Objectives: Historically in medicine and beyond, the understanding of and treatment of pain is based on finding tissue injury. The fact that for chronic pain, there often is no (longer) any traceable tissue injury, in combination with the fact that pain essentially is a private experience, poses a challenge for clinical communication. This paper therefore examines how pain is linguistically and interactionally constructed as invisible.

Lay perspectives are important in the recovery of patients with nonspecific pain as they influence levels of pain and patients' pain experiences. Although previous interactional research has focused on patients' unsolicited attempts to share their perspectives, health professions also employ specific techniques to solicit them. Physiotherapists are recommended to assess lay perspectives and include them in treatment.

Article Synopsis
  • Vaccines need to encourage mucosal immunity to effectively prevent infection by respiratory viruses, but the impact of current mRNA COVID-19 vaccines on this type of immunity is not well understood.
  • A study with 183 individuals revealed that repeated mRNA booster vaccinations significantly increased neutralizing antibodies in nasal secretions, suggesting a connection between nasal and serum antibody levels.
  • Further research in a mouse model indicated that the antibodies linked to mucosal immunity come from the spleen and bone marrow and can migrate from the bloodstream to the respiratory mucosa, providing insights for future vaccine development.

Introduction: Several risk factors for revision TKA have previously been identified, but interactions between risk factors may occur and affect risk of revision. To our knowledge, such interactions have not been previously studied. As patients often exhibit multiple risk factors for revision, knowledge of these interactions can help improve risk stratification and patient education prior to TKA.

Article Synopsis
  • * Research using mouse models has shown that A20's deubiquitinase (DUB) function, when genetically disrupted, does not lead to autoimmune diseases, suggesting its role is not as straightforward as previously thought.
  • * Additionally, the absence of PAD4, which is responsible for a specific protein modification, does not prevent autoimmunity in A20-deficient mice, indicating that the pathways related to PAD4 and protein citrullination may not be crucial for the autoimmune processes in these models.

Article Synopsis
  • Improvements in COVID-19 treatments for critically ill patients need a better understanding of how the disease harms the body, particularly through the complement system, which helps fight infections but can also cause tissue damage.
  • The study finds that the alternative pathway of complement activation is mainly responsible for issues in COVID-19 and highlights differences in how lung and liver cells contribute to this response during respiratory decline.
  • Researchers identify IL-6 and STAT1/3 signaling as key triggers for complement activity and suggest that targeting complement dysregulation could improve treatment outcomes for COVID-19 patients.

Assessing primary medication nonadherence, the rate at which a medication is prescribed for a patient but is not obtained or replaced with an alternative medication within a reasonable time period, can provide a better understanding of the frequency and impact of these barriers to medication access. Previous literature has reported high rates of primary medication nonadherence, ranging from approximately 20% to 55% in patients with rheumatoid arthritis (RA) treated with specialty disease-modifying antirheumatic drugs (DMARDs). The high primary medication nonadherence rate may reflect the difficulties associated with obtaining specialty medications, such as high costs, extended prior authorizations, and pretreatment safety requirements.
