RESUMEN

The impact of conflict and crisis on maternal and child health underscores the need for reliable research in vulnerable populations. Lebanon, amidst ongoing economic collapse, political instability, and healthcare system strain, offers a case study for exploring these impacts, particularly on preterm babies and their development. This study aims to assess the feasibility of establishing a prospective cohort of mothers and their full-term and preterm babies in Lebanon, examining the association between social determinants, preterm birth, and developmental outcomes amidst the nation's multifaceted crises. The planned cohort involves 50 full-term and 50 preterm mother-baby pairs recruited at birth and followed up to 9-12 months post-birth. Data collection spans social determinants, perceived stress, social support, quality of life, and developmental assessments. Challenges in recruitment, follow-up, and data collection in the context of Lebanon's socio-political and economic turmoil are evaluated, alongside ethical considerations for research in vulnerable populations. Preliminary findings highlight substantial recruitment and follow-up challenges, notably due to population mobility, economic instability, and healthcare access issues. Despite these obstacles, 113 mother-baby pairs have been recruited. Early analysis reveals significant stress and reduced quality of life among mothers, particularly those with preterm infants, against a backdrop of declining birth rates and healthcare worker exodus. Conducting research in crisis settings like Lebanon presents unique methodological and ethical challenges but remains crucial for understanding and improving health outcomes in vulnerable populations. The study underscores the importance of adaptable research designs and ethical diligence in crisis research, highlighting the need for interventions tailored to these contexts. Establishing a mother and child cohort in Lebanon's crisis-ridden setting is faced with many challenges but is essential for guiding future interventions. Research in such contexts is needed to address health disparities and supporting vulnerable populations, emphasizing the need for dedicated funding and innovative research approaches in times of crisis.

RESUMEN

BACKGROUND: Magnetic resonance imaging (MRI) studies have identified brain changes associated with anxiety disorders (ADs), but the results remain mixed, particularly at a younger age. One key predictor of ADs is behavioral inhibition (BI), a childhood tendency for high avoidance of novel stimuli. This study aimed to evaluate the relationships between candidate brain regions, BI, and ADs among children using baseline data from the Adolescent Brain Cognitive Development (ABCD) study. METHODS: We analyzed global and regional brain volumes of 9,353 children (9-10 years old) in relation to BI and current ADs, using linear mixed models accounting for family clustering and important demographic and socioeconomic covariates. We further investigated whether and how past anxiety was related to brain volumes. RESULTS: Among included participants, 249 (2.66%) had a current AD. Larger total white matter (Beta = -0.152; 95% CI [-0.281, -0.023]), thalamus (Beta = -0.168; 95% CI [-0.291, -0.044]), and smaller hippocampus volumes (Beta = 0.094; 95% CI [-0.008, 0.196]) were associated with lower BI scores. Amygdala volume was not related to BI. Larger total cortical (OR = 0.751; 95% CI [0.580;0.970]), amygdala (OR = 0.798; 95%CI [0.666;0.956]), and precentral gyrus (OR = 0.802; 95% CI [0.661;0.973]) volumes were associated with lower odds of currently having ADs. Children with past ADs had smaller total white matter and amygdala volumes. CONCLUSIONS: The results show associations between brain volumes and both BI and ADs at an early age. Importantly, results suggest that ADs and BI have different neurobiological correlates and that earlier occurrences of ADs may influence brain structures related to BI and ADs, motivating research that can better delineate the similarities and divergence in the neurobiological underpinnings and building blocks of BI and ADs across their development in early life.

RESUMEN

BACKGROUND: Psychopathy has been described as "the first personality disorder to be recognized in psychiatry". It has three core features: affective, interpersonal, and behavioral. The Levenson Self-Report Psychopathy (LSRP) scale is used to screen for and measure psychopathy. Our study aims to validate the LSRP as a tool to measure psychopathy in the non-institutionalized Lebanese population. METHODS: We surveyed Lebanese individuals residing in Lebanon and aged 18 through 65. It was a convenience sample collected via an online survey. 534 Lebanese participants completed the survey and were included in our analyses. Nearly 80% were female, 90% were college educated, and 60% were employed. We used exploratory graph analysis and confirmatory factor analyses to measure internal validity of the LSRP. We also used the HEXACO Personality Inventory-Revised (HEXACO-PI-R), the Subtypes of Antisocial Behavior Questionnaire (STAB), and the Short version of the Urgency, Premeditation (lack of), Perseverance (lack of), Sensation Seeking, Positive Urgency, Impulsive Behavior Scale (S-UPPS-P) to measure external validity of LSRP. RESULTS: The exploratory graph analysis showed that the LSRP had a three-factor structure (Egocentric, Callous and Antisocial) in the Lebanese population. This three-factor structure (RMSEA = 0.05, CFI = 0.83, SRMR = 0.06) yielded a better fit than the two-factor, and three-factor Brinkley models. The LSRP was negatively correlated with the Honesty-Humility dimension of the HEXACO-PI-R and positively correlated with the STAB and S-UPPS-P subscales. CONCLUSIONS: The LSRP scale is a valid measure of psychopathy in the Lebanese non-institutionalized population, adding to the currently limited literature addressing psychopathy in the Arab World.

RESUMEN

This study aims to describe daytime sleepiness and health-related quality of life (HRQoL) among Lebanese kidney transplant (KT) recipients and to examine the medical, psychosocial and transplant factors related to them. It is a cross-sectional multi-center study involving KT recipients >18 years. Daytime sleepiness was assessed using ESS Questionnaire. HRQoL was measured using the SF-36 questionnaire. Social support was self-reported. A multivariable regression analysis evaluated factors associated with daytime sleepiness and HRQoL in our sample. 118 patients were recruited over a 2 years period. Excessive daytime sleepiness was prevalent in 12.7%. It was associated with Diabetes Mellitus (OR 3.97, 95% CI 0.94-16.81, p = 0.06) and obesity (OR 1.13, 95% CI 1.02, 1.27, p = 0.02). Social support and higher eGFR were associated with better scores on the MCS (ß 24.13 p < 0.001 and ß 0.26 p < 0.01) and the PCS (ß 15.48 p < 0.01 and ß 0.22 P 0.02). Conversely, depression and hospitalization were negatively associated with the MCS (ß -27.44, p < 0.01 and ß -9.87, p < 0.01) and the PCS (ß -0.28.49, p < 0.01 and ß -10.37, p < 0.01).

RESUMEN

Racial residential segregation is associated with multiple adverse health outcomes in Black individuals. Yet, the influence of structural racism and racial residential segregation on brain aging is less understood. In this study, we investigated the association between cumulative exposure to racial residential segregation over 25 years (1985-2010) in young adulthood, as measured by the Getis-Ord Gi* statistic, and year 25 measures of brain volume (cerebral, gray matter, white matter, and hippocampal volumes) in midlife. We studied 290 Black participants with available brain imaging data who were enrolled in the Coronary Artery Risk Development in Young Adults (CARDIA) Study, a prospective cohort study. CARDIA investigators originally recruited 2,637 Black participants aged 18-30 years from 4 field centers across the United States. We conducted analyses using marginal structural models, incorporating inverse probability of treatment weighting and inverse probability of censoring weighting. We found that compared with low/medium segregation, greater cumulative exposure to a high level of racial residential segregation throughout young adulthood was associated with smaller brain volumes in general (e.g., for cerebral volume, ß = -0.08, 95% confidence interval: -0.15, -0.02) and with a more pronounced reduction in hippocampal volume, though results were not statistically significant. Our findings suggest that exposure to segregated neighborhoods may be associated with worse brain aging.

RESUMEN

INTRODUCTION: Psychiatric disorders are among the leading causes of disability in children and adolescents globally. In Lebanon, a country that has endured a prolonged history of conflict and economic and political uncertainty, mental health surveys in children and adolescents have been limited to specific disorders or specific settings or cities. PALS (Psychopathology in Children and Adolescents in Lebanon Study) is the first study to screen a nationally representative sample of children and adolescents for psychiatric disorders and estimate the national prevalence of children and adolescents at risk of having a psychiatric disorder. METHODS: A nationally representative household sample of 1517 children and adolescents (aged 5 years 0 months to 17 years 11 months) was recruited through a multi-stage stratified proportionate sampling technique between February 2018 and November 2018. Parents and adolescents completed a battery of self-reported scales including the Strengths and Feelings Questionnaire (SDQ), Mood and Feelings Questionnaire (MFQ), Screen for Child Anxiety and Emotional Related Disorders (SCARED), the Peer Relations Questionnaire (PRQ), General Health Questionnaire (GHQ), and Conflict Behavior Questionnaire (CBQ), Child Revised Impact of Events Scale (CRIES), and a demographic/clinical information questionnaire. Logistic regression models were used to examine the correlates of screening positive for psychiatric disorders. RESULTS: About a third of children and adolescents (32.7%, n = 497) screened positive for at least one psychiatric disorder, of whom only 5% (n = 25) reported ever seeking professional mental health help. Academic performance, having a chronic physical illness, higher parental GHQ scores, and involvement in bullying were associated with a higher odds of screening positive for a psychiatric disorder. Higher family income was negatively associated with screening positive for a psychiatric disorder. CONCLUSION: This first national study shows a high prevalence of psychiatric symptoms in Lebanese children and adolescents and an alarming treatment gap. School-based primary prevention programs or screening in primary care settings are key for early detection and management of psychiatric symptoms, and prevention of psychiatric disorders.

RESUMEN

Parenting programs aim to help parents and carers enhance their skills and ameliorate infants' and toddlers' wellbeing. In Lebanon and other Arab countries, contextualized group-based parenting programs addressing parents' mental wellbeing, parenting styles, and child development are quite rare. Therefore, a Preventive Parenting Program consisting of 7 sessions has been designed by local experts for the local cultural context. This study aims to assess its effectiveness. Thirty-three sites were identified in Great Beirut: private firms, primary healthcare centers, and child daycares. Sixteen agreed to take part in the study and were randomly assigned to intervention and control arms. From these clusters, 191 mothers of typically developed children younger than three years were recruited to intervention (106) or control (85) groups. The Mental Health Inventory, Caregiver Knowledge about Child Development Inventory, Parent Authority Questionnaire, and a Demographic questionnaire were completed at pre-intervention and post-intervention and 3 months later by both groups of mothers. There were no significant differences between clusters with respect to all scales' scores at baseline as well as the 2 other data collection points. Despite the positive feedback collected from mothers who attended the sessions, no significant effects were detected. The design of the program, the expected outcomes, and the characteristics of the participants may have contributed to the limited results, hence the need for further research.

RESUMEN

BACKGROUND AND AIM: Traditionally, practical skills are taught on face-to-face (F-F) basis. COVID-19 pandemic brought distance learning (DL) to the spotlight because of the social distancing mandates. We sought to determine the acceptability and effectiveness of DL of basic suturing in novice learners. METHODS: A prospective randomized controlled trial involving 118 students was conducted. Participants were randomized into two groups for learning simple interrupted suturing: F-F and DL-groups. Evaluation was conducted by two assessors using a performance checklist and a global rating tool. Agreement between the assessors was calculated, and performance scores of the participants were compared. Participants' satisfaction was assessed via a questionnaire. RESULTS: Fifty-nine students were randomized to the F-F group and 59 to the DL-group. Satisfactory agreement between the assessors was demonstrated. All participants were successful in placing three interrupted sutures, with no significant difference in the performance between the groups. 25(44.6%) of the respondents in the DL-group provided negative comments related to the difficulties of remotely learning visuospatial concepts, 16(28.5%) preferred the F-F approach. CONCLUSION: DL of basic suturing is as effective as the F-F approach in novice learners. It is acceptable by the students despite the challenges related to the remote learning of practical skills.

RESUMEN

BACKGROUND: Despite the growing burden of Alzheimer's disease and related dementias (ADRD) in low- to middle-income countries (LMICs) and prior findings of important gaps in research on ADRD knowledge, very few studies have assessed ADRD knowledge in these populations. This study evaluates the knowledge and attitudes towards ADRD among Lebanese middle-aged and older adults. METHOD: Participants aged ≥ 40 (n = 215) attending primary care clinics at a large medical centre in Lebanon completed the Alzheimer's Disease Knowledge Scale (ADKS), an attitude scale, and the Duke University Religion Index. RESULTS: ADRD knowledge accuracy was 61.5% (mean score = 18.6 out of 30 (SD = 3.05)). Items with the least correct answers were related to caregiving and risk factors (≤9% and ≤28%). Overall, participants had tolerant views concerning ADRD; the least positive views were regarding living with people with ADRD. Older age, lower educational attainment, and higher religiosity scores were associated with poorer knowledge and attitudes. CONCLUSION: Results highlight the need for awareness and preventive efforts that address misconceptions about modifiable risk factors and living with ADRD, especially given that the burden of caregiving for older adults often falls on family members in Lebanon and other LMIC countries.

RESUMEN

OBJECTIVES: Ischemic stroke is a common cause of morbidity and mortality especially in the increasingly older population. The variability in ischemic stroke subtypes and its risk factors across different populations suggest that more effort is needed to describe the stroke characteristics in order to develop a more tailored management for each population. We aim to describe the demographic characteristics, risk factors, and subtype distribution of subjects with ischemic stroke in the Lebanese population. MATERIALS AND METHODS: We conducted a cross-sectional study based on chart review on patients with ischemic stroke/transient ischemic attack at the American University of Beirut Medical center between 2015 and 2017. RESULTS: A total of 284 cases were included with a mean age of 72 years, and 58% male gender. The most commonly identified risk factors were hypertension (77%), dyslipidemia (62%), and diabetes mellitus (42%), while atrial fibrillation was only found in 27% of cases. The cohort distribution according to TOAST classification was as follows: 15% large artery stroke, 31% cardioembolic stroke, 17% small artery stroke, 10% stroke of other determined causes, and 27% stroke of unknown cause. CONCLUSION: This is the first study to address ischemic stroke characteristics in Lebanon.

RESUMEN

INTRODUCTION: In addition to well-established links with cardiovascular and respiratory diseases, cigarette smoking may affect skeletal muscle; however, associations with quadriceps atrophy, density, and function are unknown. This study explored the associations of current and former smoking with quadriceps muscle area and attenuation as well as muscle force (assessed as knee extension peak torque) and rate of torque development-a measure of muscle power in older adults. METHODS: Data from 4469 older adults, aged 66-95 years at baseline in the Age, Gene/Environment Susceptibility-Reykjavik Study with measurements of thigh computed tomography, isometric knee extension testing, self-reported smoking history, and potential covariates were analyzed. RESULTS: Sex differences were observed in these data; therefore, our final analyses are stratified by sex. In men, both former smokers and current smokers had lower muscle area (with ß= -0.10, 95% confidence interval [CI] = -0.17 to -0.03 and ß = -0.19, 95% CI = -0.33 to -0.05, respectively) and lower muscle attenuation (ie, higher fat infiltration, ß = -0.08, 95% CI = -0.16 to -0.01 and ß = -0.17, 95% CI = -0.34 to -0.01, respectively) when compared with never smokers. Smoking status was not associated with male peak torque or rate of torque development. In women, current smoking was associated with lower muscle attenuation (ß = -0.24, 95% CI = -0.34 to -0.13) compared to never smoking. Among female smokers (current and former), muscle attenuation and peak torque were lower with increasing pack-years. CONCLUSIONS: Results suggest that cigarette smoking is related to multiple muscle properties at older age and that these relationships may be different among men and women. IMPLICATIONS: This article presents novel data, as it examined for the first time the relationship between smoking and computed tomography-derived quadriceps muscle size (cross-sectional area) and attenuation. This study suggests that current cigarette smoking is related to higher muscle fat infiltration, which may have significant health implications for the older population, because of its known association with poor physical function, falls, and hip fractures.

RESUMEN

BACKGROUND: Worldwide, studies show a relationship between nurses' health and some work environment factors; however, data on nurses' health and self-perceived workload and nursing task allocation are lacking, particularly for Lebanese nurses. We assessed the relationship of several work environment factors: overall workload and specific temporal, physical, mental, effort, frustration, and performance demands (NASA Task Load Index), staffing resources and adequacy and leadership (Practice Environment Scale of Nursing Work Index), teamwork climate (Safety Attitudes Questionnaire), and nursing task allocation (Basel Extent of Rationing of Nursing Care)) with self-reported musculoskeletal, cardiovascular, skin, and mental health diseases (Work Ability Index) and emotional exhaustion (Maslach Burnout Inventory) among Lebanese nurses. METHODS: A cross-sectional self-report survey was distributed to all 289 registered nurses (RNs) in the medical, surgical, and pediatric units in two Lebanese university-affiliated hospitals; 170 RNs had complete data. Adjusted multivariable logistic regression models were used to estimate the association between work environment factors and health outcomes. RESULTS: The most prevalent outcomes were musculoskeletal disease (69%), emotional exhaustion (59%), and mental health problems (56%); 70% of RNs had ≥2 and 35.29% had ≥4 co-occurring health problems. Musculoskeletal disease was associated with higher overall (OR = 1.36 (95%CI = 1.03, 1.80)), temporal (OR = 1.30 (95%CI = 1.09, 1.55)), and physical demands (OR = 1.20 (95%CI = 1.03, 1.49)), higher task allocation to RNs (OR = 1.11 (95%CI = 1.01, 1.23)) and lower teamwork climate (OR = 0.60 (95%CI = 0.36, 0.98). Higher odds of mental/emotional problems were associated with higher overall, temporal, frustration, and effort demands, and lower teamwork climate, performance satisfaction, and resources adequacy (increased odds ranging from 18 to 88%). Work environment indicators were associated with higher co-occurrence of health problems. CONCLUSIONS: Results show elevated health burden and co-morbidity among Lebanese RNs and highlight the value of comprehensive approaches that can simultaneously improve several work environment factors (namely self-perceived workload, teamwork,, resources, and nursing task allocation) to reduce this burden.

RESUMEN

BACKGROUND: Implicit rationing of nursing care is associated with work environment factors. Yet a deeper understanding of trends and variability is needed. AIMS: To explore the trends and variability of rationing of care per shift between individual nurses, services over time, and its relationship with work environment factors. METHODS: Longitudinal study including 1,329 responses from 90 nurses. Intraclass correlation coefficients (ICC) were computed to examine variability of rationing per shift between individual nurses, services, and data collection time; generalized linear mixed models were used to explore the relationship with work environment factors. RESULTS: Percentage of rationing of nursing activities exceeded 10% during day and night shifts. Significant variability in rationing items was observed between nurses, with ICCs ranging between 0.20 and 0.59 in day shifts, and between 0.35 and 0.85 in night shifts. Rationing of care was positively associated with nurses' self-perceived workload in both shifts, but not with patient-to-nurse ratios. CONCLUSION: Most variability in rationing over time was explained by the individual. IMPLICATIONS FOR NURSING MANAGEMENT: Nurse managers and leaders need to develop and implement educational programs on implicit rationing of nursing care to strengthening nurses' skills related to decision-making, prioritization and time management.

RESUMEN

INTRODUCTION: Infectious agents were recently implicated in Alzheimer's disease (AD) and etiology of other dementias, notably Helicobacter pylori. METHODS: We tested associations of H. pylori seropositivity with incident all-cause and AD dementia and with AD-related mortality among US adults in a retrospective cohort study. Data from the National Health and Nutrition Surveys III, phase 1 (1988-1991) and 1999-2000 linked with Medicare and National Death Index registries, were used (baseline age ≥45 y, follow-up to 2013, Npooled = 5927). RESULTS: A positive association between H. pylori seropositivity and AD mortality was found in men (hazard ratioadj, pooled = 4.33, 95% confidence interval: 1.51-12.41, P = .006), which was replicated for incident AD and all-cause dementia, with hazard ratioadj, pooled = 1.45 (95% confidence interval: 1.03-2.04, P = .035) and hazard ratioadj, III = 1.44 (95% confidence interval: 1.05-1.98, P = .022), respectively. These associations were also positive among higher socioeconomic status groups. DISCUSSION: In sum, H. pylori seropositivity's direct association with AD mortality, all-cause dementia, and AD dementia was restricted to men and to higher socioeconomic status groups.

RESUMEN

OBJECTIVE: Low socioeconomic position (SEP) has been linked to an increased risk of dementia and cognitive decline. However, little is known about the association between SEP and morphologic brain changes in older age. This study examines the relationships between indicators of life-course SEP with both hippocampal volume (HcV) and HcV loss in a population-based cohort of 1328 older adults aged 65 to 80 years. METHODS: Multivariable linear regression models were used to estimate the associations of SEP with baseline HcV and the annual rate of HcV atrophy according to three life-course conceptual models: the sensitive/critical periods model (which explored SEP in specific periods: in childhood [using parental education], early adulthood [based on participants' education], and midlife [based on participants' socioprofessional group]); the accumulation-of-risk model (life-course cumulative SEP), and the social mobility model (life-course SEP trajectories). RESULTS: Participants with lower midlife SEP had smaller HcV (-0.08 cm; 95% confidence interval, -0.15 to -0.01) and 0.17% (95% confidence interval, 0.04%-0.30%) faster hippocampal atrophy than participants with higher midlife SEP. Childhood and early adulthood SEPs were not related to hippocampal measures. The accumulation-of-risk and the social mobility models revealed that the accumulation of socioeconomic disadvantage and declining socioeconomic trajectories were related to faster hippocampal atrophy. CONCLUSIONS: In this cohort of older adults, lower socioprofessional attainment in midlife and disadvantageous life-course socioeconomic position were associated with faster hippocampal atrophy, a cerebral change linked to cognitive disorders. Results support the hypothesized links between socioenvironmental exposures related to stress and/or cognitive enrichment and brain/cognitive reserve capacities.

RESUMEN

Several studies have reported smaller hippocampal volume in patients with depression. However, the temporality of the association is undetermined. One hypothesis is that hippocampal atrophy might be a susceptibility factor for depression. In the present study, we assessed whether hippocampal atrophy was associated with subsequent depressive symptoms in a cohort of older French adults (n = 1,309) who were 65-80 years of age and enrolled into the study in 1999-2001 in Dijon, France. Subjects were followed for more than 10 years. Participants underwent 2 cerebral magnetic resonance imaging scans, one at baseline and one at the 4-year follow-up. We used linear mixed models to estimate the associations of hippocampal atrophy with 1) the average depressive symptom scores over follow-up (using the Center for Epidemiologic Studies-Depression scale) measured biennially over the subsequent 6 years and 2) changes in symptom scores over follow-up. In women, a 2-standard-deviation increase in annual hippocampal atrophy was associated with a 1.67-point (95% confidence interval: 0.59, 2.77) increase in the average depressive symptom score over follow-up and with a 1.97-point (95% confidence interval: 0.68, 3.24) increase in scores over the 2 subsequent years but not with later changes in symptoms. No association was detected in men. Accounting for potential selective attrition (using inverse probability weights) did not alter results. Hippocampal atrophy was associated with more subsequent depressive symptoms and with shorter-term worsening of symptoms in women.

RESUMEN

Background: Parents have a significant role in supporting children who have been exposed to traumatic events. Little is known about parental experiences and needs in the wake of traumatic exposure, which could help in designing tailored early interventions.Objective: This qualitative study explored experiences, perceived needs, and factors impacting those needs being met, in parents of adolescents aged 11-16 years who had been exposed in the past 3 months to a potentially traumatic event, in the city of Montpellier, France.Method: We purposively sampled 34 parents of 25 adolescents aged 11-16 years meeting the inclusion criteria and used semi-structured in-depth interviews. Thematic analysis was applied using a multistage recursive coding process.Results: Parents lacked trauma-informed explanations to make sense of their child's reduced functioning. They experienced stigma attached to the victim label and were reluctant to seek help. School avoidance and lack of collaboration with schools were major obstacles experienced by parents. Parents trying to navigate conflicting needs fell into two distinct categories. Those who experienced distressing levels of shame and guilt tended to avoid discussing the traumatic event with their child, pressuring them to resume life as it was before, despite this perpetuating conflictual interactions. Others adapted by revisiting their beliefs that life should go on as it was before and by trying to come up with new functional routines, which improved their relationship with their child and helped them to restore a sense of agency and hope, but at the cost of questioning their parental role.Conclusions: Key domains of parental experiences could provide potential early intervention targets, such as psychoeducation on traumatic stress, representations about recovery and the victim status, parent-child communication, and involvement of schools and primary caregivers. Further research is needed to validate the impact of these domains in early post-traumatic interventions.


Parents of teenagers exposed to traumatic events struggle to understand trauma and feel isolated.Parents feel pressured to resume life as it was before, leading to conflictual child­parent interaction.Psychoeducation, stigma, and school involvement could be early intervention targets.

RESUMEN

Background: The incidence of colonic adenomas and colorectal cancer has been on the rise among young patients. In this study, we aimed to describe the characteristics of young patients (<50 years) with adenomatous polyps and to characterize those polyps. We also aimed to determine appropriate surveillance intervals for young patients. Methods: We performed a retrospective chart review of patients <50 years of age who had polypectomy of 1 or more adenomatous polyps on colonoscopy between 2008 and 2021. Patient demographics, colonoscopy indication and polyp characteristics were obtained from the chart. Timing and findings on surveillance colonoscopies were recorded. Results: A total of 610 patients were included: mean age 42.9±5.9 years, 61% males, body mass index 27.5±4.7 kg/m2, and over 50% smokers. The most common indications were abdominal pain (23.3%), rectal bleeding (22.3%), and change in bowel habits (17.6%). Almost half of the patients who had adenomas (299) were younger than 45 years. Tubular adenoma was the most frequently encountered type of polyp (571; 93.6%). Mean polyp size was 1.1±0.9 cm. The most common location of adenomas was the sigmoid colon (41%). Of patients with adenomas, 156 (26%) had surveillance colonoscopy within 2.9±2.3 years; 74 patients (47.4%) were found to have new adenomas. Conclusions: Patients aged <50 years with colonic adenomas were mostly males, overweight, and smokers. Further adenomas were found in 47% of surveillance colonoscopies, and most were encountered within 5 years. High rates of recurrent adenomas in people <50 years of age may warrant frequent surveillance.

RESUMEN

BACKGROUND AND OBJECTIVES: The nature of associations between depressive symptoms and cognition early in the life course remains unclear, and racial differences in these associations are not well characterized. The aim of this study was to examine the relationship between trajectories of depressive symptom over 20 years, beginning in young adulthood, and cognitive functions in middle-age among Black and White adults. METHODS: We used prospective data from participants of the Coronary Artery Risk Development in Young Adults Study. Depressive symptoms were measured at 5 study visits between 1990 and 2010 using the Center for Epidemiologic Studies Depression scale. We used latent class group-based modeling to identify 4 trajectories: "persistently low," "persistently medium," "medium decreasing," and "high increasing" depressive symptoms. In 2015, cognitive function was measured using the Digit Symbol Substitution Test (DSST), Stroop test (reverse coded), and Rey Auditory-Verbal Learning Test (RAVLT).We excluded participants who missed the cognitive battery or had no depressive symptoms measurements, resulting in a total of 3,117 participants. All cognitive tests were standardized, and linear regression was used to relate depressive trajectories with 2015 cognitive functions. RESULTS: The mean [SD] baseline age was 30.1 [3.6] years, and 57% were female. The associations between depressive symptoms and cognition significantly differed by race (p < 0.05). Among Black individuals, compared with having "persistently low," having "medium decreasing," "persistently medium," or "high increasing" depressive symptoms were associated with worse verbal memory, processing speed, and executive function scores (RAVLT persistently medium vs low: ß = -0.30, 95% CI -0.48 to -0.12; and high increasing vs low: ß = -0.49, 95% CI -0.70 to -0.27; DSST persistently medium vs low: ß = -0.28, 95% CI -0.47 to -0.09; and high increasing vs low: ß = -0.64, 95% CI -0.87 to -0.42; Stroop persistently medium vs low: ß = -0.46, 95% CI -0.70 to -0.23; and high increasing vs low: ß = -0.76, 95% CI -1.04 to -0.47). Associations were slightly weaker among White individuals, but we still found that having 'high increasing' depressive symptoms was associated with worse verbal memory and processing speed scores (high increasing vs low: ß = -0.38, 95% CI -0.61 to -0.15; and ß = -0.40, 95% CI -0.63 to -0.18, respectively). DISCUSSION: Prolonged exposure to elevated depressive symptoms beginning in young adulthood may result in worse cognitive function over midlife. This association was stronger among Black adults.
