Background: Remote ischemic postconditioning (RIPoC) is induced by several cycles of brief, reversible, mechanical blood flow occlusion, and reperfusion of the distal organs thereby protecting target organs. We investigated if RIPoC ameliorated liver injury in a lipopolysaccharide (LPS)-induced endotoxemic rats. Methods: Protocol 1) Rats were administered LPS and samples collected at 0, 2, 6, 12, and 18 h. 2) After RIPoC at 2, 6, and 12 h (L+2R+18H, L+6R+18H, and L+12R+18H), samples were analyzed at 18 h. 3) RIPoC was performed at 2 h, analysis samples at 6, 12, 18 h (L+2R+6H, L+2R+12H, L+2R+18H), and RIPoC at 6 h, analysis at 12 h (L+6R+12H). 4) Rats were assigned to a control group while in the RIPoC group, RIPoC was performed at 2, 6, 10, and 14 h, with samples analyzed at 18 h. Results: Protocol 1) Liver enzyme, malondialdehyde (MDA), tumor necrosis factor-α (TNF-α), and nuclear factor-κB (NF-κB) levels increased while superoxide dismutase (SOD) levels decreased over time. 2) Liver enzyme and MDA levels were lower while SOD levels were higher in L+12R+18H and L+6R+18H groups when compared with L+2R+18H group. 3) Liver enzyme and MDA levels were lower while SOD levels were higher in L+2R+6H and L+6R+12H groups when compared with L+2R+12H and L+2R+18H groups. 4) Liver enzyme, MDA, TNF-α, and NF-κB levels were lower while SOD levels were higher in RIPoC group when compared with control group. Conclusions RIPoC attenuated liver injury in the LPS-induced sepsis model by modifying inflammatory and oxidative stress response for a limited period.

Purpose: There is a lack of a report about the trajectories of allergen sensitization, although it is important to understand the change of allergen sensitization to manage allergic disease. This study aimed to analyze the change and trajectories of allergen sensitization in children with respiratory and allergic diseases. Methods: From 2006 to 2020, children with respiratory and allergic diseases or screened for allergic sensitization were evaluated. We visualized the alterations and the trajectories of allergen sensitization using stacked area graphs, box plots, and Sankey diagrams. Results: A total of 2,804 subjects were included, and allergic rhino-conjunctivitis was diagnosed in 1,931 children (68.9%). The mean age for the first test was 4.1 years, and that for the second test was 6.5 years. Children sensitized to class 1 food allergen before age 5 showed sensitizations more for other allergens and at a younger age after age 5 than children who were not. The atopic tendency continued once it had been obtained before the early school age in the persistence or the new development of sensitization. Conclusion Allergen sensitization has changed over time and has shown different patterns according to age. Its trajectory has taken a wide variety of courses in children with respiratory and allergic diseases until the early school age. These changes reflect the allergic diseases and socio-environmental characteristics of children and adolescents.

BACKGROUND: Cardiovascular diseases of chronic dialysis patients are often undertreated because of their higher surgical risk. This study aimed to assess mortality and morbidity after open heart surgery in chronic dialysis patients compared to those with normal renal function and identify risk factors for postoperative outcomes. METHODS: We retrospectively analyzed 2,432 patients who underwent open heart surgery from 2002 to 2017 and collected data from 116 patients (38 patients on dialysis and 78 age-, sex-, and diabetes mellitus status-matched control patients with normal kidney function). We assessed comorbidities, New York Heart Association (NYHA) class, laboratory data, surgical methods, and postoperative outcomes. RESULTS: The dialysis group had more comorbidities, higher NYHA classes, and greater need for urgent surgeries compared to the control group. They exhibited significantly higher postoperative mortality (18.4% vs. 2.6%, P = 0.005) and more overall complications (65.8% vs. 25.6%, P < 0.001). Dialysis itself significantly increased relative risk for in-hospital mortality after adjustment. EuroSCORE II was not as useful as in the general population. Multivariate logistic regression analysis demonstrated that total (adjusted odds ratio [AOR], 10.7; P = 0.029) and in-hospital death risk (AOR, 14.7; P = 0.033), the durations of postoperative hospitalization (AOR, 4.6; P = 0.034), CRRT (AOR 36.8; P = 0.004), and ventilator use (AOR, 7.6; P = 0.022) were significantly increased in the dialysis group. CONCLUSION: The dialysis group exhibited a higher risk for mortality and overcall complications after open heart surgery compared to the patients with normal renal function. Therefore, the benefit of surgical treatment must be balanced against potential risks.

BACKGROUND: Phospholipase A2 receptor (PLA2R) has been identified as a major autoantigen in primary membranous nephropathy (MN). We evaluated the association between anti-PLA2R antibodies and clinical outcome in Korean patients with primary MN. METHODS: A total of 66 patients with biopsy-proven MN were included. Serum level of anti-PLA2R antibodies was measured by enzyme-linked immunosorbent assay. Biochemical parameters were estimated initially and at follow-up. RESULTS: Anti-PLA2R antibodies were detected in 52.1% and 27.8% of patients with primary and secondary MN, respectively. Forty-eight patients with primary MN were grouped based on presence or absence of anti-PLA2R antibodies. Proteinuria was more severe in anti-PLA2R-positive patients than in anti-PLA2R-negative patients (urine protein/creatinine ratio 7.922 ± 3.985 g/g vs. 4.318 ± 3.304 g/g, P = 0.001), and anti-PLA2R antibody level was positively correlated with proteinuria. The incidence of chronic kidney disease stage ≥ 3 was higher in anti-PLA2R-positive patients compared with anti-PLA2R-negative patients (P = 0.004). The probabilities of spontaneous remission were higher in anti-PLA2R-negative patients compared with anti-PLA2R-positive patients (P < 0.001). Multivariate analysis demonstrated that anti-PLA2R antibodies are an independent risk factor for developing chronic kidney disease stage ≥ 3 and for not reaching spontaneous remission. CONCLUSION: Detection of anti-PLA2R antibodies at diagnosis in patients with primary MN can predict prognosis and guide treatment decisions.

PURPOSE: To Compare the improvement of erectile dysfunction (ED) and lower urinary tract symptoms (LUTS) as well as the efficacy of mirodenalfil 50mg once daily and 100mg on-demand in patients with benign prostatic hyperplasia (BPH) and erectile dysfunction (ED). MATERIALS AND METHODS: Prospective study was done with 220 patients who had BPH and ED from June 2013 to October 2014. Out of 220 individuals, 260 met inclusion criteria and 204 finished the research. Patients were divided into two groups. Group 1 had mirodenafil 50mg once daily and Group 2 had mirodenafil 100mg on-demand. The five-item version of the International Index of Erectile Function (IIEF-5), International Prostate Symptom Score (IPSS), Qmax, and residual urine volume(PVR) were assessed immediately before initiation of treatment (V1) and after four (V2) and twelve weeks of treatment (V3). RESULTS: No difference of IIEF-5, IPSS, Qmax, and PVR between two groups in V1. At V3, both groups had improvements of IPSS and group 1 had better improvements (-5.1+/-4.4 vs. -3.1+/-3.9 p<0.001). And Group 1 had larger improvements than Group 2 in Qmax significantly. No difference in PVR in both groups comparing V1 vs. V2 and V1 vs V3. Group 1 had better improved IIEF-5 than Group 2 (V1 vs. V3: 4.8+/-5.8 vs. 4.4+/-5.1; p=0.032). There was no drop out patients due to cardiovascular problems. CONCLUSIONS: Once daily mirodenafil 50mg was more efficacious in treating both ED and LUTS than on-demand dosing mirodenafil 100mg without any complication of cardiovascular problems.

BACKGROUND/AIMS: Liver stiffness (LS) as assessed by transient elastography (TE) can change longitudinally in patients with chronic hepatitis B (CHB). The aim of this study was to identify the factors that improve LS. METHODS: Between April 2007 and December 2012, 151 patients with CHB who underwent two TE procedures with an interval of about 2 years were enrolled. Ninety-six of the 151 patients were treated with nucleos(t)ide analogues [the antiviral therapy (+) group], while the remaining 55 patients were not [the antiviral therapy (-) group]. The two groups of patients were stratified according to whether they exhibited an improvement or a deterioration in LS during the study period (defined as an LS change of < or =0 or >0 kPa, respectively, over a 1-year period), and their data were compared. RESULTS: No differences were observed between the antiviral therapy (+) and (-) groups with respect to either their clinical characteristics or their initial LS. The observed LS improvement was significantly greater in the antiviral therapy (+) group than in the antiviral therapy (-) group (-3.0 vs. 0.98 kPa, P=0.011). In the antiviral therapy (+) group, the initial LS was higher in the LS improvement group (n=63) than in the LS deterioration group (n=33; 7.9 vs. 4.8 kPa, P<0.001). However, there were no differences in any other clinical characteristic. In the antiviral therapy (-) group, the initial LS was also higher in the LS improvement group (n=29) than in the LS deterioration group (n=26; 8.3 vs. 6.5 kPa, P=0.021), with no differences in any other clinical characteristic. CONCLUSIONS: A higher initial LS was the only factor associated with LS improvement in patients with CHB in this study.

From the endoscopists' point of view, although the main focus of upper gastrointestinal endoscopic examination is the esophagus, stomach, and duodenum (usually bulb and 2nd portion including ampulla of Vater), the portions of the upper airway may also be observed during insertion and withdrawal of the endoscope, such as pharynx and larynx. Thus, a variety of pathologic lesions of the upper airway can be encountered during upper endoscopy. Among these lesions, an epiglottic cyst is relatively uncommon. The cyst has no malignant potential and mostly remains asymptomatic in adults. However, if large enough, epiglottic cysts can compromise the airway and can be potentially life-threatening when an emergency endotracheal intubation is needed. Thus, patients may benefit from early detection and treatment of these relatively asymptomatic lesions. In this report, we present a case of epiglottic cyst in an asymptomatic adult incidentally found by family physician during screening endoscopy, which was successfully removed without complication, using a laryngoscopic carbon dioxide laser.

BACKGROUND: Aortic banding and debanding models have provided useful information on the development and regression of left ventricular hypertrophy (LVH). In this animal study, we aimed to evaluate left ventricular (LV) deformation related to the development and regression of LVH. METHODS: Minimally invasive ascending aorta banding was performed in rats (10 Sprague Dawley rats, 7 weeks). Ten rats underwent a sham operation. Thirty-five days later, the band was removed. Echocardiographic and histopathologic analysis was assessed at pre-banding, 35 days of banding and 14 days of debanding. RESULTS: Banding of the ascending aorta created an expected increase in the aortic velocity and gradient, which normalized with the debanding procedure. Pressure overload resulted in a robust hypertrophic response as assessed by gross and microscopic histology, transthoracic echocardiography [heart weight/tibia length (g/m); 21.0 +/- 0.8 vs. 33.2 +/- 2.0 vs. 26.6 +/- 2.8, p < 0.001]. The circumferential (CS) and radial strains were not different between the groups. However, there were significant differences in the degree of fibrosis according to the banding status (fibrosis; 0.10 +/- 0.20% vs. 5.26 +/- 3.12% vs. 4.03 +/- 3.93%, p = 0.003), and global CS showed a significant correlation with the degree of myocardial fibrosis in this animal model (r = 0.688, p = 0.028). CONCLUSION: In this animal study, simulating a severe LV pressure overload state, a significant increase in the LV mass index did not result in a significant reduction in the LV mechanical parameters. The degree of LV fibrosis, which developed with pressure overload, was significantly related to the magnitude of left ventricular mechanics.

Hepatocellular carcinoma (HCC) is a critical global health issue and the third most common cause of cancer-related deaths worldwide. The majority of patients who present HCC are already at an advanced stage and their tumors are unresectable. Sorafenib is a multi-kinase inhibitor of the vascular endothelial growth factor pathway and was recently introduced as a therapy for advanced HCC. Furthermore, studies have shown that oral sorafenib has beneficial effects on survival. However, many patients experience diverse side effects, and some of these are severe. Liver abscess development has not been previously documented to be associated with sorafenib administration in HCC. Here, we report the case of a HCC patient that developed a liver abscess while being treated with sorafenib.
