Newly defined biomarker for the no reflow phenomenon in patients with non-ST elevation acute coronary syndrome; uric acid to creatinine ratio.

Background: The present study aimed to investigate whether newly defined serum uric acid (SUA) to serum creatinine ratio (SUA/SCr) predicts no-reflow phenomenon (NRP) development in patients with non-ST-elevated acute coronary syndrome (NSTE-ACS).

Methods: The study group was divided into two groups: those who developed NRP and those who did not. Complete blood counts, SUA, serum creatinine, C-reactive protein (CRP) and albumin were obtained at admission.

Association Between Baseline and Changes in Early Neutrophil-to-Lymphocyte Ratio on Survival in Patients with Metastatic Bladder Carcinoma Treated with Immunotherapy.

: A high baseline neutrophil-to-lymphocyte ratio (NLR) is a poor prognostic factor in various cancers. However, its predictive role in metastatic bladder cancer (mBC) treated with immunotherapy is unclear. In this study, we aimed to investigate the relationship between the baseline and change in NLR and overall survival in mBC patients treated with immunotherapy, with the potential to significantly impact patient care.

Evaluation of current patient-based real-time quality control in clinical chemistry testing.

Introduction: To perform simulation studies on patient-based real-time quality control (PBRTQC) for aspartate aminotransferase (AST), iron (Fe), potassium (K), and thyrotropin (thyroid stimulating hormone, TSH) analytes, focusing on optimizing systematic error detection while minimizing data loss.

Methods: Clinical laboratory data for the four analytes were analyzed using various truncation methods. Among these methods, truncation limits corresponding to fixed percentiles (e.

Rare Inherited Coagulation Deficiencies: A Single-Center Study.

Background: Rare factor deficiency (RFD) is characterized by a deficiency of factor (F)I, FII, FV, FVII, FX, FXI, FXII, FXIII, or a combined deficiency of FV+FVIII or vitamin K-dependent factors. The prevalence of RFD ranges from 1/1,000,000 to 3,000,000. Combined deficiencies of vitamin K-related factors have been described in 30 families worldwide, and these patients can present with a wide range of clinical symptoms, from mucocutaneous bleeding to life-threatening symptoms such as central nervous system and gastrointestinal bleeding.

Milk ladder: Who? When? How? Where? with the lowest risk of reaction.

The milk ladder (ML) approach, which is the gradual reintroduction of the milk allergen from the least allergenic forms to the most allergenic forms into the diet of the patients, has been utilized mostly in non-IgE-mediated but in some countries also in IgE-mediated-CMPA due to its possible benefits which include nutrition, quality of life and tolerance induction. Despite increasing interest, so far, there is no guideline on ML; thus, the use of this approach shows discrepancies among healthcare professionals as many factors such as dietary habits, patient history, test results, workload, and facilities of the hospitals, the anxiety of the parents/patients may affect the decision on how, when, where and whom to use ML. Here, we reviewed current data on implementing the ML, suggested a 4-step ML including receipts and amounts, and shared our experience on optimal patient selection, appropriate time and steps for initiating ML, and time intervals between the steps targeting the lowest risk of reaction.

Treatment Patterns and Attrition in Metastatic Renal Cell Carcinoma: Real-Life Experience from the Turkish Oncology Group Kidney Cancer Consortium (TKCC) Database.

Introduction: Despite the rapid evolution in management of metastatic renal cell carcinoma (mRCC) over the past decade, challenges remain in accessing new therapies in some parts of the world. Despite therapeutic advancements, attrition rates remain persistently high. This study aims to assess the treatment patterns and attrition rates of patients with mRCC in oncology clinics across Turkey.

Efficacy of Ruxolitinib in the management of chronic GVHD.

Objectives: Allogeneic hematopoietic stem cell transplantation (allo-HSCT) is a potentially curative treatment for hematological diseases, with success rates improving due to advancements in conditioning regimens and new anti-graft versus host disease (GVHD) drugs. Ruxolitinib, an oral selective Janus kinase (JAK) 1 and 2 inhibitor has been used to mitigate the effects of various inflammatory and myeloproliferative syndromes, given the JAK kinase pathway's central role in cytokine signaling during inflammatory and immune processes. In this study we aimed to assess ruxolitinib's efficacy in patients with chronic GVHD (cGVHD).

Cancer awareness across borders: a comparative study of internet search trends for breast and prostate cancer in Europe and Turkey.

Objectives: The governments and private organizations strongly support cancer awareness campaigns. It remains unknown whether the campaigns during the awareness months have the same effect in every country. This study aims to compare the impact of awareness campaigns conducted in October for breast cancer and September for prostate cancer on internet search trends among the most populous European countries and Turkey.

First case report of septic arthritis associated with an indwelling device.

Value of ACEF-II Score in Predicting Major Adverse Cardiac Events in Patients With Non-ST-Segment Elevation Myocardial Infarction and Unstable Angina.

Background: A score based on age, creatinine level, and ejection fraction as well as hematocrit value and the presence of emergency surgery (ACEF-II) has been proposed to have predictive value for risk stratification in cardiac surgery. This study aimed to evaluate its utility in patients with non-ST-segment elevation myocardial infarction and unstable angina (NSTEMI-ACS) to predict 1-year major adverse cardiac events (MACE).

Methods: In all, 768 patients with NSTEMI-ACS were enrolled in the study.

Lateralization outcomes of bilateral inferior petrosal sinus sampling: desmopressin vs CRH.

Purpose: Bilateral inferior petrosal sinus sampling (BIPSS) is the gold standard for localizing ACTH-dependent Cushing's syndrome (CS). While corticotropin-releasing hormone (CRH) was initially used for stimulation, desmopressin has become a common alternative. This research evaluates desmopressin's effectiveness in lateralizing Cushing's disease (CD) during BIPSS compared to CRH stimulation.

Abscopal effect-induced spontaneous regression of distant metastases in malignant mesenchymal tumor: a case report.

The abscopal effect refers to an anti-tumor response that occurs in areas where radiotherapy (RT) has not been directly administered but is triggered by the immune system. We presented a case of an undifferentiated pleomorphic sarcoma with three relapses that showed a complete response after distant metastatic disease. The tumor was initially detected in the left pectoral muscle.
