Background: Pulsatile tinnitus (PT) is frequently caused by venous sinus stenosis and may be associated with idiopathic intracranial hypertension (IIH). Venous sinus stenting (VSS) directly addresses venous outflow obstruction and has emerged as a therapeutic option; however, outcome data remain heterogeneous. We performed an updated systematic review and meta-analysis to evaluate the efficacy and durability of VSS for PT and to compare outcomes between IIH-associated and isolated PT. Methods: MEDLINE, Scopus, and Web of Science were searched from inception through December 2025 following PRISMA guidelines. Clinical studies reporting PT outcomes after VSS were included. Random-effects meta-analyses of proportions were conducted to estimate pooled rates of overall improvement, complete resolution, and recurrence. Prespecified subgroup analyses compared IIH versus isolated PT. Results: Thirty-two studies comprising 850 patients were included (641 with IIH; 209 with isolated PT). Venous sinus stenosis accounted for 90.3% of treated etiologies. The pooled rate of overall PT improvement was 89.8% (95% CI, 85.5-92.9). Complete resolution occurred in 87.1% (95% CI, 82.5-90.6). Recurrence at last follow-up was 10.9% (95% CI, 8.3-14.2). Improvement and complete resolution rates did not differ significantly between IIH and isolated PT. Recurrence was higher in IIH (12.0%) than in isolated PT (5.7%), without reaching statistical significance. Conclusions: VSS is associated with high rates of PT improvement and complete resolution with low recurrence. Recurrence trends appear higher in IIH, suggesting underlying pathophysiology may influence durability.

ABSTRACT Lupus nephritis requires long-term immunosuppressive therapy, which is often associated with severe systemic side effects. Therefore, new therapeutic strategies that maintain high efficacy while minimizing adverse effects is essential. Although nanomedicine has advanced systemic and kidney-targeted drug delivery, a reliable method for glomerulus-specific delivery is lacking. Collagen IV (Col4)-alpha 3, located in the glomerular basement membrane (GBM) at the blood–tissue interface through fenestrated capillary endothelium, represents an ideal target for glomeruli delivery. Herein, we developed a novel liposomal nanoparticle conjugated with a Col4-alpha 3 binding peptide (Col4-α3-NPs) for selective glomerular targeting. Prednisolone-loaded Col4-α3-NPs were administered to lupus-prone mice twice weekly for 8 weeks. Kidney injury and function were evaluated biweekly, and renal immune cell populations were analyzed by flow cytometry at study completion. The results show that rhodamine-labeled NPs predominantly accumulate in kidney glomeruli 48 hours after intravenous injection. The Col4-NP system demonstrated stable and prolonged release of the encapsulated drug for over 48 hours. Lupus-prone mice treated with prednisolone-loaded Col4-NPs showed significantly improved renal function and histology, including a 30% increase in glomerular filtration rate (GFR), a 56% reduction in proteinuria, and decreased IgG deposition and fibrosis. Notably, treatment also enhanced renal regulatory T cell (Treg) populations. These findings suggest that glomerulus-targeted Col4-α3-NPs hold significant translational promise. This platform may offer an effective, site-specific treatment for lupus nephritis while minimizing systemic side effects and could be adapted for other glomerular diseases requiring targeted therapy.

We previously reported 5-year results of 57 patients with major acetabular defects (Paprosky 2B through 3B) who underwent full (31) or half (26) cup-cage reconstructions. This study provides an update with 8.8-year mean follow-up. The 10-year cumulative incidence of and survivorship free from revision, reoperation, and complications were estimated. The 10-year cumulative incidence of revision was 14% for full and 12% for half constructs. The incidence of revision for aseptic loosening was 4.3% and 4.6%, respectively. The 10-year survivorship free from aseptic loosening for patients with pelvic discontinuity was 88.9% (95% confidence interval [CI], 70.6% to 100%) and 85.7% (95% CI, 61.8% to 100%), respectively; no patient without pelvic discontinuity required revision for aseptic loosening. The 10-year cumulative incidence of complications was 42% for all patients, including a 15% incidence of dislocation. Thus, both full and half cup-cage constructs provided durable fixation for complex acetabular bone loss at 10 years, although dislocation remains a concern. Level of Evidence: Therapeutic Level IV .

Background: Although skin cancer survivors have an increased risk of future malignancies, many are unaware of this and may not undergo preventative screening. Objective: To evaluate skin cancer survivors’ prevalence of breast, colorectal, cervical, and lung cancer screening. Methods: This is a retrospective cross-sectional analysis of The Behavioral Risk Factor Surveillance System database from 2017 to 2021 comparing skin cancer, other cancer, and non-cancer controls. Multivariate analysis compared screening rates, controlled for socioeconomic, chronic disease, and behavioral factors. Results: Compared to non-cancer controls, skin cancer survivors had higher odds of undergoing screening for breast (odds ratios [OR]: 1.35, 95% confidence interval [CI] 1.20–1.51), colorectal (OR 1.53, 95% CI 1.40–1.66), and cervical cancer (OR 1.32, 95% CI 1.12–1.56). Lung cancer screening rates were low and similar between skin cancer survivors and non-cancer individuals (OR 1.21, 95% CI 0.84–1.74). In a subset analysis of skin cancer survivors, those who had melanoma were less likely to be screened for breast and colorectal cancer. Limitations: This study is based on anonymous, national survey data, relying on patient recall of their health information. Conclusion: Skin cancer survivors undergo cancer screenings for breast, colorectal, and cervical cancer at higher rates compared to non-cancer controls. Melanoma survivors have lower rates of breast and colorectal screening compared to non-melanoma skin cancer survivors. Skin cancer survivors should be reminded of preventive cancer screening, particularly for lung cancer.

Background: Alopecia is a burgeoning area of patient interest and dermatologic investigation. Alopecia following a solid organ transplant has been relatively unexplored, despite the potential for significant symptomatic and psychological impact on patients posttransplant. Objective: We set out to study alopecia in patients following solid organ transplants, including presentation, etiology, evaluation, and management. Methods: We performed a retrospective analysis of patients who underwent solid organ transplant without a preceding history of alopecia at a single center between January 1, 2011, and December 31, 2020, to record new alopecia diagnoses posttransplant. Demographic data, transplant type, immunosuppressive regimen, and type of alopecia were all collected. Results: Between 2011 and 2020, a total of 3,732 patients underwent a solid organ transplant with a median age of 58 (range: 18-82) years. Sixty-two percent were men, 72.5% were White, and 8.4% identified as Hispanic or Latino. Out of 3,732 patients who underwent a solid organ transplant, 39 (1%) subsequently developed alopecia. Risk of alopecia was higher in females (hazard ratio [HR] = 12.26, P < .001), Hispanics (HR = 2.49, P = .043), and pancreas transplant patients (HR = 24.26, P < .001). Limitations: This is a retrospective review. Conclusion: In this study, alopecia was rare after a solid organ transplant, but further investigation is needed to assess for potential underdiagnosis of alopecia following transplant and the higher risks reported in certain populations.

At a time when there was no unifying hypothesis and no broadly effective treatments for heart failure with a preserved ejection fraction (HFpEF), it was proposed that HFpEF represented a multitude of different disorders. Accordingly, characterization of phenotypic heterogeneity was envisioned as a means of identifying novel causal pathways that could lead to new treatments while simultaneously discerning patients who would selectively benefit from a specific therapy. However, efforts over the past decade to characterize phenotypic diversity in diverse and complex ways have not achieved these goals. Subgroup analyses of neutral HFpEF trials have failed to reliably identify responders to treatments. Neither proteomics nor unsupervised cluster analysis across multiple phenotypic domains has yielded reproducible results (even in the same dataset), elucidated novel mechanistic pathways for new drug development, or identified patients most likely to benefit from treatment. In marked contrast to these efforts to characterize phenotypic heterogeneity, large-scale trials in HFpEF enrolled patients using broad eligibility criteria, and they established the benefits of sodium-glucose cotransporter 2 inhibitors and mineralocorticoid receptor antagonists without evidence for subgroup effects. However, it is noteworthy that patients enrolled in recent large-scale HFpEF trials were characterized by general uniformity with respect to the presence of excess adiposity, with central obesity being a feature of the vast majority of enrolled participants. Of note, patients with obesity showed particularly large benefits when treated with effective drugs for HFpEF. These observations raise the possibility that, if these trials had permitted the participation of patients with class III obesity or with lower natriuretic peptide levels, the magnitude of the observed treatment effects might have been greater than originally reported. These findings are consistent with a central role for visceral adiposity (and the secretion of an altered suite of adipokines) in the pathogenesis of HFpEF. Therefore, because the field of HFpEF has a unifying hypothesis (applicable to the large majority of patients), enrolled a broad population of patients in large-scale trials without subgroup interactions, and has several broadly applicable effective treatments (as is true for heart failure with a reduced ejection fraction), the motivation to characterize phenotypic heterogeneity in HFpEF in complex ways may no longer be supported or needed.
