Public health rapid response in managing COVID-19 outbreaks in residential aged care facilities: a regional public health unit perspective.

We describe here the impact of managing coronavirus disease 2019 (COVID-19) outbreaks, during January-August 2022, in residential aged care facilities (RACFs) in Central Queensland, Australia, following the deployment of a public health rapid response team (PHRRT, comprising a medical officer, a communicable disease nurse, and an epidemiologist) from a regional public health unit (PHU). Our existing vaccine preventable diseases surveillance framework was used in identifying any symptomatic resident, triggering a PHRRT response. We found that the Hospital in the Home (HiTH) admission and death events were significantly lower after the introduction of the PHRRT than in the outbreaks that occurred before.

Bridging the divide: supporting and mentoring trainees to conceptualize, plan, and integrate engagement of people with lived experience in health research.

Health researchers are encouraged by governments, funders, and journals to conduct research in partnership with people with lived experience. However, conducting research with authentic engagement and partnership with those who are experts by experience, but may not have research methods training, requires resources and specialized skills. The McMaster Collaborative for Health and Aging developed a fellowship program for trainees that builds their capacity to conduct research in partnership with older adults with relevant lived experience.

Methods: We evaluated the app's user experience and examined whether the introduction of 'PenCS Flu Topbar' in medical practices could improve the coverage of NIP-funded influenza vaccinations. We conducted a mixed-method study including a qualitative analysis of in-depth interviews with key end-users and a quantitative analysis of influenza vaccine administrative data.

Quantifying the Consistency and Characterizing the Confidence of Coronal Holes Detected by Active Contours Without Edges (ACWE).

Coronal Holes (CHs) are regions of open magnetic-field lines, resulting in high-speed solar wind. Accurate detection of CHs is vital for space-weather prediction. This paper presents an intramethod ensemble for coronal-hole detection based on the Active Contours Without Edges (ACWE) segmentation algorithm.

Frequent hospital presenters' use of health information during COVID-19: results of a cross-sectional survey.

Background: High-frequency hospital users often present with chronic and complex health conditions and are at increased risk of serious morbidity and mortality if they contract COVID-19. Understanding where high-frequency hospital users are sourcing their information, whether they understand what they find, and how they apply the information to prevent the spread of COVID-19 is essential for health authorities to be able to target communication approaches.

Methods: Cross-sectional survey of 200 frequent hospital users (115 with limited English proficiency) informed by the WHO's "Rapid, simple, flexible behavioral insights on COVID-19".

Outbreak of SARS-CoV-2 Delta variant on a single liquified natural gas (LNG) vessel, with estimates of vaccine effectiveness.

In August 2021, there was an outbreak of severe acute respiratory syndrome corona virus-2 (SARS-CoV-2) Delta variant on an international liquified natural gas (LNG) vessel offshore to Gladstone, Queensland. Fourteen of the 26 crew members aboard the vessel tested positive for SARS-COV-2 on PCR during the outbreak. Vaccine effectiveness (VE) was 52% for all lab-confirmed SARS-CoV-2 infections, 65% for symptomatic SARS-CoV-2 infection and 100% for severe SARS-CoV-2.

"Scary to get, more scary not to": COVID-19 vaccine acceptance among healthcare workers in Central Queensland, Australia, a cross-sectional survey.

Background: Behavioural and social drivers (BeSD) of coronavirus disease 2019 (COVID-19) vaccine acceptance among Australian healthcare workers (HCW) living and working in regional areas are not well studied. Understanding local HCWs' COVID-19 risk perceptions and potential barriers to COVID-19 vaccine uptake is crucial in supporting rollout. We aimed to understand the COVID-19 vaccine drivers among HCW in Central Queensland (CQ), Australia.

Effect of 2,6-xylidine (DMA) on secretion of biomarkers for inflammation and neurodevelopment by the placenta.

Cigarette smoke enhances placental inflammation and interferes with steroidogenesis. However, the chemicals in the smoke responsible for these biological activities are unclear. 2,6 xylidine (also called 2,6 Dimethylaniline, DMA) is a component of cigarette smoke that has carcinogenic properties but its effects on the placenta are unknown.

A norovirus gastroenteritis outbreak in an Australian child-care center: A household-level analysis.

There is a large burden of norovirus disease in child-care centers in Australia and around the world. Despite the ubiquity of norovirus outbreaks in child-care centers, little is known about the extent of this burden within the child-care center and the surrounding household clusters. Therefore, we performed an in-depth analysis of a gastroenteritis outbreak to examine the patterns of transmissions, household attack rates and the basic reproduction number (R0) for Norovirus in a child-care facility.

Measuring the economic impact of hospital-acquired complications on an acute health service.

Objective This study determined the economic impact of 16 'high-priority' hospital-acquired complications (HACs), as defined by the Australian Commission on Safety and Quality in Health Care, from the perspective of an individual Australian health service. Methods A retrospective cohort study was performed using a deidentified patient dataset containing 93056 in-patient separations in Northern Health (Victoria, Australia) from 1 July 2016 to 30 June 2017. Two log-linked generalised linear regression models were used to obtain additional costs and additional length of stay (LOS) for 16 different HACs, with the main outcome measures being the additional cost and LOS for all 16 HACs.

Continuous pulse oximetry during skin-to-skin care: An Australian initiative to prevent sudden unexpected postnatal collapse.

Aim: To examine the use of continuous pulse oximetry monitoring (CPOM) of newborns as a non-invasive and non-intrusive standard of care for promoting early and safe skin-to-skin contact between mothers and newborns immediately after birth and to gather acceptability feedback from midwifery staff and mothers.

Methods: All babies receiving skin-to-skin contact (SSC) had continuous pulse oximetry monitoring (CPOM) for the first-hour postbirth. Staff were trained with education sessions before implementation.

Evaluation of the effectiveness of a comprehensive care plan to reduce hospital acquired complications in an Australian hospital: protocol for a mixed-method preimplementation and postimplementation study.

Introduction: A new healthcare standard (Standard 5: Comprehensive Care) has been introduced by the Australian Commission on Safety and Quality in Healthcare. Standard 5 advocates for organisational leadership to develop and maintain systems and processes to deliver patient-centred comprehensive care plans that include appropriate screening to identify and mitigate risks associated with hospitalisation. The aim of this study is to evaluate the effectiveness and cost effectiveness of a comprehensive care and risk evaluation (Comprehensive Assessment and Risk Evaluation (CARE)) plan to reduce hospital acquired complications (HACs) in an Australian hospital network.

COVID-19 and paediatric health services: A survey of paediatric physicians in Australia and New Zealand.

Aims: COVID-19 is now a global pandemic. At the time of survey, fewer than 150 children in Australia and New Zealand had documented infection. The aim of this study was to assess attitudes, readiness and confidence in the early stages of the COVID-19 pandemic through an online survey of paediatric physicians and sub-specialists across Australia and New Zealand.

In-Situ Simulation Enhances Emergency Preparedness in Pediatric Care Practices.

Background It is not uncommon for emergencies to present at primary care offices. As such, it is necessary for those offices to be prepared to handle, at a minimum, the most common types of emergencies. Objective To evaluate the effectiveness of in-situ simulation training in improving emergency preparedness within pediatric primary care settings.

Effects of tributyltin on placental cytokine production.

Objective Tributyltin (TBT) is a persistent pollutant but its effects on placental function are poorly understood as are its possible interactions with infection. We hypothesized that TBT alters the production of sex hormones and biomarkers for inflammation and neurodevelopment in an infection-dependent manner. Methods Placental explant cultures were treated with 0-5000 nM TBT in the presence and absence of Escherichia coli.

Papular Acne Scars of the Nose and Chin: An Under-recognised Variant of Acne Scarring.

Background: Scarring following acne vulgaris is common and can be of profound psychosocial consequence.

Aims And Objectives: We have clinically noted a variant of acne scarring, overlooked by previous categorisation schemes, which we have denominated as papular acne scars of the nose and chin. We sought to characterise these novel entities further.

Automated survey of 8000 plan checks at eight facilities.

Purpose: To identify policy and system related weaknesses in treatment planning and plan check work-flows.

Methods: The authors' web deployed plan check automation solution, PlanCheck, which works with all major planning and record and verify systems (demonstrated here for mosaiq only), allows them to compute violation rates for a large number of plan checks across many facilities without requiring the manual data entry involved with incident filings. Workflows and failure modes are heavily influenced by the type of record and verify system used.

The Role of CT cholangiography in the Detection and Localisation of Suspected Bile Leakage Following Cholecystectomy.

Background: Most bile duct injuries are not recognized at the time of initial surgery. Optimal treatment requires early recognition. CT IVC has become increasingly important in identifying bile leaks and their source after cholecystectomy.

Reducing the low-dose lung radiation for central lung tumors by restricting the IMRT beams and arc arrangement.

To compare the extent to which 7 different radiotherapy planning techniques for mediastinal lung targets reduces the lung volume receiving low doses of radiation. Thirteen non-small cell lung cancer patients with targets, including the mediastinal nodes, were identified. Treatment plans were generated to both 60- and 74-Gy prescription doses using 7 different planning techniques: conformal, hybrid conformal/intensity-modulated radiation treatment (IMRT), 7 equidistant IMRT beams, 2 restricted beam IMRT plans, a full (360°) modulated arc, and a restricted modulated arc plan.

Comparison of computed tomography scout based reference point localization to conventional film and axial computed tomography.

Identification of source positions after implantation is an important step in brachytherapy planning. Reconstruction is traditionally performed from films taken by conventional simulators, but these are gradually being replaced in the clinic by computed tomography (CT) simulators. The present study explored the use of a scout image-based reconstruction algorithm that replaces the use of traditional film, while exhibiting low sensitivity to metal-induced artifacts that can appear in 3D CT methods.

A systems biology approach to invasive behavior: comparing cancer metastasis and suburban sprawl development.

Background: Despite constant progress, cancer remains the second leading cause of death in the United States. The ability of tumors to metastasize is central to this dilemma, as many studies demonstrate successful treatment correlating to diagnosis prior to cancer spread. Hence a better understanding of cancer invasiveness and metastasis could provide critical insight.
