Objective: To investigate phenotypes of comorbidity before and after an epilepsy diagnosis in a national cohort of post-9/11 Service Members and Veterans and explore phenotypic associations with mortality.

Methods: Among a longitudinal cohort of Service Members and Veterans receiving care in the Veterans Health Administration (VHA) from 2002 to 2018, annual diagnoses for 26 conditions associated with epilepsy were collected over 5 years, ranging from 2 years prior to 2 years after the year of first epilepsy diagnosis. Latent class analysis (LCA) was used to identify probabilistic comorbidity phenotypes with distinct health trajectories.

Serviço de Doenças Infeciosas, Unidade Local de Saúde Gaia/Espinho, Vila Nova de Gaia, Portugal.

Resistance to antiretroviral therapy is an increasing challenge in the management of HIV. We present the case of a woman living with HIV, with a history of multiple treatment regimens and resistances to antiretrovirals, who has been successfully treated with a combination of lenacapavir and fostemsavir for the past year, obtaining an undetectable viral load within one month of starting therapy and reporting no serious side effects. This case is amongst the first to document the combined use of lenacapivir and fostemsavir in treating multidrug-resistant HIV.

Constructing tissue/organ analogs with natural structures and cell types in vitro offers a valuable strategy for the in situ repair of damaged tissues/organs. Three-dimensional (3D) bioprinting is a flexible method for fabricating these analogs. However, extrusion-based 3D bioprinting faces the challenge of balancing the use of soft bioinks with the need for high-fidelity geometric shapes.

Zinc ions activate AKT and promote prostate cancer cell proliferation via disrupting AKT intramolecular interaction.

Oncogene

January 2025

Key Laboratory of Systems Health Science of Zhejiang Province, School of Life Science, Hangzhou Institute for Advanced Study, University of Chinese Academy of Sciences, Hangzhou, 310024, China.

Prostate is a zinc rich organ and the physiological function of the abundant zinc ions is relatively less understood. AKT kinase is a pivotal regulator downstream of cytokines, growth factors and other extracellular stimuli, and the attachment of its PH domain to PtdIns-3,4,5-P3 (PIP3) and the subsequent phosphorylation of its kinase domain by PDPK1 are considered important for its activation. Herein, we report a regulatory mechanism of AKT kinase by zinc ions.

King Abdullah University of Science and Technology, KAUST, Biological and Environmental Sciences and Engineering Division, KAUST Environmental Epigenetics Program, Thuwal, 23955-6900, Kingdom of Saudi Arabia.

Circadian rhythmicity of gene expression is a conserved feature of cell physiology. This involves fine-tuning between transcriptional and post-transcriptional mechanisms and strongly depends on the metabolic state of the cell. Together these processes guarantee an adaptive plasticity of tissue-specific genetic programs.

Article Synopsis
  • Advances in artificial intelligence (AI) are leading to increased use of data-driven algorithms in medicine, but their complex behavior renders them unreliable for clinicians, prompting the need for explainable artificial intelligence (XAI).
  • A systematic review was conducted to analyze the application of XAI in breast cancer detection and risk prediction, covering studies from January 2017 to July 2023, identifying 30 relevant peer-reviewed studies.
  • The findings indicated that SHapley Additive exPlanations (SHAP) is the most commonly used model-agnostic XAI technique in this area, particularly effective for explaining predictions from tree-based ensemble machine learning models, enhancing the transparency and trustworthiness of AI in healthcare.

Colorectal cancer (CRC) is a major cause of cancer-related death worldwide and an effective screening strategy for diagnosis of early-stage CRC is highly desired. Although extracellular vesicles (EVs) are expected to become some of the most promising tools for liquid biopsy of early disease diagnosis, the existing EV-based proteomics methods for practical application in clinical samples are limited by technical challenges in high-throughput isolation and detection of EVs. In the current study, we have developed a simplified and efficient EV-based proteomics strategy for early diagnosis of CRC.

Article Synopsis
  • The study explores how caregivers of children with cancer in Guatemala City understand illness through Explanatory Models (EMs) during clinical interactions at Unidad Nacional de Oncología Pediátrica (UNOP).
  • It involved analyzing audio recordings and interviews from caregivers to identify how the EM components—cause, occurrence, pathophysiology, course of sickness, and treatment—were discussed in the diagnostic process.
  • The findings revealed that while clinicians often initiated EM discussions, caregivers engaged with most components, particularly focusing on personal illness experiences rather than technical aspects like pathophysiology, highlighting the importance of culturally-competent communication in pediatric oncology care.

Article Synopsis
  • Circadian rhythms play a crucial role in managing cardiovascular and metabolic functions by syncing internal biological clocks with external cues like sleep and activity.
  • A disruption in these rhythms can lead to an imbalance between heart workload and energy availability, increasing the risk of heart failure (HF).
  • Adjusting these biological rhythms through lifestyle changes and targeted therapies could be a promising way to reduce heart failure issues and improve patient outcomes.
