Are Mean Platelet Volume and Neutrophil-to- Lymphocyte Ratio Valuable in The Early Detection of System Involvements in Henoch-Schönlein Purpura?

Aim:Henoch-Schönlein purpura (HSP) is the most common type of vasculitis in childhood, and severe complications due to intestinal and renal involvement can be observed. In this study, it was planned to investigate the value of mean platelet volume (MPV) and neutrophil-tolymphocyte ratio (NLR) in early detection of system involvement in HSP.Methods:A total of 119 patients diagnosed with HSP and 75 healthy controls were included in the study. Data on age, gender and physical examination as well as complete blood count, complete urine examination and faecal occult blood test were obtained from the files of the patients.Results:Gastrointestinal system (GIS) involvement was detected in 41 patients (34.45%), renal involvement in 35 patients (29.41%) and arthritis was detected in 21 patients (17.65%). It was determined that the mean hemoglobin (p=0.02) and MPV values (p=0.0001) o were significantly lower and the mean leukocyte (p=0.0001), platelet (p=0.0001), neutrophil (p=0.0001) count and NLR value (p=0.0001) were significantly higher in patients than in controls. No statistically significant difference was observed in the MPV and NLR values between patients with and without GIS involvement, renal involvement and arthritis.Conclusion:It is thought that MPV and NLR cannot be used as laboratory parameters in the early detection of system involvement in HSP

The Assessment of the Neutrophil-lymphocyte Ratio and Platelet-lymphocyte Ratio in Dyslipidemic Obese Children

Objective:Childhood obesity is one of the most important children’s health problems that is gradually increasing all over the world. Dyslipidemia which coexists with obesity is a risk factor for atherosclerotic diseases in adulthood. In this study, the usability of the neutrophil-lymphocyte ratio (NLR) and the platelet-lymphocyte ratio (PLR) in predicting dyslipidemia, a serious complication of obesity, in children were investigated.Method:Two hundred and seven cases aged between 11-17 years who were diagnosed with obesity at the Pediatrics Clinic of our hospital and 50 cases with no disorders whose complete blood count was performed for routine purposes were retrospectively investigated. The genders, ages, and examination findings of the cases were recorded. In obese children, leukocyte, hemoglobin, platelet, mean platelet volume, neutrophil and lymphocyte levels were evaluated in the complete blood count performed at the first admission. The NLR and the PLR were calculated. Preprandial blood glucose and preprandial insulin, serum aminotransferase values, and the lipid profile were recorded.Results:While dyslipidemia was determined in 99 (47.82%) of 207 cases who were diagnosed with obesity, it was not determined in 108 (52.18%) cases. The systolic blood pressure, diastolic blood pressure, and preprandial insulin level were higher in cases with dyslipidemia than the group without dyslipidemia. The PLR average of the dyslipidemic group was 112.75±39.11, the PLR average of the non-dyslipidemic group was 104.78±31.38, and the PLR average of the control group was 110.20±39.35, and there was no statistically significant difference between the PLR averages of the groups (p=0.353). The NLR average was 1.52±0.69 in the dyslipidemic group, 1.66±0.81 in the non-dyslipidemic group, and 1.72±1.26 in the control group. No statistically significant difference was observed between the NLR averages of all three groups (p=0.295).Conclusion:In this study, no relationship was determined between the PLR and NLR and dyslipidemia in obese children

Türkiye’nin yaşam memnuniyetine mekansal etkinin analizi

Mekansal veri analizi, analiz sonuçları nesnelerin ya da analiz edilen olayların konumlarına bağlı olan, hem konum bilgisi hem de nesnelerin özelliklerinin kullanımı gerektiren yöntemlerden oluşmaktadır. Coğrafi Bilgi Sistemlerinde meydana gelen ilerlemeler ve verinin analiz edilmesine yönelik programların geliştirilmesi mekansal veri analizde kullanılan yöntemleri daha uygulanabilir hale getirmiştir. Mekansal veri analizinde mekansal etkileşim ön plana çıkmakta ve mekansal etkileşim hem mekansal bağımlılığı hem de mekansal heterojenliği kapsamaktadır. Mekansal bağımlılık veya mekansal otokorelasyon bir mekanda ya da bölgede gözlenen değerlerin komşu gözlem değerlerine bağlı olduğu durumu yansıtmaktadır. Konumun ve konumlar arasındaki etkileşimin önemli olduğu çalışmalarda bu bağımlılık yapısını dikkate alarak geliştirilmiş yöntemlerin kullanılması gerekmektedir. Mekansal analizde kullanılan en yaygın yöntemlerden biri mekansal regresyon analizidir. Bu çalışmanın amacı mekansal analiz literatüründeki son gelişmeler ışığında mekansal etkilerin de dahil edildiği farklı mekansal modeller kullanarak Türkiye’de il düzeyindeki mutluluk verilerinde mekansal bağımlılık yapısının olup olmadığı incelemektir. Konum bilgisini içeren veriler mekansal bağımlılık kavramını ön plana çıkarmakta, mekansal verideki bağımlılık yapısı regresyon analizini de içeren çeşitli istatistiksel yöntemlerde geçerli olan bağımsızlık varsayımının ihlal edilmesine neden olmaktadır. Çalışmada Türkiye İstatistik Kurumu (TÜİK) tarafından il düzeyinde yapılan Yaşam Memnuniyeti Araştırması verileri kullanılarak sadece değişkenlerin almış oldukları değerler değil aynı zamanda konum bilgileri de hesaplamalara dahil edilerek mekansal etkilerin de eklendiği mekansal regresyon modelleri tahmin edilmiş, mekansal etkilerin modele dahil edildiği ve edilmediği regresyon analizi sonuçları karşılaştırılmıştır. Yapılan analizler sonucunda mekansal etkinin var olduğu, tahmin edilen mekansal regresyon analizi yardımıyla intihar ve çevre harcamaları değişkenlerinin dolaysız; işsizlik, gelir ve intihar değişkenlerinin ise dolaylı etkiye sahip olduğu sonucuna ulaşılmıştır.Spatial data analysis, whose results depend on the location of the event or the object being analyzed, consists of methods that require the use of both objects features and location. Especially developments in take place at GIS and programmes analyzing data enabled methods used in the analysis of spatial data more feasible. Spatial effect exits to forefront in spatial data analysis and it contains both spatial dependence and spatial heterogeneity. Spatial dependence or spatial autocorrelation reflects the situation in which the values observed in a place or region depend on the values of neighbor observations. Studies working spatial dependence should use methods taking this dependence into consideration. One of the most common method used in spatial analysis is spatial regression analysis. The aim of this study is to examine whether there is a spatial dependency structure in the happiness data at the provincial level in Turkey by using different spatial models including spatial effects in the light of the latest developments in the spatial analysis literature. Spatial dependence violates independence assumption valid for statistical methods. The results of the regression analysis, in which spatial effects are included in the model or not, were compared by using the data from the Life Satisfaction Survey conducted at the provincial level by the Turkish Statistical Institute (TUIK). As a result of the analyzes, it was determined that there is a spatial effect, and with the help of the estimated spatial regression analysis it has been concluded that the variables of suicide and environmental expenditures were directly; unemployment, income and suicide variables have indirect effect

Comparison of Invasive and Non-Invasive Liver Fibrosis Indicators in Chronic Hepatitis C Patients

Introduction: Liver biopsy is a standard method used to determine the stage of liver fibrosis. Base formulations have been developed to replace liver biopsy. Materials and Methods: All patients aged 18 years and older, who were diagnosed with chronic hepatitis C and underwent liver biopsy, and who presented to the outpatient clinic of infectious diseases and clinical microbiology at our hospital between January 2011 and January 2017, were included in the study. Liver biopsies of the patients were evaluated according to the modified Knodell (Ishak) fibrosis score. The patients were categorized into two groups based on their fibrosis scores: the low fibrosis group (F0, F1, F2) and the high fibrosis group (F3, F4, F5, F6). The diagnostic performance of non-invasive methods [modified fibrosis-4 index (mFIB-4), fibrosis-4 index (FIB-4), AST/platelet ratio (APRI), AST/ALT ratio (AAR), University of Gothenburg cirrhosis index (GUCI), King’s score, FibroQ test and Lok index] in predicting these two groups were compared retrospectively. Results: A total of 70 patients with chronic hepatitis C, comprising 40 women (57.1%) and 30 men (42.9%), who underwent liver biopsy and sought treatment at the outpatient clinic of infectious diseases and clinical microbiology between January 2011 and January 2017, were included in our study. The mean age of the patients was 50.47 ± 17 years. Based on liver biopsy results, there were 14 patients (20%) with a fibrosis score of 1, 25 patients (35.7%) with a score of 2, 20 patients (28.6%) with a score of 3, seven patients (10%) with a score of 4, and four patients (5.7%) with a score of 5. According to the Ishak score, there were 39 patients (55.7%) with low fibrosis and 31 patients (44.3%) with high fibrosis. The Area under the ROC Curve (AUROC), cut-off values, and p-values were compared to differentiate between patients with low fibrosis and those with high fibrosis. The highest AUROC value was found in the FIB-4 score, followed by the King’s score. Analyzing the noninvasive tests yielded the following results: FIB-4 index: AUROC= 0.749 (95% CI= 0.636-0.863, cutoff= 1.1276, sensitivity= 71%, specificity= 69.2%, p= 0.000); King’s score: AUROC= 0.733 (95% CI= 0.617-0.849, cut-off= 7.9069, sensitivity= 64.5%, specificity= 64.1%, p= 0.001); FibroQ index: AUROC= 0.668 (95% CI= 0.543-0.794, cut-off= 1.5981, sensitivity= 58.1%, specificity= 59%, p= 0.016); mFIB-4 index: AUROC= 0.647 (95% CI= 0.519-0.775, cut-off= 1.7118, sensitivity= 58.1%, specificity= 59%, p= 0.036); GUCI index: AUROC= 0.651 (95% CI= 0.522-0.780, cut-off= 0.4173, sensitivity= 61.3%, specificity= 61.5%, p= 0.031); APRI index: AUROC= 0.644 (95% CI= 0.515-0.774, cut-off= 0.4135, sensitivity= 61.3%, specificity= 59%, p= 0.039). Conclusion: In our study, we found that FIB-4 and King›s score can be used more safely than others in differentiating between low and high fibrosis
