Comparative risk of cerebral venous sinus thrombosis (CVST) following COVID-19 vaccination or infection: A national cohort study using linked electronic health records.

To inform the public and policy makers, we investigated and compared the risk of cerebral venous sinus thrombosis (CVST) after SARS-Cov-2 vaccination or infection using a national cohort of 2,643,699 individuals aged 17 y and above, alive, and resident in Wales on 1 January 2020 followed up through multiple linked data sources until 28 March 2021. Exposures were first dose of Oxford-ChAdOx1 or Pfizer-BioNTech vaccine or polymerase chain reaction (PCR)-confirmed SARS-Cov-2 infection. The outcome was an incident record of CVST.

Corprological and haematological parameters of albino mice (Mus musculus) concurrently infected with Heligmosomoides bakeri and Trypanosoma brucei.

The effect of concurrent infection with Trypanosoma brucei (T. brucei) and Heligmosomoides bakeri (H. bakeri) was investigated in this study.

Abnormal biochemical and haematological indices in trypanosomiasis as a threat to herd production.

Blood samples were collected from 46 domestic ruminants comprising of 23 trypanosomiasis infected and 23 uninfected control groups to study some biochemical and haematological effects of trypanosomiasis under natural condition. The effect of trypanosome infection in ruminant animals showed that infected animals had significantly lower (P<0.05) packed cell volume, erythrocyte count and higher (P<0.

Use of a decision-analytic model to support the use of a new oral US contrast agent in patients with abdominal pain.

Rationale And Objectives: The authors performed this study to compare the cost and diagnostic abilities of ultrasound (US) performed with and without the use of an oral contrast material recently approved by the U.S. Food and Drug Administration.
