The need for novel influenza vaccines in low- and middle-income countries: A narrative review.

Influenza viruses cause 3-5 million severe cases and 300,000-600,000 deaths worldwide. Most of the disease burden is in Low- and Middle-Income Countries (LMICs) owing to factors such as high population density, infrastructure challenges, poor quality healthcare, lack of consistent recommendations, less prioritization of all high-risk groups, and prevalent use of trivalent influenza vaccines. Although influenza vaccines are effective in reducing the annual influenza disease burden, existing vaccines have several limitations.

An osteopathic assessment of lower extremity somatic dysfunctions in runners.

Context: Runners often experience acute/chronic pain due to pre-existing structural somatic dysfunction and/or acquired various overuse injuries of the lower extremity, specifically affecting the ligaments, tendons, muscles, and bones. Common structural and function dysfunctions include but are not limited to patellofemoral pain syndrome (PFPS), Achilles tendonitis, iliotibial band syndrome (ITBS), ligamentous and muscle tears, muscle sprains/strains, stress fractures, pes planus, plantar fasciitis, and shin splints.

Objectives: The purpose of this study is to assess the correlation between acute and chronic pain, overuse injuries, and observational and palpatory findings upon evaluation to establish common trends of somatic dysfunctions and determine possible etiology of the pain/injury.

Management of Recurrent Vancomycin-resistant Bacteremia With Oritavancin: A Case Report.

Background/aim: Vancomycin-resistant Enterococcus causes significant morbidity, mortality, and excess healthcare costs when compared to vancomycin-susceptible isolates. Patients with hematological malignancies, especially those who undergo hematopoietic stem cell transplantation, are at a particularly high risk for infections with vancomycin-resistant Enterococcus, with mortality ranging from 40-100%. Linezolid and daptomycin are the two most commonly used antibiotics for treatment of vancomycin-resistant enterococcal infections, however, there has been recent emergence of resistance to these drugs as well.

Temporal coherence shapes cortical responses to speech mixtures in a ferret cocktail party.

Perceptual segregation of complex sounds such as speech and music simultaneously emanating from multiple sources is a remarkable ability that is common in humans and other animals alike. Unlike animal physiological experiments with simplified sounds or human investigations with spatially broad imaging techniques, this study combines insights from animal single-unit recordings with segregation of speech-like sound mixtures. Ferrets are trained to attend to a female voice and detect a target word, both in presence and absence of a concurrent equally salient male voice.

A pan-cancer single-cell RNA-seq atlas of intratumoral B cells.

Tumor-infiltrating B cells play a significant role in tumor development, progression, and prognosis, yet a comprehensive classification system is lacking. To address this gap, we present a pan-cancer single-cell RNA sequencing (scRNA-seq) atlas of tumor-infiltrating B and plasma cells across a large sample cohort. We identify key B cell subset signatures, revealing distinct subpopulations and highlighting the heterogeneity and functional diversity of these cells in the tumor microenvironment.

The mesolimbic system and the loss of higher order network features in schizophrenia when learning without reward.

Introduction: Schizophrenia is characterized by a loss of network features between cognition and reward sub-circuits (notably involving the mesolimbic system), and this loss may explain deficits in learning and cognition. Learning in schizophrenia has typically been studied with tasks that include reward related contingencies, but recent theoretical models have argued that a loss of network features should be seen even when learning without reward. We tested this model using a learning paradigm that required participants to learn without reward or feedback.

Using a pan-cancer atlas to investigate tumour associated macrophages as regulators of immunotherapy response.

The paradigm for macrophage characterization has evolved from the simple M1/M2 dichotomy to a more complex model that encompasses the broad spectrum of macrophage phenotypic diversity, due to differences in ontogeny and/or local stimuli. We currently lack an in-depth pan-cancer single cell RNA-seq (scRNAseq) atlas of tumour-associated macrophages (TAMs) that fully captures this complexity. In addition, an increased understanding of macrophage diversity could help to explain the variable responses of cancer patients to immunotherapy.

Temporal Coherence Shapes Cortical Responses to Speech Mixtures in a Ferret Cocktail Party.

Segregation of complex sounds such as speech, music and animal vocalizations as they simultaneously emanate from multiple sources (referred to as the "cocktail party problem") is a remarkable ability that is common in humans and animals alike. The neural underpinnings of this process have been extensively studied behaviorally and physiologically in non-human animals primarily with simplified sounds (tones and noise sequences). In humans, segregation experiments utilizing more complex speech mixtures are common; but physiological experiments have relied on EEG/MEG/ECoG recordings that sample activity from thousands of neurons, often obscuring the detailed processes that give rise to the observed segregation.

Systemic DNA Damage and Repair Activity Vary by Race in Breast Cancer Survivors.

Non-Hispanic Black breast cancer survivors have poorer outcomes and higher mortality rates than White survivors, but systemic biological mechanisms underlying these disparities are unclear. We used circulating leukocytes as a surrogate for measuring systemic mechanisms, which might be different from processes in the target tissue (e.g.

Implementing a Quality Intervention to Improve Confidence in Outpatient Venous Thromboembolism Management.

Introduction: Guidelines recommend that patients with acute venous thromboembolism (VTE) represented by low-risk deep vein thrombosis (DVT) and pulmonary embolism (PE) receive initial treatment at home versus at the hospital, but a large percentage of these patients are not managed at home. This study assessed the effectiveness of a quality intervention on provider knowledge and confidence in evaluating outpatient treatment for patients with VTE in the emergency department (ED).

Methods: A pilot program to overcome obstacles to outpatient VTE treatment in appropriate patients was initiated at Baylor Scott & White Health Temple ED.

Temporal dynamics and genomic programming of plasma cell fates.

Affinity-matured plasma cells (PCs) of varying lifespans are generated through a germinal center (GC) response. The developmental dynamics and genomic programs of antigen-specific PC precursors remain to be elucidated. Here, using a model antigen in mice, we demonstrate biphasic generation of PC precursors, with those generating long-lived bone marrow PCs preferentially produced in the late phase of GC response.

Comparison of insertion characteristics of LMA ProSeal from the front and head-end of the patient: A randomized pilot study.

Background And Aims: LMA ProSeal (PLMA) is a commonly used airway maintenance device in elective procedures and is routinely inserted from the head-end of the patient. It is also used in pre-hospital emergencies where it may not always be possible to access the head-end. This study aims to compare the insertion characteristics of PLMA when inserted while standing, either at the head-end or from the front.

Redefining the Role of Medical Affairs Professionals as Innovators and Leaders in Industry-Led Medical Education.

Medical affairs professionals are pivotal players at the intersection of medical innovation and practice in the pharmaceutical industry. They are uniquely positioned to translate complex medical knowledge into actionable insights for internal and external stakeholders. Industry-led continuing medical education (CME) programs, guided by these professionals, hold the potential to markedly improve clinicians' application of evidence-based medicine (EBM) in clinical settings, thereby elevating patient care outcomes.

Decrypting the multifaceted peripheral neuropathy based on molecular pathology and therapeutics: a comprehensive review.

Context: Peripheral neuropathy (PN) is a multifaceted complication characterized by nerve damage due to oxidative stress, inflammatory mediators, and dysregulated metabolic processes. Early PN manifests as sensory changes that develop progressively in a "stocking and glove" pattern.

Methods And Mechanisms: A thorough review of literature has been done to find the molecular pathology, clinical trials that have been conducted to screen the effects of different drugs, current treatments and novel approaches used in PN therapy.

An immunophenotype-coupled transcriptomic atlas of human hematopoietic progenitors.

Analysis of the human hematopoietic progenitor compartment is being transformed by single-cell multimodal approaches. Cellular indexing of transcriptomes and epitopes by sequencing (CITE-seq) enables coupled surface protein and transcriptome profiling, thereby revealing genomic programs underlying progenitor states. To perform CITE-seq systematically on primary human bone marrow cells, we used titrations with 266 CITE-seq antibodies (antibody-derived tags) and machine learning to optimize a panel of 132 antibodies.

Pre-saccadic shifts of attention in individuals diagnosed with schizophrenia.

Introduction: Pathophysiological theories of schizophrenia (SZ) symptoms posit an abnormality in using predictions to guide behavior. One such prediction is based on imminent movements, via corollary discharge signals (CD) that relay information about planned movement kinematics to sensory brain regions. Empirical evidence suggests a reduced influence of sensorimotor predictions in individuals with SZ within multiple sensory systems, including in the visual system.

Abnormal Oculomotor Corollary Discharge Signaling as a Trans-diagnostic Mechanism of Psychosis.

Background And Hypothesis: Corollary discharge (CD) signals are "copies" of motor signals sent to sensory areas to predict the corresponding input. They are a posited mechanism enabling one to distinguish actions generated by oneself vs external forces. Consequently, altered CD is a hypothesized mechanism for agency disturbances in psychosis.

Stronger tilt aftereffects in individuals diagnosed with schizophrenia spectrum disorders but not bipolar disorder.

An altered use of context and experience to interpret incoming information has been posited to explain schizophrenia symptoms. The visual system can serve as a model system for examining how context and experience guide perception and the neural mechanisms underlying putative alterations. The influence of prior experience on current perception is evident in visual aftereffects, the perception of the "opposite" of a previously viewed stimulus.
