15 Simple Description

16 Sample - NHI enrollment database - Inclusion: age, sex… - Exclusion: foreigners…Definition - Schizophrenia: inclusion, exclusion - Prevalence: definition of “prevalent cases”? - Incidence: definition of “new cases”? Methods

17 Simple Description Associations IF 4.458, Ranking 18 / 117 (Psychiatry)

18 Simple Description Sample - Case: 59,257 schizophrenia patients - Control: 178,156 age- and gender-matched individuals without schizophrenia Follow-up period Follow-up period : 9 years ( ) Outcome measure - cancer incidence and survival time after cancer diagnosis Methods

19 Cancer incidence patients with schizophrenia: 1145 (1.93%) control group: 5294 (2.97%) for all types of cancer except breast and cervical/uterine cancer Male: OR=0.50 (95% CI, 0.46–0.55); Female: OR=0.81 (95% CI, 0.74–0.88) adjusted hazard ratio 0.71 (95% CI, 0.66–0.76) Results Simple Description

20 Association / Relationship IF 4.224, Ranking 3 / 26 (Anesthesiology )

29 Simple Description Birth Seasonality in Schizophrenia: effect of latitude, gender, and income Chin Cheng, Ching-Heng Lin, El-Wui Loh, Tsuo-Hung Lan Taichung Veterans General Hospital, Taiwan Under Review

30 Methods Study Sample - Case: 5,047 schizophrenia patients - Control: 631,911 general population - Data retrieved for Data for year of birth ranged from 1950 to 1989 (age20-59) - Data obtained from the inpatient, outpatient, and ambulatory claims database. Measurement - Birth seasonality in schizophrenia, considering influences of gender, and income status

31 1. A significant winter/spring birth excess in schizophrenia in Taiwan, a low latitude area 2. A gender difference with female predominance 3. More pronounced in low income status Results

32 Association / Relationship The Correlation of Antidepressants use and Mortality of End-Stage Renal Disease Chia-Jui Tsai, Ching-Heng Lin, El-Wui Loh, Tsuo-Hung Lan Taichung Veterans General Hospital, Taiwan IF 1.25, Ranking / (Nephrology)

34 Methods Definition Antidepressants exposure - All kinds of antidepressants prescriptions - At least two consecutive months (outpatients) or inpatients one year before receiving their diagnosis of ESRD or after the diagnosis New onset ESRD New onset ESRD during the year , > 30 y/o Exclusion Exclusion : depression diagnosed before new onset ESRD Endpoint Endpoint : Occurrence of death, or end of study

35 Confounding Factors Well known risk of mortality : * CVD * DM * Hypertension * Hyperlipidemia

36 Survival Curves

37 Association / Relationship The Association of SSRI Use and Stoke in Geriatric Population Chia-Chun Hung, Ching-Heng Lin, El-Wui Loh, Chin-Hong Chan, Tsuo-Hung Lan Taichung Veterans General Hospital, Taiwan Under Review

38 Methods Definition of stroke The stroke diagnosis was identified by meeting the occurrence of ICD-9, codes from 430 to 438 (cerebro- vascular disease) in any inpatient treatment or outpatient treatments during the 9-years period. Patients who had accompanied diagnosis of head injury (ICD-9 code: , ) and stroke within two weeks of head injury events were excluded. The endpoint of follow-up was occurrence of first stroke event, death, or end of study on December 31, 2009.

39 METHODS Definition of co-morbidities Co-morbidities for stroke, including myocardial infarction (MI), angina pectoris (AP), atrial fibrillation (AF), peripheral arterial occlusive disease (PAOD), congestive heart failure (CHF), diabetes mellitus (DM), hypertension, hyperlipidemia, and renal diseases in the last 12 months before first SSRI prescription were included in analysis. MI (ICD-9 code: ), AP (ICD-9 code: 413), AF (ICD-9 code: 427), PAOD (ICD-9 code: 444), CHF (ICD-9 code: 428), DM (ICD-9 code: 250), hypertension (ICD-9 code: 401 to 405) and hyperlipidemia (ICD-9 code: 272) were confirmed by the records of one or more prescriptions for the diagnoses, while renal diseases were confirmed when ICD-9 code or 585 appeared in the NHI records.
