Abstract
As the world's population becomes increasingly urbanized, there is growing concern about the impact of urban environments on cardiovascular health. Urban residents are exposed to a variety of adverse environmental exposures throughout their lives, including air pollution, built environment, and lack of green space, which may contribute to the development of early cardiovascular disease and related risk factors. While epidemiological studies have examined the role of a few environmental factors with early cardiovascular disease, the relationship with the broader environment remains poorly defined. In this article, we provide a brief overview of studies that have examined the impact of the environment including the built physical environment, discuss current challenges in the field, and suggest potential directions for future research. Additionally, we highlight the clinical implications of these findings and propose multilevel interventions to promote cardiovascular health among children and young adults.

Abstract
OBJECTIVE This study aims to explore the role of leptin in the ventricular remodeling process and its mechanism in the diabetic rats' model. METHODS The diabetic SD rats model induced by streptozotocin was established. The SD rats were randomly divided into 4 groups: control group (20 rats treated with citric acid/sodium citrate buffer); M0 group (10 rats treated with physiological saline); M1 group (10 rats treated with 50 μg/kg LP); M2 group (10 rats treated with 100 μg/kg LP). Ang-II was detected by ELISA. The expression levels of LP and Ob-Rb were detected by RT-PCR. MAPK phosphorylation changes were detected by western blotting. Myocardial morphology was observed. RESULTS Compared with control group, the blood glucose concentration and Ang-II significantly increased in diabetic model groups (P < 0.01) and body weight decreased (P < 0.05). The expression levels of LP and Ob-Rb increased and heart function decreased in diabetic model groups. CONCLUSIONS LP may be involved in the myocardial cell hypertrophy through the neuroendocrine system and associated with the JAK-STAT, Ras-Raf-MEK-MAPK and PI-3K signaling pathway, which provides a new concept for the pathogenesis of cardiac hypertrophy.

Abstract
The prevalence of type 2 diabetes mellitus (T2DM) in youth has increased dramatically over the past decades. The literature also suggests that the progression from an impaired glucose tolerance state to established T2DM is more rapid in youth, compared to adults. The presence of significant cardiovascular complications in youth with T2DM, including cardiac, macrovascular, and microvascular remodeling, is another major issue in this younger cohort and poses a significant threat to the healthcare system. However, this issue is only now emerging as a major public health concern, with few data to support optimal treatment targets and strategies to reduce cardiovascular disease (CVD) risk in youth with T2DM. Accordingly, the purpose of this minireview is to better understand the cardiovascular complications in youth with T2DM. We briefly describe the pathophysiology from youth studies, including oxidative stress, inflammation, renin-angiotensin aldosterone system, and epigenetics, which link T2DM and CVD. We also describe the literature concerning the early signs of CVD in youth and potential treatment options to reduce cardiovascular risk.

Abstract
The epidemic of childhood obesity worldwide has led to increased incidence of the metabolic syndrome and type 2 diabetes in the pediatric and adolescent population. As such, there is increasing concern that this large population of children is at risk for the long-term complications of diabetes, specifically cardiovascular disease. With cardiovascular disease remaining the leading cause of death in adults, this presents a significant public health concern as these children age. In this article, we discuss cardiovascular disease and risk in children and adolescents with type 2 diabetes, including the epidemiology of type 2 diabetes, atherosclerotic cardiovascular disease, obesity, hypertension, and left ventricular function.

Abstract
Diabetes mellitus (DM) induces a large number of diseases of the nervous, cardiovascular, and some other systems of the organism. One of the main causes of the diseases is the changes in the functional activity of hormonal signaling systems which lead to the alterations and abnormalities of the cellular processes and contribute to triggering and developing many DM complications. The key role in the control of physiological and biochemical processes belongs to the adenylyl cyclase (AC) signaling system, sensitive to biogenic amines and polypeptide hormones. The review is devoted to the changes in the GPCR-G protein-AC system in the brain, heart, skeletal muscles, liver, and the adipose tissue in experimental and human DM of the types 1 and 2 and also to the role of the changes in AC signaling in the pathogenesis and etiology of DM and its complications. It is shown that the changes of the functional state of hormone-sensitive AC system are dependent to a large extent on the type and duration of DM and in experimental DM on the model of the disease. The degree of alterations and abnormalities of AC signaling pathways correlates very well with the severity of DM and its complications.
