Study Looks At HIV, Risk Behaviors Among Male Clients Of Sex Workers In Tijuana, Mexico
"A large percentage" of U.S. and Mexican men who regularly engage in sexual activity with sex workers in Tijuana, Mexico, do not use condoms and have a history of substance and alcohol use, according to a study published in the online journal AIDS, the Los Angeles Times" blog "L.A. Now" reports. The study, by researchers from Mexico and the University of California-San Diego, surveyed 400 men - both Mexico and U.S. residents - and found that half of the men had unprotected sex with a female sex worker within the last four months. Researchers noted that although Tijuana authorities require that sex workers be registered and tested regularly for HIV, "only about half of [sex workers] have registered or been tested," according to the blog. Thomas Patterson of the UC-San Diego"s department of psychiatry and the Veterans Affairs health center, said the findings indicate a need for an educational campaign targeting men who frequent sex workers (Perry, 7/11).

After Myocardial Infarction Fatigue Is Common
Half of all patients who undergo myocardial infarction are experiencing onerous fatigue four months after the infarction. The patients who are most fatigued are those who perceive the infarction as a sign of chronic illness, those who experience the illness as difficult to control, and those who believe that the illness has a large impact on their life. These are the conclusions of a thesis presented at the Sahlgrenska Academy.

Gefitinib Receives European Licence For The Treatment Of Lung Cancer For Patients With EGFR Activating Mutation Positive Tumours

AstraZeneca announced that it has received a licence by the European Medicines Agency (EMEA) for its oral targeted anti-cancer drug, gefitinib, for EGFR (epidermal growth factor receptor-tyrosine kinase) activating mutation positive patients with Non Small Cell Lung Cancer (NSCLC). NSCLC is the most common type of lung cancer and accounts for 80% of all lung cancer cases. [1] The licence means that for the first time, thousands [2] of patients undergoing first line treatment of NSCLC in the UK may benefit from a more effective, [3] oral alternative to doublet chemotherapy (UK standard of care) without many of the side effects associated with chemotherapy. [3] Gefitinib is licensed for use in adult patients with locally advanced or metastatic non-small cell lung cancer (NSCLC) with activating mutations of EGFR-TK (epidermal growth factor receptor-tyrosine kinase), in all lines of therapy. [4] Gefitinib is the only oral targeted therapy available for first line use, having demonstrated superior efficacy vs. doublet chemotherapy for patients with a specific genetic mutation of their tumours (EGFR activating mutation positive tumours) and is one of just a handful of anti cancer drugs already available to target only those patients most likely to benefit. EGFR mutation status of a patient"s tumour is a strong predictor of benefit with gefitinib. [3,5] When compared to standard chemotherapy, not only did significantly more patients with EGFR mutation positive tumours respond to treatment with gefitinib (71.2% v 47.3%, p=0.0001) but they also lived significantly longer without their cancer growing (progression free survival) (median PFS 9.5 months vs 6.3 months; HR 0.48, 95% CI 0.36 to 0.64, pAbout IPASS [3] IPASS was an open label, randomised, parallel-group study that assessed the efficacy, safety and tolerability of gefitinib versus carboplatin/paclitaxel as first-line treatment in a clinically selected population of patients from Asia. The study enrolled 1,217 patients in Asia with advanced NSCLC who had not received prior chemotherapy for advanced disease, whose tumours were of adenocarcinoma histology and who had either never smoked, or were former light smokers (ceased smoking at least 15 years ago and About INTEREST [6] The INTEREST (Iressa Non-small-cell lung cancer Trial Evaluating REsponse and Survival against Taxotere) study was a randomised, open-label, parallel-group, Phase III trial evaluating survival with gefitinib versus docetaxel in 1,466 patients with locally advanced or metastatic recurrent NSCLC who had previously received platinum-based chemotherapy. The primary endpoint of INTEREST was OS, with the objective of demonstrating that gefitinib was non-inferior to docetaxel chemotherapy. The INTEREST study met its primary objective, demonstrating equivalent overall survival (OS) and significant quality of life benefits for gefitinib compared to standard chemotherapy (docetaxel) in the pre-treated setting.[6] A retrospective analysis showed a significant improvement in PFS and ORR for gefitinib over docetaxel in patients with EGFR sensitising mutation positive tumours. [7] About gefitinib - Mode of Action: gefitinib is an EGFR-TKI (epidermal growth factor receptor-tyrosine kinase inhibitor), which targets and blocks the activity of the EGFR-TK, an enzyme that regulates intracellular signalling pathways implicated in cancer cell proliferation and survival. Growth factor signalling has been identified as a key driver of tumour growth and spread in a wide range of cancers - Gefitinib (250 mg) is a once-daily oral therapy. - Gefitinib is licensed in 36 countries for the treatment of patients with locally advanced or metastatic NSCLC who have previously received chemotherapy. About EGFR mutations - EGFR mutations are changes in the DNA sequence of the EGFR gene which codes for the EGFR protein, leading to the production of mutated EGFR, rather than wild-type (non-mutated) EGFR. Tumour cells with mutated EGFR seem to be drawn to signalling via the EGFR pathway. - The EGFR receptor has been shown to play an important role in NSCLC. Some patients will exhibit mutations within the gene of this receptor. - A mutation in the EGFR is a characteristic occurring in approximately 12.7% [8] of lung cancers in non-Asian patients. About lung cancer in the UK - Lung cancer is the second most commonly diagnosed cancer in the UK. Each year more than 38,000 people are diagnosed with lung cancer in the UK. [9] - There are several different types of lung cancer, NSCLC being the most common. 80% of lung cancer patients are diagnosed with NSCLC. [1] - The UK has one of the worst lung cancer survival rates in Europe, 8.6% survival at 5-years in England compared with a mean of 12.6% across Europe.
