Promoting Justice, Diversity, Equity, and Inclusion Through Caring Communities: Why It Matters to Occupational Therapy.

The global challenges humanity faces today, such as social and economic inequalities, occupational deprivation, racism, exclusion, displacement and migration crises, violence, wars, and political oppression, all contribute to health and participation inequities (Powell & Toppin, 2021). The depth and breadth of these inequities became strikingly evident and were exacerbated with the coronavirus 2019 pandemic (Khanijahani et al., 2021).

CRLF2 overexpression results in reduced B-cell differentiation and upregulated E2F signaling in the Dp16 mouse model of Down syndrome.

Children with Down syndrome (DS) are 10-fold more likely to develop B-cell acute lymphoblastic leukemia (B-ALL), with a higher frequency of rearrangements resulting in overexpression of cytokine receptor-like factor 2 (CRLF2). Here, we investigated the impact of CRLF2 overexpression on B-cell progenitor proliferation, immunophenotype, and gene expression profile in the Dp(16)1Yey (Dp16) mouse model of DS compared with wild-type (WT) mice. CRLF2 overexpression enhanced immature B-lymphoid colony development and increased the proportion of less differentiated pre-pro-B cells, with a greater effect in Dp16 versus WT.

Prevalence and Risk Factors of Neurologic Manifestations in Hospitalized Children Diagnosed with Acute SARS-CoV-2 or MIS-C.

Background: Our objective was to characterize the frequency, early impact, and risk factors for neurological manifestations in hospitalized children with acute severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection or multisystem inflammatory syndrome in children (MIS-C).

Methods: Multicenter, cross-sectional study of neurological manifestations in children aged <18 years hospitalized with positive SARS-CoV-2 test or clinical diagnosis of a SARS-CoV-2-related condition between January 2020 and April 2021. Multivariable logistic regression to identify risk factors for neurological manifestations was performed.

Widespread displacement of DNA- and RNA-binding factors underlies toxicity of arginine-rich cell-penetrating peptides.

Due to their capability to transport chemicals or proteins into target cells, cell-penetrating peptides (CPPs) are being developed as therapy delivery tools. However, and despite their interesting properties, arginine-rich CPPs often show toxicity for reasons that remain poorly understood. Using a (PR)n dipeptide repeat that has been linked to amyotrophic lateral sclerosis (ALS) as a model of an arginine-rich CPP, we here show that the presence of (PR)n leads to a generalized displacement of RNA- and DNA-binding proteins from chromatin and mRNA.

Mortality and other adverse outcomes in patients with type 2 diabetes mellitus admitted for COVID-19 in association with glucose-lowering drugs: a nationwide cohort study.

Background: Limited evidence exists on the role of glucose-lowering drugs in patients with COVID-19. Our main objective was to examine the association between in-hospital death and each routine at-home glucose-lowering drug both individually and in combination with metformin in patients with type 2 diabetes mellitus admitted for COVID-19. We also evaluated their association with the composite outcome of the need for ICU admission, invasive and non-invasive mechanical ventilation, or in-hospital death as well as on the development of in-hospital complications and a long-time hospital stay.

Transient exposure to miR-203 enhances the differentiation capacity of established pluripotent stem cells.

Full differentiation potential along with self-renewal capacity is a major property of pluripotent stem cells (PSCs). However, the differentiation capacity frequently decreases during expansion of PSCs in vitro. We show here that transient exposure to a single microRNA, expressed at early stages during normal development, improves the differentiation capacity of already-established murine and human PSCs.

Targeting STAT3 anti-apoptosis pathways with organic and hybrid organic-inorganic inhibitors.

Recurrence and drug resistance are major challenges in the treatment of acute myeloid leukemia (AML) that spur efforts to identify new clinical targets and active agents. STAT3 has emerged as a potential target in resistant AML, but inhibiting STAT3 function has proven challenging. This paper describes synthetic studies and biological assays for a naphthalene sulfonamide inhibitor class of molecules that inhibit G-CSF-induced STAT3 phosphorylation in cellulo and induce apoptosis in AML cells.

Atovaquone is active against AML by upregulating the integrated stress pathway and suppressing oxidative phosphorylation.

Atovaquone, a US Food and Drug Administration-approved antiparasitic drug previously shown to reduce interleukin-6/STAT3 signaling in myeloma cells, is well tolerated, and plasma concentrations of 40 to 80 µM have been achieved with pediatric and adult dosing. We conducted preclinical testing of atovaquone with acute myeloid leukemia (AML) cell lines and pediatric patient samples. Atovaquone induced apoptosis with an EC50 <30 µM for most AML lines and primary pediatric AML specimens.

Interleukin-6 levels predict event-free survival in pediatric AML and suggest a mechanism of chemotherapy resistance.

The tumor microenvironment can protect cancer cells from conventional anticancer therapies. Thus, targeting these protective mechanisms could eradicate therapy-resistant cancer cells and improve outcomes. Interleukin-6 (IL-6) provides extrinsic protection for several solid tumors and multiple myeloma.

The Scope of Practice of Occupational Therapy in U.S. Criminal Justice Settings.

Tricuspid Regurgitation and Mortality Risk Across Left Ventricular Systolic Function in Acute Heart Failure.

Background: Tricuspid regurgitation (TR) is a common echocardiographic finding that has been related to adverse outcome under various clinical scenarios. Nevertheless, evidence supporting its prognostic value in heart failure (HF) is scarce, and, in most cases, contradictory. We evaluated the association of TR grade with 1-year all-cause mortality in acute HF (AHF).

Discrete perturbation theory for continuous soft-core potential fluids.

In this work, we present an equation of state for an interesting soft-core continuous potential [G. Franzese, J. Mol.

Prognostic implications of tissue Doppler imaging-derived e/ea ratio in acute heart failure patients.

Background: Tissue Doppler-derived transmitral to mitral annular early diastolic velocity ratio (E/Ea), as a noninvasive estimation of left ventricular (LV) filling pressures, is a strong prognosticator in various cardiac scenarios including chronic heart failure; nevertheless, its utility for risk stratification in the whole spectrum of acute heart failure (AHF) patients remains elusive. Thus, the aim of this study was to determine the association between E/Ea ratio and 1-year mortality in nonselected patients with AHF.

Methods: The study included 417 consecutive patients admitted for AHF.

Modeling metabolism: a window toward a comprehensive interpretation of networks in cancer.

Given the multi-factorial nature of cancer, uncovering its metabolic alterations and evaluating their implications is a major challenge in biomedical sciences that will help in the optimal design of personalized treatments. The advance of high-throughput technologies opens an invaluable opportunity to monitor the activity at diverse biological levels and elucidate how cancer originates, evolves and responds under drug treatments. To this end, researchers are confronted with two fundamental questions: how to interpret high-throughput data and how this information can contribute to the development of personalized treatment in patients.

Systems biology of cancer: moving toward the integrative study of the metabolic alterations in cancer cells.

One of the main objectives in systems biology is to understand the biological mechanisms that give rise to the phenotype of a microorganism by using high-throughput technologies (HTs) and genome-scale mathematical modeling. The computational modeling of genome-scale metabolic reconstructions is one systemic and quantitative strategy for characterizing the metabolic phenotype associated with human diseases and potentially for designing drugs with optimal clinical effects. The purpose of this short review is to describe how computational modeling, including the specific case of constraint-based modeling, can be used to explore, characterize, and predict the metabolic capacities that distinguish the metabolic phenotype of cancer cell lines.

Genetic footprints of Iberian cattle in America 500 years after the arrival of Columbus.

Background: American Creole cattle presumably descend from animals imported from the Iberian Peninsula during the period of colonization and settlement, through different migration routes, and may have also suffered the influence of cattle directly imported from Africa. The introduction of European cattle, which began in the 18th century, and later of Zebu from India, has threatened the survival of Creole populations, some of which have nearly disappeared or were admixed with exotic breeds. Assessment of the genetic status of Creole cattle is essential for the establishment of conservation programs of these historical resources.

Design And Method: Seventy-nine patients [mean age 57 (standard deviation 11) years, 47 men, BMI 28 (4), office BP 151 (25)/92 (14) mmHg, estimated glomerular filtration rate 28 (14) ml/min per 1.73 m3] were included.

Prolactin's role in the early stages of liver regeneration in rats.

Liver regeneration after partial hepatectomy (PHx) is a complex process that is regulated by hemodynamic changes, the modulation of cytokines and growth factors, and the activation of immediate early transcription factors that lead to a round of hepatocyte mitosis. Among the factors involved, the pituitary hormone prolactin (PRL) has been shown to induce a hepatotrophic response after partial hepatectomy similar to that caused by phorbol esters; and in isolated hepatocytes PRL triggers a mitogenic response. However, it is becoming clear that PRL exerts a dual role acting in proliferation and differentiation processes.
