Ambulatory and Primary Care Articles

BACKGROUND: The Global Leadership Initiative on Malnutrition (GLIM) approach to malnutrition diagnosis is based on assessment of three phenotypic (weight loss, low body mass index, and reduced skeletal muscle mass) and two etiologic (reduced food intake/assimilation and disease burden/inflammation) criteria, with diagnosis confirmed by fulfillment of any combination of at least one phenotypic and at least one etiologic criterion. The original GLIM description provided limited guidance regarding assessment of inflammation, and this has been a factor impeding further implementation of the GLIM criteria. We now seek to provide practical guidance for assessment of inflammation.

METHODS: A GLIM-constituted working group with …

Endolysosomal Trafficking Controls Yolk Granule Biogenesis In Vitellogenic Drosophila Oocytes, Yue Yu, Dongsheng Chen, Stephen M Farmer, Shiyu Xu, Beatriz Rios, Amanda Solbach, Xin Ye, Lili Ye, Sheng Zhang

Faculty, Staff and Student Publications

Endocytosis and endolysosomal trafficking are essential for almost all aspects of physiological functions of eukaryotic cells. As our understanding on these membrane trafficking events are mostly from studies in yeast and cultured mammalian cells, one challenge is to systematically evaluate the findings from these cell-based studies in multicellular organisms under physiological settings. One potentially valuable in vivo system to address this challenge is the vitellogenic oocyte in Drosophila, which undergoes extensive endocytosis by Yolkless (Yl), a low-density lipoprotein receptor (LDLR), to uptake extracellular lipoproteins into oocytes and package them into a specialized lysosome, the yolk granule, for storage and usage …

Azithromycin Reduces Hemoglobin-Induced Innate Neuroimmune Activation, Chirayu D Pandya, Hemendra J Vekaria, Miriam Zamorano, Amanda L Trout, Rodney M Ritzel, Gary U Guzman, Christopher Bolden, Patrick G Sullivan, John C Gensel, Brandon A Miller

Faculty, Staff and Student Publications

Neonatal intraventricular hemorrhage (IVH) releases blood products into the lateral ventricles and brain parenchyma. There are currently no medical treatments for IVH and surgery is used to treat a delayed effect of IVH, post-hemorrhagic hydrocephalus. However, surgery is not a cure for intrinsic brain injury from IVH, and is performed in a subacute time frame. Like many neurological diseases and injuries, innate immune activation is implicated in the pathogenesis of IVH. Innate immune activation is a pharmaceutically targetable mechanism to reduce brain injury and post-hemorrhagic hydrocephalus after IVH. Here, we tested the macrolide antibiotic azithromycin, which has immunomodulatory properties, to …

Cognitive Reserve In Individuals With Frontotemporal Dementia And Primary Progressive Aphasia, Lauren A. Grebe

Dissertations, Theses, and Capstone Projects

Cognitive reserve refers to the brain’s ability to efficiently adapt in the presence of neuropathological disease. This is an active process influenced by individual differences (e.g., genetics) and lifetime experiences (e.g., education, occupation, leisure) (Cabeza et al., 2018; Stern et al., 2020). The cognitive reserve theory has recently been investigated in individuals with frontotemporal dementia (FTD), which refers to various disorders leading to frontotemporal neurodegenerative decline (Young et al., 2018); e.g., behavioral variant of FTD (bvFTD) and variants of Primary Progressive Aphasia (PPA): semantic (svPPA), nonfluent/agrammatic (nfvPPA), and logopenic (lvPPA). However, a clear consensus on the relationship among cognitive reserve, …

INTRODUCTION: Optimal venous thromboembolism (VTE) enoxaparin prophylaxis dosing remains elusive. Weight-based (WB) dosing safely increases anti-factor Xa levels without the need for routine monitoring but it is unclear if it leads to lower VTE risk. We hypothesized that WB dosing would decrease VTE risk compared with standard fixed dosing (SFD).

METHODS: Patients from the prospective, observational CLOTT-1 registry receiving prophylactic enoxaparin (n=5539) were categorized as WB (0.45-0.55 mg/kg two times per day) or SFD (30 mg two times per day, 40 mg once a day). Multivariate logistic regression was used to generate a predicted probability of VTE for WB and …

Advances in surgical technique and multidisciplinary management have improved long-term survival for patients born with single ventricle physiology. However, patients who have undergone Fontan completion remain at risk for long-term comorbidities associated with the complex hemodynamic changes following the procedure, including Fontan failure and Fontan-associated liver disease.1 Combined heart-liver transplantation (CHLT) is a rare but lifesaving procedure that has been described in the setting of heart and liver failure secondary to Fontan failure.2 As long-term survival continues to improve for Fontan patients, the incidence of Fontan-associated liver disease will increase. Thus, improving CHLT outcomes and access to both …

Metaphyseal Fracture Displacement Is Predictive Of Intra-Articular Diastasis In Adolescent Triplane Ankle Fractures, Dustin A Greenhill, Surya N Mundluru, Robert W Gomez, Joseph Romero, Anthony I Riccio

Faculty, Staff and Student Publications

Background: Triplane fractures are rare enough that large homogeneous series to support management decisions are lacking. During initial evaluation, the addition of computed tomography (CT) to conventional X-rays (XR) does not always alter the patient's clinical course. Therefore, routine use of CT is controversial. This study aims to: (1) clarify quantitative relationships between articular displacement measured on XR versus CT and (2) identify whether metaphyseal displacement on the lateral XR predicts clinically relevant articular displacement on a CT scan.

Methods: A 10-year retrospective review of consecutive triplane fractures was performed at a level 1 pediatric trauma center. Maximum articular and …

Pulmonary Alveolar Microlithiasis In A Middle-Aged Man Presenting With Respiratory Failure: A Case Report And Review Of The Literature, Allen C Omo-Ogboi, Joyce Ederhion, Asad Ur Rehman, Olanrewaju Ogunleye, Jaiyeola Thomas-Ogunniyi

Faculty, Staff and Student Publications

Pulmonary alveolar microlithiasis (PAM) is an autosomal recessive disease of the lung, characterized by diffuse deposits of intra-alveolar calcium phosphate microliths. It usually affects both sexes, presenting mostly in the second and third decades. The clinical course is highly variable, ranging from being asymptomatic to respiratory failure. PAM is usually diagnosed after careful clinical, radiological, and pathological evaluation, usually when patients present for other medical purposes. Here, a case of PAM in a middle-aged man presenting with acute-on-chronic hypoxemic respiratory failure is reported, with a review of the literature.

Objectives: To describe the epidemiology of BSI in the year after several types of SOT, as well as the prevalence of MDRO infections in this population.

Methods: We conducted a single-centre, retrospective study of kidney, liver, heart, and multi-organ transplantation patients. We examined BSIs ≤1 year from SOT and classified MDRO phenotypes for Staphylococcus aureus, enterococci, Enterobacterales, Pseudomonas aeruginosa and Candida spp. We compared BSI characteristics between SOT types and determined risk factors for 90 day mortality.

Results: We included 2293 patients …

Does Coding Internal Working Models Of Attachment Have To Be So Hard?, Amanda Venta, Veronica Mclaren, Carla Sharp, Anna Abate, Madeleine Allman, Breana Cervantes, Sophie Kerr, Jessica Hernandez Ortiz, Eric Sumlin, Jesse Walker, Kiana Wall

Faculty, Staff and Student Publications

The Child Attachment Interview (CAI) has demonstrated promise in youth, yet widespread use is thwarted by the need for interview transcription, face-to-face training, and reliability certification. The present study sought to examine the empirical basis for these barriers. Thirty-five archival CAIs were re-coded by: (1) expert coders (i.e., trained and reliable) without access to transcripts, (2) trained coders who had not completed reliability training, and (3) novice coders who had no formal training. Agreement with consensus classifications was computed with the expectation of moderate agreement. Results supported coding by experts without transcription of the interview. Near-moderate agreement preliminarily supported the …

Girth-Based Administered Activity For Pediatric 99mtc-Dmsa Spect, Ye Li, Justin L Brown, Jingyan Xu, Junyu Chen, Michael Ghaly, Monet Dugan, Xinhua Cao, Yong Du, Frederic H Fahey, Wesley Bolch, George Sgouros, Eric C Frey

Faculty, Staff and Student Publications

Background: Pediatric molecular imaging requires a balance between administering an activity that will yield sufficient diagnostic image quality while maintaining patient radiation exposure at acceptable levels. In current clinical practice, this balance is arrived at by the current North American Consensus Guidelines in which patient weight is used to recommend the administered activity (AA).

Purpose: We have previously demonstrated that girth (waist circumference at the level of the kidneys) is better at equalizing image quality than patient weight for pediatric Tc-99m DMSA renal function imaging. However, the correlation between image quality (IQ), AA, and patient girth has not been rigorously …

BACKGROUND: Achieving an optimal shade match for these restorations is crucial for aesthetic outcomes. The thickness of zirconia/glass veneer and the choice of implant abutment material play vital roles in determining the final shade of implant restorations.

MATERIALS AND METHODS: This study investigated the influence of zirconia/glass veneer thickness (0.5 mm and 1.0 mm) and implant abutment material (zirconia and titanium) on the final shade of implant restorations. A total of 60 identical implant restorations were fabricated and divided into four groups based on the combinations of veneer thickness and abutment material. The shade of each restoration was assessed using …

Risk Factors For Post-Discharge Adverse Outcomes Following Hospitalization Among Older Adults Diagnosed With Elder Mistreatment, Monique R Pappadis, Leila Wood, Allen Haas, Jordan Westra, Yong-Fang Kuo, Charles P Mouton

Faculty, Staff and Student Publications

Using 100% Medicare data files, this study explored whether primary elder mistreatment (EM) diagnosis, EM type, and facility type were associated with 3-year mortality and 1-year unplanned hospital readmission among older patients diagnosed with EM with hospital discharge from 10/01/2015 through 12/31/2018 (n = 11,023). We also examined outcome differences between older patients diagnosed with EM and matched non-EM patient controls. Neglect by others was the most common EM diagnosis. Three-year mortality was 56.7% and one-year readmission rate was 53.8%. Compared to matched non-EM patient controls, older EM patients were at an increased risk of mortality and readmission. Among …

Glomerular diseases are classified using a descriptive taxonomy that is not reflective of the heterogeneous underlying molecular drivers. This limits not only diagnostic and therapeutic patient management, but also impacts clinical trials evaluating targeted interventions. The Nephrotic Syndrome Study Network (NEPTUNE) is poised to address these challenges. The study has enrolled >850 pediatric and adult patients with proteinuric glomerular diseases who have contributed to deep clinical, histologic, genetic, and molecular profiles linked to long-term outcomes. The NEPTUNE Knowledge Network, comprising combined, multiscalar data sets, captures each participant's molecular disease processes at the time of kidney biopsy. In this editorial, we …

Large-Scale Investigation Of White Matter Structural Differences In Bilingual And Monolingual Children: An Adolescent Brain Cognitive Development Data Study, Juliana Ronderos, Jennifer Zuk, Arturo E Hernandez, Kelly A Vaughn

Faculty, Staff and Student Publications

Emerging research has provided valuable insights into the structural characteristics of the bilingual brain from studies of bilingual adults; however, there is a dearth of evidence examining brain structural alterations in childhood associated with the bilingual experience. This study examined the associations between bilingualism and white matter organization in bilingual children compared to monolingual peers leveraging the large-scale data from the Adolescent Brain Cognitive Development (ABCD) Study. Then, 446 bilingual children (ages 9-10) were identified from the participants in the ABCD data and rigorously matched to a group of 446 monolingual peers. Multiple regression models for selected language and cognitive …

Faculty, Staff and Students Publications

Sickle cell disease is a condition that can involve numerous organ systems secondary to vascular occlusion. Herein, we present a case of a 21-year-old male with sickle cell disease requiring long-term hydroxyurea therapy. Upon migrating to the United States from Yemen, the patient developed a rapidly progressive, exquisitely painful ulcer on his right lower extremity. Given his country of origin, a broad differential, including select infectious diseases, was essential. Moreover, establishing the unequivocally correct diagnosis was crucial to determine proper and safe therapy. Ultimately, a lesional biopsy demonstrated numerous sickled red blood cells occluding blood vessels, leading to the diagnosis …

Idiopathic pulmonary fibrosis (IPF) is a progressive and fatal interstitial lung disease of unknown etiology. The emerging evidence demonstrates that metabolic homeostatic imbalance caused by repetitive injuries of the alveolar epithelium is the potential pathogenesis of IPF. Proteomic analysis identified that Acetyl-CoA synthetase short chain family member 3 (ACSS3) expression was decreased in IPF patients and mice with bleomycin-induced fibrosis. ACSS3 participated in lipid and carbohydrate metabolism. Increased expression of ACSS3 downregulated carnitine palmitoyltransferase 1A (CPT-1A) and resulted in the accumulation of lipid droplets, while enhanced glycolysis which led to an increase in extracellular lactic acid levels in A549 cells. …

Biophysical And Biochemical Characterization Of A Recombinant Lyme Disease Vaccine Antigen, Cspz-Ya, Yi-Lin Chen, Jungsoon Lee, Zhuyun Liu, Ulrich Strych, Maria Elena Bottazzi, Yi-Pin Lin, Wen-Hsiang Chen

Faculty, Staff and Students Publications

Lyme disease, caused by Lyme Borrelia spirochetes, is the most common vector-borne illness in the United States. Despite its global significance, with an estimated 14.5 % seroprevalence, there is currently no licensed vaccine. Previously, we demonstrated that CspZ-YA protein conferred protection against Lyme Borrelia infection, making it a promising vaccine candidate. However, such a protein was tagged with hexahistidine, and thus not preferred for vaccine development; furthermore, the formulation to stabilize the protein was understudied. In this work, we developed a two-step purification process for tag-free E. coli-expressed recombinant CspZ-YA. We further utilized various bioassays to analyze the protein and …

Background: Smoking impacts DNA methylation, but data are lacking on smoking-related differential methylation by sex or dietary intake, recent smoking cessation (< 1 year), persistence of differential methylation from in utero smoking exposure, and effects of environmental tobacco smoke (ETS).

Methods: We meta-analysed data from up to 15,014 adults across 5 cohorts with DNA methylation measured in blood using Illumina's EPIC array for current smoking (2560 exposed), quit < 1 year (500 exposed), in utero (286 exposed), and ETS exposure (676 exposed). We also evaluated the interaction of current smoking with sex or diet (fibre, folate, and vitamin C).

Findings: Using false discovery rate (FDR < 0.05), 65,857 CpGs were differentially methylated in relation to current smoking, 4025 with recent quitting, 594 with in utero exposure, and 6 with ETS. Most current smoking CpGs attenuated within a year of quitting. CpGs related to in utero exposure in adults were enriched for those previously observed in newborns. Differential methylation by current smoking at 4-71 CpGs may be modified by sex or dietary intake. Nearly half (35-50%) of differentially methylated CpGs on the 450 K array were associated with blood gene expression. Current smoking and in utero smoking CpGs implicated 3049 and 1067 druggable targets, including chemotherapy drugs.

Interpretation: Many smoking-related methylation sites were identified with Illumina's EPIC array. Most signals revert to levels observed in never smokers within a year of cessation. Many in utero smoking CpGs persist into adulthood. Smoking-related druggable targets may provide insights into cancer treatment response and …

Posttraumatic stress disorder (PTSD) is associated with lower cortical thickness (CT) in prefrontal, cingulate, and insular cortices in diverse trauma-affected samples. However, some studies have failed to detect differences between PTSD patients and healthy controls or reported that PTSD is associated with greater CT. Using data-driven dimensionality reduction, we sought to conduct a well-powered study to identify vulnerable networks without regard to neuroanatomic boundaries. Moreover, this approach enabled us to avoid the excessive burden of multiple comparison correction that plagues vertex-wise methods. We derived structural covariance networks (SCNs) by applying non-negative matrix factorization (NMF) to CT data from 961 PTSD …

Rabies-virus-based monosynaptic tracing is a widely used technique for mapping neural circuitry, but its cytotoxicity has confined it primarily to anatomical applications. Here we present a second-generation system for labeling direct inputs to targeted neuronal populations with minimal toxicity, using double-deletion-mutant rabies viruses. Viral spread requires expression of both deleted viral genes in trans in postsynaptic source cells. Suppressing this expression with doxycycline following an initial period of viral replication reduces toxicity to postsynaptic cells. Longitudinal two-photon imaging in vivo indicated that over 90% of both presynaptic and source cells survived for the full 12-week course of imaging. Ex vivo …
