RESUMEN

Palm oil is the most widely traded vegetable oil globally, with demand projected to increase substantially in the future. Almost all oil palm grows in areas that were once tropical moist forests, some of them quite recently. The conversion to date, and future expansion, threatens biodiversity and increases greenhouse gas emissions. Today, consumer pressure is pushing companies toward deforestation-free sources of palm oil. To guide interventions aimed at reducing tropical deforestation due to oil palm, we analysed recent expansions and modelled likely future ones. We assessed sample areas to find where oil palm plantations have recently replaced forests in 20 countries, using a combination of high-resolution imagery from Google Earth and Landsat. We then compared these trends to countrywide trends in FAO data for oil palm planted area. Finally, we assessed which forests have high agricultural suitability for future oil palm development, which we refer to as vulnerable forests, and identified critical areas for biodiversity that oil palm expansion threatens. Our analysis reveals regional trends in deforestation associated with oil palm agriculture. In Southeast Asia, 45% of sampled oil palm plantations came from areas that were forests in 1989. For South America, the percentage was 31%. By contrast, in Mesoamerica and Africa, we observed only 2% and 7% of oil palm plantations coming from areas that were forest in 1989. The largest areas of vulnerable forest are in Africa and South America. Vulnerable forests in all four regions of production contain globally high concentrations of mammal and bird species at risk of extinction. However, priority areas for biodiversity conservation differ based on taxa and criteria used. Government regulation and voluntary market interventions can help incentivize the expansion of oil palm plantations in ways that protect biodiversity-rich ecosystems.

RESUMEN

BACKGROUND: Capsular contracture remains one of the most commonly reported complications in aesthetic and reconstructive breast patients. Previous in vitro studies from the authors' laboratory have recommended a new triple antibiotic povidone-iodine irrigation (2000) and subsequently a triple antibiotic non-povidone-iodine-containing irrigant (2001) to optimize broad-spectrum coverage of various bacteria implicated in capsular contracture; however, the clinical efficacy of these in vitro studies remains unproven. The purpose of this study was to determine the clinical efficacy for the previously reported triple antibiotic breast irrigation. The cost-effectiveness of universal application of irrigation solutions in breast prosthesis surgery was analyzed as well. METHODS: Patients undergoing aesthetic and reconstructive breast implant procedures were treated with a standardized operative technique, including the use of triple antibiotic breast irrigation by a single surgeon. Capsular contracture was assessed using a simplified Baker scale and graded by two independent caregivers to maximize objectivity and consistency. Additional complications were also recorded, including reoperation. Patient charges for antibiotic irrigation and reoperation for contracture were determined and compared. RESULTS: A total of 335 patients operated on since 1997 were evaluated prospectively. They ranged in age from 18 to 86 years, and the mean follow-up was 14 months (range, 6 to 75 months). The rate of grade III/IV capsular contracture in the study groups was 1.8 percent for patients undergoing primary breast augmentation. Patients undergoing augmentation-mastopexy had a grade III/IV contracture rate of 0 percent. Breast reconstruction patients had a 9.5 percent rate of grade III/IV contracture. CONCLUSIONS: Triple antibiotic breast irrigation is clinically associated with a low incidence of capsular contracture compared with other published reports, and its clinical efficacy supports previously published in vitro studies. Application of triple antibiotic irrigation is recommended for all aesthetic and reconstructive breast procedures and is cost effective.

RESUMEN

The majority of existing human papillomavirus (HPV) genotyping assays are based on multiplex PCR using consensus or degenerate primers. We developed a Templex HPV assay that simultaneously detects and identifies 25 common HPV genotypes in a single-tube reaction using type-specific primers for the HPV-specific E6 and E7 genes. The analytical sensitivities of the Templex assay for HPV type 16 (HPV-16), -18, and -56 were 20, 100, and 20 copies per reaction mixture, respectively. The Templex assay provides semiquantitative information on each type when multiple HPV types coexist in one reaction. We tested 109 clinical cervical specimens previously evaluated with the Digene HC2 high-risk HPV DNA test and found 95.4% concordance between the assay results. The Templex assay provided type-specific results and found multiple types in 29.2% (14 of 48) of high-risk HPV-positive samples. The entire Templex procedure, including DNA extraction, can be completed within 5 hours, providing a rapid and reliable diagnostic tool for HPV detection and typing that is amenable to automation.
