- Background
No study has reported the association between secondhand smoke (SHS) exposure and metabolic syndrome (MetS) in self-reported never smokers verified by both self-reported questionnaire and urine cotinine.
Methods
A total of 118,609 self-reported and cotinine-verified never smokers (38,385 male; age 34.8±7.1 years) who participated in the Kangbuk Samsung Health Study between 2011 and 2016 were included. Cotinine-verified never smokers were defined as individuals with urinary cotinine <50 ng/mL. SHS exposure was defined as current exposure to passive smoking indoors at home or workplace.
Results
Prevalence of SHS exposure in the overall population was 22.6% (27.4% for males and 20.3% for females (P<0.001). The overall prevalence of MetS was 6.8% and was higher in males than in females (10.7% vs. 4.9%, P<0.001). In both genders, MetS prevalence was higher in the SHS exposure group than the non-SHS exposure group (11.3% vs. 10.4%, P=0.010 for males; 5.8% vs. 4.6%, P<0.001 for females). However, there was significant gender interaction for the association between SHS exposure and MetS (P for interaction=0.010). In the multivariate regression analyses, SHS exposure was associated with increased MetS odds only in females (odds ratio [95% confidence interval], 1.02 [0.94 to 1.11] in male vs. 1.17 [1.06 to 1.29] in female). In particular, females with SHS exposure of ≥1 hour/day and ≥3 times showed increased odds of MetS compared with those without SHS exposure (1.22 [1.02 to 1.45], 1.30 [1.14 to 1.49]).
Conclusion
This cross-sectional study showed that SHS exposure was significantly associated with prevalence of MetS in self-reported and cotinine-verified female never smokers.

Abstract

- The diagnosis of insulinoma is made primarily by the detection of an inappropriately elevated serum insulin level in the presence of a low blood glucose level. The successful resection of insulin-secreting islet cell turnors is greatly facilitated by accurate preoperative localization. But, the modalities of ultrasonography, computer tomography, magnetic resonance imaging and selective arteriography often fail to detect insulinoma smaller than 1.5 cm in diameter. In this report, we describe a patient with an insulinoma successfully localized by percutaneous transhepatic portal vein sampling but not by abdominal ultrasonography, computer tomography and selective arteriography. Percutaneous transhepatic portal vein catheterization with insulin sampling showed sudden step-up of insulin concentrations near 6 cm from distal splenic vein. During operation, a 1×1.3cm sized tumor was found at the junction of body and tail of pancreas, so distal pancreatectomy was performed, We propose that preoperative percutaneous transhepatic portal vein catheterization with measurement of radioimmunoactive insulin concentration is a safe and reliable method and plays an important role to localize insulinoma that are considered occult after conventional diagnostic studies have been negative.
