RESUMO
Diabetes is a major risk factor for cardiovascular disease. Despite recommendations and available therapeutic options, patients with diabetes do not always reach the recommended lipid levels. In this study, our aim was to compare the real world lipid profile of type 2 diabetes patients with guideline recommendations for dyslipidemia. Four hundred and sixty eight consecutive patients referred to Outpatient Diabetes Clinic of Istanbul Medeniyet University were recruited. Patient anthropometric measurements (height, weight, waist circumference), biochemical test results (LDL cholesterol (LDL-c), triglycerides, HDL cholesterol, HbA1c) and treatment modalities were recorded. Patients were stratified into cardiovascular risk categories according to the risk factors and their treatment dose was compared to the recommendations. Among 468 patients, 56 (12%) patients had coronary heart disease (CHD). Thirty-four percent of these patients were not on statin treatment (n=19) and their mean LDL-c level was 114±29 mg/dL (2.9±0.75 mmol/L). Nineteen percent of these patients were on high intensity statin treatment (atorvastatin 40-80 mg, rosuvastatin 20 mg). Only four patients with CHD had LDL-c levels <70 mg/dL (1.8 mmol/L). Four hundred and twelve patients had no CHD. In these patients, the mean LDL-c level was 132±38 mg/dL (3.4±0.9 mmol/L). Eighty (19%) patients had LDL-c level lower than 100 mg/dL (2.5 mmol/L). Overall 82% (n=384) of the cohort had not achieved treatment goal. In conclusion, a more pronounced approach for statin treatment is needed in diabetes patients for both primary and secondary prevention of cardiovascular diseases.

BACKGROUND: Celiac disease (CD) is an enteropathy characterized with immune reaction to gliadin protein. AIM: In this study, we aimed to assess effect of CD on coronary microvascular circulation and the association between coronary flow velocity reserve (CFVR) and hs-CRP/Albumin ratio. MATERIAL AND METHODS: Study was conducted between March 2017 and November 2018 with CD at Umraniye Training and Research Hospital Gastroenterology Clinic. CFVR was defined as the ratio of hyperemic to baseline diastolic peak velocities. CFVR ≥ 2.0 was considered normal. C-reactive protein/albumin ratio (CAR) was calculated as hs-CRP/albumin. RESULTS: Serum albumin (4.27 ± 0.56 vs 4.50 ± 0.34; P value: .04) level was significantly lower in celiac group but higher Hs-CRP (2.44 ± 1.24 vs 1.82 ± 1.29; P value < .01), hs-CRP/albumin ratio (0.57 ± 0.30 vs 0.41 ± 0.31; P value: .03) were recorded in celiac group. Both hyperemic flow and CFVR substantially lower in the celiac group compared to controls. In univariate analysis; age, hs-CRP, and hs-CRP/albumin ratio were associated with low CFVR and hs-CRP/albumin level was an accurate predictor of low CFVR at the ROC curve. CONCLUSION: In this study, we found that in patients with CD, coronary flow reserve is impaired.

Background/aim: Studies have shown an increased depression rate in patients with type 2 diabetes mellitus (T2DM) compared to the normal population. It is now acknowledged that patients suffer from distress rather than depression. Our aim was to validate the Turkish version of the Diabetes Distress Scale (DDS) and to show distress levels of the participants. Materials and methods: The scale was translated from English to Turkish by the authors and translated back to English. Between August 2015 and January 2016 all the patients who were referred to the T2DM Clinic of Istanbul Medeniyet University were screened, and eligible patients were recruited. For calculating internal consistency Cronbach's alpha coefficient was used. Results: A total of 205 patients [120 females (58.5%), 85 males (41.5%)] were included. Cronbach's alpha coefficient was 0.874, showing internal consistency. The Spearman Brown correlation coefficient was calculated between the first 9 and second 8 questions as 0.884. Thetotal variances were explained at a level of 66.2% with 4 factors. Sixty-three patients (30%) had a score of ≥3, indicating diabetic distress. Correlation analysis showed a significant correlation between total score and HbA1c levels (r = 0.152 and P = 0.038). Conclusion: The Turkish version of the DDS for type 2 diabetes is a reliable tool for assessment of distress levels.

Background/aim: Leptin, ghrelin, and glucagon-like peptide-1 (GLP-1) affect hunger, satiety feelings, and food intake. We hypothesized that during Ramadan, if the brain knows that the body will be hungry until sunset, there may be differences between leptin, ghrelin, and GLP-1 levels in Ramadan and non-Ramadan fasting. Materials and methods: This study had two phases. In the first phase, the participants were asked to skip the dawn meal of Ramadan (suhur), so that 12 h of fasting could be achieved. Participants ceased food intake at midnight, and at noon blood was drawn. Eight participants were selected as a subgroup. These participants gave blood three times a day to detect hormonal changes during Ramadan. Six months later, in the second phase, blood samples were obtained at noon from participants after 12 h of fasting. Results: Analysis was conducted on 30 patients [19 males (63.3%) and 11 females (36.7%)]. There was a significant difference in leptin, ghrelin, and GLP-1 levels between Ramadan fasting and non-Ramadan fasting (P = 0.04, P = 0.02, and P < 0.001, respectively). In the subgroup analysis, there was no statistically significant difference in leptin, ghrelin, and GLP-1 levels over time. Conclusion: The results of this study suggest that the nervous and gastrointestinal systems may behave differently in religious fasting than in nonreligious fasting.
RESUMO
Growing data show the association of metabolic syndrome (MetS) or its components with cancer development and cancer-related mortality. It is suggested that in MetS and cancer association, insulin resistance and insulin-like growth factor 1 system play a key role, especially adipokines secreted from visceral adipocytes, free fatty acids and aromatase activity contribute to this process. It is also reported that MetS has a link with colorectal, breast, endometrial, pancreas, primary liver and, although controversial, prostate cancer. Although every component of MetS is known to have an association with cancer development, it is still debated whether the effects of these components are additive or synergistic. On the other hand, in the association between MetS and cancer, the role of antidiabetic and antihypertensive treatments including thiazolidinedione, insulin, angiotensin receptor blockers is also suggested. The primary approach in MetS-cancer relation is to prevent risk factors. Life style changes including weight loss and a healthy diet are known to decrease cancer risk in normal population. It is postulated that an insulin-sensitizing agent, metformin, has cancer-preventing effects on diabetic patients. This review discusses the relationship between MetS and cancer from different aspects and examines this relationship in some of the cancers suggested to be linked with MetS.

There are limited data on individual risk factors for SARS-CoV-2 infection (including unrecognized infection). In this seroepidemiologic substudy of an ongoing prospective cohort study of community-dwelling adults, participants were thoroughly characterized pre-pandemic. The SARS-CoV-2 infection was ascertained by serology. Among 8,719 participants from 11 high-, middle-, and low-income countries, 3,009 (35%) were seropositive for SARS-CoV-2. Characteristics independently associated with seropositivity were younger age (odds ratio, OR; 95% confidence interval, CI, per five-year increase: 0.95; 0.91-0.98) and body mass index >25 kg/m2 (OR, 95% CI: 1.16, 1.01-1.34). Smoking (as compared with never smoking, OR, 95% CI: 0.83, 0.70-0.97) and COVID-19 vaccination (OR, 95% CI: 0.70, 0.60-0.82) were associated with a reduced risk of seropositivity. Among seropositive participants, 83% were unaware of having been infected with SARS-CoV-2. Seropositivity and a lack of awareness of infection were more common in lower-income countries. The COVID-19 vaccination reduces the risk of SARS-CoV-2 infection (including recognized and unrecognized infections). Overweight or obesity is an independent risk factor for SARS-CoV-2 infection. Infection and lack of infection awareness are more common in lower-income countries.IMPORTANCEIn this large, international study, evidence of SARS-CoV-2 infection was obtained by testing blood specimens from 8,719 community-dwelling adults from 11 countries. The key findings are that (i) the large majority (83%) of community-dwelling adults from several high-, middle-, and low-income countries with blood test evidence of SARS-CoV-2 infection were unaware of this infection-especially in lower-income countries; and (ii) overweight/obesity predisposes to SARS-CoV-2 infection, while COVID-19 vaccination is associated with a reduced risk of SARS-CoV-2 infection. These observations are not attributable to other individual characteristics, highlighting the importance of the COVID-19 vaccination to prevent not only severe infection but possibly any infection. Further research is needed to understand the mechanisms by which overweight/obesity might increase the risk of SARS-CoV-2 infection.

PURPOSE: Acromegaly is characterized by bone changes due to excessive growth hormone (GH) secretion. Hyperostosis frontalis interna (HFI) is described as an overgrowth in the inner plate of the frontal bone. An increased incidence of HFI has been reported in patients with acromegaly. Since the etiology of HFI is poorly understood, we have analyzed whether there is a relationship between the hormonal and metabolic status of patients with acromegaly (with or without hyperprolactinemia) and the pathogenesis of HFI. METHODS: Forty-five patients with acromegaly and two control groups consisting of 25 patients with prolactinoma (group 1) and 47 healthy subjects (group 2) were included in this retrospective study. Baseline hormonal data and cranial imaging were obtained from medical records and analyzed. RESULTS: Mean frontal bone thickness was 6.75 mm in acromegaly, 4.85 mm in group 1, and 5.1 mm in group 2 of controls (p < 0.001). The frequency of HFI was higher in acromegalic patients than in the controls (22%, 0%, and 2.2%, respectively). There was no difference between the HFI positive and negative acromegalic patients in basal GH, IGF-1, and PRL levels, IGF-1 index, diagnosis lag time, and insulin resistance. There was no difference between groups regarding parietal and occipital bone thickness. CONCLUSION: Although the frequency of HFI is 22% in patients with acromegaly, neither excess GH nor hyperprolactinemia plays a role in its etiopathogenesis. Various genetic or epigenetic factors may contribute to its etiology.

Maneb is a widely used agricultural fungicide, which can lead to parkinsonism due to its neurotoxic effects on the dopaminergic system after chronic low-dose exposure. Previous acute human maneb poisoning cases occurred with low-dose maneb exposure through the dermal route causing renal failure. This report presents a case of acute renal failure and delayed paralysis due to ingestion of a large dose of maneb for a suicide attempt. A 16-year-old female patient was admitted to the emergency room because of drinking almost a whole bottle of maneb (400 mL [2 g L-1]) about 2 hours before. The patient was transferred to the intensive care unit with severe metabolic acidosis and renal failure. On the 4th day in intensive care unit, although the severe acidosis was resolved with haemodialysis, the patient was intubated because of ascending muscle weakness and dyspnoea. After staying in the intensive care unit for 9 days and in the nephrology ward for 2 weeks, the patient was discharged well from the hospital with no further need for haemodialysis but a persistent bilateral drop foot. One year after the event, renal functions were normal, and motor function in the lower extremities improved entirely.
RESUMO
Obesity has become an epidemic and a worldwide problem and its treatment is ever-evolving. Apart from diet and exercise, medication and surgery are other options. After disappointing side effects of various obesity drugs, new treatments showed promising results. This review discusses the following anti-obesity drugs: liraglutide, semaglutide, tirzepatide, orlistat, as well as the phentermine/topiramate and bupropion/naltrexone combinations. These drugs have been approved by the Food and Drug Administration (FDA) for weight reduction except for tirzepatide which is still under evaluation. Efficacy and tolerable safety profiles of some of these drugs contribute to the management of obesity and reduce the complications associated with this chronic disease.
RESUMO
BACKGROUND: The risk of cardiovascular disease is correlated with the frequency and control of associated risk factors in diabetes mellitus and may vary according to country. We evaluated risk factors for cardiovascular disease, cardiovascular events, and the use of preventive medications in patients with diabetes mellitus using the Prospective Urban and Rural Epidemiological Türkiye cohort. METHODS: Patients with diabetes mellitus versus without diabetes mellitus were compared for risk factors, cardioprotective drugs (angiotensin-converting enzyme inhibitors or angiotensin-II receptor antagonists, statins, and antiplatelets), and cardiovascular events. The primary outcome was major cardiovascular events (composite of cardiovascular death, myocardial infarction, stroke, or heart failure). RESULTS: Among 4041 participants, 549 (13.6%) had diabetes mellitus. The mean age (54.8 ± 8.4 vs. 49.3 ± 9.0 years, P <.001) and proportion of women (65.4% vs. 59.9%, P =.014) were higher in diabetics compared with non-diabetics. Hypertension, history of coronary heart disease, and use of statin, antiplatelets, and angiotensin-converting enzyme inhibitors or angiotensin-II receptor antagonists were more common in diabetics; however, the use of these medications at baseline was lower than optimal even in patients with diabetes mellitus and concomitant coronary heart disease (statin 31.2%, antiplatelets 46.9%, and angiotensin-converting enzyme inhibitors or angiotensin-II receptor antagonists 54.7%). During 11.5 years of follow-up, major cardiovascular events occurred in 288 (7.1%) patients, and the risk was higher in diabetics [hazard ratio (95% confidence interval) 1.71 (1.30-2.24); P <.001]. The increase in the risk of future events was comparable for those with diabetes mellitus alone without cardiovascular disease [hazard ratio 1.62 (1.20-2.20)] versus those with cardiovascular disease alone without diabetes mellitus [hazard ratio 1.31 (0.83-2.07)] and was additive in those with both conditions [hazard ratio 2.79 (1.65-4.69)]. The risk of major coronary events (myocardial infarction, angina, percutaneous, or surgical coronary intervention) was also higher in diabetes mellitus [hazard ratio 1.64 (1.26-2.15); P <.001]. CONCLUSION: Patients with diabetes mellitus have a higher risk of major cardiovascular events, and the risk is comparable to that observed in those with cardiovascular disease but no diabetes mellitus. The use of preventive medicines for cardiovascular diseases is disturbingly low in diabetics.

BACKGROUND: Male prolactinoma treatment by dopamine agonists (DA) restores sexual function. However, excessive DA dose can lead to impulse control disorder. OBJECTIVES: The aim of this retrospective study was to determine the level of testosterone that eliminates symptoms and provides fertility in male macroprolactinoma, without causing these adverse effects. MATERIALS AND METHODS: Twenty-seven male patients with macroprolactinoma were included. There were 16 macro (≥1-2.8cm), 7 large macro (≥2.9-3.9cm) and 4 giant (≥4cm) adenomas. Prolactin (PRL) and testosterone (T) levels were evaluated. A timeline was created to analyze improvement in symptoms of hypogonadism and infertility. Testosterone levels were compared with age-matched controls. RESULTS: Mean PRL, basal tumor diameter and shrinkage were 2846±3415ng/mL, 27.2±10.2mm and 63.4%, respectively. Basal T levels were 1.6±1.0ng/mL for patients and 4.4±1.5ng/mL for controls (P<0.001). Mean T level in the asymptomatic period was significantly lower than in controls (3.2±0.4ng/mL vs. 4.4±1.5ng/mL, respectively; P=0.002), while mean PRL was 27.2ng/mL. Fertility was achieved in 6 of the patients seeking fertility, and there was no difference in T level between these patients and controls (3.7±0.8ng/mL and 4.4±1.5ng/mL, respectively; P=0.14); when fertility was achieved, mean PRL was 26.9±23ng/mL. CONCLUSION: Patients should be carefully questioned regarding complaints at each consultation, and DA dose should not be increased unnecessarily, to avoid possible serious adverse effects.

Objectives: This study aims to determine whether COVID-19 patients with different initial reverse transcriptase-polymerase chain reaction (RT-PCR), computed tomography (CT) and laboratory findings have different clinical outcomes. Materials and Methods: In this multi-center retrospective cohort study, 895 hospitalized patients with the diagnosis of COVID-19 were included. According to the RT-PCR positivity and presence of CT findings, the patients were divided into four groups. These groups were compared in terms of mortality and need for intensive care unit (ICU). According to the COVID-19 Reporting and Data System (CO-RADS), all patients' CT images were staged. Multivariate binary logistic regression analysis was used to examine the relationship between CO-RADS and predictive inflammation and coagulation parameters. Results: RT-PCR test positivity was 51.5%, the CT finding was 70.7%, and 49.7% of the patients were in the CO-RADS 5 stage. The need for ICU and mortality rates was higher in the group with only CT findings compared to the group with only RT-PCR positivity, (14.9% vs. 4.0%, p < 0.001; 9.3% vs. 3.3%, p > 0.05; respectively). Mortality was 3.27 times higher in patients with CO-RADS 4 compared to those with CO-RADS 1-2. Being in the CO-RADS 4 stage and LDH were discovered to be the most efficient parameters in determining mortality risk. Conclusion: Performing only the RT-PCR test in the initial evaluation of patients in SARS-CoV-2 infection may lead to overlooking groups that are more at risk for severe disease. The use of a chest CT to perform CO-RADS staging would be beneficial in terms of providing both diagnostic and prognostic information.
RESUMO
OBJECTIVE: The Prospective Urban Rural Epidemiology (PURE) study is a prospective cohort study that collects data on social, environmental, and individual risk factors and chronic diseases among residents of 25 countries in the range of 35 to 70 years of age, living in rural and urban areas. The PURE study is directed by the Population Health Research Institute of McMaster University in Canada. In Turkey, the study is conducted by the Metabolic Syndrome Society. METHODS: In Turkey, the study is being conducted in 8 cities. The initial fieldwork began in 2008. Questionnaires were completed, and anthropometric measurements, blood and urine samples, handgrip strength evaluations, electrocardiogram readings, and spirometer and body composition measurements were obtained. Each year, participants were followed up via telephone. Every third year, questionnaires, field measurements, and biological data sampling were repeated. RESULTS: PURE Turkey has 4056 participants (female: 60.7%, male: 39.3%; mean age: 50±9.1 years). Among them, 43.9% had metabolic syndrome and 52.8% were obese. The prevalence of hypertension was 41.1% and proportion of controlled hypertension was 34%. A total of 2098 (51.7%) of the participants had a total cholesterol of ≥200 mg/dL or were using a lipid lowering agent. In patients with diabetes, 79.8% had low-density lipoprotein cholesterol levels ≥100 mg/dL. Although a dramatic change was not observed in those parameters in the follow-up years, the prevalence of diabetes mellitus increased from 13.7% in 2008 to 21% in 2015. The baseline and follow-up data of the PURE study were analyzed with the other countries participating in the study and reported for international publication. CONCLUSION: The PURE study is a large, ongoing, prospective epidemiological study that is investigating the "causes of the causes" of noncommunicable diseases in the world. In addition to revealing the health status of nations, the study also has the potential to affect health politics.

BACKGROUND AND AIMS: Obstructive sleep apnea syndrome (OSA) is an independent risk factor for endothelial dysfunction and cardiometabolic diseases. Plasma endocan levels are elevated in a large number of diseases, and is a novel surrogate endothelial cell dysfunction marker. We aimed to assess the role of serum endocan level as a potential mechanism of endothelial dysfunction in OSA patients. MATERIALS AND METHODS: This was a cohort study in which patients who had undergone a sleep study for diagnosis of OSA were recruited. Included patients were grouped according to apnea-hypopnea index (AHI) as mild, moderate and severe OSA. Patients with AHI < 5 served as control group. Endothelial function was evaluated with flow-mediated dilatation (FMD). Plasma endocan level was measured for all patients. RESULTS: One hundred twenty eight OSA patients included (15 controls, 22 with mild, 22 with moderate and 69 with severe OSA). The mean age was 51.6 ± 11.9 years and 43.8% (56/128) of the study population was female. As expected, the prevalence of hypertension, diabetes and cardiovascular disease increased as the severity of OSA increased. Endocan levels were significantly higher and FMD measurements were lower in patients with OSA compared to healthy controls. There was a positive correlation between AHI and serum endocan levels (rho = 0.826, P < 0.0001) and there was a negative correlation between AHI and FMD (rho = -0.686, P < 0.0001) In addition, we observed a strong negative correlation between serum endocan level and FMD (rho = -0.613, P < 0.0001). In linear regression analysis AHI was independently related both with endocan (P < 0.0001) and FMD (P = 0.011). CONCLUSION: Serum endocan level is strongly associated with the severity of OSA and endothelial dysfunction. Endocan might be a useful early novel marker for premature vascular endothelial system damage in OSA patients.

High lipid levels play important roles in the pathogenesis of atherosclerosis and some authors suggest vitamin D deficiency as a risk factor for atherosclerosis. The aim of this study was to evaluate the effect of vitamin D status on lipid profile in premenopausal women. PATIENTS AND METHODS: A total of 315 nonsmoking premenopausal female volunteers without diabetes mellitus were included in the study. Patients were divided into four subgroups. The groups were as follows: patients with less than or equal to 12 ng/ml (group 1, n=126) vitamin D levels, between 20 and 12 ng/ml (group 2, n=48), between 30 and 20 ng/ml (group 3, n=21), and at least 30 ng/ml (group 4, n=120) vitamin D levels. Total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), triglyceride (TG), and non-HDL-C levels of the four groups were compared. RESULTS: HDL-C levels of group 4 were the highest (P=0.03), and TG and non-HDL-C levels of group 1 were the highest (P=0.04, 0.016, respectively) in all groups. There was no significant difference between serum parathormone, calcium, and phosphorus levels of the four groups (P=0.778, 0.121, 0.184, respectively). In unadjusted analysis, 25-hydroxy vitamin D levels were found to be correlated negatively with BMI (P=0.0005), LDL-C (P=0.01), and non-HDL-C (P=0.003) and correlated positively with HDL-C levels (P=0.006). After adjustments for age, sex, BMI, and log parathormone levels were made, no correlation was found between 25-hydroxy vitamin D and lipid (TC, LDL-C, HDL-C, and TG) levels (P=0.91, 0.06, 0.95, 0.79, respectively). CONCLUSION: There may be an association between vitamin D insufficiency and dyslipidemia. However, this association may depend on obesity.
RESUMO
BACKGROUND: Gestational diabetes mellitus (GDM) is a prediabetic state that is known to increase the risk of cardiovascular diseases. We have investigated coronary flow velocity reserve (CFVR) and epicardial fat thickness (EFT), and left ventricular diastolic function in patients with a history of previous GDM (p-GDM). METHODS: Ninety-three women with GDM history and 95 healthy women without GDM history were recruited. We used transthoracic Doppler echocardiography to assess CFVR, EFT, and left ventricular diastolic function. Insulin resistance of each subject was assessed with homeostasis model assessment insulin resistance (HOMA-IR). Hemoglobin A1c and high-sensitivity C-reactive protein (hsCRP) were also measured in all patients. RESULTS: CFVR values were significantly lower (2.34 ± 0.39 versus 2.80 ± 0.24, p < 0.001) and EFT values were significantly higher in patients with p-GDM than the control group (5.5 ± 1.3 versus 4.3 ± 1.1, p < 0.001). E/E' ratio (7.21 ± 1.77 versus 6.53 ± 1.38, p = 0.003), hemoglobin A1c (5.2 ± 0.4 and 5.0 ± 0.3, p = 0.001), HOMA-IR (2.8 ± 1.4 versus 1.7 ± 0.9, p = 0.04), and hsCRP levels were significantly higher in the p-GDM group than the control group. Multivariate analysis revealed that gestational diabetes history is independently associated with CFVR. CONCLUSION: Women with a GDM history may be at more risk regarding coronary microvascular dysfunction compared to the healthy ones.
