Serological Screening for Celiac Disease and Gastrointestinal Absorption Disorders in Patients with Autoimmune Endocrine Diseases.

Celiac disease (CD) accompanying autoimmune endocrine diseases (AED) is generally asymptomatic. This study aimed to evaluate the frequency of clinically overt or silent CD in patients diagnosed with autoimmune endocrinopathy and the clinical effects of silent CD in these endocrinopathies. The study included 166 patients with known or newly diagnosed mono-/polyglandular AED and 90 age- and gender-matched healthy controls. The patients were classified into four groups: type 1 diabetes mellitus (DM) (n=44), Hashimoto's thyroiditis (HT) (n=68), Addison's disease (AD) (n=17), and autoimmune polyglandular syndrome (APS) (n=37). All subjects were serologically screened for tissue transglutaminase antibody (tTG) IgA and IgG. In addition, to evaluate the possible systemic consequences of CD, serum parathormone (PTH), 25-hydroxicholecalsiferol (25-OH-Vit D), vitamin B12, folic acid, iron, iron-binding capacity (IBC), and ferritin levels were measured. In the total series, 193 (75.4%) individuals were females, and 63 (24.6%) were males. TTG IgA antibody positivity was found in 23 among 166 patients, while no positivity was encountered in the healthy control group. The highest rates of positive tTg IgA frequency were detected in AD, with 29.4% (5/17). Serum 25-OH-Vit D, vitamin B12, folic acid, iron, and ferritin levels were significantly lower in AEDs compared to controls (p<0.001), and the lowest these parameters were detected in patients with AD. The serologic CD prevalence is higher in autoimmune mono-/and polyglandular endocrine diseases than in the control group. The data support recommends regular screening for CD in all patients with AEDs.

Assessment of awareness about COVID-19 disease and vaccine uptake.

OBJECTIVE: To evaluate the awareness of individuals about coronavirus disease-2019 disease and vaccines during the pandemic. METHODS: The descriptive, cross-sectional survey-based study was conducted at family health centres in the Bursa province of Turkiye from July 1 to 7, 2021. The face-to-face survey of registered individuals had 20 items that measured coronavirus disease-2019 and vaccines. The scale was named the Coronavirus Disease-2019 and Vaccine Awareness level. It was carried out by family physicians using an online weblink. The Cronbach alpha coefficient was 0.87. Data was analysed using SPSS 25. RESULTS: Of the 228 subjects, 129(56.6%) were males and 99(43.4%) were females. The overall mean age was 27.82±10.28 years. Awareness levels were high with a mean value of 2.41±0.31. Female participants were more aware than males (p=0.04) and those with monthly income between 2000-10000 Turkish lira had lower awareness level compared to other income groups (p=0.03). Marital status (p=0.32), education level (p=0.49) comorbidities (p=0.23), regular drug usage (p=0.13) and exercise status (p=0.24) did not affect the awareness levels. Non-smokers were more aware than the smokers (p=0.01). CONCLUSIONS: The level of awareness about coronavirus disease-2019 and its vaccine was higher in the female gender and non-smokers, it was lower in the middle-income group.

Assesment of attainment of recommended TSH levels and levothyroxine compliance in differentiated thyroid cancer patients.

OBJECTIVE: Thyroid-stimulating hormone (TSH) suppression treatment can induce signs and symptoms of hyperthyroidism and hypothyroidism due to inappropriate treatment or poor compliance to the treatment. The current study aimed to investigate TSH levels, frequency of being on target TSH, adherence to levothyroxine (LT4) suppression treatment in differentiated thyroid cancer (DTC) patients after surgery in a multicentric setting. DESIGN AND PATIENTS: This multicentric cross-sectional study was conducted at 21 medical centres from 12 cities in Turkey. DTC patients followed at least one year in the same center included in the study. Clinical data, serum TSH, free thyroxine (FT4), thyroglobulin (Tg) and anti-Tg levels were recorded during the most recent visit. Body mass index, systolic and diastolic blood pressures, pulse rate were measured. LT4 doses were recorded and doses per kilogram of bodyweight were calculated. Pill ingestion habits recorded and adherence to the therapy were evaluated using the Morisky Medication Adherence Scale and categorized as good, moderate or poor compliant based on their scores. Risk stratification forpredicting the disease persistance and/or reccurence was assessed using the American Joint Committee on Cancer-7th edition thyroid cancer staging calculator. TSH serum concentrations were classified as severe suppression (TSH < 0.01 mU/L), moderate suppression (TSH: 0.01-0.1 mU/L), mild suppression (TSHL 0.1-0.5 mU/L), euthyroid (TSH: 0.5-4 mU/L) and hypothyroid (TSH > 4 mU/L). TSH levels can also be classified as on being on target, under the target, or beyond over the target, according to the American Thyroid Association recommendations. RESULTS: A group of 1125 patients (F/M: 941/184, 50.7 ± 11.7 years) were included in the study. The mean LT4 daily dosage was 132.4 ± 39.6 mcg/day. TSH levels showed severe suppression in 99 (%8.8) patients, moderate suppression in 277 (%24.6) patients and mild suppression in 315 (%28) patients and euthyroid range in 332 (%29.5) patients and hypothyroid range in 97 (8.6%). TSH levels were in target in 29.2% of the patients 20.4% of the patients were undertreated, 50.4% overtreated. The daily LT4 dose and LT4 dose/kg were significantly higher in the severe suppression group (p < .001, p < .001). According to the Morisky scale, 564 patients (50.1%) were good compliant, 368 patients (32.7%) were moderate compliant, and 193 patients (17.1%) were noncompliant. Patients with poor compliance need a higher dose of LT4 compared to the good compliance group (p < .001). TSH levels of patients with good compliance were 0.67 ± 1.96 mU/L and TSH with poor compliance was 2.74 ± 7.47 mU/L (p < .001). TSH levels were similar in patients on fixed and alternating dosages. CONCLUSION: In 29.2% of the DTC patients, serum TSH levels were at target levels. Remaining of the study group have TSH levels under or over treatment range, exposing the patient to medication side effects. Majorty of the study group 82.8% have good or moderate adherence to LT4 therapy. Reaching TSH targets requires simplified and applicable guidelines and following the guideline recommendations.

Identifying Clinical Characteristics of Hypoparathyroidism in Turkey: HIPOPARATURK-NET Study.

Hypoparathyroidism is an orphan disease with ill-defined epidemiology that is subject to geographic variability. We conducted this study to assess the demographics, etiologic distribution, treatment patterns and complication frequency of patients with chronic hypoparathyroidism in Turkey. This is a retrospective, cross-sectional database study, with collaboration of 30 endocrinology centers located in 20 cities across seven geographical regions of Turkey. A total of 830 adults (mean age 49.6 ± 13.5 years; female 81.2%) with hypoparathyroidism (mean duration 9.7 ± 9.0 years) were included in the final analysis. Hypoparathyroidism was predominantly surgery-induced (n = 686, 82.6%). The insulting surgeries was carried out mostly due to benign causes in postsurgical group (SG) (n = 504, 73.5%) while patients in nonsurgical group (NSG) was most frequently classified as idiopathic (n = 103, 71.5%). The treatment was highly dependent on calcium salts (n = 771, 92.9%), calcitriol (n = 786, 94.7%) and to a lower extent cholecalciferol use (n = 635, 76.5%) while the rate of parathyroid hormone (n = 2, 0.2%) use was low. Serum calcium levels were most frequently kept in the normal range (sCa 8.5-10.5 mg/dL, n = 383, 46.1%) which might be higher than desired for this patient group. NSG had a lower mean plasma PTH concentration (6.42 ± 5.53 vs. 9.09 ± 7.08 ng/l, p < 0.0001), higher daily intake of elementary calcium (2038 ± 1214 vs. 1846 ± 1355 mg/day, p = 0.0193) and calcitriol (0.78 ± 0.39 vs. 0.69 ± 0.38 mcg/day, p = 0.0057), a higher rate of chronic renal disease (9.7% vs. 3.6%, p = 0.0017), epilepsy (6.3% vs. 1.6%, p = 0.0009), intracranial calcifications (11.8% vs. 7.3%, p < 0.0001) and cataracts (22.2% vs. 13.7%, p = 0.0096) compared to SG. In conclusion, postsurgical hypoparathyroidism is the dominant etiology of hypoparathyroidism in Turkey while the nonsurgical patients have a higher disease burden with greater need for medications and increased risk of complications than the postsurgical patients.

The effect of calcineurin inhibitors on anthropometric measurements in kidney transplant recipients.

BACKGROUND: This study was designed to investigate the effect of calcineurin inhibitors (CNIs), cyclosporine (CsA), and tacrolimus (Tac) on anthropometrics in kidney transplant recipients. METHODS: 111 of 128 adult kidney transplant recipients who received post-transplant CNIs were included in this retrospective study. Anthropometrics were recorded in the pre-transplant and post-transplant 4-year follow-up periods (1st, 3rd, 6th, 12th, 24th, 36th and 48th months). RESULTS: Compared to pre-transplant values, significant increases in body weight and body mass index (between 3rd and 48th months), waist and hip circumferences (between 1st and 48th months), waist-to-hip ratio (between 1st and 3rd or 6th months) and neck circumference (between 1st and 12th or 24th months) were observed in both CsA and Tac groups. A significant increase was noted in post-transplant body fat percentage values for the 3rd to 24th months in the CsA group, whereas for the 24th to 48th months in both CsA and Tac groups. Hip circumferences percentage changes from the pre-transplant period to the 1st, 12th and 24th months were significantly higher in CsA than in the Tac group. At each time point, there was no significant difference in percentage changes for other anthropometric parameters between the CsA and Tac groups. De novo diabetes mellitus developed in 8.3% of the CsA group and 19.1% of the Tac group. CONCLUSIONS: After a successful kidney transplant, anthropometric measurements increase in most recipients. Although the effect of calcineurin inhibitor type on weight gain is unclear, a regression analysis showed that CNI type was not a risk factor for the development of obesity in the 48th month. However, it is helpful to be cautious about its dyslipidemic effect in patients using CsA and the potential hazards of using Tac in patients with a diabetic predisposition.

Comparison of the Effect of Anesthetic Agents on Blood Levels of Parathyroid Hormone and Ionized Calcium: A Prospective Randomized Controlled Trial.

The aim of this randomized control trial is to compare the effect of anesthetic agents on blood levels of parathyroid hormone and ionized calcium. 77 American Society of Anesthesiologists I-II patients who would undergo laparoscopic cholecystectomy were enrolled into this prospective study and randomized into 3 groups with sealed envelope technique as Group S: sevoflurane, Group D: desflurane, and Group TIVA: total intravenous anesthesia. The first blood sample was used to check the baseline blood levels of parathyroid hormone and ionized calcium. In Group S or D, maintenance of anesthesia was being performed with 1 MAC (minimum alveolar concentration) sevoflurane or desflurane, respectively, while in Group TIVA, it was performed with 150 mcg/kg/min propofol and 1 mcg/kg/min remifentanil IV infusions. At the 30th minute of anesthesia and at the 1st hour of end of anesthesia, 2nd and 3rd blood samples, respectively, were used to check the blood levels of PTH and Ca. During perioperative period, hemodynamic parameters were also noted. Blood levels of parathyroid hormone at the 30th min after anesthesia were found to be significantly different between groups (P=0,01). The PTH level at the 30th min after anesthesia was found significantly higher in Group S than that of Groups D and TIVA (P=0.005 and P=0.001, respectively). Blood levels of ionized calcium at 30th min after anesthesia were found significantly different between groups (P=0,048). It was found significantly higher in Group TIVA than that in Group S (P=0.024). Desflurane seems to be the best agent for parathyroidectomy procedures. Future research studies are needed to be conducted to reach out more correct and valuable outcomes.

Evaluating a physicians' perspective on the use of probiotics and vitamins against coronavirus disease.

OBJECTIVE: To evaluate the perspective of family physicians on probiotics and vitamins against coronavirus disease-2019. METHODS: The cross-sectional study was conducted from June 1 to 30, 2021, after approval from the ethics review committee of Bursa Uludag University, Bursa, Turkey, and comprised family physicians of either gender working at family health centres in the country. Data was collected using an online questionnaire to measure the sociodemographic characteristics, habits, health status related to coronavirus disease-2019, and their knowledge, awareness and behaviour towards the use of probiotics and vitamins during the pandemic. Data was analysed using SPSS 25. RESULTS: Of the 218 family physicians, 130(59.6%) were male and 88(40.4%) were female. The overall mean age was 46.82±5.85 years, mean professional experience was 22.32±8.75 years, and mean experience in family medicine was 10.14±3.51 years. The knowledge and awareness level about coronavirus disease-2019 was high 4.18±0.58, exposure to the disease 3.36±0.83 and their inclination towards the use of vitamins and probiotics 1.68±0.75 was low. Among the participants, 90(41.3%) used probiotic products and 120(55%) used drugs, such as vitamins and minerals. Vitamin C 99(45.4%) was the most commonly used supplement. CONCLUSIONS: Physicians' knowledge and awareness and a realistic scientific approach are important when recommending supplements, such as probiotics, vitamins and minerals, to individuals during the pandemic.

Does vitamin D level have an effect on COVID-19 positivity and COVID-19 related mortality? A retrospective study.

OBJECTIVE: To explore the possible relationship between vitamin D and coronavirus disease-2019 in an urban population known to have relatively low vitamin D levels. METHODS: The retrospective study was conducted in Bursa, Turkey, and comprised data of 30 family health centers from March 1 to December 15, 2020, related to diagnosed inpatients of coronovairus disease-2019. The diagnosis was based on polymerase chain reaction test for severe acute respiratory syndrome coronavirus-2 infection. Vitamin D levels of these patients were obtained from previous records and compared with those without polymerase chain reaction positivity. Vitamin D levels of positive patients who survived were compared with those who died of coronavirus disease-2019. Data was analysed using SPSS 21. RESULTS: Of the 2,105 patients whose data was retrieved, 212(10%) were positive for coronavirus disease-2019, while 1,893(90%) were negative. Among the positive patients, 89(42%) were men and 123(58%) were women. The overall median age was 45 years (Q1-Q3(Q1: first quartile, Q3: third quartile): 35-56 years). Vitamin D level was not significantly different between the positive and negative patients (p>0.05). Among the positive patients, 2(0.9%) patients did not have new admissions to the designated centers and their data was excluded, 206(97.2%) survived and 4(1.9%) died. There was no significant difference in vitamin D levels between those who survived and those who died (p>0.05). CONCLUSIONS: There was no significant relationship found between vitamin D levels and coronavirus disease-2019 infection and related deaths.

Knowledge, attitude, and practice towards COVID-19: Research to develop a measuring instrument.

OBJECTIVE: To evaluate the knowledge, attitudes, and behaviors of individuals about COVID-19 and to develop a valid and reliable scale that can measure these items about COVID-19 and other similar pandemic processes. DESIGN: Methodological scale study with a quantitative approach. SITE: Carried out at the Uludag University Family Health Center in Bursa, Turkey. PARTICIPANTS: 415 individuals in the first phase and 367 in the retest phase. INTERVENTIONS: Carried out between March 1, 2021, and April 30, 2021. MAIN MEASUREMENTS: Reliability and factor analyses were performed and validity was evaluated. In factor analysis, a scale with 4 factors and 30 questions was obtained. Confirmatory factor analysis (CFA) was applied to the factor scores of the scale. Factors were named A-General Culture, B-Mask, Distance and Cleanliness, C-Mental Status, and D-Way of Information. A 3-point Likert-type scoring system was created for the responses. RESULTS: Cronbach's alpha value was 0.894. In factor modeling, 3 of the confirmatory factor analysis fit indices were good and 4 of them were acceptable, so our model was found to be appropriate. The scale was highly reliable, according to internal and external consistency coefficients. The scale was named the Turkey COVID-19 Attitude Scale. p values<0.05 were considered statistically significant. CONCLUSIONS: The valid and reliable Turkey COVID-19 Attitude Scale, which we developed to evaluate the knowledge, attitudes, and behaviors of individuals about COVID-19, can be used to guide research during COVID-19 and future pandemics.

Utilization of statins and LDL-cholesterol target attainment in Turkish patients with type 2 diabetes - a nationwide cross-sectional study (TEMD dyslipidemia study).

BACKGROUND: Attaining acceptable levels of LDL Cholesterol (LDL-C) significantly improves cardiovascular (CV) outcomes in patients with type 2 diabetes mellitus (T2DM). The LDL-C target attainment and the characteristics of patients attaining these targets were investigated in this study. Furthermore, the reasons for not choosing statins and the physicians' attitudes on the treatment of diabetic dyslipidemia were also examined. METHODS: A nationwide, cross-sectional survey was conducted in tertiary centers for diabetes management. Adult patients with T2DM, who were under follow-up for at least a year in outpatient clinics, were consecutively enrolled for the study. LDL-C goals were defined as below 70 mg/dL for patients with macrovascular complications or diabetic nephropathy, and below 100 mg/dL for other patients. Data about lipid-lowering medications were self-reported. RESULTS: A total of 4504 patients (female: 58.6%) were enrolled for the study. The mean HbA1c and diabetes duration was 7.73 ± 1.74% and 10.9 ± 7.5 years, respectively. The need for statin treatment was 94.9% (n = 4262); however, only 42.4% (n = 1807) of these patients were under treatment, and only 24.8% (n = 448) of these patients achieved LDL-C targets. The main reason for statin discontinuation was negative media coverage (87.5%), while only a minority of patients (12.5%) mentioned side effects. Physicians initiated lipid-lowering therapy in only 20.3% of patients with high LDL-C levels. It was observed that the female gender was a significant independent predictor of not attaining LDL-C goals (OR: 0.70, 95% CI: 0.59-0.83). CONCLUSIONS: Less than 50 % of patients with T2DM who need statins were under treatment, and only a quarter of them attained their LDL-C targets. There exists a significant gap between the guideline recommendations and the real-world evidence in the treatment of dyslipidemia in T2DM.

May hemocytometer parameters be a biomarker in distinguishing between adrenal adenomas and carcinomas and in prognosis of adrenocortical carcinomas?

Recently, studies have reported that inflammatory response and elevated platelet counts are associated with several cancers. In the present study, we aimed to evaluate hemocytometer parameters in differentiating adrenal adenoma and carcinoma, and the prognostic utility of hemocytometer parameters in adrenocortical carcinoma (ACC). We included 30 patients with nonfunctional adrenal adenoma and 13 patients with ACC having undergone surgery between 2005 and 2017 and followed up postoperatively at our centre. The neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR), red blood cell distribution width (RDW), mean platelet volume (MPV) and plateletcrit (PCT) were evaluated preoperatively in all patients included in the study. There was a significant difference between the adrenal adenoma and ACC groups in terms of neutrophil and lymphocyte counts, NLR and PLR. There was no significant difference between the two groups in terms of platelet count and MPV, but PCT levels were significantly lower in ACC group. There was no statistically significant difference between recurrent and/or metastasis positive patients and negative ones according to NLR, PLR, RDW and MPV. There was a statistically significant difference in RDW levels and tumor diameter between the groups. Our study is the first to evaluate hemocytometer parameters in differentiating adrenal adenomas and carcinomas, and also in the prognosis of ACC. The present study suggested that the hemocytometer parameters may be a marker in the differential diagnosis of adrenal adenomas and carcinomas. However, our study also showed that these parameters had no prognostic value in ACC.

The association between cardiac valvular calcification and fetuin-A levels in kidney transplant recipients.

OBJECTIVES: Low fetuin-A levels in hemodialysis patients can be associated with development of vascular and valvular calcifications. The mechanisms underlying vascular and valvular calcifications are multifactorial. There are a few studies showing the relationship between low fetuin-A levels and valvular calcification after kidney transplantation. We aimed to evaluate the association between serum fetuin-A levels and valvular calcification in kidney transplant recipients. METHODS: The cardiac valvular calcification was assessed by echocardiography in 56 recipients. Patients were divided into two groups as those with (n = 11) and without (n = 45) aortic and/or mitral valve calcification. The extent of valvular calcification was visually assessed according to the standard visual score method: moderately (multiple larger spots) and heavily calcified (extensive thickening and calcification) of all cusps. Serum fetuin-A levels were measured. RESULTS: The demographic features of both groups were comparable. There was no significant difference between regular physical exercise (63.6% vs. 55.6%), obesity (18.2% vs. 17.8%), abdominal obesity (54.5% vs. 46.7%), smoking (0% vs. 13.3%), hypertension (63.6% vs. 68.9%), left ventricular hypertrophy (45.5% vs. 33.3%) and diabetes mellitus (9.1% vs. 20%) ratios in groups with or without valvular calcification, respectively (p > 0.05). Fetuin-A levels of both groups did not differ. Fetuin-A levels positively correlated with serum creatinine (r 0.326, p = 0.014), and negatively correlated with estimated glomerular filtration rate (r - 0.297, p = 0.026). CONCLUSIONS: We could not find a relationship between serum fetuin-A levels and valvular calcification in kidney recipients. In this population, further studies are needed to assess the role of serum fetuin-A in valvular calcification.

General and abdominal obesity prevelances and their relations with metabolic syndrome components.

OBJECTIVE: To evaluate the frequency of obesity and its relation of metabolic syndrome. METHODS: The data from the records of the consecutive adult residents of Bursa province in Turkey who were admitted to the family health centers from the 1st January to the 31st December 2016 were evaluated retrospectively. The population size was 2901396 (N) and the sample size was at least n=17729. A total of 17812 participants (10939 females, 6873 males) were included in this retrospective observational study. Sociodemographic characteristics, diseases, used medication and smoking, height, weight, waist and hip circumferences (WaC and HC) were recorded from the files. RESULTS: The mean age of all subjects was 46.1 years, the mean BMI was 28.1 kg/m2 with a mean WaC of 91.3 cm, HC of 104.7 cm, WHR of 0.87. The prevalence of obesity in Bursa was found to be 32.2% (37.8% in females and 23.3% in males) according to BMI, 63.2% (69.7% in females, 52.9% in males) according to waist and hip circumferences. CONCLUSIONS: Preventive measures should be taken by health authorities to prevent the rapid increase in general and abdominal obesity that may lead to serious comorbidities.

Is Parenteral Levothyroxine Therapy Safe in Intractable Hypothyroidism?

CASE: A 32-year old woman was admitted to the hospital due to intractable hypothyroidism refractory to high dose of oral l-thyroxine therapy. She underwent total thyroidectomy and radioactive iodine therapy due to papillary thyroid cancer. After excluding poor adherence to therapy and malabsorption, levothyroxine absorption test was performed. No response was detected. Transient neurologic symptoms developed during the test. She developed 3 attacks consisting of neurologic symptoms during high dose administration. The patient was considered a case of isolated l-thyroxine malabsorption. She became euthyroid after intramuscular twice weekly l-thyroxine therapy. DISCUSSION: There are a few case reports regarding isolated l-thyroxine. We report successful long term results of twice weekly administered intramuscular l-thyroxine therapy. We also draw attention to neurologic side effects of high dose l-thyroxine therapy.

Cytokine signal suppressor (SOCS) 1-1478 CA/del gene polymorphism in Turkish patients with polycystic ovary syndrome.

Eighty-four subjects, premenopausal female patients (n = 42, mean (SD) age: 26.4 (4.2) years) diagnosed with polycystic ovary syndrome (PCOS) and age-matched healthy volunteers (n = 42, mean (SD) age: 27.6(3.4) years), were included in this study. Data on physical examination, anthropometric measurements and blood biochemistry analysis were recorded for each subject along with analysis for SOCS1-1478 CA/del polymorphism by polymerase chain reaction-restriction fragment length polymorphism. The relation of SOCS1-1478 CA/del polymorphism to PCOS status and insulin resistance was analysed via logistic regression analysis. Mean (SD) levels for BMI (28.5(6.5) vs.22.5 (4.9) kg/m2, p < .001), HOMA-IR (3.1(1.8) vs.1.5 (1.0), p < .001), LDL-cholesterol (115.9(32.7) vs.100.7 (27.3)mg/dL, p = .03) and triglyceride (113.8(64.9) vs.83.3(36.3)mg/dL, p = .017) were significantly higher in patients. Groups were similar in terms of SOCS1-1478 CA/del polymorphism. No significant relation of this polymorphism was noted to PCOS and HOMA-IR. Our findings revealed no difference between groups in terms of the rate of SOCS1-1478 CA/del polymorphism, and no significant relation of this polymorphism to insulin resistance and PCOS status. Impact statement Polycystic ovary syndrome (PCOS), the most common cause of anovulation and the most commonly encountered form of female endocrine disease. SOCS proteins have been suggested to play a fundamental role in the negative feedback regulation of the JAK-STAT pathway, which is the major signalling pathway involved in a wide range of physiologic and pathologic processes, including inflammatory diseases, malignancies and immune disorders. Pathways involving the induction of suppression of SOCS proteins were also shown likely to be involved in mediating cytokine-induced insulin resistance. The present study was designed to determine the frequency of SOCS1-1478 CA/del gene polymorphism in patients with PCOS in relation to healthy controls and insulin resistance. Our findings revealed significantly higher rates of insulin resistance, obesity and dyslipidaemia in Turkish patients with PCOS compared with age-matched healthy controls, while no difference between study groups in terms of the rate of SOCS1-1478 CA/del polymorphism along with no significant relation of SOCS1-1478 CA/del polymorphism to insulin resistance and PCOS status. Future larger scale studies with the application of standardised diagnostic methods and criteria, and of state-of-the-art modern techniques including genomics, proteomics and pharmacogenetics would provide better understanding of the association between PCOS and genomic variants.

Relationship between glycemic control, microalbuminuria and cognitive functions in elderly type 2 diabetic patients.

AIM: The prevalence of diabetes is increasing in elderly populations, and is thought to be an important risk factor for cognitive dysfunction in this age group. METHODS: The study included 104 patients aged over 60 years who were followed-up for type 2 diabetes for at least 6 months, in addition to 44 controls. Glycemic parameters, microangiopathic complications, microalbumin elimination, and the Standardized Mini Mental State Examination (SMMSE) scores were used as indicators of cognitive function. RESULTS: The SMMSE scores of diabetic patients were significantly lower than the control group (p < 0.05). The average SMMSE score for normoalbuminuric diabetic patients was 22.36 ± 4.66, compared with 22.61 ± 4.90 for the microalbuminuria patients (p = 0.84). A positive correlation was found between SMMSE scores and patients' hemoglobin values and education levels, whereas a negative correlation was noted between SMMSE scores and systolic and diastolic blood pressures and hemoglobin A1c levels (p < 0.05). Patients with diabetic neuropathy, a microvascular complication of diabetes, were found to have significantly lower SMMSE scores (p = 0.011). CONCLUSION: Elderly diabetic patients showed decreased cognitive function compared to volunteers. No relationship was established between microalbuminuria and cognitive functions, although diabetic neuropathy was found to be related to decreased cognitive function.

Retrospective Evaluation of Bone Metastases in Patients With Thyroid Malignancy: A Single-Center Experience.

Background Thyroid cancer is one of the five most common cancers causing bone metastasis. If there is an increase in serum thyroglobulin-antithyroglobulin levels in differentiated thyroid cancer or calcitonin levels in medullary thyroid cancer, patients should be evaluated for recurrence and distant metastasis. The skeleton is the second most common site of distant metastasis in thyroid cancer after the lung. Bone metastases cause pain, fractures, and spinal cord compression, severely reducing the quality of life. They are associated with poor prognosis. Bone metastases severely reduce the quality of life. This study aimed to retrospectively evaluate the diagnosis and follow-up of patients with thyroid cancer with bone metastases diagnosed at our center. Methodology A total of 1,390 patients diagnosed with thyroid malignancy at our center between 2010 and 2023 were reviewed retrospectively. The study included 27 patients with differentiated and medullary thyroid cancer who had bone metastases. Results Of 27 patients, 19 (70.4%) had differentiated and eight (29.6%) had medullary thyroid cancer. Papillary thyroid cancer constituted 22.2% (n = 6) and follicular thyroid cancer constituted 14.8% (n = 4) of the cases. Papillary carcinoma follicular variant, oncocytic, and poorly differentiated thyroid cancer were diagnosed with similar frequency, each accounting for 11.1% (n = 3). It was found that vertebrae were most commonly involved, followed by the pelvis, sternum, costae, femur and patella, shoulder and humerus, cranium, and scapula. The five-year survival rate was 72%, and the 10-year survival rate was 53%. Conclusions The number of patients with papillary cancer was the highest, but the rate of bone metastases was the lowest in this group. The highest rate of bone metastases was found in patients with poorly differentiated, oncocytic, medullary, follicular, and papillary cancer, respectively. The results obtained in this study reveal the necessity and importance of bone metastasis evaluation in patients with thyroid cancer.

Comparative genotoxic and cytotoxic effects of the oral antidiabetic drugs sitagliptin, rosiglitazone, and pioglitazone in patients with type-2 diabetes: a cross-sectional, observational pilot study.

This cross-sectional, observational pilot study was designed to investigate the frequency of different endpoints of genotoxicity (sister-chromatid exchange, total chromosome aberrations, and micronucleus formation) and cytotoxicity (mitotic index, replication index, and nuclear division index) in the peripheral lymphocytes of patients with type-2 diabetes treated with different oral anti-diabetic agents for 6 months. A total of 104 patients who met the American Diabetes Association criteria for type-2 diabetes were enrolled in the study. Of the 104 patients, 33 were being treated with sitagliptin (100mg/day), 25 with pioglitazone (30mg/day), 22 with rosiglitazone (4mg/day), and 24 with medical nutrition therapy (control group). The results for all the genotoxicity endpoints were significantly different across the four study groups. Post hoc analysis revealed that the genotoxicity observed in the sitagliptin group was significantly higher than that observed in the medical nutrition therapy group, but lower than that occurring in subjects who received thiazolidinediones. All of the three cytotoxicity endpoints were significantly lower in patients treated by oral anti-diabetic agents compared with those who received medical nutrition therapy. However, the three indexes did not differ significantly in the sitagliptin, rosiglitazone, and pioglitazone groups. Taken together, these pilot data indicate that sitagliptin and thiazolidinediones may exert genotoxic and cytotoxic effects in patients with type-2 diabetes. Further investigations are necessary to clarify the possible long-term differences between oral anti-diabetic drugs in terms of genotoxicity and cytotoxicity, and how these can modulate the risk of developing diabetic complications in general and cancer in particular.

The Effect of Regular Exercise and its Duration on Metabolic Parameters.

Regular exercise is crucial for regulating metabolic parameters. This retrospective study aimed to evaluate the effects of regular exercise duration on glycaemic and metabolic parameters, insulin resistance, and atherogenic indices in individuals attending a single-family health centre. A total of 403 individuals were divided into three groups based on their exercise status as Group A with no regular exercise, Group B with <150 minutes, and Group C with ≥150 minutes of regular excercise per week. The demographic and clinical data were collected from the subjects' records. The median age in Group A was significantly higher than in Group B and C, the median weight of Group A and B was significantly lower than in Group C, and high-density lipoprotein cholesterol level was significantly higher in Group B than in C. Type 2 diabetes percentage was significantly higher in Group C compared to B. Other glycaemic and metabolic parameters, insulin-resistance, and atherogenic indices were similar among the three groups. The results of this study indicated that subjects with higher weight, lower HDL levels, and Type 2 diabetes mellitus were those doing regular exercise in the advised duration per week.
