The objective of this study was to confirm TP53 signature can predict pathological complete response (pCR) and prognosis in cohorts of breast cancer patients who received NAC in prospective studies. Development cohorts (retrospective [n = 37] and prospective [n = 216] cohorts) and validation cohorts (NAC administered prospective study cohorts [n = 407] and retrospective perioperative chemotherapy (PC)-naïve, hormone receptor (HrR)-positive cohort [PC-naïve_HrR+ cohort] [n = 322]) were used.

Prediction of heart failure events based on physiologic sensor data in HINODE defibrillator patients.

Aims: Hospitalizations are common in patients with heart failure and are associated with high mortality, readmission and economic burden. Detecting early signs of worsening heart failure may enable earlier intervention and reduce hospitalizations. The HeartLogic algorithm is designed to predict worsening heart failure using diagnostic data from multiple device sensors.

Simple prediction tools for disease progression in unvaccinated patients with mild/moderate COVID-19 aged under 65 years: Simplified DOATS and DOAT scores.

DOATS score and DOAT score, COVID-19 progression prediction tools we have developed, utilize clinical information such as presence of diabetes/obesity (DO), age (A), body temperature (T), and oxygen saturation (S). They showed good predictive power, but their scoring calculation was slightly complex, leading us to develop simplified versions. This report discusses the ability of the simplified versions to assess deterioration risk in unvaccinated, mild/moderate COVID-19 patients aged <65 years.

[A CHILD CASE OF EGOMA (PERILLA FRUTESCENS) ALLERGY DUE TO SCHOOL LUNCH, PROBABLY CAUSED BY PERCUTANEOUS SENSITIZATION].

Herein, we report the case of a 7-year-old girl with a history of atopic dermatitis because of infancy. Her grandfather grew Egoma (Perilla frutescens), and her family frequently consumed food items prepared using Egoma; however, she never consumed them because she did not enjoy these food items; she experienced vomiting, facial swelling, and oral discomfort upon ingesting Egoma during school lunch for the first time. Her food oral challenge test was positive, as well as a skin-prick test with sesame powder.
