Curr Probl Diagn Radiol 2024; 53:600-605. [PMID: 38714392 PMCID: PMC11283936 DOI: 10.1067/j.cpradiol.2024.05.013] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/28/2024] [Accepted: 05/02/2024] [Indexed: 05/09/2024]
Abstract
RATIONALE AND OBJECTIVES Literature shows that discrimination has been pervasive in the field of medicine. The aim of this study was to collect experiences related to discrimination among US radiology residents, including type and source, as well as the residents' perception on lectures about discrimination and harassment. We also explored the barriers to reporting, and suggested strategies to overcome them. MATERIAL AND METHODS Following Institutional Review Board (IRB) approval, an online survey was sent to program directors and coordinators across the US, who were asked to forward the link to their radiology residents. A reminder email was sent over a period of 4 months. The participants were reassured the survey was confidential and anonymous. RESULTS Among the respondents, the most reported types of discrimination were based in gender, race and nationality, the majority of which not being reported. The most common perpetrators were attending radiologists, co-residents, technologists, and patients. The main barriers for reporting were fear of retaliation, confidentiality concerns, and skepticism about a positive outcome. CONCLUSION Our study examines some experiences of discrimination shared by residents during their training, with gender and race being the most common causes. This sheds light into a hidden and unspoken issue and highlights the need for more active discussions in radiology on microaggressions and implicit bias. Our data can guide future studies as well as residency programs to build effective strategies to address discrimination, aiming for sustainable changes.

Abstract
BACKGROUND Hypertension and diabetes are major risk factors for cardiovascular diseases, stroke, and chronic kidney disease (CKD). Disparities in hypertension control persist among Black and Hispanic adults and persons living in poverty in the United States. The "LINKED-HEARTS Program" (a Cardiometabolic Health Program LINKED with Community Health WorkErs and Mobile HeAlth TelemonitoRing To reduce Health DisparitieS"), is a multi-level intervention that includes home blood pressure (BP) monitoring (HBPM), blood glucose telemonitoring, and team-based care. This study aims to examine the effect of the LINKED-HEARTS Program intervention in improving BP control compared to enhanced usual care (EUC) and to evaluate the reach, adoption, sustainability, and cost-effectiveness of the program. METHODS Using a hybrid type I effectiveness-implementation design, 428 adults with uncontrolled hypertension (systolic BP ≥ 140 mm Hg) and diabetes or CKD will be recruited from 18 primary care practices, including community health centers, in Maryland. Using a cluster-randomized trial design, practices are randomly assigned to the LINKED-HEARTS intervention arm or EUC arm. Participants in the LINKED-HEARTS intervention arm receive training on HBPM, BP and glucose telemonitoring, and community health worker and pharmacist telehealth visits on lifestyle modification and medication management over 12 months. The primary outcome is the proportion of participants with controlled BP (<140/90 mm Hg) at 12 months. CONCLUSIONS The study tests a multi-level intervention to control multiple chronic diseases. Findings from the study may be leveraged to reduce disparities in the management and control of chronic diseases and make primary care more responsive to the needs of underserved populations. TRIAL REGISTRATION ClinicalTrials.gov. Identifier: NCT05321368.

Abstract
BACKGROUND Disparities in hypertension control are well documented but underaddressed. METHODS RICH LIFE (Reducing Inequities in Care of Hypertension: Lifestyle Improvement for Everyone) was a 2-arm, cluster randomized trial comparing the effect on blood pressure (BP) control (systolic BP ≤140 mm Hg, diastolic BP ≤90 mm Hg), patient activation, and disparities in BP control of 2 multilevel interventions, standard of care plus (SCP) and collaborative care/stepped care (CC/SC). SCP included BP measurement standardization, audit and feedback, and equity-leadership training. CC/SC added roles to address social or medical needs. Primary outcomes were BP control and patient activation at 12 months. Generalized estimating equations and mixed-effects regression models with fixed effects of time, intervention, and their interaction compared change in outcomes at 12 months from baseline. RESULTS A total of 1820 adults with uncontrolled BP and ≥1 other risk factors enrolled in the study. Their mean age was 60.3 years, and baseline BP was 152.3/85.5 mm Hg; 59.4% were women; 57.4% were Black, 33.2% were White, and 9.4% were Hispanic; 74% had hyperlipidemia; and 45.1% had type 2 diabetes. CC/SC did not improve BP control rates more than SCP. Both groups achieved statistically and clinically significant BP control rates at 12 months (CC/SC: 57.3% [95% CI, 52.7%-62.0%]; SCP: 56.7% [95% CI, 51.9%-61.5%]). Pairwise comparisons between racial and ethnic groups showed overall no significant differences in BP control at 12 months. Patients with coronary heart disease showed greater achievement of BP control in CC/SC than in SCP (64.0% [95% CI, 54.1%-73.9%] versus 50.8% [95% CI, 42.6%-59.0%]; P=0.04), as did patients in rural areas (67.3% [95% CI, 49.8%-84.8%] versus 47.8% [95% CI, 32.4%-63.2%]; P=0.01). Individuals in both arms experienced statistically and clinically significant reductions in mean systolic BP (CC/SC: -13.8 mm Hg [95% CI, -15.2 to -12.5]; SCP: -14.6 mm Hg [95% CI, -15.9 to -13.2]) and diastolic BP (CC/SC: -6.9 mm Hg [95% CI, -7.8 to -6.1]; SCP: -5.5 mm Hg [95% CI, -6.4 to -4.6]) over time. The difference in diastolic BP reduction between CC/SC and SCP over time was statistically significant (-1.4 mm Hg [95% CI, -2.6 to -0.2). Patient activation did not differ between arms. CC/SC showed greater improvements in patient ratings of chronic illness care (Patient Assessment of Chronic Illness Care score) over 12 months (0.12 [95% CI, 0.02-0.22]). CONCLUSIONS Adding a collaborative care team to enhanced standard of care did not improve BP control but did improve patient ratings of chronic illness care.

Abstract
In this paper, we introduce an analytic approach for assessing effects of multilevel interventions on disparity in health outcomes and health-related decision outcomes (i.e., a treatment decision made by a healthcare provider). We outline common challenges that are encountered in interventional health disparity research, including issues of effect scale and interpretation, choice of covariates for adjustment and its impact on effect magnitude, and the methodological challenges involved with studying decision-based outcomes. To address these challenges, we introduce total effects of interventions on disparity for the entire sample and the treated sample, and corresponding direct effects that are relevant for decision-based outcomes. We provide weighting and g-computation estimators in the presence of study attrition and sketch a simulation-based procedure for sample size determinations based on precision (e.g., confidence interval width). We validate our proposed methods through a brief simulation study and apply our approach to evaluate the RICH LIFE intervention, a multilevel healthcare intervention designed to reduce racial and ethnic disparities in hypertension control.

Abstract
BACKGROUND Personal characteristics may be associated with believing misinformation and not believing in best practices to protect oneself from COVID-19. OBJECTIVE To examine the associations of a person's age, race/ethnicity, education, residence, health literacy, medical mistrust level, and sources of health-related information with their COVID-19 health and conspiracy myth beliefs. DESIGN We surveyed adults with hypertension in Maryland and Pennsylvania between August 2020 and March 2021. Incorrect responses were summed for eight health (mean = 0.68; range 0-5) and two conspiracy (mean = 0.92; range 0-2) COVID-19 questions. Higher scores indicated more incorrect responses. Statistical analyses included two-sample t-tests, Spearman's correlation, and log binomial regression. PARTICIPANTS In total, 561 primary care patients (mean age = 62.3 years, 60.2% female, 46.0% Black, 10.2% Hispanic, 28.2% with a Bachelor's degree or higher, 42.8% with annual household income less than $60,000) with a diagnosis of hypertension and at least one of five commonly associated conditions. MAIN MEASURES Sociodemographic characteristics, health literacy, medical mistrust level, source of health-related information, and COVID-19 conspiracy and health myth beliefs. KEY RESULTS In multivariable analyses, participants who did not get information from medical professional sources (prevalence ratio (PR) = 1.28; 95% CI = 1.06-1.55), had less than a bachelor's degree (PR = 1.49; 95% CI = 1.12-1.99), were less confident filling out medical forms (PR = 1.24; 95% CI = 1.02-1.50), and had higher medical mistrust (PR = 1.34; 95% CI = 1.05-1.69) were more likely to believe any health myths. Participants who had less than a bachelor's degree (PR = 1.22; 95% CI = 1.02-1.45), were less confident filling out medical forms (PR = 1.21; 95% CI = 1.09-1.34), and had higher medical mistrust (PR = 1.72; 95% CI = 1.43-2.06) were more likely to believe any conspiracy myths. CONCLUSIONS Lower educational attainment and health literacy, greater medical mistrust, and certain sources of health information are associated with misinformed COVID-19 beliefs. Programs addressing misinformation should focus on groups affected by these social determinants of health by encouraging reliance on scientific sources.

Abstract
Introduction The COVID-19 pandemic exacerbated mental health concerns and stress among American Indians and Alaska Natives (AI/ANs) in the United States, as well as among frontline workers responding to the pandemic. Psychological First Aid (PFA) is a promising intervention to support mental wellbeing and coping skills during and after traumatic events, such as the COVID-19 pandemic. Since PFA is often implemented rapidly in the wake of a disaster or traumatic event, evidence evaluating its impact is lacking. This paper reports pilot evaluation results from a culturally adapted PFA training designed to support COVID-19 frontline workers and the AI/AN communities they serve during the pandemic. Methods This study was designed and implemented in partnership with a collaborative work group of public health experts and frontline workers in AI/AN communities. We conducted a pre-post, online pilot evaluation of a culturally adapted online PFA training with COVID-19 frontline workers serving AI/AN communities. Participants completed a baseline survey and two follow-up surveys 1 week and 3 months after completing the PFA training. Surveys included demographic questions and measures of anxiety, burnout, stress, positive mental health, communal mastery, coping skills, PFA knowledge, confidence in PFA skills, and satisfaction with the PFA training. Results Participants included N = 56 COVID-19 frontline workers in AI/AN communities, 75% were AI/AN, 87% were female, and most (82%) were between the ages of 30-59. Participants reported high satisfaction with the training and knowledge of PFA skills. Pilot results showed significant increases in positive mental health and social wellbeing and reductions in burnout from baseline to 3 months after completing the PFA training among frontline workers. There were no changes in communal mastery, coping skills, stress, or anxiety symptoms during the study period. Discussion To our knowledge, this is the first pilot evaluation of a PFA training designed and culturally adapted with and for AI/AN communities. Given that many AI/AN communities were disproportionately impacted by COVID-19 and prior mental health inequities, addressing acute and chronic stress is of crucial importance. Addressing traumatic stress through culturally adapted interventions, including Indigenous PFA, is crucial to advancing holistic wellbeing for AI/AN communities.

Abstract
Purpose: To examine disparities in visual acuity (VA) outcomes 1 year and 2 years after initiation of diabetic retinopathy (DR) or diabetic macular edema (DME) treatment in patients based on race/ethnicity and insurance status, accounting for disease severity. Methods: This retrospective analysis used the IRIS Registry and included DR patients older than 18 years with documented antivascular endothelial growth factor (anti-VEGF) treatment and VA data for at least 2 years. International Classification of Diseases, Tenth Revision, Clinical Modification codes were used to determine the severity of DR and DME presence. VA outcomes were assessed using multivariable linear regressions and anti-VEGF drug use by multivariable logistic regressions, with race and insurance status as independent variables. Main outcome measures comprised the mean VA change at 1 year and 2 years and percentage of patients treated with bevacizumab. Results: The study included 43 274 eyes. White patients presented with a higher mean VA and lower mean DR severity than Black patients and Hispanic patients. Multivariable logistic regression showed Hispanic patients were significantly more likely to be treated with bevacizumab than White patients across all insurance types, controlling for disease severity and VA. After 1 year, the letter improvement was 1.73, 1.33, and 1.13 in White patients, Black patients, and Hispanic patients, respectively. Multivariable linear regression suggested that across races, Medicaid-insured patients had significantly smaller gains in VA than privately insured patients. Conclusions: Race-based and insurance-based differences in 1-year and 2-year outcomes after anti-VEGF treatment for DR and anti-VEGF treatment patterns suggest a need to ensure earlier and more effective treatment of minority and underserved patients in the United States.

Abstract
OBJECTIVE To explore the association of neighborhood-level socioeconomic status (SES) and race with developing pelvic inflammatory disease (PID) after sexually transmitted infection (STI) among female adolescents and young adults in Maryland. METHODS We used Maryland statewide hospital claims data (outpatient and inpatient visits) for this retrospective cohort study. Female adolescents and young adults aged 15-24 years who had at least one STI from July 1, 2013, to March 31, 2015, were included. A participant entered the cohort on the date of the first STI diagnosis and was followed up until PID occurrence or 3 years after the first STI. Median household income of the participant's residential ZIP code tabulation area was used as the neighborhood-level SES. Discrete-time hazard models were used to estimate the hazard of PID. RESULTS Of the 2,873 participants, 88.5% were of Black race, and 67.2% were aged 20-24 years. The hazard of PID after an STI among Black women was 1.40 times that of White women (95% CI 1.06-1.85). After adjustment for age, insurance type, and number of STI events, the hazard ratio (HR) did not change. However, adding neighborhood-level SES to the model attenuated the disparity in PID after STI between Black and White women (HR 1.25, 95% CI 0.94-1.67). CONCLUSION Racial disparities in PID diagnosis are mitigated by neighborhood-level SES.

Abstract
INTRODUCTION AND HYPOTHESIS Educational interventions have been effective in improving postpartum knowledge, performance of pelvic floor exercises, and bowel-specific quality-of-life. Our primary objective was to determine if a video-based educational intervention on pelvic floor disorders (PFDs) would increase Spanish-speaking women's knowledge of PFDs, and secondarily to assess if it would decrease pelvic floor symptoms. We hypothesized that Spanish-speaking women would improve their pelvic floor knowledge and symptoms post-intervention. METHODS Inclusion criteria included women age 18 years and older and self-reported as a predominantly Spanish-speaker or equally bilingual English- and Spanish-speaker. Changes in knowledge were assessed with the Prolapse and Incontinence Knowledge Questionnaire (PIKQ). Changes in symptoms were assessed with the Pelvic Floor Distress Inventory-20 (PFDI-20). Linear regression assessed for independent effects. RESULTS One hundred and fourteen women were enrolled and 112 completed the pre- and post-intervention PIKQ. Mean (standard deviation [SD]) age was 50 (14) years. Immediate post-intervention scores showed significant improvement in knowledge. Total PIKQ score improved by 5.1 (4.7) points (p < 0.001). POP subscore improved by 2.7 (2.7) points (p<0.001) and UI subscore improved by 2.3 (2.5) points (p < 0.001). Improvement in knowledge continued after four weeks (p < 0.001). PFDI-20 prolapse (p=0.02), colorectal-anal (p < 0.001) and urinary (p = 0.01) scores significantly improved only for the most symptomatic women at baseline. Using linear regression, total PIKQ (p = 0.03) and total PFDI-20 scores (p = 0.04) were associated with predominantly Spanish-speakers versus fully bilingual. CONCLUSION Findings support the efficacy of a video-based educational intervention to improve knowledge of PFDs in Spanish-speaking women. The most symptomatic women benefitted from this intervention.

Abstract
ABSTRACT This mixed-methods study aims to understand what the perceptions of leaders and healthcare professionals are regarding causes of disparities, cultural competence, and motivation before launching a disparity reduction project in hypertension care, contrasting perceptions in Federally Qualified Health Centers (FQHCs), and in a non-FQHC system. We interviewed leaders of six participating primary care systems and surveyed providers and staff. FQHC respondents reported more positive cultural competence attitudes and behavior, higher motivation to implement the project, and less concern about barriers to caring for disadvantaged patients than those in the non-FQHC practices; however, egalitarian beliefs were similar among all. Qualitative analysis suggested that the organizational missions of the FQHCs reflect their critical role in serving vulnerable populations. All system leaders were aware of the challenges of provider care to underserved groups, but comprehensive initiatives to address social determinants of health and improve cultural competence were still needed in both system types. The study provides insights into the perceptions and motivations of primary care organizational leaders and providers who are interested in improving chronic care. It also offers an example for care disparity programs to understand commitment and values of the participants for tailoring interventions and setting baseline for progress.

Abstract
BACKGROUND Disparities in hypertension outcomes persist among Black and Hispanic adults and persons living in poverty in the United States. The "LINKED-BP Program" is a multi-level intervention linking home blood pressure (BP) monitoring with a mobile health application, support from community health workers (CHWs), and BP measurement training at primary care practices to improve BP. This study is part of the American Heart Association RESTORE (AddREssing Social Determinants TO pRevent hypErtension) Network. This study aims to examine the effect of the LINKED-BP Program on BP reduction and to evaluate the reach, adoption, sustainability, and cost-effectiveness of the intervention. METHODS Using a hybrid type I effectiveness-implementation design, 600 adults who have elevated BP or untreated stage 1 hypertension without diabetes, chronic kidney disease, history of cardiovascular disease (stroke or coronary heart disease) and age < 65 years will be recruited from 20 primary care practices including community health centers in the Maryland area. The practices are randomly assigned to the intervention or the enhanced usual care arms. Patients in the LINKED-BP Program receive training on home BP monitoring, BP telemonitoring through the Sphygmo app, and CHW telehealth visits for education and counseling on lifestyle modification over 12 months. The primary clinical outcome is change from baseline in systolic BP at 6 and 12 months. DISCUSSIONS The LINKED-BP Program tests a sustainable, scalable approach to prevent hypertension and advance health equity. The findings will inform implementation strategies that address social determinants of health and barriers to hypertension prevention in underserved populations.

Abstract
BACKGROUND Identifying potential pathways through which adverse childhood experiences (ACEs) impact health and health behavior remains important, given ACE survivors' increased risk for cardiovascular disease and poor cardiovascular health behaviors. This study examines whether modifiable variables-depression and patient activation-explain the relationship between ACEs and medication adherence. METHODS Using baseline data from a pragmatic trial designed to decrease disparities in hypertension control, we conducted regression analyses to examine whether depression and patient activation mediated the association between ACEs and medication adherence. Data were collected between August 2017 and October 2019 (n = 1,818). RESULTS Participants were predominantly female (59.4%) and Black or African American (57%) with uncontrolled blood pressure (mean-152.3/85.5 mm Hg). Most participants reported experiencing at least 1 ACE (71%) and approximately 50% reported being adherent to their blood pressure medication. A significant indirect effect between ACEs and medication adherence was found for depression symptoms (Sobel's test z = -5.46, P < 0.001). Patient activation was not a mediator in these relationships. CONCLUSIONS Experiencing more depression symptoms significantly accounted for the association between ACEs and medication adherence in a diverse sample of adults with uncontrolled blood pressure. Addressing depression symptoms, which may result from experiences with ACEs and other current stressors, could translate to better medication adherence and, potentially, better blood pressure control among this high-risk group. Given the serious lifetime health implications of ACEs, continued efforts are needed for primary prevention of childhood adversities.

Abstract
BACKGROUND Dry, itchy skin can lower quality of life (QoL) and aggravate skin diseases. Moisturizing skin care products can have beneficial effects on dry skin. However, the role of a daily skin care routine is understudied. OBJECTIVE To understand how daily skin care with a mild cleanser and moisturizer impacts skin health and patients' QoL, in dry skin population. METHODS A randomized, investigator-blinded study of 52 participants with moderate to severe dry skin. The treatment group (n = 39) used mild cleanser and moisturizer twice daily for two weeks whereas the control group (n = 13) used mild cleanser without moisturizer. Total Clinical Score (TCS; erythema, scale and fissures), Visual Dryness Score (VDS) and subjective itch-related quality of life (ItchyQoL) were collected. RESULTS The treatment group showed significantly more improvement in TCS and VDS compared to the control group after two weeks. Among the three components of the ItchyQoL (symptoms, functioning, and emotions), symptom showed significantly greater improvement in the treatment compared to the control group. Over 80% of participants in the treatment group agreed that the regimen led to decrease in dryness/pruritus and improved skin texture. CONCLUSIONS A consistent skin care regimen should be an integral component of management of dry skin.

Abstract
BACKGROUND Mycoplasma genitalium (MG) is a prevalent sexually transmitted infection, but little is known about the associated inflammatory signatures in the genital tract of adolescents and young adult women. METHODS Adolescents and young adult women aged 13 to 24 years were recruited. Demographic information, sexual behavior history, and medical history were collected. Vaginal swab samples were tested for MG, Chlamydia trachomatis, Neisseria gonorrhoeae, Trichomonas vaginalis, bacterial vaginosis, and measurement of 13 cytokines, chemokines, and antimicrobial proteins. Vaginal cytokine concentrations were compared by MG infection status. The strength of associations between multiple factors and MG infection was evaluated. RESULTS Of 215 participants, 16.7% (95% confidence interval [CI], 12.0%-22.4%) had MG infection. Inflammation was not associated with MG infection (P > 0.05). M. genitalium infection was associated with C. trachomatis infection (adjusted prevalence ratio [aPrR], 3.02; 95% CI, 1.69-5.39), bisexual behavior in the past 3 months (aPrR, 2.07; 95% CI, 1.18-3.64), genitourinary symptoms (aPrR, 2.06; 95% CI, 1.22-3.49), and self-reported Black race (aPrR, 3.53; 95% CI, 1.11-11.18). CONCLUSIONS Higher levels of genital tract cytokines were not associated with MG infection. C. trachomatis infection, bisexual behavior, self-reported Black race, and genitourinary symptoms were associated with an increased likelihood of MG infection.

Abstract
INTRODUCTION Sudden cardiac death is the main cause of death among firefighters. The goal of this study is to identify firefighters at risk for cardiovascular disease using coronary artery calcium screening. METHODS Asymptomatic firefighters aged ≥40 years without known cardiovascular disease or diabetes (N=487) were recruited from fire departments in 3 Maryland counties from 2016 to 2018, with data analysis from 2018 to 2019. The cardiovascular disease prevention program included an evaluation of blood pressure, cholesterol, BMI, fasting glucose, medications, and a coronary calcium scan. A subset (n=100) was evaluated in more detail, including family history, metabolic syndrome, diet, exercise, smoking, and atherosclerotic cardiovascular disease risk score. RESULTS Results indicated that 191 (39%) firefighters had a coronary artery calcium score >0, of which 91% were above the average for age, sex, and ethnicity. On univariable logistic regression, older age, male sex, hypertension, BMI, and glucose were significantly (p<0.05) associated with a higher likelihood of having any coronary artery calcium. Multiple logistic regression found that older age; male sex; taking lipid-lowering or antihypertensive medications; and higher low-density lipoprotein cholesterol, BMI, and fasting blood glucose were significantly associated with a higher likelihood of having coronary artery calcium. Of those with coronary artery calcium, 141 (74%) were not on lipid-lowering medication. In addition, 47 (94%) of those on lipid-lowering medication had a low-density lipoprotein cholesterol >70 mg/dL. In the detailed subset, 30 (30%) had coronary artery calcium. Among these, 28 (93%) had an atherosclerotic cardiovascular disease risk score <7.5%. Thus, if atherosclerotic cardiovascular disease scores alone were used to assess risk in this subset, an opportunity would have been missed to identify and treat firefighters who may have benefited from more aggressive treatment. CONCLUSIONS A coronary artery calcium scan may identify the firefighters at increased risk for cardiovascular disease. A comprehensive cardiovascular disease prevention program implemented early in a firefighter's career may help reduce cardiovascular disease risk and thus death and disability in this high-risk population.

Abstract
Background Our objective was to determine if the addition of ultraviolet-C (UV-C) light to daily and discharge patient room cleaning reduces healthcare-associated infection rates of vancomycin-resistant enterococci (VRE) and Clostridioides difficile in immunocompromised adults. Methods We performed a cluster randomized crossover control trial in 4 cancer and 1 solid organ transplant in-patient units at the Johns Hopkins Hospital, Baltimore, Maryland. For study year 1, each unit was randomized to intervention of UV-C light plus standard environmental cleaning or control of standard environmental cleaning, followed by a 5-week washout period. In study year 2, units switched assignments. The outcomes were healthcare-associated rates of VRE or C. difficile. Statistical inference used a two-stage approach recommended for cluster-randomized trials with <15 clusters/arm. Results In total, 302 new VRE infections were observed during 45787 at risk patient-days. The incidence in control and intervention groups was 6.68 and 6.52 per 1000 patient-days respectively; the unadjusted incidence rate ratio (IRR) was 0.98 (95% confidence interval [CI], .78 − 1.22; P = .54). There were 84 new C. difficile infections observed during 26118 at risk patient-days. The incidence in control and intervention periods was 2.64 and 3.78 per 1000 patient-days respectively; the unadjusted IRR was 1.43 (95% CI, .93 − 2.21; P = .98). Conclusions When used daily and at post discharge in addition to standard environmental cleaning, UV-C disinfection did not reduce VRE or C. difficile infection rates in cancer and solid organ transplant units.

Abstract
BACKGROUND Polycyclic aromatic hydrocarbons (PAHs) are generated during the incomplete combustion of coal/oil/gas and waste. The role of PAH exposure in the atopic triad remains poorly understood. Due to their lipophilic nature, PAHs deposit in adipocytes, potentially placing elderly and those who are overweight at higher risk. OBJECTIVE To investigate the association between urinary PAHs and symptoms of atopic triad (chronic pruritus, sneezing, and wheezing). METHODS Binary multivariable logistic regression was performed to estimate the association of nine urinary PAHs and atopic diseases followed by subgroup analyses by age (children 6-17, adults 18-49, elderly ≥50 years) and body mass index (BMI) (normal: BMI <25, overweight: BMI ≥ 25 kg/m2) among 2,242 participants of National Health and Nutrition Examination Survey 2005-2006 dataset. RESULTS 1-hydroxynaphthalene (1-NAP) and hydroxyfluorenes (FLUs) were positively associated with wheezing. When stratified by age, positive associations were found between 1-NAP with wheezing in children/adults and 2-/3-FLU with wheezing in adults/elderly. 3-hydroxyphenanthrene (3-PHE) and 1-hydroxypyrene were positively associated with chronic pruritus in elderly. When stratified by BMI, positive associations were found between 2-PHE with chronic pruritus, 1-NAP and FLUs with wheezing in overweight. CONCLUSION Urinary PAH levels were positively associated with atopic triad and this connection was influenced by age and BMI.

[PMID: 33610104 DOI: 10.1016/j.yebeh.2021.107807] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/18/2020] [Revised: 01/16/2021] [Accepted: 01/16/2021] [Indexed: 10/22/2022]
Abstract
OBJECTIVES Patients with epilepsy are known to exhibit high rates of comorbid psychiatric disorders such as depression, anxiety, and other mood disorders. Little is known about the psychiatric effects of a ketogenic diet therapy (KDT) on adults with epilepsy. The objective of this study was to better understand the relationship between KDT and psychological state based on depressive and anxiety symptoms in adults with chronic epilepsy. METHODS Adults at the Johns Hopkins Adult Epilepsy Diet Center on a modified Atkins diet (MAD) for at least one month were surveyed retrospectively. Adults who were diet naïve were given a baseline survey and an additional survey after 3 months or more on MAD. Surveys included validated measures of depressive and anxiety symptoms as well as their severity. Participant demographics, seizure frequency, and use of concomitant antiseizure drugs (ASDs), chronic anxiolytics (excluding as-needed benzodiazepines for seizure rescue only), and/or antidepressant drugs were extracted from electronic medical records. RESULTS One-hundred participants aged 19-75 enrolled in the study. Sixty participants filled out a single retrospective survey. Of 40 diet naïve participants who filled out a baseline prospective survey, 19 completed a follow-up survey while on MAD and 21 participants were lost to follow-up. Longer diet duration was significantly associated with fewer anxiety and depressive symptoms, based on psychiatric measure scores, in retrospective study participants. Lower seizure frequency was also significantly associated with less anxiety symptoms in the retrospective cohort. Prospective study participants did not experience significant change in anxiety or depressive symptoms on the diet. There was a significant correlation between higher ketone level and responder rate (≥50% seizure reduction) in the prospective cohort, although no correlation between ketone level and change in psychiatric symptoms was seen. SIGNIFICANCE Psychiatric comorbidity among patients with epilepsy is quite common and can be influenced by multiple factors such as seizure frequency, the use of various ASDs, social factors, and underlying etiology. Although ketogenic diet therapies have been in clinical use for one century, the psychiatric impacts have been insufficiently explored. This study provides preliminary evidence that KDT may have a positive impact on psychological state independent of seizure reduction or ketone body production and may be influenced by longer duration of diet therapy. These results support further investigation into specific effects and potential therapeutic benefits on various psychiatric disorders.

Abstract
BACKGROUND Phenols and parabens (P&Ps) are commonly found in skin care products. However, P&Ps' role in pruritus and eczema has not been studied. OBJECTIVE The aim of the study was to investigate the association between P&Ps, and pruritus and eczema. METHODS This is a cross-sectional population-based study of 2202 participants. We examined the association between urinary phenols (triclosan, bisphenol A, benzophenone-3) and parabens (methyl and propyl parabens) and itchy rash/eczema using the 2005-2006 National Health and Nutrition Examination Survey database. Phenols and parabens were divided into quartiles (Qs) with the first Q as the reference. We calculated odds ratios and 95% confidence intervals, adjusting for multiple variables. RESULTS Urinary triclosan was inversely associated with itchy rash (P trend = 0.048). In a subpopulation analysis by race/ethnicity, urinary methyl paraben was positively associated with itchy rash in African Americans (fourth Q vs first Q: odds ratio, 12.60; 95% confidence interval, 1.03-154.06; P trend = 0.02). Triclosan was inversely associated with eczema in whites (P trend = 0.04). CONCLUSIONS Methyl paraben exposure may increase the risk of itchy rash in African Americans, whereas triclosan may decrease the risk of itchy rash and eczema. The potential effect of triclosan and methyl paraben in pruritus and eczema warrants further study.

Nutrients 2021; 13:nu13020538.

Abstract
The Dietary Approaches to Stop Hypertension (DASH) diet reduces serum urate (SU); however, the impact of the DASH diet has not been previously evaluated among patients with gout. We conducted a randomized, controlled, crossover pilot study to test the effects of ~$105/week ($15/day) of dietitian-directed groceries (DDG), patterned after the DASH diet, on SU, compared with self-directed grocery shopping (SDG). Participants had gout and were not taking urate lowering therapy. Each intervention period lasted 4 weeks; crossover occurred without a washout period. The primary endpoint was SU. Compliance was assessed by end-of-period fasting spot urine potassium and sodium measurements and self-reported consumption of daily servings of fruit and vegetables. We randomized 43 participants (19% women, 49% black, mean age 59 years) with 100% follow-up. Mean baseline SU was 8.1 mg/dL (SD, 0.8). During Period 1, DDG lowered SU by 0.55 mg/dL (95% CI: 0.07, 1.04) compared to SDG by 0.0 mg/dL (95% CI: −0.44, 0.44). However, after crossover (Period 2), the SU difference between groups was the opposite: SDG reduced SU by −0.48 mg/dL (95% CI: −0.98, 0.01) compared to DDG by −0.05 mg/dL (95% CI: −0.48, 0.38; P for interaction by period = 0.11). Nevertheless, DDG improved self-reported intake of fruit and vegetables (3.1 servings/day; 95% CI: 1.5, 4.8) and significantly reduced total spot urine sodium excretion by 22 percentage points (95% CI: −34.0, −8.6). Though relatively small in scale, this pilot study suggests that dietitian-directed, DASH-patterned groceries may lower SU among gout patients not on urate-lowering drugs. However, behavior intervention crossover trials without a washout period are likely vulnerable to strong carryover effects. Definitive evaluation of the DASH diet as a treatment for gout will require a controlled feeding trial, ideally with a parallel-design.

Abstract
Objectives The use of collaborative care teams, comprising nurse care managers and community health workers, has emerged as a promising strategy to tackle hypertension disparities by addressing patients' social determinants of health. We sought to identify which social determinants of health are associated with a patient's likelihood of engaging with collaborative care team members and with the nurse care manager's likelihood of enlisting community health workers (CHW) to provide additional support to patients. Methods We conducted a within-group longitudinal analysis of patients assigned to receive a collaborative care intervention in a pragmatic, cluster randomized trial that aims to reduce disparities in hypertension control (N=888). Generalized estimating equations were used to identify which social determinants of health, reported on the study's baseline survey, were associated with the odds of patients engaging with the collaborative care intervention, and of nurses deploying community health workers. Results Patients who were unable to work and those with higher health literacy were less likely to engage with the collaborative care team than those who were employed full time or had lower health literacy, respectively. Patients had a greater likelihood of being referred to a community health worker by their care manager if they reported higher health literacy, perceived stress, or food insecurity, while those reporting higher numeracy had lower odds of receiving a CHW referral. Implications/Conclusions A patient's social determinants of health influence the extent of engagement in a collaborative care intervention and nurse care manager appraisals of the need for supplementary support provided by community health workers.

Abstract
Background Uncontrolled hypertension is a significant risk factor for cardiovascular morbidity and mortality. In the United States, many patients remain uncontrolled, in part, due to poor medication adherence. Efforts to improve hypertension control include not only attending to medical management of the disease but also the social determinants of health, which impact medication adherence, and ultimately blood pressure control. Purpose To determine which social determinants - health care access or community and social stressors - explain medication adherence. Methods In this cross-sectional analysis, we used baseline data (N=1820, collected August 2017 to October 2019) from a pragmatic trial, which compares the effectiveness of a multi-level intervention including collaborative care and a stepped approach with enhanced standard of care for improving blood pressure. We used logistic regression analyses to examine the association between patient experiences of care and community and social stressors with medication adherence. Results The participants represented a diverse sample: mean age of 60 years; 59% female; 57.3% Black, 9.6% Hispanic, and 33.2% White. All participants had a blood pressure reading ≥140/90 mm Hg (mean blood pressure - 152/85 mm Hg). Half of the participants reported some level of non-adherence to medication. Regression analysis showed that, compared with Whites, Blacks (AOR .47; 95% CIs: .37-.60, P<.001) and Hispanics (AOR .48; 95% CIs: .32- .73, P<.001) were less likely to report medication adherence. Also part-time workers (AOR .57; 95% CIs: .38-.86, P<.05), and those who reported greater perceived stress (AOR .94; 95% CIs: .91 - .98, P<.001) and everyday discrimination (AOR .73; 95% CIs: .59 - .89; P<.001) had lower odds of medication adherence. Among Blacks, greater perceived stress (AOR .93; 95% CIs: .88-.98, P<.001) and everyday discrimination (AOR .63; 95% CIs: .49 - .82, P<.005) were negatively associated with medication adherence. Among Hispanics, greater report of everyday discrimination (AOR .36; 95% CIs: .14 - .89, P<.005) was associated with lower odds of medication adherence. Among Whites, the negative effect of perceived stress on medication adherence was attenuated by emotional support. Conclusions Using the social determinants of health framework, we identified associations between stress, everyday discrimination and medication adherence among non-Hispanic Blacks and Hispanics that were independent of health status and other social determinants. Programs to enhance self-management for African American and Hispanic patients with uncontrolled blood pressure should include a specific focus on addressing social stressors.

Abstract
OBJECTIVES (a) To quantify changes in mucociliary clearance (MCC) over time in children with cystic fibrosis (CF) and the relationship between MCC and rate of infection with Pseudomonas aeruginosa (PA); (b) to determine the impact of MCC on the evolution of CF lung disease; and (c) to explore the role of mucus composition as a determinant of MCC. METHODS Children with CF, who had previously undergone an MCC measurement (visit 1), underwent the following tests 3 to 10 years later: (a) second MCC measurement (visit 2); (b) multiple breath washout to assess ventilation inhomogeneity, expressed as lung clearance index (LCI); (c) high resolution computed tomography lung scan (HRCT); and (d) induced sputum test. Number of PA + cultures/year between visits was documented and mucus dry weight was quantified in the children and adult controls. RESULTS Nineteen children completed both visits. Median time between visits was 4.6 years. Clearance declined 30% between visits. Lower MCC on visit 2 was associated with more PA+ cultures/year between visits. Lower MCC values on visit 1 were associated with higher LCI values and higher HRCT scores on visit 2. Mucus dry weight was significantly higher in children with CF compared with controls. Higher dry weights were associated with lower MCC. CONCLUSIONS Mucociliary clearance declines significantly over time in children with CF. The decline is associated with PA infection rate and is affected by mucus composition. Children with early slowing of MCC appear to be at risk for developing ventilation inhomogeneity and parenchymal lung damage when they are older.

Abstract
BACKGROUND Sudden cardiac arrest is the most common cause of death worldwide, and prognostication after survival remains challenging. Decisions regarding prognosis can be fraught with error in the immediate postarrest period, with guidelines recommending the use of various tests, including blood gas pH, to determine which interventions to perform. Despite these recommendations, the prognostic utility of blood gas pH remains unclear. OBJECTIVES In this retrospective cohort study, we aimed to demonstrate the prognostic utility of emergency department blood gas pH after return of spontaneous circulation (ROSC) in out-of-hospital cardiac arrest. METHODS A retrospective cohort study was performed, including all adult survivors of out-of-hospital cardiac arrest (n = 79). Primary disease-oriented outcome was venous blood pH after ROSC and survival to hospital discharge. RESULTS In patients with out-of-hospital cardiac arrest, pH < 7.2 was associated with decreased likelihood of survival to hospital discharge (odds ratio 0.06), with every 0.1-unit increase in pH being associated with an increased likelihood of survival (1.98). Based on the area under the receiver curve, the pH that optimizes sensitivity and specificity for predicting survival was 7.04. CONCLUSION Both presence and degree of acidemia on initial blood gas after ROSC was associated with a decreased likelihood of survival to hospital discharge. The optimal cutoff for prediction in this cohort of patients was 7.04. Using a higher pH cutoff would result in fewer patients receiving intervention that would otherwise have survived.
