- PURPOSE: (i) To report the prevalence of participants to a first-line intervention for OA in Sweden using over-the-counter (OTC) and/or prescribed NSAIDs; (ii) To estimate the accuracy of dispensed prescriptions of NSAIDs recorded in a Swedish health-care register to capture the use of NSAID considering clinician-report as reference standard.METHODS: Register-based study. We used data from OA individuals who participated in the Swedish first-line intervention recorded in the Swedish Osteoarthritis Register (SOAR). SOAR includes clinician-reported use of NSAIDs in the three months preceding the intervention. We used the Prescribed Drug Register to retrieve data on NSAID prescriptions dispensed in the same period. We estimated the prevalence of OTC users (individuals with clinicians-reported use of NSAID but no prescription dispensed), prescription users (individuals with clinicians-reported use of NSAID and a prescription dispensed) and non-users (neither of the previous). We calculated sensitivity, specificity, positive predictive value, and negative predictive value of dispensed prescriptions of NSAIDs vs clinician-report.RESULTS: We included 116,162 individuals (mean age [Standard Deviation]: 66 [9.6] years, 79% women, 77% knee OA). Overall, 24.7% (95% Confidence Intervals [CI] 24.5%; 25.0%) used OTC NSAIDs only, 18.2% (18.0%; 18.5%) used prescribed NSAIDs, 6.6% (6-4%; 6.7%) reported not using NSAIDs while having an NSAID prescription dispensed. Of the 49,913 individuals with clinician-reported use of NSAIDs, 21,190 had a prescription dispensed (sensitivity: 42.5% [95% CI 42.0%, 42.9%]; positive predictive value: 73.5% [73.0%, 74.0%]). Of the 66,249 individuals reporting not using NSAIDs, 58,617 did not have a prescription dispensed (specificity: 88.5% [88.2%, 88.7%]; negative predictive value: 67.1% [66.8%, 67.4%]).CONCLUSION: Overall, 24.7% of participants in a first-line intervention for OA used OTC NSAIDs only while 18.2% used prescribed NSAIDs. Dispensed prescriptions of NSAIDs have high specificity but low sensitivity and can correctly identify about 70% of both the non-users and users in this population.

- OBJECTIVE: To compare the prevalence and timing of knee surgery (including meniscal, ligamentous, synovial, and osteotomy) in the 10 years prior to primary total knee replacement (TKR) between England and Sweden.METHODS: This was a population-based, case-control study within England and southern Sweden using electronic health care databases. Patients underwent primary TKR between 2015 and 2019. Risk-set sampling showed that general population controls matched 1:1 by age, sex, and practice/municipality. The annual prevalence and prevalence ratio of having at least 1 recorded surgery in each of the 10 years preceding TKR was estimated using Poisson regressions.RESULTS: We included 6,308 and 47,010 TKR cases in Sweden and England, respectively. Meniscal surgeries were the most frequent procedure prior to TKR in both countries; prevalence was higher in England across all time points. The prevalence of meniscal surgery increased in both countries in the years approaching TKR, reaching 33.2 (95% confidence interval [95% CI] 31.6-34.9) per 1,000 persons in England, and 9.83 (95% CI 7.66-12.61) in Sweden. In England, we observed a decrease from 2014 to 2018 in the utilization of this procedure in the 4 years preceding a TKR. The prevalence of all analyzed surgeries was consistently lower in controls.CONCLUSION: There are comparable trends in the use of knee surgery in the years preceding TKR across England and Sweden. Of note, meniscal surgeries remain common, even within the year prior to TKR, highlighting that these patients may experience low-value care. Careful consideration of knee surgery in those with late-stage disease is required.

- Aim To investigate temporal trends in primary care visits, physiotherapy visits, dispensed non-steroidal anti-inflammatory drugs (NSAIDs) and opioids in knee osteoarthritis (OA) patients who have and have not undergone knee replacement. Methods We analysed 5665 OA patients from the Skåne Healthcare Register, Sweden, who underwent knee replacement between 2015 and 2019. Controls were OA patients without knee replacement, matched 1:1 by sex, age, time and healthcare level of initial OA diagnosis, and assigned a pseudo-index date corresponding to their case's knee replacement date. Annual prevalence and prevalence ratio of primary care and physiotherapy visits, dispensed NSAIDs and opioids (all for any cause) in the 10 years before knee replacement were estimated using Poisson regression. Results The annual prevalence of all-cause primary care visits, physiotherapy visits and opioid use was similar between cases and controls until 3 years before the index date when it started to increase among the cases. The year before the index date, the prevalence ratio (cases vs controls) for physiotherapy use was 1.8 (95% CI 1.7, 1.8), while for opioid use 1.6 (1.5, 1.7). NSAID use was consistently higher among cases, even 10 years before the index date when the prevalence ratio versus controls was 1.3 (1.2, 1.3), increasing to 1.8 (1.7, 1.9) in the year preceding the index date. Conclusions Management of OA patients who have and have not undergone knee replacement appears largely similar except for higher use of NSAIDs in knee replacement cases. Symptomatic treatments start to increase a few years before the surgery in knee replacement cases.

- BACKGROUND: A recently published East Asian genome-wide association study of Parkinson;s disease (PD) reported 2 novel risk loci, SV2C and WBSCR17.OBJECTIVES: The objective of this study were to determine whether recently reported novel SV2C and WBSCR17 loci contribute to the risk of developing PD in European and East Asian ancestry populations.METHODS: We report an association analysis of recently reported variants with PD in the COURAGE-PD cohort (9673 PD patients; 8465 controls) comprising individuals of European and East Asian ancestries. In addition, publicly available summary data (41,386 PD patients; 476,428 controls) were pooled.RESULTS: Our findings confirmed the role of the SV2C variant in PD pathogenesis (rs246814, COURAGE-PD PEuropean = 6.64 × 10-4 , pooled PD P = 1.15 × 10-11 ). The WBSCR17 rs9638616 was observed as a significant risk marker in the East Asian pooled population only (P = 1.16 × 10-8 ).CONCLUSIONS: Our comprehensive study provides an up-to-date summary of recently detected novel loci in different PD populations and confirmed the role of SV2C locus as a novel risk factor for PD irrespective of the population or ethnic group analyzed. © 2021 The Authors.

- Objective: To determine the nationwide prevalence of primary dystonia, ataxia and hereditary spastic paraplegia (HSP) in Sweden. Methods: We extracted data on all patients who were registered in The National Patient Register (NPR) in Sweden (population 9.64 million) at least twice during five consecutive years with a diagnosis of primary dystonia, ataxia or HSP. We excluded patients with an additional diagnosis possibly indicating secondary causes, and determined the proportion of wrongly diagnosed patients at our own tertiary center by patient examination or chart review. We analyzed patients' age and disorder subtypes, geographical distribution of patients within Sweden and the country of birth of all patients. Results: Nationwide, we identified 4239 patients (31.6% male) with a diagnosis of primary dystonia. Of 347 patients with dystonia at our center, 20.2% may have had a different final diagnosis. Extrapolation of this uncertainty rate to the national population resulted in a prevalence for primary dystonia of 35.1/100,000. There were 672 patients (49.6% male) with ataxia in NPR, and the diagnostic uncertainty rate among 81 patients in our center was 13.6% (prevalence 6.0/100,000). HSP was diagnosed in 235 patients nationwide (52.3% male, prevalence 2.4/100,000). Patients were distributed relatively evenly throughout the country. The proportions of patients with these diagnoses who were born outside of Sweden were lower (8.0-12.7%) than the proportion of all Swedish residents born abroad (15.9%). Conclusions: In this large, nationwide study, the prevalence of dystonia was high compared to previous studies, which partly may be explained by the high coverage of NPR.
