  1. Preconception optimization of glycaemic control in diabetes.

    Islam, Najmul

    2016-09-01

    The prevalence of Diabetes Mellitus is increasing worldwide. In developing countries 25% of adult females with diabetes are in the reproductive age. Thus in developing countries increased number of pregnancies are complicated by diabetes. Uncontrolled diabetes in pregnancy is associated with increased risk for both mother and foetus. These risks can be minimized by good control of diabetes before and during pregnancy. Management in the preconception period is discussed in this review article. Detailed management involves general advice of lifestyle modification followed by specific details of screening for complications of diabetes. Changes in the drugs for both glycaemic control and other co-morbid conditions are discussed. The recommended insulin regimen in the preconception period and monitoring of glycaemic control by self-monitoring of blood glucose (SMBG) and HbA1C has also been highlighted.

    AIMS: To investigate the association between glycaemic control and patient socio-demographics, activation level, diabetes-related distress, assessment of care, knowledge of target HbA(1c), and self-management behaviours, and to determine to what extent these factors explain the variance in HbA(1c......) in a large Danish population of patients with Type 2 diabetes. METHODS: Cross-sectional survey and record review of 2045 patients from a specialist diabetes clinic. Validated scales measured patient activation, self-management behaviours, diabetes-related emotional distress, and perceived care...... and behaviour, specific treatment modalities and glycaemic control. Knowledge of treatment goals, achieving patient activation in coping with diabetes, and lowering disease-related emotional stress are important patient education goals. However, the large unexplained component of HbA(1c) variance highlights...

    Full Text Available Introduction: The factors affecting the control of diabetes are complex and varied. However, little is documented in the literature on the overall knowledge of diabetic patients about glycaemic control. This study explored the patients’ perspectives on the challenges of glycaemic control.Methods: In this qualitative study, semi-structured interviews were conducted with seventeen purposively selected diabetic patients with HBA1c ≥ 9% at Mthatha General Hospital, South Africa. The interviews were conducted in the isiXhosa language and were audiotaped. Two experienced qualitative researchers independently transcribed and translated the interviews.Thematic content analysis was conducted.Results: Three main themes emerged: overall knowledge of diabetes and treatment targets, factors affecting the control of diabetes and how glycaemic control could be improved.The majority of the participants demonstrated poor knowledge of treatment targets for diabetes. The majority of the participants reported that lack of money affected their control of diabetes. Some of the participants reported that the nearest clinics do not have doctors; hence,they are compelled to travel long distances to see doctors.Conclusion: Poverty, lack of knowledge and access to doctors affect the control of diabetes in the rural communities of Mthatha, South Africa. The government should address recruitment and retention of doctors in primary health care.

    Full Text Available Background: Achieving good glycaemic control is important in diabetes management. However, poor glycaemic control is widely reported. This article assessed the prevalence of uncontrolled and poor glycaemic control among Libyans with type 2 diabetes and examined the relative contribution of diabetes coping behaviours to their glycaemic control status. Methods: A cross-sectional study was undertaken in 2013 in a large diabetes centre in Tripoli. The study included 523 respondents. Diabetes coping behaviours were measured using the revised version of the Summary of Diabetes Self-Care Activities measure (SDSCA and the eight-item Morisky Medication Adherence Scale (MMAS-8©, while glycaemic control status was based on the HbA1c level. Results: Mean HbA1c was 8.9 (±2.1, and of the 523 patients, only 114 (21.8% attained the glycaemic control target of HbAc1 of less than 7.0%. Females (OR=1.74, 95% CI=1.03–2.91, patients on insulin and oral hypoglycaemic agents (OR=1.92, 95% CI=1.05–3.54, patients on insulin (OR=3.14, 95% CI=1.66–6.03, and low-medication adherents (OR=2.25, 95% CI=1.36–3.73 were more likely to have uncontrolled and poor glycaemic control, while exercise contributed to glycaemic control status as a protective factor (OR=0.85, 95% CI=0.77–0.94. Conclusion: The findings from this study showed the considerable burden of uncontrolled and poor glycaemic control in one of the largest diabetes care settings in Libya. Medication adherence as well as exercise promotion programs would help in reducing the magnitude of poor glycaemic control.

    Full Text Available Diabetes mellitus is not only a major burden in the developed world, it is also an increasing health problem in less developed countries. Although health education could be a tool to achieve better glycaemic control, it is important to understand that health education should be adjusted to patients’ literacy, cultural environment and economic status. Among other factors, lack of money has an influence on the outcome of diabetes mellitus. Thus the purpose of the study is to identify factors contributing to poor glycaemia control in diabetic patients. Data was collected using self-report questionnaire on a convenient sample of 32 diabetic patients and unstructured, open-ended interviews on eight patients’ inorder to allow them freedom of expressing themselves with regard to factors that contribute to poor glycaemic control on diabetic patients. Data was then analysed using a computer program called Statistical Package for Social Sciences. The socioeconomic factors appeared to have significant influence on glycaemic control among participants, for instance 75% of the total subjects (32 indicated that they experienced problems of accessing health care services due to lack of money. Ignorance related to where to seek support system such as educational programme, and nutrition counselling were factors that were identified to contribute to diabetic patients’ poor glycaemia control.Permission to conduct the study was obtained from the Provincial Department of Health and the managers of the institutions where the study was conducted. Recommendations for dealing with the identified factors have been formulated.

    Full Text Available Question: Does exercise improve postprandial glycaemic control in women diagnosed with gestational diabetes mellitus? Design: A systematic review of randomised trials. Participants: Pregnant women diagnosed with gestational diabetes mellitus. Intervention: Exercise, performed more than once a week, sufficient to achieve an aerobic effect or changes in muscle metabolism. Outcome measures: Postprandial blood glucose, fasting blood glucose, glycated haemoglobin, requirement for insulin, adverse events and adherence. Results: This systematic review identified eight randomised, controlled trials involving 588 participants; seven trials (544 participants had data that were suitable for meta-analysis. Five trials scored ≥ 6 on the PEDro scale, indicating a relatively low risk of bias. Meta-analysis showed that exercise, as an adjunct to standard care, significantly improved postprandial glycaemic control (MD –0.33 mmol/L, 95% CI –0.49 to –0.17 and lowered fasting blood glucose (MD –0.31 mmol/L, 95% CI –0.56 to –0.05 when compared with standard care alone, with no increase in adverse events. Effects of similar magnitude were found for aerobic and resistance exercise programs, if performed at a moderate intensity or greater, for 20 to 30 minutes, three to four times per week. Meta-analysis did not show that exercise significantly reduced the requirement for insulin. All studies reported that complications or other adverse events were either similar or reduced with exercise. Conclusion: Aerobic or resistance exercise, performed at a moderate intensity at least three times per week, safely helps to control postprandial blood glucose levels and other measures of glycaemic control in women diagnosed with gestational diabetes mellitus.

  10. Understanding barriers to glycaemic control from the patient's perspective

    Janes R

    2013-06-01

    Full Text Available INTRODUCTION: To better understand barriers to glycaemic control from the patient's perspective. METHODS: An interpretative phenomenological approach was used to study the experiences of 15 adults with Type 2 diabetes. Participants each gave a semi-structured interview of their experiences of living with diabetes. Interviews were transcribed, and themes extracted and organised using a patientcentred framework. FINDINGS: Participants' stories confirmed many of the barriers in the literature, particularly those related to context, such as family, finances, work. Barriers also related to negative emotional reactions to diabetes: fear of new events (diagnosis, starting pills/insulin; guilt about getting diabetes and not controlling it; and shame about having diabetes. Barriers also related to unscientific beliefs and personal beliefs. There were additional barriers related to poor clinician-patient relationships. Overall, participants had a poor understanding of diabetes, and complained that their clinician simply 'told them what to do'. CONCLUSION: Using a patient-centred approach, this study identified many barriers to glycaemic control. We suggest that a key barrier is clinician ignorance of their patients' fears, beliefs, expectations, context; of what constitutes a positive therapeutic relationship; and of the limitations of a biomedical approach to patient non-adherence. Faced with both a worsening diabetes epidemic and increasing health care workforce shortages, clinicians urgently need to understand that it is they, not their patients, who must change their approach if diabetes care is to be improved.

  11. Addressing Inpatient Glycaemic Control with an Inpatient Glucometry Alert System

    J. N. Seheult

    2015-01-01

    Full Text Available Background. Poor inpatient glycaemic control has a prevalence exceeding 30% and results in increased length of stay and higher rates of hospital complications and inpatient mortality. The aim of this study was to improve inpatient glycaemic control by developing an alert system to process point-of-care blood glucose (POC-BG results. Methods. Microsoft Excel Macros were developed for the processing of daily glucometry data downloaded from the Cobas IT database. Alerts were generated according to ward location for any value less than 4 mmol/L (hypoglycaemia or greater than 15 mmol/L (moderate-severe hyperglycaemia. The Diabetes Team provided a weekday consult service for patients flagged on the daily reports. This system was implemented for a 60-day period. Results. There was a statistically significant 20% reduction in the percentage of hyperglycaemic patient-day weighted values >15 mmol/L compared to the preimplementation period without a significant change in the percentage of hypoglycaemic values. The time-to-next-reading after a dysglycaemic POC-BG result was reduced by 14% and the time-to-normalization of a dysglycaemic result was reduced from 10.2 hours to 8.4 hours. Conclusion. The alert system reduced the percentage of hyperglycaemic patient-day weighted glucose values and the time-to-normalization of blood glucose.

    Full Text Available Objective. To identify the number of haemodialysis patients with diabetes in a large NHS Trust, their current glycaemic control, and the impact on other renal specific outcomes. Design. Retrospective, observational, cross-sectional study. Methods. Data was collected from an electronic patient management system. Glycaemic control was assessed from HbA1c results that were then further adjusted for albumin (Alb and haemoglobin (Hb. Interdialytic weight gains were analysed from weights recorded before and after dialysis, 2 weeks before and after the most recent HbA1c date. Amputations were identified from electronic records. Results. 39% of patients had poor glycaemic control (HbA1c > 8%. Adjusted HbA1c resulted in a greater number of patients with poor control (55%. Significant correlations were found with interdialytic weight gains (P<0.02, r=0.14, predialysis sodium (P<0.0001, r=-1.9, and predialysis bicarbonate (P<0.02, r=0.12. Trends were observed with albumin and C-reactive protein. Patients with diabetes had more amputations (24 versus 2. Conclusion. Large number of diabetic patients on haemdialysis have poor glycaemic control. This may lead to higher interdialytic weight gains, larger sodium and bicarbonate shifts, increased number of amputations, and possibly increased inflammation and decreased nutritional status. Comprehensive guidelines and more accurate long-term tests for glycaemic control are needed.

  13. Glycaemic Control and Associated Self-Management Behaviours in Diabetic Outpatients: A Hospital Based Observation Study in Lusaka, Zambia

    2016-01-01

    Full Text Available Background. The control of diabetes mellitus depends on several factors that also include individual lifestyles. We assessed glycaemic control status and self-management behaviours that may influence glycaemic control among diabetic outpatients. Methods. This cross-sectional study among 198 consenting randomly selected patients was conducted at the University Teaching Hospital diabetic clinic between September and December 2013 in Lusaka, Zambia. A structured interview schedule was used to collect data on demographic characteristics, self-management behaviours, and laboratory measurements. Binary logistic regression analysis using IBM SPSS for Windows version 20.0 was carried out to predict behaviours that were associated with glycaemic control status. Results. The proportion of patients that had good glycaemic control status (HbA1c≤ 48 mmol/mol was 38.7% compared to 61.3% that had poor glycaemic control status (HbA1c≥ 49 mmol/mol. Adherence to antidiabetic treatment and fasting plasma glucose predicted glycaemic control status of the patients. However, self-blood glucose monitoring, self-blood glucose monitoring means and exercise did not predict glycaemic control status of the patients.  Conclusion. We find evidence of poor glycaemic control status among most diabetic patients suggesting that health promotion messages need to take into account both individual and community factors to promote behaviours likely to reduce nonadherence.

  17. Glycated albumin is the preferred marker for assessing glycaemic control in advanced chronic kidney disease.

    Vos, Frederiek E; Schollum, John B; Walker, Robert J

    2011-12-01

    Diabetic nephropathy is the most common aetiology of end-stage kidney disease (ESKD). Strict glycaemic control reduces the development and progression of diabetes-related complications, and there is evidence that improved metabolic control improves outcomes in diabetic subjects with advanced chronic kidney disease (CKD). Glycaemic control in people with kidney disease is complex. Changes in glucose and insulin homeostasis may occur as a consequence of loss of kidney function and dialysis. The reliability of measures of long-term glycaemic control is affected by CKD and the accuracy of glycated haemoglobin (HbA1c) in the setting of CKD and ESKD is questioned. Despite the altered character of diabetes in CKD, current guidelines for diabetes management are not specifically adjusted to this patient group. The validity of indicators of longer term glycaemic control has been the focus of increased recent research. This review discusses the current understanding of commonly used indicators of metabolic control (HbA1c, fructosamine, glycated albumin) in the setting of advanced CKD (Stages 4 and 5, glomerular filtration rate <30 mL/min/1.73m(2)).

  18. The impact of improved glycaemic control with GLP-1 receptor agonist therapy on diabetic retinopathy.

    2014-03-01

    Rapid improvement in glycaemic control with GLP-1 receptor agonist (RA) therapy has been reported to be associated with significant progression of diabetic retinopathy. This deterioration is transient, and continuing GLP-1 RA treatment is associated with reversal of this phenomenon. Pre-existent maculopathy, higher grade of retinopathy and longer duration of diabetes may be risk factors for persistent deterioration.

  2. Daily energy expenditure, cardiorespiratory fitness and glycaemic control in people with type 1 diabetes.

    John Joseph Valletta

    Full Text Available OBJECTIVE: Encouraging daily physical activity improves cardiorespiratory fitness and many cardiovascular risk factors. However, increasing physical activity often creates a challenge for people with type 1 diabetes, because of difficulties maintaining euglycemia in the face of altered food intake and adjustments to insulin doses. Our aim was to examine the triangular relationship between glucose control measured by continuous glucose monitoring system (CGMS, objective measures of total daily energy expenditure (TEE recorded by a multi-sensory monitoring device, and cardiorespiratory fitness (CRF, in free-living subjects with type 1 diabetes. RESEARCH DESIGN AND METHODS: Twenty-three individuals (12 women with type 1 diabetes who were free from micro- and macrovascular complications were recruited. TEE and glucose control were monitored simultaneously for up to 12 days, using a multi-sensory device and CGMS respectively. CRF was recorded as V02 max from a maximal treadmill test with the Bruce protocol. RESULTS: Subjects (mean±SD were aged 37±11 years, with BMI = 26.5±5.1 kg.m⁻², HbA1c = 7.7±1.3% (61±14 mmol/mol and V02 max (ml.min⁻¹.kg⁻¹  = 39.9±8.4 (range 22.4-58.6. TEE (36.3±5.5 kcal.kg⁻¹.day⁻¹ was strongly associated with CRF(39.9±8.4 ml.min⁻¹.kg⁻¹ independently of sex (r = 0.63, p<0.01. However, neither TEE (r = -0.20, p = 0.36 nor CRF (r = -0.20, p = 0.39; adjusted for sex, were significantly associated with mean glycaemia measured by CGMS. CONCLUSION: Higher levels of energy expenditure (due to a more active lifestyle are associated with increased cardiorespiratory fitness, but not necessarily better glycaemic control. Since increased levels of energy expenditure and good glycaemic control are both needed to protect against diabetes-related complications our data suggest they need to be achieved independently.

  4. Insulin analogues: have they changed insulin treatment and improved glycaemic control?

    Madsbad, Sten

    2002-01-01

    To improve insulin therapy, new insulin analogues have been developed. Two fast-acting analogues with a more rapid onset of effect and a shorter duration of action combined with a low day-to-day variation in absorption rate are now available. Despite this favourable time-action profile most studies....... This is probably the main explanation for the absence of improvement in overall glycaemic control when compared with regular human insulin. A tendency to a reduction in hypoglycaemic events during treatment with fast-acting analogues has been observed in most studies. Recent studies have indicated that NPH insulin...... administered several times daily at mealtimes can improve glycaemic control without increasing the risk of hypoglycaemia. The fast-acting analogues are now also available as insulin mixed with NPH. Insulin glargine is a new long-acting insulin which is soluble and precipitates after injection, resulting...

  5. [Adjunctive therapies to glycaemic control of type 1 diabetes mellitus].

    Gabbay, Mônica de A Lima

    2008-03-01

    Since Diabetes Control and Complications Trial (DCCT), intensive therapy has been directed at achieving glucose and glycosylated hemoglobin (HbA1c) values as close to normal as possible regarding safety issues. However, hyperglycemia (especially postprandial hyperglycemia) and hypoglicemia continue to be problematic in the management of type 1 diabetes. The objective of associating other drugs to insulin therapy is to achieve better metabolic control lowering postprandial blood glucose levels. Adjunctive therapies can be divided in four categories based on their mechanism of action: enhancement of insulin action (e.g. the biguanides and thiazolidinediones), alteration of gastrointestinal nutrient delivery (e.g. acarbose and amylin) and other targets of action (e.g. pirenzepine, insulin-like growth factor I and glucagon-like peptide-1). Many of these agents have been found to be effective in short-term studies with decreases in HbA1c of 0.5-1%, lowering postprandial blood glucose levels and decreasing daily insulin doses.

    2015-09-01

    Full Text Available Purpose: Dietary modification in association with life style changes is important in the management of the diabetes. Cereals account for as much as 77% of total caloric consumption in most African diets. Corn which is the largest cultivated cereal crop in Nigeria is prepared as a meal in many forms. The objective of this study was to assess the glycaemic responses to different preparations of corn meals. Material and Method: The design was a quasi-experimental with a total of 32 participants, 16 subjects with type diabetes and 16 age-and sex-matched non-diabetic control subjects. After an overnight fast, the participants were given corn meals to eat and had their blood sample collected every 30 minutes for over a 2 hour period for the assessment of blood sugar level and estimation of glycaemic responses. This was repeated weekly till the glycaemic index (GI and plasma sugar level response to the different test corn meal preparation, such as boiled corn, roasted corn, pap and cornflakes had been assessed. Results: All the different corn meal preparations had high GI, with corn flakes having the highest GI and pap the lowest. The GI for the corn meals in the non-diabetic were; pap 71.7±14.4%, roasted corn 76.5±14.9%, boiled corn 82.2±14.9% and cornflakes 88.1±14.4%. Discussion: Methods of preparing a meal from corn affect glycaemic response. Turk Jem 2015; 19: 79-82

  8. Glycaemic index and glycaemic load of breakfast predict cognitive function and mood in school children: a randomised controlled trial.

    Micha, Renata; Rogers, Peter J; Nelson, Michael

    2011-11-01

    The macronutrient composition of a breakfast that could facilitate performance after an overnight fast remains unclear. As glucose is the brain's major energy source, the interest is in investigating meals differing in their blood glucose-raising potential. Findings vary due to unaccounted differences in glucoregulation, arousal and cortisol secretion. We investigated the effects of meals differing in glycaemic index (GI) and glycaemic load (GL) on cognition and mood in school children. A total of seventy-four school children were matched and randomly allocated either to the high-GL or low-GL group. Within each GL group, children received high-GI and low-GI breakfasts. Cognitive function (CF) and mood were measured 95-140 min after breakfast. Blood glucose and salivary cortisol were measured at baseline, before and after the CF tests. Repeated-measures ANOVA was used to identify differences in CF, mood, glucose and cortisol levels between the breakfasts. Low-GI meals predicted feeling more alert and happy, and less nervous and thirsty (P meals predicted feeling more confident, and less sluggish, hungry and thirsty (P meals increased glucose levels 90 min after breakfast, and high-GI meals increased cortisol levels (P meals predicted better declarative-verbal memory (P = 0·03), and high-GI meals better vigilance (P < 0·03); observed GI effects were valid across GL groups. GI effects on cognition appear to be domain specific. On balance, it would appear that the low-GI high-GL breakfast may help to improve learning, and of potential value in informing government education policies relating to dietary recommendations and implementation concerning breakfast.

  9. Higher body mass index and lower intake of dairy products predict poor glycaemic control among Type 2 Diabetes patients in Malaysia

    Shu, Ping Soon; Chan, Yoke Mun; Huang, Soo Lee

    2017-01-01

    This cross-sectional study was designed to determine factors contributing to glyceamic control in order to provide better understanding of diabetes management among Type 2 Diabetes patients. A pre-tested structured questionnaire was used to obtain information on socio-demographic and medical history. As a proxy measure for glycaemic control, glycosylated haemoglobin (HbA1c) was obtained as secondary data from the medical reports. Perceived self-care barrier on diabetes management, diet knowledge and skills, and diet quality were assessed using pretested instruments. With a response rate of 80.3%, 155 subjects were recruited for the study. Mean HbA1c level of the subjects was 9.02 ± 2.25% with more than 70% not able to achieve acceptable level in accordance to WHO recommendation. Diet quality of the subjects was unsatisfactory especially for vegetables, fruits, fish and legumes as well as from the milk and dairy products group. Higher body mass index (BMI), poorer medication compliance, lower diet knowledge and skill scores and lower intake of milk and dairy products contributed significantly on poor glycaemic control. In conclusion, while perceived self-care barriers and diet quality failed to predict HbA1c, good knowledge and skill ability, together with appropriate BMI and adequate intake of dairy products should be emphasized to optimize glycaemic control among type 2 diabetes patients.

    2015-01-01

    Full Text Available Introduction. Obesity and diabetes are difficult to treat in public clinics. We sought to determine the effectiveness of the Metabolic Rehabilitation Program (MRP in achieving long-term weight loss and improving glycaemic control versus “best practice” diabetes clinic (DC in obese patients using a retrospective cohort study. Methods. Patients with diabetes and BMI > 30 kg/m2 who attended the MRP, which consisted of supervised exercise and intense allied health integration, or the DC were selected. Primary outcomes were improvements in weight and glycaemia with secondary outcomes of improvements in blood pressure and lipid profile at 12 and 30 months. Results. Baseline characteristics of both cohorts (40 MRP and 40 DC patients were similar at baseline other than age (63 in MRP versus 68 years in DC, P=0.002. At 12 months, MRP patients lost 7.65 ± 1.74 kg versus 1.76 ± 2.60 kg in the DC group (P<0.0001 and 9.70 ± 2.13 kg versus 0.98 ± 2.65 kg at 30 months (P<0.0001. Similarly, MRP patients had significant absolute reductions in %HbA1c at 30 months versus the DC group (−0.86 ± 0.31% versus 0.12% ± 0.33%, P<0.038, with nonsignificant improvements in lipids and blood pressure in MRP patients. Conclusion. Further research is needed to establish the MRP as an effective strategy for achieving sustained weight loss and improving glycaemic control in obese patients with type 2 diabetes.

  12. What are the preferred strategies for control of glycaemic variability in patients with type 2 diabetes mellitus?

    Zenari, L; Marangoni, A

    2013-09-01

    The aim of therapy in type 2 diabetes in terms of blood glucose control is to reduce to target levels HbA1c and to reduce glycaemic variability in order to avoid both hypoglycaemia and wide excursions of postprandial glucose. The first approach to reduce glycaemic variability should consider a dietary and behavioural approach aiming to limit the glycaemic index and the glycaemic load of food and the prescription and implementation of a physical activity plan appropriate for the subject. From the pharmacological point of view, the diabetes specialist has now a much richer therapeutic armamentarium. The therapeutic algorithms can help the physician to choose the most appropriate drug. The traditional approach involves: i) metformin, acting mainly on fasting blood glucose; ii) sulphonylureas, that have shown a number of drawbacks, including the high risk of hypoglycemia; iii) pioglitazone, with a substantial effect on fasting and postprandial glucose and a low risk of hypoglycaemia; iv) insulin, that can be utilized with the basal or prandial approach. The new drugs belonging to the class of dipeptidyl peptidase-4 inhibitors have shown the reduction of postprandial glucose, a neutral effect on weight increase, a good safety profile and preliminary positive cardiovascular effects. When excess weight prevails, the glucagon-like peptide-1 agonists may be the preferred choice for their effect on weight reduction, reduction of hyperinsulinism and glycaemic variability.

    AIM To provide an update on glycaemic control inEuropean patients with type 2 diabetes mellitus (T2DM).We present the Greek population data of the study.METHODS: An observational multicenter, cross-sectionalstudy evaluating glycaemic control and a range of otherclinical and biological measures as well as quality of life(QoL) and treatment satisfaction in 375 patients withT2DM enrolled by 25 primary care sites from Greece.RESULTS: The mean age of the patients was 63.5years and the male/female ratio 48.9%/51.1%. 79.7%of the patients exerted none or light physical activity,82.4% were overweight or obese and 32.9% did notmeet HbA1c target of less than 7.0% (53 mmol/mol).Patients reported high satisfaction to continue withtreatment, high satisfaction with administered treatmentand increased willingness to recommend treatmentto others (mean Diabetes Treatment SatisfactionQuestionnaire score 29.1 ± 5.6). However, 80% of thepatients reported that their QoL would be better withoutdiabetes. Finally, the most challenging parameterreported was the lack of freedom to eat and drink.CONCLUSION: This analysis of the Greek Panoramastudy results showed that a considerable percentageof T2DM patients in Greece do not achieve glycaemictarget levels, despite the favourably reported patientsatisfaction from administered therapy. Additionally, themajority of primary care T2DM patients in Greece depictthe negative effect of the disease in their QoL.

    The polyol isomalt (Palatinit) is a very low glycaemic sugar replacer. The effect of food supplemented with isomalt instead of higher glycaemic ingredients like sucrose and/or starch hydrolysates on metabolic control in patients with type 2 diabetes was examined in this open study. Thirty-three patients with type 2 diabetes received a diet with foods containing 30 g/d isomalt instead of higher-glycaemic carbohydrates for 12 weeks. Metformin and/or thiazolidindiones were the only concomitant oral antidiabetics allowed during the study. Otherwise, the participants maintained their usual diet during the test phase, but were instructed to refrain from additional sweetened foods. Before start, after 6 weeks and 12 weeks (completion of the study), blood samples were taken and analysed for clinical routine parameters, metabolic, and risk markers. Thirty-one patients completed the study. The test diet was well accepted and tolerated. After 12 weeks, significant reductions were observed for: glycosylated haemoglobin, fructosamine, fasting blood glucose, insulin, proinsulin, C-peptide, insulin resistance (HOMA-IR), and oxidised LDL (an atherosclerosis risk factor). In addition, significant lower nonesterified fatty acid concentrations were found in female participants. Routine blood measurements and blood lipids remained unchanged. The substitution of glycaemic ingredients by isomalt and the consequent on reduction of the glycaemic load within otherwise unchanged diet was accompanied by significant improvement in the metabolic control of diabetes. The present study is in agreement with findings of previous reported studies in human subjects demonstrating beneficial effects of low glycaemic diets on glucose metabolism in patients with diabetes mellitus type 2.

    2014-11-01

    Full Text Available Objective: To compare the quality of care received by patients with diabetes in public primary care clinics in 2012 with that reported in 1995. Methods: Patient records were audited at six randomly selected Type III health centres in the South East Health Region of Jamaica. The 2012 audit data were compared with published data from a similar audit conducted in 1995. Quality of care measures included timely screening tests and counselling of the patients. Fasting and postprandial glucose tests were used to assess glycaemic control. Results: Two hundred and forty-two patient records were analysed in 2012, and 185 in 1995. In 2012, 88% of patients were weighed within the last year compared with 43% in 1995. Advice on physical activity increased from 1% to 60% and on dietary practices from 6% to 79%. No patient had done the HBA1C in 1995 compared to 38% in 2012. In 1995, 66% had blood glucose measured at a laboratory during the last year while in 2012, 60% had a laboratory test and 90% were tested at the clinic by glucometer. Blood pressure control increased from 19% in 1995 to 41% in 2012 (p < 0.001. Poor glucose control was recorded among 61% of patients in 1995 compared with 68% in 2012. Conclusions: There was no improvement in glycaemic control. Health providers and patients must work together to improve patient outcomes. This will involve closer patient monitoring, treatment intensification where indicated, and the adoption of lifestyle practices that can lead to better control.

    Association (DDA) completed the Hospital Anxiety and Depression Scale. Demographic and clinical characteristics were obtained using medical records (out-patients) or self-report (DDA). RESULTS: After controlling for number of complications, years of education and body mass index, depression showed significant......, low positive correlations with HbA(1c) in three of the four female samples and in one of the four male samples. Only for out-patients with Type 2 diabetes was the correlation between HbA(1c) and depression significantly higher for women when compared with men (0.19 vs. 0.04; P = 0.02). CONCLUSIONS......: The association between depression and HbA1c may be stronger in women with Type 2 diabetes. Oestrogen levels and self-care behaviours may play a mediating role in this association. Further research is required before we can conclude that the association between symptoms of depression and glycaemic control differs...

    Diurnal carbohydrate and fat distribution modulates glycaemic control in rodents. In humans, the optimal timing of both macronutrients and its effects on glycaemic control after prolonged consumption are not studied in detail. In this cross-over trial, 29 non-obese men were randomized to two four-week diets: (1) carbohydrate-rich meals until 13.30 and fat-rich meals between 16.30 and 22.00 (HC/HF) versus (2) inverse sequence of meals (HF/HC). After each trial period two meal tolerance tests were performed, at 09.00 and 15.40, respectively, according to the previous intervention. On the HF/HC diet, whole-day glucose level was increased by 7.9% (p = 0.026) in subjects with impaired fasting glucose and/or impaired glucose tolerance (IFG/IGT, n = 11), and GLP-1 by 10.2% (p = 0.041) in normal glucose-tolerant subjects (NGT, n = 18). Diet effects on fasting GLP-1 (p = 0.009) and PYY (p = 0.034) levels were observed in IFG/IGT, but not in NGT. Afternoon decline of glucose tolerance was more pronounced in IFG/IGT and associated with a stronger decrease of postprandial GLP-1 and PYY levels, but not with changes of cortisol rhythm. In conclusion, the HF/HC diet shows an unfavourable effect on glycaemic control in IFG/IGT, but not in NGT subjects. Consequently, large, carbohydrate-rich dinners should be avoided, primarily by subjects with impaired glucose metabolism. PMID:28272464

  1. The Health Economic Value of Changes in Glycaemic Control, Weight and Rates of Hypoglycaemia in Type 1 Diabetes Mellitus

    McEwan, Phil; Bennett, Hayley; Fellows, Jonathan; Priaulx, Jennifer; Bergenheim, Klas

    2016-01-01

    Aims Therapy-related consequences of treatment for type 1 diabetes mellitus (T1DM), such as weight gain and hypoglycaemia, act as a barrier to attaining optimal glycaemic control, indirectly influencing the incidence of vascular complications and associated morbidity and mortality. This study quantifies the individual and combined contribution of changes in hypoglycaemia frequency, weight and HbA1c to predicted quality-adjusted life-years (QALYs) within a T1DM population. Materials and methods We describe the Cardiff Type 1 Diabetes (CT1DM) Model, originally informed by the Diabetes Control and Complications Trial (DCCT) and updated with the Epidemiology of Diabetes Interventions and Complications (EDIC) study and Swedish National Diabetes Registry for microvascular and cardiovascular complications respectively. We report model validation results and the QALY impact of HbA1c, weight and hypoglycaemia changes. Results Validation results demonstrated coefficients of determination for clinical endpoints of R2 = 0.863 (internal R2 = 0.999; external R2 = 0.823), costs R2 = 0.980 and QALYs R2 = 0.951. Achieving and maintaining a 1% HbA1c reduction was estimated to provide 0.61 additional discounted QALYs. Weight changes of ±1kg, ±2kg or ±3kg led to discounted QALY changes of ±0.03, ±0.07 and ±0.10 respectively, while modifying hypoglycaemia frequency by -10%, -20% or -30% resulted in changes of -0.05, -0.11 and -0.17. The differences in discounted costs, life-years and QALYs associated with HbA1c 6% versus 10% were -£19,037, 2.49 and 2.35 respectively. Conclusions Using a model updated with contemporary epidemiological data, this study presents an outcome-focused perspective to assessing the health economic consequences of differing levels of glycaemic control in T1DM with and without weight and hypoglycaemia effects.

    Background Diabetes mellitus has become epidemic in recent years in China.We investigated the prevalence of hyperglycaemia and inadequate glycaemic control among type 2 diabetic inpatients from ten university teaching hospitals in Guangdong Province,China. Methods Inadequate glycaemic control in diabetic patients was defined as HbA1c(≥)6.5%.Therapeutic regimens included no-intervention,lifestyle only,oral antiglycemic agents(OA),insulin plus OA(insulin+OA),or insulin only. Antidiabetic managements included monotherapy,double therapy,triple or quadruple therapy. Results Among 493 diabetic inpatients with known history,75%had HbA1c≥6.5%.Inadequate glucose control rates were more frequently seen in patients on insulin+OA regimen(97%) than on OA regimen(71%)(P<O.001),and more frequent in patients on combination therapy(81%-96%)than monotherapy(75%)(P<0.05).Patients on insulin differed significantly from patients on OA by mean HbA1c,glycemic control rate,diabetes duration,microvascular complications,and BMI(P<0.01). Conclusions This study showed that glycaemic control of type 2 diabetic patients deteriorated for patients who received insulin and initiation time of insulin was usually delayed.It is up to clinicians to move from the traditional stepwise therapy to a more active and early combination antidiabetic therapy to provide better glucose control.

  4. Association of low density lipoprotein levels and glycaemic control in type-2 diabetes mellitus

    Yathish TR.

    2010-01-01

    Full Text Available Earlier diabetes mellitus (DM was thought to be a disease of carbohydrate metabolism. Looking at the effects of insulin deficiency on carbohydrate and lipid metabolism, diabetes mellitus is now being called more a disease of lipid metabolism than carbohydrate metabolism. A cross-sectional study was conducted during March 2005 to March 2006 to study the low-density lipoproteins (LDL levels in diabetes mellitus and its relation to glycaemic control. LDL levels were estimated. Comparison of lipid levels were made between group of diabetic patients with glycated hemoglobin less than 8.0% and a group of diabetic patients with glycated hemoglobin more than 8.0% and the controls. The lipid fractions i.e. total cholesterol (TC, triglycerides (TG, and low-density lipoprotein (LDL levels were higher in the poorly controlled diabetes patients as compared to well controlled diabetic patients and nondiabetic patients. Increased levels of low-density lipoprotein may be a contributory factor to the high risk of atherosclerosis induced coronary artery disease observed in diabetes mellitus patients. Reduction of blood glucose levels is likely to reduce low density lipoprotein levels and the risk of complication, with the lowest risk being in those with glycosylated hemoglobin values in the normal range ie. Less than 8.0%

  5. The gut microbiota modulates glycaemic control and serum metabolite profiles in non-obese diabetic mice.

    Greiner, Thomas U; Hyötyläinen, Tuulia; Knip, Mikael; Bäckhed, Fredrik; Orešič, Matej

    2014-01-01

    Islet autoimmunity in children who later progress to type 1 diabetes is preceded by dysregulated serum metabolite profiles, but the origin of these metabolic changes is unknown. The gut microbiota affects host metabolism and changes in its composition contribute to several immune-mediated diseases; however, it is not known whether the gut microbiota is involved in the early metabolic disturbances in progression to type 1 diabetes. We rederived non-obese diabetic (NOD) mice as germ free to explore the potential role of the gut microbiota in the development of diabetic autoimmunity and to directly investigate whether the metabolic profiles associated with the development of type 1 diabetes can be modulated by the gut microbiota. The absence of a gut microbiota in NOD mice did not affect the overall diabetes incidence but resulted in increased insulitis and levels of interferon gamma and interleukin 12; these changes were counterbalanced by improved peripheral glucose metabolism. Furthermore, we observed a markedly increased variation in blood glucose levels in the absence of a microbiota in NOD mice that did not progress to diabetes. Additionally, germ-free NOD mice had a metabolite profile similar to that of pre-diabetic children. Our data suggest that germ-free NOD mice have reduced glycaemic control and dysregulated immunologic and metabolic responses.

  6. Assessing Diabetes Self-Management with the Diabetes Self-Management Questionnaire (DSMQ Can Help Analyse Behavioural Problems Related to Reduced Glycaemic Control.

    Andreas Schmitt

    Full Text Available To appraise the Diabetes Self-Management Questionnaire (DSMQ's measurement of diabetes self-management as a statistical predictor of glycaemic control relative to the widely used SDSCA.248 patients with type 1 diabetes and 182 patients with type 2 diabetes were cross-sectionally assessed using the two self-report measures of diabetes self-management DSMQ and SDSCA; the scales were used as competing predictors of HbA1c. We developed a structural equation model of self-management as measured by the DSMQ and analysed the amount of variation explained in HbA1c; an analogue model was developed for the SDSCA.The structural equation models of self-management and glycaemic control showed very good fit to the data. The DSMQ's measurement of self-management showed associations with HbA1c of -0.53 for type 1 and -0.46 for type 2 diabetes (both P < 0.001, explaining 21% and 28% of variation in glycaemic control, respectively. The SDSCA's measurement showed associations with HbA1c of -0.14 (P = 0.030 for type 1 and -0.31 (P = 0.003 for type 2 diabetes, explaining 2% and 10% of glycaemic variation. Predictive power for glycaemic control was significantly higher for the DSMQ (P < 0.001.This study supports the DSMQ as the preferred tool when analysing self-reported behavioural problems related to reduced glycaemic control. The scale may be useful for clinical assessments of patients with suboptimal diabetes outcomes or research on factors affecting associations between self-management behaviours and glycaemic control.

    2013-09-01

    As skin autofluorescence (AF) can assess subcutaneous accumulation of fluorescent advanced glycation end-products (AGEs), this study aimed to investigate whether it was linked to glycaemic control and complications in patients with type 1 diabetes mellitus (T1DM). Using the AGE Reader™, AF was measured in T1DM patients referred to Haut-Levêque Hospital (Bordeaux, France); data on their HbA1c levels measured every 6months as far back as the last 5years were also collected. The association of AF with the patients' past glucose control, based on their latest HbA1c values, and the means of the last five and 10 HbA1c values, and with diabetic complications was also examined by linear regression analysis. The sample included 300 patients: 58% were male; the mean age was 49 (SD 17) years and the mean diabetes duration was 21 (SD 13) years. The median skin AF measurement was 2.0 [25th-75th percentiles: 1.7-2.4] arbitrary units (AU), and this was associated with age (β=0.15 per 10years, P<0.001) and diabetes duration (β=0.17 per 10years, P<0.001). After adjusting for age and estimated glomerular filtration rate (eGFR), the skin AF measurement was also related to the means of the last five and 10 HbA1c values (β=0.10 per 1% of HbA1c, P=0.005, and β=0.13 per 1% of HbA1c, P=0.001, respectively). In addition, the skin AF was associated with retinopathy (P<0.001), albuminuria (P<0.001) and decreased eGFR (P<0.001). In conclusion, the skin AF is related to the long-term glucose control and diabetic complications.

    The aim of this study was to evaluate the ultrasound characteristics of the seminal vesicles (SVs) of infertile patients with diabetes mellitus (DM) and diabetic neuropathy (DN) and to investigate possible changes in ultrasound characteristics related to glycaemic control.To accomplish this,45 infertile patients with type 2 DM and symptomatic DN were selected.Twenty healthy fertile men and 20 patients with idiopathic oligoasthenoteratozoospermia without DM represented the control groups.DM patients were arbitrarily divided into three groups according to glycaemic control level (A=glycosylated haemoglobin <7%; B=glycosylated haemoglobin between 7% and 10%; C=glycosylated haemoglobin > 10%).Patients underwent prostate-vesicular transrectal ultrasonography and sperm analysis.The following SV ultrasound parameters were recorded:(i) body antero-posterior diameter (APD); (ii) fundus APD; (iii) parietal thicknesses of the right and left SVs; and (iv) the number of polycyclic areas within both SVs.We then calculated the following parameters:(i) fundus/body (F/B) ratio; (ii) difference of the parietal thickness between the right and the left SV; and (iii) pre-and post-ejaculatory APD difference.All DM patients had a higher F/B ratio compared to controls (P<0.05).Group C had a higher F/B ratio compared to the other DM groups (P<0.05).All DM patients had a lower pre-and post-ejaculatory difference of the body SV APD compared to controls (P<0.05).Groups A and B had a similar pre-and post-ejaculatory difference of the body SV APD,whereas this difference was lower in Group C (P<0.05).In conclusion,infertile DM patients with DN showed peculiar SV ultrasound features suggestive of functional atony,and low glycaemic control was associated with greater expression of these features.

    Full Text Available Physical activity improves the regulation of glucose homeostasis in both type 2 diabetes (T2D patients and healthy individuals, but the effect on pancreatic β cell function is unknown. We investigated glycaemic control, pancreatic function and total fat mass before and after 8 weeks of low volume high intensity interval training (HIIT on cycle ergometer in T2D patients and matched healthy control individuals. Study design/method: Elderly (56 yrs±2, non-active T2D patients (n = 10 and matched (52 yrs±2 healthy controls (CON (n = 13 exercised 3 times (10×60 sec. HIIT a week over an 8 week period on a cycle ergometer. Participants underwent a 2-hour oral glucose tolerance test (OGTT. On a separate day, resting blood pressure measurement was conducted followed by an incremental maximal oxygen uptake (VO2max cycle ergometer test. Finally, a whole body dual X-ray absorptiometry (DXA was performed. After 8 weeks of training, the same measurements were performed. Results: in the T2D-group, glycaemic control as determined by average fasting venous glucose concentration (p = 0.01, end point 2-hour OGTT (p = 0.04 and glycosylated haemoglobin (p = 0.04 were significantly reduced. Pancreatic homeostasis as determined by homeostatic model assessment of insulin resistance (HOMA-IR and HOMA β cell function (HOMA-%β were both significantly ameliorated (p = 0.03 and p = 0.03, respectively. Whole body insulin sensitivity as determined by the disposition index (DI was significantly increased (p = 0.03. During OGTT, the glucose continuum was significantly reduced at -15 (p = 0.03, 30 (p = 0.03 and 120 min (p = 0.03 and at -10 (p = 0.003 and 0 min (p = 0.003 with an additional improvement (p = 0.03 of its 1st phase (30 min area under curve (AUC. Significant abdominal fat mass losses were seen in both groups (T2D: p = 0.004 and CON: p = 0.02 corresponding to a percentage change of -17.84%±5.02 and -9.66%±3.07, respectively.

  15. A randomised control trial of low glycaemic index carbohydrate diet versus no dietary intervention in the prevention of recurrence of fetal macrosomia.

    Walsh, Jennifer

    2010-04-23

    Abstract Background Maternal weight and maternal weight gain during pregnancy exert a significant influence on infant birth weight and the incidence of macrosomia. Fetal macrosomia is associated with an increase in both adverse obstetric and neonatal outcome, and also confers a future risk of childhood obesity. Studies have shown that a low glycaemic diet is associated with lower birth weights, however these studies have been small and not randomised 1 2 . Fetal macrosomia recurs in a second pregnancy in one third of women, and maternal weight influences this recurrence risk 3 . Methods\\/Design We propose a randomised control trial of low glycaemic index carbohydrate diet vs. no dietary intervention in the prevention of recurrence of fetal macrosomia. Secundigravid women whose first baby was macrosomic, defined as a birth weight greater than 4000 g will be recruited at their first antenatal visit. Patients will be randomised into two arms, a control arm which will receive no dietary intervention and a diet arm which will be commenced on a low glycaemic index diet. The primary outcome measure will be the mean birth weight centiles and ponderal indices in each group. Discussion Altering the source of maternal dietary carbohydrate may prove to be valuable in the management of pregnancies where there has been a history of fetal macrosomia. Fetal macrosomia recurs in a second pregnancy in one third of women. This randomised control trial will investigate whether or not a low glycaemic index diet can affect this recurrence risk.

  17. Effect of adjunct metformin treatment in patients with type-1 diabetes and persistent inadequate glycaemic control. A randomized study.

    Søren Søgaard Lund

    Full Text Available BACKGROUND: Despite intensive insulin treatment, many patients with type-1 diabetes (T1DM have longstanding inadequate glycaemic control. Metformin is an oral hypoglycaemic agent that improves insulin action in patients with type-2 diabetes. We investigated the effect of a one-year treatment with metformin versus placebo in patients with T1DM and persistent poor glycaemic control. METHODOLOGY/PRINCIPAL FINDINGS: One hundred patients with T1DM, preserved hypoglycaemic awareness and HaemoglobinA(1c (HbA(1c > or = 8.5% during the year before enrolment entered a one-month run-in on placebo treatment. Thereafter, patients were randomized (baseline to treatment with either metformin (1 g twice daily or placebo for 12 months (double-masked. Patients continued ongoing insulin therapy and their usual outpatient clinical care. The primary outcome measure was change in HbA(1c after one year of treatment. At enrolment, mean (standard deviation HbA(1c was 9.48% (0.99 for the metformin group (n = 49 and 9.60% (0.86 for the placebo group (n = 51. Mean (95% confidence interval baseline-adjusted differences after 12 months with metformin (n = 48 versus placebo (n = 50 were: HbA(1c, 0.13% (-0.19; 0.44, p = 0.422; Total daily insulin dose, -5.7 U/day (-8.6; -2.9, p<0.001; body weight, -1.74 kg (-3.32; -0.17, p = 0.030. Minor and overall major hypoglycaemia was not significantly different between treatments. Treatments were well tolerated. CONCLUSIONS/SIGNIFICANCE: In patients with poorly controlled T1DM, adjunct metformin therapy did not provide any improvement of glycaemic control after one year. Nevertheless, adjunct metformin treatment was associated with sustained reductions of insulin dose and body weight. Further investigations into the potential cardiovascular-protective effects of metformin therapy in patients with T1DM are warranted. TRIAL REGISTRATION: ClinicalTrials.gov NCT00118937.

  18. Automated bolus advisor control and usability study (ABACUS: does use of an insulin bolus advisor improve glycaemic control in patients failing multiple daily insulin injection (MDI therapy? [NCT01460446

    Cavan David A

    2012-10-01

    Full Text Available Abstract Background People with T1DM and insulin-treated T2DM often do not follow and/or adjust their insulin regimens as needed. Key contributors to treatment non-adherence are fear of hypoglycaemia, difficulty and lack of self-efficacy associated with insulin dose determination. Because manual calculation of insulin boluses is both complex and time consuming, people may rely on empirical estimates, which can result in persistent hypoglycaemia and/or hyperglycaemia. Use of automated bolus advisors (BA has been shown to help insulin pump users to more accurately meet prandial insulin dosage requirements, improve postprandial glycaemic excursions, and achieve optimal glycaemic control with an increased time within optimal range. Use of a BA containing an early algorithm based on sliding scales for insulin dosing has also been shown to improve HbA1c levels in people treated with multiple daily insulin injections (MDI. We designed a study to determine if use of an automated BA can improve clinical and psychosocial outcomes in people treated with MDI. Methods/design The Automated Bolus Advisor Control and Usability Study (ABACUS is a 6-month, prospective, randomised, multi-centre, multi-national trial to determine if automated BA use improves glycaemic control as measured by a change in HbA1c in people using MDI with elevated HbA1c levels (#62;7.5%. A total of 226 T1DM and T2DM participants will be recruited. Anticipated attrition of 20% will yield a sample size of 90 participants, which will provide #62;80% power to detect a mean difference of 0.5%, with SD of 0.9%, using a one-sided 5% t-test, with 5% significance level. Other measures of glycaemic control, self-care behaviours and psychosocial issues will also be assessed. Discussion It is critical that healthcare providers utilise available technologies that both facilitate effective glucose management and address concerns about safety and lifestyle. Automated BAs may help people using MDI to

    2014-07-01

    Full Text Available Pregnancy increases the risk of being overweight at a later time period, particularly when there is excessive gestational weight gain. There remains a paucity of data into the effect of low glycaemic index (GI pregnancy interventions postpartum. Aim: To examine the impact of a low glycaemic index diet during pregnancy on maternal diet 3 months postpartum. Methodology: This analysis examined the diet, weight and lifestyle of 460 participants of the ROLO study 3 months postpartum. Questionnaires on weight, physical activity, breastfeeding, supplement use, food label reading and dietary habits were completed. Results: The intervention group had significantly greater weight loss from pre-pregnancy to 3 months postpartum than the control group (1.3 vs. 0.1 kg, p = 0.022. The intervention group reported greater numbers following a low glycaemic index diet (p < 0.001 and reading food labels (p = 0.032 and had a lower glycaemic load (GL (128 vs. 145, p = 0.014 but not GI (55 vs. 55, p = 0.809 than controls. Conclusions: Low GI dietary interventions in pregnancy result in improved health-behaviours and continued reported compliance at 3 months postpartum possibly through lower dietary GL as a result of portion control. Greater levels of weight loss from pre-pregnancy to 3 months postpartum in the intervention group may have important positive implications for overweight and obesity.

    The effects of fish oil (FO) supplementation on glycaemic control are unclear, and positive effects may occur only when the phospholipid content of tissue membranes exceeds 14% as n-3 PUFA. Subjects (n 36, thirty-three completed) were paired based on metabolic parameters and allocated into a parallel double-blind randomised trial with one of each pair offered daily either 6 g of FO (3·9 g n-3 PUFA) or 6 g of maize oil (MO) for 9 months. Hyperinsulinaemic-euglycaemic-euaminoacidaemic (HIEGEAA) clamps (with [6,6 2H2 glucose]) were performed at the start and end of the intervention. Endogenous glucose production (EGP) and whole-body protein turnover (WBPT) were each measured after an overnight fast. The primary outcome involved the effect of oil type on insulin sensitivity related to glycaemic control. The secondary outcome involved the effect of oil type on WBPT. Subjects on FO (n 16) had increased erythrocyte n-3 PUFA concentrations >14%, whereas subjects on MO (n 17) had unaltered n-3 PUFA concentrations at 9%. Type of oil had no effect on fasting EGP, insulin sensitivity or total glucose disposal during the HIEGEAA clamp. In contrast, under insulin-stimulated conditions, total protein disposal (P=0·007) and endogenous WBPT (P=0·001) were both increased with FO. In an associated pilot study (n 4, three completed), although n-3 PUFA in erythrocyte membranes increased to >14% with the FO supplement, the enrichment in muscle membranes remained lower (8%; Psupplementation with FO, at amounts near the safety limits set by regulatory authorities in Europe and the USA, did not alter glycaemic control but did have an impact on WBPT.

  4. Predicting self-care practices and glycaemic control using health belief model (HBM) in patients with insulin-treated diabetes in Malaysia

    Aris, Aishairma

    2016-01-01

    Background: The practice of diabetes self-care plays an important role in glycaemic control. However, not all patients with insulin-treated diabetes engage in their self-care activities. Although there is evidence that self-care practices in patients with insulin-treated diabetes can be understood and predicted by health beliefs proposed by Health Belief Model (HBM), little is known about adult patients due to several methodological weaknesses of previous studies. Furthermore, knowledge is la...

    Background Prevalence of inadequate glycaemic control among patients with type 2 diabetes mellitus (T2DM)remains high. We assessed glycaemic control in the real-life practice among people with T2DM in metropolises in China who were treated with oral antidiabetic drugs (OAD) alone and to determine factors associated with inadequate giycaemic control in this population.Methods An observational, cross-sectional multicentre study was conducted in 16 metropolitan medical centers.People with T2DM who had been followed-up before the index visit which occurred from January to September 2007 were included in the study. All subjects were ≥30 years of age at the time of T2DM diagnosis and had received monotherapy or combination therapy of OAD for at least 6 months. Demographic and clinical data were collected from medical records. The main study outcome was the inadequate glucose control rate, which was calculated by the proportion of patients with haemoglobin A1c (HbA1c) ≥6.5% detected on the index visit.Results In this cohort of 455 patients with T2DM whose mean age was 60.6 years and mean disease duration was 6.1 years, 45.5% had inadequate glycaemic control. The mean (SD) HbA1c was 6.7% (1.3). Multivariate Logistic regression showed that physical inactivity, disease duration >10 years, body mass index (BMI) ≥24 kg/m2, low homeostasis model assessment of β-cell function (HOMA-β) index, less frequency of medical visit and hypertriglyceridaemia were independent determinants of inadequate glycaemic control. Higher incidence of self-reported hypoglycemia experience (47.1% vs. 34.8%, P=0.008) and more fear of hypoglycemia quantified by Worry subscaie of the Hypoglycaemia Fear Survey (HFS) Ⅱ were happened in subjects with good glycemic control.Conclusion Approximately one half of these outpatients with T2DM from the metropolitan medical centers in China had inadequate glycaemic control treated with OAD alone, which raises the need for more effective educational and

  6. The zinc transporter, Slc39a7 (Zip7 is implicated in glycaemic control in skeletal muscle cells.

    Stephen A Myers

    Full Text Available Dysfunctional zinc signaling is implicated in disease processes including cardiovascular disease, Alzheimer's disease and diabetes. Of the twenty-four mammalian zinc transporters, ZIP7 has been identified as an important mediator of the 'zinc wave' and in cellular signaling. Utilizing siRNA targeting Zip7 mRNA we have identified that Zip7 regulates glucose metabolism in skeletal muscle cells. An siRNA targeting Zip7 mRNA down regulated Zip7 mRNA 4.6-fold (p = 0.0006 when compared to a scramble control. This was concomitant with a reduction in the expression of genes involved in glucose metabolism including Agl, Dlst, Galm, Gbe1, Idh3g, Pck2, Pgam2, Pgm2, Phkb, Pygm, Tpi1, Gusb and Glut4. Glut4 protein expression was also reduced and insulin-stimulated glycogen synthesis was decreased. This was associated with a reduction in the mRNA expression of Insr, Irs1 and Irs2, and the phosphorylation of Akt. These studies provide a novel role for Zip7 in glucose metabolism in skeletal muscle and highlight the importance of this transporter in contributing to glycaemic control in this tissue.

    2016-03-01

    Full Text Available BACKGROUND Diabetes mellitus is a metabolic disorder affecting almost all the organs by its micro and macrovascular complications. Like other organs the respiratory system is also affected by diabetic complications like microangiopathy. Very few studies investigated the complications and the relationship with the duration of the diabetes and glycaemic status. So in this point of view, we planned to study the effect of pulmonary function in our type 2 diabetic patients. AIMS AND OBJECTIVES To study the influence of glycaemic control (based on HbA1c levels on pulmonary function tests and the correlation between spirometric abnormalities and duration of diabetes in type 2 diabetic patients. MATERIALS AND METHODS 55 type 2 diabetic patients who gave informed consent were recruited. History regarding duration of diabetes, treatment, history suggestive of complications like neuropathy, retinopathy, nephropathy, regular sugar monitoring, exercise, etc. were recorded. BMI was calculated. Chest x-ray was taken for all patients. They underwent spirometry and the predicted and measured values of FEV1, FVC, FEV1/FVC, PEFR, FEF 25-75 for all the patients were recorded. After spirometry, HbA1c estimation was done using ion exchange resin method. Oneway ANOVA, correlation, paired and unpaired-t-test were used for analysis. RESULTS There was significant difference between the mean predicted FVC, FEV1, PEFR, and FEF 25-75, and measured values. The mean of measured spirometric values decreases as the HbA1c increases. There was reducing trend of the spirometric values as HbA1c increases, this was not statistically significant. The incidence of restrictive pattern was more common among the male patients compared with female patients but this was not statistically significant. DISCUSSION AND CONCLUSION: Restrictive pattern was more with increase in duration of diabetes. Out of 55 patients, 33 had probable restriction, 5 had moderate obstruction and 1 had severe

  10. Effect of orlistat on glycaemic control in overweight and obese patients with type 2 diabetes mellitus: a systematic review and meta-analysis of randomized controlled trials.

    Aldekhail, N M; Logue, J; McLoone, P; Morrison, D S

    2015-12-01

    Orlistat is an effective adjunctive treatment to lifestyle modifications in the treatment of obesity. While the majority of current evidence is on the effect of orlistat in obese patients without diabetes, some studies suggest that patients who are obese and have diabetes mellitus lose more weight and have greater improvements in diabetic outcomes when treated with orlistat plus a lifestyle intervention than when treated by lifestyle interventions alone. The aim of this study was to review the evidence of the effects of orlistat on glycaemic control in overweight and obese patients with type 2 diabetes. A systematic review of randomized controlled trials of orlistat in people with type 2 diabetes reporting diabetes outcomes in studies published between January 1990 and September 2013 was conducted. We searched for articles published in English in MEDLINE and EMBASE. Inclusion criteria included all randomized controlled trials of orlistat carried out on adult participants with a body mass index of 25 kg m(-2) or over diagnosed with type 2 diabetes, which reported weight change and at least one diabetic outcome. A total of 765 articles were identified out of which 12 fulfilled the inclusion criteria. The overall mean weight reduction (3, 6 and 12 months) in the orlistat group was -4.25 kg (95% CI: -4.5 to -3.9 kg). The mean weight difference between treatment and control groups was -2.10 kg (95% CI: -2.3 to -1.8 kg, P orlistat plus lifestyle intervention resulted in significantly greater weight loss and improved glycaemic control in overweight and obese patients with type 2 diabetes compared with lifestyle intervention alone.

    2014-01-01

    Full Text Available Background/Aim. An ideal insulin regimen for children and adolescents with type 1 diabetes mellitus (T1DM should be physiological, flexibile and predictable, protecting against hypoglycaemia. The aim of this study was to evaluate the influence of insulin analogues on glycaemic control and the occurrence of hypoglycaemic episodes in children and adolescents with T1DM. Methods. The study group consisted of 151 children and adolescents (90 boys, 61 girls treated with human insulins for at least 12 months before introducing insulin analogues. All the patients were divided into two groups: the group I consisted of 72 (47.7% patients treated with three injections of regular human insulin before meals and long-acting analogue (RHI/LA, and the group II of 79 (52.3% patients treated with a combination of rapid-acting and long-acting analogue (RA/LA. The levels of glycated hemoglobin (HbA1c and the number of hypoglycaemic episodes were assessed at the beginning of therapy with insulin analogues, and after 6 and 12 months. Results. The mean HbA1c was significantly lower in the group I (RHI/LA after 6 months (9.15% vs 8.20%, p < 0.001 and after 12 months (9.15% vs 8.13%, p < 0.001 as well as in the group II (RA/LA after 6 months (9.40% vs 8.24%, p < 0.001 and after 12 months of insulin analogues treatment (9.40% vs 8.38%, p < 0.001. The frequency of severe hypoglycaemia was significantly lower in both groups after 6 months (in the group I from 61.1% to 4.2% and in the group II from 54.4% to 1.3%, p < 0.001, and after 12 months (in the group I from 61.1% to 1.4% and in the group II from 54.4% to 1.3%, p < 0.001. Conclusion. Significantly better HbA1c values and lower risk of severe hypoglycaemia were established in children and adolescents with T1DM treated with insulin analogues.

    2013-01-01

    Aims/hypothesis We tested the hypothesis that age younger than 65 years at type 2 diabetes diagnosis is associated with worse subsequent glycaemic control. Methods A cross-sectional analysis of data from participants in the 2005–2010 National Health and Nutrition Examination Survey was performed. For adults with self-reported diabetes, we dichotomised age at diabetes diagnosis as younger (9.0% (75 mmol/mol). Secondary outcomes were HbA1c >8.0% (64 mmol/mol) and >7.0% (53 mmol/mol). We used multivariable logistic regression for analysis. Results Among 1,438 adults with diabetes, a higher proportion of those 9.0% (14.4% vs 2.5%, p 9.0% (OR 3.22, 95% CI 1.54, 6.72), HbA1c > 8.0% (OR 2.72, 95% CI 1.43, 5.16) and HbA1c >7.0% (OR 1.92, 95% CI 1.18, 3.11). The younger group reported fewer comorbidities, but were less likely to report good health (OR 0.54, 95% CI 0.36, 0.83). Conclusions/interpretation Younger age at type 2 diabetes diagnosis is significantly associated with worse subsequent glycaemic control. Because patients who are younger at diagnosis have fewer competing comorbidities and complications, safe, aggressive, individualised treatment could benefit this higher-risk group. PMID:23995472

    The glycaemic index (GI) concept was originally introduced to classify different sources of carbohydrate (CHO)-rich foods, usually having an energy content of >80 % from CHO, to their effect on post-meal glycaemia. It was assumed to apply to foods that primarily deliver available CHO, causing hyperglycaemia. Low-GI foods were classified as being digested and absorbed slowly and high-GI foods as being rapidly digested and absorbed, resulting in different glycaemic responses. Low-GI foods were found to induce benefits on certain risk factors for CVD and diabetes. Accordingly it has been proposed that GI classification of foods and drinks could be useful to help consumers make 'healthy food choices' within specific food groups. Classification of foods according to their impact on blood glucose responses requires a standardised way of measuring such responses. The present review discusses the most relevant methodological considerations and highlights specific recommendations regarding number of subjects, sex, subject status, inclusion and exclusion criteria, pre-test conditions, CHO test dose, blood sampling procedures, sampling times, test randomisation and calculation of glycaemic response area under the curve. All together, these technical recommendations will help to implement or reinforce measurement of GI in laboratories and help to ensure quality of results. Since there is current international interest in alternative ways of expressing glycaemic responses to foods, some of these methods are discussed.

  17. Bromocriptine improves glycaemic control and serum lipid profile in obese Type 2 diabetic subjects: a new approach in the treatment of diabetes.

    Cincotta; Meier; Cincotta Jr

    1999-10-01

    Bromocriptine, a potent dopamine D(2) receptor agonist, has been shown to reduce insulin resistance, glucose intolerance and hyperlipidaemia in both numerous animal studies and in Phase II studies. Bromocriptine has been used worldwide for over 20 years to treat Parkinson's disease, macroprolactinoma and other disorders; it has been found to be generally safe. We therefore investigated the possible beneficial effects of Ergoset(R) (Ergo Science Corp.), a new quick release formulation of bromocriptine, on glycaemic control and serum lipid profile in obese Type 2 diabetic subjects in two large Phase III studies. A large, randomised, double-blind placebo-controlled study was conducted in which Ergoset was given once daily at 8 am. (4.8 mg maximum dose) for 24 weeks as adjunctive therapy to sulphonylurea (485 subjects) to obese Type 2 diabetics held on a weight- maintaining diet. Treatment efficacy parameters included change from baseline in glycated haemoglobin A(1c) (HbA(1c)), fasting and post-prandial serum glucose, insulin, triglyceride and free fatty acid levels. Baseline glycated haemoglobin, fasting glucose, insulin, triglyceride and free fatty acid levels did not differ between treatment groups. and on average were 9.4 +/- 0.05%, 222 +/- 2 mg/dl, 24 +/- 1 µU/ml, 248 +/- 11 mg/dl, and 850 +/- 32 µEq/l, respectively. A similarly designed study of Ergoset as monotherapy in Type 2 diabetics (154 subjects) with similar baseline clinical characteristics was conducted. Addition of Ergoset treatment to sulphonylurea reduced percent glycated HbA(1c) by 0.55 (P fasting and post-prandial glucose by 23 and 26 mg/dl (P fasting and post-prandial triglycerides by 72 and 63 mg/dl (P fasting and post-prandial free fatty acids by 150 and 165 µEq/l (P < 0.05), relative to placebo. Twelve percent of all Ergoset subjects, compared to 3% of placebo subjects, withdrew from the study due to adverse events. The most common events causing withdrawal were nausea, dizziness, asthenia

    2016-01-01

    Objectives To assess trends in prescribing practices of antidiabetic agents and glycaemic control in patients with type 2 diabetes mellitus (T2DM). Design Cross-sectional analysis using yearly clinical data and antidiabetic treatments prescribed obtained from an electronic population database. Setting Primary healthcare centres, including the entire population attended by the Institut Català de la Salut in Catalonia, Spain, from 2007 to 2013. Participants Patients aged 31–90 years with a diagnosis of T2DM. Results The number of registered patients with T2DM in the database was 257 072 in 2007, increasing up to 343 969 in 2013. The proportion of patients not pharmacologically treated decreased by 9.7% (95% CI −9.48% to −9.92%), while there was an increase in the percentage of patients on monotherapy (4.4% increase; 95% CI 4.16% to 4.64%), combination therapy (2.8% increase; 95% CI 2.58% to 3.02%), and insulin alone or in combination (increasing 2.5%; 95% CI 2.2% to 2.8%). The use of metformin and dipeptidyl peptidase-IV inhibitors increased gradually, while sulfonylureas, glitazones and α-glucosidase inhibitors decreased. The use of glinides remained stable, and the use of glucagon-like peptide-1 receptor agonists was still marginal. Regarding glycaemic control, there were no relevant differences across years: mean glycated haemoglobin (HbA1c) value was around 7.2%; the percentage of patients reaching an HbA1c≤7% target ranged between 52.2% and 55.6%; and those attaining their individualised target from 72.8% to 75.7%. Conclusions Although the proportion of patients under pharmacological treatment increased substantially over time and there was an increase in the use of combination therapies, there have not been relevant changes in glycaemic control during the 2007–2013 period in Catalonia.

  19. Glucose- and glycaemic factor-lowering effects of probiotics on diabetes: a meta-analysis of randomised placebo-controlled trials.

    Sun, Jing; Buys, Nicholas J

    2016-04-14

    This meta-analysis examined the effect of probiotics on glucose and glycaemic factors in diabetes and its associated risk factors. All randomised-controlled trials published in English in multiple databases from January 2000 to June 2015 were systematically searched. Only studies that addressed glucose- and glycaemic-related factors as outcome variables were included. The main outcomes of interest in trials were mean changes in glucose, HbA1c, insulin and homoeostasis model assessment-estimated insulin resistance (HOMA-IR). Using the Physiotherapy Evidence Database (PEDro) scale to assess the quality of studies, a total of eleven studies with 614 subjects were included. The pooled mean difference and effect size with a 95% CI were extracted using a random-effect model. It was found that there are statistically significant pooled mean differences between the probiotics and the placebo-controlled groups on the reduction of glucose (-0·52 mmol/l, 95% CI -0·92, -0·11 mmol/l; P=0·01) and HbA1c (-0·32%, 95% CI -0·57, -0·07%; P=0·01). There was no statistically significant pooled mean difference between the probiotics and the placebo-controlled groups on the reduction of insulin (-0·48 µIU/ml, 95% CI -1·34, 0·38 µIU/ml; P=0·27) and HOMA-IR (pooled effect of -0·44, 95% CI -1·57, 0·70; P=0·45). Meta-regression analysis identified that probiotics had significant effects on reduction of glucose, HbA1c, insulin and HOMA-IR in participants with diabetes, but not in participants with other risk factors. The present meta-analysis suggested that probiotics may be used as an important dietary supplement in reducing the glucose metabolic factors associated with diabetes.

  2. Initiating therapy or switching to biphasic insulin aspart improves glycaemic control in type 2 diabetes: an Indian experience from the A1chieve study.

    Kumar, A; Sharma, S K; Rajput, R; Unnikrishnan, A G

    2013-01-01

    Biphasic insulin aspart 30 (BIAsp 30) has been used in patients for almost a decade; There is a wealth of knowledge from clinical trials to document its efficacy and safety and suggest that BIAsp 30 is an option for initiation and intensification of insulin therapy in patients with type 2 diabetes mellitus (T2DM). The A1chieve was a non-interventional study that explored the safety and effectiveness of initiating or switching to insulin analogues in routine clinical practice in more than 60,000 patients from 28 different countries. In this manuscript, we discuss the findings from the subgroup of the Indian cohort who were treated with BIAsp 30. In a cohort of 15287 who were on BIAsp 30, 12645 (83%) were insulin naive and 2642 (17%) had been on insulin therapy earlier. Glycaemic parameters were high at baseline. Mean (SD) HbA1c was 9.2% (1.3) in the these and was comparable in the insulin naive and insulin experienced groups. After 24 weeks of therapy with BIAsp 30, there were reductions in HbA1c in both the insulin naive group, [-1.8 (1.3)] and insulin experienced group [-1.6 (1.3)]. Fasting plasma glucose (FPG) and postprandial plasma glucose (PPG) levels were also reduced significantly from baseline [-3.4 (2.7) and -4.8 (3.8) mmol/L, respectively, p < 0.05). Overall, hypoglycaemia decreased from 1.33 events/patient years at baseline to 0.19 events/patient years at 24 weeks. There was also an increase in quality of life score as evaluated by EQ-5D questionnaire. Initiating insulin therapy with or switching to BIAsp 30 in patients with poor glycaemic control leads to an improvement in glycaemic profile with no major hypoglycaemia or clinically significant weight gain. Therapy with BIAsp 30 also improves the quality of life in patients with type 2 diabetes.

    2004-01-01

    @@ Insulin lispro is an insulin analogue that has the advantages of being fast-acting, convenient, and less likely to lead to hypoglycaemic episodes. Previous studies have proven its value in treating both Type 1 and Type 2 diabetes both alone and in combination with different treatment regimens.1,2 However, diabetes is heterogeneous and differs in etiology and clinical characteristics in different ethnic groups. Even with the same insulin treatment, different diets will produce different glycaemic profiles. Diet patterns differ between different ethnic groups. Traditional oriental foods are characterized by a higher proportion of carbohydrates and a lower proportion of fat compared to Caucasian diets. To date, there has been no study on the use of insulin lispro in Chinese diabetic patients. Whether the Chinese dietary pattern will affect the efficacy of insulin lispro treatment remains unknown. Therefore, we conducted this trial to assess the efficacy of insulin lispro treatment in Chinese patients.

    Background The debate over the overall benefits of self-monitoring of blood glucose in type 2 diabetes patients is still continuing.We aimed to assess the difference in glycaemic control and coronary heart disease (CHD) risk levels of experimental type 2 diabetes patients provided with facilities for self-monitoring blood glucose and their counterparts without such facilities.Methods Sixty-one patients who had no prior experience in using glucometers were studied as intervention (n=30) and control (n=31) groups.The intervention group was trained in self-monitoring of blood glucose and documentation.Baseline blood glucose and fasting blood glucose were measured and the intervention patients were provided with glucometers and advised to self-monitor their fasting and postprandial blood glucose over six months.The 10-year CHD risk levels were determined with the United Kingdom Prospective Diabetes Study-derived risk engine calculator.Results The age and diabetes duration were similar in the two groups (P >0.05).The majority of the patients were unemployed or retired females with only a primary level education.After 3 months,the haemogolbin A1c (HbA1c) levels of the control patients remained unchanged ((7.8±0.3)% vs.(7.9±0.4)%,P >0.05) whereas the HbA1c levels of the intervention patients were significantly reduced from the baseline at three ((9.6±0.3)% vs.(7.8±0.3)%,P <0.001) and six ((9.2±0.4)% vs.(7.5±0.3)%,P <0.001) months.Interestingly,while the 10-year CHD risk level of the control group remained unchanged after three months,that of the intervention group was remarkably reduced at three and six months from the baseline level ((7.4±1.3)% vs.(4.5±0.9)%,P=0.056).Conclusion Self-monitoring of blood glucose in type 2 diabetes patients significantly improved glycaemic control and the CHD risk profile,suggesting that type 2 diabetes patients will potentially benefit from inclusion of glucose meters and testing strips in their health-care package.

  6. Tight glycaemic control is a key factor in wound healing enhancement strategies in an experimental diabetes mellitus model.

    O'Sullivan, J B

    2012-02-01

    BACKGROUND: Diabetes mellitus is a leading cause of impaired wound healing. The aim of this study was to establish a glucose-controlled diabetic wound healing model. METHOD: Sprague-Dawley rats were divided into three groups: Control group (C), Diabetic Non-glucose Controlled group (DNC) and Diabetic glucose Controlled group (DC). RESULTS: Glucose control was achieved using Insulman Rapid (average daily glucose level <10 mmol\\/L). 18 Sprague-Dawley rats underwent a dorsal skin wound incision and 10 days later were killed. Fresh and fixed wound tensile strength, hydroxyproline and transforming growth factor beta-1 levels were improved in the DC group when compared to the DNC group. The quantity of fibroblasts present was similar in each group. CONCLUSION: This study demonstrates the impact that diabetes has on acute wound healing and suggests that wound modulating agents must be tested in both the tightly glucose-controlled as well as the poorly glucose-controlled diabetic animal models prior to proceeding with translational clinical studies.

  7. Metabolic effects of low glycaemic index diets

    2009-01-01

    Full Text Available Abstract The persistence of an epidemic of obesity and type 2 diabetes suggests that new nutritional strategies are needed if the epidemic is to be overcome. A promising nutritional approach suggested by this thematic review is metabolic effect of low glycaemic-index diet. The currently available scientific literature shows that low glycaemic-index diets acutely induce a number of favorable effects, such as a rapid weight loss, decrease of fasting glucose and insulin levels, reduction of circulating triglyceride levels and improvement of blood pressure. The long-term effect of the combination of these changes is at present not known. Based on associations between these metabolic parameters and risk of cardiovascular disease, further controlled studies on low-GI diet and metabolic disease are needed.

    Full Text Available Childhood obesity is associated with increased risk of adult obesity and metabolic disease. Diet and lifestyle in pregnancy influence fetal programming; however the influence of specific dietary components, including low glycaemic index (GI, remains complex. We examined the effect of a maternal low GI dietary intervention on offspring adiposity at 6 months and explored the association between diet and lifestyle factors in pregnancy and infant body composition at 6 months. 280 6-month old infant and mother pairs from the control (n = 142 and intervention group (n = 138, who received low GI dietary advice in pregnancy, in the ROLO study were analysed. Questionnaires (food diaries and lifestyle were completed during pregnancy, followed by maternal lifestyle and infant feeding questionnaires at 6 months postpartum. Maternal anthropometry was measured throughout pregnancy and at 6 months post-delivery, along with infant anthropometry. No difference was found in 6 months infant adiposity between control and intervention groups. Maternal trimester three GI, trimester two saturated fats and trimester one and three sodium intake were positively associated with offspring adiposity, while trimester two and three vitamin C intake was negatively associated. In conclusion associations were observed between maternal dietary intake and GI during pregnancy and offspring adiposity at 6 months of age.

    2016-01-01

    This randomized, double‐blind, placebo‐controlled, crossover study was the first to determine the effects of luseogliflozin in combination with a low‐carbohydrate diet (LCD) on 24‐h glucose variability, assessed by continuous glucose monitoring (CGM). A total of 18 Japanese patients with type 2 diabetes were randomized into two groups, in which patients first received luseogliflozin 2.5 mg once daily then placebo for 8 days each, or vice versa. Patients took luseogliflozin or placebo with a normal‐carbohydrate diet (NCD) on day 7 and with the LCD on day 8. CGM was performed on both days. Luseogliflozin significantly reduced glucose exposure in terms of the area under the curve over the course of 24 h when administered with the NCD (difference vs placebo: −555.6 mg/dl·h [1 mg/dl = 0.0556 mmol/l]; p diet. Although glucose levels were lower with the LCD than with the NCD in the placebo treatment period, luseogliflozin with the LCD improved glycaemic control throughout the day to nearly the same extent as luseogliflozin with the NCD, without inducing hypoglycaemia.

  10. Weight gain is associated with improved glycaemic control but with adverse changes in plasma lipids and blood pressure isn Type 1 diabetes.

    Ferriss, J B

    2012-02-03

    AIMS: To assess the effects of weight gain on metabolic control, plasma lipids and blood pressure in patients with Type 1 diabetes. METHODS: Patients in the EURODIAB Prospective Complications Study (n = 3250) were examined at baseline and 1800 (55%) were re-examined a mean of 7.3 years later. Patients had Type 1 diabetes, defined as a diagnosis made before age 36 years and with a need for continuous insulin therapy within a year of diagnosis. Patients were aged 15-60 years at baseline and were stratified for age, sex and duration of diabetes. RESULTS: The change in HbA(1c) from baseline to follow-up examination was significantly more favourable in those who gained 5 kg or more during follow-up (\\'marked weight gain\\') than in patients who gained less or no weight or lost weight (\\'less or no weight gain\\'). In those with marked weight gain, there was a significantly greater rise in plasma triglycerides and total cholesterol and significantly less favourable changes in low-density lipoprotein and high-density lipoprotein cholesterol compared with those with less or no weight gain, with or without adjustment for HbA(1c). Systolic and diastolic blood pressure also rose significantly more in the group with marked weight gain. CONCLUSION: Weight gain in patients with Type 1 diabetes has adverse effects on plasma lipids and blood pressure, despite a small improvement in glycaemic control.

  13. The cross-sectional associations between sense of coherence and diabetic microvascular complications, glycaemic control, and patients' conceptions of type 1 diabetes

    Saraheimo Markku

    2010-11-01

    Full Text Available Abstract Background Sense of coherence (SOC has been associated with various self-care behaviours in the general population. As the management of type 1 diabetes heavily relies on self-management, the SOC concept could also prove important in this population. This paper is a report of a study conducted among patients with type 1 diabetes to assess the associations between SOC and glycaemic control, microvascular complications, and patients' conceptions of their disease. Methods Altogether 1,264 adult patients (45% men, age range 18-82 years with type 1 diabetes participated in this cross-sectional study. SOC was evaluated using a 13-item SOC questionnaire. Standardized assays were used to determine HbA1c. Nephropathy status was based on albumin excretion rate and retinal laser-treatment was used as an indication of severe retinopathy. Patients' subjective conceptions of diabetes were studied using a questionnaire. Results Higher SOC scores, reflecting stronger SOC, were associated with lower HbA1c values. Strong SOC was independently associated with reaching the HbA1c level 1c, weak SOC was associated with the presence of nephropathy among men, but not women. No associations were observed between SOC and severe retinopathy. Four dimensions describing patients' conceptions of HbA1c, complications, diabetes control and hypoglycaemia were formed from the diabetes questionnaire. Weak SOC was independently associated with worse subjective conceptions in the dimensions of HbA1c and hypoglycaemia. Furthermore among men, an association between weak SOC and the complications factor was observed. Conclusion Interventions to improve patients' SOC, if available, could improve patients' metabolic control and therefore also reduce the incidence of diabetic complications.

  14. Comparative evaluation of glipizide and fenugreek (Trigonella foenum-graecum seeds as monotherapy and combination therapy on glycaemic control and lipid profile in patients with type 2 diabetes mellitus

    2016-06-01

    Conclusions: Monotherapy with fenugreek produced significant improvement in glycaemic control and dyslipidaemia. Glipizide monotherapy was more efficacious in controlling FBG and HbA1c levels than fenugreek monotherapy or in combination with fenugreek; glipizide monotherapy had no effect on lipid profile whereas fenugreek monotherapy was more efficacious in controlling dyslipidaemia than in combination with glipizide. Both drugs as monotherapy or in combination were well-tolerated by the patients. [Int J Basic Clin Pharmacol 2016; 5(3.000: 942-950

  15. Improving glycaemic control and life skills in adolescents with type 1 diabetes: A randomised, controlled intervention study using the Guided Self-Determination-Young method in triads of adolescents, parents and health care providers integrated into routine paediatric outpatient clinics

    Esbensen Bente

    2011-06-01

    Full Text Available Abstract Background Adolescents with type 1 diabetes face demanding challenges due to conflicting priorities between psychosocial needs and diabetes management. This conflict often results in poor glycaemic control and discord between adolescents and parents. Adolescent-parent conflicts are thus a barrier for health care providers (HCPs to overcome in their attempts to involve both adolescents and parents in improvement of glycaemic control. Evidence-based interventions that involve all three parties (i.e., adolescents, parents and HCPs and are integrated into routine outpatient clinic visits are lacking. The Guided Self-Determination method is proven effective in adult care and has been adapted to adolescents and parents (Guided Self-Determination-Young (GSD-Y for use in paediatric diabetes outpatient clinics. Our objective is to test whether GSD-Y used in routine paediatric outpatient clinic visits will reduce haemoglobin A1c (HbA1c concentrations and improve adolescents' life skills compared with a control group. Methods/Design Using a mixed methods design comprising a randomised controlled trial and a nested qualitative evaluation, we will recruit 68 adolescents age 13 - 18 years with type 1 diabetes (HbA1c > 8.0% and their parents from 2 Danish hospitals and randomise into GSD-Y or control groups. During an 8-12 month period, the GSD-Y group will complete 8 outpatient GSD-Y visits, and the control group will completes an equal number of standard visits. The primary outcome is HbA1c. Secondary outcomes include the following: number of self-monitored blood glucose values and levels of autonomous motivation, involvement and autonomy support from parents, autonomy support from HCPs, perceived competence in managing diabetes, well-being, and diabetes-related problems. Primary and secondary outcomes will be evaluated within and between groups by comparing data from baseline, after completion of the visits, and again after a 6-month follow-up. To

    2013-03-01

    Bread has become a widely consumed staple food in South-east Asia. However, there is very little data on the glycaemic potential of local commercial breads. The objective of this study was to comparatively assess the glycaemic potential of some commonly consumed commercial breads using a validated in vitro model. Sixteen types of breads representing the most popular brands and types were evaluated. The results showed that white and enriched white breads had a greater glycaemic potential than wholemeal breads (rapidly digestible starch (RDS) content >450 mg of glucose/g of sample). The lowest glycaemic potential was observed for wholegrain breads (RDS content breads such as pandan bread, milk bread and corn loaf was also examined. Whist the data show that South-east Asian breads have notably differential effects on glycaemia, it highlights the need to formulate Asian dietary guidelines for bread which will enable better food choice and glycaemic control.

    2016-01-01

    Childhood obesity is associated with increased risk of adult obesity and metabolic disease. Diet and lifestyle in pregnancy influence fetal programming; however the influence of specific dietary components, including low glycaemic index (GI), remains complex. We examined the effect of a maternal low GI dietary intervention on offspring adiposity at 6 months and explored the association between diet and lifestyle factors in pregnancy and infant body composition at 6 months. 280 6-month old inf...

    2006-08-01

    The objective of this study was to compare glycemic control and insulin dosage in children with type 1 diabetes treated by a modified intensified insulin therapy MII using insulin pens (and premixed and regular insulin) with those on conventional insulin therapy. This was a longitudinal, randomized controlled trial for 6 months or more. From a cohort of 125 children with previously diagnosed type-1 diabetes (more than a year after diagnosis) two groups were randomly selected Group AI (n=20) and Group B (n=20). Group AI children and 10 children with recently diagnosed type 1 diabetes (Group AII) were allocated to MII using regular insulin and premixed insulin (30/70 and 40/60 and 50/50). Group B patients continued their conventional insulin therapy for the whole period of the trial. The main outcome measures were glycemic control measured by mean blood glucose concentration and percentage of glycated haemoglobin and total daily insulin dose. Mean blood glucose concentrations before the three main meals, and at midnight, (148, 147, 179 and 127 mg/dl, respectively) were lower in children receiving intensified MII compared with those receiving conventional insulin therapy (192, 174, 194 and 179 mg/dl, respectively) (standardized mean difference 34+/-15 mg/dl), equivalent to a difference of 1.9+/-0.8 mmol/l. This improved control during MII was achieved with no change in the average daily insulin dose in group-AI. In group-AII insulin dose decreased significantly during their first 6 moths of treatment (honeymooning). Glycemic control is better during MII using insulin pens and premixed and regular insulin compared with conventional insulin therapy, without any significant change in insulin dose needed to achieve this level of control. The difference in glycemic control between the two methods is significant and could reduce the risk of micro-vascular complications.

  4. A randomised control trial of low glycaemic index carbohydrate diet versus no dietary intervention in the prevention of recurrence of macrosomia.

    Walsh, Jennifer

    2010-01-01

    Maternal weight and maternal weight gain during pregnancy exert a significant influence on infant birth weight and the incidence of macrosomia. Fetal macrosomia is associated with an increase in both adverse obstetric and neonatal outcome, and also confers a future risk of childhood obesity. Studies have shown that a low glycaemic diet is associated with lower birth weights, however these studies have been small and not randomised 12. Fetal macrosomia recurs in a second pregnancy in one third of women, and maternal weight influences this recurrence risk 3.

  5. Effects of low glycaemic index/low glycaemic load vs. high glycaemic index/ high glycaemic load diets on overweight/obesity and associated risk factors in children and adolescents: a systematic review and meta-analysis.

    Schwingshackl, Lukas; Hobl, Lisa Patricia; Hoffmann, Georg

    2015-08-25

    The objective of the present systematic review and meta-analysis was to synthesize the available literature data investigating the effects of low glycaemic index/low glycamic load dietary regimens on anthropometric parameters, blood lipid profiles, and indicators of glucose metabolism in children and adolescents. Literature search was performed using the electronic databases MEDLINE, EMBASE, and the Cochrane Central Register of trials with restrictions to randomized controlled trials, but no limitations concerning language and publication date. Parameters taken into account were: body weight, body mass index, z-score of body mass index, fat mass, fat-free mass, height, waist cicrumference, hip circumference, waist-to-hip ratio, total cholesterol, LDL-cholesterol, HDL-cholesterol, triglycerides, diastolic and systolic blood pressure, fasting serum glucose, fasting serum insulin, HOMA-index, glycosylated haemoglobin, and C-reactive protein. Meta-analyses were performed for each parameter to assess pooled effect in terms of weighted mean differences between the post-intervention (or differences in means) of the low glycaemic index diets and the respective high glycaemic index counterparts. Data analysis was performed using the Review Manager 5.3. software. Nine studies enrolling 1.065 children or adolescents met the inclusion criteria. Compared to diets providing a high gylcaemic index, low glycaemic index protocols resulted in significantly more pronounced decreases in serum triglycerides [mean differences -15.14 mg/dl, 95%-CI (-26.26, -4.00)] and HOMA-index [mean difference -0.70, 95%-CI (-1.37, -0.04), fixed-effects model only]. Other parameters under investigation were not affected by either low or high glycaemic indices. The present systematic review and meta-analysis provides evidence of a beneficial effect of a low glycaemic index/load diet in children and adolescents being either overweight or obese. Regarding the limitations of this analysis, further studies

    2005-06-01

    Full Text Available Abstract Background We do not yet know how to use blood glucose self-monitoring (BGSM most effectively in the self-management of type 2 diabetes treated with oral medication. Training in monitoring may be most effective in improving glycaemic control and well being when results are linked to behavioural change. Methods/design DiGEM is a three arm randomised parallel group trial set in UK general practices. A total of 450 patients with type 2 diabetes managed with lifestyle or oral glucose lowering medication are included. The trial compares effectiveness of three strategies for monitoring glycaemic control over 12 months (1 a control group with three monthly HbA1c measurements; interpreted with nurse-practitioner; (2 A self-testing of blood glucose group; interpreted with nurse- practitioner to inform adjustment of medication in addition to 1; (3 A self-monitoring of blood glucose group with personal use of results to interpret results in relation to lifestyle changes in addition to 1 and 2. The trial has an 80% power at a 5% level of significance to detect a difference in change in the primary outcome, HbA1c of 0.5% between groups, allowing for an attrition rate of 10%. Secondary outcome measures include health service costs, well-being, and the intervention effect in sub-groups defined by duration of diabetes, current management, health status at baseline and co-morbidity. A mediation analysis will explore the extent to which changes in beliefs about self-management of diabetes between experimental groups leads to changes in outcomes in accordance with the Common Sense Model of illness. The study is open and has recruited more than half the target sample. The trial is expected to report in 2007. Discussion The DiGEM intervention and trial design address weaknesses of previous research by use of a sample size with power to detect a clinically significant change in HbA1c, recruitment from a well-characterised primary care population, definition

    The objective of the present study was to determine the glycaemic index (GI) and glycaemic load (GL) values of standard portion sizes of Southeast Asian traditional foods. A total of fifteen popular Southeast Asian foods were evaluated. Of these foods, three were soft drinks, while the other twelve were solid foods commonly consumed in this region. In total, forty-seven healthy participants (eighteen males and twenty-nine females) volunteered to consume either glucose at least twice or one of the fifteen test foods after a 10-12 h overnight fast. Blood glucose concentrations were analysed before consumption of the test food, and 15, 30, 45, 60, 90 and 120 min after food consumption, using capillary blood samples. The GI value of each test food was calculated by expressing the incremental area under the blood glucose response curve (IAUC) value of the test food as a percentage of each participant's average IAUC value, with glucose as the reference food. Among the fifteen foods tested, six belonged to low-GI foods (Ice Green Tea, Beehoon, Pandan Waffle, Curry Puff, Youtiao and Kaya Butter Toast), three belonged to medium-GI foods (Barley Drink, Char Siew Pau and Nasi Lemak), and the other six belonged to high-GI foods (Ice Lemon Tea, Chinese Carrot Cake, Chinese Yam Cake, Chee Cheong Fun, Lo Mai Gai and Pink Rice Cake). The GI and GL values of these traditional foods provide valuable information to consumers, researchers and dietitians on the optimal food choice for glycaemic control. Moreover, our dataset provides GI values of fifteen foods that were not previously tested extensively, and it presents values of foods commonly consumed in Southeast Asia.

    Full Text Available Objective: This paper compared the effects of the sibutramine and of the metformin in the patients' obesity bearers insulin resistance. Methods: They were appraised 16 subjects obese with IMC above 30 Kg/m2, during 6 months and divided in two groups. The patients, before they begin the study, they were submitted to an evaluation anthropometric, clinic and laboratorial. All the patients received an individualized alimentary plan, respecting the total energy expense daily. Results: At the end of the study, it was observed that the plasmatic concentrations of insulin suffered reduction of 12,1% (sibutramine and 20,7% (metformin, and the values of HOMA also suffered reduction of 11,2% and 23,5%, respectively in the group sibutramine and metformin. In compensation, the patients of the group sibutramine obtained more satisfactory results than the group metformin in the reduction of the corporal weight and in IMC.Conclusion: This study demonstrated that the sibutramine, when compared to the metformin, it presents good results in the patients' glycaemic control, mainly in the insulin values and HOMA. The sibutramine, when prescribed in a rational way, an important therapeutic tool can be considered in the control of the diabetes type 2 and others adjunct pathology, however it should always be used simultaneous with an agent antidiabetic in those patient ones.

    Epidemiological evidence regarding the association between carbohydrate intake, glycaemic load (GL) and glycaemic index (GI) and risk of ovarian cancer has been mixed. Little is known about their impact on ovarian cancer risk in African-American women. Associations between carbohydrate quantity and quality and ovarian cancer risk were investigated among 406 cases and 609 controls using data from the African American Cancer Epidemiology Study (AACES). AACES is an ongoing population-based case-control study of ovarian cancer in African-Americans in the USA. Cases were identified through rapid case ascertainment and age- and site-matched controls were identified by random-digit dialling. Dietary information over the year preceding diagnosis or the reference date was obtained using a FFQ. Multivariable logistic regression models were used to estimate odds ratios and 95% CI adjusted for covariates. The OR comparing the highest quartile of total carbohydrate intake and total sugar intake v. the lowest quartile were 1·57 (95% CI 1·08, 2·28; P trend=0·03) and 1·61 (95% CI 1·12, 2·30; P trendcancer (OR 1·18 for each 10 units/4184 kJ (1000 kcal); 95% CI 1·04, 1·33). No associations were observed for starch or GI. Our findings suggest that high intake of total sugars and GL are associated with greater risk of ovarian cancer in African-American women.

    2010-01-01

    Full Text Available Background. Carbohydrates have varied rates of digestion and absorption that induces different hormonal and metabolic responses in the body. Given the abundance of carbohydrate sources in the Philippines, the determination of the glycaemic index (GI of local foods may prove beneficial in promoting health and decreasing the risk of diabetes in the country. Methods. The GI of Quality Protein Maize (QPM grits, milled rice, and the mixture of these two food items were determined in ten female subjects. Using a randomized crossover design, the control bread and three test foods were given on separate occasions after an overnight fast. Blood samples were collected through finger prick at time intervals of 0, 15, 30, 45, 60, 90, and 120 min and analyzed for glucose concentrations. Results. The computed incremental area under the glucose response curve (IAUC varies significantly across test foods (P<.0379 with the pure QPM grits yielding the lowest IAUC relative to the control by 46.38. Resulting GI values of the test foods (bootstrapped were 80.36 (SEM 14.24, 119.78 (SEM 18.81, and 93.17 (SEM 27.27 for pure QPM grits, milled rice, and rice-QPM grits mixture, respectively. Conclusion. Pure QPM corn grits has a lower glycaemic response compared to milled rice and the rice-corn grits mixture, which may be related in part to differences in their dietary fibre composition and physicochemical characteristics. Pure QPM corn grits may be a more health beneficial food for diabetic and hyperlipidemic individuals.

  11. Maximal entanglement achievable by controlled dynamics

    Serafini, Alessio

    2009-01-01

    We consider the feedback control of quantum systems comprised of any number of bosonic degrees of freedom. We derive a general upper bound for the logarithmic negativity achievable, at steady state, with continuous Gaussian measurements on the environment and linear driving on the system. Our results apply to rotating wave system-bath couplings and to any quadratic system's Hamiltonian. Furthermore, we apply this upper bound to parametric processes, show it to be tight, and compare it to feedback strategies limited to local measurements.

  12. Can bread processing conditions alter glycaemic response?

    Lau, Evelyn; Soong, Yean Yean; Zhou, Weibiao; Henry, Jeyakumar

    2015-04-15

    Bread is a staple food that is traditionally made from wheat flour. This study aimed to compare the starch digestibility of western baked bread and oriental steamed bread. Four types of bread were prepared: western baked bread (WBB) and oriental steamed bread (OSB), modified baked bread (MBB) made with the OSB recipe and WBB processing, and modified steamed bread (MSB) made with the WBB recipe and OSB processing. MBB showed the highest starch digestibility in vitro, followed by WBB, OSB and MSB. A similar trend was observed for glycaemic response in vivo. MBB, WBB, OSB and MSB had a glycaemic index of 75±4, 71±5, 68±5 and 65±4, respectively. Processing differences had a more pronounced effect on starch digestibility in bread, and steamed bread was healthier in terms of glycaemic response. The manipulation of processing conditions could be an innovative route to alter the glycaemic response of carbohydrate-rich foods.

  14. A Cross-Sectional Study Demonstrating Increased Serum Amyloid A Related Inflammation in High-Density Lipoproteins from Subjects with Type 1 Diabetes Mellitus and How This Association Was Augmented by Poor Glycaemic Control

    Jane McEneny

    2015-01-01

    Full Text Available Inflammatory atherosclerosis is increased in subjects with type 1 diabetes mellitus (T1DM. Normally high-density lipoproteins (HDL protect against atherosclerosis; however, in the presence of serum amyloid-A- (SAA- related inflammation this property may be reduced. Fasting blood was obtained from fifty subjects with T1DM, together with fifty age, gender and BMI matched control subjects. HDL was subfractionated into HDL2 and HDL3 by rapid ultracentrifugation. Serum-hsCRP and serum-, HDL2-, and HDL3-SAA were measured by ELISAs. Compared to control subjects, SAA was increased in T1DM subjects, nonsignificantly in serum (P=0.088, and significantly in HDL2(P=0.003 and HDL3(P=0.005. When the T1DM group were separated according to mean HbA1c (8.34%, serum-SAA and HDL3-SAA levels were higher in the T1DM subjects with HbA1c ≥ 8.34%, compared to when HbA1c was 0.05. This cross-sectional study demonstrated increased SAA-related inflammation in subjects with T1DM that was augmented by poor glycaemic control. We suggest that SAA is a useful inflammatory biomarker in T1DM, which may contribute to their increased atherosclerosis risk.

  15. Is self-monitoring of blood glucose effective in improving glycaemic control in type 2 diabetes without insulin treatment: a meta-analysis of randomised controlled trials

    Zhu, Hongmei; Zhu, Yanan; Leung, Siu-wai

    2016-01-01

    Objective The present study aimed to verify the effectiveness of self-monitoring of blood glucose (SMBG) in patients with non-insulin-treated type 2 diabetes (T2D). Methods A comprehensive literature search was conducted in PubMed, Cochrane Library, Web of Science, ScienceDirect and ClinicalTrials.gov from their respective inception dates to 26 October 2015. Eligible randomised controlled trials (RCTs) were included according to prespecified criteria. The quality of the included RCTs was evaluated according to the Cochrane risk of bias tool, and the evidence quality of meta-analyses was assessed by the Grading of Recommendation, Assessment, Development, and Evaluation (GRADE) criteria. A meta-analysis of primary and secondary outcome measures was performed. Sensitivity and subgroup analyses were carried out to evaluate the robustness and heterogeneity of the findings. Begg's and Egger's tests were used to quantify publication biases. Results A total of 15 RCTs, comprising 3383 patients with non-insulin-treated T2D, met the inclusion criteria. The SMBG intervention improved glycated haemoglobin (HbA1c) (mean difference −0.33; 95% CI −0.45 to −0.22; p=3.0730e−8; n=18), body mass index (BMI; −0.65; −1.18 to −0.12; p=0.0164; n=9) and total cholesterol (TC; −0.12; −0.20 to −0.04; p=0.0034; n=8) more effectively than the control in overall effect. The sensitivity analysis revealed little difference in overall effect, indicating the robustness of the results. SMBG moderated HbA1c levels better than the control in all subgroup analyses. Most of the RCTs had high risk of bias in blinding, while the overall quality of evidence for HbA1c was moderate according to the GRADE criteria. Publication bias was moderate for BMI. Conclusions SMBG improved HbA1c levels in the short term (≤6-month follow-up) and long term (≥12-month follow-up) in patients with T2D who were not using insulin.

  16. Estimates of Savings Achievable from Irrigation Controller

    Williams, Alison; Fuchs, Heidi; Whitehead, Camilla Dunham

    2014-03-28

    This paper performs a literature review and meta-analysis of water savings from several types of advanced irrigation controllers: rain sensors (RS), weather-based irrigation controllers (WBIC), and soil moisture sensors (SMS).The purpose of this work is to derive average water savings per controller type, based to the extent possible on all available data. After a preliminary data scrubbing, we utilized a series of analytical filters to develop our best estimate of average savings. We applied filters to remove data that might bias the sample such as data self-reported by manufacturers, data resulting from studies focusing on high-water users, or data presented in a non-comparable format such as based on total household water use instead of outdoor water use. Because the resulting number of studies was too small to be statistically significant when broken down by controller type, this paper represents a survey and synthesis of available data rather than a definitive statement regarding whether the estimated water savings are representative.

  17. Food Intake and Dietary Glycaemic Index in Free-Living Adults with and without Type 2 Diabetes Mellitus

    Alexandra M. Johnstone

    2011-06-01

    Full Text Available A recent Cochrane review concluded that low glycaemic index (GI diets are beneficial in glycaemic control for patients with type 2 diabetes mellitus (T2DM. There are limited UK data regarding the dietary GI in free-living adults with and without T2DM. We measured the energy and macronutrient intake and the dietary GI in a group (n = 19 of individuals with diet controlled T2DM and a group (n = 19 without diabetes, matched for age, BMI and gender. Subjects completed a three-day weighed dietary record. Patients with T2DM consumed more daily portions of wholegrains (2.3 vs. 1.1, P = 0.003, more dietary fibre (32.1 vs. 20.9 g, P < 0.001 and had a lower diet GI (53.5 vs. 57.7, P = 0.009 than subjects without T2DM. Both groups had elevated fat and salt intake and low fruit and vegetable intake, relative to current UK recommendations. Conclusions: Patients with T2DM may already consume a lower GI diet than the general population but further efforts are needed to reduce dietary GI and achieve other nutrient targets.

    2009-11-01

    Full Text Available Abstract Background Corn silk contains proteins, vitamins, carbohydrates, Ca, K, Mg and Na salts, fixed and volatile oils, steroids such as sitosterol and stigmasterol, alkaloids, saponins, tannins, and flavonoids. Base on folk remedies, corn silk has been used as an oral antidiabetic agent in China for decades. However, the hypoglycemic activity of it has not yet been understood in terms of modern pharmacological concepts. The purpose of this study is to investigate the effects of corn silk on glycaemic metabolism. Methods Alloxan and adrenalin induced hyperglycemic mice were used in the study. The effects of corn silk on blood glucose, glycohemoglobin (HbA1c, insulin secretion, damaged pancreatic β-cells, hepatic glycogen and gluconeogenesis in hyperglycemic mice were studied respectively. Results After the mice were orally administered with corn silk extract, the blood glucose and the HbA1c were significantly decreased in alloxan-induced hyperglycemic mice (p 0.05. Although corn silk extract increased the level of hepatic glycogen in the alloxan-induced hyperglycemic mice, there was no significant difference between them and that of the control group(p > 0.05. Conclusion Corn silk extract markedly reduced hyperglycemia in alloxan-induced diabetic mice. The action of corn silk extract on glycaemic metabolism is not via increasing glycogen and inhibiting gluconeogenesis but through increasing insulin level as well as recovering the injured β-cells. The results suggest that corn silk extract may be used as a hypoglycemic food or medicine for hyperglycemic people in terms of this modern pharmacological study.

  7. Achieving Control of Lesion Growth in CNS with Minimal Damage

    Raja, Mathankumar

    2012-01-01

    Lesions in central nervous system (CNS) and their growth leads to debilitating diseases like Multiple Sclerosis (MS), Alzheimer's etc. We developed a model earlier which shows how the lesion growth can be arrested through a beneficial auto-immune mechanism. The success of the approach depends on a set of control parameters and their phase space was shown to have a smooth manifold separating the uncontrolled lesion growth region from the controlled. Here we show that an optimal set of parameter values exist which minimizes system damage while achieving control of lesion growth.

  8. Co-ingestion of essence of chicken to moderate glycaemic response of bread.

    Sun, Lijuan; Wei Jie Tan, Kevin; Jeyakumar Henry, Christiani

    2015-01-01

    Essence of chicken (EOC) beverage is a chicken meat extract, widely consumed in Asian countries for health benefits. EOC is a rich source of peptides and amino acids. White bread has become a popular staple food in all regions of Southeast Asia. A randomized controlled, crossover, non-blind trial was performed to investigate the role of EOC on glycaemic response (GR) of white bread. Ten healthy young subjects returned on five separate days for three glucose and two bread sessions. Subjects consumed bread or bread with EOC. The 120 min incremental area under the curve was significantly lower after consuming two bottles of EOC with bread than white bread alone. The glycaemic index (GI) of white bread was 83 and white bread with EOC 57. The co-ingestion of EOC may be a practical and simple way to reduce the GR of bread and other starch-based staples.

    2016-11-01

    Nutrition transition to high energy-dense foods has been implicated as the major causes of diet related diseases. Plantain-based dough meals supplemented with soybean cake and cassava fibre were developed by combining them in different proportions using response surface methodology. The flour blends were analyzed for the nutritional composition while the glycaemic index, antidiabetic potentials and protein digestibility of the dough meals were determined in wistar rats. The nutritional and essential amino acid contents of the flour blends were comparable to that of cerolina (a commercially available food product commonly recommended for diabetic patients). The rats fed with the formulated dough meals had lower glycaemic index and glycaemic load, and the blood glucose was significantly reduced compared to cerolina and metformin (a synthetic antidiabetic drug). All the plantain-based dough meals were comparable to cerolina and metformin in terms of nutritional quality and blood glycaemic control activities, respectively. Hence, the formulated plantain-based dough meals have potential to be used for the prevention and management of diabetes mellitus.

  19. Contributors to dietary glycaemic index and glycaemic load in the Netherlands: the role of beer.

    Sluik, Diewertje; Atkinson, Fiona S; Brand-Miller, Jennie C; Fogelholm, Mikael; Raben, Anne; Feskens, Edith J M

    2016-04-14

    Diets high in glycaemic index (GI) and glycaemic load (GL) have been associated with a higher diabetes risk. Beer explained a large proportion of variation in GI in a Finnish and an American study. However, few beers have been tested according to International Organization for Standardization (ISO) methodology. We tested the GI of beer and estimated its contribution to dietary GI and GL in the Netherlands. GI testing of pilsner beer (Pilsner Urquell) was conducted at The University of Sydney according to ISO international standards with glucose as the reference food. Subsequently, GI and GL values were assigned to 2556 food items in the 2011 Dutch food composition table using a six-step methodology and consulting four databases. This table was linked to dietary data from 2106 adults in the Dutch National Food Consumption Survey 2007-2010. Stepwise linear regression identified contribution to inter-individual variation in dietary GI and GL. The GI of pilsner beer was 89 (SD 5). Beer consumption contributed to 9·6 and 5·3% inter-individual variation in GI and GL, respectively. Other foods that contributed to the inter-individual variation in GI and GL included potatoes, bread, soft drinks, sugar, candy, wine, coffee and tea. The results were more pronounced in men than in women. In conclusion, beer is a high-GI food. Despite its relatively low carbohydrate content (approximately 4-5 g/100 ml), it still made a contribution to dietary GL, especially in men. Next to potatoes, bread, sugar and sugar-sweetened beverages, beer captured a considerable proportion of between-person variability in GI and GL in the Dutch diet.

  20. Health potential of polyols as sugar replacers, with emphasis on low glycaemic properties.

    Livesey, Geoffrey

    2003-12-01

    reduced using polyols. Improved glycated haemoglobin as a marker of glycaemic control was found in a 12-week study of type 2 diabetes mellitus patients consuming polyol, adding to other studies showing improved glucose control on ingestion of low-GI carbohydrate. In general some improvement in long-term glycaemic control was discernible on reducing the glycaemic load via GI by as little as 15-20 g daily. Similar amounts of polyols are normally acceptable. Although polyols are not essential nutrients, they contribute to clinically recognised maintenance of a healthy colonic environment and function. A role for polyols and polyol foods to hydrate the colonic contents and aid laxation is now recognised by physicians. Polyols favour saccharolytic anaerobes and aciduric organisms in the colon, purifying the colon of endotoxic, putrefying and pathological organisms, which has clinical relevance. Polyols also contribute towards short-chain organic acid formation for a healthy colonic epithelium. Polyol tooth-friendliness and reduced energy values are affirmed and add to the potential benefits. In regard to gastrointestinal tolerance, food scientists and nutritionists, physicians, and dentists have in their independent professional capacities each now described sensible approaches to the use and consumption of polyols.

  3. Controlling open quantum systems: tools, achievements, and limitations

    Koch, Christiane P.

    2016-06-01

    The advent of quantum devices, which exploit the two essential elements of quantum physics, coherence and entanglement, has sparked renewed interest in the control of open quantum systems. Successful implementations face the challenge of preserving relevant nonclassical features at the level of device operation. A major obstacle is decoherence, which is caused by interaction with the environment. Optimal control theory is a tool that can be used to identify control strategies in the presence of decoherence. Here we review recent advances in optimal control methodology that allow typical tasks in device operation for open quantum systems to be tackled and discuss examples of relaxation-optimized dynamics. Optimal control theory is also a useful tool to exploit the environment for control. We discuss examples and point out possible future extensions.

    Shehadeh, N; Maor, Y

    2015-11-01

    We performed a non-inferiority trial comparing insulin detemir (Levemir) and biphasic insulin (NovoMix70) to standard care during Ramadan fast in insulin treated type 2 diabetes mellitus (T2DM) patients. This was an open label, controlled, multicentre, cluster randomised non-inferiority study. Insulin treated T2DM patients from 12 randomly selected primary clinics received Levemir and NovoMix 70 (intervention, n = 127) or standard care according to the American Diabetes Association recommendations (control, n = 118). Insulin dose (intervention) was 60% of the usual, of this 40% was dosed as Levemir at sunrise and 60% as NovoMix 70 before dinner. Insulin was titrated according to daily 4 point self-measured blood glucose (4P-SMBG) levels. The primary outcome was the difference in mean daily 4P-SMBG during days 23-30 of treatment. Mean age was 60.1 (SD 8.9) and 59.4 (SD 10.1) years in the intervention and control respectively. Mean HbA1c was 8.38% (68 mmol/mol) (SD 0.96) and 8.45% (69 mmol/mol) (SD 1.08). Mean BMI was 32.99 (SD 7.05) and 33.08 (SD 7.24), respectively. The intervention was non-inferior to standard care as assessed by mean 4P-SMBG during days 23-30 of treatment [155 (SD 30.76) mg% and 159 (SD 33.24) mg% respectively, p = 0.269]. Adverse event rate was significantly lower in the intervention group [0.04 (SD 0.06) vs. 0.07 (SD 0.11), p = 0.010]. In particular, hypoglycaemia event rate was lower in the intervention group [0.00 (SD 0.01) vs. 0.01 (SD 0.03), p ≤ 0.001]. To conclude, treatment with Levemir and NovoMix 70 was non-inferior to standard care in this heterogeneous group of patients and was associated with less adverse events.

    Health authorities currently have high expectations for telemedicine (TM), as it addresses several major challenges: to improve access to healthcare (especially for patients in underserved or remote areas); to overcome the scarcity of specialists faced with epidemic disease; and to reduce the costs of healthcare while improving quality. The aims of TM in the field of diabetes differ according to the type of diabetes. In type 1 diabetes (T1DM) associated with complex insulin regimens, the goal of TM is to help patients achieve better control of their blood glucose levels through accurate adjustment of insulin doses. In type 2 diabetes (T2DM), while therapeutic adjustments may be necessary, improvement in blood glucose control is based primarily on behavioural changes (reduced calorie and carbohydrate intakes, increased physical activity). Many TM studies focusing on management of blood glucose levels have been published, but most failed to demonstrate any superiority of TM vs traditional care. While previously published meta-analyses have shown a slight advantage at best for TM, these meta-analyses included a mix of studies of varying durations and different populations (both T1DM and T2DM patients, adults and children), and tested systems of inconsistent quality. Studies published to date on TM suggest two currently promising approaches. First, handheld communicating devices, such as smartphones, loaded with software to apply physicians' prescriptions, have been shown to improve glycaemic control. These systems provide immediate assistance to the patient (such as insulin-dose calculation and food choice optimization at meals), and all data stored in the smartphone can be transmitted to authorized caregivers, enabling remote monitoring and even teleconsultation. These systems, initially developed for T1DM, appear to offer many possibilities for T2DM, too. Second, systems combining an interactive Internet system (or a mobile phone coupled to a remote server) with a

  8. Glycaemic response to barley porridge varying in dietary fibre content.

    Thondre, Pariyarath S; Wang, Ke; Rosenthal, Andrew J; Henry, Christiani J K

    2012-03-01

    The interest in barley as a food is increasing worldwide because of its high dietary fibre (DF) content and low glycaemic index (GI). DF in cereals may prove beneficial in improving blood glucose response in the long term. However, a dose-dependent effect of insoluble fibre on reducing postprandial blood glucose levels is yet to be proven. The objective of the present study was to determine the glycaemic response to two barley porridges prepared from whole barley grains varying in fibre content. In two separate non-blind randomised crossover trials, ten human subjects consumed barley porridge with 16 g/100 g and 10 g/100 g fibre content provided in different serving sizes (equivalent to 25 and 50 g available carbohydrate). The glycaemic response to both barley porridges was significantly lower than the reference glucose (P porridges. We concluded that irrespective of the difference in total fibre content or serving size of barley porridges, their GI values did not differ significantly.

    Also note that structured abstracts are not allowed per journal style: What is the effect of a mouthwash containing various active chemical ingredients on plaque control and managing gingivitis in adults based on evidence gathered from existing systematic reviews? The summarized evidence suggests that mouthwashes containing chlorhexidine(CHX) and essential oils (EO) had a large effect supported by a strong body of evidence. Also there was strong evidence for a moderate effect of cetylpyridinium chloride(CPC). Evidence suggests that a CHX mouthwash is the first choice, the most reliable alternative is EO. No difference between CHX and EO with respect to gingivitis was observed.

CONCLUSIONS: Our findings do not support an effect of GI or GL on weight change. The positively significant association between GI, not GL, and subsequent gain in waist...

  11. Achieving HIV-1 Control through RNA-Directed Gene Regulation

    Vera Klemm

    2016-12-01

    Full Text Available HIV-1 infection has been transformed by combined anti-retroviral therapy (ART, changing a universally fatal infection into a controllable infection. However, major obstacles for an HIV-1 cure exist. The HIV latent reservoir, which exists in resting CD4+ T cells, is not impacted by ART, and can reactivate when ART is interrupted or ceased. Additionally, multi-drug resistance can arise. One alternate approach to conventional HIV-1 drug treatment that is being explored involves gene therapies utilizing RNA-directed gene regulation. Commonly known as RNA interference (RNAi, short interfering RNA (siRNA induce gene silencing in conserved biological pathways, which require a high degree of sequence specificity. This review will provide an overview of the silencing pathways, the current RNAi technologies being developed for HIV-1 gene therapy, current clinical trials, and the challenges faced in progressing these treatments into clinical trials.

  12. Muscle function in avian flight: achieving power and control

    Biewener, Andrew A.

    2011-01-01

    Flapping flight places strenuous requirements on the physiological performance of an animal. Bird flight muscles, particularly at smaller body sizes, generally contract at high frequencies and do substantial work in order to produce the aerodynamic power needed to support the animal's weight in the air and to overcome drag. This is in contrast to terrestrial locomotion, which offers mechanisms for minimizing energy losses associated with body movement combined with elastic energy savings to reduce the skeletal muscles' work requirements. Muscles also produce substantial power during swimming, but this is mainly to overcome body drag rather than to support the animal's weight. Here, I review the function and architecture of key flight muscles related to how these muscles contribute to producing the power required for flapping flight, how the muscles are recruited to control wing motion and how they are used in manoeuvring. An emergent property of the primary flight muscles, consistent with their need to produce considerable work by moving the wings through large excursions during each wing stroke, is that the pectoralis and supracoracoideus muscles shorten over a large fraction of their resting fibre length (33–42%). Both muscles are activated while being lengthened or undergoing nearly isometric force development, enhancing the work they perform during subsequent shortening. Two smaller muscles, the triceps and biceps, operate over a smaller range of contractile strains (12–23%), reflecting their role in controlling wing shape through elbow flexion and extension. Remarkably, pigeons adjust their wing stroke plane mainly via changes in whole-body pitch during take-off and landing, relative to level flight, allowing their wing muscles to operate with little change in activation timing, strain magnitude and pattern.

    分析2010年至2012年在本院内分泌科应用胰岛素快速控制血糖引起的急性痛性神经病变5例患者的临床资料及感觉定量和电生理研究等相关检查资料.结果显示,5例患者均为男性,年龄31~49岁,体重指数偏低,诊断为成人隐匿性自身免疫性糖尿病(LADA)或2型糖尿病患者.应用胰岛素前血糖控制很差,应用胰岛素后高血糖在短时间内纠正迅速,在胰岛素控制血糖期间常出现低血糖反应.肢体疼痛于应用胰岛素后2~4周内出现,经治疗2~6个月可部分或完全缓解.疼痛表现为刺痛、触痛,难以忍受,夜间明显.注射胰岛素几分钟后疼痛加重.应用弥可保、硫辛酸、前列地尔等药物治疗无明显好转.常伴有严重焦虑症状.神经肌电图检查显示双下肢胫、腓总神经运动传导速度正常或减慢,手足感觉阈值正常.%[Summary] The characteristics ot clinical data and relevant inspection (quantitative sensory and electrophysiological studies) in 5 patients hospitalized with acute painful neuropathy following rapid glycaemic control with insulin from 2010 to 2012 in our hospital were analyzed.The results showed that 5 patients were all males,aged 31-49 years,with lower body mass index,and diagnosed as latent autoimmune diabetes of adults (LADA) or type 2 diabetes.Glycaemic control was poor before application of insulin.When insulin was used,the hyperglycemia was rapidly corrected in a short time,with recurrent episodes of hypoglycemia during insulin treatment.The painful neuropathic symptoms appeared within 2-4 weeks after application of insulin,and were relieved partially or completely after 2-6 months.Neuropathic symptoms manifested as tingling and tenderness,with worsening during night and after insulin injection.The neuropathic symptoms were not significantly alleviated after application of neurotrophic drugs such as methycobal,protogen,and prostaglandin.These patients often suffered from severe

  14. Children's effortful control and academic achievement: do relational peer victimization and classroom participation operate as mediators?

    Valiente, Carlos; Swanson, Jodi; Lemery-Chalfant, Kathryn; Berger, Rebecca H

    2014-08-01

    Given that early academic achievement is related to numerous developmental outcomes, understanding processes that promote early success in school is important. This study was designed to clarify how students' (N=291; M age in fall of kindergarten=5.66 years, SD=0.39 year) effortful control, relational peer victimization, and classroom participation relate to achievement, as students progress from kindergarten to first grade. Effortful control and achievement were assessed in kindergarten, classroom participation and relational peer victimization were assessed in the fall of first grade, and achievement was reassessed in the spring of first grade. Classroom participation, but not relational peer victimization, mediated relations between effortful control and first grade standardized and teacher-rated achievement, controlling for kindergarten achievement. Findings suggest that aspects of classroom participation, such as the ability to work independently, may be useful targets of intervention for enhancing academic achievement in young children.

  15. Why achievement motivation predicts success in business but failure in politics: the importance of personal control.

    Winter, David G

    2010-12-01

    Several decades of research have established that implicit achievement motivation (n Achievement) is associated with success in business, particularly in entrepreneurial or sales roles. However, several political psychology studies have shown that achievement motivation is not associated with success in politics; rather, implicit power motivation often predicts political success. Having versus lacking control may be a key difference between business and politics. Case studies suggest that achievement-motivated U.S. presidents and other world leaders often become frustrated and thereby fail because of lack of control, whereas power-motivated presidents develop ways to work with this inherent feature of politics. A reevaluation of previous research suggests that, in fact, relationships between achievement motivation and business success only occur when control is high. The theme of control is also prominent in the development of achievement motivation. Cross-national data are also consistent with this analysis: In democratic industrialized countries, national levels of achievement motivation are associated with strong executive control. In countries with low opportunity for education (thus fewer opportunities to develop a sense of personal control), achievement motivation is associated with internal violence. Many of these manifestations of frustrated achievement motivation in politics resemble authoritarianism. This conclusion is tested by data from a longitudinal study of 113 male college students, showing that high initial achievement motivation combined with frustrated desires for control is related to increases in authoritarianism (F-scale scores) during the college years. Implications for the psychology of leadership and practical politics are discussed.

  19. The impact of a high versus a low glycaemic index breakfast cereal meal on verbal episodic memory in healthy adolescents.

    Smith, Michael A; Foster, Jonathan K

    2008-10-01

    In this study, healthy adolescents consumed either (i) a low glycaemic index breakfast cereal meal or (ii) a high glycaemic index breakfast cereal meal, before completing a test of verbal episodic memory in which the memory materials were encoded under conditions of divided attention. Analysis of remembering/forgetting indices revealed that the high glycaemic index breakfast group remembered significantly more items relative to the low glycaemic index breakfast group after a long delay. The superior performance observed in the high glycaemic index group, relative to the low glycaemic index group, may be due to the additional glucose availability provided by the high glycaemic index meal at the time of memory encoding. This increased glucose availability may be necessary for effective encoding under dual task conditions.

  3. Adding glycaemic index and glycaemic load functionality to DietPLUS, a Malaysian food composition database and diet intake calculator.

    Shyam, Sangeetha; Wai, Tony Ng Kock; Arshad, Fatimah

    2012-01-01

    This paper outlines the methodology to add glycaemic index (GI) and glycaemic load (GL) functionality to food DietPLUS, a Microsoft Excel-based Malaysian food composition database and diet intake calculator. Locally determined GI values and published international GI databases were used as the source of GI values. Previously published methodology for GI value assignment was modified to add GI and GL calculators to the database. Two popular local low GI foods were added to the DietPLUS database, bringing up the total number of foods in the database to 838 foods. Overall, in relation to the 539 major carbohydrate foods in the Malaysian Food Composition Database, 243 (45%) food items had local Malaysian values or were directly matched to International GI database and another 180 (33%) of the foods were linked to closely-related foods in the GI databases used. The mean ± SD dietary GI and GL of the dietary intake of 63 women with previous gestational diabetes mellitus, calculated using DietPLUS version3 were, 62 ± 6 and 142 ± 45, respectively. These values were comparable to those reported from other local studies. DietPLUS version3, a simple Microsoft Excel-based programme aids calculation of diet GI and GL for Malaysian diets based on food records.

  6. Variants in Pharmacokinetic Transporters and Glycaemic Response to Metformin

    Dujic, Tanja; Zhou, Kaixin; Yee, Sook Wah;

    2016-01-01

    Therapeutic response to metformin, a first-line drug for type 2 diabetes (T2D), is highly variable, in part likely due to genetic factors. To date, metformin pharmacogenetic studies have mainly focused on the impact of variants in metformin transporters genes, with inconsistent results. To clarify...... the significance of these variants in glycaemic response to metformin in T2D, we performed a large-scale meta-analysis across the cohorts of Metformin Genetics Consortium (MetGen). Nine candidate polymorphisms in five transporter genes (OCT1, OCT2, MATE1, MATE2-K and OCTN1) were analysed in up to 7,968 individuals....... None of the variants showed a significant effect on metformin response in the primary analysis, or in the exploratory secondary analyses, when patients were stratified according to possible confounding genotypes or prescribed metformin daily dose. Our results suggest that candidate transporters genes...

  8. How do different components of Effortful Control contribute to children's mathematics achievement?

    Sánchez-Pérez, Noelia; Fuentes, Luis J; Pina, Violeta; López-López, Jose A; González-Salinas, Carmen

    2015-01-01

    This work sought to investigate the specific contribution of two different components of Effortful Control (EC) -attentional focusing (AF) and inhibitory control- to children's mathematics achievement. The sample was composed of 142 children aged 9-12 year-old. EC components were measured through the Temperament in Middle Childhood Questionnaire (TMCQ; parent's report); math achievement was measured via teacher's report and through the standard Woodcock-Johnson test. Additionally, the contribution of other cognitive and socio-emotional processes was taken into account. Our results showed that only AF significantly contributed to the variance of children's mathematics achievement; interestingly, mediational models showed that the relationship between effortful attentional self-regulation and mathematics achievement was mediated by academic peer popularity, as well as by intelligence and study skills. Results are discussed in the light of the current theories on the role of children's self-regulation abilities in the context of school.

  10. Glycaemic and insulin responses, glycaemic index and insulinaemic index values of rice between three Asian ethnic groups.

    Tan, V M H; Wu, T; Henry, C J; Lee, Y S

    2015-04-28

    Asians exhibit larger glycaemic response (GR) and insulin response (IR) than Caucasians, predisposing to an increased risk of type 2 diabetes mellitus (T2DM). We aimed to determine the GR and IR as well as the glycaemic index (GI) and insulinaemic index (II) of two rice varieties among three ethnic groups in Singapore. A total of seventy-five healthy males (twenty-five Chinese, twenty-five Malay and twenty-five Asian-Indians) were served the available equivalent carbohydrate amounts (50 g) of test foods (Jasmine rice and Basmati rice) and a reference food (glucose) on separate occasions. Postprandial blood glucose and plasma insulin concentrations were measured at fasting ( -5 and 0 min) and at 15, 30, 45, 60, 90 and 120 min after food consumption. Using the trapezoidal rule, GR, IR, GI and II values were determined. The GR did not differ between ethnic groups for Jasmine rice and Basmati rice. The IR was consistently higher for Jasmine rice (P=0·002) and Basmati rice (P=0·002) among Asian-Indians, probably due to compensatory hyperinsulinaemia to maintain normoglycaemia. The GI and II of both rice varieties did not differ significantly between ethnicities. The overall mean GI for Jasmine rice and Basmati rice were 91 (sd 21) and 59 (sd 15), respectively. The overall mean II for Jasmine rice was 76 (sd 26) and for Basmati rice was 57 (sd 24). We conclude that the GI values presented for Jasmine rice and Basmati rice were applicable to all three ethnic groups in Singapore. Future studies should include deriving the II for greater clinical utility in the prevention and management of T2DM.

    The present research examined the protective role played by perceived control in the relation between depressive symptoms and academic achievement in adolescence. A sample of 218 adolescents aged 11 to 16 filled in questionnaires to assess self-reported depressive symptoms and three factors tied with Perceived Control (PC): self-regulated learning strategies use, effort attribution, and perceived competence. Grade Point Average (GPA) was considered as a measure of academic achievement. A path model showed that the relation between GPA and depressive symptoms is mediated by PC (plearning in planning programmes to prevent and treat depressive symptoms in adolescence.

  12. Estimation of secondary effect parameters in glycaemic dynamics using accumulating data from a virtual type 1 diabetic patient.

    Mansell, Erin J; Docherty, Paul D; Fisk, Liam M; Chase, J Geoffrey

    2015-08-01

    Some individuals with type 1 diabetes mellitus find self-managed glycaemic control difficult due to the confounding influence of secondary effects. Stress and sleep deprivation temporarily lower insulin sensitivity (SI), often resulting in hyperglycaemia, while aerobic exercise depletes glucose, leading to hypoglycaemia if treatment is unchanged. This study tests the estimation of these factors and circadian rhythms of SI in noisy data. Sparse, irregular and noisy virtual blood glucose data, mimicking the glycaemic dynamics of an individual with type 1 diabetes, was created via adapted pharmacokinetic-pharmacodynamic models of glucose and insulin that included the impact of the secondary effects. A Gauss-Newton algorithm was used to recover the original model parameters for SI, stress, fatigue and exercise. During longer identification periods, compensation was made for drift in SI. Monte Carlo analyses were undertaken to validate the methods. The coefficient of variation (CV) in all parameters decreased as the data accumulated in proportion to the 1/n rule (R(2) > 99.9%). Relatively small biases from the original parameter values occurred (data to override the effect of measurement error. Compensation for SI drift allows viable observation of secondary effects and SI rhythms over longer time periods. Collectively, these outcomes indicate that quality results for identified parameters could be obtained during in vivo studies.

    2016-01-01

    Full Text Available The aim of this study is to investigate the relationships between the affective learning needs namely, self-efficacy and locus of control, learning efforts and academic achievement among engineering students. For this purpose, a survey was conducted on first year engineering students from two technical universities in Malaysia. Self-efficacy and locus of control were assessed using existing instruments while learning efforts were assessed using a specifically designed instrument based on Carbonaro’s model of learning effort. Academic achievement data were based on cumulative grade point average (CGPA obtained from self-report by participants. The findings indicate that females engineering students tend to have higher self-efficacy compared to males while both groups have similar locus of control and invest in similar learning efforts. Only locus of control is found to be related to academic achievement while self-efficacy is found to be related to efforts. In conclusion, locus of control seems to be an important factor in predicting academic achievement among engineering students.

  14. Can aerobic exercise complement antihypertensive drugs to achieve blood pressure control in individuals with essential hypertension?

    Maruf, Fatai A; Salako, Babatunde L; Akinpelu, Aderonke O

    2014-06-01

    Achieving adequate blood pressure (BP) control with antihypertensive medication remains an elusive goal for many patients. The advances in knowledge of hypertension and the increasingly improved upon therapeutic strategies seem not to guarantee even sustainable control rates at the population level. In addition, patients who either discontinue their medications or are non-adherent to drug therapy run the risk of developing uncontrolled BP. Number of daily tablets more than two and number of daily drug administration at least three have been associated with poor adherence with drug therapy. However, BP control seems to go beyond adherence with drug therapy as there are other associated factors. Studies have demonstrated beneficial effect of aerobic exercise in the prevention and management of hypertension. It appears, however, that the majority of these studies failed to explore the possible additive or synergistic effect of aerobic exercise on antihypertensive drugs such that fewer drugs would be required to achieve BP control or that the BP control rate would be increased with the same number of drugs. This review presents the evidence for poor BP control in the general population, and the possible means and process of aerobic exercise complementing antihypertensive drug therapy in order to achieve higher BP control rates.

    2012-07-01

    Full Text Available The purpose of the study is to determine the relationships between locus of control (LOC orientation and high school students’ language achievement. The popular categorization of internals and externals was taken into account. The participants of this study were 121 high school students in the second, third and pre-university grades in two public high schools of Isfahan, Iran. One of the instruments used in the study was an adopted version of Julian Rotters’ locus of control (1966 which identified internal and external orientations. The participants’ English scores were regarded as the measure of their achievement. Besides, a questionnaire consisting of 29 items was administered to all 121 students. Responses were put into one way and two-way ANOVA, the regression analysis, the independent t-test, chi-square and linear regression analysis to compare the means of two sets of scores. The findings of this study show a significant relationship between locus control and achievement of high school students. The findings can be used by EFL teachers and syllabus designers.

  3. High school students' perceptions of EFL teacher control orientations and their English academic achievement.

    Kiany, Gholam Reza; Shayestefar, Parvaneh

    2011-09-01

    BACKGROUND. Theories distinguish between student-initiated and teacher-initiated regulation of students' learning activities, or between strong, shared, or loose teacher control during the completion of learning tasks. Empirical validations for such distinctions are scarce, however. AIM. The present study aimed at (a) investigating students' perceptions of control behaviours exhibited by their English teachers; and (b) exploring the contribution of different types of teacher control behaviours to students' cognitive outcomes (English Achievement). SAMPLE. The sample comprised 732 English as a Foreign Language (EFL) students studying in three major fields of high school (Mathematics, Natural Science, and Humanities). The participants (16-17 years of age) were selected from third-grade classes of 27 EFL teachers working in 25 high schools of 6 main different geographical regions in the Isfahan province, Iran. METHOD. To obtain a comprehensive picture of different control types exhibited by Iranian EFL teachers, the control subscales of the two existing questionnaires, i.e., the Questionnaire on Instructional Behaviours (QIB), adapted by Den Brok et al. (2004) and the Questionnaire on Lesson Activities (QLA) used by Den Brok (2001) were merged to form the Questionnaire of Teacher Control (QTC). The development of this Persian instrument involved several steps: translation and back translation by the researchers, one expert translator, and two EFL teachers; piloting; and a final administration of the questionnaire to the student sample. With respect to the second aim of the study, data regarding students' performances on the Standardized National English Achievement Tests were gathered from local educational offices and schools. RESULTS AND CONCLUSION. Statistical analyses supported acceptable reliability and validity of the instrument. A main factor structure with three types of teacher control (strong/high, shared/mid, and loose/low) was found to underlie students

    The core objective of the present work is to explore the reasons why workers from different employment sectors join training courses to improve their job. To this end we assessed achievement motivation, locus of control and professional qualifications according to the participants' employment sector. The final sample consisted of 1460 active Spanish workers from four different employment sectors: services, catering, metal construction, and others. Of the sample, 40.1% were male and 59.9% female, with a mean age of 33.3 years (SD = 9.7). The results show that the new scale developed to assess achievement motivation, locus of control and workers' qualifications presents adequate psychometric characteristics. Statistically significant differences were found in relation to employment sector. The areas studied showed satisfactory levels of workers' effort and achievement motivation to perform their jobs, though their attitudes toward the training courses as a basis for improving their employability are varied. Workers in the catering sector had higher levels of external attribution and the lowest interest in training. Those in the service sector had higher levels of achievement motivation and effort at work. Future research should develop a joint program covering the public and private sectors for the modification of these beliefs, attitudes and attributions.

  5. Building on the Enriched Hierarchical Model of Achievement Motivation: Autonomous and Controlling Reasons Underlying Mastery Goals

    2016-07-01

    Full Text Available Two motivational theories – the Achievement Goal Theory and Self-Determination Theory – have recently been combined to explain students’ motivation, making it possible to study the “what” and the “why” of learners’ achievement strivings. The present study built on this approach by (a investigating whether the distinction between autonomous or volitional and controlling or pressuring reasons can be meaningfully applied to the adoption of mastery-avoidance goals, (b investigating the concurrent and prospective relations between mastery-avoidance goals and their underlying reasons and learning strategies when mastery-approach goals and their underlying reasons were also considered, and by (c incorporating psychological need experiences as an explanatory variable in the relation between achievement motives (i.e., the motive to succeed and motive to avoid failure and both mastery goals and their underlying reasons. In two Turkish university students samples ('N' = 226, 'Mage '= 22.36; 'N' = 331, 'Mage '= 19.5, autonomous and controlling reasons appeared applicable to mastery-avoidance goals and regression and path analysis further showed that mastery-avoidance goals and their underlying autonomous reasons fail to predicted learning strategies over and above the pursuit of mastery-approach goals and their underlying reasons. Finally, need experiences were established as mediators between achievement motives and both mastery goals and their underlying reasons.

  6. Achieving 3-D Nanoparticle Assembly in Nanocomposite Thin Films via Kinetic Control

    2017-02-20

    Nanocomposite thin films containing well-ordered nanoparticle (NP) assemblies are ideal candidates for the fabrication of metamaterials. Achieving 3-D assembly of NPs in nanocomposite thin films is thermodynamically challenging as the particle size gets similar to that of a single polymer chain. The entropic penalties of polymeric matrix upon NP incorporation leads to NP aggregation on the film surface or within the defects in the film. Controlling the kinetic pathways of assembly process provides an alternative path forward by arresting the system in nonequilibrium states. Here, we report the thin film 3-D hierarchical assembly of 20 nm NPs in supramolecules with a 30 nm periodicity. By mediating the NP diffusion kinetics in the supramolecular matrix, surface aggregation of NPs was suppressed and NPs coassemble with supramolecules to form new 3-D morphologies in thin films. The present studies opened a viable route to achieve designer functional composite thin films via kinetic control.

    Introduction The monitoring of glycaemic status in patients with T2DM is mainly through blood tests (Fasting plasma glucose and HbA1c), which are invasive and involves painful pricks. This leads to poor patient compliance and soon could lead to various micro and macro vascular complications, which hamper the quality of life. There are no sensitive and specific markers to predict these complications at the earliest. Sialochemistry has recently gained attention for monitoring chronic diseases. Osteopontin is a phospho-glycoprotein molecule, elevated in many inflammatory conditions. Aim The aim of the study was to evaluate the role of serum and salivary osteopontin in Type 2 Diabetes mellitus (T2DM). Materials and Methods In this case-control study, we recruited 33 cases of T2DM and 31 age and gender matched healthy controls. Body Mass Index (BMI), Waist/Hip Ratio (WHR), Waist Circumference (WC) and blood pressure was recorded. Fasting Plasma Glucose (FPG), salivary glucose, HbA1c, microalbuminuria, systolic BP, serum and salivary osteopontin levels were estimated. Results FPG, salivary glucose, HbA1c, microalbuminuria, systolic BP, BMI, waist / hip ratio serum and salivary osteopontin levels were significantly high in T2DM cases compared to control subjects. Serum and salivary osteopontin levels were significantly correlated with HbA1c and microalbuminuria in T2DM cases. Conclusion Serum and salivary osteopontin levels are significantly elevated in subjects with T2DM and are associated with glycaemic control and microalbuminuria. PMID:27656430

    Low-glycaemic index diets reduce glycated Hb (HbA1c) in patients with type 2 diabetes, but require intensive dietary support. Using a liquid meal replacement with a low glycaemic response (GR) may be an alternative dietary approach. In the present study, we investigated whether breakfast replacement

    Christofides, Elena A

    2016-01-01

    In acromegaly, achieving biochemical control (growth hormone [GH] level acromegaly is challenging because it is rooted in observing subtle clinical manifestations, and it is typical for acromegaly to evolve for up to 10 years before it is recognized. This results in chronic exposure to elevated levels of GH and IGF-1 and delay in patients receiving appropriate treatment, which consequently increases mortality risk. In this review, the clinical impact of elevated GH and IGF-1 levels, the effectiveness of current therapies, and the potential role of novel treatments for acromegaly will be discussed. Clinical burden of acromegaly and benefits associated with management of GH and IGF-1 levels will be reviewed. Major treatment paradigms in acromegaly include surgery, medical therapy, and radiotherapy. With medical therapies, such as somatostatin analogs, dopamine agonists, and GH receptor antagonists, a substantial proportion of patients achieve reduced GH and normalized IGF-1 levels. In addition, signs and symptoms, quality of life, and comorbidities have also been reported to improve to varying degrees in patients who achieve biochemical control. Currently, there are several innovative therapies in development to improve patient outcomes, patient use, and access. Timely biochemical control of acromegaly ensures that the patient can ultimately improve morbidity and mortality from this disease and its extensive consequences. PMID:27471378

    This study was carried out to determine the blood glucose response and glycaemic index (GI) values of four types of commercially available breads in Malaysia. Twelve healthy volunteers (six men, six women; body mass index, 21.9±1.6 kg/m(2); age, 22.9±1.7 years) participated in this study. The breads tested were multi-grains bread (M-Grains), wholemeal bread (WM), wholemeal bread with oatmeal (WM-Oat) and white bread (WB). The subjects were studied on seven different occasions (four tests for the tested breads and three repeated tests of the reference food) after an overnight fast. Capillary blood samples were taken immediately before (0 min) and 15, 30, 45, 60, 90 and 120 min after consumption of the test foods. The blood glucose response was obtained by calculating the incremental area under the curve. The GI values were determined according to the standardized methodology. Our results showed that the M-Grains and WM-Oat could be categorized as intermediate GI while the WM and WB breads were high GI foods, respectively. The GI of M-Grains (56±6.2) and WM-Oat (67±6.9) were significantly lower than the reference food (glucose; GI = 100) (P food and the GI of WM (85±5.9) and WB (82±6.5) (P > 0.05). Among the tested breads, the GI values of M-Grains and WM-Oat were significantly lower (P foods.

  13. Concepts for Life Cycle Cost Control Required to Achieve Space Transportation Affordability and Sustainability

    Rhodes, Russel E.; Zapata, Edgar; Levack, Daniel J. H.; Robinson, John W.; Donahue, Benjamin B.

    2009-01-01

    Cost control must be implemented through the establishment of requirements and controlled continually by managing to these requirements. Cost control of the non-recurring side of life cycle cost has traditionally been implemented in both commercial and government programs. The government uses the budget process to implement this control. The commercial approach is to use a similar process of allocating the non-recurring cost to major elements of the program. This type of control generally manages through a work breakdown structure (WBS) by defining the major elements of the program. If the cost control is to be applied across the entire program life cycle cost (LCC), the approach must be addressed very differently. A functional breakdown structure (FBS) is defined and recommended. Use of a FBS provides the visibifity to allow the choice of an integrated solution reducing the cost of providing many different elements of like function. The different functional solutions that drive the hardware logistics, quantity of documentation, operational labor, reliability and maintainability balance, and total integration of the entire system from DDT&E through the life of the program must be fully defined, compared, and final decisions made among these competing solutions. The major drivers of recurring cost have been identified and are presented and discussed. The LCC requirements must be established and flowed down to provide control of LCC. This LCC control will require a structured rigid process similar to the one traditionally used to control weight/performance for space transportation systems throughout the entire program. It has been demonstrated over the last 30 years that without a firm requirement and methodically structured cost control, it is unlikely that affordable and sustainable space transportation system LCC will be achieved.

  14. Individual differences in inhibitory control, not non-verbal number acuity, correlate with mathematics achievement.

    Camilla Gilmore

    Full Text Available Given the well-documented failings in mathematics education in many Western societies, there has been an increased interest in understanding the cognitive underpinnings of mathematical achievement. Recent research has proposed the existence of an Approximate Number System (ANS which allows individuals to represent and manipulate non-verbal numerical information. Evidence has shown that performance on a measure of the ANS (a dot comparison task is related to mathematics achievement, which has led researchers to suggest that the ANS plays a critical role in mathematics learning. Here we show that, rather than being driven by the nature of underlying numerical representations, this relationship may in fact be an artefact of the inhibitory control demands of some trials of the dot comparison task. This suggests that recent work basing mathematics assessments and interventions around dot comparison tasks may be inappropriate.

  16. Achieving Closed-Loop Control Simulation of Human-Artefact Interaction: A Comparative Review

    Wilhelm Frederik van der Vegte

    2011-01-01

    Full Text Available To include user interactions in simulations of product use, the most common approach is to couple human subjects to simulation models, using hardware interfaces to close the simulation-control loop. Testing with virtual human models could offer a low-cost addition to evaluation with human subjects. This paper explores the possibilities for coupling human and artefact models to achieve fully software-based interaction simulations. We have critically reviewed existing partial solutions to simulate or execute control (both human control and product-embedded control and compared solutions from literature with a proof-of-concept we have recently developed. Our concept closes all loops, but it does not rely on validated algorithms to predict human decision making and low-level human motor control. For low-level control, validated solutions are available from other approaches. For human decision making, however, validated algorithms exist only to predict the timing but not the reasoning behind it. To identify decision-making schemes beyond what designers can conjecture, testing with human subjects remains indispensable.

  18. Achieving glycemic control in special populations in hospital: perspectives in practice.

    Cheng, Alice Y Y

    2014-04-01

    Achieving and maintaining glycemic control in patients with diabetes admitted to hospital is challenging because of the many competing factors of nutrition, pharmacotherapy and other patient-related and systemic factors. For patients receiving enteral or parenteral feeding, eating irregularly or receiving glucocorticoid therapy, the challenges are even greater. The basic principles to follow when managing glycemia in these populations are as follows: 1) Recognition of those at risk for hyperglycemia; 2) frequent bedside glucose monitoring; 3) a proactive approach with routine insulin administration based on the predicted glucose patterns; 4) constant reassessment of the glycemic status and titration of the routine insulin accordingly.

  1. The acute effects of a pulse-containing meal on glycaemic responses and measures of satiety and satiation within and at a later meal.

    2012-08-01

    Pulses are low glycaemic foods; however, their effect on satiation is unknown. The objective was to determine the effects of an ad libitum pulse meal on food intake (FI), appetite and blood glucose (BG) before and after a test meal (4 h later) and on FI at the test meal. Males (n 24, 22·8 kg/m2) received one of four treatments or control. The pulse treatments contained pasta and tomato sauce and 44 % of energy from: (1) chickpeas, (2) lentils, (3) navy beans or (4) yellow peas. The control was pasta and tomato sauce (pasta and sauce). FI (satiation) was measured at the treatment meal (0-20 min) and at an ad libitum pizza meal 4 h later. BG and appetite were measured from 0 to 340 min. At the treatment meal, lentils led to lower FI compared to chickpeas and pasta and sauce, whereas navy beans led to lower FI compared to chickpeas. Also, lentils led to lower cumulative FI compared to pasta and sauce. All pulses led to lower BG peak and cumulative area under the curve (AUC; 0-340 min); however, only chickpeas, lentils and navy beans reduced pre-pizza meal BG AUC (0-260 min) relative to pasta and sauce. Chickpeas led to lower post-pizza meal BG AUC (260-340 min) compared to navy beans and yellow peas. Consumption of pulses in a high-glycaemic meal contributes to earlier satiation, lower BG following the meal and after a later meal, but these effects are specific to pulse type and cannot be explained by their glycaemic properties alone.

  2. Rising methods and leavening agents used in the production of bread do not impact the glycaemic index.

    Fredensborg, Monica Hardman; Perry, Tracy; Mann, Jim; Chisholm, Alex; Rose, Meredith

    2010-01-01

    The aim of this study was to compare the glycaemic index of breads produced using different rising methods and leavening agents. Eleven bread varieties were selected based on method of production, and divided between three groups of ten participants (mean +/- SD age 30.0 +/- 10.7 years and BMI 22.9 +/- 2.8). Standard glycaemic index testing protocol was implemented after an overnight fast, using glucose as the reference food, and collecting blood samples over a two-hour period. Glycemic index was calculated using the usual method. Additionally, incremental area under the curve data were log transformed and glycaemic index was calculated using regression analysis. Mean glycaemic index values of the breads in ascending order were as follows: Swiss Rye; 60, Long oat; 68, Sourdough+oats; 71, Long rye; 76, Short oat; 77, Short whole meal; 78, Long whole meal; 80, Sourdough; 82, Short rye; 82, Yeast; 88, and Desem; 92. There were significant differences in mean glycaemic index values between Swiss Rye and Yeast (p = 0.010), Swiss Rye and Desem (p = 0.007) and Sourdough+oats and Desem (p = 0.043). The rising method and leavening agents used in this study did not impact on the glycaemic index of the breads tested. Other factors, such as increased bread density, and the addition of whole grains may be required to produce bread with a low glycaemic index.

  3. Operational scale entomological intervention for malaria control: strategies, achievements and challenges in Zambia

    2013-01-01

    Full Text Available Abstract Background While consensus on malaria vector control policy and strategy has stimulated unprecedented political-will, backed by international funding organizations and donors, vector control interventions are expansively being implemented based on assumptions with unequaled successes. This manuscript reports on the strategies, achievements and challenges of the past and contemporary malaria vector control efforts in Zambia. Case description All available information and accessible archived documentary records on malaria vector control in Zambia were reviewed. Retrospective analysis of routine surveillance data from the Health Management Information System (HMIS, data from population-based household surveys and various operations research reports was conducted to assess the status in implementing policies and strategies. Discussion and evaluation Empirical evidence is critical for informing policy decisions and tailoring interventions to local settings. Thus, the World Health Organization (WHO encourages the adoption of the integrated vector management (IVM strategy which is a rational decision making process for optimal use of available resources. One of the key features of IVM is capacity building at the operational level to plan, implement, monitor and evaluate vector control and its epidemiological and entomological impact. In Zambia, great progress has been made in implementing WHO-recommended vector control policies and strategies within the context of the IVM Global Strategic framework with strong adherence to its five key attributes. Conclusions The country has solid, consistent and coordinated policies, strategies and guidelines for malaria vector control. The Zambian experience demonstrates the significance of a coordinated multi-pronged IVM approach effectively operationalized within the context of a national health system.

    2014-01-01

    Panel mediation models and fixed-effects models were used to explore longitudinal relations among parents' reactions to children's displays of negative emotions, children's effortful control (EC), and children's math achievement (N = 291; M age in fall of kindergarten = 5.66 years, SD = .39 year) across kindergarten through second grade. Parents reported their reactions and children's EC. Math achievement was assessed with a standardized achievement test. First-grade EC mediated the relation between parents' reactions at kindergarten and second-grade math achievement, beyond stability in constructs across study years. Panel mediation model results suggested that socialization of EC may be one method of promoting math achievement in early school; however, when all omitted time-invariant covariates of EC and math achievement were controlled, first-grade EC no longer predicted second-grade math achievement.

  9. Achieving Energy Savings with Highly-Controlled Lighting in an Open-Plan Office

    Rubinstein, Francis; Enscoe, Abby

    2010-04-19

    An installation in a Federal building tested the effectiveness of a highly-controlled, workstation-specific lighting retrofit. The study took place in an open-office area with 86 cubicles and low levels of daylight. Each cubicle was illuminated by a direct/indirectpendant luminaire with three 32 watt lamps, two dimmable DALI ballasts, and an occupancy sensor. A centralized control system programmed all three lamps to turn on and off according to occupancy on a workstation-by-workstation basis. Field measurements taken over the course of several monthsdemonstrated 40% lighting energy savings compared to a baseline without advanced controls that conforms to GSA's current retrofit standard. A photometric analysis found that the installation provided higher desktop light levels than the baseline, while an occupant survey found that occupants in general preferred the lighting system to thebaseline.Simple payback is fairly high; projects that can achieve lower installation costs and/or higher energy savings and those in which greenhouse gas reduction and occupant satisfaction are significant priorities provide the ideal setting for workstation-specific lighting retrofits.

  10. A novel approach to achieving significant reverberation control in performance halls

    Conant, David A.; Chu, William

    2005-09-01

    Conventional methods for achieving broadband, variable sound absorption in large halls normally include heavy application of sound-absorptive drapery and/or thick fibrous panels, applied near available surfaces below, at, and in volumes above the catwalk plane. Occasionally, direct adjustments to room air volume are also provided to effect double-sloped decays. The novel method described here combines carefully located, broad scattering and absorption in singular architectural elements and was applied to a new, 1200-seat concert hall. A change of 0.70 s RT60 in midfrequency is achieved in a visually dramatic manner while neither materially changing room volume nor introducing often-maligned drapery. The aggregate of reverberation control methodologies employed reduces the unoccupied RT60 at midfrequencies from about 3.2 to 1.7 s in this space programed principally for music, including pipe organ.

    1997-06-01

    Full Text Available The primary objective of this study was to predict the work performance of Black managers by using three measures of Locus of Control and five measures of Achievement Motivation. Work performance was assessed by superiors with the aid of the Performance Appraisal Questionnaire of Schepers (1994 which yields three scores, viz, Work Performance, Creativity/Initiative and Management Skills. The sample comprised 102 Black male employees in supervisory and more senior positions in a diversified and geographically dispersed chemical company. In analysing the data, the three sets of measures were intercorrelated and subjected to a factor analysis. Three factors were identified; amongst others a factor representing work performance. A composite score was accordingly computed which served as the criterion measure in a regression analysis. Furthermore/ a canonical correlation procedure was used to maximise the correlation between the predictor variables and the dependent variables. Two statistically significant canonical correlations were obtained. It was found that both the Locus of Control Inventory and the Achievement Motivation Questionnaire can be used as predictors of work performance as assessed by means of the Performance Appraisal Questionnaire (PA.

    Green tea catechins are potent inhibitors of enzymes for carbohydrate digestion. However, the potential of developing low glycaemic index bakery food using green tea extract has not been investigated. Results of this study showed that addition of green tea extract (GTE) at 0.45%, 1%, and 2% concentration levels significantly reduced the glycaemic potential of baked and steamed bread. The average retention levels of catechins in the baked and steamed bread were 75.3-89.5% and 81.4-99.3%, respectively. Bread fortified with 2% GTE showed a significantly lower level of glucose release during the first 90 min of pancreatic digestion as well as a lower content of rapidly digested starch (RDS) content. A significantly negative correlation was found between the catechin retention level and the RDS content of bread. The potential of transforming bread into a low GI food using GTE fortification was proven to be promising.

  13. Methodology for adding and amending glycaemic index values to a nutrition analysis package.

    Levis, Sharon P

    2011-04-01

    Since its introduction in 1981, the glycaemic index (GI) has been a useful tool for classifying the glycaemic effects of carbohydrate foods. Consumption of a low-GI diet has been associated with a reduced risk of developing CVD, diabetes mellitus and certain cancers. WISP (Tinuviel Software, Llanfechell, Anglesey, UK) is a nutrition software package used for the analysis of food intake records and 24 h recalls. Within its database, WISP contains the GI values of foods based on the International Tables 2002. The aim of the present study is to describe in detail a methodology for adding and amending GI values to the WISP database in a clinical or research setting, using data from the updated International Tables 2008.

    Rosén, Liza

    2011-01-01

    The prevalence of metabolic disorders, such as type 2 diabetes, cardiovascular diseases and the insulin resistance syndrome (IRS) are increasing worldwide. However, disturbances in the metabolic status can be prevented by changing the daily diet towards more whole grains, vegetables, legumes and dairy products. Also the dietary glycaemic- and insulinaemic indices of foods may play a role. Rye products are interesting in this context as they are usually consumed in wholegrain form and have bee...

  16. Glycaemic indices of three Sri Lankan wheat bread varieties and a bread-lentil meal.

    Hettiaratchi, U P K; Ekanayake, S; Welihinda, J

    2009-01-01

    The glycaemic index (GI) concept ranks individual foods and mixed meals according to the blood glucose response. Low-GI foods with a slow and prolonged glycaemic response are beneficial for diabetic people, and several advantages have been suggested also for non-diabetic individuals. The recent investigations imply an increasing prevalence of diabetes mellitus in Sri Lanka. Thus, the present study was designed primarily to determine the glycaemic indices of some bread varieties in Sri Lanka as bread has become a staple diet among most of the urban people. A second objective was to observe the effects of macronutrients and physicochemical properties of starch on GI. Glycaemic responses were estimated according to FAO/WHO guidelines and both glucose and white bread were used as standards. Non-diabetic individuals aged 22-30 years (n=10) participated in the study. The test meals included white sliced bread, wholemeal bread, ordinary white bread and a mixed meal of wholemeal bread with lentil curry. The GI values (+/-standard error of the mean) of the meals were 77+/-6, 77+/-6, 80+/-4, 61+/-6, respectively (with glucose as the standard). The GI values of the bread varieties or the meal did not differ significantly (P >0.05). However, the meal can be categorized as a medium-GI food while the other bread varieties belong to the high-GI food group. A significant negative correlation was obtained with protein (P=0.042) and fat (P=0.039) contents of the food items and GI. Although the GI values of the foods are not significantly different, the inclusion of lentils caused the GI to decrease from a high-GI category to a medium-GI category. According to the present study, a ratio of 1.36 can be used to interconvert the GI values obtained with the two standards.

  17. The influence of maternal glycaemia and dietary glycaemic index on pregnancy outcome in healthy mothers.

    McGowan, Ciara A

    2010-07-01

    Infant birth weight has increased in Ireland in recent years along with levels of childhood overweight and obesity. The present article reviews the current literature on maternal glycaemia and the role of the dietary glycaemic index (GI) and its impact on pregnancy outcomes. It is known that maternal weight and weight gain significantly influence infant birth weight. Fetal macrosomia (birth weight >4000 g) is associated with an increased risk of perinatal trauma to both mother and infant. Furthermore, macrosomic infants have greater risk of being obese in childhood, adolescence and adulthood compared to normal-sized infants. There is evidence that there is a direct relationship between maternal blood glucose levels during pregnancy and fetal growth and size at birth, even when maternal blood glucose levels are within their normal range. Thus, maintaining blood glucose concentrations within normal parameters during pregnancy may reduce the incidence of fetal macrosomia. Maternal diet, and particularly its carbohydrate (CHO) type and content, influences maternal blood glucose concentrations. However, different CHO foods produce different glycaemic responses. The GI was conceived by Jenkins in 1981 as a method for assessing the glycaemic responses of different CHO. Data from clinical studies in healthy pregnant women have documented that consuming a low-GI diet during pregnancy reduces peaks in postprandial glucose levels and normalises infant birth weight. Pregnancy is a physiological condition where the GI may be of particular relevance as glucose is the primary fuel for fetal growth.

  18. The effect of dietary fibre on reducing the glycaemic index of bread.

    Scazzina, Francesca; Siebenhandl-Ehn, Susanne; Pellegrini, Nicoletta

    2013-04-14

    As bread is the most relevant source of available carbohydrates in the diet and as lowering dietary glycaemic index (GI) is considered favourable to health, many studies have been carried out in order to decrease the GI of bread. The most relevant strategy that has been applied so far is the addition of fibre-rich flours or pure dietary fibre. However, the effectiveness of dietary fibre in bread in reducing the GI is controversial. The purpose of the present review was to discuss critically the effects obtained by adding different kinds of fibre to bread in order to modulate its glycaemic response. The studies were selected because they analysed in vivo whether or not dietary fibre, naturally present or added during bread making, could improve the glucose response. The reviewed literature suggests that the presence of intact structures not accessible to human amylases, as well as a reduced pH that may delay gastric emptying or create a barrier to starch digestion, seems to be more effective than dietary fibre per se in improving glucose metabolism, irrespective of the type of cereal. Moreover, the incorporation of technologically extracted cereal fibre fractions, the addition of fractions from legumes or of specifically developed viscous or non-viscous fibres also constitute effective strategies. However, when fibres or wholemeal is included in bread making to affect the glycaemic response, the manufacturing protocol needs to reconsider several technological parameters in order to obtain high-quality and consumer-acceptable breads.

    Background Self-esteem and behavioral consequences, which are due to external or internal locus of control, are effective on academic achievement of students. Objectives The aim of this study was to determine the prediction of locus of control and self-esteem in academic achievement among the students. Materials and Methods This cross-sectional study was conducted on 300 college students in Kermanshah University of Medical Sciences in 2014. Data collection tools were in three sections: demographic, Rotter internal-external locus of control scale and Coopersmith self-esteem inventory. Data were analyzed using the SPSS software version 21. Results Results showed that 29.8% and 76.2% of the participants had internal locus of control, and high self-esteem, respectively. There was a significant correlation between self-esteem, locus of control and academic achievement of the students. Self-esteem accounted for 39.5% of the variation in academic achievement. Conclusions It seems that interventions to increase self-esteem among student can help improve academic achievement among them. PMID:27284277

  5. Using confirmatory factor analysis to understand executive control in preschool children: sources of variation in emergent mathematic achievement.

    Bull, Rebecca; Espy, Kimberly Andrews; Wiebe, Sandra A; Sheffield, Tiffany D; Nelson, Jennifer Mize

    2011-07-01

    Latent variable modeling methods have demonstrated utility for understanding the structure of executive control (EC) across development. These methods are utilized to better characterize the relation between EC and mathematics achievement in the preschool period, and to understand contributing sources of individual variation. Using the sample and battery of laboratory tasks described in Wiebe, Espy and Charak (2008), latent EC was related strongly to emergent mathematics achievement in preschool, and was robust after controlling for crystallized intellectual skills. The relation between crystallized skills and emergent mathematics differed between girls and boys, although the predictive association between EC and mathematics did not. Two dimensions of the child 's social environment contributed to mathematics achievement: social network support through its relation to EC and environmental stressors through its relation with crystallized skills. These findings underscore the need to examine the dimensions, mechanisms, and individual pathways that influence the development of early competence in basic cognitive processes that underpin early academic achievement.

  7. Children’s Self-Regulation and School Achievement in Cultural Contexts: The Role of Maternal Restrictive Control

    Mirjam eWeis

    2016-05-01

    Full Text Available Self-regulation can be developed through parent-child interactions and has been related to developmental outcomes, e.g. such as educational achievement. This study examined cross-cultural differences and similarities in maternal restrictive control, self-regulation (i.e., behavior and emotion regulation and school achievement and relations among these variables in Germany and Chile. Seventy-six German and 167 Chilean fourth graders, their mothers, and their teachers participated. Mothers and teachers rated children’s behavior regulation with a subscale of the Strengths and Difficulties Questionnaire. Children reported their use of emotion regulation strategies on the Questionnaire for the Measurement of Stress and Coping. Mothers rated maternal restrictive control by answering the Parenting Practice Questionnaire. School achievement was assessed by grades for language and mathematics. Results showed higher behavior regulation of German children in comparison to Chilean children and a higher preference of restrictive parental control in Chilean mothers than in German mothers. Regression analyses revealed positive relations between children’s behavior regulation and school achievement in Germany and in Chile. Further, in both cultural contexts, maternal restrictive control was related negatively to behavior regulation and positively to anger-oriented emotion regulation. In sum, the study showed the central function of behavior regulation for school achievement underlining negative relations of maternal restrictive control with children’s self-regulation and school achievement in diverse cultural contexts. Culturally adapted interventions related to parenting practices to promote children’s behavior regulation may assist in also promoting children’s school achievement.

    , que en 2011 concentraba en el 40% de la población nacional el 63% de los casos de tuberculosis. Las tasas en esta población han permanecido sin cambios durante los últimos 6 años. Además, la Región Metropolitana presenta zonas de muy alta incidencia, como son las comunas de Santiago (tasa 71,4 x 100.000, Estación Central (51,9 x 100.000, Independencia (46,8 x 100.000, San Joaquín (41,4 x 100.000 y Recoleta (35,3 x 100.000. Estas zonas pasan a ser prioritarias y requerirán de una intervención sanitaria más intensa y del reforzamiento de los equipos de tuberculosis en la atención primaria para que a través de la colaboración de todo su personal de salud aumenten la pesquisa bacteriológica de la tuberculosis pulmonar bacilífera.Tuberculosis continues to be a worldwide prevalent disease. Chile has established a tuberculosis control program since the earliest 70s which contributed to decrease the annual incidence of tuberculosis by 50% every decade, reaching the rate of 20 per 100.000 inhabitants the year 2000 ("early phase of tuberculosis elimination as a public health problem ". Unfortunately since this time the descent rate is becoming slower and between years 2009-2011 has achieved a stationary rate of13 x 100.000. This deterioration in the epidemiological situation of tuberculosis in Chile runs in parallel with the successive reductions in the budget assignedfor its control. A higher incidence of tuberculosis in high risk groups (HIVpopulation, migrants, prisoners and elderly people were not responsible for this epidemiologic deterioration. Lack of diagnosis in smear positive pulmonary tuberculosis patients is the most important source ofpersistent community infection. Only 25% of the estimated goal of sputum smear screening among medical consultations in primary care was achieved. Between the years 20062010 193.416 less sputum smear examinations were done. This means that nearly 966 smear positive tuberculosis patients were no identified as we know

  9. Power and Control in Kathmandu: A Comparison of Attempted Power, Actual Power, and Achieved Power.

    Emery, Clifton R; Thapa, Sirjana; Wu, Shali

    2016-05-05

    We argue that the concept of power has been inadvertently sidelined in recent theory and research on husband violence. Three types of relationship power may matter with respect to husband violence: attempted power, actual power, and achieved power. Analyses of a randomly selected representative sample of 270 married or partnered women in Kathmandu showed that actual power was related to husband violence prevalence, severity, and injury. Achieved power was related to husband violence prevalence and severity, and attempted power was related to husband violence injury. Implications are discussed.

  11. Control Method for Achieving High Power Factor in Single-Phase to Three-Phase Converters without Electrolytic Capacitors

    Yokoyama, Takahiro; Ohishi, Kiyoshi; Haga, Hitoshi; Shibata, Junji

    In this paper, we propose a method for the digital control of IPM motors in order to achieve a high power factor in single-phase to three-phase power converters without reactors or electrolytic capacitors. For achieving the unity power factor under any load condition and any speed condition, we propose a new digital control method that involves the use of a new feedback technique and a new feedforward technique on the source-current regulator side. The proposed digital control system is constructed by using DSP devices. In this paper, we also propose a new method for the compensation of one sampling delay time. The superior performance of the proposed method is demonstrated by experimental results. The experimental results were obtained using 1.5[kW] inverter system, which consists of a vector control system with a 14[μF] dc-link capacitor. The maximum power factor obtained in the experiments was 96.8[%].

    Full Text Available Online language education is a recent trend around the world. Investigating different factors that might affect learners’ success in this growing channel of education is a must. This study was an attempt to investigate the relationship between locus of control (LOC as a psychological construct and academic achievement of Iranian online learners of English as a Foreign Language (EFL. LOC is the extent to which individuals attribute their achievements either to external factors such as fate or to their own efforts. The participants of the study were 100 students studying English online at Iran Language Institute during 2013. The instrument used was Trice Academic LOC questionnaire which identifies orientations of internality or externality. The participants' grade point averages (GPAs were the measure of their academic achievement. The t-tests for the independent samples were performed on the data. The findings of this study revealed no significant relationship between LOC and academic achievement.

  13. Estimation of glycaemic index of peach palm (Bactris gasipaes) cooked fruits and chips, and pitahaya (Hylocereus spp.) pulp.

    Jiménez, Gin; Gómez, Georgina; Pérez, Ana M; Blanco-Metzler, Adriana

    2012-09-01

    The glycaemic index (GI) is a physiological measure of a food's potential to increase postprandial blood glucose, as compared to the effect produced by food taken as reference, such as glucose or white bread. Currently researchers and consumers are interested in low GI foods, since their consumption is associated with better weight control and reduced risk of incidence of chronic diseases, like diabetes. In the present study, the GI value for peach palm cooked fruit, peach palm chips and pitahaya pulp was estimated. The methodology established by the FAO/WHO for determining the GI of food was used. A total of 12 healthy, non-smoking volunteers were selected and they ingested the fore mentioned foods on different occasions, in 25 g portions of available carbohydrates, after 12-14 h overnight fast. Blood glucose levels were measured in 30 min intervals up to 120 min after ingestion. Average GI value was 48 +/- 11 for the pitahaya pulp and 35 +/- 6 for the peach palm cooked fruit, which may be classified as low glyceamic index foods. The GI of peach palm chips was 60 +/- 7, corresponding to a food with a moderate GI. The processing for producing the chips caused an increase in the GI value when compared to the cooked fruit, probably because the stages of miIling, moulding and baking promote availability of starch during hydrolysis by the digestive enzymes.

  16. Perceived Academic Control and Academic Emotions Predict Undergraduate University Student Success: Examining Effects on Dropout Intention and Achievement

    Respondek, Lisa; Seufert, Tina; Stupnisky, Robert; Nett, Ulrike E.

    2017-01-01

    The present study addressed concerns over the high risk of university students' academic failure. It examined how perceived academic control and academic emotions predict undergraduate students' academic success, conceptualized as both low dropout intention and high achievement (indicated by GPA). A cross-sectional survey was administered to 883 undergraduate students across all disciplines of a German STEM orientated university. The study additionally compared freshman students (N = 597) vs. second-year students (N = 286). Using structural equation modeling, for the overall sample of undergraduate students we found that perceived academic control positively predicted enjoyment and achievement, as well as negatively predicted boredom and anxiety. The prediction of dropout intention by perceived academic control was fully mediated via anxiety. When taking perceived academic control into account, we found no specific impact of enjoyment or boredom on the intention to dropout and no specific impact of all three academic emotions on achievement. The multi-group analysis showed, however, that perceived academic control, enjoyment, and boredom among second-year students had a direct relationship with dropout intention. A major contribution of the present study was demonstrating the important roles of perceived academic control and anxiety in undergraduate students' academic success. Concerning corresponding institutional support and future research, the results suggested distinguishing incoming from advanced undergraduate students. PMID:28326043

  17. Implementation and control of electrolysers to achieve high penetrations of renewable power

    Troncoso, E.; Newborough, M. [ITM Power plc, Orkney House, Great Chesterford Court, Great Chesterford, Saffron Walden CB10 1PF (United Kingdom)

    2007-09-15

    The mass deployment of electrolysers, within a power system serving a region of high wind resource, as the enabling mechanism for achieving five key objectives is assessed (that is: a very high installed capacity of wind power plant (WPP); zero wind curtailment during times of low demand; a very high load factor for thermal power plant; an electricity supply of low-carbon intensity; and a hydrogen supply of low-carbon intensity). Three electrolyser implementation cases were simulated for three days characterised mainly by wind availability and emphasis was placed on maximizing the smoothness of the load profile (LF) applied to thermal power plant. If zero-carbon hydrogen is to be produced a daily load factor for thermal power plant of 90% is the upper limit, but load factors of up to 100% are achievable if a carbon intensity of 3kgCO{sub 2}/kgH{sub 2} is permitted. For wind penetrations exceeding approximately 30% of system maximum demand, the electrolyser stock must include implementations close to WPP if curtailment is to be avoided. To achieve very high wind penetrations and very high load factors for thermal power plant requires a large stock of electrolysers - for the system investigated approximately 1.1 MW of electrolyser capacity is required per installed MW of wind power.

    Full Text Available Using personal potential is one of the key elements in behavior modification and the purpose of this research was to study the effects of a new method in changing human attitude and behavior in school context. Following this goal, in current research the authors have tried to examine the role of Step-by-Step Self-Regulation on studying behavior control, attitude to study and students' academic achievement. The total sample size was 120 high school male students in Hamedan. The subjects were divided into two groups: experimental group and control group. Then step-by-step self-regulation method were taught and carried out for eight sessions over the experimental group. Researcher made questionnaires were used for gathering data on study behavior control and students’ attitude to study and for evaluating students’ academic achievement their scholastic scores were used. In testing research hypotheses, a multivariate three-way ANOVA and independent and paired t tests were used. Comparing experimental and control groups data show that applying step-by-step self-regulation improves the personal ability to control study behavior while it does not have any meaningful effect on attitudes to study and students' academic achievement.

    ADAPT-NMR (Assignment-directed Data collection Algorithm utilizing a Probabilistic Toolkit in NMR) represents a groundbreaking prototype for automated protein structure determination by nuclear magnetic resonance (NMR) spectroscopy. With a [(13)C,(15)N]-labeled protein sample loaded into the NMR spectrometer, ADAPT-NMR delivers complete backbone resonance assignments and secondary structure in an optimal fashion without human intervention. ADAPT-NMR achieves this by implementing a strategy in which the goal of optimal assignment in each step determines the subsequent step by analyzing the current sum of available data. ADAPT-NMR is the first iterative and fully automated approach designed specifically for the optimal assignment of proteins with fast data collection as a byproduct of this goal. ADAPT-NMR evaluates the current spectral information, and uses a goal-directed objective function to select the optimal next data collection step(s) and then directs the NMR spectrometer to collect the selected data set. ADAPT-NMR extracts peak positions from the newly collected data and uses this information in updating the analysis resonance assignments and secondary structure. The goal-directed objective function then defines the next data collection step. The procedure continues until the collected data support comprehensive peak identification, resonance assignments at the desired level of completeness, and protein secondary structure. We present test cases in which ADAPT-NMR achieved results in two days or less that would have taken two months or more by manual approaches.

    Full Text Available Today, weeds control is very difficult because they are resistant to the herbicide due to excessive use of chemical herbicides in agriculture. Many studies have shown that mechanical and biological control of weeds can be much less damage to the environment of chemical herbicides. Develop of biological herbicides in agriculture was slow due to high prices and this subject the researchers to move toward the elimination of agricultural weed mechanically. This work was originally done by a many number of workers because and workers' rights didn’t work was ultimately economic value. Now solve this subject by the use of robotic technology in agriculture has been studied and a many number of agricultural researchers with the help of computer scientists move towards making robots to remove the weeds. Of course this is difficult due to excessive weeds similar to the plants, but the final results will help to increase crop and save the environment by eliminating chemical herbicides.

    The introduction of new rapid diagnostic tools for tuberculosis (TB) and the promising TB drugs pipeline together with the development of a new World Health Organization Strategy post 2015 allows new discussions on how to direct TB control. The European Respiratory Society's European Forum for TB Innovation was created to stimulate discussion on how to best take advantage of old and new opportunities, and advances, to improve TB control and eventually progress towards the elimination of TB. While TB control is aimed at reducing the incidence of TB by early diagnosis and treatment of infectious cases of TB, TB elimination requires focus on sterilising the pool of latently infected individuals, from which future TB cases would be generated. This manuscript describes the three core components that are necessary to implement the elimination strategy fully. 1) Improve diagnosis of latent TB infected individuals. 2) Improve regimens to treat latent TB infection. 3) ensure public health commitment to make both 1) and 2) possible. Old and new evidence is critically described, focusing on the European commitment to reach elimination and on the innovative experiences and best practices available.

  11. A procedure to achieve fine control in MW processing of foods

    Cuccurullo, G.; Cinquanta, L.; Sorrentino, G.

    2007-01-01

    A two-dimensional analytical model for predicting the unsteady temperature field in a cylindrical shaped body affected by spatially varying heat generation is presented. The dimensionless problem is solved analytically by using both partial solutions and the variation of parameters techniques. Having in mind industrial microwave heating for food pasteurization, the easy-to-handle solution is used to confirm the intrinsic lack of spatial uniformity of such a treatment in comparison to the traditional one. From an experimental point of view, a batch pasteurization treatment was realized to compare the effect of two different control techniques both based on IR thermography readout: the former assured a classical PID control, while the latter was based on a "shadowing" technique, consisting in covering portions of the sample which are hot enough with a mobile metallic screen. A measure of the effectiveness of the two control techniques was obtained by evaluating the thermal death curves of a strain Lactobacillus plantarum submitted to pasteurization temperatures. Preliminary results showed meaningful increases in the microwave thermal inactivation of the L. plantarum and similar significant decreases in thermal inactivation time with respect to the traditional pasteurization thermal treatment.

  12. Perceived Barriers to Application of Glycaemic Index: Valid Concerns or Lost in Translation?

    Shannan M. Grant

    2011-02-01

    Full Text Available The term glycaemic-index (GI originally appeared in the literature in the early 1980s. GI categorizes carbohydrate according to glycaemic effect postprandially. Since its inception, GI has obtained and maintained interest of academics and clinicians globally. Upon review of GI literature, it becomes clear that the clinical utility of GI is a source of controversy. Can and should GI be applied clinically? There are academics and clinicians on both sides of the argument. Certainly, this controversy has been a stimulus for the evolution of GI methodology and application research, but may also negatively impact clinicians’ perception of GI if misunderstood. This article reviews two assessments of GI that are often listed as barriers to application; the GI concept is (1 too complex and (2 too difficult for clients to apply. The literature reviewed does not support the majority of purported barriers, but does indicate that there is a call from clinicians for more and improved GI education tools and clinician GI education. The literature indicates that the Registered Dietitian (RD can play a key role in GI knowledge translation; from research to application. Research is warranted to assess GI education tool and knowledge needs of clinicians and the clients they serve.

  13. Bioavailability of milk protein-derived bioactive peptides: a glycaemic management perspective.

    Horner, Katy; Drummond, Elaine; Brennan, Lorraine

    2016-06-01

    Milk protein-derived peptides have been reported to have potential benefits for reducing the risk of type 2 diabetes. However, what the active components are and whether intact peptides exert this bioactivity has received little investigation in human subjects. Furthermore, potentially useful bioactive peptides can be limited by low bioavailability. Various peptides have been identified in the gastrointestinal tract and bloodstream after milk-protein ingestion, providing valuable insights into their potential bioavailability. However, these studies are currently limited and the structure and sequence of milk peptides exerting bioactivity for glycaemic management has received little investigation in human subjects. The present article reviews the bioavailability of milk protein-derived peptides in human studies to date, and examines the evidence on milk proteins and glycaemic management, including potential mechanisms of action. Areas in need of advancement are identified. Only by establishing the bioavailability of milk protein-derived peptides, the active components and the mechanistic pathways involved can the benefits of milk proteins for the prevention or management of type 2 diabetes be fully realised in future.

    2014-02-01

    Potatoes are usually a high-glycaemic index (GI) food. Finding a low-GI potato and developing a screening method for finding low-GI cultivars are both health and agricultural priorities. The aims of the present study were to screen the commonly used and newly introduced cultivars of potatoes, in a bid to discover a low-GI potato, and to describe the relationship between in vitro starch digestibility of cooked potatoes and their in vivo glycaemic response. According to International Standard Organisation (ISO) guidelines, seven different potato cultivars were tested for their GI. In vitro enzymatic starch hydrolysis and chemical analyses, including amylose content analysis, were carried out for each potato cultivar, and correlations with the respective GI values were sought. The potato cultivars had a wide range of GI values (53-103). The Carisma cultivar was classified as low GI and the Nicola cultivar (GI = 69) as medium GI and the other five cultivars were classified as high GI according to ISO guidelines. The GI values were strongly and positively correlated with the percentage of in vitro enzymatic hydrolysis of starch in the cooked potatoes, particularly with the hydrolysis percentage at 120 min (r 0·91 and P starch content was not correlated with either in vitro starch digestibility or GI. The findings suggest that low-GI potato cultivars can be identified by screening using a high-throughput in vitro digestion procedure, while chemical composition, including amylose and fibre content, is not indicative.

    Palladium (Pd) film containing nanogaps of well controlled dimension was fabricated on a Si wafer having a high-aspect-ratio micropillar. The Pd film was arranged to experience hydrogen (H{sub 2})-induced volume expansion. (i) If the nanogap is kept open, its width is narrowed down. A discharge current was generated to give a strong, fast, and repeatable on-off type resistive switching response. (ii) If the nanogap is closed, the cross section of the conduction path varies to give continuous H{sub 2}-concentration dependent resistive response. The influence of stresses and related physical mechanisms are discussed.

    2014-01-01

    On January 1, 2011, Princess Margaret Cancer Centre (PM) - University Health Network (UHN) began a five-year partnership agreement with the Kuwait Ministry of Health's Kuwait Cancer Control Center (KCCC) to enhance cancer care services. Over the course of the partnership, opportunities for improvement were identified by UHN experts in order to accelerate KCCC's development toward subspecialty cancer care. Many of these opportunities involved building a robust infrastructure to support foundational hospital operation processes and procedures. Harnessing UHN's own successes in accreditation, the partnership took advantage of the national accreditation mandate in Kuwait to initiate a quality program and drive clinical improvement at KCCC. This resulted in improved staff engagement, better awareness and alignment of administration with clinical management and a stronger patient safety culture. This article discusses the successes and lessons learned at KCCC that may provide insight to healthcare providers implementing Accreditation Canada International's accreditation framework in other countries and cultures.

    The objective of this investigation was to analyze the effectiveness of a quality improvement initiative in limiting the spread of multidrug-resistant organisms (MDROs) in the hospital setting. During the period 2011-2013, a multimodal intervention was activated at a tertiary care center in Italy. The intervention included: laboratory-based surveillance, interdisciplinary training sessions, monitoring the adoption of isolation precautions and daily supervision provided by infection control nurses, and a monthly feedback. Time series analysis was used to evaluate the trends and correlations between the MDROs rate, intensity of checking rounds, and hospital-wide data (i.e., transfer of patients, patients' days, site of isolation, etc.). A total of 149,251 patients were included in the study. The proportion of patients undergoing transmission-based isolation precautions within 24 h from a positive laboratory finding increased from 83% in 2011 to 99% in 2013 (p < 0.05). The wards appropriately adopting the correct isolation precaution increased from 83% in 2011 to 97.6% in 2013 (p < 0.05). The frequency of controls was significantly reduced after the observation of compliance in the appropriate wards (p < 0.05). After three years, the incidence rate changed from 5.8/1000 days of stay [95% confidence interval (CI) 5.6-6.1] in 2011 to 4.7 (95% CI 4.4-4.9) in 2013 (p < 0.0001). Moreover, microorganisms isolated from different types of specimens showed variable potential for transmission (i.e., skin as the most potential and urine the least). The results demonstrate the efficacy of the multimodal intervention, with sustained reduction of MDROs rate, besides check reduction, and highlight the long-term efficacy of checking rounds in changing professionals' behaviors.

  20. Achieving enhanced ionic mobility in nanoporous silica by controlled surface interactions.

    Garaga, Mounesha Nagendrachar; Aguilera, Luis; Yaghini, Negin; Matic, Aleksandar; Persson, Michael; Martinelli, Anna

    2017-02-22

    We report a strategy to enhance the ionic mobility in an emerging class of gels, based on robust nanoporous silica micro-particles, by chemical functionalization of the silica surface. Two very different ionic liquids are used to fill the nano-pores of silica at varying pore filling factors, namely one aprotic imidazolium based (1-methyl-3-hexylimidazolium bis(trifluoromethanesulfonyl)imide, C6C1ImTFSI), and one protic ammonium based (diethylmethylammonium methanesulfonate, DEMAOMs) ionic liquid. Both these ionic liquids display higher ionic mobility when confined in functionalized silica as compared to untreated silica nano-pores, an improvement that is more pronounced at low pore filling factors (i.e. in the nano-sized pore domains) and observed in the whole temperature window investigated (i.e. from -10 to 140 °C). Solid-state NMR, diffusion NMR and dielectric spectroscopy concomitantly demonstrate this effect. The origin of this enhancement is explained in terms of weaker intermolecular interactions and a consequent flipped-ion effect at the silica interface strongly supported by 2D solid-state NMR experiments. The possibility to significantly enhance the ionic mobility by controlling the nature of surface interactions is extremely important in the field of materials science and highlights these structurally tunable gels as promising solid-like electrolytes for use in energy relevant devices. These include, but are not limited to, Li-ion batteries and proton exchange membrane (PEM) fuel cells.

    In response to changing market dynamics, the discovery of new herbicides has declined significantly over the past few decades and has only seen a modest upsurge in recent years. Nevertheless, the few introductions have proven to be interesting and have brought useful innovation to the market. In addition, herbicide-tolerant or herbicide-resistant crop technologies have allowed the use of existing nonselective herbicides to be extended into crops. An increasing and now major challenge is being posed by the inexorable increase in biotypes of weeds that are resistant to herbicides. This problem is now at a level that threatens future agricultural productivity and needs to be better understood. If herbicides are to remain sustainable, then it is a must that we adopt diversity in crop rotation and herbicide use as well as increase the use of nonchemical measures to control weeds. Nevertheless, despite the difficulties posed by resistant weeds and increased regulatory hurdles, new screening tools promise to provide an upsurge of potential herbicide leads. Our industry urgently needs to supply agriculture with new, effective resistance-breaking herbicides along with strategies to sustain their utility.

  2. Combining independent, weighted P-values: achieving computational stability by a systematic expansion with controllable accuracy.

    Gelio Alves

    Full Text Available Given the expanding availability of scientific data and tools to analyze them, combining different assessments of the same piece of information has become increasingly important for social, biological, and even physical sciences. This task demands, to begin with, a method-independent standard, such as the P-value, that can be used to assess the reliability of a piece of information. Good's formula and Fisher's method combine independent P-values with respectively unequal and equal weights. Both approaches may be regarded as limiting instances of a general case of combining P-values from m groups; P-values within each group are weighted equally, while weight varies by group. When some of the weights become nearly degenerate, as cautioned by Good, numeric instability occurs in computation of the combined P-values. We deal explicitly with this difficulty by deriving a controlled expansion, in powers of differences in inverse weights, that provides both accurate statistics and stable numerics. We illustrate the utility of this systematic approach with a few examples. In addition, we also provide here an alternative derivation for the probability distribution function of the general case and show how the analytic formula obtained reduces to both Good's and Fisher's methods as special cases. A C++ program, which computes the combined P-values with equal numerical stability regardless of whether weights are (nearly degenerate or not, is available for download at our group website http://www.ncbi.nlm.nih.gov/CBBresearch/Yu/downloads/CoinedPValues.html.

    2016-03-01

    Progress made in malaria control during the past decade has prompted increasing global dialogue on malaria elimination and eradication. The product development pipeline for malaria has never been stronger, with promising new tools to detect, treat, and prevent malaria, including innovative diagnostics, medicines, vaccines, vector control products, and improved mechanisms for surveillance and response. There are at least 25 projects in the global malaria vaccine pipeline, as well as 47 medicines and 13 vector control products. In addition, there are several next-generation diagnostic tools and reference methods currently in development, with many expected to be introduced in the next decade. The development and adoption of these tools, bolstered by strategies that ensure rapid uptake in target populations, intensified mechanisms for information management, surveillance, and response, and continued financial and political commitment are all essential to achieving global eradication.

    This study compared the efficacy of isoflurane, sevoflurane, and desflurane in achieving hemodynamic stability in spinal procedures using moderate levels of controlled hypotension. After obtaining ethics committee approval and written informed consent, 32 American Surgical Association I-II patients were randomly allocated to receive isoflurane (n=12), sevoflurane (n=10), or desflurane (n=10) in O2-N2O (1:1) for maintenance of anesthesia. The induction of anesthesia, fentanyl dosage, and initial and maintenance volume replacements were standardized. Blood pressure was invasively monitored and maintained within a target systolic blood pressure (SBP) range of 80 to 90 mm Hg during the study. SBP outside this range was recorded. Volatile anesthetic concentration was adjusted according to the same protocol for all 3 agents. SPB control was maintained better with sevoflurane and isoflurane than desflurane; median SBP was outside the target range during 32% (range, 15%-55%) of study time with isoflurane, 26% (12%-42%) with sevoflurane, and 44% (20%-80%) with desflurane. Total blood loss did not differ among the groups. Sevoflurane and isoflurane administered in 2 L/min fresh gas flow were more effective than desflurane in achieving controlled hypotension in spinal surgery.

  7. Identification of those most likely to benefit from a low-glycaemic index dietary intervention in pregnancy.

    Walsh, Jennifer M

    2014-08-28

    The present study is a secondary analysis of the ROLO study, a randomised control trial of a low-glycaemic index (GI) diet in pregnancy to prevent the recurrence of fetal macrosomia. The objectives of the present study were to identify which women are most likely to respond to a low-GI dietary intervention in pregnancy with respect to three outcome measures: birth weight; maternal glucose intolerance; gestational weight gain (GWG). In early pregnancy, 372 women had their mid-upper arm circumference recorded and BMI calculated. Concentrations of glucose, insulin and leptin were measured in early pregnancy and at 28 weeks. At delivery, infant birth weight was recorded and fetal glucose, C-peptide and leptin concentrations were measured in the cord blood. Women who benefited in terms of infant birth weight were shorter, with a lower education level. Those who maintained weight gain within the GWG guidelines were less overweight in both their first and second pregnancies, with no difference being observed in maternal height. Women who at 28 weeks of gestation developed glucose intolerance, despite the low-GI diet, had a higher BMI and higher glucose concentrations in early pregnancy with more insulin resistance. They also had significantly higher-interval pregnancy weight gain. For each analysis, women who responded to the intervention had lower leptin concentrations in early pregnancy than those who did not. These findings suggest that the maternal metabolic environment in early pregnancy is important in determining later risks of excessive weight gain and metabolic disturbance, whereas birth weight is mediated more by genetic factors. It highlights key areas, which warrant further interrogation before future pregnancy intervention studies, in particular, maternal education level and inter-pregnancy weight gain.

  8. Achieving the nitrite pathway using FA inhibition and process control in UASB-SBR system removing nitrogen from landfill leachate

    2010-01-01

    An up-flow sludge blanket(UASB) and sequencing batch reactor(SBR) system was introduced to remove organics and nitrogen from landfill leachate.The synergetic effect of free ammonia(FA) inhibition and process control was used to achieve the nitrite pathway in the SBR.In previous research,inhibition of FA on nitrite oxidizing bacteria(NOB) activity has been revealed and the process control parameters(DO,ORP and pH) exactly indicate the end-point of nitritation.The method was implemented in the SBR achieving stable nitrogen removal via the nitrite pathway from landfill leachate.The degree of nitrite accumulation during the nitritation was monitored along with the simultaneous and advanced removal of organics and nitrogen in the UASB-SBR system.The nitrifying bacteria community was quantitatively analyzed by fluorescence in situ hybridization(FISH) techniques.Batch tests were carried out to investigate the denitritation kinetics of microbial bacteria in the SBR.Experimental results showed that the nitrite pathway could be repeatedly and reliably achieved by synergetic effect of FA inhibition and process control.FISH analysis showed the dominant nitrifying bacteria were ammonia-oxidizing β-Proteobacteria. Relationship between nitrite concentration and nitrite reduction rate followed the Monod-type equation.The maximum specific nitrite utilization rate(k) and half-velocity constant(Ks) were calculated as 0.44 gN gVSS-1d-1and 15.8 mg L-1,respectively.

    Early executive control (EC) predicts a range of academic outcomes and shows particularly strong associations with children's mathematics achievement. Nonetheless, a major challenge for EC research lies in distinguishing EC from related cognitive constructs that also are linked to achievement outcomes. Developmental cascade models suggest that children's information processing speed is a driving mechanism in cognitive development that supports gains in working memory, inhibitory control and associated cognitive abilities. Accordingly, individual differences in early executive task performance and their relation to mathematics may reflect, at least in part, underlying variation in children's processing speed. The aims of this study were to: (1) examine the degree of overlap between EC and processing speed at different preschool age points; and (2) determine whether EC uniquely predicts children's mathematics achievement after accounting for individual differences in processing speed. As part of a longitudinal, cohort-sequential study, 388 children (50% boys; 44% from low income households) completed the same battery of EC tasks at ages 3, 3.75, 4.5, and 5.25 years. Several of the tasks incorporated baseline speeded naming conditions with minimal EC demands. Multidimensional latent models were used to isolate the variance in executive task performance that did not overlap with baseline processing speed, covarying for child language proficiency. Models for separate age points showed that, while EC did not form a coherent latent factor independent of processing speed at age 3 years, it did emerge as a distinct factor by age 5.25. Although EC at age 3 showed no distinct relation with mathematics achievement independent of processing speed, EC at ages 3.75, 4.5, and 5.25 showed independent, prospective links with mathematics achievement. Findings suggest that EC and processing speed are tightly intertwined in early childhood. As EC becomes progressively decoupled from

    2014-01-01

    Full Text Available The fundamental idea of direct torque control of induction machines is investigated in order to emphasize the property produced by a given voltage vector on stator flux and torque variations. The proposed control system is based on Space Vector Modulation (SVM of electrical machines, Improvement model reference adaptive system, real time of stator resistance and estimation of stator flux. The purpose of this control is to minimize electromagnetic torque and flux ripple and minimizing distortion of stator current. In this proposed method, PI torque and PI flux controller are designed to achieve estimated torque and flux with good tracking and fast response with reference torque and there is no steady state error. In addition, design of PI torque and PI flux controller are used to optimize voltages in d-q reference frame that applied to SVM. The simulation Results of proposed DTC-SVM have complete excellent performance in steady and transient states as compared with classical DTC-SVM.

  11. Shifting from tuberculosis control to elimination: Where are we? What are the variables and limitations? Is it achievable?

    2017-03-01

    Full Text Available Tuberculosis (TB is a priority in terms of incidence and mortality, with about 10.4 million new incident cases and 1.8 million deaths in 2015. The End-TB strategy recently launched by the World Health Organization in the context of the post-2015 agenda, aimed to achieve TB elimination, represents an evolution of the previous historical strategies originally aimed to achieve TB control. Globally, the current decline in TB incidence is rather slow at approximately 1,5% per year to reach the TB pre-elimination phase by 2035 (A more aggressive approach based on diagnosis and treatment of latently infected individuals has been proposed in the context of TB elimination to ensure future generations free of TB. We describes 4 scenarios which, combined, describe the TB epidemiology in a given setting: 1 in absence of interventions, 2 with early TB diagnosis and effective treatment, 3 with irregular TB treatment, 4 with TB co-infected by HIV not undergoing anti-retroviral treatment. To achieve TB Elimination, a more concerted action by funders and governments will be required for further investments into TB prevention, detection and treatment.

    Ingwersen, Jeanet; Defeyter, Margaret Anne; Kennedy, David O; Wesnes, Keith A; Scholey, Andrew B

    2007-07-01

    This study investigated whether the glycaemic index (GI) of breakfast cereal differentially affects children's attention and memory. Using a balanced cross-over design, on two consecutive mornings 64 children aged 6-11 years were given a high GI cereal and a low GI cereal in a counterbalanced order. They performed a series of computerised tests of attention and memory, once prior to breakfast and three times following breakfast at hourly intervals. The results indicate that children's performance declines throughout the morning and that this decline can be significantly reduced following the intake of a low GI cereal as compared with a high GI cereal on measures of accuracy of attention (M=-6.742 and -13.510, respectively, p<0.05) and secondary memory (M=-30.675 and -47.183, respectively, p<0.05).

  13. Glycaemic effects of bread and marmalade in insulin-dependent diabetes.

    Lean, M E; Tennison, B R; Williams, D R

    1985-03-01

    The glycaemic responses of 12 C-peptide negative insulin-dependent diabetics were studied following four breakfasts with different carbohydrate sources. Total energy content of the meals was the usual for each subject, carbohydrate supplying 55% and fat 32%. The meals comprised: wholemeal bread with margarine; white bread with margarine; marmalade made with sucrose, and cheddar cheese; and marmalade (22% of total energy) on wholemeal bread with margarine. The study demonstrated powerfully that there were no statistically significant or clinically relevant differences between the meals in post-prandial glucose peak elevation, or in incremental area under the blood glucose curve to 120 mins. On these grounds, sucrose, in amounts considered acceptable to the general population, need not be prohibited from diabetic diets.

    This study considers the use of dry Jerusalem artichoke (JA) as a functional nutrient in developing food products with enhanced nutritional characteristics and low glycaemic index (GI). Three different formulations based on buckwheat and JA were developed and processed using extrusion technology. Nutritional properties including the levels of total dietary fibre (TDF), protein, inulin, total carbohydrates and lipids were analysed. A clinical study was performed on ten healthy volunteers (aged between 21 and 56) to determine the level of GI and glycaemic load (GL). The results revealed that JA significantly (Pfood and extruded products, GI and GL. Samples containing 80% of Jerusalem artichoke were considered as a low GI food whilst samples containing 30% and 60% of Jerusalem artichoke as a medium GI food. A similar trend was seen in terms of GL.

  16. Glycaemic responses to different types of bread in insulin-dependent diabetic subjects (IDDM): studies at constant insulinaemia.

    Rasmussen, O; Winther, E; Hermansen, K

    1991-02-01

    To study the glycaemic effect of various Danish bread types in insulin-dependent diabetic subjects (IDDM) we looked at the incremental blood glucose areas after isocaloric meals of grained wholemeal rye bread, wholemeal bread (graham bread) and white bread in seven C-peptide negative diabetic subjects. Furthermore, we evaluated the glycaemic potency of dried fruits by exchanging 40 per cent of the starch of grained wholemeal rye bread as dried figs. Prior to the meal intake the patients had attained normoglycaemia and isoinsulinaemia by means of the artificial pancreas. The four test meals containing 50 g of available carbohydrate were taken in random order. The postprandial blood glucose response areas after whole-meal bread (1037 +/- 113 mM X 180 min) and white bread (1021 +/- 100 mM X 180 min) were significantly higher than that to grained wholemeal rye bread (786 +/- 66 mM X 180 min, P less than 0.05). Exchange of 40 per cent of the complex carbohydrate as grained wholemeal rye bread with simple sugars, such as figs, had no influence on the blood glucose response (786 +/- 66 mM X 180 min vs. 766 +/- 56 mM X 180 min). Constant and identical serum-free insulin levels at 30 mU/l and similar amounts of glucose lost in the urine were found after the four test meals. In conclusion, the difference in extraction rate of wheat in the form of white flour (0, 7) and wholemeal flour (1, 0) was not reflected in the glycaemic responses in IDDM subjects. Grained wholemeal rye bread is a fibre-rich, cheap nutrient which elicits a significantly lower glycaemic response compared to wholemeal and white bread and can be recommended to diabetic subjects.

  20. Cognition, academic achievement, and epilepsy in school-age children: a case-control study in a developing country.

    Melbourne Chambers, R; Morrison-Levy, N; Chang, S; Tapper, J; Walker, S; Tulloch-Reid, M

    2014-04-01

    We conducted a case-control study of 33 Jamaican children 7 to 12years old with uncomplicated epilepsy and 33 of their classroom peers matched for age and gender to determine whether epilepsy resulted in differences in cognitive ability and school achievement and if socioeconomic status or the environment had a moderating effect on any differences. Intelligence, language, memory, attention, executive function, and mathematics ability were assessed using selected tests from NEPSY, WISCR, TeaCh, WRAT3 - expanded, and Raven's Coloured Progressive Matrices. The child's environment at home was measured using the Middle Childhood HOME inventory. Socioeconomic status was determined from a combination of household, crowding, possessions, and sanitation. We compared the characteristics of the cases and controls and used random effects regression models (using the matched pair as the cluster) to examine the relationship between cognition and epilepsy. We found that there was no significant difference in IQ, but children with epilepsy had lower scores on tests of memory (p<0.05), language (p<0.05), and attention (p<0.01) compared with their controls. In random effects models, epilepsy status had a significant effect on memory (coefficient=-0.14, CI: -0.23, -0.05), language (coefficient=-0.13, CI: -0.23, -0.04), and mathematics ability (coefficient=-0.01, CI: -0.02, -0.00). Adjustment for the home environment and socioeconomic status and inclusion of interaction terms for these variables did not alter these effects. In conclusion, we found that epilepsy status in Jamaican children has a significant effect on performance on tests of memory, language, and mathematics and that this effect is not modified or explained by socioeconomic status or the child's home environment.

  1. Association of Serum Selenium, Zinc and Magnesium Levels with Glycaemic Indices and Insulin Resistance in Pre-diabetes: a Cross-Sectional Study from South India.

    2017-01-01

    A growing understanding of antioxidant mechanisms and insulin-like actions of trace elements selenium and zinc has rekindled researchers' interest towards their role in diabetes mellitus, nutritional management of which concentrates predominantly on macronutrient intake. However, selenium studies limiting largely to diabetes have yielded inconsistent results with sparse knowledge in the pre-diabetes population. This hospital-based cross-sectional study screened 300 people who came to the institutional hospital laboratory with fasting plasma glucose and glycosylated haemoglobin requisition over a period of 6 months. Thirty-five pre-diabetes subjects aged 25-45 years and 35 age-matched healthy controls were selected as per inclusion criteria and clinical history. Serum selenium was estimated by inductively coupled plasma-mass spectrometry, zinc and magnesium by colorimetric end-point methods and insulin by enzyme-linked immunosorbent assay, and insulin resistance was calculated using a homeostasis model assessment (HOMA) 2 calculator. Data analysis was done using SPSS ver. 16 employing an independent sample t test for intergroup comparison of means and Pearson's correlation for correlation analysis. Serum mineral levels in the pre-diabetes group (selenium 63.01 ± 17.6 μg/L, zinc 55.78 ± 13.49 μg/dL, magnesium 1.37 ± 0.38 mg/dL) were significantly reduced (p zinc 94.53 ± 15.41 μg/dL, magnesium 2.12 ± 0.22 mg/dL). A significant negative correlation was seen with glycaemic indices and insulin resistance. This study conducted in pre-diabetes subjects highlights a considerable deficiency of serum selenium, zinc and magnesium observed at a much earlier pre-clinical phase. This coupled with the evidence of a strong inverse association with glycaemic indices and insulin resistance postulates the role of mineral alterations in the pathophysiology of hyperglycaemia and insulin resistance.

In light of the global TB epidemic and control environment, it is useful to review the TB control priorities of the project, summarize the achievements and experiences around its implementation.

  4. Diet e ect on short- and long-term glycaemic response in adult healthy cats.

    Musco, Nadia; Calabro, Serena; Tudisco, Raffaella; Grossi, Micaela; Addi, Laura; Moniello, Giuseppe; Lombardi, Pietro; Cutrignelli, Monica Isabella

    2016-08-03

    In the paper the short- and long-term glycaemic response after 4 diet programmes was evaluated. Each diet programme was alternatively administered to 6 healthy cats for 30 days. At the end of each period cats were weighed and underwent blood sampling for glucose and fructosamine determination. Glycaemia was measured every 2 hours for 24 hours using an automated glucometer. Very high protein level and low starch (VHP/LS) and high protein and moderate starch level (HP/LS) diets showed glucose (Mean and Peak) and fructosamine values signi cantly lower compared to the moderate protein and high starch diets (MP/HS). It is likely that these results are due to the contemporary e ect of the following nutritional characteristics: protein level, protein/starch ratio and dietary bre. All these parameters were higher in VHP/LS and HP/MS diets. These preliminary results suggest that the use of diets with high protein/starch ratio and soluble bre levels favours the carbohydrate metabolism of healthy cats.

    Full Text Available Aim. An exploration of ethnic differences in measures of oxidative stress and endothelial activation in relation to known cardiovascular risk factors within South Asians (SA and White Europeans (WE residing in the UK. Methods. 202 participants within a UK multiethnic population provided biomedical and anthropometric data. Human urinary 2,3-dinor-8-iso-prostaglandin-F1α and plasma ICAM-1 were quantified as measures of oxidative stress and endothelial activation, respectively. Results. 2,3-Dinor-8-iso-prostaglandin-F1α levels were significantly higher in the SA group compared to WE group (10.36 (95% CI: 9.09, 11.79 versus 8.46 (7.71, 9.29, P=0.021 after adjustment for age, gender, smoking status, body weight, HbA1c, and medication. Oxidative stress was positively associated with HbA1c (β=1.08, 95% CI:1.02, 1.14, P=0.009, fasting (β=1.06, 95% CI: 1.02, 1.10, P=0.002, and 2 hr glucose (β=1.02, 95% CI: 1.00, 1.04, P=0.052. In each adjusted model, SA continued to have elevated levels of oxidative stress compared to WE. ICAM-1 levels were significantly higher in the composite IGR group compared to the normoglycaemic group (P<0.001. No ethnic differences in ICAM-1 were observed. Conclusion. These results suggest that SA are more susceptible to the detrimental effects of hyperglycaemia-induced oxidative stress at lower blood glucose thresholds than WE. Further research into the potential mechanisms involved is warranted.

    Plasma total cysteine (tCys) is strongly and independently associated with obesity in large human cohorts, but whether the association is causal is unknown. Dietary cyst(e)ine increases weight gain in some rodent models. We investigated the body composition, metabolic rate and metabolic phenotype of mature C3H/HeH mice assigned to low-cystine (LC) or high-cystine (HC) diets for 12 weeks. Compared to LC mice, HC mice gained more weight (P=.004 for 12-week weight gain %), with increased fat mass and lean mass, and lowered O₂ consumption and CO₂ production by calorimetry. The HC mice had 30% increase in intestinal fat/body weight % (P=.003) and ∼twofold elevated hepatic triglycerides (P=.046), with increased expression of hepatic lipogenic factors, peroxisome proliferator-activated receptor-γ and sterol regulatory element binding protein-1. Gene expression of both basal and catecholamine-stimulated lipolytic enzymes, adipose triglyceride lipase and hormone-sensitive lipase was inhibited in HC mice adipose tissue. The HC mice also had elevated fasting glucose (7.0 vs. 4.5 mmol/L, Pcystine intake promotes adiposity and an adverse metabolic phenotype in mice, indicating that the positive association of plasma tCys with obesity in humans may be causal.

  18. What "No Child Left Behind" Leaves behind: The Roles of IQ and Self-Control in Predicting Standardized Achievement Test Scores and Report Card Grades

    Duckworth, Angela L.; Quinn, Patrick D.; Tsukayama, Eli

    2012-01-01

    The increasing prominence of standardized testing to assess student learning motivated the current investigation. We propose that standardized achievement test scores assess competencies determined more by intelligence than by self-control, whereas report card grades assess competencies determined more by self-control than by intelligence.

  19. Relationships between high-stakes testing policies and student achievement after controlling for demographic factors in aggregated data.

    Gregory J. Marchant

    2006-11-01

    Full Text Available With the mandate of No Child Left Behind, high-stakes achievement testing is firmly in place in every state. The few studies that have explored the effectiveness of high-stakes testing using NAEP scores have yielded mixed results. This study considered state demographic characteristics for each NAEP testing period in reading, writing, mathematics, and science from 1992 through 2002, in an effort to examine the relation of high-stakes testing policies to achievement and changes in achievement between testing periods. As expected, demographic characteristics and their changes were related significantly to most achievement outcomes, but high-stakes testing policies demonstrated few relationships with achievement. The few relationships between high-stakes testing and achievement or improvement in reading, writing, or science tended to appear only when demographic data were missing; and the minimal relationships with math achievement were consistent with findings in previous research. Considering the cost and potential unintended negative consequences, high-stakes testing policies seem to provide a questionable means of improving student learning.

  20. The effect of food with different glycaemic index on the blood glucose level

    Lenka Kouřimská

    Full Text Available Blood glucose levels are affected by many factors including the type of foods consumed, processing technology and cooking method. Hormone insulin lowers blood glucose to its constant level, while glucagon, growth hormone, adrenalin and glucocorticoids have the opposite effect. High steepness of the blood glucose level rise after meals may be unfavourable for the organism. Sugars are transferred into the blood at different speeds according to the type of food. Therefore the aim of this study was to confirm experimentally the effect of food on blood glucose levels in men and women of different ages. Two types of low, medium and high-glycaemic index (GI foods were given to 4 men and 4 women of different age (from 35 to 65 years. All volunteers were healthy, slightly overweight, and without any regular sporting activity. None of them had any idea about their daily carbohydrates consumption and what the term glycaemic index meant. The volunteers came to the GI determination fasted in the morning. Their rise in blood glucose level was monitored by glucometer before the meal and after 1 and 2 hours of the consumption of baked potatoes (GI 85, white bread bun (GI 70, boiled potatoes (GI 64, rye bread (GI 62, potato dumplings (GI 52 and white cooked spaghetti (GI 41. Fasting blood sugar levels of volunteers highly depended on their age (p <0.0001 and gender (p <0.0001. The blood glucose values increased with age and were higher in men than in women. Significant influence of food GI on blood glucose levels in both men and women in all the age categories was observed (p <0.0001. An interaction between age and gender was also statistically highly significant (p <0.0001. One hour after consuming food the blood glucose values were significantly different from the values of fasting (p = 0.0035. The differences of these values did not depend on the age (p = 0.0574 and sex (p = 0.8256 of volunteers, but there was a significant difference on the GI value of food

    2007-12-01

    This work was aimed at decreasing the glycaemic index (GI) of white wheat bread. Breads made with wheat flour (WF) or wholemeal flour (WMF) and fermented with baker's yeast had similar values of resistant starch (RS; 1.4-1.7 %, starch basis). Sourdough Lactobacillus plantarum P1 and Lactobacillus brevis P2 favoured the highest formation of RS (approximately 5 %) when fermented with WF and WMF. The mixture (1:1) of WF and WMF (WF/WMF) was selected. The effect of dietary fibres, chemical or sourdough acidification on the hydrolysis index (HI) of WF/WMF bread was determined. Among fibres, only the addition of oat fibre (5 %) decreased the HI to 90.84 %. Lactic acid determined the lowest HI, and the effect was related to the decrease of pH. For the same decrease of pH, breads fermented with L. plantarum P1 and L. brevis P2 (sourdough WF/WMF) showed values of HI lower than chemical acidification. The glucose response and GI of WF bread or sourdough WF/WMF bread enriched with oat fibre was determined by using fifteen healthy volunteers. Anhydrous glucose was used as reference. The area under the glucose response curve and the value of GI (72 %) of WF bread were significantly (P sourdough WF/WMF bread enriched with oat fibre (GI = 53.7 %). The decrease of GI of the sourdough WF/WMF bread may be due to both fibre content and decreased pH. Compared to WMF bread, sourdough WF/WMF bread, enriched with oat fibre, had higher specific volume, better cell crumb structure and more appreciated acidulous smell, taste and aroma.

  2. Fermentation as a Means of Optimizing the Glycaemic Index - Food Mechanisms and Metabolic Merits with Emphasis on Lactic Acid in Cereal Products

    Östman, Elin

    2003-01-01

    In current recommendations from FAO/WHO, foods that elicit low glycaemic responses and thus have low glycaemic indices (GIs) are advocated. The rationale for this recommendation is that low-GI diets have been shown to reduce risk factors for e.g. type II diabetes and cardiovascular disease. A major problem in this context is that most important starch rich staple foods in our diet, such as potato and bread products, have high GIs. One important task is, therefore, to identify food factors tha...

  3. Enrichment of an Israeli ethnic food with fibres and their effects on the glycaemic and insulinaemic responses in subjects with non-insulin-dependent diabetes mellitus.

    1995-11-01

    The effects of various sources of dietary fibre on the high glycaemic index of an Israeli ethnic food, melawach, were investigated in subjects with non-insulin-dependent diabetes mellitus (NIDDM). Locust-bean (Ceratonia siliqua) gum significantly decreased the glucose response to, and glycaemic index of, melawach in these diabetic subjects (P 30 kg/m2, whereas insulinaemic response decreased. The results indicate that foods containing the same nutrients in almost the same amounts, but differing in added dietary fibre, lead to different physiological responses in diabetic subjects. Furthermore, insulin response should be considered when fibre is incorporated into the diabetic's diet.

  6. Control-value theory: using achievement emotions to improve understanding of motivation, learning, and performance in medical education: AMEE Guide No. 64.

    Artino, Anthony R; Holmboe, Eric S; Durning, Steven J

    2012-01-01

    In this AMEE Guide, we consider the emergent theoretical and empirical work on human emotion and how this work can inform the theory, research, and practice of medical education. In the Guide, we define emotion, in general, and achievement emotions, more specifically. We describe one of the leading contemporary theories of achievement emotions, control-value theory (Pekrun 2006), and we distinguish between different types of achievement emotions, their proximal antecedents, and their consequences for motivation, learning, and performance. Next, we review the empirical support for control-value theory from non-medical fields and suggest several important implications for educational practice. In this section, we highlight the importance of designing learning environments that foster a high degree of control and value for students. Finally, we end with a discussion of the need for more research on achievement emotions in medical education, and we propose several key research questions we believe will facilitate our understanding of achievement emotions and their impact on important educational outcomes.

  7. Effect of coffee and tea on the glycaemic index of foods: no effect on mean but reduced variability.

    Aldughpassi, Ahmed; Wolever, Thomas M S

    2009-05-01

    Coffee and tea may influence glycaemic responses but it is not clear whether they affect the glycaemic index (GI) value of foods. Therefore, to see if coffee and tea affected the mean and SEM of GI values, the GI of fruit leather (FL) and cheese puffs (CP) were determined twice in ten subjects using the FAO/WHO protocol with white bread as the reference food. In one series subjects chose to drink 250 ml of either coffee or tea with all test meals, while in the other series they drank 250 ml water. The tests for both series were conducted as a single experiment with the order of all tests being randomised. Coffee and tea increased the overall mean peak blood glucose increment compared with water by 0.25 (SEM 0.09) mmol/l (P=0.02), but did not significantly affect the incremental area under the glucose response curve. Mean GI values were not affected by coffee or tea but the SEM was reduced by about 30% (FL: 31 (SEM 4) v. 35 (SEM 7) and CP: 76 (SEM 6) v. 75 (SEM 8) for coffee or tea v. water, respectively). The error mean square term from the ANOVA of the GI values was significantly smaller for coffee or tea v. water (F(18, 18) = 2.31; P=0.04). We conclude that drinking coffee or tea with test meals does not affect the mean GI value obtained, but may reduce variability and, hence, improve precision.

  8. Dietary approach to hypertension based on low glycaemic index and principles of DASH (Dietary Approaches to Stop Hypertension): a randomised trial in a primary care service.

    2013-10-01

    Hypertension is one of the leading causes of morbidity and mortality in Brazil. Diet may play an important role in reducing blood pressure (BP), as has been shown for diets high in fruits, vegetables and low-fat dairy products and low in salt (Dietary Approaches to Stop Hypertension (DASH)-Na). A low-glycaemic index Brazilian diet combined with the principles of the DASH-Na diet was evaluated in a randomised study of 206 individuals who were followed for 6 months. In the control group (CG), counselling was based on standard care and mainly focused on salt intake reduction. An intention-to-treat analysis showed that, after 6 months, systolic BP was reduced by 14·4 mmHg and diastolic BP by 9·7 mmHg in the experimental group (EG), compared with 6·7 and 4·6 mmHg, respectively, in the CG. After adjusting for body weight, BP at baseline and age, these changes were 12·1 and 7·9 mmHg, respectively. Urinary Na excretion was also reduced by 43·4 mEq/24 h in the EG. Food intake was modified accordingly during the intervention with an increase in the consumption of vegetables (2·97-5·85 frequency of consumption measured in three non-consecutive days), fruits (4·09-7·18), beans (1·94-3·13) and fish (1·80-2·74) by the EG. The present study showed the feasibility of a Brazilian dietary approach to treating hypertension by reducing urinary Na excretion and BP, changes that may have a great impact on public health and promote the benefits of controlling hypertension.

  10. The glycaemic index: importance of dietary fibre and other food properties.

    Björck, Inger; Elmståhl, Helena Liljeberg

    2003-02-01

    An increasing body of evidence suggests that a low-glycaemic-index (GI) diet has a therapeutic as well as a preventive potential in relation to the insulin resistance syndrome. The implementation of a low-GI diet, however, will require an extended list of low-GI foods to be available on the market. The tailoring of low-GI bread products offers a particular challenge due to their generally high GI and abundance in the diet. Low-GI bread products can be tailored by, for example,enclosure of cereal kernels, sour dough fermentation and/or addition of organic acids, or use of cereal genotypes with elevated contents of amylose or f-glucans. Low-GI cereal foods appear to vary in effect on 'second-meal' glucose tolerance in healthy subjects. In addition to the slow-release properties of such foods, the content of dietary fibre appears to play a role. The low glycaemia to starch in a pasta breakfast (GI 54) promoted a higher glucose tolerance and lowered triacylglycerol levels at a standardized lunch ingested 4 h later, compared with a white-wheat-bread breakfast (GI 100). The metabolic benefits of the low GI properties per se have been demonstrated also in the longer term. Thus, a reduction in dietary GI improved glucose and lipid metabolism and normalized fibrinolytic activity in type 2 diabetics, while maintaining a similar amount and composition of dietary fibre. However, the higher dietary fibre content frequently associated with low-GI foods may add to the metabolic merits of a low-GI diet. Consequently, a low-GI barley meal rich in dietary fibre (GI 53) improved glucose tolerance from evening meal to breakfast, whereas an evening meal with pasta had no effect (GI 54). The exchange of common high-GI bread for low-GI high-fibre bread, as the only dietary modification, improved insulin economy in women at risk of type 2 diabetes. These results are in accordance with epidemiological evidence of a reduced risk of type 2 diabetes with a low-GI diet rich in cereal fibre. It

  11. Oral versus intubated feeding and the effect on glycaemic and insulinaemic responses, gastric emptying and satiety.

    Morey, S; Shafat, A; Clegg, M E

    2016-01-01

    Cephalic phase responses (CPR) are important in early initiation of digestion and maximal absorption of nutrients prior to ingestion. Bypassing CPR has been shown to have consequences on metabolic responses that may influence satiety. The aim of this study was to investigate if using gastric intubation to bypass oro-pharyngeal and oesophageal exposure would reduce CPR including insulin and blood glucose and whether these impact on gastric emptying and satiety. Ten male subjects were tested on 2 occasions, 3-7 days apart after an overnight fast, in randomized order. Subjects were cannulated and intubated with a gastric tube for both tests. For test one, subjects ate 400 ml soup with a spoon and for test two the soup was infused into the stomach at an equivalent rate. Subsequently measurements of glycaemic (GR) and insulinaemic responses (IR) from cannula samples, breath samples for measurement of gastric emptying using the [(13)C] sodium acetate breath test and visual analogue scales (VAS) for satiety were taken over 180 min. There were differences in IR over the first 15 min (Oral: 169.0 ± 22.1; Gastric 124.1 ± 18.8; t(9) = 2.67; p = 0.028) but no difference in GR. There were differences in gastric emptying half time (Oral: 85.0 ± 2.7; Gastric 79.4 ± 3.3; t(9) = 2.40; p = 0.04) and ascension time (Oral: 68.2 ± 2.2; Gastric 64.0 ± 2.2; t(9) = 2.57; p = 0.03) with food taking longer to empty from the stomach on the Oral test day than on the Gastric test day. There was no significant difference in the satiety ratings. This study demonstrated that bypassing oro-pharyngeal and oesophageal exposure decreases the normal physiological CPR with detriment to IR and gastric emptying.

  17. How the impact of median neuropathy on sensorimotor control capability of hands for diabetes: an achievable assessment from functional perspectives.

    Haw-Yen Chiu

    Full Text Available To comprehend the sensorimotor control ability in diabetic hands, this study investigated the sensation, motor function and precision pinch performances derived from a pinch-holding-up activity (PHUA test of the hands of diabetic patients and healthy subjects. The precision, sensitivity and specificity of the PHUA test in the measurements of diabetic patients were also analyzed. We hypothesized that the diabetic hands would have impacts on the sensorimotor functions of the hand performances under functionally quantitative measurements. One hundred and fifty-nine patients with clinically defined diabetes mellitus (DM and 95 age- and gender-matched healthy controls were included. Semmes-Weinstein monofilament (SWM, static and moving two-point discrimination (S2PD and M2PD, maximal pinch strength and precision pinch performance tests were conducted to evaluate the sensation, motor and sensorimotor status of the recruited hands. The results showed that there were significant differences (all p<0.05 in SWM, S2PD, M2PD and maximum pinch strength between the DM and control groups. A higher force ratio in the DM patients than in the controls (p<0.001 revealed a poor ability of pinch force adjustment in the DM patients. The percentage of maximal pinch strength was also significantly different (p<0.001 between the DM and control groups. The sensitivity, specificity and area under the receiver operating characteristic curve were 0.85, 0.51, and 0.724, respectively, for the PHUA test. Statistically significant degradations in sensory and motor functions and sensorimotor control ability were observed in the hands of the diabetic patients. The PHUA test could be feasibly used as a clinical tool to determine the sensorimotor function of the hands of diabetic patients from a functional perspective.

    2012-01-01

    Full Text Available In order to apply sphere decoding algorithm in multiple-input multiple-output communication systems and to make it feasible for real-time applications, its computational complexity should be decreased. To achieve this goal, this paper provides some useful insights into the effect of initial and the final sphere radii and estimating them effortlessly. It also discusses practical ways of initiating the algorithm properly and terminating it before the normal end of the process as well as the cost of these methods. Besides, a novel algorithm is introduced which utilizes the presented techniques according to a threshold factor which is defined in terms of the number of transmit antennas and the noise variance. Simulation results show that the proposed algorithm offers a desirable performance and reasonable complexity satisfying practical constraints.

  20. City-specific vehicle emission control strategies to achieve stringent emission reduction targets in China's Yangtze River Delta region.

    Zhang, Shaojun; Wu, Ye; Zhao, Bin; Wu, Xiaomeng; Shu, Jiawei; Hao, Jiming

    2017-01-01

    The Yangtze River Delta (YRD) region is one of the most prosperous and densely populated regions in China and is facing tremendous pressure to mitigate vehicle emissions and improve air quality. Our assessment has revealed that mitigating vehicle emissions of NOx would be more difficult than reducing the emissions of other major vehicular pollutants (e.g., CO, HC and PM2.5) in the YRD region. Even in Shanghai, where the emission control implemented are more stringent than in Jiangsu and Zhejiang, we observed little to no reduction in NOx emissions from 2000 to 2010. Emission-reduction targets for HC, NOx and PM2.5 are determined using a response surface modeling tool for better air quality. We design city-specific emission control strategies for three vehicle-populated cities in the YRD region: Shanghai and Nanjing and Wuxi in Jiangsu. Our results indicate that even if stringent emission control consisting of the Euro 6/VI standards, the limitation of vehicle population and usage, and the scrappage of older vehicles is applied, Nanjing and Wuxi will not be able to meet the NOx emissions target by 2020. Therefore, additional control measures are proposed for Nanjing and Wuxi to further mitigate NOx emissions from heavy-duty diesel vehicles.

  2. On the electrostatic control achieved in transistors based on multilayered MoS2: A first-principles study

    Lu, Anh Khoa Augustin; Pourtois, Geoffrey; Luisier, Mathieu; Radu, Iuliana P.; Houssa, Michel

    2017-01-01

    In this work, the electrostatic control in metal-oxide-semiconductor field-effect transistors based on MoS2 is studied, with respect to the number of MoS2 layers in the channel and to the equivalent oxide thickness of the gate dielectric, using first-principles calculations combined with a quantum transport formalism. Our simulations show that a compromise exists between the drive current and the electrostatic control on the channel. When increasing the number of MoS2 layers, a degradation of the device performances in terms of subthreshold swing and OFF currents arises due to the screening of the MoS2 layers constituting the transistor channel.

    2016-11-24

    Viral hepatitis, especially those with parenteral and sexual transmission, still remain a major problem of public health, both globally and for the Republic of Moldova, due to wide spreading, endemicity, increased morbidity and mortality and high rate of invalidity following the chronization of infection, but usually neglected by population and public health authorities. This paper describes the epidemiology and preventive and control measures of hepatitis C in Moldova. Epidemiological analysis of the surveillance data on hepatitis C incidence in the Republic of Moldova was conducted. The data were obtained from the national reporting system of infectious diseases and serosurvey studies. Epidemiological particularities of acute and chronic hepatitis C in general Moldovan population and specific risk groups were evaluated. National hepatitis policies for prevention and control were analyzed. Only consolidation of all the actions stipulated in the national and international normative documents on the prevention and control of hepatitis, will help to reduce the morbidity of viral hepatitis C and probably to eliminate the new cases of disease in some regions.

    2013-01-01

    Ultra-definition, large-area displays with three-dimensional visual effects represent megatrend in the current/future display industry. On the hardware level, such a "dream" display requires faster pixel switching and higher driving current, which in turn necessitate thin-film transistors (TFTs) with high mobility. Amorphous oxide semiconductors (AOS) such as In-Ga-Zn-O are poised to enable such TFTs, but the trade-off between device performance and stability under illumination critically limits their usability, which is related to the hampered electron-hole recombination caused by the oxygen vacancies. Here we have improved the illumination stability by substituting oxygen with nitrogen in ZnO, which may deactivate oxygen vacancies by raising valence bands above the defect levels. Indeed, the stability under illumination and electrical bias is superior to that of previous AOS-based TFTs. By achieving both mobility and stability, it is highly expected that the present ZnON TFTs will be extensively deployed in next-generation flat-panel displays.

  7. THE EFFECT OF AN INTEGRATED AFFECTIVE-COGNITIVE TEACHING AND LEARNING APPROACH ON ACADEMIC ACHIEVEMENT, SELF-EFFICACY, LOCUS OF CONTROL AND ATTITUDE TOWARDS ENGINEERING

    Tahira Anwar Lashari

    2014-05-01

    Full Text Available Engineers are responsible for the sustainable development of society and to be effective in their role they must possess holistic skills that encompass the skills of the affective and the cognitive domain. Therefore, engineering education must place equal emphasis on the needs of the affective domain in addition to the needs of the cognitive domain. However, existing engineering education practices do not pay adequate attention to the needs of the affective domain. Therefore, the study seeks to determine the effect of a teaching and learning approach that integrates the affective and the cognitive learning needs on academic achievement, locus of control, self-efficacy, and attitude towards engineering. A quasi-experimental design study with pre and post-test was conducted on 70 engineering students who were enrolled in the Diploma of engineering programme in the Universiti Tun Hussein Onn Malaysia with n=36 and n=34 for the experimental and control group respectively. The results indicate that the experimental group was better on the achievement test and attitude measure compared to the control group and the academic improvement was most noticeable among the low achievers. In conclusion these results indicate that an integrated affective-cognitive learning approach can be used to induce simultaneous improvements in learning of the cognitive and affective domain.

    The aims of the project were to determine the glycaemic and insulin responses of non-insulin dependent diabetic patients (NIDDM) to 3 traditional Malaysian meals compared to oral glucose, and to determine whether guar gum would affect these responses. Patients with NIDDM were tested with 75 g oral glucose and three common breakfast meals of the three main ethnic groups of Malaysia. When compared with the oral glucose group, significantly by lower blood glucose responses were seen at 90 and 120 minutes post prandial for nasi lemak (pnasi lemak and between 15 and 30 minutes (p<0.03) for mee sup but not with roti telur. With addition of guar gum, there was no significant change of insulin responses with the three meals but a significant increase was seen at 30 minutes (p<0.02) after ingestion of glucose.

  9. Controlled Acoustic Bass System (CABS) A Method to Achieve Uniform Sound Field Distribution at Low Frequencies in Rectangular Rooms

    Celestinos, Adrian; Nielsen, Sofus Birkedal

    2008-01-01

    The sound field produced by loudspeakers at low frequencies in small- and medium-size rectangular listening rooms is highly nonuniform due to the multiple reflections and diffractions of sound on the walls and different objects in the room. A new method, called controlled acoustic bass system (CABS......), is introduced. The system utilizes front loudspeakers and extra loudspeakers on the opposite wall of the room processed to cancel out the rear-wall reflections, which effectively conveys a more uniform sound field. The system works in the time domain and presents good performance over the loudspeaker low...

    Full Text Available Reference panels from the 1000 Genomes (1000G Project Consortium provide near complete coverage of common and low-frequency genetic variation with minor allele frequency ≥0.5% across European ancestry populations. Within the European Network for Genetic and Genomic Epidemiology (ENGAGE Consortium, we have undertaken the first large-scale meta-analysis of genome-wide association studies (GWAS, supplemented by 1000G imputation, for four quantitative glycaemic and obesity-related traits, in up to 87,048 individuals of European ancestry. We identified two loci for body mass index (BMI at genome-wide significance, and two for fasting glucose (FG, none of which has been previously reported in larger meta-analysis efforts to combine GWAS of European ancestry. Through conditional analysis, we also detected multiple distinct signals of association mapping to established loci for waist-hip ratio adjusted for BMI (RSPO3 and FG (GCK and G6PC2. The index variant for one association signal at the G6PC2 locus is a low-frequency coding allele, H177Y, which has recently been demonstrated to have a functional role in glucose regulation. Fine-mapping analyses revealed that the non-coding variants most likely to drive association signals at established and novel loci were enriched for overlap with enhancer elements, which for FG mapped to promoter and transcription factor binding sites in pancreatic islets, in particular. Our study demonstrates that 1000G imputation and genetic fine-mapping of common and low-frequency variant association signals at GWAS loci, integrated with genomic annotation in relevant tissues, can provide insight into the functional and regulatory mechanisms through which their effects on glycaemic and obesity-related traits are mediated.

    Insulin resistance is common among children with overweight and obesity. However, knowledge about glucose fluctuations in these children is scarce. This study aims to evaluate glycaemic profiles in children with overweight and obesity in free-living conditions, and to examine the association between glycaemic profiles with insulin resistance and cardiovascular risk parameters. One hundred eleven children with overweight and obesity were included. 48-hour sensor glucose concentrations in free-living conditions, fasting plasma and post-glucose load concentrations, serum lipid and lipoprotein concentrations, homeostatic model assessment of insulin resistance (HOMA-IR), and blood pressure were evaluated. Hyperglycaemic glucose excursions (≥7.8 mmol/L) were observed in 25% (n = 28) of the children. The median sensor glucose concentration was 5.0 (2.7–7.3) mmol/L, and correlated with fasting plasma glucose concentrations (rs = 0.190, p = 0.046), serum insulin concentrations (rs = 0.218, p = 0.021), and HOMA-IR (rs = 0.230, p = 0.015). The hyperglycaemic area under the curve (AUC) correlated with waist circumference z-score (rs = 0.455, p = 0.025), triacylglycerol concentrations (rs = 0.425, p = 0.024), and HOMA-IR (rs = 0.616, p obesity in free-living conditions. Children with insulin resistance had higher median sensor glucose concentrations and a larger hyperglycaemic sensor glucose AUC, which are both associated with specific parameters predicting cardiovascular disease risk.

  12. Achieving the Health Care Financing Administration limits by quality improvement and quality control. A real-world example.

    Engebretson, M J; Cembrowski, G S

    1992-07-01

    With the enactment of the Clinical Laboratory Improvement Amendments of 1988 (CLIA 88), the federal government is now using proficiency testing as the primary indicator of laboratory quality. Laboratories with proficiency test failures are now at risk of a variety of harsh penalties including large monetary fines and suspension of operations. To minimize the risk of failed proficiency testing, we initiated a continuous quality improvement program in our general chemistry laboratory in conjunction with the use of a new survey-validated quality control product. This article describes the quality improvement program and our success in reducing the long-term random error in general chemistry. Despite our improvement program, significant analytical errors (greater than 30% of the CLIA limits) still exist in analytes measured by our chemistry analyzer. These errors are present in nearly the same analytes measured by other common chemistry analyzers indicating the need for improvement in their design and manufacture.

    Effective control of nano-scale biomolecules can enhance the sensitivity and limit of detection of an interdigitated microelectrode (IME) sensor. Manipulation of the biomolecules by dielectrophoresis (DEP), especially the negative DEP (nDEP) force, so that they are trapped between electrodes (sensing regions) was predicted to increase the binding efficiency of the antibody and target molecules, leading to a more effective reaction. To prove this concept, amyloid beta 42 (Aβ42) and prostate specific antigen (PSA) protein were respectively trapped between the sensing region owing to the nDEP force under 5V and 0.05V, which was verified with COMSOL simulation. Using the simulation value, the resistance change (ΔR/Rb) of the IME sensor from the specific antibody-antigen reaction of the two biomolecules and the change in fluorescence intensity were compared in the reference (pDEP) and nDEP conditions. The ΔR/Rb value improved by about 2-fold and 1.66-fold with nDEP compared to the reference condition with various protein concentrations, and these increases were confirmed with fluorescence imaging. Overall, nDEP enhanced the detection sensitivity for Aβ42 and PSA by 128% and 258%, respectively, and the limit of detection improved by up to 2-orders of magnitude. These results prove that DEP can improve the biosensor's performance.

    The purpose of the study was to assess the counselee participation in the follow-up visits, compared to the first visits, for breast cancer genetic counselling and to explore associations with counselees' achievement of their preferred role in decision making, information recall, knowledge, risk perception alignment and perceived personal control. First and follow-up visits for breast cancer genetic counselling of 96 counselees of a Dutch genetics center were videotaped (2008-2010). Counselees completed questionnaires before counselling (T1), after the follow-up visit (T2) and one year after the follow-up visit (T3). Consultations were rated with the Roter Interaction Analysis System (RIAS). Counselee participation was measured as the percentage of counselee utterances, the percentage of counselee questions and the interactivity (number of turns per minute). Follow-up visits had higher levels of counselee participation than first visits as assessed by the percentage of counselee talk, the interactivity and counselee questions. More counselee talk in the follow-up visit was related to higher achievement of the preferred role (T2) and higher perceived personal control (T3). Higher interactivity in the follow-up visit was related to lower achievement of the preferred role in decision making and lower information recall (T2). There were no significant associations with the percentage of questions asked and none of the participation measures was related to knowledge, risk perception alignment and perceived personal control (T2). In line with the interviewing admonishment 'talk less and listen more', the only assessment of counselee participation associated to better outcomes is the percentage of counselee talk. High interactivity might be associated with lower recall in breast cancer genetic counselees who are generally highly educated. However, this study was limited by a small sample size and a heterogeneous group of counselees. Research is needed on the interactions

    Full Text Available Aim: This study analyzed the metabolic effects of dietary advice to follow calorie-restricted low-glycaemic index diet with metformin in overweight / obese impaired glucose tolerance subjects. Methods: Sixteen subjects with body mass index between 27-38 kg/m² were followed monthly for 16 weeks and treated with metformin (1 g/day and dietary prescription for low-glycaemic index diet with energy reduction of 25-30% their total energy expenditure. Glucose metabolism, lipid profile, anthropometric and body composition, and food intake parameters were measured before and after the treatment. Paired t-tests/Wilcoxon tests were used to compare differences from baseline, with a statistical significance criterion of p < 0.05. Results: There were significant reductions in anthropometric and body composition parameters, decrease in HOMA2-%β and triglycerides concentrations, and increase in Cederholm index. These results show enhanced peripheral insulin sensitivity and preservation of pancreatic beta-cell function. Conclusion: Calorie-restricted low-glycaemic index diet and metformin was benefit to metabolic and anthropometric parameters in overweight/obese subjects with impaired glucose tolerance.

    Objective To evaluate long‐term outcomes in psoriatic arthritis (PsA) patients who achieved or did not achieve minimal disease activity (MDA) through 5 years of golimumab treatment in the GO‐REVEAL trial. Methods The GO‐REVEAL trial was a phase III, randomized, double‐blind trial with placebo‐control through week 24 followed by an open‐label extension of golimumab 50/100 mg treatment up to 5 years. In these post‐hoc analyses, MDA was defined by the presence of ≥5 of 7 PsA outcome measures (≤1 swollen joint, ≤1 tender joint, Psoriasis Area and Severity Index [PASI] ≤1, patient pain score ≤15, patient global disease activity score ≤20 [range 0–100], Health Assessment Questionnaire disability index [HAQ DI] ≤0.5, and ≤1 tender enthesis point). Results Treatment with golimumab yielded significantly higher MDA response rates versus patients randomized to placebo at week 14 (23.5% versus 1.0%; P golimumab‐treated patients overall. Irrespective of treatment randomization, achievement of MDA at ≥3 and ≥4 consecutive visits was associated with significantly less radiographic progression and more improvement in MDA components allowing specific assessment of physical function (HAQ DI) and overall disease activity (patient global assessment of disease activity) at week 256 versus patients not achieving MDA. Logistic regression analyses indicated that a 1‐unit higher baseline HAQ DI score yielded a significantly lower likelihood of achieving MDA at ≥3 (odds ratio 0.514 [95% confidence interval 0.321–0.824]; P = 0.006) and ≥4 (odds ratio 0.480 [95% confidence interval 0.290–0.795]; P = 0.004) consecutive visits. Conclusion Among golimumab‐treated PsA patients, better long‐term functional improvement, patient global assessment, and radiographic outcomes were observed when patients achieved persistent MDA.

    2017-01-01

    At the time of the Great East Japan earthquake and tsunami (March 2011), the authors developed a web-based information and communications technology (ICT)-based blood pressure (BP) monitoring system (the Disaster CArdiovascular Prevention [DCAP] Network) and introduced it in an area that was catastrophically damaged (Minamisanriku town) to help control the survivors' BP. Using this system, home BP (HBP) was monitored and the data were automatically transmitted to a central computer database and to the survivors' attending physicians. The study participants, 341 hypertensive patients, continued to use this system for 4 years after the disaster and all of the obtained HBP readings were analyzed. This DCAP HBP-guided approach helped achieve a decrease in the participants' HBPs (initial average: 151.3±20.0/86.9±10.2 mm Hg to 120.2±12.1/70.8±10.2 mm Hg) over the 4 years. In addition, the amplitude of seasonal BP variation was suppressed and the duration from the summer lowest HBP values to the winter peak HBP values was gradually prolonged. This ICT-based approach was useful to achieve strict HBP control and minimize the seasonal BP variation even in a catastrophically damaged area during a 4-year period after the disaster, suggesting that this approach could be a routine way to monitor BP in the community.

    2008-01-01

    Full Text Available A dry process induced phase transited, non disintegrating, controlled release, in situ formed asymmetric membrane capsular system for poorly water soluble drug, ketoprofen, was developed and evaluated both in vitro and in vivo for osmotic and controlled release of the drug. In situ formed asymmetric membrane capsules were prepared using fabricated glass capsule holders via dry, phase inversion process. Effect of varying osmotic pressure of the dissolution medium on drug release was studied. Membrane characterization by scanning electron microscopy showed an outer dense region with less pores and an inner porous region for the prepared asymmetric membrane. In vitro release studies and statistical test for all the prepared and marketed formulation were done at P > 0.05. The drug release was found to be independent of the pH, but dependent on the osmotic pressure of the dissolution medium. In vivo pharmacokinetic studies showed a level A correlation (R 2> 0.99 with 39.24 % relative bioavailability compared to immediate release tablet of ketoprofen. Excellent correlation achieved suggested that the in vivo performance of the phase transited in situ formed AMCs could be accurately predicted from their in vitro release profiles and could a means for controlled delivery of drugs with varying solubility.

    We present a temperature control method capable of effectively shortening the thermal cycling time of polymerase chain reaction (PCR) in a disposable polymer microfluidic device with an external heater and a temperature sensor. The method employs optimized temperature overshooting and undershooting steps to achieve a rapid ramping between the temperature steps for DNA denaturation, annealing and extension. The temperature dynamics within the microfluidic PCR chamber was characterized and the overshooting and undershooting parameters were optimized using the temperature-dependent fluorescence signal from Rhodamine B. The method was validated with the PCR amplification of mecA gene (162 bp) from methicillin-resistant Staphylococcus aureus bacterium (MRSA), where the time for 30 cycles was reduced from 50 min (without over- and undershooting) to 20 min.

    Kostense Piet J

    2009-06-01

    Full Text Available Abstract Background Many patients with type 2 diabetes (T2DM are not able to reach the glycaemic target level of HbA1c Methods/Design T2DM patients (n = 248, aged 35–75 years, with an HbA1c ≥ 7.0%, eligible for treatment with insulin and able to use the internet will be selected from general practices in two different regions in the Netherlands. Cluster randomisation will be performed at the level of general practices. Patients in the intervention group will use a self-developed internet programme to assist them in self-titrating insulin. The control group will receive usual care. Primary outcome is the difference in change in HbA1c between intervention and control group. Secondary outcome measures are quality of life, treatment satisfaction, diabetes self-efficacy and frequency of hypoglycaemic episodes. Results will be analysed according to the intention-to-treat principle. Discussion An internet intervention supporting self-titration of insulin therapy in T2DM patients is an innovative patient-centred intervention. The programme provides guided self-monitoring and evaluation of health and self-care behaviours through tailored feedback on input of glucose values. This is expected to result in a better performance of self-titration of insulin and consequently in the improvement of glycaemic control. The patient will be enabled to 'discover and use his or her own ability to gain mastery over his/her diabetes' and therefore patient empowerment will increase. Based on the self-regulation theory of Leventhal, we hypothesize that additional benefits will be achieved in terms of increases in treatment satisfaction, quality of life and self-efficacy.

    Full Text Available INTRODUCTION: Difficulties in word-level reading skills are prevalent in Brazilian schools and may deter children from gaining the knowledge obtained through reading and academic achievement. Music education has emerged as a potential method to improve reading skills because due to a common neurobiological substratum. OBJECTIVE: To evaluate the effectiveness of music education for the improvement of reading skills and academic achievement among children (eight to 10 years of age with reading difficulties. METHOD: 235 children with reading difficulties in 10 schools participated in a five-month, randomized clinical trial in cluster (RCT in an impoverished zone within the city of São Paulo to test the effects of music education intervention while assessing reading skills and academic achievement during the school year. Five schools were chosen randomly to incorporate music classes (n = 114, and five served as controls (n = 121. Two different methods of analysis were used to evaluate the effectiveness of the intervention: The standard method was intention-to-treat (ITT, and the other was the Complier Average Causal Effect (CACE estimation method, which took compliance status into account. RESULTS: The ITT analyses were not very promising; only one marginal effect existed for the rate of correct real words read per minute. Indeed, considering ITT, improvements were observed in the secondary outcomes (slope of Portuguese = 0.21 [p<0.001] and slope of math = 0.25 [p<0.001]. As for CACE estimation (i.e., complier children versus non-complier children, more promising effects were observed in terms of the rate of correct words read per minute [β = 13.98, p<0.001] and phonological awareness [β = 19.72, p<0.001] as well as secondary outcomes (academic achievement in Portuguese [β = 0.77, p<0.0001] and math [β = 0.49, p<0.001] throughout the school year. CONCLUSION: The results may be seen as promising, but they are not

    2014-06-01

    Full Text Available The optimum position of the optical window (OW of illuminated lateral double-drift region (DDR impact avalanche transit time (IMPATT device has been determined subject to achieve the finest optical control of both DC and RF properties of the device. The OW is a tiny hole that has to be created on the oxide layer through which the light energy of appropriate wavelength can be coupled to the space charge region of the device. A non-sinusoidal voltage is assumed to be applied across the diode and the corresponding terminal current response is obtained from a two-dimensional (2-D large-signal (L-S simulation technique developed by the authors for illuminated lateral DDR IMPATT diode. Both the DC and L-S properties of the illuminated device based on Si, designed to operate at W-band frequencies (75 – 110 GHz are obtained from the said L-S simulation. Simulation is carried out for different incident optical power levels of different wavelengths (600 – 1000 nm by varying the position of the fixed sized OW on the oxide layer along the direction of electrical conduction of the device. Results show that, the most favorable optical tuning can be achieved when the OW is entirely created over the p-type depletion layer, i.e. when the photocurrent is purely electron dominated. Also the 700 nm wavelength is found to be most suitable wavelength for obtaining the maximum optical modulation of both DC and RF properties of the device.

    Full Text Available BACKGROUND AND OBJECTIVES Stroke is a common cause of chronic debilitating disease as a result of the vascular related effect of certain part of the brain. Also the mortality due to the nature of stroke either Intracerebral Haemorrhage (ICH or Cerebral Infarction (Ischaemic stroke vary, the earlier causing more fatality. The risk factors of the ICH or the Ischaemic stroke vary to certain degree. Glycaemic state of stroke patients affects the outcome of them. It is of importance to establish clinical correlation of the glycaemic status of the stroke patients with the type and extent of the lesion documented by Computerised Tomography (CT scan of brain for development of preventive measures and clinical management of such patients for better outcome. Hence, this study was conducted among stroke patients who were admitted in Medicine wards, Jawaharlal Nehru Institute of Medical Sciences (JNIMS, Porompat, Manipur. DATA AND METHODS A study of stroke cases was undertaken in patients who were admitted to Medicine wards, Jawaharlal Nehru Institute of Medical Sciences (JNIMS, Porompat, Manipur from January 2011 till December 2014. All the patients were investigated with CT scan brain, Blood sugar along with Glycosylated Haemoglobin (HbA1C besides other routine tests and recorded. RESULT Out of the 200 stroke patients registered in 48 months, 120 patients were having hyperglycaemia. All the patients with stress hyperglycaemia were haemorrhagic. 85.71% of the cases among known diabetes were also haemorrhagic. CONCLUSION Glycaemic state of patients presented in stroke gives a picture of clinical difference. The size of the lesion measured by CT scan of brain also varies among different types of hyperglycaemia and the prognosis of the patients and showed that those patients with higher glucose level had haemorrhagic lesions with bigger size and had higher mortality rate. The deteriorating glucose tolerance with age also contributes to the increased incidence

    2014-09-01

    Nowadays, the use of enzymes has become a common practice in the bakery industry, as they can improve dough quality and texture of final product. However, the use of α-amylases could have a negative effect in the glycaemic load of product, due to the released sugars from the starch hydrolysis that are not used by yeasts during the fermentation process. This study evaluated the effect of the addition of α-amylase in bakery products with bran on in vitro kinetics of starch hydrolysis. The use of flour with a high degree of extraction or high bran amount could decrease the GI even with the inclusion of α-amylase in the formulation. It should be taken into account the amount of bran and α-amylase when formulating breads in order to obtain products with lower GI than white bread. However, the fact that kinetics of starch hydrolysis remained unaltered indicates that the use of α-amylase in bread-making processes could provide technological advantages improving quality of breads without markedly changes in their glycaemic index.

    A low glycaemic index (LGI) diet during pregnancy complicated by gestational diabetes mellitus (GDM) may offer benefits to the mother and infant pair beyond those during pregnancy. We aimed to investigate the effect of an LGI diet during pregnancy complicated with GDM on early post-natal outcomes. Fifty-eight women (age: 23-41 years; mean ± SD pre-pregnancy body mass index: 24.5 ± 5.6 kg m(-2) ) who had GDM and followed either an LGI diet (n = 33) or a conventional high-fibre diet (HF; n = 25) during pregnancy had a 75-g oral glucose tolerance test and blood lipid tests at 3 months post-partum. Anthropometric assessments were conducted for 55 mother-infant pairs. The glycaemic index of the antenatal diets differed modestly (mean ± SD: 46.8 ± 5.4 vs. 52.4 ± 4.4; P diet during pregnancy complicated by GDM has outcomes similar to those of a conventional healthy diet. Adequately powered studies should explore the potential beneficial effects of LGI diet on risk factors for chronic disease.

    There is currently an increased global interest in the published glycaemic index (GI) and glycaemic load (GL) values of foods. However, data on the GI and GL values of different varieties of foods within Côte d'Ivoire are very limited. The study therefore aimed at finding the GI and GL of the main food staples in Côte d'Ivoire. Following the International Standard Organisation's protocol (ISO/FDI 26642:2010), a selection of five staple foodstuffs were tested for their GI and GL. Fasted healthy subjects were given 50 g of available carbohydrate servings of a glucose reference, which was tested twice, and test foods which were tested once, on separate occasions. Excepted attieke (GI 63), the majority of foods tested have a high GI (GI>70). Attieke (agbodjama) had a high GL (GL 29) while placali (GL 17) and maize meal stiff porridge (GL 16) had medium GLs. The GLs of pounded cassava-plantain and pounded yam are 26 and 22. Consumption of attieke could minimize postprandial blood glucose spikes, in spite of high GL and potentially have benefit in the management and prevention of some chronic diseases.

  3. Challenges facing the elimination of sleeping sickness in west and central Africa: sustainable control of animal trypanosomiasis as an indispensable approach to achieve the goal.

    Simo, Gustave; Rayaisse, Jean Baptiste

    2015-12-16

    African trypanosomiases are infectious diseases caused by trypanosomes. African animal trypanosomiasis (AAT) remains an important threat for livestock production in some affected areas whereas human African trypanosomiasis (HAT) is targeted for elimination in 2020. In West and Central Africa, it has been shown that the parasites causing these diseases can coexist in the same tsetse fly or the same animal. In such complex settings, the control of these diseases must be put in the general context of trypanosomiasis control or "one health" concept where the coordination of control operations will be beneficial for both diseases. In this context, implementing control activities on AAT will help to sustain HAT control. It will also have a positive impact on animal health and economic development of the regions. The training of inhabitants on how to implement and sustain vector control tools will enable a long-term sustainability of control operations that will lead to the elimination of HAT and AAT.

    Reducing glycaemic index (GI) and glycaemic load (GL) inconsistently improves aspects of cognitive function and appetite in children. Whether altering the GL by lowering carbohydrate relative to protein and fat has a role in these effects is unknown. Therefore, we assessed the differential effects of beverages varying in GL and dairy composition on appetite, energy intake and cognitive function in children. A total of forty children (10–12 years) completed a double-blind, randomised, crossover trial, receiving three isoenergetic drinks (approximately 1100 kJ): a glucose beverage (GI 100, GL 65), a full milk beverage (GI 27, GL 5) and a half milk/glucose beverage (GI 84, GL 35). For 3 h post-consumption, subjective appetite and cognitive performance (speed of processing, memory, attention and perceptual speed) were measured hourly. At completion, each child was provided a buffet-style lunch and energy intake was calculated. Blood glucose was objectively measured using the Continuous Glucose Monitoring System. Blood glucose AUC values were significantly different between the drinks (P,0·001), but did not sustain above the baseline for 3 h for any drink. Mixed modelling revealed no effect of beverage on subjective appetite or energy intake. Participant sex and drink GL significantly interacted for short-term memory (P,0·001). When girls consumed either milk-containing beverage, they recalled 0·7–0·8 more words compared with 0·5 less words after the glucose drink (P#0·014). Altering GL of drinks by reducing carbohydrate and increasing protein did not affect appetite or cognition in children. Girls may demonstrate improved short-term memory after consuming beverages with higher protein and lower GL.

    2002-01-01

    This article examines one outcome of leadership: productive achievement. Without achievement one is judged to not truly be a leader. Thus, the ideal leader must be a visionary, a critical thinker, an expert, a communicator, a mentor, and an achiever of organizational goals. This article explores the organizational context that supports achievement, measures of quality nursing care, fiscal accountability, leadership development, rewards and punishments, and the educational content and teaching strategies to prepare graduates to be achievers.

    The concept of a technological quick fix or 'magic-bullet' for control and elimination of Neglected Tropical Diseases (NTDs) is flawed. NTDs are embedded within complex biological and social systems that are shaped by ecological and political contexts. This commentary emphasises the need for implementation research to address implementation gaps in the control of NTDs. With a specific focus on sub-Saharan Africa and helminth diseases amenable to preventive chemotherapy through mass drug administration, we explore the important role of context, programme partnerships and community in achieving equitable and effective NTD control.

    2012-05-15

    Aims and background. To describe feasibility, tolerability and clinical outcomes of stereotactic body radiation therapy (SBRT) in the treatment of adrenal metastases in 34 consecutive cancer patients. Material and methods. Between March 2004 and July 2010, a total of 34 consecutive patients, accounting for 36 adrenal metastatic lesions, were treated with SBRT. SBRT treatments were delivered by a Linac Varian 600 with microMLC (3DLine, Elekta, Stockholm, Sweden) and a Linac ELEKTA Precise (Elekta). All 34 patients were clinically and radiologically evaluated during and after completion of SBRT. Following outcomes were taken into account: best clinical response at any time, local control, time to systemic progression, time to local progression, overall survival and toxicity. Survival was estimated by the Kaplan-Meier method and factor potentially affecting outcomes were analyzed with Cox regression analysis. Results. Total RT doses ranged from 20 Gy in 4 fractions to 45 Gy in 18 fractions (median dose: 32 Gy; median number of fractions: 4). All doses were prescribed to the 95% isodose line. No cases of Grade {>=} 3 toxicity were recorded. At a median follow-up time of 41 months (range, 12-75) 22 patients were alive. Three of 28 lesions (11%) showed complete response, 13/28 (46%) partial response, 10/28 (36%) stable disease and 2/28 (7%) progressed in the treated area. Local failure was observed in 13 cases. Actuarial local control rates at one and two years were 66% and 32%, respectively. Median time to local progression was 19 months. Median survival was 22 months. Conclusion. SBRT in adrenal gland metastasis is feasible without significant acute and late toxicities, with a good rate of local control. New SBRT fractionation schemes and the possibility to combine new systemic approaches should be investigated in order to further increase local control and reduce systemic disease progression.

  17. Health and economic impact of combining metformin with nateglinide to achieve glycemic control: Comparison of the lifetime costs of complications in the U.K

    Salas Maribel

    2004-04-01

    Full Text Available Abstract Background To reduce the likelihood of complications in persons with type 2 diabetes, it is critical to control hyperglycaemia. Monotherapy with metformin or insulin secretagogues may fail to sustain control after an initial reduction in glycemic levels. Thus, combining metformin with other agents is frequently necessary. These analyses model the potential long-term economic and health impact of using combination therapy to improve glycemic control. Methods An existing model that simulates the long-term course of type 2 diabetes in relation to glycosylated haemoglobin (HbA1c and post-prandial glucose (PPG was used to compare the combination of nateglinide with metformin to monotherapy with metformin. Complication rates were estimated for major diabetes-related complications (macrovascular and microvascular based on existing epidemiologic studies and clinical trial data. Utilities and costs were estimated using data collected in the United Kingdom Prospective Diabetes Study (UKPDS. Survival, life years gained (LYG, quality-adjusted life years (QALY, complication rates and associated costs were estimated. Costs were discounted at 6% and benefits at 1.5% per year. Results Combination therapy was predicted to reduce complication rates and associated costs compared with metformin. Survival increased by 0.39 (0.32 discounted and QALY by 0.46 years (0.37 discounted implying costs of £6,772 per discounted LYG and £5,609 per discounted QALY. Sensitivity analyses showed the results to be consistent over broad ranges. Conclusion Although drug treatment costs are increased by combination therapy, this cost is expected to be partially offset by a reduction in the costs of treating long-term diabetes complications.

  18. Design and fabrication of a perpendicular magnetic tunnel junction based nonvolatile programmable switch achieving 40% less area using shared-control transistor structure.

    2014-05-07

    A compact nonvolatile programmable switch (NVPS) using 90 nm CMOS technology together with perpendicular magnetic tunnel junction (p-MTJ) devices is fabricated for zero-standby-power field-programmable gate array. Because routing information does not change once it is programmed into an NVPS, high-speed read and write accesses are not required and a write-control transistor can be shared among all the NVPSs, which greatly simplifies structure of the NVPS. In fact, the effective area of the proposed NVPS is reduced by 40% compared to that of a conventional MTJ-based NVPS. The instant on/off behavior without external nonvolatile memory access is also demonstrated using the fabricated test chip.

    Full Text Available Providing information is not enough to improve diabetic patient’s compliance and achieve goals of therapy. Patient’s good awareness as well as emotional and social supports from family and community may play an important role to improve their compliance and clinical outcomes. Therefore, diabetes support groups were developed and each support group consisted of two pharmacists, two nurses, diabetic patients and their family members. A total of 70 type 2 diabetic patient’s were enrolled and randomized into support group 1 and support group 2. Patients in the group 1 received information leaflets only, while patient in the group 2 received pharmacist counselling and information leaflets at each meeting. Patient’s awareness of diabetes and compliance with medications were assessed by a short questionnaire at baseline and final follow-up. Blood glucose and cholesterol levels were also evaluated in both groups. At the end of study, the overall patient’s awareness and compliance improved by 61.5%. The random and fasting blood glucose levels decreased over than 30% in the group 2 and around 14% in the group 1. This study reveals that collaboration between health care professionals and community in the diabetes support group might help diabetic patients to increase their knowledge and compliance with the diabetes therapy as well as glycaemic control.

    Mechanism of iBGP single best path propagation may prevent the router from acquiring diverse paths,which results in connection disruption and inter-domain churn in the scene of transient link.MP-RCP optimises the route control platform (RCP)to reduce the session numbers and configuration complexity,makes use of global visible routes to compute and disseminate multiple paths for each router.When a router detects the failure in best path,the router encapsulates the packets and forwards them to the backup path to avoid the connection disruption.MP-RCP also separates the failure detection and processing in order to prevent the frequent convergence triggered by transient failures,which reduces the inter-domain disturbance.It is proved through Abilene topology and the experiment of topology generation that the MP-RCP structure reduces the forwarding disruption and inter-domain churn effectively.%iBGP 传播单条最佳路径机制不能保证路由器获得多样性路径,造成链路瞬时故障场景下连接中断及域间扰动。MP-RCP(MultiPath Route Control Platform)优化路由控制平台RCP以降低会话数量及配置复杂性,利用全局可视路由对每台路由器计算、分发多路径。当路由器检测到最佳路径失效后,将报文封装转发到备份路径中避免连接中断;MP-RCP中将失效检测、处理进行分离以避免瞬时故障引起的频繁收敛,从而降低了域间扰动。通过使用Abilene拓扑以及生成拓扑的实验证明了MP-RCP结构能有效避免转发中断和域间扰动。

    Williamson Margaret

    2012-08-01

    Full Text Available Abstract Background Research literature consistently documents that scientifically based therapeutic recommendations are not always followed in the hospital or in the primary care setting. Currently, there is evidence that some general practitioners in Australia are not prescribing appropriately for patients diagnosed with 1 hypertension (HT and 2 chronic heart failure (CHF. The objectives of this study were to improve general practitioner’s drug treatment management of these patients through feedback on their own prescribing and small group discussions with peers and a trained group facilitator. The impact evaluation includes quantitative assessment of prescribing changes at 6, 9, 12 and 18 months after the intervention. Methods A pragmatic multi site cluster RCT began recruiting practices in October 2009 to evaluate the effects of a multi-faceted quality improvement (QI intervention on prescribing practice among Australian general practitioners (GP in relation to patients with CHF and HT. General practices were recruited nationally through General Practice Networks across Australia. Participating practices were randomly allocated to one of three groups: two groups received the QI intervention (the prescribing indicator feedback reports and small group discussion with each group undertaking the clinical topics (CHF and HT in reverse order to the other. The third group was waitlisted to receive the intervention 6 months later and acted as a “control” for the other two groups. De-identified data on practice, doctor and patient characteristics and their treatment for CHF and HT are extracted at six-monthly intervals before and after the intervention. Post-test comparisons will be conducted between the intervention and control arms using intention to treat analysis and models that account for clustering of practices in a Network and clustering of patients within practices and GPs.

    The objective of this study was to examine associations between the mindful parenting style of parents of adolescents (aged 12-18) with type 1 diabetes mellitus (T1DM), and the glycaemic control and quality of life (QoL) of the adolescents. Chronic health conditions, such as T1DM, that require...... demanding treatment regimens, can negatively impact adolescents' quality of life. Therefore, it is important to determine whether mindful parenting may have a positive impact in these adolescents. Age, sex and duration of T1DM were examined as potential moderators. Parents (N = 215) reported on their own...... be a factor in helping adolescents manage their T1DM. Mindful parenting intervention studies for parents of adolescents with T1DM are needed to examine the effects on adolescents' glycaemic control and their quality of life....

  4. Fatty acid as structure directing agent for controlled secondary growth of CoFe2O4 nanoparticles to achieve mesoscale assemblies: A facile approach for developing hierarchical structures

    Saikia, K.; Kaushik, S. D.; Sen, D.; Mazumder, S.; Deb, P.

    2016-08-01

    Mesoscale hierarchical assemblies have emerged out as a new class of structures between fine dimension nanoparticles and bulk structures, having distinctly different physical properties from either side. Controlling the self-assembly process of primary nanoparticles and subsequent secondary growth mechanism is the key aspect for achieving such ordered structures. In this work, we introduce a new insight on achieving hierarchical assemblies of CoFe2O4 nanoparticles based on the temporal stability of the primary nanoparticles, where, the growth and stability of the primary particles are controlled by using oleic acid. It is found that the developed particles, at a critical concentration of oleic acid, prefer a secondary growth process, rather than promoting their individual growth. Domination of the attractive hydrophobic interaction over steric repulsion among the primary particles at this critical concentration of oleic acid is found to be the key factor for the initial aggregation of the primary particles, which eventually leads to the formation of spherical hierarchical assemblies via oriented attachment. It is also realized that the extremely well or poor stability conditions of the primary particles do not allow this secondary growth process. Estimated values of Co2+ distribution factor show that the cation distribution factor of CoFe2O4 system is not affected by the nature of dominant growth processes, when these are controlled. Interestingly, magnetic measurements reflect the stronger interparticle interaction in the hierarchical system and high magnetic moment values at low magnetic field.

  6. Closing the achievement gap through modification of neurocognitive and neuroendocrine function: results from a cluster randomized controlled trial of an innovative approach to the education of children in kindergarten.

    Clancy Blair

    Full Text Available Effective early education is essential for academic achievement and positive life outcomes, particularly for children in poverty. Advances in neuroscience suggest that a focus on self-regulation in education can enhance children's engagement in learning and establish beneficial academic trajectories in the early elementary grades. Here, we experimentally evaluate an innovative approach to the education of children in kindergarten that embeds support for self-regulation, particularly executive functions, into literacy, mathematics, and science learning activities. Results from a cluster randomized controlled trial involving 29 schools, 79 classrooms, and 759 children indicated positive effects on executive functions, reasoning ability, the control of attention, and levels of salivary cortisol and alpha amylase. Results also demonstrated improvements in reading, vocabulary, and mathematics at the end of kindergarten that increased into the first grade. A number of effects were specific to high-poverty schools, suggesting that a focus on executive functions and associated aspects of self-regulation in early elementary education holds promise for closing the achievement gap.

    The metabolic and performance benefits of prior consumption of low-glycaemic index (GI) meals v. high-GI meals were determined in extended high-intensity intermittent exercise. Participants (ten males and four females, aged 25·8 (sd 7·3) years) completed two testing days (each consisting of back-to-back 90-min intermittent high-intensity treadmill running protocols separated by 3 h) spaced by at least 7 d. Using a randomised counterbalanced cross-over design, low-GI, lentil-based meals (GI about 42) or high-GI, potato-based meals (GI about 78) matched for energy value were consumed 2 h before, and within 1 h after, the first exercise session. Performance was measured by the distance covered during five 1-min sprints (separated by 2·5 min walking) at the end of each exercise session. Peak postprandial blood glucose was higher by 30·8 % in the high-GI trial compared with the low-GI trial, as was insulin (P = 0·039 and P = 0·003, respectively). Carbohydrate oxidation was lower by 5·5 % during the low-GI trials compared with the high-GI trials at the start of the first exercise session (P exercise session during the high-GI trial compared with the low-GI trial. Sprint distance was not significantly different between conditions. A low-GI meal improved the metabolic profile before and during extended high-intensity intermittent exercise, but did not affect performance. Improvements in metabolic responses when consuming low-GI meals before exercise may be beneficial to the long-term health of athletes.

    2014-01-01

    Full Text Available Following an application from Beneo-Orafti SA, Sensus BV and Cosucra-Groupe Warcoing SA, submitted for authorisation of a health claim pursuant to Article 13(5 of Regulation (EC No 1924/2006 via the Competent Authority of Belgium, the EFSA Panel on Dietetic Products, Nutrition and Allergies (NDA was asked to deliver an opinion on the scientific substantiation of a health claim related to fructo-oligosaccharides (FOS from inulin and a reduction of post-prandial glycaemic responses. Non-digestible carbohydrates including FOS are resistant to hydrolysis and absorption in the small intestine and do not contribute to post-prandial glycaemia. This opinion applies to non-digestible carbohydrates (e.g. non-starch polysaccharides, resistant oligosaccharides and resistant starch which should replace sugars in foods or beverages in order to obtain the claimed effect. The Panel considers that the food constituent, non-digestible carbohydrates, which is the subject of the health claim, and the food constituent (i.e. sugars that non-digestible carbohydrates should replace in foods or beverages, are both sufficiently characterised in relation to the claimed effect. The Panel considers that a reduction of post-prandial glycaemic responses might be a beneficial physiological effect. In weighing the evidence, the Panel took into account that consumption of non-digestible carbohydrates results in reduced post-prandial blood glucose (and insulinaemic responses compared with the consumption of sugars on a weight-by-weight basis owing to the non-digestibility in the small intestine and to a decrease in the amount of available carbohydrates, and that the consumption of foods/drinks in which non-digestible carbohydrates replaced sugars induced lower post-prandial glycaemic and insulinaemic responses than sugar-containing foods/drinks.

  1. Achieving form in autobiography

    Nicholas (Nick Meihuizen

    2014-06-01

    Full Text Available This article argues that, unlike biographies which tend to follow patterns based on conventional expectations, salient autobiographies achieve forms unique to themselves. The article draws on ideas from contemporary formalists such as Peter McDonald and Angela Leighton but also considers ideas on significant form stemming from earlier writers and critics such as P.N. Furbank and Willa Cather. In extracting from these writers the elements of what they consider comprise achieved form, the article does not seek to provide a rigid means of objectively testing the formal attributes of a piece of writing. It rather offers qualitative reminders of the need to be alert to the importance of form, even if the precise nature of this importance is not possible to define. Form is involved in meaning, and this continuously opens up possibilities regarding the reader’s relationship with the work in question. French genetic critic Debray Genette distinguishes between ‘semantic effect’ (the direct telling involved in writing and ‘semiological effect’ (the indirect signification involved. It is the latter, the article argues in summation, which gives a work its singular nature, producing a form that is not predictable but suggestive, imaginative.

    Neuropathy is frequently a late complication of diabetes mellitus. Auditory neuropathy and microangiopathy of inner ear are the possible causes of hearing loss in diabetics. To study the correlation between glycaemic control and hearing threshold in patients with type 2 diabetes mellitus and to determine the differences of hearing threshold between groups treated with different modality. This single blind randomized controlled study was performed at the Department of Medicine and Department of Otorhinolaryngology, Hospital Universiti Kebangsaan Malaysia (UKM) between 1st May 2003 and 31st September 2004. This study was approved by Research Ethics Committee (code number FF-137). Subjects were randomized into two groups. Group 1 were patients treated with conventional oral hypoglycemic agents. The patients in group 2 were those treated with insulin injection. The subjects were seen 4 weekly for 3 months. Audiometric test were performed in all subjects at each visit. Blood were taken for fasting blood glucose, Hb1Ac, and fructosamine at every visit to determine the glycaemic controls of the subject. They were 11 patients (22 ears) treated with oral hypoglycemic agents and 17 patients treated (34 ears) with subcutaneous insulin. There is no significant difference between mean pure tone threshold before and after treatment at all frequencies in both groups. There is also no significance different in fasting glucose level and fructosamine. However, there is significant difference HbA1c levels between the two groups after treatment (P < 0.05). This study has shown that glycaemic control does not have significant impact on hearing. The hearing threshold is neither affected by insulin treatment nor by the glycaemic control.

  5. Achieving diagnosis by consensus

    Kane, Bridget

    2009-08-01

    This paper provides an analysis of the collaborative work conducted at a multidisciplinary medical team meeting, where a patient’s definitive diagnosis is agreed, by consensus. The features that distinguish this process of diagnostic work by consensus are examined in depth. The current use of technology to support this collaborative activity is described, and experienced deficiencies are identified. Emphasis is placed on the visual and perceptual difficulty for individual specialities in making interpretations, and on how, through collaboration in discussion, definitive diagnosis is actually achieved. The challenge for providing adequate support for the multidisciplinary team at their meeting is outlined, given the multifaceted nature of the setting, i.e. patient management, educational, organizational and social functions, that need to be satisfied.

  6. Recognizing outstanding achievements

    Speiss, Fred

    One function of any professional society is to provide an objective, informed means for recognizing outstanding achievements in its field. In AGU's Ocean Sciences section we have a variety of means for carrying out this duty. They include recognition of outstanding student presentations at our meetings, dedication of special sessions, nomination of individuals to be fellows of the Union, invitations to present Sverdrup lectures, and recommendations for Macelwane Medals, the Ocean Sciences Award, and the Ewing Medal.Since the decision to bestow these awards requires initiative and judgement by members of our section in addition to a deserving individual, it seems appropriate to review the selection process for each and to urge you to identify those deserving of recognition.

  9. Achieving closure at Fernald

    Bradburne, John; Patton, Tisha C.

    2001-02-25

    When Fluor Fernald took over the management of the Fernald Environmental Management Project in 1992, the estimated closure date of the site was more than 25 years into the future. Fluor Fernald, in conjunction with DOE-Fernald, introduced the Accelerated Cleanup Plan, which was designed to substantially shorten that schedule and save taxpayers more than $3 billion. The management of Fluor Fernald believes there are three fundamental concerns that must be addressed by any contractor hoping to achieve closure of a site within the DOE complex. They are relationship management, resource management and contract management. Relationship management refers to the interaction between the site and local residents, regulators, union leadership, the workforce at large, the media, and any other interested stakeholder groups. Resource management is of course related to the effective administration of the site knowledge base and the skills of the workforce, the attraction and retention of qualified a nd competent technical personnel, and the best recognition and use of appropriate new technologies. Perhaps most importantly, resource management must also include a plan for survival in a flat-funding environment. Lastly, creative and disciplined contract management will be essential to effecting the closure of any DOE site. Fluor Fernald, together with DOE-Fernald, is breaking new ground in the closure arena, and ''business as usual'' has become a thing of the past. How Fluor Fernald has managed its work at the site over the last eight years, and how it will manage the new site closure contract in the future, will be an integral part of achieving successful closure at Fernald.

    2013-01-01

    Aims Canagliflozin is a sodium glucose co-transporter 2 inhibitor in development for type 2 diabetes mellitus (T2DM). The efficacy and safety of canagliflozin were evaluated in subjects with T2DM inadequately controlled with diet and exercise. Methods In this 26-week, randomized, double-blind, placebo-controlled, phase 3 trial, subjects (N = 584) received canagliflozin 100 or 300 mg or placebo once daily. Primary endpoint was the change from baseline in haemoglobin A1c (HbA1c) at week 26. Secondary endpoints included the proportion of subjects achieving HbA1c < 7.0%; change from baseline in fasting plasma glucose (FPG), 2-h postprandial glucose (PPG) and systolic blood pressure (BP); and percent change in body weight, high-density lipoprotein cholesterol (HDL-C) and triglycerides. Adverse events (AEs) were recorded throughout the study. Results At week 26, HbA1c was significantly reduced from baseline with canagliflozin 100 and 300 mg compared with placebo (−0.77, −1.03 and 0.14%, respectively; p < 0.001 for both). Both canagliflozin doses significantly decreased FPG, 2-h PPG, body weight and systolic BP (p < 0.001 for all), and increased HDL-C compared with placebo (p < 0.01 for both). Overall incidences of AEs were modestly higher with canagliflozin versus placebo; rates of serious AEs and AE-related discontinuations were low and similar across groups. Incidences of genital mycotic infections, urinary tract infections and osmotic diuresis-related AEs were higher with canagliflozin; these led to few discontinuations. The incidence of hypoglycaemia was low across groups. Conclusion Canagliflozin treatment improved glycaemic control, reduced body weight and was generally well tolerated in subjects with T2DM inadequately controlled with diet and exercise.

    Full Text Available Background & objectives: Bone marrow is a rich source of adult stem cells that can differentiate into various cell types. Administration of mesenchymal stem cells (MSCs in irradiated diabetic rat model has transiently shown to decrease blood glucose level. This study examines the effect of high dose and multiple injections of MSCs on glycemic profile, their localization and regeneration of islet in diabetic Wistar rat. Methods: The study was carried out in male Wistar rats categorized into three groups (n=6, in each group: Group 1 as control, group 2 streptozotocin (STZ (50 mg/kg induced diabetic group and group 3 experimental group; 5-bromo-2-deoxyuridine (BrdU labelled allogenic MSCs were injected in the non-irradiated diabetic rat of the experimental group through tail vein. The blood glucose profile was subsequently monitored at regular intervals. Rats were sacrificed on day 45 and pancreas was examined for localization of BrdU labelled stem cells by immunofluorescence and islet-neogenesis by immunohistochemistry . Results: There was a significant reduction in blood glucose level after administration of MSCs in the experimental group (P<0.001. The presence of BrdU labelled MSCs in islet suggested their localization in the pancreas. Co-expression of anti-BrdU and anti-insulin antibody indicated trans-differentiation / fusion into insulin producing cells evidenced by significant increase in total number of islet (P=0.004 and insulin positive cells ( P<0.0001 in experimental group. Interpretation & conclusions: Our results showed that the MSCs administration in non-irradiated diabetic Wistar rat reduced hyperglycaemia and was accompanied by increased islet-neogengesis, possibly through trans- differentiation/fusion.

    2017-01-01

    Introduction There are several randomised controlled trials (RCTs) that have already shown that metabolic/bariatric surgery achieves short-term and long-term glycaemic control while there are no level 1A of evidence data regarding the effects of surgery on the microvascular complications of type 2 diabetes mellitus (T2DM). Purpose The aim of this trial is to investigate the long-term efficacy and safety of the Roux-en-Y gastric bypass (RYGB) plus the best medical treatment (BMT) versus the BMT alone to improve microvascular outcomes in patients with T2DM with a body mass index (BMI) of 30–34.9 kg/m2. Methods and analysis This study design includes a unicentric randomised unblinded controlled trial. 100 patients (BMI from 30 to 34.9 kg/m2) will be randomly allocated to receive either RYGB plus BMT or BMT alone. The primary outcome is the change in the urine albumin-to-creatinine ratio (uACR) captured as the proportion of patients who achieved nephropathy remission (uACR<30 mg/g of albumin/mg of creatinine) in an isolated urine sample over 12, 24 and 60 months. Ethics and dissemination The study was approved by the local Institutional Review Board. This study represents the first RCT comparing RYGB plus BMT versus BMT alone for patients with T2DM with a BMI below 35 kg/m2. Trial registration number NCT01821508; Pre-results. PMID:28077412

  19. Vietnam: achievements and challenges.

    1999-01-01

    The Vietnamese Government's successful development of the National Population and Family Planning Program has contributed in raising people's awareness on population issues and changing their attitudes and behavior regarding fostering small families. It has also been found to be very effective in substantially decreasing fertility level. In addition, economic levels of many households have been greatly improved since the adoption of a renovation policy. The advancement of welfare accompanied by the provision of better basic social services, including health services, has boost people's health. Several factors behind the achievements of the National Population and Family Planning Program include: 1) Strengthening of the political commitment of national and local leaders; 2) Nationwide mobilization of mass organizations and NGOs; 3) A strong advocacy and information, education and communication program; 4) Provision of various kinds of contraceptives; 5) Effective management of the program by priority; and 6) Support of the international community. Despite such successes, Vietnam is facing a number of new issues such as enlargement of the work force, shifting migration patterns and accelerating urbanization, aging of population, and change of household structure. Nevertheless, the Government of Vietnam is preparing a New Population Strategy aimed to address these issues.

    2014-06-01

    Full Text Available Background: Diabetes is the most common pre-existing medical disorder seen in pregnancy. Between 2-5% of pregnancies are complicated by diabetes. 87.5% of these women have gestational diabetes, 7.5% have type 1 and 5% have type 2. The study was designed to know the relation of control of diabetes to neonatal outcome in terms of metabolic complications. Methods: Study was conducted in laboring women in government medical college hospital Kottayam. Selection criteria was based on oral GTT. Patients with multiple gestations, other medical disorders were excluded. All the patients were monitored with hourly RBS in active phase of labor. It was compared with cord levels of RBS, calcium, haematocrit and admission to SCNU. For data measured at normal level Chi square test was used to study the significance of difference between the groups. For statistically significant differences odds ratios were computed and 95% confidence limits are calculated. Whenever necessary for quantitative data t- test was used to study the difference in mean values. Results: All normal RBS had live births and all the intrauterine deaths were associated with maternal hyperglycaemia. Among the SCNU admission 87.5% had hyperglycaemia in mother. 33.3 % of abnormal RBS had admission to SCNU whereas only 3.4% of the normal RBS group had admission. The risk of SCNU admission is 14 times more among babies of mothers with abnormal maternal RBS. X2 = 16.188 P = 0.000. The correlation coefficient between maternal RBS and cord RBS is 0.35 indicating a negative relationship between maternal RBS and Cord RBS. The coefficient of determination (r2 is 12 indicates 12% of variation of RBS is explained by maternal RBS. The average RBs cord among mothers with abnormal maternal RBS is 58.4 and among mothers with normal RBS is 72.4 and the observed difference is statistically significant. Conclusions: Heart The study shows that tight regulation of maternal glucose levels during labor can reduce

  1. Independent Control of the Magnetization in Ferromagnetic La2/3Sr1/3MnO3/SrTiO3/LaCoO3 Heterostructures Achieved by Epitaxial Lattice Mismatch.

    Rivas-Murias, Beatriz; Lucas, Irene; Jiménez-Cavero, Pilar; Magén, César; Morellón, Luis; Rivadulla, Francisco

    2016-03-01

    We report the effect of interface symmetry-mismatch on the magnetic properties of LaCoO3 (LCO) thin films. Growing epitaxial LCO under tensile strain on top of cubic SrTiO3 (STO) produces a contraction along the c axis and a characteristic ferromagnetic response. However, we report here that ferromagnetism in LCO is completely suppressed when grown on top of a buffer layer of rhombohedral La2/3Sr1/3MnO3 (LSMO), in spite of identical in-plane and out-of-plane lattice deformation. This confirms that it is the lattice symmetry mismatch and not just the total strain, which determines the magnetism of LCO. On the basis of this control over the magnetic properties of LCO, we designed a multilayered structure to achieve independent rotation of the magnetization in ferromagnetic insulating LCO and half-metallic ferromagnet LSMO. This is an important step forward for the design of spin-filtering tunnel barriers based on LCO.

  2. Teacher Quality and Student Achievement

    Linda Darling-Hammond

    2000-01-01

    Full Text Available Using data from a 50-state survey of policies, state case study analyses, the 1993-94 Schools and Staffing Surveys (SASS, and the National Assessment of Educational Progress (NAEP, this study examines the ways in which teacher qualifications and other school inputs are related to student achievement across states. The findings of both the qualitative and quantitative analyses suggest that policy investments in the quality of teachers may be related to improvements in student performance. Quantitative analyses indicate that measures of teacher preparation and certification are by far the strongest correlates of student achievement in reading and mathematics, both before and after controlling for student poverty and language status. State policy surveys and case study data are used to evaluate policies that influence the overall level of teacher qualifications within and across states. This analysis suggests that policies adopted by states regarding teacher education, licensing, hiring, and professional development may make an important difference in the qualifications and capacities that teachers bring to their work. The implications for state efforts to enhance quality and equity in public education are discussed.

  4. A long-term experimental case study of the ecological effectiveness and cost effectiveness of invasive plant management in achieving conservation goals: bitou bush control in booderee national park in eastern australia.

    David B Lindenmayer

    Full Text Available Invasive plant management is often justified in terms of conservation goals, yet progress is rarely assessed against these broader goals, instead focussing on short-term reductions of the invader as a measure of success. Key questions commonly remain unanswered including whether invader removal reverses invader impacts and whether management itself has negative ecosystem impacts. We addressed these knowledge gaps using a seven year experimental investigation of Bitou Bush, Chrysanthemoides monilifera subsp. rotundata. Our case study took advantage of the realities of applied management interventions for Bitou Bush to assess whether it is a driver or passenger of environmental change, and quantified conservation benefits relative to management costs of different treatment regimes. Among treatments examined, spraying with herbicide followed by burning and subsequent re-spraying (spray-fire-spray proved the most effective for reducing the number of individuals and cover of Bitou Bush. Other treatment regimes (e.g. fire followed by spraying, or two fires in succession were less effective or even exacerbated Bitou Bush invasion. The spray-fire-spray regime did not increase susceptibility of treated areas to re-invasion by Bitou Bush or other exotic species. This regime significantly reduced plant species richness and cover, but these effects were short-lived. The spray-fire-spray regime was the most cost-effective approach to controlling a highly invasive species and facilitating restoration of native plant species richness to levels characteristic of uninvaded sites. We provide a decision tree to guide management, where recommended actions depend on the outcome of post-treatment monitoring and performance against objectives. Critical to success is avoiding partial treatments and treatment sequences that may exacerbate invasive species impacts. We also show the value of taking advantage of unplanned events, such as wildfires, to achieve management

    2014-01-01

    Diabetes mellitus is recognized an independent risk factor for coronary artery disease (CAD) and mortality. Clinical trials have shown that statins significantly reduce cardiovascular events in diabetic patients. However, residual cardiovascular risk persists despite the achievement of target low-density lipoprotein cholesterol (LDL-C) levels with statin. High-density lipoprotein cholesterol (HDL-C) is an established coronary risk factor that is independent of LDL-C levels. We evaluated the impact of HDL-C on long-term mortality in diabetic patients with stable CAD who achieved optimal LDL-C. We enrolled 438 consecutive diabetic patients who were scheduled for percutaneous coronary intervention between 2004 and 2007 at our institution. We identified 165 patients who achieved target LDL-C diabetic patients with low-HDL-C who achieved optimal LDL-C (6.9 vs 17.9 %, log-rank P = 0.030). Multivariate Cox regression analysis showed that HDL-C is significantly associated with clinical outcomes (adjusted hazard ratio for MACE 1.33, 95 % confidence interval 1.01-1.75, P = 0.042). Low HDL-C is a residual risk factor that is significantly associated with long-term clinical outcomes among diabetic patients with stable CAD who achieve optimal LDL-C levels.

  12. Code Compliant School Buildings Boost Student Achievement

    Ronald B. Lumpkin

    2014-11-01

    Full Text Available Much of the focus in the literature in raising student achievement has included parental involvement, principal leadership, quality of instruction, students’ socioeconomic status, curriculum, and use of technology. Limited empirical research relates the condition of the school building as a variable that affects student achievement. Furthermore, there is no research that has examined the impact of building codes on achievement outcomes in the state of Florida. This research determined whether academic achievement of 4th-, 8th-, 9th-, and 10th-grade students as measured by the mathematics and reading subtests of the Florida Comprehensive Achievement Test (FCAT increased in new school buildings compliant to the 2000 Florida State Requirements for Educational Facilities. A causal-comparative design determined whether the independent variables, old and new school building influenced student achievement as measured by students’ FCAT mathematics and reading subtest scores. The control group was two cohorts of 4th-, 8th-, 9th-, and 10th-grade students who attended school in old buildings. The experimental group was two cohorts of 4th-, 8th-, 9th-, and 10th-grade students who attended school in new buildings. Transition from an old school into a new school was the treatment. Two hypotheses were formulated for testing and the research question for the inquiry was whether the percentage of students passing the FCAT mathematics and reading subtests increases after transitioning from an old school building into a new 2000 UBC (Uniform Building Code compliant facility.

  14. Peer relationships and academic achievement

    Krnjajić Stevan B.

    2002-01-01

    Full Text Available After their childhood, when children begin to establish more intensive social contacts outside family, first of all, in school setting, their behavior i.e. their social, intellectual, moral and emotional development is more strongly affected by their peers. Consequently, the quality of peer relationships considerably affects the process of adaptation and academic achievement and their motivational and emotional attitude towards school respectively. Empirical findings showed that there is bi-directional influence between peer relationships and academic achievement. In other words, the quality of peer relationships affects academic achievement, and conversely, academic achievement affects the quality of peer relationships. For example, socially accepted children exhibiting prosocial, cooperative and responsible forms of behavior in school most frequently have high academic achievement. On the other hand, children rejected by their peers often have lower academic achievement and are a risk group tending to delinquency, absenteeism and drop out of school. Those behavioral and interpersonal forms of competence are frequently more reliable predictors of academic achievement than intellectual abilities are. Considering the fact that various patterns of peer interaction differently exert influence on students' academic behavior, the paper analyzed effects of (a social competence, (b social acceptance/rejection, (c child's friendships and (d prosocial behavior on academic achievement.

This randomised, double-blind, placebo-controlled, Phase 3 study evaluated the efficacy and safety of canagliflozin as an add-on to metformin plus sulphonylurea in patients with T2DM. Methods Patients (N = 469) received canagliflozin 100 or 300 mg or placebo once daily during a 26-week core period and a 26-week extension. Prespecified primary end-point was change in HbA1c at 26 weeks. Secondary end-points included change in HbA1c at week 52 as well as proportion of patients achieving HbA1c < 7.0%, change in fasting plasma glucose (FPG) and systolic blood pressure, and per cent change in body weight, high-density lipoprotein cholesterol, and triglycerides (weeks 26 and 52). Results HbA1c was significantly reduced with canagliflozin 100 and 300 mg vs. placebo at week 26 (–0.85%, –1.06%, and –0.13%; p < 0.001); these reductions were maintained at week 52 (–0.74%, –0.96%, and 0.01%). Both canagliflozin doses reduced FPG and body weight vs. placebo at week 26 (p < 0.001) and week 52. Overall adverse event (AE) rates were similar across groups over 52 weeks, with higher rates of genital mycotic infections and osmotic diuresis-related AEs seen with canagliflozin vs. placebo; these led to few discontinuations. Increased incidence of documented, but not severe, hypoglycaemia episodes was seen with canagliflozin vs. placebo. Conclusions Canagliflozin improved glycaemic control, reduced body weight, and was generally well tolerated in T2DM patients on metformin plus sulphonylurea over 52 weeks. PMID:24118688

    Full Text Available In this study, the effects of blended learning on the middle school students’ academic achievement level and product evaluation scores were investigated. Blended learning provides more effective learning outcome gains through enriching todays’ developing Web Technologies with learning environments. This study was carried out with a total of 53 students enrolled in the experimental group and control group in the 6th grade classrooms during the 2014/2015 school year in a middle school in southwest part of Turkey. The intervention lasted 7 weeks. During the seven weeks, the unit of “problem solving, computer programming and development of Software product”, covered in Educational technologies and Software course, is taught through blended learning environment. The experimental group was taught using blended learning environment which supported with enriched web technologies (such as video-conference, Learning Management System, Discussion blogs , etc.. Whereas the experimental group was given access to all these enriched contents that are presented to the control group only during the classroom environment through present teaching methods. The design of the study includes quantitative method. We collected quantitative data such as academic achievement test and product evaluation scale. Academic achievement test and product evaluation scale were used as quantitative data collection sources. Quantitative data was collected through the evaluation of students’ projects that they developed during the process of the study and the academic achievement tests. During the data analysis phase, independent t-test, frequency and ANOVA tests were used. As a result of this study, it is concluded that blended learning environment had generated a significant difference in students’ academic achievement on behalf of experimental group. Implications of the study for the educational environments were discussed.

  3. Quality of life and metabolic status in mildly depressed patients with type 2 diabetes treated with paroxetine: A double-blind randomised placebo controlled 6-month trial

    Wahlbeck Kristian

    2007-06-01

    Full Text Available Abstract Background Depression is prevalent in people with type 2 diabetes and affects both glycaemic control and overall quality of life. The aim of this investigator-initiated trial was to evaluate the effect of the antidepressant paroxetine on quality of life, metabolic control, and mental well-being in mildly depressed diabetics aged 50–70 years. Methods We randomised 49 mildly depressed primary care outpatients with non-optimally controlled diabetes to a 6-month double-blind treatment with either paroxetine 20 mg per day or matching placebo. Primary efficacy measurements were quality of life and glycaemic control. The primary global outcome of the study was defined as a 10 points improvement in the SF-36 quality of life score. The primary metabolic outcome of the study was defined as a 0.8%-units decrease in glycosylated haemoglobin A1c(GHbA1c. Psychiatric symptoms were assessed with the Hospital Anxiety and Depression Scale. Results Six patients withdrew their consent before starting medication and six dropped out later in the study. We performed analysis of covariance with the baseline value as a covariate. Quality of life and glycaemic control as well as symptoms of depression and anxiety improved in both groups over the 6-month study period. After three months of treatment we found a statistically significant difference between the two treatment groups in GHbA1c (mean difference = 0.59%-units, p = 0.018 and in SF-36 score (mean difference = 11.0 points, p = 0.039. However, at the end of the study, no statistically significant differences between the treatment groups were observed. No severe adverse events occurred. Conclusion This pragmatic study of primary care patients did not confirm earlier preliminary findings indicating a beneficial effect of paroxetine on glycaemic control. The study indicates that in pragmatic circumstances any possible benefit from administration of paroxetine in diabetic patients with sub

  4. Disciplinary climate and student achievement

    Sortkær, Bent; Reimer, David

    Disciplinary climate has emerged as one of the single most important factors related to student achievement. Using data from the OECD Programme for International Student Assessment (PISA) 2003 for Canada, Denmark, Finland, Iceland, Latvia and Norway we find a significant and nontrivial association...... between the perceived disciplinary climate in the classroom and students’ mathematics performance in Canada, Denmark and Norway. Furthermore we exploit country specific class-size rules in order to single out a subsample with classroom-level data (PISA is sampled by age and not by classes) and find...... that the estimates based on school-level data might underestimate the relationship between disciplinary climate and student achievement. Finally we find evidence for gender differences in the association between disciplinary climate and student achievement that can partly be explained by gender-specific perceptions...

  5. Mathematics Achievement by Immigrant Children

    Gary G. Huang

    2000-05-01

    Full Text Available In this study, I examined academic achievement of immigrant children in the United States, Canada, England, Australia, and New Zealand. Analyzing data from the Third International Mathematics and Science Study (TIMSS, I gauged the performance gaps relating to the generation of immigration and the home language background. I found immigrant children's math and science achievement to be lower than the others only in England, the U.S., and Canada. Non-English language background was found in each country to relate to poor math and science learning and this disadvantage was stronger among native-born children—presumably children of indigenous groups—than among immigrant children. I also examined the school variation in math performance gaps, using hierarchical linear modeling (HLM to each country's data. The patterns in which language- and generation-related math achievement gaps varied between schools are different in the five countries.

    Siegler, Robert S; Duncan, Greg J; Davis-Kean, Pamela E; Duckworth, Kathryn; Claessens, Amy; Engel, Mimi; Susperreguy, Maria Ines; Chen, Meichu

    2012-07-01

    Identifying the types of mathematics content knowledge that are most predictive of students' long-term learning is essential for improving both theories of mathematical development and mathematics education. To identify these types of knowledge, we examined long-term predictors of high school students' knowledge of algebra and overall mathematics achievement. Analyses of large, nationally representative, longitudinal data sets from the United States and the United Kingdom revealed that elementary school students' knowledge of fractions and of division uniquely predicts those students' knowledge of algebra and overall mathematics achievement in high school, 5 or 6 years later, even after statistically controlling for other types of mathematical knowledge, general intellectual ability, working memory, and family income and education. Implications of these findings for understanding and improving mathematics learning are discussed.

    The aim was to develop reliable materials high in resistance to hostile environments, greatly improved in their resistance to oxidation, abrasion, and corrosion at high temperatures. To achieve the goal, trace quantities of high melting point metals were implanted into the compound formed on the substrate surface or deep into the substrate material. This year's research and development is outlined below. Important technologies in the ion process involved materials which at high temperatures were very resistant to oxidation, abrasion, and corrosion. The high-temperature oxidation resistant material was studied for use with the automobile supercharger rotor. The study on the high-temperature abrasion resistant material involved Ti-N thin coatings: the optimization of coating conditions, slidability at room temperature, and slidability in a high-temperature atmosphere. As for the high-temperature corrosion resistant material, studies were made to use it for refuse-fueled power generation. The TiAl material was also studied: the effect of ion implantation on the improvement of its high-temperature oxidation resisting capability, analysis into oxidized alloy surface properties, ion implantation into complicatedly shaped items and the optimum material for them, and the surface treatment by ion beams for improving resistance to high-temperature corrosion.

  1. The incongruous achiever in adolescence.

    Kline, S A; Golombek, H

    1974-06-01

    The authors wished to study some of the internal psychological dynamics of achievement in a nonpatient identified high school population. Questionnaires were administered to the Grade 13 students and their parents in a large high school. A number of students whose achievement and educational plans were not congruous with their general background were selected for interview. The findings suggest that a wide variety of ages and developmental stages can be discerned as critical points in the development of a student's attitude toward higher education. These students have many values in common, and their values appear related to a positive or negative identification with parental values. The students themselves show a wide range of personality integration. They relate in a special way to a wide variety of teachers' personalities.

    A genome-wide polygenic score (GPS), derived from a 2013 genome-wide association study (N=127,000), explained 2% of the variance in total years of education (EduYears). In a follow-up study (N=329,000), a new EduYears GPS explains up to 4%. Here, we tested the association between this latest EduYears GPS and educational achievement scores at ages 7, 12 and 16 in an independent sample of 5825 UK individuals. We found that EduYears GPS explained greater amounts of variance in educational achievement over time, up to 9% at age 16, accounting for 15% of the heritable variance. This is the strongest GPS prediction to date for quantitative behavioral traits. Individuals in the highest and lowest GPS septiles differed by a whole school grade at age 16. Furthermore, EduYears GPS was associated with general cognitive ability (~3.5%) and family socioeconomic status (~7%). There was no evidence of an interaction between EduYears GPS and family socioeconomic status on educational achievement or on general cognitive ability. These results are a harbinger of future widespread use of GPS to predict genetic risk and resilience in the social and behavioral sciences. PMID:27431296

Land use planning is the means of “budget management” for land use pattern. The relationship between land use planning and land use pattern is that the former is the norm for the latter, and the latter must be according to the former. Seeing GDP gross of the top 10 provinces that the state-owned construction land were supplied for from 2009 to 2013, the arable land area in grain provinces was downward together. This situation inevitably will bring a certain impact on national food security, so it is very important and urgent for us to enhance the management and control over land use planning. The speciifc measures should be focused on the following: regarding the fundamental shift in the mode of land use as the focus of our efforts, working out special land use planning and detailed land-use planning, establishing and perfecting the legal system of land use planning, and building the supervision system to monitor the fundamental shift in the mode of land use.

In this paper, we first perform a selection of the best spectrally-efficient CPM modulations to be embedded into SC-CPM schemes. Then, we consider the pragmatic capacity (a.k.a. BICM capacity) of CPM modulations and optimize it through a careful design of the mapping between input bits and CPM waveforms. The so obtained schemes are cascaded with an outer serially-concatenated convolutional code to form a pragmatic coded-modulation system. The resulting schemes exhibit performance very close to the CPM capacity without requiring iterations between the outer decoder and the CPM demodulator. As a result, the receiver exhibits reduced complexity and increased flexibility due to the separation of the demodulation and decoding functions.

    Glycaemic control is an essential component in diabetes management. There is growing attention on the protective effects of social capital on health, where social capital comprises features of society that facilitate co-operation for mutual benefit. The aim of this study was to investigate its role as a social determinant of health in the glycaemic control of diabetes mellitus. A cross-sectional study was conducted in a diabetes care charity institute, Isfahan, Iran from July 2010 to September 2010. Based on the level of HbA1c, all patients were divided into two groups: HbA1c level ≤ 7 as controlled diabetes and HbA1c level > 7 as uncontrolled diabetes. Sixty patients were randomly selected from each group (controlled diabetes and uncontrolled diabetes) and all agreed to participate. Social capital was measured using the Integrated Questionnaire for the Measurement of Social Capital (SC-IQ). The mean age of participants in the controlled diabetes group was 51.3 (SD: 7.8) years and 50.1(SD: 7.2) in the uncontrolled group. The mean social capital score was 185.1 (CI 95% 181.4-188.6) in the controlled group and 175.4 (CI 95% 171.8-178.8) in the uncontrolled group. There was a significant negative correlation between empowerment and political action and trust and solidarity dimensions and the level of HbA1c. In multiple regression analysis, trust and solidarity and empowerment and political action were significant predictors of the HbA1c. The results of this study suggest that social participation, trust, and empowerment and political action may determine how effectively the patient's diabetes has been managed. This initial finding warrants subsequent experimental investigations designed to identify strategies that can be used to foster the creation of social capital to improve diabetes control.

    Full Text Available Pupils with cerebral palsy attend elementary education accordind to a regular and special teaching plan and program. Regular school curriculum was reformed in 1992, while special plan and program has not been changed and adapted according to pupil’s needs and capacities. Music is one of the best means of expressing oneself and plays a very important role in the development of every child, the child with cerebral palsy in particular.In order to test the possibility of pupils with cerebral palsy, with and without mental retardation, to apprehend the actual program content, we have conducted research on musical achievement of children with cerebral palsy. During 2007 a research was carried out, on the sample of 27 pupils with cerebral palsy and mild mental retardation who attended classes in the school “Miodrag Matikj”, and a sample of16 students with cerebral palsy without mental retardation who attended the school “Dr. Dragan Hercog” in Belgrade.Results of the research, as well as analysis of music curriculum content, indicated that the capacities of students with cerebral palsy to carry out the curriculum tasks require special approach and methodology. Therefore, we introduced some proposals to overcome the difficulties in fulfilling music curriculum demands of those pupils. We made special emphasis on the use of computer based Assistive technology which facilitates the whole process to a large extent.

    The literature has long pointed to heightened frequencies of learning disabilities (LD) within the population of law offenders; however, a systematic appraisal of these observations, careful estimation of these frequencies, and investigation of their correlates and causes have been lacking. Here we present data collected from all youth (1,337 unique admissions, mean age 14.81, 20.3% females) placed in detention in Connecticut (January 1, 2010-July 1, 2011). All youth completed a computerized educational screener designed to test a range of performance in reading (word and text levels) and mathematics. A subsample (n = 410) received the Wide Range Achievement Test, in addition to the educational screener. Quantitative (scale-based) and qualitative (grade-equivalence-based) indicators were then analyzed for both assessments. Results established the range of LD in this sample from 13% to 40%, averaging 24.9%. This work provides a systematic exploration of the type and severity of word and text reading and mathematics skill deficiencies among juvenile detainees and builds the foundation for subsequent efforts that may link these deficiencies to both more formal, structured, and variable definitions and classifications of LD, and to other types of disabilities (e.g., intellectual disability) and developmental disorders (e.g., ADHD) that need to be conducted in future research.

    Individuals with tetraplegia lack independent mobility, making them highly dependent on others to move from one place to another. Here, we describe how two macaques were able to use a wireless integrated system to control a robotic platform, over which they were sitting, to achieve independent mobility using the neuronal activity in their motor cortices. The activity of populations of single neurons was recorded using multiple electrode arrays implanted in the arm region of primary motor cortex, and decoded to achieve brain control of the platform. We found that free-running brain control of the platform (which was not equipped with any machine intelligence) was fast and accurate, resembling the performance achieved using joystick control. The decoding algorithms can be trained in the absence of joystick movements, as would be required for use by tetraplegic individuals, demonstrating that the non-human primate model is a good pre-clinical model for developing such a cortically-controlled movement prosthetic. Interestingly, we found that the response properties of some neurons differed greatly depending on the mode of control (joystick or brain control), suggesting different roles for these neurons in encoding movement intention and movement execution. These results demonstrate that independent mobility can be achieved without first training on prescribed motor movements, opening the door for the implementation of this technology in persons with tetraplegia.

  2. Achieving High-Frequency Optical Control of Synaptic Transmission

    2014-01-01

    The optogenetic tool channelrhodopsin-2 (ChR2) is widely used to excite neurons to study neural circuits. Previous optogenetic studies of synapses suggest that light-evoked synaptic responses often exhibit artificial synaptic depression, which has been attributed to either the inability of ChR2 to reliably fire presynaptic axons or to ChR2 elevating the probability of release by depolarizing presynaptic boutons. Here, we compare light-evoked and electrically evoked synaptic responses for high-frequency stimulation at three synapses in the mouse brain. At synapses from Purkinje cells to deep cerebellar nuclei neurons (PC→DCN), light- and electrically evoked synaptic currents were remarkably similar for ChR2 expressed transgenically or with adeno-associated virus (AAV) expression vectors. For hippocampal CA3→CA1 synapses, AAV expression vectors of serotype 1, 5, and 8 led to light-evoked synaptic currents that depressed much more than electrically evoked currents, even though ChR2 could fire axons reliably at up to 50 Hz. The disparity between optical and electrical stimulation was eliminated when ChR2 was expressed transgenically or with AAV9. For cerebellar granule cell to stellate cell (grc→SC) synapses, AAV1 also led to artificial synaptic depression and AAV9 provided superior performance. Artificial synaptic depression also occurred when stimulating over presynaptic boutons, rather than axons, at CA3→CA1 synapses, but not at PC→DCN synapses. These findings indicate that ChR2 expression methods and light stimulation techniques influence synaptic responses in a neuron-specific manner. They also identify pitfalls associated with using ChR2 to study synapses and suggest an approach that allows optogenetics to be applied in a manner that helps to avoid potential complications.

  3. Achieving monospermy or preventing polyspermy?

    Dale B

    2016-06-01

    Full Text Available Brian Dale Centre for Assisted Fertilization, Naples, Italy Abstract: Images of sea urchin oocytes with hundreds of spermatozoa attached to their surface have fascinated scientists for over a century and led to the idea that oocytes have evolved mechanisms to allow the penetration of one spermatozoon while repelling supernumerary spermatozoa. Popular texts have extrapolated this concept, to the mammals and amphibians, and in many cases to include all the Phyla. Here, it is argued that laboratory experiments, using sea urchin oocytes deprived of their extracellular coats and inseminated at high densities, are artifactual and that the experiments leading to the idea of a fast block to polyspermy are flawed. Under natural conditions, the number of spermatozoa at the site of fertilization is extremely low, compared with the numbers generated. The sperm:oocyte ratio is regulated first by dilution in externally fertilizing species and the female reproductive tract in those with internal fertilization, followed by a bottleneck created by the oocytes extracellular coats. In order to progress to the oocyte plasma membrane, the fertilizing spermatozoon must encounter and respond to a correct sequence of signals from the oocytes extracellular coats. Those that do not, are halted in their progression by defective signaling and fall to the wayside. Final success and entry is finely tuned by the spermatozoon anchoring to an actin-rich predetermined site on the plasma membrane. In this review, the variation in the form, function, and number of gametes produced across the animal kingdom and the many ways in which sperm–oocyte interactions are regulated to reduce numbers are discussed. Since in nature, final sperm:oocyte ratios approach unity it would appear that selective pressures have favored the achievement of monospermy, rather than the evolution of polyspermy preventing mechanisms. Keywords: monospermy, natural conditions, polyspermy, laboratory

  10. Direct and indirect influences of executive functions on mathematics achievement.

    Cragg, Lucy; Keeble, Sarah; Richardson, Sophie; Roome, Hannah E; Gilmore, Camilla

    2017-02-08

    Achievement in mathematics is predicted by an individual's domain-specific factual knowledge, procedural skill and conceptual understanding as well as domain-general executive function skills. In this study we investigated the extent to which executive function skills contribute to these three components of mathematical knowledge, whether this mediates the relationship between executive functions and overall mathematics achievement, and if these relationships change with age. Two hundred and ninety-three participants aged between 8 and 25years completed a large battery of mathematics and executive function tests. Domain-specific skills partially mediated the relationship between executive functions and mathematics achievement: Inhibitory control within the numerical domain was associated with factual knowledge and procedural skill, which in turn was associated with mathematical achievement. Working memory contributed to mathematics achievement indirectly through factual knowledge, procedural skill and, to a lesser extent, conceptual understanding. There remained a substantial direct pathway between working memory and mathematics achievement however, which may reflect the role of working memory in identifying and constructing problem representations. These relationships were remarkably stable from 8years through to young adulthood. Our findings help to refine existing multi-component frameworks of mathematics and understand the mechanisms by which executive functions support mathematics achievement.

    2015-08-01

    Full Text Available Multiple teaching methods are used by teachers in order to improve learning of students. The most popular is lecture method, while very effective is cooperative learning method. Later teaching method had been preferred for teaching science and languages as cited by previous research studies. However, in the subjects of social sciences and humanities, its importance cannot be ignored. Following study is an effort to determine effect of cooperative learning method on students’ achievement in subject of Education.  Qusi experimental design, with pre and post test of control and experimental group was used to achieve target of the study. Sample of the study consisted of 63 female students enrolled in grade 12 of a public college. An achievement test was used as a pre-test, the students were than divided in experimental and control groups. Multiple cooperative learning activities were performed with experimental group by using three common methods of cooperative learning i.e., STAD, TGT and Jigsaw II. The control group was taught by lecture method only. After 8 weeks a post test was administered on both experimental and control group in order to identify difference in achievement. The independent sample t-test was used to measure the mean scores difference between achievement scores of control and treatment groups on pretest.  The results showed that there was no significant difference between the two groups (p=.825 leading to assumption that both groups were on equal level of achievement before intervention.  Same test was applied to find out difference between two groups before and after intervention.  The results showed that there was a significant difference in scores of control and experimental group in post-test. In addition to this paired sample t-test was conducted to compare the effect of intervention on achievement scores of experimental group.  The results showed that there was significant difference between scores of experimental

  17. Stable Same-Sex Friendships with Higher Achieving Partners Promote Mathematical Reasoning in Lower Achieving Primary School Children

    DeLay, Dawn; Laursen, Brett; Kiuru, Noona; Poikkeus, Anna-Maija; Aunola, Kaisa; Nurmi, Jari-Erik

    2015-01-01

    This study is designed to investigate friend influence over mathematical reasoning in a sample of 374 children in 187 same-sex friend dyads (184 girls in 92 friendships; 190 boys in 95 friendships). Participants completed surveys that measured mathematical reasoning in the 3rd grade (approximately 9 years old) and one year later in the 4th grade (approximately 10 years old). Analyses designed for dyadic data (i.e., longitudinal Actor-Partner Interdependence Models) indicated that higher achieving friends influenced the mathematical reasoning of lower achieving friends, but not the reverse. Specifically, greater initial levels of mathematical reasoning among higher achieving partners in the 3rd grade predicted greater increases in mathematical reasoning from 3rd grade to 4th grade among lower achieving partners. These effects held after controlling for peer acceptance and rejection, task avoidance, interest in mathematics, maternal support for homework, parental education, length of the friendship, and friendship group norms on mathematical reasoning.

  18. Efficacy of nanoparticles in achieving hemostasis

    Schmitt, Carrie Catherine

    Uncontrollable hemorrhage is significant cause of preventable death in the military and civilian setting. Hemostatic wound dressings have been created in an attempt to rectify this problem, but none currently on the market are highly effective at controlling hemorrhage resulting in a need for an effective hemostatic wound dressing. This study investigated the effects of gold, silver, and silica nanoparticles on blood coagulation time in order to determine if nanoparticle incorporation into a hemostatic wound dressing would effectively achieve hemostasis. Gold, silver, and silica nanoparticles were experimented with two different ex vivo studies to determine their effects on coagulation. A modified Lee White Method and a rotational viscometer were utilized to assess the nanoparticles ability to clot blood. Results obtained from the modified Lee White Method proved inconsistent and inconclusive demonstrating a need for improved testing methods. Results acquired from viscometer testing demonstrated that silica was effective in decreasing coagulation time indicating its potential use as a hemostatic agent and its prospective incorporation into a hemostatic wound dressing.

  19. Students' Achievement and Homework Assignment Strategies

    Fernández-Alonso, Rubén; Álvarez-Díaz, Marcos; Suárez-Álvarez, Javier; Muñiz, José

    2017-01-01

    The optimum time students should spend on homework has been widely researched although the results are far from unanimous. The main objective of this research is to analyze how homework assignment strategies in schools affect students' academic performance and the differences in students' time spent on homework. Participants were a representative sample of Spanish adolescents (N = 26,543) with a mean age of 14.4 (±0.75), 49.7% girls. A test battery was used to measure academic performance in four subjects: Spanish, Mathematics, Science, and Citizenship. A questionnaire allowed the measurement of the indicators used for the description of homework and control variables. Two three-level hierarchical-linear models (student, school, autonomous community) were produced for each subject being evaluated. The relationship between academic results and homework time is negative at the individual level but positive at school level. An increase in the amount of homework a school assigns is associated with an increase in the differences in student time spent on homework. An optimum amount of homework is proposed which schools should assign to maximize gains in achievement for students overall.
