A Performance Evaluation of Convolutional Neural Network Architectures for Pterygium Detection in Anterior Segment Eye Images.

In this article, various convolutional neural network (CNN) architectures for the detection of pterygium in the anterior segment of the eye are explored and compared. Five CNN architectures (ResNet101, ResNext101, Se-ResNext50, ResNext50, and MobileNet V2) are evaluated with the objective of identifying one that surpasses the precision and diagnostic efficacy of the current existing solutions. The results show that the Se-ResNext50 architecture offers the best overall performance in terms of precision, recall, and accuracy, with values of 93%, 92%, and 92%, respectively, for these metrics.

Evaluation of automatic mixing versus manual mixing for point of care hemoglobin measurement.

Objective: We compared hemoglobin results from manually mixed blood gas (BG) Portex syringes (Smiths Medical) and automatically mixed PICO BG syringes (Radiometer Medical) measured on the ABL90 FLEX blood gas analyzer at the Point of Care with a laboratory hematology analyzer (XN-series, Sysmex) to determine whether automatic mixing improved the accuracy and precision of hemoglobin measurement relative to the standardized method.

Methods: Ninety-nine lithium heparin tubes and EDTA tubes were collected simultaneously from selected patients at five participating institutions. The lithium heparin tubes were then split between the Portex ABG syringe and the PICO aspirator.

Food Security and Obesity among Mexican Agricultural Migrant Workers.

Mexican migrant farm workers are one of the poorest and most marginalized social groups within the country. They face the double burden of malnutrition, food insecurity, as well as harsh living and labor conditions. : To examine the relationship between household food insecurity (HFI) and obesity in a population of migrant farm workers in highly modernized agribusiness areas of Northwest Mexico.

Establishing a Stand-Alone Laboratory Dedicated to the Care of Patients With Ebola Virus Disease.

Objective: To describe the process for establishment of a stand-alone laboratory dedicated to testing for Ebola virus disease (EVD).

Methods: We selected 2 neighboring rooms for the EVD unit: 1 for patient care and 1 for laboratory testing. A limited test menu was developed after consultation with the team of healthcare providers treating patients with EVD, Centers for Disease Control and Prevention (CDC) recommendations, and other sites with EVD expertise.

Shape dynamics and rheology of soft elastic particles in a shear flow.

The shape dynamics of soft, elastic particles in an unbounded simple shear flow is investigated theoretically under Stokes flow conditions. Three types of motion-steady-state, trembling, and tumbling-are predicted, depending on the shear rate, elastic shear modulus, and initial particle shape. The steady-state motion is found to be always stable.
