First In The Field: Pioneering In Structural Heart Interventional Echocardiography, Alex Pui-Wai Lee

Journal of the Hong Kong College of Cardiology

Structural heart disease (SHD) has emerged as one of the most dynamic frontiers in contemporary cardiology. Interventional echocardiography, once a niche discipline, is now central to the planning, execution, and follow-up of complex structural interventions. This comprehensive review traces the evolution of the field, anchored in both scientific literature and firsthand experience. We explore the journey from 2D to 3D imaging, the impact of mentorship and research at the Mayo Clinic, the rise of advanced interventional devices, the integration of artificial intelligence and robotics, and the importance of resilience and teamwork. Our aim is to inspire, inform, and chart a …

An Unusual Cause Of Acute Constrictive Pericarditis, Yue Hin Tang, Raymond Chi Yan Fung

Journal of the Hong Kong College of Cardiology

Constrictive pericarditis, a condition where the pericardium thickens and constricts, has long been considered as a chronic sequela of prior insults to the pericardium such as heart surgery, repeated pericarditis, tuberculosis infection, radiation exposure, etc. Susceptible populations are thus expected to be middle-aged.

We present a case in which a young gentleman was diagnosed with acute constrictive pericarditis due to Adult-onset Still’s disease with macrophage activation syndrome. This case illustrated that constrictive pericarditis could happen in acute settings and thus the importance of cardiologists to maintain open-minded in search of a diagnosis

Corruption Perception, Institutional Quality And Stock Prices: Evidence From The Egyptian Capital Market, Rasha Elbolok, Gina Eltabei, Dina Hassouna

Business Administration

This study examines the impact of institutional quality and corruption perception on stock prices in the Egyptian capital market, with a focus on the post-revolution period from to . Using the Generalized Method of Moments (GMM) methodology, this study provides empirical evidence on the significant role of macro-political factors and firm-specific variables in shaping stock market dynamics. The findings reveal that institutional quality, characterized by governance efficiency, regulatory frameworks, and the rule of law, positively correlates with stock prices. Similarly, enhanced corruption perception control significantly boosts investor confidence, leading to increased market valuations. Firm-level factors such as Tobin’s Q and …

Determination Of Titanium Speciation In Consumer Plastics By Raman Microspectroscopy, Johanna Brazard, Takuji B.M. Adachi, Andrew Turner, Montserrat Filella

School of Geography, Earth and Environmental Sciences

The main component of objects made of plastic is an organic polymer matrix, but plastics also contain a wide range of other chemicals, such as additives, processing aids and unintentionally added substances. At present, the scientific and regulatory communities face challenges due to the lack of access to basic information on their quantity and identity, which is crucial in relation to potential toxicity, management, recycling, environmental fate and resource uses. Moreover, an additional problem is that some additives, such as titanium oxide (TiO₂), can be present in different crystallographic forms, which makes it necessary to characterise not only …

Salinity Controls On Steel Biocorrosion Relevant To The Disposal Of High-Level Radioactive Waste, M. N. Rose, C. Boothman, S. Shaw, K. Morris, D. L. Engelberg, M. T. Bailey, J. R. Lloyd

School of Geography, Earth and Environmental Sciences

In a geological disposal facility (GDF) for spent fuel and high-level radioactive waste, the canister serves as one of the main engineered barriers. The resistance of the canister to degradation processes such as microbially influenced corrosion (MIC) needs be characterised to support GDF environmental safety cases. Here the impacts of salinity on sulfate-reducing bacterial (SRB) activity and associated MIC were explored in 84-day batch incubations at 30 °C. A 5 % standard bentonite slurry (MX80) in a low-salinity (0.1 g l⁻¹ NaCl) artificial groundwater containing lactate added as an electron donor provided suitable conditions for the proliferation of SRB. …

Export Diversification And Economic Growth In Sub-Saharan Africa: Could There Be A Mixed Relationship?, Jocelyne Urielle Bedime, Julien Brice Minkande, Honoré Bidiasse

Journal of African Trade

Based on the differences in export diversification between sub-regions, this research aims to determine the type of relationship that may exist between export diversification and economic growth in Sub-Saharan Africa. Using data from 36 countries grouped according to their level of diversification, a panel ARDL model is estimated. The results show that for highly diversified sub-regions, the relationship between export diversification and economic growth is inverted U-shaped, while for concentrated sub-regions, the relationship is U-shaped. Highly diversified countries are advised to integrate further into the African continental free-trade zone, which, by lifting barriers and improving the regulatory framework, offers greater …

The Potential Impact Of The African Continental Free Trade Area On Ethiopia's Total Exports And Real Gdp Growth, Simachew Zelalem Mengistu

Journal of African Trade

This study examines the potential impact of the African Continental Free Trade Area (AfCFTA) on Ethiopia's export growth and real GDP using the General Equilibrium Poisson Pseudo Maximum Likelihood (GEPPML) estimation model. Despite Africa's longstanding efforts toward economic integration, intra-African trade remains low, with Ethiopia's export structure heavily reliant on primary agricultural commodities and limited diversification into high-value or technology-intensive sectors. The paper employs a three-stage GEPPML approach to simulate the effects of AfCFTA, accounting for trade elasticities, multilateral resistance terms, and endogenous income adjustments.

The findings indicate that AfCFTA could enhance Ethiopia's export growth by 1.137% and real GDP …

Dividing Trademark Use, Jeremy N. Sheff

Faculty Publications

The trademark law of the United States places special emphasis on whether and how a trademark is used in commerce. But over the long history of the Lanham Act—including some less-than-careful drafting by Congress and some aggressive acts of interpretation by the federal courts—the concept of “use” has become complicated and in many ways confused. Two recent Supreme Court cases—Jack Daniel’s Properties, Inc. v. VIP Products LLC and Abitron Austria GmbH v. Hetronic International, Inc.—reflect and in some ways exacerbate that confusion. But the opinions in these cases also expose an interesting property of “use” in trademark law …

The Whiteness Of Wealth & Black Student Loan Debt, Renee Nicole Allen

Faculty Publications

On June 30, 2023, to the dismay of many anxious borrowers, the Supreme Court held that the Secretary of Education did not have the authority to cancel roughly $430 billion in federal student loan balances, thus blocking President Biden’s plan for student loan forgiveness. Despite authority delegated to the Secretary to waive or modify provisions of the Education Act to ensure low-to-middle income borrowers were not placed in a worse financial position because of the COVID-19 national emergency, the Court rejected the forgiveness plan and borrowers resumed payments in October 2023. Anti-Black racism in federal law and policy have contributed …

The Effect Of Deferring Feedback On Rule-Based And Information-Integration Category Learning, Charlotte E.R. Edmunds, Kathryn Carpenter, Andy J. Wills, Fraser Milton

School of Psychology

Previous work has shown that deferring feedback significantly impairs two-dimensional information-integration category learning, often thought to recruit an implicit learning system, but leaves intact unidimensional rule-based learning, commonly assumed to engage an explicit system. These results were taken to support the influential COmpetition between Verbal and Implicit Systems (COVIS) dual-process theory. This conclusion has subsequently been challenged by the finding that this dissociation disappears when the number of relevant dimensions is matched between tasks. However, as well as replacing a unidimensional rule-based task with a two-dimensional conjunction task, a different set of stimuli were used making it unclear which of …

An Immanent Postfoundational Methodology For Researching The Violent Trans-Sections Of Ableism, Classism And Sexism, Elizabeth Done, Cara Baer

School of Law, Humanities and Social Sciences

This paper charts the unfolding of a small-scale qualitative study, presented at institutional ethical approval stage as drawing on posthumanist theorising and seeking to (re)configure the concept of intersectionality, and focusing on the lived experience of postgraduate students of lower socio-economic status with disabilities. The self-selected sample comprised six women, three of whom volunteered accounts of sexual violence that complicated their experiences of dis-ability and class, and highlighted the complexity of their lived experience of intersectionality. We describe a research process in which interviewing became intra-viewing, lived experience came to be understood through Deleuzian and Deleuzo-guattarian concepts and intersectionality became …

Investigation Of A Busemann Intake At Negative Angle Of Attack, Mark E. Noftz, Andrew N. Bustard, Nicholas J. Bisek, Thomas J. Juliano, Joseph S. Jewell

Publications

A high-speed, shape-transitioned, inward-turning intake was tested in Purdue’s Boeing/AFOSR Mach 6 Quiet Tunnel. The inlet model, called the Indiana Inlet (INlet), had a total contraction ratio of 4.68:1 and a design point of Mach 6 at 0° angle of attack. The model was outfitted with a suite of high-frequency pressure transducers, and the external flowfield was imaged with high-speed schlieren photography. The INlet was tested under low freestream disturbance levels for a variety of freestream unit Reynolds numbers and at-4° angle of attack. An unsteady shockwave near the leading edge of the inlet forebody, indicative of boundary layer separation, …

Scar Tissue Adhesions, Neuromuscular Guarding, And Functional Recovery: A Case Report Of Physical Therapy Post-Cholecystectomy, Raeisa Griñe, Adam Walsh

Western Journal of Orthopaedics

Scar tissue from abdominal surgeries, such as cholecystectomy, can lead to long-term issues such as restricted movement, painful spasms, and impaired function. Laparoscopic adhesiolysis is a common surgical treatment for pathological scar tissue impairments. Conservative care, such as physical therapy, is a commonly used approach for managing pathological scar tissue. In this case, manual therapy techniques and targeted exercises successfully reduced the intensity and frequency of abdominal spasms, improved core strength and endurance, and enhanced overall functional mobility. These improvements were reflected in enhanced scores on the Lower Extremity Functional Scale and the Vancouver Scar Scale in a 59-year-old woman …

Treatment Of Congenital Cruciate Ligament Absence In A Teenager Knee-Ding Stability, Gaurav Singh, Anna Bergquist, Rebecca Peebles, Justin Bartley

Western Journal of Orthopaedics

The congenital absence of the anterior cruciate ligament (ACL) and posterior cruciate ligament (PCL) is an extremely rare condition, with an estimated prevalence of 0.017 per 1,000 live births for ACL agenesis. The authors present the case of a 15-year-old adolescent girl with autosomal dominant multiple synostosis, who developed progressive bilateral knee pain and functional limitations. Bilateral knee x-rays revealed trochlear dysplasia and an absent tibial eminence, suggesting a congenital ligamentous abnormality. Magnetic resonance imaging confirmed the bilateral absence of both the ACL and PCL. Surgical reconstruction of both ligaments was performed, with the first procedure taking place in October …

Western Journal of Orthopaedics

This report documents a unique, successful strategy to manage a failed anterior cruciate ligament reconstruction (ACLR) in the setting of coronal and sagittal plane malalignment. The patient is a 38-year-old man with a history of a failed ACLR who presented with recurrent knee instability. Imaging revealed a posterior tibial slope (PTS) of 17° complicated by a varus malalignment of 10°. A single-stage anterior and lateral closing wedge tibial osteotomy (biplanar) with simultaneous revision anterior cruciate ligament reconstruction was performed. Final radiographic evaluation revealed that the tibial osteotomy healed with correction of coronal alignment to a physiologic 3° varus and a …

Rare Case Of Fungal Osteomyelitis Affecting An Intramedullary Lag Screw, Matthew C. Watterson, Robert T. Rella, Timothy K. Summers, David Michaeli, Jess Mullens

Western Journal of Orthopaedics

Osteomyelitis is an infection of the bone that is most commonly of bacterial origin. Cases of fungal osteomyelitis are rare, and treatment often requires a prolonged course of antimicrobials. The authors report a case of a 72-year old man with fungal osteomyelitis affecting an intracortical lag screw, which was discovered during fixation of the left femoral shaft following an injury that occurred 68 years after placement of the affected lag screw. Chronic osteomyelitis can be indolent and subclinical, with the patient experiencing no signs or symptoms of the disease despite having bone infection for decades. This condition may become clinically …

Recurrent Baker’S Cyst In A Pediatric Athlete: A Case Report, Gaurav Singh, Rebecca Peebles, Justin Bartley

Western Journal of Orthopaedics

Also known as popliteal cysts, Baker’s cysts are fluid-filled lesions found in the popliteal fossa, typically originating from the gastrocnemius-semimembranosus bursa. While these cysts are relatively common in adults, with a prevalence ranging from 5.0% to 41.0%, they are extremely rare in children, showing an incidence of just 2.4%. In most cases, Baker’s cysts result from intra-articular knee pathologies that lead to an increased production and sequestration of synovial fluid. The authors present the case of an athletic 16-year-old adolescent boy with a recurrent left-knee Baker’s cyst with magnetic resonance imaging showing no intra-articular pathology. Despite conservative treatment, including non-steroidal …

Fluoroscopy-Guided Versus 3d Navigated Percutaneous Sacroiliac Screw Fixation: A Comparison Of Radiation Exposure And Surgical Duration, Tyler J. Chavez, Jeremiah M. Langsfeld, Solomon Oloyede, Gordon H. Lee, Urvij Modhia

Western Journal of Orthopaedics

Background: Pelvic ring injuries are complex surgical challenges requiring significant radiation exposure for safe placement of sacroiliac (SI) screw fixation. Traditionally, SI fixation has been performed with conventional C-arm fluoroscopy to guide screw placement. 3D navigated imaging is a technique that uses fluoroscopic scans and a navigation tracker to guide screws in space. The purpose of this study is to characterize a single institution’s experience with navigated SI fixation and the resulting radiation exposure to patient and staff. Methods: Records of 60 patients who underwent SI fixation using either conventional fluoroscopy (43) or 3D navigation (17) were reviewed. Exposure data …

Artificial Intelligence And Seeing The Invisible In Arts - From The Wane Of Axiality And Symmetry To The Wax Of Invisibility And Emptiness, M. Samir Abou El-Seoud

Computer Science

Function has been always an important driver in architectural design. It is the request to generate form directly from purpose and utility. In 1896, Louis Sullivan projected that ‘form follows function’ and that the beauty of a building derives directly from its function and not from references of the built heritage. The assumption was that beauty would naturally derive from design once functional requirements are met. Thus, fitness for purpose equals beauty. In 1908, Adolf Loos even went so far as to ask for the total abandonment of decoration. In 1947, Mies van der Rohe made his paradigm shift, function …

Factors Affecting Metabolism And Metabolic Control In Phenylketonuria, Alex Amorim Pinto

School of Health Professions Theses

Phenylketonuria (PKU) is an inherited metabolic disorder treated by a phenylalanine restricted diet in order to avoid neurocognitive impairment. Blood phenylalanine is the main outcome marker which is modulated by many dietary factors. Traditionally, L-amino acid-based protein substitutes are the main nitrogen source but more recently glycomacropeptide-based protein substitutes (GMP) have been introduced and are associated with several health benefits. The following aspects were studied in this thesis: 1) metabolic control achieved in patients with PKU compared with the European PKU guidelines; 2) life-long change in natural protein tolerance; 3) impact on metabolic control of different natural protein sources (animal …
