Abstract
BACKGROUND Allergic asthma is a chronic airway inflammatory disease involving the complementary actions of innate and adaptive immune responses. Endogenously generated cannabinoids acting via CB2 receptors play important roles in both homeostatic and inflammatory processes. However, the contribution of CB2-acting eicosanoids to the innate events preceding sensitization to the common house dust mite (HDM) allergen remains to be elucidated. We investigated the role of CB2 activation during allergen-induced pulmonary inflammation and natural killer (NK) cell effector function. METHODS Lung mucosal responses in CB2-deficient (CB2-/- ) mice were examined and compared with wild-type (WT) littermates following intranasal exposure to HDM allergen. RESULTS Mice lacking CB2 receptors exhibited elevated numbers of pulmonary NK cells yet were resistant to the induction of allergic inflammation exemplified by diminished airway eosinophilia, type 2 cytokine production and mucus secretion after allergen inhalation. This phenomenon was corroborated when WT mice were treated with a CB2-specific antagonist that caused a pronounced inhibition of HDM-induced airway inflammation and goblet cell hyperplasia. Unexpectedly, the preponderance of NK cells in the lungs of CB2-/- mice correlated with reduced numbers of group 2 innate lymphoid cells (ILC2s). Depletion of NK cells restored the allergen responsiveness in the lungs and was associated with elevated ILC2 numbers. CONCLUSIONS Collectively, these results reveal that CB2 activation is crucial in regulating pulmonary NK cell function, and suggest that NK cells serve to limit ILC2 activation and subsequent allergic airway inflammation. CB2 inhibition may present an important target to modulate NK cell response during pulmonary inflammation.

Abstract
BACKGROUND Spinal fractures are typically considered a contraindication to mechanical diagnosis and therapy (MDT). OBJECTIVE AND IMPORTANCE The purpose of this case study is to illustrate how MDT was used safely and effectively to treat lumbar pain in a patient with multiple lumbar transverse process fractures. CLINICAL PRESENTATION The subject was a 24-year-old female with left L2-5 transverse process fractures, sustained 10 weeks prior in a pedestrian versus motor vehicle accident. INTERVENTION AND TECHNIQUE After collaboration with her physiatrist, an MDT examination revealed a presentation consistent with the lumbar derangement syndrome. CONCLUSION After three visits, utilizing patient generated forces with the extension principle of treatment, her pain, Oswestry disability index (ODI) score, and function all improved.

Abstract
The benchmark against which nurse-academics are primarily judged remains scholarly productivity. This study sought to examine levels of scholarly productivity amongst Australian nurse academics: where they are putting their emphasis, and what progress they are making. This quantitative study used a questionnaire survey technique that identified individual items of scholarship over a two-year period. The use of two author-developed rating scales, the General Scholarship Index (GSI) and the DEST Scholarship Index (DSI) enabled a comparison of nurse academics with other academic disciplines. Findings from the study underscore the positive association between academic rank, qualifications and scholarly productivity. To facilitate increasing the latter to a level comparable with other disciplines, nurse academics may need to refocus their energies on DEST approved activities. A work climate more conducive to fostering the ethos and skills of academic scholarly productivity is needed.

Abstract
INTRODUCTION Consensus is lacking in determining appropriate outcome measures for assessment of childhood obesity treatments. Inconsistency in the use and reporting of such measures impedes comparisons between treatments and limits consideration of effectiveness. This study aimed to produce a framework of recommended outcome measures: the Childhood obesity treatment evaluation Outcomes Review (CoOR) framework. METHODS A systematic review including two searches was conducted to identify (1) existing trial outcome measures and (2) manuscripts describing development/evaluation of outcome measures. Outcomes included anthropometry, diet, eating behaviours, physical activity, sedentary time/behaviour, fitness, physiology, environment, psychological well-being and health-related quality of life. Eligible measures were appraised by the internal team using a system developed from international guidelines, followed by appraisal from national external expert collaborators. RESULTS A total of 25,486 papers were identified through both searches. Eligible search 1 trial papers cited 417 additional papers linked to outcome measures, of which 56 were eligible. A further 297 outcome development/evaluation papers met eligibility criteria from search 2. Combined, these described 191 outcome measures. After internal and external appraisal, 52 measures across 10 outcomes were recommended for inclusion in the CoOR framework. CONCLUSION Application of the CoOR framework will ensure greater consistency in choosing robust outcome measures that are appropriate to population characteristics.

Abstract
We demonstrate a polarization-managed 8-dimensional modulation format that is time domain coded to reduce inter-channel nonlinearity. Simulation results show a 2.3 dB improvement in maximum net system margin (NSM) relative to polarization multiplexed (PM)-BPSK, and a 1.0 dB improvement relative to time interleaved return-to-zero (RZ)-PM-BPSK, for five WDM channels propagating over 1600 km ELEAF with 90% inline optical dispersion compensation. In contrast to the other modulations considered, the new 8-dimensional format has negligible sensitivity to the polarization states of the neighboring WDM channels. High-density WDM (HD-WDM) measurements on a 5000 km dispersion-managed link show a 1.0 dB improvement in net system margin relative to PM-BPSK.
