Prostate-specific membrane antigen (PSMA) PET is a powerful tool for prostate cancer staging and restaging, providing higher sensitivity and specificity than conventional imaging. The recognition of interpretive pitfalls led to the development of various scoring systems and frameworks, which in turn created challenges for consistent interpretation. The Prostate Cancer Molecular Imaging Standardized Evaluation (PROMISE) version 2 classification integrates the five-point PRIMARY score for assessing local disease, the molecular imaging TNM stage for disease extent, and the PSMA expression score to assess eligibility for PSMA-targeted radioligand therapy. The PSMA Reporting and Data System (PSMA-RADS) classifies PSMA PET/CT findings on the basis of the likelihood of presence of prostate cancer. For assessing therapy response, PSMA PET Progression (PPP) criteria focus on new lesions and clinical or biochemical progression, whereas Response Evaluation Criteria in PSMA PET/CT (RECIP 1.0) assess new lesions and changes in total PSMA-positive total tumor volume. The European Association of Nuclear Medicine (EANM) E-PSMA guideline and EANM-Society of Nuclear Medicine and Molecular Imaging procedure guidelines provide standardized reporting recommendations, incorporating elements from existing systems such as PROMISE, PSMA-RADS, and PPP. Nevertheless, such systems can be essential for optimizing prostate cancer management and facilitating communication among imaging professionals, clinicians, and patients. This article outlines these systems and discusses potential strengths and weaknesses.

Social media can benefit prostate cancer care through education and empowerment, but also have the potential for exposure to misinformation, leading to adverse health and/or economic impacts for patients and damaging the patient-physician relationship. Clinicians should promote digital health literacy and provide recommended sources of reliable online content for additional information.

PURPOSE OF REVIEW/UNASSIGNED:As the overdose crisis evolves, it is important to monitor fentanyl consumption patterns. This review provides an overview of recent findings regarding illegally manufactured fentanyl (IMF) availability, use, and associated harms in the US. RECENT FINDINGS/UNASSIGNED:Availability of IMF has increased, especially in pill form, and the increasing adulteration of IMF with veterinary tranquilizers such as xylazine complicates overdose response. Prevalence in the general population based on self-reported IMF use is rare, and likely underestimated. Transitions from injection to smoking have been documented in recent years, particularly in the western US. Fentanyl-stimulant polysubstance use has also been observed increasingly among IMF-related overdose deaths. SUMMARY/UNASSIGNED:Shifts in routes of administration, availability of counterfeit pills containing fentanyl, and common adulterants add complexity to the landscape of IMF use and related harms. Additional data is needed for monitoring changes in consumption patterns to inform prevention and harm reduction efforts.

BACKGROUND/UNASSIGNED:Despite their efficacy, medications for opioid use disorder (MOUD) remain underutilized in patients with infections from intravenous opioid use (I-IOU). This study evaluates the impact of an Expanded MOUD Access Initiative (EMAI) on MOUD uptake and other clinical outcomes in patients hospitalized for I-IOU at an institution without addiction medicine consultation. METHODS/UNASSIGNED:We performed a retrospective pre-post study of hospital admissions for I-IOU before (January 2019-June 2021) and after (January 2022-December 2023) EMAI introduction. Data was collected via chart review. The EMAI eliminated restrictions on methadone use and established a new order set for buprenorphine inductions. The primary outcome was MOUD receipt; secondary outcomes included patient directed discharge (PDD) and 30-day re-hospitalization. RESULTS/UNASSIGNED:There were 129 hospitalizations prior to the intervention (control) and 98 after (EMAI). MOUD receipt was significantly higher in the EMAI group (75.5% vs 31.0%; OR, 6.86 [95% CI, 3.84-12.61]). In patients not receiving MOUD prior to admission (n = 176), new inductions occurred more frequently in the EMAI group (68.0% vs 11.9%; OR, 15.76 [95% CI, 7.50-35.78]). PDD was lower in the EMAI group (23.5% vs 48.8%; OR, 0.32 [95% CI, 0.10-0.57]), as was 30-day re-hospitalization (12.2% vs 22.5%; OR, 0.48 [95% CI, 0.22-0.98]). In a multivariable logistic regression model, the EMAI was the only variable to show a statistically significant association with MOUD receipt (aOR, 6.89 [95% CI, 3.75-13.11]). CONCLUSIONS/UNASSIGNED:The EMAI was associated with increased MOUD uptake, reduced PDD, and fewer 30-day re-hospitalizations despite the lack of addiction medicine consultation.

RATIONALE AND OBJECTIVES/OBJECTIVE:To evaluate the performance, stability, and decision-making behavior of large language models (LLMs) for title and abstract screening for radiology systematic reviews, with attention to prompt framing, confidence calibration, and model robustness under disagreement. MATERIALS AND METHODS/METHODS:We compared five LLMs (GPT-4o, GPT-4o mini, Gemini 1.5 Pro, Gemini 2.0 Flash, Llama 3.3 70B) on two imaging-focused systematic reviews (n = 5438 and n = 267 abstracts) using binary and ternary classification tasks, confidence scoring, and reclassification of true and synthetic disagreements. Disagreements were framed as either "LLM vs human" or "human vs human." We also piloted autonomous PubMed retrieval using OpenAI and Gemini Deep Research tools. RESULTS:LLMs achieved high specificity and variable sensitivity across reviews and tasks, with F1 scores ranging from 0.389 to 0.854. Ternary classification showed low abstention rates (<5%) and modest sensitivity gains. Confidence scores were significantly higher for correct predictions. In disagreement tasks, models more often selected the human label when disagreements were framed as "LLM vs human," consistent with authority bias. GPT-4o showed greater resistance to this effect, while others were more prone to defer to perceived human input. In the autonomous search task, OpenAI achieved moderate recall and high precision; Gemini's recall was poor but precision remained high. CONCLUSION/CONCLUSIONS:LLMs hold promise for systematic review screening tasks but require careful prompt design and circumspect human-in-the-loop oversight to ensure robust performance.

Epigenetic aging in early life remains poorly characterized, and patterns of gene expression can provide biologically meaningful insights. Blood DNA methylation was measured using the Illumina EPICv1.0 array and RNA sequencing was performed in blood in 174 adolescent participants (age range: 14-15 years) from the CHAMACOS cohort. Thirteen widely used epigenetic clocks were calculated, and their associations with transcriptome-wide RNA expression were tested using the limma-voom pipeline. We found evidence for substantial shared associations with RNA expression between different epigenetic clocks, including differential expression of MYO6 and ZBTB38 across five clocks. The epiTOC2, principal component (PC) PhenoAge, Hannum, PedBE and PC Hannum clocks were associated with differential expression of the highest number of RNAs, exhibiting associations with 22, 8, 5, 3, and 2 transcripts respectively. Generally, biological clocks were associated with differential expression of more genes than chronological clocks, and PC clocks were associated with differential expression of more genes relative to their CpG-trained counterparts. A total of 17 associations in our study were replicated in an independent adult sample (age range: 40-54 years). Our findings support the biological relevance of epigenetic clocks in adolescents and provide direction for selection of epigenetic ageing biomarkers in adolescent research.

People with HIV are at increased risk of cardiovascular events; thus, care delivery strategies that increase access to comprehensive cardiovascular disease (CVD) risk management are a priority. We report the results of a multi-component telemedicine-based strategy to improve blood pressure control among people with HIV-Assess and Adapt to the Impact of COVID-19 on CVD Self-Management and Prevention Care in Adults Living with HIV (AAIM-High). The AAIM High strategy is a virtual adaptation of our previously published EXTRA-CVD strategy and consisted of hypertension education and six components: nurse-led care coordination (delivered by teleconference or telephone), home systolic blood pressure (SBP) monitoring, evidence-based treatment algorithms, electronic health records tools, technology coach, and communication preferences assessment. People with HIV (n = 74) with comorbid hypertension at three academic medical centers were enrolled in a single arm implementation study from January 2021 to December 2022. Over 12 months, the average patient-performed home SBP decreased by 7.7 mmHg (95% CI -11.5, -3.9). The percentage of patients at treatment goal, defined as average SBP <130 mmHg, increased from 46.0% to 72.5% at 12 months. By adapting to the growing use of telemedicine in healthcare delivery, our study effectively improved hypertension control in people with HIV through a virtual, nurse-led intervention.

BACKGROUND/UNASSIGNED:; environmental injustice) by racial/ethnic segregation (social injustice) on dementia diagnosis in ESKD. METHODS/UNASSIGNED:concentrations (annualized and matched to older adults' residential ZIP code at dialysis initiation) and by segregation scores (Theil's H method). FINDINGS/UNASSIGNED:and segregation. INTERPRETATION/UNASSIGNED:experienced an increased risk of dementia; this risk was particularly pronounced among individuals in high segregation and predominantly minority neighborhoods. Environmental and social injustices likely drive racial and ethnic disparities in dementia for older adults with ESKD, underscoring the need for interventions and policies to mitigate these injustices.

BACKGROUND AND OBJECTIVE/OBJECTIVE:Prostate cancer (PC) is the second most common cancer and a leading cause of death among males. In this systematic review we evaluated cohort studies and randomized controlled trials (RCTs) on the relationship between dietary patterns and PC risk, progression, mortality, and biomarkers. METHODS:A systematic search of MEDLINE, Embase, and Cochrane Central was conducted through June 2024 according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. A total of 63 studies (49 cohort studies, 14 RCTs reports) examining dietary patterns and PC outcomes were included. Study quality was assessed using Critical Appraisal Skills Programme checklists. KEY FINDINGS AND LIMITATIONS/UNASSIGNED:Among males without PC at baseline, plant-based and healthy dietary patterns (eg, higher Healthy Eating Index, lower dietary inflammatory and hyperinsulinemic scores) were generally associated with lower total PC risk. Among patients with PC, Mediterranean, plant-based, and low-inflammatory diets were more consistently linked to lower risk of progression and PC-specific mortality. RCTs testing various diet patterns showed mixed effects on prostate-specific antigen or tumor markers. Limitations include variations in diet definitions, outcomes, and follow-up duration, and residual confounding. CONCLUSIONS AND CLINICAL IMPLICATIONS/CONCLUSIONS:Healthy dietary patterns that support cardiometabolic health may also benefit PC prevention and management. While evidence appears stronger for diet in slowing PC progression after diagnosis, the impact of diet on reducing the risk of other PC outcomes should not be overlooked (eg, risk of developing PC or risk of PC death). Integrated strategies are needed to promote healthy eating, particularly for patients at risk of PC progression, as this population often has higher risk of cardiovascular disease and metabolic disorders such as diabetes.
