Objective: To compare the effectiveness of JAK inhibitors (JAKis) and biologic disease-modifying antirheumatic drugs (bDMARDs) on pain in patients with rheumatoid arthritis.

Methods: In this retrospective study, we investigated patients with a diagnosis of rheumatoid arthritis, starting treatment with a JAKi (n = 1,827), a tumor necrosis factor inhibitor (TNFi; n = 6,422), an interleukin-6 inhibitor (n = 887), abatacept (n = 1,102), or rituximab (n = 1,149) in 2017 to 2019, using data from several linked Swedish national registers. Differences in change in pain, assessed with a visual analogue scale (0-100 mm), from baseline to 3 months, as well as proportions of patients remaining on initial treatment with low pain (visual analogue scale pain <20) at 12 months, were compared between treatments.

Article Synopsis
  • The study aimed to explore sex differences in patient-reported outcomes (PROMs) among patients with axial spondyloarthritis (axSpA) starting their first tumor necrosis factor inhibitor (TNFi).
  • Data from 15 registries were analyzed, focusing on changes in BASDAI and BASFI scores over 24 months using linear mixed models.
  • Results indicated that women reported significantly worse outcomes than men, with the sex differences in scores nearly doubling after 6 months, and baseline characteristics such as HLA-B27 positivity and disease duration helped explain some but not all of the differences.

Objective: While considerable focus has been placed on pain due to inflammation in psoriatic arthritis (PsA), less is reported on pain despite inflammation control. Here, we aimed to investigate the occurrence/predictors of persistent pain, including non-inflammatory components, after starting anti-tumour necrosis factor (anti-TNF) therapy.

Method: Bionaïve PsA patients starting a first anti-TNF therapy 2004-2010 were identified (South Swedish Arthritis Treatment Group register; N = 351).

Article Synopsis
  • The study aims to assess the cost-effectiveness of bimekizumab, an IL-17A and IL-17F inhibitor, compared to other biologic drugs for treating psoriatic arthritis in Sweden, using a Markov model over a lifetime.
  • Results show that bimekizumab offers higher quality-adjusted life years (QALYs) than most comparators, particularly for patients naive to biologics, while being cost-effective against various other treatment options.
  • Limitations include reliance on network meta-analysis for effectiveness data and gaps in evidence regarding disease management and indirect costs related to Health Assessment Questionnaire-Disability Index scores.

Introduction: We aimed to compare the proportions of patients with newly diagnosed psoriatic arthritis (PsA) and rheumatoid arthritis (RA) remaining on methotrexate (regardless of other disease-modifying antirheumatic drug (DMARD)-changes), and proportions not having started another DMARD (regardless of methotrexate discontinuation), within 2 years of starting methotrexate, as well as methotrexate effectiveness.

Methods: Patients with DMARD-naïve, newly diagnosed PsA, starting methotrexate 2011-2019, were identified from high-quality national Swedish registers and matched 1:1 to comparable patients with RA. Proportions remaining on methotrexate and not starting another DMARD were calculated.

Thermal comfort during sleep is essential for both sleep quality and human health while sleeping. There are currently few effective contactless methods for detecting the sleep thermal comfort at any time of day or night. In this paper, a vision-based detection approach for human thermal comfort while sleeping was proposed, which is intended to avoid overcooling/overheating supply, meet the thermal comfort needs of human sleep, and improve human sleep quality and health.

The honeybee gut microbiome is thought to be important for bee health, but the role of the individual members is poorly understood. Here, we present closed genomes and associated mobilomes of 102 Apilactobacillus kunkeei isolates obtained from the honey crop (foregut) of honeybees sampled from beehives in Helsingborg in the south of Sweden and from the islands Gotland and Ã…land in the Baltic Sea. Each beehive contained a unique composition of isolates and repeated sampling of similar isolates from two beehives in Helsingborg suggests that the bacterial community is stably maintained across bee generations during the summer months.

Several suggestions have been made as to why Sweden's approach to managing the COVID-19 pandemic came to rely on a strategy based on voluntary measures. Two of the most prominent explanations for why the country chose a different strategy than many other countries have focused on micro- and macro-level factors, explaining the strategy either in terms of the psychologies of prominent actors or by pointing to particularities in Swedish constitutional law. Supported by a qualitative analysis using interviews and text analysis, we argue that the Swedish strategy cannot be understood without paying attention to the meso-level and the organizations that produced the strategy.
