An evaluation of seasonal variations in footwear worn by adults with inflammatory arthritis: a cross-sectional observational study using a web-based survey

Background: Foot problems are common in adults with inflammatory arthritis and therapeutic footwear can be effective in managing arthritic foot problems. Accessing appropriate footwear has been identified as a major barrier, resulting in poor adherence to treatment plans involving footwear. Indeed, previous New Zealand based studies found that many people with rheumatoid arthritis and gout wore inappropriate footwear. However, these studies were conducted in a single teaching hospital during the New Zealand summer therefore the findings may not be representative of footwear styles worn elsewhere in New Zealand, or reflect the potential influence of seasonal climate changes. The aim of the study was to evaluate seasonal variations in footwear habits of people with inflammatory arthritic conditions in New Zealand. Methods: A cross-sectional study design using a web-based survey. The survey questions were designed to elicit demographic and clinical information, features of importance when choosing footwear and seasonal footwear habits, including questions related to the provision of therapeutic footwear/orthoses and footwear experiences. Results: One-hundred and ninety-seven participants responded who were predominantly women of European descent, aged between 46–65 years old, from the North Island of New Zealand. The majority of participants identified with having either rheumatoid arthritis (35%) and/or osteoarthritis (57%) and 68% reported established disease (>5 years duration). 18% of participants had been issued with therapeutic footwear. Walking and athletic shoes were the most frequently reported footwear type worn regardless of the time of year. In the summer, 42% reported wearing sandals most often. Comfort, fit and support were reported most frequently as the footwear features of greatest importance. Many participants reported difficulties with footwear (63%), getting hot feet in the summer (63%) and the need for a sandal which could accommodate a supportive insole (73%). Conclusions: Athletic and walking shoes were the most popular style of footwear reported regardless of seasonal variation. During the summer season people with inflammatory arthritis may wear sandals more frequently in order to accommodate disease-related foot deformity. Healthcare professionals and researchers should consider seasonal variation when recommending appropriate footwear, or conducting footwear studies in people with inflammatory arthritis, to reduce non-adherence to prescribed footwear

Fear of falling and foot pain, impairment and disability in rheumatoid arthritis: a case-control study

Fear of falling, foot pain, impairment and disability are commonly reported in rheumatoid arthritis (RA). However, the relationship between fear of falling and foot pain, impairment and disability has not been investigated in established RA. The aim of the study was to evaluate the relationship between fear of falling and foot pain, walking velocity and foot impairment and disability in women with established RA. A secondary aim was to evaluate differences between fear of falling, foot pain, walking velocity and foot impairment and disability in women with established RA and age- and sex-matched control participants. Twenty-one women with established RA and twenty-one age- and sex-matched controls were assessed for fear of falling, foot pain, foot impairment and disability and walking velocity. Pearson’s r-correlations were used to examine relationships between fear of falling and the foot measures. Independent samples t tests evaluated the differences in fear of falling and foot measures between the two groups. In people with RA, significant correlations were found between fear of falling and foot impairment (r = 0.53, p = 0.015), foot disability (r = 0.77, p <0.001) and walking velocity (r = 0.56, p < 0.001). No correlation was found between fear of falling and foot pain (r = 0.36; p = 0.11). Significant differences between cases and control participants were found between fear of falling (p = 0.001), foot impairment (p = 0.004) and foot disability (p < 0.001). Foot impairment and disability relates to fear of falling in women with established RA. A better understanding of fear of falling in people with established RA may contribute to more efficient falls assessments in order to identify at risk individuals

Development of a collaborative training partnership in the NZ construction industry

In 2015 a first tier New Zealand commercial construction company approached the Department of Construction at Unitec regarding the company’s professional development training. The primary aim was to focus on introducing a more collaborative best practice approach in a competitive construction environment to some 300 middle management onsite construction staff over a 4 - 5 year period. The company was seeking a partnership with an innovative tertiary provider to offer specific professional development expertise, and give effect to the company’s strategy for ongoing and accelerated growth. The delivery approach needed to have the greatest possible impact on staff in terms of engagement and knowledge transfer. How was this academic - industry partnership built? In this first part of the research, the philosophical and practical approaches, timelines applied by both parties, the steps of how the partnership was developed from the initial interviews through to the developed successful partnership are described. The preparation and delivery of this practically based, real - time bespoke programme alongside the learnings will be described in later stages of the research in a series of publications

Lack of genetic structuring, low effective population sizes and major bottlenecks characterise common and German wasps in New Zealand

Invasive species cause severe ecological and economic impacts in their introduced ranges. Vespula wasps, native to Eurasia, are a major threat to New Zealand native ecosystems. Understanding factors that influence the success of wasp invasion is pivotal for the development of control strategies. Here, we compare genetic diversity and structure of Vespula germanica and Vespula vulgaris between regions of their native and introduced ranges using microsatellite markers. Our study found lower diversity and lack of genetic structure for both invasive Vespula species within New Zealand. The significant reduction in allelic richness, gene diversity and effective population size illustrate a major bottleneck in New Zealand V. germanica and V. vulgaris populations. Strong signatures of population structure were found for both Vespula species with two clusters being identified as optimal k, approximately corresponding to the native and the invaded ranges. Our results highlight the fact that the lack of genetic diversity does not impede successful invasions in V. germanica and V. vulgaris and encourage further research into mechanisms that promote the success of invasive social insects. Overall, this study provides insights into the genetics of invasive Vespula wasps that can be useful for the development of efficient management strategies
