Abstract Background Low Magnesium (Mg) dietary intake has been associated with increased risk of type 2 diabetes mellitus (T2DM). Furthermore, in patients with T2DM, hypomagnesemia is associated with worst glycaemic control. Bariatric surgery (BS) remains the most effective treatment in severe obesity and also provides resolution/improvement of T2DM. Our aim is to evaluate the association between Mg supplementation post-BS and Mg serum levels with diabetes status after BS. Methods We performed an observational study on patients with obesity and T2DM who underwent BS. Data was assessed pre-BS and one-year post-BS. Results We included a total of 403 patients with T2DM. At baseline, 43.4% of the patients had Mg deficiency. Pre-BS, patients with Mg deficiency had poorer glycaemic control – HbA1c 7.2 ± 1.6% vs 6.4 ± 1.0% (p

Patients with missing vitamin D levels or hepatic profile parameters were excluded. We divided the population according to two cut-offs of vitamin D levels (12ng/mL and 20ng/mL).Results: The included population (n=1124) had an average age of 43.3± 10.7 years and 84.3% were female. Seventy-point eight percent of the population had vitamin D levels lower than 20ng/mL and 34.8% lower than 12ng/dL. Patients with lower vitamin D levels (< 12ng/mL) had higher BMI, hip and waist circumferences and higher prevalence of hypertension. Higher FLI scores [OR= 0.77 (0.07), p< 0.01] and ALP levels [β= − 0.03 (− 0.06, − 0.01), p< 0.01] associated to lower vitamin D levels.Conclusion: Vitamin D deficiency is associated with a higher risk of hepatic steatosis in individuals with morbid obesity. Correction of vitamin D deficiency may have a beneficial role in the management of NAFLD in patients with morbid obesity.Keywords: vitamin D, fatty liver, NAFLD, obesity

Methods: One hundred patients with type 2 diabetes were interviewed. HRQoL was evaluated using the age-adjusted Short-Form 36 dimensions (physical functioning, role-physical, bodily pain, general health, vitality, social functioning, role-emotional, and mental health). Results: The mean age of the study population was 62.7±8.7 years; 54.0% were male, and 51.0% were receiving only oral hypoglycemic agents. Chronic complications were related to worse HRQoL in different dimensions: peripheral neuropathy and cardiovascular disease (all, except bodily pain), retinopathy (physical functioning, general health, vitality, and mental health), peripheral arterial disease (physical functioning, role-physical, and general health), and nephropathy (general health and vitality). Hypertension was related to worse general health and vitality. An increased number of chronic complications was associated with worse HRQoL in all dimensions of Short-Form 36 except for the bodily pain dimension. Conclusion: The presence and increased number of diabetes-related chronic complications, and the presence of hypertension were related to worse age-adjusted HRQoL. Peripheral neuropathy and cardiovascular disease were more strongly related to age-adjusted HRQoL.

The purpose of this study was to assess the relationship between health-related quality of life in patients with diabetes and sex, body mass index, type of diabetes and treatment regimens (type 1 diabetes: intensive versus conventional treatment; type 2 diabetes: insulin use versus non-insulin use), and duration of diabetes.Methods: One hundred and twenty-four patients with diabetes were interviewed. Health-related quality of life was evaluated using the age-adjusted Short-Form 36 dimensions (physical functioning, role-physical, bodily pain, general health, vitality, social functioning, role-emotional, and mental health), and related to demographic and clinical variables. Independent samples t-tests and One-Way Analysis of Variance were used to compare means of independent samples. The degree of association between pairs of variables was measured by Pearson’s (r) or Spearman’s (rs) correlation coefficients.Results: The mean age of the study population was 55.7±16.4 years; 54.8% were male, and 77.4% had type 2 diabetes. Females reported worse quality of life than males in all dimensions of the Short-Form 36, except for role-physical and bodily pain. Obese patients had worse physical functioning than normal weight and overweight patients, and worse vitality than their normal weight counterparts. Type 2 diabetic patients taking insulin had lower physical functioning and vitality than those without insulin therapy. Longer duration of diabetes was associated with lower physical functioning, role-physical, general health, vitality, role-emotional, and mental health.Conclusion: Being female, obese, having type 2 diabetes and taking insulin, and having a longer disease duration are characteristics associated with worse age-adjusted quality of life in patients with diabetes.Keywords: clinical variables, demographic variables, diabetes mellitus, health-related quality of life
