Integrating morphology and physiology of the key endocrine organ during tadpole development: The interrenal gland.

Indirect development is widespread in anurans and is considered an ancestral condition. The metamorphosis of larvae into juveniles involves highly coordinated morphological, physiological, biochemical, and behavioral changes, promoted by the thyroid hormone and interrenal corticosteroids. Stress response to environmental changes is also mediated by corticosteroids, affecting the timing and rate of metamorphosis and leading to great developmental plasticity in tadpoles.

Covid-19 and the Impact on Referrals to Psychiatry in those 65 years and Older.

Aim To measure the impact of Covid-19 on the mental health of those 65 years and older, referrals to psychiatry in this Emergency Department (ED) were examined. This was likely the 'tip of the iceberg' in difficulties in this cohort and may predict patterns in a future 'tsunami' of cases. Methods A review of referrals from ED in those ≥ 65 years was conducted, from April to September in 2019 and 2020.

Association Between 18-FDG Positron Emission Tomography and MRI Biomarkers of Plaque Vulnerability in Patients With Symptomatic Carotid Stenosis.

Pathologic studies suggest that unstable plaque morphology and inflammation are associated with cerebrovascular events. F-fluorodeoxyglucose positron emission tomography (FDG-PET) is a validated technique for non-invasive imaging of inflammation-related plaque metabolism, and MRI can identify morphologic features of plaque instability. The aim of this study was to investigate the association of selected imaging characteristics of plaque vulnerability measured with MRI and PET in patients with symptomatic carotid stenosis.

Eversion Endarterectomy - An Alternative Approach to Occlusive External Iliac Artery disease.

Objectives: While endovascular intervention is the recommended first option for management of common iliac artery (CIA) lesions, it lacks durable patency for Trans-Atlantic Inter-Society Consensus (TASC)-II C and D lesions involving the external iliac artery (EIA). Aorto-femoral bypass is a durable option but is unsuitable in patients with significant co-morbidities. Eversion endarterectomy provides an alternative to both endovascular and extensive open aortoiliac reconstruction for occlusive EIA disease.

Reducing the risk of venous thromboembolism following superficial endovenous treatment: A UK and Republic of Ireland consensus study.

Objectives: Venous thromboembolism is a potentially fatal complication of superficial endovenous treatment. Proper risk assessment and thromboprophylaxis could mitigate this hazard; however, there are currently no evidence-based or consensus guidelines. This study surveyed UK and Republic of Ireland vascular consultants to determine areas of consensus.
