Toxoplasmic encephalitis after allogeneic hematopoietic stem cell transplantation

Cerebral toxoplasmosis is a rare but often life-threatening infection after hematopoietic stem cell transplantation (HSCT). In such cases, early diagnosis and initiation of treatment are vital. We describe a case of cerebral toxoplasmosis in a patient who underwent HSCT for acute myeloid leukemia. Infection was diagnosed with polymerase chain reaction (PCR) test of cerebrospinal fluid and cranial magnetic resonance imaging scan. The patient treated with trimethoprim-sulfamethoxazole and clindamycin combination. However, she died from nosocomial infection after 15 days of treatment. This life-threatening infection should be considered in a patient who is post-HSCT present with neurologic symptoms and brain lesions. PCR is an important and rapid diagnostic tool for toxoplasmosis. Cranial imaging scan and PCR should be used together to diagnosed

Could plasma asymmetric dimethylarginine level be a novel predictor beyond the classic predictors of stent restenosis?

Objective: The aim of this study was to investigate the factors associated with coronary stent restenosis and if there is an association between plasma asymmetric dimethylarginine (ADMA) levels and stent restenosis. Methods: Ninety-one patients, who had a history of coronary bare metal stent implantation due to any cause in the last one year period, were admitted to this observational cross-sectional study. Coronary angiography was performed to all patients and quantitative angiography was used to determine the presence of stent restenosis. Laboratory parameters and angiographic features that contribute to stent restenosis were evaluated. Plasma ADMA levels were measured by using high performance liquid chromatography. Logistic regression analysis was used to determine the independent factors of stent restenosis. Results: Angiographic restenosis was found in 35 patients (38.5%). Stent diameter (p=0.038) and left ventricular ejection fraction (p=0.023) were lower and stent implantation history due to acute coronary syndrome (p=0.029), plasma ADMA level (5.0 +/- 1.8x10(-4) mmol/L vs. 3.9 +/- 1.0x10(-4) mmol/L, p=0.001), C-reactive protein concentration (p=0.016), white blood cell count (p=0.044) and stent length (p=0.005) were higher in patients with restenosis. Plasma ADMA level (beta=0.536; OR: 1.710; CI: 1.022-2.861; p=0.041), C-reactive protein concentration (beta=0.062; OR: 1.064; CI: 1.003-1.129; p=0.041), stent diameter (beta=-3.047; OR: 0.048; CI: 0.007-0.313; p=0.002) and length (beta=0.165; OR: 1.179; CI: 1.036-1.343; p=0.013) were found to be the independent predictors of stent restenosis in logistic regression analysis. Conclusion: We conclude that plasma ADMA levels may be used as a novel marker for stent restenosis beyond the classic stent restenosis markers

Information, attitude, and behavior toward organ transplantation and donation among health workers in the Eastern Black Sea Region of Turkey

Aim: We sought to evaluate the information, attitude, and behaviors toward organ donation among health workers in the eastern Black Sea region of Turkey. Method: This descriptive study was performed between December 2008 and November 2009. It involved 1,545 health personnel in 8 state hospitals in the eastern Black Sea region of Turkey, excluding the university hospitals in the towns of Trabzon, Rize, Gmhane, and Giresun. Educational seminars regarding organ transplantation and donation were arranged for the hospitals in the study. Questionnaires on the subject distributed to the participants were collected before the seminars began. They contained questions about occupation, gender, age, previous organ donation, whether the person would consider donating if they had not already volunteered (if not, the reasons why), whether any relatives had volunteered to donate organs, whether anyone close to them had volunteered to donate organs, whether they would donate organs in the event of a relative's death, and what they might think if they were to require an organ transplant. Following the seminars, participants were given the opportunity to obtain organ donation cards from a stand on site. Data were analyzed using the chi-square test. Results: Eighty-one participants (5.2%), including 46 women (5.2%) and 35 men (5.3%), had previously officially volunteered to donate organs (P = .875). One hundred thirty-seven health personnel were willing to donate organs by visiting the donation stand after the seminars. The main reasons for participants who had not volunteered to donate organs failing to do so were lack of information about donation and procedures (28.4%), lack of interest in the subject (23.2%), and Islamic religious beliefs and/or traditions (19.6%). One hundred eighty health personnel (11.7%) had family members or relatives who had volunteered to donate organs. Asked whether they would donate that person's organs in the event of the death of a relative, 93 doctors (67.6%), 225 nonphysician health personnel (41.1%), and 345 other participants (43.1%) stated that they would not (P < .0005). Conclusions: Health workers play a key role to overcome the difficulties encountered regarding organ donation. This study showed the need for constant effective education seminars to enhance knowledge and sensitivity on the part of health workers. © 2011 Elsevier Inc. All rights reserved

The Effect of Mesenchymal Stromal Cells on the Mortality of Patients with Sepsis and Septic Shock: A Promising Therapy

Purpose. Sepsis and septic shock are the major causes of death in intensive care units. This study aimed to evaluate the clinical safety and efficacy of mesenchymal stem cells (MSCs) in sepsis and septic shock patients. Methods. Ten patients were enrolled in the study. Adipose-derived MSC infusions were given (1 x 10(6)/kg, on the 1st, 3rd, 5th, 7th, and 9th days of therapy) together with standard therapy. Before the MSC applications, blood samples were collected for cytokine assessment (TNF-alpha, IFN-gamma, IL-2, IL-4, IL-6, IL-10). The clinical and laboratory improvements were recorded and compared with control groups selected retrospectively. The clinical trial was registered on 16.03.2022 with the registration number . Results. In the study group, the ages of patients ranged from 22 to 68 years, and APACHE II scores ranged from 14 to 42. In the control group, ages ranged from 22 to 80 years and their APACHE II scores were between 14-35. The survival rate in the study group was 100% on the 14th day whereas it was 70% on the 28th day. A significant decrease in the SOFA score (adjusted), clinical, and laboratory improvements were observed during the MSC administration. However, no significant cytokine level changes were observed. In the control group, the survival rate of 20 patients was 70% on the 14th day, whereas 60% was on the 28th day. While deaths were observed in the control group in the first week of treatment, deaths in the MSCs group were observed between the 15th and 28th days. Conclusion. MSCs treatment may have a positive impact on the survival rates of sepsis during the early phase. However, further randomized controlled studies with a large group of patients are needed
