Fiber optics-based surface enhanced Raman Spectroscopy sensors for rapid multiplex detection of foodborne pathogens in raw poultry.

A new high-sensitivity, low-cost, Surface Enhanced Raman Spectroscopy (SERS) sensor allows for the rapid multiplex detection of foodborne pathogens in raw poultry. Self-assembled microspheres are used to pattern a hexagonal close-packed array of nanoantennas onto a side-polished multimode fiber core. Each microsphere focuses UV radiation to a photonic nanojet within a layer of photoresist on the fiber which allows the nanoantenna geometry to be controlled.

Comparative study of immunoassays, a microelectromechanical systems-based biosensor, and RT-QuIC for the diagnosis of chronic wasting disease in white-tailed deer.

Background: Chronic wasting disease (CWD) is a fatal transmissible spongiform encephalopathy in cervids. The disease is caused by a pathogenic prion, namely PrP. Currently, diagnosis of CWD relies on IHC detection of PrP in the obex or retropharyngeal lymph nodes (RPLN) or ELISA screening of obex and RPLN followed by IHC confirmation of positive results.

All-Arthroscopic Matrix-Associated Autologous Chondrocyte Implantation for a Trochlear Defect.

Matrix-associated autologous chondrocyte implantation (MACI) is a 2-step technique designed to treat symptomatic full-thickness articular cartilage defects of the knee. In this technique article, MACI (autologous cultured chondrocytes on porcine collagen membrane) is used to treat a femoral trochlear defect of the knee. Treating a defect with this technique leads to improved clinical outcomes by restoring the native chondral surface architecture and biomechanics of the knee.

Clinical Commentary: A Criteria-Based Testing Protocol for Return to Sport Post Hip Arthroscopy for Impingement.

Unlabelled: Overall, 84%-87% of athletes will return to sport following hip arthroscopy; however, some literature suggests that only 57% of athletes return to their preinjury level, and only 16.9% report optimal performance. This discrepancy may be due to a lack of consistency within the definition of return to sport as well as a lack of consistency within rehabilitation programs when determining return to sport readiness.

A microfluidic biosensor for the diagnosis of chronic wasting disease.

Cervids are affected by a neurologic disease that is always fatal to individuals and has population effects. This disease is called chronic wasting disease (CWD) and is caused by a misfolded prion protein. The disease is transmitted via contact with contaminated body fluids and tissue or exposure to the environment, such as drinking water or food.

A microfluidic biosensor architecture for the rapid detection of COVID-19.

The lack of enough diagnostic capacity to detect severe acute respiratory syndrome coronavirus 2 (SARS-COV-2) has been one of the major challenges in the control the 2019 COVID pandemic; this led to significant delay in prompt treatment of COVID-19 patients or accurately estimate disease situation. Current methods for the diagnosis of SARS-COV-2 infection on clinical specimens (e.g.

Editorial Commentary: Hip Arthroscopy Outcomes in Older Patients Can Equal Outcomes in Younger Patients With Proper Surgical Indications.

Hip arthroscopy patients often present with clinical features that help broadly categorize them as the younger patient with femoroacetabular impingement, the microinstability- or instability-related patient, those patients with predominant peripheral compartment disease, and the older patient with femoroacetabular impingement plus peripheral compartment disease. Outcomes in older patients can equal outcomes in younger patients with proper surgical indications. Specifically, older hip arthroscopy patients do well in the absence of degenerative articular cartilage changes.

Inverted appendix in a patient with colon cancer: a case report and long-term follow-up.

Appendiceal inversion is a rare entity that can potentially mimic serious pathology and provide diagnostic uncertainty. They are mostly diagnosed intraoperatively or during endoscopies and scans for other reasons. We report a case of an asymptomatic patient treated for colon cancer without previous history of appendectomy.

Uncooled two-microbolometer stack for long wavelength infrared detection.

We have investigated an uncooled infrared (IR) detector utilizing a dual level architecture. This was achieved by combining two-microbolometer stack in the vertical direction to achieve high IR absorption over two distinct spectral windows across the long wavelength infrared region (LWIR). In addition, we have studied amorphous silicon germanium oxide (SiGeO) as an IR sensitive material, and metasurface to control IR absorption/reflection in interaction with standard Fabry-Perot cavity.

ASIS Avulsion Fracture Repair with Lag Screw and Tape Bridge Construct.

An anterior superior iliac spine avulsion (ASIS) is an injury that is induced by a rapid contraction of the sartorius and tensor fascia lata (TFL) muscles in the thigh. In this technique article, the ASIS is repaired by restoring normal length and tension to the sartorius muscle-tendon unit, which optimizes anatomic healing and function of the hip. We recommend a hybrid fixation strategy.

Addressing Arthroscopic-Assisted Acromioclavicular Joint Reconstruction in the Beach Chair Position With Concomitant Labral Pathology in the Lateral Decubitus Position.

High-grade Acromioclavicular (AC) injuries are complete dislocations, involving ruptures of the AC and coracoclavicular ligaments. They occur following trauma after a fall, direct-blow to an adducted arm, or indirectly by falling onto an abducted, outstretched extremity. Given this traumatic etiology, additional intra-articular pathologies can arise and may go unnoticed because of the painful and prominent AC joint (ACJ).

Reverse shoulder arthroplasty in patients 85 years and older is safe, effective, and durable.

Background: Reverse shoulder arthroplasty (RSA) was originally indicated for older adults, but outcomes in the oldest patients have not been studied. The purpose of this study was to report on patients aged ≥85 years undergoing RSA. We hypothesized that RSA would be safe, effective, and durable.

Off-axis microsphere photolithography patterned nanohole array and other structures on an optical fiber tip for glucose sensing.

Microsphere photolithography (MPL) using off-axis UV exposure is a technique that uses a layer of self-assembled microspheres as an optical mask to project different periodic nanopatterns. This paper introduces MPL as an alternative fabrication technique to pattern complex metasurfaces on an optical single mode fiber tip as a sensor for measuring refractive index. Based on the hexagonal close packing microsphere array, complicated metasurfaces were successfully created by changing the UV illumination angle.
