Q

What is Asthma?

A

a long-term lung condition where the airways are sensitive and thus inflame when exposed to triggers( tobacco smoke, pollution, chemicals, house dust mites, pets …)

20
Q

Symptoms of Asthma include…

A

shortness of breath, tightness of chest, cough, difficulty breathing

21
Q

T/F

1 in 8 Australians have asthma

A

False, 1 in 10 have asthma

22
Q

What population group is asthma more common in?

A

the prevalence of asthma is higher in women aged above 55 years

23
Q

People who are at an increased risk of asthma attacks during thunderstorm asthma events are..

A

people with….

  • no history of ashtma
  • had childhood asthma
  • asthmatics
24
Q

Risk factors for thunderstorm asthma include…

A

Asthmatics, Hay fever sufferers and the Rye grasspollen trifecta

25
Q

How to prevent thunderstorm asthma attacks?

A

Manage asthma and hay fever, carry reliever medication, monitor pollen forecast, and weather, masks, education

26
Q

Public health response to Thunderstorm asthma and how will these be measured as sucessful

A
  1. Coroner investigation into the 10 deaths
  2. State government investment of >$15 million to predicting and responding to these events
    • pollen monitoring systems and forecasting systems
  3. Public health campaigns
  4. clinical guidelines to manage risk
  5. revised state health emergency response plan
  6. process for warnings on VicEmergency website and app.

How successful these are will only be known in another mass Thunderstorm asthma event.

27
Q

What is the Hazelwood Health Study?

A

It is an ongoing and long-term study looking at the resident of Hazelwood who was exposed to smoke from the Hazelwood fire and coal mine fire for 45days. The research questions explored the effect of heavy smoke on…

  • dev of heart and lung conditions
  • pregnancy and infancy
  • psychological distress
  • development of cancer
28
Q

Key findings of the Hazelwood Study?

A
  • decreased lung function
  • increased chest tightness and chronic cough
  • increased COPD in nonsmokers.
29
Q

Adults with Asthma when comparing Morewell residents and Sale residents ….

A

No difference was found in asthma symptoms, the severity of lung function/airway inflamm but it was found that Morewell residents were on medium to high doses of preventers as compared to unexposed population

30
Q

Residents who were pregnant at the time of the Hazelwood fire report…

A

More incidence of cough, runny nose, wheeze, and URT infection. Unsure if this is a bias as we have an awareness of the exposure

31
Q

Results of the Hazelwood study have potential confounding factors which are…

A

Social determinants of health ( Income, Access to health services, adherence to medication/health literacy, exposure to other sources of smoke/open fire heating systems)

32
Q

Modified Monash Model of Rurality and Remoteness and Morewell

A

doesn’t only look at a distance but also looks at factors that can affect recruiting and maintaining a health workforce like education and school availability. Morwell( where the Hazelwood fires were) are closed 3 which means they have lower access to health services which could be affecting their recorded outcomes as seen in the Hazelwood study.

33
Q

Health effects of Bushfire smoke

A

Asthma, COPD, other resp infections both during and after.

Also may increase CV morbidity, psychological disorders, adverse birth outcomes and eye irritation

34
Q

Social determinants of health effects of bushfire smoke

A

homelessness, poverty, social disruption/social isolation –> mental health

35
Q

Health of Firefighters

A
  • surprisingly lower mortality thought to be the string healthy worker effect and lower rates of smoking
  • no evidence of an increase in CV and resp mortality
  • statistically significant increase in prostate cancer and melanoma
36
Q

What is Silicosis?

A

An occupational lung disease that damages the lung air sacs, causes scarring and fibrosis.

It causes breathing difficulties, cough, weight loss, and tiredness.

It increases the risk of other respiratory problems

37
Q

Engineered stone silica content in comparison to marble and effect

A

95% to 4% meaning more crystalline silica/silica dust gets lodged in the lungs and causes disease

38
Q

3 forms of silicosis

A
  1. Acute Silicosis
  2. Accelerated Silicosis
  3. Chronic Silicosis
39
Q

Define

Acute Silicosis

A
  • develops after short exposure ,few weeks to years , of very high levels of silica dust
  • causes severe inflammation and as outpouring of protein into the lungs
40
Q

Define

Accelerated Silicosis

A

it develops after exposure of 3-10 yrs to moderate-high levels of silica dust.

Causes inflamm, protein in the lungs and scarring of the lungs/fibrotic nodules

Lung function deteriorated 10x faster than age-related deterioration

41
Q

Chronic Silicosis

A

It develops after long-term exposure to lower levels of silica dust.

10+ yrs of exposure.

it is the “classic” silicosis

42
Q

Does Silicosis have a cure?

A

No, but it can be prevented

43
Q

Silicosis prevention methods

A

Wet cutting, proper ventilation, washing hands and clothes, PPE

44
Q

Cutting the stone dry for 30 minutes ….

A

exposes a worker to 400x the 8-hour exposure limit

45
Q

What is the rough Australian/ Queensland prevalence of silicosis amongst stone workers?

A

~12%( 98/800)

46
Q

It is estimated ….. will develop silicosis

A

5,700 poeple

47
Q

T/F

In December 2019 the estimate of cases was 500 nation wide

A

No, it was 350

48
Q

It is estimated …..% of workers exposed pre-2018 are diagnosed with silicosis

A

25%

49
Q

National Dust Sisease Taskforce recommendations

A
