Informing research priorities for immature sea turtles through expert elicitation

This is the final version. Available from Inter Research via the DOI in this record. Although sea turtles have received substantial focus worldwide, research on the immature life stages is still relatively limited. The latter is of particular importance, given that a large proportion of sea turtle populations comprises immature individuals. We set out to identify knowledge gaps and identify the main barriers hindering research in this field. We analyzed the perceptions of sea turtle experts through an online survey which gathered their opinions on the current state of affairs on immature sea turtle research, including species and regions in need of further study, priority research questions, and barriers that have interfered with the advancement of research. Our gap analysis indicates that studies on immature leatherback Dermochelys coriacea and hawksbill Eretmochelys imbricata turtles are lacking, as are studies on all species based in the Indian, South Pacific, and South Atlantic Oceans. Experts also perceived that studies in population ecology, namely on survivorship and demography, and habitat use/behavior, are needed to advance the state of knowledge on immature sea turtles. Our survey findings indicate the need for more interdisciplinary research, collaborative efforts (e.g. data-sharing, joint field activities), and improved communication among researchers, funding bodies, stakeholders, and decision-makers

Global Health Perspective in Sarcomas and Other Rare Cancers

Sarcomas, rare and heterogenous malignancies that comprise less than 1% of all cancers, have poor outcomes in the metastatic and refractory setting. Their management requires a multidisciplinary approach that consists of medical and surgical oncologists, radiation oncologists, and pathologists as well as ancillary support. In addition to systemic treatments, most patients will require surgical resection and radiation therapy, which mandates the use of the latest technologies and specialized expertise. Management guidelines have been developed in high-income countries, but their applicability in low-income countries, where resources may be limited, remains a challenge. In this article, we propose the best possible evidence-based practices specifically for income-constrained settings to overcome this challenge. In addition, we review the different methods that can be used in low-income countries to access new and expensive treatments, which often times carry prohibitive costs for these areas

Extremity Soft Tissue Sarcoma in Adults

When treating soft tissue sarcomas (STSs) of the extremities, the major therapeutic goals are survival, local tumor control, optimal function, and minimal morbidity. Surgical resection of the primary tumor is the essential component of treatment for virtually all patients. A wide surgical margin is necessary for local tumor control when surgery is used without radiation, i.e., the cut should traverse normal tissue outside the reactive tumor zone. This is because sarcomas tend to infiltrate normal tissue adjacent to the evident lesion. Thus, removal of the gross lesion by a simple excision alone (only a narrow margin) is followed by relatively high rates of local recurrence. Radical resections are associated with a reduction in the local recurrence rate, but they may compromise limb function. The combination of function-sparing surgery and radiation achieves better rates of local control than either treatment alone, for nearly all patients with STSs, although combined treatment can be associated with acute wound complications in some patients and late normal tissue complications in others. Because both surgical and radiation techniques are both critically important for optimizing local control of tumor and functional outcome, it is important to manage these patients in dedicated multispecialty clinics comprised of physicians with expertise in sarcomas, including orthopedic and general oncology surgeons, radiation oncologists, medical oncologists, sarcoma pathologists, and bone and soft tissue diagnostic radiologists. Radiation therapy can be given by external beam radiation (EBRT) or brachytherapy or combination thereof. EBRT can be given either pre-operatively or post-operatively
