Composite Hyaluronic Acid Gas-Entrapping Materials to Promote Wound Healing.
Biomacromolecules
January 2025
Department of Biomedical Engineering, University of Iowa, Iowa City, Iowa 52242, United States.
Tissue repair is often impaired in pathological states, highlighting the need for innovative wound-healing technologies. This study introduces composite hyaluronic acid gas-entrapping materials (GEMs) delivering carbon monoxide (CO) to promote wound healing in pigs. These composite materials facilitate burst release followed by sustained release of CO over 48 h.

Background: RYDG is the second most prevalent bariatric operation worldwide in terms of surgical treatment for the management of obesity and its comorbidities; however, one of its complications is the development of Petersen's space hernia. Currently there is no specific cause for their development since, based on studies published worldwide, they have an unpredictable behavior in each individual.
Objective: To establish the prevalence of Petersen's hernia and risk factors for its development.
Petersen's space hernia as an immediate complication in a patient undergoing gastric bypass: a case report.

Petersen's space hernias are common internal hernias following laparoscopic gastric bypass surgery, occurring when intestinal loops protrude through the space between the mesentery of the alimentary limb and the transverse mesocolon. A 43-year-old female with a history of hypertension underwent a revisional Roux-en-Y gastric bypass due to weight regain and severe gastroesophageal reflux disease. Postoperatively, she developed abdominal pain, and an urgent diagnostic laparoscopy was performed, revealing a nearly complete herniation of the alimentary limb through Petersen's mesenteric defect.

Objective: Lengthening of the quadriceps tendon for dehiscence in chronic rupture.
Indications: Chronic rupture of the quadriceps tendon with delayed diagnosis or failure of primary refixation with a dehiscence between 1 and 5 cm.
Contraindications: Dehiscence of more than 5 cm.
Efficacy of four different left atrial appendage closure techniques during cardiac surgery-A transesophageal echocardiography follow-up study.

Department of Cardiovascular Surgery, University Heart and Vascular Center Hamburg, Hamburg, Germany.
Objective: Closure of the left atrial appendage (LAA) is a routine part of atrial fibrillation ablation surgery and significantly reduces stroke rates. Different LAA-closure techniques are used in cardiac surgery with variable results reported. We therefore evaluated the efficacy of 4 different LAA-closure techniques in patients undergoing cardiac surgery.
