Overcoming CEP85L-ROS1, MKRN1-BRAF and MET amplification as rare, acquired resistance mutations to Osimertinib.

Lung cancer is the most common cancer-related cause of death worldwide, most of which are non-small cell lung cancers (NSCLC). Epidermal growth factor receptor (EGFR) mutations are common drivers of NSCLC. Treatment plans for NSCLC, specifically adenocarcinomas, rely heavily on the presence or absence of specific actionable driver mutations. Liquid biopsy can guide the treatment protocol to detect the presence of various mechanisms of resistance to treatment. We report three NSCLC EGFR mutated cases, each treated with Osimertinib in a combination therapy regimen to combat resistance mechanisms. The first patient presented with EGFR L858R/L833V compound mutation with MET amplification alongside CEP85L-ROS1 fusion gene, the second with EGFR exon 19del and MKRN1-BRAF fusion, and the last EGFR L858R/V834L compound mutation with MET amplification. Each regimen utilized a tyrosine kinase inhibitor or monoclonal antibody in addition to osimertinib and allowed for a prompt and relatively durable treatment response.

COVID-19 Vaccination Among the Arab Bedouin Population: Lessons Learned From a Minority Population.

Objectives: We investigated the causes of low COVID-19 vaccination rates among a minority population and highlighted interventions for increasing the vaccination rate. Methods: We reviewed the experience during the mass vaccination campaign period among the Arab Bedouin (AB) in Israel, attempting to determine important causes of low vaccination rates and gathered information from real-life experience and through direct contact with the population during the campaign. Results: Causes for low vaccination rates in the AB are related to the health system infrastructure, crisis management strategies, and population characteristics. Long-standing socioeconomic inequalities, limited resources, and language and culture barriers present special challenges to the task of COVID-19 vaccination campaigns. Key interventions for increasing vaccination rates among minority populations include raising awareness, improving vaccination access, and directly targeting risk-groups. To maximize the effectiveness of these interventions they should be culturally adapted and executed according to the needs of each individual target community. Conclusion: Culturally adapted awareness campaigns, interventions, and improved access to vaccines can be accomplished by cooperation between relevant governing and community bodies to increase COVID-19 vaccination rates among minorities.
