Ethno-racial differences in anxiety and depression impairment among emerging adults in higher education. SSM Popul Health 2024; 26:101678. [PMID: 38737143 PMCID: PMC11081800 DOI: 10.1016/j.ssmph.2024.101678] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/29/2023] [Revised: 03/05/2024] [Accepted: 04/25/2024] [Indexed: 05/14/2024] Open
Abstract
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.

The impact of enhanced recovery after surgery (ERAS) on opioid consumption and postoperative pain levels in elective spine surgery. Clin Neurol Neurosurg 2024; 242:108350. [PMID: 38788543 DOI: 10.1016/j.clineuro.2024.108350] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/27/2024] [Revised: 05/17/2024] [Accepted: 05/21/2024] [Indexed: 05/26/2024]
Abstract
OBJECTIVE Enhanced Recovery after Surgery (ERAS) protocols were developed to counteract the adverse effects of the surgical stress response, aiming for quicker postoperative recovery. Initially applied in abdominal surgeries, ERAS principles have extended to orthopedic spine surgery, but research in this area is still in its infancy. The current study investigated the impact of ERAS on postoperative pain and opioid consumption in elective spine surgeries. METHODS A single-center retrospective study of patients undergoing elective spine surgery from May 2019 to July 2020. Patients were categorized into two groups: those enrolled in the ERAS pathway and those adhering to traditional surgical protocols. Data on demographics, comorbidities, length of stay (LOS), surgical procedures, and postoperative outcomes were collected. Postoperative pain was evaluated using the Numerical Rating Scale (NRS), while opioid utilization was quantified in morphine milligram equivalents (MME). NRS and MME were averaged for each patient across all days under observation. Differences in outcomes between groups (ERAS vs. treatment as usual) were tested using the Wilcoxon rank sum test for continuous variables and Pearson's or Fisher's exact tests for categorical variables. RESULTS The median of patient's mean daily NRS scores for postoperative pain were not statistically significantly different between groups (median = 5.55 (ERAS) and 5.28 (non-ERAS), p=.2). Additionally, the median of patients' mean daily levels of MME were similar between groups (median = 17.24 (ERAS) and 16.44 (non-ERAS), p=.3) ERAS patients experienced notably shorter LOS (median=2 days) than their non-ERAS counterparts (median=3 days, p=.001). The effect of ERAS was moderated by whether the patient had ACDF surgery. ERAS (vs. non-ERAS) patients who had ACDF surgery had 1.64 lower average NRS (p=.006). ERAS (vs. non-ERAS) patients who had a different surgery had 0.72 higher average NRS (p=.02) but had almost half the length of stay, on average (p<.001). CONCLUSIONS The current study underscores the dynamic nature of ERAS protocols within the realm of spine surgery. While ERAS demonstrates advantages such as reduced LOS and improved patient-reported outcomes, it requires careful implementation and customization to address the specific demands of each surgical discipline. The potential to expedite recovery, optimize resource utilization, and enhance patient satisfaction cannot be overstated. However, the fine balance between achieving these benefits and ensuring comprehensive patient care, especially in the context of postoperative pain management, must be maintained. As ERAS continues to evolve and find its place in diverse surgical domains, it is crucial for healthcare providers to remain attentive to patient needs, adapting ERAS protocols to suit individual patient populations and surgical contexts.

Abstract
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.

Abstract
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.

Physical and psychosocial outcomes among burn-injured people with heterotopic ossification: A burn model system study. Burns 2024; 50:957-965. [PMID: 38267289 PMCID: PMC11055684 DOI: 10.1016/j.burns.2024.01.017] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/07/2023] [Revised: 01/10/2024] [Accepted: 01/15/2024] [Indexed: 01/26/2024]
Abstract
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.

Racial/Ethnic Disparities: Discrimination's Impact on Health-Related Quality of Life-An All of Us Cancer Survivors' Cross-sectional Study. J Racial Ethn Health Disparities 2024:10.1007/s40615-024-02006-z. [PMID: 38653897 DOI: 10.1007/s40615-024-02006-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/02/2024] [Revised: 04/11/2024] [Accepted: 04/14/2024] [Indexed: 04/25/2024]
Abstract
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.

Abstract
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, β = 0.13 and 0.12, P = 0.001 and 0.002, respectively). Maternal BMI was not related to estimation error for preterm fetuses ( β = 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.

Abstract
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 [β = -0.56, (-0.96, -0.15)] and superior frontal [β = -0.58 (-0.92, -0.25)] subregion volumes, increased orientation dispersion index in the fornix [β = 0.56 (0.01, 1.10)] and ST [β = 0.85 (0.34, 1.36)], and decreased fractional anisotropy in the fornix [β = -0.91 (-1.42, -0.42)] and ST [β = -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.

Abstract
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.

Abstract
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.

Abstract
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.

Effects of Dietary Sugar Reduction on Biomarkers of Cardiometabolic Health in Latino Youth: Secondary Analyses from a Randomized Controlled Trial. Nutrients 2023; 15:3338.

Abstract
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.

What does degeneration at the cervicothoracic junction tell us? A kinematic MRI study of 93 individuals. EUROPEAN SPINE JOURNAL : OFFICIAL PUBLICATION OF THE EUROPEAN SPINE SOCIETY, THE EUROPEAN SPINAL DEFORMITY SOCIETY, AND THE EUROPEAN SECTION OF THE CERVICAL SPINE RESEARCH SOCIETY 2023; 32:2425-2430.

Abstract
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.

Healthcare Experiences Are Associated with Colorectal Cancer Mortality but only for Specific Racial Groups: a SEER-CAHPS Study. J Racial Ethn Health Disparities 2023:10.1007/s40615-023-01690-7. [PMID: 37369914 DOI: 10.1007/s40615-023-01690-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/22/2023] [Revised: 06/01/2023] [Accepted: 06/18/2023] [Indexed: 06/29/2023]
Abstract
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.

COVID-19 vaccination dynamics in the US: coverage velocity and carrying capacity based on socio-demographic vulnerability indices in California's pediatric population. Front Public Health 2023; 11:1148200. [PMID: 37228717 PMCID: PMC10203576 DOI: 10.3389/fpubh.2023.1148200] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/19/2023] [Accepted: 04/03/2023] [Indexed: 05/27/2023] Open
Abstract
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.

Abstract
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]; β = -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]; β = 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.

Do breast cancer survivors with a recent history of clinical depression report worse experiences with care? A retrospective cohort study using SEER-CAHPS data. Cancer Med 2022; 12:1949-1960. [PMID: 35929584 PMCID: PMC9883547 DOI: 10.1002/cam4.5031] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/14/2022] [Revised: 05/26/2022] [Accepted: 06/29/2022] [Indexed: 02/02/2023] Open
Abstract
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.

Abstract
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.

FGF21 response to sucrose is associated with BMI and dorsal striatal signaling in humans. Obesity (Silver Spring) 2022; 30:1239-1247. [PMID: 35491674 DOI: 10.1002/oby.23432] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/07/2022] [Revised: 02/24/2022] [Accepted: 02/28/2022] [Indexed: 12/30/2022]
Abstract
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 (β = -7.63, p = 0.03). This association was greatest among persons with healthy weight (β = -15.70, p = 0.007) and was attenuated in people with overweight (β = -4.00, p = 0.63) and obesity (β = -12.45, p = 0.13). BMI was positively associated with FGF21 levels in response to sucrose (β = 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 (β = 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.

A comparison of peer change agent selection methods: Evidence from a high-school based suicide preventive intervention. BMC Public Health 2022; 22:985.

Abstract
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.

Evaluation of a breastfeeding promotion film among a racially minoritized sample. BMC Pregnancy Childbirth 2022; 22:262. [PMID: 35346106 PMCID: PMC8962205 DOI: 10.1186/s12884-022-04607-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/27/2021] [Accepted: 03/22/2022] [Indexed: 11/10/2022] Open
Abstract
Abstract
Background
In Los Angeles County (LAC), disparities in breastfeeding rates vary by race and region. Black persons are more affected by social and environmental factors than other racial/ethnic groups, leading to lower breast/chestfeeding rates. This study aims to evaluate the community’s knowledge, perceptions, experiences, barriers, and solutions before and after an educational film about Black persons who are breast/chestfeeding.
Methods
Participant responses were collected anonymously through an online survey (via QR code) pre-and post-viewing a film with open- and closed-ended questions. There were 15 pre-screening questions and 24 post-screening questions discussed with a team of community experts. Questions included four main areas related to breast/chestfeeding: current/past experiences, support, awareness of laws, and solutions. Central tendency, variance, and paired differences were calculated from evaluation responses.
Results
There were 185 participants who completed the pre-screening evaluation and 57 participants who completed the post-screening evaluation. Racial/ethnic differences were found for stated reasons for attendance, and perceptions of breastfeeding being challenging after viewing the video. On a five-point Likert scale (1 = very relevant, 5 = not relevant), most participants felt the video was relevant (median response = “2-relevant”; IQR = “3-neutral”; “1-very relevant”), learned something new (81.4%) and knew how to access breast/chestfeeding support after viewing the video (93.2%).
Conclusions
Current media is a way to alter perceptions and opinions, and provides information. Additionally, it can be a way of increasing awareness of issues that Black breast/chestfeeding persons encounter. Strategic marketing efforts for future film screenings may increase attendance of those that can gain insight into breast/chestfeeding support (youth/young adults and males). Supportive breast/chestfeeding environments can also be a reality with readily accessible, unified, and encouraging personal and professional networks.

Clinical Intervention to Reduce Dietary Sugar Does Not Affect Liver Fat in Latino Youth, Regardless of PNPLA3 Genotype: A Randomized Controlled Trial. J Nutr 2022; 152:1655-1665. [PMID: 35218194 PMCID: PMC9258557 DOI: 10.1093/jn/nxac046] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/04/2021] [Revised: 01/11/2022] [Accepted: 02/22/2022] [Indexed: 01/01/2023] Open
Abstract
BACKGROUND Nonalcoholic fatty liver disease (NAFLD) among Latinos is partially attributed to a prevalent C>G polymorphism in the patatin-like phospholipase 3 (PNPLA3) gene. Cross-sectional analyses in Latino children showed the association between dietary sugar and liver fat was exacerbated by GG genotype. Pediatric feeding studies show extreme sugar restriction improves liver fat, but no prior trial has examined the impact of a clinical intervention or whether effects differ by PNPLA3 genotype. OBJECTIVES We aimed to test effects of a clinical intervention to reduce dietary sugar compared with standard dietary advice on change in liver fat, and secondary-endpoint changes in liver fibrosis, liver enzymes, and anthropometrics; and whether effects differ by PNPLA3 genotype (assessed retrospectively) in Latino youth with obesity (BMI ≥ 95th percentile). METHODS This parallel-design trial randomly assigned participants (n = 105; mean baseline liver fat: 12.7%; mean age: 14.8 y) to control or sugar reduction (goal of ≤10% of calories from free sugar) for 12 wk. Intervention participants met with a dietitian monthly and received delivery of bottled water. Changes in liver fat, by MRI, were assessed by intervention group via general linear models. RESULTS Mean free sugar intake decreased in intervention compared with control [11.5% to 7.3% compared with 13.9% to 10.7% (% energy), respectively; P = 0.02], but there were no significant effects on liver outcomes or anthropometrics (Pall > 0.10), and no PNPLA3 interactions (Pall > 0.10). In exploratory analyses, participants with whole-body fat mass (FM) reduction (mean ± SD: -1.9 ± 2.4 kg), irrespective of randomization, had significant reductions in liver fat compared with participants without FM reduction (median: -2.1%; IQR: -6.5% to -0.8% compared with 0.3%; IQR: -1.0% to 1.1%; P < 0.001). CONCLUSIONS In Latino youth with obesity, a dietitian-led sugar reduction intervention did not improve liver outcomes compared with control, regardless of PNPLA3 genotype. Results suggest FM reduction is important for liver fat reduction, confirming clinical recommendations of weight loss and a healthy diet for pediatric NAFLD.This trial was registered at clinicaltrials.gov as NCT02948647.

Abstract
Coronavirus disease 2019 (COVID-19) disparities among vulnerable populations are of paramount concern that extend to vaccine administration. With recent uptick in infection rates, dominance of the delta variant, and authorization of a third booster shot, understanding the population-level vaccine coverage dynamics and underlying sociodemographic factors is critical for achieving equity in public health outcomes. This study aimed to characterize the scope of vaccine inequity in California counties through modeling the trends of vaccination using the Social Vulnerability Index (SVI). Overall SVI, its four themes, and 9228 data points of daily vaccination numbers from December 15, 2020, to May 23, 2021, across all 58 California counties were used to model the growth velocity and anticipated maximum proportion of population vaccinated, defined as having received at least one dose of vaccine. Based on the overall SVI, the vaccination coverage velocity was lower in counties in the high vulnerability category (v = 0.0346, 95% CI 0.0334, 0.0358) compared to moderate (v = 0.0396, 95% CI 0.0385, 0.0408) and low (v = 0.0414, 95% CI 0.0403, 0.0425) vulnerability categories. SVI Theme 3 (minority status and language) yielded the largest disparity in coverage velocity between low and high-vulnerable counties (v = 0.0423 versus v = 0.035, P < 0.001). Based on the current trajectory, while counties in low-vulnerability category of overall SVI are estimated to achieve a higher proportion of vaccinated individuals, our models yielded a higher asymptotic maximum for highly vulnerable counties of Theme 3 (K = 0.544, 95% CI 0.527, 0.561) compared to low-vulnerability counterparts (K = 0.441, 95% CI 0.432, 0.450). The largest disparity in asymptotic proportion vaccinated between the low and high-vulnerability categories was observed in Theme 2 describing the household composition and disability (K = 0.602, 95% CI 0.592, 0.612; versus K = 0.425, 95% CI 0.413, 0.436). Overall, the large initial disparities in vaccination rates by SVI status attenuated over time, particularly based on Theme 3 status which yielded a large decrease in cumulative vaccination rate ratio of low to high-vulnerability categories from 1.42 to 0.95 (P = 0.002). This study provides insight into the problem of COVID-19 vaccine disparity across California which can help promote equity during the current pandemic and guide the allocation of future vaccines such as COVID-19 booster shots.

Abstract
OBJECTIVE Our objectives were to assess in perinatal women: the most effective methods used to meet social support needs during COVID-19, the impact of COVID-19 on self-reported social support levels, and how perceived change in social support related to distress, depression, and mental health. DESIGN One-time survey administered from April to August 2020 SETTING: Online PARTICIPANTS: Pregnant and postpartum women with infants less than 6 months of age MEASUREMENT AND FINDINGS: Participants indicated the methods they used to meet social support needs during COVID-19. They self-rated their social support level pre- and during pandemic and their distress, depressive symptoms, and mental health changes on a Likert scale. Out of 1142 participants, the most effective methods for obtaining social support during the pandemic were virtual means (e.g. video call) and interaction with friends. There was a significant difference in distribution of self-reported levels of social support before and during the pandemic, with more respondents reporting a decrease in support. Decreases in social support were associated with higher distress levels, higher levels of depressive symptoms, and poorer mental health. KEY CONCLUSIONS Perinatal women reported decreased social support during the COVID-19 pandemic which was associated with poorer mental health. Using virtual means of social support and support provided by friends had the largest positive effect on perceived social support levels. IMPLICATIONS FOR PRACTICE Interventions using virtual support means from friends may be helpful to improve social support and mental health in this population.

Abstract
IMPORTANCE Nonnutritive sweeteners (NNSs) are used as an alternative to nutritive sweeteners to quench desire for sweets while reducing caloric intake. However, studies have shown mixed results concerning the effects of NNSs on appetite, and the associations between sex and obesity with reward and appetitive responses to NNS compared with nutritive sugar are unknown. OBJECTIVE To examine neural reactivity to different types of high-calorie food cues (ie, sweet and savory), metabolic responses, and eating behavior following consumption of sucralose (NNS) vs sucrose (nutritive sugar) among healthy young adults. DESIGN, SETTING, AND PARTICIPANTS In a randomized, within-participant, crossover trial including 3 separate visits, participants underwent a functional magnetic resonance imaging task measuring blood oxygen level-dependent signal in response to visual cues. For each study visit, participants arrived at the Dornsife Cognitive Neuroimaging Center of University of Southern California at approximately 8:00 am after a 12-hour overnight fast. Blood was sampled at baseline and 10, 35, and 120 minutes after participants received a drink containing sucrose, sucralose, or water to measure plasma glucose, insulin, glucagon-like peptide(7-36), acyl-ghrelin, total peptide YY, and leptin. Participants were then presented with an ad libitum meal. Participants were right-handed, nonsmokers, weight-stable for at least 3 months before the study visits, nondieters, not taking medication, and with no history of eating disorders, illicit drug use, or medical diagnoses. Data analysis was performed from March 2020 to March 2021. INTERVENTIONS Participants ingested 300-mL drinks containing either sucrose (75 g), sucralose (individually sweetness matched), or water (as a control). MAIN OUTCOMES AND MEASURES Primary outcomes of interest were the effects of body mass index (BMI) status and sex on blood oxygen level-dependent signal to high-calorie food cues, endocrine, and feeding responses following sucralose vs sucrose consumption. Secondary outcomes included neural, endocrine, and feeding responses following sucrose vs water and sucralose vs water (control) consumption, and cue-induced appetite ratings following sucralose vs sucrose (and vs water). RESULTS A total of 76 participants were randomized, but 2 dropped out, leaving 74 adults (43 women [58%]; mean [SD] age, 23.40 [3.96] years; BMI range, 19.18-40.27) who completed the study. In this crossover design, 73 participants each received water (drink 1) and sucrose (drink 2), and 72 participants received water (drink 1), sucrose (drink 2), and sucralose (drink 3). Sucrose vs sucralose was associated with greater production of circulating glucose, insulin, and glucagon-like peptide-1 and suppression of acyl-ghrelin, but no differences were found for peptide YY or leptin. BMI status by drink interactions were observed in the medial frontal cortex (MFC; P for interaction < .001) and orbitofrontal cortex (OFC; P for interaction = .002). Individuals with obesity (MFC, β, 0.60; 95% CI, 0.38 to 0.83; P < .001; OFC, β, 0.27; 95% CI, 0.11 to 0.43; P = .002), but not those with overweight (MFC, β, 0.02; 95% CI, -0.19 to 0.23; P = .87; OFC, β, -0.06; 95% CI, -0.21 to 0.09; P = .41) or healthy weight (MFC, β, -0.13; 95% CI, -0.34 to 0.07; P = .21; OFC, β, -0.08; 95% CI, -0.23 to 0.06; P = .16), exhibited greater responsivity in the MFC and OFC to savory food cues after sucralose vs sucrose. Sex by drink interactions were observed in the MFC (P for interaction = .03) and OFC (P for interaction = .03) after consumption of sucralose vs sucrose. Female participants had greater MFC and OFC responses to food cues (MFC high-calorie vs low-calorie cues, β, 0.21; 95% CI, 0.05 to 0.37; P = .01; MFC sweet vs nonfood cues, β, 0.22; 95% CI, 0.02 to 0.42; P = .03; OFC food vs nonfood cues, β, 0.12; 95% CI, 0.02 to 0.22; P = .03; and OFC sweet vs nonfood cues, β, 0.15; 95% CI, 0.03 to 0.27; P = .01), but male participants' responses did not differ (MFC high-calorie vs low-calorie cues, β, 0.01; 95% CI, -0.19 to 0.21; P = .90; MFC sweet vs nonfood cues, β, -0.04; 95% CI, -0.26 to 0.18; P = .69; OFC food vs nonfood cues, β, -0.08; 95% CI, -0.24 to 0.08; P = .32; OFC sweet vs nonfood cues, β, -0.11; 95% CI, -0.31 to 0.09; P = .31). A sex by drink interaction on total calories consumed during the buffet meal was observed (P for interaction = .03). Female participants consumed greater total calories (β, 1.73; 95% CI, 0.38 to 3.08; P = .01), whereas caloric intake did not differ in male participants (β, 0.68; 95% CI, -0.99 to 2.35; P = .42) after sucralose vs sucrose ingestion. CONCLUSIONS AND RELEVANCE These findings suggest that female individuals and those with obesity may be particularly sensitive to disparate neural responsivity elicited by sucralose compared with sucrose consumption.

Appetite-Regulating Hormones Are Reduced After Oral Sucrose vs Glucose: Influence of Obesity, Insulin Resistance, and Sex. J Clin Endocrinol Metab 2021; 106:654-664. [PMID: 33300990 PMCID: PMC7947782 DOI: 10.1210/clinem/dgaa865] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/01/2020] [Indexed: 11/19/2022]
Abstract
CONTEXT Fructose compared to glucose has adverse effects on metabolic function, but endocrine responses to oral sucrose vs glucose is not well understood. OBJECTIVE We investigated how oral sucrose vs glucose affected appetite-regulating hormones, and how biological factors (body mass index [BMI], insulin sensitivity, sex) influence endocrine responses to these 2 types of sugar. DESIGN Sixty-nine adults (29 men; 23.22 ± 3.74 years; BMI 27.03 ± 4.96 kg/m2) completed the study. On 2 occasions, participants consumed 300-mL drinks containing 75 g of glucose or sucrose. Blood was sampled at baseline, 10, 35, and 120 minutes post drink for plasma glucose, insulin, glucagon-like peptide (GLP-1)(7-36), peptide YY (PYY)total, and acyl-ghrelin measures. Hormone levels were compared between conditions using a linear mixed model. Interaction models were performed, and results were stratified to assess how biological factors influence endocrine responses. RESULTS Sucrose vs glucose ingestion provoked a less robust rise in glucose (P < .001), insulin (P < .001), GLP-1 (P < .001), and PYY (P = .02), whereas acyl-ghrelin suppression was similar between the sugars. We found BMI status by sugar interactions for glucose (P = .01) and PYY (P = .03); obese individuals had smaller increases in glucose and PYY levels after consuming sucrose vs glucose. There were interactions between insulin sensitivity and sugar for glucose (P = .003) and insulin (P = .04), and a sex by sugar interaction for GLP-1 (P = .01); men demonstrated smaller increases in GLP-1 in response to oral sucrose vs glucose. CONCLUSION Sucrose is less efficient at signaling postprandial satiation than glucose, and biological factors influence differential hormone responses to sucrose vs glucose consumption.

Abstract
For critically ill burn patients without a next of kin, the medical team is tasked with becoming the surrogate decision maker. This poses ethical and legal challenges for burn providers. Despite this frequent problem, there has been no investigation of how the presence of a next of kin affects treatment in burn patients. To evaluate this relationship, a retrospective chart review was performed on a cohort of patients who died during the acute phase of their burn care. Variables collected included age, gender, length of stay, total body surface area, course of treatment, and presence of a next of kin. In total, 67 patients met the inclusion criteria. Of these patients, 14 (21%) did not have a next of kin involved in medical decisions. Patients without a next of kin were significantly younger (P = .02), more likely to be homeless (P < .01), had higher total body surface area burns (P = .008), had shorter length of stay (P < .001), and were five times less likely to receive comfort care (P = .01). Differences in gender and ethnicity were not statistically significant. We report that patients without a next of kin present to participate in medical decisions are transitioned to comfort care less often despite having a higher burden of injury. This disparity in standard of care demonstrates a need for a cultural shift in burn care to prevent the suffering of these marginalized patients. Burn providers should be empowered to reduce suffering when no decision maker is present.

Above the influence of vaping: Peer leader influence and diffusion of a network-informed preventive intervention. Addict Behav 2021; 113:106693. [PMID: 33069108 DOI: 10.1016/j.addbeh.2020.106693] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/30/2020] [Revised: 09/02/2020] [Accepted: 10/01/2020] [Indexed: 10/23/2022]
Abstract
Using social networks to inform prevention efforts is promising but has not been applied to vaping. To address this gap, we pilot tested the peer-led Above the Influence of Vaping (ATI-V) and examined diffusion through 8th grade networks in three schools. Fifty students, nominated and trained as Peer Leaders, implemented prevention campaigns informed by communication science, including gain-loss messaging and social norming. Across schools, 86-91% of students (N = 377) completed measures (pre-post) of electronic vaping product (EVP) use and attitudes, and named close friends and adults to construct social networks. Using baseline reports, we classified students as Recent EVP Users (10%), Vulnerable Nonusers (24%), or Resolute Nonusers (66%). Peer Leaders had reach through friendship connections to students at varying risk of vaping; 12-16 weeks after Peer Leaders were trained and began implementing campaigns, 79% of Resolute Nonusers and 74% of Recent Users/Vulnerable Nonusers reported exposure to a vaping prevention message. Students with more Peer Leader friends were less likely to report recent EVP use (OR = 0.41) or intention to use an EVP (B = 0.12) on post-surveys, supporting the intervention conceptual model positing diffusion through friendship networks. Use of student-nominated peer leaders was supported by network analyses showing EVP Users integrated within the friendship network, having more high-risk friends, and fewer adult connections. This evidence is the first to show that adolescent Peer Leaders with ongoing mentoring and science-informed campaigns can potentially reduce EVP acceptability and use. Areas for refining ATI-V include increasing consistency of campaign exposure across schools.

Presentation, Management, and Outcomes Across the Rural-Urban Continuum for Hepatocellular Carcinoma. JNCI Cancer Spectr 2021; 5:pkaa100. [PMID: 33442663 PMCID: PMC7791625 DOI: 10.1093/jncics/pkaa100] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/26/2020] [Accepted: 09/30/2020] [Indexed: 12/15/2022] Open
Abstract
Background Hepatocellular carcinoma is 1 of few cancers with rising incidence and mortality in the United States. Little is known about disease presentation and outcomes across the rural-urban continuum. Methods Using the population-based Surveillance, Epidemiology, and End Results registry, we identified adults with incident hepatocellular carcinoma between 2000 and 2016. Urban, suburban, and rural residence at time of cancer diagnosis were categorized by the Census Bureau’s percent of the population living in nonurban areas. We examined association between place of residence and overall survival. Secondary outcomes were late tumor stage and receipt of therapy. Results Of 83 368 incident cases of hepatocellular carcinoma, 75.8%, 20.4%, and 3.8% lived in urban, suburban, and rural communities, respectively. Median survival was 7 months (interquartile range = 2-24). All stage and stage-specific survival differed by place of residence, except for distant stage. In adjusted models, rural and suburban residents had a respective 1.09-fold (95% confidence interval [CI] = 1.04 to 1.14; P < .001) and 1.08-fold (95% CI = 1.05 to 1.10; P < .001) increased hazard of overall mortality as compared with urban residents. Furthermore, rural and suburban residents had 18% (odds ratio [OR] = 1.18, 95% CI = 1.10 to 1.27; P < .001) and 5% (OR = 1.05, 95% CI = 1.02 to 1.09; P = .003) higher odds of diagnosis at late stage and were 12% (OR = 0.88, 95% CI = 0.80 to 0.94; P < .001) and 8% (OR = 0.92, 95% CI = 0.88 to 0.95; P < .001) less likely to receive treatment, respectively, compared with urban residents. Conclusions Residence in a suburban and rural community at time of diagnosis was independently associated with worse indicators across the cancer continuum for liver cancer. Further research is needed to elucidate the primary drivers of these rural-urban disparities.

Associations of maternal fructose and sugar-sweetened beverage and juice intake during lactation with infant neurodevelopmental outcomes at 24 months. Am J Clin Nutr 2020; 112:1516-1522. [PMID: 33020800 PMCID: PMC7727478 DOI: 10.1093/ajcn/nqaa255] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/22/2020] [Accepted: 08/14/2020] [Indexed: 12/11/2022] Open
Abstract
BACKGROUND Our prior studies revealed that infant somatic growth is influenced by fructose in breast milk, and fructose in breast milk is increased in response to maternal sugar-sweetened beverage (SSB) intake in lactation. It is unknown whether infant neurodevelopmental outcomes are also influenced by maternal SSBs in lactation. OBJECTIVES To determine whether infant cognitive development at 24 postnatal months was influenced by maternal fructose consumption during lactation, and whether this relation persisted after accounting for maternal SSB and juice (SSB + J) intake. METHODS Hispanic mother-infant pairs (n = 88) were recruited across the spectrum of prepregnancy BMI. Mothers completed two 24-h dietary recalls at 1 and 6 postnatal months, and reported breastfeedings per day. The Bayley-III Scales of Infant Development were administered at 24 postnatal months to assess infant cognition. Linear regressions were used to examine associations, reported as unstandardized (B) coefficients, 95% CIs, and P values. RESULTS Mothers consumed 1656 ± 470 kcal, 21.8 ± 12 g fructose, and 2.5 ± 2.6 servings SSBs + J, and reported 6.9 ± 2.1 breastfeedings per day at 1 postnatal month. Controlling for maternal age, prepregnancy BMI, education level, kilocalories, infant age, sex, and birthweight revealed that infant cognitive development scores at 24 postnatal months correlated inversely with maternal fructose consumption at 1 postnatal month (B = -0.08; 95% CI = -0.13, -0.03; P < 0.01). The association of infant cognitive development scores with maternal fructose consumption was no longer significant after adjustment for maternal SSB + J intake (B = -0.05; 95% CI = -0.10, 0.00; P = 0.07), whereas maternal SSB + J intake was significant in the same model (B = -0.29; 95% CI = -0.52, -0.05; P = 0.02). Infant cognitive development scores were not associated with maternal fructose and SSB + J consumption at 6 postnatal months. CONCLUSIONS Our findings suggest that infant neurodevelopmental outcomes at 24 postnatal months can be adversely influenced by maternal fructose intake in early lactation, and this could be attributed to maternal SSB + J intake.

Coronavirus Disease 2019 (COVID-19): A Modeling Study of Factors Driving Variation in Case Fatality Rate by Country. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2020; 17:ijerph17218189. [PMID: 33167564 PMCID: PMC7664233 DOI: 10.3390/ijerph17218189] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/21/2020] [Revised: 10/26/2020] [Accepted: 11/02/2020] [Indexed: 12/20/2022]
Abstract
Background: The novel Severe Acute Respiratory Syndrome Coronavirus-2 has led to a global pandemic in which case fatality rate (CFR) has varied from country to country. This study aims to identify factors that may explain the variation in CFR across countries. Methods: We identified 24 potential risk factors affecting CFR. For all countries with over 5000 reported COVID-19 cases, we used country-specific datasets from the WHO, the OECD, and the United Nations to quantify each of these factors. We examined univariable relationships of each variable with CFR, as well as correlations among predictors and potential interaction terms. Our final multivariable negative binomial model included univariable predictors of significance and all significant interaction terms. Results: Across the 39 countries under consideration, our model shows COVID-19 case fatality rate was best predicted by time to implementation of social distancing measures, hospital beds per 1000 individuals, percent population over 70 years, CT scanners per 1 million individuals, and (in countries with high population density) smoking prevalence. Conclusion: Our model predicted an increased CFR for countries that waited over 14 days to implement social distancing interventions after the 100th reported case. Smoking prevalence and percentage population over the age of 70 years were also associated with higher CFR. Hospital beds per 1000 and CT scanners per million were identified as possible protective factors associated with decreased CFR.

Peer-adult network structure and suicide attempts in 38 high schools: implications for network-informed suicide prevention. J Child Psychol Psychiatry 2019; 60:1065-1075.

Abstract
BACKGROUND Strengthening social integration could prevent suicidal behavior. However, minimal research has examined social integration through relationship network structure. To address this important gap, we tested whether structural characteristics of school networks predict school rates of ideation and attempts. METHODS In 38 US high schools, 10,291 students nominated close friends and trusted adults to construct social networks. We used mixed-effects logistic regression models to test individual student networks and likelihood of suicidal ideation (SI) and suicide attempts (SA); and linear regression models to estimate associations between school network characteristics and school rates of SI, SA, and SA among all with ideation. RESULTS Lower peer network integration and cohesion increased likelihood of SI and SA across individual and school-level models. Two factors increased SA: student isolation from adults and suicidal students' popularity and clustering. A multivariable model identified higher SA in schools where youth-adult relationships were concentrated in fewer students (B = 4.95 [1.46, 8.44]) and suicidal students had higher relative popularity versus nonsuicidal peers (B = 0.93 [0.10, 1.77]). Schools had lower SA rates when more students named the same trusted adults named by friends and many students named the same trusted adults. When adjusting for depression, violence victimization and bullying, estimates for adult network characteristics were substantially unchanged whereas some peer effects decreased. CONCLUSIONS Schoolwide peer and youth-adult relationship patterns influence SA rates beyond individual student connections. Network characteristics associated with suicide attempts map onto three theory-informed domains: social integration versus thwarted relational needs, group cohesion, and suicidal students' social influence. Network interventions addressing these processes, such as maximizing youth-adult connections schoolwide and heightening influence of youth with healthy coping, could create more protective schools. Longitudinal and intervention studies are needed to determine how schools differentiate in network structure and clarify reciprocal dynamics between network characteristics and suicidal behavior.

Is Online Partner-Seeking Associated with Increased Risk of Condomless Sex and Sexually Transmitted Infections Among Individuals Who Engage in Heterosexual Sex? A Systematic Narrative Review. ARCHIVES OF SEXUAL BEHAVIOR 2019; 48:533-555. [PMID: 30155796 DOI: 10.1007/s10508-018-1235-2] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/11/2016] [Revised: 05/11/2018] [Accepted: 05/14/2018] [Indexed: 06/08/2023]
Abstract
Use of Internet websites and mobile applications to meet potential romantic and sexual partners is becoming increasingly popular. While the Internet might foster better communication and sexual negotiation between partners, it can also be a deceptive environment that instigates and accelerates sexual risk-taking. Given the complexities of the Internet, it is critical to examine the association between risky sexual behaviors (RSBs) and online partner-seeking. Five databases (i.e., Google Scholar, PubMed, PsycINFO, Web of Science, and Ovid Medline) were searched for articles published before September 10, 2017, that examined the association between online partner solicitation (either for romantic and/or sexual reasons) and RSBs. Studies were eligible for inclusion if they were empirical papers published in English-language peer-reviewed journals looking at samples of online partner seekers who practice heterosexual sex (with a comparison group) and reporting either condom use or sexually transmitted infections (STIs) status, which were the two primary outcomes. A total of 25 studies met the criteria to be included in our review. Results from this literature search do not indicate a clear association between online partner-seeking and condom use or STI status. Potential moderators (i.e., age, gender, reasons for online partner solicitation, duration of Internet correspondence, and Internet modalities) that should be included in future research were identified. Sexual health prevention efforts should address methods to negotiate safe practices between sexual partners and to encourage healthy non-virtual relationships, particularly among vulnerable populations.

Diffusion of a Peer-Led Suicide Preventive Intervention Through School-Based Student Peer and Adult Networks. Front Psychiatry 2018; 9:598.

Abstract
Background: Peer-led interventions have been applied to prevent various health behavior problems and may be an important complement to individual-level suicide prevention approaches. Sources of Strength trains student "peer leaders" in secondary schools to conduct prevention activities that encourage other students to build healthy social bonds and strengthen help-seeking norms. Prior work examining diffusion of peer-led programs has focused on youths' closeness to peer leaders but minimally on other factors such as connections to adults and suicidal behavior. Methods: We examined implementation and dissemination of Sources of Strength in 20 schools. Over 1 year 533 students were trained as peer leaders and 3,730 9th-12th graders completed baseline surveys assessing friendships and adults at school, and suicidal thoughts/behaviors; and end-of-year surveys reporting intervention exposure: viewed poster/video, attended presentation, direct peer communication, and activity participation. Chi-square tests compared exposure rates by student and network characteristics. Multi-level logistic regression models tested predictors of exposure across individual and school-level characteristics. Results: Exposure to the intervention varied greatly by school and by individual student characteristics and network position. Training more peer leaders increased school-wide exposure for all modalities except presentation (Bs 0.06-0.10, p's < 0.05). In multivariate models, exposure was consistently higher for students closer to peer leaders in the friendship network (ORs 1.13-1.54, p's < 0.05) and students who named more trusted adults (ORs 1.08-1.16, p's < 0.001); and lower for males (ORs 0.56-0.83, p's < 0.05). In multivariate models, training more students as peer leaders predicted exposure to poster-video and direct peer communication in larger schools (OR = 3.34 and 2.87, respectively). Network characteristics influenced exposure similarly for students with suicidal thoughts and behaviors. Discussion: Our findings confirm prior work showing the importance of personal affiliations to peer leaders and natural networks as a medium for diffusion of peer-led prevention efforts. We build on that work by showing independent effects of closeness to adults at school and number of peer leaders trained. There is a need to strategically select peer leaders to maximize closeness to students school-wide, particularly in larger schools. Additional work is required for Sources of Strength to devise messaging strategies to engage males and students isolated from adults at school.

Abstract
OBJECTIVE Stress has been associated with high-calorie, low-nutrient food intake (HCLN) and emotion-driven eating (EDE). However, effects on healthy food intake remain unknown. This study examined two facets of stress (self-efficacy, perceived helplessness) and food consumption, mediated by EDE. METHODS Cross-sectional data from fourth-graders (n=978; 52% female, 28% Hispanic) in an obesity intervention used self-report to assess self-efficacy, helplessness, EDE, fruit/vegetable (FV) intake, and high-calorie/low-nutrient (HCLN) food. RESULTS Higher stress self-efficacy was associated with higher FV intake, β=.354, p<0.001, and stress perceived helplessness had an indirect effect on HCLN intake through emotion-driven eating, indirect effect=.094, p<0.001; χ(2)(347)=659.930, p<0.001, CFI=0.940, TLI=0.930, RMSEA=0.030, p=1.00, adjusting for gender, ethnicity, BMI z-score, and program group. CONCLUSIONS AND IMPLICATIONS Stress self-efficacy may be more important for healthy food intake and perceived helplessness may indicate emotion-driven eating and unhealthy snack food intake. Obesity prevention programs may consider teaching stress management techniques to avoid emotion-driven eating.

Abstract
OBJECTIVES To examine the relationship between medical home quality and measures of daily life experiences among children with asthma. METHODS A nationally representative sample of children from the 2007 National Survey of Children's Health (NSCH), aged 6-17 years (n = 6357), who have asthma was used to assess the relationship of a quality medical home and its features with their daily life experiences. Five medical home features - access, continuity, comprehensiveness, family-centered care, and coordination of care - were examined individually and in total in relation to measures of school engagement (missed school days, parents contacted about problems with the child, repeating a grade since kindergarten) and after-school activity participation (physical activity, sports participation, and community service or volunteer work). RESULTS Before and after adjustment for personal characteristics, health insurance status, family environment, neighborhood variables, and asthma severity, total medical home score was associated with more days exercised [beta (B) = 0.10, p < .05] and a greater likelihood of having performed community service or volunteer work [odds ratio (OR) = 1.16, CI: 1.02-1.31]. Additionally, the medical home features of access, comprehensiveness, and family-centered care remained favorably associated with three of the six measures of school engagement and after-school activity participation, even after adjustment. CONCLUSION Medical home quality - particularly the features of access, comprehensiveness, and family-centered care - is positively associated with the daily life experiences of children with asthma. Working to enhance these aspects of primary care might be one place to start in improving the management of children's chronic conditions and their quality of life.

Abstract
OBJECTIVES To examine socio-demographic disparities associated with a quality medical home. METHODS A nationally representative sample of children ages 0-17 years (n = 102,353) from the 2003 National Survey of Children's Health. Risk factors including non-white race/ethnicity, income <200% of the federal poverty level (FPL), uninsured, parent education lesser than high school, and non-English primary household language, were examined in relation to a quality medical home separately and together as a "profile" of risk. Fourteen questions were used to measure five medical home features: access, continuity, comprehensiveness, family-centered care, and coordination. Quality was defined as a value greater than median for each feature and for an overall score. RESULTS Before and after adjustment for child demographics and health status, all studied risk factors were associated with poorer quality medical home features. Uninsured [odds ratio (OR) = 0.43, 95% confidence interval (CI): 0.40-0.47] and low-income children (OR = 0.65, CI: 0.62-0.69) had among the lowest odds of a quality medical home overall and across most features, except coordination that showed an opposite trend. Summarized through risk profiles, children experiencing all five risk factors had 93% lower odds of a quality medical home overall (OR = 0.07, CI: 0.04-0.25) compared to zero risk children. CONCLUSION This study demonstrates large national disparities in the quality of a medical home for children. That disparities were most prevalent for the uninsured and those in or near poverty, both modifiable risk factors, suggests that reforms to increase coverage and to lift families out of poverty are essential to assuring that children have access to the full complement of appropriate health care services including a quality medical home.

Disparities in the national prevalence of a quality medical home for children with asthma. Acad Pediatr 2009; 9:234-41. [PMID: 19608124 DOI: 10.1016/j.acap.2009.01.006] [Citation(s) in RCA: 23] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/13/2008] [Revised: 01/15/2009] [Accepted: 01/29/2009] [Indexed: 10/21/2022]
Abstract
OBJECTIVE The aim of this study was to examine sociodemographic disparities in having a quality medical home among a nationally representative sample of children with asthma. METHODS The study examined data from the 2003 National Survey of Children's Health to identify 8360 children aged 2-17 years with asthma. Risk factors including nonwhite race/ethnicity, income <200% of the federal poverty level (FPL), uninsured, parent education less than high school, and non-English language, were examined individually and as a profile of risk in relation to a quality medical home. Fourteen questions were used to measure 5 medical home features: access, continuity, comprehensiveness, family-centered care, and coordination. A poorer quality medical home was defined as < or =66 on a 100-point scale-corresponding to the feature being present less than "usually"-for each feature and for an overall score. RESULTS Before and after adjustment for demographics and asthma difficulties, most risks except less than high school parent education were related to a poorer quality medical home. Uninsured children had the highest odds of a poorer quality medical home overall (adjusted odds ratio [OR] 5.19, 95% confidence interval [CI] 3.52-7.65) and across most features, except for coordination. Children experiencing 3+ risks had 8.56 times the odds of a poorer quality medical home overall (95% CI 4.95-14.78) versus zero risks. CONCLUSIONS This study demonstrates large national disparities in a quality medical home for children with asthma. That disparities were most prevalent for the uninsured (insurance being a modifiable risk factor) suggests increasing coverage is essential to assuring that children obtain a quality medical home.
