International study of objectively measured physical activity and sedentary time with body mass index and obesity: IPEN adult study

BACKGROUND: Physical activity (PA) has been consistently implicated in the etiology of obesity, whereas recent evidence on the importance of sedentary time remains inconsistent. Understanding of dose-response associations of PA and sedentary time with overweight and obesity in adults can be improved with large-scale studies using objective measures of PA and sedentary time. The purpose of this study was to examine the strength, direction and shape of dose-response associations of accelerometer-based PA and sedentary time with body mass index (BMI) and weight status in 10 countries, and the moderating effects of study site and gender. METHODS: Data from the International Physical activity and the Environment Network (IPEN) Adult study were used. IPEN Adult is an observational multi-country cross-sectional study, and 12 sites in 10 countries are included. Participants wore an accelerometer for seven consecutive days, completed a socio-demographic questionnaire and reported height and weight. In total, 5712 adults (18-65 years) were included in the analyses. Generalized additive mixed models, conducted in R, were used to estimate the strength and shape of the associations. RESULTS: A curvilinear relationship of accelerometer-based moderate-to-vigorous PA and total counts per minute with BMI and the probability of being overweight/obese was identified. The associations were negative, but weakened at higher levels of moderate-to-vigorous PA (>50 min per day) and higher counts per minute. No associations between sedentary time and weight outcomes were found. Complex site- and gender-specific findings were revealed for BMI, but not for weight status. CONCLUSIONS: On the basis of these results, the current Institute of Medicine recommendation of 60 min per day of moderate-to-vigorous PA to prevent weight gain in normal-weight adults was supported. No relationship between sedentary time and the weight outcomes was present, calling for further examination. If moderator findings are confirmed, the relationship between PA and BMI may be country- and gender-dependent, which could have important implications for country-specific health guidelines. © 2015 Macmillan Publishers Limited All rights reserved.

How does the cookie crumble? legal costs under a uniform interpretation of the United Nations Convention on Contracts for the International Sale of Goods

A family owned Mexican company, Zapata Hermanos Sucesores, S.A. ("Zapata"), sold approximately US$950,000 worth of cookie tins over a period of four years to the Maurice Lenell Cooky Company ("Lenell"), an American company that produced baked goods. Lenell failed to pay Zapata for the cookie tins so Zapata sought legal advice and instituted legal proceedings against Lenell for breach of contract in the Federal District Court of Illinios. The cookie tin sale contracts were governed by the United Nations Convention on Contracts for the International Sale of Goods ("CISG"). Zapata succeeded in its Federal District Court claim and, as part of the Court's order, was awarded US$550,000 as foreseeable loss under Article 74 of the CISG, being the amount of legal fees incurred by Zapata in bringing proceedings against Lenell. On appeal to the Federal Appellate Court, however, the award of legal fees was overturned. The parties now find themselves contesting a leave application to appeal to the Supreme Court of the United States of America in a much anticipated debate over who should pay the lawyers.

Harmonisation and the United Nations Convention on Contracts for the International Sale of Goods

After many years of negotiation, the United Nations Convention on Contracts for the International Sale of Goods (“CISG”) came into force in 1988. Today, 62 states have adopted the CISG. Together these countries account for over two-thirds of all world trade.2 On this basis alone, the CISG is an outstanding success in the legal harmonisation of the law governing the international sale of goods. However, the CISG has its critics and much comment has been made on the failure of the CISG to achieve its goal of promoting international trade through a body of uniform rules.The primary motivation driving the push for a harmonised law on the international sale of goods is economic: a harmonised law makes it easier and more efficient for the business person to sell and buy goods across state borders. However, the engine driving the push for harmonisation is political and cultural; and the task of creating the harmonised law belongs to the diplomat.3 A study of the CISG demonstrates that the political and cultural demands on the diplomat also act as shackles that restrain the achievement of a harmonised law.This paper will consider the CISG and discuss the constraints on treaty making as a mechanism for legal harmonisation. Part one discusses the constraints faced when creating a uniform text.Part two discusses the problems with the text of the CISG that result from the negotiation process. Finally, part three discusses the constraints faced in maintaining the uniformity of the CISG.

International study of perceived neighbourhood environmental attributes and Body Mass Index: IPEN Adult study in 12 countries

BACKGROUND: Ecological models of health behaviour are an important conceptual framework to address the multiple correlates of obesity. Several single-country studies previously examined the relationship between the built environment and obesity in adults, but results are very diverse. An important reason for these mixed results is the limited variability in built environments in these single-country studies. Therefore, the aim of this study was to examine associations between perceived neighbourhood built environmental attributes and BMI/weight status in a multi-country study including 12 environmentally and culturally diverse countries. METHODS: A multi-site cross-sectional study was conducted in 17 cities (study sites) across 12 countries (Australia, Belgium, Brazil, China, Colombia, Czech Republic, Denmark, Mexico, New Zealand, Spain, the UK and USA). Participants (n = 14222, 18-66 years) self-reported perceived neighbourhood environmental attributes. Height and weight were self-reported in eight countries, and measured in person in four countries. RESULTS: Three environmental attributes were associated with BMI or weight status in pooled data from 12 countries. Safety from traffic was the most robust correlate, suggesting that creating safe routes for walking/cycling by reducing the speed and volume of traffic might have a positive impact upon weight status/BMI across various geographical locations. Close proximity to several local destinations was associated with BMI across all countries, suggesting compact neighbourhoods with more places to walk related to lower BMI. Safety from crime showed a curvilinear relationship with BMI, with especially poor crime safety being related to higher BMI. CONCLUSIONS: Environmental interventions involving these three attributes appear to have international relevance and focusing on these might have implications for tackling overweight/obesity.

Ongoing challenges responding to behavioural and psychological symptoms of dementia

BACKGROUND: Mid- to late-stage dementia is often characterized by behavioural and psychological symptoms, including, but not limited to physical and verbal aggression. INTRODUCTION: Although there is a considerable research about the prevalence, aetiology, and management of behavioural and psychological symptoms of dementia, there is limited research about the experience of caring for people with such symptoms in long-term aged care facilities. AIM: The aims of the study were to describe: (i) nurses' experiences of caring for people with behavioural and psychological symptoms of dementia in long-term aged care facilities, and (ii) strategies nurses used to deal with these symptoms. METHODS: A qualitative exploratory and descriptive design, involving focus group interviews with 30 nurses from three long-term aged care units in Australia. The transcripts were analysed using inductive content analysis. RESULTS: The findings revealed five interrelated themes: (i) working under difficult conditions, (ii) behavioural and psychological symptoms of dementia: an everyday encounter, (iii) making sense of behavioural and psychological symptoms of dementia, (iv) attempting to manage behavioural and psychological symptoms of dementia, and (v) feeling undervalued. CONCLUSION: This study highlighted the difficult conditions under which nurses worked and the complexity of caring for individuals who have behavioural and psychological symptoms of dementia. IMPLICATIONS FOR NURSING AND HEALTH POLICY: Organizational efforts to enhance the quality of care for individuals with behavioural and psychological symptoms of dementia in long-term aged care facilities should extend beyond staff education to heed nurses' concerns about organizational barriers to interpersonal care.

The construction of a subset of ICNP® for patients with dementia: a Delphi consensus and a group interview study

BACKGROUND: The International Classification for Nursing Practice (ICNP®) 2013 includes over 4000 concepts for global nursing diagnoses, outcomes and interventions and is a large and complex set of standardised nursing concepts and expressions. Nurses may use subsets from the ICNP as concepts and expressions for research, education and clinical practice. The objective of this study was to identify and validate concepts for an ICNP subset to guide observations and documentation of nursing care for patients with dementia.

METHOD: The process model for developing ICNP subsets was followed, according to the guidelines adopted by the International Council of Nursing (ICN). To identify relevant and useful concepts for the subset, a modified form of the Delphi method was used. Six nurses working in healthcare services in three municipalities in Norway with postgraduate education in geriatric psychiatry and dementia care participated in two Delphi sessions. The participants reviewed and scored the concepts included in the suggested subset and had an opportunity to rewrite them and offer alternatives. To validate the subset after the Delphi study, a group interview was conducted with six other nurses with postgraduate education in geriatric psychiatry and dementia care. The group interview was recorded and transcribed, and summative content analysis was used.

RESULTS: Suitable concepts for an ICNP subset to guide observations and documentation of nursing care for patients with dementia were identified. In total, 301 concepts were identified, including 77 nursing diagnoses, 78 outcomes and 146 nursing interventions. An increased focus on concepts to describe basic psychosocial needs such as identity, comfort, connection, inclusion and engagement was recommended by nurses in the validation process.

CONCLUSIONS: Relevant and pre-formulated nursing diagnoses, goals and interventions were identified, which can be used to develop care plans and facilitate accuracy in the documentation of individuals with dementia. The participants believed that it may be difficult to find formulations for all steps of the nursing process. In particular, nursing diagnoses and psychosocial needs are often inadequately documented. The participants highlighted the need for the subset to contain essential information about psychosocial needs and communication.
