To date, symptom documentation has mostly relied on clinical notes in electronic health records or patient-reported outcomes using disease-specific symptom inventories. To provide a common and precise language for symptom recording, assessment, and research, a comprehensive list of symptom codes is needed. The International Classification of Diseases, Ninth Revision or its clinical modification ( International Classification of Diseases, Ninth Revision, Clinical Modification ) has a range of codes designated for symptoms, but it does not contain codes for all possible symptoms, and not all codes in that range are symptom related. This study aimed to identify and categorize the first list of International Classification of Diseases, Ninth Revision, Clinical Modification symptom codes for a general population and demonstrate their use to characterize symptoms of patients with type 2 diabetes mellitus in the Cerner database. A list of potential symptom codes was automatically extracted from the Unified Medical Language System Metathesaurus. Two clinical experts in symptom science and diabetes manually reviewed this list to identify and categorize codes as symptoms. A total of 1888 International Classification of Diseases, Ninth Revision, Clinical Modification symptom codes were identified and categorized into 65 categories. The symptom characterization using the newly obtained symptom codes and categories was found to be more reasonable than that using the previous symptom codes and categories on the same Cerner diabetes cohort.

The global surge in the population of people 60 years and older, including that in China, challenges healthcare systems with rising age-related diseases. To address this demographic change, the Aging Biomarker Consortium (ABC) has launched the X-Age Project to develop a comprehensive aging evaluation system tailored to the Chinese population. Our goal is to identify robust biomarkers and construct composite aging clocks that capture biological age, defined as an individual's physiological and molecular state, across diverse Chinese cohorts.

Purpose: The primary objective was to investigate the trends in orbital exenteration rates at a large tertiary care center, particularly in the context of recent advancements in immunotherapy, targeted agents, and globe-sparing surgical techniques, which have significantly impacted patient management.
Methods: We conducted a retrospective cohort study at the University of Miami. Patients who underwent orbital exenterations from 2011 to 2024 were identified by obtaining surgical coding data via institutional data brokers and validated through a rigorous surgical chart review.

Background And Objectives: Myelitis is a relatively common clinical entity for neurologists, with diverse underlying causes. The aim of this study was to describe the incidence of myelitis, its causes, clinical presentation, and factors predicting functional outcomes and relapses.
Methods: Using the Swedish National Patient Registry, we identified all adult patients in Stockholm County between 2008 and 2018 using International Classification of Diseases, 10th Edition (ICD-10) codes likely to include myelitis.

Background: Appendiceal adenocarcinomas and low-grade appendiceal mucinous neoplasms (LAMNs) are rare tumours. Much of the existing knowledge is derived from registry-based studies, particularly the Surveillance, Epidemiology, and End Results database in the USA.
Methods: This retrospective cohort study used data from the Swedish Cancer Registry, Swedish Cause of Death Registry, and the National Patient Registry to analyse demographic characteristics and outcomes of patients diagnosed with appendiceal adenocarcinoma or LAMN between 2005 and 2019.

Background: Hepatitis C virus (HCV) and injection drug use among young women are dramatically rising in the rural United States. From 2004 to 2017, heroin use among non-pregnant women increased 22.4% biennially, mirroring increases in HCV cases, especially among younger populations.
