Vehicle-to-vehicle (V2V) communications are important for intelligent transportation system (ITS) development for driving safety, traffic efficiency, and the development of autonomous vehicles. V2V communication channels, environments, mobility patterns, and mobility speed significantly affect the accuracy of autonomous vehicle control. In this paper, we propose a versatile system-level framework that can be used for investigation, experimentation, and verification to expedite the development of autonomous vehicles.

Abstract: Missense-type p53 mutations have shown to acquire novel oncogenic roles through a gain-of-function mechanism. However, there is intratumor heterogeneity in stabilization of mutant p53 protein, and it has not been well understood about the interaction between p53-stabilized and -destabilized cells in the same tumors. We established mouse intestinal tumor–derived organoids carrying ApcΔ716, KrasG12D, and Tgfbr2−/− mutations with Trp53R270H or Trp53Null mutation (AKTPR270H and AKTPNull, respectively).

Article Synopsis
  • Sepsis is a major cause of hospitalizations and can lead to long-term issues like chronic muscle weakness, particularly due to mitochondrial dysfunction in survivors.
  • Researchers created a mouse model of severe sepsis to explore the link between mitochondrial abnormalities and muscle weakness, using specific treatments to observe their effects.
  • Findings indicated that muscle weakness develops over time post-sepsis, correlating with increased mitochondrial damage, suggesting that targeting these mitochondrial issues could be a potential therapeutic approach.

Article Synopsis
  • Older patients with heart failure (HF) experience a higher risk of developing pneumonia, which contributes to increased mortality rates.
  • A study of 1,266 hospitalized patients aged 65 and older found that those with low muscle strength were significantly more likely to develop pneumonia post-discharge.
  • Low muscle strength was identified as a strong predictor of pneumonia and associated with a fourfold increased risk of death after pneumonia onset.

Objectives: The Asian Working Group for Sarcopenia in 2019 (AWGS 2019) emphasized muscle mass measurements. In contrast, the Sarcopenia Definitions and Outcomes Consortium (SDOC) prioritizes functional strength and mobility. Therefore, this study aimed to compare the prognostic utility of the SDOC and AWGS 2019 criteria for all-cause mortality in older patients with heart failure.

Article Synopsis
  • The study explores the prevalence of cachexia, sarcopenia, and malnutrition in older patients with heart failure (HF) using definitions from the Asian Working Group for Cachexia (AWGC) and other criteria, finding that AWGC-defined cachexia was the most common condition.
  • Among the 861 patients analyzed, cachexia was present in 74.1%, while other conditions showed lower prevalence rates.
  • The results indicated that AWGC-defined cachexia was not significantly linked to all-cause mortality in these patients, contrasting with stronger associations found for cachexia according to Evans' criteria, sarcopenia, and malnutrition.

Article Synopsis
  • Two-step screening for colorectal cancer (CRC) begins with a fecal immunochemical test (FIT) to identify individuals who may need a follow-up colonoscopy based on their fecal hemoglobin concentration (f-Hb).
  • The study emphasizes the need to adjust the f-Hb positivity threshold in order to optimize detection rates for colorectal neoplasia while managing the number of follow-up colonoscopies required. This balance impacts clinical accuracy, colonoscopy workload, and overall effectiveness in reducing CRC incidence and mortality.
  • As non-invasive screening methods evolve, new biomarkers from various biological samples are being developed, employing machine learning for better predictive accuracy in identifying individuals at risk for CRC.
