Antioxidant therapies, including α-lipoic acid, are widely used to treat various systemic diseases including diabetes mellitus. The aim of this study was to measure the lipid metabolism parameters, as well as the activity of lipid peroxidation and antioxidant defense reactions, in men with type 1 diabetes mellitus (T1DM) during treatment with α-lipoic acid. Twenty-four reproductive-age T1DM males with an unsatisfactory glycemic profile were examined. Twenty-eight practically healthy men of similar age were used as the control group. Spectrophotometric, fluorometric, and enzyme-linked immunoassay methods were used. T1DM was characterized by increased values of lipid metabolism components, including total cholesterol, triacylglycerides (TG), and very-low-density lipoproteins (VLDL). In the lipid peroxidation system, increased levels of the primary products (conjugated dienes), secondary products (thiobarbituric acid reactants), and final products (Schiff bases) were observed in T1DM patients compared to the control group. Retinol values were also increased. After treatment, there was a decrease in TG, VLDL, and Schiff bases levels and an increase in the retinol level compared to before treatment. These results expand our understanding of the pathogenetic mechanisms of T1DM and suggest that α-LA treatment may be beneficial for type 1 diabetics.","PeriodicalId":43011,"journal":{"name":"AIMS Medical Science","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90294011","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Obese children have a higher prevalence of skin lesions than normal weight children. The present study is an updated-on state of the art of studies describing the association between childhood obesity and related skin lesions. The most frequent obesity-associated dermatological complications in children are acanthosis nigricans and acrochordons, atopic dermatitis, skin infections, and endocrinological changes including hyperinsulinism and hyperandrogenism. Other common skin manifestations associated with obesity are striae distensae and plantar hyperkeratosis. Although the causes of the majority of the skin lesions associated with obesity are not known, the larger mass of adipose tissue and the secretion of peptides (cytokines, hormones, etc.) from enlarged fat cells due to obesity could lead to skin lesions. Therefore, the prevention of obesity is essential to avoid most skin-associated lesions.","PeriodicalId":43011,"journal":{"name":"AIMS Medical Science","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83703089","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Objective: The aim of this study was to assess the link of socio-demographic and anthropometric characteristics with the management and glycemic control in children with type1 diabetes (T1D). Materials and Methods: The study included a sample of 184 children with T1D of 15 years old or less. A structured questionnaire was used to collect information on socio-demographic status, characteristics and complications of the disease, diabetes management, diet, physical activity and therapeutic education of participants. Weight and height were measured and body mass index calculated. Results: The mean age of the patients surveyed was 8.49 ± 4.1 years; the majority (68.5%) was of school age, female (53.2%) and was from low socioeconomic level (83.2%). Only 20.1% of the patients had a good glycemic control. The low socioeconomic status and overweight or obesity were significantly more prevalent in children with poor compared to those with good glycemic control (P ≤ 0.001). Multivariate analysis revealed an association of poor glycemic control with the family history of diabetes (adjusted OR = 38.70, 95% CI: 11.61, 128.98) and the absence of therapeutic education (adjusted OR = 3.29, 95% CI: 1.006, 10.801).

Therefore, any pathologic processes within OCs, including infectious or inflammatory sinusitis, fungus ball, inverted papilloma, mucocele, or sino-nasal malignancy can cause devastating ophthalmologic complications. We aimed to define the different optic neuropathy conditions related to isolated OC mucoceles, determine the different symptoms of each condition and its risk factors, and explore the efficacy of the relevant diagnostic tools and treatment strategies. Methodology A comprehensive electronic search with time and language restrictions was conducted. Several known databases were included: PubMed, The Cochrane Library, and Web of Science from 1990 to 2020. We combined the search terms and limited the study to the English language. We removed duplicates, and the articles were screened based on title, abstract, and full text according to the PRISMA checklist. Results The electronic search strategy conducted in this review resulted in 409 hits. After removing duplicate studies and studies with inadequate information, 20 case studies were finally included in this analysis, 65% of which presented men (n = 13), and seven presented women (35%). The mean age reported in these studies was 54.75 with a standard deviation of 14.62 years. We found that visual disturbances that can lead to visual loss were present in most cases (75% of cases). Other symptoms included headache (35%) and eye pain (30%). The risk factors for developing optic neuropathy conditions related to OC mucoceles include being Asian and elderly with a history of either nasal or eye conditions. Our findings showed that the mean time between the onset of symptoms and intervention was 16.8 ± 21.8 days. Most patients underwent endoscopic sinus surgery to remove the OC mucocele (18/20; 90%) with a success rate of 77%. Pharmacologic intervention as a solo treatment (IV corticosteroids or /and antibiotic) was used in only six patients, with a success rate of only 33%. Computed tomography (CT) and magnetic resonance imaging (MRI) is the most commonly used diagnostic tools, with diagnostic success rates of 40% and 82.3%, respectively. Conclusion Optic neuropathy conditions related to OC mucoceles are very rare. However, a higher incidence of these conditions was observed in elderly Asian patients with a history of nasal or optic conditions. Visual disturbances are the most common symptoms accompanying any type of eye condition. Endoscopic sinus surgery is considered an effective and safe intervention for these patients, and the period between the onset of symptoms and surgery does not affect the outcomes of the surgery. Furthermore, treatment with corticosteroids and/or antibiotics cannot replace surgery and it can also worsen the condition. Moreover, MRI is superior to CT scans for demonstrating this abnormality, and both are supe","PeriodicalId":43011,"journal":{"name":"AIMS Medical Science","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74483009","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A comprehensive search of several databases, including Cochrane Library, PubMed, and Web of Science was conducted to December 2020. Twenty-four clinical studies were assessed. According to the results, it is clear that DJBL provides effective weight reduction at 6–12 months and significant improvements in parameters associated with metabolic syndrome and cardiovascular disease. This technique also has potential to reduce comedications in patients with obesity and type 2 diabetes. Although these positive effects of DJBL are clear, its effect on liver, pancreatic functions, and inflammation markers are not clear yet. In addition, the overall and serious complication (gastrointestinal bleeds, pancreatitis, hepatic abscess, obstruction of the sleeve, biliary colic without cholecystitis and cholangitis) rate causing from the DJBL is very high. DJBL has not been approved by the Food and Drug Administration due to the frequency and severity of complications it causes.

Ideal glycemic control can be attained when patients adhere to self-management behaviors such as consistent monitoring of blood glucose (BG) levels, staying physically active, taking medications, and eating a healthy diet. Aim The present study has the following aims: (1) to assess knowledge of self-care and the initiative of type 2 diabetic patients in medication compliance, making suitable food choices, regular physical exercise and BG monitoring, (2) to evaluate diabetic patient self-management by adhering to instructions of healthcare provider in attaining outcomes such as medication adherence, appropriate food choices, prescribed physical exercise, and self-monitoring of BG levels and determination of glycated hemoglobin (HbA1c) levels at clinic visits and (3) to determine whether there are associations between BG control (glucose and HbA1 levels) and sociodemographic factors (i.e., age, education, employment status) as well as knowledge of self-care and the number of years persons had type 2 diabetes mellitus (T2DM). Method The study is a cross-sectional study that utilized a quantitative methodology. The study population consisted of 101 T2DM patients. The researchers used a 12-point interviewer administered questionnaire to solicit information on socio-demographics, knowledge of self-care, and self-management of T2DM, including physical activity and selecting appropriate food choices, and evidence of glycemic control, such as HbA1c and random blood glucose (RBG) levels. Researchers analyzed the data using SPSS version 17.0 and Microsoft Excel 2007. Authors applied an analytical statistical analysis with a 95% confidence level. Results The findings revealed that 90.1% of respondents indicated that they knew how to take their medications. Results also indicated that there was no association of knowledge of self-care with the number of years persons had T2DM. Among the total respondents, 53.5% had poor compliance to prescribed medication, and women were 1.2 times more likely not to comply with medication. In addition, 65.3% of respondents reported poor compliance with physical exercise and 81.2% of respondents indicated poor compliance in self-monitoring BG. Conclusion The findings from this study reveal that the majority of patients with T2DM knew how to take their medications. However, compliance with physical exercise and self-monitoring BG were less than satisfactory. Didactic interventions focusing on the acquisition of knowledge and information will empower patients and improve their self-care and management.","PeriodicalId":43011,"journal":{"name":"AIMS Medical Science","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73353542","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
