Desenvolvimento de wearable para transtornos de ansiedade e pânico

Devido ao número crescente de indivíduos diagnosticados com transtornos de Ansiedade e Pânico e, também, da exorbitante quantidade de novas informações expostas a cada segundo, a sociedade presente necessita de medidas urgentes para reverter o quadro atual antes que seja tarde demais para a saúde mental de um todo. Desta forma, foi desenvolvido neste projeto um wearable que diminui os sintomas de uma crise de ansiedade e pânico do usuário, conectado à um aplicativo que também monitora seus sinais vitais e serve de apoio ao produto. Assim, a qualidade de vida do usuário irá melhorar e crises serão evitadas no futuro (sempre acompanhado de terapia com profissionais da área de saúde mental)

The NAME trial:a direct comparison of classical oral Navelbine versus metronomic Navelbine in metastatic breast cancer

Chemotherapy for metastatic breast cancer (MBC) is in general given in cycles of maximum tolerated doses to potentially maximize the therapeutic outcome. However, when compared with targeted therapies for MBC, conventional and dose intensified chemotherapy has caused only modest survival benefits during the recent decades, often compromising the quality of life considerably. Navelbine is an antineoplastic agent that has shown efficacy in the treatment of a variety of cancer types, including breast cancer. Early clinical trials involving both breast cancer and lung cancer patients suggest that metronomic dosing of Navelbine might be at least as effective as classical administration (once weekly, etc.). The NAME trial compares these two strategies of Navelbine administration in MBC patients

Serum HER-2 concentrations for monitoring women with breast cancer in a routine oncology setting

Background: The purpose of this study was to determine the positive predictive value (PPV) of positive serum human epidermal growth factor receptor-2 (HER-2) for monitoring women with breast cancer following diagnosis and treatment in a routine clinical setting. Methods: Serum HER-2 was measured in 1348 patients with breast cancer: 837 during routine oncology clinic visits and 511 following new diagnosis. All patients with positive serum HER-2, 1/5 of negative patients from the oncology clinic, and all the newly diagnosed were followed; a total of 862 patients. Serum HER-2 was measured using the Bayer ADVIA Centaur assay. Tissue HER-2 was determined using immunohistochemistry (IHC) and fluorescence in situ hybridization (FISH). IHC +3 or IHC +2 and FISH>2.0 were positive. Patients were considered to have positive serum HER-2 when at least two values were >15 ng/mL. Recurrence, progression and regression were diagnosed according to usual clinical practice. Serum HER-2 concentrations did not contribute to diagnostic decision-making or selection of treatment. Results: From January 2004 to January 2009, 149 patients were found to have positive serum HER-2. Of these, 35 were tissue HER-2 positive at surgery, 69 tissue-negative and 45 were not determined. Fifty-five of 149 that were serum HER-2 positive (37%, 95% CI: 29–45) had metastases. Among the 35 tissue-positive patients, 25 had recurrence in the form of metastases and there was good correlation between recurrence/progression and increase in serum HER-2 (p<0.0003). There was also a high correlation between effect of treatment and decline in serum HER-2 (p<0.0003). Of the 69 tissue-negative patients, 29 had recurrence in the form of metastases, and there was good correlation with serum HER-2 levels (p<0.000004). In this routine application of serum HER-2, the PPV for metastases recurrence detection in both tissue-positive and tissue-negative was 54 of 104 (52%, 95% CI: 42%–62%), in tissue-positive 25 of 35 (71%, 95% CI: 54%–85%), in tissue-negative 29 of 69 (42%, 95% CI: 30%–54%). The lead time of increases in serum HER-2 before recurrence could be determined in ten tissue-positive patients was 3–24 months (mean 11.3 months), when compared to standard clinical imaging methods. Conclusions: Serum HER-2 is a useful marker for the detection of recurrence of breast cancer and for monitoring the effect of treatment, especially in tissue HER-2 positive patients.
