Exploring clinical learning experiences of novice physiotherapy students in a hospital setting.

BACKGROUND: Exposure to clinical practice experiences ensures undergraduate physiotherapy students meet the clinical competencies required to graduate as autonomous practitioners. Much of the research literature has investigated the clinical experiences of medical students. While recent studies have explored physiotherapy students' experiences with simulation, few have explored their perspectives of a clinical placement in a hospital setting at the early learning stage of a four-year programme. OBJECTIVE: To explore the perspectives of novice undergraduate physiotherapy students on a clinical placement in a real hospital setting. METHODS: Fifteen Year 3 undergraduate physiotherapy students participated in semi-structured interviews midway through a three-week tertiary care clinical placement. Interviews were transcribed, coded and analyzed using thematic analysis. RESULTS: Three main themes emerged: 1) student attributes affecting placement experience; 2) impact of the educator on student experience; and 3) effects of the clinical environment on student experiences. CONCLUSION: The real clinical environment promotes a rich learning experience for students, while the clinical educator is pivotal to guiding student learning through provision of resources and feedback. Provision of early orientation and timely clarification of expectations is important to alleviate anxiety and allow students to prepare themselves.

International collaboration to improve physiotherapists' training, Viet Nam.

Problem: Like most low- and middle-income countries, Viet Nam has a scarcity of rehabilitation professionals and lacks training programmes that meet international standards. Approach: In 2018, four Vietnamese medical universities, the Université Catholique de Louvain, the Université Libre de Bruxelles, the Humanity & Inclusion charity and World Physiotherapy agreed to collaborate on strengthening pre-service education for physiotherapists in the country. Local setting: Viet Nam has a favourable environment for nurturing rehabilitation services and education: development funds have been available; government investment is increasing; and rehabilitation education has existed for many decades. Relevant changes: The collaboration resulted in the establishment of: (i) a 4-year, competency-based, entry-level curriculum for physiotherapists (bachelor's degree); (ii) opportunities for continuing professional development; (iii) a 2-year master's programme for physiotherapy lecturers and clinical supervisors; and (iv) a national physiotherapy association. In addition, four students were supported in studying for PhD degrees. Strong collaboration and comprehensive and complementary interventions have laid the foundations for sustainable, high-quality, educational programmes for physiotherapists, which will improve access to, and the standard of, rehabilitation services in Viet Nam, thereby leading to better patient outcomes. Lessons learnt: Curricula for entry-level physiotherapy programmes should be competency-based, be actively managed by national educators and meet international standards while being responsive to local priorities. To strengthen the rehabilitation workforce, educators involved in teaching and supervising training programmes should have the skills and knowledge required. A national professional physiotherapy association should be established to provide continuing professional development for physiotherapists and to take part in international collaborations.

Proposal for a National Interprofessional School of Rural Health.

Shortages of health professionals persist in much of rural New Zealand despite a range of targeted university and professional college initiatives. In response to this a collective of universities, professional colleges and sector groups have put a proposal to Government for a National Interprofessional School of Rural Health. If adopted, this proposal would embed rural health professional education and research in rural communities around New Zealand, empowering them to organise the education that occurs in their community, in a coherent and coordinated way. What is being proposed is not a new or separate education provider but rather an 'enabling body' that would lever off the expertise and resources of the existing tertiary institutions, colleges and rural communities. It calls for an 'all of systems' approach that encompasses all the health professions that practise in rural areas, undergraduate education and postgraduate training, and rural health research. Although modelled on successful Australian rural clinical schools, it is a uniquely New Zealand solution that is cognisant of the New Zealand context and resources.

Acupuncture for chronic low back pain: a randomized controlled feasibility trial comparing treatment session numbers.

OBJECTIVE: To evaluate the feasibility of a randomized controlled trial investigating the optimal number of treatment sessions of acupuncture, used as an adjunct to usual care, for managing chronic low back pain. METHODS: In total, 45 participants with chronic low back pain were recruited and randomly allocated to receive usual care plus 4, 7, or 10 sessions of acupuncture (15/group). Primary outcomes were recruitment rate, randomization rate, treatment compliance, completion of the outcome measures, and retention rates. Secondary outcomes included back function, pain intensity and bothersomeness, generic health status, activity disability, and participant satisfaction. Data were collected at baseline and discharge, and at 6 and 12 weeks post randomization. RESULTS: The recruitment method was demonstrated to be successful: recruitment rate was 43.7%, and randomization rate was 100%. Compliance with treatment was high among participants (86.7%, 86.7%, and 100% for the 4-, 7-, and 10-session group, respectively). Outcome questionnaires used in this study were found to be appropriate for a future randomized controlled trial. Participant retention rates were 88.9% at discharge and at 6 weeks post randomization and 84.4% at 12 weeks post randomization. Secondary outcomes (except for pain intensity) favored the 10-session acupuncture group at 12 weeks post randomization. Over 90% of participants indicated that they were "very satisfied" and/or "extremely satisfied" with the acupuncture treatment. CONCLUSION: This study demonstrated that a full-scale randomized controlled trial using the methodology described above is feasible, and such a trial is essential to test the dose dependence of acupuncture.

Consumption of antimicrobial manuka honey does not significantly perturb the microbiota in the hind gut of mice.

The aim of this study was to test the hypothesis that consuming manuka honey, which contains antimicrobial methylglyoxal, may affect the gut microbiota. We undertook a mouse feeding study to investigate whether dietary manuka honey supplementation altered microbial numbers and their production of organic acid products from carbohydrate fermentation, which are markers of gut microbiota function. The caecum of C57BL/6 mice fed a diet supplemented with antimicrobial UMF® 20+ manuka honey at 2.2 g/kg animal did not show any significantly changed concentrations of microbial short chain fatty acids as measured by gas chromatography, except for increased formate and lowered succinate organic acid concentrations, compared to mice fed a control diet. There was no change in succinate-producing Bacteroidetes numbers, or honey-utilising Bifidobacteria, nor any other microbes measured by real time quantitative PCR. These results suggest that, despite the antimicrobial activity of the original honey, consumption of manuka honey only mildly affects substrate metabolism by the gut microbiota.

Traditional Chinese Medicine acupuncture and myofascial trigger needling: The same stimulation points?

BACKGROUND: Acupuncture originates in China, and its effectiveness has been well documented in musculoskeletal pain disorders and other conditions. A widely accepted contemporary medical treatment option for myofascial pain is trigger point needling. Although there are many differences between Traditional Chinese Medicine acupuncture theory and the myofascial trigger point needling framework, it is argued that the stimulation sites for these two needling modalities are similar. DISCUSSION: In this paper we examined the correspondence between Traditional Chinese Medicine acupoints and myofascial trigger points. Based on this correspondence, we considered exploration of Ah-shi points from four aspects: pain recognition, distal Ah-shi points, Anti-Ah-shi points, and management approaches. SUMMARY: The extent of correspondence is influenced by definitions of acupoints. Myofascial trigger points are significantly correlated to Traditional Chinese Medicine acupoints, including primary channel acupoints, extra acupoints, and Ah-shi points. Considering the correlation between MTrPs and acupoints and the rarely-studied research area of Ah-shi points, it may be reasonable to incorporate research findings of myofascial trigger points into further investigations into Ah-shi points. Correspondence between myofascial trigger points and acupoints enhances contemporary understanding of the mechanism of action of acupuncture, and may serve to facilitate increased integration of acupuncture into clinical management.

Interprofessional education in a rural community: the perspectives of the clinical workplace providers.

INTRODUCTION Interprofessional education is internationally recognised as a key element in preparing a collaborative practice-ready health workforce, for improving health care outcomes and patient-centred practice. The Tairawhiti interprofessional education (TIPE) programme was introduced in 2012 in a rural area with a high Maori population. Students from seven health professions: dentistry, dietetics, medicine, nursing, occupational therapy, pharmacy and physiotherapy participated in clinical rotations as well as working in Maori communities with Maori health providers. AIM The primary aim was to retrospectively investigate clinical workplace providers' perspectives on their participation in the TIPE project over its first 3 years. METHODS Face-to-face, semi-structured interviews were completed with 16 clinical workplace providers involved in TIPE. A qualitative approach using template analysis methodology and a priori themes was used to identify predominant themes from the providers' perspectives. RESULTS All 16 providers reported positive experiences during their involvement in TIPE and wished to continue with this educational model. Benefits described included greater interprofessional collaboration at the workplace; improved engagement between students and providers; enhanced patient-centred care, particularly with Maori and whanau; and positive outcomes from community projects undertaken by the students. Although providers acknowledged additional costs on time, pressure on staff and extra workloads, all confirmed that the benefits from the project far outweighed the costs. CONCLUSION From the providers' perspectives, the TIPE project met its objectives. Furthermore, providers noted several students had re-located back to Tairawhiti to work as health professionals, which suggests that investment in TIPE adds long-term value to the community.

No difference in fecal levels of bacteria or short chain fatty acids in humans, when consuming fruit juice beverages containing fruit fiber, fruit polyphenols, and their combination.

This study examined the effect of a Boysenberry beverage (750 mg polyphenols), an apple fiber beverage (7.5 g dietary fiber), and a Boysenberry plus apple fiber beverage (750 mg polyphenols plus 7.5 g dietary fiber) on gut health. Twenty-five individuals completed the study. The study was a placebo-controlled crossover study, where every individual consumed 1 of the 4 treatments in turn. Each treatment phase was 4-week long and was followed by a 2-week washout period. The trial beverages were 350 g taken in 2 doses every day (ie, 175 mL taken twice daily). The hypothesis for the study was that the combination of polyphenols and fiber would have a greater benefit on gut health than the placebo product or the fiber or polyphenols on their own. There were no differences in fecal levels of total bacteria, Bacteroides-Prevotella-Porphyromonas group, Bifidobacteriumspecies, Clostridium perfringens, or Lactobacillus species among any of the treatment groups. Fecal short chain fatty acid concentrations did not vary among treatment groups, although prostaglandin E2 concentrations were higher after consumption of the Boysenberry juice beverage. No significant differences were found in quantitative measures of gut health between the Boysenberry juice beverage, the apple fiber beverage, the Boysenberry juice plus apple fiber beverage, and the placebo beverage.

Effects of kiwifruit on innate and adaptive immunity and symptoms of upper respiratory tract infections.

Maintenance of an adequate and properly regulated immune system is essential for health and well-being. Components in food may modulate immune responses in a positive way (immunonutrition), and some of these components are present in kiwifruit. Kiwifruit contains vitamin C, carotenoids, polyphenols, and dietary fiber, and these are all potentially beneficial to the immune system. Research that has contributed to our understanding of the beneficial effects that kiwifruit may have on immune responses spans from in vitro studies using cell lines and human blood cells, to using animal models targeting both mucosal and systemic immunity. Some limited human intervention trials have been undertaken and are described, in which kiwifruit has been shown to influence a number of biomarkers of oxidative stress and beneficial immune responses, to reduce the incidence and severity of symptoms of upper respiratory tract infections and potentially be more beneficial than supplementation with vitamin C alone.

Lessons to be learned: a retrospective analysis of physiotherapy injury claims.

STUDY DESIGN: Retrospective, descriptive analysis. OBJECTIVES: To describe the prevalence and nature of insurance claims for injuries attributed to physiotherapy care. BACKGROUND: In New Zealand, a national insurance scheme, the Accident Compensation Corporation, provides comprehensive, no-fault personal injury coverage. The patterns of injury sustained during physiotherapy care have not previously been described. METHODS: De-identified data for all injuries registered with the Accident Compensation Corporation from 2005 to 2010 and attributed to physiotherapy were accessed. Prevalence patterns (percentages) of new-claim data were determined for physiotherapy intervention category, injury site, nature of injury, age, and sex. A subcategory, exercise-related injuries, was analyzed according to injury site and whether the injury was related (primary) or unrelated (secondary) to the intended therapeutic goal. RESULTS: There were 279 claims related to physiotherapy care filed with the Accident Compensation Corporation during the studied reporting period. Injury was attributed predominantly to exercise (n = 88, 31.5% of cases) and manual therapy (n = 74, 26.5% of cases). The prevalence of events categorized as exercise related was greatest in those who were 55 to 59 years of age (n = 14, 16.3%) and greater in females (n = 47, 54.7%). Of the exercise-related injuries, 39.8% were in the lower-limb region and 35.2% were categorized as sprains/strains. CONCLUSION: Injuries attributed to exercise exceeded those linked to other therapies provided by physiotherapists, yet exercise therapy rarely features as a cause of adverse events reported to the physiotherapy profession. The proportion of exercise-related injury events underlines the need for ensuring safe and careful consideration of exercise prescription. LEVEL OF EVIDENCE: Harm, level 4.

Arabinogalactan proteins contribute to the immunostimulatory properties of New Zealand honeys.

CONTEXT: Factors in honey that improve wound healing are poorly understood, but are thought to include lipopolysaccharide (LPS), apalbumin-1 and -2, and a 5.8 kDa component that stimulate cytokine release from macrophages. OBJECTIVE: To characterize the ability of New Zealand honeys to elicit the release of tumor necrosis factor-α (TNF-α) from monocytic cell lines as a model for early events within a wound site. MATERIALS AND METHODS: The ability of kanuka (Kunzea ericoides), manuka (Leptospermum scoparium), and clover (Trifolium spp.) honeys to stimulate the release of TNF-α from monocytic cell lines THP-1 and U937 was assayed by ELISA. RESULTS: All three honeys stimulated TNF-α release from THP-1 cells, with kanuka honey being the most active. The activity of kanuka honey was associated with a high molecular weight (>30 kDa) component that was partially heat labile and inhibitable with polymyxin B. LPS concentrations in the honeys were too low to adequately explain the level of immunostimulation. The contribution of type II arabinogalactan proteins (AGPs) we recently identified in kanuka honey was tested, as AGPs are known immunostimulators. AGPs purified from kanuka honey stimulated the release of TNF-α from THP-1 and U937 cells. DISCUSSION: Here we demonstrated that AGPs we recently identified in kanuka honey have immunostimulatory activity. We propose that the immunostimulatory properties of individual honeys relate to their particular content of LPS, apalbumins, the 5.8 kDa component and AGPs. CONCLUSION: The immunostimulatory activity of kanuka honey may be particularly dependent on AGPs derived from the nectar of kanuka flowers.

Consumption of gold kiwifruit reduces severity and duration of selected upper respiratory tract infection symptoms and increases plasma vitamin C concentration in healthy older adults.

In the elderly, immunosenescence and malnourishment can contribute to increased risk and severity of upper respiratory tract infections (URTI). Gold kiwifruit (Actinidia chinensis 'Hort16A') contains nutrients important for immune function and mitigation of symptoms of infection, including vitamins C and E, folate, polyphenols and carotenoids. The objective of the present study was to evaluate whether regular consumption of gold kiwifruit reduces symptoms of URTI in older people, and determine the effect it has on plasma antioxidants, and markers of oxidative stress, inflammation and immune function. A total of thirty-two community-dwelling people (≥65 years) participated in a randomised crossover study, consuming the equivalent of four kiwifruit or two bananas daily for 4 weeks, with treatments separated by a 4-week washout period. Participants completed the Wisconsin Upper Respiratory Symptom Survey-21 daily, and blood samples were collected at baseline and at the end of each treatment and washout period. Gold kiwifruit did not significantly reduce the overall incidence of URTI compared with banana, but significantly reduced the severity and duration of head congestion, and the duration of sore throat. Gold kiwifruit significantly increased plasma vitamin C, α-tocopherol and lutein/zeaxanthin concentrations, and erythrocyte folate concentrations, and significantly reduced plasma lipid peroxidation. No changes to innate immune function (natural killer cell activity, phagocytosis) or inflammation markers (high-sensitivity C-reactive protein, homocysteine) were detected. Consumption of gold kiwifruit enhanced the concentrations of several dietary plasma analytes, which may contribute to reduced duration and severity of selected URTI symptoms, offering a novel tool for reducing the burden of URTI in older individuals.

Changes in markers of inflammation, antioxidant capacity and oxidative stress in smokers following consumption of milk, and milk supplemented with fruit and vegetable extracts and vitamin C.

Two milk-based beverages delivering twice the average daily antioxidant intake were formulated, based on synergistic combinations of fruit and vegetable extracts, and containing vitamin C (1.00 mg/ml) for shelf stability. Smokers (n = 42) consumed prototype milk A, B or non-supplemented milk (no extracts or vitamin C; 200 ml) twice daily for 6 weeks. Fasting and post-prandial (2 h after milk consumption) blood samples were collected at baseline and the end of each treatment. Non-supplemented milk significantly reduced fasting inflammatory cytokines (interleukin (IL) 6, IL-1ß, tumour necrosis factor-α) compared to baseline. Both supplemented milk-based beverages significantly increased fasting plasma vitamin C concentrations and antioxidant potential and decreased serum uric acid, compared to non-supplemented milk. The beverages did not induce post-prandial oxidative stress or inflammation. Therefore, regular consumption of the supplemented milks may confer health benefits because of increased antioxidant potential or through mechanisms resulting from increased vitamin C or decreased uric acid concentrations.

Antioxidant and 'natural protective' properties of kiwifruit.

Kiwifruit are nutrient-dense fruit with a reputation for promoting good health. Although this could be attributed to the high vitamin C content of kiwifruit, other phytochemicals could also provide health benefits. Kiwifruit are commonly reported to be a good source of vitamin E and in addition contain phenolics and carotenoids. The antioxidant properties of kiwifruit have received attention as possible mechanisms for their health-promoting effects. In this review, the antioxidant capacity of kiwifruit is discussed in the context of biologically relevant in vitro assays for predicting antioxidant activity in a biological setting compared with chemical antioxidant assays, and the ability of kiwifruit to protect cells from dying after exposure to an oxidative insult by hydrogen peroxide (cytoprotection). Some recent data are included, where extracts from twenty kiwifruit genotypes, derived from germplasm held at The New Zealand Institute for Plant & Food Research Ltd, were compared for their cellular antioxidant activity and cytoprotection, using human gut-derived epithelial cell lines. Our knowledge of how this type of result is currently reflected in vivo is summarised, together with the 'naturally protective' properties of kiwifruit that involve modulating immune responses in a positive way. Finally, the ways in which these antioxidant and natural protective properties of kiwifruit may influence human health and wellness are discussed.

Gold kiwifruit ( Actinidia chinensis 'Hort16A') for immune support.

Kiwifruit is a good source of several vitamins and minerals and dietary fibre, and contains a number of phytochemicals; so kiwifruit potentially provides health benefits beyond basic nutrition. Consumption of green kiwifruit can have positive effects on cardiovascular health through antioxidant activity, inhibition of platelet aggregation and lowered TAG levels, and gut health through improving laxation, aiding digestion and promoting a healthy gut microflora. The importance of nutrition on immune function is well recognised, with deficiencies in vitamins A, C, E, B6 and B12, folic acid, Zn, Cu, Fe and Se being associated with impaired immune function and increased susceptibility to diseases. Evidence is growing that kiwifruit enhances immunity, with several small murine studies showing enhancement of innate and adaptive immune function. Few studies have examined the effect of kiwifruit on immune function in human subjects, but a recent study has revealed that kiwifruit up-regulates several 'immune' and 'DNA and repair'-related gene sets, and down-regulates one gene set related to Ig secretion. Taken together, the evidence from the literature provides supporting data for designing a human intervention trial to validate the ability of kiwifruit to support immune function in healthy and immunocompromised populations.

Changes in head and neck posture using an office chair with and without lumbar roll support.

STUDY DESIGN: A repeated measures observational study. OBJECTIVE: To investigate change in sagittal alignment of head and neck posture in response to adjustments of an office chair with and without a lumbar roll in situ. SUMMARY OF BACKGROUND DATA: Forward head posture has been identified as a risk factor for neck pain, and there is evidence to show that ergonomic correction in sitting may reduce the incidence of pain. The effect placement of a lumbar roll has on cervical spine posture has not been previously investigated experimentally but rather, is assumed to have a positive influence on head and neck posture. METHODS: Thirty healthy male participants (18-30 years) were photographed while registered in the natural head resting position in each of 4 sitting positions with and without a lumbar roll in situ. Two positions incorporated adjustments to the back rest and 1 to the seat pan of the office chair. The craniovertebral (CV) angle, as a determinant of head and neck posture was measured from the set of digitized photographs obtained for each participant. Comparisons between the CV angle in all postural registrations were made using a mixed model analysis adjusted for multiple comparisons. RESULTS: Of the positions examined, significant differences in the mean CV angles were found with the backrest of the chair at 100 degrees and at 110 degrees (P < 0.001). With the lumbar roll in situ and the backrest position at 110 degrees , there was a significant increase in the mean CV compared with the angle without the lumbar roll in situ (2.32 degrees , 95% confidence interval: 1.31-3.33; P < 0.001). CONCLUSION: The degree of angulation of the backrest support of an office chair plus the addition of lumbar roll support are the 2 most important factors to be taken into account when considering seating factors likely to favorably change head and neck postural alignment, at least in asymptomatic subjects.

Kiwifruit-based polyphenols and related antioxidants for functional foods: kiwifruit extract-enhanced gluten-free bread.

The present study investigates the production of gluten-free bread enhanced with polyphenols and related antioxidants derived from a natural aqueous extract from green-fleshed kiwifruit (Actinidia deliciosa). Puree and four aqueous extracts, produced from ripe green kiwifruit in the absence of artificial preservatives, were subjected to storage stability trials at 4 degrees C, 20 degrees C and 38 degrees C, and were chemically characterized (phenolic, vitamin C and pectic polysaccharide contents). The aqueous extract with good stability and high phenolic and vitamin C contents was used for gluten-free bread-making. The resultant kiwifruit extract-enhanced bread was acceptable to a taste panel, possessing softer and smoother texture than plain gluten-free bread. Thus, the aqueous extract of kiwifruit puree containing health-beneficial constituents can be considered a functional ingredient for gluten-free bread formulation.

Chemical composition and in vitro anti-inflammatory activity of apple phenolic extracts and of their sub-fractions.

Apple extract powders from three different manufacturers were investigated for their anti-inflammatory activity, their total phenolic content, and their chemical composition. The samples represented two production batches for two products and a single batch of a third. The samples showed similar, but clearly different, anti-inflammatory activities, and had substantially different total phenolic contents, and different chemical compositions. Differences in chemical composition for batches of the same product were significant, although not as great as differences between products. The samples were fractionated into chemical classes. The most active fractions were those that contained epicatechin, catechin with phloridzin and quercetin glycosides, or those that contained procyanidin polymers. It was not possible to link activity to the presence of individual components or combinations of these. If fruit extracts are to be reliably linked to validated health benefits, then the source materials, the extraction processes, and the final composition of such products need to be more clearly defined than at present.

Feeding ZESPRI GOLD Kiwifruit puree to mice enhances serum immunoglobulins specific for ovalbumin and stimulates ovalbumin-specific mesenteric lymph node cell proliferation in response to orally administered ovalbumin.

The health benefits of fruits have been recognized for some time, but only recently have their effects on the immune system been investigated. Kiwifruit contains vitamins, minerals, and phytochemicals that are known to be important for normal functioning of the immune system. In this work, the influence of feeding 2 ZESPRI GOLD Kiwifruit processed products (Tauranga, New Zealand) on immune function in mice was investigated. Using a model to demonstrate adaptive immune responses in the gut, mice were fed either ZESPRI GOLD Kiwifruit puree or ZESPRI GOLD Kiwifruit 40 degrees Brix Juice concentrate for 20 days, during which time they were immunized via the oral route with ovalbumin and subsequently given a suboptimal dose of the mucosal adjuvant cholera toxin. ZESPRI GOLD Kiwifruit puree enhanced the response to ovalbumin by significantly increasing the levels of total immunoglobulins and immunoglobulin G specific for ovalbumin and enhanced the antigen-specific proliferation of cells from the draining mesenteric lymph nodes compared with mice fed a 20% sugar control. These results indicate that ZESPRI GOLD Kiwifruit can modulate an antigen-specific immune response and suggest that ZESPRI GOLD Kiwifruit may represent a new type of functional food ingredient.

Efficacy of the 'tennis ball technique' versus nCPAP in the management of position-dependent obstructive sleep apnoea syndrome.

BACKGROUND AND OBJECTIVE: Avoidance of sleep in the supine position is recommended in the management of position-dependent OSA hypopnoea syndrome (OSAHS). Our aim was to evaluate the efficacy of a thoracic anti-supine band (TASB), designed to mimic the so-called 'tennis ball technique', compared with nasal CPAP (nCPAP). METHODS: Twenty adults with mild to moderately severe position-dependent OSAHS (mean AHI +/- SD) 22.7 +/- 12.0/H (range 6.0-51.2); AHI supine, 59.6 +/- 27.5/H, were included in a randomized cross-over trial. Portable sleep studies were undertaken at baseline and after 1 month on each treatment. A successful treatment outcome was defined as AHI
