RESUMEN
Invasive Scedosporium spp. and Lomentospora prolificans infections are an emerging threat in immunocompromised and occasionally in healthy hosts. Scedosporium spp. is intrinsically resistant to most, L. prolificans to all the antifungal drugs currently approved, raising concerns about appropriate treatment decisions. High mortality rates of up to 90% underline the need for comprehensive diagnostic workup and even more for new, effective antifungal drugs to improve patient outcome. For a comprehensive analysis, we identified cases of severe Scedosporium spp. and L. prolificans infections from the literature diagnosed in 2000 or later and the FungiScope® registry. For 208 Scedosporium spp. infections solid organ transplantation (n = 58, 27.9%) and for 56 L. prolificans infection underlying malignancy (n = 28, 50.0%) were the most prevalent risk factors. L. prolificans infections frequently presented as fungemia (n = 26, 46.4% versus n = 12, 5.8% for Scedosporium spp.). Malignancy, fungemia, CNS and lung involvement predicted worse outcome for scedosporiosis and lomentosporiosis. Patients treated with voriconazole had a better overall outcome in both groups compared to treatment with amphotericin B formulations. This review discusses the epidemiology, prognostic factors, pathogen susceptibility to approved and investigational antifungals, and treatment strategies of severe infections caused by Scedosporium spp. and L. prolificans.

AIM: Identified Palliative Care Beds (Lits Identifiés Soins Palliatifs - LISPs) is a French specificity. Primarily created to integrate palliative care culture into conventional hospital units, the relevance of this measure became a controversial issue. Nowadays, hospital teams continue to frequently encounter complex situations regarding medical care for palliative patients. To the best of our knowledge, there is only one study, a quantitative one, bridging the gap about that subject. It showed failure in practicing palliative care work around LISP. Our study is based on a qualitative method that complements the quantitative study. It aimed to describe difficulties that limit palliative care practices in managing adult patients in LISP. METHOD: This qualitative exploratory survey was conducted with a sample of health service professionals (n=20), from senior physicians to caregivers. Each semi-structured interview included open questions regarding their experiences, feelings and difficulties with palliative care practices on LISP. It also included closed questions concerning interviewee's demographics and career course. The data for this research were submitted to a two-stage analysis: first, a global review of each interview was performed to identify trends. Then, a detailed breakdown, question by question, was implemented. RESULTS: From a quantitative perspective, the interviews revealed 305 difficulties, indicating the gaps and barriers limiting the implementation of a palliative approach in these services. From a qualitative perspective, five topics raised our attention by their recurrence in discourses: (1) partial knowledge about palliative care definition and legislation mostly due to a lack of training; (2) need for time; (3) need for human resources; (4) need for communication; (5) hard time in transitioning from curative to palliative care. PERSPECTIVE: This survey gives the opportunity to understand health service professionals' difficulties in practicing palliative care in conventional medical services. It raises the central issue of the pricing reform on the health institutes activity. It also provides angles of inquiry to improve LISP effectiveness. This qualitative and descriptive study was designed to explore difficulties in practicing palliative care around LISP. Nevertheless, according to the size of the sample, results will need to be confirmed by a more extensive qualitative survey.
