EU-welfare legislation on pigs

An inventory was performed of 1) the present situation regarding the implementation of Directive 2008/120/EC and 2) national government funded research related to the Directive. Floor design and Group housing of sows are the main themes for both the additional demands to the EU legislation and the national government funded research concerning the minimum standards for the protection of pigs

The role of primary healthcare professionals in oral cancer prevention and detection

AIM: To investigate current knowledge, examination habits and preventive practices of primary healthcare professionals in Scotland, with respect to oral cancer, and to determine any relevant training needs. SETTING: Primary care. METHOD: Questionnaires were sent to a random sample of 357 general medical practitioners (GMPs) and 331 dental practitioners throughout Scotland. Additionally, focus group research and interviews were conducted amongst primary healthcare team members. RESULTS: Whilst 58% of dental respondents reported examining regularly for signs of oral cancer, GMPs examined patients' mouths usually in response to a complaint of soreness. The majority of GMPs (85%) and dentists (63%) indicated that they felt less than confident in detecting oral cancer, with over 70% of GMPs identifying lack of training as an important barrier. Many practitioners were unclear concerning the relative importance of the presence of potentially malignant lesions in the oral cavity. A high proportion of the GMPs indicated that they should have a major role to play in oral cancer detection (66%) but many felt strongly that this should be primarily the remit of the dental team. CONCLUSION: The study revealed a need for continuing education programmes for primary care practitioners in oral cancer-related activities. This should aim to improve diagnostic skills and seek to increase practitioners' participation in preventive activities

Oral and pharyngeal cancer in South Asians and non-South Asians in relation to socioeconomic deprivation in South East England.

From UK Thames Cancer Registry data, after controlling for socioeconomic deprivation of area of residence, South Asian males showed a higher relative risk of oral (1.36; 95% CI: 1.11, 1.67), but not of pharyngeal cancer than non-South Asian males, whereas South Asian females had much higher risks of these cancers (3.67; 95% CI: 2.97, 4.53 and 2.06; 95% CI: 1.44, 2.93), respectively, than non-South Asians

Psychological predictors of 'living well' with dementia: findings from the IDEAL study.

OBJECTIVES:Increasingly, research has explored how psychological resources enable adaptation to illness. However, it is unclear whether psychological resources protect against the potential negative effects on living well with a progressive and life-limiting condition such as dementia. This paper examines the association between psychological resources and the ability to 'live well' with dementia. METHOD:Data from 1547 people with mild-to-moderate dementia in the Improving the experience of Dementia and Enhancing Active Life (IDEAL) cohort were used. Multivariate linear regression was employed to examine the association between self-reported measures of psychological resources (self-efficacy, optimism and self-esteem) and indices of capability to 'live well' (quality of life, well-being and life satisfaction). RESULTS:All three measures of psychological resources had positive and independent associations with indices of living well and the effect sizes were similar. Effect sizes reduced when accounting for shared variance between psychological resources, showing some overlap in these constructs. CONCLUSION:Self-efficacy, optimism and self-esteem were each associated with capability to 'live well'. Overlap between these three resources is evident and when combined they may provide greater resilience when dealing with the challenges of living with dementia. Interventions for people with dementia could seek to improve levels of these potentially-modifiable psychological resources.Economic and Social Research Council (UK) and the National Institute for Health Research (UK

Macro optical projection tomography for large scale 3D imaging of plant structures and gene activity

Optical projection tomography (OPT) is a well-established method for visualising gene activity in plants and animals. However, a limitation of conventional OPT is that the specimen upper size limit precludes its application to larger structures. To address this problem we constructed a macro version called Macro OPT (M-OPT). We apply M-OPT to 3D live imaging of gene activity in growing whole plants and to visualise structural morphology in large optically cleared plant and insect specimens up to 60 mm tall and 45 mm deep. We also show how M-OPT can be used to image gene expression domains in 3D within fixed tissue and to visualise gene activity in 3D in clones of growing young whole Arabidopsis plants. A further application of M-OPT is to visualise plant-insect interactions. Thus M-OPT provides an effective 3D imaging platform that allows the study of gene activity, internal plant structures and plant-insect interactions at a macroscopic scale

Oral cancer awareness amongst hospital nursing staff: a pilot study

<p>Abstract</p> <p>Background</p> <p>Oral cancer is as prevalent as cervical and testicular cancer in the United Kingdom. Nursing staff provide the oral health care for the patient population in hospital. Admission to hospital provides a 'window of opportunity' for oral cancer 'screening' via an oral health check during nursing clerking. This study aimed to investigate whether nursing staff are aware of risk factors for oral cancer, its clinical signs, and could therefore provide a 'screening' service for oral cancer.</p> <p>Method</p> <p>Through the use of a questionnaire we assessed 121 nursing staff on oral health check behaviour and attitudes; their knowledge of risk factors for oral cancer; their understanding of common clinical signs of oral cancer; and their undergraduate and postgraduate training in oral health and oral cancer.</p> <p>Results</p> <p>Over 80% thought oral health checks were important although only 49% performed this task regularly; approximately 70% identified smoking as a risk factor but less than 30% identified alcohol. Awareness of the clinical signs of oral cancer was low with 21% identifying white patches, 15% identifying ulceration and only 2% identifying red patches despite their malignant potential. Nurses within 3 years of qualification were significantly better at recognising risk factors for oral cancer than their colleagues, identifying a need for continuing postgraduate education on oral health and oral cancer. Sixty-one percent of nursing staff received oral healthcare as an undergraduate with 34 percent receiving postgraduate training.</p> <p>Conclusion</p> <p>An oral health check upon admission to hospital provides an opportunity for nurses to 'screen' for oral diseases including oral cancer and allows nurses a greater role in total patient care. Nurses' awareness of oral cancer risk factors and clinical signs was, however, poor. This study highlights a need for improved education of nurses on oral cancer to make the oral health check on admission viable for oral cancer screening.</p

Cross-sectional associations between personality traits and device-based measures of step count and sedentary behaviour in older age: the Lothian Birth Cohort 1936

Background: While the associations between personality traits and self-reported physical activity are well replicated, few studies have examined the associations between personality and device-based measures of both physical activity and sedentary behaviour. Low levels of physical activity and high levels of sedentary behaviour are known risk factors for poorer health outcomes in older age. Methods: We used device-based measures of physical activity and sedentary behaviour recorded over 7 days in 271 79-year-old participants of the Lothian Birth Cohort 1936. Linear regression models were used to assess whether personality traits were cross-sectionally associated with step count, sedentary time, and the number of sit-to-stand transitions. Personality traits were entered one at a time, and all-together, controlling for age and sex in Model 1 and additionally for BMI and limiting long-term illness in Model 2. Results: None of the associations between personality traits and measures of physical activity and sedentary behaviours remained significant after controlling for multiple-comparisons using the False Discovery Rate test (all ps &gt;.07). Conclusions: We found no evidence that personality traits are associated with device-based measures of physical activity or sedentary behaviour in older age. More studies are needed to replicate and examine the nature of these relationships.</p

The impact of comorbidity on the quality of life of people with dementia: findings from the IDEAL study.

Background:The aim was to investigate the comorbidity profile of people with dementia and examine the associations between severity of comorbidity, health-related quality of life (HRQoL) and quality of life (QoL). Methods:The improving the experience of Dementia and Enhancing Active Life (IDEAL) cohort consisted of 1,547 people diagnosed with dementia who provided information on the number and type of comorbid conditions. Participants also provided ratings of their health-related and dementia-specific QoL. Results:The majority of the sample were living with more than one chronic condition. Hypertension was commonly reported and frequently combined with connective tissue disease, diabetes and depression. The number of comorbid conditions was associated with low QoL scores, and those with severe comorbidity (≥5 conditions) showed the greatest impact on their well-being. Conclusions:Comorbidity is an important risk factor for poor QoL and health status in people with dementia. Greater recognition of the nature and impact of comorbidity is needed to inform support and interventions for people with dementia and a multidisciplinary approach to care provision is recommended.Economic and Social Research Council (UK) and the National Institute for Health Research (UK

Prevalence and Subtypes of Mild Cognitive Impairment in Parkinson's Disease.

The current study examined the prevalence and subtypes of Mild Cognitive Impairment (MCI) in an Australian sample of people with Parkinson's Disease (PD). Seventy participants with PD completed neuropsychological assessments of their cognitive performance, using MDS Task Force Level II diagnostic criteria for PD-MCI. A cut-off score of less than one standard deviation (SD) below normative data determined impaired performance on a neuropsychological test. Of 70 participants, 45 (64%) met Level II diagnostic criteria for PD-MCI. Among those with PD-MCI, 42 (93%) were identified as having multiple domain impairment (28 as amnestic multiple domain and 14 as nonamnestic multiple domain). Single domain impairment was less frequent (2 amnestic/1 nonamnestic). Significant differences were found between the PD-MCI and Normal Cognition groups, across all cognitive domains. Multiple domain cognitive impairment was more frequent than single domain impairment in an Australian sample of people with PD. However, PD-MCI is heterogeneous and current prevalence and subtyping statistics may be an artifact of variable application methods of the criteria (e.g., cut off scores and number of tests). Future longitudinal studies refining the criteria will assist with subtyping the progression of PD-MCI, while identifying individuals who may benefit from pharmacological and nonpharmacological interventions

Elastic and inelastic light scattering from single bacterial spores in an optical trap allows the monitoring of spore germination dynamics

Raman scattering spectroscopy and elastic light scattering intensity (ESLI) were used to simultaneously measure levels of Ca-dipicolinic acid (CaDPA) and changes in spore morphology and refractive index during germination of individual B. subtilis spores with and without the two redundant enzymes (CLEs), CwlJ and SleB, that degrade sporesâ peptidoglycan cortex. Conclusions from these measurements include: 1) CaDPA release from individual wild-type germinating spores was biphasic; in a first heterogeneous slow phase, Tlag, CaDPA levels decreased â ¼15% and in the second phase ending at Trelease, remaining CaDPA was released rapidly; 2) in L-alanine germination of wild-type spores and spores lacking SleB: a) the ESLI rose â ¼2-fold shortly before Tlag at T1; b) following Tlag, the ESLI again rose â ¼2-fold at T2 when CaDPA levels had decreased â ¼50%; and c) the ESLI reached its maximum value at â ¼Trelease and then decreased; 3) in CaDPA germination of wild-type spores: a) Tlag increased and the first increase in ESLI occurred well before Tlag, consistent with different pathways for CaDPA and L-alanine germination; b) at Trelease the ESLI again reached its maximum value; 4) in L-alanine germination of spores lacking both CLEs and unable to degrade their cortex, the time Î Trelease (Treleaseâ Tlag) for excretion of â ¥75% of CaDPA was â ¼15-fold higher than that for wild-type or sleB spores; and 5) spores lacking only CwlJ exhibited a similar, but not identical ESLI pattern during L-alanine germination to that seen with cwlJ sleB spores, and the high value for Î Trelease.
