A survey for variable young stars with small telescopes – VIII. Properties of 1687 Gaia selected members in 21 nearby clusters

The Hunting Outbursting Young Stars (HOYS) project performs long-term, optical, multi-filter, high cadence monitoring of 25 nearby young clusters and star forming regions. Utilising Gaia DR3 data we have identified about 17000 potential young stellar members in 45 coherent astrometric groups in these fields. Twenty one of them are clear young groups or clusters of stars within one kiloparsec and they contain 9143 Gaia selected potential members. The cluster distances, proper motions and membership numbers are determined. We analyse long term (≈ 7 yr) V, R, and I-band light curves from HOYS for 1687 of the potential cluster members. One quarter of the stars are variable in all three optical filters, and two thirds of these have light curves that are symmetric around the mean. Light curves affected by obscuration from circumstellar materials are more common than those affected by accretion bursts, by a factor of 2 – 4. The variability fraction in the clusters ranges from 10 to almost 100 percent, and correlates positively with the fraction of stars with detectable inner disks, indicating that a lot of variability is driven by the disk. About one in six variables shows detectable periodicity, mostly caused by magnetic spots. Two thirds of the periodic variables with disk excess emission are slow rotators, and amongst the stars without disk excess two thirds are fast rotators – in agreement with rotation being slowed down by the presence of a disk

Impact of pain location, organ system and treating speciality on timely delivery of analgesia in emergency departments

Objective: This retrospective, observational cohort study investigated whether the clinical features of a patient's pain, including anatomical location, organ system and likely treating speciality, impact on the delivery of analgesia within 30 min in EDs. Methods: Data were obtained from 24 centres across Australia between April 2008 and March 2009. Principal outcome was delivery of analgesia within 30 min or less. Factors that might explain any differences were analysed, including anatomical location of the pain, likely treating speciality, organ system affected, age, sex, day and time of presentation, hospital location, documented pain score and triage category. Analysis was by the χ²-test for independence of proportions and multiple logistic regression. A P-value <0.05 was considered statistically significant. Results: There were 4598 patients, of whom 2578 were male. The median age was 36 years (range 0-103). Both limb origin of pain (χ²= 46.1, P < 0.001) and documentation of a pain score (χ²= 48.6, P < 0.001) were strongly associated with delivery of analgesia within 30 min. Attending a rural ED was a significant risk factor for delayed analgesia (χ²= 12.5, P < 0.001). Burns patients (40.2%, 47 of 117, P < 0.001) and orthopaedic patients (26.1%, 259 of 992, P < 0.001) were much more likely to received analgesia within 30 min than the mean (19.5%, 896 of 4598). Conclusions: Patients presenting with burns, orthopaedic conditions or with a limb location of pain are more likely to receive analgesia within 30 min in Australian EDs. Clinicians should be aware of possible trends in the delivery of timely analgesia to patients with pain

Manaaki - a cognitive behavioral therapy mobile health app to support people experiencing gambling problems: a randomized control trial protocol

BACKGROUND: The low utilisation of current treatment services by people with gambling problems highlights the need to explore new modalities of delivering treatment interventions. This protocol presents the design of a pragmatic randomized control trial aimed at assessing the effectiveness and acceptability of cognitive behavioral therapy (CBT) delivered via a mobile app for people with self-reported gambling problems. METHODS: An innovative CBT mobile app, based on Deakin University's GAMBLINGLESS online program, has been adapted with end-users (Manaaki). Six intervention modules have been created. These are interwoven with visual themes to represent a journey of recovery and include attributes such as avatars, videos, and animations to support end-user engagement. An audio facility is used throughout the app to cater for different learning styles. Personalizing the app has been accomplished by using greetings in the participant's language and their name (e.g. Kia ora Tāne) and by creating personalized feedback. A pragmatic, randomized control two-arm single-blind trial, will be conducted in New Zealand. We aim to recruit 284 individuals. Eligible participants are ≥18 years old, seeking help for their gambling, have access to a smartphone capable of downloading an app, able to understand the English language and are willing to provide follow-up information at scheduled time points. Allocation is 1:1, stratified by ethnicity, gender, and gambling symptom severity based on the Gambling Symptom Assessment Scale (G-SAS). The intervention group will receive the full mobile cognitive behavioural programme and the waitlist group will receive a simple app that counts down the time left before they have access to the full app and the links to the data collection tools. Data collection for both groups are: baseline, 4-, 8-, and 12-weeks post-randomisation. The primary outcome is a change in G-SAS scores. Secondary measures include changes in gambling urges, frequency, expenditure, and readiness to change. Indices of app engagement, utilisation and acceptability will be collected throughout the delivery of the intervention. DISCUSSION: If effective, this study will contribute to the improvement of health outcomes for people experiencing gambling problems and have great potential to reach population groups who do not readily engage with current treatment services.
