Purpose: To evaluate two-year mortality predictors in all subtypes of fragility fractures.

Methods: Medical records review, single-center study with Portuguese patients with fragility fractures; A univariate analysis, with chi-square for categorical variables and parametric t-student and non-parametric Wilcoxon tests for continuous variables, was performed. Posteriorly, a survival analysis, with subsequent Cox regression was conducted to establish independent risk factors/ predictors of two-year mortality in fragility fractures.

Results: 758 patients were enrolled in the study. We found a total of 151 deaths within the first two years post-fracture. On Cox regression, older age [OR1.10 CI (1.05-1.11)], male sex [OR1.85 CI(1.24-2.75)], anemia at baseline [OR2.44 CI(1.67-3.57)], malignancy [OR4.68 CI (2.13-10.27)], and multimorbidity [OR1.78 CI(1.11-2.87)] were found as independent predictors for two-year post-fracture mortality.

Conclusion: Our study suggests that male sex, older age, anemia, malignancy, and multimorbidity are mortality predictors in the first two years after fragility fractures, reinforcing the importance of comorbidity management in preventing or, at least, minimizing adverse outcomes following fragility fractures.

Objectives: To describe a Romanian cohort of patients with juvenile dermatomyositis (JDM) and to identify factors associated with disease severity, complete clinical response, and sustained remission.

Methods: We retrospectively reviewed data from 30 JDM patients from 2013 to 2022. The inactive disease state was defined as no active skin rash, muscle weakness, or elevated muscle enzymes. A complete clinical response implied a status of inactive disease maintained for six consecutive months while on medication and remission of inactive disease for at least six consecutive months after treatment. Association factors and predictors of time to complete clinical response and time to remission emerged from bivariate correlation (Pearson's coefficient) and univariate survival analysis (Kaplan-Meier analysis).

Results: The median times to complete clinical response and time to remission for the entire cohort were 30.5 months (2.5 years) and 48.5 months (4.04 years), respectively. Nine patients (30%) had a severe disease course, while twenty-one patients (70%) had a mild/moderate course. The presence of calcinosis, time to corticosteroid discontinuation, history of treatment escalation in the first 18 months, and treatment with azathioprine or biologic DMARDs were strongly associated with a longer time to clinical remission (Pearson's > 0.5, p < 0.05). Seven patients (23%) achieved remission, and none of them relapsed during the subsequent median follow-up of 19 months.

Objectives: Vascular ultrasound is commonly used to diagnose giant cell arteritis (GCA). Most protocols include the temporal arteries and axillary arteries, but it is unclear which other arteries should be included. This study investigated whether inclusion of intima media thickness (IMT) of the common carotid artery (CCA) in the ultrasound evaluation of GCA improves the accuracy of the examination.

Methods: We formed a fast-track clinic to use ultrasound to rapidly evaluate patients with suspected GCA. In this cohort study, patients referred for new concern for GCA received a vascular ultrasound for GCA with the temporal arteries and branches, the axillary artery, and CCA.

Results: We compared 57 patients with GCA and 86 patients without GCA. Three patients with GCA had isolated positive CCA between 1 and 1.49 mm, and 21 patients without GCA had isolated positive CCA IMT. At the 1.5-mm CCA cutoff, 4 patients without GCA had positive isolated CCA, and 1 patient with GCA had a positive isolated CCA. The sensitivity of ultrasound when adding carotid arteries to temporal and axillary arteries was 84.21% and specificity 65.12% at an intima media thickness (IMT) cutoff of ≥1 mm and 80.70% and 87.21%, respectively, at a cutoff of ≥1.5 mm.

Conclusion: Measurement of the CCA IMT rarely contributed to the diagnosis of GCA and increased the rate of false-positive results. Our data suggest that the CCA should be excluded in the initial vascular artery ultrasound protocol for diagnosing GCA. If included, an IMT cutoff of higher than 1.0 mm should be used.

Background and objectives: Renal involvement in systemic sclerosis remains a significant concern with the focus often centered on scleroderma renal crisis (SRC). However, the broader spectrum of renal manifestations, beyond SRC, remains underrecognized. In our case-control analysis, we describe other causes, risk factors, and renal outcomes of acute kidney injury (AKI) in systemic sclerosis other than SRC.

Methods: Patients diagnosed with SSC, with and without AKI, between 2017 and 2023 at Albany Medical Center, were included in the case-control study using International Classification of Diseases , 10th Revision codes and electronic medical records. Patients with SRC were carefully excluded. Data were collected and compared between AKI and non-AKI groups for patients' demographics, clinical characteristics, and baseline treatment. Additionally, data were collected for baseline, peak, and follow-up creatinine, etiology of AKI, treatment, and outcomes. Statistical analysis was performed using R (version 4.3.0) and Minitab (V19). Categorical variables were presented as frequencies/percentages, and continuous variables as means/standard deviations. Associations between categorical variables were assessed by χ 2 test and Fisher exact test. Odds ratios and 95% confidence intervals were calculated using binary logistic regression to separately assess the effect of each independent variable on the odds of AKI. Statistical significance was set at p < 0.05.

Results: A total of 74 cases were identified. Out of these 74 cases, 27 had AKI and 47 did not have AKI. Out of the 27 AKI cases, 4 with SRC were excluded. Advanced age, chronic kidney disease, and heart failure were identified as risk factors for AKI development. The predominant cause of AKI was prerenal etiology, accounting for 47.8% (n = 11) of cases. This was followed by cardiorenal syndrome and acute tubular necrosis, accounting for 21.7% and 17.3% of the cases, respectively. Most of the cases with AKI had complete renal recovery 78% (n = 18), whereas 17% (n = 4) had progression of the underlying chronic kidney disease. One patient progressed to end-stage renal disease requiring hemodialysis.

Conclusions: This analysis highlights the risk factors and variable clinicopathological courses of renal involvement in patients with scleroderma. This may range from mild AKI with good prognosis to life-threatening SRC.

Objective: The exact effects of MEFV variants on inflammation are still under investigation, and reports on variants of unknown significance, particularly the E148Q variant, have been conflicting. Therefore, this study aims to investigate patients exhibiting E148Q heterozygosity, focusing on diagnoses and disease courses to assist physicians in interpreting the variant.

Methods: Data of pediatric patients presenting to the Pediatric Rheumatology clinic between November 2016 and September 2023, exhibiting only E148Q heterozygosity in MEFV gene analysis, were extracted. Patients who were lost before 9 months of follow-up have been excluded to ensure the completion of initial diagnostic tests and evaluations.

Results: Among the 119 patients with E148Q variant, the diagnoses were as follows: healthy, 51.3%; IgA vasculitis, 10.1%; Familial Mediterranean Fever (FMF), 7.6%; Periodic fever, Aphtous stomatitis, Pharyngitis, Adenitis (PFAPA), 6.7%; and other diagnoses, 19.3%. IgA vasculitis patients experienced articular, gastrointestinal, and renal involvement at rates of 91.7%, 58.3%, and 16.7%, respectively. Complete response, partial response, and no response to colchicine were 37.5%, 12.5%, and 50%, respectively, in PFAPA patients. All FMF patients responded to colchicine treatment resulting in reduced mean FMF episode counts in 6 months from 3.22 ± 0.92 to 0.56 ± 0.52.

Conclusions: The E148Q variant may amplify inflammation and modify disease courses. Patients with the E148Q variant experiencing typical FMF episodes should receive colchicine, but clinicians should exercise caution regarding alternative diagnoses. Additionally, the E148Q variant may increase acute phase reactants and disease severity in IgA vasculitis. However, to reach definitive conclusions on its treatment-modifying role in PFAPA, universal diagnosis and treatment response criteria should be adopted.
