Vitamin D deficiency is frequently reported in hidradenitis suppurativa (HS), but its clinical significance remains unclear. In a retrospective cohort of 503 patients, deficiency was common and associated with demographic and metabolic factors but not with treatment-defined severity. Vitamin D deficiency was independently associated with elevated C-reactive protein, suggesting a link with systemic inflammation.

Background: Given the faster onset and shorter duration of action of ultra-rapid insulin lispro-aabc (URLi, Lyumjev™ insulin), compared with insulin lispro (a rapid-acting insulin [RAI]), the present study investigated the safety and glycemic outcomes of MiniMed™ 780G advanced hybrid closed-loop (AHCL) use with URLi in youths and adults with T1D. Methods: This 19-site, single-arm, clinical trial enrolled children and adolescents (aged 7–17 years) and adults (aged 18–80 years) with T1D who underwent a run-in period (∼2 weeks) using open loop or automated basal only with an RAI (aspart or lispro), followed by a 3-month study period using URLi with AHCL (AHCL + URLi). End-of-study glycemic metrics and A1c were compared to predefined thresholds and to data from baseline/run-in. Use of recommended optimal settings (ROS, 100 mg/dL glucose target with an active insulin time [AIT] of 2 h) was also assessed. Results: In an intention-to-treat population ( N = 101 pediatric and N = 110 adult participants), percentage of time in range (%TIR) during the last ∼6 weeks of the study period was significantly greater than the predefined thresholds for both the pediatric and adult participants. A1c was unchanged in the pediatric cohort but significantly reduced in the adult cohort (from 7.4 ± 0.9% to 6.9 ± 0.6% [ P < 0.001]). Compared with run-in, study period %TIR and percentage of time in tight target range (%TITR) were significantly increased (pediatric mean %TIRΔ [17.4%] and %TITRΔ [16.0%], respectively, and adult mean %TIRΔ [10.6%] and %TITRΔ [11.6%], respectively; P < 0.001 for all). Additionally, % time above range for both groups was significantly reduced. Use of ROS allowed more participants to achieve recommended glycemic targets. There were no severe hypoglycemia or diabetic ketoacidosis events. Most caregivers agreed that mealtime versus premeal URLi delivery simplified pediatric meal management. Conclusions: Similar to previous studies investigating automated URLi delivery, URLi use in the MiniMed™ 780G system was safe, and glycemic outcomes were favorable for pediatric and adult participants.

Abstract Importance Decline in olfactory function may be used as a predictor of cognitive decline, to enhance early detection models, improve risk stratification, and enable early intervention. Objective To assess the longitudinal association between olfactory decline, cognitive decline, and postmortem neuropathology. Design, setting and participants Retrospective longitudinal analysis with clinicopathological correlations of a prospective population-based cohort study using data from the Arizona Study of Aging and Neurodegenerative Disorders (AZSAND) and its Brain and Body Donation Program. Participants included cognitively unimpaired individuals without parkinsonism that converted to mild cognitive impairment (MCI) and/or dementia or remained cognitively stable. Main Outcomes and Measures longitudinal change in olfaction, neuropsychiatric symptoms, motor function and memory, conversion to MCI/dementia, postmortem neuropathology Results Over a mean follow-up period of 7.7 ± 5.4 years, out of 922 participants who were cognitively unimpaired at the first cognitive conference, 643 remained cognitively unimpaired, 279 converted to MCI, and 82 developed dementia. Of these, 633 individuals had at least 2 olfactory tests. Converters showed reduced olfactory function (t=-12.6, p <0.0001), faster progression in neuropsychiatric symptom burden (t=3.42, p < 0.001), and faster decline in memory (t= -7.33, p <0.0001) prior to conversion while no significant differences were observed in motor scores between converters and non-converters. Using ROC analysis, olfactory decline, increased neuropsychiatric symptom burden, as well as motor and memory decline predicted conversion to MCI with a consistent accuracy of ∼ 70% up to 5 years before conversion, while UPSIT alone had an accuracy of ∼ 60%. Longitudinal decline in olfaction was associated with a higher burden of a-synuclein (t= -8.21, p <0.0005), tau tangle (t= -2.66, p < 0.01) and amyloid plaque burden (t= -2.85, p < 0.005) and a faster decline over time was associated with a higher burden of tau (t=5.66, p<0.0001). Conclusions and Relevance A reduction in olfactory identification ability is observed up to a decade prior to conversion to MCI and is associated with underlying burden of neuropathology markers, underscoring the value of incorporating olfactory testing in cognitively unimpaired individuals to identify those at-risk of future cognitive decline.

Multi-listing (ML) increases the odds of transplantation compared with single-center listing. However, not all patients have equivalent access to ML. The recent allocation policy change prioritized distance from the donor hospital in an attempt to decrease geographic disparities. This study assessed access to liver transplant (LT) given ML practices before and after the acuity circles policy change. United Network for Organ Sharing data were queried for LTs between January 1, 2016, and November 1, 2024. Patients were grouped by listing at one versus multiple centers and by acuity circle era (ACE). Cohort characteristics and comparisons were described using chi-square and Wilcoxon rank tests. Multivariable logistic regressions and propensity score match (PSM) were performed to assess associations between ML and LT. The final cohort consisted of 105,030 patients; 4084 (3.9%) were multi-listed. Racial/ethnic minority groups, less educated, and publicly insured candidates were less often multi-listed. ML was positively associated with LT in all analyses (overall: OR=1.180, p <0.001; PSM: OR=1.164, p =0.001; pre-ACE: OR=1.127, p =0.015; post-ACE: OR=1.218, p <0.001). Education, race/ethnicity, and insurance type were also associated with LT across all analyses. ML patients were more often transplanted at their primary center with a significant increase in primary center LT post-ACE (53.4% vs. 63.4%, p <0.001). ML and LT had a positive correlation. There was a negative association between minority groups and ML as well as LT. Although acuity circles decreased geographic disparities, they did not change ML accessibility across candidates.

Abstract Cutaneous IgM/IgG immune complex vasculitis is a newly recognized provisional subtype of single-organ vasculitis that is clinically indistinguishable from IgA vasculitis. This retrospective case series evaluated the presence, clinicopathological characteristics and outcomes of patients with IgM and/or IgG dominance or codominance on direct immunofluorescence testing (2010–23). This review represents only the second study to date to characterize this population. Early analysis of 14 patients revealed that cutaneous IgM/IgG immune complex vasculitis was mainly skin limited, and treatment with topical and oral corticosteroids typically resulted in complete resolution without recurrence. Additionally, this study demonstrated that nearly two-thirds (64%) of patients with cutaneous small-vessel vasculitis with IgM and/or IgG dominance or codominance on direct immunofluorescence were ultimately found to have an underlying autoimmune connective tissue disease, cryoglobulinaemia, antineutrophil cytoplasmic antibody-associated vasculitis, infection or a drug-related cause. Therefore, it is imperative that clinicians perform a thorough investigation of this unique population to evaluate for potential underlying diseases and/or triggers.

Abstract Background/Aims Sleep disturbance is a defining feature of fibromyalgia (FM), contributing to pain, fatigue, cognitive dysfunction, and reduced quality of life. Effective management options remain limited. Cognitive behavioural therapy for insomnia (CBT-I) is effective in primary insomnia, but evidence in FM is sparse and access to face-to-face therapy is limited. Digital CBT-I (dCBT-I) offers a scalable, self-directed solution that may overcome these barriers. We conducted the first randomised controlled trial of dCBT-I in FM to evaluate its impact on quality of life and associated symptoms. Methods This single-blind randomised controlled trial evaluated Sleepio, a validated dCBT-I programme of six self-directed 20-minute sessions delivered over 12 weeks. Participants with a clinical diagnosis of FM, self-reported sleep disturbance, and cognitive complaints were recruited in Oxford, UK. After baseline assessment, participants were randomized to dCBT-I or a control group. All participants also received standardised sleep hygiene advice. The primary outcome was disease-specific quality of life measured by the revised Fibromyalgia Impact Questionnaire (FIQR). Secondary outcomes included insomnia severity (Insomnia Severity Index), actigraphy-derived sleep parameters, pain (SF36 Bodily Pain Scale), cognitive complaints (British Columbia Cognitive Complaints Inventory), sustained attention, and fear of movement (Tampa Scale of Kinesiophobia). Outcomes were collected online at baseline, 3 months, and 6 months. Analyses followed the intention-to-treat principle using constrained longitudinal data analysis. Ethical approval was obtained from South Central - Oxford B Research Ethics Committee (19/SC/0168). The study was pre-registered with clinicaltrials.gov (NCT05962138). Results Of 514 individuals contacted, 241 were screened, 132 were eligible, and 80 were randomised (42 dCBT-I, 38 control). The mean age was 46.6 (SD 14.5) years; 93.8% were female. Retention was high: 97.5% of participants provided outcomes at 3 months, and 83.8% at 6 months. In the dCBT-I group, 90.5% initiated the programme, and 54.8% reached the core session on sleep restriction therapy. At 3 months, there was no significant difference between groups in FIQR (mean difference −2.79; p = 0.3). At 6 months, however, dCBT-I participants demonstrated greater improvement in FIQR compared with controls (mean difference −5.45; 95% CI − 10.5 to − 0.4; p = 0.035), corresponding to a small-to-moderate effect size (Cohen’s d = −0.31). No significant between-group differences were observed for secondary outcomes. Conclusion In adults with FM, dCBT-I produced a sustained, clinically meaningful improvement in disease-related quality of life at 6 months compared with a sleep hygiene control. Although benefits were not observed across secondary outcomes, this trial provides the first controlled evidence that dCBT-I can address an important unmet need in FM. Digital behavioural therapies represent scalable, accessible, non-pharmacological interventions with potential for rapid integration into clinical care. Disclosure E.

We report correlative circulating tumor DNA (ctDNA) analyses from TRANSFORM (ClinicalTrials.gov identifier: NCT03575351 ) evaluating lisocabtagene maraleucel (liso-cel) versus standard of care (salvage immunochemotherapy, high-dose chemotherapy, autologous stem cell transplantation [ASCT]) in second-line large B-cell lymphoma (LBCL). ctDNA association with efficacy was investigated at predefined time points (random assignment, day 43, day 64, and day 126 [3 months after liso-cel, approximately 2 months after ASCT]) for 136 patients using ultrasensitive PhasED-Seq. ctDNA clearance (measurable residual disease [MRD] neg ) predicted longer event-free survival (EFS) at all time points in both arms, with significantly more liso-cel–treated patients achieving MRD neg . Liso-cel demonstrated superior outcomes versus ASCT, including longer EFS, progression-free survival (PFS), and duration of response among patients in complete response (CR) and MRD neg . ctDNA re-emergence in patients with CR after ASCT confirmed its potential in predicting relapse. MRD neg remained significantly associated with EFS after adjusting for positron emission tomography (PET) response, while interaction testing revealed a significant interaction between PET status and treatment arm for EFS. Liso-cel achieved deeper, more durable molecular clearance by ctDNA, consistent with superior EFS and PFS versus ASCT for second-line LBCL treatment. ctDNA-MRD provided prognostic value beyond PET, supporting its role as a complementary biomarker for treatment response and relapse prediction.
