Abstract Background Topical steroid withdrawal syndrome (TSW) is an adverse event following discontinuation of topical corticosteroids (TCS) and is of growing interest among patients and dermatologists. The absence of well-defined diagnostic criteria and limited insights into the pathomechanisms make diagnosis and future research challenging. Objectives To propose preliminary diagnostic criteria for TSW with the erythemato-oedematous subtype applicable for adult and paediatric populations using a Delphi consensus approach informed by a thorough literature review that summarizes the signs, symptoms and histology of TSW. Methods Eleven clinicians experienced in diagnosing and treating suspected TSW in both children and adults participated in a three-round modified Delphi process. Two rounds of surveys were conducted, with items ranked using a 5-point Likert scale. A predefined consensus threshold of ≥ 75% was established for any one feature to be deemed important. The third round involved a live video conference where the panel reached a consensus on essential diagnostic criteria. Results The panel identified 18 critical diagnostic items, encompassing elements from the patient’s clinical history, signs and symptoms. This includes history of escalating TCS requirement, morphology and distribution differing from primary condition, regional or generalized spontaneous neuropathic pain and severe burning sensation of the skin. Conclusions Differentiating TSW from conditions such as severe atopic dermatitis remains challenging. By emphasizing the common signs and symptoms of TSW, we aim to encourage discussions among healthcare professionals and progress towards the development of a reliable diagnostic tool.

Abstract Background Thrombotic Thrombocytopenic Purpura (TTP) is a rare, typically acquired disorder due to an immune-mediated deficiency of ADAMTS13, a metalloprotease responsible for cleaving large multimers of von Willebrand Factor (vWF). In the absence of ADAMTS13 activity, ultra-large vWF multimers accumulate, promoting widespread platelet aggregation and microvascular thrombosis. This consumptive cascade leads to thrombocytopenia, microangiopathic hemolytic anemia, fever, neurological symptoms, and rarely renal dysfunction. Although therapeutic plasma exchange (TPE) has long been the cornerstone of TTP treatment, the FDA approved Caplacizumab as a first-line treatment for TTP in 2019. This drug is a bivalent single-domain antibody that binds to the A1 domain of vWF and prevents its interaction with platelets, thus effectively interrupting the pathogenic cascade, which is associated with a risk of bleeding. Methods We conducted a retrospective cohort study using the TriNetX Global Collaborative Network, comprising data from 152 healthcare organizations. Adults (≥18 years) with a diagnosis of TTP who received Caplacizumab plus TPE were compared to patients with TTP who received TPE alone. 1:1 propensity score matching (PSM) was performed to balance characteristics between cohorts. The primary outcomes assessed were all-cause mortality and major bleeding events over a period of 1 month. Results A total of 4084 patients with TTP were identified, of whom 356 received caplacizumab with TPE and 3728 received TPE. After PSM, 2 balanced cohorts were created: C+P (Caplacizumab + TPE), P only (TPE), each comprising 356 patients. The average age in C+P and P only, after PSM, was 50.4 +/- 16.2 and 50.8 +/- 16.2 years, respectively. Females formed 65.7% of both C+P and P only, and males accounted for 28.4% and 28.7% of C+P and P only, respectively. 2.8% patients in C+P and 7.06% patients in P only had all-cause mortality at the end of 1 month. One-month all-cause mortality was significantly lower in C+P (2.8%) compared to P only (7.06%), with an odds ratio (OR) of 0.385 (95% CI 0.182 to 0.814, p=0.010). Upon assessment of bleeding outcomes, no statistically significant risk difference was noted between the 2 groups, with the odds ratio being 0.974 (95% CI 0.399 to 2.379, p=0.954). Conclusion Our large database study suggests that the addition of caplacizumab to standard TPE therapy is associated with a reduction in one-month all-cause mortality in patients with TTP, without a corresponding increase in major bleeding. However, given the lack of granular clinical data, such as contraindications to caplacizumab use, it is possible that patients who received TPE alone were inherently at a higher risk. As such, while these findings support the potential benefit of early caplacizumab use, they should be interpreted with caution and warrant prospective validation to confirm causality and assess long-term outcomes.

ABSTRACT Alzheimer's disease (AD), a leading cause of dementia in the elderly, is traditionally characterized by neurodegeneration driven by amyloid‐beta plaques and tau tangles. However, emerging evidence reveals that AD's impact extends beyond the brain, significantly affecting skeletal health. This review integrates clinical and transgenic mouse model data to elucidate the mechanistic interplay between AD pathology and bone metabolism. AD patients exhibit increased risk for hip fractures and low bone mineral density (BMD), independent of cognitive impairment severity. We found altered calcium and alkaline phosphate levels in the blood of patients with mild cognitive impairment and AD, as assessed from the Alzheimer's Disease Neuroimaging Initiative data. Convergent risk factors—age, sex, APOE4 genotype, smoking, and vitamin D deficiency—contribute to both neurodegeneration and bone fragility. Key molecular pathways, such as Wnt/β‐catenin signaling and TREM2‐mediated osteoclast regulation, underscore shared mechanisms driving disease pathology in both systems. Mouse models of AD consistently demonstrate disrupted bone remodeling, impaired osteoblast function, and heightened osteoclast activity. Therapeutic strategies targeting overlapping pathways, including lithium, anti‐FSH antibodies, and NF‐κB inhibitors, show promise in mitigating both cognitive decline and bone loss. Collectively, these insights advocate for a more integrated view of AD that includes skeletal comorbidities, potentially guiding the development of dual‐purpose interventions.

Importance Despite treatment advances, metastatic recurrence continues to be a leading cause of morbidity and mortality. Empirical data on the incidence and survival after metastatic recurrence remain limited, as cancer registries historically do not collect data on recurrence. Objective To estimate the cumulative incidence (CMI) of metastatic recurrence among adolescents and young adults diagnosed with earlier-stage disease and compare survival to those with metastatic disease at diagnosis. Design, Setting, Participants This was a retrospective cohort study of adolescents and young adults aged 15 to 39 years who were diagnosed with nonmetastatic cancers from 2006 to 2018. Adolescents and young adults were identified from the California Cancer Registry linked with statewide hospitalization, emergency department, and ambulatory surgery encounters from the California Department of Health Care Access and Information. Data were analyzed from December 2023 to June 2025. Exposures Cancer types, including melanoma, sarcoma, and breast, cervical, colorectal, testicular, and thyroid cancers. Main Outcomes and Measures Metastatic recurrence was identified using International Classification of Diseases, Ninth Revision, Clinical Modification, and Tenth Revision, Clinical Modification, metastatic disease codes at least 6 months after cancer diagnosis or from an underlying cancer cause of death. Follow-up was through December 31, 2020. Results Of a total of 48 406 adolescents and young adults (median [IQR] age at diagnosis, 33.0 [28.0-37.0] years; 67.4% female), 9.2% had metastatic disease at diagnosis, and 9.5% had metastatic recurrence. Among 43 935 adolescents and young adults who presented with nonmetastatic disease, the 5-year CMI of metastatic recurrences was highest among patients with sarcoma (24.5%; 95% CI, 22.6%-26.6%) and colorectal cancer (21.8%; 95% CI, 20.3%-23.4%) and intermediate for cervical (16.3%; 95% CI, 15.0%-17.6%) and breast (14.7%; 95% CI, 14.0%-15.4%) cancers. The CMI for metastatic recurrence increased with increasing stage at diagnosis, with 5-year CMIs higher than 30% for all stage III cancers (except thyroid). The 5-year CMI of metastatic recurrence also increased over time for cervical cancer (2006-2009: 12.7% [95% CI, 10.8%-14.8%]; 2015-2018: 20.4% [95% CI, 17.5%-23.6%]) and decreased for colorectal cancer (2006-2009: 24.4% [95% CI, 21.3%-27.6%]; 2015-2018: 19.2% [95% CI, 16.4%-22.2%]). Survival after metastatic recurrence was worse than metastatic disease at diagnosis for all cancer types, except for testicular and thyroid cancers. Conclusions and Relevance The findings from this cohort study highlight the overall burden of metastatic disease in adolescents and young adults, expanding the knowledge of metastatic recurrences that help improve care for adolescent and young adult survivors throughout the cancer survivorship spectrum.

Abstract Despite concerns about the toxicity of allogeneic hematopoietic cell transplantation (alloHCT) in older patients, prospective data characterizing prevalence or risk stratification for geriatric morbidity such as disability or frailty are limited. We prospectively assessed the prognostic impact of the novel composite health assessment risk model (CHARM), a score established to predict 1-year nonrelapse mortality (NRM), among 1105 patients aged ≥60 years enrolled on the Bone Marrow Transplant Clinical Trials Network Study 1704. Secondary end points were assessed post-alloHCT at day 100 (D100), D180, and D365 in multivariable models adjusted with predetermined clinical variables. Among alloHCT survivors, the prevalence of disability by instrumental activities of daily living (IADL), frailty by the Physical Frailty Phenotype, and physical function impairment by Patient Reported Measurement Information System (PROMIS) was highest at D100 and lower on D180 and D365. Higher CHARM scores were independently associated with greater disability (coefficient, −0.64; 95% confidence interval [CI], −0.85 to −0.43; P< .001), increased frailty (coefficient, 0.19; CI, 0.081-0.31; P< .001), worse PROMIS physical function, greater PROMIS depression, increased serious organ toxicity by D100, more cognitive decline at D100, and higher mortality after acute graft-versus-host disease (GVHD) but not significantly associated with PROMIS anxiety or acute GVHD. Higher CHARM scores predicted worse disability-free survival (odds ratio [OR], 2.03; CI, 1.66-2.48; P< .001) and lower frailty-free survival (OR, 2.00; CI, 1.61-2.49). In summary, CHARM is an independent prognostic scoring system not only for NRM but also for geriatric morbidity and functional limitation–free survival through 1 year after alloHCT. Pre-alloHCT CHARM is a novel tool to aid shared decision-making for older patients. This trial was registered at www.clinicaltrials.gov as #NCT03992352.

Abstract Introduction Penile augmentation or penis enlargement surgery refers to any technique aimed at enhancing penile length or girth. These male enhancement surgical techniques can increase total penile length, either flaccid or erect, while others add to the penile shaft’s girth and/or glans size. Proposed strategies include physical methods such as various penile exercises, mechanical traction devices, and medical therapy, while surgical interventions include cosmetic and phallic reconstructive techniques and use of fillers, sleeves, grafts, and flaps to augment penile size. Objectives The International Consultation on Sexual Medicine (ICSM) consensus statements provide evidence-based recommendations and aim to guide a clinical framework in penile aesthetic and augmentation. Methods A comprehensive literature search was conducted to identify published literature relevant to penile augmentation or enhancement. Preliminary consensus was presented to the delegates attending the 5th ICSM meeting, and feedback was incorporated into the final document. Results Twenty new recommendations are provided with corresponding levels of evidence and grades of recommendation. Conclusions Due to the controversies and lack of longer-term data regarding penile augmentation and cosmetic procedures, comprehensive assessments and careful patient counseling weighing the pros and cons, as well as potential complications, are mandatory before embarking on any treatment. Surgeons should be experienced in anatomy and various surgical techniques, and it is important to individualize surgical options based on patient condition(s) and needs, surgeon expertise, and local resources.

Abstract Introduction There is no ideal treatment for Peyronie’s Disease (PD) since every patient has different needs with varying perceived risks versus benefits of individual treatment options, coupled with the degree of impact relating to PD on sexual function and beyond. Objectives The 5th International Consultation on Sexual Medicine (ICSM) guideline on PD provides an update to the previous ICSM with an aim to provide a clinical framework and best-evidenced consensus recommendations to assist clinicians in managing PD. Methodology Available literature was reviewed, and a modified Delphi consensus was undertaken by leading sexual medicine experts to achieve a set of Quality of Evidence and strength of recommendations. This guideline was developed as an authoritative best-evidenced consensus incorporating state-of-the-art knowledge and contemporary literature. Results A total of thirty-one recommendations were made on PD guidelines. New updates to the 4th ICSM on PD have been made in definition, pathophysiology, and treatment strategies. The presence of penile pain with erection could occur in the chronic phase due to torque or stretch on the penile scar and surrounding tissue. Oral therapy works best during the acute phase and should be provided concurrently with other treatment modalities. Penile traction therapy can reduce penile deformity as monotherapy or may be offered as part of a multimodal therapy approach. There is no convincing evidence supporting cellular-based therapy. The type of plication procedure used depends on the surgeon and patient preference, although excision of the tunica followed by plication may have a higher complication rate. There is currently no ideal graft, and graft contracture can occur postoperatively. Adjunctive procedures such as penile modeling, tunical plication, plaque incision/excision and grafting can be performed when penile deformity and/or penile curvature persist following penile prosthesis implantation. Conclusions The management of PD should be individualized based on the patient’s needs and preferences while balancing the benefits and risks of each treatment option.

Abstract The brain avidly consumes glucose to fuel neurophysiology. Cancers of the brain, such as glioblastoma (GBM), relinquish physiological integrity and gain the ability to proliferate and invade healthy tissue. How brain cancers rewire glucose utilization to drive aggressive growth remains elusive. Here, we infused 13C-labeled glucose into patients and mice with brain cancer, coupled with quantitative metabolic flux analysis, to map the fates of glucose-derived carbon in tumor vs. cortex. Through the first direct and comprehensive measurements of carbon and nitrogen labeling in both cortex and glioma tissues, we uncover profound metabolic transformations. In human cortex, glucose carbons fuel essential physiologic processes including TCA cycle oxidation and neurotransmitter synthesis. Conversely, gliomas downregulate these processes and scavenge alternative carbon sources such as amino acids from the environment, repurposing glucose-derived carbons to generate molecules needed for proliferation and invasion. Targeting this metabolic rewiring in mice through dietary amino acid modulation selectively alters GBM metabolism, slows tumor growth, and augments the efficacy of standard-of-care treatments. These findings illuminate how aggressive brain tumors exploit glucose to suppress normal physiological activity in favor of malignant expansion and offer potential therapeutic strategies to enhance treatment outcomes.

Abstract BACKGROUND The phase III ECOG-ACRIN E3F05 trial tested whether combined therapy with radiation and concomitant followed by adjuvant temozolomide is more effective than radiation alone in patients with grade II gliomas. The study incorporated 1p/19q analysis but predated assessment of IDH mutational status. We previously reported that the addition of temozolomide to radiotherapy significantly improved overall survival in grade II gliomas, with similar hazard ratios in co-deleted (0.56) and non-codeleted (0.53) tumors. Herein we incorporate the results of DNA methylation profiling to examine outcomes in IDHmt, non-codeleted subjects as well as co-deleted ones. METHODS All 172 subjects underwent 1p/19q co-deletion analysis as a stratification factor, 1p and 19q deletion analysis was performed on formalin-fixed paraffin-embedded (FFPE) gliomas by Fluorescent In Situ Hybridization (FISH) following standard methods, 97/172 (56.3%) had tissue with 60% or more tumor content available for DNA methylation profiling using Heidelberg classifier v12 and Bethesda Classifier 2.0 to ascertain classification as IDH mutant glioma and alternative evaluation of 1p/19q co-deletion status. RESULTS Of the 172 subjects, 74 (43.0%) had 1p/19q codeletion by FISH, 38 (22.1%) were IDHmt without codeletion, 14 (8.1%) were IDHwt, and 46 (26.7%) were non-codeleted with unknown IDH status (these include n=4 pts originally classified as 1p/19q undetermined). With a median follow-up of 130 months, the addition of TMZ to RT improved OS in patients with IDHmt, non-codeleted tumors (HR 0.15 (0.03-0.74)) and 10-year OS from 39% to 80%. In codeleted tumors, the addition of TMZ improved OS (HR 0.51 (0.19-1.42)) and 10-year OS from 68% to 90%. CONCLUSION The addition of temozolomide to radiation improves overall survival in both co-deleted and IDHmt, non-co-deleted grade II gliomas.
