Erythrocyte sedimentation rate in the evolution of covid -19 patients attended at the CLAS health center, Nuevo Lurin-2021
<p>Abstract</p> <p><strong>Background:</strong> To determine the values of the erythrocyte sedimentation rate in the evolution of patients with COVID -19 with treatment attended at the CLAS Health Center, Nuevo Lurín.</p> <p><strong>Methods:</strong> The research was applied with an observational and descriptive method. The approach was quantitative, applied and cross-sectional. The study population was 13,000 patients in the CLAS center in Nuevo Lurin. After applying the inclusion and exclusion criteria, there were only 45 male and female patients attended at the CLAS Health Center in Nuevo Lurin between February and June 2021, to whom the capillary method was applied in order to determine the values of the erythrocyte sedimentation rate in the evolution of COVID-19 patients. The data collection instrument was a record card.</p> <p><strong>Results:</strong> It was compared that between male and female sex, there are statistically significant differences between the 45 COVID-19 patients evaluated. Higher values were identified in 7 male patients, while in women there was 1 patient with elevated values of erythrocyte sedimentation rate. This shows that there is a higher incidence of erythrocyte sedimentation rate in males.</p> <p><strong>Conclusion: </strong>Values of erythrocyte sedimentation rate were determined in 45 patients with COVID-19 evolution with treatment attended at the CLAS Health Center in Nuevo Lurin and confirming that erythrocyte sedimentation rate evolves significantly in COVID-19 patients.</p>

Data from: Fishes alleviate the impacts of sediments on host corals
<p>Mutualisms play a critical role in ecological communities, however the importance and prevalence of mutualistic associations can be modified by external stressors. On coral reefs, elevated sediments are a major stressor, reducing the health of corals and damaging reef resilience. Here, we investigated the influence of sediment stress on the mutualistic relationship between small damselfishes (Dascyllus aruanus and Pomacentrus moluccensis) and their coral host (Pocillopora damicornis). In an aquaria experiment, corals were exposed to sedimentation rates of ~100 mg cm-2 day-1, with and without symbiont fish to test whether: (1) fishes influence the accumulation of sediments on coral hosts, and (2) fishes moderate partial colony mortality and/or condition. Colonies with fishes accumulated much less sediment compared to colonies without fishes, and this effect was strongest for colonies with D. aruanus (five-fold less sediment than controls) as opposed to P. moluccensis (two-fold less sediment than controls). Colonies with symbiont fishes also had up to 10-fold less sediment-induced partial mortality, as well as higher chlorophyll and protein concentrations. These results demonstrate that fish mutualisms vary in the strength of their benefits and indicates that some mutualistic or facilitative interactions might become more important for species health and resilience as stress levels increase.</p>
