Frailty and cardiovascular mortality in more than 3 million US Veterans.

AIMS: Frailty is associated with an increased risk of all-cause mortality and cardiovascular (CV) events. Limited data exist from the modern era of CV prevention on the relationship between frailty and CV mortality. We hypothesized that frailty is associated with an increased risk of CV mortality. METHODS AND RESULTS: All US Veterans aged ≥65 years who were regular users of Veteran Affairs care from 2002 to 2017 were included. Frailty was defined using a 31-item previously validated frailty index, ranging from 0 to 1. The primary outcome was CV mortality with secondary analyses examining the relationship between frailty and CV events (myocardial infarction, stroke, revascularization). Survival analysis models were adjusted for age, sex, ethnicity, geographic region, smoking, hyperlipidaemia, statin use, and blood pressure medication use. There were 3 068 439 US Veterans included in the analysis. Mean age was 74.1 ± 5.8 years in 2002, 76.0 ± 8.3 years in 2014, 98% male, and 87.5% White. In 2002, the median (interquartile range) frailty score was 0.16 (0.10-0.23). This increased and stabilized to 0.19 (0.10-0.32) for 2006-14. The presence of frailty was associated with an increased risk of CV mortality at every stage of frailty. Frailty was associated with an increased risk of myocardial infarction and stroke, but not revascularization. CONCLUSION: In this population, both the presence and severity of frailty are tightly correlated with CV death, independent of underlying CV disease. This study is the largest and most contemporary evaluation of the relationship between frailty and CV mortality to date. Further work is needed to understand how this risk can be diminished. KEY QUESTION: Can an electronic frailty index identify adults aged 65 and older who are at risk of CV mortality and major CV events? KEY FINDING: Among 3 068 439 US Veterans aged 65 and older, frailty was associated with an increased risk of CV mortality at every level of frailty. Frailty was also associated with an increased risk of myocardial infarction and stroke, but not revascularization. TAKE HOME MESSAGE: Both the presence and severity of frailty are associated with CV mortality and major CV events, independent of underlying CV disease.

Development and utilization of a web-based application as a robust radiology teaching tool (radstax) for medical student anatomy teaching.

Rationale and Objectives: The primary role of radiology in the preclinical setting is the use of imaging to improve students' understanding of anatomy. Many currently available Web-based anatomy programs include either suboptimal or overwhelming levels of detail for medical students.Our objective was to develop a user-friendly software program that anatomy instructors can completely tailor to match the desired level of detail for their curriculum, meets the unique needs of the first- and the second-year medical students, and is compatible with most Internet browsers and tablets.Materials and Methods: RadStax is a Web-based application developed using free, open-source, ubiquitous software. RadStax was first introduced as an interactive resource for independent study and later incorporated into lectures. First- and second-year medical students were surveyed for quantitative feedback regarding their experience.Results: RadStax was successfully introduced into our medical school curriculum. It allows the creation of learning modules with labeled multiplanar (MPR) image sets, basic anatomic information, and a self-assessment feature. The program received overwhelmingly positive feedback from students. Of 115 students surveyed, 87.0% found it highly effective as a study tool and 85.2% reported high user satisfaction with the program.Conclusions: RadStax is a novel application for instructors wishing to create an atlas of labeled MPR radiologic studies tailored to meet the specific needs their curriculum. Simple and focused, it provides an interactive experience for students similar to the practice of radiologists.This program is a robust anatomy teaching tool that effectively aids in educating the preclinical medical student.

No patients to resect or transplant: an analysis of patients with hepatocellular carcinoma admitted to a major African referral hospital.

BACKGROUND: This study aimed to describe the characteristics of patients diagnosed with hepatocellular carcinoma (HCC) at the Komfo Anokye Teaching Hospital (KATH) in Ghana and to determine their treatment options per the Barcelona Clinic Liver Cancer (BCLC) algorithm. METHODS: We reviewed the medical records of patients diagnosed with HCC at KATH in the period 2007-2013. Patient demographics, medical history, investigations, management, and outcome were extracted. BCLC staging was applied to determine their treatment options. Results were expressed as descriptive statistics. RESULTS: The charts for 206/465 patients were available for review. The male:female ratio was 2:1 and mean age was 44.0 ± 14.5 years. Common presenting complaints were abdominal distension, abdominal pain, and jaundice. hepatitis B virus (HBV) positivity was 52 %. Almost all patients received only supportive treatment. None underwent surgery, ablation, or transarterial chemoembolization. BCLC staging could be completed for 118 patients. Using predicted INR values in cases without the result, < 8 % of patients were eligible for resection, transplantation, or ablation; 25-53 % were eligible for embolization or sorafenib therapy. Up to 72 % were eligible only for supportive care. Seventy-six percent of patients reviewed were discharged alive; 71 % of patients whose charts were not available died during an admission. Thus, of the 465-patient cohort, 50 % died in the hospital. CONCLUSIONS: The majority of HCC in our population is caused by HBV. Up to 61 % of patients may be eligible for curative treatment, transarterial chemoembolization, or sorafenib treatment. This percentage may be increased with a robust surveillance program for patients at increased risk for HCC. Hepatitis B vaccination must also be a public health priority.
