BACKGROUND: The E.U.'s lack of racially disaggregated data impedes the formulation of effective interventions, and crises such as Covid-19 may continue to impact minorities more severely. Our predictive model offers insight into the disparate ways in which Covid-19 has likely impacted E.U. minorities and allows for the inference of differences in Covid-19 infection and death rates between E.U. minority and non-minority populations. METHODS: Data covering Covid-19, social determinants of health and minority status were included from 1 March 2020 to 28 February 2021. A systematic comparison of US and E.U. states enabled the projection of Covid-19 infection and death rates for minorities and non-minorities in E.U. states. RESULTS: The model predicted Covid-19 infection rates with 95-100% accuracy for 23 out of 28 E.U. states. Projections for Covid-19 infection and mortality rates among E.U. minority groups illustrate parallel trends to US rates. CONCLUSIONS: Disparities in Covid-19 infection and death rates by minority status likely exist in patterns similar to those observed in US data. Policy Implications: Collecting data by race/ethnicity in the E.U. would help document health disparities and craft more targeted health interventions and mitigation strategies.

Aim: To analyze the predictive value of biochemical liver tests in patients with malignant melanoma, breast, colorectal or lung cancers at the time of diagnosis of liver metastases. Methods: A retrospective review of patients with the above-mentioned solid tumors at MedStar Georgetown University Hospital from 2016-2020. Results: The highest optimal cutoff according to sensitivity and specificity for the presence of liver metastases was for AST ≥1.5 × ULN for melanoma, lung, and breast cancers and ≥2 × ULN for colorectal cancer, ALT ≥1.25 × ULN for melanoma, breast and colorectal cancers and ≥1.5 × ULN for lung cancer, and ALP ≥1.5 × ULN for melanoma, breast and colorectal cancers. Conclusion: Using thresholds of liver enzymes above the ULN may improve the diagnostic accuracy for the presence of liver metastases.

OBJECTIVE: The purpose of this study is to understand change in parent-reported outcomes of mental health symptoms, health-related quality of life (QoL), and school-related functioning among children receiving mental health care at 3 federally qualified health centers engaging in a comprehensive pediatric mental health integration model. METHODS: Trained personnel enrolled English- or Spanish-speaking families of 6- to 12-year-old children who had recently started receiving integrated mental health care and surveyed their parent/caregiver at 3 time points: entry into the cohort, 6-month follow-up, and 12-month follow-up (unique N = 51). Primary outcomes included validated measures of child symptoms, child health-related QoL, and child school-related functioning. Secondary outcomes focused on parental functioning and included validated measures of parental stress and depressive and internalizing symptoms. A multilevel mixed-effects generalized linear model was used to estimate the change in parent-reported outcomes over time, with inverse probability weights used to address attrition. Additional analyses were conducted to determine the degree to which changes in symptoms over time were associated with improvements in school-related functioning. RESULTS: Over 12 months, children's mental health symptoms, health-related QoL, and school-related functional outcomes significantly improved. No changes in parental functioning were observed. In addition, improvements in mental health symptoms and health-related QoL were associated with improvements in school-related functional outcomes over time. CONCLUSION: Findings demonstrate that outcomes of children who received integrated mental health care improved over time, both in regard to mental health and school functioning.

Abnormal liver tests are one of the most common challenges in the primary care setting. Primary care practitioners order these tests for numerous reasons, including investigating abdominal signs and symptoms or suspected alcohol-use disorder, or to determine medication adverse effects. Evaluation should be guided by both the clinical presentation and the pattern of injury. In this article, we will focus on the epidemiology, pathophysiology, clinical presentation, diagnostic work-up, and management of elevated liver enzymes, with an emphasis on the most common causes of abnormal liver testing.

OBJECTIVES: To examine associations between factors associated with loss to follow-up and effectiveness in the TelAbortion project, which provided medication abortion by direct-to-patient telemedicine and mail in the United States. STUDY DESIGN: The study population for this descriptive analysis included abortions among participants enrolled in the TelAbortion study with data present in a web-based database tool from November 2018 to September 2021 who were mailed a medication package. The analysis included information on abortions across nine sites. In this analysis, we used generalized estimating equations to examine factors associated with loss to follow-up and effectiveness. RESULTS: Of the 1831 abortions included in this analysis, 1553 (84.8%) were classified as having complete follow-up and 278 (15.2%) were classified as lost to follow-up. In a multivariable analysis, factors significantly associated with loss to follow-up included history of medical abortion, education, gestational age, study site, and whether the TelAbortion was performed pre- or post-COVID-19 onset (p < 0.05). The rate of treatment failure (i.e., abortions resulting in continuing pregnancy or uterine evacuation) reported in this study was 5.1%. The only covariate associated with both loss to follow-up and treatment failure was higher gestational age. However, using gestational age to impute missing abortion outcomes did not substantially change the estimated failure rate. CONCLUSIONS: Abortions that were lost to follow-up differed substantially from those with complete follow-up, which could bias the effectiveness estimate. However, imputing outcomes based on available and appropriate pretreatment data did not substantially affect the estimate. This finding is encouraging, although it does not exclude the possibility of bias due to unmeasured factors. IMPLICATIONS: Significant differences between abortion cases with complete follow-up and those lost to follow-up provide insights into abortion cases that may be at a higher risk for being lost. The low treatment failure rate indicates that the telemedicine provision of medication abortion is effective.

PURPOSE: We examine the use of transvaginal sonography in imaging ovarian follicles among non-pregnant reproductive-aged women enrolled in a contraceptive clinical trial. METHODS: Ten sites conducted a clinical trial comparing three oral ulipristal acetate regimens for ovulation inhibition. Enrollees underwent twice weekly transvaginal sonography and hormonal blood testing throughout treatment and until the second menses post-treatment. The primary outcome of the present analysis was success in identifying follicles ≥10 mm in a subgroup of sonograms performed at times of likely follicular activity (estradiol <100 pg/ml and progesterone >3 ng/ml). Secondarily, an overall analysis assessed all sonograms regardless of timing. RESULTS: At times of likely follicular activity, 135 women underwent 969 sonograms. The proportion of sonograms without follicles ≥10 mm ranged from 8.3% to 46.3% when stratified by site (p = .01). The odds of no follicle among higher-body mass index (BMI) women were 1.91 times those among lower-BMI women after controlling for site and treatment arm (95% CI: 1.13, 3.22). Results were similar for the overall population. CONCLUSION: Sonographers were less likely to identify follicles for higher-BMI women and results varied by site. Machine quality slightly impacted sonogram results, but did not sufficiently explain site differences.

This study explores healthcare professionals' perspectives about the impact of behavioral health integration (BHI) on pediatric primary care delivery in community health centers (CHCs). A concurrent, qualitative-dominant mixed methods empirical study design was utilized, applying semi-structured interviews with healthcare professionals at the end of the implementation phase of a 3-year co-development, implementation, and evaluation process. Surveys were also administered at three time points. Via thematic analysis, emergent qualitative themes were mapped onto the Relational Coordination (RC) conceptual framework to triangulate and complement final qualitative results with quantitative results. Interview findings reveal five emergent themes aligning with RC domains. Survey results show that healthcare professionals reported increased behavioral healthcare integration into clinic practice (p = 0.0002) and increased clinic readiness to address behavioral health needs (p = 0.0010). Effective pediatric BHI and care delivery at CHCs may rely on strong professional relationships and communication. Additional research from the patient/caregiver perspective is needed.

BACKGROUND: Research supports integrated pediatric behavioral health (BH), but evidence gaps remain in ensuring equitable care for children of all ages. In response, an interdisciplinary team codeveloped a stepped care model that expands BH services at 3 federally qualified health centers (FQHCs). METHODS: FQHCs reported monthly electronic medical record data regarding detection of BH issues, receipt of services, and psychotropic medications. Study staff reviewed charts of children with attention-deficit/hyperactivity disorder (ADHD) before and after implementation. RESULTS: Across 47 437 well-child visits, >80% included a complete BH screen, significantly higher than the state's long-term average (67.5%; P < .001). Primary care providers identified >30% of children as having BH issues. Of these, 11.2% of children <5 years, 53.8% of 5-12 years, and 74.6% >12 years were referred for care. Children seen by BH staff on the day of referral (ie, "warm hand-off") were more likely to complete an additional BH visit than children seen later (hazard ratio = 1.37; P < .0001). There was no change in the proportion of children prescribed psychotropic medications, but polypharmacy declined (from 9.5% to 5.7%; P < .001). After implementation, diagnostic rates for ADHD more than doubled compared with baseline, follow-up with a clinician within 30 days of diagnosis increased (62.9% before vs 78.3% after; P = .03) and prescriptions for psychotropic medication decreased (61.4% before vs 43.9% after; P = .03). CONCLUSIONS: Adding to a growing literature, results demonstrate that integrated BH care can improve services for children of all ages in FQHCs that predominantly serve marginalized populations.

The gastrointestinal (GI) tract is an infrequent site of breast cancer metastasis, but it often poses a diagnostic challenge when it occurs. The symptoms of GI metastases are often nonspecific, and the endoscopic manifestations are variable, requiring tissue biopsies for histologic examination. We report 2 cases of breast cancer metastasizing to the GI tract: a case of human epidermal growth factor receptor 2-positive invasive ductal carcinoma that metastasized to the stomach, a rare location for this histologic subtype, and another case of invasive lobular cell carcinoma that metastasized to the colon with unusual findings of mucosal pallor and edema on colonoscopy.

Children in low-income families are at risk for delayed diagnosis of autism spectrum disorder (ASD). The cascade-of-care model, which examines steps of care for quality and efficacy, can identify lesions in the process for evaluation and diagnosis for children at risk for ASD. Little is known about predictors that influence key steps in this process. We performed a retrospective chart review of 110 children under age five years from an academic medical center with social communication concerns. We assessed predictors of age of referral for ASD diagnostic evaluation, time to diagnosis, and likelihood of diagnostic completion. Children with continuity of primary care were referred at an earlier age than those receiving primary care at multiple centers. Compared with children with missed visits, children attending all well-child visits had a shorter median time to diagnosis. These findings illustrate a need for primary medical homes to facilitate early and timely ASD evaluations.

LAY ABSTRACT: Little is known about parent experiences throughout the diagnostic process for autism or how these parent experiences may help explain the disparities that exist between Hispanic and non-Hispanic families in time-to-diagnosis among children identified as at risk for autism. The current study examined trajectories of parenting stress, coping, and perceived family impact over time, throughout the autism diagnostic process among Hispanic and non-Hispanic families. Hispanic families reported lower levels of parenting stress, coping, and negative family impact across time. Further, there were differences in the change in use of coping and the amount of negative family impact reported between Hispanic and non-Hispanic parents over time. These differences shed light on the unique experiences and strengths of Hispanic families demonstrate. Interventions that leverage those strengths and focus on education, empowerment, and resilience might be particularly beneficial for Hispanic families and may also better inform work to increase resilience.

The suppression of distracting information in order to focus on an actual cognitive goal is a key feature of executive functions. The use of brain imaging methods to investigate the underlying neurobiological brain activations that occur during conflict processing have demonstrated a strong involvement of the fronto-parietal attention network (FPAN). Surprisingly, the directional interconnections, their time courses and activations at different frequency bands remain to be elucidated, and thus, this constitutes the focus of this study. The shared information flow between brain areas of the FPAN is provided for frequency bands ranging from the theta to the lower gamma band (4-40 Hz). We employed an adaptation of the Simon task utilizing Magnetoencephalography (MEG). Granger causality was applied to investigate interconnections between the active brain regions, as well as their directionality. Following stimulus onset, the middle frontal precentral cortex and superior parietal cortex were significantly activated during conflict processing in a time window of between 300 to 600ms. Important differences in causality were found across frequency bands between processing of conflicting stimuli in the left as compared to the right visual hemifield. The exchange of information from and to the FPAN was most prominent in the beta band. Moreover, the anterior cingulate cortex and the anterior insula represented key areas for conflict monitoring, either by receiving input from other areas of the FPAN or by generating output themselves. This indicates that the salience network is at least partly involved in processing conflict information. The present study provides detailed insights into the underlying neural mechanisms of the FPAN, especially regarding its temporal characteristics and directional interconnections.

Importance: Early identification of autism spectrum disorder (ASD) is associated with improved cognitive and behavioral outcomes. Targeted strategies are needed to support equitable access to diagnostic services to ensure that children from low-income and racial/ethnic minority families receive the benefits of early ASD identification and treatment. Objective: To test the efficacy of family navigation (FN), an individually tailored, culturally informed care management strategy, to increase the likelihood of achieving diagnostic ascertainment among young children at risk for ASD. Design, Setting, and Participants: This randomized clinical trial of 249 families of children aged 15 to 27 months who had positive screening results for possible ASD was conducted in 11 urban primary care sites in 3 cities. Data collection occurred from February 24, 2015, through November 5, 2018. Statistical analysis was performed on an intent-to-treat basis from November 5, 2018, to July 27, 2020. Interventions: Families were randomized to FN or conventional care management (CCM). Families receiving FN were assigned a navigator who conducted community-based outreach to families to address structural barriers to care and support engagement in recommended services. Families receiving CCM were assigned to a care manager, who did limited telephone outreach. Families received FN or CCM after positive initial screening results and for 100 days after diagnostic ascertainment. Main Outcomes and Measures: The primary outcome, diagnostic ascertainment, was measured as the number of days from randomization to completion of the child's clinical developmental evaluation, when a diagnosis of ASD or other developmental disorder was determined. Results: Among 250 families randomized, 249 were included in the primary analysis (174 boys [69.9%]; mean [SD] age, 22.0 [3.5] months; 205 [82.3%] publicly insured; 233 [93.6%] non-White). Children who received FN had a greater likelihood of reaching diagnostic ascertainment over the course of 1 year (FN, 108 of 126 [85.7%]; CCM, 94 of 123 [76.4%]; unadjusted hazard ratio [HR], 1.39 [95% CI, 1.05-1.84]). Site (Boston, New Haven, and Philadelphia) and ethnicity (Hispanic vs non-Hispanic) moderated the effect of FN (treatment × site interaction; P = .03; Boston: HR, 2.07 [95% CI, 1.31-3.26]; New Haven: HR, 1.91 [95% CI, 0.94-3.89]; and Philadelphia: HR, 0.91 [95% CI, 0.60-1.37]) (treatment × ethnicity interaction; P < .001; Hispanic families: HR, 2.81 [95% CI, 2.23-3.54] vs non-Hispanic families: HR, 1.49 [95% CI, 1.45-1.53]). The magnitude of FN's effect was significantly greater among Hispanic families than among non-Hispanic families (diagnostic ascertainment among Hispanic families: FN, 90.9% [30 of 33], and CCM, 53.3% [16 of 30]; vs non-Hispanic families: FN, 89.7% [35 of 39], and CCM, 77.5% [31 of 40]). Conclusions and Relevance: Family navigation improved the likelihood of diagnostic ascertainment among children from racial/ethnic minority, low-income families who were detected as at risk for ASD in primary care. Results suggest differential effects of FN by site and ethnicity. Trial Registration: ClinicalTrials.gov Identifier: NCT02359084.

In the past two decades, many studies have shown the paradoxical efficacy of zolpidem, a hypnotic used to induce sleep, in transiently alleviating various disorders of consciousness such as traumatic brain injury (TBI), dystonia, and Parkinson's disease. The mechanism of action of this effect of zolpidem is of great research interest. In this case study, we use magnetoencephalography (MEG) to investigate a fully conscious, ex-coma patient who suffered from neurological difficulties for a few years due to traumatic brain injury. For a few years after injury, the patient was under medication with zolpidem that drastically improved his symptoms. MEG recordings taken before and after zolpidem showed a reduction in power in the theta-alpha (4-12 Hz) and lower beta (15-20 Hz) frequency bands. An increase in power after zolpidem intake was found in the higher beta/lower gamma (20-43 Hz) frequency band. Source level functional connectivity measured using weighted-phase lag index showed changes after zolpidem intake. Stronger connectivity between left frontal and temporal brain regions was observed. We report that zolpidem induces a change in MEG resting power and functional connectivity in the patient. MEG is an informative and sensitive tool to detect changes in brain activity for TBI.

OBJECTIVES: Vulvodynia is common and characterized by vulvar discomfort and pain. However, few studies have assessed hygienic practices in relation to onset. We investigated whether hygienic behaviors were associated with the onset of vulvodynia. MATERIALS AND METHODS: We assessed a self-reported history of personal hygienic behaviors, including wearing tight-fitting clothing, vulva care and genital washing, pubic hair removal, douching, and powdering, a year before first reported onset of vulvar pain among 213 clinically confirmed cases and a similar time period among 221 general population controls. RESULTS: Compared with women who reported never wearing tight-fitting jeans or pants, women wearing tight-fitting jeans or pants 4 or more times per week had twice the odds of vulvodynia (95% CI = 1.14-3.95). Relative to controls, women with vulvodynia were substantially less likely to report use of soaps and gels to cleanse the vulva (95% CI = 0.17-0.63). Among women who chose to remove pubic hair, those who removed pubic hair from the mons pubis compared with bikini-area only hair removal, were 74% more likely to have vulvodynia (95% CI = 1.05-2.89). Finally, compared with women who reported bikini-area only hair removal less than monthly, those who removed hair from the mons pubis weekly or more were nearly 2 times more likely to be vulvodynia cases (95% CI = 0.83-3.49). CONCLUSIONS: Wearing tight-fitting jeans or pants and removing hair from the mons pubis area were associated with increased odds of vulvodynia. Research on how hygienic practices could influence vulvar pain in larger and more temporally addressed populations is warranted.

There is growing interest in Family Navigation as an approach to improving access to care for children with autism spectrum disorder, yet little data exist on the implementation of Family Navigation. The aim of this study was to identify potential failures in implementing Family Navigation for children with autism spectrum disorder, using a failure modes and effects analysis. This mixed-methods study was set within a randomized controlled trial testing the effectiveness of Family Navigation in reducing the time from screening to diagnosis and treatment for autism spectrum disorder across three states. Using standard failure modes and effects analysis methodology, experts in Family Navigation for autism spectrum disorder (n = 9) rated potential failures in implementation on a 10-point scale in three categories: likelihood of the failure occurring, likelihood of not detecting the failure, and severity of failure. Ratings were then used to create a risk priority number for each failure. The failure modes and effects analysis detected five areas for potential "high priority" failures in implementation: (1) setting up community-based services, (2) initial family meeting, (3) training, (4) fidelity monitoring, and (5) attending testing appointments. Reasons for failure included families not receptive, scheduling, and insufficient training time. The process with the highest risk profile was "setting up community-based services." Failure in "attending testing appointment" was rated as the most severe potential failure. A number of potential failures in Family Navigation implementation-along with strategies for mitigation-were identified. These data can guide those working to implement Family Navigation for children with autism spectrum disorder.

Drug-induced liver injury (DILI), herbal-induced liver injury, and herbal and dietary supplement (HDS)-induced liver injury are an important aspect of drug safety. Knowledge regarding responsible drugs, mechanisms, risk factors, and the diagnostic tools to detect liver injury have continued to grow in the past year. This review highlights what we considered the most significant publications from among more than 1800 articles relating to liver injury from medications, herbal products, and dietary supplements in 2017 and 2018. The US Drug-Induced Liver Injury Network (DILIN) prospective study highlighted several areas of ongoing study, including the potential utility of human leukocyte antigens and microRNAs as DILI risk factors and new data on racial differences, the role of alcohol consumption, factors associated with prognosis, and updates on the clinical signatures of autoimmune DILI, thiopurines, and HDS agents. Novel data were also generated from the Spanish and Latin American DILI registries as well as from Chinese and Korean case series. A few new agents causing DILI were added to the growing list in the past 2 years, including sodium-glucose co-transporter-2 inhibitors, as were new aspects of chemotherapy-associated liver injury. A number of cases reported previously described hepatotoxins confirmed via the Roussel Uclaf Causality Assessment Method (RUCAM; e.g., norethisterone, methylprednisolone, glatiramer acetate) and/or the DILIN method (e.g., celecoxib, dimethyl fumarate). Additionally, much work centered on elucidating the pathophysiology of DILI, including the importance of bile salt export pumps and immune-mediated mechanisms. Finally, it must be noted that, while hundreds of new studies described DILI in 2017-2018, the quality of such reports must always be addressed. Björnsson reminds us to remain very critical of the data when addressing the future utility of a study, which is why it is so important to adhere to a standardized method such as RUCAM when determining DILI causality. While drug-induced hepatotoxicity remains a diagnosis of exclusion, the diverse array of publications that appeared in 2017 and 2018 provided important advances in our understanding of DILI, paving the way for our improved ability to make a more definitive diagnosis and risk assessment.

Due to its increasing prevalence, Type 2 diabetes mellitus (T2DM) represents a major health challenge for modern society. Despite it being of fundamental interest, only a few MRI studies have conducted statistical analyses to draw scientifically valid conclusions about the complex interplay of T2DM and its associated clinical, structural, functional, metabolite, as well as cognitive distortions. Therefore, a systematic review of 68 manuscripts, following the PRISMA guidelines, was conducted. Notably, although the associations between imaging, clinical, and cognitive variables are not fully homogeneous, findings show a clear trend towards a link between altered brain structure and a decline in cognitive processing ability. The results of the review highlight the heterogeneity of the methods used across manuscripts in terms of assessed clinical variables, imaging, and data analysis methods. This is particularly significant as, if the subjects' criteria are not carefully considered, results are easily prone to confounding factors.

Based on individual circadian cycles and associated cognitive rhythms, humans can be classified via standardised self-reports as being early (EC), late (LC) and intermediate (IC) chronotypes. Alterations in neural cortical structure underlying these chronotype differences have rarely been investigated and are the scope of this study. 16 healthy male ECs, 16 ICs and 16 LCs were measured with a 3 T MAGNETOM TIM TRIO (Siemens, Erlangen) scanner using a magnetization prepared rapid gradient echo sequence. Data were analysed by applying voxel-based morphometry (VBM) and vertex-wise cortical thickness (CTh) analysis. VBM analysis revealed that ECs showed significantly lower grey matter volumes bilateral in the lateral occipital cortex and the precuneus as compared to LCs, and in the right lingual gyrus, occipital fusiform gyrus and the occipital pole as compared to ICs. CTh findings showed lower grey matter volumes for ECs in the left anterior insula, precuneus, inferior parietal cortex, and right pars triangularis than for LCs, and in the right superior parietal gyrus than for ICs. These findings reveal that chronotype differences are associated with specific neural substrates of cortical thickness, surface areas, and folding. We conclude that this might be the basis for chronotype differences in behaviour and brain function. Furthermore, our results speak for the necessity of considering "chronotype" as a potentially modulating factor in all kinds of structural brain-imaging experiments.
