  • Misinformation, chiropractic, and the COVID-19 pandemic
  • 2020
  • Ingår i: Chiropractic and Manual Therapies. - : BioMed Central (BMC). - 2045-709X. ; 28:1
  • Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
    • Background: In March 2020, the World Health Organization elevated the coronavirus disease (COVID-19) epidemic to a pandemic and called for urgent and aggressive action worldwide. Public health experts have communicated clear and emphatic strategies to prevent the spread of COVID-19. Hygiene rules and social distancing practices have been implemented by entire populations, including 'stay-at-home' orders in many countries. The long-term health and economic consequences of the COVID-19 pandemic are not yet known.Main text: During this time of crisis, some chiropractors made claims on social media that chiropractic treatment can prevent or impact COVID-19. The rationale for these claims is that spinal manipulation can impact the nervous system and thus improve immunity. These beliefs often stem from nineteenth-century chiropractic concepts. We are aware of no clinically relevant scientific evidence to support such statements. We explored the internet and social media to collect examples of misinformation from Europe, North America, Australia and New Zealand regarding the impact of chiropractic treatment on immune function. We discuss the potential harm resulting from these claims and explore the role of chiropractors, teaching institutions, accrediting agencies, and legislative bodies.Conclusions: Members of the chiropractic profession share a collective responsibility to act in the best interests of patients and public health. We hope that all chiropractic stakeholders will view the COVID-19 pandemic as a call to action to eliminate the unethical and potentially dangerous claims made by chiropractors who practise outside the boundaries of scientific evidence.

  • Proteoglycan and proteome profiling of central human pulmonary fibrotic tissue utilizing miniaturized sample preparation : a feasibility study
  • 2002
  • Ingår i: Proteomics. - 1615-9861. ; 2:4, s. 394-404
  • Tidskriftsartikel (refereegranskat)abstract
    • The objective of this study was to isolate fibrotic cells from human lung biopsies taken from different central pulmonary locations. A comparison was made of cell morphology, proteoglycan- and protein-expression in mesenchymal cell cultures obtained from human bronchial biopsies from patients with asthmatic-like disorders. We isolated viable cells from 10 out of the 12 biopsies. The fibroblast-like cells were positive for the biomarker a-smooth muscle actin, indicating that the cells were in an activated state. Two different types of fibroblast-like cells were observed from human pulmonary connective tissue; one of contractile type with lamellipodia that facilitate migration and a second cell type with an increased cell size, which most likely is of a synthetic phenotype. This is the first evidence of alterations in the proteoglycan expression pattern of versican, perlecan, biglycan and decorin which can be linked to the pathophysiological state of asthmatics proven by a combination of solid-phase extraction by reversed phase and by peptide mass fingerprinting using matrix-assisted laser desorption/ionization-time of flight mass spectrometry. Protein expression analysis using two-dimensional electrophoresis was interfaced to miniaturized sample preparation techniques using microcapillary extraction. Four protein groups were identified; cytoskeletal, adhesion, scavenger and metabolic proteins. These patient's proteomes showed a high degree of heterogeneity between patients but larger homogeneity within biopsies derived from different locations of the same patient.
