Decreased Aortic Elasticity in Rheumatoid Arthritis: An Early Sign of Atherosclerosis and Predictive Factors.

Background: Atherosclerosis is increased in patients with rheumatoid arthritis (RA) and early diagnosis of vascular disease leads to better outcome. Our aim was to evaluate whether aortic elasticity decreases in the subclinical stage of atherosclerosis in RA patients without any cardiovascular disease and to determine disease-related risk factors.

Methods: One hundred fourteen patients with RA, 50 patients with spondyloarthritis, and 50 healthy control were included in this study.

Is 3D Volumetric Evaluation Consistent with Postoperative Renal Parenchymal Preservation in Open and Robot-Assisted Laparoscopic Partial Nephrectomy?

To evaluate by using 3D renal volumetric assessment and compare renal parenchymal preservation between patient who underwent open partial nephrectomy (OPN) and robot assisted laparoscopic partial nephrectomy (RALPN). We retrospectively reviewed the records of the patients to evaluate the effect of OPN (23 patients) or RALPN (19 patients) partial nephrectomy on renal parenchymal preservation. The CT or MRI were examined using 3D-Slicer image processing software.

Evaluation of cardiac autonomic dysfunctions in children with type 1 diabetes mellitus.

Background: Cardiovascular autonomic neuropathy (CAN) is a serious complication of diabetes, impacting the autonomic nerves that regulate the heart and blood vessels. Timely recognition and treatment of CAN are crucial in averting the onset of cardiovascular complications. Both clinically apparent autonomic neuropathy and subclinical autonomic neuropathy, particularly CAN pose a significant risk of morbidity and mortality in children with type 1 diabetes mellitus (T1DM).

The association of HLA-DRB1 alleles and MBL2 gene variant in pediatric acute lymphoblastic leukemia patients.

Introduction: Epidemiologic studies on pediatric acute lymphoblastic leukemias (ALL) have been conducted to evaluate the possible risk factors including genetic, infectious and environmental factors with the objective of idenfying the etiology. Mannose-binding lectin 2 (MBL2) plays an important role in first-line immune defense. HLA DRB1 alleles play a role in presentation of peptides to T cells and in activation of the adaptive immune response.

27 years of experience with the Fontan procedure: characteristics and clinical outcomes of children in a tertiary referral hospital.

Background: The Fontan operation has improved the survival of children born with congenital heart disease with single ventricle physiology. The most widely adopted variations of the Fontan procedure are the extracardiac conduit, the lateral tunnel ve the intra/extracardiac conduit with fenestration. Despite advances in the treatment and prevention of early and late complications that may develop after Fontan surgery, morbidity still remains an important problem.

Left ventricular non-compaction cardiomyopathy: restrictive subtype with MYH7 gene mutation.

Left ventricular non-compaction is a very rare, still unclassified congenital cardiomyopathy. Nine distinct subtypes of functional and anatomical left ventricular non-compaction have been identified. Studies on the prognosis and mortality of subtypes are ongoing.

Evaluation of ganglion cell complex and retinal nerve fiber layer in children with spina bifida using optical coherence tomography.

Purpose: Spina bifida (SB) is a congenital disorder caused by the incomplete fusion of the embryonic neural tube during spinal cord development. In this study, we used Spectral Domain Optic Coherence Tomography (SD-OCT) for retinal nerve fibre layer (RNFL) and ganglion cell complex (GCC) analyses and compared the results of healthy children and SB patients in a similar age group.

Methods: Our study was planned prospectively and conducted between June 2017 and July 2019.

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.

T2-weighted magnetic resonance imaging as a novel predictor of surgical remission in newly diagnosed pituitary macroadenomas presenting as acromegaly.

Background: Any preoperative diagnostic assessment that can predict the success of the operation in acromegaly will provide a positive impact on overall remission rates. The aim of this study is to reveal whether the signal intensity in T2-weighted Magnetic Resonance Imaging can predict postoperative results in acromegaly patients with macroadenoma.

Methods: We analyzed our surgical results in regard to T2-weighted images in newly diagnosed consecutive 124 patients with acromegaly, operated between 2014 and 2019.

Fibroblast Growth Factor Receptor-4 Expression in Pituitary Adenomas is Associated with Aggressive Tumor Features.

Purpose: To investigate the relationship of Fibroblast Growth Factor Receptor-4 (FGFR-4) expression with radiologic, pathologic, and clinical parameters in pituitary adenomas.

Methods: Among 307 patients who underwent pituitary surgery for a pituitary adenoma between 2000 and 2015, we included 161 patients (53 gonadotroph, 26 corticotroph, 25 null cell, 22 lactotroph, 13 somatotroph, 8 adenomas with unusual combination, 7 Pit-1 positive adenomas, and 7 lactosomatotroph) based on availability of pathology specimens. Patients' radiologic, pathologic, and clinical parameters were determined.

Real Life Data of Treat and Extend Intravitreal Ranibizumab and Aflibercept Therapy in Wet Age-related Macular Degeneration Patients: 3-Year Results.

Purpose: To compare functional and anatomic outcome of intravitreal ranibizumab (IVR) and intravitreal aflibercept (IVA) treatments in neovascular age-related macular degeneration by using the treat and extend (TE) protocol.

Methods: In this retrospective chart study, treatment naïve 74 eyes of 74 age-related macular degeneration patients treated with IVR and IVA (38 eyes in IVR and 36 eyes in IVA group) with TE protocol were included. Following three consecutive monthly intravitreal injections, TE protocol was applied to each group.

SNPs of miR-23b, miR-107 and HMGA2 and their Relations with the Response to Medical Treatment in Acromegaly Patients.

Introduction: Acromegaly is a chronic disease of increased growth hormone (GH) secretion and elevated insulin-like growth factor-I (IGF-I) levels induced by a pituitary adenoma. HMGA2 (high mobility group A2) and AIP (aryl hydrocarbon receptor-interacting protein) expression levels are related to GH-secreting adenomas, and also a response to Somatostatin Analogs (SSAs). We studied SNPs in miR-107 and miR-23b that related with AIP and HMGA2 genes respectively and control their expression, and also SNP in the 3'UTR of HMGA2 gene.

The Feasibility of Conventional Forward-viewing Endoscope for Endoscopic Retrograde Cholangiopancreatography in Patients With Altered Gastrointestinal Anatomy.

Background: Endoscopic retrograde cholangiopancreatography (ERCP) has been commonly used for biliopancreatic diseases of patients with normal gastrointestinal (GI) anatomy with a success rate of >90%. However, this procedure may also be necessary in patients with altered GI anatomy such as Billroth II or Roux-en-Y reconstructions. Performing ERCP in these patients may pose extreme technical challenges, and increase the risk of complications.
