Emerging literature suggests contextual factors are important components of therapeutic encounters and may substantially influence clinical outcomes of a treatment intervention. At present, a single consensus definition of contextual factors, which is universal across all health-related conditions is lacking. The objective of this study was to create a consensus definition of contextual factors to better refine this concept for clinicians and researchers … MORE

The experimental research, presented in this study, focuses on athletic tests with the purpose to highlight the elastic deformations of the bones of the lower limbs, intending to verify whether the manually treated anatomical structure increases in elasticity, becoming able to accumulate more energy in the loading phase, to then release it in the final phase of the thrust. Too often neglected, the bone tissue is capable of deforming. The deformation has a key role in the cushioning and dissipation of stress, a function that is hindered in the event of fascial tension, which will consequently fall on other structures used for the same purpose (Discs, menisci, cartilage, …). Structures that, in the event of increased mechanical stress, could undergo degeneration, inflammation, and injury … MORE

Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) affects various human organ systems, including the lymphatic, pulmonary, gastrointestinal, and neurologic systems. The utilization of osteopathic manipulative treatment (OMT) techniques has been clinically effective in the alleviation of various upper respiratory infection symptoms. Consequently, the use of osteopathic manipulative medicine (OMM) in SARS-CoV-2 patients as adjunct treatment can be beneficial in promoting overall recovery. This paper attempts to address the pathophysiology of SARS-CoV-2 infection at the cellular level and its downstream effects. Subsequently, osteopathic principles were investigated to evaluate potential therapeutic effects, providing a holistic approach in the SARS-CoV-2 treatment. Although the association between the benefits of OMT on clinical improvement during the 1918 Spanish influenza pandemic can be seen, further investigation is required to establish a direct correlation between OMT and symptom management in SARS-CoV-2 … MORE

Osteoarthritis (OA) is a common, debilitating, chronic disease with no disease-modifying drug approved to date. We discovered LNA043—a derivative of angiopoietin-like 3 (ANGPTL3)—as a potent chondrogenesis inducer using a phenotypic screen with human mesenchymal stem cells. We show that LNA043 promotes chondrogenesis and cartilage matrix synthesis in vitro and regenerates hyaline articular cartilage in preclinical OA and cartilage injury models in vivo. LNA043 exerts at least part of these effects through binding to the fibronectin receptor, integrin α₅β₁ on mesenchymal stem cells and chondrocytes. In a first-in-human (phase 1), randomized, double-blinded, placebo-controlled, single ascending dose, single-center trial (NCT02491281; sponsored by Novartis Pharmaceuticals), 28 patients with knee OA were injected intra-articularly with LNA043 or placebo (3:1 ratio) either 2 h, 7 d or 21 d before total knee replacement. LNA043 met its primary safety endpoint and showed short serum pharmacokinetics, cartilage penetration and a lack of immunogenicity (secondary endpoints). Post-hoc transcriptomics profiling of cartilage revealed that a single LNA043 injection reverses the OA transcriptome signature over at least 21 d, inducing the expression of hyaline cartilage matrix components and anabolic signaling pathways, while suppressing mediators of OA progression. LNA043 is a novel disease-modifying OA drug candidate that is currently in a phase 2b trial (NCT04864392) in patients with knee OA … MORE

Previous studies document that both osteopathic physicians and third-party observers identify an approach to the patient that is consistent with the philosophy and tenets of osteopathic medicine, often without investigating whether patients identify or are satisfied with it. Osteopathic physicians and the medical education community understand the distinctiveness of an osteopathic approach to the patient. Understanding the outcomes of an osteopathic approach to patient care includes confirming whether patients experience the tenets of osteopathic medicine in physician visits and, if so, how it relates to their experience of physician empathy and satisfaction with the visit. The objectives of this study were to assess patient experience of the tenets of osteopathic medicine, physician empathy, and satisfaction with the visit and to compare the results for patients who saw DOs with those who saw MD physicians … MORE

Degenerative cervical myelopathy (DCM) is a common and disabling neurodegenerative condition. Surgical decompression is the only evidence-based treatment to halt disease progression; however, diagnosis and access to timely treatment are often delayed, which contribute to significant disability and dependence. Supporting early diagnosis and access to timely treatment is a critical priority. Exploring these challenges, Myelopathy.org has observed that people with DCM may seek osteopathy care for their symptoms, both before and after diagnosis. This study aimed to describe the current interaction between osteopaths and people with DCM and understand how this may be targeted to enhance the DCM diagnostic pathway … MORE

Intermediate (IM) band physiology in skin blood flow exhibits parallels with the primary respiratory mechanism (PRM) or cranial rhythmic impulse (CRI), controversial concepts of osteopathy in the cranial field (OCF). Owing to inconsistent manual palpation results, validity of evidence of PRM/CRI activity has been questionable. We therefore tried to validate manual palpation combining instrumented tracking and algorithmic objectivation of frequencies, amplitudes, and phases. Using a standard OCF intervention, cranial vault hold (CVH), two OCF experts palpated and digitally marked CRI frequencies in 25 healthy adults … MORE
