Rotavirus Vaccine and Intussusception
Using active surveillance, researchers enrolled 717 infants with intussusception from sub-Saharan Africa. The risk of intussusception was no higher in those who received the monovalent rotavirus vaccine than in non-immunized infants.

Antibiotic Use in Infancy Associated With Allergic Disease During Childhood
In a large population-based study, antibiotic use during the first six months of life was associated with a two-fold increase in asthma and a 1.5-fold increase in allergic disease during early childhood.

Simple Prediction Tool Facilitates Diagnosis of Heart Failure With Preserved Ejection Fraction
In patients with unexplained dyspnea, a score based on six noninvasive criteria can predict the likelihood of heart failure with preserved ejection fraction.

Mortality Risk Score for Degenerative Mitral Regurgitation
An international database of patients with significant degenerative mitral valve regurgitation was used to derive and test a score using clinical and echocardiographic data to estimate mortality with medical and surgical therapy. From seven weighted characteristics, investigators developed a 0-12 score that predicted medical and surgical long-term mortality with high discriminatory ability (C-statistic, 0.78 and 0.81, respectively). Investigators found the score added incremental information to surgical scores and believe that it will be useful for therapeutic decision-making.

Long-term Risk of Transient Atrial Fibrillation After Coronary Artery Bypass Graft Surgery
Investigators compared post-coronary artery bypass graft (CABG) atrial fibrillation (AF) to non-surgical, non-valvular AF in a large cohort derived from the Danish health system database. Despite a lower rate of oral anticoagulant use compared to non-valvular AF patients and equivalent CHA2DS2-VASc scores, post-CABG AF demonstrated a lower risk of thromboembolism, death, and recurrent AF. These data do not support the concept that post-CABG AF is the same as traditional non-valvular AF regarding thromboembolic risk.

Drug-eluting Stents Fare No Better Than Bare-metal Stents in Vein Graft Lesions
The two largest randomized trials to date have shown no advantage to drug-eluting stents compared to bare-metal stents in saphenous vein graft percutaneous interventions.

CABANA Trial Reveals New Insights About Ablation for Atrial Fibrillation
Ablation for atrial fibrillation did not reduce the composite endpoint of death, disabling stroke, serious bleeding, or cardiac arrest compared with drug therapy, although adverse events were infrequent and arrhythmia recurrence was reduced significantly.

Differences Between Type 1 and Type 2 Diabetic Neuropathy
Microstructural nerve damage in distal symmetric diabetic neuropathy differs between subjects with type 1 diabetes (T1D) and type 2 diabetes (T2D). The predominant nerve lesions in T1D correlated with hyperglycemia and nerve conduction impairment, while the predominant lesions in T2D correlated with dyslipidemia.

Planes, Pathogens, and Passengers: Infection Risk During Commercial Air Travel
Although air travel has been linked to transmission of respiratory infections, the actual risk of becoming infected during air travel is low. The risk is greatest, though, when seated within about two seats/rows of a contagious individual. Walking around the cabin increases the risk.
