Background: Despite having higher exposure to stressors, many ethno-racial groups report similar or lower prevalence of clinical depression and anxiety compared to their White counterparts, despite experiencing greater psychosocial risk factors for poor mental health outcomes, thus presenting an epidemiological paradox. Ethno-racial differences in impairment, a diagnostic criterion, may in part explain this paradox. Methods: We analyzed data from the Healthy Minds Study (2020-2021) and using survey-weighted linear mixed effects models, we tested whether there were ethno-racial differences in impairment across multiple ethno-racial groups at various levels of severity for anxiety and depression. Results: Black students reported lower mean impairment scores relative to White students at moderate and severe anxiety. Hispanic/Latine students only reported lower impairment relative to White students at severe anxiety. Asian students reported relatively lower mean impairment than White students at mild anxiety, and this difference continued to grow as anxiety severity increased. Similar trends were observed for depression. Black and Hispanic/Latino students reported lower mean impairment scores at moderate to severe depression. Asian students reported lower mean impairment scores beginning at mild depression to severe depression. Conclusion: Self-reported anxiety and depression related impairment varies by ethno-racial group, with Black, Hispanic/Latinx, and Asian students reporting lower impairment compared to White students at higher levels of symptom severity. These findings open the possibility that racial differences in the impairment criterion of clinical diagnoses may explain some of the racial paradox.

BACKGROUND: There are no guidelines on when to more strongly recommend sentinel lymph node biopsy (SLNB) for T1b melanomas. OBJECTIVE: To examine whether anatomic locations of T1b melanomas and patient age influence metastases. METHODS: We conducted a retrospective study using data from two hospitals in Los Angeles County from January 2010 through January 2020. RESULTS: Out of 620 patients with primary melanomas, 566 melanomas were staged based on the American Joint Committee on Cancer 8th edition melanoma staging. Forty-one were T1b, of which 13 were located on the face/ear/scalp and 28 were located elsewhere. T1b melanomas located on the face/ear/scalp had an increased risk of lymph node or distant metastasis compared with other anatomic sites (31% vs 3.6%, P=0.028). For all melanomas, the risk of lymph node or distant metastasis decreased with age of 64 years or greater (P<0.001 and P=0.034). For T1b melanomas, the risk of distant metastasis increased with increasing age (P=0.047). LIMITATIONS: Data were from a single county.  Conclusion: T1b melanomas of the face/ear/scalp demonstrated a higher risk of lymph node or distant metastasis and may help guide the recommendation of SLNB, imaging, and surveillance. Younger patients may be more strongly considered for SLNB and older patients with T1b melanomas may warrant imaging.  J Drugs Dermatol. 2024;23(5):306-310. doi:10.36849/JDD.7667.

OBJECTIVE: Comprehensive studies examining longitudinal predictors of dietary change during the coronavirus disease 2019 pandemic are lacking. Based on an ecological framework, this study used longitudinal data to test if individual, social and environmental factors predicted change in dietary intake during the peak of the coronavirus 2019 pandemic in Los Angeles County and examined interactions among the multilevel predictors. DESIGN: We analysed two survey waves (e.g. baseline and follow-up) of the Understanding America Study, administered online to the same participants 3 months apart. The surveys assessed dietary intake and individual, social, and neighbourhood factors potentially associated with diet. Lagged multilevel regression models were used to predict change from baseline to follow-up in daily servings of fruits, vegetables and sugar-sweetened beverages. SETTING: Data were collected in October 2020 and January 2021, during the peak of the coronavirus disease 2019 pandemic in Los Angeles County. PARTICIPANTS: 903 adults representative of Los Angeles County households. RESULTS: Individuals who had depression and less education or who identified as non-Hispanic Black or Hispanic reported unhealthy dietary changes over the study period. Individuals with smaller social networks, especially low-income individuals with smaller networks, also reported unhealthy dietary changes. After accounting for individual and social factors, neighbourhood factors were generally not associated with dietary change. CONCLUSIONS: Given poor diets are a leading cause of death in the USA, addressing ecological risk factors that put some segments of the community at risk for unhealthy dietary changes during a crisis should be a priority for health interventions and policy.

BACKGROUND: Discrimination is associated with worse mental and physical health outcomes. However, the associations among cancer survivors are limited. OBJECTIVE: We examined whether discrimination is associated with HRQoL and whether adjusting for it reduces racial/ethnic disparities in HRQoL among cancer survivors. METHODS: Cross-sectional data from adult cancer survivors who completed surveys on discrimination in the medical settings (DMS), everyday perceived discrimination (PD), and HRQoL in the "All of Us" Program from 2018 to 2022 were assessed. We created a binary indicator for fair-to-poor vs. good-to-excellent physical health and mental health. PD and DMS scores were a continuous measure with higher scores reflecting more discrimination. Multivariable logistic regression models tested whether DMS and PD are associated with HRQoL and whether they differently affect the association between race/ethnicity and HRQoL. RESULTS: The sample (N = 16,664) of cancer survivors was predominantly White (86%) and female (59%), with a median age of 69. Every 5-unit increase in DMS and PD scores was associated with greater odds of fair-to-poor physical health (DMS: OR [95%CI] = 1.66 [1.55, 1.77], PD: 1.33 [1.27, 1.40]) and mental health (DMS: 1.57 [1.47, 1.69], PD: 1.33 [1.27, 1.39]). After adjusting for DMS or PD, Black and Hispanic survivors had a decreased likelihood of fair-to-poor physical health and mental health (decrease estimate range: - 6 to - 30%) compared to White survivors. This effect was greater for Black survivors when adjusting for PD, as the odds of fair-to-poor mental health compared to White survivors were no longer statistically significant (1.78 [1.32, 2.34] vs 1.22 [0.90, 1.64]). CONCLUSION: Experiences of discrimination are associated with lower HRQoL and reducing it may mitigate racial/ethnic disparities in HRQoL.

INTRODUCTION: Patients with classical congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency exhibit an increased prevalence of obesity from childhood including central adiposity and inflammation. There is also an emerging affected brain phenotype in CAH, with decreased cortico-limbic gray matter volumes and white matter abnormalities. We aimed to study the relationship between brain structure, obesity, and inflammation in children and adolescents with CAH compared to controls. METHODS: 27 CAH (12.6±3.4y, 16 females) and 35 controls (13.0±2.8y, 20 females) had MRI of gray matter regions of interest [prefrontal cortex (PFC), amygdala, hippocampus] and white matter microstructure [fornix, stria terminalis (ST)]. Anthropometric measures and lab analytes were obtained. Relaimpo analyses (relative importance for linear regression; percent variance) identified which brain structures were most different between groups. Subsequent regressions further quantified the magnitude and direction of these relationships. Correlations analyzed relationships between brain structure, obesity, and inflammation in the context of CAH status. RESULTS: PFC (13.3% variance) and its superior frontal (SF) subregion (14%) were most different between CAH and controls for gray matter; ST (16%) for white matter. Patients with CAH had lower caudal middle frontal [ß = -0.56, (-0.96, -0.15)] and superior frontal [ß = -0.58 (-0.92, -0.25)] subregion volumes, increased orientation dispersion index in the fornix [ß = 0.56 (0.01, 1.10)] and ST [ß = 0.85 (0.34, 1.36)], and decreased fractional anisotropy in the fornix [ß = -0.91 (-1.42, -0.42)] and ST [ß = -0.83 (-1.34, -0.33)] (all p's <0.05) indicating axonal disorganization, reduced myelin content, and/or higher microglial density within the affected white matter tracts. For the full cohort, SF was correlated with MCP-1 (r=-0.41), visceral adipose tissue (r=-0.25), and waist-to-height ratio (r=-0.27, all p's <0.05); ST was correlated with MCP-1 (r=0.31) and TNF-α (r= 0.29, all p's <0.05); however, after adjusting for CAH status, almost all correlations were attenuated for significance. CONCLUSIONS: Relationships among key brain structures, body composition and inflammatory markers in pediatric patients with CAH could be largely driven by having CAH, with implications for obesity and neuroinflammation in this high-risk population.

INTRODUCTION: Heterotopic ossification (HO), or ectopic bone formation in soft tissue, is a not so rare and poorly understood debilitating sequela of burn injury. Individuals developing HO following burn injuries to their hands often experience reductions in mobility, significant contractures, and joint pain. This study identifies demographic characteristics of individuals who develop HO and compares their physical and psychosocial outcomes to the general burn population. METHODS: Participant demographics, injury characteristics, and PROMIS-29 scores across three time points (discharge, six- and 12- months after injury) were extracted from the Burn Model System National Longitudinal Database representing participants from 2015-2022. Mixed-effects linear regression models were used to compare PROMIS scores across all three longitudinal measurements. Models were adjusted for age, sex, race/ethnicity, HO status, and burn size. RESULTS: Of the 861 participants with data concerning HO, 33 were diagnosed with HO (3.8% of participants). Most participants with HO were male (n = 24, 73%) and had an average age of 40 + /- 13 years. Participants with HO had significantly larger burn size (49 +/-23% Total Body Surface Area (TBSA)) than those without HO (16 +/-17%). Participants with HO reported significantly worse physical function, depression, pain interference and social integration scores than those without HO. After adjusting for covariables, participants with HO continued to report statistically significantly worse physical function than those without HO. Although physical functioning was consistently lower, the two populations did not differ significantly among psychosocial outcome measures. CONCLUSIONS: While HO can result in physical limitations, the translation to psychosocial impairments was not evident. Targeted treatment of HO with the goal of maximizing physical function should be a focus of their rehabilitation. LEVEL OF EVIDENCE: 2b TYPE OF STUDY: Symptom Prevalence Study.

ABSTRACT: Estimated fetal weight (EFW) is frequently used for clinical decision-making in obstetrics. The goals of this study were to determine the accuracy of EFW assessments by Leopold and ultrasound and to investigate any associations with maternal characteristics. Postgraduate years 1 and 2 obstetrics and gynecology resident physicians from Harbor-UCLA Medical Center from 2014 to 2020 performed EFW assessments on 10 preterm (<37 weeks' gestational age) fetuses by ultrasound biometry and 10 full-term (≥37 weeks' gestational age) fetuses by ultrasound biometry and Leopold maneuver. Assessments were included if the patients delivered within 2 weeks of the assessments. One thousand six hundred ninety-seven EFW assessments on 1183 patients performed by 33 residents were analyzed; 72.6% of sonographic full-term EFWs, 69% of Leopold full-term EFWs, and 61.5% of sonographic preterm EFWs were within 10% of the neonatal birth weight (BW). The lowest estimation error in our study occurred when actual BW was 3600 to 3700 g. After adjusting for BW, residents were found to have lower accuracy when the mother had a higher body mass index (BMI) for full-term estimation methods (Leopold and ultrasound, ß = 0.13 and 0.12, P = 0.001 and 0.002, respectively). Maternal BMI was not related to estimation error for preterm fetuses ( ß = 0.01, P = 0.75). Clinical and sonographic EFW assessments performed by obstetrics and gynecology junior residents are within 10% of neonatal BW much of the time. In our cohort, they tended to overestimate EFWs of lower-BW infants and underestimate EFWs of higher-BW infants. Accuracy of full-term EFW assessments seems to decrease with increasing maternal BMI.

PURPOSE: We determined whether racial/ethnic differences in patient experiences with care influence timeliness and type of initial surgical breast cancer treatment for a sample of female Medicare cancer patients. METHODS: We conducted a retrospective cohort study using the linked Epidemiology and End Results-Consumer Assessment of Healthcare Providers and Systems (SEER-CAHPS) dataset. The outcomes were: (1) time-to-initial surgical treatment, and (2) type of treatment [breast conserving surgery (BCS) vs. mastectomy]. The indicators were reports of four types of patient experiences with care including doctor communication, getting care quickly, getting needed care, and getting needed Rx. Interaction terms in each multivariable logistic model examined if the associations varied by race/ethnicity. RESULTS: Of the 2069 patients, 84.6% were White, 7.6% Black and 7.8% Hispanic. After adjusting for potential confounders, non-Hispanic Black patients who provided excellent reports of their ability to get needed prescriptions had lower odds of receiving surgery within 2-months of diagnosis, compared to NH-Whites who provided less than excellent reports (aOR: 0.29, 95% CI 0.09-0.98). There were no differences based on 1-month or 3-month thresholds. We found no other statistically significant effect of race/ethnicity. As to type of surgery, among NH Blacks, excellent reports of getting care quickly were associated with higher odds of receiving BCS versus mastectomy (aOR: 2.82, 95% CI 1.16-6.85) compared to NH Whites with less than excellent reports. We found no other statistically significant differences by race/ethnicity. CONCLUSION: Experiences with care are measurable and modifiable factors that can be used to assess and improve aspects of patient-centered care. Improvements in patient care experiences of older adults with cancer, particularly among minorities, may help to eliminate racial/ethnic disparities in timeliness and type of surgical treatment.

OBJECTIVE: The aim of this study was to investigate the mediating role of child brain structure in the relationship between prenatal gestational diabetes mellitus (GDM) exposure and child adiposity. METHODS: This was a cross-sectional study of 9- to 10-year-old participants and siblings across the US. Data were obtained from the baseline assessment of the Adolescent Brain Cognitive Development (ABCD) Study®. Brain structure was evaluated by magnetic resonance imaging. GDM exposure was self-reported, and discordance for GDM exposure within biological siblings was identified. Mixed effects and mediation models were used to examine associations among prenatal GDM exposure, brain structure, and adiposity markers with sociodemographic covariates. RESULTS: The sample included 8521 children (7% GDM-exposed), among whom there were 28 sibling pairs discordant for GDM exposure. Across the entire study sample, prenatal exposure to GDM was associated with lower global and regional cortical gray matter volume (GMV) in the bilateral rostral middle frontal gyrus and superior temporal gyrus. GDM-exposed siblings also demonstrated lower global cortical GMV than unexposed siblings. Global cortical GMV partially mediated the associations between prenatal GDM exposure and child adiposity markers. CONCLUSIONS: The results identify brain markers of prenatal GDM exposure and suggest that low cortical GMV may explain increased obesity risk for offspring prenatally exposed to GDM.

Pediatric obesity and cardiometabolic disease disproportionately impact minority communities. Sugar reduction is a promising prevention strategy with consistent cross-sectional associations of increased sugar consumption with unfavorable biomarkers of cardiometabolic disease. Few trials have tested the efficacy of pediatric sugar reduction interventions. Therefore, in a parallel-design trial, we randomized Latino youth with obesity (BMI ≥ 95th percentile) [n = 105; 14.8 years] to control (standard diet advice) or sugar reduction (clinical intervention with a goal of ≤10% of calories from free sugar) for 12-weeks. Outcomes included changes in glucose tolerance and its determinants as assessed by a 2-h frequently sample oral glucose tolerance test, fasting serum lipid profile (total cholesterol, HDL, LDL, triglycerides, cholesterol:HDL), and inflammatory markers (CRP, IL-6, TNF-α). Free sugar intake decreased in the intervention group compared to the control group [11.5% to 7.3% vs. 13.9% to 10.7% (% Energy), respectively, p = 0.02], but there were no effects on any outcome of interest (pall > 0.07). However, an exploratory analysis revealed that sugar reduction, independent of randomization, was associated with an improved Oral-disposition index (p < 0.001), triglycerides (p = 0.049), and TNF-α (p = 0.02). Dietary sugar reduction may have the potential to reduce chronic disease risks through improvements in beta-cell function, serum triglycerides, and inflammatory markers in Latino adolescents with obesity.

BACKGROUND: The objective of this study was to determine whether racial/ethnic disparities exist in patient-reported experiences with care after colorectal cancer diagnosis and whether they are associated with mortality. METHODS: We conducted a retrospective cohort study of colorectal cancer patients diagnosed from 1997 to 2011, ≥ 65 years, and completed a Consumer Assessment of Healthcare Providers and Systems (CAHPS) survey at least 6 months after a cancer diagnosis. We leverage the National Cancer Institute's SEER-CAHPS dataset of Medicare beneficiaries. CAHPS survey responses were used to generate four composite measures of patient experiences with 1) getting needed care, 2) getting needed prescription drugs, 3) getting care quickly, and 4) physician communication. We used multivariable linear regression models to examine racial differences in patient experiences with aspects of their care and multivariable Cox proportional hazards models to identify the risk of mortality associated with each composite score by racial group. RESULTS: Of the 5135 patients, 76.86% were non-Hispanic White, 7.58% non-Hispanic Black, 8.30% Hispanic, and 7.26% non-Hispanic Asian. Overall, patients reported the highest scores for composite measures regarding "getting all needed prescriptions" and the lowest score for "getting care quickly." In our adjusted models, we found that Hispanics, non-Hispanic Black, and non-Hispanic Asian patients reported significantly lower scores for getting needed prescription drugs (B = - 4.34, B = - 4.32, B = - 5.66; all p < 0.001) compared to non-Hispanic Whites. Moreover, non-Hispanic Black patients also reported lower scores for getting care quickly (B = - 3.44, p < 0.05). We only found one statistically significant association between composite scores of patient experience and mortality. For non-Hispanic Black patients, a 3-unit increase in getting needed care was associated with 0.97 times the hazard of mortality (p = 0.003). CONCLUSION: Our research underscores that CAHPS patient experiences with care are an important patient-centered quality-of-care metric that may be associated with cancer outcomes and that there may be differences in these relationships by race and ethnicity. Thus, highlighting how patients' perceptions of their healthcare experiences can contribute to disparities in colorectal cancer outcomes.

AIM: To synthesize epidemiologic literature pertaining to the association between preeclampsia (PE), attention-deficit/hyperactivity disorder (ADHD), autism spectrum disorder (ASD), and epilepsy. METHOD: A systematic search of PubMed and Embase was performed supplemented by hand-searching of reference lists of eligible studies. Two independent reviewers screened abstracts following a prepared protocol. Data extraction and quality appraisal using the Newcastle Ottawa Scale were performed by an independent reviewer. PRISMA guidelines were followed throughout. Random-effects meta-analyses were performed. Adjusted pooled Odds Ratios and their 95% confidence intervals were reported. RESULTS: Fifteen out of 121 identified studies were eligible for inclusion. Six reported adjusted estimates for ADHD, resulting in a pooled odds ratio of 1.29 (95% CI: 1.20, 1.38). Eight reported adjusted estimates for ASD, resulting in a pooled odds ratio of 1.27 (95% CI:1.22, 1.32). Three reported adjusted estimates for epilepsy, resulting in a pooled odds ratio of 1.35 (95% CI: 1.12, 1.63). INTERPRETATION: Intrauterine exposure to PE increased the risk of ADHD, ASD, and epilepsy, though it is unclear whether the true association is with pre-term birth. To our knowledge, this is the first meta-analysis to quantify the association between PE and epilepsy. The results of this meta-analysis can inform screening strategies among children born to preeclamptic mothers for early identification and treatment.

PURPOSE: Current decision-making in multilevel cervical fusion weighs the potential to protect adjacent levels and reduce reoperation risk by crossing the cervicothoracic junction (C7/T1) against increased operative time and risk of complication. Careful planning is required, and the planned distal and adjacent levels should be assessed for degenerative disc disease (DDD). This study assessed whether DDD at the cervicothoracic junction was associated with DDD, disc height, translational motion, or angular variation in the adjacent superior (C6/C7) or inferior (T1/T2) levels. METHODS: This study retrospectively analyzed 93 cases with kinematic MRI. Cases were randomly selected from a database with inclusion criteria being no prior spine surgery and images having sufficient quality for analysis. DDD was assessed using Pfirrmann classification. Vertebral body bone marrow lesions were assessed using Modic changes. Disc height was measured at the mid-disc in neutral and extension. Translational motion and angular variation were calculated by assessing translational or angular motion segment integrity respectively in flexion and extension. Statistical associations were assessed with scatterplots and Kendall's tau. RESULTS: DDD at C7/T1 was positively associated with DDD at C6/C7 (tau = 0.53, p < 0.01) and T1/T2 (tau = 0.58, p < 0.01), with greater disc height in neutral position at T1/T2 (tau = 0.22, p < 0.01), and with greater disc height in extended position at C7/T1 (tau = 0.17, p = 0.04) and at T1/T2 (tau = 0.21, p < 0.01). DDD at C7/T1 was negatively associated with angular variation at C6/C7 (tau = - 0.23, p < 0.01). No association was appreciated between DDD at C7/T1 and translational motion. CONCLUSION: The association of DDD at the cervicothoracic junction with DDD at the adjacent levels emphasizes the necessity for careful selection of the distal level in multilevel fusion in the distal cervical spine.

Introduction: COVID-19 vaccine inequities have been widespread across California, the United States, and globally. As COVID-19 vaccine inequities have not been fully understood in the youth population, it is vital to determine possible factors that drive inequities to enable actionable change that promotes vaccine equity among vulnerable minor populations. Methods: The present study used the social vulnerability index (SVI) and daily vaccination numbers within the age groups of 12-17, 5-11, and under 5 years old across all 58 California counties to model the growth velocity and the anticipated maximum proportion of population vaccinated. Results: Overall, highly vulnerable counties, when compared to low and moderately vulnerable counties, experienced a lower vaccination rate in the 12-17 and 5-11 year-old age groups. For age groups 5-11 and under 5 years old, highly vulnerable counties are expected to achieve a lower overall total proportion of residents vaccinated. In highly vulnerable counties in terms of socioeconomic status and household composition and disability, the 12-17 and 5-11 year-old age groups experienced lower vaccination rates. Additionally, in the 12-17 age group, high vulnerability counties are expected to achieve a higher proportion of residents vaccinated compared to less vulnerable counterparts. Discussion: These findings elucidate shortcomings in vaccine uptake in certain pediatric populations across California and may help guide health policies and future allocation of vaccines, with special emphasis placed on vulnerable populations, especially with respect to socioeconomic status and household composition and disability.

INTRODUCTION: Patients with classical congenital adrenal hyperplasia (CAH) have prenatal and postnatal hormonal imbalances. To characterize the ontogeny of reported brain and behavior changes in older children with CAH, we aimed to study the brain structure in infants with CAH compared to healthy controls. METHODS: We performed neuroimaging in 16 infants with classical CAH due to 21-hydroxylase deficiency (8 males, gestational age 38.2 ± 1.7 weeks, post-conceptional age [PCA] 42.2 ± 3.0 weeks) and 14 control infants (9 males, gestational age 38.5 ± 1.8 weeks, PCA 42.5 ± 2.4 weeks) utilizing 3-Tesla magnetic resonance imaging. Regional brain volumes were adjusted for PCA and sex, along with an additional adjustment for total brain volume (TBV), for group comparisons by regression analyses (mean, 95% confidence interval [CI]). The degree to which each brain region was differentiated between CAH and control infants was examined by relaimpo analyses, adjusting for all other brain regions, PCA, and sex. RESULTS: Infants with CAH had significantly smaller thalamic volumes (8,606 mm3, 95% CI [8,209, 9,002]) compared to age-matched control infants (9,215 mm3, 95% CI [8,783, 9,647]; ß = -609; p = 0.02) which remained smaller after further adjustment for TBV. Upon further adjustment for TBV, the temporal lobe was larger in infants with CAH (66,817 mm3, CI [65,957, 67,677]) compared to controls (65,616 mm3, CI [64,680, 66,551]; ß = 1,202, p = 0.03). The brain regions most differentiated between CAH versus controls were the thalamus (22%) and parietal lobe (10%). CONCLUSIONS: Infants with CAH exhibit smaller thalamic regions from early life, suggesting a prenatal influence on brain development in CAH. Thalamic emergence at 8-14 weeks makes the region particularly vulnerable to changes in the intrauterine environment, with potential implications for later maturing brain regions. These changes may take time to manifest, meriting longitudinal study through adolescence in CAH.

PURPOSE: We examined whether breast cancer survivors' experiences with care differed by a recent history of clinical depression, and whether associations differed by race/ethnicity. METHODS: Using the Epidemiology and End Results-Consumer Assessment of Healthcare Providers and Systems (SEER-CAHPS) dataset, we analyzed records of breast cancer survivors who completed a survey at least 12 months after their cancer diagnosis. We assessed clinical depression 12 months prior to survey completion using Medicare claims. We used separate multivariable logistic regressions to examine the associations between depression and excellent (vs. less than excellent) ratings of experiences with care (i.e., doctor communication, getting needed care, getting care quickly, getting prescription drugs, specialist and overall care). We also assessed interactions of depression by race/ethnicity. All models were adjusted for demographics and cancer prognostic and treatment factors. RESULTS: Of the 2271 survivors, 7.6% were clinically depressed. After adjusting for covariates, survivors with clinical depression had lower odds of reporting excellent ratings of their ability to get needed care, care by their specialist, and overall care, compared to those without depression (AOR = 0.58, 95% CI: 0.40-0.84; AOR = 0.40, CI: 0.31-0.76; and AOR = 0.61, CI: 0.42-0.89, respectively). Among Hispanics, having depression was associated with higher odds of excellent ratings of one's ability to get needed care (AOR: 5.42, 95% CI: 1.02-28.81). No other statistically significant associations by race/ethnicity were found. CONCLUSIONS: Breast cancer survivors with depression report poorer patient experiences with care. Further research is needed to understand complexities of ratings of experiences with care among survivors of diverse backgrounds. IMPLICATIONS: Survivors with a recent history of clinical depression may benefit from additional supportive care services.

Background: Infants at risk for developmental disabilities often show signs of motor delay. Reaching is a skill that can help us identify atypical motor trajectories in early infancy. Researchers have studied performance after onset of reaching, but none have followed infants at risk from pre-reaching to skilled reaching. Aims: We assessed differences in reaching outcomes and hand use as reaching skill emerged in infants at risk for developmental disabilities and with typical development. Methods and Procedures: We followed infants at risk for developmental disabilities (n = 11) and infants with typical development (n = 21) longitudinally as they developed reaching skill. Infants reached for a toy at midline while sitting in the caregiver's lap. Video data were coded for reach outcome (miss, touch, partial grasp, and whole-hand grasp) and hand use (right, left, and bilateral). Outcomes and Results: Infants at risk had a larger proportion of missed reaches across visits compared to infants with typical development. Infants at risk also showed less variability in hand use when grasping over the study period. Conclusion and Implications: Our results provide information to support early differences in reaching performance to inform identification of typical and atypical developmental trajectories. Future studies should assess how the missed reaches are different and consider other quantitative measures of movement variability in infants at risk.

OBJECTIVE: This study examined associations between BMI and dietary sugar intake with sucrose-induced fibroblast growth factor 21 (FGF21) and whether circulating FGF21 is associated with brain signaling following sucrose ingestion in humans. METHODS: A total of 68 adults (29 male; mean [SD), age 23.2 [3.8] years; BMI 27.1 [4.9] kg/m2 ) attended visits after a 12-hour fast. Plasma FGF21 was measured at baseline and at 15, 30, and 120 minutes after sucrose ingestion (75 g in 300 mL of water). Brain cerebral blood flow responses to sucrose were measured using arterial spin labeling magnetic resonance imaging. RESULTS: Higher circulating FGF21 levels were associated with reduced blood flow in the striatum in response to sucrose (ß = -7.63, p = 0.03). This association was greatest among persons with healthy weight (ß = -15.70, p = 0.007) and was attenuated in people with overweight (ß = -4.00, p = 0.63) and obesity (ß = -12.45, p = 0.13). BMI was positively associated with FGF21 levels in response to sucrose (ß = 0.53, p = 0.02). High versus low dietary sugar intake was associated with greater FGF21 responses to acute sucrose ingestion in individuals with healthy weight (ß = 8.51, p = 0.04) but not in individuals with overweight or obesity (p > 0.05). CONCLUSIONS: These correlative findings support evidence in animals showing that FGF21 acts on the brain to regulate sugar consumption through a negative feedback loop.

BACKGROUND: Peer-led interventions for adolescents are effective at accelerating behavioral change. The Sources of Strength suicide preventive program trains student peer change agents (peer leaders) in secondary schools to deliver prevention messaging and conduct activities that increase mental health coping mechanisms. The program currently has school staff select peer leaders. This study examined potential for more efficient program diffusion if peer leaders had been chosen under network-informed selection methods. METHODS: Baseline assessments were collected from 5,746 students at 20 schools. Of these, 429 were selected by adults as peer leaders who delivered intervention content through the school year. We created theoretical alternate peer leader sets based on social network characteristics: opinion leadership, centrality metrics, and key players. Because these sets were theoretical, we examined the concordance of these sets with the actual adult-selected peer leaders sets and correlated this metric with diffusion of intervention modalities (i.e., presentation, media, communication, activity) after the first year. RESULTS: The sets of adult-selected peer leaders were 13.3%-22.7% similar to theoretical sets chosen by other sociometric methods. The use of friendship network metrics produced peer leader sets that were more white and younger than the general student population; the Key Players method produced more representative peer leader sets. Peer opinion leaders were older and more white than the general population. Schools whose selected peer leaders had higher overlap with theoretical ones had greater diffusion of intervention media and peer communication. CONCLUSIONS: The use of network information in school-based peer-led interventions can help create more systematized peer leader selection processes. To reach at-risk students, delivery of an indirect message, such as through a poster or video, may be required. A hybrid approach where a combination of visible, respected opinion leaders, along with strategically-placed key players within the network, may provide the greatest potential for intervention diffusion.
