Q

When we are stressed, we release glucocorticoids, where did these come from?

A

ACTH is released by pituitary gland which results in production of glucocorticoids

Q

Q

(blank) produced at nerve endings can module immune-cell function by binding its receptor at the surface of cells within lymphoid organs. How is this bidirectional?

A

noradrenaline

because cytokines produced immune cells can modulate the activity of the hypothalamus.

Q

What could the correlations between stress and immunity be linked to?

25
Q

What is the possible mechanism for slow healing under stress?

A

reduced production of IL-1

26
Q

(blank) adversely affect immune and endocrine function.

A

pain

27
Q

What did research show about painful stimuli given to animals and the immune system?

A

painful stimuli suppressed NK cell activity, lymphocyte proliferation to mitogens, specific antibody production, and mixed lymphocyte reaction AND elevated beta-endorphin and corticosterone level

28
Q

What are surgeries affects on immunity? How do you fix this?

A

supresses it

anesthesia can block this pain and thus reduce this problem

29
Q

What are some key behavioral risk factors for surgery?

A

smoking, alcohol, drug abuse, and nutrition

30
Q

Distressed patients are more likely to have (blank) and (blank) disturbances.

A

sleep and appetite

31
Q

Deep sleep is associated with release of (blank) a hormone that is associated with wound healing

A

GH

32
Q

Partial sleep loss on night can result in elevated (blank) levels the next evening

A

cortisol

33
Q

T or F
postoperative sleep is often disturbed by the physiological stress of surgery, pain, opoid use, and the hospital enviromen

A

T

34
Q

What 2 things are predictative of poorer outcomes after surgery?
How do you deal with this?

A

fear or stress

greater pain, longer hospital stays, more postoperative complications, and poorer treatment adherence

35
Q

How do you increase speed of recovery after surgery?

A

give anesthesia
give info
relaxation training

36
Q

T or F
Elderly women with depression have an increased risk of mortality similar to that conferred by other cardiovascular risk factors like HTN, smoking, hyperlipidemia, obesity and diabetes

A

T

37
Q

(blank) symptoms are linked with coronary heart disease.

A

depressive (4.5 X greater risk)

38
Q

Chronic depressed mood has been found to be linked to (blank) risk

A

cancer

not conclusive

39
Q 
(blank) is linked to risk for:
osteoporosis (lower bone mineral density)
decline in muscle strength
reduced rehab effectiveness
reduced diabetic management
increased morbidity
increased mortality
A

Depression

40
Q

(blank) can provoke increases in HR and BP, enhance secretion of stress-related hormones and dysregulates a range of immunological activities

A

pain

41
Q

(blank) plays a role in the development of CHD and contributes to poorer prognosis after acute coronary events, including death and recurrent ischemic events

A

Anxiety (3 X increase risk)

42
Q

(blank) symptoms were associated with significantly increased risk of MI and CHD-related death over a 20-year period in women who were homemakers

A

Anxiety

43
Q

How does chronic anger and hostility impact health?

A

negatively

2X increased risk of CV mortality

44
Q

A large prospective study of employees found that hostility predicted the total number of long-term medically certified absences over a 4 year period for women or men?

A

men only

45
Q

Do relaxation techniques and hypnosis help with immunity?

A

yes they do, in fact in a study with medical student, hypnosis and relaxation increased T lymphocytes

46
Q

What did teaching relaxation to older adults show?

A

significant increases in NK cell activity and decreases in HSV antibody titers (consistent with improved immune function)

47
Q

T or F
Subjects with Stage I or II malignant melanoma in a 6-week structured group intervention that included stress management showed reduced psychological distress and significant immunological change

A

T

48
Q

T or F
Undergraduates randomly assigned to a group where they wrote about traumatic/troubling events demonstrated a higher mitogen response following baseline, and had fewer visits to the student health center compared to controls

A

T

49
Q

A study teaching stress management to a group of HIV-seropositive men showed changes in a battery of immunological measures.
T or F

A

F

the study showed that HIV-seropositive men did not show changes in a battery of immunological measures

50
Q

Is social isolation good for immunity?

A

nope (isolation is comparable to those of smoking, blood pressure, blood lipids, obesity and physical activity)

51
Q

T or F

marital quality has been associated with immune and endocrine function

A

T

52
Q

What did the ACE (adverse childhood experiences) studies show?

A

showed that abuse (emotional, physical sexual) and household dysfunction (domestic violence, parental mental illness, parental substance abuse, parental crime, marital discord/divorce) was associated with health outcomes in mid-life

53
Q

T or F

adverse childhood experiences are “vastly more common than recognized or acknowledged”

A

T

54
Q

How many subjects of the ACE studies had 1 or more ACEs
2 or more?
4 or more?

A

half of subjects
1/4
1/16

55
Q

Exposure to one category of ACE gives you an (blank) % likelihood of exposure to another category. Are these commonly assess by MDs?

A

80

no

56
Q

T or F

Adverse childhood experiences “have a powerful relation to adult health a half-century later”

A

T

57
Q

If you have 4 or more aces what are you susceptible for?

A

2.2 fold increased risk of ischemic heart disease

58
Q

If you have 7 or more aces what are you susceptible for?

A

3.6 fold increased risk of IHD after adjustment for CAD risk factors

59
Q

Relationship between childhood trauma and IHD is more strongly mediated by (blank) than by traditional cardiac risk factors

A

psychological factors (depression, anger)

60
Q

Adverse childhood events increases risk for other problems…. such as???

A

obesity, somatic, smoking, injected drugs

61
Q

T or F
much of what causes time to be lost from work is actually predetermined decades earlier by the adverse experiences of childhood

A
