Comparative analysis of the bioaccumulation of bisphenol A in the blood serum and follicular fluid of women living in two areas with different environmental impacts.

Introduction: Bisphenol A (BPA) is a common contaminant widely used in many industrial sectors. Because of its wide use and dispersion, it can be accumulated in living human bodies through both oral assumption and nondietary routes. BPA exhibits hormone-like properties, falling under the class of endocrine disruptors; therefore, it can alter relevant physiological functions.

The empty code cart: Drug shortages over time.

Purpose: In high-acuity situations such as cardiac arrest, clinicians rely on prepared medications stocked in code carts to provide timely and accurate pharmacotherapy. We examined shortage trends for medications commonly used in code carts.

Methods: Drug shortage data from 2001 to 2022 were retrieved from the University of Utah Drug Information Service (UUDIS) to characterize shortages reported for commonly used code cart medications.

Utilization and outcome disparities in allogeneic hematopoietic stem cell transplant in the United States.

Allogeneic hematopoietic stem cell transplant (allo-HSCT) is increasingly being used in the United States (US) and across the world as a curative therapeutic option for patients with certain high-risk hematologic malignancies and non-malignant diseases. However, racial and ethnic disparities in utilization of the procedure and in outcome following transplant remain major problems. Racial and ethnic minority patients are consistently under-represented in the proportion of patients who undergo allo-HSCT in the US.

Descriptive Analysis and Factors Influencing Survival in Patients With Primary Cutaneous Gamma-Delta T Cell Lymphoma. A Retrospective National Cancer Database Study.

Background: Gamma delta T cells gives rise to a rare malignancy called Primary cutaneous Gamma-Delta T cell lymphoma (PCGDTCL).

Methods: From the National Cancer Database (NCDB), 110 (0.015%) patients with PCGDTCL were identified.

Behavioral Modifications in Children after Repeated Sedation with Nitrous Oxide for Dental Treatment: A Retrospective Study.

Sedation with nitrous oxide (NO) has been widely used as a viable alternative to general anesthesia to perform dental treatments in uncooperative or anxious children. The purpose of this retrospective study is to assess if repeated sedations with NO can improve collaboration of uncooperative children. The medical records of 650 children, aged between 3 and 14 years, who underwent at least two sedations, were consulted.

Cerebral Creatine Deficiency Affects the Timing of Oligodendrocyte Myelination.

Cerebral creatine deficiency syndrome (CCDS) is an inborn error of metabolism characterized by intellectual delays, seizures, and autistic-like behavior. However, the role of endogenously synthesized creatine on CNS development and function remains poorly understood. Here, magnetic resonance spectroscopy of adult mouse brains from both sexes revealed creatine synthesis is dependent on the expression of the enzyme, guanidinoacetate methyltransferase (GAMT).

Liposomal Daunorubicin and Cytarabine, a Potential Therapy for Blastic Plasmacytoid Dendritic Cell Neoplasm.

Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a rare aggressive malignancy with poor outcomes. Although novel options like tagraxofusp, a CD123-directed cytotoxin, has emerged and is promising, treatment options are very limited in the relapsed and recurrent setting. We present a case of refractory BPDCN in a 62-year-old man who showed a complete bone marrow response to liposomal daunorubicin and cytarabine (vyxeos).

Systemic Cancer Therapy Does Not Significantly Impact Early Vaccine-Elicited SARS-CoV-2 Immunity in Patients with Solid Tumors.

mRNA vaccines have been shown to be safe and effective in individuals with cancer. It is unclear, however, if systemic anti-cancer therapy impacts the coordinated cellular and humoral immune responses elicited by SARS-CoV-2 mRNA vaccines. To fill this knowledge gap, we assessed SARS-CoV-2 mRNA vaccine-elicited immunity in a cohort of patients with advanced solid tumors either under observation or receiving systemic anti-cancer therapy.

Conscious Sedation in Dentistry for the Management of Pediatric Patients with Autism: A Narrative Review of the Literature.

(1) Background: the variety of autism spectrum disorder makes the definition of guidelines for dental care a challenging task. The aim of this review was to evaluate the literature concerning the use of conscious sedation for dental treatments in pediatric autistic patients. (2) Methods: we searched MEDLINE/PubMed, EMBASE, Cochrane databases in order to identify pertinent studies.

Efficacy and safety of the BNT162b2 mRNA COVID-19 vaccine in participants with a history of cancer: subgroup analysis of a global phase 3 randomized clinical trial.

Introduction: Individuals with an underlying malignancy have high risk of poor COVID-19 outcomes. In clinical trials, COVID-19 vaccines were safe and efficacious against infection, hospitalization, and death, but most trials excluded participants with cancer. We report results from participants with a history of past or active neoplasm (malignant or benign/unknown) and up to 6 months' follow-up post-dose 2 from the placebo-controlled, observer-blinded trial of the 2-dose BNT162b2 mRNA COVID-19 vaccine.

Interleukin-2-inducible T-cell kinase (Itk) signaling regulates potent noncanonical regulatory T cells.

Regulatory T cells (Tregs) play an important role in controlling autoimmunity and limiting tissue damage and inflammation. IL2-inducible T cell kinase (Itk) is part of the Tec family of tyrosine kinases and is a critical component of T cell receptor mediated signaling. Here, we showed that either genetic ablation of Itk signaling or inhibition of Itk signaling pathways resulted in increased frequency of "noncanonical" CD4 CD25 FOXP3 Tregs (ncTregs), as well as of "canonical" CD4 CD25 FOXP3 Tregs (canTregs).

The unusual case of babesiosis causing disseminated intravascular coagulation with hemophagocytic lymphohistiocytosis.

Babesiosis is increasing in the elderly due to an age-related decline in immunity. Prompt diagnosis with blood smear and PCR prevent life-threatening complications, like DIC and HLH. Studies focusing on pathophysiology and risk factors are needed.

Accidental Ixazomib Overdose in a Patient With Multiple Myeloma.

Multiple myeloma is the second most common hematological malignancy. Ixazomib is the first oral proteasome inhibitor approved in the United States for the management of multiple myeloma who have received at least one prior treatment. The availability of oral chemotherapeutic agents for the management of multiple myeloma has made it easier for patients who do not have to come to the hospital for chemotherapy infusions.

Targeting SLP76:ITK interaction separates GVHD from GVL in allo-HSCT.

Allogeneic hematopoietic stem cell transplantation (allo-HSCT) is a curative therapy for hematological malignancies, due to graft-versus-leukemia (GVL) activity mediated by alloreactive donor T cells. However, graft-versus-host disease (GVHD) is also mediated by these cells. Here, we assessed the effect of attenuating TCR-mediated SLP76:ITK interaction in GVL vs.

Neutron Polarimetry Using a Polarized He Cell for the aCORN Experiment.

The neutron polarization of the NG-C beamline at the NIST Center for Neutron Research was measured as part of the aCORN neutron beta decay experiment. Neutron transmission through a polarized He spin filter cell was recorded while adiabatic fast passage (AFP) nuclear magnetic resonance (NMR) reversed the polarization direction of the He in an eight-step sequence to account for drifts. The dependence of the neutron transmission on the spin filter direction was used to calculate the neutron polarization.

Neonatal teeth: Importance of histological findings in management update.

Background: Presence of teeth in a newborn represents a rare finding and a disturbance of biological chronology of teeth. The aim of this paper is to report two cases with neonatal teeth histologically examined.

Case Report: In this paper two cases of patients with neonatal teeth are reported and histological examinations of three extracted teeth are described.

Targeting Interleukin-2-Inducible T-Cell Kinase (ITK) Differentiates GVL and GVHD in Allo-HSCT.

Allogeneic hematopoietic stem cell transplantation is a potentially curative procedure for many malignant diseases. Donor T cells prevent disease recurrence graft-versus-leukemia (GVL) effect. Donor T cells also contribute to graft-versus-host disease (GVHD), a debilitating and potentially fatal complication.

Optimizing magnetically shielded solenoids.

An important consideration when designing a magnetostatic cavity for various applications is to maximize the ratio of the volume of field homogeneity to the overall size of the cavity. We report a design of a magnetically shielded solenoid that significantly improves the transverse field gradient averaged over a volume of 1000 cm by placing compensation coils around the holes in the mu-metal end caps rather than the conventional design in which the compensation coils are placed on the main solenoid. Our application is polarized He-based neutron spin filters, and our goal was to minimize the volume-averaged transverse field gradient, thereby the gradient induced relaxation time, over a He cell.

Electric Field Imaging Using Polarized Neutrons.

We experimentally demonstrate that electrically neutral particles, neutrons, can be used to directly visualize the electrostatic field inside a target volume that can be physically isolated or occupied. Electric field images are obtained using a spin-polarized neutron beam with a recently developed polarimetry method for polychromatic beams that permits detection of a small angular change in spin orientation. This Letter may enable a new diagnostic technique sensitive to the structure of electric potential, electric polarization, charge distribution, and dielectric constant by imaging spatially dependent electric fields in objects that cannot be accessed by other probes.

The kappa opioid receptor agonist U50,488H did not affect brain-stimulation reward while it elicited conditioned place aversion in mice.

Objective: Selective kappa opioid receptor (KOR) agonists were shown to produce a dose-dependent depression of brain-stimulation reward (BSR) in the rat intracranial self-stimulation (ICSS) tests. However, limited studies using mice produced less conclusive results. Here the effects of U50,488H were re-examined on BSR in mice with a larger cohort of animals.

Comparing different sperm separation techniques for ART, through quantitative evaluation of p53 protein.

Context: In the last 10 years, assisted reproductive technologies (ARTs) have offered infertile couples an opportunity to complete their reproductive project. However, the high failure rate could be explained with the complex human reproduction system. In ART, the decrease of the success is due to the conditions far from the natural ones.
