The state of the art of paleoparasitological research in the old world

Paleoparasitology in the Old World has mainly concerned the study of latrine sediments and coprolites collected from mummified bodies or archaeological strata, mostly preserved by natural conditions. Human parasites recovered include cestodes, trematodes, and nematodes. The well preserved conditions of helminth eggs allowed paleoepidemiological approaches taking into account the number of eggs found by archaeological stratum. Tentatively, sanitation conditions were assessed for each archaeological period.

Poots launches £18m state-of-the-art Telemonitoring NI service

Health Minister Edwin Poots today marked the roll-out of a ground-breaking hi-tech scheme which will enable more patients to monitor their health in their own homes. Following funding of £18m from the Department of Health, the newly named Centre for Connected Health and Social Care (CCHSC), part of the Public Health Agency, worked in partnership with business consortium TF3to establish the innovative Telemonitoring NI service. The service is now being delivered by the TF3 consortium in partnership with the Health and Social Care Trusts.Remote telemonitoring combines technology and services that enable patients with chronic diseases to test their vital signs such as pulse, blood pressure, body weight, temperature, blood glucose and oxygen levels at home on a daily basis. The service will now be rolled out to 3,500 patients across Northern Ireland per annum for a period of six years.Mr Poots today visited the home of Larne pensioner Michael Howard who has Chronic Pulmonary Obstructive Disorder (COPD) to hear how Telemonitoring NI has changed his life.During the visit Mr Poots said: "Chronic diseases such as heart disease, diabetes and COPD affect around three quarters of people over the age of 75. This is the generation from whom transport and mobility pose the biggest problems. The Telemonitoring NI service will allow thousands to monitor their vital signs without having to leave their own homes."It means that patients are able to understand and manage their condition better. Many say it has improved their confidence and given them peace of mind. With a health professional monitoring each patient's health on a daily basis, there is less need for hospital admission. Carers are also better informed with the pro-active support provided. It means earlier intervention in, and the prevention of, deterioration of condition, acute illness and hospital admissions."Telemonitoring NI is an excellent example of how the Health Service can innovateusing modern technology to deliver a better service for our patients."Eddie Ritson, Programme Director of CCHSC, PHA, said: "The roll-out of Telemonitoring NI represents a significant step towards providing quality care for the growing number of people with heart disease, stroke, some respiratory conditions and diabetes who want to live at home while having their conditions safely managed."This new service will give people more information which combined with timely advice will enable patients to gain more control over their health while supporting them to live independently in their own homes for longer."A patient will take their vital sign measurements at home, usually on a daily basis. and these will automatically be transmited to the Tf3 system. The resulting readings are monitored centrally by a healthcare professional working in the Tf3 triage team. If the patient's readings show signs of deterioration to an unacceptable level, they will be contacted by phone by a nurse working in a central team and if appropriate a healthcare professional in the patient's local Trust will be alerted to enable them to take appropriate action."Families and carers will also benefit from the reassurance that chronic health conditions are being closely monitored on an ongoing basis. The information collected through the service can also be used by doctors, nurses and patients in making decisions on how individual cases should be managed. "Using the service, Mr Howard, 71, who has emphysema - a long-term, progressive disease of the lungs that primarily causes shortness of breath - monitors his vital signs using the new technology every weekday morning. The information is monitored centrally and if readings show signs of deterioration to an unacceptable level, Mr Howard's local healthcare professional is alerted."Taking my readings is such a simple process but one that gives me huge benefits as it is an early warning system to me and also for the specialist nurses in charge of my care. Without the remote telemonitoring I would be running back and forward to the GPs' surgery all the time to have things checked out," he explained."Having my signs monitored by a nurse means any changes in my condition are dealt with immediately and this has prevented me from being admitted to hospital - in the past I've had to spend six days in hospital any time I'm admitted with a chest infection."The telemonitoring is not only reassuring for me, it also gives me more control over managing my own condition and as a result I have less upheaval in my life, and I'm less of a cost to the health care system. Most importantly, it gives me peace of mind and one less thing to worry about at my age."Patients seeking further information about the new telemonitoring service should contact their healthcare professional.

Arrested kinetic Li isotope fractionation at the margin of the llimaussaq complex, South Greenland: Evidence for open-system processes during final cooling of peralkaline igneous rocks

Li contents [Li] and isotopic composition (delta Li-7) of mafic minerals (mainly amphibole and clinopyroxene) from the alkaline to peralkaline Ilimaussaq plutonic complex, South Greenland, track the behavior of Li and its isotopes during magmatic differentiation and final cooling of an alkaline igneous system. [Li] in amphibole increase from < 10 ppm in Caamphiboles of the least differentiated unit to >3000 ppm in Na-amphiboles of the highly evolved units. In contrast, [Li] in clinopyroxene are comparatively low (<85 ppm) and do not vary systematically with differentiation. The distribution of Li between amphibole and pyroxene is controlled by the major element composition of the minerals (Ca-rich and Na-rich, respectively) and changes in oxygen fugacity (due to Li incorporation via coupled substitution with ferric iron) during magmatic differentiation. delta(7) Li values of all minerals span a wide range from + 17 to - 8 parts per thousand, with the different intrusive units of the complex having distinct Li isotopic systematics. Amphiboles, which dominate the Li budget of whole-rocks from the inner part of the complex, have constant delta Li-7 of + 1.8 +/- 2.2 parts per thousand (2 sigma, n = 15). This value reflects a homogeneous melt reservoir and is consistent with their mantle derivation, in agreement with published O and Nd isotopic data. Clinopyroxenes of these samples are consistently lighter, with Delta Li-7(amph-cpx). as large as 8 parts per thousand and are thus not in Li isotope equilibrium. These low values probably reflect late-stage diffusion of Li into clinopyroxene during final cooling of the rocks, thus enriching the clinopyroxene in 6 Li. At the margin of the complex delta(7) Li in the syenites increases systematically, from +2 to high values of + 14 parts per thousand. This, coupled with the observed Li isotope systematics of the granitic country rocks, reflects post-magmatic open-system processes occurring during final cooling of the intrusion. Although the shape and magnitude of the Li isotope and elemental profiles through syenite and country rock are suggestive of diffusion-driven isotope fractionation, they cannot be modeled by one-dimensional diffusive transport and point to circulation of a fluid having a high 67 Li value (possibly seawater) along the chilled contact. In all, this study demonstrates that Li isotopes can be used to identify complex fluid- and diffusion-governed processes taking place during the final cooling of such rocks.
