Therapy-related myelodysplastic syndrome/acute myelogenous leukemia (t-MDS/AML) is extremely rare in chronic lymphocytic leukemia (CLL) despite extensive use of alkylating agents. We present a case of heavily treated CLL with resultant therapy-related refractory anemia with ringed sideroblasts (RARS). A complex cytogenetic abnormality including involvement of 3q21 was detected and to our knowledge, is the first report of a RARS case with a 3q21 abnormality. (C) 2001 Elsevier Science Inc.

- Abstract
PEGylation of quantum dots (QDs) to decrease their toxicity, increase blood circulation time, reduce non-specific uptake and also to solubilize and stabilize hydrophobic QDs in aqueous medium is a widely used approach and many different methods were developed to achieve this. QDs that are luminescent in the near-infrared region (NIR) have recently emerged as the more appropriate materials for bio-imaging studies. In this work, we describe a single step emission tunable aqueous synthesis of PEGylated Ag
2 S NIRQDs. They are highly cytocompatible, not only due to the PEG coating but also due to the intrinsic biocompatibility of Ag2 S, and prepared in a single step aqueous method using thiolated PEGs as the only coating material. Tuning the emission wavelength within the medical window (775–930 nm) with a quantum yield between 2 and 65% is achieved by changing the reaction variables such as PEG molecular weight, pH and precursor ratios. Ag2 S–PEG NIRQDs prepared from 5 kDa MPEG-SH at acidic pH provided a dramatic enhancement in the luminescence intensity. These NIRQDs were also designed with surface functional groups to attach folic acid and loaded with doxorubicin (DOX) which dramatically enhanced the uptake and efficacy of DOX (50% cell death with 15 nM DOX) in FA-receptor overexpressed cancer cell lines (HeLa). They also showed a strong cytoplasmic NIR signal in the in vitro studies, demonstrating great theranostic potential. [ABSTRACT FROM AUTHOR]- Published

- Abstract
Objective: Endothelial progenitor cells (EPC) have a regenerative role in the vascular system. In this study, we aimed to evaluate simultaneously the effects of EPC and inflammatory cells on the presence and the extent of coronary artery disease (CAD) and the grade of coronary collateral growth in patients with clinical suspicion of CAD.Methods: This study has a cross-sectional and observational design. We enrolled 112 eligible patients who underwent coronary angiography consecutively (mean age: 59±9 years). The association of circulating inflammatory cells and EPC (defined by CD34+KDR+ in the lymphocyte and monocyte gate) with the presence, severity and extent of CAD and the degree of collateral growth were investigated. Logistic regression analysis was used to define the predictors of collateral flow.Results: Of 112 patients 30 had normal coronary arteries (NCA, 27%, 55±9 years) and 82 had CAD (73%, 61±8 years). Among the patients with CAD, the percent degree of luminal stenosis was <50% in 12 patients; 50-90% in 35 patients; and ≥90% in the other 35 patients. Circulating inflammatory cells were higher (leukocytes, 7150±1599 vs 8163±1588 mm(-3), p=0.001; neutrophils, 4239±1280 vs 4827±1273 mm(-3), p=0.021; monocytes, 512±111 vs 636±192 mm(-3), p=0.001) and EPCs were lower (0.27±0.15% vs 0.17±0.14%, p<0.001; 21±15 vs 13±12 mm(-3), p=0.004) in CAD group than NCA group. When we investigated the collateral growth in patients having ≥90% stenosis in at least one major coronary artery, we found that the patients with good collateral growth had significantly higher EPC (0.22±0.17% vs 0.10±0.05%, p=0.009; 18±15 vs 7±3 mm(-3), p=0.003) in comparison to patients with poor collateral growth. Presence of EPC was associated with reduced risk for coronary artery disease (OR: 0.934, 95%CI: 0.883-0.998, p=0.018) and was an independent predictor for good collateral growth (OR: 1.295, 95%CI: 1.039-1.615, p=0.022). A sum of CD34+KDR-, CD34+KDR+ and CD34-KDR+ cells (192±98 mm(-3)), and a CD34-KDR- cell subpopulation within monocyte gate (514±173 mm(-3)) reached to highest counts in good collateral group among all study population.Conclusion: Endothelial progenitor cells can be mobilized from bone marrow to induce the coronary collateral growth in case of myocardial ischemia even in presence of the vascular risk factors and extensive atherosclerosis. This finding may be supportive to investigate the molecules, which can specifically mobilize EPC without inflammatory cells. [ABSTRACT FROM AUTHOR]- Published

Liver transplantation is a technically complex and long surgical procedure. A large quantity of various materials such as catheters, sutures, needles and clips are frequently used during the procedure. These materials may enter in the liver from the vascular or biliary orifices inadvertently. A 50-year-old patient who had hepatic failure due to HBV underwent a deceased-donor liver transplantation. The deceased donor was a 75-year-old HbsAg+ man. The recipient had subfebrile fever and leukocytosis post-operatively. A control computed tomography revealed a cuneiform ischemic area, and a foreign body inside the right anterior portal vein branch proximal to this ischemic region. A 10-F Nelaton catheter, 5-cm long, was removed from the portal vein by surgery. Retrospectively, we understood that the portal vein was cut during the backtable procedure and the portal vein catheter was replaced with a larger one for better irrigation. Most probably, the original catheter was cut together with the portal vein, and the tip of the catheter was retained in the portal system and migrated into the liver. As far as we know, such a complication of liver transplantation has never been described previously. [ABSTRACT FROM AUTHOR]

Enoxaparin sodium is a low molecular weight heparin (LMWH) used to treat and prevent deep venous thrombosis (DVT). The common complications related to the use of heparin are bleeding, allergic reaction, and osteoporosis. A less common complications are thrombocytopenia and thromboembolism that may not be generally recognized. We present a case of low molecular weight (LMW) heparin-induced thrombocytopenia (HIT) causing stroke, lower extremity arterial occlusion, and skin necrosis. Monitoring the platelet count is essential for early diagnosis of HIT. All patients who undergo heparinization should have a baseline platelet count done before the regimen is started and should be monitored closely especially during the first weeks of treatment.

- Abstract
The effect of air on atom transfer radical polymerization (ATRP) of phenethyl methacrylate (PEMA) was investigated. The results indicated that air alone induced polymerization in the absence of an added initiator with the ATRP catalyst complexes NiBr
2 (Pn-Bu3 )2 and Cu(n)Xn /ligand (n = 1, 2; X = Cl, Br; ligand = dipyridyl (dpy) or pentamethyldiethylenetriamine (PMDETA)) at high temperatures. Molecular weights of the polymers were not predictable, but the polydispersities were low. Polymers with very low polydispersities (1.08) and high molecular weights (704 000) were obtained with CuCl 2 /PMDETA catalyst complex. The results indicate that a reverse ATRP mechanism is probably involved in the air-induced polymerization. The extension of the air-induced polymerization to n-butyl methacrylate shows that the air-induced polymerization should be generic for methacrylates.- Published

Summary Background Isatuximab is an anti-CD38 monoclonal antibody approved in combination with pomalidomide–dexamethasone and carfilzomib–dexamethasone for relapsed or refractory multiple myeloma. This phase 3, open-label study compared the efficacy of isatuximab plus carfilzomib–dexamethasone versus carfilzomib–dexamethasone in patients with relapsed multiple myeloma. Methods This was a prospective, randomised, open-label, parallel-group, phase 3 study done at 69 study centres in 16 countries across North America, South America, Europe, and the Asia-Pacific region. Patients with relapsed or refractory multiple myeloma aged at least 18 years who had received one to three previous lines of therapy and had measurable serum or urine M-protein were eligible. Patients were randomly assigned (3:2) to isatuximab plus carfilzomib–dexamethasone (isatuximab group) or carfilzomib–dexamethasone (control group). Patients in the isatuximab group received isatuximab 10 mg/kg intravenously weekly for the first 4 weeks, then every 2 weeks. Both groups received the approved schedule of intravenous carfilzomib and oral or intravenous dexamethasone. Treatment continued until progression or unacceptable toxicity. The primary endpoint was progression-free survival and was assessed in the intention-to-treat population according to assigned treatment. Safety was assessed in all patients who received at least one dose according to treatment received. The study is registered at ClinicalTrials.gov, NCT03275285. Findings Between Nov 15, 2017, and March 21, 2019, 302 patients with a median of two previous lines of therapy were enrolled. 179 were randomly assigned to the isatuximab group and 123 to the control group. Median progression-free survival was not reached in the isatuximab group compared with 19·15 months (95% CI 15·77–not reached) in the control group, with a hazard ratio of 0·53 (99% CI 0·32–0·89; one-sided p=0·0007). Treatment-emergent adverse events (TEAEs) of grade 3 or worse occurred in 136 (77%) of 177 patients in the isatuximab group versus 82 (67%) of 122 in the control group, serious TEAEs occurred in 105 (59%) versus 70 (57%) patients, and TEAEs led to discontinuation in 15 (8%) versus 17 (14%) patients. Fatal TEAEs during study treatment occurred in six (3%) versus four (3%) patients. Interpretation The addition of isatuximab to carfilzomib–dexamethasone significantly improves progression-free survival and depth of response in patients with relapsed multiple myeloma, representing a new standard of care for this patient population.

- Abstract
Introduction: A proportion of patients with multiple myeloma (MM) are older and/or have comorbidities, requiring dose adjustments. Data from OPTIMISMM (NCT01734928) supported the use of pomalidomide, bortezomib, and dexamethasone (PVd) for treating relapsed/refractory MM. This subanalysis of OPTIMISMM assessed outcome by frailty and/or bortezomib dose adjustment., Methods: Patient frailty (nonfrail vs. frail) was classified using age, Charlson Comorbidity Index, and Eastern Cooperative Oncology Group performance status. Data from patients requiring a bortezomib dose reduction, interruption, and/or withdrawal during PVd treatment were assessed., Results: Among 559 patients, 93 of 281 (33.1%) and 93 of 278 (33.5%) patients who received PVd and bortezomib and dexamethasone (Vd), respectively, were frail. Overall response rate (ORR) and median progression-free survival (PFS) were higher in nonfrail vs. frail with PVd treatment (ORR, 82.8% vs. 79.6%; PFS, 14.7 vs. 9.7 months); significantly higher than with Vd regardless of frailty. Grade ≥ 3 treatment-emergent adverse events (TEAEs) were higher with PVd vs. Vd, regardless of frailty. Discontinuations of PVd were lower in nonfrail vs. frail patients (19.2% vs. 30.1%); the median duration of treatment was similar (DoT; 8.8 vs. 8.9 months, respectively). Patients who received PVd with a bortezomib dose adjustment (n = 240) had a longer median DoT (9.3 vs. 4.5 months) and PFS (12.1 vs. 8.4 months) vs. those without., Conclusion: Frail patients treated with PVd demonstrated a higher ORR and a longer PFS and DoT vs. Vd, despite a higher frequency of grade ≥ 3 TEAEs leading to pomalidomide, bortezomib, and/or dexamethasone discontinuation. Therefore, PVd treatment may improve patient outcomes, regardless of frailty., (Copyright © 2023 The Author(s). Published by Elsevier Inc. All rights reserved.)

- Abstract
Background: In the GLOW study, fixed-duration ibrutinib-venetoclax showed superior progression-free survival versus chlorambucil-obinutuzumab in patients with previously untreated chronic lymphocytic leukaemia who were older or had comorbidities, or both, at a median follow up of 27·7 months. In this Article, we report updated outcomes from GLOW after a 46-month median follow-up., Methods: GLOW was a randomised, multicentre, phase 3 study done at 67 hospital centres across 14 countries. Patients aged 65 years and older or 18-64 years with previously untreated chronic lymphocytic leukaemia and a cumulative illness rating scale score of more than 6 or creatinine clearance less than 70 mL/min, or both, and an Eastern Cooperative Oncology Group performance status of 2 or less were randomly assigned (1:1) via an interactive web system with permuted blocks (block size of four) and stratified by IGHV mutational status and the presence of del11q aberration to the ibrutinib-venetoclax group (three cycles of ibrutinib lead-in [420 mg/day, orally], followed by 12 cycles of ibrutinib plus venetoclax [400 mg/day, orally, including a 5-week dose ramp-up]) or the chlorambucil-obinutuzumab group (six cycles of chlorambucil [0·5 mg/kg, orally, on days 1 and 15 of each cycle], and obinutuzumab [1000 mg, intravenously, on days 1 (or 100 mg on day 1 and 900 mg on day 2), 8, and 15 of cycle 1 and day 1 of cycles 2-6]). The primary endpoint was progression-free survival in the intention-to-treat population, assessed by an independent review committee. The safety population included all randomised patients who received at least one dose of the study treatment. This study is registered with ClinicalTrials.gov (NCT03462719) and the EU Clinical Trials Register (EudraCT 2017-004699-77)., Findings: Between May 4, 2018, and April 5, 2019, 211 patients (122 [58%] were male and 89 [42%] were female) were randomly assigned to receive ibrutinib-venetoclax (n=106) or chlorambucil-obinutuzumab (n=105). At a median of 46 months (IQR 43-47) of follow-up, progression-free survival remained superior for the ibrutinib-venetoclax group (hazard ratio 0·214 [95% CI 0·138-0·334]; p<0·0001); 42-month progression-free survival rates were 74·6% (95% CI 65·0-82·0) for ibrutinib-venetoclax and 24·8% (16·5-34·1) for chlorambucil-obinutuzumab. Following the primary analysis, one patient in the chlorambucil-obinutuzumab group had a serious adverse event of myelodysplastic syndrome. Treatment-related deaths were reported in one patient receiving ibrutinib-venetoclax (cardiac failure, pneumonia, and sinus node dysfunction) and in one patient receiving chlorambucil-obinutuzumab (pneumonia). There were 15 deaths in the ibrutinib-venetoclax group (of which three were due to post-treatment infections) and 30 deaths in the chlorambucil-obinutuzumab group (of which 10 were due to post-treatment infections)., Interpretation: After 4 years of follow-up, ibrutinib-venetoclax continues to significantly prolong progression-free survival (vs chemoimmunotherapy) in patients with previously untreated chronic lymphocytic leukaemia, supporting its use as a first-line option., Funding: Janssen Research & Development and Pharmacyclics., Competing Interests: Declaration of interests CUN received consultancy fees and research funding from AbbVie, Janssen, Octapharma, and AstraZeneca; received research funding from the Novo Nordisk Foundation, Danish Cancer Society, and Alfred Benzon foundation; and provided consultancy to CSL Behring, Genmab, Takeda, and BeiGene.

- Abstract
Background: Patients with chronic lymphocytic leukemia (CLL) have a higher risk of developing other malignancies (OMs) compared to the general population. However, the impact of CLL-related risk factors and CLL-directed treatment is still unclear and represents the focus of this work., Methods: We conducted a retrospective international multicenter study to assess the incidence of OMs and detect potential risk factors in 19,705 patients with CLL, small lymphocytic lymphoma, or high-count CLL-like monoclonal B-cell lymphocytosis, diagnosed between 2000 and 2016. Data collection took place between October 2020 and March 2022., Findings: In 129,254 years of follow-up after CLL diagnosis, 3513 OMs were diagnosed (27.2 OMs/1000 person-years). The most common hematological OMs were Richter transformation, myelodysplastic syndrome (MDS) and acute myeloid leukemia (AML). Non-melanoma skin (NMSC) and prostate cancers were the most common solid tumors (STs).The only predictor for MDS and AML development was treatment with fludarabine and cyclophosphamide with/without rituximab (FC ± R) (OR = 3.7; 95% CI = 2.79-4.91; p < 0.001). STs were more frequent in males and patients with unmutated immunoglobulin heavy variable genes (OR = 1.77; 95% CI = 1.49-2.11; p < 0.001/OR = 1.89; 95% CI = 1.6-2.24; p < 0.001).CLL-directed treatment was associated with non-melanoma skin and prostate cancers (OR = 1.8; 95% CI = 1.36-2.41; p < 0.001/OR = 2.11; 95% CI = 1.12-3.97; p = 0.021). In contrast, breast cancers were more frequent in untreated patients (OR = 0.17; 95% CI = 0.08-0.33; p < 0.001).Patients with CLL and an OM had inferior overall survival (OS) than those without. AML and MDS conferred the worst OS (p < 0.001)., Interpretation: OMs in CLL impact on OS. Treatment for CLL increased the risk for AML/MDS, prostate cancer, and NMSC. FCR was associated with increased risk for AML/MDS., Funding: AbbVie, and EU/EFPIAInnovative Medicines Initiative Joint Undertaking HARMONY grant n° 116026., Competing Interests: TC received honoraria from AbbVie.

- Abstract
Introduction: We aim to evaluate of the relationship between high mobility gene box-1 (HMGB1) levels and clinical, laboratory and histopathological findings at diagnosis and in remission in children with Celiac Disease (CD)., Material and Methods: The study included 36 celiac patients at diagnosis, 36 celiac patients in remission, and 36 healthy controls. Patients with intestinal pathologies other than CD, and accompanying inflammatory and/or autoimmune diseases were excluded. Relationship between HMGB1 levels and clinical, laboratory and histopathological findings were evaluated., Results: A total of 72 celiac patients [36 (18 girls, 18 boys, mean age 9.41±3.9 years) in group 1 and 36 (18 girls, 18 boys, mean age 9.91±3.36 years) in group 2] and 36 healthy controls in group 3 (19 girls, 17 boys, mean age 9.56±4 years) were included. The HMGB1 level was significantly higher in group 1 compared to group 2 and group 3 [36.63 (17.98-54.72) ng/ml vs 20.31 (16.89-29.79) ng/ml, p = 0.028 and 36.63 (17.98-54.72) ng/ml vs 20.38 (17.54-24.53) ng/ml p = 0.012, respectively]. A serum HMGB-1 level of 26.553 ng/ml was found to be a cut-off value for the CD with 61% sensitivity, 83% specificity, 78% positive predictive value, and 68% negative predictive value. Higher HMGB1 values were seen in patients with intestinal findings, anemia, anti-tissue transglutaminase IgA levels that were greater than 10 times upper limit of normal, and patients with a higher degree of atrophy as classified by Marsh-Oberhuber., Conclusions: In conclusion, it was thought that HMGB-1 might be a marker that reflects the severity of atrophy at the time of diagnosis and could be used to control dietary compliance in the follow-up. However, there is need for larger population studies in order to evaluate its value as a serological marker for the diagnosis and follow-up of CD and to find a more reliable cut-off value., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 Elsevier Masson SAS.

- Abstract
Purpose: In GLOW, fixed-duration ibrutinib + venetoclax showed superior progression-free survival (PFS) versus chlorambucil + obinutuzumab in older/comorbid patients with previously untreated chronic lymphocytic leukemia (CLL). The current analysis describes minimal residual disease (MRD) kinetics and any potential predictive value for PFS, as it has not yet been evaluated for ibrutinib + venetoclax treatment., Methods: Undetectable MRD (uMRD) was assessed by next-generation sequencing at <1 CLL cell per 10,000 (<10
-4 ) and <1 CLL cell per 100,000 (<10-5 ) leukocytes. PFS was analyzed by MRD status at 3 months after treatment (EOT+3)., Results: Ibrutinib + venetoclax achieved deeper uMRD (<10-5 ) rates in bone marrow (BM) and peripheral blood (PB), respectively, in 40.6% and 43.4% of patients at EOT+3 versus 7.6% and 18.1% of patients receiving chlorambucil + obinutuzumab. Of these patients, uMRD (<10-5 ) in PB was sustained during the first year post-treatment (EOT+12) in 80.4% of patients receiving ibrutinib + venetoclax and 26.3% receiving chlorambucil + obinutuzumab. Patients with detectable MRD (dMRD; ≥10-4 ) in PB at EOT+3 were more likely to sustain MRD levels through EOT+12 with ibrutinib + venetoclax versus chlorambucil + obinutuzumab. PFS rates at EOT+12 were high among patients treated with ibrutinib + venetoclax regardless of MRD status at EOT+3: 96.3% and 93.3% in patients with uMRD (<10-4 ) and dMRD (≥10-4 ) in BM, respectively, versus 83.3% and 58.7% for patients receiving chlorambucil + obinutuzumab. PFS rates at EOT+12 also remained high in patients with unmutated immunoglobulin heavy-chain variable region (IGHV) receiving ibrutinib + venetoclax, independent of MRD status in BM., Conclusion: Molecular and clinical relapses were less frequent during the first year post-treatment with ibrutinib + venetoclax versus chlorambucil + obinutuzumab regardless of MRD status at EOT+3 and IGHV status. Even for patients not achieving uMRD (<10-4 ), PFS rates remained high with ibrutinib + venetoclax; this is a novel finding and requires additional follow-up to confirm its persistence over time.- Published

- Abstract
Background: Many studies have discussed the effects of serum vitamin D deficiency in severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) patients. This study aimed to investigate the relationship between SARS-CoV-2 infection severity and free vitamin D (FVD) and bioavailable vitamin D (BAVD) levels in children., Methods: A prospective case-control study design was used. Participants were divided into three groups based on the World Health Organization COVID-19 Clinical Progression Scale. Serum 25-hydroxyvitamin D (ng/mL), albumin (g/L), and vitamin D binding protein (ng/mL) levels were evaluated to investigate the relationship between disease severity and FVD and BAVD levels., Results: In total, 82 participants were included in the study. Of those, 24.4% were uninfected (n = 20), 50% had a mild case of SARS-CoV-2 (n = 41), and 25.6% had a moderate case (n = 21). There was a statistically significant difference in FVD and BAVD levels between the groups (p = 0.026). Median FVD (p = 0.007, Cohen's d = 0.84) and BAVD (p = 0.007, Cohen's d = 0.86) levels were significantly higher in the mild group compared to the moderate group. FVD and BAVD metabolites were moderately positively correlated with lymphocyte counts (FVD: r = 0.437, p < 0.001; BAVD: r = 0.439, p < 0.001)., Conclusions: This is the first study to demonstrate a relationship between SARS-CoV-2 symptom severity and FVD and BAVD levels. The relationship between FVD and BAVD levels and lymphocyte counts could play an important role in symptom severity and should be evaluated in further studies., (© 2023 Japan Pediatric Society.)

- Abstract
Objective: We evaluated the efficacy and safety of pomalidomide, bortezomib, and dexamethasone (PVd) vs bortezomib and dexamethasone (Vd) by age, renal function, and high-risk cytogenetic abnormalities in lenalidomide-pretreated patients with multiple myeloma at first relapse., Methods: OPTIMISMM was a phase 3, multicenter, open-label, randomized study (NCT01734928; N = 559). The primary endpoint was progression-free survival (PFS)., Results: Overall, 226 patients had received one prior line of therapy. PVd significantly prolonged PFS vs Vd in patients aged ≤65 years (median, 22.0 vs 13.1 months; P = .0258) and >65 years (median, 17.6 vs 9.9 months; P = .0369). Median PFS in patients with renal impairment (RI; creatinine clearance <60 mL/min) was 15.1 months with PVd vs 9.5 months with Vd (hazard ratio [HR], 0.67 [95% CI, 0.34-1.34]). In patients without RI, median PFS was 22.0 vs 13.1 months (HR, 0.45 [95% CI, 0.27-0.76]). In patients with high-risk cytogenetics, median PFS was 14.7 vs 9.9 months (HR, 0.39 [95% CI, 0.13-1.17]). PVd significantly improved overall response rate vs Vd in all subgroups. The safety profile of PVd was consistent with previous reports., Conclusions: These findings confirmed the benefits of PVd at first relapse, including in patients with poor prognostic factors., (© 2021 The Authors.

- Abstract
The aim of this study is to determine the power of he international prognostic scoring systems (IPS-7 and IPS-3) and to obtain indices by integrating leukocyte lymphocyte ratio (LLR) and prognostic nutritional index (PNI) factors as prognostic indicators in cases with classical Hodgkin lymphoma (cHL). 1012 patients with cHL were evaluated with 2 different IPS-4 scores with four parameters: stage, age, hemoglobin level, and either LLR or PNI. Statistical package SPSS v 22.0 was used. Two different Cox regression models were obtained for OS and PFS. Model 1 showed LLR ≥ 5,8 as the highest risk for OS and anemia as the highest risk for PFS. Model 2 showed PNI ≤ 45,2 as the highest risk for OS and anemia as the highest risk for PFS. IPS-4 scores obtained by integrating either LLR or PNI to IPS-3 integration of a biologic parameter either LLR or PNI need to be determined with clinical risk scoring parameters., (Copyright © 2021 Elsevier Ltd.

- Abstract
Paroxysmal nocturnal hemoglobinuria (PNH) is a rare X-linked genetic disorder. On the contrary to its name, it is a multisystemic disease and various symptoms other than hemoglobinuria could be occurred. It could be life threatening especially because of thromboembolic events. In the last decade, a terminal complement inhibition with eculizumab approved with promising results for PNH patients. We conducted this study to evaluate the long term experience of eculizumab therapy from Turkey for the first time. Our cohort included 138 patients with PNH treated with eculizumab between January 2008 and December 2018 at 28 centers in Turkey. Laboratory and clinical findings at the time of diagnosis and after eculizumab therapy were recorded retrospectively. The median age was 39 (range 18-84) years and median granulocyte PNH clone size was 74% (range 3.06-99.84%) at the time of diagnosis. PNH with bone marrow failure syndrome was detected in 49 patients and the rest of 89 patients had classical PNH. Overall 45 patients (32.6%) had a history of any prior thrombotic event before eculizumab therapy and only 2 thrombotic events were reported during the study period. Most common symptoms are fatigue (75.3%), hemoglobinuria (18.1%), abdominal pain (15.2%) and dysphagia (7.9%). Although PNH is commonly related with coombs negativity, we detected coombs positivity in 2.17% of patients. Seven months after the therapy, increased hemoglobin level was seen and remarkably improvement of lactate dehydrogenase level during the treatment was occurred. In addition to previous studies, our real life data support that eculizumab is well tolerated with no serious adverse events and improves the PNH related findings., Competing Interests: None., (AJBR Copyright © 2021.)

- Abstract
The aim of this study is to validate the IPS-3 scoring system as a prognostic indicator in 1012 patients with advanced stage classical Hodgkin Lymphoma (cHL) treated by doxorubicin, bleomycin, vinblastine, dacarbazine (ABVD). According to the IPS-3 scoring system only 3.5 % had high risk and 50.8 % had low risk disease disease and 45.8 % of the cases had intermediate risk disease. Each factors of IPS-7 and IPS-3 scoring systems (age, sex, stage hemoglobin, albumin, lymphocyte count and white cell count) were found to be significant for overall survival (OS) and progression free survival (PFS) according to univariate analyses. Two different multivariate Cox analyses were performed for OS and PFS including the IPS-3/ IPS-7 scoring system parameters. Among 7 risk factors of IPS scoring system, gender and albumin were not found as independent risk factors for both OS and PFS according to cox regression model. But all parameters such as age, stage and hemoglobin those included in IPS-3, were found to be independent significant risk factors for both models obtained for OS and PFS. The results of the study shows that the IPS-3 scoring system can be used as a prognostic indicator in ABVD treated patients in every day practice which is more easily calculate according to the IPS-7., (Copyright © 2021 Elsevier Ltd.

- Abstract
Background: In countries where frontline drug approval is limited to first-generation proteasome inhibitors or immunomodulatory drugs, relapses have been both more frequent and less durable. We investigated real world data on the efficacy and safety of daratumumab monotherapy among patients with relapsed refractory multiple myeloma (RRMM) from Turkey using a prospective early access program., Patients and Methods: A total of 42 patients with RRMM after a minimum of 3 previous lines of proteasome inhibitor/immunomodulatory drug-based treatments were included from 25 centers across Turkey. Daratumumab monotherapy was administered intravenously at a dose of 16 mg/kg weekly (cycles 1-2), on alternate weeks (cycles 3-6), and monthly thereafter., Results: The median daratumumab monotherapy duration was 5.5 months (range, 0.2-28.7 months). The overall response rate was 45.2%, including 14 (33.3%) partial responses, 4 (9.5%) very good partial responses, and 1 (2.4%) complete response. The median duration of response was 4.9 months. The median progression-free survival (PFS) was 5.5 (95% confidence interval, 2.6-8.4 months) with 12- and 18-month PFS rates of 35.7% and 31.0%, respectively. The median overall survival was not reached; the 12- and 18-month overall survival rates were 64.3% and 59.5%, respectively. The depth of response had a significant effect on PFS (log-rank test, P = .026). Overall, of the 76 adverse events reported, 33 (43.4%) were grade ≥ 3; only 4 (9.52%) were grade 3 infusion-related reactions. No infusion-related reactions or adverse events led to treatment discontinuation., Conclusion: The present findings from our daratumumab early access program have confirmed the efficacy and safety profile of daratumumab monotherapy in heavily pretreated Turkish patients with RRMM., (Copyright © 2020 The Authors.

- Abstract
In the randomized phase-3 OPTIMISMM study, the addition of pomalidomide to bortezomib and low-dose dexamethasone (PVd) resulted in significant improvement in progression-free survival (PFS) in lenalidomide-pretreated patients with relapsed or refractory multiple myeloma (RRMM), including lenalidomide refractory patients. Here, we report health-related quality of life (HRQoL) results from this trial. Patients received PVd or Vd in 21-day cycles until disease progression or discontinuation. HRQoL was assessed using the EORTC QLQ-C30, QLQ-MY20, and EQ-5D-3L instruments on day 1 of each treatment cycle. Mean score changes for global QoL, physical functioning, fatigue, side effects of treatment domains, and EQ-5D-3L index were generally stable over time across treatment arms. The proportion of patients who experienced clinically meaningful worsening in global QoL and other domains of interest was similar. These HRQoL results with PVd along with previously demonstrated improvement in PFS vs Vd continue to support its use in patients with RRMM.

- Abstract
Classical Hodgkin lymphoma (cHL) is considered a curable disease; however, approximately one-third of responders experience disease relapse following first-line therapy. Several studies have shown the efficacy of brentuximab vedotin (BV) in patients with relapsed/refractory HL. We present a retrospective analysis of 58 patients with relapsed/refractory HL treated with BV in a named patient program from 11 centers. The median follow-up duration was 20 (range, 4-84) months. The best overall response rate was 64% (complete response [CR], 31%; partial response [PR], 33%). The 5-year progression-free survival (PFS) and overall survival (OS) rates were 12% (95% confidence interval [CI], 0.05-0.22) and 26% (95% CI, 0.16-0.38), respectively. Among patients who achieved CR, the estimated 5-year PFS and OS rates were 32% (95% CI, 0.13-0.54) and 60% (95% CI, 0.33-0.78), respectively. A total of 26 patients underwent subsequent stem cell transplantation. The 5-year PFS and OS rates for 10 patients who had consolidative stem cell transplantation were 28% and 30%, respectively. Twenty-seven patients required further therapy following BV. At the time of the analysis, 12 patients (21%) were alive. Five patients (9%) had long-term remission after achieving CR with BV monotherapy, with a median PFS of 76 months. Three of them (5%) did not receive any other treatment following BV and their median PFS was 75 months. Our long-term results showed that a small subset of patients with relapsed/refractory cHL may benefit from and even be cured with BV monotherapy.

- Abstract
Here, we present a new concept of a core-shell type ionic liquid/metal organic framework (IL/MOF) composite. A hydrophilic IL, 1-(2-hydroxyethyl)-3-methylimidazolium dicyanamide, [HEMIM][DCA], was deposited on a hydrophobic zeolitic imidazolate framework, ZIF-8. The composite exhibited approximately 5.7 times higher CO
2 uptake and 45 times higher CO2 /CH4 selectivity at 1 mbar and 25 °C compared to the parent MOF. Characterization showed that IL molecules deposited on the external surface of the MOF, forming a core (MOF)-shell (IL) type material, in which IL acts as a smart gate for the guest molecules.- Published

- Abstract
Estrogen receptor positive breast cancer is the most common type of breast cancer and in most cases, hormone therapy is considered complementary to surgery. Tamoxifen is one of the most common drugs used in hormone therapy for treating estrogen receptor positive breast cancer cells. However, it has severe side-effects depending on the duration of treating breast cancer and amount of tamoxifen used. In this study, we examined the effects of electroporation on the tamoxifen uptake in estrogen receptor positive MCF-7 breast cancer cells. The survival rate of MCF-7 cells had a negative relationship with energy dissipation in cells. Similarly, the electrical charge delivered to cells during electroporation was inversely proportional to survival rate. The combined application of electroporation and tamoxifen is much more effective than the usage of tamoxifen alone in the treatment of estrogen receptor positive breast cancer. The application of electroporation increased the uptake of tamoxifen into MCF-7 cells and reduced the minimal tamoxifen dosage which, is needed for the treatment of estrogen receptor positive breast cancer.

- Abstract
Background: Studies in tissue engineering about mesenchymal stem cells (MSCs) provide promising results for bone regeneration. The aim of this study was to evaluate the effects of rat bone marrow-derived MSCs (rMSCs) alone and when combined with demineralized bone matrix (DBM) on critical-sized cranial defects of rats., Methods: Ten rats were used to obtain allogeneic rMSCs. Forty rats were separated equally into 4 groups. A full-thickness circular bone defect was created in the frontal bone of the rats. Group 1 was an operative control group. In group 2 DBM, in group 3 rMSCs, and in group 4 DBM combined with rMSCs were applied into the defects. Bone regeneration was evaluated by computed tomographic analysis and immunohistochemistry., Results: In radiological evaluation, the percentage of area healed in group 3 at the 12th week was statistically significantly greater than in group 1. In group 3 and group 4, distributed healing patterns were observed more than in group 2 and in group 1. Immunohistochemical evaluation revealed that group 4 had the best osteoinductive potential. Osteoinductive potential of group 3 was similar to group 2 and was better than group 1., Conclusions: Allogeneic rMSC applications have created a statistically significant radiologic reduction of the bone defect areas at the end of the 12 weeks. The MSC applications have also increased the bone density and changed the healing patterns. Combined use of the DBM and rMSCs has created more osteoinductive responses. This combination can provide better results in craniofacial bone reconstruction.

- Abstract
PEGylation of quantum dots (QDs) to decrease their toxicity, increase blood circulation time, reduce non-specific uptake and also to solubilize and stabilize hydrophobic QDs in aqueous medium is a widely used approach and many different methods were developed to achieve this. QDs that are luminescent in the near-infrared region (NIR) have recently emerged as the more appropriate materials for bio-imaging studies. In this work, we describe a single step emission tunable aqueous synthesis of PEGylated Ag
2 S NIRQDs. They are highly cytocompatible, not only due to the PEG coating but also due to the intrinsic biocompatibility of Ag2 S, and prepared in a single step aqueous method using thiolated PEGs as the only coating material. Tuning the emission wavelength within the medical window (775-930 nm) with a quantum yield between 2 and 65% is achieved by changing the reaction variables such as PEG molecular weight, pH and precursor ratios. Ag2 S-PEG NIRQDs prepared from 5 kDa MPEG-SH at acidic pH provided a dramatic enhancement in the luminescence intensity. These NIRQDs were also designed with surface functional groups to attach folic acid and loaded with doxorubicin (DOX) which dramatically enhanced the uptake and efficacy of DOX (50% cell death with 15 nM DOX) in FA-receptor overexpressed cancer cell lines (HeLa). They also showed a strong cytoplasmic NIR signal in the in vitro studies, demonstrating great theranostic potential.- Published

- Abstract
Introduction: A shortage of deceased donors has compelled the use of extended-criteria donor organs in liver transplantation. The purpose of this study was to evaluate the impact of using deceased donors older than 80 years., Materials and Methods: We retrospectively evaluated 13 patients who received a liver graft from cadaveric donors older than 80 years between December 2007 and March 2014. We analyzed the donor and their recipient characteristics together with morbidity and mortality of recipients., Results: All 13 donors were older than 80 years (median age, 82.7; range, 80-93). There were 9 male and 4 female recipients with an average age of 50.7 (range, 2-65) years. All of the recipients did not have a living donor for liver transplantation. Recipients' mean model for end-stage liver disease (MELD) score was 14.2 (range, 7-20). Graft with macroscopic steatosis was not accepted. Medium follow-up was 19.5 months. The most frequent cause for liver transplantation (LT) was hepatitis B virus (HBV) cirrhosis (8/13 patients). We had 1 case of primary nonfunction, and 4 patients died in 2 weeks after surgery. Of these patients, 2 of them received a split transplant from an 80-year-old cadaver liver. Overall the survival rate after 1 year was 61.5%., Conclusions: Deceased elderly donor usage in LT could expand the donor pool. Liver grafts from donors older than 80 years can be used in necessity or emergency situations. However, care should be taken to avoid early mortality and primary nonfunction. Procedures extending cold ischemia time such as split liver transplantation may increase the risk of primary nonfunction., (Copyright © 2015 Elsevier Inc. All rights reserved.)

Objectives: This study sought to evaluate the effect of liver transplantation on the neuropsychological manifestations of Wilson disease., Materials and Methods: Nine of 42 Wilson disease patients had neuropsychological symptoms before liver transplantation. They were 7 male and 2 female subjects with a median age of 19 years (range 10 to 25). They were analyzed for their preoperative and postoperative hepatic, neurological, and psychological scores described by the Unified Wilson Disease Rating Scale after a mean 36.6 months of follow-up., Results: Preoperative mean Model for End-Stage Liver Disease and Child-Pugh scores were 18.3 (range 15 to 26) and 8.9 (range 6 to 12), respectively. One patient had acute postoperative ischemic stroke unrelated to Wilson disease and was excluded from the statistical analysis. Preoperative and postoperative hepatic, neurological, and psychological scores of the remaining 8 patients were 7.4 ± 2.3 vs 2.4 ± 1.3 (P = .0005), 17.7 ± 11.7 vs 12.7 ± 12.5 (P = .055), and 9.0 ± 1.7 vs 7.0 ± 2.1 (P = .033)., Conclusions: Liver transplantation for Wilson disease can provide some improvement of the neuropsychological symptoms in addition to the hepatic recovery., (Copyright © 2015 Elsevier Inc.

- Abstract
Objectives: Cryptogenic cirrhosis is a common indication for liver transplantation. Diagnosis is made after exclusion of other causes of cirrhosis. In this study, the aim was to evaluate patients with cryptogenic cirrhosis after histopathological examination of explanted liver., Materials and Methods: A retrospective histopathological chart review of 117 patients with cryptogenic cirrhosis who had liver transplantation between November 2009 and June 2014 was performed. Age, sex, operative features, survival rates, and preoperative and postoperative diagnosis were evaluated., Results: During the study period, 123 liver transplantations were performed for these 117 patients. Deceased donor liver transplantations were performed in 23 (18.7%) of the cases. Retransplantations were performed in 5 patients. Median age was 48 years, and female-to-male ratio was 41:76. Hepatosteatosis were observed in 29 patients. Nonalcoholic fatty liver disease and nonalcoholic steatohepatitis were observed in 20 (12%) and 9 (7.7%) of these patients, respectively. Autoimmune hepatitis was observed in 2 patients. The definitive cause of cirrhosis was unclear in 68 (58%) of the patients. Incidental malignant and premalignant lesions were observed in 15 patients., Conclusions: Histopathological examination of the explanted liver after liver transplantation in those patients with cryptogenic cirrhosis may significantly help to diagnose the cause of cirrhosis, such as nonalcoholic steatohepatitis or autoimmune hepatitis, with using the scoring system developed by the International Autoimmune Hepatitis Workgroup. In addition, incidental malignant or premalignant lesions may be observed., (Copyright © 2015 Elsevier Inc. All rights reserved.)

Objectives: This study sought to evaluate the indications, techniques, and results of inferior vena cava (IVC) replacement at living donor liver transplantation (LDLT)., Materials and Methods: We performed 821 LDLTs and 11 (1.3%) patients required concomitant IVC replacement. We analyzed the indications, replacement materials, and outcomes., Results: Right, left, and left lateral liver lobes were transplanted in 7, 2, and 2 patients, respectively. The indications for IVC replacement were thrombosis/fibrosis in 7 patients (Budd-Chiari 4, hereditary tyrosinemia 1, congenital hepatic fibrosis 1, cryptogenic 1), involvement with mass in 3 patients (Echinococcus alveolaris 2, hepatoblastoma 1) and iatrogenic narrowing at IVC in 1 patient. Cryopreserved grafts (aorta n = 5, IVC n = 4, iliac vein n = 1) or synthetic graft (n = 1) were used for replacements. In 1 patient, hepatic outflow obstruction developed at 39 days and was treated successfully by interventional radiology. There was only 1 hospital mortality (8.9%) that was unrelated to caval replacement (subarachnoid hemorrhage). Of the remaining patients, the caval grafts were patent after a mean 7.7 months of follow-up (range 1 to 17 months)., Conclusions: Although rare, IVC replacement can be necessary at LDLT. Budd-Chiari and E. alveolaris are the main underlying diseases for replacement requirements. Caval replacement with cryopreserved vascular grafts can provide successful short-term and long-term patency., (Copyright © 2015 Elsevier Inc. All rights reserved.)
