Perception, knowledge and attitudes towards environmental issues and management among coastal users of the most important beach destination in Argentina

This study was designed to address coastal users' perception in the largest seaside summer resort in Argentina regarding beach physical features and quality assessments, including issues related to the impacts of marine pollution, particularly litter on local beaches. We also explore the dependence of answers in certain traits of coastal users' profile (i.e. users’ age, gender and residence status). There was a strong relationship of predictor variables pertaining to the respondents' profile on the users' perception about environmental related aspects as well as beach quality assessment related topics. Virtually all respondents stated acknowledging that pollution by beach litter harms marine aquatic life, with plastics being the most commonly identified litter item. Interestingly, though, the users' perception about topics related to beach litter was not affected by residence status, gender or age. Addressing the issues linked to responsible and sustainable use of the environment in coastal localities in northern Argentina like Mar del Plata should include the participation of beachgoers, as these can help to improve beach management plans and assist managers and stakeholders identifying key issues in environmental policy to be implemented by coastal jurisdictions.Fil: Seco Pon, Juan Pablo.

PET-adapted therapy after three cycles of ABVD for all stages of Hodgkin lymphoma: results of the GATLA LH-05 trial

The role of Ann Arbor staging in determining treatment intensity after achieving a negative positron emission tomography (PET) has not been established in classical Hodgkin lymphoma (cHL). Patients with stage I–IV cHL, received three cycles of ABVD (doxorubicin, bleomycin, vinblastine, dacarbazine) and an interim PET scan (PET3). PET3-negative patients received no further therapy. PET3-positive patients received three additional cycles of ABVD plus involved-field radiation therapy or salvage chemotherapy, if refractory to ABVD, and were re-evaluated by PET scan (PET6). Study endpoints were 3-year progression-free survival (PFS) and overall survival (OS) rates. Two hundred and thirty-nine patients with early-stage and 138 with advanced-stage were evaluable. Overall, 260 patients (70%) were PET3-negative and had higher 3-year PFS (90% vs. 65%; P < 0 0001) and OS (98% vs. 92%; P = 0 007) rates than PET3-positive patients. All PET3-negative patients, regardless of disease stage at diagnosis, achieved similarly good PFS (90–91%; P = 0 76) and OS (97–99%). The only independent prognostic factor for PFS was PET3-negativity (Hazard ratio 3 8; 95% confidence interval 2 4–6 3; P < 0 0001). This study suggests that cHL patients who achieve a negative PET3 following ABVD have an excellent outcome, regardless of stage at diagnosis. An appropriately powered, phase III trial will be necessary to confirm these findings.Fil: Pavlovsky, Astrid. Fundación Para Combatir la Leucemia; Argentina.
