<B>BACKGROUND</B><P>Integrated <SUP>18</SUP>fluorine fluorodeoxyglucose (<SUP>18</SUP>F-FDG) positron emission tomography/computed tomography (PET/CT) has shown somewhat variable sensitivity and specificity for mediastinal nodal staging in granulomatous disease endemic areas. The purpose of the study was to prospectively evaluate the efficacy of PET/CT for mediastinal nodal staging in nonsmall cell lung cancer (NSCLC) patients in a tuberculosis-endemic country.</P><B>METHODS</B><P>Prospective assessment of the diagnostic efficacy of integrated PET/CT for detecting mediastinal nodal metastasis was performed in 674 patients (M:F ratio = 502:172; mean age, 61 years) with NSCLC. Patients underwent an integrated PET/CT examination and subsequent surgical nodal staging (by mediastinoscopy only in 121 patients and by thoracotomy in 553). Nodes showing greater <SUP>18</SUP>F-FDG uptake than mediastinum at PET without benign calcification or high attenuation >70 household unit (HU) at unenhanced CT were regarded as being positive for malignancy. The histologic nodal assessment results were used as reference standards.</P><B>RESULTS</B><P>Of 2477 mediastinal nodal stations evaluated in 674 patients, 275 (11%) stations in 180 (27%) patients proved to be malignant. On a per-person basis, the overall sensitivity, specificity, and accuracy of PET/CT for mediastinal nodal staging were 61% (110 of 180), 96% (473 of 494), and 86% (583 of 674), respectively. On a per-nodal station basis, they were 46% (126 of 275), 98% (2154 of 2202), and 92% (2280 of 2477).</P><B>CONCLUSIONS</B><P>Integrated PET/CT provides high specificity and reasonably high accuracy, but somewhat low sensitivity for mediastinal nodal staging of NSCLCs. The high specificity is achieved at the expense of sensitivity by interpreting calcified nodes or nodes with high attenuation at CT, even with high FDG uptake at PET, as benign in a tuberculosis-endemic region.

Kim, Young Ae,Yun, Young Ho,Chang, Yoon Jung,Lee, Jongmog,Kim, Moon Soo,Lee, Hyun-Sung,Zo, Jae Ill,Kim, Jhingook,Choi, Yong Soo,Shim, Young Mog,Yoon, Seok-Jun by Lippincott Williams Wilkins. 2014 Annals of surgery Vol.259 No.3

OBJECTIVE:: To investigate the employment status of lung cancer survivors and the work-related problems they face. BACKGROUND:: Although the number of lung cancer survivors is increasing, little is known about their employment and work-related issues. METHODS:: We enrolled 830 lung cancer survivors 12 months after lung cancer curative surgery (median time after diagnosis, 4.11 years) and 1000 volunteers from the general population. All participants completed the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire, Core 30-item and a questionnaire that included items relating to their jobs. We used logistic regression analysis to identify independent predictors of unemployment. RESULTS:: The employment rate of lung cancer survivors decreased from 68.6% at the time of diagnosis to 38.8% after treatment, which was significantly lower than the employment rate of the general population (63.5%; adjusted odds ratio = 2.31, 95% confidence interval: 1.66–3.22). The posttreatment unemployment rate was higher for women than for men. Among survivors, employment was inversely associated with older age, household income, number of comorbidities, and poor social functioning. Fatigue (78.6%) was the most common work-related problem reported by survivors. CONCLUSIONS:: Lung cancer survivors experienced more difficulties in employment than did the general population. Age, monthly household income, number of comorbidities, and social functioning appear to be important factors influencing employment status. These findings suggest that lung cancer survivors need support to cope with the financial impact of cancer.

S. aureus, S. epidermidis, P. aeruginosa, P. acnes와 C. albicans는 사람의 피부에서 발생하는 질병과 밀접한 관련을 가지는 대표적인 병원성 미생물로 알려져 있다. 본 연구에서는 해조류 중에서도 항균 활성에 대한 연구가 미미한 모자반을 대상으로 피부 병원균에 대한 항균 효과를 조사하였다. 국내의 연해에 자생하는 7종의 모자반 추출물 중에서 disc diffusion assay와 MIC assay를 통해 가장 뛰어난 항균 효과를 나타낸 톱니모자반을 후속 연구를 위한 후보 물질로 선정하고 연구를 진행하였다. 톱니모자반 추출물의 유기용매 분획층 중에서, 노말-헥세인 분획층이 S. aureus, S. epidermidis, P. aeruginosa, P. acnes 및 C. albicans에 대한 MIC값이 32-256 μg/mL로 가장 뛰어난 항균 활성을 나타내었다. 이에 피부 병원균들에 대한 치료제로 사용되고 있지만 내성균의 출현으로 효능이 거의 없는 항생제들인 테트라사이클린, 에리트로마이신, 린코마이신과 플루코나졸과 항균 활성이 뛰어난 것으로 나타난 톱니모자반의 노말-헥세인 분획층과의 병용 사용에 의한 항균 시너지 효과를 조사하였다. 그 결과, 톱니 모자반 노말-헥세인 분획층과 이들 항생제와의 병용 사용에 의해 피부 병원균에 대한 항생제와 톱니모자반 노말-헥세인 분획층의 MIC값이 4-32배 감소되었고, 톱니모자반 노말-헥세인 분획층과 이들 항생제와의 병용 시 median FIC값이 0.26-0.55로 항균 시너지 효과를 나타내었다. 즉, 항생제와 톱니모자반 노말-헥세인 분획층과의 병용 사용은 피부 병원균에 대한 이들 항생제의 감수성을 회복시키는데 크게 기여하는 것으로 나타났다. The object of this study was to develop an alternative way to treat human skin pathogens using marine algae. During this study, we observed that the ethanolic extract of the edible brown algae [Sargassum serratifolium (C. Agardh) C. Agardh] exhibited potential antimicrobial activity against pathogenic commensal bacteria related with acne vulgaris (Propionibacterium acnes, Staphylococcus epidermidis, Staphylococcus aureus and Pseudomonas aeruginosa), and Candida albicans which causes cutaneous candidiasis. Among the solvent-soluble fractions from the ethanolic extract, a hexane-soluble fraction showed the strongest antimicrobial activity against all tested human skin pathogens with MIC values ranging from 32 to 512 μg/mL. In addition, the hexane fraction exhibited a synergistic antimicrobial activity with commercial antibiotics used in the treatment of acne vulgaris or cutaneous candidiasis. Thus, this study suggests that S. serratifolium extract could be a potential source of natural antimicrobial agents or a pharmaceutical component against human skin pathogens.

Norovirus, which causes gastroenteritis in humans, is an important food-borne pathogen worldwide. In an effort to discover an antiviral substance against norovirus, extracts from several seaweeds were evaluated for antiviral activity against feline calicivirus (FCV), which was used as a surrogate. The methanolic extract of Undaria pinnatifida exhibited the most significant antiviral activity and virucidal efficacy against FCV. The concentrations of the extract that reduced viral replication by 50% ($EC_{50}$) and resulted in the death of 50% of the host cells ($CC_{50}$) were 0.05 mg/mL and 1.02 mg/mL, respectively. The selectivity index, calculated from the ratio of the $CC_{50}$ and $EC_{50}$ was 20.4. No FCV infection of host cells occurred following a 1-h incubation in the presence of 12.50 mg/mL U. pinnatifida extract, indicating that the virus was completely inactivated by the extract treatment. The results obtained in this study will contribute to the development of a natural antiviral substance that will prevent food-borne disease caused by norovirus.

Kim, Bogeum,Kim, Min-Sung,Park, Seul-Ki,Ko, Seok-Chun,Eom, Sung-Hwan,Jung, Won-Kyo,Kim, Young-Mog The Korean Society of Fisheries and Aquatic Scienc 2018 Fisheries and Aquatic Sciences Vol.21 No.7

Background: Cutaneous bacterial pathogens including Staphylococcus aureus, Staphylococcus epidermidis, Pseudomonas aeruginosa, and Propionibacterium acnes are often involved in acne vulgaris. The currently available therapeutic option for these skin pathogens is an antibiotic treatment, resulting in the emergence of antibiotic-resistant bacteria. The objective of this study was to discover an alternative antibacterial agent with lower side effect from marine algae. Results: The ethanolic extract of edible brown algae Ishige okamurae exhibits potent antibacterial activity against cutaneous bacterial pathogens. Among the ethanol soluble fractions, the n-hexane (Hexane)-soluble fraction exhibited the strongest antibacterial activity against the pathogens with MIC values ranging 64 to $512{\mu}g/mL$ and with minimum bactericidal concentration values ranging 256 to $2048{\mu}g/mL$. Furthermore, the combination with Hexane fraction and antibiotics (ceftazidime, ciprofloxacin, and meropenem) exhibited synergistic effect. Conclusion: This study revealed that the I. okamurae extract exhibited a synergistic antibacterial effect against acnerelated cutaneous bacterial pathogens acquired antibiotic resistant. Thus, the results of the present study suggested that the edible seaweed extract will be a promising antibacterial therapeutic agent against antibiotic-human skin pathogens and its infections.

<P><B>Objectives</B></P><P>The objectives of this study were to compare the clinical features and the outcomes after thymectomy between patients with and without thymoma and to evaluate the influence of thymectomy on the subsequent clinical course of myasthenia gravis.</P><P><B>Methods</B></P><P>Between 1995 and 2003, 64 consecutive patients underwent thymectomy, and of these, 60 patients were followed up for at least 12 months postoperatively. The study population was divided into 2 groups based on the presence of thymoma. We performed a retrospective analysis to compare the neurologic outcomes of thymectomy between patients with thymomatous myasthenia gravis and those with nonthymomatous myasthenia gravis.</P><P><B>Results</B></P><P>Twenty-four patients had a thymoma. No significant differences were observed between the 2 groups regarding the preoperative severity of myasthenia gravis. There was no significant difference in the follow-up duration between the 2 groups. There was no significant difference in the overall remission rate between the 2 groups (<I>P</I> = .064). The mean time required to reach a remission was 10.6 months and 23.5 months in the thymoma and nonthymoma groups, respectively. The mean duration of remission was 43.1 months and 30.8 months in the thymoma and nonthymoma groups, respectively.

Kim, Tae Hyun,Cho, Kwan Ho,Pyo, Hong Ryull,Lee, Jin Soo,Zo, Jae Ill,Lee, Dae Ho,Lee, Jong Mog,Kim, Hyae Young,Hwangbo, Bin,Park, Sung Yong,Kim, Joo Young,Shin, Kyung Hwan,Kim, Dae Yong Radiological Society of North America 2005 Radiology Vol.235 No.1

<P>PURPOSE: To retrospectively evaluate dose-volumetric parameters for association with risk of severe (grade >/=3) radiation pneumonitis (RP) in patients after three-dimensional (3D) conformal radiation therapy for lung cancer. MATERIALS AND METHODS: The study was approved by the institutional review board, which did not require informed consent. Data from 76 patients (66 men, 10 women; median age, 60 years; range, 35-79 years) with histologically proved lung cancer treated curatively with 3D conformal radiation therapy between August 2001 and October 2002 were retrospectively analyzed. Twenty patients underwent surgery before radiation therapy; 57 patients received chemotherapy. Median total radiation dose of 60 Gy (range, 54-66 Gy) was delivered in 30 (range, 27-33) fractions over 6 weeks. RP was scored by using Radiation Therapy Oncology Group criteria. Clinical parameters were analyzed. Dose-volumetric parameters analyzed were percentage of lung volume that received a dose of 20 Gy or more (V20), 30 Gy or more (V30), 40 Gy or more (V40), or 50 Gy or more (V50); mean lung dose (MLD); normal tissue complication probability (NTCP); and total dose. Fisher exact test was performed to compare clinical parameters between patients who developed severe RP and those who did not. Univariate and multivariate logistic regression analyses were performed to evaluate data for association between dose-volumetric parameters and severe RP. Pearson chi(2) test was used to assess data for correlations among dose-volumetric parameters. P < or = .05 was considered to indicate statistically significant difference. RESULTS: Of 76 patients, 30 (39%) did not develop RP; 23 (30%) developed RP of grade 1; 11 (14%), grade 2; 11 (14%), grade 3; and 1 (1%), grade 4. None had grade 5 RP. Age (< 60 vs > or =60), sex, Karnofsky performance status (< 70 vs > or =70), forced expiratory volume in 1 second, presence of weight loss, preexisting lung disease, history of thoracic surgery, and history of chemotherapy did not significantly differ between patients who developed severe RP and those who did not. In univariate analyses, MLD, V20, V30, V40, V50, and NTCP were associated with severe RP (P < .05). In multivariate analysis, MLD was the only variable associated with severe RP. CONCLUSION: MLD is a useful indicator of risk for development of severe RP after 3D conformal radiation therapy in patients with lung cancer.</P>
