Background: Mid-infrared spectral technology has shown a high degree of promise in detecting glucose in plasma. OptiScan Biomedical has developed a glucose monitor based on mid-infrared spectroscopy that withdraws blood samples and measures plasma glucose. The objective of this study was to evaluate the accuracy and performance of the OptiScanner™ 5000 system on different pools of blood.
Methods: This study was performed to validate the blood glucose measurements obtained with the OptiScanner™ 5000 by comparing them to Central Laboratory glucose measurements (VITROS® 5600 Integrated System) as a comparative method across a broad range of glucose values over a three day period to obtain 80-90 paired measurements.
Results: A total of 81 paired measurements, distributed between 33 and 320mg/100mL of glucose, were performed. The aggregate data points were within International Organization for Standardization standards, with 100% of the glucose values within ±15%.
Conclusions: The current study suggests that a mid-IR fixed-wavelength system (OptiScanner) can measure glucose accurately across a wide range of glucose values in plasma of ICU patients.

Background: Total pancreatectomy and intraportal islet cell auto transplantation (TPIAT) is increasingly being offered to patients with refractory chronic pancreatitis. Understanding factors that impact islet function over time is critical.
Study Design: We evaluated factors associated with islet function over 12 years post TPIAT using mixed meal tolerance testing (MMTT).

Glycogen storage disease type IV (GSD IV) is a rare disease caused by a defect in glycogen branching enzyme 1 (GBE1), which played a crucial role in glycogen branching. GSD IV occurs once in approximately 1 in every 760,000 to 960,000 live births and is inherited in an autosomal recessive pattern. Early diagnosis of GSD IV is challenging due to non-specific symptoms, such as liver and spleen enlargement, which can overlap with other hematologic and hepatobiliary disorders.

Background: Kidney transplantation (kTx) is by far the most effective method of treating end-stage renal disease, with immunosuppressive therapy being obligatory for all, except identical twins. Despite kTx being the most effective treatment for end-stage renal disease, the patients face significant morbidity. They are often burdened with diabetes, anaemia, lipid disorders, all of which pose heightened risks for cardiovascular disease.

Objectives: Knee braces were introduced to sports 30 years ago. However, knee brace use for non-contact anterior cruciate ligament injury prevention intervention remains contentious due to concerns about performance hindrances. Since knee brace use is a potential modifiable risk factor, we aimed to investigate the effect of discounting and continued functional knee brace (FKB) on lower extremity power-vertical jump (VJ), acceleration, speed, and agility performance.

The impact of the laser wavelength on accuracy in elemental composition analysis in atom probe tomography (APT) was investigated. Three different commercial atom probe systems - LEAP 3000X HR, LEAP 5000 XR, and LEAP 6000 XR - were systematically compared for a TiN model coating studying the effect of shorter laser wavelengths, especially in the deep ultraviolet (DUV) range, on the evaporation behavior. The findings demonstrate that the use of shorter wavelengths enhances the accuracy in elemental composition, while maintaining similar electric field strengths.
