Evaluation of Financial and Non-financial Conflicts of Interest and Quality of Evidence underlying Psoriatic Arthritis Clinical Practice Guidelines-Analysis of Personal Payments from Pharmaceutical Companies and Authors' Self-citation Rate in Japan and the United States
OBJECTIVE: To assess financial conflict of interest (FCOI) and non-financial conflicts of interest (NFCOI) among psoriatic arthritis clinical practice guideline (PsACPG) authors in Japan and US, and to evaluate the quality of evidence and strength of recommendations of PsACPG.METHODS: We performed a retrospective analysis using payment data from major Japanese pharmaceutical companies and the US Open Payments Database from 2016 to 2018. All authors of PsACPG issued by Japanese Dermatological Association (JDAPsACPG) and American College of Rheumatology (ACRPsACPG) were included.RESULTS: Of 23 CPG authors in Japan, 21 (91.3%) received at least one payment, with the combined total of 4,081,629 during the same period. The 3-year combined average payment per author was 114,302) in Japan and 259,670) in US. 18 (78.3%) JDAPsACPG and 12 (48.0%) ACRPsACPG authors had undisclosed FCOI worth 218,501, respectively. The percentage of citations with at least one CPG author relative to total citations were 3.4% in Japan and 33.6% in US. 71.4% and 88.8% of recommendations for psoriatic arthritis in JDA and ACR were supported by low or very low quality of evidence.CONCLUSION: More rigorous cross-checking of information disclosed by pharmaceutical companies and self-reported by physicians, and more stringent and transparent COI policies are necessary.</p
Pharmaceutical payments to Japanese board-certified dermatologists: a 4-year retrospective analysis of personal payments from pharmaceutical companies between 2016 and 2019
Abstract There are prevalent financial relationships between dermatologists and pharmaceutical companies in Japan. However, little was known about the extent of whole picture of the personal payments made to dermatologists by pharmaceutical companies. This study aimed to examine the personal payments to the board-certified dermatologists by the Japanese Dermatological Association from the pharmaceutical companies between 2016 and 2019. Using the publicly disclosed payments data by the pharmaceutical companies between 2016 and 2019, we evaluated the magnitude, prevalence, and trends in the personal payments made to all board-certified dermatologists for the lecturing, writing, and consulting compensations. The payments were descriptively analyzed overall and by dermatologist demographics. Additionally, the payment trends were assessed by generalized estimating equation models. Of 6883 active board-certified dermatologists, 3121 (45.3%) received a total of 1737 (5287) and 4.0 (2.0–10.0) over the 4 years, respectively. Only top 1%, 5%, 10% of dermatologists received 41.7% (95% confidence interval [CI] 38.2–45.1%), 76.9% (95% CI 74.7–79.1%), and 87.6% (95% CI 86.2–88.9%) of overall payments. The number of dermatologists receiving payments and per-dermatologist payments increased by 4.3% (95% CI 3.1‒5.5%, p < 0.001) and 16.4% (95% CI 13.5‒19.4%, p < 0.001) each year. The board-certification in dermatology-oncology, in cosmetic dermatology, and male sex were significantly associated with higher personal payments with relative monetary values of 2.29 (95% CI 1.65–3.19, p < 0.001), 3.16 (95% CI 1.89–5.26, p < 0.001), and 5.38 (95% CI 4.12–7.04, p < 0.001). Less than half of Japanese board-certified dermatologists received lower personal payments from the pharmaceutical companies than those to other specialists. However, these personal payments were increasingly more prevalent and greater over the 4 years
Financial conflicts of interest in Japanese obstetrics and gynaecology clinical practice guidelines
Abstract This commentary analysis evaluated the size and prevalence of financial conflicts of interest among authors of Japanese obstetrics and gynaecology clinical practice guidelines. Our analysis found that 66% of all authors received personal payments totalling US$1.2 million during the guideline development period. Furthermore, the guideline chairpersons received much larger payments than those to other authors
Ubiquitin-like 3 as a new protein-sorting factor for small extracellular vesicles
Ubiquitin-like 3 (UBL3) is a well-conserved ubiquitin-like protein (UBL) in eukaryotes and regulates the ubiquitin cascade, but the significant roles of UBL3 in cellular processes remained unknown. Recently, UBL3 was elucidated to be a post-translational modification factor that promotes protein sorting to small extracellular vesicles (sEVs). Proteins sorted into sEVs have been studied as etiologies of sEV-related diseases. Also, there have been attempts to construct drug delivery systems (DDSs) by loading proteins into sEVs. In this review, we introduce the new concept that UBL3 has a critical role in the protein-sorting system and compare structure conservation between UBL3 and other UBLs from an evolutionary perspective. We conclude with future perspectives for the utility of UBL3 in sEV-related diseases and DDS. Key words: UBL3, small extracellular vesicles, protein sorting, ubiquitin-like protein, post-translational modificatio
