Secondary arm lymphoedema is a chronic and distressing condition which affects a significant number of women who undergo breast cancer treatment. A number of health professional and patient instigated conservative therapies have been developed to help with this condition, but their comparative benefits are not clearly known. This systematic review undertook a broad investigation of commonly instigated conservative therapies for secondary arm lymphoedema including; complex physical therapy, manual lymphatic drainage, pneumatic pumps, oral pharmaceuticals, low level laser therapy, compression bandaging and garments, limb exercises and limb elevation. It was found that the more intensive and health professional based therapies, such as complex physical therapy, manual lymphatic drainage, pneumatic pump and laser therapy generally yielded the greater volume reductions, whilst self instigated therapies such as compression garment wear, exercises and limb elevation yielded smaller reductions. All conservative therapies produced improvements in subjective arm symptoms and quality of life issues, where these were measured. Despite the identified benefits, there is still the need for large scale, high level clinical trials in this area.

We investigated the feasibility of providing telerehabilitation in the home as an alternative to conventional ambulatory rehabilitation. Two groups of patients were accepted for telerehabilitation. The first group were community patients who needed rehabilitation, e.g. following a stroke, a fracture or prolonged hospital admission. The second group was from two rural nursing homes where residents were identified with a recent injury, fall or hospitalisation. Telerehabilitation employed a coaching model, with fewer therapist home visits, more feedback and "homework" for the patient. Patients had a tablet computer loaded with a videoconferencing app to connect with therapists and relevant therapeutic apps. Multidisciplinary care was provided for up to 8 weeks. The majority (86%) of eligible patients consented to receive telerehabilitation in their own home (n = 61) or in the country nursing home where they lived (n = 17). Most services were delivered using the 3G and 4G wireless networks with few technical problems. On average participants felt that they had achieved 75% of the goals set at the beginning of the programme. High levels of satisfaction were recorded. There was a 50% reduction in home visits by staff, or 10 visits per patient. Speech therapists were able to double occasions of service and direct patient contact time, whilst halving their travel time. Previous experience with technology and age were not barriers to this method of delivery but did affect recruitment. Telerehabilitation using off-the-shelf technology is feasible for post-acute treatment.

The ability of the lymphatic system to actively remove fluid from the interstitium is critical to the resolution of edema. The response of the lymphatics to inflammatory situations is poorly studied, so we examined mesenteric lymphatic contractile activity in the 2,4,6-trinitrobenzenesulfonic acid (TNBS) model of guinea pig ileitis, a well-accepted animal model of intestinal inflammation, by videomicroscopy in vivo and in vitro 1, 3, and 6 days after induction of ileitis. Lymphatic function (diameter, constriction frequency, amplitude of constrictions, and calculated stroke volume and lymph flow rate) of isolated vessels from TNBS-treated guinea pigs were impaired compared with sham-treated controls. The dysfunction was well correlated with the degree of inflammation, with differences reaching significance (P < 0.05) at the highest inflammation-induced damage observed at day 3. In vivo, significantly fewer lymphatics exhibited spontaneous constrictions in TNBS-treated than sham-treated animals. Cyclooxygenase (COX) metabolites were suggested to be involved in this lymphatic dysfunction, since application of nonselective COX inhibitor (10 microM indomethacin) or a combination of COX-1 and COX-2 inhibitors (1 microM SC-560 and 10 microM celecoxib) markedly increased constriction frequency or induced them in lymphatics from TNBS-treated animals in vivo and in vitro. The present results demonstrate that lymphatic contractile function is altered in TNBS-induced ileitis and suggest a role for prostanoids in the lymphatic dysfunction.

Although the role of the islets in the regulation of acinar cell function seemed a mystery to investigators who observed their dispersion among pancreatic acini, over time an appreciation for this intricate and unique structural arrangement has developed. The last three decades have witnessed a steadily growing understanding of the interrelationship of the endocrine and the exocrine pancreas. The islet innervation and vascular anatomy have been more fully characterized and provide an appropriate background for our current understanding. The interrelationship between the endocrine and exocrine pancreas is mediated by islet-derived hormones such as insulin and somatostatin, other humoral factors including pancreastatin and ghrelin, and also neurotransmitters (nitric oxide, peptide YY, substance P, and galanin) released by the nerves innervating the pancreas. Although considerable progress has been achieved, further work is required to fully delineate the complex interplay of the numerous mechanisms involved. This review aims to provide a comprehensive update of the current literature available, bringing together data gleaned from studies addressing the actions of individual hormones, humoral factors, and neurotransmitters on the regulation of amylase secretion from the acinar cell. This comprehensive view of the islet-acinar axis of the pancreas while acknowledging the dominant role played by insulin and somatostatin on exocrine secretion sheds light on the influence of the various neuropeptides on amylase secretion.

Information and communications technology has become central to the way in which health services are provided. Technology-enabled services in healthcare are often described as eHealth, or more recently, digital health. Practitioners may require new knowledge, skills and competencies to make best use of eHealth, and while universities may be a logical place to provide such education and training, a study in 2012 found that the workforce was not being adequately educated to achieve competence to work with eHealth. We revisited eHealth education and training in Australian universities with a focus on medical schools; we aimed to explore the progress of eHealth in the Australian medical curriculum. We conducted a national interview study and interpretative phenomenological analysis with participants from all 19 medical schools in Australia; two themes emerged: (i) consensus on the importance of eHealth to current and future clinical practice; (ii) there are other priorities, and no strong drivers for change. Systemic problems inhibit the inclusion of eHealth in medical education: the curriculum is described as ‘crowded’ and with competing demands, and because accrediting bodies do not expect eHealth competence in medical graduates, there is no external pressure for its inclusion. Unless and until accrediting bodies recognise and expect competence in eHealth, it is unlikely that it will enter the curriculum; consequently the future workforce will remain unprepared.

BackgroundThis study was a component of the Flinders Telehealth in the Home project, which tested adding home telehealth to existing rehabilitation, palliative care and geriatric outreach services. Due to the known difficulty of transitioning telehealth projects services, a qualitative study was conducted to produce a preferred implementation approach for sustainable and large-scale operations, and a process model that offers practical advice for achieving this goal.MethodsInitially, semi-structured interviews were conducted with senior clinicians, health service managers and policy makers, and a thematic analysis of the interview transcripts was undertaken to identify the range of options for ongoing operations, plus the factors affecting sustainability. Subsequently, the interviewees and other decision makers attended a deliberative forum in which participants were asked to select a preferred model for future implementation. Finally, all data from the study was synthesised by the researchers to produce a process model.Results19 interviews with senior clinicians, managers, and service development staff were conducted, finding strong support for home telehealth but a wide diversity of views on governance, models of clinical care, technical infrastructure operations, and data management. The deliberative forum worked through these options and recommended a collaborative consortium approach for large-scale implementation. The process model proposes that the key factor for large-scale implementation is leadership support, which is enabled by 1) showing solutions to the problems of service demand, budgetary pressure and the relationship between hospital and primary care, 2) demonstrating how home telehealth aligns with health service policies, and 3) achieving clinician acceptance through providing evidence of benefit and developing new models of clinical care. Two key actions to enable change were marketing telehealth to patients, clinicians and policy-makers, and building a community of practice.ConclusionsThe implementation of home telehealth services is still in an early stage. Change agents and a community of practice can contribute by marketing telehealth, demonstrating policy alignment and providing potential solutions for difficult health services problems. This should assist health leaders to move from trials to large-scale services.
