Abstract Reports of Guillain-Barré syndrome (GBS) have emerged during the Coronavirus disease 2019 (COVID-19) pandemic. This epidemiological and cohort study sought to investigate any causative association between COVID-19 infection GBS. The epidemiology GBS cases reported UK National Immunoglobulin Database was studied from 2016 compared Data were stratified by hospital trust region, with numbers per month. population data for collated public health bodies. In parallel, but separately,...
Abstract Aims To describe (i) self‐reported changes in drug use and (ii) trends price, perceived availability, purity of illicit drugs, among people who regularly ecstasy/ 3,4‐methylenedioxymethamphetamine (MDMA) other stimulants Australia following COVID‐19 associated restrictions. Design Annual interviews with cross‐sectional sentinel samples conducted face‐to‐face 2016–19 via video conferencing or telephone 2020. Data were collected an interviewer‐administered structured questionnaire....
Machine learning (ML) has emerged as a superior method for the analysis of large datasets. Application ML is often hindered by incompleteness data which particularly evident when approaching disease screening due to varied testing regimens across medical institutions. Here we explored utility multiple algorithms predict cancer risk trained using but incomplete real-world dataset tumor marker (TM) values.TM were collected from asymptomatic cohort (n = 163,174) at two independent centers. The...
Changes to drug markets can affect use and related harms. We aimed describe market trends of heroin, methamphetamine, cocaine ecstasy in Australia following the introduction COVID-19 pandemic-associated restrictions. Australians residing capital cities who regularly inject drugs (n ∼= 900 each year) or and/or other illicit stimulants 800 participated annual interviews 2014-2022. used self-reported indicators (price, availability, purity) for crystal cocaine, estimate generalised additive...
Several studies have reported evidence of interference between respiratory viruses: viruses rarely reach their epidemic peak concurrently and there appears to be a negative association infection with one virus co-infection another. We used results spanning 16 years (2002-2017) routine diagnostic multiplex panel that tests for nine further investigate these interactions in Victoria, Australia. Time series analyses were plot the proportion positive each virus. The seasonality all included was...
Abstract Introduction To describe trends in methamphetamine use, markets and harms Australia from 2003 to 2019. Methods Data comprised patterns of use price sentinel samples people who inject drugs MDMA/other illicit stimulants population‐level amphetamine‐related police seizures, arrests, hospitalisations, treatment episodes deaths approximately Bayesian autoregressive time‐series models were analysed for: no change; constant rate change over time differing after one three changepoints....
Abstract Introduction Vaccine acceptability is a key determinant of vaccination uptake. Despite being at risk adverse outcomes from coronavirus‐19 disease (COVID‐19), COVID‐19 vaccine among people who inject drugs unknown. We surveyed in Melbourne, Australia to assess potential uptake vaccines prior distribution. Methods Cross‐sectional study, comprising interviewer‐administered structured telephone interviews completed 30 November 22 December 2020 Australia. Participants were aged 18 years...
Abstract Introduction This paper aims to describe cocaine use, markets and harms in Australia from 2003 2019. Methods Outcome indicators comprised prevalence of use triennial household surveys; patterns annual surveys sentinel samples who stimulants; cocaine‐related seizures, arrests, hospitalisations, deaths treatment episodes. Bayesian autoregressive time‐series analyses were conducted estimate trend over time: Model 1, no change; 2, constant rate 3, change time differing after one point....
Abstract Background In Australia, seasonal inactivated influenza vaccine is typically offered in April. However, the onset, peak and end of a typical season vary, optimal timing for vaccination remains unclear. Here, we investigated vaccine‐induced antibody response kinetics over 6 months different age groups. Methods We conducted prospective serosurvey among 71 adults aged 18–50 years, 15 community‐dwelling (‘healthy’) 16 aged‐care facility resident (‘frail’) older ≥65 years who received...
People who inject drugs may be at higher risk of COVID-19 transmission and more severe negative health outcomes following infection. Early research on hypothetical vaccines suggests this population less likely to accept vaccination. This commentary extends by presenting vaccine intention data from Illicit Drug Reporting System interviews conducted in June-July 2021, the early stages rollout, with people Australia (N = 888). Half sample (48%, n 419) reported that they were hesitant receive...
Polysubstance use is associated with negative health and social outcomes among people who inject drugs. We aimed to describe trends in polysubstance identify psychosocial correlates drug risk behaviours. defined as intentional same day of more than one three classes: opioids, other non-opioid depressants (hereafter 'depressants'), stimulants.We used 10 years (2012-2022, excluding 2020) data from annual surveys Australian capital cities drugs (N=5657) construct five mutually exclusive...
As part of its role in the World Health Organization's (WHO) Global Influenza Surveillance and Response System (GISRS), WHO Collaborating Centre for Reference Research on Melbourne received a total 3993 human influenza-positive samples during 2018. Viruses were analysed their antigenic, genetic antiviral susceptibility properties. Selected viruses propagated qualified cells or hens' eggs use as potential seasonal influenza vaccine virus candidates. In 2018, A(H1)pdm09 predominated over A(H3)...
Analyses are presented of model simulations and Lagrangian drifter experiments designed to quantify circulation dispersal in Tasman Golden Bays, their connection Cook Strait, New Zealand. Observations made autumn 2017 summer 2018 compared with numerical results. The were focussed on three repeat each bay measure the local horizontal eddy diffusivity. An additional experiment investigated with, flow through, Greater Strait. Point by point velocities extracted from show low correlation but...
