Objective: to perform a complex ophthalmological and general examination of patients with retinal vein occlusion (RVO) and to derive classification criteria for retinal ischemia.
Materials And Methods: A total of 44 patients with RVO and macular edema and 20 controls were enrolled. All patients underwent a thorough ophthalmological and general examination and clinical laboratory testing.
Results: Cardinal risk factors of RVO development were derived from among somatic illnesses and laboratory results. Regional hemodynamics assessment helped identify the most significant systolic and diastolic blood flow disturbances in the central retinal vein and central retinal artery circulation systems. Profound changes in electrophysiological parameters were found. Statistical analysis of the collected data allowed to identify 3 stages of retinal ischemia.
Conclusion: The established risk factors of RVO development, regional blood flow impairment and original classification criteria for retinal ischemia make it possible to predict the course of the disease and treatment effect.

Department of Gerontology, CR & WISCO General Hospital, Wuhan University of Science and Technology, Wuhan, Hubei, China.
Objectives: Although patients with arthritis have significantly increased cardiovascular disease (CVD) risk, effective prediction tools remain limited. This study aimed to evaluate the predictive value of the Metabolic Score for Insulin Resistance (METS-IR) for CVD events among Chinese patients with arthritis.
Methods: Using data from the China Health and Retirement Longitudinal Study (CHARLS), we conducted a 7-year prospective cohort study (2011-2018) involving 1,059 patients with arthritis.

Purpose: Adrenocortical carcinoma (ACC) is a rare malignancy known for high rates of recurrence and poor prognosis. Previous studies revealed controversial roles of adjuvant radiation therapy (RT) in patient management. This study aimed to investigate the role of adjuvant RT in postoperative ACC patients.

Background: Acute kidney injury (AKI) is common in critically ill patients and is associated with increased morbidity and mortality. Its complications often require renal replacement therapy (RRT). Invasive mechanical ventilation (IMV) and infections are considered risk factors for the occurrence of AKI.

Purpose Of Review: Atraumatic hip pain in children is one of the most common orthopaedic complaints in this population. This review details the important elements of the pediatric hip physical exam and provides an overview of pertinent clinical exam findings in specific diagnoses of common pediatric hip pathology.
Recent Findings: A thorough physical exam is critical for the diagnosis of pediatric hip pathology, as many conditions have exam findings that are very commonly associated with the pathology, if not pathognomonic for the disorder.
Pituitary adenomas: biology, nomenclature and clinical classification.
Rev Endocr Metab Disord

Pituitary Center, Cedars-Sinai Medical Center, Los Angeles, CA, USA.
An 'adenoma' is a benign neoplasm composed of epithelial tissue, and has been standard nomenclature for primary pituitary neoplasms. In 2022, the fifth edition of the WHO Classification of Endocrine Tumours and of Central Nervous System Tumours, renamed pituitary adenomas as neuroendocrine tumours (NETs), assigning an oncology label to pituitary invariably benign neoplasms. Multidisciplinary workshops convened by the Pituitary Society have questioned the process, validity, and merit of this arbitrary change, while addressing the adverse clinical implications of the proposed new nomenclature.
