Although obesity is prevalent among children in the United States, pharmacokinetic (PK) data for obese children are limited. Clindamycin is a commonly used antibiotic that may require dose adjustment in obese children due to its lipophilic properties. We performed a clindamycin population PK analysis using data from three separate trials. A total of 420 samples from 220 children, 76 of whom had a body mass index greater than or equal to the 95th percentile for age, were included in the analysis. Compared to other metrics, total body weight (TBW) was the most robust measure of body size. The final model …

BACKGROUND: The genetic basis of dysfunctional immune responses in necrotizing enterocolitis (NEC) remains unknown. We hypothesized that variants in nucleotide binding and oligomerization domain (NOD)-like receptors (NLRs) and autophagy (ATG) genes modulate vulnerability to NEC.

METHODS: We genotyped a multi-center cohort of premature infants with and without NEC for NOD1, NOD2, ATG16L1, CARD8, and NLRP3 variants. Chi-square tests and logistic regression were used for statistical analysis.

RESULTS: In our primary cohort (n = 1,015), 86 (8.5%) infants developed NEC. The A allele of the ATG16L1 (Thr300Ala) variant was associated with increased NEC (AA vs. AG vs. GG; 11.3 vs. 8.4 …

The Texas Heart Institute Journal

The efficacy of pulmonary vein antral isolation for patients with prolonged sinus pauses (PSP) on termination of atrial fibrillation has been reported. We studied the right atrial (RA) electrophysiologic and electroanatomic characteristics in such patients.

Forty patients underwent electroanatomic mapping of the RA: 13 had PSP (group A), 13 had no PSP (group B), and 14 had paroxysmal supraventricular tachycardia (control group C). Group A had longer P-wave durations in lead II than did groups B and C (115.5 ± 15.4 vs 99.5 ± 10.9 vs 96.5 ± 10.4 ms; P=0.001), and RA activation times (106.8 ± 13.8 vs …

Nina Braunwald: A Female Pioneer In Cardiac Surgery, Nikhil Sabharwal, Harmanjit Dev, Hassiba Smail, David C Mcgiffin, Pankaj Saxena

The Texas Heart Institute Journal

Nina Starr Braunwald, the first female cardiac surgeon, made headlines during a time when almost all specialty surgeons were men.

Women have typically been deterred from entering surgical specialties, in part because of their traditional dual burden of managing their households and careers. Instead, female medical students and junior doctors have tended to be more attracted to medical specialties. This was the reality during Dr. Braunwald's venture into medicine in 1949. However, she never allowed negative ideas to keep her from joining a surgical training program.

Under the mentorship of the prominent cardiac surgeons Charles Hufnagel and Andrew Morrow, Dr. …

Transcatheter Aortic Valve Implantation In A Patient With Unicuspid Aortic Valve, Angelo Nascimbene, Pranav Loyalka, Igor D Gregoric, Ricardo Bellera, Maan Malahfji, Marija Petrovic, Biswajit Kar

The Texas Heart Institute Journal

Transcatheter aortic valve replacement (TAVR) in patients with bicuspid aortic valves has been successfully performed, but there is a lack of published experience in percutaneous treatment of patients with unicuspid valves and severe aortic stenosis. We describe a case of TAVR in such a patient.

A 31-year-old woman with Turner syndrome—who had undergone coarctation repair via subclavian flap at age 7 days and an aortic valvotomy at age 6 weeks—presented with severe symptomatic aortic stenosis. She was deemed inoperable because of her severe pulmonary hypertension and numerous comorbidities; consequently, a 20-mm Edwards Sapien 3 Transcatheter Heart Valve was offered for …

Methods To Decrease Variability In Histological Scoring In Placentas From A Cohort Of Preterm Infants, Jennifer K. Straughen, Dawn P. Misra, Linda M. Ernst, Adrian K. Charles, Samantha Vanhorn, Samiran Ghosh, Irina Buhimschi, Catalin Buhimschi, George Divine, Carolyn M. Salafia

Public Health Sciences Articles

OBJECTIVE: Reliable semiquantitative assessment of histological placental acute inflammation is problematic, even among experts. Tissue samples in histology slides often show variability in the extent and location of neutrophil infiltrates. We sought to determine whether the variability in pathologists' scoring of neutrophil infiltrates in the placenta could be reduced by the use of 'regions of interest' (ROIs) that break the sample into smaller components.

DESIGN: ROIs were identified within stained H&E slides from a cohort of 56 women. ROIs were scored using a semiquantitative scale (0-4) for the average number of neutrophils by at least two independent raters.

SETTING: Preterm …

GabaB Receptor Attenuation Of GabaA Currents In Neurons Of The Mammalian Central Nervous System, Wen Shen, Changlong Nan, Peter T. Nelson, Harris Ripps, Malcolm M. Slaughter

Pathology and Laboratory Medicine Faculty Publications

Ionotropic receptors are tightly regulated by second messenger systems and are often present along with their metabotropic counterparts on a neuron's plasma membrane. This leads to the hypothesis that the two receptor subtypes can interact, and indeed this has been observed in excitatory glutamate and inhibitory GABA receptors. In both systems the metabotropic pathway augments the ionotropic receptor response. However, we have found that the metabotropic GABA_B receptor can suppress the ionotropic GABA_A receptor current, in both the in vitro mouse retina and in human amygdala membrane fractions. Expression of amygdala membrane microdomains in Xenopus oocytes by microtransplantation …

Neutralizing Anti-Interleukin-1Β Antibodies Reduce Ischemia-Related Interleukin-1Β Transport Across The Blood-Brain Barrier In Fetal Sheep, Aparna Patra, Xiaodi Chen, Grazyna B. Sadowska, Jiyong Zhang, Yow-Pin Lim, James F. Padbury, William A. Banks, Barbara S. Stonestreet

Pediatrics Faculty Publications

Hypoxic ischemic insults predispose to perinatal brain injury. Pro-inflammatory cytokines are important in the evolution of this injury. Interleukin-1β (IL-1β) is a key mediator of inflammatory responses and elevated IL-1β levels in brain correlate with adverse neurodevelopmental outcomes after brain injury. Impaired blood-brain barrier (BBB) function represents an important component of hypoxic-ischemic brain injury in the fetus. In addition, ischemia-reperfusion increases cytokine transport across the BBB of the ovine fetus. Reducing pro-inflammatory cytokine entry into brain could represent a novel approach to attenuate ischemia-related brain injury. We hypothesized that infusions of neutralizing IL-1β monoclonal antibody (mAb) reduce IL-1β transport across …

Metabolic And Molecular Insights Into An Essential Role Of Nicotinamide Phosphoribosyltransferase., Li Q. Zhang, Leon Van Haandel, Min Xiong, Peixin Huang, Daniel P. Heruth, Chengpeng Bi, R Gaedigk, Xun Jiang, Ding-You Li, Gerald Wyckoff, Dmitry N. Grigoryev, Li Gao, Linheng Li, Min Wu, J Steven Leeder, Shui Qing Ye

Manuscripts, Articles, Book Chapters and Other Papers

Nicotinamide phosphoribosyltransferase (NAMPT) is a pleiotropic protein implicated in the pathogenesis of acute respiratory distress syndrome, aging, cancer, coronary heart diseases, diabetes, nonalcoholic fatty liver disease, obesity, rheumatoid arthritis, and sepsis. However, the underlying molecular mechanisms of NAMPT in these physiological and pathological processes are not fully understood. Here, we provide experimental evidence that a Nampt gene homozygous knockout (Nampt-/-) resulted in lethality at an early stage of mouse embryonic development and death within 5-10 days in adult mice accompanied by a 25.24±2.22% body weight loss, after the tamoxifen induction of NamptF/F × Cre mice. These results substantiate that Nampt …

Lactate Dehydrogenase In Toxoplasma Gondii Controls Virulence, Bradyzoite Differentiation, And Chronic Infection, Abdelbaset E. Abdelbaset, Barbara A. Fox, Mohamed H. Karram, Mahmoud R. Abd Ellah, David J. Bzik, Makoto Igarashi

Dartmouth Scholarship

In the asexual stages, Toxoplasma gondii stage converts between acute phase rapidly replicating tachyzoites and chronic phase slowly dividing bradyzoites. Correspondingly, T. gondii differentially expresses two distinct genes and isoforms of the lactate dehydrogenase enzyme, expressing LDH1 exclusively in the tachyzoite stage and LDH2 preferentially in the bradyzoite stage. LDH catalyzes the interconversion of pyruvate and lactate in anaerobic growth conditions and is utilized for energy supply, however, the precise role of LDH1 and LDH2 in parasite biology in the asexual stages is still unclear. Here, we investigated the biological role of LDH1 and LDH2 in the asexual stages, …

Lactational Stage Of Pasteurized Human Donor Milk Contributes To Nutrient Limitations For Infants., Christina J Valentine, Georgia Morrow, Amanda Reisinger, Kelly A Dingess, Ardythe L Morrow, Lynette K Rogers

Women’s Health Articles

BACKGROUND: Mother's own milk is the first choice for feeding preterm infants, but when not available, pasteurized human donor milk (PDM) is often used. Infants fed PDM have difficulties maintaining appropriate growth velocities. To assess the most basic elements of nutrition, we tested the hypotheses that fatty acid and amino acid composition of PDM is highly variable and standard pooling practices attenuate variability; however, total nutrients may be limiting without supplementation due to late lactational stage of the milk.

METHODS: A prospective cross-sectional sampling of milk was obtained from five donor milk banks located in Ohio, Michigan, Colorado, Texas-Ft Worth, …

High-Fat Feeding Does Not Disrupt Daily Rhythms In Female Mice Because Of Protection By Ovarian Hormones, Brian T. Palmisano, John M. Stafford, Julie S. Pendergast

Biology Faculty Publications

Obesity in women is increased by the loss of circulating estrogen after menopause. Shift work, which disrupts circadian rhythms, also increases the risk for obesity. It is not known whether ovarian hormones interact with the circadian system to protect females from obesity. During high-fat feeding, male C57BL/6J mice develop profound obesity and disruption of daily rhythms. Since C57BL/6J female mice did not develop diet-induced obesity (during 8 weeks of high-fat feeding), we first determined if daily rhythms in female mice were resistant to disruption from high-fat diet. We fed female PERIOD2:LUCIFERASE mice 45% high-fat diet for 1 week and measured …

Medical Biophysics Publications

CT biomarkers of emphysema (15th percentile of the CT density histogram, HU15%) and airways disease (wall thickness of airways with 10 mm internal perimeter, Pi10) have shown promise for providing prognostic information.2 Although recent data3 showed that the change in CT emphysema may be used to estimate the efficacy of therapy in patients with α-1-antitrypsin-deficiency, thus far none of the currently developed CT biomarkers have been shown to reflect changes in outcomes that are important to patients with COPD. MRI with inhaled noble gases provide highly sensitive and unique microstructural and functional information in COPD.4 MRI biomarkers of COPD are …

Using A Respiratory Navigator Significantly Reduces Variability When Quantifying Left Ventricular Torsion With Cardiovascular Magnetic Resonance, Sean M. Hamlet, Christopher M. Haggerty, Jonathan D. Suever, Gregory J. Wehner, Kristin N. Andres, David K. Powell, Richard J. Charnigo, Brandon K. Fornwalt

Electrical and Computer Engineering Faculty Publications

Background: Left ventricular (LV) torsion is an important indicator of cardiac function that is limited by high inter-test variability (50% of the mean value). We hypothesized that this high inter-test variability is partly due to inconsistent breath-hold positions during serial image acquisitions, which could be significantly improved by using a respiratory navigator for cardiovascular magnetic resonance (CMR) based quantification of LV torsion.

Methods: We assessed respiratory-related variability in measured LV torsion with two distinct experimental protocols. First, 17 volunteers were recruited for CMR with cine displacement encoding with stimulated echoes (DENSE) in which a respiratory navigator was used to measure …

Indicators Of Cognitive Impairment From A Medical Record Review: Correlations With Early (30-D) Readmissions Among Hospitalized Patients In A Nephrology Unit, Matthew J. Jasinski, Mark A. Lumley, Sandeep Soman, Jerry Yee, Mark W. Ketterer

Nephrology Articles

BACKGROUND: Patients with end-stage renal disease have the highest 30-day hospital readmission rates of any medical condition. Previous research suggests that cognitive impairment contributes to readmission. It is important to identify patients at risk for early readmission, and this might be accomplished efficiently using medical record data.

METHOD: We reviewed the medical records of 100 patients with kidney disease (57 women, mean age = 61.2) who were hospitalized in the nephrology unit at an urban U.S. hospital. For each patient, we recorded easily available indicators of cognitive impairment along with other potential risk factors, and also recorded the number of …

Respiratory Syncytial Virus Hospitalization Risk In The Second Year Of Life By Specific Congenital Heart Disease Diagnoses, Deborah Friedman, J Fryzek, X Jiang, A Bloomfield, C Ambrose, P Wong

NYMC Faculty Publications

Children with hemodynamically significant congenital heart disease (CHD) are at elevated risk of morbidity and mortality due to respiratory syncytial virus (RSV) disease compared to their healthy peers. Previous studies have demonstrated lower RSV hospitalization risk among all children with CHD at 12-23 months of age versus 0-11 months of age. However, RSV hospitalization risk at 12-23 months of age by specific CHD diagnosis has not been characterized. Both case-control and cohort studies were conducted using data from the US National Inpatient Sample from 1997 to 2013 to characterize relative risk of RSV hospitalization among children 12-23 months of age …

Cytomegalovirus Serostatus, Inflammation, And Antibody Response To Influenza Vaccination In Older Adults: The Moderating Effect Of Beta Blockade, Rebecca G. Reed, Richard N. Greenberg, Suzanne C. Segerstrom

Integrated Biomarker Profiling Of Smokers With Periodontitis, Radhakrishnan Nagarajan, Mohanad Al-Sabbagh, Dolph Dawson Iii, Jeffrey L. Ebersole

Institute for Biomedical Informatics Faculty Publications

Background

In the context of precision medicine, understanding patient‐specific variation is an important step in developing targeted and patient‐tailored treatment regimens for periodontitis. While several studies have successfully demonstrated the usefulness of molecular expression profiling in conjunction with single classifier systems in discerning distinct disease groups, the majority of these studies do not provide sufficient insights into potential variations within the disease groups.

Aim

The goal of this study was to discern biological response profiles of periodontitis and non‐periodontitis smoking subjects using an informed panel of biomarkers across multiple scales (salivary, oral microbiome, pathogens and other markers).

Oral Cannabidiol Does Not Produce A Signal For Abuse Liability In Frequent Marijuana Smokers, Shanna Babalonis, Margaret Haney, Robert J. Malcolm, Michelle R. Lofwall, Victoria R. Votaw, Steven Sparenborg, Sharon L. Walsh

Behavioral Science Faculty Publications

Background—Cannabidiol (CBD) is a naturally occurring constituent of the marijuana plant. In the past few years, there has been great interest in the therapeutic effects of isolated CBD and it is currently being explored for numerous disease conditions (e.g., pain, epilepsy, cancer, various drug dependencies). However, CBD remains a Schedule I drug on the U.S. Controlled Substances Act (CSA). Despite its status, there are no well-controlled data available regarding its abuse liability.

Methods—Healthy, frequent marijuana users (n=31) were enrolled in this within subject, randomized, placebo-controlled, double-blind, multisite study that administered oral cannabidiol (0, 200, 400, 800 …

Faster Self-Paced Rate Of Drinking For Alcohol Mixed With Energy Drinks Versus Alcohol Alone, Cecile A. Marczinski, Mark T. Fillmore, Sarah F. Maloney, Amy L. Stamates

Psychology Faculty Publications

The consumption of alcohol mixed with energy drinks (AmED) has been associated with higher rates of binge drinking and impaired driving when compared with alcohol alone. However, it remains unclear why the risks of use of AmED are heightened compared with alcohol alone even when the doses of alcohol consumed are similar. Therefore, the purpose of this laboratory study was to investigate if the rate of self-paced beverage consumption was faster for a dose of AmED versus alcohol alone using a double-blind, within-subjects, placebo-controlled study design. Participants (n = 16) of equal gender who were social drinkers attended 4 separate …
