Self-Collection Blood Test for PFASs: Comparing Volumetric Microsamplers with a Traditional Serum Approach.

A remote sampling approach was developed at Eurofins for quantifying per- and polyfluoroalkyl substances (PFASs) in whole blood samples collected using volumetric absorptive microsamplers (VAMSs), which allow for self-collection of blood using a finger prick. This study compares PFAS exposure measured by self-collection of blood using VAMSs to the standard venous serum approach. Blood samples were collected from participants (n = 53) in a community with prior PFAS drinking water contamination using a venous blood draw as well as participant self-collection using VAMSs. Whole blood from the venous tubes was also loaded onto VAMSs to compare differences in capillary vs venous whole blood PFAS levels. Samples were quantified for PFASs using liquid chromatography tandem mass spectrometry and online solid-phase extraction. PFAS levels in serum were highly correlated with measurements in capillary VAMSs (r ≥ 0.91 and p < 0.05). Serum PFAS levels were generally twofold higher than whole blood, reflecting expected differences in their composition. Of interest, FOSA was detected in whole blood (both venous and capillary VAMSs) but not in serum. Overall, these findings indicate that VAMSs are useful self-collection tools for assessing elevated human exposure to PFASs.

Changes in Mental Health, Emotional Distress, and Substance Use Affecting Women Experiencing Violence and Their Service Providers during COVID-19 in a U.S. Southern State.

Research conducted during the COVID-19 pandemic has revealed many unintended consequences of mandated safety precautions, including increased perpetration of intimate partner violence (IPV), increases in substance use, and worsening mental health conditions. We conducted a repeated, cross-sectional survey of survivors of IPV, a longitudinal survey of service providers working in an IPV shelter, and interviews with both. We conducted surveys at the beginning of the pandemic and nearly half a year later to assess mental health and, for clients, substance use. Results showed that two small samples of survivors living in the shelter in 2020 and 2021 experienced both mental health decline and increased use of substances. Qualitative data from in-depth interviews suggest that COVID-19-related restrictions mirrored survivors' experiences of power and control in violent relationships. Further, IPV service providers-essential workers during COVID-19-experienced stress associated with reports of burnout and mental fatigue. This study suggests that community-based organizations can help mitigate the impacts of COVID-19 on survivors of IPV but should avoid adding additional work for staff as service providers experienced mental and emotional stress.

Shock wave formation from head-on collision of two subsonic vortex rings.

Vortex ring collisions have attracted intense interest in both water and air studies (Baird in Proc R Soc Lond Ser Math Phys Sci 409:59-65, 1987, Poudel et al. in Phys Fluids 33:096105, 2021, Lim and Nickels in Nature 357:225, 1992, New et al. in Exp Fluids 57:109, 2016, Suzuki et al. in Geophys Res Lett 34, 2007, Yan et al. in J Fluids Eng 140:054502, 2018, New et al. in J Fluid Mech 899, 2020, Cheng et al. in Phys Fluids 31:067107, 2019, Hernández and Reyes in 29:103604, 2017, Mishra et al. in Phys Rev Fluids, 2021, Zednikova et al. in Chem Eng Technol 42:843-850, 2019, Kwon et al. in Nature 600:64-69, 2021). These toroidal structures spin around a central axis and travel in the original direction of impulse while spinning around the core until inertial forces become predominant causing the vortex flow to spontaneously decay to turbulence (Vortex Rings, https://projects.iq.harvard.edu/smrlab/vortex-rings ). Previous studies have shown the collision of subsonic vortex rings resulting in reconnected vortex rings, but the production of a shock wave from the collision has not been demonstrated visibly (Lim and Nickels in Nature 357:225, 1992, Cheng et al. in Phys Fluids 31:067107, 2019). Here we present the formation of a shock wave due to the collision of explosively formed subsonic vortex rings. As the vortex rings travel at Mach 0.66 toward the collision point, they begin to trap high pressure air between them. Upon collision, high pressure air was imploded and released radially away from the axis of the collision, generating a visible shock wave traveling through and away from the colliding vortices at Mach 1.22. Our results demonstrate a pressure gradient with high pressure release creating a shock wave. We anticipate our study to be a starting point for more explosively formed vortex collisions. For example, explosives with different velocities of detonation could be tested to produce vortex rings of varying velocities.

"A reinstilled hope that they can change": Facilitator perspectives on a self-care and health promotion peer group program for veterans.

Introduction: This study assessed the relevance, value, and effectiveness of "Taking Charge of My Life and Health" (TCMLH), a patient wellbeing peer group program for U.S. veterans focused on empowering them to identify what really matters in their lives and to work toward health goals that align with their mission, aspirations, or purpose in life. The potential of TCMLH to empower veterans to engage in self-care behaviors, make health behavior changes, and participate in health care decision making is important, as veterans are more likely than the general population to suffer from multiple chronic conditions that require ongoing self-management. Methods: We conducted individual semi-structured interviews with 19 TCMLH facilitators serving in eight U.S. Veteran's Health Administration medical centers. Data were analyzed using an inductive approach to identify salient themes in facilitators' experiences. Results: Facilitators reported that TCMLH participants demonstrated positive attitude changes (e.g., greater confidence and hope) and behavior changes (e.g., making healthcare appointments and implementing self-care practices) by program completion. Further, findings show that mindful awareness practices, the peer group setting, Whole Health assessment tools, and goal setting tools were perceived as the most impactful program elements leading to positive health behavior change. Conclusion: Overall, findings suggest that this non-clinical peer group program can enhance patient wellbeing, and that there are certain program elements of TCMLH that are driving key attitudinal and behavioral changes.

Achieving Whole Health: A Preliminary Study of TCMLH, a Group-Based Program Promoting Self-Care and Empowerment Among Veterans.

OBJECTIVE: An emerging literature suggests patients with chronic illnesses can benefit from integrated, person-centric approaches to health care, including group-based programs. However, much of the research in this area is disease specific. The objective of this study was to collect preliminary evidence on the efficacy of Taking Charge of My Life and Health (TCMLH), a Whole Health group-based program that emphasizes self-care and empowerment on the overall health and well-being of veterans, a population burdened with high rates of multiple chronic conditions. METHOD: Self-reported outcomes, including standardized survey measures, were collected at pretest, posttest, and 2-month follow-up from 77 participants across 15 groups at four VA sites. Random intercept mixed-model regressions were used to analyze data. RESULTS: Results from this initial study showed high satisfaction with the program and facilitators, and high attendance. There were significant pre-post gains in self-care attitudes and behaviors, patient motivation, meaning and purpose, mental health, perceived stress, goal progress, and goal-specific hope. Outcomes were maintained at 2-month follow-up for patient motivation, perceived stress, goal-specific hope, and goal progress. Significant gains were observed in health care empowerment and physical health from pretest to follow-up. CONCLUSIONS: Preliminary findings support the efficacy of TCMLH, a Whole Health group-based program that emphasizes patient empowerment, self-care practices, and peer support. Future research priorities include a rigorous evaluation with a larger sample size and control group to assess effectiveness.

When Theater Comes to Engineering Design: Oh How Creative They Can Be.

The creative process is fun, complex, and sometimes frustrating, but it is critical to the future of our nation and progress in science, technology, engineering, mathematics (STEM), as well as other fields. Thus, we set out to see if implementing methods of active learning typical to the theater department could impact the creativity of senior capstone design students in the bioengineering (BE) department. Senior bioengineering capstone design students were allowed to self-select into groups. Prior to the beginning of coursework, all students completed a validated survey measuring engineering design self-efficacy. The control and experimental groups both received standard instruction, but in addition the experimental group received 1 h per week of creativity training developed by a theater professor. Following the semester, the students again completed the self-efficacy survey. The surveys were examined to identify differences in the initial and final self-efficacy in the experimental and control groups over the course of the semester. An analysis of variance was used to compare the experimental and control groups with p < 0.05 considered significant. Students in the experimental group reported more than a twofold (4.8 (C) versus 10.9 (E)) increase of confidence. Additionally, students in the experimental group were more motivated and less anxious when engaging in engineering design following the semester of creativity instruction. The results of this pilot study indicate that there is a significant potential to improve engineering students' creative self-efficacy through the implementation of a "curriculum of creativity" which is developed using theater methods.

Furosemide as a potential unintended urine drug screen confounder during methadone maintenance treatment.

Patients receiving chronic methadone maintenance treatment (MMT) for addiction are closely monitored for signs of relapse. Urine drug screen (UDS) comprises a major component of ongoing patient assessment. As patients continue with MMT, developing medical conditions may necessitate addition of medications that interfere with UDS. Although widely accepted as masking agents, little guidance is available regarding management of patients receiving MMT with legitimate medical need for diuretics. The following describes a case in which furosemide clinically interfered with UDS interpretation for a patient receiving MMT. Potential management strategies are also discussed.

High-yield expression in E. coli and refolding of the bZIP domain of activating transcription factor 5.

Activating transcription factor 5 (ATF5) recently has been demonstrated to play a critical role in promoting the survival of human glioblastoma cells. Interference with the function of ATF5 in an in vivo rat model caused glioma cell death in primary tumors but did not affect the status of normal cells surrounding the tumor, suggesting ATF5 may prove an ideal target for anti-cancer therapy. In order to examine ATF5 as a pharmaceutical target, the protein must be produced and purified to sufficient quantity to begin analyses. Here, a procedure for expressing and refolding the bZIP domain of ATF5 in sufficient yield and final concentration to permit assay development and structural characterization of this target using solution NMR is reported. Two-dimensional NMR and circular dichroism analyses indicate the protein exists in the partially alpha-helical, monomeric x-form conformation with only a small fraction of ATF5 participating in formation of higher-order structure, presumably coiled-coil homodimerization. Despite the persistence of monomers in solution even at high concentration, an electrophoretic mobility shift assay showed that ATF5 is able to bind to the cAMP response element (CRE) DNA motif. Polyacrylamide gel electrophoresis and mass spectrometry were used to confirm that ATF5 can participate in homodimer formation and that this dimerization is mediated by disulfide bond formation.
