McTFI QSM MRI ABC/2 intracranial hemorrhage to noncontrast head CT volume measurement equivalence

Background/objectivesIntracranial hemorrhage (ICH) volume assessment is an important part of patient management and is routinely obtained by non-contrast head CT (NCHCT) using the validated ABC/2 measurement method. Because conventional MRI imaging sequences demonstrate variability in ICH appearance, volumetric analyses for MRI bleed volume in a standardized manner using ABC/2 is not possible. The recently introduced multiecho-complex total field inversion quantitative susceptibility mapping (mcTFI QSM) MRI technique, which maps brain tissue susceptibility to both depict brain tissue structures and quantify tissue susceptibility, may provide a viable alternative. In this study we evaluated mcTFI QSM ABC/2 ICH volume assessment relative to NCHCT. MethodsPatients with ICH who had undergone NCHCT and MRI brain scans within 48 h were recruited for this retrospective study. The ABC/2 method was applied to estimate the bleed volume for both NCHCT and MRI by a CAQ-certified neuroradiologist with 10 years of experience and a trained laboratory assistant. Results were analyzed via Bland-Altman (B-A) and linear regression. Results54 patients (27 females) who had undergone NCHCT and MRI within 48 h (<24 h., n = 31, 24-48 h, n = 10) were enrolled. mcTFI QSM ICH volume measurement method showed a positive correlation (99.5%) compared to NCHCT. B-A plot comparing ABC/2 ICH volume on NCHCT and mcTFI MRI done for patients within 24 h demonstrates a bias of −0.09%. ConclusionsICH volume calculation using ABC/2 on mcTFI QSM showed a high correlation with NCHCT measurement. These results suggest mcTFI QSM is a promising MRI method for ABC/2 for bleed volume measurement.

Computer models as a means of improving the effectiveness of teaching physics

Computer models and programs are one of the main tools in education, therefore, the development of a plan for their development and use in the field of education is one of the main problems. The use of computer models will help to explore a new topic, a demonstration experiment and phenomena without violating safety regulations. Many experts believe that the computer currently makes it possible to make a qualitative breakthrough in the education system. Models of physical phenomena and experiments actively shape students' knowledge. In teaching a number of sections of the physics course, such as atomic and nuclear physics, quantum mechanics, and elementary particle physics, essential questions about conducting experiments are obvious. These sections relate to important areas of physics that deal with the study of phenomena and processes in the microcosm. Therefore, due to some difficulties in equipping physics classrooms, the computer acts as an assistant. In quantum physics and atomic physics, computer models are considered that help explain the phenomena under study, the course of processes, as well as methods of working with computer programs that simulate laboratory installations in this section, since physical laboratory assistants are an integral part of training. The use of computer models and programs for educational purposes gives students a unique opportunity to plunge into the world of quantum and atomic physics. This study analyzes the effectiveness of such models in the educational process, their impact on students' understanding of the basic concepts of quantum and atomic physics, and also compiles questionnaires based on these problems. The survey covers about 40 physics teachers. The work is based on the analysis of existing pedagogical experiments and research in the field of application of computer models for teaching physics. The focus is on assessing the impact of these models on the quality of knowledge and their ability to make complex concepts accessible and understandable to students. The obtained results can serve as a basis for further improvement of methods of teaching quantum and atomic physics using computer programs. The introduction of computer programs can help the student create an effective learning environment for his work at his own pace and in collaboration with the class. It can be said that the use of models of physical processes in preparing students for effective learning opens up great opportunities for creating high-quality and new forms and methods, the use of computer models of physical phenomena plays an important role. Of particular importance in the development of students' abilities to observe, think, generalize based on observed facts, and predict the course of the observed process.

Sex, Age, and Risk Group Variations among Individuals Infected with HIV, HTLV-1, and HTLV-2: Review of Data Records (1983–2017) from a Public Health Laboratory in São Paulo, Brazil

The inaugural AIDS Program in Brazil was established in São Paulo in 1983, with the Instituto Adolfo Lutz appointed for laboratory assistance. Subsequently, research on HIV infections and HIV/HTLV (HIV/HTLV-1 and HIV/HTLV-2) co-infections was conducted. This narrative review focuses on studies from the Immunology Department (1983–2017) that significantly influenced AIDS diagnosis or provided epidemiological data such as prevalence rates, sex, age, and risk factors. Twelve studies, encompassing over 8000 individuals, are discussed. During 1983–1985, nearly all AIDS cases were attributed to homosexual/bisexual men aged 31 years old. Subsequently, heterosexual men and women emerged as risk groups owing to intravenous drug use (IDU) and/or unprotected sexual intercourse with AIDS patients or multiple partners per year. From 1985 onwards, vertical transmission led to child infections. HIV/HTLV co-infection rates decreased over time, initially associated with male IDU, and in the 2010s with female IDU, and individuals aged &gt;40 years. Trends in HIV and HIV/HTLV co-infections among younger men and women (&lt;30 years of age) were observed from 2015 to 2017. The changing characteristics and risk groups for HIV and HIV/HTLV co-infections over the years underscore the necessity for ongoing public policies to prevent retrovirus transmission, particularly among adolescents and young adults.

Patient Advocate Presence Helps Poster Presenters Understand Clinical Significance of their Research and Increases Empathy

Patient advocates represent the voice of the patient community and bring a unique perspective to research. We hypothesized that including patient advocates in poster sessions allow trainees to communicate their science in lay language, have an increased understanding of the clinical impact of their work, and increase their empathy for patients. A survey was designed to assess the impact invited patient advocates had on poster presenters at our Department of Radiation Oncology Research Symposium. The two advocates, one with primary breast and primary endometrial cancer, and one with metastatic breast cancer, visited each poster to discuss the project goals and outcomes with all 16 researchers (graduate/medical students, postdoctoral fellows including medical and physics residents, laboratory assistants, and faculty). The survey included demographics, and Likert scored questions about their ease in discussing research and use of lay language, the impact of the advocate on increasing the presenter's empathy and understanding the clinical significance of their work, and future role of advocates in complementing their research. Following the poster session, 14 of 16 participants completed the survey. Respondents were 57.1% male, 57.1% younger than 30 years old, and 50% people of color. Poster presenters comprised: 35.7% Graduate/Medical Students, 42.9% Medical/Physics Residents or Postdoctoral Fellows, 14% Faculty, and 7% laboratory assistants. All respondents agreed/strongly agreed they were comfortable talking to advocates. Overall, 42.8% of participants strongly agreed that they could talk to the patient advocate in lay language. 85.7% agreed/strongly agreed that their empathy for patients increased by this interaction. Although 92.9% of poster presenters believed patient advocates were able to help them understand the clinical impact of their research and 71.4% believed advocates helped them think of ideas to complement their research, 57.1% did not believe advocates could help them identify novel research conclusions. Most respondents would like advocates at future poster presentations (92.9%), but were not as sure and they would like advocates participating in study design or data analysis. Women, people of color, and graduate/medical students were most comfortable communicating in lay language, believed advocates increased their empathy and understanding of the clinical significance of their work. Patient advocates in poster sessions help trainees communicate their science, increase their empathy and understanding of the clinical impact of their research. Workshops should be considered to help young scientists communicate their science in lay language. Future radiation oncology training should consider including the patient advocate voice to improve the tangible connection between research and real-world impact.
