Abstract
AIM OF STUDY The NLR is a simple and inexpensive parameter that is useful as a marker of subclinical inflammation. The purpose of this study was to investigate the clinical characteristics of patients diagnosed with acute cerebral ischemia at the time of initial evaluation in the emergency department. PATIENTS AND METHODS The study was designed as a multicentre cross-sectional study of acute ischemic stroke patients. Neurological evaluations were assessed using the NIHSS and mRS. Evaluations included the results of patients' laboratory tests performed at the time of presentation to the emergency department. RESULTS Seven hundred and thirty-five ischemic stroke patients were included in the study. Stroke cases assessed by the mRS as mild or severe showed significant differences with respect to age, leukocyte counts, neutrophil counts, NLR, LDL cholesterol values, and serum glucose values (P = .001). When analysed using NIHSS, lymphocyte levels were significantly higher in very severe stroke cases compared with mild, moderate, and severe cases. NLR was also significantly higher in very severe stroke cases and severe stroke cases as compared with the mild and moderate stroke groups. Neurological evaluations assessed using the mRS showed a mild positive correlation with neutrophil and leukocyte count and a weak correlation with the NLR. CONCLUSION The NLR exhibited a significant correlation with the results of the mRS and NIHSS. The NLR measured in the very early period was also significantly associated with clinical condition. These results suggest that high NLR values may be a marker of stroke' severity.What's known Stroke is an important disease that has a significant impact on mortality and morbidity and is closely related to the aging world population. In recent years, highly innovative approaches have been developed in the treatment of stroke. Although a long distance has been covered in the early diagnosis of stroke, the ability to predict the severity of the disease with many parameters is still up to date. What's new At the time of admission, in the absence of infection, parameters such as leukocytelymphocyte count and NLR may be telling about stroke severity. Demonstrating the utility of these simple, practical, inexpensive and naninvasive parameters to predict stroke severity can contribute to the scoring to be established at the time of initial diagnosis.

Abstract
IMPORTANCE The presence of atrophy on magnetic resonance imaging can support the diagnosis of the behavioral variant of frontotemporal dementia (bvFTD), but reproducible measurements are lacking. OBJECTIVE To assess the diagnostic and prognostic utility of 6 visual atrophy scales (VAS) and the Magnetic Resonance Parkinsonism Index (MRPI). DESIGN, SETTING, AND PARTICIPANTS In this diagnostic/prognostic study, data from 235 patients with bvFTD and 225 age- and magnetic resonance imaging-matched control individuals from 3 centers were collected from December 1, 1998, to September 30, 2019. One hundred twenty-one participants with bvFTD had high confidence of frontotemporal lobar degeneration (FTLD) (bvFTD-HC), and 19 had low confidence of FTLD (bvFTD-LC). Blinded clinicians applied 6 previously validated VAS, and the MRPI was calculated with a fully automated approach. Cortical thickness and subcortical volumes were also measured for comparison. Data were analyzed from February 1 to June 30, 2020. MAIN OUTCOMES AND MEASURES The main outcomes of this study were bvFTD-HC or a neuropathological diagnosis of 4-repeat (4R) tauopathy and the clinical deterioration rate (assessed by longitudinal measurements of Clinical Dementia Rating Sum of Boxes). Measures of cerebral atrophy included VAS scores, the bvFTD atrophy score (sum of VAS scores in orbitofrontal, anterior cingulate, anterior temporal, medial temporal lobe, and frontal insula regions), the MRPI, and other computerized quantifications of cortical and subcortical volumes. The areas under the receiver operating characteristic curve (AUROC) were calculated for the differentiation of participants with bvFTD-HC and bvFTD-LC and controls. Linear mixed models were used to evaluate the ability of atrophy measures to estimate longitudinal clinical deterioration. RESULTS Of the 460 included participants, 296 (64.3%) were men, and the mean (SD) age was 62.6 (11.4) years. The accuracy of the bvFTD atrophy score for the differentiation of bvFTD-HC from controls (AUROC, 0.930; 95% CI, 0.903-0.957) and bvFTD-HC from bvFTD-LC (AUROC, 0.880; 95% CI, 0.787-0.972) was comparable to computerized measures (AUROC, 0.973 [95% CI, 0.954-0.993] and 0.898 [95% CI, 0.834-0.962], respectively). The MRPI was increased in patients with bvFTD and underlying 4R tauopathies compared with other FTLD subtypes (14.1 [2.0] vs 11.2 [2.6] points; P < .001). Higher bvFTD atrophy scores were associated with faster clinical deterioration in bvFTD (1.86-point change in Clinical Dementia Rating Sum of Boxes score per bvFTD atrophy score increase per year; 95% CI, 0.99-2.73; P < .001). CONCLUSIONS AND RELEVANCE Based on these study findings, in bvFTD, VAS increased the diagnostic certainty of underlying FTLD, and the MRPI showed potential for the detection of participants with underlying 4R tauopathies. These widely available measures of atrophy can also be useful to estimate longitudinal clinical deterioration.

Abstract
OBJECTIVES Multiple sclerosis is usually clinically characterized by repeated subacute relapses followed by remissions. Corticosteroids are used for relapses, and this treatment has been shown to increase the speed of recovery from these. We aimed to evaluate the efficacy and safety of pulsed methylprednisolone given every month as an add-on therapy to interferon beta or glatiramer acetate in patients with relapsing-remitting multiple sclerosis. PATIENTS AND METHODS This was a multi-center, examiner-blinded, prospective study. Absolute annualized relapse rates and Expanded Disability Status Scale scores were calculated. RESULTS 103 patients were given intravenous methylprednisolone (1 dose of 1g IV) once a month for 12 months as add-on therapy and were assessed during this period. The decrease in the absolute annualized relapse rate was 0.69, and 72 patients were relapse-free at the end of the year. Sixty-nine of the 103 patients had the same Expanded Disability Status Scale scores at the end of one year, while 21 were less disabled, and 13 sustained disability progression. Health related quality of life measured using the MS Quality of Life scale improved significantly during the study period. CONCLUSION The addition of monthly pulsed methylprednisolone to subcutaneous interferon beta or glatiramer acetate therapy significantly reduced the relapse rate and may also be beneficial in terms of disease progression. These combinations were also safe, and most patients tolerated methylprednisolone as an add-on to interferon beta or glatiramer acetate.

Abstract
INTRODUCTION Severe respiratory failure develops as a result of the involvement of the respiratory muscles in patients with amyotrophic lateral sclerosis (ALS). Implantation of diaphragm pacing system (DPS) has been carried out on ALS patients since 2005 to avoid these situations, but the importance of diaphragm thickness has not yet been established clearly. MATERIAL AND METHOD We retrospectively evaluated 34 ALS patients who had previously implanted DPS to detect the importance of diaphragm thickness. We investigated the effect of diaphragm thickness, which was measured by preoperative thorax computerized tomography on preoperative respiratory function tests (RFT), arterial blood gas (ABG) analysis, postoperative 3- and 6-month oxygen saturations and mortality. RESULTS The right diaphragm thickness was calculated as 4.60 (2.95-6.00) mm, while the left diaphragm thickness was 4.10 (2.77-6.00) mm. Six patients died during the follow-up period. We did not detect a significant relationship between ABG parameters, RFT and diaphragm thickness. However, according to our observations, the diaphragm thickness was significantly related to mortality. The right diaphragm was significantly thinner in cases that required preoperative respiratory support and had percutaneous endoscopic gastrostomy. When the cut-off values for the diaphragm thickness were accepted as 3.50 mm, significantly higher mortality among patients below this was observed. CONCLUSION Diaphragm thickness is an important criterion in cases for which DPS implantation is planned. We consider that avoidance of DPS implantation is more suitable for cases with a diaphragm thickness below 3.50 mm because of mortality.

Abstract
OBJECTIVE This study was planned to assess the vena contracta (VC), flow convergence area (PISA) and jet area (JA) methods in evaluating the severity of mitral regurgitation (MR) and to test the accuracy of a proposed algorithm using these methods. METHODS Eighty-seven patients with chronic MR were enrolled in the study. VC of < 0.3 cm, maximal MR flow rate calculated by PISA (Qmax) of < 72 cm3/sn and JA of < 4 cm2 were classified as mild MR. VC of > 0.5 cm, Qmax of > 240 cm3/sn and JA of > 8 cm2 were classified as severe MR. Whereas the values between these ranges were called to be moderate MR. The algorithm was planned as follows: In the first step, VC width was measured. If a patient has VC = 0.3-0.5 cm, it was used Qmax in the eccentric jets and JA in the central jets in the second step. The severity of MR were considered as severe, moderate and mild for > 50%, 21-49% and 20% of the regurgitant fraction calculated by the reference method (the quantitative Doppler method depending on aortic and mitral stroke volumes), respectively. RESULTS The sensitivity of VC was low in differentiating between moderate and severe MR (63%). In eccentric jets, the regurgitant volume calculated by PISA was higher than that of reference method (70 +/- 49 vs. 59 +/- 29 cm3) and the JA was found to be less than that of central jets despite similar regurgitant fraction (6.8 +/- 3.2 vs. 8.5 +/- 3.3 cm2). The algorithm agreed well with the reference method and it was better than those of each tree methods (Cappa coefficients 0.89 vs. 0.65, 0.63 and 0.45 for VC, Qmax and JA; respectively). The accuracies of the algorithm in discriminating between mild and moderate MR or severe and non-severe MR were high (98% and 95%, respectively). CONCLUSIONS The severity of MR can be determined accurately and simply by using VC, PISA and JA methods together.

Abstract
BACKGROUND/AIM Pyridoxine deficiency may be the cause of failure to respond appropriately to iron and erythropoietin (EPO) administration in hemodialysis patients. METHOD We studied 36 patients on chronic hemodialysis amply supplemented with iron and EPO, who failed to raise hematocrit levels >33%. Patients were divided into three equal groups and evaluated for 6 months as follows: Group A -- no additional therapy; group B -- supplemented with oral pyridoxine 50 mg/day, and group C received 100 mg/day pyridoxine orally. RESULTS In all our patients, erythrocyte pyridoxine levels were initially within reference range for a healthy population and did not vary significantly during the study period. Likewise, ferritin levels and iron saturation values remained normal and constant. Hemoglobin and/or hematocrit levels remained practically unchanged in all three groups. CONCLUSIONS The results indicate that in hemodialysis patients with normal pyridoxine status who, despite appropriate supplementation of iron and EPO, fail to reach optimal hematocrit levels, additional pyridoxine treatment does not produce any hematocrit elevation.

Abstract
OBJECTIVE IL-8 is thought to be the principal chemokine responsible for neutrophil activation and tissue infiltration in patients with Behçet's disease (BD). In various studies serum levels of IL-8 were reported to be increased. METHODS IL-8 mRNA was purified from both peripheral whole blood samples and separated lymphocytes, granulocytes and monocytes of patients with BD and compared to that from healthy (HC) and disease controls. IL-8 sequences were revealed by PCR amplification using appropriate sequence-specific primers. mRNA levels were determined semi-quantitatively using an image analyser in comparison with beta-actin. RESULTS Although the differences did not reach statistical significance, BD patients tended to have higher IL-8 mRNA levels compared to HC in whole blood samples (2.0 +/- 1.4 vs 1.5 +/- 1.2) as well as in their lymphocytes (2.7 +/- 1.6 vs 1.5 +/- 0.9). No differences were observed between BD and HC in monocyte or granulocyte IL-8 mRNA levels. CONCLUSION Our results suggest that the cellular source of IL-8 is diverse in BD with a possible major contribution by lymphocytes.

Abstract
In order to investigate the relationship between aberrant marker expression and DNA ploidy, 61 adult patients with acute leukemia (39 AML and 22 ALL) were studied. Aberrant marker expression was observed in 20 patients (16/39 of AML and 4/22 of ALL patients). In flow cytometric DNA analysis aneuploidy was observed in 18 patients (9/39 of AML and 9/22 of ALL patients). The incidence of aneuploidy in patients with aberrant marker expression was 35% whereas this was 26.8% in patients without aberrant marker expression. Furthermore, 7 patients with aberrant marker expression showed an aneuploid, double G0/G1 peaks appearance whereas the remaining 11 patients with aberrant marker expression had euploid DNA content. Double G0/G1 appearance was not observed in patients without aberrant marker expression. Further analyses revealed that this did not correlate with apoptosis. All 7 patients, who had both aberrant marker expression and double G0/G1 peak had a poor clinical outcome with a short survival and all died within three months whereas three-months survival was 67% for AML, 69% for ALL patients and 81% for patients with aberrant marker expression respectively (p<0.01). Our data indicate that the evaluation of the DNA ploidy in patients with aberrant marker expression may be of prognostic importance.
