Fraudulent Participation in Online Qualitative Studies: Practical Recommendations on an Emerging Phenomenon.

Fraudulent participation is defined in the following as participation in research by individuals who, for one reason or another, intentionally provide false responses. Qualitative studies are at an increased risk of fraudulent participation when online recruitment and participation are used, and monetary incentives offered. Fraudulent participation threatens data quality and subsequent evidence-based practice, yet validated guidance on how to tackle it is lacking.

[REGENERATIVE MEDICINE IN ORTHOPEDICS - UPDATES AND COMMON USES].

Regenerative medicine is a medical field that aims to heal, rehabilitate, repair, and facilitate the regeneration of diseased and damaged cells, tissues and organs. Regenerative medicine is based on mobilizing the body's self-healing abilities. The use of regenerative medicine to treat various musculoskeletal conditions is an evolving field within orthopedics and sports medicine called 'ortho-biology' or 'ortho-regenerative medicine'.

Establishment of CORONET, COVID-19 Risk in Oncology Evaluation Tool, to Identify Patients With Cancer at Low Versus High Risk of Severe Complications of COVID-19 Disease On Presentation to Hospital.

Purpose: Patients with cancer are at increased risk of severe COVID-19 disease, but have heterogeneous presentations and outcomes. Decision-making tools for hospital admission, severity prediction, and increased monitoring for early intervention are critical. We sought to identify features of COVID-19 disease in patients with cancer predicting severe disease and build a decision support online tool, COVID-19 Risk in Oncology Evaluation Tool (CORONET).

In Vitro 3D Cultures to Reproduce the Bone Marrow Niche.

Over the past century, the study of biological processes in the human body has progressed from tissue culture on glass plates to complex 3D models of tissues, organs, and body systems. These dynamic 3D systems have allowed for more accurate recapitulation of human physiology and pathology, which has yielded a platform for disease study with a greater capacity to understand pathophysiology and to assess pharmaceutical treatments. Specifically, by increasing the accuracy with which the microenvironments of disease processes are modeled, the clinical manifestation of disease has been more accurately reproduced in vitro.

Effective Combination of Innate and Adaptive Immunotherapeutic Approaches in a Mouse Melanoma Model.

Most cancer immunotherapies include activation of either innate or adaptive immune responses. We hypothesized that the combined activation of both innate and adaptive immunity will result in better antitumor efficacy. We have previously shown the synergy of an agonistic anti-CD40 mAb (anti-CD40) and CpG-oligodeoxynucleotides in activating macrophages to induce tumor cell killing in mice.
