Article Abstract
A dipstick assay, based on Leishmania infantum antigen, for the rapid detection of Leishmania-specific antibodies in canine serum samples was developed and evaluated. After determination of optimal dipstick test conditions, test performance was compared with two existing serological tests, i.e., the direct agglutination test (DAT) and the fast agglutination screening test (FAST). In the present study the dipstick test had a sensitivity of 99.2% and a specificity of 87.9%. The DAT had a sensitivity of 97.7% and a specificity of 95.2%, whereas the FAST had also a sensitivity of 97.7% and a specificity of 93.0%. High degrees of agreement were observed between the dipstick test and DAT (93.7%; kappa value, 0.86), between the dipstick test and FAST (91.8%; kappa value, 0.82), and between the DAT and FAST (95.2%; kappa value, 0.90). The high sensitivity and ease of performance make the dipstick test very suitable for surveillance surveys.

Background: Urinary tract infections are prone to overdiagnosis, and reflex urine culture protocols offer a valuable opportunity for diagnostic stewardship in this arena. However, there is no recommended standard testing approach. Cancer patients are often excluded from reflex urine culture protocols, especially if severely immunosuppressed or neutropenic.

Objectives: To assess the incidence and clinical findings associated with the presence of ammonium urate urolithiasis in dogs with congenital portosystemic shunts.
Materials And Methods: A retrospective review of dogs diagnosed with extrahepatic portosystemic shunts or intrahepatic portosystemic shunts in 15 referral hospitals between 2010 and 2023. Data including signalment, clinical signs, physical examination findings and clinicopathologic test results at the time of the diagnosis were collected, and the presence of ammonium urate urolithiasis was recorded.

Recently, the scale and frequency of harmful algae blooms (HABs) have gradually increased, posing a serious threat to human health, marine ecosystems and economic development. For early warning, a method is required that can quickly detect and monitor microalgae. It is proposed to use aptamer targeted to Prorocentrum minimum, along with exonuclease III (Exo III), gold nanoparticles, target single-stranded DNA and hairpin structure probe to construct a new method, i.

Background: Urinalysis is a commonly performed test for the diagnosis and prognosis of kidney disease in hospitalized patients. It involves examining the chemical composition of the urine and microscopy to examine the cells and casts. In clinical settings, urinalysis is frequently delayed by several hours after sample collection and held at room temperature.

Background: Testing high-risk populations for non-visible haematuria may enable earlier detection of bladder cancer, potentially decreasing mortality. This research aimed to assess the cost-effectiveness of urine dipstick screening for bladder cancer in high-risk populations in England.
Methods: A microsimulation model developed in R software was calibrated to national incidence data by age, sex and stage, and validated against mortality data.
