Background/Objectives: A 12-week trial demonstrated that phenotype-tailored lifestyle intervention (PLI) was associated with greater weight loss than standard lifestyle intervention (SLI); however, differences in dietary patterns between groups were not examined. Methods: This secondary analysis evaluated caloric and macronutrient intake at 12 weeks in adults with obesity (BMI ≥ 30 kg/m2), classified into four energy-balance phenotypes (abnormal satiation, reduced postprandial satiety, low energy expenditure, emotional eating) (n = 77) who underwent PLI or SLI. Dietary intake was assessed by 24-h recalls and verified by a blinded registered dietitian. Results: Groups were compared at 12 weeks adjusting for baseline values. PLI was associated with lower total energy intake than SLI (1273 ± 182 vs. 1894 ± 176 kcal/day; p = 0.018), due to lower carbohydrate (464 ± 76 vs. 818 ± 73 kcal/day; p = 0.002) and fat intake (479 ± 76 vs. 697 ± 73 kcal/day; p = 0.036); absolute protein intake did not differ. However, protein comprised a greater proportion of energy intake in PLI (26.8 ± 1.6%) than SLI (19.8 ± 1.5%; p = 0.003), and dairy protein contributed more to total energy in PLI (6.8 ± 0.8% vs. 3.7 ± 0.7%; p = 0.004). Conclusions: PLI was associated with lower energy intake, mainly due to reduced carbohydrate and fat intake, and a higher relative contribution of protein, consistent with phenotype-based recommendations rather than macronutrient prescriptions. These findings suggest a potential role for personalized dietary approaches in obesity management. However, the non-randomized design does not allow causal inferences.

Abstract Purpose To evaluate the association of long-term, continuous tirzepatide use with cardiometabolic risk parameters and estimated 10-year atherosclerotic cardiovascular disease (ASCVD) risk in real-world practice. Methods This multicenter retrospective observational study included 1,028 adults with overweight or obesity who received weekly subcutaneous tirzepatide for at least 12 months within the Mayo Clinic Health System from June 2022 through May 2024. ASCVD risk analyses included 275 individuals with complete baseline and 12-month follow-up data. Outcomes were changes in cardiometabolic parameters, estimated 10-year ASCVD risk, and ASCVD risk category. Results At 12 months, median total body weight loss (TBWL) was 12.6%. Fasting glucose, HbA1c, triglycerides, and alanine aminotransferase decreased by 19.5%, 16.0%, 8.5%, and 10.6%, respectively, whereas HDL cholesterol increased by 11.3% (all P < .001). Mean 10-year ASCVD risk did not change significantly overall (mean relative change, −3.7%; P = .18), but changes differed by TBWL category (ANOVA, P < .001). ASCVD risk decreased among individuals achieving 10%–20% TBWL (−9.6%; P = .009) and >20% TBWL (−14.2%; P = .005), but not among those achieving <10% TBWL (+7.7%; P = .22). Low-risk prevalence increased from 38.3% to 46.4% (P < .001), with 11.7% transitioning from higher-risk categories to low risk. Main findings Continuous tirzepatide use for at least 12 months was associated with clinically meaningful improvements in cardiometabolic parameters. Reductions in estimated 10-year ASCVD risk were observed among individuals achieving at least 10% TBWL, supporting greater weight loss as an important marker of cardiovascular risk improvement.

ABSTRACT Objective This study assessed the impact of sex and age on weight loss outcomes in patients receiving tirzepatide in real‐world clinical practice. Methods We conducted a retrospective cohort study of adults with overweight or obesity who initiated tirzepatide at Mayo Clinic between June 2022 and May 2024 and completed ≥ 12 months of continuous therapy. Primary outcome was total body weight loss percentage (TBWL%) at 15 months, stratified by sex and age groups (≤ 45, 46–59, ≥ 60 years). Results Among 1039 patients (57% women; mean age 56 ± 11 years), women achieved significantly greater TBWL% than men after 15 months of treatment (15.1% vs. 10.7%, p < 0.001). Patients aged ≤ 45 years had greater weight loss than those ≥ 60 years (15.1% vs. 12.3%, p = 0.024). In multivariable analyses, greater weight loss was independently associated with female sex, absence of type 2 diabetes, no prior obesity medication use, no concomitant weight gain‐promoting medications, and higher tirzepatide dosage. Age was not an independent predictor. Conclusions Sex, but not age, predicted weight loss with tirzepatide among individuals using the medication continuously for ≥ 12 months. These findings underscore the importance of incorporating sex‐specific considerations into personalized obesity treatment strategies.

Objective: To compare 1-year changes in estimated 10-year and lifetime atherosclerotic cardiovascular disease (ASCVD) risk following metabolic and bariatric surgery (MBS) versus glucagon-like peptide-1 receptor agonist (GLP-1RA) therapy among adults with obesity. Summary Background Data: Obesity is a major driver of ASCVD through adverse metabolic and inflammatory pathways. Metabolic and bariatric surgery and GLP-1 receptor agonists represent the most effective contemporary treatments for obesity and are increasingly used to mitigate cardiovascular risk. However, their comparative effects on integrated short-term and lifetime ASCVD risk in real-world clinical practice remain incompletely characterized. Methods: We conducted a retrospective cohort study of adults with obesity (body mass index ≥30 kg/m²) who underwent MBS or initiated GLP-1RA therapy between 2020 and 2023 within a large tertiary health care system in the United States. Participants were identified from electronic health records and followed for 12 months. Primary outcomes were 1-year changes in estimated 10-year and lifetime ASCVD risk. Secondary outcomes included percent total body weight loss, blood pressure, and lipid parameters. Multivariable linear regression models were used to adjust for baseline body mass index and baseline ASCVD risk. Results: The final cohort included 812 patients, of whom 579 underwent MBS and 233 initiated GLP-1RA therapy. At baseline, patients receiving GLP-1RAs were older and had higher estimated ASCVD risk. At 1 year, reductions in 10-year ASCVD risk were similar between groups (−0.8% vs. −1.1%; P =.36). In contrast, lifetime ASCVD risk decreased significantly more following MBS than GLP-1RA therapy (−8.6% vs. −1.7%; P <.001). MBS was associated with greater percent total body weight loss (−27.8% vs. −11.1%; P <.001) and more favorable lipid changes, including larger reductions in low-density lipoprotein cholesterol and greater increases in high-density lipoprotein cholesterol. After adjustment, MBS remained independently associated with a greater reduction in lifetime ASCVD risk compared with GLP-1RA therapy (β −6.92; 95% CI −9.22 to −4.62). Conclusions: In this real-world cohort, both MBS and GLP-1RA therapy were associated with improvements in estimated cardiovascular risk, but MBS conferred substantially greater reductions in lifetime ASCVD risk, accompanied by superior weight loss and lipid improvements. These findings highlight the complementary roles of surgical and pharmacologic therapies in obesity management and may inform strategies to optimize long-term cardiovascular risk reduction.

ABSTRACT Objectives While maxillary sinus fungal balls (MSFB) can be associated with odontogenic conditions (MSFBO), MSFBO clinical and dental features have not been compared to odontogenic sinusitis (ODS). This multicenter study aimed to compare characteristics of MSFB, MSFBO, and ODS. Methods A multicenter international retrospective cohort study was conducted on adults with MSFBs and ODS who underwent sinus surgery. First in MSFBs, it was determined whether different dental conditions were more likely in FB versus non‐FB sides. Second, clinical features and dental pathologies were compared between MSFBO and ODS. For analyses, dental conditions were considered individually and as two groups: infectious pathologies and dental/oral procedures with indwelling metallic materials. Results After exclusions, there were 203 MSFBs and 163 ODS. Among MSFBs, 141 were MSFBOs. FB sides were associated with sinus protrusion of root canal treatment (RCT) materials ( p = 0.040) and dental implants ( p = 0.040). Compared to MSFBO, ODS patients were younger, more likely to have MS purulence (OR = 40.9, p < 0.010), more likely associated with apical periodontitis (OR = 2.59, p = 0.010) and oroantral fistulas (OR = 6.94, p = 0.020), and less likely associated with extruded RCT materials (OR = 0.01, p = 0.010) and protruded midface screws (OR < 0.01, p = 0.010). Comparing purulent MSFBO and ODS, ODS was more associated with infectious dental pathologies ( p < 0.009). Conclusion Compared to MSFBs, MSFBOs were associated with RCT extrusion and implant protrusion. Compared to MSFBOs, ODS was more likely purulent and associated with infectious dental pathologies. While ODS is often distinct from MSFBO, the two conditions can coexist, and surgeons must determine whether patients have infectious dental pathology requiring treatment with both conditions. Level of Evidence 4.

Background/Objectives: Individuals with type 2 diabetes (T2D) achieve less total body weight loss (TBWL) with obesity medications compared to those without T2D. The individualized metabolic surgery (IMS) score, originally developed to predict T2D remission after bariatric surgery, inversely correlates with TBWL response to semaglutide. IMS reflects T2D severity, incorporating HbA1c and T2D duration and medication use. This study aims to evaluate TBWL with tirzepatide across IMS severity categories and identify predictors of response in a real-world cohort. Methods: This retrospective analysis included 717 adults with T2D using tirzepatide for overweight or obesity within the Mayo Clinic Health System. Patients were stratified by IMS severity (mild, moderate, severe) and quartiles. Primary endpoint: TBWL% at 15 months. Secondary endpoints: categorical thresholds (≥5%, ≥10%, ≥15%, ≥20%) and predictors of TBWL%. Linear mixed-effects models and regression models were employed. Results: At 15 months, TBWL was greater in mild versus severe IMS groups (14.8% vs. 11.0%, p = 0.015), with similar trends across quartiles. The proportion achieving ≥ 20% TBWL was nearly two-fold higher in mild versus severe IMS (27% vs. 14%, p = 0.03). Female sex independently predicted greater TBWL, whereas insulin use, higher T2D medication burden (particularly weight-promoting agents), and HbA1c > 7% were associated with less TBWL. Conclusions: Tirzepatide produced clinically meaningful TBWL across all IMS categories, although TBWL declined with increasing IMS severity. Glycemic control and T2D medication use emerged as strong predictors of TBWL. The IMS score may serve as a practical tool to anticipate weight-loss trajectories, guide personalized treatment decisions, and inform patient counseling.

Introduction: Tirzepatide, a dual GIP and GLP-1 receptor agonist, is an FDA-approved medication demonstrating the highest efficacy for weight loss among currently available treatments. However, the influence of sex and age on weight loss outcomes with tirzepatide remains unclear. Objective: To investigate the influence of sex and age on weight loss outcomes in patients treated with tirzepatide. Methods: This retrospective study evaluated weight loss outcomes associated with tirzepatide across sex and age groups. Patients with active malignancy, prior bariatric surgery, or concurrent anti-obesity medication were excluded. The primary endpoint was total body weight loss percentage (TBWL%) at 15 months by sex and age. The influence of age was analyzed as a categorical (≤45, 46-59, ≥60 years) and continuous variable. Secondary outcomes included TBWL% at 3, 6, 9, and 12 months by sex and age. Data were analyzed using independent t-tests, one-way ANOVA, and multivariate regression; results are reported as mean ± standard deviation. Results: The study included 1033 patients (57.1% female; mean age 56 ± 11 years; mean BMI, 37.7 ± 8 kg/m2). By age category, 18.8% (196) were ≤45 years (35.7% males, 64.3% females), 45.9% (473) were 46-59 years (42.7% males, 57.3% females), and 35.3% (364) were ≥60 years (54.7% males, 45.3% females). At all timepoints, TBWL was significantly greater in females compared to males at all timepoints. At 15 months females had a higher TBWL than males: 15.3% ± 10, n=340, vs. 10.2% ± 8, n=244, (p &lt; 0.001). Among females, premenopausal women achieved a higher TBWL than postmenopausal women: 16.9% ± 10 vs 14.4% ± 9, p = 0.04. Analysis by age groups revealed a trend toward higher TBWL in younger patients that did not reach statistical significance (p = 0.152): ≤45 years (14.7% ± 10%), 46-59 years (12.9% ± 10%), and ≥60 years (12.7% ± 9%). After adjusting for baseline age, BMI, and diabetes status, sex remained a strong predictor for weight loss outcomes (PE= 4.5, 95% CI [2.96, 5.97], p &lt; 0.001), following type 2 diabetes status (PE= 4.8, 95% CI [3.0, 6.7], p &lt; 0.001). Conclusion: Sex but not age was a strong predictor of weight loss with tirzepatide. Female sex was associated with greater weight loss than male sex. These results emphasize the importance of considering sex-specific factors in weight loss strategies and warrant further investigation into the underlying biological mechanisms. Differential weight loss by menopause, underscores the role of sex hormones. Presentation: Monday, July 14, 2025

M.D. Hurtado: Novo Nordisk, National Institute of Health, Phenomix Sciences. Background: Glucagon-like peptide-1 receptor agonists (GLP-1 RAs) have demonstrated cardiovascular (CV) benefits. Tirzepatide (TZP), a dual GLP-1 and gastric inhibitory polypeptide (GIP) receptor agonist approved for weight management and glycemic control, currently lacks evidence on CV outcomes. This study evaluates TZP’s impact on cardiometabolic parameters and atherosclerotic cardiovascular disease (ASCVD) risk scores. Methods: We conducted a multicenter retrospective study of adults prescribed TZP from June 1, 2022, to November 1, 2024. Inclusion criteria included 12 months of TZP use and age &gt;18 years. Exclusion criteria were pregnancy, active malignancy, concurrent FDA-approved antiobesity medications, and prior bariatric surgery. Endpoints included changes in blood pressure, lipid profiles, liver enzymes, glucose control parameters, medication use (statins, aspirin, antihypertensives), and ASCVD risk scores from baseline to 12 months, stratified by sex. Data were obtained from electronic medical records. We present data as mean differences [95% CI]. We used T-tests and multivariate regression analyses for analyses. Results: Among 831 participants (59.4% female; 91.2% White; mean age: 58 ± 12 years), 12-month weight loss was -12% [-13, -11], p&lt;0.001. We observed significant improvement in systolic blood pressure (SBP) (-4 [-5, -3] mmHg, p&lt;0.001), triglycerides (TG) (-38 [-52, -23] mg/dL, p&lt;0.001), total cholesterol (TC) (-7 [-10, -4] mg/dL, p&lt;0.001), LDL cholesterol (LDL) (-6 [-9, -4] mg/dL, p&lt;0.001), fasting glucose (FG) (-39 [-48, -29] mg/dL, p&lt;0.001), ALT (-10 [-15, -5] U/L, p&lt;0.001), HbA1c (-1.3% [-1.5, -1.2], p&lt;0.001), and HDL cholesterol (HDL) (+4 [+3, +5] mg/dL, p&lt;0.001). The Lifetime and 10-year ASCVD scores did not significantly change after 12 months (p&gt;0.05), underscoring TZP’s potential in mitigating the aging-associated increase in CV risk. Considering sex, females had greater weight loss (-13% [-14, -12] vs. -10% [-11, -9], p&lt;0.001), and greater improvements in TC (-5% [-8, -2] vs -3% [-6, 0.1], p&lt;0.001) and LDL (-10% [-14, -6] vs -4% [-8, 1], p&lt;0.001). Males had a greater reduction in DBP (-2% [-4, -1] vs (-1% [-6, 3], p=0.006). Both males and females demonstrated similar improvements in FG and HbA1c. Conclusion: TZP significantly improved CV and metabolic parameters after 12 months, with greater benefits observed in females. These improvements effectively mitigated the age-related rise in ASCVD risk scores. Larger, prospective studies are warranted to confirm these findings and further investigate TZP’s long-term CV effects. Presentation: Monday, July 14, 2025

Abstract Obesity is a chronic, heterogeneous, and complex disease associated with increased morbidity, mortality, and health-care costs. By 2030, 1 in 2 people in the United States will have obesity. Lifestyle interventions are the cornerstone of obesity management. However, they often fail to achieve clinically significant weight loss, necessitating additional treatments involving pharmacotherapy or procedures. Advancements in obesity pharmacotherapy have improved weight-loss outcomes and reduced associated comorbidities. Despite these advances, variability in response to treatment between individuals is still considerable. This variability reflects limitations in the current “one-size-fits-all” approach to obesity management. A precision medicine approach aims to address this gap by incorporating genetic, physiological, and behavioral characteristics to guide treatment selection and improve outcomes. Advances in multi-omics technologies, such as genomics, proteomics, metabolomics, and microbiome profiling, offer new opportunities to refine patient stratification and identify novel therapeutic targets. These tools may help move obesity care toward a more individualized and mechanism-based approach.
