Purpose: The purpose of this study was to assess product-specific features for a variety of self-administered injection devices and identify key factors that patients and nurses in select European markets find most important when selecting injection devices for self-administration of recombinant human follicle-stimulating hormone and urinary human follicle-stimulating hormone for fertility/reproductive therapy.
Patients And Methods: Patients (N=402) in France, Italy, Spain, Germany, the UK, the Netherlands, and Belgium, as well as reproductive/fertility nurses (N=40) in Germany, Italy, France, Spain, and the Czech Republic were surveyed. All patients were previously prescribed a follicle-stimulating hormone (FSH) treatment for either in vitro fertilization or ovulation induction. Patient and nurse preferences for attributes across all injection devices in the market were obtained via an online questionnaire and evaluated using the maximum differential scaling (MaxDiff) and conjoint analyses, which captured the relative importance of the selected FSH injection device attributes to determine specific qualities in overall product preference.
Results: Both the MaxDiff and conjoint analyses indicated that, for patients and nurses, the ideal FSH injection device would be a highly accurate, multi-use reusable pen injector with a dial-back function that would be easy for both use and education/instruction. Patients and nurses each selected attributes pertinent to their own experiences with the FSH injection device. Categorically, patients valued factors that resulted in minimal impact on daily life, including reduced injection volume to minimize injection-site pain, as well as a reusable device that would be easy to use; nurses placed greater value on a device that would be easy to teach in order to instruct the greatest number of patients while minimizing risk.
Conclusion: Patient and nurse preferences were aligned on certain selected attributes of the FSH products. Although this study was an unbranded examination of attributes across all injection devices currently in the market, results demonstrated that the preferred product attributes were all characteristics of the Ovaleap Pen.

The separation and propagation of spin are vital to understanding spin-orbit coupling (SOC) in quantum systems. Exciton-polaritons, hybrid light-matter quasiparticles, offer a promising platform for investigating SOC in quantum fluids. By utilization of the optical anisotropy of materials, Rashba-Dresselhaus SOC (RDSOC) can be generated, enabling robust polariton spin transport.

Here, a "green" strategy for the simultaneous in situ synthesis of silver nanoparticles (AgNPs) during the photocrosslinking process of casein hydrogels is described. The in situ photoactivated biomineralization of AgNPs provides noticeable stability and antibacterial activity, with high photothermal effect during a sequential near-infrared laser activation.

In particular, ALD-processed SnO has demonstrated great potential as an electron transport layer in flexible perovskite solar cells (PSCs) and tandem modules. However, the poor electrical conductivities and surface wettabilities of amorphous SnO remain critical challenges for commercialization.

This study aimed to determine the influence of air abrasion on the shear bond strength (SBS) of universal adhesives when using different abrasive powders. The AquaCare Twin served as the injection device. The prepared bovine dentin specimens were air- abraded with alumina particles or bioactive glass before applying the universal adhesive (All Bond Universal, Clearfil Universal Bond Quick ER, or Scotchbond Universal Plus Adhesive).

The development of continuous-release devices or injectables for the long-term delivery of biologics is of great interest, especially monoclonal antibodies (mAbs) that require frequent, high-dose injections. Preclinical testing of these technologies in murine models is necessary for clinical translation; however, xenogeneic responses to the mAb and foreign body responses to the implants or injectables can confound results. Immune system knockout (KO) models that affect immune cells are often used in these experiments, but the effects of KO models on mAb pharmacokinetics (PK) are not well characterized.
