- Background: Worldwide, different strategies have been chosen to face the COVID-19-patient surge, often affecting access to health care for other patients. This observational study aimed to investigate whether the standard of burn care changed globally during the pan-demic, and whether country acute accent s income, geographical location, COVID-19-transmission pat-tern, and levels of specialization of the burn units affected reallocation of resources and access to burn care.Methods: The Burn Care Survey is a questionnaire developed to collect information on the capacity to provide burn care by burn units around the world, before and during the pandemic. The survey was distributed between September and October 2020. McNemar`s test analyzed differences between services provided before and during the pandemic, chi 2 or Fishers exact test differences between groups. Multivariable logistic regression analyzed the independent effect of different factors on keeping the burn units open during the pandemic.Results: The survey was completed by 234 burn units in 43 countries. During the pandemic, presence of burn surgeons did not change (p = 0.06), while that of anesthetists and dedi-cated nursing staff was reduced (< 0.01), and so did the capacity to manage patients in all age groups (p = 0.04). Use of telemedicine was implemented (p < 0.01), collaboration be-tween burn centers was not. Burn units in LMICs and LICs were more likely to be closed, after adjustment for other factors.Conclusions: During the pandemic, most burn units were open, although availability of standard resources diminished worldwide. The use of telemedicine increased, suggesting the implementation of new strategies to manage burns. Low income was independently associated with reduced access to burn care.(c) 2021 The Author(s).

- Di(2-ethylhexyl) phthalate (DEHP) is a plasticizer commonly used in PVC that may leach into the environment, and has been shown to adversely affect the health of humans and animals. We undertook a study to ascertain the neurotoxicity of DEHP in Kunming mice. This study included three rounds of testing. In the first round, Kunming mice were exposed to different concentrations of DEHP (0, 5, 50, 500 mg kg(-1) per day) after which their cognitive ability was assessed using the Morris water maze (MWM) test. The reactive oxygen species (ROS) content in tissue and the malondialdehyde (MDA) content of brains were also measured. In the second round, vitamin E (50 mg kg(-1) per day) was given daily as an anti-oxidant via the intragastric route. Cognitive deficits and locomotor activity, as well as ROS and MDA contents were tested employing the same methods. In the third round, the depressive mood of mice after DEHP exposure (500 mg kg(-1) per day) was measured using the open field test, the tail suspension test, and the forced swim test. The main findings of this study include: (1) a statistical association exists between DEHP oral exposure and spatial learning (DEHP 500 mg kg(-1) per day) and memory (DEHP 50 mg kg(-1) per day) dysfunction as ascertained by an MWM test of Kunming mice. (2) A statistical association was also found between DEHP oral exposure (50 and 500 mg kg(-1) per day) and oxidative stress (ROS and MDA) of mouse brain tissue. (3) Co-administration of vitamin E (50 mg kg(-1) per day) diminishes the elevation of ROS and MDA induced by DEHP (50 mg kg(-1) per day) from significant levels to non-significant levels. (4) Co-administration of vitamin E (50 mg kg(-1) per day) protects against mouse memory dysfunction induced by DEHP (50 mg kg(-1) per day) from being significant to being not significant. (5) In the 5 mg kg(-1) per day DEHP exposure groups, oxidative stress in brain tissue, and neurobehavioral changes were not found. (6) High dose DEHP exposure (500 mg kg(-1) per day) may induce behavioral despair in mice. Conclusions: These data suggest that DEHP is neurotoxic with regard to cognitive ability and locomotor activity.
