Comparative Study of Physical Activity, Leisure Preferences, and Sedentary Behavior among Portuguese, Italian, and Spanish University Students.

Objective: The objective of this study is to describe and compare the levels of physical activity, preferences for leisure-time physical activity, and the frequency of non-sedentary behaviors of Portuguese, Italian, and Spanish students attending higher education.

Methods: A total of 1354 students (21.2 ± 2.

Knowledge, attitudes and practices about air pollution and its health effects in 6th to 11th-grade students in Colombia: a cross-sectional study.

Introduction: Globally, air pollution is the leading environmental cause of disease and premature death. Raising awareness through environmental education and adequate communication on air quality could reduce the adverse effects. We aimed to assess the knowledge, attitudes, and practices (KAP) regarding air pollution and health and determine the factors associated with these KAP in children and adolescents.

Impacts of soil erosion and climate change on the built heritage of the Pambamarca Fortress Complex in northern Ecuador.

The Pambamarca fortress complex in northern Ecuador is a cultural and built heritage with 18 prehispanic fortresses known as Pucaras. They are mostly located on the ridge of the Pambamarca volcano, which is severely affected by erosion. In this research, we implemented a multiscale methodology to identify sheet, rill and gully erosion in the context of climate change for the prehistoric sites.

Methane and carbon dioxide cycles in lakes of the King George Island, maritime Antarctica.

Freshwater ecosystems are important contributors to the global greenhouse gas budget and a comprehensive assessment of their role in the context of global warming is essential. Despite many reports on freshwater ecosystems, relatively little attention has been given so far to those located in the southern hemisphere and our current knowledge is particularly poor regarding the methane cycle in non-perennially glaciated lakes of the maritime Antarctica. We conducted a high-resolution study of the methane and carbon dioxide cycle in a lake of the Fildes Peninsula, King George Island (Lat.

Operation of a triage committee for advanced life support during the COVID-19 pandemic.

Background: During the first weeks of March 2020 in Spain, the cases of severe respiratory failure progressively increased, generating an imbalance between the clinical needs for advanced life support (ALS) measures and the effective availability of ALS resources. To address this problem, the creation of triage committees (TC) was proposed, whose main function is to select the best candidates to receive ALS. The main objective of our study is to describe the clinical characteristics of the patients evaluated by the TC of the Alcorcón Foundation University Hospital (AFUH) during the first wave of SARS CoV-2.

Leaf Supplementation as a Glycemic Control Strategy in Subjects with Prediabetes.

(MO) is a multipurpose plant with a high polyphenol content, which is being increasingly consumed to lessen the risk of chronic metabolic diseases such as Type 2 diabetes; however, scientific evidence from clinical trials is scarce. A double-blind, randomized, placebo-controlled, parallel group intervention study with MO leaves as a food supplement was conducted in subjects with prediabetes. They consumed six daily capsules of MO dry leaf powder (2400 mg/day) (MO, = 31) or placebo (PLC, = 34) over 12 weeks.

Temperature differently affected methanogenic pathways and microbial communities in sub-Antarctic freshwater ecosystems.

Freshwater ecosystems are responsible for an important part of the methane (CH) emissions which are likely to change with global warming. This study aims to evaluate temperature-induced (from 5 to 20 °C) changes on microbial community structure and methanogenic pathways in five sub-Antarctic lake sediments from Magallanes strait to Cape Horn, Chile. We combined in situ CH flux measurements, CH production rates (MPRs), gene abundance quantification and microbial community structure analysis (metabarcoding of the 16S rRNA gene).

The watching-eyes phenomenon and blood donation: Does exposure to pictures of eyes increase blood donation by young adults?

This study examined the effectiveness of exposure to a "watching-eyes image" in increasing blood donation rates among young people, a segment of the population that is particularly underrepresented among blood donors. Participants were 454 first-year university students, each of who was given a blood-donation flyer at the beginning of a lecture. Participants were randomly assigned to one of two conditions depending on whether the flyer they received bore a picture of eyes (experimental condition) or a neutral picture (control condition).

Mercury accumulation in sediments and seabird feathers from the Antarctic Peninsula.

In an effort to assess the impact of mercury in the Antarctic Peninsula, we conducted ecotoxicological research in this region during the summer of 2012 and 2013. The objectives were to assess: (a) mercury levels in sediment samples; (b) mercury accumulation in Antarctic seabird feathers: Catharacta lonnbergi (brown skua), Pygoscelis papua (gentoo penguin) and Pygoscelis antarctica (chinstrap penguin); and (c) biomagnification (BMF predator/prey) and biota sediment accumulation (BSAF skuas/sediment) factors. Mercury concentrations in sediment were relatively low.

Labeling of previous donation to encourage subsequent donation among experienced blood donors.

Objective: This study aims to examine the effects of persuasive messages focused on the labeling of previous blood donation behavior on subsequent donation among experienced blood donors.

Method: Participants (N = 410) received blood drive invitations by mail that were categorized with the labeling of the previous donation. They were randomly assigned to one of three conditions: functional labeling (which underlines the utility of their donation), social labeling (which underlines their own social value), and no label of previous donation (control condition).

[The contribution of persuasion social psychology to the retention of donors: the impact of labelling the previous donation].

The supply of blood cell products requires from the National French Blood Institute (Établissement Français du Sang - EFS) to rely upon regular blood donors. Contact with donors, tailored to individuals as much as possible, helps them to donate on a regular basis. Within the context of a research program conducted with the Psychology Department of the Université de Caen Basse-Normandie, persuasive theoretical models from social psychology have been tested.

[The contribution of persuasion social psychology to the retention of donors: models to elaborate mailing to the donors].

The supply of blood cell products required from the National French Blood Institute (Établissement français du sang [EFS]) relies upon regular blood donors. Contact with donors, tailored to individuals as much as possible, helps them to donate on a regular basis. To communicate as efficiently as possible, the content of the mailings has to be adapted to individuals, each according to his/her motivation and the way he or she perceives and processes the information.
