Background and objectives: Acute kidney injury (AKI) poses a serious clinical challenge, particularly in high-risk environments, due to its association with increased morbidity and mortality. Traditional diagnostic markers, such as serum creatinine, often detect AKI only after significant kidney damage has occurred, limiting opportunities for early intervention. Neutrophil gelatinase-associated lipocalin (NGAL) has emerged as a promising early biomarker due to its rapid upregulation following kidney ischemia. NGAL supports renal recovery by reducing toxicity and promoting tubular regeneration via heme oxygenase-1 activity. This study aimed to validate the BioPorto ProNephro AKI™ turbidimetric immunoassay for urinary NGAL on the Ortho Vitros XT7600 …

Colonisation of mosquitos by the malarial parasite is critically reliant on the invasive ookinete stage. Ookinete invasion of mosquito is coordinated by the apical complex, a specialised parasite structure containing components for secretion, attachment and penetration. While studies have investigated cytoskeletal and secretory elements, it is currently unknown if signalling modules are present or functional at the apical complex. Here we elucidate the role of a cryptic cyclic nucleotide-binding protein which we name CBP-O. PbCBP-O showed a marked localisation to the ookinete apex and disruption of the protein severely compromised ookinete invasion of mosquitos. Domain dissection analysis revealed that the …

Introduction: Obesity presents a significant health risk for the aging population. Research shows that weight loss and regular exercise can greatly improve the functional status of older adults who are obese. However, weight loss may also result in a decrease in bone mass. To properly assess changes in fracture risk due to lifestyle interventions, a direct biomechanical evaluation of bone strength and fracture risk at metabolically active sites is essential.

Methods: Computed tomography scans taken at two different time points of ten human volunteers provided the foundation for this study. A high-fidelity segmentation and modeling approach was taken to generate …

Posttraumatic stress disorder (PTSD) and obsessive-compulsive disorder (OCD) share ostensibly similar and sometimes overlapping symptoms that complicate diagnostic assessment and conceptualization. While varying models for the symptom structure of PTSD have been proposed - including the presently used 4-factor and a more fine-grained 7-factor model - little research has focused on youth and even less is known about how these symptoms relate to one another when OCD is present. The present study used confirmatory factor analysis (CFA) and network analysis to compare PTSD symptom relations among 2066 trauma-exposed youth aged 8-20 enrolled in the Texas Childhood Trauma Research Network, of …

Many 1990-1991 Gulf War Veterans (GWVs) were exposed to toxicants and environmental hazards during deployment, including oil well fire smoke, chemical/biological agents, pyridostigmine bromide (PB) pills, and pesticides. Multiple constituents of smoke are associated with increased risk for atherosclerotic cardiovascular diseases (ASCVD), and other toxic exposures have been associated with autonomic and lipid dysfunction. We used data from the Gulf War Era Cohort and Biorepository Study of veterans deployed to Gulf War in 1990-1991 (n = 942). We evaluated the association of deployment exposures (no, yes (1-6 days), (7-30 days), (31 + days), and not sure) with clinical risk factors …

Febrile infection-related epilepsy syndrome (FIRES) is a rare presentation of refractory status epilepticus following a febrile illness with resulting refractory epilepsy. Evidence supports the presence of immune dysregulation in patients with FIRES, but a monogenic basis for FIRES has not been identified in most cases. We present a case of a previously healthy 16-year-old male with FIRES who was found to have a de novo predicted damaging missense variant in CSF1R on clinical whole genome sequencing, a gene encoding a critical regulator of microglial homeostasis in which pathogenic variants cause adult onset leukoencephalopathy. Molecular modeling demonstrates that the CSF1R variant …

Faculty, Staff and Students Publications

Age-related macular degeneration (AMD) has significant genetic component, yet monozygotic twins frequently exhibit discordance in disease status, highlighting the role of non-genetic factors. To enable comparative studies of AMD pathogenesis, we generated two induced pluripotent stem cell (iPSC) lines from peripheral blood mononuclear cells (PBMCs) of a monozygotic twin pair discordant for AMD. These iPSC lines offer a unique genetically matched resource to investigate molecular differences between affected and unaffected twins, as well as their responses to genetic, epigenetic, and environmental contributors to AMD development.

Excision And Regional Flap Reconstruction With Radiation Therapy Of Granuloma Annulare Of The Digit: A Case Report, Austin Y Jiang, Linda K Green, David Netscher

Faculty, Staff and Students Publications

Granuloma annulare (GA) is a benign, often self-limited granulomatous skin condition that typically resolves spontaneously. Treatment is often not required, but topical and injectional corticosteroids are the most common interventions. Excision is effective for diagnosis and temporary treatment, but usually not considered curative. This case report describes the unconventional treatment of a recurrent biopsy-proven GA of the index finger. Due to the combination of the recalcitrant nodules interfering with function and patient preference, the nodules were excised multiple times. Ultimately requiring reconstruction with a pedicled radial forearm flap, the patient thereafter received radiation therapy to prevent recurrence, the combination of …

Acute Loss Of Tactile Input Leads To General Compensatory Changes In Eye-Hand Coordination During Object Manipulation, Kevin Ung, John F Magnotti, Brandon Kim, Jeffrey M Yau, Per F Nordmark

Faculty, Staff and Students Publications

Current models of motor control emphasize the critical role of sensory feedback, as demonstrated by movement coordination deficits following sensory impairment. When both vision and touch are available for object-oriented manual behaviors, they serve distinct roles; vision guides the execution of planned movements, while touch provides more direct feedback on hand-object interactions. The impact of losing somatosensory feedback on eye-hand coordination during dexterous object manipulation tasks has not been thoroughly studied. Conceivably, vision is recruited to compensate for the feedback lost when touch is abolished based on the dexterity demands of the behavior. To investigate this, we tested healthy participants …

Dysfunctional mechanosensing via focal adhesions (FAs) significantly contributes to thoracic aortic dissection in the β-aminopropionitrile mouse model by triggering FA kinase activation and subsequent Rho/ROCK and mTOR signaling pathways. The present findings indicate that these signaling pathways play distinct roles in ascending vs descending dissections. Specifically, in the ascending aorta, smooth muscle cell FA kinase-Rho/ROCK signaling acts as a beneficial adaptive mechanism to prevent dissections, whereas mTOR signaling is pathogenic and contributes to dissections.

Mucormycosis is a rare, life-threatening opportunistic infection primarily affecting immunocompromised patients. The available literature on Rhizomucor pusillus (R pusillus) infections of the central nervous system (CNS) in children is very limited. We present the case of an immunocompromised adolescent with intracranial mucormycosis due to R pusillus manifesting with stroke-like symptoms. This case highlights this rare condition's diagnostic complexity and management challenges. We include a review of the available literature on pediatric R pusillus CNS infections to increase awareness among health care providers.

Introduction: High-flow nasal cannula (HFNC) and continuous positive airway pressure delivered via a nasal interface (nCPAP) are increasingly used for paediatric emergency care in South Africa. In Cape Town, initiation of HFNC/nCPAP at a district hospital, in most instances, necessitates transfer to a paediatric high-care facility. We sought to describe the population of children initiated on HFNC/nCPAP and their short-term hospital outcomes post interfacility transfer.

Methods: The authors conducted a one-year retrospective observational study between August 1st 2021, to July 31st, 2022 of children initiated on HFNC or nCPAP in the emergency centre (EC) of Khayelitsha district Hospital and transferred …
