Birth Weight Moderates The Association Between Obesity And Mortality Rate, Gregory Pavela, Nengjun Yi, Luis Mestre, Pengcheng Xun, David B Allison

Children’s Nutrition Research Center Staff Publications

Purpose: The strength of the association between obesity and mortality rate (MR) varies by body mass index (BMI) and sociodemographic groups. We test the hypothesis that the association between obesity and MR varies, in part, due to the moderating effect of parental BMI and birth weight.

Methods: Data come from the 1958 National Child Development Study, an ongoing longitudinal dataset initiated in 1958 with baseline measures of birth weight from 18,059 infants born in Great Britain over 1 week. We tested whether the association between BMI and MR was moderated by parental BMI and birth weight using generalized additive proportional …

Methods: This was a mixed methods study that combined semistructured interviews and surveys to assess the perceived usefulness and ease of use, intent to use, and factors affecting tool adoption. We recruited clinicians and staff members from practices that manage diabetes. During …

Effectiveness Of Lactation Cookies On Human Milk Production Rates: A Randomized Controlled Trial, Ana M Palacios, Michelle I Cardel, Erik Parker, Stephanie Dickinson, Valerie R Houin, Bridget Young, David B Allison

Children’s Nutrition Research Center Staff Publications

Background: Expensive lactation cookies (LCs) are marketed as milk boosters; however, their effectiveness remains unknown.

Objectives: The objective of this study was to evaluate the effectiveness of the 1-mo daily intake of LCs on changes in objective and subjective milk production and breastfeeding self-efficacy.

Methods: This is a 1-mo, randomized controlled trial among 18-45-y-old exclusively lactating parents of healthy, term, 2-mo-old infants living in the United States from March to December 2021. Participants (n = 176) were randomly assigned to eat daily 56.5 g of either LCs with "galactagogues" (oatmeal, brewer's yeast, flax seeds, and fenugreek) or conventional cookies containing …

The Effect Of A Pharmaceutical Ghrelin Agonist On Lifespan In C57bl/6j Male Mice: A Controlled Experiment, Kathryn A Kaiser, Inga Kadish, Thomas Van Groen, Daniel L Smith, Stephanie Dickinson, Beate Henschel, Erik S Parker, Andrew W Brown, David B Allison

Children’s Nutrition Research Center Staff Publications

Interventions for animal lifespan extension like caloric restriction (CR) have identified physiologic and biochemical pathways related to hunger and energy-sensing status as possible contributors, but mechanisms have not been fully elucidated. Prior studies using ghrelin agonists show greater food intake but no effect on lifespan in rodent models. This experiment in male C57BL/6J mice tested the influence of ghrelin agonism for perceived hunger, in the absence of CR, on longevity. Mice aged 4 weeks were allowed to acclimate for 2 weeks prior to being assigned (N = 60/group). Prior to lights off daily (12:12 cycle), animals were fed a ghrelin …

Reflection Spectroscopy-Assessed Skin Carotenoids Are Sensitive To Change In Carotenoid Intake In A 6-Week Randomized Controlled Feeding Trial In A Racially/Ethnically Diverse Sample, Stephanie Jilcott Pitts, Nancy E Moran, Melissa N Laska, Qiang Wu, Lisa Harnack, Stacey Moe, Pamela Carr-Manthe, Elizabeth Gates, Jocelyn Chang, Yusuf Zaidi, Abigail Gelineau, Lauren Berg, Neal E Craft

Children’s Nutrition Research Center Staff Publications

Background: Reflection spectroscopy, utilized by the Veggie Meter, is a less-expensive, noninvasive method to quantify skin carotenoids and is a valid approximation of fruit and vegetable (FV) intake. However, it is unknown to what degree Veggie Meter-assessed skin carotenoid score change is responsive to changes in carotenoid intake.

Objectives: This study aimed to evaluate Veggie Meter-assessed skin carotenoid score response in a 6-wk randomized controlled trial of a carotenoid-containing juice to determine whether the Veggie Meter can be used to detect nutritionally relevant changes in carotenoid intake; and to compare skin and plasma carotenoid responses with the 6-wk trial.

Methods: …

Use Of Dual Genomic Sequencing To Screen Mitochondrial Diseases In Pediatrics: A Retrospective Analysis, Teng-Hui Wu, Jing Peng, Li Yang, Yan-Hui Chen, Xiu-Lan Lu, Jiao-Tian Huang, Jie-Yu You, Wen-Xian Ou-Yang, Yue-Yu Sun, Yi-Nan Xue, Xiao Mao, Hui-Ming Yan, Rong-Na Ren, Jing Xie, Zhi-Heng Chen, Victor-Wei Zhang, Gui-Zhen Lyu, Fang He

Children’s Nutrition Research Center Staff Publications

Mitochondrial diseases (MDs) were a large group multisystem disorders, attributable in part to the dual genomic control. The advent of massively sequencing has improved diagnostic rates and speed, and was increasingly being used as a first-line diagnostic test. Paediatric patients (aged <  18 years) who underwent dual genomic sequencing were enrolled in this retrospective multicentre study. We evaluated the mitochondrial disease criteria (MDC) and molecular diagnostic yield of dual genomic sequencing. Causative variants were identified in 177 out of 503 (35.2%) patients using dual genomic sequencing. Forty-six patients (9.1%) had mitochondria-related variants, including 25 patients with nuclear DNA (nDNA) variants, 15 with mitochondrial DNA (mtDNA) variants, and six with dual genomic variants (MT-ND6 and POLG; MT-ND5 and RARS2; MT-TL1 and NARS2; MT-CO2 and NDUFS1; MT-CYB and SMARCA2; and CHRNA4 and MT-CO3). Based on the MDC, 15.2% of the patients with mitochondria-related variants were classified as "unlikely to have mitochondrial disorder". Moreover, 4.5% of the patients with non-mitochondria-related variants and 1.43% with negative genetic tests, were classified as "probably having mitochondrial disorder". Dual genomic sequencing in suspected MDs provided a more comprehensive and accurate diagnosis for pediatric patients, especially for patients with dual genomic variants.

Child Weight Status: The Role Of Feeding Styles And Highly Motivated Eating In Children, Maria A Papaioannou, Thomas G Power, Teresia M O'Connor, Jennifer O Fisher, Nilda E Micheli, Sheryl O Hughes

Children’s Nutrition Research Center Staff Publications

Although parental feeding plays an important role in child eating and weight status, high food motivation among children may also be a factor shaping how feeding impacts child weight. This study explored whether individual differences in preschool children’s food motivation interacted with mothers’ feeding styles in predicting subsequent child weight status. Participants included 129 Hispanic Head Start mother/child dyads. Data were collected at ages 4–5 years (Time 1) and 7–9 (Time 3). Staff measured heights/weights and observed children in an eating in the absence of hunger task. Mothers reported on feeding styles/practices and children’s eating behaviors.

Participation data demonstrated high adherence in treatment and comparison groups. Descriptive statistics were calculated …

Tracking The Evolution Of Esophageal Squamous Cell Carcinoma Under Dynamic Immune Selection By Multi-Omics Sequencing, Sijia Cui, Nicholas Mcgranahan, Jing Gao, Peng Chen, Wei Jiang, Lingrong Yang, Li Ma, Junfang Liao, Tian Xie, Congying Xie, Tariq Enver, Shixiu Wu

Children’s Nutrition Research Center Staff Publications

Intratumoral heterogeneity (ITH) has been linked to decreased efficacy of clinical treatments. However, although genomic ITH has been characterized in genetic, transcriptomic and epigenetic alterations are hallmarks of esophageal squamous cell carcinoma (ESCC), the extent to which these are heterogeneous in ESCC has not been explored in a unified framework. Further, the extent to which tumor-infiltrated T lymphocytes are directed against cancer cells, but how the immune infiltration acts as a selective force to shape the clonal evolution of ESCC is unclear. In this study, we perform multi-omic sequencing on 186 samples from 36 primary ESCC patients. Through multi-omics analyses, …

Dual-Specificity Phosphatases 22-Deficient T Cells Contribute To The Pathogenesis Of Ankylosing Spondylitis, Ming-Han Chen, Huai-Chia Chuang, Yi-Chen Yeh, Chung-Tei Chou, Tse-Hua Tan

Children’s Nutrition Research Center Staff Publications

Background: Dual-specificity phosphatases (DUSPs) can dephosphorylate both tyrosine and serine/threonine residues of their substrates and regulate T cell-mediated immunity and autoimmunity. The aim of this study was to investigate the potential roles of DUSPs in ankylosing spondylitis (AS).

Methods: Sixty AS patients and 45 healthy controls were enrolled in this study. Associations of gene expression of 23 DUSPs in peripheral T cells with inflammatory cytokine gene expression and disease activity of AS were analyzed. Finally, we investigated whether the characteristics of AS are developed in DUSP-knockout mice.

Results: The mRNA levels of DUSP4, DUSP5, DUSP6, DUSP7, and DUSP14 in peripheral …

Children’s Nutrition Research Center Staff Publications

Objective: Lifestyle interventions have had limited effectiveness in work sites when evaluated in randomized trials. This study assessed the effectiveness of a novel lifestyle intervention for weight loss (Healthy Weight for Living [HWL]) implemented with or without meal replacements (MR) in work sites. HWL used a new behavioral approach emphasizing reducing hunger and building healthy food preferences, and, unlike traditional lifestyle interventions, it did not require calorie counting.

Methods: Twelve work sites were randomized to an 18-month intervention (n = 8; randomization within work sites to HWL, HWL + MR) or 6-month wait-listed control (n = 4). Participants were employees …

Diabetes Of Unclear Type In An Adolescent Boy With Multiple Islet-Cell Autoantibody Positivity Successfully Managed With Glucagon-Like Peptide-1 Receptor Agonist Alone: A Case Report, Olivia Z B Ginnard, Maria J Redondo, Sarah K Lyons

Children’s Nutrition Research Center Staff Publications

Diabetes classification has traditionally considered type 1 and type 2 diabetes as 2 separate entities with different pathogenic mechanisms. However, clinicians and researchers see increasingly more exceptions to this conventional paradigm, leading to a concept of mixed phenotypes in diabetes classification. Herein we report the case of an adolescent with unclear diabetes type due to the presence of obesity, robust endogenous insulin production, multiple islet autoantibody positivity and severe hyperglycemia at diabetes diagnosis that has been successfully treated with liraglutide therapy alone. Our case report highlights the difficulty of diabetes classification and subsequent need for personalized medicine with regard to …

Pgc-1Α Senses The Cbc Of Pre-Mrna To Dictate The Fate Of Promoter-Proximally Paused Rnapii, Xavier Rambout, Hana Cho, Roméo Blanc, Qing Lyu, Joseph M Miano, Joe V Chakkalakal, Geoffrey M Nelson, Hari K Yalamanchili, Karen Adelman, Lynne E Maquat

Children’s Nutrition Research Center Staff Publications

PGC-1α is well established as a metazoan transcriptional coactivator of cellular adaptation in response to stress. However, the mechanisms by which PGC-1α activates gene transcription are incompletely understood. Here, we report that PGC-1α serves as a scaffold protein that physically and functionally connects the DNA-binding protein estrogen-related receptor α (ERRα), cap-binding protein 80 (CBP80), and Mediator to overcome promoter-proximal pausing of RNAPII and transcriptionally activate stress-response genes. We show that PGC-1α promotes pausing release in a two-arm mechanism (1) by recruiting the positive transcription elongation factor b (P-TEFb) and (2) by outcompeting the premature transcription termination complex Integrator. Using mice …

Noninvasive Reflection Spectroscopy Measurement Of Skin Carotenoid Score In Infants Is Feasible And Reliable, Nancy E Moran, Jocelyn Chang, Rachel Stroh, Yusuf Zaidi, Noor Hason, Salma Musaad, Teresia O'Connor

Children’s Nutrition Research Center Staff Publications

Background: Skin carotenoid measurement by reflection spectroscopy (RS) offers a noninvasive biomarker of carotenoid intake, but feasibility, reliability, and validity are not established in infants.

Objectives: In this study we aimed to determine the feasibility and reliability of 4-mo-old infant skin carotenoid score (SCS) measurement and its correlation with total carotenoid intake and plasma concentrations.

Methods: SCSs were measured in a prospective, observational study with a modified, portable RS device at the index finger and heel of the foot in 4-mo-olds (n = 21). Infant plasma, human milk, and formula carotenoid concentrations were measured by HPLC-photodiode array, and carotenoid intake …

Only One Cluster Per Condition Is An Invalid Design For A Cluster Randomized Trial And Should Be Re-Labeled A Quasi-Experimental Study Response To: “Effect Of Behavioral Activation On Time And Frequency Domain Heart Rate Variability In Older Adults With Subthreshold Depression: A Cluster Randomized Controlled Trial In Thailand”, Yasaman Jamshidi-Naeini, Lilian Golzarri-Arroyo, Abu Bakkar Siddique, Colby J Vorland, David B Allison

Children’s Nutrition Research Center Staff Publications

Ayudhaya et al. examined the effect of Behavioral Activation on daily step count and heart rate variability among older adults with depression in a study labeled a cluster randomized controlled trial (cRCT). However, only one cluster was assigned to either of the study conditions. Such a design would have zero degrees of freedom for inferential testing, because the variation due to cluster membership cannot be estimated apart from the variation due to treatment assignment. Thus, the intervention effect is completely confounded with the cluster effect. The study should be labeled a quasi-experimental study, not a cRCT. Accordingly, the numerical results …

I2n: Image To Nutrients, A Sensor Guided Semi-Automated Tool For Annotation Of Images For Nutrition Analysis Of Eating Episodes, Tonmoy Ghosh, Megan A Mccrory, Tyson Marden, Janine Higgins, Alex Kojo Anderson, Christabel Ampong Domfe, Wenyan Jia, Benny Lo, Gary Frost, Matilda Steiner-Asiedu, Tom Baranowski, Mingui Sun, Edward Sazonov

Children’s Nutrition Research Center Staff Publications

Introduction: Dietary assessment is important for understanding nutritional status. Traditional methods of monitoring food intake through self-report such as diet diaries, 24-hour dietary recall, and food frequency questionnaires may be subject to errors and can be time-consuming for the user.

Methods: This paper presents a semi-automatic dietary assessment tool we developed - a desktop application called Image to Nutrients (I2N) - to process sensor-detected eating events and images captured during these eating events by a wearable sensor. I2N has the capacity to offer multiple food and nutrient databases (e.g., USDA-SR, FNDDS, USDA Global Branded Food Products Database) for annotating eating …

Relationship Between Reproductive And Bone Biomarkers And Osteoarthritis In Zoo Asian (Elephas Maximus) And African (Loxodonta Africana) Elephants, Daniella E Chusyd, Janine L Brown, Lilian Golzarri-Arroyo, Stephanie L Dickinson, Virginia B Kraus, Jessica Siegal-Willott, Timothy M Griffin, Janet L Huebner, Katie L Edwards, David B Allison, Steven N Austad

Children’s Nutrition Research Center Staff Publications

Osteoarthritis (OA) is common in zoo Asian (Elephas maximus) and African (Loxodonta africana) elephants. This study investigated the relationship between confirmed or suspected OA with ovarian cyclicity, gonadotropins, progestagens, luteinizing hormone (LH), follicular stimulating hormone (FSH), and collagen type I (CTX-I) in zoo elephants. In Asian elephants, odds of having confirmed or suspected OA decreased with cycling (OR = 0.22, P = 0.016; OR = 0.29, P = 0.020, respectively), however, not when adjusted for age (odds ratio [OR] = 0.31, P = 0.112; OR = 0.58, P = 0.369, respectively). In African elephants, none of …

Conditioning On Parental Mating Types Can Reduce Necessary Assumptions For Mendelian Randomization, Keisuke Ejima, Nianjun Liu, Luis Miguel Mestre, Gustavo De Los Campos, David B Allison

Children’s Nutrition Research Center Staff Publications

Mendelian randomization (MR) has become a common tool used in epidemiological studies. However, when confounding variables are correlated with the instrumental variable (in this case, a genetic/variant/marker), the estimation can remain biased even with MR. We propose conditioning on parental mating types (a function of parental genotypes) in MR to eliminate the need for one set of assumptions, thereby plausibly reducing such bias. We illustrate a situation in which the instrumental variable and confounding variables are correlated using two unlinked diallelic genetic loci: one, an instrumental variable and the other, a confounding variable. Assortative mating or population admixture can create …

Small Bowel Obstruction In Postpartum Vaginal Delivery Due To Prior Abdominal Adhesions Case Report, Liubin Yang, Lydia Kao

Children’s Nutrition Research Center Staff Publications

Intestinal obstruction rarely occurs after uncomplicated vaginal deliveries. Here, we present a case of a multiparous woman with a history of prior appendectomy presenting with generalized, nonspecific abdominal pain that was out of proportion to exam findings. Initial abdominal X-ray was nonspecific, and subsequent computed tomography (CT) abdomen showed closed small bowel obstruction requiring surgical repair. We present a case of intestinal obstruction occurring within 24 hours of uncomplicated vaginal delivery with a risk factor of a prior appendectomy surgery and the use of CT abdomen and pelvis to expedite diagnose.

Functional And Technical Outcomes In Acute Ischemic Stroke Patients With Hyperdense Middle Cerebral Artery Sign Treated With Endovascular Thrombectomy, Yimin Chen, Francesco Diana, Mohammad Mofatteh, Sijie Zhou, Juanmei Chen, Zhou Huang, Weijuan Wu, Yajie Yang, Zhiyi Zeng, Weijian Zhang, Ziqi Ouyang, Thanh N Nguyen, Shuiquan Yang, José Fidel Baizabal-Carvallo, Xuxing Liao

Children’s Nutrition Research Center Staff Publications

Background and objective: The hyperdense middle cerebral artery sign (HMCAS) is observed in a proportion of patients with acute ischemic stroke (AIS). This sign reflects the presence of an intravascular thrombus rich in red blood cells. Several studies have demonstrated that HMCAS increases the risk of poor outcomes in AIS patients treated with IV thrombolysis or no reperfusion therapy; however, whether HMCAS predicts a poor outcome in patients treated with endovascular thrombectomy (EVT) is less clear. We aimed to evaluate the functional outcome by the modified Rankin scale (mRS) at 90 days and technical challenges in patients with HMCAS undergoing …

A Conserved Oxalyl-Coenzyme A Decarboxylase In Oxalate Catabolism, Ninghui Cheng, Vincent Paris, Xiaolan Rao, Xiaoqiang Wang, Paul A Nakata

Children’s Nutrition Research Center Staff Publications

The ability to biosynthesize oxalic acid can provide beneficial functions to plants; however, uncontrolled or prolonged exposure to this strong organic acid results in multiple physiological problems. Such problems include a disruption of membrane integrity, mitochondrial function, metal chelation, and free radical formation. Recent work suggests that a CoA-dependent pathway of oxalate catabolism plays a critical role in regulating tissue oxalate concentrations in plants. Although this CoA-dependent pathway of oxalate catabolism is important, large gaps in our knowledge of the enzymes catalyzing each step remain. Evidence that an oxalyl-CoA decarboxylase (OXC) catalyzes the second step in this pathway, accelerating the …

Does Receiving A Sars-Cov-2 Antibody Test Result Change Covid-19 Protective Behaviors? Testing Risk Compensation In Undergraduate Students With A Randomized Controlled Trial, Christina Ludema, Molly S Rosenberg, Jonathan T Macy, Sina Kianersi, Maya Luetke, Chen Chen, Lilian Golzarri-Arroyo, Erin Ables, Kevin Maki, David B Allison

Children’s Nutrition Research Center Staff Publications

Background: Risk compensation, or matching behavior to a perceived level of acceptable risk, can blunt the effectiveness of public health interventions. One area of possible risk compensation during the SARS-CoV-2 pandemic is antibody testing. While antibody tests are imperfect measures of immunity, results may influence risk perception and individual preventive actions. We conducted a randomized control trial to assess whether receiving antibody test results changed SARS-CoV-2 protective behaviors.

Purpose: Assess whether objective information about antibody status, particularly for those who are antibody negative and likely still susceptible to SARS-CoV-2 infection, increases protective behaviors. Secondarily, assess whether a positive antibody test …

Depression is disabling and highly prevalent. Intravenous (IV) ketamine displays rapid-onset antidepressant properties, but little is known regarding which patients are most likely to benefit, limiting personalized prescriptions. We identified randomized controlled trials of IV ketamine that recruited individuals with a relevant psychiatric diagnosis (e.g., unipolar or bipolar depression; post-traumatic stress disorder), included one or more control arms, did not provide any other study-administered treatment in conjunction with ketamine (although clinically prescribed concurrent treatments were allowable), and assessed outcome using either the Montgomery-Åsberg Depression Rating Scale or the Hamilton Rating Scale for Depression (HRSD-17). Individual patient-level data for at least …

Complementary foods and beverages (CFBs) are key components of an infant’s diet in the second 6 months of life. This article summarizes nutrition and feeding practices examined by the 2020 Dietary Guidelines Advisory Committees during the CFB life stage. Breastfeeding initiation is high (84%), but exclusive breastfeeding at 6 months (26%) is below the Healthy People 2030 goal (42%). Most infants (51%) are introduced to CFBs sometime before 6 months. The primary mode of feeding (ie, human milk fed [HMF]; infant formula or mixed formula and human milk fed [FMF]) at the initiation of CFBs is associated with the timing …
