An IT approach to cardiovascular care based on primary care
We describe a unique telemedicine approach to cardiovascular care, based in primary care, which combines store and forward with real time video. Patients presenting to the family practitioner (GP) with chest pain or symptoms indicative of cardiac disease are assessed within the health centre by exercise test ECG. The report, together with other clinical information is forwarded as an electronic referral to the cardiologist. Suitable candidates for angiography have an initial teleconsultation by video-conferencing, in which not only may the patient, GP and cardiologist discuss the diagnosis and forthcoming procedures in hospital, but also can undertake management of the patient, such as review of medication and life style. Follow-up consultations may be conducted by further tele-clinics. We also show how re-engineering the process has the potential to eliminate 75 of outpatient appointment
Diatom analysis of three Norwegian cores
The purpose of this project is to supply diatom data to the Norwegian Institute of Water Research
for cores from three Norwegian lakes: Steinsfjorden, Lyseren and Gjersjøen. The data will feed into
a palaeolimnological project which also includes analysis of algal pigments and radiometric dating
of the cores.
The study aims to assess shifts in the diatom assemblages and to determine the nature of the
baseline assemblages. Additionally the project aims to apply an existing diatom-phosphorus (P)
transfer function to the diatom data in order to infer the trophic histories of the lakes
Early experiences of the use of remote patient monitoring for the long term management of chronic disease
We describe our experiences of using remote patient monitoring to support the long term management and clinical intervention in patients with chronic disease, such as CHF. Within the project we developed new algorithms to determine from vital signs collected on a daily basis, those patients requiring clinical investigation for their condition. Our aim was for patients to achieve and sustain clinically recommended values for parameters. In our study, the telemonitoring prompted clinical intervention in 37 % of patients. Our approach proved particularly effective for the newly diagnosed, and for those with long term issues of management. 1
The Ontology of Intentional Agency in Light of Neurobiological Determinism: Philosophy Meets Folk Psychology
The moot point of the Western philosophical rhetoric about free will
consists in examining whether the claim of authorship to intentional, deliberative
actions fits into or is undermined by a one-way causal framework of determinism.
Philosophers who think that reconciliation between the two is possible are known as
metaphysical compatibilists. However, there are philosophers populating the other
end of the spectrum, known as the metaphysical libertarians, who maintain that claim
to intentional agency cannot be sustained unless it is assumed that indeterministic
causal processes pervade the action-implementation apparatus employed by the agent.
The metaphysical libertarians differ among themselves on the question of whether the
indeterministic causal relation exists between the series of intentional states and
processes, both conscious and unconscious, and the action, making claim for what has
come to be known as the event-causal view, or between the agent and the action,
arguing that a sort of agent causation is at work. In this paper, I have tried to propose
that certain features of both event-causal and agent-causal libertarian views need to be
combined in order to provide a more defendable compatibilist account accommodating
deliberative actions with deterministic causation. The ‘‘agent-executed-eventcausal
libertarianism’’, the account of agency I have tried to develop here, integrates
certain plausible features of the two competing accounts of libertarianism turning
them into a consistent whole. I hope to show in the process that the integration of these
two variants of libertarianism does not challenge what some accounts of metaphysical
compatibilism propose—that there exists a broader deterministic relation between the
web of mental and extra-mental components constituting the agent’s dispositional
system—the agent’s beliefs, desires, short-term and long-term goals based on them,
the acquired social, cultural and religious beliefs, the general and immediate and
situational environment in which the agent is placed, etc. on the one hand and the
decisions she makes over her lifetime on the basis of these factors. While in the
‘‘Introduction’’ the philosophically assumed anomaly between deterministic causation
and the intentional act of deciding has been briefly surveyed, the second section is
devoted to the task of bridging the gap between compatibilism and libertarianism. The
next section of the paper turns to an analysis of folk-psychological concepts and
intuitions about the effects of neurochemical processes and prior mental events on the
freedom of making choices. How philosophical insights can be beneficially informed
by taking into consideration folk-psychological intuitions has also been discussed,
thus setting up the background for such analysis. It has been suggested in the end that
support for the proposed theory of intentional agency can be found in the folk-psychological intuitions, when they are taken in the right perspective

Temperature effects on zoeal morphometric traits and intraspecific variability in the hairy crab Cancer setosus across latitude
International audiencePhenotypic plasticity is an important but often ignored ability that enables organisms, within species-specific physiological limits, to respond to gradual or sudden extrinsic changes in their environment. In the marine realm, the early ontogeny of decapod crustaceans is among the best known examples to demonstrate a temperature-dependent phenotypic response. Here, we present morphometric results of larvae of the hairy crab , the embryonic development of which took place at different temperatures at two different sites (Antofagasta, 23°45′ S; Puerto Montt, 41°44′ S) along the Chilean Coast. Zoea I larvae from Puerto Montt were significantly larger than those from Antofagasta, when considering embryonic development at the same temperature. Larvae from Puerto Montt reared at 12 and 16°C did not differ morphometrically, but sizes of larvae from Antofagasta kept at 16 and 20°C did, being larger at the colder temperature. Zoea II larvae reared in Antofagasta at three temperatures (16, 20, and 24°C) showed the same pattern, with larger larvae at colder temperatures. Furthermore, larvae reared at 24°C, showed deformations, suggesting that 24°C, which coincides with temperatures found during strong EL Niño events, is indicative of the upper larval thermal tolerance limit. is exposed to a wide temperature range across its distribution range of about 40° of latitude. Phenotypic plasticity in larval offspring does furthermore enable this species to locally respond to the inter-decadal warming induced by El Niño. Morphological plasticity in this species does support previously reported energetic trade-offs with temperature throughout early ontogeny of this species, indicating that plasticity may be a key to a species' success to occupy a wide distribution range and/or to thrive under highly variable habitat conditions
Evaluating regional emission estimates using the TRACE-P observations
Measurements obtained during the NASA Transport and Chemical Evolution over the Pacific (TRACE-P) experiment are used in conjunction with regional modeling analysis to evaluate emission estimates for Asia. A comparison between the modeled values and the observations is one method to evaluate emissions. Based on such analysis it is concluded that the inventory performs well for the light alkanes, CO, ethyne, SO2, and NOₓ. Furthermore, based on model skill in predicting important photochemical species such as O₃, HCHO, OH, HO₂, and HNO₃, it is found that the emissions inventories are of sufficient quality to support preliminary studies of ozone production. These are important finding in light of the fact that emission estimates for many species (such as speciated NMHCs and BC) for this region have only recently been estimated and are highly uncertain. Using a classification of the measurements built upon trajectory analysis, we compare observed species distributions and ratios of species to those modeled and to ratios estimated from the emissions inventory. It is shown that this technique can reconstruct a spatial distribution of propane/benzene that looks remarkably similar to that calculated from the emissions inventory. A major discrepancy between modeled and observed behavior is found in the Yellow Sea, where modeled values are systematically underpredicted. The integrated analysis suggests that this may be related to an underestimation of emissions from the domestic sector. The emission is further tested by comparing observed and measured species ratios in identified megacity plumes. Many of the model derived ratios (e.g., BC/CO, SOₓ/C₂H₂) fall within ∼25% of those observed and all fall outside of a factor of 2.5.

Chlorpromazine for schizophrenia: a Cochrane systematic review of 50 years of randomised controlled trials
BACKGROUND:
Chlorpromazine (CPZ) remains one of the most common drugs used for people with schizophrenia worldwide, and a benchmark against which other treatments can be evaluated. Quantitative reviews are rare; this one evaluates the effects of chlorpromazine in the treatment of schizophrenia in comparison with placebo.
METHODS:
We sought all relevant randomised controlled trials (RCT) comparing chlorpromazine to placebo by electronic and reference searching, and by contacting trial authors and the pharmaceutical industry. Data were extracted from selected trials and, where possible, synthesised and random effects relative risk (RR), the number needed to treat (NNT) and their 95% confidence intervals (CI) calculated.
RESULTS:
Fifty RCTs from 1955–2000 were included with 5276 people randomised to CPZ or placebo. They constitute 2008 person-years spent in trials. Meta-analysis of these trials showed that chlorpromazine promotes a global improvement (n = 1121, 13 RCTs, RR 0.76 CI 0.7 to 0.9, NNT 7 CI 5 to 10), although a considerable placebo response is also seen. People allocated to chlorpromazine tended not to leave trials early in both the short (n = 945, 16 RCTs, RR 0.74 CI 0.5 to 1.1) and medium term (n = 1861, 25 RCTs, RR 0.79 CI 0.6 to 1.1). There were, however, many adverse effects. Chlorpromazine is sedating (n = 1242, 18 RCTs, RR 2.3 CI 1.7 to 3.1, NNH 6 CI 5 to 8), increases a person's chances of experiencing acute movement disorders, Parkinsonism and causes low blood pressure with dizziness and dry mouth.
CONCLUSION:
It is understandable why the World Health Organization (WHO) have endorsed and included chlorpromazine in their list of essential drugs for use in schizophrenia. Low- and middle-income countries may have more complete evidence upon which to base their practice compared with richer nations using recent innovations
Whole population management of patients with diabetes
An increasingly aging population is presenting greater prevalence of people with diabetes, co-morbidities and the complications. Moreover, poor management of diabetes increases risk of complications. There is need to monitor these patients more closely to ensure optimum management. However current management is based on simple clinic based blood pressure and HbA1c readings, which prove insensitive to detect problems of lifestyle and habits. We therefore developed a platform that could be deployed to all diabetes patients to take daily blood pressure and blood glucose measurements that were sent automatically to the clinician. Data was reviewed after a two week monitoring period. Those that were deemed well controlled were asked to return the devices, which were cycled to the next patient. Others were asked to make an appointment with the clinician for review. 37% of patients required intervention. When stratified for risk using parameters from the EPR we found the greatest change in HbA1c in the low risk group, with the high risk group having little change. The greatest problem was denial in the recently diagnosed and lapse in others, resulting in poor adherence to medication and lifestyle
