Piloting a Clinical Decision Support Tool to Identify Patients With Social Needs and Provide Navigation Services and Referral to Community-Based Organizations: Protocol for a Randomized Controlled Trial.

Background: Social needs and social determinants of health (SDOH) significantly outrank medical care when considering the impact on a person's length and quality of life, resulting in poor health outcomes and worsening life expectancy. Integrating social needs and SDOH data along with clinical risk information within operational clinical decision support (CDS) systems built into electronic health records (EHRs) is an effective approach to addressing health-related social needs. To achieve this goal, applied research is needed to develop EHR-integrated CDS tools and closed-loop referral systems and implement and test them in the digital and clinical workflows at health care systems and collaborating community-based organizations (CBOs).

Plastic additives in the ocean: Use of a comprehensive dataset for meta-analysis and method development.

In excess of 13,000 chemicals are added to plastics ('additives') to improve performance, durability, and production of plastic products. They are categorized into numerous chemical classes including flame retardants, light stabilizers, antioxidants, and plasticizers. While research on plastic additives in the marine environment has increased over the past decade, there is a lack of methodological standardization.

How Do Risk Evaluation and Mitigation Strategies Impact Clinical Practice? A National Survey of Physicians.

The US Food and Drug Administration can require risk evaluation and mitigation strategy (REMS) programs for prescription drugs to ensure the benefits of use outweigh the risks. We conducted a national survey of physicians' experiences prescribing eight REMS-covered drugs: (1) ambrisentan; (2) bosentan; (3) clozapine; (4) isotretinoin; (5-7) the multiple myeloma (MM) drugs lenalidomide, pomalidomide, thalidomide; and (8) sodium oxybate. Between May 2022 and January 2023, we surveyed 5,331 physician prescribers of these drugs, and 1,295 (24%) returned surveys (range: 149 for bosentan to 226 for MM drugs).

Arginine vasopressin injection rescues delayed oviposition in mutant female zebrafish.

In zebrafish, estrogens produced in the ovaries via Cyp19a1a activity are required for both sexual differentiation of the ovary during early development as well as maintenance of the ovarian state during adulthood. The importance of Cyp19a1b that is highly expressed in the brain for female reproduction is still under study. We previously reported that female mutant zebrafish have significantly lower brain estradiol levels and impaired spawning behavior characterized by an increased latency to oviposition during dyadic sexual behavior encounters.

Microplastics absent from reef fish in the Marshall Islands: Multistage screening methods reduced false positives.

Island communities, like the Republic of the Marshall Islands (RMI), depend on marine resources for food and economics, so plastic ingestion by those resources is a concern. The gastrointestinal tracts of nine species of reef fish across five trophic groups (97 fish) were examined for plastics >1 mm. Over 2100 putative plastic particles from 72 fish were identified under light microscopy.

Polymer identification of floating derelict fishing gear from O'ahu, Hawai'i.

Discarded fishing gear (DFG) comprises most of the plastic in the North Pacific Ocean and causes environmental and economic losses. Building evidence on the material construction of fishing gear types is critical to develop solutions to reduce DFG amounts and impacts. We forensically assessed the construction and chemical composition of eight different gear types removed as DFG around O'ahu, Hawai'i.

Applying the theory of planned behavior to predict COVID-19 booster vaccination intentions of college students.

The purpose of this study was: (a) to determine COVID-19 vaccination rates among college students, (b) to assess what proportion of college students self-report currently or previously having COVID-19, and (c) to test theory of planned behavior (TPB)-based constructs in predicting the COVID-19 booster vaccination behavioral intentions. A non-experimental, cross-sectional study design was applied. The sample consisted of 288 college students ages 18 years and older.

Mutation of brain aromatase disrupts spawning behavior and reproductive health in female zebrafish.

Aromatase (Cyp19a1) is the steroidogenic enzyme that converts androgens into bioactive estrogens, and hence is in a pivotal position to mediate reproduction and sexual behavior. In teleosts, there are two aromatase paralogs: that is highly expressed in granulosa and Leydig cells in the gonads with critical function in sexual differentiation of the ovary, and that is highly expressed in radial glial cells in the brain with unknown roles in reproduction. mutant zebrafish lines were used to investigate the importance of the paralogs for spawning behavior and offspring survival and early development.

Analysis of financial challenges faced by graduate students in Canada.

Graduate students are vital to the creation of research and innovation in Canada. The National Graduate Student Finance Survey was launched in 2021 by the Ottawa Science Policy Network to investigate the financial realities of Canadian graduate students. Closing in April 2022, the survey received 1305 responses from graduate students representing various geographical locations, years of study, fields of education, and demographic backgrounds.

Green Sea Turtles (Chelonia mydas) Accumulate Heavy Metals Near a Former Skeet Shooting Range in Kailua, O'ahu, Hawai'i.

The present study determined if green sea turtles (Chelonia mydas) in Kailua Bay, Oahu, in the Hawaiian Islands have elevated blood and scute lead (Pb), arsenic (As), and antimony (Sb) concentrations resulting from lead deposition at a historic skeet shooting range. Blood and scute samples were collected and analyzed for Pb, As, and Sb via inductively coupled plasma-mass spectrometry. Prey, water, and sediment samples were also analyzed.

Reproductive roles of the vasopressin/oxytocin neuropeptide family in teleost fishes.

The vertebrate nonapeptide families arginine vasopressin (AVP) and oxytocin (OXT) are considered to have evolved from a single vasopressin-like peptide present in invertebrates and termed arginine vasotocin in early vertebrate evolution. Unprecedented genome sequence availability has more recently allowed new insight into the evolution of nonapeptides and especially their receptor families in the context of whole genome duplications. In bony fish, nonapeptide homologues of AVP termed arginine vasotocin (Avp) and an OXT family peptide (Oxt) originally termed isotocin have been characterized.

Natural variation at the odorant receptor locus is associated with changes in olfactory behaviour.

In insects, many critical olfactory behaviours are mediated by the large odorant receptor () gene family, which determines the response properties of different classes of olfactory receptor neurons (ORNs). While ORN responses are generally conserved within and between species, variant alleles of the locus have previously been shown to alter the response profile of an ORN class called ab3A. These alleles show potential clinal variation, suggesting that selection is acting at this locus.

Use of nest bundles to monitor agrochemical exposure and effects among cavity nesting pollinators.

Cavity nesting bees are proficient and important pollinators that can augment or replace honey bee pollination services for some crops. Relatively little is known about specific pesticide concentrations present in cavity nesting insect reed matrices and associated potential risks to cavity nesting bees. Nesting substrates (Phragmites australis reeds in bundles) were deployed in an agriculturally intensive landscape to evaluate colonization and agrochemical exposure among cavity nesting pollinators over two consecutive field seasons.

Trace Element Concentrations in Blood and Scute Tissues from Wild and Captive Hawaiian Green Sea Turtles (Chelonia mydas).

Sea turtles are exposed to trace elements through water, sediment, and food. Exposure to these elements has been shown to decrease immune function, impair growth, and decrease reproductive output in wildlife. The present study compares trace element concentrations in green turtles in captivity at Sea Life Park Hawaii (n = 6) to wild green turtles in Kapoho Bay, Hawaii, USA (n = 5-7).

Bioaccessibility of antimony and other trace elements from lead shot pellets in a simulated avian gizzard environment.

Many studies have used grit (in the form of lead (Pb) pellets) presence in avian gizzards as an indicator of Pb shot exposure. However, due to nearly complete pellet absorption in gizzards or rapid passage of pellets, the absence of Pb shot presence in a gizzard does not confirm lack of Pb shot exposure. This study provides the basis for an additional technique to identify if elevated tissue Pb concentration is due to Pb shot exposure.

Optimization of sortase A ligation for flexible engineering of complex protein systems.

Engineering and bioconjugation of proteins is a critically valuable tool that can facilitate a wide range of biophysical and structural studies. The ability to orthogonally tag or label a domain within a multidomain protein may be complicated by undesirable side reactions to noninvolved domains. Furthermore, the advantages of segmental (or domain-specific) isotopic labeling for NMR, or deuteration for neutron scattering or diffraction, can be realized by an efficient ligation procedure.

Toxicity of Agrochemicals Among Larval Painted Lady Butterflies (Vanessa cardui).

In the Southern High Plains of the United States, beef cattle feed yards and row crop agriculture are predominant sources of agrochemical usage. Beef cattle feed yards use large quantities of veterinary pharmaceuticals to promote cattle growth and health, along with insecticides to control insect pests, whereas row crop-based agriculture relies on herbicides, fungicides, and insecticides to increase yields. Previous studies have documented the occurrence of agrochemicals beyond feed yard and row crop agriculture boundaries in uncultivated, marginal areas, raising concern that migratory pollinators and pollinators indigenous to the Southern High Plains frequenting these remaining habitat corridors may become exposed to toxic agrochemicals.

Molecular and Functional Evolution at the Odorant Receptor Or22 Locus in Drosophila melanogaster.

Insect odorant receptor (Or) genes determine the responses of sensory neurons that mediate critical behaviors. The Drosophila melanogaster Or22 locus represents an interesting example of molecular evolution, with high levels of sequence divergence and copy number variation between D. melanogaster and other Drosophila species, and a corresponding high level of variability in the responses of the neuron it controls, ab3A.

Using Mouse and Models to Investigate the Mechanistic Links between Diet, Obesity, Type II Diabetes, and Cancer.

Many of the links between diet and cancer are controversial and over simplified. To date, human epidemiological studies consistently reveal that patients who suffer diet-related obesity and/or type II diabetes have an increased risk of cancer, suffer more aggressive cancers, and respond poorly to current therapies. However, the underlying molecular mechanisms that increase cancer risk and decrease the response to cancer therapies in these patients remain largely unknown.

Using Post-discharge Home Visitation to Improve Cultural Sensitivity and Patient-centered Discharge Planning by Internal Medicine Trainees.

Background: Patient-centered discharge planning improves transitional care and health outcomes for vulnerable adults. The HOME Initiative was an educational intervention aiming to improve trainees' patient-centered discharge planning skills.

Methods: Using a quasi-experimental design, 52 internal medicine residents at an academic medical center were randomized to intervention or control in 2014-2015.

Aromatase expression and function in the brain and behavior: A comparison across communication systems in teleosts.

Aromatase (Cyp19a1) is a steroidogenic enzyme that functions to convert aromatizable androgens into bioactive estrogens. The teleost brain is known to have the highest levels of aromatase activity among vertebrates, yet we know relatively little about the function of local estrogen production in teleost behavior. This review compares and contrasts the findings from behavioral studies in the visual, auditory, electrosensory, and olfactory systems, with expression studies in the brain and peripheral nervous system to identify pathways for aromatase effects on teleost behavior.

SHP2 inhibition restores sensitivity in ALK-rearranged non-small-cell lung cancer resistant to ALK inhibitors.

Most anaplastic lymphoma kinase (ALK)-rearranged non-small-cell lung tumors initially respond to small-molecule ALK inhibitors, but drug resistance often develops. Of tumors that develop resistance to highly potent second-generation ALK inhibitors, approximately half harbor resistance mutations in ALK, while the other half have other mechanisms underlying resistance. Members of the latter group often have activation of at least one of several different tyrosine kinases driving resistance.

Two Novel Urban Health Primary Care Residency Tracks That Focus On Community-Level Structural Vulnerabilities.

Background: Although residency programs are well situated for developing a physician workforce with knowledge, skills, and attitudes that incorporate the strengths and reflect the priorities of community organizations, few curricula explicitly do so.

Aim: To develop urban health primary care tracks for internal medicine and combined internal medicine-pediatrics residents.

Setting: Academic hospital, community health center, and community-based organizations.

Pattern of aromatase mRNA expression in the brain of a weakly electric fish, Apteronotus leptorhynchus.

Aromatase is a steroidogenic enzyme involved in the conversion of testosterone into estradiol. Teleosts are unique among vertebrates in possessing two distinct aromatase genes that show different expression patterns within the body. Since the brain is the essential organ underlying the control of behavior, an understanding of the expression pattern of aromatase in the brain can help to identify neural circuits and behaviors that are most likely to be affected by aromatase activity.

Nursing Management of the Patient Undergoing Focused Ultrasound: A New Treatment Option for Essential Tremor.

Essential tremor (ET) is among the most common neurological movement disorders that causes postural or action tremors, with an estimated prevalence nationwide of less than 3% of the population. The incidence of ET increases with age but often affects younger adults and has a familial trait association. Depending on disease progression, ET can cause significant limitations for individuals, in many cases, significantly limiting their ability to perform activities of daily living and occupational responsibilities.
