Cancer immunotherapy is a type of treatment that harnesses the power of the immune systems of patients to target cancer cells with better precision compared to traditional chemotherapy. Several lines of treatment have been approved by the US Food and Drug Administration (FDA) and have led to remarkable success in the treatment of solid tumors, such as melanoma and small-cell lung cancer. These immunotherapies include checkpoint inhibitors, cytokines, and vaccines, while the chimeric antigen receptor (CAR) T-cell treatment has shown better responses in hematological malignancies. Despite these breakthrough achievements, the response to treatment has been variable among patients, and only a small percentage of cancer patients gained from this treatment, depending on the histological type of tumor and other host factors. Cancer cells develop mechanisms to avoid interacting with immune cells in these circumstances, which has an adverse effect on how effectively they react to therapy. These mechanisms arise either due to intrinsic factors within cancer cells or due other cells within the tumor microenvironment (TME). When this scenario is used in a therapeutic setting, the term “resistance to immunotherapy” is applied; “primary resistance” denotes a failure to respond to treatment from the start, and “secondary resistance” denotes a relapse following the initial response to immunotherapy. Here, we provide a thorough summary of the internal and external mechanisms underlying tumor resistance to immunotherapy. Furthermore, a variety of immunotherapies are briefly discussed, along with recent developments that have been employed to prevent relapses following treatment, with a focus on upcoming initiatives to improve the efficacy of immunotherapy for cancer patients.
BackgroundThe decrease in the number of adolescents showing genuine interest in the fields of healthcare has been one of the recent concerns worldwide. A plethora of studies have discussed the factors that influence career choices of high school students, including science educational pedagogies, gender, environment, the student’s cognitive capabilities, and social perceptions of occupations being gender-based. As reported in 2012, a majority of the Qatari high-school students have shown a greater interest in business, technological, and administrative careers and a lower interest in healthcare. Comprehensive national and institutional strategies have since been utilized to direct the interest of Qatari generation toward healthcare careers.ObjectiveThe primary objective of this case-control study is to assess the effect of schooling type on the enrollment in the Empower Generations (EG) career training in healthcare at the Qatar University. The secondary objectives are: (1) to describe the effect of initial career interest on the EG and healthcare majors composite’s enrollments and (2) assess the association between the history of enrollment in EG and university GPAs.MethodThis is a case-control study that utilized the Qatar University’s enrollment databases for the health professions majors, that is, Health Sciences, Medicine, Pharmacy, and Dentistry. The datasets were collected from the registration records between 2013 and 2020. The statistical analysis was performed on the Statistical Package for the Social Sciences (SPSS) software version 26; the study used Chi-Square Test and Independence and logistic regression to assess the effect of schooling type and initial career interest on the enrollment in the EG training at the Qatar University. All statistics were tested for p = 0.05 and 95% CI.ResultsTotal QU-Health records of admissions from 2013 to 2020 involve 562 eligible students. A total of 180 students (32%) attended EG training before they were admitted to QU-Health, whereas a total of 382 (68%) were enrolled to QU-Health without attending EG training. The study revealed significant findings regarding the association between EG training and international schools (p < 0.001). Among the group who attended EG training, there were 63 students (75%) who reported that they did not have an initial career interest before they joined the EG training compared to 21 students (25%) reported that they did not have an initial career interest but enrolled immediately to healthcare majors. The findings indicate insignificant association between the history of EG training and the high school percentage p = 0.397. However, the association between a history of EG training and the university’s GPA is significant, with a p < 0.001, OR 5.016 (2.954–8.518).ConclusionThe study has shown significant association between the EG training enrollment and the type of school and the initial career interest of high school students. The EG training is perceived to direct the interest of high school students toward the careers of healthcare and is thought to enhance the performance of college students through their university’s GPAs.
The clinical practicum for biomedical science students aims to provide graduates with the knowledge and skills required to work in diagnostic laboratory settings. This study examines graduates’ perspectives on content, teachers and clinical training and their satisfaction rates based on the skills gained during training. The study was conducted on females who graduated from Qatar University between 2015 and 2020. We used a previously validated questionnaire called CPAT-QU. Telephonic interviews were conducted and were analyzed using SPSS. The results showed a high satisfaction rate, of 80%, for the content and organization of the clinical training. The participants’ main concerns included the evaluation criteria, as 8.7% were not satisfied. The students suggested increasing the length of the training in order to obtain experience that was more practical. The students’ satisfaction with the teachers was 70% in terms of their attitude, command of knowledge and ability to convey knowledge. In total, 69.5% of the graduates claimed that their instructors were interested in teaching and 4.4% claimed their instructors conveyed disinterest in teaching. The Qatar University graduates were satisfied with the content of their clinical training. However, they reported some gaps in this training. Identifying these gaps will help in restructuring clinical training to improve student experience.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
