Adolescent high fat diet alters the transcriptional response of microglia in the prefrontal cortex in response to stressors in both male and female mice.

Both obesity and high fat diets (HFD) have been associated with an increase in inflammatory gene expression within the brain. Microglia play an important role in early cortical development and may be responsive to HFD, particularly during sensitive windows, such as adolescence. We hypothesized that HFD during adolescence would increase proinflammatory gene expression in microglia at baseline and potentiate the microglial stress response.

Analytical propagation model for underwater free-space optical communication through realistic levels of oceanic absorption and scattering.

Optical communications (OC) through water bodies is an attractive technology for a variety of applications. Thanks to current single-photon detection capabilities, OC receiver systems can reliably decode very weak transmitted signals. This is the regime where pulse position modulation is an ideal scheme.

The Impact of Restricted Clinical Experiences During a Pandemic on Newly Graduated Nurses' Experiences: A Descriptive Study.

A multihospital study examined the impact of restricted clinical opportunities during COVID-19 on newly graduated nurses' experiences, self-reported competence, and self-reported errors upon entry into a nurse residency program and at 6 months. Newly graduated nurses' experiences (n = 2,005) were described using comparative data from cohorts before and during restricted experiences across 22 hospitals; minimal differences were observed. Nursing professional development specialists can utilize this information when creating and sustaining transition-to-practice programs.

Actinobacteriophage Djungelskog was isolated from a sample of degraded organic material in Poughkeepsie, NY, using . Its genome is 54,512 bp and encodes 86 putative protein-coding genes. Djungelskog has a siphovirus morphology and is assigned to cluster AW based on gene content similarity to actinobacteriophages.

Early life cancer and chemotherapy lead to cognitive deficits related to alterations in microglial-associated gene expression in prefrontal cortex.

Children that survive leukemia are at an increased risk for cognitive difficulties. A better understanding of the neurobiological changes in response to early life chemotherapy will help develop therapeutic strategies to improve quality of life for leukemia survivors. To that end, we used a translationally-relevant mouse model consisting of leukemic cell line (L1210) injection into postnatal day (P)19 mice followed by methotrexate, vincristine, and leucovorin chemotherapy.

Hypertensive emergencies: guidelines and best-practice recommendations.

Due to a variety of demographic and public health factors, the number of emergency department visits related to hypertensive emergencies has increased dramatically in recent decades, making it imperative that clinicians clearly understand the current treatment guidelines and definitions for the spectrum of hypertensive disease. This issue reviews current evidence on identifying and managing hypertensive emergencies and the differences between expert opinions on diagnosing and managing these emergencies. Clear protocols differentiating patients with hypertension from patients with hypertensive emergencies are needed to appropriately manage this patient population.

Objectives: To evaluate the efficacy of a cash transfer and nutrition education program on dietary diversity among children in Liberia. We hypothesized that a multi-pronged intervention would result in improved dietary diversity among children.

Methods: We conducted a three-armed, cluster-randomized study in 42 communities (12 children per community) in Grand Gedeh County, Liberia, over a 12-month period.

Photon path distributions in optically thin slabs.

The probability distribution function of photon path length in a scattering medium contains valuable information on that medium. While strongly scattering optically thick media have been extensively studied, in particular, with resort to the diffusion approximation, optically thin media have received much less attention. Here, we derive the probability distribution functions for the lengths of singly- and twice-scattered photon paths in an isotropically scattering slab of optical thickness τ, for both reflected and transmitted photons.

Design of a randomized controlled trial to assess the comparative effectiveness of a multifaceted intervention to improve three-year adherence to colorectal cancer screening among patients cared for in rural community health centers.

Colorectal cancer (CRC) screening has been shown to decrease CRC mortality, yet significant disparities persist among those living in rural areas, from minority backgrounds, and those having low income. The purpose of this two-arm randomized controlled trial is to test the effectiveness and fidelity of a stepped care (increasing intensity as needed) approach to promoting 3-year adherence to CRC screening via fecal immunochemical testing (FIT) or colonoscopy in rural community clinics serving high rates of low-income and minority patients. We hypothesize that, compared to enhanced usual care (EUC), patients receiving the multifaceted CRC screening intervention will demonstrate higher rates of CRC screening completion over 3 years.

Structural Features of a Family of Coumarin-Enamine Fluorescent Chemodosimeters for Ion Pairs.

A family of coumarin-enamine chemodosimeters is evaluated for their potential use as fluorescent molecular probes for multiple analytes [cadmium(II), cobalt(II), copper(II), iron(II), nickel(II), lead(II), and zinc(II)], as their chloride and acetate salts. These fluorophores displayed excellent optical spectroscopic modulation when exposed to ion pairs with different Lewis acidic and basic properties in dimethyl sulfoxide (DMSO). The chemodosimeters were designed to undergo excited-state intramolecular proton transfer (ESIPT), which leads to significant Stokes shifts (ca.

Dataset-chemokines, cytokines, and biomarkers in the saliva of children with Sjögren's syndrome.

Sjögren's syndrome is an autoimmune disease that can also occur in children. The disease is not well defined and there is limited information on the presence of chemokines, cytokines, and biomarkers (CCBMs) in the saliva of children that could improve their disease diagnosis. In a recent study [1], we reported a large dataset of 105 CCBMs that were associated with both lymphocyte and mononuclear cell functions [2] in the saliva of 11 children formally diagnosed with Sjögren's syndrome and 16 normal healthy children.

Management Options for Sialadenosis.

Sialadenosis (sialosis) is a chronic, noninflammatory, nonneoplastic, bilateral, often painless enlargement of the salivary glands, most frequently affecting the parotid glands. Approximately 50% of cases are associated with an underlying disease process. The pathogenesis of sialadenosis is unknown but likely results from an autonomic neuropathy.

A Case of Multisystem Inflammatory Syndrome in Children Following SARS-CoV-2 Infection in a Rural Emergency Department.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV2), also known as COVID-19, has rapidly spread across the globe resulting in a worldwide pandemic. This disease has such varying presentation within the population. Although rare, multisystem inflammatory syndrome in children (MIS-C) is a potentially fatal complication of SARS-CoV2 infection and can be easily missed in the early stages.

A distinguishing profile of chemokines, cytokines and biomarkers in the saliva of children with Sjögren's syndrome.

Objective: SS is an autoimmune disease most commonly diagnosed in adults but can occur in children. Our objective was to assess the presence of chemokines, cytokines and biomarkers (CCBMs) in saliva from these children that were associated with lymphocyte and mononuclear cell functions.

Methods: Saliva was collected from 11 children diagnosed with SS prior to age 18 years and 16 normal healthy children.

Heterogeneous mass distribution of the rubble-pile asteroid (101955) Bennu.

The gravity field of a small body provides insight into its internal mass distribution. We used two approaches to measure the gravity field of the rubble-pile asteroid (101955) Bennu: (i) tracking and modeling the spacecraft in orbit about the asteroid and (ii) tracking and modeling pebble-sized particles naturally ejected from Bennu's surface into sustained orbits. These approaches yield statistically consistent results up to degree and order 3, with the particle-based field being statistically significant up to degree and order 9.

This paper presents the physical basis of the EPIC cloud product algorithms and an initial evaluation of their performance. Since June 2015, EPIC has been providing observations of the sunlit side of the Earth with its 10 spectral channels ranging from the UV to the near-IR. A suite of algorithms has been developed to generate the standard EPIC Level 2 Cloud Products that include cloud mask, cloud effective pressure/height, and cloud optical thickness.

Episodes of particle ejection from the surface of the active asteroid (101955) Bennu.

Active asteroids are those that show evidence of ongoing mass loss. We report repeated instances of particle ejection from the surface of (101955) Bennu, demonstrating that it is an active asteroid. The ejection events were imaged by the OSIRIS-REx (Origins, Spectral Interpretation, Resource Identification, and Security-Regolith Explorer) spacecraft.

Evaluation of Step-Counting Interventions Differing on Intensity Messages.

Background: Step-counting interventions with discrepant intensity emphases may elicit different effects.

Methods: A total of 120 sedentary/low-active, postmenopausal women were randomly assigned to one of the following 3 groups: (1) 10,000 steps per day (with no emphasis on walking intensity/speed/cadence; basic intervention, 49 completers), (2) 10,000 steps per day and at least 30 minutes in moderate intensity (ie, at a cadence of at least 100 steps per minute; enhanced intervention, 47 completers), or (3) a control group (19 completers). NL-1000-determined steps and active minutes (a device-specific indicator of time at moderate+ intensity) were collected as process variables during the 12-week intervention.

The inter-rater reliability of the Wheelchair Interface Questionnaire.

Purpose: Wheelchair outcomes measures are useful to support evidence-based practice in wheelchair provision, especially in low- and middle-income countries (LMIC). The Wheelchair Interface Questionnaire (WIQ) was developed to provide a professional perspective on the quality of the interface between a wheelchair and its user. Studies conducted during the development of the WIQ indicated it has face validity and content validity.
