Abstract
The vertebral heart scale (VHS) is widely known and used as an objective standard for the evaluation of cardiomegaly on thoracic radiographs. It, therefore, plays an important role in assessing the severity of canine heart disease. The body condition score (BCS) is a nine-scale body condition scoring system used to objectively document the body condition in dogs. Obese animals have widened precardiac and postcardiac mediastinum, fat deposits between the sternum and lungs or heart, as well as increased pericardial fat. These conditions could complicate cardiac silhouette evaluation and could, therefore, result in higher interobserver variability in the assessment of VHS. The purpose of this study was to investigate whether overweight dogs (BCS 6/9, 7/9, 8/9, and 9/9) have more variability in the interobserver VHS measurement compared with dogs with a normal BCS (BCS 4/9 and 5/9). The dogs were admitted to a private referral center for different medical reasons. The VHS was measured by three trained observers in right lateral radiographs of 18 overweight dogs and 33 dogs with a normal BCS. Bland-Altmann plots were constructed, and limits of agreement were calculated to show the variability of VHS measurements. No statistically significant differences in VHS variability were found between BCS categories, observers, sex, or age categories. In conclusion, BCS does not affect the reliability of VHS assessment among trained veterinarians.

A Higher Cardiothoracic Ratio Is Associated with 2-Year Mortality after Hemodialysis Initiation. NEPHRON EXTRA 2015; 5:100-10.

Abstract
UNLABELLED A high cardiothoracic ratio (CTR) is indicative of a cardiac disorder. However, few reports have revealed an association between the CTR and mortality in patients starting hemodialysis (HD). METHODS Patients with HD initiation (n = 387; mean age, 66.7 ± 12.7 years) were divided into the following three groups according to their CTR at HD initiation: CTR <50%, 50% ≤ CTR < 55%, and CTR ≥55%. Kaplan-Meier analysis was performed to compare 2-year all-cause mortality among these groups. Furthermore, we investigated the factors affecting their 2-year mortality using a Cox proportional hazard regression analysis. RESULTS Sixty-five patients (17%) died within 2 years after HD initiation. Kaplan-Meier analysis showed that patients with CTR ≥55% had a higher mortality rate than those in the other groups. Cox proportional hazard regression analysis was performed using parameters with p values <0.1 among these three groups [sex, age, presence or absence of ischemic heart disease, hemoglobin levels, serum albumin levels, CTR, body mass index (BMI)] and confounding factors [presence or absence of diabetes mellitus, and estimated glomerular filtration rate (eGFR)]. Age, eGFR, BMI, and CTR ≥55% at HD initiation were identified as factors influencing 2-year mortality. CONCLUSION CTR >55% is one of the most important independent factors to affect 2-year all-cause mortality. Thus, confirming the cardiac condition of patients at HD initiation with a CTR >55% may improve their survival.
