Loncastuximab tesirine with rituximab in patients with relapsed or refractory follicular lymphoma: a single-centre, single-arm, phase 2 trial.

Background: Preliminary data suggest promising activity of loncastuximab tesirine in follicular lymphoma, and synergistic activity between rituximab-induced cytotoxicity and loncastuximab tesirine. In this study, we evaluated loncastuximab tesirine combined with rituximab for second-line and later treatment of follicular lymphoma.

Methods: We did a single-arm, investigator-initiated, phase 2 trial at Sylvester Comprehensive Cancer Center in Miami, FL, USA.

Mutagenic impact and evolutionary influence of radiotherapy in hematologic malignancies.

Ionizing radiotherapy (RT) is a widely used palliative and curative treatment strategy for malignancies. In solid tumors, RT-induced double strand breaks lead to the accumulation of indels, and their repair by non-homologous end-joining has been linked to the ID8 mutational signature in resistant cells. However, the extent of RT-induced DNA damage in hematologic malignancies and its impact on their evolution and interplay with commonly used chemotherapies has not yet been explored.

The cyclin-G associated kinase (GAK) is a novel mitotic kinase and therapeutic target in diffuse large B-cell lymphoma.

Diffuse large B cell lymphoma (DLBCL) is an aggressive non-Hodgkin lymphoma and the most frequently diagnosed hematologic malignancy in the United States. DLBCL exhibits significant molecular and clinical heterogeneity, and at least a third of patients are left uncured with standard frontline chemoimmunotherapy. As such, there is a critical need to identify novel targeted therapies to improve outcomes.

NRF2 translation block by inhibition of cap-dependent initiation sensitizes lymphoma cells to ferroptosis and CAR-T immunotherapy.

Cancers coopt stress-response pathways to drive oncogenesis, dodge immune surveillance, and resist cytotoxic therapies. Several of these provide protection from ferroptosis, iron-mediated oxidative cell death. Here, we found dramatic sensitization to ferroptosis upon disruption of cap-dependent translation in diffuse large B-cell lymphoma (DLBCL).

Comorbid ADHD and Pediatric Sickle Cell Disease: Prevalence and Risk Factors.

Sickle cell disease (SCD) is a genetic blood condition that places youth at increased risk for deficits in complex attention suggestive of increased risk for Attention-Deficit/Hyperactivity Disorder (ADHD). We used systematic screening to assess the prevalence of ADHD in a clinic-based sample of youth with SCD and explored factors related to ADHD. Caregivers of 107 children with SCD (ages 7-11 years) completed routine psychosocial screening which included inattentive symptoms of ADHD.

Button shear testing for adhesion measurements of 2D materials.

Two-dimensional (2D) materials are considered for numerous applications in microelectronics, although several challenges remain when integrating them into functional devices. Weak adhesion is one of them, caused by their chemical inertness. Quantifying the adhesion of 2D materials on three-dimensional surfaces is, therefore, an essential step toward reliable 2D device integration.

Functional and Radiologic Outcomes of Degenerative Versus Traumatic Full-Thickness Rotator Cuff Tears Involving the Supraspinatus Tendon.

Background: Arthroscopic rotator cuff repair (ARCR) is among the most commonly performed orthopaedic procedures. Several factors-including age, sex, and tear severity-have been identified as predictors for outcome after repair. The influence of the tear etiology on functional and structural outcome remains controversial.

Current-Limited Conductive Atomic Force Microscopy.

Conductive atomic force microscopy (CAFM) has become the preferred tool of many companies and academics to analyze the electronic properties of materials and devices at the nanoscale. This technique scans the surface of a sample using an ultrasharp conductive nanoprobe so that the contact area between them is very small (<100 nm) and it can measure the properties of the sample with a very high lateral resolution. However, measuring relatively low currents (∼1 nA) in such small areas produces high current densities (∼1000 A/cm), which almost always results in fast nanoprobe degradation.

Functional drivers of resistance to anti-CD19 CAR-T cell therapy in diffuse large B cell lymphoma.

Chimeric antigen receptor T-cell therapy targeting CD19 (CAR-19) promotes impressive durable remissions for relapsed or refractory (rel/ref) large B-cell lymphoma (LBCL) patients with historically poor prognoses. Despite this, over half of patients still fail to respond or eventually progress. Studies to reveal mechanisms of resistance have examined host clinical parameters, CAR-19 product composition, and tumor microenvironment (TME) alterations, while a relative paucity of studies has analyzed contributions by genomic alterations in tumor cells.

Implementation of Two Developmental Screening Programs in Sickle Cell Disease Specialty Care.

Objective: Developmental screening is a critical component of care for children with sickle cell disease (SCD), who are at elevated risk for neurodevelopmental disorders. This report describes the implementation of two related developmental screening programs implemented in different SCD specialty care settings with the purpose of describing screening protocols, outcomes, and lessons learned.

Methods: Program One reviewed medical records for 201 children with SCD screened at ages 2 and 4 years.

Fatigue, Stress Appraisal, and Emotional Functioning Among Youth With Sickle Cell Disease: A Daily Diary Study.

Objective: The aim of this study was to assess how fatigue is related to mood among youth with sickle cell disease (SCD) by evaluating if the cognitive appraisal of stress moderates the impact of fatigue on emotional functioning consistent with the Risk-and-Resistance Model of Chronic Illness.

Methods: Daily diaries assessing fatigue (Numerical Rating Scale), pain intensity (Numerical Rating Scale), mood (Positive and Negative Affect Schedule for Children), and cognitive appraisal of stress (Stress Appraisal Measure for Adolescents) were collected from 25 youth with SCD (ages 11-18 years) for 8 consecutive weeks resulting in 644 daily diaries for analyses.

Results: When measured concurrently, higher fatigue was associated with higher negative mood controlling for pain and prior-night sleep quality.

Solid Platinum Nanoprobes for Highly Reliable Conductive Atomic Force Microscopy.

Conductive atomic force microscopy (CAFM) is a powerful technique to investigate electrical and mechanical properties of materials and devices at the nanoscale. However, its main challenge is the reliability of the probe tips and their interaction with the samples. The most common probe tips used in CAFM studies are made of Si coated with a thin (∼20 nm) film of Pt or Pt-rich alloys (such as Pt/Ir), but this can degrade fast due to high current densities (>10A/cm) and mechanical frictions.

Efficacy of checkpoint inhibition after CAR-T failure in aggressive B-cell lymphomas: outcomes from 15 US institutions.

Checkpoint inhibitor (CPI) therapy with anti-PD-1 antibodies has been associated with mixed outcomes in small cohorts of patients with relapsed aggressive B-cell lymphomas after CAR-T failure. To define CPI therapy efficacy more definitively in this population, we retrospectively evaluated clinical outcomes in a large cohort of 96 patients with aggressive B-cell lymphomas receiving CPI therapy after CAR-T failure across 15 US academic centers. Most patients (53%) had diffuse large B-cell lymphoma, were treated with axicabtagene ciloleucel (53%), relapsed early (≤180 days) after CAR-T (83%), and received pembrolizumab (49%) or nivolumab (43%).

Preschool Pain Management Program for Young Children with Sickle Cell Disease: A Pre-Post Feasibility Study.

Objective: Vaso-occlusive pain crises in sickle cell disease (SCD) often begin in early childhood. We developed an online pain management intervention to teach caregivers of preschool-aged children with SCD behavioral pain management strategies. The feasibility study goals were to examine response to recruitment, barriers to participation, engagement, acceptability and perceived usefulness of the intervention, and suitability of outcome measures.

MATRIX platform to analyze translation machinery remodeling in glioblastoma cells.

Here, we present a protocol using MATRIX (mass spectrometry analysis of active translation factors using ribosome density fractionation and isotopic labeling experiments) platform to investigate changes of the protein synthesis machinery in U87MG glioblastoma cells in response to the rocaglate silvestrol. This protocol describes steps to perform SILAC (stable isotope labeling by amino acids in cell culture), ribosome density fractionation, protein isolation, and mass spectrometry analysis. This approach can be applied to study any adaptive remodeling of protein synthesis machineries.

Normofractionated irradiation and not temozolomide modulates the immunogenic and oncogenic phenotype of human glioblastoma cell lines.

Purpose: Glioblastoma multiforme (GBM) is the most aggressive primary brain tumor, with an overall poor prognosis after diagnosis. Conventional treatment includes resection, chemotherapy with temozolomide (TMZ), and concomitant radiotherapy (RT). The recent success of immunotherapy approaches in other tumor entities, particularly with immune checkpoint inhibitors, could not be clinically transferred to GBM treatment so far.

Sleep and fatigue among youth with sickle cell disease: A daily diary study.

Youth with sickle cell disease (SCD) experience disease effects including vaso-occlusive pain crises, poor sleep quality, and fatigue. The present study examines how sleep quality and pain medications impact fatigue in youth with SCD. Daily diaries assessing pain, fatigue, sleep quality, mood, and use of pain medications from 25 youth with SCD ages 11 to 18 years were collected for eight consecutive weeks.

Investigation of Heater Structures for Thermal Conductivity Measurements of SiO and AlO Thin Films Using the 3-Omega Method.

A well-known method for measuring thermal conductivity is the 3-Omega (3) method. A prerequisite for it is the deposition of a metal heater on top of the sample surface. The known design rules for the heater geometry, however, are not yet sufficient.

Modeling the Remote Associates Test as Retrievals from Semantic Memory.

The Remote Associates Test (RAT) is a word association retrieval task that consists of a series of problems, each with three seemingly unrelated prompt words. The subject is asked to produce a single word that is related to all three prompt words. In this paper, we provide support for a theory in which the RAT assesses a person's ability to retrieve relevant word associations from long-term memory.

Whole-genome sequencing reveals complex genomic features underlying anti-CD19 CAR T-cell treatment failures in lymphoma.

CD19-directed chimeric antigen receptor (CAR-19) T cells are groundbreaking immunotherapies approved for use against large B-cell lymphomas. Although host inflammatory and tumor microenvironmental markers associate with efficacy and resistance, the tumor-intrinsic alterations underlying these phenomena remain undefined. CD19 mutations associate with resistance but are uncommon, and most patients with relapsed disease retain expression of the wild-type receptor, implicating other genomic mechanisms.

Condylar resorption following mandibular advancement or bimaxillary osteotomies: A systematic review of systematic reviews.

Several systematic reviews have been published on the effects of mandibular surgery on condylar remodeling without reaching a consensus. The purpose of this systematic review of systematic reviews was to assess the impact of mandibular advancement or bimaxillary surgeries on condylar resorption. A literature search, using several electronic databases, was carried out by two reviewers independently.

Infants' object interactions are long and complex during everyday joint engagement.

As infants interact with the object world, they generate rich information about object properties and functions. Much of infant learning unfolds in the presence of caregivers, who talk about and act on the objects of infant play. Does mother joint engagement correspond to real-time changes in the complexity and duration of infant object interactions? We observed 38 mothers and their first-born infants (cross-sectional, 13, 18, and 23 months) during 2 h of everyday activity as infants freely navigated their home environments.
