Abstract Background Recommended noninvasive strategies for average-risk colorectal cancer (CRC) screening include multitarget stool DNA and fecal immunochemical test from ages 45 to 75 years. With new clinical trials, performance data for next-generation multitarget stool DNA, multitarget stool RNA, and blood-based screening tests are now available. This decision analytical model study evaluated the estimated benefit-to-burden ratio by means of efficient frontiers for noninvasive established and emerging CRC screening strategies. Methods Outcomes were estimated using the Colorectal Cancer and Adenoma Incidence and Mortality microsimulation model for average-risk individuals in the United States. Screening strategies were next-generation multitarget stool DNA (an updated marker panel), fecal immunochemical tests, multitarget stool RNA, or blood-based tests every 1-3 years, over various age ranges. Test performance inputs were derived from recent large clinical trials. A strategy was deemed efficient if no other strategy provided more life-years gained with equivalent or fewer lifetime colonoscopies and near-efficient if within 3 days of life-years gained of the efficient frontier. Results All modeled screening strategies resulted in life-years gained vs no screening. No strategy using blood-based tests was efficient or near-efficient. Overall, 10 strategies were efficient (6 next-generation multitarget stool DNA and 4 fecal immunochemical tests), including 2 strategies among those ages 45-75 years (biennial and triennial next-generation multitarget stool DNA). Overall, 22 strategies were near-efficient, including 4 strategies among those ages 45-75 years (annual, biennial, or triennial fecal immunochemical test; annual next-generation multitarget stool DNA). Conclusion Based on this modeling study, next-generation multitarget stool DNA was the only noninvasive screening test at guideline-endorsed interval and age-recommended ranges that was deemed efficient. Blood-based and multitarget stool RNA strategies were deemed not efficient for primary screening.

ABSTRACT Objectives Patients requiring long‐term enteral nutrition or continuous infusion of carbidopa/levodopa can benefit from jejunostomy tube placement. Recently, directly placed percutaneous transgastric jejunal tubes (TGJs) have been used instead of gastrostomy tubes with jejunal extensions (PEG‐Js) for enteral access. We aim to compare patient characteristics and outcomes after placement of TGJs placed via the introducer technique compared to PEG‐Js. Methods We performed a retrospective study of 141 patients (TGJ = 58, PEG‐J = 83) assessed at Mayo Clinic between 2010 and 2024. Patients were identified using a prospectively maintained procedure data registry. Demographic data, patient characteristics, procedural indications, complications, and first‐replacement date were gathered. Statistical analysis included the Wilcoxon rank sum test, chi‐square test, Fisher's exact test, and Kaplan‐Meier estimates. Patients receiving carbidopa/levodopa were excluded from complications analysis due to the carbidopa/levodopa tube's proprietary structure. A p ‐value of <0.05 was set as a threshold for significance. Results Our results demonstrated no difference in cumulative incidence of complications within 1 year for TGJs and PEG‐Js, p ‐value 0.48. Regarding time to first replacement, treating death as a competing risk factor, there was no statistically significant difference in cumulative incidence of replacement within 1 year for TGJs and PEG‐Js, p ‐value 0.389. Conclusions Our study demonstrates that both direct TGJs and PEG‐Js are safe options for long‐term jejunal feeding. More studies are needed to compare endoscopic to radiologically placed percutaneous transgastric jejunal feeding tubes.

Abstract Dobbs, WC, Almonroeder, TG, Carpenter, M, Schmitt, RE, Jacobson, AK, Luedke, JA, Roberts, BM, and Jagim, AR. Relationships between the Army Combat Fitness Test scoring structure and laboratory measurements of physical fitness in reserve officer training corps cadets. J Strength Cond Res 39(7): 798–808, 2025—The Army Combat Fitness Test (ACFT) assesses aerobic and anaerobic fitness capabilities in the U.S. Army. The aim of this study was to evaluate the association between raw and composite ACFT scores and laboratory-based measurements of fitness. Nineteen Reserve Officers' Training Corp cadets performed a battery of laboratory-based fitness testing. Tests included a movement screening (Fusionetics), countermovement jumps, and maximal isometric mid-thigh pulls on portable force plates to determine power and strength. A Wingate test involving maximal cycling for 30 seconds was used to determine peak and mean power. On a separate day, cadets completed body composition and a graded exercise test on a motorized treadmill to determine peak oxygen uptake (V̇ o 2 peak). Pearson correlations and partial corrections with 2000 bootstraps were used to compare ACFT scores (raw, composite, gender-neutral composite, and z -scores) with laboratory results. Significant associations were identified as 95% confidence intervals, not including zero. The results indicated that V̇ o 2 peak ( r = 0.61, [0.08–0.84]), body fat percentage ( r = −0.4, [−0.72 to −0.06]), and relative peak power ( r = 0.38, [0.02–0.68]) were associated with the total ACFT composite score when partialled by sex. All laboratory tests, except the movement screening, showed meaningful associations with total ACFT z -scores and gender-neutral ACFT scores ( r > 0.54). However, most relationships were eliminated when partialled out by sex, which may be due to a low sample size of women. This suggests the current scoring structure utilized for men is representative of aerobic and anaerobic fitness parameters and may be able to discriminate performance levels.

Background: Lithium is a mainstay treatment for bipolar disorder, but its narrow therapeutic index and susceptibility to pharmacokinetic interactions make appropriate monitoring crucial. Glucagon-like peptide-1 receptor agonists (GLP-1 RAs), such as semaglutide, are increasingly prescribed for type 2 diabetes and weight management. Scarce evidence exists on the potential interaction between semaglutide and lithium. Methods: We present 3 cases involving patients on stable lithium regimens who were initiated on semaglutide, reviewing potential mechanisms underlying the interaction between them. Findings: In 2 cases, lithium levels increased significantly, leading to toxicity despite stable renal function and no changes in concurrent medications. In the third case, preemptive reductions in lithium dosage mitigated toxicity, although lithium levels remained higher than anticipated. Mechanistic hypotheses that might contribute to semaglutide-associated elevated lithium levels include altered kidney function, dehydration from reduced oral intake, vomiting, or diarrhea, and delayed gastric emptying. Conclusions: To our knowledge, this is one of the first documented case series describing a potential interaction between semaglutide and lithium in the medical literature. These cases underscore the importance of vigilant monitoring when combining lithium with semaglutide, and potentially other GLP-1 RAs. Baseline renal function, hydration status, and lithium levels should be assessed before initiating semaglutide, and lithium levels should be monitored more frequently during therapy. Clinicians prescribing semaglutide to patients on lithium should exercise caution, monitor for signs of toxicity, and provide appropriate patient education. Further research is needed to elucidate the mechanisms of this potential interaction and its clinical significance.

Abstract Diffuse large B-cell lymphoma (DLBCL) poses a challenge in hematology given its varied symptoms, and the complex interplay between disease and treatment effects on health-related quality of life (HRQoL). The phase 3 POLARIX study demonstrated superior progression-free survival and a similar safety profile with polatuzumab vedotin plus rituximab, cyclophosphamide, doxorubicin, and prednisone (Pola-R-CHP) vs R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone) in patients with previously untreated DLBCL. Here, we evaluate HRQoL through patient-reported outcome (PRO) instruments to fully characterize the patient experience in the POLARIX study. Changes from baseline in HRQoL, lymphoma symptoms, and gastrointestinal (GI) symptoms were assessed, as well as incidence and severity of common symptoms by PROs vs clinician-reported adverse events (AEs). Baseline characteristics of PRO-evaluable patients (N = 874) were consistent. Comparison between PROs and clinician-reported AEs revealed a notable discordance; patients generally reported a higher incidence of symptoms than clinicians, emphasizing the need for patient-centric tools to accurately capture the patient experience. Both treatments exhibited rapid and sustained improvements in HRQoL and lymphoma symptoms, with the most substantial improvements seen in global health status/QoL, lymphoma symptoms, fatigue, role, emotional, and social functioning. GI symptoms (diarrhea, constipation, nausea, and vomiting) were generally similar between treatment arms and returned to baseline levels after treatment completion. These HRQoL data underscore the complementarity of PROs, as an adjunct to clinician-reported AEs, in evaluating the efficacy and tolerability of new treatments, including Pola-R-CHP, which may represent a new benchmark for patient-reported HRQoL in previously untreated DLBCL. This trial was registered at www.clinicaltrials.gov as NCT03274492.
