A cross-sectional study of university students' awareness, knowledge, and attitudes on organ donation and transplantation in Northern Cyprus.

Background: Understanding the knowledge and attitudes of university students regarding organ transplantation and donation is crucial, as these students can significantly influence public opinion and behavior. This study aims to assess the knowledge and attitudes of North Cyprus University students towards organ transplantation and donation.

Methods: A cross-sectional study was conducted with 400 students from Northern Cyprus University, divided into medical and social science faculties.

Melatonin is effective in attenuating cisplatin-induced neurotoxicity.

Cisplatin (Cis) is a chemotherapeutic agent that has many side effects. Neurotoxicity is one of the most important of these side effects. Oxidative stress and neuroinflammation are the best-known mechanisms in the pathogenesis of neurotoxicity development.

Prognostic Index for Critically Ill Allogeneic Transplantation Patients.

Outcomes of intensive care for allogeneic hematopoietic stem cell transplantation (Allo-SCT) patients remain poor. Better selection of critically ill Allo-SCT patients for intensive care may alleviate costs to the patients, families, and the health care system. We aimed to develop a prognostic index tailored for critically ill Allo-SCT patients as traditional instruments are of limited value in this setting.

Intensive care outcomes in adult hematopoietic stem cell transplantation patients.

Although outcomes of intensive care for patients undergoing hematopoietic stem cell transplantation (HSCT) have improved in the last two decades, the short-term mortality still remains above 50% among allogeneic HSCT patients. Better selection of HSCT patients for intensive care, and consequently reduction of non-beneficial care, may reduce financial costs and alleviate patient suffering. We reviewed the studies on intensive care outcomes of patients undergoing HSCT published since 2000.

Optimal Threshold and Time of Absolute Lymphocyte Count Assessment for Outcome Prediction after Bone Marrow Transplantation.

The recovery pace of absolute lymphocyte count (ALC) is prognostic after hematopoietic stem cell transplantation. Previous studies have evaluated a wide range of ALC cutoffs and time points for predicting outcomes. We aimed to determine the optimal ALC value for outcome prediction after bone marrow transplantation (BMT).

"No donor"? Consider a haploidentical transplant.

Haploidentical stem cell transplantation (HaploSCT) is an attractive option for patients requiring a hematopoietic stem cell transplant who do not have an HLA-matched donor, because it is cheaper, can be performed faster, and may extend transplantation to virtually all patients in need. Significant advances have been made in the recent decade with dramatic improvement in treatment outcomes. Historically, overcoming the HLA-incompatibility barrier has been a significant limitation to the expansion of this form of transplant.

Strategies in haploidentical stem cell transplantation in adults.

Unlabelled: Haploidentical related donors are alternative stem cell sources for patients without human leukocyte antigen (HLA)-matched related or unrelated donors. Immediate access to the donor, availability for patients with rare haplotypes, ease of stem cell procurement, and lack of a requirement for a physical cord blood bank or an extensive HLA database render this type of hematopoietic stem cell transplantation particularly attractive despite the high histoincompatibility barrier between the recipient and the haploidentical graft. In this review, we answer the following questions: 1) What are the current transplant strategies used to overcome the histoincompatibility barrier in haploidentical stem cell transplantation and their clinical results? 2) How should we choose the donor when there is more than one available haploidentical donor? 3) How does transplantation from haploidentical donors compare to that from umbilical cord blood?

Conflict Of Interest: None declared.

Hematopoietic cell transplantation-specific comorbidity index predicts inpatient mortality and survival in patients who received allogeneic transplantation admitted to the intensive care unit.

Purpose: To investigate the prognostic value of the Hematopoietic Cell Transplantation-Specific Comorbidity Index (HCT-CI) in patients who received transplantation admitted to the intensive care unit (ICU).

Patients And Methods: We investigated the association of HCT-CI with inpatient mortality and overall survival (OS) among 377 patients who were admitted to the ICU within 100 days of allogeneic stem-cell transplantation (ASCT) at our institution. HCT-CI scores were collapsed into four groups and were evaluated in univariate and multivariate analyses using logistic regression and Cox proportional hazards models.

Comparison of cancer care and outcomes between a public safety-net hospital and a private cancer center.

We compared the cancer outcomes and care-associated service defects between Jackson Memorial Hospital (ABC), a large public safety-net hospital, and Sylvester Comprehensive Cancer Center (XYZ), a private not-for-profit cancer center in patients with stage II-III colorectal cancer (CC) who received adjuvant chemotherapy (AC) and in patients with diffuse large B cell lymphoma (DLBCL). Colorectal cancer patients treated at ABC were more likely to have undergone urgent surgery. While in the CC cohort, three-year overall survival and relapse-free survival rates were significantly higher among patients treated at XYZ compared with those treated at ABC, there was no significant difference between patients treated for DLBCL in the two hospitals.

Zidovudine-based lytic-inducing chemotherapy for Epstein-Barr virus-related lymphomas.

Treatment of Epstein-Barr virus (EBV)-related lymphomas with lytic-inducing agents is an attractive targeted approach for eliminating virus-infected tumor cells. Zidovudine (AZT) is an excellent substrate for EBV-thymidine kinase: it can induce EBV lytic gene expression and apoptosis in primary EBV+ lymphoma cell lines. We hypothesized that the combination of AZT with lytic-inducing chemotherapy agents would be effective in treating EBV+ lymphomas.

Ex vivo T cell-depleted versus unmodified allografts in patients with acute myeloid leukemia in first complete remission.

This study was conducted to retrospectively compare the clinical outcomes after transplantation of T cell-depleted (TCD) and unmodified allografts in patients with acute myeloid leukemia (AML) in first complete remission (CR1). Patients received TCD grafts at Memorial Sloan-Kettering Cancer Center (MSKCC, N = 115) between 2001 and 2010 using the following preparative regimens: hyperfractionated total body irradiation (HFTBI)+thiotepa+fludarabine; HFTBI+thiotepa+cyclophosphamide; or i.v.

Fifty years of melphalan use in hematopoietic stem cell transplantation.

Melphalan remains the most widely used agent in preparative regimens for hematopoietic stem cell transplantation (SCT). From its initial discovery more than 50 years ago, it has been gradually incorporated in the conditioning regimens for both autologous and allogeneic transplantations because of its myeloablative properties and broad antitumor effects as a DNA alkylating agent. Melphalan remains the mainstay conditioning for multiple myeloma and lymphomas, and it has been used successfully in preparative regimens of a variety of other hematological and nonhematological malignancies.

Improved early outcomes using a T cell replete graft compared with T cell depleted haploidentical hematopoietic stem cell transplantation.

Haploidentical stem cell transplantation (SCT) has been generally performed using a T cell depleted (TCD) graft; however, a high rate of nonrelapse mortality (NRM) has been reported, particularly in adult patients. We hypothesized that using a T cell replete (TCR) graft followed by effective posttransplantation immunosuppressive therapy would reduce NRM and improve outcomes. We analyzed 65 consecutive adult patients with hematologic malignancies who received TCR (N = 32) or TCD (N = 33) haploidentical transplants.

Outcome of patients with relapsed/refractory acquired immune deficiency syndrome-related lymphoma diagnosed 1999-2008 and treated with curative intent in the AIDS Malignancy Consortium.

No comparative studies exist for relapsed/refractory (rel/rfr) acquired immune deficiency syndrome (AIDS)-related lymphoma (ARL). To determine practices over the last decade and to assess the outcomes of salvage chemotherapy with curative intent and autologous stem cell transplant (ASCT), we retrospectively evaluated treatment outcomes in patients with rel/rfr ARL who were treated in 13 national AIDS Malignancy Consortium (AMC) sites between 1999 and 2008 (n = 88). The most commonly used second-line therapies were ICE (ifosfamide/carboplatin/etoposide, n = 34), dose adjusted EPOCH (etoposide/prednisone/vincristine/cyclophosphamide/doxorubicin, n = 17) and ESHAP (etoposide/methylprednisolone/cytarabine/cisplatin, n = 11).

Vitamin D receptor upregulation in alloreactive human T cells.

Vitamin D deficiency is adversely associated with diseases characterized by inflammation. The combination of the high incidence of vitamin D deficiency in patients undergoing allogeneic stem cell transplants (SCT) and the potential role of vitamin D deficiency in influencing graft-versus-host disease led us to further characterize the expression of VDR on alloreactive T cells. We hypothesized that vitamin D receptor expression may directly regulate alloreactive T cell responses.

Preoperative docetaxel/cisplatin/5-fluorouracil chemotherapy in patients with locally advanced gastro-esophageal adenocarcinoma.

Perioperative chemotherapy plus surgery improves survival compared to surgery alone in GE junctional (GEJ) and gastric adenocarcinomas. The docetaxel/cisplatin/5-fluorouracil (DCF) combination is superior to CF in patients with metastatic gastric cancer. We retrospectively evaluated the safety and efficacy of preoperative DCF chemotherapy in patients with locally advanced gastric and GEJ cancer.

Progress in haploidentical stem cell transplantation.

Haploidentical stem cell transplantation is an attractive form of transplantation because of the immediate donor availability, ease of stem cell procurement, and the possibility to further collect donor cells for cellular therapy. Historically, maintaining T cells in the graft has been associated with very high rates of graft-versus-host-disease (GVHD), whereas T cell-depleted haploidentical transplantation has been limited by a higher incidence of graft rejection and nonrelapse mortality related to infectious complications as a result of delayed immune reconstitution posttransplantation. Recent approaches have attempted to eliminate the alloreactive T cells to prevent GVHD posttransplantation.

Treatment of FLT3-ITD-positive acute myeloid leukemia relapsing after allogeneic stem cell transplantation with sorafenib.

Patients with acute myeloid leukemia (AML) and internal tandem duplication of FMS-like tyrosine kinase receptor-3 gene (FLT3-ITD) mutation have poor prognoses and are often treated with allogeneic hematopoietic stem cell transplantation (HSCT). Sorafenib, an inhibitor of multiple kinases including FLT3, has shown promising activity in FLT3-ITD-positive AML. We treated 16 patients with FLT3-ITD-positive AML who relapsed after HSCT with sorafenib alone (n = 8) or in combination with cytotoxic chemotherapy (n = 8).

Does delay of adjuvant chemotherapy impact survival in patients with resected stage II and III colon adenocarcinoma?

Background: It is unclear whether delays in commencing adjuvant chemotherapy after surgical resection of colon adenocarcinoma adversely impact survival.

Methods: Patients with stage II-III colon adenocarcinoma who received adjuvant chemotherapy at 2 centers were identified through the institutional tumor registry. Time to adjuvant chemotherapy, overall survival (OS), and relapse-free survival (RFS) were calculated from the day of surgery.

Simultaneous measurement of ERα, HER2, and phosphoERK1/2 in breast cancer cell lines by flow cytometry.

The activation of human epidermal growth factor receptor-2 (HER2) results in the activation of the mitogen-activated protein kinase (MAPK) cascade that may lead to the resistance to anti-estrogen therapy in estrogen receptor (ERα) expressing breast cancer by means of phosphorylation of ERα in the N-terminal region by phosphorylated extracellular signal-regulated kinase 1/2 (pERK1/2) and by means of decreasing ERα expression. Immunohistochemistry is the most widely used technique for the detection of ERα and HER2 in breast cancer specimens, however, is inadequate in its ability to assess the relationship between ERα, HER2, and MAPK cascade at the single cell level. To clear this major hurdle, we devised a novel flow cytometric method to quantify the expression of ERα, HER2, and the activation of MAPK cascade simultaneously in single cells.

High-dose glucocorticoids improve renal failure reversibility in patients with newly diagnosed multiple myeloma.

One-fifth of the newly diagnosed multiple myeloma (MM) patients present with renal failure (RF) [1-3]. Glucocorticoids (GCs) may improve RF in MM by (1) rapid reduction of paraprotein production, (2) lessening inflammation and fibrosis in renal parenchyma, and (3) decreasing serum calcium level. We hypothesized that lower dose GCs may be less effective in restoring renal function and retrospectively compared the RF reversibility between the newly diagnosed MM patients who were treated with GCs equivalent to ≥160 mg DX over 4 days (high-dose GC group, n = 16) versus those who were treated with <160 mg (low-dose/no GC group, n = 8).

Advances in haploidentical stem cell transplantation.

Hematopoietic stem cell transplantation from haploidentical donors is an attractive method of transplantation due to the immediate donor availability, ease of stem cell procurement and the possibility to collect additional donor cells for cellular therapy, if needed. Historically, maintaining T-cells in the graft has been associated with very high rates of graft-versus-host disease, while T-cell depleted haploidentical transplantation has been limited by a higher incidence of graft rejection and delayed immune reconstitution post-transplant. Recent approaches attempt to maintain the T-cells in the graft while effectively preventing the development of graft-versus-host disease post-transplant.

Primary ocular adnexal mucosa-associated lymphoid tissue lymphoma (MALT): single institution experience in a large cohort of patients.

Extranodal marginal zone B-cell lymphoma is the most common orbital tumour. We conducted a retrospective analysis to examine: (i) the impact of initial presentation and staging on outcome and (ii) response to various treatment modalities and the effect of the latter on recurrence. Ninety patients with primary ocular adnexal marginal zone lymphoma (POAML) diagnosed at our institution between 1984 and 2009 were studied.
