Hepatic lipogenesis is fine-tuned by mechanistic target of rapamycin (mTOR) signaling.A new federal agency-approved last month by the United States Congress-is already off to a rocky start. The Advanced Research Projects Agency for Health (ARPA-H), proposed by President Biden in 2021, aims to tackle the most intractable biomedical problems by funding innovative, high-risk, high-reward research and swiftly turning discoveries into treatments and cures. But Congress gave the agency a much smaller budget than sought by the administration-$ 1 billion over 3 years, a fraction of the $6.5 billion requested. And as happens whenever there is new money and a new federal agency, a political scrum has erupted over who should control ARPA-H. It is now expected to answer to both the National Institutes of Health (NIH) and the Department of Health and Human Services (HHS). If it is to deliver on its mission, ARPA-H needs to be an autonomous entity that approaches biomedical research in a way never done before by the federal government. The stakes are high If ARPA-H fails to produce new clinical advances relatively quickly, it will erode trust in US science. It's time for clear thinking and action about what it will take to make ARPA-H successful.The U.S. Environmental Protection Agency (EPA) modified its guidance on determining "method detection limits" (MDL) in 2017. The recommended procedures have not yet been applied to the analyses routinely done on filter samples for EPA's Chemical Speciation Network (CSN). This paper applies the new EPA procedure for estimating MDL to Energy Dispersive X-Ray Fluorescence (EDXRF) analysis of atmospheric aerosol samples collected on filters. The procedure involves estimating MDL by two approaches - statistical distributions of unloaded blank sample measurements and lightly loaded, spiked samples - and sets the MDL as the maximum of these two approaches. Spiked samples at low concentrations were developed using an aerosol deposition chamber to follow this approach. The MDL procedure was initially conducted on one EDXRF instrument, and the spike-based MDL was found to be higher than blank-based MDL for 28 of the 31 elements. The blank-based MDL was higher than the spike-based MDL for Si, K and Fe, which are common contaminants present in filter raw media or arising from EDXRF hardware. The annual verification performed using five EDXRF analyzers demonstrated that the MDL estimated following the EPA procedure was stable over time and analyzers for all elements except K, which yielded a higher MDL.Implications Lightly loaded reference materials (RM) were developed for Energy Dispersive X-ray Fluorescence (EDXRF) measurements of elemental concentrations in filter-based particulate matter samples using a novel aerosol generation chamber. These RM were then used to estimate method detection limits (MDL) following U.S. Environmental Protection Agency guidance. These new MDL estimates were compared to alternative estimates and, for most elements, are higher. Our work provides EDXRF users with MDL estimates for each element and an assessment of different MDL estimation approaches.Background The manual resuscitator device is the most common method of ventilating patients with respiratory failure, either with a facemask, or with an advanced airway such as an endotracheal tube (ETT). Barotrauma and gastric inflation from excessive ventilation volumes or pressure are concerning complications. Ventilating adult patients with pediatric manual resuscitator may provide more lung-protective tidal volumes based on stationary patient simulations. However, use of a pediatric manual resuscitator in mobile simulations contradictorily generates inadequate tidal volumes.Methods Sixty-two emergency medical services (EMS) clinicians in a moving ambulance ventilated a manikin using pediatric and adult manual resuscitators in conjunction with oral-pharyngeal airway, i-gel, King LTS-D, or an endotracheal tube.Results Oral-pharyngeal airway data were discarded due to EMS clinician inability to produce measurable tidal volumes. Mean ventilation volumes using the pediatric manual resuscitator were inadequate compared to those with the adult manual resuscitator on all other airway devices. In addition, i-gel, King LTS-D, and endotracheal tube volumes were statistically comparable. Paramedics ventilated larger volumes than emergency medical technicians.Conclusions Using a pediatric manual resuscitator on adult patients is not supported by our findings.Medication treatment for opioid use disorder (MOUD) is an effective evidence-based therapy for decreasing opioid-related adverse outcomes. Effective strategies for retaining persons on MOUD, an essential step to improving outcomes, are needed as roughly half of all persons initiating MOUD discontinue within a year. Data science may be valuable and promising for improving MOUD retention by using "big data" (e.g., electronic health record data, claims data mobile/sensor data, social media data) and specific machine learning techniques (e.g., predictive modeling, natural language processing, reinforcement learning) to individualize patient care. Maximizing the utility of data science to improve MOUD retention requires a three-pronged approach (1) increasing funding for data science research for OUD, (2) integrating data from multiple sources including treatment for OUD and general medical care as well as data not specific to medical care (e.g., mobile, sensor, and social media data), and (3) applying multiple data science approaches with integrated big data to provide insights and optimize advances in the OUD and overall addiction fields.
The purpose of the present study was to verify the acute effects of blood pressure and blood glucose after two sessions of combined exercise sessions performed at two levels of intensity in trained individuals with cardiovascular risk factors.

Eighteen individuals (66.22±8.61years) of both sexes (6 women/12 men) with cardiovascular risk factors performed two sessions of combined exercises at different levels of intensity moderate (MOD) and high (HI). To control the intensity of the aerobic training, the Borg Rating of Perceived Exertion (RPE) Scale was used. For the strength training, the maximum number of repetitions was carried out within a predetermined duration of sets. Blood pressure and blood glucose measurements were collected before and 20minutes after the sessions. The data were analyzed using Generalized Estimating Equations, α 5%.

Reductions were observed in systolic blood pressure (MOD - Δ=-4.95mmHg; HI - Δ=-3.31mmHg) and blood glucose (MOD - Δ=-16.06 mg/dL; HI - Δ=-29.45 mg/dL) after the two sessions, with no difference between sessions. Diastolic blood pressure did not change (
<.05).

Combined exercises sessions of moderate or high intensity can promote an acute reduction in systolic blood pressure and glycemia in individuals with cardiovascular risk factors.

Prehospital initiation of buprenorphine treatment for Opioid Use Disorder (OUD) by paramedics is an emerging potential intervention to reach patients at greatest risk for opioid-related death. Emergency medical services (EMS) patients who are at high risk for overdose deaths may never engage in treatment as they frequently refuse transport to the hospital after naloxone reversal. The potentially important role of EMS as the initiator for medication for opioid use disorder (MOUD) in the most high-risk patients has not been well described.

This project relies on four interventions a public access naloxone distribution program, an electronic trigger and data sharing program, an "Overdose Receiving Center," and a paramedic-initiated buprenorphine treatment. Oxyphenisatin purchase For the final intervention, paramedics followed a protocol-based pilot that had an EMS physician consultation prior to administration.

There were 36 patients enrolled in the trial study in the first year who received buprenorphine. Of those patients receiving buprenorphine, only one patient signed out against medical advice on scene. All other patients were transported to an emergency department and their clinical outcome and 7 and 30 day follow ups were determined by the substance use navigator (SUN). Thirty-six of 36 patients had follow up data obtained in the short term and none experienced any precipitated withdrawal or other adverse outcomes. Patients had a 50% (18/36) rate of treatment retention at 7 days and 36% (14/36) were in treatment at 30 days.

In this small pilot project, paramedic-initiated buprenorphine in the setting of data sharing and linkage with treatment appears to be a safe intervention with a high rate of ongoing outpatient treatment for risk of fatal opioid overdoses.

Presentation is usually similar to that of breast cancer, with a painless palpable mass. This report describes a unique case of a 13 cm breast lymphoma. The patient is a 74 year old female who presented to clinic with a right breast mass that has been present since the 1970s. She had previously undergone multiple excisions of lesions on both breasts, always with benign pathology. In 2017, screening mammogram revealed a suspicious lesion in the right upper outer breast with associated axillary lymphadenopathy. She was lost to follow up but presented again after the mass significantly grew in size over several months. Mammography showed a large 13 x 8.7 cm lobulated mass. Biopsy of the lesion revealed diffuse large B-cell lymphoma. Treatment for this patient will begin with chemotherapy.
To evaluate the usability and use of human factors (HF)-based clinical decision support (CDS) implemented in the emergency department (ED).

Clinical decision support can improve patient safety; however, the acceptance and use of CDS has faced challenges. Following a human-centered design process, we designed a CDS to support pulmonary embolism (PE) diagnosis in the ED. We demonstrated high usability of the CDS during scenario-based usability testing. We implemented the HF-based CDS in one ED in December 2018.

We conducted a survey of ED physicians to evaluate the usability and use of the HF-based CDS. We distributed the survey via Qualtrics, a web-based survey platform. We compared the computer system usability questionnaire scores of the CDS between those collected in the usability testing to use of the CDS in the real environment. We asked physicians about their acceptance and use of the CDS, barriers to using the CDS, and areas for improvement.

Forty-seven physicians (56%) completed the survey. Physicians agreed that diagnosing PE is a major problem and risk scores can support the PE diagnostic process. Usability of the CDS was reported as high, both in the experimental setting and the real clinical setting. However, use of the CDS was low. We identified several barriers to the CDS use in the clinical environment, in particular a lack of workflow integration.

Design of CDS should be a continuous process and focus on the technology's usability in the context of the broad work system and clinician workflow.
