[Academic Careers in Medicine: a Sex-Related Analysis of Career Goals]. / Akademische Karriere in der Medizin: eine geschlechterbezogene Analyse zu beruflichen Zielen.

AIM OF THE STUDY: For female and male physicians of the clinical-academic mid-level staff, working conditions as well as the attitude towards profession and career play a decisive role. For years, there has been an increasing proportion of women in medicine. Despite this increase, a significant sex incongruence is still evident, especially in academic medicine. The aim of this work was to analyze current opinions of female and male physicians on sex-related aspects for career. METHODS: By means of an online survey, medical mid-level staff from university and peripheral hospitals were asked about professional biographical as well as career-related topics and the data analyzed in terms of the sexes. RESULTS: Compared to their male counterparts, female physicians had lower career goals and mainly aimed to qualify as senior physicians. Women planned to have families and raise children earlier in their careers. Men were more likely to have their professional careers in mind during the same time period. Although only just under 47% of respondents considered an academic career to be worthwhile, 65% continued to rate the acquisition of an academic title highly. When evaluating equal treatment by superiors, female physicians tended to feel disadvantaged in their professional careers compared to male physicians. Thus, physicians rated the treatment by their respective superiors as characterized by the quality of the work (44% for both genders of superiors) or dependent on sympathy (female superiors 30%; male superiors 24%). Female physicians, however, saw a preference for male colleagues in 37% of male superiors. CONCLUSION: Despite a significantly larger proportion of women in medicine for decades, there is still an incongruence in sexes in favor of men in management positions. The professional and private goals of women and men differ significantly depending on their age decade. The academic career per se is increasingly losing importance, although the acquisition of academic degrees still seems to be desirable. Therefore, to improve the future of academic medicine, significant structural changes are needed to enable projectable career paths (e. g., tenure track, assistant professorship, young medical professionals model) for mid-level academic staff.

[Balancing Family and Career in Medicine: Greatly Desired but Given Little Consideration Results of the Study Arm VI of the KARiMED Study]. / Vereinbarkeit von Familie und Beruf in der Medizin: vom großen Wunsch und wenig Berücksichtigung.

AIM OF THE STUDY: Family life and professional practice are both highly important for young physicians. Accordingly, a good balancing of both areas of life is necessary. Despite political framework conditions and legal requirements that have been in place for years, implementation of measures to achieve this seems to be difficult, especially in medicine, and is associated with great reservations and problems on the part of those involved. METHODS: By means of an online survey, the medical mid-level staff from university and peripheral hospitals was questioned on topics related to family, children and professional biographical as well as career-relevant topics and subsequently analyzed on a gender-specific basis. RESULTS: Of the study participants, 65.1% were married and already had children or expressed a desire to have children (86.0%). Most were employed full-time (80.8%). The majority of part-time employees were female (87.4%). For 34.6%, there was a career break of 18.5±21.3 months, 87.8% of which were taken due to pregnancy or children. Female physicians generally took significantly more parental leave than male physicians (6-12 months: females 62.2%; males 22.4%; 12 months or more: females 25.2%; males 6.6%). Family planning received little support from superiors (21.2% much to very much support) and 45.6% reported having experienced problems with their return to work or career advancement. Almost 60% of the participants did not have any specific working time models in their own hospital for employees with children who need to be cared for. CONCLUSION: In order to implement a work-life balance for physicians, changes are first and foremost necessary on the part of the institutions. In addition, the respective superiors must rethink in order to enable a parallelization of these two areas of their employees' lives. However, young physicians must also rethink their view of this issue. Demanding changes in labor law while continuing traditional family constellations at home does not seem to do address this issue adequately.

[Change of perception of aged male attractiveness by conventional or male facelift: 3D simulation study of a new facelift concept for men]. / Veränderung der Wahrnehmung männlicher Attraktivität im Alter durch Standard- oder männliche Gesichtsstraffung: 3D-Simulationsstudie eines neuen Facelift-Konzeptes für Männer.

BACKGROUND: Facelift is now the fourth most common aesthetic procedure in men. Facial ageing is very different in men and women. Therefore, individual techniques are used since a uniform concept for the surgical facelift in men does not exist. This study aims to evaluate a gender-specific facelift concept especially developed for men. MATERIAL AND METHODS: Women and men (n = 10 each) were subjected to a three-dimensional face scan and a subsequent simulation of a V-shaped lift vector (standard lift) and a new facelift concept especially for men in a double T shape (male lift). In an online survey with 262 participants, the simulated as well as the unchanged images were presented and the attributes masculinity, femininity, attractiveness and youthfulness were queried. Statistical models were used to identify attributes of lifting as well as other factors and differences between the simulations. RESULTS: Facelift changes are generally associated with a significant improvement in the attributes of youthfulness and attractiveness compared with unchanged control faces. As expected, a male lift leads to masculinisation, while a standard lift leads to feminisation, regardless of the sex of the subjects. The male lift led to higher values for the attribute attractiveness in male subjects, as did the standard lift in female subjects. The standard lift developed for women is indeed more suitable for women and is associated with a significantly higher probability for the attribute youthfulness, whereas this is not the case in the newly introduced male lift concept. CONCLUSION: The new facelift concept for male patients is significantly associated with masculinity and attractiveness, while the standard lift suitable for women is associated with significantly higher evaluations of femininity and youthfulness. The results of the SIMALIFT study are the first evidence of the need for a more differentiated, gender-specific approach to facelifting.

Characterization of a PLLA-collagen I blend nanofiber scaffold with respect to growth and osteogenic differentiation of human mesenchymal stem cells.

We developed a nanofiber scaffold by blending PLLA with collagen I, suitable for bone regeneration. Among several PLLA-COLI ratios tested, cell growth was better enhanced when blends with a ratio of PLLA-COLI 4:1 were used. Here, growth as well as osteoblast differentiation of hMSC was improved when compared to PLLA nanofibers alone. Therefore, blending is a suitable tool to enhance PLLA nanofibers with respect to bone tissue engineering.

Influence of nanofibers on the growth and osteogenic differentiation of stem cells: a comparison of biological collagen nanofibers and synthetic PLLA fibers.

The aim of this study was to compare biological collagen I (ColI) and synthetic poly-(L: -lactide) (PLLA) nanofibers concerning their stability and ability to promote growth and osteogenic differentiation of human mesenchymal stem cells in vitro. Matrices were seeded with human stem cells and cultivated over a period of 28 days under growth and osteoinductive conditions and analyzed during the course. During this time the PLLA nanofibers remained stable while the presence of cells resulted in an attenuation of the ColI nanofiber mesh. Although there was a tendency for better growth and osteoprotegerin production of stem cells when cultured on collagen nanofibers, there was no significant difference compared to PLLA nanofibers or controls. The gene expression of alkaline phosphate, osteocalcin and collagen I diminished in the initial phase of cultivation independent of the polymer used. In the case of PLLA fibers, this gene expression normalized during the course of cultivation, whereas the presence of collagen nanofibers resulted in an increased gene expression of osteocalcin and collagen during the course of the experiment. Taken together the PLLA fibers were easier to produce, more stable and did not compromise growth and differentiation of stem cells over the course of experiment. On the other hand, collagen nanofibers supported the differentiation process to some extent. Nevertheless, the need for fixation as well as the missing stability during cell culture requires further work.
