Novel allelic variants of bla carried on IncN and IncC plasmids isolated from clinical cases in Argentina. In vivo emergence of bla.

Background: The OXA-48-like enzymes are members of the class D β-lactamases, primarily detected in Enterobacterales, with the capacity to hydrolyze carbapenems. The allelic variant bla, which has low hydrolytic activity towards carbapenemes, was detected in Argentina in 2011 and spread successfully since then, giving sporadic origin to novel local variants.

Aim: To study the phenotypic profile and the dissemination strategies of two novel OXA enzymes, bla and bla, harbored in Escherichia coli M17224 and Klebsiella pneumoniae M21014, isolated from two pediatric patients.

Proximal Muscle Resistance Training to Improve Walking in People With Multiple Sclerosis: A Pilot Study.

Background And Purpose: This pilot study examined the feasibility of a proximal muscle resistance training program to improve walking in people with multiple sclerosis using a combination of in-person, virtual, and independent exercise sessions.

Methods: People with multiple sclerosis (Expanded Disability Status Scale Score is <6.0) were recruited to a study of resistance training exercises targeting hip abduction and trunk muscles for 10 weeks.

Online Patient Education in Obstructive Sleep Apnea: ChatGPT versus Google Search.

The widespread implementation of artificial intelligence technologies provides an appealing alternative to traditional search engines for online patient healthcare education. This study assessed ChatGPT-3.5's capabilities as a source of obstructive sleep apnea (OSA) information, using Google Search as a comparison.

Fiber-optic seismic sensing of vadose zone soil moisture dynamics.

Vadose zone soil moisture is often considered a pivotal intermediary water reservoir between surface and groundwater in semi-arid regions. Understanding its dynamics in response to changes in meteorologic forcing patterns is essential to enhance the climate resiliency of our ecological and agricultural system. However, the inability to observe high-resolution vadose zone soil moisture dynamics over large spatiotemporal scales hinders quantitative characterization.

Young Women with Early-Stage Breast Cancer Treated with Upfront Surgery: Overview of Oncological Outcomes.

: Breast cancer in young women aged < 40 years is rare and often aggressive with less favorable survival rates. The lack of systematic screening, later stage at diagnosis, and a more aggressive disease biology may all contribute to their poor prognosis. Data on the best management remain conflicting, especially those regarding surgical management, either breast-conserving or mastectomy.
