Background Objectives: Scrub typhus is an acute febrile zoonotic disease caused by the obligate intracellular gram-negative bacteria Orientia tsutsugamushi. Growing data over the last few years on the Indian subcontinent suggest that it is one of the most widespread but under-reported diseases. The study aimed to document the clinical and paraclinical profile and evaluate complications of scrub typhus in severe and nonsevere pediatric age groups.

Introduction: Malnutrition among older adults continues to be a prevalent health concern. While literature has highlighted an increased risk of malnutrition mortality for adults older than 65 y, the age threshold at which malnutrition effects survival and mortality remains unexplored.

Methods: Annual crude and age-adjusted malnutrition-related mortality data from 2009 to 2018 was extracted from the Centers for Disease Control and Prevention Wide-Ranging Online Data for Epidemiologic Research database.

Zebularine-treated wheat uncovered a phenotype with characteristics of an epigenetically regulated trait, but major chromosomal aberrations, not DNA methylation changes, are the cause, making zebularine unsuitable for epigenetic breeding. Breeding to identify disease-resistant and climate-tolerant high-yielding wheats has led to yield increases over many years, but new hardy, higher yielding varieties are still needed to improve food security in the face of climate change. Traditional breeding to develop new cultivars of wheat is a lengthy process taking more than seven years from the initial cross to cultivar release.

Background: Motor vehicle collisions (MVC) continue to be a leading cause of mortality for youth in the United States. Since 2010, seven states have revoked mandatory laws that suspended licenses for underage alcohol use, also known as use/lose laws. This study analyzed whether each state's policy change was associated with increased youth MVC mortality.

Background: In HER2+ early breast cancer (EBC), we investigated tumor and immune changes during neoadjuvant treatment and their impact on residual disease (RD) biology and prognostic implications across 4 neoadjuvant studies of trastuzumab with or without lapatinib, and with or without chemotherapy: CALGB 40601, PAMELA, NeoALTTO and NSABP B-41.

Patients And Methods: We compared tumor and immune gene expression changes during neoadjuvant treatment and their association with with event-free survival (EFS) by uni- and multivariable Cox regression models in different cohorts and timepoints: 452 RD samples at baseline including 169 with a paired RD, and biomarker changes during neoadjuvant therapy, evaluating model performance via the c-index.

Results: Analysis of 169 paired tumor samples revealed a shift in intrinsic subtype proportions from HER2-Enriched at baseline (50.
