Objective: To pilot surveillance to describe environmental, personal and behavioural risk factors for people presenting to hospital emergency departments (EDs) with heat illness.
Methods: We conducted a retrospective case series and telephone interview study of people presenting to EDs across South Western Sydney, Western Sydney and Nepean Blue Mountains Local Health Districts with heat illness over the 2017/18 and 2018/19 summer periods (1 December to 28 February). We used the Public Health Rapid Emergency Disease Syndromic Surveillance (PHREDSS) 'heat problems' syndrome to identify people with heat illness and medical records to find contact details.
Background: Syphilis is a nationally notifiable sexually transmitted infection (STI). Rates of syphilis notifications have been on the increase in Australia. Given these increases, we wanted to study the epidemiological trends of syphilis notifications in the Nepean Blue Mountain Local Health District (NBMLHD) over a ten-year period across different healthcare settings.

- Current models of floral nectar production overlook the role of photosynthesis in green nectaries, such as those found in Mānuka flowers, which produce nectar containing sugars and dihydroxyacetone (DHA).
- The study examined how light, flower age, temperature, and inhibitors like DCMU and pyridoxal phosphate affect nectar production and composition.
- Findings showed that photosynthesis in green nectaries enhances nectar sugar production and alters the ratio of DHA to other sugars, indicating that light exposure and photosynthetic activity are crucial for nectar quality.
Geographic information systems (GIS) have emerged in the past few decades as a technology capable of assisting in the control of infectious disease outbreaks. A Legionnaires' disease cluster investigation in May 2016 in Sydney, New South Wales (NSW), Australia, demonstrated the importance of using GIS to identify at-risk water sources in real-time for field investigation to help control any immediate environmental health risk, as well as the need for more staff trained in the use of this technology. Sydney Local Health District Public Health Unit (PHU) subsequently ran an exercise (based on this investigation) with 11 staff members from 4 PHUs across Sydney to further test staff capability to use GIS across NSW.

- Notification rates for chlamydia and gonorrhoea have risen in New South Wales, indicating a need for focused public health interventions in smaller regions.
- Analysis of data from Western Sydney revealed that males are significantly more at risk for gonorrhoea, and younger individuals (15-29 years) are particularly vulnerable to both infections.
- The study suggests that targeted health promotions and clinical services are needed for at-risk demographics, although limitations include uncertainties about testing patterns.
