Antioomycete Nanoformulation for Biocontrol of English Walnut Crown and Root Rot Caused by .

In Chile and worldwide, walnut () production faces significant losses due to crown and root rot caused by the phytopathogen . Currently, control methods have proven insufficient or unfavorable for the environment, increasing the need for sustainable alternatives. This research evaluates nanoemulsions based on extracts of medicinal plants endemic to Chile to control in walnut crops.

Blood Culture Use in Medical and Surgical Intensive Care Units and Wards.

Importance: Blood culture (BC) use benchmarks in US hospitals have not been defined.

Objective: To characterize BC use in adult intensive care units (ICUs) and wards in US hospitals.

Design, Setting, And Participants: A retrospective cross-sectional study of BC use in adult medical ICUs, medical-surgical ICUs, medical wards, and medical-surgical wards from acute care hospitals from the 4 US geographic regions was conducted.

Telomere-based risk models for the early diagnosis of lung cancer.

Background: The objective of this study was to evaluate the use of telomere length measurements as diagnostic biomarkers during early screening for lung cancer in high-risk patients.

Methods: This was a prospective study of patients undergoing lung cancer diagnosis at two Spanish hospitals between April 2017 and January 2020. Telomeres from peripheral blood lymphocytes were analysed by Telomere Analysis Technology, which is based in high-throughput quantitative fluorescent in situ hybridization.

Mixed-methods multicenter assessment of healthcare workers' knowledge, perceptions, and practices related to blood culture utilization in hospitalized adults.

Objective: To understand healthcare workers' (HCWs) beliefs and practices toward blood culture (BCx) use.

Design: Cross-sectional electronic survey and semi-structured interviews.

Setting: Academic hospitals in the United States.

Electronic evaluation of infection risk from room environment and prior room occupants: the transmission from room environment events (TREE) measure.

Over a 2-year period, we identified Transmission from Room Environment Events (TREE) across the Johns Hopkins Health System, where the subsequent room occupant developed the same organism with the same antimicrobial susceptibilities as the patient who had previously occupied that room. Overall, the TREE rate was 50/100,000 inpatient days.
