FZD5 controls intestinal crypt homeostasis and colonic Wnt surrogate agonist response.

The rapidly regenerating intestinal epithelium requires crypt intestinal stem cells (ISCs). Wnt/β-catenin signaling maintains crypt homeostasis and Lgr5+ ISCs, and WNT ligands bind Frizzled receptors (FZD1-10). Identifying specific FZD(s) essential for intestinal homeostasis has been elusive; however, bioengineered antagonists blocking Wnt binding to FZD5 and FZD8 deplete the gut epithelium in vivo, highlighting potential roles.

Recovery and Resilience in the Canal Community: Economic Impacts and Solutions During the COVID-19 Pandemic.

Background: Public health pandemics, such as COVID-19, not only impact the physical health and wellbeing of communities but also often have far-reaching effects on their social, psychological, environmental, and economic welfare. The coronavirus pandemic has highlighted the significant inequities experienced among those who are Black, Indigenous, and People of Color (BIPOC), especially in the areas of housing instability, unemployment, and debt accrual. This study investigates the socioeconomic impacts of COVID-19 on residents of the Canal neighborhood ("The Canal"), a low-income Latinx community in Marin County, California.

Genomic analysis of high copy-number sequences for the targeted detection of Listeria species using a flow-through surveillance system.

The bacterial foodborne pathogen Listeria monocytogenes has been implicated in fresh produce outbreaks with a significant economic impact. Given that L. monocytogenes is widespread in the environment, food production facilities constantly monitor for the presence of Listeria species.

A global point prevalence survey of antimicrobial use in neonatal intensive care units: The no-more-antibiotics and resistance (NO-MAS-R) study.

Background: Global assessment of antimicrobial agents prescribed to infants in the neonatal intensive care unit (NICU) may inform antimicrobial stewardship efforts.

Methods: We conducted a one-day global point prevalence study of all antimicrobials provided to NICU infants. Demographic, clinical, and microbiologic data were obtained including NICU level, census, birth weight, gestational/chronologic age, diagnoses, antimicrobial therapy (reason for use; length of therapy), antimicrobial stewardship program (ASP), and 30-day in-hospital mortality.

Simulation-Based Structured Education Supports Focused Neonatal Cranial Ultrasound Training.

Objectives: Brain injury in preterm neonates may cause clinical deterioration and requires timeous bedside diagnosis. Teaching cranial ultrasound (US) skills using fragile preterm neonates is challenging. The purpose of this study was to test the effectiveness and feasibility of using task-trainer computer-based simulators and US-suitable cranial phantoms in combination with teaching sessions in teaching novices to perform focused cranial US evaluations for identifying substantial intraventricular hemorrhage.

Latino immigration: Preparing school psychologists to meet students' needs.

As the population of immigrant Latino students continues to rise, school psychologists serving Latino children and families must develop the knowledge and skills necessary to provide high-quality psychological services to culturally and linguistically diverse students from immigrant families. Following a review of the relevant literature on the educational, social, and emotional needs of immigrant Latino children, we describe Project SUPERB (Scholars Using Psychology and Education to Reach Bilinguals), a grant-funded initiative to address the shortage of bilingual (Spanish-English) school psychologists. We discuss important issues regarding training and preparation to develop the competencies necessary for effective assessment, intervention, and collaboration in the context of school settings to help immigrant children achieve success.
