Summary
Driver fatigue is a major road safety problem that is currently managed by encouraging drivers to take breaks when they feel tired. Unfortunately we dont know whether drivers really are able to detect when they are too tired to drive safely or, if they can make this judgement, whether and what motivates them to stop driving. This research will look at driver awareness of fatigue effects and what indicators and motivators can be used to encourage them to respond to signs of impaired driving.

Summary
Q fever is a severe, sometimes life-threatening infection acquired by individuals who work with livestock, particularly abattoir workers. At least 10% of individuals who develop Q fever experience prolonged ill-health in the form of weeks or months of debilitating fatigue, profuse night sweats, headaches, as well as muscle and joint pains. This poorly understood persistent illness is associated with substantial disability and loss of income.

At least 10% of individuals who develop Q fever experience prolonged ill-health in the form of weeks or months of debilitating fatigue, profuse night sweats, headaches, as well as muscle and joint pains. This poorly understood persistent illness is associated with substantial disability and loss of income. This research is based upon an established cohort study in which subjects with acute, documented Q fever are recruited shortly after the onset of symptoms and followed at regular intervals through to recovery or persistent symptoms. The aim of this research is to determine whether abnormal persistence of the causative organsim of Q fever, Coxiella burnetii, underlies the continued symptoms in those who do not recover promptly from the acute illness. Furthermore, the research is examining the host defense response against the organism via the production of cytokines or immunological hormones, to determine whether these proteins mediate the ongoing symptoms. If confirmed, these hypotheses would lead the way to diagnostic markers for the disorder and a rational treatment strategy.Read moreRead less

The study takes place in western NSW where certain viral illnesses (Glandular Fever, Ross River Virus) and a non-viral infection (QF) are common and have been associated with prolonged fatigue states. The study follows patients from laboratory-documented infections with appropriate infective, immunological and psychological measures throughout the course of their acute illness, the early recovery period and for the next 12 months. These patients are compared with people who present to their doctor with other forms of medically-unexplained fatigue. Very few previous studies have used an appropriate prospective design and followed patients with documented illness from the onset through to the development of specific forms of chronic fatigue. Further, the study is unique in terms of the range of viral and non-viral agents being investigated. It relies on the combined psychiatric, immunological and infective disease expertise of a group of researchers with an international reputation for the successful completion of such multidisciplinary projects. The initial phase of the study has demonstrated that the research team has the capacity to complete this project. Initial results have already demonstrated the potential roles of psychological and immunological factors in causing some cases of prolonged fatigue. Further, the initial results indicate that two key symptom sets (fatigue, psychological distress) can be adequately measured during the recovery phase and are predicted by differing psychological factors. The study will result in the identification of different psychiatric risk factors to chronic fatigue, assist development of clear diagnostic guidelines for post-infective fatigue and guide relevant aetiological and treatment research.Read moreRead less

Methodological barriers include: difficulties in recruitment, high rates of attrition, problems with maintaining distinct and sustainable intervention strategies, poorly chosen outcomes and opposition to randomization. Organizational barriers include: lack of research infrastructure, few trained clinical researchers, prioritisation of clinical responsibilities and funding difficulties. The hierarchy of evidence rates RCTs as the gold standard. An alternative is the n-of-1 trial: a randomized, double-blind cross-over comparison of active drug with placebo or another drug. The patient is in effect their own control. N-of-1 trials provide an objective means of testing the effectiveness of medicines in individual patients, providing evidence stronger than RCT evidence for the efficacy of that drug in that particular individual. If multiple n-of-1 trials are conducted, the resultant data amounts to RCT evidence for that treatment in a population. We propose n-of-1 trials as a workable option for researching the benefit of drugs and other therapies in PC patients. If successful, this model could be accepted internationally as the gold standard for research in this difficult population group. This would be a world first and of great national and international significance. In advanced cancer, the prevalence of fatigue is very high at 60-90% and can be related to the treatment or the disease itself. The impact of fatigue on function (physical, mental, social and spiritual) and hence quality of life (QOL) is very significant for many palliative patients as well as their families-carers. The role of pyschostimulants in the management of fatigue in patients with advanced cancer and life limiting disease needs to be defined. We will conduct n-of-1 trials of psychostimulants (i.e. methylphenidate) for fatigue in a group of 40 patients, recruited from 5 sites around Australia through a national clinical trial network recently set up for palliative care research. Managing fatigue with treatment supported by the best possible evidence for individual patients and producing any improvement in fatigue will improve patients� functional status, and will greatly improve QOL for patients and carers.Read moreRead less

The muscles provide the mechanical power required to move the limbs and the body. To do so, they require energy which is ultimately derived from the breakdown of food. Therefore, we can describe the fundamental process underlying muscular contraction as the conversion of energy from a chemical form into a mechanical form. This project investigates the relationship between the breakdown of molecules that provide energy and the production of mechanical energy or work. Normal contraction involves many cyclic interactions between two proteins, actin and myosin. Each cycle produces a tiny force that contributes to the shortening of the muscle. For over 30 years, it has been thought that energy required for each force producing cycle was provided by the breakdown of one energy-providing molecule, called ATP. Almost all current models of muscle contraction are based on this idea. Recently, data from studies using isolated actin and myosin and observing their interaction in vitro have indicated that many force-producing cycles may be performed with the energy from just one ATP. If this is correct, it will revolutionise our ideas about the way muscles convert chemical energy into mechanical energy. However, the interaction of proteins in a dish is far removed from a normal muscle and the aim of this project is to determine the relationship between force producing cycles and energy use in intact muscles. If multiple force-producing cycles can be powered by one ATP molecule in intact muscle too, then the current idea that the biochemical processes that release energy from ATP are intimately linked to the mechanical changes in myosin that occur as it produces force will be untenable. In short, we will have to rediscover how muscles convert chemical energy into mechanical energy and find out how that energy can be stored from one force-producing cycle to the next.Read moreRead less

During pregnancy and childbirth, women are looking to the complimentary therapies. There is interest in safe and more natural methods to induce labour in women with prolonged pregnancy. Small studies have been undertaken and these show that acupuncture may have a role with inducing labour. However, these studies were small and there is a need for a larger well designed study to see whether acupuncture really does help with inducing labour. This study assesses whether women who have prolonged pregnancy can be successfully induced using acupuncture treatment. Women booked for a medical induction will be offered the opportunity to take part in the trial. Women interested in taking part in the trial will be randomly entered into one of two groups. One group will receive acupuncture and the other group will be given placebo- sham acupuncture. This second group involves the insertion of the needles into areas away from classical acupuncture points. Participation in the trial will take place over a two day period prior to the date of their planned induction. Each treatment will take one hour. Prior to term, focus groups will be held with women examining thier views on the use of acupuncture during pregnancy. All women will be asked to complete a questionnaire after the birth of their baby, this will ask for their views on acupuncture, their expectation and satisfaction from their birthing experience. There is no information to suggest there are any risks or side effects associated with the treatment. In 2001 we expect to report on the effectiveness of this treatment on the induction of labour and maintenance of labour and assessment of whether this treatment meets women's expectations and satisfaction. If the results are positive, it is hoped this will become an option for women requiring an induction of labour.Read moreRead less
