Estuarine Sediment Microbiomes from a Chronosequence of Restored Urban Salt Marshes.

Salt marshes play an important role in the global nutrient cycle. The sediments in these systems harbor diverse and complex bacterial communities possessing metabolic capacities that provide ecosystem services such as nutrient cycling and removal. On the East Coast of the USA, salt marshes have been experiencing degradation due to anthropogenic stressors.

Evolutionary responses of marine organisms to urbanized seascapes.

Many of the world's major cities are located in coastal zones, resulting in urban and industrial impacts on adjacent marine ecosystems. These pressures, which include pollutants, sewage, runoff and debris, temperature increases, hardened shorelines/structures, and light and acoustic pollution, have resulted in new evolutionary landscapes for coastal marine organisms. Marine environmental changes influenced by urbanization may create new selective regimes or may influence neutral evolution via impacts on gene flow or partitioning of genetic diversity across seascapes.

Prolonged Grief Disorder in a Diverse College Student Sample.

: The purpose of this study was to explore the rate of prolonged grief disorder (PGD) and associated factors in a large sample of diverse college students. Sources of grief support and perceived helpfulness of support were also examined. An online survey was administered to bereaved students at three colleges at the City University of New York.

Mental Health Among Children Older than 10 Years Exposed to the Haiti 2010 Earthquake: a Critical Review.

Purpose Of Review: There is evidence that the exposure to a major natural disaster such as the 2010 earthquake in Haiti may have devastating short- and long-term effects on children's mental health and overall development. This review summarizes what has been reported in the past 3 years (2017-2020) regarding emotional, psychological, and behavioral effects of exposure to this particular earthquake on children 10 years and older.

Recent Findings: Twenty-six articles were screened, of which twenty-one were selected for final analysis.

Reliability of labeling red cell units with minor antigen historical results and process considerations.

Background: Several approaches are used by blood centers when providing minor (non-ABO/D) antigen-negative RBCs to hospitals. Details vary but include providing results on the unit labeling intended for clinical use without retyping or providing results on packing documents or via computer query requiring confirmation. Recent regulatory changes allow labeling with historical minor antigen results, defined as previously performed by the donor center on two different donations with results linked to the donor and confirmed concordant.

Cost Effectiveness of Environmental Lead Risk Mitigation in Low- and Middle-Income Countries.

Environmental remediation efforts in low- and middle-income countries have yet to be evaluated for their cost effectiveness. To address this gap we calculate a cost per Disability Adjusted Life Year (DALY) averted following the environmental remediation of the former lead smelter and adjoining residential areas in Paraiso de Dios, Haina, the Dominican Republic, executed from 2009 to 2010. The remediation had the effect of lowering surface soil lead concentrations to below 100 mg/kg and measured geometric mean blood lead levels (BLLs) from 20.

Exploring Skills-Based Competencies Through Geriatric Care Management Modules.

As educational competencies in gerontology continue to evolve, skills-based competencies (from beginner to expert level) endure as the hallmarks of the field. This study explored the impact of exposure to "active learning" modules for the practice of professional geriatric care management (GCM) on beginning gerontology students and their ability to acquire core knowledge and more advanced skills related to assessment and counseling community-based older adults. Working with a group of "nontraditional" students, many having previous caregiving experience and working with older adults in direct care and allied health care roles, evaluation of these modules show that early exposure to "advanced" professional practice can be an effective approach for introducing higher-level competencies to beginning gerontology students.

Tuberculosis prevention project.

This article reports the findings from a clinical study that examined the impact of health education and counseling on the decision of a patient infected with tuberculosis (TB) to complete a regimen of isoniazid (INH) chemoprophylaxis for 6 months to prevent TB. Forty patients were divided into two groups; both groups were administered a questionnaire to collect demographic data and medical history. One group received additional health education and counseling independent of clinic staff, and the other group only received health education and counseling from clinic staff.

Ammonium chloride inhibits basal degradation of newly synthesized collagen in human fetal lung fibroblasts.

The objective of this work was to characterize basal degradation of newly synthesized collagen in human fetal lung fibroblasts. Analysis of 22 separate determinations showed that in cells incubated under normal conditions, the level of intracellular degradation was normally distributed with a mean of 15.2% and a standard deviation of 2.
