Article Synopsis
  • * A study examined 131 female patients with X-linked dominant incontinentia pigmenti (IP), finding that 36% produced autoantibodies against IFN-α and/or IFN-ω, significantly higher than age-matched controls.
  • * The presence of these autoantibodies is linked to an abnormally small thymus and predisposes patients to life-threatening viral infections, while those without these autoantibodies do not face the same risk.

  • Recent RET tyrosine kinase inhibitors (TKIs) show promise for treating RET-rearranged non-small cell lung cancer (NSCLC) and RET-mutated thyroid cancer, but resistance limits their effectiveness over time.* -
  • A CRISPR/Cas9 screening identified genes related to drug-tolerant persister cells, revealing that loss of MED12 or MIG6 increases these resistant cells and activates EGFR, leading to treatment failure.* -
  • Combining EGFR inhibitors with RET TKIs proved effective in overcoming resistance, and further experiments indicated that targeting either EGFR or RET enhances sensitivity to treatments in resistant cancer models.*

Article Synopsis
  • The screening process for systematic reviews is time-consuming, and while machine learning solutions aim to reduce this workload, they can sometimes miss relevant studies.
  • This research tested a 3-layer screening method using GPT-3.5 and GPT-4 to improve the identification of relevant literature for systematic reviews, specifically in bipolar disorder treatment studies.
  • The results showed that both AI models processed records quickly and demonstrated sensitivity levels comparable to human reviewers, suggesting they can effectively streamline the screening process without missing important studies.

  • The study emphasizes the importance of the lymphatic system in fluid balance and immune regulation, but highlights the difficulty in researching liver lymphatics due to the low abundance of lymphatic endothelial cells (LyECs) and overlapping markers with other liver cells.
  • Using single-cell RNA sequencing, the researchers identified interleukin-7 (IL7) as a unique marker for liver LyECs and developed a method to isolate these cells for further study.
  • The findings revealed distinct structural features of LyECs, such as fenestrae, and noted genetic changes in these cells during liver ischemia/reperfusion injury, enhancing the overall understanding of liver lymphatics.

Background: It is unclear how primary care physicians manage insomnia after the introduction of novel hypnotics such as orexin receptor antagonists and melatonin receptor agonists. This Web-based questionnaire survey aimed to examine treatment strategies for insomnia in Japanese primary care practice.

Methods: One-hundred-and-seventeen primary care physicians were surveyed on the familiarity of each management option for insomnia on a binary response scale (0 = "unfamiliar"; 1 = "familiar") and how they managed insomnia using a nine-point Likert scale (1 = "I never prescribe/perform it"; 9 = "I often prescribe/perform it").

Background: Colorectal cancer (CRC) is a global health concern, with advanced-stage diagnoses contributing to poor prognoses. The efficacy of CRC screening has been well-established; nevertheless, a significant proportion of patients remain unscreened, with > 70% of cases diagnosed outside screening. Although identifying specific subgroups for whom CRC screening should be particularly recommended is crucial owing to limited resources, the association between the diagnostic routes and identification of these subgroups has been less appreciated.

  • Alveolar adenoma is a rare and benign lung tumor that often appears as a solitary cystic nodule, making it hard to differentiate from other lung tumors based on imaging alone.
  • Diagnosis relies on histopathological and immunohistochemical analyses, as seen in a case study of a 50-year-old male patient who presented with chest pain and was ultimately found to have this condition after surgery.
  • Post-surgery, the patient showed no signs of malignancy or recurrence after 46 months, highlighting the generally favorable prognosis for those diagnosed with alveolar adenoma.

Unlabelled: Health effects of weekend catch-up sleep (CUS) could differ depending on both the ability to obtain sufficient sleep during weekdays and amount of weekend CUS required to compensate for sleep lost during the week. Using data from 3128 middle-aged (40-64 years) participants of the Sleep Heart Health Study, we examined the longitudinal association of these two aspects of sleep with all-cause mortality. CUS was calculated as the difference in self-reported habitual sleep duration between weekends and weekdays, and classified into no, short (1 h), and long (2 h or more) CUS.
