Objective-The prevalence of obesity is increasing in many European countries and in the United States. This report examines the mortality and morbidity associated with being overweight and obese in the Caerphilly Prospective Study and the relative effects of weight in middle age and self reported weight at 18 years.

Carriage of apoE epsilon 4 lowers the age of onset of Alzheimer's Disease in Northern Ireland

Alzheimer's disease is the most common neurodegenerative disorder affecting those in mid to late adult life. Carriage of an apolipoprotein E (apoE) epsilon 4 allele has been shown to be associated with an increased risk of developing AD in numerous studies involving populations of various races and ethnic backgrounds. It has also been suggested that carriage of this allele reduces the age of onset of AD. To investigate this, we carried out a genetic association study utilising 108 sporadic late-onset AD patients and age, sex and ethnically-matched controls from Northern Ireland. Findings of this study verified the risk of AD associated with carriage of the apoE epsilon 4 allele in a dose-dependent manner (p

Age and sex-related differences in automaticity for mental addition

With age, children process information more rapidly, thus increasing access to and retrieval of information from memory. This speed of information processing is often explained in terms of automaticity. The present study explores this suggestion with respect to primary schoolchildren; 173 pupils aged between 7 and 11 years were tested using a chronometric paradigm. Analysis indicated a highly significant maturational trend towards greater automaticity across all age-groups. However, the results failed to provide evidence for sex differences in automaticity, nor was there evidence of an interaction between age and sex.

The effects of sudden paternal death on young people and their family relationships: some implications for practice

The importance for children and young people to be able to communicate openly about the death of a parent is evident from the literature. This small-scale investigation uses a case-study approach to illustrate the impact on siblings of the sudden death of a father. The abundance of comments from the young people in the study such as “talking is the only thing that helps” and “everybody has to get it out” emphasise the important role of communication within the family. Children tend to take their emotional cues from other family members and, paradoxically, restrict communication of their own grief in an attempt to protect others. Even if painful in the short term, certain lines of communication may need to be established if family members are to be able to support each other in dealing with the distressing experience of the death in a healthy manner. The study suggests that those who work with young people in such circumstances should take cognisance of these issues.

Understanding Old Age and Victimisation: A Critical Exploration

Purpose – The purpose of paper is to shine light on the under-theorised relationship between old age and victmisation. In classical criminological studies, the relationship between “age”, victimisation and crime has been dominated by analysis of younger people's experiences. This paper aims to address this knowledge deficit by exploring older people's experiences by linking it to the social construction of vulnerability.

Design/methodology/approach – The paper explores both historical and contemporary narratives relating to the diverse experiences of older people as victims in the UK. In particular, from 1945 to the present, statistical context and theoretical advancement illuminates that older people as a social group have a deep “fear of crime” to their relative victimisation.

Findings – A careful survey of the criminological literature highlights a paucity of research relating to older people's views and experiences of crime and victimisation. The conceptual issue of vulnerability in different contexts is important in understanding ageing and victimisation in UK. The paper's findings illustrate that their experiences have remained marginalised in the debates around social policy, and how the criminal justice system responds to these changes remains yet to be seen.

Research limitations/implications – Any research attempt at theorising “age” should take into consideration not just younger people, but also the diverse experiences of older people. Policy makers may care to ponder that benchmarks be written that takes into full consideration of older people's experiences as vulnerability.

Practical implications – For criminal justice scholars and practitioners, there is a need to listen to the narratives of older people that should help shape and frame debate about their lived experiences. There should be an examination of existing formal and informal practices regarding elders, as the first step in developing an explicit and integrated set of policies and programmes to address the special needs of this group.

Originality/value – This is an original paper in highlighting how important old age is in construction of “victims” in modern society. By theorising age, victimisation and crime it is hoped to dispel and challenge some of the myths surrounding later life, crime and the older victim.

Revised age estimate of the Mjauvotn tephra A on the Faroe Islands based on Bayesian modelling of C-14 dates from two lake sequences

Tephra horizons are potentially perfect time markers for dating and cross-correlation among diverse Holocene palaeoenvironmental records such as ice cores and marine and terrestrial sequences, but we need to trust their age. Here we present a new age estimate of the Holocene Mjauvotn tephra A using accelerator mass spectrometry C-14 dates from two lakes on the Faroe Islands. With Bayesian age modelling it is dated to 6668-6533 cal. a BP (68.2% confidence interval) - significantly older and better constrained than the previous age.

Palaeobiology of an extinct Ice Age mammal: Stable isotope and cementum analysis of giant deer teeth

The extinct giant deer, Megaloceros giganteus, is among the largest and most famous of the cervids. Megaloceros remains have been uncovered across Europe and western Asia. but the highest concentrations come from Irish bogs and caves Although Megaloceros has enjoyed a great deal of attention over the centuries, paleobiological study has focused oil morphometric and distributional work until now. This paper presents quantitative data that have implications for understanding its sudden extirpation in western Europe during a period of global climate change approximately 10.600 C-14 years ago (ca 12,500 calendar years BP). We report here the first stable isotope analysis of giant deer teeth. which we combine with dental cementum accretion in order to document age, diet and life-history seasonality from birth until death Enamel delta C-13 and delta O-18 measured in the second and third molars from seven individual giant deer Suggest a grass and forbbased diet supplemented with browse in a deteriorating. possibly water-stressed, environment, and a season of birth around spring/early summer Cementurm data indicate that the ages of the specimens ranged from 6.5 to 14 years and that they possessed mature antlers by autumn, similar to extant cervids. In addition. the possibility for combining these two techniques in future mammalian paleoccological studies is considered. The data presented in this study imply that Megoloceros would have indeed been vulnerable to extirpation during the terminal Pleistocene in Ireland. and this information is relevant to understanding the broader pattern of its extinction.

Body Mass Index Is More Predictive of Progenitor Number in Bone Marrow Stromal Cell Population Than Age in Men: Expanding the Predictors of the Progenitor Compartment

Research has focused on in vitro expansion of bone marrow stromal cells with the aim of developing cell-based therapies or tissue-engineered constructs. There is debate over whether there is a reduction in stem cells/osteoprogenitors in the bone marrow compartment with increasing age. The aim of this study was to investigate patient factors that affect the progenitor pool in bone marrow samples. Six milliliters of marrow aspirate was obtained from the femoral canal of 38 primary hip replacement patients (aged 28-91). Outcome measures were total nucleated cell count, colony-forming efficiency, alkaline phosphatase expression, and expression of stem cell markers. There was a nonsignificant negative correlation between age and both colony-forming efficiency and stem cell marker expression. However, body mass index showed a positive, significant correlation with colony area and number in men-accounting for up to 75% of the variation. In conclusion, body mass index, not age, was highly predictive of the number of progenitors found in bone marrow, and this relationship was sex specific. These results may inform the clinician's treatment choice when considering bone marrow-based therapies. Further, it highlights the need to widen research into patient factors that affect the adult stem cell population beyond age and reinforces the need to consider sexes separately.
