RESUMO
Peatlands are wetland ecosystems with great significance as natural habitats and as major global carbon stores. They have been subject to widespread exploitation and degradation with resulting losses in characteristic biota and ecosystem functions such as climate regulation. More recently, large-scale programmes have been established to restore peatland ecosystems and the various services they provide to society. Despite significant progress in peatland science and restoration practice, we lack a process-based understanding of how soil microbiota influence peatland functioning and mediate the resilience and recovery of ecosystem services, to perturbations associated with land use and climate change. We argue that there is a need to: in the short-term, characterise peatland microbial communities across a range of spatial and temporal scales and develop an improved understanding of the links between peatland habitat, ecological functions and microbial processes; in the medium term, define what a successfully restored 'target' peatland microbiome looks like for key carbon cycle related ecosystem services and develop microbial-based monitoring tools for assessing restoration needs; and in the longer term, to use this knowledge to influence restoration practices and assess progress on the trajectory towards 'intact' peatland status. Rapid advances in genetic characterisation of the structure and functions of microbial communities offer the potential for transformative progress in these areas, but the scale and speed of methodological and conceptual advances in studying ecosystem functions is a challenge for peatland scientists. Advances in this area require multidisciplinary collaborations between peatland scientists, data scientists and microbiologists and ultimately, collaboration with the modelling community. Developing a process-based understanding of the resilience and recovery of peatlands to perturbations, such as climate extremes, fires, and drainage, will be key to meeting climate targets and delivering ecosystem services cost effectively.

The use of telehealth as a service delivery method for early intervention (EI) is in its infancy and few studies have examined its use within the context of a statewide program. The focus of this report was to determine the factors that influence providers' utilization of telehealth in Colorado's Part C Early Intervention program (EI Colorado). This report presents information that was gathered through surveys sent to Part C program administrators, service coordinators, providers, and caregivers. Surveys were used to understand perceptions of telehealth, actual experiences with telehealth, and perceived benefits and challenges using this service delivery method. Follow-up focus groups were conducted with program administrators and family members to gather more nuanced information. Participants identified several benefits associated with telehealth including its flexibility, access to providers, and more family engagement. The primary barriers included access to high speed internet and the opinion that telehealth was not as effective as in-person treatment. The results in the report served to identify next steps in the implementation of telehealth in Colorado's Part C EI program.
RESUMO
Understandably, given the fast pace of biodiversity loss, there is much interest in using Earth observation technology to track biodiversity, ecosystem functions and ecosystem services. However, because most biodiversity is invisible to Earth observation, indicators based on Earth observation could be misleading and reduce the effectiveness of nature conservation and even unintentionally decrease conservation effort. We describe an approach that combines automated recording devices, high-throughput DNA sequencing and modern ecological modelling to extract much more of the information available in Earth observation data. This approach is achievable now, offering efficient and near-real-time monitoring of management impacts on biodiversity and its functions and services.
RESUMO
Over recent decades, Land Use and Cover Change (LUCC) trends in many regions of Europe have reconfigured the landscape structures around many urban areas. In these areas, the proximity to landscape elements with high forest fuels has increased the fire risk to people and property. These Wildland-Urban Interface areas (WUI) can be defined as landscapes where anthropogenic urban land use and forest fuel mass come into contact. Mapping their extent is needed to prioritize fire risk control and inform local forest fire risk management strategies. This study proposes a method to map the extent and spatial patterns of the European WUI areas at continental scale. Using the European map of WUI areas, the hypothesis is tested that the distance from the nearest WUI area is related to the forest fire probability. Statistical relationships between the distance from the nearest WUI area, and large forest fire incidents from satellite remote sensing were subsequently modelled by logistic regression analysis. The first European scale map of the WUI extent and locations is presented. Country-specific positive and negative relationships of large fires and the proximity to the nearest WUI area are found. A regional-scale analysis shows a strong influence of the WUI zones on large fires in parts of the Mediterranean regions. Results indicate that the probability of large burned surfaces increases with diminishing WUI distance in touristic regions like Sardinia, Provence-Alpes-Côte d'Azur, or in regions with a strong peri-urban component as Catalunya, Comunidad de Madrid, Comunidad Valenciana. For the above regions, probability curves of large burned surfaces show statistical relationships (ROC value > 0.5) inside a 5000 m buffer of the nearest WUI. Wise land management can provide a valuable ecosystem service of fire risk reduction that is currently not explicitly included in ecosystem service valuations. The results re-emphasise the importance of including this ecosystem service in landscape valuations to account for the significant landscape function of reducing the risk of catastrophic large fires.

The use of telehealth has been discussed nationally as an option to address provider shortages for children, birth through two, enrolled in Part C of the Individuals with Disabilities Education Act (IDEA) Early Intervention (EI) programs. Telehealth is an evidence-based service delivery model which can be used to remove barriers in providing EI services to children and their families. In 2016, Colorado's Part C Early Intervention (EI) program began allowing the use of telehealth as an option for providers to conduct sessions with children and their caregivers. This article outlines the process taken to develop the necessary requirements and supports for telehealth to be incorporated into EI current practice.
RESUMO
This study explored the impact of prior personal experience with grief on self-reported personal and professional development of graduate students in nursing, social work, counseling, pastoral care, and genetic counseling involved as cofacilitators in bereavement support groups, and of medical students observing interdisciplinary inpatient palliative care. Personal experience with death of a family member or close friend was reported in 80% of the 35 participating students. Findings suggest that grief and the students' construction of the meaning of their loss can mediate the students' developing sense of self as a professional helper. Active engagement with suffering persons, the opportunity for self-disclosure and reflection, and teacher-facilitator provision of emotional guidance and modeling contributed positively to learning.

OBJECTIVE: The purpose of this research was to characterize the spatiotemporal expression of P450c17 in the human fetal ovary. DESIGN: P450c17 protein was visualized in sections of control and anencephalic ovaries using immunohistochemistry. SUBJECTS: Subjects included control (nonanencephalic) and anencephalic human fetal ovaries during the second and third trimesters. RESULTS: In second-trimester control ovaries, P450c17 was highly expressed in primary interstitial cells (PIC) located between the ovigerous cords near the cortical-medullary border where meiosis and primordial follicle formation were occurring. Morphometric analysis revealed a progressive decrease in the number of PIC during the second trimester, suggesting that PIC might have a finite lifetime. Between 25 and 32 wk, relatively few cells stained positive for P450c17; however, after 33 wk, P450c17 was strongly expressed in theca interstitial cells (TIC) bordering developing follicles. Surprisingly, the TIC appeared remarkably early during folliculogenesis, e.g. as early as the primary-to-secondary transition, and exhibited notable hyperplasia throughout preantral and early antral follicle growth. Owing to large numbers of developing preantral follicles, the third trimester was characterized by an increased abundance of P450c17-positive TIC. During this time period, P450c17 was strongly expressed in the hilus interstitial cells juxtaposed to the rete ovarii. Studies of ovaries of anencephalic fetuses revealed a similar spatiotemporal pattern of P450c17 expression in the PIC, TIC, and hilus interstitial cells, consistent with the possibility that pituitary hormones may not be involved in P450c17 expression in fetal ovaries. CONCLUSION: We identified three different classes of P450c17-expressing interstitial cells in the human fetal ovary, each having a different spatiotemporal pattern of P450c17 expression and, presumably, a different set of physiological functions.

This study is part of a larger study comparing prescribing practices of psychiatrists and advanced practice psychiatric nurses (APRNs) using the following three groups of patients: patients treated by psychiatrists, those treated by APRNs, and those treated by both APRNs and psychiatrists at different times in 1 year. Demographics for 5507 patients were examined. A subsample of APRNs and psychiatrists prescribed similar total numbers of medications. Psychiatrists prescribed more types of antidepressant medications other than the SSRI antidepressants, and they prescribed more than twice the number of benzodiazepines. APRNs prescribed more SSRIs and spent more time with clients during medication visits.

BACKGROUND: Lack of communication from healthcare providers contributes to the anxiety and distress reported by patients' families after a patient's death in the intensive care unit. OBJECTIVE: To obtain a detailed picture of the experiences offamily members during the hospitalization and death of a loved one in the intensive care unit. METHODS: A qualitative study with 4 focus groups was used. All eligible family members from 8 intensive care units were contacted by telephone; 8 members agreed to participate. RESULTS: The experiences of the family members resembled a vortex: a downward spiral of prognoses, difficult decisions, feelings of inadequacy, and eventual loss despite the members' best efforts, and perhaps no good-byes. Communication, or its lack, was a consistent theme. The participants relied on nurses to keep informed about the patients' condition and reactions. Although some participants were satisfied with this information, they wishedfor more detailed explanations ofprocedures and consequences. Those family members who thought that the best possible outcome had been achieved had had a physician available to them, options for treatment presented and discussed, andfamily decisions honored. CONCLUSIONS: Uncertainty about the prognosis of the patient, decisions that families make before a terminal condition, what to expect during dying, and the extent of a patient s suffering pervade families' end-of-life experiences in the intensive care unit. Families' information about the patient is often lacking or inadequate. The best antidote for families' uncertainty is effective communication.
