Automating population dose survey processing-An Australian feasibility study.

Background: A comprehensive collection of data on doses in adult computed tomography procedures in Australia has not been undertaken for some time. This is largely due to the effort involved in collecting the data required for calculating the population dose. This data collection effort can be greatly reduced, and the coverage increased, if the process can be automated without major changes to the workflow of the imaging facilities providing the data.

The effects of radiofrequency exposure on cognition: A systematic review and meta-analysis of human observational studies.

Background: We aimed to assess evidence of long-term effects of exposure to radiofrequency (RF) electromagnetic fields (EMF) on indicators of cognition, including domains of learning and memory, executive function, complex attention, language, perceptual motor ability and social cognition, and of an exposure-response relationship between RF-EMF and cognition.

Methods: We searched PubMed, Embase, PsycInfo and the EMF-Portal on September 30, 2022 without limiting by date or language of publication. We included cohort or case-control studies that evaluated the effects of RF exposure on cognitive function in one or more of the cognitive domains.

Measuring dose in lung identifies peripheral tumour dose inaccuracy in SBRT audit.

Purpose: Stereotactic Body Radiotherapy (SBRT) for lung tumours has become a mainstay of clinical practice worldwide. Measurements in anthropomorphic phantoms enable verification of patient dose in clinically realistic scenarios. Correction factors for reporting dose to the tissue equivalent materials in a lung phantom are presented in the context of a national dosimetry audit for SBRT.

Adoption of respiratory motion management in radiation therapy.

Background And Purpose: A survey on the patterns of practice of respiratory motion management (MM) was distributed to 111 radiation therapy facilities to inform the development of an end-to-end dosimetry audit including respiratory motion.

Materials And Methods: The survey (distributed via REDCap) asked facilities to provide information specific to the combinations of MM techniques (breath-hold gating - BHG, internal target volume - ITV, free-breathing gating - FBG, mid-ventilation - MidV, tumour tracking - TT), sites treated (thorax, upper abdomen, lower abdomen), and fractionation regimes (conventional, stereotactic ablative body radiation therapy - SABR) used in their clinic.

Results: The survey was completed by 78% of facilities, with 98% of respondents indicating that they used at least one form of MM.

Trends in brain cancers (glioma) in New Zealand from 1995 to 2020, with reference to mobile phone use.

Background: Some case-control studies have suggested substantial increased risks of glioma in association with mobile phone use; these risks would lead to an increase in incidence over time.

Methods: Incidence rates of glioma from 1995 to 2020 by age, sex, and site in New Zealand (NZ) recorded by the national cancer registry were assessed and trends analysed. Phone use was based on surveys.

Updated Australian diagnostic reference levels for adult CT.

Introduction: In 2018, ARPANSA published updated national DRLs for adult CT, which were first published in 2012, and augmented the national DRL categories. This paper presents the updated national DRLs and describes the process by which they were produced.

Methods: Examine patient survey data submitted to the Australian Radiation Protection and Nuclear Safety Agency (ARPANSA) National Diagnostic Reference Level Service (NDRLS).

Mobile phone use and incidence of brain tumour histological types, grading or anatomical location: a population-based ecological study.

Objective: Some studies have reported increasing trends in certain brain tumours and a possible link with mobile phone use has been suggested. We examined the incidence time trends of brain tumour in Australia for three distinct time periods to ascertain the influence of improved diagnostic technologies and increase in mobile phone use on the incidence of brain tumours.

Design: In a population-based ecological study, we examined trends of brain tumour over the periods 1982-1992, 1993-2002 and 2003-2013.

Bolus administration of intravenous lidocaine reduces pain after an elective caesarean section: Findings from a randomised, double-blind, placebo-controlled trial.

We conducted a randomised double-blind, placebo-controlled trial to assess whether a bolus dose of lidocaine during the induction of general anaesthesia would reduce postoperative pain over 24 h. Level of satisfaction with pain control at 48 h after surgery and Apgar score were also examined. A total of 100 women aged 20-35 years, who were candidates for elective caesarean section (CS) were randomised to receive either 1.

Robustness testing of an in-situ caesium extraction unit.

Following on from the successful development and validation of a prototype automated unit for the extraction of radiocaesium from seawater, the unit was redesigned to be smaller, easier to transport and better suited for field work. An extension of the validation process was undertaken to include robustness testing. Robustness testing evaluates the behaviour of a procedure when deliberate small changes are made.

Prediction of acute kidney injury within 30 days of cardiac surgery.

Objective: To predict acute kidney injury after cardiac surgery.

Methods: The study included 28,422 cardiac surgery patients who had had no preoperative renal dialysis from June 2001 to June 2009 in 18 hospitals. Logistic regression analyses were undertaken to identify the best combination of risk factors for predicting acute kidney injury.

Hospital-level associations with 30-day patient mortality after cardiac surgery: a tutorial on the application and interpretation of marginal and multilevel logistic regression.

Background: Marginal and multilevel logistic regression methods can estimate associations between hospital-level factors and patient-level 30-day mortality outcomes after cardiac surgery. However, it is not widely understood how the interpretation of hospital-level effects differs between these methods.

Methods: The Australasian Society of Cardiac and Thoracic Surgeons (ASCTS) registry provided data on 32,354 patients undergoing cardiac surgery in 18 hospitals from 2001 to 2009.

Measuring professionalism in residency training programs in Iran.

Background And Aim: To assess the Farsi (Persian) translated and modified version of the questionnaire of the American Board of Internal Medicine (ABIM) for measuring professionalism, and also, measuring the professional attitudes and behaviors associated with the medical residency training environment in Iran.

Methods: After a pilot study, a 17-item questionnaire was distributed to 282 medical residents of two major universities of Iran, from December 2006 through February 2007.

Results: Of the 282 distributed questionnaires, 259 (95.

Intravitreal Bevacizumab versus Combined Bevacizumab and Triamcinolone Acetonide for Neovascular Age-Related Macular Degeneration.

Purpose: To compare the short-term outcomes of intravitreal bevacizumab (IVB) with the combination of IVB and intravitreal triamcinolone acetonide (IVB/IVT) for treatment of neovascular age-related macular degeneration (AMD).

Methods: This randomized clinical trial was performed on 92 eyes of 90 patients with subfoveal and juxtafoveal choroidal neovascularization (CNV) secondary to AMD. The eyes were randomly assigned to receive IVB 1.
