Objective: With specific apparatus and surgical techniques, we have extended the use of off-pump coronary artery bypass grafting (CABG) [OPCAB] through sternotomy approach to all of the patients with multiple coronary vessel lesions necessitating CABG. The objective of this study is to assess the safety and efficacy of our technique.
Methods: All of the consecutive 100 patients with multiple coronary vessel lesions necessitating CABG underwent trans-sternal OPCAB using our innovative technique between September 2000 and December 2002. Our new technique included left pericardial traction with sternal spreader, right pericardial compression with pericardial retractor and routine use of our original coronary shunt tube.
Results: The total number of distal anastomoses was 322 and the individual grafts were to left anterior descending coronary artery branch (LAD) 127, circumflex (CX) 101 and right coronary artery (RCA) 94. The mean number of the grafts was 3.22 +/- 0.97. The conduits included left internal thoracic artery (LITA) 103, right internal thoracic artery (RITA) 29, radial artery (RA) 82, gastro-epiploic artery (GEA) 43 and saphena magna vein graft (SVG) 65. Predischarge graft angiogram showed over all patency of 99.1% (arterial graft 100% and vein graft 95.4%). Postoperative course was uneventful in all cases with no other organ failures. There was no operative or hospital death.
Conclusions: OPCAB of our technique is effective and safe. The early clinical outcome and excellent patency rates suggests its more widespread use in CABG cases.

Objectives: Contemporary studies assessing the importance of the systemic immune-inflammation index (SII) in older patients presenting with acute coronary syndrome (ACS) are scarce. This study investigated the impact and prognostic value of the SII regarding long-term mortality in older patients with ACS.
Methods: The study included 401 older patients aged 75 years and above admitted with ACS between May 2015 and December 2022.
The clinical presentation and genetic diagnosis of Tangier disease in the pediatric age group.

Division of Pediatric Neurology, Department of Pediatrics and Child Health, Erciyes University, Faculty of Medicine, Kayseri, Türkiye.
Objectives: Tangier disease (TD) is a rare autosomal recessive condition characterized by high-density lipoprotein (HDL) deficiency; involving symptoms of polyneuropathy, hyperplastic orange-yellow tonsils, vision disorder, and sudden cardiac death. The major clinical symptoms of TD may not all be co-present. This study evaluates patients diagnosed with TD in childhood to improve the possibility of early diagnosis of asymptomatic cases by reporting our patients' clinical characteristics in order to minimize delayed diagnosis and emphasize the importance of TD, easily detected by HDL measurement.

Background: Few population-based studies have assessed sex differences in stroke recurrence. In addition, contributors to sex differences in recurrence and poststroke mortality, including social factors, are unclear. We investigated sex differences in these outcomes and the contribution of social, clinical, and behavioral factors to the sex differences.

Background: Patients with end-stage kidney disease (ESKD) are at high risk for coronary artery disease. We investigate the trends and outcomes of percutaneous coronary intervention (PCI) for stable ischemic heart disease (SIHD) in patients with ESKD.
Methods: We utilized the United States Renal Data System [2010-2018] to include adult patients with ESKD on dialysis for at least 3 months who underwent PCI for SIHD.
