Dental students' Myers-Briggs Type Indicator personality profile in the past 50 years: Systematic review and meta-analysis.

BACKGROUND: Dental students' personalities are strongly correlated with their didactic and clinical performances. With the significant changes in the social environment in the past decades, students' personalities may also change dramatically. Additionally, with the increasing number of international students admitted into US dental programs, educators must pay attention to the potential personality differences between domestic and international students. BACKGROUND: A systematic review focusing on the Myers-Briggs Type Indicator personality types of dental students was conducted with 11 literature databases following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guideline. The quality assessment of each included article was conducted following the Joanna Briggs Institute Prevalence Critical Appraisal Tool. Meta-analyses were conducted for each personality type within the United States in the past 50 years, and in each country in the past 20 years. RESULTS: Eighteen articles (17 reports) were included after the eligibility assessment. The longitudinal trends within the United States showed the predominant two personality types have changed from Extraversion, Sensing, Feeling, and Judging (ESFJ) and Extraversion, Sensing, Thinking, and Judging (ESTJ) to ESTJ and Introversion, Sensing, Thinking, and Judging (ISTJ) during the past 50 years. When comparing different countries, the United States, China, Korea, and Iran have the same two dominant personality types (ESTJ and ISTJ) but not the Philippines (Extraversion, Intuition, Feeling, and Perceiving and Introversion, Intuition, Feeling, and Perceiving). However, there are large variations in the prevalence of other personality types. CONCLUSION: There have been constant changes in the predominant personalities of dental students over the years. Additionally, understanding the diversity of personality types within the United States as well as among different countries could serve as the foundation for further improvements in teaching strategies and student support services.

How good is the Myers-Briggs Type Indicator for predicting leadership-related behaviors?

The Myers-Briggs Type Indicator (MBTI) is a popular tool used by psychologists working as managers' coaches in organizational contexts. Despite its popularity, few studies provide empirical evidence on the role of the MBTI as a predictor of managers' leadership-related behaviors. This article is written based on research that answers the question of how good the MBTI is to prove leadership behavior. It does so by comparing goodness-of-fit indexes of two confirmatory factor analysis models and two structural models on the personality-leadership relationship, following standards of reproducible research principles. We sampled 529 participants who were graduate and undergraduate students enrolled in business administration programs from Colombian universities. Results show conclusive evidence of the psychometric measurement of both MBTI and leadership practices, even though the relationship between MBTI and the leadership practices inventory proved to be weak.

Personality assessment usage and mental health among Chinese adolescents: A sequential mediation model of the Barnum effect and ego identity.

Introduction: Adolescence is a crucial period for establishing ego identity and becoming a social individual. However, numerous adolescents suffer from mental health problems, especially after the conditions surrounding the COVID-19 outbreak. Personality assessments are often used when adolescents look for psychological self-help services. However, the meaning and mechanism of these personality assessments remain unknown. Taking the increasingly popular MBTI personality assessment as an entry point, the current study examined the potential sequential mediation relationship of Barnum effect - ego identity on the link between personality assessment usage and mental health. Methods: The current study surveyed 308 Chinese high school students, including 109 males and 199 females. MBTI use, Barnum effect, ego-identity, and mental health (subjective well-being, depression, and anxiety) were measured by seven questionnaires, respectively. Sequential mediation models were constructed to analyze the relationship. Results: The results indicate that the Barnum effect and ego identity together function as a sequential mediation path between personality assessment use and teenagers' mental health, including subjective well-being, depression, and anxiety. Specifically, a higher level of MBTI use triggers a stronger Barnum effect. The Barnum effect then promotes adolescents' ego identity, ultimately increasing subjective well-being levels and reducing anxiety and depression. Discussion: Our findings suggest that by properly using personality assessment and stimulating the Barnum effect, we can enhance adolescents' mental health. The theoretical and practical implications of our findings are discussed.

Approaches for targeting the mycobactin biosynthesis pathway for novel anti-tubercular drug discovery: where we stand.

INTRODUCTION: Several decades of antitubercular drug discovery efforts have focused on novel antitubercular chemotherapies. However, recent efforts have greatly shifted toward countering extremely/multi/total drug-resistant species. Targeting the conditionally essential elements inside Mycobacterium is a relatively new approach against tuberculosis and has received lackluster attention. The siderophore, Mycobactin, is a conditionally essential molecule expressed by mycobacteria in iron-stress conditions. It helps capture the micronutrient iron, essential for the smooth functioning of cellular processes. AREAS COVERED: The authors discuss opportunities to target the conditionally essential pathways to help develop newer drugs and prolong the shelf life of existing therapeutics, emphasizing the bottlenecks in fast-tracking antitubercular drug discovery. EXPERT OPINION: While the lack of iron supply can cripple bacterial growth and multiplication, excess iron can cause oxidative overload. Constant up-regulation can strain the bacterial synthetic machinery, further slowing its growth. Mycobactin synthesis is tightly controlled by a genetically conserved mega enzyme family via up-regulation (HupB) or down-regulation (IdeR) based on iron availability in its microenvironment. Furthermore, the recycling of siderophores by the MmpL-MmpS4/5 orchestra provides endogenous drug targets to beat the bugs with iron-toxicity contrivance. These processes can be exploited as chinks in the armor of Mycobacterium and be used for new drug development.

A credit scoring model based on the Myers-Briggs type indicator in online peer-to-peer lending.

Although psychometric features have been considered for alternative credit scoring, they have not yet been applied to peer-to-peer (P2P) lending because such information is not available on platforms. This study proposed an alternative credit scoring model for P2P lending by extracting typical personality types inferred from the borrowers' job category. We projected a virtual space of borrowers by using the affinity matrix based on the Myers-Briggs type indicator (MBTI) that fits each job category. Applying the distance in this space to Lending Club data, we used locally weighted logistic regression to vary the coefficients of the variables, which affect loan repayments, with each MBTI type for predicting the default probability. We found that each MBTI type's credit scoring model has different significant variables. This study provides insights into breakthroughs in developing alternative credit scoring for P2P lending.

Predicting judging-perceiving of Myers-Briggs Type Indicator (MBTI) in online social forum.

The Myers-Briggs Type Indicator (MBTI) is a well-known personality test that assigns a personality type to a user by using four traits dichotomies. For many years, people have used MBTI as an instrument to develop self-awareness and to guide their personal decisions. Previous researches have good successes in predicting Extraversion-Introversion (E/I), Sensing-Intuition (S/N) and Thinking-Feeling (T/F) dichotomies from textual data but struggled to do so with Judging-Perceiving (J/P) dichotomy. J/P dichotomy in MBTI is a non-separable part of MBTI that have significant inference on human behavior, perception and decision towards their surroundings. It is an assessment on how someone interacts with the world when making decision. This research was set out to evaluate the performance of the individual features and classifiers for J/P dichotomy in personality computing. At the end, data leakage was found in dataset originating from the Personality Forum Café, which was used in recent researches. The results obtained from the previous research on this dataset were suggested to be overly optimistic. Using the same settings, this research managed to outperform previous researches. Five machine learning algorithms were compared, and LightGBM model was recommended for the task of predicting J/P dichotomy in MBTI personality computing.

Motivating Adherence to Exercise Plans Through a Personalized Mobile Health App: Enhanced Action Design Research Approach.

BACKGROUND: Physical inactivity is a global issue that affects people's health and productivity. With the advancement of mobile technologies, many apps have been developed to facilitate health self-management. However, few studies have examined the effectiveness of these mobile health (mHealth) apps in motivating exercise adherence. OBJECTIVE: This study aims to demonstrate the enhanced action design research (ADR) process and improve the design of mHealth apps for exercise self-management. Specifically, we investigate whether sending motivational messages improves adherence to exercise plans, whether the motivational effect is affected by personality, the impact of message type and repetition, and the process of involving a field experiment in the design process and learning new design principles from the results. METHODS: This formative research was conducted by proposing an enhanced ADR process. We incorporated a field experiment into the process to iteratively refine and evaluate the design until it converges into a final mHealth app. We used the Apple ResearchKit to develop the mHealth app and promoted it via trainers at their gyms. We targeted users who used the app for at least two months. Participants were randomly assigned to 1 of the 12 groups in a 2×3×2 factorial design and remained blinded to the assigned intervention. The groups were defined based on personality type (thinking or feeling), message type (emotional, logical, or none), and repetition (none or once). Participants with different personality types received tailored and repeated messages. Finally, we used the self-reported completion rate to measure participants' adherence level to exercise plans. By analyzing users' usage patterns, we could verify, correct, and enhance the mHealth app design principles. RESULTS: In total, 160 users downloaded the app, and 89 active participants remained during the 2-month period. The results suggest a significant main effect of personality type and repetition and a significant interaction effect between personality type and repetition. The adherence rate of people with feeling personality types was 18.15% higher than that of people with thinking types. Emotional messages were more effective than logical messages in motivating exercise adherence. Although people received repeated messages, they were more likely to adhere to exercise plans. With repeated reminders, the adherence rates of people with thinking personality types were significantly improved by 27.34% (P<.001). CONCLUSIONS: This study contributes to the literature on mHealth apps. By incorporating a field experiment into the ADR process, we demonstrate the benefit of combining design science and field experiments. This study also contributes to the research on mHealth apps. The principles learned from this study can be applied to improve the effectiveness of mHealth apps. The app design can be considered a foundation for the development of more advanced apps for specific diseases, such as diabetes and asthma, in future research.

Perfil MBTI e a Tipologia dos Quatro Temperamentos: relações possíveis entre cargos de gestão e não gestão / MBTI Profile and the Four Temperament Typology: possible relationships between management and non-management positions / Perfil MBTI y la tipología de cuatro temperamentos: posibles relaciones entre puestos gerenciales y no gerenciales

A presente pesquisa objetivou avaliar a existência de um perfil de personalidade e de temperamento que possa ser associado aos ocupantes de cargos de gestão. Para isso foi realizada a análise documentária de 240.233 protocolos do MBTI, do banco de dados da empresa representante da ferramenta no Brasil, emitidos no período de 2007 a 2015. Como a base de dados para este estudo foi documental, não houve necessidade de submetê-lo ao Comitê de Ética, mas apenas da autorização expressa da empresa. Para a análise do temperamento, utilizou-se a teoria de David Keirsey por permitir sua associação com o MBTI. Da totalidade de protocolos analisados, 12,55% ocupavam algum cargo de gestão quando avaliados. Os resultados apontaram que as tipologias de personalidade ESTJ (Extrovertido, Sensorial, Racional, Julgador) e ISTJ (Introvertido, Sensorial, Racional, Julgador) e o temperamento Guardião são as que mais se destacam para todos os tipos de cargos. Conclui-se que não há uma tipologia ou um de temperamento que diferencie pessoas que ocupam cargos de gestão das que não ocupam, porém, há tipologias e temperamentos mais frequentemente observados para os profissionais de diversos cargos.

The present research aims to evaluate the existence of profiles from personality and temperament which can be associated with the occupants of management positions. In order to understand this relation, a documentary analysis has been made using 240,233 MBTI protocols, which represents the database of the company that owns the tool in Brazil from the period of 2007 to 2015. The theory of David Keirsey was used for this purpose and according to the characteristics of this study and the rules of the Ethics Committee, only the express authorization of the company was needed. The results indicate the ESTJ (Extroverted, Sensory, Rational, Judging) and ISTJ (Introverted, Sensory, Rational, Judging) personality typologies and the Guardian temperament are the ones that stand out the most for all types of positions and also 12.55% of the people analyzed in protocols occupied some management position. The conclusion presented there are no typology or temperament profiles that differentiate people who occupy management positions from those who do not. However, there are typologies and temperaments more frequently observed for professionals in different positions.

La presente investigación tuvo como objetivo evaluar la existencia de un perfil de personalidad y temperamento que puede asociarse a los ocupantes de los puestos de dirección. Para ello, se realizó un análisis documental de 240.233 protocolos MBTI de la base de datos de la empresa representante de la herramienta en Brasil, emitidos en el periodo de 2007 a 2015. Como la base de datos de este estudio era documental, no fue necesario presentarla al Comité de Ética, solamente de la autorización expresa de la empresa. Para el análisis del temperamento, se utilizó la teoría de David Keirsey porque permite su asociación con el MBTI. De todos los protocolos analizados, 12,55% ocupaba algún cargo directivo en el momento de la evaluación. Los resultados señalaron que las tipologías de personalidad ESTJ (Extrovertida, Sensorial, Racional, Juiciosa) e ISTJ (Introvertida, Sensorial, Racional, Juiciosa) y el temperamento Guardián son los más destacados para todos los tipos de trabajo. Se concluye que no existe una tipología o un temperamento que diferencie a las personas que ocupan cargos directivos de las que no lo hacen, sin embargo, hay tipologías y temperamentos que se observan con mayor frecuencia para profesionales de diversos cargos.

MBTI Personality Types of Korean Cabin Crew in Middle Eastern Airlines, and Their Associations with Cross-Cultural Adjustment Competency, Occupational Competency, Coping Competency, Mental Health, and Turnover Intention.

The purposes of this study were (1) to identify MBTI (Myers-Briggs Type Indicator) personality profiles of Korean cabin crew in Middle Eastern airlines, (2) to determine whether MBTI personality affects their cross-cultural adjustment competency, occupational competency, and coping competency, and (3) to analyze the impact of these variables on their mental health and turnover intention. Furthermore, we verified (4) the moderating effect of cabin crew's previous overseas experience on the relationship between cross-cultural adjustment competency and turnover intention. MBTI-Form M test and a survey questionnaire were distributed to 185 Korean cabin crew members in Middle Eastern airlines, and 172 valid datapoints were used for analysis. It was revealed that the cabin crew members showed significantly different levels of cross-cultural adjustment competency, occupational competency, and coping competency depending on their personality traits. Furthermore, those with higher cross-cultural adjustment competency and stress coping are more likely to have positive mental health, which also had an influence on lowering their turnover intention. Occupational competency had no significant association with mental health; however, it directly affects turnover intention. The findings will contribute not only to career plan guidelines for cabin crew aspirants, but also to airlines' recruitment strategies as well as human resources management in aviation industry.

On Pathology Laboratory Recruitment and Retention.

OBJECTIVES: The specific aims of the study are to analyze relationships between the personality traits of laboratory professionals and choice of profession and preferred work settings. METHODS: Data from practicing laboratory professionals were collected via a web-based survey tool to gather information about personality types, choice of profession, and work setting preferences among medical laboratory professionals. RESULTS: Results of the survey showed that INFJ (Introversion, Intuition, Feeling, Judging) is the most common medical laboratory personality type across the various laboratory work settings and that there are no significant differences between the practitioners' personality type and the choice of profession within pathology. The study revealed laboratorians from higher-volume laboratories were 1.2 times more likely to prefer Judging than lower-volume laboratories, and younger medical laboratory practitioners were 2.3 times more likely to gravitate toward Perceiving than their older counterparts. CONCLUSIONS: The results of this study shed light on how employers can build on the personality preferences of the laboratory workforce to improve personal job satisfaction and laboratory productivity, quality, and work culture. The research implications are useful for laboratory recruitment and retention.

Relationship Between Personality Types in MBTI and Dream Structure Variables.

This study aimed to explore relationships between personality type variables and dream structure variables. In the questionnaire experiment (N = 410), we investigated associations between different personality variables in the Myers-Briggs Type Indicator questionnaire (MBTI) and various aspects of dreams in the Mannheim Dream questionnaire (MADRE). The MBTI has four dimensions. In the Extroversion/Introversion (E/I) dimension, I types dreamt more of emotional intensity and passive emotions than E types. In addition, I types may become more distressed in nightmares than E types. E types more frequently shared their dreams with others. In the Sensation/Intuition (S/N) dimension, N types had a more positive attitude toward dreams and can get more novel ideas and help from their dreams than S types. In the dream diary experiment (N = 47), we investigated whether the S/N dimension may influence waking events' incorporation into dreams. External judges decoded paired waking events and dream reports. N types had more metaphorical incorporation than S types. More specifically, N types had more metaphorical expressions in their dreams than S types. This result may be due to the different characteristics between S types and N types. It may provide support for the dream continuity hypothesis.

Relationships Between Myers-Briggs Type Indicators and NAPLEX Performances.

Objective. To examine the relationships between pharmacy students' Myers-Briggs Type Indicators (MBTIs) and their first-attempt NAPLEX scores within an accelerated, dual campus curriculum. Methods. Data from the MBTIs and NAPLEX findings were retrieved from a single cohort of the Columbia, SC and Savannah, GA campuses of South University School of Pharmacy. A multiple linear regression technique was performed to assess the degree of variability in first-attempt NAPLEX scores that could be accounted for by MBTIs, campus of enrollment, and gender. Results. Of the 134 student data samples collected, 119 (86%) were included for study analysis. Campus of enrollment and MBTIs were predictive of first-attempt NAPLEX scores. Introversion personality types scored 9.5 points higher on the NAPLEX than extroversion types; feeling personality types scored 6.0 points higher than thinking types; students enrolled at the Savannah, GA campus scored 5.7 points higher than their Columbia, SC campus counterparts. Conclusion. Certain personality types were shown to have predictive value with regard to first-attempt NAPLEX score achievements. These results offer plausible insights into pharmacy student tendencies that can affect success on high-stakes standardized examinations. Additional research into sociological aspects of pharmacy students' composition may assist with optimizing performances on licensure examinations as prerequisites to proficient careers within the pharmacy profession.

Personality of Belgian physicians in a clinical leadership program.

BACKGROUND: Physician and non-physician leadership development programs aim to improve organizational performance. Although a significant, positive relation between physicians' leadership skills and patient outcomes, staff satisfaction and staff retention has been found, physicians are not formally trained in clinical leadership skills during their physician training. A lot of current healthcare leaders were chosen to take on leadership because of their productivity, published research, solid clinical skills, or because they were great educators, Heifetz RA. Leadership Without Easy Answers; 1994 although they often do not have the skills to build a team, resulting in dysfunctional teams and having to deal with conflicts and chaos. The first steps of a Clinical Leadership Program is to gain insight in one's personality, one's personal skills and one's leadership growth potential, because this gives information on one's natural leadership style. The aim of our research is to gain insight in the personality traits of healthcare professionals who are leading teams and to check (a) whether Belgian physicians with leadership ambition, share certain preferences, (b) whether physicians differ from other healthcare staff in terms of personality, (c) whether our sample of Belgian physicians differs from a population of physicians in the United States of America. METHODS: In-hospital physicians and non-physicians enrolled in a Clinical Leadership Program consented to participate. They explored their personal preferences across four dimensions, based on the Myers-Briggs Type Indicator (MBTI). Their most suitable MBTI profile was determined with a self-assessment and a complementary guidance of an MBTI-coach. Chi-squared tests and logistic regression were performed to check distributions across different MBTI-dimensions and to assess the relation with profession and location. RESULTS: Among participating physicians significantly more preferences for 'Thinking' then for 'Feeling' were found. Non-physicians were found to be significantly more 'Sensing' and 'Judging' compared with physicians. No significant differences were found between physicians from our (Belgian) and the USA dataset. CONCLUSION: Preferences of physicians proved to be different from those of non-physicians. 'ISTJ' is the most frequent personality profile both in Belgian and USA physicians.

Tipos Psicológicos y Estilos de Aprendizaje en Estudiantes de la Carrera de Odontología en la Universidad de La Frontera, Chile / Psychological Types and Learning Styles in Students of the Dental Graduation Program at Universidad de La Frontera, Chile

RESUMEN: El objetivo fue establecer los tipos psicológicos y estilos de aprendizaje de los estudiantes que cursaron de primer a sexto año de la Carrera de Odontología de la Universidad de La Frontera, Temuco, Chile. Se realizó un diseño cualitativo, correlacional, descriptivo y transeccional estableciendo la existencia de correlación entre los tipos psicológicos, sexo y nivel curricular aplicando dos instrumentos: tipos psicológicos de Myers y Briggs forma M versión español (MBTI, 2012) y el Inventario de Estilos de Aprendizaje de Kolb (IEA de Kolb). Se incluyeron 372 sujetos, 208 (56 %) del sexo femenino y 164 (44 %) del sexo masculino. Según el estilo de aprendizaje, los sujetos se caracterizaron mayoritariamente por ser divergentes (63 % de la muestra), seguido del grupo acomodador (26 % de la muestra) y finalmente le siguieron el grupo asimilador y convergente con un 8 % y 3 % respectivamente. Al avanzar de nivel curricular e ingresar en las asignaturas de clínicas odontológicas y tratar con pacientes, el tipo psicológico cambió gradualmente con predominancia de la dimensión extroversión e incremento de la dimensión Juicio a un ESTJ. El estilo de aprendizaje en los niveles cuarto, quinto y sexto fue más divergente para finalizar con un estiloacomodador en los estudiantes de sexto año. Se puede concluir que los tipos psicológicos y estilos de aprendizaje no fueron homogéneos en los distintos niveles curriculares.

ABSTRACT: The aim was to establish the psychological types and learning styles of the students between the first to sixth year of the Graduation Program in Dentistry at the University of La Frontera, Temuco, Chile. A qualitative, correlational, descriptive and transectional design was made to observe the existence of correlation between the psychological types, sex and curricular level applying two instruments: psychological types of Myers and Briggs form M Spanish version (MBTI, 2012) and the Inventory of Styles of Learning from Kolb (IEA of Kolb). Were included 372 subjects, 208 (56 %) female and 164 (44 %) male. According to the learning style, the subjects were characterized mainly by divergent (63 % of the sample), followed by the accommodating group (26 % of the sample) and finally followed by the assimilating and convergent group with 8 % and 3 % respectively. In more advance curricular level, mainly at dental clinics level and dealing with patients, the psychological type gradually changed with predominance of the extroversion dimension and increase of the Judgment dimension to an ESTJ. The learning style at the fourth, fifth and sixth levels was more divergent to end with an accommodating style in sixth grade students. It can be concluded that the psychological types and learning styles were not homogeneous at the different curricular levels.

The Prevalence of Pseudoscientific Ideas and Neuromyths Among Sports Coaches.

There has been an exponential growth in research examining the neurological basis of human cognition and learning. Little is known, however, about the extent to which sports coaches are aware of these advances. Consequently, the aim of the present study was to examine the prevalence of pseudoscientific ideas among British and Irish sports coaches. In total, 545 coaches from the United Kingdom and Ireland completed a measure that included questions about how evidence-based theories of the brain might enhance coaching and learning, how they were exposed to these different theories, and their awareness of neuromyths. Results revealed that the coaches believed that an enhanced understanding of the brain helped with their planning and delivery of sports sessions. Goal-setting was the most frequently used strategy. Interestingly, 41.6% of the coaches agreed with statements that promoted neuromyths. The most prevalent neuromyth was "individuals learn better when they receive information in their preferred learning style (e.g., auditory, visual, or kinesthetic)," which 62% of coaches believed. It is apparent that a relatively large percentage of coaches base aspects of their coaching practice on neuromyths and other pseudoscientific ideas. Strategies for addressing this situation are briefly discussed and include changing the content of coach education programs.

Personality Types and Application to Medical Education in Medical Students / 계명의대학술지

Myers-Briggs Type Indicator (MBTI) is a personality type test book, which is widely used in the field of personal counseling, team organization, school education and research. This study carried out MBTI of 361 medical students in the second grade of premedical course of Keimyung University School of Medicine from 2014 to 2018, and analyzed the data to use them for the students' education. The personality type was mostly distributed to ISTJ, ISTP, ESTP and ESTJ in order among 16 types. According to preference tendency, it was found out that the introverted type was extroverted, the recognition type was intuition type, the thinking type was emotional type, and the recognition type was more distributed than the judgment type. The psychological functions were ST, SF, NF, NT. MBTI type analysis of medical students shows that it is possible to organize members in group activities to improve their ability to understand themselves and understand others in class scenes. In addition, we expect to be able to design for improvement of stress management, conflict management, and communication ability. In the career counseling scene, in addition to the MBTI data analysis, it is expected that it will be possible to recommend a major suitable for the student personality type in parallel with other psychological tests. In addition, we expect to study the preferred field of study, satisfaction with the major in the future research by continuous data accumulation and analysis.

Assessment of personality type and medical specialty choice among medical students from Karachi; using Myers-Briggs Type Indicator (MBTI) tool.

OBJECTIVE: To assess personality type of medical students and associate it with their choice of medical specialty. METHODS: This cross-sectional study was conducted in February 2014 at one public and one private medical university of Karachi, and comprised medical students. A self- administered questionnaire based on Myers-Briggs type indicator was used to collect data which was analysed using SPSS 20. RESULTS: Of the 400 participants, there were 200(50%) each from public and private universities. Of all, 201(50.3%) students were found to be extroverted and 199(49.8%) were introverted personality types. Clinical fields were the main preference of students after their medical degree as selected by 317(79.2%) students; of the, Extroverted-Sensing-Feeling-Perceptive was the most common type identified in39(7.2%) students. Extroverted-Sensing-Feeling-Perceptive 11(2.8%), Extroverted-Sensing-Thinking-Judging 12(3%), Extroverted-Sensing-Feeling-Judging 5(1.3%), Introverted-Sensing-Feeling-Judging 6(1.5%), Introverted-Sensing-Thinking-Perceptive 7(1.8%) had preference for surgery, medicine, gynaecology, paediatrics and cardiology, respectively. CONCLUSIONS: Personality had significant impact on specialty and career choice.

Integration of ligand and structure based approaches for identification of novel MbtI inhibitors in Mycobacterium tuberculosis and molecular dynamics simulation studies.

Mycobacterium tuberculosis is an obligate pathogen of mammals and is responsible for more than two million deaths annually. The ability to acquire iron from the extracellular environment is a key determinant of pathogenicity in mycobacteria. M. tuberculosis acquires iron exclusively through the siderophores. Several lines of evidence suggest that siderophores have a critical role in bacterial growth and virulence. Hence, in the present study, we have used a combined ligand and structure-based drug design approach for identification of novel inhibitors against salicylate synthase MbtI, a unique and essential enzyme for the biosynthesis of siderophores in M. tuberculosis. We have generated the ligand based and structure based pharmacophores and validated exhaustively. From the validation results it was found that GH (Goodness of Hit) scores for the selected ligand based and structure based pharmacophore models were 0.89 and 0.97, respectively, which indicate that the quality of the pharmacophore models are acceptable as GH value is >0.7. The validated pharmacophores were used for screening the ZINC database. A total of 73 hits, obtained through various insilico screening techniques, were further enriched to 17 hits using docking studies. Molecular dynamics simulations were carried out to compare the binding mode and stability of complexes of MbtI bound with substrate, known inhibitors, and three top ranked hits. The results obtained in this study gave assurance about the identified hits as prospective inhibitors of MbtI.

The association between Myers-Briggs Type Indicator and Psychiatry as the specialty choice.

OBJECTIVE: The purpose of this pilot study is to examine the association between Myers-Briggs Type Indicator (MBTI) and prospective psychiatry residents. METHODS: Forty-six American medical schools were contacted and asked to participate in this study. Data were collected and an aggregated list was compiled that included the following information: date of MBTI administration, academic year, MBTI form/version, residency match information and student demographic information. The data includes 835 American medical students who completed the MBTI survey and matched into a residency training program in the United States. All analyses were performed using R 3.1.2. RESULTS: The probability of an introvert matching to a psychiatry residency is no different than that of an extravert (p= 0.30). The probability of an intuitive individual matching to a psychiatry residency is no different than that of a sensing type (p=0.20). The probability of a feeling type matching to a psychiatry residency is no different than that of a thinking type (p= 0.50). The probability of a perceiving type matching to a psychiatry residency is no different than that of a judging type (p= 0.60). CONCLUSIONS: Further analyses may elicit more accurate information regarding the personality profile of prospective psychiatry residents. The improvement in communication, team dynamics, mentor-mentee relationships and reduction in workplace conflicts are possible with the awareness of MBTI personality profiles.
