A phase 2 study of frontline pembrolizumab in follicular lymphoma.

Background: The tumor microenvironment (TME), including infiltrating T-cells, is thought to play a major role in the pathogenesis and prognosis of follicular lymphoma (FL) and may contribute to its widely varied disease course. We hypothesized that programmed death-1 inhibition may be most effective in untreated, immunocompetent FL patients. Thus, we developed a phase 2 study to evaluate the efficacy of pembrolizumab as the initial treatment for indolent B-cell lymphoma.

Rising to the Top: How Immune-Checkpoint Inhibitors are Changing the Landscape of Treatment for Classic Hodgkin Lymphoma.

Immune checkpoint inhibitors have transformed the future management of classic Hodgkin lymphoma (CHL) in the frontline and salvage settings. Both nivolumab and pembrolizumab have high efficacy in CHL allowing for reduction of chemotherapy and possibly the use of radiotherapy based on short-term follow-up. In this review article, we highlight recent trials enrolling patients with relapse and refractory classic Hodgkin lymphoma receiving monotherapy with PD-1 inhibitors as well as PD-1 and chemotherapy regimens.

Measuring complex SFG: Characterizing a phase reference.

Reactions and interactions at interfaces play pivotal roles in processes ranging from atmospheric aerosols influencing climate to battery electrodes determining charge-discharge rates to defects in catalysts controlling the fate of reactants to the outcome of biological processes at membrane interfaces. Tools to probe these surfaces at the atomic-molecular level are thus critical. Chief among non-invasive probes is the vibrational spectroscopy sum frequency generation (SFG).

The Scottish Hepatology Access Research Partnership (SHARP) improving access to liver services throughout Scotland.

Background And Aims: Scotland has the highest rate of deaths from chronic liver disease (CLD) in the UK. Socioeconomic and geographic isolation represent significant challenges to delivery of care. The multidisciplinary Scottish Hepatology Access Research Partnership (SHARP) aimed to identify and break down barriers to diagnosing and treating liver disease in Scotland.

Has PD-1 blockade changed the standard of care for cHL?

The treatment paradigm for classic Hodgkin lymphoma (CHL) continues to evolve, particularly in light of the incorporation of programmed cell death protein 1 (PD-1) inhibitors into a variety of therapeutic settings. PD-1 inhibitors have demonstrated high efficacy and a favorable toxicity profile when added to a doxorubicin, vinblastine, dacarbazine chemotherapy backbone in patients with untreated CHL. PD-1 inhibitors are also effective treatment options in the relapsed/refractory setting.

Investigating child-facing practitioners' understanding of adversity and its impact on children's development and service provision.

Adversity during childhood is a common risk factor for poorer outcomes across physical, mental, and social health. Despite growing evidence and policy around preventing adversity and its sequalae, the incidence of adversity in childhood remains high. Child-facing practitioners (CfPs) may be well-placed to identify adversity and address its impact on children.

Clinical Relevance of Intensive Laboratory Monitoring With Standard Venetoclax Ramp-Up for Chronic Lymphocytic Leukemia: A Real-World Experience.

Purpose: Venetoclax is the standard of care for chronic lymphocytic leukemia (CLL)/small lymphocytic lymphoma (SLL) but requires intensive monitoring for optimal safety. Clinical relevance of intensive monitoring in practice is unknown, especially for patients with low or intermediate risk for tumor lysis syndrome (TLS).

Patients And Methods: A retrospective review was conducted to determine clinical significance of monitoring for TLS during standard ramp-up for patients with CLL/SLL.

Obesity and leptin in breast cancer angiogenesis.

At the time of breast cancer diagnosis, most patients meet the diagnostic criteria to be classified as obese or overweight. This can significantly impact patient outcome: breast cancer patients with obesity (body mass index > 30) have a poorer prognosis compared to patients with a lean BMI. Obesity is associated with hyperleptinemia, and leptin is a well-established driver of metastasis in breast cancer.

Eyedealistic Vision: Optimizing Oxygenation to Reduce Severe Retinopathy of Prematurity in the Neonatal Intensive Care Unit.

Background: Rates of severe retinopathy of prematurity (ROP) continue to rise globally despite advances in healthcare. Differences in practices related to optimizing oxygenation is among key factors that increase the risk of severe ROP. A recent increase in severe ROP rates at 2 local neonatal intensive care units (NICUs) prompted further investigation into potential preventative practices.

Characterizing the relationship between social determinants of health and risk of albuminuria among children with type 1 diabetes.

In a cohort of 2303 children with type 1 diabetes (T1D), we found that non-English speaking status (HR 2.82, 95% CI 1.54-5.

Accuracy of Non-Invasive Imaging Techniques for the Diagnosis of MASH in Patients With MASLD: A Systematic Review.

Background And Aims: Metabolic dysfunction-associated steatotic liver disease (MASLD) is a growing public health problem. The secondary stage in MASLD is steatohepatitis (MASH), the co-existence of steatosis and inflammation, a leading cause of progression to fibrosis and mortality. MASH resolution alone improves survival.

Analysis of CNS autoimmunity in genetically diverse mice reveals unique phenotypes and mechanisms.

Multiple sclerosis (MS) is a complex disease with significant heterogeneity in disease course and progression. Genetic studies have identified numerous loci associated with MS risk, but the genetic basis of disease progression remains elusive. To address this, we leveraged the Collaborative Cross (CC), a genetically diverse mouse strain panel, and experimental autoimmune encephalomyelitis (EAE).

Critical tasks and errors associated with intercostal chest drain insertion.

Introduction: To describe critical tasks and errors associated with intercostal chest drain insertion, in order to develop enhanced procedural guidelines for task performance and training.

Methods: Expert emergency medicine physicians participated in a three-phased study. First, hierarchical task analyses was used to identify tasks, sub-tasks, and the sequence of tasks.

Antegrade persufflation of porcine kidneys improves renal function after warm ischemia.

Introduction: Transplantation of kidneys from expanded criteria donors (ECD), including after circulatory death (DCD), is associated with a higher risk of adverse events compared to kidneys from standard criteria donors. In previous studies, improvements in renal transplant outcomes have been seen when kidneys were perfused with gaseous oxygen during preservation (persufflation, PSF). In the present study, we assessed ex-vivo renal function from a Diffusion Contrast Enhanced (DCE)-MRI estimation of glomerular filtration rate (eGFR); and metabolic sufficiency from whole-organ oxygen consumption (WOOCR) and lactate production rates.

Discovery of Isomerization Intermediates in CdS Magic-Size Clusters.

Isomerization, the process by which a molecule is coherently transformed into another molecule with the same molecular formula but a different atomic structure, is an important and well-known phenomenon of organic chemistry, but has only recently been observed for inorganic nanoclusters. Previously, CdS nanoclusters were found to isomerize between two end point structures rapidly and reversibly (the α-phase and β-phase), mediated by hydroxyl groups on the surface. This observation raised many significant structural and pathway questions.

Programmed intermittent bolus versus continuous infusion for catheter-based erector spinae plane block on quality of recovery in thoracoscopic surgery: a single-centre randomised controlled trial.

Background: Regional anaesthesia techniques, including the erector spinae fascial plane (ESP) block, reduce postoperative pain after video-assisted thoracoscopic surgery (VATS). Fascial plane blocks rely on spread of local anaesthetic between muscle layers, and thus, intermittent boluses might increase their clinical effectiveness. We tested the hypothesis that postoperative ESP analgesia with a programmed intermittent bolus (PIB) regimen is better than a continuous infusion (CI) regimen in terms of quality of recovery after VATS.

Proof-of-concept study: Remote capillary blood collection for hCG analysis in early pregnancy.

Introduction: Capillary blood collection, a technique traditionally used in diabetes care, shows promise for many applications including pregnancy monitoring. Serial measurement of serum human Chorionic Gonadotrophin (hCG) is frequently necessary for managing early pregnancy, including molar pregnancy, requiring multiple visits to a maternity hospital for blood collection by venepuncture. This proof-of-concept study aimed to assess the clinical performance and user acceptability of capillary blood samples collected remotely, as an alternative to venous blood for hCG measurement.

Parallel HIV-1 fitness landscapes shape viral dynamics in humans and macaques that develop broadly neutralizing antibodies.

Human immunodeficiency virus (HIV)-1 exhibits remarkable genetic diversity. For this reason, an effective HIV-1 vaccine must elicit antibodies that can neutralize many variants of the virus. While broadly neutralizing antibodies (bnAbs) have been isolated from HIV-1 infected individuals, a general understanding of the virus-antibody coevolutionary processes that lead to their development remains incomplete.

Probing the basis of disease heterogeneity in multiple sclerosis using genetically diverse mice.

Unlabelled: Multiple sclerosis (MS) is a complex disease with significant heterogeneity in disease course and progression. Genetic studies have identified numerous loci associated with MS risk, but the genetic basis of disease progression remains elusive. To address this, we leveraged the Collaborative Cross (CC), a genetically diverse mouse strain panel, and experimental autoimmune encephalomyelitis (EAE).

Dengue NS1 Antibodies Are Associated With Clearance of Viral Nonstructural Protein-1.

Background: Dengue vascular permeability syndrome is the primary cause of death in severe dengue infections. The protective versus potentially pathogenic role of dengue nonstructural protein-1 (NS1) antibodies are not well understood. The main goal of this analysis was to characterize the relationship between free NS1 concentration and NS1 antibody titers in primary and secondary dengue infection to better understand the presence and duration of NS1 antibody complexes in clinical dengue infections.

Targeting Anterior Commissure Involvement with Hyperfractionated Radiotherapy for T1-T2 Squamous Cell Carcinoma of the Glottic Larynx.

Anterior commissure is involved in about 20% of early-stage glottic squamous cell carcinomas (EGSCCs). Treatment outcomes and prognostic factors for EGSCC with anterior commissure involvement (ACI) were evaluated by focusing on hyperfractionated radiotherapy (74.4 Gy in 62 fractions).
