Prenatal and early sucking influences on dietary preference in newborn, weaning, and young adult cats

Early experiences are of potential importance in shaping long-term behavior. This study examined the relative influence of prenatal and/or early postnatal experience of chemosensory stimuli on subsequent olfactory and dietary preferences of cats as newborns, at 9-10 weeks, and at 6 months. Cats were exposed to vanillin or 4-ethylguaiacol via their mother's diet either prenatally, postnatally, perinatally (prenatal and postnatal), or experienced no exposure to the stimuli (control). Newborns were given a two-choice olfactory test between the familiar "odor" and no odor; 9-10 week olds were tested for their preference between two food treats, one flavored with the familiar stimulus and the other unflavored; at 6 months, cats were given a choice of two bowls of food, one flavored with the familiar stimulus and the other unflavored. At all ages, cats preferred the familiar, and avoided the unfamiliar, stimulus. Perinatal exposure exerted the strongest influence on preference. Prenatal exposure influenced preference at all ages and postnatal exposure exerted a stronger effect as the cat aged. We conclude that long-term chemosensory and dietary preferences of cats are influenced by prenatal and early (nursing) postnatal experience, supporting a natural and biologically relevant mechanism for the safe transmission of diet from mother to young. © The Author 2012.

Effect of increasing dietary folate on red-cell folate: Implications for prevention of neural tube defects

Background Recommendations by the UK Department of Health suggest that protection from neural tube defects (NTD) can be achieved through intakes of an extra 400 mu g daily of folate/folic acid as natural food, foods fortified with folic acid, or supplements. The assumption is that all three routes of intervention would have equal effects on folate status.

Methods We assessed the effectiveness of these suggested routes of intervention in optimising folate status. 62 women were recruited from the University staff and students to take part in a 3-month intervention study. Participants were randomly assigned to one of the following five groups: folic acid supplement (400 mu g/day; I); folic-acid-fortified foods (an additional 400 mu g/day; II); dietary folate (an additional 400 mu g/day; III); dietary advice (IV), and control (V). Responses to intervention were assessed as changes in red-cell folate between preintervention and postintervention values.

Findings 41 women completed the intervention study. Red-cell folate concentrations increased significantly over the 3 months in the groups taking folic acid supplements (group I) or food fortified with folic acid (group II) only (p<0.01 for both groups). By contrast, although aggressive intervention with dietary folate (group III) or dietary advice (group IV) significantly increased intake of food folate (p<0.001 and p<0.05, respectively), there was no significant change in folate status.

Interpretation We have shown that compared with supplements and fortified food, consumption of extra folate as natural food folate is relatively ineffective at increasing folate status. We believe that advice to women to consume folate-rich foods as a means to optimise folate status is misleading.

Quality of life in screen-detected and typical coeliac disease and the effect of excluding dietary gluten

It is widely recognized that 'asymptomatic' patients with coeliac disease often feel better after commencing a gluten-free diet. The aim of this study was to determine a measure of the quality of life in patients diagnosed as having coeliac disease detected both by screening and those with typical clinical symptoms.

Dietary intake, smoking, and transient anti-gliadin antibodies

The detection of IgA anti-gliadin antibodies in adults can either be helpful in the diagnosis of coeliac disease, be persistent in subjects with normal jejunal mucosa, or occur transiently. We decided to investigate the effects of smoking, alcohol consumption, and dietary intake on the development of IgA anti-gliadin antibodies.

Effectiveness of using clinical guidelines for conducting palliative care family meetings in Japan

PURPOSE: The purpose of this study is to pilot test the effectiveness of using recently developed clinical guidelines from Australia for conducting palliative care family meetings in Japan. METHODS: Palliative care family meetings were conducted using clinical guidelines with 15 primary family carers of cancer patients who were admitted to an acute care hospital in Japan. Using the pre-family meeting questionnaire, the primary carers were asked to write key concerns to discuss during the family meetings and rate their concerns via a numerical rating scale: how upset/worried they were about the problem, frequency in which problem occurs, life interference with the problem, and the confidence to deal with the problem. Within 3 days after the meeting, the primary carers were asked to complete the post-meeting questionnaire to evaluate the effectiveness of the family meeting. RESULTS: There was a significant improvement in family carers' psychological well-being in the post-meeting questionnaires compared to the pre-meeting questionnaires as follows: how upset/worried they were about the problem, t(14)?=?3.1071, p?

Guidelines for the psychosocial and bereavement support of family caregivers of palliative care patients

Support for family caregivers, including bereavement follow-up, is a core function of palliative care. Many caregivers acknowledge positive aspects associated with the role; however a considerable proportion will experience poor psychological, social, financial, spiritual, and physical well-being and some will suffer from complicated grief. Many family caregivers have unmet needs and would like more information, preparation, and support to assist them in the caregiving role. There is a shortage of evidence-based strategies to guide health professionals in providing optimal support while the caregiver is providing care and after the patient's death.
