Food addiction refers to a condition in which individuals exhibit addictive-like behaviors toward food, like those observed in substance abuse. Although still debated, evidence supporting the validity and usefulness of the concept of food addiction is growing.Food addiction is particularly associated with obesity and eating disorders involving binge eating. This study discusses the cases of two adolescent patients who presented with anorexia nervosa. During the recovery phase of anorexia nervosa, binge eating was observed, and the patterns of binge eating significantly differed between patients, with and without food addiction. Therefore, healthcare professionals treating eating disorders should be aware of food addiction and modify their treatment strategies accordingly.

OBJECTIVE: This study was carried out to obtain basic data required to plan and develop consumer-centered internet health information site for Korean population. METHODS: An internet survey was conducted on 5 internet patient community sites between 23 January and 5 February, 2007. A total of 958 surveys were completed and included in the study. Data were analyzed with descriptive analysis, Pearson's correlation analysis, and stepwise logistic regression analysis using SPSS version 12.0. RESULTS: According to our logistic regression analysis, the more internet usage, foreign country residents, members of breast cancer internet community, any workers except sales, and higher level of necessity/usefulness/reliability showed a higher Odds ratio for frequency of internet health information usage. Educational status, frequency of using internet, importance, necessity, usefulness, reliability of internet health information (p<.001), income, and satisfaction of internet health information (p<.05) were statistically significant in the frequency of internet health information usage. CONCLUSION: Above characteristics should be considered for planning to develop consumer-centered internet health information portals.

BACKGROUND: Nuclear enzyme poly (ADP-ribose) polymerase (PARP) activated by DNA damage participates in DNA repair. However, overactivation of PARP could be an important pathogenic mechanism of ischemic cell death. We investigated the protective effect of an inhibitor of PARP, 3-aminobenzamide (3-AB), against ischemia/reperfusion injury in ischemic stroke model. METHODS: Occlusion of left middle cerebral artery (MCA) was done by intraluminal filament technique in 24 rats weighing from 315 g to 358 g, and reperfusion was done at 2 hours after occlusion. To evaluate the effect of PARP inhibitor in ischemic stroke, 3-AB was administered to 12 rats (3-AB group) 10 minutes before artificial occlusion of left MCA. Infarct area was confirmed by using 2, 3, 5-triphenyltetrazolium chloride stain. The immunoreactivities of poly (ADP-ribose) reflecting activity of enzyme PARP and activated caspase-3 were compared in infarct, peri-infarct and normal zones in 3-AB group and 12 controls. RESULTS: The volume of infarction was decreased about 34% in 3-AB group compared with controls. In 3-AB group, immunoreactivities of PAR were significantly reduced in ischemic regions, especially peri-infarct zone, but those of activated caspase-3 were significantly increased in same region. CONCLUSIONS: These results suggest that treatment of PARP inhibitor can reduce the infarct volume by converting necrotic cell death into apoptosis. PARP inhibition can be another potential neuroprotective strategy in ischemic stroke.

BACKGROUND: The efficacy of antiretroviral therapy (ART) has improved, and the adverse effects of antiretroviral drugs have been reduced. However, these adverse effects still significantly influence patient compliance, increasing the risk of tolerability failure. Therefore, we investigated the adverse effects and tolerability failure causing changes in the first ART regimen, and identified the regimens that were most vulnerable to switching. MATERIALS AND METHODS: We enrolled patients with human immunodeficiency virus (HIV) who commenced their first ART between January 1, 2011 and July 30, 2014. Patients who started their first ART regimen at the Kyungpook National University Hospital were included in the study if they were aged > or =18 years and were followed-up for > or =12 weeks. The primary dependent variable was the duration of treatment on the same ART regimen. We analyzed the maintenance rate of the first ART regimen based on the treatment duration between these groups using survival analysis and log rank test. The frequency of the adverse effects of ART regimens was analyzed by multiple response data analysis. RESULTS: During the investigation period, 137 patients were enrolled. Eighty-one patients were maintained on the initial treatment regimen (59.1%). In protease inhibitor (PI)-based regimen group, 54 patients were maintained on the initial treatment regimen (54/98, 55.1%). In non-nucleoside reverse transcriptase inhibitor (NNRTI)-and integrase inhibitor (II)-based regimen group, 15 (15/26, 57.7%) and 12 (12/13, 92.3%) patients were maintained on the initial treatment regimen, respectively. Adverse effects that induced ART switching included rash (16/35, 45.7%), gastrointestinal discomfort or pain (7/35, 20%), diarrhea (7/35, 20%), hyperbilirubinemia (6/35, 17.1%), headache or dizziness (3/35, 8.5%). Among the treatment regimens, the group receiving an II-based regimen showed the least switching. The group receiving PI-and NRTI-based regimens were most likely to switch due to adverse effects during the early treatment period. However, after about 18 months, switching was rarely observed in these groups. Among the PI drugs, darunavir/ritonavir showed fewer drug changes than atazanavir/ritonavir (P = 0.004, log rank test) and lopinavir/ritonavir (P = 0.010). Among the NNRTI drugs, rilpivirne produced less switching than efavirenz (P = 0.045). CONCLUSION: Adverse effects to ART resulted in about a quarter of patients switching drugs during the early treatment period. II-based regimens were advantageous because they were less likely to induce switching within 18 months of treatment commencement. These findings indicated the importance of considering and monitoring the adverse effects of ART in order to improve adherence.

BACKGROUND: The effects of diallyl disulfide (DADS), a garlic derived compound, on the viability and cell signaling- like the downstream signaling through cytochrome c, caspase-3, poly (ADP-ribose) polymerase (PARP) during an oxidative-stress induced injury were studied using H2O2 treated neuronal-differentiated PC12 cells by a nerve growth factor. METHODS: To evaluate the toxicity of the DADS itself, the viability of the differentiated PC12 cells treated with several concentrations of DADS was evaluated with 3, (4, 5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide (MTT) assays. To evaluate the protective effect of the low concentration of DADS from oxidative stress, the viability of the cells (DADS pretreated vs. not pretreated) was evaluated following the exposure to 100 micro M H2O2. Additionally, the expression of caspase-3, PARP, and cytochrome c was examined using western blot analyses. RESULTS: The viability was not affected at low concentrations of DADS, up to 20 micro M, but, over this concentration, it was decreased. Compared with the cells treated with only 100 micro M H2O2, the pretreatment with low concentrations of DADS before exposure to 100 micro M H2O2 increased the viability and induced the inhibition of caspase-3 activation, PARP cleavage, and cytochrome c release. CONCLUSIONS: These results show that low concentrations of DADS shows neuroprotective effects by affecting the downstream signaling through cytochrome c, caspase-3, and PARP pathway and may be a new potential therapeutic strategy for neurodegenerative diseases associated with oxidative injury.
