Not A Box Of Nuts And Bolts: Distribution Channels For Specialty Drugs?, Liang Xu, Vidya Mani, Hui Zhao Jul 2023

Not A Box Of Nuts And Bolts: Distribution Channels For Specialty Drugs?, Liang Xu, Vidya Mani, Hui Zhao

Research Collection Lee Kong Chian School Of Business

One of the most important trends in the pharmaceutical industry is the rapid growth of specialty drugs. Specialty drugs, mostly bio based, tend to be high risk, high priced, and more regulated than traditional drugs, resulting in unprecedented challenges in distribution. Such challenges lead to the emergence of specialty distributors (SDs), which, compared with traditional wholesalers (WSs), represent a more controlled channel and carry a smaller variety of drugs. Due to the risky nature of specialty drugs, manufacturers must consider the trade-off between access and control in determining whether to use SDs (partially or exclusively). Using a unique dataset assembled …

Free Ferrous Ions Sustain Activity Of Mammalian Stearoyl-Coa Desaturase-1, Jiemin Shen, Gang Wu, Brad S Pierce, Ah-Lim Tsai, Ming Zhou

Faculty, Staff and Student Publications

Mammalian stearoyl-CoA desaturase-1 (SCD1) introduces a double-bond to a saturated long-chain fatty acid in a reaction catalyzed by a diiron center. The diiron center is well-coordinated by conserved histidine residues and is thought to remain with the enzyme. However, we find here that SCD1 progressively loses its activity during catalysis and becomes fully inactive after about nine turnovers. Further studies show that the inactivation of SCD1 is due to the loss of an iron (Fe) ion in the diiron center and that the addition of free ferrous ions (Fe

PURPOSE: Automation, including the use of artificial intelligence, has been identified as a possible opportunity to help reduce the gap in access and quality for radiotherapy and other aspects of cancer care. The Radiation Planning Assistant (RPA) project was conceived in 2015 (and funded in 2016) to use automated contouring and treatment planning algorithms to support the efforts of oncologists in low- and middle-income countries, allowing them to scale their efforts and treat more patients safely and efficiently (to increase access).

DESIGN: In this review, we discuss the development of the RPA, with a particular focus on clinical acceptability and …


Cisplatin Decreases Voluntary Wheel-Running Activity But Does Not Impair Food-Motivated Behavior In Mice, Kiersten S Scott, Brandon Chelette, Chinenye Chidomere, A Phillip West, Robert Dantzer Jul 2023

Cisplatin Decreases Voluntary Wheel-Running Activity But Does Not Impair Food-Motivated Behavior In Mice, Kiersten S Scott, Brandon Chelette, Chinenye Chidomere, A Phillip West, Robert Dantzer

Faculty, Staff and Student Publications

Cisplatin is a chemotherapeutic agent that is still commonly used to treat solid tumors. However, it has several toxic side effects due in large part to the mitochondrial damage that it induces. As this mitochondrial damage is likely to result in a decrease in the amount of metabolic energy that is available for behavioral activities, it is not surprising that fatigue develops in cancer patients treated with cisplatin. The present preclinical study was initiated to determine whether the detrimental effects of cisplatin were more pronounced on physical effort requiring a lot of energy versus effort that not only requires less …

Immunotherapy-Related Pneumonitis And The Synergic Impact Of Thoracic Radiation And Preexisting Interstitial Lung Disease, Maria Azhar, Rodeo Abrencillo, Saumil Gandhi, Mehmet Altan, Ajay Sheshadri

Faculty, Staff and Student Publications

PURPOSE OF REVIEW: Immune checkpoint inhibitors (ICIs) are the frontline of therapy for most cancers. Although ICIs are sometimes considered to be less harmful than systemic chemotherapies, ICIs may cause immune-related adverse events, which are cases of off-target inflammation in healthy tissues. Pneumonitis, an immune-related adverse event, is the leading cause of therapy-related mortality with ICIs. The aim of this review is to discuss how preexisting interstitial lung disease (ILD) and thoracic radiation increase the risk for ICI-pneumonitis. We discuss potential mechanisms of lung injury and how pneumonitis may impact cancer treatments.

RECENT FINDINGS: Preexisting ILD and thoracic radiation are …

Deep brain stimulation (DBS) is a promising treatment for drug-refractory epilepsies (DRE) when targeting the anterior nuclei of thalamus (ANT). However, targeting other thalamic nuclei, such as the pulvinar, shows therapeutic promise. Our pioneering case study presents the application of ambulatory seizure monitoring using spectral fingerprinting (12.15-17.15 Hz) recorded through Medtronic Percept DBS implanted bilaterally in the medial pulvinar thalami. This technology offers unprecedented opportunities for real-time monitoring of seizure burden and thalamocortical network modulation for effective seizure reduction in patients with bilateral mesial temporal and temporal plus epilepsies that are not suitable for resection.

Src Stimulates Abl-Dependent Phosphorylation Of The Guanine Exchange Factor Net1a To Promote Its Cytosolic Localization And Cell Motility, Ashabari Sprenger, Heather S Carr, Arzu Ulu, Jeffrey A Frost Jul 2023

Src Stimulates Abl-Dependent Phosphorylation Of The Guanine Exchange Factor Net1a To Promote Its Cytosolic Localization And Cell Motility, Ashabari Sprenger, Heather S Carr, Arzu Ulu, Jeffrey A Frost

Faculty, Staff and Student Publications

The neuroepithelial cell transforming gene 1 (Net1) is a guanine nucleotide exchange factor for the small GTPase RhoA that promotes cancer cell motility and metastasis. Two isoforms of Net1 exist, Net1 and Net1A, both of which are sequestered in the nucleus in quiescent cells to prevent aberrant RhoA activation. Many cell motility stimuli drive cytosolic relocalization of Net1A, but mechanisms controlling this event are not fully understood. Here, we demonstrate that epithelial growth factor stimulates protein kinase Src- and Abl1-dependent phosphorylation of Net1A to promote its cytosolic localization. We show that Abl1 efficiently phosphorylates Net1A on Y373, and that phenylalanine …

Faculty, Staff and Student Publications

BACKGROUND: Type IV collagen is an abundant component of basement membranes in all multicellular species and is essential for the extracellular scaffold supporting tissue architecture and function. Lower organisms typically have two type IV collagen genes, encoding α1 and α2 chains, in contrast with the six genes in humans, encoding α1-α6 chains. The α chains assemble into trimeric protomers, the building blocks of the type IV collagen network. The detailed evolutionary conservation of type IV collagen network remains to be studied.

RESULTS: We report on the molecular evolution of type IV collagen genes. The zebrafish α4 non-collagenous (NC1) domain, in …

Endoscopic Mucosal Resection: Tips And Tricks For Gastrointestinal Trainees, Tessa Herman, Bryant Megna, Kumar Pallav, Mohammad Bilal

Faculty, Staff and Student Publications

Endoscopic mucosal resection (EMR) is a minimally invasive, specialized endoscopic technique that is useful in resecting superficial gastrointestinal lesions that are unable to be removed by standard polypectomy. This is typically accomplished using a submucosal injection that lifts the lesion away from the muscularis propria to allow for safe resection of the polyp, either via piecemeal or en bloc resection. Over the years, several techniques exist to perform EMR including conventional EMR or hot EMR, cold EMR and underwater EMR. Despite its established advantages and safety over conventional techniques such as surgery, the adoption of endoscopic resection (and thus the …

Background: Response to neoadjuvant systemic therapy (NST) for breast cancer enables tailoring of subsequent therapy. Image-guided breast biopsy after NST can accurately predict a pathologic complete response (pCR). The feasibility phase of the clinical trial reported here assesses omission of breast surgery followed by radiotherapy in terms of local recurrence before trial expansion.

Study design: Women with unicentric, cT1-2 N0-1 M0 triple-negative (TNBC) or human epidermal growth factor receptor 2-positive breast cancer (HER2+BC) cancer with < 2 cm residual disease on post-NST imaging were eligible to enroll. If no residual invasive or in situ disease was identified by image-guided, vacuum-assisted core biopsy (VACB), breast surgery was omitted, and radiotherapy delivered. The primary endpoint for the feasibility phase was ipsilateral breast tumor recurrence at 6 months. If any recurrence occurred during the feasibility phase the trial would halt.

Results: Thirteen patients were enrolled from March 2017 to October 2018. The mean age was 60.8 years (range 51 to 75) and most patients were …

T cell-mediated hyperinflammatory responses, such as cytokine release syndrome (CRS) and immune effector cell-associated neurotoxicity syndrome (ICANS), are now well-established toxicities of chimeric antigen receptor (CAR) T cell therapy. As the field of CAR T cells advances, however, there is increasing recognition that hemophagocytic lymphohistiocytosis (HLH)-like toxicities following CAR T cell infusion are occurring broadly across patient populations and CAR T cell constructs. Importantly, these HLH-like toxicities are often not as directly associated with CRS and/or its severity as initially described. This emergent toxicity, however ill-defined, is associated with life-threatening complications, creating an urgent need for improved identification and optimal …

Pediatric patients with pulmonary hypertension (PH) receive imaging studies that use ionizing radiation (radiation) such as computed tomography (CT) and cardiac catheterization to guide clinical care. Radiation exposure is associated with increased cancer risk. It is unknown how much radiation pediatric PH patients receive. The objective of this study is to quantify radiation received from imaging and compute associated lifetime cancer risks for pediatric patients with PH. Electronic health records between 2012 and 2022 were reviewed and radiation dose data were extracted. Organ doses were estimated using Monte Carlo modeling. Cancer risks for each patient were calculated from accumulated exposures …

Compressive neuropathies of the upper extremity are among the most common conditions seen by hand surgeons. The diagnoses of carpal tunnel syndrome and cubital tunnel syndrome have traditionally been made by a combination of history, physical examination, and electrodiagnostic testing. However, findings can be nonspecific and electrodiagnostic testing is invasive for the patient. The diagnosis of compressive neuropathies continues to evolve as technology advances, and newer diagnostic modalities predominantly focus on preoperative diagnostic imaging with ultrasound and magnetic resonance imaging/neurography. With the advent of cheaper, faster, and less invasive imaging, the future may bring a paradigm shift away from electrophysiology …
