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.

Metabolomic Markers Of Ultra-Processed Food And Incident Ckd, Donghan Su, Jingsha Chen, Shutong Du, Hyunju Kim, Bing Yu, Kari E Wong, Eric Boerwinkle, Casey M Rebholz

Faculty, Staff and Student Publications

BACKGROUND: High ultra-processed food consumption is associated with higher risk of CKD. However, there is no biomarker for ultra-processed food, and the mechanism through which ultra-processed food is associated with CKD is not clear. Metabolomics can provide objective biomarkers of ultra-processed food and provide important insights into the mechanisms by which ultra-processed food is associated with risk of incident CKD. Our objective was to identify serum metabolites associated with ultra-processed food consumption and investigate whether ultra-processed food-associated metabolites are prospectively associated with incident CKD.

METHODS: We used data from 3751 Black and White men and women (aged 45-64 years) in …

Asprosin Promotes Feeding Through Sk Channel-Dependent Activation Of Agrp Neurons, Bing Feng, Hesong Liu, Ila Mishra, Clemens Duerrschmid, Peiyu Gao, Pingwen Xu, Chunmei Wang, Yanlin He

Faculty, Staff and Students Publications

Asprosin, a recently identified adipokine, activates agouti-related peptide (AgRP) neurons in the arcuate nucleus of the hypothalamus (ARH) via binding to protein tyrosine phosphatase receptor δ (Ptprd) to increase food intake. However, the intracellular mechanisms responsible for asprosin/Ptprd-mediated activation of AgRPARH neurons remain unknown. Here, we demonstrate that the small-conductance calcium-activated potassium (SK) channel is required for the stimulatory effects of asprosin/Ptprd on AgRPARH neurons. Specifically, we found that deficiency or elevation of circulating asprosin increased or decreased the SK current in AgRPARH neurons, respectively. AgRPARH-specific deletion of SK3 (an SK channel subtype highly expressed in AgRPARH neurons) blocked asprosin-induced …

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, …

How Much Did It Cost To Develop And Implement An Ehealth Intervention For A Minority Children Population That Overlapped With The Covid-19 Pandemic?, Alexandra Monashefsky, Dar Alon, Tom Baranowski, Tiago V Barreira, Kelly A Chiu, Amy Fleischman, Melanie C Green, Shirley Huang, Ronald C Samuels, Caio Victor Sousa, Debbe Thompson, Amy S Lu

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 …

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 …

Increased Camkk2 Expression Is An Adaptive Response That Maintains The Fitness Of Tumor-Infiltrating Natural Killer Cells, Patrick K Juras, Luigi Racioppi, Debarati Mukherjee, Sandeep Artham, Xia Gao, Laura Akullian D'Agostino, Ching-Yi Chang, Donald P Mcdonnell

Faculty, Staff and Students Publications

Calcium/calmodulin-dependent protein kinase kinase 2 (CaMKK2) is a key regulator of energy homeostasis in several cell types. Expression of this enzyme in tumor cells promotes proliferation and migration, and expression in tumor-associated immune cells facilitates M2 macrophage polarization and the development of myeloid-derived suppressor cells. Thus, there has been interest in developing CaMKK2 inhibitors as potential anticancer therapeutics. One impediment to clinical development of these agents is that the roles of CaMKK2 in other cellular compartments within the tumor immune microenvironment remain to be established. We report herein that CaMKK2 is expressed at low basal levels in natural killer (NK) …

Sex-Specific Associations Between Urinary Bisphenols Concentrations During Pregnancy And Problematic Child Behaviors At Age 2 Years, Sarah Dee Geiger, Salma Musaad, Jennifer Hill, Andréa Aguiar, Susan Schantz

Faculty, Staff and Students Publications

Effects of prenatal bisphenol A (BPA) exposure on child behavior are mixed with some reports suggesting increased problematic behaviors in girls (e.g., aggression and emotional reactivity) and in boys (i.e., externalizing behaviors), while other reports suggest decreased problematic behaviors in girls. Little is known about the potential impact of pregnancy bisphenol S (BPS) exposure on child behavior. In a prospective cohort study (n=68), five maternal spot urine samples collected across pregnancy were pooled and analyzed for BPA and BPS. Child behavior at 2 years was assessed using the Child Behavior Checklist (CBCL). Linear regression models were used to assess associations …

Initial Insights Into The Genetic Variation Associated With Metformin Treatment Failure In Youth With Type 2 Diabetes, Shylaja Srinivasan, Ling Chen, Miriam Udler, Jennifer Todd, Megan M Kelsey, Morey W Haymond, Silva Arslanian, Philip Zeitler, Rose Gubitosi-Klug, Kristen J Nadeau, Katherine Kutney, Neil H White, Josephine H Li, James A Perry, Varinderpal Kaur, Laura Brenner, Josep M Mercader, Adem Dawed, Ewan R Pearson, Sook-Wah Yee, Kathleen M Giacomini, Toni Pollin, Jose C Florez

Metformin is the first-line treatment for type 2 diabetes (T2D) in youth but with limited sustained glycemic response. To identify common variants associated with metformin response, we used a genome-wide approach in 506 youth from the Treatment Options for Type 2 Diabetes in Adolescents and Youth (TODAY) study and examined the relationship between T2D partitioned polygenic scores (pPS), glycemic traits, and metformin response in these youth. Several variants met a suggestive threshold (P < 1 × 10−6), though none including published adult variants reached genome-wide significance. We pursued replication of top nine variants in three cohorts, and rs76195229 in ATRNL1 was associated with worse metformin response in the Metformin Genetics Consortium (n = 7,812), though statistically not being significant after Bonferroni correction (P …

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 …

Investigators traditionally use randomized designs and corresponding analysis procedures to make causal inferences about the effects of interventions, assuming independence between an individual's outcome and treatment assignment and the outcomes of other individuals in the study. Often, such independence may not hold. We provide examples of interdependency in model organism studies and human trials and group effects in aging research and then discuss methodologic issues and solutions. We group methodologic issues as they pertain to (1) single-stage individually randomized trials; (2) cluster-randomized controlled trials; (3) pseudo-cluster-randomized trials; (4) individually randomized group treatment; and (5) two-stage randomized designs. Although we present …

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 …

Serotonin reuptake inhibitors and receptor agonists are used to treat obesity, anxiety and depression. Here we studied the role of the serotonin 2C receptor (5-HT2CR) in weight regulation and behavior. Using exome sequencing of 2,548 people with severe obesity and 1,117 control individuals without obesity, we identified 13 rare variants in the gene encoding 5-HT2CR (HTR2C) in 19 unrelated people (3 males and 16 females). Eleven variants caused a loss of function in HEK293 cells. All people who carried variants had hyperphagia and some degree of maladaptive behavior. Knock-in male mice harboring a human loss-of-function HTR2C variant developed …

Water is essential for survival, but one in three individuals worldwide (2.2 billion people) lack access to safe drinking water. Water intake requirements largely reflect water turnover (WT), the water used by the body each day. We investigated the determinants of human WT in 5,604 people from the ages of 8 days to 96 years from 26 countries using isotope tracking (2H) methods. Age, body size, and composition were significantly associated with WT as were physical activity, athletic status, pregnancy, socioeconomic status, and environmental characteristics (latitude, altitude, air temperature, and humidity). People in countries with low human development index (HDI) …
