The Challenge Of Covid19 In The Management Of Vascular Access For Hemodialysis In An Universitary Hospital.

Introduction: Chronic kidney disease prevalence has been increasing worldwide, with an increasing need to deliver an effective treatment. During the first months of the coronavirus disease 2019 (COVID-19) pandemic healthcare systems around the world were under stress. Therefore, the aim of this study is to report a single center experience with arteriovenous fistula (AVF) creation while also evaluating the impact of COVID-19.

Dissimilar use of an external heat source for thermoregulation by shrews from different geographic regions.

Ambient temperature has a substantial influence on the thermoregulation costs of small mammals due to their high surface-to-volume ratio. Shrews are among the smallest of mammals and have adopted different behavioral and physiological strategies to deal with cold temperatures. In this study, we assessed the use of an external heat source in the thermoregulatory strategy of two Crocidurinae species, Crocidura russula and C.

Patterns and Drivers of Rodent Abundance across a South African Multi-Use Landscape.

South Africa's decentralized approach to conservation entails that wildlife outside formally protected areas inhabit complex multi-use landscapes, where private wildlife business (ecotourism and/or hunting) co-exist in a human-dominated landscape matrix. Under decentralized conservation, wildlife is perceived to benefit from increased amount of available habitat, however it is crucial to understand how distinct management priorities and associated landscape modifications impact noncharismatic taxa, such as small mammals. We conducted extensive ink-tracking-tunnel surveys to estimate heterogeneity in rodent distribution and investigate the effect of different environmental factors on abundance patterns of two size-based rodent groups (small- and medium-sized species), across three adjacent management contexts in NE KwaZulu-Natal, South Africa: a private ecotourism game reserve, mixed farms and traditional communal areas (consisting of small clusters of houses interspersed with grazing areas and seminatural vegetation).

Effectiveness of Mobile App-Based Psychological Interventions for College Students: A Systematic Review of the Literature.

Serious mental health disorders are increasing among college students and university counseling services are often overburdened. Mobile applications for mental health have been growing exponentially in the last decade and they are emerging in university settings as a promising tool to promote and intervene in college students' mental health. Additionally, considering the recent covid-19 pandemic, mHealth interventions, due to its nature and possibilities, may play an important role in these institutions.

Content validation of the symptom control outcome for heart failure patients in palliative care.

Objectives: To estimate the content validity of the Symptom Control nursing outcome for heart failure patients in palliative care and to analyze the influence of experts' experience in the judgment of the relevance of indicators.

Methods: A methodological study conducted in São Paulo in 2018, with an adaptation of Fehring's validation model. The relevance of the 11 outcome indicators was assessed by 19 experts by means of an electronically submitted survey.

Bio-Based Nanoparticles as a Carrier of β-Carotene: Production, Characterisation and In Vitro Gastrointestinal Digestion.

β-carotene loaded bio-based nanoparticles (NPs) were produced by the solvent-displacement method using two polymers: zein and ethylcellulose. The production of NPs was optimised through an experimental design and characterised in terms of average size and polydispersity index. The processing conditions that allowed to obtain NPs (<100 nm) were used for β-carotene encapsulation.

[Association of gamma glutamyltransferase, metabolic syndrome and cardiovascular risk].

Serum gamma-glutamyl transferase (GGT) has been used as a marker of alcohol induced liver disease. Recent epidemiology and pathology studies have suggested its independent role in the pathogenesis and clinical evolution of cardiovascular diseases (CVD) promoting atherosclerosis through an oxidative process leading, within the atherosclerotic plaque, to LDL oxidation, metalloproteinase activation, cell proliferation and apoptosis. Besides it is known that GGT levels rise even in the normal range, with obesity and hepatic steatosis occurs, it is thought, which originates insulin resistance (IR).
