Benthic diatoms constitute keystone assemblages in riverine ecosystems, and their structure is used to support regulatory water quality assessment. However, no standard ecotoxicological tests exist using integrated responses of the benthic diatom assemblages. This work aimed to assess whether benthic diatom assemblages are responsive to different riverine contaminants through a previously developed rapid toxicity test, supporting future attempts towards its standardization and integration in both prospective and retrospective Environmental Risk Assessment (ERA) schemes. We selected two benthic diatoms assemblages likely responding similarly to pollution (similar IPS diatom index score), collected from two rivers in Northern-Central Portugal (sites: Palhal and Cabreia). Fresh whole diatom assemblages were exposed for 48 h to five model contaminants (glyphosate, imidacloprid, SDS, CuSO 4 , and Pb). At the end of the test, changes induced by the exposures in overall yield and in the yield of each diatom genus were assessed. The assemblage collected at Palhal was invariably more responsive and sensitive than that collected at Cabreia, both considering overall and genus-specific yields, regardless of the tested contaminant. Achnanthes, Fragilaria and Navicula were the most responsive genus, regardless of the tested contaminant or assemblage. The distinct response profiles observed for the two assemblages to the same contaminants at the same concentration ranges suggest that using this test method to support prospective ERA is inadequate. However, the method can be an asset supporting retrospective ERA, as the responses seem to be shaped by the interplay of resilience drivers promoted by the local conditions, e.g. adaptive changes in assemblage structure., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2020 Elsevier B.V.

Background: In Portugal's capital, Lisbon, there are 19 public showers (PS) attended by a vulnerable population., Aim: To describe the assessment and interventions performed during nursing consultations., Method: This is a quantitative, observational, and cross-sectional study., Findings: In a convenience sample of 77 users, 52% are females, 43% are single, 52% do not possess any economic resources, 87% have mental health issues, and 32% are homeless. The main nursing focuses found were: arterial hypertension, disease management skills, and emotional suffering. The most used nursing intervention is listening, followed by the expression of feelings, valuing the individual and his/her story, analyzing causes, providing support, and comforting., Conclusions: This study shows that the main focus of the nursing care in these facilities is the human being. The respect for individuality and dignity was the primary concern, in an attempt to empower the individual to better manage his/her health and illness processes.
