Background: Contamination of sterilized surgical instruments is not a typically suspected source of increased infection rate, especially if no abnormalities in the sterilization process are detected.
Purpose/hypothesis: The purpose of this study was to report increased infection rates after knee ligament reconstructions due to undetectable sterilization process errors leading to residual moisture, not limited to a specific surgical tool. It was hypothesized that (1) residual moisture on surgical tools due to autoclave overloading would not be detected by autoclave self-diagnostics, chemical and biological tests, or organoleptic assessment and (2) this kind of contamination may elevate infection rates, especially in knee intra-articular reconstruction procedures.

Dissolved oxygen is crucial for metabolism, growth, and other complex physiological and pathological processes; however, standard physiological models (such as organ-on-chip systems) often use ambient oxygen levels, which do not reflect the lower levels that are typically found . Additionally, the local generation of reactive oxygen species (ROS; a key factor in physiological systems) is often overlooked in biology-mimicking models. Here, we present a microfluidic system that integrates electrochemical dissolved oxygen sensors with lab-on-a-chip technology to monitor the physiological oxygen concentrations and generate hydrogen peroxide (HO; a specific ROS).

Background: The advantages of electronic health records (EHRs) are well-documented regarding the process of care, enhanced data accessibility and cost savings. However, EHR design can also contribute to usability challenges, with poorly designed EHRs being implicated in user errors including patient overdoses. Our study seeks to evaluate how EHR design influences both usability and medication safety.

Background: Delirium is a common symptom following a traumatic brain injury (TBI) that is often overlooked by healthcare professionals. Early detection of post-traumatic delirium is crucial to improving patient outcomes and quality of life. The four As Test (4AT: alertness, attention, abbreviated mental test-4, and acute mental changes) is a brief and rapid tool for delirium assessment with acceptable reliability and validity.

Non-alcoholic fatty liver disease (NAFLD) is a disease closely associated with metabolic abnormalities. Lipid droplets (LDs) serve as organelles that store intracellular neutral lipids and maintain cellular energy homeostasis. Their abnormalities can cause metabolic disorders and disease, which is also one of the distinctive characteristics of NAFLD patients.
