Immunoresponsive Gene 1 Facilitates TLR4-agonist-Induced Augmentation of Innate Antimicrobial Immunity.

Treatment with the toll-like receptor (TLR) 4 agonist monophosphoryl lipid A (MPLA) conditions innate immunocytes to respond robustly to subsequent infection, a phenotype termed innate immune memory. Our published studies show that metabolic reprogramming of macrophages is a prominent feature of the memory phenotype. We undertook studies to define the functional contributions of tricarboxylic acid (TCA) cycle reprogramming to innate immune memory.

Use of an Integrated Pulmonary Index pathway decreased unplanned ICU admissions in elderly patients with rib fractures.

Unlabelled: Unplanned intensive care unit (ICU) admission (UIA) is a Trauma Quality Improvement Program benchmark that is associated with increased morbidity, mortality, and length of stay (LOS). Elderly patients with multiple rib fractures are at increased risk of respiratory failure. The Integrated Pulmonary Index (IPI) assesses respiratory compromise by incorporating SpO, respiratory rate, pulse, and end-tidal CO to yield an integer between 1 and 10 (worst and best).

Costs of Providing Preexposure Prophylaxis for HIV Prevention at Community Health Centers in the United States.

Objective: Preexposure prophylaxis (PrEP) is recommended for people at risk of acquiring HIV. We assessed billable costs associated with PrEP delivery at community health centers.

Methods: The Sustainable Health Center Implementation PrEP Pilot (SHIPP) study is an observational cohort of people receiving daily oral PrEP at participating federally qualified health centers and other community health centers.

Maize varietal replacement in Eastern and Southern Africa: Bottlenecks, drivers and strategies for improvement.

Seed security is vital for food security. Rapid-cycle, climate-adaptive breeding programs and seed systems that deliver new, elite varieties to farmers to replace obsolete ones can greatly improve the productivity of maize-based cropping systems in sub-Saharan Africa (SSA). Despite the importance and benefits of accelerated varietal turnover to climate change adaptation and food security, the rate of maize varietal replacement in SSA is slow.

Elite rhetoric can undermine democratic norms.

Democratic stability depends on citizens on the losing side accepting election outcomes. Can rhetoric by political leaders undermine this norm? Using a panel survey experiment, we evaluate the effects of exposure to multiple statements from former president Donald Trump attacking the legitimacy of the 2020 US presidential election. Although exposure to these statements does not measurably affect general support for political violence or belief in democracy, it erodes trust and confidence in elections and increases belief that the election is rigged among people who approve of Trump's job performance.

Ultrasound Evaluation of Gastric Emptying Time in Healthy Term Neonates after Formula Feeding.

Background: The current American Society of Anesthesiologists fasting guideline for formula-fed infants in the periprocedural setting is 6 h. Prolonged fasting in very young infants is associated with an increased risk for hypoglycemia and dehydration as well as patient discomfort and patient/parental dissatisfaction. This study aimed to determine the time to gastric emptying in healthy neonates after formula feeding by serially evaluating the gastric antrum with ultrasound.

Executive functions in children with heart disease: a systematic review and meta-analysis.

Context: People with CHD are at increased risk for executive functioning deficits. Meta-analyses of these measures in CHD patients compared to healthy controls have not been reported.

Objective: To examine differences in executive functions in individuals with CHD compared to healthy controls.

Associations Between Social Support and Social Media Use Among Young Adult Cisgender MSM and Transgender Women Living With HIV.

Social media platforms offer the opportunity to develop online social networks. Use of these platforms has been particularly attractive to younger sexual and gender minority individuals as well as those living with HIV. This cross-sectional study examined the perceived level of social support and associations with social media use among youth and young adult cisgender men who have sex with men (MSM) and transgender (trans) women living with HIV and examined these associations by gender identity.

Geranylgeranyl generosity: a new prenyl-transferase gives a fat to a SNARE protein.

Protein prenylation, a well-defined protein consensus motifs direct modification by one of three prenyl-transferases, has been an area of fairly settled science for 20 or 30 years. Protein prenylation, the specific prenyl modification (farnesyl or geranylgeranyl), as well as the prenyl-transferases involved can be inferred by protein sequence. Two new papers now upset this settled wisdom with the discovery of a fourth prenyl-transferase, namely geranylgeranyl-transferase-III (GGTase-III) (Kuchay et al, 2019; Shirakawa et al, 2020).

Redefining the Trauma Triage Matrix: The Role of Emergent Interventions.

Background: A tiered trauma team activation (TTA) system aims to allocate resources proportional to the patient's need based upon injury burden. The current metrics used to evaluate appropriateness of TTA are the trauma triage matrix (TTM), need for trauma intervention (NFTI), and secondary triage assessment tool (STAT).

Materials And Methods: In this retrospective study, we compared the effectiveness of the need for an emergent intervention within 6 h (NEI-6) with existing definitions.

Non-Hodgkin Lymphomas: Malignancies Arising from Mature B Cells.

Non-Hodgkin lymphomas (NHLs) are a diverse group of entities, both clinically and molecularly. Here, we review the evolution of classification schemes in B-cell lymphoma, noting the now standard WHO classification system that is based on immune cell-of-origin and molecular phenotypes. We review how lymphomas arise throughout the B-cell development process as well as the molecular and clinical features of prominent B-cell lymphomas.

Asymmetric synthesis of cyclopentanones through dual Lewis acid-catalysed [3+2]-cycloaddition of donor-acceptor cyclopropanes with ketenes.

When InBr3-EtAlCl2 (15-30 mol%) was used as a dual Lewis acid system to promote the formal [3+2]-cycloaddition of enantioenriched donor-acceptor cyclopropanes with ketenes, cyclopentanones were formed in good to excellent yields (84-99%, 18 examples), and with excellent transfer of chirality (15 examples, 90% ee to >99% ee).

Statistical Methodology of the National Immunization Survey, 2005-2014.

Genetic and Functional Drivers of Diffuse Large B Cell Lymphoma.

Diffuse large B cell lymphoma (DLBCL) is the most common form of blood cancer and is characterized by a striking degree of genetic and clinical heterogeneity. This heterogeneity poses a major barrier to understanding the genetic basis of the disease and its response to therapy. Here, we performed an integrative analysis of whole-exome sequencing and transcriptome sequencing in a cohort of 1,001 DLBCL patients to comprehensively define the landscape of 150 genetic drivers of the disease.

Post-mortem molecular profiling of three psychiatric disorders.

Background: Psychiatric disorders are multigenic diseases with complex etiology that contribute significantly to human morbidity and mortality. Although clinically distinct, several disorders share many symptoms, suggesting common underlying molecular changes exist that may implicate important regulators of pathogenesis and provide new therapeutic targets.

Methods: We performed RNA sequencing on tissue from the anterior cingulate cortex, dorsolateral prefrontal cortex, and nucleus accumbens from three groups of 24 patients each diagnosed with schizophrenia, bipolar disorder, or major depressive disorder, and from 24 control subjects.

Targeting the Ras palmitoylation/depalmitoylation cycle in cancer.

The Ras proteins are well-known drivers of many cancers and thus represent attractive targets for the development of anticancer therapeutics. Inhibitors that disrupt the association of the Ras proteins with membranes by blocking the addition of the farnesyl lipid moiety to the Ras C-terminus failed in clinical trials. Here, we explore the possibility of targeting a second lipid modification, S-acylation, commonly referred to as palmitoylation, as a strategy to disrupt the membrane interaction of specific Ras isoforms.

Enteropathy-associated T cell lymphoma subtypes are characterized by loss of function of SETD2.

Enteropathy-associated T cell lymphoma (EATL) is a lethal, and the most common, neoplastic complication of celiac disease. Here, we defined the genetic landscape of EATL through whole-exome sequencing of 69 EATL tumors. was the most frequently silenced gene in EATL (32% of cases).

Genome-wide DNA methylation measurements in prostate tissues uncovers novel prostate cancer diagnostic biomarkers and transcription factor binding patterns.

Background: Current diagnostic tools for prostate cancer lack specificity and sensitivity for detecting very early lesions. DNA methylation is a stable genomic modification that is detectable in peripheral patient fluids such as urine and blood plasma that could serve as a non-invasive diagnostic biomarker for prostate cancer.

Methods: We measured genome-wide DNA methylation patterns in 73 clinically annotated fresh-frozen prostate cancers and 63 benign-adjacent prostate tissues using the Illumina Infinium HumanMethylation450 BeadChip array.

The Genetic Basis of Hepatosplenic T-cell Lymphoma.

Hepatosplenic T-cell lymphoma (HSTL) is a rare and lethal lymphoma; the genetic drivers of this disease are unknown. Through whole-exome sequencing of 68 HSTLs, we define recurrently mutated driver genes and copy-number alterations in the disease. Chromatin-modifying genes, including , and , were commonly mutated in HSTL, affecting 62% of cases.

Physical Activity and Cognitive Development: A Meta-Analysis.

Research Question: Is there an association between regular exercise, defined as a structured program of increased physical activity at least 1 month in duration, and improvements in measures of executive functions compared with children who engage in their normal daily activities?

Context: The association between increased physical activity and changes in performance on tasks of executive functions have not been well elucidated in children. Executive functioning is important to intellectual development and academic success in children, and inexpensive, nonpharmacological methods for the treatment of executive dysfunction represent an attractive interventional target.

Objective: To estimate the effect of a structured regular exercise program on neuropsychological domains of executive function in children ages 7 to 12.
