Patient and Healthcare Professional Satisfaction, Acceptability, and Preference Experiences With Mirikizumab Administration for Ulcerative Colitis: An International Survey.

Background: There is a need to better understand ulcerative colitis (UC) patient and healthcare provider (HCP) treatment satisfaction, acceptability, and preferences.

Methods: Two international, cross-sectional, web-based surveys were conducted among participants of a phase 3 mirikizumab study (NCT03519945). The questions captured moderate-to-severe UC patients' experience, HCPs' perception of patients' experience, and HCPs' own experience with mirikizumab administration through intravenous (IV) infusions and subcutaneous (SC) injections.

Acute nasal breathing lowers diastolic blood pressure and increases parasympathetic contributions to heart rate variability in young adults.

There is growing interest in how breathing pace, pattern, and training (e.g., device-guided or -resisted breathing) affect cardiovascular health.

Combustion products generated in simulated industrial fires.

Studies of firefighter exposure to combustion products have focused predominantly on real or simulated residential structure fires, with few investigations considering industrial fire scenarios. This study measured the atmospheric concentrations of a variety of volatile organic compounds (VOCs), acid gases, and polycyclic aromatic hydrocarbons (PAHs) produced during fires in simulated industrial premises, as well as the deposition of PAHs onto the structural firefighting ensembles worn by the firefighters involved in extinguishment activities. Ingress of these combustion products into the structural firefighting ensembles during firefighting was also measured.

16Up: Outline of a Study Investigating Wellbeing and Information and Communication Technology Use in Adolescent Twins.

The '16Up' study conducted at the QIMR Berghofer Medical Research Institute from January 2014 to December 2018 aimed to examine the physical and mental health of young Australian twins aged 16-18 years (N = 876; 371 twin pairs and 18 triplet sets). Measurements included online questionnaires covering physical and mental health as well as information and communication technology (ICT) use, actigraphy, sleep diaries and hair samples to determine cortisol concentrations. Study participants generally rated themselves as being in good physical (79%) and mental (73%) health and reported lower rates of psychological distress and exposure to alcohol, tobacco products or other substances than previously reported for this age group in the Australian population.

Evaluation of Coating Thickness Using Lift-Off Insensitivity of Eddy Current Sensor.

Defect detection in ferromagnetic substrates is often hampered by nonmagnetic coating thickness variation when using conventional eddy current testing technique. The lift-off distance between the sample and the sensor is one of the main obstacles for the thickness measurement of nonmagnetic coatings on ferromagnetic substrates when using the eddy current testing technique. Based on the eddy current thin-skin effect and the lift-off insensitive inductance (LII), a simplified iterative algorithm is proposed for reducing the lift-off variation effect using a multifrequency sensor.

Protecting Spin Coherence in a Tunable Heisenberg Model.

Using an ensemble of atoms in an optical cavity, we engineer a family of nonlocal Heisenberg Hamiltonians with continuously tunable anisotropy of the spin-spin couplings. We thus gain access to a rich phase diagram, including a paramagnetic-to-ferromagnetic Ising phase transition that manifests as a diverging magnetic susceptibility at the critical point. The susceptibility displays a symmetry between Ising interactions and XY (spin-exchange) interactions of the opposite sign, which is indicative of the spatially extended atomic system behaving as a single collective spin.

Cohort profile: the Australian genetics of depression study.

Purpose: Depression is the most common psychiatric disorder and the largest contributor to global disability. The Australian Genetics of Depression study was established to recruit a large cohort of individuals who have been diagnosed with depression at some point in their lifetime. The purpose of establishing this cohort is to investigate genetic and environmental risk factors for depression and response to commonly prescribed antidepressants.

Genome-wide association study identifies eight risk loci and implicates metabo-psychiatric origins for anorexia nervosa.

Characterized primarily by a low body-mass index, anorexia nervosa is a complex and serious illness, affecting 0.9-4% of women and 0.3% of men, with twin-based heritability estimates of 50-60%.

Exposures to air contaminants in compartment fire behavior training (CFBT) using particleboard fuel.

Firefighters are exposed to a variety of combustion products during operational fires but also during live-fire training. As part of an on-going project investigating firefighter operational and training environments, this study measured the atmospheric concentrations of volatile organic compounds and acid gases outside and inside the structural firefighting ensembles worn by instructors during compartment fire behavior training using particleboard as a fuel. Atmospheric concentrations of benzene, formaldehyde, and hydrogen cyanide within the firefighting environment were observed to exceed Australian workplace exposure standards; although, the use of self-contained breathing apparatus throughout the training meant that atmospheric concentrations measured were not representative of firefighter inhalation exposures.

PPD ACT: an app-based genetic study of postpartum depression.

Postpartum depression (PPD) is one of the most frequent complications of childbirth and particularly is suited to genetic investigation as it is more homogenous than major depression outside of the perinatal period. We developed an iOS app (PPD ACT) to recruit, consent, screen, and enable DNA collection from women with a lifetime history of PPD to sufficiently power genome-wide association studies. In 1 year, we recruited 7344 women with a history of PPD and have biobanked 2946 DNA samples from the US.

The Anorexia Nervosa Genetics Initiative (ANGI): Overview and methods.

Background: Genetic factors contribute to anorexia nervosa (AN); and the first genome-wide significant locus has been identified. We describe methods and procedures for the Anorexia Nervosa Genetics Initiative (ANGI), an international collaboration designed to rapidly recruit 13,000 individuals with AN and ancestrally matched controls. We present sample characteristics and the utility of an online eating disorder diagnostic questionnaire suitable for large-scale genetic and population research.

Nineteen and Up study (19Up): understanding pathways to mental health disorders in young Australian twins.

Purpose: The Nineteen and Up study (19Up) assessed a range of mental health and behavioural problems and associated risk factors in a genetically informative Australian cohort of young adult twins and their non-twin siblings. As such, 19Up enables detailed investigation of genetic and environmental pathways to mental illness and substance misuse within the Brisbane Longitudinal Twin Sample (BLTS).

Participants: Twins and their non-twin siblings from Queensland, Australia; mostly from European ancestry.

Diesel particulate matter and polycyclic aromatic hydrocarbons in fire stations.

Firefighters are known to be exposed to a wide variety of combustion products during operational and training firefighting activities. However, the potential for exposure to diesel exhaust emissions, recently classified as carcinogenic to humans by the International Agency for Research on Cancer, also exists within the fire station environment. In this study, concentrations of diesel particulate matter and polycyclic aromatic hydrocarbons have been measured in the engine bays, duty offices and dormitory areas of eight fire stations in Queensland, Australia.

The Anorexia Nervosa Genetics Initiative: Study description and sample characteristics of the Australian and New Zealand arm.

Objectives: Anorexia nervosa is a severe psychiatric disorder with high mortality rates. While its aetiology is poorly understood, there is evidence of a significant genetic component. The Anorexia Nervosa Genetics Initiative is an international collaboration which aims to understand the genetic basis of the disorder.

Use of sputtered zinc oxide film on aluminium foil substrate to produce a flexible and low profile ultrasonic transducer.

A flexible and low profile ultrasonic transducer was fabricated for non-destructive testing (NDT) applications by DC sputtering of 3 μm thick, c-axis oriented, ZnO film on 50 μm aluminium foil. Due to the thin foil-based construction, the transducer can be applied to curved objects and used in sites of restricted accessibility. The device has been used to demonstrate detection of simulated defects in a 45 mm diameter steel pipe, and for thickness measurement on a 3.

The effect of video review of resident laparoscopic surgical skills measured by self- and external assessment.

Background: Video review of surgical skills is an educational modality that allows trainees to reflect on self-performance. The purpose of this study was to determine whether resident and attending assessments of a resident's laparoscopic performance differ and whether video review changes assessments.

Methods: Third-year surgery residents were invited to participate.

Enterovirus-Specific Anti-peptide Antibodies.

Enterovirus 71 (EV-71) is the main causative agent of hand, foot, and mouth disease (HFMD) which is generally regarded as a mild childhood disease. In recent years, EV71 has emerged as a significant pathogen capable of causing high mortalities and severe neurological complications in large outbreaks in Asia. A formalin-inactivated EV71 whole virus vaccine has completed phase III trial in China but is currently unavailable clinically.

Firefighting instructors' exposures to polycyclic aromatic hydrocarbons during live fire training scenarios.

Cumulative exposures of firefighting instructors to toxic contaminants generated from live-fire training potentially far exceed firefighter exposures arising from operational fires. This study measured the atmospheric concentrations of polycyclic aromatic hydrocarbons (PAHs) outside and inside the structural firefighting ensembles worn by instructors during five live fire training evolutions. In addition, the contamination of ensembles by deposition of PAHs was characterized.

Structural Fire Fighting Ensembles: Accumulation and Off-gassing of Combustion Products.

Firefighters may be exposed to toxic combustion products not only during fire fighting operations and training, but also afterwards as a result of contact with contaminated structural fire fighting ensembles. This study characterized the deposition of polycyclic aromatic hydrocarbons (PAHs) onto structural fire fighting ensembles and off-gassing of combustion products from ensembles after multiple exposures to hostile structural attack fire environments. A variety of PAHs were deposited onto the outer layer of structural fire fighting ensembles, with no variation in deposition flux between new ensembles and already contaminated ensembles.

Analysis of outcomes for single-incision laparoscopic surgery (SILS) right colectomy reveals a minimal learning curve.

Background: Single-incision right colectomy has emerged as a safe and feasible alternative to standard laparoscopic resection. As with any new surgical approach, definition of the number of procedures required to optimize the technique is an important goal. Data on this learning curve for single-incision right colectomy are lacking; therefore, we report the outcomes of consecutive single-incision right colectomies to identify the procedural learning curve.

Iliac venous pressure estimates central venous pressure after laparotomy.

Background: Central venous pressure (CVP) is traditionally obtained through subclavian or internal jugular central catheters; however, many patients who could benefit from CVP monitoring have only femoral lines. The accuracy of illiac venous pressure (IVP) as a measure of CVP is unknown, particularly following laparotomy.

Methods: This was a prospective, observational study.

Caregivers of children with a disorder of sex development: associations between parenting capacities and psychological distress.

Objective: Caregivers of children with a disorder of sex development (DSD) are at increased risk for maladaptive parenting capacities, such as high levels of parental overprotection and perceived vulnerability of their child, in addition to parenting stress. The current study aims to examine whether there are relationships between these parenting capacities and psychological distress, including depressive and anxious symptoms.

Patients And Methods: Participants included 134 caregivers of 90 children with a DSD.
