Background: The study examined the prevalence of suicidal ideation and suicide attempts among registrants of public community healthcare centers and compared between the characteristics of mental and general healthcare center (GHC) registrants. Methods: The study measured lifetime suicidal behaviors, psychosocial variables, psychiatric comorbidities, and suicide related factors. Results: A total of 132 (73.7%) and 126 (42.3%) mental and GHC registrants, respectively, reported a history of suicidal ideation; whereas 64 (35.8%) and 29 (9.7%) of mental and GHC registrants, respectively, reported a history of suicidal attempts. Scores of the Beck Depression Inventory (BDI) for both suicidal ideation groups were above the severe level, although only 2% of GHC group recognized their diagnoses of depressive disorders. Conclusion The study observed high suicidal risk among the mental and GHC registrants. High BDI scores and unevaluated depression under score the need for screening and provision of appropriate early interventions in public community healthcare centers.

Cigarette smoke is a major risk factor for several diseases, including chronic obstructive pulmonary and cardiovascular diseases. The toxicity of the cigarette smoke can be determined in vitro. The cytotoxicity test of the cigarette smoke is commonly conducted using the cigarette smoke condensate (CSC) and cigarette smoke extract (CSE). The CSC and CSE methods are well known for sampling of the particles and water-soluble compounds in the cigarette smoke, respectively. In this study, the CSC and CSE were analyzed by using a gas chromatography-mass spectrometry (GC-MS) system equipped with a wax column for separation of the volatile organic compounds. The cytotoxic effect of the CSC and CSE were evaluated thoroughly by comparing the analytical results of the CSC and CSE samples. The total concentration of the volatile organic compounds detected in the CSC sample was similar to that in the CSE sample based on the peak area. Except for the dimethyl sulfoxide solvent, nicotine had the highest concentration in the CSC sample, while acetonitrile had the highest concentration in the CSE sample. The compositions were as follows: (1) CSC sample: 55.8% nicotine, 18.0% nicotyrine, 3.20% 1,2,3-propanetriol, triacetate, 1.28% ethyl chloride, 1.22% phenol, etc. and (2) CSE sample: 18.7% acetonitrile, 18.0% acetone, 12.5% 2-hydroxy-2-methyl-propanenitrile, 8.98% nicotine, 5.86% nicotyrine, etc. In this manner, to accurately examine the cytotoxicity of the cigarette smoke using CSC or CSE, the components and their concentrations in the CSC and CSE samples should be considered.
