Nafile Soydaşlık: Irak ve Bulgaristan Türkleri örneğinde göçmen, dernek ve devlet

Bu makalede, Bulgaristan ve Irak’tan gelen Türk göçmenler örneğinde hem tarihsel, hem de gruplar arası bir karşılaştırma yaparak Türkiye’de bulunan ve Türk soylu diye nitelendirilen yabancıların iskân ve adaptasyonunda “Türk soylu” olmanın değişen anlamlarını ve bu süreçte devletin rolünü inceleyeceğiz . “Türk kökenli,” ya da bazı hukuki metinlerde yer aldığı şekliyle “Türk soylu” olma ibaresinin aşikar bir kategoriymişçesine kullanılmasını sorunsallaştırırken, üç kademeli bir argüman önermekteyiz: 1) devlet, Türk kökenli addedilen göçmenlere yönelik tutumunda göçmenlerin geldiği coğrafyaya göre değişen bir ayrışma, veya bizim tabirimizle, bir “makbullük hiyerarşisi” gözetmekle beraber; 2) bu hiyerarşi tarih boyunca sabit olmayıp, hiyerarşinin en tepesindekiler dahil, aslında herkesin “Türklüğü” zaman zaman zan altında kalmış; ve 3) doksanlardan itibaren Türk devletinin benimsediği yeni politikalarla, “Türk kökenli” addedilen göçmenlerin görece ayrıcalıklı konumları iyice zayıflamıştır

An evaluation of six-year Stenotrophomonas maltophilia infections in a university hospital

Background: Stenotrophomonas maltophilia is a Gram-negative bacillus and opportunistic emergent pathogen causing hospital-acquired infections (HAIs). Due to risk factors such as prolonged intensive care unit stay and invasive procedures, it has become one of the leading causes of HAIs. Objective: The aim of this study was to evaluate the epidemiology of S.maltophilia infections over a six-year period at D & uuml;zce University Hospital, Turkey. Methods: The incidence, clinical characteristics, antimicrobial susceptibility and outcomes of nosocomial S. maltophilia in-fections during this period were retrospectively analyzed. Results: During the study period, 67 samples obtained from 61 patients were identified. Pneumonias (82%) were the most common HAIs, followed by bloodstream infections (10.5%), urinary tract infections (3%), skin and soft tissue infections (3%) and surgical site infection (1.5%). Admission to intensive care, hospitalization exceeding 30 days, and previous use of broad-spectrum antibiotics constituted risk factors. Resistance to cotrimoxazole (6%) was lower than that to levofloxacin (18%). Conclusion: The most important risk factors for S.maltophilia infection in patients are previous exposure to antibiotics, prolonged hospitalization and invasive procedures such as mechanic ventilation. Discharging patients as early as possible with the rational use of antibiotics may be effective in reducing S. maltophilia infections and resistance rates.WOS:0006373648000122-s2.0-85092222085PubMed: 3340295

Changes in intracellular protein expression in cortex., thalamus and hippocampus in a genetic rat model of absence epilepsy

WOS: 000289958600003PubMed ID: 21310218Epilepsy is a chronic disorder characterized by repeated seizures resulting from abnormal activation of neurons in the brain. Although mutations in genes related to Na+, K+, Ca2+ channels have been defined, few studies show intracellular protein changes. We have used proteomics to investigate the expression of soluble proteins in a genetic rat model of absence epilepsy "Genetic Absence Epilepsy Rats from Strasbourg (GAERS)". The advantage of this technique is its high throughput quantitative and qualitative detection of all proteins with their post-translational modifications at a given time. The parietal cortex and thalamus, which are the regions responsible for the generation of absence seizures, and the hippocampus, which is not involved in this activity, were dissected from GAERS and from non-epileptic control rat brains. Proteins from each tissue sample were isolated and separated by two-dimensional gel electrophoresis. Spots that showed significantly different levels of expression between controls and GAERS were identified by nano LC-ESI-MS/MS. Identified proteins were: ATP synthase subunit delta and the 14-3-3 zeta isoform in parietal cortex; myelin basic protein and macrophage migration inhibitory factor in thalamus; and macrophage migration inhibitory factor and 0-beta 2 globulin in hippocampus. All protein expressions were up-regulated in GAERS except 0-beta globulin. These soluble proteins are related to energy generation, signal transduction, inflammatory processes and membrane conductance. These results indicate that not only membrane proteins but also cytoplasmic proteins may take place in the pathophysiology and can be therapeutic targets in absence epilepsy. (C) 2011 Elsevier Inc.

COVID-19 in Kidney Transplant Recipients: A Multicenter Experience from the First Two Waves of Pandemic

Background Kidney transplant recipients have an increased risk of complications from COVID-19. However, data on the risk of allograft damage or death in kidney transplant recipients recovering from COVID-19 is limited. In addition, the first and second waves of the pandemic occurred at different times all over the world. In Turkey, the Health Minister confirmed the first case in March 2020; after that, the first wave occurred between March and August 2020; afterward, the second wave began in September 2020. This study aims to demonstrate the clinical presentations of kidney transplant recipients in the first two waves of the pandemic in Turkey and explore the impact of COVID-19 on clinical outcomes after the initial episode. Methods Patients with COVID-19 from seven centers were included in this retrospective cohort study. Initially, four hundred and eighty-eight kidney transplant recipients diagnosed with COVID-19 between 1 March 2020 to 28 February 2021 were enrolled. The endpoints were the occurrence of all-cause mortality, acute kidney injury, cytokine storm, and acute respiratory distress syndrome. In addition, longer-term outcomes such as mortality, need for dialysis, and allograft function of the surviving patients was analyzed. Results Four hundred seventy-five patients were followed up for a median of 132 days after COVID-19. Forty-seven patients (9.9%) died after a median length of hospitalization of 15 days. Although the mortality rate (10.1% vs. 9.8%) and intensive care unit admission (14.5% vs. 14.5%) were similar in the first two waves, hospitalization (68.8% vs. 29.7%; p < 0.001), acute kidney injury (44.2% vs. 31.8%; p = 0.009), acute respiratory distress syndrome (18.8% vs. 16%; p = 0.456), and cytokine storm rate (15.9% vs. 10.1%; p = 0.072) were higher in first wave compared to the second wave. These 47 patients died within the first month of COVID-19. Six (1.4%) of the surviving patients lost allografts during treatment. There was no difference in the median serum creatinine clearance of the surviving patients at baseline (52 mL/min [IQR, 47-66]), first- (56 mL/min [IQR, 51-68]), third- (51 mL/min [IQR,48-67]) and sixth-months (52 mL/min [IQR, 48-81]). Development of cytokine storm and posttransplant diabetes mellitus were independent predictors for mortality. Conclusions Mortality remains a problem in COVID-19. All the deaths occur in the first month of COVID-19. Also, acute kidney injury is common in hospitalized patients, and some of the patients suffer from graft loss after the initial episode

The efficacy and tolerability of glecaprevir/pibrentasvir treatment in a real-world chronic hepatitis C patients cohort

Background and Aim: The aims of the present study were to evaluate the real-life efficacy and tolerability of glecaprevir (GLE)/pibrentasvir (PIB) in the treatment of patients with chronic hepatitis C (CHC). Materials and Methods: Between May 2019 and May 2022, 686 patients with CHC, treated with GLE/PIB combination from 21 participating centers in Turkiye, were enrolled in the study. Results: All patients were Caucasian, and their median age was 56 years. At the start of GLE/PIB treatment, the median serum Hepatitis C virus RNA and serum alanine amino transaminase (ALT) levels were 6.74 log10 IU/mL and 47 U/L, respectively. Fifty-three percent of the patients were infected with genotype 1b, followed by genotype 3 (17%). Diabetes was the more common concomitant disease. The sustained virological response (SVR12) was 91.4% with intent-to-treat analysis and 98.5% with per protocol analysis. The SVR12 rates were statistically significant differences between the patients who were i.v. drug users and non-user (88.0% vs. 98.8%, p=0.025). From the baseline to SVR12, the serum ALT levels and Model for End-Stage Liver Disease score were significantly improved (p<0.001 and p=0.014, respectively). No severe adverse effect was observed. Conclusion: GLE/PIB is an effective and tolerable treatment in patients with CHC
