BackgroundThe association between baseline renal impairment (RI) and the prognosis of diffuse large B-cell lymphoma (DLBCL) was previously not defined. The aim of this study was to evaluate the prognostic value of RI in patients with DLBCL treated with three-weekly rituximab plus cyclophosphamide, Adriamycin, vincristine, and prednisolone immunochemotherapy (R-CHOP21).MethodsPatients with newly diagnosed de novo DLBCLs treated with ≥1 cycle of R-CHOP21 were analyzed retrospectively. Pretreatment blood samples were collected and the glomerular filtration rate (GFR) was calculated. RI was defined by a GFR of <60 mL/min/1.73 m2 ac-cording to the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) formula.ResultsOf the 185 patients enrolled in the present study, 19 patients (10.3%) had RI. The reasons for baseline RI were pre-existing CKD (N=5), acute kidney injury due to either obstruction (N=2) or electrolyte imbalance (N=2) related to DLBCL, and undefined causes (N=10). Patients with baseline RI showed inferior overall survival (OS) compared to those without RI (P<0.001). In multivariate analysis, RI was identified as an International Prognostic Index (IPI)-independent prognostic indicator. A baseline hemoglobin level of <10 g/dL and the presence of RI effectively discriminated a portion of the patients with far inferior event-free survival and OS among the patients having high or high-intermediate risk can-cers according to either the standard- or the National Comprehensive Cancer Network-IPI.ConclusionPretreatment RI was an independent prognostic marker for inferior OS in patients with DLBCL treated with R-CHOP21 immunochemotherapy.
Background: In the current study, we aimed to investigate the efficacy and safety of intravenous immunoglobulin (IVIg)-SN 10%, a new 10% IVIg formulation, in adult patients with severe primary immune thrombocytopenia (ITP; platelet count < 20 × 109 /L). Methods: Patients diagnosed as primary ITP, aged 19 years old or more, and had a platelet count of < 20 × 109 /L by screening complete blood cell count performed within 2 weeks of study commencement were eligible. Patients received IVIg-SN 10% at a dose of 1 g/kg/day for two consecutive days. Response was defined as the achievement of a platelet count of ≥ 50 × 109 /L at day 8. Results: Out of 81 eligible patients, 31 patients were newly diagnosed, 7 patients had persistent ITP, and 43 patients had chronic ITP. In intent-to-treat analysis, 61.3 patients (75.7%) achieved response and satisfied the pre-defined non-inferiority condition. Median time to response was 2 days and mean duration of maintaining response after the completion of IVIg therapy was 9.13 ± 8.40 days. Response rates were not found to be dependent on the phase of ITP or previous treatment for ITP. The drug was well tolerated and the frequency of mucocutaneous bleeding decreased during the study period. Conclusion: In summary, IVIg-SN 10% formulation was found to be safe and effective in adult ITP patients (Trial registry at ClinicalTrials.gov, NCT02063789).
본 논문에서는 독립 성분 해석(Independent Component Analysis, ICA) 기법과 인근 평균 및 정규화를 이용한 영상 분류 방법을 제안하였다. ICA에 잡음을 주어 영상을 분류하였을 때, 잡음에 대한 강인성을 증가시키기 위하여, 제안된 인근 평균 및 정규화를 전처리로 적용하였다. 제안된 방법은 전처리 없이 ICA에 주성분 해석(Principal Component Analysis, PCA)을 이용한 것에 비해 잡음에 대한 강인성을 증가시키는 것을 모의 실험을 통하여 확인하였다.
Hidradenitis suppurativa (HS) is a chronic inflammatory condition with an unclear etiopathogenesis that is considered to be a follicular occlusive disease. We present a case of HS that was suspected to have developed as a complication of subdermal excision. A 19-year-old man who had undergone subdermal excision due to osmidrosis presented 7 months after surgery with a persistent painful mass in his left axilla. Despite medical treatment, incision, and drainage, a painful enlarged abscess recurred in the left axilla and was cured completely by deroofing surgery. However, 15 months after subdermal excision, he revisited the hospital because of a painful mass in the right axilla. The patient’s condition met the diagnostic criteria of HS. After several recurrences, a cure was achieved by radical wide excision. Mechanical stress like that associated with subdermal excision is considered to be a possible etiological factor of HS. In addition, pathological changes at the sebofollicular junction allow rupture and leakage of folliculopilosebaceous units upon exposure to mechanical stress, which may result in the aggressive subcutaneous extension of inflammation. We suggest that HS should be considered in patients with a recurrent abscess after subdermal excision, and recommend surgical treatment as a possible option if conservative treatment is clinically ineffective.
This study was conducted to evaluate the ressibility of various Dianthus species as ornamental plants based on morphological characteristics and to analyze the genetic relationship among the Dianthus species. D. chinensis, D. curthusiamoum, D. arenorisus, D. superbus and D. barbatus possessing spendour flowering cluster with pink and red color could be suggested for garden plant, with D. caryophyllus having red flower clusters with linear leaf shape for pot flower or garden plant. Twelve oligonucleotide random primers were used to amplify genomic DNA of Dianthus species using polymerase chain reaction. Ninety-five polymorphic bands in the range of 300 to 3,500 bp were obtained from PCR fingerprinting. Similairity matrix of PCR fingerprinting profiles was generated by coefficient value, and the data were subjected to cluster analysis. Thirty-four Dianthus species analyzed were classified into 5 groups with similarity coefficient value of 0.84 and 12 groups with the value of 0.88. PCR fingerprinting rusults showed similar trends as the morphological characteristics of the plants.
