Healthy hair results from a combination of good generalized health and mindful health care practices. Many nutritional deficiencies lead to poor hair health and include changes to hair structure, texture, and viability. Although the mechanisms by which individual nutrients contribute to hair growth and maintenance have yet to be fully resolved, there are a variety of risk factors that predispose an individual to a nutritional deficiency; age, malnutrition, malabsorption, and medication use are among the most common. A thorough history should be taken in a patient with a hair disturbance to identify risk factors for a nutritional deficiency, which will then guide directed laboratory testing and treatment.

January 2025
Department of Optometry and Vision Sciences, The University of Melbourne, Parkville, Australia.
Clinical Relevance: There are many recognised risk factors for retinal vein occlusions. It is plausible that musicians who play wind instruments or use their voice as their primary instrument may be at increased risk of branch retinal vein occlusions through repeated Valsalva manoeuvre.
Background: Repeated valsalva manoeuvres are commonly performed by musicians using high resistance wind instruments.
Assessing bioaccumulation with biomagnification factors from dietary bioaccumulation tests.
Integr Environ Assess Manag
January 2025
ExxonMobil Petroleum and Chemical BV, Machelen, Belgium.
Despite the fact that the UN Stockholm Convention on persistent organic pollutants specifically acknowledges that Arctic ecosystems and Indigenous communities are particularly at risk due to biomagnification of contaminants in traditional foods, the bioconcentration factor (BCF) of substances in fish remains the preferred metric for identifying the biomagnification potential of organic substances. The BCF measures uptake of substances from water in water-breathing organisms, but not biomagnification of contaminants from food sources. The purpose of this study is to investigate how the biomagnification factor (BMF) can be used in bioaccumulation assessments.
