Implementing Quality Improvement Initiatives Within Community Psychiatry: Challenges and Strategies.

Implementation of quality improvement (QI) initiatives within community mental health settings is crucial to addressing equity-related issues affecting mental health services delivery, including for co-occurring substance use disorders. Given the growing recognition of QI interventions as an effective framework to facilitate structural change within systems of care, it is important to equip mental health providers with the knowledge and ability to execute QI initiatives that are feasible, sustainable, and integrate a health equity lens. To demystify the QI process, we describe the design and methodologies of four fellows' capstone projects conducted during the 2022-2023 academic year at the University of California, San Francisco (UCSF) Public Psychiatry Fellowship at Zuckerberg San Francisco General Hospital and Trauma Center (ZSFG).

A Comparison of Passive Rewarming Systems Following Cold Water Immersion.

Introduction: We studied field rewarming using a typical winter sleeping bag versus two heated hypothermia wrap systems in a semi-realistic lab simulation.

Methods: 10 participants (8 M, 2 F) were cooled to 36.1°C core temperature through 10.

Flow cytometry assay modifications: Recommendations for method validation based on CLSI H62 guidelines.

The Clinical and Laboratory Standards Institute (CLSI) H62-Validation of Assays Performed by Flow Cytometry guideline, released in 2021, provides recommendations for platform workflow and quality system essentials, instrument setup and standardization, assay development and optimization and fit-for-purpose analytical method validation. In addition, CLSI H62 includes some recommendations for the validation strategies after a validated flow cytometric method has been modified. This manuscript builds on those recommendations and discusses the impact of different types of assay modifications on assay performance.

Determining cold strain in cold air: a comparison of two methods of partitional calorimetry to calculate heat storage and debt in cold air with mild hypothermia.

We compared two methods of partitional calorimetry to calculate heat storage and heat debt during cold air (0°C) exposure causing mild core cooling. Twelve participants performed a 5 min baseline in thermoneutral conditions (∼22.0°C, ∼50% relative humidity) followed by cold air exposure (∼0°C) until rectal temperature was reduced by ∆-0.

Outcomes of Human Leukocyte Antigen-Matched Related Donor and Haploidentical Allogeneic Hematopoietic Cell Transplantation Recipients by Immune Profiles of Recipients and Donors.

Haploidentical (Haplo) allogeneic HCTs (alloHCT) have been used more frequently over the last decade as survival is similar to HLA-matched related donor (MRD) alloHCTs. We aimed to identify donor and recipient immune signatures before alloHCT that are associated with clinically meaningful outcomes in MRD vs Haplo alloHCT recipients. This retrospective cohort study of 165 MRD (n = 132) and Haplo (n = 33) alloHCT recipients and their related donors between 2007-2019 with paired peripheral blood samples immunophenotyped for T-cell, B-cell, NK cell and dendritic cell (DC) subsets.

T Cell Exhaustion Markers in Multiple Myeloma Patients are Lower After Physical Activity Intervention.

Purpose: There is compelling evidence that CD4 and CD8T cells are dysfunctional in multiple myeloma, compromising their ability to control disease progression. Pre-clinical models suggest that exercise represents a non-pharmacologic means to reduce immune exhaustion, but no studies to date have examined the relationship between an exercise intervention and biomarkers of immune exhaustion in multiple myeloma patients.

Patients And Methods: The current study includes 24 multiple myeloma patients who participated in a six-month physical activity intervention, consisting of supervised strength training (n = 12) and unsupervised home-based walking arms (n = 12).

Probing cell proliferation: Considerations for dye selection.

Broadly speaking, cell tracking dyes are fluorescent compounds that bind stably to components on or within the cells so the fate of the labeled cells can be followed. Their staining should be bright and homogeneous without affecting cell function. For purposes of monitoring cell proliferation, each time a cell divides the intensity of cell tracking dye should diminish equally between daughter cells.

Minimal Residual Disease Status in Multiple Myeloma 1 Year After Autologous Hematopoietic Cell Transplantation and Lenalidomide Maintenance Are Associated With Long-Term Overall Survival.

Purpose: Prognostic Immunophenotyping in Myeloma Response (PRIMeR) is an ancillary study of minimal residual disease (MRD) assessment for multiple myeloma by next-generation multiparameter flow cytometry (MFC). Patients were enrolled on a three-arm randomized control trial (Blood and Marrow Transplants Clinical Trials Network 0702 Stem Cell Transplant for Myeloma in Combination of Novel Agents [STaMINA]; ClinicalTrials.gov identifier: NCT01109004).

Using Artificial Intelligence to Interpret Clinical Flow Cytometry Datasets for Automated Disease Diagnosis and/or Monitoring.

Flow cytometry (FC) is routinely used for hematological disease diagnosis and monitoring. Advancement in this technology allows us to measure an increasing number of markers simultaneously, generating complex high-dimensional datasets. However, current analytic software and methods rely on experienced analysts to perform labor-intensive manual inspection and interpretation on a series of 2-dimensional plots via a complex, sequential gating process.

Monitoring Cell Proliferation by Dye Dilution: Considerations for Panel Design.

High dimensional studies that include proliferation dyes face two inherent challenges in panel design. First, the more rounds of cell division to be monitored based on dye dilution, the greater the starting intensity of the labeled parent cells must be in order to distinguish highly divided daughter cells from background autofluorescence. Second, the greater their starting intensity, the more difficult it becomes to avoid spillover of proliferation dye signal into adjacent spectral channels, with resulting limitations on the use of other fluorochromes and ability to resolve dim signals of interest.

Effects of skin and mild core cooling on cognitive function in cold air in men.

This study tested the effects of skin and core cooling on cognitive function in 0°C cold air. Ten males completed a randomized, repeated measures study consisting of four environmental conditions: (i) 30 min of exposure to 22°C thermoneutral air (TN), (ii) 15 min to 0°C cold air which cooled skin temperature to ~27°C (CS), (iii) 0°C cold air exposure causing mild core cooling of ∆-0.3°C from baseline (C-0.

Systemic infusion of TLR3-ligand and IFN-α in patients with breast cancer reprograms local tumor microenvironments for selective CTL influx.

Background: Presence of cytotoxic T lymphocytes (CTL) in the tumor microenvironment (TME) predicts the effectiveness of cancer immunotherapies. The ability of toll-like receptor 3 (TLR3) ligands, interferons (IFNs) and COX2 inhibitors to synergistically induce CTL-attracting chemokines (but not regulatory T cell (Treg)-attractants) in the TME, but not in healthy tissues, observed in our preclinical studies, suggested that their systemic application can reprogram local TMEs.

Methods: Six evaluable patients (33-69 years) with metastatic triple-negative breast cancer received six doses of systemic chemokine-modulating (CKM) regimen composed of TLR3 ligand (rintatolimod; 200 mg; intravenous), IFN-α2b (20 MU/m; intravenous) and COX2 inhibitor (celecoxib; 2×200 mg; oral) over 2 weeks.

Endurance capacity impairment in cold air ranging from skin cooling to mild hypothermia.

We tested the effects of cold air (0°C) exposure on endurance capacity to different levels of cold strain ranging from skin cooling to core cooling of Δ-1.0°C. Ten males completed a randomized, crossover, control study consisting of a cycling time to exhaustion (TTE) at 70% of their peak power output following: ) 30-min of exposure to 22°C thermoneutral air (TN), ) 30-min exposure to 0°C air leading to a cold shell (CS), ) 0°C air exposure causing mild hypothermia of -0.

Synthesis of High Sn Content GeSiSn (0.1 < < 0.22) Semiconductors on Si for MWIR Direct Band Gap Applications.

A systematic effort has been described to grow ternary GeSiSn semiconductors on silicon with high Sn concentrations spanning the 9.5-21.2% range.

Tumor and immune remodeling following radiotherapy in human renal cell carcinoma.

Background: Studies evaluating peripheral patient samples show radiation can modulate immune responses, yet the biological changes in human tumors particularly at the cellular level remain largely unknown. Here, we address how radiation treatment shapes the immune compartment and interactions with cancer cells within renal cell carcinoma (RCC) patient tumors.

Methods: To identify how radiation shaped the immune compartment and potential immune interactions with tumor cells we evaluated RCC tumors from patients treated only with nephrectomy or with radiation followed by nephrectomy.

Short-Term Storage of Mobilized Peripheral Blood Stem Cells in a Closed System Changes the Microenvironment and May Affect the Quantity of CD34 and CD34CD38CD45RACD90 Cells.

Hypoxic conditions preserve the multipotency and self-renewing capacity of murine bone marrow and human cord blood stem cells. Blood samples stored in sealed blood gas tubes become hypoxic as leukocytes metabolize and consume oxygen. Taken together, these observations suggest that peripheral blood stem cell (PBSC) samples stored under airtight conditions become hypoxic, and that the stem cells contained may undergo qualitative or quantitative changes.

Considerations of Family Functioning and Clinical Interventions.

Levels of family functioning are an important consideration in determining appropriate clinical and educational intervention approaches for families and older adults. Theoretical and applied approaches are reviewed with the emphasis on specific interventions that support different levels of family functioning and caregiving. Additionally, different dynamics within the family and their relations with aging family members are examined.

Augmenting antibody response to EGF-depleting immunotherapy: Findings from a phase I trial of CIMAvax-EGF in combination with nivolumab in advanced stage NSCLC.

Background: CIMAvax-EGF is an epidermal growth factor (EGF)-depleting immunotherapy which has shown survival benefit as a switch maintenance treatment after platinum-based chemotherapy in advanced non-small cell lung cancer (NSCLC). The primary objective of this trial is to establish the safety and recommended phase II dose (RP2D) of CIMAvax-EGF in combination with nivolumab as second-line therapy for NSCLC.

Methods: Patients with immune checkpoint inhibitor-naive metastatic NSCLC were enrolled using a "3+3" dose-escalation design.

Spatiotemporal assessment of immunogenomic heterogeneity in multiple myeloma.

Spatial heterogeneity is a common phenomenon in metastatic solid tumors and an evolving concept in multiple myeloma (MM). The interplay between malignant plasma cells (PCs) and the microenvironment has not yet been analyzed in MM. For this purpose, we performed bone marrow aspirates and imaging-guided biopsies of corresponding lesions in newly diagnosed MM (NDMM) and relapsed/refractory MM (RRMM) patients.

Importance of external quality assessment for SARS-CoV-2 antigen detection during the COVID-19 pandemic.
