Camplain R, Teufel-Shone NI, Jiang L, Chang J, Manson SM. Change in physical activity, food choices and hemoglobin A1c among American Indians and Alaska Natives with type 2 diabetes. Prev Med Rep 2022; 29:101945. [PMID: 36161132 PMCID: PMC9502664 DOI: 10.1016/j.pmedr.2022.101945] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/07/2022] [Revised: 06/14/2022] [Accepted: 08/05/2022] [Indexed: 12/03/2022] Open
Abstract
At baseline, physically active participants with higher healthy food scores had lower HbA1c levels than non-active participants. Over the three-year period, women who increased physical activity and/or healthy food consumption had slightly decreased HbA1c. Changes in physical activity and HbA1c differed by gender.
The prevalence of diabetes among American Indian and Alaska Native (AI/AN) adults is the highest of all United States racial/ethnic groups. Health behaviors, including regular physical activity and healthy food choices, are important components in the management of diabetes. We estimated the cross-sectional association between physical activity and healthy food scores, separately, and combined (PAHF) with hemoglobin A1c (HbA1c) over three years of the Special Diabetes Program for Indians-Healthy Heart demonstration project (SDPI-HH) intervention. The relationship between physical activity and food choices was also examined. Among 3,039 SDPI-HH participants at baseline, those reporting being physically active and having high healthy food scores had statistically significant lower HbA1c (mean = 7.67 ± 2.01) compared to inactive participants with low healthy food scores (7.90 ± 1.92). Among the 1,150 SDPI-HH participants who attended the three-year follow-up visit, participants who increased physical activity, consumption of healthy foods, or both had a larger decrease in HbA1c (β = -0.29, P = 0.03) over the study period compared to participants with no improvement in physical activity or increase in consuming healthy foods. This association was statistically significant among women (β = -0.35, P = 0.04) but not among men (β = -0.08, P = 0.70). Our findings indicated that an increase in healthier behaviors, including physical activity and healthy food choices, was associated with a small improvement in HbA1c in the subset of women who participated in the SDPI-HH through the three-year follow up. Although the decrease in HbA1c was small, physical activity and healthy food choices are important behaviors to incorporate into everyday life among AI/AN adults, particularly those with diabetes.

Retrospective Evaluation on the Use of a New Polysaccharide Complex in Managing Paediatric Type 1 Diabetes with Metabolic Syndrome (MetS). Nutrients 2021; 13:nu13103517. [PMID: 34684518 PMCID: PMC8540288 DOI: 10.3390/nu13103517] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/19/2021] [Revised: 09/26/2021] [Accepted: 10/01/2021] [Indexed: 12/30/2022] Open
Abstract
Background: Children and adolescents affected by type 1 diabetes have an increased risk of being overweight or obese and of suffering from cardiometabolic symptoms. Aims: To retrospectively evaluate the effects of a new complex of polysaccharide macromolecules, Policaptil Gel Retard® (PGR), on auxological and metabolic parameters, glycaemic variability and control parameters in paediatric patients with type 1 diabetes and metabolic syndrome (MetS). Patients and Methods: Data for 27 paediatric patients with a diagnosis of type 1 diabetes in conjunction with obesity and MetS of at least 5 years’ standing were collected and retrospectively studied. Of these, 16 (median age 12.9, range 9.5–15.8 years) had been adjunctively treated with PGR and 11 (median age 12.6, range 9.4–15.6 years) had not been treated with PGR. Auxological, metabolic and glycaemic control and variability parameters and insulin dosing were compared after 6 months in the two groups. Results: PGR significantly reduced BMI standard deviation score (SDS) (p < 0.005), waist SDS (p < 0.005), HbA1c (p < 0.05) and daily mean insulin dose requirement (p < 0.005). A significant improvement was also observed in the metabolic and glycaemic variability parameters of mean daily blood glucose (BG) levels (p < 0.005), SD of daily BG levels (p < 0.0001), mean coefficient of variation (p < 0.05), LBGI (p < 0.0001), HBGI (p < 0.0001), J-index (p < 0.005), total cholesterol (p < 0.005), HDL-cholesterol (p < 0.005) and LDL-cholesterol (p < 0.005) and triglycerides (p < 0.05). Conclusions: PGR produces a good auxological and metabolic response in obese patients with MetS who are affected by type 1 diabetes. It led to a significant reduction in BMI SDS, waist SDS and an improvement in glucose control and variability as well as in other MetS parameters. The use of polysaccharide compounds, especially if associated with appropriate dietary changes, may help achieve treatment targets in type 1 diabetes and reduce the risk that patients develop metabolic syndrome.

Abstract
BACKGROUND Glucokinase (GK), a cytoplasmic enzyme catalyzes the metabolism of glucose to glucose- 6-phosphate with the help of ATP and aids in the controlling of blood glucose levels within the normal range in humans. In pancreatic β-cells, it plays a chief role by controlling the glucose-stimulated secretion of insulin and in liver hepatocyte cells, it controls the metabolism of carbohydrates. GK acts as a promising drug target for the pharmacological treatment of patients with type 2 diabetes mellitus (T2DM) as it plays an important role in the control of carbohydrate metabolism. METHODS Data used for this review was based on the search from several science databases as well as various patent databases. The main data search terms used were allosteric GK activators, diabetes mellitus, type 2 diabetes, glucokinase, glucokinase activators and human glucokinase. RESULTS This article discusses an overview of T2DM, the biology of GK, the role of GK in T2DM, recent updates in the development of small molecule GK activators reported in recent literature, mechanism of action of GK activators and their clinical status. CONCLUSION GK activators are the novel class of pharmacological agents that enhance the catalytic activity of GK enzyme and display their antihyperglycemic effects. Broad diversity of chemical entities including benzamide analogues, carboxamides, acrylamides, benzimidazoles, quinazolines, thiazoles, pyrimidines, pyridines, orotic acid amides, amino acid derivatives, amino phosphates and urea derivatives have been synthesized in past two decades as potent allosteric activators of GK. Presently, the pharmaceutical companies and researchers are focusing on the design and development of liver-selective GK activators for preventing the possible adverse effects associated with GK activators for the long-term treatment of T2DM.

Abstract
Nutrition, the process by which a body nourishes itself through the transformation of food into energy and body tissues, is the most important factor in health maintenance, response to injury or illness, short-term and long-term rehabilitation, and longevity. Most rehabilitation providers and the individuals they treat have limited training and knowledge on even the basics of nutrition. An appropriate diet for individuals who are either in a health maintenance or an active program of rehabilitation includes 1500 to 2500 calories per day delivered via a balanced range of foodstuffs, preferably in a whole-food, plant-based manner.

Abstract
OBJECTIVE To examine the association between food choice and distress in a large national sample of American Indians/Alaska Natives (AI/AN) with type 2 diabetes. DESIGN Participants completed a sociodemographic survey, an FFQ and the Kessler-6 Distress Scale. Foods were identified as 'healthy' or 'unhealthy' using a classification grounded in the health education provided by the programme case managers; healthy and unhealthy food scores were calculated using reported intake frequencies. Pearson's correlation coefficients for distress and food scores were calculated for all participants and by gender. Multiple linear regression models stratified by gender assessed the association between distress and food scores, controlling for sociodemographics and duration of type 2 diabetes. SETTING Rural AI reservations and AN villages. SUBJECTS AI/AN (n 2484) with type 2 diabetes. RESULTS Both males (34·9 %) and females (65·1 %) had higher healthy food scores than unhealthy scores. In bivariate analysis, distress level had a significant negative correlation with healthy food scores among female participants, but the association was not significant among males. Significant positive correlations between distress and unhealthy food scores were found in both genders. In the final multivariate models, healthy food scores were not significantly related to distress; however, unhealthy food scores showed significant positive relationships with distress for both genders (females: β=0·078, P=0·0007; males: β=0·139, P<0·0001). CONCLUSIONS Health professionals working with AI/AN diagnosed with type 2 diabetes should offer food choice strategies during difficult times and recognize that males may be more likely than females to select unhealthy foods when distressed.

Abstract
Brazil is expected to have 19.6 million patients with diabetes by the year 2030. A key concept in the treatment of type 2 diabetes mellitus (T2DM) is establishing individualized glycemic goals based on each patient's clinical characteristics, which impact the choice of antihyperglycemic therapy. Targets for glycemic control, including fasting blood glucose, postprandial blood glucose, and glycated hemoglobin (A1C), are often not reached solely with antihyperglycemic therapy, and insulin therapy is often required. Basal insulin is considered an initial strategy; however, premixed insulins are convenient and are equally or more effective, especially for patients who require both basal and prandial control but desire a more simplified strategy involving fewer daily injections than a basal-bolus regimen. Most physicians are reluctant to transition patients to insulin treatment due to inappropriate assumptions and insufficient information. We conducted a nonsystematic review in PubMed and identified the most relevant and recently published articles that compared the use of premixed insulin versus basal insulin analogues used alone or in combination with rapid-acting insulin analogues before meals in patients with T2DM. These studies suggest that premixed insulin analogues are equally or more effective in reducing A1C compared to basal insulin analogues alone in spite of the small increase in the risk of nonsevere hypoglycemic events and nonclinically significant weight gain. Premixed insulin analogues can be used in insulin-naïve patients, in patients already on basal insulin therapy, and those using basal-bolus therapy who are noncompliant with blood glucose self-monitoring and titration of multiple insulin doses. We additionally provide practical aspects related to titration for the specific premixed insulin analogue formulations commercially available in Brazil.

Abstract
For married patients, chronic illness management often includes involvement of their spouses. We examined expectations regarding spouse involvement in the health of a partner with type 2 diabetes (N = 139 couples) from the perspectives of the patient and spouse. Partners' dyadic expectations and spouses' gender were posited to moderate spouses' diet-related control and patients' diet adherence. Among male patients, when both partners shared an expectation for spouse involvement greater diet-related spouse control was associated with better diet adherence of patients. In contrast, when expectations for spouse involvement were not shared, greater spouse control by wives was associated with poorer diet adherence. Dyadic expectations for spouse involvement did not moderate the association between spouse control and diet adherence among female patients. Findings suggest that shared expectations for spouse involvement can facilitate spouses' attempts to improve patients' dietary adherence, especially among male patients and their wives.

Abstract
OBJECTIVES To measure the frequency of herbal medicine use among patients with diabetes mellitus in Palestine; to determine demographic characteristics that may increase the likelihood of Complementary and Alternative Medicine (CAM) use and to find out how benefits, if any, were perceived by patients. METHOD Cross-sectional survey of patients attending the outpatient diabetes departments at 7 Governmental Hospitals. The method was based on semi-structured questionnaires. RESULTS A total of 1883 patients with diabetes were interviewed. Of the participants, 51.9% (n = 977) reported taking herbs primarily bought from Palestine (98%) and used in crude form mainly as decoctions (44.1%). The five most common herbal products used were: Trigonella berythea (Fabaceae) (n = 191, 19.6%), Rosmarinus officinalis (Lamiaceae) (n = 132, 13.5%), Olea europaea (Oleaceae) (n = 131, 13.4%), Teucrium capitatum (Lamiaceae) (n = 111, 11.4%), and Cinnamomum zeylanicum (Lauraceae) (n = 105, 10.8%). Most CAM users were above 40 years old 79.6% (n = 778), predominantly female (53.2%) and residents of refugee camps and rural areas (59.3, and 53.5, respectively). The recommendations of a family member or friend was the main factor prompting the use of CAM (40.2 and 37.1%). Most CAM users (71.7%) were satisfied with the perceived effects. Interestingly, 68% of patients recruited in the study did not disclose CAM use to their physicians or pharmacists. CONCLUSION Use of herbal therapies in diabetes is highly prevalent in Palestine. More than 70% of those using CAM (977, 51.9%) reported positive benefits including a feeling of slowing down disease progression, symptom relief, disease resolution or a reduction in the side effects of allopathic medication. Use of CAM should be explored with patients before clinical decisions are made. There is a need for health education relating to herbal use in conjunction with conventional medicines in diabetes.

Abstract
Excess energy intake and positive energy balance are associated with the development of obesity and insulin resistance, which is a key feature underlying the pathophysiology of type 2 diabetes. It is possible that dietary macronutrient intake may also be important, in particular increased levels of sugar and fat. High-fat energy-dense diets contribute to energy excess and obesity. Fat type is also a factor, with evidence suggesting that saturated fat intake is linked to insulin resistance. However, controversy exists about the role of carbohydrate in the development of diabetes. Epidemiological studies suggest that the risk of diabetes is unrelated to the total amount of carbohydrate, but that fibre intake and glycaemic load are important. Common dietary advice for the prevention of diabetes often advocates complex carbohydrates and restriction of simple carbohydrates; however, sugars may not be the main contributor to glycaemic load. Evidence continues to emerge in relation to the influence of dietary sugars intake on insulin resistance. In broader dietary terms fruit and vegetable intake may influence insulin resistance, possibly related to increased intake of fibre and micronutrients or displacement of other food types. There is also considerable debate about the most effective diet and appropriate macronutrient composition to facilitate weight loss. Recent evidence suggests comparable effects of diets with varying macronutrient profiles on weight loss, which is predominantly related to energy restriction. However, based on the results of diabetes prevention trials focusing on lifestyle measures, evidence favours low-fat diets as the preferred approach for weight loss and diabetes prevention.

Abstract
A importância da terapia nutricional no tratamento do diabetes melito tem sido enfatizada desde os primórdios de seu conhecimento, quando era a única intervenção efetiva. No diabetes tipo 1, a dieta adequada é fundamental em conseqüência de sua conjugação com a utilização da insulina exógena. A ingestão energética adequada, para obtenção de peso normal mantém o anabolismo, assegurando crescimento e desenvolvimento, assim como diminui a resistência à insulina. O uso correto dos micro e macronutrientes é de fundamental importância. O conhecimento do metabolismo dos carboidratos e sua relação com a elevação glicêmica, em seus aspectos qualitativos e quantitativos é enfatizada por possibilitar um bom controle, principalmente no período pós-prandial. É comentada também a correta utilização de proteínas para prevenir ou tratar nefropatia e gorduras para evitar a dislipidemia, obesidade e doença cardiovascular. Sacarose e edulcorantes artificiais devem ser utilizados com critérios. A aderência ao tratamento, entretanto, é fundamental para obtenção das metas desejadas.

Abstract
Insulin resistance underlies type 2 diabetes, CVD and the metabolic syndrome, driven by changes in diet, lifestyle, energy over–consumption and obesity. Nutritional recommendations for insulin resistance remain an area of controversy, particularly the quantity and types of dietary carbohydrate. The present review gives an overview of insulin resistance, its relationship to impaired insulin secretion and the metabolic syndrome, research methodologies used to measure insulin action and the epidemiological and intervention studies on the relationship between dietary carbohydrate and insulin resistance. Epidemiological studies provide little evidence to suggest that total dietary carbohydrate predicts risk of type 2 diabetes, and high–carbohydrate, high–fibre diets with low–glycaemic index (GI) may even contribute to diabetes prevention. Despite inherent limitations associated with techniques used to measure insulin resistance and dietary assessment, most intervention studies reveal an increase in glucose tolerance or insulin sensitivity with high–carbohydrate, low–fat diets in non–diabetic and diabetic individuals. When energy is restricted the source or reduced content of carbohydrate does not appear to be as important as fat for body weight. Thus, low energy intake is key to weight loss and augmentation of insulin sensitivity. Given this, widespread adoption of popular low–carbohydrate high–fat diets highlights the necessity to evaluate dietary interventions regarding safety and metabolic effects. While current evidence supports FAO/WHO recommendations to maintain a high–carbohydrate diet with low–GI foods, the relationships between carbohydrate and insulin sensitivity remains an important research area. Emerging technologies should further enhance understanding of gene–diet interactions in insulin resistance, providing useful information for future nutrition policy decisions.

Abstract
AIMS The aims were to describe the food habits of adolescents with Type 1 diabetes (Type 1 DM) and to compare them with healthy control subjects; to describe the distribution of energy-providing nutrients in patients and compare it with current recommendations and previous reports; and finally, to investigate associations between dietary intake and glycaemic control. METHODS One hundred and seventy-four adolescents with Type 1 DM and 160 age- and sex-matched healthy control subjects completed a validated food frequency questionnaire, and 38 randomly chosen patients completed a prospective 4-day food record. RESULTS Patients ate more regularly, and more often ate fruit and fruit juice, potatoes and root vegetables, meat, fish, egg, offal and sugar-free sweets than control subjects. Control subjects more often ate ordinary sweets and snacks. Patients chose coarse rye bread and dairy products with less fat to a greater extent than control subjects. Patients were heavier than control subjects. The intake of saturated fat was higher in patients compared with recommendations and, for boys with diabetes, the intake of protein was higher than recommended. Patients with poorer glycaemic control ate vegetables, fruit and fish less often than patients with better control. CONCLUSIONS The food habits of adolescents with Type 1 DM were healthier than those of control subjects. The intake of energy-providing nutrients was in line with current recommendations and showed improvements compared with previous reports, with the exception of fibre intake. The association between dietary intake and glycaemic control needs further investigation in prospective studies.

Abstract
OBJECTIVES To evaluate the effect on overall and cardiovascular mortality of diet and physical activity amongst diabetic persons. DESIGN Population-based prospective investigation, from 1993 to mid-2004, in the Greek arm of the European Prospective Investigation into Cancer and Nutrition. SETTING Volunteers from the general adult Greek population. SUBJECTS From an original sample of 28 572 volunteers, 1013 were taking at enrolment drugs for diabetes mellitus, had no missing information on the study variables and no comorbidity. Diet was assessed at baseline through a validated questionnaire. Proportional hazards regression was used to assess the relation of dietary factors and physical activity with mortality. INTERVENTIONS None. MAIN OUTCOME MEASURES Mortality ratios overall and from cardiovascular causes. RESULTS During 4579 person-years, 80 deaths have occurred, 46 of which from cardiovascular causes. Physical activity was strongly inversely associated with mortality. Two nutritional variables were significantly associated with diabetic mortality, with hazard ratios for increases of daily intake by one standard deviation being 1.31 for eggs [95% confidence interval (95% CI) 1.07 to 1.60] and 1.82 for saturated lipids (95% CI, 1.14 to 2.90). These two associations were considerably stronger for cardiovascular mortality. Waist-to-height ratio was positively, whereas hip circumference inversely associated with mortality. No significant interactions with gender for any of the study variables were evident. DISCUSSION Amongst confirmed diabetic persons, increased physical activity is associated with significant reduction of mortality, whereas increased consumption of eggs and saturated fats is associated with significant increase of mortality. Monounsaturated lipids are preferable for diabetic persons.
