Two-dimensional non-Hermitian skin effect in an ultracold Fermi gas.

The concept of non-Hermiticity has expanded the understanding of band topology, leading to the emergence of counter-intuitive phenomena. An example is the non-Hermitian skin effect (NHSE), which involves the concentration of eigenstates at the boundary. However, despite the potential insights that can be gained from high-dimensional non-Hermitian quantum systems in areas such as curved space, high-order topological phases and black holes, the realization of this effect in high dimensions remains unexplored.

Change in pericardial fat volume in postmenopausal women with papillary thyroid cancer undergoing thyrotropin suppressive therapy.

Background: Despite TSH suppressive therapy improve the prognosis for the patient with differentiated thyroid cancer (DTC), there is an increasing concern regarding the potentially harmful effects of lifelong TSH suppression. Therefore, we aimed to examine the changes in body composition under TSH suppression in postmenopausal women with DTC.

Methods: The body composition was assessed by the volumes as following; fat tissues of the epicardium and abdominal visceral and subcutaneous areas; bilateral psoas muscle or thigh muscle.

Use of the Superior Thyroid Artery as a Recipient Artery in Head and Neck Free Flap Reconstruction: Effects on Post-Operative Hypothyroidism.

Background: The superior thyroid artery (STA) as a recipient vessel in free flap reconstruction may theoretically impact thyroid function. This study aimed to assess whether the use of the STA has an adverse effect on thyroid function.

Methods: Retrospective review of 101 head and neck reconstructive cases.

GLP-1 Receptor Agonist Induced Eustachian Tube Dysfunction: Database and Systematic Review of Otolaryngologic Adverse Events.

Introduction: GLP-1 receptor agonists (GLP-1 RAs) have gained traction in the management of obesity. There is limited literature on the implications of GLP-1 RAs in the field of otolaryngology.

Methods: We explore the association between GLP-1 RAs with eustachian tube dysfunction (ETD) and patulous ETD (PETD) by review of cases, literature, and the FDA adverse event database (FAERS).
