AI Article Synopsis

  • * HCV incidence declined by 36.4%, dropping from 3.3 to 2.1 cases per 100,000 population, with the highest rates seen among individuals aged 15 to 39, primarily due to injecting drug use.
  • * Despite the decline, hepatitis C continues to pose a significant public health risk, highlighting the need for targeted prevention strategies aimed at injection drug use in the 15 to 39 age group.

Article Abstract

The purpose of this study was to determine trends in disease incidence and recent patterns of hepatitis C virus (HCV) transmission in Canada, using the Enhanced Hepatitis Strain Surveillance System (EHSSS). Demographic, clinical, and potential risk factor information on newly acquired HCV infection, from 1998 to 2004, was collected using standardized questionnaires. During this time period, the reported incidence of newly acquired HCV infection declined by 36.4% from 3.3 cases per 100,000 in 1998, to 2.1 cases per 100,000 in 2004. The disease incidence peaked at 15 to 39 y of age, confirming injecting drug use as the most frequently reported route of transmission. The proportion of cases attributed to health care-acquired HCV infection decreased over this time period. Although the incidence of newly acquired HCV infection in the EHSSS was found to be declining, hepatitis C remains an important public health threat to Canadians. Prevention efforts for HCV should focus on injection drug use, especially for people aged 15 to 39 y.

Interchangeability of Contemporary Semi-adjustable Articulators Used Over Time: An Study.

J Contemp Dent Pract

September 2024

Department of Preventive and Restorative Dentistry, School of Dental Medicine, University of Pennsylvania, Philadelphia, Pennsylvania, United States.

Aim: The purpose of this study is to investigate the interchangeability of newly acquired, short-term used, and long-term used semi-adjustable articulators.

Materials And Methods: Metal analogs of partially dentate maxillary and mandibular arches were mounted on twelve semi-adjustable Stratos 300 articulators, divided into three groups based on usage over time: New, short-term used (<2 years), long-term used (>2 years) articulators. Each articulator was calibrated according to manufacturer guidelines, ensuring consistency.

Cold agglutinin syndrome is a form of acquired hemolytic anemia that typically arises from underlying conditions, such as infections, autoimmune disorders or lymphoid malignancies. The majority of patients remain asymptomatic and are diagnosed with anemia through routine complete blood count (CBC) testing. The present study describes the case of a male patient in his 50s who sought a second opinion at the authors' clinic due to newly detected anemia.

Chronic myeloid leukemia and Philadelphia chromosome-positive acute lymphoblastic leukemia patients largely benefit from an expanding tyrosine kinase inhibitors (TKIs) toolbox that has improved the outcome of both diseases. However, TKI success is continuously challenged by mutation-driven acquired resistance and therefore, close monitoring of clonal genetic diversity is necessary to ensure proper clinical management and adequate response to treatment. Here, we report the case of a ponatinib-resistant Philadelphia chromosome-positive acute lymphoblastic leukemia (Ph + ALL) patient harboring a BCR::ABL1 p.
