AbstractOzone is one of the six “criteria” pollutants identified by the U.S. Clean Air Act Amendment of 1970 as particularly harmful to human health. Concentrations have decreased markedly across the United States over the past 50 years in response to regulatory efforts, but continuing research on its deleterious effects have spurred further reductions in the legal threshold. The South Coast and San Joaquin Valley Air Basins of California remain the only two “extreme” ozone nonattainment areas in the United States. Further reductions of ozone in the West are complicated by significant background concentrations whose relative importance increases as domestic anthropogenic contributions decline and the national standards continue to be lowered. These background concentrations derive largely from uncontrollable sources including stratospheric intrusions, wildfires, and intercontinental transport. Taken together the exogenous sources complicate regulatory strategies and necessitate a much more precise understanding of the timing and magnitude of their contributions to regional air pollution. The California Baseline Ozone Transport Study was a field campaign coordinated across Northern and Central California during spring and summer 2016 aimed at observing daily variations in the ozone columns crossing the North American coastline, as well as the modification of the ozone layering downwind across the mountainous topography of California to better understand the impacts of background ozone on surface air quality in complex terrain.

Published: December 2019

Objective: This study describes the step-by-step development of the I Mo ve30+ programme and outlines lessons derived from the authors’ experience using an intervention mapping protocol (IMP)-based programme design. The programme was designed to increase the moderate to vigorous physical activity (PA) level at school among Lebanese children, aged 10–12 years. Design: Participatory cross-sectional design including group and individual interviews. Setting: Sidon district of Lebanon. Method: The programme was co-designed with a planning committee and included a local leader in school health, school staff including nurses and members of the target population (schoolchildren). The programme was developed using the six steps of the IMP: elaborating a logic model of the problem, formulating programme objectives, choosing the theoretical methods (i.e. the theory-based techniques used to influence a change objective) and practical applications (i.e. the applied strategies based on those theoretical methods), designing the programme, planning programme implementation, and planning the evaluation. Participants’ involvement in the programme’s activities was entirely voluntary. Results: Implemented by teachers and school nurses, this 14-week school-based programme was designed to provide an additional 30 minutes of school-based PA per day through structural environmental change, educational activities, a PA-monitoring system and PA events at school and in the classroom as well as during recess. Conclusion: IMP enabled the rigorous and systematic development of the programme to improve children’s PA level. The programme description and the lessons learned can facilitate the replication and the scaling up of the programme in other settings.
Posttraumatic stress disorder and complicated grief in bereaved parents of the Sewol Ferry disaster exposed to injustice following the loss
Authors: Choi Hyunjung , Cho Sun-mi 
Published: December 2019

Background: Perceived justice after man-made disaster bereavement may involve as a protective factor in the recovery process. However, perceived justice related to posttraumatic stress disorder (PTSD) or complicated grief (CG) after disaster bereavement has not been sufficiently discussed in previous studies. Aims: This study aims to assess PTSD and CG in bereaved parents of Sewol disaster and to explore whether perceived justice is related with the diagnostic groups. Methods: Bereaved parents of Sewol disaster ( N = 122) were interviewed approximately 2 years after the incident. Structured interviews for PTSD and CG were assessed, and perceived institutional justice surrounding the incident was measured. Symptom groups were identified, and multinomial logistic regression was conducted to find whether perceived justice was related with PTSD or CG. Results: Participants showed high rates of CG and PTSD, and were classified into the both PTSD and CG group, the CG-only group and the resilient group. The analysis revealed that less perceived justice and being a mother increased the likelihood of having both PTSD and CG. Less perceived justice also showed a tendency to be associated with having CG without PTSD. Conclusion: Parents bereaved by the Sewol disaster had high PTSD and CG related to lower levels of perceived justice surrounding the post-disaster period. Post-disaster environment seeking justice may facilitate the natural grieving process or encourage access to effective individual interventions.

Published: December 2019

The Chilean neoliberal state’s institutional strategy for displacing a historical population from Aurora de Chile, a centrally located area with real estate value in the city of Concepción, combined three types of violence: shock urbanization, which used the 2010 earthquake as an opportunity to impose the construction of major infrastructure, the construction of public opinion aimed at naturalizing displacement, and the strategic use of participation as a disciplinary socio-technical device to legitimize a solution to the conflict that guaranteed the building of the Bicentennial Bridge. The deployment of this synergistic, multifaceted violence was a sophisticated management technique associated with a neoliberal urban rationality that contributed to the process of urban renewal. La estrategia institucional del estado neoliberal chileno para desplazar a una población histórica de Aurora de Chile, un barrio céntrico con valor inmobiliario en la ciudad de Concepción, combinó tres tipos de violencia: la urbanización de choque, que utilizó el terremoto de 2010 como una oportunidad para imponer la construcción de infraestructura principal, la construcción de la opinión pública dirigida a naturalizar el desplazamiento, y el uso estratégico de la participación como un dispositivo socio-técnico disciplinario para legitimar una solución al conflicto que garantizó la construcción del Puente Bicentenario. El despliegue de esta violencia sinérgica y multifacética fue una técnica de gestión sofisticada asociada con una racionalidad urbana neoliberal que contribuyó al proceso de renovación urbana.
Stochastic simulation model of water demand in residential buildings
Authors: Ferreira Tiago de VG , Goncalves Orestes M 
Published: December 2019

Over the years, researchers have been conducting studies to investigate the water consumption profile in buildings; these studies have contributed to the accumulation of knowledge regarding the correct sizing of hydraulic systems in buildings. In the context of the methods for the characterization of system demand or loading values, the procedures commonly employed to obtain the project flow rate were primarily proposed in the mid-20th century. These models require revision and adaptation to the current water consumption values. In recent years, certain researchers have proposed simulation models with an application focus on water distribution systems owing to the random and temporal behavior of water demand in this system type. In this study, a water-demand stochastic simulation model in residential buildings is proposed, which encompasses the behavioral modelling of users and their interaction with the system to improve the design process of water distribution systems. Therefore, geographical and population factors (quantity, distribution, and organization) were considered for the behavioral modelling of users; regarding the system modelling, aspects related to the hydraulic system were considered, such as the relation between system components, the type of sanitary appliance, and the number of available devices. Different simulations—with several different types of showers—were conducted using the proposed model. Comparing the flows obtained from the simulation and from the Brazilian standard, for all system components, the decrease in the project flow rate varied from 4% to 61%. In terms of material consumption regarding the pipe (PVC), the decrease varied from 25% to 63%. Practical application: When assessing potential designs for components in water distribution systems in buildings robust information is required for water demand across different time scales. The use of simulation models represents an important advance for the dimensioning process of these components, since it is possible to know a wider range of information about the system demand possibilities. The use of this type of model, as discussed in this article, will equip the designer with an enhanced decision making capacity.

Objective: To investigate the effects of adding stretching to a moderate-intensity aerobic exercise programme in women with fibromyalgia. Design: Randomized controlled trial. Subjects: Sixty-four female patients who were diagnosed with fibromyalgia syndrome based on the American College of Rheumatology criteria were recruited (mean age: 54.27 ± 6.94 years). Interventions: The control group ( n = 32) underwent supervised moderate-intensity cycling (50%–70% of the age-predicted maximum heart rate) three times per week for 12 weeks. The experimental group ( n = 32) underwent the same exercise programme plus a stretching programme once per week for 12 weeks. Main measures: The main measures of this study were sleep quality assessed by the Pittsburgh Sleep Quality Index and the Epworth Sleepiness Scale, the impact of fibromyalgia on quality of life assessed by the Fibromyalgia Impact Questionnaire, and pain perception assessed by the visual analogue scale at baseline, after 4 weeks, and after 12 weeks. Results: The experimental group experienced significant improvements at 4-week measure compared with control group: Pittsburgh Sleep Quality Index ( P < 0.001); Epworth Sleepiness Scale ( P = 0.002); Fibromyalgia Impact Questionnaire (0.93 ± 7.39, P < 0.001); and visual analogue scale (0.52 ± 0.05, P < 0.001). Also at 12-week measure, experimental group experienced significant improvements compared with control group: Pittsburgh Sleep Quality Index ( P < 0.001), Epworth Sleepiness Scale ( P < 0.001); Fibromyalgia Impact Questionnaire (1.15 ± 9.11, P < 0.001); and visual analogue scale (0.81 ± 0.62, P < 0.001). Conclusion: Adding stretching to a moderate-intensity aerobic exercise programme increased sleep quality, decreased the impact of fibromyalgia on the quality of life, and reduced pain compared with just a moderate-intensity aerobic exercise programme in our sample of women with fibromyalgia.

Published: December 2019

Objective: To investigate the validity and test–retest reliability of mHealth devices (Google Fit, Health, STEPZ, Pacer, and Fitbit Ultra) to estimate the number of steps in individuals after chronic stroke and to compare whether the measurement of the number of steps is affected by their location on the body (paretic and non-paretic side). Design: Observational study with repeated measures. Setting: University laboratory. Subjects: Fifty-five community-dwelling individuals with chronic stroke. Intervention: Not applicable. Main measures: The number of steps was measured using mHealth devices (Google Fit, Health, STEPZ, Pacer, and Fitbit Ultra), and compared against criterion-standard measure during the Two-Minute Walk Test using habitual speed. Results: Our sample was 54.5% men, mean age of 62.5 years (SD 14.9) with a chronicity after stroke of 66.8 months (SD 55.9). There was a statistically significant association between the actual number of steps and those estimated by the Google Fit, STEPZ Iphone and Android applications, Pacer iphone and Android, and Fitbit Ultra (0.30 ⩽  r ⩾ 0.80). The Pacer iphone application demonstrated the highest reliability coefficient (ICC(2,1) = 0.80; P < 0.001). There were no statistically significant differences in device measurements that depended on body location. Conclusions: mHealth devices (Pacer–iphone, Fitbit Ultra, Google Fit, and Pacer–Android) are valid and reliable for step counting in chronic stroke survivors. Body location (paretic or non-paretic side) does not affect validity or reliability of the step count metric.

Published: December 2019

Objective Major depressive disorder is associated with abnormal functioning of the hypothalamic–pituitary–adrenal (HPA) axis. Studies using hair cortisol to measure the effect of antidepressants on the HPA axis are lacking. The aim of this study was to explore the long-term effects of antidepressants on hair cortisol concentration (HCC). Methods Participants were 42 patients and 36 healthy individuals. The patients took antidepressants for 4 weeks. Patient HCC was measured pre-treatment and post-treatment. The HCC of healthy controls was also measured. Results Patient post-treatment HCC (mean ± standard deviation: 34.40 ± 32.57 pmol/mg) was significantly higher than patient pre-treatment HCC (17.42 ± 12.40 pmol/mg) and healthy control HCC (10.22 ± 7.99 pmol/mg). No significant correlation was found between Hamilton Depression Rating Scale scores and HCC at pre-treatment or post-treatment. Conclusions Hair cortisol concentration analysis could be used to monitor the dynamics of the effects of antidepressants on the HPA axis.

Published: December 2019

Objectives To investigate the application value of the calcium-suppressed (CaSupp) images of dual-layer detector computed tomography (DLCT) in the evaluation of the temporomandibular joint (TMJ) discs. Methods Thirty-three healthy subjects underwent DLCT and magnetic resonance imaging (MRI) examinations. CaSupp images were reconstructed from the spectral-based images using a calcium suppression algorithm. The location, morphology, and thickness of the posterior band of the TMJ discs were evaluated on the oblique sagittal proton-density weighted images and CaSupp images. Results Of the 66 TMJ discs, anterior displacement was observed on 9 TMJ discs on MR images and 6 TMJ discs on CaSupp images, and posterior displacement was present on 3 TMJ discs on MR and CaSupp images. No significant difference was observed in TMJ disc displacement between MR images and CaSupp images ( P value = 0.730). The TMJ discs without displacement had no significant difference in the thickness of the posterior band between the MR and CaSupp images ( P value = 0.401). Conclusions The calcium-suppressed technique in DLCT may be a simple and preliminary way to evaluate the TMJ disc displacement and structure.

Published: December 2019

Background: While surgery is indicated in Lisfranc fracture-dislocations, the natural history and optimal management of minimally displaced injures are unclear. The aim of this study was to define the rate of subsequent displacement and to determine the clinical outcome after conservative treatment of minimally displaced Lisfranc injuries. Methods: Over a 5-year period (2011-2016), 26 consecutive patients with minimally displaced Lisfranc injuries presenting to a single university teaching hospital were identified retrospectively using hospital electronic records. Patient demographics, injury mechanism, and radiological outcomes were recorded. Patient-reported outcome scores (PROMS) were collated at least 1 year postinjury and included the American Orthopaedic Foot & Ankle Society (AOFAS) midfoot score and Manchester Oxford Foot Questionnaire (MOXFQ). Results: The rate of displacement was 54% (14/26). The median time to displacement was 18 days (range, 2-141 days). Forty-six percent (12/26) of the Lisfranc injuries remained minimally displaced after 12 weeks of conservative treatment. Initial weightbearing status was not associated with the risk of subsequent displacement ( P = .9). At a mean follow-up of 54 months, PROMS were comparable between patients whose injury remained minimally displaced and those that required surgery for further displacement, despite the delay to surgery (AOFAS 78.0 vs 75.9, MOXFQ 24.8 vs 26.3, P > .1). Conclusion: There was a high rate of displacement after initial conservative management of the minimally displaced Lisfranc injuries. Subsequent surgical management of displaced injuries resulted in outcomes comparable to those that remained minimally displaced. Level of Evidence: Level III, retrospective comparative series.

Published: December 2019

Purpose: Light-induced damage to retinal pigment epithelium during pars plana vitrectomy remains a hot topic in ophthalmology. Improvements in technology led to a change of light sources, selective filters, and shorter light exposure time. Currently, there is no satisfying solution to the problem. The aim of the study was to investigate the cytoprotective effects of crocin and resveratrol on light-induced damage to primary human retinal pigment epithelial cells in vitro. Methods: Primary human retinal pigment epithelial cells were exposed to light analogous to the illumination during pars plana vitrectomy. To evaluate the cytoprotective effects and potential toxicity of resveratrol and crocin, human retinal pigment epithelial cells were incubated with varying concentrations of both before 3-[4,5-dimethylthiazol-2-yl] tetrazolium bromide (MTT) viability assay. Furthermore, glutathione levels were measured to investigate synergistic antioxidant potential. Apoptosis of human retinal pigment epithelial cells was determined by a nucleosome detection enzyme-linked immunosorbent assay. Results: Crocin and resveratrol improved cell viability in photodamaged human retinal pigment epithelial cells significantly from 40.65 ± 21.99% in illuminated human retinal pigment epithelial cells and reached a peak viability of 85.64 ± 11.37% in crocin and resveratrol pretreated cells (for all: p < 0.001). In line, the combination of the supplements increased glutathione levels significantly from 39.35 ± 21.96% to 80.74 ± 10.32% ( p = 0.017). No toxic effects were detected ( p > 0.99). However, no change in apoptosis rates could be observed following pretreatment with crocin and resveratrol ( p > 0.99). Conclusion: Crocin and trans-resveratrol revealed cytoprotective effects on human retinal pigment epithelial cells supporting both supplement’s development as potential perioperative treatments in light-induced retinal pigment epithelial damage.

Background Manual segmentations of intracranial hemorrhage on non-contrast CT images are the gold-standard in measuring hematoma growth but are prone to rater variability. Aims We demonstrate that a convex optimization-based interactive segmentation approach can accurately and reliably measure intracranial hemorrhage growth. Methods Baseline and 16-h follow-up head non-contrast CT images of 46 subjects presenting with intracranial hemorrhage were selected randomly from the ANNEXA-4 trial imaging database. Three users semi-automatically segmented intracranial hemorrhage to measure hematoma volume for each timepoint using our proposed method. Segmentation accuracy was quantitatively evaluated compared to manual segmentations by using Dice similarity coefficient, Pearson correlation, and Bland–Altman analysis. Intra- and inter-rater reliability of the Dice similarity coefficient and intracranial hemorrhage volumes and volume change were assessed by the intraclass correlation coefficient and minimum detectable change. Results Among the three users, the mean Dice similarity coefficient, Pearson correlation, and mean difference ranged from 76.79% to 79.76%, 0.970 to 0.980 ( p < 0.001), and −1.5 to −0.4 ml, respectively, for all intracranial hemorrhage segmentations. Inter-rater intraclass correlation coefficients between the three users for Dice similarity coefficient and intracranial hemorrhage volume were 0.846 and 0.962, respectively, and the corresponding minimum detectable change was 2.51 ml. Inter-rater intraclass correlation coefficient for intracranial hemorrhage volume change ranged from 0.915 to 0.958 for each user compared to manual measurements, resulting in an minimum detectable change range of 2.14 to 4.26 ml. Conclusions We spatially and volumetrically validate a novel interactive segmentation method for delineating intracranial hemorrhage on head non-contrast CT images. Good spatial overlap, excellent volume correlation, and good repeatability suggest its usefulness for measuring intracranial hemorrhage volume and volume change on non-contrast CT images.
