Efficacy and Safety of Daratumumab in Intermediate/High-risk Smoldering Multiple Myeloma: Final Analysis of CENTAURUS.

Early intervention of smoldering multiple myeloma (SMM) may delay progression to multiple myeloma. Here, we present the final analysis of the phase 2 CENTAURUS study (NCT02316106). In total, 123 patients with intermediate/high-risk SMM were randomized to intravenous daratumumab 16 mg/kg following a Long intense (n = 41), Intermediate (n = 41), or Short intense (n = 41) dosing schedule.

Daratumumab or Active Monitoring for High-Risk Smoldering Multiple Myeloma.

Background: Daratumumab, an anti-CD38 monoclonal antibody, has been approved for the treatment of multiple myeloma. Data are needed regarding the use of daratumumab for high-risk smoldering multiple myeloma, a precursor disease of active multiple myeloma for which no treatments have been approved.

Methods: In this phase 3 trial, we randomly assigned patients with high-risk smoldering multiple myeloma to receive either subcutaneous daratumumab monotherapy or active monitoring.

Adolescent Epstein-Barr Virus Hepatitis Without Typical Mononucleosis Symptoms and Gilbert's Syndrome: A Case Report.

Epstein-Barr virus (EBV) is one of the most common infections worldwide that presents with a multitude of symptoms such as lymphadenopathy, fever, and malaise and has associations with Hodgkin's lymphoma. EBV can cause elevations in transaminase values and hyperbilirubinemia; however, EBV will rarely cause hepatitis with cholestatic features. Here we report a case of a 15-year-old male with a past medical history of potential Gilbert's syndrome who presented with jaundice, scleral icterus, mild abdominal pain, and low-grade fever.

Mutations that prevent phosphorylation of the BMP4 prodomain impair proteolytic maturation of homodimers leading to early lethality in mice.

Bone morphogenetic protein4 (BMP4) plays numerous roles during embryogenesis and can signal either as a homodimer, or as a more active BMP4/7 heterodimer. BMPs are generated as inactive precursor proteins that dimerize and are cleaved to generate the bioactive ligand and inactive prodomain fragments. In humans, heterozygous mutations within the prodomain of BMP4 are associated with birth defects.

Effects of hypothermia and hypoxia on cytochrome P450-mediated drug metabolism in neonatal Göttingen minipigs.

Asphyxiated neonates often undergo therapeutic hypothermia (TH) to reduce morbidity and mortality. As perinatal asphyxia and TH impact neonatal physiology, this could also influence enzyme functionality. Therefore, this study aimed to unravel the impact of age, hypothermia and hypoxia on porcine hepatic cytochrome P450 (CYP) gene expression, protein abundance and activity.

Daratumumab in pediatric relapsed/refractory acute lymphoblastic leukemia or lymphoblastic lymphoma: the DELPHINUS study.

Patients with relapsed/refractory acute lymphoblastic leukemia (ALL) or lymphoblastic lymphoma (LL) have poor outcomes compared with newly diagnosed, treatment-naïve patients. The phase 2, open-label DELPHINUS study evaluated daratumumab (16 mg/kg IV) plus backbone chemotherapy in children with relapsed/refractory B-cell ALL (n = 7) after ≥2 relapses, and children and young adults with T-cell ALL (children, n = 24; young adults, n = 5) or LL (n = 10) after first relapse. The primary end point was complete response (CR) in the B-cell ALL (end of cycle 2) and T-cell ALL (end of cycle 1) cohorts, after which patients could proceed off study to allogeneic hematopoietic stem cell transplant (HSCT).

Physical Treatments and Therapies for Androgenetic Alopecia.

Androgenetic alopecia, the most common cause of hair loss affecting both men and women, is typically treated using pharmaceutical options, such as minoxidil and finasteride. While these medications work for many individuals, they are not suitable options for all. To date, the only non-pharmaceutical option that the United States Food and Drug Administration has cleared as a treatment for androgenetic alopecia is low-level laser therapy (LLLT).

Neurological manifestations in dogs with acute leukemia.

Canine acute leukemia is a rare hematopoietic neoplasm. Neurological abnormalities have been frequently reported in dogs with acute leukemia (AL). However, the description of the presentation and findings are limited.

A Case of Secondary Autoimmune Hemolytic Anemia Successfully Treated With Rituximab.

Secondary cold agglutinin autoimmune hemolytic anemia (AIHA) occurs most commonly due to infectious causes like and, more rarely, Epstein-Barr virus(EBV). Here we present a case of a 69-year-old female presenting with generalized weakness, who was found to have cold agglutinin hemolytic anemia. She unfortunately experienced some of the most severe complications of the disease including encephalopathy, hypoxia, and dry necrosis of peripheral extremities.

Among-species variation in six decades of changing migration timings explained through ecology, life-history and local migratory abundance.

Species exploiting seasonal environments must alter timings of key life-history events in response to large-scale climatic changes in order to maintain trophic synchrony with required resources. Yet, substantial among-species variation in long-term phenological changes has been observed. Advancing from simply describing such variation towards predicting future phenological responses requires studies that rigorously quantify and explain variation in the direction and magnitude of changing timings across diverse species in relation to key ecological and life-history variables.

Short-term fluctuating and long-term divergent selection on sympatric Monkeyflowers: insights from decade-spanning reciprocal transplants.

Sympatric species are often locally adapted to distinct microhabitats. However, temporal variation may cause local maladaptation and species boundary breakdown, especially during extreme climatic events leading to episodic selection. Repeated reciprocal transplants can reveal the interplay between short and long-term patterns of natural selection.

IgE-Mediated Sensitization to Blo t 21 and Blo t 5 Is Associated With Asthma in the Tropics: A Case-Control Study.

Background And Objective: Sensitization to Blomia tropicalis is associated with asthma in various tropical and subtropical countries; however, information about the specific molecular components associated with this disease is scarce. Using molecular diagnosis, we sought to identify B tropicalis allergens associated with asthma in Colombia.

Methods: Specific IgE (sIgE) to 8 B tropicalis recombinant allergens (Blo t 2, 5, 7, 8, 10, 12, 13, and 21) was determined using an in-house ELISA system in asthma patients (n=272) and controls (n=298) recruited in a national prevalence study performed in several Colombian cities (Barranquilla, Bogotá, Medellín, Cali, and San Andrés).

Impact of a 6-12-h delay between ileocolic intussusception diagnostic US and fluoroscopic reduction on patients' outcomes.

Background: Image-guided reduction of intussusception is considered a radiologic urgency requiring 24-h radiologist and technologist availability.

Objective: To assess whether a delay of 6-12 h between US diagnosis and fluoroscopic reduction of ileocolic intussusception affects the success frequency of fluoroscopic reduction.

Materials And Methods: Retrospective review of 0-5-year-olds undergoing fluoroscopic reduction for ileocolic intussusception from 2013 to 2023.

Quality and Diagnosis on the Lateral View of Pediatric Upper Gastro-Intestinal Series.

Background: The standard imaging technique for the diagnosis of intestinal malrotation remains the upper gastro-intestinal series (UGIS). The lateral view is promoted as important for making a diagnosis. For this, the lateral view should be of adequate quality, and radiologists must know the normal appearance as well as the appearance of duodenal variants, as misdiagnosis may lead to unnecessary surgery.

Community-driven governance of FAIRness assessment: an open issue, an open discussion.

Although FAIR Research Data Principles are targeted at and implemented by different communities, research disciplines, and research stakeholders (data stewards, curators, etc.), there is no conclusive way to determine the level of FAIRness intended or required to make research artefacts (including, but not limited to, research data) Findable, Accessible, Interoperable, and Reusable. The FAIR Principles cover all types of digital objects, metadata, and infrastructures.

Impact of hydrocolloid dressings in the prevention of pressure ulcers in high-risk patients: a randomized controlled trial (PENFUP).

It is uncertain whether hydrocolloid dressings, a more costly intervention than offering standard care with petrolatum, is superior to prevent pressure ulcers among hospitalized high-risk adults. Randomized, parallel-group, open-label, superiority trial with an active control group, blinded for investigators, event validators, and analysts (December 1, 2015 to December 12, 2017). Eligible patients were ≥ 18 years of age with intact skin judged as high-risk for skin ulcers (Braden scale), admitted to surgical or medical wards of two tertiary-level hospitals.

Imaging Stewardship: Triage for Neuroradiology MR During Limited-Resource Hours.

Objectives: To decrease call burden on pediatric neuroradiologists, we developed guidelines for appropriate use of MR overnight. These guidelines were implemented using triage by in-house generalist pediatric radiologists. Process measures and balancing measures were assessed during implementation.

The Effect of Habitat on Insect Movements: Experimental Evidence from Wild-Caught Butterflies.

There is broad evidence that the main driver of the ongoing biodiversity crisis is land-use change, which reduces and fragments habitats. The consequence of habitat fragmentation on behavioural responses of fitness-related traits in insects have been so far understudied. In herbivorous insects, oviposition-related behaviours determine access to larval food, and the fate of the next generation.

Relationship between magnetic resonance imaging findings and histological grade in spinal peripheral nerve sheath tumors in dogs.

Background: Peripheral nerve sheath tumors (PNSTs) are a group of neoplasms originating from Schwann cells or pluripotent cell of the neural crest. Therapeutic options and prognosis are influenced by their degree of malignancy and location.

Hypothesis/objectives: Identify magnetic resonance imaging (MRI) features predictive of PNST histologic grade.

The Use of 2-Octylcyanoacrylate Dressing in Reducing the Risk of Superficial Surgical Site Infections in Colorectal Stoma Surgery: A Retrospective Cohort Study.

Background: Superficial surgical site infection (SSI) is a common morbidity following bowel resection surgery involving stoma formation with clinical and financial implications. The study aimed to evaluate the role of topical skin adhesive, 2-octylcyanoacrylate (Dermabond®) (2-OCA) in reducing wound infections following colorectal stoma surgery.

Methods: We performed a retrospective, single-centre, cohort study using clinical notes.

Gauging treatment impact: The development of exposure variables in a large-scale evaluation study.

While guidance on how to design rigorous evaluation studies abounds, prescriptive guidance on how to include critical process and context measures through the construction of exposure variables is lacking. Capturing nuanced intervention dosage information within a large-scale evaluation is particularly complex. The Building Infrastructure Leading to Diversity (BUILD) initiative is part of the Diversity Program Consortium, which is funded by the National Institutes of Health.

Evaluation of the Cerebrospinal Fluid Flow Dynamics with Microvascular Imaging Ultrasound in Infants.

Purpose: Microvascular imaging ultrasound (MVI) can detect slow blood flow in small-caliber cerebral vessels. This technology may help assess flow in other intracranial structures, such as the ventricular system. In this study, we describe the use of MVI for characterizing intraventricular cerebrospinal fluid (CSF) flow dynamics in infants.

Utility of Cerebral Microvascular Imaging in Infants Undergoing ECMO.

Purpose: Infants who require extracorporeal membrane oxygenation (ECMO) therapy have an increased risk of neurological complications and mortality. Microvascular imaging (MVI) is an advanced Doppler technique that allows high-resolution visualization of microvasculature in the brain. We describe the feasibility and utility of MVI for the evaluation of cerebral microvascular perfusion in patients undergoing ECMO.
