We employed a mechanistic learning approach, integrating on-treatment tumor kinetics (TK) modeling with various machine learning (ML) models to address the challenge of predicting post-progression survival (PPS)-the duration from the time of documented disease progression to death-and overall survival (OS) in Head and Neck Squamous Cell Carcinoma (HNSCC). We compared the predictive power of model-derived TK parameters versus RECIST and assessed the efficacy of nine TK-OS ML models against conventional survival models. Data from 526 advanced HNSCC patients treated with chemotherapy and cetuximab in the TPExtreme trial were analyzed using a double-exponential model.

Background: Elevated low-density lipoprotein cholesterol is a risk factor for atherosclerotic cardiovascular disease, including acute ischemic stroke (AIS), due to large- and small-vessel disease. Cholesterol management guidelines recommend lipid-lowering therapy (LLT) to prevent atherosclerotic cardiovascular disease events. This study assessed use of LLT at the time of AIS according to guideline recommendations and determined the association of prestroke LLT use with stroke severity.

Article Synopsis
  • A study called IMADGIST assessed whether extending adjuvant imatinib treatment for an additional three years (totaling six years) improved disease-free survival in patients with high-risk localized gastrointestinal stromal tumors (GIST) who had already received three years of treatment after surgery.
  • Conducted across 14 centers, the trial included 136 patients with varied risks of tumor recurrence, finding that those treated for six years had significantly better disease-free survival compared to those who stopped after three years.
  • Although there was no significant difference in overall survival, time to imatinib resistance, or quality of life between the two groups, the results suggest that extending treatment can effectively lower relapse rates with

Article Synopsis
  • - Neurocysticercosis is a significant parasitic disease, and diagnosing it often requires neuroimaging, which can be hard to access in poor rural areas.
  • - A new, quick point-of-care (POC) test was developed to detect urinary antigens, improving diagnosis by identifying individuals who need further imaging.
  • - The POC assay showed a 73.6% overall agreement with the standard Ag-ELISA, performing especially well in nonreactive and positive sample groups, making it a practical and noninvasive option for community screening.

Multiplexed spatial profiling of mRNAs has recently gained traction as a tool to explore the cellular diversity and the architecture of tissues. We propose a sensitive, open-source, simple and flexible method for the generation of in situ expression maps of hundreds of genes. We use direct ligation of padlock probes on mRNAs, coupled with rolling circle amplification and hybridization-based in situ combinatorial barcoding, to achieve high detection efficiency, high-throughput and large multiplexing.

Article Synopsis
  • - Early-stage anal squamous cell carcinomas (ASCC) are typically treated with chemoradiotherapy (CRT), but the study suggests that radiotherapy (RT) alone may provide similar effectiveness with reduced side effects.
  • - The research included 440 patients, with no significant differences in three-year disease-free survival, overall survival, or colostomy-free survival between those treated with CRT and RT.
  • - Patients receiving CRT experienced more treatment interruptions and higher levels of severe toxicities compared to those receiving RT, implying that CRT may be less favorable due to increased toxicity and longer treatment times.

Article Synopsis
  • - Researchers studied how living in disadvantaged neighborhoods over a lifetime affects health, using data from 4,177 adults in Wisconsin to assess neighborhood conditions.
  • - They developed four methods to evaluate cumulative neighborhood disadvantage and found that issues like transportation limits, residential turnover, education gaps, and racial segregation are linked to poorer self-reported health.
  • - The study reveals that considering long-term neighborhood exposure provides a clearer understanding of health risks than relying on a single point-in-time assessment, suggesting the need for a life course perspective in health research.

Embryonic development is a complex and dynamic process that unfolds over time and involves the production and diversification of increasing numbers of cells. The impact of developmental time on the formation of the central nervous system is well documented, with evidence showing that time plays a crucial role in establishing the identity of neuronal subtypes. However, the study of how time translates into genetic instructions driving cell fate is limited by the scarcity of suitable experimental tools.

Introduction: Communication in a doctor-patient relationship constitutes a crucial aspect in medicine, and its multiple dimensions encompass a wide variety of ethical issues. Communication is particularly relevant in oncology, because it requires continually dealing with sensitive topics in one of the most highly vulnerable situations as a human: illness and proximity to death. Sexuality is one of these topics because it constitutes an area that is frequently affected by cancer and cancer treatment, which may include causing significant distress, the reinforcement of a negative self-image, relationship conflicts and a permanent memory of having cancer.

Liver sinusoidal endothelial cells (LSECs) play a crucial role in maintaining liver microcirculation and exchange of nutrients in the liver and are thought to be involved in the pathogenesis of metabolic dysfunction-associated steatotic liver disease (MASLD). The activation of hepatic stellate cells (HSCs) and Kupffer cells (KCs) has been considered to be responsible for the onset of liver fibrosis and the aggravation of liver injury. However, the paracrine regulatory effects of LSECs in the development of MASLD, in particular the role of LSEC-derived extracellular vesicles (EVs) remains unclear.
