INTRODUCTION: Little is known about the impact of gender-affirming hormone therapy (GAHT) on transgender and gender diverse adults with inflammatory bowel disease (IBD). The primary aim was to evaluate the incidence of IBD flare in the year before and after GAHT initiation. METHODS: A retrospective study across 5 IBD centers. Flare was defined as need for steroids, IBD-associated emergency department visit, or need for IBD medication change. Factors associated with IBD flare were assessed with univariate analysis and multivariable logistic regression controlling for age and IBD type. RESULTS: A total of 85 transgender and gender diverse adults with IBD who initiated GAHT were included in this study. Forty-six (54.1%) received estrogen and 39 (45.9%) received testosterone. In the year before GAHT, 42 (49%) flared compared with 32 (38%) in the year after, P = 0.06. There was no statistically significant difference in incidence of flare by age, IBD type, or IBD therapy type. Individuals with active IBD at GAHT initiation were more likely to flare in univariate (58% vs 24%, P = 0.003) and multivariable analyses (adjusted odds ratio 5.1, 95% confidence interval 1.7–15.2). In both univariate and multivariable analyses, individuals who received testosterone were more likely to flare in the year after starting GAHT, testosterone: 51% vs estrogen: 26%, P = 0.02 with an adjusted odds ratio 3.1 (95% confidence interval 1.2–8.1). DISCUSSION: Although there was no overall increased risk of flare in the year after GAHT start, those with active IBD before hormone start and those who received testosterone were more likely to experience an IBD flare.

Background Olfactory dysfunction (OD) is a common symptom in patients with coronavirus disease 2019 (COVID-19) with limited treatment options. Objective This pilot study aimed to investigate an acupuncture protocol in patients with COVID-19 related OD. Methods Thirty patients were randomized into 2 groups. The standard group was treated with budesonide nasal irrigation and olfactory training. The acupuncture group received ten sessions of acupuncture therapy in addition to the standard group treatment. Olfaction was assessed using the University of Pennsylvania Smell Identification Test, 10-point visual analog scale, and Sino-Nasal Outcome Test at baseline and after 3 months of treatment. Differences between study arms were compared using Fisher’s exact and Wilcoxon rank sum tests. Results Eighteen of the 30 (60%) enrolled patients completed the study, including 11 (73%) in the standard and 7 (47%) in the acupuncture group. Reasons for participant drop-out included cost of travel and time constraints. There were no acupuncture complications. Conclusions Acupuncture as an adjunct therapy for COVID-19 related OD is well tolerated. Subsequent studies with larger sample sizes are needed to assess the effect of acupuncture on OD.

Objective To develop and validate classification criteria for pediatric chronic nonbacterial osteomyelitis (CNO) jointly supported by EULAR and the American College of Rheumatology (ACR). Methods This international initiative had 4 phases: (1) candidate items were proposed in a survey of pediatric rheumatologists, (2) criteria definition and reduction by Delphi and nominal group technique exercises, (3) criteria weighting using multicriteria decision analysis, and (4) refinement of weights and threshold score in a development cohort of 441 patients and validation in another cohort of 514 patients. Results The new EULAR/ACR classification criteria for CNO require typical radiographic or magnetic resonance imaging findings and bone pain as an obligatory entry criterion and exclusion criteria of malignancy, infection, vitamin C deficiency, and hypophosphatasia, followed by additive weighted criteria in 5 clinical (site of bone lesions, pattern of bone lesions, age at onset, coexisting conditions, fever) and 4 pathology/laboratory domains (bone biopsy findings if done, anemia, C‐reactive protein level, and erythrocyte sedimentation rate). A total score ≥55 is required for classification as CNO. The new criteria had a sensitivity of 82% and specificity of 98% in the validation cohort. Conclusion These new classification criteria for pediatric CNO developed with international input reflect current views about CNO, have high specificity and good sensitivity, and provide a key foundation for future CNO research.

ABSTRACT Cellular senescence is a stress response mechanism marked by irreversible growth arrest, upregulation of antiapoptotic pathways, loss of cellular function, and remodelling of the cellular secretory profile. In both humans and mice, pancreatic β-cells undergo senescence with age and insulin resistance. Targeted removal of senescent cells in mouse models of diabetes improves glucose homeostasis, demonstrating the role β-cell senescence in diabetes progression. In contrast, β-cell senescence also promotes immune surveillance, promoting β-cell survival and function. Thus, a better understanding of senescent cells’ phenotypic and functional heterogeneity is needed to develop effective therapeutic strategies. Herein, we show that subpopulations of senescent β-cells in mice and humans, which were identified through the expression of Cdkn1a (encoding p21 Cip1 ) and Cdkn2a (encoding p16 Ink4a ) by single-cell RNA sequencing (scRNA-seq), flow cytometry, spatial transcriptomics, and spatial proteomics, exhibit distinct transcriptional and functional identities. The predominant senescent β-cell subpopulation expressed Cdkn1a and was characterized by a lack of glucose responsiveness, high basal insulin secretion, and transcription of canonical SASP factors. The SASP of Cdkn1a -expressing β-cells had non-cell autonomous effects on neighbouring cells. A subset of four SASP factors from Cdkn1a + cells was sufficient to induce secondary senescence and β-cell dysfunction in vitro . JAK inhibitors (JAK1/2 and JAK1/3) counteracted secondary senescence induction and restored β-cell function in high-fat diet-fed mice and human islets from donors with or without type 2 diabetes.

Objective We aimed to assess the occurrence of carpal tunnel syndrome (CTS) before and after rheumatoid arthritis (RA) incidence and by serologic status. Methods This population‐based study included residents of a geographically defined area meeting the 1987 American College of Rheumatology classification criteria for RA in 1980 to 2019 matched 1:1 with individuals without RA. At least two diagnosis codes ≥30 days apart were used to identify CTS. Cumulative incidence of CTS adjusting for competing risk of death was assessed. Logistic regression and Cox proportional hazard models were used, adjusting for age, sex, calendar year, smoking, obesity, diabetes mellitus, and hypothyroidism. Results We included 1,335 patients with RA and 1,331 individuals without RA. The overall prevalence of CTS before or on RA incidence or index was 179 patients with RA (13%) and 85 individuals without RA (6%), respectively (odds ratio [OR] 2.23; 95% confidence interval [CI] 1.69–2.94). Most previous incidences of CTS occurred ≥2 years before the index date (112 events in patients with RA and 75 events in individuals without RA, respectively). Following RA incidence or index, individuals with RA (vs those without RA) had ~80%‐higher risk of CTS (hazard ratio [HR] 1.78; 95% CI 1.38–2.30). The risk estimates of CTS in patients with seronegative (vs seropositive) RA were OR 1.33 (95% CI 0.96–1.84) before RA incidence and HR 1.37 (95% CI 0.99–1.88) after RA incidence. In RA, obesity (HR 1.42, 95% CI 1.02–1.99) and seronegative cyclic citrullinated peptide antibody status (HR 1.79, 95% CI 1.07–2.99), but not other risk factors, were associated with increased CTS risk. Conclusion We found a more than two‐fold increase in risk of CTS in the years preceding RA and a 1.8‐fold increased risk of incident CTS following RA onset. image

Abstract Objective Glucocorticoid withdrawal syndrome (GWS) may develop in patients following successful surgery for endogenous hypercortisolism. Effective strategies to minimize GWS and improve quality of life (QoL) are currently lacking. We aimed to determine the impact of hydrocortisone vs prednisone therapy on GWS and QoL during the first 12 weeks postsurgery. Methods Single-center prospective cohort study (2019-2024) of adults with endogenous hypercortisolism who developed postoperative adrenal insufficiency and treated with either prednisone or hydrocortisone. Quality of life was assessed with Short Form-36 (SF-36) and Cushing QoL questionnaires at baseline and at 12 weeks postsurgery. GWS was assessed using weekly AddiQoL questionnaires for the first 12 weeks postsurgery. Results Of 165 patients, 101 (61%) were treated with hydrocortisone and 64 (39%) with prednisone. At baseline, no group differences were found in the hypercortisolism subtype, comorbidities, or QoL assessments. At follow-up, no group differences in final total daily hydrocortisone equivalent dose were seen. When adjusting for the baseline QoL assessment, patients treated with prednisone demonstrated a higher degree of improvement in their QoL, particularly in the SF-36 mental component score (estimate 0.33, 95% CI, 0.04-0.63), SF-36 role-emotional limitation (estimate 0.52, 95% CI, 0.2-0.84), and SF-36 body pain (estimate 0.31, 95% CI, 0.07-0.56) subcomponents. In the multivariable analysis of age, sex, body mass index, glucocorticoid type, baseline clinical severity score, and baseline QoL assessment, prednisone therapy was an independent predictor of better SF-36 mental component at 12 weeks postsurgery. Conclusions Prednisone therapy was associated with better mental health QoL than hydrocortisone at 12 weeks postsurgery in patients with hypercortisolism.
