This paper presents the results of investigations whose aim was to describe the influence of the pressure difference level on the ability of contaminants migration between neighbouring rooms in dynamic conditions associated with door swing. The analysis was based on airflow visualization made with cold smoke, which simulated the heavy contaminants. The test room was pressurized to a specific level and then the door was opened to observe the trail of the smoke plume in the plane of the door. The door was opened in both directions: to the positively and negatively pressurized room. This study focuses on the visualization of smoke plume discharge and an uncertainty analysis is not applicable. Unlike other studies which focus on the analysis of pressure difference, the present study looks at the contaminants which are heavier than air and on “pumping out” the contaminants by means of door swing. Setting the proper level of pressure difference between the contaminated room and the neighbouring rooms can prove instrumental in ensuring protection against toxic contaminants migration. This study helped to establish the threshold of pressure difference necessary to reduce migration of heavy contaminants to neighbouring rooms.
The implementation of the ‘Removal of the Spare Room Subsidy’ in April 2013, commonly known as the ‘bedroom tax’, affects an estimated 660 000 working age social housing tenants in the UK, reducing weekly incomes by £12-£22. This study aimed to examine the impact of this tax on health and wellbeing in a North East England community in which 68.5% of residents live in social housing.
The indoor biome is a novel habitat which recent studies have shown exhibit not only high microbial diversity, but also high arthropod diversity. Here, we analyze findings from a survey of 50 houses (southeastern USA) within the context of additional survey data concerning house and room features, along with resident behavior, to explore how arthropod diversity and community composition are influenced by physical aspects of rooms and their usage, as well as the lifestyles of human residents. We found that indoor arthropod diversity is strongly influenced by access to the outdoors and carpeted rooms hosted more types of arthropods than non-carpeted rooms. Arthropod communities were similar across most room types, but basements exhibited more unique community compositions. Resident behavior such as house tidiness, pesticide usage, and pet ownership showed no significant influence on arthropod community composition. Arthropod communities across all rooms in houses exhibit trophic structure-with both generalized predators and scavengers included in the most frequently found groups. These findings suggest that indoor arthropods serve as a connection to the outdoors, and that there is still much yet to be discovered about their impact on indoor health and the unique ecological dynamics within our homes.
A positive patient safety climate within teams has been associated with higher safety performance. The aim of this study was to describe and compare attitudes to patient safety among the various professionals in surgical teams in Swedish operating room (OR) departments. A further aim was to study nurse managers in the OR and medical directors' estimations of their staffs' attitudes to patient safety.
Diet-related disease is disproportionately concentrated in low-income communities where fruit and vegetable consumption is far below guidelines. To address financial barriers, Double Up Food Bucks (DUFB)-a statewide healthy food incentive-matches Supplemental Nutrition Assistance Program (SNAP) funds spent at farmers markets. However, incentive use is limited. This study examined the impact of a brief waiting room-based intervention about DUFB on program utilization and produce consumption.
A play and joint attention intervention for teachers of young children with autism: A randomized controlled pilot study

The aim of this study was to pilot test a classroom-based intervention focused on facilitating play and joint attention for young children with autism in self-contained special education classrooms. Thirty-three children with autism between the ages of 3 and 6 years participated in the study with their classroom teachers (n = 14). The 14 preschool special education teachers were randomly assigned to one of three groups: (1) symbolic play then joint attention intervention, (2) joint attention then symbolic intervention, and (3) wait-list control period then further randomized to either group 1 or group 2. In the intervention, teachers participated in eight weekly individualized 1-h sessions with a researcher that emphasized embedding strategies targeting symbolic play and joint attention into their everyday classroom routines and activities. The main child outcome variables of interest were collected through direct classroom observations. Findings indicate that teachers can implement an intervention to significantly improve joint engagement of young children with autism in their classrooms. Furthermore, multilevel analyses showed significant increases in joint attention and symbolic play skills. Thus, these pilot data emphasize the need for further research and implementation of classroom-based interventions targeting play and joint attention skills for young children with autism.

This prospective, observational study characterizes the circumstances that led to falls in long-term care (LTC) residents and describes the characteristics of residents who fractured following a fall. Staff recorded the location of the fall, time of day, activity the participant was doing prior, and if an injury occurred. Descriptive statistics were used to describe the falls, and a generalized linear model was used to determine differences between the circumstances. Of the 101 LTC residents who participated, 41 per cent experienced at least one fall. Residents were significantly more likely to have fallen in the bedroom and while walking. Of the 17 falls resulting in fractures, most occurred in the bedroom and bathroom, during the early morning; most residents who fractured were female with cognitive impairment. To monitor falls comprehensively, ambulatory monitoring that avoids privacy issues in bedrooms or bathrooms may be needed. Interventions should target walking or the bedroom setting.
In research settings, plant-based (vegan) eating plans improve diabetes management, typically reducing weight, glycemia, and low-density lipoprotein (LDL) cholesterol concentrations to a greater extent than has been shown with portion-controlled eating plans.
The beneficial cardiovascular effects of vegetables may be underpinned by their high inorganic nitrate content.

Abstract Introduction: State and federal laws have been enacted to protect the mother’s right to breastfeed and provide breastmilk to her infant. The Patient Protection and Affordable Care Act requires employers to provide hourly waged nursing mothers a private place other than a bathroom, shielded from view, free from intrusion. Minimum requirement for a lactation room would be providing a private space other than a bathroom. Workplace lactation accommodation laws are in place in 24 states, Puerto Rico, and the District of Columbia. These requirements benefit the breast-pumping mother in an office, but what about the breast-pumping mother who travels? Of women with a child under a year, 55.8% are in the workforce. A significant barrier for working mothers to maintain breastfeeding is traveling, and they will need support from the workplace and the community. This study aimed to determine which airports offer the minimum requirements for a breast-pumping mother: private space other than a bathroom, with chair, table, and electrical outlet. Study Design: A phone survey was done with the customer service representative at 100 U.S. airports. Confirmatory follow-up was done via e-mail. Results: Of the respondents, 37% (n=37) reported having designated lactation rooms, 25% (n=25) considered the unisex/family restroom a lactation room, 8% (n=8) offer a space other than a bathroom with an electrical outlet, table, and chair, and 62% (n=62) answered yes to being breastfeeding friendly. Conclusions: Only 8% of the airports surveyed provided the minimum requirements for a lactation room. However 62% stated they were breastfeeding friendly. Airports need to be educated as to the minimum requirements for a lactation room.
