A major factor driving the clean-up of Boston Harbor, MA, USA, induced by the federal Clean Water Act legislation of 1972, was the high prevalence of petroleum and halogenated aromatic hydrocarbon contaminant-associated liver neoplasia in winter flounder Pseudopleuronectes americanus in the harbor in the 1980s. In the present study, we examined the spatial and temporal relationships between the suspended solids and contaminants in the municipal sewage discharge, and liver neoplasia and histopathology in flounder, from 1987 to 2017. Toxics source reduction, sewage treatment, and sludge removal in the 1990s and outfall relocation offshore in 2000 enabled a decreasing prevalence of persistent toxic chemicals in flounder, effluent, and sediment, and consequent disappearance of liver neoplasia and reduction of neoplasm-associated, hydropically vacuolated biliary epithelial cells to background levels. This supports long-term investment in elimination and treatment of anthropogenic waste streams and the value of federal regulatory mandates to maintain and improve regional environmental quality.This work was supported by the Massachusetts Water Resources Authority, Woods Hole Oceanographic Institution, and US Public Health Service (USPHS) grant CA/ES44306

    Buckle up safely: a cluster randomised trial to evaluate the effectiveness of a pre-school based program to increase appropriate use of child restraints

    BACKGROUND: Road traffic crashes for car occupants are a leading cause of death and serious injury in children from high and middle income countries globally. Correct use of appropriate child restraints can significantly reduce death and serious injury but there is a need for well powered trials to examine effectiveness of programs to increase optimal child restraint practices. The aim of this trial is to examine the effectiveness of a comprehensive intervention to increase the use of appropriate child restraints, and decrease incorrect use of child restraints in pre-school aged children traveling in cars. METHODS AND DESIGN: A cluster randomised controlled trial will be conducted, involving 28 pre-school or childcare centres in low income areas of Sydney, Australia, over one calendar year. The intervention is an educational program involving an in-service for centre staff, distribution of educational materials to parents, a parent workshop demonstrating restraint use, subsidised restraints for parents in need, and vouchers for a free restraint checking service. Blinded assessors will observe restraint use at all centres at the end of the calendar year. Data will be analysed on an intention-to-treat basis; the primary analysis will compare the proportion of each of the two outcome measures (use of appropriate restraints, and incorrect use of restraints) at each centre between intervention and control groups. Detailed process evaluation will be conducted, including examination of implementation and utilisation of various elements of the program by both centres and families. DISCUSSION: This assessor blinded cluster randomised trial is powered to provide credible evidence about the efficacy of an education and distribution program in a pre-school setting to increase appropriate use, and decrease incorrect use of child restraints.

    Objective: To conduct a process and impact evaluation of a multifaceted education-based pilot program targeting correct use of age-appropriate restraints in a regional setting with a high proportion of Aboriginal and Torres Strait Islander families. Methods: The program was delivered in 2010 in 3 early learning centers where 31 percent of the children were of Aboriginal and Torres Strait Islander descent. Each component of the program was assessed for message consistency and uptake. To measure program effectiveness, participating children were matched 1:1 by age, language spoken at home, and annual household income with 71 children from the control arm of a contemporaneous trial. The outcome measure in the control and program centers (a 4-category ordinal scale of restraint use) was compared using ordinal logistic regression accounting for age of the parent. Results: Process evaluation found that though program components were delivered with a consistency of message, uptake was affected by turnover of all staff at one center and by parents experiencing difficulty in paying for subsidized restraints at each of the centers. Impact evaluation found that children from the centers receiving the program had nearly twice the odds of being in a better restraint category than children matched from the control group (adjusted odds ratio [ORadj] = 2.06, 95% confidence interval [CI], 1.09-3.90). Conclusions: This was a pragmatic study reflecting the real-life issues of implementing a program in preschools where 57 percent of families had a low income and turnover of staff was high. Despite these issues, impact evaluation showed that the integrated educational program showed promise in increasing correct use of age-appropriate restraints. The findings from this pilot study support the use of an integrated educational program that includes access to subsidized restraints to promote best practice child restraint use among communities that include a high proportion of Aboriginal and Torres Strait Islander families in New South Wales. Future trials in similar settings should consider offering more support in centers with high turnover of staff and offering alternative methods of payment when families experience financial difficulties in purchasing the subsidized restraints. If proven in larger trials, this approach could reduce death and injuries in child passengers in this vulnerable group

    He\u27s the number one thing in my world : Application of the precede-proceed model to explore child car seat use in a regional community in new South Wales

    We explored the factors influencing the use of age-appropriate car seats in a community with a high proportion of Aboriginal families in regional New South Wales. We conducted a survey and three focus groups with parents of children aged 3-5 years enrolled at three early learning centres on the Australian south-east coast. Survey data were triangulated with qualitative data from focus groups and analysed using the PRECEDE-PROCEED conceptual framework. Of the 133 eligible families, 97 (73%) parents completed the survey including 31% of parents who reported their children were Aboriginal. Use of age-appropriate car seats was reported by 80 (83%) of the participants, and awareness of the child car seat legislation was high (91/97, 94%). Children aged 2-3 years were less likely reported to be restrained in an age-appropriate car seat than were older children aged 4-5 years (60% versus 95%: Ļ‡ 2 = 19.14, p \u3c 0.001). Focus group participants highlighted how important their child\u27s safety was to them, spoke of the influence grandparents had on their use of child car seats and voiced mixed views on the value of authorised child car seat fitters. Future programs should include access to affordable car seats and target community members as well as parents with clear, consistent messages highlighting the safety benefits of using age-appropriate car seats

    Older drivers in Australia and advanced vehicle technologies : what are their opinions? : a qualitative study

    Background: There is limited research on older driversā€™ perspectives on advanced vehicle technologies (AVTs). This study investigates what older drivers know and understand about AVTs in the current vehicle market, and identifies what motivates older drivers to use or not use AVTs. Method: Older drivers (ā‰„65 years) living in New South Wales, Australia completed semi-structured telephone interviews guided by the Car Technology Acceptance Model. All interviews were audio-recorded and transcribed verbatim. Content analysis and deductive-inductive thematic analysis were completed on each transcript independently by two researchers, with all themes presented to the investigative team, discussed until consensus was reached. Participant recruitment were ceased after thematic saturation. Results: 24 participants (mean age: 74.5 years; 13 males, 11 females) were interviewed. Eleven different AVTs were mentioned by participants. Attitudes towards these AVTs impacted how much participants understood how these technologies worked. These attitudes and motivation of technology usage could be explained by four major themes; (1) AVTs help with safety but overall responsibility remains with the driver, (2) Lack of clear information and instructions make AVTs look confusing, (3) AVTs need to be more user-friendly for older adults, and (4) Expensive out-of-pocket costs stop AVT usage. Conclusions: Despite understanding the safety benefits of simple, standard AVTs, older drivers perceive barriers that hinder their use of more complicated technologies. Increased consultations to make AVTs more acceptable to older adults are needed. In conjunction, more resources and options aimed at helping older adults better understand and access AVTs need to be developed

    People with age-related macular degeneration (AMD) experience high rates of depression, but rarely engage in or have access to tailored mental wellbeing programmes. This qualitative study investigated the perspectives of those primarily with late AMD on mental health and mental wellbeing programmes. Twenty-eight people with late AMD in at least one eye, and one person with early AMD in both eyes, aged 56-87Ā years (mean age 78Ā years) attending a private eye clinic between December 2019 and January 2020 in Sydney, New South Wales, Australia, participated. Individual semi-structured interviews were conducted and analysed deductively using content analysis, following the individual level factors for health promotion interventions in the behaviour change wheel: Capability (Physical & Psychological), Opportunity (Physical & Social), and Motivation (Reflective & Automatic). Six major themes were identified: Capability: (1) Impact of vision loss on mobility and leisure pursuits; (2) Adjustment to living with vision loss; Opportunity: (3) Program considerations for those with AMD; (4) Stigma and self-perception of vision loss and mental health; Motivation: (5) Accumulation of vision-related issues as a barrier to participation; (6) Examples of others living with vision loss. General personal factors relevant to delivery of a programme in this age group were also identified: Comorbidities; Limitations using technology; Isolation; Financial concerns and Beliefs that undesired effects of aging are inevitable. Complex individual, environmental and social factors influence the perspectives of people with late AMD on mental health, and potential participation in mental wellbeing programmes. These factors should be considered when developing and implementing mental wellbeing programmes to improve the emotional and functional rehabilitation outcomes for people with AMD.

    Associations between vision impairment and driving and the effectiveness of vision-related interventions : protocol for a systematic review and meta-analysis

    Get PDF
    Introduction Driving is one of the main modes of transport with safe driving requiring a combination of visual, cognitive and physical skills. With population ageing, the number of people living with vision impairment is set to increase in the decades ahead. Vision impairment may negatively impact an individual's ability to safely drive. The association between vision impairment and motor vehicle crash involvement or driving participation has yet to be systematically investigated. Further, the evidence for the effectiveness of vision-related interventions aimed at decreasing crashes and driving errors has not been synthesised. Methods and analysis A search will be conducted for relevant studies on Medline (Ovid), EMBASE and Global Health from their inception to March 2020 without date or geographical restrictions. Two investigators will independently screen abstracts and full texts using Covidence software with conflicts resolved by a third investigator. Data extraction will be conducted on all included studies, and their quality assessed to determine the risk of bias using the Joanna Briggs Institute Critical Appraisal Tools. Outcome measures include crash risk, driving cessation and surrogate measures of driving safety (eg, driving errors and performance). The results of this review will be reported using the Preferred Reporting Items for Systematic Review and Meta-Analysis guideline. Meta-analysis will be undertaken for outcomes with sufficient data and reported following the Meta-analyses of Observational Studies in Epidemiology guideline. Where statistical pooling is not feasible or appropriate, narrative summaries will be presented following the Synthesis Without Meta-analysis in systematic reviews guideline. Ethics and dissemination This review will only report on published data thus no ethics approval is required. Results will be included in the Lancet Global Health Commission on Global Eye Health, published in a peer-reviewed journal and presented at relevant conferences.

    A Scoping Review of National Policies for Healthy Ageing in Mainland China from 2016 to 2020

    Get PDF
    Abstract: There remains limited literature to facilitate understanding of healthy ageing-related policies in China over the last five-year policy planning cycle. This study aims to characterise all relevant policies and identifies the policy gaps from a health system perspective. A scoping review framework was used. A thorough search for healthy ageing-related policies was performed on the websites of all government ministries affiliated with the Chinese State Council. Essential information was extracted and mapped to an integrated framework of the World Health Organizationā€™s Health System Building Blocks and the Chi- nese 13 th Five-Year Plan for Healthy Ageing. A total of 12471 policy documents were identified, while 99 policy documents were included. There were 14 ministries involved in the generation of policies, but mul- tisectoral collaboration between the ministries remained limited. National Health Commission and Min- istry of Civil Affairs were the leading ministries. Promoting the integration of medical services and older people care was most frequently addressed within these policies. Applying the health system perspective, governance and financing were often addressed, but there were limited policies on other components of the health system. The findings of this study support four policy recommendations: (1) to enhance mul- tisectoral collaboration in policy development; (2) to strengthen health system building blocks, including healthcare workforce, service delivery, health information, and medical products and technologies; (3) to establish a consolidated policy system centered on the national healthy ageing plan; (4) to formulate a national implementation work plan to promote an integrated health care model for older people
