Background: This study investigates the role of Delta Neutrophil Index (DNI), an inflammation marker, in late-onset fetal growth restriction (LO-FGR) and its prediction of composite adverse neonatal outcomes.

Methods: A retrospective study was conducted on 684 pregnant women (456 with normal fetal development and 228 with LO-FGR) who delivered at Health Sciences University Etlik Zubeyde Hanim Women's Health Training and Research Hospital between January 1, 2015, and June 30, 2018. Composite adverse neonatal outcomes were defined as at least one of the following: 5th minute APGAR score < 7, respiratory distress syndrome (RDS), or neonatal intensive care unit (NICU) admission.

Article Synopsis
  • A 66-year-old man was hospitalized with symptoms like abdominal pain and fever, ultimately diagnosed with acute emphysematous aortitis after CT scans showed significant abnormalities in the aorta.* -
  • Despite starting antibiotic treatment, his condition worsened, leading to the discovery of a mycotic aneurysm, prompting the heart team to recommend urgent surgery, which the patient declined due to high risks.* -
  • Instead, an endovascular stent-graft was successfully implanted, the patient completed an 8-week antibiotic course, and eventually discharged in good health, highlighting the importance of recognizing aortitis in patients with specific symptoms.*

Objective: There is no study that compares the diagnostic performance of ATV and ESV techniques in detecting cleft palate. We aimed to evaluate the diagnostic accuracy of two ultrasound techniques: axial-transverse (ATV) and "equal sign" view (ESV), in detecting fetal cleft palate without cleft lip.

Patients And Methods: This prospective study was conducted from March 2019 to January 2022 in a tertiary referral hospital.

Left ventricular outflow stenosis can develop at the supravalvular, valvular, and subvalvular levels. Resection of strictures at the diffuse subvalvular level is very difficult. In such pathologies, Konno-Rastan procedure provides very successful solutions as an anterior aortoventriculoplasty method.

Background And Aim: In our study, patients who underwent isolated coronary artery bypass surgery (CABG) using Del Nido cardioplegia (DNC) and crystalloid-based cold blood cardioplegia (CBC) were compared.

Subject And Methods: In this study, two groups of patients who underwent isolated CABG using DNC (n = 106) and CBC (n = 107) were prospectively randomized. Groups were compared in terms of many results such as troponin T, returning spontaneous rhythm, and cardioplegia volume.

Background: To evaluate cases diagnosed with fetal abdominal cyst diagnosed in prenatal period.

Methods: We retrieved the cases diagnosed with fetal abdominal cyst between the years 2018 and 2020 from hospital's database. The localization, origin, dimensions, properties (simple or complex), and characteristics (solid, cystic, vascularity) were noted both in prenatal and postnatal period.

Mitral aortic intervalvular fibrosa or aorto-mitral curtain is a fibrous avascular skeletal structure located between the anterior leaflet of the mitral valve and the non-coronary and left coronary cusps of the aortic valve. Mitral and aortic valve endocarditis are rarely accompanied by mitral aortic intervalvular fibrosa pseudoaneurysm and left atrial fistula of the aorta. Pseudoaneurysm of mitral aortic intervalvular fibrosa is a fatal complication that can occur after valvular surgery, valvular endocarditis, or blunt trauma.

Objective: To investigate the predictive role of systemic immune-inflammation index (SII) on postoperative poor outcome in patients undergoing carotid endarterectomy (CEA).

Methods: A total of 347 patients undergoing elective isolated CEA between March 2010 and April 2022 were included in this multicenter retrospective observational cohort and risk-prediction study and were divided into two groups as poor outcome group ( = 23) and favorable outcome group ( = 324). Poor outcome was defined as the presence of at least one of the complications within 30 days of surgery including stroke, myocardial infarction, and death.

Objectives: Albumin undergoes structural changes under ischemia and oxidative stress, turning into ischemia-modified albumin (IMA). It has been proposed as an early biomarker for various diseases associated with ischemia. We aimed to investigate the relationship between serum IMA and peripheral artery disease (PAD) and whether it is a risk marker for the severity of PAD.

Therapeutic options for treatment of basal-like breast cancers remain limited. Here, we demonstrate that bromodomain and extra-terminal (BET) inhibition induces an adaptive response leading to MCL1 protein-driven evasion of apoptosis in breast cancer cells. Consequently, co-targeting MCL1 and BET is highly synergistic in breast cancer models.

Recent research has pointed to improved salt tolerance by co-overexpression of Arabidopsis thaliana NHX1 (Na+ /H+ antiporter) and SOS1 (Salt Overly Sensitive1). However, functionality under salt stress accompanying heat is less understood in double transgenics. To further advance possible co-operational interactions of AtNHX1 (N) and AtSOS1 (S) under combined stress, modulation of osmolyte, redox, energy, and abscisic acid metabolism genes was analysed.

Objectives: Hereditary retinal dystrophies are a rare group of diseases which are heterogeneous in genotype and phenotype and result in total blindness. One of the genetic defects that cause hereditary retinal dystrophy is mutation of the gene. Genetic therapy studies in hereditary retinal dystrophies have increased in number recently, and important developments have been reported in these studies.

Purpose: To investigate the quantitative differences in optical coherence tomography angiography (OCTA) data between type 2 diabetes patients without clinically detectable diabetic retinopathy (DR) and healthy subjects.

Methods: Thirty-nine patients with type 2 diabetes without DR and 41 age- and sex-matched healthy controls were recruited. The vessel density and foveal avascular zone (FAZ) area in the superficial capillary plexus and deep capillary plexus were measured using Nidek RS-3000 Advance® and compared between patient cohorts.

Objectives: Varicose veins that cannot be seen with the naked eye can be easily detected with Near Infrared (NIR) light. With a minimally invasive procedure performed with NIR light guided, the need for reoperation is reduced, while optimal treatment of venous insufficiency and symptoms is provided. In this study, the detection of residual varicose veins after varicose vein surgery using NIR light and the results of treatment of sclerotherapy were investigated.

Article Synopsis
  • - This study aimed to compare the effectiveness of topical cyclosporine 0.1% and bevacizumab in reducing corneal neovascularization (abnormal blood vessel growth) in a rat model.
  • - The experiment involved 30 rats divided into three groups, where one group received bevacizumab, another cyclosporine, and the last isotonic saline treatment over 28 days, followed by examinations and histopathological analysis.
  • - Results showed that while both treatments reduced inflammation and blood vessel formation, cyclosporine 0.1% was found to be more effective than bevacizumab in preventing neovascularization and improving collagen formation.
