Students in STEM know well the stress, challenge, and effort that accompany college exams. As a widely recognizable feature of the STEM classroom experience, high-stakes assessments serve as crucial cultural gateways in shaping both preparation and motivation for careers. In this essay, we identify and discuss issues of power around STEM exams to further the understanding of exam practices that can unjustly hold students back.

Despite this, translating this information into messages for consumers that change behavior has been difficult. There have been population-level social marketing campaigns as well as several smaller campaigns directed specifically toward children, which have demonstrated small increases in consumption.

These capabilities have been implemented in order to reveal the complex spatiotemporal correlations that govern the oxidation of graphitic systems spanning atomic-, nano-, and meso-length scales. In this study, the 3 nm periodic moiré pattern of monolayer and bilayer graphene on Ru(0001) provides a diverse palette of potential scattering and binding sites at the interface for ground state atomic oxygen.

In the intestine, dietary and microbial cues are particularly important in the regulation of organ homeostasis. However, whether enteric endothelial cells actively sense and integrate such signals is currently unknown.

A focus on enjoyment and learning to like eating vegetables at an early age is critical to forming favourable lifelong eating habits. Coordinated work is needed to ensure vegetables are available and promoted in a range of settings, using evidence-based initiatives, to create an environment that will support children’s acceptance of vegetables.

Methods: A comprehensive literature search was conducted from September 2021 to May 2022. Clinical studies, systematic reviews and meta-analyses, and other evidence conducted on human participants were identified that were published in English from MEDLINE (through PubMed), EMBASE, the Cochrane Library, Agency for Healthcare Research and Quality, and other selected databases relevant to this guideline.

Primary adenocarcinoma of the appendix is an uncommon malignancy of the gastrointestinal tract. The most common symptom is right lower abdominal pain, which could be indistinguishable from acute appendicitis. However, the clinical presentation is usually non-specific.

With increasing evidence for the synergy between human and planetary health, FBDGs have started to consider the environmental sustainability of food choices. However, the number of countries that discuss environmental sustainability in their guidelines is unknown.

As yields in controlled fusion experiments increase, the radiation tolerance of scintillator candidates for use in instrumentation is of particular importance. High radiation exposure can damage scintillating materials and alter the optical properties.

In the setting of bleeding related to coagulopathies, oftentimes physicians try to reverse coagulopathy through a variety of methods including the use of vitamin K and fresh frozen plasma. Rarely, attempts at reversing coagulopathy are unsuccessful due to severe disease or factor inhibitors.

It is uncommon comorbidity in patients with Hashimoto's thyroiditis (HT). Myxedema is a severe form of hypothyroidism that is commonly related to new diagnoses, medication non-compliance, or malabsorption of thyroid supplementation that can have life-threatening associated conditions like heart failure and coma.

BS is commonly associated with repeated episodes of severe retching, straining, or vomiting. Diabetic ketoacidosis (DKA), a serious acute complication of diabetes, is characterized in part by laboratory findings of profound hyperglycemia and ketoacidosis.

As a result, it is reasonable to anticipate increased use of colchicine within the cardiovascular specialty. However, colchicine is metabolized by cytochrome P450 3A4 (CYP3A4) and a substrate of the efflux transporter, P-glycoprotein (P-gp), creating the potential for clinically significant drug-drug interactions (DDIs).
View Article and Find Full Text PDFAcute promyelocytic leukemia (APL) typically presents with complications from pancytopenia, generalized weakness, and hemorrhagic findings, with a distinguishing feature being the associated predilection of disseminated intravascular coagulation (DIC). APL is characterized by the halting of cellular differentiation in the promyelocyte stage, and balanced chromosomal translocation t(15;17) (q24;q21) that forms the promyelocytic leukemia-retinoic acid receptor-α (PML-RARA) fusion protein present in 95% of cases. APL has a high rate of early mortality secondary to coagulopathy, lending to the imperative need to begin a differentiation agent as soon as the disease is suspected, with all-trans retinoic acid (ATRA) being the most common differentiation agent.

CG is almost always associated with human immunodeficiency virus (HIV) infection but is rarely from other infectious sources such as parvovirus, Epstein-Barr virus, cytomegalovirus, and SARS-CoV-2. CG has also been reported to be related to other etiologies such as genetic disorders, lupus, malignancy, and post-renal transplant but is exceedingly rare when related to hepatitis C virus (HCV).

They have been demonstrated efficacy in a variety of patients populations to reduce atherosclerotic cardiovascular disease (ASCVD) risk. Like any pharmacologic therapy, however, they are not without possible adverse effects that can lead to discontinuation, thus leading to a loss of benefit.

Evidence suggests application of co-design in various health domains has been growing; however, few public-facing digital interventions have been co-designed to specifically address the needs of adults at risk of Type 2 diabetes (T2D). This study aims to: (1) co-design, with key stakeholders, a digital dietary intervention to promote health behaviour change among adults at risk of T2D, and (2) evaluate the co-design process involved in developing the intervention prototype.

Cardiovascular (CV) disease remains the leading cause of death in the United States. In addition to lifestyle modifications, current guidelines primarily focus on lowering low-density lipoprotein cholesterol (LDL-C) to reduce atherosclerotic CV disease risk. However, despite aggressive management, a degree of residual risk remains, suggesting that focusing on lowering LDL-C alone may be inadequate and that other lipid parameters may need to be targeted.

We report the first documented case of bilateral pulmonary embolism in the setting of PCGDTL in a 30-year-old woman who presented with acute dyspnea.

Design: We used multiparametric flow cytometry, histological assessment and novel human tissue coculture systems to interrogate the ex vivo phenotype, function and generation of the intrahepatic CD4 T-cell compartment.
