RESUMO

BACKGROUND: Epidemiological support for prophylactic treatment of left ventricular dysfunction (LVD) in Duchenne muscular dystrophy is limited. We used retrospective, population-based surveillance data from the Muscular Dystrophy Surveillance, Tracking and Research Network to evaluate whether prophylaxis delays LVD onset. METHODS: We analyzed 455 males born during 1982-2009. Age at first abnormal echocardiogram (ejection fraction <55% or shortening fraction <28%) determined LVD onset. Prophylaxis was defined as cardiac medication use at least 1 year prior to LVD. Corticosteroid use was also coded. Kaplan-Meier curve estimation and Cox Proportional Hazard modeling with time-varying covariates describe associations. RESULTS: LVD was identified among 40.7%; average onset age was 14.2 years. Prophylaxis was identified for 20.2% and corticosteroids for 57.4%. Prophylaxis showed delayed LVD onset (p < .001) and lower hazard of dysfunction (adjusted hazard ratio [aHR] = 0.39, 95%CL = 0.22, 0.65) compared to untreated. Compared to no treatment, continuous corticosteroids only (aHR = 1.01, 95%CL = 0.66, 1.53) and prophylaxis only (aHR = 0.67, 95%CL = 0.25, 1.50) were not cardioprotective, but prophylaxis plus continuous corticosteroids were associated with lower hazard of dysfunction (aHR = 0.37, 95%CL = 0.15, 0.80). CONCLUSIONS: Proactive cardiac treatment and monitoring are critical aspects of managing Duchenne muscular dystrophy. Consistent with clinical care guidelines, this study supports clinical benefit from cardiac medications initiated prior to documented LVD and suggests further benefit when combined with corticosteroids.

RESUMO

BACKGROUND: The widespread adoption of the electronic health record (EHR) has resulted in vast repositories of EHR big data that are being used to identify patterns and correlations that translate into data-informed health care decision making. PROBLEM: Health care professionals need the skills necessary to navigate a digitized, data-rich health care environment as big data plays an increasingly integral role in health care. APPROACH: Faculty incorporated the concept of big data in an asynchronous online course allowing an interprofessional mix of students to analyze EHR big data on over a million patients. OUTCOMES: Students conducted a descriptive analysis of cohorts of patients with selected diagnoses and presented their findings. CONCLUSIONS: Students collaborated with an interprofessional team to analyze EHR big data on selected variables. The teams used data visualization tools to describe an assigned diagnosis patient population.

RESUMO

INTRODUCTION: Racial/ethnic differences in diagnostic and treatment services have been identified for a range of health conditions and outcomes. The current study aimed to analyze whether there are racial/ethnic differences in the timing of diagnostic testing and treatments for males with Duchenne muscular dystrophy (DMD). METHODS: Diagnostic and clinical data for male individuals with DMD born during 1990-2010 were analyzed from eight sites (Arizona, Colorado, Georgia, Iowa, Piedmont Region of North Carolina, Western New York, South Carolina, and Utah) of the Muscular Dystrophy Surveillance, Tracking, and Research Network (MD STARnet). Seven milestones related to diagnosis/treatment experiences were selected as outcomes. Times to each milestone were estimated and compared by four racial/ethnic groups using Kaplan-Meier estimation and Cox proportional-hazards models. Times between initial evaluation or diagnostic testing and later milestones were also compared by race/ethnicity. RESULTS: We identified 682 males with definite or probable DMD of whom 61.7% were non-Hispanic white, 20.5% Hispanic, 10.6% other, and 7.2% non-Hispanic black. Seven milestone events were studied (initial evaluation, first neurology/neuromuscular visit, diagnosis, corticosteroid treatment first offered, corticosteroid treatment started, first electrocardiogram or echocardiogram, and first pulmonary function test). The first five milestone events occurred at an older age for non-Hispanic black individuals compared to non-Hispanic white individuals. Time to first offering of corticosteroids and initiation of corticosteroid therapy was later for Hispanic individuals compared to non-Hispanic white individuals. When accounting for timing of initial evaluation/diagnosis, offering of corticosteroids continued to occur later, but first pulmonary testing occurred earlier, among Hispanic individuals compared to non-Hispanic whites. No significant delays remained for non-Hispanic black individuals after accounting for later initial evaluation/diagnosis. CONCLUSION: We described racial/ethnic differences in ages at selected diagnostic and treatment milestones. The most notable differences were significant delays for five of seven milestones in non-Hispanic black individuals, which appeared to be attributable to later initial evaluation/diagnosis. Findings for Hispanic individuals were less consistent. Efforts to address barriers to early evaluation and diagnosis for non-Hispanic black children with DMD may promote more timely initiation of recommended disease monitoring and interventions.

RESUMO

INTRODUCTION/AIMS: With current and anticipated disease-modifying treatments, including gene therapy, an early diagnosis for Duchenne muscular dystrophy (DMD) is crucial to assure maximum benefit. In 2009, a study from the Muscular Dystrophy Surveillance, Tracking, and Research Network (MD STARnet) showed an average diagnosis age of 5 years among males with DMD born from January 1, 1982 to December 31, 2000. Initiatives were implemented by the US Centers for Disease Control and Prevention (CDC) and patient organizations to reduce time to diagnosis. We conducted a follow-up study in a surveillance cohort born after January 1, 2000 to determine whether there has been an improvement in time to diagnosis. METHODS: We assessed the age of diagnosis among males with DMD born from January 1, 2000 to December 31, 2015 using data collected by six US MD STARnet surveillance sites (Colorado, Iowa, western New York State, the Piedmont region of North Carolina, South Carolina, and Utah). The analytic cohort included 221 males with definite or probable DMD diagnosis without a documented family history. We computed frequency count and percentage for categorical variables, and mean, median, and standard deviation (SD) for continuous variables. RESULTS: The mean [median] ages in years of diagnostic milestones were: first signs, 2.7 [2.0]; first creatine kinase (CK), 4.6 [4.6]; DNA/muscle biopsy testing, 4.9 [4.8]; and time from first signs to diagnostic confirmation, 2.2 [1.4]. DISCUSSION: The time interval between first signs of DMD and diagnosis remains unchanged at 2.2 years. This results in lost opportunities for timely genetic counseling, implementation of standards of care, initiation of glucocorticoids, and participation in clinical trials.

RESUMO

In this retrospective cohort study, we characterize the health profile of preterm males with Duchenne muscular dystrophy. Major clinical milestones (ambulation cessation, assisted ventilation use, and onset of left ventricular dysfunction) and corticosteroids use in males with Duchenne muscular dystrophy identified through a population-based surveillance system were analyzed using Kaplan-Meier survival curves and Cox proportional hazards modeling. The adjusted risk of receiving any respiratory intervention among preterm males with Duchenne muscular dystrophy was 87% higher than among the corresponding full-term males with Duchenne muscular dystrophy. The adjusted risks for ambulation cessation and left ventricular dysfunction were modestly elevated among preterm compared to full-term males, but the 95% confidence intervals contained the null. No difference in the start of corticosteroid use between preterm and full-term Duchenne muscular dystrophy males was observed. Overall, the disease course seems to be similar between preterm and full-term males with Duchenne muscular dystrophy; however, pulmonary function seems to be affected earlier among preterm males with Duchenne muscular dystrophy.

RESUMO

Mississippi ranks as the nation's least-healthy state. There is a shortage of trained preventive medicine (PM) physicians in the state. The Department of Preventive Medicine at The University of Mississippi Medical Center was reinstated in 2015 to address this need. Initial PM residency accreditation was awarded in November of 2017 with subsequent notification of 10-year accreditation status in April of 2020 allowing up to 4 PGY-2 and 4 PGY-3 resident positions per year. The residency experiences provided by the program are varied and unique due to the program being housed in both the School of Medicine and the School of Population Health. Preventive medicine residents have the opportunity to complete the American College of Lifestyle Medicine's Lifestyle Medicine Residency Curriculum. Through our diverse didactic and clinical experiences, we are optimistic that our program will continue to attract, train, and retain PM physicians for our state.

RESUMO

Context: Stress, anxiety, and depression affect medical student populations at rates disproportionate to those of general student populations. Emotional intelligence (EI) has been suggested as a protective factor in association with psychological distress. Objective: To explore the relationships between EI and stress, anxiety, and depression among a sample of US osteopathic medical students. Methods: From February to March 2020, a convenience sample of medical students enrolled at an osteopathic medical school in the southeastern region of the United States were invited to complete a voluntary and anonymous 54-item online questionnaire that included sociodemographic items as well as validated and reliable scales assessing perceived stress, anxiety, depression, and EI. Univariate statistics were calculated to describe the participant characteristics and the study variables of interest. Pearson's product-moment correlations were used to examine relationships between EI and study variables. Three multiple regression models were fitted to examine the relationship between EI and stress, anxiety, and depression, adjusting for sociodemographic factors exhibiting significant bivariate relationships with outcome variables. Dichotomous variables were created that were indicative of positive screens for potential depressive disorder or anxiety disorder. Independent-sample t-tests were used to determine the presence of a statistically significant difference in EI scores between positive screeners for depression and anxiety and their respective counterparts; an alpha level of 0.05 was set a priori to indicate statistical significance. Results: In all, 268 medical students participated in this study, for a response rate of approximately 27%. Importantly, EI exhibited significant negative correlations with stress, anxiety, and depression (r=-0.384, p<0.001; r=-0.308, p<0.001; r=-0.286, p<0.001), respectively). Thus, high levels of stress, anxiety, and depression were observed in the sample. Significant relationships remained following covariate adjustment. Established cutoffs for anxiety and depression were used to classify positive and negative screens for these morbidities. Using these classifications, individuals screening positive for potential anxiety and depression exhibited significantly lower levels of EI than their counterparts showing subclinical symptoms (t=5.14, p<0.001 and t=3.58, p<0.001, respectively). Conclusion: Our findings support the notion that higher levels of EI may potentially lead to increased well-being, limit psychological distress, improve patient care, and facilitate an ability to thrive in the medical field. We encourage continued study on the efficacy of EI training through intervention, measurement of EI in both academic and clinical settings as an indicator of those at risk for programmatic dropout or psychological distress, and consideration of EI training as an adjunct to the educational program curriculum.

RESUMO

INTRODUCTION: Previous studies indicated variability in the prevalence of Duchenne and Becker muscular dystrophies (DBMD) by racial/ethnic groups. The Centers for Disease Control and Prevention's (CDC) Muscular Dystrophy Surveillance, Tracking, and Research network (MD STARnet) conducts muscular dystrophy surveillance in multiple geographic areas of the USA and continues to enroll new cases. This provides an opportunity to continue investigating differences in DBMD prevalence by race and ethnicity and to compare the impact of using varying approaches for estimating prevalence. OBJECTIVE: To estimate overall and race/ethnicity-specific prevalence of DBMD among males aged 5-9 years and compare the performance of three prevalence estimation methods. METHODS: The overall and race/ethnicity-specific 5-year period prevalence rates were estimated with MD STARnet data using three methods. Method 1 used the median of 5-year prevalence, and methods 2 and 3 calculated prevalence directly with different birth cohorts. To compare prevalence between racial/ethnic groups, Poisson modeling was used to estimate prevalence ratios (PRs) with non-Hispanic (NH) whites as the referent group. Comparison between methods was also conducted. RESULTS: In the final population-based sample of 1,164 DBMD males, the overall 5-year prevalence for DBMD among 5-9 years of age ranged from 1.92 to 2.48 per 10,000 males, 0.74-1.26 for NH blacks, 1.78-2.26 for NH whites, 2.24-4.02 for Hispanics, and 0.61-1.83 for NH American Indian or Alaska Native and Asian or Native Hawaiian or Pacific Islander (AIAN/API). The PRs for NH blacks/NH whites, Hispanics/NH whites, and NH AIAN/API/NH whites were 0.46 (95% CI: 0.36-0.59), 1.37 (1.17-1.61), and 0.61 (0.40-0.93), respectively. CONCLUSIONS: In males aged 5-9 years, compared to the prevalence of DBMD in NH whites, prevalence in NH blacks and NH AIAN/API was lower and higher in Hispanics. All methods produced similar prevalence estimates; however, method 1 produced narrower confidence intervals and method 2 produced fewer zero prevalence estimates than the other two methods.

RESUMO

Psychiatric disorders are prevalent in dermatology patients. Psychodermatology is the body of knowledge at the intersection of psychiatry and dermatology practice. The purpose of this literature review was to assess the knowledge, attitudes, and practices of health care professionals regarding psychodermatology. A search of relevant articles was conducted in PubMed, CINAHL, ERIC, and PsychInfo databases using a comprehensive set of search terms. Studies were included if (1) study participants were health care professionals, (2) studies contained data that could be extracted, and (3) studies were published in peer-reviewed journals. A review of study findings was conducted. A total of nine studies were included in the review. Studies were conducted in several countries. Findings from the review confirmed that providers frequently reported psychocutaneous disorders in their practice. There were, however, gaps and variations in providers' knowledge base and level of comfort treating these patients. Further, providers acknowledged a lack of training in the practice of psychodermatology. The findings from this review suggest that health care professionals from multiple areas of the world may lack a full understanding, level of comfort, and proper training in psychodermatology. Improving the knowledge base and increasing level of comfort in treating psychodermatological disorders can improve the practice of psychodermatology amongst providers. Further, addressing knowledge and comfort level among providers through training and continuing education may improve outcomes for patients with psychocutaneous disorders.

RESUMO

OBJECTIVE: Research has not examined the use of health care by patients with myotonic muscular dystrophy (MMD), but it would provide insights into this population, which is prone to comorbidities and high service needs. This study is an analysis of this understudied subgroup, using a unique linked dataset to examine the characteristics and healthcare utilization patterns for people with MMD. METHODS: This analysis used 3 South Carolina datasets (2009-2014). The subjects included individuals with at least 1 encounter with an International Classification of Diseases, Ninth Revision, Clinical Modification code of 359.21. The variables included sex, race, visit type, payer, and diagnoses. The analyses examined characteristics and number of encounters. RESULTS: The subjects were predominately female, white, and 45 to 64 years old. A total of 44.6% of the study population had at least 1 inpatient visit, whereas 64.2% had at least 1 emergency department visit. A majority of the subjects had at least 1 office visit (55.0%), and most (85.3%) did not have a home health encounter. CONCLUSIONS: Investigation of the reasons for these inpatient and emergency department encounters may be helpful in identifying ways to deliver high-quality care.

RESUMO

PURPOSE: Studies have shown that children with muscular dystrophy are at increased risk for falls, however there is insufficient information about what predicts the first and subsequent events. The purpose of this study was to describe the experience of injury with emphasis on identifying risk factors for fall-related injuries. METHODS: We studied 269 boys with muscular dystrophy describing their injury experience and identifying risk and protective factors associated with 281 non-simultaneous injuries and 127 falls that resulted in Emergency Department visits and/or inpatient hospitalization during the period 1998-2014. We used a Cox model to estimate the predictors of an initial fall and a zero-inflated Poisson model to identify the predictors for the number of falls. RESULTS: Falls accounted for the greatest number of injury occurrences; The most frequent injury type was contusion. The factors that were protective for falls were steroid use, wheelchair use, or having a heart condition. Baseline age was negatively associated with the risk of having any fall, but not significantly related to subsequent falls. CONCLUSION: Wheelchair use and heart conditions associated with reduced risk of falls likely reflects decreased mobility. Clinicians should help families identify factors associated with falls among those who remain ambulatory.

RESUMO

BACKGROUND: There is a need to examine health care utilization of individuals with the rare conditions muscular dystrophies, spina bifida, and fragile X syndrome. These individuals have a greater need for health care services, particularly inpatient admissions. Prior studies have not yet assessed 30-day all-cause readmission rates. OBJECTIVE: To estimate 30-day hospital readmission rates among individuals with three rare conditions. HYPOTHESIS: Rare conditions patients will have a higher 30-day all-cause readmission rate than those without. METHODS: Data from three sources (2007-2014) were combined for this case-control analysis. A cohort of individuals with one of the three conditions was matched (by age in 5 year age groups, gender, and race) to a comparison group without a rare condition. Inpatient utilization and 30-day all-cause readmission rates were compared between the two groups. Logistic regression analyses compared the odds of a 30-day all-cause readmission across the two groups, controlling for key covariates. RESULTS: A larger proportion in the rare condition group had at least one inpatient visit (46.1%) vs. the comparison group (23.6%), and a higher 30-day all-cause readmission rate (Spina Bifida-46.7%, Muscular Dystrophy-39.7%, and Fragile X Syndrome-35.8%) than the comparison group (13.4%). Logistic regression results indicated that condition status contributed significantly to differences in readmission rates. CONCLUSIONS: Higher rates of inpatient utilization and 30-day all-cause readmission among individuals with rare conditions vs. those without are not surprising, given the medical complexity of these individuals, and indicates an area where unfavorable outcomes may be improved with proper care coordination and post discharge care.

RESUMO

BACKGROUND: Food allergy is a significant public health concern in the United States, especially in the pediatric population. It places substantial clinical and economic burdens on the health care system. Exposure to antibiotics in early childhood is thought to increase the risk of subsequent food allergy. OBJECTIVE: To examine the impact of exposure to antibiotics early in life on time to development of food allergy. METHODS: We conducted a population-based matched cohort study using Medicaid data from 28 states. Antibiotic nonusers were matched 1:1 to antibiotic users on date of birth, sex, race, and state. A Cox proportional hazards regression model was used to evaluate the effect of antibiotic exposure on time to development of food allergy. Sensitivity analyses were performed to assess the robustness of study findings. RESULTS: We matched 500,647 antibiotic nonusers to 500,647 antibiotic users in the Medicaid pediatric population. In the adjusted Cox proportional hazards regression analysis, antibiotic exposure was significantly associated with faster development of food allergy (hazard ratio, 1.40; 95% CI, 1.34-1.45). The magnitude and significance of the association between antibiotic exposure and food allergy did not change in the sensitivity analyses. A significant association between antibiotic exposure and faster development of food allergy was found in 17 of 28 states. CONCLUSION: Compared with antibiotic nonusers, children with antibiotic prescription had an increased risk of food allergy.

RESUMO

OBJECTIVE: The objective of this study was to evaluate secular trends in Dietary Inflammatory Index (DII) scores in the United States between 1999 and 2014. METHODS: Data from adults over 19 years from the 1999 to 2014 National Health and Nutrition Examination Survey (N = 39,191) were used. DII scores, at each 2-year cycle, were evaluated from a 24-h recall, including 26 food parameters for DII calculation. Analyses were conducted in 2018. RESULTS: For the entire sample, there was a quadratic trend (Ptrend < 0.001), with the DII scores peaking in 2003-2004, and then decreasing during the cycles from 2005 to 2014. Similar quadratic trends (Ptrend < 0.001) were observed by age, gender, race-ethnicity, and education. CONCLUSION: Males, non-Hispanic Blacks, younger adults, and those with less education adults had the highest DII scores (i.e., indicating the greatest inflammatory potential). The overall DII scores of the US population showed a quadratic trend from 1999 to 2014. Continued monitoring of DII changes is needed to better understand changes in the inflammatory potential of diet of American adults, and how they relate to changes in the risk of chronic disease.

RESUMO

The objective of this study was to investigate whether males who were born preterm took longer to receive a Duchenne muscular dystrophy diagnosis than term males. Data for males with Duchenne muscular dystrophy identified through a population-based surveillance system were analyzed using a Kaplan-Meier estimator. The first signs and symptoms were noted at a median age of 2 years in both groups. Median age when first signs and symptoms prompted medical evaluation was 2.59 years among preterm and 4.01 years among term males. Median age at definitive diagnosis was 4.25 years and 4.92 years for preterm and term males, respectively. Neither difference was statistically significant. Preterm males tended to be seen for their initial medical evaluation earlier than term males, though they were not diagnosed significantly earlier. It may take clinicians longer after the initial evaluation of preterm males to arrive at a Duchenne muscular dystrophy diagnosis.

RESUMO

BACKGROUND/AIMS: Duchenne Muscular Dystrophy (DMD) has childhood onset, primarily affects males, and is usually fatal before the age of 40 years. Previous studies have indicated that this X-linked condition is more prevalent in whites than in blacks, but those were based on active surveillance, and limited to smaller populations and younger ages. METHODS: US death data were used to calculate mortality rates by race and ethnicity, with MD as either the underlying or multiple cause of death (MCD). Poisson approximation was used for confidence intervals; chi-square was used to compare rates. RESULTS: From 2006 to 2015, there were 3,256 deaths in males <40 years with MD as MCD, and 71% of these were aged 15-29 years. For whites, the average annual death rate was 0.43/100,000, which was significantly higher (p < 0.0001) that that of blacks (0.28), American Indian/Alaska Natives (0.20), and Asian/Pacific Islanders (0.21). The rate for non-Hispanic whites (0.46) was significantly higher (p < 0.0001) than the rates for Hispanic whites (0.31), Hispanic blacks (0.07), and non-Hispanic blacks (0.29). CONCLUSION: Since DMD is the primary cause of deaths in young males with MD, mortality rates are a reasonable proxy for the relative difference in racial prevalence. It appears that DMD is significantly more common in white males than in males of other races.

RESUMO

OBJECTIVE: Both diet and physical activity have been shown to be associated with reduced risk for mortality. The current study examined the individual and combined effects of the inflammatory quality of diet and physical activity levels on mortality risk. METHODS: Data from the 1999-2004 National Health and Nutrition Examination Survey were used (N = 10,610 adults 20-85 years). Participants were followed through 2011, entailing a median follow-up time of 9.6 yrs. Dietary patterns were assessed using the Dietary Inflammatory Index (DII®), with a higher score indicative of greater diet-related inflammation. Habitual physical activity was assessed via a 30-day recall of leisure-time physical activity as well as objectively via up to seven days of accelerometry assessment. Four lifestyle groups were created: 1) unfavorable DII and inactive (referent); 2) unfavorable DII and active; 3) favorable DII and inactive; and 4) favorable DII and active. RESULTS: Those who had a low DII score (favorable) and who self-reported being active had a 39% reduced hazard of all-cause mortality (HR = 0.61; 95% CI: 0.49-0.76) when compared to those with a higher DII and were inactive. Results based on accelerometer-assessed physical activity indicate a 65% reduced hazard (HR = 0.35; 95% CI: 0.17-0.74). DII and physical activity also were individually associated with mortality in the expected direction. Specifically, DII was positively associated (HR = 1.08; 95% CI: 1.04-1.13) and physical activity inversely associated (HR = 0.97; 95% CI: 0.94-0.99) with all-cause mortality risk. CONCLUSION: The combination of consuming a more anti-inflammatory diet and having adequate levels of physical activity is associated with a reduced risk of mortality. Additional replicative work is warranted.

RESUMO

Effective emotional regulation is critical for overall psychological well-being; as such, it is important to investigate potential methods to optimize emotion regulation abilities. The purpose of this study was to examine the effects of an acute bout of aerobic exercise and meditation on emotional regulation among young adults. Participants (N=63, mean age=21.3yrs) were randomly assigned to stretch (control group, n=21), walk (n=21), or meditate (n=21) for 10-min, after which they were exposed to a film clip (3min) intended to elicit a negative emotional state (e.g., sadness, anger). Participants then viewed 12 International Affective Picture System images validated to elicit a negative valence. Participants' affect (valence and arousal) states were monitored before, during, and after the stretching, walking, and meditation bouts using the Feeling Scale (FS) and Felt Arousal Scale (FAS). Distinct affect was assessed utilizing an affective circumplex measure before and after the stretch/walk/meditation bout, as well as following the film clip and image viewing. A significant group×time interaction effect was present when evaluating circumplex excited: P=0.001 (η2=0.21). Additionally, an interaction effect of meditation and emotional regulation was observed (P=0.009) among those with varying degrees of meditation experience. A 10-min bout of brisk walking and meditation, prior to exposure to a negative emotion cue, did not differentially effect the ability to regulate sadness, anger, or anxiousness when compared to an active stretching control group. Future replicative work addressing this paradigm, which is in support of positive psychology theory, is warranted.

RESUMO

The objective of this study was to examine the association between dietary inflammatory potential and memory and cognitive functioning among a representative sample of the US older adult population. Cross-sectional data from the 2011-2012 and 2013-2014 National Health and Nutrition Examination Survey were utilised to identify an aggregate sample of adults 60-85 years of age (n 1723). Dietary inflammatory index (DII®) scores were calculated using 24-h dietary recall interviews. Three memory-related assessments were employed, including the Consortium to Establish a Registry for Alzheimer's disease (CERAD) Word Learning subset, the Animal Fluency test and the Digit Symbol Substitution Test (DSST). Inverse associations were observed between DII scores and the different memory parameters. Episodic memory (CERAD) (b adjusted=-0·39; 95 % CI -0·79, 0·00), semantic-based memory (Animal Fluency Test) (b adjusted=-1·18; 95 % CI -2·17, -0·20) and executive function and working-memory (DSST) (b adjusted=-2·80; 95 % CI -5·58, -0·02) performances were lowest among those with the highest mean DII score. Though inverse relationships were observed between DII scores and memory and cognitive functioning, future work is needed to further explore the neurobiological mechanisms underlying the complex relationship between inflammation-related dietary behaviour and memory and cognition.
