Pandemic impact on higher education faculty self‐care, burnout, and compassion satisfaction

This correlational study examined the relationship between self‐care, burnout, compassion satisfaction, and secondary traumatic stress among higher education faculty members during the COVID‐19 pandemic. The results inform higher education faculty members about the effects of self‐care and suggest strategies to reduce burnout, compassion satisfaction and secondary traumatic stress.

Effects of air pollution exposure on inflammatory and endurance performance in recreationally trained cyclists adapted to traffic-related air pollution.

The aim of the present study was to analyze the effects of traffic-related air pollution (TRAP) on markers of inflammatory, neuroplasticity, and endurance performance-related parameters in recreationally trained cyclists who were adapted to TRAP during a 50-km cycling time trial (50-km cycling TT). Ten male cyclists performed a 50-km cycling TT inside an environmental chamber located in downtown Sao Paulo (Brazil), under TRAP or filtered air conditions. Blood samples were obtained before and after the 50-km cycling TT to measure markers of inflammatory [interleukin-6 (IL-6), C-reactive protein (CRP), interleukin-10 (IL-10), intercellular adhesion molecule-1 (ICAM-1)] and neuroplasticity [brain-derived neurotrophic factor (BDNF)]. Rating of perceived exertion (RPE), heart rate (HR), and power output (PO) were measured throughout the 50-km cycling TT. There were no significant differences between experimental conditions for responses of IL-6, CRP, and IL-10 (P > 0.05). When compared with exercise-induced changes in filtered air condition, TRAP provoked greater exercise-induced increase in BDNF levels (TRAP = 3.3 ± 2.4-fold change; Filtered = 1.3 ± 0.5-fold change; P = 0.04) and lower exercise-induced increase in ICAM-1 (Filtered = 1.1 ± 0.1-fold change; TRAP = 1.0 ± 0.1-fold change; P = 0.01). The endurance performance-related parameters (RPE, HR, PO, and time to complete the 50-km cycling TT) were not different between TRAP and filtered air conditions (P > 0.05). These findings suggest that the potential negative impacts of exposure to pollution on inflammatory, neuroplasticity, and performance-related parameters do not occur in recreationally trained cyclists who are adapted to TRAP.

Impact of COVID-19 on the Internationalisation of the Spanish Agri-Food Sector

The COVID-19 pandemic has forced companies to suddenly adapt their daily operations. This has also affected the agri-food sector, which is one of the main sectors of the Spanish economy in terms of exportations. Hence, the purpose of this study is to explore how the COVID-19 pandemic has impacted the internationalisation of Spanish agri-food companies. A case study has been developed to gain understanding and insights about the COVID-19 impacts on this sector. The information has been obtained through 12 semi-structured phone interviews that have been made with international/export managers (or managers with international responsibilities) from Spanish exporting companies of the agri-food sector. This research suggests that internationalisation is a great growth opportunity for Spanish agri-food companies. However, COVID-19 has considerably impacted the sector, and they have needed to focus on identifying such impacts to manage them efficiently. In this sense, most interviewees have identified common changes and adaptations to be faced and risks generated by the pandemic that importantly influenced such companies, being the most important risks the sanitary and the payment default risk. In addition, interviewed managers have also explained main actions that were taken. By handling the COVID-19 situation in a flexible, quick and efficient way, companies will achieve international success.

Exercising under particulate matter exposure: Providing theoretical support for lung deposition and its relationship with COVID-19.

The aim of the present study was to investigate lung particulate matter (PM) deposition during endurance exercise and provide a new insight concerning how SARS-CoV-2 could be carried into the respiratory tract. The anatomical and physiological characteristics of the Human Respiratory Tract model were considered for modeling the lung PM deposition during exercise. The Monte Carlo method was performed to randomly generate different values of PM concentrations (1.0, 2.5, and 10.0 µm), minute ventilation, and duration of exercise at moderate, heavy, and severe exercise intensity domains. Compared to moderate and severe intensities, during heavy exercise (75-115 L‧min-1, duration of 10.0-60.0 min) there is greater lung deposition in the bronchiolar region (p < 0.01). In turn, there is greater deposition per minute of exercise at the severe intensity domain (115.0-145.0 L‧min-1, duration of 10.0-20.0 min, p < 0.01). Considering that SARs-CoV-2 could be adsorbed on the particles, exercising under PM exposure, mainly at the severe domain, could be harmful concerning the virus. In conclusion, beyond the traditional minute ventilation assumption, there is a time vs intensity dependence for PM deposition, whereby the severe domain presents greater deposition per minute of exercise. The results observed for PM deposition are alarming since SARs-CoV-2 could be adsorbed by particles and carried into the deeper respiratory tract.
