Efficacy and safety of currently approved and lower starting doses of inotuzumab ozogamicin in adult patients with relapsed or refractory acute lymphoblastic leukemia: a phase IV study.

Inotuzumab ozogamicin (InO) is approved for treatment of relapsed/refractory acute lymphoblastic leukemia (R/R ALL). Previous studies reported higher rates of post- hematopoietic stem cell transplant (HSCT) hepatic sinusoidal obstruction syndrome (SOS) in patients receiving InO versus chemotherapy prior to HSCT. It is unknown if a lower InO dose would reduce risk of post-HSCT SOS or if it would impact efficacy.

Chronic fetal hypoxia and antenatal Vitamin C exposure differentially regulate molecular signalling in the lung of female lambs in early adulthood.

Introduction: Chronic fetal hypoxia is commonly associated with fetal growth restriction and can predispose to respiratory disease at birth and in later life. Antenatal antioxidant treatment has been investigated to overcome the effects of oxidative stress to improve respiratory outcomes. We aimed to determine if the effects of chronic fetal hypoxia and antenatal antioxidant administration persist in the lung in early adulthood.

Study Protocol for 'PsilOCD: A Pharmacological Challenge Study Evaluating the Effects of the 5-HT2A Agonist Psilocybin on the Neurocognitive and Clinical Correlates of Compulsivity'.

Background: Obsessive-compulsive disorder (OCD) is a complex condition marked by persistent distressing thoughts and repetitive behaviours. Despite its prevalence, the mechanisms behind OCD remain elusive, and current treatments are limited. This protocol outlines an investigative study for individuals with OCD, exploring the potential of psilocybin to improve key components of cognition implicated in the disorder.

Predicting conversion to psychosis using machine learning: response to Cannon.

Background: We previously reported that machine learning could be used to predict conversion to psychosis in individuals at clinical high risk (CHR) for psychosis with up to 90% accuracy using the North American Prodrome Longitudinal Study-3 (NAPLS-3) dataset. A definitive test of our predictive model that was trained on the NAPLS-3 data, however, requires further support through implementation in an independent dataset. In this report we tested for model generalization using the previous iteration of NAPLS-3, the NAPLS-2, using the identical machine learning algorithms employed in our previous study.

The IclR-family transcriptional regulator XyrR controls flotation, motility, antibiotic production and virulence in sp. ATCC 39006.

The opportunistic pathogen sp. ATCC 39006 (S39006) is a rod-shaped, motile, Gram-negative bacterium that produces a 𝛽-lactam antibiotic (a carbapenem) and a bioactive red-pigmented tripyrrole antibiotic, prodigiosin. It is also the only known enterobacterium that naturally produces intracellular gas vesicles (GVs), enabling cells to float in static water columns.

The mind, brain, and body study: A protocol for examining the effects of the gut-brain-immune axis on internalizing symptoms in youth exposed to caregiving-related early adversity.

Experiences of caregiving-related adversity are common and one of the strongest predictors of internalizing psychopathology (i.e., anxiety and depression).

Adult onset wilms tumor.

Wilms tumor (WT) is the most common primary renal malignancy in the pediatric population and has very good overall survival with contemporary treatment protocols. In contrast, WT in adults is extremely rare and is associated with a poorer prognosis. The clinical presentation and imaging features of WT in adults are nonspecific and overlap with other more common forms of renal cancer, often leading to a delay in diagnosis.

Systematic empirical evaluation of individual base editing targets: validating therapeutic targets in USH2A and comparison of methods.

Base editing shows promise for the correction of human mutations at a higher efficiency than other repair methods and is especially attractive for mutations in large genes that are not amenable to gene augmentation therapy. Here, we demonstrate a comprehensive workflow for in vitro screening of potential therapeutic base editing targets for the USH2A gene and empirically validate the efficiency of adenine and cytosine base editor/guide combinations for correcting 35 USH2A mutations. Editing efficiency and bystander edits are compared between different target templates (plasmids versus transgenes) and assays (Next generation sequencing versus Sanger), as well as comparisons between unbiased empirical results and computational predictions.

COVID-19, Autism, and Isolation: Good Practices for Continuity of Care During the Pandemic.

The COVID-19 pandemic, and particularly the associated conditions of isolation, has detrimental effects on the mental health of the population that are not yet fully understood. Variables such as individual stress, anxiety, and tolerance to uncertainty may play a role in the ability of individuals to adapt to the isolation situation. In this context, it is necessary to pay attention to population groups that present difficulties in adapting to this situation of uncertainty, such as people with autism.

Evaluation of Lyso-Gb1 as a biomarker for Gaucher disease treatment outcomes using data from the Gaucher Outcome Survey.

Background: Patients with Gaucher disease (GD) require continual monitoring; however, lack of specific disease biomarkers was a significant challenge in the past. Glucosylsphingosine (lyso-Gb1) has been shown to be a reliable, key, specific, and sensitive biomarker for diagnosis, prognosis, and treatment response in clinical studies of patients with GD. We evaluated the change in lyso-Gb1 concentration over time following enzyme replacement therapy in patients with confirmed GD using real-world data from the Gaucher Outcome Survey disease registry.

Development and psychometric evaluation of the Brief Parenting Questionnaire.

Background: There is a paucity of brief self-report parenting measures validated for use in low- and middle-income countries (LMICs). We developed the Brief Parenting Questionnaire (BPQ), a 24-item self-report measure for use with parents of children ages 3-12.

Objective: We describe the development and evaluation of the psychometric properties of the BPQ, which was designed to include two subscales: warm and responsive parenting (WRP) and harsh parenting (HP).

Molecular and cellular characteristics of cerebrovascular cell types and their contribution to neurodegenerative diseases.

Many diseases and disorders of the nervous system suffer from a lack of adequate therapeutics to halt or slow disease progression, and to this day, no cure exists for any of the fatal neurodegenerative diseases. In part this is due to the incredible diversity of cell types that comprise the brain, knowledge gaps in understanding basic mechanisms of disease, as well as a lack of reliable strategies for delivering new therapeutic modalities to affected areas. With the advent of single cell genomics, it is now possible to interrogate the molecular characteristics of diverse cell populations and their alterations in diseased states.

Perceived healthiness of sugary drinks and related social norms among adults in five countries: evidence from the International Food Policy Study.

This study examined differences in perceived healthiness of sugary drinks and related social norms between countries, over time, and sociodemographic groups and associations with sugary drink intake.

Methods: This study used annual cross-sectional data from the International Food Policy Study from 2018 to 2021 in Australia, Canada, the United Kingdom, the United States, and Mexico.

Knights in shining armour and (M)others in life jackets: Women's experiences of advocating for care alone when suffering recurrent early pregnancy loss during the SARS-CoV-2 pandemic.

Background: Recurrent early pregnancy loss [rEPL] is a traumatic experience, marked by feelings such as grief and depression, and often anxiety. Despite this, the psychological consequences of rEPL are often overlooked, particularly when considering future reproductive health or approaching subsequent pregnancies. The SARS-CoV-2 pandemic led to significant reconfiguration of maternity care and a negative impact on the perinatal experience, but the specific impact on women's experience of rEPL has yet to be explored.

Niche-derived Semaphorin 4A safeguards functional identity of myeloid-biased hematopoietic stem cells.

Somatic stem cell pools comprise diverse, highly specialized subsets whose individual contribution is critical for the overall regenerative function. In the bone marrow, myeloid-biased hematopoietic stem cells (myHSCs) are indispensable for replenishment of myeloid cells and platelets during inflammatory response but, at the same time, become irreversibly damaged during inflammation and aging. Here we identify an extrinsic factor, semaphorin 4A (Sema4A), which non-cell-autonomously confers myHSC resilience to inflammatory stress.

From relaxed beliefs under psychedelics (REBUS) to revised beliefs after psychedelics (REBAS).

The Relaxed Beliefs Under pSychedelics (REBUS) model proposes that serotonergic psychedelics decrease the precision weighting of neurobiologically-encoded beliefs. We conducted a preliminary examination of two psychological assumptions of REBUS: (a) psychedelics foster acute relaxation and post-acute revision of confidence in mental-health-relevant beliefs; which (b) facilitate positive therapeutic outcomes and are associated with the entropy of EEG signals. Healthy individuals (N = 11) were administered 1 mg and 25 mg psilocybin 4-weeks apart.

Generative AI as a tool to accelerate the field of ecology.

The emergence of generative artificial intelligence (AI) models specializing in the generation of new data with the statistical patterns and properties of the data upon which the models were trained has profoundly influenced a range of academic disciplines, industry and public discourse. Combined with the vast amounts of diverse data now available to ecologists, from genetic sequences to remotely sensed animal tracks, generative AI presents enormous potential applications within ecology. Here we draw upon a range of fields to discuss unique potential applications in which generative AI could accelerate the field of ecology, including augmenting data-scarce datasets, extending observations of ecological patterns and increasing the accessibility of ecological data.
