Tracking leatherback turtles (Dermochelys coriacea) during consecutive inter-nesting intervals: Further support for direct transmitter attachment

Over recent years there have been substantial efforts to record and interpret the post-nesting movements of leatherback turtles (Dermochelys coriacea) breeding in tropical regions. Less well documented are the movements undertaken by individual turtles during the breeding season itself, or more specifically between sequential nesting events. Such movements are of interest for two reasons: (1) gravid female leatherbacks may range extensively into the territorial waters and nesting beaches of neighbouring countries, raising questions for conservationists and population ecologists; and (2) the magnitude of movements themselves help elucidate underlying reproductive strategies (e.g. whether to rest near to the nesting or forage extensively). Here, satellite relay data loggers are used (SRDLs) to detail the movements and behaviour of two female leatherback turtles throughout three consecutive inter-nesting intervals in the Commonwealth of Dominica, West Indies. Both near-shore residence and extensive inter-nesting movements were recorded, contrasting previous studies, with movements away from the nesting beach increasing towards the end of the nesting season. Using this behavioural study as a backdrop, the suitability of attaching satellite transmitters directly to the carapace was additionally explored as an alternative approach to conventional harness deployments. Specifically, the principal aims were to (1) gather empirical data on speed of travel and (2) assess dive performance (aerobic dive limit) to enable comparisons with turtles previously fitted with harnesses elsewhere in the Caribbean (n = 6 turtles; Grenada, WI). This produced mixed results with animals bearing directly attached transmitters travelling significantly faster (55.21 km day(-1): SD 6.68) than harnessed individuals (39.80 km day(-1); SD 6.19); whilst no discernable difference in dive performance could be found between the two groups of study animals.

Diving behaviour during the internesting interval for loggerhead turtles Caretta caretta nesting in Cyprus

Time depth recorders were used to assess the patterns of depth utilisation by 2 loggerhead turtles Caretta caretta in Cyprus, eastern Mediterranean. Dives to the seabed accounted for 59 % (171 h) and 75 % (215 h) of the internesting interval, respectively, with most dives being shallow (

General practitioners' habits and knowledge in relation to the management of H. pylori-associated dyspepsia and their views about a locally available 13-carbon urea breath test

We report the results of general practitioners' views on Helicobacter pylori-associated dyspepsia and use of screening tests in the community. The use of office serology tests in screening is of concern as independent validation in specialist units has been disappointing.

Dietary habits of patients undergoing methadone therapy

OBJECTIVE: This study was designed to record the dietary habits of patients undergoing methadone therapy.

BACKGROUND: Numerous studies report that patients undergoing methadone treatment present with high levels of oral disease, especially dental caries. A number of factors have been described to account for this: sugared methadone preparations, prolonged oral retention, associated xerostomia and poor diet.

METHODS: A cross-sectional descriptive study using survey methodology was conducted of patients attending a non-resident drug rehabilitation clinic. A self-completion questionnaire and diet diary were developed and distributed to 66 patients over an 8 week period.

RESULTS: Of the 66 questionnaires distributed, 52 were successfully completed giving a response rate of 79%. 6 patients declined to complete the questionnaire. The surveyed patient pool consisted of 32 females (62%) and 20 males (38%) with a mean age of 32 years. All the participants were taking a prescribed daily dose of methadone when questioned. 68% of respondents consumed convience foods or sugary snacks every day. Of those patients who drank tea or coffee daily, 84% added sugar and 54% added 3 teaspoons or more. The majority of patients (71%) consumed at least one glass of a fizzy soft drink daily. In addition, the majority of respondents indicated that they snacked regularly between meals and 24% stated that they often woke up during the night for a snack. Patients recorded their last intake of food ranging from 5pm to 3am.

CONCLUSIONS: The patients surveyed had poor dietary habits. Respondents consumed a large amount of convience foods and sugars during mealtimes and through regular snacking. Dietary counselling should be considered as part of treatment for patients undergoing methadone therapy.

Killing Themselves Slowly: India and China's Bad Habits

The world has experienced a public-health miracle in the past half century, as cleaner water, new health technologies, better diet and a host of other improvements have sharply reduced mortality and extended life expectancy in poor countries by as much as 20 years. A substantial portion of those gains has been realized through improvements in infant and child survival. However, the increase in income that was both a cause and effect of this miracle brought with it a new and ironic threat: a steep rise in non-communicable diseases (NCDs) like heart ailments and cancer.

Alcoholic Beverage Preference and Dietary Habits in Elderly across Europe: Analyses within the Consortium on Health and Ageing: Network of Cohorts in Europe and the United States (CHANCES) Project

INTRODUCTION: The differential associations of beer, wine, and spirit consumption on cardiovascular risk found in observational studies may be confounded by diet. We described and compared dietary intake and diet quality according to alcoholic beverage preference in European elderly.

METHODS: From the Consortium on Health and Ageing: Network of Cohorts in Europe and the United States (CHANCES), seven European cohorts were included, i.e. four sub-cohorts from EPIC-Elderly, the SENECA Study, the Zutphen Elderly Study, and the Rotterdam Study. Harmonized data of 29,423 elderly participants from 14 European countries were analyzed. Baseline data on consumption of beer, wine, and spirits, and dietary intake were collected with questionnaires. Diet quality was assessed using the Healthy Diet Indicator (HDI). Intakes and scores across categories of alcoholic beverage preference (beer, wine, spirit, no preference, non-consumers) were adjusted for age, sex, socio-economic status, self-reported prevalent diseases, and lifestyle factors. Cohort-specific mean intakes and scores were calculated as well as weighted means combining all cohorts.

RESULTS: In 5 of 7 cohorts, persons with a wine preference formed the largest group. After multivariate adjustment, persons with a wine preference tended to have a higher HDI score and intake of healthy foods in most cohorts, but differences were small. The weighted estimates of all cohorts combined revealed that non-consumers had the highest fruit and vegetable intake, followed by wine consumers. Non-consumers and persons with no specific preference had a higher HDI score, spirit consumers the lowest. However, overall diet quality as measured by HDI did not differ greatly across alcoholic beverage preference categories.

DISCUSSION: This study using harmonized data from ~30,000 elderly from 14 European countries showed that, after multivariate adjustment, dietary habits and diet quality did not differ greatly according to alcoholic beverage preference.
