Background: Obesity is the main obstacle for metabolic control in patients with type 2 diabetes. Turkey has the highest prevalence of obesity and type 2 diabetes in Europe. The effect of obesity on the metabolic control, and the macro- and microvascular complications of patients are not apparent. Objectives: This nationwide survey aimed to investigate the prevalence of overweight and obesity among patients with type 2 diabetes and to search for the impact of obesity on the metabolic control of these patients. We also investigated the independent associates of obesity in patients with type 2 diabetes. Methods: We consecutively enrolled patients who were under follow-up for at least 1 year in 69 tertiary healthcare units in 37 cities. The demographic, anthropometric, and clinical data including medications were recorded. Patients were excluded if they were pregnant, younger than 18 years, had decompensated liver disease, psychiatric disorders interfering with cognition or compliance, had bariatric surgery, or were undergoing renal replacement therapy. Results: Only 10% of patients with type 2 diabetes (n = 4,648) had normal body mass indexes (BMI), while the others were affected by overweight (31%) or obesity (59%). Women had a significantly higher prevalence of obesity (53.4 vs. 40%) and severe obesity (16.6 vs. 3.3%). Significant associations were present between high BMI levels and lower education levels, intake of insulin, antihypertensives and statins, poor metabolic control, or the presence of microvascular complications. Age, gender, level of education, smoking, and physical inactivity were the independent associates of obesity in patients with type 2 diabetes. Conclusion: The TEMD Obesity Study shows that obesity is a major determinant of the poor metabolic control in patients with type 2 diabetes. These results underline the importance of prevention and management of obesity to improve health care in patients with type 2 diabetes. Also, the results point out the independent sociodemographic and clinical associates of obesity, which should be the prior targets to overcome, in the national fight with obesity.
Introduction:
Thyroid hormones are essential for the normal development, differentiation,
metabolic balance and physiological function of all tissues. Mean platelet volume (MPV) indicates
mean platelet size and reflects platelet production rate and stimulation. Increased platelet size has been
observed in association with known cardiovascular risk factors. The neutrophil/lymphocyte ratio
(NLR) and platelet/lymphocyte ratio (PLR) are known markers of the systemic inflammatory response.
This study aimed to investigate the effect of thyroid hormone changes by comparing platelet count,
MPV values, NLR and PLR in thyroid papillary carcinoma.
Methods:
Forty-nine females and nine males comprising a total of 58 patients were included in the
study. Clinical and laboratory parameters of patients were recorded in the following three phases of the
disease: euthyroid phase (before thyroid surgery), overt hypothyroid (OH) phase (before radioactive
iodine [RAI] treatment) and subclinical hyperthyroid (SCH) phase (six months after RAI treatment).
Results:
The mean thyroid-stimulating hormone (TSH) values of the patients in the euthyroid, OH and
SCH phases were 1.62±1.17, 76.4±37.5 and 0.09±0.07 μIU/mL, respectively. The mean MPV values
of the patients in the euthyroid, OH and SCH phases were 9.45±1.33, 9.81±1.35 and 9.96±1.21 fL,
respectively. MPV was significantly higher in the SCH phase than in the euthyroid phase (p=0.013).
Platelet count, NLR and PLR were not statistically different between the euthyroid, OH and SCH
phases.
Conclusion:
The results of this study demonstrated that the levels of MPV increased significantly in
the SCH phase in patients with papillary thyroid carcinoma (PTC), and increased MPV values contributed
to increased risk of cardiovascular complications. These findings suggest that MPV can be a valuable,
practical parameter for monitoring the haemostatic condition in thyroid disorders. No significant
difference was observed in platelet count, NLR and PLR in all stages of PTC.
Rheumatoid arthritis (RA) is a chronic, systemic and an autoimmune disease characterized by inflammation of the synovial membrane that affects approximately 1 % of the total world population. Rheumatoid factor (RF) is a widely used auto antibody in diagnosis of the RA and found positive in 50-80 % of the patients but with a lower specificity. On the other hand, anti-cyclic citrullinated peptide (anti-CCP) is the latest serological marker with a specificity around 98 %. This field survey was conducted in different regions to investigate the frequency of RF and anti-CCP and also frequency of RA in a northern province of Turkey. This study was conducted in 70 local areas (12 urban and 58 rural) in the province of Tokat, which is located in northern Turkey. The population of Tokat was reported to be 828,000 at the last census and about 530,000 individuals aged > 18 years old. The study population of 941 subjects (462 male and 479 female; urban 501 and rural 440) was selected by random sampling method among 530,000 individuals. Of the 941 healthy controls assigned to the study, 479 of them were female (51 %) and 462 of them were males (49 %), and median age of all participants was 41 ± 17. Twenty-six subjects were RF positive (2.8 %), and 9 patients were anti-CCP positive (1 %). The presence of both RF and anti-CCP antibodies has also been shown in two patients (0.2 %). In conclusion, we demonstrated that the frequency of RA was 0.53 %, RF presence was 2.8 %, and anti-CCP presence was 1 % in total 941 healthy subjects enrolled into study.
Studies suggest that determination of the TSH reference intervals may differ due to environmental influences or due to age, gender, and race. It is suggested that the lower limit of normal TSH for the adult Turkish population would be 0.38 mIU/L and the upper limit similar to the traditional value of 4.2 mIU/L. If each clinician uses their population-specific reference interval for TSH, thyroid function abnormalities can be accurately estimated.
TNF-α-308GA and IL-6 -174CC gene polymorphisms are involved in susceptibility to GD in Turkish population. The polymorphism hypothesis in pro-inflammatory cytokines might be involved in predisposition to GD.
CFR is significantly lower in adults with GH deficiency than in controls. Direct correlation between CFR and IGF-1 concentrations suggests GH replacement could improve microvascular function and thereby could decrease cardiovascular morbidity and mortality in AGHD.
