Physical activity led to lower risk of CV events – regardless of genetic risk
Exercise might help compensate for a high genetic risk of cardiovascular disease, according to the findings of a large prospective observational cohort study.
High-risk individuals in the top cardiorespiratory fitness tertile had a 49% lower risk of coronary heart disease (hazard ratio, 0.51; 95% confidence interval, 0.38-0.69) and a 60% lower risk of atrial fibrillation (HR, 0.40; 95% CI, 0.30-0.55) compared with those in the bottom fitness tertile, reported Emmi Tikkanen, PhD, of Stanford (Calif.) University, and her associates. The study was published in Circulation.
Little is known about whether exercise offsets genetic risk for cardiovascular disease. For the study, the researchers measured grip strength, cardiorespiratory fitness (based on net oxygen consumption while riding a stationary bicycle), cardiovascular events, and mortality among 482,702 participants in the UK Biobank longitudinal cohort study. More than half of individuals were women and none had baseline evidence of heart disease. The researchers stratified cases of coronary artery disease (CHD) and atrial fibrillation (AF) by whether individuals were at high, intermediate, or low genetic risk based on genome-wide association data.
Over a median follow-up period of 6.1 years (interquartile range, 5.4 to 6.8 years), there were nearly 21,000 cardiovascular events, including more than 8,000 cases of CHD and nearly 10,000 cases of AF. For all risk groups, increased grip strength and cardiorespiratory fitness were associated with a significantly lower risk of CHD and AF (P less than .001), even after adjustment for demographic factors, diabetes, smoking, systolic blood pressure, body mass index, and use of lipid-lowering medications.
The researchers did not look closely at types or durations of exercise. “Future studies evaluating the effects of strength versus aerobic training on subclinical or clinical cardiovascular outcomes could help to tailor exercise programs for individuals with elevated genetic risk for these diseases,” they wrote.

Team maps genetic evolution of T-ALL subtype
Single-cell analysis has revealed key genetic events in a type of T-cell acute lymphoblastic leukemia (T-ALL), according to researchers.
The team tracked the branching pattern of evolution in STIL-TAL1-positive T-ALL and identified mutations that may trigger development of the disease.
The researchers believe their findings could be used in minimal residual disease assessments as well as for the development of new targeted drugs.
Caroline Furness, MD, of Institute of Cancer Research in London, UK, and her colleagues described this research in Leukemia.
To determine the sequence of mutational events in STIL-TAL1-positive T-ALL, the researchers examined individual leukemia cells from 19 children and young adults with the disease, as well as 1 cell line with the STIL-TAL1 rearrangement (RPMI 8402).
The team found the STIL-TAL1 gene fusion and inactivation of the CDKN2A gene occurred very early in leukemia development.
The researchers said it was difficult to tell whether STIL-TAL1 fusion or CDKN2A loss are initiating events in this disease, and it isn’t clear which mutational event occurs first.
However, the team believes the STIL-TAL1 fusion is likely a founder or truncal event for this type of leukemia, so targeting the TAL1 regulatory complex could be an effective way to treat the disease.
The researchers also identified mutations in NOTCH1 and PTEN as secondary subclonal events.
Half of the samples examined had errors affecting PTEN, which suggests these events are key to maintaining leukemia growth and survival in STIL-TAL1-positive T-ALL, according to the researchers.
“We need to understand how cancers evolve and unpick which mutations are key to triggering cancer development and which are important for driving its growth and spread,” Dr Furness said.
“Our study uncovered these crucial mutations in a type of leukemia that accounts for around a quarter of cases of T-cell leukemia in children and young adults. This will help us to develop more effective treatments, especially in those children who relapse, and kinder treatments that won’t cause life-long side effects.”

Language difficulties persist until age 13 for very preterm infants
Children born very preterm continue to display language difficulties compared with term controls at 13 years of age, with no evidence of developmental “catch up.”
Given the functional implications associated with language deficits, early language-based interventions should be considered for children born VP, investigators wrote in Pediatrics.
“Difficulties in language functioning in this cohort of children born VP remained stable from 2 to 13 years of age. Although generalized language deficits were observed, the VP group had marked difficulties on expressive components of language,” wrote Thi-Nhu-Ngoc Nguyen, BSc, of Monash University, Melbourne, and her associates.

ANSWER
The radiograph demonstrates no acute injury to the wrist. There is, however, a subtle nondisplaced fracture of the distal fifth metacarpal joint. The patient was given a wrist splint for symptomatic relief, and orthopedic follow-up was coordinated.
A 31-year-old man is brought to your facility by local law enforcement for evaluation of left wrist pain following an altercation. The patient was reportedly at a local bar; as he was leaving, he started arguing with some other patrons. A fight ensued.
The patient believes he was struck by something on his left wrist. He denies any other injuries or complaints. His medical history is unremarkable, and vital signs are stable.
Physical examination of his left wrist shows no obvious deformity. There is some mild swelling over the dorsal aspect of his wrist. Range of motion is painful and limited. Good capillary refill is noted in the fingers, and sensation is intact. Good pulses are present.
Radiograph of the left wrist is obtained. What is your impression?
Use of a risk score may be able to identify high-risk patients presenting with acute heart failure
Clinical question: Can we use readily available data to risk stratify patients who present to the emergency department in acute heart failure (AHF)?
Background: Although cardiac biomarkers such as troponin and B-natriuretic peptide have general prognostic value in patients with AHF presenting to the emergency department, these values do not reliably aid in determining patients’ risk for unfavorable outcomes at the time of clinical decision making. Currently available published scores for risk-stratifying patients with AHF in the ED have limited applicability.
Setting: The registry included patients from 34 different hospitals in Spain.
Synopsis: This study analyzed clinical variables from a cohort of 4,897 AHF patients to determine predictors of patient outcomes. Thirteen clinical variables were identified as independent predictors of 30-day mortality and were incorporated into a risk score calculator (MEESSI-AHF). The risk score includes variables such as vital signs, age, labs values, and performance status. A second cohort of 3,229 patients were used to validate the risk score. The risk score effectively discriminates patients into low-, intermediate-, and high-risk patients. One important limitation is a high number of missing values in derivation cohort that required advanced statistics to overcome. The generalizability of the population studies (Spanish population) to other countries is still unclear. A risk score that can reasonably identify low-risk patients may be the most clinically useful in order to identify patients that either can be treated effectively in the emergency department and may not warrant inpatient admission.
Bottom line: The MEESSI-AHF risk score may be a helpful tool in identifying the risk of 30-day mortality in patients who present to the ED with AHF, but it is currently unclear if the score can be generalized to other populations.

Two scoring systems helpful in diagnosing heparin-induced thrombocytopenia
SAN DIEGO – Both the 4Ts Score and the HIT Expert Probability (HEP) Score are useful in clinical practice for the diagnosis of heparin-induced thrombocytopenia, but the HEP score may have better operative characteristics in ICU patients, results from a “real world” analysis showed.
“The diagnosis of heparin-induced thrombocytopenia (HIT) is challenging,” Allyson M. Pishko, MD, one of the study authors, said at the biennial summit of the Thrombosis & Hemostasis Societies of North America. “The 4Ts Score is commonly used, but limitations include its low positive predictive value and significant interobserver variability.”
One external prospective study showed operating characteristics similar to those of 4Ts scores (Thromb Haemost 2015;113[3]:633-40).
The aim of the current study was to validate the HEP Score in a “real world” setting and to compare the performance of the HEP Score versus the 4Ts Score. The researchers enrolled 292 adults with suspected acute HIT who were hospitalized at the University of Pennsylvania or affiliated community hospitals, and who had HIT laboratory testing ordered.
The HEP Score and the 4Ts Score were calculated by a member of the clinical team and were completed prior to return of the HIT lab test result. The majority of scorers (62%) were hematology fellows, followed by attendings (35%), and residents/students (3%). All patients underwent testing with an HIT ELISA and serotonin-release assay (SRA). Patients in whom the optical density of the ELISA was less than 0.4 units were classified as not having HIT. The researchers used the Wilcoxon rank-sum test to compare HEP and 4Ts Scores in patients with and without HIT.
Of the 292 patients, 209 were HIT negative and 83 had their data reviewed by an expert panel. Of these 83 patients, 40 were found to be HIT negative and 43 were HIT positive, and their mean ages were 65 years and 63 years, respectively. Among the cases found to be positive for HIT, 93% had HIT ELISA optical density of 1 or greater and 69.7% were SRA positive. The median HEP Score in patients with and without HIT was 8 versus 5 (P less than .0001).
At the prespecified screening cut-off of 2 or more points, the HEP Score was 97.7% sensitive and 21.9% specific, with a positive predictive value of 17.7% and a negative predictive value of 98.2%. A cut-off of 5 or greater provided 90.7% sensitivity and 47.8% specificity with a positive predictive value of 23.1% and a negative predictive value of 96.8%. The mean time to calculate the HEP Score was 4.1 minutes.
The median 4Ts Score in patients with and without HIT was 5 versus 4 (P less than .0001), Dr. Pishko reported. A 4Ts Score of 4 or greater had a sensitivity of 97.7% and specificity of 32.9%, with a positive predictive value of 20.1% and a negative predictive value of 98.8%.
The area under the ROC curves for the HEP Score and 4Ts Score were similar (0.81 vs. 0.76; P = .121). Subset analysis revealed that compared with the 4Ts Score, the HEP Score had better operating characteristics in ICU patients (AUC 0.87 vs. 0.79; P= .029) and with trainee scorers (AUC 0.79 vs. 0.73; P = .032).
“Our data suggest that either the HEP Score or the 4Ts Score could be used in clinical practice,” Dr. Pishko said.
The National Institutes of Health funded the study. Dr. Pishko reported having no financial disclosures.

The researchers enrolled 292 adults with suspected acute HIT who were hospitalized at the University of Pennsylvania or affiliated community hospitals, and who had HIT laboratory testing ordered.
The HEP Score and the 4Ts Score were calculated by a member of the clinical team and were completed prior to return of the HIT lab test result. The majority of scorers (62%) were hematology fellows, followed by attendings (35%), and residents/students (3%). All patients underwent testing with an HIT ELISA and serotonin-release assay (SRA). Patients in whom the optical density of the ELISA was less than 0.4 units were classified as not having HIT. The researchers used the Wilcoxon rank-sum test to compare HEP and 4Ts Scores in patients with and without HIT.
Of the 292 patients, 209 were HIT negative and 83 had their data reviewed by an expert panel. Of these 83 patients, 40 were found to be HIT negative and 43 were HIT positive, and their mean ages were 65 years and 63 years, respectively. Among the cases found to be positive for HIT, 93% had HIT ELISA optical density of 1 or greater and 69.7% were SRA positive. The median HEP Score in patients with and without HIT was 8 versus 5 (P less than .0001).
At the prespecified screening cut-off of 2 or more points, the HEP Score was 97.7% sensitive and 21.9% specific, with a positive predictive value of 17.7% and a negative predictive value of 98.2%. A cut-off of 5 or greater provided 90.7% sensitivity and 47.8% specificity with a positive predictive value of 23.1% and a negative predictive value of 96.8%. The mean time to calculate the HEP Score was 4.1 minutes.
The median 4Ts Score in patients with and without HIT was 5 versus 4 (P less than .0001), Dr. Pishko reported. A 4Ts Score of 4 or greater had a sensitivity of 97.7% and specificity of 32.9%, with a positive predictive value of 20.1% and a negative predictive value of 98.8%.
The area under the ROC curves for the HEP Score and 4Ts Score were similar (0.81 vs. 0.76; P = .121). Subset analysis revealed that compared with the 4Ts Score, the HEP Score had better operating characteristics in ICU patients (AUC 0.87 vs. 0.79; P= .029) and with trainee scorers (AUC 0.79 vs. 0.73; P = .032).
“Our data suggest that either the HEP Score or the 4Ts Score could be used in clinical practice,” Dr. Pishko said.

Boosting bedside skills in hands-on session
A low faculty-to-learner ratio helped HM18 attendees get the most from their learning experience in the Sunday pre-conference course “Bedside Procedures for the Hospitalist.”
The pre-course blended live didactic teaching and hands-on training with simulators so participants could not only learn but also review and demonstrate techniques for many common invasive procedures hospitalists encounter in practice.
“Our goal is to make the entire bedside procedures pre-course a unique experience,” course codirector Alyssa Burkhart, MD, of the Billings (Mont.) Clinic, said in an interview before the session.
“We carefully select the curriculum to create a program most relevant to the participants and their day-to-day work in patient care,” said Dr. Burkhart.
“The low faculty-to-learner ratio coupled with ample time to practice under expert guidance separates us from others. ... It’s a privilege to share our love of procedures with this year’s SHM participants,” said Dr. Burkhart, who comoderated the session with Joshua Lenchus, DO, SFHM, of the University of Miami.
An interactive focus on bedside procedures benefits novices and experienced clinicians, said Dr. Lenchus.
The simulation experience involved practice with ultrasound as well as anatomically representative training equipment.
“Our hope is that many hospitalists may once again find that spark of interest in performing more of their own procedures. The interactive sessions embedded within the pre-course are vital to the success of our program. Many other training sessions are didactics based. We strive to keep lecture time to a minimum so that small groups can learn from the expert facilitators,” Dr. Burkhart added.
“Ample hands-on practice time, interactive experience, and direct supervision separate our pre-course from other commercially available offerings,” Dr. Lenchus said.
The agenda kicked off with vascular and intraosseous access in the morning, followed by paracentesis, thoracentesis, lumbar puncture, and basic airway management, including the use of supraglottic devices.
Dr. Burkhart noted that the course included two separate practice sessions for vascular access because of the number of technical steps and potential complications. “Attendees typically wish to spend a considerable amount of time on vascular access,” she said. “The intraosseous access station and its exceptional trainers always receive very positive feedback.”
Dr. Burkhart and Dr. Lenchus had no financial conflicts to disclose.

Practical changes for improving practice management
An all-day HM18 pre-course – “Hospitalist Practice Management: How to Thrive in a Time of Intense Change” – for hospitalist leaders and practice administrators was all about practicality.
One of the goals of the session was to provide “quick, actionable interventions that attendees can implement right away, as well as alternatives for attendees to consider, which will require some work to employ,” said John Nelson, MD, MHM, a partner at Nelson Flores Hospital Medicine Consultants, La Quinta, Calif., the medical director of the Overlake Medical Center, Bellevue, Wash., and a course codirector and a faculty presenter.
Dr. Nelson pointed out that the hospitalist practice is a unique practice model. “We can’t effectively use the same approaches that other medical specialties use to ensure we have successful practices,” he said.
The pre-course, held Sunday before the official start of HM18, included more commentary and specifics than in past years about how to prosper in the rapidly changing health care landscape and how to reduce the chance of burnout.
Topics addressed included how to find, measure, and demonstrate value; how to incorporate different types of providers and clinical support staffing into a practice to support hospitalists; and how to recruit the right people and build a desirable culture.
The pre-course also covered effective roles for a variety of providers in a hospitalist group, including nurses, scribes, and coordinators, and delineated the benefits of providing telemedicine.
For group leaders and administrators in attendance, the session also shed light on how to interact with individual providers in their group and how to collaborate to build a healthy culture and practice, Ms. Flores said.
The day began with presentations that laid out valuable information and frameworks, including “A Tour of Survey Data: What It Does and Doesn’t Tell You” and “Defining and Measuring Value.” Sessions included six didactic lectures with a question-and-answer period, as well as what Dr. Nelson has dubbed “point/counterpoint” sessions in which faculty members debated particular issues, such as work scheduling models. During the last session, “Learning From Each Other,” participants shared with other attendees their own best practices in the areas covered.
Although there is no single best way to organize a hospitalist’s practice, the course provided lots of information and perspective to help listeners decide what is best for their practice.
“Even though we work in a stressful environment of constant change, hospitalists do have some control over their destiny, and there are things they can do to make hospitalist groups thrive in this challenging environment,” Ms. Flores concluded.
