Effectiveness of taxanes following nivolumab in patients with advanced esophageal squamous cell carcinoma: a retrospective chart review of patients in ATTRACTION-3.

Background: The phase III ATTRACTION-3 study showed that second-line nivolumab monotherapy for advanced esophageal squamous cell carcinoma prolonged overall survival (OS) but did not improve progression-free survival (PFS). Subsequent systemic therapy after discontinuing nivolumab may affect these outcomes. To test this possibility, we evaluated the outcomes of treatment with taxanes after nivolumab in ATTRACTION-3.

Body-mounted robotic instrument guide for image-guided cryotherapy of renal cancer.

Purpose: Image-guided cryotherapy of renal cancer is an emerging alternative to surgical nephrectomy, particularly for those who cannot sustain the physical burden of surgery. It is well known that the outcome of this therapy depends on the accurate placement of the cryotherapy probe. Therefore, a robotic instrument guide may help physicians aim the cryotherapy probe precisely to maximize the efficacy of the treatment and avoid damage to critical surrounding structures.

Seroprevalence of leptospirosis in a rural flood prone district of Bangladesh.

Leptospirosis is a worldwide zoonotic disease. In the present investigation, a total of 89 human sera from a flood prone district of Bangladesh was screened by a one-point microscapsule agglutination test (MCAT). MCAT-positive and -doubtful sera were further tested by microscopic agglutination test (MAT) against 16 reference serovars of Leptospira interrogans, and the antibody titres determined.

Evaluation of the one-point microcapsule agglutination test for diagnosis of leptospirosis.

We have developed a one-point microcapsule agglutination test (MCAT) for the serodiagnosis of leptospirosis. The MCAT kit was evaluated for use in humans by six WHO Collaborating Centres for Reference and Research on Leptospirosis. The laboratories classified their serum samples on the basis of the microscopic agglutination test (MAT) and the following screening tests: enzyme-linked immunosorbent assay (ELISA), macroscopic (slide) agglutination test, or the complement fixation test.

Comparison of antibody titers against borrelial strains isolated in Japan by the microcapsule agglutination test for serological studies of early Lyme disease.

Results of a passive microcapsule agglutination test using 2 Japanese strains, Borrelia garinii and Borrelia afzelii, were comparable to that of the passive microcapsule agglutination test using a Swiss strain Borrelia burgdorferi IRS in detecting antibodies of an early stage of Lyme disease patients in Japan. MCAT with microcapsule sensitized strain IRS seems likely to become one of the important tools for the early diagnosis of Lyme disease in the world. The highest titer of MCAT was detected in the serum samples of patients which were taken around 2 weeks after erythema chronicum migrants.
