Drought-compounded stress and immune function in Kenyan pastoralist boys and girls occupying contrasting climate zones.

Background And Aim: We provide ethnographic, photovoice, and psychosocial stress data (food and water insecurity, potentially traumatic events, stress biomarkers) documenting the joys, hazards, and stressors of adolescents engaging in climate-sensitive pastoralist livelihoods in a global climate change hot spot. We aim to holistically capture socio-environmental relationships characterised by climate sensitive livelihoods and forms of precarity exacerbated by climate change.

Subjects And Methods: Qualitative and quantitative methods were integrated to understand the embodied toll of hazards that Samburu pastoralists faced based on a sample of 161 young people.

Clippers are superior to scissors in the collection of hair for chemical analysis in companion dogs: a Dog Aging Project preliminary study.

Objective: To identify the safest, most efficient method for hair sample collection from companion dogs among clippers, scissors, and razors and to validate obtained samples with cortisol concentration analysis.

Animals: 25 healthy, privately owned dogs.

Methods: 2 hair samples were collected from each dog's ischiatic region with different implements (scissors, razors, or clippers).

Hemoglobin measurement in venous blood compared with pooled and single-drop capillary blood: a method-comparison study in a controlled and survey setting in Uganda among children and women.

Background: Standard practice for estimating anemia in population-based surveys is to use a point-of-care device to measure hemoglobin (Hb) in a single drop of capillary blood. Emerging evidence points to larger than expected differences in Hb concentration depending on the blood source.

Objective: We evaluated use of different blood sources to measure Hb with a HemoCue 201+ analyzer compared with the reference method of venous blood tested with a Sysmex XN-450 hematology analyzer.

Associations between childhood maltreatment and physiological dysregulation in adulthood: Methodological decisions and implications.

Background: Childhood maltreatment is linked with health problems in adulthood. Theoretical models suggest that maltreatment leads to dysregulation in several bodily systems, and this has been corroborated using measures of physiological function (i.e.

Mineral Nutrition of Samburu Adolescents: A Comparative Study of Pastoralist Communities in Kenya.

Objectives: This study aimed to characterize mineral nutrition (copper, magnesium, selenium, and zinc) in Samburu pastoralist youth, in the context of differential cultural transitions due to uneven changes in educational access, herding intensity, polygyny, and access to wild, domesticated, and market-sourced foods.

Materials And Methods: Whole dried blood spots were collected in a total of 161 youth (highlands, = 97; lowlands, = 64) to assess concentrations of: cadmium, copper, lead, magnesium, mercury, selenium, and zinc. Concentrations were determined through Inductively Coupled Mass Spectrometry.
