produced greater improvements in HbA1c, systolic blood pressure, HDL cholesterol, and triglycerides at years 1 and 4 (all P ≤ 0.02). Despite maintenance of weight loss, HbA1c levels worsened between years 1 and 4, and remained below baseline only in those with large weight losses. We found no negative associations of losing and regaining weight relative to not having lost weight. Moreover, those who had large initial weight loss but full regain of weight had greater improvements in HbA1c levels at year 4 than those with smaller or no initial weight loss. CONCLUSIONS Larger initial weight loss should be encouraged in individuals with type 2 diabetes, despite the possibility of regain. PMID:27271190

    Body weight regain often causes failure of obesity therapies while the underlying mechanism remains largely unknown. In this study, we report that immune cells, especially CD4+ T cells, mediate the 'memory' of previous obese status. In a weight gain-loss-regain model, we found that C57BL/6J mice with an obesity history showed a much faster rate of body weight regain. This obesity memory could last for at least 2 months after previously obese mice were kept at the same body weight as non-obese mice. Surprisingly, such obesity memory was abrogated by dexamethasone treatment, whereas immunodeficient Rag1(-/-) and H2A(-/-) mice failed to establish such memory. Rag1(-/-) mice repossessed the obesity memory when immune cells or CD4+ T cells isolated from previously obese mice were transferred. Furthermore, depletion of CD4+ T cells led to obesity memory ablation. Taken together, we conclude that CD4+ T cells mediate obesity memory and promote weight regain.Cellular &Molecular Immunology advance online publication, 19 June 2017; doi:10.1038/cmi.2017.36.

    The extracellular matrix (ECM) of adipocytes is important for body weight regulation. Here, we investigated whether genetic variation in ECM-related genes is associated with weight regain among participants of the European DiOGenes study. Overweight and obese subjects (n = 469, 310 females, 159...... males) were on an 8-week low-calorie diet with a 6-month follow-up. Body weight was measured before and after the diet, and after follow-up. Weight maintenance scores (WMS, regained weight as percentage of lost weight) were calculated based on the weight data. Genotype data were retrieved for 2903 SNPs...... corresponding to 124 ECM-related genes. Regression analyses provided us with six significant SNPs associated with the WMS in males: 3 SNPs in the POSTN gene and a SNP in the LAMB1, COL23A1, and FBLN5 genes. For females, 1 SNP was found in the FN1 gene. The risk of weight regain was increased by: the C...

  1. Physiological adaptations to weight loss and factors favouring weight regain.

    Obesity is a major global health problem and predisposes individuals to several comorbidities that can affect life expectancy. Interventions based on lifestyle modification (for example, improved diet and exercise) are integral components in the management of obesity. However, although weight loss can be achieved through dietary restriction and/or increased physical activity, over the long term many individuals regain weight. The aim of this article is to review the research into the processes and mechanisms that underpin weight regain after weight loss and comment on future strategies to address them. Maintenance of body weight is regulated by the interaction of a number of processes, encompassing homoeostatic, environmental and behavioural factors. In homoeostatic regulation, the hypothalamus has a central role in integrating signals regarding food intake, energy balance and body weight, while an 'obesogenic' environment and behavioural patterns exert effects on the amount and type of food intake and physical activity. The roles of other environmental factors are also now being considered, including sleep debt and iatrogenic effects of medications, many of which warrant further investigation. Unfortunately, physiological adaptations to weight loss favour weight regain. These changes include perturbations in the levels of circulating appetite-related hormones and energy homoeostasis, in addition to alterations in nutrient metabolism and subjective appetite. To maintain weight loss, individuals must adhere to behaviours that counteract physiological adaptations and other factors favouring weight regain. It is difficult to overcome physiology with behaviour. Weight loss medications and surgery change the physiology of body weight regulation and are the best chance for long-term success. An increased understanding of the physiology of weight loss and regain will underpin the development of future strategies to support overweight and obese individuals in their efforts

    Previously, we reported significant bone mineral density (BMD) loss in postmenopausal women after modest weight loss. It remains unclear whether the magnitude of BMD change in response to weight loss is appropriate (i.e., proportional to weight loss) and whether BMD is recovered with weight regain. We now report changes in BMD after a 1-year follow-up. Subjects (n = 23) in this secondary analysis were postmenopausal women randomized to placebo as part of a larger trial. They completed a 6-month exercise-based weight loss program and returned for follow-up at 18 months. Dual-energy X-ray absorptiometry (DXA) was performed at baseline, 6, and 18 months. At baseline, subjects were aged 56.8 ± 5.4 years (mean ± s.d.), 10.0 ± 9.2 years postmenopausal, and BMI was 29.6 ± 4.0 kg/m2. They lost 3.9 ± 3.5 kg during the weight loss intervention. During follow-up, they regained 2.9 ± 3.9 kg. Six months of weight loss resulted in a significant decrease in lumbar spine (LS) (−1.7 ± 3.5%; P = 0.002) and hip (−0.04 ± 3.5%; P = 0.03) BMD that was accompanied by an increase in a biomarker of bone resorption (serum C-terminal telopeptide of type I collagen, CTX: 34 ± 54%; P = 0.08). However, weight regain was not associated with LS (0.05 ± 3.8%; P = 0.15) or hip (−0.6 ± 3.0%; P = 0.81) bone regain or decreased bone resorption (CTX: −3 ± 37%; P = 0.73). The findings suggest that BMD lost during weight reduction may not be fully recovered with weight regain in hormone-deficient, postmenopausal women. Future studies are needed to identify effective strategies to prevent bone loss during periods of weight loss. PMID:21852813

    Laparoscopic adjustable gastric banding (LAGB) surgery is the safest yet least effective method for massive weight loss. Thirty to 50 percent of patients undergoing LAGB will regain part of their lost weight. To evaluate the effect of body contouring plastic surgery (BCPS) following LAGB on long-term body mass index (BMI) control. Department of Surgery A, Soroka University Medical Center, Beer-Sheva, Israel. A retrospective cohort study of patients aged 18-50 years, who underwent LAGB surgery between 1997 and 2007, was performed. Out of 2405 patients undergoing LAGB during those years, 861 were excluded and 1544 were recruited by phone. The final group included 72 patients matched for age and gender. Long-term weight regain was evaluated and compared between a group of patients who underwent subsequent body contouring plastic surgery (LBCPS) and a group of LAGB only (LAGBO). Groups were matched for age, gender, and pre-operative body mass index (BMI). LBCPS (n = 18) had lower endpoint BMI and BMI regain percentage compared with LAGBO (n = 54) (24.64 ± 3.76 vs. 31.0 ± 7.2 kg/m(2), p regain over 25% and BMI ≥30 kg/m(2) (HR = 0.19, p = 0.025; HR = 0.13, p = 0.046, respectively). When compared with patients who did not undergo BCPS following LAGB, patients who underwent BCPS following LAGB had improved long-term BMI control.

    While the sexual temptation of Paradise Regained is tactful, it is also characteristically Miltonic in its daring. Despite its decorous presentation, the temptation is exceedingly bold in that it is not merely a heterosexual temptation but a homosexual one as well. Acknowledgement of the homosexual lure in the brief epic is essential to understanding the dynamics of the celebrated banquet scene and to appreciating the comprehensiveness of Milton's trial of the Son's humanity. Such a recognition also helps place in perspective the alleged misogyny of Paradise Regained, even as it also reveals the complexity of Milton's poetic technique, particularly his ability to work by indirection and implication and to exploit classical and biblical sources. Although Jesus rejects the homosexual temptation (as He does the heterosexual one), He does not condemn homosexuality. Milton's incorporation of a homosexual temptation provides evidence of his sophisticated recognition of the range of fully human sexual responses.

    Roux-en-Y gastric bypass (RYGB) surgery is an established modality for the treatment of morbid obesity. However, approximately one-quarter of patients experience weight regain after initially successful weight loss. Endoscopic therapy targeting the gastric remnant pouch represents a novel potential strategy to re-induce weight loss in this population. We performed a pilot trial of radiofrequency ablation (RFA) of the gastric remnant pouch after RYGB to determine feasibility, safety, and efficacy for weight loss. We identified patients who had undergone RYGB, achieved >40% excess body weight loss (EBWL), and then regained >25% of lost weight. RFA was applied to the gastrojejunal anastomosis and the entire surface area of the gastric remnant pouch. Treatment was repeated at 4 and 8 months if patients did not meet specified weight loss targets. Weekly weights were obtained for 12 months. The primary efficacy outcome was percent EBWL at 12 months, compared with baseline. Twenty-five patients were enrolled at 4 centers. Mean (± standard deviation [SD]) age was 45.4 ± 9.1 years, and 84% (21/25) were female. Mean (± SD) baseline body mass index was 40.2 ± 7.8. Twenty-two of 25 patients completed 12 months of follow-up. At 12 months, median (± SD) EBWL was 18.4% (interquartile ratio 10.8, 33.7; P weight loss was seen at 3.5 months (P weight loss over the 12-month period (P = .013). Two patients had serious adverse events requiring hospitalization. RFA of the gastric remnant pouch in patients with weight regain after RYGB resulted in significant reductions in excess body weight with an acceptable safety profile. Continued weight loss was observed after each RFA treatment. Further clinical trials in well-selected populations are warranted to determine the optimal number and frequency of RFA treatments and to assess durability of weight loss.

  9. Modeling Being "Lost": Imperfect Situation Awareness

    Middleton, Victor E.

    2011-01-01

    Being "lost" is an exemplar of imperfect Situation Awareness/Situation Understanding (SA/SU) -- information/knowledge that is uncertain, incomplete, and/or just wrong. Being "lost" may be a geo-spatial condition - not knowing/being wrong about where to go or how to get there. More broadly, being "lost" can serve as a metaphor for uncertainty and/or inaccuracy - not knowing/being wrong about how one fits into a larger world view, what one wants to do, or how to do it. This paper discusses using agent based modeling (ABM) to explore imperfect SA/SU, simulating geo-spatially "lost" intelligent agents trying to navigate in a virtual world. Each agent has a unique "mental map" -- its idiosyncratic view of its geo-spatial environment. Its decisions are based on this idiosyncratic view, but behavior outcomes are based on ground truth. Consequently, the rate and degree to which an agent's expectations diverge from ground truth provide measures of that agent's SA/SU.

    Full Text Available Abstract The 'Copenhagen Accord' fails to deliver the political framework for a fair, ambitious and legally-binding international climate agreement beyond 2012. The current climate policy regime dynamics are insufficient to reflect the realities of topical complexity, actor coalitions, as well as financial, legal and institutional challenges in the light of extreme time constraints to avoid 'dangerous' climate change of more than 2°C. In this paper we analyze these stumbling blocks for international climate policy and discuss alternatives in order to regain momentum for future negotiations.

    The Austrian State medical universities had to change their admission system in 2005. Until this year admission to medical studies was unrestricted. Innsbruck Medical University chose the Eignungstest für das Medizinstudium in der Schweiz (EMS) aptitude test for admission testing. Did the implementation of a selection process affect the academic performance and drop-out rates of students according to gender? Two groups of students were compared: 'open admission' (2002-2004), and 'selected' (2006-2009). Academic performance was tested according to results in the final exams after year 1 (SIP 1; SIP, summative integrierte Prüfung) and after year 3 (SIP 3). Drop-out rates were recorded using the registration system of the university. Both, male and female 'selected' students had a higher passing rate regarding SIP 1 and they passed SIP 1 in shorter time and using fewer attempts than the open admission group. The percentage in passing SIP 3 did not change due to change in admission. The drop-out rates were significantly reduced for male and female students. 'Unselected' female students had a significantly higher drop-out ratio than 'unselected' male counterparts. After EMS testing, the drop-out ratios of female and male students were not significantly different. Selected applicants were more able and better motivated to study medicine.

    Cultural Heritage all over the world is at high risk. Natural and human activities endanger the current state of monuments and sites, whereas many of them have already been destroyed especially during the last years. Preventive actions are of utmost importance for the protection of human memory and the prevention of irreplaceable. These actions may be carried out either in situ or virtually. Very often in situ preventive, or protective or restoration actions are difficult or even impossible, as e.g. in cases of earthquakes, fires or war activity. Digital preservation of cultural heritage is a challenging task within photogrammetry and computer vision communities, as efforts are taken to collect digital data, especially of the monuments that are at high risk. Visit to the field and data acquisition is not always feasible. To overcome the missing data problem, crowdsourced imagery is used to create a visual representation of lost cultural heritage objects. Such digital representations may be 2D or 3D and definitely help preserve the memory and history of the lost heritage. Sometimes they also assist studies for their reconstruction. An initiative to collect imagery data from the public and create a visual 3D representation of a recently destroyed stone bridge almost 150 years old is being discussed in this study. To this end, a crowdsourcing platform has been designed and the first images collected have been processed with the use of SfM algorithms.

    Full Text Available This paper explores the potential for using alternative forms of inscriptive practice to describe the urban space of the Tokyo Subway. I begin with an account of the process of getting lost in Shinjuku Subway Station in the heart of Tokyo. This station represents a limit condition of place, being dense and complex beyond the powers of traditional architectural representation. The station is explored through serial translations, beginning with narrative, moving to a flowchart diagram, Laban dance notation, recurring motifs and archetypes, architectural drawing, photography, and cartography. As Claudia Brodsky Lacour and Tim Ingold describe, the form our inscriptive practices take are crucial to the ways in which we conceptualise those places. How much of the experience of a place is lost in the traditional inscriptive practices of the architect? This description of the urban space of the Tokyo subway forms the basis for an extended study exploring the description of this experience of place, and the power of such description to theorise space. The ultimate aim of this is to shift the focus of urban design away from geometric principles and towards the experiences that might be enjoyed in such places.

    Obesity is a serious and growing public health problem in the United States and the world. While weight loss is associated with significant benefits in obesity-related co-morbidities, successful long-term weight loss maintenance is extremely difficult. This limited success is primarily due to biologic mechanisms that clearly favor weight regain. The weight-reduced state is associated with not only reductions in energy expenditure and changes in substrate metabolism but also in increased energy intake. Measures of appetite (increased hunger, reduced satiety) clearly change with weight loss. These changes in appetite may be mediated by alterations of peripheral appetite-related signals, such as leptin and meal-related gut peptides, promoting energy intake. Furthermore, significant changes in the neuronal response to food-related cues in the weight-reduced state have also been shown, stressing the importance of the interactions between homeostatic and non-homeostatic regulation of energy intake. In summary, the weight-reduced state is clearly associated with a dysregulation of energy balance regulation, resulting in a milieu promoting weight regain, and thus being one of the major obstacles of "treating" obesity and reducing its comorbidities. This paper will review the adaptations in the central regulation of energy intake that occur after weight-loss or in the weight-reduce state in humans, including changes in peripheral appetite-related signals and neuroimaging studies examining the brain's response to weight loss.

    There is a need to identify evidenced-based obesity treatments that are effective in maintaining lost weight. Weight loss results in reductions in energy expenditure, including spontaneous physical activity (SPA) which is defined as energy expenditure resulting primarily from unstructured mobility-related activities that occur during daily life. To date, there is little research, especially randomized, controlled trials, testing strategies that can be adopted and sustained to prevent declines in SPA that occur with weight loss. Self-monitoring is a successful behavioral strategy to facilitate behavior change, so a provocative question is whether monitoring SPA-related energy expenditure would override these reductions in SPA, and slow weight regain. This study is a randomized trial in older, obese men and women designed to test the hypothesis that adding a self-regulatory intervention (SRI), focused around self-monitoring of SPA, to a weight loss intervention will result in less weight and fat mass regain following weight loss than a comparable intervention that lacks this self-regulatory behavioral strategy. Participants (n=72) are randomized to a 5-month weight loss intervention with or without the addition of a behavioral component that includes an innovative approach to promoting increased SPA. Both groups then transition to self-selected diet and exercise behavior for a 5-month follow-up. Throughout the 10-month period, the SRI group is provided with an intervention designed to promote a SPA level that is equal to or greater than each individual's baseline SPA level, allowing us to isolate the effects of the SPA self-regulatory intervention component on weight and fat mass regain.

    Nostalgia for the Soviet Union is a major social phenomenon in Russia today due to the irrevocable losses of the recent past in which Soviet citizens involuntarily became immigrants in their own country. With reference to discussions of nostalgia in philosophical and psychoanalytic literature, I suggest that nostalgia may represent either a defensive regression to the past or a progressive striving for wholeness through re-connecting with what has been lost in the service of a greater integration. I compare this with the processes of adaptation seen in immigrants and provide a clinical illustration of a young man coming to terms with loss and change in the post-Soviet era. When nostalgia is recognized as a legitimate emotional experience it may facilitate mourning and enable the integration of the past with the present and the development of a new identity.

    To explore how surgical reconstruction of grip affects everyday life for patients with tetraplegia, with special emphasis on patients perspective of their perceived changes. Qualitative method. Eleven people (aged 22-73) with tetraplegia who had undergone surgical reconstruction to restore grip function. Qualitative interviews were conducted 7-17 months after surgery and analysed using Grounded theory. The core concept describing the participants experienced gains after grip reconstructive surgery was "enhanced independence". It was associated with changes in both practical and psychological aspects of independence. Practical aspects identified were: "perform more activities", "smoother everyday life", "renewed ability to participate in social activities", "less dependence on assistance" and "less restricted by physical environment". Psychological aspects of independence included "regained privacy", "increased manageability", "regained identity", "recapture a part of the body" and "share positive experiences with relatives and friends". Encompassing all categories was the concept "self-efficacy in hand control". It was seen as a result included in the enhanced independency core but also as an important factor for the development of all the other categories. Participants in this study experienced enhanced independence after grip reconstructive surgery and rehabilitation. The enhanced independence included both practical and physical aspects and it influenced all domains using the International Classification of Function, Disability and Health model; body function and structure, activities, participation, personal factors and environmental factors. Implications for Rehabilitation Patients with tetraplegia experience grip reconstruction as a useful intervention, an enhanced independence, related to their improved hand control. The increased hand control impacted not only physical aspects but also practical and psychological aspects. It also influenced social and

    Early loss of permanent anterior teeth in growing children has a psychological impact on the child. Anterior teeth are important both aesthetically and functionally. When a permanent tooth is lost, the teeth adjacent to the created space tend to migrate into the space resulting in the space loss. Management of regaining space with the removable appliance always depends on child cooperation for using the appliance as well as for the recall visits. The advantages of fixed appliances over the removable appliances are minimal discomfort, reduced need for patient cooperation and increased control of tooth movements in all three directions of space. Thus, a short course of fixed appliance like the modified 2 by 3 fixed appliance followed by fixed functional space maintainer could be an ideal treatment option for such cases.

    Two strains of Babesia bovis that were known to have lost infectivity for the normal tick vector, Boophilus microplus, due to repeated blood passaging in cattle, were studied to determine whether the strains would regain infectivity for ticks during longstanding infections. Parasitaemias were monitored in 4 chronically infected calves that were regularly infested with ticks. Two strains of ticks known to be susceptible to infection with unmodified strains of B. bovis were used. Adult female ticks that dropped from the calves on days that a parasitaemia was evident were tested for B. bovis infection. Sixty-six batches of ticks collected up to 279 days after infection of the calves produced 14 pools of larvae, none of which transmitted infection. Primary infections established from the chronic infections by subinoculation at 200, 259 and 333 days after infection of the calves were also not transmitted by ticks.

    This study aims to investigate weight regain and the associated variables 10 years after Roux-en-Y gastric bypass. This retrospective study recruited patients submitted to Roux-en-Y gastric bypass (N = 166) for a 10-year follow-up. The following variables were investigated: body mass index (BMI), percentage of excess weight loss (%EWL), weight regain (WR), and percentage of weight regain (%WG). The chi-squared test or Fisher's exact test compared proportions, and the Mann-Whitney test compared numerical measurements between the groups. Analysis of variance (ANOVA) compared the measurements over time. The significance level was set at 5 %. The sample had a mean age of 39.59 ± 11.69 years, and females prevailed (71.7 %). In the long-term follow-up, 41 % of the patients had weight regain. Seventy-two months after surgery, excess weight, preoperative BMI, gender, age, nutritional monitoring, and iron deficiency did not explain weight regain. Younger patients had regained significantly more weight 96 (p = 0.008) and 120 months (p = 0.004) after surgery than older patients. Patients who regained weight had ferritin weight regain, which increased over time. Age, iron deficiency, and time since surgery were associated with weight regain in the long-term follow-up.

    Lost in Translation? Introducing Planetary Boundaries into Social Systems. Fritz Reusswig, Wiebke Lass Potsdam Institute for Climate Impact Research, Potsdam, Germany Identifying and quantifying planetary boundaries by interdisciplinary science efforts is a challenging task—and a risky one, as the 1972 Limits to Growth publication has shown. Even if we may be assured that scientific understanding of underlying processes of the Earth system has significantly improved since then, the challenge of translating these findings into the social systems of the planet remains crucial for any kind of action, and in many respects far more challenging. We would like to conceptualize what could also be termed a problem of coupling social and natural systems as a nested set of social translation processes, well aware of the limited applicability of the language-related translation metaphor. Societies must, first, perceive these boundaries, and they have to understand their relevance. This includes, among many other things, the organization of transdisciplinary scientific cooperation. They will then have to translate this understood perception into possible actions, i.e. strategies for different local bodies, actors, and institutional settings. This implies a lot of 'internal' translation processes, e.g. from the scientific subsystem to the mass media, the political and the economic subsystem. And it implies to develop subsystem-specific schemes of evaluation for these alternatives, e.g. convincing narratives, cost-benefit analyses, or ethical legitimacy considerations. And, finally, societies do have to translate chosen action alternatives into monitoring and evaluation schemes, e.g. for agricultural production or renewable energies. This process includes the continuation of observing and re-analyzing the planetary boundary concept itself, as a re-adjustment of these boundaries in the light of new scientific insights cannot be excluded. Taken all together, societies may well

    The extracellular matrix (ECM) of adipocytes is important for body weight regulation. Here, we investigated whether genetic variation in ECM-related genes is associated with weight regain among participants of the European DiOGenes study. Overweight and obese subjects (n = 469, 310 females, 159 males) were on an 8-week low-calorie diet with a 6-month follow-up. Body weight was measured before and after the diet, and after follow-up. Weight maintenance scores (WMS, regained weight as percentage of lost weight) were calculated based on the weight data. Genotype data were retrieved for 2903 SNPs corresponding to 124 ECM-related genes. Regression analyses provided us with six significant SNPs associated with the WMS in males: 3 SNPs in the POSTN gene and a SNP in the LAMB1, COL23A1, and FBLN5 genes. For females, 1 SNP was found in the FN1 gene. The risk of weight regain was increased by: the C/C genotype for POSTN in a co-dominant model (OR 8.25, 95 % CI 2.85-23.88) and the T/C-C/C genotype in a dominant model (OR 4.88, 95 % CI 2.35-10.16); the A/A genotype for LAMB1 both in a co-dominant model (OR 18.43, 95 % CI 2.35-144.63) and in a recessive model (OR 16.36, 95 % CI 2.14-124.9); the G/A genotype for COL23A1 in a co-dominant model (OR 3.94, 95 % CI 1.28-12.10), or the A-allele in a dominant model (OR 2.86, 95 % CI 1.10-7.49); the A/A genotype for FBLN5 in a co-dominant model (OR 13.00, 95 % CI 1.61-104.81); and the A/A genotype for FN1 in a recessive model (OR 2.81, 95 % CI 1.40-5.63). Concluding, variants of ECM genes are associated with weight regain after weight loss in a sex-specific manner.

    Roux-en-Y gastric bypass (RYGB) is a highly effective treatment for obesity and results in long-term weight loss and resolution of co-morbidities. However, weight regain may occur as soon as 1-2 years after surgery. This retrospective study aimed to investigate the prevalence of weight regain and possible preoperative predictors of this phenomenon after RYGB. An academic medical center in the United States. A total of 1426 obese patients (15.8% male) who underwent RYGB during January 2000 to 2012 and had at least a 2-year follow-up were reviewed. We included only patients who were initially successful, having achieved at least 50% excess weight loss at 1 year postoperatively. Patients were then categorized into either the weight regain group (WR) or sustained weight loss (SWL) group based upon whether they gained≥15% of their 1-year postoperative weight. Weight regain was observed in 244 patients (17.1%). Preoperative body mass index was similar between groups. Body mass index was significantly higher and percent excess weight loss was significantly lower in the WR group (Pweight regain was 19.5±9.3 kg and-.8±8.5 in the WR and SWL groups, respectively (Pweight loss. Moreover, a longer duration after RYGB was associated with weight regain. Multivariate analysis revealed that younger age was a significant predictor of weight regain even after adjusting for time since RYGB. The present study confirmed that a longer interval after RYGB was associated with weight regain. Younger age was a significant predictor of weight regain even after adjusting for time since RYGB. The findings of this study underscore the complexity of the mechanisms underlying weight loss and regain after RYGB. Future prospective studies are needed to further explore the prevalence, predictors, and mechanisms of weight regain after RYGB. Copyright © 2016 American Society for Bariatric Surgery.

    Lost circulation is the loss of drilling fluid from the wellbore to fractures or pores in the rock formation. In geothermal drilling, lost circulation is often a serious problem that contributes greatly to the cost of the average geothermal well. The Lost Circulation Technology Development Program is sponsored at Sandia National Laboratories by the US Department of Energy. The goal of the program is to reduce lost circulation costs by 30--50% through the development of mitigation and characterization technology. This paper describes the technical progress made in this program during the period April 1991--March 1992. 8 refs.

    Weight reduction in overweight and obese individual’s results in physiological and behavioral changes that make the prevention of weight regain more difficult than either initial weight loss or the prevention of weight gain. Exercise is recommended for the prevention of weight regain by both governmental agencies and professional organizations. To date, the effectiveness of exercise recommendations for the prevention of weight regain has not been evaluated in a properly designed, adequately powered trial. Therefore, we will conduct a randomized trial to evaluate the effectiveness of 3 levels of exercise on the prevention of weight regain, in initially overweight and obese sedentary men and women. Participants will complete a 3 month weight loss intervention of decreased energy intake (EI) and increased exercise (100 minutes/week). Participants achieving clinically significant weight loss (≥ 5% of initial weight), will then be randomly assigned to 12 months of verified exercise at 3 levels (150, 225 or 300 minutes/week). This study will evaluate: 1) the effectiveness of 3 levels of exercise on the prevention of weight regain over 12 months subsequent to clinically significant weight loss (≥ 5%); 2) gender differences in weight regain in response to 3 levels of exercise; and 3) potential compensatory changes in daily physical activity (PA) and EI on weight regain in response to 3 levels of exercise. Results of this investigation will provide information to develop evidenced based recommendations for the level of exercise associated with the prevention of weight regain. PMID:24012915

By attending to the history...... of this organization-phobia, the paper argues that OT has become increasingly incapable of speaking about its core object. I show how organizations went from being conceptualized as entities of major importance to becoming theoretically deconstructed and associated with all kinds of ills. Through this history......, organizations as distinct entities have been rendered so problematic that they have gradually come to be removed from the center of OT. The costs of this have been rather significant. Besides undermining the grounds that gave OT intellectual credibility and legitimacy to begin with, the organization-phobia...

    Failing balance and increased liability to falling are common complaints among hemiplegic subjects. During rehabilitation much effort is put into regaining postural stability. To describe the regaining of postural stability during rehabilitation for the first year following stroke in hemiplegic patients Twenty-six patients were included within 5 days of suffering a stroke resulting from a CT-verified clearly defined thromboembolic lesion, localized in the vascular bed of middle cerebral artery on either side. Posturographic evaluation of sway was performed on a commercially available force plate system (Balance Master Pro). Measured parameters included per cent maximum stability (PMS), per cent ankle strategy (AST), and average angular velocity (AVE). An additional parameter was derived by calculating the slope (SLP) of the linear relationship between stability and ankle strategy. SLP reflects the predisposition of the stroke patient to keep using ankle strategy when faced with increasingly difficult balance tasks. The presence of familiarization to the measurement method was examined by including a preliminary measurement not otherwise included in the analysis of changes during the first year of follow-up. The temporal evolvement of sway was described by measuring sway parameters 1, 2, 4, 8 and 52 weeks following stroke. The proportions of the variation in sway caused by measurement error and between patients were compared. All parameters improved over time, as demonstrated by significant improvements from each of week 1, 2, 4 and 8 to week 52. There was evidence of familiarisation for PMS, AST and AVE, but not for SLP. Estimation of variance components showed that between patient variation accounts for between two-thirds and four-fifths of the total variation. A considerable part of this variation was caused by individual differences in the temporal improvement of sway over time. Patients considered the evaluation of postural sway demanding and time consuming

    We explore the problem of atomic collapse in graphene by monopole impurities, both electric and magnetic, within the context of supersymmetric quantum mechanics. For electric impurities, upon factorizing the radial Dirac Hamiltonian and identifying the supercharges, existence of a critical charge that makes the ground state {\\em fall-into-the-center} translates into lost of unitarity for the corresponding Hamiltonian. For the problem of magnetic monopole impurities, preservation of unitarity for all values of the parameters of the corresponding potential translates into the absence of atomic collapse in this case.

    Healthcare represents a key area in the public agenda. In the case of Chile, this central part of citizen demands has emerged with an increasing criticism of the health system, its actors and institutions, while a major democratic and legitimacy crisis in Chilean society unfolds. The starting point of this analysis is the link between the critical and widespread societal dissatisfaction with the legitimacy crisis in the health sector. There is an interdependence and parallelism between these two different aspects of the crisis. The analysis is built around the dimensions of trust and legitimacy as a potential driver of the conflict, taking as an analytical framework the socio-political matrix. Conceptual elements around the ideas of trust and legitimacy in public policies are reviewed. This article focuses on recent situations surrounding the dynamics of the Chilean health system such as the rise of the Instituciones de Salud Previsional (ISAPRE) and the market-driven health system, the failed health care reform of the last decade, conflicts of interest in the formulation of public policies, loss of legitimacy of healthcare authorities, and the role of the health professionals in this process. Finally, a discussion arises seeking to regain public trust as a central issue for the future development and sustainability of health policies.

    Little is known about the experiences of operable lung cancer patients during treatment in a clinical setting based on fast-track surgery. The study aimed to explore (1) the embodied meaning of illness in patients with operable lung cancer during treatment to 4 months after surgery and (2) patterns of change over time that may affect the patients' daily lives. Twenty patients referred for lung cancer surgery were interviewed three times, corresponding to potential critical transition points following surgery: hospitalisation; hospital-to-home transition; and resumption of daily life activities. Data collection, analysis and interpretation followed a phenomenological hermeneutical approach inspired by Ricoeur and the theoretical framework was grounded in Merleau-Ponty's phenomenology of perception. The findings reveal the process patients went through in regaining familiarity with their own body after lung cancer treatment. Through the post-operative trajectory the patients' resumption of daily activities involved adjusting to a new awareness of everyday life, physical restrictions and their perception of themselves. The findings are expressed in four sub-themes: (1) perceptions of embodied alterations; (2) transformation of embodied structures in the transition from hospital to home was unexpectedly challenging; (3) embodied perceptions of the intersubjective world; and (4) transforming embodied disruptions into bodily awareness. Patients experienced a smooth treatment trajectory regarding physical consequences of illness and treatment which might be due to the fast-track surgery. Clinicians should be aware of patients' experiences of illness to facilitate patient reconstitution of own identity.

    Professional musicians are an excellent model of long-term motor learning effects on structure and function of the sensorimotor system. However, intensive motor skill training has been associated with task-specific deficiency in hand motor control, which has a higher prevalence among musicians (musician's dystonia) than in the general population. Using a transcranial magnetic stimulation paradigm, we previously found an expanded spatial integration of proprioceptive input into the hand motor cortex [sensorimotor organization (SMO)] in healthy musicians. In musician's dystonia, however, this expansion was even larger. Whereas motor skills of musicians are likely to be supported by a spatially expanded SMO, we hypothesized that in musician's dystonia this might have developed too far and now disrupts rather than assists task-specific motor control. If so, motor control should be regained by reversing the excessive reorganization in musician's dystonia. Here, we test this hypothesis and show that a 15 min intervention with proprioceptive input (proprioceptive training) restored SMO in pianists with musician's dystonia to the pattern seen in healthy pianists. Crucially, task-specific motor control improved significantly and objectively as measured with a MIDI (musical instrument digital interface) piano, and the amount of behavioral improvement was significantly correlated to the degree of sensorimotor reorganization. In healthy pianists and nonmusicians, the SMO and motor performance remained essentially unchanged. These findings suggest that the differentiation of SMO in the hand motor cortex and the degree of motor control of intensively practiced tasks are significantly linked and finely balanced. Proprioceptive training restored this balance in musician's dystonia to the behaviorally beneficial level of healthy musicians.

    This study explores the role of dichotomous thinking on eating behavior and its association with restraint eating and weight regain in a wide range of people. In a web-based survey with 241 adults, dichotomous thinking and behavioral outcomes related to eating (restraint eating, weight regain, body mass index, dieting) were assessed. Results showed that eating-specific dichotomous thinking (dichotomous beliefs about food and eating) mediates the association between restraint eating and weight regain. We conclude that holding dichotomous beliefs about food and eating may be linked to a rigid dietary restraint, which in turn impedes people's ability to maintain a healthy weight. © The Author(s) 2015.

    To assess the extent to which initial, intentional weight loss-associated improvements in glucose tolerance and insulin action are diminished with weight regain. 138 overweight and obese (BMI: 32.4±3.9kg/m(2)), adults (59.0±9.7 years), with pre-diabetes were followed through a 6-month weight loss intervention and subsequent 18-month weight maintenance period, or usual care control condition. Longitudinal change in weight (baseline, 6, 24 months) was used to classify individuals into weight pattern categories (Loser/Maintainer (LM), n= 50; Loser/Regainer (LR), n=51; and Weight Stable (WS), n=37). Fasting plasma glucose (FPG), insulin, and insulin resistance (HOMA-IR) were measured at baseline, 6, 12, 18 and 24 months and model adjusted changes, by weight pattern category, were assessed. LMs and LRs lost 8.3±4.7kg (8.7±4.5%) and 9.6±4.7kg (10.2±4.7%) during the first 6 months, respectively. LM continued to lose 1.1±3.4kg over the next 18 months (9.9±6.5% reduction from baseline; pregained 6.5±3.7kg (3.3±5.3% reduction from baseline; pWeight change was directly associated with change in all DM risk factors (all pweight (from baseline to 24 months) achieved in the LR group, 24-month changes in FPG, insulin, and HOMA-IR did not differ between WS and LR groups. Conversely, LM saw sustained improvements in all measured DM risk factors. Significant weight loss followed by weight loss maintenance is associated with sustained improvements in FPG, insulin, and HOMA-IR; conversely, even partial weight regain is associated with regression of initial improvements in these risk factors towards baseline values.

    A certain weight gain occurs after obesity surgery compared to the lower weight usually observed between 18 and 24 months postsurgery. The objective of this study was to evaluate weight regain in patients submitted to gastric bypass over a 5-year follow-up period. A longitudinal prospective study was conducted on 782 obese patients of both genders. Only patients with at least 2 years of surgery were included. The percentage of excess body mass index (BMI) loss at 24, 36, 48, and 60 months postsurgery was compared to the measurements obtained at 18 months after surgery. Surgical therapeutic failure was also evaluated. Percent excess BMI loss was significant up to 18 months postsurgery (p < 0.001), with a mean difference in BMI of 1.06 kg/m2 compared to 12 months postsurgery. Percent BMI loss was no longer significant after 24 months, and weight regain became significant within 48 months after surgery (p < 0.01). Among the patients who presented weight regain, a mean 8% increase was observed within 60 months compared to the lowest weight obtained at 18 months after surgery. The percentage of surgical failure was higher in the superobese group at all times studied, reaching 18.8% at 48 months after surgery. Weight regain was observed within 24 months after surgery in approximately 50% of patients. Both weight regain and surgical failure were higher in the superobese group. Studies in regard to metabolic and hormonal mechanisms underlying weight regain might elucidate the causes of this finding.

    Although health-enhancing weight reductions are associated with behavioural treatments initially, a trajectory towards full regain typically begins within 6-9 months. Women with obesity (body mass index = 30-40 kg m(-2) ) who lost at least 3% of their baseline weight within two trials of a new cognitive-behavioural treatment incorporating physical activity prior to changes in eating behaviours, and either regained ≥50% of that weight over 2 years (Regain group, n=32) or continued to lose weight (ContinuedLoss group, n = 34), were assessed from months 6 to 24 on changes in weight-loss behaviours and psychosocial predictors of those behaviours derived from established behavioural theories. For the Regain group, significant decreases in physical activity and fruit/vegetable intake during months 12-24, from both months 6 to 24 and 12 to 24 in eating- and physical activity-related self-regulation and from months 6 to 24 in eating-related self-efficacy (i.e. feelings of ability), were found. No significant behavioural or psychosocial changes were found over those times in the ContinuedLoss group. Changes in self-regulation and self-efficacy completely mediated the relationship between changes in fruit/vegetable intake and group (Regain vs. ContinuedLoss) (McFadden's R (2)  = 0.19 and 0.20, respectively), with self-regulation independently contributing to the explained variance. Changes over both months 6-24 and 12-24 in self-regulation significantly mediated the relationship between changes in physical activity and group membership (McFadden's R (2)  = 0.24 and 0.27, respectively). Findings suggested that approximately 6 months after treatment initiation would be a suitable time to intervene with some bolstering methods, while approximately 12 months post-initiation would be most applicable for others. © 2017 World Obesity Federation.

    The impact of regular exercise on energy balance, fuel utilization, and nutrient availability, during weight regain was studied in obese rats, which had lost 17% of their weight by a calorie-restricted, low-fat diet. Weight reduced rats were maintained for 6 wk with and without regular treadmill exercise (1 h/day, 6 days/wk, 15 m/min). In vivo tracers and indirect calorimetry were then used in combination to examine nutrient metabolism during weight maintenance (in energy balance) and during the first day of relapse when allowed to eat ad libitum (relapse). An additional group of relapsing, sedentary rats were provided just enough calories to create the same positive energy imbalance as the relapsing, exercised rats. Exercise attenuated the energy imbalance by 50%, reducing appetite and increasing energy requirements. Expenditure increased beyond the energetic cost of the exercise bout, as exercised rats expended more energy to store the same nutrient excess in sedentary rats with the matched energy imbalance. Compared with sedentary rats with the same energy imbalance, exercised rats exhibited the trafficking of dietary fat toward oxidation and away from storage in adipose tissue, as well as a higher net retention of fuel via de novo lipogenesis in adipose tissue. These metabolic changes in relapse were preceded by an increase in the skeletal muscle expression of genes involved in lipid uptake, mobilization, and oxidation. Our observations reveal a favorable shift in fuel utilization with regular exercise that increases the energetic cost of storing excess nutrients during relapse and alterations in circulating nutrients that may affect appetite. The attenuation of the biological drive to regain weight, involving both central and peripheral aspects of energy homeostasis, may explain, in part, the utility of regular exercise in preventing weight regain after weight loss.

    Dollo's law states that structures that are evolutionarily lost will not be regained. Recent phylogenetic studies have revealed several potential examples in which Dollo's law seems to be violated, where lost structures appear to have been regained over evolutionary time. However, these examples have recently been questioned and suggested to be methodological artifacts. In this article, I document a striking and incontrovertible phylogenetic example of the re-evolution of a lost, complex structure: mandibular teeth in the frog genus Gastrotheca. I use a time-calibrated phylogeny for 170 amphibian species to show that mandibular teeth were lost in the ancestor of modern frogs at least 230 million years ago (Mya) and have been regained in the last ∼ 5-17 My. I review recent studies on trait re-evolution and show that this long period of trait absence prior to re-acquisition is largely unprecedented. I also argue that there are several methodological issues that may cause trait re-evolution to be hardest to detect under those conditions when it is most likely to occur, leading to erroneous failures to reject Dollo's law. Finally, I discuss a mechanism that may facilitate trait re-evolution, and the evolution of mandibular teeth in frogs as an example of developmental constraint.

    This research note shares insights which resulted from a larger study into the ways in which the United Nations Educational, Scientific and Cultural Organization (UNESCO) - during 2010-2014 - used its position as coordinator of the post-Dakar Framework for Action (initiated at the World Education Forum held in 2000 and designed to reinvigorate the Education for All initiative) to help it regain some of the legitimacy it had lost in the preceding decades. The research study focused on the role of both the UNESCO Education for All Follow-up Unit and the production of the Global Monitoring Report (GMR) during the 2000s because they were at the heart of UNESCO's efforts to repair its image and renew its impact in one area of global governance, specifically in the global education policy field. The study's findings were based on an analysis of documents, archives and interviews ( n = 17) with key actors inside and outside UNESCO, including representatives of UNESCO's peer institutions.

    Weight regain after weight loss is a substantial challenge in obesity therapeutics. Dieting leads to significant adaptations in the homeostatic system that controls body weight, which promotes overeating and the relapse to obesity. In this review, we focus specifically on the adaptations in white adipose tissues that contribute to the biological drive to regain weight after weight loss. Weight loss leads to a reduction in size of adipocytes and this decline in size alters their metabolic and inflammatory characteristics in a manner that facilitates the clearance and storage of ingested energy. We present the hypothesis whereby the long-term signals reflecting stored energy and short-term signals reflecting nutrient availability are derived from the cellularity characteristics of adipose tissues. These signals are received and integrated in the hypothalamus and hindbrain and an energy gap between appetite and metabolic requirements emerges and promotes a positive energy imbalance and weight regain. In this paradigm, the cellularity and metabolic characteristics of adipose tissues after energy-restricted weight loss could explain the persistence of a biological drive to regain weight during both weight maintenance and the dynamic period of weight regain.

    Weight regain after bariatric surgery may be associated with behavioral, metabolic, or mechanical factors alone or in combination. The aim of this study was to investigate which factors are related to weight regain in the long-term after sleeve gastrectomy (SG). A retrospective case-control study with 40 patients undergoing SG (32 women, 8 men; age 42.9 ± 10.7 y; preoperative body mass index 35 ± 2.8 kg/m(2)), was performed. Patients were grouped according percentile->50% (cases) or weight regain (%WR cutoff: 25% of weight loss). Weight history, anthropometry, glucose, insulin, homeostasis model assessment-estimated insulin resistance (HOMA-IR), thyroid-stimulating hormone, resting energy expenditure, body composition, dietary survey, psychological test, and physical activity were recorded. Residual gastric capacity was estimated using a radiologic method. RESULTS (MEDIAN [P25-P75]): The evaluation was conducted 38.5 mo (34-41 mo) after SG. Percent weight regain ranged from 2.7% to 129.2% (25.4% [13-37.1]). Patients in the higher %WR group had a greater residual gastric volume (252.7 ± 108.4 versus 148.5 ± 25.3; P weight regain after SG was residual gastric volume. Additional prospective studies with larger numbers of patients are necessary to confirm our results. Copyright © 2016 Elsevier Inc. All rights reserved.

  17. Food restriction alters villi morphology in obese rats: gut mechanism for weight regain?

    Weight regain after a long-term weight-loss program is a greater problem in obesity treatment than is weight reduction. Hence, the gut may elevate the absorption rate and nutrient transportation remarkably during chronic food restriction. The extension of gut absorption may be one possible reason for weight regain. But there is little information about the mechanisms that regulate intestinal absorption during food restriction. In this study, we show that the surface absorptive areas of gut villi may be enlarged in the jejunum of rats maintained on a food restriction regimen compared with animals submitted to swimming or sedentary behavior. Our findings show that simply reducing the amount of food intake results in an increased appetite accompanied with obvious weight regain, and suggest that the resulting enlargement of villi surface areas plays a key role in the regain of weight reduction. These results bolster accumulating evidence that gut absorption may be a substantial mechanism for resistance of weight loss and enhancing the weight regain process.

  18. Strategies for Revitalizing Organizations: Regaining the Competitive Edge

    1987-01-01

    During the last decade, the United States has lost competitive stature in the world. Challenged daily by a technically sophisticated and vitalized global economy, industry and Government are examining quality and productivity initiatives with which to meet the foreign competitive challenge. At stake are our quality of life and our standard of living for the remainder of this century and beyond. Being competitive is an ongoing process, tuned to an awareness and understanding of the dynamics of the world marketplace and to the changing nature of the work environment. Solutions to America's quality and productivity problems do not exist independently within any organization or industry or at any given level of society. Success depends on commitment, partnership, meshing of goals and responsibilities, mutual respect and understanding, and a desire to be first. A change in organizational management culture is required. Traditional authoritarian management practices must give way to enlightened leadership initiatives that stress employee involvement and participation. There must be a lessening of adversarial relationships between management and labor and between industry and Government. Quality and productivity are understood to be the end result of an integrated process which begins with vigorous, committed leadership and ends with a satisfied customer. The essential elements in the revitalization process are organized in this report into seven strategies which represent the major findings of the Second NASA Symposium on Quality and Productivity. Each strategy is then broken down into its principal themes which are presented as recommendations. No one strategy can stand apart from any other; all are interrelated and work together.

    Objective: This study assessed if lower than predicted serum leptin concentrations seen during weight loss persisted during weight regain, with possible implications for weight control. Methods: 115 children were investigated during a 12-week weight loss program. 90 children completed the program....... Results: Children with the greatest increases in BMI standard deviation score (SDS) exhibited the largest leptin increments. The disproportionate reduction of leptin seen during weight loss recovered after weight loss. Leptin increases mirrored increases in BMI SDS during weight regain, and the leptin......-BMI SDS relationship seen during follow-up resembled the baseline leptin-BMI SDS relationship. Conclusion: Proportional increases of leptin and BMI SDS during weight regain suggests an intact leptin response during re-accumulation of fat. Following the pronounced reduction of leptin during weight loss...

    To evaluate laparoscopic re-sleeve gastrectomy as a treatment of weight regain after Sleeve. Laparoscopic sleeve gastrectomy is a common bariatric procedure. Weight regain after long-term follow-up is reported. Patients were considered for laparoscopic re-sleeve gastrectomy when we observed progressive weight regain and persistence of comorbidities associated with evidence of dilated gastric fundus and/or antrum on upper gastro-intestinal series. Follow-up visits were scheduled at 1, 3, 6 and 12 mo after surgery and every 6 mo thereafter. Measures of change from baseline at different times were analyzed with the paired samples t test. We observed progressive weight regain after sleeve in 11 of the 201 patients (5.4%) who had a mean follow-up of 21.1 ± 9.7 mo (range 6-57 mo). Three patients started to regain weight after 6 mo following Sleeve, 5 patients after 12 mo, 3 patients after 18 m. Re-sleeve gastrectomy was always performed by laparoscopy. The mean time of intervention was 55.8 ± 29.1 min. In all cases, neither intra-operative nor post-operative complications occurred. After 1 year follow-up we observed a significant (P weight loss (%EWL) increase (+31.0% ± 15.8%). An important reduction of antihypertensive drugs and hypoglycemic agents was observed after re-sleeve in those patients affected by hypertension and diabetes. Joint problems and sleep apnea syndrome improved in all 11 patients. Laparoscopic re-sleeve gastrectomy is a feasible and effective intervention to correct weight regain after sleeve.

    Initial successful weight loss is often followed by weight regain after the dietary intervention. Compared with lean people, cellular stress in adipose tissue is increased in obese subjects. However, the relation between cellular stress and the risk for weight regain after weight loss is unclear. Therefore, we determined the expression levels of stress proteins during weight loss and weight maintenance in relation to weight regain. In vivo findings were compared with results from in vitro cultured human Simpson-Golabi-Behmel syndrome (SGBS) adipocytes. In total, eighteen healthy subjects underwent an 8-week diet programme with a 10-month follow-up. Participants were categorised as weight maintainers or weight regainers (WR) depending on their weight changes during the intervention. Abdominal subcutaneous adipose tissue biopsies were obtained before and after the diet and after the follow-up. In vitro differentiated SGBS adipocytes were starved for 96 h with low (0·55 mm) glucose. Levels of stress proteins were determined by Western blotting. WR showed increased expressions of β-actin, calnexin, heat shock protein (HSP) 27, HSP60 and HSP70. Changes of β-actin, HSP27 and HSP70 are linked to HSP60, a proposed key factor in weight regain after weight loss. SGBS adipocytes showed increased levels of β-actin and HSP60 after 96 h of glucose restriction. The increased level of cellular stress proteins in the adipose tissue of WR probably resides in the adipocytes as shown by in vitro experiments. Cellular stress accumulated in adipose tissue during weight loss may be a risk factor for weight regain.

  3. Weight regain among women after metabolic and bariatric surgery: a qualitative study in Brazil

    2014-09-01

    Full Text Available INTRODUCTION: Due to the increased number of bariatric surgeries over the years, aspects contributing or hindering the achievement of outcomes, among them weight regain, have acquired increased significance. Psychological factors directly influence on this unwanted situation, but there are few studies and controversies about the degree of participation of these factors. We propose a qualitative investigation to analyze the meanings of weight regain after surgery among women and how these factors influence this outcome.METHOD: This study uses the clinical-qualitative method, by means of a semi-structured interview with open questions in an intentional sample, closed by saturation, with eight women who underwent surgery at the Bariatric Surgery Outpatient Clinic of Hospital das Clínicas, Universidade Estadual de Campinas (UNICAMP, in the state of São Paulo, Brazil.RESULTS: A feeling of defeat and failure emerges with weight regain, which contributes to social isolation; there is no regret, but gratitude for the surgery; among patients, there is a sense of feeling rejected greater than a rejection that actually exists.CONCLUSION: We found out the need for further qualitative studies that help the health team to better understand the dynamic psychological factors involved in the meaning of weight regain after bariatric surgery among women, in order to adopt appropriate conducts to deal with this problem.

    To monitor weight regain after therapy discontinuation in patients with migraine experiencing weight loss during topiramate (TPM) treatment. Patients with migraine without aura were enrolled in this observational prospective study. Weight, body mass index (BMI), waist circumference, systolic and diastolic blood pressure, plasma levels of total cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, triglycerides, leptin, and ghrelin, and homeostatic model assessment of insulin resistance (HOMA-IR) were evaluated before starting TPM (T1), at 3 (T2) and 6 (T3) months of treatment and 6 months after withdrawal of TPM (T4). Weight loss/regain was considered as a change of 5% of pre-TPM body weight. A total of 241 patients were analyzed. Of these, 87 (36%) patients experienced weight loss on TPM medication. During TPM therapy significant reductions in mean values of weight (pweight regain after therapy discontinuation. Loss of body weight is a reversible effect, which at 6 months after TPM discontinuation shows a clear trend to return to baseline values. HOMA-IR is the only predictive factor of weight regain.

    Numerous laboratory studies involving both animal and human models indicate that weight loss induces changes in leptin, ghrelin and insulin sensitivity, which work to promote weight regain. It is unclear, however, whether these biological changes serve as a biomarker for predicting weight regain in free-living humans in which biological, behavioral and environmental factors are likely at play. We identified 12 studies published between January 1995 and December 2011 that reported changes in leptin, ghrelin or insulin during intentional weight loss with a follow-up period to assess regain. Two of the nine studies examining leptin suggested that larger decreases were associated with greater regain, three studies found the opposite (smaller decreases were associated with greater regain), whereas four studies found no significant relationship; none of the studies supported the hypothesis that increases in ghrelin during weight loss were associated with regain. One study suggested that improvements in insulin resistance were associated with weight gain, but five subsequent studies reported no association. Changes in leptin, ghrelin or insulin sensitivity, taken alone, are not sufficient to predict weight regain following weight loss in free-living humans. In future studies, it is important to include a combination of physiological, behavioral and environmental variables in order to identify subgroups at greatest risk of weight regain.

Sand and gravel have been mined from alluvial flood-plain deposits less than 1 mi outside the roadless area; these deposits are likely to extend into the roadless area beneath a Holocene basalt flow that may be as much as 40 ft thick. An oil and gas lease application which includes the eastern portion of the roadless area is pending. Abundant basalt in the area can be crushed and used as aggregate, but similar deposits of volcanic cinders or sand and gravel in more favorable locations are available outside the roadless area closer to major markets. No indication of coal or geothermal energy resources was identified.

    We review our attempts to discover lost baryons at low redshift with ``X-ray forest'' of absorption lines from the warm-hot intergalactic medium. We discuss the best evidence to date along the Mrk 421 sightline. We then discuss the missing baryons in the Local Group and the significance of the z=0 absorption systems in X-ray spectra. We argue that the debate over the Galactic vs. extragalactic origin of the z=0 systems is premature as these systems likely contain both components. Observations with next generation X-ray missions such as Constellation-X and XEUS will be crucial to map out the warm-hot intergalactic medium.

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

    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.

    Acupuncture therapy for regaining consciousness activates soreness, numbness, distention, heaviness, radiating and moving, electric shock and ant climbing sensations at the specific acupoints in the stroke patients. Radiating and moving sensations are the summary of needling sensations such as soreness, numbness and twitching presenting during lifting and thrusting manipulation. These sensations are the essential factors of the therapeutic effect of regaining consciousness. Radiating sensation refers to the conduction along meridians and radiation of soreness and numbness. Moving sensation refers to the local muscular twitching at acupoints and the involuntary movement of limbs, joints and the distal. Acupuncture at the specific acupoints achieves radiating and moving sensations for promoting the circulation in meridians, regulating qi and mind and balancing yin and yang in stroke patients. This therapy was introduced in the paper in view of acupoint location, needle insertion and manipulation.

    Full Text Available Background: This study provides further evidence for improvement of memory by oral consumption of nutmeg. The present study was undertaken with an objective to study the effects of oral administration of nutmeg on memory boosting and regaining. Methods: Here we investigate the influence of oral intake of nutmeg on behavioral task performance by using T-maze and radial arm maze and physiological measures relative to a milk control group. Results: We have observed significant memory boosting and memory regaining effects of nutmeg when administered orally. This effect may be due to facilitation of acetylcholine activity by decreasing acetylcholinesterase activity of nutmeg. Hence we recommend further research in this area by investigating compound metabolism to optimize quantification of memory performance following nutmeg consumption.

  16. Hemorrhagic Fever with Renal Syndrome in the New, and Hantavirus Pulmonary Syndrome in the Old World: paradi(se)gm lost or regained?

    Since the first clinical description in 1994 of the so-called "Hantavirus Pulmonary Syndrome" (HPS) as a "newly recognized disease", hantavirus infections have always been characterized as presenting in two distinct syndromes, the so-called "Hemorrhagic Fever with Renal Syndrome" (HFRS) in the Old World, with the kidney as main target organ, in contrast to HPS in the New World, with the lung as main target organ. However, European literature mentions already since 1934 a mostly milder local HFRS form, aptly named "nephropathia epidemica" (NE), and caused by the prototype European hantavirus species Puumala virus (PUUV). Several NE reports dating from the 1980s and early 1990s described already non-cardiogenic HPS-like lung involvement, prior to any kidney involvement, and increasing evidence is now mounting that a considerable clinical overlap exists between HPS and HFRS. Moreover, growing immunologic insights point to common pathologic mechanisms, leading to capillary hyperpermeability, the cardinal feature of all hantavirus infections, both of the New and Old World. It is now perhaps time to reconsider the paradigm of two "different" syndromes caused by viruses of the same Hantavirus genus in the same Bunyaviridae family, and to agree on a common, more logical disease denomination, such as simply and briefly "Hantavirus fever".

    The failure of approximately 20 % of obese patients who undergo Roux-en-Y gastric bypass (RYGB) to maintain weight loss over the following 18-24 months is related to the surgical procedure, to the patient, or both. Although the underlying mechanisms are uncertain, one factor that has been postulated is the dilation of the gastrojejunal anastomosis. The objective was to evaluate the safety and efficacy of the serial use of argon plasma coagulation (APC) in reducing the diameter of the dilated gastrojejunal anastomosis and post-RYGB weight regain. We carried out a prospective, nonrandomized study of 30 patients, with no control or sham group, monitoring RYGB weight regain associated with dilation of the gastrojejunal anastomosis over a postoperative period of 18 months. Each patient underwent three sessions of APC in the anastomosis separated by 8 weeks, with a final endoscopic examination 8 weeks after the last session. There was a loss of 15.48 kg (range = 8.0-16.0 kg) of the 19.6 kg (range = 7.0-39.0 kg) of regained weight after RYGB and a reduction of 66.89 % in the final anastomotic diameter, with statistically significant reductions between each APC session. Previous body mass index significantly decreased up to the final examination, and the final weight was close to but not at the same level as the nadir. Our study indicates that the use of APC to treat weight regain after RYGB is a safe and effective procedure and promotes a reduction in gastrojejunal anastomosis, final weight, and BMI, with a low rate of complications.

    Polymorphisms in intron 1 of the 'fat mass and obesity-associated' (FTO) gene are associated with weight status. We hypothesized that the risk allele at a polymorphism in intron 1 of FTO is associated with weight regain after end of lifestyle intervention. We longitudinally analyzed the changes of weight status as BMI-SDS in 346 unrelated overweight children (mean age 10.6 ± 2.6 years, 45% male, mean BMI-SDS 2.39 ± 0.49) both at the end of a 1-year lifestyle intervention and 1 year after the end of this intervention. We genotyped the obesity risk SNP rs9939609 at FTO by ARMS-PCR. The children reduced their BMI-SDS (-0.29 ± 0.33; p weight regain 1 year after end of the intervention in multiple linear regression analyses adjusted for age, sex, pubertal stage, and baseline BMI-SDS (Bonferroni corrected p = 0.002).

    The recently discovered peptide irisin has been hypothesized to be a regulator of body metabolism. The objective of this work was to evaluate whether circulating human irisin levels are modulated by body size and changes in adiposity during an energy restriction treatment and the subsequent weight regain. A group of 94 obese patients (50 men, 44 women; 49.4 ± 9.4 years; BMI 35.6 ± 4.5 kg/m(2) ) participated in a weight loss program following an 8-week hypocaloric diet (-30% energy expenditure) with a weight maintenance follow-up. The patients were evaluated at 0, 8, and 24 weeks after starting treatment. In addition, 48 normal-weight subjects (16 men, 32 women; 35.71 ± 8.8 years; BMI 22.9 ± 2.2 kg/m(2) ) participated as controls. Plasma irisin, body weight, body composition, and hormones controlling energy homeostasis were measured. Irisin levels were higher in obese subjects (353.1 ± 18.6 ng/mL) than in those of normal-weight (198.4 ± 7.8 ng/mL; P ≤ 0.001) and were also higher in men (340.9 ± 20 ng/mL) than in women (267.6 ± 12 ng/mL; P weight, BMI, waist circumference, and fat mass, as measured by bioimpedance, but not with height or leptin levels. Interestingly, irisin levels paralleled body weight reduction after the dietary treatment (week 8) and again returned to the baseline levels at 24 weeks in those patients regaining the lost weight. Irisin strongly reflects body fat mass, suggesting that the irisin circulating levels are conditioned by adiposity level. Copyright © 2013 Wiley Periodicals, Inc.

    Bariatric surgery has been shown to be an effective treatment for obesity. Changes in energy expenditure, especially through diet-induced thermogenesis (DIT), have been identified as one of the mechanisms to explain this success. However, not all patients are able to maintain healthy postoperative weight loss. Therefore, a question arises: In the weight regain after bariatric surgery, are these changes in energy metabolism still active? To investigate if weight regain after Roux-en-Y gastric bypass (RYGB) surgery is associated with a lower diet-induced thermogenesis in the late postoperative period. A cross-sectional study with the participants chosen from among the patients from a private practice. This was a cross-sectional study where 3 groups of female patients were evaluated: (1) 20 patients with a RYGB postoperative time period of at least 2 years, who kept a healthy weight after surgery (loss of at least 50% of excess weight; Healthy group); (2) 19 patients with clinically severe obesity (BMI>40 kg/m(2), without co-morbidities and>35 kg/m(2), with co-morbidities; Pre group); (3) 18 patients who experienced weight regain after RYGB (Regain group). The 3 groups were submitted to indirect calorimetry to measure resting metabolic rate (RMR), respiratory quotient (RQ), and DIT. Immediately after the RMR measurement, a mixed meal of regular consistency was offered. Ten minutes after the food intake began, energy expenditure measurements were initiated continuing throughout the following 3 postprandial hours. Body composition was evaluated using multifrequency bioelectrical impedance. In subgroups of the studied population, glucose and insulin levels were measured at baseline and at 30, 60, 90, 120, and 180 minutes after feeding. The mean area under the curve (AUC) between the 3 groups and measurements at baseline were compared using the analysis of variance (ANOVA). The Healthy group had the highest weight adjusted RMR value compared with both the Pre and Regain

    This study was performed to examine whether changes in subcutaneous adipose tissue (SCAT) metabolism indices after weight loss were related to the magnitude of weight regain. Nine men and ten premenopausal women whose body mass index ranged from 30 to 42 kg/m(2), 35-48 years old, were studied before and after a 15-week weight loss program, as well as at a 17-22-month follow-up period. Although body composition was evaluated at all study periods, abdominal and femoral SCAT-lipoprotein lipase (LPL) and hormone-sensitive lipase (HSL) activities, and α2- and β-adrenoceptors (ARs) were measured before and after weight loss, exclusively. Although the SCAT-LPL activity did not change after weight loss in men, it tended to decrease in the femoral depot of women (p = 0.06). SCAT-HSL activity remained unchanged after weight reduction in men, while the post-weight loss lipase activity tended to be higher in both regions of women (p = 0.06). Although the post-weight loss number of β-ARs was higher irrespective of the fat depot (0.001 weight reduction, in men. Neither the α2- nor the β-AR density changed after weight reduction, in women. Abdominal SCAT-LPL activity after weight reduction was negatively related to weight regain indices, in women (-0.65 weight loss abdominal SCAT α2-AR density and the α2-/β-AR balance were positively associated with weight regain indices, in men (0.69 weight loss maintenance, in both genders.

    A variety of studies suggest that efficient treatments to induce short-term dietary success in obesity exist. However, sustained maintenance of reduced weight is rare as a large proportion of patients start to regain weight when treatment is discontinued. Thus, from a clinical perspective, it would be desirable to identify factors that counteract post-diet weight regain across longer time-scales. To address this question, we extended our previous work on neural impulse control mechanisms of short-term dietary success in obesity and now investigated the mechanisms counteracting long-term weight regain after a diet. Specifically, we measured neural impulse control during a delay discounting task with fMRI at two time points, i.e. the beginning ('T0') and the end ('T12') of a one-year follow-up interval after a 12-week diet. Then, we tested whether activity in the dorsolateral prefrontal cortex (DLPFC) at T0 and whether activity changes across the follow-up period (T0-T12) are linked to success in weight maintenance. The analyses conducted show that control-related DLPFC activity at T0 was coupled to the degree of success in weight maintenance. Consistently, also behavioral measures of control were linked to the degree of success in maintenance. A direct comparison of neural and behavioral control parameters for prognostic weight change modeling revealed that neural signals were more informative. Taken together, neural impulse control in the DLPFC measured with fMRI directly after a diet predicts real-world diet success in obese patients across extended time periods.

    Although weight cycling is frequent in obese patients, the adverse consequences on body composition and an increased propensity to weight gain remain controversial. We investigated the effect of intentional weight loss and spontaneous regain on fat distribution, the composition of lean mass and resting energy expenditure (REE). Weight regainers (≥ 30% of loss, n=27) and weight-stable subjects (within weight change, n=20) were selected from 103 overweight and obese subjects (body mass index 28-43 kg m(-2), 24-45 years) who passed a 13-week low-calorie diet intervention. REE and body composition (by densitometry and whole-body magnetic resonance imaging) were examined at baseline, after weight loss and at 6 months of follow-up. Mean weight loss was -12.3 ± 3.3 kg in weight-stable subjects and -9.0 ± 4.3 kg in weight regainers (PWeight regain was incomplete, accounting for 83 and 42% of weight loss in women and men. Regain in total fat and different adipose tissue depots was in proportion to weight regain except for a higher regain in adipose tissue of the extremities in women and a lower regain in extremity and visceral adipose tissue in men. In both genders, regain in skeletal muscle of the trunk lagged behind skeletal muscle regain at the extremities. In contrast to weight-stable subjects, weight regainers showed a reduced REE adjusted for changes in organ and tissue masses after weight loss (PWeight regain did not adversely affect body fat distribution. Weight loss-associated adaptations in REE may impair weight loss and contribute to weight regain.

    To develop statistical models for predicting weight loss and regain, we analyzed the phenotypic responses in an outpatient study of 60 obese subjects randomized to one of three 12-week interventions, diet (-600 kcal) alone, diet with exercise, and diet with sibutramine. This was followed by 12 weeks of observation. The best of the "baseline covariates" models was one that incorporated intervention group and baseline homeostasis model assessment-estimated insulin resistance (HOMA(IR)). It predicted week 12 weight change with R(2) of 0.38 and root mean square error (√MSE) of 2.92 kg. An alternative model incorporating baseline fat mass plus change in weight and HOMA(IR) at week 4 improved the prediction (R(2), 0.67, √MSE, 2.19 kg). We could not identify a satisfactory model to predict weight regain. We conclude that prediction of weight loss over 12 weeks is significantly improved when short-term weight change is incorporated into the model. This information could be utilized to forecast the success of a weight-loss program and to motivate and contribute to innovative designing of obesity trials.

    Extensive wildfires have affected the Russian region in the last decade. Scots pine forests (Pinus sylvestris L.) are widespread in central Siberia and fire occurrence is high in these forests, whose dominant fire regime is one of frequent surface fires. We studied post- fire succession of ground vegetation has been studied on nine experimental fires of varying severity (from 620 to 5220 kW/m) in middle taiga Scots pine forests of central Siberia (Russia). It proved from our study that all species of the succession process are present from initial stages. We did not find any trend of ground vegetation diversity with the time during 8 years after the fire. Our investigation showed that post- fire recovery of the ground vegetation is determined by initial forest type, fire severity and litter burning depth. Fire severity had a clear effect in initial succession in study area and it clearly had an impact on percentage cover, biomass and structure of ground vegetation. In a lesser degree the small shrubs are damaged during ground fires. The dominating species (Vaccinium vitis-idaea and V. myrtillus) regained the cover values above or close to 6—8 years. The post- fire biomass of ground vegetation 93—100% consists of species (Vaccinium vitis-idaea and V. myrtillus) that survived after the fire and increased in the cover with the time. In pine forests mosses and lichens suffer to a greater degree after ground fires. Lichen layer was completely lost after the fires of any severity. Decrease of mosses species diversity takes place after ground fires. The post- fire cover and species diversity of the green mosses were progressively lower with increasing the fire severity during the observation period. Maximum changes are discovered in the post- fire structure of plant microgroups after the high- severity fire which resulted in intensive invasion by the post- fire mosses (Polytrichum strictum and P. commune). There is a positive trend of green moss microgroups recovery

    Weight-loss maintenance after following an energy-restricted diet is a major problem that a number of studies are trying to characterise. The aim of the present study was to investigate the role of IL-6 -174G>C and PPAR-gamma2 Pro12Ala variants on weight regulation in obese subjects receiving a low-energy diet and at 1 year after the acute slimming period. Sixty-seven volunteers (age 34.7 (SD 7.0) years; BMI 35.8 (SD 4.8) kg/m(2)) were enrolled in a 10-week dietary intervention and were contacted again 1 year after the end of this period. Body composition was measured at three times during the study. Also, PPAR-gamma2 Pro12Ala and IL-6 -174G>C polymorphisms were analysed in the participants. No statistical differences were observed depending on the genetic variants at baseline for anthropometric variables, or after the intervention. However, the C allele of the -174G>C IL-6 gene polymorphism was more frequently observed (P=0.032) in subjects with successful weight maintenance (C polymorphism gives protection against regain of weight lost. Moreover, the presence of the Ala allele of the PPARgamma-2 together with the C allele strengthens this protection. These findings support a role for these polymorphisms on weight regulation and suggest a synergetic effect of both variants on weight maintenance after following a diet to lose weight.

    In this study, multivariate analyses was used to investigate factors associated with weight regain long after Roux-en-Y gastric bypass. This retrospective study comprised 80 patients (88.8% female) with at least 24 mo of postoperative time. Weight regain was defined as an increase of at least 10% of the lowest postoperative weight. The following data were collected: demographic characteristics, eating behavior, food intake, diet quality measured by the Healthy Eating Index, level of physical activity, follow-up visit attendance, anthropometric history, and postoperative time. Multivariate logistic regression generated a controlled analysis, followed by calculation of the odds ratio (OR). The mean postoperative time was 47.0 ± 18.0 mo. The mean pre- and postoperative body mass indexes were 49.8 ± 9.3 kg/m(2) and 33.6 ± 7.2 kg/m(2), respectively. Despite satisfactory postoperative weight loss, 23.7% of the patients regained weight. After controlling for confounders, only postoperative time (OR 1.08; P weight regain. Patients with long-term obesity and poor diet quality were at high risk of weight regain. These results suggest the need of nutritional monitoring during the late postoperative period, paying special attention to eating patterns. Copyright © 2016 Elsevier Inc. All rights reserved.

    The role of thyroid hormones in diet-induced weight loss and subsequent weight regain is largely unknown. To examine the associations between thyroid hormones and changes in body weight and resting metabolic rate (RMR) in a diet-induced weight loss setting. Data analysis was conducted among 569 overweight and obese participants aged 30-70 years with normal thyroid function participating in the 2-year Prevention of Obesity Using Novel Dietary Strategies (POUNDS) LOST randomized clinical trial. Changes in body weight and RMR were assessed during the 2-year intervention. Thyroid hormones (free triiodothyronine (T3), free thyroxine (T4), total T3, total T4 and thyroid-stimulating hormone (TSH)), anthropometric measurements and biochemical parameters were assessed at baseline, 6 months and 24 months. Participants lost an average of 6.6 kg of body weight during the first 6 months and subsequently regained an average of 2.7 kg of body weight over the remaining period from 6 to 24 months. Baseline free T3 and total T3 were positively associated, whereas free T4 was inversely associated, with baseline body weight, body mass index and RMR. Total T4 and TSH were not associated with these parameters. Higher baseline free T3 and free T4 levels were significantly associated with a greater weight loss during the first 6 months (Pweight. Comparing extreme tertiles, the multivariate-adjusted weight loss±s.e. was -3.87±0.9 vs -5.39±0.9 kg for free T3 (Ptrend=0.02) and -4.09±0.9 vs -5.88±0.9 kg for free T4 (Ptrend=0.004). The thyroid hormones did not predict weight regain in 6-24 months. A similar pattern of associations was also observed between baseline thyroid hormones and changes in RMR. In addition, changes in free T3 and total T3 levels were positively associated with changes in body weight, RMR, body fat mass, blood pressure, glucose, insulin, triglycerides and leptin at 6 months and 24 months (all Pweight loss setting, higher baseline free T3 and free T4

    Successful weight maintenance following weight loss is challenging for many people. Identifying predictors of longer-term success will help target clinical resources more effectively. To date, focus has been predominantly on the identification of predictors of weight loss. The goal of the current study was to determine if changes in anthropometric and clinical parameters during acute weight loss are associated with subsequent weight regain. The study consisted of an 8-week low calorie diet (LCD) followed by a 6-month weight maintenance phase. Anthropometric and clinical parameters were analyzed before and after the LCD in the 285 participants (112 men, 173 women) who regained weight during the weight maintenance phase. Mixed model ANOVA, Spearman correlation, and linear regression were used to study the relationships between clinical measurements and weight regain. Gender differences were observed for body weight and several clinical parameters at both baseline and during the LCD-induced weight loss phase. LCD-induced changes in BMI (Spearman's ρ = 0.22, p = 0.0002) were inversely associated with weight regain in both men and women. LCD-induced changes in fasting insulin (ρ = 0.18, p = 0.0043) and HOMA-IR (ρ = 0.19, p = 0.0023) were also associated independently with weight regain in both genders. The aforementioned associations remained statistically significant in regression models taking account of variables known to independently influence body weight. LCD-induced changes in BMI, fasting insulin, and HOMA-IR are inversely associated with weight regain in the 6-month period following weight loss.

    Weight loss dieting remains the treatment of choice for the vast majority of obese individuals, despite the limited long-term success of behavioral weight loss interventions. The reasons for the near universal unsustainability of behavioral weight loss in [formerly] obese individuals have not been fully elucidated, relegating researchers to making educated guesses about how to improve obesity treatment, as opposed to developing interventions targeting the causes of weight regain. This article discusses research on several factors that may contribute to weight regain following weight loss achieved through behavioral interventions, including adipose cellularity, endocrine function, energy metabolism, neural responsivity, and addiction-like neural mechanisms. All of these mechanisms are engaged prior to weight loss, suggesting that these so called "anti-starvation" mechanisms are activated via reductions in energy intake, rather than depletion of energy stores. Evidence suggests that these mechanisms are not necessarily part of a homeostatic feedback system designed to regulate body weight, or even anti-starvation mechanisms per se. Although they may have evolved to prevent starvation, they appear to be more accurately described as anti-weight loss mechanisms, engaged with caloric restriction irrespective of the adequacy of energy stores. It is hypothesized that these factors may combine to create a biological disposition that fosters the maintenance of an elevated body weight and works to restore the highest sustained body weight, thus precluding the long-term success of behavioral weight loss. It may be necessary to develop interventions that attenuate these biological mechanisms in order to achieve long-term weight reduction in obese individuals. © 2013 Elsevier Inc. All rights reserved.

  19. Pouch Reshaping for Significant Weight Regain after Roux-en-Y Gastric Bypass.

    Significant weight regain after Roux-en-Y gastric bypass (RYGB) occurs in around 20 % of patients in the long term. Anatomical reasons include dilatation of the gastric pouch and/or the pouch-jejunal anastomosis, leading to loss of restriction. Pouch reshaping (PR) aims at reestablishing restriction with a subsequent feeling of satiety. This study reports the outcome of PR embedded in a multidisciplinary treatment pathway. Twenty-six patients after PR for weight regain >30 % following RYGB in a university hospital between October 2010 and March 2016 were analyzed. Excluded were patients with PR for gastro-gastric fistulae, hypoglycemia, candy cane syndrome, and concomitant alteration of limb lengths. PR consisted in laparoscopic lateral resection of the gastric pouch, the anastomosis and the proximal 5 cm of the alimentary limb over a 32F bougie. Median follow-up after PR was 48 months (range 24-60). Median BMI at PR was 39.1 kg/m(2) (32.7-59.1). Median operation time was 85 min (25-190), and median length of stay was 3 days (1-35). Minor complications (grade ≤ 2) occurred in seven (27 %) patients and major complications (grade ≥ 3) in four patients (15 %). Nadir BMI and %EBMIL after PR were 32.9 kg/m(2) and 43.3 %, reached after a median of 12 months (3-48). Comorbidities were resolved in 81 %. After 48 months, median BMI was 33.8 kg/m(2) (20.4-49.2) and %EBMIL was 61.4 (39.1-121.2). Used selectively in a multidisciplinary treatment pathway, PR leads to prolonged weight stabilization around the previous nadir. However, its associated perioperative morbidity must not be disregarded.

    Treatment in intensive care units (ICUs) often results in swallowing dysfunction. Recent longitudinal studies have described the recovery of critically ill people, but we are not aware of studies of the recovery of swallowing function in patients with ICU-acquired muscle weakness. This paper aims to describe the time course of regaining water swallowing function in patients with ICU-acquired weakness in the post-acute phase and to describe the risks of regaining water swallowing function and the risk factors involved. This cohort study included patients with ICU-acquired muscle weakness in our post-acute department, who were unable to swallow. We monitored the process of regaining water swallowing function using the 3-ounce water swallowing test. We included 108 patients with ICU-acquired muscle weakness. Water swallowing function was regained after a median of 12 days (interquartile range =17) from inclusion in the study and after a median of 59 days (interquartile range= 36) from the onset of the primary illness. Our multivariate Cox Proportional Hazard model yielded two main risk factors for regaining water swallowing function: the number of medical tubes such as catheters at admission to the post-acute department (adjusted hazard ratio [HR] = 1.282; 95% confidence interval [CI]: 1.099-1.495) and the time until weaning from the respirator in days (adjusted HR =1.02 per day; 95%CI: 0.998 to 1.008). We describe a time course for regaining water swallowing function based on daily tests in the post-acute phase of critically ill patients. Risk factors associated with regaining water swallowing function in rehabilitation are the number of medical tubes and the duration of weaning from the respirator. Implications for rehabilitation Little guidance is available for the management of swallowing dysfunction in the rehabilitation of critically ill patients with intensive-care-units acquired muscle weakness. There is a time dependent pattern of recovery from

    Weight regain 24 months after Roux-en-Y gastric bypass (RYGB) and low protein intake in patients without protein supplementation can favor fat-free mass loss and reduce resting energy expenditure (REE). We aimed to assess REE and its association with the body composition of women with weight regain and no protein supplementation in the late postoperative period of RYGB. We determined the body mass index (BMI), REE by indirect calorimetry, body composition by tetrapolar bioelectrical impedance analysis, and energy intake by two 24-h recalls of 34 patients with at least 5 % of weight regain and no protein supplementation. The software SPSS v.17 analyzed the data calculating measures of central tendency and dispersion and using Pearson's correlation to test the association between the variables and the multivariate linear regression model at a p weight regain (r = 0.39; p = 0.023). The mean percentages of fat and fat-free masses were 45.1 ± 8.3 % and 54.3 ± 8.1 %, respectively. The mean REE was 1424.7 ± 187.2 kcal (14 kcal/kg of the current weight), mean energy intake was 1258.6 ± 454.3 kcal, and mean protein intake was 0.9 g/kg of the ideal weight ± 0.3. Fat-free mass was positively associated with REE regardless of protein intake and postoperative period. Female bariatric patients with weight regain and no protein supplementation lose fat-free mass, lowering their REE. Health practices that promote maintenance of BMI and body composition may lead to improved outcomes of bariatric surgery.

    To investigate the effect of rate of weight loss, with similar total weight loss, on weight regain in individuals with overweight and obesity. Fifty-seven participants (BMI: 28-35 kg/m(2) ) underwent a dietary intervention (DI). They were randomized to a low-calorie diet (LCD; 1250 kcal/day) for 12 weeks (slow weight loss) or a very-low-calorie diet (VLCD; 500 kcal/day) for 5 weeks (rapid weight loss) (weight loss (WL) period) followed by a 4-week weight-stable (WS) period and 9 months follow-up. Body weight and body composition (BodPod) were determined at study start and after each period. Weight change was similar in both groups after WL (LCD: -8.2 kg and VLCD: -9.0 kg, P = 0.24). Weight regain after follow-up was not significantly different between groups (LCD: 4.2 kg and VLCD: 4.5 kg, P = 0.73). Percentage fat-free mass loss (%FFML) was higher in the VLCD-group compared to the LCD-group after DI (8.8% and 1.3%, respectively, P = 0.034) and was associated with weight regain during follow-up in the whole group (r = 0.325, P = 0.018). The present study showed that, with similar total weight loss, rate of weight loss did not affect weight regain. However, %FFML after DI was associated with weight regain. © 2016 The Obesity Society.

    Carolina bays are shallow wetland depressions found only on the Atlantic Coastal Plain. Although these isolated interstream wetlands support many types of communities, they share the common features of having a sandy margin, a fluctuating water level, an elliptical shape, and a northwest to southeast orientation. Lost Lake, an 11.3 hectare Carolina bay, was ditched and drained for agricultural production before establishment of the Savannah River Site in 1950. Later it received overflow from a seepage basin containing a variety of chemicals, primarily solvents and some heavy metals. In 1990 a plan was developed for the restoration of Lost Lake, and restoration activities were complete by mid-1991. Lost Lake is the first known project designed for the restoration and recovery of a Carolina bay. The bay was divided into eight soil treatment zones, allowing four treatments in duplicate. Each of the eight zones was planted with eight species of native wetland plants. Recolonization of the bay by amphibians and reptiles is being evaluated by using drift fences with pitfall traps and coverboard arrays in each of the treatment zones. Additional drift fences in five upland habitats were also established. Hoop turtle traps, funnel minnow traps, and dip nets were utilized for aquatic sampling. The presence of 43 species common to the region has been documented at Lost Lake. More than one-third of these species show evidence of breeding populations being established. Three species found prior to the restoration activity and a number of species common to undisturbed Carolina bays were not encountered. Colonization by additional species is anticipated as the wetland undergoes further succession.

    Long before GPS, Google Earth, and global transit, humans traveled vast distances using only environmental clues and simple instruments. John Huth asks what is lost when modern technology substitutes for our innate capacity to find our way. Encyclopedic in breadth, weaving together astronomy, meteorology, oceanography, and ethnography, The Lost Art of Finding Our Way puts us in the shoes, ships, and sleds of early navigators for whom paying close attention to the environment around them was, quite literally, a matter of life and death. Haunted by the fate of two young kayakers lost in a fogbank off Nantucket, Huth shows us how to navigate using natural phenomena—the way the Vikings used the sunstone to detect polarization of sunlight, and Arab traders learned to sail into the wind, and Pacific Islanders used underwater lightning and “read” waves to guide their explorations. Huth reminds us that we are all navigators capable of learning techniques ranging from the simplest to the most sophisticated skil...

  14. How business schools lost their way.

    Science.gov (United States)

    Bennis, Warren G; O'Toole, James

    2005-05-01

    Business schools are facing intense criticism for failing to impart useful skills, failing to prepare leaders, failing to instill norms of ethical behavior--and even failing to lead graduates to good corporate jobs. These criticisms come not just from students, employers, and the media but also from deans of some of America's most prestigious B schools. The root cause oftoday's crisis in management education, assert Warren G. Bennis and James O'Toole, is that business schools have adopted an inappropriate--and ultimately self-defeating--model of academic excellence. Instead of measuring themselves in terms of the competence of their graduates, or by how well their faculty members understand important drivers of business performance, they assess themselves almost solely by the rigor of their scientific research. This scientific model is predicated on the faulty assumption that business is an academic discipline like chemistry or geology when, in fact, business is a profession and business schools are professional schools--or should be. Business school deans may claim that their schools remain focused on practice, but they nevertheless hire and promote research-oriented professors who haven't spent time working in companies and are more comfortable teaching methodology than messy, multidisciplinary issues--the very stuff of management. The authors don't advocate a return to the days when business schools were glorified trade schools. But to regain relevancy, they say, business schools must rediscover the practice of business and find a way to balance the dual mission of educating practitioners and creating knowledge through research.

  15. Lost City and the Search For Life

    Science.gov (United States)

    Kelley, D. S.

    2014-12-01

    Since their discovery in 1979, high-temperature hot springs fueled by submarine volcanoes have served as models in the search for life elsewhere in the solar system. The early recognition of hot microbial biospheres associated with active volcanism along global mid-ocean ridges fundamentally shifted concepts of how planets and life co-evolve. These metal-rich, acidic systems were thought to represent the most extreme conditions on Earth, hosting novel life based on chemosynthesis. In 2000, this paradigm was profoundly impacted by the discovery of the Lost City hydrothermal field, characterized by conditions never before seen. Here, 60 m-tall limestone chimneys vent pH 10-11, metal-poor, 90°C fluids rich in hydrogen and abiotically-produced methane and formate. The fluid chemistry is driven, not by volcanic heat, but by fluid-rock reactions in underlying ultramafic basement at up to ~ 200°C. These peridotite-hosted biotopes differ significantly from volcanic-hosted vent systems in which carbon dioxide is a dominant volatile species. Instead, serpentinzation reactions yield high hydrogen and low molecular-weight hydrocarbons that result in energy-rich habitats with cell concentrations that reach 109cells/gram carbonate. The absence of volcanism, and on-going serpentinization reactions result in a remarkably stable system with venting active for >150,000 years. With the discovery of Lost City, it is clear that high temperature volcanic activity is not a prerequisite for life. Exothermic serpentinization reactions occur under a wide-range of temperatures and can result in up to a 40% volume of expansion, which may both close and open fractures. Hence, Lost City may serve as a model in the search for life on other planets and moons with rocky, undifferentiated terranes and overlying oceans. Within such systems, interior cooling, coupled with tidally-induced heating may induce hydrothermal flow, and perhaps life-sustaining environments in the absence of volcanism.

    PMMA polymer has been grafted onto wool fabric by two methods of grafting preirradiation method and chemical initiation using KMnO{sub 4}/H{sub 2}SO{sub 4} system. The grafted wool showed an enhancement in dyeability towards some basic dyes differing in size and chemical structure. Preirradiated grafted wool exhibited a relatively higher dyeing affinity than that prepared by the chemical method. Graft yield of up to 26% of PPMA did not have a noticeable effect on the moisture regain of wool fabric. Further increase in graft yield was found to cause a slight reduction in moisture regain. The tensile strength was reduced by the graft process, but elongation at break was not affects. (author).

    The paper presents a new hidden data insertion procedure based on estimated probability of the remaining time of the call for steganographic method called LACK (Lost Audio PaCKets steganography). LACK provides hidden communication for real-time services like Voice over IP. The analytical results presented in this paper concern the influence of LACK's hidden data insertion procedures on the method's impact on quality of voice transmission and its resistance to steganalysis. The proposed hidden data insertion procedure is also compared to previous steganogram insertion approach based on estimated remaining average call duration.

    Background Wavelet index (WLI) is a new parameter for monitoring depth of anesthesia based on Wavelet analysis.We observed the change of WLI and bispectral index (BIS) in patients regain of consciousness (ROC) in the absence of frontalis electromyographic (EMG) interference. The aim of this study was to compare the ability of WLI and BIS for reflecting ROC in patients undergone surgery.Methods Twelve patients who were scheduled for maxillofacial surgeries were enrolled in the study. BIS and WLI values were monitored continually. After being given midazolam and remifentanil, patients were asked to squeeze the investigator's hand ever 30 seconds. Patients were continuously given propofol until loss of consciousness (LOC1).Tunstall's isolated forearm technique was used to test the surgical consciousness in patients. After total muscle relaxation,endotracheal intubations were performed, and the patients were connected to a ventilator. Then, propofol was withdrawn until the patients showed regain of consciousness (ROC1) and an awareness reaction. After the command test, patients were readministered with propofol until loss of consciousness (LOC2). After surgery, all of the sedatives were withdrawn,and the patients were let to regain consciousness (ROC2).Results The BIS values of twelve patients at ROC1 after using muscle relaxant were much lower than those at LOC1 and ROC2 without using muscle relaxant, showing statistical significance (P <0.05). Meanwhile, the WLI values of twelve patients at ROC1 after using muscle relaxant were much higher than those at LOC1 and equal to ROC2 without using muscle relaxant, showing statistical significances (P <0.05) between ROC1 and LOC1.Conclusions This study showed that under muscle relaxation or facial paralysis, when there is no EMG signal, BIS can not accurately reflect regain of consciousness in surgical patients, but WLI can reflect it accurately. So WLI may have advantages for reflecting state of consciousness in surgical

  19. Resistant starch and exercise independently attenuate weight regain on a high fat diet in a rat model of obesity

    Science.gov (United States)

    2011-01-01

    Background Long-term weight reduction remains elusive for many obese individuals. Resistant starch (RS) and exercise may be useful for weight maintenance. The effects of RS, with or without exercise, on weight regain was examined during relapse to obesity on a high carbohydrate, high fat (HC/HF) diet. Methods Obesity-prone rats were fed ad libitum for 16 weeks then weight reduced on a low fat diet to induce a 17% body weight loss (weight reduced rats). Weight reduced rats were maintained on an energy-restricted low fat diet for 18 weeks, with or without a daily bout of treadmill exercise. Rats were then allowed free access to HC/HF diet containing low (0.3%) or high (5.9%) levels of RS. Weight regain, energy balance, body composition, adipocyte cellularity, and fuel utilization were monitored as rats relapsed to obesity and surpassed their original, obese weight. Results Both RS and exercise independently attenuated weight regain by reducing the energy gap between the drive to eat and suppressed energy requirements. Exercise attenuated the deposition of lean mass during relapse, whereas its combination with RS sustained lean mass accrual as body weight returned. Early in relapse, RS lowered insulin levels and reduced the deposition of fat in subcutaneous adipose tissue. Exercise cessation at five weeks of relapse led to increased weight gain, body fat, subcutaneous adipocytes, and decreased lean mass; all detrimental consequences to overall metabolic health. Conclusions These data are the first to show the complimentary effects of dietary RS and regular exercise in countering the metabolic drive to regain weight following weight loss and suggest that exercise cessation, in the context of relapse on a HC/HF diet, may have dire metabolic consequences.

To date, focus has been predominantly on the identification of predictors of weight loss. The goal of the current...... study was to determine if changes in anthropometric and clinical parameters during acute weight loss are associated with subsequent weight regain....

    Full Text Available Abstract Background Long-term weight reduction remains elusive for many obese individuals. Resistant starch (RS and exercise may be useful for weight maintenance. The effects of RS, with or without exercise, on weight regain was examined during relapse to obesity on a high carbohydrate, high fat (HC/HF diet. Methods Obesity-prone rats were fed ad libitum for 16 weeks then weight reduced on a low fat diet to induce a 17% body weight loss (weight reduced rats. Weight reduced rats were maintained on an energy-restricted low fat diet for 18 weeks, with or without a daily bout of treadmill exercise. Rats were then allowed free access to HC/HF diet containing low (0.3% or high (5.9% levels of RS. Weight regain, energy balance, body composition, adipocyte cellularity, and fuel utilization were monitored as rats relapsed to obesity and surpassed their original, obese weight. Results Both RS and exercise independently attenuated weight regain by reducing the energy gap between the drive to eat and suppressed energy requirements. Exercise attenuated the deposition of lean mass during relapse, whereas its combination with RS sustained lean mass accrual as body weight returned. Early in relapse, RS lowered insulin levels and reduced the deposition of fat in subcutaneous adipose tissue. Exercise cessation at five weeks of relapse led to increased weight gain, body fat, subcutaneous adipocytes, and decreased lean mass; all detrimental consequences to overall metabolic health. Conclusions These data are the first to show the complimentary effects of dietary RS and regular exercise in countering the metabolic drive to regain weight following weight loss and suggest that exercise cessation, in the context of relapse on a HC/HF diet, may have dire metabolic consequences.

    Differentiated somatic cells can be reprogrammed into pluripotent stem cells by transduction of exogenous reprogramming factors. After induced pluripotent stem (iPS) cells are established, exogenous genes are silenced. In the pluripotent state, retroviral genes integrated in the host genome are kept inactive through epigenetic transcriptional regulation. In this study, we tried to determine whether exogenous genes remain silenced or are reactivated upon loss of pluripotency or on differentiation using an in vitro system. We induced differentiation of iPS cells into neural stem cells (NSCs) in vitro; the NSCs appeared morphologically indistinguishable from brain-derived NSCs and stained positive for the NSC markers Nestin and Sox2. These iPS cell-derived NSCs (iPS-NSCs) were also capable of differentiating into all three neural subtypes. Interestingly, iPS-NSCs spontaneously formed aggregates on long-term culture and showed reactivation of the Oct4-GFP marker, which was followed by the formation of embryonic stem cell-like colonies. The spontaneously reverted green fluorescent protein (GFP)-positive (iPS-NSC-GFP(+) ) cells expressed high levels of pluripotency markers (Oct4 and Nanog) and formed germline chimeras, indicating that iPS-NSC-GFP(+) cells had the same pluripotency as the original iPS cells. The reactivation of silenced exogenous genes was tightly correlated with the downregulation of DNA methyltransferases (Dnmts) during differentiation of iPS cells. This phenomenon was not observed in doxycycline-inducible iPS cells, where the reactivation of exogenous genes could be induced only by doxycycline treatment. These results indicate that pluripotency can be regained through reactivation of exogenous genes, which is associated with dynamic change of Dnmt levels during differentiation of iPS cells.

  3. Life interrupted and life regained? Coping with stroke at a young age

    Full Text Available Stroke is a leading cause of disability across the developed world, affecting an increasing number of younger people. In this article, we seek to understand the experience of stroke as a disabling life situation among young people and the strategies that they use to recover and cope. Directed content analysis was conducted from interviews with 17 community-dwelling stroke survivors aged 55 years and younger across the United Kingdom. The sample was drawn from a larger maximum variation sample of stroke survivors. Using the sociological concepts of biographical disruption and biographical repair as a guide, excerpts from the interviews pertaining to aspects of the patients’ life that were interrupted, in addition to how they coped with the changes, were selected and analysed. All individuals described an “altered sense of self,” a theme that included loss of identity, family disruption, and/or loss of valued activities. Individuals sought to adapt their sense of self by seeking external support, by restoring normality, and/or through positive reflection. Despite the adapted self that emerged, most individuals continued to experience impairments. While young stroke survivors adapt to their illness over time, they continue to experience impairments and disruptions in their personal and work lives. A holistic model of rehabilitation that helps individuals regain the capacity for everyday activities related to work, family life, and leisure can begin to address the emotional ramifications of diseases such as stroke, restore wellness, and work towards minimizing the burden felt by family caregivers and children.

    Comet D/1770 L1 (Lexell) made the closest observed pass by a comet to the Earth at approximately 0.015 AU on 1 July 1770. A naked-eye object observed by many astronomers of the time, it was subsequently lost: the best contemporary estimates had it removed from its 1770 orbit by Jupiter in 1779 and sent to the outer Solar System.Near-Earth asteroid 2010 JL33 has an orbit similar to that followed by Lexell's comet during its observed apparition. However, this NEA's nominal orbit, which is well-known on the basis of a decade-long arc which includes radar observations, does not approach the Earth at the correct time to be Lexell's comet. That is, unless modest non-gravitational forces are applied, in which case the famous near-miss can be reproduced.Modern measurements of 2010 JL33 together with those Lexell's comet made in the 18th century -which include motion exceeding 40 degrees per day on the sky at closest approach- provide exquisite constraints on the dynamical processes at work, cometary, Yarkovsky or other. I will discuss the implications of and the conditions required for asteroid 2010 JL33 to be, in fact, long-lost comet Lexell.

    Although obesity causes many adverse health consequences, modest weight loss reduces the incidence. There are effective interventions that help people to lose weight but weight regain is common and long term maintenance remains a critical challenge. As a high proportion of the population of most high and middle income countries are overweight, there are many people who would benefit from weight loss and its maintenance. Therefore, we need to find effective low cost scalable interventions to help people achieve this. One such intervention that has shown promise is regular self-weighing, to check progress against a target, however there is no trial that has tested this using a randomised controlled design (RCT). The aim of this RCT is to evaluate the effectiveness and cost effectiveness of a brief behavioural intervention delivered by non-specialist staff to promote regular self-weighing to prevent weight regain after intentional weight loss. A randomised trial of 560 adults who have lost ≥ 5 % of their initial body weight through a 12 week weight loss programme. The comparator group receive a weight maintenance leaflet, a diagram representing healthy diet composition, and a list of websites for weight control. The intervention group receive the same plus minimally trained telephonists will ask participants to set a weight target and encourage them to weigh themselves daily, and provide support materials such as a weight record card. The primary outcome is the difference between groups in weight change from baseline to 12 months. If effective, this study will provide public health agencies with a simple, low cost maintenance intervention that could be implemented immediately. ISRCTN52341938 Date Registered: 31/03/2014.

    Systematic, thematic, narrative review of qualitative literature. To systematically review qualitative research that explores the impact of spinal cord injury (SCI) on the gendered experience of men with SCI. A systematic search of databases and hand search of relevant journals to provide a thematic narrative review of articles, providing sufficient depth of information, relevant participant quotes and phenomenological insight into the gendered experience of men with SCI. Identified studies are summarised and common themes extracted and discussed in relation to relevant literature on masculinity, disability and health. Eight papers, representing four separate studies met the review criteria for relevance and rigour. Three broad, overlapping themes describing the gendered experience of men with SCI were identified: 'lost masculinity', outlining the impact of SCI on traditional masculine identity, 'fighting back', describing the battle to regain and reclaim masculinity and integrate disability into a revised identity and 'beyond hegemony', referring to possibilities beyond adherence to traditional masculine scripts. This review demonstrates a lack of explicit focus on men as gendered beings within the available qualitative literature. The findings are consistent with the limited quantitative data, which indicates that grappling with altered gendered identity is a central feature of life for men with SCI. Masculine identity emerges in this review as vulnerable to the impact of SCI, and given the strong links identified between masculinity, rehabilitation and health, as an aspect of experience that warrants more attention than it has received.

    Grounded theory is a popular research approach in health care and the social sciences. This article provides a description of grounded theory methodology and its key components, using examples from published studies to demonstrate practical application. It aims to demystify grounded theory for novice nurse researchers, by explaining what it is, when to use it, why they would want to use it and how to use it. It should enable nurse researchers to decide if grounded theory is an appropriate approach for their research, and to determine the quality of any grounded theory research they read.

  11. Sociology: a lost connection in social psychology.

    2009-11-01

    For the first half of the 20th century, sociology was one of the closest allies of social psychology. Over the past four decades, however, the connection with sociology has weakened, whereas new connections with neighboring disciplines (e.g., biology, economics, political science) have formed. Along the way, the sociological perspective has been largely lost in mainstream social psychology in the United States. Most social psychologists today are not concerned with collective phenomena and do not investigate social structural factors (e.g., residential mobility, socioeconomic status, dominant religion, political systems). Even when the social structural factors are included in the analysis, psychologists typically treat them as individual difference variables. Sociologist C. Wright Mills famously promoted sociological imagination, or the ability to see distal yet important social forces operating in a larger societal context. By comparing sociological perspectives to psychological perspectives, this article highlights the insights that the sociological perspective and sociological imagination can bring to social psychology.

    Lost Causes in and Beyond Physics deals with a selection of research topics mostly from theoretical physics that have been shown to be a dead-end or continue at least to be highly controversial. Nevertheless, whether it is about Bohmian mechanics, physics from Fisher information or the quantum theory of the brain, small but dedicated research communities continue to work on these issues. R.F. Streater, renowned mathematical physicist and co-author of the famous book "PCT, Spin and Statistics, and all that", in a series of essays describes the work and struggle of these research commnities, as well as the chances of any breakthrough in these areas. This book is written as both an entertainment and serious study and should be accessible to anyone with a background in theoretical physics and mathematics.

    It is estimated that 4.9 million liters of petroleum are spilled into U.S. waters from vessels and pipelines in a typical year. Oil spill may be as huge as of 8 million barrels (The Persian Gulf oil spill of 1991). Oil-water separation processes using polymeric or inorganic membranes have been proposed as effective and cost competitive technologies but in present the commercial use of membrane in treatment of spilled oil is currently limited by their low efficiency as well as high capital and operating cost. Indian hair-market is a billion-dollar industry yearly exporting thousands of tones of thick and dark hairs. Hairs contain keratin, a family of fibrous structural proteins been proved to adsorb oils. Laboratory results conclude that one gram of human hair can selectively adsorb about 15.5301 grams of crude oil over water, following Frendlich's isotherm. We seek hair mats made up of hairs of size ≤5 inches, costing 37/ton from selected parts of Indian hair market. With a known adsorbing efficiency of 95% towards crude oil, an estimated desorption efficiency of 70% oil worth 0.8M per year can be regained in crude form from U.S. waters only. To ensure solid waste management of hairs, hair mats left with 30% of adsorbed oil can be utilized in the cultivation of oyster mushrooms, a 20-34/kg crop that grows best in 20-25°C ,80-90% relative humidity and oily conditions. This will reduce the growing period of crop ensuring yearly profit of $6.06M in U.S. only engaging variety of stakeholders over borders. Results thus obtained in this study present an economic, safer and sustainable technique to minimize oil loss due to oil spill in waters further ensuring a low labor-low cost technique of waste management that enhances the growth of an in-demand crop.

    2008-01-01

    Grounded cognition rejects traditional views that cognition is computation on amodal symbols in a modular system, independent of the brain's modal systems for perception, action, and introspection. Instead, grounded cognition proposes that modal simulations, bodily states, and situated action underlie cognition. Accumulating behavioral and neural evidence supporting this view is reviewed from research on perception, memory, knowledge, language, thought, social cognition, and development. Theories of grounded cognition are also reviewed, as are origins of the area and common misperceptions of it. Theoretical, empirical, and methodological issues are raised whose future treatment is likely to affect the growth and impact of grounded cognition.

    Weight regain frequently follows interventions that reduce body weight, leading to a failure in long-term obesity treatment. Inhibitory proteins of the leptin signaling pathway, such as the suppressor of cytokine signaling 3 (SOCS3), have been studied in conditions that predispose animals to obesity. However, whether SOCS3 modulates postrestriction hyperphagia and weight regain remains unknown. Mice lacking SOCS3 protein specifically in leptin receptor (LepR)-expressing cells (LepR SOCS3 knockout [KO]) were generated and studied in fasting and refeeding conditions. LepR SOCS3 KO mice exhibited increased leptin sensitivity in the hypothalamus. Notably, LepR SOCS3 KO males and females showed attenuated food intake and weight regain after 48 hours of fasting. Postrestriction hyperleptinemia was also prevented in LepR SOCS3 KO mice. Next, we studied possible mechanisms and neural circuits involved in the SOCS3 effects. SOCS3 deletion did not prevent fasting- or refeeding-induced c-Fos expression in the arcuate nucleus of the hypothalamus (ARH) nor fasting-induced increased excitability of ARH LepR-expressing cells. On the other hand, SOCS3 ablation reduced the mRNA levels of hypothalamic orexigenic neuropeptides during fasting (neuropeptide Y, agouti-related protein, orexin, and melanin-concentrating hormone). In summary, our findings suggest that increased leptin sensitivity contributes to the maintenance of a reduced body weight after food deprivation. In addition, the attenuated postrestriction food intake observed in mutant mice was not explained by fasting-induced changes in the activity of ARH neurons but exclusively by a lower transcription of orexigenic neuropeptides during fasting. These results indicate a partial dissociation between the regulation of neuronal activity and gene expression in ARH LepR-expressing cells.

    Weight loss reduces abdominal and intrahepatic fat, thereby improving metabolic and cardiovascular risk. Yet, many patients regain weight after successful diet-induced weight loss. Long-term changes in abdominal and liver fat, along with liver test results and insulin resistance, are not known. We analyzed 50 overweight to obese subjects (46 ± 9 years of age; BMI, 32.5 ± 3.3 kg/m2; women, 77%) who had participated in a 6-month hypocaloric diet and were randomized to either reduced carbohydrates or reduced fat content. Before, directly after diet, and at an average of 24 (range, 17-36) months follow-up, we assessed body fat distribution by magnetic resonance imaging and markers of liver function and insulin resistance. Body weight decreased with diet but had increased again at follow-up. Subjects also partially regained abdominal subcutaneous and visceral adipose tissue. In contrast, intrahepatic fat decreased with diet and remained reduced at follow-up (7.8 ± 9.8% [baseline], 4.5 ± 5.9% [6 months], and 4.7 ± 5.9% [follow-up]). Similar patterns were observed for markers of liver function, whole-body insulin sensitivity, and hepatic insulin resistance. Changes in intrahepatic fat und intrahepatic function were independent of macronutrient composition during intervention and were most effective in subjects with nonalcoholic fatty liver disease at baseline. A 6-month hypocaloric diet induced improvements in hepatic fat, liver test results, and insulin resistance despite regaining of weight up to 2 years after the active intervention. Body weight and adiposity measurements may underestimate beneficial long-term effects of dietary interventions.

    2010-03-01

    Full Text Available Abstract Background Increased transcription of oncogenes like the epidermal growth factor receptor (EGFR is frequently caused by amplification of the whole gene or at least of regulatory sequences. Aim of this study was to pinpoint mechanistic parameters occurring during egfr copy number gains leading to a stable EGFR overexpression and high sensitivity to extracellular signalling. A deeper understanding of those marker events might improve early diagnosis of cancer in suspect lesions, early detection of cancer progression and the prediction of egfr targeted therapies. Methods The basal-like/stemness type breast cancer cell line subpopulation MDA-MB-468 CD44high/CD24-/low, carrying high egfr amplifications, was chosen as a model system in this study. Subclones of the heterogeneous cell line expressing low and high EGF receptor densities were isolated by cell sorting. Genomic profiling was carried out for these by means of SNP array profiling, qPCR and FISH. Cell cycle analysis was performed using the BrdU quenching technique. Results Low and high EGFR expressing MDA-MB-468 CD44+/CD24-/low subpopulations separated by cell sorting showed intermediate and high copy numbers of egfr, respectively. However, during cell culture an increase solely for egfr gene copy numbers in the intermediate subpopulation occurred. This shift was based on the formation of new cells which regained egfr gene copies. By two parametric cell cycle analysis clonal effects mediated through growth advantage of cells bearing higher egfr gene copy numbers could most likely be excluded for being the driving force. Subsequently, the detection of a fragile site distal to the egfr gene, sustaining uncapped telomere-less chromosomal ends, the ladder-like structure of the intrachromosomal egfr amplification and a broader range of egfr copy numbers support the assumption that dynamic chromosomal rearrangements, like breakage-fusion-bridge-cycles other than proliferation drive the gain

    The first scene opens with the music of Shirley Bassey. The astronomer Henrietta Swan Leavitt is writing a diary when visited by the famous CBS reporter Edward Roscoe Murrow. Henrietta is surprised that this American television channel should want to pay such a tribute to her, but she agrees to be interviewed. Annie Jump Cannon, her friend and colleague from Harvard College Observatory, accompanies her during most of the sessions. Everything goes so well that the journalist tries to touch on certain issues that Henrietta seems to want to keep secret, such as her relationship with Edward Charles Pickering, Director of the Observatory, and the reason why she failed to get the recognition for her work that she deserved.This is the argument of the play The Lost Honor of Henrietta Leavitt, a project of the Museo de la Ciencia y el Cosmos (Museum of Science and the Cosmos), run by the Organismo Autonomo de Museos y Centros of Cabildo de Tenerife (Autonomous Organism of Museums and Centres of the island government, Cabildo of Tenerife), with funding from the Spanish Foundation for Science and Technology (FECYT) and designed for the International Year of Astronomy 2009. The play, written and directed by the author, Carmen del Puerto, has been staged eight times in Tenerife and Pamplona. The poster values this experience as a resource for scientific popularization.

  5. America’s Lost Innocence and Cinema

    2015-10-01

    Full Text Available In my paper America’s Lost Innocence I intend to focus on American cinema of the ’50s, part of ’60s, and contemporary throwbacks to those decades. The ’50s have been called “the last decade of American innocence”, “the happiest decade in America’s history – when things were going on – that everybody misses” (by Jean Baudrillard. That era symbolically ceased on 22 November 1963; however, many scholars and publicists undermine the belief in its very existence. Michael Wood calls the ’50s a time of “self-deception”; therefore, the question raised is – has America ever been innocent? By concentrating on the message conveyed by mostly genre (e.g. drama, melodrama, musical, romantic comedy and mainstream movies made in the ’50s and early ’60s (e.g. A Place In the Sun, Cat on the Hot, Tin Roof, Home From the Hill, I intend to analyze the portrait of American society of that time, it’s rules and expectations towards individuals and system as a whole. In the second part of my paper I will focus on contemporary throwbacks to those times depicted mostly in movies made in the 21st century, although not exclusively (e.g. Far From Heaven, The Hours, Revolutionary Road, the TV series Mad Men [2007–], Pleasantville. Using those and other movies as examples, I intend to prove the thesis that the phenomenon of retro and contemporary retromania are not always and not by definition conservative, and can serve as a means to a critical approach towards society.

    Metabolic adaptations occur with weight loss that result in increased hunger with discordant simultaneous reductions in energy requirements-producing the so-called energy gap in which more energy is desired than is required. The increased hunger is associated with elevation of the orexigenic hormone ghrelin and decrements in anorexigenic hormones. The lower total daily energy expenditure with diet-induced weight loss results from (1) a disproportionately greater decrease in circulating leptin and resting metabolic rate (RMR) than would be predicted based on the decline in body mass, (2) decreased thermic effect of food (TEF), and (3) increased energy efficiency at work intensities characteristic of activities of daily living. These metabolic adaptations can readily promote weight regain. While more experimental research is needed to identify effective strategies to narrow the energy gap and attenuate weight regain, some factors contributing to long-term weight loss maintenance have been identified. Less hunger and greater satiation have been associated with higher intakes of protein and dietary fiber, and lower glycemic load diets. High levels of physical activity are characteristic of most successful weight maintainers. A high energy flux state characterized by high daily energy expenditure and matching energy intake may attenuate the declines in RMR and TEF, and may also result in more accurate regulation of energy intake to match daily energy expenditure.

    Few at-sea behavioural data exist for oceanic-stage neonate sea turtles, a life-stage commonly referred to as the sea turtle 'lost years'. Historically, the long-term tracking of small, fast-growing organisms in the open ocean was logistically or technologically impossible. Here, we provide the first long-term satellite tracks of neonate sea turtles. Loggerheads (Caretta caretta) were remotely tracked in the Atlantic Ocean using small solar-powered satellite transmitters. We show that oceanic-stage turtles (i) rarely travel in Continental Shelf waters, (ii) frequently depart the currents associated with the North Atlantic Subtropical Gyre, (iii) travel quickly when in Gyre currents, and (iv) select sea surface habitats that are likely to provide a thermal benefit or refuge to young sea turtles, supporting growth, foraging and survival. Our satellite tracks help define Atlantic loggerhead nursery grounds and early loggerhead habitat use, allowing us to re-examine sea turtle 'lost years' paradigms.

    The Big Lost River basin occupies about 1,400 square miles in south-central Idaho and drains to the Snake River Plain. The economy in the area is based on irrigation agriculture and stockraising. The basin is underlain by a diverse-assemblage of rocks which range, in age from Precambrian to Holocene. The assemblage is divided into five groups on the basis of their hydrologic characteristics. Carbonate rocks, noncarbonate rocks, cemented alluvial deposits, unconsolidated alluvial deposits, and basalt. The principal aquifer is unconsolidated alluvial fill that is several thousand feet thick in the main valley. The carbonate rocks are the major bedrock aquifer. They absorb a significant amount of precipitation and, in places, are very permeable as evidenced by large springs discharging from or near exposures of carbonate rocks. Only the alluvium, carbonate rock and locally the basalt yield significant amounts of water. A total of about 67,000 acres is irrigated with water diverted from the Big Lost River. The annual flow of the river is highly variable and water-supply deficiencies are common. About 1 out of every 2 years is considered a drought year. In the period 1955-68, about 175 irrigation wells were drilled to provide a supplemental water supply to land irrigated from the canal system and to irrigate an additional 8,500 acres of new land. Average. annual precipitation ranged from 8 inches on the valley floor to about 50 inches at some higher elevations during the base period 1944-68. The estimated water yield of the Big Lost River basin averaged 650 cfs (cubic feet per second) for the base period. Of this amount, 150 cfs was transpired by crops, 75 cfs left the basin as streamflow, and 425 cfs left as ground-water flow. A map of precipitation and estimated values of evapotranspiration were used to construct a water-yield map. A distinctive feature of the Big Lost River basin, is the large interchange of water from surface streams into the ground and from the

    A systematic study of Kodak’s annual operations and business strategies during 2000-2010revealed that Kodak management faltered in transitioning the Kodak Company from an analog business model to a digital business model.In 2000 Kodak delivered strong performance and it appeared to be smart to be in the picture business.In 2002Kodak was the best-performing stock among companies that made up the Dow Jones Industrial Average.In 2005Kodak future looked bright.A confident Chairman and CEO Antonio M.Perez pronounced that by 2008he expected all of Kodak’s businesses to be leaders in their industry segments.In 2008Kodak remained as the most recognized and respected brands in the world but it played in the hyper competitive markets in which price and technological advances drove the market.So Kodak was unable to reap premium prices from its famous brand and it became a nonviable business due to sustained losses from continuing operations.During 2008-2012 Kodak fell from being a market leader to becoming a bankrupt Company.Using the analogy of"behind the power curve",this article shines light on Kodak’s crash to the ground,i.e.bankruptcy filing in 2012and asserts that Kodak management triggered the process of falling behind the power curve in 2000when it embraced the infoimaging strategy to extend the benefits of film.Kodak’s 2003digital business model and other strategies that followed it did not allow Kodak to become a strong competitor in the digital world.Kodak digital camera business became a lost business opportunity.

    Laparoscopic Roux-en-Y gastric bypass (RYGB) is an effective treatment modality for severe obesity. Failure of weight loss and/or weight regain due to lack of restriction has been reported in long-term follow-up studies. The aim of this study is to determine the safety and effectiveness of reestablishing the restrictive component of the operation by trimming the pouch and/or anastomosis for pouch and/or anastomotic enlargement using a laparoscopic approach. We retrospectively reviewed our prospectively collected database for all patients that underwent revisional surgery of RYGB for weight regain or failure of weight loss. Percent excess weight loss (%EWL) and BMI loss (BMIL) were characterized into the following three time periods: (1) primary operation to pre-revision, (2) pre-revision to post-revision, and (3) primary operation to post-revision. Post-operative follow-up was at 6, 12, 18, 24, 36, and 48 months. Between 2005 and 2011, a total of 121 patients in the database underwent revision of RYGB. Forty-four patients were identified that fulfilled the aforementioned parameters. In this group, 30 patients underwent trimming of the pouch and/or redo anastomosis (TPA), 8 TPA and conversion from retrocolic to antecolic Roux limb, and 6 TPA with remnant gastrectomy. Mean follow-up period was 26.1 ± 22.7 months. The post-revision mean %EWL was 38%, and the BMI loss was 7 kg/m(2). In the pre-revision to 48 months post-revision time period, mean %EWL and BMIL were 28.6% and 4.9 kg/m(2) in the TPA-only group, 52% and 8.8 kg/m(2) in the TPA with conversion to antecolic, antegastric group, and 33.4% and 5.9 kg/m(2) in the TPA with gastrectomy group, respectively (%EWL, p = 0.096; BMIL, p = 0.227). One patient (2.3%) developed a left upper quadrant hematoma. There was no mortality in this series. Trimming of the pouch and/or anastomosis appears to be a safe and effective revisional modality for patients with insufficient weight loss or weight regain after

    Weight loss in obese humans produces a relative leptin deficiency, which is postulated to activate potent orexigenic and energy conservation mechanisms to restrict weight loss and promote weight regain. Here we determined whether leptin replacement alone or with GLP-1 receptor agonist exendin-4 attenuates weight regain or promotes greater weight loss in weight-reduced diet-induced obese (DIO) rats. Forty percent restriction in daily intake of a high-fat diet in DIO rats for 4 wk reduced body weight by 12%, body fat by 29%, and plasma leptin by 67% and normalized leptin sensitivity. When food restriction ended, body weight, body fat, and plasma leptin increased rapidly. Daily administration of leptin [3-h intraperitoneal (ip) infusions (4 nmol·kg(-1)·h(-1))] at onset and end of dark period for 3 wk did not attenuate hyperphagia and weight regain, nor did it affect mean daily meal sizes or meal numbers. Exendin-4 (50 pmol·kg(-1)·h(-1)) infusions during the same intervals prevented postrestriction hyperphagia and weight regain by normalizing meal size. Coadministration of leptin and exendin-4 did not reduce body weight more than exendin-4 alone. Instead, leptin began to attenuate the inhibitory effects of exendin-4 on food intake, meal size, and weight regain by the end of the second week of administration. Plasma leptin in rats receiving leptin was sevenfold greater than in rats receiving vehicle and 17-fold greater than in rats receiving exendin-4. Together, these results do not support the hypothesis that leptin replacement alone or with exendin-4 attenuates weight regain or promotes greater weight loss in weight-reduced DIO rats.

    After bariatric surgery, the majority of patients develop a problem with excessive hanging skin. This can negatively influence the psychological benefits associated with bariatric surgery. The present study aims to explore the relationship between overall impairment related to the presence of excessive skin, body image, depressive symptomatology, sexual functioning, and weight regain in a sample of women after bariatric surgery. Sixty-one women (body mass index (BMI) = 30.45 ± 5.35 kg/m(2)) with excessive skin who had undergone bariatric surgery 19.02 ± 9.98 months before were evaluated as part of a cross-sectional study using a semi-structured clinical interview and completed a set of self-report measures. A path analysis, an extension of multiple regression analysis, using IBM® SPSS® Amos™ was conducted to explore simultaneously the associations between the variables under study. The model tested with path analysis showed a good fit to the data (χ (2) = 1.241, df = 4, p = 0.871; Comparative Fit Index (CFI) = 1.000, Tucker-Lewis Index (TLI) = 1.138, Incremental Fit Index (IFI) = 1.049, Root-Mean-Square of Approximation (RMSEA) = 0.000) and suggests that sexual functioning and overall impairment caused by excessive skin were associated with concerns regarding body image and depressive symptomatology, which in turn relate to a greater percentage of total weight regain. These data stress the importance of considering sexual intimacy and body image in order to optimize psychological and weight outcomes after bariatric surgery.

    2011-01-01

    Full Text Available The story of the loss of paradise has been read and interpreted in different ages. Commentary on Milton's Paradise Lost is not limited to verbal texts; painters and illustrators have contributed greatly to the poem by presenting their own time-bound readings and interpretations of the poem through their illustrations that are far beyond mere decorations. John Martin, in the aftermath of the Industrial Revolution, deletes the Father and the Son from his illustrations. Only angels such as Raphael are the representations of deity and are as powerless and tiny as Adam and Eve. Adam and Eve, after the Fall seem as small, powerless and as subjugated to the natural surrounding as they were before the Fall. Satan is the only powerful figure in his elegant palace. Through a new historical outlook, the researchers aim at exposing the workings of ideology and dominant discourses that informed John Martin's pictorial reading of Milton's poem in the early 19th century

    A general thermodynamic analysis is given of dissipative self-assembly (DSA). Subsequently, the analysis is used to quantify the lost work in a recently published chemical realization of DSA (Boekhoven et al., Angew Chem Int Ed 49:4825, 2010) where a formation reaction produces the monomers that subsequently self-assemble and are finally annihilated by means of a destruction reaction. For this example, the work lost in self-assembly itself is found to be negligibly small compared to the work lost in the reactions driving the non-spontaneous formation reaction and the kinetically hindered destruction reaction.

  5. Finding the 'lost years' in green turtles: insights from ocean circulation models and genetic analysis.

    Organismal movement is an essential component of ecological processes and connectivity among ecosystems. However, estimating connectivity and identifying corridors of movement are challenging in oceanic organisms such as young turtles that disperse into the open sea and remain largely unobserved during a period known as 'the lost years'. Using predictions of transport within an ocean circulation model and data from published genetic analysis, we present to our knowledge, the first basin-scale hypothesis of distribution and connectivity among major rookeries and foraging grounds (FGs) of green turtles (Chelonia mydas) during their 'lost years'. Simulations indicate that transatlantic dispersal is likely to be common and that recurrent connectivity between the southwestern Indian Ocean and the South Atlantic is possible. The predicted distribution of pelagic juvenile turtles suggests that many 'lost years hotspots' are presently unstudied and located outside protected areas. These models, therefore, provide new information on possible dispersal pathways that link nesting beaches with FGs. These pathways may be of exceptional conservation concern owing to their importance for sea turtles during a critical developmental period.

  6. Space Radar Image of the Lost City of Ubar

    1999-01-01

    This is a radar image of the region around the site of the lost city of Ubar in southern Oman, on the Arabian Peninsula. The ancient city was discovered in 1992 with the aid of remote sensing data. Archeologists believe Ubar existed from about 2800 B.C. to about 300 A.D. and was a remote desert outpost where caravans were assembled for the transport of frankincense across the desert. This image was acquired on orbit 65 of space shuttle Endeavour on April 13, 1994 by the Spaceborne Imaging Radar C/X-Band Synthetic Aperture Radar (SIR-C/X-SAR). The SIR-C image shown is centered at 18.4 degrees north latitude and 53.6 degrees east longitude. The image covers an area about 50 by 100 kilometers (31 miles by 62 miles). The image is constructed from three of the available SIR-C channels and displays L-band, HH (horizontal transmit and receive) data as red, C-band HH as blue, and L-band HV (horizontal transmit, vertical receive) as green. The prominent magenta colored area is a region of large sand dunes, which are bright reflectors at both L-and C-band. The prominent green areas (L-HV) are rough limestone rocks, which form a rocky desert floor. A major wadi, or dry stream bed, runs across the middle of the image and is shown largely in white due to strong radar scattering in all channels displayed (L and C HH, L-HV). The actual site of the fortress of the lost city of Ubar, currently under excavation, is near the Wadi close to the center of the image. The fortress is too small to be detected in this image. However, tracks leading to the site, and surrounding tracks, appear as prominent, but diffuse, reddish streaks. These tracks have been used in modern times, but field investigations show many of these tracks were in use in ancient times as well. Mapping of these tracks on regional remote sensing images was a key to recognizing the site as Ubar in 1992. This image, and ongoing field investigations, will help shed light on a little known early civilization. Spaceborne

  17. Exercise decreases lipogenic gene expression in adipose tissue and alters adipocyte cellularity during weight regain after weight loss.

    Directory of Open Access Journals (Sweden)

    Erin Danielle Giles

    2016-02-01

    Full Text Available Exercise is a potent strategy to facilitate long-term weight maintenance. In addition to increasing energy expenditure and reducing appetite, exercise also favors the oxidation of dietary fat, which likely helps prevent weight re-gain. It is unclear whether this exercise-induced metabolic shift is due to changes in energy balance, or whether exercise imparts additional adaptations in the periphery that limit the storage and favor the oxidation of dietary fat. To answer this question, adipose tissue lipid metabolism and related gene expression were studied in obese rats following weight loss and during the first day of relapse to obesity. Mature, obese rats were weight-reduced for 2 weeks with or without daily treadmill exercise (EX. Rats were weight maintained for 6 weeks, followed by relapse on: a ad libitum low fat diet (LFD, b ad libitum LFD plus EX, or c a provision of LFD to match the positive energy imbalance of exercised, relapsing animals. 24h retention of dietary- and de novo-derived fat were assessed directly using 14C palmitate/oleate and 3H20, respectively. Exercise decreased the size, but increased the number of adipocytes in both retroperitoneal (RP and subcutaneous (SC adipose depots, and prevented the relapse-induced increase in adipocyte size. Further, exercise decreased the expression of genes involved in lipid uptake (CD36 & LPL, de novo lipogenesis (FAS, ACC1, and triacylglycerol synthesis (MGAT & DGAT in RP adipose during relapse following weight loss. This was consistent with the metabolic data, whereby exercise reduced retention of de novo-derived fat even when controlling for the positive energy imbalance. The decreased trafficking of dietary fat to adipose tissue with exercise was explained by reduced energy intake which attenuated energy imbalance during refeeding. Despite having decreased expression of lipogenic genes, the net retention of de novo-derived lipid was higher in both the RP and SC adipose of exercising

    1983-01-01

    A study of the utility of conventional lost circulation materials and testing methods was performed using a modified API slot tester. Five lost circulation materials were evaluated in 266 tests at both room temperature and temperature-aged conditions simulating expected geothermal environments. A large variation in the maximum pressure (or sealing pressure) the plug could withstand was attributed to nonrepeatability in plug strengths. Plugs were composed to multiple or single particle bridges, with the latter providing stronger, better sealing plugs. Seals occurred on the upstream surface of the slots in all cases. Sealing pressures generally decreased with increasing slot widths and decreasing solids concentration. When the slot width was less than the size of the largest rigid particle in the lost circulation slurry, sealing pressure was maximized. When the slot width was greater than three times the maximum rigid particle size, no significant sealing ability was observed with the conventional materials tested. Additionally, cellulosic lost circulation materials are severely degraded by temperature aging. Mud gellation provided no significant improvement in lost circulation material sealing ability.

    This article is a summary of the symposium "Modifying Eating Behavior: Novel Approaches for Reducing Body Weight, Preventing Weight Regain, and Reducing Chronic Disease Risk" held 29 April 2014 at the ASN Scientific Sessions and Annual Meeting at Experimental Biology 2014 in San Diego, CA. In this symposium, novel approaches to modifying eating behavior were highlighted, including 1) alteration of meal timing and macronutrient composition and 2) retraining and provision of feedback about eating behavior. Dr. Ciampolini discussed a method for teaching individuals to recognize a decrease in blood glucose concentration, and therefore the need for energy, by learning the associated physical sensations (signifying hunger). Dr. Madar and Sigal Sofer presented their work on reducing hunger during energy reduction by feeding carbohydrate only in the evening. Dr. Hamilton-Shield reviewed studies on the Mandometer (Mikrodidakt), a device for training individuals to slow eating rate. Finally, Dr. Sazonov presented information on a wearable device, the Automatic Ingestion Monitor, which senses jaw motion and/or hand-to-mouth gestures to detect and characterize food intake. His goal is to use the instrument to prevent overeating by providing feedback to the user to stop ingestion at a predetermined limit. © 2014 American Society for Nutrition.

    Predictors of weight loss (WL) or weight regain (WR) after Roux-en-Y gastric bypass (RYGBP) are not established. The aim of this study was to analyze the usefulness of some baseline peptides (leptin, insulin, and ghrelin) as biomarkers of WL and WR in morbid obese patients after RYGBP at long term. Seventy-six morbid obese (47 women, age 41.6 ± 9.6 years, body mass index [BMI] 52.1 ± 8 kg/m(2)) patients were evaluated at baseline and at 1, 2, and 6 years after surgery. Excess body weight loss after 6 years was of 63.9%. Age, BMI, and studied hormones at baseline or their changes over time did not predict long-term excess body weight loss. WR greater than 10% was observed in 36.8% of patients between 2 and 6 years of follow-up, but it was not correlated with BMI, age, or baseline peptide concentrations. Measurement of ghrelin, insulin, and leptin before surgery is not useful as predictors of WL or WR at long term after RYGBP. Copyright © 2015 Elsevier Inc. All rights reserved.

    Full Text Available Several factors may highlight the relevance of prostate cancer to the pre-heart-transplant population. First, the expansion in candidate selection criteria led to increased number of men over the age of fifty to be considered for heart transplantation. With the introduction of left ventricular assist device (LVAD therapy, waiting-list mortality has dramatically declined over the past decade. Additionally, transplant candidates are diligently screened for preexisting neoplasm while on the waiting list. Taken together, screening-detected prostate cancer may increasingly be diagnosed in patients on the waiting list. If discovered, it will pose unique challenge to clinicians as to date there has been no universally accepted management guideline. We report a case of LVAD-treated heart transplant candidate diagnosed with prostate cancer while on the waiting list. Patient screening demonstrated PSA elevation which prompted prostate biopsy. Low-risk clinically localized prostate cancer was confirmed and led to removal of patient from transplant list. When counseled regarding management of his cancer, the patient elected to undergo radical prostatectomy in a hope to regain candidacy for heart transplantation. Despite being of high surgical risk, multidisciplinary team approach led to successful management of prostate cancer and the patient eventually received heart transplant one year following prostatectomy.

    Full Text Available Abstract Background Monogynous mating systems with extremely low male mating rates have several independent evolutionary origins and are associated with drastic adaptations involving self-sacrifice, one-shot genitalia, genital damage, and termination of spermatogenesis immediately after maturation. The combination of such extreme traits likely restricts evolutionary potential perhaps up to the point of making low male mating rates irreversible and hence may constitute an evolutionary dead end. Here, we explore the case of a reversion to multiple mating from monogynous ancestry in golden orb-web spiders, Nephila senegalensis. Results Male multiple mating is regained by the loss of genital damage and sexual cannibalism but spermatogenesis is terminated with maturation, restricting males to a single loading of their secondary mating organs and a fixed supply of sperm. However, males re-use their mating organs and by experimentally mating males to many females, we show that the sperm supply is divided between copulations without reloading the pedipalps. Conclusion By portioning their precious sperm supply, males achieve an average mating rate of four females which effectively doubles the maximal mating rate of their ancestors. A heritage of one-shot genitalia does not completely restrict the potential to increase mating rates in Nephila although an upper limit is defined by the available sperm load. Future studies should now investigate how males use this potential in the field and identify selection pressures responsible for a reversal from monogynous to polygynous mating strategies.

    To study the effects of 13 weeks conjugated linoleic acid (CLA) supplementation in overweight subjects after weight loss on weight regain, body composition, resting metabolic rate, substrate oxidation, and blood plasma parameters. This study had a double-blind, placebo-controlled randomized design. Subjects were first submitted to a very-low-calorie diet (VLCD 2.1 MJ/d) for 3 weeks after which they started with the 13-week intervention period. They either received 1.8 g CLA or placebo per day (low dosage, LD) or 3.6 g CLA or placebo per day (high dosage, HD). A total of 26 men and 28 women (age 37.8+/-7.7 y; body mass index (BMI) 27.8+/-1.5 kg/m(2)). Before VLCD (t=-3), after VLCD but before CLA or placebo intervention (t=0) and after 13-week CLA or placebo intervention (t=13), body weight, body composition (hydrodensitometry and deuterium dilution), resting metabolic rate, substrate oxidation, physical activity, and blood plasma parameters (glucose, insulin, triacylglycerol, free fatty acids, glycerol and beta-hydroxy butyrate) were measured. The VLCD significantly lowered body weight (6.9+/-1.7%), %body fat, fat mass, fat-free mass, resting metabolic rate, respiratory quotient and plasma glucose, insulin, and triacylglycerol concentrations, while free fatty acids, glycerol and beta-hydroxy butyrate concentrations were increased. Multiple regression analysis showed that at the end of the 13-week intervention, CLA did not affect %body weight regain (CLA LD 47.9+/-88.2%, CLA HD 27.4+/-29.8%, Placebo LD 32.0+/-42.8%, Placebo HD 22.5+/-37.9%). The regain of fat-free mass was increased by CLA (LD 6.2+/-3.9, HD 4.6+/-2.4%) compared to placebo (LD 2.8+/-3.2%, HD 3.4+/-3.6%), independent of %body weight regain and physical activity. As a consequence of an increased regain of fat-free mass by CLA, resting metabolic rate was increased by CLA (LD 12.0+/-11.4%, HD 13.7+/-14.4%) compared to placebo (LD 9.1+/-11.0%, HD 8.6+/-8.5%).

    Based on the characteristics of the lost foam casting (LFC) and the artificial neural network technique, a mathematicalmodel for the simulation of the melt-pattern interface movement during the mold filling of LFC has been proposed andexperimentally verified. The simulation results are consistent with the experiments in both the shapes of melt frontand filling sequences. According to the calculated interface locations, the fluid flow and the temperature distributionsduring the mold filling and solidification processes were calculated, and the shrinkage defect of a lost foam ductileiron casting was predicted by considering the mold wall movement in LFC. The simulation method was applied tooptimize the casting design of lost foam ductile iron castings. It is shown that the model can be used for the defectsprediction and for casting design optimization in the practical LFC production.

    Full Text Available Customers represent company's most valuable asset. Company can assure its survival, further growth and development by retaining existing, attracting new and returning lost customers. Retaining existing, loyal customers is the most profitable business activity, attracting new ones is the most expensive, while returning lost and frequently forgotten customers is a type of business activity that still generates modest interest among researchers and practitioners. So far, marketing strategies have been mainly directed towards the first two categories of customers. The objective of this paper is dedicated to customer defection and returning lost customers. Paper discusses customer relationship life-cycle and the significance of managing customer return within it, types of customer defections, the process of managing return, as well as, the reasons that led to customer defection.

    During hibernation, thirteen-lined ground squirrels (Ictidomys tridecemlineatus) regularly cycle between bouts of torpor and interbout arousal (IBA). Most of the brain is electrically quiescent during torpor but regains activity quickly upon arousal to IBA, resulting in extreme oscillations in energy demand during hibernation. We predicted increased functional capacity of brain mitochondria during hibernation compared with spring to accommodate the variable energy demands of hibernation. To address this hypothesis, we examined mitochondrial bioenergetics in the ground squirrel brain across three time points: spring (SP), torpor (TOR), and IBA. Respiration rates of isolated brain mitochondria through complex I of the electron transport chain were more than twofold higher in TOR and IBA than in SP (P mitochondria compared with TOR and IBA (P mitochondria function more effectively during the hibernation season, allowing for rapid production of energy to meet demand when extreme physiological changes are occurring.

    Patients who undergo bariatric surgery often have inadequate weight loss or weight regain. We sought to discern the utility of weight loss pharmacotherapy as an adjunct to bariatric surgery in patients with inadequate weight loss or weight regain. Two academic medical centers. We completed a retrospective study to identify patients who had undergone bariatric surgery in the form of a Roux-en-Y gastric bypass (RYGB) or a sleeve gastrectomy from 2000-2014. From this cohort, we identified patients who were placed on weight loss pharmacotherapy postoperatively for inadequate weight loss or weight regain. We extracted key demographic data, medical history, and examined weight loss in response to surgery and after the initiation of weight loss pharmacotherapy. A total of 319 patients (RYGB = 258; sleeve gastrectomy = 61) met inclusion criteria for analysis. More than half (54%; n = 172) of all study patients lost≥5% (7.2 to 195.2 lbs) of their total weight with medications after surgery. There were several high responders with 30.3% of patients (n = 96) and 15% (n = 49) losing≥10% (16.7 to 195.2 lbs) and≥15% (25 to 195.2 lbs) of their total weight, respectively, Topiramate was the only medication that demonstrated a statistically significant response for weight loss with patients being twice as likely to lose at least 10% of their weight when placed on this medication (odds ratio = 1.9; P = .018). Regardless of the postoperative body mass index, patients who underwent RYGB were significantly more likely to lose≥5% of their total weight with the aid of weight loss medications. Weight loss pharmacotherapy serves as a useful adjunct to bariatric surgery in patients with inadequate weight loss or weight regain. Copyright © 2017 American Society for Bariatric Surgery.

    Clinically relevant weight loss is achievable through lifestyle modification, but unintentional weight regain is common. We investigated whether recently discovered genetic variants affect weight loss and/or weight regain during behavioral intervention. Participants at high-risk of type 2 diabetes (Diabetes Prevention Program [DPP]; N = 917/907 intervention/comparison) or with type 2 diabetes (Look AHEAD [Action for Health in Diabetes]; N = 2,014/1,892 intervention/comparison) were from two parallel arm (lifestyle vs. comparison) randomized controlled trials. The associations of 91 established obesity-predisposing loci with weight loss across 4 years and with weight regain across years 2-4 after a minimum of 3% weight loss were tested. Each copy of the minor G allele of MTIF3 rs1885988 was consistently associated with greater weight loss following lifestyle intervention over 4 years across the DPP and Look AHEAD. No such effect was observed across comparison arms, leading to a nominally significant single nucleotide polymorphism×treatment interaction (P = 4.3 × 10(-3)). However, this effect was not significant at a study-wise significance level (Bonferroni threshold P < 5.8 × 10(-4)). Most obesity-predisposing gene variants were not associated with weight loss or regain within the DPP and Look AHEAD trials, directly or via interactions with lifestyle. © 2015 by the American Diabetes Association.

    A dilated gastrojejunal anastomosis (GJA) is thought to be associated with weight regain in patients with Roux-en-Y gastric bypass (RYGB). Due to a high rate of perioperative morbidity, surgical revision is not generally performed. The aim of this study was to assess the technical feasibility, safety, and early outcomes of a procedure using a commercially available endoscopic suturing device to reduce the diameter of the GJA. This was a retrospective analysis of 25 consecutive patients who underwent transoral outlet reduction (TORe) for dilated GJA and weight regain. An endoscopic suturing device was used to place sutures at the margin of the GJA in order to reduce its aperture. On chart review, clinical data were available at 3, 6, and 12 months. Patients had regained a mean of 24 kg from their weight loss nadir and had a mean body mass index of 43 kg/m2 at the time of endoscopic revision. Average anastomosis diameter was 26.4 mm. Technical success was achieved in all patients (100 %) with a mean reduction in anastomosis diameter to 6 mm (range 3 - 10 mm), representing a 77.3 % reduction. The mean weight loss in successful cases was 11.5 kg, 11.7 kg, and 10.8 kg at 3, 6, and 12 months, respectively. There were no major complications. This case series demonstrated the technical feasibility, safety, and efficacy of performing gastrojejunostomy reduction using a commercially available endoscopic suturing device. This technique may represent an effective and minimally invasive option for the management of weight regain in patients with RYGB. © Georg Thieme Verlag KG Stuttgart · New York.

    There is currently no standard clinical refeeding diet for the treatment of anorexia nervosa (AN). To provide the most efficacious AN clinical care, it is necessary to define the metabolic effects of current refeeding diets. An activity-based model of anorexia nervosa (AN) was used in female rats. AN was induced over 7d by timed access to low fat (LF) diet with free access to a running wheel. Plasma hormones/metabolites and body composition were assessed at baseline, AN diagnosis (day 0), and following 28d of refeeding on LF diet. Energy balance and expenditure were measured via continuous indirect calorimetry on days -3 to +3. AN induction caused stress as indicated by higher levels of corticosterone versus controls (p weight gain during refeeding was higher in AN rats than controls (p = 0.0188), despite lower overall energy intake (p weight as controls. It is possible that liver lipid accumulation was caused by overfeeding of carbohydrate suggesting that a lower carbohydrate, higher fat diet may be beneficial during AN treatment. To test whether such a diet would be accepted clinically, we conducted a study in adolescent female AN patients which showed equivalent palatability and acceptability for LF and moderate fat diets. In addition, this diet was feasible to provide clinically during inpatient treatment in this population. Refeeding a LF diet to restore body weight in female AN rats caused depressed TEE and REE which facilitated rapid regain. However, this weight gain was metabolically unhealthy as it resulted in elevated lipid accumulation in the liver. It is necessary to investigate the use of other diets, such as lower carbohydrate, moderate fat diets, in pre-clinical models to develop the optimal clinical refeeding diets for AN.

    In excess of 55% of adults in the United States are classified as either overweight (body mass index = 25-29.9 kg.m(-2)) or obese (body mass index > or = 30 kg.m(-2)). To address this significant public health problem, the American College of Sports Medicine recommends that the combination of reductions in energy intake and increases in energy expenditure, through structured exercise and other forms of physical activity, be a component of weight loss intervention programs. An energy deficit of 500-1000 kcal.d-1 achieved through reductions in total energy intake is recommended. Moreover, it appears that reducing dietary fat intake to obese adults should progressively increase to this initial exercise goal. However, there may be advantages to progressively increasing exercise to 200-300 min (3.3-5 h) of exercise per week, as recent scientific evidence indicates that this level of exercise facilitates the long-term maintenance of weight loss. The addition of resistance exercise to a weight loss intervention will increase strength and function but may not attenuate the loss of fat-free mass typically observed with reductions in total energy intake and loss of body weight. When medically indicated, pharmacotherapy may be used for weight loss, but pharmacotherapy appears to be most effective when used in combination with modifications of both eating and exercise behaviors. The American College of Sports Medicine recommends that the strategies outlined in this position paper be incorporated into interventions targeting weight loss and the prevention of weight regain for adults.

    Bariatric surgery, especially Roux-en-Y gastric bypass is an effective treatment for refractory morbid obesity, causing the loss of 75% of initial excess weight. After the surgery, however, weight regain can occur in 10-20% of cases. To help, endoscopic argon plasma coagulation (APC) is used to reduce the anastomotic diameter. Many patients who undergo this treatment, are not always familiar with this procedure and its respective precautions. The aim of this study was to determine how well the candidate for APC understands the procedure and absorbs the information provided by the multidisciplinary team. We prepared a questionnaire with 12 true/false questions to evaluate the knowledge of the patients about the procedure they were to undergo. The questionnaire was administered by the surgeon during consultation in the preoperative period. The patients were invited to fill out the questionnaire. We found out that the majority learned about the procedure through the internet. They knew it was an outpatient treatment, where the anesthesia was similar to that for endoscopy, and that they would have to follow a liquid diet. But none of them knew that the purpose of this diet was to improve local wound healing. Bariatric patients who have a second chance to resume weight loss, need continuous guidance. The internet should be used by the multidisciplinary team to promote awareness that APC will not be sufficient for weight loss and weight-loss maintenance in the long term. Furthermore, there is a need to clarify again the harm of drinking alcohol in the process of weight loss, making its curse widely known.

    Full Text Available The present study aimed to examine the independent and interactive effects of match location, match status, and quality of opposition on regaining possession, analysed by the type and zone of ball recovery, in matches played in the 2011-2012 UEFA Champions League. Twenty-eight matches of the knockout phase were evaluated post-event using a computerized notational analysis system. Multinomial logistic regression analysis was applied to identify the effects of the previously mentioned situational variables on ball recovery type and zone. Match status and quality of opposition main effects were observed for both dependent variables, while main effects of match location were only evident for ball recovery zone. Additionally, the interactions Match location * Quality of opposition and Match status * Quality of opposition were significant for both type and zone of ball recovery. Better teams employed more proactive defensive strategies, since, even when winning, they tried to sustain their defensive success on actions that aimed to gain the ball from the opponents. Results emphasized the tendency for home and losing teams to defend in more advanced pitch zones. Better-ranked teams were also more effective than worse-ranked teams in applying defensive pressure in more advanced pitch positions. The findings of the study suggest that the defensive strategies used by better teams imply more intense and organized collective processes in order to recover the ball directly from the opposing team. Furthermore, defending away from own goal and near the opponent's one seems to be associated with success in elite soccer.

    We tested genetic associations with weight loss and weight regain in the Diabetes Prevention Program, a randomized controlled trial of weight loss-inducing interventions (lifestyle and metformin) versus placebo. Sixteen obesity-predisposing single nucleotide polymorphisms (SNPs) were tested for association with short-term (baseline to 6 months) and long-term (baseline to 2 years) weight loss and weight regain (6 months to study end). Irrespective of treatment, the Ala12 allele at PPARG associated with short- and long-term weight loss (-0.63 and -0.93 kg/allele, P ≤ 0.005, respectively). Gene-treatment interactions were observed for short-term (LYPLAL1 rs2605100, P(lifestyle*SNP) = 0.032; GNPDA2 rs10938397, P(lifestyle*SNP) = 0.016; MTCH2 rs10838738, P(lifestyle*SNP) = 0.022) and long-term (NEGR1 rs2815752, P(metformin*SNP) = 0.028; FTO rs9939609, P(lifestyle*SNP) = 0.044) weight loss. Three of 16 SNPs were associated with weight regain (NEGR1 rs2815752, BDNF rs6265, PPARG rs1801282), irrespective of treatment. TMEM18 rs6548238 and KTCD15 rs29941 showed treatment-specific effects (P(lifestyle*SNP) < 0.05). Genetic information may help identify people who require additional support to maintain reduced weight after clinical intervention.

    Poland has one of the highest cervical cancer mortality rates in Europe. It is related to the problem of late diagnosis and low attendance rate in screening programs. The objective of the study has been to assess the annual production loss due to the cervical cancer morbidity and mortality in Poland in 2012. The outcomes have been to provide comprehensive information on cervical cancer's influence on population's ability to work and its overall economic burden for the society. The study has also provided the methodological framework for disease-related production losses in Polish settings. The human capital method was used. The production losses were calculated in both monetary and quantitative terms (working days lost) due to 4 following reasons: 1) temporary disability to work, 2) permanent disability, 3) informal care, and 4) mortality. Cervical cancer resulted in approx. 702 964 working days lost in 2012 due to absence at work for both patients and care givers and a total number of 957 678 working days lost due to patients' mortality. The total value of production lost was assessed at 111.4 million euros. More than 66% of this value was attributed to women's mortality. The calculation of production lost due to cervical cancer burden provides strong evidence to support adequate health promotion and disease prevention actions. Actions promoting cervical cancer screening should be intensified including workplace health promotion activities. Med Pr 2016;67(3):289-299.

    Few at-sea behavioural data exist for oceanic-stage neonate sea turtles, a life-stage commonly referred to as the sea turtle ‘lost years’. Historically, the long-term tracking of small, fast-growing organisms in the open ocean was logistically or technologically impossible. Here, we provide the first long-term satellite tracks of neonate sea turtles. Loggerheads (Caretta caretta) were remotely tracked in the Atlantic Ocean using small solar-powered satellite transmitters. We show that oceanic-stage turtles (i) rarely travel in Continental Shelf waters, (ii) frequently depart the currents associated with the North Atlantic Subtropical Gyre, (iii) travel quickly when in Gyre currents, and (iv) select sea surface habitats that are likely to provide a thermal benefit or refuge to young sea turtles, supporting growth, foraging and survival. Our satellite tracks help define Atlantic loggerhead nursery grounds and early loggerhead habitat use, allowing us to re-examine sea turtle ‘lost years’ paradigms. PMID:24598420

    Background: Weight loss (WL) is often followed by weight regain after an energy-restricted dietary intervention (DI). When people are following a diet, the volume of an adipocyte decreases by loss of triglycerides, which creates stress between the cell contents and the surrounding extracellular matrix (ECM). Previously, we observed that genetic variations in ECM genes are associated with an increased risk of weight regain.Objective: We investigated the relation between the expression of ECM genes during WL and a period of weight stabilization (WS) and the risk of weight regain.Design: In this randomized controlled trial, 61 healthy overweight or obese participants followed either a 5-wk very-low-calorie diet (VLCD; 500 kcal/d) or a 12-wk low-calorie diet (1250 kcal/d) (WL period) with a subsequent 4-wk WS period and a 9-mo follow-up. The WL and WS periods combined were considered the DI. Abdominal subcutaneous adipose tissue biopsy samples were collected for microarray analysis. Gene expression changes for a broad set of ECM-related genes were correlated with the weight-regain percentage (WR%).Results: A total of 26 of the 277 genes were significantly correlated with WR% during WL, WS, or the DI periods. Most correlations were observed in the VLCD group during the WS period. Four genes code for leukocyte-specific receptors. These and other genes belong to a group of 26 genes, among which the expression changes were highly correlated (r ≥ 0.7, P ≤ 0.001). This group could be divided into 3 subclusters linking to 2 biological processes-leukocyte integrin gene activity and ECM remodeling-and a link to insulin sensitivity was also apparent.Conclusions: Our present findings indicate the importance of adipose tissue leukocytes for the risk of weight regain. ECM modification also seems to be involved, and we observed a link to insulin sensitivity. This trial was registered at clinicaltrials.gov as NCT01559415. © 2017 American Society for Nutrition.

    Weight regain has led to an increase in revision of Roux-en-Y gastric bypass (RYGB) surgeries. There is no standardized approach to revisional surgery after failed RYGB. We performed an exhaustive literature search to elucidate surgical revision options. Our objective was to evaluate outcomes and complications of various methods of revision after RYGB to identify the option with the best outcomes for failed primary RYGB. A systematic literature search was conducted using the following search tools and databases: PubMed, Google Scholar, Cochrane Clinical Trials Database, Cochrane Review Database, EMBASE, and Allied and Complementary Medicine to identify all relevant studies describing revision after failed RYGB. Inclusion criteria comprised of revisional surgery for weight gain after RYGB. Of the 1200 articles found, only 799 were selected for our study. Of the 799, 24 studies, with a total of 866 patients, were included for a systematic review. Of the 24 studies, 5 were conversion to Distal Roux-en-y gastric bypass (DRYGB), 5 were revision of gastric pouch and anastomosis, 6 were revision with gastric band, 2 were revision to biliopancreatic diversion/duodenal switch (BPD/DS), and 6 were revision to endoluminal procedures (i.e., stomaphyx). Mean percent excess body mass index loss (%EBMIL) after revision up to 1 and 3-year follow-up for BPD/DS was 63.7 and 76 %, DRYGB was 54 and 52.2 %, gastric banding revision 47.6 and 47.3 %, gastric pouch/anastomosis revision 43.3 and 14 %, and endoluminal procedures at 32.1 %, respectively. Gastric pouch/anastomosis revision resulted in the lowest major complication rate at 3.5 % and DRYGB with the highest at 11.9 % when compared to the other revisional procedures. The mortality rate was 0.6 % which only occurred in the DRYGB group. All 866 patients in the 24 studies reported significant early initial weight loss after revision for failed RYGB. However, of the five surgical revision options considered, BPD/DS, DRYGB

    This prospective study examines bone density and structure over a two-year time period in women with anorexia nervosa (AN) under weight gain treatment. Twenty-four women with AN were examined at baseline and at two annual follow-up examinations. In 9 AN patients BMI increased whereas in 15 it remained unchanged or decreased. Dual energy X-ray absorptiometry (DXA) was performed on the lumbar spine, the femoral neck and the whole hip and three-dimensional peripheral quantitative computer tomography (3D-pQCT) was performed on the ultradistal radius. ANOVAs for repeated measures were used to examine change over time in BMI and bone parameters. At baseline, patients with increased BMI had significantly higher bone density of femoral neck and total hip, and higher levels in all 3D-pQCT parameters of the ultradistal radius, compared to the group with unchanged or decreased BMI. The two groups did not differ at baseline in bone density of the spine. ANOVAs showed that bone density of the total hip increased significantly and that overall bone density (D100), the density of the trabecular area (D.Trab.) and the cortical thickness (C.Th.) in the ultradistal radius decreased significantly. Group x time interactions showed that changes over time were different in the two groups with regard to spine density and in the parameters D100, D.Trab. and C.Th. of the ultradistal radius. In the group with increased BMI the spine density dropped at the first follow-up whereas at the second follow-up it rose again to baseline. Patients with unchanged or decreased BMI showed a small but steady increase in spine density. The group changes of D100, D.Trab. and C.Th. of the ultradistal radius all followed the same pattern. Bone mineral density at all locations measured with both technologies (DXA and 3D-pQCT) did not vary according to BMI changes. The course of bone density and structure at different locations was different, and, despite weight increase, bone regain appeared to need different

    We have concluded a laboratory study to evaluate the survival potential of polymeric materials used for lost circulation plugs in geothermal wells. We learned early in the study that these materials were susceptible to hydrolysis. Through a systematic program in which many potential chemical combinations were evaluated, polymers were developed which tolerated hydrolysis for eight weeks at 500 F. The polymers also met material, handling, cost, and emplacement criteria. This screening process identified the most promising materials. A benefit of this work is that the components of the polymers developed can be mixed at the surface and pumped downhole through a single hose. Further strength testing is required to determine precisely the maximum temperature at which extrusion through fractures or voids causes failure of the lost circulation plug.

    2016-06-01

    Laparoscopic cholecystectomy (LC) has become a popular and widespread procedure for the treatment of gallstone disease. There is still an increasing concern about specific complications of LC due to gallbladder perforation and spillage of bile and stones. Although unretrieved intraperitoneal gallstones rarely become symptomatic, their infective complications may cause serious morbidities even after a long interval from LC. We performed a review of the literature on the diagnosis, prevention, consequences, and management of lost gallstones. All studies with a focus on lost gallstones or perforated gallbladder were analyzed to evaluate the postoperative complications. Between 1991 and 2015, >250 cases of postoperative complications of spilled gallstones were reviewed in the surgical literature. The most common complications are intraperitoneal abscesses and fistulas. Confusing clinical pictures due to gallstones spreading in different locations makes diagnosis challenging. Even asymptomatic dropped gallstones may masquerade intraperitoneal neoplastic lesions. Every effort should be made to prevent gallbladder perforation; otherwise, they should be retrieved immediately during laparoscopy. In cases with multiple large spilled stones or infected bile, conversion to open surgery can be considered. Documentation in operative notes and awareness of patients about lost gallstones are mandatory to early recognition and treatment of any complications.

  3. Restoration of lost connectivity of partitioned wireless sensor networks

    2016-05-01

    Full Text Available The lost connectivity due to failure of large scale nodes plays major role to degrade the system performance by generating unnecessary overhead or sometimes totally collapse the active network. There are many issues and challenges to restore the lost connectivity in an unattended scenario, i.e. how many recovery nodes will be sufficient and on which locations these recovery nodes have to be placed. A very few centralized and distributed approaches have been proposed till now. The centralized approaches are good for a scenario where information about the disjoint network, i.e. number of disjoint segments and their locations are well known in advance. However, for a scenario where such information is unknown due to the unattended harsh environment, a distributed approach is a better solution to restore the partitioned network. In this paper, we have proposed and implemented a semi-distributed approach called Relay node Placement using Fermat Point (RPFP. The proposed approach is capable of restoring lost connectivity with small number of recovery relay nodes and it works for any number of disjoint segments. The simulation experiment results show effectiveness of our approach as compared to existing benchmark approaches.

    2014-06-01

    In the literature, weight regain or failure of weight loss has been reported in up to 35% of patients after Roux-en-Y gastric bypass (RYGB). Several revisional procedures have been suggested to reinitiate further weight loss in this group of patients, and placing a silastic ring around the pouch proximal to the gastrojejunostomy is one among those procedures. The aim of our study is to evaluate and compare the safety and efficacy of salvage banding using a pericardial patch after RYGB for further weight loss. Between December 2009 and April 2013, a total of 46 patients underwent revision with pericardial patch ring after RYGB for weight regain/failure of weight loss. A retrospective review of a prospectively collected database was performed, noting the outcomes and complications of the procedure. The mean body mass index at the time of revision was 40.1 ± 6.8 kg/m2. Mean percentage of excess weight loss was 23.4 ± 15.7%, 39.0 ± 27.4%, and 18.9 ± 20.5% at 6, 12 and 24 months after revision, respectively. Eight (17.4%) patients required a total of 11 readmissions due to nausea, vomiting, dysphagia and abdominal pain. Six (13.0%) patients underwent a total of six reoperations, including four patients with laparoscopic removal of the pericardial patch and another revision of RYGB, and two patients with repair of perforated ulcers. Revision with pericardial patch ring after gastric bypass for weight regain or failure of weight loss may not be feasible, safe and effective.

    2013-01-01

    Organismal movement is an essential component of ecological processes and connectivity among ecosystems. However, estimating connectivity and identifying corridors of movement are challenging in oceanic organisms such as young turtles that disperse into the open sea and remain largely unobserved during a period known as ‘the lost years’. Using predictions of transport within an ocean circulation model and data from published genetic analysis, we present to our knowledge, the first basin-scale hypothesis of distribution and connectivity among major rookeries and foraging grounds (FGs) of green turtles (Chelonia mydas) during their ‘lost years’. Simulations indicate that transatlantic dispersal is likely to be common and that recurrent connectivity between the southwestern Indian Ocean and the South Atlantic is possible. The predicted distribution of pelagic juvenile turtles suggests that many ‘lost years hotspots’ are presently unstudied and located outside protected areas. These models, therefore, provide new information on possible dispersal pathways that link nesting beaches with FGs. These pathways may be of exceptional conservation concern owing to their importance for sea turtles during a critical developmental period. PMID:23945687

    Bioturbation from earthworm's activity contributes to soil creep and soil carbon dynamics, and provide enough aeration conditions for agricultural practices all over the world. In developing countries where there is a long term misuse of pesticides for agricultural purposes, lost of these benefits from earthworms activity might already yielded negative effects in the current crop production. Little research has been performed on earthworms avoidance to pesticides in developing countries located in the tropics. Furthermore, the complete avoidance reaction (from attraction to 100% avoidance) from earthworms to most of the pesticides used in potato cultivation in developing countries like Colombia is incomplete as yet. Hence the aim of this study is to assess the lost of earthworm on the soils caused by different concentrations of pesticides and associated agricultural impacts caused by a lost in the soil bioturbation. As a first stage, we have studied earthworm's avoidance to pesticide concentration in a potato agricultural area located in Colombia. Local cultivated Eisenia fetida were exposed to four of the most frequent applied active ingredients in potato crops i.e. carbofuran, mancozeb, methamidophos and chlorpyriphos. Adult earthworm toxicity experiments were carried out in two soils, untreated grasslands under standard (ISO guidelines) and undisturbed conditions, and exposed to six different concentrations of the active ingredients. The results of the avoidance reaction on the standard soils were significant for carbofuran, mancoceb and chlorpyrifos. For each of the three active ingredients, we found i) overuse of pesticide, ii) applied dose of carbofuran, mancoceb and chlorpyrifos by the farmers potentially caused 20%, 11% and 9% of earthworms avoidance on the cultivated soils, respectively.

    This paper presents first experimental results for an IP telephony-based steganographic method called LACK (Lost Audio PaCKets steganography). This method utilizes the fact that in typical multimedia communication protocols like RTP (Real-Time Transport Protocol), excessively delayed packets are not used for the reconstruction of transmitted data at the receiver, i.e. these packets are considered useless and discarded. The results presented in this paper were obtained basing on a functional LACK prototype and show the method's impact on the quality of voice transmission. Achievable steganographic bandwidth for the different IP telephony codecs is also calculated.

    Purpose An evaluation of mortality due to infectious diseases in Poland in 1999–2012 and an analysis of standard expected years of life lost due to the above diseases. Methods The study material included a database created on the basis of 5,219,205 death certificates of Polish inhabitants, gathered between 1999 and 2012 and provided by the Central Statistical Office. Crude Death Rates (CDR), Standardized Death Rates (SDR) and Standard Expected Years of Life Lost (SEYLL) due to infectious and parasitic diseases were also evaluated in the study period as well as Standard Expected Years of Life Lost per living person (SEYLLp) and Standard Expected Years of Life Lost per dead person (SEYLLd). Time trends were evaluated with the application of joinpoint models and an annual percentage change in their values. Results Death certificates report that 38,261 people died due to infectious diseases in Poland in the period 1999–2012, which made up 0.73% of the total number of deaths. SDR caused by these diseases decreased, particularly in the male group: Annual Percentage Change (APC = -1.05; 95% CI:-2.0 to -0.2; p<0.05). The most positive trends were observed in mortality caused by tuberculosis (A15-A19) (APC = -5.40; 95% CI:-6.3 to -4.5; p<0.05) and also meningitis, encephalitis, myelitis and encephalomyelitis (G03-G04) (APC = -3.42; 95% CI:-4.7 to -2.1; p<0.05). The most negative mortality trends were observed for intestinal infectious diseases (A00-A09) Annual Average Percentage Change (AAPC = 7.3; 95% CI:3.1 to 11.7; p<0.05). SDR substantially decreased in the first half of the study period, but then significantly increased in the second half. Infectious and parasitic diseases contributed to a loss of around 37,000 standard expected years of life in 1999 and more than 28,000 in 2012. During the study period, the SEYLLp index decreased from 9.59 to 7.39 per 10,000 population and the SEYLLd index decreased from 14.26 to 10.34 years (AAPC = 2.3; 95% CI:-2,9 to -1.7; p<0

    On 14 March 1964 Richard Feynman, one of the greatest scientific thinkers of the 20th Century, delivered a lecture entitled 'The Motion of the Planets Around the Sun'. For thirty years this remarkable lecture was believed to be lost. But now Feynman's work has been reconstructed and explained in meticulous, accessible detail, together with a history of ideas of the planets' motions. The result is a vital and absorbing account of one of the fundamental puzzles of science, and an invaluable insight into Feynman's charismatic brilliance.

    Maurice Ravel had been subject to psychiatric disorder for many years when signs of organic brain disease appeared at the age of 52. Aphasia, apraxia, agraphia, and alexia became established some five years later. Musical creativity was lost. Alajouanine diagnosed cerebral atrophy with bilateral ventricular enlargement. Though Ravel's condition deteriorated progressively, generalised dementia was not apparent. He died in December 1937, after a craniotomy performed by Clovis Vincent, possibly from a subdural haematoma. Vincent's operative findings are described here. The likely cause of Ravel's illness was a restricted form of cerebral degeneration.

    Recent studies report a significant gain in bone mineral density (BMD) after diet-induced weight loss. This might be explained by a measurement artefact. We therefore investigated the impact of intra- and extra-osseous soft tissue composition on bone measurements by dual X-ray absorptiometry (DXA) in a longitudinal study of diet-induced weight loss and regain in 55 women and 17 men (19-46 years, BMI 28.2-46.8 kg/m(2)). Total and regional BMD were measured before and after 12.7 ± 2.2 week diet-induced weight loss and 6 months after significant weight regain (≥30%). Hydration of fat free mass (FFM) was assessed by a 3-compartment model. Skeletal muscle (SM) mass, extra-osseous adipose tissue, and bone marrow were measured by whole body magnetic resonance imaging (MRI). Mean weight loss was -9.2 ± 4.4 kg (P BMAT) were not related to changes in BMD.

    Full Text Available Background: The aim of this study was to assess the economic burden of fire-related injury from two perspectives: post-injury social security compensations and also productivity losses due to the lost productive time from a societal perspective induced by the injury. Design and methods: A cohort of 1503 inpatients who sustained firerelated injury during the period 2001–2005 was retrospectively followed up for 5-10 years until the end of 2010, using linkages between several administrative registers. The study process was started in 2015 and finalized on March 2016. Results: Annual productivity loss was on average EUR 5.72 million, giving a total for the five-year study period of EUR 28.6 million, with a mean value of EUR 19,070 per person. Mean/median disability time for those who received benefits was 572/63 days, ranging from 3 days to 36.5 years. Total average cost of benefits to the injured annually during the study period was EUR 1.03 million. This equates to EUR 3430 per patient for the whole cohort or EUR 14,860 for those who received benefits. Conclusions: The burden of fire-related injuries in terms of payment transfers and lost productivity due to periods of disability as indirect costs is high; in a population of 5.4 million, the annual loss exceeded EUR 5.7 million. The results could be used in planning preventive measures and therefore yield savings

    Full Text Available The paper discusses some aspects of ecology in the use of lost foam patterns for piece production of large castings poured from ferrousalloys under the conditions of Metalodlew SA. Foundry. The technological processes used in the manufacture of castings are related with numerous hazards. Numerous problems requiring prompt solution occur also during the process of foundry mould pouring, to mention only various contaminants, air pollution, noise and other factors harmful to the human health and natural environment. Varioustechnological processes cause strenuous work conditions in foundry shops. Many of the publications that have appeared so far dealing withthe problems of environmental protection and hard work conditions in foundries [1, 2, 3, 4, 5, 6, 7, 8, 9] discuss in both general anddetailed way problems related with various pollutants, noise and other factors harmful to the human health and natural environment,responsible for hazards faced by foundry workers. Studies carried out by various R&D centres are mainly focussed on the problem of howto reduce the harmful effect of technological processes on the environment through modification of the already existing or development of new ecological and energy-saving materials and technologies. This paper shows the opportunities and threats resulting from the application of the Lost Foam Process in a foundry, which up to now has been using a more traditional technology.

    In recent years, so-called 'lost crops' have been appraised in a number of reviews, among them Lablab purpureus in the context of African vegetable species. This crop cannot truly be considered 'lost' because worldwide more than 150 common names are applied to it. Based on a comprehensive literature review, this paper aims to put forward four theses, (i) Lablab is one of the most diverse domesticated legume species and has multiple uses. Although its largest agro-morphological diversity occurs in South Asia, its origin appears to be Africa. (ii) Crop improvement in South Asia is based on limited genetic diversity. (iii) The restricted research and development performed in Africa focuses either on improving forage or soil properties mostly through one popular cultivar, Rongai, while the available diversity of lablab in Africa might be under threat of genetic erosion. (iv) Lablab is better adapted to drought than common beans (Phaseolus vulgaris) or cowpea (Vigna unguiculata), both of which have been preferred to lablab in African agricultural production systems. Lablab might offer comparable opportunities for African agriculture in the view of global change. Its wide potential for adaptation throughout eastern and southern Africa is shown with a GIS (geographic information systems) approach.

  2. The lost sunspot cycle: New support from Be10 measurements

    2014-01-01

    It has been suggested that the deficit in the number of spots on the surface of the Sun between 1790 and 1830, known as the Dalton minimum, contained an extra cycle that was not identified in the original sunspot record by Wolf. Though this cycle would be shorter and weaker than the average solar cycle, it would shift the magnetic parity of the solar magnetic field of the earlier cycles. This extra cycle is sometimes referred to as the 'lost solar cycle' or 'cycle 4b'. Here we reanalyse Be10 measurements with annual resolution from the NGRIP ice core in Greenland in order to investigate if the hypothesis regarding a lost sunspot cycle is supported by these measurements. Specifically, we make use of the fact that the Galactic cosmic rays, responsible for forming Be10 in the Earth's atmosphere, are affected differently by the open solar magnetic field during even and odd solar cycles. This fact enables us to evaluate if the numbering of cycles earlier than cycle 5 is correct. For the evaluation, we use Bayesian...

    Full Text Available This article is an attempt to interpret Witold Gombrowicz’s first novel in the context of cynicism, which is first conceptualized within the Foucauldian tradition as a practice of “frank speech” (parrhesia, and then, according to Peter Sloterdijk’s critical philosophy, as a form of modern consciousness based on inverted idealism. The opposition between an ancient subversive cynicism and its modern schizoid form allows one to analyze the complexity of Ferdydurke. In the course of interpretation it turns out that there are some intersecting planes: the protagonist searches in vain for lost insolence, but it is the author who manages to find it at the end of the novel.

  10. The lost-foam casting of aluminum alloy components

    Shivkumar, S.; Wang, L.; Apelian, D.

    1990-11-01

    In the lost-foam casting process, liquid metal is poured directly onto a refractory-coated, foamed polymer pattern which is buried in loose sand. The polymer pattern undergoes thermal degradation and is gradually replaced by the molten metal, which solidifies and produces the casting. The inherent operating advantages of this innovative technique have generated considerable interest among casting manufacturers. Currently, the process is being utilized to manufacture a wide variety of ferrous and nonferrous components catering primarily to the automotive industry. Because the process is relatively new, there is a compelling need to quantify the influence of process parameters on microstructure and mechanical properties. Furthermore, the interaction of the thermal degradation products with the solidifying metal may produce several unique defects in the casting.

    The aim of this paper is to find lost siblings of the Sun by analyzing high resolution spectra. Finding solar siblings will enable us to constrain the parameters of the parental cluster and the birth place of the Sun in the Galaxy. The solar siblings can be identified by accurate measurements of metallicity, stellar age and elemental abundances for solar neighbourhood stars. The solar siblings candidates were kinematically selected based on their proper motions, parallaxes and colours. Stellar parameters were determined through a purely spectroscopic approach and partly physical method, respectively. Comparing synthetic with observed spectra, elemental abundances were computed based on the stellar parameters obtained using a partly physical method. A chemical tagging technique was used to identify the solar siblings. We present stellar parameters, stellar ages, and detailed elemental abundances for Na, Mg, Al, Si, Ca, Ti, Cr, Fe, and Ni for 32 solar sibling candidates. Our abundances analysis shows that four ...

    2001-10-01

    The LOST2 system is a new accurate underwater positioning system that nonlinearly combines parts of dead-reckoning, acoustic-based positioning, and terrain-based positioning. The system is composed of two major subsystems, a system observer and a constrained extended Kalman filter. Inputs to the system are as follows: (1)high resolution bathymetry, (2)measured ocean depth at the position of the vessel, (3)measured or estimated vessel velocity, (4)slant range to and position of a known point, and (5)an initial prediction of the vessel's location. The system development, simulation studies, results from sea trials and some suggestions for future work are presented. The system is capable of providing position estimates with the same degree of accuracy as present methods, with significantly less hardware. These results prove the concept of the system as a new method to position underwater vessels.

    2016-01-01

    21 cm intensity mapping has emerged as a promising technique to map the large-scale structure of the Universe, at redshifts $z$ from 1 to 10. Unfortunately, many of the key cross correlations with photo-$z$ galaxies and the CMB have been thought to be impossible due to foreground contamination for radial modes with small wavenumbers. These modes are usually subtracted in the foreground subtraction process. We recover the lost 21 cm radial modes via cosmic tidal reconstruction and find more than 60\\% cross-correlation signal at $\\ell\\lesssim100$ and even more on larger scales can be recovered from null. The tidal reconstruction method opens up a new set of possibilities to probe our Universe and is extremely valuable not only for 21 cm surveys but also for CMB and photometric redshift observations.

  18. The transcription factor REST is lost in aggressive breast cancer.

    Full Text Available The function of the tumor suppressor RE1 silencing transcription factor (REST is lost in colon and small cell lung cancers and is known to induce anchorage-independent growth in human mammary epithelial cells. However, nothing is currently known about the role of this tumor suppressor in breast cancer. Here, we test the hypothesis that loss of REST function plays a role in breast cancer. To assay breast tumors for REST function, we developed a 24-gene signature composed of direct targets of the transcriptional repressor. Using the 24- gene signature, we identified a previously undefined RESTless breast tumor subtype. Using gene set enrichment analysis, we confirmed the aberrant expression of REST target genes in the REST-less tumors, including neuronal gene targets of REST that are normally not expressed outside the nervous system. Examination of REST mRNA identified a truncated splice variant of REST present in the REST-less tumor population, but not other tumors. Histological analysis of 182 outcome-associated breast tumor tissues also identified a subpopulation of tumors that lack full-length, functional REST and over-express the neuroendocrine marker and REST target gene Chromogranin A. Importantly, patients whose tumors were found to be REST-less using either the 24-gene signature or histology had significantly poorer prognosis and were more than twice as likely to undergo disease recurrence within the first 3 years after diagnosis. We show here that REST function is lost in breast cancer, at least in part via an alternative splicing mechanism. Patients with REST-less breast cancer undergo significantly more early disease recurrence than those with fully functional REST, regardless of estrogen receptor or HER2 status. Importantly, REST status may serve as a predictor of poor prognosis, helping to untangle the heterogeneity inherent in disease course and response to treatment. Additionally, the alternative splicing observed in REST

    Highly migratory marine species can travel long distances and across entire ocean basins to reach foraging and breeding grounds, yet gaps persist in our knowledge of oceanic dispersal and habitat use. This is especially true for sea turtles, whose complex life history and lengthy pelagic stage present unique conservation challenges. Few studies have explored how these young at-sea turtles navigate their environment, but advancements in satellite technology and numerical models have shown that active and passive movements are used in relation to open ocean features. Here, we provide the first study, to the best of our knowledge, to simultaneously combine a high-resolution physical forcing ocean circulation model with long-term multi-year tracking data of young, trans-oceanic North Pacific loggerhead sea turtles during their 'lost years' at sea. From 2010 to 2014, we compare simulated trajectories of passive transport with empirical data of 1-3 year old turtles released off Japan (29.7-37.5 straight carapace length cm). After several years, the at-sea distribution of simulated current-driven trajectories significantly differed from that of the observed turtle tracks. These results underscore current theories on active dispersal by young oceanic-stage sea turtles and give further weight to hypotheses of juvenile foraging strategies for this species. Such information can also provide critical geographical information for spatially explicit conservation approaches to this endangered population.

    Suboptimal weight loss (SWL) and weight regain (WR) after gastric bypass surgery (GB) remains poorly understood. This study aims to compare GB patients experiencing SWL or significant WR (SigWR) with successful controls, regarding postoperative food intake, eating behavior, physical activity (PA), and psychometrics. Forty-nine patients with >1 year post-surgery were classified as either experiencing SWL (excess body weight loss, EWL, weight regain ≥15%, n = 38), with respective control groups. Energy intake (EI) was measured with a Food Frequency Questionnaire, eating behavior using the Dutch Eating Behavior Questionnaire and the Three-Factor Eating Questionnaire, and PA using both SenseWear Armbands and the International Physical Activity Questionnaire. Eating disorders, depression, and quality of life (QoL) were measured using the Eating Disorder Examination Questionnaire, Beck Depression Inventory II, and Impact of Weight on Quality of Life, respectively. EI, macronutrient distribution, and meal frequency were similar among groups. However, disinhibited eating behavior score was higher, while most subcategories from IWQOL were significantly lower in both SWL and SigWR groups compared with their respective controls. PA was significantly lower in the SWL and SigWR groups compared with the respective controls. There were no differences between groups regarding depression. Lower PA levels, disordered eating behavior and lower QoL are associated with unsuccessful weigh loss outcome after GB surgery. Longitudinal studies are needed to clarify the potential causal relationship between the previously described variables and SWL/SigWR after GB.

  2. Tissues Use Resident Dendritic Cells and Macrophages to Maintain Homeostasis and to Regain Homeostasis upon Tissue Injury: The Immunoregulatory Role of Changing Tissue Environments

    Directory of Open Access Journals (Sweden)

    Maciej Lech

    2012-01-01

    Full Text Available Most tissues harbor resident mononuclear phagocytes, that is, dendritic cells and macrophages. A classification that sufficiently covers their phenotypic heterogeneity and plasticity during homeostasis and disease does not yet exist because cell culture-based phenotypes often do not match those found in vivo. The plasticity of mononuclear phagocytes becomes obvious during dynamic or complex disease processes. Different data interpretation also originates from different conceptual perspectives. An immune-centric view assumes that a particular priming of phagocytes then causes a particular type of pathology in target tissues, conceptually similar to antigen-specific T-cell priming. A tissue-centric view assumes that changing tissue microenvironments shape the phenotypes of their resident and infiltrating mononuclear phagocytes to fulfill the tissue's need to maintain or regain homeostasis. Here we discuss the latter concept, for example, why different organs host different types of mononuclear phagocytes during homeostasis. We further discuss how injuries alter tissue environments and how this primes mononuclear phagocytes to enforce this particular environment, for example, to support host defense and pathogen clearance, to support the resolution of inflammation, to support epithelial and mesenchymal healing, and to support the resolution of fibrosis to the smallest possible scar. Thus, organ- and disease phase-specific microenvironments determine macrophage and dendritic cell heterogeneity in a temporal and spatial manner, which assures their support to maintain and regain homeostasis in whatever condition. Mononuclear phagocytes contributions to tissue pathologies relate to their central roles in orchestrating all stages of host defense and wound healing, which often become maladaptive processes, especially in sterile and/or diffuse tissue injuries.

  4. Big Bang Day : Afternoon Play - Torchwood: Lost Souls

    CERN Multimedia

    2008-01-01

    Martha Jones, ex-time traveller and now working as a doctor for a UN task force, has been called to CERN where they're about to activate the Large Hadron Collider. Once activated, the Collider will fire beams of protons together recreating conditions a billionth of a second after the Big Bang - and potentially allowing the human race a greater insight into what the Universe is made of. But so much could go wrong - it could open a gateway to a parallel dimension, or create a black hole - and now voices from the past are calling out to people and scientists have started to disappear... Where have the missing scientists gone? What is the secret of the glowing man? What is lurking in the underground tunnel? And do the dead ever really stay dead? Lost Souls is a spin-off from the award-winning BBC Wales TV production Torchwood. It stars John Barrowman, Freema Agyeman, Eve Myles, Gareth David-Lloyd, Lucy Montgomery (of Titty Bang Bang) and Stephen Critchlow.

    We show that partial recovery of the entanglement lost in a bipartite pure state entanglement transformations is almost always possible irrespective of the dimension. Let $\\ket{\\psi}$ and $\\ket{\\vph}$ be $n\\times n$ states and $\\ket{\\psi} \\longrightarrow \\ket{\\vph}$ under local operations. We ask whether there exists $k\\times k$ states, $\\ket{\\chi}$ and $\\ket{\\omega}$, $k E(\\ket{\\chi})$, $E$ being the entropy of entanglement such that $\\ket{\\psi}\\otimes\\ket{\\chi} \\longrightarrow \\ket{\\vph}\\otimes\\ket{\\omega}$ under LOCC. We show that for almost all pairs of comparable states recovery is achievable by $2\\times 2$ states, no matter how large the dimension of the parent states are. For other cases we show that the dimension of the auxiliary entangled state depends on the presence of equalities in the majorization relations of the parent states. We identify those states and show that recovery is still possible using states in $k\\times k$, $2

    Research accounts of the struggle of professions to attain and maintain a monopoly, strategies of exclusion and usurpation, make for interesting and often exciting reading. The purpose of this article is to present a less frequently reported phenomenon--the study of a profession that had a monopoly, and then lost it. The authors attempt to answer the question: under what circumstances will a profession support the state in breaking their own monopoly? The study looked at the pharmacy profession in Iceland in the light of the recent change in drug legislation. Interviews with key actors in the pharmacy profession were conducted to gain an understanding of how they interpreted and experienced this change. Three factors contributed to the break in the professional monopoly: (1) political desire to take advantage of new competition and deregulation policy, (2) desire to cut the health budget and (3) internal divisions within the profession. The results of the study revealed at least four internal divisions within the pharmacy profession: (1) urban/rural, (2) employer/employee, (3) lower/higher education and (4) young/old. The article illustrates how a profession weakened by internal strife became prey to the government's cost cutting activities. This study is an example of how internal conflicts not only weakened the profession, but created a climate conducive to losing its monopoly. Our findings raise fundamental questions about the future of professions in society today.

    The Global Polio Eradication Initiative was aimed to eradicate poliomyelitis by the year 2000, however, polio eradication is still not in sight even in 2010, over 10 years after the initial target date. In 2010, indigenous transmission of wild polioviruses has been interrupted throughout the world except four countries, Afghanistan, Pakistan, India, and Nigeria. Despite the intense use of monovalent oral polio vaccines, type 1 and type 3 wild polioviruses still circulate in the four remaining polio-endemic countries, and multiple importations of wild polioviruses have also occurred extensively from Nigeria and India to a number of previously polio-free countries in Africa, Asia, and Europe. Furthermore, the emergence of type 2 vaccine-derived polioviruses has raised concerns about low level of immunity against type 2 poliovirus in some polio-endemic areas like Nigeria and India. On the other hand, operational improvements in 2009 were reported in high-risk states in northern Nigeria and transmission of type 1 and type 3 polioviruses in Nigeria is markedly declining from 2009 to 2010. Moreover, bivalent oral polio vaccine containing Sabin 1 and Sabin 3 strains has been introduced in 2010 as a promising tool to improve and simplify the supplemental immunization activities in high-risk areas. Although there was no apparent decline in the annual number of polio cases in 2000-2009 globally, it would be critical to review our experience during "the lost decade of global polio eradication" to move forward into the final stage of global polio eradication.

    In 1970, the Soviet Lunokhod 1 rover delivered a French-built laser reflector to the Moon. Although a few range measurements were made within three months of its landing, these measurements---and any that may have followed---are unpublished and unavailable. The Lunokhod 1 reflector was, therefore, effectively lost until March of 2010 when images from the Lunar Reconnaissance Orbiter (LRO) provided a positive identification of the rover and determined its coordinates with uncertainties of about 100 m. This allowed the Apache Point Observatory Lunar Laser-ranging Operation (APOLLO) to quickly acquire a laser signal. The reflector appears to be in excellent condition, delivering a signal roughly four times stronger than its twin reflector on the Lunokhod 2 rover. The Lunokhod 1 reflector is especially valuable for science because it is closer to the Moon's limb than any of the other reflectors and, unlike the Lunokhod 2 reflector, we find that it is usable during the lunar day. We report the selenographic positi...

    Studies concerning marine litter have received great attention over the last several years by the scientific community mainly due to their ecological and economic impacts in marine ecosystems, from coastal waters to the deep ocean seafloor. The distribution, type and abundance of marine litter in Ormonde and Gettysburg, the two seamounts of Gorringe Bank, were analyzed from photo and video imagery obtained during ROV-based surveys carried out at 60-3015 m depths during the E/V Nautilus cruise NA017. Located approximately 125 nm southwest of Portugal, Gorringe Bank lays at the crossroad between the Atlantic and the Mediterranean and is therefore characterized by an intense maritime traffic and fishing activities. The high frequency of lost or discarded fishing gear, such as cables, longlines and nets, observed on Gorringe Bank suggests an origin mostly from fishing activities, with a clear turnover in the type of litter (mostly metal, glass and to a much lesser extent, plastic) with increasing depth. Litter was more abundant at the summit of Gorringe Bank (ca. 4 items·km- 1), decreasing to less than 1 item·km- 1 at the flanks and to ca. 2 items·km- 1 at greater depths. Nevertheless, litter abundance appeared to be lower than in continental margin areas. The results presented herein are a contribution to support further actions for the conservation of vulnerable habitats on Gorringe Bank so that they can continue contributing to fishery productivity in the surrounding region.

  10. Effect of Foamed Pattern Density on the Lost Foam Process

    2007-07-01

    Full Text Available The study examines the effect of the foamed polystyrene pattern density on the process of making castings by the lost foam technique with emphasis put on the analysis of simulation tests. The simulation regarded the effect that pattern density is said to have on the mould cavity filling rate, pressure in the gas gap, and size of this gap. For simulation tests of the full mould process, a mathematical model presented in this study was used. For calculations, the author's own algorithm was applied. The investigations have proved that with decreasing pattern density the pouring rate increases, while pressure in the gas gap and the size of the gap are decreasing. The increasing pouring rate ensures correct making of castings, even if their shapes are very intricate and the wall cross-sections are very small. Smaller size of the gas gap and lower pressure of gases in this gap reduce the risk of mould damage. The author’s own investigations have proved a very significant effect of the density of foamed polystyrene pattern on the casting process, and specially on the mould pouring rate. The best pouring rate is ensured by patterns of the density comprised in a range of ρ2 =18÷25 kg/m3.

  11. Index of years of potential life lost in Mexico.

    1990-01-01

    The index of years of potential life lost (IYPL) is calculated for the states of Mexico in comparison to that of Mexico as a whole. Based on deaths notified in 1985, standardized reasons for mortality and the IYPL were calculated for 5-year cohorts in 32 Mexican states. The IYPL was first calculated for the State of Aguascalientes, a small state in central Mexico, using the formula of Haenszel and Yerushalmy. Columns were generated showing 1) the middle point for each cohort, by calculating the semi-sum of the relative limits in each age category; 2) number of deaths subtracted from an arbitrary life expectancy of 70; 3) population of each cohort; 4) rate of general mortality for each cohort; 5) expected deaths the state had a mortality equal to the Mexican Republic; and 6) IYPL. Results for IYPL for all the Mexican states are tabulated, next to life expectancy, and standardized reason for mortality. The results are also plotted graphically on maps. While at first the 2 figures do not seem consistent, socioeconomic factors such as child mortality, occupational mortality, nutrition, and environmental sanitation can explain some of the discrepancies. Usually mortality rates and life expectancy are used to describe and compare health in different regions. IYPL has it uses, despite its simple calculation, because it can suggest ways to allocate resources according to health needs.

  12. Identifying the lost generation of adults with autism spectrum conditions.

    Lai, Meng-Chuan; Baron-Cohen, Simon

    2015-11-01

    Autism spectrum conditions comprise a set of early-onset neurodevelopmental syndromes with a prevalence of 1% across all ages. First diagnosis in adulthood has finally become recognised as an important clinical issue due to the increasing awareness of autism, broadening of diagnostic criteria, and the introduction of the spectrum concept. Thus, the idea of a lost generation of people who were previously excluded from a diagnosis of classic autism has arisen. Making a first diagnosis of autism spectrum conditions in adults can be challenging for practical reasons (eg, no person to provide a developmental history), developmental reasons (eg, the acquisition of learnt or camouflaging strategies), and clinical reasons (eg, high frequency of co-occurring disorders). The diagnostic process includes referral, screening, interviews with informants and patients, and functional assessments. In delineating differential diagnoses, true comorbidities, and overlapping behaviour with other psychiatric diagnoses, particular attention should be paid to anxiety, depression, obsessive-compulsive disorder, psychosis, personality disorders, and other neurodevelopmental disorders. Possible misdiagnosis, especially in women, should be explored. The creation of supportive, accepting, and autism-friendly social and physical environments is important and requires a coordinated effort across agencies and needs support from government policies.

    Full Text Available Microstructure and mechanical properties of lost foam cast aluminum alloys have been investigated in both primary A356 (0.13% Fe and secondary 356 (0.47%. As expected, secondary 356 shows much higher content of Fe-rich intermetallic phases, and in particular the porosity in comparison with primary A356. The average area percent and size (length of Fe-rich intermetallics change from about 0.5% and 6 祄 in A356 to 2% and 25 祄 in 356 alloy. The average area percent and maximum size of porosity also increase from about 0.4% and 420 祄 to 1.4% and 600 祄, respectively. As a result, tensile ductility decreases about 60% and ultimate tensile strength declines about 8%. Lower fatigue strength was also experienced in the secondary 356 alloy. Low cycle fatigue (LCF strength decreased from 187 MPa in A356 to 159 MPa in 356 and high cycle fatigue (HCF strength also declined slightly from 68 MPa to 64 MPa.

    1997-04-01

    Mathematical models of the human thermoregulatory system have been used to make predictions of the likely survival of divers in a ``lost bell`` who can be exposed to very low ambient temperatures. The circumstances considered are not the most extreme but those where, partly by shivering, the individual can re-enter thermal balance. The ability accurately to predict the level and duration of metabolic heat production is critical for the estimation of survival time under these conditions. Limitations on the accuracy of current models arise from the lack of precision in modelling the intensity and duration of the metabolic (shivering) response. A different basis for predicting shivering endurance using the time to hypogylcaemia (blood glucose level less than 2.5 mmol/1) is proposed. This leads to predicted survival times ranging from 10 to over 24 hours for those individuals able to stabilise deep body temperature. This seems to be more consistent with the limited experimental data which exists than the 8-9 hours predicted by other models. In order to help maintain blood sugar levels, and hence metabolic heat production, it is recommended that emergency rations within bells should provide 500g of carbohydrate a day.

    Burklo, Daniel A.

    While the United States has always been a global leader in the innovation of science and technology, this leading global position is in jeopardy. As other developing countries produce intellectual capital in the form of engineers at increasing rates, the country will continue to lose ground. Today the need for the country to produce engineers is greater than ever before. Recognizing this need, attempts have been made to increase entrance into engineering fields in higher education by providing STEM (science, technology, engineering, and mathematics) activities during K-12 education. While STEM initiatives create awareness and interest, this study investigates what actually motivates individuals to choose engineering programs in higher education. A quantitative study utilizing survey results from 202 first year engineering students in the state of Ohio illustrates what has motivated them to choose engineering as a major. The study examines who, when, and what motivated the students to choose engineering by examining the relationship of influential people and STEM initiatives participated in during their K-12 education to enrollment in engineering programs at colleges and universities in the state of Ohio. The study proved the general hypothesis that there are influential people in an individual's college choice, such as the parent, and there are time periods during K-12 education when individuals are more motivated, such as the high school years. The study also showed a positive correlation between the motivation toward engineering programs and the number of STEM opportunities in which individuals participated yet there was little difference when comparing the different types of STEM initiatives.

    Theoretical Models for the shaping of PNe are reviewed in light of new high resolution images. The new data indicate the purely hydrodynamic interacting stellar winds model can not recover the full variety of shapes and kinematics. New models, some speculative, others more firmly grounded are discussed. In particular, accretion disks and magnetic fields are identified as two of the most promising avenues of future research. Outstanding issues such as jet formation by PNe disks and dynamo activity in P-AGB stars remain to studied. Finally, new simulations of the Egg Nebula are presented as an example of a ``paleontological'' study designed to recover the history of an individual object.

    2004-03-01

    The peculiar biogeography of the so-called "Lost World", i.e. the summits of sandstone tableaux ( tepuis) in the Neotropical Guyana region of Venezuela, has generated a debate regarding the factors that are thought to account for modern vegetation patterns in the region. Some argue that plant communities on these high-elevation summits reflect a long history of evolution in isolation, while others surmise that there has been substantial biotic interchange with the surrounding lowlands during glacial times. Until now, these apparently competing hypotheses have not been tested using palaeoecological methods. I used pollen analysis of Quaternary sediments and documented past vertical migrations of vegetation in response to climate changes, which supports the second hypothesis. Physiographical analysis, however, shows that about half the tableaux summits are too high for their flora to have reached the lowlands during the last glaciation, suggesting that a portion of the tableaux vegetation has always experienced some degree of biotic isolation. Thus, a component of the summit vegetation evolved in isolation, whereas other taxa experienced interchange, as reflected in endemism patterns among the tableaux summits. Biogeographical patterns on the summits are the result of complex evolutionary processes. The two hypotheses invoked to explain the vegetation patterns are not mutually exclusive, but instead complement one another.

    Grounded theory, first developed by Glaser and Strauss in the 1960s, was introduced into nursing education as a distinct research methodology in the 1970s. The theory is grounded in a critique of the dominant contemporary approach to social inquiry, which imposed "enduring" theoretical propositions onto study data. Rather than starting from a set theoretical framework, grounded theory relies on researchers distinguishing meaningful constructs from generated data and then identifying an appropriate theory. Grounded theory is thus particularly useful in investigating complex issues and behaviours not previously addressed and concepts and relationships in particular populations or places that are still undeveloped or weakly connected. Grounded theory data analysis processes include open, axial and selective coding levels. The purpose of this article was to explore the grounded theory research process and provide an initial understanding of this methodology.

    Some living kidney donors report lost income during recovery from surgery. Little is known about whether concern for living donor's lost income affects the decision to undergo donation evaluation and the willingness of transplant candidates to discuss living kidney donation (LKD) with others. To examine whether transplant patients were told by potential donors about lost income concerns and whether patients chose not to discuss LKD with others due to lost income concerns. Kidney transplant patients (185 wait-listed candidates, 171 deceased donor recipients, and 100 live donor recipients) at 2 centers completed a questionnaire to assess whether concern about donor's lost income was a consideration in discussion about LKD with others. One-third (32%) were told by a family member/friend that they were willing to donate but were concerned about potential lost income. The majority of those who expressed financial concern (64%) did not initiate donation evaluation. Many patients (42%) chose not to discuss living donation with a family member/friend due to concern about the impact of lost income on the donor. In the multivariable model, lower annual household income was the only statistically significant predictor of both having a potential donor expressing lost income concern and choosing not to talk to someone because of lost income concern. Findings from the current study underscore how concern about income loss for living donors may affect decision-making by both transplant candidates and potential donors.

    Approximately 50 % of all acromegalic patients will require lifelong medical treatment to normalize mortality rates and reduce morbidity. Thus, adherence to therapy is essential to achieve treatment goals. To date, no study has evaluated the frequency and reasons for loss to follow-up in the acromegalic population. The current study aimed at evaluating the frequency of acromegalic patient loss to follow-up in three reference centers and the reasons responsible for their low compliance with treatment. All of the files for the acromegalic patients in the three centers were reviewed. Those patients, who had not followed up with the hospital for more than a year, were contacted via phone and/or mail and invited to participate. Patients who agreed to participate were interviewed, and blood samples were collected. A total of 239 files were reviewed; from these 42 patients (17.6 %) were identified who were lost to follow-up. It was possible to contact 27 of these patients, 10 of whom did not attend the appointments for more than one time and 17 of whom agreed to participate in the study. Fifteen of these 17 patients had active disease (88.2 %), and all of the patients restarted treatment in the original centers. The main reason for loss to follow-up was an absence of symptoms. High-quality follow-up is important in acromegaly to successfully achieve the aims of the treatment. An active search for patients may allow the resumption of treatment in a significant proportion of these cases, contributing to reduced morbidity and mortality in this patient population.

    The lost foam casting (LFC) process is emerging as a reliable casting method. The metal-fill profile in LFC plays an important role among several factors that affect casting quality. The metal-fill profile is in turn affected by several factors. Several casting defects may result due to an improper metal-fill process. Hence, it becomes essential to characterize and control, if possible, the metal-fill process in LFC. This research presents instrumentation and a technique to monitor and characterize the metal-fill process. The characterization included the determination of the position of the metal front and the profile in which the metal fills up the foam pattern. The instrumentation included capacitive sensors. Each sensor is comprised of two electrodes whose capacitive coupling changes as the metal fills the foam pattern. Foundry tests were conducted to obtain the sensors' responses to the metal fill. Two such sensors were used in the foundry tests. Data representing the responses of these sensors during the metal-fill process were collected using a data acquisition system. A number of finite element electrostatic simulations were carried out to study the metal-fill process under conditions similar to those experienced in foundry tests. An artificial neural network was trained using the simulation data as inputs and the corresponding metal-fill profiles as outputs. The neural network was then used to infer the profile of the metal-fill during foundry tests. The results were verified by comparing the metal-fill profile inferred from the neural network to the actual metal-fill profile captured by an infrared camera used during the foundry tests. The match up between the inferred profiles and the infrared camera measurements was satisfactory, indicating that the developed technique provides a reliable and cost effective method to monitor the metal-fill profile in LFC.

    Weight loss induces compensatory biological adjustments that increase hunger and decrease resting metabolic rate (RMR), which increase propensity for weight regain. In non-obese adults high levels of physical activity coupled with high energy intake (high energy flux) are associated with higher RMR and reduced hunger. We tested the possibility that a high flux state attenuates the increase in hunger and the decrease in RMR characteristic of diet-induced weight loss. Six obese adults [age (mean ± SE) = 42 ± 12 y; body mass index (BMI) = 35.7 ± 3.7 kg/m(2)] underwent measures of RMR, the thermic effect of a meal (TEM), and fasting and postprandial measures of hunger and fullness as well as plasma glucose and insulin. Following weight loss, subjects completed two 5-day conditions of energy balance in random order-Low Flux (LF): sedentary with energy intake (EI) = RMR (kcal/d) × 1.35; and High Flux (HF): net exercise energy cost of ∼500 kcal/d and EI = RMR (kcal/d) × 1.7. RMR was measured daily for each flux condition. The morning following each of the respective experimentally controlled HF and LF conditions (flux day 5), they underwent the same pre-weight loss tests and also reported their perceptions of hunger and fullness during the previous four days of HF and LF, respectively. Average daily RMR was higher during HF (1926 ± 138 kcal/day) compared to LF (1847 ± 126 kcal/day; P weight loss, compared to a sedentary LF state of energy balance, a short-term HF energy balance state is associated with higher RMR, lower perceived hunger, and greater perceived fullness, all of which could help attenuate the biologic drive to regain weight. Given the pilot nature of this study and the relatively short period of time spent in the high and low flux states, future research is needed to address this research question in a larger sample over a longer time period.

    Reoperative surgery for the morbidly obese has become increasingly common due to postoperative weight regain. There are limited studies evaluating the effectiveness of revisional surgery. This study evaluates the weight loss outcomes of revisional surgery over a 2-year period at our University Hospital, USA. Of the 412 patients who underwent laparoscopic bariatric surgery between June 2009 and June 2011, we identified 25 patients who had Roux-en-Y gastric bypass (RYGB) originally, who underwent laparoscopic revisional surgery for weight regain. Preoperative and postoperative data were reviewed. Statistical analysis was performed using paired t test. This study includes 0 male and 25 female patients with an average age of 42 (range min to max: 28-58), mean original body mass index (BMI) of 54.6 kg/m(2) (r = 37.3-80.7), average lowest BMI achieved of 32.2 (r = 20.1-50.9), and average BMI at the time of revision of 41.0 kg/m(2) (r = 29.5-60.7, standard deviation (SD) = 8.5). All laparoscopic revisions consisted of resizing the gastric pouch by resection and recreating the gastrojejunostomy. Average hospital length of stay was 1.28 days (r = 1-4). Perioperative morbidity was 8 %; one patient developed a trocar site hernia which required repair, and another suffered postoperative bleeding requiring transfusion. There was no mortality. Postoperative BMI averages at 3, 6, 9, 12, and 24 months were 35.0 (SD = 7.15), 34.7 (SD = 4.26), 36.2 (SD = 7.63), 33.0 (SD = 6.58), and 44.2 (SD = 12.87), respectively. Statistically significant weight loss was achieved at 3 [t (10) = 6.74, p weight loss at 24 months postoperatively [t (4) = -0.16, p > 0.05]. Laparoscopic revisional bariatric surgery can be performed with significant weight loss up to 1 year postoperatively. However, additional studies are required to evaluate longer-term success.

    Aims: The aim of this paper is to find lost siblings of the Sun by analyzing high resolution spectra. Finding solar siblings will enable us to constrain the parameters of the parental cluster and the birth place of the Sun in the Galaxy. Methods: The solar siblings can be identified by accurate measurements of metallicity, stellar age and elemental abundances for solar neighbourhood stars. The solar siblings candidates were kinematically selected based on their proper motions, parallaxes and colours. Stellar parameters were determined through a purely spectroscopic approach and partly physical method, respectively. Comparing synthetic with observed spectra, elemental abundances were computed based on the stellar parameters obtained using a partly physical method. A chemical tagging technique was used to identify the solar siblings. Results: We present stellar parameters, stellar ages, and detailed elemental abundances for Na, Mg, Al, Si, Ca, Ti, Cr, Fe, and Ni for 32 solar sibling candidates. Our abundances analysis shows that four stars are chemically homogenous together with the Sun. Technique of chemical tagging gives us a high probability that they might be from the same open cluster. Only one candidate - HIP 40317 - which has solar metallicity and age could be a solar sibling. We performed simulations of the Sun's birth cluster in analytical Galactic model and found that most of the radial velocities of the solar siblings lie in the range -10 ≤ Vr ≤ 10 km s-1, which is smaller than the radial velocity of HIP 40317 (Vr = 34.2 km s-1), under different Galactic parameters and different initial conditions of the Sun's birth cluster. The sibling status for HIP 40317 is not directly supported by our dynamical analysis. Based on observations made with Nordic Optical Telescope at La Palma under programme 44-014.

  13. Communication, concepts and grounding.

    van der Velde, Frank

    2015-02-01

    This article discusses the relation between communication and conceptual grounding. In the brain, neurons, circuits and brain areas are involved in the representation of a concept, grounding it in perception and action. In terms of grounding we can distinguish between communication within the brain and communication between humans or between humans and machines. In the first form of communication, a concept is activated by sensory input. Due to grounding, the information provided by this communication is not just determined by the sensory input but also by the outgoing connection structure of the conceptual representation, which is based on previous experiences and actions. The second form of communication, that between humans or between humans and machines, is influenced by the first form. In particular, a more successful interpersonal communication might require forms of situated cognition and interaction in which the entire representations of grounded concepts are involved.

    Strong earthquake ground motion records are fundamental in engineering applications. Ground motion time series are used in response-history dynamic analysis of structural or geotechnical systems. In such analysis, the validity of predicted responses depends on the validity of the input excitations. Ground motion records are also used to develop ground motion prediction equations(GMPEs) for intensity measures such as spectral accelerations that are used in response-spectrum dynamic analysis. Despite the thousands of available strong ground motion records, there remains a shortage of records for large-magnitude earthquakes at short distances or in specific regions, as well as records that sample specific combinations of source, path, and site characteristics.

  15. Ground energy coupling

    Metz, P. D.

    The feasibility of ground coupling for various heat pump systems was investigated. Analytical heat flow models were developed to approximate design ground coupling devices for use in solar heat pump space conditioning systems. A digital computer program called GROCS (GRound Coupled Systems) was written to model 3-dimensional underground heat flow in order to simulate the behavior of ground coupling experiments and to provide performance predictions which have been compared to experimental results. GROCS also has been integrated with TRNSYS. Soil thermal property and ground coupling device experiments are described. Buried tanks, serpentine earth coils in various configurations, lengths and depths, and sealed vertical wells are being investigated. An earth coil used to heat a house without use of resistance heating is described.

    This study sought to explore English-speaking therapists' experiences of providing stroke rehabilitation to non-English speaking individuals in an urban area. This was a qualitative study using focus groups. Two focus groups were conducted. Participants included physiotherapists, occupational therapists, speech and language therapists and a psychotherapist (n = 13). A grounded theory approach was used to analyse data. Factors affecting rehabilitation were categorised under themes of engagement, practicalities and social context. Subtle communication was identified as a core category that ran through all themes, illustrating therapists' use and interpretation of subtleties and nuances which a language barrier impeded. Providing rehabilitation across a language barrier was found to present significant challenges. Therapists perceived that assessment and treatment are likely to be delayed and limited in scope, especially regarding cognition and neurological communication disorders. A conceptual model of factors involved in rehabilitation across a language barrier was generated. Therapists perceive that rehabilitation is affected by a language barrier. The conceptual model illustrates the interrelationship between factors affecting rehabilitation provision when there is a language barrier. Subtle communication was found to be an important therapeutic tool which was lost across a language barrier, and may have broader relevance to therapeutic relationships in the field of rehabilitation. Further research is needed to gain insights into experiences of individuals receiving rehabilitation across a language barrier and to identify how to enhance the efficacy of rehabilitation for them. As it appears rehabilitation is affected by a language barrier, this is likely to impact on the outcome of an individual's rehabilitation. The concept of "subtle communication" should be recognised as a vital component of therapeutic skills. Improving access to formal interpreters

  18. Assessment of net lost revenue adjustment mechanisms for utility DSM programs

    Energy Technology Data Exchange (ETDEWEB)

    Baxter, L.W.

    1995-01-01

    Utility shareholders can lose money on demand-side management (DSM) investments between rate cases. Several industry analysts argue that the revenues lost from utility DSM programs are an important financial disincentive to utility DSM investment. A key utility regulatory reform undertaken since 1989 allows utilities to recover the lost revenues incurred through successful operation of DSM programs. Explicitly defined net lost revenue adjustment (NLRA) mechanisms are states` preferred approach to lost revenue recovery from DSM programs. This report examines the experiences states and utilities are having with the NLRA approach. The report has three objectives. First, we determine whether NLRA is a feasible and successful approach to removing the lost-revenue disincentive to utility operation of DSM programs. Second, we identify the conditions linked to successful implementation of NLRA mechanisms in different states and assess whether NLRA has changed utility investment behavior. Third, we suggest improvements to NLRA mechanisms. We first identify states with NLRA mechanisms where utilities are recovering lost revenues from DSM programs. We interview staff at regulatory agencies in all these states and utility staff in four states. These interviews focus on the status of NLRA, implementation issues, DSM measurement issues, and NLRA results. We also analyze regulatory agency orders on NLRA, as well as associated testimony, reports, and utility lost revenue recovery filings. Finally, we use qualitative and quantitative indicators to assess NLRA`s effectiveness. Contrary to the concerns raised by some industry analysts, our results indicate NLRA is a feasible approach to the lost-revenue disincentive.

    Full Text Available Abstract Background Incomplete ascertainment of outcomes in randomized controlled trials (RCTs is likely to bias final study results if reasons for unavailability of patient data are associated with the outcome of interest. The primary objective of this study is to assess the potential impact of loss to follow-up on the estimates of treatment effect. The secondary objectives are to describe, for published RCTs, (1 the reporting of loss to follow-up information, (2 the analytic methods used for handling loss to follow-up information, and (3 the extent of reported loss to follow-up. Methods We will conduct a systematic review of reports of RCTs recently published in five top general medical journals. Eligible RCTs will demonstrate statistically significant effect estimates with respect to primary outcomes that are patient-important and expressed as binary data. Teams of 2 reviewers will independently determine eligibility and extract relevant information from each eligible trial using standardized, pre-piloted forms. To assess the potential impact of loss to follow-up on the estimates of treatment effect we will, for varying assumptions about the outcomes of participants lost to follow-up (LTFU, calculate (1 the percentage of RCTs that lose statistical significance and (2 the mean change in effect estimate across RCTs. The different assumptions we will test are the following: (1 none of the LTFU participants had the event; (2 all LTFU participants had the event; (3 all LTFU participants in the treatment group had the event; none of those in the control group had it (worst case scenario; (4 the event incidence among LTFU participants (relative to observed participants increased, with a higher relative increase in the intervention group; and (5 the event incidence among LTFU participants (relative to observed participants increased in the intervention group and decreased in the control group.

    With the increased emphasis on vehicle weight reduction, production of near-net shape components by lost foam casting will make significant inroad into the next-generation of engineering component designs. The lost foam casting process is a cost effective method for producing complex castings using an expandable polystyrene pattern and un-bonded sand. The use of un-bonded molding media in the lost foam process will impose less constraint on the solidifying casting, making hot tearing less prevalent. This is especially true in Al-Mg and Al-Cu alloy systems that are prone to hot tearing when poured in rigid molds partially due to their long freezing range. Some of the unique advantages of using the lost foam casting process are closer dimensional tolerance, higher casting yield, and the elimination of sand cores and binders. Most of the aluminum alloys poured using the lost foam process are based on the Al-Si system. Very limited research work has been performed with Al-Mg and Al-Cu type alloys. With the increased emphasis on vehicle weight reduction, and given the high-strength-to-weight-ratio of magnesium, significant weight savings can be achieved by casting thin-wall (≤ 3 mm) engineering components from both aluminum- and magnesium-base alloys.

    2012-01-01

    Designing and optimizing cost functions and energy landscapes is a problem encountered in many fields of science and engineering. These landscapes and cost functions can be embedded and annealed in experimentally controllable spin Hamiltonians. Using an approach based on group theory and symmetries, we examine the embedding of Boolean logic gates into the ground state subspace of such spin systems. We describe parameterized families of diagonal Hamiltonians and symmetry operations which preserve the ground state subspace encoding the truth tables of Boolean formulas. The ground state embeddings of adder circuits are used to illustrate how gates are combined and simplified using symmetry. Our work is relevant for experimental demonstrations of ground state embeddings found in both classical optimization as well as adiabatic quantum optimization.

  13. Regaining our humanity through story.

    2007-01-01

    In this issue of Innovations in Integrative Healthcare Education, we are departing from our usual format of spotlighting specific projects or programs in lieu of presenting a more extended piece by MacKenzie on relationship-centered care and narrative medicine. The importance of these topics cannot be overestimated in their role of humanizing the healthcare encounter, improving self-awareness of the practitioner, and creating a space in which the patient feels deeply listened to. A commentary by Dr Michelle Sierpina is also included in this special section to put into context the power of narrative in medicine and in patients' lives. Her recent PhD focused on the power of life stories told by seniors; that research and training enables her to provide a broad and scholarly review of the power of story in relation to MacKenzie's article. In the medical school at University of Texas Medical Branch, we send out first-year medical students in the first couple of months of the first semester to patients' homes to just get their story, not a medical history, as part of a required course on the practice of medicine. Many students find this immensely anxiety provoking, due to the lack of structure and familiar context. However, ultimately they find an opportunity to encounter a real person in a nonclinical setting. A scoring rubric based on the construction and quality of a short story allows us to grade the students objectively. However, a most interesting finding, which we expect to present at the Ottawa Conference in Australia next spring, is the process of personal transformation that such story writing has for students. This is also reported by MacKenzie in her article and in Sierpina's accompanying commentary. The importance of capturing and understanding the patient's story is also a major focus in nurse practitioner programs across the United States, where the art of listening and the importance of patient narratives have long been emphasized. In an integrative assessment of patients, we "make a history" rather than "take a history." This means that we coconstruct with the patient the reality of the medical encounter and the tone and timbre of the healing relationship. By bringing our own culture, beliefs, and values to the exam room and then allowing the patient to share theirs with us, we create a new kind of relationship-centered, patient-centered care model. This allows the strength of the linear standard medical history, chief complaint, history of present illness, past history, social/family history, review of systems, etc, to be informed and enriched by the nonlinear, perhaps circular, patient story. This story making further allows deeper exploration of the patient's life goals as well as their medical goals.(1) It creates increased personalization of the provider-patient relationship and moves from the "I-them" to Buber's "I-thou." Enjoy the article and the accompanying commentary and consider how to implement this kind of care and mindfulness into the education of health professional students and your practice.

  14. The impact of pre-treatment weight-loss expectations on weight loss, weight regain, and attrition in people who are overweight and obese: a systematic review of the literature.

    2012-09-01

     Research exploring the relationships between initial weight-loss expectations with actual outcome in terms of weight loss, weight regain, and attrition/attendance suggests contradictory findings. The purpose of this review was to collate research exploring the impact of weight-loss expectations on weight loss, weight regain, and attendance/attrition. It was hoped this would further the current understanding of the relationship between expectations and outcome.  PsychInfo, Medline, and Web of Science were systematically searched and 13 relevant papers were identified. To be included for review, studies had to assess and analyse weight-related expectations; distinguish between higher and lower expectations; include participants who were aged over 18 and attempting to lose weight; be published within a peer-reviewed journal between 1990 and 2010. Findings were analysed qualitatively.  Findings were largely unclear. The relationship between expectations and weight loss appears to change with time, whilst the findings from studies looking at weight regain suggest that there is no association. The relationship between expectations with attendance/attrition is also unclear.  Through reviewing literature regarding the relationships between expectations with various outcomes, a number of discrepancies emerged. Exploration of these discrepancies enabled an understanding to be developed of the complex relationship between expectations and weight-loss treatment outcome. The importance of the terminology used and the ways in which expectations are assessed is discussed and future areas of research are suggested. © 2011 The British Psychological Society.

  18. Density and Mechanical Properties of Aluminum Lost Foam Casting by Pressurization during Solidification

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    Porosity is thought to be severe in aluminum alloy castings produced by lost foam process due to the pyrolysis of the polystyrene foam pattern during pouring, which results in detrimental effect in mechanical property.The slow solidification rate promotes the formation of gassing pin holes, and relative weakness of the thermal gradients can cause micro-shrinkage if the outline of the part complicates feeding in the lost foam casting. One of the methods to eliminate the porosity is to apply high pressure to the molten metal like an isostatic forging during solidification. Fundamental experiments were carried out to evaluate the effect of the external pressure on the porosity and mechanical properties of A356.2 alloy bar in the lost foam casting. Solidification time and porosity decreased with increasing the applied pressure during solidification. Applying external pressure was effective in decreasing the porosity and increasing the elongation of the lost foam casting.

    One of the first requisites for the intelligent planning of utilization and control of water and for the administration of laws relating to its use is data on the quantity, quality, and mode of occurrence of the available supplies. The collection, evaluation and interpretation, and publication of such data are among the primary functions of the U.S. Geological Survey. Since 1895 the Congress has made appropriations to the Survey for investigation of the water resources of the Nation. In 1929 the Congress adopted the policy of dollar-for-dollar cooperation with the States and local governmental agencies in water-resources investigations of the U.S. Geological Survey. In 1937 a program of ground-water investigations was started in cooperation with the Oklahoma Geological Survey, and in 1949 this program was expanded to include cooperation with the Oklahoma Planning and Resources Board. In 1957 the State Legislature created the Oklahoma Water Resources Board as the principal State water agency and it became the principal local cooperator. The Ground Water Branch of the U.S. Geological Survey collects, analyzes, and evaluates basic information on ground-water resources and prepares interpretive reports based on those data. Cooperative ground-water work was first concentrated in the Panhandle counties. During World War II most work was related to problems of water supply for defense requirements. Since 1945 detailed investigations of ground-water availability have been made in 11 areas, chiefly in the western and central parts of the State. In addition, water levels in more than 300 wells are measured periodically, principally in the western half of the State. In Oklahoma current studies are directed toward determining the source, occurrence, and availability of ground water and toward estimating the quantity of water and rate of replenishment to specific areas and water-bearing formations. Ground water plays an important role in the economy of the State. It is

    For Asian immigrants, immigration has the potential to disrupt all familiar routines. That is a threat to their health and well-being. This grounded theory study explored how immigrants adjust to a new environment by analyzing the experiences of 25 Korean immigrants in New Zealand. The findings suggest that immigration is a stress-inducing phenomenon that requires adjustment of valued activities and adversely affects their health. In response, participants worked on regaining control over disrupted activities by opting for two world perspectives. The study helps social workers to develop effective interventions and services for immigrants to better handle health problems.

  11. Grounding Anger Management

    Directory of Open Access Journals (Sweden)

    Odis E. Simmons, PhD

    2017-06-01

    Full Text Available One of the things that drew me to grounded theory from the beginning was Glaser and Strauss’ assertion in The Discovery of Grounded Theory that it was useful as a “theoretical foothold” for practical applications (p. 268. From this, when I was a Ph.D student studying under Glaser and Strauss in the early 1970s, I devised a GT based approach to action I later came to call “grounded action.” In this short paper I’ll present a very brief sketch of an anger management program I developed in 1992, using grounded action. I began my research by attending a two-day anger management training workshop designed for training professionals in the most commonly used anger management model. Like other intervention programs I had seen, this model took a psychologizing and pathologizing approach to the issue. Following this, I sat through the full course of an anger management program that used this model, observing the reactions of the participants and the approach of the facilitator. Following each session I conducted open-ended interviews with most of the participants, either individually or in groups of two or three. I had also done previous research in counseling and social work contexts that turned out to be very relevant to an anger management program design.

    There is hardly any information regarding years of life lost due to cancer in Colombia. To quantify total and average years of life lost due to cancer in Colombia, and to investigate changes in this burden between 1997 and 2012. We obtained sex-specific data on age distribution, remaining life expectancy, deaths due to specific cancers and total number of deaths from the Colombian Departamento Administrativo Nacional de Estadísticas. We calculated years of life lost based on each individual´s age at death and the remaining life expectancy at that age; as for average years of life, we divided these by the number of deaths due to specific cancers. The total number of cancer deaths increased by 33% between 1997 and 2012, comprising 15% of male and 20% of female deaths in the period 2010-2012. Total years of life lost due to cancer increased by 25.1% for males and 31.1% for females over the study period. The highest increases (>40%) were observed for colorectal, pancreas and kidney cancers in both sexes, for melanomas and bladder cancer in men, and for breast and ovarian cancer in women. Trends in average years of life lost were stable. Almost half (48-50%) of the years of life lost due to childhood cancers were due to leukemia. Cancer is an increasing health burden in Colombia. The high average years of life lost illustrate the poor prognosis of the disease compared to other countries. Primary prevention, early detection, and adequate and timely treatments are needed to change this situation.

  16. Quench of a symmetry-broken ground state

    Giampaolo, S. M.; Zonzo, G.

    2017-01-01

    We analyze the problem of how different ground states associated with the same set of Hamiltonian parameters evolve after a sudden quench. To realize our analysis we define a quantitative approach to the local distinguishability between different ground states of a magnetically ordered phase in terms of the trace distance between the reduced density matrices obtained by projecting two ground states in the same subset. Before the quench, regardless of the particular choice of subset, any system in a magnetically ordered phase is characterized by ground states that are locally distinguishable. On the other hand, after the quench, the maximum distinguishability shows an exponential decay in time. Hence, in the limit of very long times, all the information about the particular initial ground state is lost even if the systems are integrable. We prove our claims in the framework of the magnetically ordered phases that characterize both the X Y and the N -cluster Ising models. The fact that we find similar behavior in models within different classes of symmetry makes us confident about the generality of our results.

  17. Infrasonic induced ground motions

    Science.gov (United States)

    Lin, Ting-Li

    On January 28, 2004, the CERI seismic network recorded seismic signals generated by an unknown source. Our conclusion is that the acoustic waves were initiated by an explosive source near the ground surface. The meteorological temperature and effective sound speed profiles suggested existence of an efficient near-surface waveguide that allowed the acoustic disturbance to propagate to large distances. An explosion occurring in an area of forest and farms would have limited the number of eyewitnesses. Resolution of the source might be possible by experiment or by detailed analysis of the ground motion data. A seismo-acoustic array was built to investigate thunder-induced ground motions. Two thunder events with similar N-wave waveforms but different horizontal slownesses are chosen to evaluate the credibility of using thunder as a seismic source. These impulsive acoustic waves excited P and S reverberations in the near surface that depend on both the incident wave horizontal slowness and the velocity structure in the upper 30 meters. Nineteen thunder events were chosen to further investigate the seismo-acoustic coupling. The consistent incident slowness differences between acoustic pressure and ground motions suggest that ground reverberations were first initiated somewhat away from the array. Acoustic and seismic signals were used to generate the time-domain transfer function through the deconvolution technique. Possible non-linear interaction for acoustic propagation into the soil at the surface was observed. The reverse radial initial motions suggest a low Poisson's ratio for the near-surface layer. The acoustic-to-seismic transfer functions show a consistent reverberation series of the Rayleigh wave type, which has a systematic dispersion relation to incident slownesses inferred from the seismic ground velocity. Air-coupled Rayleigh wave dispersion was used to quantitatively constrain the near-surface site structure with constraints afforded by near-surface body

  18. I've lost the person I used to be—Experiences of the consequences of fatigue following myocardial infarction

    Directory of Open Access Journals (Sweden)

    Ulla Fredriksson-Larsson

    2013-06-01

    Full Text Available Fatigue has been found to be the most frequent and bothersome symptom after myocardial infarction (MI, influencing health-related quality of life negatively. Moreover, fatigue after MI has been described as incomprehensible due to its unpredictable occurrence and lack of relationship to physical effort. The aim of this study is therefore to explore persons’ experiences of consequences of fatigue and their strategies for dealing with it 2 months after MI. In total, 18 informants, aged 42–75 years, participated in the study. Interviews were conducted and analysed using constructivist grounded theory methodology. Grounded in the data, the main consequence of fatigue, as illustrated in the core category, was: I've lost the person I used to be. It indicates a sense of reduced ability to manage daily life due to experiences of fatigue. The core category was developed from the four categories: involuntary thoughts, certainties replaced with question marks, driving with the handbrake on and just being is enough. Furthermore, attempts to relieve fatigue were limited. These findings indicate that patients with symptoms of fatigue should be supported in developing relief strategies, for example, rest and sleep hygiene as well as physical activity. In conclusion, the results show that fatigue can be understood in light of the concepts “comprehensibility” and “manageability.” They also indicate that, working from a person-centered perspective, health-care professionals can support patients experiencing post-MI fatigue by giving them opportunities to straighten out the question marks and by inviting them to discuss involuntary thoughts and feelings of being restricted in their daily life functioning.

  19. Decentralized Ground Staff Scheduling

    DEFF Research Database (Denmark)

    Sørensen, M. D.; Clausen, Jens

    2002-01-01

    Typically, ground staff scheduling is centrally planned for each terminal in an airport. The advantage of this is that the staff is efficiently utilized, but a disadvantage is that staff spends considerable time walking between stands. In this paper a decentralized approach for ground staff...... scheduling is investigated. The airport terminal is divided into zones, where each zone consists of a set of stands geographically next to each other. Staff is assigned to work in only one zone and the staff scheduling is planned decentralized for each zone. The advantage of this approach is that the staff...... work in a smaller area of the terminal and thus spends less time walking between stands. When planning decentralized the allocation of stands to flights influences the staff scheduling since the workload in a zone depends on which flights are allocated to stands in the zone. Hence solving the problem...

    We present an overview of results obtained from IBIS ground calibrations. The spectral and spatial characteristics of the detector planes and surrounding passive materials have been determined through a series of calibration campaigns. Measurements of pixel gain, energy resolution, detection uniformity, efficiency and imaging capability are presented. The key results obtained from the ground calibration have been: - optimization of the instrument tunable parameters, - determination of energy linearity for all detection modes, - determination of energy resolution as a function of energy through the range 20 keV - 3 MeV, - demonstration of imaging capability in each mode, - measurement of intrinsic detector non-uniformity and understanding of the effects of passive materials surrounding the detector plane, and - discovery (and closure) of various leakage paths through the passive shielding system.

  2. Multi-group acculturation orientations in a changing context: Palestinian Christian Arab adolescents in Israel after the lost decade.

    Science.gov (United States)

    Munayer, Salim J; Horenczyk, Gabriel

    2014-10-01

    Grounded in a contextual approach to acculturation of minorities, this study examines changes in acculturation orientations among Palestinian Christian Arab adolescents in Israel following the "lost decade of Arab-Jewish coexistence." Multi-group acculturation orientations among 237 respondents were assessed vis-à-vis two majorities--Muslim Arabs and Israeli Jews--and compared to 1998 data. Separation was the strongest endorsed orientation towards both majority groups. Comparisons with the 1998 data also show a weakening of the Integration attitude towards Israeli Jews, and also distancing from Muslim Arabs. For the examination of the "Westernisation" hypothesis, multi-dimensional scaling (MDS) analyses of perceptions of Self and group values clearly showed that, after 10 years, Palestinian Christian Arabs perceive Israeli Jewish culture as less close to Western culture, and that Self and the Christian Arab group have become much closer, suggesting an increasing identification of Palestinian Christian Arab adolescents with their ethnoreligious culture. We discuss the value of a multi-group, multi-method, and multi-wave approach to the examination of the role of the political context in acculturation processes.

  3. Sodium Contents in Dairy Cow Urine and Soil Aggregate Sizes Influence the Amount of Nitrogen Lost from Soil

    Toru Hamamoto

    2015-01-01

    Full Text Available Cow urine deposition on pasture soils is a major source of N-related environmental impacts in the dairy farming systems. The urine-N can potentially be lost to the ground water as nitrate (NO3- and to the atmosphere as nitrous oxide (N2O. These N-related environmental impacts are possibly related to the sodium (Na+ concentrations in urine. We sampled a pasture soil and separated it into three aggregate size groups (0–3, 3–5, and 5–7 mm. Then, cow urine with variable Na+ concentrations (4.3–6.1 g Na+ L−1 was added to the soil cores. We treated the cores with simulated heavy rains and measured the amounts of calcium (Ca2+, Na+, potassium (K+, and inorganic-N leached from the soils. N2O emission rates were also determined throughout the experimental period. Increasing Na+ concentration in urine decreased the loss of NO3- (−20%, after repeatedly applied simulated rain treatments (30 mm × 3, whereas it increased the loss of ammonium (31% and K+ (19%. For the loss of Ca2+ and the emissions of N2O, the effect of the Na+ concentrations was unclear. Field level studies and studies focusing on the mechanisms behind the changes in nutrient losses are needed.

  4. 'Philosophy Lost': Inquiring into the effects of the corporatized university and its implications for graduate nursing education.

    Springer, Rusla Anne; Clinton, Michael Edward

    2017-04-03

    Drawing on a comprehensive, pan-national analysis of the corporatization of Canadian universities, as well as the notions of 'parrhesiastic' mentorship and practice, the authors examine the effects of the corporatized university, its implications for graduate nursing education and nursing's relative silence on the subject. With the preponderance of business interests, the increasing dependence of universities on industry funding, cults of efficiency, research intensivity, and the pursuit of profit so prevalent in today's corporatized university, we argue that philosophical presuppositions so crucial to critical teaching, research, and reflection on nursing as a discipline are troublingly losing ground. We lament the erosion and fragmentation of philosophy, politics, and ethics as foundations for graduate education, which are increasingly perceived as less valuable, problematic, and in some cases, even burdensome. The effect of corporatization is the suppression of the critical engagement required of faculty in the everyday workings of institutions. We argue that, when the ideals of intellectual freedom, academic responsibility, duty, and obligation, as supported by philosophical thought, are smothered by the normalizing power of corporatized research agendas, philosophical approaches to inquiry and knowledge development become marginalized as scholars find themselves floundering in the face of a seeming 'philosophy lost'. © 2017 John Wiley & Sons Ltd.

  5. Outdoor ground impedance models.

    Attenborough, Keith; Bashir, Imran; Taherzadeh, Shahram

    2011-05-01

    Many models for the acoustical properties of rigid-porous media require knowledge of parameter values that are not available for outdoor ground surfaces. The relationship used between tortuosity and porosity for stacked spheres results in five characteristic impedance models that require not more than two adjustable parameters. These models and hard-backed-layer versions are considered further through numerical fitting of 42 short range level difference spectra measured over various ground surfaces. For all but eight sites, slit-pore, phenomenological and variable porosity models yield lower fitting errors than those given by the widely used one-parameter semi-empirical model. Data for 12 of 26 grassland sites and for three beech wood sites are fitted better by hard-backed-layer models. Parameter values obtained by fitting slit-pore and phenomenological models to data for relatively low flow resistivity grounds, such as forest floors, porous asphalt, and gravel, are consistent with values that have been obtained non-acoustically. Three impedance models yield reasonable fits to a narrow band excess attenuation spectrum measured at short range over railway ballast but, if extended reaction is taken into account, the hard-backed-layer version of the slit-pore model gives the most reasonable parameter values.

    2011-01-01

    Full Text Available This paper deals with the problem of optimal control for the transmission dynamics of tuberculosis (TB. A TB model that considers the existence of a new class (mainly in the African context is considered: the lost to follow up individuals. Based on the model formulated and studied in the work of Plaire Tchinda Mouofo, (2009, the TB control is formulated and solved as an optimal control theory problem using the Pontryagin's maximum principle (Pontryagin et al., 1992. This control strategy indicates how the control of the lost to follow up class can considerably influence the basic reproduction ratio so as to reduce the number of lost to follow up. Numerical results show the performance of the optimization strategy.

    Lost Circulation is a widespread problem encountered when drilling geothermal wells, and often represents a substantial portion of the cost of drilling a well. The U.S. Department of Energy sponsors research and development work at Sandia National Laboratories in an effort to reduce these lost circulation expenditures. Sandia has developed a down hole tool that improves the effectiveness and reduces th cost of lost circulation cement treatment while drilling geothermal wells. This tool, the Drillable Straddle Packer, is a low-cost disposable device that is used to isolate the loss zone and emplace the cement treatment directly into the region of concern. This report documents the design and development of the Drillabe Straddle Packer, the laboratory and field test results, and the design package that is available to transfer this technology to industry users.

    Background: Weight loss reduces body fat and lean mass, but whether these changes are influenced by macronutrient composition of the diet is unclear. Objective: We determined whether energy-reduced diets that emphasize fat, protein, or carbohydrate differentially reduce total, visceral, or hepatic fat or preserve lean mass. Design: In a subset of participants in a randomized trial of 4 weight-loss diets, body fat and lean mass (n = 424; by using dual-energy X-ray absorptiometry) and abdominal and hepatic fat (n = 165; by using computed tomography) were measured after 6 mo and 2 y. Changes from baseline were compared between assigned amounts of protein (25% compared with 15%) and fat (40% compared with 20%) and across 4 carbohydrate amounts (35% through 65%). Results: At 6 mo, participants lost a mean (±SEM) of 4.2 ± 0.3 kg (12.4%) fat and 2.1 ± 0.3 kg (3.5%) lean mass (both P fat (P ≥ 0.34), or 65% and 35% carbohydrate (P ≥ 0.27). Participants lost 2.3 ± 0.2 kg (13.8%) abdominal fat: 1.5 ± 0.2 kg (13.6%) subcutaneous fat and 0.9 ± 0.1 kg (16.1%) visceral fat (all P fat than did men relative to total-body fat loss. Participants regained ∼40% of these losses by 2 y, with no differences between diets (P ≥ 0.23). Weight loss reduced hepatic fat, but there were no differences between groups (P ≥ 0.28). Dietary goals were not fully met; self-reported contrasts were closer to 2% protein, 8% fat, and 14% carbohydrate at 6 mo and 1%, 7%, and 10%, respectively, at 2 y. Conclusion: Participants lost more fat than lean mass after consumption of all diets, with no differences in changes in body composition, abdominal fat, or hepatic fat between assigned macronutrient amounts. This trial was registered at clinicaltrials.gov as NCT00072995. PMID:22258266

    2017-05-01

    Localization-based technologies promise to keep older adults with dementia safe and support them and their caregivers during getting lost events. This paper summarizes mainly technological contributions to support the target group in these events. Moreover, important aspects of the getting lost phenomenon such as its concept and ethical issues are also briefly addressed. Papers were selected from scientific databases and gray literature. Since the topic is still in its infancy, other terms were used to find contributions associated with getting lost e.g. wandering. Trends of applying localization systems were identified as personal locators, perimeter systems and assistance systems. The first system barely considered the older adult's opinion, while assistance systems may involve context awareness to improve the support for both the elderly and the caregiver. Since few studies report multidisciplinary work with a special focus on getting lost, there is not a strong evidence of the real efficiency of localization systems or guidelines to design systems for the target group. Further research about getting lost is required to obtain insights for developing customizable systems. Moreover, considering conditions of the older adult might increase the impact of developments that combine localization technologies and artificial intelligence techniques. Implications for Rehabilitation Whilst there is no cure for dementia such as Alzheimer's, it is feasible to take advantage of technological developments to somewhat diminish its negative impact. For instance, location-based systems may provide information to early diagnose the Alzheimer's disease by assessing navigational impairments of older adults. Assessing the latest supportive technologies and methodologies may provide insights to adopt strategies to properly manage getting lost events. More user-centered designs will provide appropriate assistance to older adults. Namely, customizable systems could assist older adults

    2012-01-01

    Background Adherence to tuberculosis (TB) treatment is troublesome, due to long therapy duration, quick therapeutic response which allows the patient to disregard about the rest of their treatment and the lack of motivation on behalf of the patient for improved. The objective of this study was to develop and validate a scoring system to predict the probability of lost to follow-up outcome in TB patients as a way to identify patients suitable for directly observed treatments (DOT) and other interventions to improve adherence. Methods Two prospective cohorts, were used to develop and validate a logistic regression model. A scoring system was constructed, based on the coefficients of factors associated with a lost to follow-up outcome. The probability of lost to follow-up outcome associated with each score was calculated. Predictions in both cohorts were tested using receiver operating characteristic curves (ROC). Results The best model to predict lost to follow-up outcome included the following characteristics: immigration (1 point value), living alone (1 point) or in an institution (2 points), previous anti-TB treatment (2 points), poor patient understanding (2 points), intravenous drugs use (IDU) (4 points) or unknown IDU status (1 point). Scores of 0, 1, 2, 3, 4 and 5 points were associated with a lost to follow-up probability of 2,2% 5,4% 9,9%, 16,4%, 15%, and 28%, respectively. The ROC curve for the validation group demonstrated a good fit (AUC: 0,67 [95% CI; 0,65-0,70]). Conclusion This model has a good capacity to predict a lost to follow-up outcome. Its use could help TB Programs to determine which patients are good candidates for DOT and other strategies to improve TB treatment adherence. PMID:22938040

    A Faraday-cup type lost-fast ion probe (FLIP) has been designed and installed in Heliotron J for the purpose of the studies of interaction between fast ions and MHD instabilities. The FLIP can measure the co-going fast ions whose energy is in the range of 1.7-42.5 keV (proton) and pitch angle of 90∘-140∘, especially for fast ions having the injection energy of neutral beam injection (NBI). The FLIP successfully measured the re-entering passing ions and trapped lost-fast ions caused by fast-ion-driven energetic particle modes in NBI heated plasmas.

    This report summarizes the results and the assumptions used in an analysis of the potential “lost efficiency opportunities” in the buildings sector. These targets of opportunity are those end-uses, applications, practices, and portions of the buildings market which are not currently being addressed, or addressed fully, by the Building Technologies Program (BTP) due to lack of resources. The lost opportunities, while a significant increase in effort and impact in the buildings sector, still represent only a small portion of the full technical potential for energy efficiency in buildings.

  3. Man versus Rivers: the lost equilibrium of the Tisza River due to engineering works

    2016-04-01

    The direct and indirect human impacts alter the catchment and the channel characteristics, which will result in further hydro-morphological alterations of rivers. The modified fluvial environment will create new hydrological hazards for the society, so for the successful and sustainable hazard and risk management it is important to evaluate the equilibrium and sensitivity of rivers. The aim of the paper is to evaluate the hydrological and morphological effects of engineering works along the Tisza River, Hungary. Based on the trends of the different fluvial processes the equilibrium of the river will be evaluated to ground further engineering works. The Tisza River, was one of the first systematically regulated rivers in Europe. In the late 19th century artificial cut-offs were made, shortening the river by ca. 30%. The hydrology and the morphology of the Tisza adapted to this, as the channel became temporarily wider and deeper (by 20-25%). The cut-offs had an effect on the channel for ca. 60-70 years. Simultaneously, artificial levees were built, thus the overbank floodplain aggradation became more intensive (from 0.02-0.07 cm/y to 0.3-0.8 mm/y). The floodplain aggradation became higher by 2-4 times since 1970's, as the vegetation became denser. However, in the 21st c. the floodplain vegetation became so uncontrollably dense, that the pattern and rate of accumulation changed again, and now it is limited just to the banks. So the levee could be considered as continuous disturbing factor, besides, the unmanaged floodplain vegetation appeared as a new disturbing force accelerating the processes. In the 20th century revetments were constructed to stop the lateral migration of the channel. This resulted in channel distortion, as it became sharper and the cross-sectional area decreased by 28%. As revetments were constructed along ca. 51% of the channel, the meandering channel forms became replaced features characteristic in incising rivers, for example point

  4. The orphaning experience: descriptions from Ugandan youth who have lost parents to HIV/AIDS

    Full Text Available Abstract The HIV/AIDS epidemic has continued to pose significant challenges to countries in Sub-Saharan Africa. Millions of African children and youth have lost parents to HIV/AIDS leaving a generation of orphans to be cared for within extended family systems and communities. The experiences of youth who have lost parents to the HIV/AIDS epidemic provide an important ingress into this complex, evolving, multi-dimensional phenomenon. A fundamental qualitative descriptive study was conducted to develop a culturally relevant and comprehensive description of the experiences of orphanhood from the perspectives of Ugandan youth. A purposeful sample of 13 youth who had lost one or both parents to HIV/AIDS and who were affiliated with a non-governmental organization providing support to orphans were interviewed. Youth orphaned by HIV/AIDS described the experience of orphanhood beginning with parental illness, not death. Several losses were associated with the death of a parent including lost social capitol, educational opportunities and monetary assets. Unique findings revealed that youth experienced culturally specific stigma and conflict which was distinctly related to their HIV/AIDS orphan status. Exploitation within extended cultural family systems was also reported. Results from this study suggest that there is a pressing need to identify and provide culturally appropriate services for these Ugandan youth prior to and after the loss of a parent(s.

    The complex management of acromegaly has transformed this disease into a chronic condition, with the risk of patients being lost to follow-up. The objective of this study was to estimate the proportion of acromegalic patients lost to follow-up in France and to determine the impact that abandoning follow-up has on the disease and its management. ACROSPECT was a French national, multicentre, cross-sectional, observational study. Acromegalic patients were considered lost to follow-up if no new information had been entered in their hospital records during the previous 2 years. They were traced where possible, and data were collected by means of a recall visit or questionnaire. In the study population, 21% of the 2392 acromegalic patients initially followed in 25 tertiary endocrinology centres were lost to follow-up. At their last follow-up visit, 30% were uncontrolled, 33% were receiving medical therapy and 53% had residual tumour. Of the 362 traced, 62 had died and 77% were receiving follow-up elsewhere; the leading reason for abandoning follow-up was that they had not been informed that it was necessary. Our analysis of the questionnaires suggests that they were not receiving optimal follow-up. This study underlines the need to better inform acromegalic patients of the need for long-term follow-up, the absence of which could be detrimental to patients' health, and to develop shared care for what must now be regarded as a chronic disease.

  17. Effect of Process Parameters on Porosity in Aluminum Lost Foam Process

    Institute of Scientific and Technical Information of China (English)

    Kiyoung KIM; Kyongwhoan LEE

    2005-01-01

    Porosity is a main defect in aluminum alloy castings, which is also thought to be severe in aluminum alloy castings produced by lost foam process due to the pyrolysis of the polystyrene foam pattern during pouring. Fundamental experiments were carried out to evaluate the effect of process parameters such as the melt treatment, the cooling rate and the density of expanded polystyrene (EPS) foam on porosity in A356.2 bar casting. The effect of melt treatment including degassing and refining was investigated. The effect of cooling rate was also evaluated by changing the mold packing material such as the silica sand, the zircon sand and the steel shots. Gas entrapment due to the turbulent metal flow during mold filling in conventional molding process results in porosity. Mold filling sequence in lost foam process is different from that in conventional molding process. The effect of molten metal flow was estimated by comparing the density of the casting by conventional sodium silicate molding with that by lost foam process. Density measurement was conducted to analyze the extent of porosity in the casting. Source of the porosity in lost foam process can be divided into two factors, i.e. turbulence in molten metal flow and entraining residue or gas from the pattern during pouring.

  19. Workers' compensation loss prevention representative contact and risk of lost-time injury in construction policyholders.

    Schofield, Katherine E; Alexander, Bruce H; Gerberich, Susan G; MacLehose, Richard F

    2017-09-01

    Insurance loss prevention (LP) representatives have access and contact with businesses and employees to provide targeted safety and health resources. Construction firms, especially those smaller in size, are a high-risk population. This research evaluated the association between LP rep contact and risk for lost-time injuries in construction policyholders. Workers' compensation data were utilized to track LP rep contact with policyholders and incidence of lost-time injury over time. Survival analysis with repeated events modeling calculated hazard ratios (HR) and 95% confidence intervals (CI). Compared no LP contact, one contact was associated with a 27% reduction of risk (HR=0.73, CI=0.65-0.82), two with a 41% (HR=0.59, CI=0.51-0.68), and three or more contacts with a 28% reduction of risk (HR=0.72, CI=0.65-0.81). LP reps appear to be a valuable partner in efforts to reduce injury burden. Their presence or contact with policyholders is consistent with reduction in overall incidence of lost-time injuries. Reduction in lost-time injuries, resulting in reduced workers' compensation costs for policyholders and insurance companies, builds a business-case for safety and injury prevention. LP reps are often a low or no-cost benefit for insurance policyholders and may be an important injury prevention resource for small firms and/or those with lack of safety resources and staff.

    Full Text Available Background: The aesthetic has an important role in social life, especially the anterior teeth. The aesthetic abnormality of anterior teeth i.e. discoloration, malpotition or the anterior teeth with crown damage for more than one third or all part of crown is lost due to caries or other causes, will influence its appearance especially during smile. Purpose: The aim of this case report, therefore, is to show how teeth with clinical crown lost or only the root left still can be treated by endorestoration treatment in order to reconstruct the shape and function of the teeth similar to the original ones. Case: Female 52 years old with the lost crown of anterior teeth. The patient did not want her teeth to be extracted. Case Management: The abnormality of these teeth are still able to be reconstructed by endorestoration i.e. endodontic treatment with post and core insertion in the root canal will increase its retention and recovery by the porcelain crown fused to metal to recover the original formation and aesthetic and thus has the normal refunction. The treatment, it improve the confidence of the patient, and also can function normally. The patient did not feel pain. Ronsenography showed the periapical lesion diminished, the neighbor gingival was going better in both function and color. Conclusion: Endorestoration treatment on the anterior teeth with lost crown could recover the normal function, dental aesthetic and self confidence.

    2016-10-01

    In fusion plasmas, fast ions are produced by neutral beam injections (NBI), ion cyclotron heating (ICH) and fusion reactions. Some of fast ions are lost from fusion plasmas because of some kinds of drift and instability. These lost fast ions may cause damages on plasma facing components such as divertors and diagnostic instruments in fusion reactors. Therefore, wall heat loads by lost fast ions in the Large Helical Device (LHD) is under investigation. For this purpose, we have been developing the Monte-Carlo code for the quantitative evaluation of wall heat loads based on following the guiding center orbits of fast ions. Using this code, we investigate wall heat loads and hitting points of lost fast ions produced by NBI in LHD. Magnetic field configurations, which depend on beta values, affect orbits of fast ions and wall heat loads. Therefore, the wall heat loads by fast ions in equilibrium magnetic fields including finite beta effect and magnetic islands are quantitatively evaluated. The differences of wall heat loads and particle deposition patterns for cases of the vacuum field and various beta equilibrium fields will be presented at the meeting.

    LOFT, the Large Observatory For X-ray Timing, was one of the ESA M3 mission candidates that completed their assessment phase at the end of 2013. LOFT is equipped with two instruments, the Large Area Detector (LAD) and the Wide Field Monitor (WFM). The LAD performs pointed observations of several targets per orbit (~90 minutes), providing roughly ~80 GB of proprietary data per day (the proprietary period will be 12 months). The WFM continuously monitors about 1/3 of the sky at a time and provides data for about ~100 sources a day, resulting in a total of ~20 GB of additional telemetry. The LOFT Burst alert System additionally identifies on-board bright impulsive events (e.g., Gamma-ray Bursts, GRBs) and broadcasts the corresponding position and trigger time to the ground using a dedicated system of ~15 VHF receivers. All WFM data are planned to be made public immediately. In this contribution we summarize the planned organization of the LOFT ground segment (GS), as established in the mission Yellow Book 1 .

  16. Years of life lost due to external causes of death in the lodz province, poland.

    Directory of Open Access Journals (Sweden)

    Malgorzata Pikala

    Full Text Available BACKGROUND: The aim of the study is the analysis of years of life lost due to external causes of death, particularly due to traffic accidents and suicides. MATERIALS AND METHODS: The study material includes a database containing information gathered from 376,281 death certificates of inhabitants of the Lodz province who died between 1999 and 2010. The Lodz province is characterized by the highest mortality rates in Poland. The SEYLLp (Standard Expected Years of Life Lost per living person and the SEYLLd (per death indices were used to determine years of life lost. Joinpoint models were used to analyze time trends. RESULTS: In 2010, deaths due to external causes constituted 6.0% of the total number of deaths. The standardized death rate (SDR due to external causes was 110.0 per 100,000 males and was five times higher than for females (22.0 per 100,000 females. In 2010, the SEYLLp due to external causes was 3746 per 100,000 males and 721 per 100,000 females. Among males, suicides and traffic accidents were the most common causes of death (the values of the SEYLLp were: 1098 years and 887 years per 100,000 people, respectively. Among females, the SEYLLp values were 183 years due to traffic accidents and 143 years due to suicides (per 100,000 people. CONCLUSIONS: A decrease in the number of years of life lost due to external causes is much higher among females. The authors observe that a growing number of suicides contribute to an increase in the value of the SEYLLp index. This directly contributes to over-mortality of males due to external causes. The analysis of the years of life lost focuses on the social and economic aspects of premature mortality due to external causes.

    2002-12-01

    A field study using 621 "lost" letters was conducted in the city of Mobile and in small towns in mostly rural Baldwin County, Alabama. Milgram's lost letter technique was validated against the actual votes cast during the November 7, 2000 General Election. The technique was successful as an unobtrusive measure useful for predicting patterns of voting behavior. Rates of return of lost letters "in favor of and opposed to legalizing interracial marriage" agreed with the actual election returns (chi-square "goodness of fit"). Community size seemed associated with return of lost letters.

The concept of design is defined as being imaginative and mindful to a number of actors...... in a network of humans and non-humans, highlighting that design objects and the designer as an authority are constructed throughout this endeavour. The illustrative case example is drawn from product development in a rubber valve factory in Jutland in Denmark. The key contribution to a general core of design...... research is an articulation of design activity taking place as a middle ground and as an intermixture between a ‘scientific’ regime of knowledge transfer and a capital ‘D’ ‘Designerly’ regime of authoring....

  20. Wind-induced ground motion

    Naderyan, Vahid; Hickey, Craig J.; Raspet, Richard

    2016-02-01

    Wind noise is a problem in seismic surveys and can mask the seismic signals at low frequency. This research investigates ground motions caused by wind pressure and shear stress perturbations on the ground surface. A prediction of the ground displacement spectra using the measured ground properties and predicted pressure and shear stress at the ground surface is developed. Field measurements are conducted at a site having a flat terrain and low ambient seismic noise. Triaxial geophones are deployed at different depths to study the wind-induced ground vibrations as a function of depth and wind velocity. Comparison of the predicted to the measured wind-induced ground displacement spectra shows good agreement for the vertical component but significant underprediction for the horizontal components. To validate the theoretical model, a test experiment is designed to exert controlled normal pressure and shear stress on the ground using a vertical and a horizontal mass-spring apparatus. This experiment verifies the linear elastic rheology and the quasi-static displacements assumptions of the model. The results indicate that the existing surface shear stress models significantly underestimate the wind shear stress at the ground surface and the amplitude of the fluctuation shear stress must be of the same order of magnitude as the normal pressure. Measurement results show that mounting the geophones flush with the ground provides a significant reduction in wind noise on all three components of the geophone. Further reduction in wind noise with depth of burial is small for depths up to 40 cm.

    1998-10-01

    The legendary 'Ciudad Blanca' of Honduras was first referred to under the name Xucutaco by the Spanish conquistador Hernan Cortes already in 1526. Located in the remote, impenetrable and incompletely mapped rainforest of the Mosquito Coast, it was never conquered by the Spanish. With the time, it was slowly abandoned and forgotten. Two JERS-1 and one ERS-2 SLC Synthetic Aperture Radar (SAR) images have been used to identify and to locate the lost city, a task made difficult due to the thick vegetation cover. To this end, advanced processing tools for the detection of artificial targets under forest cover, and for SAR data fusion have been used. Among the techniques used, a new Bayesian Distribution Entropy Maximum A Posteriori (DE-MAP) vector speckle filter, particularly suited for the restoration of a strongly textured scene, has been used to enhance the SAR images. This new speckle filter incorporates a statistical description of the effects of the SAR imaging system: in order to account for the effects due to the spatial correlation of the speckle in SAR images, an estimator originating from the local spatial autocorrelation function (ACF) of the SAR signal are incorporated to this filter, to refine the evaluation of the non-stationary first order local statistics, to improve the restoration of the scene textural properties, and to preserve the useful spatial resolution in the speckle filtered image. On the other hand, radargrammetric techniques have been used to: (1) produce a Digital Elevation Model (DEM) of the study area; (2) fuse ERS and JERS information in order to allow visual identification of the remnants of Ciudad Blanca by visual photo-interpretation. Using the processed images, geocoded UTM spatio-maps of the region have also been produced to locate accurately our findings, and guide a ground expedition in the future.

    1983-01-01

    This study examines the psychological and psychopathological reactions that may appear in a man when his partner aborts. The small amount of literature that exists on the subjects was examined, and several men were, interviewed at the time their partners aborted voluntarely. It turns out that in spite of the man's lack of recognition of any reactions (reinforced by current attitudes and by the scant psychological and medical interest in the subject), there is considerable emotional involvement in the lost parenthood, both for the man and the woman. As revealed by the interviews, this involvement may manifest itself in persecutory or depressive anxiety and psychosomatic symptoms. Moreover, but very rarely, real and typical psychopathological symptoms may appear, such as depression and behavioural disorders. The appearance of these reactions is linked to the problems and conflicts aroused by prospective fatherhood, leading to a comparison between the experiences of fuliwed fatherhood and those of fatherhood lost.

    2004-01-01

    The adaptive reconstruction for the lost information of the rectangular image area is very important for the robust transmission and restoration of the image. In this paper, a new reconstruction method based on the Discrete Cosine Transform (DCT) domain has been put forward. According to the low pass character of the human visual system and the energy distribution of the DCT coefficients on the rectangular boundary, the DCT coefficients of the rectangular image area are adaptively selected and recovered. After the Inverse Discrete Cosine Transform (IDCT), the lost information of the rectangular image area can be reconstructed. The experiments have demonstrated that the subjective and objective qualities of the reconstructed images are enhanced greatly than before.

    We have examined the observed currents in the front foils of the JET Faraday cup lost alpha particle diagnostic KA-2. In particular, we have sought to understand the currents during Ohmic plasmas for which the ion flux at the detectors was initially assumed to be negligible. We have considered two sources of this current: plasma ions (both deuterium and impurity) in the vicinity of the detector (including charge exchange neutrals) and photoemission from scattered UV radiation. Based upon modeling and empirical observation, the latter source appears most likely and, moreover, seems to be applicable to the currents in the front foil during ELMy H-mode plasmas. A very thin gold or nickel foil attached to the present detector aperture is proposed as a solution to this problem, and realistic calculations of expected fluxes of lost energetic neutral beam ions during TF ripple experiments are presented as justification of this proposed solution.

    2008-01-01

    In lost foam casting (LFC) the foam pattern is the key criterion, and the filling process is crucial to ensure the high quality of the foam pattern. Filling which lacks uniformity and denseness will cause various defects and affect the surface quality of the casting. The influential factors of the filling process are realized in this research. Optimization of the filling process, enhancement of efficiency, decrease of waste, etc., are obtained by the numerical simulation of the filling process using a computer. The equations governing the dense gas-solid two-phase flow are established, and the physical significance of each equation is discussed. The Euler/Lagrange numerical model is used to simulate the fluid dynamic characteristics of the dense two-phase flow during the mould filling process in lost foam casting. The experiments and numerical results showed that this method can be a very promising tool in the mould filling simulation of beads' movement.

    Full Text Available Every town hss its own architectural performance. And architecture is not merely a physical landscape of buildings in a town,, as seen by the observer, but it has a deeper mening, which displays the art of structures and constructions. It is a sequence of buildings along the course of its history (Aldo Rossi, 1980. A Town is a complete work of art, performed by men of urban knowledge. Tehe concept of a town or urban workmanship arises from time to time as a work of art in multiple variations, together and according to spirit of the time, included its aspects of belief and religion. The urban work of art or urban artefact is always related to location, historical events and the spesific urban look. Generally a town has particular rythm and dynamics, at least it does not remain static. Therefore it is quite right, when we say, that a town represents the course of its history and technology during the period of its existence. But when we scrutinise alongthe historical and visual systems, it turns out that so many physical and sociqal spaces have been altered with regard to their quality and quantity, as result mis management ot the physical and social spaces by less careful urban reformists. they may bring about certain inbalancy in the system, destroying public imagination and memory about the identity and message conceived at the time of their construction. At the this may affect a condition, commonly called the lost space. Surabaya is one of the larger towns in Indonesia, which afrtime possessed a number of urban artefacts and workmanship. One of which is the Tunjungan Street, designed and developed by the Gemeente Administration of the Duutch as comercial corriodor of the town, with all its advantages and shortcomings. In spite of the fact that it has never been touched by the hands of the prominent urban planner Mr. Thomas C.

    2016-01-01

    ABSTRACT OBJECTIVE To estimate the potential years of life lost by road traffic injuries three years after the beginning of the Decade of Action for Traffic Safety. METHODS We analyzed the data of the Sistema de Informações sobre Mortalidade (SIM – Mortality Information System) related to road traffic injuries, in 2013. We estimated the crude and standardized mortality rates for Brazil and geographic regions. We calculated, for the Country, the proportional mortality according to age groups, education level, race/skin color, and type or quality of the victim while user of the public highway. We estimated the potential years of life lost according to sex. RESULTS The mortality rate in 2013 was of 21.0 deaths per 100,000 inhabitants for the Country. The Midwest region presented the highest rate (29.9 deaths per 100,000 inhabitants). Most of the deaths by road traffic injuries took place with males (34.9 deaths per 100,000 males). More than half of the people who have died because of road traffic injuries were of black race/skin color, young adults (24.2%), individuals with low schooling (24.0%), and motorcyclists (28.5%). The mortality rate in the triennium 2011-2013 decreased 4.1%, but increased among motorcyclists. Across the Country, more than a million of potential years of life were lost, in 2013, because of road traffic injuries, especially in the age group of 20 to 29 years. CONCLUSIONS The impact of the high mortality rate is of over a million of potential years of life lost by road traffic injuries, especially among adults in productive age (early mortality), in only one year, representing extreme social cost arising from a cause of death that could be prevented. Despite the reduction of mortality by road traffic injuries from 2011 to 2013, the mortality rates increased among motorcyclists. PMID:27706375

    2016-11-01

    Full Text Available China is entering a period of rapid urban development. With the rapid expansion of cities, a large number of peasants have lost their land as a result. Given the development of urbanization, safeguarding the rights and interests of land-lost peasants in the process of urbanization has become a new topic of interest in China. In this study, based on game theory, we analyze the interests of the local government and land-lost peasants in several rounds of the citizenization process. The result demonstrated the following: (1 this paper proposed that overall interest declines in the entire game, in which the peasant can obtain a greater share of benefits from bargaining with the local government; (2 However, a long bargaining process would lead to the diminishment of peasants’ rights and benefits. In contrast, the local government would obtain greater share of benefits than the peasant and would obtain fewer benefits than at the beginning of the process. Therefore, both sides expect to end the game process early; (3 Under the “rational economic man” process, this process will always tend to be one in which one party struggles while the other compromises. Therefore, in the game, the game process will not reach a game equilibrium state and both sides will be at a stalemate; (4 The local government, as the power owner, is expected to surrender its interests as the “rational economic man” for the Pareto optimality; (5 Finally, we proposed policy recommendations for the sustainability of citizenization. Increasing the public service benefits, establishing the system of subsistence allowances and raising the minimum living allowance of citizenization, improving the training and employment service system for the peasant can improve land-lost peasants’ acceptance in the game.

    Derivation of induced pluripotent stem (iPS) cells is mainly an epigenetic reprogramming process. It is still quite controversial how genomic imprinting is reprogrammed in iPS cells. Thus, we derived multiple iPS clones from genetically identical mouse somatic cells. We found that parentally inherited imprint was variably lost among these iPS clones. Concurrent with the loss of DNA methylation imprint at the corresponding Snrpn and Peg3 imprinted regions, parental origin-specific expression o...

    We used 13 years (1995-2007) of capture-mark-recapture data to assess population dynamics of endangered Lost River suckers Deltistes luxatus and shortnose suckers Chasmistes brevirostris in Upper Klamath Lake, Oregon. The Cormack-Jolly-Seber method was used to estimate survival, and information theoretic modeling was used to assess variation due to time, gender, species, and spawning subpopulations. Length data were used to detect multiple year-class failures and events of high recruitment into adult spawning populations. Average annual survival probability was 0.88 for Lost River suckers and 0.76 for shortnose suckers. Mean life span estimates based on these survival rates indicated that Lost River suckers survived long enough on average to attempt reproduction eight times, whereas shortnose suckers only survived to spawn three to four times. Shortnose sucker survival was not only poor in years of fish kills (1995-1997) but also was low in years without fish kills (i.e., 2002 and 2004). This suggests that high mortality occurs in some years but is not necessarily associated with fish kills. Annual survival probabilities were not only different between the two species but also differed between two spawning subpopulations of Lost River suckers. Length composition data indicated that recruitment into spawning populations only occurred intermittently. Populations of both species transitioned from primarily old individuals with little size diversity and consistently poor recruitment in the late 1980s and early 1990s to mostly small, recruit-sized fish by the late 1990s. A better understanding of the factors influencing adult survival and recruitment into spawning populations is needed. Monitoring these vital parameters will provide a quantitative means to evaluate population status and assess the effectiveness of conservation and recovery efforts.

    Deaths by external causes represent one of the most important challenges for public health and are the second cause of death in Brazil. The aim of this study was to analyze differentials in mortality by external causes according to race/skin color. A descriptive study was carried out in Salvador, Northeastern Brazil, using 9,626 cases of deaths by external causes between 1998 and 2003. Data were obtained from the Forensic Medicine Institute and from Instituto Brasileiro de Geografia e Estatística (Brazilian Institute of Geography and Statistics). The indicator 'potential years of life lost' was utilized to identify the existence of differences among age groups, sex groups and race/skin color groups. Deaths by external causes provoked the loss of 339,220 potential years of life, of which 210,000 were due to homicides. Nonwhite individuals died at earlier ages and lost 12.2 times as much potential years of life due to deaths by homicidies than white individuals. Although the nonwhite (black and mixed) population was three times larger than the white population, its number of potential years of life lost was 30 times higher. The population of blacks was 11.4 % smaller than the white population, but its loss of potential years of life was almost three times higher. Even after the adjustment for age, the differences observed in the indicator potential years of life lost/100,000 inhabitants and in the ratios between strata according to race/skin color were maintained. The results showed differentials in mortality by external causes according to race/skin color in Salvador. The nonwhite population had greater loss of potential years of life, higher average number of years not lived and, on average, they died at an earlier age due to homicides, traffic accidents an all other external causes.

    The health indicator disability-adjusted life years combines the fatal and nonfatal consequences of a disease in a single measure. The aim of this study was to evaluate the burden of ischemic heart disease in 2008 in Spain by calculating disability-adjusted life years. The years of life lost due to premature death were calculated using the ischemic heart disease deaths by age and sex recorded in the Spanish National Institute of Statistics and the life-table in the 2010 Global Burden of Disease study. The years lived with disability, calculated for acute coronary syndrome, stable angina, and ischemic heart failure, used hospital discharge data and information from population studies. Disability weights were taken from the 2010 Global Burden of Disease study. We calculated crude and age standardized rates (European Standard Population). Univariate sensitivity analyses were performed. In 2008, 539 570 disability-adjusted life years were lost due to ischemic heart disease in Spain (crude rate, 11.8/1000 population; standardized, 8.6/1000). Of the total years lost, 96% were due to premature death and 4% due to disability. Among the years lost due to disability, heart failure accounted for 83%, stable angina 15%, and acute coronary syndrome 2%. In the sensitivity analysis, weighting by age was the factor that changed the results to the greatest degree. Ischemic heart disease continues to have a huge impact on the health of our population, mainly because of premature death. The results of this study provide an overall vision of the epidemiologic situation in Spain and could serve as the basis for evaluating interventions targeting the acute and chronic manifestations of cardiac ischemia.

    Full Text Available Attitudes toward traditional and chiropractic medicine were compared using Milgram's lost letter technique. A total of 192 letters were placed on the windshields of vehicles in parking lots at six restaurants and department stores in each of four quadrants of a medium-sized, Southeastern city. These letters were addressed to "Admissions" at either a fictitious Institute of Medicine or Institute of Chiropractic Care. Return addresses included either a male or a female name. Thus, those who found a lost letter were faced with the option of returning or not returning a letter from either a male or a female, addressed to an Institute of traditional or non-traditional medicine. After examining previous studies which had used the lost letter technique, numerous methodological improvements were implemented. For example, letters were randomly assigned to potential drop spots for each of 24 study locations (six study locations in each of four city quadrants, and a Latin square design was used to control for possible order effects in the four study conditions that were implemented. Nearly 65% of the letters (124 of 192 were returned. We found: 1 letters addressed to a fictitious Institute of Chiropractic Care were just as likely to be returned as those addressed to a fictitious Institute of Medicine; 2 letters with female return addresses were as likely to be returned as those with male return addresses; 3 there was no interaction between study conditions; 4 based on what was essentially a replication study, a comparison of the pattern of returns using the first and second cycle of lost letters (n = 96 for each cycle revealed an equivalent pattern of no-difference findings. DOI: 10.2458/azu_jmmss.v1i1.78

    Different reasons for lost to follow-up are assumed. Besides "objective" reasons, "subjective" reasons and satisfaction contribute to treatment adherence. Retrospective studies usually lack the possibility of acquisition of additional outcome information. Purpose of this study was to determine outcome and factors for patients not returning for follow-up. Between 2002 and 2009, 380 patients underwent internal fixation for tibial plateau fractures. Short Musculoskeletal Function Assessment (SMFA) was collected at 6, 12, and 24 months as long as patients returned for follow-up. Pain and range of motion were measured. Records were studied for reasons of termination of follow-up. Statistical analysis was performed comparing lost to follow-up versus continued office visits regarding demographics, contributing factors, and SMFA. Two hundred fifty-nine patients were followed until treatment was completed (PRN), while 120 patients (32 %) terminated further follow-up. Patients in the 12- and 24-month follow-up groups were older (p = 0.02; p leaving treatment untimely and those being released from office visits. Follow-up remains important to obtain as much up-to-date information as possible. The current study does not support the assumption that patients lost to follow-up have a different SMFA outcome than patients returning until PRN. III.

  18. Estimation of Wellbore and Formation Temperatures during the Drilling Process under Lost Circulation Conditions

    2013-01-01

    Full Text Available Significant change of wellbore and surrounding formation temperatures during the whole drilling process for oil and gas resources often leads by annulus fluid fluxes into formation and may pose a threat to operational security of drilling and completion process. Based on energy exchange mechanisms of wellbore and formation systems during circulation and shut-in stages under lost circulation conditions, a set of partial differential equations were developed to account for the transient heat exchange process between wellbore and formation. A finite difference method was used to solve the transient heat transfer models, which enables the wellbore and formation temperature profiles to be accurately predicted. Moreover, heat exchange generated by heat convection due to circulation losses to the rock surrounding a well was also considered in the mathematical model. The results indicated that the lost circulation zone and the casing programme had significant effects on the temperature distributions of wellbore and formation. The disturbance distance of formation temperature was influenced by circulation and shut-in stages. A comparative perfection theoretical basis for temperature distribution of wellbore-formation system in a deep well drilling was developed in presence of lost circulation.

    Full Text Available This paper compares the types of two commercial spaces in modern Japan, shopping mall and “traditional” shopping district called Shotengai, from the viewpoint of commercial space as the third space in the city. Particularly in the discourse of commercial spaces in Japan, "shopping district" has been portrayed tied to nostalgia. Therefore, the transition of commercial space is always accompanied by a discourse of the" Lost." However, there is no unified opinion about what's been lost in the process of this transition in fact. In this paper, we extract the social category by considering focus on discourse for both places. As a specific object I use to target the research papers and journal articles in Japan. Because these documents are discussed by distinct main thesis and based on specific data, I adopt these materials. After extraction of social category, through the comparison of the two discourses, I reveal what kind of nature is the "Lost" at the commercial spaces as the third place in the city. I also discuss how this change is related the changes in Japanese social relationship and community.

  20. U12 type introns were lost at multiple occasions during evolution

    Bartschat Sebastian

    2010-02-01

    Full Text Available Abstract Background Two categories of introns are known, a common U2 type and a rare U12 type. These two types of introns are removed by distinct spliceosomes. The phylogenetic distribution of spliceosomal RNAs that are characteristic of the U12 spliceosome, i.e. the U11, U12, U4atac and U6atac RNAs, suggest that U12 spliceosomes were lost in many phylogenetic groups. We have now examined the distribution of U2 and U12 introns in many of these groups. Results U2 and U12 introns were predicted by making use of available EST and genomic sequences. The results show that in species or branches where U12 spliceosomal components are missing, also U12 type of introns are lacking. Examples are the choanoflagellate Monosiga brevicollis, Entamoeba histolytica, green algae, diatoms, and the fungal lineage Basidiomycota. Furthermore, whereas U12 splicing does not occur in Caenorhabditis elegans, U12 introns as well as U12 snRNAs are present in Trichinella spiralis, which is deeply branching in the nematode tree. A comparison of homologous genes in T. spiralis and C. elegans revealed different mechanisms whereby U12 introns were lost. Conclusions The phylogenetic distribution of U12 introns and spliceosomal RNAs give further support to an early origin of U12 dependent splicing. In addition, this distribution identifies a large number of instances during eukaryotic evolution where such splicing was lost.
