Experience-Dependent Remodeling of Juvenile Brain Olfactory Sensory Neuron Synaptic Connectivity in an Early-Life Critical Period.

Early-life olfactory sensory experience induces dramatic synaptic glomeruli remodeling in the Drosophila juvenile brain, which is experientially dose-dependent, temporally restricted, and transiently reversible only in a short, well-defined critical period. The directionality of brain circuit synaptic connectivity remodeling is determined by the specific odorant acting on the respondent receptor class of olfactory sensory neurons. In general, each neuron class expresses only a single odorant receptor and innervates a single olfactory synaptic glomerulus. In the Drosophila genetic model, the full array of olfactory glomeruli has been precisely mapped by odorant responsiveness and behavioral output. Ethyl butyrate (EB) odorant activates Or42a receptor neurons innervating the VM7 glomerulus. During the early-life critical period, EB experience drives dose-dependent synapse elimination in the Or42a olfactory sensory neurons. Timed periods of dosed EB odorant exposure allow investigation of experience-dependent circuit connectivity pruning in juvenile brain. Confocal microscopy imaging of antennal lobe synaptic glomeruli is done with Or42a receptor-driven transgenic markers that provide quantification of synapse number and innervation volume. The sophisticated Drosophila genetic toolkit enables the systematic dissection of the cellular and molecular mechanisms mediating brain circuit remodeling.

Suicide Mortality Among Formerly Incarcerated People Compared With the General Population in North Carolina, 2000-2020.

We aimed to compare rates and characteristics of suicide mortality in formerly incarcerated people with those of the general population in North Carolina. We conducted a retrospective cohort study of 266,400 people released from North Carolina state prisons between January 1, 2000, and March 1, 2020. Using direct and indirect standardization by age, sex, and calendar year, we calculated standardized suicide mortality rates and standardized mortality ratios comparing formerly incarcerated people with the North Carolina general population. We evaluated effect modification by race/ethnicity, sex, age, and firearm involvement. Formerly incarcerated people had approximately twice the overall suicide mortality of the general population for 3 years after release, with the highest rate of suicide mortality being observed in the 2-week period after release. In contrast to patterns in the general population, formerly incarcerated people had higher rates of non-firearm-involved suicide mortality than firearm-involved suicide mortality. Formerly incarcerated female, White and Hispanic/Latino, and emerging adult people had a greater elevation of suicide mortality than their general-population peers compared with other groups. These findings suggest a need for long-term support for formerly incarcerated people as they return to community living and a need to identify opportunities for interventions that reduce the harms of incarceration for especially vulnerable groups.

Dietary fatty acids improve perceived sleep quality, stress, and health in migraine: a secondary analysis of a randomized controlled trial.

Background: Migraine is a prevalent disabling condition often associated with comorbid physical and psychological symptoms that contribute to impaired quality of life and disability. Studies suggest that increasing dietary omega-3 fatty acid is associated with headache reduction, but less is known about the effects on quality of life in migraine. Methods: After a 4-week run-in, 182 adults with 5-20 migraine days per month were randomized to one of the 3 arms for sixteen weeks. Dietary arms included: H3L6 (a high omega-3, low omega-6 diet), H3 (a high omega-3, an average omega-6 diet), or a control diet (average intakes of omega-3 and omega-6 fatty acids). Prespecified secondary endpoints included daily diary measures (stress perception, sleep quality, and perceived health), Patient-Reported Outcome Measurement Information System Version 1.0 ([PROMIS©) measures and the Migraine Disability Assessment (MIDAS). Analyses used linear mixed effects models to control for repeated measures. Results: The H3L6 diet was associated with significant improvements in stress perception [adjusted mean difference (aMD): -1.5 (95% confidence interval: -1.7 to -1.2)], sleep quality [aMD: 0.2 (95% CI:0.1-0.2)], and perceived health [aMD: 0.2 (0.2-0.3)] compared to the control. Similarly, the H3 diet was associated with significant improvements in stress perception [aMD: -0.8 (-1.1 to -0.5)], sleep quality [aMD: 0.2 (0.1, 0.3)], and perceived health [aMD: 0.3 (0.2, 0.3)] compared to the control. MIDAS scores improved substantially in the intervention groups compared with the control (H3L6 aMD: -11.8 [-25.1, 1.5] and H3 aMD: -10.7 [-24.0, 2.7]). Among the PROMIS-29 assessments, the biggest impact was on pain interference [H3L6 MD: -1.8 (-4.4, 0.7) and H3 aMD: -3.2 (-5.9, -0.5)] and pain intensity [H3L6 MD: -0.6 (-1.3, 0.1) and H3 aMD: -0.6 (-1.4, 0.1)]. Discussion: The diary measures, with their increased power, supported our hypothesis that symptoms associated with migraine attacks could be responsive to specific dietary fatty acid manipulations. Changes in the PROMIS© measures reflected improvements in non-headache pain as well as physical and psychological function, largely in the expected directions. These findings suggest that increasing omega-3 with or without decreasing omega-6 in the diet may represent a reasonable adjunctive approach to reducing symptoms associated with migraine attacks.

"We adjusted for race": now what? A systematic review of utilization and reporting of race in American Journal of Epidemiology and Epidemiology, 2020-2021.

Race is a social construct, commonly used in epidemiologic research to adjust for confounding. However, adjustment of race may mask racial disparities, thereby perpetuating structural racism. We conducted a systematic review of articles published in Epidemiology and American Journal of Epidemiology between 2020 and 2021 to (1) understand how race, ethnicity, and similar social constructs were operationalized, used, and reported; and (2) characterize good and poor practices of utilization and reporting of race data on the basis of the extent to which they reveal or mask systemic racism. Original research articles were considered for full review and data extraction if race data were used in the study analysis. We extracted how race was categorized, used-as a descriptor, confounder, or for effect measure modification (EMM)-and reported if the authors discussed racial disparities and systemic bias-related mechanisms responsible for perpetuating the disparities. Of the 561 articles, 299 had race data available and 192 (34.2%) used race data in analyses. Among the 160 US-based studies, 81 different racial categorizations were used. Race was most often used as a confounder (52%), followed by effect measure modifier (33%), and descriptive variable (12%). Fewer than 1 in 4 articles (22.9%) exhibited good practices (EMM along with discussing disparities and mechanisms), 63.5% of the articles exhibited poor practices (confounding only or not discussing mechanisms), and 13.5% were considered neither poor nor good practices. We discuss implications and provide 13 recommendations for operationalization, utilization, and reporting of race in epidemiologic and public health research.

Integrative medical group visits for patients with chronic pain: results of a pilot single-site hybrid implementation-effectiveness feasibility study.

Background: Approximately 20% of adults in the United States experience chronic pain. Integrative Medical Group Visit (IMGV) offers an innovative approach to chronic pain management through training in mindfulness, nutrition, and other mind-body techniques combined with peer support. To date, there are no studies on IMGV implementation, despite its promise as a feasible non-pharmacological intervention for chronic pain management. In this study, we assessed the feasibility of implementing IMGV and assessing its effectiveness for chronic pain. Methods: Implementation Mapping was used to develop and evaluate implementation strategies for IMGV. Strategies included disseminating educational materials, conducting ongoing training, and conducting educational meetings. IMGV was delivered by three healthcare providers: an allopathic physician, registered yoga teacher, and naturopathic physician. The effectiveness of IMGV on patient health outcomes was assessed through qualitative interviews and a Patient-Reported Outcomes Scale (PROMIS-29). Provider perspectives of acceptability, appropriateness, and feasibility were assessed through periodic reflections (group interviews reflecting on the process of implementation) and field notes. Paired t-tests were used to assess changes between scores at baseline and post intervention. Qualitative data were coded by three experienced qualitative researchers using thematic content analysis. Results: Of the initial 16 patients enrolled in research, 12 completed at least two sessions of the IMGV. Other than fatigue, there was no statistically significant difference between the pre- and post-scores. Patients reported high satisfaction with IMGV, noting the development of new skills for self-care and the supportive community of peers. Themes from patient interviews and periodic reflections included the feasibility of virtual delivery, patient perspectives on acceptability, provider perspectives of feasibility and acceptability, ease of recruitment, complexity of referral and scheduling process, balancing medical check-in with group engagement, and nursing staff availability. Conclusions: IMGV was feasible, acceptable, and effective from the perspectives of patients and providers. Although statistically significant differences were not observed for most PROMIS measures, qualitative results suggested that participants experienced increased social support and increased pain coping skills. Providers found implementation strategies effective, except for engaging nurses, due to staff being overwhelmed from the pandemic. Lessons learned from this pilot study can inform future research on implementation of IMGV.

Pilot Observational Study of Patient Reported Outcome Measures for Long COVID Patients in Virtual Integrative Medical Group Visits.

Background: Long COVID is a common, debilitating post-infectious illness for which effective management is unknown. Integrative Medical Group Visits (IMGV) are effective interventions for chronic conditions and could benefit Long COVID patients. More information is needed regarding existing patient reported outcome measures (PROMs) to evaluate efficacy of IMGV for Long COVID. Objective: This study assessed the feasibility of specific PROMS to evaluate IMGVs for Long COVID. Findings will inform future efficacy trials. Methods: The Perceived Stress Scale (PSS-10), General Anxiety Disorder two-question tool (GAD-2), Fibromyalgia Symptom Severity scale (SSS), and Measure Yourself Medical Outcome Profile (MYMOP®) were collected pre- and post-group by teleconferencing platform or telephone and compared using paired t-tests. Patients were recruited from a Long COVID specialty clinic where they participated in 2-hour - 8 weekly IMGV sessions online. Results: Twenty-seven participants enrolled and completed pre-group surveys. Fourteen participants were reachable by phone post-group and completed all pre and post PROMs (78.6% female, 71.4% non-Hispanic White, mean age 49). MYMOP® primary symptomatology was fatigue, shortness of breath and "brain fog". Symptoms decreased in interference when compared to pre-group levels (mean difference -1.3 [95% CI-2.2, -.5]). PSS scores decreased (-3.4 [95% CI -5.8, -1.1]), and GAD-2 mean difference was -1.43 (95% CI -3.12, .26). There were no changes in SSS scores of fatigue (-.21 [95% CI -.68,0.25]), waking unrefreshed (.00 [95%CI -.32, -.32]), or trouble thinking (-.21 [95% CI -.78,0.35]). Conclusion: All PROMs were feasible to administer via teleconferencing platform or telephone. The PSS, GAD-2 and MYMOP® are promising PROMs to track Long COVID symptomatology among IMGV participants. The SSS, while feasible to administer, did not change compared to baseline. Larger, controlled studies are needed to determine the efficacy of virtual IMGVs to address the needs of this large and growing population.

Accelerated epigenetic aging and myopenia in young adult cancer survivors.

BACKGROUND: Young adult cancer survivors experience early aging-related morbidities and mortality. Biological aging biomarkers may identify at-risk survivors and increase our understanding of mechanisms underlying this accelerated aging. METHODS: Using an observational study design, we cross-sectionally measured DNA methylation-based epigenetic age in young adult cancer survivors at a tertiary, academic state cancer hospital. Participants were a convenience sample of consecutively enrolled survivors of childhood, adolescent, and young adult cancers treated with either an anthracycline or alkylating agent, and who were at least 3 months post-treatment. Similarly aged healthy comparators were consecutively enrolled. Cancer treatment and treatment intensity were compared to DNA methylation-based epigenetic age and pace of aging. RESULTS: Sixty survivors (58 completing assessments, mean age 20.5 years, range 18-29) and 27 comparators (mean age 20 years, range 17-29) underwent DNA methylation measurement. Survivors were predominantly female (62%) and white (60%) and averaged nearly 6 years post-treatment (range 0.2-25 years). Both epigenetic age (AgeAccelGrim: 1.5 vs. -2.4, p < 0.0001; AgeAccelPheno 2.3 vs. -3.8, p = 0.0013) and pace of aging (DunedinPACE 0.99 vs. 0.83, p < 0.0001) were greater in survivors versus comparators. In case-case adjusted analysis, compared to survivors with normal muscle mass, myopenic survivors had higher AgeAccelGrim (2.2 years, 95% CI 0.02-4.33, p = 0.02), AgeAccelPheno (6.2 years, 2.36-10.09, p < 0.001), and DunedinPACE (0.11, 0.05-0.17, p < 0.001). CONCLUSIONS: Epigenetic age is older and pace of aging is faster in young adult cancer survivors compared to noncancer peers, which is evident in the early post-therapy period. Survivors with physiological impairment demonstrate greater epigenetic age advancement. Measures of epigenetic age may identify young adult survivors at higher risk for poor functional and health outcomes.

A Multidisciplinary Surgical Approach to Mediastinal Masses in Children.

The aim of this study is to demonstrate the safety and advantages of a multidisciplinary approach to surgical resection of mediastinal masses in children. Eight patients underwent resection of a mediastinal mass by a team involving both a pediatric general surgeon and pediatric cardiothoracic surgeon. One patient required rapid initiation of cardiopulmonary bypass to complete the tumor resection and repair an aortic injury that occurred when removing adherent tumor from the structure. Perioperative outcomes were excellent for all patients. This series shows that a multidisciplinary surgical approach can be potentially life saving.

Hurricane Florence and suicide mortality in North Carolina: a controlled interrupted time-series analysis.

BACKGROUND: Natural disasters are associated with increased mental health disorders and suicidal ideation; however, associations with suicide deaths are not well understood. We explored how Hurricane Florence, which made landfall in September 2018, may have impacted suicide deaths in North Carolina (NC). METHODS: We used publicly available NC death records data to estimate associations between Hurricane Florence and monthly suicide death rates using a controlled, interrupted time series analysis. Hurricane exposure was determined by using county-level support designations from the Federal Emergency Management Agency. We examined effect modification by sex, age group, and race/ethnicity. RESULTS: 8363 suicide deaths occurred between January 2014 and December 2019. The overall suicide death rate in NC between 2014 and 2019 was 15.53 per 100 000 person-years (95% CI 15.20 to 15.87). Post-Hurricane, there was a small, immediate increase in the suicide death rate among exposed counties (0.89/100 000 PY; 95% CI -2.69 to 4.48). Comparing exposed and unexposed counties, there was no sustained post-Hurricane Florence change in suicide death rate trends (0.02/100 000 PY per month; 95% CI -0.33 to 0.38). Relative to 2018, NC experienced a statewide decline in suicides in 2019. An immediate increase in suicide deaths in Hurricane-affected counties versus Hurricane-unaffected counties was observed among women, people under age 65 and non-Hispanic black individuals, but there was no sustained change in the months after Hurricane Florence. CONCLUSIONS: Although results did not indicate a strong post-Hurricane Florence impact on suicide rates, subgroup analysis suggests differential impacts of Hurricane Florence on several groups, warranting future follow-up.

Health-Related Quality of Life After Single Ventricle Palliation or Tetralogy of Fallot Repair.

Single ventricle (SV) cardiac lesions and tetralogy of Fallot (TOF) are both common forms of cyanotic congenital heart disease. With advances in perioperative care and longitudinal follow-up, survival of these patients has dramatically improved and the majority survive to adulthood. This study compares health-related quality of life (HRQoL) of adult SV and TOF patients to each other and the general population. HRQoL of all surviving, non-transplanted SV and TOF patients 21 years of age and older at our institution was assessed with the SF-36 questionnaire via phone. Additional data including demographic parameters and information related to comorbidities and healthcare utilization were also analyzed. Among 81 eligible SV patients and 207 TOF patients, 33 (41%) and 75 (36%) completed the SF-36 phone survey, respectively. The mean age of SV patients was 32 vs. 38 years in the TOF group (p=0.01). SV patients reported more hepatic, pulmonary, and renal comorbidities. TOF patients were more likely to complete advanced degrees and more likely to have children (p=0.03). SV physical functioning scores were worse compared to TOF. In other domains of the SF-36 questionnaire, SV and TOF scores were similar. Compared to the general population, both groups reported worse bodily pain and mental health, but other aspects of psychosocial and general health were comparable. Overall HRQoL is good for both SV and TOF patients through early and mid-adulthood. Some QoL metrics were modestly worse in the SV patients. While these patients may have some physical limitations, psychosocial wellbeing appears preserved.

Innovations in suicide prevention research (INSPIRE): a protocol for a population-based case-control study.

BACKGROUND: Suicide deaths have been increasing for the past 20 years in the USA resulting in 45 979 deaths in 2020, a 29% increase since 1999. Lack of data linkage between entities with potential to implement large suicide prevention initiatives (health insurers, health institutions and corrections) is a barrier to developing an integrated framework for suicide prevention. OBJECTIVES: Data linkage between death records and several large administrative datasets to (1) estimate associations between risk factors and suicide outcomes, (2) develop predictive algorithms and (3) establish long-term data linkage workflow to ensure ongoing suicide surveillance. METHODS: We will combine six data sources from North Carolina, the 10th most populous state in the USA, from 2006 onward, including death certificate records, violent deaths reporting system, large private health insurance claims data, Medicaid claims data, University of North Carolina electronic health records and data on justice involved individuals released from incarceration. We will determine the incidence of death from suicide, suicide attempts and ideation in the four subpopulations to establish benchmarks. We will use a nested case-control design with incidence density-matched population-based controls to (1) identify short-term and long-term risk factors associated with suicide attempts and mortality and (2) develop machine learning-based predictive algorithms to identify individuals at risk of suicide deaths. DISCUSSION: We will address gaps from prior studies by establishing an in-depth linked suicide surveillance system integrating multiple large, comprehensive databases that permit establishment of benchmarks, identification of predictors, evaluation of prevention efforts and establishment of long-term surveillance workflow protocols.

Acute Leukemia Classification Using Transcriptional Profiles From Low-Cost Nanopore mRNA Sequencing.

PURPOSE: Most cases of pediatric acute leukemia occur in low- and middle-income countries, where health centers lack the tools required for accurate diagnosis and disease classification. Recent research shows the robustness of using unbiased short-read RNA sequencing to classify genomic subtypes of acute leukemia. Compared with short-read sequencing, nanopore sequencing has low capital and consumable costs, making it suitable for use in locations with limited health infrastructure. MATERIALS AND METHODS: We show the feasibility of nanopore mRNA sequencing on 134 cryopreserved acute leukemia specimens (26 acute myeloid leukemia [AML], 73 B-lineage acute lymphoblastic leukemia [B-ALL], 34 T-lineage acute lymphoblastic leukemia, and one acute undifferentiated leukemia). Using multiple library preparation approaches, we generated long-read transcripts for each sample. We developed a novel composite classification approach to predict acute leukemia lineage and major B-ALL and AML molecular subtypes directly from gene expression profiles. RESULTS: We demonstrate accurate classification of acute leukemia samples into AML, B-ALL, or T-lineage acute lymphoblastic leukemia (96.2% of cases are classifiable with a probability of > 0.8, with 100% accuracy) and further classification into clinically actionable genomic subtypes using shallow RNA nanopore sequencing, with 96.2% accuracy for major AML subtypes and 94.1% accuracy for major B-lineage acute lymphoblastic leukemia subtypes. CONCLUSION: Transcriptional profiling of acute leukemia samples using nanopore technology for diagnostic classification is feasible and accurate, which has the potential to improve the accuracy of cancer diagnosis in low-resource settings.

Frail young adult cancer survivors experience poor health-related quality of life.

BACKGROUND: Young adult cancer survivors experience frailty and decreased muscle mass at rates equivalent to much older noncancer populations, which indicate accelerated aging. Although frailty and low muscle mass can be identified in survivors, their implications for health-related quality of life are not well understood. METHODS: Through a cross-sectional analysis of young adult cancer survivors, frailty was assessed with the Fried frailty phenotype and skeletal muscle mass in relation to functional and quality of life outcomes measured by the Medical Outcomes Survey Short-Form 36 (SF-36). z tests compared survivors with US population means, and multivariable linear regression models estimated mean SF-36 scores by frailty and muscle mass with adjustments made for comorbidities, sex, and time from treatment. RESULTS: Sixty survivors (median age, 21 years; range, 18-29) participated in the study. Twenty-five (42%) had low muscle mass, and 25 were either frail or prefrail. Compared with US population means, survivors reported worse health and functional impairments across SF-36 domains that were more common among survivors with (pre)frailty or low muscle mass. In multivariable linear modeling, (pre)frail survivors (vs nonfrail) exhibited lower mean scores for general health (-9.1; P = .05), physical function (-14.9; P < .01), and overall physical health (-5.6; P = .02) independent of comorbid conditions. CONCLUSIONS: Measures of frailty and skeletal muscle mass identify subgroups of young adult cancer survivors with significantly impaired health, functional status, and quality of life independent of medical comorbidities. Identifying survivors with frailty or low muscle mass may provide opportunities for interventions to prevent functional and health declines or to reverse this process. LAY SUMMARY: Young adult cancer survivors age more quickly than peers without cancer, which is evidenced by a syndrome of decreased resilience known as frailty. The relationship between frailty (and one of its common components, decreased muscle mass) and quality of life among young adult cancer survivors was examined. Measuring decreased muscle mass and frailty identifies young survivors with poor quality of life, including worse general health, fatigue, physical function, and overall physical health, compared with nonfrail survivors. Interventions to address components of frailty (low muscle mass and weakness) may improve function and quality of life among young adult cancer survivors.

Guilt and Burnout in Medical Students.

THEORY: Burnout is prevalent among medical students and is correlated with negative feelings, behaviors, and outcomes. Empathy is a desired trait for medical students that has been correlated with reduced burnout. The concept of guilt is closely related to concern about the well-being of others; therefore, feelings of guilt may be associated with empathy. Excessive guilt poses an increased risk for internalized distress, symptoms such as anhedonia, and may be related to burnout. The relationship between pathogenic guilt and burnout in medical students is unknown. HYPOTHESIS: We hypothesize that pathogenic guilt is present and related to both burnout and empathy in medical students. METHODS: We conducted a cross-sectional survey study of all students in one medical school. Data were collected in February 2020. The Oldenburg Burnout Inventory (OBLI), Toronto Empathy Questionnaire (TEQ), and Interpersonal Guilt Questionaire-67 (IGQ-67) were used. A modified version of IGQ-67 was used to measure four subscales of pathogenic guilt: survival guilt, separation guilt, omnipotence guilt, and self-hate guilt. Data analyses for this study including screening, evaluation of assumptions, descriptive statistics, reliabilities, one-way ANOVA, and correlation coefficients, were conducted using SPSS version 26. RESULTS: Of 300, 168 (56.0%) students participated in the study. Survival, omnipotence, and self-hate classes of pathogenic guilt were positively correlated with burnout. Empathy was correlated with two classes of pathogenic guilt: survival and omnipotence. Empathy was inversely related to burnout (disengagement). CONCLUSIONS: Pathogenic guilt may be a contributor to burnout in medical students. Guilt should be a target of prevention and treatment in burnout in medical students.Supplemental data for this article is available online at https://doi.org/10.1080/10401334.2021.1891544.

Dietary alteration of n-3 and n-6 fatty acids for headache reduction in adults with migraine: randomized controlled trial.

OBJECTIVE: To determine whether dietary interventions that increase n-3 fatty acids with and without reduction in n-6 linoleic acid can alter circulating lipid mediators implicated in headache pathogenesis, and decrease headache in adults with migraine. DESIGN: Three arm, parallel group, randomized, modified double blind, controlled trial. SETTING: Ambulatory, academic medical center in the United States over 16 weeks. PARTICIPANTS: 182 participants (88% women, mean age 38 years) with migraines on 5-20 days per month (67% met criteria for chronic migraine). INTERVENTIONS: Three diets designed with eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), and linoleic acid altered as controlled variables: H3 diet (n=61)-increase EPA+DHA to 1.5 g/day and maintain linoleic acid at around 7% of energy; H3-L6 diet (n=61)-increase n-3 EPA+DHA to 1.5 g/day and decrease linoleic acid to ≤1.8% of energy; control diet (n=60)-maintain EPA+DHA at <150 mg/day and linoleic acid at around 7% of energy. All participants received foods accounting for two thirds of daily food energy and continued usual care. MAIN OUTCOME MEASURES: The primary endpoints (week 16) were the antinociceptive mediator 17-hydroxydocosahexaenoic acid (17-HDHA) in blood and the headache impact test (HIT-6), a six item questionnaire assessing headache impact on quality of life. Headache frequency was assessed daily with an electronic diary. RESULTS: In intention-to-treat analyses (n=182), the H3-L6 and H3 diets increased circulating 17-HDHA (log ng/mL) compared with the control diet (baseline-adjusted mean difference 0.6, 95% confidence interval 0.2 to 0.9; 0.7, 0.4 to 1.1, respectively). The observed improvement in HIT-6 scores in the H3-L6 and H3 groups was not statistically significant (-1.6, -4.2 to 1.0, and -1.5, -4.2 to 1.2, respectively). Compared with the control diet, the H3-L6 and H3 diets decreased total headache hours per day (-1.7, -2.5 to -0.9, and -1.3, -2.1 to -0.5, respectively), moderate to severe headache hours per day (-0.8, -1.2 to -0.4, and -0.7, -1.1 to -0.3, respectively), and headache days per month (-4.0, -5.2 to -2.7, and -2.0, -3.3 to -0.7, respectively). The H3-L6 diet decreased headache days per month more than the H3 diet (-2.0, -3.2 to -0.8), suggesting additional benefit from lowering dietary linoleic acid. The H3-L6 and H3 diets altered n-3 and n-6 fatty acids and several of their nociceptive oxylipin derivatives in plasma, serum, erythrocytes or immune cells, but did not alter classic headache mediators calcitonin gene related peptide and prostaglandin E2. CONCLUSIONS: The H3-L6 and H3 interventions altered bioactive mediators implicated in headache pathogenesis and decreased frequency and severity of headaches, but did not significantly improve quality of life.

Feasibility of Implementation Mapping for Integrative Medical Group Visits.

Objectives: Implementation science is key to translating complementary and integrative health intervention research into practice as it can increase accessibility and affordability while maximizing patient health outcomes. The authors describe using implementation mapping to (1) identify barriers and facilitators impacting the implementation of an Integrative Medical Group Visit (IMGV) intervention in an outpatient setting with a high burden of patients with chronic pain and (2) select and develop implementation strategies utilizing theory and stakeholder input to address those barriers and facilitators. Design: The authors selected a packaged, evidence-based, integrative pain management intervention, the IMGV, to implement in an outpatient clinic with a high burden of patients with chronic pain. The authors used implementation mapping to identify implementation strategies for IMGV, considering theory and stakeholder input. Stakeholder interviews with clinic staff, faculty, and administrators (n = 15) were guided by the Consolidated Framework for Implementation Research. Results: Based on interview data, the authors identified administrators, physicians, nursing staff, and scheduling staff as key stakeholders involved in implementation. Barriers and facilitators focused on knowledge, buy-in, and operational procedures needed to successfully implement IMGV. The implementation team identified three cognitive influences on behavior that would impact performance: knowledge, outcome expectations, and self-efficacy; and three theoretical change methods: cue to participate, communication, and mobilization. Implementation strategies identified included identifying and preparing champions, participation in ongoing training, developing and distributing educational materials, and organizing clinician implementation team meetings. Conclusions: This study provides an example of the application of implementation mapping to identify theory-driven implementation strategies for IMGV. Implementation mapping is a feasible method that may be useful in providing a guiding structure for implementation teams as they employ implementation frameworks and select implementation strategies for integrative health interventions.

COVID-19 surveillance and Black American substance use disorder: An examination of data and policy.

Research has cited structural racism as a determinate of black Americans' susceptibility to COVID-19. Using the flu surveillance system as a template, the U.S. has collected surveillance data on COVID-19. The U.S. also has rich databases on drug use and treatment. The U.S. should use data, combined with epidemiologic modeling that includes accurate proxies for structural racism, to direct policy, treatment, and COVID-19 vaccine distribution priorities. This paper provides a baseline of where we are and suggestions to consider to achieve health parity in populations of color.

Gender Differences in Cardiothoracic Surgery Interest Among General Surgery Applicants.

BACKGROUND: Although the overall gender gap in medicine is narrowing, significant gender disparities remain in the cardiothoracic surgery (CTS) field; women represent only 7% of practicing surgeons and 20% of residents. The purpose of this study was to identify gender differences in CTS exposure and interest among fourth year medical students applying to general surgery residency. METHODS: An anonymous survey was emailed to general surgery residency applicants at a major academic program for the 2019 and 2020 application cycles. Data were stratified by gender and analyzed using the χ2 and t tests. RESULTS: Of the 303 responders to the survey, 44% were women. A total of 58% of women were unlikely to be interested in or were definitely not interested in pursuing a career in CTS compared with 35% of men (P < .05). Men were 2.5 times more likely than women to be interested in CTS (odds ratio, 2.5; 95% confidence interval, 1.5 to 4.1). More men had rotated through CTS (55% vs 44%; P = .04) and shadowed a cardiothoracic surgeon (41% vs 29%; P = .03). More than 30% of women interested in CTS reported mentorship as the most important factor in their decision. Mentorship and CTS rotations were both independently associated with CTS interest after adjusting for gender. CONCLUSIONS: Interest in CTS is disappointingly low among women and represents a troublesome disparity that must be addressed. Early exposure to CTS and more mentorship from cardiothoracic surgeons are critical to reverse the current trend. Further studies are necessary to determine factors limiting female exposure to CTS rotations and dissuading female applicants from pursuing careers in CTS.

Comparing prospective headache diary and retrospective four-week headache questionnaire over 20 weeks: Secondary data analysis from a randomized controlled trial.

BACKGROUND: Headache diaries and recall questionnaires are frequently used to assess headache frequency and severity in clinical and research settings. METHODS: Using 20 weeks of data from an intervention trial with 182 participants, we evaluated concordance between an electronic headache diary administered on a daily basis and designed to capture the presence and severity of headaches on an hourly basis (the headache diary) and a recall questionnaire, with retrospective estimation of the number of headache days assessed on a monthly basis. We further examined whether the duration or severity of headaches assessed by the electronic diary impacted concordance between these two measures. RESULTS: Over the course of four 28-day periods, people with migraine participating in a dietary intervention reported an average of 13.7 and 11.1 headache days in the headache diary and recall questionnaire, respectively. CONCLUSION: Over time, the concordance between headache days reported in these two measures tended to increase; however, the recall questionnaire headache estimates were lower than the diary measures in all four periods. When analysis was restricted to headaches lasting 8 hours or more, the number of headache days was more closely aligned with days reported in the recall questionnaire, indicating that the accuracy of recall estimates is likely to be influenced by headache duration. Restriction of analyses to moderate-to-severe headaches did not change results as much as headache duration. The findings indicate that recall questionnaires administered on a monthly basis may underestimate headache frequency and therefore should not be used interchangeably with headache diaries.Clinical Trials.gov Identifier: NCT02012790.
