Data journey map: a process for co-creating data requirements for health care artificial intelligence.

The Caribbean small island developing states have limited resources for comprehensive health care provision and are facing an increasing burden of noncommunicable diseases which is driven by an aging regional population. Artificial intelligence (AI) and other digital technologies offer promise for contributing to health care efficiencies, but themselves are dependent on the availability and accessibility of accurate health care data. A regional shortfall in data professionals continues to hamper legislative recognition and promotion of increased data production in Caribbean countries.

Mining social media data to inform public health policies: a sentiment analysis case study.

In the face of growing health challenges, nontraditional sources of data, such as open data, have the potential to transform how decisions are made and used to inform public health policies. Focusing on the COVID-19 pandemic, this article presents a case study employing sentiment analysis on unstructured social media data from Twitter (now X) to gauge public sentiment regarding pandemic-related restrictions. Our study aims to uncover and analyze Jamaican citizens' emotions and opinions surrounding COVID-19 restrictions following an outbreak at a call center in April 2020.

Sport-Related Injury and Performance Enhancing Substance Use by Young Athletes.

Background: Legal performance enhancing substance (PES) use is increasing in young athletes and may lead to banned PES use. This study examines legal PES use and consideration of banned PES use in young athletes with a season-ending injury (SEI) compared to young athletes with non-SEI/no previous injury.

Hypothesis: Young athletes sustaining SEI or concussions have increased odds of reporting legal PES use and consideration of banned PES use compared with non-SEI or no injury.

Acute Perioperative Pain Management of the Orthopaedic Patient: Guidance for Operationalizing Evidence Into Practice.

Orthopaedic surgery often results in pain, with less than half of patients reporting adequate relief. Unrelieved acute pain occurring after surgery increases the risk of negative sequelae, including delayed healing, increased morbidity, pulmonary complications, limited rehabilitation participation, anxiety, depression, increased length of stay, prolonged duration of opioid use, and the development of chronic pain. Interventions that are individualized, evidence-informed, and applied within an ethical framework improve healthcare delivery for patients, clinicians, and healthcare organizations.

Sport specialisation and performance-enhancing substance use by young athletes.

Objectives: To investigate the association of reported legal performance enhancing substance (PES) use and consideration of banned PES use among sport-specialised and non-sport-specialised young athletes.

Methods And Design: Cross-sectional study of 1049 young athletes enrolled in an injury prevention programme from 2013 to 2020. We used logistic regression modelling to determine the independent association between sports specialisation.

Position Statement: Acute Perioperative Pain Management Among Patients Undergoing Orthopedic Surgery by the American Society for Pain Management Nursing and The National Association of Orthopaedic Nurses.

Patients undergoing elective orthopaedic surgery may experience pain that is acute, chronic or a combination of the two, with less than half of all surgical patients reporting adequate pain relief. The National Association of Orthopaedic Nurses (NAON) and the American Society for Pain Management Nursing (ASPMN) have partnered to provide evidence-informed guidance to empower nurses to employ effective pain management. Understanding and applying ethical, evidence-informed, patient-focused, interprofessional interventions will improve outcomes for patients, clinicians, and healthcare organizations.

Nurses' Ability to Recognize and Prevent Opioid-Induced Respiratory Depression: An Evidenced-Based Practice Project.

Opioids are the primary therapy for acute postoperative pain, despite being associated with opioid-induced respiratory depression (OIRD). The purpose of this study was to improve nurses' knowledge, confidence, and ability to recognize, prevent, and treat OIRD in postoperative inpatients and evaluate the feasibility of using the Pasero Opioid-Induced Sedation Scale (POSS). Registered nurses completed three tools: (1) an Opioid Knowledge Self-Assessment, which was administered pre- and post-education; (2) a Confidence Scale, which was administered pre- and post-education; and (3) a POSS Perceptions and Usability Scale that was administered post-education.

Radionuclide resuspension across ecosystems and environmental disturbances.

Exposure assessment from radionuclides and other soil-bound contaminants often requires quantifying the amount of contaminant resuspended in the air. Rates and controlling factors of radionuclide resuspension and wind erosion of soil are clearly related but have largely been studied separately. Here, we review both and then integrate wind erosion measurements with the radiological resuspension paradigm to provide better estimates of resuspension factors across a broad range of ecosystems and environmental conditions.

The regulation of p53, p38 MAPK, JNK and XBP-1s by sphingosine kinases in human embryonic kidney cells.

Since inhibitors of sphingosine kinases (SK1, SK2) have been shown to induce p53-mediated cell death, we have further investigated their role in regulating p53, stress activated protein kinases and XBP-1s in HEK293T cells. Treatment of these cells with the sphingosine kinase inhibitor, SKi, which fails to induce apoptosis, promoted the conversion of p53 into two proteins with molecular masses of 63 and 90 kDa, and which was enhanced by over-expression of ubiquitin. The SKi induced conversion of p53 to p63/p90 was also enhanced by siRNA knockdown of SK1, but not SK2 or dihydroceramide desaturase (Degs1), suggesting that SK1 is a negative regulator of this process.

Validation Tests of Resuspension Models for a Finite and Infinite Site.

Dose assessment for deposited radionuclides often requires estimates of air concentrations that are derived from measured soil concentrations. For this, dose assessors typically use literature resuspension values that, while empirically based, can vary by orders of magnitude making it difficult to provide accurate dose estimates. Despite the complexities of the physical processes involved in resuspension, the models generally used for dose assessment are relatively simplistic and rarely are the models validated for a specific site, thus making prediction of air concentrations or airborne emissions highly uncertain.

Native and Polyubiquitinated Forms of Dihydroceramide Desaturase Are Differentially Linked to Human Embryonic Kidney Cell Survival.

There is controversy concerning the role of dihydroceramide desaturase (Degs1) in regulating cell survival, with studies showing that it can both promote and protect against apoptosis. We have therefore investigated the molecular basis for these opposing roles of Degs1. Treatment of HEK293T cells with the sphingosine kinase inhibitor SKi [2-(-hydroxyanilino)-4-(-chlorophenyl)thiazole] or fenretinide, but not the Degs1 inhibitor GT11 {-[(1,2)-2-hydroxy-1-hydroxymethyl-2-(2-tridecyl-1-cyclopropenyl)ethyl]octan-amide}, induced the polyubiquitination of Degs1 ( = 40 to 140 kDa) via a mechanism involving oxidative stress, p38 mitogen-activated protein kinase (MAPK), and Mdm2 (E3 ligase).

Discovery of Indole Derivatives as Novel and Potent Dengue Virus Inhibitors.

3-Acyl-indole derivative 1 was identified as a novel dengue virus (DENV) inhibitor from a DENV serotype 2 (DENV-2) phenotypic antiviral screen. Extensive SAR studies led to the discovery of new derivatives with improved DENV-2 potency as well as activity in nanomolar to micromolar range against the other DENV serotypes. In addition to the potency, physicochemical properties and metabolic stability in rat and human microsomes were improved during the optimization process.

Gamma-Ray Dose From an Overhead Plume.

Standard plume models can underestimate the gamma-ray dose when most of the radioactive material is above the heads of the receptors. Typically, a model is used to calculate the air concentration at the height of the receptor, and the dose is calculated by multiplying the air concentration by a concentration-to-dose conversion factor. Models indicate that if the plume is emitted from a stack during stable atmospheric conditions, the lower edges of the plume may not reach the ground, in which case both the ground-level concentration and the dose are usually reported as zero.

Accuracy of Cloudshine Gamma Dose Calculations in the CAP-88 Dispersion Model.

The U.S. Environmental Protection Agency dispersion model, CAP-88, calculates ground-level dose using the ground-level concentration and the semi-infinite cloud approximation.

Effect of sphingosine kinase modulators on interleukin-1β release, sphingosine 1-phosphate receptor 1 expression and experimental autoimmune encephalomyelitis.

Background And Purpose: The sphingosine analogue, FTY720 (Gilenya ), alleviates clinical disease progression in multiple sclerosis. Here, we variously assessed the effects of an azide analogue of (S)-FTY720 vinylphosphonate (compound 5; a sphingosine kinase 1 activator), (R)-FTY720 methyl ether (ROMe, a sphingosine kinase 2 inhibitor) and RB-020 (a sphingosine kinase 1 inhibitor and sphingosine kinase 2 substrate) on IL-1β formation, sphingosine 1-phosphate levels and expression of S1P receptors. We also assessed the effect of compound 5 and ROMe in an experimental autoimmune encephalomyelitis (EAE) model in mice.

Postoperative respiratory failure necessitating transfer to the intensive care unit in orthopedic surgery patients: risk factors, costs, and outcomes.

Background: Postoperative pulmonary complications in orthopedic surgery patients have been associated with worse clinical outcomes. Identifying patients with respiratory risk factors requiring enhanced monitoring and management modifications is an important part of postoperative care. Patients with unanticipated respiratory decompensation requiring transfer to the intensive care unit (ICU) have not been studied in sufficient detail.

Proteasomal degradation of sphingosine kinase 1 and inhibition of dihydroceramide desaturase by the sphingosine kinase inhibitors, SKi or ABC294640, induces growth arrest in androgen-independent LNCaP-AI prostate cancer cells.

Sphingosine kinases (two isoforms termed SK1 and SK2) catalyse the formation of the bioactive lipid sphingosine 1-phosphate. We demonstrate here that the SK2 inhibitor, ABC294640 (3-(4-chlorophenyl)-adamantane-1-carboxylic acid (pyridin-4-ylmethyl)amide) or the SK1/SK2 inhibitor, SKi (2-(p-hydroxyanilino)-4-(p-chlorophenyl)thiazole)) induce the proteasomal degradation of SK1a (Mr = 42 kDa) and inhibit DNA synthesis in androgen-independent LNCaP-AI prostate cancer cells. These effects are recapitulated by the dihydroceramide desaturase (Des1) inhibitor, fenretinide.

Role of sphingosine 1-phosphate receptors, sphingosine kinases and sphingosine in cancer and inflammation.

Sphingosine kinase (there are two isoforms, SK1 and SK2) catalyses the formation of sphingosine 1-phosphate (S1P), a bioactive lipid that can be released from cells to activate a family of G protein-coupled receptors, termed S1P1-5. In addition, S1P can bind to intracellular target proteins, such as HDAC1/2, to induce cell responses. There is increasing evidence of a role for S1P receptors (e.

Desmoplastic infantile ganglioglioma with associated giant aneurysm—case report.

Desmoplastic infantile ganglioglioma (DIG) and supratentorial giant cerebral aneurysm are each extremely rare entities in infants. Here, we present the case of an 8-day old boy who had both of these conditions concurrently. To our knowledge, there is no previous case reported of a patient with coexisting DIG and giant aneurysm.

2-(2-oxo-morpholin-3-yl)-acetamide derivatives as broad-spectrum antifungal agents.

From a fungicidal screen, we identified 2-(2-oxo-morpholin-3-yl)-acetamide derivatives as fungicidal agents against Candida species, additionally characterized by antifungal activity against Aspergillus species. However, development of this series was hampered by low plasmatic stability. Introduction of a gem-dimethyl on the 6-position of the morpholin-2-one core led to considerable improvement in plasmatic stability while maintaining in vitro antifungal activity.

Addressing nuclides not in the CAP88-PC Version-3 library.

Versions of the computer program, CAP88, are widely used to calculate the radiological doses from radionuclides emitted into the air. CAP88-PC Version-3 includes an extensive library of radionuclides, but there are many more that are not included. Surrogates are often used to substitute for nuclides not in the library, though the results are usually overestimates.

Validation test for CAP88 predictions of tritium dispersion at Los Alamos National Laboratory.

Gaussian plume models, such as CAP88, are used regularly for estimating downwind concentrations from stack emissions. At many facilities, the U.S.

Operational experience of continuous air monitoring of smoke for ²³⁹Pu during a wildfire.

Smoke from a wildfire in northern New Mexico that moved along the border of the Los Alamos National Laboratory (LANL) was monitored for ²³⁹Pu in the event that the fire might cross into LANL property containing locations with low, but greater than background, levels of ²³⁹Pu and other alpha-emitting radionuclides. Three Environmental Continuous Air Monitors (ECAMs) in operation at LANL at the time of the fire provided near real-time measurements of the ²³⁹Pu in the smoke. Sampling data from routine measurements of PM-10 and PM-2.
