BACKGROUND: Cytoreductive hepatectomy can improve survival and symptoms of hormonal excess in patients with small intestinal neuroendocrine tumor (siNET) liver metastases, but whether to proceed when peritoneal metastases are encountered at the time of planned cytoreductive hepatectomy is controversial. METHODS: This was a retrospective review of patients who underwent surgical management of metastatic siNETs at Mayo Clinic between 2000 and 2020. Patients who underwent cytoreductive operation for isolated liver metastases or both liver and peritoneal metastases were compared...

OBJECTIVE: To evaluate the completeness and reliability of recurrence data from an institutional cancer registry for patients with head and neck cancer. PATIENTS AND METHODS: Recurrence information was collected by radiation oncology and otolaryngology researchers. This was compared with the institutional cancer registry for continuous patients treated with radiation therapy for head and neck cancer at a tertiary cancer center. The sensitivity and specificity of institutional cancer registry data was calculated using manual review as the gold standard...

OBJECTIVE: To evaluate the association between trimethylamine N-oxide (TMAO) and related metabolites with adverse cardiovascular events in a multiethnic urban primary prevention population. METHODS: We performed a case-control study of 361 participants of the Dallas Heart Study, including 88 participants with an incident atherosclerotic cardiovascular disease (ASCVD) event and 273 controls matched for age, sex, and body mass index without an ASCVD event during 12 years of follow-up (January 1, 2000, through December 31, 2015)...

The number of individuals referred for coronary artery bypass grafting (CABG) with preoperative atrial fibrillation (AF) is reported to be 8% to 20%. Atrial fibrillation is a known marker of high-risk patients as it was repeatedly found to negatively influence survival. Therefore, when performing surgical revascularization, consideration should be given to the concomitant treatment of the arrhythmia, the clinical consequences of the arrhythmia itself, and the selection of adequate surgical techniques. This state-of-the-art review aimed to provide a comprehensive analysis of the current understanding of, advancements in, and optimal strategies for CABG in patients with underlying AF...

OBJECTIVE: To evaluate the association of carpal tunnel syndrome (CTS) with incident heart failure and incident amyloidosis and to assess the risk of CTS in pathogenic TTR genetic variant carriers. METHODS: This prospective cohort study included multiethnic US adults 18 years of age and older without prevalent heart failure and amyloidosis with available genotypic data from the All of Us Research Program. The primary outcomes were incident heart failure and incident amyloidosis...

OBJECTIVE: To evaluate mortality outcomes by varying degrees of reduced calf muscle pump (CMP) ejection fraction (EF). PATIENTS AND METHODS: Consecutive adult patients who underwent venous air plethysmography testing at the Mayo Clinic Gonda Vascular Laboratory (January 1, 2012, through December 31, 2022) were divided into groups based on CMP EF for the assessment of all-cause mortality. Other venous physiology included measures of valvular incompetence and clinical venous disease (CEAP [clinical presentation, etiology, anatomy, and pathophysiology] score)...

OBJECTIVE: To evaluate the association of 5 major cause-specific non-cardiovascular disease (CVD) and non-cancer deaths with cardiorespiratory fitness (CRF). METHODS: Patients were 36,645 men (43.3±9.3 years) free of known CVD and cancer at baseline who completed a maximal treadmill graded exercise test during a preventive examination at the Cooper Clinic (Dallas, Texas) between 1971 and 2003. CRF was quantified as maximal treadmill exercise test duration and grouped as low (referent), moderate, and high...

OBJECTIVE: To standardize international normalized ratio (INR) measurements and improve data integrity by enabling electronic result transmission for warfarin monitoring, two point-of-care (POC) devices were evaluated against an internal plasma INR reference method. METHODS: A multicenter study was pursued (January 24, 2022, through October 19, 2022) to compare concordance of two commercially available POC devices, Coag-Sense PT2 Meter (Coag-Sense) and CoaguChek XS Pro and Plus devices (CoaguChek), against an internal plasma INR method among patients treated with warfarin...

OBJECTIVE: To investigate the association between blood calcium concentration and incident kidney stone as well as to assess the role played by genetic susceptibility. METHODS: We performed a population-based cohort study based on participants from the UK Biobank. A multivariable Cox proportional hazards regression model was used to estimate hazard ratios (HRs) and 95% CIs of incident kidney stone for blood calcium level and polygenic risk score (PRS). In addition, the potential interaction was explored...

A visiting surgeon described his disappointment with an aspect of the Mayo Clinic in 1914, stating that there was "the almost lack of anything that could be dignified by the term 'lecture.'" One year later, the Mayo Foundation for Medical Education and Research was founded. By 1917, the foundation declared history of medicine a graduate-level subject, and history of medicine questions were included in final oral examinations. In 1920 and 1921, lectures were given on historical topics; however, these lectures petered out, and there were no historical lectures in the official curriculum of 1923 or 1924...

Ritlecitinib, an oral Janus kinase 3/tyrosine kinase expressed in hepatocellular carcinoma family inhibitor, was evaluated in patients with ulcerative colitis (UC) in a phase 2b trial. Model-informed drug development strategies were applied to bridge observations from phase 2b to predictions for a proposed phase 3 study design to assess the probability of achieving the target efficacy outcome. A longitudinal exposure-response model of the time course of the 4 Mayo subscores (rectal bleeding, stool frequency, physician's global assessment, and endoscopic subscore) in patients with UC receiving placebo or ritlecitinib was developed using population modeling approaches and an item response theory framework...

With the awareness that the Standard American Diet is a critical contributor to chronic diseases, this initiative aimed to assess the effects of a 28-day dietary challenge health care improvement project on health system employee energy level, sleep quality, gastrointestinal function, ability to concentrate, and aches/pains, including the impact of adherence level, during a period of restricted intake of gluten, dairy, and sugar offered annually from 2021 to 2023. A total of 754 employees completed the pre-challenge survey; analyses included 354 employees who completed both pre-challenge and post-challenge surveys in at least 1 year of this project...

OBJECTIVE: To determine associations of incident cancer diagnoses in women with recent emergency department (ED) care. PATIENTS AND METHODS: A retrospective cohort study analyzing biological females aged 18 years and older, who were diagnosed with an incident primary cancer (12 cancer types studied) from January 1, 2015, to December 31, 2021, from electronic health records. The primary outcome was a cancer diagnosis within 6 months of a preceding ED visit. Secondary outcomes included patient factors associated with a preceding ED visit...

OBJECTIVE: To investigate the association of incident use of diuretics with subsequent risk of incident bone fractures. PATIENTS AND METHODS: In a nationwide cohort of 863,339 US veterans receiving care from the VA health care system between October 1, 2004, and September 30, 2006, with follow-up through June 30, 2018, we examined the association of incident diuretic use (overall, and separately by thiazide, loop, and potassium-sparing diuretics) with subsequent risk of incident bone fractures using multivariable Cox regression models while minimizing confounding by indication using a target trial emulation approach...

OBJECTIVE: To evaluate the ability of routinely collected electronic health record (EHR) use measures to predict clinical work units at increased risk of burnout and potentially most in need of targeted interventions. METHODS: In this observational study of primary care physicians, we compiled clinical workload and EHR efficiency measures, then linked these measures to 2 years of well-being surveys (using the Stanford Professional Fulfillment Index) conducted from April 1, 2019, through October 16, 2020...

Art is integrated into the Mayo Clinic environment. Since the original Mayo Clinic Building was finished in 1914, many pieces have been donated or commissioned for patients and staff to enjoy. Each issue of Mayo Clinic Proceedings features a work of art (as interpreted by the author) that is displayed in a building or on the grounds of Mayo Clinic campuses.
