OBJECTIVE: To evaluate the performance of an internally developed and previously validated artificial intelligence (AI) algorithm for magnetic resonance (MR)-derived total kidney volume (TKV) in autosomal dominant polycystic kidney disease (ADPKD) when implemented in clinical practice. PATIENTS AND METHODS: The study included adult patients with ADPKD seen by a nephrologist at our institution between November 2019 and January 2021 and undergoing an MR imaging examination as part of standard clinical care...

OBJECTIVE: To describe the incidence, risk factors, and outcomes of incident atrial fibrillation (AF) in Graves disease (GD). PATIENTS AND METHODS: Patients with GD between January 1, 2009, and December 31, 2019, were included retrospectively. We defined GD-related AF as AF diagnosed less than or equal to 30 days before or any time after GD. Late-onset AF was defined as incident AF diagnosed more than 90 days after GD. RESULTS: Of 1371 patients with GD, AF occurred in 139 patients...

Magnesium disorders are common in clinical practice and when present can manifest clinically as cardiovascular, neuromuscular, or other organ dysfunction. Hypomagnesemia is far more common than hypermagnesemia, which is largely seen in patients with reduced glomerular filtration rates receiving magnesium-containing medications. In addition to inherited disorders of magnesium handling, hypomagnesemia is also seen with excessive gastrointestinal or renal losses and due to medications such as amphotericin B, aminoglycosides, and cisplatin...

Women at risk for hereditary breast and ovarian cancer syndromes are frequently seen in primary care and gynecology clinics. They present with a distinctive set of clinical and emotional needs that revolve around complex risk management discussions and decision making. The care of these women calls for the creation of individualized care plans that facilitate adjustment to the mental and physical changes associated with their choices. This article provides an update on comprehensive evidence-driven care of women with hereditary breast and ovarian cancer...

OBJECTIVE: To evaluate the association between serum urate and risk of incident chronic kidney disease (CKD) and to assess whether serum urate plays a causal role in CKD. PATIENTS AND METHODS: We conducted a prospective cohort study and Mendelian randomization analysis that analyzed longitudinal data from the Taiwan Biobank between January 1, 2012, and December 31, 2021. RESULTS: A total of 34,831 individuals met the inclusion criteria, of which 4697 (13...

OBJECTIVE: To determine the association between cervical nonorganic pain signs and epidural corticosteroid injection outcomes and coexisting pain and psychiatric conditions. PATIENTS AND METHODS: Seventy-eight patients with cervical radiculopathy who received epidural corticosteroid injection were observed to determine the effects that nonorganic signs have on treatment outcome. A positive outcome was a decrease of 2 or more points in average arm pain, coupled with a score of 5 on a 7-point Patient Global Impression of Change scale 4 weeks after treatment...

OBJECTIVE: To demonstrate early aging in patients with lamin A/C (LMNA) gene mutations after hypothesizing that they have a biological age older than chronological age, as such a finding impacts care. PATIENT AND METHODS: We applied a previously trained convolutional neural network model to predict biological age by electrocardiogram (ECG) [Artificial Intelligence (AI)-ECG age] to LMNA patients evaluated by multiple ECGs from January 1, 2003, to December 31, 2019...

OBJECTIVE: To study the relationship between the sex probability derived from the artificial intelligence (AI)-augmented electrocardiogram (ECG) and sex hormone levels. PATIENTS AND METHODS: Adult patients with total testosterone (TT; ng/dL) or estradiol (E2; pg/mL) levels (January 1, 2000, to December 31, 2020) with ECGs obtained within 6 months of the blood sample were identified. The closest ECG to the blood test was used. The AI-ECG model output ranges from 0...

Now, more than ever, digital technology has made its way into the daily lives of billions across the globe, and the widespread use of this technology has also allowed a digital window into consumers' and patients' daily lives, respectively. In a similar way, the practice of medicine has digitally evolved with the application of electronic health records and development of wearable/portable consumer-based medical devices (eg, Apple Watch ECG and Kardia Mobile by AliveCor). Alongside the increased use of digital technology in clinical care (eg, telehealth and wearable arrhythmia detection), clinical investigators have harnessed this powerful stockpile of data to gain insight into what happens to patients beyond the clinic walls...

OBJECTIVE: To determine differences in plasma sex hormone levels in male and female coronavirus disease 2019 (COVID-19) patients and healthy volunteers (HVs) because cell entry of severe acute respiratory syndrome coronavirus 2 occurs via the angiotensin-converting enzyme 2 receptor which is downregulated by 17β-estradiol. PATIENTS AND METHODS: Citrated plasma samples were collected from 101 patients with COVID-19 upon presentation to the emergency department and from 40 HVs between November 1, 2020, and May 30, 2021...

Recognizing the contribution art has had in the Mayo Clinic environment since the original Mayo Clinic Building was finished in 1914, Mayo Clinic Proceedings features some of the numerous works of art displayed throughout the buildings and grounds on Mayo Clinic campuses as interpreted by the author.
