Hydrophobization of Reduced Graphene Oxide Aerogel Using Soy Wax to Improve Sorption Properties.

A special technique has been developed for producing a composite aerogel which consists of graphene oxide and soy wax (GO/wax). The reduction of graphene oxide was carried out by the stepwise heating of this aerogel to 250 °C. The aerogel obtained in the process of the stepwise thermal treatment of rGO/wax was studied by IR and Raman spectroscopy, scanning electron microscopy, and thermogravimetry.

Outcomes of first therapy after CD19-CAR-T treatment failure in large B-cell lymphoma.

Persistence or recurrence of large B-cell lymphoma after CD19-CAR-T is common, yet data guiding management are limited. We describe outcomes and features following CAR-T treatment failure. Of 305 adults who received CD19-CAR-T, 182 experienced disease recurrence or progression (1-year cumulative incidence 63% [95%CI: 57-69]).

Vitamin D Insufficiency and Clinical Outcomes with Chimeric Antigen Receptor T-Cell Therapy in Large B-cell Lymphoma.

Vitamin D insufficiency is a potentially modifiable risk factor for poor outcomes in newly diagnosed large B-cell lymphoma (LBCL). However, the role of circulating vitamin D concentrations in relapsed/refractory LBCL treated with CD19-directed chimeric antigen receptor T-cell therapy (CAR-T) is currently unknown. This was a single-center, observational study that evaluated the association of pre-CAR-T 25-hydroxyvitamin D (25-OHD) status with 100-day complete response, progression-free survival, overall survival, and CAR-T-related toxicity in 111 adult relapsed/refractory LBCL patients.

Clinical outcomes with use of radiation therapy and risk of transformation in early-stage follicular lymphoma.

Between 1998 and 2009, a total of 295 patients (median age 58, 53% females) with newly diagnosed early-stage follicular lymphoma (FL) were managed at Memorial Sloan Kettering Cancer Center. Approximately half of patients (137, 46%) underwent initial observation and half (158, 54%) immediate treatment: radiation alone (n = 108), systemic treatment alone (n = 29), or combined modality treatment (n = 21). Median follow-up was 8.

Impact of Genomic Alterations in Large B-Cell Lymphoma Treated With CD19-Chimeric Antigen Receptor T-Cell Therapy.

Purpose: Tumor-intrinsic features may render large B-cell lymphoma (LBCL) insensitive to CD19-directed chimeric antigen receptor T cells (CAR-T). We hypothesized that TP53 genomic alterations are detrimental to response outcomes in LBCL treated with CD19-CAR-T.

Materials And Methods: Patients with LBCL treated with CD19-CAR-T were included.

Population Pharmacokinetics of Melphalan in a Large Cohort of Autologous and Allogeneic Hematopoietic Cell Transplantation Recipients: Towards Individualized Dosing Regimens.

Background And Objectives: High-dose melphalan is an integral part of conditioning chemotherapy prior to both autologous and allogeneic hematopoietic cell transplantation. While underexposure may lead to relapse, overexposure may lead to toxicities include mucositis, diarrhea, bone marrow suppression, and rarely sinusoidal obstruction syndrome. In this study, we describe the population pharmacokinetics of high-dose melphalan as a first step towards individualized dosing.

Positron-emission tomography-based staging reduces the prognostic impact of early disease progression in patients with follicular lymphoma.

Background: Previous studies reported that early progression of disease (POD) after initial therapy predicted poor overall survival (OS) in patients with follicular lymphoma (FL). Here, we investigated whether pre-treatment imaging modality had an impact on prognostic significance of POD.

Methods: In this retrospective study, we identified 1088 patients with grade I-IIIA FL; of whom, 238 patients with stage II-IV disease were initially treated with rituximab, cyclophosphamide, doxorubicin, vincristine and prednisone (R-CHOP), and 346 patients were treated with rituximab-based chemotherapy.

Targeting CD30 Using Brentuximab Vedotin in the Treatment of Hodgkin Lymphoma.

The expression of CD30 receptors is one of the defining characteristics of the malignant Reed-Sternberg cells of Hodgkin lymphoma (HL). CD30 is rarely expressed by normal cells and is rapidly internalized, making it an ideal therapeutic target for monoclonal antibodies and for antibody-drug conjugates. Brentuximab vedotin is the first antibody-drug conjugate to be approved by regulatory agencies for the treatment of patients with relapsed HL, with a single-agent response rate of 75%.

Cyclosporin A-dependent downregulation of the Na+/Ca2+ exchanger expression.

Cyclosporin A (CsA) is an immunosuppressive drug commonly given to transplant patients. Its application is accompanied by severe side effects related to calcium, among them hypertension and nephrotoxicity. The Na+/Ca2+ exchanger (NCX) is a major calcium regulator expressed in the surface membrane of all excitable and many nonexcitable tissues.

Marked PR interval prolongation simulating ST-segment elevation during exercise testing. A case report.

ST-segment elevation during exercise testing is usually indicative of severe proximal coronary artery disease. In this report, the authors describe a patient who underwent exercise stress testing and developed apparent ST elevation in the inferolateral leads. However, noninvasive imaging studies revealed no evidence of myocardial ischemia or other recognized causes of this exercise electrocardiographic (ECG) finding.

T.I.A. revisited: new wine--old bottle.

TIA has been accepted as a concept of transient cerebral ischemia. There is an ever enlarging body of literature sparking controversies considering its natural history, prognosis, outcomes of clinical trials and usefulness of the concept. Much of the controversy is related to the diverse pathophysiology of TIAs, the selection of patients for clinical trials and the associated risk factor in the studied population.

[Causes of premorbid vascular insufficiency in patients with facial neuritis].

In 110 patients with facial nerve neuritis of different etiology, the author studied diseases which were accompanying the main disorder and those which were in the past history. In most of the cases there were infectious diseases and accompanying disorders of a vascular, endocrine character, diseases of the gastrointestinal tract and chronic tonsillitis. In some of the patients accompanying disorders were of a physiological condition (pregnancy, climacterium).
