Protocol for a randomized controlled trial with a stepped care approach, utilizing PrEP navigation with and without contingency management, for transgender women and sexual minority men with a substance use disorder: Assistance Services Knowledge-PrEP (A.S.K.-PrEP).

Background: In the United States, most (~ 70%) annual newly diagnosed HIV infections are among substance-using sexual minority men (SMM) and gender minority transgender women (trans women). Trans women and SMM are more likely to report or be diagnosed with a substance use disorder (SUD) than their cisgender or heterosexual counterparts and the presence of an SUD substantially increases the risk of HIV infection in both groups. Although Pre-Exposure Prophylaxis (PrEP) is highly effective, initiation, adherence, and persistence are exclusively behavioral outcomes; thus, the biomedical benefits of PrEP are abrogated by substance use.

Cost of start-up activities to implement a community-level opioid overdose reduction intervention in the HEALing Communities Study.

Background: Communities That HEAL (CTH) is a novel, data-driven community-engaged intervention designed to reduce opioid overdose deaths by increasing community engagement, adoption of an integrated set of evidence-based practices, and delivering a communications campaign across healthcare, behavioral-health, criminal-legal, and other community-based settings. The implementation of such a complex initiative requires up-front investments of time and other expenditures (i.e.

Estimated Costs and Outcomes Associated With Use and Nonuse of Medications for Opioid Use Disorder During Incarceration and at Release in Massachusetts.

Importance: Most prisons and jails in the US discontinue medications for opioid use disorder (MOUD) upon incarceration and do not initiate MOUD prior to release.

Objective: To model the association of MOUD access during incarceration and at release with population-level overdose mortality and OUD-related treatment costs in Massachusetts.

Design, Setting, And Participants: This economic evaluation used simulation modeling and cost-effectiveness with costs and quality-adjusted life-years (QALYs) discounted at 3% to compare MOUD treatment strategies in a corrections cohort and an open cohort representing individuals with OUD in Massachusetts.

Multi-Dimensional Antioxidant Screening of Selected Australian Native Plants and Putative Annotation of Active Compounds.

and are native plants of Australia, which were used by the First Peoples for medicinal purposes. In this study, 70% aqueous ethanol crude extracts were prepared from bark and leaves, leaves and leaves, and partitioned via sequential extraction with -hexane, dichloromethane (DCM), ethyl acetate and ethanol. The crude extracts and fractions were screened for antioxidant activity using a novel, high-throughput lipid-based antioxidant assay, as well as the aqueous ABTS (2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid)) assay and the Folin-Ciocalteu test for total phenols.

Budget impact tool for the incorporation of medications for opioid use disorder into jail/prison facilities.

Background: Given the personal and public consequences of untreated/undertreated OUD among persons involved in the justice system, an increasing number of jails and prisons are incorporating medication for opioid use disorder (MOUD) into their system. Estimating the costs of implementing and sustaining a particular MOUD program is vital to detention facilities, which typically face modest, fixed health care budgets. We developed a customizable budget impact tool to estimate the implementation and sustainment costs of numerous MOUD delivery models for detention facilities.

Health economic analyses of the justice community opioid innovation network (JCOIN).

The Justice Community Opioid Innovation Network (JCOIN) will generate real-world evidence to address the unique needs of people with opioid use disorder (OUD) in justice settings. Evidence regarding the economic value of OUD interventions in justice populations is limited. Moreover, the variation in economic study designs is a barrier to defining specific interventions as broadly cost-effective.

A clinical protocol of a comparative effectiveness trial of extended-release naltrexone versus extended-release buprenorphine with individuals leaving jail.

This study is a randomized, open label, controlled trial of extended-release buprenorphine (XR-B; BRIXADI™ formulation) versus extended-release naltrexone (XR-NTX) in Maryland jails. A 7-site, open-label, equivalence design will randomly assign 240 adults with a history of opioid use disorder (OUD), stratified by gender and jail, who are nearing release to one of two treatment arms: 1) XR-B in jail or 2) XR-NTX in jail, both followed by 6 monthly injections postrelease at a community treatment program. The primary aim is to determine the rate of pharmacotherapy adherence (number of monthly injections received) of XR-B compared to XR-NTX.

Health-related quality of life and opioid use disorder pharmacotherapy: A secondary analysis of a clinical trial.

Objective: To examine the health-related quality-of-life (HRQoL) of persons with opioid use disorder (OUD) seeking treatment in an inpatient detoxification or short-term residential setting; continuing treatment as outpatients.

Methods: We conducted a secondary analysis of data from a clinical trial (N = 508) where participants were randomized to extended-release naltrexone or buprenorphine-naloxone for the prevention of opioid relapse. We used a generalized structural equation regression mixture model to identify associations of HRQoL (EQ-5D) trajectories, including latent characteristics, over the 24-week trial and 36-week follow-up period, among participants who reported HRQoL beyond baseline.

A Novel Mechanism for Activation of Myosin Regulatory Light Chain by Protein Kinase C-Delta in .

Myosin is an essential motor protein, which in muscle is comprised of two molecules each of myosin heavy-chain (MHC), the essential or alkali myosin light-chain 1 (MLC1), and the regulatory myosin light-chain 2 (MLC2). It has been shown previously that MLC2 phosphorylation at two canonical serine residues is essential for proper flight muscle function in ; however, MLC2 is also phosphorylated at additional residues for which the mechanism and functional significance is not known. We found that a hypomorphic allele of causes a flightless phenotype; therefore, we hypothesized that PKCδ phosphorylates MLC2.

Bulk and compound-specific stable isotope ratio analysis for authenticity testing of organically grown tomatoes.

Until now, there has been a lack of analytical methods that can reliably verify the authenticity of organically grown plants and derived organic food products. In this study, stable isotope ratio analysis of hydrogen (H, δH), carbon (C, δC), nitrogen (N, δN), oxygen (O, δO) and sulfur (S, δS) was conducted along the tomato passata production process using organic and conventionally grown tomatoes from two Italian regions over two years. A gas chromatography-combustion-isotope ratio mass spectrometry (GC-C-IRMS) based method was developed and applied for analysis of C and N isotope ratios in amino acids derived from tomatoes.

Postgraduate clinical physiotherapy education in acute hospitals: a cohort study.

: Junior physiotherapists require satisfactory clinical skills to work effectively within the acute hospital setting for service quality and consistency. : To investigate the effects of stream-specific clinical training on junior physiotherapist self-efficacy, self-rated confidence, and self-rated ability to work independently during weekend shifts. : Prospective cohort study.

Differentiation of wood-derived vanillin from synthetic vanillin in distillates using gas chromatography/combustion/isotope ratio mass spectrometry for δ C analysis.

Rationale: Typical storage in oak barrels releases in distillates different degradation products such as vanillin, which play an important role in flavour and aroma. The addition of vanillin, as well as other aroma compounds, of different origin is prohibited by European laws. As vanillin samples from different sources have different δ C values, the δ C value could be used to determine whether the vanillin is authentic (lignin-derived), or if it has been added from another source (e.

Dietary Effects on Stable Carbon Isotope Composition of Fatty Acids in Polar and Neutral Fractions of Intramuscular Fat of Lambs.

In this study we measured δC values of the main fatty acids (FA) present in neutral and polar intramuscular lipids of meat samples from 24 lambs, fed with four different diets supplemented with sunflower and linseed oil and the tanniferous shrub Cistus ladanifer L. The objective was to understand if the increase in intramuscular fat observed in lambs fed simultaneously C. ladanifer and oil was explained mostly by incorporation of diet derived FA or by increased de novo FA synthesis.

Recommendations and Standardization of Biomarker Quantification Using NMR-Based Metabolomics with Particular Focus on Urinary Analysis.

NMR-based metabolomics has shown considerable promise in disease diagnosis and biomarker discovery because it allows one to nondestructively identify and quantify large numbers of novel metabolite biomarkers in both biofluids and tissues. Precise metabolite quantification is a prerequisite to move any chemical biomarker or biomarker panel from the lab to the clinic. Among the biofluids commonly used for disease diagnosis and prognosis, urine has several advantages.

Standardizing the experimental conditions for using urine in NMR-based metabolomic studies with a particular focus on diagnostic studies: a review.

The metabolic composition of human biofluids can provide important diagnostic and prognostic information. Among the biofluids most commonly analyzed in metabolomic studies, urine appears to be particularly useful. It is abundant, readily available, easily stored and can be collected by simple, noninvasive techniques.

Health-Related Quality of Life in Australasian Survivors of H1N1 Influenza Undergoing Mechanical Ventilation. A Multicenter Cohort Study.

Rationale: Patients surviving acute respiratory distress syndrome suffer decrements in physical function and health-related quality of life (HR-QoL); however, it is unclear whether HR-QoL is disproportionately affected in those with H1N1 influenza.

Objectives: The objective was to compare the HR-QoL of patients with a diagnosis of H1N1 influenza who were mechanically ventilated, 12 months after intensive care unit (ICU) discharge with healthy population data and ICU survivor data.

Methods: A prospective, observational, binational, multicenter cohort study was conducted in 11 ICUs in Australia and New Zealand during June-September 2009.

Early mobilization on continuous renal replacement therapy is safe and may improve filter life.

Introduction: Despite studies demonstrating benefit, patients with femoral vascular catheters placed for continuous renal replacement therapy are frequently restricted from mobilization. No researchers have reported filter pressures during mobilization, and it is unknown whether mobilization is safe or affects filter lifespan. Our objective in this study was to test the safety and feasibility of mobilization in this population.

Unsupportive partner behaviors, social-cognitive processing, and psychological outcomes in couples coping with early stage breast cancer.

This study examined associations between partner unsupportive behaviors, social and cognitive processing, and adaptation in patients and their spouses using a dyadic and interdependent analytic approach. Women with early stage breast cancer (N = 330) and their spouses completed measures of partner unsupportive behavior, maladaptive social (holding back sharing concerns) and cognitive processing (mental disengagement and behavioral disengagement), and global well-being and cancer distress. Results indicated that both individuals' reports of unsupportive partner behavior were associated with their own holding back and their partners' holding back.

Assessment of some Australian red wines for price, phenolic content, antioxidant activity, and vintage in relation to functional food prospects.

Unlabelled: Twenty-three Cabernet Sauvignon wines from the Mudgee region and thirty-two Shiraz wines from the Hunter Valley region were analyzed for phenolic content and antioxidant activity. Concentrations of (+)-catechin, quercetin, and transresveratrol, total phenolic content, and DPPH antioxidant activity varied considerably, both within and between varieties. Individual phenols, total phenols, and antioxidant activity were correlated with price and vintage.

Total phenolic content, antioxidant activity, and cross-cultural consumer rejection threshold in white and red wines functionally enhanced with catechin-rich extracts.

White and red wines spiked with catechin-rich green tea extract and grape seed extract were assessed for phenolic content, antioxidant activity, and cross-cultural consumer rejection thresholds in relation to wine as a functional food. Health functionality is an important factor in functional foods, and spiking pure compounds or plant extracts is an effective method to increase or control functionality. The total phenolic content and antioxidant activity were measured in wines spiked to different extract concentrations, namely, control and 50, 100, 200, 400, and 800 mg/L, to confirm the dose-response curves in both white and red wines.

Delayed salicylate toxicity with undetectable initial levels after large-dose aspirin ingestion.

Aspirin (acetylsalicylic acid), the most commonly used medicinal salicylate, is an antiinflammatory, antipyretic, antirheumatic, and analgesic agent. In 2005, according to the Toxic Exposures Survey from the American Association of Poison Control Centers' National Poisoning and Exposure Database, there were more than 20,000 reported aspirin and nonaspirin salicylate exposures, 64% of which required treatment in a health care facility. Of these exposures, 50% were reported as intentional overdoses and 60 patients died.
