BACKGROUND: Pulmonary fibrosis is a challenging clinical problem with lung pathology featuring immune cell infiltrates, fibroblast expansion, and matrix deposition. Molecular analysis of diseased lungs and preclinical models have uncovered C-C chemokine receptor type 2 (CCR2)+ monocyte egress from the bone marrow into the lung, where they acquire profibrotic activities. Current drug treatment is focused on fibroblast activity. Alternatively, therapeutic targeting and monitoring CCR2+ cells may be an effective patient management strategy.
METHODS: Inhibition of CCR2+ cells and, as a benchmark, the clinical antifibrotic agent, nintedanib, were used in mouse lung fibrosis models. Lungs were evaluated directly for CCR2+ cell …

What Is The Evidence? Updates In The Use Of Antenatal Corticosteroids For Patients At Risk Of Preterm Birth, Moti Gulersen, Cynthia Gyamfi-Bannerman
Department of Obstetrics and Gynecology Faculty Papers
Antenatal corticosteroids have long been considered one of the most important antenatal therapies available for pregnant patients at risk of preterm birth based on the associated reduction of neonatal morbidity and mortality following their administration. However, despite decades of research since their incorporation into routine clinical practice, a number of key questions related to antenatal corticosteroid use remain. These include evaluating the impact of antenatal corticosteroids at gestational ages outside of the previously recommended window of 24 0/7–33 6/7 weeks of gestation, determining factors associated with optimal steroid timing in order to reduce unnecessary exposure, alterations in its dosing regimen, …

BACKGROUND: Cardiovascular disease (CVD) is a significant global health concern, particularly among Asian, Native Hawaiian, and Pacific Islander (ANHPI) communities that face unique health challenges. Liver cancer disproportionately affects ANHPI populations and has intricate associations with CVD risks due to shared pathophysiological mechanisms and metabolic disturbances. However, the specific CVD risk profile of ANHPI liver cancer patients remains poorly understood.
METHODS: Using Surveillance, Epidemiology, and End Results (SEER)-Medicare data, we identified and matched 1150 ANHPI and 2070 Non-Hispanic White (NHW) liver cancer patients diagnosed between 2000 and 2017. We used the Fine-Gray sub-distribution hazard model to estimate hazard ratios (HRs) …

BACKGROUND: People with psychosis and mood disorders experience disruptions in working memory; however, the underlying mechanism remains unknown. We focused on 2 potential mechanisms: poor attentional engagement should be associated with elevated levels of prestimulus alpha-band activity within the electroencephalogram (EEG), whereas impaired working memory encoding should be associated with reduced poststimulus alpha suppression.
METHODS: We collected EEG data from 68 people with schizophrenia, 43 people with bipolar disorder with a history of psychosis, 53 people with major depressive disorder, and 90 healthy comparison subjects while they completed a spatial working memory task. We quantified attention lapsing, memory precision, and …

Radiation Oncology Opinions And Practice On Cardiotoxicity In Lung Cancer: A Cross-Sectional Study By The International Cardio-Oncology Society, G M Walls, J D Mitchell, A R Lyon, M Harbinson, G G Hanna
2020-Current year OA Pubs
AIMS: Symptomatic radiation cardiotoxicity affects up to 30% patients with lung cancer and several heart substructure doses are associated with reduced overall survival. A greater focus on minimising cardiotoxicity is now possible due to advancements in radiotherapy technology and the new discipline of cardio-oncology, but uptake of emerging data has not been ascertained. A global cross-sectional analysis of Radiation Oncologists who treat lung cancer was therefore conducted by the International Cardio-Oncology Society in order to establish the impact of recently published literature and guidelines on practice.
MATERIALS AND METHODS: A bespoke questionnaire was designed following an extensive review of the …

Three Techniques For 360-Degree Gonioscopy-Assisted Transluminal Trabeculotomy With Itrack Advance, Sean Smith, Jessie Wang, Shivani Kamat, Arsham Sheybani, Ian Patterson, Mary Qiu
2020-Current year OA Pubs
PURPOSE: 360-degree gonioscopy-assisted transluminal trabeculotomy (GATT) is a safe and effective angle-based intervention to lower IOP. Use of the iTrack Advance allows the surgeon to efficiently advance the microcatheter in one continuous motion with a slider, an improvement upon previous techniques in which microcatheters or sutures which had to be manually threaded through Schlemm's canal with microforceps. This report demonstrates three variations in surgical technique for successful 360-degree GATT using the iTrack Advance.
OBSERVATIONS: The first technique requires retrieval of the tip of the microcatheter and requires an assistant to hold the gonioprism. The second method also requires retrieval of …

BACKGROUND: Individuals with Down syndrome (DS) are at high risk of early-onset Alzheimer's disease (AD); yet, some 20 percent do not develop any signs of dementia until after 65 years or in their lifetime. Mosaicism could contribute to this phenotypic variation, where some disomic cells could lead to lower levels of gene products from chromosome 21.
METHODS: We examined longitudinal neuropsychological and biomarker data from two large studies of DS: the Alzheimer Biomarker Consortium-Down syndrome study (ABC-DS) (n = 357); and a legacy study (n = 468). We assessed mosaicism using karyotyping or GWAS data. Participants had data on plasma …

BACKGROUND: Lung cancer and tobacco use pose significant global health challenges, necessitating a comprehensive translational roadmap for improved prevention strategies such as cancer screening and tobacco treatment, which are currently under-utilised. Polygenic risk scores (PRSs) may further motivate health behaviour change in primary care for lung cancer in diverse populations. In this work, we introduce the GREAT care paradigm, which integrates PRSs within comprehensive patient risk profiles to motivate positive health behaviour changes.
METHODS: We developed PRSs using large-scale multi-ancestry genome-wide association studies and standardised PRS distributions across all ancestries. We validated our PRSs in 561,776 individuals of diverse ancestry …

Puberty and associated changes in pubertal hormones influence structural brain development. Hormones such as dehydroepiandrosterone (DHEA) and progesterone remain understudied, and it remains unclear how these aspects of puberty contribute uniquely to structural brain development. We used the Human Connectome Project in Development cross-sectional sample of 1304 youth (aged 5-21 years) to investigate unique contributions of sex, age, pubertal stage, DHEA, testosterone, estradiol, and progesterone to cortical thickness, surface area, and subcortical volume development within functionally-relevant networks. Sex and age explain the most unique variance in all three aspects of structural development. Pubertal stage and pubertal hormones uniquely contribute more …

In higher eukaryotes, the nucleolus harbors at least three sub-phases that facilitate multiple functionalities including ribosome biogenesis. The three prominent coexisting sub-phases are the fibrillar center (FC), the dense fibrillar component (DFC), and the granular component (GC). Here, we review recent efforts in profiling sub-phase compositions that shed light on the types of physicochemical properties that emerge from compositional biases and territorial organization of specific types of macromolecules. We highlight roles played by molecular grammars which refers to protein sequence features including the substrate binding domains, the sequence features of intrinsically disordered regions, and the multivalence of these distinct types …
