Measure for measure: pack performance versus human dexterity and grip strength

‘Openability’ of food and beverage packaging has been shown to be problematic for older consumers. Pressure on resources has seen the use of packaged food and beverages increase in hospitals within the New South Wales region of Australia. Studies at the University of Wollongong have explored the interaction between older people and the types of packages regularly encountered in the delivery of hospital food and nutrition. As these types of packs are commonly found in UK hospitals as well, a series of studies have been undertaken by the University of Wollongong, Australia, and Sheffield Hallam University, UK, to further evaluate the issues surrounding the ‘openability’ of hospital food and beverage packaging in an attempt to understand in detail the issues leading to difficulty in use. Current methods of pack ‘ease of opening’ evaluation rely on hand strength as the core parameter. Our studies examine the role of dexterity in addition to hand strength in pack opening. Water bottles, single portion drink cartons and cheese portions were among the poorest performing packs. Dexterity, rather than strength is found to be a sensitive and reliable method to understand the issues surrounding the poor pack performance, and a repeatable way of comparing different pack formats is presented

Distribution of coronal and root caries experience among persons aged 60+ in South Australia

The document attached has been archived with permission from the Australian Dental Association. An external link to the publisher’s copy is included.This report provides epidemiological data describing caries experience among the population of non-institutionalized older adults in Adelaide and Mt Gambier. Subjects were selected in a stratified random sample of persons aged 60+ who were listed on the South Australian Electoral Database. Oral examinations were conducted by four calibrated dentists among 853 dentate persons aged 60 years and over. There was an average of 14.7 missing teeth, 8.3 filled teeth and 0.3 decayed teeth, and a further 0.2 teeth were present as retained roots. The mean number of missing teeth was higher (p < 0.05) in older compared with younger age groups, and in Mt Gambier compared with Adelaide. The mean DFS of 22.1 was significantly higher (p < 0.05) among younger persons, females and in Adelaide. Root surface caries affected an average of 3.1 surfaces, and was greater (p < 0.05) among persons aged 70-79 years, males and Adelaide residents. However, when root caries was expressed as an attack rate per 100 exposed surfaces, differences were statistically significant only among age groups. Analysis of specific teeth revealed that no more than 40 per cent of molars were retained, and between 30 and 58 per cent of retained molars had coronal fillings.Gary D. Slade, A. John Spence

Regionalization of pediatric emergency care in Korea

In order to care for an ill or injured child, it is crucial that every emergency department (ED) has a minimum set of personnel and resources because the majority of children are brought to the geographically nearest ED. In addition to adequate preparation for basic pediatric emergency care, a comprehensive, specialized healthcare system should be in place for a critically-ill or injured victim. Regionalization of healthcare means a system providing high-quality and cost-effective care for victims who present with alow frequency, but critical condition, such as multiple trauma or cardiac arrest. Within the pediatric field, neonatal intensive care and pediatric trauma care are good examples of regionalization. For successful regionalized pediatric emergency care, all aspects of a pediatric emergency system, from pre-hospital field to hospital care, should be categorized and coordinated. Efforts to set up the pediatric emergency care regionalization program based on a nationwide healthcare system are urgently needed in Korea

DOs and DON'Ts for using climate change information for water resource planning and management: guidelines for study design

Water managers are actively incorporating climate change information into their long- and short-term planning processes. This is generally seen as a step in the right direction because it supplements traditional methods, providing new insights that can help in planning for a non-stationary climate. However, the continuous evolution of climate change information can make it challenging to use available information appropriately. Advice on how to use the information is not always straightforward and typically requires extended dialogue between information producers and users, which is not always feasible. To help navigate better the ever-changing climate science landscape, this review is organized as a set of nine guidelines for water managers and planners that highlight better practices for incorporating climate change information into water resource planning and management. Each DOs and DON'Ts recommendation is given with context on why certain strategies are preferable and addresses frequently asked questions by exploring past studies and documents that provide guidance, including real-world examples mainly, though not exclusively, from the United States. This paper is intended to provide a foundation that can expand through continued dialogue within and between the climate science and application communities worldwide, a two-way information sharing that can increase the actionable nature of the information produced and promote greater utility and appropriate use

PROMISE: first-trimester progesterone therapy in women with a history of unexplained recurrent miscarriages - a randomised, double-blind, placebo-controlled, international multicentre trial and economic evaluation

BACKGROUND AND OBJECTIVES: Progesterone is essential to maintain a healthy pregnancy. Guidance from the Royal College of Obstetricians and Gynaecologists and a Cochrane review called for a definitive trial to test whether or not progesterone therapy in the first trimester could reduce the risk of miscarriage in women with a history of unexplained recurrent miscarriage (RM). The PROMISE trial was conducted to answer this question. A concurrent cost-effectiveness analysis was conducted. DESIGN AND SETTING: A randomised, double-blind, placebo-controlled, international multicentre study, with economic evaluation, conducted in hospital settings across the UK (36 sites) and in the Netherlands (nine sites). PARTICIPANTS AND INTERVENTIONS: Women with unexplained RM (three or more first-trimester losses), aged between 18 and 39 years at randomisation, conceiving naturally and giving informed consent, received either micronised progesterone (Utrogestan(®), Besins Healthcare) at a dose of 400 mg (two vaginal capsules of 200 mg) or placebo vaginal capsules twice daily, administered vaginally from soon after a positive urinary pregnancy test (and no later than 6 weeks of gestation) until 12 completed weeks of gestation (or earlier if the pregnancy ended before 12 weeks). MAIN OUTCOME MEASURES: Live birth beyond 24 completed weeks of gestation (primary outcome), clinical pregnancy at 6-8 weeks, ongoing pregnancy at 12 weeks, miscarriage, gestation at delivery, neonatal survival at 28 days of life, congenital abnormalities and resource use. METHODS: Participants were randomised after confirmation of pregnancy. Randomisation was performed online via a secure internet facility. Data were collected on four occasions of outcome assessment after randomisation, up to 28 days after birth. RESULTS: A total of 1568 participants were screened for eligibility. Of the 836 women randomised between 2010 and 2013, 404 received progesterone and 432 received placebo. The baseline data (age, body mass index, maternal ethnicity, smoking status and parity) of the participants were comparable in the two arms of the trial. The follow-up rate to primary outcome was 826 out of 836 (98.8%). The live birth rate in the progesterone group was 65.8% (262/398) and in the placebo group it was 63.3% (271/428), giving a relative risk of 1.04 (95% confidence interval 0.94 to 1.15; p = 0.45). There was no evidence of a significant difference between the groups for any of the secondary outcomes. Economic analysis suggested a favourable incremental cost-effectiveness ratio for decision-making but wide confidence intervals indicated a high level of uncertainty in the health benefits. Additional sensitivity analysis suggested the probability that progesterone would fall within the National Institute for Health and Care Excellence's threshold of £20,000-30,000 per quality-adjusted life-year as between 0.7145 and 0.7341. CONCLUSIONS: There is no evidence that first-trimester progesterone therapy improves outcomes in women with a history of unexplained RM. LIMITATIONS: This study did not explore the effect of treatment with other progesterone preparations or treatment during the luteal phase of the menstrual cycle. FUTURE WORK: Future research could explore the efficacy of progesterone supplementation administered during the luteal phase of the menstrual cycle in women attempting natural conception despite a history of RM. TRIAL REGISTRATION: Current Controlled Trials ISRCTN92644181; EudraCT 2009-011208-42; Research Ethics Committee 09/H1208/44.

A transatlantic perspective on 20 emerging issues in biological engineering

Advances in biological engineering are likely to have substantial impacts on global society. To explore these potential impacts we ran a horizon scanning exercise to capture a range of perspectives on the opportunities and risks presented by biological engineering. We first identified 70 potential issues, and then used an iterative process to prioritise 20 issues that we considered to be emerging, to have potential global impact, and to be relatively unknown outside the field of biological engineering. The issues identified may be of interest to researchers, businesses and policy makers in sectors such as health, energy, agriculture and the environment

A call for public archives for biological image data

Public data archives are the backbone of modern biological and biomedical research. While archives for biological molecules and structures are well-established, resources for imaging data do not yet cover the full range of spatial and temporal scales or application domains used by the scientific community. In the last few years, the technical barriers to building such resources have been solved and the first examples of scientific outputs from public image data resources, often through linkage to existing molecular resources, have been published. Using the successes of existing biomolecular resources as a guide, we present the rationale and principles for the construction of image data archives and databases that will be the foundation of the next revolution in biological and biomedical informatics and discovery.Comment: 13 pages, 1 figur
