The evolving profile, role and relevance of the medical director in a pharmaceutical company

Over the last years, operations in Pharmaceutical Companies have become more complex, trying to adapt to new demands of the market environment. Overall, the observed change of paradigm requires adapting, mainly by the setting of new priorities, diversification of investments, cost containment strategies, exploring new markets and developping new sets of skills. In this context, new functions have been created, the relevance of some has diminished, and the importance of others has arisen. Amongst these, the medical structure within a Pharmaceutical Company, increased to meet demands, with companies adopting different models to respond to these needs, and becoming a pillar to the business. Assuming the leading role within a medical department, the medical director function often lies in the shadow. It is a key function within Pharma Industry, either on a country or on a Global basis. It has evolved and changed in the past years to meet the constant demands of a changing environment. The Medical Director is a highly skilled and differeniated professional who provides medical and scientific governance within a Pharmaceutical company, since early stages of drug development and up to loss of exclusivity, not only but also by leading a team of other physicians, pharmacists or life scientists whose functions comprise specificities that the medical director needs to understand, provide input to, oversee and lead. As the organization of Pharmaceutical Companies tends to be different, in accordance to values, culture, markets and strategies, the scope of activities of a Medical Director can be broader or may be limited, depending on size of the organization and governance model, but they must fulfil a large set of requirements in order to leverage impact on internal and internal customers. Key technical competencies for medical directors such as an MD degree, a strong clinical foundation, knowledge of drug development, project and team management experience and written and verbal skills are relatively easy to define, but underlying behavioural competencies are more difficult to ascertain, and these are more often the true predictors of success in the role. Beyond seamless proficiency in technical skills, at this level interpersonal skills become far more important, as they are the driver and the distinctive factor between a good and an excelent medical director. And this has impact in the business and in the people doing it.

FTIR, a potential tool to dementia diagnosis trough analysis of plasma

Nowadays it is still difficult to perform an early and accurate diagnosis of dementia, therefore many research focus on the finding of new dementia biomarkers that can aid in that purpose. So scientists try to find a noninvasive, rapid, and relatively inexpensive procedures for early diagnosis purpose. Several studies demonstrated that the utilization of spectroscopic techniques, such as Fourier Transform Infrared Spectroscopy (FTIR) and Raman spectroscopy could be an useful and accurate procedure to diagnose dementia. As several biochemical mechanisms related to neurodegeneration and dementia can lead to changes in plasma components and others peripheral body fluids, blood-based samples and spectroscopic analyses can be used as a more simple and less invasive technique. This work is intended to confirm some of the hypotheses of previous studies in which FTIR was used in the study of plasma samples of possible patient with AD and respective controls and verify the reproducibility of this spectroscopic technique in the analysis of such samples. Through the spectroscopic analysis combined with multivariate analysis it is possible to discriminate controls and demented samples and identify key spectroscopic differences between these two groups of samples which allows the identification of metabolites altered in this disease. It can be concluded that there are three spectral regions, 3500-2700 cm -1, 1800-1400 cm-1 and 1200-900 cm-1 where it can be extracted relevant spectroscopic information. In the first region, the main conclusion that is possible to take is that there is an unbalance between the content of saturated and unsaturated lipids. In the 1800-1400 cm-1 region it is possible to see the presence of protein aggregates and the change in protein conformation for highly stable parallel β-sheet. The last region showed the presence of products of lipid peroxidation related to impairment of membranes, and nucleic acids oxidative damage. FTIR technique and the information gathered in this work can be used in the construction of classification models that may be used for the diagnosis of cognitive dysfunction.
