Targeted antitumour therapy – future perspectives
The advent of targeted therapy presents an unprecedented opportunity for advances in the treatment of cancer. A key challenge will be to translate the undoubted promise of targeted agents into tangible clinical benefits. Achieving this goal is likely to be dependent upon a number of factors. These include continued research to improve our understanding of the heterogeneity and complexity of the tumour microenvironment; refinement of clinical trial design to incorporate nontraditional end points such as the optimum biological dose and health-related quality of life; and the use of technological advancements in proteomics, genomics and biomarker development to better predict tumour types and patient subsets that may be particularly responsive to treatment, as well as enable a more accurate assessment of drug effect at the molecular level. In summary, the future success of targeted agents will require an integrated multidisciplinary approach involving all stakeholders
Treatment Protocols for Eating Disorders: Clinicians’ Attitudes, Concerns, Adherence and Difficulties Delivering Evidence-Based Psychological Interventions
There are several protocols in existence that guide clinicians in the implementation of effective, evidence-based psychological interventions for eating disorders. These have been made accessible in the form of treatment manuals. However, relatively few clinicians use those protocols, preferring to offer more eclectic or integrative approaches. Following a summary of the research that shows that these evidence-based approaches can be used successfully in routine clinical settings, this review considers why there is such poor uptake of these therapies in such settings. This review focuses on the role of service culture and on clinicians’ own attitudes, beliefs and emotions. Possible means of enhancing uptake are considered, but these cannot be considered to be ideal solutions at present
Platinum drugs in the treatment of non-small-cell lung cancer
The use of chemotherapy is considered standard therapy in patients with locally advanced non-small-cell lung cancer that cannot be treated with radiotherapy and in those with metastatic non-small-cell lung cancer and good performance status. This approach is also accepted in patients with earlier stage disease, when combined with radiotherapy in those with non-resectable locally advanced disease, or in the preoperative setting. Randomised clinical studies and meta-analyses of the literature have confirmed the beneficial survival effect of platinum-based chemotherapy. Cisplatin and carboplatin have been successfully used with other drugs in a wide variety of well-established two-drug combinations while three-drug combinations are still under investigation. Cisplatin and carboplatin use is limited by toxicity and inherent resistance. These considerations have prompted research into new platinum agents, such as the trinuclear platinum agent BBR3464, the platinum complex ZD0473 and oxaliplatin. These compounds could be developed in combination with agents such as paclitaxel, gemcitabine or vinorelbine in patients with advanced and/or refractory solid tumours
Transtornos alimentares e os espectros do humor e obsessivo-compulsivo Eating disorders and the mood and obsessive-compulsive spectrum
Revisamos os estudos clínicos e biológicos que sugerem que os transtornos alimentares (TA) são expressões fenotípicas de outros transtornos psiquiátricos e parte de espectros de psicopatologia, em especial dos espectros dos transtornos do humor e do transtorno obsessivo-compulsivo. A investigação da relação entre os TA e outros transtornos psiquiátricos através dos modelos espectrais pode proporcionar um melhor entendimento da fisiopatologia destas síndromes e a elaboração de tratamentos mais eficazes. Entretanto, o reconhecimento de que os TA possuem características peculiares e a adoção de uma postura crítica em relação a modelos que eliminam limites diagnósticos são também fundamentais para a evolução do conhecimento no campo.<br>We reviewed the clinical and biological studies which have suggested that eating disorders (ED) are phenotypical expressions of other psychiatric disorders and part of the spectra of other psychopathologies, specially the mood and obsessive-compulsive spectrum disorders. The study of the relationship between ED and other psychiatric disorders using the spectrum model of psychopathology may allow a better understanding of the pathophysiology of such syndromes and tailoring more effective treatments. However, the recognition that ED display particular characteristics and the adoption of a critical view with regard to models that eliminate diagnostic limits may also be important for the advancement in the area of eating behaviors
