Trends in the healthiness and nutrient composition of packaged products sold by major food and beverage companies in New Zealand 2015 to 2019.

Background: Dietary risk factors are the leading cause of death globally and in New Zealand (NZ). Processed packaged foods are prevalent in the food supply and contribute excess amounts of sodium, saturated fat, and sugar in diets. Improving the nutritional quality of these foods has the potential to reduce population chronic disease risk.

Awareness, support, and opinions of healthy food and drink policies: a survey of staff and visitors in New Zealand healthcare organisations.

Background: In 2016, a voluntary National Healthy Food and Drink Policy (hereafter, "the Policy") was released to encourage public hospitals in New Zealand to provide food and drink options in line with national dietary guidelines. Five years later, eight (of 20) organisations had adopted it, with several preferring to retain or update their own institutional-level version. This study assessed staff and visitors' awareness and support for and against the Policy, and collected feedback on perceived food environment changes since implementation of the Policy.

2021 Assessment of New Zealand district health boards' institutional healthy food and drink policies: the HealthY Policy Evaluation (HYPE) study.

Aim: To assess adoption of the voluntary National Healthy Food and Drink Policy (NHFDP) and the alignment of individual institutional healthy food and drink policies with the NHFDP.

Method: All 20 district health boards (DHBs) and two national government agencies participated. Policies of those organisations that had not fully adopted the NHFDP were assessed across three domains: nutrition standards; promotion of a healthy food and beverages environment; and policy communication, implementation and evaluation.

Central sensitisation in chronic fatigue syndrome and fibromyalgia; a case control study.

Introduction: Chronic fatigue syndrome (CFS) and fibromyalgia (FM) are both complex conditions that are challenging to treat. This may be related to an incomplete understanding of their pathophysiology, itself obfuscated by their heterogeneity. The symptomatic overlap between them and their common comorbidity suggests a shared vulnerability, which might be explained by central sensitisation.

Cost and greenhouse gas emissions of current, healthy, flexitarian and vegan diets in Aotearoa (New Zealand).

Objective: To compare the costs and climate impact (greenhouse gas emissions) associated with current and healthy diets and two healthy and environmentally friendly dietary patterns: flexitarian and vegan.

Design: Modelling study.

Setting: Aotearoa (New Zealand).

The Scottish police caution: do individuals with intellectual disabilities understand a verbally presented police caution, and can comprehension be improved?

This study considers comprehension of the Scottish police caution amongst people with an intellectual disability ( = 30). It applies techniques to the caution that are suggested to increase its 'listenability', to examine whether this could be a successful method of improving understanding. These techniques include providing instructions, further explanations and listing information.

The effect of surfactant on the dissolution of porcine pulpal tissue by sodium hypochlorite solutions.

Introduction: A previous study of the relative dental pulp-dissolving abilities of Milton brand of sodium hypochlorite (NaOCl) and other surfactant-containing NaOCl solutions produced specifically for endodontic treatment showed a markedly better performance of the surfactant-containing product that was not explained by differences in active chlorine content. This study investigated whether the presence of surfactant in the NaOCl solutions was responsible for the difference in dissolution times seen in the previous study.

Methods: Circular samples 2.

Arthritis and pain. Current approaches in the treatment of arthritic pain.

Current evidence suggests that although persistent arthritic pain is initiated and maintained by articular pathology, it is also heavily influenced by a range of other factors. Strategies for treating arthritic pain are therefore different from those adopted for acute pain. Although published guidelines offer general assistance, the complexity of underlying mechanisms requires that measures designed to relieve pain must take into account individual biological, psychological and societal factors.

The differential contribution of tumour necrosis factor to thermal and mechanical hyperalgesia during chronic inflammation.

Therapies directed against tumour necrosis factor (TNF) are effective for the treatment of rheumatoid arthritis and reduce pain scores in this condition. In this study, we sought to explore mechanisms by which TNF contributes to inflammatory pain in an experimental model of arthritis. The effects of an anti-TNF agent, etanercept, on behavioural pain responses arising from rat monoarthritis induced by complete Freund's adjuvant were assessed and compared with expression of TNF receptors (TNFRs) by dorsal root ganglion (DRG) cells at corresponding time points.

Chronic upper limb pain: an exploration of the biopsychosocial model.

Objective: To model pain intensity and consequent disability by independent physical, psychological, and social variables in a group of patients with chronic upper limb pain.

Methods: We studied a group of 73 hospital outpatients with either chronic work related diffuse upper limb pain or carpal tunnel syndrome. We assessed pain intensity, disability, and personality by self-rated questionnaires; and psychiatric morbidity by a standardized interview.

Pain related behaviour in two models of osteoarthritis in the rat knee.

Osteoarthritis (OA) is a major healthcare burden, with increasing incidence. Pain is the predominant clinical feature, yet therapy is ineffective for many patients. While there are considerable insights into the mechanisms underlying tissue remodelling, there is poor understanding of the link between disease pathology and pain.

The role of inflammatory mediators on nociception and pain in arthritis.

Pain is the most common complaint of individuals with osteoarthritis but the cause of symptoms in this disorder remains unclear. Quantitative sensory testing reveals that in patients with chronic joint disease there is diffuse and persistent alteration of nociceptive (pain) pathways, irrespective of the level of activity of the underlying disease. Inflammatory mediators contribute to this plasticity either by directly activating high threshold receptors or more commonly by sensitizing nociceptive neurons to subsequent everyday stimuli.

Inhibition of inflammation and hyperalgesia in NK-1 receptor knock-out mice.

We sought to characterise the contribution of the neuropeptide substance P to the outcome of two models of footpad inflammation of differing severity. In an intense inflammatory model produced by intra-plantar Mycobacterium tuberculosus (10 mg/ml) substantial reductions in footpad swelling, histological outcome and mechanical hyperalgesia were observed from early time points in mice lacking the neurokin-1 receptor for substance P compared with wild-type controls. Conversely, in a less intense model (M.

Enhancement of angiogenesis by endogenous substance P release and neurokinin-1 receptors during neurogenic inflammation.

Early angiogenesis is a key step in the transition from acute to persistent inflammation. The nervous system has long been known to play a role in inflammation, in part through the release of substance P from peripheral nerve terminals (neurogenic inflammation). Application of substance P can stimulate vessel growth in a variety of angiogenesis assays, although it was previously not known whether endogenous substance P released from sensory nerves could modulate angiogenesis.

Illness behavior and psychosocial factors in diffuse upper limb pain disorder: a case-control study.

Objective: To compare behavioral and other psychosocial factors in patients with diffuse upper limb pain disorder (ULPD) and patients with carpal tunnel syndrome (CTS).

Methods: We compared 37 hospital outpatients with diffuse ULPD with 36 hospital outpatients with CTS, matched by sex, pain intensity, and duration of illness. We assessed psychiatric morbidity by a standardized interview, and both symptoms and personality by self-rated questionnaires.

Disease modifying and anti-nociceptive effects of the bisphosphonate, zoledronic acid in a model of bone cancer pain.

Inoculation of syngeneic MRMT-1 mammary tumour cells into one tibia of female rats produced tumour growth within the bone associated with a reduction in bone mineral density (BMD) and bone mineral content (BMC), severe radiological signs of bone destruction, together with the development of behavioural mechanical allodynia and hyperalgesia. Histological and radiological examination showed that chronic treatment with the bisphosphonate, zoledronic acid (30 microg/kg, s.c.

How does neuropathophysiology affect the signs and symptoms of spinal disease?

A complex relationship exists between back pain and the presence of spinal disease. Particularly in chronic situations, back pain and its behavioural and emotional consequences are as likely to reflect the influence of psychosocial factors as any underlying spinal pathology. Nevertheless, physical factors are clearly important and it is significant that whereas in normal discs only the outer third of the annulus fibrosus is innervated, a much more extensive innervation develops in the presence of degeneration.

Oral anti-hyperalgesic and anti-inflammatory activity of NK(1) receptor antagonists in models of inflammatory hyperalgesia of the guinea-pig.

The oral analgesic and anti-inflammatory activity of NK(1) antagonists with species preference for the human receptor were assessed in (1) the carrageenan-induced inflammatory hyperalgesia and (2) Freund's complete adjuvant (FCA)-induced extravasation in the knee joint models of the guinea-pig, respectively. Mechanical hyperalgesia was determined by measuring the withdrawal threshold to a noxious mechanical stimulus applied to the paw and thermal hyperalgesia as the withdrawal latency to a noxious thermal stimulus applied to the plantar surface. A concentration of 1.
