Experiences of disabled students in undergraduate medical education.

PURPOSE: Since people with disabilities (PwD) are underrepresented in medical education, the authors of this article conducted a qualitative research in the form of an in-depth interview with students with disabilities from a medical school in Brazil, to characterize their experiences in medical education and identify barriers and facilitators to inclusion. MATERIALS AND METHODS: Participants were recruited by snowball sampling, signed an informed consent form, and completed a socioeconomic questionnaire. They were interviewed individually with open-ended questions so that they could develop narratives. RESULTS: The students identified some barriers to inclusion - teachers' lack of knowledge about students' special needs, students' own lack of knowledge about their needs during the medical course, underestimation of the disability by teachers and classmates, difficult access to college buildings - and facilitators, such as acceptance of the disability by professors and colleagues, proactivity of professors and colleagues in adapting practical learning scenarios. CONCLUSION: Students identified peer and teacher acceptance as an important determinant of inclusion, which is in line with the biopsychosocial view of disability. They also reported doubts about their ability to practice medicine, which dialogues with literature research that points to a medical culture that expects nothing less than perfection from students.

COVID-19 Vaccinations: Summary Guidance for Cancer Patients in 28 Languages: Breaking Barriers to Cancer Patient Information.

BACKGROUND: Covid-19 vaccination has started in the majority of the countries at the global level. Cancer patients are at high risk for infection, serious illness, and death from COVID-19 and need vaccination guidance and support. Guidance availability in the English language only is a major limit for recommendations' delivery and their application in the world's population and generates information inequalities across the different populations. METHODS: Most of the available COVID-19 vaccination guidance for cancer patients was screened and scrutinized by the European Cancer Patients Coalition (ECPC) and an international oncology panel of 52 physicians from 33 countries. RESULTS: A summary guidance was developed and provided in 28 languages in order to reach more than 70 percent of the global population. CONCLUSION: Language barrier and e-guidance availability in the native language are the most important barriers when communicating with patients. E-guidance availability in various native languages should be considered a major priority by international medical and health organizations that are communicating with patients at the global level.

Current and potential biomarkers in gastric cancer: a critical review of the literature.

Gastric cancer is the fourth most common type of cancer worldwide and the second most lethal. Gastric cancer biomarkers can be used for diagnosis, prediction of sensitivity to treatment, and prognosis. The following search terms were applied to PubMed as of December 2020: 'gastric cancer classification', 'gastric cancer epidemiology', 'cancer metastasis' and 'gastric cancer biomarker'. Only experimental studies were reported in the 'biomarkers' section. Some biomarkers can serve as therapeutic targets for antitumoral drugs. The genes analyzed include E-cadherin, RPRM, XAF1, MINT25, TFF1, p16 and p53. The miRNAs analyzed include miR-18a, miR185-5p, miR-125b and miR-21. Some molecules were associated with metastasis of gastric cancer, specifically those involved with EMT process and tissue degradation.

Lay abstract Gastric cancer is the fourth most common type of cancer worldwide and the second most lethal. Gastric cancer biomarkers are molecules that have different expressions in tumor cells than in normal body cells, and can be used for diagnosis, prediction of sensitivity to treatment, and prognosis. Biomarkers in gastric cancer can include genes that suppress tumor progression, genes that increase tumor progression by binding to growth molecules, molecules related to the body's immune response to the tumor, and non-coding RNA molecules (RNA molecules that do not produce proteins but regulate the cell's genetic material). Some biomarkers can serve as therapeutic targets for anti-tumoral drugs.

Immunotherapy in Patients with Advanced Non-Small Cell Lung Cancer Lacking Driver Mutations and Future Perspectives.

From a complete literature review, we were able to present in this paper what is most current in the treatment with immunotherapy for advanced non-small cell lung cancer (NSCLC). Especially the use of immunotherapy, particularly inhibitors of PD-1 (programmed cell death protein 1), PDL-1 (programmed cell death protein ligand 1), and CTLA-4 (cytotoxic T-lymphocyte antigen 4). Since 2015, these drugs have transformed the treatment of advanced NSCLC lacking driver mutations, evolving from second-line therapy to first-line, with excellent results. The arrival of new checkpoint inhibitors such as cemiplimab and the use of checkpoint inhibitors earlier in the therapy of advanced and metastatic cancers has been making the future prospects for treating NSCLC lacking driver mutations more favorable and optimistic. In addition, for those patients who have low PDL-1 positivity tumors, the combination of cytotoxic chemotherapy, VEGF inhibitor, and immunotherapy have shown an important improvement in global survival and progression free survival regardless the PDL-1 status. We also explored the effectiveness of adding radiotherapy to immunotherapy and the most current results about this combination. One concern that cannot be overlooked is the safety profile of immune checkpoint inhibitors (ICI) and the most common toxicities are described throughout this paper as well as tumor resistance to ICI.

New Target Therapies in Advanced Non-Small Cell Lung Cancer: A Review of the Literature and Future Perspectives.

INTRODUCTION: Lung cancer (LC) is the most common neoplasm worldwide, and 85% of these tumors are classified as non-small cell lung cancer (NSCLC). LC treatment was initially restricted to cytotoxic chemotherapy-platinum compounds associated with 3rd generation cytotoxic agents (paclitaxel, gemcitabine, pemetrexed) and, more recently, with monoclonal antibodies (bevacizumab, ramucirumab). Advancements in treatment are correlated with prolonged overall survival (OS). Current advances are focused on target therapies. Target agents: Anti-epidermal growth factor receptor (EGFR) therapy consists of 1st and 2nd generation tyrosine kinase inhibitors (TKIs such as erlotinib, afatinib). In 60% of cases, resistance to these TKIs occurs due to T790M mutation in EGFR, which is overcome 3rd generation drugs (osimertinib). Anaplastic lymphoma kinase (ALK) is the target for drugs such as crizotinib, alectinib, ceritinib. Programmed death 1 (PD-1) and its ligand serve as targets for immunotherapy agents such as pembrolizumab, nivolumab, atezolizumab. DISCUSSION: Challenges in NSCLC treatment include resistance to 3rd generation TKIs, the high cost of ALK inhibitors, and the need for further research on new drugs.

Biomarkers for Non-Small Cell Lung Cancer: From the Bench to the Bedside.

Lung cancer (LC) is inarguably one of the biggest battles to be fought in the field of oncology, and non-small cell lung cancer accounts for over 85% of all lung cancer cases [...].

The Role of MET Inhibitor Therapies in the Treatment of Advanced Non-Small Cell Lung Cancer.

Introduction: Non-small cell lung cancer (NSCLC) is the second most common cancer globally. The mesenchymal-epithelial transition (MET) proto-oncogene can be targeted in NSCLC patients. Methods: We performed a literature search on PubMed in December 2019 for studies on MET inhibitors and NSCLC. Phase II and III clinical trials published in English between 2014 and 2019 were selected. Results: Data on MET inhibitors (tivantinib, cabozantinib, and crizotinib) and anti-MET antibodies (emibetuzumab and onartuzumab) are reported in the text. Conclusion: Emibetuzumab could be used for NSCLC cases with high MET expression. Further, studies on onartuzumab failed to prove its efficacy, while the results of tivantinib trials were clinically but not statistically significant. Additionally, cabozantinib was effective, but adverse reactions were common, and crizotinib was generally well-tolerated.
