pollutants - particulate matter?
* A mix of solid and liquid droplets arising mainly from fuel combustion and traffic * This has the greatest impact on peoples’ health
181
pollutants - NO2?
* Arising mainly from road traffic and indoor gas cooking
182
Pollutants - sulphur dioxide?
* Arises mainly from burning fossil fuels * Associated with asthma and poor lung function
183
pollutants - ozone?
* Caused by the reaction of sunlight with pollutants from vehicle emissions * A major factor associated with asthma
184
most toxic PM?
* particulates are a mix of solid and liquid droplets in the air e.g. soot * PM 2.5 are the most toxic and are associated with CR disease and lung cancer
185
indoor air pollution?
* Worldwide smoke fires used for cooking. * Biomass fuels produce large amounts of particulate matter * contributes to COPD and childhood respiratory infection
186
occupational asthma?
* commonest cause of occupational lung disease in the UK * interactionw smoking and atopy
187
Work related asthma?
188
occupational asthma causes
189
identifying occupational asthma?
* ask abt occupation - are symptoms worse at work and are they better when they're away from work - weekends/ holiday? * peak flow diary * challenge tests
190
pneumoconiosis?
* lung disease resulting from inhalation of dusts - Long latency between exposure and development of disease
191
types of pneumoconiosis?
* Coal workers pneumoconiosis * Silicosis * Asbestosis * Many other rarer causes (eg. Berylliosos, Bagossis etc).
192
silicosis?
* rare * looks like sarcoidosis * predisposes to TB and LC * Upper lobe nodules and lymph node calcification
193
asbestos can cause a range of diseases?
* Benign asbestos related pleural plaques * Asbestos related pleural effusions * Diffuse pleural thickening * Mesothelioma * Lung fibrosis (asbestosis) * Lung cancer
194
Mesothelioma?
* almost always caused by occupational exposure * long latency * rising prev in UK despite being banned in the 70s * incurable
195
occupational lung cancer?
* Estimated to cause 10% of lung cancers in men * Asbestos estimated to cause 60% of these but unclear whether has to cause fibrosis (asbestosis) first or direct effect
196
other causes of occupational lung cancer?
* Also arsenic,chromium, coal gas, coke production, cadmium, chloromethyl ethers, silica, radon, soot
197
# Role the health and safety executive?
* independent regulator that aims to prevent work related death, injury and ill-health * produce guidance
198
organisations with responsibility for the environment and health?
* Deparment for environment, food and rural affairs * PHE - air pollution
199
occupational lung diseases?
200
Jobs at risk of sillicosis?
- mining - slate works - foundries - potteries
201
high incidence TB countries?
- india - indonesia - pakistan - china
202
RF for TB?
- Place of birth - HIV - Prison inmates/staff, - nursing homes - homeless shelters, - health care workers, - substance abuse, - immigrant centres & migrant workers camps
203
medical factors inc TB risk?
- under nutrition - smoking - cancer - HIV - taking illicit drugs - alcoholism
204
social factors increasing risk of TB?
Single/widowed men, immigration, incarceration, homelessness
205
contact tracing in TB?
* idenficiation of contacts of TB positive individuals * national target is for 90% of people with infectious TB to have at least 5 contacts traced * pre-entry screening programme for testing of active pulmonary TB in migrants from high incidence countries who apply for visas which reduces importation of active TB
206
# Benefit over mantoux INF-gamma tests?
* quantiferon TB gold - used in place of TB testing for previous infection * not confounded by prior BCG vaccine * main role is screening for latent disease
207
what does the INF-G test measure?
* measures cell mediated immune response by looking at INF-g released by T cells in response to TB antigens
208
TB drugs?
*Isoniazid *Rifampin *Pyrazinamide *Ethambutol RIPE
209
other tests for TB patients?
* Testing for HIV * hep B and C serologic tests if risks present
210
tests to do when TB Tx is initiated?
* AST * ALT * bilirubin * ALP * serum creatinine * platelet count * Visual acuity and color vision tests (when EMB used)
211
Approaches to controlling spread of TB ?
* improve vaccination uptake * address TB in under-served populations * improve access to services and ensure early diagnosis * quarentine * DOT - directly observed treatment when non-compliance suspected e.g. homeless, alcoholics
212
MDT TB teams should provide data to TB control boards on:
screening uptake, referrals and the number of active TB cases identified.
213
TB control boards should?
* control boards should develop TB prevention and control programmes working with commissioners, Public Health England and NHS England * **TB control boards should be responsible for developing a TB prevention and control programme** based on the national strategy and evidence‑based models.
214
roles of the TB control boards?
* TB control boards should plan, oversee, support and monitor local TB control, including clinical and public health services and workforce planning.
215
CF screening?
heel prick blood test
216
advanced care plainning?
- process of discussion between and indiv and their care providers - facilitates and enables individuals to think abt the care that they would like to receive - allows them to choose where they want to die
217
Benefits of ACP?
* patient centered * prevents over-treatment when the patient lacks capacity
218
Indicator of deterioration?
SPICT tool - indicators of deteriation for each disease
219
EoL care plan:
ensures best quality of care during the patients last days
220
advanced care planning leads to
221
most common cause of liver failure in the UK?
Paracetamol overdose
222
when is prev higher than indicence?
In chronic disease prevalence is greater than incidence - in acute disease the incidence is greater than the prevalence
