The Attitudes, Level Of Interest, And Knowledge Held By Physicians And Psychologists Toward Integrated Healthcare Practices And The Patient-Centered Medical Home Model, Mark Cassano, Robert A. Ditomasso, Barbara Golden, Scott D. Glassman

The Journal of Integrated Primary Care

As the healthcare system evolves, issues related to cost and access to care continue to persist. In response to this concern, integrated models of healthcare, like the Patient-Centered Medical Home (PCMH), have been developed to work toward reducing cost for both patients and providers, increasing patient access to quality care, and improving patients’ overall satisfaction with the care that they are provided. However, despite the overwhelming evidence found in the literature supporting the efficacy and benefit of these treatment models, it is unclear as to why more providers do not choose to practice and support collaborative forms of healthcare provision. …

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 …

End Of Life In The Ed – Brain Death And Organ Transplantation, Madison Cohen, Donald Penney

The Journal of Integrated Primary Care

Every year thousands of Americans die awaiting an organ transplant. While our knowledge and experience with organ transplantation has only improved, organ availability continues to be a major issue due to a lack of suitable donor organs. A large population of organ donors are those who have been clinically diagnosed as brain dead. Brain death is defined as the irreversible loss of all brain and brainstem functions. Despite brainstem functions being lost, mechanical ventilation and perfusion techniques allow for proper organ maintenance. This gives brain-dead individuals a unique opportunity to serve as multiple organ donors. However, due to mistrust of …

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 …

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 …
