Abstract
INTRODUCTION Diffuse large B-cell lymphoma (DLBCL) is the most common subtype of non-Hodgkin lymphomas. The aim of this study is to determine the relationship between the increase in the degree of fibrosis in the bone marrow and prognosis and mortality in newly diagnosed DLBCL. METHODS Bone marrow biopsy of 153 newly diagnosed DLBCL patients was determined by staining with reticulin, Masson's trichrome histochemical stain, and the degree of fibrosis was determined. RESULTS In the bone marrow biopsy performed at the time of diagnosis, bone marrow fibrosis (BMF) was observed in 70 patients. While BMF-1 was detected in 42 patients (60%), BMF-2 was detected in 25 patients (35%) and BMF-3 was detected in 3 patients (4%). As the degree of BMF increased, the median overall survival and median progression-free survival times were significantly shorter (p: 0.008), (p < 0.001). In patients with an increased degree of BMF, a significant decrease in leukocyte and neutrophil counts was observed after chemotherapy (p: 0.004). According to the results of the multivariate Cox regression model, it was determined that high NCCN-IPI risk (HR: 8.25; %95 CI: 1.09-62.52; p = 0.041) and being BMF ≥ 2 (HR: 3.75; %95 CI: 1.65-8.51; p = 0.002), increased the risk of death (p = 0.002, -2 loglikelihood = 392,553). CONCLUSION When the literature was reviewed, it was seen that this study was the first to define that bone marrow fibrosis grade 2 and above in DLBCL is a prognostic marker associated with worse survival. In the bone marrow pathology, which is examined to detect advanced disease in DLBCL, besides lymphomatous involvement, the detection of fibrosis grade is very important.

Abstract
INTRODUCTION In multiple myeloma cases, a variety of prognostic parameters have been identified, which contain the Durie-Salmon classification and the international staging system (ISS) that takes the serum ß2 microglobulin and albumin levels, platelet-to-lymphocyte ratio (PLR), neutrophil-to-lymphocyte ratio (NLR), and monocyte-to-lymphocyte ratio (MLR). This study investigates the effect of haemoglobin, albumin, lymphocyte and platelet (HALP) score which is a marker of inflammation status and nutrition, at the time of diagnosis for the patients with multiple myeloma on prognosis. METHODS A total of 200 multiple myeloma patients with HALP scores calculated from serum haemoglobin, albumin, lymphocyte count and platelet levels at the time of diagnosis were retrospectively examined. The effect of HALP score on overall survival (OS) and progression-free survival and its relationship between the previously evaluated prognostic parameters were investigated. RESULTS The optimal cut-off value with the ROC curves for the HALP score was 28.8. The patients were divided into two groups according to the optimal value of the HALP score (low-score group: HALP ≤28.8 [n: 134] and high-score group HALP >28.8 [n: 66]). In the group with the high HALP score, the OS was statistically longer than the low HALP score group (84 months and 53 months; p = 0.0001). In addition, when the effects of NLR, PLR, HALP score and ISS stage on OS were examined by multivariate analysis, all these markers were found to be statistically significant predictors. CONCLUSIONS HALP score may be a valuable prognostic marker for patients with multiple myeloma.

Abstract
PURPOSE Febrile neutropenia (FN) is a hematological emergency. It is challenging and confusing for the clinicians to make the decision of the febrile neutropenic patients under chemotherapy to be monitored at intensive care unit (ICU). The aim of this study was to define the factors supporting decision-making for the critical patients with febrile neutropenia. METHODS The data of 60 patients, who were taken to the ICU while they were under treatment in the Hematology Clinic with a diagnosis of febrile neutropenia, were analyzed retrospectively, in order to identify clinically useful prognostic parameters. RESULTS The ICU mortality rate was 80%. Mortality was significantly associated with higher sequential organ failure assessment score (SOFA), quick sequential organ failure assessment score (qSOFA), and hematological SOFA (SOFAhem) scores on admission. All cases having SOFA score 10 and above and qSOFA score 2 and above died. In multivariate analysis, qSOFA score was found to be statistically significant in predicting mortality in regard to ICU admission (p = 0.004). CONCLUSION Mortality of febrile neutropenic patients admitted to ICU is high. It would be appropriate to determine the extent of organ dysfunction instead of underlying disease, for making the decision of ICU admission. It should be noticed that the risk mortality is high for the FN cases with SOFA score 10 or above, qSOFA score 2 or above, and in need of mechanical ventilation and positive inotropic support; hence, early intervention is recommended. In our study, the most significant parameter in predicting ICU mortality was found to be qSOFA.

Abstract
BACKGROUND Recent reports showed neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and monocyte-to-lymphocyte ratio (MLR), as a predictor of progression-free survival (PFS) and overall survival (OS) in various malignancies. MATERIALS AND METHODS We retrospectively examined the PLR, NLR, and MLR in a cohort of 186 newly diagnosed multiple myeloma (MM) patients. This study investigated the prognostic relevance of NLR, PLR, and MLR in MM patients. NLR, PLR, and MLR were calculated from whole blood counts before therapy. The Kaplan-Meier curves and multivariate Cox models were used for the evaluation of survival. RESULTS Applying cutoff of 1.9 (NLR), 120.00 (PLR), and 0.27 (MLR), decreased PLR showed a negative impact on the outcome. Decreased PLR is an independent predictor for PFS and OS. There were no significant differences in median survival between the high and low NLR (P = 0.80) and MLR (P = 0.87) groups. CONCLUSIONS In this study, thrombocytopenia and low PLR are associated with poor survival in MM patients does this P value apply to thrombocytopenia or low PLR and may serve as the cost-effective prognostic biomarker.

Abstract
Peripheral blood is the prefered source for hematopoietic stem cells for hematopoietic stem cell transplantation. The efficiency of peripheral blood stem cell (PBSC) collection can vary among devices. In this study we aimed to compare feasibility and effectivity of apheresis procedures of the different systems. Two apheresis systems [Com.Tec (Fresenius Healthcare) and Spectra Optia (Caridian BCT)] were used in our center for the collection of PBSCs for autologous and allogeneic transplantation. We retrospectively analysed 190 apheresis procedures performed in healthy donors and patients between June 2012 and November 2014 in Department of Hematology, Dokuz Eylul University. PBSCS were collected by Fresenius cell separator (64 procedure) or Spectra Optia cell separator (126 procedure). Mobilization treatments were G-CSF (26.8%), cyclophosphamide plus G-CSF (48.4%), prelixafor plus G-CSF (14.7%), ESHAP (10%) and others. Patient and donor characteristics (age, weight, volume processed, disease, mobilization regimes) were similar in Fresenius and Spectra Optia apheresis groups. Altough both collected PBSCs efficiently, the amount of CD34+ cell in product collected by Spectra Optia device was significantly higher (p < 0.05) and product volume was lower than Fresenius Com.Tec significantly (p < 0.05). "CD34+ collection efficiency" with Spectra Optia was significantly higher than Fresenius Com.Tec (CE2: 87%, 70%, p = 0.033) regarding all procedures. High collection efficiency and low product volume may be a significant characteristic of Spectra Optia device (mean 187 mL, product CD34+ cell: 1576 µL).

Abstract
Plasma TAFI may participate in arterial thrombosis in cardiovascular diseases (CVD) and may be involved in the mechanism of vascular endothelial damage in diabetic patients. The aim of this study was to investigate the association of plasma TAFI antigen level in the development of diabetic foot ulcer in Type 2 diabetes. The TAFI antigen levels were determined in 50 patients with diabetic foot ulcers and 34 patients without diabetic foot ulcers and 25 healthy individuals. We measured TAFIa/ai antigen in plasma samples with a commercially available ELISA Kit. Diabetic foot ulcer group and diabetic group were similar in terms of mean age and sex distribution. Diabetes duration, retinopathy, neuropathy, macrovascular disease and infection were related to diabetic foot ulcers. HbA1c, HDL-cholesterol and Folic Acid levels were decreased in the diabetic foot ulcer group. TAFI levels were 99.44 ± 55.94% in control group, 135.21 ± 61.05% in diabetic foot ulcer group, 136.75 ± 59.38% in diabetic group and was statistically different (P < 0.05). But no difference was seen in TAFI levels between the diabetic foot ulcer group and diabetic group (P > 0.05). No significant difference in plasma TAFI levels were seen between diabetic foot ulcer stages. TAFI antigen levels are increased in Type 2 diabetic patients, but are not related to diabetic foot ulcer development.

Abstract
Introduction Oncocytic neoplasms occur in several organs and are most commonly found in the thyroid, kidneys and salivary glands. Oncocytic neoplasms of the adrenal cortex are extremely rare and are usually non-functioning. Case presentation We report the case of an adrenocortical oncocytic neoplasm with uncertain malignant potential in a 31-year-old man with Cushing's syndrome. The patient had been operated on following diagnosis of a 7 cm adrenal mass. Following surgery, the Cushing's syndrome resolved. The patient is still alive with no metastases one year after the surgery. Conclusion Adrenocortical oncocytic neoplasms must be considered in the differential diagnosis of both functioning and non-functioning adrenal masses.

Abstract
Ultrastructure of the membrana propria and the seminiferous epithelium was studied in infertile human testis both before and 3-6 months after varicocelectomy. The frequent alterations, observed before and after the operation, were extremely thickened membrana propria, deep invaginations, multilamination and knob-like formation of basal laminae and formation of multinucleated spermatids, which were all considered as the common response of the testis to different noxious agents. Although the cells of the seminiferous epithelium were clearly affected by varicocele before varicocelectomy, many areas exhibited normal features after the operation. Furthermore, multinucleated cells, sharing common features of Sertoli cell and spermatogonium, were observed, as well as presence of well-developed annulate lamellae in the Sertoli cells, exhibiting centrioles in the vicinity of their nuclei after varicocelectomy. These multiple ultrastructural observations indicate that Sertoli cell division takes place. This study suggests that if the observation period of the tissue samples after varicocelectomy is long enough, the reversible changes of the tubular cells would be seen much more frequently.

Abstract
In this study, eighteen Wistar female albino rats were used to observe the ultrastructural effects of toluene on the rat ovaries. The animals were divided into experimental and control groups. The experimental group was exposed to 3,000 ppm toluene/m3 for 7 days and 8 h/day. At the end of the experiment the main ultrastructural findings related to the oocytes of the antral follicles of the experimental group were: abundant vacuoles, lytic areas, degenerative mitochondria in the ooplasm and blunt microvilli on the surface. Furthermore, the granulosa cells revealed prominent degenerative changes such as pyknotic nuclei, mitochondrial alterations and dilatation of the endoplasmic reticulum (ER) cisternae. It was interesting to note tht the ultrastructure of primordial follicles was almost similar in both experimental and control groups. All these findings suggested that, although toluene did not affect the primordial follicles, the growing follicles showed degenerative changes attributable to the inhalation of a toxic agent such as toluene.
