Article Synopsis
  • The study examined how traditional hatchery and on-farm hatching systems affected broiler chicken performance and health during a subclinical necrotic enteritis (NE) challenge, using a 2×2 factorial design.
  • Broiler chicks from both hatching methods were analyzed for average daily gain (ADG), feed intake, and NE lesions, finding that on-farm hatched birds performed better until day 42, despite both groups being affected similarly by the NE challenge.
  • The results suggest that on-farm hatching may enhance broiler growth compared to hatchery hatching, presenting an area for further research into improving poultry health and production practices.

Increased use of genetically modified (GM) plants in the food and feed industry has raised several concerns about the presence of unwanted genes in the food chain and potential associated health risks. In recent years, several studies have compared the nutrient contents of GM crops to conventional counterparts, and some have also tracked the fate of novel DNA fragments and proteins in the gastrointestinal (GIT) and their presence in several tissues. This study was conducted to investigate the fate of transgenic PHP19340A DNA fragment containing gm-fad2-1 (Soybean Event DP-3Ø5423-1) gene in digestive tract contents, blood, internal organs, and muscle tissues.

Article Synopsis
  • The PRECISE-DAPT score, initially used to gauge bleeding risk in acute coronary syndrome (ACS) patients, can also help predict long-term mortality in those experiencing cardiogenic shock (CS).
  • A study involving 293 ACS patients found that higher PRECISE-DAPT scores were associated with an increased risk of all-cause mortality.
  • The findings suggest that the PRECISE-DAPT score could serve as a practical tool for assessing long-term survival risk in patients with ACS and CS.

Current guidelines recommend individualizing the choice and duration of P2Y inhibitor therapy based on the trade-off between bleeding and ischemic risk. However, whether a potent P2Y inhibitor (ticagrelor) or a less potent one (clopidogrel) is more appropriate in patients with acute coronary syndrome (ACS) in the setting of high bleeding or ischemic risk is not clear. The study aimed to compare the clinical outcomes of clopidogrel and ticagrelor in patients with ACS at high bleeding or ischemic risk.

Introduction: Drug-eluting stents (DES) have revolutionized percutaneous coronary intervention (PCI) by improving event-free survival compared to older stent designs. However, early-generation DES with polymer matrixes have raised concerns regarding late stent thrombosis due to delayed vascular healing. To address these issues, biologically bioabsorbable polymer drug-eluting stents (BP-DES) and polymer-free drug-eluting stents (PF-DES) have been developed.

  • Atrial fibrillation (AF) is a significant risk factor for patients with non-ST-elevation myocardial infarction (NSTEMI), and early risk stratification can help identify patients with poorer long-term outcomes.
  • The PRECISE-DAPT score is developed to predict bleeding risk in patients undergoing stent implantation and receiving dual antiplatelet therapy after percutaneous coronary intervention (PCI).
  • In a study of 526 AF patients with NSTEMI, a higher PRECISE-DAPT score, lower left ventricular ejection fraction, shorter P2Y12 inhibitor therapy duration, and a history of diabetes were linked to increased long-term all-cause mortality.

Bifurcated anatomical locations in the arterial tree, such as coronary artery bifurcations, are prone to develop obstructive atherosclerotic lesions due to the pro-atherogenic low wall shear stress. The percutaneous treatment of bifurcation lesions is among the most challenging complex coronary interventions, including different multistep stenting strategies. Even though provisional side branch (SB) stenting is recommended as the primary approach in most cases, the debate continues between provisional SB and upfront two-stent strategies, particularly in complex bifurcations consisting of a significantly diseased SB that supplies a crucial myocardial territory.

Background: White striping (WS) is a myopathy of breast muscle (Pectoralis major) that affects the quality and consumer acceptance of breast fillets of broiler chickens. Previous studies have shown that intermittent dilution of dietary nutrients suppresses the development of WS on the breast muscle of broiler chickens. However, the mechanism by which these interventions reduce the occurrence of WS remains inconclusive.

Objectives: Patients with postoperative atrial fibrillation (POAF) have increased risk of both short- and long-term mortality and morbidity; therefore, prediction of POAF is crucial in the preoperative period of the patients undergoing coronary artery bypass graft surgery. Electrocardiography (ECG) is the simplest and cost-effective tool in the preoperative workup of the patients for the prediction of POAF. A newly defined ECG parameter P wave peak time (PWPT) has been shown as a marker of atrial fibrillation development in non-surgical patients and we investigated its role in patients undergoing cardiac surgery.
