Summary
Standard advice in the clinical management of headaches is to counsel headache sufferers to avoid any factors that could trigger a headache. There is a compelling logic to this approach but is there a danger that it amounts to being over-protective in the sense that it encourages headache sufferers to 'cocoon' themselves from situations that could give rise to headaches, ultimately resulting in them losing their ability to cope with such situations.

There is a compelling logic to this approach but is there a danger that it amounts to being over-protective in the sense that it encourages headache sufferers to 'cocoon' themselves from situations that could give rise to headaches, ultimately resulting in them losing their ability to cope with such situations. Certainly, avoiding situations that elicit anxiety leads to a sensitisation process whereby the situations elicit greater anxiety. And the converse is true, exposure to anxiety-eliciting situations results in a desensitisation process whereby the situations elicit less anxiety. Whether avoidance or exposure is more appropriate in the management of headache disorders depends on the processes by which sensitivity to trigger factors is gained and lost. Two studies will be completed that test different models of these processes. The expected outcome of these studies is that they will support the theory that stimuli acquire the capacity to elicit headaches as a function of individuals trying to avoid or escape from any factor that they believe could trigger a headache. This sensitisation process can be reversed by prolonged exposure to headache trigger factors. Such results would suggest that the established practice of counselling headache sufferers to avoid triggers is counterproductive as it may lead to a reduction of headaches in the short-term but may also lead to an insidious sensitisation process that ultimately results in an increase in headaches. Given that headaches are so common and associated with such high direct and indirect costs, changes in clinical management arising from these findings could have major benefits to individuals, families and society.Read moreRead less
Improving Behavioural Treatment For Frequent Headaches By Incorporating A New Approach To Managing Triggers

Summary
The standard clinical advice is that the best way to prevent headaches is to avoid the triggers, but we have argued that this may lead to decreased tolerance for triggers and therefore more headaches. We have developed an innovative approach to managing triggers which focuses on training people to cope with triggers. The proposed research will evaluate a new treatment for headaches based on integrating our approach to managing triggers into our behavioural treatment program for headaches.
Combined Electroacupuncture And Cognitive Behavioural Therapy For Tension-type Headache: A Randomised Controlled Trial

Summary
Tension-type headache (TTH) affects many and the direct and indirect costs are significant. Medications are either not effective long-term or have side-effects. Acupuncture and Cognitive behavioural therapy (CBT) are effective and safe treatments. The combination of acupuncture and CBT could provide a better outcome. We will undertake a rigorous clinical study to evaluate this. This is the first examination of the combination, and will be of significant value to patients and to clinicians.
HPV-based Testing And Treatment For The Elimination Of Cervical Cancer In Papua New Guinea (HPVTATE)

Summary
Building on the innovative cervical screening model that we successfully designed and delivered in partnership with provincial health authorities in urban primary care settings in PNG, the overarching aim of the proposed study is to determine the reach, effectiveness, cost-effectiveness, acceptability and scalability of HPV-based testing and treatment for the elimination of cervical cancer (HPVTATE) among women in rural and remote communities in Papua New Guinea.

Summary
Cervical cancer remains common globally despite over 50 years of Pap testing. Australia led the world in HPV vaccination and in 2017 will be the first to deliver a national screening program based on HPV testing. Our CRE, led by cervical cancer prevention experts at CCNSW,VCS, and Kirby, will marry cross-disciplinary research and evaluation of HPV vaccination and screening to provide solid evidence about these new approaches with a view to ultimately reducing the global burden of this cancer.
Trigeminal pain includes such disorders as headache, migraine, trigeminal neuralgia, dental and temporomandibular joint pain. These disorders affect more than 10 % of the population and many of the afflicted get only partial relief from current treatments. Trigeminal pain is conveyed from the head to the brain via primary afferent nerves.

These disorders affect more than 10 % of the population and many of the afflicted get only partial relief from current treatments. Trigeminal pain is conveyed from the head to the brain via primary afferent nerves. Work in the current proposal focuses on transmission of information in the brainstem as well as in the primary afferent nerves. Previously our group has reported that adenosine- 5' triphosphate (ATP) causes an increase in excitatory neurotransmission from primary afferent nerves; such an increase has been reported to be painful in previous human and animal studies. Recently we have shown that the ATP induced increase in neurotransmission is dependant on activation of a specific excitatory receptor, the N-methyl D aspartate (NMDA) receptor, which has been widely implicated in other brain functions such as memory, and in disorders such as neuron death following stroke. The chief investigators involved in this application plan to study the role of the ATP receptor and the interaction with NMDA receptors in an inflammatory trigeminal pain model. Electrophysiological, pharmacological and immunohistochemical studies will be performed in order to address the aims of this proposal. A greater understanding of how these receptors modulate neurotransmission in pain pathways will lead to a greater understanding of trigeminal pain and the potential development of new therapeutics.Read moreRead less
The Population Impact Of Human Papillomavirus Vaccination On Circulating Genotypes

Summary
Infection with human papillomavirus (HPV) is very common. Persistent infection can cause abnormal changes to cervical cells as found on Pap smears and if untreated, over time can develop into cervical cancer. Recently, a vaccine was introduced in Australia for women aged 12-26. To monitor the effectiveness of this vaccine, young women aged 18-22 will be asked to self-collect a sample for HPV detection which will determine if HPV types targeted by vaccine are reducing in prevalence.
Effectiveness And Cost-Effectiveness Of HPV Vaccination And HPV-Based Cervical Cancer Screening Strategies In China

Summary
In the absence of preventative initiatives, up to 187,000 women will develop cervical cancer in China every year. However, the disease is preventable using human papillomavirus (HPV) vaccination and primary HPV screening. Building on previous work, we will evaluate the most effective and cost-effective options for cervical cancer prevention, in order to provide an comprehensive evidence base for China’s health decision-makers.
