TimelinePTC: Development of a unified interface for pathways to care collection, visualization, and collaboration in first episode psychosis.

This paper presents TimelinePTC, a web-based tool developed to improve the collection and analysis of Pathways to Care (PTC) data in first episode psychosis (FEP) research. Accurately measuring the duration of untreated psychosis (DUP) is essential for effective FEP treatment, requiring detailed understanding of the patient's journey to care. However, traditional PTC data collection methods, mainly manual and paper-based, are time-consuming and often fail to capture the full complexity of care pathways.

Accelerating Medicines Partnership® Schizophrenia (AMP® SCZ): Rationale and Study Design of the Largest Global Prospective Cohort Study of Clinical High Risk for Psychosis.

This article describes the rationale, aims, and methodology of the Accelerating Medicines Partnership® Schizophrenia (AMP® SCZ). This is the largest international collaboration to date that will develop algorithms to predict trajectories and outcomes of individuals at clinical high risk (CHR) for psychosis and to advance the development and use of novel pharmacological interventions for CHR individuals. We present a description of the participating research networks and the data processing analysis and coordination center, their processes for data harmonization across 43 sites from 13 participating countries (recruitment across North America, Australia, Europe, Asia, and South America), data flow and quality assessment processes, data analyses, and the transfer of data to the National Institute of Mental Health (NIMH) Data Archive (NDA) for use by the research community.

Adopting a Novel Approach to Prevent and Address Patient Mistreatment of Staff in a Community Mental Health Center.

Verbal mistreatment of staff by patients is common in health care settings. Experiencing or witnessing mistreatment can have harmful psychological impacts, affecting well-being and clinical practice. As part of an effort to become an antiracist organization, an academic community mental health center based in Connecticut developed an initiative to address verbal mistreatment.

High-throughput mass spectrometry analysis using immediate drop-on-demand technology coupled with an open port sampling interface.

Rationale: The sampling throughput of immediate drop-on-demand technology (I.DOT) coupled with an open port sampling interface (OPSI) is limited by software communication. To enable much-needed high-throughput mass spectrometry (MS) analysis capabilities, a novel software was developed that allows for flexible sample selection from a 96-well plate and for maximized analysis throughput using I.

Rapid Droplet Sampling Interface for Low-Volume, High-Throughput Mass Spectrometry Analysis.

Here, we present a rapid droplet sampling interface (RDSI) electrospray ionization mass spectrometry (ESI-MS) system as a high-throughput, low-volume, noncontact, and minimal-carryover approach for characterization of liquids. Liquid characterization was achieved by combining droplet ejection with an open-face microflow capillary with a 2.5 μL/min continuous flow of carrier solvent.

Structure-Driven Liquid Microjunction Surface-Sampling Probe Mass Spectrometry.

The rhizosphere is the narrow region of soil surrounding the roots of plants that is influenced by root exudates, root secretions, and associated microbial communities. This region is crucial to plant growth and development and plays a critical role in nutrient uptake, disease resistance, and soil transformation. Understanding the function of exogenous compounds in the rhizosphere starts with determining the spatiotemporal distribution of these molecular components.

High-Throughput Characterization and Optimization of Polyamide Hydrolase Activity Using Open Port Sampling Interface Mass Spectrometry.

Enzymatic biodegradation of polymers, such as polyamides (PA), has the potential to cost-effectively reduce plastic waste, but enhancements in degradation efficiency are needed. Engineering enzymes through directed evolution is one pathway toward identification of critical domains needed for improving activity. However, screening such enzymatic libraries (100s-to-1000s of samples) is time-consuming.

Granular analysis of pathways to care and durations of untreated psychosis: A marginal delay model.

Objective: An extensive international literature demonstrates that understanding pathways to care (PTC) is essential for efforts to reduce community Duration of Untreated Psychosis (DUP). However, knowledge from these studies is difficult to translate to new settings. We present a novel approach to characterize and analyze PTC and demonstrate its value for the design and implementation of early detection efforts.

Promoting the Success and Sustainability of Coordinated Specialty Care Teams in Ohio.

Recent COVID-19-related federal legislation has resulted in time-limited increases in Mental Health Block Grant (MHBG) set-aside dollars for coordinated specialty care (CSC) throughout the United States. The state of Ohio has opted to apply these funds to establish a learning health network of Ohio CSC teams, promote efforts to expand access to CSC, and quantify the operating costs and rates of reimbursement from private and public payers for these CSC teams. These efforts may provide other states with a model through which they can apply increased MHBG funds to support the success of their own CSC programs.

Integrating Ambulatory Addiction Consultation Service Into a Community Mental Health Center.

Despite the escalation in substance related overdose mortality-culminating in more than 100,000 deaths in each of the first 2 years of the COVID-19 pandemic-healthcare systems have not kept up with the demands for care among people who use drugs. There remains a significant gap in access to evidence-based treatment. The addiction consult services has served to address this gap, as a critical intervention that engages mostly hospitalized patients and initiate addiction treatment in acute settings, but little is known about addiction consult services in ambulatory settings.

Navigating the digital divide: providing services to people with serious mental illness in a community setting during COVID-19.

Community mental healthcare around the world has been strained as people need more help and experience more barriers to access due to COVID-19. The rapid shift to telehealth services necessitated by the pandemic has made these difficulties even more pronounced. While this transition presented challenges for nearly every healthcare system, it has proven especially difficult for low resource settings such as community health centers.

In Situ Detection of Amino Acids from Bacterial Biofilms and Plant Root Exudates by Liquid Microjunction Surface-Sampling Probe Mass Spectrometry.

The plant rhizosphere is a complex and dynamic chemical environment where the exchange of molecular signals between plants, microbes, and fungi drives the development of the entire biological system. Exogenous compounds in the rhizosphere are known to affect plant-microbe organization, interactions between organisms, and ultimately, growth and survivability. The function of exogenous compounds in the rhizosphere is still under much investigation, specifically with respect to their roles in plant growth and development, the assembly of the associated microbial community, and the spatiotemporal distribution of molecular components.

Risk of deaths due to injuries in travellers: a systematic review.

Background: Annual global travel reached an all-time high of 1.4 billion international tourist visits in 2019. It is estimated that injury accounts for close to 25% of deaths in travellers, most of which are theoretically preventable.

Reducing Delay From Referral to Admission at a U.S. First-Episode Psychosis Service: A Quality Improvement Initiative.

Duration of untreated psychosis (DUP), the period between psychosis onset and entry into care, is a time of great vulnerability. Longer DUP predicts poorer outcomes, and delayed treatment access can limit the effectiveness of coordinated specialty care (CSC) services. This column details one component of a broader early detection campaign, a quality improvement intervention focusing on reducing the delay between confirmation of eligibility and admission to care within a benchmark period of 7 days.

Reducing the Duration of Untreated Psychosis (DUP) in a US Community: A Quasi-Experimental Trial.

Objective: Duration of Untreated Psychosis (DUP) remains unacceptably long and limits effectiveness of care. To determine whether an early detection campaign ("Mindmap") can reduce DUP in a US community setting.

Methods: In this nonrandomized controlled trial, Mindmap targeted the catchment of one specialty first-episode service or FES (STEP, Greater New Haven) from 2015 to 2019, while usual detection efforts continued at a control FES (PREP, Greater Boston).

Hotspots of root-exuded amino acids are created within a rhizosphere-on-a-chip.

The rhizosphere is a challenging ecosystem to study from a systems biology perspective due to its diverse chemical, physical, and biological characteristics. In the past decade, microfluidic platforms ( plant-on-a-chip) have created an alternative way to study whole rhizosphere organisms, like plants and microorganisms, under reduced-complexity conditions. However, in reducing the complexity of the environment, it is possible to inadvertently alter organism phenotype, which biases laboratory data compared to experiments.

Taking the next step: Improving care transitions from a first-episode psychosis service.

Aims: First-episode services (FES) improve outcomes in recent onset psychosis, but there is growing concern about how patients fare after discharge from these time-limited services.

Methods: A quality improvement approach (QI) was used to improve patient engagement in the discharge planning process (disposition), and successful engagement in care 3 months after discharge from the FES (transfer). Data from 144 consecutive discharges over 62 months are presented.

Quantitation of amiodarone and N-desethylamiodarone in single HepG2 cells by single-cell printing-liquid vortex capture-mass spectrometry.

Quantitative measure of a drug and its associated metabolite(s) with single-cell resolution is often limited by sampling throughput or other compromises that limit broad use. Here, we demonstrate the use of single-cell printing-liquid vortex capture-mass spectrometry (SCP-LVC-MS) to quantitatively measure the intracellular concentrations of amiodarone (AMIO) and its metabolite, N-desethylamiodarone (NDEA), from thousands of single cells across several AMIO incubation concentrations ranging from 0 to 10 μM. Concentrations obtained by SCP-LVC-MS were validated through comparison with average assays and traditional measurement of cells in bulk.

Absolute quantitation of propranolol from 200-μm regions of mouse brain and liver thin tissues using laser ablation-dropletProbe-mass spectrometry.

Rationale: The ability to quantify drugs and metabolites in tissue with sub-mm resolution is a challenging but much needed capability in pharmaceutical research. To fill this void, a novel surface sampling approach combining laser ablation with the commercial dropletProbe automated liquid surface sampling system (LA-dropletProbe) was developed and is presented here.

Methods: Parylene C-coated 200 × 200 μm tissue regions of mouse brain and kidney thin tissue sections were analyzed for propranolol by laser ablation of tissue directly into a preformed liquid junction.

Design and Evaluation of a Tethered, Open Port Sampling Interface for Liquid Extraction-Mass Spectrometry Chemical Analysis.

Presented is a tethered, liquid-extraction-sampling interface designed for the mass spectrometric surface sampling/analysis of 3D objects. The tethered, open port sampling interface (TOPSI) incorporates a vacuum line between the sampling probe and ionization source, which enables the ability for an extended, tethered sample transfer line. Herein, several designs of the hand-held TOPSI are presented and evaluated on the basis of the analytical metrics of analyte transport time, peak width, and analyte sensitivity.

Spatially resolved absolute quantitation in thin tissue by mass spectrometry.

Mass spectrometry (MS) has become the de facto tool for routine quantitative analysis of biomolecules. MS is increasingly being used to reveal the spatial distribution of proteins, metabolites, and pharmaceuticals in tissue and interest in this area has led to a number of novel spatially resolved MS technologies. Most spatially resolved MS measurements are qualitative in nature due to a myriad of potential biases, such as sample heterogeneity, sampling artifacts, and ionization effects.
