Effect of a Smartphone App (S-Check) on Actual and Intended Help-Seeking and Motivation to Change Methamphetamine Use Among Adult Consumers of Methamphetamine in Australia: Randomized Waitlist-Controlled Trial.

Background: Interventions are required that address delays in treatment-seeking and low treatment coverage among people consuming methamphetamine.

Objective: We aim to determine whether a self-administered smartphone-based intervention, the "S-Check app" can increase help-seeking and motivation to change methamphetamine use, and determine factors associated with app engagement.

Methods: This study is a randomized, 28-day waitlist-controlled trial.

Assessment of false discovery rate control in tandem mass spectrometry analysis using entrapment.

A pressing statistical challenge in the field of mass spectrometry proteomics is how to assess whether a given software tool provides accurate error control. Each software tool for searching such data uses its own internally implemented methodology for reporting and controlling the error. Many of these software tools are closed source, with incompletely documented methodology, and the strategies for validating the error are inconsistent across tools.

Analysis of Tandem Mass Spectrometry Data with CONGA: Combining Open and Narrow Searches with Group-Wise Analysis.

Searching for tandem mass spectrometry proteomics data against a database is a well-established method for assigning peptide sequences to observed spectra but typically cannot identify peptides harboring unexpected post-translational modifications (PTMs). Open modification searching aims to address this problem by allowing a spectrum to match a peptide even if the spectrum's precursor mass differs from the peptide mass. However, expanding the search space in this way can lead to a loss of statistical power to detect peptides.

Bridging the False Discovery Gap.

Controlling the false discovery rate (FDR) among discoveries from a tandem mass spectrometry proteomics experiment using target decoy competition (TDC) controls only the proportion of false discoveries in an average sense. Thus, for any particular analysis, even with a valid FDR control procedure, the proportion of false discoveries (the FDP) may be higher than the specified FDR threshold. We demonstrate this phenomenon using real data and describe two recently developed methods that help bridge the gap between controlling the expected or average rate of false discoveries and the empirical rate (FDP).

Group-walk: a rigorous approach to group-wise false discovery rate analysis by target-decoy competition.

Motivation: Target-decoy competition (TDC) is a commonly used method for false discovery rate (FDR) control in the analysis of tandem mass spectrometry data. This type of competition-based FDR control has recently gained significant popularity in other fields after Barber and Candès laid its theoretical foundation in a more general setting that included the feature selection problem. In both cases, the competition is based on a head-to-head comparison between an (observed) target score and a corresponding decoy (knockoff) score.

Playing at the edges, navigating sexual boundaries, and narrating sexual distress; Practices and perspectives of sexuality and gender diverse people who use GHB.

Background: Research addressing sexualised use of GHB to date has largely focussed on gay and bisexual men's GHB use in the context of chemsex, this research has highlighted risks and experiences associated with sexual violence. No studies have included people of diverse sexualities and genders and documented reported practices to ensure mutually gratifying and consensual sex in the context of sexualised drug use (SDU).

Methods: Semi-structured interviews were conducted with 31 people from sexuality and gender diverse communities living in Australia who reported three or more occasions of GHB use in the previous 12 months.

Scintillation light detection in the 6-m drift-length ProtoDUNE Dual Phase liquid argon TPC.

DUNE is a dual-site experiment for long-baseline neutrino oscillation studies, neutrino astrophysics and nucleon decay searches. ProtoDUNE Dual Phase (DP) is a 6   6   6 m liquid argon time-projection-chamber (LArTPC) that recorded cosmic-muon data at the CERN Neutrino Platform in 2019-2020 as a prototype of the DUNE Far Detector. Charged particles propagating through the LArTPC produce ionization and scintillation light.

Individual level peer interventions for gay and bisexual men who have sex with men between 2000 and 2020: A scoping review.

Background: Peer-led interventions are central to the global HIV response for gay and bisexual men who have sex with men [GBMSM]. Since the year 2000, technological advancements in HIV and an increased response to the health disparities faced by GBMSM outside of HIV, have contributed to the expanding scope of their content and delivery. This review sets out to characterise the evidence base for individual level peer interventions for GBMSM, overview approaches to implementing and evaluating them and identify future priorities for their delivery and evaluation.

Controlling for pleasure and risk: The experiences of sexuality and gender diverse people who use GHB.

Background: GHB is used among some sexuality and gender diverse populations at elevated rates, however little qualitative research has explored GHB use among these populations with regards to diverse contexts, settings, practices, and experiences of use. Internationally, harms relating to GHB overdose appear to be increasing. Research outlining consumers' experiences of GHB-related pleasures and their strategies to reduce harms may inform GHB education and intervention responses.

Prospects for beyond the Standard Model physics searches at the Deep Underground Neutrino Experiment: DUNE Collaboration.

The Deep Underground Neutrino Experiment (DUNE) will be a powerful tool for a variety of physics topics. The high-intensity proton beams provide a large neutrino flux, sampled by a near detector system consisting of a combination of capable precision detectors, and by the massive far detector system located deep underground. This configuration sets up DUNE as a machine for discovery, as it enables opportunities not only to perform precision neutrino measurements that may uncover deviations from the present three-flavor mixing paradigm, but also to discover new particles and unveil new interactions and symmetries beyond those predicted in the Standard Model (SM).

Contemporary Darwinism as a worldview.

The most public-facing forms of contemporary Darwinism happily promote its worldview ambitions. Popular works, by the likes of Richard Dawkins, deflect associations with eugenics and social Darwinism, but also extend the reach of Darwinism beyond biology into social policy, politics, and ethics. Critics of the enterprise fall into two categories.

The sector is ready, and the community needs Australian alcohol and other drug treatment services to ask about sexuality and gender identity.

Sexuality and gender diverse Australians are a priority population in federal and state-based alcohol and other drug (AOD) strategies. Research evidence shows higher prevalence of AOD use by lesbian, gay, bisexual, transgender and queer (LGBTQ) people, riskier use and a higher proportion have accessed AOD treatment. Despite these disparities, Australian AOD treatment services do not routinely collect data on sexuality or gender identity.

User redesign, testing and evaluation of the Monitoring Risk and Improving System Safety (MoRISS) checklist for the general practice work environment.

Background: Inadequate checking of safety-critical issues can compromise care quality in general practice (GP) work settings. Adopting a systemic, methodical approach may lead to improved standardisation of processes and reliability of task performance, strengthening the safety systems concerned. This study aimed to revise, modify and test the content and relevance of a previously validated safety checklist to the current GP context.

Participatory design of an improvement intervention for the primary care management of possible sepsis using the Functional Resonance Analysis Method.

Background: Ensuring effective identification and management of sepsis is a healthcare priority in many countries. Recommendations for sepsis management in primary care have been produced, but in complex healthcare systems, an in-depth understanding of current system interactions and functioning is often essential before improvement interventions can be successfully designed and implemented. A structured participatory design approach to model a primary care system was employed to hypothesise gaps between work as intended and work delivered to inform improvement and implementation priorities for sepsis management.

Air sampling in the breathing zone of neonatal foals for prediction of subclinical Rhodococcus equi infection.

Reasons For Performing The Study: Disease caused by Rhodococcus equi is a significant burden to the horse breeding industry worldwide. Early detection of rhodococcal pneumonia, albeit important to minimise treatment costs, is difficult because of the insidious nature of the disease and the lack of definitive diagnostic tests.

Objectives: To investigate air sampling from the breathing zone of neonatal foals as a predictor of subsequent rhodococcal pneumonia.

Kernicterus in a neonatal foal.

A 5-day-old Thoroughbred foal was submitted to the necropsy service at the University of Kentucky Livestock Disease Diagnostic Center. The foal had a clinical history of seizure activity and severe icterus. A complete blood count and serum chemistry analysis indicated that the foal was anemic (hematocrit, 16%), hyperbilirubinemic (45 mg/dl), and hypoglycemic.

An innovative strategy for institutionalizing a community-based tobacco program.

When Proposition 99 tobacco control program funding to state health departments was reduced in 1993, Contra Costa County developed a strategy to institutionalize its tobacco control programs in other organizations. This effort identified seven funding priorities and three stable, experienced community organizations "adopted" these priorities.

The Healthy Neighborhoods Project: a local health department's role in catalyzing community development.

Studies show that community development approaches to health education may lead not only to improved social, economic, and health status but also to increased individual participation in health education and preventive health care activities. However, because of categorical funding restraints and philosophical issues, local health departments have rarely given control of defining project outcomes to the community. One such project was in a low-income urban neighborhood in the San Francisco Bay Area.

Idiopathic hypocalcemia in foals.

Five thoroughbred foals (4 fillies and 1 colt), all in good to excellent body condition, ranging in age from 4 days to 5 weeks at the time of onset of signs, were presented to 2 Kentucky equine hospitals from 1992 through 1996. All 5 foals presented with tachycardia, hyperhidrosis, diarrhea or a recent history of diarrhea, and muscle rigidity or stiff gait. Four of the 5 foals presented for recumbency, seizure-like activity with opisthotonos, or pronounced extensor muscle rigidity.

Seminal vesiculitis as a cause of signs of colic in a stallion.

A 5-year-old stallion was referred because of signs of abdominal pain. During the initial examination, signs of pain were elicited when the right seminal vesicle was palpated per rectum. Signs of pain were also elicited during sexual arousal and attempts at semen collection.

Miscellaneous conditions of the equine head.

Nutritional secondary hyperparathyroidism is associated with horses that are fed diets with an imbalance of calcium and phosphorus or diets containing oxalates. Clinical signs include a shifting lameness, with tenderness of the joints, reluctance to move, or a stiff, stilted gait. Some horses may have broadening of the nasal bones, enlargement of the maxilla and/or the mandible, or a ridge over the nasal bones.
