Natural killer (NK) cells are innate immune cells that are crucial for anticancer activity and have been developed as an immune cell therapy for leukemia. However, their limited effectiveness against solid tumors has prompted research into methods to enhance NK cell activity through combination therapies. Health supplements capable of boosting immune surveillance against tumor cells are gaining attention owing to their potential benefits. Resveratrol, a stilbenoid produced by several plants including peanuts and grapes, reportedly exerts anticancer effects and can activate immune cells. The peanut sprout extract cultivated with fermented sawdust medium (PSEFS) is rich in resveratrol, leveraging its health benefits in terms of the dry weight of herbal products, thus maximizing the utilization of resveratrol’s beneficial properties. Our study compared the efficacy of resveratrol and PSEFS and revealed that PSEFS significantly enhanced NK cell activation compared with an equivalent dose of resveratrol. We investigated the ability of PSEFS to potentiate NK cell anticancer activity, focusing on NK cell survival, tumor cell lysis, and NK cell activation in PSEFS-administered mice. Our findings suggest that PSEFS could be a potential NK cell booster for cancer immunotherapy.

Nephrotic syndrome is associated with a hypercoagulable state, which results in thromboembolism as one of its main complications. Various pathogenetic factors that cause the hypercoagulable state in nephrotic syndrome have been recognized. We report on a 19-year-old female with a minimal-change disease who developed pulmonary thromboembolism combined with intracardiac thrombus while on tapering steroid. Our patient showed hypoalbuminemia with an episode of shock, and was successfully treated with thrombolysis and anticoagulation therapy.

PURPOSE: Negative pressure wound therapy (NPWT) is an adjunct therapy using negative pressure to remove fluid from open wounds through a sealed dressing and a specialized tubing that is connected to a collection container. NPWT is suitable for acute and chronic wound condition because it was designed to accelerate granulation formation on deep wound. Therefore, we performed this study to assess the effectiveness of NPWT for various wound condition in burn center. METHODS: We enrolled 17 patients who were treated with NPWT from January 2014 to April 2016. We analyzed the characteristics and outcomes of the patients through retrospectively. RESULTS: Among 17 patients, there were 13 patients for contact burn, 2 patients for electrical injury, 1 patient for diabetic foot ulcer and 1 patient for Flame burn. Most of the contact burn victims were injured by the exposure of relatively low temperature for a long time and some of them were injured under the condition of sensory deterioration including spinal cord injury, diabetes or sedatives. Wound coverage was accomplished by split thickness skin graft (STSG) in 12 patients. Local flap was done in 1 patient. STSG with local flap was done in 3 patients. And there were 1 patient who got a conservative management. The duration of NPWT application was from 8 days to 101 days (average 36.2 days). CONCLUSION: NPWT showed good clinical outcomes under various wound condition. Therefore, we think that it can be a new treatment paradigm for difficult wound management in burn center.

PURPOSE: High sensitive C-reactive protein (hs CRP) is well known as a strong risk factor of cardiovascular disease (CVD). The aim of this study is to evaluate the impact of elevated hs CRP on coronary artery spasm (CAS) as assessed by intracoronary acetylcholine (ACh) provocation test. MATERIALS AND METHODS: A total of 1729 consecutive patients without significant CVD who underwent coronary angiography and intracoronary ACh test between November 2004 and August 2010 were analyzed. The patients were divided into five groups according to quintiles of hs CRP levels. RESULTS: At baseline, the prevalence of elderly, hypertension, diabetes mellitus, current smoking, and lipid levels were higher in patients with higher hs CRP. During ACh test, the incidences of significant CAS, ischemic electrocardiography (EKG) change, multivessel, and diffuse CAS were higher in patients with higher hs CRP. Multivariate analysis showed that the old age (OR=1.01, CI; 1.0-1.02, p=0.0226), myocardial bridge (OR=3.34, CI; 2.16-5.17, p<0.001), and highest quintile hs CRP (OR=1.54, CI; 1.12-2.18, p=0.008) were independent predictors of ACh induced CAS. However, there was no difference in clinical outcomes up to 12 months. CONCLUSION: In conclusion, higher hs CRP was associated with higher incidence of CAS, worse angiographic characteristics and ischemic EKG change, but was not associated with clinical outcomes.

BACKGROUND/AIMS: An association between past history of hepatitis B virus (HBV) infection and pancreatic cancer (PC) has recently been reported. We investigated whether HBV and hepatitis C virus (HCV) infections are associated with the development of PC in Korea. METHODS: We retrospectively recruited patients with PC and sex- and, age-matched control patients with stomach cancer (SC) during the previous 5 years. Serum HBsAg and anti-HCV were examined, and data on smoking, alcohol intake, diabetes, and the history of chronic pancreatitis (CP) were collected. RESULTS: A total of 506 PC and 1008 SC were enrolled, with respectively 58.1% and 97.3% of these cases being confirmed histologically. The mean age and sex ratio (male:female) were 63.5 years and 1.5:1 in the PC patients and 63.9 years and 1.5:1 in the SC patients respectively (P>0.05). The odds ratios (95% confidence interval, 95% CI) in univariate analysis were 0.90 (0.52-1.56; P=0.70) for HBsAg, 1.87 (0.87-4.01; P=0.11) for anti-HCV, 2.66 (2.04-3.48; P<0.001) for the presence of diabetes, 2.30 (1.83-2.90; P<0.001) for smoking, 1.14 (0.89-1.46; P=0.31) for alcohol intake, and 4.40 (1.66-11.66; P=0.003) for the history of CP. Independent risk factors for PC were presence of diabetes (OR, 2.67; 95% CI, 2.00-3.56; P<0.001), smoking (OR, 2.49; 95% CI, 1.93-3.21; P<0.001) and history of CP (OR, 4.60; 95% CI, 1.56-13.53; P=0.006). CONCLUSIONS: There was no significant association between seropositivity for HBsAg or anti-HCV and PC. Further studies are warranted to clarify the association between HBV infection and PC in regions where HBV is endemic.

BACKGROUND: Angioimmunoblastic T-cell lymphoma (AITL) is a complex lymphoproliferative disorder and often mimics a viral infection with frequent skin involvement. Epstein-Barr virus (EBV) and human herpes virus (HHV)-6 are reported to be associated with AITL, but there are conflicting results. OBJECTIVE: We evaluated the association of EBV and HHV-6 with AITL. METHODS: We reviewed the clinical, histological and immunophenotypical features of 19 cases of AITL. Among them, 11 lymph node biopsies of AITL were examined for HHV-6, -7, and -8 by polymerase chain reaction (PCR) using virus-specific primers. In situ hybridization of EBV early region RNA (EBER) was performed and T cell receptor (TCR) gene rearrangement was also investigated in some cases. RESULTS: Among these 19 cases, maculopapular, plaque or nodular skin lesions accompanied AITL in 12 cases. Clonal TCR gene rearrangement was seen in 8/9 cases tested. EBER in situ hybridization was positive in 8 cases (57.1%). Among 7 cases with skin biopsies, five cases were consistent with cutaneous involvement of AITL, 1 case was a drug eruption, and the other case was Kaposi's sarcoma. Except a HHV-8 (+) case who also had Kaposi's sarcoma, all of these cases were negative for HHV-6, -7 and -8. CONCLUSION: Skin manifestation seems to be a cardinal component of AITL, be it in the context of presentation, progression or recurrent disease. Recognition of clinicopathological features of skin lesions in AITL as diagnostic clues should be stressed among dermatologists. The lack of HHV-6, -7 and -8 in lymph node biopsy of AITL argues against a pathogenic role for HHVs in AITL.

PURPOSE: To investigate the effects of radiation dose-escalation on the treatment outcome, complications and the other prognostic variables for glioblastoma patients treated with 3D-conformal radiotherapy (3D-CRT). MATERIALS AND METHODS: Between Jan 1997 and July 2002, a total of 75 patients with histologically proven diagnosis of glioblastoma were analyzed. The patients who had a Karnofsky Performance Score (KPS) of 60 or higher, and received at least 50 Gy of radiation to the tumor bed were eligible. All the patients were divided into two arms; Arm 1, the high-dose group was enrolled prospectively, and Arm 2, the low-dose group served as a retrospective control. Arm 1 patients received 63~70 Gy (Median 66 Gy, fraction size 1.8~2 Gy) with 3D-conformal radiotherapy, and Arm 2 received 59.4 Gy or less (Median 59.4 Gy, fraction size 1.8 Gy) with 2D-conventional radiotherapy. The Gross Tumor Volume (GTV) was defined by the surgical margin and the residual gross tumor on a contrast enhanced MRI. Surrounding edema was not included in the Clinical Target Volume (CTV) in Arm 1, so as to reduce the risk of late radiation associated complications; whereas as in Arm 2 it was included. The overall survival and progression free survival times were calculated from the date of surgery using the Kaplan-Meier method. The time to progression was measured with serial neurologic examinations and MRI or CT scans after RT completion. Acute and late toxicities were evaluated using the Radiation Therapy Oncology Group neurotoxicity scores. RESULTS: During the relatively short follow up period of 14 months, the median overall survival and progression free survival times were 15+/-1.65 and 11+/-0.95 months, respectively. There was a significantly longer survival time for the Arm 1 patients compared to those in Arm 2 (p=0.028). For Arm 1 patients, the median survival and progression free survival times were 21+/-5.03 and 12+/-1.59 months, respectively, while for Arm 2 patients they were 14+/-0.94 and 10+/-1.63 months, respectively. Especially in terms of the 2-year survival rate, the high-dose group showed a much better survival time than the low-dose group; 44.7% versus 19.2%. Upon univariate analyses, age, performance status, location of tumor, extent of surgery, tumor volume and radiation dose group were significant factors for survival. Multivariate analyses confirmed that the impact of radiation dose on survival was independent of age, performance status, extent of surgery and target volume. During the follow-up period, complications related directly with radiation, such as radionecrosis, has not been identified. CONCLUSION: Using 3D-conformal radiotherapy, which is able to reduce the radiation dose to normal tissues compared to 2D-conventional treatment, up to 70 Gy of radiation could be delivered to the GTV without significant toxicity. As an approach to intensify local treatment, the radiation dose escalation through 3D-CRT can be expected to increase the overall and progression free survival times for patients with glioblastomas.
