Psychoneurologic symptoms commonly reported by adolescents and young adults (AYAs) following hematopoetic stem cell transplantation (HSCT) include anxiety, depression, fatigue, and pain. Complementary and alternative medicine (CAM) appeals to AYAs as a means of coping with these symptoms. One example of CAM is a publicly available illness blog authored by a young adult woman undergoing HSCT.

BACKGROUND: While viral surveillance of cytomegalovirus (CMV), Epstein-Barr virus (EBV), and adenovirus using PCR is routine in patients undergoing hematopoetic stem cell transplant and solid organ transplant, the utility in the nontransplant pediatric leukemia population is unknown. Our institution screens patients with acute lymphoblastic leukemia (ALL) and acute myeloid leukemia (AML) for viral DNAemia by PCR as part of clinical care. PROCEDURE: This retrospective chart review included patients treated for newly diagnosed or relapsed AML or ALL between April 2010 and September 2014...

Causal inference for non-censored response variables, such as binary or quantitative outcomes, is often based on either (1) direct standardization ('G-formula') or (2) inverse probability of treatment assignment weights ('propensity score'). To do causal inference in survival analysis, one needs to address right-censoring, and often, special techniques are required for that purpose. We will show how censoring can be dealt with 'once and for all' by means of so-called pseudo-observations when doing causal inference in survival analysis...

Transparency of the human cornea is necessary for vision. Fuchs Endothelial Corneal Dystrophy (FECD) is a bilateral, heritable degeneration of the corneal endothelium, and a leading indication for corneal transplantation in developed countries. While the early onset, and rarer, form of FECD has been linked to COL8A2 mutations, the more common, late onset form of FECD has genetic mutations linked to only a minority of cases. Epigenetic modifications that occur in FECD are unknown. Here, we report on and compare the DNA methylation landscape of normal human corneal endothelial (CE) tissue and CE from FECD patients using the Illumina Infinium HumanMethylation450 (HM450) DNA methylation array...

Urinary cell-free (cf) DNA holds great potential as a completely noninvasive form of liquid biopsy. Knowledge of the composition of cfDNA by tissue of origin is useful for guiding its clinical uses. We conducted a global survey of urinary cfDNA composition using genomewide bisulfite sequencing. While previous studies focused on detecting cfDNA from a single source at a time, genomewide tissue specific methylation signatures allow us to simultaneously deduce the proportional contribution from each contributing tissue...

Allogeneic hematopoietic stem cell transplantation (allo-HSCT) is a potentially curative treatment option for patients with acute lymphoblastic leukemia (ALL). The curative potential of allo-HSCT for ALL is, in part, due to the graft-vs.-leukemia (GVL) effect, in addition to the intensive conditioning chemo-radiotherapy. However, relapse remains the major cause of treatment failure following allo-HSCT for ALL. In the allo-HSCT setting, testing for genetic markers of hematopoietic chimerism has become a part of the routine diagnostic program...

Allogeneic hematopoetic stem cell transplantation (allo-HSCT) is a standard treatment for leukemia and other hematologic malignancies. The major complication of allo-HSCT is graft-versus-host-disease (GVHD), a progressive inflammatory illness characterized by donor immune cells attacking the organs of the recipient. Current GVHD prevention and treatment strategies use immune suppressive drugs and/or anti-T cell reagents these can lead to increased risk of infections and tumor relapse. Recent research demonstrated that epigallocatechin gallate (EGCG), a component found in green tea leaves at a level of 25-35% at dry weight, may be useful in the inhibition of GVHD due to its immune modulatory, anti-oxidative and anti-angiogenic capacities...

The incidence of life threatening invasive fungal infections in patients with hematological malignancies during intensive chemotherapy or after hematopoetic stem cell transplantation, patients after solid organ transplantation, ICU patients and premature infants is rising. Mortality rates of invasive fungal infections, caused by Aspergillus species or mucormycetes, may reach 100%, in spite of considerable progress in diagnosis, antifungal prophylaxis and therapy. Comprehensive, profound knowledge of specific diagnostic and current treatment algorithms is essential to improve the prognosis of patients suffering from systemic fungal infections; this article encompasses recent developments in the field of antifungal treatment...

We present the case of a 51-year-old man with acute myeloid leukemia who developed fevers with a skin lesion following the first cycle of induction chemotherapy. Skin biopsy showed evidence of invasive fungal infection. Cultures remained negative, but polymerase chain reaction on tissue detected Rhizopus oryzae complex. The patient was started on liposomal amphotericin B and underwent surgical debridement. He was switched to posaconazole, with plans for allogeneic hematopoetic stem cell transplant in the future...

BACKGROUND: Absent T-cell immunity resulting in life-threatening infections provides a clear rationale for hematopoetic stem cell transplantation (HSCT) in patients with severe combined immunodeficiency (SCID). Combined immunodeficiencies (CIDs) and "atypical" SCID show reduced, not absent T-cell immunity. If associated with infections or autoimmunity, they represent profound combined immunodeficiency (P-CID), for which outcome data are insufficient for unambiguous early transplant decisions...

Hematopoetic stem cell transplantation (HSCT) is an established therapeutic option for both malignant and nonmalignant indications, whose incidence has continued to increase in recent years. Because of its lower cost and lack of radiation exposure, ultrasound examination is often the first-line imaging modality in evaluating patients both before and after HSCT. It is important for radiologists to be aware of sonographic manifestations of the complications that may arise from HSCT. In this study, we will review the basics of HSCT, the role of imaging, and ultrasound examination findings in common and uncommon complications arising from HSCT...

Immunosuppression of various origins is associated with an increased risk of infection; therefore the prevention of infectious diseases by vaccination is especially important in immunocompromised patients. However, the response to vaccinations is often reduced in these risk groups and the application of live vaccines is contraindicated during immunosuppression.In the following expert statement, recommendations for vaccination were created on the basis of current evidence and theoretical/immunological considerations...

OBJECTIVE: A novel approach to regulate obesity-associated adipose inflammation may be through metabolic reprogramming of macrophages (MΦs). Broadly speaking, MΦs dependent on glucose are pro-inflammatory, classically activated MΦs (CAM), which contribute to adipose inflammation and insulin resistance. In contrast, MΦs that primarily metabolize fatty acids are alternatively activated MΦs (AAM) and maintain tissue insulin sensitivity. In actuality, there is much flexibility and overlap in the CAM-AAM spectrum in vivo dependent upon various stimuli in the microenvironment...

Intravenous (IV) busulfan doses are often personalized to a concentration at steady state (Css) using the patient's clearance, which is estimated with therapeutic drug monitoring. We sought to identify biomarkers of IV busulfan clearance using a targeted pharmacometabonomics approach. A total of 200 metabolites were quantitated in 106 plasma samples, each obtained before IV busulfan administration in hematopoietic cell transplant (HCT) recipients. Both univariate linear regression with false discovery rate (FDR) and pathway enrichment analyses using the Global test were performed...

Sfrp2 is overexpressed in stromal cells which maintain hematopoietic stem cells (HSCs) during in vitro culture. We here showed, that coculture of hematopoetic cells with stromal cells with reduced expression of Sfrp2 increases the number lineage-negative Kit(+) Sca-1(+) (LSK) and progenitor cells in vitro. The LSK cells from these cocultures showed activation of canonical Wnt signaling, higher levels of Ki-67, BrdU incorporation, and the number of γH2A.X positive foci. Total repopulating activity of these cultures was, however, diminished, indicating loss of HSC...
