The effect of skeletal muscle area and attenuation in patients with sternum fracture due to blunt chest trauma.

OBJECTIVE: This study aims to retrospectively investigate the imaging features of patients with sternum fracture (SF) and concomitant organ injuries. We also aimed to evaluate the potential prognostic effect of skeletal muscle area (TMA) and muscle attenuation (MuA) values. PATIENTS AND METHODS: Computed tomography (CT) images of patients with SF were re-evaluated by two observers (Observer-1 and 2). Observer-3 has measured TMA and MuA values. Observer-1 has repeated the measurements blindly to the first measurement results to evaluate the inter-observer agreement. The length of hospital stay, death, hemiplegia, or quadriplegia were investigated from the archives. Mann-Whitney U-test or Student's t-test was used to investigate the relationship between linear variables. The intraclass correlation coefficient (ICC) score was used to evaluate the interobserver agreement. Logistic regression analysis was used to estimate the relative effect of variables by calculating unadjusted odds ratios (ORs) for categorical outcomes. RESULTS: Sixty-five patients had SF and 53 patients had SF and concomitant organ injuries. The most common injuries accompanying SF were rib fracture (73.58%) and lung contusion (60.38%). Manubrium fracture was the most common fracture location (52.3%), and 18 patients (27.7%) had displaced SF. Eight patients (15.1%) were discharged with plegia and five (9.4%) died. Hemothorax, displaced SF and decreased MuA were predictors of prolonged hospital stay, and the presence of cardiac contusion, displaced SF, hemothorax, and vertebra body fracture were independent factors for death. CONCLUSIONS: The presence of a displaced SF and decreased MuA value are important prognostic factors in patients with SF.

The impact of alternative donor types on viral infections in pediatric hematopoietic stem cell transplantation.

Viral infections remain one of the most important complications following allogeneic HSCT. Few reports compare virus infection between different donor types in pediatric patients. We retrospectively analyzed viral infections and the outcome of one hundred and seventy-one pediatric patients (median 7.38 years) who underwent allogeneic HSCT from matched related donor (MRD, n = 71), 10 of 10 HLA allele-matched unrelated donors (MUD1; n = 29), 9 of 10 HLA allele-matched unrelated donors (MUD2; n = 40), and haploidentical donors (n = 31). PCR screening for BK virus, adenovirus, Epstein-Barr virus, parvovirus B19, human herpesvirus 6, and CMV were performed routinely weekly. Infections between 0-30, 31-100, and 101 days-2 years were identified separately. BK virus and CMV reactivations were significantly low in MRD transplant patients (P = .046 and P < .0001, respectively), but incidences of all virus infections between MUD1, MUD2, and haplo-HSCT were found statistically not different. The OS was found to be affected by having one or multiple virus infection (P = .04 and P = .0008). Despite antiviral prophylaxis and treatments, post-transplant viral infections are associated with reduced overall survival. Haplo-HSCT is comparable with MUD transplantation in the setting of viral infections. A larger study group and prospective studies are needed to confirm this observation.

Is there any difference regarding atopy between children with familial Mediterranean fever and healthy controls?

Introduction: There are only a few studies regarding the prevalence of atopy in Familial Mediterranean fever (FMF) patients, and their results are conflicting. Methods: In this study children with the diagnosis of FMF were evaluated for the presence of atopy by comparing with controls. One hundred and eighteen children diagnosed as FMF and 50 healthy age and sex matched controls were enrolled. They were evaluated for the presence of rhinitis, atopic dermatitis, urticaria and asthma. Laboratory assessment was done by measuring IgA, IgM, IgG, IgE levels, total eosinophil count and by performing skin prick test (SPT) panels for common allergens to children with FMF and healthy controls. Results: One hundred and eighteen children (61girls and 57 boys) diagnosed as FMF with a median age of 120 ± 47 months (range 36-204 months) were compared with 50 healthy controls (31 girls and 19 boys) having a median age of 126±37 (range 48-192 months). The mean percentage of total eosinophil count of patients was similar to that of the control group. The mean level of IgE was significantly higher in children with FMF than controls (136 ± 268, 87 ± 201, respectively; p values < 0.05). The percentage of skin prick test positivity was similar for both patients and controls (13% and 8.2%, respectively; p > 0.05). The prevalences of atopic dermatitis, allergic rhinitis, and asthma in the patient group were 5.08%, 28.8%, and 15.25%, respectively, while the control group had the prevalences of 0%, 36%, and 14% respectively. Conclusion: Children with FMF did not show an increase of atopic dermatitis, allergic rhinitis and asthma with respect to controls (AU)

Fragmented QRS is associated with cirrhotic cardiomyopathy in patients with decompensated cirrhosis.

BACKGROUND AND AIM: It has been reported that the fragmented QRS (fQRS) is related to left ventricular systolic dysfunction and diastolic dysfunction. The aim of this study was to determine the frequency of fragmented QRS (fQRS) in patients with decompensated cirrhosis and to evaluate the relationship between the presence of fQRS and systolic and diastolic dysfunction. METHOD: PThe study included consecutive 189 patients with decompensated cirrhosis. fQRS pattern was described as presence of RSR' manifested as existence of additional R wave and notching in either R or S waves in ECG recordings. Conventional echocardiography and tissue doppler echocardiography were performed in all patients. RESULTS: The prevalence of fQRS was 31% (59/189) in patients with decompensated cirrhosis. The patients with fQRS had worse diastolic and systolic functions in comparison to the patients without fQRS. In addition, multivariate analysis revealed that the presence of an fQRS, Na levels < 125 mEq/L, the Child-Pugh score and the MELD score were independent predictive factors for mortality (respectively, p < 0.001, p < 0.001, p < 0.001 and p < 0.001). CONCLUSIONS: In conclusion,this study showed a relationship between the presence of an fQRS and cardiac dysfunction. In addition, the fQRS appeared to act as an independent predictor of mortality in patients with decompensated cirrhosis. These data suggest that the fQRS may represent a novel noninvasive marker for cardiac involvement and for predicting mortality in patients with decompensated cirrhosis.

Plasma Levels of Plasminogen Activator Inhibitor Type 1 and Vitronectin in Children With Cancer.

BACKGROUND: The plasminogen activator system controls intravascular fibrin deposition; besides, it also participates in a wide variety of physiologic and pathologic processes, including cancer. PROCEDURE: In this study, we examined the levels of plasminogen activator inhibitor 1 (PAI-1) and vitronectin in 32 newly diagnosed pediatric patients with malignancies, determined by enzyme-linked immunosorbent assay between January 2009 and January 2010 and compared them to 35 age-matched healthy children, using SPSS 16.0 software. RESULTS: The mean level of PAI-1 was 23.02 ± 15 (8.2-71.19) ng/mL and vitronectin was 83.10% ± 23.77% (12%-126%) in the tumor group. Thirty-five healthy children in the same age range were enrolled in the control group. The levels of PAI-1 and vitronectin were 23.63 ± 10.44 (11.67-58.85) ng/mL and 85% ± 20.85% (39%-126%), respectively. No significant difference was found between the 2 groups by independent sample t-test (P = .86 and P = .69). CONCLUSIONS: This is a preliminary study done in children with malignancies, investigating PAI-1 and vitronectin. Further study is needed, including larger trials and tumor tissue with histopathological examination as in adults.

Subclinical hypothyroidism in combination with vitamin D deficiency increases the risk of impaired left ventricular diastolic function.

OBJECTIVE: Subclinical hypothyroidism and vitamin D deficiency are common. The diastolic function of patients with both subclinical hypothyroidism and vitamin D deficiency remains unknown. This study aimed to investigate diastolic dysfunction in patients with both subclinical hypothyroidism and vitamin D deficiency. SUBJECTS AND METHODS: This study included 254 patients. All patients underwent standard Doppler echocardiography. Patients who had risk factors for diastolic dysfunction or had used L-thyroxine and vitamin D within the previous 3 months were excluded. Vitamin D deficiency was defined as a 25-OH-vitamin D level lower than 20 ng/ml, and vitamin D sufficiency was defined as a 25-OH-vitamin D level ≥ 30 ng/ml. Subclinical hypothyroidism was defined as a TSH level of 4.5-10 mU/l when the free T4 concentration was normal. RESULTS: The patients were divided into 4 groups. Group 1 (n=71) included patients with subclinical hypothyroidism and vitamin D deficiency; Group 2 (n=66) included patients with subclinical hypothyroidism and vitamin D sufficiency; Group 3 (n=65) included euthyroid patients with vitamin D deficiency; and Group 4 (n=52) included euthyroid patients with vitamin D sufficiency. LAVI (31.3 ± 3.2, 28.7 ± 3.0, 28.4 ± 3.4, and 27.9 ± 3.9; p<0.001) and E/E' values (11.2 ± 2.7, 8.9 ± 2.7, 9.1 ± 2.9, 8.8 ± 2.5; p<0.001) were significantly higher in Group 1 than in Groups 2, 3 and 4. E' values were significantly lower in Group 1 than in Groups 2, 3 and 4. CONCLUSION: The coexistence of subclinical hypothyroidism with vitamin D deficiency can lead to further deterioration in the LV diastolic function via the regulation of intracellular calcium and induction of inflammatory activity. Therefore, close follow-up of the diastolic functions of these patients could be beneficial.

Increased serum levels of GDF-15 associated with mortality and subclinical atherosclerosis in patients on maintenance hemodialysis.

BACKGROUND/AIMS: Increased carotid intima-media thickness (CIMT) was shown to be an independent predictor of cardiovascular (CV) mortality in dialysis patients and the general population. Growth differentiation factor 15 (GDF-15), a member of the transforming growth factor superfamily, is produced by cardiomyocytes and atherosclerotic lesions under stress conditions such as inflammation. We assessed associations between serum concentrations of GDF-15, mortality, and CIMT for subclinical atherosclerosis in hemodialysis (HD) patients. METHODS: A total of 87 patients on maintenance hemodialysis and 45 sex- and age-matched healthy controls were included in this prospective study. Serum GDF-15 levels were measured by ELISA. CIMT was assessed by Doppler ultrasonography. The association between serum GDF-15 levels and mortality was assessed using Cox regression analysis with serum levels categorized into two groups according to the median value (328.18 pg/ml). Patients were followed for 2 years and cause-specific and all-cause mortality were determined. RESULTS: The median level of serum GDF-15 was significantly higher in HD patients than controls [328 (198-522) vs. 176 (101-289) pg/ml, p < 0.01, respectively]. Serum GDF-15 levels were correlated to CIMT (r = 0.607, p < 0.001), C-reactive protein (CRP; r = 0.250, p = 0.010), HD duration (r = 0.376, p = 0.004), and serum albumin (r = - 0.156, p = 0.030). The multivariate analysis revealed that GDF-15 was found to be an independent variable of CIMT in HD patients. In the study, the serum GDF-15 level was an independent marker of all-cause of mortality when adjusted for age, CRP, and history of diabetes mellitus. CONCLUSION: The relationship between serum GDF-15, mortality, and carotid artery thickening suggests that GDF-15 may be a novel marker of atherosclerosis, inflammation, and malnutrition in HD patients.

Relationship of galectin-3 to left ventricular geometry and hypertrophy in chronic hemodialysis patients.

AIM AND BACKGROUND: Galectin-3 (Gal-3) is used to determine the prognosis of heart failure. Some studies revealed that Gal-3 promoted cardiac hypertrophy but there is no study in which the relationship between Gal-3 and left ventricular hypertrophy (LVH) geometry in patients without diastolic and systolic function impairment has been explored. The aim of the study was to analyze associations between plasma Gal-3 levels, LVH, and LV geometry in maintenance hemodialysis (HD) patients without systolic and diastolic dysfunction. PATIENTS AND METHODS: The study group included 105 patients (53 women and 52 men)--with an average age of 58.2 ± 12.6 years, treated with HD for an average of 45 ± 32 months--and 60 healthy controls. The Gal-3 and other biochemical parameters were measured and color Doppler echocardiography was performed. For this study LVH was considered present when the LV mass index (LVMI) exceeded 95 g/m(2) in women and 115 g/m(2) in men. Left ventricular geometry was classified into the four groups on the basis of left ventricular mass and relative wall thickness (RWT). RESULTS: Concentric hypertrophy (CH, 40.9 %, n = 43) was the commonest geometric pattern in our study. The Gal-3 levels in CH patients were not different from the patients with eccentric hypertrophy (EH). Plasma levels of Gal-3 correlated with LVMI (r = 0.617, p < 0.001), parathyroid hormone (PTH, r = 0.408, p < 0.001), uric acid (r = 0.281, p = 0.004), C-reactive protein (CRP, r = 0.412, p < 0.001), and RWT (r = 0.281, p = 0.004) but were inversely correlated with albumin (r = - 0.466, P < 0.001) in the whole group. Plasma levels of Gal-3 were associated with LVMI (r = 0.812, P < 0.001), RWT (r = 0.318, p = 0.001), and CRP(r = 0.381, p < 0.001) in maintenance hemodialysis patients. CONCLUSION: The Gal-3 level is related to left ventricular hypertrophy and it is independent of left ventricle geometry. The relationship between LVH and Gal-3 might be direct or it may also be inflammation-related.

Genotoxic effects of some antituberculosis drugs and mixtures in rats.

In this study*, it was aimed to observe, genotoxic effects of antituberculosis drugs and combinations on rats. Animals were treated with 31.5 mg/kg isoniazid (INH), 54 mg/kg rifampicin (RIF), 189 mg/kg pyrazinamide (PYR), 100 mg/kg etham-butol(ETA), INH+RIF+PYR (MIX1) and INH+RIF+PYR+ETA (MIX2) mixtures applied via gavage for 90 days. At the end of the study, blood, liver and kidney samples were taken and evaluated by Comet and Micronucleus techniques. Compared to control group, head intensity decreased, tail intensity and tail migration increased on experiment groups in blood samples. Head intensity of PYR and mixture groups decreased, tail intensity of PYR and mixture groups increased and tail migration of PYR, ETA and mixture groups increased in liver samples. Head intensity decreased and tail intensity increased of INH, RIF, ETA and MIX1 group; tail migration increased of MIX1 group in kidney samples. Compared to control group, micronucleus rate of ETA, RIF and MIX 2 groups increased in experiment groups. In conclusion antituberculosis drugs and their mixtures applied for 90 days causes to double strand break of DNA damage at different degrees in blood, kidney and liver cells in rats.

Increased levels of galectin-3 were associated with prediabetes and diabetes: new risk factor?

PURPOSE: Galectin-3 (Gal-3) is a marker of cardiac fibrosis and predicts incident heart failure. Gal-3-deficient mice are resistant to multiple low-dose streptozotocin-induced diabetes. Recent experimental studies suggested an important role for Gal-3 in the regulation of adiposity, metaflammation and type 2 diabetes. This study aimed to examine the relationship between Gal-3 and newly diagnosed prediabetes and diabetes. METHODS: Gal-3 concentrations were measured in 118 participants and 56 age- and sex-matched healthy controls. All subjects underwent a 75-g oral glucose tolerance test and were stratified into normal, prediabetic, and diabetes mellitus subgroups. DM was defined as a plasma glucose level ≥126 mg/dL in the fasting state or ≥200 mg/dL in the second hour after glucose loading. Impaired fasting glucose was defined as an FPG level of 100-125 mg/dL, and impaired glucose tolerance was defined as a 2-h plasma glucose level of 140-199 mg/dL. RESULTS: Sixty-one patients had prediabetes (Group 1), 57 had diabetes (Group 2), and 56 had neither diabetes nor prediabetes (Group 3). Gal-3 levels correlated with FPG (r = 0.787, P < 0.01), 2hPG (r = 0.833, P < 0.01), CRP (r = 0.501, P < 0.01), and HOMA-IR (r = 0.518, P < 0.01). Gal-3 levels were higher in Group 2 than in Groups 1 and 3 [1,053.9 (358.1) and 744.1 (119.3) vs. 481.7 (175.4) pg/mL; P < 0.001]. Gal-3 is an independent predictor of diabetes in multivariate logistic analysis. In ROC analysis, a Gal-3 cutoff value of 803.55 pg/mL diagnoses diabetes with a sensitivity of 80.7 % and a specificity of 85.5 % (AUC = 0.912). CONCLUSIONS: Gal-3 is a promising biomarker for detecting prediabetes and diabetes.

Prevalence of asthma, local risk factors and agreement between written and video questionnaires among Turkish adolescents

BACKGROUND: There is currently no standard tool for the measurement of asthma in epidemiological studies. The objectives of this study were to determine the prevalence of asthma, to describe the potential local risk factors, and to assess the agreement between written and video questionnaires in 13- to 14-year-old schoolchildren. METHODS: We performed a cross-sectional study involving 5427 adolescents in 26 schools. Prevalence of asthma symptoms were evaluated using the International Study of Asthma and Allergies in Childhood (ISAAC) written and video questionnaire. The adolescents were asked additional questions for risk factors of asthma. RESULTS: The prevalence of lifetime wheeze, wheeze in the last 12 months and doctor-diagnosed asthma with written questionnaire were found as 13.5%, 6.3% and 11.2% respectively. Prevalence of lifetime wheeze, wheeze in the last 12 months, wheeze after exercise in the last 12 months, with video questionnaire were found as 9.6%, 5.5%, 11.9% and 1.9% respectively. The proportion of total agreement between the two questionnaires was high (0.77-0.81) with poor kappa value (0.25-0.50). In multivariate analysis, family history of atopy, stuffed toys and accompaniment of children to their parents after school hours in textile industry were found as risk factors for asthma. In addition kind of bird, such as canary was found as a risk factor. CONCLUSION: Prevalence of asthma is moderate in Turkey. Agreement between the two questionnaires was high. Accompaniment of children to their parents in textile industry is a newly-described risk factor for asthma

Risk factors affecting asthma prevalence in adolescents living in Istanbul, Turkey

BACKGROUND: Asthma is one of the most important diseases of childhood. The aim of this study was to evaluate the prevalence of asthma symptoms and risk factors affecting asthma. METHODS: In a cross-sectional study design, 9991 children, aged 13-14 years in 61 primary schools in 32 districts of Istanbul were evaluated. Asthma prevalence among the children was assessed using the ISAAC protocol. RESULTS: In our study, a total of 10,894 questionnaires were distributed to 13-14 years old children, and of these 9991 questionnaires were suitable for analysis with an overall response rate of 91.7%. The rates of wheeze ever, wheezing in last 12 months and lifetime doctor diagnosed asthma prevalence were 17.4%, 9.0%, and 11.8%, respectively. There were 4746 boys (47.9%) and 5166 girls (52.1%) with M/F ratio of 0.92. Atopic family history, fewer than three siblings living at home, tonsillectomy or adenoidectomy history, consumption of fermented foods, mixed pickles, margarine and meat were found to be associated with an increased asthma risk. Use of paracetamol in the last 12 months, consumption of fruit and animal fats acted as a protective factor against asthma. The Mediterranean-style diet was not associated with the prevalence of asthma. CONCLUSIONS: Lifetime doctor diagnosed asthma prevalence was found to be 11.8% in 13-14 year olds. History of tonsillectomy and/or adenoidectomy and consumption of fermented foods, mixed pickles, margarine and meat may increase the symptoms of asthma. Usage of paracetamol and consumption of animal fats may be investigated as a protective factor against asthma

Asthma knowledge level of child daycare center teachers' in Istanbul, Turkey.

AIM: Teachers are primarily responsible for supervising schoolchildren with asthma during school hours. The purpose of this study was to elucidate the level of knowledge of child daycare center teachers about asthma and factors affecting their knowledge. METHODS: This study was performed on 297 teachers from 20 randomly selected child daycare centers in Istanbul. The teachers' level of knowledge about asthma was assessed by a questionnaire with 32 questions about asthma. The teachers were asked thirteen additional questions about demographic data and other characteristics of the child daycare centers and about themselves. One-way ANOVA and the independent samples t-test were used to determine differences in the level of asthma knowledge. RESULTS: A total of 297 teachers (287 females/10 males) filled in the questionnaire. The mean age of the teachers was 26.4 ± 8.1 years (range, 20-53 year). The teachers' "response score rate for each question" ranged from 38% to 94%. The teachers' "completely true response rate for each question" was lower and ranged from 1.6% to 83.9%. "The mean of asthma knowledge score" for the 32 questions was 113.64 ± 20.26 (71% ± 12.7%) from a maximum of 160 marks. "Asthma knowledge score for all questions" was related to teachers' gender, age, location and property of child daycare center and number of children in child daycare center. CONCLUSION: Although teachers of child daycare centers have some knowledge about asthma, their "completely true response rate for each question" was insufficient. Much more efficient educational programs are needed for these teachers.

The coexistence of renal cell carcinoma and diffuse large B-cell lymphoma with hypercalcemic crisis as the initial presentation.

INTRODUCTOIN: Severe hypercalcemia can be life threatening. The causes of hypercalcemia can be divided into seven categories: hyperparathyroidism, vitamin D-related causes, malignancy, medications, other endocrine disorders, genetic disorders, and miscellaneous causes. Evaluation of a patient with hypercalcemia should include a careful history and physical examination focusing on clinical manifestations of hypercalcemia, risk factors for malignancy, causative medications, and a family history of hypercalcemia-associated conditions (e.g. kidney stones). Hypercalcemia was clasified as serum levels of calcium: 1) mild hypercalcemia (calcium 14 mg/dl). We should keep in mind that severe hypercalcemia was originated from two or more causes. This is the first report in the literature; renal cell carcinoma (RCC) and diffuse large B-cell lymphoma (DLBCL) presented severe paraneoplastic hypercalcemia. CASE PRESENTATION: We report a case of a 63-year-old Turkish man with RCC and DLBCL who showed severe hypercalcemia (calcium=15.01 mg/dl) accompanied by elevation of serum parathyroid hormone-related protein (PTH-rP) as the initial presentation. While hypercalcemia is one of the complications of various types of cancerous diseases, it has not been reported still as the first presentation of the coexistence of RCC and DLBCL. After radical nephrectomy, the patient underwent six courses of chemotherapy consisting of rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisolone and achieved a complete remission that lasts 2 years. CONLUSION: This case report describes a patient with two different malignancies (RCC and DLBCL) with the unusual presentation of hypercalcemia. We review the differential diagnosis and treatment of malignant hypercalcemia. We suggest that coexistence of DLBCL with RCC, although rare, should be considered as a possible causative in hypercalcemia of unknown underlying disease.

Neutrophil-lymphocyte ratio may be superior to C-reactive protein for predicting the occurrence of postmenopausal osteoporosis.

OBJECTIVE: Recent studies revealed that inflammation plays a critical role in bone remodeling and the pathogenesis of postmenopausal osteoporosis, a major health concern. Neutrophil-lymphocyte ratio (NLR) is a cost-effective marker of inflammation that has been linked with several diseases. This study aimed to compare NLR and C-reactive protein (CRP) levels in osteopenic, osteoporotic, and control subjects and to assess the correlation between NLR levels, CRP, and bone mineral density (BMD) in postmenopausal women. METHODS: In this cross-sectional study, the relationship between NLR, CRP, and BMD in 438 women was investigated using uni- and multivariate analyses. BMD (g/cm²) was measured by dual-energy X-ray absorptiometry (DEXA) at the lumbar spine and femur. Complete blood count (CBC), CRP, glucose/lipid metabolism, and established risk factors were determined. RESULTS: In the osteoporotic group, NLR and CRP levels were found to be elevated as compared to the osteopenic and control groups (NLR: 4.68 ± 0.72, 3.17 ± 0.43, 2.01 ± 0.54; CRP: 12.3 ± 4.1, 4.1 ± 2.7, 3.2 ± 2.1, respectively). A negative correlation was present between NLR and the lumbar spine (L2-L4) and femoral neck BMD after adjusting other risk factors. There was no correlation between CRP levels and BMD after adjusting other risk factors. NLR was significantly associated with L2-L4 BMD (ß = -0.653, p<0.001) and femoral neck BMD (ß = -0.178, p<0.001), but CRP level had no association with BMD in a multivariate model. CONCLUSIONS: Our data indicate that NLR may be a better predictor than CRP for occurrence of osteoporosis in postmenopausal women.

Benefits of the neutrophil-to-lymphocyte ratio for the prediction of gestational diabetes mellitus in pregnant women.

AIMS: There is growing consensus in the literature that inflammation plays a central role in the pathophysiology of obesity, Type 2 Diabetes Mellitus (T2DM), Gestational Diabetes Mellitus (GDM) and cardiovascular complications. Measuring the neutrophil-to-lymphocyte ratio (NLR) provides a simple inexpensive method for the assessment of inflammatory status. We investigated the predictive value of pre-procedural (before the oral glucose tolerance test (OGTT)) NLR on the development of GDM in pregnancy. METHODS: 42 women with GDM and 68 women without GDM were included in the study. Complete Blood Count and biochemical tests were followed by a diagnostic 4-point 100-g-OGTT within 2 weeks. GDM was diagnosed by the Carpenter and Coustan criteria. The NLR was calculated from the data. RESULTS: The mean NLR level was significantly higher in GDM women (3.00±0.83 vs. 2.26±0.43 p<0.001, respectively). In ROC analysis, NLR>2.93 had 76.2% sensitivity and 94.1% specificity in predicting GDM. Logistic regression analysis showed that elevated NLR (OR: 5.512, 95% CI: 1.352-22.475, p=0.017) was an independent variable for predicting GDM in pregnancy. CONCLUSIONS: An elevated NLR level is a powerful and independent predictor of GDM. The results of this study suggested that inflammation plays a central role in the pathogenesis of GDM.

History of tonsillectomy and/or adenoidectomy and consumption of fermented foods, mixed pickles, margarine and meat may increase the symptoms of asthma. Usage of paracetamol and consumption of animal fats may be investigated as a protective factor against asthma.

RESULTS: The prevalence of lifetime wheeze, wheeze in the last 12 months and doctor-diagnosed asthma with written questionnaire were found as 13.5%, 6.3% and 11.2% respectively. Prevalence of lifetime wheeze, wheeze in the last 12 months, wheeze after exercise in the last 12 months, with video questionnaire were found as 9.6%, 5.5%, 11.9% and 1.9% respectively. The proportion of total agreement between the two questionnaires was high (0.77-0.81) with poor kappa value (0.25-0.50). In multivariate analysis, family history of atopy, stuffed toys and accompaniment of children to their parents after school hours in textile industry were found as risk factors for asthma. In addition kind of bird, such as canary was found as a risk factor. CONCLUSION: Prevalence of asthma is moderate in Turkey. Agreement between the two questionnaires was high. Accompaniment of children to their parents in textile industry is a newly-described risk factor for asthma.

Increased epicardial fat tissue is a marker of subclinical atherosclerosis in patients with psoriasis.

BACKGROUND: Carotid intima-media thickness (CIMT) is a potential indicator of subclinical atherosclerosis in patients with psoriasis. Epicardial fat thickness (EFT) is proposed as a new cardiometabolic risk factor. OBJECTIVE: To evaluate the association between EFT and CIMT in patients with psoriasis. METHODS: This was a cross-sectional and observational study; 65 patients with psoriasis and 50 age- and sex- matched control subjects were included. Data about echocardiographic EFT, CIMT, anthropometric measurements and metabolic profile were obtained. RESULTS: The EFT and CIMT were significantly increased (7.3 ± 0.5 vs. 6.5 ± 0.5 mm, P < 0.01; 0.74 ± 0.11 vs. 0.60 ± 0.07 mm, P < 0.01, respectively) in patients with psoriasis compared with the controls. EFT was significantly correlated with CIMT (r = 0.69, P < 0.01). In a multiple linear regression model in which EFT was independently associated with psoriasis (ß = 0.45, P < 0.01), age (ß = 0.33, P = 0.01), CIMT (ß = 0.50, P < 0.01), body mass index (ß = 0.25, P = 0.01), high-sensitivity C-reactive protein (ß = 0.32, P < 0.01) and duration of disease (ß = 0.34, P = 0.03). CONCLUSIONS: We demonstrated that EFT and CIMT are increased in patients with psoriasis, and that echocardiographic EFT is closely correlated with CIMT in patients with psoriasis. The echocardiographic assessment of EFT may have the potential to be a simple marker of subclinical atherosclerosis and increased cardiovascular risk in patients with psoriasis.
