Comprehensive Normalization And Binary Classification Methods For Enhanced Sensitivity And Reproducibility In Luminex Assay Quantitation, B A Burns, C A Shaw, M Chandra, C S Forconi, A M Moormann, V Konduri, V N Tubman, W K Decker

Faculty, Staff and Students Publications

The Luminex assay is a powerful tool for large-scale quantitation of antibody levels and cytokines, but its utility can be limited by issues of specificity, sensitivity, and reproducibility. The corrections for background fluorescence and machine drift are essential steps in the normalization process. However, traditional methods often oversimplify these steps, failing to account for the complexity of the data, leading to the introduction of error and decreasing the sensitivity and reproducibility of the analysis. Furthermore, conventional methods to determine cut-points in binary measures do not consider the true distribution of the data, leading to arbitrary cut-points that compromise the integrity …

Vaginal fibrosis induced by cancer therapy continues to take a physical and psychoemotional burden. To advance the efforts to generate a reproducible and cost-effective animal model, we tested the effect of repeated bleomycin instillations with mucosal layer disruption on induction of vaginal fibrosis. Tissue samples collected at various time points were analyzed for fibrosis-related gene expression changes and collagen content. Low (1.5 U/kg) and high-dose (2.5 U/kg) bleomycin instillations alone did not induce fibrosis, but when high-dose bleomycin was combined with epithelial disruption, increased profibrotic gene expression and trichrome staining were observed. To evaluate spatial and temporal changes in the …

Background: Gestational diabetes mellitus affects up to 10% of pregnancies and is classified into subtypes gestational diabetes subtype A1 (GDMA1) (managed by lifestyle modifications) and gestational diabetes subtype A2 (GDMA2) (requiring medication). However, whether these subtypes are distinct clinical entities or more reflective of an extended spectrum of normal pregnancy endocrine physiology remains unclear.

Objective: Integrated bulk RNA-sequencing (RNA-seq), single-cell RNA-sequencing (scRNA-seq), and spatial transcriptomics harbors the potential to reveal disease gene signatures in subsets of cells and tissue microenvironments. We aimed to combine these high-resolution technologies with rigorous classification of diabetes subtypes in pregnancy. We hypothesized that differences between …

We observed shifting trends in tuberculosis (TB) epidemiology in the EU/EEA between 2019 and 2023. In 2023, TB notifications among people of foreign origin increased by 24.6% after decreasing between 2019 and 2020. The majority originated from African and East Mediterranean regions, with a 316.4% upsurge in TB among Ukrainians in 2022-23. Rifampicin-resistant/multidrug-resistant TB increased by ≥ 60% in 2019-23, mainly among Ukrainians. Rapid response to shifting epidemiological patterns is crucial for efficient TB prevention and control within the EU/EEA.

Early Life Epigenetics And Childhood Outcomes: A Scoping Review, Srirupa Hari Gopal, Theresa Alenghat, Mohan Pammi

Faculty, Staff and Students Publications

Epigenetics is the study of changes in gene expression, without a change in the DNA sequence that are potentially heritable. Epigenetic mechanisms such as DNA methylation, histone modifications, and small non-coding RNA (sncRNA) changes have been studied in various childhood disorders. Causal links to maternal health and toxin exposures can introduce epigenetic modifications to the fetal DNA, which can be detected in the cord blood. Cord blood epigenetic modifications provide evidence of in-utero stressors and immediate postnatal changes, which can impact both short and long-term outcomes in children. The mechanisms of these epigenetic changes can be leveraged for prevention, early …

Cerebrotendinous Xanthomatosis Occurs At High Frequency In Ashkenazi Jews, Jennifer Hanson, Penelope E Bonnen

Faculty, Staff and Students Publications

Cerebrotendinous Xanthomatosis (CTX) is a treatable, inborn error of bile acids metabolism caused by pathogenic variants in CYP27A1. CTX is a multi-organ system disorder that progresses over decades. Clinical features include cerebellar dysfunction, pyramidal tract dysfunction, cognitive deficits and decline, peripheral neuropathy, chronic diarrhea, bilateral cataracts, and tendon xanthomas. Treatment is effective when started early, but diagnostic delays often result in individuals not being diagnosed until after the window of highest treatment efficacy. CTX is documented to occur in most global populations, however, no CTX-causing genetic variants have been reported in Ashkenazi Jews. We conducted a systematic review of every …

Pseudotumor Tensor Fascia Lata Syndrome From Underlying Severe Lumbar Stenosis: A Case Report, Zane Shah, Won J Jeong, Wyatt I Kupperman, Yonghoon Lee

Faculty, Staff and Students Publications

A pseudotumor of the tensor fascia lata (TFL) describes a rare condition characterized by hypertrophy or pseudohypertrophy of the TFL that can mimic a soft tissue mass. Without the right clinical suspicion, it can be misdiagnosed as a benign or malignant soft tissue tumor, leading to oncologic workups. Unnecessary workups can cause patient distress, waste resources, and delay the management of the condition and its associated symptoms. Here, we describe a 65-year-old male who developed a pseudotumor of the TFL in the setting of severe lumbar spinal stenosis. The etiology for this patient was suspected to be a combination of …

Glioblastoma is the most common primary malignant brain tumor in adults, with a median survival of just over 1 year. The failure of available treatments to achieve remission in patients with glioblastoma (GBM) has been attributed to the presence of cancer stem cells (CSCs), which are thought to play a central role in tumor development and progression and serve as a treatment-resistant cell repository capable of driving tumor recurrence. In fact, the property of "stemness" itself may be responsible for treatment resistance. In this study, we identify a novel long noncoding RNA (lncRNA), cancer stem cell-associated distal enhancer of SOX2 …

An Unusual Presentation Of Subcutaneous Inguinal Hematoma Mimicking Ovarian Torsion: A Case Report, Chrystal Stallworth, Timothy Kremer, Victoria Panzanaro Feb 2025

An Unusual Presentation Of Subcutaneous Inguinal Hematoma Mimicking Ovarian Torsion: A Case Report, Chrystal Stallworth, Timothy Kremer, Victoria Panzanaro

HCA Healthcare Journal of Medicine

Background

Ovarian or adnexal torsions occur when an ovary rotates around one of the supporting ligaments, often the infundibulopelvic (IP) ligament. This rotation can cause the blood flow to the ovary to be hindered, and this decrease in perfusion can often present as adnexal pain, nausea, and vomiting. A significant risk factor for developing an ovarian torsion is the presence of an ovarian mass, such as a cyst. The diagnosis of ovarian torsion is a medical emergency, but symptoms typically resolve with prompt surgical intervention. Hematomas occurring within or around the inguinal region have been reported to occur primarily after …

Background

Early palliative care practice implementation in the intensive care unit (ICU) improves advance care planning, promotes patient and family satisfaction, and decreases health care costs. The consensus for protocolized palliative care delivery is unknown. We assessed the impact of a qualitive improvement educational intervention that promotes the identification of critically ill patients who will benefit from early expert palliative care interventions.

Methods

In this observational study, we examined the impact of an educational intervention that promoted (1) early detection of palliative care triggers (PCT) during ICU multidisciplinary rounds (MDRs), (2) admission and 48-hour pain assessment, and (3) family meetings …

Idiopathic pulmonary fibrosis (IPF) is a progressive disease characterized by gradual destruction and replacement of pulmonary parenchyma with fibrous tissue, which occurs in conjunction with chronic inflammation. It is often considered a prototypical interstitial lung disease and is both the most prevalent and perhaps the most dangerous in that family. Although the disease is uncommon in the general population, its prevalence increases with age and is typically diagnosed around the age of 65. This does not preclude the development of IPF in younger individuals, and the mean survival is 2 to 5 years post-diagnosis regardless of age. Contemporary studies have …
