Due to the fact that type 1 diabetes mellitus is one of the most common chronic illnesses of childhood and adolescence, the coexistence of eating disorders (ED) and diabetes often affects adolescents and young adults. Since weight management during this state of development can be especially diff icult for those with type 1 diabetes, some diabetics may restrict or omit insulin, a condition known as diabulimia, as a form of weight control. It has been clearly shown that ED in type 1 diabetics are associated with impaired metabolic control, more frequent episodes of ketoacidosis and an earlier than expected onset of diabetes-related microvascular complications, particularly retinopathy. The management of these conditions requires a multidisciplinary team formed by an endocrinologist/diabetologist, a nurse educator, a nutritionist, a psychologist and, frequently, a psychiatrist. The treatment of type 1 diabetes patients with DEB and ED should have the following compo- nents: diabetes treatment, nutritional management and psychological therapy. A high index of suspicion of the presence of an eating disturbance, particularly among those patients with persistent poor metabolic control, repeated episodes of ketoacidosis and/or weight andshape concerns are recommended in the initial stage of diabetes treatment, especially in young women. Given the extent of the problem and the severe medical risk associated with it, more clinical and technological research aimed to improve its treatment is critical to the future health of this at-risk population.展开更多

Patients and Methods: A cross-sectional study was conducted on 440 diabetic patients referred to selected teaching hospitals affiliated to Tehran University of Medical Sciences (TUMS) during six months in 2013. A two section 40-items self-report Questionnaire with demographic variables (12 items) and Health-Promoting Behaviors scale (28 items) included exercise (7 items), risk reducing (7 items), life enjoyment (3 items), stress management (5 items), responsibility (3 items) and healthy eating (3 items) domains. Data was analyzed using SPSS software version 11.5. Level of significance was set at p 0.05 level. Results: Mean scores of total health promoting behaviors in participants were (55.88 ± 18.09) and in domains of exercise, risk reducing, life?enjoyment, stress management, responsibility and healthy eating were (8.2 ± 6.5), (12.2 ± 6.1), (7.8 ± 2.6), (12.3 ± 3.8), (3.3 ± 3.1) and (6.9 ± 2.8) respectively. Life enjoyment was emphasized as the most significant domain in health promoting behaviors scale (65 percent). Study results revealed that there was a significant association among total health promoting behavior and age (p = 0.01), occupation (p = 0.01), family income (p p = 0.01) and HbA1C(p < 0.001). Conclusion: Study findings revealed the necessity of tailoring specific intervention programs to promote exercise and responsibility domains posit.展开更多

There is still no cure for the disease, and therapeutic goals and guidelines are a challenge. Currently, despite T1 DM intensive management and technological interventions in therapy, the majority of pediatric patients do not achieve glycemic control goals. This leads to a potential prognosis of long term diabetic complications, nephrological, cardiac, ophthalmological and neurological. Unfortunately, the neurological manifestations, including neurocognitive and behavioral complications, may present soon after disease onset, during childhood and adolescence. These manifestations may be prominent, but at times subtle, thus they are often not reported by patients or physicians as related to the diabetes. Furthermore, the metabolic mechanism for such manifestations has been inconsistent and difficult to interpret in practical clinical care, as reported in several reviews on the topic of brain and T1 DM. However, new technological methods for brain assessment, as well as the introduction of continuous glucose monitoring, provide new insights and information regarding brain related manifestations and glycemic variability and control parameters, which may impact the clinical care of children and youth with T1 DM. This paper provides a comprehensive review of the most recently reported behavioral, cognitive domains, sleep related, electrophysiological, and structural alterations in children and adolescences from a novel point of view. The review focuses on reported impairments based on duration of T1 DM, its timeline, and modifiable disease related risk parameters. These findings are not without controversy, and limitations of data are presented in addition to recommendations for future research direction.展开更多

It is a major healthcare issue among the elderly. This study was to identify the association between the health promoting behaviors and the diabetic control of type 2 diabetes mellitus (T2DM) patients. Methods: Cross sectional and descriptive research designs were used in this study. Participants were enrolled from three medical centers in northern, central and southern Taiwan during August, 2010 and June, 2011. The instruments encompassed biochemical indicators, and the preliminary developed scale of diabetes mellitus and health promotion (DMHP). Results: A total of 323 participants with T2DM were included in this study. The results showed 1) a high percentage of the participants used cigarette smoking, alcohol drinking and betel nut chewing, which were not conducive to adopting health promoting behaviors;2) a high percentage of patients showed abnormal blood glucose, dyslipidemia, and elevated blood pressure;3) few of the participants practiced ideally health promoting behaviors;and 4) practicing health-promoting behavior was positively associated with fasting blood glucose (FBG) and HbA1c levels. Conclusions: Patients with higher health promotion scores had better diabetic control. Less physical activity was found among those addicted to cigarette, alcohol and betel nut consumption. The findings suggest that health care providers should assess health promoting behaviors first for each diabetic patient.展开更多

Compared to plate steel, pipes have harder physical properties and tend to be harder and showed greater permeability with decreasing inner diameter. We found that the maximum corrosion current density in the secondary active state, which is the starting point of secondary passivation, appeared in the polarization curve measurement in tap water. Similar to the Vickers hardness and the maximum current density in the secondary active state, the permeability tended to increase as the diameter decreased. This is thought to increase the amount of deformation-induced martensitic and increase corrosion susceptibility. The peak of the secondary active current density was clearly seen as the potential sweep speed was increased. In addition, potential sweep speed dependence was observed in the corrosion susceptibility evaluation of deformation-induced martensite. In comparison with acid treatment, the formation of deformation-induced martensite was considered to occur in the extreme surface layer. The maximum corrosion current density in the secondary active state is expected to be a new susceptibility evaluation method for evaluating the deformation-induced martensitic transformation.展开更多

The study used the Health Belief Model (HBM) in applied thematic analysis. It involved semi-structured focus groups with 20 patients (M = 49.95 years old, SD 6.7). Three themes formulated: poor diabetes knowledge, diabetes perceived as a life burden, and the factors affecting self-efficacy in practicing healthy lifestyle. The poor diabetes knowledge was due to traditional indigenous beliefs and low health literacy. The perception that diabetes is a life burden was related with physical and psychological condition. The factors affecting the self-efficacy were the perceived barriers and external influence. It is need to understand the traditional indigenous beliefs, burdens, and lacking internal intention as the modifying factors of health beliefs. This study suggests that the development of integrated health promotion of diabetes should consider the HBM’s modifying factors in rural areas.展开更多

It is proved that there exists a unique strong solution for the two-dimensional Cauchy problem established that the initial density and the initial temperature decay not extremely slow. Particularly, it is allowed to be arbitrarily large for the initial data and vacuum states for the initial density, even including the compact support. Moreover, when the density depends on the Korteweg term with the viscosity coefficient and capillary coefficient, we obtain a consistent priority estimate by the energy method, and extend the local strong solutions to the global strong solutions. Finally, when the pressure and external force are not affected, we deform the fluid models of Korteweg type, we can obtain the large time decay rates of the gradients of velocity, temperature and pressure.展开更多
