Title Effects of adjustable dynamic bedroom lighting in a maternity ward Type Journal Article
Year (down) 2019 Publication Journal of Environmental Psychology Abbreviated Journal Journal of Environmental Psychology
Volume 62 Issue Pages 59-66
Keywords Human Health
Abstract There exists initial evidence for beneficial daylight effects in hospital bedrooms. However, study results with automatically controlled dynamic bedroom lights were so far inconclusive. It can be hypothesized that inclusion of critically ill patients and unpleasant fixed bright light stimuli so far could have masked non-visual light effects on patient's sleep, mood and circadian physiology.

Therefore, a temporarily adjustable dynamic light was installed in double bedrooms in a maternity clinic. Although mothers were exposed to fixed morning bright light under dynamic light they were allowed to adjust light intensities the rest of the day. In contrast, light colours were automatically changed over 24 h and could not be altered. Double bedrooms with standard switchable light were utilized as active control condition.

A sample of 72 women, giving birth to healthy term babies, were randomly assigned to bedrooms with dynamic or standard light. Light conditions adjusted by mothers, sleep quality, mood and diurnal melatonin level, as well as physical activity levels of mothers and neonates, were recorded.

Mothers exposed themselves and their babies to higher daytime and lower evening light levels under dynamic light compared to standard light after the period of fixed morning bright light exposure had ended. Although no overall effects on maternal parameters could be observed under dynamic light, we could reveal an earlier daily onset of neonatal physical activity levels in these bedrooms.

To conclude, this study indicates that an adjustable dynamic light may substantially affect indoor light exposure in a maternity ward. Further studies are necessary to explore light effects on mothers and substantiate study results on neonates.

Title Changing the colour of night on urban streets – LED vs. part-night lighting system Type Journal Article
Year (down) 2019 Publication Socio-Economic Planning Sciences Abbreviated Journal Socio-Economic Planning Sciences

Abstract Many cities in the United Kingdom are upgrading the streetlights to white light-emitting diode (LED) lamps for reducing the electricity costs and attaining the sustainable energy solutions. Installation of LED lamps on urban street requires higher installation costs and a long-term period to payback benefits of replacing outdated streetlights in terms of energy savings and costs. To achieve the short-term energy efficiency of urban street lighting, city councils sometimes adopt the part-night lighting system particularly in the residential areas. The Coventry City Council recently replaced 29,701 existing sodium lights with LED lamps. This paper performs the economic analyses to understand the feasibility of two street lighting systems: LED lamps and ‘part-night’ lightings on the Coventry streets during the twenty-year period assuming the return period of investment is twenty years. The projection of energy consumption and costs for LED lamps and part-night lighting systems shows that electricity can be saved by 44% and 21% comparing to current electricity usages, respectively. Considering the budgetary constraints of Coventry City Council, this paper concludes that the part-night lighting system may be beneficial in short-term period, but it is economically feasible to replace the existing lower efficiency lights with LED lamps.

Title Dim light at night impairs recovery from global cerebral ischemia Type Journal Article
Year (down) 2019 Publication Experimental Neurology Abbreviated Journal Exp Neurol
Volume in press Issue Pages

Abstract Nighttime lighting is one of the great conveniences of modernization; however, there is mounting evidence that inopportune light exposure can disrupt physiological and behavioral functions. Hospital patients may be particularly vulnerable to the consequences of light at night due to their compromised physiological state. Cardiac arrest/cardiopulmonary resuscitation (CA) was used to test the hypothesis in mice that exposure to dim light at night impairs central nervous system (CNS) recovery from a major pathological insult. Mice exposed to dim light at night (5lx) had higher mortality in the week following cardiac arrest compared to mice housed in dark nights (0lx). Neuronal damage was significantly greater in surviving mice exposed to dim light at night after CA versus those housed in dark nights. Dim light at night may have elevated neuronal damage by amplifying pro-inflammatory pathways in the CNS; Iba1 immunoreactivity (an indication of microglia activation) and pro-inflammatory cytokine expression were elevated in mice exposed to dim light at night post-CA. Furthermore, selective inhibition of IL-1beta or TNFalpha ameliorated damage in mice exposed to dim light at night. The effects of light at night on CA outcomes were also prevented by using a wavelength of nighttime light that has minimal impact on the endogenous circadian clock, suggesting that replacing broad-spectrum nighttime light with specific circadian-inert wavelengths could be protective. Together, these data indicate that exposure to dim light at night after global cerebral ischemia increases neuroinflammation, in turn exacerbating neurological damage and potential for mortality.

Title Factors related to the risk of pedestrian fatality after a crash in Spain, 1993–2013 Type Journal Article
Year (down) 2019 Publication Journal of Transport & Health Abbreviated Journal Journal of Transport & Health
Volume 12 Issue Pages 279-289
Keywords Public Safety
Abstract Introduction

The aim of this study was to quantify the magnitude of association between pedestrian fatalities during the first 24 h after a crash and pedestrian-, driver-, vehicle- and environment-related characteristics in Spain from 1993 to 2013.

Methods

Data were analyzed for all 203,622 traffic crashes involving a pedestrian and a motor vehicle recorded in the Spanish Registry of Road Crashes with Victims. After multiple imputation for missing values, crude (CMRR) and adjusted mortality rate ratios (AMRR) were obtained for each variable with Poisson regression models.

Results

Pedestrian risk of death after a crash increased nearly exponentially with pedestrian age. Male sex, committing an infraction and having a physical defect were also associated with a higher risk of death (AMRR 1.27, 95%CI 1.17–1.37 for physical defect). Regarding driver-related factors associated with pedestrian fatalities, visual defects (AMRR 1.21, 95%CI 1.08–1.37) and the commission of a speed infraction (AMRR 2.59, 95%CI 2.43–2.76) increased the risk. Heavy vehicles (trucks, vans, buses) and the presence of passengers were also associated with a higher risk of pedestrian death. The risk of pedestrian death was lower for crashes that occurred between 12:00 and 14:00, in good light conditions, at intersections, and when the pedestrian was on a sidewalk. Risk was higher in crashes in rural areas with fewer than 5000 inhabitants.

Conclusions

We identified several factors strongly associated with the risk of pedestrian fatality; some of these factors are analyzed here for the first time. This knowledge is potentially useful in the design and prioritization of measures intended to increase pedestrian safety.
