Materials and articles intended to come into contact with food must be shown to be safe because they might interact with food during processing, storage and the transportation of foodstuffs. Framework Directive 89/109/EEC and its related specific Directives provide this safety basis for the protection of the consumer against inadmissible chemical contamination from food-contact materials. Recently, the European Commission charged an international group of experts to demonstrate that migration modelling can be regarded as a valid and reliable tool to calculate 'reasonable worst-case' migration rates from the most important food-contact plastics into the European Union official food simulants. The paper summarizes the main steps followed to build up and validate a migration estimation model that can be used, for a series of plastic food-contact materials and migrants, for regulatory purposes. Analytical solutions of the diffusion equation in conjunction with an 'upper limit' equation for the migrant diffusion coefficient, D P , and the use of 'worst case' partitioning coefficients K P,F were used in the migration model. The results obtained were then validated, at a confidence level of 95%, by comparison with the available experimental evidence. The successful accomplishment of the goals of this project is reflected by the fact that in Directive 2002/72/EC, the European Commission included the mathematical modelling as an alternative tool to determine migration rates for compliance purposes.

The group music intervention is a noninvasive and inexpensive therapy that appeared to reduce elders' depression. It also delayed the deterioration of cognitive functions, particularly short-term recall function. Group music therapy may be an appropriate intervention among elderly persons with mild and moderate dementia.

Lowe G., Plummer V., O’Brien A.P. & Boyd L. (2012) Time to clarify – the value of advanced practice nursing roles in health care. Journal of Advanced Nursing68(3), 677–685. Abstract Aim.  This article presents a discussion of the importance of providing meaningful advanced practice nursing role definition and clarity to improve international standards of nursing titles and scopes of practice. Background.  A plethora of international literature exists discussing advanced practice nursing roles and their contribution to healthcare delivery in various countries. However, lack of consistency around title, role definition and scope of practice remains. Data sources.  CINAHL and Medline databases were searched using ‘nurse practitioner’, ‘nurse practitioner role’, ‘nurse practitioner practice’, ‘nurse practitioner in public health’, ‘advanced practice nursing roles’ and ‘development of new nursing roles’ with articles limited to years 1995–2010. Citations used in those articles were also explored. All cited articles were in the English language. Discussion.  This article supports the need to strengthen the Nurse Practitioner role in health care and professional clarity is identified as a strategy to enhance this. Themes around role clarity, professional identity, ability to enhance healthcare provision and inter‐professional issues are examined. The need to more clearly articulate advanced nursing roles in light of the evolution of the Nurse Practitioner role is highlighted. Much work has already occurred in this domain and a means of adapting and broadening these developments for a wider, more global audience whilst maintaining local context is discussed. Conclusion.  Although evidence exists that advanced practice nursing roles are increasing internationally, uncertainty around role clarity remains. This is problematic because the valuable contribution of nursing roles is lost, if the ability to clearly express their function does not exist.

Meeting Intensive Care Unit family needs can be achieved by supporting and involving families in the care of the critically ill family member. More emphasis should be placed on identifying the family needs in relation to the influence of cultural values and religion held by the family members and the organisational climate and culture of the working area in the Intensive Care Unit.

More than 10% of fathers experience depression and anxiety during the perinatal period, but paternal perinatal depression (PPND) and anxiety have received less attention than maternal perinatal mental health problems. Few mainstream treatment options are available for men with PPND and anxiety. The aim of this literature review was to summarize the current understanding of PPND and the treatment programs specifically designed for fathers with perinatal depression. Eight electronic databases were searched using a predefined strategy, and reference lists were also hand searched. PPND and anxiety were identified to have a negative impact on family relationships, as well as the health of mothers and children. Evidence suggests a lack of support and tailored treatment options for men having trouble adjusting to the transition to fatherhood. Of the limited options available, cognitive behavioral therapy, group work, and blended delivery programs, including e-support approaches appear to be most effective in helping fathers with perinatal depression and anxiety. The review findings have important implications for the understanding of PPND and anxiety. Future research is needed to address the adoption of father-inclusive and father-specific models of care to encourage fathers’ help-seeking behavior. Inclusion of male-specific requirements into support and treatment options can improve the ability of services to engage new fathers. Psychotherapeutic intervention could assist to address the cognitive differences and dissonance for men adjusting to the role of father, including male identity and role expectations.

This integrative review aimed to identify and synthesize evidence on workplace stress and resilience in the Australian nursing workforce. A search of the published literature was conducted using EMBASE, MEDLINE, CINAHL (EBSCO), PsycINFO, Web of Science, and Scopus. The search was limited to papers published in English from January 2008 to December 2018. The review integrated both qualitative and quantitative data into a single synthesis. Of the 41 papers that met the inclusion criteria, 65.85% (27/41) used quantitative data, 29.26% (12/41) used qualitative data, and 4.87% (2/41) used mixed methods. About 48.78% (20/41) of the papers addressed resilience issues, 46.34% (19/41) addressed workplace stress, and 4.87% (2/41) addressed both workplace stress and resilience. The synthesis indicated that nurses experience moderate to high levels of stress. Several individual attributes and organizational resources are employed by nurses to manage workplace adversity. The individual attributes include the use of work–life balance and organizing work as a mindful strategy, as well as self‐reliance, passion and interest, positive thinking, and emotional intelligence as self‐efficacy mechanisms. The organizational resources used to build resilience are support services (both formal and informal), leadership, and role modelling. The empirical studies on resilience largely address individual attributes and organizational resources used to build resilience, with relatively few studies focusing on workplace interventions. Our review recommends that research attention be devoted to educational interventions to achieve sustainable improvements in the mental health and wellbeing of nurses.

Disturbed circadian rhythm in humans has been associated with a variety of mental and physical disorders and may negatively impact on work safety, performance, and productivity.

IntroductionThe importance of accessible mental health treatment is a global concern, particularly when one in five people will experience a mental health problem in their lifespan. This is no less important in Ghana; however, no studies have yet attempted to appraise and synthesise the potential enablers and barriers to accessing services in Ghana. The aim of this integrative review is therefore to identify and synthesise existing evidence on the barriers and enablers to accessing mental health services in Ghana.MethodsA search of the published literature was conducted using Medline, EMBASE, PsycINFO, CINAHL (EBSCO), Web of Science, and Scopus electronic databases. The search was limited to papers published in English and within 2000–2018. Using pre-defined inclusion and exclusion criteria, two reviewers independently screened the titles and abstracts of the retrieved papers. A data extraction form and a Critical Appraisal Checklist were used to extract and appraise data, respectively. The integrative review incorporates both qualitative and quantitative data into a single synthesis.ResultsOut of 42 papers that met the inclusion criteria, 50% used qualitative methods, 33.3% used mixed methods and 16.7% used quantitative methods alone. The potential barriers in accessing mental health services were attitudinal, knowledge about services, treatment cost, transportation and geographical proximity, as well as perceived efficacy of medication. Similarly, the health systems factors contributing to barriers were low priority, limited funding sources, irregular medicine supply, limited services for marginalised groups and poor state of psychiatric facilities, together with poor management of mental health cadres. The potential enablers for service users involved increased decentralisation and integration, task-shifting and existing support services.ConclusionThe existing evidence on mental health in Ghana is skewed towards weaknesses in the systems and stigma, with rationally little, or no, evidence or emphasis on the effectiveness, or quality of mental health services. These attributes largely neglect the provision of psychiatric services for marginalised mental health service user groups, including children, adolescents, people with disabilities and the elderly.Electronic supplementary materialThe online version of this article (10.1186/s12961-018-0382-1) contains supplementary material, which is available to authorized users.
