Q

Dx: anti-anxiety agents

A

3大类：

  1. BZ: benzodiazepine 苯(并)二氮卓， chlordiazepoxide

fast acting, but high risk for dependence/addition, likely to be abused - only used for a limited time for acute sym, 比如戒酒病人在刚刚开始戒酒的初期阶段

  1. buspirone (BuSpar): 丁螺环酮
    与苯(并)二氮卓正相反：low abuse potential, but slow action (take 2 weeks to become effective): long term maintain for GAD, but little immediate effect
  2. b-blocker: control ANS sym (tachycardia)

delayed orgasm - caused by ↑ 5-HT

not secondary ED :

fluoxetine and other selective serotonin reuptake inhibitors (SSRIs) are more likely to cause delayed or absent orgasm (orgasmic disorder). That is why the SSRIs are useful in managing premature ejaculation.

Brief psychotic disorder, schizophreniform disorder, vs. schizophrenia?

A

时间长短从短到长：

62
Q

measures calculated for cohort study?

for case-control study?

A

cohort study: people are followed over time for developing a disease (从受试开始看）：

measures: absolute, relative (incidence fold change), attributive (incidence做减法） risks

Case-control study: people with or without the disease are asked about PREVIOUS exposure to the variable

measure: odds ratio

63
Q

calculate ARP (attributable risk percent)?

= (risk in exposed - risk in unexposed)/risk in exposed = (RR-1)/RR

64
Q

which will be influenced by prevalence:

sensitivity, specificity, positive/negative predictive value?

reliability = reproducibility

measure by “CV” (coefficient of variation） = S.D./mean

68
Q

how to calculate # needed to treat (NNT)? and number needed to harm (NNH)?

A

NNT = 1/ARR (absolutely risk reduction) = 1/ (sick/total placebo - sick/total treated)

NNH = 1/ attributable risk = 1/ (sick/total treated - sick/total placebo)

69
Q

what is “power of a study”?

A

power = 1 - beta (beta: type II error, i.e.: stating there is no difference when one truly exists); this is the probability of rejecting the null hypothesis when it is truly false

70
Q

calculate 95% CI? 99% CI?

A

95% CI = mean ⍏ 1.96 * SD/ √n

SEM (standard error of the mean) = SD/ √n

99% CI = mean ⍏ 2.58 * SD/ √n

71
