The purpose of this commentary is to better inform physicians about the often-unrecognized consequences of cigarette smoking. It highlights knowledge gained from involvement in over 70 legal cases between smokers and cigarette companies in the Florida Engle Trials. As a physician with many years of experience in treating nicotine addiction, the author participated as a paid expert witness in these cases, 45 of which went to trial. Depositions included family members and close associates of the smoker, which allowed the gathering of voluminous information not usually available to a physician. This provided a level of insight into the suffering experienced that was illuminating. Based on this experience as an expert witness, 3 cases are presented that are clear examples of the tragedy experienced by smokers and their families. While not randomly selected, they are representative of the cases in which I participated. The impact of cigarettes on both smokers and those around them is difficult to quantify and is often not observable by healthcare professionals. The documented attitudes of cigarette lawyers, as seen in depositions and at trials, demonstrate an incredible lack of empathy and compassion. On the other hand, the cigarette companies are completely aware that almost 500 000 Americans die each year from use of their products, but death is only 1 outcome. What a sad commentary on the companies that knowingly perpetuated this epidemic and the lawyers who continue to defend them. Sadly, to both parties, it isn’t about the pain, suffering, morbidity, and death that these products cause. Rather, it is simply about money and staying in business on the one hand and money and winning on the other. However, the paramount lesson learned for all of us who take care of smoking patients is first to help them stop smoking and second to appreciate the wide-reaching ramifications of their tobacco dependence. Taking this empathic approach to their care will go a long way to demonstrating the compassion that is needed to provide a healing environment for the patient, their family, and loved ones.

Background: Artificial intelligence (AI) platforms can potentially enhance clinical decision-making (CDM) in primary care settings. OpenEvidence (OE), an AI tool, draws from trusted sources to generate evidence-based medicine (EBM) recommendations to address clinical questions. However, its effectiveness in real-world primary care cases remains unknown. Objective: To evaluate the performance of OE in providing EBM recommendations for five common chronic conditions in primary care: hypertension, hyperlipidemia, diabetes mellitus type 2, depression, and obesity. Methods: Five patient cases were retrospectively analyzed. Physicians posed specific clinical questions, and OE responses were evaluated on clarity, relevance, evidence support, impact on CDM, and overall satisfaction. Four independent physicians provided ratings using a 0 to 4 scale. Results: OE provided accurate, evidence-based recommendations in all cases, aligning with physician plans. OE was scored on a scale of zero to four, where zero was very unclear, and four was very clear. Mean scores across cases were clarity (3.55 ± 0.60), relevance (3.75 ± 0.44), support (3.35 ± 0.49), and satisfaction (3.60 ± 0.60). However, the impact on CDM was limited (1.95 ± 1.05), as OE primarily reinforced rather than modified plans. Conclusion: OE was rated high in clarity, relevance, and evidence-based support, reinforcing physician decisions in common chronic conditions. While the impact on CDM was minimal due to the study’s retrospective nature, OE shows promise in augmenting the primary care physician. Prospective trials are needed to evaluate its utility in complex cases and multidisciplinary settings.

Objective: Multicancer Detection (MCD) tests, such as the GRAIL Galleri, offer a novel approach to cancer screening by detecting cancer-specific methylation patterns in cell-free DNA through a single blood sample. This study evaluated an 18-month implementation of MCD testing in a tertiary ambulatory internal medicine clinic. Patients and Methods: Between June 2022 and November 2023, 2244 asymptomatic (without symptoms attributed to cancer) patients underwent MCD testing. The study focused on operational workflows, patient and physician education, and diagnostic follow-up of positive results. Standardized materials, including electronic health record (EHR) workflows, FAQs, and diagnostic pathways, were developed to facilitate implementation. Challenges included managing false positives, patient anxiety, costs, and ethical considerations. Results: Of the 2244 patients tested, 17 (0.76%) had positive results, and 15 underwent further diagnostic evaluation. Cancer was confirmed in 11 (73.3%) patients, including cases of breast, colon, esophageal, lymphoma, ovarian, and pancreatic cancers. Four patients had no identifiable malignancy despite comprehensive work-up. Conclusions: MCD testing is feasible in routine clinical workflows, with 73% of positive cases yielding cancer diagnoses. While promising, further research is required to assess long-term outcomes, cost-effectiveness, and optimal implementation strategies of cancer interception in broader healthcare settings.

Introduction: The Undiagnosed Mass Clinic (UMC) at our institution is a clinical and research program created to address gaps in the early diagnostic phase of the cancer care continuum for patients with potential malignant neoplasms. All patients referred to the UMC are invited to participate in the UMC registry, which tracks operational and clinical metrics while maintaining a repository of blood and tissue specimens for future research. Methods: We conducted a retrospective cohort study of the first 100 patients enrolled in the UMC registry. We analyzed patient demographics, final diagnoses, and the time from initial consultation to final diagnosis. Results: Most participants were White (86%), non-Hispanic (93%), and married (72%). The mean (SD) age was 64 (13.9) years. The final diagnoses of the masses were categorized as malignant/neoplastic with malignant potential (n = 53), benign (n = 36), or requiring diagnostic surveillance (n = 10). The mean (SD) time from initial consultation to final diagnosis of malignant/neoplastic with malignant potential masses significantly improved from 37.4 (36.6) days for the first 50 participants to 17.3 (19.7) days for the next 50 participants ( P = .006). Conclusions: These initial insights from the UMC registry will help direct future efforts to improve the care of patients with potential malignant neoplasms.

Objective: This study evaluated the feasibility and satisfaction of using a wearable brain activity sensing device for stress reduction among patients experiencing Long COVID (LC). Patients and Methods: Patients with LC (N = 45) were invited to participate in an open-label pilot study. Participants were asked to use a brain-sensing electroencephalogram (S-EEG) wearable device (Muse-S™) daily for 90 days and followed for an additional 90 days (180 days total participation). Study enrollment began June 28, 2022, and ended July 28, 2023. Results: Patients were predominantly female (82%), white (96%), and with an average age of 47.6 (±12.5) years. At the end of treatment (90 days), cognition, sleep, self-efficacy, and quality-of-life quality of life improved ( P < .001 to P = .04). In addition, stress and anxiety were significantly reduced ( P < .001). These significant changes persisted by end-of-study (180 days). For stress ( P = .023) and anxiety ( P = .033), a change from the baseline during follow-up was significantly associated with the amount of S-EEG usage. The end-of-study satisfaction survey indicated that patients were very satisfied with the S-EEG device, and 97% planned to continue using it. Conclusion: Results suggest that the S-EEG device improved cognition in LC, which is one of the main severe symptoms we see in our LC clinic. In addition, it helped reduce stress and anxiety. These findings have important clinical implications for LC patients using S-EEG as an adjunct to concurrent LC clinical care which includes pharmacotherapies.

A 67-year-old male with positive signals for neuroendocrine and head/neck cancer on a commercially available multicancer detection test underwent an extensive negative diagnostic workup at a local hospital. Referred to our medical center for advanced imaging and endoscopic procedures ultimately led to the diagnosis of an early-stage seminoma with eventual orchiectomy. This case highlights challenges in evaluating positive multicancer detection results, emphasizing the need for a broader understanding of how to interpret these testing results to fully evaluate complex cases, as well as the need for protocolized follow-up approaches to a positive multicancer detection test.

Purpose of review Once considered to have only local influences on the gut mucosa, short-chain fatty acids (SCFAs) now appear to have a much wider anti-inflammatory, immune-modulating, systemic effect. This article reviews recent evidence to suggest a much wider clinical application of this valued dietary substrate. Recent findings SCFAs act systemically through stimulation of G protein receptors (GPRs) and inhibition of histone deacetylases (HDACs). SCFAs cause appetite suppression, reduce systemic inflammation, improve insulin sensitivity, increase energy expenditure, promote mitochondrial function, stimulate satiety, reduce blood pressure, and improve cognitive function from various neurologic maladies. Summary Dietary strategies should be implemented to provide this beneficial substrate across a wide spectrum of disease conditions. Use of prebiotic fiber or liquid supplements containing high SCFA-producing organisms should be considered as therapeutic targets for multiple metabolic, immunologic, and neurodegenerative diseases.

Objectives: To identify patient characteristics, health concerns, and barriers to care based on overweight or obesity. Methods: A 50-question anonymous survey was administered to patients. Data were compared by body mass index (BMI). Results: Among 3976 distributed surveys, 899 were returned and 682 were analyzed. Most respondents were women (60%), White (94%), and married/partnered (65%) and had some college education (80%). Younger and unmarried persons had higher BMI ( P < .001). Concern for quality of life ( P < .001) and importance of lifestyle changes ( P = .006) increased with BMI, but confidence in making changes decreased as BMI increased ( P < .001). Perceived good health decreased with increasing BMI ( P < .001), whereas depression and other comorbid conditions increased. Self-esteem decreased and stigma increased with higher BMI (both P < .001). Weight discussions with clinicians ( P < .001) and belief that clinicians should be involved in weight management ( P = .002) increased with BMI, yet self-perception of being judged by clinicians also increased ( P < .001). As BMI increased, delays in seeking health care increased ( P < .001). Conclusions: This survey study highlights perceived health concerns and barriers to care among persons with overweight and obesity. With higher BMI, self-esteem decreased, and stigma, self-perception of poor health, perception of being judged by clinicians, and delay in seeking medical care increased.

BACKGROUND: Patients with heart failure with preserved ejection fraction and obesity have significant disability and frequent exacerbations of heart failure. We hypothesized that tirzepatide, a long-acting agonist of glucose-dependent insulinotropic polypeptide and glucagon-like peptide-1 receptors, would improve a comprehensive suite of clinical end points, including measures of health status, functional capacity, quality of life, exercise tolerance, patient well-being, and medication burden, in these patients. METHODS: We randomized (double-blind) 731 patients with class II to IV heart failure, ejection fraction ≥50%, and body mass index ≥30 kg/m 2 to tirzepatide (titrated up to 15 mg SC weekly; n=364) or placebo (n=367) added to background therapy for a median of 104 weeks (quartile 1, 66; quartile 3, 126 weeks). The primary end points were whether tirzepatide reduced the combined risk of cardiovascular death or worsening heart failure and improved Kansas City Cardiomyopathy Questionnaire Clinical Summary Score. The current expanded analysis included sensitivity analyses of the primary end points, 6-minute walk distance, EQ-5D-5L health state index, Patient Global Impression of Severity Overall Health score, New York Heart Association class, use of heart failure medications, and a hierarchical composite based on all-cause death, worsening heart failure, and 52-week changes in Kansas City Cardiomyopathy Questionnaire Clinical Summary Score and 6-minute walk distance. RESULTS: Patients were 65.2±10.7 years of age; 53.8% (n=393) were female; body mass index was 38.2±6.7 kg/m 2 ; Kansas City Cardiomyopathy Questionnaire Clinical Summary Score was 53.5±18.5; 6-minute walk distance was 302.8±81.7 m; and 53% (n=388) had a worsening heart failure event in the previous 12 months. Compared with placebo, tirzepatide produced a consistent beneficial effect across all composites of death and worsening heart failure events, analyzed as time to first event (hazard ratios, 0.41–0.67). At 52 weeks, tirzepatide increased the Kansas City Cardiomyopathy Questionnaire Clinical Summary Score by 6.9 points (95% CI, 3.3–10.6; P <0.001), 6-minute walk distance 18.3 meters (95% CI, 9.9–26.7; P <0.001), and EQ-5D-5L 0.06 (95% CI, 0.03–0.09; P <0.001). The tirzepatide group shifted to a more favorable Patient Global Impression of Severity Overall Health score (proportional odds ratio, 1.99 [95% CI, 1.44–2.76]) and New York Heart Association class (proportional odds ratio, 2.26 [95% CI, 1.54–3.31]; both P <0.001) and required fewer heart failure medications ( P =0.015). The broad spectrum of effects was reflected in benefits on the hierarchical composite (win ratio, 1.63 [95% CI, 1.17–2.28]; P =0.004). CONCLUSIONS: Tirzepatide produced a comprehensive, meaningful improvement in heart failure across multiple complementary domains; enhanced health status, quality of life, functional capacity, exercise tolerance, and well-being; and reduced symptoms and medication burden in patients with heart failure with preserved ejection fraction and obesity.
