1.Social Network Effects on Post-Traumatic Stress Disorder (PTSD) in Female North Korean Immigrants.
Journal of Preventive Medicine and Public Health 2011;44(5):191-200
OBJECTIVES: The goal of this paper is to examine the social network effects on post-traumatic sdress disorder (PTSD) in female North Korean immigrants who entered South Korea in 2007. Specifically, it attempts to verify if the density and composition of networks make a difference after controlling for the network size. METHODS: A multivariate logistic regression is used to probe the effects of social networks using the North Korean Immigrant Panel data set. Because the data set had only completed its initial survey when this paper was written, the analysis was cross-sectional. RESULTS: The size of the support networks was systematically related to PTSD. Female North Korean immigrants with more supporting ties were less likely to develop PTSD, even after controlling for other risk factors (odds-ratio for one more tie was 0.8). However, once we control for the size of the network, neither the density nor the composition of the networks remains statistically significant. CONCLUSIONS: The prevalence of the PTSD among female North Korean immigrants is alarmingly high, and regardless of the characteristics of supporting network members, the size of the supporting networks provides substantial protection. This implies that a simple strategy that focuses on increasing the number of supporting ties will be effective among North Korean immigrants who entered South Korea in recent years.

BACKGROUND/AIMS: Bronchiectasis is aggravated by gastroesophageal reflux disease (GERD) owing to micro aspiration. Some researchers note the effect of antireflux surgery in bronchiectasis with GERD. However, few have investigated the effects of medical antireflux therapy. We investigated the effect of proton pump inhibitors (PPIs) in bronchiectasis with GERD. METHODS: From March 2003 to May 2015, the clinical records of patients who had bronchiectasis with GERD were reviewed. Patients underwent an initial pulmonary function test (PFT) and chest computed tomography when diagnosed with bronchiectasis. One group with typical GERD symptoms was treated with PPIs, while the other group was not. Both groups underwent PFTs within six months after completing PPI therapy. Population characteristics and associations were compared between the groups. RESULTS: Two hundred and fifty-seven patients (124 male, 133 female; mean age 67.6±10.0 years) were included. There were no significant differences between the groups in terms of forced vital capacity (FVC; p=0.239), forced expiratory volume in one second (FEV1; p=0.555), or FEV1/FVC (p=0.374) after PPI therapy. However, there were significant improvements in FVC (p=0.002) and FEV1 (p=0.006) in patients with high BMI in the PPI treatment group. CONCLUSIONS: PPIs have no effect on the pulmonary function in patients with bronchiectasis and GERD. However, PPIs were noted to produce improvements in lung function in patients with bronchiectasis and high BMI.

BACKGROUND/AIMS: Eosinophilic esophagitis (EoE) is a chronic, immune/antigen-mediated esophageal disease, with eosinophilic infiltration limited to the esophagus. A minority of EoE patients respond well to proton pump inhibitor (PPI) therapy alone, and that condition is labelled PPI-responsive esophageal eosinophilia (PPI-REE). The prevalence of PPI-REE among EoE cases is unknown. We aimed to identify clinical manifestations of PPI-REE, and the proportion of PPI-REE among all EoE cases. METHODS: We reviewed pathology of the 4,075 patients who underwent esophageal biopsy at an institution from March 2003 to July 2015. EoE was diagnosed based on esophageal symptoms and eosinophilic infiltration limited to the esophagus, with ≥15 eosinophils per high-power field. We collected endoscopic and pathologic findings, and clinical features for these patients. RESULTS: Thirteen (0.3%) patients were diagnosed with EoE. Clinical manifestations were dysphagia (30.8%), foreign body sensation (23.1%), regurgitation (23.1%), cough (15.4%), heartburn (15.4%), nausea (7.7%), dyspepsia (7.7%). The endoscopic findings noted were polypoid lesion (23.1%), whitish plaque or exudate (23.1%), linear furrow (7.7%), concentric ring (7.7%), nodularity (7.7%), erosion (7.7%), and normal (30.8%). Of these patients, five had a favorable course with PPI as monotherapy. CONCLUSIONS: The proportion of EoE among all patients undergoing endoscopic biopsy was 0.3%. Of those, PPI-REE comprised 38%. Most of the endoscopic findings were atypical or normal when compared to the typical findings in EoE. In conclusion, patients who present with symptoms related to esophageal dysfunction need esophageal biopsy, regardless of the endoscopic findings. Moreover, patients diagnosed with EoE need to be treated first with PPI alone.
