Purpose: To compare comfort outcomes between a novel daily disposable contact lens - designed to maximize comfort - and an established control. The hypothesis was that the test lens would be superior to the control for four key comfort questionnaire items: end-of-day comfort, all-day comfort, visual comfort while driving at night, and reduction of ocular fatigue from digital device use.
Methods: This randomized, controlled, subject-masked, parallel-arm study enrolled young (18-39 years), healthy, myopic, contact lens wearers with an up-to-date prescription at 19 investigational sites in the United States.
Maximum entropy (MaxEnt) models are a class of statistical models that use the maximum entropy principle to estimate probability distributions from data. Due to the size of modern data sets, MaxEnt models need efficient optimization algorithms to scale well for big data applications. State-of-the-art algorithms for MaxEnt models, however, were not originally designed to handle big data sets; these algorithms either rely on technical devices that may yield unreliable numerical results, scale poorly, or require smoothness assumptions that many practical MaxEnt models lack.

- The tapeworm Dipylidium caninum is a common parasite in dogs, cats, and humans, with diagnosis typically relying on observing segments in feces or using microscopy, both of which may miss infections.
- A study was conducted on 100 cats in Italy and Greece, comparing various sampling methods (feces, Scotch tape test, and rectal swab) to test for D. caninum using PCR, which is a more sensitive detection method.
- Results indicated that while PCR could effectively identify D. caninum in certain samples, it also faced challenges like false negatives and variability in parasite distribution, highlighting its potential as a diagnostic tool under specific conditions.
Objective: To establish a reference interval for a feline-specific pancreatic lipase assay (Spec fPL test; Idexx Laboratories Inc) in healthy cats and determine the sensitivity and specificity of the Spec fPL test in a large group of ill cats with and without pancreatitis.
Animals: 41 healthy cats, 141 cats with clinical signs consistent with pancreatitis, and 786 stored sera with known feline pancreatic lipase immunoreactivity (fPLI) concentrations.
Methods: This was a prospective, cross-sectional, nonrandomized study.
Article Synopsis
- * Heartworm disease, caused by a nematode, can also affect cats, especially in regions where dogs are infected; although cats have some resistance, heartworm can lead to serious health issues and potentially death.
- * A study evaluated the diagnostic accuracy of a new point-of-care immunoassay for FIV, FeLV, and heartworm, showing high sensitivity and specificity compared to traditional reference methods, which can improve veterinarians' ability to diagnose
