Sluggish Cognitive Tempo (SCT) has been defined by a constellation of caregiver-reported symptoms that includes daydreaming, difficulty initiating and sustaining effort, lethargy, and physical underactivity. These symptoms have been observed in both typically developing children and in some children with Attention-Deficit/Hyperactivity Disorder (ADHD)-especially those with the predominantly inattentive presentation. Symptoms of SCT (typically identified via rating scales) appear separable from DSM inattentive ADHD symptoms, but have also been associated with internalizing symptoms...

We describe the case of a 27-year-old woman with a history of sickle cell trait (SCT) who presented with several months of hematuria and was found to have nutcracker syndrome (NCS). While SCT is a common cause of hematuria resulting from renal papillary necrosis, our patient had concomitant abdominal pain and anemia, prompting further evaluation and the subsequent diagnosis of NCS. Interestingly, the anoxia in the left renal vein from NCS predisposes patients with SCT to sickling. Our case highlights key clinical features of both NCS and SCT and the relationship between the two disease processes...

OBJECTIVE: Clinical trials for multiple myeloma patients using novel agent-based regimens before autologous stem cell transplantation (SCT) have shown improvement in response rates and progression-free survival (PFS), however they have failed to identify a significant overall survival (OS) benefit. The aim of this study was to analyze the potential impact of initial induction on the feasibility and outcome of subsequent treatment lines in a real clinical practice setting. METHODS: Consecutive multiple myeloma patients less than 70 years of age diagnosed between 1999 and 2009 were prospectively registered and classified as having received conventional chemotherapy induction regimens with new agents available at relapse (CC cohort, 89 patients) or as treated with novel agents upfront (NA cohort, 65 patients)...

Spondylocarpotarsal synostosis (SCT) is a skeletal disorder characterized by progressive vertebral, carpal and tarsal fusions, and mild short stature. The majority of affected individuals have an autosomal recessive form of SCT and are homozygous or compound heterozygous for nonsense mutations in the gene that encodes the cytoskeletal protein filamin B (FLNB), but a subset do not have FLNB mutations. Exome sequence analysis of three SCT patients negative for FLNB mutations identified an autosomal dominant form of the disease due to heterozygosity for missense or nonsense mutations in MYH3, which encodes embryonic myosin...

We assessed the clinical outcomes of allogeneic hematopoietic stem cell transplantation (SCT) from alternative donors for pediatric patients with hematological malignancies, defining graft-versus-host disease (GVHD)-free, relapse-free survival (GRFS) as a composite endpoint. We also defined chronic GVHD-free, relapse-free survival (cGRFS) as survival without severe chronic GVHD, relapse, or death. The probabilities of 2-year disease-free survival from a human leukocyte antigen (HLA) matched unrelated donor (n = 57), related donor with HLA-1 antigen mismatch in the graft-versus-host direction (1Ag-GvH-MMRD, n = 28), and unrelated umbilical cord blood (n = 35) were 52...

Preclinical studies suggest that stem cell therapy (SCT) may improve sensorimotor recovery after stroke. Upper extremity motor impairment (UEMI) is common after stroke, often entailing substantial disability. To evaluate the feasibility of post-stroke UEMI as a target for SCT, we examined a selected sample of stroke patients potentially suitable for SCT, aiming to assess the frequency and recovery of UEMI, as well as its relation to activity limitations and participation restrictions. Patients aged 20-75 years with first-ever ischemic stroke, and National Institutes of Health Stroke Scale (NIHSS) scores 1-18, underwent brain diffusion-weighted MRI within 4 days of stroke onset (n = 108)...

The WHO classification of testis tumours includes the group of sex cord-stromal tumours. They are divided into several histological types, i.e. Leydig cell (LCT) and Sertoli cell tumours (SCT). Based on the physiological expression of β-catenin in normal testis/Sertoli cells, it was previously shown that SCT can carry a β-catenin mutation, causing a nuclear positivity for β-catenin and cyclin D1. Furthermore, it could be shown that the stabilization of β-catenin in Sertoli cells causes the loss of the Sertoli cell marker SOX9...

BACKGROUND: Hemorrhagic cystitis (HC) is a complication of allogeneic stem cell transplantation (SCT), associated with factors such as BK polyomavirus reactivation, age, conditioning regimen, and presence of graft-versus-host disease (GVHD). The incidence and impact of HC in patients receiving fludarabine (Flu), busulfan (Bu), and anti-thymocyte globulin (ATG) conditioning is unknown. METHODS: We conducted a case-control study of patients undergoing SCT at our center between January 1, 2003 and Dec 31, 2012, to determine the incidence of HC and its effect on patient outcomes including overall survival (OS), relapse, non-relapse mortality, GVHD, and healthcare resource use...

The prognosis for adult acute lymphoblastic leukemia (ALL) patients with central nervous system (CNS) involvement (CNS+) who received allogeneic hematopoietic stem cell transplantation (allo-SCT) remains unclear. We retrospectively compared the outcomes of allo-SCT for patients with CNS involvement and for patients without CNS involvement (CNS-) using a database in Japan. The eligibility criteria for this study were as follows: diagnosis of ALL, aged more than 16 years, allo-SCT between 2005 and 2012, and first SCT...

PURPOSE: Interests have been rapidly growing in the field of radiotherapy to replace CT with magnetic resonance imaging (MRI), due to superior soft tissue contrast offered by MRI and the desire to reduce unnecessary radiation dose. MR-only radiotherapy also simplifies clinical workflow and avoids uncertainties in aligning MR with CT. Methods, however, are needed to derive CT-equivalent representations, often known as synthetic CT (sCT), from patient MR images for the purpose of dose calculation and DRR-based patient positioning...

Adult stem cell transplantation (SCT) patients with graft-versus-host-disease (GVHD) exhibit significant disruptions in gut microbial communities. These changes are associated with higher overall mortality and appear to be driven by specific antibiotic therapies. It is unclear whether pediatric SCT patients who develop GVHD exhibit similar antibiotic-induced gut microbiota community changes. Here, we show that pediatric SCT patients (from Children's Medical Center Dallas, n=8, and Cincinnati Children's Hospital, n=7) who develop GVHD show a significant decline, up to 10-log fold, in gut anti-inflammatory Clostridia (AIC), compared to those without GVHD...

Acetolactate synthase (ALS) is the common target of ALS-inhibiting herbicides, and target-site ALS mutations are the main mechanism of resistance to ALS-inhibiting herbicides. In this study, ALS1 and ALS2 genes with full lengths of 2004bp and 1998bp respectively were cloned in individual plants of susceptible (S) or resistant (R) flixweed (Descurainia sophia L.) populations. Two ALS mutations of Pro-197-Thr and/or Trp-574-Leu were identified in plants of three R biotypes (HB24, HB30 and HB42). In order to investigate the function of ALS isozymes in ALS-inhibiting herbicide resistance, pHB24 (a Pro-197-Thr mutation in ALS1 and a wild type ALS2), pHB42 (a Trp-574-Leu mutation in ALS1 and a wild type ALS2) and pHB30 (a Trp-574-Leu mutation in ALS1 and a Pro-197-Thr mutation in ALS2) subpopulations individually homozygous for different ALS mutations were generated...

OBJECTIVE: To evaluate the effect of dexmedetomidine infusions in patients with advanced malignancies, advanced heart disease, or after stem cell transplantation (SCT), who during end-of-life care had pain and/or agitation unresponsive to conventional therapies. BACKGROUND: Pediatric patients with intractable advanced malignancies, end-stage congenital heart diseases, or after SCT can suffer a great deal during end of life. Pain, drowsiness, fatigue, irritability, and worrying are experienced frequently, considered distressing, and are strongly associated with reductions in health-related quality-of-life scores...

Temperature dependent rate coefficients for the reaction of Cl atom with 1,3-butadiene were measured over the temperature range of 269-363K relative to its reaction with isoprene and 1-pentene. Theoretical calculations were performed for the title reaction using CVT/SCT in combination with CCSD(T)/6-31+G (d,p)//MP2/6-311+G(2df,2p) level of theory, to complement our experimental measurements. The test molecule would survive for one hour in the atmosphere and therefore, it can be considered as a very short lived compound...

A man in his 20s with a history of classical Hodgkin's lymphoma was admitted with fever. His original lymphoma diagnosis was made 3 years prior, when he had presented with lymphadenopathy and a mediastinal mass. He had relapsed disease despite chemotherapy and radiation. As a result, he underwent autologous peripheral blood stem cell transplant (SCT) 6 months prior to current presentation and subsequently allogeneic SCT 2 months prior for added graft vs tumor effect.

The majority of the older population shows signs of radiographic knee osteoarthritis. However, many remain without functional complaints for a long period. This study aims to find early functional changes associated with stages of radiographic knee osteoarthritis. A group of older people without self-reported complaints was divided in 2 groups, knee osteoarthritis (K&L=2-4, N=29) and control (K&L=0-1, N=31). Muscle function was assessed with voluntary and electrically stimulated isometric knee contractions, including a fatigue test...

Allogeneic hematopoietic stem cell transplantation (allo-SCT) is a therapeutic option for relapsed, advanced, and otherwise incurable non-Hodgkin's lymphomas (NHL) suggested by the existence of a graft-versus-lymphoma effect. The main complications are graft-versus-host disease and infections. We performed a retrospective analysis of patients with NHL, who received an allo-SCT between January 1995 and December 2014. The parameters that had an impact on overall survival were age ≤60 years old, chemosensitive disease pre-allo-SCT, and indolent NHL histology...
