Multivariable prognostic modelling to improve prediction of colorectal cancer recurrence: the PROSPeCT trial.

Objective: Improving prognostication to direct personalised therapy remains an unmet need. This study prospectively investigated promising CT, genetic, and immunohistochemical markers to improve the prediction of colorectal cancer recurrence.

Material And Methods: This multicentre trial (ISRCTN 95037515) recruited patients with primary colorectal cancer undergoing CT staging from 13 hospitals.

Hypertension Trends and Disparities Over 12 Years in a Large Health System: Leveraging the Electronic Health Records.

Background: The digital transformation of medical data enables health systems to leverage real-world data from electronic health records to gain actionable insights for improving hypertension care.

Methods And Results: We performed a serial cross-sectional analysis of outpatients of a large regional health system from 2010 to 2021. Hypertension was defined by systolic blood pressure ≥140 mm Hg, diastolic blood pressure ≥90 mm Hg, or recorded treatment with antihypertension medications.

Concentric Cardiac Remodeling and Hypertrophy in Pregnant Individuals with Chronic Hypertension.

Objective: This study aimed to evaluate rates of superimposed preeclampsia in pregnant individuals with echocardiography-diagnosed cardiac geometric changes in the setting of chronic hypertension.

Study Design: This was a retrospective study of pregnant individuals with chronic hypertension who delivered singleton pregnancies at 20 weeks' gestation or greater at a tertiary care center. Analyses were limited to individuals who had an echocardiogram during any trimester.

Sex Differences in Symptom Complexity and Door-to-Balloon Time in Patients With ST-Elevation Myocardial Infarction.

Greater symptom complexity in women than in men could slow acute ST-elevation myocardial infarction (STEMI) recognition and delay door-to-balloon (D2B) times. We sought to determine the sex differences in symptom complexity and their relation to D2B times in 1,677 young and older patients with STEMI using data from the VIRGO and SILVER-AMI studies. Symptom complexity was defined by the number of symptom patterns or phenotypes and average number of symptoms.

Diagnostic evaluation of upper tract urothelial carcinoma: can we safely omit diagnostic ureteroscopy?

Objective: To identify clinicopathological or radiological factors that may predict a diagnosis of upper urinary tract urothelial cell carcinoma (UTUC) to inform which patients can proceed directly to radical nephroureterectomy (RNU) without the delay for diagnostic ureteroscopy (URS).

Patients And Methods: All consecutive patients investigated for suspected UTUC in a high-volume UK centre between 2011 and 2017 were identified through retrospective analysis of surgical logbooks and a prospectively maintained pathology database. Details on clinical presentation, radiological findings, and URS/RNU histopathology results were evaluated.

The Role of the Electrocardiogram in Pregnant Individuals with Chronic Hypertension.

Objective: The American College of Obstetricians and Gynecologists suggests that an electrocardiogram is an acceptable first-line test. We sought to examine whether an electrocardiogram is a sufficient screening tool to identify echocardiogram-diagnosed left ventricular hypertrophy. We also sought to determine risk factors associated with left ventricular hypertrophy.

Diagnostic reasoning in cardiovascular medicine.

Research in cognitive psychology shows that expert clinicians make a medical diagnosis through a two step process of hypothesis generation and hypothesis testing. Experts generate a list of possible diagnoses quickly and intuitively, drawing on previous experience. Experts remember specific examples of various disease categories as exemplars, which enables rapid access to diagnostic possibilities and gives them an intuitive sense of the base rates of various diagnoses.

Sex Differences in Symptom Phenotypes Among Older Patients with Acute Myocardial Infarction.

Background: Clinicians make a medical diagnosis by recognizing diagnostic possibilities, often using memories of prior examples. These memories, called "exemplars," reflect specific symptom combinations in individual patients, yet most clinical studies report how symptoms aggregate in populations. We studied how symptoms of acute myocardial infarction combine in individuals as symptom phenotypes and how symptom phenotypes are distributed in women and men.

Conceptual Framework for Personal Recovery in Patients With Acute Myocardial Infarction.

Background Although there has been movement in cardiology to advance patient-centered approaches to postacute myocardial infarction (AMI) care, work remains to be done in aligning patient preferences with clinical care. Our objective was to characterize patients' experience of AMI and treatment to develop a new conceptual framework of patient-centered recovery in cardiology. Methods and Results We conducted in-depth interviews with people who previously experienced an AMI (2016-2019).

Assessment of Seroprevalence of SARS-CoV-2 and Risk Factors Associated With COVID-19 Infection Among Outpatients in Virginia.

Importance: Data from seroepidemiologic surveys measuring severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) exposure in diverse communities and ascertaining risk factors associated with infection are important to guide future prevention strategies.

Objective: To assess the prevalence of previous SARS-CoV-2 infection across Virginia and the risk factors associated with infection after the first wave of coronavirus disease 2019 (COVID-19) infections in the US.

Design, Setting, And Participants: In this statewide cross-sectional surveillance study, 4675 adult outpatients presenting for health care not associated with COVID-19 in Virginia between June 1 and August 14, 2020, were recruited to participate in a questionnaire and receive venipuncture to assess SARS-CoV-2 serology.

Empagliflozin Effects on Pulmonary Artery Pressure in Patients With Heart Failure: Results From the EMBRACE-HF Trial.

Background: Sodium glucose cotransporter 2 inhibitors (SGLT2 inhibitors) prevent heart failure (HF) hospitalizations in patients with type 2 diabetes and improve outcomes in those with HF and reduced ejection fraction, regardless of type 2 diabetes. Mechanisms of HF benefits remain unclear, and the effects of SGLT2 inhibitor on hemodynamics (filling pressures) are not known. The EMBRACE-HF trial (Empagliflozin Evaluation by Measuring Impact on Hemodynamics in Patients With Heart Failure) was designed to address this knowledge gap.

Maintenance of Competence in Cardiovascular Training and Practices: Worth the Effort?

Americans expect their doctors to have the competence to deliver high-quality care and expect safeguards to be in place that assure their doctors are competent. However, competence requires knowledge, and people have trouble assessing their own knowledge and level of competence. Because external assessment is required, several organizations have taken on the roles of defining and assuring medical competence.

Risk Model for Decline in Activities of Daily Living Among Older Adults Hospitalized With Acute Myocardial Infarction: The SILVER-AMI Study.

Background Functional decline (ie, a decrement in ability to perform everyday activities necessary to live independently) is common after acute myocardial infarction (AMI) and associated with poor long-term outcomes; yet, we do not have a tool to identify older AMI survivors at risk for this important patient-centered outcome. Methods and Results We used data from the prospective SILVER-AMI (Comprehensive Evaluation of Risk Factors in Older Patients With Acute Myocardial Infarction) study of 3041 patients with AMI, aged ≥75 years, recruited from 94 US hospitals. Participants were assessed during hospitalization and at 6 months to collect data on demographics, geriatric impairments, psychosocial factors, and activities of daily living.

Comorbid vision and cognitive impairments in older adults hospitalized for acute myocardial infarction.

Older patients presenting with acute myocardial infarction (AMI) often have comorbidities. Our objective was to examine how outcomes differ by cognitive and vision status in older AMI patients. We use data from a prospective cohort study conducted at 94 hospitals in the United States between January 2013 and October 2016 that enrolled men and women aged ≥75 years with AMI.

Sex Differences in Symptom Phenotypes Among Patients With Acute Myocardial Infarction.

Background: The diagnosis of acute myocardial infarction (AMI) is missed more frequently in young women than men, which may be related to the cognitive psychology of the diagnostic process. Physicians start the diagnostic process by intuitively recognizing familiar symptom phenotypes, but little is known about how symptoms combine in individuals as unique symptom phenotypes. We examined how symptoms of AMI combine as unique symptom phenotypes in individual patients to compare the distribution of symptom phenotypes in women versus men.

Effect of Teaching Bayesian Methods Using Learning by Concept vs Learning by Example on Medical Students' Ability to Estimate Probability of a Diagnosis: A Randomized Clinical Trial.

Importance: Clinicians use probability estimates to make a diagnosis. Teaching students to make more accurate probability estimates could improve the diagnostic process and, ultimately, the quality of medical care.

Objective: To test whether novice clinicians can be taught to make more accurate bayesian revisions of diagnostic probabilities using teaching methods that apply either explicit conceptual instruction or repeated examples.

Effect of Diabetes Mellitus on Complication Rates of Coronary Artery Bypass Grafting.

Previous studies have shown that diabetes mellitus (DM) is a risk factor for postoperative coronary artery bypass grafting (CABG) complications. More contemporary studies are needed to guide revascularization decisions in DM patients. We performed a single-center study of patients who underwent CABG.
