Abstract Background: Black or African Americans (AA) with Parkinson’s disease (PD) are underrepresented in both care and research and experience significant health disparities. The existing literature provides limited guidance on how to enhance the engagement of AA individuals in PD care and research, particularly from the perspectives of AA patients, care partners, and healthcare providers. This project aimed to (1) describe the use of Community Engagement (CE) Studios as a community-engaged research approach to inform culturally appropriate and inclusive research and (2) examine factors influencing AA engagement in PD-related activities. Methods: We conducted three CE Studios: one with AA with PD and care partners (N = 6), one with healthcare providers of AA with PD (N = 8), and one with AA with PD, care partners, and healthcare providers (N = 4). Results: The CE Studios informed the design (e.g., cultural appropriateness) and conduct (e.g., accessibility) of the planned PD project, as well as identifying stakeholders to engage with, improving alignment between research and the AA community. We highlighted the importance of multifaceted factors, including environmental (e.g., segregation), biological (e.g., symptoms), sociocultural (e.g., not being invited), and behavioral (e.g., empowerment) domains, which influence AA engagement. Conclusions: The CE Studios method is a feasible and useful approach for understanding the perspectives of AA in PD. It is possible to conduct an in-depth exploration of community perspectives by synthesizing comprehensive analyses and leveraging additional frameworks. These efforts include identifying barriers to engagement, recognizing locally relevant individuals, and refining PD-related care to enhance cultural appropriateness.

Abstract Background Physical activity (PA) is an established protective factor for colorectal cancer (CRC), but it is unclear if genetic variants modify this effect. To investigate this possibility, we conducted a genome-wide gene–PA interaction analysis. Methods Using logistic regression and two-step and joint tests, we analyzed interactions between common genetic variants across the genome and PA in relation to CRC risk. Self-reported PA levels were categorized as active (≥ 8.75 MET-h/wk) vs. inactive (< 8.75 MET-h/wk) and as study- and sex-specific quartiles of activity. Results PA had an overall protective effect on CRC (OR [active vs. inactive] = 0.85; 95%CI = 0.81–0.90). The two-step GxE method identified an interaction between rs4779584, an intergenic variant near the GREM1 and SCG5 genes, and PA for CRC risk (p-interaction = 2.6×10 − 8 ). Stratification by genotype at this locus showed a significant reduction in CRC risk by 20% in active vs. inactive participants with the CC genotype (OR = 0.80; 95%CI = 0.75–0.85), but no significant PA–CRC association among CT or TT carriers. When PA was modeled as quartiles, the 1-d.f. GxE test identified that rs56906466, an intergenic variant near the KCNG1 gene, modified the association between PA and CRC (p-interaction = 3.5×10 − 8 ). Stratification at this locus showed that increase in PA (highest vs. lowest quartile) was associated with a lower CRC risk solely among TT carriers (OR = 0.77; 95%CI = 0.72–0.82). Conclusions In summary, we identified two genetic variants that modified the association between PA and CRC risk. One of them, related to GREM1 and SCG5 , suggests that the bone morphogenetic protein (BMP)-related, inflammatory, and/or insulin signaling pathways may be associated with the protective influence of PA on colorectal carcinogenesis.

Abstract The combination of enfortumab vedotin and pembrolizumab (EVP) has recently revolutionized care for patients with previously untreated locally advanced and metastatic urothelial carcinoma. However, predictive biomarkers of response, the optimal duration of EVP for patients who respond well to therapy, and the role of circulating tumor DNA to monitor treatment response have not yet been fully elucidated. In this molecular tumor board, we summarize 6 patients from 4 different academic institutions with unresectable or oligometastatic urothelial carcinoma who achieved long-term remission on surveillance after a short duration of EVP treatment that resulted in complete response on follow-up imaging followed by consolidative radical cystectomy. We discuss potential predictive biomarkers for patients with exceptional response to EVP. These findings highlight the need to determine an optimal duration of EVP to maximize efficacy while minimizing adverse events. We aim to further define and explore the value of local therapy with consolidative cystectomy in the setting of unresectable, locally advanced, oligometastatic disease, or those with metastatic disease who achieve complete response of disease outside of the bladder. Identifying this subset of patients who may be candidates for this type of multidisciplinary management may result in durable treatment-free remission.

BACKGROUND Approximately 10% of patients report penicillin allergy. Based on historical guidelines, patients with a penicillin allergy should receive an alternative to cephalexin for prophylaxis in dermatologic surgery. OBJECTIVE To determine, based on evidence, if cephalexin should be used as a first-line prophylactic antibiotic in dermatologic surgery for patients with penicillin allergy. METHODS Systematic review of the literature was performed with defined search terms. RESULTS Less than 5% of those with penicillin allergy labels have a true penicillin allergy. For patients with true, persistent penicillin allergy, there is an overall low cross-reactivity with cephalosporins, especially with cephalosporins that do not share identical R1 side chain. The first-generation cephalosporins, including cephalexin, have a slightly higher risk of cross-reactivity in patients with reported allergy to amino-penicillins (amoxicillin, ampicillin) but not other penicillins. The risk of severe cross-reactivity of cephalosporins in patients with low-risk penicillin allergies is extremely low. Cephalexin has a superior side effect profile and efficacy compared to alternatives. CONCLUSION Cephalexin should be used as the first-line prophylactic antibiotic in dermatologic surgery for patients with documented penicillin allergy, including anaphylaxis. There may be a higher risk of cross-reactivity with cephalexin in patients with a confirmed amino-penicillin allergy.

ABSTRACT Objective We sought to characterize patients presenting to emergency departments (EDs) with abdominal pain and to validate risk categories defined by the Guidelines for Reasonable and Appropriate Care in the Emergency Department (GRACE‐2) for low‐risk recurrent abdominal pain. Methods We conducted a retrospective cohort study of patients presenting with abdominal pain between November 2019 and November 2023 across 21 EDs in Arizona, the Midwest, and Florida. Patients were categorized per GRACE‐2 into recurrent and non‐recurrent pain as well as low‐ and high‐risk groups. Primary outcomes included 72‐h returns and mortality at 30 and 90 days. Results The study included 162,494 visits (112,896 unique patients; median age 46 years; 61.2% female). Among these, 4.3% had low‐risk recurrent abdominal pain. Patients with recurrent and non‐recurrent low‐risk pain had similar ED length of stay and discharge rates to each other, compared to patients with high‐risk pain who had longer length of stay and lower discharge rates. At 30 days after the ED encounter, patients with low‐risk recurrent abdominal pain had similar mortality to patients with low‐risk non‐recurrent pain (0.4% vs. 0.3%; adjusted RR = 1.31, 95% CI: 0.85–2.03), while they had significantly lower mortality than patients with high‐risk recurrent abdominal pain (0.4% vs. 2.3; adjusted RR = 3.14, 95% CI: 2.02–4.89). Conclusions This study highlights the heterogeneity in patients presenting to the ED with abdominal pain. Among these patients, those with low‐risk recurrent pain demonstrated similar lengths of stay, discharges, and mortality rates to those with low‐risk non‐recurrent pain and less favorable lengths of stay, discharges, and mortality rates compared to those with any high‐risk features. These findings suggest that low‐ and high‐risk features may be more useful than recurrent or non‐recurrent pain in identifying patients who could benefit from more robust ED evaluations.

The NCCN Guidelines for Thyroid Carcinoma address the management of different types of thyroid carcinoma, including papillary, follicular, oncocytic, medullary, and anaplastic carcinoma. The NCCN Thyroid Carcinoma Panel meets at least annually to review comments from reviewers within their institutions, examine relevant new data from publications and abstracts, and reevaluate and update their recommendations. These NCCN Guidelines Insights focus on the panel’s most recent recommendations regarding systemic therapies for thyroid carcinoma as well as the supporting clinical data.

Purpose To develop an expert consensus statement on the diagnosis, management, and rehabilitation of medial meniscal root tears (MMRTs) using a modified Delphi technique. Methods A working group developed statements on MMRT diagnosis, nonoperative management, surgical indications, surgical management, alignment, and rehabilitation using modified Delphi techniques. Fifty‐six experts were surveyed over 3 rounds to reach consensus, with agreement measured on a 5‐point Likert scale. Statements were included, revised, or excluded on the basis of predefined thresholds (≥75% agreement, <20% disagreement). Experts suggested revisions or new statements in the first 2 rounds, and final consensus statements were included. Results All 56 experts completed 3 survey rounds. Experts agreed that root tears may occur with no known history of trauma, typically in older patients, and that it should be diagnosed with an magnetic resonance imaging. In symptomatic patients with MMRTs without advanced osteoarthritis should be repaired using an anatomic transtibial pull‐out technique (performing a pie‐crusting technique can be helpful for visualization). Nonoperative management is advised for patients with advanced osteoarthritis. High tibial osteotomy may be considered for significant varus malalignment during MMRT repair. The only statement without consensus was the management of asymptomatic MMRTs with mild medial compartment cartilage wear, indicating ongoing debate. Conclusions Overall, 98% of statements reached consensus. There is agreement that magnetic resonance imaging is the gold standard for diagnosis. Symptomatic MMRTs without advanced osteoarthritis should be repaired early using an anatomic transtibial pull‐out technique. End‐stage knee osteoarthritis warrants nonoperative management of MMRTs, and a structured postoperative protocol with limited weightbearing and range of motion is essential after repair. No agreement was reached on managing asymptomatic MMRTs in patients without significant medial compartment degeneration. Meniscal centralization sutures may help in cases of substantial extrusion, but their routine use is debated. Level of Evidence Level V, consensus of expert opinion.
