Exploring the factors associated with prelacteal feeds in Papua New Guinea: a population-based survey.

Background: Prelacteal feeding disrupts early breastfeeding initiation and exclusive breastfeeding, and increases the risk of childhood illnesses and under-five mortality. Despite its negative health outcomes, newborns are given prelacteal feeds in Papua New Guinea (PNG). This study investigated the factors associated with prelacteal feeding practices among women in PNG.

Dexmedetomidine and surgical field visibility in nasal surgery: A systematic review and meta-analysis.

Introduction: Nasal and sinus surgery, especially using endoscopy, relies upon adequate haemostasis to be safe and effective. Often other haemostatic methods, such as cautery are not viable, and other methods must be employed. This study examines the effectiveness of dexmedetomidine in controlled hypotension and for surgical field visibility in endoscopic sinus surgery and other nasal surgeries.

Normalizing arterial blood pressure in patients with aortic stenosis does not prevent grading discrepancies between pre-cardiopulmonary bypass transesophageal echocardiography and transthoracic echocardiography.

Background: Aortic stenosis (AS) grading discrepancies exist between pre-cardiopulmonary (pre-CPB) transesophageal echocardiography (TEE) and preoperative transthoracic echocardiography (TTE). Prior studies have not systematically controlled blood pressure.

Aims: We hypothesized that normalizing arterial blood pressure during pre-CPB TEE for patients undergoing valve replacement for AS would result in equivalent grading measurements when compared to TTE.
