Greenhouse effect
Climate System: solar radiation from sun to earth, about half absorbed by earth’s surface and warms it, some reflected by atmosphere and earth, infrared radiation emitted from earth’s surface
Greenhouse Effect: some of the infrared radiation passes through the atmosphere but most is absorbed and re-emitted in all directions by greenhouse gas molecules and clouds (water vapor) = warms lower atmosphere and earth
Climate change - Vulnerability - Probability
Condition —- Vulnerability —- Probability
Heat exposure —- High (risk groups), moderate (general population) —- High
Extreme events —- Moderate – high (depending on region) —- High
New emerging pathogens, allergens, food safety —- Less robust Assessment possible —- Low
Classical Test Theory - psychometric properties
Objectivity – The result does not depend on the person who administers the instrument.
Validity – The instrument measures what it intends to measure.
Reliability – Readministration of an instrument leads to the same result, inter-rater (different raters) and intra rater (same rater twice) reliability
Sensitivity to change – the instrument measures the change produced by the intervention
Evidence-based medicine - Sackett definition
integration of the best research evidence with clinical expertise and patient values
Economic evaluation - Drummond definition
the comparative analysis of alternative courses of action in terms of both theirs costs and their consequences
Types of economic evaluation
Type/outcome unit
Cost-minimisation: equal effectiveness and safety of interventions
Cost-effectiveness: natural units (life years, cases detected…)
Cost-utility: QALY (longevity and quality of life)
Cost-benefit: monetary valuation of outcomes
Opportunity cost
the potential benefits which are sacrificed when resources are committed to one purpose rather than another; = the health benefit that could have been achieved had the money been spent on the next best alternative intervention
economic evaluation perspective
affects what costs are included
individual, government, health provider, society

Ecological Crisis
humans have always affected the ecosystem, but since the industrial revolution, anthropogenic effects on ecosystems increased quantitatively and qualitatively
population growth –> demand on resources
Prevalence definition
Prevalence (P) is the number of cases (having a particular disease or health trait) in a population at a given time (Pt0 = point prevalence) or in a given time period (Pt1-tn = period prevalence). It corresponds to the sum of all cases (existing and new cases) and thus indicates the existence of a disease in a population.
Magnitude of epidemic
Prevalence equation
Number of persons with the illness or trait at a certain time (t0) or in a certain period (t1-tn)/Number of persons in the population at risk at a certain time (t0) or in a certain period (t1-tn)
* 100.000
Incidence definition
The incidence (I) describes the number of cases that newly occur in a defined population over a defined period of time. This "population at risk" is, strictly speaking, the sum of the individual time sequences each individual has spent under exposure (= risk) (e.g., sum of person years, if 1 year, then = number of persons). The incidence thus measures the occurrence of new cases (persons with a specific disease). This means that at least two examinations would actually be necessary to determine the incidence: In a first step, the cases that already have the disease to be examined would have to be excluded from the study. They can not be included in either the numerator or the denominator because only persons who can get the disease (population at risk) can appear there. Then it would be necessary to determine in an observation period how many really new cases occur. Only new cases belonging to the observed population may be counted. For large populations, the incidence cases are not removed from the population under observation (denominator), as the distortion of calculated rate by them is in the decimal range and is irrelevant.
Danger of epidemic
Incidence equation
Number of persons who become ill during the observation period/Sum of the length of stay of each individual person in population at risk
* 100.000
Mortality
Number of deceased/Number of population
* 1.000 or 10.000 or 100.000
Perinatal mortality
number of still-born, and those who died at birth and during the first week of life, relative to the number of live births in the same calendar year.
Infant mortality
Deceased in the first year of life, relative to the number of live births in the same calendar year.
Case Fatality (Lethality)
Number of persons with a certain disease who died during the observation period/Number of Persons who suffered from this disease within this time
* 100
(usually expressed as percentage)
relative number
E.g.: In Austria (2006) in total there are 3,360,072 men over the age of 15 years. Of these, 1,848,040 men are overweight or obese according to Statistics Austria’s health survey. With these numbers (1,848,040 out of 3,360,072), the order of magnitude are not readily apparent.
This becomes much easier when calculating relative numbers: The numbers above correspond to a total of 55% of the male population over 15 years. At the same time, it also equals 550 per thousand (550 per 1000), or 5500 / 10,000, or 55,000 / 100,000 and 550,000 / 1,000,000 men. One could say so well that of one million men in Austria, 550,000 are overweight or obese.
rate
E.g.: In Austria in 2004 (= 1 year of observation) a total of 17,343 women were newly affected by cancer. This corresponds to a “new disease rate” (incidence) of 17,343 / 4,205,543 female-years = 412.4 / 100,000 female-years. This means that in 2004, of 100,000 (theoretically observed) women (= 100,000 person years), 412.4 had cancer.
Dietetic factors with convincing blood pressure lowering effects
body weight (+ visceral fat) - adverse - ++
salt (sodium chloride) - adverse - ++
60% salt-sensitive HT
potassium - protective - ++
supplementation problematic (overdose/GI issues), increase intake through food
alcohol - adverse - ++
sympathetic NS activation
DASH (dietary approaches to stop HT) diet - protective - ++
European guidelines on cardiovascular disease prevention in clinical practice
Characteristic of a healthy diet
➢Saturated fatty acids to account for <10% of total energy intake, through replacement by polyunsatureated fatty acids
➢ Trans-unsaturated fatty acids: as a possible, preferably no intake from processed food, and <1% of total energy intake from natural origin.
➢ <5g of salt per day
➢ 30-45g of fibre per day, from wholegrain products, fruits and vegetables
➢ 200g of fruit per day (2-3 servings)
➢ 200 g vegetabled per day (2-3 servings)
➢ Fish at least twice a week, one of which tob e oily fisch (omega 3, Vit. D)
➢ Consumption of alcoholic beverages should be limited to two glasses per day (20g/day of alcohol) for men and one glass per day (10g/day of alcohol) fo women.
Nurse Model
Naming: naming emotions Understanding: showing understanding Respecting: show respect for your opposite`s feelings and emotions Supporting: offer support Exploring: explore the background
medical pluralism
multiple medical systems/healing traditions coexist
typically biomedicine dominant
hybridization
people see multiple types of care at the same time, such as TCM and biomedicine
often in places with resource shortages
idioms of distress
varieties of ways that people express their distress in a clinical setting
culturally-constructed but within a culture there is a wide range
bioculturalism
interaction between biology and culture in health and illness
pain is biological, but the expression and experience is cultural
culture/behaviour impacts infectious disease spread
biopower
form of social control within context of modern nation states
modern regimes of knowledge/practice –> control through dissemination of knowledge in institutionalized form
control turns into behaviour (choices are not independent - socially constructed)
M. Foucault
It relates to the practice of modern nation states and their regulation of their subjects through “an explosion of numerous and diverse techniques for achieving the subjugations of bodies and the control of populations”
syndemics
= synergistic epidemic
critique of treating diseases as isolated, distinct entitites, independent of social context
example: HIV and TB
the aggregation of two or more concurrent or sequential epidemics or disease clusters in a population with biological interactions, which exacerbate the prognosis and burden of disease.
structural violence
“suffering structured by historically given, economically driven, processes and forces that constrain agency” P Farmer
health systems reinforce political economic regimes of oppression
a form of violence wherein some social structure or social institution may harm people by preventing them from meeting their basic needs (such as institutionalized racism)
“the increased rates of death and disability suffered by those who occupy the bottom rungs of society, as contrasted with the relatively lower death rates experienced by those who are above them”
intersectionality
different aspects of social location are related
various forms of social stratification, such as class, race, sexual orientation, age, religion, creed, disability and gender, do not exist separately from each other but are woven together.
structural competency
ability of health care providers and trainees to appreciate how symptoms, clinical problems, diseases and attitudes toward patients, populations and health systems are influenced by ‘upstream’ social determinants of health.

Odds Ratio definition
The odds ratio is defined as the ratio of the odds of A in the presence of B and the odds of A in the absence of B, or equivalently (due to symmetry), the ratio of the odds of B in the presence of A and the odds of B in the absence of A. Two events are independent if and only if the OR equals 1
= RR if disease is rare
OR equation
AD/BC = (A/C)/(B/D)
EECN/CEEN
(EE/EN)/(CE/CN)
