Detection of Viable but Nonculturable E. coli Induced by Low-Level Antimicrobials Using AI-Enabled Hyperspectral Microscopy.

Rapid detection of bacterial pathogens is essential for food safety and public health, yet bacteria can evade detection by entering a viable but nonculturable (VBNC) state under sublethal stress, such as antimicrobial residues. These bacteria remain active but undetectable by standard culture-based methods without extensive enrichment, necessitating advanced detection methods. This study developed an AI-enabled hyperspectral microscope imaging (HMI) framework for rapid VBNC detection under low-level antimicrobials.

Patients submitted to re-revision ACL reconstruction present more knee laxity, more complications, and a higher failure rate than patients submitted to the first revision ACL reconstruction.

Background: Few comparative studies have evaluated patients who underwent two revision anterior cruciate ligament reconstruction (ACLR) and patients who underwent one revision ACLR, and many of them have a short postoperative follow-up and a relatively small number of patients. The objective of this study is to evaluate the functional results, complications, and failure rates of patients who underwent one revision ACLR and patients who underwent two revision ACLRs.

Methods: This is a retrospective study comparing patients who underwent one revision ACLR (Group 1) with patients who underwent a re-revision ACLR (Group 2).

Recovery of Full Hyperextension After Anterior Cruciate Ligament Reconstruction Is Associated With Better Functional Outcomes but Greater Anterior Cruciate Ligament-Related Laxity After a Minimum 24-Month Follow-Up.

Purpose: To evaluate patients who had anterior cruciate ligament (ACL) reconstruction with preoperative hyperextension and compare physical examination (KT-1000 and pivot shift) and patient-reported outcome measures of patients who recovered the entire hyperextension with patients who did not.

Methods: Patients aged 18 to 60 years with more than 5° of knee hyperextension who had anatomic ACL reconstruction with any graft from June 2013 to June 2021 and at least a 24-month follow-up were evaluated retrospectively. Hamstrings and patellar tendon grafts were fixed around 20° to 30° of flexion and in full extension, respectively.

Real-time management of intra-hospital patient transport requests.

This paper addresses the management of patients' transportation requests within a hospital, a very challenging problem where requests must be scheduled among the available porters so that patients arrive at their destination timely and the resources invested in patient transport are kept as low as possible. Transportation requests arrive during the day in an unpredictable manner, so they need to be scheduled in real-time. To ensure that the requests are scheduled in the best possible manner, one should also reconsider the decisions made on pending requests that have not yet been completed, a process that will be referred to as rescheduling.

Comparative study of patients with midshaft clavicle fracture fixed with a locked plate via an open versus percutaneous approach.

Objective: To compare the results of surgical treatment of midshaft clavicle fractures, treated with the technique of minimally invasive plate osteosynthesis (MIPO) with locking compression plate versus open reduction and internal fixation (ORIF) with locked plate.

Methods: Quasi-randomized comparative study, evaluating displaced midshaft clavicle fractures treated with MIPO versus ORIF, with procedures performed by a single surgeon. We evaluated patients at 12 months using the University of California at Los Angeles (UCLA) scale and radiographically at 8, 12, 26 and 52 weeks, in addition to describing complications.
