Abstract The aim was to assess whether subject’s participation in early-phase chemoprevention trials was satisfactory and identify features associated with subjects’ satisfaction. Thirteen trials that investigated a range of candidate agents from 2006 to 2021 by the Cancer Prevention Network were included. The five-item “Was It Worth It?” (WIWI) questionnaire was administered to all subjects at the end of each trial’s intervention or at early termination. Satisfied overall was defined as a participant response of “yes” to the first three questions. Six hundred ninety-one participants from the United States, Canada, Puerto Rico, and Honduras enrolled on a trial. Six hundred fifty-two (94.4%) completed the WIWI questionnaire. Of these, 493 (75.6%) were White, non-Hispanic/Latino; 39 (6.0%) Black, non-Hispanic/Latino; 98 (15.0%) Hispanic/Latino; and 8 (1.2%) of another race/ethnicity. One hundred ninety-three were women (29.6%), 121 (17.5%) were ≥65 years, and 517 (79.3%) participated in a placebo-controlled trial. Eighty-five percent indicated being satisfied overall. Compared with White, non-Hispanic/Latino, the odds of not satisfied overall were 2.96 times higher for Black/Asian/>1 race, non-Hispanic/Latino (P < 0.001) and 0.40 times lower for Hispanic/Latino (P = 0.004). The odds of not satisfied overall was 1.9 times higher when the number of preintervention adverse events experienced was ≥1 (P = 0.012), 1.8 times higher when the percentage of the intervention duration with adverse events was >5% (P = 0.024), and 7.4 times higher for subjects who terminated the intervention early (P < 0.001). These findings can inform the design of future chemoprevention trials and help investigators improve accrual, retention, adherence, and diversity in this underexplored research setting. Prevention Relevance: The five-item “WIWI?” questionnaire, which captures the participant-reported experience of trial participation, gives the subject a voice in the development of new chemopreventative agents. This study in 652 subjects looked at satisfaction with participation in early-phase chemoprevention trials for higher-risk, cancer-free men and women. See related Spotlight, p. 7

ABSTRACT Introduction Children with hepatoblastoma (HB) and other solid tumors frequently undergo intraoperative blood transfusion (IBT) with unknown impact on oncologic outcomes and scant data to guide transfusion in this population. This study tested the hypothesis that IBT is associated with poorer survival in children with HB. Methods A multicenter retrospective observational study of patients aged <18 years with HB who underwent primary tumor resection, including liver transplantation, from 2010 to 2019 was performed at 19 institutions. The association of IBT with risk of recurrence and death were determined using propensity score reweighted (PSR) Cox proportional hazards regression analyses. Results There were 338 patients identified who met inclusion criteria and had sufficient data for inclusion. Of those, 257 (76%) received IBT, including 253 (98%) who received packed red blood cells (pRBC), 84 (33%) who received plasma, and 28 (11%) who received platelets. IBT was associated with higher pretreatment extent of disease ( p < 0.001), presence of annotation factors (+VPEFR: 50%, n = 129 vs. 37%, n = 30, p = 0.035), and complex resections (extended, meso‐, or total hepatectomy: 54%, n = 139 vs. 27%, n = 22, p < 0.001); these differences were mitigated after applying propensity score weighting. Patients who received IBT had greater postoperative hemoglobin (g/dL) (median 10 (I8–11) vs. 9 (8–10), p = 0.013) and required more postoperative plasma and platelet transfusions ( p < 0.05). Median follow‐up was 4.4 (2.0–8.3) years. Compared with non‐IBT patients, those with IBT had higher incidence of death (PSR HR 2.35, 95% CI 1.10–5.02). Recurrence did not significantly differ across groups (PSR HR = 0.82, 95% CI 0.45–1.48). Conclusion IBT was associated with greater hazard of death. Postoperative hemoglobin levels suggested that unnecessary transfusions occurred and a pRBC‐focused approach to IBT led to coagulopathy. Development of optimal transfusion strategies for HB are needed to minimize unnecessary transfusions.

ABSTRACT Objective Reconstruction of complex midface defects is challenging. Vascularized composite flaps are often needed to replace missing premaxilla and palatal bone, oral and sinonasal lining, as well as external facial skin in these defects. The submental flap has the potential to provide all these various tissues with the added advantage of matching facial skin color and hair‐bearing qualities and is available within the surgical field. Methods A retrospective cohort study was carried out at Mayo Clinic Arizona. Patients who had an osteocutaneous submental flap reconstruction for a midface defect between January 2002 and November 2017 were identified using a prospectively collected database. Patient demographics, surgical characteristics, short‐term and long‐term complications were collected. Results The osteocutaneous submental island flap was utilized for reconstruction of midfacial defects in 15 patients. The mean age of the cohort was 60.45 ± 16.57 years, with a male predominance (73.3%). Squamous cell carcinoma was the most common pathology ( n = 12, 80%). The mean soft tissue component of the flap utilized for reconstruction was 50cm 2 , with the mean bone length harvested being 4.4 cm. Short‐term complications occurred in three (20%) patients requiring re‐exploration in the operating room. One patient ultimately experienced flap failure. Conclusion The pedicled osteocutaneous submental flap is a highly versatile flap that offers excellent bony and soft tissue reconstruction for complex midfacial defects. It provides a rapid, reliable option with minimal donor morbidity and a unique color match to the facial defect. Level of Evidence 3.

ABSTRACTAimTo report a novel case of biopsy‐proven, mass spectrometry‐confirmed, wild‐type transthyretin amyloidosis (ATTRwt) in nerve.MethodsThe patient was identified and evaluated in the peripheral nerve clinic. Our nerve laboratory's pathology database and the literature were searched for prior evidence of pathologically confirmed cases of ATTRwt.ResultsA 94‐year‐old man with a history of lumbar spinal stenosis presented to the neurology clinic with subacute‐on‐chronic progressive, upper limb predominant weakness along with numbness and tingling paresthesia. Electromyography (EMG) revealed multiple mononeuropathies involving the right median nerve at the wrist, right ulnar nerve, and right distal radial nerve superimposed upon an axonal predominant peripheral neuropathy along with multilevel lumbosacral radiculopathies. Extensive serology for causes of neuropathy and multiple mononeuropathies returned unremarkable. A diagnostic right superficial radial nerve biopsy was performed and showed congophilic material within a small epineurial vessel wall in the nerve tissue. Amyloid typing by mass spectrometry was performed and revealed ATTRwt. TTR gene sequencing returned normal. The patient was diagnosed with ATTRwt neuropathy and started on diflunisal therapy for neuropathy treatment.ConclusionThis case confirms the presence of ATTRwt deposition directly in nerve tissue as the likely cause of the patient's large fiber and multiple mononeuropathies, expanding our current understanding of ATTRwt‐associated disease. Proving the direct association of ATTRwt and neuropathy may open up amyloid‐specific treatments for this disease.

Abstract Background Progressive Supranuclear Palsy (PSP) is a rare and severe neurodegenerative tauopathy characterized by diverse clinical phenotypes, including Richardson's syndrome (PSP‐RS), PSP‐parkinsonism (PSP‐P), PSP‐progressive gait freezing (PSP‐PGF), and PSP‐corticobasal syndrome (PSP‐CBS). Significant geographic variation exists in prevalence, clinical presentations, and prognosis. Objectives This global review aims to systematically evaluate the epidemiological variation, clinical phenotypes, diagnostic practices, and management strategies for PSP, focusing on regional disparities and identifying influencing genetic and environmental factors. Methodology A comprehensive literature search following PRISMA guidelines was conducted, analyzing studies reporting PSP epidemiology, phenotypes, diagnostic criteria, risk factors, treatments, and prognoses. Data were categorized into epidemiology, risk factors, clinical presentations, diagnosis, treatment accessibility, and outcomes, considering geographic variation. Results Global PSP prevalence ranges between 5–6.4 per 100,000, influenced by diagnostic criteria and healthcare infrastructure. Clinical manifestations commonly include supranuclear gaze palsy, frequent falls, cognitive impairment, and motor dysfunction. Prognosis significantly varies with subtype; PSP‐RS shows rapid progression and shorter survival (5–7 years), whereas PSP‐P has a milder clinical course (8–12 years). Regional variations highlight differences in genetic predispositions, notably the MAPT H1 haplotype, environmental risk factors such as dietary neurotoxins and industrial pollutants, and accessibility to comprehensive healthcare services. Diagnostic accuracy has improved with the adoption of MDS‐PSP criteria, facilitating recognition of diverse phenotypes. Conclusions Regional disparities in PSP prevalence, phenotypic presentation, and healthcare accessibility underscore the importance of standardized diagnostic criteria, targeted genetic and environmental studies, and equitable healthcare strategies. Enhanced global collaboration is essential for improving PSP diagnosis, management, and patient outcomes worldwide.

Abstract Context Patients with endogenous hypercortisolism experience glucocorticoid withdrawal syndrome (GWS) after surgery. Meditation may be an effective intervention to alleviate the severity of GWS. Objective To determine the acceptability of a portable, wearable electroencephalography device for guided meditation (MUSE headband) and the impact of MUSE use on GWS and quality of life 12 weeks postsurgery. Methods We conducted a single-center prospective cohort study of adults with endogenous hypercortisolism undergoing curative surgery from 2019 to 2024. Patients had baseline and postsurgical assessments over 12 weeks. The study comprised patients using MUSE for ≥ 6 weeks (MUSE cohort) and patients matched by age, sex, BMI, hypercortisolism type, and glucocorticoid type at 1:4 ratio. Quality of life and GWS symptoms were assessed with AddiQoL, CushingQoL, and 36-item Short Form Health Survey mental and physical component (SF-36 MCS and PCS) questionnaires. Results MUSE was offered to 52 patients, and 22 (42%) used MUSE for ≥ 6 weeks within 12 weeks after surgery. At baseline, compared to 88 matched subjects, 22 MUSE participants demonstrated similar prevalence of comorbidities and clinical and biochemical hypercortisolism severity, but lower AddiQoL (mean 73 vs 66, P = .031) and SF-36 MCS (mean 39 vs 33, P = .022). At 12 weeks, these differences in quality of life were no longer present. After adjusting for age, sex, BMI, clinical severity score, and baseline quality of life, MUSE use was an independent predictor of improved SF-36 PCS at 12 weeks postsurgery (beta 4.2, 95% CI: 0.5-7.9, P = .026). Conclusion Postsurgical meditation intervention may improve physical symptoms and accelerate recovery.
