Maturational Patterns Of Left Ventricular Rotational Mechanics In Pre-Term Infants Through 1 Year Of Age, Gloria C Lehmann, Philip T Levy, Meghna D Patel, Timothy Sekarski, Hongjie Gu, Swati Choudhry, Aaron Hamvas, Gautam K Singh

Open Access Publications

BACKGROUND: Pre-mature birth impacts left ventricular development, predisposing this population to long-term cardiovascular risk. The aims of this study were to investigate maturational changes in rotational properties from the neonatal period through 1 year of age and to discern the impact of cardiopulmonary complications of pre-maturity on these measures.

METHODS: Pre-term infants (<29 weeks at birth, n = 117) were prospectively enrolled and followed to 1-year corrected age. Left ventricular basal and apical rotation, twist, and torsion were measured by two-dimensional speckle-tracking echocardiography and analysed at 32 and 36 weeks post-menstrual age and 1-year corrected age. A mixed random effects model with repeated measures analysis was used to compare rotational mechanics over time. Torsion was compared in infants with and without complications of cardiopulmonary diseases of pre-maturity, specifically bronchopulmonary dysplasia, pulmonary hypertension, and patent ductus arteriosus.

RESULTS: Torsion decreased from 32 weeks post-menstrual age to 1-year corrected age in all pre-term infants (p < 0.001). The decline from 32 to 36 weeks post-menstrual age was more pronounced in infants with cardiopulmonary complications, but was similar to healthy pre-term infants from 36 weeks post-menstrual age to 1-year corrected age. The decline was due to directional and magnitude changes in apical rotation over time (p < 0.05).

CONCLUSION: This study tracks maturational patterns of rotational mechanics in pre-term infants and reveals torsion declines from the neonatal period through 1 year. Cardiopulmonary diseases of pre-maturity may negatively impact …

Cathepsin S And Protease-Activated Receptor-2 Drive Alloimmunity And Immune Regulation In Kidney Allograft Rejection, Yutian Lei, Benjamin Ehle, Santhosh V Kumar, Susanne Müller, Solange Moll, Andrew F Malone, Benjamin D Humphreys, Joachim Andrassy, Hans-Joachim Anders

Open Access Publications

Alloantigen presentation is an essential process in acute allorejection. In this context, we speculated on a pathogenic role of cathepsin S (Cat-S), a cysteine protease known to promote antigenic peptide loading into MHC class II and to activate protease-activated receptor (PAR)-2 on intrarenal microvascular endothelial and tubular epithelial cells. Single-cell RNA sequencing and immunostaining of human kidney allografts confirmed Cat-S expression in intrarenal mononuclear phagocytes.

Come Together: Protein Assemblies, Aggregates And The Sarcostat At The Heart Of Cardiac Myocyte Homeostasis, Moydul Islam, Abhinav Diwan, Kartik Mani

Open Access Publications

Homeostasis in vertebrate systems is contingent on normal cardiac function. This, in turn, depends on intricate protein-based cellular machinery, both for contractile function, as well as, durability of cardiac myocytes. The cardiac small heat shock protein (csHsp) chaperone system, highlighted by αB-crystallin (CRYAB), a small heat shock protein (sHsp) that forms ∼3-5% of total cardiac mass, plays critical roles in maintaining proteostatic function via formation of self-assembled multimeric chaperones. In this work, we review these ancient proteins, from the evolutionarily preserved role of homologs in protists, fungi and invertebrate systems, as well as, the role of sHsps and chaperones in …

Prostate Cancer Theranostics - An Overview, Diane Abou, Nadia Benabdallah, Wen Jiang, Lu Peng, Hanwen Zhang, Alexandria Villmer, Mark S Longtine, Daniel L J Thorek

Open Access Publications

Metastatic prostate cancer is incurable, and novel methods to detect the disease earlier and to direct definitive treatment are needed. Molecularly specific tools to localize diagnostic and cytotoxic radionuclide payloads to cancer cells and the surrounding microenvironment are recognized as a critical component of new approaches to combat this disease. The implementation of theranostic approaches to characterize and personalize patient management is beginning to be realized for prostate cancer patients. This review article summarized clinically translated approaches to detect, characterize, and treat disease in this rapidly expanding field.

Using A Developmental Perspective To Examine The Moderating Effects Of Marriage On Heavy Episodic Drinking In A Young Adult Sample Enriched For Risk, Seung Bin Cho, Rebecca L Smith, Kathleen Bucholz, Grace Chan, Howard J Edenberg, Victor Hesselbrock, John Kramer, Vivia V Mccutcheon, John Nurnberger, Marc Schuckit, Yong Zang, Danielle M Dick, Jessica E Salvatore

Open Access Publications

Many studies demonstrate that marriage protects against risky alcohol use and moderates genetic influences on alcohol outcomes; however, previous work has not considered these effects from a developmental perspective or in high-risk individuals. These represent important gaps, as it cannot be assumed that marriage has uniform effects across development or in high-risk samples. We took a longitudinal developmental approach to examine whether marital status was associated with heavy episodic drinking (HED), and whether marital status moderated polygenic influences on HED. Our sample included 937 individuals (53.25% female) from the Collaborative Study on the Genetics of Alcoholism who reported their HED …

Open Access Publications

OBJECTIVE: Despite recommendations to discontinue prophylactic antibiotics after incision closure or <24 hours after surgery, prophylactic antibiotics are continued after discharge by some clinicians. The objective of this study was to determine the prevalence and factors associated with postdischarge prophylactic antibiotic use after spinal fusion.

DESIGN: Multicenter retrospective cohort study.

PATIENTS: This study included patients aged ≥18 years undergoing spinal fusion or refusion between July 2011 and June 2015 at 3 sites. Patients with an infection during the surgical admission were excluded.

METHODS: Prophylactic antibiotics were identified at discharge. Factors associated with postdischarge prophylactic antibiotic use were identified using hierarchical generalized linear models.

RESULTS: In total, 8,652 spinal fusion admissions were included. Antibiotics were prescribed at discharge in 289 admissions (3.3%). The most commonly prescribed antibiotics were trimethoprim/sulfamethoxazole (22.1%), cephalexin (18.8%), and ciprofloxacin (17.1%). …

Incipient Alcohol Use In Childhood: Early Alcohol Sipping And Its Relations With Psychopathology And Personality, Ashley L Watts, Phillip K Wood, Kristina M Jackson, Krista M Lisdahl, Mary M Heitzeg, Raul Gonzalez, Susan F Tapert, Deanna M Barch, Kenneth J Sher

Open Access Publications

Prior research has shown that sipping of alcohol begins to emerge during childhood and is potentially etiologically significant for later substance use problems. Using a large, community sample of 9- and 10-year-olds (N = 11,872; 53% female), we examined individual differences in precocious alcohol use in the form of alcohol sipping. We focused explicitly on features that are robust and well-demonstrated correlates of, and antecedents to, alcohol excess and related problems later in the lifespan, including youth- and parent-reported externalizing traits (i.e., impulsivity, behavioral inhibition and activation) and psychopathology. Seventeen percent of the sample reported sipping alcohol outside of a …

Promoting Undetectable Equals Untransmittable In Sub-Saharan Africa: Implication For Clinical Practice And Art Adherence, Nicholas Ekow Thomford, Doreen Mhandire, Collet Dandara, George B Kyei

Open Access Publications

In the last decade, reliable scientific evidence has emerged to support the concept that undetectable viral loads prevent human immunodeficiency virus (HIV). Undetectable equals untransmissible (U = U) is a simple message that everyone can understand. The success of this concept depends on strict adherence to antiretroviral therapy (ART) and the attainment of suppressed viral loads (VLs). To achieve U = U in sub-Saharan Africa (SSA), poor adherence to ART, persistent low-level viremia, and the emergence of drug-resistant mutants are challenges that cannot be overlooked. Short of a cure for HIV, U = U can substantially reduce the burden and …
