Disordered eating behaviors in type 1 diabetic patients

Patients with type 1 diabetes mellitus are at high risk for disordered eating behaviors (DEB). 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.

Determinants of Health-Promoting Behaviors among Type 2 Diabetic Patients: Voice of Iran

Introduction: The aim of this study was to determine Health-Promoting Behaviors among type 2 diabetic mellitus patients. 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.

Short and long term neuro-behavioral alterations in type 1 diabetes mellitus pediatric population

Type 1 diabetes mellitus(T1DM) is one of the most prevalent chronic conditions affecting individuals under the age of 18 years, with increasing incidence worldwide, especially among very young age groups, younger than 5. 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.

Health-promoting behavior is positively associated with diabetic control among type 2 diabetes patients

Background: The increasing prevalence of type 2 diabetes mellitus (T2DM) poses a major public health challenge throughout the world. 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.

Effect of Pipe Diameter on Electrochemical Behavior of Stainless Steel Type 304 Pipes in Tap Water

We investigated the effects of pipe diameter on the corrosion resistance of stainless steel type 304 pipes using electrochemical measurements. 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.

Qualitative Rural Indonesian Study of Diabetes Knowledge, Health Beliefs, and Behaviors in Type 2 Diabetes Patients

This study was aimed at understanding diabetes knowledge, health beliefs, and behaviors among type 2 diabetes patients in Balinese rural areas. 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.

Global Existence and Large Time Asymptotic Behavior of Strong Solution to the Cauchy Problem of 2D Density-Dependent Boussinesq Equations of Korteweg Type

In this paper, we study the Cauchy problem of the density-dependent Boussinesq equations of Korteweg type on the whole space with a vacuum. 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.

Treatment Interventions of Type 2 Diabetes: A Systematic Review

Objective: This study looks to review different methods of lifestyle changing interventions, examine and compare them to determine usefulness, efficiency, and outcome in regard to future ventures to help control the rise of this type 2 diabetes. Methods: Three systematic reviews were found and compared based on efficacy and key differences in their approach to the ever-growing problem of type 2 diabetes. Outcomes and intervention styles of the studies were noted and critiqued based on their statistical significance. Conclusion: The first study revealed that multiple behavior change techniques (BCTs) correlate with a reduction in weight and HbA1c, especially when they work synergistically alongside one another. The second study spoke of how community intervention had an inclusive quality about it, which allowed for population variability to not affect implementation. It also showed that small incremental changes were best when trying to establish a change long-term across a large population. Finally, the third study revealed that, as the participant got closer to maintaining a good physical activity regiment, their self-efficacy also increased. The attributes of these studies give evidence that interventions that use multiple approaches are most effective when looking to improve physical activity and diet in Type 2 diabetics.

土壤中微塑料:类型、载体效应、迁移行为和潜在风险综述

微塑料(microplastics,MPs)作为一种新兴污染物,广泛存在于土壤中,并不断迁移转化,对土壤生态系统和生物多样性产生潜在风险。为了全面评估土壤MPs的环境风险,加强MPs污染的风险管控,讨论了土壤环境中MPs的类型,系统阐述了土壤MPs的载体效应和迁移行为,并从微生物、植物、动物以及人类四个方面综述了土壤MPs的潜在风险。土壤中MPs并不是单独存在的,MPs的潜在风险一方面来自其本身(颗粒和添加剂)的生物毒性,另一方面是其对共存污染物(有机污染物、重金属和致病菌等)的载体效应。在非生物(淋溶、重力)和生物等作用下,土壤中的MPs时刻都在经历着复杂的迁移过程,从而加剧了其对土壤生态系统的影响。由于粒径小,MPs很容易进入食物链并层层传递,从而对不同营养级生物的正常生理活动产生不利影响,包括影响土壤动植物的新陈代谢,生长,发育和繁殖。此外,MPs不仅在环境中存在,而且也在人体中被发现。MPs可通过饮食、呼吸或皮肤接触等途径进入人体,从而对人体可能产生一系列不良反应。虽然目前仍没有足够的证据证明MPs对人体的直接危害,但其潜在风险仍不容忽视。探讨了土壤MPs污染治理的策略,并对未来土壤微塑料污染的研究方向和重点进行了展望。研究将有助于加深人们对土壤微塑料污染的认识,并为更好地开展微塑料的毒理效应研究和风险评估提供科学线索和理论参考。

层板销合木的界面滑移与木梁受弯性能

层板销合木(简称销合木)是一种由规格材通过销组合而成的新型结构用木材,与胶合木相比具有加工快捷、成本低且更加绿色环保等优点。为研究销合木梁的弯曲性能,设计了8组木梁的四点弯试验,试验参数包括销的种类(木销和竹销)、销间距(70、100和140 mm)和层板的数量(3、4和6层)。此外,为揭示层积材界面销连接抗剪性能对销合木梁受弯性能的贡献,开展了木销和竹销连接销合木推出试验研究。研究结果表明:与木销连接相比,竹销连接的抗滑移刚度更高且延性更好;销合木梁的受弯性能介于无销接叠合木梁和胶合木梁之间,其组合效率为0.11~0.15;随层板数量的增加,梁截面的增高使销合木梁的抗弯性能显著上升;减小销间距对销合木梁的抗弯承载力与刚度均有一定的提升作用。采用欧洲规范5中的γ法预测销合木梁的抗弯刚度时结果偏大,因此认为对销合木梁的抗弯刚度进行计算时须对销连接的滑移刚度进行折减。
