The use of online health techniques to assist with the delivery of specialist paediatric diabetes services in Queensland

We have tested an alternative method of delivering health services to regional areas of Queensland. By integrating telepaediatrics into an existing outreach programme for children with diabetes and endocrine conditions, we were able to reduce travel for specialist hospital staff while maintaining (and sometimes increasing) the contact patients had with the specialist team. In the first 28 months, we facilitated 160 patient consultations and 10 education sessions via videoconference through the telepaediatric service. By the end of the study, site visits were taking place annually and routine videoconference clinics were scheduled quarterly for the review of new patients and follow-up. Telepaediatric services in endocrinology and diabetes were established at three levels: the coordination of routine specialist clinics via videoconference; ad hoc patient consultations for collaborative management during acute presentations and at times of urgent clinical need; and the delivery of education to staff and patients throughout the state. The net result was improved access to specialist services from rural and remote areas of Queensland.

Young refugees talk about well-being: A qualitative analysis of refugee youth mental health from three states

Young people from refugee backgrounds face enormous challenges in the settlement process within Australia. They must locate themselves within a new social, cultural, geographic and adult space, yet also try to find security within the spaces of their own families and ethnic communities. Traumas of the past can mix with painful experiences of the present. The stressors in the lives of these young people can be both complex and diverse. This paper explores the nature a/these stressors among young people from refugee backgrounds living in Australia. [t is based On in-depth interviews with 76 young people from refugee backgrounds now living in Brisbane, Adelaide and Perth. A qualitative analysis of the impact of these stressors as well as the coping strategies employed are discussed It is argued that trauma exists

How young people from culturally and linguistically diverse backgrounds experience mental health: Some insights for mental health nurses

This article reports on part of a study that looked at the mental health of culturally and linguistically diverse (CALD) young people. The research sought to learn from CALD young people, carers, and service providers experiences relevant to the mental health of this group of young people. The ultimate goal was to gain insights that would inform government policy, service providers, ethnic communities and most importantly the young people themselves. To this end, qualitative interviews were undertaken with 123 CALD young people, 41 carers and 14 mental health service providers in Queensland, Western Australia and South Australia. Only one aspect of the study will be dealt with here, namely the views of the young CALD participants, which included risk factors, coping strategies and recommendations about how they could be supported in their struggle to maintain mental health. One of the most important findings of the study relates to the resilience of these young people and an insight into the strategies that they used to cope. The efforts of these young people to assist us in our attempts to understand their situation deserve to be rewarded by improvements in the care that we provide. To this end this article sets out to inform mental health nurses of the results of the study so that they will be in a position to better understand the needs and strengths of their CALD clients and be in a better position to work effectively with them.

Preliminary experience of allied health assessments delivered face to face and by videoconference to a residential facility for elderly people

We investigated whether allied health assessments carried out via videoconferencing were comparable to assessments carried out face to face. Five allied health therapists (in dietetics, occupational therapy, physiotherapy, podiatry and speech pathology) conducted an assessment of 12 high-dependency residents both face to face and by videoconferencing. On a five-point Likert scale, the therapists' mean ratings for the efficiency and suitability of videoconferencing for assessment were significantly lower than for face to face. Their mean rating for the adequacy of their care plans was also significantly lower for videoconferencing than for face to face. However, in each case the dietician's assessments did not differ significantly between the two modalities. In 35 cases out of 60, two independent raters agreed that the therapists' care plans after the videoconferencing and face-to-face assessments were the same. However, the level of agreement between raters was only moderate (kappa=0.31). Despite the therapists' (natural) preference for face-to-face working, care plans formulated via videoconferencing were reasonably similar to those formulated in face-to-face assessment. Allied health assessments carried out by videoconferencing would therefore seem to be feasible.

The cost of allied health assessments delivered by videoconference to a residential facility for elderly people

We calculated the cost of providing allied health assessments to high-dependency residents of a rural facility for elderly people. The costs of conducting assessments via videoconferencing were compared with the costs of conducting assessments face to face. The observed costs in a three-month pilot trial were used to estimate the annual costs. Given an annual workload of 1000 occasions of service, each videoconference assessment would cost $84.93, compared with $90.25 for face-to-face assessments. Allied health assessments delivered by videoconferencing became cheaper at workloads of approximately 850 occasions of service annually. Additional increases in the workload further improved the financial viability of this approach to service delivery.

Early patterns of sexual activity: age cohort differences in Australia

Patterns of first sexual activity among Australians born between the 1940s and 1980s were analysed using data from a national telephone survey of 1784 adults (876 males; 908 females). Sixty-one percent of those randomly selected from the Australian electoral roll and contactable by telephone responded. Many trends, including earlier first intercourse - from 20 to 18 years (females) and 18.8 to 17.8 years (males) - were established with the 40-49 year cohort, whose sexual debut was in the late 1960s-70s. Significant age-cohort effects saw women in the contemporary (18-29 year) cohort draw level with males for age at first intercourse and first sex before age 16 and before leaving school. First intercourse contraceptive use climbed from 30% to 80'%. Condom use quadrupled to 70%. Australian age-cohort effects are remarkably consistent with those in similar western cultures: gender convergence in sexual experience and increasing avoidance of sexually transmitted disease and pregnancy. If such trends continue, positive long-term outcomes for health and social wellbeing should result.

How does mental health status relate to accessibility and remoteness?

Objective: To determine whether mental illness is associated with accessibility and remoteness. Design: A cross-sectional, population-based, computer-assisted telephone interview survey, stratified by Accessibility and Remoteness Index of Australia (ARIA) categories. Setting: Secondary analysis of data collected from 2545 South Australian adults in October and November 2000. Outcome measures: Psychological distress and depression as determined by the Kessler 10 Psychological Distress Scale, the SF-12 measure of health status, and self-reported mental illness diagnosed by a doctor in the previous 12 months. Results: Overall, mental illness prevalence estimates were similar using the three measures of psychological distress (10.5%), clinical depression (12.9%) and self-reported mental health problem (12.7%). For each measure, there was no statistically significant variation in prevalence across ARIA categories, except for a lower than expected prevalence of depression (7.7%) in the accessible category. There was no trend suggesting higher levels of mental illness among residents of rural and remote regions. Conclusions: The prevalence rates of psychological distress, depression and self-reported mental illness are high. However, we found no evidence that the prevalence of these conditions varies substantially across ARIA categories in South Australia. This finding may challenge existing stereotypes about higher levels of mental illness outside metropolitan Australia.

Quality of life changes following peripheral blood stem cell transplantation and participation in a mixed-type, moderate-intensity, exercise program

The purpose of this investigation was to evaluate the impact of undertaking peripheral blood stem cell transplantation (PBST) on quality of life (QoL), and to determine the effect of participating in a mixed-type, moderate-intensity exercise program on QoL. It was also an objective to determine the relationship between peak aerobic capacity and QoL in PBST patients. QoL was assessed via the CARES questionnaire and peak aerobic capacity by a maximal graded treadmill test, pretransplant (PI), post transplant (PII) and following a 12-week intervention period (PIII). At PII, 12 patients were divided equally into a control or exercise intervention group. Undergoing a PBST was associated with a statistically but not clinically significant decline in QoL (P < 0.05). Following the intervention, exercising patients demonstrated an improved QoL when compared with pretransplant ratings (P < 0.01) and nonexercising transplant patients (P < 0.05). Moreover, peak aerobic capacity and QoL were correlated (P < 0.05). The findings demonstrated that exercise participation following oncology treatment is associated with a reduction in the number and severity of endorsed problems, which in turn leads to improvements in global, physical and psychosocial QoL. Furthermore, a relationship between fitness and QoL exists, with those experiencing higher levels of fitness also demonstrating higher QoL.

Expression of the cell surface mucin gene family in adenocarcinomas

Cell surface mucins are complex glycoproteins expressed on the apical membrane surface of mucosal epithelial cells. In malignant epithelial cells they are thought to influence cell adhesion, and are clinical targets for tumor immunotherapy and serum tumor marker assays. We have compared expression of MUC1, MUC3, MUC4, MUC11, MUC12 and MUC13 mRNA in epithelial cancers and/or cell lines with non-malignant tissues. In non-malignant tissues, MUC3, 4, 11, 12 and 13 were expressed at highest levels in gastrointestinal tissues, whereas MUC1 was more widely distributed. Significant down-regulation of the MUC4, MUC12 and MUC13 genes was observed in colonic cancers compared with normal tissue, whereas MUC1 was upregulated. In rectal cancers, levels of all six mucin genes were not significantly different to those in normal rectal tissues. Both MUC1 and MUC4 were down-regulated in gastric cancers, whereas cancer and normal tissue levels were similar for MUC3, 11, 12 and 13. In esophageal cancers there was a general trend toward higher levels than in normal tissue for MUC1, 3, 12 and 13. In ovarian cancers MUC1 levels were very high, whereas only low levels of all other mucins were observed. We also report expression in renal cell carcinomas, bladder carcinomas and breast cancer cell lines. The reported expression profiles of the cell surface mucin gene family will help direct biological and clinical studies of these molecules in mucosal biology, and in malignant and inflammatory diseases of epithelial tissues.

Acute cadmium chloride administration induces hepatic and renal CYP2A5 mRNA, protein and activity in the mouse: involvement of transcription factor NRF2

Modulation of the cytochrome P450 (CYP) monooxygenase system by cadmium was investigated in male, adult DBA/2J mice treated with a single dose (16 mumol/kg body weight, i.p.) of cadmium chloride (CdCl2). Total CYP content of liver and kidney microsomes decreased maximally (56% and 85%, respectively) 24 and 18 h, respectively, after CdCl2 treatment. Progressive increases of hepatic coumarin 7-hydroxylase (COH) activity; indicative of CYP2A5 activity, relative to the total CYP content were seen at 8 h (2-fold), 12 h (3-fold), 18 h (12-fold), and 24 h (15-fold). Similar changes were seen in the kidney. Liver and kidney CYP2A5 mRNA levels increased maximally 12 and 4 h after treatment and decreased to almost half 6 h later. In contrast, kidney and liver CYP2A5 protein levels increased maximally at 18 and 24 h. The CYP2A5 mRNA levels in the kidney and liver increased after Cd treatment in Nrf2 +/+ but not in Nrf2 -/- mouse. This study demonstrates that hepatic and kidney CYP2A5 is upregulated by cadmium with a somewhat faster response in the kidney than the liver. The strong upregulation of the CYP2A5 both at mRNA and enzyme activity levels, with a simultaneous decrease in the total CYP concentration suggest an unusual mode of regulation of CYP2A5 in response to cadmium exposure, amongst the CYP enzymes. The observed decrease in the mRNA but not in protein levels after maximal induction may suggest involvement of post-trancriptional mechanisms in the regulation. Upregulation of CYP2A5 by cadmium in the Nrf2 +/+ mice but not in the Nrf2 -/- mice indicates a role for this transcription factor in the regulation. (C) 2003 Elsevier Ireland Ltd.

Prevention of Cervical Cancer Through Papillomavirus Vaccination

A subset of human papillomaviruses (HPVs) promote anogenital malignancy, including cervical cancer, and prevention and treatment strategies that reflect the causal role of HPV are being developed. Vaccines based on HPV virus-like particles induce genotype-specific virus-neutralizing antibody and prevent infection with HPV1. Persistent papillomavirus infection is required for the development of papillomavirus-associated cancer and, therefore, therapeutic vaccines are being developed to eliminate established papillomavirus infection. Such vaccines test principles for the growing field of tumour-antigen-specific immunotherapy. This article reviews progress in the field and draws conclusions for the development of future prophylactic and therapeutic viral vaccines.

ISCOMATRIX (TM) adjuvant: An adjuvant suitable for use in anticancer vaccines

Human Papillomavirus type 16 (HPV16) E6 and E7 oncoproteins are associated with cervical cancer development and progression and can therefore be used as target antigens for cancer immunotherapy. In this study we evaluated the immunogenicity in mice, of different vaccine formulations using recombinant HPV16 derived E6E7 or E7GST fusion proteins. When co-administered with ISCOMATRIX(TM) adjuvant, these E6E7 proteins consistently induced E7 specific CTL, in vivo tumor protection, antibody and DTH responses. ISCOMATRIX(TM) adjuvant has been developed for use in the formulation of novel human vaccines and has been evaluated for safety and toxicity in human trials. A formulation containing aluminum hydroxide (Al(OH)(3)) gave a lesser degree of E7 specific antibody, and no local E7 specific CTL response but similar DTH and tumor protection. These findings demonstrate the potential of ISCOMATRIX(TM) adjuvant to stimulate both cellular and humoral immune responses to endogenously processed target antigens, and hence is the preferred adjuvant when CTL responses are desirable.

Prospective case review of a global e-health system for doctors in developing countries

The Swinfen Charitable Trust has managed email consultations for doctors in developing countries since 1999. The process was handled manually for the first three years and then subsequently using an automatic message-handling system. We conducted a prospective review of email consultations between referring doctors and consulting specialists during six months of automatic operation (December 2003 to May 2004). During the study period 125 consultations took place. These concerned a wide range of specialties (e.g. orthopaedics 17%, dermatology 16%, obstetrics and gynaecology 11%, radiology 10%). Of these referrals, 33% (41) were for paediatric cases. Consulting specialists, who were based in five countries, were volunteers. Referring doctors were from 24 hospitals in 12 developing countries. The median time from referral to definitive reply was 1.5 days (interquartile range 0.6-4.9). There was an 85% response rate (n = 106) to a survey concerning the value of the consultation to the referring doctor. All the referring doctors who responded made positive comments about the service and half said that it improved their management of the case. The second-opinion consultation system operated by the Swinfen Charitable Trust represents an example of a global e-health system operated for altruistic, rather than commercial, reasons.
