RESUMO

Over one-fourth of the world's land area is dedicated to agriculture, and these lands provide important ecosystem services (ES). Trees are a key component of agricultural ecosystems' ability to provide ES, especially in tropical regions. Agricultural landowners' evaluation of the ES provided by trees influences management decisions, impacting tree cover at large scales. Using a case study approach, we conducted semi-structured interviews with four types of agricultural landowners in southern Costa Rica to better understand how they value ES provided by trees. We used a socio-cultural valuation method, which revealed that landowners highly valued regulating and provisioning ES provided by trees and that the number and type of ES identified was influenced by the principle economic activity. Those farmers with larger amounts of forests on their properties more often identified cultural ES. The socio-cultural valuation methods revealed that respondents valued trees as wildlife habitat, coupling supporting and cultural services with both material (e.g., tourism) and non-material benefits (e.g., beauty). Few farmers in the study benefited from payment for ecosystem services programs, but the high value farmers placed on trees indicates there are other opportunities to increase tree cover on farms, such as promotion of live fencing and expanded riparian corridors. Results from this work can help improve conservation outcomes by shifting the focus of ecosystem service valuation to the needs and concerns of small-scale farmers in the development of outreach programs, management plans, and policies aimed at increasing tree cover on private lands in agricultural landscapes.

RESUMO

Given the important role that animal vocalizations play in mate attraction and resource defence, acoustic signals are expected to play a significant role in speciation. Most studies, however, have focused on the acoustic traits of male animals living in the temperate zone. In contrast to temperate environments, in the tropics, it is commonplace for both sexes to produce complex acoustic signals. Therefore, tropical birds offer the opportunity to compare the sexes and provide a more comprehensive understanding of the evolution of animal signals. In this study, we quantified patterns of acoustic variation in Rufous-and-white Wrens (Thryophilus rufalbus) from five populations in Central America. We quantified similarities and differences between male and female songs by comparing the role that acoustic adaptation, cultural isolation and neutral genetic divergence have played in shaping acoustic divergence. We found that males and females showed considerable acoustic variation across populations, although females exhibited greater population divergence than males. Redundancy analysis and partial-redundancy analysis revealed significant relationships between acoustic variation and ecological variables, genetic distance, and geographic distance. Both ambient background noise and geographic distance explained a high proportion of variance for both males and females, suggesting that both acoustic adaptation and cultural isolation influence song. Overall, our results indicate that parallel evolutionary forces act on male and female acoustic signals and highlight the important role that cultural drift and selection play in the evolution of both male and female songs.

RESUMO

Hemophagocytic lymphohistiocytosis (HLH) is characterized by dysregulated immune activation.  Primary HLH involves hereditary deficits in cytotoxic lymphocytes while secondary HLH is triggered by extrinsic factors. The HLH-2004 criteria are widely used for clinical diagnosis, yet their specificity for HLH or their ability to differentiate primary from secondary disease is unclear, potentially leading to inappropriate treatment. We describe several cases where fulfillment of HLH-2004 criteria obscured the diagnoses of underlying malignancies and delayed curative management. These issues are remedied without waiting for genetic testing results through an alternative diagnostic approach using flow cytometry-based immunologic assays and a thorough investigation for malignancy.

RESUMO

Hosts of avian brood parasites often use visual cues to reject foreign eggs, and several lineages of brood parasites have evolved mimetic eggshell coloration and patterning to circumvent host recognition. What is the mechanism of parasitic egg color mimicry at the chemical level? Mimetic egg coloration by Common Cuckoos Cuculus canorus is achieved by depositing similar concentrations of colorful pigments into their shells as their hosts. The mechanism of parasitic egg color mimicry at the chemical level in other lineages of brood parasites remains unexplored. Here we report on the chemical basis of egg color mimicry in an evolutionarily independent, and poorly studied, host-parasite system: the Neotropical Striped Cuckoo Tapera naevia and one of its hosts, the Rufous-and-white Wren Thryophilus rufalbus. In most of South America, Striped Cuckoos lay white eggs that are identical to those of local host species. In Central America, however, Striped Cuckoos lay blue eggs that match those of the Rufous-and-white Wren, suggesting that blue egg color in these cuckoo populations is an adaptation to mimic host egg appearance. Here we confirm that Striped Cuckoo eggs are spectrally similar to those of their hosts and consistently contain the same major eggshell pigment, biliverdin. However, wren eggshells lacked protoporphyrin, which was present in the parasitic cuckoo eggshells. Furthermore, biliverdin concentrations were significantly lower in cuckoo eggshells than in host eggshells. Similarity of host-parasite eggshell appearance, therefore, need not always be paralleled by a quantitative chemical match to generate effective visual mimicry in birds.

RESUMO

Introduction: Across specialties, surgeons over-prescribe opioids to patients after surgery. We aimed to develop and implement an evidence-based calculator to inform post-discharge opioid prescription size for gynecologic oncology patients after laparotomy. Methods: In 2021, open surgical gynecologic oncology patients were called 2-4 weeks after surgery to ask about their home opioid use. This data was used to develop a calculator for post-discharge opioid prescription size using two factors: 1) age of the patient, 2) oral morphine equivalents (OME) used by patients the day before hospital discharge. The calculator was implemented on the inpatient service from 8/21/22 and patients were contacted 2-4 weeks after surgery to again assess their opioid use at home. Results: Data from 95 surveys were used to develop the opioid prescription size calculator and are compared to 95 post-intervention surveys. There was no difference pre- to post-intervention in demographic data, surgical procedure, or immediate postoperative recovery. The median opioid prescription size decreased from 150 to 37.5 OME (p < 0.01) and self-reported use of opioids at home decreased from 22.5 to 7.5 OME (p = 0.05). The refill rate did not differ (12.6 % pre- and 11.6 % post-intervention, p = 0.82). The surplus of opioids our patients reported having at home decreased from 1264 doses of 5 mg oxycodone tabs in the pre-intervention cohort, to 490 doses in the post-intervention cohort, a 61 % reduction. Conclusions: An evidence-based approach for prescribing opioids to patients after laparotomy decreased the surplus of opioids we introduced into our patients' communities without impacting refill rates.

RESUMO

Although models of co-evolution between brood parasites and their hosts primarily focus upon the cost to hosts in the current reproductive bout, the impact of brood parasitism may carry over to future reproductive attempts by altering resource allocation. Glucocorticoid stress hormones help mediate resource allocation to reproduction, yet they have rarely been examined in brood parasitic systems. Here we determined if shifts in parental care and corticosterone had carry-over effects on future reproductive effort in the rufous-and-white wren (Thryophilus rufalbus), a host of the Central American striped cuckoo (Tapera naevia). We found that parasitized parents had significantly higher stress-induced, but not baseline, corticosterone than natural parents during the fledgling stage, which was associated with changes in parental care. The high investment in current reproduction while parasitized may be due to the value of fledged chicks in tropical systems. This maladaptive response by parasitized parents was associated with delayed re-nesting and a reduced likelihood of nesting in the subsequent breeding season. Although a reduction in future reproductive effort can result from a combination of factors, this work suggests that fitness costs of brood parasitism are mediated by changes in corticosterone and parental care behavior that carry over into subsequent breeding seasons.

RESUMO

INTRODUCTION: Greater than 70% of children who die in our institution annually die in an intensive care unit (ICU) setting. Family privacy, visitation policies, and an inability to perform religious rituals in the ICU are barriers to provide children with culturally competent, family-centered care when a child dies. The goal of this project was to profoundly understand family and staff experiences surrounding pediatric death in our institution to identify unique opportunities to design improved, novel delivery models of pediatric end of life (EOL) care. METHODS: This project utilized a structured process model based on the Vogel and Cagan's 4-phase integrated new product development process model. The 4 phases are identifying, understanding, conceptualizing, and realizing. We utilized an adaptation of this process model that relies on human-centered and design thinking methodologies in 3 phases: research, ideation, and refinement of a process or product opportunity. RESULTS: There were 2 primary results of this project: 5 process and opportunity areas to improve the EOL experience across the hospital, and a set of criteria and considerations for a dedicated EOL space. DISCUSSION: Sometimes, the best outcome we can provide for a child and their family is a peaceful, dignified death. This project utilized human-centered design to create improved process outcomes and to design a dedicated EOL space for children who die in the hospital. Offering grieving families quiet, private time with their child in a beautiful, dignified, peaceful location enables the beginning of improved bereavement outcomes for the family and staff.

RESUMO

Background: Location of death (LOD) is an important aspect of end-of-life (EOL) care. Adolescents and young adults (YAs) with pediatric malignancies are increasingly treated in pediatric institutions. YAs, generally defined as 18-39 years old, deserve specific attention because adults have unique developmental and social considerations compared with younger patients. Objective: The goal of this retrospective cohort study was to understand the effect of treatment by a pediatric oncology program on EOL experiences for YAs. Specifically, we examined LOD, hospice, and palliative care (PC) involvement in a cohort of YAs who died of cancer in a large, quaternary care pediatric hospital. Methods: This was a retrospective cohort study of patients ≥18 years of age, who died of cancer between January 1, 2010, and December 31, 2017. Standardized data were abstracted from the institutional cancer registry and the electronic medical record. Results: YAs in this cohort more commonly died in the hospital (54.9%). Lack of hospice involvement and the presence of a documented do-not-resuscitate (DNR) order were significantly associated with inpatient death. The majority of patients had long-standing PC involvement (95.8%, median 318 days), a DNR order (78.9%), and had enrolled in hospice care (60.6%) before death. Conclusions: These results suggest that a significant proportion of YAs with cancer remain inpatient for EOL care. Pediatric oncologists and PC teams may benefit from additional training in the unique psychosocial needs of YAs to optimize EOL care for these older patients.

RESUMO

BACKGROUND: Children receiving hospice and palliative care (HPC) differ from adults in important ways. Children are more likely to have rare diagnoses, less likely to have cancer, have longer lengths of stay on hospice, and are more likely to be technology dependent than adults. The National Consensus Project (NCP) in Palliative Care established domains of quality for HPC, but these domains have not been evaluated for applicability in children. OBJECTIVES: This study aims to establish consensus stakeholder-prioritized domains of high-quality pediatric home-based hospice and palliative care (HBHPC). DESIGN: Mixed methods design. SETTING/SUBJECTS: Providers from the Ohio Pediatric Palliative Care and End-of-life Network. MEASUREMENTS: Using a modified Delphi technique, providers were surveyed regarding the NCP quality domains for HPC. RESULTS: There was strong consensus on the applicability of each domain to the participants' practices (median scores ranged from 0.97 to 1.0 with interquartile ranges = 0). Consensus on the rank importance of the eight domains was not achieved. Qualitative data included challenges with NCP domain 3 (Psychological and Psychiatric Aspects of Care). It was recommended that titles should remain consistent with adult standards, but domain definitions should be broadened for pediatric HBHPC. Continuity and coordination of care should be added as a ninth domain of quality in pediatric HBHPC. CONCLUSIONS: All eight NCP domains were validated in pediatric HBHPC. A ninth domain, Continuity and Coordination of Care, was also added. Ranking the domains was not recommended as consensus indicated weighting them as equally integrated standards. Future studies are needed to evaluate parent- and patient-prioritized domains of quality in pediatric HBHPC and to validate and map pediatric-specific indicators to these domains.

RESUMO

Lipoblastoma is a benign myxoid neoplasm arising in young children that typically demonstrates adipose differentiation. It is often morphologically indistinguishable from primitive myxoid mesenchymal tumor of infancy (PMMTI), which is characterized by a well-circumscribed myxoid mass with a proliferation of primitive mesenchymal cells with mild cytologic atypia. PMMTI occurs in the first year of life and is known to have locally aggressive behavior. No specific genetic rearrangements have been reported to date. In contrast, the presence of PLAG1 (Pleomorphic Adenoma Gene 1) rearrangement is diagnostic for lipoblastoma. We hereby demonstrate the combined application of multiple approaches to tackle the diagnostic challenges of a rapidly growing neck tumor in a 3-month-old female. An incisional tumor biopsy had features of an undifferentiated, myxoid mesenchymal neoplasm mimicking PMMTI. However, tumor cells showed diffuse nuclear expression by immunohistochemical (IHC) stain. Conventional cytogenetic and fluorescence in situ hybridization (FISH) analyses as well as next generation sequencing (NGS) demonstrated evidence of PLAG1 rearrangement, confirming the diagnosis of lipoblastoma. This experience warrants that undifferentiated myxoid lipoblastoma can mimic PMMTI, and the combination of cytogenetic and molecular approaches is essential to distinguish these two myxoid neoplasms. Literature on lipoblastomas with relevant molecular and cytogenetic findings is summarized. Our case is the first lipoblastoma diagnosed with a PLAG1 fusion defined by NGS technology.

RESUMO

OBJECTIVE: Hospitalized children experience significant pain despite improvement efforts. This study was undertaken to better understand the epidemiology of acute pain in hospitalized children and the extent to which existing measures reveal targets for improving pain management. METHODS: A cross-sectional survey was used to audit pain assessment, intensity, prevalence, source, and treatment hospital-wide on a single day in 2011. Chart audits were performed on patients aged 0 to 21 years. All patients had the option to participate in a structured interview about their pain experience. RESULTS: The audit included 112 children, 47 of whom were interviewed. Pain prevalence obtained by child/parent interview (72%) was more than twice that documented by nurses (30%). Infants, but not cognitively impaired children, had significantly lower rates of pain detection and analgesic ordering than older age groups. Procedural pain was the most frequently cited source of pain among interviewed patients and was poorly addressed in the medical record. Fifty percent of children with documented moderate-to-severe pain received scheduled pain medications. More than one-third of interviewed patients would have wanted more pain medication if it could have been safely given. CONCLUSIONS: Specific gaps remain in the quality of pain management provided to hospitalized children. Focus on infant pain detection, assessment and management of procedural pain, and scheduled analgesic ordering are sensible targets for future process improvement efforts.
