BACKGROUND:Persistent immune activation is linked to elevated cardiovascular diseases in people with HIV on antiretroviral therapy. The fat attenuation index (FAI) is a measure of peri-coronary inflammation that independently predicts cardiovascular disease risk in people without HIV. Whether FAI is associated with immune activation is unknown. METHODS:Peripheral blood T-cell activation and homing phenotypes were measured in people with HIV (n=58) and people without HIV (n=16) without known cardiovascular disease who underwent coronary computed tomography angiography and had FAI measurements. A cross-sectional analysis of an observational cohort was performed. The primary aim was to evaluate associations of T-cell activation and phenotypes with the outcome variables, FAI values of the right coronary artery and left anterior descending artery, which were assessed using multivariable regression models adjusted for age, natal sex, race, low-density lipoprotein cholesterol, body mass index, and use of lipid-lowering medication. RESULTS:T cells from people with HIV showed greater activation, as measured by cluster of differentiation (CD) 38/human leukocyte antigen - DR isotype coexpression on CD4 central memory and terminally-differentiated effector memory subsets and on CD8 effector memory (TEM), than did cells from people without HIV. Expression of the chemokine receptor C-C Chemokine Receptor 2 was reduced on CD4 central memory and TEM and CD8 TEM and terminally-differentiated effector memory subsets in people with HIV. Among all participants, PD-1 (programmed cell death 1) in CD8 central memory was associated with worsened peri-coronary inflammation of the right coronary artery, whereas perforin/granzyme B on CD8 TEM was associated with improved peri-coronary inflammation of the right coronary artery and left anterior descending artery in adjusted analyses. When accounting for HIV serostatus, CD38/human leukocyte antigen - DR isotype coexpression on CD8 central memory, TEM, and terminally-differentiated effector memory cells was associated with more peri-coronary inflammation of the left anterior descending artery. CONCLUSIONS:The associations between T-cell activation with FAI are novel and suggest that T-cell activation may be an important driver of peri-coronary inflammation, occurring at an early stage of atherosclerosis, even before the development of clinical disease.

Background: Community Acquired Pneumonia (CAP) is the most common reason for antibiotic treatment in hospitalized adults. Some prior studies have found treatment differences by race/ethnicity but research on the topic is limited, results are mixed, and it is unclear if clinical outcomes are affected. We sought to examine whether guideline-concordant CAP care and patient outcomes varied by race/ethnicity. Methods: Using the Vizient clinical database, we conducted a cross sectional analysis of all hospitalized patients > = 18 years of age with a primary diagnosis of pneumonia (ICD10 codes: J12-J18) from 2018-2021. Univariate and bivariate analyses examined the distribution of demographic, clinical and hospital characteristics across race/ethnicity. The primary outcome was receipt of therapy concordant with ATS/IDSA Clinical Practice Guideline for CAP. Final models included only patients with bacterial pneumonia and examined the relationship between race/ethnicity and guideline-concordant antibiotic treatment. Secondary analysis examined the interaction between race/ethnicity and concordant antibiotic treatment with length of stay >7 days, 30-day hospital readmission, adverse events or complications in separate models. We used hierarchical multivariable regression models accounting for clustering within patients and among patients hospitalized at the same facility. Due to sample size, significance was assessed with an OR > = 1.2 and p≤ 0.05. All analyses used SAS (v.9.4, SAS Institute Inc. Cary, NC). Results: There were 1,277,770 admissions with a primary diagnosis of bacterial CAP. Sixty-nine percent of the sample was White, 18% Black, 8% Hispanic, 2% Asian and 3% identified as other. 56% of the sample received concordant care. In adjusted models Black patients had greater odds of overall concordant care (OR 1.22; p 7 days (OR 0.67 p <.0001), complication or adverse event (OR 0.75 p <.0001), but not readmission within 30 days. Conclusion: We observed differences between Black and White patients in the receipt of concordant treatment. Hospital bed size, CMI and region played an important role in both antibiotic treatment decisions and clinical outcomes, indicating that hospital and regional prescribing cultures may play in role in treatment inequities.

Background: Acute chest syndrome (ACS), the second most common cause of hospitalization and leading cause of death in children with sickle cell disease (SCD), often develops during a hospitalization for acute SCD in the setting of chest wall splinting, hypoventilation, and atelectasis from pain and opioid use. While incentive spirometry is an important component of ACS prevention and management, additional strategies are needed to prevent atelectasis during sleep. Bi-level positive airway pressure ventilation (BiPAP) provides positive pressure breaths through a mask to support ventilation, and is most commonly used to treat respiratory failure and chronic obstructive sleep apnea,. In 2021, we published our clinical innovation using BiPAP during sleep as supportive care during 53 hospitalizations on the general pediatric inpatient unit for hospitalized children with SCD to prevent ACS and/or to prevent acute respiratory failure among children with mild-moderate ACS. We found that our novel use of BiPAP was safe and feasible on a general pediatric unit; when recommended, it was tolerated in 40/53 (75%) hospitalizations. The goal of the current qualitative study was to identify perceived benefits and harms, and facilitators and barriers to the use and widespread implementation of “supportive non-invasive ventilation for ACS prevention” (SNAP) on a general pediatric inpatient unit. Methods: We conducted semi-structured interviews with key implementation partners at Boston Medical Center (pediatric hospitalists and hematologists; nurses, respiratory therapists, child life specialists, clinical leadership, patients, and parents) about their experiences with and perceptions of SNAP. Interviews and a priori codes for the preliminary codebook were guided by the Promoting Action Research on Implementation in Health Services (PARiHS) framework using the Evidence, Context, and Facilitation constructs. Interviews were transcribed, checked for accuracy, and imported into NVivo 12 for analysis. Transcripts were double coded by three team members who independently coded the initial transcripts. The codebook was refined until consensus was reached. Team members independently reviewed data to identify preliminary themes and subsequently consolidated themes as a group. We were particularly interested in themes regarding benefits, advantages, disadvantages, facilitators, and barriers to individual use and institutional implementation of BiPAP as supportive care. Results: Interviews were completed with 16 participants until thematic saturation was reached, including: 5 physicians, 4 nurses, 1 respiratory therapist, 1 child life specialist, 3 parents, and 2 patients. One physician and one nurse had administrative leadership roles. Major themes included: 1) Participants believed that BiPAP is effective at preventing ACS and - when already present - effective at preventing ACS from getting worse. 2) Despite some initial hesitation, inpatient team members endorsed that use of BiPAP on the general pediatric inpatient unit is appropriate. 3) Improving the patient experience with BiPAP is essential and requires a multi-tiered approach including both physical and social components. 4) Communication among inpatient team members and between staff and patients was critical for BiPAP initiation and success. 5) Nurses were key to the intervention success and required additional support. 6) The size of clinical unit and a “buy-in” culture supported intervention success . See Table 1 for detailed subthemes. Conclusions/Future directions: Members of the health care team, patients, and parents perceive SNAP as effective at preventing ACS and respiratory decompensation, and believe that it is appropriate for use with stable hospitalized children at risk for ACS on a general pediatrics inpatient unit. Features of our inpatient pediatrics unit (small size and collaborative relationships between physicians, staff, and nursing leadership) facilitated successful implementation. Improving the patient experience remains a challenge, and will involve technical issues (mask comfort and pressure) and enhanced communication among health care team members and between staff, patients, and caregivers. We are utilizing these data to develop a protocol for a multicenter hybrid effectiveness/implementation trial of SNAP that incorporates these strategies.

Long-acting injectable (LAI) antiretroviral therapy (ART) has the potential to change the lives of people living with HIV (PLWH). To ensure equitable access to new treatment modalities, we examined the feasibility and acceptability of administering Cabotegravir Rilpivirine Long Acting (CAB/RPV LA) to individuals who experience challenging social determinants of health (SDoH) and struggle with adherence to traditional oral ART. Quantitative and qualitative data were used to assess feasibility of utilizing ART at alternative clinic. Data were collected on individuals eligible to receive CAB/RPV LA at an alternative street-based clinic and on individuals receiving CAB/RPV LA at a traditional HIV clinic. After 6 months, participants were interviewed about their experience. Providers involved in the implementation were also interviewed about their experiences. Only one participant (out of 5) who received CAB/RPV LA at the alternative clinic received consistent treatment, whereas 17 out of 18 participants receiving CAB/RPV LA at the traditional clinic site were adherent. Participants and providers believed that LAI had potential for making treatment adherence easier, but identified several barriers, including discrepancies between patients' desires and their lifestyles, impact of LAI on interactions with the medical system, risk of resistance accompanying sub-optimal adherence, and need for a very high level of resources. While LAI has major potential benefits for high-risk patients, these benefits must be balanced with the complexities of implementation. Despite challenges that impacted study outcomes, improving treatment outcomes for PLWH requires addressing SDoH and substance use.

Introduction: People with HIV (PWH) have an increased risk of atherosclerotic cardiovascular disease (ASCVD) compared to non-PWH, but the reasons for this increased risk remain elusive. We investigated the change in ASCVD risk scores over 4 years to identify clinical factors associated with change in risk scores or high-risk scores. Methods: We conducted a preliminary study using retrospective analysis of PWH, between 40 and 75 years old, seen at the Evelyn Jordan Center with at least two routine HIV visits. We collected clinical and demographic data and calculated the ASCVD risk scores using the Pooled Cohort Equation. Exploratory analyses examined change in risk score categories over time. Final adjusted analysis examined factors associated with change in continuous risk scores over time. Results: Our sample included 187 PWH; 166 were black/African American and 79 were female. We found no significant change in ASCVD risk score over time. The risk score was significantly higher in PWH with hepatitis C (7.34%; 95% CI: 2.59, 12.09; p = 0.003) and trended higher in those with dual hepatitis B/C and hepatitis B compared to those without hepatitis (p = 0.07). Conclusion: We found that ASCVD risk did not change over a 4-year period among predominantly black young PWH, but infection with hepatitis C and dual hepatitis B/C were associated with higher ASCVD risk scores. Our findings illustrate the need for further longitudinal studies evaluating change in cardiovascular disease (CVD) risk and investigating viral hepatitis as an added potential contributor to increased CVD risk in high-risk, vulnerable populations.

BACKGROUNDPersons with HIV (PWH) have an increased risk of developing cardiovascular disease (CVD) compared to persons without HIV (PWoH). Lipoprotein a (Lp(a)) is a known atherosclerotic risk factor in PWoH, but there are no studies investigating Lp(a) and peri-coronary inflammation.OBJECTIVETo investigate whether Lp(a) is associated with peri-coronary inflammation as assessed by the fat attenuation index (FAI) and activated monocytes and T lymphocytes in PWH and PWoH.METHODSWe measured plasma levels of Lp(a) at study entry in 58 PWH and 21 PWoH without CVD and who had FAI measurements. Associations of Lp(a) with FAI values of the right coronary artery (RCA) and left anterior descending artery (LAD) were evaluated using multivariable regression models adjusted for potential confounders. Correlations between Lp(a) levels and systemic inflammatory markers and immune cell subsets were examined.RESULTSLp(a) was associated with greater peri-coronary inflammation among PWH compared to PWoH (β=1.73, P=0.019) in the RCA, in adjusted models. Significant correlations were observed with certain inflammatory markers (TNFR-I, b=0.295, P<0.001; TNFR-II, b=0.270, P=0.002; hs-CRP, b=0.195, P=0.028). Significant correlations were found between Lp(a) levels and several markers of monocyte activation: CD16 -CD163+ (b= -0.199, P=0.024), and CD16 -DR+ MFI (b= -0.179, P=0.042) and T cell subset CD38+CD4+ TEMRA (b= 0.177, P= 0.044).CONCLUSIONSLp(a) was associated with greater peri-coronary inflammation in the RCA in PWH compared to PWoH, as well as with select systemic inflammatory markers and specific subsets of immune cells in peripheral circulation.

RATIONALE:Acute chest syndrome (ACS) often develops during hospitalizations for sickle cell disease (SCD) vaso-occlusive episodes and may be triggered by a combination of chest wall splinting, opioid use, hypoventilation, and atelectasis. In 2017, Boston Medical Center's general pediatric inpatient unit instituted the novel use of bi-level positive airway pressure (BiPAP) as "supportive non-invasive ventilation for ACS prevention" (SNAP) to prevent ACS and respiratory decompensation. OBJECTIVE:The goals of this qualitative study were to identify perceived benefits, harms, facilitators, and barriers to use of SNAP. METHODS:We conducted semi-structured key informant interviews at three sites with different levels of SNAP implementation (Site 1: extensive implementation; Site 2: limited implementation; Site 3: not yet implemented) regarding experiences with and/or perceptions of SNAP. Interviews and coding were guided by the Promoting Action on Research Implementation in Health Services (PARiHS) framework. RESULTS:Thirty-four participants (physicians, nurses, respiratory therapists, child life specialists, psychologists, youth with SCD, and parents) completed interviews. Major themes included: (i) participants perceive BiPAP as effective at preventing ACS, and for those with medically stable ACS, for preventing respiratory decompensation. (ii) BiPAP use is appropriate on the general pediatric inpatient unit for medically stable patients with SCD. (iii) Improving the patient experience is the most important factor to optimize acceptance of BiPAP by patients and families. CONCLUSION/FUTURE DIRECTIONS:SNAP is perceived as effective and appropriate for hospitalized pediatric patients with SCD. Improving the patient experience is the biggest challenge. These data will inform a future protocol for a multicenter hybrid effectiveness/implementation trial of SNAP.

Introduction Adherence to daily oral antiretroviral therapy (ART) and regular clinic appointments can be challenging for individuals who experience adverse social determinants of health. Long-acting injectable ART administered outside of traditional clinic settings may be a promising solution to adherence barriers, but additional research is needed to assess patients’ perspectives. This study assessed perspectives of people living with HIV (PLWH) who had difficulty with adherence to traditional HIV care models and evaluated feasibility and acceptability of receiving a long-acting ART injection at a location outside of a traditional HIV clinic to address barriers to HIV care. Methods Qualitative interviews ( n = 26) were conducted with PLWH who had experienced barriers to adherence. Participants were referred to the study by staff from Project Trust, a drop in harm reduction and sexually transmitted infection/HIV clinic. The interviews were conducted between May and November 2021. Interviews were recorded, professionally transcribed, coded, and analyzed qualitatively using the integrated-Promoting Action on Research Implementation in Health Services framework. Results We identified 6 main themes regarding the acceptability of receiving a long-acting injection to treat HIV, and the acceptability and feasibility of receiving injections at an alternative care site. Participants specified that they: (1) have a general understanding about their HIV care and the importance of ART adherence, (2) prefer a long-acting injection over a daily pill regimen, (3) expressed concerns about injection safety and efficacy, (4) had specific logistical aspects around the delivery of long-acting injections, including location of injection administration, that they believed would improve their ability to adhere, (5) have confidence that they can become undetectable and then complete the oral lead-in required to begin receiving the injection, and (6) see potential barriers that remain a concern for successful adherence to long-acting injections. Conclusion To better treat HIV among people who are living with challenging social determinants of health, interventions that include a long-acting injection in a non-traditional care setting may prove to be a promising treatment option.

Infection preventionist (IP) positions are difficult to fill, and future workforce shortages are anticipated. The IP field has less racial and ethnic diversity than the general nursing workforce or patient population. A targeted fellowship program for underrepresented groups allowed the recruitment and training of IPs while avoiding staffing shortages.

To explore the mental health impacts of the COVID-19 pandemic on healthcare workers in Massachusetts and identify potential strategies to maintain the healthcare workforce we conducted a sequential exploratory mixed methods study. Fifty-two individuals completed interviews from April 22nd - September 7th, 2021; 209 individuals completed an online survey from February 17th - March 23rd, 2022. Interviews and surveys asked about the mental health impacts of working in healthcare during the COVID-19 pandemic, burnout, longevity in the workplace, and strategies for reducing attrition. Interview and survey participants were predominantly White (56%; 73%, respectively), female (79%; 81%) and worked as physicians (37%; 34%). Interviewees indicated high stress and anxiety levels due to frequent exposure to patient deaths from COVID-19. Among survey respondents, 55% reported worse mental health than before the pandemic, 29% reported a new/worsening mental health condition for themselves or their family, 59% reported feeling burned out at least weekly, and 37% intended to leave healthcare in less than 5 years. To decrease attrition, respondents suggested higher salaries (91%), flexible schedules (90%), and increased support to care for patients (89%). Healthcare workers’ experiences with death, feeling unvalued, and overworked resulted in unprecedented rates of burnout and intention to leave healthcare.

OBJECTIVE To examine the perspectives of caregivers that are not part of the antibiotic stewardship program (ASP) leadership team (eg, physicians, nurses, and clinical pharmacists), but who interact with ASPs in their role as frontline healthcare workers. DESIGN Qualitative semistructured interviews. SETTING The study was conducted in 2 large national healthcare systems including 7 hospitals in the Veterans' Health Administration and 4 hospitals in Intermountain Healthcare. PARTICIPANTS We interviewed 157 participants. The current analysis includes 123 nonsteward clinicians: 47 physicians, 26 pharmacists, 29 nurses, and 21 hospital leaders. METHODS Interviewers utilized a semistructured interview guide based on the Consolidated Framework for Implementation Research (CFIR), which was tailored to the participant's role in the hospital as it related to ASPs. Qualitative analysis was conducted using a codebook based on the CFIR. RESULTS We identified 4 primary perspectives regarding ASPs. (1) Non-ASP pharmacists considered antibiotic stewardship activities to be a high priority despite the added burden to work duties: (2) Nurses acknowledged limited understanding of ASP activities or involvement with these programs; (3) Physicians criticized ASPs for their restrictions on clinical autonomy and questioned the ability of antibiotic stewards to make recommendations without the full clinical picture; And (4) hospital leaders expressed support for ASPs and recognized the unique challenges faced by non-ASP clinical staff. CONCLUSION Further understanding these differing perspectives of ASP implementation will inform possible ways to improve ASP implementation across clinical roles.

Background. Inflammation is linked to elevated cardiovascular disease (CVD) risk in people with HIV (PWH) on antiretroviral therapy (ART). Fat attenuation index (FAI) is a measure of peri-coronary inflammation that independently predicts CVD risk in HIV-uninfected persons. Whether FAI is associated with soluble inflammatory markers is unknown. Methods. Plasma levels of inflammatory markers were measured in 58 PWH and 16 controls without current symptoms or prior known CVD who underwent coronary computed tomography angiography and had FAI measurements. A cross-sectional analysis was performed, and associations of markers with FAI values of the right coronary artery (RCA) and left anterior descending artery (LAD) were assessed using multivariable regression models adjusted for the potential confounders age, sex, race, low-density lipoprotein cholesterol, body mass index, and use of lipid-lowering medication. Results. Several inflammatory markers had significant associations with RCA or LAD FAI in adjusted models, including sCD14, sCD163, TNFR-I, and TNFR-II, CCL5, CX3CL1, IP-10. Conclusions. The associations between indices of systemic and peri-coronary inflammation are novel and suggest that these systemic markers and FAI together are promising noninvasive biomarkers that can be applied to assess asymptomatic CVD in people with and without HIV; they also may be useful tools to evaluate effects of anti-inflammatory interventions.

Mindfulness-based interventions (MBIs) have emerged as promising prophylactic episodic migraine treatments. The present study investigated biopsychosocial predictors and outcomes associated with formal, daily-life meditation practice in migraine patients undergoing MBI, and whether augmented mindfulness mechanistically underlies change. Secondary analyses of clinical trial data comparing a 12-week enhanced mindfulness-based stress reduction course (MBSR + ; n = 50) to stress management for headache (SMH; n = 48) were conducted. Pre-treatment mesocorticolimbic system functioning (i.e., greater resting state ventromedial prefrontal cortex-right nucleus accumbens [vmPFC-rNAC] functional connectivity) predicted greater meditation practice duration over MBSR + (r = 0.58, p = 0.001), as well as the change in headache frequency from pre- to post-treatment (B = − 12.60, p = 0.02) such that MBSR + participants with greater vmPFC-rNAC connectivity showed greater reductions in headache frequency. MBSR + participants who meditated more showed greater increases in mindfulness (B = 0.52, p = 0.02) and reductions in the helplessness facet of pain catastrophizing (B = − 0.13, p = 0.01), but not headache frequency, severity, or impact. Augmented mindfulness mediated reductions in headache impact resulting from MBSR + , but not headache frequency. Mesocorticolimbic system function is implicated in motivated behavior, and thus, motivation-enhancing interventions might be delivered alongside mindfulness-based training to enhance meditation practice engagement. Formal, daily-life meditation practice duration appears to benefit pain-related cognitions, but not clinical pain, while mindfulness emerges as a mechanism of MBIs on headache impact, but not frequency. Further research is needed to investigate the day-to-day effects of formal, daily-life meditation practice on pain, and continue to characterize the specific mechanisms of MBIs on headache outcomes. This study is not preregistered.

Aim:To examine experiences and attitudes of a diverse sample of clinical and non-clinical healthcare workers regarding COVID-19 vaccines and boosters for themselves, their patients, and their communities.Subject and methods:We conducted a sequential exploratory mixed methods study; 52 healthcare workers participated in qualitative interviews between April 22 and September 7, 2021, and 209 healthcare workers completed surveys between February 17 and March 23, 2022. Interviews and survey questions asked about personal attitudes toward COVID-19 vaccination and boosters and experiences discussing vaccination with patients.Results:Participants were predominantly White (56% and 73%, respectively) and female (79% and 81%, respectively). Factors motivating healthcare workers to take the vaccine were the belief that vaccination would protect themselves, their families, patients, and communities. Healthcare workers were accepting of and had high receipt of the booster, though some had diminished belief in its effectiveness after becoming infected with SARS-CoV-2 after initial vaccination. Race related mistrust, misinformation related to vaccine safety, and concerns about vaccine effects during pregnancy were the most common barriers that providers encountered among their patients and communities.Conclusions:Healthcare workers' primary motivation to receive COVID-19 vaccines was the desire to protect themselves and others. Healthcare workers' perception was that concerns about safety and misinformation were more important barriers for their patients than themselves. Race-related medical mistrust amplified concerns about vaccine safety and hindered communication efforts.

Abstract Patients with migraine suffer from high morbidity related to the repeated headache attacks, characteristic of the disorder, poor sleep, and a high prevalence of comorbid psychosocial disorders. Current pharmacological therapies do not address these aspects of migraine, but nonpharmacological treatments such as mindfulness-based stress reduction (MBSR) have been shown to improve both pain and psychological well-being. In this secondary analysis, we examined the change over time in sleep quality and psychosocial outcomes from the magnetic resonance imaging outcomes for mindfulness meditation clinical trial and assessed how these mediated treatment response (50% reduction in headache frequency postintervention). We also examined the relationship between baseline values and treatment response. The trial (primary outcomes previously reported) included 98 patients with episodic migraine randomized to either enhanced MBSR (MBSR+) or stress management for headache. They completed psychosocial questionnaires and headache diaries at baseline (preintervention), midintervention (10 weeks after baseline), and postintervention (20 weeks after baseline). There was a significant improvement in sleep quality from baseline to postintervention (P = 0.0025) in both groups. There were no significant changes from baseline or between groups in anxiety, depression, and stress. There was also no significant association between baseline scores and treatment response. Mediation analysis showed a significant indirect effect of 6% for sleep: In other words, small improvements in sleep may have contributed to the efficacy of MBSR+. Trial registration: NCT02133209.

Objective: People with HIV (PWH) and co-infected with hepatitis C virus (PWH + HCV) have increased risk of cardiovascular disease (CVD). Peri-coronary inflammation, measured by fat attenuation index (FAI) on coronary computed tomography angiography (CCTA), independently predicts cardiovascular risk in the general population but has not been studied in the PWH + HCV population. We tested whether peri-coronary inflammation is increased in PWH or PWH + HCV, and whether inflammation changes over time. Design: Cross-sectional analysis to determine FAI differences among groups. Longitudinal analysis in PWH to assess changes in inflammation over time. Methods: Age-matched and sex-matched seropositive groups (PWH and PWH + HCV) virologically suppressed on antiretroviral therapy, HCV viremic, and without prior CVD and matched controls underwent CCTA. Peri-coronary FAI was measured around the proximal right coronary artery (RCA) and left anterior descending artery (LAD). Follow-up CCTA was performed in 22 PWH after 20.6–27.4 months. Results: A total of 101 participants (48 women) were studied (60 PWH, 19 PWH + HCV and 22 controls). In adjusted analyses, peri-coronary FAI did not differ between seropositive groups and controls. Low attenuation coronary plaque was significantly less common in seropositive groups compared with controls (LAD, P = 0.035; and RCA, P = 0.017, respectively). Peri-coronary FAI values significantly progressed between baseline and follow-up in PWH (RCA: P = 0.001, LAD: P = <0.001). Conclusion: PWH and PWH + HCV without history of CVD do not have significantly worse peri-coronary inflammation, assessed by FAI, compared with matched controls. However, peri-coronary inflammation in mono-infected PWH significantly increased over approximately 22 months. FAI measures may be an important imaging biomarker for tracking asymptomatic CVD progression in PWH.

Healthcare workers are a trusted health information source and are uniquely positioned to reduce the burden of the COVID-19 pandemic. The purpose of this sequential exploratory mixed methods study was to understand attitudes of healthcare workers working in Massachusetts during the COVID-19 pandemic regarding strategies to improve COVID-19 vaccine utilization, including vaccine mandates and incentives. Fifty-two individuals completed one-on-one interviews between April 22(nd) and September 7th, 2021. The survey was developed based on findings from the interviews; 209 individuals completed the online survey between February 17(th) and March 23(rd), 2022. Both the interview and survey asked about attitudes toward COVID-19 vaccine and booster mandates, incentives, and strategies to improve vaccination rates. Most participants were female (79%-interview, 81%-survey), Caucasian (56%, 73%), and worked as physicians (37%, 34%) or nurses (10%, 18%). Overall, nuanced attitudes regarding vaccine and booster mandates were expressed; many supported mandates to protect their patients' health, others emphasized personal autonomy, while some were against mandates if job termination was the consequence of declining vaccines. Similarly, views regarding vaccine incentives differed; some considered incentives helpful, yet many viewed them as coercive. Strategies believed to be most effective to encourage vaccination included improving accessibility to vaccination sites, addressing misinformation, discussing vaccine safety, tailored community outreach via trusted messengers, and one-on-one conversations between patients and healthcare workers. Healthcare workers' experiences with strategies to improve utilization of COVID-19 vaccines and boosters have implications for public health policies. Generally, efforts to improve access and education were viewed more favorably than incentives and mandates.

Formal training in mindfulness-based practices promotes reduced experimental and clini-cal pain, which may be driven by reduced emotional pain reactivity and undergirded by alterations in the default mode network, implicated in mind-wandering and self-referential processing. Recent results published in this journal suggest that mindfulness, defined here as the day-to-day tendency to maintain a non-reactive mental state in the absence of training, associates with lower pain reactiv-ity, greater heat-pain thresholds, and resting-state default mode network functional connectivity in healthy adults in a similar manner to trained mindfulness. The extent to which these findings extend to chronic pain samples and replicate in healthy samples is unknown. Using data from healthy adults (n = 36) and episodic migraine patients (n = 98) and replicating previously published methods, we observed no significant association between mindfulness and heat-pain threshold, pain intensity or unpleasantness, or pain catastrophizing in healthy controls, or between mindfulness and headache frequency, severity, impactor pain catastrophizing in patients. There was no association between default mode network connectivity and mindfulness in either sample when probed via seed-based functional connectivity analyses. In post-hoc whole brain exploratory analyses, a meta-analytically derived default mode network node (ie, posterior cingulate cortex) showed connectivity with regions unassociated with pain processing as a function of mindfulness, such that healthy adults higher in mindfulness showed greater functional connectivity between the posterior cingulate cortex-and cere-bellum. Collectively, these findings suggest that the relationship between mindfulness and default mode network functional connectivity may be nuanced or non-robust, and encourage further investi-gation of how mindfulness relates to pain. Perspective: This study found few significant associations between dispositional mindfulness and pain, pain reactivity and default mode connectivity in healthy adults and migraine patients. The rela-tionship between mindfulness and default mode network connectivity may be nuanced or non-robust.

Background Respiratory tract infections (RTIs) are often inappropriately treated with antibiotics. Rapid diagnostic tests (RDTs) have been developed with the aim of improving antibiotic prescribing but uptake remains low. The aim of this study was to examine provider knowledge, attitudes and behaviors regarding RDT use and their relationship to antibiotic prescribing decisions across multiple clinical departments in an urban safety-net hospital. Methods We conducted a mixed methods sequential explanatory study. Providers with prescribing authority (attending physicians, nurse practitioners and physician assistants) who had at least 20 RTI encounters from January 1, 2016 to December 31, 2018. Eighty-five providers completed surveys and 16 participated in interviews. We conducted electronic surveys via RedCap from April to July 2019, followed by semi-structured individual interviews from October to December 2019, to ascertain knowledge, attitudes and behaviors related to RDT use and antibiotic prescribing. Results Survey findings indicated that providers felt knowledgeable about antibiotic prescribing guidelines. They reported high familiarity with the rapid streptococcus and rapid influenza tests. Familiarity with comprehensive respiratory panel PCR (RPP-respiratory panel PCR) and procalcitonin differed by clinical department. Qualitative interviews identified four main themes: providers trust their clinical judgment more than rapid test results; patient-provider relationships play an important role in prescribing decisions; there is patient demand for antibiotics and providers employ different strategies to address the demand and providers do not believe RDTs are implemented with sufficient education or evidence for clinical practice. Conclusion Prescribers are knowledgeable about prescribing guidelines but often rely on clinical judgement to make final decisions. The utility of RDTs is specific to the type of RDT and the clinical department. Given the low familiarity and clinical utility of RPP and procalcitonin, providers may require additional education and these tests may need to be implemented differently based on clinical department.
