Within the southern California Current ecosystem there are two well-documented breaks in marine community structure at Point Conception and Punta Eugenia. We explored the presence of similar breaks in a diverse zooplankton community through metabarcoding of mixed net tow tissue samples collected during an expedition from Monterey to Baja California in February of 2012. We recovered a high diversity of species as well as patterns of species presence that align with their previously documented ranges in this region. We found a clear break at Punta Eugenia in overall zooplankton community structure, while Point Conception was weakly linked to changes in community structure. We analyzed this dataset through two parallel bioinformatic pipelines to examine the robustness of these results. Our overall conclusions were consistent across both pipelines, however there were differences in species detection. This study illustrates the utility of metabarcoding analysis on mixed tissue samples for recovering known patterns of diversity, as well as allowing elucidation of broad patterns of community differentiation across many groups of organisms.

Designing and incorporating integrated oral health care pathways for pediatric and adult patients: touchpoints in a dental setting.
BMC Oral Health
January 2025
National Center for Professional Training, Ministry of Health and Medical Education, Tehran, Iran.
Background: Maintenance of oral health, prevention, and health promotion stand as primary competencies for dental graduates. Consequently, it is necessary to promote such an approach in dental schools, which are traditionally focused on treatment, to improve the attitude and practice of students in the field of prevention, the final result of which is the reduction of oral and dental diseases in patients. The study aimed to design Integrated Oral Health Care Pathways (IOHCPs) for adults and children referred to Tehran University of Medical Sciences (TUMS), School of Dentistry.

Background: Uncontrolled hypertension is the leading modifiable risk factor for cardiovascular disease mortality and remains high in low-middle income countries like Haiti. Barriers and facilitators to achieving hypertension control in urban Haiti remain poorly understood. Elucidating these factors could lead to development of successful interventions.

January 2025
Chronic Disease and Injury Prevention, Public Health Ontario, 480 University Avenue, Toronto, Ontario, M5G 1V2, Canada.
Background: Road-related injuries and deaths are among the most significant and avoidable public health problems in Canada. Modifications to the built environment (BE) can reduce injury rates for vulnerable road users (VRUs) and other priority populations who experience disproportionate risk. This paper highlights public health professionals' experiences working in injury prevention across Ontario public health units (PHUs) navigating barriers and facilitators to BE change.

Point-of-care ultrasound (POCUS) has emerged as a standard of care across a variety of healthcare settings due to its ability to provide critical clinical information and as well as procedural guidance to clinicians directly at the bedside. Implementation of enterprise imaging (EI) strategies is needed such that POCUS images can be appropriately captured, indexed, managed, stored, distributed, viewed, and analyzed. Because of its unique workflow and educational requirements, reliance on traditional order-based workflow solutions may be insufficient.

As conservation agricultural practices continue to spread, there is a need to understand how reduced tillage impacts soil microbes. Effects of no till (NT) and disk till (DT) relative to moldboard plow (MP) were investigated in a long-term experiment established on Chernozem. Results showed that conservation practices, especially NT, increased total, active and microbial biomass carbon.
