Comparison Of Short-Arm Immobilization And Long-Arm Immobilization In Conservatively Managed Distal Radius Fractures: A Meta-Analysis And Systematic Review., Yash P Chaudhry, Genoveffa R Morway, Efstratios A Papadelis, Nikki A Doerr, Kenneth W Graf, Rakesh P Mashru, Henry J Dolch

Orthopedic Surgery Resident Research

Distal radius fractures are often treated conservatively with immobilization. Immobilizing above the elbow limits forearm rotation, though recent literature has suggested the effects on radiographic or functional outcomes may be negligible. This systematic review and meta-analysis aimed to analyze the radiographic and functional outcome scores of distal radius fractures managed with short-arm (SA) immobilization and long-arm (LA) immobilization. An electronic systematic search was performed of the PubMed and EMBASE databases from inception to October 5, 2022. All randomized controlled trials (RCTs) involving patients with acute distal radius fractures undergoing nonoperative treatment (involving application/maintenance of immobilization) comparing above-elbow versus below-elbow constructs …

Nail-Plate Combination Treatment Of Ipsilateral Humeral Shaft And Distal Humerus Fractures - A Case Report., Mark Lagreca, Yash P Chaudhry, Thomas Falconiero, Thomas Muzzonigro, Daniel Lippe, Mitesh Shah

Orthopedic Surgery Resident Research

INTRODUCTION: Humeral shaft and distal humerus fractures have several different treatment options, including plate fixation and intramedullary nailing. Each has its own benefits, but typically, they are not used in conjunction. While nail-plate combinations (NPCs) have become more common in the lower extremity, literature on their use in upper extremity fractures remains scarce.

CASE REPORT: A 74-year-old right-hand dominant male presented after a fall with a closed left transverse midshaft humerus fracture and an associated supracondylar distal humerus fracture with intercondylar extension through a medial column. Due to the segmental nature of his injury, medial column plating was used in …

INTRODUCTION: Osteopathic manipulative medicine (OMM) encompasses techniques guided by the tenets of osteopathy aimed at facilitating the body's natural self-healing capabilities as a treatment option for injury or illness. This approach recognizes the interrelationship of structure and function in promoting overall health. The clinical applications of OMM have been highly researched throughout different subspecialties of medicine; however, there is a notable lack of osteopathic-based research targeted toward neurosurgical patient populations.

METHODS: This cross-sectional descriptive study was conducted via a survey generated using SurveyMonkey (SurveyMonkey, San Mateo, CA, USA; accessed at www.surveymonkey.com). Subjects for this survey were gathered using a convenience …

You May Delay, But Time Will Not. Beta Cells Lost Are Never Found Again, Susan Renda, Jeffrey Freeman

PCOM Scholarly Papers

Since its first use just over a century ago, insulin treatment has evolved dramatically, such that the molecules are physiologic in nature, and treatment can now closely resemble the natural hormone response over 24 hours. Newer, longer-acting basal insulin analogs have provided insulin therapies with improved characteristics and, therefore, ease of use, and can readily be incorporated as part of routine treatment for type 2 diabetes (T2D), but evidence suggests that insulin remains underused in people with T2D. We review the barriers to initiation of basal insulin and the education needed to address these barriers, and we provide practical pointers, …

No Difference In Pullout Strength Between A Bio-Inductive Implant And A Semitendinosus Tendon Graft In A Biomechanical Study Of Medial Patellofemoral Ligament Repair Augmentation., Austin Wetzler, Sean Mcmillan, Erik Brewer, Aakash Patel, Samuel Handy, Merrick Wetzler

Orthopedic Surgery Resident Research

PURPOSE: To compare the pullout strength of a bio-inductive implant (BI) used to augment a medial patellofemoral ligament (MPFL) repair with the pullout strength of semitendinosus graft in a biomechanical cadaveric model.

METHODS: Six matched pairs of cadavers (12 knees) were used in the biomechanical testing comparing semitendinosus tendon (Semi-T) versus a BI. The Semi-T was harvested from 1 of the matched pairs. A standard double-bundle technique using 2 sockets in the upper two-thirds of the patella 15 mm apart was performed. After docking of the graft into the patella, the patella was dissected free of soft tissues and potted …

From Sabers To Spikes: A Newfangled Reconstruction Of The Ancient, Giant, Sexually Dimorphic Pacific Salmon, †Oncorhynchus Rastrosus (Salmoninae: Salmonini)., Kerin M. Claeson, Brian L Sidlauskas, Ray Troll, Zabrina M Prescott, Edward B Davis

PCOM Scholarly Papers

The impressive †Oncorhynchus rastrosus of the Pacific Northwest's Miocene and Pliocene eras was the largest salmonid ever to live. It sported a hypertrophied premaxilla with a pair of enlarged teeth which the original describers reconstructed as projecting ventrally into the mouth, leading them to assign the species to "Smilodonichthys," a genus now in synonymy. Through CT reconstruction of the holotype and newly collected specimens, we demonstrate that the famed teeth projected laterally like tusks, not ventrally like sabers or fangs. We also expand the original description to characterize sexual dimorphism in mature, breeding individuals. Male and female †Oncorhynchus rastrosus differ …

Tislelizumab With Gemcitabine And Cisplatin As A Neoadjuvant Regimen For Muscle-Invasive Bladder Cancer: Case Series., Ze Wang, Yapeng Wang, Shuo Wang, Qiang Ran, Song Peng, Yao Zhang, Jun Zhang, Dianzheng Zhang, Luofu Wang, Weihua Lan, Qiuli Liu, Jun Jiang

PCOM Scholarly Papers

INTRODUCTION AND IMPORTANCE: The feasibility of combined tislelizumab with gemcitabine and cisplatin as a neoadjuvant regimen for muscle-invasive bladder cancer (MIBC) remains to be investigated.

CASE PRESENTATION: The neoadjuvant treatment not only shrunk tumours significantly but also lowered their stages from T4bN1M0, T3N0M0, and T3bN0M0 to pT1, pT0 and pTis, respectively. The treatment suppressed tumour cell proliferation and promoted luminal-to-basal transition.

CLINICAL DISCUSSION: MIBC is an aggressive bladder cancer with poor prognosis. All three patients with MIBC benefited greatly from the neoadjuvant regimen (tislelizumab + gemcitabine + cisplatin). It appears that the effect of the treatment is independent of the …

Multiple myeloma (MM) is characterized by the accumulation of malignant plasma cells preferentially in the bone marrow. Currently, emerging chemotherapy drugs with improved biosafety profiles, such as immunomodulatory agents and protease inhibitors, have been used in clinics to treat MM in both initial therapy or maintenance therapy post autologous hematopoietic stem cell transplantation (ASCT). We previously discovered that caffeic acid phenethyl ester (CAPE), a water-insoluble natural compound, inhibited the growth of MM cells by inducing oxidative stress. As part of our continuous effort to pursue a less toxic yet more effective therapeutic approach for MM, the objective of this study …

Postoperative Stomach Volvulus And Pancreatitis Following A Sleeve Gastrectomy., Shane B Devine, Sam J King, Bradley J Chatterton, Kurt D Knepley

Internal Medicine Resident Research

The laparoscopic sleeve gastrectomy is the most common bariatric surgery performed to promote weight loss and improve obesity-related comorbidities. As the number of patients undergoing sleeve gastrectomy increases, so does the prevalence of complications. It is crucial to recognize both common and unusual complications of sleeve gastrectomy to properly diagnose and manage them. We present a unique case of gastric outlet obstruction not visualized on initial imaging and acute pancreatitis following a sleeve gastrectomy. We recommend performing an endoscopy and ordering serum lipase levels in a patient with negative CT scans but persistent postoperative nausea, vomiting, and abdominal pain. The …

PCOM Scholarly Papers

BACKGROUND: Awareness with paralysis (AWP) is memory recall during neuromuscular blockade (NMB) and can cause significant psychological harm. Decades of effort and rigorous trials have been conducted to prevent AWP in the operating room, where prevalence is 0.1-0.2%. By contrast, AWP in mechanically ventilated emergency department (ED) patients is common, with estimated prevalence of 3.3-7.4% among survivors given NMB. Longer-acting NMB use is a critical risk for AWP, and we have shown an association between ED rocuronium use and increased AWP prevalence. As NMB are given to more than 90% of ED patients during tracheal intubation, this trial provides a …

Aberrant Mitochondrial Dynamics Contributes To Diaphragmatic Weakness Induced By Mechanical Ventilation., Haikel Dridi, Marc Yehya, Robert J. Barsotti, Yang Liu, Steven Reiken, Lan Azria, Qi Yuan, Laith Bahlouli, Rajesh Kumar Soni, Andrew R Marks, Alain Lacampagne, Stefan Matecki

PCOM Scholarly Papers

In critical care patients, the “”temporary inactivity of the diaphragm caused by mechanical ventilation (MV) triggers a series of events leading to diaphragmatic dysfunction and atrophy, commonly known as ventilator-induced diaphragm dysfunction (VIDD). While mitochondrial dysfunction related to oxidative stress is recognized as a crucial factor in VIDD, the exact molecular mechanism remains poorly understood. In this study, we observe that 6 h of MV triggers aberrant mitochondrial dynamics, resulting in a reduction in mitochondrial size and interaction, associated with increased expression of dynamin-related protein 1 (DRP1). This effect can be prevented by P110, a molecule that inhibits the recruitment …

Spinal and bulbar muscular atrophy (SBMA) is a neuromuscular disease with substantial mitochondrial and metabolic dysfunctions. SBMA is caused by polyglutamine (polyQ) expansion in the androgen receptor (AR). Activating or increasing the NAD^+-dependent deacetylase, SIRT3, reduced oxidative stress and death of cells modeling SBMA. However, increasing diminished SIRT3 in AR100Q mice failed to reduce acetylation of the SIRT3 target/antioxidant, SOD2, and had no effect on increased total acetylated peptides in quadriceps. Yet, overexpressing SIRT3 resulted in a trend of motor recovery, and corrected TCA cycle activity by decreasing acetylation of SIRT3 target proteins. We sought to boost blunted …

Atypical Intraparenchymal Meningioma With Yap1-Maml2 Fusion In A Young Adult Male: A Case Report And Mini Literature Review., Alisa Nobee, Mei Xu, Anjali Seth, Yuan Rong

PCOM Scholarly Papers

Oncogenic Yes-associated protein (YAP) 1 fusions have been recently identified in several cases of meningioma mostly involving pediatric patients. The meningiomas harboring YAP1-MAML2, which is the most frequent fusion subtype, exhibit activated YAP1 signaling and share similarities with NF2 (neurofibromatosis type 2 gene) mutant meningiomas. We reported a rare case of atypical intraparenchymal meningioma with YAP1-MAML2 fusion in a 20-year-old male. The patient presented with an episode of seizure without a medical history. MRI revealed a lesion in the right temporal lobe without extra-axial involvement. The radiological and morphological findings, however, were indistinctive from other intracranial diseases, e.g., vascular malformation …

Cytotoxic And Apoptotic Effects Of Pinostilbene And Bortezomib Combination Treatment On Human Multiple Myeloma Cells., Anna Staskiewicz, Erica Wong, Michael Tucker, Riya Farhin, Jonathan Park, Rana Saade, Tina Alkhazali, Tu Dang, Xinyu Wang

PCOM Scholarly Papers

Multiple myeloma (MM) is a cancer of plasma cells in the bone marrow characterized by bone lesions, hypercalcemia, anemia, and renal failure. Bortezomib (BTZ), a common treatment for MM, is a proteasome inhibitor that induces apoptosis in MM cells. However, high doses of BTZ can be very toxic, signifying a need for a synergistic drug combination to improve treatment efficacy. Resveratrol (RES), a phenolic compound found in grapes, has been shown to inhibit MM cell growth. We sought to identify a synergistic combination of BTZ with a RES derivative and analyze the effects on reducing viability and inducing apoptosis in …

Phf8-Glul Axis In Lipid Deposition And Tumor Growth Of Clear Cell Renal Cell Carcinoma., Song Peng, Ze Wang, Peng Tang, Shuo Wang, Yiqiang Huang, Qiubo Xie, Yapeng Wang, Xintao Tan, Tang Tang, Xuzhi Yan, Jing Xu, Weihua Lan, Luofu Wang, Dianzheng Zhang, Bin Wang, Tiejun Pan, Jun Qin, Jun Jiang, Qiuli Liu

PCOM Scholarly Papers

For clear cell renal cell carcinoma (ccRCC), lipid deposition plays important roles in the development, metastasis, and drug resistance. However, the molecular mechanisms underlying lipid deposition in ccRCC remain largely unknown. By conducting an unbiased CRISPR-Cas9 screening, we identified the epigenetic regulator plant homeodomain finger protein 8 (PHF8) as an important regulator in ccRCC lipid deposition. Moreover, PHF8 is regulated by von Hippel-Lindau (VHL)/hypoxia-inducible factor (HIF) axis and essential for VHL deficiency-induced lipid deposition. PHF8 transcriptionally up-regulates glutamate-ammonia ligase (GLUL), which promotes the lipid deposition and ccRCC progression. Mechanistically, by forming a complex with c-MYC, PHF8 up-regulates TEA domain transcription …

Chemotherapy-related cognitive impairment (CRCI) or "chemo brain" is a devastating neurotoxic sequela of cancer-related treatments, especially for the elderly individuals. Here we show that PTPRO, a tyrosine phosphatase, is highly enriched in the hippocampus, and its level is tightly associated with neurocognitive function but declined significantly during aging. To understand the protective role of PTPRO in CRCI, a mouse model was generated by treating Ptpro-/- female mice with doxorubicin (DOX) because Ptpro-/- female mice are more vulnerable to DOX, showing cognitive impairments and neurodegeneration. By analyzing PTPRO substrates that are neurocognition-associated tyrosine kinases, we found that SRC and EPHA4 are …
