In order to reduce children's exposure to pollutants in classrooms a proper ventilation strategy need to be adopted. Such strategy is even more important in naturally ventilated schools where the air exchange rate is only based on the manual airing of classrooms. The present work aimed to evaluate the effect of the manual airing strategy on indoor air quality in Italian classrooms. For this aim, schools located in the Central Italy were investigated. Indoor air quality was studied in terms of CO2, particle number and PM concentrations and compared to corresponding outdoor levels...

The spatiotemporal variability of ambient volatile organic compounds (VOCs) in Tehran, Iran, is not well understood. Here we present the design, methods, and results of the Tehran Study of Exposure Prediction for Environmental Health Research (Tehran SEPEHR) on ambient concentrations of benzene, toluene, ethylbenzene, p-xylene, m-xylene, o-xylene (BTEX), and total BTEX. To date, this is the largest study of its kind in a low- and middle-income country and one of the largest globally. We measured BTEX concentrations at five reference sites and 174 distributed sites identified by a cluster analytic method...

The unprecedented growth in aviation during the last years has resulted in a notable increase of local air pollution related to airports. The impacts of aviation on air quality can be extremely high particularly around airports serving remote insular regions with pristine atmospheric environments. Here we report measurements that show how the atmospheric aerosol is affected by the activity at a small airport in a remote region. More specifically, we provide measurements performed at the airport of Mytilene, Greece, a regional yet international airport that serves the entire island of Lesvos; the third largest island of the country...

For many donor-conceiving heterosexual parents, the process of deciding whether and what to tell children about their genetic origin is challenging. We hypothesized that incomplete couple agreement about disclosure could be associated with parenting stress. The aim of the study was to investigate (1) parenting stress levels among heterosexual parents of young children following gamete donation and (2) whether parenting stress is related to perceived agreement about disclosure of the donor conception to the children MATERIAL AND METHODS: This study is part of the longitudinal multicenter Swedish Study on Gamete Donation and included a total of 213 heterosexual parents with children age 1-4 years following oocyte donation (n = 103) and sperm donation (n = 110)...

Deep Inspiration Breath-Hold (DIBH) techniques for breast cancer radiation therapy (RT) have reduced cardiac dose compared to Free Breathing (FB). Recently, a voluntary deep inspiration breath-hold (vDIBH) technique was established using in-room lasers and skin tattoos to monitor breath-hold. An in-house quality assessment of positional reproducibility during RT delivery with vDIBH in patients with left-sided breast cancer was evaluated. The electronic portal imaging device (EPID) was used in cinematographic (CINE) mode to capture a sequence of images during beam delivery...

In the last decades, selection for improved prolificacy has resulted in higher litter sizes and has thereby increased the proportion of low birthweight (LW) piglets. It is well documented that LW piglets have lower growth performance, muscle accretion and poor carcass quality. However, little is known about the relations of birthweight with subsequent reproductive performance in gilts. This study investigated the effects of birthweight on reproductive tract and ovarian follicle development in 150-day-old gilts...

Patients' experience of care (PEC) is as an important dimension in quality of care. As a distinct entity from patient satisfaction and patient health-related quality of life, PEC is defined as patients' perceptions of the range of interactions they have with the health care system, including care from providers, facilities, and health plans. While traditionally PEC may be ascertained via informal assessments, in recent years, especially in the United States, there has been a shift towards standardized surveillance of PEC amongst dialysis patients in order to: (1) set a normative expectation regarding the importance of PEC; (2) standardize the components of patients' experience that are assessed to minimize potential "blind spots"; (3) provide a direct "voice" to the patient in communicating perceptions of their care; (4) facilitate comparisons of quality across facilities; and (5) broaden accountability for PEC to the entire multidisciplinary dialysis care team...

The UK has adopted a broader approach to the introduction of Environmental Quality Standard (EQS) for the aquatic environment than many other jurisdictions around the world, with a greater focus on the implementation of scientifically derived standards. This follows the publication of a report by the Royal Commission on Environmental Pollution in 1998 which drew attention to the need to recognise that whilst an EQS is often just viewed as a numerical value, it also has other important characteristics that need to be recognised if it is to be a practical and effective regulatory tool...

A critical goal in the management of elderly patients with diabetes is to improve their health-related quality of life (HRQOL). This study aimed to identify the factors affecting HRQOL in elderly Korean patients with diabetes. Participants were 365 elderly patients with diabetes who were treated in a general hospital in Korea. The data were analysed using independent t-tests, Pearson correlations, and stepwise multiple regression. The mean total HRQOL score was 74.77, and HRQOL showed positive correlations with activities of daily living (ADL), instrumental activities of daily living (IADL), and the Summary of Diabetes Self-care Activities (SDSA)...
