Macrophage Migration Inhibitory Factor (MIF) Makes Complex Contributions to Pain-Related Hyperactivity of Nociceptors after Spinal Cord Injury.

Neuropathic pain is a major, inadequately treated challenge for people with spinal cord injury (SCI). While SCI pain mechanisms are often assumed to be in the central nervous system, rodent studies have revealed mechanistic contributions from primary nociceptors. These neurons become chronically hyperexcitable after SCI, generating ongoing electrical activity (OA) that promotes ongoing pain. A major question is whether extrinsic chemical signals help to drive OA after SCI. People living with SCI exhibit acute and chronic elevation of circulating levels of macrophage migration inhibitory factor (MIF), a cytokine implicated in preclinical pain models. Probable nociceptors isolated from male rats and exposed to a MIF concentration reported in human plasma (1 ng/ml) showed hyperactivity similar to that induced by SCI, although, surprisingly, a ten-fold higher concentration failed to increase excitability. Conditioned behavioral aversion to a chamber associated with peripheral MIF injection suggested that MIF stimulates affective pain. A MIF inhibitor, Iso-1, reversed SCI-induced hyperexcitability. Unlike after SCI, acute MIF-induced hyperexcitability was only partially abrogated by inhibiting ERK signaling. Unexpectedly, MIF concentrations that induced hyperactivity in nociceptors from Naïve animals, after SCI induced a long-lasting conversion from a highly excitable nonaccommodating type to a rapidly accommodating, hypoexcitable type, possibly as a homeostatic response to prolonged depolarization. Treatment with conditioned medium from cultures of dorsal root ganglion (DRG) cells obtained after SCI was sufficient to induce MIF-dependent hyperactivity in neurons from Naïve rats. Thus, changes in systemic and DRG levels of MIF may help to maintain SCI-induced nociceptor hyperactivity that persistently promotes pain.Significance Statement:Chronic neuropathic pain is a major challenge for people with spinal cord injury (SCI). Pain can drastically impair quality of life, and produces substantial economic and social burdens. Available treatments, including opioids, remain inadequate. This study shows that the cytokine macrophage migration inhibitory factor (MIF) can induce pain-like behavior and plays an important role in driving persistent ongoing electrical activity in injury-detecting sensory neurons (nociceptors) in a rat SCI model. The results indicate that SCI produces an increase in MIF release within sensory ganglia. Low MIF levels potently excite nociceptors, but higher levels trigger a long-lasting hypoexcitable state. These findings suggest that therapeutic targeting of MIF in neuropathic pain states may reduce pain and sensory dysfunction by curbing nociceptor hyperactivity.

A 4-week morning light treatment with stable sleep timing for individuals with fibromyalgia: a randomized controlled trial.

OBJECTIVES: Fibromyalgia is characterized by chronic widespread pain, mood, and sleep disturbance. Pharmacological treatments have modest efficacy and are associated with negative side effects, and alternative approaches are needed. Morning bright light treatment may assist in the management of fibromyalgia as it can reduce depressive symptoms, improve sleep, and advance circadian timing. METHODS: Sixty people with fibromyalgia (58 women, mean age 41.8 ± 13.3 years) were enrolled in a study comparing 4 weeks of a 1-hour daily morning bright light treatment (active treatment) to a morning dim light treatment (comparison treatment). Both light treatments included behavioral procedures to stabilize sleep timing. The morning bright light treatment was expected to produce larger improvements in pain and function than the dim light treatment and larger improvements in potential mediators (mood, sleep, and circadian timing). RESULTS: Both the bright and dim light treatment groups achieved significant but similar levels of improvement in pain intensity, pain interference, physical function, depressive symptoms, and sleep disturbance. Overall, the sample on average displayed a clinically meaningful improvement in the Fibromyalgia Impact Questionnaire-Revised score (mean reduction of 11.2 points), comparable to that reported following physical exercise treatments. Minimal side effects were observed. CONCLUSIONS: Findings indicate that the effects of a morning bright light treatment did not exceed those of a comparison dim light treatment; yet the changes on average in both conditions revealed clinically meaningful improvements. Future research is warranted to identify what elements of this trial may have contributed to the observed effects.

Contraception-related knowledge, attitude, belief contexts among US women experiencing homelessness: A scoping review.

Contraception provision may help reduce undesired pregnancies, but women experiencing homelessness may have low health literacy, specific attitudes, and certain beliefs that influence contraception uptake. This scoping review identifies what is known about pregnancy prevention and contraception knowledge, attitudes, and beliefs among US women experiencing homelessness. This review examined English articles that measured the context of knowledge, attitudes, and beliefs related to contraceptive use for avoiding pregnancy among US women experiencing homelessness. Using PRISMA-ScR guidelines, articles published before May 2022 were located via PubMed, EBSCOhost, and Embase. The initial search identified 1204 articles, and 10 met the inclusion criteria. There were five quantitative, four qualitative, and one mixed-methods study, published between 2000 and 2022, with samples of 15-764 women ranging from ages 15-51. Contraception knowledge, attitudes, and beliefs related to pregnancy prevention suggested several knowledge gaps (e.g., contraception efficacy), contraception preferences and past experiences, interpersonal relationship influences, and vulnerability to clinic and shelter-specific barriers. These findings may ultimately inform contraception interventions in partnership with the community of US women who experience homelessness and the health care and social service organizations who serve them.

The Implementation of an Interpersonal Violence Screening Program in Primary Care Settings: Lessons Learned.

BACKGROUND: Interpersonal violence (IPV) is a public health issue that disproportionately affects women. IPV screening improves likelihood of survivor disclosure and access to additional support. To enhance primary care IPV screening, Technology Enhanced Screening and Supportive Assistance (TESSA) uses integrated technological systems to deliver bidirectional, evidence-informed health navigation, health management, and safety interventions. This study evaluates TESSA implementation in primary care clinics using the Consolidated Framework for Implementation Research (CFIR). METHOD: CFIR is a metatheoretical framework used for evaluating clinical intervention implementation. Salient constructs within CFIR's five domains (intervention characteristics, outer setting, inner setting, characteristics of individuals, and process) were identified (23 constructs), and pertinent implementation details were examined. RESULTS: Key lessons learned included intervention characteristic constructs like intervention source (e.g., selecting tablets that can screen for items integral to the program's aims) and adaptability (e.g., ensuring tablets worked with electronic medical records for each clinic), process constructs like engaging champions (e.g., garnering buy-in from key clinic stakeholders and staff), outer setting constructs like patient needs and resources (e.g., addressing pertinent patient resource needs) and external policies and incentives (e.g., incentivizing clinics by addressing clinic needs), and inner setting constructs like leadership engagement (e.g., ensuring buy-in from organizational leaders as leadership changed frequently). CONCLUSIONS: CFIR identifies important implementation factors for programs like TESSA that screen for high-risk populations and implement in primary care settings. The TESSA program implementation permits increased IPV screening among primary health care populations, thus promoting access to resources for otherwise hard-to-reach populations.

Development and implementation of tablet-based screening for interpersonal violence in primary care settings.

Technology Enhanced Screening and Supportive Assistance (TESSA) is program that includes a patient-facing mobile web app designed to identify primary care patients with a history of interpersonal violence (IPV). The implementation study included 1495 participants screened. Approximately one in four reported experiences with intimate partner violence (29%) or sexual assault (24%). Among those offered health advocacy services based on their victimization experiences, 31% indicated they wished to accept the assistance. We conclude that a tablet-based self-screening tool in primary care clinics is a viable way to identify and offer services to people who have experienced interpersonal violence.

The Effectiveness of High-Flow Nasal Oxygen During the Intraoperative Period: A Systematic Review and Meta-analysis.

BACKGROUND: High-flow nasal oxygen (HFNO) is increasingly being used in intensive care units for management of hypoxemia and respiratory failure. However, the effectiveness of HFNO for preventing hypoxemia in the intraoperative period is unclear. The purpose of this systematic review was to compare patient oxygenation and end-tidal CO2 (EtCO2), between HFNO and conventional oxygenation, during the intraoperative period in surgical patients. METHODS: Standard databases were searched from inception to February 2020. Studies involving intraoperative use of HFNO with 1 of the 4 outcomes: (1) oxygen (O2) desaturation, (2) minimum O2 saturation, (3) safe apnea time, or (4) EtCO2 were included. Intraoperative period was divided into 2 phases: at induction with general anesthesia and during surgical procedure under sedation without tracheal intubation. RESULTS: Eight randomized controlled trials (RCTs; 4 induction, 4 procedure, 2314 patients) were included for systematic review and meta-analyses. We found the risk of intraoperative O2 desaturation was lower in HFNO versus conventional oxygenation control group; at induction with an odds ratio (OR; 95% confidence interval [CI]) of 0.06 (0.01-0.59, P = .02), and during procedure, OR (95% CI) of 0.09 (0.05-0.18; P < .001). The minimum O2 saturation was higher in HFNO versus conventional oxygenation; at induction by a mean difference (MD) (95% CI) of 5.1% (3.3-6.9; P < .001), and during procedure, by a MD (95% CI) of 4.0% (1.8-6.2; P < .001). Safe apnea time at induction was longer in HFNO versus conventional oxygenation by a MD (95% CI) of 33.4 seconds (16.8-50.1; P < .001). EtCO2 at induction was not significantly different between HFNO and conventional oxygenation groups. CONCLUSIONS: This systematic review and meta-analysis show that, in the intraoperative setting, HFNO compared to conventional oxygenation reduces the risk of O2 desaturation, increases minimum O2 saturation, and safe apnea time. HFNO should be considered for anesthesia induction and during surgical procedures under sedation without tracheal intubation in patients at higher risk of hypoxemia.

What's theory got to do with it: measuring effects of theory on lifestyle behaviors and weight in the Better Me Within Randomized Trial.

Background: Knowing which theoretical constructs work best to design effective interventions is essential for populations with increased disease burden. African American women (AAW) experience greater prevalence of chronic diseases and fewer benefits from weight loss interventions compared to White women. Purpose: To examine how theoretical constructs were associated with lifestyle behaviors and weight outcomes in the Better Me Within (BMW) Randomized Trial. Methods: BMW used a tailored diabetes prevention program implemented in churches among AAW with BMI ≥ 25. Regression models assessed relationships between constructs (self-efficacy, social support and motivation), and outcomes (physical activity (PA), calories, and weight). Results: Among 221 AAW (mean (SD) age 48.8 years (11.2); mean weight 215.1 pounds (50.5), several significant relationships were found including an association between change in motivation for activity and change in PA (p=.003), and change in motivation for diet and weight at follow-up (p=<.001). Discussion: The clearest relationships emerged for PA with motivation for activity and weight management social support demonstrating significance in all models. Translation to Practice: Self-efficacy, motivation and social support show promise to promote changes in PA and weight among church-going AAW. Opportunities to keep engaging AAW in research are essential for eliminating health inequities in this population.

The Body in Crisis: A Health Needs Assessment among Female Survivors of Interpersonal Violence.

BACKGROUND: When women who experience violence seek social services, they are looking to meet immediate needs: shelter, safety, and support. Seeking assistance as part of a crisis may inadvertently detract attention away from other critical needs. Literature illustrates the emotional and physical effects of violence on women's bodies, as well as their long-term health. While health may present as an urgent need in cases of serious injury, it is often overlooked in crisis-oriented service delivery systems. This study explored the experience with violence, health status, and holistic healthcare needs among women accessing interpersonal violence services in Texas. METHODS: A tablet-based survey was conducted at a family justice center, rape crisis center, and emergency shelter among women (N = 99) in Fort Worth, Texas. Survey questions assessed the participants' demographic information, health status, health needs, healthcare utilization, barriers to accessing healthcare, and experience with interpersonal violence among participating women. RESULTS: Two-thirds of the sample reported suffering injuries from victimization experiences. More than half of the sample (62%) reported they went to the emergency room at least one time in the last 6 months, with 11 women reported staying five or more nights in the hospital in the last 6 months. Participants described urgent (e.g., advised by healthcare provider, too serious for a clinic) and non-urgent (e.g., not having another source of care, closest provider) reasons for using the emergency room. Roughly, half of the sample (50%) reported having at least three chronic conditions. DISCUSSION: This study illustrated that women seeking interpersonal violence related (IPV) services have multiple unmet needs and lack adequate access to physical and mental health care. Since the majority of the sample was living in poverty, there are multiple costs and investments in the participants' health that were forgone for their survival. This study provides data in support of the development of health-related services for IPV survivors.

Evaluation of a School-Based Child Physical and Sexual Abuse Prevention Program.

BACKGROUND: Evidence-based child sexual and physical abuse prevention programs delivered in schools are needed and require rigorous evaluation of program effects prior to widespread dissemination. The Play it Safe! program is a one-time session delivered by trained facilitators to teach students about recognizing, resisting, and reporting abuse. AIMS: To evaluate a school-based child sexual and physical abuse prevention intervention Play it Safe! among elementary school students using a cluster randomized design. METHOD: Six elementary schools in Texas were matched on demographic characteristics, and then randomized to intervention or wait-list control groups. Participants included third to fifth graders (n = 539). Participants received the pretest assessing vignette-based knowledge of physical and sexual abuse prevention (14 items). The intervention group immediately had the program. One month later, both groups received a posttest using the same validated scale. Multilevel linear regression analyses were estimated, and interaction effects were used to evaluate the effect of Play it Safe! while controlling for other factors. RESULTS: A statistically significant interaction between the treatment group and time (b = 1.30, p < .01) indicated a greater increase in the knowledge score over time in the intervention group. Moderating effect of grade was also observed as the intervention tended to have less effect for fifth grade compared with third grade (b = -1.04, p = .01). CONCLUSION: This study provides evidence to support the efficacy of the Play it Safe! program for increasing children's physical and sexual abuse prevention knowledge and skills among a racially and ethnically diverse sample of elementary school students.

The Texas Community-Engagement Research Alliance Against COVID-19 in Disproportionately Affected Communities (TX CEAL) Consortium.

The coronavirus disease 2019 (COVID-19) pandemic requires urgent implementation of effective community-engaged strategies to enhance education, awareness, and inclusion of underserved communities in prevention, mitigation, and treatment efforts. The Texas Community-Engagement Alliance Consortium was established with support from the United States' National Institutes of Health (NIH) to conduct community-engaged projects in selected geographic locations with a high proportion of medically underserved minority groups with a disproportionate burden of COVID-19 disease and hospitalizations. The purpose of this paper is to describe the development of the Consortium. The Consortium organized seven projects with focused activities to address COVID-19 clinical and vaccine trials in highly affected counties, as well as critical statewide efforts. Five Texas counties (Bexar, Dallas, Harris, Hidalgo, and Tarrant) were chosen by NIH because of high concentrations of underserved minority communities, existing community infrastructure, ongoing efforts against COVID-19, and disproportionate burden of COVID-19. Policies and practices can contribute to disparities in COVID-19 risk, morbidity, and mortality. Community engagement is an essential element for effective public health strategies in medically underserved minority areas. Working with partners, the Consortium will use community engagement strategies to address COVID-19 disparities.

Implementation of the Texas Community-Engaged Statewide Consortium for the Prevention of COVID-19.

The Community Engagement Alliance (CEAL) Against COVID-19 Disparities aims to conduct community-engaged research and outreach. This paper describes the Texas CEAL Consortium's activities in the first year and evaluates progress. The Texas CEAL Consortium comprised seven projects. To evaluate the Texas CEAL Consortium's progress, we used components of the RE-AIM Framework. Evaluation included estimating the number of people reached for data collection and education activities (reach), individual project goals and progress (effectiveness), partnerships established and partner engagement (adoption), and outreach and education activities (implementation). During the one-year period, focus groups were conducted with 172 people and surveys with 2107 people across Texas. Partners represented various types of organizations, including 11 non-profit organizations, 4 academic institutions, 3 civic groups, 3 government agencies, 2 grassroots organizations, 2 faith-based organizations, 1 clinic, and 4 that were of other types. The main facets of implementation consisted of education activities and the development of trainings. Key recommendations for future consortiums relate to funding and research logistics and the value of strong community partnerships. The lessons learned in this first year of rapid deployment inform ongoing work by the Texas CEAL Consortium and future community-engaged projects.

Development and Validation of a Child Physical and Sexual Abuse Prevention Scale.

Objective: School-based child abuse primary prevention programs are delivered across the country; however, a validated measurement tool that is feasible to deliver to students is unavailable. The purpose of this study was to describe the development and validation of a measurement tool for knowledge and skills related to the primary prevention of child physical and sexual abuse. Methods: Two elementary schools and 404 students participated. Students completed 5 instruments: the Play it Safe!® scale, 2 scales related to abuse prevention, and 2 unrelated scales. For assessment of the convergent and divergent validity, correlations were estimated and corresponding p-values in SAS version 9.4. Results: For the Play it Safe!® scale, the mean score was 10.87 out of 14 potential points (SD = 2.73; higher scores = higher knowledge). The internal consistency of the scale was adequate with a Cronbach's alpha of 0.77. We found strong correlations for the 2 convergent validity scales, and weak correlations for the 2 divergent validity scales. Conclusions: This study demonstrates the divergent and convergent validity of a child abuse primary prevention knowledge scale that can be used in school-settings and can assist in the measurement of primary prevention knowledge.

Analyzing Predictors of Control Measures and Psychosocial Problems Associated with COVID-19 Pandemic: Evidence from Eight Countries.

COVID-19 has harshly impacted communities globally. This study provides relevant information for creating equitable policy interventions to combat the spread of COVID-19. This study aims to predict the knowledge, attitude, and practice (KAP) of the COVID-19 pandemic at a global level to determine control measures and psychosocial problems. A cross-sectional survey was conducted from July to October 2020 using an online questionnaire. Questionnaires were initially distributed to academicians worldwide. These participants distributed the survey among their social, professional, and personal groups. Responses were collected and analyzed from 67 countries, with a sample size of 3031. Finally, based on the number of respondents, eight countries, including Bangladesh, China, Japan, Malaysia, Mexico, Pakistan, the United States, and Zambia were rigorously analyzed. Specifically, questionnaire responses related to COVID-19 accessibility, behavior, knowledge, opinion, psychological health, and susceptibility were collected and analyzed. As per our analysis, age groups were found to be a primary determinant of behavior, knowledge, opinion, psychological health, and susceptibility scores. Gender was the second most influential determinant for all metrics except information about COVID-19 accessibility, for which education was the second most important determinant. Respondent profession was the third most important metric for all scores. Our findings suggest that health authorities must promote health educations, implement related policies to disseminate COVID-19-awareness that can prevent and control the spread of COVID-19 infection.

Dissemination of Evidence-Based School Asthma Management Programs: Piloting Asthma 411 in an Urban Texas School District.

BACKGROUND: The dissemination and implementation (D&I) of evidence-based initiative (EBIs) is critical to improved public health. The Asthma 411 EBI was piloted in Texas from 2013 to 2015. The pilot's evaluation assessed its effectiveness and identified approaches to support D&I of school-health EBIs. METHODS: The pilot study was conducted in two schools; service categories included: a consulting physician, enhanced school asthma services, and support for links to community health resources. Data was collected on Emergency Medical Service (EMS) calls, aggregated nursing services, demographic characteristics, availability of medication provided through existing policies, and informal interviews. RESULTS: During the pilot, school-day asthma-related Emergency Medical Service (EMS) calls were eliminated. Documented asthma self-management education, authorization for rescue medication, and efforts to communicate with parents and health providers increased. Between year-1 and year-2, the gap between unadjusted, weighted mean absences among students with and without asthma was reduced by 1.1 days. However, this difference was not seen in a fully adjusted negative, binomial regression model. CONCLUSIONS: Evaluation of the Asthma 411 pilot suggests many EBI benefits were retained and identifies factors that may facilitate D&I of school health EBIs. Future research will clarify impacts on absenteeism and determine if observed benefits are sustained.

Optimal local anesthetic regimen for saddle block in ambulatory anorectal surgery: an evidence-based systematic review.

BACKGROUND: Ambulatory anorectal surgery requires an anesthetic of short duration but profound depth. Saddle block anesthesia (SBA) can provide dense sacral anesthesia with minimal motor blockade, but the ideal local anesthetic agent remains undefined. This systematic review aims to identify the optimal SBA regimen for ambulatory anorectal surgery. METHODS: We sought randomized trials examining SBA for ambulatory anorectal surgery and stratified patients into four subgroups according to local anesthetic type and dose: (1) longer acting, higher dose; (2) longer acting, lower dose; (3) shorter acting, higher dose; and (4) shorter acting, lower dose. Longer acting agents included bupivacaine and levobupivacaine; shorter acting agents included chloroprocaine, mepivacaine, and prilocaine. Lower dose was defined as ≤5 mg and ≤20 mg for longer and shorter acting local anesthetics, respectively. The primary outcome was time to discharge; secondary outcomes included times to sensory and motor block regression, urine voiding, and ambulation, as well as block success. RESULTS: A total of 11 trials (1063 patients) were included. Overall study quality and reporting consistency was poor. Doses ranged from 1.5-7.5 mg to 3-30 mg of longer and shorter acting local anesthetics, respectively. Hyperbaric local anesthetics were used in eight trials (953 patients, 86%). The median time to discharge appeared similar across all subgroups with an overall time of 182 (IQR 102) min. The use of long-acting, lower dose regimens was associated with a faster median time to motor block regression. Block success approached 99% among all trials. CONCLUSIONS: There is presently insufficient qualitative and quantitative evidence to identify an optimal SBA regimen for ambulatory anorectal surgery. Nonetheless, we found that doses as low as 1.5 and 3 mg of longer and shorter acting hyperbaric local anesthetics, respectively, can achieve effective and reliable SBA with timely hospital discharge. Despite similar discharge times, longer acting, lower dose local anesthetics may produce faster motor block regression following SBA for ambulatory anorectal surgery.

Use of a Health Advocacy Model for Survivors of Interpersonal Violence.

This article examines the implementation of a health advocacy model designed for survivors of interpersonal violence (IPV) in a metropolitan area of North Texas. Using a framework influenced by motivational interviewing, solution-focused therapy, and trauma-informed care, this program engaged IPV survivors in creating health and safety goals. Goal attainment scaling was used to track progress after each health advocacy encounter. Clients could set their own goals for healthcare, self-care, and safety. The program served 419 clients and 648 goals were set by clients at the first visit. Among all goals, 89% selected goals focused on healthcare, with 47% of those selecting obtaining health insurance or coverage as a need. These results demonstrate the need for an enhanced healthcare response for this population. The remaining goals selected were self-care (7%) and safety (3%). The design of the health advocacy intervention shows promise towards filling the gaps between IPV and healthcare service delivery systems.

Sham surgeries for central and peripheral neural injuries persistently enhance pain-avoidance behavior as revealed by an operant conflict test.

Studies using rodent models of neuropathic pain use sham surgery control procedures that cause deep tissue damage. Sham surgeries would thus be expected to induce potentially long-lasting postsurgical pain, but little evidence for such pain has been reported. Operant tests of voluntary behavior can reveal negative motivational and cognitive aspects of pain that may provide sensitive tools for detecting pain-related alterations. In a previously described operant mechanical conflict test involving lengthy familiarization and training, rodents freely choose to either escape from a brightly lit chamber by crossing sharp probes or refuse to cross. Here, we describe a brief (2-day) mechanical conflict protocol that exploits rats' innate exploratory response to a novel environment to detect persistently enhanced pain-avoidance behavior after sham surgeries for 2 neural injury models: thoracic spinal cord injury and chronic constriction injury of the sciatic nerve. Pitting the combined motivations to avoid the bright light and to explore the novel device against pain from crossing noxious probes disclosed a conflicting, hyperalgesia-related reluctance to repeatedly cross the probes after injury. Rats receiving standard sham surgeries demonstrated enhanced pain-like avoidance behavior compared with naive controls, and this behavior was similar to that of corresponding chronic constriction injury or spinal cord injury rats weeks or months after injury. In the case of sham surgery for spinal cord injury, video analysis of voluntary exploratory behavior directed at the probes revealed enhanced forepaw withdrawal responses. These findings have important implications for preclinical investigations into behavioral alterations and physiological mechanisms associated with postsurgical and neuropathic pain.

Haemangiopericytoma with no dural attachment.

The authors describe a case of a gentleman in his 40s who presented with a space-occupying lesion in the right precentral gyrus which showed no dural attachment and was well circumscribed, both on imaging and at surgery. This lesion was histologically challenging to diagnose but favoured to be a haemangiopericytoma. The lack of dural attachment is unusual for this tumour type but is typically associated with metastases to the brain, and less commonly a solid primary central nervous system tumour. The authors propose that haemangiopericytoma should be regularly considered as a differential diagnosis of cerebral metastases so that inadequate preoperative anticipation and planning is not encountered.
