Sphingolipid metabolism in type 2 diabetes and associated cardiovascular complications.

Sphingolipid metabolism in type 2 diabetes and associated cardiovascular complications. Exp Ther Med. 2019 Nov;18(5):3603-3614 Authors: Sui J, He M, Wang Y, Zhao X, He Y, Shi B Abstract Sphingolipid metabolism is dysregulated in type 2 diabetes mellitus (T2DM); however, the focus of previous studies was mostly limited to ceramide (Cer), and only few studies have investigated other metabolites, including sphingosine-1 phosphate (So1P). The present study aimed to examine the involvement of 8 major sphingolipid metabolites, including Cer, glucosyl ceramide (GluCer), lactosyl ceramide (LacCer), sphingomyelin (SM), sphinganine (Sa), So1P, sphingosine (So) and sphinganine-1-phosphate (Sa1P), during the progression of T2DM, and to evaluate the ability of serum sphingolipids to predict cases of diabetes with an elevated risk of cardiovascular complications. Blood samples were obtained from 245 participants who were divided into 3 groups: Healthy controls, pre-diabetes (pre-DM) and diagnosed diabetes. The 8 major sphingolipid metabolites were measured by high-performance liquid chromatography-tandem mass spectrometry and blood parameters were determined by routine laboratory assays for all subjects. Among the sphingolipid metabolites, So1P was associated with sex and lean mass index, but not with the body mass index. So1P was highest in healthy controls and gradually decreased when the disease proceeded to pre-DM and T2DM. GluCer, SM, Sa and So decreased in pre-DM...

ElshazlyAbstractPeroxisome proliferator-activated receptor γ (PPAR-γ) agonist, pioglitazone, is used clinically to improve the glycemic state in patients with type-2 diabetes mellitus. Independent of its blood glucose-lowering properties, pioglitazone ameliorates different cardiovascular disorders. The aim of the present study was to investigate the effect of pioglitazone on cardiovascular complications of N-nitro-L-arginine methyl ester (L-NAME)-induced hypertensi...

Authors: Takahashi T, Matsuura C, Toyoda K, Suzuki Y, Yamada N, Kobayashi A, Sugai S, Shimoi K Abstract In order to estimate the potential risk of chemicals including drug in patients with type 2 diabetes mellitus (T2DM), we investigated allyl alcohol induced liver injury using SD rats and Spontaneously Diabetic Torii-Leprfa (SDT fatty) rats as a model for human T2DM. The diabetic state is one of the risk factors for chemically induced liver injury because of lower levels of glutathione for detoxification by conjugation with chemicals and environmental pollutants and their reactive metabolites. Allyl alcohol is met...

ConclusionLV mass and diastolic function were not affected after 1  year of metformin treatment in patients with T2DM. However, we observed benefits in terms of reductions in both BMI and LDL-C levels and preservation of renal function.Trial RegistrationUMIN000006504. Registered 7 October 2011.

Conclusion: The study shows that nearly half of the T2DM patients that exhibited low level of functional health literacy had low diabetes self-management.  Our findings also show that gender significantly affects diabetes self-management in which odds are a lot higher among females than males with diabetes self-management. This study underscores the importance of proper counselling and education about diabetes control on both patients and family members. PMID: 31707414 [PubMed - in process]

Allostasis and allostatic load are new concepts explaining the changes in body stemming from chronic stress. These concepts are explained with the assessment of metabolic, cardiovascular, inflammatory, and neuroendocrine systems. Type 2 Diabetes Mellitus (DM) is a chronic disease with the fluctuations in fasting plasma glucose, and also in other various biomarkers and poses a risk forother chronic diseases. The course and duration of the disease, genetic factors, and environmental factors, including nutrition, aggravate these complications. Allostatic load is a multi-system assessment. Individuals’ compliance with th...

AbstractThe accurate 3D reconstruction of organs from radiological scans is an essential tool in computer-aided diagnosis (CADx) and plays a critical role in clinical, biomedical and forensic science research. The structure and shape of the organ, combined with morphological measurements such as volume and curvature, can provide significant guidance towards establishing progression or severity of a condition, and thus support improved diagnosis and therapy planning. Furthermore, the classification and stratification of organ abnormalities aim to explore and investigate organ deformations following injury, trauma and illnes...

AbstractPurposeTo investigate the accuracy of the RETeval full-field flicker ERG in the screening of diabetic retinopathy (DR) and vision-threatening diabetic retinopathy (VTDR) and to determine a suitable range of DR diagnostic reference for patients with type 2 diabetes mellitus (T2DM).MethodsThis was a cross-sectional study involving 172 subjects with T2DM, including 71 subjects without clinically detectable DR (NDR), 25 subjects with mild non-proliferative diabetic retinopathy (NPDR), 24 subjects with moderate NPDR, 27 subjects with severe NPDR and 25 subjects with proliferative diabetic retinopathy (PDR). All the subj...

CONCLUSIONS: Current evidence suggests no major differences in carbohydrate metabolism between different hormonal contraceptives in women without diabetes. We cannot make strong statements due to having few studies that compared the same types of contraceptives. Many trials had small numbers of participants and some had large losses. Many of the earlier studies had limited reporting of methods. We still know very little about women at risk for metabolic problems due to being overweight. More than half of the trials had weight restrictions as inclusion criteria. Only one small trial stratified the groups by body mass index ...
