Twenty-five years on: Widespread kelp forest decline revealed in a potential climatic refugium.

Kelp forests are key temperate ecosystems that experience the combined effects of global and local stressors throughout their distribution range. Niche modelling projections identified NW Spain, a region influenced by an intense upwelling system, as one such potential refugium. However, the recent discovery that fish overgrazing has eradicated kelp forests from certain reefs calls into question the validity of these projections.

Clinical Validation of the Nursing Diagnosis 'Inadequate Health Self-Efficacy' in People With Hypertension.

Aims: To test the clinical validity of clinical indicators and causal relationships of aetiological factors of the new nursing diagnosis of inadequate health self-efficacy in people with hypertension.

Background: The diagnosis of inadequate health self-efficacy has both theoretical and content validity. However, a clinical validation study is needed to establish an appropriate framework for distinguishing individuals who manifest this unique human response.

Investigating the Dietary Impact on Trans-Vaccenic Acid (Trans-C18:1 n-7) and Other Beneficial Fatty Acids in Breast Milk and Infant Formulas.

Maternal diet plays a significant role in the fatty acid composition of breast milk. Dietary products such as milk and meat are the primary sources of natural TFAs for humans. These peculiar fatty acids hold nutritional significance as they not only lack the detrimental effects of industrially produced fats on the endothelium characteristic, but they also exhibit anti-inflammatory properties.

Assessing the Risk Stratification of Breast Cancer Polygenic Risk Scores in a Brazilian Cohort.

Polygenic risk scores (PRSs) for breast cancer have a clear clinical utility in risk prediction. PRS transferability across populations and ancestry groups is hampered by population-specific factors, ultimately leading to differences in variant effects, such as linkage disequilibrium and differences in variant frequency (allele frequency differences). Thus, locally sourced population-based phenotypic and genomic data sets are essential to assess the validity of PRSs derived from signals detected across populations.

Kelp forests collapse reduces understorey seaweed β-diversity.

Background And Aims: Kelps are the primary foundation species in temperate subtidal rocky shores worldwide. However, global change is causing their decline with consequences for the organisms that rely on them. An accurate assessment of these consequences may depend on which attributes of the associated community are considered.
